Life Support Application
Seller's Products are not designed, intended, or authorized for use as components in systems intended for space,
aviation, surgical implant into the body, in other applications intended to support or sustain life, or for any other
application in which the failure of the Seller's Product could create a situation where personal injury, death or property
damage or loss may occur (collectively "Life Support Applications").
Buyer agrees not to use Products in any Life Support Applications and to the extent it does it shall conduct extensive
testing of the Product in such applications and further agrees to indemnify and hold Seller, and its officers, employees,
subsidiaries, affiliates, agents, sales representatives and distributors harmless against all claims, costs, damages and
expenses, and attorneys' fees and costs arising, directly or directly, out of any claims of personal injury, death, damage
or otherwise associated with the use of the goods in Life Support Applications, even if such claim includes allegations
that Seller was negligent regarding the design or manufacture of the goods.
Buyer must notify Seller in writing before using Seller’s Products in Life Support Applications. Seller will study with
Buyer alternative solutions to meet Buyer application specification based on Sellers sales conditions applicable for the
new proposed specific part.
