Board of Directors or Committee may decrease the number of shares of the
Preferred Stock designated for any existing class or series by a resolution

Directors or Committee at any time and from time to time out of any funds of the
Corporation legally available therefor.

   7
                  (c) In the event of any voluntary or involuntary liquidation,
dissolution, or winding-up of the Corporation, after distribution in full of the
preferential amounts, if any, to be distributed to the holders of shares of the
Preferred Stock or any series thereof, the holders of shares of the Common Stock
shall be entitled to receive all of the remaining assets of the Corporation
available for distribution to its stockholders, ratably in proportion to the
number of shares of the Common Stock held by them. A liquidation, dissolution,
or winding-up of the Corporation, as such terms are used in this paragraph (c),
shall not be deemed to be occasioned by or to include any consolidation or
merger of the Corporation with or into any other corporation or corporations or
other entity or a sale, lease, exchange, or conveyance of all or a part of the
assets of the Corporation.

            3.    General

expressly authorized to fix the same in its absolute and uncontrolled discretion
subject to the foregoing conditions. Shares so issued for which the
consideration shall have been paid or delivered to the Corporation shall be
deemed fully paid stock and shall not be liable to any further call or
assessment thereon, and the holders of such shares shall not be liable for any
further payments in respect of such shares.

                  (b) The Corporation shall have authority to create and issue
rights and options entitling their holders to purchase shares of the
Corporation's capital stock of any class or series or other securities of the
Corporation, and such rights and options shall be evidenced by instrument(s)
approved by the Board of Directors or Committee. The Board of Directors or
Committee shall be empowered to set the exercise price, duration, times for
exercise, and other terms of such options or rights; provided, however, that the
consideration to be received for any shares of capital stock subject thereto
shall not be less than the par value thereof.

            B.    The holders of capital stock of the Corporation shall not have
preemptive rights to acquire additional, unissued, or treasury shares of the
Corporation, or securities of the Corporation convertible into or carrying a
right to subscribe to or acquire shares.

            C.    Cumulative voting shall not be allowed in the election of
directors or for any other purpose.

less than the par value thereof), either in money or money's worth of property
or services, and for such other consideration, whether greater or less, now or
from time to time hereafter permitted by law, as may be fixed by the Board of
Directors; and all shares so issued shall be fully paid and nonassessable.

      No holder of any shares of any class shall as such holder have any
preemptive right to subscribe for or purchase any other shares or securities of
any class, whether now or hereafter authorized, which at any time may be offered
for sale or sold by the Corporation.

stockholders herein are granted subject to this reservation.

      THIRTEENTH: No director of the Corporation shall be liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or that involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the Delaware General Corporation
Law, or (iv) for any transaction from which the director derived an improper
personal benefit. If the Delaware General Corporation Law hereafter is amended
to authorize the further elimination or limitation of the liability of
directors, then the liability of a director of the Corporation, in addition to
the limitation on personal liability provided herein, shall be limited to the
fullest extent permitted by the amended Delaware General Corporation Law. Any
repeal or modification of this Section by the stockholders of the Corporation
shall be prospective only and shall not adversely affect any limitation on the
personal liability of a director of the Corporation existing at the time of such
repeal or modification.
