COLONIAL INVESTMENT GRADE MUNICIPAL TRUST
One Financial Center

May 11, 1999
Dear Shareholder:
You recently received a proxy statement and ballot 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
Shareholders has been adjourned for 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.
To make voting faster and more convenient for you, we have arranged for you to
vote by telephone, if you prefer. However, if you choose to vote by telephone,
please do not mail the enclosed proxy ballot. The enclosed materials provide a
toll-free telephone number and instructions on voting by telephone.
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
