United States Taxation

          In the opinion of Arnold & Porter, special tax counsel to the Corporation, the following paragraphs, when read in conjunction with the discussion under "United States Taxation" in the Offering Circular, correctly describe 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

Tax rates on capital gain for individual Owners vary depending on each Owner's income and holding period for the Note.  Owners who are individuals should contact their own tax advisors for more information or for the capital gains tax rate applicable to a specific Note.
 

Final Regulations Relating to Withholding and Information Reporting

The Offering Circular describes proposed regulations issued by the IRS relating to withholding, backup withholding and information reporting with respect to payments made to Non-U.S. Persons. In October 1997, the IRS finalized those regulations, and in March 1998 the IRS announced a delay in the effective date of the final regulations. The final regulations generally are effective for payments made after December 31, 1999. However, withholding certificates that are valid under the present rules and that are held by a Withholding Agent on December 31, 1999, remain valid until the earlier of December 31, 2000 or the expiration date of the certificate under the present rules (unless otherwise invalidated due to changes in the circumstances of the person whose name is on the certificate).

When effective, the new regulations will streamline and, in some cases, alter the types of statements and information that must be furnished to a Withholding Agent to claim a reduced rate of withholding. While various IRS forms (such as IRS Forms 1001 and 4224) currently are used to claim exemption from withholding or a reduced withholding rate, the preamble to the regulations states that the IRS intends most certifications to be made on revised Form W-8. The regulations also clarify the duties of Withholding Agents and modify the rules concerning withholding on payments made to Non-U.S. Persons through foreign intermediaries. With some exceptions, the new regulations treat a payment to a foreign partnership as a payment directly to the partners.
