ITEM 4.  Description of Securities.

         Not Applicable.

ITEM 5.  Interests of Named Experts and Counsel.

         Not Applicable.

ITEM 6.  Indemnification of Directors and Officers.

         Section 145 of the Delaware General Corporation Law (the "DGCL")
provides that a Delaware corporation may indemnify its directors and officers
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement that are actually and reasonably incurred by such officers and
directors in connection with any action, suit or proceeding, whether civil,
criminal, administrative or investigative, if, in connection with the matters in
issue, they acted in good faith and in a manner they reasonably believed by them
to be in, or not opposed to, the best interests of the corporation, and, with
respect to any criminal suit or proceeding, they had no reasonable cause to
believe their conduct was unlawful. If the action is brought by or in the right
of the corporation, such indemnification may only be provided as long as, in
addition to the foregoing, it is not made with respect to any claim, issue or
matter as to which such officer or director has been found liable to the
corporation, unless such indemnification is approved by the court. Section 145
permits a Delaware corporation to grant its directors and officers additional
rights of indemnification through bylaw provisions and otherwise and to purchase
indemnity insurance on behalf of its directors and officers.

         Pursuant to Article Ninth of the Company's Restated Certificate of
Incorporation, a director of the Company will not be personally liable to the
Company or to its shareholders for monetary damages for any breach of fiduciary
duty by such director other than liability (i) for any breach of the director's
duty of loyalty, (ii) arising out of acts or omissions not taken in good faith
or which involve intentional misconduct or a knowing violation of the law, (iii)
under Section 174 of the DGCL (relating to the unlawful payments of dividends or
redemption of stock) or (iv) arising from a transaction from which the director
derived a personal benefit. In addition, such Article Ninth provides that the
Company may indemnify its officers and directors to the fullest extent
authorized by law, including indemnification under statutory or case law or
pursuant to indemnity agreements or contracts with such persons.

         As permitted by Section 3.16 of its Bylaws, the Company has entered
into Indemnification Agreements with each director and executive officer of the
Company which provide for indemnity on terms consistent with the foregoing.

         As permitted under Section 145 of the DGCL, the Company has purchased
and maintains insurance on behalf of directors and officers against any
liability asserted against such directors and officers in their capacities as
such.

ITEM 7.  Exemption from Registration Claimed.

         Not Applicable

ITEM 9.  Undertakings

         The undersigned Registrant hereby undertakes:

               (a)(l) To file, during any period in which offers or sales are
         being made, a post-effective amendment to this Registration Statement
         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 (the "Act"), each such post-effective amendment
         shall be deemed to be a new


                                       3


         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 a post-effective
         amendment any of the securities being registered which remain unsold at
         the termination of the offering.

               (b) That, for purposes of determining any liability under the
         Act, each filing of the Registrant's annual report pursuant to Section
         13(a) or 15(d) of the Securities Exchange Act of 1934 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.

               (h) That, insofar as indemnification for liabilities arising
         under the Act may be permitted to directors, officers and controlling
         persons of the Registrant as described in Item 6 hereof 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.
