Item 6.  Indemnification of Directors and Officers

           Article VII of the Company's Bylaws, as amended, provides for
indemnification of officers, directors, agents and employees of the Company
generally consistent with the provisions of Section 145 of the Delaware General
Corporation Law. Pursuant to Section 145 of the Delaware General Corporation
Law, a corporation generally has the power to indemnify its present and former
directors, officers, employees and agents against expenses incurred by them in
connection with any suit to which they are, or are threatened to be made, a
party by reason of their serving in such positions so long as they acted in good
faith and in a manner they reasonably believed to be in, or not opposed to, the
best interests of the corporation, and with respect to any criminal action, they
had no reasonable cause to believe their conduct was unlawful. With respect to
suits by or in the right of a corporation, however, indemnification is not
available if such person is adjudged to be liable for negligence or misconduct
in the performance of his duty to the corporation unless the court determines
that indemnification is appropriate. In addition, a corporation has the power to
purchase and maintain insurance for such persons. The statute also expressly
provides that the power to indemnify authorized thereby is not exclusive of any
rights granted under any bylaw, agreement, vote of stockholders or disinterested
directors, or otherwise.

           As permitted by Section 102 of the Delaware General Corporation Law,
the Company's stockholders have approved and incorporated provisions into the
Company's Restated Certificate of Incorporation eliminating a director's
personal liability for monetary damages to the Company and the Company's
stockholders arising from a breach of a director's fiduciary duty, except for
liability under Section 174 of the Delaware General Corporation Law or liability
for any breach of the director's duty of loyalty to the Company or the Company's
stockholders, for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law or for any transaction in
which the director derived an improper personal benefit.

           The Company has entered into indemnification agreements with the
Company's directors and officers. These agreements provide broader indemnity
rights than those provided under the Delaware General Corporation Law and the
Company's Bylaws. The indemnification agreements are not intended to deny or
otherwise limit third party or derivative suits against the Company or the
Company's directors or officers, but to the extent a director or officer were
entitled to indemnity or contribution under the indemnification agreement, the
financial burden of a third party suit would be borne by the Company, and the
Company would not benefit from derivative recoveries against the director or
officer. Such recoveries would accrue to the benefit of the Company but would be
offset by the Company's obligations to the director or officer under the
indemnification agreement.

           The above discussion of the Company's Bylaws, Certificate of
Incorporation and of Section 145 of the Delaware General Corporation Law is not
intended to be exhaustive and is qualified in its entirety by such Bylaws,
Certificate of Incorporation, and statute.

Item 7.  Exemption from Registration Claimed.

           Not applicable.

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:

           (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 this 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 this
                      registration statement;

           (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)(i) and (1)(ii) do 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
        registrant pursuant to Section 13 or Section 15(d) of the Exchange Act
        that are incorporated by reference in this Registration Statement.

           (2) 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; and

           (3) To remove from registration by means of post-effective amendment
        any of the securities 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, 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.

           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 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 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.
