Tecnomatix to Acquire USDATA Corporation, Strengthening Reach Across All Areas of Manufacturing

HERZLIA, Israel and RICHARDSON, Texas--July 30, 2003--

Tecnomatix Underscores Position as Manufacturing Process Management (MPM) Leader by Incorporating Widely Used Factory Floor and Execution Systems Software

Tecnomatix Technologies Ltd. , the driving force in Manufacturing Process Management (MPM), today announced that it has agreed to acquire substantially all the assets of USDATA Corporation (www.usdata.com), a leading developer of supervisory-level control (SCADA) and manufacturing execution systems (MES). The acquisition is in line with Tecnomatix' vision for a complete MPM solution spanning the entire manufacturing process lifecycle.

Tecnomatix intends to integrate USDATA's SCADA product FactoryLink(R) and its MES product Xfactory(R) with the Tecnomatix eMPower(TM) offering to create an environment for collaborative planning engineering and execution of manufacturing processes. This will accelerate new product introductions and provide a critical feedback loop from the factory floor to engineering, allowing manufacturers to compare shop-floor performance with original design and process plans, and to implement manufacturing improvements on an ongoing basis.

"The acquisition of USDATA is a major step forward in our strategy to broaden the footprint of MPM into other high-potential areas of manufacturing," said Harel Beit-On, chairman and chief executive officer of Tecnomatix Technologies. "This will enable Tecnomatix to expand our presence in the manufacturing execution systems domain and to address important industries where we do not operate today. Our expanded MPM solution will give manufacturers more visibility and control over processes on the factory floor, so that they can respond quickly to market demand and deliver to their customers the products they want, when they want them and at affordable costs."

"USDATA customers and partners will benefit tremendously from this transaction," said James E. Fleet, interim CEO and president of USDATA Corporation. "The strong commitment that Tecnomatix is making to the USDATA product set and customer base will insure that continuous innovation is delivered to the market. FactoryLink(R) will continue to be available on a standalone basis, sold through the USDATA network of highly experienced resellers and integrators."

"We expect the integration of FactoryLink(R) and Xfactory(R) to go smoothly because of the similar open architectures our two companies have chosen to manage manufacturing data," Beit-On continued. "eMPower is built on the concept of the electronic bills of processes (eBOP), which manages product operations and resources. USDATA's model-based technology will facilitate the extension of our eBOP into the execution domain to include routes, work-in-process (WIP) and orders. This enhanced eBOP will be the basis of a new class of integrated execution applications, providing customers rich functionality and integration to their business process. We are excited, not only about the USDATA technology, but also the quality and expertise of their employees, distributors and system integrators. I am confident they will make a significant contribution to the success and growth of Tecnomatix."

Tecnomatix announced the agreement in consideration for the issuance of up to 1,011,747 Tecnomatix shares, subject to certain adjustments. Based on the closing price of $10.16 per Tecnomatix share as of July 29, 2003, the shares to be issued as consideration for the acquisition are valued at approximately $10.3 million. As part of the asset purchase transaction, SCP Private Equity Partners II, L.P., the primary stockholder of USDATA, will purchase from Tecnomatix 113,838 of its shares at $15.65 per share.
