Item 29. Indemnification.

The Agreement and Declaration of Trust, as amended, filed as Exhibit
(a)(1) and (a)(2) to this Registration Statement provides for
indemnification to each of the Registrant's Trustees and officers
against all liabilities and expenses incurred in acting

C-2
5
as Trustee or officer, except in the case of wilful misfeasance,
bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of such Trustees and officers. The
Underwriting Agreement filed as Exhibit (h) to this Registration
Statement provides for indemnification by the Registrant and
Colonial Management Associates, Inc. (the "Advisor") of Salomon
Smith Barney Inc. (the "Underwriter") and its controlling
persons and by the Underwriter of the Registrant, the Advisor
and their respective Trustees, directors, officers and
controlling persons against certain liabilities, including
liabilities under the Securities Act of 1933, as amended, under
certain circumstances.

Insofar as indemnification for liability arising under the
Securities Act of 1933 may be permitted to trustees, officers
and controlling persons of the Registrant pursuant to the
foregoing provisions, or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities
(other than the payment by the Registrant of expenses incurred
or paid by a trustee, officer or controlling person of the
Registrant in the successful defense of any action, suit or
proceeding) is asserted by such trustee, officer or controlling
person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in
the Act and will be governed by the final adjudication of such
issue.

The Registrant, Colonial Management Associates, Inc. and their
respective trustees, directors and officers are insured by a
directors and officers/errors and omissions liability policy.
