               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


Item 3.  Incorporation of Certain Documents by Reference.

     The following documents previously filed by Impax with the SEC are hereby
incorporated by reference in this registration statement:

     (a)  Our Annual Report on Form 10-K (File No. 33-99310) for the fiscal
          year ended December 31, 1999;

     (b)  All other reports filed by us pursuant to Section 13(a) or 15(d) of
          the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
          since the end of the fiscal year covered by the Annual Report on Form
          10-K referred to in (a) above; and

     (c)  The description of our common stock, which is incorporated by
          reference in our registration statement on Form 8-A 12g/A (File No.
          33-99310-NY) filed on December 5, 1997 under the Exchange Act,
          including any amendments or reports filed for the purpose of updating
          such description.

     All documents subsequently filed by us with the SEC pursuant to Sections
13(a), 13(c), 14 or 15(d) of the Exchange Act, after the date of this
registration statement, but prior to the filing of a post-effective amendment
which indicates that all securities offered hereby have been sold or which
deregisters all securities then remaining unsold, shall be deemed to be
incorporated by reference in this registration statement and to be a part
thereof from the date of the filing of such documents.

Item 4.  Description of Securities.

         Not Applicable.

Item 5.  Interests of Named Experts and Counsel.

         Not Applicable.

Item 6.  Indemnification of Directors and Officers.

Impax is incorporated under the laws of the State of Delaware.

     Section 145 of the Delaware General Corporation Law, referred to as the
DGCL, authorizes a court to award, or a corporation's board to directors to
grant, indemnity to directors and officers in terms sufficiently broad to permit
such indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended. Impax's Certificate of Incorporation, as amended, and By-laws
provide for indemnification of Impax's officers and directors to the maximum
extent permitted by Delaware law.

                                      II-1
<PAGE>

     The DGCL also provides that a Delaware corporation may include in its
certificate of incorporation a provision which eliminates personal liability of
its directors to the corporation and its stockholders, in certain circumstances,
for monetary damages arising from a breach of the director's duty of care.
Impax's Certificate of Incorporation, as amended, provides a limitation of a
director's liability for monetary damages for breach of fiduciary duty,
including gross negligence, except in circumstances involving certain wrongful
acts, such as the breach of a director's duty of loyalty or acts or omissions
not in good faith or which involve intentional misconduct of a knowing violation
of law.

     Impax has obtained directors' and officers' liability insurance for the
benefit of Impax and its stockholders in the amount of $5,000,000.

Item 7.  Exemption from Registration Claimed.

         Not Applicable.

Item 8.  Exhibits.

         The following exhibits are filed as part of this registration statement
or, where so indicated, have been previously filed and are incorporated hereby
by reference.

Number   Description

10.1     Impax Laboratories, Inc. 1999 Equity Incentive Plan.

23.1     Consent of PricewaterhouseCoopers LLP.

23.2     Consent of Blank Rome Comisky & McCauley LLP (included in Exhibit 5.1).

24.1     Power of Attorney (included on signature page).


Item 9.  Undertakings.

         (a)  The undersigned will:

              (1)  File, during any period in which it offers or sells
                   securities, a post-effective amendment to this registration
                   statement to:

                   (i)   Include any prospectus required by section 10(a)(3) of
                         the Securities Act of 1933, as amended;

                   (ii)  Reflect in the prospectus any facts or events which,
                         individually or together, represent a fundamental
                         change in the information in the registration
                         statement. Notwithstanding the foregoing, any increase
                         or decrease in volume of securities offered (if the
                         total dollar value of securities offered would not
                         exceed that which was registered) and any deviation
                         from the low or high end of the estimated maximum
                         offering

                                      II-2
<PAGE>

                         range may be reflected in the form of prospectus filed
                         with the Commission pursuant to Rule  424(b) if, in
                         the aggregate, the changes in volume and price
                         represent no more than a 20% change in the
                         maximum aggregate offering price set forth in the
                         "Calculation of Registration Fee" table in the
                         effective registration statement; and

                   (iii) Include any additional or changed material information
                         on the plan of distribution.

     Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
the registration statement is on Form S-3 or S-8, and the information required
in a post-effective amendment is incorporated by reference from periodic reports
filed by the registrant under the Securities Exchange Act of 1934, as amended.

              (2)  For determining liability under the Securities Act of
                   1933, as amended, treat each such post-effective amendment
                   as a new registration statement of the securities offered,
                   and the offering of the securities at that time to be the
                   initial bona fide offering.

              (3)  File a post-effective amendment to remove from registration
                   any of the securities that remain unsold at the end of the
                   offering.

     (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

PART II

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.  Incorporation of Certain Documents by Reference.

     The following documents previously filed by Impax with the SEC are hereby
incorporated by reference in this registration statement:

     (a)  Our Annual Report on Form 10-K (File No. 33-99310) for the fiscal
          year ended December 31, 1999;

     (b)  All other reports filed by us pursuant to Section 13(a) or 15(d) of
          the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
          since the end of the fiscal year covered by the Annual Report on Form
          10-K referred to in (a) above; and

     (c)  The description of our common stock, which is incorporated by
          reference in our registration statement on Form 8-A 12g/A (File No.
          33-99310-NY) filed on December 5, 1997 under the Exchange Act,
          including any amendments or reports filed for the purpose of updating
          such description.

     All documents subsequently filed by us with the SEC pursuant to Sections
13(a), 13(c), 14 or 15(d) of the Exchange Act, after the date of this
registration statement, but prior to the filing of a post-effective amendment
which indicates that all securities offered hereby have been sold or which
deregisters all securities then remaining unsold, shall be deemed to be
incorporated by reference in this registration statement and to be a part

Item 4.  Description of Securities.

         Not Applicable.

Item 5.  Interests of Named Experts and Counsel.

         Not Applicable.

Item 6.  Indemnification of Directors and Officers.

Impax is incorporated under the laws of the State of Delaware.

     Section 145 of the Delaware General Corporation Law, referred to as the
DGCL, authorizes a court to award, or a corporation's board to directors to
grant, indemnity to directors and officers in terms sufficiently broad to permit
such indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended. Impax's Certificate of Incorporation, as amended, and By-laws
provide for indemnification of Impax's officers and directors to the maximum
extent permitted by Delaware law.

                                      II-1
The DGCL also provides that a Delaware corporation may include in its
certificate of incorporation a provision which eliminates personal liability of
its directors to the corporation and its stockholders, in certain circumstances,
for monetary damages arising from a breach of the director's duty of care.
Impax's Certificate of Incorporation, as amended, provides a limitation of a
director's liability for monetary damages for breach of fiduciary duty,
including gross negligence, except in circumstances involving certain wrongful
acts, such as the breach of a director's duty of loyalty or acts or omissions
not in good faith or which involve intentional misconduct of a knowing violation
of law.

     Impax has obtained directors' and officers' liability insurance for the
benefit of Impax and its stockholders in the amount of $5,000,000.

Item 7.  Exemption from Registration Claimed.

         Not Applicable.

Item 8.  Exhibits.

         The following exhibits are filed as part of this registration statement
or, where so indicated, have been previously filed and are incorporated hereby
by reference.

Number   Description

5.1      Opinion of Blank Rome Comisky & McCauley LLP.

10.1     Impax Laboratories, Inc. 1999 Equity Incentive Plan.

23.1     Consent of PricewaterhouseCoopers LLP.

23.2     Consent of Blank Rome Comisky & McCauley LLP (included in Exhibit 5.1).

24.1     Power of Attorney (included on signature page).

Item 9.  Undertakings.

         (a)  The undersigned will:

              (1)  File, during any period in which it offers or sells
                   securities, a post-effective amendment to this registration
                   statement to:

                   (i)   Include any prospectus required by section 10(a)(3) of
                         the Securities Act of 1933, as amended;

                   (ii)  Reflect in the prospectus any facts or events which,
                         individually or together, represent a fundamental
                         change in the information in the registration
                         statement. Notwithstanding the foregoing, any increase
                         or decrease in volume of securities offered (if the
                         total dollar value of securities offered would not
                         exceed that which was registered) and any deviation
                         from the low or high end of the estimated maximum
                         offering

                                      II-2
range may be reflected in the form of prospectus filed
                         with the Commission pursuant to Rule  424(b) if, in
                         the aggregate, the changes in volume and price
                         represent no more than a 20% change in the
                         maximum aggregate offering price set forth in the
                         "Calculation of Registration Fee" table in the
                         effective registration statement; and

                   (iii) Include any additional or changed material information
                         on the plan of distribution.

     Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
the registration statement is on Form S-3 or S-8, and the information required
in a post-effective amendment is incorporated by reference from periodic reports
filed by the registrant under the Securities Exchange Act of 1934, as amended.

              (2)  For determining liability under the Securities Act of
                   1933, as amended, treat each such post-effective amendment
                   as a new registration statement of the securities offered,
                   and the offering of the securities at that time to be the
                   initial bona fide offering.

              (3)  File a post-effective amendment to remove from registration
                   any of the securities that remain unsold at the end of the
                   offering.

     (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                                      II-3
SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, as amended,
the registrant certifies that it has reasonable grounds to believe that it meets
all the requirements for filing on Form S-8 and has duly caused this
registration statement to be signed on its behalf by the undersigned, thereunto
duly authorized, on the date indicated.
