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

- --------------------------------------------------------------------------------
 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 individual 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. 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, 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.
    As of December 31, 2003, the Trust had available for federal income tax
 purposes an estimated unused capital loss carryforward of $13,044. This
 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, 2003 and the year ended June 30, 2003, the Trust
 used $0 and $0, respectively, of carryforward to offset capital gains realized.
- --------------------------------------------------------------------------------
 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. Under the plan, deferred amounts are treated as
 though equal dollar amounts had been invested in shares of the Trust or are
 invested in other Oppenheimer funds selected by the Trustee. 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.

NOTES TO FINANCIAL STATEMENTS  Unaudited / Continued
- --------------------------------------------------------------------------------

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