(1) This amended report is being filed to correct the number of shares of Chevron Corporation common stock received in exchange for 107,373 shares of Unocal Corporation common stock in connection with the merger of Unocal Corporation and a wholly-owned subsidiary of Chevron Corporation (the "Merger") pursuant to the Agreement and Plan of Merger dated as of April 4, 2005, as amended by Amendment No. 1 to the Agreement and Plan of Merger dated as of July 19, 2005 ("Merger Agreement"). The acquisition of 62,308 shares of Chevron Corporation common stock reported in the Form 4 filed on August 12, 2005 was based on both the merger consideration estimated to be paid and the preliminary results of the merger consideration elections (which were the only available information at the Form 4 filing deadline). Furthermore, the August 12, 2005 Form 4 did not reflect the withholding of 28,137 shares which were withheld for taxes and thus deemed to be disposed of, resulting in a net total of 34,764 shares of Chevron Corporation common stock received in the exchange.
(2) The price is based on the average of the high and low prices of Chevron Corporation common stock listed by the New York Stock Exchange on August 11, 2005.
(3) This amended report is being filed to correct the number of shares of Chevron Corporation common stock received in exchange for 26,373 shares of Unocal Corporation common stock pursuant to the Merger Agreement. The acquisition of 15,304 shares of Chevron Corporation common stock reported in the Form 4 filed on August 12, 2005 was based on both the merger consideration estimated to be paid and the preliminary results of the merger consideration elections (which were the only available information at the Form 4 filing deadline).
(4) This amended report is being filed to correct the number of shares of Chevron Corporation common stock received in exchange for 8,838 shares of Unocal Corporation common stock pursuant to the Merger Agreement. The acquisition of 5,128 shares of Chevron Corporation common stock reported in the Form 4 filed on August 12, 2005 was based on both the merger consideration estimated to be paid and the preliminary results of the merger consideration elections (which were the only available information at the Form 4 filing deadline).
