                1.250% CONVERTIBLE SENIOR SUBORDINATED DEBENTURES



HAYWARD, Calif. (March 30, 2004) - IMPAX Laboratories, Inc. (NASDAQ NM: IPXL)
today announced the pricing of its private offering of $82 million aggregate
principal amount of 1.250% convertible senior subordinated debentures due 2024,
to qualified institutional buyers pursuant to Rule 144A under the Securities Act
of 1933, as amended (the "Securities Act"). The sale of the debentures is
expected to close on or about April 5, 2004.

Interest on the debentures will be payable on April 1 and October 1 of each
year, beginning on October 1, 2004.

Each debenture will be issued at a price of $1,000 and is convertible into IMPAX
Laboratories, Inc. common stock at an initial conversion price of approximately
$28.08 per share, subject to adjustment in certain events. Holders of the notes
may convert their debentures only if: (i) the price of Impax Laboratories,
Inc.'s common stock reaches a specific threshold; (ii) the trading price for the
debentures falls below certain thresholds; (iii) the debentures have been called
for redemption; or (iv) upon the occurrence of certain corporation transactions.

Before April 5, 2007, IMPAX Laboratories, Inc. may redeem some or all of the
debentures if the price of its common stock reaches a specific threshold, at a
redemption price that includes an additional payment on the redeemed debentures
equal to $230.77 per $1,000 principal amount of debentures, less the amount of
any interest actually paid or accrued and unpaid on the debentures. On or after
April 5, 2007, we may redeem some or all of the debentures at the redemption
prices described in IMPAX Laboratories, Inc.'s Offering Memorandum.

The debentures will be IMPAX Laboratories, Inc.'s unsecured obligations and will
be subordinated to certain of its existing and future indebtedness. On April 1,



2009, April 1, 2014 and April 1, 2019 and under certain circumstances, holders
of the debentures will have the right to require IMPAX Laboratories, Inc. to
repurchase all or any part of their debentures at a repurchase price equal to
100% of the principal amount of the debentures, plus accrued and unpaid interest
and liquidated damages, if any, to but excluding the repurchase date.

The Company has granted the initial purchasers of the debentures an option to
purchase up to an additional $13,000,000 principal amount of the debentures.
IMPAX Laboratories, Inc. plans to use the net proceeds from the offering to fund
its ongoing operations and for general corporate purposes.
