      ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

      Section 102 of the General Corporation Law of the State of Delaware allows
a corporation to eliminate the personal liability of directors of a corporation
to the corporation or its stockholders for monetary damages for a breach of
fiduciary duty as a director, except where the director breached his duty of
loyalty, failed to act in good faith, engaged in intentional misconduct or
knowingly violated a law, authorized the payment of a dividend or approved a
stock repurchase in violation of Delaware corporate law or obtained an improper
personal benefit. The registrant has included such a provision in its Restated
Certificate of Incorporation.

      Section 145 of the General Corporation Law of the State of Delaware
provides that a corporation has the power to indemnify a director, officer,
employee or agent of the corporation and certain other persons serving at the
request of the corporation in related capacities against amounts paid and
expenses incurred in connection with an action or proceeding to which he or she
is or is threatened to be made a party by reason of such position, if such
person shall have 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 corporation, and,
in any criminal proceeding, if such person had no reasonable cause to believe
his conduct was unlawful; provided that, in the case of actions brought by or in
the right of the corporation, no indemnification shall be made with respect to
any matter as to which such person shall have been adjudged to be liable to the
corporation unless and only to the extent that the adjudicating court determines
that such indemnification is proper under the circumstances.

      Article Eighth of the Restated Certificate of Incorporation of the
registrant provides that a director or officer of the registrant will be
indemnified by the registrant to the fullest extent authorized by the General
Corporation Law of the State of Delaware against all expense, liability and loss
reasonably incurred or suffered by him or her, who we refer to as an indemnitee,
in connection with any action, suit or proceeding in which he or she is made a
party or is threatened to be made a party by reason of the fact that he or she
is or was a director, officer or employee of the registrant, whether the basis
of such proceeding is alleged action in an official capacity or in any other
capacity while serving as a director, officer, employee or agent. With respect
to proceedings to enforce rights to indemnification, the registrant will
indemnify indemnitees in connection with a proceeding initiated by him or her
only if the proceeding was authorized by the Board of Directors of the
registrant. The right to indemnification conferred is a contract right and
includes the right to be paid by the registrant the expenses incurred in
defending any such proceeding in advance of its final disposition.

      Article Eighth of the Restated Certificate of Incorporation of the
registrant further provides that if the General Corporation Law of the State of
Delaware is amended in the future to expand the indemnification permitted to
directors, the registrant must indemnify those persons to the fullest extent
permitted by such law. Article Eighth also provides that any repeal or
modification of Article Eighth may not increase the personal liability of any
director of the registrant for any act or occurrence taking place prior to that
time.

      Article V of the Amended and Restated By-Laws of the registrant provides
with respect to a third party action that the registrant will indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal,

                                      -2-


administrative or investigative by reason of the fact that he or she
is or was a director or officer of the registrant, or, while a director or
officer of the registrant, is or was serving at the request of the registrant as
a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses, including attorney's
fees, judgments, fines and amounts paid in settlement actually and reasonably
incurred by him or her in connection with such action, suit or proceeding.
Article V further provides with respect to derivative actions that the
registrant will indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action or suit by or in
the right of the registrant to procure a judgment in its favor by reason of the
fact that he or she is or was a director, officer, employee or agent of the
registrant, or, while a director or officer of the registrant, is or was serving
at the request of the registrant as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses, including attorney's fees, actually and reasonably incurred by
him or her in connection with the defense or settlement of such action or suit.

      Article V of the Amended and Restated By-Laws of the registrant further
provides that the registrant will advance all expenses incurred by the
indemnitee in defending any action, suit or proceeding in advance of its final
disposition within 20 days of a written request by the indemnitee. To the extent
required by law, such payments shall be made only upon receipt of a written
undertaking by the indemnitee that the indemnitee will repay such amounts if it
is ultimately determined that he or she is not entitled to be indemnified.

      Article V of the Amended and Restated By-Laws of the registrant is not
exclusive of any other rights to which those seeking indemnification may be
entitled under any by-law, agreement, vote of stockholders or disinterested
directors or otherwise. The indemnification continues after a person has ceased
to be a director, officer, employee or agent. The registrant may also indemnify
any person who is or was a director, officer, employee or agent of a corporation
absorbed in a consolidation or merger with the registrant in the same manner as
it may indemnify any person who is or was a director, officer, employee or agent
of the registrant.

      The registrant has entered into indemnification agreements with each of
its current non-employee directors to give such directors additional contractual
assurances regarding the indemnification provisions set forth in its certificate
of incorporation and bylaws and to provide additional procedural protections.

      The registrant has purchased directors' and officers' liability insurance
which would indemnify its directors and officers against damages arising out of
certain kinds of claims which might be made against them based on their
negligent acts or omissions while acting in their capacity as such.

      ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

      Not applicable.

      ITEM 8. EXHIBITS.

      The Exhibit Index immediately preceding the exhibits is incorporated
herein by reference.

      ITEM 9. UNDERTAKINGS.

      1. Item 512(a) of Regulation S-K. 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:

                                      -3-


                  (i) To include any prospectus required by Section 10(a)(3) of
      the Securities Act;

                  (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; and

                  (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 (i) and (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 with or furnished to the
      Commission by the registrant pursuant to Section 13 or Section 15(d) of
      the Exchange Act that are incorporated by reference in the 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
      the termination of the offering.

      2. Item 512(b) of Regulation S-K. The undersigned registrant hereby
undertakes that, for purposes 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 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.

      3. Item 512(h) of Regulation S-K. Insofar as indemnification for
liabilities arising under the Securities Act 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 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 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
Securities Act and will be governed by the final adjudication of such issue.

                                      -4-
