 SANTA BARBARA , CA —July 26, 2007—Green Hills Software,
        Inc., the technology leader in device software optimization (DSO) and real-time
        operating systems (RTOS), today announced that the Green Hills product
        suite supports Cavium Networks’ (NASDAQ:CAVM) OCTEON™ Multi-core
        MIPS64® processor family. This support includes the MULTI integrated
        development environment, TimeMachine tool
        suite, Green Hills compilers,
        DoubleCheck static analysis tools, µ-velOSity royalty-free
        real-time operating system and Green Hills
        Probe which are now available for the OCTEON family of multi-core
        MIPS64 processors. The Green Hills products enable network equipment
        providers to reduce their cost of software development and significantly
        shorten the time-to-market for their networking, security, control plane,
        wireless, storage and broadband gateway applications, based on the market
        leading OCTEON processors. “Green Hills Software is a welcome addition to the Cavium Networks
        ecosystem,” said Rajiv Khemani, vice president of marketing and
        sales at Cavium Networks. “Their software solutions for multicore
        processor development are being used by our common customers in the wireless
        infrastructure market. This portfolio of tools and operating systems
        optimized for the OCTEON processors allows rapid deployment of leading
        performance networking products,” he said. Green Hills’ products for the OCTEON processor family come from
        25 years of experience providing development tools and RTOSes that make
