KB HOME ENTERS INTO AN EXCLUSIVITY PERIOD REGARDING THE SALE OF ITS
FRENCH OPERATIONS

Los Angeles, CA, May 17, 2007— KB Home (NYSE: KBH) announced today that it has entered into an exclusivity period based on a final, irrevocable, binding and fully financed offer by PAI Partners (“PAI”) to acquire its entire 49% ownership interest in its French subsidiary Kaufman & Broad SA representing 10,921,954 shares at a price of 55.00 euros per share. Total cash proceeds from the sale, at current exchange rates, would exceed $800 million. PAI’s all cash offer is binding but remains subject to customary terms and conditions including regulatory approval. The transaction could close in the third quarter of 2007.

“After a thorough review of various strategic alternatives with respect to its French operations, which included conducting a competitive bidding process launched earlier this year, KB Home and its board of directors believe the proposed transaction would be in the best interest of its shareholders. The sale would further KB Home’s focus on its core homebuilding operations in the U.S. where long-term prospects are excellent,” said Jeffrey Mezger, KB Home’s president and chief executive officer.
