Item 10.        Certification
        By signing below I certify that, to the best of my knowledge
and belief, the securities referred to above were acquired in
the ordinary course of business and were not acquired for
the purpose of and do not have the effect of changing or
influencing the control of the issuer of such securities and
were not acquired in connection with or as a participant
in any transaction having such purposes or effect.

        Connor, Clark & Lunn Investment Management Ltd. ("Company")
        is of the view that it and the investment companies and other
        accounts that it manages are not acting as a "group" for the
        purposes of section 13(d) under the Act and that it and such
        investment companies and accounts are not otherwise required
        to attribute to each other the "beneficial ownership" of securities
        "beneficially owned" under Rule 13D-3 promulgated under the
        1934 Act.  Therefore, it is of the view that the shares held
        by the Company and such investment companies and accounts should
         not be aggregated for purposes of section 13(d).

        After reasonable inquiry and to the best of my knowledge and
belief, I certify that the information set forth in this statement
is true, complete and correct.
