                Mallinckrodt Pharmaceuticals Announces Clinical And Commercial Collaboration With Medtronic
                
      Collaboration agreement will focus on furthering pre-clinical,
      clinical and commercial aspects of intrathecal therapeutics
    
    ST. LOUIS, Mo.--(BUSINESS WIRE)--Jan. 13, 2014--
      Mallinckrodt
      (NYSE: MNK) announced today that it has entered into a multiyear
      agreement with Medtronic
      (NYSE: MDT) to advance availability in the U.S. of intrathecal
      therapeutics for the treatment of chronic pain and severe spasticity.
    
      Under the agreement, the two companies will collaborate on the
      development and testing of Mallinckrodt’s future intrathecal products
      for use in Medtronic’s SynchroMed® Programmable Infusion
      System. The companies will also develop joint marketing and sales
      programs to increase awareness and adoption of these drug delivery
      therapies. Specific terms of the agreement are not being disclosed.
    
      Intrathecal therapeutics use an implanted pump to deliver very small
      quantities of medications directly to a patient’s spinal fluid. Since
      this kind of “targeted drug delivery” system combines the use of a
      medical device with a pharmaceutical agent, the development path can be
      longer than that for either device or drug alone. This collaboration is
      intended to accelerate innovation and expand clinician and patient
      education regarding targeted delivery of drugs for the management of
      chronic disease.
    
      “This collaboration will allow each organization to leverage their
      respective strengths – Mallinckrodt in specialty pharmaceuticals and
      Medtronic in implantable drug delivery technology,” said Mark Trudeau,
      President and Chief Executive Officer, Mallinckrodt. “Together, we will
      focus on advancing the development and delivery of therapeutic agents to
      serve patients suffering from chronic pain or severe spasticity. We are
      excited about the future of our intrathecal product line, and this
      agreement will enable us to deliver meaningful solutions to this market.”
