all available information and assistance; and (iv) has not compromised or
settled such claim.

or specifications of Customer; (iii) modification of products, services or
technical data; or (iv) use of an allegedly infringing version of any products,
services or technical data, if the alleged infringement could be avoided by use

Customer for claims of infringement.
