           Deltek Acquires RFP Proposal and Tracking Automation System

             Industry Leading Software Designed for A/E/C and Other
                       Professional Services Organizations

MCLEAN, VIRGINIA - APRIL 17, 2000 - DELTEK SYSTEMS, INC. (NASDAQ: DLTK). Deltek
today agreed to acquire substantially all assets of A/E Management Services,
including its complete suite of RFP proposal automation and tracking software
for the purchase price of $3.5 million. A/E Management recorded approximately $2
million in revenue for 1999.

         Deltek's President and CEO, Ken deLaski states, "One of the most
important components of end-to-end automation for professional services
organizations is proposal generation and tracking. Over 600 A/E/C (architecture,
engineering, construction), environmental and other professional services firms
use A/E Management's powerful RFP proposal and marketing automation product.
We're very excited to add this product line and employees to the Deltek
organization, and we will continue to offer uninterrupted superior development,
support, consulting, training, marketing, and growth for the RFP software and
its customers."

         "The acquisition brings tremendous synergy and value to the
installed-base of both companies," deLaski continues, "and strengthens Deltek's
market leadership as a provider of professional services automation solutions to
A/E/C firms. It is also a major step forward in achieving Deltek's mission to
deliver comprehensive and functionality-rich applications that automate the
critical business functions across the entire professional services enterprise,
and especially across diverse vertical professional services industries."

         Nancy Watson is the president and owner of A/E Management Services.
"We're very pleased with the agreement announced today. We are confident that
Deltek is the right vendor to acquire our RFP proposal automation and tracking
software and the vendor best able to maintain the high level support that our
customers have come to expect. Deltek and A/E Management have many customers in
common who also consistently rank high on Engineering News Record's annual lists
of top A/E/C firms. By acquiring and combining our organization's institutional
knowledge in marketing and proposal systems with its resources and technology,"
Watson continues, "Deltek is setting the stage for delivering the most
compelling RFP proposal and marketing automation software solutions in the
industry."

         A/E Management's RFP automation solution is designed to help the A/E/C
profession and other professional services organizations win more contracts by
automating the process of collecting, updating, researching and retrieving data
critical to achieving marketing and proposal automation success. Released in
1986, it was the first effective tool that integrated all of an A/E/C firm's
proposal generation and tracking information in one centralized database. The
product's Web interface also helps firms quickly and easily access their
corporate database through an Internet or intranet connection. This empowers
marketing and project teams to produce marketing and proposal documents remotely
and enables firms to make the most of their talent and resources. An RFP product
demonstration may be downloaded online at

         PBS&J is one of the nation's largest engineering-consulting firms with
2,200 employees in 60 offices worldwide. The firm recently went live on A/E
Management's RFP Proposal Automation Enterprise Suite and Web Interface, and is
also one of Deltek's largest users of Advantage, a comprehensive project control
and financial accounting system used by thousands of professional services
organizations throughout the world.

         "We are extremely pleased that Deltek has seized upon this
opportunity," comments PBS&J's CFO Richard Wickett, praising Deltek for its
strategic insight in acquiring A/E Management's RFP product line. "As an
A&E-specific services firm," Wickett observes, "PBS&J is continually looking to
enhance the entire process of automating our enterprise. We believe the
acquisition will create powerful synergies among the products, solutions and
services of both companies. Bringing Deltek's considerable resources and
expertise to bear on automating the RFP process--the lifeblood of virtually all
professional services organizations--will result in an RFP system with rich
functionality beyond any other product currently available."

         Deltek plans to continue supporting the RFP product line's interfaces
with other third party applications, including products provided by Axium, BST
Consultants, Sema-4 and Wind-2.
