definiens: means, on a Research Program -by - Research Program basis, the delivery by [COMPANY] to Cullinan of [ * * * ] for such Research Program . For clarity, if there are multiple deliveries of sequences of Program Antibodies during the course of a Research Program ( e.g., one delivery with respect to the Program Antibodies generated through the initial discovery process and a subsequent delivery of sequences of Program Antibodies with respect to optimization of the initially delivered Program Antibodies into new, optimized Program Antib odies ), then Final Delivery shall mean only the last of such deliveries ; provided, however, that in the event that [ * * * ] passes from the most recent delivery of Program Antibodies from [COMPANY] to Cullinan under a Research Program and Cullinan has not submit ted a list of Program Antibodies for additional work ( e.g., optimization ) with respect to such Research Program, then such delivery will be deemed to be the Final Delivery under such Research Program, even if the possibility exists that [COMPANY] will perform additional work with respect to such Research Program ( and even if [COMPANY] actually subsequently performs additional work with respect to such Research Program )
