    administrative or investigative (other than an action by or in the right of

Item 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS
Subsection (a) of Section 145 of the General Corporation Law of the State
    of Delaware (the "DGCL") empowers a corporation to indemnify any
    person who was or 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 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,
    partnership, joint venture, trust or other enterprise, against expenses (including
    attorneys' fees), judgments, fines and amounts paid in settlement actually
    and reasonably incurred by him 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.
Subsection (b) of Section 145 of the DGCL empowers a corporation to indemnify
    any person who was or is a party or is threatened to be made a party to any
    threatened, pending or completed action, or suit by or in the right of the
    corporation to procure a judgment in its favor by reason of the fact that
    such person acted in any of the capacities set forth above, against expenses
    (including attorneys' fees) actually and reasonably incurred by him
    in connection with the defense or settlement of such action or suit if he
    acted in good faith and in a manner that he reasonably believed to be in or
    not opposed to the best interests of the corporation, except that no indemnification
    may be made in respect of any claim, issue or matter as to which such person
    shall have been made to be liable to the corporation unless and only to the
    extent that the Court of Chancery or the court in which such action or suit
    was brought shall determine upon application that, despite the adjudication
    of liability but in view of all of the circumstances of the case, such person
    is fairly and reasonably entitled to indemnity for such expenses which the
    Court of Chancery or such other court shall deem proper.
Section 145 of the DGCL further provides that to the extent a director or
    officer of a corporation has been successful on the merits or otherwise in
    the defense of any action, suit or proceeding referred to in subsections (a)
    and (b) of Section 145 in the defense of any claim, issue or matter therein,
    he shall be indemnified against expenses (including attorneys' fees)
    actually and reasonably incurred by him in connection therewith; that indemnification
    provided for by Section 145 shall not be deemed exclusive of any other rights
    to which the indemnified party may be entitled; that indemnification provided
    for by Section 145 shall, unless otherwise provided when authorized or ratified,
    continue as to a person who has ceased to be a director, officer, employee
    or agent and shall inure to the benefit of such person's heirs, executors
    and administrators; and empowers the corporation to purchase and maintain
    insurance on behalf of a director or officer of the corporation against any
    liability asserted against him and incurred by him in any such capacity, or
    arising out of his status as such whether or not the corporation would have
    the power to indemnify him against such liabilities under Section 145.
The Company's restated certificate of incorporation, as amended, provides
    for indemnification of directors and officers of the Company to the fullest
    extent permitted by applicable law. The Company's bylaws, as amended,
    also provide that directors and officers shall be indemnified against liabilities
    arising from their service as directors or officers to the fullest extent
    permitted by law, which generally requires that the individual act in good
    faith and in a manner he or she reasonably believes to be in or not opposed
    to the Company's best interests.
-3-
Section
    102(b)(7) of the DGCL provides that a certificate of incorporation may contain
    a provision eliminating or limiting the personal liability of a director to
    the corporation or its stockholders for monetary damages for breach of fiduciary
    duty as a director provided that such provision shall not eliminate or limit
    the liability of a director (i) for any breach of the director's duty
    of loyalty to the corporation or its 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.
In accordance with Section 102(b)(7) of the DGCL, the Company's restated
    certificate of incorporation, as amended, contains a provision that generally
    eliminates the personal liability of directors for monetary damages for breaches
    of their fiduciary duty, subject to limitations of Section 102(b)(7).
The Company maintains insurance policies that provide coverages to its directors
    and officers against certain liabilities.
Insofar as indemnification for liabilities arising under the Securities Act
    of 1933 may be permitted to directors, officers or persons controlling the
    registrants pursuant to the foregoing provisions, the registrants have been
    informed 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.

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% 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.
-5-
Provided,
    however,
that paragraphs (a)(1)(i) and (a)(1)(ii) of this section 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.
(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 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 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 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.
