Boise Cascade Corp., a wood and paper products maker, has agreed to acquire OfficeMax Inc. for nearly $1.2 billion in cash and stock in a deal that would more than double the size of its office products distribution business.

OfficeMax is the third biggest U.S. office products retailer, behind Office Depot and Staples.

"Clearly, this gains us scale in office solutions," Boise chairman and chief executive officer George Harad said Monday. "It's an excellent fit between complementary businesses."
