Mimix Broadband, Inc. Sells Its Gallium Arsenide (GaAs) Foundry to Universal Semiconductor Technology, Inc.

Mimix 100% Fabless with Access to Unique GaAs Processes

April 4, 2006, Houston, Texas - Mimix Broadband, Inc., a supplier of microwave and millimeter-wave Gallium Arsenide (GaAs) semiconductors, announced today that it has executed a definitive agreement to sell its Gallium Arsenide (GaAs) foundry to Universal Semiconductor Technology, Inc. (USTI), a high technology investment company. As part of this agreement, Mimix and USTI have also entered into a multi-year GaAs wafer supply and non-compete agreement, guaranteeing Mimix customers of continuous supply.

In June 2005 Mimix completed the purchase of substantially all of the assets of Celeritek Inc., including the Santa Clara, California, GaAs foundry that Mimix has sold to USTI. USTI will provide Mimix with foundry services for multiple processes including active GaAs MESFET, pHEMT and HBT, as well as thin film silicon and ceramic circuit components and substrates.

"This agreement is ideal, since it allows Mimix to be 100% fabless, while continuing to provide our customers with a continuous supply of the unique device intellectual property developed at Celeritek and now owned by Mimix," stated Rick Montgomery, CEO, Mimix Broadband, Inc. "Our customers benefit greatly from this deal. No foundry disruption will occur in manufacturing our semiconductor products, and they can expect the same quality and reliability from the products."

"We are enthusiastic about this agreement," stated Mr. Bao Hua Zheng, Chairman of Universal Semiconductor Technology, Inc. "USTI will have the opportunity to manufacture GaAs semiconductors, using proven and industry-leading processes, and the foundry will serve as a platform to develop new, cutting-edge processes to serve customers targeting the compound semiconductor industry."

Montgomery added, "We are extremely pleased to have executed an agreement with USTI, because its financial resources, experience and expertise position them to be a successful partner and supplier for the long term."
