and the  Company's  Quarterly  Report on Form 10-Q for the fiscal  quarter ended

documents  subsequently filed by the Company pursuant to Sections 13(a),  13(c),
14 and 15(d) of the  Securities  Exchange Act of 1934,  prior to the filing of a
post-effective  amendment which indicates that all securities  offered have been
sold or which deregisters all securities then remaining unsold,  shall be deemed
to be incorporated by reference in the  Registration  Statement and to be a part
hereof from the date of filing of such documents.

Statement is the  Company's  common  stock,  par value $.01 per share,  which is

including any subsequent amendments or reports filed for the purpose of updating
such description.

Item 4. Description of Securities

are entitled to  indemnification as provided in the Certificate of Incorporation

permitted under the Delaware General Corporation Law. These provisions are broad

                                       3


Item 9. Undertakings

     The undersigned Registrant hereby undertakes:

          (1) 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.

          (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.

     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.

     The  undersigned  Registrant  hereby  undertakes  that  prior to any public
reoffering  of  the  securities  registered  hereunder  through  the  use  of  a
prospectus  which is a part of this  Registration  Statement,  by any  person or
party who is deemed to be an underwriter  within the meaning of Rule 145(c), the
issuer  undertakes that such reoffering  prospectus will contain the information
called for by the  applicable  registration  form with respect to reofferings by
persons who may be deemed  underwriters,  in addition to the information  called
for by the other items of the applicable form.

     The Registrant  undertakes that every prospectus (i) that is filed pursuant
to the  paragraph  immediately  preceding,  or (ii)  that  purports  to meet the
requirements  of  section  10(a)3 of the  Securities  Act of 1933 and is used in
connection with an offering of securities  subject to Rule 415, will be filed as
a part of an amendment to the Registration  Statement and will not be used until
such amendment is effective, and that, for purposes 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.

     In the event that an appendix is utilized by the undersigned  Registrant to
update information in the prospectus,  the undersigned issuer hereby undertakes:
(a) to provide  individuals  who have already  received copies of the prospectus
with  a copy  of any  such  current  appendix,  (b)  to  furnish  an  additional
prospectus, upon request, to anyone who has misplaced or discarded the old copy,
(c) to  supply  new  participants  in the plan with  both the  prospectus  and a
current appendix,  and (d) to file copies of such appendices with the Commission
in accordance with Rule 424(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.
