Dear Valued Customer,

It is with great pleasure that we would like to inform you that Isologic has a new
product within its portfolio.

We are introducing Antimony Sulfide Colloid Tc99m injection. This product is indicated
for use as an agent for lymphoscintigraphy and for the localization of lymphatic
drainage.

Do not hesitate to contact us or your local Radiopharmacy should you have any questions.

Cordially,
