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

- --------------------------------------------------------------------------------
 1. SIGNIFICANT ACCOUNTING POLICIES
 Centennial California Tax Exempt Trust (the Trust) is registered under the
 Investment Company Act of 1940, as amended, as a non-diversified, open-end
 management investment company. The Trust's investment objective is to seek the
 maximum current interest income exempt from federal and California personal
 income taxes for individ- ual investors as is consistent with the preservation
 of capital. The Trust's investment advisor is Centennial Asset Management
 Corporation (the Manager), a subsidiary of OppenheimerFunds, Inc. (OFI).
    The following is a summary of significant accounting policies consistently
 followed by the Trust.
- --------------------------------------------------------------------------------
 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.
- --------------------------------------------------------------------------------
 SECURITY CREDIT RISK. There are certain risks arising from geographic
 concentration in any state. Certain revenue or tax related events in a state
 may impair the ability of certain issuers of municipal securities to pay
 principal and interest on their obligations.
- --------------------------------------------------------------------------------
 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
                 INVESTMENT INCOME     LONG-TERM GAIN      CARRYFORWARD 1
                 --------------------------------------------------------
                 $34,105                          $--             $13,044

 1. As of June 30, 2004, the Trust had $13,044 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, 2004, details of the capital
 loss carryforward were as follows:

                              EXPIRING
                              ----------------------
                              2012           $13,044

 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.


          12 | CENTENNIAL CALIFORNIA TAX EXEMPT TRUST




 The tax character of distributions paid during the years ended June 30, 2004
 and June 30, 2003 were as follows:

                                             YEAR ENDED      YEAR ENDED
                                          JUNE 30, 2004   JUNE 30, 2003
                 ------------------------------------------------------
                 Distributions paid from:
                 Exempt-interest dividends     $309,706        $805,721

- --------------------------------------------------------------------------------
 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 does purchase 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.
- --------------------------------------------------------------------------------
 EXPENSE OFFSET ARRANGEMENT. The reduction of custodian fees, if applicable,
 represents earnings on cash balances maintained by the Trust.
- --------------------------------------------------------------------------------
 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

- --------------------------------------------------------------------------------
 TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF CENTENNIAL CALIFORNIA TAX EXEMPT
 TRUST:
 We have audited the accompanying statement of assets and liabilities of
 Centennial California Tax Exempt Trust, including the statement of investments,
 as of June 30, 2004, 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 the periods indicated.
 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. An audit includes examining, on a test basis, evidence supporting
 the amounts and disclosures in the financial statements. Our procedures
 included confirmation of securities owned as of June 30, 2004, by
 correspondence with the custodian and brokers; where replies were not received
 from brokers, we performed other auditing procedures. An audit also includes
 assessing the accounting principles used and significant estimates made by
 management, as well as evaluating the overall financial statement presentation.
 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 California Tax Exempt Trust as of June 30, 2004, 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 the
 periods indicated, in conformity with accounting principles generally accepted
 in the United States of America.

ITEM 9.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         The Board is responsible for approving nominees for election as
trustees. To assist in this task, the Board has designated the Audit Committee
as the nominating committee for the Board. It reviews and recommends nominees to
the Board. The Committee is comprised entirely of disinterested trustees as
defined in Section 2(a)(19) of the Investment Company Act of 1940.

The Audit Committee charter describes the responsibilities of the Committee in
nominating candidates for election as independent Trustees of the Registrant.
The Registrant's Board has adopted a written charter for the Committee. A
current copy of the Audit Committee charter is available to shareholders on the
OppenheimerFunds website at www.oppenheimerfunds.com.

Under the current policy, if the Board determines that a vacancy exists or is
likely to exist on the Board, the Audit Committee of the Board will consider
candidates for Board membership including recommended by Registrant
shareholders. The Audit Committee will consider nominees recommended by
independent Board members or recommended by any other Board members including
Board members affiliated with the Registrant's investment advisors. The
Committee may, upon Board approval, retain an executive search firm to assist in
screening potential candidates. Upon Board approval, the Audit Committee may
also use the services of legal, financial, or other external counsel that it
deems necessary or desirable in the screening process. Shareholders wishing to
submit a nominee for election to the Board may do so by mailing their submission
to the offices of OppenheimerFunds, Inc., 6803 South Tucson Way, Centennial, CO
80112, to the attention of the Board of Trustees of the named Registrant, c/o
the Secretary of the Registrant.

The Committee's process for identifying and evaluating nominees for trustees
includes a number of factors. In screening candidates for board membership,
whether the candidate is suggested by Board members, shareholders or others, the
Committee considers the candidate's professional experience, soundness of
judgment, integrity, ability to make independent, analytical inquiries,
collegiality, willingness and ability to devote the time required to perform
Board activities adequately, ability to represent the interests of all
shareholders of the Registrant, and diversity relative to the board's
composition. Candidates are expected to provide a mix of attributes, experience,
perspective and skills necessary to effectively advance the interests of
shareholders.
