Design a Powerpoint template

A client has recently rebranded but their website has NOT been re-launched. as part of the re-brand we need to put together an engaging power point template. I am attaching 2 power point files. 1 file is an initial stab at a template but it is not engaging. The second file is their original power point template with the old branding. We need to #1: create an engaging template but professional (they sell to large companies) nice title page, leverage their corporate branding of the "bucky ball). Secondly #2: move all the slides over from the original deck but clean them up in the process re-layout the images, re-color them, transpose text. I've also attached brand guidelines and the bucky balls.
