PORTLAND, Ore--(BUSINESS WIRE)--June 27, 2000

Louisiana-Pacific Corporation (NYSE:LPX) announced today that Colin Watson, CEO of Spar Aerospace, and Gary Cook, former CEO of Witco Chemicals have been elected to its Board of Directors beginning Tuesday, June 27, 2000.

Colin Watson serves as CEO of Spar Aerospace Limited in Toronto, Ontario, Canada and is currently on the board of Rogers Cablesystems Ltd., where he formally served as CEO.

"Colin's strong operating background and perspective of doing business in Canada will be valuable in helping us direct our growing presence in that country," said Mark A. Suwyn, Louisiana-Pacific chairman and CEO. "I look forward to his contributions as we work to profitably grow the company."

As former CEO of Witco Chemicals, E. Gary Cook has played an instrumental role in the 1999 merger of Witco with Crompton Knowles to form CK Witco, a specialty chemicals company.

"Gary's broad experience in specialty and commodity products positions him to provide strong strategic input into building this company," said Suwyn.

L-P's former board member, John Barter, cited his recent appointment to CFO of Kestrel Solutions Inc., a rapidly growing optical network equipment company in California, as the primary reason for his resignation. Barter has served on the company's board since 1998.

"John has been a key contributor to our strategic direction," said Suwyn. "We wish him great success with his new company."

Louisiana-Pacific, now in its 27th year, is a premier supplier of building products, offering a valuable mix of commodity and value-added specialty products to rapidly growing retail, homebuilding and industrial customers. Visit L-P's website at www.LPCorp.com
