which they will consult with each other as to the election of a mutually
acceptable Board of Directors of the Company.

                Except as discussed above, neither Mr. Cumming nor Mr. Steinberg
has any present plans or intentions that would result in or relate to any of the
transactions described in subparagraphs (a) through (j) of Item 4 of Schedule
13D.

                (c) On September 24, 2004, Mr. Cumming sold in a private
