Those shares of the National Muni Fund would then be distributed pro rata to Arizona Muni Fund&#8217;s shareholders, and the Arizona Muni Fund would subsequently be liquidated and dissolved. Common shares of Arizona Muni Fund would be exchanged for common shares of National Muni Fund based on the relative net asset values of each Fund&#8217;s common shares. These transactions, which are expected to be tax-free, are subject to the approval of the Agreement and Plan of Acquisition by each Fund&#8217;s shareholders (which includes the National Muni Fund
&#8217;s approval of the issuance of new common shares). Any solicitation of proxies by each Fund in connection with this shareholder meeting will be made only pursuant to proxy materials filed under the federal securities laws. It is anticipated that these proxy materials will be distributed to each Fund&#8217;s shareholders in late March or early April 2011. There can be no assurance that the shareholders of each Fund will vote in favor of the proposals.</font></div>
