               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference.

         The following documents previously filed by Impax with the SEC are
incorporated herein by reference:

                  (a) Our Annual Report on Form 10-K 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 reports and other 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 $7,000,000.

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.

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 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

                                      II-2
<PAGE>


                 (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) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, as amended, each
filing of the registrant's annual report pursuant to Section 13(a) or Section
13(d) of the Securities Exchange Act of 1934, as amended (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Securities Exchange Act of 1934, as amended) that is incorporated
by reference in the Registration Statement shall be deemed to be a new
Registration Statement relating to the securities offered therein and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (c) The undersigned registrant hereby undertakes that, 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.

                      (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

                      reports filed for the purpose of updating such

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
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 $7,000,000.

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.

------   -----------

5.1      Opinion of Blank Rome Comisky & McCauley LLP.

10.1     Impax Laboratories, Inc. 2001 Employee Stock Purchase 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 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

                                      II-2
(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) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, as amended, each
filing of the registrant's annual report pursuant to Section 13(a) or Section
13(d) of the Securities Exchange Act of 1934, as amended (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Securities Exchange Act of 1934, as amended) that is incorporated
by reference in the Registration Statement shall be deemed to be a new
Registration Statement relating to the securities offered therein and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (c) The undersigned registrant hereby undertakes that, 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.
