Infringement Claims by Third Parties. If either # any Licensed Product Developed, made, Commercialized or otherwise exploited by or under authority of Arcus becomes the subject of a Third Party’s claim or assertion of infringement of a patent relating to the manufacture, use, sale, offer for sale or importation of such Licensed Product in the Field in the Territory, or # if a declaratory judgment action is brought naming either Party as a defendant and alleging invalidity of any of the Licensed Patents, the Party first having notice of the claim or assertion shall promptly notify the other Party, and the Parties shall promptly confer to consider the claim or assertion and the appropriate course of action. Unless the Parties otherwise agree in writing, each Party shall have the right to defend itself against a suit that names it as a defendant (the “Defending Party”). If Abmuno is named in such legal action but not Arcus, then Arcus shall have the right to join, at its own expense, any such legal action and to be represented in such action by its own counsel. None of the Parties shall enter into any settlement of any claim described in this Section that admits to the invalidity, narrowing of scope or unenforceability of the Licensed Patents or this Agreement, incurs any financial liability on the part of the other Party or requires an admission of liability, wrongdoing or fault on the part of the other Party without such other Party’s prior written consent. In any event, the other Party shall reasonably assist the Defending Party and cooperate in any such litigation at the Defending Party’s cost and the Defending Party shall reimburse the other Party’s reasonable out-of-pocket costs associated therewith.
