Ratify or reject the selection of independent accountants; and 3. Transact such other business as may properly come before the Meeting or any adjournment thereof. By order of the Trustees, Arthur O. Stern, Secretary April 24, 1997 NOTICE: YOUR VOTE IS IMPORTANT, REGARDLESS OF THE NUMBER OF SHARES YOU OWN. IF A QUORUM IS NOT PRESENT AT THE MEETING, ADDITIONAL EXPENSES WILL BE INCURRED TO SOLICIT ADDITIONAL PROXIES. TO AVOID THESE COSTS TO YOUR FUND, PLEASE VOTE, SIGN AND RETURN YOUR PROXY IN THE ENCLOSED POSTAGE-PAID ENVELOPE IMMEDIATELY. IG-85/558D-0497 1007-PS-97 PROXY STATEMENT General Information April 24, 1997 The enclosed proxy, which was first mailed on April 24, 1997, is solicited by the Trustees for use at the Meeting. All properly executed proxies received in time for the Meeting will be voted as specified in the proxy or, if no specification is made, in favor of each proposal referred to in the Proxy Statement. The proxy may be revoked prior to its exercise by a later dated proxy, by written revocation received by the Secretary or by voting in person. Solicitation may be made by mail, telephone, telegraph, telecopy and personal interviews. Authorization to execute proxies may be obtained by telephonically or electronically transmitted instructions. The cost of solicitation will be paid by the Fund. Holders of a majority of the shares outstanding and entitled to vote constitute a quorum and must be present in person or represented by proxy for business to be transacted at the Meeting. On March 3, 1997, the Fund had outstanding 11,509,000 shares of beneficial interest. Shareholders of record at the close of business on March 3, 1997 will have one vote for each share held. As of March 3, 1997, The Depository Trust Company (Cede & Co.), P.O. Box 20, New York, New York 10274 owned of record 77.83% of the Fund's outstanding shares. Votes cast by proxy or in person will be counted by persons appointed by the Fund to act as election tellers for the Meeting. The tellers will count the total number of votes cast "for" approval of the proposals for purposes of determining whether sufficient affirmative votes have been cast. Where a shareholder withholds authority or abstains, or the proxy reflects a "broker non-vote" (i.e., shares held by brokers or nominees as to which (i) instructions have not been received from the beneficial owners or persons entitled to vote and (ii) the broker or nominee does not have discretionary voting power on a particular matter), the shares will be counted as present and entitled to vote for purposes of determining the presence of a quorum. With respect to the election of Trustees and ratification of independent accountants, withheld authority, abstentions and broker non-votes have no effect on the outcome of the voting. Further information concerning the Fund is contained in its most recent Annual Report to shareholders, which is obtainable free of charge by writing the Adviser at One Financial Center, Boston, MA 02111 or by calling 1-800-426-3750. 1.

Price Waterhouse LLP was selected as independent accountants for the Fund for the fiscal year ending December 31, 1997, by unanimous vote of the Trustees, subject to ratification or rejection by the shareholders. Neither Price Waterhouse LLP nor any of its partners has any direct or material indirect financial interest in the Fund. A representative of Price Waterhouse LLP will be available at the Meeting, if requested by a shareholder in writing at least five days before the Meeting, to respond to appropriate questions and make a statement (if the representative desires). Required Vote Ratification requires the affirmative vote of a majority of the shares of the Fund voted at the Meeting. 3. Other Matters and Discretion of Attorneys Named in the Proxy As of the date of this Proxy Statement, only the business mentioned in Items 1 and 2 of the Notice of the Meeting is contemplated to be presented. If any procedural or other matters properly come before the Meeting, the enclosed proxy shall be voted in accordance with the best judgment of the proxy holder(s). The Meeting is to be held at the same time as meetings of the shareholders of Colonial High Income Municipal Trust and Colonial InterMarket Income Trust I. It is anticipated that the meetings will be held simultaneously. In the event that any Fund shareholder at the Meeting objects to the holding of a simultaneous meeting and moves for an adjournment of the meetings so that the Meeting of the Fund may be held separately, the persons named as proxies will vote in favor of such an adjournment. If a quorum of shareholders (a majority of the shares entitled to vote at the Meeting) is not represented at the Meeting or at any adjournment thereof, or, even though a quorum is so represented, if sufficient votes in favor of the Items set forth in the Notice of the Meeting are not received by May 30, 1997, the persons named as proxies may propose one or more adjournments of the Meeting for a period or periods of not more than ninety days in the aggregate and further solicitation of proxies may be made. Any such adjournment may be effected by a majority of the votes properly cast in person or by proxy on the question at the session of the Meeting to be adjourned. The persons named as proxies will vote in favor of such adjournment those proxies which they are entitled to vote in favor of the Items set forth in the Notice of the Meeting. They will vote against any such adjournment those proxies required to be voted against any of such Items. Compliance with Section 16(a) of the Securities Exchange Act of 1934 Section 16(a) of the Securities Exchange Act of 1934, as amended, and Section 30(f) of the 1940 Act, as amended, require the Fund's Trustees and executive officers, persons who own more than ten percent of the Fund's equity securities, the Fund's investment adviser and affiliated persons of the Fund's investment adviser, to file with the Securities and Exchange Commission initial reports of ownership and reports of changes in ownership of the Fund's shares and to furnish the Fund with copies of all Section 16(a) forms they file. Based solely upon a review of copies of such filings that were so furnished to the Fund, the Fund believes that Stephen E. Gibson, a Director and the President and Chief Executive Officer of the Adviser and TCG, filed a late Form 3 (Initial Statement of Beneficial Ownership), on which he reported no holdings of the Fund. Date for Receipt of Shareholder Proposals Proposals of shareholders which are intended to be considered for inclusion in the Fund's proxy statement relating to the 1998 Annual Meeting of Shareholders of the Fund must be received by the Fund at One Financial Center, Boston, Massachusetts 02111 on or before December 26, 1997.
