MARKET CONDITIONS

The reporting period opened on a positive note following a string of strong
economic data. Investor sentiment reflected anticipation that the Federal Open
Market Committee (the Fed) would raise interest rates. This indeed proved to be
the case. Beginning in June, the Fed began a series of increases to the federal
funds rate, which brought the rate to 2.75 percent at the close of the reporting
period.

Continued softness in the economy pushed yields on intermediate and
longer-maturity securities lower in the third and into the fourth quarter of
2004. The market's concerns were fueled by continued weakness in employment
growth, anxiety about the U.S trade deficit and budget deficit, steady rises in
oil prices and uncertainty over the outcome of the U.S. presidential election.
The climate changed in November, however, when a surprisingly strong increase in
non-farm payrolls and in producer and consumer price indices pushed rates
higher. This improved sentiment continued well into the first quarter of 2005 as
rates continued to rise.

Against this backdrop, the yield curve flattened overall. Short- and
intermediate-term yields rose across the U.S. Treasury curve, while longer term
(10 years and longer) yields declined.

Performance among U.S. government and mortgage sectors varied during the period.
Treasuries and agencies posted the least impressive performance among the major
fixed-income sectors, due to their relative lack of yield and greater
sensitivity to changes in interest rates. Higher coupon mortgage-backed
securities, which tend to be less sensitive to rising interest rates,
outperformed their lower-coupon peers during the period.

Generally, corporate issues performed well due to investors' desire for
higher-yielding securities. Nevertheless, corporate yield spreads widened during
the first four months of 2005, most notably within the auto sector. General
Motors' (GM) lowered earnings guidance for the balance of 2005 took a toll on
its bonds, and also cast a shadow across the auto and auto-related industry.

PERFORMANCE ANALYSIS

Morgan Stanley Limited Duration Fund underperformed both the Lehman Brothers 1-5
Year U.S. Credit Index and the Lipper Short Investment Grade Debt Funds Index
for the 12 months ended April 30, 2005.

Within the government sector, performance was varied. The Fund's emphasis on
higher-coupon, slow-prepaying mortgage issues benefited the Fund as rates rose
during the bulk of the period. Because of this focus, the Fund was less
susceptible to market volatility. However, an underweight to the agency sector
detracted slightly from relative performance as spreads tightened. Additionally,
the Fund's U.S. Treasuries generated more muted performance due to their
relative lack of yield.

Within the corporate debt sector, the Fund gained from its emphasis on insurance
companies, which outperformed for the period. Strong security selection in the
energy sector further enhanced returns. Additionally, a benchmark-neutral
weighting in the auto sector benefited relative performance in 2005. On the
upside, the portfolio's exposure to medium-quality issues benefited relative
performance during the majority of the period.

Overall, paper, gaming and lodging, and energy credits remain the emphasis of
the portfolio's medium-quality corporate holdings. Within the high-quality
segment, our sole overweight relative to the benchmark is in the insurance area.

Throughout the reporting period, we managed the Fund's overall duration*, or
interest-rate sensitivity, to be in line with ("neutral") or below that of its
benchmark. The defensive, below-benchmark duration was beneficial as interest
rates rose across the short and intermediate-portions of the curve. The neutral
position benefited relative performance during periods when rates declined.

* 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, FUNDS WITH SHORTER DURATIONS PERFORM BETTER IN
RISING-INTEREST-RATE ENVIRONMENTS, WHILE FUNDS WITH LONGER DURATIONS PERFORM
BETTER WHEN RATES DECLINE.

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

EXPENSE EXAMPLE

As a shareholder of the Fund, you incur ongoing costs, including management
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 11/01/04 - 04/30/05.

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. 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 that have transactional costs, such as sales charges
(loads), and redemption fees, or exchange fees.

INVESTMENT ADVISORY AGREEMENT APPROVAL

NATURE, EXTENT AND QUALITY OF SERVICES

The Board reviewed and considered the nature and extent of the investment
advisory services provided by the Investment Adviser under the Advisory
Agreement, including portfolio management, investment research and fixed income
securities trading. The Board also reviewed and considered the nature and extent
of the non-advisory, administrative services provided by the Fund's
Administrator under the Administration Agreement, including accounting,
clerical, bookkeeping, compliance, business management and planning, and the
provision of supplies, office space and utilities at the Adviser's expense. (The
Investment Adviser and the Administrator together are referred to as the
"Adviser" and the Advisory and Administration Agreements together are referred
to as the "Management Agreement.") The Board also compared the nature of the
services provided by the Adviser with similar services provided by
non-affiliated advisers as reported to the Board by Lipper Inc. ("Lipper").

The Board reviewed and considered the qualifications of the portfolio managers,
the senior administrative managers and other key personnel of the Adviser who
provide the administrative and investment advisory services to the Fund. The
Board determined that the Adviser's portfolio managers and key personnel are
well qualified by education and/or training and experience to perform the
services in an efficient and professional manner. The Board concluded that the
nature and extent of the advisory and administrative services provided were
necessary and appropriate for the conduct of the business and investment
activities of the Fund. The Board also concluded that the overall quality of the
advisory and administrative services was satisfactory.

PERFORMANCE RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS

The Board reviewed the Fund's performance for one-, three- and five-year periods
ended November 30, 2004, as shown in reports provided by Lipper (the "Lipper
Reports"), compared to the performance of comparable funds selected by Lipper
(the "performance peer group"), and noted that the Fund's performance was lower
than its performance peer group average for all three periods. The Adviser
informed the Board that the Fund's relative performance was hindered during a
period of declining interest rates due to the defensive positioning of the
Fund's portfolio. The Board discussed with the Adviser possible steps to improve
performance. The Board concluded that the relative underperformance was
understandable in view of the defensive positioning and corresponding lower risk
of the Fund's investments.

FEES RELATIVE TO OTHER FUNDS MANAGED BY THE ADVISER WITH COMPARABLE INVESTMENT
STRATEGIES

The Board reviewed the advisory and administrative fees (together, the
"management fee") paid by the Fund under the Management Agreement. The Board
noted that the management fee rate was higher than the management fee rates
charged by the Adviser to any other funds it manages with investment strategies
comparable to those of the Fund. The Board also noted, as discussed below, that
the rate was competitive with contractual rates charged by other advisers for
comparable funds.

                                        9
<Page>

FEES AND EXPENSES RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS

The Board reviewed the management fee rate and total expense ratio of the Fund.
The Board noted that: (i) the Fund's management fee rate was higher than the
average management fee rate for funds, selected by Lipper (the "expense peer
group"), managed by other advisers with investment strategies comparable to
those of the Fund, as shown in the Lipper Report for the Fund; and (ii) the
Fund's total expense ratio was slightly higher than the average total expense
ratio of the mutual funds included in the Fund's expense peer group. The Board
also noted that most of the other funds in the expense peer group were waiving
part of their fees. The Board noted that the fee waivers by those funds were not
contractual obligations and could be terminated without shareholder consent and,
therefore, that the average fee excluding these waivers was a more valid
comparison. The Board concluded that the Fund's contractual management fee and
total expense ratio were competitive with those of the Fund's expense peer
group.

BREAKPOINTS AND ECONOMIES OF SCALE

The Board reviewed the structure of the Fund's management fee schedule under the
Management Agreement and noted that it includes breakpoints. The Board also
reviewed the level of the Fund's management fee and noted that the fee, as a
percentage of the Fund's net assets, would decrease as net assets increase
because the management fee includes breakpoints. The Board concluded that the
Fund's management fee would reflect economies of scale as assets increase.

PROFITABILITY OF ADVISER AND AFFILIATES

The Board considered and reviewed information concerning the costs incurred and
profits realized by the Adviser and its affiliates during the last two years
from their relationship with the Fund and the Morgan Stanley Fund Complex and
reviewed with the Controller of the Adviser the cost allocation methodology used
to determine the Adviser's profitability. Based on their review of the
information they received, the Board concluded that the profits earned by the
Adviser and its affiliates were not excessive in light of the advisory,
administrative and other services provided to the Fund.

FALL-OUT BENEFITS

The Board considered so-called "fall-out benefits" derived by the Adviser and
its affiliates from their relationship with the Fund and the Fund Complex, such
as "float" benefits derived from handling of checks for purchases and
redemptions of Fund shares through a broker-dealer affiliate of the Adviser. The
Board considered the float benefits and concluded that they were relatively
small.

SOFT DOLLAR BENEFITS

The Board considered whether the Adviser realizes any benefits from commissions
paid to brokers who execute securities transactions for the Fund ("soft
dollars"). The Board noted that the Fund invests only in fixed income
securities, which do not generate soft dollars.

ADVISER FINANCIALLY SOUND AND FINANCIALLY CAPABLE OF MEETING THE FUND'S NEEDS

The Board considered whether the Adviser is financially sound and has the
resources necessary to perform its obligations under the Management Agreement.
The Board noted that the Adviser's operations remain profitable, although
increased expenses in recent years have reduced the Adviser's profitability. The
Board concluded that the Adviser has the financial resources necessary to
fulfill its obligations under the Management Agreement.

HISTORICAL RELATIONSHIP BETWEEN THE FUND AND THE ADVISER

The Board also reviewed and considered the historical relationship between the
Fund and the Adviser, including the organizational structure of the Adviser, the
policies and procedures formulated and adopted by the Adviser for managing the
Fund's operations and the Board's confidence in the competence and integrity of
the senior managers and key personnel of the Adviser. The Board concluded that
it is beneficial for the Fund to continue its relationship with the Adviser.

OTHER FACTORS AND CURRENT TRENDS

The Board considered the controls and procedures adopted and implemented by the
Adviser and monitored by the Fund's Chief Compliance Officer and concluded that
the conduct of business by the Adviser indicates a good faith effort on its part
to adhere to high ethical standards in the conduct of the Fund's business.

GENERAL CONCLUSION

After considering and weighing all of the above factors, the Board concluded it
would be in the best interest of the Fund and its shareholders to approve
renewal of the Management Agreement for another year.

MORGAN STANLEY LIMITED DURATION FUND
NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2005

1. ORGANIZATION AND ACCOUNTING POLICIES
Morgan Stanley Limited Duration Fund (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The Fund's investment objective is to provide a
high level of current income consistent with the preservation of capital. The
Fund was organized as a Massachusetts business trust on October 22, 1993 and
commenced operations on January 10, 1994.

The following is a summary of significant accounting policies:

A. VALUATION OF INVESTMENTS -- (1) certain portfolio securities may be valued by
an outside pricing service approved by the Fund's Trustees (2) 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; (3)
futures are valued at the latest price published by the commodities exchange on
which they trade; (4) when market quotations are not readily available or Morgan
Stanley Investment Advisors Inc. (the "Investment Adviser") determines that the
market quotations are not reflective of 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; and (5) 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. 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. 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

                                       26
<Page>

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.

E. 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.

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

G. 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 with
the Investment Adviser, the Fund pays an advisory fee, accrued daily and payable
monthly, by applying the following annual rates to the net assets of the Fund
determined as of the close of each business day: 0.52% of the portion of the
daily net assets not exceeding $1 billion; 0.47% to the portion of daily net
assets exceeding $1 billion but not exceeding $2 billion and 0.42% of the
portion of daily net assets exceeding $2 billion.

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.

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 agreement pursuant to which the Fund paid the
Investment Adviser a monthly management fee accrued daily and payable monthly,
by applying the following annual rates to the net assets of the Fund determined
as of the close of each business day: 0.60% of the portion of the daily net
assets not exceeding $1 billion; 0.55% to the portion of daily net assets
exceeding $1 billion but not exceeding $2 billion and 0.50% of the portion of
daily net assets exceeding $2 billion.

                                       27

3. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
The cost of purchases and proceeds from sales/prepayments of portfolio
securities, excluding short-term investments, for the year ended April 30, 2005
were $353,175,544, and $521,245,740, respectively. Included in the
aforementioned are purchases and sales/prepayments of U.S. Government securities
of $273,470,195 and $423,312,043, respectively.

Morgan Stanley Trust, an affiliate of the Investment Adviser and Administrator,
is the Fund's transfer agent. At April 30, 2005, the Fund had transfer agent
fees and expenses payable of approximately $5,200.

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.

4. SHARES OF BENEFICIAL INTEREST

</Table>

5. 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

                                       28
<Page>

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:

                                           ==============
</Table>

*As of April 30, 2005, the Fund had a net capital loss carryforward of
$19,274,017 of which $1,656,930 will expire on April 30, 2006, $20,504 will
expire on April 30, 2007, $51,242 will expire on April 30, 2008, $2,035,052 will
expire on April 30, 2009, $1,582,163 will expire on April 30, 2011, $2,183,130
will expire on April 30, 2012 and $11,744,996 will expire on April 30, 2013 to
offset future capital gains to the extent provided by regulations.

As of April 30, 2005, the Fund had temporary book/tax differences primarily
attributable to post-October losses (capital losses incurred after October 31
within the taxable year which are deemed to arise on the first business day of
the Fund's next taxable year), and book amortization of premiums on debt
securities and permanent book/tax differences attributable to losses on
paydowns, tax adjustments on debt securities sold by the Fund and an expired
capital loss carryforward. To reflect reclassifications arising from the
permanent differences, paid-in-capital was charged $151,743, accumulated net
realized loss was charged $5,894,691 and dividends in excess of net investment
income was credited $6,046,434.

6. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS
To hedge against adverse interest rate and market risks on portfolio positions
or anticipated positions in U.S. Government securities, the Fund may enter into
interest rate futures contracts ("futures contracts").

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. Risk may also
arise upon entering into contracts from the potential inability of counterparts
to meet the terms of their contacts.

7. EXPENSE OFFSET
The expense offset represents a reduction of the custodian fees for earnings on
cash balances maintained by the Fund.

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 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. On March 10, 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 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 LIMITED DURATION FUND
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE SHAREHOLDERS AND BOARD OF
TRUSTEES OF MORGAN STANLEY LIMITED DURATION FUND:

We have audited the accompanying statement of assets and liabilities of Morgan
Stanley Limited Duration Fund (the "Fund"), including the portfolio of
investments, as of April 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 five years in
the period then ended. 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 April 30, 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 Limited Duration Fund as of April 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 five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

        (1)     The Fund's Code of Ethics is attached hereto as Exhibit A.

Item 3.  Audit Committee Financial Expert.

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

                                 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
