(2) Subject to Subsection (3), the following claims are subordinate to a claim or interest that is senior or equal in priority to a claim or interest represented by a security or other equity interest in the assignor or an affiliate of the assignor:
(a) a claim arising from rescission of a purchase or sale of the security or other equity interest;
(b) a claim for damages arising from the purchase or sale of the security or other equity interest; and
(c) a claim for reimbursement or contribution allowed on account of the rescission or damage claim.
(3) If the security is common stock or another common equity interest, a claim subject to subordination under Subsection (2) has the same priority as common stock or another common equity interest.
