LETTER TO SHAREOWNERS 4/30/05
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------

U.S. stocks moved higher early in 2005, with the Standard & Poor's 500 Stock
Index and the Dow Jones Industrial Average advancing to three-year highs in
early March. But from then on, soaring prices for heating oil and gasoline,
plus the steady ratcheting up of interest rates by the Federal Reserve Board
overwhelmed sentiment and caused stocks to retrace their gains. By the end of
April, the Dow Industrials, the S&P 500 and the tech-heavy NASDAQ composite
were in negative territory for the year.

With investors less welcoming of risk and the economy giving mixed signals,
value stocks were more resilient than growth stocks. In addition,
large-capitalization stocks held up better than small- and mid-sized issues
that might be more vulnerable in an economic "soft patch," in the phrase of
Federal Reserve Board Chairman Alan Greenspan.

Determined to prevent damaging inflation, the Fed has repeatedly raised
short-term interest rates. As a result, bond returns were modestly negative in
most sectors. Fixed-income investors also became more risk-averse; high-yield
and other corporate sectors retrenched after a run of stellar performance while
Treasuries and mortgage-backed securities showed small declines, with long-term
issues showing positive. Municipal revenue bonds trended higher even against a
backdrop of heavy new issuance by states and localities.

Higher U.S. interest rates enhanced the dollar's appeal and brought at least a
pause in its long, sharp drop. But the stronger dollar muted returns for U.S.
investors in overseas markets. Globally, economies rich in metals and other
industrial commodities continued to thrive on heavy demand from China and
elsewhere. Meanwhile, growth in Japan may have stalled, and Europe's expansion
moved ahead slowly.

We believe that the U.S. economy and corporate earnings will continue to grow
at a moderate pace. Oil prices have receded from their record highs, but high
energy costs and rising interest rates may be in the headlines for a while.
Looking beyond present concerns, Pioneer's global investment experts continue
to find stocks and bonds with attractive long-term potential for our domestic
and international funds.

Expanding your opportunities

This period was like all others; different classes of investments delivered
different returns. That's why allocating your portfolio across several
investment categories is one way to seek wider opportunities. Pioneer's
disciplined approach and growing range of products are designed to help you
achieve this important objective. For thoughtful guidance on how to align your
portfolio with your goals, contact your financial professional.

Please consider a fund's investment objective, risks, charges and expenses
carefully before investing. The prospectus contains this and other information
about each fund and should be read carefully before you invest or send money.
To obtain a prospectus and for other information on any Pioneer fund, contact
your financial advisor, call 1-800-225-6292 or visit our web site at

Call 1-800-225-6292 or visit www.pioneerfunds.com for the most recent month-end
performance results. 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.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. 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.

The Russell 1000 Value Index measures the performance of large-cap U.S. value
stocks. Index returns assume reinvestment of dividends and, unlike Fund returns,
do not reflect any fees, expenses or sales charges. You cannot invest directly

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 - $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.

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.

PORTFOLIO MANAGEMENT DISCUSSION 4/30/05
- --------------------------------------------------------------------------------

In the following discussion, John Carey, portfolio manager of Pioneer Equity
Income Fund reviews the overall market and the performance of Pioneer Equity
Income Fund over the six months ended April 30, 2005.

Q:  How did the Fund perform during the period in relation to the overall stock
    market and its peer group?

A:  Pioneer Equity Income Fund showed positive performance in the six months
    ended April 30, 2005. The total return on Class A shares was 6.82% at net
    asset value. By comparison, the Russell 1000 Value Index and the Standard &
    Poor's 500, both of them unmanaged indexes of the general stock market,
    rose, respectively, 6.72% and 3.28%. The average fund in the Lipper
    Analytical Services equity-income category rose 5.35%. The rates of
    appreciation for both the Fund and the market slowed from the pace of the
    previous six months, but investors were still rewarded for their efforts.
    Concerns about rising short-term interest rates, high oil prices, the weak
    dollar, and trade deficits notwithstanding, investors appeared to take heart
    from the growing economy and improving corporate earnings.

    Call 1-800-225-6292 or visit www.pioneerfunds.com for the most recent
    month-end performance results. 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.

    Throughout the period, your Fund stayed fully invested in dividend-paying,
    United States-headquartered companies, researched and monitored by our
    independent staff of securities analysts. We have always believed that the
    foundation of a sound mutual-fund management strategy is research. At
    Pioneer in Boston we have approximately twenty full-time analysts whose
    responsibility it is to keep track of their assigned industries and
    sectors and make investment recommendations. We are proud of the record of
    Pioneer Equity Income Fund using that careful, methodical, patient
    approach. In July the Fund will mark its 15th anniversary. Over the next
    fifteen years there will be both challenges and opportunities. We believe
    that our "all-weather" strategy is well suited to the normal stresses of
    economic and market cycles, and it is our intention to continue along the
    same path.

                                                                              11

- --------------------------------------------------------------------------------

Q:  What contributed to the above-average performance of the Fund in the
    six-month period?

A:  In general, more "value"-oriented strategies like ours did better than more
    "growth"-oriented approaches. We think, without being able to confirm it,
    that the new, favorable Federal tax treatment of qualified dividends
    provided ongoing support to income-producing stocks. We were struck by the
    superior returns on stocks in so-called "old economy" sectors, including
    energy, consumer staples, and utilities, and the persistently poor returns
    on information-technology stocks. Our sector positioning, which customarily
    emphasizes mature, financially strong, dividend-paying stocks, was the major
    reason for our outperformance. We note that the Fund also had an
    above-average weighting relative to the Russell 1000 Value Index in the
    well-performing health-care sector, and that, too, helped our relative
    returns.

    Among positive contributors to results were our shares of utilities
    Constellation Energy and Questar, oil producer ConocoPhillips, steel mill
    Roanoke Electric Steel, and pharmaceutical companies Merck and Abbott
    Laboratories. The Fund also saw a large gain on its holdings of May
    Department Stores, which received a premium take-over offer from Federated
    Department Stores. Our investment posture in financial services likewise
    contributed positively, though mainly through our successful avoidance of
    poor-performing JPMorgan Chase and American International Group.

    Negative impact was felt from our holdings of struggling auto manufacturer
    Ford Motor. Two other transportation-equipment-related stocks, PACCAR and
    Johnson Controls, also hurt somewhat. Finally, due to our longstanding
    policy against owning tobacco, liquor, and gambling stocks, we did not
    have shares of Altria, formerly Philip Morris, a relatively strong
    performer in the period.

Q:  Did you make any changes to the portfolio?

A:  Shareholders will note nine new entries to the portfolio and ten
    liquidations. Some of the purchases were securities we had owned previously
    and sold, but that we decided were worth revisiting. In that category were:
    Bristol-Myers Squibb, the pharmaceutical maker; Coca-Cola, the well-known
    beverages company; and Bank of America and Citigroup, the large banking and
    financial-services enterprises. In each case, the concerns that had prompted
    us earlier to sell the shares seemed diminished due to constructive actions
    on the part of the corporate management.

    Also new were: Compass Minerals, supplier of highway deicing salts;
    Citizens Communications, a Stamford, Connecticut-based
    telecommunications-services provider; Genuine Parts, a leading distributor
    of auto parts nationwide; and Atmos Energy, a Dallas, Texas-based
    distributor of natural gas. We also acquired shares of Wachovia in
    exchange for our shares of SouthTrust when Wachovia, a large regional
    bank, acquired our former holding.

    In addition to the sale of SouthTrust in the merger, we took gains on the
    sale of some of our cyclical stocks that we thought had reached ample
    values, including Phelps Dodge, Occidental Petroleum, Boeing, and General
    Dynamics. We also realized a profit on our sale of Simon Properties,
    likewise, in our minds, fully valued. General Motors was a less happy
    situation, but after pondering the serious financial questions surrounding
    the company, we decided that the stock was better to watch from a
    distance. Pfizer and International Business Machines also seemed less
    attractive to us than they had when we purchased them. Finally, we sold at
    a profit a small position in the Gap 5 3/4% convertible debenture.

Q:  What is your outlook, especially in view of rising interest rates?

A:  The striking thing about the bond market over the past year or so, since the
    Federal Reserve began raising short-term interest rates, has been the
    moderation in medium- and long-term rates. Evidently bond investors are not
    particularly fearful of inflation in coming years, and they are not
    demanding higher interest rates from borrowers over the more distant time
    periods. So one must be careful in speaking of "rising interest rates." The
    only rates that have risen are the very short-term rates. Nevertheless,
    there will be some pressures on earnings with the consequent flattening of
    the yield curve, particularly in the financial sector. Banks, for instance,
    will see their profit-margin "spreads" narrow as they find they have to pay
    higher interest rates to attract short-term deposits, but also find that
    they are loaning longer-term money at the same or even slightly lower rates
    than in the past. We shall be watching earnings closely over the next couple
    of quarters to see how companies are affected.

    High oil prices have also been a focus of investors, particularly as they
    reduce the amount of money consumers have to spend on other things and as
    they mean higher costs for businesses. Your Fund has participated in the
    profitability of the energy sector by owning shares of a number of the
    leading companies. We cannot predict where oil prices will go from here,
    though they have been

                                                                              13

    declining as we write this letter. We tend to agree with the forecasts for
    expanding demand for energy from the rapidly growing countries in Asia,
    including China and India, and we also remain unconvinced that there will
    always be plentiful supplies of oil at low production cost. Always,
    though, becoming nervous when there is too much of a consensus in one
    direction, we have lightened our weighting in energy from 10.4% of
    portfolio net assets at October 31, 2004, to 9.0% at April 30, 2005, even
    while the percentage weighting in our benchmark index, the Russell 1000
    Value, has grown, through appreciation, from 12.1% to 13.5%. We think that
    the current prices of many energy shares already reflect the good
    prospects.

    Otherwise, we think that the economy is still in reasonably good shape and
    observe that corporate earnings are still on an upswing. While
    acknowledging that market action is often less driven by current
    fundamentals and more influenced by expectations for the future, we remain
    fairly optimistic about the market and the chances of making money in it.
    Thank you for your support.

NOTES TO FINANCIAL STATEMENTS 4/30/05 (unaudited)

1.  Organization and Significant Accounting Policies

Pioneer Equity Income Fund (the Fund) is a Delaware statutory trust registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. The investment objectives of the Fund are current income
and long-term growth of capital from a portfolio consisting primarily of income
producing equity securities of U.S. corporations.

The Fund offers five classes of shares - Class A, Class B, Class C, Class R and
Class Y shares. Each class of shares represents an interest in the same
portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidation, except that each class of shares can
bear different transfer agent and distribution fees and have exclusive voting
rights with respect to the distribution plans that have been adopted by Class
A, Class B, Class C, and Class R shareowners, respectively. There is no
distribution plan for Class Y shareowners.

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 during the reporting period.
Actual results could differ from those estimates. 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 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 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

                                                                              31

    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 also
    may 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 April 30, 2005,
    there were no securities fair valued. Temporary cash investments are
    valued at amortized cost.

    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.

    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 either from or in
    excess of net investment income or net realized gain on investment
    transactions, or from paid-in capital, depending on the type of book/tax
    differences that may exist.

    At October 31, 2004, the Fund had a net capital loss carryforward of
    $3,442,687, which will expire in 2010 if not utilized.

                                                                  ------------
- --------------------------------------------------------------------------------


    The difference between book basis and tax-basis unrealized appreciation is
    attributable to the tax adjustments on partnerships, preferred stocks and
    REIT holdings.

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 UniCredito Italiano S.p.A.
    (UniCredito Italiano) earned approximately $74,591 in underwriting
    commissions on the sale of Class A shares during the six months ended,
    April 30, 2005.

D.  Class Allocations

    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 share all expenses and fees paid
    to the transfer agent, Pioneer Investment Management Shareholder Services,
    Inc. (PIMSS), for its ser-

                                                                              33

    vices, 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).
    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 the respective percentage of adjusted net assets at the beginning
    of the day.

    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, 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 fees.

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, with the Fund's custodian acting as the
    lending agent. When entering into a loan, the Fund receives collateral,
    which is maintained by the custodian 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 of at least 102%, at all times, of the fair value of the
    securities loaned. The amount of the collateral will be adjusted daily to
    reflect any price fluctuation in the value of the loaned securities. The
    Fund has the right under the lending agreements to recover the securities
    from the borrower on demand. The Fund invests cash collateral in the
    Securities Lending

    Fund's custodian.

2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredito Italiano, manages the
Fund's portfolio. PIM receives a basic fee that is calculated at the annual
rate of 0.60% of the Fund's average daily net assets up to $10 billion and
0.575% of the excess over $10 billion.

In addition, under the management and administrative agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. At April 30, 2005, $501,848 was payable to PIM
related to management fees, administrative costs and certain other services and
is included in due to affiliates.

3. Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides
substantially all transfer agent and shareowner services to the Fund at
negotiated rates. Included in due to affiliates is $257,985 in transfer agent
fees payable to PIMSS at April 30, 2005.

4. Distribution and Service Plans

The Fund adopted a Plan of Distribution for each class of shares, except Class
Y shares (Class A Plan, Class B Plan, Class C Plan, Class R Plan) in accordance
with Rule 12b-1 of the Investment Company Act of 1940. Pursuant to the Class A
Plan, the Fund pays PFD a service fee of up to 0.25% of the Fund's average
daily net assets attributable to Class A shares in reimbursement of its actual
expenditures to finance activities primarily intended to result in the sale of
Class A shares. Pursuant to the Class B Plan and the Class C Plan, the Fund
pays PFD 1.00% of the average daily net assets attributable to each class of
shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee
paid as compensation for personal services and/or account maintenance services
or distribution services with regard to Class B and Class C shares. Pursuant to
the Class R Plan, the Fund pays PFD 0.50% of the average daily net assets
attributable to Class R shares for distribution services. Included in due to
affiliates is $388,030 in distribution fees payable to PFD at April 30, 2005.
The Fund also has adopted a separate service plan for Class R shares (Service
Plan). The Service Plan authorizes the Fund to pay

                                                                              35

securities dealers, plan administrators or other service organizations that
agree to provide certain services to retirement plans or plan participants
holding shares of the Fund a service fee of up to 0.25% of the Fund's average
daily net assets attributable to Class R shares held by such plans.

In addition, redemptions of each class of shares (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). Effective February 1,
2004, a CDSC of 1.00% may be imposed on redemptions of certain net asset value
purchases of Class A shares within 18 months of purchase (12 months for shares
purchased prior to February 1, 2004). Class B shares subscribed on or after
December 1, 2004 that are redeemed within five years of purchase are subject to
a CDSC at declining rates beginning at 4.00%, based on the lower of cost or
market value of shares being redeemed. Shares purchased prior to December 1,
2004, remain subject to the CDSC in effect at the time those shares were
purchased. Redemptions of Class C shares within one year of purchase are
subject to a CDSC of 1.00%. Redemptions of Class R shares within 18 months of
purchase were subject to a CDSC of 1.00%. Effective July 1, 2004, the CDSC on
Class R shares was eliminated. Proceeds from the CDSCs are paid to PFD. For the
six months ended April 30, 2005, CDSCs in the amount of $126,068 were paid to
PFD.

5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS
resulting in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the six months ended April 30, 2005, the Fund's
expenses were reduced by $11,202 under such arrangements.

6. Line Of Credit Facility

The Fund, along with certain others in the Pioneer Family of Funds (the Funds),
collectively participate in a $50 million committed, unsecured revolving line
of credit facility. Borrowings are used solely for temporary or emergency
purposes. The Fund may borrow up to the lesser of $50 million or the limits set
by its prospectus for borrowings. Interest on collective borrowings is payable
at the Federal Funds Rate plus 1/2% on an annualized basis. The Funds pay an
annual commitment fee for this facility. The commitment fee is allocated among
such Funds based on their respective borrowing limits. For the

six months ended April 30, 2005, the Fund had no borrowings under this
agreement.

7. Affiliated Companies

The Fund's investments in certain companies exceed 5% of the outstanding voting
stock. Such companies are deemed affiliates of the Fund for financial reporting
purposes. The following summarizes transactions with affiliates of the Fund for
the six months ended, April 30, 2005:

FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN
APPROVING THE MANAGEMENT CONTRACT
- --------------------------------------------------------------------------------

The Investment Company Act of 1940 requires that both the Board of Trustees and
a majority of the Independent Trustees (collectively "the Trustees") vote
separately annually to approve the Fund's management contract (the "Management
Contract"). The Trustees have determined that the terms of the Management
Contract are fair and reasonable and that renewal of the contract will enable
the Fund to receive quality investment advisory services at a cost deemed
reasonable and in the best interests of the Fund and its shareholders. In
making such determinations, the Independent Trustees relied upon the assistance
of counsel to the Independent Trustees and counsel to the Fund.

Throughout the year, the Independent Trustees regularly met in executive
session separately from the Interested Trustees of the Fund and any officer of
Pioneer Investment Management, Inc., the Fund's adviser (the "Investment
Adviser"), or its affiliates. While the Trustees, including the Independent
Trustees, act on all major matters relating to the Fund, a significant portion
of the activities of the Board of Trustees (including certain of those
described herein) is conducted through committees, the members of which are
comprised exclusively of Independent Trustees. Such committee meetings are
attended by officers of the Fund or the Investment Adviser to the extent
requested by the members of the committee.

In evaluating the Management Contract, the Trustees conducted a review that was
specifically focused upon the renewal of the Management Contract, and relied
upon their knowledge, resulting from their meetings throughout the year, of the
Investment Adviser, its services and the Fund. Both in meetings specifically
dedicated to renewal of the Management Contract and at other meetings during
the course of the year, the Trustees, including the Independent Trustees,
received materials relating to the Investment Adviser's investment and
management services under the Management Contract. These materials included (i)
information on the investment performance of the Fund, a peer group of funds
and two indices, in each case selected by the Independent Trustees for this
purpose, (ii) sales and redemption data in respect to the Fund, (iii) the
general investment outlook in the markets in which the Fund invests, (iv)
arrangements in respect of the distribution of the Fund's shares, (v) the
procedures employed to determine the value of each of the Fund's assets, (vi)
the Investment Adviser's management of the relationships with the Fund's
unaffiliated service providers, (vii) the record of compliance with the Fund's
investment policies and restrictions and with the Fund's Code

38

- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

of Ethics and the structure and responsibilities of the Investment Adviser's
compliance department, (viii) the nature, cost and character of non-investment
management services provided by the Investment Adviser and its affiliates and
(ix) the disclosures included in the Fund's prospectuses and reports to
shareholders.

Specifically in connection with the Independent Trustees' review of the
Management Contract, the Independent Trustees requested and the Investment
Adviser provided additional information in order to evaluate the quality of the
Investment Adviser's services and the reasonableness of the fee under the
Management Contract. Among other items, this information included data or
analyses of (1) investment performance for one and three years and life of the
Fund periods for the Fund and a peer group selected by the Independent Trustees
for this purpose, (2) management fees incurred by a peer group of funds
selected by the Independent Trustees for this purpose, (3) the advisory fees of
comparable portfolios of other clients of the Investment Adviser, (4) expense
ratios for the Fund and a peer group of funds selected by the Independent
Trustees for this purpose, (5) the overall organization of the Investment
Adviser, (6) the Investment Adviser's financial results and condition,
including its and certain of its affiliates profitability from services
performed for the Fund, (7) transfer agency fees and administrative
reimbursements paid to the Investment Adviser or affiliates, (8) investment
management staffing, and (9) operating expenses paid to third parties. The
Trustees also reviewed information regarding the potential for the Fund and the
Investment Adviser to benefit from further economies of scale in the management
of the Fund in light of reasonable growth expectations for the Fund and certain
of the Fund's expenses that are not incurred as fees based on a percentage of
net assets.

The following summarizes matters considered by the Trustees in connection with
their renewal of the Fund's Management Contract. The Trustees did not identify
any single factor as all-important or controlling, and the summary does not
detail all the matters that were considered.

A.  Ancillary Benefits to Shareholders. The Trustees considered the benefits to
    shareholders of investing in a Fund that is part of a large number of
    investment companies offering a variety of investment disciplines and
    providing for a large variety of Fund and shareholder services.

                                                                              39

APPROVING THE MANAGEMENT CONTRACT                                    (continued)
- --------------------------------------------------------------------------------

B.  Compliance and Investment Performance. The Trustees determined that the
    Investment Adviser had policies and systems reasonably designed to achieve
    compliance with the Fund's investment objectives and regulatory
    requirements. The Trustees also reviewed the Fund's investment performance
    based upon total return and yield, as well as the Fund's performance
    compared to both the performance of a peer group and an index, in each case
    selected by the Independent Trustees for this purpose. The Fund's
    performance based upon total return was in the third quintile of the peer
    group for the 12 months ended June 30, 2004, the third quintile of the peer
    group for the three years ended June 30, 2004, and the third quintile for
    the five years ended June 30, 2004. (In all quintile rankings referred to
    throughout this discussion first quintile is most favorable to the Fund's
    shareholders. Thus, highest relative performance would be first quintile and
    lowest relative expenses also would be first quintile.) The Trustees also
    considered that the yield before expenses to Fund Class A shareholders (as
    of October 2004) exceeded the yield of the Standard & Poor's 500 Index. The
    Trustees concluded that the performance of the Fund supported the
    continuation of the Management Contract.

C.  The Investment Adviser's Personnel and Methods. The Trustees reviewed the
    background of members of the team responsible for the daily management of
    the Fund and the Fund's investment objective and discipline. The Independent
    Trustees also have had discussions with senior management of the Investment
    Adviser responsible for investment operations and the senior management of
    the Investment Adviser's equities group. Among other things, the Trustees
    considered the number, education and experience of the Investment Adviser's
    investment staff and their use of technology and emphasis on analytics in
    view of the risk profile of securities in which the Fund invests. The
    Trustees concluded that the Investment Adviser had the quality and depth of
    personnel and the well-developed methods essential to performing its duties
    under the Management Contract.

D.  Nature and Quality of Other Services. The Trustees considered the nature,
    quality, cost and extent of other services provided to shareholders of the
    Fund, including administrative and shareholder services performed by the
    Investment Adviser under the Management Contract. The Trustees also
    considered the reasonableness

40


Pioneer Equity Income Fund
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

    of the arrangements for reimbursement of the Investment Adviser's
    out-of-pocket costs and expenses, including overhead, for certain
    administrative services that the Investment Adviser is not required to
    provide under the Management Contract. The Trustees also considered the
    nature and extent of the other services provided by the Investment
    Adviser's affiliates under other contracts and its supervision of third
    party service providers. Based on these considerations, the Trustees
    concluded that the nature, quality, cost and extent of such services are
    satisfactory and reliable and serve the shareholders of the Fund well.

E.  Management Fee and Expenses. The Trustees considered the Investment
    Adviser's fee under the Management Contract relative to the management fees
    charged by a peer group of funds selected by the Independent Trustees for
    this purpose using data provided by an independent third party. The Fund's
    management fee for the 12 months ended June 30, 2004 was in the second
    quintile relative to the management fees paid by the other funds in that
    peer group for the comparable period. The Trustees determined that the fee
    under the Management Contract was reasonable and fair in light of both the
    overall nature and quality of services provided by the Investment Adviser
    and the fees charged by the funds in the peer group. The Trustees also
    considered the Fund's expense ratio and expense ratios of a peer group of
    funds selected by the Independent Trustees for this purpose. The Fund's
    expense ratio for the 12 months ended June 30, 2004 was in the second
    quintile of the applicable peer group for the most recent fiscal year of the
    peer group for the comparable period. The Trustees concluded that the Fund's
    overall expense ratio was lower than that of comparable funds.

F.  Profitability. The Trustees considered the level of the Investment Adviser's
    profits with respect to the management of the Pioneer Funds, including
    details with respect to the Fund. This consideration included a review of
    the Investment Adviser's methodology in allocating certain of its costs to
    the management of each Fund. The Trustees also considered the financial
    results realized by the Investment Adviser in connection with the operation
    of the Fund. They further considered the profits realized by the Investment
    Adviser and its affiliates from non-fund businesses that may benefit from or
    be related to the Fund's business. The Trustees considered the Investment
    Adviser's profit margins in comparison

                                                                              41

- --------------------------------------------------------------------------------

    with the limited available industry data. The Trustees concluded that the
    Investment Adviser's profits from management of the Pioneer Funds,
    including the financial results derived from the Fund, bear a reasonable
    relationship to the services rendered and are fair for the management of
    the Fund.

G.  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. Because of break points in
    the management fee, the Trustees concluded that any perceived or potential
    economies of scale would be shared at future asset levels in a reasonable
    manner as the Fund grows in size between Fund's shareholders and the
    Investment Adviser.

H.  Other Benefits to the Investment Adviser. The Trustees also considered the
    character and amount of fees paid by the Fund, other than under the
    Management Contract, for services provided by the Investment Adviser and
    affiliates, including fees for services such as shareholder services. The
    Trustees also considered the receipt of sales loads and payments under Rule
    12b-1 plans in respect to the Pioneer Funds (including the Fund), and
    benefits to the Investment Adviser from the use of "soft" commission dollars
    to pay for research and brokerage services. The Trustees further considered
    the revenues and profitability of the Investment Adviser's businesses other
    than the fund business, including the Investment Adviser's institutional
    investment advisory business. The Trustees considered the intangible
    benefits that accrue to the Investment Adviser and its affiliates by virtue
    of its relationship with the Fund and the Pioneer Funds as a group. The
    Trustees concluded that all these types of benefits accruing to the
    Investment Adviser were reasonable in the context of the overall
    relationship between the Investment Adviser and the Fund.

Conclusion. The Trustees, in light of the Investment Adviser's overall
performance, considered it appropriate to continue to retain the management
services of the Investment Adviser. Based on their evaluation of all material
factors deemed relevant and the advice of independent counsel, the Trustees
concluded that the Management Contract with the Fund is fair and reasonable and
voted to approve the continuation of the Management Contract for another year.

 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.

                 firm, the scope of the Audit

  performed with the exception of the(*)      services and related
  services that may be permitted              fees reported at each

- --------------------------------------------------------------------------------
GENERAL AUDIT COMMITTEE APPROVAL POLICY:
o For all projects, the officers of the Funds and the Fund's auditors will each
  make an assessment to determine that any proposed projects will not impair
  independence.

o Potential services will be classified into the four non-restricted service
  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy above will be applied. Any services outside the specific
  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

- --------------------------------------------------------------------------------


    (2) Disclose the percentage of services described in each of paragraphs (b)
   through (d) of this Item that were approved by the audit committee pursuant
   to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

    N/A

(f) If greater than 50 percent, disclose the percentage of hours expended on the
principal accountant's engagement to audit the registrant's financial statements
for the most recent fiscal year that were attributed to work performed by
persons other than the principal accountant's full-time, permanent employees.

N/A

(g) Disclose the aggregate non-audit fees billed by the registrant's accountant
for services rendered to the registrant, and rendered 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 for each of
the last two fiscal years of the registrant.

The Fund's independent auditor, Ernst & Young
LLP ("E&Y"), has advised the Securities
and Exchange Commission, the Public Company
Accounting Oversight Board, and the Audit
Committee of the Fund's Board of Trustees that
certain non-audit work performed by E&Y's China
affiliate raised questions regarding E&Y's
independence with respect to its performance of
audit services for the Fund.  In July 2004, E&Y
became aware that member firms in China ("E&Y
China") provided certain tax services to offices of
UniCredito Italiano, S.p.A. ("UCI"), a member of
the Fund's Investment Company Complex.  The
services included receipt and disbursement of
monies transferred to E&Y China by UCI in
payment of individual expatriate income taxes due
on returns prepared by E&Y China for certain UCI
employees located in China from October 1998 to
May 2003.  E&Y became auditors of the Fund in
May 2002.  These expatriate tax services were
discontinued in May 2003.  The fees received by
E&Y China for all such services totaled $3,685.

The Fund's Audit Committee and E&Y have
discussed the matter, including the nature of the
services provided, the personnel involved in
providing the services and the fees received by
E&Y for performing the services.  E&Y has informed
the Audit Committee that based on its internal reviews
and the de minimis nature of the services provided and
fees received, it does not believe its independence
with respect to the Fund has been impaired.

N/A


(h) Disclose whether the registrant's audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrant's investment adviser (not including any subadviser 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 investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.
