AKSY Aksys, Ltd.

Aksys, Ltd. (Aksys) provides hemodialysis products and services for patients suffering from end-stage renal disease (ESRD), commonly known as chronic kidney failure. It has developed an automated personal hemodialysis system, known as the Aksys Personal Hemodialysis (PHD) System (the PHD System), which is designed to enable patients to perform frequent hemodialysis at alternate sites. Outpatient hemodialysis requires that a patient travel to a dialysis clinic three times per week for dialysis sessions lasting three to four hours. In each session, the patient's blood is cleansed by circulation through an artificial kidney controlled by a dialysis machine. Home hemodialysis involves treatment of patients in their homes. During the year ended December 31, 2005, the Company's largest customers were DaVita, the Dialysis Centers of Lincoln and Northwest Kidney Center, which accounted for 16%, 11% and 8%, respectively, of the revenues.
