board of directors, or in the event such meeting is not held at the time and
place so fixed by the stockholders, the meeting may be held at such time and

thereto in writing, and the writing or writings are filed with the minutes of
proceedings of the board or committee.

      Section 10. Unless otherwise restricted by the certificate of
incorporation or these by-laws, members of the board of  directors, or any

of directors, shall have and may exercise all the powers and authority of the
board of directors in the management of the business and affairs of the

as provided in Section 151(a) fix any of the preferences or rights of such
shares relating to dividends, redemption, dissolution, any distribution of
assets of the corporation or the conversion into, or the exchange of such shares
