News Release

For Immediate Release: 10 December 2001

Fairfax, Va. (December 10, 2001) - PEC Solutions, Inc. (NASDAQ NM: PECS), announced today that the company has been awarded a $1 million task order under an existing contract from the Fairfax County Circuit Courts Office to develop software upgrades and technology enhancements to the Courts Automated Recording System (CARS). PEC has been engaged with the county to develop and support the CARS initiative since the late nineties.

CARS is a land records and public services document capture system that automates the filing of deeds, trusts, certificates of satisfaction, financial statements, marriage licenses, wills, notaries, judgments, and other documents. The automated system has the capability to process thousands of documents a day. CARS provides a web-based retrieval component which enables stake-holders to securely access a constantly growing database of official court records.

Under this new tasking, PEC will adapt the current CARS implementation to evolving court procedures and ready the system for eGovernment implementation, ultimately serving the citizens of Fairfax better through reducing processing errors and increasing end-user effectiveness and efficiency.
