Item 4. Description of Securities.

     Not applicable.

Item 5. Interests of Named Experts and Counsel.

     Not applicable.

Item 6. Indemnification of Directors and Officers.

     Section 145 of the Delaware General Corporation Law ("DGCL"), paragraph B
of Article SIXTH of the Company's Amended and Restated Certificate of
Incorporation and paragraph 5 of Article VII of the Company's By-laws provide
for the indemnification of the Company's directors and officers in a variety of
circumstances, which may include liabilities under the Securities Act of 1933,
as amended (the "Securities Act").

     Paragraph B of Article SIXTH of the Amended and Restated Certificate of
Incorporation, as amended, provides mandatory indemnification rights to any
officer or director of the Company who, by reason of the fact that he or she is
an officer or director of the Company, is involved in a legal proceeding of any
nature. Such indemnification rights shall include reimbursement for expenses
incurred by such officer or director in advance of the final disposition of such
proceeding in accordance with the applicable provisions of the DGCL. Paragraph 5
of Article VII of the Company's Amended and Restated By-laws currently provides
that the Company shall indemnify its directors and officers to the fullest
extent allowed by law.

     Paragraph A of Article SIXTH of the Amended and Restated Certificate of
Incorporation, as amended, contains a provision which eliminates the personal
liability of a director to the Company and its stockholders for certain breaches
of his or her fiduciary duty of care as a director. This provision does not,
however, eliminate or limit the personal liability of a director (i) for any
breach of such director's duty of loyalty to the Company 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 the Delaware statutory
provision making directors personally liable, under a negligence standard, for
unlawful dividends or unlawful stock repurchases or redemptions, or (iv) for any
transaction from which the director derived an improper personal benefit. This
provision offers persons who serve on the Board of Directors of the Company
protection against awards of monetary damages resulting from negligent (except
as indicated above) and "grossly" negligent actions taken in the performance of
their duty of care, including grossly negligent business decisions made in
connection with takeover proposals for the Company. As a result of this
provision, the ability of the Company or a stockholder thereof to successfully
prosecute an action against a director for a breach of his duty of care has been
limited. However, the provision does not affect the availability of equitable
remedies such as an injunction or rescission based upon a director's breach of
his duty of care.

     The Company maintains a directors' and officers' insurance policy which
insures the officers and directors of the Company from any claim arising out of
an alleged wrongful act by such persons in their respective capacities as
officers and directors of the Company. In addition, the Company has entered into
indemnification agreements with its officers and directors containing provisions
which are in some respects broader than the specific indemnification provisions
contained in the DGCL. The indemnification agreements require the Company, among
other things, to indemnify such officers and

                                      II-2

directors against certain liabilities that may arise by reason of their status
or service as directors or officers (other than liabilities arising from willful
misconduct of a culpable nature) and to advance their expenses incurred as a
result of any proceeding against them as to which they could be indemnified. The
Company believes that these agreements are necessary to attract and retain
qualified persons as directors and officers.

     It is currently unclear as a matter of law what impact these provisions
will have regarding securities law violations. The Commission takes the position
that indemnification of directors, officers and controlling persons against
liabilities arising under the Securities Act is against public policy as
expressed in the Securities Act and therefore is unenforceable.

     Not applicable.

Item 9. Undertakings.

     1.   The undersigned registrant hereby undertakes:

          (a) 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, as amended (the "Securities
                    Act");

               (ii) To reflect in the prospectus any facts or events arising
                    after the effective date of this Registration Statement (or
                    the most recent post-effective amendment hereof) which,
                    individually or in the aggregate, represent a fundamental
                    change in the information set forth in this Registration
                    Statement; and

               (iii) To include any material information with respect to the
                    plan of distribution not previously disclosed in this
                    Registration Statement or any material change to such
                    information in this Registration Statement;

provided, however, that paragraphs (1)(a)(i) and (1)(a)(ii) will not apply if
the information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the

                                      II-3

registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in this Registration Statement.

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

          (c) 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.

     2. The undersigned registrant hereby further undertakes that, for purposes
of determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in this 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.

     3. Insofar as 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 described under Item 6 above, 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 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 Securities Act and will be governed by the final
adjudication of such issue.

                                      II-4
