COLONIAL INVESTMENT GRADE MUNICIPAL TRUST
One Financial Center
Boston, Massachusetts 02111
April 23, 1999
Dear Shareholder:
You recently received a proxy statement requesting your vote on important
proposals. Our records show that we have not received your completed ballot. The
Colonial Investment Grade Municipal Trust's Annual Meeting of Shareholder was
adjourned on April 15, 1999 with respect to one of the proposals. The Fund did
not receive enough votes to approve this proposal, although the majority of
shareholders voting were in favor. The adjourned meeting will be held on May 20,
1999, and it is important that we receive your vote before this meeting to avoid
the continued expense of additional solicitations for this proposal. Please cast
your ballot. We have included another copy of the proxy ballot and a business
reply envelope for your convenience.
Colonial Management and the Trustees believe that the proposal to permit the
issuance of preferred shares is in the best interests of shareholders because
this may result in an increase in net income available to holders of common
shares.
In closing, we ask you to review the proxy statement and consider the proposal
carefully. Thank you for your assistance.
Sincerely,
Stephen E. Gibson
President
