                                ----------------

Section 1. Right to Indemnification.
-------------------------------------  The Company shall indemnify to the extent
not prohibited by applicable  law, any person who was or is a party (which shall
include  for  purposes  of this  Article IV the giving of  testimony  or similar
involvement) or is threatened to be made a party to any  threatened,  pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative,  by  reason of the fact  that he is or was a  director,  officer,
employee  or agent of the  Company or is or was  serving  at the  request of the
Company  as a  director,  officer,  employee  or agent of  another  corporation,
partnership,  joint venture,  trust or other  enterprise,  including an employee
benefit plan, against any liability,  penalty, damages, excise tax assessed with
respect to an employee  benefit  plan,  costs,  expenses  (including  attorneys'

arises or arose from any threatened, pending or completed action by or in the
right of the Company. The board of directors may, and on request of any such
person shall be required to, determine in each case whether applicable law
prohibits indemnification, or such determination shall be made by independent
legal counsel if the board so directs or if the board is not empowered by law to
make such determination. If there has been a change in control (as such term is
used in Item 6(a) of Schedule 14A promulgated by the Securities and Exchange

between (1) the time of the action or failure to act giving rise to the claim
for indemnification and (2) the time such claim is made, at the option of the
person seeking indemnification the permissibility of indemnification shall be
determined by independent legal counsel selected jointly by the Company and the
person seeking indemnification. The fees and expenses of such counsel shall be
paid by the Company. The obligations of the Company to indemnify a director,
officer, employee or agent under this Article IV, including the duty to advance
expenses, shall be a contract between the Company and such person, and no
modification or repeal of any provision of this Article IV shall affect, to the
detriment of the director, officer, employee or agent such obligations of the
Company in connection with a claim based on any act or failure to act occurring
before such modification or repeal.

Section 2.  Advancement of Expenses.
------------------------------------ Expenses (including attorney's fees)
incurred in defending an action, suit or proceeding referred to in this Article
IV shall be paid by the Company in advance of the final disposition of such
action, suit or proceeding upon receipt of an undertaking by or on behalf of the
indemnified person to repay such amount if it shall ultimately be determined
that such person is not entitled to be indemnified by the Company as authorized
in this Article IV or otherwise.

Section 3.  Indemnification Not Exclusive.
------------------------------------------ The indemnification and advancement
of expenses provided by this Article IV shall not be deemed exclusive of any
other right to which one indemnified may be entitled under any agreement, vote
of shareholders or otherwise, both as to action in his official capacity and as
to action in another capacity while holding that office, and shall inure to the
benefit of the heirs, executors and administrators of any such person.

trustee, or otherwise secure in any manner any of its indemnification
obligations and (c) give other indemnification to the extent not prohibited by
applicable law.

the books of the Company only by the registered holder or by duly authorized
attorney. A transfer shall be made only upon surrender of the share certificate.
