Item 8.01 Other Events

On November 28, 2012, we were notified by the Defense Advanced Research Projects Agency ("DARPA") that we had completed our final milestone, Milestone 10B, under our DARPA Phase III High Productivity Computing Systems ("HPCS") program agreement. The milestone was for $5,500,000, which reflects a decrease in DARPA's financial commitment for Milestone 10B by $1,500,000 due to a mutually agreed-upon modification to one set of commitments under our agreement with DARPA. Based on our level of spending for DARPA HPCS-related work, all of the milestone amount will be credited against our research and development expenses in the fourth quarter of 2012 as part of this co-funding arrangement.

Additional information regarding our agreement with DARPA, as amended, can be found in our reports on Form 8-K filed with the Securities and Exchange Commission on February 16, 2010 and November 1, 2011.
