an asserted conflict of interest.

such meeting and waiver of any and all objections to the place of the meeting,
the time of the meeting, or the manner in which it has been called or convened,
except when a Director states, at the beginning of the meeting, any objection to
the transaction of 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
waiver of notice of such meeting.

     A majority of the Directors present, whether or not a quorum exists, may
adjourn any meeting of the Board of Directors to another time and place. Notice

adjourned meeting are announced at the time of the adjournment, to the other
Directors.

Corporation or by any two Directors.

     Members of the Board of Directors may participate in a meeting of such
Board by means of a conference telephone or similar communications equipment by

at a meeting.

meeting of the Board of Directors, or any action which may be taken at a meeting
of the Board of Directors or a committee thereof, may be taken without a meeting
if a consent in writing, setting forth the action so to be taken, signed by all
the Directors, or all the members of the committee, as the case may be, is filed
in the minutes of the proceedings of the Board or of the committee. Such consent
shall have the same effect as a unanimous vote.
