Following [COMPANY] ’s delivery of suchnotice, ( A ) the Parties shall mutually agree to an additional deuterated molecule, ( B ) shall mean such deuteratedmolecule, an isomer ( including stereoisomer ) or isotopologue thereof, a salt or solvate ( including hydrate ) of any of theforegoing, or a deuterated metabolite of any of the foregoing that is administered in a therapeutically effective amount;(C ) shall also include any solid forms, including any crystalline or amorphous forms, co - crystals, andpolymorphs of any 44compound of the foregoing ; and ( D ) [ * * ] Option Products shall be deemed added to the list of Licensed Products followingCelgene ’s exercise of the License Option with respect thereto . Notwithstanding the foregoing or anything to the contraryherein, if [COMPANY] provides written notice to Concert that [COMPANY] desires to exercise the License Option to select a deuteratedmolecule as [ * * ] Option pursuant to this Section 11.1.5(ii ), and at such time Concert does not have an existing program fromwhich Concert is willing to permit and [COMPANY] is willing to accept the selection of a deuterated molecule as [ * * ] Option, theParties shall in good faith seek to identify by mutual agreement a new program pursuant to which Concert would seek togenerate a deuterated molecule for designation as [ * * ] Option
