and customer/distributor shall assume the sole risk and liability for and shall indemnify and hold Micron

harmless against all claims, costs, damages, and expenses and reasonable attorneys' fees arising out of,

directly or indirectly, any claim of product liability, personal injury, death, or property damage resulting

directly or indirectly from any use of nonautomotive-grade products in automotive applications.

Customer/distributor shall ensure that the terms and conditions of sale between customer/distributor and

any customer of distributor/customer (1) state that Micron products are not designed or intended for use

in automotive applications unless specifically designated by Micron as automotive-grade by their

respective data sheets and (2) require such customer of distributor/customer to indemnify and hold

Micron harmless against all claims, costs, damages, and expenses and reasonable attorneys' fees

arising out of, directly or indirectly, any claim of product liability, personal injury, death, or property

damage resulting from any use of non-automotive-grade products in automotive applications.

Critical Applications.

Products are not authorized for use in applications in which failure of the Micron

component 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 environmental 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 product liability,

personal injury, or death arising in any way out of such critical application, whether or not Micron or its

subsidiaries, subcontractors, or affiliates were negligent in the design, manufacture, or warning of the

Micron product.

Customer Responsibility.

Customers are responsible for the design, manufacture, and operation of

their systems, applications, and products using Micron products. ALL SEMICONDUCTOR PRODUCTS

HAVE INHERENT FAILURE 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 environmental 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 damages (including without limitation lost profits, lost savings, business interruption, costs

related to the removal or replacement of any products or rework charges) whether or not such damages

are based on tort, warranty, breach of contract or other legal theory, unless explicitly stated in a written

agreement executed by Micron's duly authorized representative.
