TRUST EXPENSES
- --------------------------------------------------------------------------------

TRUST EXPENSES. As a shareholder of the Trust, you incur ongoing costs,
including management fees; service fees; and other Trust expenses. These
examples are intended to help you understand your ongoing costs (in dollars) of
investing in the Trust and to compare these costs with the ongoing costs of
investing in other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning
of the period and held for the entire 6-month period ended December 31, 2007.

ACTUAL EXPENSES. The first section of the table provides information about
actual account values and actual expenses. You may use the information in this
section, together with the amount you invested, to estimate the expense that you
paid over the period. Simply divide your account value by $1,000.00 (for
example, an $8,600.00 account value divided by $1,000.00 = 8.60), then multiply
the result by the number in the first section under the heading entitled
"Expenses Paid During Period" to estimate the expenses you paid on your account
during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The second section of the table
provides information about hypothetical account values and hypothetical expenses
based on the Trust's actual expense ratio, and an assumed rate of return of 5%
per year before expenses, which is not the actual return. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in the Trust and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Expenses are equal to the Trust's annualized expense ratio, multiplied by the
average account value over the period, multiplied by 184/365 (to reflect the
one-half year period). The annualized expense ratio based on the 6-month period
ended December 31, 2007 is as follows:

 EXPENSE RATIO
 --------------
     0.68%

The expense ratio reflects reduction to custodian expenses. The "Financial
Highlights" table in the Trust's financial statements, included in this report,
also show the gross expense ratio, without such waivers or reimbursements and
reduction to custodian expenses, if applicable.

                        29 | CENTENNIAL TAX EXEMPT TRUST



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

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

Centennial Tax Exempt 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 the maximum short-term interest
income exempt from federal income taxes that is consistent with low capital risk
and the maintenance of liquidity. The Trust's investment adviser is Centennial
Asset Management Corporation (the "Manager"), a subsidiary of OppenheimerFunds,
Inc. ("OFI").

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

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The net asset value of shares of the Trust is normally
determined twice each day, at 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.
Securities are valued at cost adjusted by the amortization of discount or
premium to maturity (amortized cost), which approximates market value. If
amortized cost is determined not to approximate market value, the fair value of
the portfolio securities will be determined under procedures approved by the
Trust's Board of Trustees.

- --------------------------------------------------------------------------------
SECURITIES ON A WHEN-ISSUED OR DELAYED DELIVERY BASIS. The Trust may purchase
securities on a "when-issued" basis, and may purchase or sell securities on a
"delayed delivery" basis. "When-issued" or "delayed delivery" refers to
securities whose terms and indenture are available and for which a market
exists, but which are not available for immediate delivery. Delivery and payment
for securities that have been purchased by the Trust on a when-issued basis
normally takes place within six months and possibly as long as two years or more
after the trade date. During this period, such securities do not earn interest,
are subject to market fluctuation and may increase or decrease in value prior to
their delivery. The purchase of securities on a when-issued basis may increase
the volatility of the Trust's net asset value to the extent the Trust executes
such transactions while remaining substantially fully invested. When the Trust
engages in when-issued or delayed delivery transactions, it relies on the buyer
or seller, as the case may be, to complete the transaction. Their failure to do
so may cause the Trust to lose the opportunity to obtain or dispose of the
security at a price and yield it considers advantageous. The Trust maintains
internally designated assets with a market value equal to or greater than the
amount of its purchase commitments. The Trust may also sell securities that it
purchased on a when-issued basis or forward commitment prior to settlement of
the original purchase.

As of December 31, 2007, the Trust had purchased securities issued on a
when-issued or delayed delivery basis and sold securities issued on a delayed
delivery basis as follows:

                                            WHEN-ISSUED OR DELAYED DELIVERY
                                                         BASIS TRANSACTIONS
     ----------------------------------------------------------------------
     Purchased securities                                       $43,004,601
     Sold securities                                              6,400,000


                        30 | CENTENNIAL TAX EXEMPT TRUST



- --------------------------------------------------------------------------------
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, including any net
realized gain on investments not offset by capital loss carryforwards, if any,
to shareholders, therefore, no federal income or excise tax provision is
required. The Trust files income tax returns in U.S. federal and applicable
state jurisdictions. The statute of limitations on the Trust's tax return
filings remain open for the three preceding fiscal reporting period ends.

      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.

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Board of Trustees has adopted a compensation
deferral 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 compensation deferral plan.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations and
may differ from U.S. generally accepted accounting principles, 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. Such interest expense and other custodian fees may be paid
with these earnings.

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

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 accounting
principles generally accepted in the United States of America 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 increases and
decreases in net assets from operations 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:



                         SIX MONTHS ENDED DECEMBER 31, 2007            YEAR ENDED JUNE 30, 2007

3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

MANAGEMENT FEES. Under the investment advisory agreement, the Trust pays the
Manager a management fee based on the daily net assets of the Trust at an annual
rate as shown in the following table:

                       FEE SCHEDULE
                       ----------------------------------
                       Up to $250 million          0.500%
                       Next $250 million           0.475
                       Next $250 million           0.450
                       Next $250 million           0.425
                       Next $250 million           0.400
                       Next $250 million           0.375
                       Next $500 million           0.350
                       Over $2 billion             0.325


                        32 | CENTENNIAL TAX EXEMPT TRUST



- --------------------------------------------------------------------------------
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. The Trust pays SSI a per account fee.
For the six months ended December 31, 2007, the Trust paid $256,336 to SSI for
services to the Trust.

- --------------------------------------------------------------------------------
SERVICE PLAN (12b-1) FEES. The Trust has adopted a Service Plan (the "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 (together with significant amounts
from the Manager's own resources) to pay dealers, brokers, banks and other
financial institutions periodically for providing personal service 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
Operations.

- --------------------------------------------------------------------------------
WAIVERS AND REIMBURSEMENTS OF EXPENSES. Under the investment advisory 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.

      SSI has voluntarily agreed to limit transfer and shareholder servicing
agent fees to 0.35% of average annual net assets of the Trust. This undertaking
may be amended or withdrawn at any time.

- --------------------------------------------------------------------------------
4. ILLIQUID SECURITIES

As of December 31, 2007, investments in securities included issues that are
illiquid. 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. 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.

- --------------------------------------------------------------------------------
5. RECENT ACCOUNTING PRONOUNCEMENT

In September 2006, Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 157, FAIR VALUE
MEASUREMENTS. This standard establishes a single authoritative definition of
fair value, sets out a framework for measuring fair value and expands
disclosures about fair value measurements. SFAS No. 157 applies to fair value
measurements already required or permitted by existing standards. SFAS No. 157
is effective for financial statements issued for fiscal years beginning after

5. RECENT ACCOUNTING PRONOUNCEMENT Continued

November 15, 2007, and interim periods within those fiscal years. As of December
31, 2007, the Manager does not believe the adoption of SFAS No. 157 will
materially impact the financial statement amounts; however, additional
disclosures may be required about the inputs used to develop the measurements
and the effect of certain of the measurements on changes in net assets for the
period.

BOARD APPROVAL OF THE TRUST'S INVESTMENT
ADVISORY AGREEMENT  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Each year, the Board of Trustees (the "Board"), including a majority of the
independent Trustees, is required to determine whether to renew the Trust's
investment advisory agreement (the "Agreement"). The Investment Company Act of
1940, as amended, requires that the Board request and evaluate, and that the
Manager provide, such information as may be reasonably necessary to evaluate the
terms of the Agreement. The Board employs an independent consultant to prepare a
report that provides information, including comparative information, that the
Board requests for that purpose. In addition, the Board receives information
throughout the year regarding Trust services, fees, expenses and performance.

      The Manager and the independent consultant provided information to the
Board on the following factors: (i) the nature, quality and extent of the
Manager's services, (ii) the investment performance of the Trust and the
Manager, (iii) the fees and expenses of the Trust, including comparative expense
information, (iv) the profitability of the Manager and its affiliates, including
an analysis of the cost of providing services, (v) whether economies of scale
are realized as the Trust grows and whether fee levels reflect these economies
of scale for Trust investors and (vi) other benefits to the Manager from its
relationship with the Trust. Outlined below is a summary of the principal
information considered by the Board as well as the Board's conclusions.

      The Board was aware that there are alternatives to retaining the Manager.

      NATURE, QUALITY AND EXTENT OF SERVICES. The Board considered information
about the nature and extent of the services provided to the Trust and
information regarding the Manager's key personnel who provide such services. The
Manager's duties include providing the Trust with the services of the portfolio
manager and the Manager's investment team, who provide research, analysis and
other advisory services in regard to the Trust's investments; securities trading
services; oversight of third party service providers; monitoring compliance with
applicable Trust policies and procedures and adherence to the Trust's investment
restrictions. The Manager is responsible for providing certain administrative
services to the Trust as well. Those services include providing and supervising
all administrative and clerical personnel who are necessary in order to provide
effective corporate administration for the Trust; compiling and maintaining
records with respect to the Trust's operations; preparing and filing reports
required by the Securities and Exchange Commission; preparing periodic reports
regarding the operations of the Trust for its shareholders; preparing proxy
materials for shareholder meetings; and preparing the registration statements
required by Federal and state securities laws for the sale of the Trust's
shares. The Manager also provides the Trust with office space, facilities and
equipment.


                        36 | CENTENNIAL TAX EXEMPT TRUST



      The Board also considered the quality of the services provided and the
quality of the Manager's resources that are available to the Trust. The Board
took account of the fact that the Manager has had over forty years of experience
as an investment adviser and that its assets under management rank it among the
top mutual fund managers in the United States. The Board evaluated the Manager's
administrative, accounting, legal and compliance services, and information the
Board has received regarding the experience and professional qualifications of
the Manager's key personnel and the size and functions of its staff providing
investment management services to the Trust. In its evaluation of the quality of
the portfolio management services provided, the Board considered the experience
of Cameron T. Ullyatt and the Manager's Money Market investment team and
analysts. Mr. Ullyatt has been the portfolio manager of the Trust since July
2006. The Board members also considered the totality of their experiences with
the Manager as directors or trustees of the Trust and other funds advised by the
Manager. In light of the foregoing, the Board concluded that the Trust benefits
from the services provided under the Agreement as a result of the Manager's
experience, reputation, personnel, operations, and resources.

      INVESTMENT PERFORMANCE OF THE MANAGER AND THE TRUST. During the year, the
Manager provided information on the investment performance of the Trust and the
Manager at each Board meeting, including comparative performance information.
The Board also reviewed information, prepared by the Manager and by the
independent consultant, comparing the Trust's historical performance to relevant
market indices and to the performance of other retail front-end load and no-load
tax-exempt money market funds. The Board noted that the Trust's one-year and
three-year performance were better than its peer group median, its five-year
performance was equal to its peer group median, and its ten-year performance was
below its peer group median.

      COSTS OF SERVICES AND PROFITS REALIZED BY THE MANAGER. The Board
considered information regarding the Manager's costs in serving as the Trust's
investment adviser, including the costs associated with the personnel and
systems necessary to manage the Trust, and information regarding the Manager's
profitability from its relationship with the Trust. The Board reviewed the fees
paid to the Manager and the other expenses borne by the Trust. The Board also
considered the comparability of the fees charged and the services provided to
the Trust to the fees and services for other clients or accounts advised by the
Manager. The independent consultant provided comparative data in regard to the
fees and expenses of the Trust, and other tax-exempt money market funds with
comparable asset levels and distribution features. The Board noted that under
the Investment Advisory 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 Board noted that the Trust's actual total
expenses are lower than its peer group median, though the contractual and actual
management fees are higher than its peer group median.

      ECONOMIES OF SCALE. The Board reviewed whether the Manager may realize
economies of scale in managing and supporting the Trust. The Board noted that
the Trust currently has management fee breakpoints, which are intended to share
economies of scale that may exist as the Trust grows with shareholders.

      OTHER BENEFITS TO THE MANAGER. In addition to considering the profits
realized by the Manager, the Board considered information that was provided
regarding the direct and indirect benefits the Manager receives as a result of
its relationship with the Trust, including compensation paid to the Manager's
affiliates. The Board also considered that the Manager must be able to pay and
retain experienced professional personnel at competitive rates to provide
quality services to the Trust and that maintaining the financial viability of
the Manager is important in order for the Manager to continue to provide
significant services to the Trust and its shareholders.

      CONCLUSIONS. These factors were also considered by the independent
Trustees meeting separately from the full Board, assisted by experienced counsel
to the Trust and to the independent Trustees. Trust counsel and the independent
Trustees' counsel are both independent of the Manager within the meaning and
intent of the Securities and Exchange Commission Rules.

      Based on its review of the information it received and its evaluations
described above, the Board, including a majority of the independent Trustees,
decided to continue the Agreement for another year. In arriving at this
decision, the Board considered all of the above information, and considered the
terms and conditions of the Agreement, including the management fee, in light of
all of the surrounding circumstances.

THE FUND'S GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

1.    The Fund's Governance Committee (the "Committee") will evaluate potential
      Board candidates to assess their qualifications. The Committee shall have
      the authority, upon approval of the Board, to retain an executive search
      firm to assist in this effort. The Committee may consider recommendations
      by business and personal contacts of current Board members and by
      executive search firms which the Committee may engage from time to time
      and may also consider shareholder recommendations. The Committee may
      consider the advice and recommendation of the Funds' investment manager
      and its affiliates in making the selection.

2.    The Committee shall screen candidates for Board membership. The Committee
      has not established specific qualifications that it believes must be met
      by a trustee nominee. In evaluating trustee nominees, the Committee
      considers, among other things, an individual's background, skills, and
      experience; whether the individual is



      an "interested person" as defined in the Investment Company Act of 1940;
      and whether the individual would be deemed an "audit committee financial
      expert" within the meaning of applicable SEC rules. The Committee also
      considers whether the individual's background, skills, and experience will
      complement the background, skills, and experience of other nominees and
      will contribute to the Board. There are no differences in the manner in
      which the Committee evaluates nominees for trustees based on whether the
      nominee is recommended by a shareholder.

3.    The Committee may consider nominations from shareholders for the Board at
      such times as the Committee meets to consider new nominees for the Board.
      The Committee shall have the sole discretion to determine the candidates
      to present to the Board and, in such cases where required, to
      shareholders. Recommendations for trustee nominees should, at a minimum,
      be accompanied by the following:

      o     the name, address, and business, educational, and/or other pertinent
            background of the person being recommended;

      o     a statement concerning whether the person is an "interested person"
            as defined in the Investment Company Act of 1940;

      o     any other information that the Funds would be required to include in
            a proxy statement concerning the person if he or she was nominated;
            and

      o     the name and address of the person submitting the recommendation
            and, if that person is a shareholder, the period for which that
            person held Fund shares.

      The recommendation also can include any additional information which the
      person submitting it believes would assist the Committee in evaluating the
      recommendation.

4.    Shareholders should note that a person who owns securities issued by
      Massachusetts Mutual Life Insurance Company (the parent company of the
      Funds' investment adviser) would be deemed an "interested person" under
      the Investment Company Act of 1940. In addition, certain other
      relationships with Massachusetts Mutual Life Insurance Company or its
      subsidiaries, with registered broker-dealers, or with the Funds' outside
      legal counsel may cause a person to be deemed an "interested person."

5.    Before the Committee decides to nominate an individual as a trustee,
      Committee members and other directors customarily interview the individual
      in person. In addition, the individual customarily is asked to complete a
      detailed questionnaire which is designed to elicit information which must
      be disclosed under SEC and stock exchange rules and to determine whether
      the individual is subject to any statutory disqualification from serving
      as a trustee of a registered investment company.



ITEM 11. CONTROLS AND PROCEDURES.

Based on their evaluation of the registrant's disclosure controls and procedures
(as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR
270.30a-3(c)) as of 12/31/2007, the registrant's principal executive officer and
principal financial officer found the registrant's disclosure controls and
procedures to provide reasonable assurances that information required to be
disclosed by the registrant in the reports that it files under the Securities
Exchange Act of 1934 (a) is accumulated and communicated to registrant's
management, including its principal executive officer and principal financial
officer, to allow timely decisions regarding required disclosure, and (b) is

likely to materially affect, the registrant's internal control over financial
reporting.
