Glatfelter Announces Amendment of Revolving Credit Agreement

and Early Redemption of its $100 million Notes

YORK, Pennsylvania – November 21, 2011 – Glatfelter (NYSE: GLT) today announced an amendment to its existing revolving credit agreement, which increased the size, modified the fee and interest structure, and extended the maturity.

The amendment increased the company’s revolving credit facility from $225 million to $350 million with a $100 million accordion feature, extended the term through November 2016, and provides a more favorable pricing grid. The company will use the facility to retire in December its $100 million 7 ¹/8% Notes due May 2016, and for working capital purposes, growth initiatives, and other general corporate purposes. The company expects to record an after-tax charge of $6.3 million in the fourth quarter related to the Note redemption.

Dante C. Parrini, Chairman and Chief Executive Officer, said, “We are very pleased with the amendment to our bank facility. The retirement of the $100 million Notes will create immediate savings and has a quick payback and the increased size and extended term will allow us to continue to execute our plans for investing in our businesses and for pursuing acquisitions.”
