Critical Applications. Products are not authorized for use in applications in which failure of the Micron compo-

nent could result, directly or indirectly in death, personal injury, or severe property or environmental damage

("Critical Applications"). Customer must protect against death, personal injury, and severe property and environ-

mental damage by incorporating safety design measures into customer's applications to ensure that failure of the

Micron component will not result in such harms. Should customer or distributor purchase, use, or sell any Micron

component for any critical application, customer and distributor shall indemnify and hold harmless Micron and

its subsidiaries, subcontractors, and affiliates and the directors, officers, and employees of each against all claims,

costs, damages, and expenses and reasonable attorneys' fees arising out of, directly or indirectly, any claim of

applications, and products using Micron products. ALL SEMICONDUCTOR PRODUCTS HAVE INHERENT FAIL-

URE RATES AND LIMITED USEFUL LIVES. IT IS THE CUSTOMER'S SOLE RESPONSIBILITY TO DETERMINE

WHETHER THE MICRON PRODUCT IS SUITABLE AND FIT FOR THE CUSTOMER'S SYSTEM, APPLICATION, OR

PRODUCT. Customers must ensure that adequate design, manufacturing, and operating safeguards are included

in customer's applications and products to eliminate the risk that personal injury, death, or severe property or en-

vironmental damages will result from failure of any semiconductor component.

Limited Warranty. In no event shall Micron be liable for any indirect, incidental, punitive, special or consequential
