ATS Corporation Awarded the Yonkers Justice Information System Project

MCLEAN, VA--(Marketwire - May 29, 2007) - ATS Corporation ("ATSC") (OTCBB: ATCT) today announced that the Company has been awarded the Yonkers Justice Information System project ("YJIS"), valued at approximately $3.9 million, by the Yonkers, New York Police Department.

Effective immediately, ATSC will begin implementing an extensive, state of the art Law Enforcement Records Management System with a tightly integrated Mobile Field Reporting System in concert with an advanced XML message broker that interfaces with legacy Yonkers infrastructure. The Yonkers police department employs 758 sworn officers and civilian personnel that will utilize the ATS YJIS solution, promoting data access and sharing for numerous agencies, including, but not limited to Yonkers Police Department, Court System, Municipal Agencies, Fire Department, Department of Works, and Department of City Planning. For this project, ATS has partnered with Denali Solutions for the Records Management System and with Patron Systems for the Mobile Field Reporting.

"Over the past several years, E-Government initiatives have rapidly increased nationwide," said Martin Gillespie, ATSC's Vice President and General Manager of Public Safety Solutions. "Our proven, best of breed solutions will help the Yonkers Police Department facilitate interoperability and information sharing across Local, County, State, and Federal Law Enforcement and Court systems. We look forward to positive results from our efforts in Yonkers."

Implementation for this project is estimated to take 14 months with annual maintenance and support continuing beyond the implementation dates for up to ten years.
