purpose(s) as the Board of Directors may from time to time determine.

               Shares of Preferred Stock may be issued from time to time in one

purposes as prescribed by applicable law, with each holder of record of shares
of Common Stock having voting power being entitled to one vote for each share of
Common Stock registered in his or its name on the books, registers and/or
accounts of the Company.

employee or agent of another corporation, partnership, joint venture, employee
benefit plan, trust or other enterprise, against expenses (including attorneys'
