FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE FUND PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF
THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED JULY 31, 2006, FOLLOWED BY A
GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE BROAD-BASED
MARKET INDEX.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. Across the past 12 months, the Fund
performed extremely well for shareholders seeking tax-free income as its yield
compared very favorably to those earned by its competitors and by other fixed
income investments. The Fund's Class A shares produced a distribution yield of
5.16% (without sales charges) as of July 31, 2006. Lipper Analytical Services,
Inc., an independent mutual fund rating service, reported an average
distribution yield of 3.86% among the 122 funds in its California Municipal Debt
Funds category as of the same date. 1 The Fund's holdings represent a wide
variety of industry sectors and credit qualities, and tax-free income generated
by this diverse portfolio made up 100% of the Fund's positive total return for
the period. Strong asset growth fueled the Fund's strategy of building
diversification, and by the end of the report period the number of holdings in
the Fund rose to 554, from 335 a year earlier.

      The Fund's income-oriented approach continued to provide significant
benefit to our investors in this report period. In the year ended July 31, 2006,
the Fund's Class A shares generated a total return of 4.74% without sales charge
(-0.24% with sales charge). By comparison, its primary benchmark, the Lehman
Brothers Municipal Bond Index, produced a total return of 2.55% for the
period. 2

      In this period, the prices of lower-rated municipal bonds have increased
relative to prices of higher-grade bonds, a condition known as "credit spread
tightening." Concurrently, the difference between yields on shorter- and
longer-term municipal securities has declined. These conditions combined to
create dividend pressure midway through this report period. The monthly
distribution, which had held steady at $0.052 per Class A share for the first
seven months of the report period, was reduced to $0.049 per Class A share on
February 22, 2006, and distributions for other share classes were adjusted
accordingly. In all, distributions per Class A share totaled 60.9 cents for the
fiscal year ended July 31, 2006. Investors should note that dividend reductions
do not change the Fund's net asset value per share and that this dividend
reduction was not the result of any material defaults of bonds in the Fund's
portfolio.

                  12 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND


      During this period of generally higher prices of lower-rated and non-rated
municipal securities, the Fund shifted a larger portion of its assets to
higher-quality bonds. For example, as of July 31, 2006, AAA- and AA-rated paper
represented more than one-quarter of the portfolio's market value, up nearly 15%
from the same date last year.

      The breadth of California's economic recovery during the past 12 months
has continued to foster optimism at the three major credit ratings agencies,
each of which raised the state's General Obligation debt rating one "notch." At
the end of this report period, the credit rating for California debt was A1
according to Moody's Investors Service and A+ according to both Standard &
Poor's and Fitch Ratings. Among the factors cited in these upgrades were a sharp
rise in tax collections and the state's progress in reducing fiscal imbalances.

      During this period, the Fund's holdings in Master Settlement Agreement
("MSA") tobacco-backed bonds, which accounted for 24.2% of Fund investments as
of July 31, 2006, have contributed strongly to the Fund's yield and total return
performance. MSA bonds are backed by the issuing State's (or U.S. territory's)
share of proceeds from a national litigation settlement with tobacco
manufacturers.

      The litigation environment in the past 12 months has continued to improve
for the tobacco industry and, by extension, for MSA bonds. On December 15, 2005,
the Illinois Supreme Court reversed a $10.1 billion judgment against Philip
Morris USA that had been awarded by a lower court in 2003. Near the end of the
period the Florida Supreme Court upheld an appellate court's reversal of a $145
billion judgment against cigarette manufacturers in the long-running Engle case.
An action brought by the U.S. government against the tobacco industry is still
pending, but we believe that final resolution of this matter will not carry
negative consequences for the Fund's MSA bonds.

      MSA bond prices rose early in the report period amid widespread market
speculation that these bonds might be "pre-refunded" by their issuers. In a
pre-refunding, a municipality issues a new bond whose proceeds are escrowed in
U.S. Government bonds and earmarked to pay off another previously issued--but
not yet callable--municipal bond. When an outstanding bond is pre-refunded, its
price generally rises significantly. During this report period, several
MSA-backed bonds were pre-refunded--including bonds issued by the Northern
California and Southern California tobacco securitization authorities for use in
the City of Sacramento and San Diego County, respectively--and their prices
rose. As a result, these holdings contributed to the Fund's yield and net asset
value for the period. After the pre-refunding event, the Fund sold its holdings
at a gain over their purchase price. The Fund also took strategic advantage of
tax loss carry-forwards to ensure that no capital gain was distributed to
shareholders. Pre-refunding of MSA-backed tobacco

FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

bonds provides a particularly good example of how our yield-oriented investment
strategy can result in both yield and price appreciation for individual bonds,
generating attractive total return.

      The airline sector continues to have a positive impact on Fund
performance. Airline-backed bonds comprised 1.9% of the Fund's investments as of
July 31, 2006, with the great majority of these holdings backed by payments from
American Airlines. Growing passenger traffic, capacity control and increased
fares have helped to stabilize the financial picture at American Airlines.
Despite increased fuel prices, American posted second-quarter profits, after
years of losses, and many analysts expect this carrier to return to
profitability in 2006. The Fund's holdings in airline sector bonds have been a
positive contributor to total return in this report period.

      New Fund holdings have included many municipal bonds issued to finance the
infrastructure of new real estate development projects during this report
period. These bonds, sometimes known as "Special Tax" and "Special Assessment"
bonds, represented more than one-third of the Fund's investments as of July 31,
2006. We believe that their credit structure can be particularly advantageous
for municipal bond investors, as the payments that secure the bonds are on
parity with real estate taxes. We use our own in-house research to identify
bonds that we believe will create value for shareholders, and choose to invest
in bonds for a broad mix of residential, commercial, retail, and office
properties throughout California. We also diversify across time, picking
projects in different stages of development, and this broad diversification
serves to reduce the portfolio's exposure to risk.

      During this report period, financial difficulties in the Commonwealth of
Puerto Rico led Moody's Investors Services and Standard & Poor's to issue
downgrades on government-issued bonds. While bonds issued by Puerto Rico
underperformed as prices were weakened by the broader market's reaction to
government overspending and budget deficits, we believe that the government's
more recent decisions to raise taxes and reinforce its financial structure will
ultimately strengthen municipal bonds that the Fund continues to own. As we have
continued to monitor developments in Puerto Rico, we have taken advantage of
market weakness to add to positions in these bonds at favorable prices.

      The Fund has reduced holdings in municipal inverse-floating-rate
securities during this report period. These holdings are generally highly
liquid, tax-exempt securities whose interest payments move inversely to
short-term interest rates: stated differently, an increase in short-term
interest rates causes a decline in income from these securities. As the yield
curve flattened and long-term interest rates rose slightly during this period,
these securities offered higher-than-market rates but generated less income than
in previous periods.


                  14 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND


The Fund's diversified portfolio includes a variety of bond types, structures
and maturities, in an effort to mute the effects of any one variety. New
municipal bond issues during this report period offered fewer higher-yielding
municipal bonds, which typically possess a favorable balance of risk and reward
for the Fund. In an effort to minimize overall income volatility in the Fund
across the past 12 months, we continued to invest in select premium-coupon,
callable bonds that may remain outstanding through periods of rising short-term
interest rates.

      The "Rochester style" of municipal bond investing is flexible and
responsive to market conditions; our strategies are intended to balance many
different types of risk to reduce exposure to any individual risk. We continue
to comb the market for bonds that offer attractive yields, and to monitor
developing market conditions. Notwithstanding the change in the Fund's dividend
distribution, we believe that shareholders will continue to benefit from highly
competitive yields as market conditions continue to develop. Shareholders should
note that market conditions during this report period did not affect the Fund's
overall investment strategies or cause it to pay any capital gain distribution.

COMPARING THE FUND'S PERFORMANCE TO THE MARKET. The graphs that follow show the
performance of a hypothetical $10,000 investment in each class of shares of the
Fund held until July 31, 2006. In the case of Class A, Class B and Class C
shares, performance is measured over a ten-year period. The Fund's performance
reflects the deduction of the maximum initial sales charge on Class A shares,
the applicable contingent deferred sales charge on Class B and Class C shares,
and reinvestments of all dividends and capital gains distributions. Past
performance cannot guarantee future results.

      The Fund's performance is compared to the performance of the Lehman
Brothers Municipal Bond Index, an unmanaged index of a broad range of investment
grade municipal bonds that is widely regarded as a measure of the performance of
the general municipal bond market. Index performance reflects the reinvestment
of income but does not consider the effect of transaction costs, and none of the
data in the graphs shows the effect of taxes. The Fund's performance reflects
the effects of the Fund's business and operating expenses. While index
comparisons may be useful to provide a benchmark for the Fund's performance, it
must be noted that the Fund's investments are not limited to the investments in
the index.

NOTES
- --------------------------------------------------------------------------------

TOTAL RETURNS INCLUDE CHANGES IN SHARE PRICE AND REINVESTMENT OF DIVIDENDS AND
CAPITAL GAINS DISTRIBUTIONS IN A HYPOTHETICAL INVESTMENT FOR THE PERIODS SHOWN.
CUMULATIVE TOTAL RETURNS ARE NOT ANNUALIZED. THE FUND'S TOTAL RETURNS SHOWN DO
NOT REFLECT THE DEDUCTION OF INCOME TAXES ON AN INDIVIDUAL'S INVESTMENT. TAXES
MAY REDUCE YOUR ACTUAL INVESTMENT RETURNS ON INCOME OR GAINS PAID BY THE FUND OR
ANY GAINS YOU MAY REALIZE IF YOU SELL YOUR SHARES. THIS ANNUAL REPORT MUST BE
PRECEDED OR ACCOMPANIED BY THE CURRENT PROSPECTUS OF THE OPPENHEIMER CALIFORNIA
MUNICIPAL FUND. BEFORE INVESTING IN ANY OF THE OPPENHEIMER FUNDS, INVESTORS
SHOULD CAREFULLY CONSIDER A FUND'S INVESTMENT OBJECTIVES, RISKS, CHARGES AND
EXPENSES. FUND PROSPECTUSES CONTAIN THIS AND OTHER INFORMATION ABOUT THE FUNDS.
FOR MORE INFORMATION, ASK YOUR FINANCIAL ADVISOR, CALL US AT 1.8000.525.7048, OR
VISIT OUR WEBSITE AT WWW.OPPENHEIMERFUNDS.COM. READ PROSPECTUSES CAREFULLY
BEFORE INVESTING.

THE FUND'S INVESTMENT STRATEGY AND FOCUS CAN CHANGE OVER TIME. THE MENTION OF
SPECIFIC FUND HOLDINGS DOES NOT CONSTITUTE A RECOMMENDATION BY OPPENHEIMERFUNDS,
INC.

CLASS A shares of the Fund were first publicly offered on 11/3/88. The
average annual total returns are shown net of the applicable 4.75% maximum
initial sales charge. The Fund's maximum sales charge for Class A shares was
lower prior to 1/31/86, so actual performance may have been higher.

CLASS B shares of the Fund were first publicly offered on 5/3/93. The average
annual total returns are shown net of the applicable contingent deferred sales
charge of 5% (1-year) and 2% (5-year). Because Class B shares convert to Class A
shares 72 months after purchase, the 10-year return for Class B uses Class A
performance for the period after conversion. Class B shares are subject to an
annual 0.75% asset-based sales charge.

CLASS C shares of the Fund were first publicly offered on 11/1/95. The average
annual total returns are shown net of the applicable 1% contingent deferred
sales charge for the 1-year period. Class C shares are subject to an annual
0.75% asset-based sales charge.

An explanation of the calculation of performance is in the Fund's Statement of
Additional Information.

FUND EXPENSES
- --------------------------------------------------------------------------------

FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1)
transaction costs, which may include sales charges (loads) on purchase payments,
contingent deferred sales charges on redemptions; and redemption fees, if any;
and (2) ongoing costs, including management fees; distribution and service fees;
and other Fund expenses. These examples are intended to help you understand your
ongoing costs (in dollars) of investing in the Fund 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 July 31, 2006.

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 for the class of shares you hold, 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 Fund's actual expense ratio for each class of shares, and
an assumed rate of return of 5% per year before expenses, which is not the
Fund'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 Fund and other funds. To do so, compare this 5% hypothetical example for
the class of shares you hold 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


                  20 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND


the Statement of Additional Information). Therefore, the "hypothetical" lines of
the table are 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.

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer California Municipal Fund (the Fund) is registered under the
Investment Company Act of 1940, as amended, as a non-diversified, open-end
management investment company. The Fund's investment objective is to seek as
high a level of current interest income exempt from federal and California
income taxes for individual investors as is consistent with preservation of
capital. The Fund's investment advisor is OppenheimerFunds, Inc. (the Manager).

      The Fund offers Class A, Class B and Class C shares. Class A shares are
sold at their offering price, which is normally net asset value plus a front-end
sales charge. Class B and Class C shares are sold without a front-end sales
charge but may be subject to a contingent deferred sales charge (CDSC). All
classes of shares have identical rights and voting privileges with respect to
the Fund in general and exclusive voting rights on matters that affect that
class alone. Earnings, net assets and net asset value per share may differ due
to each class having its own expenses, such as transfer and shareholder
servicing agent fees and shareholder communications, directly attributable to
that class. Class A, B and C have separate distribution and/or service plans.
Class B shares will automatically convert to Class A shares six years after the
date of purchase.

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

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The Fund calculates the net asset value of its shares as
of the close of the New York Stock Exchange (the "Exchange"), normally 4:00 P.M.
Eastern time, on each day the Exchange is open for business. Securities may be
valued primarily using dealer-supplied valuations or a portfolio pricing service
authorized by the Board of Trustees. Securities listed or traded on National
Stock Exchanges or other domestic exchanges are valued based on the last sale
price of the security traded on that exchange prior to the time when the Fund's
assets are valued. Securities traded on NASDAQ are valued based on the closing
price provided by NASDAQ prior to the time when the Fund's assets are valued. In
the absence of a sale, the security is valued at the last sale price on the
prior trading day, if it is within the spread of the closing "bid" and "asked"
prices, and if not, at the closing bid price. Securities traded on foreign
exchanges are valued based on the last sale price on the principal exchange on
which the security is traded, as identified by the portfolio pricing service,
prior to the time when the Fund's assets are valued. In the absence of a sale,
the security is valued at the official closing price on the principal exchange.
Corporate, government and municipal debt instruments having a remaining maturity
in excess of sixty days and all mortgage-backed securities will be valued at the
mean between the "bid" and "asked" prices. Futures contracts traded on a
commodities or futures exchange will be valued at the final settlement price or
official closing price on the principal exchange as reported by such principal
exchange at its trading session ending at, or most recently prior to, the time
when the Fund's assets are valued. Securities (including restricted securities)
for which market quotations are not


                  48 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND


readily available are valued at their fair value. Foreign and domestic
securities whose values have been materially affected by what the Manager
identifies as a significant event occurring before the Fund's assets are valued
but after the close of their respective exchanges will be fair valued. Fair
value is determined in good faith using consistently applied procedures under
the supervision of the Board of Trustees. Short-term "money market type" debt
securities with remaining maturities of sixty days or less are valued at
amortized cost (which approximates market value).

- --------------------------------------------------------------------------------
INVERSE FLOATING RATE SECURITIES. The Fund invests in inverse floating rate
securities that pay interest at a rate that varies inversely with short-term
interest rates. Certain of these securities may be leveraged, whereby the
interest rate varies inversely at a multiple of the change in short-term rates.
As interest rates rise, inverse floaters produce less current income. The price
of such securities is more volatile than comparable fixed rate securities. The
Fund will not invest more than 20% of its total assets in inverse floaters.
Inverse floaters amount to $121,996,289 as of July 31, 2006, which represents
7.81% of the Fund's total assets.

- --------------------------------------------------------------------------------
SECURITIES ON A WHEN-ISSUED BASIS OR FORWARD COMMITMENT. Delivery and payment
for securities that have been purchased by the Fund on a when-issued basis or
forward commitment can take place up to ten days or more after the trade date.
Normally the settlement date occurs within six months after the trade date;
however, the Fund may, from time to time, purchase securities whose settlement
date extends six months or more beyond 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 Fund maintains
internally designated assets with a market value equal to or greater than the
amount of its purchase commitments. The purchase of securities on a when-issued
basis or forward commitment may increase the volatility of the Fund's net asset
value to the extent the Fund executes such transactions while remaining
substantially fully invested. The Fund may also sell securities that it
purchased on a when-issued basis or forward commitment prior to settlement of
the original purchase. As of July 31, 2006, the Fund had purchased $27,803,819
of securities issued on a when-issued basis or forward commitment.

- --------------------------------------------------------------------------------
SECURITY CREDIT RISK. The Fund invests in high-yield securities, which may be
subject to a greater degree of credit risk, market fluctuations and loss of
income and principal, and may be more sensitive to economic conditions than
lower-yielding, higher-rated fixed-income securities. The Fund may acquire
securities in default, and is not obligated to dispose of securities whose
issuers subsequently default. As of July 31, 2006, securities with an aggregate
market value of $23,000, representing less than 0.01% of the Fund's net assets,
were in default.

      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.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated on a
daily basis to each class of shares based upon the relative proportion of net
assets represented by such class. Operating expenses directly attributable to a
specific class are charged against the operations of that class.

- --------------------------------------------------------------------------------
FEDERAL TAXES. The Fund 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 tax components of capital shown in the table below represent distribution
requirements the Fund must satisfy under the income tax regulations, losses the
Fund may be able to offset against income and gains realized in future years and
unrealized appreciation or depreciation of securities and other investments for
federal income tax purposes.

                                                                 NET UNREALIZED

1. As of July 31, 2006, the Fund had $789,546 of net capital loss carryforwards
available to offset future realized capital gains, if any, and thereby reduce
future taxable gain distributions. As of July 31, 2006, details of the capital
loss carryforward were as follows:

                              EXPIRING

2. As of July 31, 2006, the Fund had $2,411,711 of post-October losses available
to offset future realized capital gains, if any. Such losses, if unutilized,
will expire in 2015.

3. During the fiscal year ended July 31, 2006, the Fund utilized $2,383,733 of
capital loss carryforward to offset capital gains realized in that fiscal year.

4. During the fiscal year ended July 31, 2005, the Fund utilized $1,502,286 of
capital loss carryforward to offset capital gains realized in that fiscal year.

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 Fund. Accordingly, the
following amounts have been reclassified for July 31, 2006. Net assets of the
Fund were unaffected by the reclassifications.

The tax character of distributions paid during the years ended July 31, 2006 and
July 31, 2005 was as follows:

The aggregate cost of securities and other investments and the composition of
unrealized appreciation and depreciation of securities and other investments for
federal income tax purposes as of July 31, 2006 are noted below. The primary
difference between book and tax appreciation or depreciation of securities and
other investments, if applicable, is attributable to the tax deferral of losses
or tax realization of financial statement unrealized gain or loss.

TRUSTEES' COMPENSATION. THe Fund has adopted an unfunded retirement plan for the
Fund's independent trustees. Benefits are based on years of service and fees
paid to each trustee during the years of service. During the year ended July 31,
2006, the Fund's projected benefit obligations were increased by $18,222 and
payments of $8,353 were made to retired trustees, resulting in an accumulated
liability of $101,005 as of July 31, 2006.

      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 Fund.
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 Fund or in other Oppenheimer funds selected by the Trustee. The
Fund purchases shares of the funds selected for deferral by the Trustee in
amounts equal to his or her deemed investment, resulting in a Fund 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
Fund, and will not materially affect the Fund'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.

- --------------------------------------------------------------------------------
INVESTMENT INCOME. Interest income, which includes accretion of discount and
amortization of premium, is accrued as earned.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may
include interest expense incurred by the Fund 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 Fund pays
interest to its custodian on such cash overdrafts, to the extent they are not
offset by positive cash balances maintained by the Fund, 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 Fund
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 Fund'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 Fund. In the normal
course of business, the Fund may also enter into contracts that provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown as this would be dependent on future claims that may be made against the
Fund. The risk of material loss from such claims is considered remote.

- --------------------------------------------------------------------------------
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 Fund has authorized an unlimited number of $0.001 par value shares of
beneficial interest of each class. Transactions in shares of beneficial interest

DISTRIBUTION AND SERVICE PLANS FOR CLASS B AND CLASS C SHARES. The Fund has
adopted Distribution and Service Plans for Class B and Class C shares to
compensate the Distributor for its services in connection with the distribution
of those shares and servicing accounts. Under the plans, the Fund pays the
Distributor an annual asset-based sales charge of 0.75% on Class B and Class C
shares. The Distributor also receives a service fee of up to 0.25% under each
plan. If either the Class B or Class C plan is terminated by the Fund or by the
shareholders of a class, the Board of Trustees and its independent trustees must
determine whether the Distributor shall be entitled to payment from the Fund of
all or a portion of the service fee and/or asset-based sales charge in respect
to shares sold prior to the effective date of such termination. The
Distributor's aggregate uncompensated expenses under the plan at July 31, 2006
for Class B and Class C shares were $2,610,903 and $3,346,765, respectively.
Fees incurred by the Fund under the plans are detailed in the Statement of
Operations.

SALES CHARGES. Front-end sales charges and contingent deferred sales charges
(CDSC) do not represent expenses of the Fund. They are deducted from the
proceeds of sales of Fund shares prior to investment or from redemption proceeds
prior to remittance, as applicable. The sales charges retained by the
Distributor from the sale of shares and the CDSC retained by the Distributor on
the redemption of shares is shown in the following table for the period

5. ILLIQUID SECURITIES

As of July 31, 2006, investments in securities included issues that are
illiquid. A security may be considered illiquid if it lacks a readily available
market or if its valuation has not changed for a certain period of time. The
Fund will not invest more than 15% 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.

- --------------------------------------------------------------------------------
6. BORROWINGS

The Fund can borrow money from banks in amounts up to one-third of its total
assets (including the amount borrowed) less all liabilities and indebtedness
other than borrowings to purchase portfolio securities, to meet redemption
obligations or for temporary and emergency purposes. The purchase of securities
with borrowed funds creates leverage in the Fund.

      The Fund has entered into a Revolving Credit and Security Agreement (the
"Agreement") with a conduit lender and a bank which enables it to participate
with certain other Oppenheimer funds in a committed, secured borrowing facility
that permits borrowings of up to $900 million, collectively. To secure the loan,
the Fund pledges investment securities in accordance with the terms of the
Agreement. Interest is charged to the Fund, based on its borrowings, at current
commercial paper issuance rates (5.3126% as of July 31, 2006). The Fund pays
additional fees of 0.30% per annum on its outstanding borrowings to manage and
administer the facility and is allocated its pro-rata share of a 0.13% per annum
commitment fee for a liquidity backstop facility with respect to the $900
million facility size.

      For the year ended July 31, 2006, the average daily loan balance was
$36,349,041 at an average daily interest rate of 4.336%. The Fund had borrowings
outstanding of $20,300,000 at July 31, 2006 at an interest rate of 5.3126%. The
Fund had gross borrowings and gross loan repayments of $704,800,000 and
$752,100,000, respectively, during the year ended July 31, 2006. The maximum
amount of borrowings outstanding at any month-end during the year ended July 31,
2006 was $87,700,000. The Fund paid $153,837 in fees and $1,627,586 in interest
during the year ended July 31, 2006.

7. RECENT ACCOUNTING PRONOUNCEMENT

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48 ("FIN 48"), ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES.
FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an
enterprise's financial statements in accordance with FASB Statement No. 109,
Accounting for Income Taxes. FIN 48 requires the evaluation of tax positions
taken in the course of preparing the Fund's tax returns to determine whether it
is "more-likely-than-not" that tax positions taken in the Fund's tax return will
be ultimately sustained. A tax liability and expense must be recorded in respect
of any tax position that, in Management's judgment, will not be fully realized.
FIN 48 is

effective for fiscal years beginning after December 15, 2006. As of July 31,
2006, the Manager is evaluating the implications of FIN 48. Its impact in the
Fund's financial statements has not yet been determined.

- --------------------------------------------------------------------------------
8. LITIGATION

A consolidated amended complaint was filed as a putative class action against
the Manager and the Transfer Agent and other defendants (including 51 of the
Oppenheimer funds including the Fund) in the U.S. District Court for the
Southern District of New York on January 10, 2005 and was amended on March 4,
2005. The complaint alleged, among other things, that the Manager charged
excessive fees for distribution and other costs, and that by permitting and/or
participating in those actions, the Directors/Trustees and the Officers of the
funds breached their fiduciary duties to fund shareholders under the Investment
Company Act of 1940 and at common law. The plaintiffs sought unspecified
damages, an accounting of all fees paid, and an award of attorneys' fees and
litigation expenses.

      In response to the defendants' motions to dismiss the suit, seven of the
eight counts in the complaint, including the claims against certain of the
Oppenheimer funds, as nominal defendants, and against certain present and former
Directors, Trustees and Officers of the funds, and the Distributor, as
defendants, were dismissed with prejudice, by court order dated March 10, 2006,
and the remaining count against the Manager and the Transfer Agent was dismissed
with prejudice by court order dated April 5, 2006. The plaintiffs filed an
appeal of those dismissals on May 11, 2006.

      The Manager believes that the allegations contained in the complaint are
without merit and that there are substantial grounds to sustain the district
court's rulings. The Manager also believes that it is premature to render any
opinion as to the likelihood of an outcome unfavorable to it, the funds, the
Directors/Trustees or the Officers on the appeal of the decisions of the
district court, and that no estimate can yet be made with any degree of
certainty as to the amount or range of any potential loss.

- --------------------------------------------------------------------------------
THE BOARD OF TRUSTEES AND SHAREHOLDERS OF
OPPENHEIMER CALIFORNIA MUNICIPAL FUND:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer California Municipal Fund, including the statement of investments,
as of July 31, 2006, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the years in the
two-year period then ended, and the financial highlights for each of the years
in the five-year period then ended. These financial statements and financial
highlights are the responsibility of the Fund'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 July 31, 2006, by correspondence with the
custodian and brokers or by other appropriate auditing procedures where replies
from brokers were not received. 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
Oppenheimer California Municipal Fund as of July 31, 2006, the results of its
operations for the year then ended, the changes in its net assets for each of
the years in the two-year period then ended, and the financial highlights for
each of the years in the five-year period then ended, in conformity with U.S.
generally accepted accounting principles.

FEDERAL INCOME TAX INFORMATION  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
In early 2007, if applicable, shareholders of record will receive information
regarding all dividends and distributions paid to them by the Fund during
calendar year 2006. Regulations of the U.S. Treasury Department require the Fund
to report this information to the Internal Revenue Service.

      None of the dividends paid by the Fund during the fiscal year ended July
31, 2006 are eligible for the corporate dividend-received deduction. The
dividends were derived from interest on municipal bonds and are not subject to
federal income taxes. To the extent a shareholder is subject to any state or
local tax laws, some or all of the dividends received may be taxable.

      The foregoing information is presented to assist shareholders in reporting
distributions received from the Fund 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 2. CODE OF ETHICS.

The registrant has adopted a code of ethics that applies to the registrant's
principal executive officer, principal financial officer, principal accounting
officer or controller or persons performing similar functions.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The Board of Trustees of the registrant has determined that the registrant does
not have an audit committee financial expert serving on its Audit Committee. In
this regard, no member of the Audit Committee was identified as having all of
the technical attributes identified in Instruction 2(b) to Item 3 of Form N-CSR
to qualify as an "audit committee



financial expert," whether through the type of specialized education or
experience described in that Instruction. The Board has concluded that while the
members of the Audit Committee collectively have the necessary attributes and
experience required to serve effectively as an Audit Committee, no single member
possesses all of the required technical attributes through the particular
methods of education or experience set forth in the Instructions to be
designated as an audit committee financial expert.

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 07/31/2006, 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.
