    Amendment to Section2(a)(1)(2). Section 2(a)(1)(2) is hereby

available to Akorn for pickup [***...***]doses in single dose
vials (the Replacement Doses) in consideration of Akorns
timely payment of the first installment of the Year 1
Resolution Amount (as such term is defined in Section
2 (a)(3) (Akorn Resolution Payment) below). Of the
Replacement Doses, Akorn will pick up [***...***]doses on or
before August 15, 2008, and the remainder of the
Replacement Doses on or before September 30, 2008.
Dating for Replacement Doses will be no less favorable than

conflict between the terms of this Second Amendment and the
terms of the Modified Agreement, the terms of this Second
Amendment shall control.

the terms of this Second Amendment, all the terms, conditions,
