Item 6.           Indemnification of Directors and Officers.
                  -----------------------------------------

      The registrant is organized under the laws of the State of New Jersey. The
New Jersey Business Corporation Act provides that a New Jersey corporation has
the power to indemnify its directors, officers, employees and other agents
against expenses and liabilities in connection with any proceeding involving
such person by reason of his/her being or having been a director, officer,
employee or other agent, other than a proceeding by or in the right of the
corporation, if he/she acted in good faith and in a manner he/she reasonably
believed to be in or not opposed to the best interests of the corporation and,
with respect to any criminal proceeding, such person had no reasonable cause to
believe his/her conduct was unlawful. Expenses incurred by a director, officer,
employee or other agent in connection with a proceeding may be, under certain
circumstances, paid by the corporation before the final disposition of the
proceeding as authorized by the board of directors. The power to indemnify and
pay expenses under the New Jersey Business Corporation Act does not exclude
other rights, including the right to be indemnified against liabilities and
expenses incurred in proceedings by or in the right of the corporation, to which
a director, officer, employee or other agent of the corporation may be entitled
to under a certificate of incorporation, by-law, agreement, vote of
shareholders, or otherwise; provided that no indemnification is permitted to be
made to or on behalf of such person if a judgment or other final adjudication
adverse to such person establishes that his/her acts or omissions were in breach
of his/her duty of loyalty to the corporation or its shareholders, were not in
good faith or involved a violation of the law, or resulted in the receipt of
such person of an improper personal benefit.

      The New Jersey Business Corporation Act further provides that a New Jersey
corporation has the power to purchase and maintain insurance on behalf of any
director, officer, employee or other agent against any expenses incurred in any
proceeding and any liabilities asserted against him/her by reason of his/her
being or having been a director, officer, employee or other agent, whether or
not the corporation would have the power to indemnify him/her against such
expenses and liabilities under the New Jersey Business Corporation Act.

      The registrant's Certificate of Incorporation provides that directors and
officers of the registrant shall not be personally liable (in the case of
officers, for the duration of any time permitted by law) to the registrant or
its shareholders for damages for breach of any duty owed to the registrant or
its shareholders, except for liability for any breach of duty based upon an act
or omission (i) in breach of such persons' duty of loyalty to the registrant or
its shareholders, (ii) not in good faith or involving a knowing violation of law
or (iii) resulting in receipt by such persons of an improper personal benefit.

      The Certificate of Incorporation of the registrant also provides that each
person who was or is made a party or is threatened to be made a party to or who
is involved in any pending, threatened or completed civil, criminal,
administrative or arbitrative action, suit or proceeding, or any appeal therein
or any inquiry or investigation which could lead to such action, suit or
proceeding (a "proceeding"), by reason of his/her being or having been a
director, officer, employee, or agent of the registrant or of any constituent
corporation absorbed by the registrant in a consolidation or merger, or by
reason of his/her being or having been a director, officer,

                              -4-

<PAGE>

trustee, employee or agent of any other corporation (domestic or foreign) or of
any partnership, joint venture, sole proprietorship, trust, employee benefit
plan or other enterprise (whether or not for profit), serving as such at the
request of the registrant or of any such constituent corporation, or the legal
representative of any such director, officer, trustee, employee or agent, shall
be indemnified and held harmless by the registrant to the fullest extent
permitted by the New Jersey Business Corporation Act, as the same exists or may
be amended (but, in the case of any such amendment, only to the extent that such
amendment permits the registrant to provide broader indemnification rights than
said Act permitted prior to such amendment), from and against any and all
reasonable costs, disbursements and attorneys' fees, and any and all amounts
paid or incurred in satisfaction of settlements, judgments, fines and penalties,
incurred or suffered in connection with any such proceeding, and such
indemnification shall continue as to a person who has ceased to be a director,
officer, trustee, employee or agent and shall inure to the benefit of his/her
heirs, executors, administrators and assigns; provided, however, that, the
registrant shall indemnify any such person seeking indemnification in connection
with a proceeding (or part thereof) initiated by such person only if such
proceeding (or part thereof) was specifically authorized by the Board of
Directors of the registrant. The Certificate of Incorporation provides that such
right to indemnification shall be a contract right and shall include the right
to be paid by the registrant the expenses incurred in connection with any
proceeding before the final disposition of such proceeding as authorized by the
Board of Directors; provided, however, that, if the New Jersey Business
Corporation Act so requires, the payment of such expenses before the final
disposition of a proceeding shall be made only upon receipt by the registrant of
an undertaking, by or on behalf of such director, officer, employee, or agent to
reimburse the amounts so paid if it is not ultimately determined that such
person is entitled to be indemnified under the Certificate of Incorporation or
otherwise. The right to indemnification and payment of expenses provided by or
granted pursuant to the Certificate of Incorporation shall not exclude or be
exclusive of any other rights to which any person may be entitled under a
certificate of incorporation, by-law, agreement, vote of shareholders or
otherwise, provided that no indemnification shall be made to or on behalf of
such person if a judgment or other final adjudication adverse to such person
establishes that such person has not met the applicable standard of conduct
required to be met under the New Jersey Business Corporation Act.

      The registrant may purchase and maintain insurance on behalf of any
director, officer, employee or agent of the registrant or another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise
against any expenses incurred in any proceeding and any liabilities asserted
against him/her by reason of such person's being or having been such a director,
officer, employee or agent, whether or not the registrant would have the power
to indemnify such person against such expenses and liabilities under the
provisions of the Certificate of Incorporation or otherwise. The registrant
maintains such insurance on behalf of its directors and officers.

      The foregoing statements are subject to the detailed provisions of the New
Jersey Business Corporation Act and the registrant's Certificate of
Incorporation.

            23.2 Consent of Lowenstein Sandler PC (included in

            24   Powers of Attorney (included as part of the signature pages).

            99   Employment Agreement, dated April 20, 2003, between Fred Hassan
                 and Schering-Plough Corporation (incorporated by reference to
                 Exhibit 99.2 to the Registrant's Current Report on Form 8-K
                 filed April 21, 2003, File No. 001-06571).

Item 9.           Undertakings.
                  ------------

(a)  The undersigned Registrant hereby undertakes:

     (1)    To file, during any period in which offers or sales are being made,
            a post-effective amendment to this Registration Statement to include
            any material information with respect to the plan of distribution
            not previously disclosed in the Registration Statement or any
            material change to such information in the Registration Statement;

     (2)    That, for the purpose of determining any liability under the
            Securities Act of 1933, as amended (the "Securities Act"), each such
            post-effective amendment 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; and

     (3)    To remove from registration by means of post-effective amendment any
            of the securities being registered which remain unsold at the
            termination of the offering.

(b)   The undersigned Registrant hereby undertakes that, for purposes
      of determining any liability under the Securities Act, each filing of
      the Registrant's annual report pursuant to Section 13(a) or 15(d) of
      the Securities Exchange Act of 1934 (the "Exchange Act") (and, where
      applicable, each filing of an employee benefit plan's annual report
      pursuant to section 15(d) of the Exchange Act) that is incorporated by
      reference in the Registration Statement shall be deemed to be a new
      registration statement relating to


                                        -6-
<PAGE>

      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 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 Securities 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 Securities Act and will be governed by the
      final adjudication of such issue.

Item 6.           Indemnification of Directors and Officers.
                  -----------------------------------------

      The registrant is organized under the laws of the State of New Jersey. The
New Jersey Business Corporation Act provides that a New Jersey corporation has
the power to indemnify its directors, officers, employees and other agents
against expenses and liabilities in connection with any proceeding involving
such person by reason of his/her being or having been a director, officer,
employee or other agent, other than a proceeding by or in the right of the
corporation, if he/she acted in good faith and in a manner he/she reasonably
believed to be in or not opposed to the best interests of the corporation and,
with respect to any criminal proceeding, such person had no reasonable cause to
believe his/her conduct was unlawful. Expenses incurred by a director, officer,
employee or other agent in connection with a proceeding may be, under certain
circumstances, paid by the corporation before the final disposition of the
proceeding as authorized by the board of directors. The power to indemnify and
pay expenses under the New Jersey Business Corporation Act does not exclude
other rights, including the right to be indemnified against liabilities and
expenses incurred in proceedings by or in the right of the corporation, to which
a director, officer, employee or other agent of the corporation may be entitled
to under a certificate of incorporation, by-law, agreement, vote of
shareholders, or otherwise; provided that no indemnification is permitted to be
made to or on behalf of such person if a judgment or other final adjudication
adverse to such person establishes that his/her acts or omissions were in breach
of his/her duty of loyalty to the corporation or its shareholders, were not in
good faith or involved a violation of the law, or resulted in the receipt of
such person of an improper personal benefit.

      The New Jersey Business Corporation Act further provides that a New Jersey
corporation has the power to purchase and maintain insurance on behalf of any
director, officer, employee or other agent against any expenses incurred in any
proceeding and any liabilities asserted against him/her by reason of his/her
being or having been a director, officer, employee or other agent, whether or
not the corporation would have the power to indemnify him/her against such
expenses and liabilities under the New Jersey Business Corporation Act.

      The registrant's Certificate of Incorporation provides that directors and
officers of the registrant shall not be personally liable (in the case of
officers, for the duration of any time permitted by law) to the registrant or
its shareholders for damages for breach of any duty owed to the registrant or
its shareholders, except for liability for any breach of duty based upon an act
or omission (i) in breach of such persons' duty of loyalty to the registrant or
its shareholders, (ii) not in good faith or involving a knowing violation of law
or (iii) resulting in receipt by such persons of an improper personal benefit.

      The Certificate of Incorporation of the registrant also provides that each
person who was or is made a party or is threatened to be made a party to or who
is involved in any pending, threatened or completed civil, criminal,
administrative or arbitrative action, suit or proceeding, or any appeal therein
or any inquiry or investigation which could lead to such action, suit or
proceeding (a "proceeding"), by reason of his/her being or having been a
director, officer, employee, or agent of the registrant or of any constituent
corporation absorbed by the registrant in a consolidation or merger, or by
reason of his/her being or having been a director, officer,

                              -4-
trustee, employee or agent of any other corporation (domestic or foreign) or of
any partnership, joint venture, sole proprietorship, trust, employee benefit
plan or other enterprise (whether or not for profit), serving as such at the
request of the registrant or of any such constituent corporation, or the legal
representative of any such director, officer, trustee, employee or agent, shall
be indemnified and held harmless by the registrant to the fullest extent
permitted by the New Jersey Business Corporation Act, as the same exists or may
be amended (but, in the case of any such amendment, only to the extent that such
amendment permits the registrant to provide broader indemnification rights than
said Act permitted prior to such amendment), from and against any and all
reasonable costs, disbursements and attorneys' fees, and any and all amounts
paid or incurred in satisfaction of settlements, judgments, fines and penalties,
incurred or suffered in connection with any such proceeding, and such
indemnification shall continue as to a person who has ceased to be a director,
officer, trustee, employee or agent and shall inure to the benefit of his/her
heirs, executors, administrators and assigns; provided, however, that, the
registrant shall indemnify any such person seeking indemnification in connection
with a proceeding (or part thereof) initiated by such person only if such
proceeding (or part thereof) was specifically authorized by the Board of
Directors of the registrant. The Certificate of Incorporation provides that such
right to indemnification shall be a contract right and shall include the right
to be paid by the registrant the expenses incurred in connection with any
proceeding before the final disposition of such proceeding as authorized by the
Board of Directors; provided, however, that, if the New Jersey Business
Corporation Act so requires, the payment of such expenses before the final
disposition of a proceeding shall be made only upon receipt by the registrant of
an undertaking, by or on behalf of such director, officer, employee, or agent to
reimburse the amounts so paid if it is not ultimately determined that such
person is entitled to be indemnified under the Certificate of Incorporation or
otherwise. The right to indemnification and payment of expenses provided by or
granted pursuant to the Certificate of Incorporation shall not exclude or be
exclusive of any other rights to which any person may be entitled under a
certificate of incorporation, by-law, agreement, vote of shareholders or
otherwise, provided that no indemnification shall be made to or on behalf of
such person if a judgment or other final adjudication adverse to such person
establishes that such person has not met the applicable standard of conduct
required to be met under the New Jersey Business Corporation Act.

      The registrant may purchase and maintain insurance on behalf of any
director, officer, employee or agent of the registrant or another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise
against any expenses incurred in any proceeding and any liabilities asserted
against him/her by reason of such person's being or having been such a director,
officer, employee or agent, whether or not the registrant would have the power
to indemnify such person against such expenses and liabilities under the
provisions of the Certificate of Incorporation or otherwise. The registrant
maintains such insurance on behalf of its directors and officers.

      The foregoing statements are subject to the detailed provisions of the New
Jersey Business Corporation Act and the registrant's Certificate of
Incorporation.

            23.1 Consent of Deloitte & Touche LLP.

            23.2 Consent of Lowenstein Sandler PC (included in
                 Exhibit 5).

            24   Powers of Attorney (included as part of the signature pages).

            99   Employment Agreement, dated April 20, 2003, between Fred Hassan
                 and Schering-Plough Corporation (incorporated by reference to
                 Exhibit 99.2 to the Registrant's Current Report on Form 8-K
                 filed April 21, 2003, File No. 001-06571).

Item 9.           Undertakings.
                  ------------

(a)  The undersigned Registrant hereby undertakes:

     (1)    To file, during any period in which offers or sales are being made,
            a post-effective amendment to this Registration Statement to include
            any material information with respect to the plan of distribution
            not previously disclosed in the Registration Statement or any
            material change to such information in the Registration Statement;

     (2)    That, for the purpose of determining any liability under the
            Securities Act of 1933, as amended (the "Securities Act"), each such
            post-effective amendment 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; and

     (3)    To remove from registration by means of post-effective amendment any
            of the securities being registered which remain unsold at the
            termination of the offering.

(b)   The undersigned Registrant hereby undertakes that, for purposes
      of determining any liability under the Securities Act, each filing of
      the Registrant's annual report pursuant to Section 13(a) or 15(d) of
      the Securities Exchange Act of 1934 (the "Exchange Act") (and, where
      applicable, each filing of an employee benefit plan's annual report
      pursuant to section 15(d) of the Exchange Act) that is incorporated by
      reference in the Registration Statement shall be deemed to be a new
      registration statement relating to

                                        -6-
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 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 Securities 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 Securities Act and will be governed by the
      final adjudication of such issue.

                                        -7-
