They are particularly useful guides to keep in mind today, at a time when markets around the globe are being buffeted by problems in the financial and real estate industries and by concerns about a slowing economy. After an extended period of steady economic growth with sustained low unemployment and low inflation, the U.S. economy ran into difficulty as 2007 drew to a close. Investors in subprime mortgages were forced to mark down the value of their assets, imperiling leveraged balance sheets. The ensuing credit crunch forced central banks in the United States and Europe to assume the role of "lender of last resort" to keep credit markets functioning. Conditions worsened in the first quarter of 2008, as falling prices, margin calls and deleveraging continued and while the auction-rate preferred market seized up. By then, recession talk was widespread as concern grew that falling home prices, rising unemployment, sharply rising food and energy prices, and disruptions in financial markets posed a significant threat to economic growth. In the next few months, though, there were no further banking crises, and recession fears began to fade in light of positive economic news. However a seemingly unstoppable rise in the price of oil became a new source of recession fears. Markets reacted poorly to the developments leading up to the near failure of Bear Stearns, with fixed-income credit spreads (the difference in rates between corporate and U.S. government bonds) widening dramatically and stock markets declining, wiping out the positive returns markets had delivered in the preceding calendar year. Treasury bond prices rose as the market underwent a classic "flight to quality." Those trends reversed in the months after the fall of Bear Stearns, as stock markets rallied, recouping much of their first-quarter losses, while Treasury bond prices declined. The stock market then reversed direction yet again, falling sharply to end June near earlier lows while Treasury bond prices ended June 2008 near end-of-year levels. In the 12 months ending June 30, 2008, the Dow Jones Industrial Average and Standard & Poor's 500 Index each declined 13%, the NASDAQ Composite Index fell 12%, and the MSCI EAFE Developed Market Index of international stock markets fell 10%. In each case, the majority of the decline was concentrated in the month of June. Very strong performance in the second half of 2 Pioneer Cullen Value Fund | Annual Report | 6/30/08 2007, combined with performance in line with other equity indices in the most recent six months helped the MSCI Emerging Markets Index to a gain of 5% over the 12-month period. The U.S. investment-grade bond market, as measured by the Lehman Brothers Aggregate Bond Index, rose 7% over the 12 months, but the U.S. high-yield bond market, as measured by the Merrill Lynch High Yield Bond Master II Index, fell 2% as its higher coupon yield could not offset the fall in bond prices triggered by widening credit spreads. Looking forward, the risk of a 2008 recession seems diminished, but higher commodity prices, lower real estate prices, and a weakened banking system still pose substantial risks to the real economy. On the other hand, a weak U.S. dollar and substantial fiscal and monetary stimulus are potent support for the economy. Markets remain volatile, and falling risk tolerances and deleveraging may depress asset prices in the short term, but equity and corporate bond valuations look attractive over a longer time horizon unless the U.S. economy falls into a severe and protracted recession. Sudden swings in the markets are always to be expected, but they are difficult to time. Maintaining a long-term time horizon, being diversified, and paying attention to asset allocation are important investment principles. As always, we encourage you to work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective and to adhere to a strategic plan rather than letting emotion drive investment decisions.

Pioneer Cullen Value Fund | Annual Report | 6/30/08 3 Portfolio Management Discussion | 6/30/08 Equity markets, despite some brief rallies, tumbled during the 12-months ended June 30, 2008, as weakness in the financials sector and housing market raised concerns about the strength of the domestic economy. In the following interview, James P. Cullen discusses the factors that influenced the performance of Pioneer Cullen Value Fund during the 12 months. Mr. Cullen, President of Schafer Cullen Capital Management, oversees the team responsible for the daily management of the Fund. Q How did the Fund perform during the 12 months ended June 30, 2008? A Pioneer Cullen Value Fund Class A shares produced a total return of -9.22% for the fiscal year ended June 30, 2008, while the Standard & Poor's 500 Index (the S&P 500) returned -13.11% and the Russell 1000 Value Index (the Russell Index) returned -18.78% over the same 12-month period. In addition, the average return of the 551 funds in the Lipper Large-Cap Value category was -17.04% over the 12-month period ended June 30, 2008. Q What was your principal strategy during the 12 months ended June 30, and how did it affect performance? A Most equity prices showed sharp declines for the period in a slump that began in the financials sector over concerns about problems in housing and subprime-mortgage debt. We believe the economy has been able to stay out of recession (which is defined as two consecutive quarters of negative growth in gross domestic product) primarily because of the good results from corporations heavily involved in international commerce. In the last quarter, for example, almost 25% of the total profits of S&P 500 companies came from international business operations. We maintained a relatively conservative portfolio for the Fund throughout the 12 months, and this positioning helped in a very volatile market. For example, we went heavy on consumer staples stocks, where stock selection helped support the Fund's results, despite some profit taking by investors in the final six months of the annual reporting period. In general, we maintained our longer-term investment discipline, keeping the portfolio well diversified by industry and focusing on stocks with relatively low price-to-earnings ratios and excellent long-term earnings prospects. We take a five-year outlook when we invest the Fund in a company, and we expect to hold the position for an extended period of time, barring any unforeseen deterioration in company fundamentals. 4 Pioneer Cullen Value Fund | Annual Report | 6/30/08 We established two major new positions for the Fund during the period, both in the health care sector: Johnson & Johnson and Eli Lilly. Pharmaceuticals stocks have been out of favor recently, both because of worries about pending expirations of profitable patents and because of concerns about pressure on Congress to limit Medicare reimbursements. Although the industry has underperformed, we believe the two corporations have the potential to do well, especially in a down market, because their earnings are driven by demand for medical necessities rather than for discretionary items. Johnson & Johnson, a more diversified health care products company that is less dependent on results from its pharmaceuticals operation, benefits from a well known brand name in markets throughout the world, giving it a distinctive advantage as global demand for health care products continues to grow. Eli Lilly has a new chief executive, who we believe has a realistic view of the political pressures calling for containment of health care costs. Moreover, the company has a distinctive advantage because of its relatively full pipeline of potential new drug products in development. We also were attracted by Eli Lilly's generous dividend yield and the fact that the company is small enough to make it an attractive acquisition target by other, larger companies. We went light on financials holdings in the Fund, but maintained a solid position in JPMorgan Chase, which we believe to be the best-managed and financially strongest of the major financial institutions. We also have maintained somewhat smaller positions for the Fund in Merrill Lynch and Morgan Stanley because of their international exposure, and because each company appears small enough to be a potential takeover target. In general, though, we believed it was difficult to evaluate the underlying value in many financials companies, and so we de-emphasized the group during the 12-month period, having sold the Fund's earlier positions in regional banks such as Wachovia, Wells Fargo and Regions Financial. The Fund took advantage of a pretty strong climate for the energy sector during the 12-month period, and benefited from good performance produced by several energy-related holdings, including the Brazilian oil company Petrobras, a relatively new position. Q What is your investment outlook? A While the deceleration in U.S. economic growth is unmistakable, we think most U.S. corporations have stronger financial balance sheets than seen in earlier slumps, with many companies able to withstand weakness in the domestic economy because of their international businesses. American corporations have become very good at competing in world markets, which gives them new sources of profits and greater resilience in the face of problems in the United States. Pioneer Cullen Value Fund | Annual Report | 6/30/08 5 We believe it is important to keep a longer-term horizon and not make the mistake of reacting to the daily headlines. We have examined historical trends over the past 40 years -- during which there were six recessions -- to see what happened after significant slumps in the equity market. We have found that investors who purchased at the worst possible times (shortly before the start of the slumps) typically have captured double-digit returns over the subsequent five years, if they remained disciplined and were careful about the prices they paid for stocks. We intend to remain disciplined, and we continue to believe that keeping a five-year horizon and investing in fundamentally solid companies whose stock valuations are cheap will enable the Fund to do well over the longer term, despite any short-term market problems.

Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Performance for periods prior to the inception of Y shares reflects the NAV performance of the Fund's A shares. The performance does not reflect differences in expenses, including the Rule 12b-1 fees applicable to A shares. Since fees for A shares are generally higher than those of Y shares, the performance shown for Y shares prior to their inception would have been higher. Class Y shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors. All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ. Performance results reflect any applicable expense waivers in effect during the periods shown. Without such waivers Fund performance would be lower. Waivers may not be in effect for all funds. Certain fee waivers are contractual through a specified period. Otherwise, fee waivers can be rescinded at any time. See the prospectus and financial statements for more information. The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares. Pioneer Cullen Value Fund was created through the reorganization of the predecessor Cullen Value Fund on 2/28/05. The performance of Class Y shares of the Fund from July 1, 2000 to February 25, 2005 is the performance of Cullen Value Fund's single class, which has not been restated to reflect any differences in expenses. Cullen Value Fund had higher expenses than those of the Fund's Class Y shares. Pioneer Cullen Value Fund | Annual Report | 6/30/08 13 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables - -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value [divided by] $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Cullen Value Fund Based on actual returns from January 1, 2008 through June 30, 2008. Share Class A B C R Y Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 $ 1,000.00 $ 1,000.00 Value On 1/1/08 - ------------------------------------------------------------------------------------------ Ending Account Value $ 849.84 $ 849.63 $ 849.49 $ 850.33 $ 849.51 (after expenses) On 6/30/08 - ------------------------------------------------------------------------------------------ Expenses Paid $ 5.01 $ 8.83 $ 8.46 $ 3.45 $ 6.44 During Period* - ------------------------------------------------------------------------------------------ * Expenses are equal to the Fund's annualized expense ratio of 1.09%, 1.92%, 1.84%, 1.40% and 0.75% for Class A, Class B, Class C, Class R and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 182/366 (to reflect the one-half year period). 14 Pioneer Cullen Value Fund | Annual Report | 6/30/08 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio 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 with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Organization and Significant Accounting Policies Pioneer Cullen Value Fund (the Fund) is a diversified series of Pioneer Series Trust III, a Delaware statutory trust registered under the Investment Company Act of 1940 as an open-end management investment company. The investment objective of the Fund is to seek capital appreciation. Current income is a secondary objective. The Fund offers five classes of shares -- Class A, Class B, Class C, Class R, and Class Y shares. Class R shares were first publicly offered on November 1, 2006. Each class of shares represents an interest in the same portfolio of investments of the Fund and has equal rights to voting, redemptions, dividends and liquidation, except that the level of transfer agent and distribution fees may differ among classes. Class A, Class B, Class C, and Class R shareowners have exclusive voting rights with respect to the distribution plan for each class. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting year. Actual results could differ from those estimates. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Fund's prospectuses contain information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's risks. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the Pioneer Cullen Value Fund | Annual Report | 6/30/08 31 date of valuation, or securities for which sale prices are not generally reported, are valued at the mean between the last bid and asked prices. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund may also use the fair value of a security, including a non-U.S. security, when the closing market price on the principal exchange where the security is traded no longer reflects the value of the security. At June 30, 2008 there were no securities fair valued. Temporary cash investments are valued at cost which approximates market value. Dividend income is recorded on the ex-dividend date except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Dividend and interest income is recorded on the accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. Tax years prior to 2004 are closed (not subject to examination by tax authorities) due to the expiration of statute of limitations; all other tax years are open. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. At June 30, 2008, The fund had a net capital loss carryforward of $11,033,627 which will expire in 2016 if not utilized. The Fund has elected to defer $89,056,914 of capital losses recognized between November 1, 2007 and November 30, 2007 to its fiscal year ending June 30, 2009. 32 Pioneer Cullen Value Fund | Annual Report | 6/30/08 At June 30, 2008, the Fund has reclassified $858 to decrease undistributed net investment income and $858 to increase accumulated net realized gain on investments, to reflect permanent book/tax differences. The reclassification has no impact on the net assets of the Fund and presents the Fund's capital accounts on a tax basis. The tax character of distributions paid during the years ended June 30, 2008 and June 30, 2007 was as follows: 2008 2007 Distributions paid from: Ordinary income $40,293,220 $19,583,573 Long-term capital gain 7,607,797 1,043,128 --------------------------------------------------------------------------- Total $47,901,017 $20,626,701 =========================================================================== The following shows the components of distributable earnings on a federal income tax basis at June 30, 2008: 2008 Distributable earnings: Undistributed ordinary income $ 23,820,845 Capital loss carryforward (11,033,627) Current year Post-October loss deferred (89,056,914) Unrealized appreciation 47,813,628 --------------------------------------------------------------------------- Total $ (28,456,068) =========================================================================== The difference between book-basis and tax-basis unrealized appreciation is attributable to the tax deferral of losses on wash sales. C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned approximately $38,554 in underwriting commissions on the sale of Class A shares during the year ended June 30, 2008. D. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on their respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class B, Class C, and Class R shares of the Fund, respectively. Class Y shares are not subject to a distribution plan (see Note 4). Shareowners of each class participate in all expenses and fees paid to the Pioneer Cullen Value Fund | Annual Report | 6/30/08 33 transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner, at the same time, on the same day, and in the same amount, except that Class A, Class B, Class C, Class R, and Class Y shares can bear different transfer agent and distribution expense rates. E. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest received from counterparties, is required to be at least equal to or in excess of the value of the repurchase agreement at the time of purchase. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian, or subcustodians. The Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for determining that the value of the collateral remains at least equal to the repurchase price. F. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a loan, the Fund receives collateral and earns income in the form of negotiated lenders' fees. The Fund also continues to receive interest or payments in lieu of dividends on the securities loaned. Gain or loss on the fair value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The loans are secured by collateral which is required to be at least 102%, at all times, of the fair value of the securities loaned. The amount of collateral is required to be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right under the lending agreement to recover the securities from the borrower on demand. The Fund invests cash collateral in cash equivalent investments. Securities lending collateral is managed by Credit Suisse. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. PIM receives a basic fee that is calculated at the annual rate of 0.70% of the Fund's average daily net assets up to $1 billion, 0.65% of the next $1 billion, 0.60% of the next $1 billion, and 0.55% of assets over $3 billion. For the year ended June 30, 2008, the effective management fee (net of waivers and/or assumption of expenses) was equivalent to 0.64% of the Fund's average daily net assets. 34 Pioneer Cullen Value Fund | Annual Report | 6/30/08 PIM, and not the Fund, pays a portion of the fee it receives from the Fund to Cullen LLC as compensation for Cullen's subadvisory services to the Fund. Through November 1, 2009 PIM has agreed not to impose all or a portion of its management fee and to assume other operating expenses of the Fund to the extent necessary to limit Class A expenses to 1.25% of the average daily net assets attributable to Class A shares.

Distribution and Service Plans The Fund adopted a Plan of Distribution with respect to Class A, Class B, Class C, and Class R shares in accordance with Rule 12b-1 of the Investment Company Act of 1940. Effective February 1, 2008, under the Class A Plan, the Fund pays PFD a service fee equal to 0.25% of the average daily net assets attributable to Class A shares to finance activities primarily intended to result in the sale of Class A shares.

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. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of June 30, 2008 by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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 Pioneer Cullen Value Fund as of June, 30, 2008, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/Ernst + Young LLP Boston, Massachusetts August 18, 2008 Pioneer Cullen Value Fund | Annual Report | 6/30/08 39 Approval of Investment Advisory Agreement Pioneer Investment Management, Inc. (PIM) serves as the Fund's investment adviser pursuant to an investment advisory agreement between PIM and the Fund. The Trustees of the Fund, as required by law, determine annually whether to continue the investment advisory agreement for the Fund. In connection with their most recent consideration of the investment advisory agreement for the Fund, the Trustees received and reviewed a substantial amount of information provided by PIM in response to requests of the independent Trustees and their independent legal counsel. The independent Trustees met on a number of occasions with PIM and also separately with their independent legal counsel to evaluate and discuss the information provided to them by PIM. At a meeting held on November 13, 2007, based on their evaluation of the information provided by PIM, the Trustees, including the independent Trustees voting separately, unanimously approved the continuation of the investment advisory agreement for another year. At a meeting held on January 8, 2008, the Trustees considered whether an amended and restated investment advisory agreement for the Fund should be approved for an initial period ending December 31, 2009. The management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement is the same as the management fee provided in the previously approved investment advisory agreement. Based on their evaluation of the information provided by PIM, including the information provided by PIM in connection with the Trustees' most recent approval of the continuation of the previous investment advisory agreement, the Trustees, including the independent Trustees voting separately, unanimously approved the amended and restated investment advisory agreement. Shareholders of the Fund approved the amended and restated investment advisory agreement at a meeting held on May 13, 2008. In considering the amended and restated investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the amended and restated investment advisory agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that were provided by PIM to the Fund under the previous investment advisory agreement, and that would continue to be provided by PIM to the Fund under the amended and restated investment advisory agreement, taking into account the investment objective and strategy of the Fund and the information related to 40 Pioneer Cullen Value Fund | Annual Report | 6/30/08 the Fund provided to the Trustees at each quarterly meeting. The Trustees reviewed the terms of the amended and restated investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also considered PIM's compliance and legal resources and personnel. In addition, the Trustees considered the other services that PIM provided under the previous investment advisory agreement and that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement and that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. It was noted that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including officers) as are necessary for the Fund's operations. The Trustees considered the fees paid to PIM for the provision of such services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement, were satisfactory and consistent with the terms of the amended and restated investment advisory agreement. Performance of the Fund The Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the average performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees noted that the Fund commenced operations on March 1, 2005. They considered that the Fund's annualized total return was in the fifth quintile of its Morningstar category for the one year period ended June 30, 2007 and in the first quintile of its Morningstar category for the three and five year periods ended June 30, 2007. (In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile.) After discussing the reasons for the Fund's short-term underperformance with PIM, the Trustees concluded that the investment performance of the Fund was satisfactory. Management Fee and Expenses The Trustees considered that the management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement would be the same as the management fee to be paid by the Fund under the previously approved investment advisory agreement. The Trustees considered information on the fees and expenses of the Fund in comparison to the management Pioneer Cullen Value Fund | Annual Report | 6/30/08 41 fees of its peer group of funds as classified by Morningstar and the expense ratios of a peer group of funds selected on the basis of criteria determined by the independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2007 was in the second quintile relative to the management fees paid by other funds in its peer group Morningstar category for the comparable period. The Trustees also considered that the Fund's expense ratio for the twelve months ended June 30, 2007 was in the third quintile relative to its Strategic Insight peer group. It was noted that PIM did not currently manage any accounts with an investment objective and strategies that were similar to the Fund. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of services provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies. The Trustees also concluded that the Fund's expense ratio was reasonable, taking into account the size of the Fund, the quality of services provided by PIM, the investment performance of the Fund and the contractual expense limitation agreed to by PIM with respect to the Fund. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees recognized that PIM should be entitled to earn a reasonable level of profit for the services provided to the Fund. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered the economies of scale with respect to the management of the Fund, whether the Fund had appropriately benefited from any economies of scale, and whether there was potential for realization of any further economies of scale. 42 Pioneer Cullen Value Fund | Annual Report | 6/30/08 The Trustees concluded that, because of the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels, any perceived or potential economies of scale would be shared between PIM and the Fund. Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered that affiliates of PIM serve as the Fund's transfer agent and distributor. The Trustees considered the receipt by PIM and its affiliates of sales loads and payments under Rule 12b-1 plans in respect of the Fund and the other Pioneer funds and the benefits to PIM and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services. The Trustees further considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the independent Trustees, concluded that the terms of the amended and restated investment advisory agreement between PIM and the Fund, including the fees payable thereunder, were fair and reasonable and voted to approve the amended and restated investment advisory agreement for the Fund.

PIONEER FUNDS APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES PROVIDED BY THE INDEPENDENT AUDITOR SECTION I - POLICY PURPOSE AND APPLICABILITY The Pioneer Funds recognize the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Pioneer Investment Management, Inc ("PIM"), the audit committee and the independent auditors. The Funds recognize that a Fund's independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund's independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence. Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approval is required pursuant to Rule 210.2-01(c)(7)(ii). In addition to the procedures set forth in this policy, any non-audit services that may be provided consistently with Rule 210.2-01 may be approved by the Audit Committee itself and any pre-approval that may be waived in accordance with Rule 210.2-01(c)(7)(i)(C) is hereby waived. Selection of a Fund's independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.
