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 7    Identification and Classification of the Subsidiary Which
          Acquired the Security Being Reported on By the Parent
          Holding Company.

          Not Applicable.

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
    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 purpose or effect.  T. Rowe Price
    Associates, Inc. hereby declares and affirms that the
    filing of Schedule 13G shall not be construed as an
