Calix to Acquire Occam Networks

Calix, Inc. (NYSE: CALX) and Occam Networks, Inc. (NASDAQ: OCNW) today announced that the companies have entered into a definitive agreement for Calix to acquire Occam Networks in a stock and cash transaction valued at approximately $171 million, which is approximately $7.75 per outstanding share of Occam Networks stock.

Upon the completion of the acquisition, each outstanding share of Occam Networks common stock (other than those shares with respect to which appraisal rights are available, properly exercised and not withdrawn) will be converted into the right to receive (a) $3.8337 per share in cash, without interest plus (b) 0.2925 of a validly issued, fully paid and non-assessable share of Calix common stock. After the completion of the acquisition, former Occam Networks stockholders will own between 16.5 percent and 18.9 percent of the outstanding shares of Calix’s common stock based on the number of Calix shares outstanding as of September 15, 2010.

Additionally, after the completion of the acquisition, one non-management member of the current Occam Networks Board of Directors is expected to be appointed to serve on the Calix Board of Directors.

The combined organization of Calix and Occam Networks is expected to provide communications service providers across North America, the Caribbean, Latin America, and select global markets with an enhanced portfolio of advanced broadband access systems, and accelerate innovation across the expanded Calix Unified Access portfolio. The acquisition is expected to result in more access options over both fiber and copper for communications service providers to deploy, which could expedite the proliferation of advanced broadband services to both residential and business subscribers, including such services as high-speed Internet, IPTV, VOIP, Ethernet business services, and other advanced broadband applications.

“The rate of change is accelerating for communications service providers, and Calix is fully committed to providing our customers with the broadest portfolio of innovative access network options to adapt to this changing world,” said Carl Russo, president and chief executive officer of Calix. “By combining Occam Networks’ expertise in IP and Ethernet, Calix’s strength in fiber access, and both companies’ experience in copper access, we believe there is a clear opportunity to further enhance the Calix Unified Access portfolio, accelerate its future innovation, and enable greater broadband deployment by communications service providers globally. As a result of this acquisition, communications service providers can expect new innovations to the expanded Calix Unified Access portfolio that directly address the emerging needs of the broadband-connected consumer while also making these communications service providers more capitally and operationally efficient. We are excited about what this combination of top engineering and support talent will mean to bringing new and accelerated access network innovation to our joint customers and communications service providers.”

“With more than 380 communications service providers as customers and a robust access systems portfolio, Occam Networks has become synonymous with IP and Ethernet access innovation, yet with the rate of change in our industry continuing to increase, we were looking for ways to accelerate our rate of innovation,” said Bob Howard-Anderson, Occam Networks’ president and chief executive officer. “By combining our extensive IP and Ethernet access platforms and resources with Calix’s robust Unified Access portfolio and deep expertise in fiber access, we lay a foundation for extensive future innovation. We are excited about the opportunity to combine forces with Calix, and with the cultures of continued innovation and commitment to customer success that both companies share, we believe we can bring accelerated access network innovation and opportunity to communications service providers, consumers, and businesses alike.”

Calix expects to complete the acquisition in the fourth quarter of 2010 or first quarter of 2011, subject to Occam Networks stockholder approval, receipt of required regulatory clearance and the satisfaction of certain other customary closing conditions. Occam Networks stockholders representing approximately 27 percent of Occam Networks’ outstanding common stock have signed an agreement to vote their shares in favor of this transaction. It is anticipated that the acquisition will be accretive to Calix’s non-GAAP earnings per share in the second quarter of 2011.
