ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

On September 6, 2001, we sold the operating assets of a majority of our antibody
collection business and our testing laboratory (collectively the "Transferred
Antibody Collection Business") to CSL Limited ("CSL") for $152 million in cash,
subject to closing adjustments (as of September 6, 2001, these closing
adjustments resulted in the receipt of an additional $1 million in cash by us).
The assets sold were certain real estate, leasehold interests, fixtures,
furniture, tools, machinery and equipment, other fixed assets, plasma
inventories and related supplies, contracts, agreements, arrangements and/or
commitments, licenses and permits, business and financial records, intellectual
property and goodwill related to the operation of 47 of our current 56 antibody
collection centers and our testing laboratory. The purchase price we received
was the result of arm's-length bargaining between CSL and us. There is no
material relationship between CSL and us or, to our knowledge, between CSL and
any of our affiliates, any of our Directors or officers or any associate of any
such Director or officer.

ITEM 7(b) CONDENSED CONSOLIDATED PRO FORMA FINANCIAL INFORMATION INTRODUCTION

On September 6, 2001, we completed the sale of the operating assets of 47 of our
antibody collection centers and the majority of our testing laboratory
(collectively the "Transferred Antibody Collection Business") to CSL Limited
("CSL"). Total cash proceeds from the sale were $153 million, after closing
adjustments as of the time of sale pursuant to the Asset Purchase Agreement,
dated June 25, 2001, as amended. Further closing adjustments will be made as
provided for in the agreement.

We applied $18 million of the proceeds to pay back all of our short-term debt as
of the closing date which comprised a revolving credit facility and a term loan.
The remaining proceeds will be used for working capital and other corporate
purposes, and may be used to position us to accelerate the development of our
research and development pipeline and to acquire or in-license additional
biopharmaceutical products.

For purposes of this document, the unaudited condensed consolidated pro forma
balance sheet of Nabi set forth below is used to show the effects of the sale of
the Transferred Antibody Collection Business as if it occurred on June 30, 2001
based on certain estimates and assumptions. The unaudited condensed consolidated
pro forma balance sheet includes pro forma adjustments to give effect to the
disposition of assets and the use of proceeds as though they had occurred as of
June 30, 2001. We used June 30, 2001 because it marks the end of the latest
fiscal period for which financial information is publicly available.

The accompanying unaudited condensed consolidated pro forma income statements
for the six months ended June 30, 2001 and the year ended December 30, 2000
assume that the assets were disposed of as of January 1, 2000 and eliminates the
estimated historical results of operations of the Transferred Antibody
Collection Business from the historical results of operations of Nabi for the
six months ended June 30, 2001 and the year ended December 30, 2000, and the
interest expense related to the short-term debt that was repaid with the
proceeds.

The accompanying pro forma information should be read in conjunction with our
annual report on Form 10-K for the fiscal year ended December 30, 2000, the
quarterly report on Form 10-Q for the period ended June 30, 2001 and the current
report on Form 8-K filed on July 10, 2001. The pro forma information is not
necessarily indicative of the results that would actually have occurred had this
transaction been consummated on the dates or for the periods indicated or that
may occur in the future. For example, lower antibody product margins in 2000
reflect higher costs of production including higher donor fees and increased
cost of regulatory compliance as discussed in our 2000 Form 10-K. Further, had
the transaction occurred on January 1, 1999, the Pro Forma Sales less Costs of
Products Sold would have been $12 million for the year ended December 31, 1999
as compared to Pro Forma Sales less Pro Forma Costs of Products Sold of ($4)
million for the year ended December 30, 2000.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

PRO FORMA ADJUSTMENTS: The following adjustments have been made to the condensed
consolidated pro forma balance sheet of Nabi at June 30, 2001 and to the
condensed consolidated pro forma income statements for the six months ended June
30, 2001 and the year ended December 30, 2000:

A.   Reflects total proceeds of $153 million received by Nabi from CSL.

B.   Reflects repayment of short-term debt that comprised a revolving credit
     facility and a term loan. For the purposes of this unaudited pro forma
     condensed consolidated balance sheet, it has been assumed that all
     short-term debt is repaid on June 30, 2001. At June 30, 2001, short-term
     debt was $24,478 compared to $17,608 as of September 6, 2001, the date of
     completing the transaction.

C.   Reflects the values of plasma inventory sold associated with the
     transaction.

D.   Relates to estimated amounts receivable for reimbursement of transferred
     assets including inventory.

E.   Reflects the carrying value of fixed assets sold.

F.   Reflects the disposition of goodwill and other intangibles related to the
     antibody collection centers.

G.   Relates to accrued transaction costs and an estimated tax liability

H.   Reflects estimated gain resulting from the sale of the Transferred Antibody
     Collection Business and other assets and liabilities incurred or relieved
     as a result of the sale. The net estimated gain on sale as of June 30, 2001
     is recorded as an increase to stockholder's equity. The final pre-tax gain
     amount will be determined based on the excess of proceeds received over the
     actual carrying value of the Transferred Antibody Collection Business's net
     assets as of September 6, 2001 less direct costs associated with the sale.

sale as of September 6, 2001:
