                               POWER OF ATTORNEY

        The undersigned, as a Section 16 reporting person of ESS, Inc. (the

        1.  complete and execute Forms 3, 4 and 5 and other forms and all
            amendments thereto as such attorney-in-fact shall in his discretion
            determine to be required or advisable pursuant to Section 16 of the
            Securities Exchange Act of 1934 (as amended) and the rules and
            regulations promulgated thereunder, or any successor laws and
            regulations, as a consequence of the undersigned's ownership,
            acquisition or disposition of securities of the Company; and

        2.  do all acts necessary in order to file such forms with the SEC, any
