Explanation of Responses:

1. Effective as of June 28, 2013 (the "Distribution Date"), Covidien plc ("Covidien") completed the separation of the pharmaceuticals business of Covidien (the "Business") from the rest of Covidien by means of the declaration of a dividend in specie of the Business, effected by the transfer of the Business from Covidien to Mallinckrodt plc and the issuance by Mallinckrodt plc of ordinary shares in its share capital, par value $0.20 per share, credited as fully paid directly to Covidien's shareholders (the "Transaction"). Immediately following completion of the Transaction, Mallinckrodt plc acquired the seven ordinary shares [and 40,000 ordinary A shares] held beneficially by Enceladus Holding Limited for no consideration in accordance with the Irish Companies Acts and cancelled such shares.
