As additional compensation to a state employee, a state agency may reimburse the employee for or pay a travel expense the employee incurs while attending the funeral of an individual who was a state employee, a board member, or a member of the legislature if:
(1) the agency determines that the employee's attendance at the funeral is appropriate under the circumstances; and
(2) the expense is paid or reimbursed only to the extent it could have been paid or reimbursed had it been incurred while conducting official state business.
