Explanation of Responses:

1. 51,384 of 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. The remaining 8,500 of the shares of common stock listed in Table I were converted at the Effective Time into 12,261 shares of ConocoPhillips common stock.

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 172,092 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. 1 for 1. These units were granted under the Issuer's 2005 Performance Share Unit Plan. At the Effective Time, the Reporting Person became vested in, and entitled to a cash payment with respect to, 4,300 performance stock units in accordance with the provisions of the plan and the Merger Agreement, and the remaining unvested performance stock units were forfeited at that time.

4. Pursuant to the Merger Agreement, at the Effective Time, this option, which provided for 100 % vesting after one year following the date of grant (January 21, 2004), ceased to represent a right to acquire shares of common stock of the Issuer and thereafter constituted a fully vested option to purchase 57,702 shares of ConocoPhillips common stock with an exercise price of $20.3511 per share.

5. Pursuant to the Merger Agreement, at the Effective Time, this option, which provided for vesting in two equal annual installments following the date of grant (January 26, 2005), ceased to represent a right to acquire shares of common stock of the Issuer and thereafter constituted a fully vested option to purchase 50,489 shares of ConocoPhillips common stock with an exercise price of $30.6506 per share.

6. With the respect to 2,200 of the 35,000 shares underlying this option, the expiration date is January 25, 2015.

7. Pursuant to the Merger Agreement, at the Effective Time, this option, which provided for vesting in two equal annual installments following the date of grant (January 25, 2006), ceased to represent a right to acquire shares of common stock of the Issuer and thereafter constituted an option to purchase 43,276 shares of ConocoPhillips common stock with an exercise price of $62.9925 per share.

8. With the respect to 1,100 of the 30,000 shares underlying this option, the expiration date is January 24, 2016.
