         In addition to the legal opinions required by Sections 5(c) and 5(d) 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 Supplement under the heading "United States Federal
Income Tax Considerations For 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.

         John R. Dye, Esq., Associate General Counsel of the Company, is counsel
to the Company. Skadden, Arps, Slate, Meagher & Flom LLP is special tax counsel
to the Company. Dewey Ballantine LLP is counsel to the Underwriters.
