Box 9777 Federal Way WA 98063-9777 Tel (253) 924-2345 July 26, 2001 To our friends in Oregon: For nearly 100 years, Weyerhaeuser has played an important role in the growth of Oregon and the many communities in which we operate. Recently, we proposed to further strengthen our role by combining Weyerhaeuser and Willamette to create a global leader in our industry. On June 7, Willamette shareholders endorsed our proposal by electing three Weyerhaeuser-supported nominees to Willamette's board of directors. Since we announced our proposal, Weyerhaeuser has met with many Oregonians to outline why we believe a combination of these two companies would be in the best interests of employees, communities and customers. We would like to thank you for the opportunity to meet with you and for the support you have provided throughout this process. We also would like to thank the employees of both companies. We know these past months have been challenging. But through your dedication, hard work and focus, Weyerhaeuser and Willamette employees have continued to safely meet the needs of customers. That's why we continue to believe that Weyerhaeuser and Willamette employees truly are among the best in our industry. Weyerhaeuser is proud of its history in Oregon and we look forward to a long future here. We believe that a combination of our two companies will ensure that Oregon retains its leadership position in our industry. At Weyerhaeuser, the future is growing and we want Oregon to play an even larger role in that growth. Sincerely, /s/ Steve Steven R.
