1. The justification letter from the vendor is not acceptable since the content does not state that the previous model Bioscrypt 4G V-station is obsolete and the new proposed model Morpho Sigma Series is the equal replacement. 

2. Provide a justification letter either from Bioscypt or Morpho. 

3. Justification letter from Maxxess is acceptable only for confirming the compatability of both manufacturer's proposed products with KAUST existing system.
