Hynix litigation update: On March 10, 2009, the court entered final judgment against Hynix in the amount of approximately $397 million as follows: approximately $134 million for infringement through December 31, 2005; approximately $215 million for infringement from January 1, 2006 through January 31, 2009; and approximately $48 million in pre-judgment interest. Post-judgment interest will accrue at the statutory rate. In addition, the judgment orders Hynix to pay Rambus royalties on net sales for U.S. infringement after January 31, 2009 and before April 18, 2010 of 1% for SDR SDRAM and 4.25% by DDR DDR2, DDR3, GDDR, GDDR2 and GDDR3 SDRAM memory devices. On April 9, 2009, Rambus submitted its cost bill in the amount of approximately $0.9 million. On March 24, 2009, Hynix filed a motion under Rule 62 seeking relief from the requirement that it post a supersedeas bond in the full amount of the final judgment in order to stay its execution pending an appeal. Rambus filed a brief opposing Hynix’s motion on April 10, 2009. A hearing on Hynix’s motion is scheduled for May 8, 2009. Execution of the judgment is stayed until two weeks after the hearing date or until such time as may otherwise be ordered by the court.
On April 6, 2009, Hynix filed its notice of appeal. On April 17, 2009, Rambus filed its notice of cross appeal. The parties’ opening briefs are not yet due.

On February 9, 2009, the court stayed all other proceedings pending appeal of the Delaware Order.
