Leaves site to work around ten (5)
I believe the answer is:
Here is my best explanation:
'leaves' is the definition.
('exit' can be a synonym of 'leave')
'site to work around ten' is the wordplay.
'to work' is an anagram indicator.
'around' indicates putting letters inside.
'ten' becomes 'x' ('X' can be a synonym of 'ten').
'site' is an anagram of 'eits'.
'eits' enclosing 'x' is 'EXITS'.
(Other definitions for exits that I've seen before include "Ways out", "Goes out, leaves", "Withdraws", "Leaves the stage", "Departs", "Egresses" and "...goes out".)
