The Agent will promptly notify the Company in the event the Agent becomes aware of any of the following events: alleged infringement of the Trademarks by any third party; alleged infringement of the trademark or proprietary rights of others in connection with actions taken hereunder; liability claims relating to the Products and any other event that may reasonably be expected to have a material adverse effect upon the sale or distribution of the Products in the Territory. 3.5. Indemnification.
