Item 2.01     Completion of Acquisition or Disposition of Assets

        On April 29, 2005, TriQuint Semiconductor, Inc. (“TriQuint”) completed the sale of its optoelectronic operations in Breinigsville, Pennsylvania, and Matamoros, Mexico, to CyOptics, Inc. (“CyOptics”) of Lehigh Valley, Pennsylvania. The sale was an asset sale including the products, manufacturing equipment, inventory, the Mexican entity, related intellectual property rights and other assets that constitute the operation that manufactures indium phosphide (“InP”) optical chips and components for the optical networking market. CyOptics plans to employ the vast majority of TriQuint’s approximately 100 employees in Pennsylvania and approximately 150 employees in Mexico. The terms of the sale were $13.5 million cash at closing, a promissory note for approximately $5.5 million (subject to adjustment based on the value of certain working capital accounts) and preferred stock representing approximately 10% of the voting shares of CyOptics. CyOptics also assumed certain liabilities associated with the optoelectronics operations. In connection with the sale, the Company is expected to incur approximately $0.5 million of facility clean-up and other costs, approximately $0.6 million of commissions and legal fees and approximately $0.6 million of severance and employee retention costs in the second quarter of 2005.

Separately, on March 7, 2005, TriQuint Optoelectronics, a wholly-owned subsidiary of TriQuint (“TriQuint Optoelectronics”), entered into a purchase and sale agreement (the “Agreement”) to sell to Anthem Partners, LLC the land and building and related facilities occupied by TriQuint Optoelectronics’ operations in Breinigsville, Pennsylvania (the “Facility Sale”). Pursuant to the Agreement, TriQuint Optoelectronics and Anthem have agreed to negotiate in good faith a lease for approximately 90,000 square feet of the 849,000 square foot facility for the optoelectronics operations. The lease term will be two years from the closing of the Facility Sale, with an option to renew. TriQuint Optoelectronics intends to assign the lease to CyOptics at the time of closing of the Facility Sale, with TriQuint Optoelectronics guaranteeing the base rent due under the initial two year term. The sale of the facility in Breinigsville, Pennsylvania to Anthem Partners LLC has not been completed. In the intervening period, TriQuint Optoelectronics will lease facility space in Breinigsville, Pennsylvania to CyOptics for its operations.
