The Company and Sub are the only parties to the merger hereby contemplated and are sometimes referred to herein as the "Constituent Corporations," and the Company is sometimes referred to herein as the "Continuing Corporation." WITNESSETH: WHEREAS, the Company is an independent gas and oil producer engaged in the acquisition, exploitation, exploration, development and production of natural gas and oil primarily in West Virginia, Tennessee and Kentucky. WHEREAS, the respective Boards of Directors of the Constituent Corporations have approved this Agreement and deem it advisable and in the best interests of their respective corporations and stockholders that Sub merge with and into the Company on the terms and conditions herein set forth, whereby the Company will become a wholly-owned subsidiary of Buyer (the "Merger"). NOW, THEREFORE, for the purpose of consummating the above transaction and in consideration of the promises and mutual covenants herein contained, the parties hereby agree as follows: ARTICLE 1 DEFINITIONS As used in this Agreement, capitalized terms shall have the meanings specified in the text hereof or on Annex I hereto (which is incorporated herein by reference), which meanings shall be applicable to both the singular and plural forms of the terms defined. ARTICLE 2 THE MERGER 2.1 Effective Time of the Merger. Subject to the provisions of this Agreement, a Certificate of Merger (the "Certificate of Merger") in such form as required by the relevant provisions of the Delaware General Corporation Law (the "GCL") shall be duly prepared, executed and acknowledged by each of the Constituent Corporations and thereafter delivered to the Secretary of State of the State of Delaware for filing, as provided in the GCL, on the Closing Date. The Merger shall become effective upon the filing of the Certificate of Merger with the Secretary of State of the State of Delaware or at such time thereafter as is provided in the Certificate of Merger (the "Effective Time"). 2.2 Closing. The closing of the Merger (the "Closing") will take place at the offices of Kirkpatrick & Lockhart LLP, 1500 Oliver Building, Pittsburgh, Pennsylvania 15222-2312 at 10:00 a.m., prevailing time, on (i) the earlier of (A) October 15, 1997 and (B) the first Business Day after the last of the conditions set forth in Article 8 is fulfilled or waived, or (ii) on such other date as is specified by Buyer and the Company after all of the conditions to the Merger set forth in Article 8 have been satisfied or waived, subject to the rights of termination and abandonment hereinafter set forth (the "Closing Date"). 2.3 Effects of the Merger. (a) At the Effective Time (i) the separate existence of Sub shall cease and Sub shall be merged with and into the Company, (ii) the Certificate of Incorporation of the Company, as the Continuing Corporation, shall be amended to read in its entirety as set forth in Exhibit A, (iii) the Bylaws of Sub as in effect immediately prior to the Effective Time shall be the Bylaws of the Continuing Corporation, and (iv) the officers and A-1 6 directors of Sub at the Effective Time shall be the officers and directors of the Continuing Corporation and hold office as provided in the Bylaws of the Continuing Corporation. (b) At and after the Effective Time, the Continuing Corporation shall possess all the rights, privileges, powers and franchises of a public as well as of a private nature, and be subject to all the restrictions, disabilities and duties of each of the Constituent Corporations; and all and singular rights, privileges, powers and franchises of each of the Constituent Corporations, and all property, real, personal and mixed, and all debts due to either of the Constituent Corporations on whatever account, as well as for stock subscriptions and all other things in action or belonging to each of the Constituent Corporations, shall be vested in the Continuing Corporation, and all property, rights, privileges, powers and franchises, and all and every other interest shall be thereafter as effectually the property of the Continuing Corporation as they were of the Constituent Corporations, and the title to any real estate vested by deed or otherwise, in either of the Constituent Corporations, shall not revert or be in any way impaired; but all rights of creditors and all liens upon any property of either of the Constituent Corporations shall be preserved unimpaired, and all debts, liabilities and duties of the Constituent Corporations shall thereafter attach to the Continuing Corporation, and may be enforced against it to the same extent as if such debts and liabilities had been incurred by it. ARTICLE 3 CONVERSION OF SHARES; PAYMENT OF MERGER CONSIDERATION 3.1 Conversion of Shares. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of capital stock of Sub or the Company: (a) All issued and outstanding shares of Stock of the Company shall be canceled and extinguished and each share shall be converted into the right to receive $15.75 in cash (the "Merger Consideration"). Until surrendered, the certificates representing shares of the Company's Stock shall represent for all purposes only the right to receive the Merger Consideration. At and after the Effective Time, the holders of such certificates shall cease to have any rights as stockholders of the Company, except such rights, if any, as they may have pursuant to the GCL. (b) Each issued and outstanding share of the capital stock of Sub shall be converted into and become one validly issued, fully paid and non-assessable share of Common Stock, par value $.01 per share, of the Continuing Corporation. Until surrender, each certificate representing shares of Sub Common Stock shall, following the Merger, represent for all purposes a like number of shares of Common Stock of the Continuing Corporation as the number of shares of Common Stock of Sub formerly represented by such certificate. (c) The parties acknowledge that options to purchase shares of Stock (the "Options") shall not be converted into and become rights to purchase shares of Common Stock of the Continuing Corporation. Accordingly, the Company shall take all necessary action to provide that all options under the Benefit Plans listed on Schedule 4.16 shall become exercisable in full prior to the Effective Date of the Merger, in accordance with the terms of the relevant Benefit Plans. For purposes of this Agreement, all shares of Stock receivable upon exercise of the Options and the Warrant shall be deemed outstanding at the Effective Time of the Merger, to the extent the Options and the Warrant have not, in fact, been exercised, and holders of such Options and the Warrant shall be entitled to receive the Merger Consideration payable for the aggregate number of shares of Stock subject to such Options or the Warrant less the sum of (i) any applicable withholding and (ii) the aggregate amount of the exercise price for the aggregate number of shares of Stock subject to such Option or the Warrant. 3.2 Payment. (a) Simultaneously with the execution and delivery of this Agreement, $5,000,000 (the "Deposit Escrow") shall be delivered to Bank One, Texas, National Association to be held in escrow pursuant to the Escrow Agreement in the form of Exhibit B hereto (the "Escrow Agreement"). At the Closing, Buyer and the Company shall cause the Deposit Escrow to be released to the Disbursing Agent. A-2 7 (b) Five Business Days prior to the Effective Date, the Company shall designate a bank account to receive the Aggregate Merger Consideration. Sub shall, immediately prior and as a condition to the Merger, pay the Aggregate Merger Consideration less the amount of the Deposit Escrow by wire transfer to the account designated by the Company and such Aggregate Merger Consideration shall thereafter be disbursed to the stockholders of the Company by the Disbursing Agent. (c) As soon as practicable after the Effective Time, the Disbursing Agent shall mail or otherwise cause to be delivered to each record holder of certificates representing shares of the Company's Stock who has not already delivered a transmittal form and related stock certificates to the Disbursing Agent, a notice and transmittal form for use in effecting the surrender of such holder's stock certificates for payment therefor. Upon surrender to the Disbursing Agent of stock certificates together with such letter of transmittal duly executed, the holder of such certificate(s) shall be entitled to receive in exchange therefor cash in an amount equal to the product of the number of shares of Stock previously represented by such certificate and the Merger Consideration, and such certificate shall forthwith be canceled. Any cash deposited with the Disbursing Agent for payment to former stockholders of the Company pursuant to this Agreement which remains unclaimed after the expiration of six months after the Effective Date shall be delivered to the Continuing Corporation by the Disbursing Agent (together with any interest earned thereon) and thereafter the Disbursing Agent shall not be liable to any person claiming the same and former stockholders of the Company shall be entitled to look only to the Company (subject to abandoned property, escheat and other similar laws) for payment of the Merger Consideration upon due surrender of their stock certificates. (d) All payments made in respect of shares of Stock of the Company which are made in accordance with the terms of this Article shall be deemed to have been made in full satisfaction of all rights pertaining to such shares of Stock.
