                            STOCK PURCHASE AGREEMENT

     This STOCK PURCHASE AGREEMENT is dated as of March 23, 2000 between Impax
Laboratories, Inc., a Delaware corporation (the "Company"), and the Purchaser
listed on the signature page of this Agreement (the "Purchaser").

                              W I T N E S S E T H :
                              ---------------------

     WHEREAS, the Company desires to issue and sell to the Purchaser, and the
Purchaser desires to purchase from the Company, shares of the Company's Series 2
Convertible Preferred Stock, par value $.01 per share (the "Series 2 Convertible
Preferred Stock"), upon the terms and provisions hereinafter set forth;

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth herein and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

SECTION 1. SALE AND PURCHASE OF PREFERRED STOCK

     (a) The Company agrees to sell to the Purchaser and, subject to the terms
and conditions hereof and in reliance upon the representations and warranties of
the Company contained herein or made pursuant hereto, the Purchaser agrees to
purchase from the Company at the Closing provided for in Section 2 hereof, the
number of shares of Series 2 Convertible Preferred Stock set forth opposite the
Purchaser's name on Schedule 1 hereto. The shares of Series 2 Convertible
Preferred Stock being acquired under this Agreement and by the other Purchasers
under the other Stock Purchase Agreements (as hereinafter defined) are
collectively referred to herein as the "Shares", containing rights and
privileges as more fully set forth in the Series 2 Certificate of Designations
of the Company in the form attached hereto as Exhibit A (the "Series 2
Certificate of Designations").

     (b) The aggregate purchase price to be paid to the Company by the Purchaser
for the Shares to be purchased by the Purchaser pursuant to this Agreement shall
be the amount set forth opposite the Purchaser's name on Schedule 1 hereto. No
further payment shall be required from the Purchaser for the Shares. The parties
further acknowledge and agree that the Shares do not constitute "preferred
stock" as that term is used in Section 305(b)(4) of the Code and Treasury
Regulation ss. 1.305-5(a) and agree not to take any position inconsistent with
the


<PAGE>


characterization of the Shares as common stock for purposes of Section 305 of
the Code on any Tax Return or before any Taxing Authority.

     (c) The Shares are being sold to the purchasers listed on Schedule 1 hereto
(the "Purchasers") pursuant to this Agreement and the other Series 2 Convertible
Preferred Stock Purchase Agreements (such agreements collectively, as from time
to time assigned, supplemented or amended or as the terms thereof may be waived,
the "Stock Purchase Agreements"). Each Stock Purchase Agreement shall be dated
the date hereof and shall be identical except as to the identities of the
respective Purchasers. The sale of Shares to each Purchaser under each Stock
Purchase Agreement is to be a separate sale, and no Purchaser shall have any
liability under any Stock Purchase Agreement other than the Stock Purchase
Agreement to which it is a party.

     (d) The Company will use the proceeds from the sale of the Shares, together
with other funds it will receive on the Closing Date to fund future development
opportunities and for working capital and general corporate purposes.

SECTION 2. CLOSINGS

     (a) Subject to the terms and conditions hereof, the closing of the purchase
and sale of the Shares to be purchased by the Purchaser and the other Purchasers
will take place at the offices of Morgan, Lewis & Bockius LLP, 101 Park Avenue,
New York, New York at 10:00 A.M., New York City time on March 23, 2000, or such
other time and date as shall be mutually agreed to by the Company and the
Purchasers (the "Closing") (such time and date are herein referred to as the
"Closing Date").

     (b) Subject to the terms and conditions hereof, at the Closing (i) the
Company will deliver to each Purchaser a certificate registered in the
Purchaser's name (or the name of its nominee, if any, as specified on Schedule 1
hereto) evidencing the number of Shares set forth opposite the Purchaser's name
on Schedule 1 and (ii) upon the Purchaser's receipt thereof, the Purchaser will
deliver to the Company a certified or official bank check (or wire transfer) in
an amount equal to the aggregate purchase price (as specified in Section 1(b)
hereof) for the Shares to be purchased by the Purchaser payable to the order of
the Company in federal or other immediately available funds.

SECTION 3. DEFINITIONS

          Leases) shall be computed by discounting, to the date of

          annum, the minimum amount of future rental payments that will be due
          under the related documentation, including rental payments that may be

          excluding any amounts in respect of insurance on, taxes on and/or

     4.6. Disclosure Materials; Other Information.

     (a) The Company has previously furnished to the Purchaser the materials
described on Schedule 4.6 hereto (the "Disclosure Material"). The audited and
unaudited financial statements referred to or contained in the materials
referred to on Schedule 4.6 fairly present the consolidated financial condition
of the Company as of the respective dates thereof and the consolidated results
of the operations of the Company for such periods and have been prepared in
accordance with GAAP, except that any such unaudited statements may omit notes
and may be subject to year-end adjustment.

     (b) Since December 31, 1999, (i) the business of the Company has been
conducted in the ordinary course and (ii) there has been no material adverse
change in the assets, properties, liabilities, business, affairs, results of
operations, condition (financial or otherwise) or prospects of the Company on a
consolidated basis. As of the Closing Date and as of the date hereof, there are
no material liabilities of the Company which would be required to be provided
for in a consolidated balance sheet of the Company as of either such date
prepared in accordance with GAAP, other than liabilities provided for in the
financial statements referred to in Section 4.6(a). Since December 31, 1999, no
amount or property has directly or indirectly been declared,


                                       18

<PAGE>


ordered, paid, made or set aside for any Restricted Payment nor has any such
action been agreed to.

     (c) There are no material liabilities, contingent or otherwise, of the
Company that have not been disclosed in the financial statements referred to in
Section 4.6(a) or otherwise disclosed in the Disclosure Material.

     (d) The financial projections included in the Disclosure Material conform
with the internal operating forecasts of the Company and were based on
reasonable assumptions when made and have been prepared in good faith.

     (e) There is no fact known to the Company which is not in the Disclosure
Material and which materially and adversely affects, or in the future would be
reasonably likely (as far as the Company currently can reasonably foresee) to
materially and adversely affect, the assets, properties, liabilities, business,
affairs, results of operations, condition (financial or otherwise) or prospects
of the Company on a consolidated basis.

     4.7. Litigation.

     There is no action, suit, proceeding, investigation or claim pending or, to
the knowledge of the Company, threatened in law, equity or otherwise before any
court, administrative agency or arbitrator which (i) questions the validity of
the Stock Purchase Agreements, the Series 2 Certificate of Designations, the
Series 1 Certificate of Designations, the Series 1 Waiver, the Stockholders'
Agreement, the Stockholders' Agreement Amendment, the Registration Rights
Agreement, the Registration Rights Amendment, the Shares or the Conversion
Shares, or (iii) might result in a material adverse change in the assets,
properties, liabilities, business, affairs, results of operations, condition
(financial or otherwise) or prospects of the Company on a consolidated basis.

     4.8. Taxes.

     The Company has duly and timely filed all Tax Returns required to be filed
by it, and each such Tax Return correctly and completely reflects the Tax
liability and all other information required to be reported thereon. The Company
has paid or caused to be paid all Taxes (whether or not reflected on such Tax
Returns) that are due and payable. The provision for Taxes due by the Company in
the most recent financial statement included in the Disclosure Material is
sufficient for all unpaid Taxes, being current Taxes not yet due and payable, of
the Company, as of the end of the period covered by such financial statement,
and as of the Closing Date, such provision, as adjusted for the passage of time
through such date, will be sufficient for the then-accrued and unpaid Taxes not
yet due and payable of the Company. No Tax Returns of the Company have ever been
audited by any Taxing Authority, there is no dispute concerning any Tax
liability of the Company either threatened, claimed or raised by any Taxing
Authority, and the Company does not expect any Taxing Authority to assess
additional Taxes against or in


                                       19

<PAGE>


respect of it for any past period. The Company has withheld and paid, or, if not
yet due for payment, set aside in accounts for such purposes, all Taxes required
to have been withheld in connection with amounts paid or owing to any employee,
creditor, independent contractor or other third party. Other than stamp taxes,
the Company has no liability for Taxes of any Person other than the Company (i)
as a transferee or successor, (ii) by contract, or (iii) otherwise. There are no
applicable Taxes payable by the Company in connection with the execution and
delivery of the Stock Purchase Agreements, the Series 1 Waiver, the
Stockholders' Agreement, the Stockholders' Agreement Amendment, the Registration
Rights Agreement or the Registration Rights Amendment or the issuance by the
Company of the Shares or the Conversion Shares.

occurred with respect to any Benefit Plan or any Plan maintained by an ERISA
Affiliate since the effective date of said section 4043 for which notice is not

3(37) of ERISA.

     (f) No direct, contingent or secondary liability has been incurred or is

                                       20

<PAGE>


     (g) Neither the Company nor any ERISA Affiliate has incurred any liability
for any tax imposed under section 4971 through 4980B of the Code or civil
liability under section 502(i) or (l) of ERISA.

     (h) No benefit under any Benefit Plan, including, without limitation, any
severance or parachute payment plan or agreement, will be established or become
accelerated, vested or payable by reason of any transaction contemplated under
this Agreement.

termination of an employee's employment, except as required by Part 6 of
Subtitle B of Title I of ERISA or section 4980B of the Code or any State laws
requiring continuation of benefits coverage following termination of employment.

     (j) No suit, action or other litigation (excluding claims for benefits
incurred in the ordinary course of plan activities and any other claim which
could reasonably be expected to result in a material liability or expense to the
Company) has been brought or, to the knowledge of the Company, threatened
against or with respect to any Benefit Plan and there are no facts or
circumstances known to the Company that could reasonably be expected to give
rise to any such suit, action or other litigation.

     (k) All contributions to Benefit Plans that were required to be made under
such Benefit Plans have been made, and all benefits accrued under any unfunded
Benefit Plan have been paid, accrued or otherwise adequately reserved in
accordance with generally accepted accounting principles, all of which accruals
under unfunded Benefit Plans are as disclosed in Exhibit B, and the Company has
performed all material obligations required to be performed under all Benefit
Plans.

     (l) The execution, delivery and performance of the Stock Purchase
Agreements, the Series 1 Waiver, the Stockholders' Agreement, the Stockholders'
Agreement Amendment, the Registration Rights Agreement and the Registration
Rights Amendment and the consummation of the transactions contemplated hereby
and thereby (including, without limitation, the offer, issue and sale by the
Company, and the purchase by the Purchaser of the Shares and the Conversion
Shares) will not involve any "prohibited transaction" within the meaning of
ERISA or the Code with respect to any Benefit Plan.

agents, (ii) a material breach by Purchaser of any of its representations or

or in the case of any such mutilation, upon surrender of such Share certificate
(which surrendered Share certificate shall be cancelled by the Company), the
Company will issue a new Share certificate of like tenor in lieu of such lost,
stolen, destroyed or mutilated Share certificate as if the lost, stolen,
destroyed or mutilated Share certificate were then surrendered for exchange.
