Tembec to Idle its Coated Paper Mill in St. Francisville, Louisiana

Temiscaming, Quebec, Canada, 01 June 2007 – Tembec today announced that its coated paper mill located in St. Francisville, Louisiana, will be indefinitely idled, with a target date for idling of 31 July 2007. It will affect approximately 540 employees.

The St. Francisville mill has a capacity of 325,000 short tons of coated and specialty papers, primarily used in catalogues, magazines, and cover stock. Tembec acquired the facility in June 2001 by way of a Chapter 11 bankruptcy proceeding involving the mill’s former owner, Crown Paper Co.

A number of factors have combined to make this decision necessary, according to Dan Alexander, executive vice president and president, Paper Group. “The effect of challenging market conditions in terms of both price and demand, the inconsistent performance of the mill in terms of production, the increased cost of purchased energy, and the high manufacturing costs at this site have resulted in a situation that could not be sustained. While there has been progress during the past year, the overall financial performance of this site has been and continues to be unacceptable,” said Alexander.

The decision to idle St. Francisville is consistent with the recovery plan that was announced last year by James Lopez, Tembec president and CEO. Margin improvement at all manufacturing locations is central to this plan and the company had indicated that, where no long-term solutions could be identified and implemented to achieve this goal, necessary action would be taken.

“Significant steps were taken in 2006 to lower the operating costs of this facility and upgrade the product mix. Despite these changes, this facility continues to be hampered by high energy costs, low machine productivity and difficult market conditions. The company will continue to evaluate options to improve the profitability of this site and will take all available steps to ensure its customers will not experience supply interruptions,” said Lopez.

Tembec indicated that it is reviewing the full range of alternatives for this site. The company would not speculate on the outcome of this review process.

“Decisions of this nature are never easy to make, and Tembec regrets the impact of today’s announcement on employees, their families and the St. Francisville community,” concluded Alexander.
