This filing reports all transactions related to the phantom stock units in the plan allocated to the individual from his point of entry into the plan through March 31, 2009. Each phantom stock unit is the economic equivalent of one share of common stock. Subject to the provisions of the plan, the phantom stock units become payable only in common stock upon the officer/director's termination of service." /s/ Edward A Guthrie 2009-04-16
