     This corporation shall, to the fullest extent permitted by Delaware law in
effect from time to time, indemnify any person against all liability and expense

request of this corporation as a director, officer, partner or trustee of, or in
any similar managerial or fiduciary position of, or as an employee or agent of,
another corporation, partnership, joint venture, trust, association or other

application.

trust, association or other entity in which one or more of its directors or
officers are directors or officers, or have a financial interest,
notwithstanding such relationships and notwithstanding the fact that the
director or officer is present at or participates in the meeting of the board of
directors or committee thereof which authorizes the contract or transaction.

                                   ARTICLE XII

and its creditors or any class of them and/or between this corporation and its

any reorganization of this corporation as a consequence of such compromise or

binding on all the creditors or class of creditors, and/or on all the
