Explanation of Responses:

1. This amendment is being filed to correct errors in the August 18, 2014 Form 4 for the reporting person. On August 14, 2014, Mallinckrodt plc ("Mallinckrodt") acquired Questcor Pharmaceuticals, Inc. ("Questcor") pursuant to the Agreement and Plan of Merger, dated as of April 5, 2014, by and among Mallinckrodt, Questcor and Quincy Merger Sub, Inc. (the "Merger"). In connection with the Merger, at the effective time of the Merger (the "Effective Time"): (i) each share of Questcor common stock (except for certain shares defined in the Merger Agreement) and each outstanding share of restricted Questcor common stock granted to a non-employee director converted to the right to receive, without interest, (a) $30.00 in cash and (b) 0.897 of an ordinary share of Mallinckrodt (together, the "Merger Consideration"), in exchange for such share of Questcor common stock or such restricted common stock; and

2. (ii) each outstanding option to purchase Questcor common stock granted to a non-employee director (whether vested or unvested) converted into the right to receive the Merger Consideration with respect to each share of Questcor common stock subject to such option immediately prior to the Effective Time, net of the applicable exercise price. The number of Mallinckrodt ordinary shares acquired by the reporting person as a result of the conversion of Questcor common stock and restricted stock reported on the original Form 4 incorrectly included 9,157 ordinary shares; the correct number is 7,501 ordinary shares. The number of Mallinckrodt ordinary shares acquired by the reporting person as a result of the conversion of vested or unvested stock options, net of applicable exercise price reported on the original Form 4 incorrectly included 12,373 ordinary shares; the correct number is 6,130 ordinary shares.
