Other Actions by Third Parties. Each Party will promptly notify the other Party in the event of any legal or administrative action by any Third Party involving any Licensed Patent Rights of which it becomes aware, including any nullity, revocation, interference, reexamination, inter partes review, post grant review or compulsory licensing proceeding. Axsome will have the first right, but not the obligation, to defend against any such action involving any Licensed Patent Rights, in its own name or Licensee’s name (to the extent permitted by Applicable Law), and any such defense will be at Licensee’s expense. Licensee, at Axsome’s request, agrees to join in any such action at Licensee’s expense and in any event to cooperate with Axsome at Licensee’s expense. If Axsome fails to defend against any such action involving a Licensed Patent Right, then Licensee will have the right to defend such action, in its own name and at its own expense.

Third Party Infringement. Except as otherwise provided in this Section 5.5, Licensee will have the first right, but not the obligation, to institute litigation or take other steps to remedy Third Party Infringement, and any such litigation or steps will be at Licensee’s expense. Licensee will not, without the prior written consent of Axsome (such consent not to be unreasonably withheld, delayed or conditioned), enter into any compromise or settlement relating to such litigation that # admits the invalidity or unenforceability of any Licensed Patent Right, # requires that any Licensed Patent Right be abandoned or # otherwise adversely affects the rights or interest of Axsome or, if applicable with respect to such Licensed Patent Right, the Upstream Licensor of such Licensed Patent Right. In order to establish standing, Axsome, upon request of Licensee, agrees to timely commence or to join in any such litigation or to request that the applicable Upstream Licensor join in such litigation, in each case at Licensee’s expense, and in any event to cooperate with Licensee in such litigation or steps at Licensee’s expense. Axsome and any applicable Upstream Licensor will have the right to consult with Licensee about such litigation and to participate in and be represented by independent counsel in such litigation at Axsome’s expense. Any recoveries obtained by Licensee in connection with any such litigation or steps taken in relation to such infringement shall first be used to reimburse Licensee for the reasonable out-of-pocket costs incurred by Licensee in litigating such Third Party Infringement and the remainder, if any, shall be retained by Licensee for its own account, provided that # such recoveries treated as Net Sales in the Calendar Quarter in which they are received for all purposes under this Agreement.
