application of any stockholder or stockholders holding at least ten percent of
the total number of the shares at the time outstanding having the right to vote
for such directors, summarily order an election to be held to fill any such
vacancies or newly created directorships, or to replace the directors chosen by
the directors then in office.

request of two directors unless the Board consists of only one director; in
which case special meetings shall be called by the President or Secretary in
like manner or on like notice on the written request of the sole director.

may adjourn the meeting from time to time, without notice other than

resolution passed by a majority of the whole Board, designate one or more
committees, each such committee to consist of one or more of the directors of
the corporation. The Board may designate one or more directors as alternate
members of any committee, who may replace any absent or disqualified member at
any meeting of the committee. In the absence or disqualification of a member of
a committee, the member or members thereof present at any attendance at each
meeting of the Board of Directors or a stated salary as director. No such
payment shall preclude any director from serving the corporation in and other
capacity and receiving compensation therefor. Members of special or standing
committees may be allowed like compensation for attending committee meetings.

                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

      (a) The corporation shall indemnify to the maximum extent permitted by law
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, administrative or investigative (other than an action by or in the
right of the corporation) by reason of the fact that he is or was a director or
officer of the corporation, or is or was serving at the request of the
corporation as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

      (b) The corporation shall indemnify to the maximum extent permitted by law
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
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director or officer of the corporation, or is or

<PAGE>

was serving at the request of the corporation as a director or officer of
another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection with the defense or settlement of such action or suit if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation and except that no such
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery of Delaware or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which such Court of Chancery or such other court shall deem proper.

      (c) To the extent that a present or former director or officer of the
corporation shall be successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in paragraphs (a) and (b), or in defense
of any claim, issue or matter therein, such person shall be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred by such
person in connection therewith.

      (d) Any indemnification under paragraphs (a) and (b) (unless ordered by a
court) shall be made by the corporation only as authorized in the specific case
upon a determination that indemnification of the present or former director or
officer is proper in the circumstances because he has met the applicable
standard of conduct set forth in paragraphs (a) and (b). Such determination
shall be made, with respect to a person who is a director or officer at the time
of such determination, (1) by a majority vote of the directors who are not
parties to such action, suit or proceeding, even though less than a quorum, or
(2) by a committee of such directors designated by majority vote of such
directors, even though less than a quorum, or (3) if there are no such
directors, or if such directors so direct, by independent legal counsel in a
written opinion, or (4) by the stockholders. The corporation, acting through its
Board of Directors or otherwise, shall cause such determination to be made if so
requested by any person who is indemnifiable under this Article V.

      (e) Expenses (including attorneys' fees) incurred by an officer or
director in defending any civil, criminal, administrative or investigative
action, suit or proceeding may be paid by the corporation in advance of the
final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that such person is not entitled to be
indemnified by the corporation as authorized in this Article V. Such expenses
(including attorneys' fees) incurred by former directors and officers may be so
paid upon such terms and conditions, if any, as the corporation deems
appropriate.

      (f) The indemnification and advancement of expenses provided by, or
granted pursuant to, the other paragraphs of this Article V shall not be deemed
exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in such
person's official capacity and as to action in another capacity while holding
such office.

<PAGE>

      (g) The Board of Directors may authorize, by a vote of a majority of a
quorum of the Board of Directors, the corporation to purchase and maintain
insurance on behalf of any person who is or was a director or officer of the
corporation, or is or was serving at the request of the corporation as a
director or officer of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against such person and incurred
by such person in any such capacity, or arising out of such person's status as
such, whether or not the corporation would have the power to indemnify such
person against such liability under the provisions of this Article V.

      (h) For the purposes of this Article V, references to "the corporation"
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors or officers so that any
person who is or was a director or officer of such constituent corporation, or
is or was serving at the request of such constituent corporation as a director
or officer of another corporation, partnership, joint Venture, trust or other
enterprise, shall stand in the same position under the provisions of this
Article V with respect to the resulting or surviving corporation as such person
would have with respect to such constituent corporation if its separate
existence had continued.

      (i) For purposes of this section, references to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the corporation" shall include service
as a director or officer of the corporation which imposes duties on, or involves
services by, such director or officer with respect to an employee benefit plan,
its participants or beneficiaries; and a person who acted in good faith and in a
manner such person reasonably believed to be in the interest of the participants
and beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner " not opposed to the best interests of the corporation" as referred to in
this section.

      (j) The indemnification and advancement of expenses provided by, or
granted pursuant to, this Article V shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a director
or officer and shall inure to the benefit of the heirs, executors and
administrators of such a person.

      (k) The corporation shall be required to indemnify a person in connection
with an action, suit or proceeding (or part thereof) initiated by such person
only if the action, suit or proceeding (or part thereof) was authorized by the
Board of Directors of the corporation.

                                   ARTICLE VI.

                     INDEMNIFICATION OF EMPLOYEES AND AGENTS

      The corporation may indemnify every person who was or is a party or is or
was threatened to be made a party to any action, suit, or proceeding, whether
civil, criminal, administrative or investigative, by reason of the fact that he
is or was an employee or agent of the corporation or, while an employee or agent
of the corporation, is or was serving at the request of the corporation as an
employee or agent or trustee of another corporation,

<PAGE>

partnership, joint venture, trust, employee benefit plan or other enterprise,

settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding, to the extent permitted by applicable law.

                                  ARTICLE VII.

before certificate is issued, it may be issued by the corporation with the same
effect as if he were such officer, transfer agent, or registrar at the date of
issue.

corporation shall be authorized to issue more than one class of stock or more
than one series of any class, the powers, designations, preferences and

                     INDEMNITY OF OFFICERS, DIRECTORS, ETC.

      Section 6. The Corporation shall indemnify any person who was or is a
party or its threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, except in an action by or in the right of the Corporation by
reason of the fact that he is or was a Director, officer, employee or agent of
the Corporation, or is or was serving at the request of the Corporation as a
Director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses including attorneys' fees,
judgments, fines and amounts paid in settlement actually and reasonably incurred
in connection with such action, suit or proceedings if he acted in good faith
and in a manner 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, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the Corporation and that, with respect to any criminal action or
proceeding, he had reasonable cause to believe that his conduct was unlawful.

      Section 7. The Corporation shall 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 Corporation to procure a
judgment in its favor by reason of the fact that he is or was a Director,
officer, employee, or agent of the Corporation, or is or was serving at the
request of the Corporation as a Director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses actually and reasonably incurred by him in connection with the defense
or settlement of such action or suit if he acted in good faith and in a manner
which he reasonably believed to be in or not opposed to the best interests of
the Corporation; except no indemnification shall be made by

the Corporation in respect of any claim, issue or matter as to which such person
has been adjudged to be liable for negligence or misconduct in the performance
of his duty to the Corporation unless and only to the extent that the court in
which such action or suit was brought determines upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnification for such
expenses as the court deems proper.

      Any indemnification under Section 6 or 7 of this Article, unless ordered
by a court, shall be made by the Corporation only as authorized in the specific
case upon a determination that indemnification of the Director, officer,
employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in Sections 6 and 7. Determination as
to such conduct shall be made:

      (1) By the stockholders; or

      (2) By the Board of Directors by majority vote of a quorum consisting of
Directors who were not parties to such act, suit or proceeding; or

      (3) If such a quorum of disinterested Directors so orders, by independent
legal counsel in a written opinion; or

      (4) If such a quorum of disinterested Directors cannot be obtained, by
independent legal counsel in a written opinion.

      A Director, officer, employee or agent of the Corporation who is seeking
indemnification shall make a written request for such indemnification to the
Board. Upon receipt of such request the Board shall act promptly and in
compliance with the procedure set forth above.

      Expenses incurred in defending any proceeding shall be advanced by the
Corporation prior to the final disposition of such proceeding upon receipt of an
undertaking by or on behalf of the Director, officer, employee or agent to repay
such amount unless it shall be determined ultimately that the agent is entitled
to be indemnified as authorized in this Section.

      Section 8. The Corporation shall indemnify any Director, officer, employee
or agent of the Corporation who has been successful on the merits or otherwise
in defense of any action, suit or proceeding referred to in this Section, or in
defense of any item, issue or matter therein, against expenses, including
attorneys' fees, actually and reasonably incurred by him in connection with such
defense.
