Automotive Applications. Products are not designed or intended for use in automotive applications unless specifi-
cally designated by Micron as automotive-grade by their respective data sheets. Distributor and customer/distrib-
utor 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
non-automotive-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 compo-
nent for any critical application, customer and distributor shall indemnify and hold harmless Micron and its subsid-
iaries, 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 envi-
ronmental 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
