FOR IMMEDIATE RELEASE

Lantheus Medical Imaging and Nordion
Extend Molybdenum-99 Supply Contract through 2015

No. BILLERICA, Mass. (October 22, 2012) — Lantheus Medical Imaging, Inc., a global leader in developing, manufacturing and distributing innovative diagnostic imaging agents, today announced that it has extended its contract with Nordion to supply molybdenum-99 (Mo-99) for use in its TechneLite® (Technetium Tc 99m Generator) generators. Mo-99 is the parent isotope of technetium-99m (Tc-99m), the medical radioisotope most widely used in nuclear medicine diagnostic imaging tests.

“As a leading provider of radioisotope generators, securing the supply of critical isotopes such as Mo-99 is of prime importance to the success of our business,” said Don Kiepert, President and Chief Executive Officer of Lantheus Medical Imaging. “Our amended contract with Nordion further solidifies our globally diversified sourcing of Mo-99, which reinforces our ongoing commitment to provide a stable, balanced and reliable supply to our customers.”

“One of Nordion’s key priorities is providing a continuous supply of medical isotopes to meet the needs of the global medical community, and the extension of our Mo-99 supply contract with Lantheus further advances this objective,” said Steve West, Chief Executive Officer, Nordion. “We value the ongoing relationship with Lantheus and are focused on identifying new isotope sources to provide a stable supply chain for our partners worldwide.”

About Molybdenum-99 and Technetium-99m

Mo-99 is the parent isotope of technetium-99m (Tc-99m), which is the radioisotope most widely used for nuclear medicine diagnostic imaging tests. Tc-99m is a critical component of many medical tests, including scans of the heart, brain, kidneys and some types of tumors. Tc-99m is used in Lantheus Medical Imaging’s TechneLite® generators, which are distributed to hospitals

and radiopharmacies as a source of Tc-99m for diagnostic imaging procedures. Tc-99m is also used with Cardiolite® (Kit for the Preparation of Technetium Tc 99m Sestamibi for Injection), the most successful radiopharmaceutical agent, which has been used to image more than 40 million patients.(1) In diagnostic use, Tc-99m is attached to a specific molecule and injected into the patient, where it emits gamma radiation that can be used to produce an image of the region.
