Delphi Electronics and Mathsoft to quantify benefits of calculation management at National Manufacturing Week

Business Wire, March 6, 2006

Mathsoft Engineering & Education, Inc.:

WHO:     Brian Johnson, Engineering Group Manager, Delphi Delco
         Electronics Systems, and
         Allen Razdow, CTO, Mathsoft(R) Education & Engineering, Inc.

WHAT:    "Why Calculations Count: A Delphi Electronics & Safety
         Case Study"

         Johnson will detail how sound calculation management using
         Mathcad(R) calculation software helps Delphi Delco
         Electronics meet the growing challenge of designing
         complex products with fewer engineers. Razdow will outline
         the principles underlying calculation management at Delphi
         and engineering organizations around the world.

WHEN:    Tuesday, March 21, 2006, 3 to 3:50 p.m. CST

WHERE:   National Manufacturing Week, the leading education conference
         and exhibition for the U.S. manufacturing community. Room 32,
         Donald E. Stephens Convention Center,
         Rosemont (Chicago), Ill.

DETAILS: Delphi Delco Electronics has used Mathcad to develop standard
         analysis templates and foster extensive reuse of existing
         designs to save engineering time, improve efficiency,
         increase accuracy, comply with standards, ensure global
         consistency and satisfy new customers. Razdow will explain
         how mismanaging calculations can result in needless redesign
         and disastrous errors, and the squandering of precious
         intellectual capital.

Mathsoft's Mathcad calculation software is the choice of more than 1.8 million engineers in more than 50 countries, including users at BAE Systems, Boeing, DuPont, Honeywell, Lockheed Martin, Rolls Royce and Universal Studios.
