    <footnotes>
        <footnote id="F1">The reported transaction is a distribution by a trust of 2,797 shares of common stock of Research Frontiers Inc. to Robert L. Saxe, the reporting person. Because Robert L. Saxe has a one-half interest as a beneficiary under the trust, Mr. Saxe's direct ownership interest is increasing by the 2,797 shares being distributed to him and Mr. Saxe's indirect ownership is reflected as decreasing by twice this amount to reflect the fact that the trust distributed 2,797 shares of common stock to Robert L. Saxe and 2,797 shares of common stock to the other beneficiary under the trust.</footnote>
