Dear Ms. Krett: As we discussed with your office, in preparing the public version of the Declaration of William J. Marsden, Jr. In Support of Plaintiff Power Integration's Answering Brief In Opposition to Fairchild's Post-trial Brief Asserting Inequitable Conduct (D.I. 604) we discovered that the text of the Declaration referred to Kyle Wagner Compton instead of William J. Marsden, Jr. and the removal of the second 1. was removed from paragraph no. 1 A corrected copy of the declaration, which was filed under seal, on November 28, 2007 is being delivered to the Court for substitution. No other change was made to this declaration. The redacted version, which will be filed shortly, will reflect the corrected page 1. Please accept our apologies for this error. Respectfully,

WJM/kxk Enclosure (2 copies of under seal declaration) cc: Steven J. Balick, Esq., (w/corrected page of declaration) (By email) G. Hopkins Guy, III, Esq. (w/corrected page of declaration) (By email)
