The team at PLC is committed to expanding the use of RenalGuard technology to prevent the onset of contrast-induced nephropathy (CIN) for at-risk patients.  We continue to focus our efforts on expanding the use of RenalGuard outside of the U.S. while at the same time continuing our pivotal trial with the U.S. FDA. With this additional equity financing, we anticipate having sufficient working capital into early 2014 while continuing to enroll patients in our pivotal U.S. clinical trial.

In connection with this financing, the outstanding Senior Secured Convertible Debt has been re-priced to $0.06 per share, and future interest payments have been suspended.
