GEORGE H. GLATFELTER TO RESIGN AS CHAIRMAN OF GLATFELTER

— President and CEO Dante C. Parrini to Become Chairman at 2011 Annual Shareholders’ Meeting —

YORK, Pennsylvania – March 3, 2011 – Glatfelter (NYSE: GLT) today announced that Chairman of the Board George H. Glatfelter II has informed the Board of Directors of his intent to resign as Chairman, effective at the company’s 2011 Annual Meeting of Shareholders on May 4, 2011 and that he will not stand for re-election to the Board in May. This action is part of the company’s previously announced leadership succession plan.

The Board of Directors has unanimously elected Dante C. Parrini as Mr. Glatfelter’s successor as Chairman effective immediately following the Annual Meeting of Shareholders on May 4, 2011, assuming Mr. Parrini is reelected as a director of the Company at that time.

“On behalf of my fellow directors, I wish to thank George for his many and significant contributions to Glatfelter during his 11-year tenure as chairman and 34 years with the company. He has set a high standard for all of us, as we continue to create increasing value for our shareholders,” said Lee C. Stewart, chair of the Nominating and Corporate Governance Committee. “While we will certainly miss George’s unique insight into the industry, the Board has the utmost confidence in Dante’s ability to lead the company into this new era of sustained growth.”

As part of the company’s seamless and orderly leadership succession plan, Mr. Parrini succeeded Mr. Glatfelter as president and chief executive officer on December 31, 2010.
