                               AMENDMENT NO. 1 TO
           AMENDED AND RESTATED AGREEMENT AND DECLARATION OF TRUST OF
                      AIM CORE ALLOCATION PORTFOLIO SERIES

          This Amendment No. 1 (the "Amendment") to the Amended and Restated
Agreement and Declaration of Trust of AIM Core Allocation Portfolio Series (the
"Trust") amends, effective as of May 1, 2008, the Amended and Restated Agreement
and Declaration of Trust of the Trust dated as of June 27, 2006, as amended (the
"Agreement").

          Under Section 9.7 of the Agreement, this Amendment may be executed by
a duly authorized officer of the Trust.

          WHEREAS, the Shareholders of the Trust approved this amendment to
eliminate the requirement that shareholders approve the termination of the
Trust, a Fund or share class if there are 100 or more holders of record of the
Trust, Fund or share class;

          NOW, THEREFORE, the Agreement is hereby amended as follows:

     1.   The first paragraph of Section 6.1 of the Agreement is amended and
          restated to read as follows:

          "Section 6.1 Voting Powers. The Shareholders shall have power to vote
          only to: (i) elect Trustees, provided that a meeting of Shareholders
          has been called for that purpose; (ii) remove Trustees, provided that
          a meeting of Shareholders has been called for that purpose; (iii)
          approve the sale of all or substantially all the assets of the Trust
          or any Portfolio or Class, unless the primary purpose of such sale is
          to change the Trust's domicile or form of organization or form of
          statutory trust; (iv) approve the merger or consolidation of the Trust
          or any Portfolio or Class with and into another Company or with and
          into any Portfolio or Class of the Trust, unless (A) the primary
          purpose of such merger or consolidation is to change the Trust's
          domicile or form of organization or form of statutory trust, or (B)
          after giving effect to such merger or consolidation, based on the
          number of Outstanding Shares as of a date selected by the Trustees,
          the Shareholders of the Trust or such Portfolio or Class will have a
          majority of the outstanding shares of the surviving Company or
          Portfolio or Class thereof, as the case may be; (v) approve any
          amendment to this Article VI, Section 6.1; and (vi) approve such
          additional matters as may be required by law or as the Trustees, in
          their sole discretion, shall determine."

     2.   All references in the Agreement to "this Agreement" shall mean the
          Agreement as amended by this Amendment.

     3.   Except as specifically amended by this Amendment, the Agreement is
          hereby confirmed and remains in full force and effect.
