FUND REPORT

For the year ended October 31, 2005

MARKET CONDITIONS

Throughout the 12-month period ended October 31, 2005, economic reports
continued to show moderate growth, sustained consumer spending, and reasonable
gains in employment. Although core inflation (which excludes food and energy)
remained benign, inflationary concerns mounted during the summer as heavy demand
and geopolitical events drove oil prices to protracted highs. September brought
heightened uncertainty in the wake of the unprecedented devastation caused by
Hurricanes Rita and Katrina. The immediate economic impact was a major
disruption of the nation's energy infrastructure. However, in the weeks that
followed, economists generally agreed that an initial slowdown would be followed
by stimulus to growth from reconstruction.

The Federal Open Market Committee (the Fed) continued the "measured" rate
tightening cycle it began in June of 2004, raising the federal funds target rate
eight times during the 12-month period. As a result, the rate moved from 1.75
percent to 3.75 percent, a four-year high. Yet, as the period closed, signals
from the Fed supported investors' expectations of additional increases.

Although yields on short maturity bonds rose in response to the Fed's actions,
the yields of long-term municipal bonds were lower to unchanged. Representative
yields on 30-year AAA rated municipal bonds declined from 4.60 percent at the
start of the period to a low of 4.25 percent in the summer, returning to 4.60
percent at the end of October. Overall, the municipal yield curve continued to
flatten and the yield spread (or differential between one-year rates and 30-year
rates) narrowed. In this environment, the benefits of leveraged investment
strategies proved less advantageous. (Leverage involves borrowing at short-term
rates to purchase longer-term securities, thereby taking advantage of the
differential between short- and long-term yields.)

Lower yields during most of the year led to a surge in refinancing activity, and
municipal issuance remained strong. New issue volume increased by 12 percent to
a record $336 billion during the first 10 months of the calendar year. As
issuers rushed to refinance higher cost debt, refundings increased to 35 percent
of total issuance, up from 24 percent in the first 10 months of 2004. Bonds
backed by insurance dominated issuance and increased their market penetration to
nearly 60 percent. Issuers in California, New York, Texas, Florida and
Pennsylvania accounted for more than 40 percent of the total underwriting volume
during the year-to-date period.

The municipal-to-Treasury yield ratio, which gauges performance between the two
markets, remained attractive for tax-exempt bonds. The 30-year ratio averaged 97
percent during the period and moved as high as 102 percent in June. (Higher
ratios indicate increased relative attractiveness of municipal bonds.) As a
result, institutional investors that normally focus on taxable bond sectors
supported municipals by "crossing over" to purchase tax-exempt bonds.

PERFORMANCE ANALYSIS

For the 12-month period ended October 31, 2005, the net asset value (NAV) of
Morgan Stanley Insured Municipal Trust (IMT) decreased from $15.49 to $15.23 per
share. IMT paid tax-free dividends totaling $0.81 per share. The Trust's total
NAV return was 4.22 percent. IMT's value on the New York Stock Exchange (NYSE)
moved from $13.88 to $13.60 per share during the same period. Based on this
change plus reinvestment of dividends, the Trust's total market return was 3.86
percent. On October 31, 2005, IMT's NYSE market price was at a 10.70 percent
discount to its NAV. During the 12-month period ended October 31, 2005, the
Trust purchased and retired 840,542 shares of common stock at a weighted average
market discount of 10.73 percent. Past performance is no guarantee of future
results.

Monthly dividends for the fourth quarter of 2005, declared in September, were
unchanged at $0.0675 per share. The dividend reflects the current level of the
Trust's net investment income. IMT's level of undistributed net investment
income was $0.1149 per share on October 31, 2005, versus $0.090 per share 12
months earlier.(1)

During the period, the Trust maintained a conservative strategy in anticipation
of continued Fed tightening and higher interest rates. The Trust's duration* (a
measure of interest rate sensitivity) was positioned defensively throughout the
period. Overall, this duration stance tempered total returns early in the fiscal
period when rates declined, but helped total returns as rates rose. Reflecting
leverage, the Trust's option-adjusted duration was 9.7 years at the end of the
reporting period. Consistent with a commitment to diversification, the Trust's
net assets of $282 million were invested among 13 long-term sectors and 78
credits.

As discussed in previous reports, the total income available for distribution to
holders of common shares includes incremental income provided by the Trust's
outstanding Auction Rate Preferred Shares (ARPS). ARPS dividends reflect
prevailing short-term interest rates on maturities ranging from one week to two
years. Incremental income to holders of common shares depends on two factors:
the amount of ARPS outstanding and the spread between the portfolio's cost yield
and its ARPS auction rate and expenses. The greater the spread and the higher
the amount of ARPS outstanding, the greater the amount of incremental income
available for distribution to holders of common shares. The level of net
investment income available for distribution to holders of common shares varies
with the level of short-term interest rates. ARPS leverage also increases the
price volatility of common shares and has the effect of extending portfolio
duration.

During this 12-month period, ARPS leverage contributed approximately $0.19 per
share to common-share earnings. The Trust has 2 ARPS series totaling $130
million, representing 46 percent of net assets.

The Trust's procedure for reinvesting all dividends and distributions in common
shares is through purchases in the open market. This method helps support the
market value of the Trust's shares. In addition, we would like to remind you
that the Trustees have approved a procedure whereby the Trust may, when
appropriate, purchase shares in the open market or in privately negotiated
transactions at a price not above market value or net asset value, whichever is
lower at the time of purchase. The Trust may also utilize procedures to reduce
or eliminate the amount of ARPS outstanding, including their purchase in the
open market or in privately negotiated transactions.

PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF
FUTURE RESULTS, AND CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN THE FIGURES
SHOWN. INVESTMENT RETURN, NET ASSET VALUE AND COMMON SHARE MARKET PRICE WILL
FLUCTUATE AND TRUST SHARES, WHEN SOLD, MAY BE WORTH MORE OR LESS THAN THEIR
ORIGINAL COST.

* A measure of the sensitivity of a bond's price to changes in interest rates,
expressed in years. Each year of duration represents an expected 1 percent
change in the price of a bond for every 1 percent change in interest rates. The
longer a bond's duration, the greater the effect of interest-rate movements on
its price. Typically, trusts with shorter durations perform better in
rising-interest-rate environments, while trusts with longer durations perform
better when rates decline.

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

Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2005

1. Organization and Accounting Policies

Morgan Stanley Insured Municipal Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended, as a diversified, closed-end
management investment company. The Trust's investment objective is to provide
current income which is exempt from federal income tax. The Trust was organized
as a Massachusetts business trust on October 3, 1991 and commenced operations on
February 28, 1992.

The following is a summary of significant accounting policies:

A. Valuation of Investments -- (1) portfolio securities are valued by an outside
independent pricing service approved by the Trustees. The pricing service uses
both a computerized grid matrix of tax-exempt securities and evaluations by its
staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the mean between the last reported bid and
asked price. The portfolio securities are thus valued by reference to a
combination of transactions and quotations for the same or other securities
believed to be comparable in quality, coupon, maturity, type of issue, call
provisions, trading characteristics and other features deemed to be relevant.
The Trustees believe that timely and reliable market quotations are generally
not readily available for purposes of valuing tax-exempt securities and that the
valuations supplied by the pricing service are more likely to approximate the
fair value of such securities; (2) futures are valued at the latest sale price
on the commodities exchange on which they trade unless it is determined that
such price does not reflect their market value, in which case they will be
valued at their fair value as determined in good faith under procedures
established by and under the supervision of the Trustees; and (3) short-term
debt securities having a maturity date of more than sixty days at time of
purchase are valued on a mark-to-market basis until sixty days prior to maturity
and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.

B. Accounting for Investments -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted and premiums are amortized over the life of the
respective securities. Interest income is accrued daily.

C. Futures Contracts -- A futures contract is an agreement between two parties
to buy and sell financial instruments or contracts based on financial indices at
a set price on a future date. Upon entering into such a contract, the Trust is
required to pledge to the broker cash, U.S. Government securities or other
liquid portfolio securities equal to the minimum initial margin requirements of
the applicable futures exchange. Pursuant to the contract, the Trust agrees to
receive from or pay to the

Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2005 continued

broker an amount of cash equal to the daily fluctuation in the value of the
contract. Such receipts or payments known as variation margin are recorded by
the Trust as unrealized gains and losses. Upon closing of the contract, the
Trust realizes a gain or loss equal to the difference between the value of the
contract at the time it was opened and the value at the time it was closed.

D. Federal Income Tax Policy -- 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 and nontaxable
income to its shareholders. Accordingly, no federal income tax provision is
required.

E. Dividends and Distributions to Shareholders -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.

F. Use of Estimates -- The preparation of financial statements in accordance
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts and disclosures.
Actual results could differ from those estimates.

2. Investment Advisory/Administration Agreements

Pursuant to an Investment Management Agreement with Morgan Stanley Investment
Advisors Inc. (the "Investment Adviser"), the Trust pays an advisory fee,
calculated weekly and payable monthly, by applying the annual rate of 0.27% to
the Trust's weekly total net assets including preferred shares.

Pursuant to an Administration Agreement with Morgan Stanley Services Company
Inc. (the "Administrator"), an affiliate of the Investment Adviser, the Trust
pays an administration fee, calculated weekly and payable monthly, by applying
the annual rate of 0.08% to the Trust's weekly total net assets including
preferred shares.

3. Security Transactions and Transactions With Affiliates

The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended October 31, 2005 aggregated
$59,416,483 and $67,556,717, respectively.

Morgan Stanley Trust, an affiliate of the Investment Adviser and Administrator,
is the Trust's transfer agent.

The Trust has an unfunded noncontributory defined benefit pension plan covering
certain independent Trustees of the Trust who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on factors which include years of service and compensation. The
Trustees voted to close the plan to new participants and eliminate the future

Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2005 continued

benefits growth due to increases to compensation after July 31, 2003. Aggregate
pension costs for the year ended October 31, 2005 included in Trustees' fees and
expenses in the Statement of Operations amounted to $6,676. At October 31, 2005,
the Trust had an accrued pension liability of $56,691 which is included in
accrued expenses in the Statement of Assets and Liabilities.

The Trust has an unfunded Deferred Compensation Plan (the "Compensation Plan")
which allows each independent Trustee to defer payment of all, or a portion, of
the fees he receives for serving on the Board of Trustees. Each eligible Trustee
generally may elect to have the deferred amounts credited with a return equal to
the total return on one or more of the Morgan Stanley funds that are offered as
investment options under the Compensation Plan. Appreciation/depreciation and
distributions received from these investments are recorded with an offsetting
increase/decrease in the deferred compensation obligation and do not affect the
net asset value of the Trust.

4. Preferred Shares of Beneficial Interest

The Trust is authorized to issue up to 1,000,000 non-participating preferred
shares of beneficial interest having a par value of $.01 per share, in one or
more series, with rights as determined by the Trustees, without approval of the
common shareholders. The Trust has issued Series TU and TH Auction Rate
Preferred Shares ("preferred shares") which have a liquidation value of $50,000
per share plus the redemption premium, if any, plus accumulated but unpaid
dividends, whether or not declared, thereon to the date of distribution. The
Trust may redeem such shares, in whole or in part, at the original purchase
price of $50,000 per share plus accumulated but unpaid dividends, whether or not
declared, thereon to the date of redemption.

Dividends, which are cumulative, are reset through auction procedures.

AMOUNT RESET DIVIDEND
SERIES SHARES* IN THOUSANDS* RATE* DATE RATES**
------ ------- ------------- ----- -------- --------------

TU 800 $40,000 1.54% 01/04/06 1.54%
TH 1,800 90,000 2.65 11/03/05 1.449- 2.9

---------------------
* As of October 31, 2005.
** For the year ended October 31, 2005.

Subsequent to October 31, 2005 and up through December 2, 2005 the Trust paid
dividends to Series TU and TH at rates ranging from 1.54% to 3% in the aggregate
amount of $338,526.

The Trust is subject to certain restrictions relating to the preferred shares.
Failure to comply with these restrictions could preclude the Trust from
declaring any distributions to common shareholders or purchasing common shares
and/or could trigger the mandatory redemption of preferred shares at liquidation
value.

Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2005 continued

The preferred shares, which are entitled to one vote per share, generally vote
with the common shares but vote separately as a class to elect two Trustees and
on any matters affecting the rights of the preferred shares.

5. Common Shares of Beneficial Interest

Transactions in common shares of beneficial interest were as follows:

CAPITAL

EXCESS OF

6. Dividends to Common Shareholders

On September 27, 2005, the Trust declared the following dividends from net
investment income:

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

$0.0675 November 4, 2005 November 18, 2005
$0.0675 December 9, 2005 December 23, 2005

7. Expense Offset

The expense offset represents a reduction of the custodian fees for earnings on
cash balances maintained by the Trust.

8. Risks Relating to Certain Financial Instruments

The Trust may invest a portion of its assets in residual interest bonds, which
are inverse floating rate municipal obligations. The prices of these securities
are subject to greater market fluctuations during periods of changing prevailing
interest rates than are comparable fixed rate obligations.

To hedge against adverse interest rate changes, the Trust may invest in
financial futures contracts or municipal bond index futures contracts ("futures
contracts").

Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2005 continued

These futures contracts involve elements of market risk in excess of the amount
reflected in the Statement of Assets and Liabilities. The Trust bears the risk
of an unfavorable change in the value of the underlying securities. Risks may
also arise upon entering into these contracts from the potential inability of
the counterparties to meet the terms of their contracts.

9. Federal Income Tax Status

The amount of dividends and distributions from net investment income and net
realized capital gains are determined in accordance with federal income tax
regulations which may differ from generally accepted accounting principles.
These "book/tax" differences are either considered temporary or permanent in
nature. To the extent these differences are permanent in nature, such amounts
are reclassified within the capital accounts based on their federal tax-basis
treatment; temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for tax purposes are reported as distributions of paid-in-capital.

The tax character of distributions paid was as follows:

During the year ended October 31, 2005, the Trust utilized its net capital loss
carryforward of $3,341,240.

As of October 31, 2005, the Trust had temporary book/tax differences primarily
attributable to book amortization of discounts on debt securities,
mark-to-market of open futures contracts and dividend payable and permanent
book/tax differences attributable to tax adjustments on debt securities sold by
the Trust. To reflect reclassifications arising from the permanent differences,
accumulated undistributed net investment income was charged and accumulated
undistributed net realized gain was credited $226.

Morgan Stanley Insured Municipal Trust
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of
Morgan Stanley Insured Municipal Trust:

We have audited the accompanying statement of assets and liabilities of Morgan
Stanley Insured Municipal Trust (the "Trust"), including the portfolio of
investments, as of October 31, 2005, and the related statements of operations
for the year then ended and 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.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Trust
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Trust'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 October 31, 2005, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. 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 Morgan
Stanley Insured Municipal Trust as of October 31, 2005, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

APPENDIX A

AUDIT COMMITTEE
AUDIT AND NON-AUDIT SERVICES
PRE-APPROVAL POLICY AND PROCEDURES
OF THE
MORGAN STANLEY RETAIL AND INSTITUTIONAL FUNDS

AS ADOPTED AND AMENDED JULY 23, 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.

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 or its delegate ("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.

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 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.

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

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
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 and, to the extent they are Covered Services, the Covered Entities 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.

Pursuant to the preceding paragraph, the Audit Committee has pre-approved the
Tax Services in Appendix B.3. All Tax services 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).

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).

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.

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. 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
would include:
