 9.11 Special Provision Regarding Licenses. The License Agreement and any licenses contained in the Development and Supply Agreement shall not be deemed to be integrated with the other

should be

rejected in the future pursuant to § 365 and Hansen or Luna, as applicable, makes any election to retain rights and licenses under § 365(n)(1)(B); and (ii) require payment of
any royalties by Hansen or Luna, as applicable, under § 365(n)(2)(B). For avoidance of any doubt, notwithstanding any other provision of any Settlement Document, the result of the exception to integration of such contracts is that Hansen or
Luna, as applicable, shall be entitled to make its § 365(n)(1)(B) election to retain rights under a rejected License Agreement or with respect to licenses in the Development and Supply Agreement without impairing, affecting or prejudicing any
of Hansen’s or Luna’s, as applicable, rights, defenses, claims or interests of any kind, including setoff or recoupment, under or with respect to any other Settlement Document and without Hansen or Luna, as applicable, being required to
pay any amount as deemed “royalties” under such retained rights (since there shall be none). 
 9.12 Execution

counterparts, taken together, shall constitute one and the same agreement, which shall be binding and effective on the Parties hereto. This Agreement shall not become binding on the Parties hereto unless it has been executed by authorized
representatives of all Parties.
