NORTH CHELMSFORD, Mass.--Dec. 17, 2002--Courier Corporation, today announced the sale of the assets of its wholly-owned subsidiary, Courier Custom Publishing, Inc. to ProQuest Information and Learning Co. of Ann Arbor, Michigan. Courier Custom Publishing provides customized teaching materials including multi-publisher coursepacks as well as out-of-print book reproductions and books authorized by professors for classroom use. The proceeds of the sale were $1.5 million and will result in an after-tax gain of approximately $0.8 million or $.15 per diluted share in Courier's first quarter which ends on December 28, 2002. The sale is expected to increase the company's previous earnings guidance for fiscal year 2003 by $.15 per diluted share (the amount of the gain) to $3.50 to $3.65 per diluted share and reduce previous guidance on fiscal year 2003 sales to $209 to $215 million.

The knowledge and skills we have developed with Courier Custom Publishing, particularly in the area of e-commerce and electronic direct marketing, are allowing us to greatly enhance Dover's value."
