Section 6. Liability; Indemnification. -------------------------- (a) IDT shall have no liability whatsoever to Net2Phone for any error, act or omission in connection with the services to be rendered by IDT to Net2Phone hereunder unless any such error, act or omission derives from willful misconduct or gross negligence.
