What is the EOS and EOL dates for ArcSight Express 4.0?

What is the end of support and end of life date on ArcSight Express 4.0? Client has a AE7551 hardware box.

The ESM support matrix shows AE4.0, EOSL (end-of-support and life), past on 12/31/2016 but I'm hearing from others that this was only the End of Sale not end of Support.  Can anyone clarify?
