United States Taxation

          In the opinion of Arnold & Porter, special tax counsel to the Corporation, the following paragraph, when read in conjunction with the discussion under "United States Taxation" in the Offering Circular, correctly describes the principal aspects of the current United States federal tax treatment of investors who purchase the Notes described in the Offering Circular. The discussion does not purport to deal with all tax consequences applicable to all categories of investors, some of which may be subject to special rules.

Recent Tax Legislation

          The Taxpayer Relief Act of 1997 modified the federal income taxation of capital gains. The maximum tax rate on capital gains received by individuals from the sale or disposition of investments (other than collectibles) held for more than 18 months is 20 percent. If an individual holds an investment for more than one year, but not for more than 18 months, the maximum rate is 28 percent. Finally, the top capital gains tax rate for individuals will drop to 18 percent for assets purchased after January 1, 2000, and held for more than five years. Investors should consult their own tax advisors for more information or for the capital gains rate applicable to a specific Note they own.
