On November 10, 2008, we entered into an amendment to our agreement covering Phase III of the Defense Advanced Research Projects Agency's ("DARPA") High Productivity Computing Systems program. This amendment incorporates Intel technologies into our development project and establishes later delivery dates, new milestones and new payment dates and amounts.

The overall goal of the DARPA program, which has not changed, is to facilitate the development of the next generation of high productivity computing systems for the national security, research and industrial user communities, with significant improvements in performance, programmability, portability and robustness. Under our agreement, we are to develop a prototype system that demonstrates the functionality required for scaling to multiple sustained petaflops (1,000 trillion floating point operations per second) levels of performance on real applications. Based on our Adaptive Supercomputing vision, our proposed system involves a new hybrid system architecture that combines multiple processor technologies, a new high-performance network and an adaptive software layer into a single integrated system designed to automatically match the most effective processor technology to each application. In addition to the final prototype demonstration, we will also perform a number of technology demonstrations throughout the program to demonstrate progress in key areas that the prototype system is dependent on. We will own the prototype system and will provide our mission partners access to the prototype system for a period of six months following the demonstration of the prototype system pursuant to the last milestone of the DARPA program.

The program is milestone-based. For each milestone, we meet with DARPA and its mission partners and provide information regarding the status of our development efforts to date. Each milestone has specific requirements for information and deliverables that we are to provide and specified minimum exit criteria demonstrating that we are making required progress towards completion of the prototype system. Based on our submissions and presentations at each milestone meeting, DARPA and its mission partners may request that we provide additional or supplemental information. DARPA provides a formal acceptance of each milestone, which is required for us to invoice for the DARPA payment associated with the particular milestone.

Before the recent amendment, we had met three milestones and had received a total of $62,500,000 in payments from DARPA; the following milestones remain, with the final milestone now scheduled for August 2012. The remaining milestones and associated payments are:

                    Minimum
                  Cumulative
                     Total
    Milestone      Spending        Government Share     Schedule      Event

    4           $ 104,166,667     $      25,000,000     Nov-2008      Project Review
    5           $ 145,833,333     $      25,000,000     Feb-2009      Project Review
    6           $ 187,500,000     $      25,000,000     Sep-2009      Project Review
    7           $ 229,166,667     $      25,000,000     Apr-2010      Project Review
    8           $ 270,833,333     $      25,000,000     Dec-2010      Project Review
    9A          $ 295,833,333     $      15,000,000     Mar-2011      Project Review
    9B          $ 312,500,000     $      10,000,000     Aug-2011      Project Review
     10         $ 375,000,001     $      37,500,000     Aug-2012      Final Demonstration

    Total       $ 375,000,001     $     250,000,000

The Cumulative Total Spending is the sum of the government's share and our cumulative contribution to Phase III. We report the actual Cumulative Total Spending to DARPA 30 days prior to each scheduled milestone review. If the spending is less than the Minimum Cumulative Total Spending threshold, we are to estimate a date when the spending threshold will be met. Based on this estimate, DARPA may delay the milestone review until after the spending threshold is achieved.

There was no change to the overall commitment by DARPA to deliver up to $250 million to us pursuant to this program, payable over all of the milestones, nor any change in our obligation to spend at least one-third of the total programming spending, including the amounts provided by the DARPA payments. Overall, we anticipate spending in excess of the minimum required amount to complete the program.

The parties mutually may modify the terms of the agreement and, if funding is available and research opportunities reasonably warrant, may extend the term of the agreement. Either DARPA or we may terminate the agreement based on a reasonable determination that the program will not produce beneficial results commensurate with the expenditure of resources. Any such termination must be preceded by consultation between DARPA and us. DARPA's future financial commitments are subject to subsequent Congressional action, and we are not obligated to continue work on this project beyond the point that DARPA obligates funds to this program. The recent amendment did not change these rights or obligations.

We have met the minimum cumulative total spending requirement for Milestone 4. While we expect to complete Milestone 4 in the fourth quarter of 2008, it is possible that DARPA acceptance of Milestone 4 could be delayed until 2009. In such event, our net research and development expense for the fourth quarter of 2008 would increase by $10 million over the amount currently anticipated, with a similar decrease in net research and development spending reported for the quarter in which the Milestone is accepted.

This Current Report contains forward-looking statements. There are certain factors that could cause actual results to differ materially from those anticipated by the statements above. See "Risk Factors" in our most recent Quarterly Report on Form 10-Q filed with the SEC.
