SUPPLEMENTAL DISCUSSION OF CERTAIN UNITED STATES
FEDERAL INCOME TAX CONSIDERATIONS


	The following discussion reflects certain changes in laws and 
regulations affecting United States federal income tax matters.  It 
supplements and, in the cases indicated below, supersedes portions of the 
discussion set forth in the accompanying Prospectus under the caption 
"Certain United States Federal Income Tax Considerations."  This discussion 
should be read in conjunction with, and is qualified in its entirety by 
reference to, the discussion appearing in the accompanying Prospectus 
Supplement under the caption "Certain United States Federal Income Tax 
Considerations."  Capitalized terms used in this discussion and not defined 
in this Pricing Supplement have the respective meanings set forth in the 
accompanying Prospectus Supplement.

	Definition of U.S. Person.  As the result of certain changes effected by 
the Taxpayer Relief Act of 1997, the following definition of "U.S. Holder" 
supersedes and replaces the definition of that term appearing in the 
accompanying Prospectus Supplement.  The term "U.S. Holder" means a 
beneficial owner of a Note that is for United States federal income tax 
purposes (i)a citizen or resident of the United States, (ii) a corporation, 
partnership or other entity created or organized in or under the laws of the 
United States or of any political subdivision thereof, (other than a 
partnership that is not treated as a United States person under any 
applicable Treasury regulations), (iii) an estate whose income is subject to 
United States federal income tax regardless of its source, (iv) a trust if a 
court within the United States is able to exercise primary supervision over 
the administration of the trust and one or more United States fiduciaries 
have the authority to control all substantial decisions of the trust.  
Notwithstanding the preceding sentence, to the extent provided in Treasury 
regulations, certain trusts in existence on August 20, 1996, and treated as 
United States persons under the United States Internal Revenue Code of 1986, 
as amended (the "Code"), and applicable Treasury regulations thereunder prior 
to such date, that elect to continue to be treated as United States persons 
under the Code or applicable Treasury regulations thereunder also will be 
U.S. Holders.

	Variable Notes.  The following discussion supersedes, to the extent 
inconsistent therewith, the discussion of "qualified floating rates" 
appearing under the caption "Certain United States Federal Income Tax 
Considerations -- U.S. Holders --Original Issue Discount" in the accompanying 
Prospectus Supplement.  Final Treasury regulations (the "Final Regulations") 
promulgated on June 11, 1996 changed several of the rules pursuant to which 
Floating Rate Notes and Indexed Notes ("Variable Notes") would be classified 
as "variable rate debt instruments."  Under the Final Regulations, a variable 
rate equal to the product of a qualified floating rate and a fixed multiple 
that is greater than 0.65 but not more than 1.35 will constitute a qualified 
floating rate.  A variable rate equal to the product of a qualified floating 
rate and a fixed multiple that is greater than 0.65 but not more than 1.35, 
increased or decreased by a fixed rate, will also constitute a qualified 
floating rate.




PAGE 3

	The Final Regulations also defined an "objective rate" as a rate that is 
not itself a qualified floating rate but which is determined using a single 
fixed formula and that is based on objective financial or economic 
information.  A rate will not qualify as an objective rate if it is based on 
information that is within the control of the issuer (or a related party) or 
that is unique to the circumstances of the issuer (or a related party), such 
as dividends, profits, or the value of the issuer's stock (although a rate 
does not fail to be an objective rate merely because it is based on the 
credit quality of the issuer).

	If a Variable Note qualifies as a "variable rate debt instrument" under 
the Final Regulations and if the interest on such Note is unconditionally 
payable in cash or property (other than debt instruments of the issuer) at 
least annually, then all stated interest on the Variable Note will constitute 
qualified stated interest and will be taxed accordingly.  The amount of 
qualified stated interest and the amount of original issue discount, if any, 
that accrues during an accrual period on such a Variable Note is determined 
under the rules applicable to fixed rate debt instruments by assuming that 
the variable rate is a fixed rate equal to (i) in the case of a qualified 
floating rate or qualified inverse floating rate, the value, as of the issue 
date, of the qualified floating rate or qualified inverse floating rate, or 
(ii) in the case of an objective rate (other than a qualified inverse 
floating rate), a fixed rate that reflects the yield that is reasonably 
expected for the Variable Note.  The qualified stated interest allocable to 
an accrual period is increased (or decreased) if the interest actually paid 
during an accrual period exceeds (or is less than) the interest assumed to be 
paid during the accrual period pursuant to the foregoing rules.

	If a Variable Note does not qualify as a "variable rate debt instrument" 
under the Final Regulations, then the Variable Note would be treated as a 
contingent payment debt obligation.  In general, the Final Regulations would 
cause the timing and character of income, gain or loss reported on a 
contingent payment debt instrument to substantially differ from the timing 
and character of income, gain or loss reported on a contingent payment debt 
instrument under general principles of current United States Federal income 
tax law.  Specifically, the Final Regulations generally require a U.S. Holder 
of such an instrument to include future contingent and noncontingent interest 
payments in income as such interest accrues based upon a projected payment 
schedule.  In general, under the Final Regulations, any gain recognized by a 
U.S. Holder on the sale, exchange, or retirement of a contingent payment debt 
instrument will be treated as ordinary income and all or a portion of any 
loss realized could be treated as ordinary loss as opposed to capital loss 
(depending upon the circumstances).  The Final Regulations apply to 
contingent payment debt instruments issued on or after August 13, 1996.

	Market Discount and Premium.  A U.S. Holder may elect to include market 
discount in income (or amortize premium where applicable) currently as it 
accrues (on either a ratable or semiannual compounding basis).  Such an 
election will apply to all debt instruments acquired by the U.S. Holder on or 
after the first day of the first taxable year to which such election applies 
and may be revoked only with the consent of the Internal Revenue Service.

	Disposition of a Note.  The Taxpayer Relief Act of 1997 reduces the 
maximum rates on long-term capital gains recognized on capital assets held by 



PAGE 4


individual taxpayers for more than eighteen months as of the date of 
disposition (and would further reduce the maximum rates on such gains in the 
year 2001 and thereafter for certain individual taxpayers who meet specified 
conditions).  Prospective investors should consult their own tax advisors 
concerning these tax law changes.

	Backup Withholding.  Final withholding regulations issued on October 6, 
1997 changed the withholding rules for payments to foreign persons effective 
for payments made after December 31, 1998.  Prospective investors should 
consult their own tax advisors concerning these tax law changes.
