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 or she acted in good faith and in a manner he or she
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 or her 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) by a committee of
directors, who were not parties to the action, suit or proceeding, designted by
a majority of directors, who were not parties to the action, suit or proceeding,
even though less than a quorum, or (3) if there are no such directors, or if
such directors so direct, by independent legal counsel in a written opinion, or
(4) by the stockholders. To the extent that a present or former 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


                                       3

<PAGE>

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 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) of the Delaware General
Corporation Law. The Registrant maintains directors and officers' liability
insurance.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

                  Not applicable.

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 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 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 any of the securities being
                  registered which remain unsold at the termination of the
                  offering.

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 or she acted in good faith and in a manner he or she
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 or her 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) by a committee of
directors, who were not parties to the action, suit or proceeding, designted by
a majority of directors, who were not parties to the action, suit or proceeding,
even though less than a quorum, or (3) if there are no such directors, or if
such directors so direct, by independent legal counsel in a written opinion, or
(4) by the stockholders. To the extent that a present or former 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

                                       3
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 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) of the Delaware General
Corporation Law. The Registrant maintains directors and officers' liability
insurance.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

                  Not applicable.

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 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 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 any of the securities being
                  registered which remain unsold at the termination of the
                  offering.

                                       5
(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.

                  Pursuant to the requirements of the Securities Act of 1933,

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 Roseland, New Jersey, on the 30th day of August, 2006.
