Lennox International to Sell Interest in Heat Transfer Joint Venture to Outokumpu

April 5, 2005

DALLAS, April 5, 2005 /PRNewswire-FirstCall via COMTEX/ -- Lennox International Inc. (NYSE: LII) announced today that Outokumpu Copper Products OY of Finland has exercised its option to purchase LII's 45 percent interest in their heat transfer joint venture for approximately $39 million. The transaction is conditioned on the sale of Outokumpu Copper Products OY to Nordic Capital, announced publicly today by Outokumpu. The financial impact of this transaction is not expected to significantly impact LII's 2005 financial performance, excluding an anticipated gain on the sale, which will be quantified when the transaction is completed.

The boards of directors of both companies have approved the transaction, which is expected to close late in the second quarter of 2005. Nearly three years ago LII and Outokumpu announced a joint venture, with Outokumpu initially purchasing a 55 percent interest in LII's heat transfer business segment for $55 million.

"Outokumpu's purchase of LII's remaining interest in the heat transfer business joint venture allows us to further focus our energy and resources on our three core businesses: Heating & Cooling, Refrigeration, and Service Experts," said Bob Schjerven, LII chief executive officer.

Operating in over 100 countries, Lennox International Inc. is a global leader in the heating, ventilation, air conditioning, and refrigeration markets.
