PALA shall use commercially reasonable efforts to deliver the final, CSI-approved CSI Facebook

Application no later than July 31, 2014; and CST acknowledges that its feedback on such CSI Facebook Application development shall be in a timely fashion and that PALA's obligation to meet such timelines is conditional upon receiving such timely feedback.
