     the Securities and that it will comply with the Securities Selling
     Prospectus Act (the "SSPA") of the Federal Republic of Germany (Wertpapier
     Verkaufsprospektgesetz). In particular, each Underwriter represents that it
     has undertaken not to engage in a public offering (offentliche Anbieten) in
     the Federal Republic of Germany with respect to any Securities otherwise
     than in accordance with the SSPA and any other act replacing or

          (g) it and each of its affiliates has not offered or sold, and it will
     not offer or sell, the Securities by means of any document to persons in
     Hong Kong other than persons whose ordinary business it is to buy or sell

     circumstances which do not constitute an offer to the public within the
     meaning of the Hong Kong Companies Ordinance (Chapter 32 of the Laws of
     Hong Kong), and unless permitted to do so under the securities laws of Hong
     Kong, no person has issued or had in its possession for the purposes of
     issue, and will not issue or have in its possession for the purpose of
     issue, any advertisement, document or invitation relating to the Securities
     other than with respect to the Securities to be disposed of to persons
     outside Hong Kong or only to persons whose business involves the
     acquisition, disposal or holding of securities, whether as principal or
     agent; and

          (h) it acknowledges that the Securities may not be offered, sold,
     transferred or delivered in or from The Netherlands as part of their
     initial distribution or at any time thereafter directly or indirectly,

          In addition to the legal opinions required by Sections 6(b) and (c) of
the Basic Provisions, the Underwriters shall have received an opinion of
Skadden, Arps, Slate, Meagher & Flom LLP, special U.S. tax counsel to the
Company, dated the Closing Date, to the effect that although the discussion set
forth in the Prospectus dated March 2, 2006 under the heading "United States
Federal Income Tax Considerations--Non-United States Holders" does not purport
to discuss all possible United States federal income tax consequences of the
purchase, ownership and disposition of the Securities to non-United States
holders of the Securities, such discussion constitutes, in all material
respects, a fair and accurate summary of the United States federal income tax
consequences of the purchase, ownership and disposition of the Securities to
non-United States holders of the Securities.

          Michael S. Zuckert, Esq., General Counsel, Finance and Capital Markets
of the Company, is counsel to the Company. Skadden, Arps, Slate, Meagher & Flom
LLP is special U.S. tax counsel to the Company. Cleary Gottlieb Steen & Hamilton
LLP is counsel to the Underwriters.
