Voyager shall be the surviving corporation of the Merger (sometimes hereinafter referred to as the "Surviving Corporation") and shall continue to be governed by the laws of the State of Texas, and the separate corporate existence of Voyager, with all the rights, privileges, powers and franchises of each of the Constituent Corporations, shall continue unaffected by the Merger. The Merger shall have the effects specified in the Act. 1.2. ARTICLES OF INCORPORATION AND BYLAWS OF THE SURVIVING CORPORATION.

DIRECTORS AND OFFICERS OF THE SURVIVING CORPORATION. The directors and officers of Voyager shall, from and after the Effective Time, be the directors and officers of the Surviving Corporation until their respective successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Surviving Corporation's Articles of Incorporation and Bylaws. 1.4. CLOSING. The Closing of the Merger (the "Closing") shall take place at such place and time as the parties hereto may agree, on the soonest practicable date following the fulfillment or, to the extent permissible, the waiver of all of the conditions to Closing set forth in Article V hereof. The "Closing Date" shall be the date on which the Closing occurs. 1.5. EFFECTIVE TIME. On the Closing Date, Newco and Voyager shall cause Articles of Merger effecting the Merger to be properly executed and filed with the Secretary of State of the State of Texas in accordance with the Act.

VOYAGER COMMON STOCK AND VOYAGER PREFERRED STOCK. (a) At the Effective Time, each share of common stock, no par value, of Voyager (the "Voyager Common Stock") and each share of preferred stock, no par value, of Voyager (the "Voyager Preferred Stock") issued and outstanding immediately prior to the Effective Time (except for shares of Voyager Common Stock and Voyager Preferred Stock then held in the treasury of Voyager, which shares shall be canceled and retired in accordance with Section 2.1(c)), shall by virtue of the Merger and without any action on the part of the holder thereof, be converted into the right to receive 3.424135319 shares (the "Share Fraction") of common stock, par value $1.00 per share, of Howell (the "Howell Common Stock"); provided that, in lieu of the issuance of any fractional share of Howell Common Stock, the number of shares of Howell Common Stock that each holder of shares of Voyager Common Stock or Voyager Preferred Stock will become entitled to receive pursuant to this Section 2.1(a) (after taking into account all shares of Voyager Common Stock and Voyager Preferred Stock held by such holder) shall be rounded to the nearest whole number of shares of Howell Common Stock. The consideration described above to be received by the holders of Voyager Common Stock and Voyager Preferred Stock pursuant to the Merger is hereinafter referred to collectively as the "Merger Consideration." At the Effective Time, all of the shares of Voyager Common Stock and Voyager Preferred Stock which, by virtue of the Merger and without any action on the part of the holders thereof, are converted into the right to receive the Merger Consideration shall cease to be outstanding, shall be canceled and retired and shall cease to exist, and each holder of a certificate formerly representing any such shares (a "Voyager Certificate") shall thereafter cease to have any rights with respect to such shares of Voyager Common Stock or Voyager Preferred Stock, except the right to receive the Merger Consideration for such shares of Voyager Common Stock or Voyager Preferred Stock upon the surrender of such Voyager Certificate in accordance with Section 2.3. (b) If after the date hereof and prior to the Effective Time Howell shall have declared a stock split (including a reverse split) of Howell Common Stock or a dividend payable in Howell Common Stock, or any other distribution of securities to holders of Howell Common Stock with respect to their Howell Common Stock, then the Share Fraction shall be proportionately adjusted to reflect such stock split, dividend or other distribution of securities. -3- (c) At the Effective Time, each share of Voyager Common Stock or Voyager Preferred Stock held in the treasury of Voyager shall, by virtue of the Merger and without any action on the part of Voyager, be canceled and retired and cease to exist without payment of any consideration therefor. 2.2. NEWCO COMMON STOCK. At the Effective Time, each share of common stock, par value $.01 per share, of Newco (the "Newco Common Stock") issued and outstanding immediately prior to the Effective Time shall be converted into one share of Voyager Common Stock. As soon as practicable after the Effective Time, the Surviving Corporation shall cause to be issued to Howell a certificate representing the shares of Voyager Common Stock into which the Newco Common Stock has been converted. 2.3. EXCHANGE OF VOYAGER COMMON STOCK AND VOYAGER PREFERRED STOCK FOR MERGER CONSIDERATION. (a) At the Closing or as soon as practicable thereafter, each holder of shares of Voyager Common Stock or Voyager Preferred Stock shall surrender to Howell for cancellation the Voyager Certificate(s) held by such holder, together with a duly executed Letter of Transmittal in the form of Exhibit 2.3(a) hereto. Upon surrender of such Voyager Certificate(s), such holder shall be entitled to receive in exchange therefor a certificate or certificates representing the number of shares of Howell Common Stock to which such holder shall have become entitled pursuant to the provisions of Section 2.1(a). Any holder of a Voyager Certificate(s) that has been lost or destroyed may nevertheless obtain the Merger Consideration into which the shares of Voyager Common Stock or Voyager Preferred Stock represented by such Voyager Certificate(s) have been converted pursuant to the provisions of Section 2.1, provided such holder delivers to Howell a statement certifying such loss or destruction and providing for indemnity reasonably satisfactory to Howell against any loss or expense it may incur as a result of such lost or destroyed Voyager Certificate(s) being thereafter surrendered to Howell. Until surrendered in accordance with the provisions of this Section 2.3(a), each Voyager Certificate shall represent, for all purposes, only the right to receive the Merger Consideration. (b) No dividends or distributions declared with a record date after the Effective Time with respect to Howell Common Stock shall be paid to persons entitled to receive Howell Common Stock in the Merger until such persons have surrendered their Voyager Certificates in accordance with Section 2.3(a). Promptly after such surrender, there shall be paid to the person in whose name Howell Common Stock shall be issued any dividends or distributions on such Howell Common Stock which shall have a record date after the Effective Time and prior to such surrender. If the payment date is after the date of such surrender, such payment shall be made on the payment date. -4- (c) In no event shall the persons entitled to receive dividends or distributions on shares of Howell Common Stock pursuant to Section 2.3(b) be entitled to receive interest on such dividends or distributions. All deliveries and payments in respect of shares of Voyager Common Stock and Voyager Preferred Stock which are made in accordance with the terms hereof shall be deemed to have been made in full satisfaction of all rights pertaining to such securities, except as may be otherwise required by law.

This Agreement has been duly and validly executed and delivered by Voyager and constitutes a legal, valid and binding agreement of Voyager enforceable against Voyager in accordance with its terms, except that (i) such enforcement may be subject to bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other similar laws now or hereafter in effect relating to creditors' rights and (ii) the remedy of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and to the discretion of the court before which any proceeding therefor may be brought. (d) NO CONFLICTS OR VIOLATIONS.

No event has occurred with respect to any of the Licenses which permits, or after notice or lapse of time or both would permit, revocation or termination thereof or would result in any impairment of the rights of the holder of any such License, except for revocations, terminations and impairments which, in the aggregate, would not have a Material Adverse Effect. Voyager is in compliance with all federal, state, local and foreign laws, ordinances, codes, regulations, orders, requirements, standards and procedures, which are applicable to the business of Voyager, except for failures so to comply which would not have a Material Adverse Effect. (f) FINANCIAL STATEMENTS; RESERVE REPORT.

The Financial Statements fairly present the financial position and results of operations of Voyager as of the dates and for the periods specified therein; provided, however, that Voyager maintained its books and records on the accrual basis of accounting, and, accordingly, although such financial statements were prepared on a best efforts basis and in good faith by Voyager, they include estimates and accrued items. Voyager has delivered to Howell a copy of its internally prepared reserve report (the "Reserve Report") dated as of June 1, 1997 relating to the oil and gas reserves attributable to Voyager's Oil and Gas Properties (as defined in Section 3.1(n)). The estimates of reserves in the Reserve Report were prepared in accordance with geological and engineering methods generally accepted in the oil and gas industry. (g) ABSENCE OF CERTAIN CHANGES. Except as set forth in the Disclosure Letter and except for declines in production of oil and gas, since May 31, 1997, Voyager has not undergone or suffered any change in its financial condition, properties, business or results of operations which has been, individually or in the aggregate, materially adverse to Voyager.

Voyager does not know of any basis for assertion against Voyager of any Liabilities not adequately reflected in the Financial Statements. (k) EMPLOYMENT AND NONCOMPETITION AGREEMENTS. Except for such as may be terminated without penalty within 30 days and except for Area of Mutual Interest Agreements relating to Voyager's Oil and Gas Properties (as defined in Section 3.1(n)), Voyager is not a party to any employment, consulting, noncompetition, nonsolicitation or other similar agreement. (l) MATERIAL CONTRACTS. All agreements, personal property and fixture leases, real property leases, contracts, notes, mortgages, indentures, arrangements or other obligations of Voyager that, in each case, are material (the "Material Contracts") are valid, binding and enforceable in accordance with their terms except to the extent limited by bankruptcy or other laws affecting creditors' rights generally. True, correct and complete copies of all Material Contracts have been made available to Howell, and all of the Material Contracts that relate to (i) indebtedness of Voyager, (ii) the payment or receipt of payment by Voyager of $50,000 or more in any twelve month period, or (iii) the delivery or performance or receipt by Voyager of goods or services with a value of $50,000 or more during any twelve month period are listed in the Disclosure Letter. Voyager has fulfilled, or will be able to fulfill when due, all of its obligations under the Material Contracts, except for failures to fulfill its obligations which, in the aggregate, would not have a Material Adverse Effect. No default by Voyager under any Material Contract has occurred and is continuing, except for any default which would not give another person the right, with or without giving of notice or lapse of time, or both, to terminate or materially modify the terms of such contract and except for terminations and modifications which would not have a Material Adverse Effect. Voyager has no knowledge of any material default or claimed, threatened or alleged material default by any other party under any term or provision of any Material Contract. There are no developments known to Voyager materially affecting any Material Contract that might prevent Voyager from realizing the benefits of any such Material Contract or that might prevent the Surviving Corporation from realizing such benefits after the completion of the Merger. Except as set forth in the Disclosure Letter, no -8- consents or approvals of any party to any Material Contract are required to be obtained by Voyager in connection with the execution and delivery of this Agreement by Voyager and the consummation of the transactions contemplated hereby.
