Dear Ms. Higgins:
I am sending this letter to formally notify you that Mallinckrodt plc will be a new public company
effective after receipt of government approvals anticipated in June 2013. Mallinckrodt LLC will
continue to conduct its US operations and is the current legal entity holding all existing
environmental permits, general permits, licenses and registrations applicable to our facility located
at 8801 Capital Boulevard in Raleigh. The direct parent company of Mallinckrodt LLC is
Mallinckrodt Enterprises LLC, a Delaware limited liability corporation. Both companies are
ultimately owned by Mallinckrodt plc.
Mallinckrodt plc will formally become a publicly traded entity upon approval of the Form 10
Registration statement filed with the US Securities and Exchange Commission (SEC) on February
1, 2013. The anticipated date for the completion of this process is June 28, 2013. This notification
is to inform you of the new independent status of Mallinckrodt LLC's ultimate parent company.
This action does not involve any transfer of property or change to the corporate structure of
Mallinckrodt LLC and all permits and licenses will remain in the name of Mallinckrodt LLC. Please
note that the ownership of the property remains the same.
If you have any further questions or require any additional information please contact me at
