                               PROSPECTUS SUMMARY
- ------------------------------------------------------------------------------
 
THE FUND. Van Kampen American Capital Enterprise Fund (the "Fund") is a
diversified, open-end management investment company organized as a Delaware
business trust.
 
MINIMUM PURCHASE. $500 minimum initial investment for each class of shares and
$25 minimum for each subsequent investment for each class of shares (or less as
described under "Purchase of Shares").
 
   
INVESTMENT OBJECTIVE. The investment objective of the Fund is to seek capital
appreciation by investing in a portfolio of securities consisting principally of
common stocks. There is no assurance that the Fund will achieve its investment
objective. See "Investment Objective and Policies."
    
 
INVESTMENT POLICY. The Fund seeks to achieve its investment objective by
investing principally in common stocks of companies which, in the judgment of
the Adviser, have above average potential for capital appreciation. Because
prices of common stocks and other securities fluctuate, the value of an
investment in the Fund will vary based upon the Fund's investment performance.
The use of options, futures contracts and related options may include additional
risks. See "Investment Practices -- Using Options, Futures Contracts and Options
on Futures Contracts."
 
INVESTMENT RESULTS. The investment results of the Fund are shown in the table of
"Financial Highlights."
 
ALTERNATIVE SALES ARRANGEMENTS. The Fund offers three classes of shares to the
public, each with its own sales charge structure: Class A shares, Class B shares
and Class C shares. Each class has distinct advantages and disadvantages for
different investors, and investors may choose the class of shares that best
suits their circumstances and objectives. Each class of shares represents an
interest in the same portfolio of investments of the Fund. See "Alternative
Sales Arrangements." For information on redeeming shares see "Redemption of
Shares."
 
  Class A Shares. Class A shares are offered at net asset value per share plus a
maximum initial sales charge of 5.75% of the offering price (6.10% of the net
amount invested), reduced on investments of $50,000 or more. Investments of $1
million or more are not subject to any sales charge at the time of purchase, but
a contingent deferred sales charge ("CDSC") of 1.00% may be imposed on
redemptions made within one year of the purchase. Class A shares are subject to

attributable to such class of shares. See "Purchase of Shares -- Class A Shares"
and "Distribution and Service Plans."
 
  Class B Shares. Class B shares are offered at net asset value per share and
are subject to a maximum CDSC of 5.00% on redemptions made within the first year

<PAGE>   6
 
after purchase and declining thereafter to 0.00% after the fifth year. See
"Redemption of Shares." Class B shares are subject to a combined annual
distribution fee and service fee of up to 1.00% of the Fund's average daily net
assets attributable to such class of shares. See "Purchase of Shares -- Class B
Shares" and "Distribution and Service Plans." Class B shares convert
automatically to Class A shares eight years after the end of the calendar month
in which the shareholder's order to purchase was accepted. See "Alternative
Sales Arrangements -- Conversion Feature."
 
  Class C Shares. Class C shares are offered at net asset value per share and
are subject to a CDSC of 1.00% on redemptions made within one year of purchase.
See "Redemption of Shares." Class C shares are subject to a combined annual
distribution fee and service fee of up to 1.00% of the Fund's average daily net
assets attributable to such class of shares. See "Purchase of Shares -- Class C
Shares" and "Distribution and Service Plans."
 
INVESTMENT ADVISER. Van Kampen American Capital Asset Management, Inc. (the
"Adviser") is the Fund's investment adviser.

gains, if any, are distributed at least annually. Such distributions are
automatically reinvested in shares of the Fund at net asset value per share
(without sales charge) unless payment in cash is requested. See "Distributions
from the Fund."

* Based on conversion to Class A shares after eight years.
 
   
  The purpose of the foregoing table is to assist an investor in understanding
the various costs and expenses that an investor in the Fund will bear directly
or indirectly. The "Example" reflects expenses based on the "Annual Fund
Operating Expenses" table as shown above carried out to future years and is
included to provide a means for the investor to compare expense levels of funds
with different fee structures over varying investment periods. To facilitate
such comparison, all funds are required by the SEC to utilize a 5.00% annual
return assumption. The ten year amount with respect to Class B shares of the
Fund reflects the lower aggregate 12b-1 and service fees applicable to such
shares after conversion to Class A shares, Class B shares acquired through the
exchange privilege are subject to the CDSC relating to the Class B shares of the
fund from which the purchase of Class B shares was originally made. Accordingly,
future expenses as projected could be higher than those determined in the above
table if the investor's Class B shares were exchanged from a fund with a higher
CDSC. THE INFORMATION CONTAINED IN THE ABOVE TABLE SHOULD NOT BE CONSIDERED A
REPRESENTATION OF PAST OR FUTURE EXPENSES AND ACTUAL EXPENSES MAY BE GREATER OR
LESS THAN THOSE SHOWN. For a more complete description of such costs and
expenses, see "Purchase of Shares," "Investment Advisory Services," "Redemption
of Shares" and "Distribution and Service Plans."

(d) Class B shares commenced on December 20, 1991, at a net asset value of
    $12.55 per share. At December 31, 1991, there were 763 shares outstanding
    with a per share net asset value of $13.82. The increase in net asset value
    was due principally to unrealized appreciation. There were no dividends or
    distributions paid to shareholders during the period. Other financial
    highlights for the Class B shares for this short period are not meaningful
    and therefore are not presented.

THE FUND
- ------------------------------------------------------------------------------
 
  The Fund is a diversified, open-end management investment company, commonly
known as a mutual fund. A mutual fund provides, for those who have similar
investment goals, a practical and convenient way to invest in a diversified
portfolio of securities by combining their resources in an effort to achieve
such goals.
 
   
  Van Kampen American Capital Asset Management, Inc. (the "Adviser") provides
investment advisory and administrative services to the Fund. The Adviser or its
affiliates also act as investment adviser to other mutual funds distributed by
Van Kampen American Capital Distributors, Inc. (the "Distributor"). To obtain
prospectuses and other information on any of these other funds, please call the
telephone number on the cover page of the Prospectus.
    
 
- ------------------------------------------------------------------------------
INVESTMENT OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------
 
  The Fund's investment objective is to seek capital appreciation by investing
in a portfolio of securities consisting principally of common stocks. The
Adviser will seek to achieve the Fund's investment objective by investing in
securities that it believes have above average potential for capital
appreciation. Any income received on such securities is incidental to the
investment objective of capital appreciation.
 
  The Fund invests principally in growth common stocks. Such securities
generally include those of companies with established records of growth in sales
or earnings, and companies with new products, new services or new processes. The
Fund may also invest in companies in cyclical industries during periods when
their securities appear attractive to the Adviser for capital appreciation. In
addition to common stocks of companies, the Fund may invest in warrants and
preferred stocks, and in other investment companies. The Fund may invest up to
15% of its total assets in securities of issuers located in foreign countries.
 
  The Fund generally holds a portion of its assets in investment grade
short-term debt securities in order to provide liquidity. The Fund also may hold
investment grade corporate or government bonds. The market prices of such bonds
can be expected to vary inversely with changes in prevailing interest rates.
Such investments may be increased when deemed appropriate by the Adviser for
temporary defensive purposes. Short-term investments may include repurchase
agreements with domestic banks or broker-dealers.
 
  The Fund's primary approach is to seek what the Adviser believes to be
unusually attractive growth investments on an individual company basis. The Fund
may invest in securities that have above average price volatility. Just as
prices of common stocks and other securities fluctuate, the value of an
investment in the Fund will vary. The Fund attempts to reduce overall exposure
to risk from declines in
 
                                       10
<PAGE>   13
 
securities prices by spreading its investments over many different companies in
a variety of industries. There is, however, no assurance that the Fund will be
successful in achieving its investment objective.
 
  An investment in the Fund may not be appropriate for all investors. The Fund
is not intended to be a complete investment program, and investors should
consider their long-term investment goals and financial needs when making an
investment decision with respect to the Fund. An investment in the Fund is
intended to be a long-term investment and should not be used as a trading
vehicle.
 
   
  Like other mutual funds, financial and business organizations and individuals
around the world, the Fund could be adversely affected if the computer systems
used by the Fund's Adviser and other service providers do not properly process
and calculate date-related information and data from and after January 1, 2000.
This is commonly known as the "Year 2000 Problem". The Adviser is taking steps
that it believes are reasonably designed to address the Year 2000 Problem with
respect to computer systems that it uses and to obtain reasonable assurances
that comparable steps are being taken by the Fund's other major service
providers. At this time, there can be no assurance that those steps will be
sufficient to avoid any adverse impact to the Fund. In addition, the Year 2000
Problem may adversely affect the issuers of securities in which the Fund may
invest which, in turn, may adversely affect the net asset value of the Fund.
    
 
- ------------------------------------------------------------------------------
INVESTMENT PRACTICES
- ------------------------------------------------------------------------------
 
  REPURCHASE AGREEMENTS. The Fund may enter into repurchase agreements with
domestic banks or broker-dealers in order to earn a return on temporarily
available cash. A repurchase agreement is a short-term investment in which the
purchaser (i.e., the Fund) acquires ownership of a debt security and the seller
agrees to repurchase the obligation at a future time and set price, thereby
determining the yield during the holding period. Repurchase agreements involve
certain risks in the event of default by the other party. The Fund may invest up
to 25% of its assets in repurchase agreements but will not invest in repurchase
agreements maturing in more than seven days if any such investment, together
with any other illiquid securities held by the Fund, would exceed 10% of the
value of its net assets. In the event of a bankruptcy or other default of a
seller of a repurchase agreement, the Fund could experience both delays in
liquidating the underlying securities and loss including: (a) possible decline
in the value of the underlying security during the period while the Fund seeks
to enforce its rights thereto, (b) possible lack of access to income on the
underlying security during this period and (c) expenses of enforcing its rights.
 
  For the purpose of investing in repurchase agreements, the Adviser may
aggregate the cash that certain funds advised or subadvised by the Adviser or
certain of
 
                                       11
<PAGE>   14
 
its affiliates would otherwise invest separately into a joint account. The cash
in the joint account is then invested in repurchase agreements and the funds
that contributed to the joint account share pro rata in the net revenue
generated. The Adviser believes that the joint account produces efficiencies and
economies of scale that may contribute to reduced transaction costs, higher
returns, higher quality investments and greater diversity of investments for the
Fund than would be available to the Fund investing separately. The manner in
which the joint account is managed is subject to conditions set forth in an SEC
exemptive order authorizing this practice, which conditions are designed to
ensure the fair administration of the joint account and to protect the amounts
in that account.
 
  USING OPTIONS, FUTURES CONTRACTS AND RELATED OPTIONS. The Fund expects to
utilize options, futures contracts and options thereon in several different
ways, depending upon the status of the Fund's portfolio and the Adviser's
expectations concerning the securities markets.
 
   
  In times of stable or rising stock prices, the Fund generally seeks to be
fully invested in the equity securities market. Even when the Fund is fully
invested, however, prudent management requires that at least a small portion of
assets be available as cash to honor redemption requests and for other short
term needs. The Fund also may have cash on hand that has not yet been invested.
The portion of the Fund's assets that is invested in cash equivalents does not
fluctuate with stock market prices, so that, in times of rising market prices,
the Fund may underperform the market in proportion to the amount of cash
equivalents in its portfolio. By purchasing stock index futures contracts,
however, the Fund can compensate for the cash portion of its assets and may
obtain performance equivalent to investing 100% of its assets in equity
securities.
    
 
   
  If the Adviser anticipates a market decline, the Fund may seek to reduce its
exposure to the stock market by increasing its cash position. By selling stock
index futures contracts instead of portfolio securities, a similar result may be
achieved to the extent that the performance of the futures contracts correlates
to the performance of the Fund's portfolio securities. Sales of futures
contracts frequently may be accomplished more rapidly and at less cost than the
actual sale of securities. Once the desired hedged position has been effected,
the Fund could then liquidate securities in a more deliberate manner, reducing
its futures position simultaneously to maintain the desired balance, or it could
maintain the hedged position.
    
 
   
  As an alternative to selling futures contracts, the Fund can purchase puts (or
futures puts) to hedge the portfolio's risk in a declining market. Since the
value of a put increases as the underlying security declines below a specified
level, the value is protected against a market decline to the degree the
performance of the put correlates with the performance of the Fund's investment
portfolio. If the market remains stable or advances, the Fund can refrain from
exercising the put and its
    
 
                                       12
<PAGE>   15
 
portfolio will participate in the advance, having incurred only the premium cost
for the put.
 
   
  The Fund is authorized to purchase and sell over-the-counter options ("OTC
Options"). OTC options are purchased from or sold to securities dealers,
financial institutions or other parties ("Counterparties") through direct
bilateral agreement with the Counterparty. The Fund will sell only OTC Options
(other than over the counter currency options) that are subject to a buy-back
provision permitting the Fund to require the Counterparty to sell the option
back to the Fund at a formula price within seven days. The staff of the SEC
currently takes the position that, in general, OTC Options on securities other
than U.S. Government securities purchased by the Fund, and portfolio securities
covering OTC Options sold by the Fund, are illiquid securities subject to the
Fund's limitation on illiquid securities described below.
    
 
   
  POTENTIAL RISKS OF OPTIONS, FUTURES CONTRACTS AND RELATED OPTIONS. In certain
cases, the options and futures markets provide investment or risk management
opportunities that are not available from direct investments in securities. In
addition, some strategies can be performed with greater ease and at lower cost
by utilizing the options and futures markets rather than purchasing or selling
portfolio securities. However, the purchase and sale of options, futures
contracts and related options involve risks different from those involved with
direct investments in underlying securities. While utilization of options,
futures contracts and similar instruments may be advantageous to the Fund, if
the Adviser is not successful in employing such instruments in managing the
Fund's investments, the Fund's performance will be worse than if the Fund did
not make such investments. In addition, the Fund would pay commissions and other
costs in connection with such investments, which may increase the Fund's
expenses and reduce its return.
    
 
   
  In order to prevent leverage in connection with the purchase of futures
contracts or call options by the Fund, an amount of cash or liquid securities
equal to the market value of the obligation under the futures contracts (less
any related margin deposits) will be maintained in a segregated account with the
Custodian. The Fund may not invest more than 10% of its net assets in illiquid
securities including certain OTC Options deemed illiquid and repurchase
agreements which have a maturity of longer than seven days. A more complete
discussion of the potential risks involved in transactions in options, futures
contracts and related options is contained in the Statement of Additional
Information.
    
 
  FOREIGN SECURITIES.  The Fund may invest up to 15% of its total assets in
securities of foreign governments and companies. Such securities may be subject
to foreign government taxes which would reduce the income yield on such
securities. Foreign investments involve certain risks, such as political or
economic instability of the issuer or of the country of issue, the difficulty of
predicting international trade patterns, fluctuating exchange rates and the
possibility of imposition of exchange
                                       13
<PAGE>   16
 
controls. Such securities may also be subject to greater fluctuations in price
than securities of domestic corporations or of the United States Government. In
addition, there may be less publicly available information about a foreign
company than about a domestic company. Foreign companies generally are not
subject to uniform accounting, auditing and financial reporting standards
comparable to those applicable to domestic companies. There is generally less
government regulation of stock exchanges, brokers and listed companies abroad
than in the United States, and, with respect to certain foreign countries, there
is a possibility of expropriation or confiscatory taxation, or diplomatic
developments which could affect investment in those countries. Finally, in the
event of a default on any such foreign debt obligations, it may be more
difficult for the Fund to obtain or to enforce a judgment against the issuers of
such securities.
 
   
  PORTFOLIO TURNOVER. The Fund may purchase and sell securities without regard
to the length of time the security is intended to be or has been held. The rate
may exceed 100%, in any given year, which is higher than that of many other
investment companies. A 100% turnover rate occurs, for example, if all the
Fund's portfolio securities are replaced during one year. High portfolio
activity increases the Fund's transaction costs, including brokerage commissions
and may result in the realization of more short-term capital gains than if the
Fund had lower portfolio turnover. To the extent short-term trading results in
realization of gains on securities held one year or less, shareholders are
subject to taxes at ordinary income rates. The turnover rate will not be a
limiting factor, however, if the Adviser deems portfolio changes appropriate.
The Fund's annual portfolio turnover rate is shown in the table of "Financial
Highlights."
    
 
   
  PORTFOLIO TRANSACTIONS AND BROKERAGE PRACTICES. The Adviser is responsible for
the placement of orders for the purchase and sale of portfolio securities for
the Fund and the negotiation of brokerage commissions on such transactions.
Brokerage firms are selected on the basis of their professional capability for
the type of transaction and the value and quality of execution services on a
continuing basis. The Adviser may place portfolio transactions, to the extent
permitted by law, with brokerage firms affiliated with the Fund, the Adviser or
the Distributor and with Firms participating in the distribution of shares of
the Fund if it reasonably believes that the quality of the execution and the
commission are comparable to that available from other qualified firms. The
Adviser is authorized to pay higher commissions to brokerage firms that provide
it with investment and research information than to firms which do not provide
such services if the Adviser determines that such commissions are reasonable in
relation to the overall services provided. The information received may be used
by the Adviser in managing the assets of other advisory accounts as well as in
the management of the assets of the Fund.
    
 
  INVESTMENT IN INVESTMENT COMPANIES. The Fund may invest in one or more
investment companies advised by the Adviser and its affiliates, including Van
 
                                       14
<PAGE>   17
 
Kampen American Capital Small Capitalization Fund ("Small Cap Fund") and Van
Kampen American Capital Foreign Securities Fund ("Foreign Securities Fund"). The
shares of the Small Cap Fund and Foreign Securities Fund are available for
investment only by certain Van Kampen American Capital funds. The Adviser
believes that the use of the Small Cap Fund and Foreign Securities Fund may,
from time to time, provide the Fund with the most effective exposure to the
performance of the small capitalization sector of the stock market and to
foreign securities while at the same time minimizing costs. The advisers charge
no advisory fees for managing the Small Cap Fund or Foreign Securities Fund, nor
are there any sales load or other charges associated with distribution of its
shares. Other expenses incurred by the Small Cap Fund and Foreign Securities
Fund are borne by them, and thus indirectly by the Van Kampen American Capital
funds that invest in them. With respect to such other expenses, the Adviser
anticipates that the efficiencies resulting from use of the Small Cap Fund or
the Foreign Securities Fund will result in cost savings for the Fund and other
Van Kampen American Capital funds. In large part, these savings are attributable
to the fact that administrative actions that would have to be performed multiple
times if each Van Kampen American Capital fund held its own portfolio of small
capitalization or foreign securities will need to be performed only once. The
Adviser expects that the Small Cap Fund and Foreign Securities Fund will
experience trading costs that will be substantially less than the trading costs
that would be incurred if small capitalization or foreign securities were
purchased separately for the Fund and other Van Kampen American Capital funds.
The Fund's investment in the Small Cap Fund and the Foreign Securities Fund are
subject to the terms and conditions set forth in the SEC exemptive orders
authorizing such investments.
 
  The securities of small and medium sized companies that the Small Cap Fund may
invest in may be subject to more abrupt or erratic market movements than
securities of larger, more established companies or the market averages in
general. In addition, small capitalization companies typically are subject to a
greater degree of change in earnings and business prospects than are larger,
more established companies. In light of these characteristics of small
capitalization companies and their securities, the Small Cap Fund may be subject
to greater investment risk than that assumed through investment in the equity
securities of larger capitalization companies. The securities of foreign issuers
that the Foreign Securities Fund may invest in are subject to certain risks as
described under "Investment Practices--Foreign Securities."
 
  For purposes of reviewing the Fund's portfolio diversification, the Fund will
be deemed to own a pro rata portion of each investment of the Small Cap Fund and
Foreign Securities Fund. For example, if the Fund's investment in the Small Cap
Fund were $10 million, and the Small Cap Fund had 5% of its assets invested in
the electronics industry, the Fund would be considered to have an investment of
$500,000 in the electronics industry.
                                       15

  INVESTMENT RESTRICTIONS. The Fund has adopted certain fundamental investment
restrictions which, like the Fund's investment objective, may not be changed
without approval by a vote of a majority of the outstanding voting shares of the
Fund (as defined in the Investment Company Act of 1940, as amended (the "1940
Act")). One of these restrictions provides that the Fund may not invest more
than 25% of the value of its assets in securities issued by companies in any one
industry, except that the Fund may purchase securities of other investment
companies to the extent permitted by (i) the 1940 Act, as amended from time to
time, (ii) the rules and regulations promulgated by the SEC under the 1940 Act,
as amended from time to time, or (iii) an exemption or other relief from the
provisions of the 1940 Act.

Under the Advisory Agreement, the Fund also reimburses the Adviser for the costs
of the Fund's accounting services, which include maintaining its financial books
and records and calculating its daily net asset value. Operating expenses paid
by the Fund include shareholder service agency fees, service fees, distribution
fees, custodian fees, legal and accounting fees, the costs of reports and
proxies to shareholders, trustees' fees (other than those who are affiliated
persons, as defined in the 1940 Act, of the Adviser, Distributor, ACCESS, Van
Kampen American Capital or Morgan Stanley Dean Witter & Co.), and all other
business expenses not specifically assumed by the Adviser. Advisory (management)
fee and total operating expense ratios are shown under the caption "Annual Fund
Operating Expenses and Example" herein.
    
 
  From time to time the Adviser or the Distributor may voluntarily undertake to
reduce the Fund's expenses by reducing the fees payable to them to the extent
of, or bearing expenses in excess of, such limitations as they may establish.
 
   
  The Adviser may utilize, at its own expense, credit analysis, research and
trading support services provided by its affiliate, Van Kampen American Capital
Investment Advisory Corp. ("Advisory Corp.").
    
 
   
  PERSONAL INVESTMENT POLICIES. The Fund and the Adviser have adopted Codes of
Ethics designed to recognize the fiduciary relationship between the Fund and the
Adviser and its employees. The Codes permit directors, trustees, officers and

- ------------------------------------------------------------------------------
ALTERNATIVE SALES ARRANGEMENTS
- ------------------------------------------------------------------------------
 
  The Alternative Sales Arrangements permits an investor to choose the method of
purchasing shares of the Fund that is most beneficial given the amount of the
purchase and the length of time the investor expects to hold the shares.
 
  CLASS A SHARES. Class A shares are sold at net asset value plus an initial
maximum sales charge of up to 5.75% of the offering price (6.10% of the net
amount invested), reduced on investments of $50,000 or more. Investments of $1
million or more are not subject to any sales charge at the time of purchase, but
a CDSC of 1.00% may be imposed on certain redemptions made within one year of
purchase. Class A shares are subject to an ongoing service fee at an annual rate
of up to 0.25% of the Fund's aggregate average daily net assets attributable to
the Class A shares. Certain purchases of Class A shares qualify for reduced
initial sales charges. See "Purchase of Shares -- Class A Shares."
 
  CLASS B SHARES. Class B shares are sold at net asset value and are subject to
a deferred sales charge if redeemed within five years of purchase. Class B
shares are subject to an ongoing service fee at an annual rate of up to 0.25% of
the Fund's aggregate average daily net assets attributable to the Class B shares
and an ongoing distribution fee at an annual rate of up to 0.75% of the Fund's
aggregate average daily net assets attributable to the Class B shares. Class B
shares enjoy the benefit of permitting all of the investor's dollars to work
from the time the investment is made. The ongoing distribution fee paid by Class
B shares cause such shares to have a higher expense ratio and to pay lower
dividends than those related to Class A shares. Class B shares convert
automatically to Class A shares eight years after the end of the calendar month
in which the shareholder's order to purchase was accepted. See "Purchase of
Shares -- Class B Shares."
 
  CLASS C SHARES. Class C shares are sold at net asset value and are subject to
a deferred sales charge if redeemed within one year of purchase. Class C shares
are subject to an ongoing service fee at an annual rate of up to 0.25% of the
Fund's aggregate average daily net assets attributable to the Class C shares and
an ongoing distribution fee at an annual rate of up to 0.75% of the Fund's
aggregate average daily net assets attributable to the Class C shares. Class C
shares enjoy the benefit of permitting all of the investor's dollars to work
from the time the investment is
 
                                       18
<PAGE>   21
 
made. The ongoing distribution fee paid by Class C shares cause such shares to
have a higher expense ratio and to pay lower dividends than those related to
Class A shares. See "Purchase of Shares -- Class C Shares."
 
   
  CONVERSION FEATURE. Class B shares purchased on or after June 1, 1996, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A shares eight years after the end of the calendar month in which the
shares were purchased. Class B shares purchased before June 1, 1996, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A shares six years after the end of the calendar month in which the shares
were purchased. Class C shares purchased before January 1, 1997, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A shares ten years after the end of the calendar month in which such
shares were purchased. Such conversion will be on the basis of the relative net
asset values per share, without the imposition of any sales load, fee or other
charge. The conversion schedule applicable to a share acquired through the
exchange privilege is determined by reference to the Participating Fund (defined
below) from which such share was originally purchased.
    
 
  The conversion of such shares to Class A shares is subject to the continuing
availability of an opinion of counsel to the effect that (i) the assessment of
the higher distribution fee and transfer agency costs with respect to such
shares does not result in the Fund's dividends or distributions constituting
"preferential dividends" under the Internal Revenue Code of 1986, as amended
(the "Code") and (ii) the conversion of shares does not constitute a taxable
event under federal income tax law. The conversion may be suspended if such an
opinion is no longer available and such shares might continue to be subject to
the higher aggregate fees applicable to such shares for an indefinite period.
 
  FACTORS FOR CONSIDERATION. In deciding which class of shares to purchase,
investors should take into consideration their investment goals, present and
anticipated purchase amounts, time horizons and temperaments. Investors should
consider whether, during the anticipated life of their investment in the Fund,
the higher aggregate fees and CDSC on Class B shares and Class C shares would be
less than the initial sales charge on Class A shares purchased at the same time,
and to what extent such differential would be offset by the higher dividends per
share on Class A shares. To assist investors in making this determination, the
table under the caption "Annual Fund Operating Expenses and Example" sets forth
examples of the charges applicable to each class of shares. In this regard,
Class A shares may be more beneficial to the investor who qualifies for reduced
initial sales charges or purchases at net asset value. It is presently the
policy of the Distributor not to accept any order of $500,000 or more for Class
B shares or any order of $1 million or more for Class C shares as it ordinarily
would be more beneficial for such an investor to purchase Class A shares.
 
                                       19
<PAGE>   22
 
   
  Class A shares are not subject to an ongoing distribution fee and,
accordingly, receive correspondingly higher dividends per share. However,
because initial sales charges are deducted at the time of purchase for accounts
under $1 million, investors in Class A shares do not have all their funds
invested initially and, therefore initially own fewer shares. Other investors
might determine that it is more advantageous to purchase either Class B shares
or Class C shares and have all their funds invested initially, although
remaining subject to a CDSC. Ongoing distribution fees on Class B shares and
Class C shares may be offset to the extent of the additional funds originally
invested and any return realized on those funds. However, there can be no
assurance as to the return, if any, which will be realized on such additional
funds. For investments held for ten years or more, the relative value upon
liquidation of the three classes tends to favor Class A shares or Class B
shares, rather than Class C shares.
    
 
  Class A shares may be appropriate for investors who prefer to pay the sales
charge up front, want to take advantage of the reduced sales charges available
on larger investments, wish to maximize their current income from the start,
prefer not to pay redemption charges or have a longer-term investment horizon.
Class B shares may be appropriate for investors who wish to avoid a front-end
sales charge, put 100% of their investment dollars to work immediately or have a
longer-term investment horizon. Class C shares may be appropriate for investors
who wish to avoid a front-end sales charge, put 100% of their investment dollars
to work immediately, have a shorter-term investment horizon or desire a short
CDSC schedule.
 
  The distribution expenses incurred by the Distributor in connection with the
sale of the shares will be reimbursed, in the case of Class A shares, from the
proceeds of the initial sales charge and, in the case of Class B shares and
Class C shares, from the proceeds of the ongoing distribution fee and any CDSC
incurred upon redemption within five years or one year, respectively, of
purchase. Sales personnel of broker-dealers distributing the Fund's shares and
other persons entitled to receive compensation for selling such shares may
receive differing compensation for selling such shares. INVESTORS SHOULD
UNDERSTAND THAT THE PURPOSE AND FUNCTION OF THE CDSC AND ONGOING DISTRIBUTION
FEE WITH RESPECT TO THE CLASS B SHARES AND CLASS C SHARES ARE THE SAME AS THOSE
OF THE INITIAL SALES CHARGE WITH RESPECT TO CLASS A SHARES. See "Distribution
and Service Plans."
 
  GENERAL. Dividends paid by the Fund with respect to Class A shares, Class B
shares and Class C shares will be calculated in the same manner at the same time
on the same day, except that the higher distribution fees and transfer agency
costs relating to Class B shares or Class C shares will be borne by the
respective class. See "Distributions from the Fund." Shares of the Fund may be
exchanged, subject to certain limitations, for shares of the same class of
certain other mutual funds advised by the Adviser and its affiliates and
distributed by the Distributor. See "Shareholder Services -- Exchange
Privilege."

PURCHASE OF SHARES
- ------------------------------------------------------------------------------
 
GENERAL
 
  The Fund offers three classes of shares to the public on a continuous basis
through the Distributor as principal underwriter, which is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181. Shares also are offered
through members of the National Association of Securities Dealers, Inc. ("NASD")
who are acting as securities dealers ("dealers") and NASD members or eligible
non-NASD members who are acting as brokers or agents for investors ("brokers").
The term "dealers" and "brokers" are sometimes referred to herein as "authorized
dealers."
 
  Initial investments must be at least $500 for each class of shares, and
subsequent investments must be at least $25 for each class of shares. Both
minimums may be waived by the Distributor for plans involving periodic
investments. Shares of the Fund may be sold in foreign countries where
permissible. The Fund and the Distributor reserve the right to refuse any order
for the purchase of shares. The Fund also reserves the right to suspend the sale
of the Fund's shares in response to conditions in the securities markets or for
other reasons.
 
  Shares may be purchased on any business day through authorized dealers. Shares
also may be purchased by completing the application accompanying this Prospectus
and forwarding the application, through the authorized dealer, to the
shareholder service agent, ACCESS Investor Services, Inc. ("ACCESS"), a
wholly-owned subsidiary of Van Kampen American Capital. When purchasing shares
of the Fund, investors must specify whether the purchase is for Class A shares,
Class B shares or Class C shares.
 
  Shares are offered at the next determined net asset value per share, plus a
front-end or deferred sales charge depending on the class of shares chosen by
the investor, as shown in the tables herein. Net asset value per share for each
class is determined once daily as of the close of trading on the New York Stock
Exchange (the "Exchange") (currently 4:00 p.m., New York time) each day the
Exchange is open. Net asset value per share for each class is determined by
dividing the value of the Fund's securities, cash and other assets (including
accrued interest) attributable to such class less all liabilities (including
accrued expenses) attributable to such class by the total number of shares of
the class outstanding.
 
   
  Securities, including options, listed or traded on a national securities
exchange are valued at the last sale price. Unlisted securities and listed
securities for which the last sale price is not available are valued at the mean
between the last reported bid and asked price. Securities for which market
quotations are not readily available and other assets are valued at fair value
as determined in good faith by the Adviser based on procedures approved by the
Board of Trustees of the Fund. Short-term
    
 
                                       21
<PAGE>   24
 
securities are valued in the manner described in the Statement of Additional
Information.
 
  Generally, the net asset values per share of the Class A shares, Class B
shares and Class C shares are expected to be substantially the same. Under
certain circumstances, however, the per share net asset values of the Class A
shares, Class B shares and Class C shares may differ from one another,
reflecting the daily expense accruals of the higher distribution fees and
transfer agency costs applicable with respect to the Class B shares and Class C
shares and the differential in the dividends paid on the classes of shares. The
price paid for shares purchased is based on the next calculation of net asset
value (plus sales charges, where applicable) after an order is received by an
authorized dealer provided such order is transmitted to the Distributor prior to
the Distributor's close of business on such day. Orders received by authorized
dealers after the close of the Exchange are priced based on the next close
provided they are received by the Distributor prior to the Distributor's close
of business on such day. It is the responsibility of authorized dealers to
transmit orders received by them to the Distributor so they will be received
prior to such time. Orders of less than $500 are mailed by the authorized dealer
and processed at the offering price next calculated after acceptance by ACCESS.
 
   
  Each class of shares represents an interest in the same portfolio of
investments of the Fund and, has the same rights, except that (i) Class B shares
and Class C shares bear the expenses of the deferred sales arrangement and any
expenses (including the higher distribution fee and transfer agency costs)
resulting from such sales arrangement, (ii) generally, each class has exclusive
voting rights with respect to approvals of the Rule 12b-1 distribution plan
pursuant to which its distribution fee or service fee is paid, (iii) each class
of shares has different exchange privileges, (iv) certain shares are subject to
a conversion feature and (v) certain classes of shares have different
shareholder service options available. The net income attributable to Class B
shares and Class C shares and the dividends payable on Class B shares and Class
C shares will be reduced by the amount of the distribution fee and other
expenses associated with such shares. Sales personnel of authorized dealers
distributing the Fund's shares and other persons entitled to receive
compensation for selling such shares may receive differing compensation for
selling Class A shares, Class B shares or Class C shares.
    
 
   
  The Distributor may from time to time implement programs under which an
authorized dealer's sales force may be eligible to win nominal awards for
certain sales efforts or under which the Distributor will reallow to any
authorized dealer that sponsors sales contests or recognition programs
conforming to criteria established by the Distributor, or participates in sales
programs sponsored by the Distributor, an amount not exceeding the total
applicable sales charges on the sales generated by the authorized dealer at the
public offering price during such programs. Other programs provide, among other
things and subject to certain
    
 
                                       22
<PAGE>   25
 
   
conditions, for certain favorable distribution arrangements for shares of the
Fund. Also, the Distributor in its discretion may from time to time, pursuant to
objective criteria established by the Distributor, pay fees to, and sponsor
business seminars for, qualifying authorized dealers for certain services or
activities which are primarily intended to result in sales of shares of the
Fund. Fees may include payment for travel expenses, including lodging, incurred
in connection with trips taken by invited registered representatives and members
of their families to locations within or outside of the United States for
meetings or seminars of a business nature. In some instances, additional
compensation or promotional incentives may be offered to brokers, dealers or
financial intermediaries that have sold or may sell significant amounts of
shares during specific periods of time. The Distributor may provide additional
compensation to Edward D. Jones & Co. or an affiliate thereof based on a
combination of its sales of shares and increases in assets under management. All
of the foregoing payments are made by the Distributor out of its own assets.
Such fees paid for such services and activities with respect to the Fund will
not exceed in the aggregate 1.25% of the average total daily net assets of the
Fund on an annual basis. These programs will not change the price an investor
will pay for shares or the amount that the Fund will receive from such sale.
    
 
CLASS A SHARES
 
   
  The public offering price of Class A shares is the net asset value plus a
sales charge, as set forth below.

* No sales charge is payable at the time of purchase on investments of $1
  million or more, although for such investments the Fund imposes a CDSC
  of 1.00% on redemptions made within one year of the purchase. A
  commission will be paid to authorized dealers who initiate and are
  responsible for purchases of $1 million or more as follows: 1.00% on
  sales to $2 million, plus 0.80% on the next $1 million and 0.50% on the
  excess over $3 million.

  In addition to the reallowances from the applicable public offering price
described herein, the Distributor may, from time to time, pay or allow
additional reallowances or promotional incentives, in the form of cash or other
compensation, to authorized dealers that sell shares of the Fund. Authorized
dealers which are reallowed all or substantially all of the sales charges may be
deemed to be underwriters for purposes of the Securities Act of 1933, as
amended.
 
   
  The Distributor may also pay financial institutions (which may include banks)
and other industry professionals that provide services to facilitate
transactions in shares of the Fund for their clients a transaction fee up to the
level of the reallowance allowable to authorized dealers described herein. Such
financial institutions, other industry professionals and authorized dealers are
hereinafter referred to as "Service Organizations." Banks are currently
prohibited from providing certain underwriting or distribution services. If
banking firms were prohibited from acting in any capacity or providing any of
the described services, the Distributor would consider what action, if any,
would be appropriate. The Distributor does not believe that termination of a
relationship with a bank would result in any material adverse consequences to
the Fund. State securities laws regarding registration of banks and other
financial institutions may differ from the interpretations of federal law
expressed herein and banks and other financial institutions may be required to
register as dealers pursuant to certain state laws.
    
 
QUANTITY DISCOUNTS
 
  Investors purchasing Class A shares may, under certain circumstances, be
entitled to pay reduced sales charges. The circumstances under which such
investors may pay reduced sales charges are described below.
 
   
  Investors or their authorized dealers must notify the Fund at the time of the
purchase order whenever a quantity discount is applicable to purchases. Upon
such notification, an investor will receive the lowest applicable sales charge.
Quantity discounts may be modified or terminated at any time. For more
information about quantity discounts, investors should contact their authorized
dealer or the Distributor.
    
 
   
  A person eligible for a reduced sales charge includes an individual, his or
her spouse and children under 21 years of age and any corporation, partnership
or sole proprietorship which is 100% owned, either alone or in combination, by
any of the foregoing; a trustee or other fiduciary purchasing for a single trust
or for a single fiduciary account, or a "company" as defined in Section 2(a)(8)
of the 1940 Act.
    
 
   
  As used herein, "Participating Funds" refers to certain open-end investment
companies advised by the Adviser or Advisory Corp. and distributed by the
Distributor as determined from time to time by the Fund's Board of Trustees.
    
 
                                       24
<PAGE>   27
 
  Volume Discounts. The size of investment shown in the preceding sales charge
table applies to the total dollar amount being invested by any person in shares
of the Fund or in any combination of shares of the Fund and shares of other
Participating Funds, although other Participating Funds may have different sales
charges.
 
  Cumulative Purchase Discount. The size of investment shown in the preceding
sales charge table may also be determined by combining the amount being invested
in shares of the Participating Funds plus the current offering price of all
shares of the Participating Funds which have been previously purchased and are
still owned.
 
   
  Letter of Intent. A Letter of Intent provides an opportunity for an investor
to obtain a reduced sales charge by aggregating the investments over a
thirteen-month period to determine the sales charge as outlined in the preceding
sales charge table. The size of investment shown in the preceding sales charge
table also includes purchases of shares of the Participating Funds over a
thirteen-month period based on the total amount of intended purchases plus the
value of all shares of the Participating Funds previously purchased and still
owned. An investor may elect to compute the thirteen-month period starting up to
90 days before the date of execution of a Letter of Intent. Each investment made
during the period receives the reduced sales charge applicable to the total
amount of the investment goal. If the goal is not achieved within the period,
the investor must pay the difference between the sales charges applicable to the
purchases made and the sales charges previously paid. The initial purchase must
be for an amount equal to at least 5% of the minimum total purchased amount of
the level selected. If trades not initially made under a Letter of Intent
subsequently qualify for a lower sales charge through the 90-day back-dating
provisions, an adjustment will be made at the expiration of the Letter of Intent
to give effect to the lower charge. Such adjustments in sales charge will be
used to purchase additional shares for the shareholder at the applicable
discount category. Additional information is contained in the application form
accompanying this Prospectus.
    
 
OTHER PURCHASE PROGRAMS
 
  Purchasers of Class A shares may be entitled to reduced initial sales charges
in connection with unit investment trust reinvestment programs and purchases by
registered representatives of selling firms or purchases by persons affiliated
with the Fund or the Distributor. The Fund reserves the right to modify or
terminate these arrangements at any time.
 
  Unit Investment Trust Reinvestment Programs. The Fund permits unitholders of
unit investment trusts to reinvest distributions from such trusts in Class A
shares of the Fund at net asset value with no minimum initial or subsequent
investment requirement if the administrator of an investor's unit investment
trust program meets certain uniform criteria relating to cost savings by the
Fund and the Distributor. The total sales charge for all other investments made
from unit trust
                                       25
<PAGE>   28
 
distributions will be 1.00% of the offering price (1.01% of net asset value). Of
this amount, the Distributor will pay to the authorized dealer, if any, through
which such participation in the qualifying program was initiated 0.50% of the
offering price as a dealer concession or agency commission. Persons desiring
more information with respect to this program, including the applicable terms
and conditions thereof, should contact their authorized dealer or the
Distributor.
 
  The administrator of such a unit investment trust must have an agreement with
the Distributor pursuant to which the administrator will (1) submit a single
bulk order and make payment with a single remittance for all investments in the
Fund during each distribution period by all investors who choose to invest in
the Fund through the program and (2) provide ACCESS with appropriate backup data
for each participating investor in a computerized format fully compatible with
ACCESS' processing system.
 
  As further requirements for obtaining these special benefits, the Fund also
requires that all dividends and other distributions by the Fund be reinvested in
additional shares without any systematic withdrawal program. There will be no
minimum for reinvestments from unit investment trusts. The Fund will send
account activity statements to such participants on a monthly basis only, even
if their investments are made more frequently. The Fund reserves the right to
modify or terminate this program at any time.
 
  NAV Purchase Options. Class A shares of the Fund may be purchased at net asset
value, upon written assurance that the purchase is made for investment purposes
and that the shares will not be resold except through redemption by the Fund,
by:
 
   
  (1) Current or retired trustees or directors of funds advised by the Adviser
      or Advisory Corp. and such persons' families and their beneficial
      accounts.
    
 
  (2) Current or retired directors, officers and employees of Morgan Stanley
      Group Inc. and any of its subsidiaries, employees of an investment
      subadviser to any fund described in (1) above or an affiliate of such
      subadviser, and such persons' families and their beneficial accounts.
 
   
  (3) Directors, officers, employees and, when permitted, registered
      representatives of financial institutions that have a selling group
      agreement with the Distributor and their spouses and children under 21
      years of age when purchasing for any accounts they beneficially own, or,
      in the case of any such financial institution, when purchasing for
      retirement plans for such institution's employees, provided that such
      procedures are otherwise permitted by such institutions.
    
 
   
  (4) Registered investment advisers, who charge a fee for their services, trust
      companies and bank trust departments investing on their own behalf or on
      behalf of their clients. The Distributor may pay authorized dealers
      through
    
 
                                       26
<PAGE>   29
 
   
      which purchases are made an amount up to 0.50% of the amount invested over
      a twelve-month period following such transaction.
    
 
   
  (5) Trustees and other fiduciaries purchasing shares for retirement plans
      which invest in multiple fund families through broker-dealer retirement
      plan alliance programs that have entered into agreements with the
      Distributor and which are subject to certain minimum size and operational
      requirements. Trustees and other fiduciaries should refer to the Statement
      of Additional Information for further detail with respect to such alliance
      programs.
    
 
   
  (6) Beneficial owners of shares of Participating Funds held by a retirement
      plan or held in a tax-advantaged retirement account who purchases shares
      of the Fund with proceeds from distributions from such a plan or
      retirement account other than distributions taken to correct excess
      contribution.
    
 
   
  (7) Accounts as to which a bank or broker-dealer charges an account management
      fee ("wrap accounts"), provided the bank or broker-dealer has a separate
      agreement with the Distributor.
    
 
   
  (8) Trusts created under pension, profit sharing or other employee benefit
      plans qualified under Section 401(a) of the Code, or custodial accounts
      held by a bank created pursuant to Section 403(b) of the Code and
      sponsored by non-profit organizations defined under Section 501(c)(3) of
      the Code and assets held by an employer or trustee in connection with an
      eligible deferred compensation plan under Section 457 of the Code. Such
      plans will qualify for purchases at net asset value provided, for plans
      initially establishing accounts with the Distributor in the Participating
      Funds after February 1, 1997, that (1) the initial amount invested in the
      Participating Funds is at least $500,000 or (2) such shares are purchased
      by an employer sponsored plan with more than 100 eligible employees. Such
      plans that have been established with a Participating Fund or have
      received proposals from the Distributor prior to February 1, 1997 based on
      net asset value purchase privileges previously in effect will be qualified
      to purchase shares of the Participating Funds at net asset value for
      accounts established on or before May 1, 1997. Section 403(b) and similar
      accounts for which Van Kampen American Capital Trust Company served as
      custodian will not be eligible for net asset value purchases based on the
      aggregate investment made by the plan or the number of eligible employees,
      except under certain uniform criteria established by the Distributor from
      time to time. Prior to February 1, 1997, a commission will be paid to
      authorized dealers who initiate and are responsible for such purchases
      within a rolling twelve-month period as follows: 1.00% on sales to $5
      million, plus 0.50% on the next $5 million, plus 0.25% on the excess over
      $10 million. For purchases on February 1, 1997 and thereafter, a
      commission will be paid as follows: 1.00% on sales to $2 million, plus
      0.80% on the next $1 million, plus 0.50% on the next $47 million and 0.25%
      on the excess over $50 million.

<PAGE>   30
 
   
  (9) Individuals who are members of a "qualified group". For this purpose, a
      qualified group is one which (i) has been in existence for more than six
      months, (ii) has a purpose other than to acquire shares of the Fund or
      similar investments, (iii) has given and continues to give its endorsement
      or authorization, on behalf of the group, for purchase of shares of the
      Fund and Participating Funds, (iv) has a membership that the authorized
      dealer can certify as to the group's members and (v) satisfies other
      uniform criteria established by the Distributor for the purpose of
      realizing economies of scale in distributing such shares. A qualified
      group does not include one whose sole organizational nexus, for example,
      is that its participants are credit card holders of the same institution,
      policy holders of an insurance company, customers of a bank or
      broker-dealer, clients of an investment adviser or other similar groups.
      Shares purchased in each group's participants account in connection with
      this privilege will be subject to a CDSC of 1.00% in the event of
      redemption within one year of purchase, and a commission will be paid to
      authorized dealers who initiate and are responsible for such sales to each
      individual as follows: 1.00% on sales to $2 million, plus 0.80% on the
      next $1 million and 0.50% on the excess over $3 million.
    
 
  The term "families" includes a person's spouse, children under 21 years of age
and grandchildren, parents, and a person's spouse's parents.
 
  Purchase orders made pursuant to clause (4) may be placed either through
authorized dealers as described above or directly with ACCESS by the investment
adviser, trust company or bank trust department, provided that ACCESS receives
federal funds for the purchase by the close of business on the next business day
following acceptance of the order. An authorized dealer may charge a transaction
fee for placing an order to purchase shares pursuant to this provision or for
placing a redemption order with respect to such shares. Authorized dealers will
be paid a service fee as described herein under "Distribution and Service Plans"
on purchases made as described in (3) through (9) above. The Fund may terminate,
or amend the terms of, offering shares of the Fund at net asset value to such
groups at any time.
 
CLASS B SHARES
 
  Class B shares are offered at net asset value. Class B shares which are
redeemed within five years of purchase are subject to a CDSC at the rates set
forth in the following table charged as a percentage of the dollar amount
subject thereto. The charge is assessed on an amount equal to the lesser of the
then current market value or the cost of the shares being redeemed. Accordingly,
no sales charge is imposed on increases in net asset value above the initial
purchase price. In addition, no charge is assessed on shares derived from
reinvestment of dividends or capital gains
 
                                       28
<PAGE>   31
 
distributions. It is presently the policy of the Distributor not to accept any
order for Class B shares in an amount of $500,000 or more because it ordinarily
will be more advantageous for an investor making such an investment to purchase
Class A shares.
 
  The amount of the CDSC, if any, varies depending on the number of years from
the time of payment for the purchase of Class B shares until the time of
redemption of such shares. Solely for purposes of determining the number of
years from the time of any payment for the purchases of shares, all payments
during a month are aggregated and deemed to have been made on the last day of
the month.

  In determining whether a CDSC is applicable to a redemption, it is assumed
that the redemption is first of any shares in the shareholder's Fund account
that are not subject to a CDSC, second of shares held for over five years and
third of shares held longest during the five-year period.
    
 
  To provide an example, assume an investor purchased 100 shares at $10 per
share (at a cost of $1,000) and in the second year after purchase, the net asset
value per share is $12 and, during such time, the investor has acquired 10
additional shares upon dividend reinvestment. If at such time the investor makes
his or her first redemption of 50 shares (proceeds of $600), 10 shares will not
be subject to charge because of dividend reinvestment. With respect to the
remaining 40 shares, the charge is applied only to the original cost of $10 per
share and not to the increase in net asset value of $2 per share. Therefore,
$400 of the $600 redemption proceeds is subject to a deferred sales charge at a
rate of 4.00% (the applicable rate in the second year after purchase).
 
  A commission or transaction fee of 4.00% of the purchase amount will be paid
to authorized dealers at the time of purchase. Additionally, the Distributor
may, from time to time, pay additional promotional incentives in the form of
cash or other compensation to authorized dealers that sell Class B shares of the
Fund.

CLASS C SHARES
 
  Class C shares are offered at net asset value. Class C shares which are
redeemed within the first year of purchase are subject to a CDSC of 1.00%. The
charge is assessed on an amount equal to the lower of the then current market
value or the cost of the shares being redeemed. Accordingly, no sales charge is
imposed on increases in net asset value above the initial purchase price. In
addition, no charge is assessed on shares derived from reinvestment of dividends
or capital gains distributions. It is presently the policy of the Distributor
not to accept any order for Class C shares in an amount of $1 million or more
because it ordinarily will be more advantageous for an investor making such an
investment to buy Class A shares.
 
   
  In determining whether a CDSC is applicable to a redemption, it is assumed
that the redemption is first of any shares in the shareholder's Fund account
that are not subject to a CDSC and second of shares held for more than one year.
    
 
   
  A commission or transaction fee of up to 1.00% of the purchase amount will
generally be paid to authorized dealers at the time of purchase. Authorized
dealers also will be paid ongoing commissions and transaction fees of up to
0.75% of the average daily net assets of the Fund's Class C shares annually
commencing in the second year after purchase. Additionally, the Distributor may,
from time to time, pay additional promotional incentives in the form of cash or
other compensation to authorized dealers that sell Class C shares of the Fund.
    
 
WAIVER OF CONTINGENT DEFERRED SALES CHARGE
 
   
  The CDSC is waived on redemptions of Class B shares and Class C shares (i)
following the death or disability (as defined in the Code) of a shareholder,
(ii) in connection with required minimum distributions from an IRA or other
retirement plan, (iii) pursuant to the Fund's systematic withdrawal plan but
limited to 12% annually of the initial value of the account, (iv) in
circumstances under which no commission or transaction fee is paid to authorized
dealers at the time of purchase of such shares and (v) effected pursuant to the
right of the Fund to liquidate a shareholder's account as described herein under
"Redemption of Shares." The CDSC also is waived on redemptions of Class C shares
as it relates to the reinvestment of redemption proceeds in shares of the same
class of the Fund within 180 days after redemption. See the Statement of
Additional Information for further discussion of waiver provisions.

SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------
 
  The Fund offers a number of shareholder services designed to facilitate
investment in its shares at little or no extra cost to the investor. The
following is a description of such services.
 
   
  INVESTMENT ACCOUNT. Each shareholder has an investment account under which the
investor's shares of the Fund are held by ACCESS, the Fund's transfer agent.
ACCESS performs bookkeeping, data processing and administration services related
to the maintenance of shareholder accounts. Except as described in this
Prospectus, after each share transaction in an account, the shareholder receives
a statement showing the activity in the account. Each shareholder who has an
account in certain of the Participating Funds will receive statements quarterly
from ACCESS showing any reinvestments of dividends and capital gains
distributions and any other activity in the account since the preceding
statement. Such shareholders also will receive separate confirmations for each
purchase or sale transaction other than reinvestment of dividends and capital
gains distributions and systematic purchases or redemptions. Additions to an
investment account may be made at any time by purchasing shares through
authorized dealers or by mailing a check directly to ACCESS.
    
 
   
  SHARE CERTIFICATES. Generally, the Fund will not issue share certificates.
However, upon written or telephone request to the Fund, a share certificate will
be issued representing shares (with the exception of fractional shares) of the
Fund. A shareholder will be required to surrender such certificates upon
redemption thereof. In addition, if such certificates are lost the shareholder
must write to Van Kampen American Capital Funds, c/o ACCESS, P.O. Box 418256,
Kansas City, MO 64141-9256, requesting an "affidavit of loss" and obtain a
Surety Bond in a form acceptable to ACCESS. On the date the letter is received,
ACCESS will calculate a fee for replacing the lost certificates equal to no more
than 2.00% of the net asset value of the issued shares, and bill the party to
whom the replacement certificate was mailed.
    
 
   
  REINVESTMENT PLAN. A convenient way for investors to accumulate additional
shares is by accepting dividends and capital gains distributions in shares of
the Fund. Such shares are acquired at net asset value per share (without sales
charge) on the record date. Unless the shareholder instructs otherwise, the
reinvestment plan is automatic. This instruction may be made by telephone by
calling (800) 341-2911 ((800) 421-2833 for the hearing impaired) or in writing
to ACCESS. The investor may, on the initial application or prior to any
declaration, instruct that dividends be paid in cash and capital gains
distributions be reinvested at net asset value, or that both dividends and
capital gains distributions be paid in cash.
    
 
                                       31
<PAGE>   34
 
   
  AUTOMATIC INVESTMENT PLAN. An automatic investment plan is available under
which a shareholder can authorize ACCESS to debit a bank account on a regular
basis to invest predetermined amounts in the Fund. Additional information is
available from the Distributor or authorized dealers.
    
 
   
  RETIREMENT PLANS. Eligible investors may establish individual retirement
accounts ("IRAs"); SEP; 401(k) plans; Section 403(b)(7) plans in the case of
employees of public school systems and certain non-profit organizations; or
other pension or profit sharing plan. Documents and forms containing detailed
information regarding these plans are available from the Distributor. Van Kampen
American Capital Trust Company serves as custodian under the IRA, 403(b)(7) and
Keogh plans. Details regarding fees, as well as full plan administration for
profit sharing, pension and 401(k) plans, are available from the Distributor.
    
 
   
  AUTOMATED CLEARING HOUSE ("ACH") DEPOSITS.  Holders of Class A shares can use
ACH to have redemption proceeds deposited electronically into their bank
accounts. Redemptions transferred to a bank account via the ACH plan are
available to be credited to the account on the second business day following
normal payment. In order to utilize this option, the shareholder's bank must be
a member of ACH. In addition, the shareholder must fill out the appropriate
section of the account application. The shareholder must also include a voided
check or deposit slip from the bank account into which redemptions are to be
deposited together with the completed application. Once ACCESS has received the
application and the voided check or deposit slip, such shareholder's designated
bank account, following any redemption, will be credited with the proceeds of
such redemption. Once enrolled in the ACH plan, a shareholder may terminate
participation at any time by writing ACCESS.
    
 
   
  DIVIDEND DIVERSIFICATION. A shareholder may, upon written request or by
completing the appropriate section of the application form accompanying this
Prospectus or by calling (800 341-2911 ((800) 421-2833 for the hearing
impaired), elect to have all dividends and other distributions paid on a class
of shares of the Fund invested into shares of the same class of any
Participating Fund so long as the investor has a pre-existing account for such
class of shares of the other fund. Both accounts must be of the same type,
either non-retirement or retirement. If the accounts are retirement accounts,
they must both be for the same class and of the same type of retirement plan
(e.g., IRA, 403(b)(7), 401(k), Keogh) and the benefit of the same individual. If
a qualified, pre-existing account does not exist, the shareholder must establish
a new account subject to minimum investment and other requirements of the fund
into which distributions would be invested. Distributions are invested into the
selected fund at its net asset value as of the payable date of the distribution.
    
 
   
  EXCHANGE PRIVILEGE. Shares of the Fund may be exchanged for shares of the same
class of any Participating Fund based on the next computed net asset values of
    
                                       32
<PAGE>   35
 
   
each fund after requesting the exchange without any sales charge, subject to
certain limitations. Shares of the Fund may be exchanged for shares of any
Participating Fund only if shares of that Participating Fund are available for
sale; however, during periods of suspension of sales, shares of a Participating
Fund may be available for sale only to existing shareholders of the
Participating Fund. Shareholders seeking an exchange into a Participating Fund
should obtain and read the current prospectus for such fund.
    
 
   
  To be eligible for exchange, shares of the Fund must have been registered in
the shareholder's name for at least 30 days. Shares of the Fund registered in a
shareholder's name for less than 30 days may only be exchanged upon receipt of
prior approval of the Adviser. It is the policy of the Adviser, under normal
circumstances, not to approve such requests.
    
 
   
  When Class B shares and Class C shares are exchanged among Participating
Funds, the holding period for purposes of computing the CDSC is based upon the
date of the initial purchase of such shares from a Participating Fund. If such
Class B or Class C shares are redeemed and not exchanged for shares of another
Participating Fund, such Class B or Class C shares are subject to the CDSC
schedule proposed by the Participating Fund from which such shares were
originally purchased.
    
 
   
  Exchanges of shares are sales and may result in a gain or loss for federal
income tax purposes. If the shares exchanged have been held for less than 91
days, the sales charge paid on such shares is carried over and included in the
tax basis of the shares acquired.
    
 
   
  A shareholder wishing to make an exchange may do so by sending a written
request to ACCESS or by contacting the telephone transaction line at (800)
421-5684. A shareholder automatically has telephone exchange privileges unless
otherwise designated in the application form accompanying this Prospectus. Van
Kampen American Capital and its subsidiaries, including ACCESS (collectively,
"VKAC"), and the Fund employ procedures considered by them to be reasonable to
confirm that instructions communicated by telephone are genuine. Such procedures
include requiring certain personal identification information prior to acting
upon telephone instructions, tape recording telephone communications, and
providing written confirmation of instructions communicated by telephone. If
reasonable procedures are employed, neither VKAC nor the Fund will be liable for
following telephone instructions which it reasonably believes to be genuine.
VKAC and the Fund may be liable for any losses due to unauthorized or fraudulent
instructions if reasonable procedures are not followed. If the exchanging
shareholder does not have an account in the fund whose shares are being
acquired, a new account will be established with the same registration, dividend
and capital gain options (except dividend diversification) and authorized dealer
of record as the account from which shares are exchanged, unless otherwise
specified by the
    
                                       33
<PAGE>   36
 
shareholder. In order to establish a systematic withdrawal plan for the new
account or reinvest dividends from the new account into another fund, however,
an exchanging shareholder must file a specific written request. The Fund
reserves the right to reject any order to acquire its shares through exchange.
In addition, the Fund may modify, restrict or terminate the exchange privilege
at any time on 60 days' notice to its shareholders of any termination or
material amendment.
 
  A prospectus of any of these mutual funds may be obtained from any authorized
dealer or the Distributor. An investor considering an exchange to one of such
funds should refer to the prospectus for additional information regarding such
fund prior to investing.
 
  SYSTEMATIC WITHDRAWAL PLAN. Any investor whose shares in a single account
total $10,000 or more at the offering price next computed after receipt of
instructions may establish a monthly, quarterly, semi-annual or annual
withdrawal plan. Any investor whose shares in a single account total $5,000 or
more at the offering price next computed after receipt of instructions may
establish a quarterly, semi-annual or annual withdrawal plan. This plan provides
for the orderly use of the entire account, not only the income but also the
capital, if necessary. Each withdrawal constitutes a redemption of shares on
which any capital gain or loss will be recognized. The planholder may arrange
for monthly, quarterly, semi-annual, or annual checks in any amount not less
than $25. Such a systematic withdrawal plan may also be maintained by an
investor purchasing shares for a retirement plan established on a form made
available by the Fund. See "Shareholder Services -- Retirement Plans."
 
  Class B shareholders and Class C shareholders who establish a withdrawal plan
may redeem up to 12% annually of the shareholder's initial account balance
without incurring a CDSC. Initial account balance means the amount of the
shareholder's investment at the time the election to participate in the plan is
made.
 
   
  Under the plan, sufficient shares of the Fund are redeemed to provide the
amount of the periodic withdrawal payment. Dividends and capital gains
distributions on shares held under the plan are reinvested in additional shares
at the next determined net asset value. If periodic withdrawals continuously
exceed reinvested dividends and capital gains distributions, the shareholder's
original investment will be correspondingly reduced and ultimately exhausted.
Withdrawals made concurrently with the purchase of additional shares ordinarily
will be disadvantageous to the shareholder because of the duplication of sales
charges. Any gain or loss realized by the shareholder upon redemption of shares
is a taxable event.
    
 
   
  INTERNET TRANSACTIONS. In addition to performing transactions on your account
through written instruction or by telephone, you may also perform certain
transactions through the internet. Please refer to our web site at www.vkac.com
for further instruction. VKAC and the Fund employ procedures considered by them
to be
    
 
                                       34
<PAGE>   37
 
   
reasonable to confirm that instructions communicated through the internet are
genuine. Such procedures include requiring use of a personal identification
number prior to acting upon internet instructions and providing written
confirmation of instructions communicated through the internet. If reasonable
procedures are employed, neither VKAC nor the Fund will be liable for following
instructions through the internet which it reasonably believes to be genuine. If
an account has multiple owners, ACCESS may rely on the instructions of any one
owner.
    
 
- ------------------------------------------------------------------------------
REDEMPTION OF SHARES
- ------------------------------------------------------------------------------
 
  REGULAR REDEMPTIONS. Shareholders may redeem for cash some or all of their
shares of the Fund at any time. To do so, a written request in proper form must
be sent directly to ACCESS, P.O. Box 418256, Kansas City, Missouri 64141-9256.
Shareholders may also place redemption requests through an authorized dealer.
Orders received from authorized dealers must be at least $500 unless transmitted
via the FUNDSERV network. The redemption price for such shares is the net asset
value next calculated after an order is received by an authorized dealer
provided such order is transmitted to the Distributor prior to the Distributor's
close of business on such day. It is the responsibility of authorized dealers to
transmit redemption requests received by them to the Distributor so they will be
received prior to such time.
 
  As described herein under "Purchase of Shares," redemptions of Class B shares
and Class C shares are subject to a CDSC. A CDSC of 1.00% may be imposed on
certain redemptions of Class A shares made within one year of purchase for
investments of $1 million or more. The CDSC incurred upon redemption is paid to
the Distributor in reimbursement for distribution-related expenses. A custodian
of a retirement plan account may charge fees based on the custodian's fee
schedule.
 
   
  The request for redemption must be signed by all persons in whose names the
shares are registered. Signatures must conform exactly to the account
registration. If the proceeds of the redemption exceed $50,000, or if the
proceeds are not to be paid to the record owner at the record address, or if the
record address has changed within the previous 30 days, signature(s) must be
guaranteed by one of the following: a bank or trust company; a broker-dealer; a
credit union; a national securities exchange; registered securities association
or clearing agency; a savings and loan association; or a federal savings bank.
    
 
  Generally, a properly signed written request with any required signature
guarantee is all that is required for a redemption. In some cases, however,
other documents may be necessary. For example, although the Fund normally does
not issue certificates for shares, it will do so if a special request has been
made to ACCESS. In the case of shareholders holding certificates, the
certificates for the shares being redeemed must accompany the redemption
request. In the event the redemption is
 
                                       35
<PAGE>   38
 
   
requested by a corporation, partnership, trust, fiduciary, executor or
administrator, and the name and title of the individual(s) authorizing such
redemption is not shown in the account registration, a copy of the corporate
resolution or other legal documentation appointing the authorized signer and
certified within the prior 120 days must accompany the redemption request. IRA
redemption requests should be sent to the IRA custodian to be forwarded to
ACCESS. Where Van Kampen American Capital Trust Company serves as IRA custodian,
special IRA, 403(b)(7), or Keogh distribution forms must be obtained from and be
forwarded to Van Kampen American Capital Trust Company, P.O. Box 944, Houston,
Texas 77001-0944. Contact the custodian for information.
    
 
   
  In the case of redemption requests sent directly to ACCESS, the redemption
price is the net asset value per share next determined after the request is
received in proper form. Payment for shares redeemed will be made by check
mailed within seven days after acceptance by ACCESS of the request and any other
necessary documents in proper order. Such payment may be postponed or the right
of redemption suspended as provided by the rules of the SEC. If the shares to be
redeemed have been recently purchased by check, ACCESS may delay mailing a
redemption check until it confirms the purchase check has cleared, which may
take up to fifteen days. A taxable gain or loss will be recognized by the
shareholder upon the redemption of shares.
    
 
   
  TELEPHONE REDEMPTIONS. In addition to the regular redemption procedures set
forth above, the Fund permits redemption of shares by telephone and for
redemption proceeds to be sent to the address of record for the account or to
the bank account of record, as described below. To establish such privilege, a
shareholder must complete the appropriate section of the application
accompanying this Prospectus or call the Fund at (800) 341-2911 to request that
a copy of the Telephone Redemption Authorization form be sent to them for
completion. To redeem shares, contact the telephone transaction line at (800)
421-5684. VKAC and the Fund employ procedures considered by them to be
reasonable to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring certain personal identification information
prior to acting upon telephone instructions, tape recording telephone
communications and providing written confirmation of instructions communicated
by telephone. If reasonable procedures are employed, neither VKAC nor the Fund
will be liable for following telephone instructions which it reasonably believes
to be genuine. VKAC and the Fund may be liable for any losses due to
unauthorized or fraudulent instructions if reasonable procedures are not
followed. Telephone redemptions may not be available if the shareholder cannot
reach ACCESS by telephone, whether because all telephone lines are busy or for
any other reason; in such case, a shareholder would have to use the Fund's
regular redemption procedure previously described. Requests received by ACCESS
prior to 4:00 p.m., New York time, on a regular business day will be processed
at the net asset value per share determined that day. These privileges are
    
                                       36
<PAGE>   39
 
available for all accounts other than retirement accounts. The telephone
redemption privilege is not available for shares represented by certificates. If
an account has multiple owners, ACCESS may rely on the instructions of any one
owner.
 
  For redemptions authorized by telephone, amounts of $50,000 or less may be
redeemed daily if the proceeds are to be paid by check and amounts of at least
$1,000 up to $1 million may be redeemed daily if the proceeds are to be paid by
wire. The proceeds must be payable to the shareholder(s) of record and sent to
the address of record for the account or wired directly to their predesignated
bank account. This privilege is not available if the address of record has been
changed within 30 days prior to a telephone redemption request. Proceeds from
redemptions are expected to be wired on the next business day following the date
of redemption. This service is also not available with respect to shares held in
an individual retirement account (IRA) for which Van Kampen American Capital
Trust Company acts as custodian. The Fund reserves the right at any time to
terminate, limit or otherwise modify this redemption privilege.
 
   
  GENERAL REDEMPTION INFORMATION. The Fund may redeem any shareholder account
with a net asset value on the date of the notice of redemption less than the
minimum initial investment as specified in this Prospectus. At least 60 days
advance written notice of any such involuntary redemption will be given and the
shareholder will be given an opportunity to purchase the required value of
additional shares at the next determined net asset value without sales charge.
Any involuntary redemption may only occur if the shareholder account is less
than the minimum initial investment due to shareholder redemptions.
    
 
   
  REDEMPTION UPON DEATH OR DISABILITY. The Fund will waive the CDSC on
redemptions following the death or disability of a Class B shareholder or Class
C shareholder. An individual will be considered disabled for this purpose if he
or she meets the definition thereof in Section 72(m)(7) of the Code, which in
pertinent part defines a person as disabled if such person "is unable to engage
in any substantial gainful activity by reason of any medically determinable
physical or mental impairment which can be expected to result in death or to be
of long-continued and indefinite duration." While the Fund does not specifically
adopt the balance of the Code's definition which pertains to furnishing the
Secretary of Treasury with such proof as he or she may require, the Distributor
will require satisfactory proof of disability before it determines to waive the
CDSC on Class B shares and Class C shares.
    
 
   
  In cases of death or disability, the CDSC on Class B shares and Class C shares
will be waived where the decedent or disabled person is either an individual
shareholder or owns the shares as a joint tenant with right of survivorship or
is the beneficial owner of a custodial or fiduciary account, and where the
redemption is made within one year of the death or the initial determination of
disability. This waiver of the CDSC on Class B shares and Class C shares applies
to a total or
    
                                       37
<PAGE>   40
 
   
partial redemption, but only to redemptions of shares held at the time of the
death or the initial determination of disability.
    
 
  REINSTATEMENT PRIVILEGE. A Class A shareholder or Class B shareholder who has
redeemed shares of the Fund may reinstate any portion or all of the net proceeds
of such redemption in Class A shares of the Fund. A Class C shareholder who has
redeemed shares of the Fund may reinstate any portion or all of the proceeds of
such redemption in Class C shares of the Fund with credit given for any CDSC
paid upon such redemption. Such reinstatement is made at the net asset value
(without sales charge except as described under "Shareholder
Services -- Exchange Privilege") next determined after the order is received,
which must be within 180 days after the date of the redemption. Reinstatement at
net asset value is also offered to participants in those eligible retirement
plans held or administered by Van Kampen American Capital Trust Company for
repayment of principal (and interest) on their borrowings on such plans.
 
- ------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS
- ------------------------------------------------------------------------------
 
  The 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.
The 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 spend 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 being implemented through an agreement with the Distributor and
sub-agreements between the Distributor and brokers, dealers or financial
intermediaries (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance.
 
  CLASS A SHARES. The Fund may spend an aggregate amount up to 0.25% per year of
the average daily net assets attributable to the Class A shares of the Fund
pursuant to the Distribution Plan and Service Plan. From such amount, the Fund
may spend up to 0.25% per year of the Fund's 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 brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts. The Fund pays
the Distributor the lesser of the balance of the 0.25% not paid to such brokers,
dealers or financial intermediaries or the amount of the Distributor's actual
distribution-related expense. The rates above are 0.15% with respect to Class A
shares in accounts existing on or before September 30, 1989.
 
                                       38
<PAGE>   41
 
  CLASS B SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class B shares of the Fund pursuant to the
Distribution Plan. In addition, the 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 brokers, dealers or financial
intermediaries and in connection with the maintenance of such shareholders'
accounts.
 
  CLASS C SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class C shares of the Fund pursuant to the
Distribution Plan. From such amount, the Fund, or the Distributor as agent for
the Fund, pays brokers, dealers or 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 broker's, dealer's or financial intermediary's customers. The Fund
pays the Distributor the lesser of the balance of 0.75% not paid to such
brokers, dealers or financial intermediaries or the amount of the Distributor's
actual distribution-related expense attributable to the Class C shares. In
addition, the Fund may spend up to 0.25% per year of the 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 brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts.
 
  OTHER INFORMATION. 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 or Class C
shares for any given year may exceed the amounts payable to the Distributor with
respect to such class of shares under the Distribution Plan, the Service Plan
and payments received pursuant to the CDSC. In such event, with respect to any
such class of 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 Fund does not impose any limit with respect to the number of years into
the future that such unreimbursed expenses may be carried forward (on a Fund
level basis). Because such expenses are accounted on a Fund level basis, in
periods of extreme net asset value fluctuation such amounts with respect to a
particular Class B share or Class C share may be greater or less than the amount
of the initial commission (including carrying cost) paid by the Distributor with
respect to such share. In such circumstances, a shareholder of a share may be
deemed to incur expenses attributable to other shareholders of such class. As of
December 31, 1997, there were
    
                                       39
<PAGE>   42
 
   
$18,598,876 and $579,431 of unreimbursed distribution-related expenses with
respect to Class B shares and Class C shares, respectively, representing 3.34%
and 1.01% of the Fund's net assets attributable to Class B shares and Class C
shares, respectively. If the Distribution Plan was terminated or not continued,
the Fund would not be contractually obligated to pay the Distributor for any
expenses not previously reimbursed by the Fund or recovered through CDSCs.
    
 
  The Distributor will not use the proceeds from the CDSC applicable to a
particular class of shares to defray distribution-related expenses attributable
to any other class of shares. Various federal and state laws prohibit national
banks and some state-chartered commercial banks from underwriting or dealing in
the Fund's shares. In addition, state securities laws on this issue may differ
from the interpretations of federal law, and banks and financial institutions
may be required to register as dealers pursuant to state law. In the unlikely
event that a court were to find that these laws prevent such banks from
providing such services described above, the Fund would seek alternate providers
and expects that shareholders would not experience any disadvantage.
 
- ------------------------------------------------------------------------------
DISTRIBUTIONS FROM THE FUND
- ------------------------------------------------------------------------------
 
  In addition to any increase in the value of shares which the Fund may achieve,
shareholders may receive two kinds of return from the Fund: dividends and
capital gains distributions.
 
  DIVIDENDS. Dividends from stocks and interest earned from other investments
are the Fund's main source of income. Substantially all of this income, less
expenses, is distributed annually as dividends to shareholders. Unless the
shareholder instructs otherwise, dividends are automatically reinvested in
additional shares of the Fund at the next determined net asset value. See
"Shareholder Services -- Reinvestment Plan."
 
  The per share dividends on Class B shares and Class C shares will be lower
than the per share dividends on Class A shares as a result of the higher
distribution fees and transfer agency costs applicable to such classes of
shares.
 
  CAPITAL GAINS. The Fund may realize capital gains or losses when it sells
securities, depending on whether the sales prices for the securities are higher
or lower than their purchase prices. The Fund distributes to shareholders at
least once a year the excess, if any, of its total profits on the sale of
securities during the year over its total losses on the sale of securities,
including capital losses carried forward from prior years under tax laws. As in
the case of dividends, capital gains distributions are automatically reinvested
in additional shares of the Fund at the next determined net asset value unless
the shareholder elects otherwise. See "Shareholder Services -- Reinvestment
Plan."

- ------------------------------------------------------------------------------
TAX STATUS
- ------------------------------------------------------------------------------
 
   
  FEDERAL INCOME TAXATION OF THE FUND.  The Fund has elected and qualified and
intends to continue to qualify each year to be treated as a regulated investment
company under Subchapter M of the Code. To qualify as a regulated investment
company, the Fund must comply with certain requirements of the Code relating to,
among other things, the source of its income and diversification of its assets.
    
 
  If the Fund so qualifies and distributes each year to its shareholders at
least 90% of its net investment income (including tax-exempt interest, taxable
income and net short-term capital gain, but not net capital gains, which are the
excess of net long-term capital gains over net short-term capital losses), it
will not be required to pay federal income taxes on any income distributed to
shareholders. The Fund intends to distribute at least the minimum amount of net
investment income necessary to satisfy the 90% distribution requirement. The
Fund will not be subject to federal income tax on any net capital gains
distributed to shareholders.
 
  In order to avoid a 4% excise tax, the Fund will be required to distribute, by
December 31 of each year, at least 98% of its ordinary income (not including
tax-exempt income) for such year and at least 98% of its capital gain net income
(the latter of which generally is computed on the basis of the one-year period
ending on October 31 of such year), plus any amounts that were not distributed
in previous taxable years. For purposes of the excise tax, any ordinary income
or capital gain net income retained by, and subject to federal income tax in the
hands of, the Fund will be treated as having been distributed.
 
  If the Fund failed to qualify as a regulated investment company or failed to
satisfy the 90% distribution requirement in any taxable year, the Fund would be
taxed as an ordinary corporation on its taxable income (even if such income were
distributed to its shareholders) and all distributions out of earnings and
profits would be taxed to shareholders as ordinary income. To qualify again as a
regulated investment company in a subsequent year, the Fund may be required to
pay an interest charge on 50% of its earnings and profits attributable to
non-regulated investment company years and would be required to distribute such
earnings and profits to shareholders (less any interest charge). In addition, if
the Fund failed to qualify as a regulated investment company for its first
taxable year or, if immediately after qualifying as a regulated investment
company for any taxable year, it failed to qualify for a period greater than one
taxable year, the Fund would be required to recognize any net built-in gains
(the excess of aggregate gains, including items of income, over aggregate losses
that would have been realized if it had been liquidated) in order to qualify as
a regulated investment company in a subsequent year.
 
                                       41
<PAGE>   44
 
   
  Some of the Fund's investment practices are subject to special provisions of
the Code that, among other things, may defer the use of certain losses of the
Fund and affect the holding period of the securities held by the Fund and the
character of the gains or losses realized by the Fund. These provisions may also
require the Fund to recognize income or gain without receiving cash with which
to make distributions in amounts necessary to satisfy the 90% distribution
requirement and the distribution requirements for avoiding income and excise
taxes. The Fund will monitor its transactions and may make certain tax elections
in order to mitigate the effect of these rules and prevent disqualification of
the Fund as a regulated investment company.
    
 
   
  Investments of the Fund in securities issued at a discount or providing for
deferred interest or payment of interest in kind are subject to special tax
rules that will affect the amount, timing and character of distributions to
shareholders. For example, with respect to securities issued at a discount, the
Fund will be required to accrue as income each year a portion of the discount
and to distribute such income each year in order to maintain its qualification
as a regulated investment company and to avoid income and excise taxes. In order
to generate sufficient cash to make distributions necessary to satisfy the 90%
distribution requirement and to avoid income and excise taxes, the Fund may have
to dispose of securities that it would otherwise have continued to hold.
    
 
   
  The Fund may invest in the stock of "passive foreign investment companies"
("PFICs"). A PFIC is a foreign corporation that, in general, meets either of the
following tests: (i) at least 75% of its gross income is passive income or (ii)
an average of at least 50% of its assets produce, or are held for the production
of, passive income. Under certain circumstances, a regulated investment company
that holds stock of a PFIC will be subject to federal income tax on (i) a
portion of any "excess distribution" received on such stock or (ii) any gain
from a sale or disposition of such stock (collectively, "PFIC income"), plus
interest on such amounts, even if the regulated investment company distributes
the PFIC income as a taxable dividend to its shareholders. The balance of the
PFIC income will be included in the regulated investment company's investment
company taxable income and, accordingly, will not be taxable to it to the extent
that income is distributed to its shareholders. If the Fund invests in a PFIC
and elects to treat the PFIC as a "qualified electing fund," then in lieu of the
foregoing tax and interest obligation, the Fund would be required to include in
income each year its pro rata share of the qualified electing fund's annual
ordinary earnings and net capital gain, which most likely would have to be
distributed to satisfy the 90% distribution requirement and the distribution
requirement for avoiding income and excise taxes. In most instances it will be
very difficult to make this election due to certain requirements imposed with
respect to the election.
    
 
                                       42
<PAGE>   45
 
   
  As an alternative to making the above-described election to treat the PFIC as
a qualified electing fund, the Fund may make an election to annually
mark-to-market certain publicly traded PFIC stock (a "PFIC Mark-to-Market
Election"). "Marking-to-market," in this context, means recognizing as ordinary
income or loss each year an amount equal to the difference between the Fund's
adjusted tax basis in such PFIC stock and its fair market value. Losses will be
allowed only to the extent of net mark-to-market gain previously included by the
Fund pursuant to the election for prior taxable years. The Fund may be required
to include in its taxable income for the first taxable year in which it makes a
PFIC Mark-to-Market Election an amount equal to the interest charge that would
otherwise accrue with respect to distributions on, or dispositions of, the PFIC
stock. This amount would not be deductible from the Fund's taxable income. The
PFIC Mark-to-Market Election applies to the taxable year for which made and to
all subsequent taxable years, unless the PFIC stock ceases to be publicly traded
or the Internal Revenue Service consents to revocation of the election. By
making the PFIC Mark-to-Market Election, the Fund could ameliorate the adverse
tax consequences arising from its ownership of PFIC stock, but in any particular
year may be required to recognize income in excess of the distributions it
receives from the PFIC and proceeds from the dispositions of PFIC stock.
    
 
   
  DISTRIBUTIONS.  Distributions of the Fund's net investment income are taxable
to shareholders as ordinary income to the extent of the Fund's earnings and
profits, whether paid in cash or reinvested in additional shares. Distributions
of the Fund's net capital gains ("capital gain dividends"), if any, are taxable
to shareholders as long-term capital gains regardless of the length of time
shares of the Fund have been held by such shareholders. Distributions in excess
of the Fund's earnings and profits will first reduce the adjusted tax basis of a
holder's shares and, after such adjusted tax basis is reduced to zero, will
constitute capital gains to such holder (assuming such shares are held as a
capital asset). For a summary of the tax rates applicable to capital gains
(including capital gain dividends), see "Capital Gains Rates Under the 1997 Tax
Act" below. Tax-exempt shareholders not subject to federal income tax on their
income generally will not be taxed on distributions from the Fund.
    
 
  Shareholders receiving distributions in the form of additional shares issued
by the Fund will be treated for federal income tax purposes as receiving a
distribution in an amount equal to the fair market value of the shares received,
determined as of the distribution date. The basis of such shares will equal the
fair market value on the distribution date.
 
   
  The Fund will inform shareholders of the source and tax status of all
distributions promptly after the close of each calendar year. Some portion of
the distributions from the Fund may be eligible for the dividends received
deduction for corporations
    
 
                                       43
<PAGE>   46
 
   
if the Fund receives qualifying dividends during the year and if certain other
requirements of the Code are satisfied.
    
 
  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in such month and paid during January of the
following year will be treated as having been distributed by the Fund and
received by the shareholders on the December 31 prior to the date of payment. In
addition, certain other distributions made after the close of a taxable year of
the Fund may be "spilled back" and treated as paid by the Fund (except for
purposes of the 4% excise tax) during such taxable year. In such case,
shareholders will be treated as having received such dividends in the taxable
year in which the distribution was actually made.
 
   
  Income from investments in foreign securities received by the Fund may be
subject to income, withholding and other taxes imposed by foreign countries and
U.S. possessions. Such taxes will not be deductible or creditable by
shareholders. Tax conventions between certain countries and the United States
may reduce or eliminate such taxes.
    
 
   
  Under code Section 988, foreign currency gains or losses from certain forward
contracts not traded in the interbank market as well as certain other gains or
losses attributable to currency exchange rate fluctuations are typically treated
as ordinary income or loss. Such income or loss may increase or decrease (or
possibly eliminate) the Fund's income available for distribution. If, under the
rules governing the tax treatment of foreign currency gains and losses, the
Fund's income available for distribution is decreased or eliminated, all or a
portion of the dividends declared by the Fund may be treated for federal income
tax purposes as a return of capital or, in some circumstances, as capital gain.
Generally, a shareholder's tax basis in Fund shares will be reduced to the
extent that an amount distributed to such shareholder is treated as a return of
capital.
    
 
   
  The Fund is required, in certain circumstances, to withhold 31% of dividends
and certain other payments, including redemptions, paid to shareholders who do
not furnish to the Fund their correct taxpayer identification number (in the
case of individuals, their social security number) and certain required
certifications or who are otherwise subject to backup withholding.
    
 
   
  SALE OF SHARES.  The sale of shares (including transfers in connection with a
redemption or repurchase of shares) will be a taxable transaction for federal
income tax purposes. Selling shareholders will generally recognize gain or loss
in an amount equal to the difference between their adjusted tax basis in the
shares and the amount received. If such shares are held as a capital asset, the
gain or loss will be long-term if such shares have been held for more than one
year. For a summary of the tax rates applicable to capital gains, see "Capital
Gains Rates Under the
    
 
                                       44
<PAGE>   47
 
   
1997 Tax Act" below. Any loss recognized upon a taxable disposition of shares
held for six months or less will be treated as a long-term capital loss to the
extent of any capital gain dividends received with respect to such shares. For
purposes of determining whether shares have been held for six months or less,
the holding period is suspended for any periods during which the shareholder's
risk of loss is diminished as a result of holding one or more other positions in
substantially similar or related property or through certain options or short
sales.
    
 
   
  CAPITAL GAINS RATES UNDER THE 1997 TAX ACT.  Under the Taxpayer Relief Act of
1977 (the "1997 Tax Act"), the maximum tax rate applicable to net capital gains
recognized by individuals and other non-corporate taxpayers is (i) the same as
the maximum ordinary income rate for capital assets held for one year or less,
(ii) 28% for capital assets held for more than one year but not more than 18
months and (iii) 20% for capital assets held for more than 18 months. The
maximum net capital gains rate for corporations remains at 35%. The new tax
rates for capital gains described above will apply to distributions of capital
gains dividends by the Fund (if, as expected, the Fund designates capital gain
dividends as 28% rate gain distributions or 20% rate gain distributions, in
accordance with its holding periods for the securities sold that generated such
capital gain dividends) as well as to sales and exchanges of shares in the Fund.
With respect to capital losses recognized on dispositions of shares held six
months or less where such losses are treated as long-term capital losses to the
extent of prior capital gains dividends received on such shares (see "Sale of
Shares" above), it is unclear how such capital losses offset the capital gains
referred to above. Shareholders should consult their own tax advisors as to the
application of the new capital gains rates to their particular circumstances.
    
 
   
  GENERAL.  The federal, state and local income tax discussion set forth above
is for general information only. Prospective investors should consult their
advisors regarding the specific federal tax consequences of purchasing, holding
and disposing of shares, as well as the effects of state, local and foreign tax
law and any proposed tax law changes.
    
 
- ------------------------------------------------------------------------------
FUND PERFORMANCE
- ------------------------------------------------------------------------------
 
  From time to time, the Fund may advertise its total return for prior periods.
Any such advertisement would include at least average annual total return
quotations for one, five and ten year periods. Other total return quotations,
aggregate or average, over other time periods may also be included.
 
  The total return of the Fund for a particular period represents the increase
(or decrease) in the value of a hypothetical investment in the Fund from the
beginning to the end of the period. Total return is calculated by subtracting
the value of the initial investment from the ending value and showing the
difference as a percentage
 
                                       45
<PAGE>   48
 
of the initial investment; the calculation assumes the initial investment is
made at the current maximum public offering price (which includes a maximum
sales charge of 5.75% for Class A shares); that all income dividends or capital
gains distributions during the period are reinvested in Fund shares at net asset
value; and that any applicable CDSC has been paid. The Fund's total return will
vary depending on market conditions, the securities comprising the Fund's
portfolio, the Fund's operating expenses and unrealized net capital gains or
losses during the period. Since shares of the Fund were offered at a maximum
sales charge of 8.50% prior to June 12, 1989, actual Fund total return would
have been somewhat less than that computed on the basis of the current maximum
sales charge. Total return is based on historical earnings and asset value
fluctuations and is not intended to indicate future performance. No adjustments
are made to reflect any income taxes payable by shareholders on dividends and
distributions paid by the Fund.
 
  Average annual total return quotations for periods of two or more years are
computed by finding the average annual compounded rate of return over the period
that would equate the initial amount invested to the ending redeemable value.
 
  Total return is calculated separately for Class A shares, Class B shares and
Class C shares of the Fund. Class A share total return figures include the
maximum sales charge of 5.75%; Class B share and Class C share total return
figures include any applicable CDSC. Because of the differences in sales charges
and distribution fees, the total returns for each of the classes will differ.
 
  From time to time, the Fund may include in its sales literature and
shareholder reports a quotation of the current "distribution rate" for each
class of shares of the Fund. Distribution rate is a measure of the level of
income and short-term capital gain dividends, if any, distributed for a
specified period. Distribution rate differs from yield, which is a measure of
the income actually earned by the Fund's investments, and from total return
which is a measure of the income actually earned by the Fund's investments plus
the effect of any realized and unrealized appreciation or depreciation of such
investments during a stated period. Distribution rate is, therefore, not
intended to be a complete measure of the Fund's performance. Distribution rate
may sometimes be greater than yield since, for instance, it may not include the
effect of amortization of bond premiums, and may include non-recurring
short-term capital gains and premiums from futures transactions engaged in by
the Fund. Distribution rates will be computed separately for each class of the
Fund's shares.
 
   
  In reports or other communications to shareholders or in advertising material,
the Fund may compare its performance with that of other mutual funds as listed
in the ratings or rankings prepared by Lipper Analytical Services, Inc., CDA,
Morningstar Mutual Funds or similar independent services which monitor the
performance of mutual funds, with the Consumer Price Index, the Dow Jones
Industrial Average Index, Standard & Poor's indices, NASDAQ Composite Index,
other appropriate
    
                                       46
<PAGE>   49
 
indices of investment securities, or with investment or savings vehicles. The
performance information may also include evaluations of the Fund published by
nationally recognized ranking services and by nationally recognized financial
publications. Such comparative performance information will be stated in the
same terms in which the comparative data or indices are stated. Such
advertisements and sales material may also include a yield quotation as of a
current period. In each case, such total return and yield information, if any,
will be calculated pursuant to rules established by the SEC and will be computed
separately for each class of the Fund's shares. For these purposes, the
performance of the Fund, as well as the performance of other mutual funds or
indices, do not reflect sales charges, the inclusion of which would reduce Fund
performance. The Fund will include performance data for each class of shares of
the Fund in any advertisement or information including performance data of the
Fund.
 
  The Fund may also utilize performance information in hypothetical
illustrations provided in narrative form. These hypotheticals will be
accompanied by the standard performance information required by the SEC as
described above.
 
   
  The Fund's Annual Report and Semi-Annual Report contains additional
performance information. A copy of the Annual Report and Semi-Annual Report may
be obtained without charge by calling or writing the Fund at the telephone
number and address printed on the cover of this Prospectus.
    
 
- ------------------------------------------------------------------------------
DESCRIPTION OF SHARES OF THE FUND
- ------------------------------------------------------------------------------
 
  The Fund was originally incorporated in Delaware on September 18, 1953 and was
reincorporated in the State of Maryland on January 12, 1979. The Fund was again
reorganized as a business trust under the laws of Delaware as of August 5, 1995
and adopted its current name at that time.
 
   
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, par value $0.01 per share, divided into classes.
The Fund currently offers three classes of shares, designated Class A shares,
Class B shares and Class C shares. Other classes may be established from time to
time in accordance with provisions of the Fund's Declaration of Trust. Each
class of shares represents an interest in the same assets of the Fund and
generally are identical in all respects except that each class bears certain
distribution expenses and has exclusive voting rights with respect to its
distribution fee. Except as described herein, there are no conversion,
preemptive or other subscription rights. In the event of liquidation, each of
the shares of the Fund is entitled to its portion of all of the Fund's net
assets after all debt and expenses of the Fund have been paid. Since Class B
shares and Class C shares pay higher distribution fees and transfer agency
costs, the liquidation proceeds to Class B shareholders and Class C shareholders
are likely to be lower than to other shareholders.
    
 
                                       47
<PAGE>   50
 
  The Fund does not contemplate holding regular meetings of shareholders to
elect Trustees or otherwise. However, the holders of 10% or more of the
outstanding shares may by written request require a meeting to consider the
removal of Trustees by a vote of two-thirds of the shares then outstanding cast
in person or by proxy at such meeting. The Fund will assist such holders in
communicating with other shareholders of the Fund to the extent required by the
1940 Act. More detailed information concerning the Fund is set forth in the
Statement of Additional Information.
 
  The Fund's Declaration of Trust provides that no Trustee, officer or
shareholder of the Fund shall be held to any personal liability, nor shall
resort be had to their private property for the satisfaction of any obligation
or liability of the Fund but the assets of the Fund only shall be liable.

  This Prospectus and the Statement of Additional Information do not contain all
the information set forth in the Registration Statement filed by the Fund with
the SEC under the Securities Act of 1933. Copies of the Registration Statement
may be obtained at a reasonable charge from the SEC or may be examined, without
charge, at the office of the SEC in Washington, D.C.
 
  The fiscal year end of the Fund is December 31. The Fund sends to its
shareholders at least semi-annually reports showing the Fund's portfolio and
other information. An annual report, containing financial statements audited by
the Fund's independent accountants, is sent to shareholders each year. After the
end of each year, shareholders will receive federal income tax information
regarding dividends and capital gains distributions.

GENERAL INFORMATION
 
   
     The Fund was originally incorporated as the American Capital Enterprise
Fund, Inc. as a Delaware corporation on September 18, 1953. The Fund was
reincorporated by merger into a Maryland corporation on January 12, 1979. As of
August 5, 1995, the Fund was reorganized as a series of Van Kampen American
Capital Enterprise Fund (the "Trust"), organized as a business trust, under the
laws of the State of Delaware, and adopted its current name.
    
 
   
     Van Kampen American Capital Asset Management, Inc. (the "Adviser"), Van
Kampen American Capital Distributors, Inc. (the "Distributor") and ACCESS
Investor Services, Inc. ("ACCESS") are wholly-owned subsidiaries of Van Kampen
American Capital, Inc. ("VKAC"), which is an indirect subsidiary of Morgan
Stanley Dean Witter & Co. The principal office of the Fund, the Adviser, the
Distributor and VKAC is located at One Parkview Plaza, Oakbrook Terrace,
Illinois 60181.
    
 
   
     Morgan Stanley Dean Witter & Co. and various of its directly or indirectly
owned subsidiaries, including Morgan Stanley Asset Management Inc., an
investment adviser, Morgan Stanley & Co. Incorporated, a registered
broker-dealer and investment adviser, and Morgan Stanley International, are
engaged in a wide range of financial services. Their principal businesses
include securities underwriting, distribution and trading; merger, acquisition,
restructuring and other corporate finance advisory activities; merchant banking;
stock brokerage and research services; credit services; asset management;
trading of futures, options, foreign exchange, commodities and swaps (involving
foreign exchange, commodities, indices and interest rates); real estate advice,
financing and investing; and global custody, securities clearance services and
securities lending.
    
 
   
     VKAC offers one of the industry's broadest lines of
investments -- encompassing mutual funds, closed-end funds and unit investment
trusts -- and is currently the nation's 5th largest broker-sold mutual fund
group according to Strategic Insight, July 1995. VKAC manages or supervises more
than $60 billion in mutual funds, closed-end funds and unit investment
trusts -- assets which have been entrusted to VKAC in more than 2 million
investor accounts. VKAC has one of the largest research teams (outside of the
rating agencies) in the country, with more than 80 analysts devoted to various
specializations.
    
 
     VKAC uses an investment process designed to attempt to produce consistently
good short-term results, which should help lead to superior long-term
performance.
 
   
     Fully Invested: Money invested in a VKAC stock fund will normally be fully
invested in the market to attempt to maximize the potential for long-term
returns. The importance of being fully invested can be illustrated by the
following comparison. By missing the 30 best months during the past 72 years,
the value of $1.00 invested in 1926 was $25.98 at the end of 1997, compared to
$1,828.33 for $1.00 that was invested for the entire period (Source: Micropal,
Inc.). Of course, past performance is no guarantee of future results.
    
 
     Broadly Diversified: A broadly diversified portfolio usually reduces risk
and increases relative stability. Since VKAC's goal is consistency, a broadly
diversified portfolio across industries is emphasized. VKAC stock funds are
varied both in terms of the number of industries and the number of stocks within
each industry in which they invest. Generally, the stock funds invest in 12
broad economic sectors, and in many individual stocks within each sector.
 
     Clearly Defined: The basic characteristics of VKAC funds are determined by
a pre-defined profile which remains constant over time.

REPURCHASE AGREEMENTS
 
   
     The Fund may enter into repurchase agreements with domestic banks or
broker-dealers deemed to be creditworthy by the Adviser under guidelines
approved by the Trustees. A repurchase agreement is a short-term investment in
which the purchaser (i.e., the Fund) acquires ownership of a debt security and
the seller agrees to repurchase the obligation at a future time and set price,
usually not more than seven days from the date of purchase, thereby determining
the yield during the purchaser's holding period. Repurchase agreements are fully
collateralized by the underlying debt securities and are considered to be loans
under the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund
pays for such securities only upon physical delivery or evidence of book entry
transfer to the account of a custodian or bank acting as agent. The seller under
a repurchase agreement will be required to maintain the value of the underlying
securities marked-to-market daily at not less than the repurchase price. The
underlying securities (normally securities of the U.S. Government, or its
agencies and instrumentalities) may have maturity dates exceeding one year. The
Fund does not bear the risk of a decline in value of the underlying security
unless the seller defaults under its repurchase obligation. In the event of a
bankruptcy or other default of a seller of a repurchase agreement, the Fund
could experience both delays in liquidating the underlying securities and loss
including: (a) possible decline in the value of the underlying security during
the period while the Fund seeks to enforce its rights thereto, (b) possible lack
of access to income on the underlying security during this period, and (c)
expenses of enforcing its rights. The Fund will not invest in repurchase
agreements maturing in more than seven days if any such investments, together
with any other illiquid security held by the Fund, exceeds 10% of the value of
its net assets. See "Investment Practice -- Repurchase Agreements" in the
Prospectus for further information.
    
 
   
OPTIONS, FUTURES CONTRACTS AND RELATED OPTIONS
    
 
WRITING CALL AND PUT OPTIONS
 
     Purpose. The principal reason for writing options is to obtain, through
receipt of premiums, a greater current return than would be realized on the
underlying securities alone. Such current return could be expected to fluctuate
because premiums earned from an option writing program and dividend or interest
income yields on portfolio securities vary as economic and market conditions
change. Writing options on portfolio securities is likely to result in higher
portfolio turnover rate.
 
   
     Writing Options. The purchaser of a call option pays a premium to the
writer (i.e., the seller) for the right to buy the underlying security from the
writer at a specified price during a certain period. The Fund would write call
options only on a covered basis, or for cross-hedging purposes. A call option is
covered if, at all times during the option period, the Fund would own or have
the right to acquire securities of the type that it would be obligated to
deliver if any outstanding option were exercised. An option is for cross-hedging
purposes
    
 
                                       B-3
<PAGE>   56
 
   
if it is not covered by the security subject to the option, but is designed to
provide a hedge against another security which the Fund owns or has the right to
acquire. In such circumstances, the Fund collateralizes the option by
maintaining in a segregated account with the Fund's Custodian, cash or liquid
securities in an amount not less than the market value of the underlying
security, marked-to-market daily, while the option is outstanding.
    
 
     The purchaser of a put option pays a premium to the writer (i.e., the
seller) for the right to sell the underlying security to the writer at a
specified price during a certain period. The Fund would write put options only
on a secured basis, which means that, at all times during the option period, the
Fund would maintain in a segregated account with its Custodian cash or liquid
securities in an amount of not less than the exercise price of the option, or
would hold a put on the same underlying security at an equal or greater exercise
price.
 
     Closing Purchase Transactions and Offsetting Transactions. In order to
terminate its position as a writer of a call or put option, the Fund could enter
into a "closing purchase transaction," which is the purchase of a call (put) on
the same underlying security and having the same exercise price and expiration
date as the call (put) previously written by the Fund. The Fund would realize a
gain (loss) if the premium plus commission paid in the closing purchase
transaction is less (greater) than the premium it received on the sale of the
option. The Fund would also realize a gain if an option it has written lapses
unexercised.
 
     The Fund could write options that are listed on an exchange as well as
options which are privately negotiated in over-the-counter transactions. A Fund
could close out its position as a writer of an option only if a liquid secondary
market exists for options of that series, but there is no assurance that such a
market will exist, particularly in the case of over-the-counter options, since
they can be closed out only with the other party to the transaction.
Alternatively, the Fund could purchase an offsetting option, which would not
close out its position as a writer, but would provide an asset of equal value to
its obligation under the option written. If the Fund is not able to enter into a
closing purchase transaction or to purchase an offsetting option with respect to
an option it has written, it will be required to maintain the securities subject
to the call or the collateral underlying the put until a closing purchase
transaction can be entered into (or the option is exercised or expires), even
though it might not be advantageous to do so.
 
     Risks of Writing Options. By writing a call option, the Fund loses the
potential for gain on the underlying security above the exercise price while the
option is outstanding; by writing a put option a Fund might become obligated to
purchase the underlying security at an exercise price that exceeds the then
current market price.
 
     Each of the exchanges has established limitations governing the maximum
number of call or put options on the same underlying security (whether or not
covered) that may be written by a single investor, whether acting alone or in
concert with others, regardless of whether such options are written on one or
more accounts or through one or more brokers. An exchange may order the
liquidation of positions found to be in violation of those limits, and it may
impose other sanctions or restrictions. These position limits may restrict the
number of options the Fund may be able to write.
 
PURCHASING CALL AND PUT OPTIONS
 
     The Fund could purchase call options to protect (i.e., hedge) against
anticipated increases in the prices of securities it wishes to acquire.
Alternatively, call options could be purchased for capital appreciation. Since
the premium paid for a call option is typically a small fraction of the price of
the underlying security, a given amount of funds will purchase call options
covering a much larger quantity of such security than could be purchased
directly. By purchasing call options, the Fund could benefit from any
significant increase in the price of the underlying security to a greater extent
than had it invested the same amount in the security directly. However, because
of the very high volatility of option premiums, the Fund would bear a
significant risk of losing the entire premium if the price of the underlying
security did not rise sufficiently, or if it did not do so before the option
expired.
 
     Put options may be purchased to protect (i.e., hedge) against anticipated
declines in the market value of either specific portfolio securities or of the
Fund's assets generally. Alternatively, put options may be
 
                                       B-4
<PAGE>   57
 
purchased for capital appreciation in anticipation of a price decline in the
underlying security and a corresponding increase in the value of the put option.
The purchase of put options for capital appreciation involves the same
significant risk of loss as described above for call options.
 
     In any case, the purchase of options for capital appreciation would
increase the Fund's volatility by increasing the impact of changes in the market
price of the underlying securities on the Fund's net asset value.
 
OPTIONS ON STOCK INDEXES
 
   
     Options on stock indices are similar to options on stock, but the delivery
requirements are different. Instead of giving the right to take or make delivery
of stock at a specified price, an option on a stock index gives the holder the
right to receive an amount of cash which will depend upon the closing level of
the stock index upon which the option is based being greater than (in the case
of a call) or less than (in the case of a put) the exercise price of the option.
The amount of cash received will be the difference between the closing price of
the index and the exercise price of the option, multiplied by a specified dollar
multiple. The writer of the option is obligated, in return for the premium
received, to make delivery of this amount.
    
 
   
     Some stock index options are based on a broad market index such as the
Standard & Poor's 500 or the New York Stock Exchange Composite Index, or a
narrower index such as the Standard & Poor's 100. Indices are also based on an
industry or market segment such as the AMEX Oil and Gas Index or the Computer
and Business Equipment Index. A stock index fluctuates with changes in the
market values of the stocks included in the index. Options are currently traded
on The Chicago Board Options Exchange, the American Stock Exchange and other
exchanges.
    
 
     Gain or loss to the Fund on transactions in stock index options will depend
on price movements in the stock market generally (or in a particular industry or
segment of the market) rather than price movements of individual securities. As
with stock options, the Fund may offset its position in stock index options
prior to expiration by entering into a closing transaction on an exchange, or it
may let the option expire unexercised.
 
FUTURES CONTRACTS
 
   
     The Fund may engage in transactions involving futures contracts and related
options in accordance with the rules and interpretations of the Commodity
Futures Trading Commission ("CFTC") under which the Fund would be exempt from
registration as a "commodity pool."
    
 
   
     A stock index futures contract is an agreement pursuant to which a party
agrees to take or make delivery of cash equal to a specified dollar amount times
the difference between the stock index value at a specified time and the price
at which the futures contract is originally struck. No physical delivery of the
underlying stocks in the index is made. Currently, stock index futures contracts
can be purchased with respect to the Standard & Poor's 500 Stock Index on the
Chicago Mercantile Exchange ("CME"), the New York Stock Exchange Composite Index
on the New York Futures Exchange and the Value Line Stock Index on the Kansas
City Board of Trade. Differences in the stocks included in the indices may
result in differences in correlation of the futures contracts with movements in
the value of the securities being hedged.
    
 
     An interest rate futures contract is an agreement pursuant to which a party
agrees to take or make delivery of a specified debt security (such as U.S.
Treasury bonds or notes) at a specified future time and at a specified price.
 
   
     The Fund also may invest in foreign stock index futures traded outside the
United States. Foreign stock index futures traded outside the United States
include the Nikkei Index of 225 Japanese stocks traded on the Singapore
International Monetary Exchange ("Nikkei Index"), Osaka Index of 50 Japanese
stocks traded on the Osaka Exchange, Financial Times Stock Exchange Index of the
100 largest stocks on the London Stock Exchange, the All Ordinaries Share Price
Index of 307 stocks on the Sydney, Melbourne Exchanges, Hang Seng Index of 33
stocks on the Hong Kong Stock Exchange, Barclays Share Price Index of 40 stocks
on the New Zealand Stock Exchange and Toronto Index of 35 stocks on the Toronto
Stock Exchange. Futures and futures options on the Nikkei Index are traded on
the Chicago Mercantile Exchange and United States commodity exchanges may
develop futures and futures options on other indices of foreign securities.
    
                                       B-5
<PAGE>   58
 
Investments in securities of foreign entities and securities denominated in
foreign currencies involve risks not typically involved in domestic investment,
including fluctuations in foreign exchange rates, future foreign political and
economic developments, and the possible imposition of exchange controls or other
foreign or United States governmental laws or restrictions applicable to such
investments.
 
     Initial and Variation Margin. In contrast to the purchase or sale of a
security, no price is paid or received upon the purchase or sale of a futures
contract. Initially, the Fund is required to deposit with its Custodian in an
account in the broker's name an amount of cash or liquid securities equal to a
percentage (which will normally range between 2% and 10%) of the contract
amount. This amount is known as initial margin. The nature of initial margin in
futures transactions is different from that of margin in securities transactions
in that futures contract margin does not involve the borrowing of funds by the
customer to finance the transaction. Rather, the initial margin is in the nature
of a performance bond or good faith deposit on the contract, which is returned
to the Fund upon termination of the futures contract and satisfaction of its
contractual obligations. Subsequent payments to and from the broker, called
variation margin, are made on a daily basis as the price of the underlying
securities or index fluctuates, making the long and short positions in the
futures contract more or less valuable, a process known as marking to market.
 
     For example, when the Fund purchases a futures contract and the price of
the underlying security or index rises, that position increases in value, and
the Fund receives from the broker a variation margin payment equal to that
increase in value. Conversely, where the Fund purchases a futures contract and
the value of the underlying security or index declines, the position is less
valuable, and the Fund is required to make a variation margin payment to the
broker.
 
     At any time prior to expiration of the futures contract, the Fund may elect
to terminate the position by taking an opposite position. A final determination
of variation margin is then made, additional cash is required to be paid by or
released to the Fund, and the Fund realizes a loss or a gain.
 
   
     Futures Strategies. When the Fund anticipates a significant market or
market sector advance, the purchase of a futures contract affords a hedge
against not participating in the advance at a time when the Fund is otherwise
fully invested ("anticipatory hedge"). Such purchase of a futures contract
serves as a temporary substitute for the purchase of individual securities,
which may be purchased in an orderly fashion once the market has stabilized. As
individual securities are purchased, an equivalent amount of futures contracts
could be terminated by offsetting sales. The Fund may sell futures contracts in
anticipation of or in a general market or market sector decline that may
adversely affect the market value of the Fund's securities ("defensive hedge").
To the extent that the Fund's portfolio of securities changes in value in
correlation with the underlying security or index, the sale of futures contracts
substantially reduces the risk to the Fund of a market decline and, by so doing,
provides an alternative to the liquidation of securities positions in the Fund
with attendant transaction costs. Ordinarily transaction costs associated with
futures transactions are lower than the transaction costs which would be
incurred in the purchase or sale of the underlying securities.
    
 
   
     Special Risks Associated with Futures Transactions. There are several risks
connected with the use of futures contracts as a hedging device. These include
the risk of imperfect correlation between movements in the price of the futures
contracts and of the underlying securities, the risk of market distortion, the
illiquidity risk and the risk of error in anticipating price movement.
    
 
     There may be an imperfect correlation (or no correlation) between movements
in the price of the futures contracts and of the securities being hedged. The
risk of imperfect correlation increases as the composition of the securities
being hedged diverges from the securities upon which the futures contract is
based. If the price of the futures contract moves less than the price of the
securities being hedged, the hedge will not be fully effective. To compensate
for the imperfect correlation, the Fund could buy or sell futures contracts in a
greater dollar amount than the dollar amount of securities being hedged if the
historical volatility of the securities being hedged is greater than the
historical volatility of the securities underlying the futures contract.
Conversely, the Fund could buy or sell futures contracts in a lesser dollar
amount than the dollar amount of securities being hedged if the historical
volatility of the securities being hedged is less than the historical volatility
of the securities underlying the futures contract. It is also possible that the
value of futures contracts held by the Fund could decline at the same time as
portfolio securities being hedged; if this occurred, the Fund
 
                                       B-6
<PAGE>   59
 
would lose money on the futures contract in addition to suffering a decline in
value in the portfolio securities being hedged.
 
     There is also the risk that the price of futures contracts may not
correlate perfectly with movements in the securities or index underlying the
futures contract due to certain market distortions. First, all participants in
the futures market are subject to margin depository and maintenance
requirements. Rather than meet additional margin depository requirements,
investors may close futures contracts through offsetting transactions, which
could distort the normal relationship between the futures market and the
securities or index underlying the futures contract. Second, from the point of
view of speculators, the deposit requirements in the futures market are less
onerous than margin requirements in the securities markets. Therefore, increased
participation by speculators in the futures markets may cause temporary price
distortions. Due to the possibility of price distortion in the futures markets
and because of the imperfect correlation between movements in futures contracts
and movements in the securities underlying them, a correct forecast of general
market trends by the Adviser may still not result in a successful hedging
transaction.
 
     There is also the risk that futures markets may not be sufficiently liquid.
Futures contracts may be closed out only on an exchange or board of trade that
provides a market for such futures contracts. Although the Fund intends to
purchase or sell futures only on exchanges and boards of trade where there
appears to be an active secondary market, there can be no assurance that an
active secondary market will exist for any particular contract or at any
particular time. In the event of such illiquidity, it might not be possible to
close a futures position and, in the event of adverse price movement, the Fund
would continue to be required to make daily payments of variation margin. Since
the securities being hedged would not be sold until the related futures contract
is sold, an increase, if any, in the price of the securities may to some extent
offset losses on the related futures contract. In such event, the Fund would
lose the benefit of the appreciation in value of the securities.
 
     Successful use of futures is also subject to the Adviser's ability to
correctly predict the direction of movements in the market. For example, if the
Fund hedges against a decline in the market, and market prices instead advance,
the Fund will lose part or all of the benefit of the increase in value of its
securities holdings because it will have offsetting losses in futures contracts.
In such cases, if the Fund has insufficient cash, it may have to sell portfolio
securities at a time when it is disadvantageous to do so in order to meet the
daily variation margin.
 
   
     Although the Fund intends to enter into futures contracts only if there is
an active market for such contracts, there is no assurance that an active market
will exist for the contracts at any particular time. Most U.S. futures exchanges
and boards of trade limit the amount of fluctuation permitted in futures
contract prices during a single trading day. Once the daily limit has been
reached in a particular contract, no trades may be made that day at a price
beyond that limit. It is possible that futures contract prices would move to the
daily limit for several consecutive trading days with little or no trading,
thereby preventing prompt liquidation of futures positions and subjecting some
futures traders to substantial losses. In such event, and in the event of
adverse price movements, the Fund would be required to make daily cash payments
of variation margin. In such circumstances, an increase in the value of the
portion of the portfolio being hedged, if any, may partially or completely
offset losses on the futures contract. However, as described above, there is no
guarantee that the price of the securities being hedged will, in fact, correlate
with the price movements in a futures contract and thus provide an offset to
losses on the futures contract.
    
 
   
     The Fund will not enter into futures contracts or option transactions
(except for closing transactions) other than for bona fide hedging purposes if
immediately thereafter, the sum of its initial margin and premiums on open
futures contracts and options exceeds 5% of the fair market value of the Fund's
assets; however, in the case of an option that is in-the-money at the time of
purchase, the in-the-money amount may be excluded in calculating the 5%
limitation. In order to prevent leverage in connection with the purchase of
futures contracts by the Fund, an amount of cash or liquid securities equal to
the market value of the obligation under the futures contracts (less any related
margin deposits) will be maintained in a segregated account with the custodian.

OPTIONS ON FUTURES CONTRACTS
 
   
     The Fund could also purchase and write options on futures contracts. An
option on a futures contract gives the purchaser the right, in return for the
premium paid, to assume a position in a futures contract (a long position if the
option is a call and a short position if the option is a put) at a specified
exercise price at any time during the option period. As a writer of an option on
a futures contract, the Fund would be subject to initial margin and maintenance
requirements similar to those applicable to futures contracts. In addition, net
option premiums received by the Fund are required to be included as initial
margin deposits. When an option on a futures contract is exercised, delivery of
the futures position is accompanied by cash representing the difference between
the current market price of the futures contract and the exercise price of the
option. The Fund could purchase put options on futures contracts in lieu of, and
for the same purpose as the sale of a futures contract; at the same time, it
could write put options at a lower strike price (a "put bear spread") to offset
part of the cost of the strategy to the Fund. The purchase of call options on
futures contracts is intended to serve the same purpose as the actual purchase
of the futures contracts.
    
 
     Risks of Transactions in Options on Futures Contracts. In addition to the
risks described above which apply to all options transactions, there are several
special risks relating to options on futures. The Adviser will not purchase
options on futures on any exchange unless in the Adviser's opinion, a liquid
secondary exchange market for such options exists. Compared to the use of
futures, the purchase of options on futures involves less potential risk to the
Fund because the maximum amount at risk is the premium paid for the options
(plus transaction costs). However, there may be circumstances, such as when
there is no movement in the level of the index or in the price of the underlying
security, when the use of an option on a future would result in a loss to the
Fund when the use of a future would not.
 
ADDITIONAL RISKS OF OPTIONS AND FUTURES TRANSACTIONS
 
     In the event of the bankruptcy of a broker through which the Fund engages
in transactions in options, futures or related options, the Fund could
experience delays or losses in liquidating open positions purchased or incur a
loss of all or part of its margin deposits with the broker. Transactions are
entered into by the Fund only with brokers or financial institutions deemed
creditworthy by the Adviser.
 
     Each of the exchanges has established limitations governing the maximum
number of call or put options on the same underlying security or futures
contract (whether or not covered) which may be written by a single investor,
whether acting alone or in concert with others (regardless of whether such
options are written on the same or different exchanges or are held or written on
one or more accounts or through one or more brokers). Option positions of all
investment companies advised by the Adviser are combined for purposes of these
limits. An exchange may order the liquidation of positions found to be in
violation of these limits and it may impose other sanctions or restrictions.
These position limits may restrict the number of listed options which the Fund
may write.
 
   
INVESTMENT RESTRICTIONS
    
 
     The Fund has adopted the following fundamental investment restrictions

     Each trustee/director holds the same position with each of the funds in the
Fund Complex. As of the date of this Statement of Additional Information, there
are 64 operating funds in the Fund Complex. For purposes of the following
compensation and benefits discussion, the Fund Complex is divided into the
following three groups: the funds advised by Asset Management (the "AC Funds"),
the funds advised by Advisory Corp. excluding funds organized as series of the
Morgan Stanley Fund, Inc. (the "VK Funds") and the funds advised by Advisory
Corp. organized as series of the Morgan Stanley Fund, Inc. (the "MS Funds").
Each
                                      B-16
<PAGE>   69
 
   
trustee/director who is not an affiliated person of the Advisers, the
Distributor, ACCESS, Van Kampen American Capital 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
(except the money market series of the MS Funds) provides a deferred
compensation plan to its Non-Affiliated Trustees that allows trustees/directors
to defer receipt of their compensation and earn a return on such deferred
amounts. Deferring compensation has the economic effect as if the Non-Affiliated
Trustee reinvested his or her compensation into the funds. Each fund in the Fund
Complex (except the money market series of the MS Funds) 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 trustees recently reviewed and adopted a standardized compensation and
benefits program for each fund in the Fund Complex. Effective January 1, 1998,
the compensation of each Non-Affiliated Trustee includes an annual retainer in
an amount equal to $50,000 per calendar year, due in four quarterly installments
on the first business day of each quarter. Payment of the annual retainer is
allocated among the funds in the Fund Complex (except the money market series of
the MS Funds) on the basis of the relative net assets of each fund as of the
last business day of the preceding calendar quarter. Effective January 1, 1998,
the compensation of each Non-Affiliated Trustee includes a per meeting fee from
each fund in the Fund Complex (except the money market series of the MS Funds)
in the amount of $200 per quarterly or special meeting attended by the
Non-Affiliated Trustee, due on the date of the 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.
 
     For each AC Fund's last fiscal year and the period up to and including
December 31, 1997, the compensation of each Non-Affiliated Trustee from 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.
 
     For each VK Fund's last fiscal year and the period up to and including
December 31, 1997, the compensation of each Non-Affiliated Trustee from each VK
Fund 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 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.
 
     For the period from July 2, 1997 up to and including December 31, 1997, the
compensation of each Non-Affiliated Trustee from the MS Funds was based
generally on the compensation amounts and methodology used by such funds prior
to their joining the current Fund Complex on July 2, 1997. Each trustee/director
was elected as a director of the MS Funds on July 2, 1997. Prior to July 2,
1997, the MS Funds were part of another fund complex (the "Prior Complex") and
the former directors of the MS Funds were paid an aggregate fee allocated among
the funds in the Prior Complex that resulted in individual directors receiving
                                      B-17
<PAGE>   70
 
total compensation between approximately $8,000 to $10,000 from the MS Funds
during such funds' last fiscal year.
 
   
     Under the deferred compensation plan, 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 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. To
the extent permitted by the 1940 Act, the 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 Fund.
    
 
     Under the retirement plan, a Non-Affiliated Trustee who is receiving
compensation from such Fund prior to such Non-Affiliated Trustee's retirement,
has at least 10 years of service (including years of service prior to adoption
of the retirement plan) 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 retirement from such Fund. Non-Affiliated Trustees
retiring prior to the age of 60 or with fewer than 10 years but more than 5
years of service may receive reduced retirement benefits from such Fund. Each
trustee/director has served as a member of the Board of Trustees of the Fund
since he or she was first appointed or elected in the year set forth below. The
retirement plan contains a Fund Complex retirement benefit cap of $60,000 per
year.
 
     Additional information regarding compensation and benefits for trustees is
set forth below for the periods described in the notes accompanying the table.

    member of the Board of Trustees, but was a member of the Board of Trustees
    during the Fund's most recently completed fiscal year. Mr. Robinson retired
    from the Board of Trustees on December 31, 1997. Messrs. DeMartini and
    McDonnell, also trustees of the Fund during all or a portion of the Fund's
    last fiscal year, are not included in the compensation table because they
    are affiliated persons of the Advisers and are not eligible for compensation
    or retirement benefits from the Fund.
    
 
   
(2) The amounts shown in this column represent the Aggregate Compensation before
    Deferral with respect to the Fund's fiscal year ended December 31, 1997. The
    following trustees deferred compensation from the Fund during the fiscal
    year ended December 31, 1997: Mr. Branagan, $2,560; Ms. Heagy, $2,560; Mr.
    Kennedy, $1,280; Mr. Nelson, $2,560; Mr. Robinson, $2,560; Mr. Rooney,
    $1,280; Dr. Sisto, $1,280;

<PAGE>   71
 
   
    and Mr. Whalen, $2,560. Amounts deferred are retained by the Fund and earn a
    rate of return determined by reference to either the return on the common
    shares of the 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. 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 cumulative deferred
    compensation (including interest) accrued with respect to each trustee,
    including former trustees, from the Fund as of December 31, 1997 is as
    follows: Mr. Branagan, $3,721; Dr. Caruso, $14,397; Mr. Gaughan, $1,131; Ms.
    Heagy, $6,587; Mr. Kennedy, $4,301; Mr. Lipshire, $5,593; Mr. Miller,
    $3,909; Mr. Nelson, $7,285; Mr. Rees, $40,636; Mr. Robinson, $7,379; Mr.
    Rooney, $1,291; Dr. Sisto, $31,663; Mr. Vernon, $7,252; and Mr. Whalen,
    $7,278. The deferred compensation plan is described above the Compensation
    Table.
    
 
   
(3) The amounts shown in this column represent the sum of the retirement
    benefits expected to be accrued by the operating investment companies in the
    Fund Complex for each of the current trustees for the funds' fiscal years
    ended in 1997. The retirement plan is described above the Compensation
    Table.
    
 
   
(4) For Mr. Robinson this is the sum of the actual annual benefits payable by
    the operating investment companies in the Fund Complex as of the date of his
    retirement for each year of the 10-year period since his retirement. For the
    remaining trustees, this is the sum of the estimated maximum annual benefits
    payable by the operating investment companies in the Fund Complex for each
    year of the 10-year period commencing in the year of such trustee's
    anticipated retirement. The Retirement Plan is described above the
    Compensation Table.
    
 
   
(5) The amounts shown in this column represent the aggregate compensation paid
    by all operating investment companies in the Fund Complex as of December 31,
    1997 before deferral by the trustees under the deferred compensation plan.
    Because the funds in the Fund Complex have different fiscal year ends, the
    amounts shown in this column are presented on a calendar year basis. Certain
    trustees deferred all or a portion of their aggregate compensation from the
    Fund Complex during the calendar year ended December 31, 1997. 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. To the extent permitted by the 1940 Act, the Fund may invest in
    securities of those investment companies selected by the Non-Affiliated
    Trustees in order to match the deferred compensation obligation. The
    Advisers and their affiliates also serve as investment adviser for other
    investment companies; however, with the exception of Mr. Whalen, the
    Non-Affiliated Trustees were not trustees of such investment companies.
    Combining the Fund Complex with other investment companies advised by the
    Advisers and their affiliates, Mr. Whalen received Total Compensation of
    $268,447 during the calendar year ended December 31, 1997.
    
 
   
     As of April 2, 1998, the trustees and officers of the Fund as a group owned
less than 1% of the Fund's outstanding shares.

INVESTMENT ADVISORY AGREEMENT
 
   
     The Fund and the Adviser are parties to an investment advisory agreement
(the "Advisory Agreement"). Under the Advisory Agreement, the Fund retains the
Adviser to manage the investment of its assets and to place orders for the
purchase and sale of its portfolio securities. The Adviser obtains and evaluates
economic, statistical and financial information formulate and implement
investment programs in furtherance of the Fund's investment objectives. The
Adviser also furnishes at no cost to the Fund (except as noted herein) the
services of sufficient executive and clerical personnel for the Fund as are
necessary to prepare registration statements, prospectuses, shareholder reports,
and notices and proxy solicitation materials. In addition, the
    
 
                                      B-19
<PAGE>   72
 
   
Adviser furnishes at no cost to the Fund the services of the Fund's President,
one or more Vice Presidents as needed, and a Secretary.
    
 
   
     Under the Advisory Agreement, the Fund bears the cost of its accounting
services, which includes maintaining its financial books and records and
calculating its daily net asset value. The costs of such accounting services
include the salaries and overhead expenses of a Treasurer or other principal
financial officer and the personnel operating under his direction. Charges are
allocated among the investment companies advised or subadvised by the Adviser. A
portion of these amounts are paid to the Adviser or its parent in reimbursement
of personnel, office space, facilities and equipment costs attributable to the
provision of accounting services to the Fund. The services provided by the
Adviser are at cost. The Fund also pays service fees, distribution fees,
custodian fees, legal and auditing fees, the costs of reports to shareholders
and all other ordinary expenses not specifically assumed by the Adviser. The
Advisory Agreement also provides that the Adviser shall not be liable to the
Fund for any actions or omissions if it acted in good faith without negligence
or misconduct.
    
 
     Under the Advisory Agreement the Fund pays to the Adviser as compensation
for the services rendered, facilities furnished, and expenses paid by it a fee
payable monthly computed on average daily net assets of the Fund at the annual
rate of: 0.50% on the first $1 billion of average net assets; 0.45% on the next
$1 billion of average net assets; 0.40% on the next $1 billion of average net
assets; and 0.35% on the average net assets in excess of $3 billion.
 
   
     The Fund's average net asset value for computing the advisory fee is
determined by taking the average of all of the determinations of net asset value
for each business day during a given calendar month. Such fee is payable for
each calendar month as soon as practicable after the end of that month. The fee
payable to the Adviser is 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 subsidiary of VK/AC Holding, Inc. in
connection with obtaining such payments. The Adviser agrees to use its best
efforts to recapture tender solicitation fees and exchange offer fees for the
Fund's benefit, and to advise the Trustees of the Fund of any other commissions,
fees, brokerage or similar payments which may be possible under applicable laws
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.
    
 
     The Advisory Agreement also provides that, in the event the ordinary
business expenses of the Fund for any fiscal year exceed one and one-half
percent of the first $30 million of the Fund's average net assets, plus one
percent of any excess over $30 million, the compensation due the Adviser will be
reduced by the amount of such excess and that, if a reduction in and refund of
the advisory fee is insufficient, the Adviser will pay the Fund monthly an
amount sufficient to make up the deficiency, subject to readjustment during the
year. Ordinary business expenses include the investment advisory fee and other
operating costs paid by the Fund except (1) interest and taxes, (2) brokerage
commissions, (3) certain litigation and indemnification expenses as described in
the Advisory Agreement and (4) payments made by the Fund pursuant to its
distribution plans (described herein). The Advisory Agreement also provides that
the Adviser shall not be liable to the Fund for any actions or omissions if it
acted in good faith without willful misfeasance, negligence or misconduct.
 
     The Advisory Agreement may be continued from year to year if specifically
approved at least annually (a)(i) by the Fund's Trustees or (ii) by vote of a
majority of the Fund's outstanding voting securities and (b) by the affirmative
vote of a majority of the Trustees who are not parties to the agreement or
interested persons of any such party by votes cast in person at a meeting called
for such purpose. The Advisory Agreement provides that it shall terminate
automatically if assigned and that it may be terminated without penalty by
either party on not more than 60 days' nor less than 30 days' written notice.
 
   
     During the fiscal years ended December 31, 1995, 1996 and 1997, the Adviser
received $5,293,215, $6,853,356 and $9,423,365 respectively, in advisory fees
from the Fund. For such periods the Fund paid $131,706, $262,389 and $268,965
respectively, for the accounting services. A substantial portion of these
amounts was paid to the Adviser in reimbursement of personnel, facilities and
equipment costs attributable to the provision of accounting services to the
Fund.

DISTRIBUTOR
 
   
     The Distributor acts as the principal underwriter of the Fund's shares
pursuant to a written agreement (the "Distribution and Service Agreement"). The
Distributor has the exclusive right to distribute shares of the Fund through
authorized dealers. The Distributor's obligation is an agency or "best efforts"
arrangement under which the Distributor is required to take and pay for only
such shares of the Fund as may be sold to the public. The Distributor is not
obligated to sell any stated number of shares. The Distributor bears the cost of
printing (but not typesetting) prospectuses used in connection with this
offering and certain other costs including the cost of supplemental sales
literature and advertising. The Distribution and Service Agreement is renewable
from year to year if approved (a) by the Fund's Trustees or by a vote of a
majority of the Fund's outstanding voting securities and (b) by the affirmative
vote of a majority of Trustees who are not parties to the Distribution and
Service Agreement or interested persons of any party, by votes cast in person at
a meeting called for such purpose. The Distribution and Service Agreement
provides that it will terminate if assigned, and that it may be terminated
without penalty by either party on 90 days' written notice.
    
 
   
     During the fiscal years ended December 31, 1995, 1996 and 1997, total
commissions on the sale of shares of the Fund were $1,916,437, $3,158,740 and
$4,997,467, respectively. Of such totals, the amount retained by the Distributor
was $238,225, $427,155 and $678,682 respectively. The remainder was reallowed to
dealers.
    
 
DISTRIBUTION AND SERVICE PLANS
 
     The 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.
The 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 sometimes
are referred to herein as the "Plans". The Plans provide that the Fund may spend
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 such class,
respectively. The Distribution Plan and the Service Plan are being implemented
through an agreement (the "Distribution and Service Agreement") with the
Distributor of each class of the Fund's shares, sub-agreements between the
Distributor and members of the NASD who are acting as securities dealers and
NASD members or eligible non-members who are acting as brokers or agents and
similar agreements between the Fund and financial intermediaries who are acting
as brokers (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance, which may include, but not
be limited to, processing purchase and redemption transactions, establishing and
maintaining shareholder accounts regarding the Fund, and such other services as
may be agreed to from time to time and as may be permitted by applicable
statute, rule or regulation. Brokers, dealers and financial intermediaries that
have entered into sub-agreements with the Distributor and sell shares of the
Fund are referred to herein as "financial intermediaries."
 
     The Distributor must submit quarterly reports to the Board of Trustees of
the Trust, of which the Fund is a series, setting forth separately by class of
shares all amounts paid under the Distribution Plan and the purposes for which
such expenditures were made, together with such other information as from time
to time is reasonably requested by the Trustees. The Plans provide that they
will continue in full force and effect from year to year so long as such
continuance is specifically approved by a vote of the Trustees, and also by a
vote of the disinterested Trustees, cast in person at a meeting called for the
purpose of voting on the Plans. Each of the Plans may not be amended to increase
materially the amount to be spent for the services described therein with
respect to any class of shares without approval by a vote of a majority of the
outstanding voting shares of such class, and all material amendments to either
of the Plans must be approved by the Trustees and also by the disinterested
Trustees. Each of the Plans may be terminated with respect to any class of
shares at any time by a vote of a majority of the disinterested Trustees or by a
vote of a majority of the outstanding voting shares of such class.
 
   
     The Distributor has entered into agreements with (i) The Prudential
Insurance Company of America ("Prudential") under which the Fund shall be
offered pursuant to the PruArray Programs; (ii) Smith Barney Inc. ("Smith
Barney") under which the Fund shall be offered pursuant to the MultiChoice
Program; and (iii) Merrill Lynch ("Merrill") under which the Fund shall be
offered pursuant to the Merrill Program.

Trustees and other fiduciaries of retirement plans seeking to invest in multiple
fund families through broker-dealer retirement plan alliance programs should
contact Prudential, Smith Barney or Merrill for further information concerning
the PruArray, MultiChoice and Merrill Programs including, but not limited to,
minimum size and operational requirements.
    
 
   
     For the fiscal year ended December 31, 1997, the Fund's aggregate expenses
under the Plans for Class A shares were $2,667,884 or 0.19% of the Class A
shares' average daily net assets. Such expenses were paid to reimburse the
Distributor for payments to financial intermediaries for servicing Fund
shareholders and for administering the Plans. For the fiscal year ended December
31, 1997, the Fund's aggregate expenses under the Plans for Class B shares were
$4,172,932 or 1.00% of the Class B shares' average net assets. Such expenses
were paid to reimburse the Distributor for the following payments: $3,180,304
for commissions and transaction fees paid to financial intermediaries in respect
of sales of Class B shares of the Fund and $992,628 for fees paid to financial
intermediaries for servicing Class B shareholders and administering the Plans.
For the fiscal year ended December 31, 1997, the Fund's aggregate expenses under
the Plans for Class C shares were $288,641 or 1.00% of the Class C shares'
average daily net assets. Such expenses were paid to reimburse the Distributor
for the following payments: $76,403 for commissions and transaction fees paid to
financial intermediaries in respect to sales of Class C shares of the Fund and
$212,238 fees paid to financial intermediaries for servicing Class C
shareholders and administering the Plans.
    
 
TRANSFER AGENT
 
   
     For the fiscal year ended December 31, 1995, 1996 and 1997, ACCESS,
shareholder service agent and dividend disbursing agent for the Fund, received
fees, determined on a cost plus profit basis, aggregating $2,315,395, $2,759,200
and $3,013,200 respectively, for these services. Beginning in 1998, the transfer
agency fees are determined through negotiations with the Fund's Board of
Trustees and are based on competitive market benchmarks.
    
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
 
     The Adviser is responsible for decisions to buy and sell securities for the
Fund and for the placement of its portfolio business and the negotiation of the
commissions paid on such transactions. It is the policy of the Adviser to seek
the best security price available with respect to each transaction. In
over-the-counter transactions, orders are placed directly with a principal
market maker unless it is believed that a better price and execution can be
obtained by using a broker. Except to the extent that the Fund may pay higher
brokerage commissions for brokerage and research services, as described below,
on a portion of its transactions executed on securities exchanges, the Adviser
seeks the best security price at the most favorable commission rate. In
selecting broker-dealers and in negotiating commissions, the Adviser considers
the firm's reliability, the quality of its execution services on a continuing
basis and its financial condition. When more than one firm is believed to meet
these criteria, preference may be given to firms which also provide research
services to the Fund or the Adviser.
 
     Consistent with the Rules of Fair Practice of the NASD and subject to
seeking best execution and such other policies as the Trustees may determine,
the Adviser may consider sales of shares of the Fund and of the other Van Kampen
American Capital mutual funds as a factor in the selection of firms to execute
portfolio transactions for the Fund.
 
     Section 28(e) of the Securities Exchange Act of 1934 ("Section 28(e)")
permits an investment adviser, under certain circumstances, to cause an account
to pay a broker or dealer who supplies brokerage and research services, a
commission for effecting a securities transaction in excess of the amount of
commission another broker or dealer would have charged for effecting the
transaction. Brokerage and research services include (a) furnishing advice as to
the value of securities, the advisability of investing in, purchasing or selling
securities, and the availability of securities or purchasers or sellers of
securities, (b) furnishing analyses and reports concerning issuers, industries,
securities, economic factors and trends, portfolio strategy, and the performance
of accounts, and (c) effecting securities transactions and performing functions
incidental thereto (such as clearance, settlement and custody).
 
                                      B-22
<PAGE>   75
 
     Pursuant to provisions of the investment advisory agreement, the Fund's
Trustees have authorized the Adviser to cause the Fund to incur brokerage
commissions in an amount higher than the lowest available rate in return for
research services provided to the Adviser. The Adviser is of the opinion that
the continued receipt of supplemental investment research services from dealers
is essential to its provision of high quality portfolio management services to
the Fund. The Adviser undertakes that such higher commissions will not be paid
by the Fund unless (a) the Adviser determines in good faith that the amount is
reasonable in relation to the services in terms of the particular transaction or
in terms of the Adviser's overall responsibilities with respect to the accounts
as to which it exercises investment discretion, (b) such payment is made in
compliance with the provisions of Section 28(e) and other applicable state and
federal laws, and (c) in the opinion of the Adviser, the total commissions paid
by the Fund are reasonable in relation to the expected benefits to the Fund over
the long term. The investment advisory fee paid by the Fund under the investment
advisory agreement is not reduced as a result of the Adviser's receipt of
research services.
 
     The Adviser places portfolio transactions for other advisory accounts
including other investment companies. Research services furnished by firms
through which the Fund effects its securities transactions may be used by the
Adviser in servicing all of its accounts; not all of such services may be used
by the Adviser in connection with the Fund. In the opinion of the Adviser, the
benefits from research services to each of the accounts (including the Fund)
managed by the Adviser cannot be measured separately. Because the volume and
nature of the trading activities of the accounts are not uniform, the amount of
commissions in excess of the lowest available rate paid by each account for
brokerage and research services will vary. However, in the opinion of the
Adviser, such costs to the Fund will not be disproportionate to the benefits
received by the Fund on a continuing basis.
 
   
     The Adviser seeks to allocate portfolio transactions equitably whenever
concurrent decisions are made to purchase or sell securities by the Fund and
another advisory account. In some cases, this procedure could have an adverse
effect on the price or the amount of securities available to the Fund. In making
such allocations among the Fund and other advisory accounts, the main factors
considered by the Adviser are the relative net assets, the respective investment
objectives, the relative size of portfolio holdings of the same or comparable
securities, the availability of cash for investment, the size of investment
commitments generally held, and opinions of the persons responsible for
recommending the investment.
    
 
   
     Brokerage commissions paid by the Fund on portfolio transactions for the
fiscal years ended December 31, 1995, 1996 and 1997 totalled $3,624,963,
$2,575,219 and $2,707,388 respectively. During the year ended December 31, 1997,
the Fund paid $731,064 in brokerage commissions on transactions totalling
$684,446,840 to brokers selected primarily on the basis of research services
provided to the Adviser.
    
 
   
     Effective October 31, 1996, Morgan Stanley Group Inc. ("Morgan Stanley")
became an affiliate of the Adviser. Effective May 31, 1997, Dean Witter & Co.
("Dean Witter") became an affiliate of the Adviser. The negotiated commission
paid to an affiliated broker on any transaction would be comparable to that
payable to a non-affiliated broker in a similar transaction.
    
 
     The Fund paid the following commissions to these brokers during the periods
shown:

DETERMINATION OF NET ASSET VALUE
 
     The net asset value per share is determined as of the close of the New York
Stock Exchange (the "Exchange") (currently 4:00 p.m., New York time) on each
business day on which the Exchange is open. The net asset value of Fund shares
is computed by dividing the value of all securities plus other assets, less
liabilities, by the number of shares outstanding, and adjusting to the nearest
cents per share.
 
   
     Such computation is made by using prices as of the close of trading on the
Exchange and (i) valuing securities traded on a national securities exchange at
the last reported sale price, or if there has been no sale that day, at the mean
between the last reported bid price and asked price, (ii) valuing
over-the-counter securities for which the last sale price is available from the
National Association of Securities Dealers Automated Quotations ("NASDAQ") at
that price, (iii) valuing all other over-the-counter securities for which market
quotations are available at the mean between the most recent bid and asked
prices supplied by NASDAQ or broker-dealers, and (iv) valuing any securities for
which market quotations are not readily available and any other assets at fair
value as determined in good faith by the Adviser based on procedures approved by
the Trustees of the Fund. Short-term investments are valued in the manner
described in the notes to the financial statements included in this Statement of
Additional Information.
    
 
     The assets belonging to the Class A shares, the Class B shares and the
Class C shares will be invested together in a single portfolio. The net asset
value of each class will be determined separately by subtracting the expenses
and liabilities allocated to that class.
 
PURCHASE AND REDEMPTION OF SHARES
 
     The following information supplements the section in the Fund's Prospectus
captioned "Purchase of Shares."
 
   
INVESTMENTS BY MAIL
    
 
     A shareholder investment account may be opened by completing the
application accompanying the Prospectus and forwarding the application, through
the authorized dealer, to ACCESS, at P.O. Box 419319, Kansas City, Missouri
64141-6319. The account is opened only upon acceptance of the application by
ACCESS. The minimum initial investment of at least $500 per class of shares, in
the form of a check payable to the Fund, must accompany the application. This
minimum may be waived by the Distributor for plans involving continuing
investments. Minimum subsequent investments of at least $25 per class of shares
may be mailed directly to ACCESS. All such investments are made at the public
offering price of Fund shares next computed following receipt of payment by
ACCESS. Confirmations of the opening of an account and of all subsequent
transactions in the account are forwarded by ACCESS to the investor's authorized
dealer.

<PAGE>   77
 
     In processing applications and investments, ACCESS acts as agent for the
investor and for the authorized dealer named thereon, and also as agent for the
Distributor, in accordance with the terms of the Prospectus. If ACCESS ceases to
act as such, a successor company named by the Fund will act in the same
capacities so long as the account remains open.
 
LETTER OF INTENT
 
     Purchases of Class A shares of the Participating Funds described above
under "Cumulative Purchase Discount" made pursuant to the Letter of Intent and
still owned are also included in determining the applicable quantity discount. A
Letter of Intent permits an investor to establish a total investment goal to be
achieved by any number of investments over a thirteen-month period. Each
investment made during the period will receive the reduced sales charge
applicable to the amount represented by the goal as if it were a single
investment. Escrowed shares totalling 5% of the dollar amount of the Letter of
Intent are held by ACCESS in the name of the shareholder. The effective date of
a Letter of Intent may be back-dated up to 90 days in order that any investments
made during this 90-day period, valued at the investor's cost, can become
subject to the Letter of Intent. The Letter of Intent does not obligate the
investor to purchase the indicated amount. In the event the Letter of Intent
goal is not achieved within the thirteen-month period, the investor is required
to pay the difference between sales charges otherwise applicable to the
purchases made during this period and sales charges actually paid. Such payment
may be made directly to the Distributor or, if not paid, the Distributor will
liquidate sufficient escrowed shares to obtain such difference. If the goal is
exceeded in an amount which qualifies for a lower sales charge, a price
adjustment is made by refunding to the investor in shares of the Fund, the
amount of excess sales charges, if any, paid during the thirteen-month period.
 
REDEMPTION OF SHARES
 
   
     Redemptions are not made on days during which the Exchange is closed. The
right of redemption may be suspended and the payment therefor may be postponed
for more than seven days during any period when (a) the Exchange is closed for
other than customary weekends or holidays; (b) trading on the Exchange is
restricted; (c) an emergency exists as a result of which disposal by the Fund of
securities owned by it is not reasonably practicable or it is not reasonably
practicable for the Fund to determine fairly the value of its net assets; or (d)
the SEC, by order, so permits.
    
 
CONTINGENT DEFERRED SALES CHARGE -- CLASS A
 
     For investments of $1,000,000 or more of Class A shares of the Fund
("Qualified Purchaser"), the front-end sales charge will be waived and a
contingent deferred sales charge ("CDSC -- Class A") of 1.00% is imposed in the
event of certain redemptions within one year of the purchase. If a CDSC -- Class
A is imposed upon redemption, the amount of the CDSC -- Class A will be equal to
the lesser of 1.00% of the net asset value of the shares at the time of purchase
or 1.00% of the net asset value of the shares at the time of redemption.
 
     The CDSC -- Class A will be imposed only if a Qualified Purchaser redeems
an amount which causes the value of the account to fall below the total dollar
amount of purchase payments made by the Qualified Purchaser without an initial
sales charge during the one-year period prior to the redemption. No CDSC --
Class A will be imposed on exchanges between funds. For purposes of the
CDSC -- Class A, when shares of one fund are exchanged for shares of another
fund, the purchase date for the shares of the fund exchanged into will be
assumed to be the date on which shares were purchased in the fund from which the
exchange was made. If the exchanged shares themselves are acquired through an
exchange, the purchase date is assumed to carry over from the date of the
original election to purchase shares subject to a CDSC -- Class A rather than a
front-end load sales charge. In determining whether a CDSC -- Class A is
payable, it is assumed that shares held the longest are the first to be
redeemed.
 
     Cumulative Purchase Discounts and Letters of Intent apply to the net asset
value privilege. Also, in order to establish an amount of $1,000,000 or more, a
Qualified Purchaser may aggregate shares of the Participating Funds described in
the Prospectus.

WAIVER OF CLASS B AND CLASS C CONTINGENT DEFERRED SALES CHARGE ("CDSC -- CLASS B
AND C").
 
     As described in the Prospectus under "Redemption of Shares", redemptions of
Class B shares and Class C shares will be subject to a CDSC. The CDSC -- Class B
and C is waived on redemptions of Class B shares and Class C shares in the
circumstances described below:
 
   
     (a) Redemption Upon Death or Disability
    
 
     The Fund will waive the CDSC -- Class B and C on redemptions following the
death or disability of a Class B shareholder and Class C shareholder. An
individual will be considered disabled for this purpose if he or she meets the
definition thereof in Section 72(m)(7) of the Internal Revenue Code of 1986, as
amended (the "Code"), which in pertinent part defines a person as disabled if
such person "is unable to engage in any substantial gainful activity by reason
of any medically determinable physical or mental impairment which can be
expected to result in death or to be of long-continued and indefinite duration."
While the Fund does not specifically adopt the balance of the Code's definition
which pertains to furnishing the Secretary of Treasury with such proof as he or
she may require, the Distributor will require satisfactory proof of death or
disability before it determines to waive the CDSC -- Class B and C.
 
   
     In cases of death or disability, the CDSC -- Class B and C will be waived
where the decedent or disabled person is either an individual shareholder or
owns the shares as a joint tenant with right of survivorship or is the
beneficial owner of a custodial or fiduciary account, and where the redemption
is made within one year of the death or initial determination of disability.
This waiver of the CDSC -- Class B and C applies to a total or partial
redemption, but only to redemptions of shares held at the time of the death or
initial determination of disability.
    
 
     (b) Redemption in Connection with Certain Distributions from Retirement
Plans
 
     The Fund will waive the CDSC -- Class B and C when a total or partial
redemption is made in connection with certain distributions from Retirement
Plans. The charge will be waived upon the tax-free rollover or transfer of
assets to another Retirement Plan invested in one or more Van Kampen American
Capital funds; in such event, as described below, the Fund will "tack" the
period for which the original shares were held onto the holding period of the
shares acquired in the transfer or rollover for purposes of determining what, if
any, CDSC -- Class B and C is applicable in the event that such acquired shares
are redeemed following the transfer or rollover. The charge will be waived on
any redemption which results from the return of an excess contribution pursuant
to Section 408(d)(4) or (5) of the Code, the return of excess deferral amounts
pursuant to Code Section 401(k)(8) or 402(g)(2), or from the death or disability
of the employee (see Code Section 72(m)(7) and 72(t)(2)(A)(ii)). In addition,
the charge will be waived on any minimum distribution required to be distributed
in accordance with Code Section 401(a)(9).
 
     The Fund does not intend to waive the CDSC -- Class B and C for any
distributions from IRAs or other Retirement Plans not specifically described
above.
 
     (c) Redemption Pursuant to a Fund's Systematic Withdrawal Plan
 
     A shareholder may elect to participate in a systematic withdrawal plan (the
"Plan") with respect to the shareholder's investment in the Fund. Under the
Plan, a dollar amount of a participating shareholder's investment in the Fund
will be redeemed systematically by the Fund on a periodic basis, and the
proceeds mailed to the shareholder. The amount to be redeemed and frequency of
the systematic withdrawals will be specified by the shareholder upon his or her
election to participate in the Plan. The CDSC -- Class B and C will be waived on
redemptions made under the Plan.
 
   
     The amount of the shareholder's investment in the Fund at the time the
election to participate in the Plan is made with respect to the Fund is
hereinafter referred to as the "initial account balance." The amount to be
systematically redeemed from the Fund without the imposition of a CDSC -- Class
B and C may not exceed a maximum of 12% annually of the shareholder's initial
account balance. The Fund reserves the right to change the terms and conditions
of the Plan and the ability to offer the Plan.
    
 
                                      B-26
<PAGE>   79
 
     (d) Involuntary Redemptions of Shares in Accounts that Do Not Have the
Required Minimum Balance
 
     The Fund reserves the right to redeem shareholder accounts with balances of
less than a specified dollar amount as set forth in the Prospectus. Prior to
such redemptions, shareholders will be notified in writing and allowed a
specified period of time to purchase additional shares to bring the account up
to the required minimum balance. The Fund will waive the CDSC -- Class B and C
upon such involuntary redemption.
 
   
     (e) Reinvestment of Redemption Proceeds in Shares of the Same Fund Within
         180 Days After Redemption
    
 
   
     A shareholder who has redeemed Class C shares of a Fund may reinvest at net
asset value, with credit for any CDSC -- Class C paid on the redeemed shares,
any portion or all of his or her redemption proceeds (plus that amount necessary
to acquire a fractional share to round off his or her purchase to the nearest
full share) in Class C shares of the Fund, provided that the reinvestment is
effected within 180 days after such redemption and the shareholder has not
previously exercised this reinvestment privilege with respect to Class C shares
of the Fund. Shares acquired in this manner will be deemed to have the original
cost and purchase date of the redeemed shares for purposes of applying the
CDSC -- Class C to subsequent redemptions.
    
 
     (f) Redemption by Adviser
 
     The Fund may waive the CDSC -- Class B and C when a total or partial
redemption is made by the Adviser with respect to its investments in the Fund.
 
EXCHANGE PRIVILEGE
 
     The following supplements the discussion of "Shareholder
Services -- Exchange Privilege" in the Prospectus:
 
     By use of the exchange privilege, the investor authorizes ACCESS to act on
telephonic, telegraphic or written exchange instructions from any person
representing himself to be the investor or the agent of the investor and
believed by ACCESS to be genuine. Van Kampen American Capital and its
subsidiaries, including ACCESS, and the Fund employ procedures considered by
them to be reasonable to confirm that instructions communicated by telephone are
genuine. Such procedures include requiring certain personal identification
information prior to acting upon telephone instructions, tape recording
telephone communications, and providing written confirmation of instructions
communicated by telephone. If reasonable procedures are employed, neither Van
Kampen American Capital, ACCESS nor the Fund will be liable for following
telephone instructions which it reasonably believes to be genuine. Van Kampen
American Capital, ACCESS and the Fund may be liable for any losses due to
unauthorized or fraudulent instructions if reasonable procedures are not
followed.
 
     For purposes of determining the sales charge rate previously paid on Class
A shares, all sales charges paid on the exchanged security and on any security
previously exchanged for such security or for any of its predecessors shall be
included. If the exchanged security was acquired through reinvestment, that
security is deemed to have been sold with a sales charge rate equal to the rate
previously paid on the security on which the dividend or distribution was paid.
If a shareholder exchanges less than all of his securities, the security upon
which the highest sale charge rate was previously paid is deemed exchanged
first.
 
     Exchange requests received on a business day prior to the time shares of
the funds involved in the request are priced will be processed on the date of
receipt. "Processing" a request means that shares in the fund from which the
shareholder is withdrawing an investment will be redeemed at the net asset value
per share next determined on the date of receipt. Shares of the new fund into
which the shareholder is investing will also normally be purchased at the net
asset value per share, plus any applicable sales charge, next determined on the
date of receipt. Exchange requests received on a business day after the time
shares of the funds involved in the request are priced will be processed on the
next business day in the manner described herein.
 
     A prospectus of any of these mutual funds may be obtained from any
authorized dealer or the Distributor. An investor considering an exchange to one
of such funds should refer to the prospectus for additional information
regarding such fund.

TAX STATUS OF THE FUND
 
   
     The Trust and each of its series, including the Fund, will be treated as
separate corporations for federal income tax purposes. The Fund will be subject
to tax if, among other things, it fails to distribute net capital gains, or if
its annual distributions, as a percentage of its income, are less than the
distributions required by tax laws.
    
 
FUND PERFORMANCE
 
   
     The Fund's average annual total return (computed in the manner described in
the Prospectus) for Class A shares of the Fund for (i) the one year period ended
December 31, 1997 was 21.18%, (ii) the five year period ended December 31, 1997
was 17.28% and (iii) the ten year period ended December 31, 1997 was 16.93 %.
The average annual total return (computed in the manner described in the
Prospectus) for Class B shares of the Fund for (i) the one year period ended
December 31, 1997 was 22.50%; (ii) the five year period ended December 31, 1997
was 17.53%; and (iii) the six year and eleven day period ended December 31, 1997
was 17.73%. The average annual total return (computed in the manner described in
the Prospectus) for Class C shares of the Fund for (i) the one year period ended
December 31, 1997 was 26.51% and (ii) the three year and five month period ended
December 31, 1997 was 19.15%. These results are based on historical earnings and
asset value fluctuations and are not intended to indicate future performance.
Such information should be considered in light of the Fund's investment
objectives and policies as well as the risks incurred in the Fund's investment
practices. Future results will be affected by changes in the general level of
prices of securities available for purchase and sale by the Fund. The past
one-year, five-year and ten-year periods have been ones of fluctuating stock
prices.
    
 
     Total return is computed separately for Class A shares, Class B shares and
Class C shares.
 
     The Fund may, from time to time: (1) illustrate the benefits of
tax-deferral by comparing taxable investments to investments made through
tax-deferred retirement plans; (2) illustrate in graph or chart form, or
otherwise, the benefits of dollar cost averaging by comparing investments made
pursuant to a systematic investment plan to investments made in a rising market;
(3) illustrate allocations among different types of mutual funds for investors
at different stages of their lives; and (4) in reports or other communications
to shareholders or in advertising material, illustrate the benefits of
compounding at various assumed rates of return. Such illustrations may be in the
form of charts or graphs and will not be based on historical returns experienced
by the Fund.
 
   
     The Fund seeks to remain fully invested and diversified across many
industries to achieve consistent long-term performance. From time to time
marketing materials may provide a portfolio manager update, an Adviser update or
discuss general economic conditions and outlooks. The top 10 holdings of the
Fund may also be listed in marketing pieces. Materials may also mention how Van
Kampen American Capital believes the Fund compares relative to other Van Kampen
American Capital funds. Materials may also discuss the Dalbar Financial Services
study from 1984 to 1994 which examined investor cash flow into and out of all
types of mutual funds. The ten year study found that investors who bought mutual
fund shares and held such shares outperformed investors who bought and sold. The
Dalbar study conclusions were consistent regardless if shareholders purchased
their funds in direct or sales force distribution channels. The study showed
that investors working with a professional representative have tended over time
to earn higher returns than those who invested directly. The Fund will also be
marketed on the Internet.

                       REPORT OF INDEPENDENT ACCOUNTANTS

TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF
VAN KAMPEN AMERICAN CAPITAL ENTERPRISE FUND

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Van Kampen American Capital
Enterprise Fund (the "Fund") at December 31, 1997, and the results of its
operations, the changes in its net assets and the financial highlights for each
of the periods presented, in conformity with generally accepted accounting
principles. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Fund's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at December 31, 1997 by correspondence with the
custodian and brokers and the application of alternative auditing procedures
where confirmations from brokers were not received, provide a reasonable basis
for the opinion expressed above.

                         NOTES TO FINANCIAL STATEMENTS

                               December 31, 1997

1. Significant Accounting Policies

Van Kampen American Capital Enterprise Fund (the "Fund") is organized as a
Delaware business trust, and is registered as a diversified open-end management
investment company under the Investment Company Act of 1940, as amended. The
Fund's investment objective is to seek capital appreciation by investing in a
portfolio of securities consisting principally of common stocks. The Fund
commenced investment operations on January 7, 1954. The distribution of the
Fund's Class B and Class C shares commenced on December 20, 1991 and July 20,
1993, respectively.

   The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION-Investments in securities listed on a securities exchange
are valued at their sale price as of the close of such securities exchange.
Unlisted securities and listed securities for which the last sale price is not
available are valued at the mean of the bid and asked prices or, if not
available, their fair value as determined in accordance with procedures
established in good faith by the Board of Trustees. Short-term securities with
remaining maturities of 60 days or less are valued at amortized cost.

B. SECURITY TRANSACTIONS-Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.

   The Fund may invest in repurchase agreements, which are short-term
investments in which the Fund acquires ownership of a debt security and the
seller agrees to repurchase the security at a future time and specified price.
The Fund may invest independently in repurchase agreements, or transfer
uninvested cash balances into a pooled cash account along with other investment
companies advised by Van Kampen American Capital Asset Management, Inc. (the
"Adviser") or its affiliates, the daily aggregate of which is invested in
repurchase agreements. Repurchase agreements are fully collateralized by the
underlying debt security. The Fund will make payment for such securities only
upon physical delivery or evidence of book entry transfer to the account of the
custodian bank. The seller is required to maintain the value of the underlying
security at not less than the repurchase proceeds due the Fund.

C. INCOME AND EXPENSES-Dividend income is recorded on the ex-dividend date and
interest income is recorded on an accrual basis. Original issue discounts on
debt securities purchased are amortized over the expected life of each
applicable security. Premiums on debt securities are not amortized. Expenses of
the Fund are allocated on a pro rata basis to each class of shares, except for
distribution and service fees and transfer agency costs which are unique to each
class of shares.

D. FEDERAL INCOME TAXES-It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

   At December 31, 1997, for federal income tax purposes, cost of long- and
short-term investments is $1,756,939,019; the aggregate gross unrealized
appreciation is $660,592,590 and the aggregate gross unrealized depreciation is
$51,426,825, resulting in net unrealized appreciation of $609,165,765.

   Net realized gains or losses may differ for financial purposes primarily as a
result of the deferral of losses for tax purposes resulting from wash sales and
the mark to market of open future contracts at December 31, 1997.

E. DISTRIBUTION OF INCOME AND GAINS-The Fund declares and pays dividends
annually from net investment income. Net realized gains, if any, are distributed
annually. Distributions from net realized gains for book purposes may include
short-term capital gains and gains on option and futures transactions. All
short-term capital gains and a portion of option and futures gains are included
in ordinary income for tax purposes.

4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $1,539,298,579 and $1,276,410,517,
respectively.

5. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

  The Fund has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio or generate potential gain. All of the Fund's portfolio holdings,
including derivative instruments, are marked to market each day with the change
in value reflected in the unrealized appreciation/depreciation. Upon
disposition, a realized gain or loss is recognized accordingly, except when
taking delivery of a security underlying a futures contract. In this instance,
the recognition of gain or loss is postponed until the disposal of the security
underlying the futures contract.

  During the period, the Fund invested in futures contracts, a type of
derivative. A futures contract is an agreement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Fund
generally invests in stock index futures. These contracts are generally used to
provide the return of an index without purchasing all of the securities
underlying the index or to manage the Fund's overall exposure to the equity
markets.

  Upon entering into futures contracts, the Fund maintains, in a segregated
account with its custodian, securities with a value equal to its obligation
under the futures contracts. During the period the futures contract is open,
payments are received from or made to the broker based upon changes in the value
of the contract (the variation margin). The risk of loss associated with a
futures contract is in excess of the variation margin reflected on the Statement
of Assets and Liabilities.

shares, ongoing shareholder services and maintenance of shareholder accounts.

  Annual fees under the Plans of up to .25% of Class A net assets and 1.00% each
of Class B and Class C net assets are accrued daily. Included in these fees for

ITEM 27. INDEMNIFICATION.
 
     Reference is made to Article 8, Section 8.4 of the Registrant's Agreement
and Declaration of Trust.
 
     Article 8; Section 8.4 of the Agreement and Declaration of Trust provides
that each officer and trustee of the Registrant shall be indemnified by the
Registrant against all liabilities incurred in connection with the defense or
disposition of any action, suit or other proceeding, whether civil or criminal,
in which the officer or trustee may be or may have been involved by reason of
being or having been an officer or trustee, except that such indemnity shall not
protect any such person against a liability to the Registrant or any shareholder
thereof to which such person would otherwise be subject by reason of (i) not
acting in good faith in the reasonable belief that such person's actions were
not in the best interest of the Trust, (ii) willful misfeasance, bad faith,
gross negligence or reckless disregard of the duties involved in the conduct of
his or her office, or (iii) for a criminal proceeding, not having a reasonable
cause to believe that such conduct was unlawful (collectively "Disabling
Conduct"). Absent a court determination that an officer or trustee seeking
indemnification was not liable on the merits or guilty of Disabling Conduct in
the conduct of his or her office, the
 
                                       C-2
<PAGE>   100
 
decision by the Registrant to indemnify such person must be based upon the
reasonable determination of independent counsel or non-party independent
trustees, after review of the facts, that such officer or trustee is not guilty
of Disabling Conduct in the conduct of his or her office.
 
     The Registrant has purchased insurance on behalf of its officers and
trustees protecting such persons from liability arising from their activities as
officers or trustees of the Registrant. The insurance does not protect or
purport to protect such persons from liability to the Registrant or to its
shareholders to which such officer or trustee would otherwise be subject by
reason of willful misfeasance, bad faith, gross negligence or reckless disregard
of the duties involved in the conduct of their office.
 
     Conditional advancing of indemnification monies may be made if the trustee
or officer undertakes to repay the advance unless it is ultimately determined
that he or she is entitled to the indemnification and only if the following
conditions are met: (1) the trustee or officer provides a security for the
undertaking; (2) the Registrant is insured against losses arising from lawful
advances; or (3) a majority of a quorum of the Registrant's disinterested,
non-party trustees, or an independent legal counsel in a written opinion, shall
determine, based upon a review of readily available facts, that a recipient of
the advance ultimately will be found entitled to indemnification.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Act") may be permitted to trustees, officers and controlling
persons of the Registrant pursuant to the foregoing provisions or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by the trustee, officer, or controlling person of the
Registrant in the successful defense of any action, suit or proceeding) is
asserted by such trustee, officer or controlling person in connection with the
shares being registered, the Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

                  Van Kampen American Capital Enterprise Fund


The undersigned, being the Secretary of Van Kampen American Capital Enterprise
Fund, a Delaware business trust (the "Trust"), pursuant to the authority
conferred upon the Trustees of the Trust by Section 6.1 of the Trust's First
Amended and Restated Agreement and Declaration of Trust ("Declaration"), and by
the affirmative vote of a Majority of the Trustees does hereby amend and
restate in its entirety the Certificate of Designation of the Van Kampen
American Capital Enterprise Fund Series of the Trust dated June 21, 1995 by
redesignating the following classes of Shares of the Trust with the following
rights, preferences and characteristics:

1.  SHARES.  The beneficial interest in the Trust shall be divided into Shares
having a nominal or par value of $0.01 per Share, of which an unlimited number
may be issued, which Shares shall represent interests only in the Trust. The
Trustees shall have the authority from time to time to authorize separate
Series of Shares for the Trust as they deem necessary or desirable.

2.  CLASSES OF SHARES.  The Shares of the Trust shall be initially divided into
three classes--Class A, Class B and Class C. The Trustees shall have the
authority from time to time to authorize additional Classes of Shares of the
Trust.

3.  SALES CHARGES.  Each Class A, Class B and Class C Share shall be subject to
such sales charges, if any, as may be established from time to time by the
Trustees in accordance with the Investment Company Act of 1940 (the "1940 Act")
and applicable rules and regulations of the National Association of Securities
Dealers, Inc., all as set forth in the Trust's prospectus.

4.  CONVERSION.  Each Class B Share and certain Class C Shares of the Trust
shall be converted automatically, and without any action or choice on the part
of the Shareholder thereof, into Class A Shares of the Trust at such times and
pursuant to such terms, conditions and restrictions as may be established by
the Trustees and as set forth in the Trust's Prospectus.

5.  ALLOCATION OF EXPENSES AMONG CLASSES.  Expenses related solely to a
particular Class (including, without limitation, distribution expenses under an
administrative or service agreement, plan or other arrangement, however
designated) shall be borne by that Class and shall be appropriately reflected
(in a manner determined by the Trustees) in the net asset value, dividends,
distribution and liquidation rights of the Shares of that Class.

<PAGE>   2

6.  SPECIAL MEETINGS.  A special meeting of Shareholders of a Class of the
Trust may be called with respect to the Rule 12b-1 distribution plan applicable
to such Class or with respect to any other proper purpose affecting only
holders of shares of such Class at any time by a Majority of the Trustees.

7.  OTHER RIGHTS GOVERNED BY DECLARATION.  All other rights, preferences,
qualifications, limitations and restrictions with respect to Shares of any
Series of the Trust or with respect to any Class of Shares set forth in the
Declaration shall apply to Shares of the Trust unless otherwise specified in
this Certificate of Designation, in which case this Certificate of Designation
shall govern.

8.  AMENDMENTS, ETC.  Subject to the provisions and limitations of Section 9.5
of the Declaration and applicable law, this Certificate of Designation may be
amended by an instrument signed in writing by a Majority of the Trustees (or by
any officer of the Trust pursuant to the vote of a Majority of the Trustees) or
when authorized to do so by the vote in accordance with the Declaration of the
holders of a majority of all the Shares of the Trust outstanding and entitled
to vote or, if such amendment affects the Shares of one or more but not all of
the Classes of the Trust, the holders of a majority of all the Shares of the
affected Classes outstanding and entitled to vote.

9.  INCORPORATION OF DEFINED TERMS.  All capitalized terms which are not
defined herein shall have the same meaning as ascribed to those terms in the
Declaration.

                         INVESTMENT ADVISORY AGREEMENT

AGREEMENT (herein so called) made this May 31, 1997, by and between VAN KAMPEN
AMERICAN CAPITAL ENTERPRISE 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,
prospectus and stated investment objectives, policies and restrictions, shall:

          a. manage the investment and reinvestment of the FUND's assets
including, by way of illustration, the evaluation of pertinent economic,
statistical, financial and other data, determination of the industries and
companies to be represented in the FUND's portfolio, and formulation and
implementation of investment programs;

          b. maintain a trading desk and place all orders for the purchase and
sale of 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, reports, proxy solicitation materials and amendments thereto, the
furnishing of routine legal services except for services provided by outside
counsel to the FUND selected by the Trustees, and the supervision of the FUND's
Treasurer and the personnel working under his direction; and

          d. furnish to the FUND office space, facilities, equipment and
personnel adequate to provide the services described in paragraphs a., b., and
c. above and pay the compensation of each FUND trustee and Fund officer who is

     In performing the services described in paragraph b. above, the ADVISER
shall use its best efforts to obtain for the FUND the most favorable price and
execution available and shall maintain records adequate to demonstrate
compliance with this requirement.  Subject to prior authorization by the FUND's
Trustees of 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
stated to be payable by the ADVISER hereunder, which expenses payable by the
FUND shall include (i) interest and taxes; (ii) brokerage commissions and other
costs in connection with the purchase and sale of portfolio investments; (iii)
compensation of its trustees and officers other than those who are affiliated
persons of the ADVISER; (iv) compensation of its Treasurer, compensation of
personnel working under the Treasurer's direction, and expenses of office space,
facilities, and equipment used by the Treasurer and such personnel in the
performance of their normal duties for the FUND which consist of maintenance of
the accounts, books and other documents which constitute the record forming the
basis for the FUND's financial statements, preparation of such 

<PAGE>   2
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 repurchases or redemptions; (viii) expenses related to the issuance
of its shares against payment therefor by or on behalf of the subscribers
thereto; (ix) fees and related expenses of registering and qualifying the FUND
and its shares for distribution under state and federal securities laws; (x)
expenses of printing and mailing of registration statements, prospectuses,
reports, notices and proxy solicitation materials of the FUND; (xi) all other
expenses incidental to holding meetings of the FUND's shareholders including
proxy solicitations therefor; (xii) expenses for servicing shareholder accounts;
(xiii) insurance 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 obligation which the FUND may have to indemnify its officers and
trustees with respect thereto.  To the extent that any of the foregoing expenses
are allocated 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.

(3) COMPENSATION PAYABLE TO THE 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:

     .50% on the first $1 billion of the FUND's average daily net assets; .45%
on the next $1 billion of the FUND's average daily net assets; .40% on the next
$1 billion of the FUND's average daily net assets; and .35% of any excess over
$3 billion.

     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 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 1.5% of the first $30 million of the FUND's average daily net
assets plus 1% of any excess over $30 million, 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 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 on 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.

     The execution of this Agreement has been authorized by the FUND's Trustees
and by the sole shareholder. This Agreement is executed on behalf of the FUND or
the Trustees of the FUND as Trustees and not individually and that the
obligations of this Agreement are not binding upon any of the Trustees, officers
or shareholders of the FUND individually but are binding only upon the assets
and 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-law principles thereof) of the State of Delaware applicable to
contracts made and to be performed in that state.

     In connection with its employment hereunder, the ADVISER hereby agrees and
covenants not to change its name without the prior consent of the Board of
Trustees of the FUND.

     The parties hereto each have caused this Agreement to be signed in
duplicate on its behalf by its duly authorized officer on the above date.

                       DISTRIBUTION AND SERVICE AGREEMENT


     THIS DISTRIBUTION AND SERVICE AGREEMENT dated as of May 31, 1997 (the
"Agreement") by and between VAN KAMPEN AMERICAN CAPITAL ENTERPRISE FUND (the
"Fund"), and VAN KAMPEN AMERICAN CAPITAL DISTRIBUTORS, INC., a Delaware
corporation (the "Distributor").

     1.   (a)  APPOINTMENT OF DISTRIBUTOR.  The Fund appoints the Distributor as
a principal underwriter and exclusive distributor of each class of its shares of
beneficial interest (the "Shares") offered for sale from time to time pursuant
to the then current prospectus of the Fund, subject to different combinations of
front-end sales charges, distribution fees, service fees and contingent deferred
sales charges.  Classes of shares, if any, subject to a front-end sales charge
and a distribution and/or service fee are referred to herein as "FESC Classes"
and the Shares of such classes are referred to herein as "FESC Shares." Classes
of shares, if any, subject to a contingent-deferred sales charge and a
distribution and/or a service fee are referred to herein as "CDSC Classes" and
Shares of such classes are referred to herein as "CDSC Shares."  Classes of
shares, if any, subject to a front-end sales charge, a contingent-deferred sales
charge and a distribution and/or service fee are referred to herein as
"Combination Classes" and Shares of such class are referred to herein as
"Combination Shares."  The Fund reserves the right to refuse at any time or
times to sell Shares hereunder for any reason deemed adequate by the Board of
Trustees of the Fund.

          (b)  BEST EFFORTS.  The Distributor shall use its best efforts to
sell, through its organization and through other dealers and agents, the Shares
which the Distributor has the right to purchase under Section 2 hereof, but the
Distributor does not undertake to sell any specific number of Shares.  Without
the prior approval of the Board of Trustees, the Distributor shall not, directly
or indirectly, distribute, sell or market, through its organization or other
brokers, dealers or agents, shares of any investment companies unless the Board
of Trustees of the Fund determines that such companies do not compete, or
potentially compete, with the Fund.

          (c)  POSITIONS IN THE SHARES.  The Distributor agrees that it will not
take any long or short positions in the Shares, except for long positions in
those Shares purchased by the Distributor in accordance with any systematic
sales plan described in the then current Prospectus of the Fund and except as
permitted by Section 2 hereof, and that so far as it can control the situation,
it will prevent any of its trustees, officers or shareholders from taking any
long or short positions in the Shares, except for legitimate investment
purposes.

          (d)  ESSENTIAL PERSONNEL.   The Distributor and the Fund agree that
the retention of (i) the chief executive officer, president, treasurer and
secretary of the Distributor, and (ii) each director, officer and employee of
the Distributor 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 Distributor's
acceptance of employment hereunder, the Distributor hereby agrees and covenants
for itself and on behalf of its Affiliates that neither the Distributor nor any
of its Affiliates shall replace or seek to replace any Essential Person or cause
to be replaced any Essential Person, in each case without first consulting with
the Board of Trustees of the Fund in a timely manner.  In addition, neither the
Distributor nor any Affiliate of the Distributor 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 consulting with the Board of
Trustees of the Fund in a timely manner.


     2.   SALE OF SHARES TO DISTRIBUTOR.  The Fund hereby grants to the
Distributor the exclusive right, except as herein otherwise provided, to
purchase Shares directly from the Fund upon the terms herein set forth.  Such
exclusive right hereby granted shall not apply to Shares issued or transferred
or sold at net asset value:  (a) in connection with the merger or consolidation
of the Fund with any other investment company or the acquisition by the Fund of
all or substantially all of the assets of or the outstanding Shares of any
investment company; (b) in connection with a pro rata distribution directly to
the holders of 

<PAGE>   2
Shares in the nature of a stock dividend or stock split or in connection with
any other recapitalization approved by the Board of Trustees; (c) upon the
exercise of purchase or subscription rights granted to the holders of Shares on
a pro rata basis; (d) in connection with the automatic reinvestment of dividends
and distributions from the Fund; or (e) in connection with the issue and sale of
Shares to trustees, officers and employees of the Fund, to directors, officers
and employees of the investment adviser of the Fund or any principal underwriter
(including the Distributor) of the Fund, to retirees of the Distributor that
purchased shares of any mutual fund distributed by the Distributor prior to
retirement, to directors, officers and employees of Van Kampen American Capital,
Inc. (the parent company of the Distributor), VK/AC Holding, Inc. (the parent
company of The Van Kampen American Capital, Inc.), Morgan Stanley, Dean Witter,
Discover & Co. (the parent company of VK/AC Holding, Inc.) and to the
subsidiaries of Van Kampen American Capital, Inc.; (f) to any trust, pension,
profit-sharing or other benefit plan for any of the aforesaid persons; and (g)
to any group of persons as permitted by Rule 22d-1 under the 1940 Act approved
from time to time by the Board of Trustees and set forth in the then current
Prospectus of the Fund.

     The Distributor shall have the right to buy from the Fund the Shares
needed, but not more than the Shares needed (except for reasonable allowances
for clerical errors, delays and errors of transmission and cancellation of
orders) to fill unconditional orders for Shares received by the Distributor from
dealers, agents and investors during each period when particular net asset
values and public offering prices are in effect as provided in Section 3 hereof;
and the price which the Distributor shall pay for the Shares so purchased shall
be the respective net asset value used in determining the public offering price
on which such orders were based.  The Distributor shall notify the Fund at the
end of each such period, or as soon thereafter on that business day as the
orders received in such period have been compiled, of the number of Shares of
each class that the Distributor elects to purchase hereunder.

     3.  (a)  PUBLIC OFFERING PRICE.  The public offering price per Share shall
be determined in accordance with the then current Prospectus of the Fund. In no
event shall the public offering price exceed the net asset value per Share,
plus, with respect to the FESC Shares,  a front-end sales charge not in excess
of the applicable maximum sales charge permitted under the Rules of Fair
Practice of the National Association of Securities Dealers, Inc., as in effect
from time to time.  The net asset value per share for each class of Shares,
respectively, shall be determined in the manner provided in the Declaration of
Trust and By-Laws of the Trust as then amended, the Certificate of Designation
with respect to the Fund, as amended, and in accordance with the then current
Prospectus of the Fund consistent with the terms and conditions of the Fund's
Multiple Class Plan adopted by the Board of Trustees in accordance with Section
18 of the 1940 Act and Rule 18f-3 thereunder. The Fund will cause immediate
notice to be given to the Distributor of each change in net asset value as soon
as it is determined.

          (b)  DISCOUNTS TO DEALERS.  Discounts to dealers purchasing FESC
Shares from the Distributor for resale and to brokers and other eligible agents
making sales of FESC Shares to investors and compensation payable from the
Distributor to dealers, brokers and other eligible agents making sales of CDSC
Shares and Combination Shares shall be set forth in the selling agreements
between the Distributor and such dealers or agents, respectively, as from time
to time amended, and, if such discounts and compensation are described in the
then current Prospectus for the Fund, shall be as so set forth.  In connection
with the Distributor's employment hereunder, the Distributor hereby agrees to
distribute the Shares through brokers, dealers and other agents of Dean Witter
Distributors, Inc. on a "proprietary basis" substantially identical to the
distribution of shares of proprietary open-end investment companies distributed
by Dean Witter Distributors, Inc.


     4.   COMPLIANCE WITH NASD RULES, SEC ORDERS, ETC.  In selling Fund Shares,
the Distributor will in all respects duly comply with all state and federal laws
relating to the sale of such securities and with all applicable rules and
regulations of all regulatory bodies, including without limitation, the Rules of
Fair Practice of the National Association of Securities Dealers, Inc., and all
applicable rules and regulations of the Securities and Exchange Commission under
the 1940 Act, and will indemnify and save the Fund harmless from any damage or
expense on account of any unlawful act by the Distributor or its agents or
employees.  The Distributor is not, however, to be responsible for the acts of
other dealers or agents, 

                                       2
<PAGE>   3
except to the extent that they shall be acting for the Distributor or under its
direction or authority.  None of the Distributor, any dealer, any agent or any
other person is authorized by the Fund to give any information or to make any
representations, other than those contained in the Registration Statement or
Prospectus heretofore or hereafter filed with the Securities and Exchange
Commission under the Securities Act of 1933, as amended (the "1933 Act") (as any
such Registration Statement and Prospectus may have been or may be amended from
time to time), covering the Shares, and in any supplemental information to any
such Prospectus approved by the Fund in connection with the offer or sale of
Shares.  None of the Distributor, any dealer, any broker or any other person is
authorized to act as agent for the Fund in connection with the offering or sale
of Shares to the public or otherwise.  All such sales shall be made by the
Distributor as principal for its own account.

      In selling Shares to investors, the Distributor will adopt and comply with
certain standards, as set forth in Exhibit III attached hereto as to when each
respective class of Shares may appropriately be sold to particular investors.
The Distributor will require every broker, dealer and other eligible agent
participating in the offering of the Shares to agree to adopt and comply with
such standards as a condition precedent to their participation in the offering.

      5.  EXPENSES.

          (a)  The Fund will pay or cause to be paid:

               (i)  all expenses in connection with the registration of
                    Shares under the federal securities laws, and the Fund will
                    exercise its best efforts to obtain said registration and
                    qualification;

               (ii) all expenses in connection with the printing of any notices
                    of shareholders' meetings, proxy and proxy statements and
                    enclosures therewith, as well as any other notice or
                    communication sent to shareholders in connection with any
                    meeting of the shareholders or otherwise, any annual,
                    semiannual or other reports or communications sent to the
                    shareholders, and the expenses of sending prospectuses
                    relating to the Shares to existing shareholders;

               (iii)all expenses of any federal or state original-issue tax
                    or transfer tax payable upon the issuance, transfer or
                    delivery of Shares from the Fund to the Distributor; and

               (iv) the cost of preparing and issuing any Share certificates
                    which may be issued to represent Shares.

         (b)  The Distributor will pay the costs and expenses of qualifying and
maintaining qualification of the Shares for sale under the securities laws of
the various states.  The Distributor will also permit its officers and employees
to serve without compensation as trustees and officers of the Fund if duly
elected to such positions.

         (c)  The Fund shall reimburse the Distributor for out-of-pocket costs
and expenses actually incurred by it in connection with distribution of each
class of Shares respectively in accordance with and subject to the terms of a
plan (the "12b-1 Plan") adopted by the Fund pursuant to Rule 12b-1 under the
1940 Act as such 12b-1 Plan may be in effect from time to time; provided,
however, that no payments shall be due or paid to the Distributor hereunder
with respect to a class of Shares unless and until this Agreement shall have
been approved for each such class by a majority of the Board of Trustees of the
Fund and by a majority of the "Disinterested Trustees" (as such term is defined
in such 12b-1 Plan) by vote cast in person at a meeting called for the purpose
of voting on this Agreement.  A copy of such 12b-1 Plan as in effect on the
date of this Agreement is attached as Exhibit I hereto.  The Fund reserves the
right to terminate such 12b-1 Plan with respect to a class of Shares at any
time, as specified in the Plan.  The persons authorized to direct the payment
of funds pursuant to this Agreement and the 12b-1 Plan shall provide to the
Fund's Board of Trustees, and the Trustees shall review, at least quarterly, a

                                       3
<PAGE>   4

written report with respect to each class of Shares setting forth the amounts
so paid, the purposes for which such expenditures were made for each such class
of Shares, comparing the amounts paid by such class of Shares with amounts paid
by classes of shares issued by investment companies not governed by the Board
of Trustees and distributed by the Distributor or by direct or indirect
Affiliates of the Distributor and such other information as the Board of
Trustees may from time to time request.

          (d)  The Fund shall compensate the Distributor for providing
services to, and the maintenance of, shareholder accounts in the Fund
(including prepaying service fees to eligible brokers, dealers and financial
intermediaries and expenses incurred in connection therewith) and the
Distributor may pay as agent for and on behalf of the Fund a service fee with
respect to each class of Shares to brokers, dealers and financial
intermediaries for the provision of shareholder services and the maintenance of
shareholder accounts in the Fund in the amount with respect to each class of
Shares set forth from time to time in the Fund's prospectus.  The Fund shall
compensate the Distributor for such expenses in accordance with the terms of a
service plan (the "Service Plan"), as such Service Plan may be in effect from
time to time; provided, however, that no service fee payments shall be due or
paid to the Distributor hereunder with respect to a class of Shares unless and
until this Agreement shall have been approved for each such class by a majority
of the Board of Trustees of the Fund and by a majority of the Disinterested
Trustees by vote cast in person at a meeting called for the purpose of voting
on this Agreement.  A copy of such Service Plan as in effect on the date of
this Agreement is attached as Exhibit II hereto.  The Fund reserves the right
to terminate such Service Plan with respect to a class of Shares at any time,
as specified in the Plan.  The persons authorized to direct the payment of
funds pursuant to this Agreement and the Service Plan shall provide to the
Fund's Board of Trustees, and the Trustees shall review, at least quarterly, a
written report with respect to each class of Shares setting forth the amounts
paid as service fees for each such class of Shares comparing the amounts paid
as service fees by such class of Shares with amounts paid by classes of shares
issued by investment companies not governed by the Board of Trustees and
distributed by the Distributor or by direct or indirect Affiliates of the
Distributor and such other information as the Board of Trustees may from time
to time request.

     6.   REDEMPTION OF SHARES.  In connection with the Fund's redemption of
its Shares, the Fund hereby authorizes the Distributor to repurchase, upon the
terms and conditions hereinafter set forth, as the Fund's agent and for the
Fund's account, such Shares as may be offered for sale to the Fund from time to
time by holders of such Shares or their agents.

          (a)  Subject to and in conformity with all applicable federal
and state legislation, any applicable rules of the National Association of
Securities Dealers, Inc., and any applicable rules and regulations of the
Securities and Exchange Commission under the 1940 Act, the Distributor may
accept offers of holders of Shares to resell such Shares to the Fund on such
terms and conditions and at such prices as described and provided for in the
then current Prospectus of the Fund.

          (b)  The Distributor agrees to notify the Fund at such times as
the Fund may specify of the number of each class of Shares, respectively,
repurchased for the Fund's account and the time or times of such repurchases,
and the Fund shall notify the Distributor of the prices and, in the case of a
class of CDSC Shares or Combination Shares, of the deferred sales charge as
described below, if any, applicable to repurchases of Shares of such class.

          (c)  The Fund shall have the right to suspend or revoke the
foregoing authorization at any time; unless otherwise stated, any such
suspension or revocation shall be effective forthwith upon receipt of notice
thereof by telegraph or by written instrument from any of the Fund's officers.
In the event that the Distributor's authorization is, by the terms of such
notice, suspended for more than twenty-four hours or until further notice, the
authorization given by this Section 6 shall not be revived except by vote of
the Board of Trustees of the Fund.

          (d)  The Distributor agrees that all repurchases of Shares made
by the Distributor shall be made only as agent for the Fund's account and
pursuant to the terms and conditions herein set forth.

          (e)  The Fund agrees to authorize and direct its Custodian to
pay, for the Fund's account, the repurchase price (together with any applicable
contingent deferred sales charge) of any Shares so 

                                       4
<PAGE>   5

repurchased for the Fund against the authorized transfer of book shares from an
open account and against delivery of any other documentation required by the
Board of Trustees of the Fund or, in the case of certificated Shares, against
delivery of the certificates representing such Shares in proper form for
transfer to the Fund.

          (f)  The Distributor shall receive no commissions or other
compensation in respect of any repurchases of FESC Shares for the Fund under the
foregoing authorization and appointment as agent.  With respect to any
repurchase of CDSC Shares or Combination Shares, the Distributor shall receive
the deferred sales charge, if any, applicable to the respective class of Shares
that have been held for less than a specified period of time with respect to
such class as set forth from time to time in the Fund's Prospectus.  The
Distributor shall receive no other commission or other compensation in respect
of any repurchases of CDSC Shares or Combination Shares for the Fund under the
foregoing authorization and appointment as agent.

          (g)  If any FESC Shares sold to the Distributor under the terms of
this Agreement are redeemed or repurchased by the Fund or by the Distributor as
agent or are tendered for redemption within seven business days after the date
of the Distributor's confirmation of the original purchase by the Distributor,
the Distributor shall forfeit the amount above the net asset value received by
it in respect of such Shares, provided that the portion, if any, of such amount
re-allowed by the Distributor to dealers or agents shall be repayable to the
Fund only to the extent recovered by the Distributor from the dealer or agent
concerned.  The Distributor shall include in agreements with such dealers and
agents a corresponding provision for the forfeiture by them of their concession
with respect to FESC Shares purchased by them or their principals and redeemed
or repurchased by the Fund or by the Distributor as agent within seven business
days after the date of the Distributor's confirmation of such initial purchases.

     7.  INDEMNIFICATION.  The Fund agrees to indemnify and hold harmless the
Distributor and each of its trustees and officers and each person, if any, who
controls the Distributor within the meaning of Section 15 of the 1933 Act
against any loss, liability, claim, damage or expense (including the reasonable
cost of investigating or defending any alleged loss, liability, claim, damage,
or expense and reasonable counsel fees incurred in connection therewith),
arising by reason of any person acquiring any Shares, based upon the ground that
the registration statement, Prospectus, shareholder reports or other information
filed or made public by the Fund (as from time to time amended) included an
untrue statement of a material fact or omitted to state a material fact required
to be stated or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading under the 1933 Act
or any other statute or the common law.  However, the Fund does not agree to
indemnify the Distributor or hold it harmless to the extent that the statement
or omission was made in reliance upon, and in conformity with, information
furnished to the Fund by or on behalf of the Distributor.  In no case (i) is the
indemnity of the Fund in favor of the Distributor or any person indemnified to
be deemed to protect the Distributor or any person against any liability to the
Fund or its securityholders to which the Distributor or such person would
otherwise be subject by reason of willful misfeasance, bad faith or gross
negligence in the performance of its duties or by reason of its reckless
disregard of its obligations and duties under this Agreement, or (ii) is the
Fund to be liable under its indemnity agreement contained in this Section with
respect to any claim made against the Distributor or any person indemnified
unless the Distributor or any such person shall have notified the Fund in
writing of the claim within a reasonable time after the summons or other first
written notification giving information of the nature of the claim shall have
been served upon the Distributor or any such person (or after the Distributor or
the person shall have received notice of service on any designated agent).
However, failure to notify the Fund of any claim shall not relieve the Fund from
any liability which it may have to the Distributor or any person against whom
such action is brought otherwise than on account of its indemnity agreement
contained in this paragraph.  The Fund shall be entitled to participate at its
own expense in the defense, or, if it so elects, to assume the defense, of any
suit brought to enforce any claims, but if the Fund elects to assume the
defense, the defense shall be conducted by counsel chosen by it and satisfactory
to the Distributor or person or persons, defendant or defendants in the suit.
In the event the Fund elects to assume the defense of any suit and retain
counsel, the Distributor, officers or trustees or controlling person or persons,
defendant or defendants in the suit, shall bear the fees and expenses of any
additional counsel retained by them. If the Fund does not elect to assume the
defense of any suit, it will reimburse the Distributor, officers or trustees or
controlling person or persons, defendant or defendants in 


                                       5

the suit for the reasonable fees and expenses of any counsel retained by them.
The Fund agrees to notify the Distributor promptly of the commencement of any
litigation or proceedings against it or any of its officers or directors in
connection with the issuance or sale of any of the Shares.

     The Distributor also covenants and agrees that it will indemnify and hold
harmless the Fund and each of its trustees and officers and each person, if any,
who controls the Fund within the meaning of Section 15 of the 1933 Act against
any loss, liability, damage, claim or expense (including the reasonable cost of
investigating or defending any alleged loss, liability, damage, claim or expense
and reasonable counsel fees incurred in connection therewith) arising by reason
of any person acquiring any Shares, based upon the 1933 Act or any other statute
or common law, alleging any wrongful act of the Distributor or any of its
employees or alleging that the registration statement, Prospectus, shareholder
reports or other information filed or made public by the Fund (as from time to
time amended) included an untrue statement of a material fact or omitted to
state a material fact required to be stated or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, insofar as the statement or omission was made in reliance upon,
and in conformity with, information furnished to the Fund by or on behalf of the
Distributor.  In no case (i) is the indemnity of the Distributor in favor of the
Fund or any person indemnified to be deemed to protect the Fund or any such
person against any liability to which the Fund or such person would otherwise be
subject by reason of willful misfeasance, bad faith or gross negligence in the
performance of its duties or by reason of its reckless disregard of its
obligation and duties under this Amended Agreement, or (ii) is the Distributor
to be liable under its indemnity agreement contained in this paragraph with
respect to any claim made against the Fund or any person indemnified unless the
Fund or person, as the case may be, shall have notified the Distributor in
writing of the claim within a reasonable time after the summons or other first
written notification giving information of the nature of the claim shall have
been served upon the Fund or person (or after the Fund or such person shall have
received notice of service on any designated agent).  However, failure to notify
the Distributor of any claim shall not relieve the Distributor from any
liability which it may have to the Fund or any person against whom the action is
brought otherwise than on account of its indemnity agreement contained in this
paragraph.  In the case of any notice to the Distributor, it shall be entitled
to participate, at its own expense, in the defense, or, if it so elects, to
assume the defense, of any suit brought to enforce the claim, but if the
Distributor elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Fund, to its officers and trustees
and to any controlling person or persons, defendant or defendants in the suit.
In the event that the Distributor elects to assume the defense of any suit and
retain counsel, the Fund or controlling persons, defendants in the suit, shall
bear the fees and expenses of any additional counsel retained by them.  If the
Distributor does not elect to assume the defense of any suit, it will reimburse
the Fund, officers and trustees or controlling person or persons, defendant or
defendants in the suit, for the reasonable fees and expenses of any counsel
retained by them.  The Distributor agrees to notify the Fund promptly of the
commencement of any litigation or proceedings against it in connection with the
issue and sale of any of the Shares.

     8.   CONTINUATION, AMENDMENT OR TERMINATION OF THIS AGREEMENT.  This
Agreement shall become effective on the Effective Date and thereafter shall
continue in full force and effect year to year with respect to each class of
Shares so long as such continuance is approved at least annually (i) by the
Board of Trustees of the Fund or by a vote of a majority of the outstanding
voting securities of the respective class of Shares of the Fund, and (ii) by
vote of a majority of the Trustees who are not parties to this Agreement or
interested persons in any such party (the "Independent Trustee") cast in person
at a meeting called for the purpose of voting on such approval, provided,
however, that (a) this Agreement may at any time be terminated with respect to
either class of Shares of the Fund without the payment of any penalty either by
vote of a majority of the Disinterested Trustees, or by vote of a majority of
the outstanding voting securities of the respective class of Shares of the Fund,
on written notice to the Distributor; (b) this Agreement shall immediately
terminate in the event of its assignment; and (c) this Agreement may be
terminated by the Distributor on ninety (90) days' written notice to the Fund.
Upon termination of this Agreement with respect to either class of Shares of the
Fund, the obligations of the parties hereunder shall cease and terminate with
respect to such class of Shares as of the date of such termination, except for
any obligation to respond for a breach of this Agreement committed prior to such
termination.

                                       6
<PAGE>   7
     This Agreement may be amended with respect to either class of Shares at any
time by mutual consent of the parties, provided that such consent on the part of
the Fund shall have been approved (i) by the Board of Trustees of the Fund, or
by a vote of the majority of the outstanding voting securities of the respective
class of Shares of the Fund, and (ii) by vote of a majority of the Independent
Trustees cast in person at a meeting called for the purpose of voting on such
amendment.

     For the purpose of this section, the terms "vote of a majority of the
outstanding voting securities", "interested persons" and "assignment" shall have
the meanings defined in the 1940 Act, as amended.

     9.   LIMITED LIABILITY OF SHAREHOLDER.  Notwithstanding anything to the
contrary contained in this Agreement, you acknowledge and agree that, as
provided by Section 8.1 of the Agreement and Declaration of Trust of the Trust,
this Agreement is executed by the Trustees of the Trust and/or Officers of the
Fund by them not individually but as such Trustees and/or Officers, and the
obligations of the Fund hereunder are not binding upon any of the Trustees,
Officers or Shareholders individually, but bind only the trust estate.

     10.  NOTICE.  Any notice under this Agreement shall be given in writing,
addressed and delivered, or mailed postpaid, to the other party at any office of
such party or at such other address as such party shall have designated in
writing.

     11.  NAME.  In connection with its employment hereunder, the Distributor
hereby agrees and covenants not to change its name without the prior consent of
the Board of Trustees.

     12.  GOVERNING LAW.  THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES HERETO SHALL BE GOVERNED BY, THE
LAW OF THE STATE OF ILLINOIS WITHOUT REFERENCE TO PRINCIPLES OF CONFLICT OF
LAWS.

                     TRANSFER AGENCY AND SERVICE AGREEMENT


     AGREEMENT made as of the 31st day of May, 1997 by and between each of the
VAN KAMPEN AMERICAN CAPITAL OPEN END FUNDS set forth on Schedule "A" hereto,
which are organized under the laws of the state and as the entities set forth
in Schedule "A" hereto (collectively, the "Funds"), and ACCESS INVESTOR
SERVICES, INC., a Delaware corporation ("ACCESS").

                                 R E C I T A L:
                                 -------------

     WHEREAS, each of the Funds desires to appoint ACCESS as its transfer
agent, dividend disbursing agent and shareholder service agent and ACCESS
desires to accept such appointments;

     NOW, THEREFORE, in consideration of the mutual covenants herein contained,
the parties hereto agree as follows:

Article 1. Terms of Appointment; Duties of ACCESS.
           ---------------------------------------

     1.01 Subject to the terms and conditions set forth in this Agreement, each
of the Funds hereby employs and appoints ACCESS as its transfer agent, dividend
disbursing agent and shareholder service agent.

     1.02 ACCESS hereby accepts such employment and appointments and agrees
that on and after the effective date of this Agreement it will act as the
transfer agent, dividend disbursing agent and shareholder service agent for
each of the Funds on the terms and conditions set forth herein.

     1.03 ACCESS agrees that its duties and obligations hereunder will be
performed in a competent, efficient and workmanlike manner with due diligence
in accordance with reasonable industry practice, and that the necessary
facilities, equipment and personnel for such performance will be provided.

     1.04 For a period of one year commencing on the effective date of this
Agreement, ACCESS and each of the Funds agree that the retention of (i) the
chief executive officer, president, chief financial officer, chief operating
officer and secretary of ACCESS and (ii) each director, officer and employee of
ACCESS 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 Funds (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 

<PAGE>   2

of the Funds and the Funds' shareholders. In connection with ACCESS's
acceptance of employment hereunder, ACCESS hereby agrees and covenants for
itself and on behalf of its Affiliates that neither ACCESS 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 Funds
in a timely manner.  In addition, neither ACCESS nor any Affiliate of ACCESS
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 Funds in a timely
manner.

     1.05 In order to assure compliance with section 1.03 and to implement a
cooperative effort to improve and maintain the quality of transfer agency,
dividend disbursing and shareholder services received by each of the Funds and
their shareholders, ACCESS agrees to provide and maintain quantitative
performance objectives, including maximum target turn-around times and maximum
target error rates, for the various services provided hereunder.  ACCESS also
agrees to provide a reporting system designed to provide the Board of Trustees
of each of the Funds (the "Board") on a quarterly basis with quantitative data
comparing actual performance for the period with the performance objectives.
The foregoing procedures are designed to provide a basis for continuing
monitoring by the Board of the quality of services rendered hereunder.

Article 2. Fees and Expenses.
           ------------------

     2.01 For the services to be performed by ACCESS pursuant to this
Agreement, each of the Funds agrees to pay ACCESS the fees provided in the fee
schedules agreed upon from time to time by each of the Funds and ACCESS.

     2.02 In addition to the amounts paid under section 2.01 above, each of the
Funds agrees to reimburse ACCESS promptly for such Fund's reasonable
out-of-pocket expenses or advances paid on its behalf by ACCESS in connection
with its performance under this Agreement for postage, freight, envelopes,
checks, drafts, continuous forms, reports and statements, telephone, telegraph,
costs of outside mailing firms, necessary outside record storage costs, media
for storage of records (e.g., microfilm, microfiche and computer tapes) and
printing costs incurred due to special requirements of such Fund.  In addition,
any other special out-of-pocket expenses paid by ACCESS at the specific request
of any of the Funds will be promptly reimbursed by the requesting Fund.  
Postage for mailings of dividends, proxies, Fund reports and other mailings 

                                   Page 2

to all shareholder accounts shall be advanced to ACCESS by the concerned Fund 
three business days prior to the mailing date of such materials.

Article 3.  Representations and Warranties of Access.
            -----------------------------------------

            ACCESS represents and warrants to each of the Funds that:


     3.01 It is a corporation duly organized and existing and in good standing
under the laws of the State of Delaware.

     3.02 It is duly qualified to carry on its business in each jurisdiction in
which the nature of its business requires it to be so qualified.

     3.03 It is empowered under applicable laws and regulations and by its
charter and bylaws to enter into and perform this Agreement.

     3.04 All requisite corporate proceedings have been taken to authorize it
to enter into and perform this Agreement.

     3.05 It has and will continue to have during the term of this Agreement
access to the necessary facilities, equipment and personnel to perform its
duties and obligations hereunder.

     3.06 It will maintain a system regarding "as of" transactions as follows:

           (a) Each "as of" transaction effected at a price other than that in
      effect on the day of processing for which an estimate has not been given
      to any of the affected Funds and which is necessitated by ACCESS' error,
      or delay for which ACCESS is responsible or which could have been avoided
      through the exercise of reasonable care, will be identified, and the net
      effect of such transactions determined, on a daily basis for each such
      Fund.
           (b) The cumulative net effect of the transactions included in
      paragraph (a) above will be determined each day throughout each month.
      If, on any day during the month, the cumulative net effect upon any Fund
      is negative and exceeds an amount equivalent to  1/2 of 1 cent per share
      of such Fund, ACCESS shall promptly make a payment to such Fund (in cash
      or through use of a credit as described in paragraph (c) below) in such
      amount as necessary to reduce the negative cumulative net effect to less
      than  1/2 of 1 cent per share of such Fund.  If on the last business day
      of the month the cumulative net effect (adjusted by the amount of any
      payments or credits used pursuant to the preceding sentence) upon any
      Fund is negative, such Fund shall be entitled to a reduction in the
      monthly transfer agency fee next payable by an equivalent amount, except
      as provided in paragraph (c) below.  If on the last 

                                   Page 3

<PAGE>   4

      business day of the month the cumulative net effect (similarly adjusted)
      upon any Fund is positive, ACCESS shall be entitled to recover certain
      past payments, credits used and reductions in fees, and to a credit
      against all future payments and fee reductions made under this paragraph  
      to such Fund, as  described in paragraph (c) below.

           (c) At the end of each month, any positive cumulative net effect
      upon any Fund shall be deemed to be a credit to ACCESS which shall first
      be applied to recover any payments, credits used and fee reductions made
      by ACCESS to such Fund under paragraph (b) above during the calendar year
      by increasing the amount of the monthly transfer agency fee next payable
      in an amount equal to prior payments, credits used and fee reductions
      made during such year, but not exceeding the sum of that month's credit
      and credits arising in prior months during such year to the extent such
      prior credits have not previously been utilized as contemplated by this
      paragraph (c).  Any portion of a credit to ACCESS not so used shall
      remain as a credit to be used as payment against the amount of any future
      negative cumulative net effects which would otherwise require a payment,
      use of a credit or fee reduction to such Fund pursuant to paragraph (b)
      above.

Article 4. Representations and Warranties of the Funds.
           --------------------------------------------

           Each of the Funds hereby represents and warrants on behalf of itself
only and not on behalf of any other Funds which are a party to this Agreement 
that:

     4.01 It is duly organized and existing and in good standing under the laws
of the commonwealth or state set forth in Schedule "A" hereto.

     4.02 It is empowered under applicable laws and regulations and by its
Declaration of Trust and by-laws to enter into and perform this Agreement.

     4.03 All requisite proceedings have been taken by its Board to authorize
it to enter into and perform this Agreement.

     4.04 It is an open-end, management investment company registered under the
Investment Company Act of 1940, as amended.

                                   Page 4
<PAGE>   5

     4.05 A registration statement under the Securities Act of 1933, as
amended, is currently effective and will remain effective, and appropriate
state securities laws filings have been made and will continue to be made, with
respect to all of its shares being offered for sale.

Article 5. Indemnification.
           ---------------
     5.01 ACCESS shall not be responsible for and each of the Funds shall
indemnify and hold ACCESS harmless from and against any and all losses,
damages, costs, charges, reasonable counsel fees, payments, expenses and
liabilities (collectively, "Losses") arising out of or attributable to:

           (a) All actions of ACCESS required to be taken by ACCESS for the
      benefit of such Fund pursuant to this Agreement, provided that ACCESS has
      acted in good faith with due diligence and without negligence or willful
      misconduct.

           (b) The reasonable reliance by ACCESS on, or reasonable use by
      ACCESS of, information, records and documents which have been prepared or
      maintained by or on behalf of such Fund or have been furnished to ACCESS
      by or on behalf of such Fund.

           (c) The reasonable reliance by ACCESS on, or the carrying out by
      ACCESS of, any instructions or requests of such Fund.

           (d) The offer or sale of such Fund's shares in violation of any
      requirement under the federal securities laws or regulations or the
      securities laws or regulations of any state or in violation of any stop
      order or other determination or ruling by any federal agency or any state
      with respect to the offer or sale of such shares in such state unless
      such violation results from any failure by ACCESS to comply with written
      instructions of such Fund that no offers or sales of such Fund's shares
      be made in general or to the residents of a particular state.

           (e) Such Fund's refusal or failure to comply with the terms of this
      Agreement, or such Fund's lack of good faith, negligence or willful
      misconduct or the breach of any representation or warranty of such Fund
      hereunder.  Notwithstanding the foregoing, no Fund shall be required to
      indemnify or hold ACCESS harmless from and against any Losses arising out
      of or attributable to any action or failure to take action, or any
      information, records or 

                                   Page 5
<PAGE>   6

      documents prepared or maintained, on behalf of
      the Fund by the Fund's investment adviser or distributor, or any person
      providing fund accounting or legal services to the Fund that is also an
      officer or employee of Van Kampen American Capital, Inc. or its
      subsidiaries unless such person or entity is otherwise entitled to
      indemnification from the Fund.

     5.02 ACCESS shall indemnify and hold harmless each of the Funds from and
against any and all Losses arising out of or attributable to ACCESS' refusal or
failure to comply with the terms of this Agreement, or ACCESS' lack of good
faith, or its negligence or willful misconduct, or the breach of any
representation or warranty of ACCESS hereunder.

     5.03 At any time ACCESS may apply to any authorized officer of any of the
Funds for instructions, and may consult with any of the Funds' legal counsel,
at the expense of such concerned Fund, with respect to any matter arising in
connection with the services to be performed by ACCESS under this Agreement,
and ACCESS shall not be liable and shall be indemnified by such concerned Fund
for any action taken or omitted by it in good faith in reasonable reliance upon
such instructions or upon the opinion of such counsel.  ACCESS shall be
protected and indemnified in acting upon any paper or document reasonably
believed by ACCESS to be genuine and to have been signed by the proper person
or persons and shall not be held to have notice of any change of authority of
any person, until receipt of written notice thereof from the concerned Fund.
ACCESS shall also be protected and indemnified in recognizing stock 
certificates which ACCESS reasonably believes to bear the proper manual or 
facsimile signatures of the officers of the concerned Fund, and the proper 
countersignature of any former transfer agent or registrar, or of a 
co-transfer agent or co-registrar.

     5.04 In the event that any party is unable to perform its obligations
under the terms of this Agreement because of acts of God, strikes, equipment or
transmission failure or damage, or other causes reasonably beyond its control,
such party shall not be liable to the other for any damages resulting from such
failure to perform or otherwise from such causes.

     5.05 In no event and under no circumstances shall any party to this
Agreement be liable to another party for consequential damages under any
provision of this Agreement or for any act or failure to act hereunder.

     5.06 In order that the indemnification provisions contained in this
Article 5 shall apply, upon the assertion of a claim for which one party may be
required to indemnify another, the party seeking indemnification shall promptly
notify the other party of such assertion, and shall keep the other party
advised with respect to all developments concerning such claim.  

                                   Page 6
<PAGE>   7

The party who may be required to indemnify shall have the option to participate
with the party seeking indemnification in the defense of such claim.  The party
seeking indemnification shall in no case confess any claim or make any
compromise in any case in which the other party may be required to indemnify it
except with the other party's prior written consent.

Article 6.  Covenants of Each of the Funds and ACCESS.
            ------------------------------------------
       6.01  Each of the Funds shall promptly furnish to ACCESS the following:

           (a) Certified copies of the resolution of its Board authorizing the
      appointment of ACCESS and the execution and delivery of this Agreement.
           (b) Certified copies of its Declaration of Trust or Articles of
      Incorporation and by-laws and all amendments thereto.

           6.02 ACCESS hereby agrees to maintain facilities and procedures
reasonably acceptable to each of the Funds for safekeeping of share
certificates, check forms and facsimile signature imprinting devices, if any;
and for the preparation or use, and for keeping account of, such        
certificates, forms and devices.

           6.03 ACCESS shall keep records relating to the services to be
performed hereunder in the form and manner as it may deem advisable; provided,
however, that all accounts, books and other records of each of the Funds
(hereinafter referred to as "Fund Records") prepared or maintained by ACCESS
hereunder shall be maintained and kept current in compliance with Section 31 of
the Investment Company Act of 1940 and the Rules thereunder (such Section and
Rules being hereinafter referred to as the "1940 Act Requirements").  To the
extent required by the 1940 Act Requirements, ACCESS agrees that all Fund
Records prepared or maintained by ACCESS hereunder are the property of the
concerned Fund and shall be preserved and made available in accordance with the
1940 Act Requirements, and shall be surrendered promptly to the concerned Fund
on its request.  ACCESS agrees at such reasonable times as may be requested by
the Board and at least quarterly to provide (i) written confirmation to the
Board that all Fund Records are maintained and kept current in accordance with
the 1940 Act Requirements, and (ii) such other reports regarding its
performance hereunder as may be reasonably requested by the Board.

                                   Page 7
<PAGE>   8

           6.04 ACCESS and each of the Funds agree that all books, records,
information and data pertaining to the business of the other party which are
exchanged or received pursuant to the negotiation or the carrying out of this
Agreement shall remain confidential, and shall not be voluntarily       
disclosed to any other person, except as may be required by law.

           6.05 In case of any requests or demands for the inspection of any of
the Fund Records, ACCESS will endeavor to notify each of the concerned
Funds and to secure instructions from an authorized officer of each of the
concerned Funds as to such inspection.  ACCESS reserves the right, however, to
exhibit such Fund Records to any person whenever it is advised by its counsel
that it may be held liable for the failure to exhibit such Fund records to such
person. 

Article 7. Term and Termination Of Agreement.
           ----------------------------------
           7.01 The initial term of this Agreement shall expire May 31, 1999,
and thereafter this Agreement shall automatically be renewed for
successive one year periods to begin on June 1 of each year unless any party
provides notice to the other party at least 120 days in advance of that date
that this Agreement is not to be renewed.

           7.02 Notwithstanding the foregoing, any party may terminate this
Agreement for good and reasonable cause at any time by giving written
notice to the other party at least 60 days prior to the date on which such
termination is to be effective or such shorter period as may be required by
law.

           7.03 Any unpaid fees or reimbursable expenses payable to ACCESS at
the termination date of this Agreement shall be due on that termination date. 
ACCESS agrees to use its best efforts to cooperate with the Funds and the
successor transfer, dividend disbursement, or shareholder servicing agent
or agents in accomplishing an orderly transition.

Article 8. Miscellaneous.
           --------------
          8.01 Except as provided in section 8.03 below, neither this
Agreement nor any rights or obligations hereunder may be assigned by any party
without the written consent of ACCESS or the concerned Fund, as the case may
be; provided, however, that no consent shall be required for any merger of any
of the Funds with, or any sale of all or substantially all the assets of
any of the Funds to, another investment company.


           8.02 This Agreement shall inure to the benefit of and be binding
upon the parties and their respective permitted successors and assigns.

           8.03 ACCESS may, without further consent on the part of any of the
      Funds, subcontract with DST, Inc.,  a Missouri corporation, or any other
      qualified servicer, for the performance of data processing activities;
      provided, however, that ACCESS shall be as fully responsible to each of
      the Funds for the acts and omissions of DST, Inc. or other qualified
      servicer as it is for its own acts and omissions.

           8.04 Without the prior approval of the Boards of Trustees of the
      Funds, ACCESS shall not, directly or indirectly, provide services,
      including services such as transfer agent, dividend disbursing agent or
      shareholder service agent, to any investment companies.

           8.05 This Agreement constitutes the entire agreement between the
      parties hereto with respect to the subject matter hereof, and supersedes
      any prior agreement with respect thereto, whether oral or written, and
      this Agreement may not be modified except by written instrument executed
      by the affected parties.

           8.06 The execution of this Agreement has been authorized by the
      Funds' Trustees. This Plan is executed on behalf of the Funds or the
      Trustees of the Funds as Trustees and not individually and the
      obligations of this Agreement are not binding upon any of the Trustees,
      officers or shareholders of the Funds individually but are binding only
      upon the assets and property of the Funds.  A Certificate of Trust in
      respect of each of the Funds is on file with the appropriate state
      agency.

           8.07 For each of those Funds which have one or more portfolios as
      set forth in Schedule "A" hereto, all obligations of those Funds under
      this Agreement shall apply only on a portfolio-by-portfolio basis and the
      assets of one portfolio shall not be liable for the obligations of any
      other.

           8.08 In the event of a change in the business or regulatory
      environment affecting all or any portion of this Agreement, the parties
      hereto agree to renegotiate such affected portions in good faith.

           8.09 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-law principles thereof) of the State of
      Delaware applicable to contracts made and to be performed in that state.

           8.10 (a) Any dispute, controversy, or claim arising out of or 
           relating to this Agreement, or the breach, termination or validity
           thereof, shall be finally settled by arbitration in accordance with  
           the Expedited Procedures 

                                   Page 9

<PAGE>   10

           of the commercial arbitration Rules of the American Arbitration
           Association (the "AAA") then in effect (the "Rules").  The   
           arbitration shall be held in Chicago, Illinois.

           (b) There shall be one arbitrator who shall be selected jointly by
           the parties.  If the parties are unable to agree on an arbitrator
           within 15 days after a demand for arbitration is made by a party,
           the arbitrator shall be appointed by the AAA in accordance with the
           Rules.  The hearing  shall be held within 90 days of the appointment
           of the arbitrator.  Notwithstanding the Expedited Procedures 
           of the Rules, the arbitrator, at his discretion, may schedule
           additional days of hearings.

           (c) Either party may, without inconsistency with this Agreement,
           seek from a court any interim or provisional relief in aid of
           arbitration, pending the establishment of the arbitral tribunal. 
           The parties hereby submit to the exclusive jurisdiction of the
           federal and state courts located in the northern district of the
           state of Illinois for any such relief in aid of arbitration, or for
           any relief relating to arbitration, except for the enforcement of an
           arbitral award which may be enforced in any court having
           jurisdiction.

           (d) Any arbitration proceedings or award rendered hereunder and the
           validity, effect and interpretation of Section 8.10 shall be
           governed by the Federal Arbitration Act (9 U.S.C. Sections 1 et
                                                                        --
           seq.)  The award shall be final and binding upon the parties. 
           ---
           Judgment upon any award may be entered in any court having
           jurisdiction.

           (e) This Agreement and the rights and obligations of the Parties
           shall remain in full force and effect pending the award in any
           arbitration proceeding hereunder.
