SQL Diagnostic Manager Pro and Compliance Manager

Hi I am interested in the two product below

SQL Diagnostic Manager Pro - Single License : per instance (Regular Price $2,695.00)
SQL Compliance Manager - Single License : per instance (Reg. Price $3,795.00)

Are these pricing for corporate use?

Also what is the maintenance or license fee per year?

Single license mean only one user can connect at one time?

what is the price for a 5 x license use for each?
