ZACK, ESQ. OPPENHEIMERFUNDS, INC. TWO WORLD FINANCIAL CENTER, NEW YORK, NEW YORK 10281-1008 (Name and address of agent for service) Registrant's telephone number, including area code: (303) 768-3200 Date of fiscal year end: JUNE 30 Date of reporting period: DECEMBER 31, 2005 ITEM 1. REPORTS TO STOCKHOLDERS. FUND EXPENSES - -------------------------------------------------------------------------------- FUND 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, 2005. ACTUAL EXPENSES. The "actual" lines of the table provide information about actual account values and actual expenses. You may use the information on this line 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 "actual" line 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 "hypothetical" lines of the table provide 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 Trust's 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. 5 | CENTENNIAL TAX EXEMPT TRUST FUND EXPENSES - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- BEGINNING ENDING EXPENSES ACCOUNT ACCOUNT PAID DURING VALUE VALUE 6 MONTHS ENDED (7/1/05) (12/31/05) DECEMBER 31, 2005 - -------------------------------------------------------------------------------- Actual $1,000.00 $1,010.60 $3.44 - -------------------------------------------------------------------------------- Hypothetical 1,000.00 1,021.79 3.46 Hypothetical assumes 5% annual return before expenses.

SEE ACCOMPANYING NOTES TO FINANCIAL STATEMENTS. 21 | 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 advisor is Centennial Asset Management Corporation (the Manager), a subsidiary of OppenheimerFunds, Inc. (OFI). The following is a summary of significant accounting policies consistently followed by the Trust. - -------------------------------------------------------------------------------- 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. - -------------------------------------------------------------------------------- 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. 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 estimated capital loss carryforward represents carryforward as of the end of the last fiscal year, increased for losses deferred under tax accounting rules to the current fiscal year and is increased or decreased by capital losses or gains realized in the first six months of the current fiscal year. During the six months ended December 31, 2005, it is estimated that the Trust will utilize $5,544 of capital loss carryforward to offset realized capital gains. During the year ended June 30, 2005, the Trust utilized $96,274 of capital loss carryforward to offset realized capital gains. As of June 30, 2005, the Trust had available for federal income tax purposes unused capital loss carryforward as follows: EXPIRING --------------------------- 2012 $5,544 --------------------------- - -------------------------------------------------------------------------------- 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 22 | CENTENNIAL TAX EXEMPT TRUST 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. 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. - -------------------------------------------------------------------------------- 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: SIX MONTHS ENDED DECEMBER 31, 2005 YEAR ENDED JUNE 30, 2005 SHARES AMOUNT SHARES AMOUNT - -------------------------------------------------------------------------------------------------------- Sold 2,291,670,990 $ 2,291,670,404 5,467,251,055 $ 5,467,251,055 Dividends and/or distributions reinvested 16,554,917 16,555,503 20,503,644 20,503,644 Redeemed (2,412,866,419) (2,412,866,419) (5,565,437,814) (5,565,437,814) - -------------------------------------------------------------------------------------------------------- Net decrease (104,640,512) $ (104,640,512) (77,683,115) $ (77,683,115) =========================================================================== 23 | CENTENNIAL TAX EXEMPT TRUST NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES MANAGEMENT FEES. Management fees paid to the Manager were in accordance with the investment advisory agreement with the Trust which provides for a fee at an annual rate of 0.50% of the first $250 million of the Trust's net assets, 0.475% of the next $250 million, 0.45% of the next $250 million, 0.425% of the next $250 million, 0.40% of the next $250 million, 0.375% of the next $250 million, 0.35% of the next $500 million and 0.325% of net assets in excess of $2 billion. - -------------------------------------------------------------------------------- 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 six months ended December 31, 2005, the Trust paid $250,840 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 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. 24 | CENTENNIAL TAX EXEMPT TRUST PORTFOLIO PROXY VOTING POLICIES AND PROCEDURES; UPDATES TO STATEMENTS OF INVESTMENTS Unaudited - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- The Fund has adopted Portfolio Proxy Voting Policies and Procedures under which the Fund votes proxies relating to securities ("portfolio proxies") held by the Fund.

Information on the operation of the Public Reference Room may be obtained by calling 1-800-SEC-0330. 25 | CENTENNIAL TAX EXEMPT TRUST 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, 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. NATURE, QUALITY, AND EXTENT OF SERVICES. The Board considered information on the nature and extent of the services provided to the Trust by the Manager and by OppenheimerFunds, Inc., the Manager's parent company, and information regarding the key personnel that 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 that 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. 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 26 | CENTENNIAL TAX EXEMPT TRUST the Manager has been an investment advisor since 1978 and that the Manager's and its parent's assets under management rank 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. The Board also considered compliance reports from the Trust's Chief Compliance Officer. In its evaluation of the quality of the portfolio management services provided, the Board considered the experience of John Bonnell and the Manager's money market investment team and analysts. Mr. Bonnell has had over 17 years of experience managing money market, equity, fixed income and municipal/tax-exempt investments. 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 TRUST. During the year, the Manager provided information on the performance of the Trust 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 tax-exempt money market funds. The Board noted that the Trust's one-year performance was slightly better than its peer group median. However its three-year, five-year and ten-year performance were 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 evaluated 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, other tax-exempt money market funds and other funds with comparable asset levels and distribution features. 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 Board noted that the Trust's actual 27 | CENTENNIAL TAX EXEMPT TRUST BOARD APPROVAL OF THE TRUST'S INVESTMENT ADVISORY AGREEMENT Unaudited / Continued management fees are lower than its peer group median but higher than its peer group average, however, its contractual management fees and total expenses are both lower than its peer group median and average. In light of this, the Board concluded that the management fee was reasonable. ECONOMIES OF SCALE. The Board considered whether the Manager may realize economies of scale in managing and supporting the Trust, whether those economies of scale benefit the Trust's shareholders and the current level of Trust assets in relation to the Trust's management fee breakpoints, which are intended to share with shareholders economies of scale that may exist as the Trust grows. 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 the nature and quality of services provided by affiliates of the Manager, which it reviews at other times during the year in connection with the renewal of the Trust's service agreements. The Board considered that the Manager must be able to pay and retain experienced professional personnel at competitive rates to provide 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 advisory agreement for another year. In arriving at this decision, the Board did not single out any factor or factors as being more important than others, but considered all of the factors together. The Board judged the terms and conditions of the advisory agreement, including the management fee, in light of all of the surrounding circumstances. 28 | CENTENNIAL TAX EXEMPT TRUST ITEM 2.

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: 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 December 31, 2005, 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.
