Discussion of Fund performance

By MFC Global Investment Management (U.S.), LLC

Municipal bonds weathered a difficult environment to post positive results for the year ended August 31, 2008. Mortgage-related losses led to credit rating downgrades for municipal bond insurers. The ensuing credit concerns, along with an exodus of non-traditional municipal investors such as hedge funds, led to a sell-off in the municipal market in early 2008. However, municipal bonds enjoyed a recovery during the last six months of the period. California has been hit particularly hard by the U.S. economic slowdown, leading to a sizable budget deficit. The state is currently operating without a budget as the governor and legislature struggle to resolve the deficit problem.

Fund performance

For the year ended August 31, 2008, John Hancock California Tax-Free Income Fund’s Class A, Class B and Class C shares posted total returns of 2.18%, 1.31% and 1.31%, respectively, at net asset value. By comparison, Morningstar’s muni California long fund category produced an average return of 1.33%, while the Lehman Brothers Municipal Bond Index returned 4.48%.

“Municipal bonds weathered a
difficult environment to post
positive results for the year ended
August 31, 2008.”

The key behind the Fund’s outperformance of its Morningstar peer group average was its higher credit quality. With credit spreads — the difference between the yields of higher-and lower-quality bonds — widening significantly during the period, the portfolio’s emphasis on higher-quality securities enhanced results relative to its peer group. Another favorable factor was individual security selection, particularly among lower-quality bonds. Our focus on fundamental credit research and comprehensive analysis was rewarded as our lower-quality holdings held up well in a difficult environment for lower-rated investments.

Bonds that finance essential services, such as water and sewer, were among the better performers in the portfolio for the 12-month period, along with education and general obligation bonds. The weakest performers were tobacco bonds, which suffered the most from the hedge-fund selling.

This commentary reflects the views of the portfolio managers through the end of the Fund’s period discussed in this report. The managers’ statements reflect their own opinions. As such, they are in no way guarantees of future events and are not intended to be used as investment advice or a recommendation regarding any specific security. They are also subject to change at any time as market and other conditions warrant.

Past performance is no guarantee of future results.

Sector investing is subject to greater risks than the market as a whole. Because the Fund may focus on particular sectors of the economy, its performance may depend on the performance of those sectors.

C	4-1-99	0.33	3.25	—	3.16	0.33	17.34	—	34.06	4.12

Performance figures assume all distributions are reinvested. Public offering price (POP) figures reflect maximum sales charges on Class A shares of 4.5% and the applicable contingent deferred sales charge (CDSC) on Class B and Class C shares. The returns for Class C shares have been adjusted to reflect the elimination of the front-end sales charge effective July 15, 2004. The Class B shares’ CDSC declines annually between years 1 to 6 according to the following schedule: 5, 4, 3, 3, 2, 1%. No sales charge will be assessed after the sixth year. Class C shares held for less than one year are subject to a 1% CDSC.

The expense ratios of the Fund, both net (including any fee waivers or expense limitations) and gross (excluding any fee waivers or expense limitations), are set forth according to the most recent publicly available prospectus for the Fund and may differ from the expense ratios disclosed in the Financial Highlights tables in this report. The net expenses equal the gross expenses and are as follows: Class A — 0.81%, Class B — 1.66%, Class C — 1.66%.

The returns reflect past results and should not be considered indicative of future performance. The return and principal value of an investment will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Due to market volatility, the Fund’s current performance may be higher or lower than the performance shown. For current to the most recent month end performance data, please call 1-800-225-5291 or visit the Fund’s Web site at www.jhfunds.com.

The performance table above and the chart on the next page do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Please note that a portion of the Fund’s income may be subject to taxes, and some investors may be subject to the Alternative Minimum Tax (AMT). Also note that capital gains are taxable.

The Fund’s performance results reflect any applicable expense reductions, without which the expenses would increase and results would have been less favorable.

A look at performance

Growth of $10,000

This chart shows what happened to a hypothetical $10,000 investment in California Tax-Free Income Fund Class A shares for the period indicated. For comparison, we’ve shown the same investment in the Lehman Brothers Municipal Bond Index.

			With maximum
Class	Period beginning	Without sales charge	sales charge	Index
B2	8-31-98	$13,968	$13,968	$16,094
C2	4-1-99	13,406	13,406	15,662

Assuming all distributions were reinvested for the period indicated, the table above shows the value of a $10,000 investment in the Fund’s Class B and Class C shares, respectively, as of August 31, 2008. The Class C shares investment with maximum sales charge has been adjusted to reflect the elimination of the front-end sales charge effective July 15, 2004. Performance of the classes will vary based on the difference in sales charges paid by shareholders investing in the different classes and the fee structure of those classes.

Lehman Brothers Municipal Bond Index is an unmanaged index that includes municipal bonds and is commonly used as a measure of bond performance.

It is not possible to invest directly in an index. Index figures do not reflect sales charges, which would have resulted in lower values if they did.

¹ NAV represents net asset value and POP represents public offering price.

² No contingent deferred sales charge applicable.

Your expenses

These examples are intended to help you understand your ongoing operating expenses.

Understanding fund expenses

As a shareholder of the Fund, you incur two types of costs:

■ Transaction costs which include sales charges (loads) on purchases or redemptions (varies by share class), minimum account fee charge, etc.

■ Ongoing operating expenses including management fees, distribution and service fees (if applicable), and other fund expenses.

We are going to present only your ongoing operating expenses here.

Actual expenses/actual returns

This example is intended to provide information about your fund’s actual ongoing operating expenses, and is based on your fund’s actual return. It assumes an account value of $1,000.00 on March 1, 2008 with the same investment held until August 31, 2008.

	Account value	Ending value	Expenses paid during
	on 3-1-08	on 8-31-08	period ended 8-31-081
Class A	$1,000.00	$1,052.20	$4.23
Class B	1,000.00	$1,047.70	8.60
Class C	1,000.00	$1,047.70	8.60

Together with the value of your account, you may use this information to estimate the operating expenses that you paid over the period. Simply divide your account value at August 31, 2008, by $1,000.00, then multiply it by the “expenses paid” for your share class from the table above. For example, for an account value of $8,600.00, the operating expenses should be calculated as follows:

Your expenses

Hypothetical example for comparison purposes

This table allows you to compare your fund’s ongoing operating expenses with those of any other fund. It provides an example of the Fund’s hypothetical account values and hypothetical expenses based on each class’s actual expense ratio and an assumed 5% annualized return before expenses (which is not your fund’s actual return). It assumes an account value of $1,000.00 on March 1, 2008, with the same investment held until August 31, 2008. Look in any other fund shareholder report to find its hypothetical example and you will be able to compare these expenses.

	Account value	Ending value	Expenses paid during
	on 3-1-08	on 8-31-08	period ended 8-31-081
Class A	$1,000.00	$1,021.00	$4.17
Class B	1,000.00	1,016.70	8.47
Class C	1,000.00	1,016.70	8.47

Remember, these examples do not include any transaction costs, such as sales charges; therefore, these examples will not help you to determine the relative total costs of owning different funds. If transaction costs were included, your expenses would have been higher. See the prospectus for details regarding transaction costs.

¹ Expenses are equal to the Fund’s annualized expense ratio of 0.82%, 1.67% and 1.67% for Class A, Class B and Class C, respectively, multiplied by the average account value over the period, multiplied by number of days in most recent fiscal half-year/366 (to reflect the one-half year period).

Notes to financial statements

Note 1
Organization

John Hancock California Tax-Free Income Fund (the Fund) is a non-diversified open-end management investment company registered under the Investment Company Act of 1940, as amended (the 1940 Act). The Fund seeks a high level of current income, consistent with the preservation of capital, that is exempt from federal and California personal income taxes. Since the Fund invests primarily in California issuers, the Fund may be affected by political, economic or regulatory developments in the state of California.

The Trustees have authorized the issuance of multiple classes of shares of the Fund, designated as Class A, Class B and Class C shares. The shares of each class represent an interest in the same portfolio of investments of the Fund and have equal rights as to voting, redemptions, dividends and liquidation, except that certain expenses, subject to the approval of the Trustees, may be applied differently to each class of shares in accordance with current regulations of the Securities and Exchange Commission (SEC) and the Internal Revenue Service. Shareholders of a class that bears distribution and service expenses under the terms of a distribution plan have exclusive voting rights to that distribution plan. Class B shares will convert to Class A shares eight years after purchase.

Note 2
Significant accounting policies

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. The following summarizes the significant accounting policies of the Fund:

Security valuation

The net asset value of Class A, Class B and Class C shares of the Fund is determined daily as of the close of the New York Stock Exchange (NYSE), normally at 4:00 p.m., Eastern Time. Short-term debt investments that have a remaining maturity of 60 days or less are valued at amortized cost, and thereafter assume a constant amortization to maturity of any discount or premium, which approximates market value. All other securities held by the Fund are valued at the last sale price or official closing price (closing bid price or last evaluated quote if no sale has occurred) as of the close of business on the principal securities exchange (domestic or foreign) on which they trade or, lacking any sales, at the closing bid price. Securities traded only in the over-the-counter market are valued at the last bid price quoted by b rokers making markets in the securities at the close of trading. Securities for which there are no such quotations, principally debt securities, are valued based on the evaluated prices provided by an independent pricing service, which utilizes both dealer-supplied and electronic data processing techniques, which take into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data. Fixed income securities are subject to credit and interest rate risk and involve some risk of default in connection with principal and interest payments.

Other assets and securities for which no such quotations are readily available are valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees.

26  California Tax-Free Income Fund | Annual report 

Valuations change in response to many factors including the historical and prospective earnings of the issuer, the value of the issuer’s assets, general economic conditions, interest rates, investor perceptions and market liquidity.

Joint repurchase agreement

Pursuant to an exemptive order issued by the SEC, the Fund, along with other registered investment companies having a management contract with John Hancock Advisers, LLC (the Adviser), a wholly owned subsidiary of John Hancock Financial Services, Inc., a subsidiary of Manulife Financial Corporation (MFC), may participate in a joint repurchase agreement transaction. Aggregate cash balances are invested in one or more large repurchase agreements, whose underlying securities are obligations of the U.S. government and/or its agencies. The Fund’s custodian bank receives delivery of the underlying securities for the joint account on the Fund’s behalf. When a Fund enters into a repurchase agreement, it receives delivery of collateral, the amount of which at the time of purchase and each subsequent business day is required to be maintained at such a level that the value is generally 102% of the repurchase amount.

Investment transactions

Investment transactions are accounted for on a trade date plus one basis for daily net asset value calculations. However, for financial reporting purposes, investment security transactions are reported on trade date. Interest income is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date net of foreign withholding taxes. Discounts/premiums are accreted/amortized for financial reporting purposes. Realized gains and losses from investment transactions are recorded on an identified cost basis.

Class allocations

Income, common expenses and realized and unrealized gains (losses) are determined at the fund level and allocated daily to each class of shares based on the appropriate net asset value of the respective classes. Distribution and service fees, if any, and transer agent fees for Class A, Class B and Class C shares are calculated daily at the class level based on the appropriate net asset value of each class and the specific expense rate(s) applicable to each class.

Guarantees and indemnifications

Under the Fund’s organizational documents, its Officers and Trustees are indemnified against certain liability arising out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred.

Expenses

The majority of expenses are directly identifiable to an individual fund. Trust expenses that are not readily identifiable to a specific fund are allocated in such a manner as deemed equitable, taking into consideration, among other things, the nature and type of expense and the relative size of the funds.

Bank borrowings

The Fund is permitted to have bank borrowings for temporary or emergency purposes, including the meeting of redemption requests that otherwise might require the untimely disposition of securities. The Fund has entered into a line of credit agreement with The Bank of New York Mellon (BNYM), the Swing Line Lender and Administrative Agent. This agreement enables the Fund to participate, with other funds managed by the Adviser, in an unsecured line of credit with BNYM, which permits borrowings of up to $150 million, collectively. Interest is charged to each fund based on its borrowing. In addition, a commitment fee is charged to each fund based on the average daily unused portion of the line of credit and is allocated among the participating funds. The Fund had no borrowing activity under the line of credit during the year ended August 31, 2008.

Pursuant to the custodian agreement, the Custodian may, in its discretion, advance funds to the Fund to make properly authorized payments. When such payments result in an overdraft, the Fund is obligated to repay the Custodian for any overdraft together with interest due thereon. The Custodian has a lien, security interest or security

Annual report | California Tax-Free Income Fund  27 

entitlement in any Fund property, to the maximum extent permitted by law to the extent of any overdraft.

Federal income taxes

The Fund qualifies as a regulated investment company by complying with the applicable provisions of the Internal Revenue Code and will not be subject to federal income tax on taxable income that is distributed to shareholders. Therefore, no federal income tax provision is required.

The Fund has adopted the provisions of Financial Accounting Standards Board (FASB) Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement 109 (FIN 48), at the beginning of the Fund’s fiscal year. FIN 48 prescribes a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. The implementation of FIN 48 did not have a material impact on the Fund’s financial statements. Each of the Fund’s federal tax returns for the prior three years remain subject to examination by the Internal Revenue Service.

New accounting pronouncements

In September 2006, FASB Standard No. 157, Fair Value Measurements (FAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosure about fair value measurements. As of July 31, 2008, management does not believe the adoption of FAS 157 will have a material impact on the amounts reported in the financial statements.

In March 2008, FASB No. 161 (FAS 161), Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133 (FAS 133), was issued and is effective for fiscal years and interim reporting periods beginning after November 15, 2008. FAS 161 amends and expands the disclosure requirements of FAS 133 in order to provide financial statement users an understanding of a company’s use of derivative instruments, how derivative instruments are accounted for under FAS 133 and related interpretations and how these instruments affect a company’s financial position, performance, and cash flows. FAS 161 requires companies to disclose information detailing the objectives and strategies for using derivative instruments, the level of derivative activity entered into by the company, and any credit risk-related contingent features of the agreements. M anagement is currently evaluating the adoption of FAS 161 on the Fund’s financial statement disclosures.

Distribution of income and gains

The Fund records distributions to shareholders from net investment income and net realized gains, if any, on the ex-dividend date. The Fund generally declares dividends daily and pays them monthly. Capital gains, if any, are distributed annually. During the year ended August 31, 2007, the tax character of distributions paid was as follows: ordinary income $48,591 and exempt income $13,998,255. During the year ended August 31, 2008, the tax character of distributions paid was as follows: ordinary income $20,361, exempt income $14,082,238, and long-term capital gains $405,825. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner, at the same time and are in the same amount, except for the effect of expenses that may be applied differently to each class.

As of August 31, 2008, the components of distributable earnings on a tax basis included $60,375 of undistributed exempt income and $183,171 of undistributed long-term gain.

Such distributions and distributable earnings, on a tax basis, are determined in conformity with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. Distributions in excess of tax basis earnings and profits, if any, are reported in the Fund’s financial statements as a return of capital.

Capital accounts within financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period. Permanent book-tax differences are primarily

28  California Tax-Free Income Fund | Annual report 

attributable to amortization and accretion on debt securities.

Note 3
Risks and uncertainties

State concentration risk

The Fund invests mainly in bonds from a single state and its performance is affected by local, state and regional factors. The risks may include economic or policy changes, erosion of the tax base, and state legislative changes (especially those regarding budgeting and taxes). Although the Fund invests mainly in investment-grade bonds, which generally have a relatively low level of credit risk, any factors that might lead to a credit decline statewide would be likely to cause widespread decline in the credit quality of the Fund’s holdings.

Insurance concentration risk

The Fund may hold insured municipal obligations which are insured as to their scheduled payment of principal and interest under an insurance policy obtained by the issuer or underwriter of the obligation at the time of its original issuance. Since there are a limited number of municipal obligation insurers, a Fund may have a concentration of investments covered by one insurer. Accordingly, the concentration may make the Fund’s value more volatile and investment values may rise and fall more rapidly. In addition, the credit quality of companies which provide the insurance may affect the value of those securities and insurance does not guarantee the market value of the insured obligation.

Municipal bond risk

The Fund generally invests in general obligation or revenue municipal bonds. The bonds are backed by the municipal issuer and have the risk that the issuer’s credit quality will decline. General obligation bonds are backed by the municipal issuer’s ability to levy taxes. In extreme cases, a municipal issuer could declare bankruptcy or otherwise become unable to honor its commitments to bondholders which may be caused by many reasons, including fiscal mismanagement and erosion of the tax base. Revenue bonds are backed only by income associated with a specific facility. Any circumstance that reduces or threatens the economic viability of that particular facility can affect the bond’s credit quality.

Note 4
Management fee and transactions with
affiliates and others

The Fund has an investment management contract with the Adviser. Under the investment management contract, the Fund pays a monthly management fee to the Adviser equivalent, on an annual basis, to the sum of: (a) 0.55% of the first $500,000,000 of the Fund’s average daily net asset value and (b) 0.50% of the Fund’s average daily net asset value in excess of $500,000,000. The effective rate for the year ended August 31, 2008 is 0.55% of the Fund’s average daily net asset value. The Fund has a subadvisory agreement with MFC Global Investment Management (U.S.), LLC, a subsidiary of John Hancock Financial Services, Inc. The Fund is not responsible for payment of subadvisory fees.

The Fund has a Distribution Agreement with John Hancock Funds, LLC (JH Funds), a wholly owned subsidiary of the Adviser. The Fund has adopted Distribution Plans with respect to Class A, Class B and Class C, pursuant to Rule 12b-1 under the 1940 Act, to pay JH Funds for the services it provides as distributor of shares of the Fund. Accordingly, the Fund makes monthly payments to JH Funds at an annual rate not to exceed 0.15%, 1.00% and 1.00% of average daily net asset value of Class A, Class B and Class C, respectively. A maximum of 0.25% of such payments may be service fees, as defined by the Conduct Rules of the Financial Industry Regulatory Authority (formerly the National Association of Securities Dealers). Under the Conduct Rules, curtailment of a portion of the Fund’s 12b-1 payments could occur under certain circumstances.

The Fund has an agreement with its custodian bank, under which custody fees are reduced by balance credits applied during the period. Accordingly, the expense reductions related to custody fee offsets amounted to $116.

Class A shares are assessed up-front sales charges. During the year ended August 31, 2008, JH Funds received net up-front sales charges

Annual report | California Tax-Free Income Fund  29 

of $258,776 with regard to sales of Class A shares. Of this amount, $30,701 was retained and used for printing prospectuses, advertising, sales literature and other purposes, $219,826 was paid as sales commissions to unrelated broker-dealers and $5,249 was paid as sales commissions to sales personnel of Signator Investors, Inc. (Signator Investors), a related broker-dealer. The Adviser’s indirect parent, John Hancock Life Insurance Company (JHLICO), is the indirect sole shareholder of Signator Investors.

Class B shares that are redeemed within six years of purchase are subject to a contingent deferred sales charge (CDSC) at declining rates, beginning at 5.00% of the lesser of the current market value at the time of redemption or the original purchase cost of the shares being redeemed. Class C shares that are redeemed within one year of purchase are subject to a CDSC at a rate of 1.00% of the lesser of the current market value at the time of redemption or the original purchase cost of the shares being redeemed. Proceeds from the CDSCs are paid to JH Funds and are used in whole or in part to defray its expenses for providing distribution-related services to the Fund in connection with the sale of Class B and Class C shares. During the year ended August 31, 2008, CDSCs received by JH Funds amounted to $7,584 for Class B shares and $1,327 for Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature Services, Inc. (Signature Services), an indirect subsidiary of JHLICO. For Class A, Class B and Class C shares, the Fund pays a monthly transfer agent fee at an annual rate of 0.01% of each class’s average daily net asset value, plus a fee based on the number of shareholder accounts and reimbursement for certain out-of-pocket expenses, aggregated and allocated to each class on the basis of its relative net asset value. For the period from September 1, 2007 to May 31, 2008, the Fund paid a monthly fee which is based on an annual rate of $16 for each Class A shareholder account, $18.50 for each Class B shareholder account and $17.50 for each Class C shareholder account. Effective June 1, 2008, the Fund pays a monthly fee which is based on an annual rate of $17.50 for each Class A, Class B and Class C shareholder account.

The Fund receives earnings credits from its transfer agent as a result of uninvested cash balances. These credits are used to reduce a portion of the Fund’s transfer agent fees and out-of-pocket expenses. During the year ended August 31, 2008, the Fund’s transfer agent fees and out-of-pocket expenses were reduced by $1,872 for transfer agent credits earned.

Class level expenses for the year ended August 31, 2008 were as follows:

	Distribution and
Share class	service fees
Class A	$451,009
Class B	123,691
Class C	125,027
Total	$699,727

The Fund has an agreement with the Adviser and affiliates to perform necessary tax, accounting, compliance, legal and other administrative services for the Fund. The compensation for the year amounted to $37,228 with an effective rate of 0.01% of the Fund’s average daily net asset value.

Mr. James R. Boyle is Chairman of the Adviser, as well as affiliated Trustee of the Fund, and is compensated by the Adviser and/or its affiliates. The compensation of unaffiliated Trustees is borne by the Fund. The unaffiliated Trustees may elect to defer, for tax purposes, their receipt of this compensation under the John Hancock Group of Funds Deferred Compensation Plan. The Fund makes investments into other John Hancock funds, as applicable, to cover its liability for the deferred compensation. Investments to cover the Fund’s deferred compensation liability are recorded on the Fund’s books as an other asset. The deferred compensation liability and the related other asset are always equal and are marked to market on a periodic basis to reflect any income earned by the investments, as well as any unrealized gains or losses. The Deferred Compensation Plan investments had no impact on the operations of the Fund.

Auditors’ report

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of John Hancock California Tax-Free Income Fund,

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of John Hancock California Tax-Free Income Fund (the Fund) at August 31, 2008, and the results of its operations, the changes in its net assets and the financial highlights for the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at August 31, 2008 by correspondence with the custodian and brokers, and the application of alternative auditing procedures where securities purchased had not been received, provide a reasonable basis for our opinion. The financial highlights for each of the periods ended on or before August 31, 2005 were audited by other auditors whose report expressed an unqualified opinion thereon.

Board Consideration of and
Continuation of Investment Advisory
Agreement and Subadvisory
Agreement: John Hancock California
Tax-Free Income Fund

The Investment Company Act of 1940 (the 1940 Act) requires the Board of Trustees (the Board) of John Hancock Tax-Exempt Series Fund (the Trust), including a majority of the Trustees who have no direct or indirect interest in the investment advisory agreement and are not “interested persons” of the Trust, as defined in the 1940 Act (the Independent Trustees), annually to meet in person to review and consider the continuation of: (i) the investment advisory agreement (the Advisory Agreement) with John Hancock Advisers, LLC (the Adviser) and (ii) the investment subadvisory agreement (the Subadvisory Agreement) with MFC Global Investment Management (U.S.), LLC (the Subadviser) for the John Hancock California Tax-Free Income Fund (the Fund). The Advisory Agreement and the Subadvisory Agreement are collectively referred to as the Advisory Agreements.

At meetings held on May 5–6 and June 9–10, 2008, the Board considered the factors and reached the conclusions described below relating to the selection of the Adviser and Subadviser and the continuation of the Advisory Agreements. During such meetings, the Board’s Contracts/Operations Committee and the Independent Trustees also met in executive sessions with their independent legal counsel.

In evaluating the Advisory Agreements, the Board, including the Contracts/Operations Committee and its Independent Trustees, reviewed a broad range of information requested for this purpose. This information included: (i) the investment performance of the Fund relative to a category of relevant funds (the Category) and a peer group of comparable funds (the Peer Group). The funds within each Category and Peer Group were selected by Morningstar Inc. (Morningstar), an independent provider of investment company data. Data covered a range of periods ended December 31, 2007, (ii) advisory and other fees incurred by, and the expense ratios of, the Fund relative to a Category and a Peer Group, (iii) the advisory fees of comparable portfolios of other clients of the Adviser and the Subadviser, (iv) the Adviser’s financial results and condition, including its and certain of its affiliates’ profitability from services performed for the Fund, (v) breakpoints in the Fund’s and the Peer Group’s fees, and information about economies of scale, (vi) the Adviser’s and Subadviser’s record of compliance with applicable laws and regulations, with the Fund’s investment policies and restrictions, and with the applicable Code of Ethics, and the structure and responsibilities of the Adviser’s and Subadviser’s compliance department, (vii) the background and experience of senior management and investment professionals, and (viii) the nature, cost and character of advisory and non-investment management services provided by the Adviser and its affiliates and by the Subadviser.

The Independent Trustees considered the legal advice of independent legal counsel and relied on their own business judgment in determining the factors to be considered in evaluating the materials that were presented to them and the weight to be given to each such factor. The Board’s review and conclusions were based on a comprehensive consideration of all information presented to the Board and not the result of any single controlling factor. The Board principally considered data on performance and other information provided by Morningstar as of December 31, 2007. The Board also considered updated performance information provided to it by the Adviser or Subadviser at its May and June 2008 meetings. Performance and other information may be quite different as of the date of this shareholders report. The key factors considered by the Board and the conclusions reached are described below.

Nature, extent and quality of services

The Board considered the ability of the Adviser and the Subadviser, based on their resources, reputation and other attributes, to attract and retain qualified investment professionals, including research, advisory, and supervisory personnel. The Board considered the investment philosophy, research and

34  California Tax-Free Income Fund | Annual report 

investment decision-making processes of the Adviser and Subadviser. The Board considered the Adviser’s execution of its oversight responsibilities. The Board further considered the culture of compliance, resources dedicated to compliance, compliance programs and compliance records of the Adviser and Subadviser. In addition, the Board took into account the administrative and other non-advisory services provided to the Fund by the Adviser and its affiliates.

Based on the above factors, together with those referenced below, the Board concluded that, within the context of its full deliberations, the nature, extent and quality of the investment advisory services provided to the Fund by the Adviser and Subadviser supported renewal of the Advisory Agreements.

Fund performance

The Board considered the performance results for the Fund over various time periods ended December 31, 2007. The Board also considered these results in comparison to the performance of the Category, as well as the Fund’s Peer Group and benchmark index. The Board reviewed with representatives of Morningstar the methodology used by Morningstar to select the funds in the Category and the Peer Group.

The Board noted that the Fund’s performance for the 1-year period was lower than the performance of the median of the Category and its benchmark index, the Lehman Brothers Municipal Bond Index. The Board also noted that the Fund’s performance was generally in line with the median performance of the Category for the 3-, 5- and 10-year periods. The Board viewed favorably that the Fund’s performance was generally in line with the performance of the Peer Group median for the 5-year period and was higher than the performance of the Peer Group median for the 1-, 3- and 5-year periods.

Investment advisory fee and subadvisory
fee rates and expenses

The Board reviewed and considered the contractual investment advisory fee rate payable by the Fund to the Adviser for investment advisory services (the Advisory Agreement Rate). The Board received and considered information comparing the Advisory Agreement Rate with the advisory fees for the Peer Group and Category. The Board noted that the Advisory Agreement Rate was higher than the Peer Group median and not appreciably higher than the Category median.

The Board received and considered expense information regarding the Fund’s various components, including advisory fees, distribution and fees other than advisory and distribution fees, including transfer agent fees, custodian fees, and other miscellaneous fees (e.g., fees for accounting and legal services). The Board considered comparisons of these expenses to the Peer Group median. The Board also received and considered expense information regarding the Fund’s total operating expense ratio (Expense Ratio). The Board received and considered information comparing the Expense Ratio of the Fund to that of the Peer Group and Category medians before the application of fee waivers and reimbursements (Gross Expense Ratio) and after the application of such waivers and reimbursement (Net Expense Ratio). The Board also noted the differences in the funds included in the Peer Group and Category, including differences in the employment of fee waivers. The Board noted that the Fund’s Gross Expense Ratio was lower than the Peer Group and Category medians. The Board also noted that the Fund’s Net Expense Ratio was lower than the Peer Group median and equal to the Category median.

The Adviser also discussed the Morningstar data and rankings, and other relevant information, for the Fund. Based on the above-referenced considerations and other factors, the Board concluded that the Fund’s overall expenses results and performance supported the re-approval of the Advisory Agreements.

The Board also received information about the investment subadvisory fee rate (the Subadvisory Agreement Rate) payable by the Adviser to the Subadviser for investment subadvisory services. The Board concluded that the Subadvisory Agreement Rate was fair and equitable, based on its consideration of the factors described here.

Annual report | California Tax-Free Income Fund  35 

Profitability

The Board received and considered a detailed profitability analysis of the Adviser based on the Advisory Agreements, as well as on other relationships between the Fund and the Adviser and its affiliates, including the Subadviser. The Board also considered a comparison of the Adviser’s profitability to that of other similar investment advisers whose profitability information is publicly available. The Board concluded that, in light of the costs of providing investment management and other services to the Fund, the profits and other ancillary benefits reported by the Adviser were not unreasonable.

Economies of scale

The Board received and considered general information regarding economies of scale with respect to the management of the Fund, including the Fund’s ability to appropriately benefit from economies of scale under the Fund’s fee structure. The Board recognized the inherent limitations of any analysis of economies of scale, stemming largely from the Board’s understanding that most of the Adviser’s costs are not specific to individual Funds, but rather are incurred across a variety of products and services.

To the extent the Board and the Adviser were able to identify actual or potential economies of scale from Fund-specific or allocated expenses, in order to ensure that any such economies continue to be reasonably shared with the Fund as its assets increase, the Adviser and the Board agreed to continue the existing breakpoints to the Advisory Agreement Rate.

Information about services to other clients

The Board also received information about the nature, extent and quality of services and fee rates offered by the Adviser and Subadviser to their other clients, including other registered investment companies, institutional investors and separate accounts. The Board concluded that the Advisory Agreement Rate and the Subadvisory Agreement Rate were not unreasonable, taking into account fee rates offered to others by the Adviser and Subadviser, respectively, after giving effect to differences in services.

Other benefits to the Adviser

The Board received information regarding potential “fall-out” or ancillary benefits received by the Adviser and its affiliates, including the Subadvisor, as a result of their relationship with the Fund. Such benefits could include, among others, benefits directly attributable to the relationship of the Adviser and Subadviser with the Fund and benefits potentially derived from an increase in business as a result of their relationship with the Fund (such as the ability to market to shareholders other financial products offered by the Adviser and its affiliates).

The Board also considered the effectiveness of the Adviser’s, Subadviser’s and Fund’s policies and procedures for complying with the requirements of the federal securities laws, including those relating to best execution of portfolio transactions and brokerage allocation.

Other factors and broader review

As discussed above, the Board reviewed detailed materials received from the Adviser and Subadviser as part of the annual re-approval process. The Board also regularly reviews and assesses the quality of the services that the Fund receives throughout the year. In this regard, the Board reviews reports of the Adviser at least quarterly, which include, among other things, fund performance reports and compliance reports. In addition, the Board meets with portfolio managers and senior investment officers at various times throughout the year.

After considering the above-described factors and based on its deliberations and its evaluation of the information described above, the Board concluded that approval of the continuation of the Advisory Agreements for the Fund was in the best interest of the Fund and its shareholders. Accordingly, the Board unanimously approved the continuation of the Advisory Agreements.

ITEM 2. CODE OF ETHICS.

As of the end of the period, August 31, 2008, the registrant has adopted a code of ethics, as defined in Item 2 of Form N-CSR, that applies to its Chief Executive Officer, Chief Financial Officer and Treasurer (respectively, the principal executive officer, the principal financial officer and the principal accounting officer, the “Senior Financial Officers”). A copy of the code of ethics is filed as an exhibit to this Form N-CSR.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

Charles L. Ladner is the audit committee financial expert and is “independent”, pursuant to general instructions on Form N-CSR Item 3.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

(a) Audit Fees

The aggregate fees billed for professional services rendered by the principal accountant(s) for the audit of the registrant’s annual financial statements or services that are normally provided by the accountant(s) in connection with statutory and regulatory filings or engagements amounted to $26,850 for the fiscal year ended August 31, 2008 and $26,850 for the fiscal year ended August 31, 2007. These fees were billed to the registrant and were approved by the registrant’s audit committee.

(b) Audit-Related Services

There were no audit-related fees during the fiscal year ended August 31, 2008 and fiscal year ended August 31, 2007 billed to the registrant or to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant ("control affiliates").

(c) Tax Fees

The aggregate fees billed for professional services rendered by the principal accountant(s) for the tax compliance, tax advice and tax planning (“tax fees”) amounted to $3,400 for the fiscal year ended August 31, 2008 and $3,400 for the fiscal year ended August 31, 2007. The nature of the services comprising the tax fees was the review of the registrant’s income tax returns and tax distribution requirements. These fees were billed to the registrant and were approved by the registrant’s audit committee. There were no tax fees billed to the control affiliates.

(d) All Other Fees

There were no other fees during the fiscal year ended August 31, 2008 and fiscal year ended August 31, 2007 billed to the registrant or to the control affiliates.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:

The trust’s Audit Committee must pre-approve all audit and non-audit services provided by the independent registered public accounting firm (the “Auditor”) relating to the operations or financial

reporting of the funds. Prior to the commencement of any audit or non-audit services to a fund, the Audit Committee reviews the services to determine whether they are appropriate and permissible under applicable law.

The trust’s Audit Committee has adopted policies and procedures to, among other purposes, provide a framework for the Committee’s consideration of audit-related and non-audit services by the Auditor. The policies and procedures require that any audit-related and non-audit service provided by the Auditor and any non-audit service provided by the Auditor to a fund service provider that relates directly to the operations and financial reporting of a fund are subject to approval by the Audit Committee before such service is provided. Audit-related services provided by the Auditor that are expected to exceed $25,000 per instance/per fund are subject to specific pre-approval by the Audit Committee. Tax services provided by the Auditor that are expected to exceed $30,000 per instance/per fund are subject to specific pre-approval by the Audit Committee.

All audit services, as well as the audit-related and non-audit services that are expected to exceed the amounts stated above, must be approved in advance of provision of the service by formal resolution of the Audit Committee. At the regularly scheduled Audit Committee meetings, the Committee reviews a report summarizing the services, including fees, provided by the Auditor.

(e)(2) Services approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X:

Audit-Related Fees, Tax Fees and All Other Fees:

There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception under Rule 2-01 of Regulation S-X.

(f) According to the registrant’s principal accountant, for the fiscal year ended August 31, 2008, the percentage of hours spent on the audit of the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons who were not full-time, permanent employees of principal accountant was less than 50%.

(g) The aggregate non-audit fees billed by the registrant's accountant(s) for services rendered to the registrant and rendered to the registrant's control affiliates for each of the last two fiscal years of the registrant were $865,845 for the fiscal year ended August 31, 2008, and $1,684,235 for the fiscal year ended August 31, 2007.

(h) The audit committee of the registrant has considered the non-audit services provided by the registrant’s principal accountant(s) to the control affiliates and has determined that the services that were not pre-approved are compatible with maintaining the principal accountant(s)' independence.

Each of the Registrant’s Executive Officers should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

II. Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest Overview

A “conflict of interest” occurs when an Executive Officer’s private interest interferes with the interests of, or his service to, the Fund. For example, a conflict of interest would arise if a Registrant’s Executive Officers, or a member of his family, receives improper personal benefits as a result of his position with the Fund. Certain conflicts of interest arise out of the relationships between the Executive Officers and the Fund and already are subject to conflict of interest provisions in the Investment Company Act of 1940, as amended (the “Investment Company Act”) and the Investment Advisers Act of 1940, as amended (the “Investment Advisers Act”). For example, Executive Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Fund because of their status as “affiliated persons” of the Fund. Each of the Registrant’s Executive Officers is a n officer or employee of the investment adviser or a service provider (“Service Provider”) to the Fund. The Fund’s, the investment adviser’s and the Service Provider’s compliance programs and procedures are designed to prevent, or identify and correct, violations of these provisions. This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside of the parameters of this Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between the Fund and the investment adviser and the Service Provider of which the Executive Officers are also officers or employees. As a result, this Code recognizes that the Registrant’s Executive Officers will, in the normal course of their duties (whether formally for the Fund, for the investment adviser or for the Service Provider), be involved in establishing policies and implementing decisions which will have different effects on the investment adviser, the Service Provider and the Fund. The participation of the Executive Officers in such activities is inherent in the contractual relationship between the Fund and the investment adviser and the Service Provider and is consistent with the performance by the Executive Officers of their duties as officers of the Fund. Thus, if such participation is performed in confor mity with the provisions of the Investment Company Act and the Investment Advisers Act, it will be deemed to have been handled ethically. In addition, it is recognized by the Fund’s Board of Trustees/Directors (the “Board”) that the Executive Officers may also be officers or employees of one or more other investment companies covered by other Codes.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act. The following list provides examples of conflicts of interest under the Code, but the Registrant’s Executive Officers should keep in mind that these examples are not exhaustive. The overarching principle is that the personal interest of an Executive Officer should not be placed improperly before the interest of the Fund.

Each Covered Officer must:

►	not use his/her personal influence or personal relationships improperly to influence
	investment decisions or financial reporting by the Fund whereby the Executive Officer
	would benefit personally to the detriment of the Fund;
►	not cause the Fund to take action, or fail to take action, for the individual personal
	benefit of the Executive Officer rather than for the benefit of the Fund; and
►	not use material non-public knowledge of portfolio transactions made or contemplated
	for the Fund to trade personally or cause others to trade personally in contemplation of
	the market effect of such transactions.

Additionally, conflicts of interest may arise in other situations, the propriety of which may be discussed, if material, with the Fund’s Chief Compliance Officer (“CCO”). Examples of these include:

►	service as a director/trustee on the board of any public or private company;
►	the receipt of any non-nominal gifts;
►	the receipt of any entertainment from any company with which the Fund has current or
	prospective business dealings unless such entertainment is business-related, reasonable
	in cost, appropriate as to time and place, and not so frequent as to raise any question of
	impropriety (or other formulation as the Fund already uses in another code of conduct);
►	any ownership interest in, or any consulting or employment relationship with, any of
	the Fund’s service providers, other than its investment adviser, any sub-adviser,
	principal underwriter, administrator or any affiliated person thereof; and
►	a direct or indirect financial interest in commissions, transaction charges or spreads paid
	by the Fund for effecting portfolio transactions or for selling or redeeming shares other
	than an interest arising from the Executive Officer’s employment, such as compensation
	or equity ownership.

III. Disclosure & Compliance

►	Each Executive Officer should familiarize himself or herself with the disclosure
	requirements generally applicable to the Fund;
►	Each Executive Officer should not knowingly misrepresent, or cause others to
	misrepresent, facts about the Fund to others, whether within or outside the Fund,
	including to the Fund’s directors and auditors, and to governmental regulators and self-
	regulatory organizations;
►	Each Executive Officer should, to the extent appropriate within his/her area of
	responsibility, consult with other officers and employees of the Fund and the Fund’s
	adviser or any sub-adviser with the goal of promoting full, fair, accurate, timely and

3 of 6 

	understandable disclosure in the reports and documents the Fund files with, or submits
	to, the SEC and in other public communications made by the Fund; and
►	It is the responsibility of each Executive Officer to promote compliance with the
	standards and restrictions imposed by applicable laws, rules and regulations.

IV. Reporting & Accountability

Each Executive Officer must:

►	upon adoption of the Code (or thereafter as applicable, upon becoming an Executive
	Officer), affirm in writing to the Fund’s CCO that he/she has received, read, and
	understands the Code;
►	annually thereafter affirm to the Fund’s CCO that he/she has complied with the
	requirements of the Code;
►	not retaliate against any employee or Executive Officer or their affiliated persons for
	reports of potential violations that are made in good faith;
►	notify the Fund’s CCO promptly if he/she knows of any violation of this Code (Note:
	failure to do so is itself a violation of this Code); and
►	report at least annually any change in his/her affiliations from the prior year.

The Fund’s CCO is responsible for applying this Code to specific situations in which questions are presented under it and has the authority to interpret this Code in any particular situation. However, any approvals or waivers sought by the Principal Executive Officer will be considered by the Fund’s Board or the Compliance Committee thereof (the “Committee”).

The Fund will follow these procedures in investigating and enforcing this Code:

►	the Fund’s CCO will take all appropriate action to investigate any potential violations
	reported to him/her;
►	if, after such investigation, the CCO believes that no violation has occurred, the CCO is
	not required to take any further action;
►	any matter that the CCO believes is a violation will be reported to the Board or, if
	applicable, Compliance Committee;
►	if the Board or, if applicable, Compliance Committee concurs that a violation has
	occurred, the Board, either upon its determination of a violation or upon
	recommendation of the Compliance Committee, if applicable, will consider appropriate
	action, which may include review of, and appropriate modifications to, applicable
	policies and procedures; notification to appropriate personnel of the Service Provider or
	the investment adviser or its board; or a recommendation to dismiss the Registrant’s
	Executive Officer;

4 of 6 

►	the Board, or if applicable the Compliance Committee, will be responsible for granting
	waivers, as appropriate; and
►	any changes to or waivers of this Code will, to the extent required, be disclosed as
	provided by SEC rules.

V. Other Policies & Procedures

This Code shall be the sole code of ethics adopted by the Fund for purposes of Section 406 of the Sarbanes-Oxley Act of 2002 and the rules and forms applicable to registered investment companies thereunder. Insofar as other policies or procedures of the Fund, the Fund’s adviser, any sub-adviser, principal underwriter or other service providers govern or purport to govern the behavior or activities of the Registrant’s Executive Officers who are subject to this Code, they are superseded by this Code to the extent that they overlap or conflict with the provisions of this Code. The Fund’s and its investment adviser’s codes of ethics under Rule 204A-1 under the Investment Advisers Act and Rule 17j-1 under the Investment Company Act, respectively, are separate requirements applying to the Registrant’s Executive Officers and others, and are not part of this Code.

VI. Amendments

Any amendments to this Code, other than amendments to Exhibit A, must be approved or ratified by a majority vote of the Fund’s Board, including a majority of independent directors.

VII. Confidentiality

All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the Fund’s Board and its counsel, the investment adviser and the relevant Service Providers.

VIII. Internal Use

The Code is intended solely for the internal use by the Fund and does not constitute an admission, by or on behalf of the Fund, as to any fact, circumstance, or legal conclusion.

JOHN HANCOCK FUNDS

GOVERNANCE COMMITTEE CHARTER

A. Composition. The Governance Committee shall be composed entirely of Trustees who are "independent" as defined in the rules of the New York Stock Exchange ("NYSE") and the NASDAQ Stock Market, Inc. ("NASDAQ") or any other exchange, as applicable, and are not "interested persons" as defined in the Investment Company Act of 1940 of any of the funds, or of any fund's investment adviser or principal underwriter (the "Independent Trustees") who are designated for membership from time to time by the Board of Trustees. The Chairman of the Board shall be a member of the Governance Committee.

B. Overview. The overall charter of the Governance Committee is to make recommendations to the Board on issues related to corporate governance applicable to the Independent Trustees and to the composition and operation of the Board, and to assume duties, responsibilities and functions to recommend nominees to the Board, together with such additional duties, responsibilities and functions as are delegated to it from time to time.

C. Specific Responsibilities. The Governance Committee shall have the following duties and powers, to be exercised at such times and in such manner as the Committee shall deem necessary or appropriate:

1. Except where the funds are legally required to nominate individuals recommended by others, to recommend to the Board of Trustees individuals for nomination to serve as Trustees.

2. To consider, as it deems necessary or appropriate, the criteria for persons to fill existing or newly created Trustee vacancies. The Governance Committee shall use the criteria and principles set forth in Annex A to guide its Trustee selection process.

4. To consider and recommend the duties and compensation of the Chairman of the Board.

5. To consider and recommend changes to the Board regarding the size, structure, and composition of the Board.

6. To evaluate, from time to time, the retirement policies for the Independent Trustees.

To develop and recommend to the Board guidelines for corporate governance ("Corporate Governance Guidelines") for the funds that take into account the rules of the NYSE and any applicable law or regulation, and to periodically review and assess the Corporate Governance Guidelines and recommend any proposed changes to the Board for approval.

8. To monitor all expenditures of the Board or the Committees or the Independent Trustees not otherwise incurred and/or monitored by a particular Committee, including, but not limited to: legal, consulting, and D&O insurance costs; association dues, including Investment Company Institute membership dues; meeting expenditures and policies relating to

reimbursement of travel expenses and expenses associated with offsite meetings; expenses associated with Trustee attendance at educational or informational conferences; and publication expenses.

9. To consider, evaluate and make recommendations and necessary findings regarding independent legal counsel and any other advisers, experts or consultants, that may be engaged by the Board of Trustees, by the Trustees who are not "interested persons" as defined in the Investment Company Act of 1940 of any of the funds or any fund's investment adviser or principal underwriter, or by the Governance Committee, from time to time, other than as may be engaged directly by another Committee.

10. To periodically review the Board's committee structure and the charters of the Board's committees, and recommend to the Board of Trustees changes to the committee structure and charters as it deems appropriate.

11. To coordinate and administer an annual self-evaluation of the Board, which will include, at a minimum, a review of its effectiveness in overseeing the number of funds in the fund complex and the effectiveness of its committee structure.

12. To report its activities to Board of Trustees and to make such recommendations with respect to the matters described above and other matters as the Governance Committee may deem necessary or appropriate.

ANNEX A

General Criteria

1. Nominees should have a reputation for integrity, honesty and adherence to high ethical standards.

2. Nominees should have demonstrated business acumen, experience and ability to exercise sound judgments in matters that relate to the current and long-term objectives of the funds and should be willing and able to contribute positively to the decision-making process of the funds.

3. Nominees should have a commitment to understand the funds, and the responsibilities of a trustee/director of an investment company and to regularly attend and participate in meetings of the Board and its committees.

4. Nominees should have the ability to understand the sometimes conflicting interests of the various constituencies of the funds, including shareholders and the management company, and to act in the interests of all shareholders.

5. Nominees should not have, nor appear to have, a conflict of interest that would impair their ability to represent the interests of all the shareholders and to fulfill the responsibilities of a director/trustee.

Application of Criteria to Existing Trustees

The renomination of existing Trustees should not be viewed as automatic, but should be based on continuing qualification under the criteria set forth above. In addition, the Governance Committee shall consider the existing Trustee's performance on the Board and any committee.

Review of Shareholder Nominations

Any shareholder nomination must be submitted in compliance with all of the pertinent provisions of Rule 14a-8 under the Securities Exchange Act of 1934 in order to be considered by the Governance Committee. In evaluating a nominee recommended by a shareholder, the Governance Committee, in addition to the criteria discussed above, may consider the objectives of the shareholder in submitting that nomination and whether such objectives are consistent with the interests of all shareholders. If the Board determines to include a shareholder's candidate among the slate of its designated nominees, the candidate's name will be placed on the funds' proxy card. If the Board determines not to include such candidate among its designated nominees, and the shareholder has satisfied the requirements of Rule 14a-8, the shareholder's candidate will be treated as a nominee of the shareholder who originally nominated the candidate. In that case, the candidate will not be named on the proxy card distributed with the funds' proxy statement.

As long as an existing Independent Trustee continues, in the opinion of the Governance Committee, to satisfy the criteria listed above, the Committee generally would favor the re-nomination of an existing Trustee rather than a new candidate. Consequently, while the Governance Committee will consider nominees recommended by shareholders to serve as trustees, the Governance Committee may only act upon such recommendations if there is a vacancy on the Board, or the Governance Committee determines that the selection of a new or additional Trustee is in the best interests of the fund. In the event that a vacancy arises or a change in Board membership is determined to be advisable, the Governance Committee will, in addition to any shareholder recommendations, consider candidates identified by other means, including candidates proposed by members of the Governance Committee. The Governance Committee may retain a consultant to assist the Committee in a search for a qualified candidate.
