position or undertaken such service when such person is not a party to such
action, suit or proceeding.

ordered by a court, any indemnification under Sections 1 and 2 of this Article

standard of conduct set forth in Sections 1 and 2 of this Article. Such a
determination shall be made (a) by the Board of Directors by a majority vote of

domestic corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise against any liability asserted against such person and
incurred by him or her in any such capacity, or arising out of his or her 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.

the corporation. Any indemnification under this Article with regard to any
employee benefit plan shall apply notwithstanding any provisions of any employee
benefit plan. The corporation shall include any domestic or foreign predecessor
entity of the corporation in a merger or other transaction in which the
predecessor's existence ceased upon consummation of the transaction.

entitled to notice of or to vote at a meeting of stockholders shall be at the
close of business on the day next preceding the day on which notice is given,
or, if notice is waived, at the close of business on the day next preceding the
day on which the meeting is held. A determination of stockholders of record
entitled to notice of or to vote at a meeting of stockholders shall apply to any
adjournment of the meeting; providing, however, that the board of directors may
fix a new record date for the adjourned meeting.

         Section 5.    In order that the corporation may determine the
stockholders entitled to consent to corporate action in writing without a
meeting, the board of directors may fix a record date, which record date shall
not precede the date upon which the resolution fixing the record date is adopted
by the board of directors, and which date shall not be more than ten days after
the date upon which the resolution fixing the record date is adopted by the
board of directors. If no record date has been fixed by the board or directors,
the record date for determining stockholders entitled to consent to corporate
action in writing without a meeting, when no prior action by the board of
directors is required by this Article, shall be the first date on which a signed
written consent setting forth the action taken or proposed to be taken is
delivered to the corporation by delivery to its registered office in Delaware,
its principal place of business, or an officer or agent of the corporation
having custody of the book in which proceedings of meetings of stockholders are
recorded. Delivery made to a corporation's registered office shall be by hand or
by certified or registered mail, return receipt requested. If no record date has
been fixed by the board of directors and prior action by the board of directors
is required by this Article, the record date for determining stockholders
entitled to consent to corporate action in writing without a meeting shall be at
the close of business on the day on which the board of directors adopts the
resolution taking such prior action.

         Section 6.    In order that the corporation may determine the
stockholders entitled to receive payment of any dividend or other distribution
or allotment of any rights or the stockholders entitled to exercise any rights
in respect of any change, conversion or exchange of stock or for the purpose of
any other lawful action, the board of directors may fix a record date, which
record date shall not precede the date upon which the resolution fixing the
record date is adopted, and which record date shall be not more than sixty days
prior to such action. If no record date is fixed, the record date for
determining stockholders for any such purpose shall be at the close of business
on the day on which the board of directors adopts the resolution relating
thereto.

                             REGISTERED STOCKHOLDERS

         Section 7.    The corporation shall be entitled to recognize the
exclusive right of a person registered on its books as the owner of shares to
receive dividends, and to vote as such owner, and to hold liable for calls and
assessment a person registered on its books as the owner of shares, and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of any other person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                  shall be held annually, within four (4) months of the end of
                  each fiscal year of the corporation. The annual meeting shall

                  meeting of the shareholders and shall serve for a term of one
                  year and until their successors are elected. A majority of
