On October 6, 2010, Mr. Steinhardt, Mr. Chen, Mr. Sheeler, SOM and Ilex, on behalf of themselves, individually, and all other similarly situated stockholders of the Issuer (collectively, the "Plaintiffs") filed a complaint in the Delaware Chancery Court against Robert Howard-Anderson, Steven Krausz, Robert About, Robert Bylin, Thomas Pardun, Brian Strom and Albert Moyer (collectively, the "Defendants") alleging, among other things, that the proposed acquisition of the Issuer by Calix, Inc. (the "Acquisition") violates the fiduciary duties owed by the Defendants to the Plaintiffs.  In particular, the complaint alleges that (i) the Acquisition is unfair to the Issuer's public stockholders and represents an effort by the Defendants to aggrandize their own financial position and interests at the expense of the Plaintiffs and (ii) t he Defendants have breached their fiduciary duties to the Issuer's stockholders by failing to engage in an honest and fair process that maximizes stockholder value.

From time to time the Reporting Persons and their representatives and advisors may communicate with other stockholders, industry participants, advisors and other interested parties concerning the complaint and the matters referenced therein and raised thereby.  Other interested stockholders and parties may choose to be added to the complaint and may act in concert with the Reporting Persons and other stockholders as to any such matters.
