the holders of outstanding stock having not less than the minimum number of
votes that would be necessary to authorize or take such action at a meeting at
which all shares entitled to vote thereon were present and voted. Prompt notice

or any committee thereof may participate in a meeting of such board or committee
by means of conference telephone or similar communications equipment by means of
which all persons participating in the meeting can hear each other, and

in person at such meeting.

         Section 10. Action of Directors Without a Meeting. Any action required
or permitted to be taken at any meeting of the board of directors or of any
committee thereof may be taken without a meeting if all members of the board or
of such committee, as the case may be, consent


                                       7

thereto in writing and such written consent is filed with the minutes or
proceedings of the board or such committee.

stated salary for their services, but by resolution of the board of directors a
fixed sum and expenses of attendance, if any, may be allowed for attendance at
such regular and special meeting of the board or of any committee thereof.
Nothing herein contained shall be construed so as to preclude any director from

stockholders, subsidiaries or affiliated corporations in any capacity, and
receiving compensation therefor.

have and may exercise the powers of the board of directors in the management of
the business and affairs of the corporation, and may authorize the seal of the
corporation to be affixed to all papers which may require it; provided, however,
that in the absence or disqualification of any member of such committee or
committees, the member or members thereof present at any meeting and not
disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the board of directors to act at the
meeting in the place of any such absent or disqualified member. Such committee
or committees shall have such name or names as may be determined from time to
time by resolution adopted by the board of directors. Each committee shall keep
