To be Effective April 1, 2011

                      AMENDMENT TO DECLARATION OF TRUST OF
                  INVESCO MUNICIPAL INCOME OPPORTUNITIES TRUST

          WHEREAS Invesco Municipal Income Opportunities Trust (the "Trust") was
established by the Declaration of Trust dated June 21, 1988, as amended from
time to time (the "Declaration") under the laws of the Commonwealth of
Massachusetts;

          WHEREAS Section 8.3 of the Declaration provides that the Trustees may
amend the Declaration without the vote or consent of Shareholders for any
purpose that does not adversely affect the rights of any Shareholder with
respect to which the amendment is or purports to be applicable; and

          WHEREAS the Trustees of the Trust have deemed it advisable to decrease
the maximum number of Trustees provided for under the Declaration.

NOW THEREFORE

          1.    Section 2.1 of Article II of the Declaration is hereby amended
so that such Section shall read in its entirety as follows

     Section 2.1. Number of Trustees. The number of Trustees shall be such
     number as shall be fixed from time to time by written instrument
     signed by a majority of the Trustees provided however that the number
     of Trustees shall in no event be less than three nor more than sixteen
     except as such number shall be increased in connection with the rights
     of the holders of the Preferred Shares to elect a majority of the
     Trustees as provided in Section 6.1 hereof. No reduction in the number
     of Trustees shall have the effect of removing any Trustee from office
     prior to the expiration of his term unless the Trustee is specifically
     removed pursuant to Section 2.2 of this Article II at the time of
     decrease.

          2.    All capitalized terms are used herein as defined in the
Declaration unless otherwise defined herein. All references in the Declaration
to "this Declaration" shall mean the Declaration as amended by this Amendment.

          3.    The Trustees of the Trust hereby reaffirm the Declaration as
amended in all respects.

          4.    The undersigned hereby certify that this instrument has been
duly adopted in accordance with the provisions of the Declaration.

         6.     This amendment may be executed in more than one counterpart
each of which shall be deemed an original, but all of which together shall
constitute one and the same document.

         IN WITNESS WHEREOF the undersigned Trustees of the Trust have executed
this instrument this 31st day of March 2011.
