(2) The liability of an employer to another person who may be liable for or who has paid damages on account of an injury or occupational disease or death arising out of and in the course of employment of an employee of the employer and caused by the breach of any duty or obligation owed by the employer to such other person shall be limited to the amount of compensation for which the employer is liable under this law on account of such injury, disease, or death, unless such other person and the employer agree to share liability in a different manner.
(3) The exemption from liability given an employer by this section shall also extend to the employer’s surety and to all officers, agents, servants and employees of the employer or surety, provided that such exemptions from liability shall not apply in any case where the injury or death is proximately caused by the willful or unprovoked physical aggression of the employer, its officers, agents, servants or employees, which physical aggression must include clear and convincing evidence the employer, its officers, agents, servants, or employees either specifically intended to harm the employee or engaged in conduct knowing that injury or death to the employee was substantially likely to occur. The loss of such exemption applies only to the aggressor and shall not be imputable to the employer unless provoked or authorized by the employer or the employer was a party thereto.
