1. Description of Business

Overview

Holdings, a Delaware corporation, is the parent company of LMI, also a Delaware corporation.

The Company develops, manufactures and commercializes innovative diagnostic medical imaging agents and products that assist clinicians in the diagnosis and treatment of cardiovascular and other diseases. The Company’s commercial products are used by cardiologists, nuclear physicians, radiologists, internal medicine physicians, technologists and sonographers working in a variety of clinical settings. The Company sells its products to radiopharmacies, hospitals, clinics, group practices, integrated delivery networks, group purchasing organizations and, in certain circumstances, wholesalers. The Company sells its products globally and has operations in the United States, Canada, Puerto Rico and Australia and distribution relationships in Europe, Asia Pacific and Latin America.

The Company’s portfolio of 10 commercial products is diversified across a range of imaging modalities. The Company’s imaging agents include contrast agents and medical radiopharmaceuticals (including technetium generators), including the following:

•

DEFINITY is the leading ultrasound contrast imaging agent used by cardiologists and sonographers during cardiac ultrasound, or echocardiography, exams based on revenue and usage. DEFINITY is an injectable agent that, in the United States, is indicated for use in patients with suboptimal echocardiograms to assist in the visualization of the left ventricle, the main pumping chamber of the heart. The use of DEFINITY in echocardiography allows physicians to significantly improve their assessment of the function of the left ventricle.

•

TechneLite is a self-contained system, or generator, of technetium (Tc99m), a radioisotope with a six hour half-life, used by radiopharmacies to prepare various nuclear imaging agents.

•

Xenon Xe 133 Gas, or Xenon, is a radiopharmaceutical gas that is inhaled and used to assess pulmonary function and also cerebral blood flow.

•

Cardiolite is an injectable, technetium-labeled imaging agent, also known by its generic name sestamibi, used with Single Photon Emission Computed Tomography, or SPECT, technology in myocardial perfusion imaging, or MPI, procedures that assess blood flow distribution to the heart.

•

Neurolite is an injectable, technetium-labeled imaging agent used with SPECT technology to identify the area within the brain where blood flow has been blocked or reduced due to stroke.

In the United States, the Company sells DEFINITY through its sales team that calls on healthcare providers in the echocardiography space, as well as group purchasing organizations and integrated delivery networks. The Company’s radiopharmaceutical products are primarily distributed through commercial radiopharmacies owned or controlled by third parties. In Puerto Rico and Australia, the Company owns three radiopharmacies and sells its own radiopharmaceuticals, as well as others, directly to end users. In Canada, Europe, Asia Pacific and Latin America, the Company utilizes distributor relationships to market, sell and distribute its products.
