                                 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 30,918,576 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.),  7 Hanover
Square,  New  York,  New  York  10004  owned  of  record  80.25%  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 02110 or by calling 1-800-426-3750.

         subsidiary  of  Liberty  Financial  (an  intermediate   parent  of  the
         Adviser).

         During the Fund's  fiscal year ended  December 31,  1996,  the Board of
Trustees held seven meetings.

         The Audit  Committee  of the  Colonial  Funds,  consisting  of  Messrs.
Bleasdale,  Ireland,  Lowry,  Moody,  Shinn,  Sullivan and Weeks, met four times
during the Fund's fiscal year ended December 31, 1996. The Committee  recommends
to the Trustees the independent  accountants to serve as auditors,  reviews with
the  independent  accountants  the results of the  auditing  engagement  and the
internal accounting  procedures and controls,  and considers the independence of
the independent accountants, the range of their audit services and their fees.

          The  Compensation  Committee of the Colonial Funds,  consisting of Ms.
     Collins and Messrs.  Neuhauser,  Sullivan  and Weeks,  met twice during the
     Fund's  fiscal  year  ended  December  31,  1996.  The  Committee   reviews
     compensation of the Board of Trustees.

         The Nominating  Committee of the Colonial Funds,  consisting of Messrs.
Bleasdale,  Ireland, Moody and Weeks, did not meet during the Fund's fiscal year
ended December 31, 1996. The Committee in its sole discretion  recommends to the
Trustees  nominees for Trustee and for appointments to various  committees.  The
Committee  will consider  candidates for Trustee  recommended  by  shareholders.
Written  recommendations  with supporting  information should be directed to the
Committee in care of the Fund.

         During the Fund's  fiscal year ended  December  31,  1996,  each of the
current  Trustees,  attended  more  than  75% of the  meetings  of the  Board of
Trustees and the committees of which such Trustee is a member.

         If any of the nominees  listed above becomes  unavailable for election,
the enclosed proxy will be voted for a substitute candidate in the discretion of
the proxy holder(s).

                                  Required Vote

         A  plurality  of  the  votes  cast  at  the  Meeting,  if a  quorum  is
represented, is required for the election of each Trustee.

                           Description of the Adviser

         The  Adviser  is a  wholly-owned  subsidiary  of TCG which in turn is a
wholly-owned  subsidiary of Liberty Financial.  Liberty Financial is an indirect

principal  executive  offices are located at 600  Atlantic  Avenue,  24th Floor,
Boston,  Massachusetts  02210.  Liberty  Mutual is an  underwriter  of  workers'

executive  offices are located at 175  Berkeley  Street,  Boston,  Massachusetts
02117.  Liberty Mutual is deemed to be the controlling entity of the Adviser and
its affiliates.

2.         Ratification of Independent Accountants.

         Price  Waterhouse LLP was selected as independent  accountants  for the
Fund for the Fund's 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  InterMarket  Income Trust I and Colonial  Investment  Grade  Municipal
Trust. 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, required the Fund's Board of 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
("SEC")  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.

      Shareholders are urged to vote, sign and mail their proxies immediately.
