The undersigned, being the Secretary of Van Kampen Trust, a Delaware statutory
trust (the "Trust"), pursuant to the authority conferred upon the Trustees of
the Trust by Section 6.1 of the Trust's Agreement and Declaration of Trust dated
May 10, 1995 (the "Declaration"), and by the affirmative vote of a Majority of
the Trustees does hereby establish and designate as a Series of the Trust, Van
Kampen Inflation-Linked Fixed Income Fund (the "Fund"), with the following
rights, preferences and characteristics:

1. Shares. The beneficial interest in the Fund 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 Fund. 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 Fund shall be divided into four classes
-- Class A, Class B, Class C and Class I. The Trustees shall have the authority
from time to time to authorize additional Classes of Shares of the Fund.

3. Sales Charges. Each Class A, Class B, Class C and Class I 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,  as
amended (the "1940 Act"),  and applicable rules and regulations of the Financial
Industry Regulatory Authority, Inc., all as set forth in the Fund's prospectus.

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





6. Special Meetings. A special meeting of Shareholders of a Class of the Fund
may be called at any time by a Majority of the Trustees 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.

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 Fund 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 Fund outstanding and entitled to
vote or, if such amendment affects the Shares of one or more but not all of the
Classes of the Fund, 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.
