OCCAM NETWORKS, INC. ANNOUNCES INTENTION TO

ADJOURN SPECIAL MEETING OF STOCKHOLDERS

Special Meeting to be Reconvened on February 22, 2011

SANTA BARBARA, January 26, 2011 — Occam Networks, Inc. (Nasdaq:OCNW) announced today that it intends to convene and immediately adjourn the special meeting of its stockholders, which is scheduled for January 27, 2011 for the purpose of obtaining the approval of Occam stockholders of the proposed acquisition of Occam Networks by Calix, Inc. pursuant to the Agreement and Plan of Merger and Reorganization dated September 16, 2010, without a vote on the merger proposal.  The special meeting will be adjourned until 10:00 am (local time) on February 22, 2011, at Occam’s offices at 3185 Laurelview Court, Fremont, California, 94538, in response to an order from the Delaware Court of Chancery requiring Occam Networks to make available to its stockholders prior to the vote additional information and requiring a deposition of Occam’s financial advisor.

Occam Networks will file with the Securities and Exchange Commission additional soliciting materials (the “Additional Soliciting Materials”) that supplement the definitive proxy statement/prospectus dated December 14, 2010 (the “Proxy Statement”) by providing additional disclosure as directed by the Delaware Court of Chancery.  Occam Networks stockholders are urged to carefully read the Additional Soliciting Materials when available.

As of the close of business on January 25, 2011, a preliminary count indicated that the holders of approximately 63% of Occam’s outstanding shares intended to vote in favor of the merger.  The results of voting at the adjourned special meeting, once reconvened on February 22, 2011, could differ materially from this preliminary count.

As will be described in the Additional Soliciting Materials, any stockholder who has previously delivered a proxy may revoke it at any time before the polls close at the adjourned special meeting. Stockholders who do not wish to rescind their votes, including stockholders who have already voted in favor of the merger proposal or the adjournment proposal and do not wish to change that vote, do not need to take any further action. All shares of Occam Networks common stock represented by properly executed proxies that are received in time for the special meeting, as adjourned, and that are not revoked, will be voted at the adjourned special meeting in the manner specified by the holder.

Occam Networks’ stockholders of record as of December 13, 2010, the record date for the special meeting, who have not yet voted and still wish to do so may vote in the manner set forth in the Proxy Statement.

Occam Networks’ board of directors reaffirms its recommendation that Occam Networks’ stockholders adopt the merger agreement and encourages stockholders to vote “FOR” the adoption of the merger agreement at the adjourned special meeting.

Stockholders who have questions about the merger or how to submit proxies, or who need additional copies of the Proxy Statement or the enclosed proxy card or about the Additional Soliciting Materials may contact Occam Networks’ proxy solicitor, Innisfree M&A Incorporated, at 1-888-750-5834.
