HOUSTON, May 27, 2011 /PRNewswire/ — Gundle/SLT Environmental, Inc. (the “Issuer”) today announced the early settlement of its previously announced tender offer and consent solicitation with respect to any and all of its outstanding $150,000,000 aggregate principal amount of 11% Senior Notes due 2012 (the “Notes”). The tender offer and consent solicitation were subject to certain conditions, including, among others, the receipt of the requisite consents to the supplemental indenture and the receipt by the Issuer of net proceeds from its new senior secured credit facilities (the “Refinancing Transaction”) in an amount sufficient to refinance the Issuer’s existing revolving credit facility, fund all of the Issuer’s obligations under the tender offer and consent solicitation and pay related fees and expenses. As of May 27, 2011, these conditions were satisfied, and the Issuer accepted for purchase the $132,358,000 aggregate principal amount of Notes (representing approximately 88.24% of the outstanding aggregate principal amount of Notes) that had been validly tendered (and not validly withdrawn) as of 5:00 p.m., New York City time, on May 25, 2011 (the “Consent Date”).

The amendments to the indenture governing the Notes contained in the supplemental indenture, dated as of May 25, 2011, became operative immediately prior to the consummation of the Refinancing Transaction. Upon acceptance by the Issuer, all holders who validly tendered (and did not validly withdraw) their Notes on or prior to the Consent Date received $1,003.75 per $1,000 principal amount of such Notes (which consisted of $1,000 as the tender offer consideration and $3.75 as a consent payment). In addition, all such holders received accrued and unpaid interest up to, but not including, May 27, 2011.

The tender offer remains open and is scheduled to expire at 5:00 p.m., New York City time, on June 10, 2011, unless extended or earlier terminated by the Issuer (the “Expiration Date”). Holders of any remaining Notes who validly tender (and do not validly withdraw) their Notes after the Consent Date, but on or prior to the Expiration Date, and whose Notes are accepted for purchase, will receive $1,000 per $1,000 principal amount of such Notes, plus accrued and unpaid interest up to, but not including, the date of payment, payable promptly following the Expiration Date. The Issuer currently expects this payment date will be on or about June 13, 2011. Holders of Notes who tender after the Consent Date will not be entitled to receive a consent payment. Notes tendered after the Consent Date, but on or prior to the Expiration Date, may not be withdrawn, except in limited circumstances where withdrawal rights are required by law.

Any Notes not tendered and purchased pursuant to the tender offer will remain outstanding, and the holders thereof will be bound by the amendments contained in the supplemental indenture even though they have not consented to such amendments. The Issuer intends to redeem any Notes that remain outstanding after the consummation of the tender offer in accordance with the terms of the indenture governing the Notes.
