                       BLACKROCK MUNICIPAL INCOME TRUST

                                 AMENDMENT TO
                          STATEMENT OF PREFERENCES OF
           VARIABLE RATE MUNI TERM PREFERRED SHARES ("VMTP SHARES")
                            DATED DECEMBER 15, 2011
                       (THE "STATEMENT OF PREFERENCES")

   The undersigned officer of BlackRock Municipal Income Trust (the "Trust"), a
Delaware statutory trust, hereby certifies as follows:

   1. The Board of Trustees of the Trust (with the consent of the Holders (as
defined in the Statement of Preferences) of the VMTP Shares required under
Section 5 of the Statement of Preferences) has adopted resolutions to amend the
Statement of Preferences as follows:

   The Statement of Preferences of the Trust is hereby amended by deleting
Section 10(b)(i)(A) and replacing it with the following:

   (i) (A) TERM REDEMPTION. The Trust shall redeem, out of funds legally
available therefor and otherwise in accordance with Applicable Law, all
Outstanding VMTP Preferred Shares on the Term Redemption Date at the Redemption
Price; provided, however, the Trust shall have the right, exercisable at any
time no earlier than 9 months prior to the Term Redemption Date, to request
that the Total Holders extend the term of the Term Redemption Date for an
additional period as may be agreed upon by the Trust and the Total Holders,
which request may conditioned upon terms and conditions that are different from
the terms and conditions herein. Each Holder shall, no later than the deadline
specified in such request, which shall not be less than 30 days after such
Holder's receipt of such request unless otherwise agreed to by such Holder,
notify the Trust of its acceptance or rejection of such request, which
acceptance by any such Holder may be a Conditional Acceptance conditioned upon
terms and conditions which are different from the terms and conditions herein
or the terms and conditions proposed by the Trust in making an extension
request. If any Holder fails to notify the Trust of its acceptance or rejection
of the Trust's request for extension by the deadline specified in such request,
the Trust may either deem such failure to respond as a rejection of such
request or extend the deadline for such request with respect to such Holder,
provided, however, in all cases any acceptance by a Holder of a request to
extend, if any, shall be made pursuant to an affirmative written acceptance by
the Total Holders. If the Total Holders (or any thereof) provide a Conditional
Acceptance, then the Trust shall, no later than the deadline specified in the
Conditional Acceptance, which shall not be less than 30 days after the Trust's
receipt of the Conditional Acceptance unless otherwise agreed to by the Trust,
notify the Total Holders of its acceptance or rejection of the terms and
conditions specified in the Conditional Acceptance. If the Trust fails to
notify the Total Holders by the deadline specified in the Conditional
Acceptance, the Total Holders may either deem such failure to respond as a
rejection of the terms and conditions specified in the Conditional Acceptance
or extend the deadline for such response by the Trust, provided, however, in
all cases any acceptance by a Holder of a request to extend, if any, shall be
made pursuant to an affirmative written acceptance by the Total Holders. Each
Holder may grant or deny any request for extension of the Term Redemption Date
in its sole and absolute discretion.



   2. Except as amended hereby, the Statement of Preferences remains in full
force and effect.

   3. A copy of this amendment shall be lodged with the records of the Trust
and filed in such places as the Trustees deem appropriate.

                           [Signature Page Follows]
