MARKET CONDITIONS

The U.S. equity markets returned mixed results for the 12 months ending November
30, 2004, facing uncertainty for much of the period but rallying in the final
four months. Early in the period, investors remained focused on high-beta
sectors (those with volatility greater than that of the Russell 1000 Index) as
the threat of interest-rate hikes stayed low, and information technology and
other economically sensitive sectors led the market. Investors began to shift
assets toward more-defensive stocks after Federal Reserve Board Chairman Alan
Greenspan indicated that interest rates would likely rise in the near future and
after more mixed economic data came out. In the second half of the period,
economic growth was generally stronger than expected. The measured pace at which
interest-rate hikes were implemented by the Federal Open Market Committee
beginning June 2004 prevented the shift from seriously affecting market
performance. The labor market saw some improvement during this time, though the
job recovery did not occur at the pace some had expected. Investor confidence
was affected by fears of terrorism during the period, but the completion of the
two major political conventions and the presidential election eventually
provided a bounce for the market. Although rising oil prices were a concern for
investors later in the period, the retreat from a high in oil prices at the end
of October further helped an equities rally at the end of the period.

While all sectors had positive returns for the 12 months under review, some
outperformed others. Energy was the strongest-performing sector, making
significant gains as a result of rising oil prices in the second half of the
period. Utilities also performed well, as these stocks were helped greatly by
rising rates and lower costs of capital resulting from improved balance sheets.
Technology stocks underperformed in comparison, hampered by weak IT spending for
the period.

PERFORMANCE ANALYSIS

Performance for the period was healthy. Classes A and D of the Fund outperformed
both the KLD Large Cap Social(SM) Index* (The KLD Index) and Lipper Large-Cap
Core Funds Index. While Class B of the Fund underperformed both benchmarks,
Class C only outperformed the Lipper Large-Cap Core Funds Index. A number of
holdings across various sectors contributed to the Fund's positive performance
for the period, as gains were not limited to any particular part of the

                                        2
<Page>

market. Although the energy, utilities and basic materials sectors were the top
performers for the period, significant contributions were made by holdings in
financial services, technology and telecommunications as well. Among them,
Microsoft and Johnson & Johnson both made gains in April after their earnings
improved, surpassing expectations. AT&T Wireless was helped by the market's
positive reaction to its deal with Cingular. Some of the period's strongest
performers included Apple, Autodesk, Sirius Satellite, Valero Energy and eBay,
which all benefited the Fund to varying degrees. Apple benefited particularly
from impressive sales of its iPods over the period, while Valero was able to
capitalize on its refining margins. EBay was helped by a pickup in online sales
transactions, and Sirius made gains after signing radio talent Howard Stern.

While positive performance was driven by holdings across many sectors, the
stocks that hampered the Fund's gains were also not limited to any one sector.
Intel was one of the largest detractors from performance, as it suffered from
earnings disappointments early in the year. The technology stocks Cisco, Applied
Materials and Veritas were all hurt by a drop in overall technology spending and
unexpectedly low earnings for the sector as a whole. Within health care, Merck
became a hindrance on performance after suffering from problems that led to the
recall of its drug Vioxx.

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 management 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 06/01/04 - 11/30/04.

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.

   *  EXPENSES ARE EQUAL TO THE FUND'S ANNUALIZED EXPENSE RATIO OF 0.25%, 1.00%,
      1.00% AND 0% RESPECTIVELY, MULTIPLIED BY THE AVERAGE ACCOUNT VALUE OVER
      THE PERIOD, MULTIPLIED BY 183/366 (TO REFLECT THE ONE-HALF YEAR PERIOD).
      IF THE FUND HAD BORNE ALL OF ITS EXPENSES, THE ANNUALIZED EXPENSE RATIOS
      WOULD HAVE BEEN 3.53%, 4.28%, 4.28% AND 3.28%, RESPECTIVELY.

MORGAN STANLEY KLD SOCIAL INDEX FUND
NOTES TO FINANCIAL STATEMENTS - NOVEMBER 30, 2004

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 non-diversified,
open-end management investment company. The Fund's investment objective is to
provide investment results that before expenses corresponds 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 one year, 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.

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 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

                                       23

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.

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
Effective November 1, 2004, 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.

Effective November 1, 2004, 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 has agreed to waive its fee and assume all operating
expenses (except for distribution 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 assume all operating expenses (except for
distribution fees) and to waive the compensation provided for in its Investment
Advisory Agreement to the extent that such expenses and compensation on an
annual basis exceed 0.40% of the daily net assets of the Fund. At November 30,
2004, included in the Statement of Assets and Liabilities is a receivable from
affiliate, which represents expense reimbursements due to the Fund.

Prior to November 1, 2004, the Fund had retained the Investment Adviser to
provide administrative services and to manage the investment of the Fund's
assets pursuant to an investment management agreement pursuant to which the Fund
paid the Investment Adviser a monthly management fee accrued daily and payable
monthly, by applying the annual rate of 0.20% to the average net assets of the
Fund determined as of the close of each business day. Prior to May 1, 2004, the
annual rate was 0.40%.

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.

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

                                       25
<Page>

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 $1,130,833 at November 30, 2004.

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, 2004, the distribution fee was accrued for Class
A shares and Class C shares at the annual rate of 0.23% and 0.93%, respectively.

The Distributor has informed the Fund that for the year ended November 30, 2004,
it received contingent deferred sales charges from certain redemptions of the
Fund's Class A shares, Class B shares and Class C shares of $6, $20,787 and
$415, respectively and received $14,997 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, 2004 aggregated
$4,713,946 and $1,587,600, respectively.

Morgan Stanley Trust, an affiliate of the Investment Adviser, Administrator and
Distributor, is the Fund's transfer agent. At November 30, 2004, the Fund had
transfer agent fees and expenses payable of approximately $2,500.

Effective April 1, 2004, the Fund began 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.

                                       27

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:

As of November 30, 2004, the tax-basis components of accumulated losses were as
follows:

</Table>

*During the year ended November 30, 2004, the Fund utilized $250,216 of its net
capital loss carryforward. As of November 30, 2004, the Fund had a net capital
loss carryforward of $2,871,195 of which $1,967,974 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, 2004, 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 $3,026.

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 number of similar class action complaints which were recently

                                       28
<Page>

consolidated. This consolidated action also names as defendants certain
individual Trustees and Directors of the Morgan Stanley funds. The consolidated
amended complaint 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. While the Fund believes that it has meritorious defenses,
the ultimate outcome of this matter is not presently determinable at this early
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, 2004, 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. 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 November 30, 2004, by correspondence with the custodian
and broker. 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 Morgan
Stanley KLD Social Index Fund as of November 30, 2004, 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

                                     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.
