as the board of directors of such corporation may determine.

        Shares held by an administrator, executor, guardian or conservator may
be voted by him, either in person or by proxy, without a transfer of such shares
into his name. Shares standing in the name of a trustee may be voted by him,
either in person or by proxy, but no trustee shall be entitled to vote shares
held by him without a transfer of such shares into his name.

        Shares standing in the name of a receiver may be voted by such receiver,
and shares held by or under the control of a receiver may be voted by such
receiver without the transfer thereof into his name if authority so to do be
contained in an appropriate order of the court by which such receiver was
appointed.

        A shareholder whose shares are pledged shall be entitled to vote such
shares until the shares have been transferred into the name of the pledgee, and
thereafter the pledgee shall be entitled to vote the shares so transferred.

        Shares of its own stock belonging to the corporation or held for its
benefit by another corporation in a fiduciary capacity or held by a corporation
in which the corporation holds a majority of the voting shares shall not be
voted at any meeting or counted in determining the total number of outstanding

five days previously thereto by written notice delivered personally or mailed to
each director at his business address, or by telegram. If mailed, such notice
shall be deemed to be delivered when deposited in the United States mail so
addressed, with postage thereon prepaid. If notice be given by telegram, such
notice shall be deemed to be delivered when the telegram is delivered to the
telegraph company. Any director may waive notice of any meeting. The attendance
of a director at a meeting shall constitute a waiver of notice of such meeting,
except where a director attends a meeting for the express purpose of objecting
to the transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the board of directors need be specified in the
notice or wavier of notice of such meeting.
