the business and affairs of the Company.

                    (ii) OPERATION OF COMMITTEES. A majority of all the members
of a committee shall constitute a quorum for the transaction of business, and

misconduct, bad faith or gross negligence of such Manager or Officer or (ii) for

solely as a result of the inapplicability, or deemed inapplicability of such
provision of the Act), become liable under a judgment, decree or order of a

Company, then the Company shall indemnify such Member or Officer and hold such

or Officer was obligated to take or effect under this Agreement.
