      the outstanding common stock of the Registrant.

Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

The Registrant is incorporated under the laws of the State of Delaware.  Section
145 of the  General  Corporation  Law of the  State  of  Delaware  (the  "DGCL")
provides that a Delaware  corporation  may indemnify any persons who are, or are
threatened to be made,  parties 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 such corporation),  by reason of the
fact  that such  person  was an  officer,  director,  employee  or agent of such
corporation,  or is or was  serving at the request of such person as an officer,
director,  employee or agent of another corporation or enterprise. The indemnity
may include expenses (including attorneys' fees),  judgments,  fines and amounts
paid in settlement actually and reasonably incurred by such person in connection
with such action,  suit or  proceeding,  provided that such person acted in good
faith and in a manner he  reasonably  believed  to be in or not  opposed  to the
corporation's  best  interests  and,  with  respect  to any  criminal  action or
proceeding,  had no reasonable cause to believe that his conduct was illegal.  A
Delaware  corporation may indemnify any persons who are, or are threatened to be
made, a party to any  threatened,  pending or completed  action or suit by or in
the right of the  corporation  by reason  of the fact  that  such  person  was a
director,  officer, employee or agent of such corporation,  or is or was serving
at the request of such corporation as a director,  officer, employee or agent of
another corporation or enterprise. The indemnity may include expenses (including
attorneys'  fees) actually and reasonably  incurred by such person in connection
with the defense or settlement of such action or suit provided such person acted
in good faith and in a manner he reasonably  believed to be in or not opposed to
the  corporation's  best interests except that no  indemnification  is permitted
without judicial approval if the officer or director is adjudged to be liable to
the  corporation.  Where an officer or director is  successful  on the merits or
otherwise in the defense of any action referred to above,  the corporation  must
indemnify  him against the expenses  which such officer or director has actually
and reasonably  incurred.  The  Registrant's  certificate of  incorporation  and
bylaws  provide  for  the  indemnification  of  directors  and  officers  of the
Registrant to the fullest extent permitted by the DGCL.

The  Registrant's  Restated  Certificate  of  Incorporation   provides  for  the
indemnification  by the  Registrant  of its  directors  and officers to the full
extent  permitted by Section 145 of the General  Corporation Law of the State of
Delaware (or any similar  provision or provisions of applicable  law at the time
in effect).  This indemnification is not deemed exclusive of any other rights to
which  those  seeking   indemnification  might  be  entitled  under  any  bylaw,
agreement,  vote of shareholders or disinterested directors, or otherwise,  both
as to action in an official  capacity and as to action in another capacity while
holding such office.  This  indemnification  will continue as to such person who
was a director or officer



of the  Registrant,  but has ceased to be a director or officer and inure to the
benefit  of  the  heirs,  executors  and  administrators  of  such  person.  The
Registrant's  bylaws also provide that the Registrant  will indemnify any person
who was or is a party  or has  threatened  to be made a party to any  action  by
reason of the fact that he or she is or was a  director,  officer,  employee  or
agent of the Registrant or is or was serving at the request of the Registrant as
a director,  officer, employee or agent of another entity, if he or she acted in
good faith and in a manner  that he or she  reasonably  believed to be in or not
opposed  to the best  interests  of the  Registrant  and,  with  respect  to any
criminal  action or  proceeding,  had no reasonable  cause to believe his or her
conduct was unlawful.

The Restated Certificate of Incorporation of the Registrant limits the liability
of its directors to the corporation or its stockholders for any monetary damages
for breaches of fiduciary duty as a director.  Under the  Registrant's  Restated
Certificate of  Incorporation,  as amended,  and as permitted under the Delaware
General  Corporation  Law,  directors  are not liable to the  Registrant  or its
stockholders  for  monetary  damages  arising  from a breach of their  fiduciary
duties as directors.  Such provision,  however,  does not eliminate or limit the
liability of a director (i) for any breach of the director's  duty of loyalty to
the Registrant 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 Delaware General Corporation Law (relating to liability
of directors  for  unlawful  payment of dividend or unlawful  stock  purchase or
redemption);  or (iv) for any  transaction  from which the  director  derived an
improper personal  benefit.  The director's  limitations of liability  described
above  may not limit a  director's  liability  for  violation  of, or  otherwise
relieve the  Registrant or its directors  from the necessity of complying  with,
federal  or state  securities  laws or  affect  the  availability  of  equitable
remedies,  such as  injunctive  relief or  rescission.  However,  as a practical
matter, equitable remedies may not be available in all situations, and there may
be instances in which no effective remedy is available at all.

The  foregoing  summaries  are  necessarily  subject to the complete text of the
statutes,  the Restated  Certificate  of  Incorporation  and bylaws  referred to
above, and are qualified in their entirety by reference thereto.

Item 9. Undertakings.

The Registrant hereby undertakes:

      (a)   To file,  during any period in which  offers or sales are being made
            of the securities  registered hereby, 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 (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 the  undertakings  set forth in paragraphs
            (a)(i) and (a)(ii) above do not apply if the Registration  Statement
            is on Form  S-3 or  Form  S-8 and  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  Securities  Exchange Act of 1934
            (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  remaining  unsold  at the
            termination of the offering.

      (d)   That, for purpose 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  herein,  and the offering of such  securities  at that time
            shall be deemed to be the initial bona fide offering thereof.

      (e)   Insofar  as   indemnification   for  liabilities  rising  under  the
            Securities   Act  may  be  permitted  to  directors,   officers  and
            controlling  persons of the Registrant pursuant to the provisions of
            the  Restated   Certificate  of   Incorporation  or  Bylaws  of  the
            Registrant  and the  provisions of the laws of the State of Delaware
            described in Item 6, above,  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 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 expense
            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.

SIGNATURES
