(740 ILCS 100/3)
(from Ch. 70, par. 303)
Amount of Contribution.
The pro rata share of each tortfeasor shall
be determined in accordance with his relative culpability. However, no
person shall be required to contribute to one seeking contribution an amount
greater than his pro rata share unless the obligation of one or more of
the joint tortfeasors is uncollectable. In that event, the remaining tortfeasors
shall share the unpaid portions of the uncollectable obligation in accordance
with their pro rata liability.
If equity requires, the collective liability of some as a group shall constitute
a single share.
