NI STILL PROHIBITS THE USE OF ALL PRODUCTS IN SAFETY INSTRUMENTED USES RELATED TO NUCLEAR FISSION, AIR-TRAFFIC CONTROL, AIRCRAFT NAVIGATION, AND/OR IMBEDDED CLASS III MEDICAL DEVICES AS THOSE APPLICATIONS CONTINUE TO BE PROHIBITED HIGH-RISK USES. 
PRIOR TO USING THE DEVELOPED SAFETY LOGIC IN AN ALLOWABLE SAFETY INSTRUMENTED USE, YOU ARE RESPONSIBLE FOR (I) DETERMINING WHETHER THE PRODUCT WITH WHICH YOU ARE USING THE DEVELOPED SAFETY LOGIC IS SIL CERTIFIED BY REVIEWING THE PRODUCT DOCUMENTATION; (II) determining whether the safety logic developed by the Software is suitable for use in your SIFS or SIS'; (III) COMPLYING WITH THE SOFTWARE SPECIFICATIONS AND FUNCTIONAL SAFETY MANUAL; AND (IV) ENSURING THAT YOUR SIFS AND SIS' THAT UTILIZE THE DEVELOPED safety logic MEET THE FUNCTIONAL SAFETY SYSTEM REQUIREMENTS SET FORTH IN THE FUNCTIONAL SAFETY MANUAL. YOU REMAIN RESPONSIBLE FOR TAKING ALL PRUDENT STEPS TO PROTECT AGAINST PRODUCT AND SYSTEM FAILURES, INCLUDING PROVIDING BACK-UP AND SHUT-DOWN MECHANISMS.
NI EXPRESSLY DISCLAIMS ANY EXPRESS OR IMPLIED WARRANTY OF FITNESS OF THE SOFTWARE FOR PROHIBITED HIGH-RISK USES OR SAFETY INSTRUMENTED USES. YOU SHALL DEFEND, INDEMNIFY, AND HOLD NI HARMLESS FROM ANY AND ALL CLAIMS, LOSSES, DAMAGES, ACTIONS (INCLUDING LAWSUITS, ARBITRATIONS, AND ADMINISTRATIVE ACTIONS), AND EXPENSES (INCLUDING ATTORNEYS' FEES AND EXPENSES OF COUNSEL OF NI'S SOLE CHOOSING) DIRECTLY OR INDIECTLY ARISING OUT OF YOUR USE OF THE SOFTWARE FOR PROHIBITED HIGH-RISK USES OR SAFETY INSTRUMENTED USES, INCLUDING CLAIMS FOR PRODUCT LIABILITY, NEGLIGENCE, GROSS NEGLIGENCE, PERSONAL INJURY, DEATH, OR DAMAGE TO PROPERTY, REGARDLESS OF WHETHER SUCH CLAIMS ARE FOUNDED IN WHOLE OR IN PART UPON ALLEGED OR ACTUAL NEGLIGENCE OR GROSS NEGLIGENCE OF NI.
3. The terms of this Product Addendum (i) are incorporated into, and part of, the License Agreement and (ii) only apply to the National Instruments SOFTWARE products identified above in the title of this Product Addendum. To the extent there is any conflict between the terms of this Product Addendum and the License Agreement, as such terms apply to the SOFTWARE products identified above, this Product Addendum shall control.
