URGENT: PLEASE VOTE YOUR SHARES Dear Stockholders of Seligman Select Municipal Fund, Inc.: A special meeting of stockholders of Seligman Select Municipal Fund, Inc. ("Select") was held on December 18, 2008. At the meeting, stockholders approved a new investment management services agreement between Select and RiverSource Investments, LLC and elected 10 new directors of Select. However, the meeting has been adjourned to 10:00 a.m. on January 16, 2009 in respect of the proposal to approve an Agreement and Plan of Merger and Liquidation (the "Plan), the merger and the other transactions contemplated by the Plan. In connection with the Proxy Statement/Prospectus, dated October 28, 2008, for Select previously mailed to you, your Board of Directors recommends that you vote "FOR" the Plan, Proposal 1 on the enclosed proxy card. If stockholders approve the acquisition of Select by National Municipal Class ("National Fund"), a series of Seligman Municipal Fund Series, Inc. ("SMFS"), at the adjourned special meeting to be held on January 16, 2009, any discount (approximately 9.25% as of December 17, 2008) between the market value of Select's common stock and its net asset value ("NAV") will be eliminated in connection with the conversion and exchange of Select's common stock into Class A common stock of National Fund. National Fund shareholders approved the investment management services agreement between SMFS (on behalf of National Fund) and RiverSource Investments, LLC on November 3, 2008. Although the trading discount of Select's common stock has fluctuated over time, Select's common stock has traded at a discount to its NAV for many years. If the acquisition of Select by National Fund is not approved, it is expected that Select's common stock will continue to trade at a discount to its NAV.
