definiens: . CNS means the central nervous system . [ * * * ] 1.20 . The CNS Term means the period begi nning on the New CLA Effective Date and ending on the later of ( a ) [ * * * ] ( [ * * * ] ) years from the date of initiation of work under the Resea rch Plan for CNS, and ( b ) the date on which 4DMT delivers [ * * * ] ( [ * * * ] ) ( i.e., when it has delivered [ * * * ] ) New CNS Variants to [COMPANY] with the Vector Characterizatio n Data with respect to each of such [ * * * ] ( [ * * * ] ) N ew CNS Variants that the Research Plan for CNS requires 4D MT to provide . It is understood that the Selection Processes giving rise to such New CNS Variants shall be the S election Processes directed at identifying CNS - targ eted variants as defined and called for in the Research Plan, or, if such Selection Processes do not yield [ * * * ] ( [ * * * ] ) New CNS Variants meeting the Delivery Success Crite ria ( that can then proceed into the studies that ge nerate Vector Characterization Data in accordance with the Research Plan for CNS ), then Selection Processes f or CNS - targeted AAV Capsid Variants that 4DMT conducts in addition or as follow - ups to ( but in each case not in replacement or in lieu of ) such CNS - directed Select ion Processes called for in the Research Plan, and in any event meeting the requirements of Section 3.1 . If 4 DMT conducts such in - addition - to and/or follow - up C NS - directed Selection Processes, then the Vector Chara cterization Data that 4DMT would have to report to [COMPANY] in order for the applicable New CNS Variants to cou nt as one of the [ * * * ] ( [ * * * ] ) New CNS Variants of clause ( b ) of the first sentence of this definition, shall be equivalent to the Vector Characterization Data that 4DMT is required to report to [COMPANY] under the Research Pl an with respect to the New CNS Variants that it del ivers thereunder . [COMPANY] ’s information and input rights as to any such additional Selection Processes that 4DMT may choose to conduct are as provided for in Section 3 . 1
