consummating the deal in the near future."

immediately accretive to earnings and it fits within our broader strategy to
grow Paladin's revenues beyond the Canadian border."

ABOUT MILTEFOSINE

Miltefosine is a phosphocholine analogue currently marketed under the brand name
Impavido(R), the first oral drug for the treatment of visceral and cutaneous
leishmaniasis. Impavido(R) has been proven to be highly effective and less toxic
than current therapies. Other current available treatments are liposomal
amphotericin (Ambisome(R)) and Paromomycin.

ABOUT LEISHMANIASIS

Leishmaniasis is an infectious disease transmitted by the bite of the
phlebotomine sandfly. The cutaneous form of the disease normally produces skin
ulcers on the exposed parts of the body such as the face, arms and legs. The
visceral form - also



known as kala azar - is characterized by irregular bouts of fever, substantial
weight loss, swelling of the spleen and liver, and anemia (occasionally
serious).

According to the World Health Organization, the disease is endemic in 88
countries with nearly 350 million people at risk. If untreated, visceral
leishmaniasis can result in death within 6 months to 2 years. There are more
than one million new cases per year of cutaneous leishmaniasis and an estimated
prevalence of 12 million people already infected.
