Question on patches for 11i Minimum Base Line Patches for Extended Support

Hi,
Apps 11.5.10.2


We upgraded our 11.5.9 Instance to 11.5.10.2 in Aug-2010. At that time whatever the minimum baseline patches required we applied in our system.
Now we found that Oracle Support change extended support time line to 31-Nov-2013 and Sutain Support for Dec-2014.

currently our system is working find without any issue, still
do we need to apply all patches mention in •Patch Requirements for Extended Support of Oracle E-Business Suite Release 11.5.10 (Note 883202.1)?

what will happen if we don't applied patches?
What is the deadline for applying missing patches for Extended Support of 11i?


--We found that most of all our issue will resolved by Metaink notes.
