Item 4.  Description of Securities.

      The securities to be offered are registered under Section 12(b) of the
Exchange Act.

Item 5.  Interests of Named Experts and Counsel.

      Not applicable.

Item 6.  Indemnification of Directors and Officers.

      Article IV of the registrant's By-Laws states that the registrant shall
indemnify and hold harmless its directors and officers to the fullest extent
permitted by the laws of the State of Delaware. The registrant has also
entered into an indemnification agreement with each of its directors and
executive officers. Such agreement provides that the registrant shall
indemnify, and advance expenses, to the indemnified person to the fullest
extent permitted by applicable law in effect on the date of such agreement
and to such greater extent as thereafter permitted by law. The agreement is
governed by Delaware law. Such rights to indemnification and expense
advancement are provided when the indemnified person is, or is threatened to
be made, a party to certain proceedings or is a witness in such proceedings
because of his or her role as a director or officer of the registrant. The
indemnification agreement remains in effect for 10 years after the
indemnified person ceases to be an officer or director of the registrant, or
until final termination of all proceedings in which he or she is protected
under the agreement, whichever is later.

      Section 145 of the Delaware Corporation Law provides, in general, for
the indemnification of any director or officer who was, is, or is threatened
to be made a party in any action, suit or proceeding (other than an action by
or in the right of the registrant). In general, each director and officer is
indemnified against losses by reason of his or her being an officer or
director of the registrant provided that he or she acted in good faith and in
a manner 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 that his or her conduct was
unlawful. The directors and officers of the registrant are covered by a
policy of insurance under which they are insured, within limits and subject
to certain limitations, against certain expenses in connection with the
defense of actions, suits or proceedings, and certain liabilities which might
be imposed as a result of such actions, suits or proceedings, in which they
are parties by reason of being or having been directors or officers,
including actions, suits or proceedings arising out of any actual or alleged
error, misstatement, misleading statement, act or omission, or neglect or
breach of duty. The registrant is similarly insured, under such policy, with
respect to certain payments it might be required to make to its directors or
officers in accordance with applicable law and its By-law provisions relating
to indemnification.

      Section 102(b)(7) of the Delaware General Corporation Law permits a
corporation to provide in its certificate of incorporation that a director of
the corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duties as a
director, except for liability (i) for any breach of a director's duty of
loyalty to the corporation or its stockholders, (ii) for acts or omissions
not in good faith or that involve intentional misconduct or a knowing
violation of law, (iii) for improper payment of dividends, stock purchases or
redemptions of shares, or (iv) for any transaction from which the director
derives an improper personal benefit. The registrant's Restated Certificate
of Incorporation includes such a provision.


                                      4





Item 7.  Exemption from Registration Claimed.

      Not applicable.

Item 8.  Exhibits.

      The Exhibits required by Item 601 of Regulation S-K are filed as
Exhibits to this registration statement and indexed at page 10 of this
registration statement.

      The Registrant hereby undertakes that it has or will submit the Plan
and any amendment thereto to the Internal Revenue Service in a timely manner
for its determination that the Plan is qualified under Section 401 of the
Internal Revenue Code and has or will make all changes required by the
Internal Revenue Service in order to so qualify the Plan.

Item 9.  Undertakings.

      (a)  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 the 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 the registration statement. Notwithstanding the foregoing, any
      increase or decrease in volume of securities offered (if the total
      dollar value of securities offered would not exceed that which was
      registered) and any deviation from the low or high end of the estimated
      maximum offering range may be reflected in the form of prospectus filed
      with the Securities and Exchange Commission pursuant to Rule 424(b)
      under the Securities Act of 1933 if, in the aggregate, the changes in
      volume and price represent no more than a 20% change in the maximum
      aggregate offering price set forth in the "Calculation of Registration
      Fee" table in the effective registration statement.

      (iii)  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;

      provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
      apply if the registration statement is on Form S-3, Form S-8 or Form F-
      3, and the information required to be included in a post-effective
      amendment by those paragraphs is contained in periodic reports filed
      with or furnished to the Commission by the registrant pursuant to
      section 13 or section 15(d) of the Securities Exchange Act of 1934 that
      are incorporated by reference 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


                                      5





registered which remain unsold at the termination of the offering.

      (b)  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
the 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.

      (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.
