1. Board Election Proposal. Shareholders of the Funds indicated in Table 1 voted to elect all directors/trustees nominated for election (“Board members”).
2. Charter Amendment Proposal. Shareholders of the Funds indicated in Table 1 approved an amendment to either (i) the Articles of Incorporation of a company (of which the Fund is a series) that is a Minnesota corporation (each a “Company” and collectively, the “Companies”), or (ii) the Declaration of Trust of either RiverSource California Tax Exempt Trust (also a “Company”) or RiverSource Special Tax-Exempt Series Trust (also a “Company”), each a Massachusetts business trust, which provides for an increase in the maximum permissible number of Board members of the Companies from 16 Board

members to 20 Board members. It is expected that, effective June 1, 2011, the Funds (and therefore their respective Companies) that have approved both Proposal 1 (Board Election Proposal) and this Proposal 2 will have a Board comprised of 16 members.
3. Redomiciling Proposal. Shareholders of the Funds indicated in Table 1 approved an Agreement and Plan of Redomiciling, which provides for a change in the domicile and/or form of organization of (i) each Fund that is currently a series of a Company that is organized as a Minnesota corporation, and (ii) Columbia Minnesota Tax-Exempt Fund (which is a series of RiverSource Special Tax-Exempt Series Trust), into new series of RiverSource Series Trust, an existing Massachusetts business trust. The redomicilings are expected to occur on or about March 7, 2011.
4. Investment Management Services Agreement (“IMS Agreement”) Proposal. Shareholders of the Funds indicated in Table 1 approved a new IMS Agreement between the Company, on behalf of the Fund, and Columbia Management Investment Advisers, LLC (“Columbia Management”). The IMS Agreements are designed to achieve consistent investment management service and fee structures across all funds managed by Columbia Management and distributed by Columbia Management Investment Distributors, Inc. (the “Columbia Family of Funds”). Specifically, as further described below, the IMS Agreement approval affects different Funds in different ways:
4a. Terms and Conditions. For the Funds indicated in Column 4a of Table 1, the approved IMS Agreement includes changes to the terms and conditions of the Fund’s IMS Agreement, but neither increases the investment advisory fee rates nor eliminates a performance incentive adjustment (“PIA”) because a PIA does not currently exist for such Funds (“Non-Fee Changes”).
4b. Terms and Conditions / Change in Fee Schedule. For the Funds indicated in Column 4b of Table 1, the approved IMS Agreement includes (i) the Non-Fee Changes and (ii) an increase to the investment advisory fee rates payable to Columbia Management at certain asset levels. Table 2 below outlines the current IMS fee schedule, the new approved IMS fee schedule and the anticipated date on which the new IMS fee schedule will be implemented for these Funds.
4c. Terms and Conditions / Removal of PIA. For the Funds indicated in Column 4c of Table 1, the approved IMS Agreement includes (i) the Non-Fee Changes and (ii) the elimination of the PIA.
4d. Terms and Conditions / Change in Fee Schedule / Removal of PIA. For the Funds indicated in Column 4d of Table 1, the approved IMS Agreement includes (i) the Non-Fee Changes, (ii) an increase to the investment advisory fee rates payable to Columbia Management at all or most asset levels and (iii) the elimination of the PIA. Table 2 below outlines the current IMS fee schedule, the new approved IMS fee schedule and the anticipated date on which the new IMS fee schedule will be implemented for these Funds.

5. Manager of Managers Proposal. Shareholders of the Funds indicated in Table 1 approved a policy authorizing Columbia Management, the Fund’s investment manager, to enter into and materially amend subadvisory agreements in the future, with the approval of the Board, but without obtaining approval from shareholders of such Fund. If there is a hiring of a subadviser in the future for the Fund, within 90 days of such hiring, the Fund will provide shareholders with an information statement that contains substantially the same information about the subadviser, the subadvisory agreement and the subadvisory fee that would otherwise have been required to be sent to shareholders in a proxy statement.
6. Reorganization Proposal. Shareholders of the Funds indicated in Table 1 (each, a “Selling Fund”) approved an Agreement and Plan of Reorganization, which provides for the reorganization of the Selling Fund into another fund in the Columbia Family of Funds (each, a “Buying Fund”). Table 3 below identifies each Selling Fund, its corresponding Buying Fund and the anticipated date on which each reorganization is expected to occur.

In connection with the Fund reorganizations described in 6. Reorganization Proposal above, the following rules and policies will apply:
Restrictions and Other Policies on New Account Openings, Purchases, Exchanges and Redemptions of Selling Fund Shares
New Accounts
New account applications for the purchase of shares of a Selling Fund received in good order will be accepted through the close of business on that Selling Fund’s Reorganization Date, as identified in Table 3. Thereafter, any account application for shares of a Selling Fund will be rejected. Further, any request made to open a new account for shares of a Selling Fund after the close of business on its Reorganization Date will not automatically be treated as a request to open a new account for shares of the corresponding Buying Fund.
Purchases, Exchanges and Redemptions of Shares of a Selling Fund
Purchases, exchanges and redemptions of shares of a Selling Fund will continue to be accepted through the close of business on the Selling Fund’s Reorganization Date, as identified in Table 3. In addition, any request to purchase, exchange or redeem shares of a Selling Fund received within 30 days after the close of business on the Reorganization Date will automatically be treated as a purchase, exchange or redemption (as the case may be) of shares of the corresponding Buying Fund. After this 30-day period, any request to purchase, exchange or redeem shares of a Selling Fund will be rejected and will not automatically be treated as a purchase, exchange or redemption (as the case may be) of shares of the corresponding Buying Fund.
Systematic Investment Plan and Systematic Withdrawal Plan Transactions
If you are currently participating in the Systematic Investment Plan or Systematic Withdrawal Plan with respect to a Selling Fund, your current systematic transactions will be carried over from your Selling Fund to its corresponding Buying Fund.
Important Note
Because each Selling Fund will merge into its corresponding Buying Fund on its Reorganization Date, you should consider the appropriateness of making a new or subsequent investment in the Selling Fund prior to its Reorganization Date. You should consider the investment objectives, risks, charges and expenses of the Buying Fund and/or Selling Fund carefully before investing. To obtain a Buying Fund’s current prospectus, shareholder reports and other regulatory filings, contact your financial advisor or visit www.columbiamanagement.com.
