        is organized and existing under the laws of the State of Delaware,
        expressly assumes the due and punctual payment of, and all obligations

        direct or indirect debt obligations of any kind; provided, however, that
        the Corporation shall not issue, assume or guarantee any debt or other
        liability (regardless of unanimous board of directors approval) unless
        such debt or other liability will not result in the downgrade or
        withdrawal of the rating then assigned to any outstanding Securities
        then rated by any rating agency.

        (e) In approving any of the actions in clauses (3), (4) or (6) or clause

        any other entity, including any corporate parent or other affiliate of
        the Corporation, provided that such restriction shall not preclude the

        shareholder of the Corporation, so long as all such transactions are
        properly reflected on the books and records of the Corporation;

           (2) the Corporation shall pay from its own funds all obligations and

prior act of the directors which would have been valid if such bylaw had not
been adopted.

        EIGHTH: Personal Liability of Directors. A director of this Corporation
