        <footnote id="F1">The reporting person is a trustee of the Irrevocable Trust of George H. Glatfelter dated 10/19/76 (the &quot;1976 Trust&quot;) and disclaims beneficial ownership of the reported securities of P. H. Glatfelter Company (the &quot;Company&quot;).</footnote>
        <footnote id="F2">On December 18, 2009, the reporting person filed a Form 4 to report transactions by the 1976 Trust that occurred between August 22, 2008 and November 4, 2008. The sales report furnished by the administator of the 1976 Trust to the reporing person, which was subsequently used in the preparation of the Form 4, contained a typographical error and indicated that 33,000 shares of Company common stock were sold on August 28, 2008, when in fact, 33,300 shares of Company stock were sold on that date. This Form 4/A is being filed to accurately reflect that sale. As of November 4, 2008, the date of the last transaction reported on the Form 4 filed on December 18, 2009, the reporting person was the direct beneficial owner of 68,397 shares of Company common stock, the indirect owner of 4,410 shares of Company common stock held through the Company's 401(k) plan, and the indirect owner of 140,000 shares of Company common stock held by the 1976 Trust.</footnote>
