definiens: shall mean that Purchaser has achieved a level of competence in which it can, [ without the assistance of Seller, using commercially reasonable efforts and good scientific and laboratory practice ] : ( a ) create [ two ( 2 ) Transfluor - Enabled Cell Lines, each incorporating a different GPCR specified on Exhibit B, one of which shall be an Orphan Receptor and one of which shall be a GPCR having one or more Known Ligands ], provided that [ ( i ) one of the two such GPCRs shall be a pit - forming receptor, ( ii ) both such Transfluor - Enabled Cell Lines shall be created from the same, single Transfluor Starter Cell Line, and ( iii ) neither of such Transfluor - Enabled Cell Lines shall incorporate any of the GPCRs expressed by the two ( 2 ) additional Transfluor - Enabled Cell Lines provided by Seller pursuant to Section 1.7(b ) below ] ; ( b ) use [ the Transfluor - Enabled Cell Line incorporating the beta2 - adrenergic receptor created pursuant to Section 1.7(a ) and the U20S - V2R - barrestin2 - RrGFP and U20S­MOR - barrestin2 - RrGFP cell lines ( containing the vasopressin 2 receptor and mu - opioid receptor, respectively ) ( collectively, all three ( 3 ) cell lines, the ), each of which latter two Transfluor - Enabled Cell Lines shall be provided by Seller, in the Transfluor Assay to reproducibly and consistently generate the same quality of data generated by Seller on the IN Cell Analyzer 3000 in the Transfluor Assay using Transfluor - Enabled Cell Lines incorporating the same GPCRs and GFPs ], provided that [ ( i ) Purchaser shall perform such Transfluor Assays ' protocols finishing with fixed plates of cells in order to permit Seller to analyze such cells itself in the event Purchaser is unable to generate the same quality of data as described herein and ( ii ) Purchaser shall permit Seller to perform the Transfluor Assay on such fixed plates in such event for purposes of confirming such results and providing further assistance as may be required pursuant to the terms of this Agreement ] . Purchaser 's ability to use the [ Transfluor - Enabled Cell Lines ] as described in this Section 1.7(b ) shall [ include the ability, without limitation, to ( A ) run the Transfluor Assay with respect to the U20S - V2R - barrestin - RrGFP cell line to identify a DAC as a DAC among several non - DAC compounds to be provided by Seller in form, ( B ) run the Transfluor Assay with respect to the U20S - MOR - barrestin - RrGFP cell line to identify an NDL as an NDL among several non - NDL compounds to be provided by Seller in form, ( C ) perform the LITe Assay with respect to GPR55, and ( iii ) transform a pit - forming cell line into a vesicle - forming cell line by transient transfection of a Tail Modified GPCR, provided that ( 1 ) the DAC and NDL provided by Seller for purposes of ( A ) and ( B ) above are proprietary and confidential to Seller, ( 2 ) no rights except those necessary for purposes of Purchaser establishing Minimal Competence under this Agreement are in any fashion granted or assigned to MDC with respect to such DAC or NDL as part of the Transactions, ( 3 ) such DAC, NDL, and I : 1 = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, IS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED
