ITEM 4. DESCRIPTION OF SECURITIES.

          Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

          None.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The Registrant is organized under the laws of the State of Delaware.
Section 145 of the Delaware General Corporation Law permits a Delaware
corporation to indemnify any person who is a party (or is threatened to be made
a party) to any threatened, pending or completed action, suit or proceeding
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the corporation) by reason of the fact that he or she is
or was a director, officer, employee or agent of the corporation or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation or enterprise. A corporation may similarly
indemnify such person in the case of actions or suits brought by or in the right
of the corporation, except (unless otherwise ordered by the court) that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation.

     A corporation may indemnify such person against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful. Any indemnification shall be made by the
corporation only as authorized in the specific case upon a determination that
indemnification is proper in the circumstances because the person has met the
aforesaid standard of conduct. Such determination shall be made (1) by a
majority vote of the directors who were not parties to the action, suit, or
proceeding, whether or not a quorum, or (2) if there are no such directors, or
if such directors so direct, by independent legal counsel in a written opinion,
or (3) by the stockholders. To the extent that a director, officer, employee or
agent of a corporation has been successful on the merits, or otherwise, in
defense of any action, suit or proceeding described above, or in defense of any
claim, issue or matter therein, such person shall be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred in
connection therewith. The statute also provides that it is not exclusive of any
other rights to which those seeking indemnification may be entitled under any
by-laws, agreement, vote of stockholders or disinterested directors or
otherwise. The Registrant's By-Laws provide for the indemnification of its
directors and officers to the fullest extent permitted by law.

     Section 102(b)(7) of the Delaware General Corporation Law allows a
Delaware corporation to limit or eliminate the personal liability of directors
to the corporation and its stockholders for monetary damages for breach of
fiduciary duty as a director. However, this provision excludes any limitation
on liability (1) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (2) for acts or omissions not in good faith or
which involved intentional misconduct or a knowing violation of law, (3) for
intentional or negligent payment of unlawful dividends or stock purchases or
redemptions, or (4) for any transaction from which the director derived an
improper benefit. Moreover, while this provision provides directors with
protection against awards for monetary damages for breaches of their duty of
care, it does not eliminate such duty. Accordingly, this provision will have no
effect on the availability of equitable remedies such as an injunction or
rescission based on a director's breach of his or her duty of care. Finally,
this provision applies to an officer of a corporation only if he or

                                       3
<PAGE>   4
she is a director of such corporation and is acting in his or her capacity as
director, and does not apply to officers of the corporation who are not
directors.

     The Registrant's Certificate of Incorporation provides for the limitation
on liability permitted by Section 102(b)(7). The Registrant maintains directors
and officers' liability insurance.

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:

                    (i) To include any prospectus required by Section 10(a)(3)
               of the Securities Act of 1933;

                    (ii) To 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 set forth in the registration statement.
               Notwithstanding the foregoing, any increase or decrease in volume
               or securities offered (if the total dollar value of securities
               offered would not exceed that which was registered) and any
               deviation from the low or


                                       4
<PAGE>   5
             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 percent change in the maximum aggregate
             offering price set forth in the "Calculation of Registration Fee"
             table in the effective registration statement;

                  (iii)     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;

         provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
apply if the registration statement is on Form S-3, Form S-8 or Form F-3 and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.

             (2)  That, for the purpose of determining any liability under the
         Securities Act of 1933, 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.

             (3)  To remove from registration by means of a post-effective
         amendment of 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 of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (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) 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.

         (h)  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.

ITEM 4. DESCRIPTION OF SECURITIES.

          Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

          None.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The Registrant is organized under the laws of the State of Delaware.
Section 145 of the Delaware General Corporation Law permits a Delaware
corporation to indemnify any person who is a party (or is threatened to be made
a party) to any threatened, pending or completed action, suit or proceeding
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the corporation) by reason of the fact that he or she is
or was a director, officer, employee or agent of the corporation or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation or enterprise. A corporation may similarly
indemnify such person in the case of actions or suits brought by or in the right
of the corporation, except (unless otherwise ordered by the court) that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation.

     A corporation may indemnify such person against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful. Any indemnification shall be made by the
corporation only as authorized in the specific case upon a determination that
indemnification is proper in the circumstances because the person has met the
aforesaid standard of conduct. Such determination shall be made (1) by a
majority vote of the directors who were not parties to the action, suit, or
proceeding, whether or not a quorum, or (2) if there are no such directors, or
if such directors so direct, by independent legal counsel in a written opinion,
or (3) by the stockholders. To the extent that a director, officer, employee or
agent of a corporation has been successful on the merits, or otherwise, in
defense of any action, suit or proceeding described above, or in defense of any
claim, issue or matter therein, such person shall be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred in
connection therewith. The statute also provides that it is not exclusive of any
other rights to which those seeking indemnification may be entitled under any
by-laws, agreement, vote of stockholders or disinterested directors or
otherwise. The Registrant's By-Laws provide for the indemnification of its
directors and officers to the fullest extent permitted by law.

     Section 102(b)(7) of the Delaware General Corporation Law allows a
Delaware corporation to limit or eliminate the personal liability of directors
to the corporation and its stockholders for monetary damages for breach of
fiduciary duty as a director. However, this provision excludes any limitation
on liability (1) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (2) for acts or omissions not in good faith or
which involved intentional misconduct or a knowing violation of law, (3) for
intentional or negligent payment of unlawful dividends or stock purchases or
redemptions, or (4) for any transaction from which the director derived an
improper benefit. Moreover, while this provision provides directors with
protection against awards for monetary damages for breaches of their duty of
care, it does not eliminate such duty. Accordingly, this provision will have no
effect on the availability of equitable remedies such as an injunction or
rescission based on a director's breach of his or her duty of care. Finally,
this provision applies to an officer of a corporation only if he or

                                       3
4
she is a director of such corporation and is acting in his or her capacity as
director, and does not apply to officers of the corporation who are not
directors.

     The Registrant's Certificate of Incorporation provides for the limitation
on liability permitted by Section 102(b)(7). The Registrant maintains directors
and officers' liability insurance.

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:

                    (i) To include any prospectus required by Section 10(a)(3)
               of the Securities Act of 1933;

                    (ii) To 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 set forth in the registration statement.
               Notwithstanding the foregoing, any increase or decrease in volume
               or securities offered (if the total dollar value of securities
               offered would not exceed that which was registered) and any
               deviation from the low or

                                       4
5
             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 percent change in the maximum aggregate
             offering price set forth in the "Calculation of Registration Fee"
             table in the effective registration statement;

                  (iii)     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;

         provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
apply if the registration statement is on Form S-3, Form S-8 or Form F-3 and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.

             (2)  That, for the purpose of determining any liability under the
         Securities Act of 1933, 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.

             (3)  To remove from registration by means of a post-effective
         amendment of 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 of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (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) 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.

         (h)  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.

certifies that it has reasonable grounds to believe that it meets all of 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 the Township of Little Falls, State of New Jersey, on the 29th
day of June, 2000.
