        the date of this report, the reporting person(s) has (have)
        ceased to be the beneficial owner of more than five percent of

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.

        Acquired the Security Being Reported on By the Parent Holding
        Company.

Item 9    Notice of Dissolution of Group.

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 admission that Price Associates is the
    beneficial owner of the securities referred to, which
    beneficial ownership is expressly denied.

                              Signature.

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