Clarus Selected by Parsons Brinckerhoff to Deliver Web-Based Purchasing Nationwide.

ATLANTA--(BUSINESS WIRE)--July 20, 1999--

Parsons Brinckerhoff, one of the nation's largest

engineering firms, will use the Clarus E-Procurement

solution to take advantage of national purchasing alliances

Clarus Corporation (Nasdaq:CLRS), a leading provider of Web-based commerce applications, today announced that Parsons Brinckerhoff, one of the largest engineering companies in the U.S., has selected the Clarus(TM) E-Procurement solution to be deployed throughout its 250 nationwide offices.

The engineering company expects Clarus' Web-based procurement solution will streamline purchases of non-production goods and services through pre-approved supplier channels.

Parsons Brinckerhoff, a company that has worked on infrastructure projects ranging from the original New York City IRT subway to Atlanta's MARTA mass transit system, expects an initial 500 employees will use the Clarus E-Procurement system within three months. By mid-2000, the company will complete electronic procurement deployment to more than 4,000 employees.

Michael Fisher, senior vice president and director of administration at Parsons Brinckerhoff, explains, "In our evaluation of Clarus E-Procurement, we determined that the system will pay for itself and will help our organization address global cost and compliance issues. Instead of buying locally from a variety of vendors, all with low volume purchasing levels, our employees will tap into a consolidated network of suppliers to successfully leverage negotiated contracts."

Parsons Brinckerhoff chose Clarus E-Procurement, the cornerstone Clarus(TM) Commerce application, over competitive offerings from enterprise resource planning companies because it perceived that Clarus offered the most advanced integration capabilities, the best customer service and the most comprehensive catalog management system available in the Web purchasing market today.

The strong synergy between Clarus and Microsoft also influenced Parsons Brinckerhoff's decision. Clarus Commerce is powered by Microsoft(R) Windows NT(R) Server, its built-in Web Server, as well as Microsoft SQL Server(TM). The enterprise integration framework for Clarus Commerce, Clarus(TM) Fusion, enables integration between heterogeneous backoffice systems and publishes Extensive Markup Language (XML) documents adhering to BizTalk standards. The Clarus solution also takes advantage of Microsoft Site Server 3.0 Commerce Edition (SSCE) and provides secure purchase and order payment communications to suppliers via the Commerce Interchange Pipeline (CIP).

Stephanie Parson, vice president and chief information officer of Parsons Brinckerhoff, explains, "As an Oracle ERP shop, we selected Clarus to seamlessly integrate to our backoffice environment and leverage advanced Microsoft technologies. We expect the flexibility and scalability of the Clarus system will help us effectively deliver online procurement to our broad base of global employees."

"Clarus partners with high-growth organizations such as Parsons Brinckerhoff to evaluate their business needs and forecast how Internet procurement systems can help achieve ROI through across-the-board cost savings," said Steve Jeffery, CEO and president of Clarus. "For Parsons Brinckerhoff, Clarus E-Procurement will also help to slash purchase order processing costs and redirect personnel to work on strategic initiatives instead of clerical duties."
