NYSE To Suspend Trading in ProQuest Co., Moves to Remove from the List
NEW YORK, March 21, 2007 -- NYSE Regulation, Inc. (“NYSE Regulation”) announced today that it determined that the common stock of ProQuest Co. (the "Company") – ticker symbol PQE – should be suspended prior to the opening on Wednesday, March 28, 2007, or such earlier date as the Company commences trading in another securities marketplace or if there is material adverse development. The Company expects its common stock to be quoted on the Pink Sheets following suspension.

The decision was reached in view of the fact that the Company is a late filer. Also, the Company was under review by NYSE Regulation in light of the delay in filing with the Securities and Exchange Commission its December 31, 2005 Form 10-K and certain of its 2006 Form 10-Q filings.

On March 21, 2007 , the Company announced that it anticipates it will not be able to complete the filing of its December 31, 2005 Form 10-K by April 2, 2007 . This date is beyond the maximum 12-month period otherwise available to complete the filing as permitted under the NYSE’s rules.

The Company has a right to a review of this determination by a Committee of the Board of Directors of NYSE Regulation. Application to the Securities and Exchange Commission to delist the issue is pending the completion of applicable procedures, including any appeal by the Company of NYSE Regulation staff’s decision. The NYSE noted that it may, at any time, suspend a security if it believes that continued dealings in the security on the NYSE are not advisable.
