                          IMPAX REPORTS RECORD REVENUES
                     IN THE FOURTH QUARTER AND THE YEAR 2002
                         - Files Four ANDAs in Quarter-

HAYWARD, Calif (February 12, 2003) - IMPAX Laboratories, Inc. (NASDAQ NM: IPXL)
today reported financial results for the three and twelve months ended December
31, 2002.

Revenues for the fourth quarter of 2002 were $8,400,000, up more than 400%
compared with total revenues of $2,025,000 in the prior year's fourth quarter,
and up more than 11% compared with total revenues of $7,538,000 in the third
quarter of 2002. The significant year-over-year increase came on additional
sales of Fludrocortisone Acetate Tablets, introduced at the end of the first
quarter of 2002, Minocycline Hydrochloride Capsules launched in the third
quarter of 2002, Rimantadine Hydrochloride Tablets launched in the fourth
quarter of 2002, higher Lipram sales, and lower product returns.

The net loss for the 2002 fourth quarter was $3,471,000, or $(0.07) per share,
compared with a net loss of $6,854,000, or $(0.15) per share in the prior year
fourth quarter, which included goodwill amortization of approximately $876,000,
or $(0.02) per share. Net loss narrowed due to increased sales, which partially
offset increases in research and development, and operating expenses. Further,
results included a benefit from the reversal of the interest expense on the
refundable deposit from Teva under its strategic alliance agreement, of
approximately $1,595,000, or $(0.03) per share.

For the twelve months ended December 31, 2002, the Company reported total
revenues of $24,515,000, up more than 370%, compared with total revenues of
$6,591,000 in the previous year. The significant year-over-year increase came on
the ramp up of sales of Fludrocortisone Acetate Tablets, introduced at the end
of the first quarter of 2002, Minocycline Hydrochloride Capsules launched in the
third quarter of 2002, Rimantadine Hydrochloride Tablets launched in the fourth
quarter of 2002, Terbutaline Sulfate Tablets introduced since July 2001, higher
Lipram sales, and lower product returns.

The net loss for the twelve months ended December 31, 2002, was $20,040,000, or
$(0.42) per share, compared with a net loss of $25,111,000, or $(0.60) per
share, in the previous year, which included goodwill amortization of $3,504,000,
or $(0.08) per share. Net loss narrowed due to increased sales, which partially
offset increases in research and development, and operating expenses. Further,
results included a benefit from the reversal of the interest expense on the
refundable deposit from Teva of approximately $675,000, or $(0.01) per share.


Cash, cash equivalents and short-term investments were $20.2 million at December
31, 2002, compared with $35.5 million at December 31, 2001. The balance at
December 31, 2002 included $10 million in restricted cash that serves as
collateral for the $25 million revolving credit facility and term loan agreement
signed with Congress Financial in October 2002.

"The fourth quarter continues our sequential quarter improvement," said Barry R.
Edwards, Co- CEO. "We are looking forward to increasing sales throughout 2003,
as we receive U.S. Food and Drug Administration (FDA) marketing approval for new
products."

Larry Hsu, Ph.D., President, added: "We are very pleased that our development
team reached the high end of our goal by filing eight applications in 2002, four
of which were filed in the fourth quarter. This marks the third year in a row
that we have filed eight applications. Once again, for 2003, we expect to be
able to file at least six new applications with the FDA."

IMPAX has 19 applications pending at the FDA, including three tentatively
approved, that address more than $5.8 billion in U.S. branded product sales for
the 12 months ended September 30, 2002. Fourteen of these filings were made
under Paragraph IV of the Hatch-Waxman Amendments.
