Leading Government Contractor Chooses Selectica Contract Lifecycle Management Solution

SAN JOSE, CA--(Marketwire - April 2, 2008) - Selectica, Inc. (NASDAQ: SLTC), a leading provider of enterprise contract lifecycle management (CLM) solutions, today announced that ManTech International Corporation (NASDAQ: MANT) plans to implement Selectica Contract Performance Management. ManTech International Corporation, a leading provider of innovative technologies and solutions for mission-critical national security programs, was founded in 1968 and since then it has grown to become one the most successful professional services companies supporting the Intelligence Community -- including the departments of Defense, State, Homeland Security, Justice -- as well as the Space Community and other federal agencies. ManTech has also been recognized nationally as a leading technology company. In 2007, BusinessWeek.com rated ManTech one of the 75 Fastest Growing Technology Companies and Business 2.0 magazine chose ManTech as one of its Top 100 Fastest Growing Technology Companies for the second year in a row.

"As we continue to expand our involvement with mission critical government programs, it has become essential to streamline the way we author, access, audit, manage, and retain the contracts we sign with a wide variety of government entities," said Mike Uster, Vice President of Contracts and Procurement at ManTech. "Automating these processes with a highly configurable contract management solution that features an indexable electronic repository will improve our business efficiency and help minimize overhead costs."

ManTech's selection process included preparation of a detailed requirements document specifying 107 requirements in 11 functional areas and solution demonstrations that addressed contract management scenarios. At the conclusion of this process, ManTech chose Selectica Contract Performance Management. "We selected Selectica because of its usability, configurability, and robust feature set," Uster said.

"With their choice of Selectica, ManTech has demonstrated a commitment to our product, our professional services, and our employees," said Doug Bell, Selectica's Vice President of Marketing, Contract Management Solutions. "The success of our CLM solution is based on similar commitments from a growing number of companies in healthcare, telecommunications, manufacturing, and, of course, government contracting, and we will strive to live up to, and exceed, the expectations of this expanding customer base."
