Notwithstanding any other provisions of this chapter:

(a)  No person serving without compensation as a volunteer, director, officer, or trustee of a nonprofit corporation, including a corporation qualified as a tax-exempt corporation under § 501(c) of the United States Internal Revenue Code, 26 U.S.C. § 501(c), or of an unincorporated nonprofit organization or an unincorporated public charitable institution qualified as a tax-exempt organization under § 501(c) of the United States Internal Revenue Code, is liable to any person based solely on his or her conduct in the execution of the office or duty unless the conduct of the director, officer, trustee, or volunteer regarding the person asserting the liability constituted malicious, willful, or wanton misconduct. As used in this section, “compensation” does not include a per diem or per meeting allowance, health insurance benefits, or reimbursement for out of pocket costs and expenses incurred in the service. Nothing in these provisions is construed to exempt a volunteer from liability based upon his or her ownership and/or operation of a motor vehicle.

(b)  Officers, directors, agents, servants, volunteers, and employees of a corporation are not liable for bodily injury to any person incurred while the person is practicing for, or participating in, any contest or exhibition of an athletic or sports nature sponsored by the corporation; provided, that the person has, or in the case of a minor, a parent or guardian of the minor has, signed a written waiver of liability of the corporation and acknowledgment of assumption of risk regarding the practicing for, or participating in, any contest or exhibition of an athletic or sports nature sponsored by the corporation.
