               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 for the fiscal year ended
                   December 31, 2001;

             (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.

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 arising
                          after the effective date of the registration statement
                          (or the most recent post-effective amendment thereof)
                          which, individually or in the aggregate, represent a
                          fundamental change in the information in the
                          registration statement. Notwithstanding the foregoing,
                          any increase or decrease in volume of securities


                                      II-2

<PAGE>

                          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

                   (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 registration hereby undertakes that, for purposes
of determining any liability under the Securities Act of 1933, each filing of
the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 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) 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

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 for the fiscal year ended
                   December 31, 2001;

             (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

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 $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.

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 arising
                          after the effective date of the registration statement
                          (or the most recent post-effective amendment thereof)
                          which, individually or in the aggregate, represent a
                          fundamental change in the information in the
                          registration statement. Notwithstanding the foregoing,
                          any increase or decrease in volume of securities

                                      II-2
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

                   (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 registration hereby undertakes that, for purposes
of determining any liability under the Securities Act of 1933, each filing of
the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 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) 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, in Philadelphia Pennsylvania on the date indicated.
