ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION The aggregate purchase price of the 5,911,890 shares of Common Stock owned by the Purchasers is $202,759,529.36, including brokerage commissions. The shares of Common Stock owned by the Purchasers were acquired with working capital. ITEM 4. PURPOSE OF TRANSACTION The Reporting Persons purchased the shares of Common Stock based on the Reporting Persons' belief that the shares of Common Stock, when purchased, were undervalued and represented an attractive investment opportunity. Most importantly, based on work done on behalf of the Reporting Persons by Schlumberger Data & Consulting Services and others, the Reporting Persons believe that the shallow conventional oil and gas assets of the Issuer in the Appalachian basin have not been fully analyzed or developed and that such actions can be accomplished in a cost effective manner, which would generate value for the Issuer and its stockholders. The Reporting Persons have communicated a summary of their research findings to the Issuer's management. In addition, the Reporting Persons believe that the Issuer's Appalachian acreage may contain exploration and development opportunities in deeper formations and in the Devonian shale formation. The Reporting Persons intend to communicate with the Issuer's management, its stockholders and others regarding the Appalachian oil and gas assets and to recommend that the value of the assets be fully analyzed and reported to the Issuer's stockholders, and that these assets be more fully utilized by the Issuer in an expeditious manner. Except as set forth in this Statement, the Reporting Persons have no present plans or proposals that relate to or would result in any transaction, event or action described in paragraphs (a) through (j) of Item 4 of the form of Schedule 13D promulgated under the Act. In pursuing their investment businesses, the Reporting Persons analyze the operations, capital structure and markets of companies, including the Issuer, on a continuous basis through analysis of documentation and discussions with knowledgeable industry and market observers and with representatives of such companies. From time to time, one or more of the Reporting Persons may hold discussions with third parties, the management of such companies or the board of directors of such companies in which the Reporting Person may suggest or take a position with respect to potential changes in the operations, management or capital structure of such companies as a means of enhancing stockholder value. Each of the Reporting Persons reserves the right, in light of its continuing analysis and discussions as described above and its ongoing evaluation of the market price of the Common Stock, conditions in the securities markets generally, general economic and industry conditions, its business objectives and other relevant factors, to change its plans and intentions at any time, as it deems appropriate. In particular, and without limiting the generality of the foregoing, any one or more of the Reporting Persons (and their respective affiliates) may purchase additional shares of Common Stock or other securities of the Issuer or may sell or transfer shares of Common Stock or other securities of the Issuer in public or private transactions, may distribute Common Stock or other securities of the Issuer in-kind to their partners or member, as applicable, may seek board representation, may make proposals concerning changes to the operations, management or capital structure of the Issuer, may enter into privately negotiated derivative transactions with institutional counterparties to hedge the market risk of some or all of their positions in the Common Stock or other securities, and/or may take any other action that might result in any transaction, event or action described in paragraphs (a) through (j) of Item 4 of the form of Schedule 13D promulgated under the Act. Any such transactions may be effected at any time or from time to time, subject to any applicable limitations imposed on the transactions by the Securities Act or other applicable law.

CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER Other than as described herein, there are no contracts, arrangements, understandings or relationships among the Reporting Persons, or between the Reporting Persons and any other person, with respect to the securities of the Issuer. On October 18, 2006, NMVSH was formed as a Delaware limited liability company for the purpose of carrying out its investment strategy which is the achievement of capital appreciation by investing in the Issuer through open market purchases of Common Stock and related securities and working together with NMV for the purpose of demonstrating to the Issuer's management values that can be achieved for the Issuer and its shareholders by exploiting more fully the Issuer's existing assets or otherwise. Pursuant to the Limited Liability Company Agreement of NMVSH, dated as of October 19, 2006 (the "LLC Agreement"), a copy of which is attached hereto as Exhibit 99.2, Vantage GP is the Class A Member and Managing Member of NMVSH (the "Class A Member" or "Managing Member") and CalPERS is the Class B Member of NMVSH (the "Class B Member"). NMVSH has no other members. The LLC Agreement provides that the Managing Member, subject to the provisions of the LLC Agreement, will have the sole and exclusive right and authority to manage and control the business and affairs of NMVSH. Subject to limited exceptions, the Class B Member will make all determinations with respect to all acquisitions and dispositions of the Issuer's securities by NMVSH and exercise all shareholder rights, including voting rights, relating to such securities. The Class B Member is required to consult with the Class A Member prior to making any such acquisitions or dispositions and in the exercise of such rights and to make a good faith effort to coordinate any acquisitions, dispositions or exercise of rights with acquisitions and dispositions of securities of the Issuer and exercise of rights relating to such securities by affiliates of the Class A Member. The LLC Agreement also provides that the Managing Member will, after consultation with the Class B Member, cause NMVSH to prepare and make all regulatory filings and public statements concerning NMVSH's investment in Common Stock, and have such discussions and correspondence with the Issuer's management, board of directors and stockholders as the Managing Member will determine in furtherance of the investment strategy of NMVSH. The Class B Member has also agreed to certain restrictions on the acquisition of securities of the Issuer by the Class B Member and its affiliates other than NMVSH. In addition, the Class B Member may not take any action that would require a regulatory filing by NMVSH, except for the disposition of securities of the Issuer. The LLC Agreement further provides that the Class A Member is entitled to an annual incentive allocation of a portion of the appreciation in the value of the Common Stock held by NMVSH equal to 20% of the amount by which the value of such Common Stock exceeds a specified index. To the extent that performance of Common Stock held by NMVSH in any year does not generally exceed the specified index, the performance in a subsequent period must first exceed the amount of any underperformance before the Class A Member is entitled to an incentive allocation. The foregoing summary of the LLC Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the LLC Agreement attached as Exhibit 99.2 and incorporated herein by reference. New Mountain has entered into a consulting agreement with Mr. F. Fox Benton III (the "Consulting Agreement"), a copy of which is attached hereto as Exhibit 99.3, pursuant to which Mr. Benton will advise and assist the NMV Entities with respect to their investment strategy regarding the Issuer. The Consulting Agreement provides that, as part of the compensation for Mr. Fox's services, Mr. Fox will be paid a success fee based upon the performance of the NMV Entities' investment in shares of Common Stock. The foregoing summary of the Consulting Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Consulting Agreement attached as Exhibit 99.3 and incorporated herein by reference. From time to time, each of the NMV Entities may lend portfolio securities to brokers, banks or other financial institutions. These loans typically obligate the borrower to return the securities, or an equal amount of securities of the same class, to the lender on demand and typically the borrower is entitled to exercise voting rights and to retain dividends during the term of the loan.
