Teradyne Signs Molex Incorporated as Second-Source Producer of GbXT High-Speed, High-Density Connector

Identical design ensures true intermateability and interchangeability

Nashua, NH - January 20, 2003 - Teradyne, Inc. (NYSE: TER) Connection Systems Division (TCS), a leading provider of high performance interconnect and electronic manufacturing services, and Molex Incorporated, today announced they have signed a second-source licensing agreement which grants Molex the right to manufacture, market and sell the GbX connector.

Under terms of the agreement, Molex is licensed under Teradyne's patents, trademarks, and technology to manufacture and sell the GbX product family worldwide. The two companies will work jointly to deliver truly intermateable, interchangeable products by sharing design and manufacturing processes. Molex expects to begin production of the four pair configuration of the GbX connector in September 2003.

"The Teradyne-Molex partnership is unique in that the two companies deliver products that share design, not just specification," said Rick Schneider, president Teradyne Connection Systems. "We collaborate continuously over the product lifecycle to improve our respective production and process capabilities. OEM users can source either company's components with confidence that the parts will work together and meet their performance and reliability requirements."

The GbX license agreement marks the fourth product generation that Teradyne has licensed to Molex since 1995, beginning with Teradyne's HDM® connector family and extending to include its industry-leading VHDM® and VHDM-HSDT high-speed, high-density connector platforms.

Martin Slark, president and chief operating officer, Molex, Incorporated, added, "We are very pleased about extending our second-source partnership with Teradyne. The GbX connector is well positioned in the marketplace, enabling real-world system solutions with exceptional mechanical integrity and electrical performance. Molex will work aggressively to tool the GbX product family."

Teradyne's GbX connector provides the highest level of density available today, offering an upgrade path beyond existing 2mm platforms. The GbX 4-pair platform offers 55 differential pairs per linear inch, allowing for the most XAUI links in the industry today. GbX is currently available from Teradyne in 4-pair and 5-pair versions (69 differential pairs per inch) with a complete breadth of components including power, guidance and polarizing.
