MARKET CONDITIONS

The markets during this review period saw a substantial amount of data
indicating a stronger economy, including reports of 8.2 percent GDP growth in
the third quarter and 4.1 percent in the fourth. While such robust growth might
typically lead to higher interest rates, rates instead fell during the review
period, primarily reflecting indications from the Federal Reserve Bank Open
Market Committee (the Fed) that it planned to keep the federal funds rate at low
levels "for a considerable period." The Fed remained concerned by a lack of job
growth, and investors remained deeply concerned about terrorism and other
potentially deflationary forces.

Against this backdrop, sector performance varied considerably. Falling interest
rates were most clearly expressed in the Treasury market, which saw a
significant rally, especially in September. A combination of improving economic
conditions, broad-based profit growth and increased liquidity buoyed the credit
markets, which saw yield spreads over Treasuries compress during the six-month
period. Investors' increasing appetite for risk led to substantial
outperformance by lower-rated issues, with BBB-rated debt outpacing the
highest-quality bonds by more than 300 basis points. The mortgage-backed
securities (MBS) market lagged during the period as falling interest rates and
continued high levels of homeowner refinancing undercut the sector's
performance.

PERFORMANCE ANALYSIS

Morgan Stanley Quality Income Trust outperformed its primary benchmark, the
Lehman Brothers Intermediate U.S. Government/Credit Index (the "Lehman Index"),
but underperformed the Lipper BBB Rated Funds Index (the "Lipper Index"). The
Fund's corporate bond holdings contributed positively to performance relative to
the Lehman Index. However, relative to the Lipper Index, the fund, on average,
tends to invest in somewhat higher quality debt securities which did not perform
as well as lower rated debt securities. Both sector and issue selection also
benefited the Fund's performance. We used our quantitative risk model and
fundamental research to initiate several new positions to increase the credit
sensitivity of the Fund. During the period, the Fund benefited from a strong
position in the insurance sector, which we felt to be one of the few
high-quality areas of the market that still offered good value. We also
deemphasized the banking and food and beverage sectors, both of which
underperformed the market during the period. The Fund's MBS holdings proved less
beneficial to performance. Our analysis indicated that higher-coupon MBSs were
being unfairly penalized because of unrealistically high prepayment
expectations. As a result, we focused the Fund's MBS holdings in such
securities, only to see them lose ground in the Treasury rally as investors
priced in expectations for even faster prepayments. While these securities did
prepay quickly,

                                        2
<Page>

they did not do so as quickly as the market had expected, and we maintained our
position throughout the period.

Based on our analysis of the economy and the yield curve, we chose to maintain a
relatively low level of interest-rate sensitivity in anticipation of higher
rates once job growth materializes. We implemented this strategy by
deemphasizing the five-year portion of the yield curve. This stance limited the
Fund's interest-rate sensitivity during a period of generally falling rates,
causing it to miss much of the rally in the five-year section of the curve.

Notes on Performance

(1)  The Lehman Brothers Intermediate U.S. Government/Credit Index tracks the
     performance of U.S. government and corporate obligations, including U.S.
     government agency and Treasury securities, and corporate and Yankee bonds
     with maturities of 1 to 10 years. Indexes are unmanaged and their returns
     do not include any sales charges or fees. Such costs would lower
     performance. It is not possible to invest directly in an index.

(2)  The Lipper BBB Rated Funds Index is an equally weighted performance index
     of the largest qualifying funds (based on net assets) in the Lipper BBB
     Rated Funds classification. The Index, which is adjusted for capital gains
     distributions and income dividends, is unmanaged and should not be
     considered an investment. There are currently 30 funds represented in this
     Index.

(3)  Figure shown assumes reinvestment of all distributions and does not reflect
     the deduction of any sales charges.

(4)  Figure shown assumes reinvestment of all distributions and the deduction of
     the maximum applicable sales charge. See the Fund's current prospectus for
     complete details on fees and sales charges.

*    The maximum front-end sales charge for Class A is 4.25%.

**   The maximum contingent deferred sales charge (CDSC) for Class B is 5.0%.
     The CDSC declines to 0% after six years.

+    The maximum contingent deferred sales charge for Class C is 1% for shares
     redeemed within one year of purchase.

++   Class D has no sales charge.

MORGAN STANLEY QUALITY INCOME TRUST

NOTES TO FINANCIAL STATEMENTS - FEBRUARY 29, 2004 (UNAUDITED)

1. ORGANIZATION AND ACCOUNTING POLICIES
Morgan Stanley Quality Income Trust (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 high
current income consistent with safety of principal. The Fund seeks to achieve
its objective by investing at least 80% of its assets in investment grade fixed
income securities. The Fund was organized as a Massachusetts business trust on
September 1, 1988 and commenced operations on May 3, 1989. 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 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) 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) when
market quotations are not readily available or Morgan Stanley Investment
Advisors Inc. (the "Investment Manager") 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 (4) 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 Manager, 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

                                       18
<Page>

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 MANAGEMENT AGREEMENT
Pursuant to an Investment Management Agreement, the Fund pays the Investment
Manager a management fee, calculated 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% to the portion of daily net assets not exceeding
$500 million; 0.50% to the portion of daily net assets exceeding $500 million
but not exceeding $750 million; 0.40% to the portion of the daily net assets
exceeding $750 million but not exceeding $1 billion; and 0.30% to the portion of
the daily net asset exceeding $1 billion.

                                       19

3. PLAN OF DISTRIBUTION
Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the
"Distributor"), an affiliate of the Investment Manager. 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 -- 0.85% 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 0.85% 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 such excess amounts totaled $5,337,949
at February 29, 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 0.85% 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 six months ended February 29, 2004, the distribution fee was accrued for
Class A shares and Class C shares at the annual rate of 0.25% and 0.85%,
respectively.

The Distributor has informed the Fund that for the six months ended February 29,
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 $16,411,
$100,470 and $3,484, respectively and received $14,516 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/prepayments of portfolio
securities, excluding short-term investments, for the six months ended February
29, 2004, aggregated $162,196,829, and $193,525,584, respectively.

Morgan Stanley Trust, an affiliate of the Investment Manager and Distributor, is
the Fund's transfer agent. At February 29, 2004, the Fund had transfer agent
fees and expenses payable of approximately $57,000.

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.
Aggregate pension costs for the six months ended February 29, 2004 included in
Trustees' fees and expenses in the Statement of Operations amounted to $3,598.
At February 29, 2004, the Fund had an accrued pension liability of $60,051 which
is included in accrued expenses in the Statement of Assets and Liabilities.

On December 2, 2003, the Trustees voted to close the plan to new participants,
eliminate the future benefits growth due to increases to compensation after July
31, 2003 and effective April 1, 2004, establish an unfunded deferred
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
throughout the year.

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 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.

As of August 31, 2003, the Fund had a net capital loss carryforward of
$7,215,096 of which $312,541 will expire on August 31, 2004, $2,351,266 will
expire on August 31, 2005, $199,882 will expire on August 31, 2006, $1,146,203
will expire on August 31, 2008, $2,891,735 will expire on August 31, 2009 and
$313,469 will expire on August 31, 2010 to offset future capital gains to the
extent provided by regulations.

                                       21
<Page>

As of August 31, 2003, 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), mark-to-market of open futures contracts and book
amortization of premiums on debt securities.

7. PURPOSES OF RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS
The Fund may enter into forward contracts to facilitate settlement of foreign
currency denominated portfolio transactions or to manage foreign currency
exposure associated with foreign currency denominated securities.

To hedge against adverse interest rate, foreign currency and market risks, the
Fund may purchase and sell interest rate, currency and index futures contracts
("futures contracts").

Forward contracts and futures contracts involve elements of market risk in
excess of the amounts reflected in the Statement of Assets and Liabilities. The
Fund bears the risk of an unfavorable change in the foreign exchange rates
underlying the forward contracts. Risks may also arise upon entering into these
contracts from the potential inability of the counterparties to meet the terms
of their contracts.

8. LEGAL MATTERS
The Investment Manager, certain affiliates of the Investment Manager, certain
officers of such affiliates and certain investment companies advised by the
Investment Manager or its affiliates, including the Fund, are named as
defendants in a number of similar class action complaints which were recently
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 Manager and certain affiliates of
the Investment Manager allegedly offered economic incentives to brokers and
others to recommend to the funds advised by the Investment Manager or its
affiliates rather than funds managed by other companies, and (ii) that the funds
advised by the Investment Manager 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 intend to move to dismiss the action and otherwise vigorously to
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.
