is buttressing its resistance to

Weyerhaeuser's

hostile takeover bid.

The forestry products company said Thursday it sent a letter to the Tacoma, Wash.-based Weyerhaeuser that reiterated Willamette's rejection of its rival's "low-ball offer." Willamette, which is based in Portland, Ore., also sent a letter to its shareholders, urging them to reject Weyerhaeuser's "inadequate" takeover bid.

Weyerhaeuser launched a $5.4 billion, or $48-per-share, bid for Willamette last November, which Willamette rejected. But Weyerhaeuser has

been steadfast in the face of Willamette's equally firm stance.
