(e) If any defendant answers or otherwise appears personally and the court finds that he is an unknown or missing owner of a severed mineral interest, the court shall enter an order determining the interest of such defendant and he shall be dismissed from the action. The appearance by a guardian ad litem appointed pursuant to subsection 5(d) (2) or 5(d) (3) of this Section shall not be deemed a personal appearance within the meaning of this subsection (e).

The court may designate the place and manner of holding the sale and may determine whether said sale shall be private or public. The court, in its discretion, may require the trustee to give a bond which shall be approved by the court. The court shall determine a reasonable fee to be paid to the trustee and said fee, together with the reasonable attorneys' fees and costs of the proceeding incurred by such trustee, shall be paid by the purchaser of the mineral lease.
