                        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 , 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            shares of beneficial interest of DWGIT,
           shares of beneficial interest of HIAT,            shares of
beneficial interest of HIAT II,            shares of common stock of ICIS and
           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
<PAGE>

     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.

</TABLE>

     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 Board 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
<PAGE>

     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
parentheses), positions with the Funds, and directorships or trusteeships 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 $  .  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


                                       7
<PAGE>

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. 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.

     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 FOR ALL MORGAN
STANLEY DEAN WITTER FUNDS

     The Independent Trustees and the Funds' management believe that having the
same Independent Trustees 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 for each of the Funds or even of
sub-groups of Funds. They believe that having the same individuals serve as
Independent Trustees 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


                                       8
<PAGE>

also precludes the possibility of separate groups of Independent Trustees
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 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 of the caliber, experience and business acumen
of the individuals who serve as Independent Trustees of the Morgan Stanley Dean
Witter Funds.


SHARE OWNERSHIP BY TRUSTEES

     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 September 30,
1998, 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 $    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 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


                                       9
<PAGE>

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:

THE INVESTMENT MANAGER OR INVESTMENT ADVISER

     Morgan Stanley Dean Witter Advisors Inc. is each Fund's investment manager
or investment adviser. MSDW Advisors maintains its offices at Two World Trade
Center, New York, New York 10048. MSDW Advisors, which was incorporated in
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

businesses--securities, asset management and credit services.

     The Principal Executive Officer and Directors of MSDW Advisors are

and other Directors is Two World Trade Center, New York, New York 10048.

     MSDW has its offices at 1585 Broadway, New York, New York 10036. There are
various lawsuits pending against MSDW involving material amounts which, in the
opinion of its management, will be resolved with no material effect on 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
and individual investors. The Appendix lists the investment companies for which
MSDW Advisors provides investment management or investment advisory services
and which have similar investment objectives to those of the Funds listed in
this Proxy Statement and sets forth the fees payable to MSDW Advisors by such
companies, including the Funds, and their net assets as of October 28, 1998.

     MSDW Advisor's wholly-owned subsidiary, MSDW Services, pursuant to an
Administration Agreement with MIOT, serves as the Administrator of MIOT and
receives from the Fund compensation which is computed and accrued weekly and
payable monthly and which is determined by applying the annual rate of 0.30% to
the Fund's average weekly net assets. During the fiscal year ended May 31, 1998
for MIOT, the Fund accrued to MSDW Services administrative fees of $579,262.

     During the fiscal year ended September 30, 1998 for DWGIT, September 30,
1998 for HIAT, July 31, 1998 for HIAT II, September 30, 1998 for ICIS, and May

AFFILIATED BROKER

Incorporated.

     (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
<PAGE>

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, as set forth
in each Fund's previous proxy statement, by no later than July 7, 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
