        <footnote id="F1">Represents 1 share subscribed for by the Reporting Person pursuant to an over-subscription priviledge under the rights offering referenced herein. Shareholders as of the rights offering's record date (the &quot;Record Date Shareholders&quot;) who exercised all rights issued to them were entitled to subscribe for additional common shares at the subscription price.  If sufficent common shares are not available to honor all over-subscription requests available common shares will be allocated pro rata among the Record Date shareholders who over-subscribe, based on the number of rights issued to them by the Issuer on the record date.</footnote>
        <footnote id="F2">The transferable rights offering commenced on September 13, 2010 and expired on October 15, 2010. The subscription price was $2.72 per share and was determined based upon a formula equal to 92.5% of the average of the last reported sales price of the Fund's common shares on the NYSE Amex on the expiration date and each of the four preceding trading days.</footnote>
        <footnote id="F3">The subscription rights entitle the holder to purchase one new common share for every three rights held (1-for-3).</footnote>
