NAV per share is determined by dividing the value of the trust's portfolio
securities, cash and other assets, less all liabilities, by the total number of
common shares outstanding. The common share market price is the price the market
is willing to pay for shares of the trust at a given time. Common share market
price is influenced by a range of factors, including supply and demand and
market conditions. Total return assumes an investment at the beginning of the
period, reinvestment of all distributions for the period in accordance with the
trust's dividend reinvestment plan, and sale of all shares at the end of the
period.

The Lehman Brothers Municipal Bond Index is a broad-based statistical composite
of municipal bonds. The index does not include any expenses, fees or sales
charges, which would lower performance. The index is unmanaged and should not be
considered an investment. It is not possible to invest directly in an index.

Trust Report

FOR THE 12-MONTH PERIOD ENDED OCTOBER 31, 2004

Van Kampen Strategic Sector Municipal Trust is managed by the Adviser's
Municipal Fixed Income team.(1) Current members include Timothy D. Haney, Vice
President; Robert Wimmel, Vice President; and John Reynoldson, Executive
Director.

MARKET CONDITIONS

The interest-rate environment of the 12 months ended October 31, 2004 was marked
by two periods of steadily declining yields, with a significant sell-off in the
middle. Yields fell steadily through the first half of the period, approaching
the historical lows of 2003. This trend persisted until March, at which point
yields reversed direction and began an upward march as prices fell. These losses
were steepest in April, as a surprisingly strong employment report and signals
from members of the Federal Open Market Committee (the Fed) caused investors to
expect a near-term rate increase. Rates went on to decline from May through the
end of the period as the market digested the Fed's newly hawkish rate stance.
Investors were further comforted when, after the Fed raised rates at its June
30, 2004 meeting, its members indicated that the path of future rate increases
would be measured.

Unusually, longer-maturity securities largely outperformed in this period of Fed
tightening. Historically, the typical pattern in periods of tightening policy
has seen yields rise across all maturities. During the review period, however,
yields of shorter maturity bonds rose while those of bonds with longer
maturities declined slightly.

Lower-quality municipal bonds also performed strongly in this environment, as
the difference in yields (known as the "yield spread") between AAA and BBB rated
bonds decreased by roughly 20 basis points for 20-year bonds. As a result,
sectors with heavy exposure to lower-rated debt, such as hospitals and
industrial revenue bonds, posted higher total returns than sectors dominated by
higher-rated debt.

Issuance for the first ten months of 2004 (the final ten months of the review
period) was roughly six percent lower than in the same period in 2003. That
said, 2003 was a record year, and at the current pace of issuance, 2004 could
well be one of the largest years in recent memory. The strong supply met with
faltering demand from mutual funds, as fund investors withdrew over $15 billion
in net cash during the period. This faltering demand was largely offset by
increased participation in the market by insurance companies and individual
investors.

PERFORMANCE ANALYSIS

The trust's return can be calculated based upon either the market price or the
net asset value (NAV) of its shares. NAV per share is determined by dividing the
value of the trust's portfolio securities, cash and other assets, less all
liabilities, by the total number of common shares outstanding, while market
price reflects the supply and demand for the shares. As a result, the two
returns can differ significantly, as they did during the reporting period. On an
NAV basis, the trust outperformed its benchmark, the Lehman Brothers Municipal
Bond Index. (See table below.)

The trust uses leverage to enhance its dividend to common shareholders. The
trust borrows money at short-term rates through the issuance of preferred
shares. The proceeds are reinvested in longer-term securities, taking advantage
of the difference between short- and longer-term rates. The Fed's policy of
raising interest rates in the final months of the period made the trust's
borrowing activity more expensive. These expenses, however, were more than
offset by the strong performance of the bonds we invested in, leading to the
trust's outperformance versus its benchmark, which is unleveraged.

One of our primary strategies in managing the trust was to configure its
interest-rate profile for a rising interest rate environment. We did this
primarily by maintaining its duration (a measure of interest-rate sensitivity)
at a level lower than that of its benchmark. We also de-emphasized securities
with maturities in the range of five-to-10 years given what appeared to be
unattractive total-return prospects. Instead, we emphasized securities in the
15- to 20-year part of the yield curve. Many of the securities we purchased
offered a compelling combination of premium-coupon income and the moderate
interest-rate sensitivity of bonds with shorter maturities. While the overall
duration strategy provided mixed results, the portfolio's positioning along the
maturity spectrum boosted performance for the period.

In keeping with our long-term approach, we continued to engage in relative-
value trading in order to take advantage of pockets of opportunity in the
market. This approach generally entails buying securities that are undervalued
relative to what our analysis indicates to be their total-return potential, and

selling them when they reach that potential in order to reinvest the assets into
more promising opportunities. We took advantage of the late spring/early summer
spike in yields to purchase long bonds which we later sold during a period of
strong demand from individual investors. We also selectively purchased several
BBB rated securities, some of which we subsequently sold at a profit thanks to
investors' demand for yield-oriented securities. The trust saw significant bond
call activity during the period. As we reinvested these monies, we maintained a
conservative duration profile by trimming the trust's holdings of zero coupon
bonds, which are highly rate sensitive.

We remained focused on controlling the trust's risk profile through attention to
credit quality and diversification. By the end of the 12-month period, nearly 85
percent of the trust's total investments were invested in bonds rated AAA and
AA; these represent the two highest tiers of credit ratings. The portfolio was
also well diversified across the major sectors of the municipal bond market. Its
three largest sector exposures were general purpose, public building, and
industrial revenue.

While it is impossible to predict the exact turning point when interest rates
will move decisively higher, we believe the trust remains well positioned for
the near future. We will continue to comb the municipal bond markets for
interesting opportunities.

There is no guarantee that any securities will continue to perform well or be
held by the trust in the future.

VAN KAMPEN STRATEGIC SECTOR MUNICIPAL TRUST

NOTES TO FINANCIAL STATEMENTS -- OCTOBER 31, 2004

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Strategic Sector Municipal Trust (the "Trust") is registered as a
non-diversified, closed-end management investment company under the Investment
Company Act of 1940 (the "1940 Act"), as amended. The Trust's investment
objective is to seek to provide a high level of current income exempt from
federal income tax, consistent with preservation of capital. The Trust will
invest in a portfolio consisting substantially of municipal obligations from
those market sectors which the Adviser feels will best meet the Trust's
investment objective. The Trust commenced investment operations on January 22,
1993. Effective November 30, 2003, the Trust's investment adviser, Van Kampen
Investment Advisory Corp. merged into its affiliate, Van Kampen Asset Management
(the "Adviser").

    The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Futures contracts are valued at the settlement price established each day on the
exchange on which they are traded. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost, which approximates
market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Trust may purchase and sell securities on a "when-issued" or "delayed delivery"
basis with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Trust will
segregate assets with the custodian having an aggregate value at least equal to
the amount of the when-issued or delayed delivery purchase commitments until
payment is made. At October 31, 2004, the Trust had $8,040,300 of when-issued
and delayed delivery purchase commitments.

C. INVESTMENT INCOME Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security.

D. FEDERAL INCOME TAXES It is the Trust's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

    The Trust intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At October 31, 2004, the Trust had an

E. DISTRIBUTION OF INCOME AND GAINS The Trust declares and pays monthly
dividends from net investment income to common shareholders. Net realized gains,
if any, are distributed annually on a pro rata basis to common and preferred
shareholders. Distributions from net realized gains for book purposes may
include short-term capital gains and a portion of futures gains, which are
included as ordinary income for tax purposes.

    The tax character of distributions paid during the years ended October 31,
2004 and 2003, was as follows:

                                                                2004       2003

                                                              $909,785    $41,136

</Table>

    Due to inherent differences in the recognition of income, expenses and
realized gains/losses under accounting principles generally accepted in the
United States of America and federal income tax purposes, permanent differences
between book and tax basis reporting have been identified and appropriately
reclassified on the Statement of Assets and Liabilities. A permanent book and
tax difference relating to a portion of the capital loss carryforward expiring
in the current year totaling $863,153 was reclassified from accumulated net
realized loss to paid in surplus. Additionally, a permanent book and tax
difference relating to excise taxes paid which are not deductible for tax
purposes totaling $2,839 was reclassified from accumulated net investment income
to paid in surplus. Also, a permanent book and tax difference relating to book
and tax accretion differences totaling $36,739 was reclassified from accumulated
undistributed net investment income to accumulated net realized loss.

    As of October 31, 2004, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                           
Undistributed ordinary income...............................  $556,810
</Table>

    Net realized gains and losses may differ for financial reporting and tax
purposes primarily as a result of gains and losses recognized for tax purposes
on open future contracts on October 31, 2004.

                                                                              21

NOTES TO FINANCIAL STATEMENTS -- OCTOBER 31, 2004 continued

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Trust's Investment Advisory Agreement, the Adviser
provides investment advice and facilities to the Trust for an annual fee payable
monthly of .60% of the average daily net assets of the Trust. Effective June 1
and November 1, 2004, the investment advisory fee was reduced from .65% to .60%
and from .60% to .55%, respectively. In addition, the Trust paid a monthly
administrative fee to Van Kampen Investments Inc. or its affiliates'
(collectively "Van Kampen"), the Trust's Administrator, at an annual rate of
..10% of the average daily net assets of the Trust. Effective June 1, 2004, the
administrative fees were reduced from .10% to .00%, respectively.

    For the year ended October 31, 2004, the Trust recognized expenses of
approximately $14,800 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to the Trust, of which a trustee of the Trust
is a partner who provides legal services to the Trust, and is therefore an
affiliated person.

    Under separate Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Trust. The Adviser
allocates the cost of such services to each trust. For the year ended October
31, 2004, the Trust recognized expenses of approximately $31,800 representing
Van Kampen's cost of providing accounting and legal services to the Trust, which
are reported as part of "Other" and "Legal" expenses, respectively, in the
Statement of Operations.

    Certain officers and trustees of the Trust are also officers and directors
of Van Kampen. The Trust does not compensate its officers or trustees who are
also officers of Van Kampen.

    The Trust provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation to a
later date. Benefits under the retirement plan are payable upon retirement for a
ten-year period and are based upon each trustee's years of service to the Trust.
The maximum annual benefit per trustee under the plan is $2,500.

3. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $98,547,923 and $96,469,212,
respectively.

4. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

    In order to seek to manage the interest rate exposure of the Trust's
portfolio in a changing interest rate environment, the Trust may purchase or
sell financial futures contracts or engage in transactions involving interest
rate swaps, caps, floors or collars. The Trust expects to enter into these
transactions primarily as a hedge against anticipated interest rate or
fixed-income market changes, for duration management or for risk management
purposes, but may also enter into these transactions to generate additional
income. All of the Trust's portfolio holdings, including derivative instruments,
are marked to market each day with the change in value reflected in the
unrealized appreciation/depreciation. Upon disposition, a realized gain or loss
is recognized accordingly, except when taking delivery of a security underlying
a futures contract. In this instance, the recognition of gain or loss is
postponed until the disposal of the security underlying the futures contract.

 22


VAN KAMPEN STRATEGIC SECTOR MUNICIPAL TRUST

NOTES TO FINANCIAL STATEMENTS -- OCTOBER 31, 2004 continued

    During the period, the Trust invested in futures contracts, a type of
derivative. A futures contract is an agreement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Trust
generally invests in exchange traded futures on U.S. Treasury Bonds and Notes
and typically closes the contract prior to delivery date. Upon entering into
futures contracts, the Trust maintains an amount of cash or liquid securities
with a value equal to a percentage of the contract amount with either a future
commission merchant pursuant to rules and regulations promulgated under the 1940
Act, as amended, or with its custodian in an account in the broker's name. This
amount is known as initial margin. During the period the futures contract is
open, payments are received from or made to the broker based upon changes in the
value of the contract (the variation margin). The risk of loss associated with a
futures contract is in excess of the variation margin reflected on the Statement
of Assets and Liabilities.

    Transactions in futures contracts for the year ended October 31, 2004, were
as follows:

5. PREFERRED SHARES

The Trust has outstanding 3,800 Auction Preferred Shares ("APS") in two series.
Series A contains 2,000 shares while Series B contains 1,800 shares. Dividends
are cumulative and the dividend rate for both Series is generally reset every 28
days through an auction process. At October 31, 2004, the average rate in effect
was 1.653%. During the year ended October 31, 2004, the rates ranged from 0.790%
to 1.700%.

    The Trust pays annual fees equivalent to .25% of the preferred share
liquidation value for the remarketing efforts associated with the preferred
auctions. These fees are included as a component of "Preferred Share
Maintenance" expense in the Statement of Operations.

    The APS are redeemable at the option of the Trust in whole or in part at the
liquidation value of $25,000 per share plus accumulated and unpaid dividends.
The Trust is subject to certain asset coverage tests and the APS are subject to
mandatory redemption if the tests are not met.

                                                                              23

6. INDEMNIFICATIONS

The Trust enters into contracts that contain a variety of indemnification. The
Trust's maximum exposure under these arrangements is unknown. However, the Trust
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

VAN KAMPEN STRATEGIC SECTOR MUNICIPAL TRUST

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of Van Kampen Strategic Sector
Municipal Trust:

We have audited the accompanying statement of assets and liabilities of Van
Kampen Strategic Sector Municipal Trust (the "Trust"), including the portfolio
of investments, as of October 31, 2004, the related statement of operations for
the year then ended, the statements of changes in net assets for each of the two
years in the period then ended, and the financial highlights for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the Trust's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits. The Trust's financial highlights for the periods ended
prior to October 31, 2000 were audited by other auditors whose report, dated
December 6, 1999, expressed an unqualified opinion on those financial
highlights.

    We conducted our audits in accordance with standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004, by correspondence with the Trust's
custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of Van
Kampen Strategic Sector Municipal Trust as of October 31, 2004, the results of
its operations for the year then ended, the changes in its net assets and the
financial highlights for the respective stated periods, in conformity with
accounting principles generally accepted in the United States of America.

VAN KAMPEN STRATEGIC SECTOR MUNICIPAL TRUST

DIVIDEND REINVESTMENT PLAN

    The Trust offers a Dividend Reinvestment Plan (the "Plan") pursuant to which
Common Shareholders who are participants in the Plan may have dividends and
capital gains distributions automatically reinvested in Common Shares of the
Trust. All Common Shareholders are deemed to be participants in the Plan unless
they specifically elect not to participate. Common Shareholders who elect not to
participate in the Plan will receive all distributions of dividends and capital
gains in cash paid by check mailed directly to the Common Shareholder by the
Trust's dividend disbursing agent.

HOW THE PLAN WORKS

    State Street Bank and Trust Company, as your Plan Agent, serves as agent for
the Common Shareholders in administering the Plan. After the Trust declares a
dividend or determines to make a capital gains distribution, the Plan Agent
will, as agent for the participants, receive the cash payment and use it to buy
Common Shares in the open market, on the New York Stock Exchange or elsewhere,
for the participants' accounts. The Trust will not issue any new Common Shares
in connection with the Plan. All reinvestments are in full and fractional Common
Shares, carried to three decimal places.

    Experience under the Plan may indicate that changes are desirable.
Accordingly, the Trust 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 Common Shareholders of the Trust at least 90 days before the
record date for the dividend or distribution. The Plan also may be amended or
terminated by the Plan Agent by at least 90 days written notice to all Common
Shareholders of the Trust.

COSTS OF THE PLAN

    The Plan Agent's fees for the handling of the reinvestment of dividends and
distributions will be paid by the Trust. However, 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. No other charges will be made to participants for reinvesting
dividends or capital gains distributions, except for certain brokerage
commissions, as described above.

TAX IMPLICATIONS

    You will receive tax information annually for your personal records and to
help you prepare your federal income tax return. The automatic reinvestment of
dividends and capital gains distributions does not relieve you of any income tax
which may be payable on dividends or distributions.

RIGHT TO WITHDRAW

    All Common Shareholders of the Trust are deemed to be participants in the
Plan unless they specifically elect not to participate. You may withdraw from
the Plan at any time by calling 1-800-341-2929 or by writing State Street Bank
and Trust Company, P.O. Box 8200, Boston, MA 02266-8200. If you withdraw, you
will receive, without charge, a share certificate issued in your name for all
full Common Shares credited to your account under the Plan and a cash payment
will be made for any fractional Common Share credited to your account under the
Plan. You may again elect to participate in the Plan at any time by calling

Item 2. Code of Ethics.

(a) The Trust has adopted a code of ethics (the "Code of Ethics") that applies

regardless of whether these individuals are employed by the Trust or a third
party.

(b) No information need be disclosed pursuant to this paragraph.

shareholder report presented in Item 1 hereto to delete from the end of the
following paragraph on page 2 of the Code the phrase "to the detriment of the
Fund.":

"Each Covered Officer must not use his personal influence or personal
relationship improperly to influence investment decisions or financial reporting
by the Fund whereby the Covered Officer would benefit personally (directly or
indirectly)."

Item 3. Audit Committee Financial Expert.

The Trust's Board of Trustees has determined that it has three "audit committee
financial experts" serving on its audit committee, each of whom are
"independent" Trustees : J. Miles Branagan, Jerry Choate and R. Craig Kennedy.
Under applicable securities laws, a person who is determined to be an audit
committee financial expert will not be deemed an "expert" for any purpose,
including without limitation for the purposes of Section 11 of the Securities
Act of 1933, as a result of being designated or identified as an audit committee
financial expert. The designation or identification of a person as an audit
committee financial expert does not impose on such person any duties,
obligations, or liabilities that are greater than the duties, obligations, and
liabilities imposed on such person as a member of the audit committee and Board
of Trustees in the absence of such designation or identification.

(e)(1) The audit committee's pre-approval policies and procedures are as

                              JOINT AUDIT COMMITTEE
                          AUDIT AND NON-AUDIT SERVICES
                       PRE-APPROVAL POLICY AND PROCEDURES
                                     OF THE
                                VAN KAMPEN FUNDS

              AS ADOPTED JULY 23, 2003 AND AMENDED MAY 26, 2004(1)

1.    STATEMENT OF PRINCIPLES

      The Audit Committee of the Board is required to review and, in its sole
discretion, pre-approve all Covered Services to be provided by the Independent
Auditors to the Fund and Covered Entities in order to assure that services
performed by the Independent Auditors do not impair the auditor's independence
from the Fund.(2)

      The SEC has issued rules specifying the types of services that an
independent auditor may not provide to its audit client, as well as the audit
committee's administration of the engagement of the independent auditor. The
SEC's rules establish two different approaches to pre-approving services, which
the SEC considers to be equally valid. Proposed services either: may be
pre-approved without consideration of specific case-by-case services by the
Audit Committee ("general pre-approval"); or require the specific pre-approval
of the Audit Committee ("specific pre-approval"). The Audit Committee believes
that the combination of these two approaches in this Policy will result in an
effective and efficient procedure to pre-approve services performed by the
Independent Auditors. As set forth in this Policy, unless a type of service has
received general pre-approval, it will require specific pre-approval by the
Audit Committee (or by any member of the Audit Committee to which pre-approval
authority has been delegated) if it is to be provided by the Independent
Auditors. Any proposed services exceeding pre-approved cost levels or budgeted
amounts will also require specific pre-approval by the Audit Committee.

      For both types of pre-approval, the Audit Committee will consider whether
such services are consistent with the SEC's rules on auditor independence. The
Audit Committee will also consider whether the Independent Auditors are best
positioned to provide the most effective and efficient services, for reasons
such as its familiarity with the Fund's business, people, culture, accounting
systems, risk profile and other factors, and whether the service might enhance
the Fund's ability to manage or control risk or improve audit quality. All such
factors will be considered as a whole, and no one factor should necessarily be
determinative.

      The Audit Committee is also mindful of the relationship between fees for
audit and non-audit services in deciding whether to pre-approve any such
services and may determine for each fiscal year, the appropriate ratio between
the total amount of fees for Audit, Audit-related and Tax services for the Fund
(including any Audit-related or Tax service fees for Covered Entities that were
subject to pre-approval), and the total amount of fees for certain permissible
non-audit services classified as All Other services for the Fund (including any
such services for Covered Entities subject to pre-approval).

      The appendices to this Policy describe the Audit, Audit-related, Tax and
All Other services that have the general pre-approval of the Audit Committee.
The term of any general pre-approval is 12 months from the date of pre-approval,
unless the Audit Committee considers and provides a different period and states
otherwise. The Audit Committee will annually review and pre-approve the services
that may be provided by the Independent Auditors without obtaining specific
pre-approval

- -------------------------
(1)   This Joint Audit Committee Audit and Non-Audit Services Pre-Approval
      Policy and Procedures (the "Policy"), amended as of the date above,
      supercedes and replaces all prior versions that may have been amended from
      time to time.

(2)   Terms used in this Policy and not otherwise defined herein shall have the
      meanings as defined in the Joint Audit Committee Charter.



from the Audit Committee. The Audit Committee will add to or subtract from the
list of general pre-approved services from time to time, based on subsequent
determinations.

      The purpose of this Policy is to set forth the policy and procedures by
which the Audit Committee intends to fulfill its responsibilities. It does not
delegate the Audit Committee's responsibilities to pre-approve services
performed by the Independent Auditors to management.

      The Fund's Independent Auditors have reviewed this Policy and believes
that implementation of the Policy will not adversely affect the Independent
Auditors' independence.

2.    DELEGATION

      As provided in the Act and the SEC's rules, the Audit Committee may
delegate either type of pre-approval authority to one or more of its members.
The member to whom such authority is delegated must report, for informational
purposes only, any pre-approval decisions to the Audit Committee at its next
scheduled meeting.

3.    AUDIT SERVICES

      The annual Audit services engagement terms and fees are subject to the
specific pre-approval of the Audit Committee. Audit services include the annual
financial statement audit and other procedures required to be performed by the
Independent Auditors to be able to form an opinion on the Fund's financial
statements. These other procedures include information systems and procedural
reviews and testing performed in order to understand and place reliance on the
systems of internal control, and consultations relating to the audit. The Audit
Committee will monitor the Audit services engagement as necessary, but no less
than on a quarterly basis, and will also approve, if necessary, any changes in
terms, conditions and fees resulting from changes in audit scope, Fund structure
or other items.

      In addition to the annual Audit services engagement approved by the Audit
Committee, the Audit Committee may grant general pre-approval to other Audit
services, which are those services that only the Independent Auditors reasonably
can provide. Other Audit services may include statutory audits and services
associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4,
etc.), periodic reports and other documents filed with the SEC or other
documents issued in connection with securities offerings.

      The Audit Committee has pre-approved the Audit services in Appendix B.1.
All other Audit services not listed in Appendix B.1 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated).

4.    AUDIT-RELATED SERVICES

      Audit-related services are assurance and related services that are
reasonably related to the performance of the audit or review of the Fund's
financial statements or, to the extent they are Covered Services, the Covered
Entities' financial statements, or that are traditionally performed by the
Independent Auditors. Because the Audit Committee believes that the provision of
Audit-related services does not impair the independence of the auditor and is
consistent with the SEC's rules on auditor independence, the Audit Committee may
grant general pre-approval to Audit-related services. Audit-related services
include, among others, accounting consultations related to accounting, financial
reporting or disclosure matters not classified as "Audit services"; assistance
with understanding and implementing new accounting and financial reporting
guidance from rulemaking authorities; agreed-upon or expanded audit procedures
related to accounting and/or billing records required to respond to or comply
with financial, accounting or regulatory reporting matters; and assistance with
internal control reporting requirements under Forms N-SAR and/or N-CSR.



      The Audit Committee has pre-approved the Audit-related services in
Appendix B.2. All other Audit-related services not listed in Appendix B.2 must
be specifically pre-approved by the Audit Committee (or by any member of the
Audit Committee to which pre-approval has been delegated).

5.    TAX SERVICES

      The Audit Committee believes that the Independent Auditors can provide Tax
services to the Fund and, to the extent they are Covered Services, the Covered
Entities, such as tax compliance, tax planning and tax advice without impairing
the auditor's independence, and the SEC has stated that the Independent Auditors
may provide such services. Hence, the Audit Committee believes it may grant
general pre-approval to those Tax services that have historically been provided
by the Independent Auditors, that the Audit Committee has reviewed and believes
would not impair the independence of the Independent Auditors, and that are
consistent with the SEC's rules on auditor independence. The Audit Committee
will not permit the retention of the Independent Auditors in connection with a
transaction initially recommended by the Independent Auditors, the sole business
purpose of which may be tax avoidance and the tax treatment of which may not be
supported in the Internal Revenue Code and related regulations. The Audit
Committee will consult with Director of Tax or outside counsel to determine that
the tax planning and reporting positions are consistent with this policy.

      Pursuant to the preceding paragraph, the Audit Committee has pre-approved
the Tax Services in Appendix B.3. All Tax services involving large and complex
transactions not listed in Appendix B.3 must be specifically pre-approved by the
Audit Committee (or by any member of the Audit Committee to which pre-approval
has been delegated), including tax services proposed to be provided by the
Independent Auditors to any executive officer or trustee/director/managing
general partner of the Fund, in his or her individual capacity, where such
services are paid for by the Fund (generally applicable only to internally
managed investment companies).

6.    ALL OTHER SERVICES

      The Audit Committee believes, based on the SEC's rules prohibiting the
Independent Auditors from providing specific non-audit services, that other
types of non-audit services are permitted. Accordingly, the Audit Committee
believes it may grant general pre-approval to those permissible non-audit
services classified as All Other services that it believes are routine and
recurring services, would not impair the independence of the auditor and are
consistent with the SEC's rules on auditor independence.

      The Audit Committee has pre-approved the All Other services in Appendix
B.4. Permissible All Other services not listed in Appendix B.4 must be
specifically pre-approved by the Audit Committee (or by any member of the Audit
Committee to which pre-approval has been delegated).

      A list of the SEC's prohibited non-audit services is attached to this
policy as Appendix B.5. The SEC's rules and relevant guidance should be
consulted to determine the precise definitions of these services and the
applicability of exceptions to certain of the prohibitions.

7.    PRE-APPROVAL FEE LEVELS OR BUDGETED AMOUNTS

      Pre-approval fee levels or budgeted amounts for all services to be
provided by the Independent Auditors will be established annually by the Audit
Committee. Any proposed services exceeding these levels or amounts will require
specific pre-approval by the Audit Committee. The Audit Committee is mindful of
the overall relationship of fees for audit and non-audit services in determining
whether to pre-approve any such services. For each fiscal year, the Audit
Committee may determine the appropriate ratio between the total amount of fees
for Audit, Audit-related, and Tax services for the Fund (including any
Audit-related or Tax services fees for Covered Entities subject to
pre-approval), and the total amount of fees for certain permissible non-audit
services classified as All Other services for the Fund (including any such
services for Covered Entities subject to pre-approval).



8.    PROCEDURES

      All requests or applications for services to be provided by the
Independent Auditors that do not require specific approval by the Audit
Committee will be submitted to the Fund's Chief Financial Officer and must
include a detailed description of the services to be rendered. The Fund's Chief
Financial Officer will determine whether such services are included within the
list of services that have received the general pre-approval of the Audit
Committee. The Audit Committee will be informed on a timely basis of any such
services rendered by the Independent Auditors. Requests or applications to
provide services that require specific approval by the Audit Committee will be
submitted to the Audit Committee by both the Independent Auditors and the Fund's
Chief Financial Officer, and must include a joint statement as to whether, in
their view, the request or application is consistent with the SEC's rules on
auditor independence.

      The Audit Committee has designated the Fund's Chief Financial Officer to
monitor the performance of all services provided by the Independent Auditors and
to determine whether such services are in compliance with this Policy. The
Fund's Chief Financial Officer will report to the Audit Committee on a periodic
basis on the results of its monitoring. A sample report is included as Appendix
B.7. Both the Fund's Chief Financial Officer and management will immediately
report to the chairman of the Audit Committee any breach of this Policy that
comes to the attention of the Fund's Chief Financial Officer or any member of
management.

9.    ADDITIONAL REQUIREMENTS

      The Audit Committee has determined to take additional measures on an
annual basis to meet its responsibility to oversee the work of the Independent
Auditors and to assure the auditor's independence from the Fund, such as
reviewing a formal written statement from the Independent Auditors delineating
all relationships between the Independent Auditors and the Fund, consistent with
Independence Standards Board No. 1, and discussing with the Independent Auditors
its methods and procedures for ensuring independence.

10.   COVERED ENTITIES

      Covered Entities include the Fund's investment adviser(s) and any entity
controlling, controlled by or under common control with the Fund's investment
adviser(s) that provides ongoing services to the Fund(s). Beginning with
non-audit service contracts entered into on or after May 6, 2003, the Fund's
audit committee must pre-approve non-audit services provided not only to the
Fund but also to the Covered Entities if the engagements relate directly to the
operations and financial reporting of the Fund. This list of Covered Entities

of the Registrant. 100% of such services were pre-approved by the audit

(b) There were no changes in the registrant's internal control over financial
reporting that occurred during the registrant's most recent fiscal half-year

has materially affected, or is reasonably likely to materially affect, the
registrant's internal control over financial reporting.
