Supplied on condition (8)
I believe the answer is:
provided
I believe this clue is a double definition.
'supplied' is the first definition.
('provide' can be a synonym of 'supply')
'on condition' is the second definition.

(Other definitions for provided that I've seen before include "... on understanding that" , "If - supplied" , "in the event" , "furnished" , "Given" .)
