Dear Ms. Krett: As we discussed, in preparing the public version of Plaintiff Power Integration's Opening Brief In Support of Its Post-trial Motion for Entry of a Permanent Injunction (D.I. 565) we discovered that the Table of Authorities was not correct. A corrected copy of the brief, which was filed under seal, on October 17, 2007 is being delivered to the Court for substitution. No other change was made to this brief. The redacted version, which will be filed shortly, will reflect the corrected Table of Authorities. Please accept our apologies for this error. Respectfully,

KWC/kxk Enclosure (2 copies of under seal brief) cc: Steven J. Balick, Esq., (w/corrected Table of Authorities) (By email) Bas de Blank, Esq. (w/corrected Table of Authorities) (By email) G. Hopkins Guy, III, Orrick, Herrington & Sutcliffe, LLP
