     is a pension trust formed pursuant to the laws of the of the State of New
     York for the benefit of certain employee benefit plans of General Motors
     Corporation ("GM"), its subsidiaries and unrelated employers. These shares
     may be deemed to be owned beneficially by GMIMCo, a wholly-owned subsidiary
     of GM. GMIMCo is registered as an investment adviser under the Investment
     Advisers Act of 1940, as amended. GMIMCo's principal business is providing
     investment advice and investment management services with respect to the
     assets of certain employee benefit plans of GM, its subsidiaries and
     unrelated employers, and with respect to the assets of certain direct and
     indirect subsidiaries of GM and associated entities. GMIMCo is serving as
     investment manager with respect to these shares and in that capacity it has
     the sole power to direct JPMorgan Chase Bank, as Trustee for the GMAM Group
     Pension Trust II, and General Motors Trust Bank, National Association, as
     Trustee for the GMAM Investment Funds Trust (together, the "Trustees"), as
     to the voting and disposition of these shares. Because of the Trustees'
     limited role, beneficial ownership of the shares by the Trustees is
     disclaimed.

{2}  Each of the GMAM Investment Funds Trust and the GMAM Group Pension Trust II
     invests in a variety of investment media, including publicly traded and
     privately placed securities. Such investments could include Common Stock
     and/or other securities of the Issuer in addition to those referred to in
     this Statement ("Additional Securities"). The investment and voting
     decisions regarding any Additional Securities which might be owned by the
     GMAM Investment Funds Trust or the GMAM Group Pension Trust II are made by
     the Trustees or unrelated investment managers who, in so acting, act
     independently of the Reporting Persons (although the appointment of the
     Trustees and the investment managers is subject to the authorization of
     GMIMCo). The Reporting Persons do not have or share voting power or
     investment power over any Additional Securities which might be held by the
     GMAM Investment Funds Trust or the GMAM Group Pension Trust II. No
     information regarding any such holdings by the GMAM Investment Funds Trust
     or the GMAM Group Pension Trust II is contained in this Statement.
