Dear Van Kampen American Capital Fund Shareholder:
 
  The enclosed proxy statement relates to a joint meeting of the shareholders of
a number of Van Kampen American Capital funds. We are pleased to announce that
Morgan Stanley Group Inc., the indirect corporate parent of the investment
adviser of your Fund, has entered into a merger agreement with Dean Witter,
Discover & Co. Under the terms of the merger agreement, your Fund's investment
adviser will become an indirect subsidiary of the merged company, to be named
Morgan Stanley, Dean Witter, Discover & Co. Your Fund's investment adviser will
continue to provide the Fund with investment advisory and management services
following the merger.
 
  The primary purpose of the shareholder meeting is to permit the shareholders
of each Fund to consider a new investment advisory agreement to take effect
following the merger. The new investment advisory agreement between your Fund
and its investment adviser will be substantially similar to the Fund's current
investment advisory agreement, except for certain provisions added at the
request of your trustees. The attached proxy statement seeks shareholder
approval on this and other items.
 
                 Your vote is important and your participation
           in the governance of your Fund(s) does make a difference.
 
  The proposals have been unanimously approved by the Board of Trustees of each
Fund, who recommend you vote "FOR" each of these proposals. YOUR IMMEDIATE
RESPONSE WILL HELP SAVE ON THE COSTS OF ADDITIONAL SOLICITATIONS. EACH FUND
VOTES SEPARATELY, SO PLEASE SIGN AND RETURN ALL OF YOUR FUND PROXY FORMS. We
look forward to your participation, and we thank you for your continued
confidence in Van Kampen American Capital.

                                  MAY 28, 1997
 
  This Proxy Statement is furnished in connection with the solicitation by the
Boards of Trustees (the "Trustees" or "Board of Trustees") of each of the Van
Kampen American Capital Funds listed on Annex A to this Proxy Statement (the
"Funds") of proxies to be voted at a Joint Special Meeting of Shareholders of
the Funds, and all adjournments thereof (the "Meeting"), to be held at the
offices of Van Kampen American Capital, Inc., One Parkview Plaza, Oakbrook
Terrace, Illinois 60181, on Wednesday, May 28, 1997, at 11:00 a.m. The
approximate mailing date of this Proxy Statement and accompanying form of proxy
is April 21, 1997.
 
  The primary purpose of the Meeting is to permit each Fund's shareholders to
consider a New Advisory Agreement (defined below) to take effect following the
consummation of the transactions contemplated by an Agreement and Plan of
Merger, dated as of February 4, 1997 (the "Merger Agreement"), between Dean
Witter, Discover & Co. ("Dean Witter Discover") and Morgan Stanley Group Inc.
("Morgan Stanley"), the indirect parent corporation of each Fund's investment
adviser. Pursuant to the Merger Agreement, each Fund's investment adviser will
become an indirect subsidiary of the merged company, which will be called Morgan
Stanley, Dean Witter, Discover & Co. ("MSDWD").
 
  Participating in the Meeting are holders of common shares of beneficial
interest, par value $0.01 per share (collectively, the "Shares"), of each of the
Funds. The Meeting is scheduled as a joint meeting of the shareholders of the
Funds because the shareholders of the Funds are expected to consider and vote on
similar matters. The Board of Trustees has determined that the use of a joint
proxy statement for the Meeting is in the best interest of the shareholders of
the Funds. In the event that a shareholder of any Fund present at the Meeting
objects to the holding of a joint meeting and moves for an adjournment of the
meeting of such Fund to a time immediately after the Meeting so that such Fund's
meeting may be held separately, the persons named as proxies will vote in favor
of the adjournment.
 
  Annex A lists the abbreviated names by which the Funds sometimes are referred
to in this Proxy Statement. Please refer to Annex A for any questions you may
have regarding whether your Fund is participating at the Meeting, defined terms
relating to the Funds and abbreviated Fund names. Other Van Kampen American
Capital
<PAGE>   9
 
investment companies not listed on Annex A will vote at separate shareholder
meetings on proposals substantially similar to the proposals in this Proxy
Statement. They will hold separate shareholder meetings because they are
supervised by boards of trustees that are not identical to the Board of Trustees
of the Funds or their shareholders will consider proposals which do not affect
the Funds. If you are a shareholder of Van Kampen American Capital investment
companies not listed on Annex A, you will receive one or more additional proxy
statements relating to such other shareholder meetings.
 
  The following table summarizes each proposal to be presented at the Meeting
and the Funds solicited with respect to such proposal:

PLAZA, OAKBROOK TERRACE, ILLINOIS 60181.
 
VOTING
 
  The Board of Trustees has fixed the close of business on April 14, 1997, as
the record date (the "Record Date") for the determination of holders of Shares
of each Fund entitled to vote at the Meeting. Shareholders of a Fund on the
Record Date will be entitled to one vote per Share with respect to each proposal
submitted to the shareholders of the Fund, with no Share having cumulative
voting rights.
 
  The voting requirement for passage of a particular proposal depends on the
nature of the particular proposal. With respect to Proposals 1, 2, 4 and 5, the
voting requirement is the "vote of a majority of the outstanding voting
securities", which is defined under the 1940 Act, as the lesser of (i) 67% or
more of the voting securities of each respective Fund entitled to vote thereon
present in person or by proxy at the Meeting, if the holders of more than 50% of
the outstanding voting securities entitled to vote thereon are present in person
or represented by proxy or (ii) more than 50% of the outstanding voting
securities of each respective Fund entitled to vote thereon. With respect to
Proposal 3, the affirmative vote of a plurality of the Shares of a Fund present
in person or by proxy is necessary to elect each nominee to the Board of
Trustees of each Fund. With respect to Proposal 6, the affirmative vote of a
majority of the Shares of a Fund present in person or by proxy is necessary to
ratify the selection of the independent public accountants for such Fund.
 
  The Board of Trustees of each Fund recommends that you cast your vote:
 
  - FOR approval of each New Advisory Agreement;
 
  - FOR approval of each New Subadvisory Agreement;
 
  - FOR each nominee for the Board of Trustees;
 
  - FOR amendments to the fundamental investment policies of High Income
    Corporate Bond Fund;
 
  - FOR an amendment to the fundamental investment policies of the Harbor Fund;
    and
 
  - FOR ratification of the independent public accountants for the current
    fiscal year of each Fund.
 
  All Shares of a Fund affected by a proposal will vote together as a single
class on such proposal. An unfavorable vote on a proposal by the shareholders of
one Fund will not affect the implementation of such a proposal by another Fund,
if the proposal is approved by the shareholders of the other Fund. There is no
cumulative voting with respect to the election of Trustees.
 
                                        3

  All properly executed proxies received prior to the Meeting will be voted at
the Meeting in accordance with the instructions marked thereon. Proxies received
prior to the Meeting on which no vote is indicated will be voted "for" each
proposal as to which it is entitled to vote. Abstentions do not constitute votes
"for" a proposal and are treated as votes "against" a proposal. Broker non-votes
(i.e., proxies from brokers or nominees indicating that such persons have not
received instructions from the beneficial owner or other person entitled to vote
shares on a particular matter with respect to which the broker or nominees do
not have discretionary power) do not constitute votes "for" or "against" a
proposal and are disregarded in determining the "votes cast" when the voting
requirement for a proposal is based on achieving a percentage of the voting
securities entitled to vote present in person or by proxy at the meeting. Broker
non-votes do not constitute votes "for" and are treated as votes "against" when
the voting requirement for a proposal is based on achieving a percentage of the
outstanding voting securities entitled to vote. A majority of the outstanding
Shares entitled to vote on a proposal must be present in person or by proxy to
have a quorum to conduct business at the Meeting. Abstentions and broker
non-votes will be deemed present for quorum purposes.
 
  Shareholders who execute proxies may revoke them at any time before they are
voted by filing with the respective Fund a written notice of revocation, by
delivering a duly executed proxy bearing a later date or by attending the
Meeting and voting in person.
 
  The Funds know of no business other than that mentioned in Proposals 1 through
6 of the Notice that will be presented for consideration at the Meeting. If any
other matters are properly presented, it is the intention of the persons named
on the enclosed proxy to vote proxies in accordance with their best judgment. In
the event a quorum is present at the Meeting but sufficient votes to approve any
of the proposals with respect to one or more Funds or proposals are not
received, the persons named as proxies may propose one or more adjournments of
the Meeting of the concerned Fund or proposal to permit further solicitation of
proxies, provided they determine that such an adjournment and additional
solicitation is reasonable and in the interest of shareholders based on a
consideration of all relevant factors, including the nature of the relevant
proposal, the percentage of votes then cast, the percentage of negative votes
then cast, the nature of the proposed solicitation activities and the nature of
the reasons for such further solicitation. An unfavorable vote on a proposal by
the shareholders of a Fund will not affect such Fund's implementation of those
proposals that receive a favorable vote.

THE MERGER
 
  Pursuant to the Merger Agreement, Morgan Stanley will be merged (the "Merger")
with and into Dean Witter Discover and the surviving corporation will be named
Morgan Stanley, Dean Witter, Discover & Co. ("MSDWD"). Following the Merger, the
Adviser will be an indirect subsidiary of MSDWD.
 
  Under the terms of the Merger Agreement, each of Morgan Stanley's common
shares will be converted into the right to receive 1.65 shares of MSDWD common
stock and each issued and outstanding share of Dean Witter Discover common stock
will thereafter represent one share of MSDWD common stock. Following the Merger,
Morgan Stanley's former shareholders will own approximately 45% and Dean Witter
Discover's former shareholders will own approximately 55% of the outstanding
shares of common stock of MSDWD.
 
  The Merger is expected to be consummated in mid-1997 and is subject to certain
closing conditions, including certain regulatory approvals and the approval of
shareholders of both Morgan Stanley and Dean Witter Discover.
 
  Under the terms of the Merger Agreement, the Board of Directors of MSDWD
initially will consist of fourteen members, two of whom will be Morgan Stanley
insiders and two of whom will be Dean Witter Discover insiders. The remaining
ten directors will be independent directors, with Morgan Stanley and Dean Witter
Discover each nominating five of the ten. The Chairman and Chief Executive
Officer of MSDWD will be the current Chairman and Chief Executive Officer of
Dean Witter Discover, Phillip Purcell. The President and Chief Operating Officer
of MSDWD will be the current President of Morgan Stanley, John Mack.
 
  The Adviser does not anticipate any reduction in the quality of services now
provided to the Funds, and do not expect that the Merger will result in any
material changes in the business of the Adviser or in the manner in which the
Adviser renders services to the Funds. The Adviser also anticipates that neither
the Merger nor any ancillary transactions will have any adverse effect on the
Adviser's ability to fulfill its obligations under the New Advisory Agreements
(as defined below) or to operate its business in a manner consistent with past
business practices.
 
  In connection with Morgan Stanley's purchase of VKAC Holding on October 31,
1996, certain officers of the Adviser, including Dennis J. McDonnell, who is a
member of the Board of Trustees, and Don G. Powell, who was a member of the
Board of Trustees prior to August 1996, entered into employment agreements with
VKAC Holding which expire from between 1998 and 2000. Certain of such officers,
including Messrs. McDonnell and Powell also were granted options to purchase
shares of common stock of Morgan Stanley which vest from 1999 to 2001. Certain
officers of the Adviser also entered into retention agreements with VKAC
Holding, which will remain in place following the consummation of the Merger.
The employment agreements and retention agreements are intended to assure that
the
 
                                        6
<PAGE>   14
 
services of the officers are available to the Adviser (and thus to the Funds)
until such agreements expire. Finally, certain officers of the Adviser,
including Messrs. McDonnell and Powell, received preferred stock of Morgan
Stanley that is convertible into common stock of Morgan Stanley from 1997 to
2000. As a result of the Merger, such preferred stock shall be convertible into
common stock of MSDWD at the effective time of the Merger.
 
THE ADVISORY AGREEMENTS
 
  In anticipation of the Merger, a majority of the Trustees of each Fund who are
not parties to the New Advisory Agreement or interested persons of any such
party ("Disinterested Trustees") approved a new investment advisory agreement
(the "New Advisory Agreement") between each Fund and the Adviser. The holders of
a majority of the outstanding voting securities (within the meaning of the 1940
Act) of each Fund are being asked to approve its respective New Advisory
Agreement. See "The New Advisory Agreements" below.
 
  THE CURRENT ADVISORY AGREEMENTS. The Current Advisory Agreement for each Fund
was last approved by a majority of the Trustees, including a majority of the
Disinterested Trustees, voting in person at a meeting called for that purpose on
July 25, 1996 in connection with the acquisition of Asset Management's corporate
parent by Morgan Stanley. The Current Advisory Agreement was last approved by
shareholders of each Fund at a meeting held on October 25, 1996 relating to the
acquisition of Asset Management's corporate parent by Morgan Stanley.
 
  Each Current Advisory Agreement provides that the Adviser will supply
investment research and portfolio management, including the selection of
securities for each Fund to purchase, hold or sell and the selection of brokers
through whom that Fund's portfolio transactions are executed. The Adviser also
administers the business affairs of each Fund, furnishes offices, necessary
facilities and equipment, provides administrative services, and permits its
officers and employees to serve without compensation as Trustees and officers of
such Fund if duly elected to such positions.
 
  Each Current Advisory Agreement provides that the Adviser shall not be liable
for any error of judgment or of law, or for any loss suffered by the particular
Fund in connection with the matters to which the Current Advisory Agreement
relates, except in the case of a loss resulting from willful misfeasance, bad
faith, negligence or reckless disregard of obligations or duties on the part of
Asset Management in the performance of its obligations and duties under each
Current Advisory Agreement.
 
  [The fees payable to Asset Management by each Fund are reduced by any
commissions, tender solicitation and other fees, brokerage or similar payments
received by Asset Management or any other direct or indirect majority-owned
 
                                        7
<PAGE>   15
 
subsidiary of Morgan Stanley in connection with the purchase or sale of
portfolio investments of such Fund, less expenses incurred by Asset Management
in connection with such activities.]
 
  The Adviser's activities are subject to the review and supervision of the
Board of Trustees, to which the Adviser renders periodic reports with respect to
each Fund's investment activities. The Current Advisory Agreement may be
terminated by either party, at any time, without penalty, upon 60 days written
notice, and automatically terminates in the event of its assignment. The Current
Advisory Agreement also terminates if either a Fund or Asset Management goes
into liquidation or a receiver is appointed with respect to their assets or if
either party breaches the Current Advisory Agreement and fails to remedy the
breach within 30 days of receiving notice thereof from the other party.
 
  The net assets of each of the Funds as of March 31, 1997, as well as other
investment companies sponsored by VKAC and advised by the Adviser, and the rates
of compensation to the Adviser are set forth at Annex C hereto. Each respective
Fund recognized net advisory expenses, for its most recently completed fiscal
year, in the amounts set forth at Annex D hereto.
 
  Each Fund pays all other expenses incurred in its operation including, but not
limited to, direct charges relating to the purchase and sale of its portfolio
securities, interest charges, fees and expenses of outside legal counsel and
independent auditors, taxes and governmental fees, costs of share certificates
and any other expenses (including clerical expenses) of issuance, sale or
repurchase of its Shares, expenses in connection with its dividend reinvestment
plan, membership fees in trade associations, expenses of registering and
qualifying its Shares for sale under federal and state securities laws, expenses
of printing and distribution, expenses of filing reports and other documents
filed with governmental agencies, expenses of annual and special meetings of the
trustees and shareholders, fees and disbursements of the transfer agents,
custodians and sub-custodians, expenses of disbursing dividends and
distributions, fees, expenses and out-of-pocket costs of the trustees who are
not affiliated with the Adviser, insurance premiums, indemnification and other
expenses not expressly provided for in each Current Advisory Agreement, and any
extraordinary expenses of a nonrecurring nature. Each Fund also compensates its
Adviser, VKAC, the Distributor (defined below) and ACCESS (defined below) for
certain non-advisory services provided pursuant to agreements discussed below.
See "OTHER INFORMATION -- Non-Advisory Agreements" below.
 
  THE NEW ADVISORY AGREEMENTS. The Board of Trustees approved a proposed New
Advisory Agreement between each Fund and Asset Management on March 27, 1997, the
form of which is attached hereto as Annex B-1. The form of the proposed New
Advisory Agreement between each Fund and the Adviser is substantially similar to
the Current Advisory Agreement. The material differences between the Current
Advisory Agreement and the New Advisory Agreement are described in
 
                                        8
<PAGE>   16
 
this paragraph. Each New Advisory Agreement designates certain officers of the
Adviser and the officers of each Fund as essential personnel with respect to the
operations of the respective Fund. Under the terms of the New Advisory
Agreement, the Adviser may not make any material or significant personnel
changes or replace any essential personnel or materially change the
responsibilities or duties of any essential personnel prior to the first
anniversary of the agreement without first informing the Board of Trustees in a
timely manner. Each New Advisory Agreement also prohibits the Adviser from
changing its name without the prior consent of the Board of Trustees.
 
  The investment advisory fee as a percentage of net assets payable by each Fund
will be the same under each New Advisory Agreement as under the Current Advisory
Agreement. If the investment advisory fee under each New Advisory Agreement had
been in effect for each Fund's most recently completed fiscal year, contractual
advisory fees payable to the Adviser by each Fund would have been identical to
those payable under each Current Advisory Agreement.
 
  In connection with approving the New Advisory Agreements, the Boards of
Trustees held a special telephone meeting on February 10, 1997 and held special
in-person meetings on March 14, 1997 and March 27, 1997. At the meetings, the
Boards of Trustees considered the possible effects of the Merger upon VKAC, the
Adviser, Van Kampen American Capital Distributors, Inc., the distributor of the
Funds' shares (the "Distributor"), and ACCESS Investors Services, Inc., the
transfer agent for each of the Funds ("ACCESS"), and upon their ability to
provide investment advisory, distribution, transfer agency and other services to
each respective Fund. Representatives of Morgan Stanley, Dean Witter Discover
and VKAC attended one or more of the in-person meetings and represented to the
Boards of Trustees that (i) the VKAC family of funds will be maintained and
operated as a separate mutual fund complex and will not be consolidated with
Dean Witter Discover's InterCapital Funds, and (ii) VKAC, the Adviser, the
Distributor and ACCESS will be maintained separate from their counterparts in
the InterCapital Fund complex and will be operated for the benefit of the Funds
and other investment companies sponsored by VKAC. The representatives of Morgan
Stanley, Dean Witter Discover and VKAC also stated that (i) the Funds will
continue to be distributed by the Distributor through third-party broker-dealers
and, following the Merger, also will be distributed through Dean Witter
Discover's broker-dealers on a proprietary basis, and (ii) the InterCapital
Funds will continue to be distributed solely through Dean Witter Discover
broker-dealers on a proprietary basis. The representatives of Morgan Stanley and
Dean Witter Discover also described the financial and other resources available
to VKAC and its affiliates, after giving effect to the Merger, to secure for
each Fund quality investment research, investment advice, distribution, transfer
agency and other client services.
 
  In evaluating the New Advisory Agreements, the Boards of Trustees took into
account that each Fund's Current Advisory Agreement and its New Advisory
 
                                        9
<PAGE>   17
 
Agreement, including the terms relating to the services to be provided
thereunder by the Adviser and the fees and expenses payable by each Fund, are
substantially similar, except for those provisions added to each New Advisory
Agreement at the request of the Trustees (see The Advisory Agreements -- The New
Advisory Agreements above). The Boards of Trustees considered the skills and
capabilities of the Adviser, the representations of Morgan Stanley, Dean Witter
Discover and VKAC described above and the representations of officers of Morgan
Stanley and Dean Witter Discover that no material change was planned in the
current management or facilities of the Adviser. The Boards of Trustees also
considered the reputation, expertise and resources of Morgan Stanley and Dean
Witter Discover and their affiliates in domestic and international financial
markets. The Boards of Trustees considered the continued employment of members
of senior management of the Adviser, the Distributor and ACCESS pursuant to
current and future employment and retention agreements to be important to help
assure the continuity of the personnel primarily responsible for maintaining the
quality of investment advisory and other services for the Funds. The Board of
Trustees also considered the affect of certain shares of preferred stock of
Morgan Stanley owned by senior management of the Adviser becoming immediately
convertible into common stock of Morgan Stanley at the time of the Merger. The
Trustees considered the possible benefits the Adviser may receive as a result of
the Merger, including the continued use, to the extent permitted by law, of
Morgan Stanley & Co., DWR and their affiliates for brokerage services.
 
  The Boards of Trustees considered the affects on the Funds of the Adviser
becoming an affiliated person of MSDWD. Following the Merger, the 1940 Act will
prohibit or impose certain conditions on the ability of the Funds to engage in
certain transactions with MSDWD and its affiliates. For example, absent
exemptive relief, the Funds will be prohibited from purchasing securities from
Morgan Stanley & Co. or DWR, both of which will be wholly-owned broker-dealer
subsidiaries of MSDWD, in transactions in which Morgan Stanley & Co. or DWR acts
as a principal, and the Funds will have to satisfy certain conditions in order
to engage in securities transactions in which Morgan Stanley & Co. or DWR act as
a broker or to purchase securities in an underwritten offering in which Morgan
Stanley & Co. or DWR is acting as an underwriter. In this connection, management
of the Adviser represented to the Boards of Trustees that they do not believe
these prohibitions or conditions will have a material affect on the management
or performance of the Funds and, to the extent permitted by applicable law, VKAC
anticipates that the Funds will continue to use Morgan Stanley & Co., DWR and
their affiliates for brokerage services.
 
  The Boards of Trustees were advised that Section 15(f) of the 1940 Act is
still applicable to the Adviser as a result of Morgan Stanley's previous
acquisition of the Adviser's parent corporation on October 31, 1996. Section
15(f) of the 1940 Act permits, in the context of a change in control of an
investment adviser to a registered investment company, the receipt by such
investment adviser, or any of its
 
                                       10
<PAGE>   18
 
affiliated persons, of an amount of benefit in connection with such sale,
provided two conditions are satisfied. First, an "unfair burden" must not be
imposed on the investment company for which the investment adviser acts in such
capacity as a result of the sale of such interest, or any express or implied
terms, conditions or understandings applicable thereto. The term "unfair
burden," as defined in the 1940 Act, includes any arrangement during the
two-year period after the transaction whereby the investment adviser (or
predecessor or successor adviser), or any interested person of any such adviser,
receives or is entitled to receive any compensation, directly or indirectly,
from the investment company or its security holders (other than fees for bona
fide investment advisory and other services), or from any person in connection
with the purchase or sale of securities or other property to, from or on behalf
of the investment company (other than ordinary fees for bona fide principal
underwriting services). Management of Morgan Stanley, Dean Witter Discover and
VKAC are aware of no circumstances arising from the Merger, preparatory
transactions to the Merger or any potential financing that might result in the
imposition of an "unfair burden" on the Funds.
 
  The second condition of Section 15(f) is that during the three-year period
immediately following a transaction to which Section 15(f) is applicable, at
least 75% of the subject investment company's board of directors must not be
"interested persons" (as defined in the 1940 Act) of the investment company's
investment adviser or predecessor adviser. The composition of the Boards of
Trustees currently complies with such condition and, if each of the nominees set
forth in Proposal 3 below is elected to the Boards of Trustees, the composition
of the Boards of Trustees would comply with such condition.
 
  The Boards of Trustees, including the Disinterested Trustees, concluded that
if the Merger occurs, entry by each respective Fund into a New Advisory
Agreement would be in the best interest of each Fund and the shareholders of
each Fund. The Boards of Trustees of each Fund, including the Disinterested
Trustees, unanimously approved the New Advisory Agreement for each Fund and
recommended each such agreement for approval by the shareholders of the
respective Fund at the Meeting. The New Advisory Agreement would take effect
upon the later to occur of (i) the obtaining of shareholder approval or (ii) the
closing of the Merger. Each New Advisory Agreement will continue in effect until
May 31, 1999 and thereafter for successive annual periods as long as such
continuance is approved in accordance with the 1940 Act.
 
  In the event that shareholders of a Fund do not approve the New Advisory
Agreement with respect to a Fund and the Merger is consummated, the Board of
Trustees of such Fund would seek to obtain for the Fund interim investment
advisory services at the lesser of cost or the current fee rate either from the
respective Adviser or from another advisory organization. Thereafter, the Board
of Trustees of such Fund would either negotiate a new investment advisory
agreement
 
                                       11
<PAGE>   19
 
with an advisory organization selected by the Board of Trustees or make other
appropriate arrangements, in either event subject to approval of the
shareholders of such Fund. In the event the Merger is not consummated, the
Advisers would continue to serve as investment adviser of the Funds pursuant to
the terms of the Current Advisory Agreement.
 
SHAREHOLDER APPROVAL
 
  To become effective, each New Advisory Agreement must be approved by the vote
of a majority of the outstanding voting securities of the respective Fund. The
"vote of a majority of the outstanding voting securities" is defined under the
1940 Act as the lesser of (i) 67% or more of the Shares of the respective Fund
entitled to vote thereon present in person or by proxy at the Meeting if the
holders of more than 50% of such outstanding Shares are present in person or
represented by proxy; or (ii) more than 50% of such outstanding Shares of the
respective Fund entitled to vote thereon. Each New Advisory Agreement was
unanimously approved by the Board of Trustees after consideration of all factors
which they determined to be relevant to their deliberations, including those
discussed above. The Board of Trustees also unanimously determined to submit
each New Advisory Agreement for consideration by the shareholders of the
respective Fund. THE BOARD OF TRUSTEES OF EACH FUND RECOMMENDS A VOTE "FOR"
APPROVAL OF THE NEW ADVISORY AGREEMENT.

  Under the Current MSAM Subadvisory Agreements, Asset Management retains MSAM
to assist Asset Management with providing advisory services to the Global Funds,
including services regarding investments in securities and the selection of
broker-dealers. In this connection, the Current MSAM Subadvisory Agreements
provide that MSAM provides Asset Management and each Global Fund (i) investment
advice with respect to all or such portion of each Global Fund's assets as
determined from time to time by Asset Management and MSAM;
 
                                       13
<PAGE>   21
 
(ii) economic, statistical and research information and advice, including advice
on the allocation of investments among countries, relating to all or such
portion of each Global Fund's assets as MSAM and Asset Management shall from
time to time determine; (iii) recommendations as to the voting of proxies
solicited by or with respect to securities under MSAM's supervision; and (iv) an
investment program with respect to securities and recommendations as to what
securities shall be purchased, sold or exchanged, and in what portion, if any,
of the securities shall be held in money market instruments. MSAM determines the
securities to be purchased and sold by each Global Fund, places orders for the
purchase, sale and exchange of securities with broker-dealers and gives
instructions to each Global Fund's custodian and sub-custodians in connection
with such transactions.
 
  The Current MSAM Subadvisory Agreements provide that MSAM shall not be liable
to the Global Funds or any shareholders thereof for any error of judgment or of
law, or for any loss suffered by the Global Funds in connection with the matters
in which the Current MSAM Subadvisory Agreement relates, except in the case of a
loss resulting from willful misfeasance, bad faith, negligence or reckless
disregard of its obligations or duties.
 
  The Current MSAM Subadvisory Agreement terminates automatically on its
assignment and on the termination of the advisory agreement between Asset
Management and the respective Global Fund and may be terminated at any time,
without the payment of any penalty, by (i) the Board of Trustees, (ii) a "vote
of a majority of the outstanding voting securities" (as defined in the 1940 Act)
of the respective Global Fund, or (iii) by Asset Management or MSAM, as the case
may be, in each case on 30 days' written notice, or upon such shorter notice as
may be mutually agreed upon.
 
  The rate of compensation to MSAM under the Current MSAM Subadvisory Agreement
for each Global Securities Fund is equal to [50%] of the net advisory fees
received by Asset Management under the respective Current Advisory Agreement.
During each Global Fund's most recently completed fiscal year, MSAM received no
subadvisory fees from Asset Management because MSAM did not act as subadviser to
the Global Funds during such fiscal years. The net assets of the Global Funds as
of March 31, 1997, are included as part of Annex [ ] hereto.
 
THE NEW MSAM SUBADVISORY AGREEMENT
 
  The Boards of Trustees of the Global Funds approved the proposed new MSAM
subadvisory agreement for each Global Fund between Asset Management and MSAM on
March 27, 1997 (the "New MSAM Subadvisory Agreement"). The form of the proposed
New MSAM Subadvisory Agreement is substantially identical to the Current MSAM
Subadvisory Agreement, except for the dates of execution, effectiveness and
termination and except for certain provisions relating to each Global Fund's
previous subadviser that have expired by their terms. The
 
                                       14
<PAGE>   22
 
investment subadvisory fee payable by Asset Management to MSAM will be the
same under each New MSAM Subadvisory Agreement as under each Current MSAM
Subadvisory Agreement. The form of the New MSAM Subadvisory Agreement is
attached to this Proxy Statement as Annex B-2 (the "New MSAM Subadvisory
Agreement").
 
  Each New MSAM Subadvisory Agreement will take effect upon the later to occur
of (i) the obtaining of shareholder approval or (ii) the closing of the Merger.
Each New MSAM Subadvisory agreement will continue in effect until May 31, 1999
and thereafter for successive annual periods as long as such continuance is
approved in accordance with the 1940 Act.
 
DELIBERATIONS OF THE BOARDS OF TRUSTEES
 
  The Boards of Trustees of the Global Funds held joint meetings in connection
with their consideration of the Merger as described above in Proposal 1, at
which meetings the Trustees, including the Disinterested Trustees, concluded
that if the Merger occurs, entry by each respective Global Fund into a New MSAM
Subadvisory Agreement would be in the best interest of each Global Fund and the
shareholders of each Global Fund. In evaluating the New MSAM Subadvisory
Agreements, the Boards of Trustees took into account that the Current MSAM
Subadvisory Agreements and the New MSAM Subadvisory Agreements, including the
terms relating to the services to be provided thereunder by MSAM and the fees
and expenses payable to MSAM by Asset Management, would be substantially
identical, except for the dates of execution, effectiveness and termination and
except for certain provisions relating to each Global Fund's previous subadviser
that have expired by their terms. The Boards of Trustees also took into
consideration those factors discussed above in Proposal 1 with respect to the
Merger and the representation of VKAC that it believes the Merger will not
adversely affect the operations, resources or finances of MSAM.
 
  Based upon their review, the Boards of Trustees concluded that the New MSAM
Subadvisory Agreement is in the best interest of each Global Fund and such
Global Fund's shareholders. Accordingly, after consideration of the above
factors, and such other factors and information that it deemed relevant, the
Board of Trustees of each Global Fund, including the Disinterested Trustees,
unanimously approved the New MSAM Subadvisory Agreement for each Global Fund and
recommended each such agreement for approval by the shareholders of the
respective Global Fund at the Meeting.
 
  In the event that shareholders of a Fund do not approve the New MSAM
Subadvisory Agreement with respect to a Fund and the Merger is consummated, the
Board of Trustees of such Fund would seek to obtain for the Fund interim
investment subadvisory services at the lesser of cost or the current fee rate
either from MSAM or from another advisory organization. Thereafter, the Board of
 
                                       15
<PAGE>   23
 
Trustees of such Fund would either negotiate a new investment subadvisory
agreement with an advisory organization selected by the Board of Trustees or
make other appropriate arrangements, in either event subject to approval of the
shareholders of such Fund. In the event the Merger is not consummated, MSAM
would continue to serve as subadviser to each of the Global Funds pursuant to
the terms of the Current MSAM Subadvisory Agreement.
 
SHAREHOLDER APPROVAL
 
  To become effective, each New MSAM Subadvisory Agreement must be approved by
the vote of a majority of the outstanding voting securities of the respective
Global Fund. The "vote of a majority of the outstanding voting securities" is
defined under the 1940 Act as the lesser of the vote of (i) 67% or more of the
Shares of the respective Global Fund entitled to vote thereon present at the
Meeting if the holders of more than 50% of such outstanding Shares are present
in person or represented by proxy; or (ii) more than 50% of such outstanding
Shares of the respective Global Fund entitled to vote thereon. Each New MSAM
Subadvisory Agreement was approved by the Board of Trustees after consideration
of all factors which they determined to be relevant to their deliberations,
including those discussed above. The Board of Trustees also unanimously
determined to submit each New MSAM Subadvisory Agreement for consideration by
the shareholders of the respective Global Fund. THE BOARD OF TRUSTEES OF EACH
GLOBAL FUND RECOMMENDS A VOTE "FOR" APPROVAL OF THE NEW MSAM SUBADVISORY
AGREEMENTS.
 
PROPOSAL 2B: APPROVAL OF NEW SUBADVISORY AGREEMENT WITH VAN KAMPEN AMERICAN
             CAPITAL ADVISORS, INC.
 
  Asset Management has entered into a subadvisory agreement with Van Kampen
American Capital Advisors, Inc. ("Advisors Inc.") in connection with providing
investment advisory services to the High Yield Municipal Fund (the "Current High
Yield Municipal Subadvisory Agreement"). Advisors Inc. has acted as subadviser
for the High Yield Municipal Fund since September 14, 1993.
 
ADVISORS INC.
 
  Advisors Inc. currently is a wholly-owned subsidiary of VKAC and an affiliate
of the Adviser. A description of those persons owning or controlling VKAC is set
forth above in the section of Proposal 1 captioned "The Adviser." The executive
officers of Advisors Inc., together with their principal occupations, are listed

address of Advisors Inc. is 40 Broad Street, Suite 828, Boston, MA 02110.
 
THE CURRENT HIGH YIELD MUNICIPAL SUBADVISORY AGREEMENTS
 
  The Board of Trustees of the High Yield Municipal Fund, including the
Independent Trustees, last approved the Current High Yield Municipal
 
                                       16
<PAGE>   24
 
Subadvisory Agreement on August 15, 1996. The shareholders of the High Yield
Municipal Fund last approved the Current High Yield Municipal Subadvisory
Agreement at a meeting held on October 25, 1996 relating to the acquisition of
Advisors Inc.'s corporate parent by Morgan Stanley.
 
  Under the Current High Yield Municipal Subadvisory Agreement, Asset Management
retains Advisors Inc. to assist Asset Management with providing investment
subadvisory services to the High Yield Municipal Fund, including (i) obtaining
and evaluating pertinent information about significant developments and
economic, statistical and financial data, with respect to the economy in
general, sectors of the municipal securities market, individual issuers and
securities in which the High Yield Municipal Fund invests, (ii) selecting
municipal securities and reporting on them to Asset Management and (iii)
formulating and implementing a continuous program for the purchase and sale of
securities and reporting thereon to Asset Management.
 
  The Current High Yield Municipal Subadvisory Agreement provides that Advisors
Inc. shall not be liable to the High Yield Municipal Fund or any shareholders
thereof for any error of judgement or of law, or for any loss suffered by the
High Yield Municipal Fund in connection with the matters in which the Current
High Yield Municipal Subadvisory Agreement relates, except in the case of a loss
resulting from willful misfeasance, bad faith, negligence or reckless disregard
of its obligations or duties.
 
  The Current High Yield Municipal Subadvisory Agreement terminates
automatically on its assignment and on the termination of the advisory agreement
between Asset Management and the High Yield Municipal Fund and may be terminated
at any time, without the payment of any penalty, by (i) the Board of Trustees,
(ii) a "vote of a majority of the outstanding voting securities" (as defined in
the 1940 Act) of the High Yield Municipal Fund, or (iii) by Asset Management or
Advisors Inc., as the case may be, in each case on 30 days' written notice, or
upon such shorter notice as may be mutually agreed upon.
 
  The rate of compensation to Advisors Inc. under the Current High Yield
Municipal Subadvisory Agreement is equal to 50% of the net advisory fees
received by Asset Management under its advisory agreement with the High Yield
Municipal Fund. During the High Yield Municipal Fund's most recently completed
fiscal year, Advisors Inc. received subadvisory fees from Asset Management in
the amount of $[         ]. The net assets of the High Yield Municipal Fund as
of March 31, 1997, are set forth on Annex C hereto. The High Yield Municipal
Fund is the only investment company advised or subadvised by Advisors Inc.
 
THE NEW HIGH YIELD MUNICIPAL SUBADVISORY AGREEMENT
 
  The Board of Trustees of the High Yield Municipal Fund approved the proposed
New High Yield Municipal Subadvisory Agreement between Asset Management and
Advisors Inc. on March 27, 1997. The form of the proposed New High Yield
 
                                       17
<PAGE>   25
 
Municipal Subadvisory Agreement is substantially identical to the Current High
Yield Municipal Subadvisory Agreement, except for the dates of execution,
effectiveness and termination. The form of the New High Yield Municipal
Subadvisory Agreement is attached to this Proxy Statement as Annex B-3.
 
  The investment subadvisory fee payable by Asset Management to Advisors Inc.
will be the same under the New High Yield Municipal Subadvisory Agreement as
under the Current High Yield Municipal Subadvisory Agreement. If the investment
subadvisory fee under the New High Yield Municipal Subadvisory Agreement had
been in effect for the High Yield Municipal Fund's most recently completed
fiscal year, subadvisory fees paid to Advisors Inc. by Asset Management would
have been identical to those paid under the Current High Yield Municipal
Subadvisory Agreement.
 
  The New High Yield Municipal Subadvisory Agreement would take effect upon the
later to occur of (i) the obtaining of shareholder approval or (ii) the closing
of the Merger. The New High Yield Municipal Subadvisory Agreement will continue
in effect until May 31, 1999 and thereafter for successive annual periods as
long as such continuance is approved in accordance with the 1940 Act.
 
DELIBERATIONS OF THE BOARD OF TRUSTEES
 
  The Board of Trustees of the High Yield Municipal Fund held meetings in
connection with their consideration of the Merger as described above in Proposal
1, at which meetings the Trustees, including the Disinterested Trustees,
concluded that if the Merger occurs, entry by the High Yield Municipal Fund into
the New High Yield Municipal Subadvisory Agreement would be in such Fund's best
interest and the best interest of its shareholders. In evaluating the New High
Yield Municipal Subadvisory Agreement, the Board of Trustees took into account
that the Current High Yield Municipal Subadvisory Agreement and the New High
Yield Municipal Subadvisory Agreement, including the terms relating to the
services to be provided thereunder by Advisors Inc. and the fees and expenses
payable to Advisors Inc. by Asset Management, would be substantially identical,
except for the dates of execution, effectiveness and termination. The Board of
Trustees also took into consideration those factors discussed above in Proposal
1 with respect to the Merger and the representation of VKAC that the Merger will
not adversely affect the operations, resources or finances of MSAM.
 
  Based upon its review, the Board of Trustees concluded that the New High Yield
Municipal Subadvisory Agreement is in the best interest of the High Yield
Municipal Fund. Accordingly, after consideration of the above factors, and such
other factors and information that it deemed relevant, the Board of Trustees of
the High Yield Municipal Fund, including the Disinterested Trustees, unanimously
approved the New High Yield Municipal Subadvisory Agreement and recom-
 
                                       18
<PAGE>   26
 
mended such agreement for approval by the shareholders of the High Yield
Municipal Fund at the Meeting.
 
  In the event that shareholders of the High Yield Municipal Fund do not approve
the New High Yield Municipal Subadvisory Agreement and the Merger is
consummated, the Board of Trustees of the High Yield Municipal Fund would seek
to obtain interim investment subadvisory services at the lesser of cost or the
current fee rate either from Advisors Inc. or from another advisory
organization. Thereafter, the Board of Trustees would either negotiate a new
investment subadvisory agreement with an advisory organization selected by the
Board of Trustees or make other appropriate arrangements, in either event
subject to approval of the shareholders of the High Yield Municipal Fund. In the
event the Merger is not consummated, Advisors Inc. would continue to serve as
subadviser to the High Yield Municipal Fund pursuant to the terms of the Current
High Yield Municipal Subadvisory Agreement.
 
SHAREHOLDER APPROVAL
 
  To become effective, the New High Yield Municipal Subadvisory Agreement must
be approved by the vote of a majority of the outstanding voting securities of
the High Yield Municipal Fund. The "vote of a majority of the outstanding voting
securities" is defined under the 1940 Act as the lesser of the vote of (i) 67%
or more of the Shares entitled to vote thereon present at the Meeting if the
holders of more than 50% of such outstanding Shares are present in person or
represented by proxy; or (ii) more than 50% of such outstanding Shares entitled
to vote thereon. The New High Yield Municipal Subadvisory Agreement was
unanimously approved by the Board of Trustees after consideration of all factors
which they determined to be relevant to their deliberations, including those
discussed above. The Board of Trustees also unanimously determined to submit the
New High Yield Municipal Subadvisory Agreement for consideration by the
shareholders of the High Yield Municipal Fund. THE BOARD OF TRUSTEES OF THE HIGH
YIELD MUNICIPAL FUND RECOMMENDS A VOTE "FOR" APPROVAL OF THE NEW HIGH YIELD
MUNICIPAL SUBADVISORY AGREEMENT.
- ------------------------------------------------------------------------------
PROPOSAL 3: ELECTION OF TRUSTEES
- ------------------------------------------------------------------------------
 
  Each Fund is organized as a series of a Delaware business trust (collectively,
the "Trusts"). With respect to each Trust, [    ] trustees are to be elected at
the Meeting to serve until reaching their designated retirement age or until
their successors are duly elected and qualified. The election of each nominee to
the Board of Trustees of a Trust requires the affirmative vote of a plurality of
all the Shares of such Trust present in person or by proxy. The shareholders of
all of the series of a Trust will vote together as a single class to elect the
trustees of the respective Trust. Those Trusts comprised of more than one series
are indicated as
 
                                       19
<PAGE>   27
 
such on Annex A hereto. It is the intention of the persons named in the enclosed
proxy to vote the Shares represented by them for the election of each nominee
listed below unless the proxy is marked otherwise.
 
THE TRUSTEES
 
  Each of the nominees to the Board of Trustees listed below has served as a
member of the Board of Trustees since his or her initial election or appointment
to the Board of Trustees as set forth in Annex J, except that Mr. Richard M.
DeMartini has not previously served on the Board of Trustees. The Board of
Trustees has determined that adding Mr. DeMartini to the Board of Trustees is in
the best interest of shareholders of each respective Fund following the Merger.
The Board of Trustees believes that adding Mr. DeMartini to the Board of
Trustees will benefit the Funds because of his knowledge of, and experience
with, Dean Witter Discover and the InterCapital Funds.
 
  With respect to each Trust, each nominee named below has agreed to serve as a
trustee if elected; however, should any nominee(s) become unable or unwilling to
accept nomination or election, the proxies will be voted for one or more
substitute nominee(s) designated by the present Board of Trustees.
 
  The following table sets forth the names, addresses, ages, principal
occupations and other information regarding the Trustee nominees.

(1)The trustees and officers as a group owned less than 1% of the outstanding
   Shares of each Fund.

Discover by nominees during Funds most recent fiscal years.]
 
  During each Fund's respective fiscal year ended in 1996, the Board of Trustees
held between 6 and 9 meetings for each Fund. All of the incumbent nominees to
the Board of Trustees attended at least 75% of the meetings of the respective
Board of Trustees and all committee meetings thereof of which such trustee was a
member during the period of such Trustee's service for each Fund's 1996 fiscal
year. During each Fund's 1996 fiscal year, the Fund had no standing committees
other than an audit committee, a brokerage committee and a retirement plan
committee.
 
  Each Fund's audit committee currently consists of Messrs. Kennedy, Robinson
and Sisto. The audit committee makes recommendations to the Board concerning the
selection of the Fund's independent public accountants, reviews with such
accountants the scope and results of the Fund's annual audit and considers any
comments that the accountants may have regarding the Fund's financial statements
or books of account. Each Fund's brokerage committee currently consists of Ms.
Heagy and Messrs. Branagan and Nelson. The brokerage committee reviews the
Fund's allocation of brokerage transactions and soft-dollar practices. Each
Fund's retirement plan committee currently consists of Ms. Heagy and Messrs.
Kennedy and Nelson. The retirement plan committee is responsible for reviewing
the terms of each Fund's retirement plan and reviews any administrative matters
that arise with respect thereto. The Disinterested Trustees also are responsible
for the annual review of each Fund's investment advisory agreement and any other
matters requiring the approval of the Disinterested Trustees under the 1940 Act.
During each Fund's 1996 fiscal year, the audit committee and the brokerage
committee of each Fund held between 1 and 3 meetings. The retirement plan
committee does not meet on a regular basis, but does meet on an ad hoc basis as
necessary to administer the retirement plan.
 
  The Trustees of each Fund who are not "interested persons" of such Fund (as
defined by the 1940 Act) are required to select and nominate such non-interested
 
                                       23
<PAGE>   31
 
Trustees and are prepared to review nominations from shareholders to fill any
vacancies in trusteeships. Nominations from shareholders should be in writing
and addressed to the non-interested Trustees at the respective Trust's office.
The non-interested Trustees of each Fund expect to be able to identify from
their own resources an ample number of qualified candidates.
 
  Each of the foregoing trustees holds the same position with each of the funds
in the Fund Complex (defined below). As of December 31, 1996, there were 51
funds in the Fund Complex. Each trustee who is not an affiliated person of Asset
Management, the Distributor, VKAC or Morgan Stanley (each a "Non-Affiliated
Trustee") is compensated by an annual retainer and meeting fees for services to
the funds in the Fund Complex. Each fund in the Fund Complex provides a deferred
compensation plan to its Non-Affiliated Trustees that allows trustees to defer
receipt of his or her compensation and earn a return on such deferred amounts
based upon the return of the common shares of the funds in the Fund Complex as
more fully described below. Each fund in the Fund Complex also provides a
retirement plan to its Non-Affiliated Trustees that provides Non-Affiliated
Trustees with compensation after retirement, provided that certain eligibility
requirements are met as more fully described below.
 
  The compensation of each Non-Affiliated Trustee from the Funds and other funds
in the Fund Complex that are advised by the Adviser (the "AC Funds") includes an
annual retainer in an amount equal to $35,000 per calendar year, due in four
quarterly installments on the first business day of each calendar quarter. The
AC Funds pay each Non-Affiliated Trustee a per meeting fee in the amount of
$2,000 per regular quarterly meeting attended by the Non-Affiliated Trustee, due
on the date of such meeting, plus reasonable expenses incurred by the Non-
Affiliated Trustee in connection with his or her services as a trustee. Payment
of the annual retainer and the regular meeting fee is allocated among the AC
Funds (i) 50% on the basis of the relative net assets of each AC Fund to the
aggregate net assets of all the AC Funds and (ii) 50% equally to each AC Fund,
in each case as of the last business day of the preceding calendar quarter. Each
AC Fund which is the subject of a special meeting of the trustees generally pays
each Non-Affiliated Trustee a per meeting fee in the amount of $125 per special
meeting attended by the Non-Affiliated Trustee, due on the date of such meeting,
plus reasonable expenses incurred by the Non-Affiliated Trustee in connection
with his or her services as a trustee, provided that no compensation will be
paid in connection with certain telephonic special meetings.
 
  Each Non-Affiliated Trustee also receives compensation from funds in the Fund
Complex advised by Van Kampen American Capital Investment Advisory Corp. (the
"VK Funds"), which compensation includes an annual retainer in an amount equal
to $2,500 per calendar year, due in four quarterly installments on the first
business day of each calendar quarter. Each Non-Affiliated Trustee receives a
per
 
                                       24
<PAGE>   32
 
meeting fee from each VK Fund in the amount of $125 per regular quarterly
meeting attended by the Non-Affiliated Trustee, due on the date of such meeting,
plus reasonable expenses incurred by the Non-Affiliated Trustee in connection
with his or her services as a trustee. Each Non-Affiliated Trustee receives a
per meeting fee from each VK Fund in the amount of $125 per special meeting
attended by the Non-Affiliated Trustee, due on the date of such meeting, plus
reasonable expenses incurred by the Non-Affiliated Trustee in connection with
his or her services as a trustee, provided that no compensation will be paid in
connection with certain telephonic special meetings.
 
  The trustees approved an aggregate compensation cap with respect to funds in
the Fund Complex of $84,000 per Non-Affiliated Trustee per year (excluding any
retirement benefits) for the period July 22, 1995 through December 31, 1996,
subject to the net assets and the number of funds in the Fund Complex as of July
21, 1995 and certain other exceptions. For the calendar year ended December 31,
1996, certain trustees received aggregate compensation from the funds in the
Fund Complex over $84,000 due to compensation received but not subject to the
cap, including compensation from new funds added to the Fund Complex after July
22, 1995 and certain special meetings in 1996. In addition, each of Asset
Management or Van Kampen American Capital Investment Advisory Corp., as the case
may be, agreed to reimburse each fund in the Fund Complex through December 31,
1996 for any increase in the aggregate trustee's compensation over the aggregate
compensation paid by such fund in its 1994 fiscal year, provided that if a fund
did not exist for the entire 1994 fiscal year appropriate adjustments will be
made.
 
  Each Non-Affiliated Trustee generally can elect to defer receipt of all or a
portion of the compensation earned by such Non-Affiliated Trustee until
retirement. Amounts deferred are retained by the respective Fund and earn a rate
of return determined by reference to the return on the common shares of such
Fund or other funds in the Fund Complex as selected by the respective
Non-Affiliated Trustee, with the same economic effect as if such Non-Affiliated
Trustee had invested in one or more funds in the Fund Complex, including the
Funds. To the extent permitted by the 1940 Act, each Fund may invest in
securities of those funds selected by the Non-Affiliated Trustees in order to
match the deferred compensation obligation. The deferred compensation plan is
not funded and obligations thereunder represent general unsecured claims against
the general assets of the respective Fund.
 
  Each Fund has adopted a retirement plan. Under the retirement plan, a Non-
Affiliated Trustee who is receiving trustee's compensation from a Fund prior to
such Non-Affiliated Trustee's retirement, has at least ten years of service and
retires at or after attaining the age of 60, is eligible to receive a retirement
benefit equal to $2,500 per year for each of the ten years following such
trustee's retirement. Trustees retiring prior to the age of 60 or with fewer
than 10 years but more than
 
                                       25
<PAGE>   33
 
5 years of service may receive reduced retirement benefits from a Fund. The
retirement plan contains a Fund Complex retirement benefit cap of $60,000 per
year. Asset Management has reimbursed the AC Funds for expenses related to the
retirement plan through December 31, 1996.
 
  Additional information regarding compensation and benefits for trustees is set
forth below. As indicated in the notes accompanying the table, the amounts
relate to either the respective Fund's most recently completed fiscal year or
the Fund Complex' most recently completed calendar year ended December 31, 1996.

* Currently a member of each Board of Trustees and a nominee to each Board of
  Trustees to be voted on by shareholders of the Funds at the Meeting.
 
(1) Persons not designated by an asterisk are not currently members of the Board
    of Trustees, but were members of the Board of Trustees during the most
    recently completed fiscal year of one or more of the Funds. Mr. Caruso was
    removed from the Board of Trustees effective September 7, 1995. Messrs.
    Gaughan and Rees retired from the Board of Trustees on January 26, 1996 and
    January 29, 1996, respectively. Mr. Sheehan was removed from the Board of
    Trustees effective January 29, 1996. Messrs. Hilsman, Miller and Woodside
    retired from the Board of Trustees on December 31, 1996. Messrs. McDonnell
    and Powell, trustees for each Trust during all or a portion of each Fund's
    last fiscal year, and Mr. DeMartini, nominee for each Trust, are affiliated
    persons of the Advisers
 
                                       26

    and are not eligible for compensation or retirement benefits from the Funds.
    Mr. Don G. Powell resigned from the Board of Trustees on August 15, 1996.
    Mr. McDonnell, currently a member of the Board of Trustees, is not standing
    for election to the Boards of Trustees at the Meeting.
 
(2) The Aggregate Compensation before Deferral from each Fund during its 1996
    fiscal year is shown in Annex E. Certain trustees deferred all or a portion
    of their 1996 Aggregate Compensation from each Fund as shown in Annex F. The
    cumulative deferred compensation (including interest) from each Fund at the
    end of its last fiscal year is shown in Annex G. The deferred compensation
    plan is described above the 1996 Compensation Table. Amounts deferred are
    retained by the respective Fund and earn a rate of return determined by
    reference to either the return on the common shares of such Fund or other
    funds in the Fund Complex as selected by the respective Non-Affiliated
    Trustee, with the same economic effect as if such Non-Affiliated Trustee had
    invested in one or more funds in the Fund Complex, including the Funds. To
    the extent permitted by the 1940 Act, each Fund may invest in securities of
    those funds selected by the Non-Affiliated Trustees in order to match the
    deferred compensation obligation.
 
(3) The retirement benefits accrued per Fund as part of such Fund's expenses
    during its 1996 fiscal year are shown in Annex H. The Retirement Plan is
    described above the 1996 Compensation Table.
 
(4) This is the estimated maximum annual benefits payable per Fund in each year
    of the 10-year period commencing in the year of such trustee's retirement
    from such Fund assuming: the trustee has 10 or more years of service on the
    Board of the respective Fund and retires at or after attaining the age of
    60. Trustees retiring prior to the age of 60 or with fewer than 10 years of
    service for the respective Fund may receive reduced retirement benefits from
    such Fund. The actual annual benefit may be less if the trustee is subject
    to the Fund Complex retirement benefit cap or if the trustee is not fully
    vested at the time of retirement.
 
(5) The amounts shown in this column represent the aggregate compensation paid
    by all 51 of the investment companies advised by Asset Management or Van
    Kampen American Capital Investment Advisory Corp. that have the same members
    on each fund's Board of Trustees as of December 31, 1996 (the "Fund
    Complex") before deferral by the trustees under the deferred compensation
    plan. Certain trustees deferred all or a portion of their aggregate
    compensation from the Fund Complex during the calendar year ended December
    31, 1996. The deferred compensation earns a rate of return determined by
    reference to the return on the shares of the funds in the Fund Complex as
    selected by the respective Non-Affiliated Trustee, with the same economic
    effect as if such Non-Affiliated Trustee had invested in one or more funds
    in the Fund Complex, including the Funds. To the extent permitted by the
    1940 Act, the Fund may invest in securities
 
                                       27
<PAGE>   35
 
    of those funds selected by the Non-Affiliated Trustees in order to match the
    deferred compensation obligation. The trustees' Fund Complex compensation
    cap covered the period July 22, 1995 through December 31, 1996. For the
    calendar year ended December 31, 1996, certain trustees received
    compensation over $84,000 in the aggregate due to compensation received but
    not subject to the cap, including compensation from new funds added to the
    Fund Complex after July 22, 1995 and certain special meetings in 1996. Asset
    Management, Van Kampen American Capital Investment Advisory Corp. and their
    affiliates also serve as investment adviser for other investment companies;
    however, with the exception of Messrs. McDonnell, Powell and Whalen, the
    trustees were not trustees of such investment companies. Combining the Fund
    Complex with other investment companies advised by Asset Management, Van
    Kampen American Capital Investment Advisory Corp. and their affiliates, Mr.
    Whalen received Total Compensation of $243,375 during the calendar year
    ended December 31, 1996.
 
  Following the Meeting, the Funds do not contemplate holding regular meetings
of shareholders to elect trustees or otherwise. When an investment company does
not hold regular annual meetings, it is the position of the staff of the SEC and
a policy of each Trust that holders of record of two-thirds of the outstanding
shares of such trusts may file a declaration in writing or may vote at a special
meeting for the purpose of removing a trustee. The Board will be required to
promptly call a meeting of shareholders for the purpose of voting upon the
question of removal of any trustee when requested in writing to do so by the
record holders of not less than 10% of the total outstanding shares of such
Trust. In addition, the Board will comply with the requirements of Section 16(c)
of the 1940 Act with respect to communications with shareholders.
 
SHAREHOLDER APPROVAL
 
  The affirmative vote of a plurality of the Shares of a Trust present in person
or by proxy is required to elect the nominees to such Trust. THE BOARDS OF
TRUSTEES OF EACH TRUST RECOMMEND A VOTE "FOR" EACH OF THE NOMINEES.
- ------------------------------------------------------------------------------
PROPOSAL 4: AMENDMENTS TO FUNDAMENTAL INVESTMENT POLICIES OF HIGH INCOME
            CORPORATE BOND FUND
- ------------------------------------------------------------------------------
 
  The primary investment objective of the High Income Corporate Bond Fund is to
maximize current income. Capital appreciation is a secondary investment
objective which is sought only when consistent with the primary investment
objective.
 
  The High Income Corporate Bond Fund has certain fundamental investment
restrictions, which may be amended only with shareholder approval. At a meeting
of the Board of Trustees on March 27, 1997, Asset Management recommended to
 
                                       28
<PAGE>   36
 
the Board of Trustees the termination or amendment of three such investment
restrictions that Asset Management believes no longer are in the best interests
of the High Income Corporate Bond Fund or its shareholders.
 
  The proposed amendments to the fundamental investment restrictions of the High
Income Corporate Bond Fund are not related to the Merger described in Proposal
1. Shareholders are being asked to consider such amendments at this time because
the High Income Corporate Bond Fund does not hold regular annual shareholder
meetings, and management believes that submitting these amendments to
shareholders together with the other proposals in this Proxy Statement will
reduce the expenses incurred by the High Income Corporate Bond Fund in
connection with soliciting approval of these amendments.
 
PROPOSAL 4A: AMENDMENT TO POLICY REGARDING UNSEASONED ISSUERS
 
  The High Income Corporate Bond Fund currently has a fundamental investment
restriction that prohibits it from investing in securities of issuers that have
been in continuous operation for less than three years, which issuers sometimes
are referred to as "unseasoned issuers". Investment in the securities of
unseasoned issuers may be riskier than investing in securities issued by more
seasoned issuers, because unseasoned issuers have less operating history and
less information may be available with respect to unseasoned issuers. Asset
Management believes, however, that securities of unseasoned issuers may from
time to time present attractive investment opportunities for the High Income
Corporate Bond Fund and that terminating this fundamental investment restriction
would provide Asset Management with additional flexibility in seeking to achieve
the High Income Corporate Bond Fund's investment objective of maximizing current
income.
 
PROPOSAL 4B: AMENDMENT TO POLICY REGARDING DIVERSIFICATION
 
  The High Income Corporate Bond Fund is registered under the 1940 Act as a
"diversified" investment company. A "diversified" investment company is
permitted to use up to 25% of its total assets to acquire more than 10% of the
outstanding voting securities of any one issuer. The High Income Corporate Bond
Fund, however, currently has a fundamental investment restriction that prohibits
it from purchasing more than 10% of any one class of securities of any one
issuer. Asset Management has recommended terminating this restriction in order
to permit the High Income Corporate Bond Fund to exercise the full flexibility
permitted to a "diversified" investment company under the 1940 Act. The purchase
of more than 10% of the outstanding securities of any one issuer will make the
High Income Corporate Bond Fund more susceptible to the risks associated with an
investment in the securities of such issuer. Asset Management believes, however,
that from time to time it may be in the High Income Corporate Bond Fund's best
interest to purchase more than 10% of the securities of an issuer, if the
securities of such issuer represent an attractive investment opportunity and
that terminating this fundamental
 
                                       29
<PAGE>   37
 
investment restriction would provide Asset Management with additional
flexibility in seeking to achieve the High Income Corporate Bond Fund's
investment objective of maximizing current income.
 
PROPOSAL 4C: AMENDMENT TO POLICY REGARDING FOREIGN SECURITIES
 
  The High Income Corporate Bond Fund currently has a fundamental investment
restriction that prohibits it from investing more than 20% of its total assets
in dollar denominated debt securities issued by foreign governments or other
foreign issuers, or investing more than 10% of its total assets in securities
which are payable in currencies other than U.S. dollars. Asset Management has
recommended amending this restriction to permit the High Income Corporate Bond
Fund to invest up to 35% of its total assets in debt securities issued by
foreign governments and other foreign issuers or which are payable in currencies
other than U.S. dollars. Amending this investment restriction will make the High
Income Corporate Bond Fund more susceptible to risks associated with investment
in foreign securities, including changes in currency rates, political or
economic instability in the country of a security's issuer, less publicly
available information about foreign issuers, less rigorous financial reporting
requirements applicable to foreign issuers, expropriation and confiscatory
taxation. In the event of a default of foreign issuers, it may be more difficult
for the High Income Corporate Bond Fund to obtain or enforce judgment against
the issuer of such securities. Asset Management believes that from time to time
foreign debt securities may provide higher yields than debt securities of
domestic issuers with similar maturities. Asset Management believes that
amending this investment restriction will grant Asset Management greater
flexibility in seeking to achieve the High Income Corporate Bond Fund's
investment objective of maximizing current income and is in the best interest of
the High Income Corporate Bond Fund and its shareholders.
 
SHAREHOLDER APPROVAL
 
  To become effective, each proposed amendment to the High Income Corporate Bond
Fund's investment restrictions must be separately approved by the vote of a
majority of the High Income Corporate Bond Fund's outstanding voting securities.
The "vote of a majority of the outstanding voting securities" is defined in the
1940 Act as the lesser of the vote of (i) 67% or more of the Shares of the High
Income Corporate Bond Fund entitled to vote thereon present at the Meeting if
the holders of more than 50% of such outstanding Shares are present in person or
represented by proxy; or (ii) more than 50% of such outstanding Shares of the
High Income Corporate Bond Fund entitled to vote thereon. An unfavorable vote on
the proposed amendment to any one of the fundamental investment restrictions
will not affect the implementation of the proposed amendments to other
fundamental investment restrictions, if the proposed amendments to the other
fundamental investment restrictions are approved. The proposed amendments were
approved by
 
                                       30
<PAGE>   38
 
the Board of Trustees of the High Income Corporate Bond Fund after consideration
of all the factors they determined to be relevant to their deliberations,
including those discussed above. The Board of Trustees also unanimously
determined to submit the proposed changes to the shareholders of the High Income
Corporate Bond Fund. THE BOARD OF TRUSTEES OF THE HIGH INCOME CORPORATE BOND
FUND RECOMMENDS A VOTE "FOR" APPROVAL OF EACH AMENDED INVESTMENT RESTRICTION.
- ------------------------------------------------------------------------------
PROPOSAL 5: AMENDMENT TO FUNDAMENTAL INVESTMENT POLICIES OF HARBOR FUND
- ------------------------------------------------------------------------------
 
  The primary investment objective of the Harbor Fund is to seek to provide
current income, capital appreciation and conservation of capital. The Harbor
Fund seeks to achieve its investment objective by investing principally in debt
securities, primarily convertible bonds and convertible preferred stocks.
 
  The Harbor Fund has a fundamental investment restriction that permits it to
invest in real estate investment trusts ("REITs") that invest only in mortgages
or other security interests in real estate ("Mortgage REITs"), but prohibits the
Harbor Fund from investing in real estate investment trusts that invest directly
in real estate ("Equity REITs").
 
  At a meeting of the Board of Trustees on March 27, 1997, Asset Management
recommended to the Board of Trustees amending the Harbor Fund's investment
restriction with respect to REITs to permit the Harbor Fund to invest in Equity
REITs. Historically, the total return of Equity REITs generally has been less
volatile than the total return of Mortgage REITs. Equity REITs and Mortgage
REITs alternatively have experienced higher total returns depending on the time
period analyzed. Mortgage REITs generally have experienced higher yields. Asset
Management believes that the majority of REITs have the capability to invest
directly in real estate and that amending the Harbor Fund's investment
restriction with respect to investment in REITs will materially increase the
number of REITs in which the Harbor Fund may invest. Asset Management believes
that amending this investment restriction will grant Asset Management greater
flexibility in seeking to achieve the Harbor Fund's investment objective because
the Harbor Fund would be permitted to invest in a greater number and variety of
REITs. Asset Management believes that this amendment is in the best interest of
the Harbor Fund and its shareholders.
 
  The proposed amendment to the Harbor Fund's fundamental investment restriction
is not related to the Merger described in Proposal 1. Shareholders are being
asked to consider the amendment at this time because the Harbor Fund does not
hold regular annual shareholder meetings, and management believes that
submitting this proposal to shareholders together with the other proposals in
this Proxy Statement will reduce the expenses incurred by the Harbor Fund in
connection with soliciting approval of this amendment.

SHAREHOLDER APPROVAL
 
  To become effective, the proposed amendment to the Harbor Fund's investment
restriction with respect to investments in REITs must be approved by the vote of
a majority of the Harbor Fund's outstanding voting securities. The "vote of a
majority of the outstanding voting securities" is defined in the 1940 Act as the
lesser of the vote of (i) 67% or more of the Shares of the Harbor Fund entitled
to vote thereon present at the Meeting if the holders of more than 50% of such
outstanding Shares are present in person or represented by proxy; or (ii) more
than 50% of such outstanding Shares of the Harbor Fund entitled to vote thereon.
The proposed amendment was approved by the Board of Trustees of the High Income
Corporate Bond Fund after consideration of all the factors they determined to be
relevant to their deliberations, including those discussed above. The Board of
Trustees also unanimously determined to submit the proposed changes to the
shareholders of the Harbor Fund. THE BOARD OF TRUSTEES OF THE HARBOR FUND
RECOMMENDS A VOTE "FOR" APPROVAL OF THE AMENDED INVESTMENT RESTRICTION.
- ------------------------------------------------------------------------------
PROPOSAL 6: RATIFICATION OF INDEPENDENT PUBLIC
               ACCOUNTANTS FOR FUNDS
- ------------------------------------------------------------------------------
 
  The Board of Trustee of each Fund, including a majority of the Trustees who
are not "interested persons" of each Fund (as defined by the 1940 Act), has
selected the firm of Price Waterhouse LLP, independent public accountants, to
examine the financial statements for the current fiscal year of each Fund. Each
Fund knows of no direct or indirect financial interest of such firm in such
Funds. The appointment is subject to ratification or rejection by the
shareholders of each Fund. It is expected that Price Waterhouse LLP will also
act as independent public accountants for VKAC Holding, VKAC, Advisory Corp.,
Asset Management, the Distributor (defined below) and ACCESS (defined below).
 
  Representatives of Price Waterhouse LLP are expected to be present at the
Meeting and will be available to respond to questions from shareholders and will
have the opportunity to make a statement if they so desire.
 
SHAREHOLDER APPROVAL
 
  The shareholders of each Fund, voting with respect to such Fund as a single
class, are entitled to vote on this proposal. An affirmative vote of a majority
of the Shares of each Fund present in person or by proxy and voting is required
to ratify the selection of the independent public accountants for such Fund. THE
BOARD OF TRUSTEES OF EACH FUND RECOMMENDS A VOTE "FOR" RATIFICATION OF PRICE
WATERHOUSE LLP AS INDEPENDENT PUBLIC ACCOUNTANTS FOR THE CURRENT FISCAL YEAR OF
EACH FUND.

  The officers of the Funds serve for one year or until their respective
successors are chosen and qualified. The Funds' officers receive no compensation
from the Funds, but are all officers of the Adviser, the Distributor, VKAC or
their affiliates and receive compensation in such capacities.
 
NON-ADVISORY AGREEMENTS
 
  In connection with the Board of Trustee's review and approval of the New
Advisory Agreements as described above, the Board of Trustees reviewed and
approved certain other agreements with the Adviser, VKAC, the Distributor and
ACCESS. These agreements do not need to be voted on by the shareholders of the
Funds at the Meeting. The Adviser currently anticipates that the services
provided to the Funds pursuant to these agreements will continue to be provided
after the proposed New Advisory Agreements are approved.
 
  Distribution Agreement, Distribution Plan and Service Plan. Each Fund has
entered into a distribution agreement with the Distributor pursuant to which the
Distributor, as principal underwriter, purchases shares for resale to the
public, either directly or through securities dealers. In connection with their
consideration of the
 
                                       35
<PAGE>   43
 
Merger, the Boards of Trustees considered the affects of the Merger on the
Distributor and the ability of the Distributor to continue distributing the
shares of the Funds. The new distribution agreement between each Fund and the
Distributor is substantially similar to the current distribution agreement,
except that the new distribution agreement designates certain officers of the
Distributor and the officers of the Fund to be essential personnel with respect
to the operations of the Fund. The Distributor may not make any material or
significant personnel changes or replace any essential personnel or materially
change the responsibilities or duties of any essential personnel prior to the
first anniversary of the agreement without first informing the Board of Trustees
in a timely manner. In addition, the Distributor may not distribute shares of
any investment companies other than the Funds without the prior approval of the
Board of Trustees. The Distributor may not change its name without the prior
consent of the Board of Trustees. Under each distribution agreement, each Fund
paid the Distributor the amount set forth Annex D hereto for its most recently
completed fiscal year.
 
  Each Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
Each Fund also has adopted a service plan (the "Service Plan") with respect to
each class of its shares. The Distribution Plan and the Service Plan provide
that the Fund may pay to the Distributor a portion of the Fund's average daily
net assets attributable to each class of shares in connection with distribution
of the respective class of shares and in connection with the provision of
ongoing services to shareholders of each class. The Distribution Plan and the
Service Plan are implemented through an agreement with the Distributor. The
Distributor has entered into sub-agreements with certain members of the NASD who
are acting as securities dealers, as well as NASD members or eligible
non-members who are acting as brokers or agents. The Funds have entered into
similar agreements with financial intermediaries who are acting as brokers that
may provide for their customers or clients certain services or assistance. The
agreements between the Distributor and certain brokers, dealers and agents and
the agreements between the Funds and certain financial intermediaries, which
agreements implement the Distribution Plan and the Service Plan, are referred to
herein collectively as the "Selling Agreements." Brokers, dealers and financial
intermediaries that have entered into Selling Agreements with the Distributor
and sell shares of the Fund are referred to herein as "financial
intermediaries."
 
  Each Fund may spend an aggregate amount of up to 0.25% per year of the average
daily net assets attributable to the Class A Shares of the respective Fund
pursuant to the Distribution Plan and the Service Plan. From such amount, each
Fund may spend up to the full 0.25% per year of its average daily net assets
attributable to the Class A Shares pursuant to the Service Plan in connection
with the ongoing provision of services to holders of such shares by the
Distributor and by financial intermediaries and in connection with the
maintenance of shareholders'
 
                                       36
<PAGE>   44
 
accounts. Each Fund pays the Distributor the lesser of the balance of the 0.25%
not paid to such financial intermediaries or the amount of the Distributor's
actual distribution related expenses.
 
  Each Fund may spend up to 0.75% per year of its average daily net assets
attributable to its Class B Shares pursuant to the Distribution Plan. In
addition, each Fund may spend up to 0.25% per year of the Fund's average daily
net assets attributable to the Class B Shares pursuant to the Service Plan in
connection with the ongoing provision of services to holders of such shares by
the Distributor and by financial intermediaries and in connection with the
maintenance of such shareholders' accounts.
 
  Each Fund may spend up to 0.75% per year of the average daily net assets
attributable to its Class C Shares pursuant to the Distribution Plan. From such
amount, the Fund, or the Distributor as agent for the Fund, pays financial
intermediaries in connection with the distribution of the Class C Shares up to
0.75% of the Fund's average daily net assets attributable to Class C Shares
maintained in the Fund more than one year by such financial intermediary's
customers. In addition, each Fund may spend up to 0.25% per year of the
respective Fund's average daily net assets attributable to the Class C Shares
pursuant to the Service Plan in connection with the ongoing provision of
services to holders of such shares by the Distributor and by financial
intermediaries and in connection with the maintenance of such shareholders'
accounts.
 
  Amounts payable to the Distributor with respect to the Class A Shares under
the Distribution Plan in a given year may not fully reimburse the Distributor
for its actual distribution-related expenses during such year. In such event,
with respect to the Class A Shares, there is no carryover of such reimbursement
obligations to succeeding years.
 
  The Distributor's actual expenses with respect to Class B Shares and Class C
Shares sold subject to a contingent deferred sales charge ("CDSC Shares") for
any given year may exceed the amounts payable to the Distributor with respect to
the CDSC Shares under the Distribution Plan, the Service Plan and payments
received pursuant to the contingent deferred sales charge. In such event, with
respect to the CDSC Shares, any unreimbursed expenses will be carried forward
and paid by the Fund (up to the amount of the actual expenses incurred) in
future years so long as such Distribution Plan is in effect. Except as mandated
by applicable law, the Funds do not impose any limit with respect to the number
of years into the future that such unreimbursed distribution expenses may be
carried forward (on a Fund level basis). Because such expenses are accounted for
on a Fund-wide basis, a particular CDSC Share may be greater or less than the
amount of the initial commission (including carrying cost) paid by the
Distributor with respect to such CDSC Share.
 
  The address of the Distributor is One Parkview Plaza, Oakbrook Terrace,
Illinois 60181.

  Following the Merger, the Adviser will be an affiliate of Morgan Stanley & Co.
and DWR, each a registered broker-dealer. The amount of commissions paid by each
Fund to Morgan Stanley & Co. and DWR, if any, during its most recently completed
fiscal year is set forth on Annex D to this Proxy Statement.
 
  Transfer Agency Agreement. Each Fund has entered into a Transfer Agency
Agreement with ACCESS pursuant to which ACCESS provides transfer agency and
dividend disbursing services for such Fund. The address of ACCESS is 7501
Tiffany Springs Parkway, Kansas City, Missouri 64153. For its services, ACCESS
charges each Fund a fee that is determined in accordance with a cost allocation
model developed in conjunction with, and periodically reviewed by, Coopers &
Lybrand LLP. The model allocates among the Funds ACCESS's cost of providing the
Funds with transfer agency services, plus a profit margin approved by the Board
of Trustees. The allocation is based upon a number of factors including the
number of shareholder accounts per Fund, the number and type of shareholder
transactions experienced by each Fund and other factors. Under the Transfer
Agency Agreement, each Fund paid ACCESS the amount set forth at Annex D hereto
for its most recently completed fiscal year. In connection with their
consideration of the Merger, the Boards of Trustees considered the effects of
the Merger on ACCESS and the ability of ACCESS to continue to provide transfer
agency and dividend disbursing services to the Funds. The new Transfer Agency
Agreement between the Funds and ACCESS is substantially similar to the current
Transfer Agency Agreement, except that the new Transfer Agency Agreement
designates certain officers of the transfer agent and the officers of the Fund
to be essential personnel. ACCESS may not make any material or significant
personnel changes or replace any essential personnel or materially change their
duties and responsibilities prior to the first anniversary of the agreement
without first informing the Board of Trustees in a timely manner.
 
  Fund Accounting Agreement. Each Fund has entered into an accounting services
agreement with Advisory Corp. pursuant to which Advisory Corp. provides
accounting services supplementary to those provided by the Fund's custodian. The
Board of Trustees of each Fund has approved an amendment to each Fund's
accounting services agreement whereby Advisory Corp. will assume responsibility
for providing accounting services currently provided by the custodian of each
Fund's assets, and it is currently anticipated that Advisory Corp. will assume
responsibility for providing such services. Each AC Fund is party to the Fund
Accounting Agreement, and currently receives all accounting services through
Advisory Corp. Each Fund shares equally, together with the other mutual funds
advised and distributed by the Advisers and the Distributor, respectively, in
25% of the cost of providing such services, with the remaining 75% of such cost

  Legal Services Agreement. Each VK Fund has entered into a Legal Services
Agreement pursuant to which VKAC provides legal services, including without
limitation maintenance of the VK Funds' minute books and records, preparation
and oversight of the VK Funds' regulatory reports, and other information
provided to shareholders, as well as responding to day-to-day legal issues.
Payment by each VK Fund for such services is made on a cost basis for the
employment of personnel as well as the overhead and equipment necessary to
render such services. Under the Legal Services Agreement, each VK Fund paid VKAC
the amount set forth at Annex D hereto for its most recently completed fiscal
year. VKAC also provides legal services for the AC Funds, which do not currently
reimburse VKAC for the provision of such services. VKAC allocates 50% of its
costs equally to each Fund and the remaining 50% of such costs are allocated to
specific Funds based on specific time allocations, or in the event services are
attributable only to types of investment companies (i.e. closed-end or
open-end), the relative amount of time spent on each type of investment
companies and then further allocated among Funds of that type based upon their
respective net asset values.

considered for presentation at a shareholders' meeting, rules promulgated by the

UNITED STATES.

                         INVESTMENT ADVISORY AGREEMENT
 
AGREEMENT (herein so called) made this [DATE], by and between VAN KAMPEN
AMERICAN CAPITAL                              FUND, a Delaware business trust
(hereinafter referred to as the "FUND"), and VAN KAMPEN AMERICAN CAPITAL ASSET
MANAGEMENT, INC., a Delaware corporation (hereinafter referred to as the
"ADVISER").
 
The FUND and the ADVISER agree as follows:
 
(1) SERVICES RENDERED AND EXPENSES PAID BY ADVISER
 
  The ADVISER, subject to the control, direction and supervision of the FUND's
Trustees and in conformity with applicable laws, the FUND's Agreement and
Declaration of Trust ("Declaration of Trust"), By-laws, registration statements,

    a. manage the investment and reinvestment of the FUND's assets including, by

  portfolio investments for the FUND's account with brokers or dealers selected
  by the ADVISER;
 
    c. conduct and manage the day-to-day operations of the FUND including, by
  way of illustration, the preparation of registration statements, prospectuses,

appropriate policies and procedures, the ADVISER may, to the extent authorized
by law, cause the FUND to pay a broker or dealer that provides brokerage and
research services to the ADVISER an amount of commission for effecting a
portfolio investment transaction in excess of the amount of commission another
broker or dealer would have charged for effecting that transaction. In the event
of such authorization and to the extent authorized by law, the ADVISER shall not
be deemed to have acted unlawfully or to have breached any duty created by this
Agreement or otherwise solely by reason of such action.
 
  Except as otherwise agreed, or as otherwise provided herein, the FUND shall
pay, or arrange for others to pay, all its expenses other than those expressly

basis for the FUND's financial statements, preparation of such financial
statements and other FUND documents and reports of a financial nature required
by federal and state laws, and participation in the production of the FUND's
registration statement, prospectuses, proxy solicitation materials and reports
to shareholders; (v) fees of outside counsel to and of independent accountants
of the FUND selected by the Trustees; (vi) custodian, registrar and shareholder
service agent fees and expenses; (vii) expenses related to the repurchase or
redemption of its shares including expenses related to a program of periodic

premiums for fidelity coverage and errors and omissions insurance; (xiv) dues
for the FUND's membership in trade associations approved by the Trustees; and
(xv) such nonrecurring expenses as may arise, including those associated with
actions, suits or proceedings to which the FUND is a party and the legal

respect thereto. To the extent that any of the foregoing expenses are allocated
 
                                      B1-2
<PAGE>   51
 
between the FUND and any other party, such allocations shall be pursuant to
methods approved by the Trustees.
 
  For a period of one year commencing on the effective date of this Agreement,
the ADVISER and the FUND agree that the retention of (i) the chief executive
officer, president, chief financial officer and secretary of the ADVISER and
(ii) each director, officer and employee of the ADVISER or any of its Affiliates
(as defined in the Investment Company Act of 1940, as amended (the "1940 Act"))
who serves as an officer of the FUND each person referred to in (i) or (ii)
hereinafter being referred to as an "Essential Person"), in his or her current
capacities, is in the best interest of the FUND and the FUND'S shareholders. In
connection with the ADVISER'S acceptance of employment hereunder, the ADVISER
hereby agrees and covenants for itself and on behalf of its Affiliates that
neither the ADVISER nor any of its Affiliates shall make any material or
significant personnel changes or replace or seek to replace any Essential Person
or cause to be replaced any Essential Person, in each case without first
informing the Board of Trustees of the FUND in a timely manner. In addition,
neither the ADVISER nor any Affiliate of the ADVISER shall change or seek to
change or cause to be changed, in any material respect, the duties and
responsibilities of any Essential Person, in each case without first informing
the Board of Trustees of the FUND in a timely manner.
 
(2) ROLE OF ADVISER
 
  The ADVISER, and any person controlled by or under common control with the
ADVISER, shall be free to render similar services to others and engage in other
activities, so long as the services rendered to the FUND are not impaired.
 
  Except as otherwise required by the Investment Company Act of 1940 (the "1940
Act"), any of the shareholders, trustees, officers and employees of the FUND may
be a shareholder, trustee, director, officer or employee of, or be otherwise
interested in, the ADVISER, and in any person controlled by or under common
control with the ADVISER, and the ADVISER, and any person controlled by or under
common control with the ADVISER, may have an interest in the FUND.
 
  Except as otherwise agreed, in the absence of willful misfeasance, bad faith,
negligence or reckless disregard of obligations or duties hereunder on the part
of the ADVISER, neither the ADVISER nor any subadviser shall be subject to
liability to the FUND, or to any shareholder of the FUND, for any act or
omission in the course of, or connected with, rendering services hereunder or
for any losses that may be sustained in the purchase, holding or sale of any
security.
 
                                      B1-3
<PAGE>   52
 
(3) COMPENSATION PAYABLE TO ADVISER
 
  The FUND shall pay to the ADVISER, as compensation for the services rendered,
facilities furnished and expenses paid by the ADVISER, a monthly fee computed at
the following annual rate:
 
                            [advisory fee schedule]
 
  Average daily net assets shall be determined by taking the average of the net
assets for each business day during a given calendar month calculated in the
manner provided in the FUND's Declaration of Trust. Such fee shall be payable
for each calendar month as soon as practicable after the end of that month.
 
  The fees payable to the ADVISER by the FUND pursuant to this Section 3 shall
be reduced by any commissions, tender solicitation and other fees, brokerage or
similar payments received by the ADVISER, or any other direct or indirect
majority owned subsidiary of VK/AC Holding, Inc., in connection with the
purchase and sale of portfolio investments of the FUND, less any direct expenses
incurred by such person, in connection with obtaining such commissions, fees,
brokerage or similar payments. The ADVISER shall use its best efforts to
recapture all available tender offer solicitation fees and exchange offer fees
in connection with the FUND's portfolio transactions and shall advise the
Trustees of any other commissions, fees, brokerage or similar payments which may
be possible for the ADVISER or any other direct or indirect majority owned
subsidiary of VK/AC Holding, Inc. to receive in connection with the FUND's
portfolio transactions or other arrangements which may benefit the FUND.
 
  [In the event that the ordinary business expenses of the FUND for any fiscal
year should exceed the most restrictive expense limitation applicable in the
states where the FUND's shares are qualified for sale, the compensation due the
ADVISER for such fiscal year shall be reduced by the amount of such excess. The
Adviser's compensation shall be so reduced by a reduction or a refund thereof,
at the time such compensation is payable after the end of each calendar month
during such fiscal year of the FUND, and if such amount should exceed such
monthly compensation, the ADVISER shall pay the FUND an amount sufficient to
make up the deficiency, subject to readjustment during the FUND's fiscal year.
For purposes of this paragraph, all ordinary business expenses of the FUND shall
include the investment advisory fee and other operating expenses paid by the
FUND except (i) for interest and taxes; (ii) brokerage commissions; (iii) as a
result of litigation in connection with a suit involving a claim for recovery by
the FUND; (iv) as a result of litigation involving a defense against a liability
asserted against the FUND, provided that, if the ADVISER made the decision or
took the actions which resulted in such claim, it acted in good faith without
negligence or misconduct; (v) any indemnification paid by the FUND to its
officers and trustees and the ADVISER in accordance with applicable state and
federal laws as a result
 
                                      B1-4
<PAGE>   53
 
of such litigation; and (vi) amounts paid to Van Kampen American Capital
Distributors, Inc., the distributor of the FUND's shares, in connection with a
distribution plan adopted by the FUND's Trustees pursuant to Rule 12b-1 under
the Investment Company Act of 1940.]
 
  If the ADVISER shall serve for less than the whole of any month, the foregoing
compensation shall be prorated.
 
(4) BOOKS AND RECORDS
 
  In compliance with the requirements of Rule 31a-3 under the 1940 Act, the
ADVISER hereby agrees that all records which it maintains for the FUND are the
property of the FUND and further agrees to surrender promptly to the FUND any of
such records upon the FUND's request. The ADVISER further agrees to preserve for
the periods prescribed by Rule 31a-2 under the 1940 Act the records required to
be maintained by Rule 31a-1 under the Act.
 
(5) DURATION OF AGREEMENT
 
  This Agreement shall become effective of the date hereof, and shall remain in
full force until May 31, 1999 unless sooner terminated as hereinafter provided.
This Agreement shall continue in force from year to year thereafter, but only so
long as such continuance is approved at least annually by the vote of a majority
of the FUND's Trustees who are not parties to this Agreement or interested
persons of any such parties, cast in person at a meeting called for the purpose
of voting on such approval, and by a vote of a majority of the FUND's Trustees
or a majority of the FUND's outstanding voting securities.
 
  This Agreement shall terminate automatically in the event of its assignment.
The Agreement may be terminated at any time by the FUND's Trustees, by vote of a
majority of the FUND's outstanding voting securities, or by the ADVISER, on 60
days' written notice, or upon such shorter notice as may be mutually agreed
upon. Such termination shall be without payment of any penalty.
 
(6) MISCELLANEOUS PROVISIONS
 
  For the purposes of this Agreement, the terms "affiliated person,"
"assignment," "interested person," and "majority of the outstanding voting
securities" shall have their respective meanings defined in the 1940 Act and the
Rules and Regulations thereunder, subject, however, to such exemptions as may be
granted to either the ADVISER or the FUND by the Securities and Exchange
Commission (the "Commission"), or such interpretive positions as may be taken by
the Commission or its staff, under the 1940 Act, and the term "brokerage and
research services" shall have the meaning given in the Securities Exchange Act
of 1934 and the Rules and Regulations thereunder.

by the sole shareholder. This Agreement is executed on behalf of the Fund or the

property of the FUND. A Certificate of Trust in respect of the Fund is on file
with the Secretary of State of Delaware.
 
  All questions concerning the validity, meaning and effect of this Agreement
shall be determined in accordance with the laws (without giving effect to the
conflict-of-laws principles thereof) of the State of Delaware applicable to

WHEREAS, Morgan Stanley Asset Management Inc. ("MSAM") has available a staff of

of 1940 (the "1940 Act")) approved by the Trustees as sub-custodians.
 
  (d) Persons authorized by resolution of the Trustees shall have the right to
inspect and copy contracts, notes, vouchers, and copies of entries in books or
electronic recording media relating to the Fund's transactions at the registered
office of MSAM at any time during normal business hours. Such records, in
relation to each transaction effected by MSAM on behalf of the Fund shall be
maintained by MSAM for a period of seven years from the date of such
transaction.
 
1.3 Purchase and Sale of Securities
 
  In performing the services described above, MSAM shall use its best efforts to
obtain for the Fund the most favorable price and execution available. Subject to
prior authorization of appropriate policies and procedures by the Trustees, MSAM
may, to the extent authorized by law, cause the Fund to pay a broker or dealer
who provides brokerage and research services an amount of commission for
effecting the Fund's investment transaction in excess of the amount of
commission another broker or dealer would have charged for effecting that
transaction, in recognition of the brokerage and research services provided by
the broker or dealer. To the extent authorized by law, MSAM shall not be deemed
to have acted unlawfully or to have breached any duty created by this Agreement
or otherwise solely by reason of such action.
 
1.4 Custodian
 
  MSAM shall not act as Custodian for the securities or any other assets of the
Fund. All such assets shall be held by the Custodian or Sub-Custodian appointed
by the Trustees.

2. DUTIES OF VKAC
 
2.1 Provision of Information
 
  VKAC shall advise MSAM from time to time with respect to the Fund of its
investment objectives and of any changes or modifications thereto, as well as
any specific investment restrictions or limitations by sending to MSAM a copy of
each registration statement relating to the Fund as filed with the Securities
and Exchange Commission. As requested by MSAM, VKAC shall furnish such
information to MSAM as to holdings, purchases, and sales of the securities under
its management as will reasonably enable MSAM to furnish its investment advice
under this Agreement.
 
2.2 Compensation to MSAM
 
  The fee for the services provided under this Agreement will be determined as
follows:
 
    (a) An amount for each month (or such other valuation period as may be
  mutually agreed upon) equivalent, on an annual basis, to 50% of the
  compensation actually received by VKAC pursuant to the investment advisory fee
  schedule set forth in the Investment Advisory Agreement between the Fund and
  VKAC taking into account any waiver or return to the Fund of any or all of
  such advisory fee by VKAC (with any such return of fees to be treated as if
  not actually received). The value of the assets of the Fund shall be computed
  as of the close of business on the last day of each valuation period for the
  Fund, using the average of all the daily determinations of the net value of
  the assets of the Fund.
 
    (b) The foregoing fee shall be paid in cash by VKAC to MSAM within five (5)
  business days after the last day of the valuation period.
 
3. MISCELLANEOUS
 
3.1 Activities of MSAM
 
  The services of MSAM as Sub-Adviser to VKAC under this Agreement are not to be
deemed exclusive, MSAM and its affiliates being free to render services to
others. It is understood that shareholders, trustees, officers and employees of
MSAM may become interested in the Fund or VKAC as a shareholder, trustee,
officer, partner or otherwise.
 
3.2 Services to Other Clients
 
  VKAC acknowledges that MSAM may have investment responsibilities, or render
investment advice to, or perform other investment advisory services for, other
individuals or entities ("Clients"). Subject to the provisions of this
paragraph, VKAC agrees that MSAM may give advice or exercise investment
responsibility and take such other action with respect to such Clients which may
differ from advice given or the timing or nature of action taken with respect to
the Fund,
 
                                      B2-4
<PAGE>   59
 
provided that MSAM acts in good faith, and provided, further, that it is MSAM
policy to allocate, within its reasonable discretion, investment opportunities
to the Fund over a period of time on a fair and equitable basis relative to the
Clients, taking into account the investment objectives and policies of the Fund
and any specific investment restrictions applicable thereto. VKAC acknowledges
that one or more of the Clients may at any time hold, acquire, increase,
decrease, dispose of or otherwise deal with positions in investments in which
the Fund may have an interest from time to time, whether in transactions which
may involve the Fund or otherwise. MSAM shall have no obligation to acquire for
the Fund a position in any investment which any Client may acquire, and VKAC
shall have no first refusal, coinvestment or other rights in respect of any such
investment, either for the Fund or otherwise.
 
3.3 Best Efforts
 
  It is understood and agreed that in furnishing the investment advice and other
services as herein provided, MSAM shall use its best professional judgment to
recommend actions which will provide favorable results for the Fund. MSAM shall
not be liable to the Fund or to any shareholder of the Fund to any greater
degree than VKAC.
 
3.4 Duration of Agreement
 
  a) This Agreement, unless terminated pursuant to paragraph b or c below or
Section 2.2(c), shall continue in effect through May 31, 1999, and thereafter
shall continue in effect from year to year, provided its continued applicability
is specifically approved at least annually by the Trustees or by a vote of the
holders of a majority of the outstanding shares of the Fund. In addition, such
continuation shall be approved by vote of a majority of the Trustees who are not
parties to this Agreement or interested persons of any such party, cast in
person at a meeting called for the purpose of voting on such approval. As used
in this paragraph, the term "interested person" shall have the same meaning as
set forth in the 1940 Act.
 
  b) This Agreement may be terminated by sixty (60) days' written notice by
either VKAC or MSAM to the other party. The Agreement may also be terminated at
any time, without the payment of any penalty, by the Fund (by vote of the
Trustees or, by the vote of a majority of the outstanding voting securities of
such Fund), on sixty (60) days' written notice to both VKAC and MSAM. This
Agreement shall automatically terminate in the event of the termination of the
investment advisory agreement between VKAC and the Fund.
 
  c) This Agreement shall terminate in the event of its assignment. The term
"assignment" for this purpose shall have the same meaning set forth in Section
2(a)(4) of the 1940 Act.
 
  d) Termination shall be without prejudice to the completion of any
transactions which MSAM shall have committed to on behalf of the Fund prior to
the time of
 
                                      B2-5

termination. MSAM shall not effect and the Fund shall not be entitled to
instruct MSAM to effect any further transactions on behalf of the Fund
subsequent to the time termination takes effect.
 
  e) This Agreement shall terminate forthwith by notice in writing on the
happening of any of the following events:
 
     i) if VKAC or MSAM shall go into liquidation (except a voluntary
  liquidation for the purpose of and followed by a bona fide reconstruction or
  amalgamation upon terms previously approved in writing by the party not in
  liquidation) or if a receiver or receiver and manager of any of the assets of
  any of them is appointed; or
 
    ii) if either of the parties hereto shall commit any breach of the
  provisions hereof and shall not have remedied such breach within 30 days after
  the service of notice by the party not in breach on the other requiring the
  same to be remedied.
 
  f) On the termination of this Agreement and completion of all matters referred
to in the foregoing paragraph (d) MSAM shall deliver or cause to be delivered to
the Fund copies of all documents, records and books of the Fund required to be
maintained pursuant to Rules 31a-1 or 31a-2 of the 1940 Act which are in MSAM's
possession, power or control and which are valid and in force at the date of
termination.

                VAN KAMPEN AMERICAN CAPITAL TAX-EXEMPT TRUST --
             VAN KAMPEN AMERICAN CAPITAL HIGH YIELD MUNICIPAL FUND
                             SUBADVISORY AGREEMENT
            (MARKED TO SHOW CHANGES FROM CURRENT ADVISORY AGREEMENT)
 
THIS AGREEMENT is made this [Date], by and between VAN KAMPEN AMERICAN CAPITAL
ASSET MANAGEMENT, INC., a Delaware corporation (the "Adviser") and VAN KAMPEN
AMERICAN CAPITAL ADVISORS, INC., a Delaware corporation (the "Subadviser").
 
WHEREAS, Van Kampen American Capital Tax-Exempt Trust (the "Trust") is
registered under the Investment Company Act of 1940, as amended (the "Act"), as
an open-end, diversified management investment company, consisting of multiple
series of investment portfolios;
 
WHEREAS, the Adviser is registered under the Investment Advisers Act of 1940, as
amended, as an investment adviser and engages in the business of acting as an
investment adviser;
 
WHEREAS, the Subadviser is registered under the Investment Advisers Act of 1940,
as amended, as an investment adviser;
 
WHEREAS, the Agreement and Declaration of Trust authorizes the Trustees of the
Trust to classify or reclassify authorized but unissued shares of the Trust, and
as of the date of this Agreement, the Trust's Trustees have authorized the
issuance of one series of shares representing interests in one investment
portfolio -- the Van Kampen American Capital High Yield Municipal Fund (the
"Fund") (such portfolio and any other portfolios hereafter added to the Trust
being referred to collectively herein as the "Funds");
 
WHEREAS, the Adviser has entered into an Investment Advisory Agreement dated
[Date], with the Trust (the "Investment Advisory Agreement"), pursuant to which
the Adviser shall act as investment adviser with respect to the Fund; and
 
WHEREAS, the securities sought for the investment portfolio of the Fund are sold
in a highly specialized market and the Adviser is desirous to engage a
subadviser in an effort to improve its access to that market and enhance its
ability to acquire investment securities that meet the Fund's investment
objectives;
 
WHEREAS, the Adviser wishes to retain the Subadviser for purposes of rendering
such advisory services to the Adviser in connection with the Fund upon the terms
and conditions hereinafter set forth;
 
NOW, THEREFORE, in consideration of the mutual covenants herein contained and
other good and valuable consideration, the receipt whereof is hereby
acknowledged, the parties hereto agree as follows:
 
                                      B3-1
<PAGE>   63
 
  1. APPOINTMENT OF SUBADVISER. The Adviser hereby appoints the Subadviser to
render investment research and advisory services to the Adviser with respect to
the Fund, under the supervision of the Adviser and subject to the approval and
direction of the Trust's Trustees, and the Subadviser hereby accepts such
appointment, all subject to the terms and conditions contained herein.
 
  2. INVESTMENT ANALYSIS. The duties of the Subadviser shall include:
 
    a. obtaining and evaluating pertinent information about significant
  developments and economic, statistical and financial data, domestic, foreign
  or otherwise, whether affecting the economy generally or the Fund, and whether
  concerning the individual issuers whose securities are included in the Fund or
  the activities in which such issuers engage, or with respect to securities
  which the Subadviser considers desirable for inclusion in the Fund's
  investment portfolio;
 
    b. determining which issuers and securities shall be represented in the
  Fund's investment portfolio and regularly reporting thereon to the Adviser
  and, at the request of the Adviser, to the Trust's Trustees; and
 
    c. formulating and implementing continuing programs for the purchases and
  sales of the securities of such issuers and regularly reporting thereon to the
  Adviser and, at the request of the Adviser, to the Trust's Trustees.
 
  3. CONTROL BY TRUSTEES. Any investment program undertaken by the Subadviser
pursuant to this Agreement, as well as any other activities undertaken by the
Subadviser with respect to the Fund, shall at all times be subject to any
directives of the Trust's Trustees.
 
  4. COMPLIANCE WITH APPLICABLE REQUIREMENTS. In carrying out its obligations
under this Agreement, the Subadviser shall at all times conform to:
 
    a. all applicable provisions of the Act and any rules and regulations
  adopted thereunder;

services rendered hereunder, an annual fee, payable monthly, which for the
initial one-year term of this Agreement shall be paid according to the following
fee schedule: 0.40% of the first $20 million of the Fund's average daily net
assets, 0.25% of the next $30 million of the Fund's average daily net assets and

<PAGE>   64
 
excess over $50 million of the Fund's average daily net assets. The average
daily net assets of the Fund shall be determined by taking the average of the
net assets for each business day during a given calendar month, calculated in
the manner provided in the Trust's Agreement and Declaration of Trust. After the
termination of the initial term of this Agreement, such fee schedule shall be
subject to annual adjustment concurrently with renewal of this Agreement for an
additional one-year term. Each annual renewal shall be deemed to be at the fee
schedule in effect immediately prior to the expiration of the most recent term
unless a new fee schedule is set prior to renewal in writing signed by the
Adviser and the Subadviser, in which case the renewal will be deemed to be at
the fee schedule set forth in such writing.
 
  6. EXPENSES OF THE FUND. All of the ordinary business expenses incurred in the
operations of the Fund and the offering of its shares shall be borne by the Fund
unless specifically provided otherwise in the Investment Advisory Agreement.
 
  7. NON-EXCLUSIVITY. The services of the Subadviser to the Adviser with respect
to the Trust and the Fund are not to be deemed to be exclusive, and the
Subadviser shall be free to render investment advisory and administrative or
other services to others (including other investment companies) and to engage in
other activities. It is understood and agreed that officers or directors of the
Subadviser may serve as officers or directors/trustees of the Adviser or of the
Trust, and that officers or directors/trustees of the Adviser or of the Trust
may serve as officers or directors of the Subadviser to the extent permitted by
law; and that the officers and directors of the Subadviser are not prohibited
from engaging in any other business activity or from rendering services to any
other person, or from serving as partners, officers, directors or trustees of
any other firm or trust, including other investment advisory companies.
 
  8. TERM AND APPROVAL. This Agreement shall have an initial term through May
31, 1999, and may be continued from year to year thereafter, provided that the
continuation of the Agreement is specifically approved at least annually:
 
    a. (i) by the Trust's Trustees or (ii) by the vote of "a majority of the
  outstanding voting securities" of the Fund (as defined in Section 2(a)(42) of
  the Act); and
 
    b. by the affirmative vote of a majority of the trustees who are not parties
  to this Agreement or "interested persons" (as defined in the Act) of a party
  to this Agreement (other than as Trustees of the Trust), by votes cast in
  person at a meeting specifically called for such purpose.
 
  9. TERMINATION. This Agreement may be terminated as to the Fund at any time,
without the payment of any penalty, by vote of the Trust's Trustees or by vote
of a majority of the Fund's outstanding voting securities, or by the Adviser, or
by the Subadviser on sixty (60) days' written notice to the other party and to
the Trust. The notice provided for herein may be waived by either party. This
Agreement shall automatically terminate in the event of its assignment, the term
"assignment" for purposes of this paragraph having the meaning defined in

  10. LIABILITY OF SUBADVISER. In the absence of willful misfeasance, bad faith,
gross negligence or reckless disregard of obligations or duties hereunder on the
part of the Subadviser or any of its officers, directors or employees, the
Subadviser shall not be subject to liability to the Adviser for any act or
omission in the course of, or connected with, rendering services hereunder or
for any losses that may be sustained in the purchase, holding or sale of any
security.
 
  11. NOTICES. Any notices under this Agreement shall be in writing, addressed
and delivered or mailed postage paid to such address as may be designated for

provision of the Act and to interpretations thereof, if any, by the United
States courts or in the absence of any controlling decision of any such court,
by rules, regulations or orders of the Securities and Exchange Commission issued
pursuant to the Act. In addition, where the effect of a requirement of the Act
reflected in any provision of the Agreement is revised by rule, regulation or
order of the Securities and Exchange Commission, such provision shall be deemed
to incorporate the effect of such rule, regulation or order.
 
13. MISCELLANEOUS PROVISIONS
 
  The execution of this Agreement has been authorized by the Trust's Trustees
and by the sole shareholder. This Agreement is executed on behalf of the Trust
