                        ANNUAL MEETINGS OF SHAREHOLDERS
                               DECEMBER 17, 1998

   This statement is furnished in connection with the solicitation of proxies
by the Boards of Trustees/ Directors (the "Board(s)") of DEAN WITTER
GOVERNMENT INCOME TRUST ("DWGIT"), HIGH INCOME ADVANTAGE TRUST ("HIAT"), HIGH
INCOME ADVANTAGE TRUST II ("HIAT II"), INTERCAPITAL INCOME SECURITIES INC.
("ICIS") and MUNICIPAL INCOME OPPORTUNITIES TRUST ("MIOT") (individually, a
"Fund" and, collectively, the "Funds") for use at the Annual Meetings of
Shareholders of the Funds to be held jointly on December 17, 1998 (the
"Meeting(s)"), and at any adjournments thereof. The first mailing of this
Proxy Statement is expected to be made on or about November 5, 1998.

   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, and, with respect to ICIS,
Proposal 3 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
(if returned and received in time to be voted), or attendance and voting at
the Annual Meetings of Shareholders. 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 28, 1998, the record date for the determination of
Shareholders entitled to notice of and to vote at the Meetings, are entitled to
one vote for each share held and a fractional vote for a fractional share. On
October 28, 1998, there were 43,309,400 shares of beneficial interest of DWGIT,
30,017,252 shares of beneficial interest of HIAT, 35,611,307 shares of
beneficial interest of HIAT II, 11,845,218 shares of common stock of ICIS and
21,089,872 shares of beneficial interest of MIOT 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.

                                       2

   The cost of soliciting proxies for these Annual Meetings of Shareholders
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 Dean Witter Advisors Inc. ("MSDW
Advisors" or the "Investment Manager") (formerly named Dean Witter
InterCapital Inc.), Morgan Stanley Dean Witter Trust FSB ("MSDW Trust"),
Morgan Stanley Dean Witter Services Company Inc. ("MSDW Services") and/or
Dean Witter Reynolds Inc. ("DWR"), without special compensation therefor. In
addition, each Fund may employ William F. Doring & Co. 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.

   William F. Doring & Co. and MSDW 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 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 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. With respect to the
solicitation of a telephonic vote by William F. Doring & Co., 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.

                                                                        Wayne E. Hedien
                                                                        Manuel H. Johnson
                                                                        Michael E. Nugent
                                                                        Philip J. Purcell
                                                                        John L. Schroeder


   Seven of the current nine Trustees/Directors (Michael Bozic, Edwin J.
Garn, John R. Haire, 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 two current Trustees/Directors, Charles A.
Fiumefreddo and Philip J. Purcell, are "interested persons" (as that term is
defined in the 1940 Act) of the Funds and MSDW 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 Trustee/Director, by
the Independent Trustees or Independent Directors now serving. All of the
members of the Boards currently serving have been elected previously 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 DWGIT, HIAT II and MIOT--Edwin J. Garn, John R. Haire,
Michael E. Nugent and Philip J. Purcell; for HIAT--Michael Bozic and Charles A.
Fiumefreddo; for ICIS--Michael Bozic, Charles A. Fiumefreddo, Edwin J. Garn,
John R. Haire, Wayne E. Hedien, Manuel H. Johnson, Michael E. Nugent, Philip J.
Purcell and John L. Schroeder. Should 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.

                                       4

   Pursuant to the provisions of the Declaration of Trust of each of DWGIT,
HIAT, HIAT II, and MIOT, 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 DWGIT, HIAT, HIAT II and MIOT 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 and Fiumefreddo; Class II--Messrs. Hedien,
Johnson and Schroeder; and Class III--Messrs. Garn, Haire, Nugent and
Purcell. Any 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 DWGIT, HIAT II and MIOT and the Trustees in Class I for HIAT
are standing for election and will, if elected, serve until the year 2001
Annual Meetings for each Fund as set forth above, or until their successors
shall have 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 ICIS, 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 1999 Annual Meeting
of ICIS, 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 28, 1998 (shown in

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
Dean Witter Funds, and are referred to in this section as Trustees. As of the
date of this Proxy Statement, there are a total of 85 Morgan Stanley Dean
Witter Funds, comprised of 121 portfolios. As of September 30, 1998, the
Morgan Stanley Dean Witter Funds had total net assets of approximately $105.3
billion and more than six million shareholders.

   Seven Trustees (77% of the total number) have no affiliation or business
connection with MSDW Advisors or any of its affiliated persons and do not own
stock or other securities issued by MSDW Advisors' parent company, MSDW.
These are the "disinterested" or "independent" Trustees. Four of the seven
Independent Trustees are also Independent Trustees of the TCW/DW Funds.

   Law and regulation establish both general guidelines and specific duties
for the Independent Trustees. The Morgan Stanley Dean Witter 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

                                       7

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. Indeed,
by serving on the Funds' Boards, certain Trustees who would otherwise be
qualified and in demand to serve on bank boards would be prohibited by law
from doing so.

   All of the Independent Trustees serve as members of the Audit Committee.
Three of them also serve as members of the Derivatives Committee. In
addition, three of the Trustees, including two Independent Trustees, serve as
members of the Insurance Committee.

   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 accountants; directing
investigations into matters within the scope of the independent accountants'
duties, including the power to retain outside specialists; reviewing with the
independent accountants the audit plan and results of the auditing
engagement; approving professional services provided by the independent
accountants and other accounting firms prior to the performance of such
services; reviewing the independence of the independent accountants;
considering the range of audit and non-audit fees; and reviewing the adequacy
of the Fund's system of internal controls.

   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 the Fund.

   Finally, the Board of each Fund has formed an Insurance Committee to
review and monitor the insurance coverage maintained by the Fund.

   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 or the Derivatives Committee held while
he served in such positions.

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

   The Independent Trustees/Directors and the Funds' management believe that
having the same Independent Trustees/Directors for each of the Morgan Stanley
Dean Witter 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

                                8


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 Dean Witter 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 Dean Witter Funds complex
(and, if applicable, in the TCW/DW 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 the date
of this Proxy Statement, the total value of the investments by the
Trustees/Directors and/or their spouses in shares of the Morgan Stanley Dean
Witter Funds (and, if applicable, the TCW/DW Funds) was approximately $25.3
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). 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. Mr. Haire currently serves as Chairman of
the Audit Committee. Prior to June 1, 1998, Mr. Haire also served as Chairman
of the Independent Trustees/Directors, for which services each Fund paid him
an additional annual fee of $1,200.

   As of the date of this Proxy Statement, 57 of the Morgan Stanley Dean
Witter 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 Dean Witter 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 29.41% of his or
her Eligible Compensation plus

                                       9

0.4901667% 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 58.82% 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 either 50% or 100% of the previous periodic amount,
an election that, respectively, increases or decreases the previous periodic
amount so that the resulting payments will be the actuarial equivalent of the
Regular Benefit. Benefits under the retirement program 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.

THE INVESTMENT MANAGER OR INVESTMENT ADVISER AND THE INVESTMENT MANAGEMENT
(ADVISORY) AGREEMENTS

   MSDW Advisors currently serves as investment manager or investment adviser
of each Fund pursuant to an investment management agreement or investment
advisory agreement entered into by each Fund and MSDW Advisors dated May 31,
1997 (each, an "Agreement" and collectively, the "Agreements"), which took
effect upon the consummation of the merger of Dean Witter, Discover & Co.
with Morgan Stanley Group Inc. The Agreements were approved by the Board of
Trustees/Directors on February 21, 1997, and by the shareholders of each Fund
at a Special Meeting of Shareholders held on May 20, 1997. The Agreements
supersede earlier management and advisory agreements originally entered into
by the Funds and MSDW Advisors and are identical in all material respects,
including fees payable by a Fund thereunder, to the earlier management and
advisory agreements, except for dates of effectiveness and termination.

THE INVESTMENT MANAGEMENT AGREEMENTS

   Each Agreement of DWGIT, HIAT, HIAT II and ICIS (in this section, each
"Fund" refers to each of DWGIT, HIAT, HIAT II and ICIS) provides that MSDW
Advisors shall obtain and evaluate such information and advice relating to
the economy and securities and commodity markets as it deems necessary or
useful to discharge its duties under the respective Agreements, and that it
shall continuously supervise the management of the assets of each Fund in a
manner consistent with the investment objectives and policies of that Fund
and subject to such other limitations and directions as the Board of the Fund
may, from time to time, prescribe.

   MSDW Advisors pays the compensation of the officers of each Fund who are
also directors, officers or employees of the Investment Manager and provides
the Fund with office space and equipment, and clerical and bookkeeping
services and telephone service, heat, light, power and other utilities. MSDW
Advisors also pays for the services of personnel in connection with the
pricing of the Fund's shares and the preparation of prospectuses, proxy
statements and reports required to be filed with federal and state securities
commissions (except insofar as the participation or assistance of independent
accountants and attorneys is, in the opinion of MSDW Advisors, necessary or
desirable). In return for its services and the expenses MSDW Advisors assumes
under the Agreements, each Fund pays MSDW Advisors compensation which is
computed and accrued weekly and payable monthly and which is determined by
applying the following annual rate to each Fund's average weekly net assets
as set forth in the table below:



                                                                               MANAGEMENT

THE INVESTMENT MANAGER OR INVESTMENT ADVISER

   Morgan Stanley Dean Witter Advisors Inc. is each Fund's investment manager
or investment advisor. MSDW Advisors maintains its offices at Two World Trade

July, 1992 under the name Dean Witter InterCapital Inc., changed its name to
Morgan Stanley Dean Witter Advisors on June 22, 1998. MSDW Advisors is a
wholly-owned subsidiary of MSDW, a preeminent global securities firm that

the consolidated financial position of the company.

   MSDW Advisors and its wholly-owned subsidiary, MSDW Services, serve in
various investment management, advisory, management and administrative
capacities to investment companies and pension plans and other institutional

   MSDW Advisor's wholly-owned subsidiary, MSDW Services, pursuant to an
Administration Agreement with MIOT, serves as the Administrator of MIOT and

   (2) RATIFICATION OR REJECTION OF SELECTION OF INDEPENDENT ACCOUNTANTS

   The Trustees/Directors of each Fund have unanimously selected the firm of
PricewaterhouseCoopers LLP as each Fund's independent accountants for the
fiscal years ending September 30, 1999 for DWGIT, HIAT and ICIS; for the
fiscal year ending July 31, 1999 for HIAT II; and for the fiscal year ending
May 31, 1999 for MIOT. Its selection is being submitted for ratification or
rejection by Shareholders of each Fund at the Meetings.
PricewaterhouseCoopers LLP has been the independent accountants for each Fund
since its inception, and has no direct or indirect financial interest in any
of the Funds.

   A representative of PricewaterhouseCoopers LLP is expected to be present
at the Meetings and will be available to respond to appropriate questions of
Shareholders.

   The affirmative vote of the holders of a majority of the shares
represented and entitled to vote at the Annual Meeting is required for
ratification of the selection of PricewaterhouseCoopers LLP as the
independent accountants for each respective Fund.

   THE TRUSTEES/DIRECTORS OF EACH FUND UNANIMOUSLY RECOMMEND THAT THE
SHAREHOLDERS RATIFY THE SELECTION OF PRICEWATERHOUSECOOPERS LLP AS THE
INDEPENDENT ACCOUNTANTS.

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

   The management of MSDW Advisors has recommended to the Board of Directors
of the Fund that the name of the Fund be changed to "Morgan Stanley Dean
Witter Income Securities Inc." in view of recent changes, including the
consummation of the merger of Dean Witter, Discover & Co. with Morgan Stanley
Group Inc. on May 31, 1997, the name change of the Investment Manager, Dean
Witter InterCapital Inc. to Morgan Stanley Dean Witter Advisors Inc. on June
22, 1998, and the recent and forthcoming name changes of most of the Morgan
Stanley Dean Witter Funds to include the brand name of "Morgan Stanley Dean
Witter." The Board of Directors and the Fund's management believe that
changing the Fund's name to "Morgan Stanley Dean Witter Income Securities
Inc." would reflect more accurately the association with MSDW Advisors and 
MSDW, the parent company of MSDW Advisors and that a continuation of the name 
InterCapital may lead to confusion with respect to the relationship between 
the Fund, the Investment Manager and other Morgan Stanley Dean Witter Funds. 

   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 Dean Witter 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 DEAN WITTER 
INCOME SECURITIES INC." 

                            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 for a total of not more 
than 60 days in the aggregate to 

                                       17

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. 

                            SHAREHOLDER PROPOSALS 

   Proposals of security holders intended to be presented at the next Annual
Meeting of Shareholders of each respective Fund must be received by no later
than July 9, 1999 for DWGIT, HIAT, HIAT II, ICIS and MIOT, for inclusion in the
proxy statement for each respective Fund's next Annual Meeting. The mere
submission of a proposal does not guarantee its inclusion in the proxy
materials or its presentation at the meeting. Certain rules under the federal
securities laws must be met.

                           REPORTS TO SHAREHOLDERS 

   EACH FUND'S MOST RECENT ANNUAL REPORT, AND IN THE CASE OF DWGIT, HIAT AND 
ICIS, THE MOST RECENT SEMI-ANNUAL REPORT SUCCEEDING THE ANNUAL REPORT, 
PREVIOUSLY HAVE BEEN SENT TO SHAREHOLDERS AND ARE AVAILABLE WITHOUT CHARGE 
UPON REQUEST FROM ADRIENNE RYAN-PINTO AT MORGAN STANLEY DEAN WITTER TRUST 
FSB, HARBORSIDE FINANCIAL CENTER, PLAZA TWO, JERSEY CITY, NEW JERSEY 07311 
(TELEPHONE 1-800-869-NEWS) (TOLL-FREE). 

                         INTEREST OF CERTAIN PERSONS 

   MSDW, MSDW Advisors, DWR, MSDW Services, and certain of their respective 
Directors, Officers, and employees, including persons who are 
Trustees/Directors or Officers of the Funds, may be deemed to have an 
interest in certain of the proposals described in this Proxy Statement to the 
extent that certain of such companies and their affiliates have contractual 
and other arrangements, described elsewhere in this Proxy Statement, pursuant 
to which they are paid fees by the Funds, and certain of those individuals 
are compensated for performing services relating to the Funds and may also 
own shares of MSDW. Such companies and persons may thus be deemed to derive 
benefits from the approvals by Shareholders of such proposals. 

                                OTHER BUSINESS 

   The management of the Funds knows of no other matters which may be 
presented at the Meetings. However, if any matters not now known properly 
come before the Meetings, it is the intention of the persons named in the 
enclosed form of proxy to vote all shares that they are entitled to vote on 
any such matter, utilizing such proxy in accordance with their best judgment 
on such matters. 
                                          By Order of the Boards of 
                                          Trustees/Directors
