NOW, THEREFORE, PLEASE TAKE NOTICE THAT, pursuant to Fed. R.
Civ. P. 41(a)(l), Plaintiffs hereby dismiss Count I of their Complaint, without prejudice. This
dismissal is without waiver of or other prejudice to Plaintiffs’ contentions that Impax’s prior
Paragraph IV Notices (Le., those that Plaintiffs received prior to December 14, 2007) are null,
void and without legal effect. Plaintiffs are maintaining their claim for patent infringement
‘ based on Impax’s pre-December 14, 2007 Paragraph IV Notices because Impax has refused to
withdraw such Notices and continues to take the position that such Notices are valid. Plaintiffs
will file a claim for infringement based on the December 14, 2007 Notice within the prescribed
45 day period.
