Dear Fellow Shareholders,

The stock market advanced for the second straight year, largely on the wings
of a strong post-election rally that produced solid returns for the major
indexes in 2004. For much of the year, the market was fairly dull, moving
mostly sideways as investors worried about higher interest rates,
sky-rocketing oil prices, the tight presidential election and the war in
Iraq. With the election over and oil prices moderating, investors felt more
confident, and the broad Standard & Poor's 500 Index wound up returning
10.88% for the year. The Dow Jones Industrial Average returned 5.40% and a
late and strong rally in technology stocks helped the Nasdaq Composite Index
move from a negative stance in October to finish the year with a 9.15%
return. Despite the Federal Reserve's five hikes in short-term interest
rates, bonds still turned in positive results, with the Lehman Brothers
Aggregate Bond Index up 4.34%.

The way this year has played out in the financial markets serves as a good
reminder of why keeping a long-term perspective is such a critical element
of successful investing. Getting caught up in the day-to-day twists and
turns of the market -- and trying to act on them -- can wreak havoc with
your portfolio and derail progress toward meeting your overall financial
objectives.

Since no one can predict the market's moves, the best way to reach your
goals is to stay invested and stick to your plan. Investing should be a
marathon, not a sprint. Do not try to time the market, and make sure you
work with your investment professional to ensure that your portfolio remains
properly diversified to meet your long-term objectives. For example, after
several years of dominance, small-cap stocks and value stocks could now
represent higher percentages of your portfolio than you may want. If you are
comfortable with your financial plan, it becomes easier to ride out the
market's daily ups and downs. It could also provide you with a greater
chance of success over time.

Sincerely,

/S/ JAMES A. SHEPHERDSON

James A. Shepherdson,
Chief Executive Officer

YOUR FUND
AT A GLANCE

The Fund seeks to
provide a high level
of after-tax total
return from divi-
dend income and
capital appreciation.
To meet its objec-
tives, the Fund
normally invests at
least 80% of its
assets in dividend-
paying common and
preferred securities
that the Adviser
believes are eligible
to pay dividends
that qualify for U.S.
taxation rates
applicable to long-
term capital gains,
which currently are
taxed at a maximum
rate of 15%.

Over the period

* Demand for high quality and high income fueled utility and financial
  common stocks, as well as preferred securities.

* Utility stocks performed best, as fundamental improvement lifted the
  group.

* Financial stocks were mixed due to varying conditions among subsectors.

MANAGERS'
REPORT

JOHN HANCOCK
Tax-Advantaged Dividend Income Fund

Utility and financial common stocks -- the two primary areas of emphasis of
John Hancock Tax-Advantaged Dividend Income Fund -- turned in impressive
results from the commencement of operations of the Fund on February 27, 2004
through December 31, 2004. Utility common stocks led the way, fueled by a
combination of the group's fundamental improvement -- evidenced by reduced
debt levels, improved balance sheets and the sale or closure of money-losing
unregulated subsidiaries -- and strong investor demand for high-quality
income-producing stocks. Investors' appetite for income also helped
financial stocks, although subsector returns were mixed. Regional banks,
diversified banks and real estate investment trusts (REITs) all performed
well, as investors sought more conservative safe-haven sectors with high
dividends and stable earnings throughout much of the period. Regional banks
also were bolstered by an upswing in mergers, while the more
market-sensitive names, such as trust banks and brokers, struggled until the
market's late-year rally. Many insurance stocks were hit hard toward the end
of the period by charges of bid rigging and price fixing against the most
prominent insurance broker, Marsh & McLennan. The performance of preferred
stocks -- a secondary focus of the Fund -- also was quite good during the
year, fueled in large measure by favorable supply and demand conditions.

"Utility and financial
 common stocks...turned in
 impressive results..."

Fund performance

From its commencement of operations on February 27, 2004 through December
31, 2004, John Hancock Tax-Advantaged Dividend Income Fund returned 12.85%
at net asset value and -5.47% at market value. The difference in the Fund's
net asset value (NAV) performance and its market performance stems from the
fact that the market share price is subject to the dynamics of secondary
market trading, which could cause it to trade at a discount or premium to
the Fund's NAV share price at any time.

Over the same period, the Standard & Poor's 500 Index returned 7.39% and the
average closed-end value fund returned 11.29% at net asset value, according
to Lipper, Inc.

Utility stocks shine

Many of our utility common stock holdings were our best performers for the
period. Among the best was NSTAR, the parent company of Boston Edison. The
company's stock benefited from a combination of favorable developments,
including the company's decision to increase its dividend and split its
stock, and its ability to continue to grow earnings, thanks to good cost
controls and robust economic conditions in its service territory. Public
Service Enterprise Group also performed well, thanks to a proposed takeover
by Exelon Corp., which propelled its stock price higher. The Fund also
enjoyed the strong returns posted by ONEOK, a diversified energy company
involved in oil and gas production, natural gas processing, gathering,
storage and transmission in the mid-continent areas of the United States. It
benefited from a well-executed business strategy and its ability to pass on
price increases in the wake of higher commodity prices. DTE Energy also
performed well, partly because of its attractive dividend and partly due to
the favorable resolution of a major utility rate case in its home state of
Michigan. Another top gainer was TECO Energy, buoyed by a combination of
above-average growth in its customer base and its ability to put the
problems associated with its merchant energy plants behind it.

"Many of our utility common stock
 holdings were our best performers
 for the period."

Merger banks boost results

Among our financial holdings, Bank of America, which merged with FleetBoston
late last year, was one of our top performers. The stock was buoyed by the
bank's ability to post solid earnings results, its announcement of a stock
split and a large increase in its quarterly dividends. Another merger stock
that did well was JPMorgan Chase, which acquired Bank One Corp. Regional
bank BB&T also posted strong gains as its above-average loan growth helped
it post record profits. On the flip side, headline and regulatory risk
worked against Citigroup, which had problems in several of its overseas
units.

Tax-advantaged securities lead preferred stock group

Given expectations that the 2003 tax reform bill would be made permanent
because of the re-election of President Bush and the larger Republican
majority in both the House and Senate, tax-advantaged preferred stocks were
in heavy demand and turned in good gains as a result during the period. One
example was Southern Union, which benefited from investors' expectations
that the company would receive a credit-rating upgrade. In the financial
sector, our preferred holdings in Bear Stearns did well thanks to the
combination of its attractive dividend and the strong financial performance
of the company.

Outlook

In our view, the late 2004 decline in oil prices and reports of better
economic data suggest that the Fed will continue on a measured path to raise
short-term interest rates. Although the rate hikes that were enacted
throughout 2004 haven't yet hurt the prices of preferred stocks, it's
possible that potentially higher long-term interest rates could dampen their
performance over the near term. As for utility stocks, we wouldn't be
altogether surprised if they are poised for a breather or even a pullback
over the short term given their rapid and recent impressive gains. Over the
longer term, however, there are a couple of factors we believe will continue
to work in favor of both preferred and utility common stocks. Making
permanent the recently reduced dividend tax rate and

strong demand from an aging American population potentially more intent
on shifting assets to high-quality income-producing securities should
provide some support for the group even if long-term bond yields rise. We
remain optimistic about the prospects for financial stocks. We expect the
group to navigate fairly well in a rising interest rate environment, and may
continue to see outperformance from the group if the economic recovery
remains sluggish.

 a couple of factors we believe will
 continue to work in favor of both
 preferred and utility common stocks."

NOTES TO
STATEMENTS

Note A
Accounting policies

John Hancock Tax-Advantaged Dividend Income Fund (the "Fund") is a
diversified closed-end management investment company registered under the
Investment Company Act of 1940.

Significant accounting policies
of the Fund are as follows:

Valuation of investments

Securities in the Fund's portfolio are valued on the basis of market
quotations, valuations provided by independent pricing services or at fair
value as determined in good faith in accordance with procedures approved by
the Trustees. Short-term debt investments which have a remaining maturity of
60 days or less may be valued at amortized cost, which approximates market
value. The Fund determines the net asset value of the common shares each
business day.

Investment transactions

Investment transactions are recorded as of the date of purchase, sale or
maturity. Net realized gains and losses on sales of investments are
determined on the identified cost basis.

Expenses

The majority of expenses are directly identifiable to an individual fund.
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 sizes of the funds.

Organization expense
and offering costs

Expenses incurred in connection with the organization of the Fund, which
amounted to $43,000, have been borne by the Fund. Offering costs of $854,726
related to common shares and offering costs of $396,310 incurred in
connection with the preferred shares were charged to the Fund's capital
paid-in.

Financial futures contracts

The Fund may buy and sell financial futures contracts. Buying futures tends
to increase the Fund's exposure to the underlying instrument. Selling
futures tends to decrease the Fund's exposure to the underlying instrument
or hedge other Fund's instruments. At the time the Fund enters into
financial futures contracts, it is required to deposit with its custodian a
specified amount of cash or U.S. government securities, known as "initial
margin," equal to a certain percentage of the value of the financial futures
contract being traded. Each day, the futures contract is valued at the
official settlement price of the board of trade or U.S. commodities exchange
on which it trades. Subsequent payments to and from the broker, known as
"variation margin," are made on a daily basis as the market price of the
financial futures contract fluctuates. Daily variation margin


16



adjustments arising from this "mark to market" are recorded by the Fund as
unrealized gains or losses.

When the contracts are closed, the Fund recognizes a gain or loss. Risks of
entering into financial futures contracts include the possibility that there
may be an illiquid market and/or that a change in the value of the contracts
may not correlate with changes in the value of the underlying securities. In
addition, the Fund could be prevented from opening or realizing the benefits
of closing out financial futures positions because of position limits or
limits on daily price fluctuation imposed by an exchange.

For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of financial futures
contracts. On December 31, 2004, the Fund had deposited $212,500 in a
segregated account to cover margin requirements on open financial futures
contracts.

The Fund had the following financial futures contracts open on December 31,
2004:

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.

Dividends, interest
and distributions

Dividend income on investment securities is recorded on the ex-dividend date
or, in the case of some foreign securities, on the date thereafter when the
Fund iden ti fies the dividend. Interest income on investment securities is
recorded on the accrual basis. Foreign income may be subject to foreign
withholding taxes, which are accrued as applicable.

The Fund records distributions to shareholders from net investment income
and net realized gains, if any, on the ex-dividend date. For the year ended
December 31, 2004, the tax character of distributions paid was as follows:
ordinary income $40,984,036. As of December 31, 2004, the components of
distributable earnings on a tax basis included $2,958,880 of undistributed
ordinary income.

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.

Use of estimates

The preparation of these financial statements, in accordance with accounting
principles generally accepted in the United States of America, incorporates
estimates made by management in determining the reported amount of assets,
liabilities, revenues and expenses of the Fund. Actual results could differ
from these estimates.

Note B
Management fee and
transactions with
affiliates and others

The Fund has an investment management contract with John Hancock Advisers,
LLC (the"Adviser"), a wholly owned subsidiary of John Hancock Financial
Services, Inc. Under the investment


17



management contract, the Fund pays a daily management fee to the Adviser
at an annual rate of 0.75% of the Fund's average daily net asset value and
the value attributable to the Auction Preferred Shares (collectively,
"managed assets").

The Adviser has contractually agreed to limit the Fund's management fee to
the following: 0.55% of the Fund's average daily managed assets until the
fifth anniversary of the commencement of the Fund's operations, 0.60% of
such assets in the sixth year, 0.65% of such assets in the seventh year and
0.70% of average daily managed assets in the eighth year. Accord ingly, the
expense reductions related to the reduction in the management fee amounted
to $1,827,851 for the period ended December 31, 2004. After the eighth year,
the Adviser will no longer waive a portion of the management fee.

The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the
period amounted to $231,890. The Fund also paid the Adviser the amount of
$116 for certain publishing services, included in the printing fees.

Mr. James A. Shepherdson is a director and officer of the Adviser, as well
as affiliated Trustee of the Fund, and is compensated by the Adviser. 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 Compen
sation 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.

2 Net of $0.90 per share sales load of the initial offering price of $20.00

18



Auction preferred shares

The Fund issued a total of 15,200 Auction Preferred Shares (3,800 shares of
Series M, 3,800 shares of Series W, 3,800 of shares of Series TH and 3,800
shares of Series F) (collectively, the "APS") on May 3, 2004, in a public
offering. The underwriting discount of $3,800,000 has been charged to
capital paid-in of common shares.

Dividends on the APS, which accrue daily, are cumulative at a rate that was
established at the offering of the APS and has been reset every 7 days
thereafter by an auction (except for the Series TH, which reset its rate on
October 28, 2004, at which time the Fund elected a Special Dividend Payment
of 182 days for the subsequent distributions). Dividend rates on APS ranged
from 1.15% to 2.70% during the period ended December 31, 2004. Accrued
dividends on APS are included in the value of APS on the Fund's Statement of
Assets and Liabilities.

The APS are redeemable at the option of the Fund, at a redemption price
equal to $25,000 per share, plus accumulated and unpaid dividends on any
dividend payment date. The APS are also subject to mandatory redemption at a
redemption price equal to $25,000 per share, plus accumulated and unpaid
dividends, if the Fund is in default on its asset coverage requirements with
respect to the APS as defined in the Fund's by-laws. If the dividends on the
APS shall remain unpaid in an amount equal to two full years' dividends, the
holders of the APS, as a class, have the right to elect a majority of the
Board of Trustees. In general, the holders of the APS and the common
shareholders have equal voting rights of one vote per share, except that the
holders of the APS, as a class, vote to elect two members of the Board of
Trustees, and separate class votes are required on certain matters that
affect the respective interests of the APS and common shareholders.

Note D
Investment
transactions

Purchases and proceeds from sales or maturities of securities, other than
short-term securities and obligations of the U.S. government, during the
period ended December 31, 2004, aggregated $1,554,572,324 and $396,748,061,
respectively.

The cost of investments owned on December 31, 2004, including short-term
investments, for federal income tax purposes, was $1,183,551,089. Gross
unrealized appreciation and depreciation of investments aggregated
$83,308,596 and $22,937,881, respectively, resulting in net unrealized
appreciation of $60,370,715. The difference between book basis and tax basis
net unrealized appreciation of investments is attributable primarily to the
tax deferral of losses on certain sales of securities.

Note E
Reclassification
of accounts

During the period ended December 31, 2004, the Fund reclassified amounts to
reflect an increase in accumulated net realized loss on investments of
$686,137, and an increase in distributions in excess of net investment
income of $686,137. This represents the amounts necessary to report these
balances on a tax basis, excluding certain temporary differences, as of
December 31, 2004. Additional adjustments may be needed in subsequent
reporting periods. These reclassifications, which have no impact on the net
asset value of the Fund, are primarily attributable to certain differences
in the computation of distributable income and capital gains under federal
tax rules versus accounting principles generally accepted in the United
States of America and book and tax differences in accounting for deferred
compensation. The calculation of net investment income per share in the
Fund's Financial Highlights excludes these adjustments.

AUDITORS'
REPORT

Report of Deloitte
& Touche LLP,
Independent
Registered Public
Accounting Firm

To Board of Trustees and the Shareholders of
John Hancock Tax-Advantaged Dividend Income Fund

We have audited the accompanying statement of assets and liabilities of
John Hancock Tax-Advantaged Dividend Income Fund (the "Fund"), including
the schedule of investments, as of December 31, 2004, and the related
statements of operations, the statement of changes in net assets and the
financial highlights for the period from the commencement of operations on
February 27, 2004 through December 31, 2004. 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 audit.

We conducted our audit in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require
that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements and financial highlights are free of
material misstatement. An audit includes 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, assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of December 31, 2004, by correspondence with the
custodian and brokers; where replies were not received from brokers, we
performed other auditing procedures. We believe that our audit provides 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
John Hancock Tax-Advantaged Dividend Income Fund as of December 31, 2004,
the results of its operations, the changes in its net assets and the
financial highlights for the period from the commencement of operations
February 27, 2004 through December 31, 2004, in conformity with accounting
principles generally accepted in the United States of America.

TAX
INFORMATION

Unaudited

For federal income tax purposes, the following information is furnished with
respect to the distributions of the Fund, if any, paid during its taxable
year ended December 31, 2004.

With respect to the ordinary dividends paid by the Fund for the fiscal year
ended December 31, 2004, 97.84% of the dividends qualifies for the corporate
dividends-received deduction.

The Fund hereby designates the maximum amount allowable of its net taxable
income as qualified dividend income as provided in the Jobs and Growth Tax
Relief Reconciliation Act of 2003. This amount will be reflected on Form
1099-DIV for the calendar year 2004.

Shareholders will be mailed a 2004 U.S. Treasury Department Form 1099-DIV in
January 2005. This will reflect the total of all distributions that are
taxable for the calendar year 2004.


21



Investment
objective
and policy

The Fund's investment objective is to provide a high level of after-tax
total return from dividend income and capital appreciation.

Under normal market conditions, the Fund will invest at least 80% of its
assets (net assets plus borrowings for investment purposes) in
dividend-paying common and preferred securities that the Adviser believes
at the time of acquisition are eligible to pay dividends which, for
individual shareholders, qualify for U.S. federal income taxation at rates
applicable to long-term capital gains, which currently are taxed at a
maximum rate of 15% ("tax-advantaged dividends"). Tax-advantaged dividends
generally include dividends from domestic corporations and dividends from
foreign corporations that meet certain specified criteria. The Fund
generally can pass the tax treatment of tax-advantaged dividends it
receives through to its common shareholders.

Dividend
reinvestment plan

The Fund offers its shareholders a Dividend Reinvestment Plan (the "Plan"),
which offers the opportunity to earn compounded yields. Each holder of
common shares will automatically have all distributions of dividends and
capital gains reinvested by Mellon Investor Services, as Plan Agent for the
common shareholders (the "Plan Agent"), unless an election is made to
receive cash. Holders of common shares who elect not to participate in the
Plan will receive all distributions in cash, paid by check and mailed
directly to the shareholder of record (or, if the common shares are held in
street or other nominee name, then to the nominee) by the Plan Agent, as
dividend-disbursing agent. Shareholders whose shares are held in the name of
a broker or a nominee should contact the broker or nominee to determine
whether and how they may participate in the Plan.

If the Fund declares a dividend payable either in common shares or in cash,
non-participants will receive cash and participants in the Plan will receive
the equivalent in common shares. If the market price of the common shares on
the payment date of the dividend is equal to, or exceeds, their net asset
value as determined on the payment date, participants will be issued common
shares (out of authorized but unissued shares) at a value equal to the
higher of net asset value or 95% of the market price. If the net asset value
exceeds the market price of the common shares at such time, or if the Board
of Trustees declares a dividend payable only in cash, the Plan Agent will,
as agent for Plan participants, buy shares in the open market, on the New
York Stock Exchange or elsewhere, for the participants' accounts. Such
purchases will be made promptly after the payable date for such dividend
and, in any event, prior to the next ex-dividend date after such date,
except where necessary to comply with federal securities laws. If, before
the Plan Agent has completed its purchases, the market price exceeds the net
asset value of the common shares, the average per share purchase price paid
by the Plan Agent may exceed the net asset value of the common shares,
resulting in the acquisition of fewer shares than if the dividend had been
paid in shares issued by the Fund.

Each participant will pay a pro rata share of brokerage commissions incurred
with respect to the Plan Agent's open market purchases in connection with
the reinvestment of dividends and distributions. The cost per share of the
shares purchased for each participant's account will be the average cost,
including brokerage commissions, of any shares purchased on the open market,
plus the cost of any shares issued by the Fund. There will be no brokerage
charges with respect to common shares issued directly by the Fund. There are
no other charges to participants for reinvesting dividends or capital gain
distributions.


22



Participants in the Plan may withdraw from the Plan at any time by
contacting the Plan Agent by telephone, in writing or by visiting the Plan
Agent's Web site at www.melloninvestor.com. Such withdrawal will be
effective immediately if received not less than ten days prior to a dividend
record date; otherwise, it will be effective for all subsequent dividend
record dates. When a participant withdraws from the Plan or upon termination
of the Plan, as provided below, certificates for whole common shares
credited to his or her account under the Plan will be issued and a cash
payment will be made for any fraction of a share credited to such account.

The Plan Agent maintains each shareholder's account in the Plan and
furnishes monthly written confirmations of all transactions in the accounts,
including information needed by the shareholders for personal and tax
records. The Plan Agent will hold common shares in the account of each Plan
participant in non-certificated form in the name of the participant. Proxy
material relating to the shareholders' meetings of the Fund will include
those shares purchased, as well as shares held pursuant to the Plan.

The reinvestment of dividends and distributions will not relieve
participants of any federal income tax that may be payable or required to be
withheld on such dividends or distributions. Participants under the Plan
will receive tax information annually. The amount of dividend to be reported
on the 1099-DIV should be: (1) in the case of shares issued by the Fund, the
fair market value of such shares on the dividend payment date and (2) in the
case of shares purchased by the Plan Agent in the open market, the amount of
cash used by the Plan Agent to purchase shares in the open market, including
the amount of cash allocated to brokerage commissions paid on such
purchases.

Experience under the Plan may indicate that changes are desirable.
Accordingly, the Fund reserves the right to amend or terminate the Plan as
applied to any dividend or distribution paid subsequent to written notice of
the change sent to all shareholders of the Fund at least 90 days before the
record date for the dividend or distribution. The Plan may be amended or
terminated by the Plan Agent after at least 90 days' written notice to all
shareholders of the Fund. All correspondence or additional information
concerning the Plan should be directed to the Plan Agent, Mellon Bank, N.A.,
c/o Mellon Investor Services, P.O. Box 3338, South Hackensack, NJ 07606-1938
(telephone 1-800-852-0218).

ITEM 2.  CODE OF ETHICS.

As of the end of the period, December 31, 2004, 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
$32,850 for the fiscal year ended December 31, 2004, the Fund's first year
in operation (commenced operations on February 26, 2005). 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 December 31,
2004 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 $2,250 for the fiscal year ended December 31,
2004. 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

The all other fees billed to the registrant for products and services
provided by the principal accountant were $4,000 for the fiscal year ended
December 31, 2004. There were no other fees during the fiscal year ended
December 31, 2004 billed to control affiliates for products and services
provided by the principal accountant. The nature of the services comprising
the all other fees was related to the principal accountant's report on the
registrant's Eligible Asset Coverage. These fees were approved by the
registrant's audit committee.

(e)(1) See attachment "Approval of Audit, Audit-related, Tax and Other
Services", with the audit committee pre-approval policies and procedures.

(e)(2) There were no fees that were approved by the audit committee
pursuant to the de minimis exception for the fiscal year ended December 31,
2004 on behalf of the registrant or on behalf of the control affiliates
that relate directly to the operations and financial reporting of the
registrant.

(f) According to the registrant's principal accountant, for the fiscal year
ended December 31, 2004, 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 the fiscal year of the registrant were $71,250 for
the fiscal year ended December 31, 2004.

(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.
