Investment Advisory Agreement Approval

Both the Investment Company Act of 1940 and the terms of the Fund's investment
advisory agreement require that the investment advisory agreement between the
Fund and its investment adviser be approved annually both by a majority of the
Board of Managing General Partners and by a majority of the independent Managing
General Partners voting separately.

On May 25, 2005, the Board of Managing General Partners, and the independent
Managing General Partners voting separately, determined that the terms of the
investment advisory agreement are fair and reasonable and approved the
continuance of the investment advisory contract as being in the best interests
of the Fund and its shareholders. In making its determination, the Board of
Managing General Partners considered materials that were specifically prepared
by the investment adviser at the request of the Board and Fund counsel, and by
an independent provider of investment company data contracted to assist the
Board, relating to the contract review process. The Board also considered
information received periodically about the portfolio, performance, the
investment strategy, portfolio management team and fees and expenses of the
Fund. Finally, the Board considered materials it had received in approving a
change in the advisory fee rate effective November 1, 2004. The Board of
Managing General Partners considered the contract over a period of several
months and the non-management Managing General Partners held sessions both with
the investment adviser and separate from the investment adviser in reviewing and
considering the contract.

In approving the investment advisory agreement, the Board of Managing General
Partners considered, among other things, the nature, extent and quality of the
services provided by the investment adviser, the performance, fees and expenses
of the Fund compared to other similar funds and other products, the investment
adviser's expenses in providing the services and the profitability of the
investment adviser and its affiliated companies. The Board of Managing General
Partners considered the extent to which any economies of scale experienced by
the investment adviser are shared with the Fund's shareholders, and the
propriety of breakpoints in the Fund's investment advisory fee schedule. The
Board of Managing General Partners considered comparative advisory fees of the
Fund and other investment companies and/or other products at different asset
levels, and considered the trends in the industry. The Board of Managing General
Partners also reviewed the benefit to the investment adviser of receiving
research paid for by Fund assets and the propriety of such arrangements. The
Board of Managing General Partners evaluated other benefits the investment
adviser and its affiliates derive from their relationship with the Fund. The
Board of Managing General Partners reviewed information about the foregoing
factors and considered changes, if any, in such information since its previous
approval. The Board of Managing General Partners discussed the financial
strength of the investment adviser and its affiliated companies and the
capability of the personnel of the investment adviser, and specifically the
strength and

 2


background of its portfolio management personnel. The Board of Managing General
Partners reviewed the statutory and regulatory requirements for approval and
disclosure of investment advisory agreements.

The Board of Managing General Partners, including the independent Managing
General Partners, evaluated all of the foregoing and does not believe any single
factor or group of factors control or dominate the review process, and, after
considering all factors together, has determined, in the exercise of its
business judgment, that approval of the investment advisory agreement is in the
best interests of the Fund and its shareholders. The following summary provides
more detail on certain matters considered but does not detail all matters
considered.

Nature, Extent and Quality of the Services Provided. On a regular basis, the
Board of Managing General Partners considers the roles and responsibilities of
the investment adviser as a whole and for those specific portfolio management,
support and trading functions servicing the Fund. The Managing General Partners
discuss with investment adviser the resources available and used in managing the
Fund. The Fund discloses information about its portfolio management team members
and their experience in its prospectus. The Managing General Partners also
discuss certain other services which are provided on a cost-reimbursement basis
by the investment adviser or its affiliates to the Van Kampen funds including
certain accounting, administrative and legal services. The Board has determined
that the nature, extent and quality of the services provided by the investment
adviser support its decision to approve the investment advisory contract.

Performance, Fees and Expenses of the Fund. On a regular basis, the Board of
Managing General Partners reviews the performance, fees and expenses of the Fund
compared to its peers and to appropriate benchmarks. In addition, a performance
committee of the Board spends more focused time on the performance of the Fund
and other funds in the Van Kampen complex, paying specific attention to
underperforming funds. The Managing General Partners discuss with the investment
adviser the performance goals and the actual results achieved in managing the
Fund. When considering a fund's performance, the Managing General Partners and
the investment adviser place emphasis on trends and longer-term returns
(focusing on one-year, three-year and five-year performance with special
attention to three-year performance) and, when a fund's weighted performance is
under the fund's benchmark, they discuss the causes and where necessary seek to
make specific changes to investment strategy or investment personnel. The Fund
discloses more information about its performance elsewhere in this report and in
the Fund's prospectus. The Managing General Partners discuss with the investment
adviser the level of advisory fees for this Fund relative to comparable funds
and other products advised by the adviser and others in the marketplace. The
Managing General Partners review not only the advisory fees but other fees and
expenses (whether paid to the adviser, its affiliates or others) and the Fund's
overall expense ratio.

                                                                               3


The Board has determined that the performance, fees and expenses of the Fund
support its decision to approve the investment advisory contract.

Investment Adviser's Expenses in Providing the Service and Profitability. At
least annually, the Managing General Partners review the investment adviser's
expenses in providing services to the Fund and other funds advised by the
investment adviser and the profitability of the investment adviser. These
profitability reports are put together by the investment adviser with the
oversight of a special ad hoc committee of the Board. The Managing General
Partners discuss with the investment adviser its revenues and expenses,
including among other things, revenues for advisory services, portfolio
management-related expenses, revenue sharing arrangement costs and allocated
expenses both on an aggregate basis and per fund. The Board has determined that
the analysis of the investment adviser's expenses and profitability support its
decision to approve the investment advisory contract.

Economies of Scale. On a regular basis, the Board of Managing General Partners
considers the size of the Fund and how that relates to the Fund's expense ratio
and particularly the Fund's advisory fee rate. In conjunction with its review of
the investment adviser's profitability, the Managing General Partners discuss
with the investment adviser how more (or less) assets can affect the efficiency
or effectiveness of managing the Fund's portfolio and whether the advisory fee
level is appropriate relative to current asset levels and/or whether the
advisory fee structure reflects economies of scale as asset levels change. The
Board has determined that its review of the actual and potential economies of
scale of the Fund support its decision to approve the investment advisory
contract.

Other Benefits of the Relationship. On a regular basis, the Board of Managing
General Partners considers other benefits to the investment adviser and it
affiliates derived from its relationship with the Fund and other funds advised
by the investment adviser. These benefits include, among other things, fees for
transfer agency services provided to the funds, in certain cases research
received by the adviser generated from commission dollars spent on funds'
portfolio trading, and in certain cases distribution or service related fees
related to funds' sales. The Managing General Partners review with the
investment adviser each of these arrangements and the reasonableness of its
costs relative to the services performed. The Board has determined that the
other benefits received by the investment adviser or its affiliates support its
decision to approve the investment advisory contract.

VAN KAMPEN EXCHANGE FUND

NOTES TO FINANCIAL STATEMENTS -- JUNE 30, 2005 (UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Exchange Fund (the "Fund"), a California limited partnership, is a
partnership registered under the Investment Company Act of 1940, as amended, as
a diversified, open-end investment management company. The Fund seeks long-term
growth of capital. The production of current income is a secondary objective.
The Fund commenced investment operations on December 16, 1976.

    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 accounting principles
generally accepted in the United States of America 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 last sale price as of the close of such securities exchange.
Equity securities traded on NASDAQ are valued at the NASDAQ Official Closing
Price. Listed and unlisted securities for which the last sales price is not
available are valued at the mean between the last reported bid and ask price.
For those securities where quotations or prices are not available, valuations
are determined in accordance with procedures established in good faith by the
Managing General Partners. Short-term securities with remaining maturities of 60
days or less are valued at amortized cost, which approximates market value.

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 whereby 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 Asset Management (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. INVESTMENT INCOME Dividend income is recorded on the ex-dividend date and
interest income is recorded on an accrual basis.

D. FEDERAL INCOME TAXES The Fund has met the qualifications to be classified as
a partnership for federal income tax purposes and intends to maintain this
qualification in the future. A partnership is not subject to federal income tax.

</Table>

E. DISTRIBUTION OF INCOME AND GAINS Quarterly distributions to partners are
recorded on the record date. Net investment income is allocated daily to each
partner, relative to the total number of units held. Capital gains or losses
will be allocated equally among units outstanding on the day recognized.

F. EXPENSE REDUCTIONS During the six months ended June 30, 2005, the Fund's
custody fee was reduced by $1,014 as a result of credits earned on cash
balances.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, the Adviser will
provide facilities and investment advice to the Fund for an annual fee payable
monthly of .30% based on the average daily net assets of the Fund.

    For the six months ended June 30, 2005, the Fund recognized expenses of
approximately $3,500 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to the Fund, of which a trustee of the Fund
is a partner of such firm and he and his law firm provide legal services as
legal counsel to the Fund.

    Under separate Accounting Services and Chief Compliance Officer ("CCO")
Employment agreements, the Adviser provides accounting services and the CCO
provides compliance services to the Fund. The costs of these services are
allocated to each fund. For the six months ended June 30, 2005, the Fund
recognized expenses of approximately $4,400 representing Van Kampen Investments
Inc.'s or its affiliates' (collectively "Van Kampen") cost of providing
accounting services to the Fund, as well as, the salary, benefits and related
costs of the CCO and related support staff paid by Van Kampen. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Other" expenses in the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the six months ended
June 30, 2005, the Fund recognized expenses of approximately $7,400 representing
transfer agency fees paid to VKIS. Transfer agency fees are determined through
negotiations with the Fund's Managing General Partners.

    Managing general partners of the Fund who are not affiliated with the
Adviser are compensated by the Fund at the annual rate of approximately $500
plus a fee of $250 per Board meeting attended.

    The Managing General Partners of the Fund instituted a Retirement Plan
effective April 1, 1996. The Plan is not funded, and obligations under the Plan
will be paid solely out of the Fund's general accounts. The Fund will not
reserve or set aside funds for the payment of its obligations under the Plan by
any form of trust or escrow. For the current Managing General Partners not
affiliated with the Adviser, the annual retirement benefit payable per

                                                                              13


VAN KAMPEN EXCHANGE FUND

NOTES TO FINANCIAL STATEMENTS -- JUNE 30, 2005 (UNAUDITED) continued

year for a ten year period is based upon the highest total annual compensation
received in any of the three calendar years preceding retirement. Managing
General Partners with more than five but less than ten years of service at
retirement will receive a prorated reduced benefit. Under the Plan, for the
Managing General Partners retiring with the effectiveness of the Plan, the
annual retirement benefit payable per year for a ten year period is equal to 75%
of the total compensation received from the Fund during the 1995 calendar year.

    At June 30, 2005, Van Kampen Funds Inc. and Van Kampen Exchange Corp., as
nonmanaging general partners of the Fund, owned 223 and 3,129 units of
partnership interest, respectively.

3. PARTNERSHIP UNIT TRANSACTIONS

Partners of the Fund may redeem units at any time. The net asset value of units
redeemed, other than redemptions under a systematic withdrawal plan, may be paid
in cash or securities, at the option of the Fund, and will ordinarily be paid in
whole or in part in securities. The Fund's valuation will determine the quantity
of securities tendered. The Fund will select securities for tender in
redemptions based on tax or investment considerations.

4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $-0- and $589,180, respectively.

6. INDEMNIFICATIONS
