Item 15.    Indemnification of Directors and Officers

     Our By-laws provide that we shall indemnify, to the extent permitted by
Delaware law, our directors, officers and employees against liabilities
(including expenses, judgments and settlements) incurred by them in connection
with any actual or threatened action, suit or proceeding to which they are or
may become parties and which arises out of their status as directors, officers
or employees.

     Sections 145(a) and 145(b) of the Delaware General Corporation Law ("DGCL")
permit a corporation to indemnify any director, officer, employee or agent of
the corporation against expenses, including attorneys' fees, judgments, fines
and amounts paid in settlement or incurred by him in connection with any
proceeding arising out of his status as director, officer, employee or agent if
such person 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, had no reasonable cause to believe his conduct was
unlawful. To the extent that such a person has been successful in defense of any
such action or claim, Section 145(c) provides that he shall be indemnified
against expenses incurred by him in connection therewith.

     As permitted by Section 102(b)(7) of the DGCL, Article Ninth of our
Certificate of Incorporation limits the personal liability of our directors to
us or our shareholders for monetary damages for breach of fiduciary duty except
for liability (i) for any breach of the director's duty of loyalty to us or our
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) under Section 174 of
the DGCL or (iv) for any transaction from which the director derived an improper
personal benefit.

Item 17.    Undertakings

     The 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 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 SEC 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;

          (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;


                                      II-2




     (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 post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (4)  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 (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 herein, and the offering of such
securities at the time shall be deemed to be the initial bona fide offering
thereof.

     (5)  For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.

     (6)  For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus 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.

     (7)  The undersigned registrant hereby under takes to file an application
for the purpose of determining the eligibility of the trustee under subsection
(a) of Section 310 of the Trust Indenture Act (the "Act") in accordance with the
rules and regulations prescribed by the Commission under Section 305(b)(2) of
the Act.

     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 said 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, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this Amendment to
Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in West Paterson, New Jersey on September 16, 2005.
