Contract providing prize money (5)
I believe the answer is:
purse
I believe 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' acts as a 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" .)
