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 June 30, 2008.

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.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as front-end
or contingent deferred sales charges (loads), or a $12.00 fee imposed annually
on accounts valued at less than $500.00 (subject to exceptions described in the
Statement of Additional Information). Therefore, the "hypothetical" section of
the table is useful in comparing ongoing costs only, and will not help you
determine the relative total costs of owning different funds. In addition, if
these transactional costs were included, your costs would have been higher.

Expenses are equal to the Trust's annualized expense ratio, multiplied by the
average account value over the period, multiplied by 182/366 (to reflect the
one-half year period). The annualized expense ratio based on the 6-month period
ended June 30, 2008 is as follows:

EXPENSE RATIO
- -------------
    0.64%


The expense ratio reflects reduction to custodian fees. 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.

                       F26 | CENTENNIAL TAX EXEMPT TRUST



NOTES TO FINANCIAL STATEMENTS

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 June 30, 2008, 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
                  --------------
               
Sold securities     $8,000,000

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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 Trust
files income tax returns in U.S. federal and applicable state jurisdictions. The
statute of limitations on the Trust's tax return filings generally remain open
for the three preceding fiscal reporting period ends.

The tax components of capital shown in the following table 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
INVESTMENT INCOME   LONG-TERM GAINS   CARRYFORWARD(1,2)

    $835,690            $48,355              $--


(1.) During the fiscal year ended June 30, 2008, the Trust did not utilize any
     capital loss carryforwards.

(2.) During the fiscal year ended June 30, 2007, the Trust did not utilize any
     capital loss carryforwards.

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, 2008 and
June 30, 2007 was as follows:



                              YEAR ENDED      YEAR ENDED

                             ===========     ===========


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


                        F28 | CENTENNIAL TAX EXEMPT TRUST


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.

INVESTMENT INCOME. Interest income is recognized on an accrual basis. Discount
and premium, which are included in interest income on the Statement of
Operations, are amortized or accreted daily.

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.

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.

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
Next $2 billion       0.325


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 year ended June 30, 2008, the
Trust paid $469,711 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.


                  F30 | CENTENNIAL TAX EXEMPT TRUST



     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 June 30, 2008, 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 an applicable footnote on the Statement
of Investments.

5. RECENT ACCOUNTING PRONOUNCEMENTS

In September 2006, the 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 November 15, 2007, and interim periods within those fiscal
years. As of June 30, 2008, 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.

     In March 2008, FASB issued SFAS No. 161, DISCLOSURES ABOUT
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. This standard requires
enhanced disclosures about derivative and hedging activities,
including qualitative disclosures about how and why the Trust uses
derivative instruments, how these activities are accounted for, and
their effect on the Trust's financial position, financial performance
and cash flows. SFAS No. 161 is effective for financial statements
issued for fiscal years beginning after November 15, 2008 and interim
periods within those fiscal years. At this time, management is
evaluating the implications of SFAS No. 161 and its impact on the
Trust's financial statements and related disclosures.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF CENTENNIAL TAX EXEMPT
TRUST: We have audited the accompanying statement of assets and
liabilities of Centennial Tax Exempt Trust (the "Trust"), including
the statement of investments, as of June 30, 2008, 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
period then ended. 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 audits included
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,
2008, 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 the Trust as of June 30, 2008,
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 period
then ended, in conformity with accounting principles generally
accepted in the United States of America.

FEDERAL INCOME TAX INFORMATION Unaudited

In early 2008, if applicable, shareholders of record received
information regarding all taxable dividends and distributions paid to
them by the Trust during calendar year 2007. Regulations of the U.S.
Treasury Department require the Trust to report this information to
the Internal Revenue Service.

     Recent tax legislation allows a regulated investment company to
designate distributions not designated as capital gain distributions,
as either interest related dividends or short-term capital gain
dividends, both of which are exempt from the U.S. withholding tax
applicable to non U.S. taxpayers. For the fiscal year ended June 30,
2008, $174,876 or 100% of the short-term capital gain distribution
paid and to be paid by the Trust qualifies as a short-term capital
gain dividend.

     The foregoing information is presented to assist shareholders in
reporting distributions received from the Trust to the Internal
Revenue Service. Because of the complexity of the federal regulations
which may affect your individual tax return and the many variations
in state and local tax regulations, we recommend that you consult
your tax advisor for specific guidance.

ITEM 10. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

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:

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

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

     -    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

     -    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 06/30/2008, 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
recorded, processed, summarized and reported, within the time periods specified
in the rules and forms adopted by the U.S. Securities and Exchange Commission.



There have been no changes in the registrant's internal controls over financial
reporting that occurred during the registrant's second fiscal quarter of the
period covered by this report that have materially affected, or are reasonably
likely to materially affect, the registrant's internal control over financial
reporting.
