Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	The shares of common stock listed in Table I were cancelled at the effective time of the merger (the "Effective Time") contemplated by the Agreement and Plan of Merger, dated December 12, 2005, to which the Issuer and ConocoPhillips are parties (the "Merger Agreement"), and, in consideration of such cancellation, the Reporting Person became entitled to receive, for each such share of Issuer common stock, 0.7214 shares of ConocoPhillips common stock and $46.50.
(2)	1 for 1. Pursuant to the Merger Agreement, at the Effective Time, these phantom stock units ceased to be measured by the value of Issuer common stock and were converted into 14,778 phantom stock units measured by the value of ConocoPhillips common stock. These phantom stock units were acquired under the Company's deferred compensation plan, are fully vested, and are to be settled in cash upon retirement or other termination of employment.
(3)	Pursuant to the Merger Agreement, at the Effective Time, this option, which provided for 100% vesting immediately at the date of grant (July 12, 2001), ceased to represent a right to acquire shares of common stock of the Issuer and thereafter constituted a fully vested option to purchase 14,425 shares of ConocoPhillips common stock with an exercise price of $13.2370 per share.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
