MARKET CONDITIONS

Economic reports continued to show moderate growth in 2005, sustained by
consumer spending and reasonable gains in employment. Core inflation (which
excludes food and energy) remained benign, but protracted high oil prices
fostered inflationary concerns, particularly during the summer. The
unprecedented devastation caused by Hurricanes Rita and Katrina in September
heightened the market's uncertainty. While the immediate economic impact was a
major disruption of the nation's energy infrastructure, the economy showed
considerable resilience in the fourth quarter. In fact, the consensus view
developed that accelerated reconstruction in storm-ravaged areas would serve as
a stimulus to future economic growth.

Throughout the year, the Federal Open Market Committee (the "Fed") continued the
rate tightening pattern that began in June of 2004 and raised the federal funds
target rate eight times in 25 basis point (0.25 percentage points) increments.
As a result, the rate increased from 2.25 percent to 4.25 percent.

Yields on short-term municipal bonds followed the target rate during 2005 and
rose steadily. In contrast, long-term bond yields were little changed for the
period overall, reflecting strong demand for longer maturity bonds and the
market's perception that the Fed was controlling inflation pressures. The slope
of the yield curve flattened as the difference between short-term and long-term
interest rates narrowed substantially. Representative yields on 30-year AAA
rated municipal bonds ranged from a low of 4.20 percent in June to a high of
4.65 percent in November. At the end of December, the yield stood at 4.40
percent. Investors' quest for yield favored lower-quality bonds over high-grade
issues and kept credit spreads relatively tight. (Credit spreads measure the
added compensation investors require to assume additional credit risk. When
credit spreads tighten, lower-rated issues typically outperform.)

Long-term municipal volume increased 13 percent to a record $408 billion in
2005. The flatter yield curve and low long-term interest rates encouraged
municipalities to refinance their debt. Such refundings accounted for 30 percent
of annual volume, nearly a 50 percent increase over 2004. New York remained a
leading issuer of municipal debt and accounted for 11 percent of total volume in
2005.

The municipal-to-Treasury yield ratio, which gauges the performance between the
two markets, remained attractive for tax-exempt bonds. During the year, the
ratio

                                        2
<Page>

of 10-year municipals to 10-year Treasuries averaged 86 percent and the 30-year
ratio averaged 97 percent. (The higher the ratio, the greater the attractiveness
of municipal yields relative to Treasury yields.) As a result, institutional
investors -- such as hedge funds and arbitrage accounts -- that normally focus
on taxable bond sectors "crossed-over" to purchase municipal bonds. Demand from
individual investors was less robust, given the low absolute level of yields.

The State of New York benefited from fiscal, economic and credit improvements
throughout the year. Moderate growth has kept New York's economy on a steady
course. In the New York City area, commercial real-estate markets showed
continued strength. The securities industry reported strong business activity,
as well as increased hiring and compensation. Among other positives, the State's
budget surplus grew and unemployment rates remained in a downward trend. The
State also received a credit rating upgrade.

PERFORMANCE ANALYSIS

Morgan Stanley New York Tax-Free Income Fund underperformed the Lehman Brothers
New York Exempt Index, the Lehman Brothers Municipal Bond Index and the Lipper
New York Municipal Debt Funds Index for the 12 months ended December 31, 2005,
assuming no deduction of applicable sales charges.

In anticipation of Fed tightenings and generally higher interest rates, the Fund
made modest ongoing adjustments to its long-term portfolio to reduce volatility.
For example, the Fund's interest-rate sensitivity was positioned conservatively.
At the close of the period, the Fund's option-adjusted duration* was 6.0 years.
The Fund used proceeds from the sale of refunded issues to purchase premium
coupon bonds with defensive characteristics.

Overall, the Fund maintained a high average credit quality with nearly 85
percent of the bonds in its portfolio rated A or higher as of the close of the
reporting period. The Fund benefited from its exposure to single A and BBB rated
credits in the hospital and industrial development/pollution control sectors.
These bonds performed well as investors sought higher-yielding bonds and credit
spreads tightened. Reflecting a commitment to diversification, the Fund's net
assets of approximately $104 million were invested among 11 long-term sectors
and 40 credits.

* 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 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 07/01/05 - 12/31/05.

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.

*    EXPENSES ARE EQUAL TO THE FUND'S ANNUALIZED EXPENSE RATIO OF 0.90%, 0.73%,
     1.40% AND 0.65% FOR CLASS A, CLASS B, CLASS C AND CLASS D SHARES,
     RESPECTIVELY, MULTIPLIED BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD,
     MULTIPLIED BY 184/365 (TO REFLECT THE ONE-HALF YEAR PERIOD). IF THE FUND
     HAD BORNE ALL OF ITS EXPENSES, THE ANNUALIZED EXPENSE RATIOS WOULD HAVE
     BEEN 1.03%, 0.86%, 1.53% AND 0.78% FOR CLASS A, CLASS B, CLASS C AND CLASS
     D SHARES, RESPECTIVELY.

     BECAUSE CLASS B SHARES INCURRED LOWER EXPENSES UNDER THE 12b-1 PLAN THAN
     CLASS A SHARES FOR THE SIX MONTHS ENDED DECEMBER 31, 2005, THE TOTAL
     OPERATING EXPENSE RATIO FOR CLASS B SHARES WAS LOWER AND, AS A RESULT, THE
     PERFORMANCE OF CLASS B SHARES WAS HIGHER THAN THAT OF THE CLASS A SHARES.
     THERE CAN BE NO ASSURANCE THAT THIS WILL CONTINUE TO OCCUR IN THE FUTURE AS
     THE MAXIMUM FEES PAYABLE BY CLASS B SHARES UNDER THE 12b-1 PLAN ARE HIGHER
     THAN THOSE PAYABLE BY CLASS A SHARES.

MORGAN STANLEY NEW YORK TAX-FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 2005

1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley New York Tax-Free Income 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 a high level of current income which is exempt from federal, New York
State and New York City income tax, consistent with the preservation of capital.
The Fund was organized as a Massachusetts business trust on January 17, 1985 and
commenced operations on April 25, 1985. On July 28, 1997, the Fund converted to
a multiple class share structure.

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

                                       18
<Page>

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. 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.

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 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 and nontaxable
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

Pursuant to an Investment Advisory Agreement with Morgan Stanley Investment
Advisers, Inc. (the "Investment Adviser"), the Fund pays the Investment Adviser
an advisory fee, accrued daily and payable monthly, by applying the following
annual rates to the Fund's net assets determined as of the close of each
business day: 0.47% to the portion of the daily net assets not exceeding $500
million and 0.445% to the portion of the daily net assets exceeding $500
million.

                                       19
<Page>

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 cap the Fund's operating expenses (except
for 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
administrative fees, to the extent that such operating expenses exceed 0.65% of
the average daily net assets of the Fund on an annualized basis.

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 0.75% of the lesser of: (a) the average daily aggregate gross sales of the
Class B shares since the inception of the Fund (not including reinvestment of
dividend or capital gain distributions) less the average daily aggregate net
asset value of the Class B shares redeemed since the Fund's inception upon which
a contingent deferred sales charge has been imposed or waived; or (b) the
average daily net assets of Class B; and (iii) Class C -- up to 0.75% 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 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 there were no excess expenses as of
December 31, 2005.

For the year ended December 31, 2005, the distribution fee for Class B shares
was accrued at the annual rate of 0.55%. At December 31, 2005, included in the
Statement of Assets and Liabilities, is a receivable from affiliate, which
represents payments due from the Distributor to the Fund.

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 0.75% 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

                                       20
<Page>

broker-dealer representatives may be reimbursed in the subsequent calendar year.
For the year ended December 31, 2005, the distribution fee was accrued for Class
A shares and Class C shares at the annual rate of 0.24% and 0.75%, respectively.

The Distributor has informed the Fund that for the year ended December 31, 2005,
it received contingent deferred sales charges from certain redemptions of the
Fund's Class B shares and Class C shares of $67,144 and $251, respectively and
received $21,909 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 December 31, 2005 aggregated
$15,759,940 and $30,376,562, respectively.

Morgan Stanley Trust, an affiliate of the Investment Adviser, Administrator and
Distributor, is the Fund's transfer agent. Included in the aforementioned
transactions are purchases of $1,040,192 with other Morgan Stanley Funds.

The Fund has an unfunded noncontributory defined benefit pension plan covering
certain independent Trustees of the Fund who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on factors which include years of service and compensation. The
Trustees voted to close the plan to new participants and eliminate the future
benefits growth due to increases to compensation after July 31, 2003. Aggregate
pension costs for the year ended December 31, 2005 included in Trustees' fees
and expenses in the Statement of Operations amounted to $7,377. At December 31,
2005, the Fund had an accrued pension liability of $63,321 which is included in
accrued expenses in the Statement of Assets and Liabilities.

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.

5. EXPENSE OFFSET

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

                                       21

6. RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS

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

To hedge against adverse interest rate changes, the Fund may invest in financial
futures contracts or municipal bond index 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. Risks may also
arise upon entering into these contracts from the potential inability of the
counterparties to meet the terms of their contracts.

7. SHARES OF BENEFICIAL INTEREST

Transactions in shares of beneficial interest were as follows:

8. 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:

</Table>

As of December 31, 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 discounts on debt
securities and permanent book/tax differences attributable to tax adjustments on
debt securities sold by the Fund. To reflect reclassifications arising from the
permanent differences, accumulated undistributed net investment income was
charged and distributions in excess of net realized gain was credited $31,644.

9. 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, 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 NEW YORK TAX-FREE INCOME FUND

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of
Morgan Stanley New York Tax-Free Income Fund:

We have audited the accompanying statement of assets and liabilities of Morgan
Stanley New York Tax-Free Income Fund (the "Fund"), including the portfolio of
investments, as of December 31, 2005, and the related statements of operations
for the year then ended and changes in net assets for each of the two years in
the period then ended, and the financial highlights for each of the five years
in the period then ended. These financial statements and financial highlights
are the responsibility of the 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 December 31, 2005, by correspondence with the
custodian and brokers; where replies were not received from brokers, we
performed other auditing procedures. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Morgan
Stanley New York Tax-Free Income Fund as of December 31, 2005, the results of
its operations for the year then ended, the changes in its net assets for each
of the two years in the period then ended, and the financial highlights for each
of the five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

Fund.":

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

Item 3. Audit Committee Financial Expert.

The 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

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
