st: identifying age-matched controls in a cohort study

Dear all,
I am analysing data from a large cohort study in which some individuals become exposed during the 5 year observation period. For each exposed individual, how can I identify the nearest age-matched, unexposed individual that is alive on the date that the exposed become exposed?
Many thanks,
Menno
