    hereafter be amended (the &#147;General Corporation Law&#148;), inter alia,
    provides that a Delaware corporation may indemnify any persons who were,
    are or are threatened to be made, parties 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 such corporation), by reason
    of the fact that such person is or was an officer, director, employee or
    agent of such corporation, or is or was serving at the request of such corporation
    as a director, officer, employee or agent of another corporation or enterprise.
    The indemnity may include expenses (including attorneys&#146; fees), judgments,
    fines and amounts paid in settlement actually and reasonably incurred by
    such person in connection with such action, suit or proceeding, provided
    such person acted in good faith and in a manner he reasonably believed to
    be in or not opposed to the corporation&#146;s best interests and, with
    respect to any criminal action or proceeding, had no reasonable cause to
    believe that his conduct was illegal. A Delaware corporation may indemnify
    any persons who are, were or are threatened to be made, a party to any threatened,
    pending or completed action or suit by or in the right of the corporation
    by reasons of the fact that such person was a director, officer, employee
    or agent of such corporation, or is or was serving at the request of such
    corporation as a director, officer, employee or agent of another corporation
    or enterprise. The indemnity may include expenses (including attorneys&#146; fees)
    actually and reasonably incurred by such person in connection with the defense
    or settlement of such action or suit, provided such person acted in good
    faith and in a manner he reasonably believed to be in or not opposed to the
    corporation&#146;s best interests, provided that no indemnification is permitted
    without judicial approval if the officer, director, employee or agent is
    adjudged to be liable to the corporation. Where an officer, director, employee
    or agent is successful on the merits or otherwise in the defense of any action

Item 6. Indemnification of Directors and Officers.
General Corporation Law
We are incorporated under the laws
    of the State of Delaware. Section 145 ("Section 145") of the
    General Corporation Law of the State of Delaware, as the same exists or may
    hereafter be amended (the "General Corporation Law"), inter alia,
    provides that a Delaware corporation may indemnify any persons who were,
    are or are threatened to be made, parties 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 such corporation), by reason
    of the fact that such person is or was an officer, director, employee or
    agent of such corporation, or is or was serving at the request of such corporation
    as a director, officer, employee or agent of another corporation or enterprise.
    The indemnity may include 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, provided
    such person acted in good faith and in a manner he reasonably believed to
    be in or not opposed to the corporation's best interests and, with
    respect to any criminal action or proceeding, had no reasonable cause to
    believe that his conduct was illegal. A Delaware corporation may indemnify
    any persons who are, were or are threatened to be made, a party to any threatened,
    pending or completed action or suit by or in the right of the corporation
    by reasons of the fact that such person was a director, officer, employee
    or agent of such corporation, or is or was serving at the request of such
    corporation as a director, officer, employee or agent of another corporation
    or enterprise. The indemnity may include expenses (including attorneys' fees)
    actually and reasonably incurred by such person in connection with the defense
    or settlement of such action or suit, provided such person acted in good
    faith and in a manner he reasonably believed to be in or not opposed to the
    corporation's best interests, provided that no indemnification is permitted
    without judicial approval if the officer, director, employee or agent is
    adjudged to be liable to the corporation. Where an officer, director, employee
    or agent is successful on the merits or otherwise in the defense of any action
    referred to above, the corporation must indemnify him against the expenses
    which such officer or director has actually and reasonably incurred.
Section 145 further authorizes a
    corporation to purchase and maintain insurance on behalf of any person who
    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, against any liability
    asserted against him and incurred by him in any such capacity, arising out
    of his status as such, whether or not the corporation would otherwise have
    the power to indemnify him under Section 145.
Certificate of Incorporation and By-Laws
Our Certificate of Incorporation
    and By-laws provide for the indemnification of officers and directors to
    the fullest extent permitted by the Delaware General Corporation Law.

Item 9. Undertakings.
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, 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 any of the securities being registered
    which remain unsold at the termination of the offering.
The undersigned Registrant
      hereby undertakes that, for purposes of determining any liability under
      the Securities Act of 1933 (and, where applicable, each filing of an employee
      benefit plan'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.
Insofar as the 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 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 a successful defense of any action,
    suit or proceeding) is asserted by such director, officer or controlling
    person in connection with the securities being registered hereunder, the
    Registrant will, unless in the opinion of its counsel the question has already
    been settled by controlling precedent, submit to a court of appropriate jurisdiction
    the question of 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.
SIGNATURES
Pursuant to the requirements
      of the Securities Act of 1933, the registrant 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 City of Newark, State
      of New Jersey, on this 16th day of December, 2004.
