Item 1.01. Entry Into a Material Agreement.

On January 24, 2007, Registrant entered into an agreement with SPEL Semiconductor Limited (“SPEL”), which currently provides Registrant with TDFN packaging and testing services for semiconductor devices, for SPEL to expand these services to include UDFN and uUDFN packages. As part of the agreement, Registrant will purchase and consign to SPEL approximately $2.2 million of packaging and test equipment in exchange for future discounted pricing on TDFN, UDFN, and uUDFN packaging services provided by SPEL to Registrant using such equipment.
