* Pending shareholder approval.

Q2.   WHY ARE YOU REORGANIZING YOUR MUTUAL FUNDS?
A2.   Our goal at Columbia Management is to provide shareholders with investment
      options that capitalize on the strengths and resources of our individual
      investment advisors.

      The proposed transactions are designed to simplify and strengthen our
      product universe. By reducing product overlap, we expect to help manage
      the costs of our new investment management organization. We also believe
      these transactions align our best investment talent with additional assets
      to manage, and may help to improve the expense ratios charged to
      shareholders, which in turn could help improve returns to shareholders.

Q3.   WHEN WILL THIS REORGANIZATION TAKE EFFECT?
A3.   The proposed transactions have been approved by the target funds' and
      acquiring funds' Trustees and must now be approved by the shareholders of
      the target funds. All of the target funds were closed to new investments
      at the close of business on November 10, 2004. Columbia Management expects
      that the transactions, if approved, will be completed by the end of
      February 2005.

Q4.   WHEN WILL THE PROXY STATEMENTS BE MAILED?
A4.   The proxy statements will begin mailing during the week of January 10,
      2005.

Q5.   WHAT NUMBER CAN I CALL TO VOTE?
A5.   You can call toll-free 1-866-270-3134 for questions and also to vote via a
      live representative. Registered shareholders can also call 866-241-6192 to
      vote via touch-tone phone. Additionally, there are three other ways to
      vote, by mail, fax and via the internet. The toll-free number to vote via
      fax is 888-796-9932, and the address to vote via the internet is
      https://vote.proxy-direct.com.

Q6.   CAN MY FINANCIAL ADVISOR VOTE MY SHARES?
A6.   No. Shares must be voted by using the proxy card that was mailed to the
      shareholder, via telephone or fax or the internet using the unique control
      number printed on the proxy card.  See Q5 directly above for ways to vote.

Q7.   ARE YOU USING A PROXY SOLICITOR?
A7.   Yes. We are using a firm called Alamo Direct who will call clients on our
      behalf to remind them to vote. Shareholders who have sent in their
      completed proxies will not be called.


Q8.   WHY ARE YOU USING A PROXY SOLICITOR?
A8.   A proxy solicitor will assist us in ensuring that as many shareholders as
      possible participate in the vote.

Q9.   AREN'T YOU REALLY DOING THESE MERGERS TO HIDE POOR PERFORMANCE?
A9.   Performance was not the driving factor for our proposals, though we expect
      that these actions could help improve performance. These actions are
      intended to take advantage of our investment talent, and to simplify and
      strengthen our mutual fund product universe. The objective of
      consolidating additional assets under fewer managers is also designed to
      reduce expenses for shareholders. Thus, we believe this is in the
      long-term interest of our shareholders.

Q10.  WHAT IF SHAREHOLDERS DO NOT APPROVE THE PROPOSED MERGERS?
A10.  While we do not expect that to occur, in the event that we do not receive
      shareholder approval, the Board of Trustees of the target fund will
      consider action to take. Such action could include liquidation of your
      fund.

Q11.  WHAT EFFECT WILL THE MERGER HAVE ON MY ACCOUNT BALANCE AND THE VALUE OF MY
      ACCOUNT?
A11.  The value of your account will not change as a result of the merger.
      However, the number of shares you receive of the acquiring fund may be
      different from the number you owned of the target fund, depending on the
      net asset value (NAV) per share of the acquiring fund.

Q12.  WHEN WILL THE MERGER RATIO BE AVAILABLE?
A12.  The merger ratio will be available on the Monday following the merger. It
      will be posted on the Columbia Funds website (www.columbiafunds.com) and
      will be communicated to the back offices of our distribution partners as
      well.

Q13.  WHAT WILL HAPPEN TO THE SECURITIES HELD IN THE TARGET FUNDS?
A13.  They will become part of the acquiring fund's portfolio.

Q14.  WHO WILL MANAGE MY FUND -- THE SAME PERSON/TEAM OR A NEW ONE?
A14.  Currently, the transactions involving the Columbia International Equity
      and Columbia International Stock Funds and the Columbia Growth and
      Columbia Large Cap Growth have the same management teams respectively.
      These teams will continue to manage the combined assets of the respective
      funds after they merge. In the other cases, the manager(s) of the
      acquiring fund will assume responsibility for managing the fund.


            FOR INTERNAL WIM USE ONLY - NOT FOR EXTERNAL DISTRIBUTION




Q15.  WILL THE CUSIP NUMBER/QUOTRON SYMBOL FOR MY FUND CHANGE?
A15.  In all cases, the CUSIP number/QUOTRON symbol of the target funds will
      change to that of the acquiring fund. If a new number or symbol is
      required, then it will be communicated to brokers and shareholders at a
      time closer to the merger.

Q16.  WILL I RECEIVE THE SAME CLASS OF SHARES IN THE COMBINED FUND AS PART OF
      THE MERGER?
A16.  The majority of the fund mergers will be placed in the same class in the
      acquiring fund as maintained in the target fund. There may be some
      instances where the acquiring fund does not offer the same class and in
      this case, a similar class of the fund will be utilized, as described in
      the fund proxy statements. For example, Columbia International Equity Fund
      shareholders invested in the T share class will be placed in the A hare
      class of the International Stock Fund.

Q17.  WHAT ARE THE TAX IMPLICATIONS FOR SHAREHOLDERS?
A17.  We expect each merger to be a non-taxable transaction, and shareholders of
      the funds will not realize any gains or losses as a result of the merger.
      However, these transactions could trigger the funds to pay out dividend
      income and capital gains prior to merging, which may cause a taxable
      distribution for shareholders. We recommend that you review your situation
      with a tax advisor.

Q18.  WILL THERE BE AN INCOME/CAPITAL GAIN DISTRIBUTION?
A18.  There may be a distribution of income and capital gain for the funds as
      required by IRS regulations. If there is a distribution, then it will be
      issued prior to the merger of the respective fund. We will also review
      distributions for the acquiring funds prior to the merger to conform to
      any IRS requirements.

Q19.  CAN I EXCHANGE MY SHARES INTO (OR PURCHASE NEW SHARES OF) THE ACQUIRING
      FUND NOW RATHER THAN WAIT FOR THE MERGER?
A19.  In many cases, yes. You may exchange/purchase shares before the merger if
      the fund you currently own is from the same fund family and if the same
      share class exists in the acquiring fund.
      NOTE: Not all classes of the acquiring funds will be available prior to
      the merger. An exchange is treated as a sale and is considered a taxable
      event, unlike the merger, which is not a taxable event for shareholders.

Q20.  CAN I EXCHANGE MY SHARES INTO ANOTHER COLUMBIA FUNDS FUND RATHER THAN
      HAVING THEM MERGED INTO THE PROPOSED FUND?
A20.  Yes. Columbia Funds has a number of mutual funds available that may be
      suitable for your investment needs. You may exchange to the same share
      class as the fund in which you are currently invested.
      NOTE: An exchange is treated as a sale and is considered a taxable event.
      We recommend that you review your situation with an advisor.


            FOR INTERNAL WIM USE ONLY - NOT FOR EXTERNAL DISTRIBUTION




Q21.  AM I BETTER OFF EXCHANGING NOW OR WAITING FOR THE MERGER?
A21.  This is a personal decision and the outcomes of each will have different
      consequences for you. You have two options:
      1. If you stay in the fund until the merger, the transaction is expected
      to be a nontaxable event, but you may receive an income/capital gain
      distribution;
      2. If you exchange or sell now, the transaction will be a taxable event.
      NOTE: Not all classes of the acquiring funds will be available for
      exchanges prior to the merger. We recommend that you review your situation
      with a tax advisor.

Q22.  IF I EXCHANGE NOW, WILL I BE CHARGED A CDSC ON THIS TRANSACTION?
A22.  All shares exchanged will maintain the appropriate aging schedules and a
      Contingent Deferred Sales Charge (CDSC) may apply on future redemptions,
      as described in the respective fund's prospectus.

Q23.  WHEN I PURCHASED MY COLUMBIA FUND IT WAS CONSIDERED NO-LOAD, NOW THAT FUND
      IS BEING MERGED INTO A DIFFERENT COLUMBIA FUND. DOES THIS MEAN I WILL NOW
      HAVE TO PAY A LOAD FOR THE NEW (ACQUIRING) FUND?
A23.  No. You will be invested into a no-load share class (generally class Z
      shares) of the acquiring fund. You will also be able to continue to
      purchase shares of the fund, or other funds within the fund family, on a
      no-load basis.

Q24.  INSTEAD OF HAVING MY FUND MERGE INTO THE NEW FUND, I WOULD LIKE TO REDEEM
      MY SHARES. WILL I BE CHARGED ANY APPLICABLE CDSC OR WILL IT BE WAIVED?
A24.  You will be charged any applicable CDSC if you liquidate your shares.

Q25.  WILL THERE BE ANY CHANGES IN THE SERVICES ON MY EXISTING ACCOUNT BECAUSE
      OF THE PROPOSED MERGERS?
A25.  There are no plans for changes in services at this time.

Q26.  WHEN WILL I RECEIVE MY NEW ACCOUNT NUMBER?
A26.  At the completion of the merger, you will receive a statement confirming
      the merger transaction, your new account number, the value of the merger
      transaction, and the number of shares acquired in the merger. However, if
      your statement is produced by the Columbia Transfer Agent's group
      retirement plans system, TRAC, then it will not reflect a new account
      number.

Q27.  I HAVE AN AUTOMATIC INVESTMENT (AIP) AND / OR SYSTEMATIC WITHDRAWAL PLAN
      (SWP) WITH ONE OF THE TARGET FUNDS. WILL THAT TRANSFER TO THE ACQUIRING
      FUND?
A27.  Yes. Once the merger is completed, unless you direct Columbia Funds
      Services, Inc. to do otherwise, your automatic investment plan (AIP) and /
      or systematic withdrawal plan (SWP) will continue with the acquiring fund.

Q28.  I AM CURRENTLY RECEIVING AMOUNTS EACH YEAR FROM MY IRA ACCOUNT TO SATISFY
      MY REQUIRED MINIMUM DISTRIBUTION (RMD). WILL THIS AMOUNT AND / OR FEATURE
      BE AFFECTED BY THE MERGER OF MY FUND(S)?


            FOR INTERNAL WIM USE ONLY - NOT FOR EXTERNAL DISTRIBUTION




A28.  No, your RMD calculation will be carried over to the new account and you
      will not experience any interruption of payment.

Q29.  WHAT WILL HAPPEN IF I ALREADY OWN THE ACQUIRING FUND?
A29.  If you currently own the acquiring fund and your registration for both
      funds is the same, then we will combine your shares.

Q30.  DO YOU PLAN ANY FURTHER FUND CONSOLIDATIONS?
A30.  This is the first step in a plan to leverage our assets and to realign the
      most talented people in Columbia Management. We are committed to actively
      managing our products, and we will continue to evaluate our mutual fund
      product lineup and make changes when necessary to strengthen our product
      universe to offer the best possible investments for shareholders. Until
      formal proposals are made to the appropriate Boards of Trustees about any
      future consolidations, it would be premature for us to comment.

Q31.  WHAT IS COLUMBIA MANAGEMENT?
A31.  Columbia Management is the primary investment management division of Bank
      of America Corporation and is among the world's 30 largest asset managers
      with over $300 billion in assets under management as of September 30,
      2004. Columbia Management manages equity, fixed income and cash
      investments for clients ranging from mutual fund shareholders and
      high-net-worth individuals to state pension funds, corporations,
      foundations and other institutional investors. Our ability to serve a wide
      variety of investors, the strong performance of our investment strategies
      and the sharp focus we maintain on the needs of our clients has made
      Columbia Management a formidable force within the asset management arena.
