Contract providing prize money (5)
I believe the answer is:
purse
This clue is a double definition.
'contract' is the first definition.
(as in pursing one's lips)
'prize money' is the second definition.
(I've seen this in another clue)
'providing' is the link.
(Other definitions for purse that I've seen before include "Handbag or money prize" , "Woman's wallet" , "Small pouch for carrying money, mostly by women" , "Money - contract" , "Prize in sporting contest" .)
