                   THREE-MONTHS ENDED MARCH 31, 1998 AND 1997

SALES. Sales for the first quarter of 1998 increased by $2.2 million to $58.6
million compared to $56.4 million for the first quarter of 1997. The increase
was primarily attributable to a substantial increase in the sales of drug
products, partially offset by a decline in specialty plasma sales.

GROSS PROFIT MARGIN. Gross profit and related margin for the first quarter of
1998 was $14 million, or 23.9% of sales, compared to $13.2 million, or 23.4% of
sales, in the first quarter of 1997. The increase in gross profit and related
margin resulted from increased sales of high-margin drug products, offset by the
effects of reduced margins on plasma product sales. Gross profits and related
margins on plasma product sales were adversely affected by under absorption of
fixed overhead as a result of reduced production levels in response to the
general disruption in the plasma industry and certain expenses associated with
process improvement initiatives within plasma operations.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSE. Selling, general and administrative
expense was $8.0 million, or 13.6% of sales, for the first quarter of 1998
compared to $4.4 million, or 7.8% of sales, in the first quarter of 1997. The
increase resulted primarily from costs associated with Nabi's restructuring
measures, sales and marketing expenses associated with increased drug product
sales and expenses associated with the implementation and ongoing support of new
information systems.

RESEARCH AND DEVELOPMENT EXPENSE. Research and development expense was $4.8
million, or 8.1% of sales, for the first quarter of 1998 compared to $3.8
million, or 6.7% of sales, in the first quarter of 1997. The increase in
expenses related primarily to costs associated with the advancement of clinical
trials for Nabi-H-BIG(R), Nabi-Altastaph(TM) and Nabi-StaphVAX(TM).

INTEREST EXPENSE. Interest expense for the first quarter of 1998 was $1.8
million, or 3% of sales, compared to $1.0 million, or 1.8% of sales, in the
first quarter of 1997. The increase was primarily attributable to interest
expense associated with higher average outstanding borrowings in the first
quarter of 1998 when compared to 1997.

OTHER FACTORS. Benefit for income taxes was $2.1 million or an effective rate of
52%, in the first quarter of 1998 compared to a $.7 million provision, or an
effective rate of 34%, in the first quarter of 1997. The 52% effective tax rate
for the first quarter of 1998 differs from the statutory rate of 35% primarily
due to foreign losses, non-deductible goodwill and alternative minimum taxes.
The 34% effective tax rate for the first quarter of 1997 differs from the
statutory rate of 35% primarily due foreign trade income, offset by the effects
of non-deductible goodwill and state income taxes.

                         LIQUIDITY AND CAPITAL RESOURCES

At March 31, 1998, 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
March 1999. Borrowings under the agreement were $36.4 million and additional
availability was approximately $9.7 million at March 31, 1998. The credit
agreement is secured by substantially all of Nabi's assets, contains covenants
requiring the maintenance of certain financial covenants and prohibits the
payment of dividends.

As of March 31, 1998, Nabi's current assets exceeded current liabilities by
$62.2 million as compared to a net working capital position of $63.9 million at
December 31, 1997.

Projected capital expenditures for 1998 include deferred validation costs,
including capitalized interest for manufacturing facilities, development of
information systems, and plasma 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 1998.

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, 1997 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.
