    This Prospectus Supplement (the "Supplement") relates to the resale by
Raymond James & Associates, Inc. ("Raymond James") of up to $153,000 aggregate
principal amount of 6 1/2% Convertible Subordinated Notes due 2003 (the "Notes")
of NABI, a Delaware corporation (the "Company"), orginally issued in private
placements consummated on February 7 and March 6, 1996 (the "Debt Offering"),
pursuant to 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 Raymond James is $500,000,
of which $153,000 may be sold at this time pursuant to the Prospectus as
supplemented hereby. Raymond James was an initial purchaser of the Notes in the 
Debt Offering and also was the managing underwriter in the Company's October 
1994 public offering of 4,200,000 shares of Common Stock. In connection with 
both such offerings, Raymond James received customary compensation for its 
services. Additional information concerning the Selling Securityholders 
(including Raymond James) 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 August 20, 1996 was $8.625 per share.

    The Notes will be subordinated to all existing and future Senior 
Indebtedness of the Company. At June 30, 1996, Senior Indebtedness was 
approximately $6,300,000. The Indenture contains no limitations on the 
incurrence of additional indebtedness or other liabilities by the Company.
    
    The Notes are neither listed on a national securities exchange nor quoted on
an automated quotation system. However, the Notes are eligible for trading in
the Private Offerings, Resales and Trading through Automated Linkages ("PORTAL")
Market. Notes sold pursuant to the Registration Statement will no longer be
eligible for trading in the PORTAL Market.
