Item 4.   Description of Securities.

          Not Applicable.

Item 5.   Interests of Named Experts and Counsel

          Not Applicable.

Item 6.   Indemnification of Directors and Officers

     Sections 145(a) and 145(b) of the Delaware General Corporation Law permit
a corporation to indemnify any person against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement or actually and
reasonably incurred by such person in connection with any threatened, pending or
completed non-derivative action and against expenses (including attorneys' fees)
actually and reasonably incurred in connection with any threatened, pending or
completed derivative action if such person was or is a party or was threatened
to be made a party to such action by reason of the fact that such person is or
was a director, officer, employee or agent of the corporation.  Any
indemnification shall be made if a determination in each instance is made either
by a majority vote of the Board of Directors (other than directors who are
parties to such action), by the stockholders, or by independent legal counsel,
that such indemnification is proper because the director, officer, employee or
agent acted in good faith and in a manner that such person reasonably believed
to be in or not opposed to the best interests of the corporation, and, with
respect to any criminal action or proceeding, that such person had no reasonable
cause to believe that his or her conduct was unlawful.  However, no
indemnification may be made with respect to a derivative action if such person
is adjudged to be liable to the corporation, unless and only to the extent that
the Delaware Court of Chancery or the court in which the action was brought
determines upon application that, despite the adjudication of liability but in
view of all the circumstances, such person is fairly and reasonably entitled to
indemnity for such expenses as the court deems proper.  To the extent that a
person has been successful in defense of any action, suit or proceeding, Section
145(c) provides that such person shall be indemnified against expenses actually
and reasonably incurred by him or her in connection therewith.  A corporation
may also advance expenses incurred in defending proceedings against an officer
or a director upon receipt of an undertaking by or on behalf of such officer or
director to repay such expenses to the corporation if it is ultimately
determined that such officer or director is not entitled to be indemnified for
such expenses.  The indemnification and advancement of expenses provided under
the Delaware General Corporation Law are not exclusive of any other rights to
indemnification or advancement of expenses a person may be entitled to under any
bylaw, agreement, vote of stockholders or disinterested directors or otherwise.

     Under the terms of Article Eleven of the Registrant's Certificate of
Incorporation, as amended, and Article XII of the Registrant's Bylaws, as
amended, the Registrant shall indemnify any person who is or was a director,
officer, employee or agent of the Registrant (or is or was

                                       3
<PAGE>

serving at the request of the Registrant as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise) in the manner and to the fullest extent permitted under Section 145
of the Delaware General Corporation Law against expenses, liabilities, and other
matters covered by or referred to in such Section 145.

     As permitted by paragraph (7) of subsection (b) of Section 102 of the
Delaware General Corporation Law, Article XII of the Registrant's Certificate of
Incorporation, as amended, provides that no director of the Registrant shall be
liable to the Registrant or its stockholders for monetary damages for breach of
his or her fiduciary duty as a director except for liability (a) for breach of
the director's duty of loyalty to the corporation or its stockholders; (b) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law; (c) under Section 174 of the Delaware General
Corporation Law (relating to unlawful declarations or payments of dividends or
unlawful stock purchases or redemptions); or (d) for any transaction from which
the director derived an improper personal benefit.

Item 7.   Exemption from Registration Claimed

          Not applicable.

Item 8.   Exhibits

          See Exhibit Index.

Item 9.   Undertakings

     (a)  The Registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
     made of the securities registered hereby, a post-effective amendment to
     this Registrant Statement to:

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

               (ii)   Reflect in the prospectus any facts or events which,
          individually or together, represent a fundamental change in the
          information in this Registration Statement;

               (iii)  Include any additional or changed material information on
          the plan of distribution;

provided, however, that the undertakings set forth in paragraphs (1)(i) and
--------  -------
(1)(ii) above do not apply if 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

                                       4
<PAGE>

Section 15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement.

          (2)  For determining 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
     end of the offering.

     (b)  The Registrant hereby further 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.

     (c)  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 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, unless in the opinion of its counsel the matter has
been settled by controlling precedent, will 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.

Item 4.   Description of Securities.

          Not Applicable.

Item 5.   Interests of Named Experts and Counsel

          Not Applicable.

Item 6.   Indemnification of Directors and Officers

     Sections 145(a) and 145(b) of the Delaware General Corporation Law permit
a corporation to indemnify any person against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement or actually and
reasonably incurred by such person in connection with any threatened, pending or
completed non-derivative action and against expenses (including attorneys' fees)
actually and reasonably incurred in connection with any threatened, pending or
completed derivative action if such person was or is a party or was threatened
to be made a party to such action by reason of the fact that such person is or
was a director, officer, employee or agent of the corporation.  Any
indemnification shall be made if a determination in each instance is made either
by a majority vote of the Board of Directors (other than directors who are
parties to such action), by the stockholders, or by independent legal counsel,
that such indemnification is proper because the director, officer, employee or
agent acted in good faith and in a manner that such person reasonably believed
to be in or not opposed to the best interests of the corporation, and, with
respect to any criminal action or proceeding, that such person had no reasonable
cause to believe that his or her conduct was unlawful.  However, no
indemnification may be made with respect to a derivative action if such person
is adjudged to be liable to the corporation, unless and only to the extent that
the Delaware Court of Chancery or the court in which the action was brought
determines upon application that, despite the adjudication of liability but in
view of all the circumstances, such person is fairly and reasonably entitled to
indemnity for such expenses as the court deems proper.  To the extent that a
person has been successful in defense of any action, suit or proceeding, Section
145(c) provides that such person shall be indemnified against expenses actually
and reasonably incurred by him or her in connection therewith.  A corporation
may also advance expenses incurred in defending proceedings against an officer
or a director upon receipt of an undertaking by or on behalf of such officer or
director to repay such expenses to the corporation if it is ultimately
determined that such officer or director is not entitled to be indemnified for
such expenses.  The indemnification and advancement of expenses provided under
the Delaware General Corporation Law are not exclusive of any other rights to
indemnification or advancement of expenses a person may be entitled to under any
bylaw, agreement, vote of stockholders or disinterested directors or otherwise.

     Under the terms of Article Eleven of the Registrant's Certificate of
Incorporation, as amended, and Article XII of the Registrant's Bylaws, as
amended, the Registrant shall indemnify any person who is or was a director,
officer, employee or agent of the Registrant (or is or was

                                       3
serving at the request of the Registrant as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise) in the manner and to the fullest extent permitted under Section 145
of the Delaware General Corporation Law against expenses, liabilities, and other
matters covered by or referred to in such Section 145.

     As permitted by paragraph (7) of subsection (b) of Section 102 of the
Delaware General Corporation Law, Article XII of the Registrant's Certificate of
Incorporation, as amended, provides that no director of the Registrant shall be
liable to the Registrant or its stockholders for monetary damages for breach of
his or her fiduciary duty as a director except for liability (a) for breach of
the director's duty of loyalty to the corporation or its stockholders; (b) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law; (c) under Section 174 of the Delaware General
Corporation Law (relating to unlawful declarations or payments of dividends or
unlawful stock purchases or redemptions); or (d) for any transaction from which
the director derived an improper personal benefit.

Item 7.   Exemption from Registration Claimed

          Not applicable.

Item 8.   Exhibits

          See Exhibit Index.

Item 9.   Undertakings

     (a)  The Registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
     made of the securities registered hereby, a post-effective amendment to
     this Registrant Statement to:

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

               (ii)   Reflect in the prospectus any facts or events which,
          individually or together, represent a fundamental change in the
          information in this Registration Statement;

               (iii)  Include any additional or changed material information on
          the plan of distribution;

provided, however, that the undertakings set forth in paragraphs (1)(i) and
--------  -------
(1)(ii) above do not apply if 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

                                       4
Section 15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement.

          (2)  For determining 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
     end of the offering.

     (b)  The Registrant hereby further 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.

     (c)  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 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, unless in the opinion of its counsel the matter has
been settled by controlling precedent, will 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.

                                       5
