LIFE SUPPORT POLICY

FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT

OF FAIRCHILD SEMICONDUCTOR CORPORATION. As used herein:

1.

Life support devices or systems are devices or systems which, (a) are intended for

surgical implant into the body, or (b) support or sustain life, and (c) whose failure to

perform when properly used in accordance with instructions for use provided in the

labeling, can be reasonably expected to result in a significant injury of the user.

2.

A critical component in any component of a life support device or system whose failure

to perform can be reasonably expected to cause the failure of the life support device or

system, or to affect its safety or effectiveness.
