Item 6. Ownership of More than 5 Percent on Behalf of Another Person.

        Neuberger Berman, LLC is deemed to be a beneficial owner for purpose of
        Rule 13(d) since it has shared power to make decisions whether to retain
        or dispose, and in some cases the sole power to vote, the securities of
        many unrelated clients. Neuberger Berman, LLC does not, however, have
        any economic interest in the securities of those clients. The clients
        are the actual owners of the securities and have the sole right to
        receive and the power to direct the receipt of dividends from or
        proceeds from the sale of such securities.

        With regard to the shares set forth under item 4. (c) (II), Neuberger
        Berman, LLC and Neuberger Berman Management LLC are deemed to be
        beneficial owners for purposes of Rule 13 (d) since they both have
        shared power to make decisions whether to retain or dispose and vote the
        securities. Neuberger Berman, LLC and Neuberger Berman Management LLC
        serve as a sub-adviser and investment manager, respectively, of
        Neuberger Berman's various Mutual Funds which hold such shares in the
        ordinary course of their business and not with the purpose nor with the
        effect of changing or influencing the control of the issuer. The
        holdings of Lehman Brothers Asset Management LLC and Lehman Brothers
        Asset Management Inc, affiliates of Neuberger Berman LLC, are also
        aggregated to comprise the holdings referenced herein.

        No other Neuberger Berman, LLC advisory client has an interest of more
        than 5% of the issuer.

        It should be further noted that the share calculation under item 4. (c)
        (IV) is derived from a total combination of the shares set forth under
        Item 4. (c) (I and II). The remaining balance of shares, if any, are for
        the individual client accounts over which Neuberger Berman, LLC has
        shared power to dispose but not vote shares.


Item 7. Identification and Classification of the Subsidiary Which Acquired the
        Security Being Reported on by the Parent Holding Company or Control
        Person.

        Neuberger Berman Inc. makes this filing pursuant to the Rule 13d-1 (b)
        (ii) (G) since it owns 100% of both Neuberger Berman, LLC and Neuberger
        Berman Management LLC and does not own over 1% of the issuer, and is
        affiliated with Lehman Brothers Asset Management LLC & Lehman Brothers
