If a partner of a special county employee or of a former county employee is also a member of another partnership in which the special or former employee has no interest, activities of the latter partnership in which the special or former employee takes no part shall not thereby be subject to clause (c) or (d).
This section shall not prevent a present or former special county employee from aiding or assisting another person for compensation in the performance of work under a contract with or for the benefit of the county; provided, that the head of the special county employee's department or agency has certified in writing that the interest of the county requires such aid or assistance and the certification has been filed with the state ethics commission. The certification shall be open to public inspection.
