                            PROXY STATEMENT
                         General Information
                                                       April 26, 1996

     The enclosed proxy,  which was first mailed on April 26, 1996, 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 4,  1996,  the Fund had
outstanding 11,509,000 shares of beneficial interest.  Shareholders of record at
the close of  business  on March 4, 1996 will have one vote for each share held.
As of March 4,  1996,  The  Depository  Trust  Company  (Cede & Co.),  7 Hanover
Square,  New  York,  New  York  10004  owned  of  record  76.21%  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 1-800-248-2828.

       1995.  At  December  31,  1995,  Liberty  Newport  was managed by Newport
       Pacific Management,  Inc. and Stein Roe & Farnham  Incorporated,  each an
       affiliate of the Adviser.


     During the  Fund's  fiscal  year  ended  December  31,  1995,  the Board of
Trustees held six meetings.

     The Audit Committee of the Colonial Funds, consisting of Messrs. Bleasdale,
Ireland,  Moody,  Shinn,  Sullivan and Weeks, met twice during the Fund's fiscal
year ended  December  31, 1995.  The  Committee  recommends  to the Trustees the
independent  accountants  to serve as  auditors,  reviews  with the  independent

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 once during  the
Fund's   fiscal  year  ended   December 31,   1995.   The Committee reviews

     The  Nominating  Committee of the  Colonial  Funds,  consisting  of Messrs.

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, 1995, each of the Trustees
attended  more  than  75% of the  meetings  of the  Board  of  Trustees  and the
committees  of which such  Trustee is a member,  except that  Messrs.  Birnbaum,
Grinnell  and  Lowry  attended  more  than 75% of the  meetings  of the Board of
Trustees and committees since they were elected as Trustees on April 21, 1995.

     If any of the nominees listed above becomes  unavailable for election,  the

proxy holder(s).

                            Required Vote

        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

2.      Ratification of Independent Accountants.

     Price  Waterhouse LLP was selected as independent  accountants for the Fund
for the fiscal year ending December 31, 1996, 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  called  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 31,  1996,
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 ("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  Liberty  Mutual and its  affiliates,  which
include  Liberty  Financial,  the Adviser and TCG,  filed a late Form 3 (Initial
Statement of Beneficial Ownership), on which they reported that the Adviser held
14,223.213 shares of the Fund as of March 24, 1995.


              Date for Receipt of Shareholder Proposals
