(a) the percentage share of liability for each person as determined by the allocator;

(10) A person who did not participate in the allocation but who was assigned a share of liability may sign the stipulated agreement prepared according to subsection (8).

(12) Any liable person who signs the stipulated agreement and fails to comply with the terms of the stipulated agreement shall pay, in addition to the person's share of remedial action costs, a penalty of two times the amount of the person's allocated share of liability. Any funds received must be applied to the facility's orphan share and any funds in excess of the facility's orphan share amount must be deposited in the orphan share fund established under 75-10-743.

(13) If a liable person becomes bankrupt or defunct after the stipulated agreement is signed and before remedial actions are complete at the facility, that person's share of liability becomes an orphan share.
