(the "Company") hereby amends and supplements its Solicitation/Recommendation Statement on Schedule 14D-9 originally filed with the Securities and Exchange Commission on January 8, 2001 (the "Schedule 14D-9"). The Schedule 14D-9 relates to an offer by Marathon Oil Acquisition 1, Ltd., a Delaware corporation (the "Purchaser"), which is a direct wholly owned subsidiary of Marathon Oil Company ("Marathon"), an Ohio corporation, which is a direct wholly owned subsidiary of USX Corporation, a Delaware corporation ("USX"), to purchase all of the outstanding shares of common stock, par value $.001 per share (the "Common Stock"), of the Company, together with the associated common share purchase rights issued pursuant to the Rights Agreement dated as of February 24, 1999, as amended as of December 22, 2000, between the Company and Computershare Investor Services, L.L.C., as rights agent (collectively with the Common Stock, the "Shares"), at $19.00 per Share, net to the seller in cash, without interest thereon, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated January 8, 2000 (the "Offer to Purchase"), and the related Letter of Transmittal (which, together with any amendments or supplements thereto, collectively constitute the "Offer"), copies of which were filed as Exhibits (a)(1) and (a)(2), respectively, to the Schedule 14D-9. Capitalized terms used and not defined herein shall have the meanings set forth in the Schedule 14D-9. ITEM 8. ADDITIONAL INFORMATION. Item 8 of the Schedule 14D-9 is hereby amended and supplemented by adding the following subsection to the end thereof: (f) Legal Proceedings. On January 5, 2001, following the joint press release by Marathon and the Company on December 22, 2000 announcing the Merger Agreement, two purported stockholder class action complaints were filed against the Company and its five directors in the District Court, City and County of Denver, Colorado, entitled Harry Levy v. Pennaco Energy, Inc., et al., Case Number 01-CV-0072, and Richard Stearns v. Pennaco Energy, Inc., et al., Case Number 01-CV-0073 (the "Colorado Complaints"). On January 9, 2001, the day after the Purchaser commenced the Offer, two similar purported stockholder class action lawsuits were filed against the Company, its five directors and the Purchaser in the Delaware Court of Chancery entitled John Grillo v. Pennaco Energy, Inc., et al., C.A. No. 18606 NC, and Thomas Turberg v. Pennaco Energy, Inc., et al., C.A. No. 18607 NC (the "Delaware Complaints"). The allegations in the Colorado Complaints are identical, the only difference being the purported class representative in each action. Both Colorado Complaints allege the same grounds for relief, namely that the defendants breached their fiduciary duties to the Company's stockholders or are participating in a scheme to deprive the Company's stockholders of the true value of their investments in the Company. They further allege that the merger consideration to be paid to the Company's stockholders is unconscionable, unfair and grossly inadequate. The allegations in the Delaware Complaints are identical, the only difference being the purported class representative in each action. Both Delaware Complaints also allege that the Company's directors have breached their fiduciary duties to the Company's stockholders. Specifically, the Delaware Complaints allege that the documents disseminated by the defendants in connection with the Offer contained material deficiencies in disclosure and that, by disseminating those materials, the defendants violated their fiduciary duties. They also allege that the Company's directors breached their fiduciary duty of care and good faith by failing to make efforts to inform themselves of the best value available for the Company, and that the Purchaser participated in the breaches of fiduciary duties by the Company's directors by pursuing the transaction in these circumstances. Each of these lawsuits includes a request for a declaration that the action is properly maintainable as a class action, and each seeks relief including awards of unspecified damages and fees of attorneys and 1 3 experts. Each lawsuit also seeks to enjoin the transactions contemplated by the Merger Agreement, or to rescind the transactions in the event they are consummated (or, in the case of the Delaware Complaints, to obtain rescissory damages), and to require the Company's directors to place the Company up for auction or otherwise employ a process to ensure that the highest possible price is obtained for the Company. The Delaware Complaints also seek an order compelling the defendants to supplement the documents relating to the Offer to include all material information not currently disclosed. The plaintiff in one of the Delaware lawsuits has filed a motion for preliminary injunction and a motion for expedited proceedings in the Delaware Court of Chancery. Each of the Company, its directors and the Purchaser believes these lawsuits and the claims made therein are without merit and intends to defend against these lawsuits vigorously. The Purchaser, Marathon and USX have filed copies of each of the Colorado Complaints, the Delaware Complaints and the motions in the Delaware lawsuit referred to above as exhibits to Amendment No. 1 to the Schedule TO, dated January 12, 2001, which are incorporated herein by reference.
