Lockheed Martin Unit Selects PTC® Product Development System

PTC Product Development System Replaces Legacy Data Management Systems

Needham, MA – February 19, 2008 – PTC (Nasdaq: PMTC), The Product Development Company®, today announced that Lockheed Martin’s Electronic Systems (ES) has selected Windchill®, PTC’s Product Lifecycle Management solution, to replace its multiple legacy Product Data Management systems. Windchill will allow Electronic Systems to move toward a consolidated Technology platform for managing all critical product information. Electronic Systems is one of Lockheed Martin’s four business areas.

Lockheed Martin Electronic Systems will use Windchill to support change and configuration management in the production of key military systems and to smooth the IT consolidation among its multiple lines of business. Additionally, Windchill will enable Electronic Systems to share design details early in the design process to better inform its decision makers and to provide visibility and traceability during the entire development effort.

In addition to Windchill, Lockheed uses other products within the PTC Product Development System (PDS), including Pro/ENGINEER® for digital product designs, Mathcad® for engineering calculations and Arbortext® for dynamic publishing.

“We are pleased to provide Lockheed Martin Electronic Systems with a single Technology platform," said C. Richard Harrison, president and chief executive officer, PTC. “Lockheed Martin has long recognized the value of optimizing business-critical product development processes like a well-defined and orderly process for controlling changes to product configurations. We look forward to helping them realize the value that the PTC Product Development System can bring to their PLM deployment.”
