ST. LOUIS, MISSOURI, U.S. — Monsanto Co. announced on Dec. 21 that Frank V. AtLee III has resigned from the company's board of directors.

"We thank Frank AtLee for his leadership, insight and many contributions over the years to the board and our company," said Hugh Grant, chairman, president and chief executive officer of Monsanto. "On behalf of the board and all of us at Monsanto, we extend to Frank our sincere gratitude and best wishes."

AtLee served on Monsanto's board for more than 10 years. He served as chairman of the board and chair of the executive committee from June 2000 to October 2003. He was Monsanto's interim president and chief executive officer from December 2002 to May 2003.

"After careful consideration, I feel the time is right for me to step down from Monsanto's board," AtLee said.
