        This Prospectus Supplement (the "Supplement") relates to the resale by
Kapor Family Foundation of up to $100,000 aggregate principal amount of 6 1/2%
Convertible Subordinated Notes due 2003 (the "Notes") of NABI, a Delaware

NABI's Registration Statement on Form S-3 (No. 333-2253) (the "Registration
Statement"). This Supplement should be read in conjunction with the Prospectus
dated May 3, 1996, as supplemented to date (the "Prospectus"), to be delivered
with this Supplement. All capitalized terms used but not defined in this
Supplement shall have the meanings given them in the Prospectus.

        Based on information provided to the Company, the aggregate principal
amount of the Notes that are currently beneficially owned by Kapor Family
Foundation is $100,000, of which all may be sold at this time pursuant to the
Prospectus as supplemented hereby. Additional information concerning the
Selling Securityholders (including Kapor Family Foundation) may be set forth
from time to time in additional supplements to the Prospectus. The total
outstanding aggregate principal amount of the Notes is $80,500,000.

        The closing price of the Company's Common Stock as reported on The
Nasdaq National Market on March 5, 1997 was $10.125 per share.

incurrence of additional indebtedness or other liabilities by the Company.
