Dear Columbia Fund Shareholder,

At Columbia Management, we periodically evaluate our mutual fund offerings as
part of a broader effort to best address the needs of fund shareholders. As a
result of this review, management has proposed mergers of several of our funds,
including a merger of both Columbia Florida Intermediate Municipal Bond Fund and
Columbia Texas Intermediate Municipal Bond Fund into Columbia Intermediate
Municipal Bond Fund. This proposal has been approved by the funds' Board of
Trustees and is subject to shareholder approval at a special meeting scheduled
for September 6, 2006. A supplement to your prospectus announcing the proposed
merger is enclosed.

In approving the merger, the Trustees of your fund considered, among other
things, overlap in the portfolio management teams (with respect to the Columbia
Florida Intermediate Municipal Bond Fund only), greater diversification of
holdings with little or no loss of state tax benefits (neither Texas nor Florida
has a state personal income tax, although Florida has a general intangibles tax)
and opportunities for expense savings.

As a shareholder of the fund you can expect to receive in July a
prospectus/proxy statement for the shareholder meeting. We urge you to review
that document carefully for details of the proposed merger, and complete and
return your proxy ballot. The merger is expected to be tax-free for federal
income tax purposes.

If approved by shareholders, the merger is tentatively scheduled for mid to late
September 2006; Columbia Florida Intermediate Municipal Bond Fund and Columbia
Texas Intermediate Municipal Bond Fund will remain open for additional purchases
through the close of business on the day of the merger.

We thank you for investing in Columbia Funds and look forward to serving your
investment needs for many years to come. If you have any questions, please
contact your financial advisor or a customer service representative at
800.345.6611.

Sincerely,

/s/ Christopher L. Wilson
