to the publication hereof.

Suitability for use

 — NXP Semiconductors products are not designed,

authorized or warranted to be suitable for use in life support, life-critical or

safety-critical systems or equipment, nor in applications where failure or

malfunction of an NXP Semiconductors product can reasonably be expected

to result in personal injury, death or severe property or environmental

damage. NXP Semiconductors and its suppliers accept no liability for

inclusion and/or use of NXP Semiconductors products in such equipment or

for the specified use without further testing or modification. Customers

are responsible for the design and operation of their applications and

products using NXP Semiconductors products, and NXP Semiconductors

accepts no liability for any assistance with applications or customer product

design. It is customer’s sole responsibility to determine whether the NXP

Semiconductors product is suitable and fit for the customer’s applications

and products planned, as well as for the planned application and use of

customer’s third party customer(s). Customers should provide appropriate

design and operating safeguards to minimize the risks associated with

their applications and products. NXP Semiconductors does not accept any

liability related to any default, damage, costs or problem which is based

on any weakness or default in the customer’s applications or products, or

the application or use by customer’s third party customer(s). Customer is

responsible for doing all necessary testing for the customer’s applications

and products using NXP Semiconductors products in order to avoid a

default of the applications and the products or of the application or use by

customer’s third party customer(s). NXP does not accept any liability in this

respect.

that customer might incur for any reason whatsoever (including without

limitation, all damages referenced above and all direct or general damages),

the entire liability of NXP Semiconductors, its affiliates and their suppliers

and customer’s exclusive remedy for all of the foregoing shall be limited to

actual damages incurred by customer based on reasonable reliance up to

the greater of the amount actually paid by customer for the product or five

dollars (US$5.00). The foregoing limitations, exclusions and disclaimers

shall apply to the maximum extent permitted by applicable law, even if any
