         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 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.
