(b) For purposes of Subsection (a), a person is not materially involved in a contract or transaction that is the subject of a claim or challenge and does not have a material financial interest in the outcome of a contract or transaction or the disposition of a claim or challenge solely because:

(A) interested in the contract or transaction; or

(B) alleged to have engaged in the conduct that is the subject of the claim or challenge;

(2) the person receives normal fees or customary compensation, reimbursement for expenses, or benefits as a governing person of the entity;

(A) the person is named as a defendant in the derivative proceeding regarding the matter or as a person who engaged in the alleged conduct; or

(B) the person, acting as a governing person, approved, voted for, or acquiesced in the act being challenged if the act did not result in a material personal or financial benefit to the person and the challenging party fails to allege particular facts that, if true, raise a significant prospect that the governing person would be held liable to the entity or its owners or members as a result of the conduct.
