Licensor hereby grants to Sublicensee all of the rights and licenses granted to Sublicensee by Sublicensor hereunder (including
the Licensed Science Sublicense). Sublicensee shall not exercise such rights and licenses unless and until a No-Fault Termination
Event has occurred and the Licensed Science Sublicense granted hereunder has been terminated. Notwithstanding anything to the contrary
in this Agreement or the License Agreement (including Section 5 thereof), upon the occurrence of a No-Fault Termination Event
resulting in the termination of the License Agreement, the termination of this Agreement or the dissolution of the Sublicensor
(as applicable), Sublicensee may exercise the rights and licenses set forth in this Section 4.3 and Licensor will assume all
obligations of Sublicensor in this Agreement, both without any further action by any of the Parties.

and agree that the Intellectual Property rights licensed to Sublicensee hereunder constitute “intellectual property”

this Agreement or the License Agreement, with respect to such rights (including any embodiment of the rights to the extent protected
by applicable non-bankruptcy law), as such rights existed immediately before the Sublicensor’s and/or Licensor’s bankruptcy
case commenced. If Sublicensee elects to retain such licensed rights under this Agreement or the License Agreement, then Sublicensee

Pursuant to the Master License Agreement, it shall be the obligation of Licensor, at its sole

of the Patents pursuant to the terms of the Master License Agreement. If pursuant to the Master License Agreement the Licensor
determines not to diligently enforce the Patents, (in which case Licensor shall promptly notify Sublicensor in writing of the same,

of Licensor and other licensees of the Patents (i) Sublicensee will have the right to enforce the Patents at Sublicensee’s
sole expense, (ii) if requested by Sublicensee, Licensor and Sublicensor will cooperate in Sublicensee’s prosecution
or defense of any dispute resolution, litigation or settlement activities hereunder, provided that Sublicensee will reimburse Licensor
for all reasonable costs incurred by Licensor as a result of such cooperation, and (iii) any recoveries will be awarded to
Sublicensor and Sublicensee (and any other participating licensees or sublicensees) in an amount that is proportional to their
costs in so enforcing the Patents.
