MARKET CONDITIONS

The annual reporting period opened on an optimistic note. Despite high oil
prices and ongoing increases to the federal funds target rate, stocks rallied
through December. The market was buoyed by a variety of factors, including the
undisputed presidential election, indications of steady economic growth, a pick
up in merger-and-acquisition activity and initial public offerings, as well as
good corporate earnings.

In contrast to the strong close of 2004, the first months of 2005 were far less
ebullient. Stocks retreated amid profit taking and deteriorating sentiment.
Investors grew increasingly apprehensive about soaring oil prices, inflationary
pressures, the Federal Open Market Committee's (the "Fed") interest rate
tightenings, and the pace of economic growth. Additionally, the misfortunes of
the auto industry called into question the strength of the U.S. economy.
Although oil prices continued to increase, the climate brightened by late
spring. Encouraging economic data, increased consumer confidence, waning
inflationary fears and many solid corporate earnings announcements boosted the
stock market.

Against the backdrop of mixed economic data and additional increases in the
federal funds rate, the markets became increasingly choppy from August through
mid-October. The Gulf Coast hurricanes sent oil prices spiking and created
anxiety about the economy, particularly given the Fed's resolve to continue
raising rates.

In mid-October, the stock market regained its equilibrium. Declining oil prices,
better-than-expected economic data, the nomination of Ben Bernanke to head the
Federal Reserve, and strengthening consumer trends provided a boost to investor
sentiment in the final portion of October. Stocks continued to advance through
November, buoyed by indications that the Fed might soon slow the pace of rate
increases, a boost in consumer confidence, continued declines in oil prices,
strong retail trends (excluding the auto industry), and acceptable housing data.

PERFORMANCE ANALYSIS

Morgan Stanley KLD Social Index Fund underperformed the KLD Large Cap Social(SM)
Index* for the 12 months ended November 30, 2005, after the deduction of the
Fund's fees and expenses and assuming no deduction of applicable sales charges.
Class A, B and D shares outperformed and Class C shares narrowly underperformed
the Lipper Large-Cap Core Funds Index for the same time period, assuming no
deduction of sales charges.

                                        2
<Page>

The gains of the Fund and the Index were supported by positive performance
across all 10 sectors of the Index. In terms of absolute returns, the top
performing sectors were energy, healthcare and utilities. Rising commodity
prices and increased demand provided support for the energy and utilities
sector. Within healthcare, the equipment and services industry was particularly
strong, boosted by pricing power and new plan member enrollments within
healthcare services. Biotechnology and pharmaceutical stocks also contributed to
the sector's gains as favorable drug trial results were well received by the
market.

While all the sectors generated positive performance, two industry groups landed
in negative territory. The auto sector was plagued by a host of issues,
including missed earnings, credit downgrades and labor problems. In the media
industry, traditional companies came under increased pressure from Internet
competitors for advertising revenues; stock-specific setbacks also hindered the
group.

Given that the KLD Large Cap Social(SM) Index is market capitalization weighted
(and that the Fund seeks to replicate the performance attributes of the Index,
before Fund fees), the overall contribution of each sector was influenced by its
relative size within the Index and the Fund portfolio. In terms of overall
contributions to returns, the healthcare, financial and technology sectors added
most significantly to positive performance. As discussed previously, healthcare
services, biotechnology and pharmaceuticals were among the principal drivers.
Much of the contribution of the financials and technology sectors reflected
their sizable weightings within the Index. That said, diversified financial
services performed briskly, boosted by investment banking activity, such as
mergers and acquisitions. Technology included pockets of both strength and
weakness, due to company specific factors.

On an industry level, media stocks slowed the pace of the Index and the Fund
most significantly. On a sector basis, the telecommunications sector contributed
the least to overall performance. Here, performance was hindered as the market
gravitated away from companies pursuing acquisitions.

From a market capitalization perspective, small cap stocks contributed the most
to upside performance, while mega caps lagged.

THERE IS NO GUARANTEE THAT ANY SECTORS MENTIONED WILL CONTINUE TO PERFORM WELL
OR THAT SECURITIES IN SUCH SECTORS WILL BE HELD BY THE FUND IN THE FUTURE.

EXPENSE EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments and redemption fees;
and (2) ongoing costs, including advisory fees; distribution and service (12b-1)
fees; and other Fund expenses. This example is intended to help you understand
your ongoing costs (in dollars) of investing in the Fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 06/01/05 - 11/30/05.

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
expenses based on the Fund's actual expense ratio and an assumed rate of return
of 5% per year before expenses, which is not the Fund's actual return. The
hypothetical account values and expenses may not be used to estimate the actual
ending account balance or expenses you paid for the period. You may use this
information to compare the ongoing cost of investing in the Fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) and redemption fees. Therefore, the second line of the table is
useful in comparing ongoing costs, and will not help you determine the relative
total cost of owning different funds. In addition, if these transactional costs
were included, your costs would have been higher.

MORGAN STANLEY KLD SOCIAL INDEX FUND

NOTES TO FINANCIAL STATEMENTS - NOVEMBER 30, 2005

1. ORGANIZATION AND ACCOUNTING POLICIES
Morgan Stanley KLD Social Index Fund (the "Fund") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Fund's investment objective is to
provide investment results that before expenses correspond to the total return
of the KLD Large Cap Social(SM) Index ("KLD Index"). The Fund was organized as a
Massachusetts business trust on April 6, 2001 and commenced operations on July
13, 2001.

The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase and some
Class A shares, and most Class B shares and Class C shares are subject to a
contingent deferred sales charge imposed on shares redeemed within eighteen
months, six years and one year, respectively. Class D shares are not subject to
a sales charge. Additionally, Class A shares, Class B shares and Class C shares
incur distribution expenses.

Effective August 29, 2005, the Board of Trustees of the Fund approved the
implementation of a 2% redemption fee on Class A shares, Class B shares, Class C
shares, and Class D shares, which is paid directly to the Fund, for shares
redeemed within seven days of purchase. The redemption fee is designed to
protect the Fund and its remaining shareholders from the effects of short-term
trading.

The following is a summary of significant accounting policies:

A. VALUATION OF INVESTMENTS -- (1) an equity portfolio security listed or traded
on the New York Stock Exchange ("NYSE") or American Stock Exchange or other
exchange is valued at its latest sale price prior to the time when assets are
valued; if there were no sales that day, the security is valued at the mean
between the last reported bid and asked price; (2) an equity portfolio security
listed or traded on the Nasdaq is valued at the Nasdaq Official Closing Price;
if there were no sales that day, the security is valued at the mean between the
last reported bid and asked price; (3) all other portfolio securities for which
over-the-counter market quotations are readily available are valued at the mean
between the last reported bid and asked price. In cases where a security is
traded on more than one exchange, the security is valued on the exchange
designated as the primary market; (4) for equity securities traded on foreign
exchanges, the last reported sale price or the latest bid price may be used if
there were no sales on a particular day; (5) futures are valued at the latest
price published by the commodities exchange on which they trade; (6) when market
quotations are not readily available or Morgan Stanley Investment Advisors Inc.
(the "Investment Adviser"), determines that the latest sale price, the bid price
or the mean between the last reported bid and asked price do not reflect a
security's market value, portfolio securities are valued at their fair value as
determined in good faith under procedures established by and under the general
supervision of the Fund's Trustees. Occasionally, developments affecting the
closing prices of securities and other assets may occur between the times at
which valuations of such securities are determined (that is, close of the
foreign market on which the securities trade) and the

                                       23
<Page>

close of business on the NYSE. If developments occur during such periods that
are expected to materially affect the value of such securities, such valuations
may be adjusted to reflect the estimated fair value of such securities as of the
close of the NYSE, as determined in good faith by the Fund's Trustees or by the
Investment Adviser using a pricing service and/or procedures approved by the
Trustees of the Fund; and (7) 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.
Dividend income and other distributions are recorded on the ex-dividend date.
Discounts are accreted and premiums are amortized over the life of the
respective securities. Interest income is accrued daily.

C. REPURCHASE AGREEMENTS -- Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated
entities managed by the Investment Adviser, may transfer uninvested cash
balances into one or more joint repurchase agreement accounts. These balances
are invested in one or more repurchase agreements and are collateralized by
cash, U.S. Treasury or federal agency obligations. The Fund may also invest
directly with institutions in repurchase agreements. The Fund's custodian
receives the collateral, which is marked-to-market daily to determine that the
value of the collateral does not decrease below the repurchase price plus
accrued interest.

D. MULTIPLE CLASS ALLOCATIONS -- Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date such
items are recognized. Distribution fees are charged directly to the respective
class.

E. 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 Fund 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 Fund agrees to
receive from or pay to the 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 Fund as unrealized gains and losses. Upon
closing of the contract, the Fund 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.

                                       24

F. FEDERAL INCOME TAX POLICY -- It is the Fund'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. Accordingly, no federal income tax provision is required.

G. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.

H. 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 Advisory Agreement, the Fund pays the Investment
Adviser an advisory fee, accrued daily and payable monthly, by applying the
annual rate of 0.12% to the daily net assets of the Fund determined as of the
close of each business day.

Pursuant to an Administration Agreement with Morgan Stanley Services Company
Inc. (the "Administrator"), an affiliate of the Investment Adviser, the Fund
pays an administration fee, accrued daily and payable monthly, by applying the
annual rate of 0.08% to the Fund's daily net assets.

The Investment Adviser and Administrator have agreed to waive their fees and
assume all operating expenses (except for brokerage and 12b-1 fees) until such
time as the Fund has $50 million of net assets or April 30, 2006, whichever
occurs first. Thereafter, the Investment Adviser has agreed to cap the Fund's
operating expenses (except for brokerage and 12b-1 fees) by assuming the Fund's
"other expenses" and/or waiving the Fund's advisory fees, and the Administrator
has agreed to waive the Fund's administration fees, to the extent that such
operating expenses exceed 0.40% of the average daily net assets of the Fund on
an annualized basis.

At November 30, 2005, included in the Statement of Assets and Liabilities is a
receivable from affiliate, which represents expense reimbursements due to the
Fund.

3. PLAN OF DISTRIBUTION
Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the
"Distributor"), an affiliate of the Investment Adviser and Administrator. The
Fund has adopted a Plan of Distribution (the "Plan") pursuant to Rule 12b-1
under the Act. The Plan provides that the Fund will pay the Distributor a fee
which is accrued daily and paid monthly at the following annual rates: (i) Class
A -- up to 0.25% of the average daily net assets of Class A; (ii) Class B -- up
to 1.0% of the average daily net assets of Class B; and (iii) Class C -- up to
1.0% of the average daily net assets of Class C.

                                       25
<Page>

In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund pursuant
to the Plan and contingent deferred sales charges paid by investors upon
redemption of Class B shares. Although there is no legal obligation for the Fund
to pay expenses incurred in excess of payments made to the Distributor under the
Plan and the proceeds of contingent deferred sales charges paid by investors
upon redemption of shares, if for any reason the Plan is terminated, the
Trustees will consider at that time the manner in which to treat such expenses.
The Distributor has advised the Fund that such excess amounts totaled $1,057,057
at November 30, 2005.

In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 1.0% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales credit to Morgan Stanley Financial Advisors or other selected
broker-dealer representatives may be reimbursed in the subsequent calendar year.
For the year ended November 30, 2005, the distribution fee was accrued for Class
A shares and Class C shares at the annual rate of 0.22% and 1.0%, respectively.

The Distributor has informed the Fund that for the year ended November 30, 2005,
it received contingent deferred sales charges from certain redemptions of the
Fund's Class B shares and Class C shares of $23,772 and $27, respectively and
received $11,107 in front-end sales charges from sales of the Fund's Class A
shares. The respective shareholders pay such charges which are not an expense of
the Fund.

4. 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 November 30, 2005, aggregated
$269,575 and $385,067, respectively.

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

The Fund 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 Fund.

6. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS
The Fund may purchase and sell stock index futures ("futures contracts") for the
following reasons: to simulate full investment in the KLD Index while retaining
a cash balance for fund management purposes; to facilitate trading; to reduce
transaction costs; or to seek higher investment returns when a futures contract
is priced more attractively than stocks comprising the KLD Index.

These futures contracts involve elements of market risk in excess of the amount
reflected in the Statement of Assets and Liabilities. The Fund 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
counter parties to meet the terms of their contracts.

7. 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 November 30, 2005, the Fund utilized $162,763 of its net
capital loss carryforward. As of November 30, 2005, the Fund had a net capital
loss carryforward of $2,705,564 of which $1,802,343 will expire on November 30,
2010 and $903,221 will expire on November 30, 2011 to offset future capital
gains to the extent provided by regulations.

As of November 30, 2005, the Fund had temporary book/tax differences primarily
attributable to capital loss deferrals on wash sales and mark-to-market of open
futures contracts and permanent book/tax differences attributable to tax
adjustments on real estate investment trusts held by the Fund. To reflect
reclassifications arising from the permanent differences, accumulated
undistributed net investment income was charged and accumulated net realized
loss was credited $3,834.

8. LEGAL MATTERS
The Investment Adviser, certain affiliates of the Investment Adviser, certain
officers of such affiliates and certain investment companies advised by the
Investment Adviser or its affiliates, including the Fund, are named as
defendants in a consolidated class action. This consolidated action also names
as defendants

                                       28
<Page>

certain individual Trustees and Directors of the Morgan Stanley funds. The
consolidated amended complaint, filed in the United States District Court
Southern District of New York on April 16, 2004, generally alleges that
defendants, including the Fund, violated their statutory disclosure obligations
and fiduciary duties by failing properly to disclose (i) that the Investment
Adviser and certain affiliates of the Investment Adviser allegedly offered
economic incentives to brokers and others to recommend the funds advised by the
Investment Adviser or its affiliates to investors rather than funds managed by
other companies, and (ii) that the funds advised by the Investment Adviser or
its affiliates, including the Fund, allegedly paid excessive commissions to
brokers in return for their efforts to recommend these funds to investors. The
complaint seeks, among other things, unspecified compensatory damages,
rescissionary damages, fees and costs. The defendants have moved to dismiss the
action and intend to otherwise vigorously defend it. On March 9, 2005,
Plaintiffs sought leave to supplement their complaint to assert claims on behalf
of other investors. While the Fund and Adviser believe that each has meritorious
defenses, the ultimate outcome of this matter is not presently determinable at
this stage of the litigation, and no provision has been made in the Fund's
financial statements for the effect, if any, of this matter.

MORGAN STANLEY KLD SOCIAL INDEX FUND

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE SHAREHOLDERS AND BOARD OF
TRUSTEES OF MORGAN STANLEY KLD SOCIAL INDEX FUND:

We have audited the accompanying statement of assets and liabilities of Morgan
Stanley KLD Social Index Fund (the "Fund"), including the portfolio of
investments, as of November 30, 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 periods
presented. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Fund
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 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 November 30, 2005, by correspondence with the
custodian and broker. 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 KLD Social Index Fund as of November 30, 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 periods presented, in conformity with accounting principles generally
accepted in the United States of America.

                                 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.

<Page>

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

<Page>

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

<Page>

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
