will always treasure. With the OSC matter now resolved completely in my favour,
I have decided to spend more time with family and pursue my personal interests.
I leave ATI with confidence that under the continued leadership of our CEO David

company in the world."

The Company also announced that David Orton will be nominated for election as
a director of ATI at the Annual Meeting of Shareholders which has been scheduled
for January 26, 2006 in Toronto. Also being nominated are James Fleck, Alan
Horn, John Caldwell, Paul Russo, Ronald Chwang and Robert Young, all of whom
currently are directors of ATI. Mr. Fleck, who is an independent director and
has been serving as the Company’s lead director, has been elected by the Board
as ATI’s new non-executive Chair of the Board.

"ATI will be forever indebted to K.Y. for his founding role with the Company
and his vision and leadership in building this remarkable Company over the past
20 years," stated Mr. Fleck. "The addition of Dave Orton to the Board provides a
logical and welcome succession for K.Y.’s departure." Mr. Fleck also added that,
"K.Y. will be missed by all at ATI but we are comforted that he will continue to
be available to provide his counsel to us as the need arises."
