                          AGREEMENT AND PLAN OF MERGER

         This AGREEMENT AND PLAN OF MERGER (the "Agreement"), dated as of 
August __, 1997, is by and among Howell Corporation, a Delaware corporation 
("Howell"), Howell Acquisition Corp., a Texas corporation and wholly owned 
subsidiary of Howell ("Newco"), and Voyager Energy Corp., a Texas corporation 
("Voyager"). Newco and Voyager are sometimes collectively referred to herein 
as the "Constituent Corporations."

                                 R E C I T A L S

         WHEREAS, the respective Boards of Directors of Howell, Newco and 
Voyager have approved the Merger (as defined below) of Newco with and into 
Voyager upon the terms and subject to the conditions set forth herein and in 
accordance with the Texas Business Corporation Act (the "Act"); and

         WHEREAS, for federal income tax purposes, it is intended that the 
Merger will be a reorganization under Sections 368(a)(1)(A) and 368(a)(2)(E) 
of the Internal Revenue Code of 1986, as amended (the "Code"); and

         WHEREAS, for accounting purposes, it is intended that the Merger 
will be accounted for as a purchase;

         NOW, THEREFORE, in consideration of the premises and the 
representations, warranties, covenants, agreements and conditions specified 
in this Agreement, the parties hereto agree as follows:
                                       
                                   ARTICLE I

                     THE MERGER; THE SURVIVING CORPORATION

         1.1. THE MERGER. Subject to the terms and conditions of this 
Agreement, at the Effective Time (as defined in Section 1.5), Newco shall be 
merged with and into Voyager and the separate corporate existence of Newco 
shall thereupon cease (the "Merger"). 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. The Articles of Incorporation and the Bylaws of Voyager in 
effect at the Effective Time shall be the Articles of Incorporation and the 
Bylaws of the Surviving Corporation until duly amended in accordance with the 
terms thereof and the Act.

         1.3. 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. The Merger shall become effective at the time at which such Articles 
of Merger have been duly filed with the Secretary of State of the State of 
Texas, and such time is herein referred to as the "Effective Time."

         1.6. FURTHER ASSURANCES. If at any time after the Effective Time the 
Surviving Corporation shall consider or be advised that any further deeds, 
bills of sale, assignments, assurances or any other actions or things are 
necessary, desirable or proper to vest, perfect or confirm, of record or 
otherwise, in the Surviving Corporation its rights, title or interest in, to 
or under any of the rights, properties or assets of either of the Constituent 
Corporations acquired or to be acquired by the Surviving Corporation as a 
result of, or in connection with, the Merger or otherwise to carry out the 
purposes of this Agreement, the officers and directors of the Surviving 
Corporation shall be authorized to execute and deliver, in the name and on 
behalf of each of the Constituent Corporations or otherwise, all such deeds, 
bills of sale, assignments and assurances and to take and do, in the name and 
on behalf of each of the Constituent Corporations or otherwise, all such 
other actions and things as may be necessary, desirable or proper to vest, 
perfect or confirm any and all right, title and interest in, to and under 
such rights, properties or assets in the Surviving Corporation or otherwise 
to carry out the purposes of this Agreement.

                                   ARTICLE II

                     CONVERSION OR CANCELLATION OF SHARES

         2.1.     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.

laws of the State of Texas and is qualified to do business as a foreign 
corporation in each jurisdiction in which the properties owned, leased or

Disclosure Letter (as defined below) lists all jurisdictions in which Voyager 
is qualified to do business as a foreign corporation. Voyager has the

Section 3.1.

                  (b) AUTHORIZED CAPITAL. The authorized capital stock of 
Voyager consists of (i) 750,000 shares of Voyager Common Stock and (ii) 
250,000 shares of Voyager Preferred Stock. The outstanding capital stock of 
Voyager as of the date hereof consists of 96,719 issued and outstanding 
shares of Voyager Common Stock and 6,267 issued and outstanding shares of

agreements or

                                      -5-


commitments (whether contingent or not) of any character relating to unissued 
capital stock or other securities of Voyager obligating Voyager to issue any 
shares of or other equity interests in, or securities or rights convertible 
into or exchangeable for shares of or other equity interests in, Voyager. 
Except for this Agreement, there are no agreements or understandings with 
respect to the voting, sale, transfer or registration of any shares of 
capital stock of Voyager to which Voyager is a party or to which any holder 
of capital stock of Voyager is a party.

                  (c) CORPORATE AUTHORITY. Prior to the date of this 
Agreement, the board of directors and the shareholders of Voyager, pursuant 
to Articles 5.01 and 5.03 of the Act, approved this Agreement and the 
consummation of the transactions contemplated hereby. Voyager has the full 
power and authority to enter into this Agreement and to consummate the 
transactions contemplated hereby, including without limitation the Merger. 
The execution and delivery of this Agreement and the consummation of the 
transactions contemplated hereby, including without limitation the Merger, 
have been duly and validly authorized by all necessary corporate action on 
the part of Voyager. 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. The execution and delivery 
of this Agreement by Voyager does not, and the consummation by Voyager of the 
transactions contemplated hereby, including without limitation the Merger, 
will not, constitute or result in (i) a breach or violation of, or a default 
under, the Articles of Incorporation or Bylaws of Voyager, (ii) the 
triggering of any right of first refusal or similar rights under any 
shareholder or partnership agreement to which Voyager is a party, or (iii) a 
breach or violation of, a default under, the creation of a right to 
terminate, the acceleration of or the creation of a lien, pledge, security 
interest or other encumbrance on assets pursuant to (with or without the 
giving of notice or the lapse of time) any provision of any agreement, lease, 
contract, note, mortgage, indenture, arrangement or other obligation of 
Voyager, or any law, rule, ordinance or regulation or judgment, decree, 
order, award or governmental or non-governmental permit or license to which 
Voyager is subject.

                  (e) LICENSES; COMPLIANCE WITH LAWS. Voyager holds all 
permits, licenses, variances, exemptions, orders and approvals from 
governmental authorities (collectively, the "Licenses") which are necessary 
to conduct its businesses and operations in the manner heretofore conducted 
(the "Voyager Business"), except for failures to hold such Licenses or

                                      -6-


to comply with such laws, rules and regulations which, in the aggregate, 
would not have a Material Adverse Effect. 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. Voyager has made 
available to Howell true and complete copies of the unaudited financial 
statements and related notes for Voyager (the "Financial Statements") as of 
and for the years ended December 31, 1995 and December 31, 1996 and as of and 
for the five months ended May 31, 1997. 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. Except 
as set forth in the Disclosure Letter, since May 31, 1997, Voyager has not 
taken any action prohibited by Section 4.1(b) hereof or conducted its 
business other than in the ordinary and usual course.

                  (h) GOVERNMENTAL FILINGS AND CONSENTS. No notices, reports 
or other filings ("Governmental Filings") are required to be made by Voyager 
with, nor are any consents, registrations, approvals, permits or 
authorizations ("Governmental Consents") required to be obtained by Voyager 
from, any governmental or regulatory authorities of the United States, the 
several states or any foreign jurisdiction in connection with the execution 
and delivery of this Agreement by Voyager and the consummation of the 
transactions contemplated hereby, except for the filing and recordation of 
Articles of Merger in accordance with the Act.

                                      -7-


                  (i) LITIGATION. Except as set forth in the Disclosure 
Letter, there are no actions, suits, investigations or proceedings pending 
or, to the knowledge of Voyager or the Shareholders, threatened against 
Voyager.

                  (j) UNDISCLOSED LIABILITIES. Except as set forth in the 
Disclosure Letter or disclosed or specifically reserved against in the 
Financial Statements, Voyager has not incurred or otherwise become liable for 
any direct or indirect material liability, indebtedness, obligation, expense, 
claim, deficiency, guaranty or endorsement of or by any person 
("Liabilities") except for Liabilities arising in the ordinary course of 
business consistent with past practice or in connection with the transactions 
contemplated by this Agreement. 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.

                  (m) POWERS OF ATTORNEY AND CERTAIN AUTHORIZED PERSONS. No 
person holds a power of attorney from Voyager. No person other than the 
executive officers of Voyager is authorized to borrow money or incur or 
guarantee indebtedness on behalf of Voyager.

                  (n) PROPERTIES. Voyager has marketable title to the Oil and 
Gas Properties (as defined below) of Voyager, all of which Oil and Gas 
Properties are set forth in the Disclosure Letter, and owns, free and clear 
of all liens, claims and encumbrances, all of the other material assets 
reflected on the Financial Statements as being owned by Voyager and all such 
assets thereafter acquired by Voyager (except to the extent that such assets 
have thereafter been disposed of in the ordinary course of business 
consistent with past practice). As used herein, "Oil and Gas Properties" 
means all rights, titles, leasehold and other interests and estates in and to 
oil and gas leases, oil, gas and mineral leases, or other liquid or gaseous 
hydrocarbon leases, mineral fee interests, overriding royalty and royalty 
interests, net profit interests and production payment interests, including 
any reversionary or residual interests of whatever nature.

                  (o) PATENTS, COPYRIGHTS, SERVICE MARKS AND TRADEMARKS. 
Voyager is not the owner of any registered patent, copyright, trademark, 
servicemark, tradename or servicename. Voyager has full and sufficient rights 
to use and practice all technology, trade secrets, know-how and other 
proprietary information used or practiced in the operation of its businesses, 
free and clear of all liens, encumbrances, commitments, assignments, 
licenses, claims and rights of others. Voyager has not infringed and is not 
infringing on the right or interest of any other person or entity to or in 
any patent, copyright, trade or service mark or trade or service name. 
Voyager has no knowledge of any claim, whether actual or threatened, against 
Voyager for any such infringement.

                  (p) INSURANCE. All insurance coverage applicable to Voyager 
and the Voyager Business is in full force and effect, is valid, binding and 
enforceable in accordance with its terms against the respective insurers, 
insures Voyager in reasonably sufficient amounts against all risks usually 
insured against by persons operating similar businesses or properties in the 
localities where such businesses or properties are located and has been 
issued by insurers of recognized responsibility. To the knowledge of Voyager, 
there is no default under such coverage nor has there been any failure to 
give notice or present any claim under any such coverage in due and timely 
fashion. There are no outstanding past due unpaid premiums and no notice of 
cancellation or non-renewal of any such coverage has been received. Voyager 
does not know of the occurrence of any event which reasonably might form the 
basis of any claim against Voyager or its assets or properties or which might

                                      -9-


increase the insurance premiums payable for any such coverage, except for 
such claims and increases as would not in the aggregate have a Material 
Adverse Effect. There are no outstanding performance bonds covering Voyager 
or its operations which, individually or in the aggregate, are material to 
the Voyager Business.

                  (q) EMPLOYEES. Voyager has no employees.

                  (r) EMPLOYEE BENEFIT PLANS. There are no "employee benefit

Income Security Act of 1974, as amended ("ERISA"), and no other deferred 
compensation, stock purchase, stock option, stock incentive, other incentive, 
bonus, severance or fringe benefit plan, program, policy or arrangement, 
whether written or unwritten, formal or informal, that are maintained or 
contributed to by Voyager for the benefit of Voyager's employees. Voyager 
does not now, and has not at any time sponsored, maintained, adopted, 
contributed or been obligated to contribute to any employee pension benefit 
plans, pursuant to Section 3(2) of ERISA, for the benefit of Voyager's 
employees which are or ever were subject to the provisions of Title IV of 
ERISA. Voyager is not now, and has never been, a party to, or become subject 
to, any collective bargaining agreements with respect to Voyager's employees 
pursuant to which any of them has been, is or will become obligated to 
contribute to a "multi-employer plan" as that term is defined in Section 
4001(a)(3) of ERISA. Voyager is not now, and has never been, a part of either 
(A) a controlled group of corporations within the meaning of Section 414(b) 
of the Code, (B) a group of trades or businesses under common control within 
the meaning of Section 414(c) of the Code, or (C) an affiliated service group 
within the meaning of Section 414(m) of the Code, except as to which, in each 
case, Voyager has not incurred, and will not incur, any liability material to 
the financial condition, properties, businesses or results of operations of 
Voyager.

                  (s) TRANSACTIONS WITH AFFILIATES. No director or officer of 
Voyager or any member of the immediate family or any other of the affiliates 
of any of the foregoing owns or has an ownership interest in any corporation

with Voyager.

                  (t) ENVIRONMENTAL MATTERS. Except as set forth in the 
Disclosure Letter and except for matters which, individually or in the 
aggregate, could not reasonably be expected to have a Material Adverse 
Effect, (i) to the knowledge of Voyager, no Releases of Hazardous Materials

operated, or used (including third party sites at which disposals from the 
operations occurred) at any time by Voyager or its predecessors; (ii) since 
its formation there have not been any, and there are no pending or, to the

tanks, polychlorinated biphenyls, or asbestos-containing materials owned by 
Voyager, or located at any facility owned or operated by Voyager; (iv) to the

ownership, occupancy, use or transferability of any property owned, operated, 
or leased by Voyager; (v) Voyager has not disposed, treated, or arranged for

                           (i) Other than its 1996 federal income tax return and

         formally asserted or claimed, as to which the chief financial officer
         or the chief accounting officer or any other officer or employee of
