JOINT PROXY STATEMENT

ANNUAL MEETINGS OF SHAREHOLDERS

DECEMBER 18, 2001

This statement is furnished in connection with the solicitation of
proxies by the Boards of Trustees/ Directors (the "Board(s)") of MORGAN
STANLEY DEAN WITTER GOVERNMENT INCOME TRUST ("GVT"), MORGAN STANLEY DEAN
WITTER HIGH INCOME ADVANTAGE TRUST ("YLD"), MORGAN STANLEY DEAN WITTER HIGH
INCOME ADVANTAGE TRUST II ("YLT"), MORGAN STANLEY DEAN WITTER INCOME
SECURITIES INC. ("ICB") and MORGAN STANLEY DEAN WITTER MUNICIPAL INCOME
OPPORTUNITIES TRUST ("OIA") (individually, a "Fund" and, collectively, the
"Funds") for use at the Annual Meetings of Shareholders of the Funds to be
held jointly on December 18, 2001 (the "Meeting(s)"), and at any adjournments
thereof. The first mailing of this Proxy Statement is expected to be made on
or about October , 2001.

If the enclosed form of proxy is properly executed and returned in time
to be voted at the Meetings, the proxies named therein will vote the
shares/stock ("shares") represented by the proxy in accordance with the
instructions marked thereon. Unmarked proxies will be voted for each of the
nominees for election as Trustee/Director to be elected by shareholders with
respect to each Fund, and in favor of Proposal 2 for ICB and in favor of
Proposal 3 for GVT set forth in the attached Notice of Annual Meetings of
Shareholders. A proxy may be revoked at any time prior to its exercise by any
of the following: written notice of revocation to the Secretary of the Funds,
execution and delivery of a later dated proxy to the Secretary of the Funds
(whether by mail or, as discussed below, by touchtone telephone or the
Internet) (if returned and received in time to be voted), or attendance and
voting at the Meetings. Attendance at the Meetings will not in and of itself
revoke a proxy.

Shareholders of record ("Shareholders") of each Fund as of the close of
business on October 23, 2001, the record date for the determination of
Shareholders entitled to notice of and to vote at the Meetings (the "Record
Date"), are entitled to one vote for each share held and a fractional vote for
a fractional share. On October 23, 2001, there were shares of beneficial
interest of GVT, shares of beneficial interest of YLD, shares of beneficial
interest of YLT, shares of common stock of ICB and shares of beneficial
interest of OIA outstanding, all with $0.01 par value. No person was known to
own as much as 5% of the outstanding shares of any of the Funds on that date.
The percentage ownership of shares of each Fund changes from time to time
depending on purchases and sales by Shareholders and the total number of
shares outstanding.

The cost of soliciting proxies for the Meeting of each Fund, consisting
principally of printing and mailing expenses, will be borne by each respective
Fund. The solicitation of proxies will be by mail, which may be supplemented
by solicitation by mail, telephone or otherwise through Trustees/Directors,
officers of the Funds, or officers and regular employees of Morgan Stanley
Investment Advisors Inc. ("Morgan Stanley Investment Advisors" or the
"Investment Manager"), Morgan Stanley Dean Witter Trust FSB ("Morgan Stanley
Trust" or the "Transfer Agent"), Morgan Stanley Services Company Inc. ("Morgan
Stanley Services") and/or Morgan Stanley DW Inc. ("Morgan Stanley DW"),
without special compensation therefor. In addition, each Fund may employ Alamo
Direct Mail Services Inc. ("Alamo") as proxy solicitor, the cost of which is
not expected to exceed $3,000 for each Fund and will be borne by each
respective Fund.

Shareholders will be able to vote their shares by touchtone telephone or
by Internet by following the instructions on the proxy card or on the Voting
Information Card accompanying this Proxy Statement. To vote by Internet or by
telephone, Shareholders can access the website or call the toll-free number
listed on the proxy card or noted in the enclosed voting instructions. To vote
by Internet or by telephone, Shareholders will need the "control number" that
appears on the proxy card.

In certain instances, Alamo and Morgan Stanley Trust may call
Shareholders to ask if they would be willing to have their votes recorded by
telephone. The telephone voting procedure is designed to authenticate
Shareholders' identities, to allow Shareholders to authorize the voting of
their shares in accordance with their instructions and to confirm that their
instructions have been recorded properly. No recommendation will be made as to
how a Shareholder should vote on any Proposal other than to refer to the
recommendations of the Board. The Funds have been advised by counsel that
these procedures are consistent with the requirements of applicable law.
Shareholders voting by telephone in this manner will be asked for their social
security number or other identifying information and will be given an
opportunity to authorize proxies to vote their shares in accordance with their
instructions. To ensure that the Shareholders' instructions have been recorded
correctly they will receive a confirmation of their instructions in the mail.
A special toll-free number set forth in the confirmation will be available in
case the information contained in the confirmation is incorrect. Although a
Shareholder's vote may be taken by telephone, each Shareholder will receive a
copy of this Proxy Statement and may vote by mail using the enclosed proxy
card or by touchtone telephone or the Internet as set forth above. The last
proxy vote received in time to be voted, whether by proxy card, touchtone
telephone or Internet, will be the last vote that is counted and will revoke
all previous votes by the Shareholder. With respect to the solicitation of a
telephonic vote by Alamo, additional expenses would include $7.00 per
telephone vote transacted, $3.00 per outbound telephone contact and costs
relating to obtaining Shareholders' telephone numbers, which would be borne by
each respective Fund.

(1) ELECTION OF TRUSTEES/DIRECTORS FOR EACH FUND

The number of Trustees/Directors of each Fund has been fixed by the
Trustees/Directors, pursuant to each Fund's Declaration of Trust or Articles
of Incorporation, at nine. There are presently nine Trustees/Directors for
each Fund. At the Meetings, the following nominees are to be elected to each
Fund's Board of Trustees/Directors to serve for the following terms, in
accordance with each Fund's Declaration of Trust or Articles of Incorporation,
as set forth below:

YLD -- ICB --
GVT, YLT, OIA Until the year 2004 Until the year 2002
Until the year 2004 Annual Meeting Annual Meeting Annual Meeting
------------------------------------ ------------------------ -----------------------

Edwin J. Garn Michael Bozic Michael Bozic
Michael E. Nugent Charles A. Fiumefreddo Charles A. Fiumefreddo
Philip J. Purcell James F. Higgins Edwin J. Garn
Wayne E. Hedien
James F. Higgins
Manuel H. Johnson
Michael E. Nugent
Philip J. Purcell
John L. Schroeder

Six of the current nine Trustees/Directors (Michael Bozic, Edwin J. Garn,
Wayne E. Hedien, Manuel H. Johnson, Michael E. Nugent and John L. Schroeder)
are "Independent Trustees" or "Independent Directors," that is, Trustees or
Directors who are not "interested persons" of the Funds, as that term is
defined in the Investment Company Act of 1940, as amended (the "1940 Act").
The other three current Trustees/Directors, Charles A. Fiumefreddo, James F.
Higgins and Philip J. Purcell, are "interested persons" (as that term is
defined in the 1940 Act) of the Funds and Morgan Stanley Investment Advisors
and thus, are not Independent Trustees or Independent Directors. The nominees
for election as Trustee or Director have been proposed by the Trustees or
Directors now serving, or in the case of the nominees for positions as
Independent Trustee or Independent Director, by the Independent Trustees or
Independent Directors now serving. All of the members of the Boards previously
have been elected by the Shareholders of the Funds.

The nominees of the Boards of Trustees/Directors for election as
Trustee/Director are listed below. It is the intention of the persons named in
the enclosed form of proxy, unless instructed by proxy to withhold authority
to vote for the nominees, to vote all validly executed proxies for the
election of these nominees: for GVT, YLT and OIA--Edwin J. Garn, Michael E.
Nugent and Philip J. Purcell; for YLD--Michael Bozic, Charles A. Fiumefreddo
and James F. Higgins; for ICB--Michael Bozic, Charles A. Fiumefreddo, Edwin J.
Garn, Wayne E. Hedien, James F. Higgins, Manuel H. Johnson, Michael E. Nugent,
Philip J. Purcell and John L. Schroeder. Should any of the nominees become
unable or unwilling to accept nomination or election, the persons named in the
proxy will exercise their voting power in favor of such person or persons as
the Boards may recommend or, in the case of an Independent Trustee/Director
nominee, as the Independent Trustees/Directors of each Fund may recommend. All
of the nominees have consented to being named in this Proxy Statement and to
serve if elected. The Funds know of no reason why any of the said nominees
would be unable or unwilling to accept nomination or election. With respect to
each Fund, the election of each Trustee/Director requires the approval of a
majority of the shares of the Fund represented and entitled to vote at the
Meeting.

Pursuant to the provisions of the Declaration of Trust of each of GVT,
YLD, YLT, and OIA, in certain cases as amended, the Trustees are divided into
three separate classes, each class having a term of three years. The term of
office of one of each of the three classes will expire each year.

The Boards of GVT, YLD, YLT and OIA previously determined that any
nominee for election as Trustee for each Fund will stand for election as
Trustee and serve as Trustee in one of the three classes of Trustees as
follows: Class I--Messrs. Bozic, Fiumefreddo and Higgins; Class II--Messrs.
Hedien, Johnson and Schroeder; and Class III--Messrs. Garn, Nugent and
Purcell. Each nominee will, if elected, serve a term of up to approximately
three years running for the period assigned to that class and terminating at
the date of the Annual Meeting of Shareholders so designated by the Boards, or
any adjournments thereof. In accordance with the above, the Trustees in Class
III for GVT, YLT and OIA and the Trustees in Class I for YLD are standing for
election and will, if elected, serve until the year 2004 Annual Meeting for
each Fund as set forth above, or in each case, until his successor has been
elected and qualified. As a consequence of this method of election, the
replacement of a majority of each of the Boards could be delayed for up to two
years.

Pursuant to the provisions of the Articles of Incorporation of ICB, the
terms of office of each Director will expire each year. Therefore, all of the
Directors of the Fund, if elected, will serve until the year 2002 Annual
Meeting of ICB, or until their successors shall have been elected and
qualified.

The following information regarding the nominees for election as
Trustee/Director, and each of the other members of the Boards, includes his
principal occupations and employment for at least the last five years, his
age, shares of each Fund owned, if any, as of October 23, 2001 (shown in
parentheses), positions with the Funds, and directorships or trusteeships in
companies which file periodic reports with the Securities and Exchange
Commission, including the 98 investment companies, including the Funds, for

THE BOARD OF TRUSTEES/DIRECTORS, THE INDEPENDENT TRUSTEES/DIRECTORS, AND THE
COMMITTEES

The Board currently consists of nine (9) Trustees/Directors. These same
individuals also serve as directors or trustees for all of the Morgan Stanley
Funds, and are referred to in this section as Trustees. As of the date of this
Proxy Statement, there are a total of Morgan Stanley Dean Witter Funds,
comprised of portfolios. As of September 30, 2001, the Morgan Stanley Funds
had total net assets of approximately $ billion and more than six million
shareholders.

Six Trustees (67% of the total number) have no affiliation or business
connection with Morgan Stanley Investment Advisors or any of its affiliated
persons and do not own stock or other securities issued by Morgan Stanley
Investment Advisors' parent company, Morgan Stanley. These are the
"disinterested" or "independent" Trustees.

Law and regulation establish both general guidelines and specific duties
for the Independent Trustees. The Morgan Stanley Funds seek as Independent
Trustees individuals of distinction and experience in business and finance,
government service or academia; these are people whose advice and counsel are
in demand by others and for whom there is often competition. To accept a
position on the Funds' Boards, such individuals may reject other attractive
assignments because the Funds make substantial demands on their time. All of
the Independent Trustees serve as members of the Audit Committee. In addition,
three of the Trustees/Directors, including two Independent Trustees, serve as
members of the Derivatives Committee and the Insurance Committee. The Funds do
not have any nominating or compensation committees.

The Independent Trustees are charged with recommending to the full Board
approval of management, advisory and administration contracts, and
distribution and underwriting agreements; continually reviewing Fund
performance; checking on the pricing of portfolio securities, brokerage
commissions, transfer agent costs and performance, and trading among Funds in
the same complex; and approving fidelity bond and related insurance coverage
and allocations, as well as other matters that arise from time to time.

The Audit Committee is charged with recommending to the full Board the
engagement or discharge of the Funds' independent auditors; directing
investigations into matters within the scope of the independent auditors'
duties, including the power to retain outside specialists; reviewing with the
independent auditors the audit plan and results of the auditing engagement;
approving professional services provided by the independent auditors and other
accounting firms prior to the performance of such services; reviewing the
independence of the independent auditors; considering the range of audit and
non-audit fees; reviewing the adequacy of the Fund's system of internal
controls; and preparing and submitting Committee meeting minutes to the full
Board. All of the members of the Audit Committee are independent as defined in
the New York Stock Exchange Corporate Governance Standards for audit
committees.

The Board of each Fund has formed a Derivatives Committee to approve
parameters for and monitor the activities of the Fund with respect to
derivative investments, if any, made by such Fund. Finally, the Board of each
Fund has formed an Insurance Committee to review and monitor the insurance
coverage maintained by the Funds.

The following chart sets forth the number of meetings of the Board, the
Audit Committee, the Independent Trustees, the Derivatives Committee and the
Insurance Committee of each Fund during its most recent fiscal year. No
Trustee attended fewer than 75% of the meetings of the Board, the Audit
Committee, the Independent Trustees, the Derivatives Committee or the
Insurance Committee held while he served in such positions.

responsibilities. A copy of the Audit Committee charter is attached to this
Proxy Statement as Exhibit A.

The Audit Committee of each Fund has reviewed and discussed the financial
statements of each Fund with management as well as with Deloitte & Touche LLP,
the independent auditors for each Fund. In the course of its discussions, the
Audit Committee also discussed with Deloitte & Touche LLP any relevant matters
required to be discussed under Statement on Auditing Standards No. 61. Based
on this review, the Audit Committee recommended to the Board of
Trustees/Directors of each Fund that each Fund's audited financial statements
be included in each Fund's Annual Report to Shareholders for the most recent
fiscal year for filing with the Securities and Exchange Commission. The Audit
Committee has received the written disclosures and the letter from Deloitte &
Touche LLP required under Independence Standards Board No. 1 and has discussed
with the independent auditors their independence.

ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT TRUSTEES/DIRECTORS FOR ALL
MORGAN STANLEY FUNDS

The Independent Trustees/Directors and the Funds' management believe that
having the same Independent Trustees/Directors for each of the Morgan Stanley
Funds avoids the duplication of effort that would arise from having different
groups of individuals serving as Independent Trustees/Directors for each of
the Funds or even of sub-groups of Funds. They believe that having the same
individuals serve as Independent Trustees/ Directors of all the Funds tends to
increase their knowledge and expertise regarding matters which affect the Fund
complex generally and enhances their ability to negotiate on behalf of each
Fund with the Fund's service providers. This arrangement also precludes the
possibility of separate groups of Independent Trustees/ Directors arriving at
conflicting decisions regarding operations and management of the Funds and
avoids the cost and confusion that would likely ensue. Finally, having the
same Independent Trustees/Directors serve on all Fund Boards enhances the
ability of each Fund to obtain, at modest cost to each separate Fund, the
services of Independent Trustees/Directors of the caliber, experience and
business acumen of the individuals who serve as Independent Trustees/Directors
of the Morgan Stanley Funds.

SHARE OWNERSHIP BY TRUSTEES/DIRECTORS

The Trustees/Directors have adopted a policy pursuant to which each
Trustee/Director and/or his or her spouse is required to invest at least
$25,000 in any of the Funds in the Morgan Stanley Funds complex on whose
boards the Trustee/Director serves. In addition, the policy contemplates that
the Trustees/Directors will, over time, increase their aggregate investment in
the Funds above the $25,000 minimum requirement. The Trustees/Directors may
allocate their investments among specific Funds in any manner they determine
is appropriate based on their individual investment objectives. As of the date
of this Proxy Statement, each Trustee/Director is in compliance with the
policy. Any future Trustee/Director will be given a one year period following
his or her election within which to comply with the foregoing. As of September
30, 2001, the total value of the investments by the Trustees/Directors and/or
their spouses in shares of the Morgan Stanley Funds was approximately $
million.

As of the record date for these Meetings, the aggregate number of shares
of each Fund owned by the Fund's officers and Trustees/Directors as a group
was less than 1 percent of each Fund's outstanding shares.

COMPENSATION OF INDEPENDENT TRUSTEES/DIRECTORS

Each Fund pays each Independent Trustee/Director an annual fee of $800
plus a per meeting fee of $50 for meetings of the Board of Trustees/Directors,
the Independent Trustees/Directors or committees of the Board attended by the
Trustee/Director (each Fund pays the Chairman of the Audit Committee an
additional annual fee of $750 and the Chairmen of the Derivatives and
Insurance Committees additional annual fees of $500). If a Board meeting and a
meeting of the Independent Trustees/Directors or a Committee meeting, or a
meeting of the Independent Trustees/Directors and/or more than one Committee
meeting, take place on a single day, the Trustees/Directors are paid a single
meeting fee by each Fund. Each Fund also reimburses such Trustees/Directors
for travel and other out-of-pocket expenses incurred by them in connection
with attending such meetings. Trustees/Directors and officers of the Funds who
are or have been employed by the Investment Manager or an affiliated company
receive no compensation or expense reimbursement from the Funds for their
services as Trustee/Director.

As of the date of this Proxy Statement, 53 of the Morgan Stanley Funds,
including each of the Funds represented in this Proxy Statement, have adopted
a retirement program under which an Independent Trustee/Director who retires
after serving for at least five years (or such lesser period as may be
determined by the Board) as an Independent Director or Trustee of any Morgan
Stanley Fund that has adopted the retirement program (each such Fund referred
to as an "Adopting Fund" and each such Trustee/Director referred to as an
"Eligible Trustee/Director") is entitled to retirement payments upon reaching
the eligible retirement age (normally, after attaining age 72). Annual
payments are based upon length of service. Currently, upon retirement, each
Eligible Trustee/Director is entitled to receive from each Adopting Fund,
commencing as of his or her retirement date and continuing for the remainder
of his or her life, an annual retirement benefit (the "Regular Benefit") equal
to 30.22% of his or her Eligible Compensation plus 0.5036667% of such Eligible
Compensation for each full month of service as an Independent Director or
Trustee of any Adopting Fund in excess of five years up to a maximum of 60.44%
after ten years of service. The foregoing percentages may be changed by the
Board. "Eligible Compensation" is one-fifth of the total compensation earned
by such Eligible Trustee/Director for service to the Adopting Fund in the five
year period prior to the date of the Eligible Trustee's/Director's retirement.
An Eligible Trustee/Director may elect alternate payments of his or her
retirement benefits based upon the combined life expectancy of such Eligible
Trustee/Director and his or her spouse on the date of such Eligible
Trustee's/Director's retirement. The amount estimated to be payable under this
method, through the remainder of the later of the lives of such Eligible
Trustee/Director and spouse, will be the actuarial equivalent of the Regular
Benefit. In addition, the Eligible Trustee/Director may elect that the

surviving spouse's periodic payment of benefits will be equal to a lower
percentage of the periodic amount when both spouses were alive. Benefits under
the retirement program are accrued as expenses on the books of the Funds. Such
benefits are not secured or funded by the Adopting Funds.

The following tables illustrate the compensation paid to each Fund's
Independent Trustees/Directors by each Fund for its last fiscal year, and the
retirement benefits accrued to each Fund's Independent Trustees/ Directors by
the Fund for its last fiscal year and the estimated retirement benefits for
the Fund's Independent Trustees/Directors, to commence upon their retirement,
as of the end of the Fund's last fiscal year.

SHAREHOLDERS VOTE FOR THE ELECTION OF EACH OF THE TRUSTEES/DIRECTORS NOMINATED
FOR ELECTION.

(2) APPROVAL OR DISAPPROVAL OF CHANGE OF NAME OF
MORGAN STANLEY DEAN WITTER INCOME SECURITIES INC.
TO MORGAN STANLEY INCOME SECURITIES INC.

The management of Morgan Stanley Investment Advisors has recommended to
the Board of Directors of the Fund that the name of the Fund be changed to
"Morgan Stanley Income Securities Inc." in view of recent changes, including
the name change of the Investment Manager/Advisor, Morgan Stanley Dean Witter
Advisors Inc. to Morgan Stanley Investment Advisors Inc. on June 18, 2001, and
the recent and forthcoming name changes of most of the Morgan Stanley Funds to
include only the brand name of "Morgan Stanley." The Board of Directors and
the Fund's management believe that changing the Fund's name to "Morgan Stanley
Income Securities Inc." would reflect more accurately the association with
Morgan Stanley Investment Advisors and Morgan Stanley, the parent company of
Morgan Stanley Investment Advisors.

The Board of Directors has considered the proposal and believes it to be
in the best interest of the Fund and its stockholders to change the name of
the Fund to "Morgan Stanley Income Securities Inc." To effect such

a change, it is necessary to amend the Fund's Articles of Incorporation, which
requires the approval of stockholders. The favorable vote of the holders of a
majority of the outstanding shares of the Fund is required to approve the
proposed amendment.

THE BOARD OF DIRECTORS OF THE FUND UNANIMOUSLY RECOMMENDS THAT
STOCKHOLDERS VOTE TO APPROVE AN AMENDMENT TO THE FUND'S ARTICLES OF
INCORPORATION TO CHANGE THE NAME OF THE FUND TO "MORGAN STANLEY INCOME
SECURITIES INC."

(3) APPROVAL OR DISAPPROVAL OF AN AMENDMENT TO THE INVESTMENT
RESTRICTIONS OF MORGAN STANLEY DEAN WITTER GOVERNMENT INCOME TRUST

The Fund has certain investment restrictions which are set forth in the
Fund's original prospectus and which are fundamental policies of the Fund.
(The Fund is referred to as the Trust in the investment restrictions.) Under
the Act, a fundamental policy may not be changed without the favorable vote of
a majority of the outstanding voting securities of the Fund, as defined in the
Act. Such a majority is defined as the lesser of (a) 67% or more of the shares
present at the meeting, if the holders of more than 50% of the outstanding
shares of the Fund are present or represented by proxy, or (b) more than 50%
of the outstanding shares.

On October , 2001, the Board of Trustees unanimously approved a
recommendation by the Fund's Investment Manager that the Fund seek
authorization from its shareholders to amend the Fund's investment
restrictions to permit the Fund to invest in financial futures contracts and
related options thereon and options on debt securities. If amended as proposed
the investment restrictions would read as follows: "The Trust may not:

10.Issue senior securities as defined in the Act except insofar as the Trust
may be deemed to have issued a senior security by reason of: (a) entering
into any repurchase or reverse repurchase agreement; (b) borrowing money;
(c) purchasing any securities on a when-issued, delayed delivery or
forward commitment basis; or purchasing or selling any futures contracts
and related options....

17.Purchase or sell commodities or commodities contracts, except that the
Fund may purchase and sell financial futures contracts and related
options."

The Investment Manager proposed the amendments to increase its flexibility
in the management of the Fund's portfolio which may enable it to increase the
yield of the Fund's shares.

FUTURES CONTRACTS AND OPTIONS ON FUTURES

If the shareholders approve the amendments to the investment
restrictions, the Fund would be able to invest in financial futures contracts
("futures contracts") and related options thereon solely for hedging purposes.
The Fund may sell a futures contract or purchase a put option on such futures
contract, if the Investment Manager anticipates interest rates to rise, as a
hedge against a decrease in the value of the Fund's portfolio securities. If
the Investment Manager anticipates that interest rates will decline, the Fund
may purchase a futures contract or a call option thereon to protect against an
increase in the price of the securities the Fund intends to purchase. These
futures contracts and related options thereon will be used only as a hedge
against anticipated interest rate changes. A futures contract sale creates an
obligation by the Fund, as seller, to deliver the specific type of instrument
called for in the contract at a specified future time for a specified price. A
futures contract purchase would create an obligation by the Fund, as
purchaser, to take delivery of the specific type of financial instrument at a
specified future time at a specified price. The specific securities delivered
or taken, respectively, at settlement date, would not be determined until or
near that date. The determination would be in accordance with the rules of the
exchange on which the futures contract sale or purchase was effected.

Although the terms of futures contracts specify actual delivery or
receipt of securities, in most instances the contracts are closed out before
the settlement date without making or taking of delivery of the securities.
Closing out of a futures contract is effected by entering into an off-setting
purchase or sale transaction. An off-setting transaction for a futures
contract sale is effected by the Fund entering into a futures contract
purchase for the same aggregate amount of the specific type of financial
instrument and same delivery date. If the price in the sale exceeds the price
in the off-setting purchase, the Fund is immediately paid the difference and
thus realizes a gain. If the off-setting purchase price exceeds the sale
price, the Fund pays the difference and realizes a loss. Similarly, the
closing out of a futures contract purchase is effected by the Fund entering
into a futures contract sale. If the off-setting sale price exceeds the
purchase price, the Fund realizes a gain, and if the off-setting sale price is
less than the purchase price, the Fund realizes a loss.

If the Fund enters into a futures contract, it is initially required to
deposit an "initial margin" of cash, U.S. government securities or other
liquid portfolio securities ranging from approximately 2% to 5% of the
contract amount. Initial margin requirements are established by the exchanges
on which futures contracts trade and may, from time to time, change. In
addition, brokers may establish margin deposit requirements in excess of those
required by the exchanges.

Initial margin in futures transactions is different from margin in
securities transactions in that initial margin does not involve the borrowing
of funds by a broker's client but is, rather, a good faith deposit on the
futures contract which will be returned to the Fund upon the proper
termination of the futures contract. The margin deposits made are marked to
market daily and the Fund may be required to make subsequent deposits of cash,
U.S. government securities or other liquid portfolio securities, called
"variation margin," which are reflective of price fluctuations in the futures
contract.

A risk in employing futures contracts to protect against the price
volatility of portfolio securities is that the prices of securities subject to
futures contracts may correlate imperfectly with the behavior of the cash
prices of the Fund's portfolio securities.

Another risk is that the Investment Manager could be incorrect in its
expectations as to the direction or extent of various interest rate movements
or the time span within which the movements take place. For example, if the
Fund sold futures contracts for the sale of securities in anticipation of an
increase in interest rates, and then interest rates went down instead, causing
bond prices to rise, the Fund would lose money on the sale and the loss may be
offset by an increase in the value of the underlying securities.

In addition to the risks described below which apply to all options
transactions, there are several special risks relating to options on futures,
in particular, the ability to establish and close out positions on such
options will be subject to the development and maintenance of a liquid
secondary market. It is not certain that this market will develop or be
maintained.

If the Fund is permitted to invest in futures contracts and related
options thereon, it however, may not enter into futures contracts or related
options thereon if immediately thereafter the amount committed to margin plus
the amount paid for option premiums exceeds 5% of the value of the value of
the Fund's total assets, after taking into account unrealized gains and
unrealized losses on such contracts into which it has entered; provided,
however, that in the case of an option that is in-the-money (the exercise
price of the call (put) option is less (more) than the market price of the
underlying security) at the time of purchase, the in-the-money amount may be
excluded in calculating the 5%. However, there is no overall limitation on the
percentage of the Fund's net assets which may be subject to a hedge position.

There is no assurance that a liquid secondary market will exist for
futures contracts and related options in which the Fund may invest. In the
event a liquid market does not exist, it may not be possible to close out a

futures position and, in the event of adverse price movements, the Fund would
continue to be required to make daily cash payments of variation margin. The
absence of a liquid market in futures contracts might cause the Fund to make or
take delivery of the underlying securities at a time when it may be
disadvantageous to do so.

Exchanges also limit the amount by which the price of a futures contract
may move on any day. If the price moves equal the daily limit on successive
days, then it may prove impossible to liquidate a futures position until the
daily limit moves have ceased. In the event of adverse price movements, the
Fund would continue to be required to make daily cash payments of variation
margin on open futures positions. In these situations, if the Fund has
insufficient cash, it may have to sell portfolio securities to meet daily
variation margin requirements at a time when it may be disadvantageous to do
so. In addition, the Fund may be required to take or make delivery of the
instruments underlying interest rate futures contracts it holds at a time when
it is disadvantageous to do so. The inability to close out options and futures
positions could also have an adverse impact on the Fund's ability to
effectively hedge its portfolio.

In considering whether to recommend the adoption of the proposed
amendments, the Board of Trustees took cognizance of the Fund's primary
investment objective to provide as high a level of current income for
distribution to shareholders as is consistent with prudent investment risk and
determined that the increased portfolio management flexibility in terms of
hedging and managing interest rate risk resulting from the adoption of these
amendments would be beneficial to the Fund in attempting to realize its
investment objective. The Trustees also noted that other registered investment
companies with similar investment objectives and policies managed by the
Fund's Investment Manager, have the ability to invest in futures contracts and
options thereon and determined that their investment techniques should also be
made available to the Fund. After evaluating all factors considered relevant
to the matter, including the risks and costs associated with the use of
futures and options, the Board of Trustees unanimously concluded that the
adoption of the amendments would be in the best interest of the Fund and its
shareholders.

A majority of the outstanding voting securities of the Fund is required
in order to approve the amendments to the Fund's investment restrictions. Such
a majority is defined as the affirmative vote of the holders of (a) 67% or
more of the shares of the Fund present, in person or by proxy, at the Meeting,
if the holders of more than 50% of the outstanding shares are so present, or
(b) more than 50% of the outstanding shares of the Fund, whichever is less.

THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS APPROVE THE
PROPOSED AMENDMENTS TO INVESTMENT RESTRICTIONS 10 AND 17.

connection with the annual audit and review of financial statements of GVT,
YLD and ICB for their respective fiscal years ended September 30, 2001, for
YLT for its fiscal year ended July 31, 2001 and for OIA for its fiscal year
ended May 31, 2001 were $26,000, $25,000, $26,000, $26,000 and $26,000,
respectively.

FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES

There were no professional services rendered by Deloitte & Touche LLP to
the Funds, the investment advisor, or affiliated entities that provide
services to the Fund during their most recent fiscal years ended, relating to
financial information systems design and implementation.

ALL OTHER FEES

The aggregate fees for professional services rendered by Deloitte &

advisor and to affiliated entities that provided services to the Funds
amounted to $11.6 million, which fees related to services such as tax and
regulatory consultation, tax return preparation, agreed upon procedures,
compliance and improving business and operational processes.

The Audit Committee of each of the Funds considered whether Deloitte &

their independence.

ADDITIONAL INFORMATION

In the event that the necessary quorum to transact business or the vote
required to approve or reject any proposal for any Fund is not obtained at the
Meetings, the persons named as proxies may propose one or more adjournments of
the Meeting of the applicable Fund to permit further solicitation of proxies.
Any such adjournment will require the affirmative vote of the holders of a
majority of the applicable Fund's shares present in person or by proxy at the
Meeting. The persons named as proxies will vote in favor of such adjournment
those proxies which have been received by the date of the Meeting.

Abstentions and, if applicable, broker "non-votes" will not count as
votes in favor of any of the proposals, and broker "non-votes" will not be
deemed to be present at the Meeting of any Fund for purposes of determining
whether a particular proposal to be voted upon has been approved. Broker
"non-votes" are shares held in street name for which the broker indicates that
instructions have not been received from the beneficial owners or other
persons entitled to vote and for which the broker does not have discretionary
voting authority.

INTEREST OF CERTAIN PERSONS

Morgan Stanley, Morgan Stanley Investment Advisors, Morgan Stanley DW,
Morgan Stanley Services, and certain of their respective Directors, Officers,
