ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

        Section 102(b)(7) of the Delaware General Corporation Law permits a
Delaware corporation to limit the personal liability of its directors in
accordance with the provisions set forth therein. The Certificate of
Incorporation, as amended, of the Company provides that the personal liability
of its directors shall be limited to the fullest extent permitted by applicable
law.

        Section 145 of the Delaware General Corporation Law contains provisions
permitting corporations to indemnify any person who is or was a director,
officer, employee or agent of the corporation, or who 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, in
accordance with the provisions set forth therein. The Bylaws of the Company
generally provide for indemnification of such persons to the fullest extent
allowed by applicable law.

        The inclusion of the above provisions in the Certificate of
Incorporation may have the effect of reducing the likelihood of stockholder
derivative suits against directors and may discourage or deter stockholders or
management from bringing a lawsuit against directors for breach of their duty of
care, even though such an action, if successful, might otherwise have benefited
the Company and its stockholders.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED

        Not applicable.

ITEM 8. EXHIBITS

        See Index to Exhibits on page 6.

ITEM 9. UNDERTAKINGS

        (a)     The Company 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, 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 thereof) 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 (a)(1)(i) and (a)(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 Company 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.

                (3) To remove from registration by means of a post-effective
        amendment any of the securities being registered which remain unsold at
        termination of the offering.


                                       3


   4
        (b) The Company hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Company's annual report
pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
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.

        (c) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Company pursuant to the foregoing provisions, or otherwise, the Company
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 expenses incurred or paid by a
director, officer or controlling person of the Company 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
Company 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.
