Item 6  Ownership of More than Five Percent on Behalf of Another
        Person

        (1) Price Associates does not serve as custodian of the
            assets of any of its clients; accordingly, in each
            instance only the client or the client's custodian or
            trustee bank has the right to receive dividends paid
            with respect to, and proceeds from the sale of, such
            securities.

            The ultimate power to direct the receipt of dividends
            paid with respect to, and the proceeds from the sale
            of, such securities, is vested in the individual and
            institutional clients which Price Associates serves as
            investment adviser.  Any and all discretionary
            authority which has been delegated to Price Associates
            may be revoked in whole or in part at any time.

            Except as may be indicated if this is a joint filing
            with one of the registered investment companies
            sponsored by Price Associates which it also serves as
            investment adviser ("T. Rowe Price Funds"), not more
            than 5% of the class of such securities is owned by any
            one client subject to the investment advice of Price
            Associates.

        (2) With respect to securities owned by any one of the T.
            Rowe Price Funds, only State Street Bank and Trust
            Company, as custodian for each of such Funds, has the
            right to receive dividends paid with respect to, and
            proceeds from the sale of, such securities.  No other
            person is known to have such right, except that the
            shareholders of each such Fund participate
            proportionately in any dividends and distributions so
            paid.

Item 10   Certification.

          By signing below I (we) certify that, to the best of my
          (our) 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

          issuer of such securities and were not acquired in
          connection with or as a participant in any transaction
          having such purpose or effect.  T. Rowe Price Associates,

          Schedule 13G shall not be construed as an admission that
          Price Associates is the beneficial owner of the
          securities referred to, which beneficial ownership is
          expressly denied.

                            Signature.
