                    This statement is being filed by (i) Husic Capital
                    Management, a California limited partnership and registered
                    investment adviser ("IA"), (ii) Frank J. Husic and Co., a
                    California corporation ("Corporate G.P.") and (iii) Frank J.
                    Husic ("Shareholder") (collectively, the "Reporting
                    Persons"). Corporate G.P. controls IA by virtue of its
                    position as the sole general partner of IA. Shareholder
                    controls IA by virtue of Shareholder's position as the sole
                    shareholder of Corporate G.P.

                    IA's beneficial ownership of the Common Stock is direct as a
                    result of IA's discretionary authority to buy, sell, and
                    vote shares of such Common Stock for its investment advisory
                    clients. Corporate G.P.'s beneficial ownership of Common
                    Stock is indirect as a result of its control of IA.
                    Shareholder's beneficial ownership of Common Stock is
                    indirect as a result of Shareholder's stock ownership in
                    Corporate G.P. The beneficial ownership of the Corporate
                    G.P. and Shareholder is reported solely because Rules
                    13d-1(a) and (b) under the Securities Exchange Act of 1934,
                    as amended, require any person who is "directly or

                    Corporate G.P. and Shareholder are given on the basis of the
                    "indirect" beneficial ownership referred to in such Rule,
                    based on the direct beneficial ownership of Common Stock by
                    IA and the relationship of Corporate G.P. and Shareholder to
                    IA referred to above.

                    solely by the respective Reporting Person, and no Reporting
