          (c)  The Escrow Agent may consult with, and obtain advice from, legal
     counsel in the event of any dispute or question as to the construction of
     any of the provisions hereof or its duties hereunder, and it shall incur no
     liability and shall be fully protected in acting in good faith in
     accordance with the opinion and instructions of such counsel.

     8.   The Escrow Agent shall be entitled to reasonable compensation for its
services hereunder, including reimbursement for reasonable counsel fees and
other out-of-pocket expenses incurred by the Escrow Agent in the performance of
its duties hereunder.  The compensation so payable shall be paid by MicroTel
