<font size="2" face="Times New Roman">On June 23, 2006, Simpson Manufacturing Co., Inc. (the &#147;Company&#148;) announced that, effective August 1, 2006, Phillip &#147;Terry&#148; Kingsfather has accepted the position of President and Chief Operating Officer of the Company&#146;s subsidiary, Simpson Strong-Tie Company Inc., to succeed Stephen Lamson. Mr. Lamson has informed the Company that he intends to retire in 2007. Until then, Mr. Lamson intends to continue as Vice President and a Director of the Company. He will work with Mr. Kingsfather in the transition of responsibilities of President and Chief Operating Officer of Simpson Strong-Tie Company Inc.&#160; </font></p>
<p>
<font size="2" face="Times New Roman">Phillip &#147;Terry&#148; Kingsfather, age 59, is currently the Vice President of Simpson Strong-Tie for the Anchor Systems product line and has been with the Company for 27 years. His career with the Company started in 1979 as an outside sales representative in the Pacific Northwest for Simpson Strong-Tie Company Inc., after which, in 1985, he moved on to regional sales manager. He joined the Anchor Systems sales team in 1997 and was instrumental in the roll-out of this product line. Prior to being appointed Vice President in 2004, he had focused on sales to Anchor Systems national accounts.</font></p>
<p>
<font size="2" face="Times New Roman">Mr. Kingsfather will receive a salary of $175,000 per year and a cash profit sharing bonus currently budgeted at $750,000 per year. This bonus amount will be greater or less depending on the Company&#146;s actual performance. In addition, Mr. Kingsfather will receive a housing allowance estimated at up to $130,000 per year for three years. The salary, bonus and housing allowance were approved by the Compensation Committee of the Board of Directors of the Company. The targeted cash profit sharing bonus, if any, will be provided for under the Company&#146;s Officer Cash Profit Sharing Plan. Awards are based on a percentage of the amount by which net profits, as defined by the Committee, for a fiscal quarter exceed a qualifying level of net profits for the Company or such subsidiary, respectively, for that fiscal quarter (as further disclosed in the Company&#146;s Proxy Statement dated March 16, 2006, at page 14, which is incorporated herein by reference). Mr.
Kingsfather&#146;s employment with the Company is at-will.</font></p>
