ENDOCARDIAL SOLUTIONS

Endocardial Solutions, Inc. ("ESI" or the "Company") designs, develops, and manufactures a minimally invasive diagnostic system that diagnoses, within the span of a few heartbeats, tachycardia, a potentially fatal abnormal heart rhythm. The Company believes that its proprietary EnSite catheter and clinical workstation (together, the "EnSite System") is a powerful new diagnostic tool that will enable electrophysiologists to rapidly and comprehensively map tachycardia and improve the selection of patient treatment options.
