THREE MONTHS ENDED JUNE 30, 1999 AND 1998

SALES. Sales for the second quarter of 1999 increased by $1 million to $62.2
million, compared to $61.2 million for the second quarter of 1998.
Pharmaceutical sales increased 17% from the 1998 second quarter. This increase
reflected increased sales of existing products, WinRho SDF(TM) and Autoplex(R)T,
and sales of ALOPRIM(TM), a new pharmaceutical product that Nabi in-licensed and
launched at the end of the second quarter in 1999. Total antibody sales
decreased by $1.6 million from the 1998 second quarter. Consistent with the
Company's objectives for 1999 to shift revenues toward specialty products and
improve antibody margins, specialty antibody product sales increased almost 10%,
reflecting higher volumes for most products, including tetanus, anti-CMV and
rabies products, which more than offset the cessation of anti-RSV product sales.
Non-specific antibody sales decreased 9% from the comparable 1998 period due to
lower production, reflecting in part the effect of the sale of six antibody
collection centers in April 1999.

GROSS PROFIT MARGIN. Gross profit and related margin for the second quarter of
1999 was $ 19.5 million, a record level of 31.4% of sales, compared to $17.6
million, or 28.8% of sales, in the second quarter of 1998. The gains in gross
profit and related margin reflects the Company's success in improving sales mix
toward higher-margin specialty antibody products and pharmaceutical products. In
addition, the 1999 results reflect management's efforts to manage costs and
optimize production in the antibody business.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSE. Selling, general and administrative
expense was $8.5 million, or 13.7% of sales, for the second quarter of 1999
compared to $8.2 million, or 13.4% of sales, in the second quarter of 1998. This
increase resulted from higher sales and marketing expenses associated with
increasing pharmaceutical product sales, the launch of Nabi-HB(TM), and
increased system costs related to Year 2000 readiness. This increase was
partially offset by a reduction in other general and administrative expenses for
the 1999 quarter.

RESEARCH AND DEVELOPMENT EXPENSE. Research and development expense was $3.9
million, or 6.2% of sales, for the second quarter of 1999 compared to $5.6
million, or 9.2% of sales, in the second quarter of 1998. Nabi incurred
significant expenditures during 1998 related to the advancement of clinical
trials for Nabi-HB(TM) which was approved by the FDA in March 1999. In 1999,
Nabi has reduced pre-clinical product development activities and has focused its
ongoing research and development efforts to support currently marketed products
and those in later stages of development. At the same time, the Company is
actively seeking corporate and government partners to fund the significant cost
of further development for the products in its research and development
pipeline.

ROYALTY EXPENSE. Royalty expense was $3.9 million, or 6.3% of sales, in the
second quarter of 1999, compared to $3.1 million, or 5.0% of sales, in the
second quarter of 1998. The increase is attributable to higher sales of
pharmaceutical products and Nabi-HB(TM) royalties payable to the New York Blood
Center based on the reformulated product.

INTEREST EXPENSE. Interest expense for the second quarter of 1999 was $1
million, or 1.6% of sales, compared to $1.4 million, or 2.2% of sales, in the
second quarter of 1998. The decrease is primarily






                                       10
   11

attributable to higher amounts of interest capitalized during the 1999 second
quarter. Capitalized interest relating primarily to construction of Nabi's
biopharmaceutical manufacturing facility in Boca Raton, Florida was
approximately $1.2 million in the 1999 second quarter as compared to $0.8
million during the 1998 period.

OTHER FACTORS. Provision for income taxes was $0.8 million, recorded at an
effective rate of 41.8%, in the second quarter of 1999 compared to a $0.6
million benefit, or an effective rate of 52%, in the second quarter of 1998. The
41.8% effective tax rate for the second quarter of 1999 differs from the
statutory rate of 35% primarily due to foreign income, non-deductible goodwill
and state income taxes.




SIX MONTHS ENDED JUNE 30, 1999 AND 1998

SALES. Sales for the first half of 1999 increased by $0.4 million to $120.2
million compared to $119.8 million for the first half of 1998. The increase
resulted primarily from a 15% increase in sales of specialty antibody products,
reflecting higher volumes for most products, including hepatitis B, tetanus,
anti-CMV, rabies and anti-D products, partially offset by the cessation of
anti-RSV product sales. Non-specific antibody sales decreased by $4.7 million
due to lower production in 1999. This is in part due to the impact of the sale
of six centers in April 1999 and, the Company believes, low unemployment levels
which has made it difficult to attract potential donors. Pharmaceutical product
sales increased by $1.5 million primarily due to increased sales of Autoplex(R)T
and sales of ALOPRIM(TM), a new pharmaceutical product that Nabi in-licensed and
launched at the end of the second quarter in 1999.

GROSS PROFIT MARGIN. Gross profit and related margin for the first half of 1999
was $32.3 million, or 26.9% of sales, compared to $31.7 million, or 26.4% of
sales, in the first half of 1998. The $0.7 million increase in gross profit and
related margin resulted from an improved sales mix of higher-margin specialty
antibody products and pharmaceutical products. In addition, the 1999 results
reflect management's efforts to manage costs and optimize production in the
antibody business.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSE. Selling, general and administrative
expense was $15 million, or 12.5% of sales, for the first half of 1999 compared
to $16.2 million, or 13.5% of sales, in the first half of 1998. This $1.2
million decrease reflects the impact of higher general and administrative
expense in 1998 due to costs associated with reorganizational measures initiated
in the first half of 1998. This reduction was partially offset by increased
sales and marketing expenses in 1999 associated with increased pharmaceutical
product sales, the launch of Nabi-HB(TM), and increased system costs related to
Year 2000 readiness.

RESEARCH AND DEVELOPMENT EXPENSE. Research and development expense was $7.1
million, or 5.9% of sales, for the first half of 1999, compared to $10.4
million, or 8.7% of sales, in the first half of 1998. Nabi incurred significant
expenditures during 1998 related to the advancement of clinical trials for
Nabi-HB(TM) which was approved by the FDA in March 1999. In 1999, Nabi has
reduced pre-clinical product development activities and has focused its ongoing
research and development efforts to support currently marketed products and
those in later stages of development. At the same time, the Company is actively
seeking corporate and government partners to fund the significant cost of
further development for the products in its research and development pipeline.

ROYALTY EXPENSE. Royalty expense for the first half of 1999 was $6.1 million, or
5.1% of sales, compared to $5.9 million, or 4.9% of sales, in the first half of
1998. The increase is attributable to higher sales of pharmaceutical products
and Nabi-HB(TM) royalties payable to the New York Blood Center based on the
reformulated product.

INTEREST EXPENSE. Interest expense for the first half of 1999 was $2.3 million,
or 1.9% of sales, compared to $3.2 million, or 2.6% of sales, in the first half
of 1998. The decrease is primarily attributable to higher





                                       11
   12

amounts of interest capitalized during the first half of 1999. Capitalized
interest relating primarily to construction of Nabi's biopharmaceutical
manufacturing facility in Boca Raton, Florida was approximately $2.3 million
during the first six months of 1999 as compared to $1.6 million during the 1998
period.

OTHER FACTORS. Provision for income taxes was $0.4 million or an effective rate
of 41%, in the first half of 1999 compared to a $2.6 million benefit, or an
effective rate of 52%, in the first half of 1998. The 41% effective tax rate for
1999 differs from the statutory rate of 35% primarily due to foreign income,
non-deductible goodwill and state income taxes.



LIQUIDITY AND CAPITAL RESOURCES


At June 30, 1999, Nabi's credit agreement provided for a $45 million revolving
credit facility subject to certain borrowing base restrictions as defined in the
agreement which matures in September 2002, and a $5.0 million term loan due in
March 2000. Borrowings under the agreement totaled $27.8 million and additional
availability was approximately $8 million at June 30, 1999. The credit agreement
is secured by substantially all of Nabi's assets, requires the maintenance of
certain financial covenants and prohibits the payment of dividends.

As of June 30, 1999, Nabi's current assets exceeded current liabilities by $27.6
million as compared to a net working capital position of $42 million at December
31, 1998. Cash and cash equivalents at June 30, 1999 were $1.1 million compared
to $1 million at December 31, 1998. The primary source of cash during 1999 was
operations, including a reduction of trade receivables and inventories. Net cash
provided by operating activities was $16.9 million representing an improvement
of $6.8 million from the comparable 1998 six months. The primary uses of cash
during the first half of 1999 were capital expenditures, principally associated
with the Company's manufacturing facility in Boca Raton, Florida, and a $9.7
million reduction of borrowings under the revolving credit agreement.

Projected capital expenditures for the remainder of 1999 include costs
associated with the Boca Raton manufacturing facility, including capitalized
interest, development of information systems and related expenditures, and
antibody collection center renovations. Nabi believes that cash flow from
operations and its available bank credit facilities will be sufficient to meet
its anticipated cash requirements for 1999. The Company is also in the process
of seeking additional cash to fund the development of its pharmaceutical product
pipeline from strategic alliances and additional funding from new or existing
credit facilities.


YEAR 2000


Nabi continues to assess the potential impact of the Year 2000 computer
processing issue on its management and information systems. Key financial and
operational systems have been evaluated for Year 2000 compliance. During 1998, a
cross-functional team was established to identify and address Year 2000 issues
for other information systems, equipment, other business systems and external
supplier and customer relationships.

The Company's program to address Year 2000 readiness has four overlapping
phases. Phase I, the identification and assessment of systems, equipment and
business relationships associated with Nabi's business critical processes, has
been completed. For these business critical processes, the Company is focusing
its efforts on Phase II, the testing of Year 2000 readiness for the associated
internal systems and equipment and the inquiry/audit of Year 2000 readiness for
external suppliers and customers, Phase III, the renovation or replacement of
the associated systems, equipment or business relationships that will not be
Year 2000 ready, including re-testing as required, and Phase IV, contingency
planning to mitigate the potential effect of issues which may be so deeply
embedded in the identified business critical processes that they are beyond the
Company's ability to identify and control.

As indicated above, Nabi has completed its initial assessment phase of
addressing Year 2000 issues. For its business critical processes, the Company is
currently testing systems and equipment, and is concurrently renovating or
replacing any systems or equipment as needed. In addition, Nabi has initiated
communications with any associated key external suppliers and customers and is
assessing the responses received. Nabi's goal is to complete all significant
required testing of changes to systems, equipment or processes and contingency
planning by the end of the third quarter of 1999.

The Company will utilize both internal and external resources in its Year 2000
efforts. The additional cost to achieve Year 2000 readiness is currently
estimated at $3 to $5 million dollars, including expense and capital
expenditures, not all of which are incremental to the Company's operations.
These expenditures will primarily be incurred during 1999 and will be funded by
a combination of operating cash flows, bank credit facilities, and operating and
capital lease agreements. Approximately 25% of Nabi's 1999 information
technology planned expenditures will be directly attributable to Year 2000
remediation efforts. Year 2000 related expenditures were approximately $620,000
in the second quarter of 1999.

The Company's efforts in these areas are ongoing. As of June 1999, based on the
work completed to date, Nabi believes that the software, equipment and other
systems related to its business critical processes are Year 2000 ready or that
it will be able to renovate or replace, in a timely manner, any element, which
if not Year 2000 ready could be expected to have a significant, adverse effect
on Nabi's ability to deliver products or services. However, there can be no
assurance that the Company's efforts will be successful. If they are not, the
Company's operations or financial condition may be materially and adversely
affected.


FACTORS TO BE CONSIDERED

The parts of this Quarterly Report on Form 10-Q captioned "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Legal Proceedings" contain certain forward-looking statements which involve
risks and uncertainties. Readers should refer to a discussion under "Factors to
be Considered" contained in Nabi's Annual Report on Form 10-K for the year ended
December 31, 1998 concerning certain factors that could cause Nabi's actual
results to differ materially from the results anticipated in such
forward-looking statements. Said discussion is hereby incorporated by reference
into this Quarterly Report.


PART II  OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

Nabi is a party to litigation in the ordinary course of business. In addition,
Nabi is a co-defendant with various other parties in several suits filed in the
U.S. by, or on behalf of, individuals who claim to have been infected with HIV
as a result of either using HIV-contaminated products made by the defendants
other than Nabi or having familial relations with those so infected. Nabi does
not believe that any such litigation will have a material adverse effect on its
business, financial position or results of operations.
