         ITEM 4.           DESCRIPTION OF SECURITIES.

         Not applicable. (The common stock is registered under Section 12 of the
         Exchange Act.)

         ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

         ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Registrant is a Delaware corporation, subject to the provisions of
Delaware corporate law. Section 145 of the General Corporation Law of the State
of Delaware (the "Delaware Law") empowers a Delaware corporation to indemnify
any persons who are, or are threatened to be made, parties to any threatened,
pending or completed legal 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 is or was an officer or
director 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),
judgments, fines and amounts paid in settlement of such action, suit or
proceeding, provided that such officer or director acted in good faith and in a
manner he or she reasonably believed to be in or not opposed to the
corporation's best interest, and, for criminal proceedings, had no reasonable
cause to believe his or her conduct was illegal. A Delaware corporation may
indemnify officers and directors against expenses (including attorney's fees) in
connection with the defense or settlement of an action by or in the right of the
corporation under the same conditions, except that no indemnification is
permitted without judicial approval if the officer or director is adjudged to be
liable to the corporation.

         The certificate of incorporation of the Registrant contains a provision
to limit the personal liability of the directors of the Registrant for
violations of their fiduciary duty, except to the extent such limitation of
liability is prohibited by the Delaware Law. This provision eliminates each
director's liability to the Registrant or its stockholders for monetary damages
except (i) for any breach of the director's duty of loyalty to the Registrant or
its stockholders, (ii) for acts or omissions


                                     - 3 -
<PAGE>


not in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) under Section 174 of the Delaware Law providing for liability of
directors for unlawful payment of dividends or unlawful stock purchases or
redemptions, or (iv) for any transaction from which a director derived an
improper personal benefit. The Bylaws of the Registrant provide that the
Registrant will indemnify directors and officers to the fullest extent permitted
by law. The effect of these provisions is to eliminate the personal liability of
directors for monetary damages for actions involving a breach of their fiduciary
duty of care, including any such actions involving gross negligence.

         In addition, the Registrant has entered into indemnity agreements with
its executive officers and directors whereby the Registrant obligates itself to
indemnify such officers and directors from any amounts which the officer or
director becomes obligated to pay because of any claim made against such officer
or director arising out of any act or omission committed while such officer or
director is acting in the capacity of an officer or director of the Registrant.

         The Registrant maintains directors and officers liability insurance
coverage that insures its officers and directors against certain losses that may
arise out of their positions with the Registrant and insures the Registrant for
liabilities it may incur to indemnify its officers and directors.

         ITEM 9.           UNDERTAKINGS.

         (a)      The 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 (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 (a)(1)(i) and (a)(1)(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 this 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.

         (b) The 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 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.

         (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 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 for the payment by the
Registrant of expenses incurred or paid by a director,


                                     - 5 -
<PAGE>


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 of 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. (The common stock is registered under Section 12 of the
         Exchange Act.)

         ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

         ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Registrant is a Delaware corporation, subject to the provisions of
Delaware corporate law. Section 145 of the General Corporation Law of the State
of Delaware (the "Delaware Law") empowers a Delaware corporation to indemnify
any persons who are, or are threatened to be made, parties to any threatened,
pending or completed legal 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 is or was an officer or
director 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),
judgments, fines and amounts paid in settlement of such action, suit or
proceeding, provided that such officer or director acted in good faith and in a
manner he or she reasonably believed to be in or not opposed to the
corporation's best interest, and, for criminal proceedings, had no reasonable
cause to believe his or her conduct was illegal. A Delaware corporation may
indemnify officers and directors against expenses (including attorney's fees) in
connection with the defense or settlement of an action by or in the right of the
corporation under the same conditions, except that no indemnification is
permitted without judicial approval if the officer or director is adjudged to be
liable to the corporation.

         The certificate of incorporation of the Registrant contains a provision
to limit the personal liability of the directors of the Registrant for
violations of their fiduciary duty, except to the extent such limitation of
liability is prohibited by the Delaware Law. This provision eliminates each
director's liability to the Registrant or its stockholders for monetary damages
except (i) for any breach of the director's duty of loyalty to the Registrant or
its stockholders, (ii) for acts or omissions

                                     - 3 -
not in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) under Section 174 of the Delaware Law providing for liability of
directors for unlawful payment of dividends or unlawful stock purchases or
redemptions, or (iv) for any transaction from which a director derived an
improper personal benefit. The Bylaws of the Registrant provide that the
Registrant will indemnify directors and officers to the fullest extent permitted
by law. The effect of these provisions is to eliminate the personal liability of
directors for monetary damages for actions involving a breach of their fiduciary
duty of care, including any such actions involving gross negligence.

         In addition, the Registrant has entered into indemnity agreements with
its executive officers and directors whereby the Registrant obligates itself to
indemnify such officers and directors from any amounts which the officer or
director becomes obligated to pay because of any claim made against such officer
or director arising out of any act or omission committed while such officer or
director is acting in the capacity of an officer or director of the Registrant.

         The Registrant maintains directors and officers liability insurance
coverage that insures its officers and directors against certain losses that may
arise out of their positions with the Registrant and insures the Registrant for
liabilities it may incur to indemnify its officers and directors.

ITEM 9.           UNDERTAKINGS.

         (a)      The 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 (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 (a)(1)(i) and (a)(1)(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 this 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.

         (b) The 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 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.

         (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 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 for the payment by the
Registrant of expenses incurred or paid by a director,

                                     - 5 -
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 of 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.
