Quest to Determine True Financial Statements; ProQuest Restates, Shareholders Launch Class Action Suit -- Lawyers at KGS Announce Filing

Market Wire, February, 2006

Kahn Gauthier Swick, LLC ("KGS") announces that a securities class action lawsuit has been commenced in the U.S. District Court for the Eastern District of Michigan, on behalf of shareholders who purchased, exchanged or otherwise acquired the common stock of ProQuest Company (NYSE: PQE) between January 9, 2003 and February 8, 2006. No class has yet been certified in this action.

UNTIL A CLASS IS CERTIFIED, YOU ARE NOT REPRESENTED BY COUNSEL UNLESS YOU RETAIN AN ATTORNEY.

The Complaint that has been filed alleges that defendants have violated federal securities laws by issuing a series of materially false statements regarding ProQuest's business and financial results. According to these allegations, ProQuest announced on February 9, 2006 that it had materially understated its deferred income and accrued royalty accounts, and had materially overstated its prepaid royalty account.

Consequently, investors suffered large losses after the true facts concerning the Company emerged on or about February 9, 2006, when ProQuest's stock collapsed to a low of $21.90 per share, before closing at $24.19 on volume of 3 million shares -- 13 times the average.
