Other material events

On November 1, 2006, Frontier Oil Corporation issued a press release announcing that the Los Angeles Superior Court hearing the Beverly Hills Lawsuits has entered an order granting summary judgment in favor of Frontier Oil Corporation (Frontier). As a result of this order, the plaintiffs in the Beverly Hills Lawsuits can no longer prosecute claims against Frontier, either for Frontier’s alleged direct liability or for any of the plaintiff’s claims against Wainoco Oil & Gas Company (WOGC), a subsidiary of Frontier. The Court’s order, which may be appealed by the plaintiffs, pertains only to the claims against Frontier and not its subsidiary, WOGC, which remains a defendant. The press release is filed as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.
