PROQUEST ANNOUNCES EARNINGS CALL AND NAME CHANGE

Expects to File 2005 Restated Consolidated Financial Statements in 45 to 60 Days

Ann Arbor, Michigan, June 29, 2007 - ProQuest Company (OTC: PQES.PK, "the Company"), a publisher of education materials and provider of education solutions in the K-12 market, will hold a conference call to discuss first half 2007 results on Thursday, July 26, 2007 at 3:00 p.m. Eastern Time. The call will be based on preliminary unaudited results through June 30, 2007 for its Voyager Expanded Learning, Learning A-Z and ExploreLearning businesses.

The Company also reported today that it will change its name to Voyager Learning Company effective Saturday, June 30, 2007. The name change is being made pursuant to the terms of the sale of ProQuest Information and Learning to Cambridge Information Group (CIG) in February 2007 under which CIG acquired the rights to the ProQuest name. Effective Monday, July 2, 2007, the Company's corporate website address will change to www.voyagercompany.com.

Also effective with the opening of business on Monday, July 2, 2007 the Company's ticker symbol will change from PQES to VLCY, with no interruption of trading in the Company's shares. The new name and ticker symbol will have no effect on the number of shares owned by current shareholders. The name change will be automatic and shareholders will own the same number of shares of Voyager Learning Company as they own of ProQuest Company.

The Company also announced that it now expects to file its 2005 10-K, including its restated consolidated financial statements, in the next 45 to 60 days. Previously the Company announced in its March 21, 2007 press release that it anticipated filing its 2005 10-K in the second quarter of 2007. While the Company and its independent auditor, KPMG LLP ("KPMG"), have made significant progress, finalizing open issues has been more difficult than expected. There can be no assurance that additional issues will not be identified which could further delay the filing of the 2005 10-K.

To listen to the Company's upcoming conference call, please dial (888) 688-0384 at 3:00 p.m. Eastern Time on Thursday, July 26, 2007. The call will be recorded and archived until Thursday, August 2, 2007 and can be replayed by calling (800) 642-1687, and entering ID#6064132. The conference call will also be webcast and archived at the Company's website (which effective Monday, July 2, 2007 will be www.voyagercompany.com).
