Exxon filed a Form 3 on December 11, 1998, expressly disclaiming beneficial ownership of the Option Shares prior to the occurrence of certain triggering events. The merger of Lion Acquisition Subsidiary Corporation, a wholly-owned subsidiary of Exxon, with and into Mobil was consummated and became effective on November 30, 1999. The Option granted by Mobil to Exxon terminated at the effective time of the merger, and therefore will not be triggered under any circumstances. **Intentional misstatements or omissions of facts constitute Federal Criminal Violations.
