                                     PART I

ITEM 1.  BUSINESS

A.   GENERAL

     Howell Corporation and its subsidiaries ("Company") are engaged in the 
exploration, production, acquisition and development of oil and gas 
properties. These operations are conducted in the United States. A 
description of the Company's principal business segment and the market in 
which it operates is summarized below. For information relating to industry 
segments, reference is made to "Management's Discussion and Analysis of 
Financial Condition and Results of Operations" and the Consolidated Financial 
Statements and Notes thereto.

     RECENT EVENTS

     On January 4, 1999, the Company sold its right to participate in the 
future earnings of Specified Fuels & Chemicals, Inc. ("SFC") for $2.0 
million. SFC acquired the Company's research and reference fuel business in 
July 1997.

     On January 29, 1999, the Company sold its interest in the LaBarge field 
for $15.8 million.

     On March 16, 1999, the Company received a refund of $5.7 million for 
Federal taxes paid in prior years.

     On March 19, 1999, the Company signed an agreement to sell its interest 
in the Pitchfork and Grass Creek Wyoming fields for $12.4 million.

     The cumulative proceeds from these events, totaling $35.9 million, have 
been or will be used to reduce bank debt. By utilizing this $35.9 million and 
part of the $5.9 million cash and cash equivalents available at December 31, 
1998, the Company will be able to pay off Tranche B and reduce Tranche A to 
approximately $84 million. See Item 2. "Properties" and see Note 6 of Notes 
to Consolidated Financial Statements.

     OIL AND GAS EXPLORATION AND PRODUCTION

        The Company's oil and gas exploration and production activities are 
conducted entirely within the United States by Howell Petroleum Corporation 
("HPC"), a wholly-owned subsidiary of the Company, and are concentrated in 
Wyoming and along the Gulf Coast, both onshore and offshore. At December 31, 
1998, the Company's estimated proved reserves were 29.9 million barrels of 
oil and plant liquids and 78.8 billion cubic feet ("BCF") of gas. The core 
area for the Company includes the Salt Creek, Elk Basin and Grass Creek 
fields discussed below. The Company's major producing properties include Salt 
Creek, Elk Basin, North Frisco City, Main Pass 64, Grass Creek and LaBarge 
fields. These six major fields represent 36.0 million barrels of oil 
equivalent ("MMBOE"), or 84% of the Company's total proved reserves. 
Substantially all of the Company's oil and natural gas production is sold on 
the spot market or pursuant to contracts priced according to the spot market. 
HPC has 108 employees.

          Effective May 22, 1998, HPC entered into a Settlement Agreement and 
Release with Amoco Production Company ("Amoco") and Snyder Oil Corporation 
("SOCO") whereby the parties agreed to settle the pending litigation between 
them styled: SNYDER OIL CORPORATION, PLAINTIFF V. AMOCO PRODUCTION COMPANY 
AND HOWELL PETROLEUM CORPORATION, DEFENDANTS in the District Court, Ninth 
Judicial District, Civil Action No. 29861, Fremont County, Wyoming. Under the 
terms of the settlement, HPC agreed to relinquish its contractual rights to 
purchase that portion of the Amoco Wyoming package (the "Package") relating 
to the Beaver Creek Unit and the associated facilities. In addition, Amoco 
agreed to sell the Company an approximate 31% working interest in the Higgins 
Unit located in Sweetwater County, Wyoming, and a 1.95% overriding royalty 
interest covering over 78,000 acres in the Natural Buttes Field located in 
Uintah County, Utah. The purchase price for these predominately gas 
properties was $11 million. HPC's in-house petroleum engineers estimate total 
proved reserves attributable to these properties are 8.1 BCFE. Net daily 
production from the properties was approximately 1.8 million cubic feet 
("MMCF") of natural gas with a projected reserve-to-production index of 12 
years. This settlement completed the Company's acquisition of properties from 
Amoco ("the Acquisition"). The Company purchased proved reserves of 39.1 
MMBOE for $126.4 million which is an acquisition cost of $3.23 per barrel of 
oil equivalent. At year-end 1997, HPC had previously announced the closing on 
$115.4 million of this acquisition.

                                       1

<PAGE>

        The oil and gas industry is highly competitive. Major oil and gas 
companies, independent operators, drilling and production purchase programs, 
and individual producers and operators are active bidders for desirable oil 
and gas properties, as well as the equipment and labor required to operate 
those properties. Many competitors have financial resources substantially 
greater, and staffs and facilities substantially larger, than those of the 
Company.

        The Company's financial condition, profitability, future rate of 
growth and ability to borrow funds or obtain additional capital, as well as 
the carrying value of its oil and natural gas properties, are substantially 
dependent upon prevailing prices of, and demand for, oil and natural gas. The 
energy markets have historically been, and are likely to continue to be 
volatile, and prices for oil and natural gas are subject to large 
fluctuations in response to relatively minor changes in the supply and demand 
for oil and natural gas, market uncertainty and a variety of additional 
factors beyond the control of the Company. These factors include the level of 
consumer product demand, weather conditions, the actions of the Organization 
of Petroleum Exporting Countries, domestic and foreign governmental 
regulations, political stability in the Middle East and other petroleum 
producing areas, the foreign and domestic supply of oil and natural gas, the 
price of foreign imports, the price and availability of alternative fuels and 
overall economic conditions. A substantial or extended decline in oil and 
natural gas prices could have a material adverse effect on the Company's 
financial position, results of operations, quantities of oil and natural gas 
reserves that may be economically produced, carrying value of its proved 
reserves, borrowing capacity and access to capital.

     TECHNICAL FUELS AND CHEMICAL PROCESSING

        On July 31, 1997, Howell Hydrocarbons & Chemicals, Inc. ("Seller"), a 
wholly-owned subsidiary of the Company, sold substantially all of the assets 
of its research and reference fuels and custom chemical manufacturing 
business to SFC.

        The assets purchased by SFC included the fee property in Channelview, 
Texas, on which Seller's refinery was located, all refining facilities 
located on the fee property and all related personal property, all 
inventories of finished products, work in process, raw materials and supplies 
related to the business, substantially all of the accounts receivable on the 
closing date, all transferable intellectual property used primarily in the 
business and all of Seller's rights under various contracts and leases 
related to the business. In connection with the transaction, (a) SFC received 
a license to use the name "Howell Hydrocarbons & Chemicals" for a five-year 
period after closing and assumed certain obligations of Seller and the 
Company, and (b) the Company agreed not to engage (directly or through 
affiliates) in any competing business for a five-year period after the 
closing.

        The sale resulted in a pre-tax gain of $0.4 million and the proceeds 
of the sale were used by the Company to reduce its outstanding indebtedness. 
The sale completes the divestiture by the Company of all of its 
non-exploration and production businesses. In connection with the sale, the 
Company has given and received environmental and other indemnities. Should 
claims be made against the Company based on these indemnities, the company 
could be required to perform its obligations thereunder.

          In consideration for the assets sold to SFC, Seller and the Company 
received a payment of $19.8 million in cash, which included $14.8 million for 
the property, plant, equipment and related items, and $5.0 million in payment 
of working capital items. Seller was entitled to receive an additional 
payment equal to 55% of the amount by which SFC's "EBITDA" for each 
twelve-month period ending June 30, 1998, 1999, 2000, 2001 and 2002 exceeds 
the "Minimum EBITDA" (as defined in the Agreement). The Minimum EBITDA 
amounts for those years were $5.0 million, $5.175 million, $5.35 million, 
$5.525 million and $5.7 million, respectively. During August 1998, the 
Company received the first excess EBITDA payment of $0.7 million. SFC was 
entitled to repurchase Seller's rights to these additional payments at any 
time after June 30, 1998; generally by paying to Seller an amount equal to 
the greater of (a) the product obtained by multiplying the EBITDA payment 
amount for the immediately preceding twelve-month period by the number of 
twelve-month periods remaining, or (b) an amount fixed by the agreement, 
which was initially set at $5.7 million if the repurchase occurred during the 
twelve-month period ending on June 30, 1999, and which declines for each 
twelve-month period thereafter to $1.2 million if the repurchase occurred 
during the twelve-month period ending June 30, 2002. On January 4, 1999, SFC 
and Seller agreed that the amount fixed by the Agreement was not reasonable 
in light of current performance; therefore, Seller agreed to reduce the 
excess EBITDA payment to $2.0 million which SFC agreed to purchase.

     INVESTMENT IN GENESIS

        On December 1, 1996, Genesis Crude Oil, L.P., a Delaware limited 
partnership ("Buyer"), Genesis Energy, L.P., a Delaware limited partnership 
("MLP") and Genesis Energy, L.L.C., a Delaware limited liability company 
("LLC"), (collectively referred to hereinafter as "Genesis"), entered into a 
Purchase & Sale and Contribution & Conveyance Agreement ("Agreement") with 
Howell Corporation and certain of its subsidiaries ("Howell") and Basis 
Petroleum, Inc. ("Basis"), a subsidiary of Salomon Inc. ("Salomon"). Pursuant 
to the Agreement, Howell agreed to sell and convey certain of its assets to 
Buyer. These assets consisted of the crude oil gathering and marketing 
operations and pipeline operations of Howell ("Business").

        Buyer was formed by MLP and LLC to acquire the Business from Howell 
and similar assets from Basis. MLP is owned 98% by limited partners and 2% by 
LLC, which is the general partner. LLC is owned 46% by Howell and 54% by 
Basis. As a result of this transaction, Howell owns a subordinated limited 
partner interest in Buyer of 9.01%, a direct general partner interest in 
Buyer of 0.18% and a general partner interest through MLP of 0.74% of Buyer.

B.   GOVERNMENTAL AND ENVIRONMENTAL REGULATIONS

     GOVERNMENTAL REGULATIONS

        Domestic development, production and sale of oil and gas are 
extensively regulated at both the federal and state levels. Legislation 
affecting the oil and gas industry is under constant review for amendment or 
expansion, frequently increasing the regulatory burden. Also, numerous 
departments and agencies, both federal and state, have issued rules and 
regulations binding on the oil and gas industry and its individual members, 
compliance with which is often difficult and costly and some of which carry 
substantial penalties for failure to comply. State statutes and regulations 
require permits for drilling operations, drilling bonds and reports 
concerning wells. Texas and other states in which the Company conducts 
operations also have statutes and regulations governing conservation matters, 
including the unitization or pooling of oil and gas properties and 
establishment of maximum rates of production from oil and gas wells. The 
existing statutes or regulations currently limit the rate at which oil and 
gas is produced from wells in which the Company owns an interest. The 
Company's other business segments also operate under strict governmental 
regulations.

     ENVIRONMENTAL REGULATIONS

        The Company's operations are subject to extensive and developing 
federal, state and local laws and regulations relating to environmental, 
health and safety matters; petroleum; chemical products and materials; and 
waste management. Permits, registrations or other authorizations are required 
for the operation of certain of the Company's facilities and for its oil and 
gas exploration and production activities. These permits, registrations or 
authorizations are subject to revocation, modification and renewal. 
Governmental authorities have the power to enforce compliance with these 
regulatory requirements, the provisions of required permits, registrations or 
other authorizations, and lease conditions, and violators are subject to 
civil and criminal penalties, including fines, injunctions or both. Failure 
to obtain or maintain a required permit may also result in the imposition of 
civil and criminal penalties. Third parties may have the right to sue to 
enforce compliance. The cost of environmental compliance has not had a 
materially adverse effect on the Company's operations or financial condition 
in the past. However, violations of applicable regulatory requirements, 
environment-related lease conditions, or required environmental permits, 
registrations or other authorizations can result in substantial civil and 
criminal penalties as well as potential court injunctions curtailing 
operations.

        Some risk of costs and liabilities related to environmental, health 
and safety matters is inherent in the Company's operations, as it is with 
other companies engaged in similar businesses, and there can be no assurance 
that material costs or liabilities will not be incurred. In addition, it is 
possible that future developments, such as stricter requirements of 
environmental or health and safety laws and regulations affecting the 
Company's business or more stringent interpretations of, or enforcement 
policies with respect to, such laws and regulations, could adversely affect 
the Company. To meet changing permitting and operational standards, the 
Company may be required, over time, to make site or operational modifications 
at the Company's facilities, some of which might be significant and could 
involve substantial expenditures. In particular, federal regulatory programs 
focusing on the increased regulation of storm water runoff, oil spill 
prevention and response and air emissions (especially those that may be 
considered toxic) are currently being implemented. There can be no assurance 
that material costs or 

                                       3

<PAGE>

liabilities will not arise from these or additional environmental matters 
that may be discovered or otherwise may arise from future requirements of law.

        The Company has made a commitment to comply with environmental 
regulations. Personnel with training and experience in safety, health and 
environmental matters are responsible for compliance activities. Senior 
management personnel are involved in the planning and review of environmental 
matters.

C.   EMPLOYMENT RELATIONS

     On December 31, 1998, the Company had 126 employees. The Company's 
employees are not represented by a union for collective bargaining purposes. 
The Company has experienced no work stoppages or strikes as a result of labor 
disputes and considers relations with its employees to be good. The Company 
maintains group life, medical, dental, long-term disability, 401(K) Plan and 
accidental death and dismemberment insurance plans for its employees. 
Historically, the Company provided its employees with a Company stock 
purchase plan, a thrift plan and a Simplified Employee Pension Plan. During 
1998, the Company replaced these plans with a 401(K) plan with profit 
sharing. The company contributed $135,721 in employee matching funds during 
1998.

ITEM 2.  PROPERTIES

A.   SUPPLEMENTARY OIL AND GAS PRODUCING INFORMATION

     RECENT EVENTS

     The proposed sale of the Pitchfork and Grass Creek, Wyoming fields and 
the completed sale of LaBarge, Wyoming fields for a total of $28.2 million 
represent 7.0 million barrels of oil equivalent ("MMBOE") out of the 43.1 
MMBOE of the Company's proved oil and gas reserves at December 31, 1998 and 
approximately 2.2 MBOE per day of the Company's 11.9 MBOE 1998 daily 
production. These transactions also represent 460 gross and 135 net oil wells,
21 gross and 9 net gas wells, 10,409 gross and 2,508 net developed acres, and 
320 gross and 320 net undeveloped acres.

     RESERVES

     The Company's net proved reserves of crude oil, condensate and natural 
gas liquids (referred to herein collectively as "oil") and its net proved 
reserves of gas have been estimated by the Company's engineers in accordance 
with guidelines established by the Securities and Exchange Commission. The 
reserve estimates, except for the reserves purchased from Amoco, at December 
31, 1998, 1997, and 1996, were reviewed by independent petroleum consultants,
H. J. Gruy and Associates, Inc. The December 31, 1998 and 1997 reserves, 
associated with the properties acquired from Amoco, were reviewed by 
independent petroleum consultants, Ryder Scott & Associates. The estimates 
for 1995 were reviewed by L. A. Martin & Associates, Inc. These estimates 
were used in the computation of depreciation, depletion and amortization 
included in the Company's consolidated financial statements and for other 
reporting purposes.

</TABLE>
        Total proved reserves at year-end 1998 were 43,072 MBOE compared to 
56,109 MBOE at year-end 1997. The change was related almost entirely to 
downward revisions associated with lower oil and gas prices. The price 
sensitivity of the Company's reserve base is illustrated by the fact that if 
year-end 1998 reserves were calculated using year-end 1997 pricing, total 
proved reserves would have remained basically unchanged at 1997 reserve levels.

        Proved oil reserves at December 31, 1998, include 1.4 million 
barrels of natural gas liquids ("NGL").

        In addition to the oil and gas reserves shown above, the Company, 
through its participation in the LaBarge Project in southwestern Wyoming, had 
proved carbon dioxide reserves of 57,140 MMCF and proved helium reserves of 
2,570 MMCF at December 31, 1998. The LaBarge Project was sold in January 1999.

        OIL AND GAS LEASEHOLDS

        The following table sets forth the Company's ownership interest in 
leaseholds as of December 31, 1998. The oil and gas leases in which the 
Company has an interest are for varying primary terms, and many require the 
payment of delay rentals to continue the primary term. The leases may be 
surrendered by the Company at any time by notice to the lessors, by the 
cessation of production or by failure to make timely payment of delay rentals.

        STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO 
PROVED OIL AND GAS RESERVES. The accompanying table presents a standardized 
measure of discounted future net cash flows relating to the production of the 
Company's estimated proved oil and gas reserves at the end of 1998 and 1997. 
The method of calculating the standardized measure of discounted future net 
cash flows is as follows:

        (1) Future cash inflows are computed by applying year-end prices of oil
        and gas to the Company's year-end quantities of proved oil and gas
        reserves. Future price changes are considered only to the extent
        provided by contractual arrangements in existence at year-end.

        (2) Future development and production costs are estimates of
        expenditures to be incurred in developing and producing the proved oil
        and gas reserves at year-end, based on year-end costs and assuming
        continuation of existing economic conditions.

        (3) Future income tax expenses are calculated by applying the applicable
        statutory federal income tax rate to future pretax net cash flows.
        Future income tax expenses reflect the permanent differences, tax
        credits and allowances related to the Company's oil and gas producing
        activities included in the Company's consolidated income tax expense.

        (4) The discount, calculated at ten percent per year, reflects an
        estimate of the timing of future net cash flows to give effect to the
        time value of money.

by recent declines in both natural gas and crude oil prices, the reserves may 
be subject to material future revisions.

</TABLE>
        The Company's oil and gas exploration and production activities are 
conducted entirely within the United States by HPC and are concentrated in 
Wyoming and along the Gulf Coast, both onshore and offshore. At December 31, 
1998, the Company's estimated proved reserves were 29.9 MMBO and plant 
liquids and 78.8 BCF of gas. The Company's major producing properties include 
Salt Creek, Elk Basin, North Frisco City, Main Pass 64, Grass Creek and 
LaBarge fields. These six major fields represent 36.0 MMBOE, or 84% of the 
Company's total proved reserves. Substantially all of the Company's oil and 
natural gas production is sold on the spot market or pursuant to contracts 
priced according to the spot market.

     DESCRIPTION OF SIGNIFICANT PROPERTIES

     SALT CREEK. The Company owns and operates the Salt Creek Field in the 
Powder River Basin in Natrona County, Wyoming. The Company's working interest 
varies from 65% to 100% in this multi-pay field. The field underwent primary 
development beginning in 1908. In the 1960's a waterflood was installed in 
the "Light Oil Unit" ("LOU") which is unitized from the surface to the base 
of the Sundance 3 formation. There are currently 655 producing wells and 588 
injection wells located in the LOU on a flood pattern of approximately five 
acre well spacing. As of December 31, 1998, the field was producing a net of 
approximately 3,050 barrels per day of sweet crude oil, 275 barrels per day 
of sour crude and 50 barrels per day of NGLs.

          The most prolific producing formation in the LOU is the Wall Creek 
2 at a depth of 1,500 feet. It has produced approximately 386 MMBO from an 
original estimated 950 MMBO in place. In addition, the field has produced 
another 269 MMBO from multiple horizons varying in depth down to 4,000 feet. 
The Company believes that the application of horizontal drilling to target 
unswept intervals within several of the reservoirs may have positive 
production and reserve potential and plans to implement a pilot program in 
the future to test the application. In addition, the potential for enhanced 
oil recovery through CO2 flooding is under consideration for the Wall Creek 1 
and Wall Creek 2 formations. Another opportunity exists in the shallow shale 
formations that exist above the Wall Creek 1. The shale was developed in the 
1920s and produced over 2 MMBO in the LOU. The Company believes the oil 
resided in the extensive vertical fractures and fault systems prevalent in 
the shale and the reserves were not completely depleted in all areas of the 
field. The Company is investigating the application of horizontal drilling to 
connect these fracture systems and faults to a producing wellbore.

        ELK BASIN. The Company owns and operates the Elk Basin field, located 
in the Bighorn Basin in Park County, Wyoming and Carbon County, Montana. The 
productive horizons range in depth from 1,700 feet to 6,000 feet, with the 
majority of the production coming from the Embar-Tensleep and the Madison 
formations. As of December 31, 1998, the field was producing a net of 1,532 
barrels per day of oil and 226 barrels per day of NGLs from 215 producing 
wells.

                                       9

<PAGE>

        The Embar-Tensleep reservoir was an inert gas injection pressure 
maintenance project until injection into the gas cap was discontinued in the 
1970's. The company successfully re-established the inert gas injection to 
increase reservoir pressure in 1998, which is anticipated to have a positive 
impact on future production rates. In addition, the Company plans to 
supplement this gas cap injection with horizontal and vertical producing 
wells located in the oil rim on the edge of the structure, which could 
improve the sweep efficiency and ultimate recovery. The shallow Frontier 
formation, at a depth of 1,700 feet, holds a significant number of potential 
low cost drilling opportunities to extend the production in this field 
down-structure to the lowest known oil-water contact. Since 1986, 32 Frontier 
wells have been successfully drilled or recompleted within the Frontier Unit. 
These wells cost approximately $75,000 each, typically produce at rates of 30 
barrels per day of oil and have cumulative recoveries up to 60 thousand 
barrels each. The Company has identified numerous potential drilling 
locations within the unit and outside the unit on Company leasehold. The 
prolific Madison carbonate, at a depth of 5,000', has the potential for 
horizontal drilling due to its heterogeneous nature. In addition, this 
waterflooded reservoir has the potential to downspace the 72 producers from 
the current 40 acres per well to 20 acres per well based on the successful 
infill drilling program over the last 10 years.

        MAIN PASS BLOCK 64. Main Pass is located in federal waters offshore 
Louisiana about 70 miles southeast of New Orleans. The Company, as operator, 
discovered oil and gas upon drilling a test well in 1982. In 1989, the 
Company unitized portions of Main Pass blocks 64 and 65, covering the main 
pay sand (the "7,300' Sand Unit") and implemented a waterflood project to 
repressure the 7,300' Sand Unit. Through exploitation, additional 
acquisitions and field unitization, the Company currently has a working 
interest which averages approximately 80% in 24 gross wells, including 5 
injection wells. Gross cumulative production from the 7,300' Sand Unit over 
almost 17 years has totaled 11.3 MMBO and 26.6 BCF of natural gas. As of 
December 31, 1998, daily net production was approximately 706 barrels of oil. 
In 1998, after an internal comprehensive reservoir study indicated that the 
waterflood pushed the oil column into the original gas cap, the Company 
successfully completed a sidetrack operation to confirm and exploit these 
previously unrecoverable attic oil reserves. As a result of the drilling 
activity, the Company added net reserves of 1.8 MMBOE and has identified an 
additional 7 recompletions in the 7,300' Sand Unit.

        NORTH FRISCO CITY. The North Frisco City field, located in Monroe 
County, Alabama, was discovered in March 1991. Production is predominantly 
from the Frisco City sand member of the Haynesville formation at a depth of 
about 12,000 feet. Based on seismic data, ten successful development wells 
were completed from 1992 though 1994. In 1994, the field was unitized. The 
Company currently has a 24.1% working interest in nine gross producing wells 
in the unit. As of December 31, 1998, daily net production from this field 
was 690 barrels of oil, 173 barrels of natural gas liquids and 765 thousand 
cubic feet of natural gas. The Company also owns a royalty interest in this 
field.

        GRASS CREEK. The Grass Creek Unit, located in the Bighorn Basin in 
Hot Springs County, Wyoming, is operated by Marathon Oil Company. Oil was 
discovered in the Frontier formation in 1914. The Company's working interest 
within the Grass Creek field differs by horizon, varying from 13% in the 
Curtis to 37.65% in the Darwin. The company owns a 31% working interest in 
the primary horizons, the Phosphoria and Tensleep, which are mature 
waterfloods. Current net production is approximately 965 barrels of oil per 
day. In February 1996, a 3-D seismic survey was acquired over the field. 
Based upon that data, the Company has identified numerous potential drilling 
opportunities. In 1998, the operator successfully completed three deepenings 
and one drill well in the Phosphoria-Tensleep, confirming these 
opportunities. Grass Creek field is also a candidate for enhanced oil 
recovery using CO2. On March 19, 1999, the Company entered into an agreement 
to sell its interest in Grass Creek and other properties for $12.4 million.

        LABARGE PROJECT. The LaBarge Project, operated by Exxon Company USA, 
is located in southwestern Wyoming. The Company owns a 4.8% working interest 
in the Fogarty Creek Unit. The Company has an interest in 12 gross wells 
producing from depths between 14,500 feet to 17,000 feet in the Fogarty Creek 
Unit. The Company has significant production and reserves of carbon dioxide 
and helium and small amounts of production and reserves of sulfur from its 
interest in the LaBarge Project, which are not included in its production and 
proved reserves of oil and natural gas discussed elsewhere in Item 2. The 
following table presents information on the Company's net production of 
natural gas, carbon dioxide and helium attributable to the Company's interest 
in the LaBarge Project. The natural gas data from the LaBarge Project is also 
included in the other tables set forth elsewhere in Item 2. On January 29, 
1999, the Company sold all of its right, title, and interest in and to the 
LaBarge Project for $15.75 million.

     Due to the current market conditions, the Company's Board of Directors 
will evaluate on a quarterly basis whether or not to pay either common or 
preferred dividends. No assurance can be given, however, as to the timing and 
amount of any future dividends which necessarily will depend on the earnings 
and financial needs of the Company, legal restraints, and other 
considerations that the Company's Board of Directors deems relevant. The 
ability of the Company to pay dividends on its common stock is currently 
subject to certain restrictions contained in its bank loan agreement. See 
Item 7, "Management's Discussion and Analysis of Financial Condition - 
Liquidity and Capital Resources."

     In addition, the Company has 690,000 shares of convertible preferred 
stock outstanding. These shares were issued in April 1993. The $3.50 
convertible preferred stock is traded on the National Association of 
Securities Dealers, Inc. Automated Quotation System ("NASDAQ") under the 
symbol HWLLP. See Note 7 of Notes to Consolidated Financial Statements.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
RESULTS OF OPERATIONS

     The following is a discussion of the Company's financial condition, 
results of operations, capital resources and liquidity. This discussion and 
analysis should be read in conjunction with the Consolidated Financial 
Statements of the Company and the notes thereto.

     RESULTS OF CONTINUING OPERATIONS

     The Company's only principal business segment is oil and gas production. 
Crude oil marketing and transportation was also a principal segment until its 
sale on December 3, 1996. Results of continuing operations by segment for the

each segment's revenues does not reflect the elimination of intercompany 
revenues. See Notes 3 and 8 of Notes to Consolidated Financial Statements.

</TABLE>
     REVENUES

     During 1998 revenues for the oil and gas segment increased 48% when 
compared to the year ended 1997 due to the Amoco property Acquisition, 
partially offset by a 35% decrease in average oil prices and a 20% decrease 
in average natural gas prices. The increase in revenues were partially offset 
by the Company's continued reduction of its gas marketing activities.

     Revenues for 1997 increased primarily due to an increase in the natural 
gas price of 13% to $2.33 per thousand cubic feet. Minerals leasing activity 
steadily increased over the last three years. These revenue increases were 
partially offset by a decrease in gas marketing revenue due to reduced activity.

        Revenues from the sales of the La Barge other products are 
attributable to sales of carbon dioxide, helium and sulfur. Increased 
production levels of helium and carbon dioxide in 1997 relative to 1996 were 
partially offset by reduced product sales prices. Sulfur revenues were 
insignificant.

        OPERATING PROFIT

     Operating profits for the oil and gas segment decreased $98.9 million 
primarily due to pre-tax non-cash impairments of $102.2 million. On an 
after-tax basis, the impairments amounted to $67.4 million or a loss of 
$12.32 per common share. Excluding the impairments, the segment's operating 
profits increased 39% when compared to the year ended 1997. The Acquisition 
also resulted in increased lease operating expense and production and 
severance tax expense of $13.3 million and $2.8 million, respectively. A 
reduction of workover expense of $1.1 million helped to offset these 
increased costs. The Company's general and administrative expenses decreased 
$1.6 million due to increased administrative credits on some of the 
properties acquired in late 1997. Also offsetting these costs was a decrease 
in depreciation, depletion and amortization, excluding the impairments, per 
equivalent barrel of production from $5.18 in 1997 to $2.68 in 1998 due to 
the Acquisition.

     In 1997, the operating profit of this segment decreased $0.3 million 
when compared to 1996. The decrease was primarily due to increased workover 
expenses and LaBarge expenses. Workover costs increased from $1.1 million in 
1996 to $1.6 million in 1997 primarily due to platform refurbishment on Main 
Pass 64.

     Howell's average realized oil price, including hedging, for 1998 was 
$11.37 per barrel. The crude oil price decline that began in the latter part 
of the fourth quarter 1997 continued into early 1999.

        Lower oil and gas prices may continue for the near term. During such 
period, the Company's cash flow and funds available for reinvestment are 
reduced. Accordingly, Howell is currently focusing its 1999 capital 
investments on obligatory projects and pilot programs designed to build an 
inventory of projects for long-term

                                       14

<PAGE>

shareholder value. In the interim, should lower product prices be sustained, 
Howell may record a non-cash ceiling test impairment at the end of the first 
quarter 1999 to the value of its proved oil and gas properties as determined 
by Securities and Exchange Commission guidelines.

CRUDE OIL MARKETING & TRANSPORTATION

        There were no revenues or operating profits during 1998 or 1997 in 
the crude oil marketing and transportation segment as a result of the sale of 
the Business. Revenues and operating profits for 1996 were $666.1 million and 
$9.6 million, respectively. However, the Company did retain a direct and 
indirect interest in Genesis. As a result of the Company's interest, the 
Company recognized net earnings in Genesis of $0.6 million during 1998 and 
$0.9 million during 1997. See Note 5 of Notes to Consolidated Financial 
Statements.

        Effective December 3, 1996, the Company's sale of the assets and 
liabilities associated with crude oil marketing and transportation segment 
resulted in a pre-tax gain of $13.8 million recognized in other 
income/expense.

INTEREST EXPENSE

          During 1998, interest expense increased $9.3 million as a result of 
the increased short-term and long-term debt ("Debt") necessary for the 
Acquisition. Debt averaged $136.8 million during 1998. As a result of the 
sale of the fee mineral interests during December 1998, the Company was able 
to reduce this Debt by $13.0 million. In early 1999, the Company was able to 
further reduce Debt by $17.8 million as a result of the sale of the LaBarge 
properties and the buyout by SFC of its remaining excess EBITDA payments.

          Interest expense in 1997 decreased $5.3 million below the 1996 
level. The primary reason for this decrease was repayment of the term loan 
and revolving credit facilities out of funds received from: (i) the December 
3, 1996 sale of the Business to Genesis; (ii) the December 31, 1996 sale of 
100% of the outstanding common stock of Howell Transportation Services, Inc. 
to Lodestar Logistics, Inc.; and (iii) the July 31, 1997, sale of 
substantially all of the assets of the Company's research and reference fuels 
and custom chemical manufacturing business to SFC. Debt averaged $23.9 
million for the first half of 1997. The proceeds of the sale to SFC were used 
to reduce debt to an average of $11.8 million for the last half of the year 
before the Acquisition and an average of $21.0 million for the last half of 
the year including the Acquisition. The average debt during 1996 was $90.5 
million. The purchase of the Acqusition, increased debt to $137.0 million at 
year-end 1997. See Notes 3, 5 and 6 of Notes to Consolidated Financial 
Statements.

PROVISION FOR INCOME TAXES

         The Company's approximate effective tax rate of 35% reflects the 
statutory federal rate and state income taxes less the effect of statutory 
depletion deductions in excess of cost basis.

RESULTS FROM DISCONTINUED OPERATIONS

TECHNICAL FUELS AND CHEMICAL PROCESSING

         On July 31, 1997, Seller completed the sale of and disposition of 
substantially all of the assets of its research and reference fuels and 
custom chemical manufacturing business to SFC.

         As a result of the sale, the Company was entitled to receive an 
additional payment equal to 55% of the amount by which Buyer's "EBITDA" for 
each twelve month period ending June 30, 1998, 1999, 2000, 2001 and 2002 
exceeds the "Minimum EBITDA" (as defined in the agreement). The Minimum 
EBITDA amounts for those years were $5.0 million, $5.175 million, $5.35 
million, $5.525 million and 5.7 million, respectively, SFC was entitled to 
repurchase Seller's rights to these additional payments at any time after 
June 30, 1998, generally by paying to Seller an amount equal to the greater 
(a) the product obtained by multiplying the EBITDA payment amount for the 
immediately preceding twelve-month period by the number of twelve-month 
periods remaining, or (b) an amount fixed by the agreement, which was 
initially set at $5.7 million if the repurchase occurred during the 
twelve-month period ending on June 30, 1999, and which declines for each 
twelve-month period thereafter to $1.2 million if the repurchase occurred 
during the twelve-month period ending June 30, 2002.

         During August 1998, the Company received the first excess EBITDA 
payment of $0.7 million pre-tax. On January 4, 1999, SFC and Seller agreed 
that the amount fixed by the Agreement was not reasonable in light of the 
current performance; therefore, Seller agreed to reduce the excess EBITDA 
payment to $2.0 million which SFC agreed to purchase.

     The results of the technical fuels and chemical processing business have 
been classified as discontinued operations in the accompanying consolidated 
financial statements. Discontinued operations also includes the allocation of 
interest expense (based on a ratio of net assets of discontinued operations 
to total consolidated net assets). Allocated amounts are as follows:

LIQUIDITY AND CAPITAL RESOURCES

     RECENT EVENTS

     On January 4, 1999, the Company sold its right to participate in the 
future earnings of SFC for $2.0 million. SFC acquired the Company's research 
and reference fuel business in July 1997.

     On January 29, 1999, the Company sold its interest in the LaBarge field 
for $15.8 million.

     On March 16, 1999, the Company received a refund of $5.7 million for 
Federal taxes paid in prior years.

     On March 19, 1999, the Company signed an agreement to sell its interest 
in the Pitchfork and Grass Creek, Wyoming fields for $12.4 million.

     The cumulative proceeds from these events, totaling $35.9 million, have 
been or will be used to reduce bank debt. By utilizing this $35.9 million and 
part of the $5.9 million cash and cash equivalents available at December 31, 
1998, the Company will be able to pay off Tranche B and reduce Tranche A to 
approximately $84 million. See Item 2. "Properties" and Note 6 of Notes to 
Consolidated Financial Statements.

     CREDIT FACILITY

     The Company amended and restated the December 17, 1997 Credit Agreement 
effective on December 1, 1998 ("Credit Facility"). The Credit Facility is 
comprised of two tranches. Tranche A is a revolving credit facility with a 
termination date no later than December 15, 2002. The Borrowing Base was 
redetermined to $110 million prior to the 1998 sale of the Company's fee 
mineral interest, and to $105 million after the sale. Tranche B is a term 
loan with an amended borrowing availability of $30 million. The Company is 
required to pay commitment fees on the unused portion of Tranche A at a rate 
of 0.375% per annum while Tranche B is outstanding. After Tranche B has been 
repaid, the commitment fee will be based upon the Borrowing Base Utilization 
at a rate of 0.25% per annum if 25% or less of the Borrowing Base is used, 
0.30% if more than 25% and less than or equal to 75% is used, and 0.375% if 
more than 75% is used.

     Outstanding amounts under the Credit Facility bear interest, at the 
Company's option, at either the Eurodollar Loan ("Libor") rate per annum, or 
the Base Rate (prime), plus the Applicable Margin. The Applicable Margin is 
determined by the Borrowing Base Utilization Percentage. It ranges from as 
low as Libor plus 1.50% or the Base Rate plus 0.00% if 25% or less of the 
Borrowing Base is used, to as high as Libor plus 2.50% or the Base Rate plus 
0.75% if greater than 90% of the Borrowing Base is used.

     The Credit Facility is secured by mortgages on substantially all of the 
Company's oil and gas properties. The Credit Facility contains certain other 
affirmative and negative covenants, including limitations on the ability of 
the Company to incur additional debt, sell assets, merge or consolidate with 
other persons, pay dividends on its capital in excess of historical levels, 
and a prohibition on change of control or management. In addition, the Credit 
Facility requires the Company to maintain a ratio of current assets plus 
Tranche A borrowing capacity to current liabilities, excluding current 
maturities of long-term debt, of at least 1.0 to 1.0 and an interest coverage 
ratio of not less than 1.5 to 1.0 on a rolling four quarter basis through 
June 30, 1999, and beginning in the third quarter of 1999 and thereafter, of 
not less than 1.5 to 1.0 at the end of any fiscal quarter.

     On December 17, 1998, the Company was able to reduce the outstanding 
balance of Tranche A by $5 million and Tranche B by $8 million as a result of 
the sale of its fee mineral interests.

                                       16
<PAGE>

     As of December 31, 1998, the outstanding amounts under Tranche A bore 
interest at 8.0625% per annum on $102 million and under Tranche B bore 
interest at 10.5625% per annum on $22 million.

     OTHER

     At December 31, 1998, the Company had negative working capital of $11.4 
million, including the $22.0 million Tranche B loan facility referred to 
above. In 1998, cash provided from operating activities was $19.6 million.

     In 1993, the Company issued 690,000 shares of $3.50 convertible 
preferred stock. The net proceeds from the sale were $32.9 million. Dividends 
on the convertible preferred stock are to be paid quarterly. Such dividends 
accrue and are cumulative. The Company has paid all dividends on time. Due to 
the current market conditions, the Company's Board of Directors will evaluate 
on a quarterly basis whether or not to pay either common or preferred 
dividends.

     The Company currently anticipates spending approximately $0.1 million 
during fiscal years 1999 and 2000 at various facilities for capital and 
operating costs associated with ongoing environmental compliance and may 
continue to have expenditures in connection with environmental matters beyond 
fiscal year 1999. The Company spent $0.05 million on such expenditures in 
1998. See Note 10 of Notes to Consolidated Financial Statements.

     The Company believes that its cash flow from operations and amounts 
available under the Credit Facility will be sufficient to satisfy its current 
liquidity and capital expenditure requirements. At December 31, 1998, the 
Company had cash and cash equivalents of $5.9 million and $3 million 
available to it under the Credit Facility. A decline in the value of the 
Company's proved reserves could result in the bank reducing the Borrowing 
Base, thereby causing mandatory payments under the Credit Facility. While the 
Company does not expect this to happen in 1999, such payments would adversely 
affect the Company's ability to carry out its capital expenditure program and 
could cause the Company to recapitalize its debt through the public or 
private placement of securities. See "Recent Events".

     QUALITATIVE & QUANTITATIVE MATTERS

     In order to guarantee the Company a specific minimum sales price for its 
crude oil, the Company purchased a put option and sold a call option covering 
approximately 3,300 barrels per day of crude oil production for an 18-month 
period beginning March 1, 1995. The option strike prices were based on the 
average price of crude oil on the organized exchange with monthly settlement. 
The strike prices were $17 per barrel for the put option and $20 per barrel 
for the call option.

     During 1996, the monthly average sales price of crude oil on the 
organized exchange was between $17 and $20 per barrel for January and 
February; therefore, no options were exercised during the two months. The 
monthly average sales price for the remainder of the March 1, 1995 call 
option period, March 1996 through August 1996, was above the $20 ceiling. 
This resulted in collar payments of $0.9 million, excluding the premium 
amortization and were recorded as a reduction of revenue.

     Upon the expiration of the 18-month option period, the Company purchased 
a $16.50 per barrel put option and sold a $21.10 per barrel call option 
covering 100,000 barrels of oil per month for a six-month period ending 
February 28, 1997. For September through December 1996, the monthly average 
sales price exceeded the ceiling price. This resulted in collar payments for 
the four month period of $1.3 million which were recorded as a reduction of 
revenue.

     In 1997, the monthly average price of crude oil on the organized 
exchange exceeded the strike price for the call option during January and 
February, the final two months of the options. The payments required in 1997 
under the call option totaled $0.5 million and were recorded as a reduction 
of revenue.

     In 1998, the Company purchased a put option and sold a call option 
covering 4,800 barrels of oil per day for a nine-month period ended December 
31, 1998. The strike prices were $16.00 per barrel for the put option and 
$19.25 per barrel for the call option. There was no premium associated with 
these options. During 1998, the Company received $2.8 million as a result of 
the options. These amounts were recorded as additional revenues. Without the 
options the average price per barrel of oil for the year ended December 31, 
1998, would have been reduced from $11.37 to $10.55.

ACCOUNTING PRONOUNCEMENTS

     In June 1997, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards No. 130, "Reporting Comprehensive Income", 
("SFAS 130"). SFAS 130 is effective for periods beginning after December 15, 
1997. SFAS 130 establishes standards for reporting and displaying 
comprehensive income and its components. The purpose of reporting 
comprehensive income is to report a measure of all changes in equity of an 
enterprise that result from recognized transactions and other economic events 
of the period other than transactions with owners in their capacity as 
owners. In 1998, the Company adopted SFAS 130 and as of December 31, 1998, 
there were no adjustments to net income in deriving comprehensive income.

     In June 1997, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards No. 131, "Disclosures About Segments of an 
Enterprise and Related Information," ("SFAS 131"). SFAS 131 establishes 
standards for the way that public business enterprises report information 
about operating segments. SFAS 131 is effective for periods beginning after 
December 15, 1997. The Company has adopted SFAS 131. See Note 8 of Notes to 
the Consolidated Financial Statements.

     In June 1998, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards No. 133, "Accounting for Derivative 
Instruments and Hedging Activities," ("SFAS 133"). SFAS 133 establishes 
accounting and reporting standards for derivative instruments and hedging 
activities that require an entity to recognize all derivatives as an asset or 
liability measured at its fair value. Depending on the intended use of the 
derivative, changes in its fair value will be reported in the period of 
change as either a component of earnings or a component of other 
comprehensive income. SFAS 133 is effective for all fiscal quarters of fiscal 
years beginning after June 15, 1999. Earlier application of SFAS 133 is 
encouraged, but not prior to the beginning of any fiscal quarter that began 
after issuance of the Statement. Retroactive application to periods prior to 
adoption is not allowed. The Company has not quantified the impact of 
adoption of SFAS 133 on its financial statements.

YEAR 2000 DATE CONVERSION

     The Company has a plan in place that addresses the year 2000 ("Y2K") 
conversion issue. The first step in the plan was to evaluate all computer 
systems used in its operations. This includes accounting and financial 
systems, field and production systems, and other field or office devices that 
may not be Y2K compliant. This was followed by a determination of what 
remedial action is necessary and initiation of that remedy. The Company's 
plan to correct its in-house systems involved installation of new software 
and hardware. The Company installed a new accounting package during the 
fourth quarter of 1998 which is Y2K compliant. The Company has begun 
corrective action on major field systems and anticipates completion during 
the third quarter of 1999.

     The next step was to determine the Y2K status of relevant outside 
suppliers and vendors. While the Company cannot control the Y2K corrective 
action of third parties, it has begun the process of identifying and 
contacting its critical suppliers and vendors. Based on their status, the 
Company will develop contingency plans. These should be completed by the 
third quarter of 1999.

     Based on preliminary estimates, the cost of implementing this plan is 
approximately $300,000. It is not certain that this estimate is correct or 
that Year 2000 compliance can be achieved. The Company does not expect a 
significant disruption in its operations, but actual results could differ 
greatly from these expectations. Some areas that could cause differences to 
occur are the availability of personnel trained in this area, the ability to 
identify and correct all relevant computer code and non-compliant embedded 
systems and the degree of interdependence with third party suppliers and 
purchasers. Other areas outside the Company's control such as problems in the 
utility, banking, or transportation systems could have a material disruptive 
effect on the Company's ability to produce and deliver oil and gas, receive 
delivery of materials and supplies, or disburse or receive funds.

One example of a serious Y2K problem would be the shut down of a field which 
is on automated controls and/or a monitoring system. As disclosed above, the 
Company has examined such controls and systems in all of its major fields and 
is taking corrective action, as appropriate. Nevertheless, the Company 
intends to prepare a Y2K contingency plan which will address potential risks 
in the field, and possible solutions, including manual intervention or 
equipment replacement. The Company is unable to anticipate every potential 
problem and determine a contingency for every possible Y2K risk. Should 
essential services such as electricity be affected adversely, or if other Y2K 
related problems limit or restrict production from one of the Company's major 
fields, it could have a material adverse affect on the Company.

FORWARD-LOOKING STATEMENTS

Statements contained in this Report and other materials filed or to be filed 
by the Company with the Securities and Exchange Commission (as well as

                          INDEPENDENT AUDITORS' REPORT


To Howell Corporation:

   We have audited the accompanying consolidated  balance sheets of Howell  
Corporation and its subsidiaries as of December 31, 1998 and 1997, and the 
related consolidated statements of operations, changes in shareholders' 
equity, and cash flows for each of the three years in the period ended  
December 31, 1998.  These financial statements are the responsibility  of the 
Corporation's management.  Our responsibility is to express an opinion on 
these financial statements based on our audits.

   We conducted our audits in accordance with generally accepted auditing  
standards.  Those standards require that we plan and perform the audit to 
obtain reasonable assurance  about whether the financial statements are free 
of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.  
An audit also includes assessing the accounting  principles used and  
significant estimates made  by  management,  as  well as evaluating the  
overall financial statement presentation.  We believe that our audits provide 
a reasonable basis for our opinion.

   In our opinion, such consolidated financial statements present fairly,  in 
all material respects, the financial position of Howell Corporation and its 
subsidiaries at December 31, 1998 and 1997, and the results of their  
operations and their cash flows for each of the three years in the period 
ended December 31, 1998 in conformity with generally accepted accounting 
principles.

                        HOWELL CORPORATION AND SUBSIDIARIES

                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.   RECENT EVENTS

   On January 4, 1999, Howell Corporation and its subsidiaries (the 
"Company") sold its right to participate in the future earnings of Specified 
Fuels & Chemicals ("SFC") for $2.0 million.  SFC acquired the Company's 
research and reference fuel business in July 1997. 

   On January 29, 1999, the Company sold it interest in the LaBarge field for 
$15.8 million.

   On March 16, 1999, the Company received  a refund of $5.7 million for 
Federal taxes paid in prior years.

   On March 19, 1999, the Company signed an agreement to sell its interest in 
the Pitchfork and Grass Creek, Wyoming fields for $12.4 million.

   The cumulative proceeds from these events, totaling $35.9 million, have been 
or will be used to reduce bank debt.  By utilizing this $35.9 million and part 
of the $5.9 million cash and cash equivalents available at December 31, 1998, 
the Company will be able to pay off Tranche B and reduce Tranche A to 
approximately $84 million.  See Note 6.

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of  the 
Company. The Company accounts for its investment in less than 50% owned 
investees using the equity method of accounting when it has the ability to 
exercise significant influence over operating and financial policies of the 
investee.  All significant intercompany accounts and transactions have been 
eliminated.

     NATURE OF OPERATIONS

     The Company is primarily engaged in the exploration, production, 
acquisition and development of oil and gas properties. These operations are 
conducted in the United States.  The Company has also been involved in 
technical fuels and chemical processing and crude oil marketing and 
transportation, but has divested itself of these businesses.  The Company has 
retained an equity investment in a crude oil marketing and transportation 
company.   See Notes 3, 5, and 8.

     PROPERTY, DEPRECIATION, DEPLETION AND AMORTIZATION

     The Company follows the full-cost method of accounting for its oil and 
gas exploration and production activities, which are conducted solely in the 
United States.  Consequently, all costs pertaining to the acquisition, 
exploration and development of oil and gas reserves are capitalized and 
amortized using the unit-of-production method as the remaining proved oil and 
gas reserves are produced.  The Company's net investment in oil and gas 
properties is subject to a quarterly ceiling limitation calculation that is 
based on the present value of future net revenues from estimated production 
of proved oil and gas reserves valued at current prices.  Costs in excess of 
the ceiling limitation are currently charged to expense.  Gains or losses 
upon the disposition of a property, normally treated as an adjustment to 
capitalized costs, are recognized currently in the event of a sale of a 
significant portion (normally in excess of 25%) of oil and gas reserves.

     The costs allocated to the unproven properties and fee mineral interests 
of the Company are excluded from amortization using the full-cost method of 
accounting described above.  These costs are reviewed periodically for 
impairment.  This impairment will generally be based on geographic or 
geologic data.  At the time of any impairment, the related costs will be 
added to the costs being amortized under the full-cost method of accounting.  
Due to the perpetual nature of the Company's ownership of the mineral 
interests, the drilling of a well, whether successful or unsuccessful, may 
not represent a complete test of all depths of interest.  Therefore, at the 
time that a well is drilled only a portion of the costs allocated to the 
acreage drilled may be added to the costs being amortized.

                                       29

<PAGE>

     Other property and equipment are carried at cost.  Depreciation is 
provided principally using the straight-line method over the estimated useful 
lives of the assets.

     Maintenance and repairs are charged to expense as incurred, while 
renewals and betterments are capitalized.

     INCOME TAXES

     The Company utilizes a balance sheet liability approach in the 
calculation of the deferred tax balance at each financial statement date by 
applying the provisions of enacted tax laws to measure the deferred tax 
consequences of the differences in the tax and book bases of assets and 
liabilities as they result in net taxable or deductible amounts in future 
years.  The net taxable or deductible amounts in future years are adjusted 
for the effect of utilizing the carryback/carryforward attributes of any net 
losses generated and available tax credits.  Deferred tax assets are 
recognized if it is more likely than not that the future tax benefit will be 
realized.

     EARNINGS PER COMMON SHARE

     Basic earnings per common share amounts are calculated using the average 
number of common shares outstanding during each period.  Diluted earnings per 
share assumes conversion of dilutive convertible preferred stocks and 
exercise of all stock options having exercise prices less than the average 
market price of the common stock using the treasury stock method.  

     CONSOLIDATED STATEMENTS OF CASH FLOWS

     Included in the statements of cash flows are cash equivalents defined as 
short-term, highly liquid investments that are readily convertible to cash 
and so near to maturity that their value would not change significantly 
because of changes in interest rates.  The Company made cash payments for 
interest of $10,184,000, $1,347,000 and $7,793,000 in 1998, 1997 and 1996, 
respectively.  In 1998, 1997 and 1996, cash payments for income taxes totaled 
$261,000, $6,849,000, and $2,974,000, respectively.

     DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

     The Company estimates that the carrying amount of its cash and cash 
equivalents and accounts receivable and payable as reflected in its balance 
sheet approximates fair value.

     STOCK BASED COMPENSATION

     The intrinsic value method of accounting is used for stock-based 
employee compensation whereby no compensation expense is recognized when the 
exercise price of an employee stock option is equal to or greater than the 
market price of the Company's common stock on the grant date.

     ENVIRONMENTAL LIABILITIEs

     The Company provides for the estimated costs of environmental 
contingencies when liabilities are likely to occur and reasonable estimates 
can be made.  In accordance with full cost accounting rules, the Company 
provides for future environmental clean-up costs associated with oil and gas 
activities as a component of its depreciation, depletion and amortization 
expense.  Information regarding environmental liabilities can be found in 
Note 10.  Ongoing environmental compliance costs, including maintenance and 
monitoring costs, are charged to expense as incurred.

     DERIVATIVES

     In order to mitigate the effects of future price fluctuations, the 
Company has used a limited program of hedging its crude oil production.  
Crude oil futures and options contracts are used as the hedging tools.  
Changes in the market value of the futures transactions are deferred until 
the gain or loss is recognized on the hedged transactions.

     In 1995, the Company purchased a put option and sold a call option 
covering 3,300 barrels per day of oil production for an 18-month period 
beginning March 1, 1995.  The option strike prices were based on the average 
price of crude oil on the organized exchange, with monthly settlement.  The 
strike prices were $17 per barrel for the put option and $20 per barrel for 
the call option.  The premiums for the options were amortized over the option 
period.  Upon expiration of the 18-month option period, the Company purchased 
a put option and sold a call option covering 100,000 barrels of oil per month 
for a six-month period ended February 28, 1997.  The strike 

                                       30

<PAGE>

prices were $16.50 per barrel for the put option and $21.10 per barrel for 
the call option.  There was no premium associated with these options. 

     During 1996, the monthly average price of crude oil on the organized 
exchange exceeded the strike price for the call option in ten months.  The 
payments required in 1996 under the call options and the premium amortized in 
1996 totaled $2.5 million and were recorded as a reduction of revenue.  
During 1995, the monthly average price of crude oil on the organized exchange 
was between $17 and $20 per barrel; therefore, none of the options were 
exercised during this period.  Premiums amortized during 1995 totaled $0.4 
million and were recorded as a reduction of revenue. 

     In 1997, the monthly average price of crude oil on the organized 
exchange exceeded the strike price for the call option during January and 
February, the final two months of the options.  The payments required in 1997 
under the call option totaled $0.5 million and were recorded as a reduction 
of revenue.

     In 1998, the Company purchased a put option and sold a call option 
covering 4,800 barrels of oil per day for a nine-month period ended December 
31, 1998. The strike prices were $16.00 per barrel for the put option and 
$19.25 per barrel for the call option.  There was no premium associated with 
these options. During 1998, the Company received $2.8 million as a result of 
the options. These amounts were recorded as additional revenues.  Without the 
options the average price per barrel of oil for the year ended December 31, 
1998, would have been reduced from $11.37 to $10.55.

   Crude oil future contracts and options were also used as a hedging tool in 
a limited program of hedging crude oil inventories and fixed purchase price 
commitments.  Other costs and expenses related to the crude oil marketing and 
transportation businesses were reduced by $0.1 million in 1996 from the 
effects of futures and options.

     REVENUE RECOGNITION

     The Company recognizes oil and gas revenue from its interests in 
producing wells as oil and gas is sold from those wells.  Oil and gas sold in 
production operations is not significantly different from the Company's share 
of production.

     The Company utilizes the sales method to account for gas production 
volume imbalances.  Under this method, income is recorded based on the 
Company's net revenue interest in production taken for delivery.  Management 
does not believe that the Company had any material gas imbalances at December 
31, 1998 or 1997.

     CONCENTRATION OF RISK

     Substantially all of the Company's accounts receivable result from oil 
and gas sales and joint interest billings to third parties in the oil and gas 
industry.  This concentration of customers and joint owners may impact the 
Company's overall credit risk in that these entities may be similarly 
affected by changes in economic and other conditions.

     USE OF ESTIMATES

     The preparation of financial statements in conformity with generally 
accepted accounting principles requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities and 
disclosure of contingent assets and liabilities at the date of the financial 
statements and the reported amounts of revenues and expenses during the 
reporting period.  Actual results could differ from those estimates.

     RECLASSIFICATIONS

     Certain reclassifications have been made to the 1997 and 1996 financial 
presentation to conform with the 1998 presentation.  Other revenues and 
expenses includes all of the revenues, costs and expenses (operating expenses,
depreciation, selling, general and administrative expenses) associated with 
the crude oil gathering and marketing operations, pipeline operations and 
transportation services.  

NOTE 3. ACQUISITIONS & DISPOSITIONS

1998

   On December 17, 1998, the Company sold its fee mineral estates and royalty 
interests comprised of approximately 875,000 acres located in the states of 
Alabama, Mississippi, and Louisiana for $13.0 million.  The 

                                       31

<PAGE>

company will retain a 10% net profits interest after payout.  The net daily 
production attributable to these assets is approximately 350 BOE.  Proceeds 
from the sale were used to retire bank debt.  See Note 6.

   During November 1998, the Company announced the execution of a letter 
agreement with SFC which purchased the Company's research and reference fuel 
business on July 31, 1997.  As part of the consideration in that sale, the 
Company was to receive an additional payment equal to 55% of the amount by 
which SFC's "EBITDA" for each twelve-month period ending June 30, 1998, 1999, 
2000, 2001 and 2002 exceeds the "Minimum EBITDA" (as defined in the 
Agreement).  The Minimum EBITDA amounts for those years were $5.0 million, 
$5.175 million, $5.35 million, $5.525 million and $5.7 million, respectively. 
 The Company received $0.7 million pre-tax under that provision in 1998.  On 
January 4, 1999, SFC and Howell Hydrocarbons & Chemicals, Inc. ("Seller"), a 
wholly owned subsidiary of the Company, agreed that the amount fixed by the 
Agreement was not reasonable in light of the current performance; therefore, 
Seller agreed to reduce the excess EBITDA payment to $2.0 million which SFC 
agreed to purchase.

     Effective May 22, 1998, Howell Petroleum Corporation ("HPC"), a wholly 
owned subsidiary of Howell Corporation, entered into a Settlement Agreement 
and Release with Amoco Production Company ("Amoco") and Snyder Oil 
Corporation ("SOCO") whereby the parties agreed to settle the pending 
litigation between them styled:  SNYDER OIL CORPORATION, PLAINTIFF V. AMOCO 
PRODUCTION COMPANY AND HOWELL PETROLEUM CORPORATION, DEFENDANTS in the 
District Court, Ninth Judicial District, Civil Action No. 29861, Fremont 
County, Wyoming.  Under the terms of the settlement, HPC agreed to relinquish 
its contractual rights to purchase that portion of the Amoco Wyoming package 
relating to the Beaver Creek Unit and the associated facilities.  In 
addition, Amoco agreed to sell HPC an approximate 31% working interest in the 
Higgins Unit located in Sweetwater County, Wyoming, and a 1.95% overriding 
royalty interest covering over 78,000 acres in the Natural Buttes Field 
located in Uintah County, Utah.  The purchase price for these predominately 
gas properties was $11 million.  HPC's in-house petroleum engineers estimate 
total proved reserves attributable to these properties were 8.1 BCFE.  Net 
daily production from the properties was approximately 1.8 MMCF of natural 
gas with a projected reserve-to-production index of 12 years.  This 
settlement completed HPC's acquisition of the properties from Amoco.  HPC 
purchased proved reserves of 39.1 MMBOE for $126.4 million which was an 
acquisition cost of $3.23 per barrel of oil equivalent. The operating results 
of the assets acquired from Amoco have been included in the Company's 
Statement of Operations since May 22, 1998.  Pro forma information is not 
required because of materiality.  

1997

   On December 18, 1997, the Company purchased certain oil and gas producing 
properties (the "Package") in Wyoming from Amoco Production Company 
("Amoco"), a subsidiary of Amoco Corporation, for approximately $115.4 
million, subject to purchase price adjustments.  The effective date of the 
Purchase was December 1, 1997.  The Package was accounted for using the 
purchase method of accounting, and accordingly, the purchase price was 
allocated to the assets acquired based on estimated fair values at the date 
of acquisition.  The operating results of the assets acquired from Amoco have 
been included in the Company's Statement of Operations since December 18, 
1997.  The pro forma information shown below assumes that the Purchase 
occurred at January 1, 1997.  Adjustments have been made to reflect changes 
in the Company's results from revenues and direct operating expenses of the 
producing properties acquired from Amoco, additional interest expense to 
reflect the acquisition, depreciation, depletion and amortization based on 
fair values assigned to the assets acquired, and general and administrative 
expenses incurred from hiring additional employees.  The pro forma financial 
data are based on assumptions and the actual recording of the Purchase could 
differ.  The unaudited pro forma financial data are not necessarily 
indicative of financial results that would have occurred had the Acquisition 
occurred on January 1, 1997, and should not be viewed as indicative of 
operations in future periods.

     On October 1, 1997, the Company acquired Voyager Energy Corp. 
("Voyager"), an oil and gas exploration and production company, for 352,638 
shares of common stock of the Company in a tax-free reorganization.  The 
shares issued by the Company in the merger represent in the aggregate 
approximately 6.5 percent  of the Company's common stock outstanding after 
the transaction.  The value of the shares in the tax-free reorganization was 
$4.6 million.  The shares were distributed as a non-cash transaction and, as 
such, are not reflected in the Consolidated Statement of Cash Flows for the 
year ended December 31, 1997.  The Company assumed approximately $1.3 million 
in Voyager indebtedness as a result of the merger.

   On July 31, 1997, the Seller completed the previously announced sale and 
disposition of substantially all of the assets of its research and reference 
fuels and custom chemical manufacturing business to SFC.

   The assets purchased by SFC included the fee property in Channelview, 
Texas, on which Seller's refinery was located, all refining facilities 
located on the fee property and all related personal property, all 
inventories of finished products, work in process, raw materials and supplies 
related to the business, substantially all of the accounts receivable on the 
closing date, all transferable intellectual property used primarily in the 
business and all of Seller's rights under various contracts and leases 
related to the business.  In connection with the transaction, (a) SFC 
received a license to use the name "Howell Hydrocarbons & Chemicals" for a 
five-year period after closing and assumed certain obligations of Seller and 
the Company, and (b) the Company agreed not to engage (directly or through 
affiliates) in any competing business for a five-year period after the 
closing. 

   The sale resulted in a pre-tax gain of $0.4 million and the proceeds of 
the sale were used by the Company to reduce its outstanding indebtedness.  
The sale completes the divestiture by the Company of all of its 
non-exploration and production businesses.  In connection with the sale, the 
Company has given and received environmental and other indemnities.  Should 
claims be made against the Company based on these indemnities, the Company 
could be required to perform its obligations thereunder.

   In consideration of the assets sold to SFC, Seller and the Company 
received a payment of $19.8 million in cash, which included $14.8 million for 
the property, plant, equipment and related items, and $5.0 million in payment 
of working capital items.  Seller was entitled to receive an additional 
payment equal to 55% of the amount by which Buyer's "EBITDA" for each twelve 
month period ending June 30, 1998, 1999, 2000, 2001 and 2002 exceeded the 
"Minimum EBITDA". 

   The results of the technical fuels and chemical processing business have 
been classified as discontinued operations in the accompanying consolidated 
financial statements.  Discontinued operations also includes the allocation 
of interest expense (based on a ratio of net assets of discontinued 
operations to total consolidated net assets).  Allocated amounts are as

1996

   On December 31, 1996, the Company sold 100% of the outstanding common 
stock of Howell Transportation Services, Inc. ("HTS") to Lodestar Logistics, 
Inc. ("Lodestar") for $2.6 million, consisting of $1.8 million in cash, a 
$0.5 million note receivable and a $0.3 million receivable in the form of 
services to be rendered by HTS for Seller.  Lodestar is owned by the former 
president of HTS, and the Company believes the sale price was equivalent to 
an arm's-length transaction.

   The $0.5 million non-revolving note bears interest at the Prime Rate for a
term of no longer than 84 months. 

   The note receivable and the receivable for future services are non-cash 
transactions which are not reflected in the statement of cash flows for the 
year ended December 31, 1996.

These assets consisted of the crude oil gathering and marketing operations 
and pipeline operations of Howell ("Business").

     Buyer was formed by MLP and LLC to acquire the Business from Howell and 
similar assets from Basis.  MLP is owned 98% by limited partners and 2% by 
LLC, which is the general partner.  LLC is owned 46% by Howell and 54% by 
Basis.  As a result of this transaction, Howell owns a subordinated limited 
partner interest in Buyer of 9.01%, a direct general partner interest in 
Buyer of 0.18% and a general partner interest through MLP of 0.74% of Buyer.

     In accordance with the Agreement, Howell received cash of approximately 
$74.0 million and 991,300 subordinated limited partner units in Buyer in 
exchange for its sale and conveyance of the Business and recognized a gain in 
the amount of approximately $13.8 million.  The receipt of units is a 
non-cash transaction which reduced property, plant and equipment and 
increased investment in Genesis.  Since this was non-cash, it is not 
reflected in the statement of cash flows for the year ended December 31, 
1996.  Except as specifically provided in the Agreement, Howell retained all 
liabilities related to the Business arising from the operations, activities 
and transactions of the Business up through the closing date, including 
various environmental-related liabilities.  Howell made various 
representations and warranties as to itself and the Business and has agreed 
to indemnify Buyer for any breaches thereof. Claims for breaches of such 
representations and warranties must be brought before December 3, 2001.  
Howell  also agreed to perform, and retain the liability for, the cleaning of 
certain tanks used in the pipeline operations which cleaning was completed in 
1997.

     On the closing date, Howell entered into various agreements with Buyer, 
MLP and LLC pursuant to the Agreement, including (a) a non-competition 
agreement prohibiting Howell from competing with the Business for a period of 
ten years; (b) an agreement relating to the purchase of crude oil by Howell 
for use in its technical fuels business and the sale of crude oil by Howell 
from its oil and gas exploration and production business; (c) an agreement 
whereby Howell will provide certain transitional services to Buyer; (d) an 
agreement whereby MLP will sell additional limited partner units to the 
public and use the proceeds to redeem the subordinated limited partner units 
in Buyer owned by Howell after certain conditions are met; and (e) an 
agreement whereby one-half of the subordinated limited partner units owned by 
Howell are pledged to secure Howell's indemnification of Buyer for 
environmental liabilities.

     Also at closing, Howell entered into an agreement with Salomon which 
provides (a) an unconditional obligation of Howell to buy its 46% share of 
additional limited partner interests ("APIs") from Salomon if Howell (as a 
member of LLC) has approved an acquisition by Buyer and (b) to the extent 
APIs are outstanding, an obligation by Howell to purchase 46% of such 
outstanding APIs, but only to the extent of any distribution made to Howell 
by Buyer on Howell's subordinated limited partner units.

Summarized financial information for the Buyer for the years ended December 
31, 1998 and 1997, respectively, was as follows:

     At December 31, 1998, the amount of investment in the Buyer includes 
goodwill in the amount of $4.9 million which is being amortized over a period 
of 20 years.  Accumulated amortization at December 31, 1998, was $0.5 million.

     Salomon has reported that on May 1, 1997, it sold the stock of Basis to 
Valero Energy Corporation ("Valero").  On May 1, 1997, Basis informed  the 
Company that Basis intends to transfer its interest in LLC back to Salomon.  
Pursuant to the agreement forming LLC, the Company had 30 days from the date 
of receipt of such 

                                       35

notice to make an offer for  Basis' interest in LLC.  The Company decided not 
to make an offer to purchase Basis' interest in LLC.

     Basis is party to a number of agreements with Genesis, some of which may 
have terminated in connection with the transfer to Valero and others which 
may be terminated by Basis pursuant to their terms.  Whether such contracts 
will be terminated or revised by Basis and/or Genesis in the future and the 
ultimate effect on Genesis of any such termination or revision cannot be 
determined at this time, but may or may not have a material effect on Howell.

     On July 29, 1997, the Board of Directors of LLC cancelled the $3.45  
million note payable by Howell Crude Oil Company ("HCO") to LLC. The note was 
distributed to HCO as a non-cash transaction and, as such, is not reflected 
in the Consolidated Statement of Cash Flows for the year ended December 31, 
1998.

     The Company had no capital lease obligations.

     REVOLVING CREDIT/TERM LOAN AGREEMENT

   The Company amended and restated the December 17, 1997 Credit Agreement 
effective on December 1, 1998 ("Credit Facility").  The Credit Facility is 
comprised of two tranches.  Tranche A is a revolving credit facility with a 
termination date no later than December 15, 2002. The Borrowing Base was 
redetermined to $110 million prior to the 1998 sale of the Company's fee 
mineral interest, and to $105 million after the sale.  Tranche B is a term 
loan with an amended borrowing availability of $30 million.  The Company is 
required to pay commitment fees on the unused portion of Tranche A at a rate 
of 0.375% per annum while Tranche B is outstanding.  After Tranche B has been 
repaid, the commitment fee will be based upon the Borrowing Base Utilization 
at a rate of 0.25% per annum if 25% or less of the Borrowing Base is used, 
0.30% if more than 25% and less than or equal to 75% is used, and 0.375% if 
more than 75% is used.

   Outstanding amounts under the Credit Facility bear interest, at the 
Company's option, at either the Eurodollar Loan ("Libor") rate per annum, or 
the Base Rate (prime), plus the Applicable Margin.  The Applicable Margin is 
determined by the Borrowing Base Utilization Percentage.  It ranges from as 
low as Libor plus 1.50% or the Base Rate plus .00% if 25% or less of the 
Borrowing Base is used, to as high as Libor plus 2.50% or the Base Rate plus 
 .75% if greater than 90% of the Borrowing Base is used.

   The Credit Facility is secured by mortgages on substantially all of the 
Company's oil and gas properties.  The Credit Facility contains certain other 
affirmative and negative covenants, including limitations on the ability of 
the Company to incur additional debt, sell assets, merge or consolidate with 
other persons, pay dividends on its capital in excess of historical levels, 
and a prohibition on change of control or management.  In addition, the 
Credit Facility requires the Company to maintain a ratio of current assets 
plus Tranche A borrowing capacity to current liabilities, excluding current 
maturities of long-term debt, of at least 1.0 to 1.0 and an interest coverage 
ratio of not less than 1.5 to 1.0 on a rolling four quarter basis through 
June 30, 1999, and beginning in the third quarter of 1999 and thereafter, of 
not less than 1.5 to 1.0 at the end of any fiscal quarter.

   On December 17, 1998, the Company was able to reduce the outstanding 
balance of Tranche A by $5 million and Tranche B by $8 million as a result of 
the sale of its fee mineral interest.  See Note 3.

   As of December 31, 1998, the Tranche A interest rate was 8.0625% per annum 
on $102 million and the Tranche B interest rate was 10.5625% per annum on $22 
million.

                                       36

<PAGE>

   At December 31, 1998, the Company had cash and cash equivalents of $5.9 
million and $3 million available to it under the Credit Facility.  Should a 
decline in the value of the Company's proved reserves occur during 1999, the 
bank could reduce the Borrowing Base, thereby causing mandatory payments 
under the Credit Facility.  While the Company does not expect this to happen 
in 1999, such payments would adversely affect the Company's ability to carry 
out its capital expenditure program and could cause the Company to accelerate 
its plans to recapitalize its debt through the public or private placement of 
securities. See Note 1 "Recent Events" for proceeds received in 1999 applied 
to reduce the outstanding borrowing under the Credit Facility.

The fair value of the Company's long-term debt at December 31, 1998 and 1997, 
was estimated to be the same as its carrying value in the balance sheet since 
all significant debt obligations bear interest at floating market rates. 

NOTE 7.  SHAREHOLDERS' EQUITY

     PREFERRED STOCK

     At December 31, 1998 and 1997, the Company had 3,000,000 shares of 
preferred stock authorized.

     In April 1993, the Company completed a public offering of 690,000 shares 
of $3.50 convertible preferred stock.  The offering was priced at $50 per 
share to yield 7%.  The convertible preferred stock is convertible into 
common stock of the Company at the option of the holder, at any time, at a 
conversion rate equal to, approximately, 3.03 common shares for each 
preferred share, with fractional shares paid in cash.  The Company has the 
option to redeem the convertible preferred stock at a declining premium 
redemption price beginning in 1996.

     Dividends on the convertible preferred stock are to be paid quarterly. 
Such dividends accrue and are cumulative.  Holders of the preferred stock 
have no voting rights except on matters affecting the rights of preferred 
shareholders.  If at any time the equivalent of six quarterly dividends 
payable on the preferred stock are accrued and unpaid, the preferred 
shareholders will be entitled to elect two additional directors to the 
Company's Board of Directors.  The Company is current in the payment of 
preferred dividends.

     COMMON STOCK

     At December 31, 1998 and 1997, the Company had 50,000,000 shares of 
common stock authorized.

     EMPLOYEE STOCK OPTIONS

     The Company maintains nonqualified stock option plans that provide for 
granting of options for the purchase of common stock to key employees.  These 
stock options may be granted for periods up to 10 years and are generally 
subject to vesting up to four years.  At December 31, 1998, no shares were 
available for future option grants.

     Stock option activity for the Company during 1998, 1997, and 1996 was as

   In addition to the results of the Company's oil and gas exploration and 
production activities, the oil and gas production segment information 
includes the gas marketing activities of the Company and the results of sales 
of production of carbon dioxide, helium and sulfur from the LaBarge Project.

   Inter-segment sales by the oil and gas production segment to the crude oil 
marketing and transportation segment were $0, $0 and $15,438 in 1998, 1997 
and 1996, respectively.  These amounts have been eliminated in consolidation.

   Marathon Oil Company, a customer of the crude oil marketing and 
transportation segment, accounted for approximately 18% of consolidated 
revenues in 1996.

   As a result of the sale in 1997 to SFC, referred to in Note 3, segment 
data for 1996 have been restated to conform to the 1998 presentation.

   NOTE 9.  LITIGATION

   On July 11, 1995, the Company received a demand letter from several 
working interest owners in the North Frisco City Field and in the North Rome 
Field indicating the Company had not paid according to the terms of a "call 
on production."  The Company was granted a call on a portion of this 
production but never exercised the call.  Accordingly, the Company has filed 
petitions for declaratory judgment to that effect in cases styled HOWELL 
PETROLEUM CORPORATION, ET AL, VS. SHORE OIL COMPANY, ET AL, District Court of 
Harris County, Texas; No. 95-037480 and HOWELL PETROLEUM CORPORATION, ET AL, 
VS. TENEXCO, INC., ET AL, District Court of Harris County, Texas; No. 
95-037970. The defendants in this action have counterclaimed against the 
Company.  These claims are similar in nature to the Alabama and Mississippi 
royalty litigation. One of the defendants, John Faulkinberry, has filed a 
counterclaim against the Company seeking actual damages of $75,000 and 
punitive damages of $100,000,000. Effective July 14, 1997, the Company 
settled with John Faulkinberry as well as several other working interest 
owners.  The terms of the settlement are confidential, but the amounts paid 
in settlement were not material to the Company's financial condition, results 
of operations or cash flows.  The case (as to the remaining interest owners) 
was tried during the week of December 7, 1998.  On January 6, 1999 the trial 
court granted the request of the Company's subsidiaries for a declaratory 
judgment. The trial court ruled that neither of the Company's subsidiaries 
had exercised the call and denied the defendants' counterclaim for monetary 
damages.  The trial court also awarded the subsidiaries attorney fees of 
$373,333, plus 10% interest on all sums owing to the subsidiaries.  
Subsequently, this case was settled.

   Related to this matter, several royalty owners have filed lawsuits against 
the Company in Alabama and Mississippi concerning pricing in the North Frisco 
City Field.  The lawsuits allege the Company violated its contracts with the 
plaintiffs by not paying the plaintiffs ". . . the highest available price 
for oil."  Damages claimed by the plaintiffs include approximately $3.8 
million and are based on numerous damage theories including, but not limited 
to, allegations of breach of contract and fraud.  The complaints also seek 
unspecified punitive damages in the Alabama lawsuits and $7 million in 
punitive damages in the Mississippi lawsuit.  The Company filed answers 
denying all charges.  The Company does not believe that the ultimate 
resolution of these matters will have a materially adverse effect on the 
financial position, results of operations or cash flows of the Company. On 
July 28, 1997, the Company settled the Mississippi lawsuit.  On March 30, 
1998 a tentative settlement was reached with the Alabama Class 
representative.  On February 24, 1999 the trial court entered a preliminary 
approval order.  The final fairness hearing is scheduled for May 5, 1999.  
The amounts paid in settlement of both cases were not material to the 
Company's financial condition, results of operations or cash flows.

   There are various other lawsuits and claims against the Company, none of 
which, in the opinion of management, will have a materially adverse effect on 
the Company.

NOTE 10.  COMMITMENTS AND CONTINGENCIES

   The Company is subject to various environmental regulations and laws. 
Procedures exist within the Company to monitor compliance and assess the 
potential environmental exposure of the Company.  The Company believes that 
such exposure is not materially adverse to its financial position, results of 
operations or cash flows.

   The Company has indemnified Exxon for certain environmental claims that 
may be made in the future attributable to the time when Exxon owned the crude 
oil pipelines that the Company acquired from Exxon.  In 1996, the crude oil 
pipelines were acquired by Buyer under the Agreement, however, the Company 
retained certain environmental liabilities which management believes will not 
have a material financial impact on the financial position, results of 
operations or cash flows of the Company.  See Note 5.

   The Channelview facility was discharging wastewater pursuant to a state 
wastewater discharge permit.  Industries located in the state of Texas are 
required to obtain wastewater discharge permits from the state and from the 
Environmental Protection Agency ("EPA").  When the Company purchased the 
Channelview facility in 1988, it requested and obtained a transfer of these 
permits.  In 1990, the Company applied for a renewal of both the federal and 
the state wastewater permits.  The state permit was reissued in 1992.  During 
1993, the Company determined that the federal wastewater discharge permit may 
have expired prior to the EPA's transfer of the permit to the Company.  The 
EPA has been contacted to resolve this issue, and the Company has been 
negotiating to obtain a renewed permit.  Penalties may potentially be imposed 
upon the Company as a result of this matter; however, until this matter is 
resolved, the amount of such penalties, if any, cannot be quantified.  While 
penalties may be material and the actions of regulatory bodies are not 
subject to accurate prediction, based on information currently available to 
the Company and on the circumstances present at its Channelview facility 
(including the existence of the state permit, the Company's compliance with 
the more stringent state permit, and the ability, if required, to operate the 
Channelview facility utilizing holding tanks and offsite third party 
treatment facilities in the absence of a permit), the Company does not 
believe that this matter will have a materially adverse effect on the 
financial position, results of operations or cash flows of the Company.  In 
1997, the Channelview facility was sold to SFC, however, the Company retained 
certain environmental liabilities for a period of five years which management 
believes will not have a material financial impact on the financial position, 
results of operations or cash flows of the Company.

   The Company has indemnified Amoco for all third party claims other than 
those for which Amoco is obligated to indemnify the Company regardless of 
whether the claims relate to periods of time prior to or after the closing.  
Amoco has indemnified the Company for non-environmental third party claims 
relating to the period of time prior to closing that are identified within 
eighteen months after closing if the claims exceed three percent of the 
purchase price in the aggregate.  Amoco also will indemnify the Company for 
environmental third party claims relating to the period of time prior to 
closing that are identified within twelve months after closing if the claims 
exceed three percent of the purchase price in the aggregate but in no event 
to exceed 50% of the purchase price. 

   Under the terms of the purchase agreement, Amoco has a call on certain oil 
production from the properties acquired in the Acquisition.  Beginning March 
1, 1998, for a fifteen year period Amoco has a call, if exercised, on 4,000 
barrels per day of sweet crude oil production net to the Company's interest 
from the acquired Salt Creek field at a price per barrel equal to the average 
of three postings chosen by the Company from an approved group plus $1.50; 
provided, however, the maximum price paid shall not exceed Platt's Wyoming 
Sweet Monthly Average and the minimum price paid shall not be less than  
Platt's Wyoming Sweet Monthly Average minus $1.00.  Beginning March 1, 1998, 
for a seven year period Amoco has a call on 2,000 barrels per day of sour 
crude oil production net to the Company's interest from the acquired Elk 
Basin field and all of the sour crude oil production from the acquired Grass 
Creek and Pitchfork fields at a price per barrel equal to the average of 
three postings chosen by the Company from an approved group plus $0.25; 
provided, however, the maximum price paid shall not exceed Platt's Wyoming 
Sweet Monthly Average minus $2.75 and the minimum price paid shall not be 
less than Platt's Wyoming Sweet Monthly Average minus $4.75.  All crude oil 
pricing is subject to gravity adjustment. 

   The Company occupies office and operational facilities and uses equipment 
under operating lease arrangements.  Expense of these arrangements amounted 
to $425,000 in 1998, $425,000 in 1997 and $2,765,000 in 1996.  At December 
31, 1998, long-term commitments for lease of facilities and equipment totaled 
approximately $4,207,000, consisting of $651,000, $672,000, $672,000, 
$672,000 and $672,000 for the years 1999 through 2003, respectively, and 
$868,000 thereafter.

     Note: Because diluted EPS from continuing operations increases from 
$(12.84) to $(12.74) when common stock options are included in the 
computation and because diluted EPS increases from $(12.74) to $(8.92) when 
convertible preferred shares are included in the computation, those common 
stock options and convertible preferred shares are antidilutive and are 
ignored in the computation of diluted EPS from continuing operations. 
Therefore, diluted EPS from continuing operations is reported as $(12.84).

Therefore, diluted EPS from continuing operations is reported as $0.17.

NOTE 12.   SUPPLEMENTARY OIL AND GAS PRODUCING INFORMATION (UNAUDITED)

     RECENT EVENTS

The proposed sale of the Pitchfork and Grass Creek, Wyoming fields and the 
actual sale of LaBarge, Wyoming fields for a total of $28.2 million represent
7.0 million barrels of oil equivalent ("MMBOE") out of the 43.1 MMBOE of the 
Company's proved oil and gas reserves at December 31, 1998 and approximately 
2.2 MBOE per day of the Company's 11.9 MBOE 1998 daily production. These 
transactions also represent 460 gross and 135 net oil wells, 21 gross and 9 
net gas wells, 10,409 gross and 2,508 net developed acres, and 320 gross and 
320 net undeveloped acres.

     RESERVES

     The Company's net proved reserves of crude oil, condensate and natural 
gas liquids (referred to herein collectively as "oil") and its net proved 
reserves of gas have been estimated by the Company's engineers in accordance 
with guidelines established by the Securities and Exchange Commission. The 
reserve estimates, except for the reserves purchased from Amoco, at December 
31, 1998, 1997, and 1996, were reviewed by independent petroleum consultants,
H. J. Gruy and Associates, Inc. The December 31, 1998 and 1997 reserves, 
associated with the Wyoming properties acquired from Amoco, were reviewed by 
independent petroleum consultants, Ryder Scott & Associates. The estimates 
for 1995 were reviewed by L. A. Martin & Associates, Inc. These estimates 
were used in the computation of depreciation, depletion and amortization 
included in the Company's consolidated financial statements and for other 
reporting purposes.

</TABLE>
     Total proved reserves at year-end 1998 were 43,072 MBOE compared to 
56,109 MBOE at year-end 1997. This change was related almost entirely to 
downward revisions associated with lower oil and gas prices. The price 
sensitivity of the Company's reserve base is illustrated by the fact that if 
year-end 1998 reserves were calculated using year-end 1997 pricing, total 
proved reserves would have remained basically unchanged at 1997 reserve levels.

     Proved oil reserves at December 31, 1998, include 1.4 million barrels of 
natural gas liquids ("NGL").

     In addition to the oil and gas reserves shown above, the Company, through
its participation in the LaBarge Project in southwestern Wyoming, had proved 
carbon dioxide reserves of 57,140 MMCF and proved helium reserves of 2,570 
MMCF at December 31, 1998. The LaBarge Project was sold in January 1999.

     STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO 
PROVED OIL AND GAS RESERVES. The accompanying table presents a standardized 
measure of discounted future net cash flows relating to the production of the 
Company's estimated proved oil and gas reserves at the end of 1998 and 1997. 
The method of calculating the standardized measure of discounted future net 
cash flows is as follows:

        (1) Future cash inflows are computed by applying year-end prices of oil
        and gas to the Company's year-end quantities of proved oil and gas
        reserves. Future price changes are considered only to the extent
        provided by contractual arrangements in existence at year-end.

        (2) Future development and production costs are estimates of
        expenditures to be incurred in developing and producing the proved oil
        and gas reserves at year-end, based on year-end costs and assuming
        continuation of existing economic conditions.

                                       45

<PAGE>

        (3) Future income tax expenses are calculated by applying the applicable
        statutory federal income tax rate to future pretax net cash flows.
        Future income tax expenses reflect the permanent differences, tax
        credits and allowances related to the Company's oil and gas producing
        activities included in the Company's consolidated income tax expense.

        (4) The discount, calculated at ten percent per year, reflects an
        estimate of the timing of future net cash flows to give effect to the
        time value of money.

        The standardized measure is not intended to represent the market 
value of reserves and, in view of the uncertainties involved in the reserve 
estimation process, including the instability of energy markets as evidenced 
by recent declines in both natural gas and crude oil prices, the reserves may 
be subject to material future revisions.

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

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,

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

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

                     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-
<PAGE>

                  (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-
<PAGE>

                  (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.

                                 ARTICLE III

                       REPRESENTATIONS AND WARRANTIES

         3.1. REPRESENTATIONS AND WARRANTIES OF VOYAGER. Voyager hereby 
represents and warrants to Howell and Newco that, as of the date hereof:

                  (a) CORPORATE ORGANIZATION AND QUALIFICATION. Voyager is a 
corporation duly organized, validly existing and in good standing under the 
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 
operated, or the business conducted, by it require such qualification, except 
where any failure to be so qualified or in good standing would not have a 
material adverse effect on the financial condition, properties, businesses or 
results of operations of Voyager (a "Material Adverse Effect"). The 
Disclosure Letter (as defined below) lists all jurisdictions in which Voyager 
is qualified to do business as a foreign corporation. Voyager has the 
corporate power and authority to carry on its businesses as they are now 
being conducted. Except as set forth in the Disclosure Letter, Voyager does 
not own, directly or indirectly, any interest in any corporation, partnership 
or other entity. As used herein, the "Disclosure Letter" is the letter 
delivered by Voyager to Howell as of the date of this Agreement containing 
disclosures related to the representations and warranties contained in this 
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 
Voyager Preferred Stock. All of the outstanding shares of Voyager Common 
Stock and Voyager Preferred Stock have been duly authorized and validly 
issued, are fully paid and nonassessable and were issued in compliance with 
all applicable federal and state securities laws. There are, and have been, 
no preemptive rights with respect to the issuance of shares of Voyager Common 
Stock or Voyager Preferred Stock. Voyager has no shares reserved for issuance 
for any purpose. Except as set forth above, there are no shares of capital 
stock of Voyager authorized, issued or outstanding. There are no outstanding 
subscriptions, options, warrants, rights, convertible securities, or other 
agreements or

                                      -5-
<PAGE>

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-
<PAGE>

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-
<PAGE>

                  (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-
<PAGE>

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-
<PAGE>

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 
plans," as such term is defined in Section 3(3) of the Employee Retirement 
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 
or other entity, other than Howell, that is a party to, or in any property 
which is the subject of, business arrangements or relationships of any kind 
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 
or violations of Environmental Laws have occurred at or from any property 
which is the subject of this transaction or which was otherwise owned, 
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 
knowledge of Voyager, threatened, Environmental Claims against

                                      -10-
<PAGE>

Voyager; (iii) to the knowledge of Voyager, there are no underground storage 
tanks, polychlorinated biphenyls, or asbestos-containing materials owned by 
Voyager, or located at any facility owned or operated by Voyager; (iv) to the 
knowledge of Voyager, there are no facts, circumstances, or conditions that 
would reasonably be expected to give rise to liability under any 
Environmental Laws or to restrict, under any Environmental Laws or 
Environmental Permit in effect prior to or at the Closing Date, the 
ownership, occupancy, use or transferability of any property owned, operated, 
or leased by Voyager; (v) Voyager has not disposed, treated, or arranged for 
the disposal or treatment of any toxic or hazardous wastes, materials or 
Hazardous Materials at a site or location, or leased, used, operated or owned 
a site or location, which (x) has been or is proposed to be placed on the 
National Priorities List or its state equivalent pursuant to the 
Comprehensive Environmental Response, Compensation and Liability Act, as 
amended ("CERCLA"), or similar foreign, territorial or state law; (y) is 
subject to a lien, administrative order or other demand either to take 
response or other action under CERCLA or other Environmental Laws, or to 
develop or implement a "Corrective Action Plan" or "Compliance Plan," as each

       limiting the Borrower's obligation to confirm in writing any telephonic
       notice for a borrowing, continuation or conversion, the Agent may act
       without liability upon the basis of telephonic notice believed by the
       Agent in good faith to be from the Borrower prior to receipt of written
       confirmation.  In each such case, the Borrower hereby waives the right
       to dispute the Agent's record of the terms of such telephonic notice
       except in the case of gross negligence or willful misconduct by the
       Agent.

               (d)    CONTINUATION OPTIONS.  Subject to the provisions made in
       this Section 2.02(d), the Borrower may elect to continue all or any part
       of any Eurodollar Loan beyond the expiration of the then current
       Interest Period relating thereto by giving advance notice as provided in
       Section 2.02(c) to the Agent (which shall promptly notify the Lenders)
       of such election, specifying the amount of such Loan to be continued and

       proper election, the Borrower shall be deemed to have elected to convert

       All or any part of any Eurodollar Loan may be continued as provided
       herein, provided that (i) any continuation of any such Loan shall be (as

       time.

               (b)    The Borrower shall have the right to terminate or to
       reduce the amount of the Aggregate Facility A Maximum Credit Amounts at
       any time, or from time to time, upon not less than three (3) Business
       Days' prior notice to the Agent (which shall promptly notify the
       Lenders) of each such termination or reduction, which notice shall
       specify the effective date thereof and the amount of any such reduction
       (which shall not be less than $1,000,000 or any whole multiple of
       $1,000,000 in excess thereof) and shall be irrevocable and effective
       only upon receipt by the Agent.

               (c)    The Aggregate Facility A Maximum Credit Amounts once
       terminated or reduced may not be reinstated.

               Section 2.04  FEES.

               (a)    COMMITMENT FEE.  The Borrower shall pay to the Agent for
       the account of each Lender a commitment fee on the daily average unused
       amount of the Aggregate Facility A Commitments for the period from and
       including the Closing Date up to but excluding the earlier of the date
       the Aggregate Facility A Commitments are terminated or the Facility A
       Termination Date at a rate of 0.375% per annum so long as Facility B
       Loans are outstanding and after the Facility B Loans have been paid in
       full at a rate per annum set forth at the appropriate intersection in
       the table shown below based upon the Borrowing Base Utilization
       Percentage as in effect from time to time:

               (b)    LETTER OF CREDIT FEES.

                      (i)     The Borrower agrees to pay the Agent, for the
               account of the Lenders, commissions for issuing the Letters of
               Credit on the daily average outstanding of the maximum liability
               of the Issuing Bank existing from time to time under such Letter
               of Credit (calculated separately for each Letter of Credit) at
               the rate per annum equal to the Applicable Margin then in effect
               for Eurodollar Loans, provided that each Letter of Credit shall
               bear a minimum commission of $500.  Each Letter of Credit shall
               be deemed to be outstanding up to the full face amount of the
               Letter of Credit until the Issuing Bank has received the canceled
               Letter of Credit or a written cancellation of the Letter of
               Credit from the beneficiary of such Letter of Credit in form and
               substance acceptable to the Issuing Bank, or for any reductions
               in the amount of the Letter of Credit (other than from a
               drawing), written notification from the beneficiary of such
               Letter of Credit.  Such commissions are payable quarterly in
               arrears on each Quarterly Date and upon cancellation or
               expiration of each such Letter of Credit.

                      (ii)    The Borrower agrees to pay the Issuing Bank, for
               its own account, an issuing fee for issuing Letters of Credit on
               the daily average outstanding of the maximum liability of the
               Issuing Bank existing from time to time under such Letter of
               Credit (calculated separately for each Letter of Credit) at the
               rate of .10% per annum, payable quarterly in arrears on each
               Quarterly Date and upon cancellation or expiration of each such
               Letter of Credit. 

               (c)    On March 1, 1999, the Borrower agrees to pay to the
       Agent, for the account of the Lenders, a one-time fee of three percent
       (3%) on the then outstanding principal of Facility B Loans unless the
       Borrower has prepaid the principal balance outstanding on the Facility B
       Loans by $12,000,000 on or before that date.

               Section 2.05  SEVERAL OBLIGATIONS.  The failure of any Lender 
to make any Loan to be made by it or to provide funds for disbursements or 
reimbursements under Letters of Credit on the date specified therefor shall 
not relieve any other Lender of its obligation to make its Loan or provide 
funds on such date, but no Lender shall be responsible for the failure of any 
other Lender to make a Loan to be made by such other Lender or to provide 
funds to be provided by such other Lender.

               Section 2.06  NOTES.  The Facility A Loans made by each Lender 
shall be evidenced by a single promissory note of the Borrower in 
substantially the form of EXHIBIT A-1, dated (i) for the Existing Notes, the 
date stated thereon or (ii) the effective date of an Assignment pursuant to 
Section 12.06(b), payable to the order of such Lender in a principal amount 
equal to its Facility A Maximum Credit Amount as originally in effect and 
otherwise duly completed and such substitute Notes as required by Section 
12.06(b).  The Facility B Loans made by each Lender shall be evidenced by a 
single promissory note of the Borrower in substantially the form of EXHIBIT 
A-2, dated (i) for the Existing Notes, the Date stated thereon or (ii) the 
effective date of an Assignment pursuant to Section 12.06(b), payable to the 
order of such Lender and otherwise duly completed.

                                     -21-
<PAGE>

The date, amount, Type, interest rate and Interest Period of each Loan made 
by each Lender, and all payments made on account of the principal thereof, 
shall be recorded by such Lender on its books for its Notes, and, prior to 
any transfer may be endorsed by such Lender on the schedule attached to such 
Notes or any continuation thereof or on any separate record maintained by 
such Lender.  Failure to make any such notation or to attach a schedule shall 
not affect any Lender's or the Borrower's rights or obligations in respect of 
such Loans or affect the validity of such transfer by any Lender of its Note.

               Section 2.07  PREPAYMENTS.

               (a)    VOLUNTARY PREPAYMENTS.  The Borrower may prepay the Base
       Rate Loans upon not less than one (1) Business Day's prior notice to the
       Agent (which shall promptly notify the Lenders), which notice shall
       specify the prepayment date (which shall be a Business Day) and the
       amount of the prepayment (which shall be at least $500,000 or the
       remaining aggregate principal balance outstanding on the Notes) and
       shall be irrevocable and effective only upon receipt by the Agent,
       provided that interest on the principal prepaid, accrued to the
       prepayment date, shall be paid on the prepayment date.  The Borrower may
       prepay Eurodollar Loans on the same conditions as for Base Rate Loans
       (except that prior notice to the Agent shall be not less than three (3)
       Business Days for Eurodollar Loans) and in addition such prepayments of
       Eurodollar Loans shall be subject to the terms of Section 5.05 and shall
       be in an amount equal to all of the Eurodollar Loans for the Interest
       Period prepaid.

               (b)    MANDATORY PREPAYMENTS.

                      (i)     If, after giving effect to any termination or
       reduction of the Aggregate Facility A Maximum Credit Amounts pursuant to
       Section 2.03(b), the outstanding aggregate principal amount of the
       Facility A Loans plus the LC Exposure exceeds the Aggregate Facility A
       Maximum Credit Amounts, the Borrower shall (i) prepay the Facility A
       Loans on the date of such termination or reduction in an aggregate
       principal amount equal to the excess, together with interest on the
       principal amount paid accrued to the date of such prepayment and (ii) if
       any excess remains after prepaying all of the Facility A Loans because
       of LC Exposure, pay to the Agent on behalf of the Lenders an amount
       equal to the excess to be held as cash collateral as provided in Section
       2.10(b) hereof.

                      (ii)    Upon any redetermination of the amount of the
       Borrowing Base in accordance with Section 2.08, if the redetermined
       Borrowing Base is less than the aggregate outstanding principal amount
       of the Facility A Loans plus the LC Exposure, then the Borrower shall
       within thirty (30) days of receipt of written notice thereof: (i) prepay
       the Facility A Loans in an aggregate principal amount equal to such
       excess, together with interest on the principal amount paid accrued to
       the date of such prepayment and (ii) if a Borrowing Base deficiency
       remains after prepaying all of the Facility A Loans because of LC
       Exposure, the Borrower shall pay to the Agent on behalf of the Lenders
       an amount equal to such Borrowing Base deficiency to be held as cash
       collateral as provided in Section 2.10(b).

                                     -22-
<PAGE>

                      (iii)   From the net proceeds hereafter raised pursuant to
       Section 8.11 or Section 9.15(iv) and (v), the Loans shall be prepaid as
       follows:

                              (a)    the Facility A Notes shall be repaid and
               the  Borrowing Base reduced by the amount which the Majority
               Lenders determine in their sole discretion to be the value such
               sold assets should then carry for Borrowing Base purposes or, if
               applicable, by the Borrowing Base impact determined by the
               Majority Lenders in their sole discretion of subordinated
               interest carry;

                              (b)    the Facility B Notes shall be repaid with
               the remaining proceeds; and

                              (c)    if the Facility B Notes have been paid in
               full and a Default exists hereunder, the entire proceeds shall be
               applied to the Facility A Notes and the Borrowing Base reduced by
               the amount of such payment.

               (c)    GENERALLY.  Prepayments permitted or required under this
       Section 2.07 shall be without premium or penalty, except as required
       under Section 5.05 for prepayment of Eurodollar Loans.  Any prepayments
       on the Facility A Loans may be reborrowed subject to the then effective
       Aggregate Facility A Commitments. Any prepayments on the Facility B
       Loans may not be reborrowed and shall be applied to installments on the
       Facility B Notes in the inverse order of maturity.

               Section 2.08  BORROWING BASE.

               (a)    During the period from and after the Closing Date until
       the first redetermination pursuant to Section 2.08(d) or adjustment
       pursuant to Section 8.08(c), the amount of the Borrowing Base shall be
       as defined in Borrowing Base Letter.  The Borrowing Base shall be
       redetermined in accordance with Section 2.08(b) by the Agent with the
       concurrence of the Required Lenders and is subject to redetermination in
       accordance with Section 2.08(d).  Upon any redetermination of the
       Borrowing Base, such redetermination shall remain in effect until the
       next successive Redetermination Date.  "REDETERMINATION DATE" shall mean
       the date that the redetermined Borrowing Base becomes effective subject
       to the notice requirements specified in Section 2.08(e) both for
       scheduled redeterminations and unscheduled redeterminations.  So long as
       any of the Commitments are in effect or any LC Exposure or Facility A
       Loans are outstanding hereunder, this facility shall be governed by the
       then effective Borrowing Base. 

               (b)    Upon receipt of the reports required by Section 8.07 and
       such other reports, data and supplemental information as from time to
       time may be reasonably requested by the Agent, the Agent will
       redetermine the Borrowing Base.  Such redetermination will be in
       accordance with its normal and customary procedures for evaluating oil
       and gas reserves and other related assets as such exist at that
       particular time.  The Agent, in its sole discretion, may make
       adjustments to the rates, volumes and prices and other assumptions set
       forth therein in accordance with its normal and customary procedures for
       evaluating oil and gas 

                                     -23-
<PAGE>

       reserves and other related assets as such exist at that particular 
       time.  The oil and gas reserves and related assets shall include proved 
       developed producing reserves, proved developed non-producing reserves, 
       proved undeveloped reserves and related processing and gathering assets.
       The Agent shall propose to the Lenders a new Borrowing Base no less than 
       20 days before the Scheduled Redetermination Date.  After having 
       received notice of such proposal by the Agent, the Required Lenders 
       shall have 10 Business Days to agree or disagree with such proposal.  If 
       at the end of the 10 Business Days, any Lender has not communicated its 
       approval or disapproval, such silence shall be deemed to be an approval.
       If the Required Lenders have not approved within 10 Business Days, the 
       Required Lenders shall, within a reasonable period of time, agree on a 
       new Borrowing Base. 

               (c)    The Agent may exclude any Oil and Gas Property or portion
       of production therefrom or any income from any other Property from the
       Borrowing Base, at any time, because title information is not reasonably
       satisfactory, such Property is not assignable, or such Property is not
       Mortgaged Property (if required pursuant to Section 8.09).  Although the
       Agent may exclude any Property from the Borrowing Base to the extent
       title thereto is not reasonably satisfactory, it is understood that the
       Borrower is only required to furnish title information with respect to
       80% of the value of its Oil and Gas Properties covered by the subject
       Reserve Report(s). 

               (d)    So long as any of the Commitments are in effect and until
       payment in full of all Facility A Loans hereunder and termination of all
       outstanding Letters of Credit, on or around the first Business Day of
       each May 1 and November 1, commencing May 1, 1999 (each being a
       "SCHEDULED REDETERMINATION DATE"), the Lenders shall redetermine the
       amount of the Borrowing Base in accordance with Section 2.08(b).  In
       addition, beginning May 1, 1999 the Required Lenders and/or the Borrower
       may each initiate one additional redetermination of the Borrowing Base
       during any consecutive twelve (12) month period by specifying in writing
       the date on which such redetermination is to occur.  In addition, upon
       issuance of Subordinated Debt permitted pursuant to Section 9.01(g)
       hereof the Borrowing Base shall be redetermined to give weight to the
       interest carry on such Subordinated Debt as provided in the Borrowing
       Base Letter.

               (e)    The Agent shall promptly notify in writing the Borrower
       and the Lenders of the new Borrowing Base.  Any redetermination of the
       Borrowing Base shall not be in effect until written notice is received
       by the Borrower.

               Section 2.09  ASSUMPTION OF RISKS.  The Borrower assumes all 
risks of the acts or omissions of any beneficiary of any Letter of Credit or 
any transferee thereof with respect to its use of such Letter of Credit.  
Neither the Issuing Bank (except in the case of gross negligence or willful 
misconduct on the part of the Issuing Bank or any of its employees), its 
correspondents nor any Lender shall be responsible for the validity, 
sufficiency or genuineness of certificates or other documents or any 
endorsements thereon, even if such certificates or other documents should in 
fact prove to be invalid, insufficient, fraudulent or forged; for errors, 
omissions, interruptions or delays in transmissions or delivery of any 
messages by mail, telex, or otherwise, whether or not they be in code; for 
errors in translation or for errors in interpretation of technical terms; the 
validity or 

                                      -24-
<PAGE>

sufficiency of any instrument transferring or assigning or purporting to 
transfer or assign any Letter of Credit or the rights or benefits thereunder 
or proceeds thereof, in whole or in part, which may prove to be invalid or 
ineffective for any reason; the failure of any beneficiary or any transferee 
of any Letter of Credit to comply fully with conditions required in order to 
draw upon any Letter of Credit; or for any other consequences arising from 
causes beyond the Issuing Bank's control or the control of the Issuing Bank's 
correspondents.  In addition, neither the Issuing Bank, the Agent nor any 
Lender shall be responsible for any error, neglect, or default of any of the 
Issuing Bank's correspondents; and none of the above shall affect, impair or 
prevent the vesting of any of the Issuing Bank's, the Agent's or any Lender's 
rights or powers hereunder or under the Letter of Credit Agreements, all of 
which rights shall be cumulative.  The Issuing Bank and its correspondents 
may accept certificates or other documents that appear on their face to be in 
order, without responsibility for further investigation of any matter 
contained therein regardless of any notice or information to the contrary.  
In furtherance and not in limitation of the foregoing provisions, the 
Borrower agrees that any action, inaction or omission taken or not taken by 
the Issuing Bank or by any correspondent for the Issuing Bank in good faith 
in connection with any Letter of Credit, or any related drafts, certificates, 
documents or instruments, shall be binding on the Borrower and shall not put 
the Issuing Bank or its correspondents under any resulting liability to the 
Borrower.

               Section 2.10  OBLIGATION TO REIMBURSE AND TO PREPAY.

               (a)    If a disbursement by the Issuing Bank is made under any
       Letter of Credit, the Borrower shall pay to the Agent within two (2)
       Business Days after notice of any such disbursement is received by the
       Borrower, the amount of each such disbursement made by the Issuing Bank
       under the Letter of Credit (if such payment is not sooner effected as
       may be required under this Section 2.10 or under other provisions of the
       Letter of Credit), together with interest on the amount disbursed from
       and including the date of disbursement until payment in full of such
       disbursed amount at a varying rate per annum equal to (i) the then
       applicable interest rate for Base Rate Loans through the second Business
       Day after notice of such disbursement is received by the Borrower and
       (ii) thereafter, the Post-Default Rate for Base Rate Loans (but in no
       event to exceed the Highest Lawful Rate) for the period from and
       including the third Business Day following the date of such disbursement
       to and including the date of repayment in full of such disbursed amount. 
       The obligations of the Borrower under this Agreement with respect to
       each Letter of Credit shall be absolute, unconditional and irrevocable
       and shall be paid or performed strictly in accordance with the terms of
       this Agreement under all circumstances whatsoever, including, without
       limitation, but only to the fullest extent permitted by applicable law,
       the following circumstances: (i) any lack of validity or enforceability
       of this Agreement, any Letter of Credit or any of the Loan Documents;
       (ii) any amendment or waiver of (including any default), or any consent
       to departure from this Agreement (except to the extent permitted by any
       amendment or waiver), any Letter of Credit or any of the Loan Documents;
       (iii) the existence of any claim, set-off, defense or other rights which
       the Borrower may have at any time against the beneficiary of any Letter
       of Credit or any transferee of any Letter of Credit (or any Persons for
       whom any such beneficiary or any such transferee may be acting), the
       Issuing Bank, the Agent, any Lender or any other Person, whether in
       connection with this Agreement, any Letter of Credit, the Loan
       Documents, the transactions contemplated hereby or any unrelated

                                     -25-
<PAGE>

       transaction; (iv) any statement, certificate, draft, notice or any other
       document presented under any Letter of Credit proves to have been
       forged, fraudulent, insufficient or invalid in any respect or any
       statement therein proves to have been untrue or inaccurate in any
       respect whatsoever; (v) payment by the Issuing Bank under any Letter of
       Credit against presentation of a draft or certificate which appears on
       its face to comply, but does not comply, with the terms of such Letter
       of Credit; and (vi) any other circumstance or happening whatsoever,
       whether or not similar to any of the foregoing.

       Notwithstanding anything in this Agreement to the contrary, the Borrower
       will not be liable for payment or performance that results from the
       gross negligence or willful misconduct of the Issuing Bank, except (i)
       where the Borrower or any Subsidiary actually recovers the proceeds for
       itself or the Issuing Bank of any payment made by the Issuing Bank in
       connection with such gross negligence or willful misconduct or (ii) in
       cases where the Agent makes payment to the named beneficiary of a Letter
       of Credit in accordance with the terms thereof.

               (b)    In the event the principal amount then outstanding on and
       the accrued interest on the Loans has been accelerated pursuant to
       Section 10.02 or in the event of a payment or prepayment pursuant to
       Section 2.07(b), an amount equal to the LC Exposure (or the excess in
       the case of Section 2.07(b)), shall be deemed to be forthwith due and
       owing by the Borrower to the Issuing Bank, the Agent and the Lenders as
       of the date of any such occurrence; and the Borrower's obligation to pay
       such amount shall be absolute and unconditional, without regard to
       whether any beneficiary of any such Letter of Credit has attempted to
       draw down all or a portion of such amount under the terms of a Letter of
       Credit, and, to the fullest extent permitted by applicable law, shall
       not be subject to any defense or be affected by a right of set-off,
       counterclaim or recoupment which the Borrower may now or hereafter have
       against any such beneficiary, the Issuing Bank, the Agent, the Lenders
       or any other Person for any reason whatsoever.  Such payments shall be
       held by the Issuing Bank on behalf of the Lenders as cash collateral
       securing the LC Exposure in an account or accounts at the Principal
       Office; and the Borrower hereby grants to and by its deposit with the
       Agent grants to the Agent a security interest in such cash collateral. 
       In the event of any such payment by the Borrower of amounts contingently
       owing under outstanding Letters of Credit and in the event that
       thereafter drafts or other demands for payment complying with the terms
       of such Letters of Credit are not made prior to the respective
       expiration dates thereof, the Agent agrees, if no Event of Default has
       occurred and is continuing or if no other amounts are outstanding under
       this Agreement, the Notes or the Loan Documents, to remit to the
       Borrower amounts for which the contingent obligations evidenced by the
       Letters of Credit have ceased.

               (c)    Each Lender severally and unconditionally agrees that it
       shall promptly reimburse the Issuing Bank an amount equal to such
       Lender's Percentage Share of any disbursement made by the Issuing Bank
       under any Letter of Credit that is not reimbursed according to this
       Section 2.10.

               (d)    Notwithstanding anything to the contrary contained 
herein, if no Event of Default has occurred and is continuing and subject to 
availability under Section 2.01(a), to the extent the Borrower has not 
reimbursed the Issuing Bank for any drawn upon Letter of Credit within one 
(1) Business Days after notice of such disbursement has been received by the 
Borrower, the amount of such Letter of Credit reimbursement obligation shall 
automatically be funded by the Lenders as a Facility A Loan hereunder and 
used by the Lenders to pay such Letter of Credit reimbursement obligation.  
If an Event of Default has occurred and is continuing, or if the funding of 
such Letter of Credit reimbursement obligation as a Facility A Loan would 
cause the aggregate amount of all Facility A Loans outstanding to exceed the 
Aggregate Facility A Commitments (after reduction for LC Exposure), such 
Letter of Credit reimbursement obligation shall not be funded as a Facility A 
Loan, but instead shall accrue interest as provided in Section 2.10(a).

       Section 2.11  LENDING OFFICES.  The Loans of each Type made by each 
Lender shall be made and maintained at such Lender's Applicable Lending 
Office for Loans of such Type.

               Section 3.01  REPAYMENT OF LOANS.  

       (a)     FACILITY A LOANS.  In addition to any Mandatory Prepayments 
required by Section 2.07, on the Facility A Termination Date the Borrower 
shall repay the outstanding aggregate principal and accrued and unpaid 
interest under the Facility A Notes.
  
       (b)     FACILITY B LOANS.  On the Facility B Maturity Date the 
Borrower shall repay the outstanding aggregate principal and accrued and 
unpaid interest under the Facility B Notes.

       (c)     GENERALLY.  The Borrower will pay to the Agent, for the 
account of each Lender, the principal payments required by this Section 3.01.

               Section 3.02  INTEREST.

               (a)    INTEREST RATES.  The Borrower will pay to the Agent, for
       the account of each Lender, interest on the unpaid principal amount of
       each Loan made by such Lender for the period commencing on the date such
       Loan is made to, but excluding, the date such Loan shall be paid in
       full, at the following rates per annum:

                      (i)     if such a Loan is a Base Rate Loan, the
       Base Rate (as in effect from time to time) plus the Applicable
       Margin, but in no event to exceed the Highest Lawful Rate; and

                                     -27-
<PAGE>

                      (ii)    if such a Loan is a Eurodollar Loan, for
       each Interest Period relating thereto, the Eurodollar Rate for
       such Loan plus the Applicable Margin (as in effect from time to
       time), but in no event to exceed the Highest Lawful Rate.

               (b)    POST-DEFAULT RATE.  Notwithstanding the foregoing, the
       Borrower will pay to the Agent, for the account of each Lender interest
       at the applicable Post-Default Rate on any principal of any Loan made by
       such Lender, and (to the fullest extent permitted by law) on any other
       amount payable by the Borrower hereunder, under any Loan Document or
       under any Note held by such Lender to or for account of such Lender, for
       the period commencing on the date of an Event of Default until the same
       is paid in full or all Events of Default are cured or waived.

               (c)  DUE DATES.  Accrued interest on Base Rate Loans shall be
       payable on each Quarterly Date and accrued interest on each Eurodollar
       Loan shall be payable on the last day of the Interest Period therefor
       and, if such Interest Period is longer than three months at three-month
       intervals following the first day of such Interest Period, except that
       interest payable at the Post-Default Rate shall be payable from time to
       time on demand and interest on any Eurodollar Loan that is converted
       into a Base Rate Loan (pursuant to Section 5.04) shall be payable on the
       date of conversion (but only to the extent so converted).

               (d)  DETERMINATION OF RATES.  Promptly after the determination of
       any interest rate provided for herein or any change therein, the Agent
       shall notify the Lenders to which such interest is payable and the
       Borrower thereof.  Each determination by the Agent of an interest rate
       or fee hereunder shall, except in cases of manifest error, be final,
       conclusive and binding on the parties.

               Section 4.01  PAYMENTS.  Except to the extent otherwise 
provided herein, all payments of principal, interest and other amounts to be 
made by the Borrower under this Agreement, the Notes and the Letter of Credit 
Agreements shall be made in Dollars, in immediately available funds, to the 
Agent at such account as the Agent shall specify by notice to the Borrower 
from time to time, not later than 11:00 a.m. Houston, Texas time on the date 
on which such payments shall become due (each such payment made after such 
time on such due date to be deemed to have been made on the next succeeding 
Business Day).  Such payments shall be made without (to the fullest extent 
permitted by applicable law) defense, set-off or counterclaim.  Each payment 
received by the Agent under this Agreement or any Note for account of a 
Lender shall be paid promptly to such Lender in immediately available funds.  
Except as otherwise provided in the definition of "Interest Period", if the 
due date of any payment under this Agreement or any Note would otherwise fall 
on a day which is not a Business Day such date shall be extended to the next 
succeeding Business Day and interest shall be payable for any principal so 
extended for the period of such extension. At the time of each payment to the 
Agent of any principal of or interest on any borrowing, the Borrower shall 
notify the Agent of the Loans to which such payment shall apply.  In the 
absence of such notice the Agent may specify the Loans to which such payment 
shall apply, but to the extent possible such payment or prepayment will be 
applied first to the Loans comprised of Base Rate Loans. 

               Section 4.02  PRO RATA TREATMENT.  Except to the extent 
otherwise provided herein each Lender agrees that:  (i) each borrowing from 
the Lenders under Section 2.01 and each continuation and conversion under 
Section 2.02 shall be made from the Lenders pro rata in accordance with their 
Percentage Share, each payment of commitment fee or other fees under Section 
2.04(a) and Section 2.04(b) shall be made for the account of the Lenders pro 
rata in accordance with their Percentage Share, and each termination or 
reduction of the amount of the Aggregate Facility A Maximum Credit Amounts 
under Section 2.03(b) shall be applied to the Commitment of each Lender, pro 
rata according to the amounts of its respective Commitment; (ii) each payment 
of principal of Loans by the Borrower shall be made for the account of the 
Lenders pro rata in accordance with the respective unpaid principal amount of 
the Loans held by the Lenders; and (iii) each payment of interest on Loans by 
the Borrower shall be made for the account of the Lenders pro rata in 
accordance with the amounts of interest due and payable to the respective 
Lenders; and (iv) each reimbursement by the Borrower of disbursements under 
Letters of Credit shall be made for the account of the Issuing Bank or, if 
funded by the Lenders, pro rata for the account of the Lenders, in accordance 
with the amounts of reimbursement obligations due and payable to each 
respective Lender.

               Section 4.03  COMPUTATIONS.  Interest on Eurodollar Loans and 
fees shall be computed on the basis of a year of 360 days and actual days 
elapsed (including the first day but excluding the last day) occurring in the 
period for which such interest is payable, unless such calculation would 
exceed the Highest Lawful Rate, in which case interest shall be calculated on 
the per annum basis of a year of 365 or 366 days, as the case may be.  
Interest on Base Rate Loans shall be computed on the basis of a year of 365 
or 366 days, as the case may be, and actual days elapsed (including the first 
day but excluding the last day) occurring in the period for which such 
interest is payable.

<PAGE>

               Section 4.04  NON-RECEIPT OF FUNDS BY THE AGENT.  Unless the 
Agent shall have been notified by a Lender or the Borrower prior to the date 
on which such notifying party is scheduled to make payment to the Agent (in 
the case of a Lender) of the proceeds of a Loan or a payment under a Letter 
of Credit to be made by it hereunder or (in the case of the Borrower) a 
payment to the Agent for the account of one or more of the Lenders hereunder 
(such payment being herein called the "REQUIRED PAYMENT"), which notice shall 
be effective upon receipt, that it does not intend to make the Required 
Payment to the Agent, the Agent may assume that the Required Payment has been 
made and may, in reliance upon such assumption (but shall not be required 
to), make the amount thereof available to the intended recipient(s) on such 
date and, if such Lender or the Borrower (as the case may be) has not in fact 
made the Required Payment to the Agent, the recipient(s) of such payment 
shall, on demand, repay to the Agent the amount so made available together 
with interest thereon in respect of each day during the period commencing on 
the date such amount was so made available by the Agent until, but excluding, 
the date the Agent recovers such amount at a rate per annum which, for any 
Lender as recipient, will be equal to the Federal Funds Rate, and for the 
Borrower as recipient, will be equal to the Base Rate plus the Applicable 
Margin.  

               Section 4.05  SET-OFF, SHARING OF PAYMENTS, ETC.

               (a)    The Borrower agrees that, in addition to (and without
       limitation of) any right of set-off, bankers' lien or counterclaim a
       Lender may otherwise have, each Lender shall have the right and be
       entitled (after consultation with the Agent), at its option, to offset
       balances held by it or by any of its Affiliates for the account of the
       Borrower at any of its offices, in Dollars or in any other currency,
       against any principal of or interest on any of such Lender's Loans, or
       any other amount payable to such Lender hereunder, which is not paid
       when due (regardless of whether such balances are then due to the
       Borrower), in which case it shall promptly notify the Borrower and the
       Agent thereof, provided that such Lender's failure to give such notice
       shall not affect the validity thereof.

               (b)    If any Lender shall obtain payment of any principal of or
       interest on any Loan made by it to the Borrower under this Agreement (or
       reimbursement as to any Letter of Credit) through the exercise of any
       right of set-off, banker's lien or counterclaim or similar right or
       otherwise, and, as a result of such payment, such Lender shall have
       received a greater percentage of the principal or interest (or
       reimbursement) then due hereunder by the Borrower to such Lender than
       the percentage received by any other Lenders, it shall promptly (i)
       notify the Agent and each other Lender thereof and (ii) purchase from
       such other Lenders participations in (or, if and to the extent specified
       by such Lender, direct interests in) the Loans (or participations in
       Letters of Credit) made by such other Lenders (or in interest due
       thereon, as the case may be) in such amounts, and make such other
       adjustments from time to time as shall be equitable, to the end that all
       the Lenders shall share the benefit of such excess payment (net of any
       expenses which may be incurred by such Lender in obtaining or preserving
       such excess payment) pro rata in accordance with the unpaid principal
       and/or interest on the Loans held by each of the Lenders (or
       reimbursements of Letters of Credit).  To such end all the Lenders shall
       make appropriate adjustments among themselves (by the resale of
       participations sold or otherwise) if such payment is rescinded or must
       otherwise be restored.  The Borrower agrees that any Lender so
       purchasing a 

                                      -30-
<PAGE>

       participation (or direct interest) in the Loans made by other Lenders 
       (or in interest due thereon, as the case may be) may exercise all rights 
       of set-off, banker's lien, counterclaim or similar rights with respect 
       to such participation as fully as if such Lender were a direct holder 
       of Loans (or Letters of Credit) in the amount of such participation.  
       Nothing contained herein shall require any Lender to exercise any such 
       right or shall affect the right of any Lender to exercise, and retain 
       the benefits of exercising, any such right with respect to any other 
       indebtedness or obligation of the Borrower.  If under any applicable 
       bankruptcy, insolvency or other similar law, any Lender receives a 
       secured claim in lieu of a set-off to which this Section 4.05 applies, 
       such Lender shall, to the extent practicable, exercise its rights in 
       respect of such secured claim in a manner consistent with the rights 
       of the Lenders entitled under this Section 4.05 to share the benefits 
       of any recovery on such secured claim.

               Section 4.06  TAXES.

               (a)    PAYMENTS FREE AND CLEAR.  Any and all payments by the
       Borrower hereunder shall be made, in accordance with Section 4.01, free
       and clear of and without deduction for any and all present or future
       taxes, levies, imposts, deductions, charges or withholdings, and all
       liabilities with respect thereto, EXCLUDING, in the case of each Lender,
       the Issuing Bank and the Agent, taxes imposed on its income, and
       franchise or similar taxes imposed on it, by (i) any jurisdiction (or
       political subdivision thereof) of which the Agent, the Issuing Bank or
       such Lender, as the case may be, is a citizen or resident or in which
       such Lender has an Applicable Lending Office, (ii) the jurisdiction (or
       any political subdivision thereof) in which the Agent, the Issuing Bank
       or such Lender is organized, or (iii) any jurisdiction (or political
       subdivision thereof) in which such Lender, the Issuing Bank or the Agent
       is presently doing business which taxes are imposed solely as a result
       of doing business in such jurisdiction (all such non-excluded taxes,
       levies, imposts, deductions, charges, withholdings and liabilities being
       hereinafter referred to as "TAXES").  If the Borrower shall be required
       by law to deduct any Taxes from or in respect of any sum payable
       hereunder to the Lenders, the Issuing Bank or the Agent (i) the sum
       payable shall be increased by the amount necessary so that after making
       all required deductions (including deductions applicable to additional
       sums payable under this Section 4.06) such Lender, the Issuing Bank or
       the Agent (as the case may be) shall receive an amount equal to the sum
       it would have received had no such deductions been made, (ii) the
       Borrower shall make such deductions and (iii) the Borrower shall pay the
       full amount deducted to the relevant taxing authority or other
       Governmental Authority in accordance with applicable law.  

               (b)    OTHER TAXES.  In addition, to the fullest extent
       permitted by applicable law, the Borrower agrees to pay any present or
       future stamp or documentary taxes or any other excise or property taxes,
       charges or similar levies that arise from any payment made hereunder or
       from the execution, delivery or registration of, or otherwise with
       respect to, this Agreement or any Loan Documents (hereinafter referred
       to as "OTHER TAXES").  

               (c)    INDEMNIFICATION.  TO THE FULLEST EXTENT PERMITTED BY
       APPLICABLE LAW, THE BORROWER WILL INDEMNIFY EACH LENDER AND THE ISSUING
       BANK AND THE  AGENT FOR THE FULL AMOUNT OF TAXES AND OTHER TAXES
       (INCLUDING, BUT NOT 

                                      -31-
<PAGE>

       LIMITED TO, ANY TAXES OR OTHER TAXES IMPOSED BY ANY GOVERNMENTAL 
       AUTHORITY ON AMOUNTS PAYABLE UNDER THIS SECTION 4.06) PAID BY SUCH 
       LENDER, THE ISSUING BANK OR THE AGENT (ON THEIR BEHALF OR ON BEHALF 
       OF ANY LENDER), AS THE CASE MAY BE, AND ANY LIABILITY (INCLUDING
       PENALTIES, INTEREST AND EXPENSES) ARISING THEREFROM OR WITH RESPECT
       THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY OR
       LEGALLY ASSERTED UNLESS THE PAYMENT OF SUCH TAXES WAS NOT CORRECTLY OR
       LEGALLY ASSERTED AND SUCH LENDER'S PAYMENT OF SUCH TAXES OR OTHER TAXES
       WAS THE RESULT OF ITS GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.  ANY
       PAYMENT PURSUANT TO SUCH INDEMNIFICATION SHALL BE MADE WITHIN THIRTY
       (30) DAYS AFTER THE DATE ANY LENDER, THE ISSUING BANK OR THE AGENT, AS
       THE CASE MAY BE, MAKES WRITTEN DEMAND THEREFOR.  IF ANY LENDER OR THE
       AGENT RECEIVES A REFUND OR CREDIT IN RESPECT OF ANY TAXES OR OTHER TAXES
       FOR WHICH SUCH LENDER, ISSUING BANK OR THE AGENT HAS RECEIVED PAYMENT
       FROM THE BORROWER IT SHALL PROMPTLY NOTIFY THE BORROWER OF SUCH REFUND
       OR CREDIT AND SHALL, IF NO DEFAULT HAS OCCURRED AND IS CONTINUING,
       WITHIN THIRTY (30) DAYS AFTER RECEIPT OF A REQUEST BY THE BORROWER (OR
       PROMPTLY UPON RECEIPT, IF THE BORROWER HAS REQUESTED APPLICATION FOR
       SUCH REFUND OR CREDIT PURSUANT HERETO), PAY AN AMOUNT EQUAL TO SUCH
       REFUND OR CREDIT TO THE BORROWER WITHOUT INTEREST (BUT WITH ANY INTEREST
       SO REFUNDED OR CREDITED), PROVIDED THAT THE BORROWER, UPON THE REQUEST
       OF SUCH LENDER, THE ISSUING BANK OR THE AGENT, AGREES TO RETURN SUCH
       REFUND OR CREDIT (PLUS PENALTIES, INTEREST OR OTHER CHARGES) TO SUCH
       LENDER OR THE AGENT IN THE EVENT SUCH LENDER OR THE AGENT IS REQUIRED TO
       REPAY SUCH REFUND OR CREDIT.

               (d)    LENDER REPRESENTATIONS.

<PAGE>

                      (i)     Each Lender represents that it is either (1) a
               banking association or corporation organized under the laws of
               the United States of America or any state thereof or (2) it is
               entitled to complete exemption from United States withholding tax
               imposed on or with respect to any payments, including fees, to be
               made to it pursuant to this Agreement (A) under an applicable
               provision of a tax convention to which the United States of
               America is a party or (B) because it is acting through a branch,
               agency or office in the United States of America and any payment
               to be received by it hereunder is effectively connected with a
               trade or business in the United States of America.  Each Lender
               that is not a banking association or corporation organized under
               the laws of the United States of America or any state thereof
               agrees to provide to the Borrower and the Agent on the Closing
               Date, or on the date of its delivery of the Assignment pursuant
               to which it becomes a Lender, and at such other times as required
               by United States law or as the Borrower or the Agent shall
               reasonably request, two accurate and complete original signed
               copies of either (A) Internal Revenue Service Form 4224 (or
               successor form) certifying that all payments to be made to it
               hereunder will be effectively connected to a United States trade
               or business (the "FORM 4224 CERTIFICATION") or (B) Internal
               Revenue Service Form 1001 (or successor form) certifying that it
               is entitled to the benefit of a provision of a tax convention to
               which the United States of America is a party which completely
               exempts from United States withholding tax all payments to be
               made to it hereunder (the "FORM 1001 CERTIFICATION").  In
               addition, each Lender agrees that if it previously filed a Form
               4224 Certification, it will deliver to the Borrower and the Agent
               a new Form 4224 Certification prior to the first payment date
               occurring in each of its subsequent taxable years; and if it
               previously filed a Form 1001 Certification, it will deliver to
               the Borrower and the Agent a new certification prior to the first
               payment date falling in the third year following the previous
               filing of such certification.  Each Lender also agrees to deliver
               to the Borrower and the Agent such other or supplemental forms as
               may at any time be required as a result of changes in applicable
               law or regulation in order to confirm or maintain in effect its
               entitlement to exemption from United States withholding tax on
               any payments hereunder, PROVIDED that the circumstances of such
               Lender at the relevant time and applicable laws permit it to do
               so.  If a Lender determines, as a result of any change in either
               (i) a Governmental Requirement or (ii) its circumstances, that it
               is unable to submit any form or certificate that it is obligated
               to submit pursuant to this Section 4.06, or that it is required
               to withdraw or cancel any such form or certificate previously
               submitted, it shall promptly notify the Borrower and the Agent of
               such fact.  If a Lender is organized under the laws of a
               jurisdiction outside the United States of America, unless the
               Borrower and the Agent have received a Form 1001 Certification or
               Form 4224 Certification satisfactory to them indicating that all
               payments to be made to such Lender hereunder are not subject to
               United States withholding tax, the Borrower shall withhold taxes
               from such payments at the applicable statutory rate.  Each Lender
               agrees to indemnify and hold harmless the Borrower or Agent, as
               applicable, from any United States taxes, penalties, interest and
               other expenses, costs and losses incurred or payable by (i) the
               Agent as a result of such Lender's failure to submit any form or
               certificate that it is required to provide pursuant to this
               Section 

                                      -33-
<PAGE>

               4.06 or (ii) the Borrower or the Agent as a result of their 
               reliance on any such form or certificate which such Lender has 
               provided to them pursuant to this Section 4.06.  

                      (ii)    For any period with respect to which a Lender has
               failed to provide the Borrower with the form required pursuant to
               this Section 4.06, if any, (other than if such failure is due to
               a change in a Governmental Requirement occurring subsequent to
               the date on which a form originally was required to be provided),
               such Lender shall not be entitled to indemnification under
               Section 4.06 with respect to taxes imposed by the United States
               which taxes would not have been imposed but for such failure to
               provide such forms; PROVIDED, HOWEVER, that if a Lender, which is
               otherwise exempt from or subject to a reduced rate of withholding
               tax, becomes subject to taxes because of its failure to deliver a
               form required hereunder, the Borrower shall take such steps as
               such Lender shall reasonably request to assist such Lender to
               recover such taxes.

                      (iii)   Any Lender claiming any additional amounts payable
               pursuant to this Section 4.06 shall use reasonable efforts
               (consistent with legal and regulatory restrictions) to file any
               certificate or document requested by the Borrower or the Agent or
               to change the jurisdiction of its Applicable Lending Office or to
               contest any tax imposed if the making of such a filing or change
               or contesting such tax would avoid the need for or reduce the
               amount of any such additional amounts that may thereafter accrue
               and would not, in the sole determination of such Lender, be
               otherwise disadvantageous to such Lender.

                                CAPITAL ADEQUACY

               Section 5.01  ADDITIONAL COSTS.  

               (a)    EURODOLLAR REGULATIONS, ETC.  The Borrower shall pay
       directly to each Lender from time to time such amounts as such Lender
       may determine to be necessary to compensate such Lender for any costs
       which it determines are attributable to its making or maintaining of any
       Eurodollar Loans or issuing or participating in Letters of Credit
       hereunder or its obligation to make any Eurodollar Loans or issue or
       participate in any Letters of Credit hereunder, or any reduction in any
       amount receivable by such Lender hereunder in respect of any of such
       Eurodollar Loans, Letters of Credit or such obligation (such increases
       in costs and reductions in amounts receivable being herein called
       "ADDITIONAL COSTS"), resulting from any Regulatory Change which:
       (i) changes the basis of taxation of any amounts payable to such Lender
       under this Agreement or any Note in respect of any of such Eurodollar
       Loans or Letters of Credit (other than taxes imposed on the overall net
       income of such Lender or of its Applicable Lending Office for any of
       such Eurodollar Loans by the jurisdiction in which such Lender has its
       principal office or Applicable Lending Office); or (ii) imposes or
       modifies any reserve, special deposit, minimum capital, capital 

                                      -34-
<PAGE>

       ratio or similar requirements relating to any extensions of credit or 
       other assets of, or any deposits with or other liabilities of such 
       Lender, or the Commitment or Loans of such Lender or the Eurodollar 
       interbank market; or (iii) imposes any other condition affecting this 
       Agreement or any Note (or any of such extensions of credit or 
       liabilities) or such Lender's Commitment or Loans.  Each Lender will 
       notify the Agent and the Borrower of any event occurring after the 
       Closing Date which will entitle such Lender to compensation pursuant to 
       this Section 5.01(a) as promptly as practicable after it obtains 
       knowledge thereof and determines to request such compensation, and will 
       designate a different Applicable Lending Office for the Loans of such 
       Lender affected by such event if such designation will avoid the need 
       for, or reduce the amount of, such compensation and will not, in the 
       sole opinion of such Lender, be disadvantageous to such Lender, 
       provided that such Lender shall have no obligation to so designate an 
       Applicable Lending Office located in the United States.  If any Lender 
       requests compensation from the Borrower under this Section 5.01(a), the 
       Borrower may, by notice to such Lender, suspend the obligation of such 
       Lender to make additional Loans of the Type with respect to which such 
       compensation is requested until the Regulatory Change giving rise to 
       such request ceases to be in effect (in which case the provisions of 
       Section 5.04 shall be applicable).

               (b)    REGULATORY CHANGE. Without limiting the effect of the
       provisions of Section 5.01(a), in the event that at any time (by reason
       of any Regulatory Change arising after the Closing Date affecting
       (A) any Lender, (B) the Eurodollar interbank market or (C) such Lender's
       position in such market), the Eurodollar Rate, as determined in good
       faith by such Lender, will not adequately and fairly reflect the cost to
       such Lender of funding its Eurodollar Loans, then, if such Lender so
       elects, by notice to the Borrower and the Agent, the obligation of such
       Lender to make additional Eurodollar Loans shall be suspended until such
       Regulatory Change ceases to be in effect (in which case the provisions
       of Section 5.04 shall be applicable).

               (c)    CAPITAL ADEQUACY.  Without limiting the effect of the
       foregoing provisions of this Section 5.01 (but without duplication), the
       Borrower shall pay directly to any Lender from time to time on request
       such amounts as such Lender may reasonably determine to be necessary to
       compensate such Lender or its parent or holding company for any costs
       which it determines are attributable to the maintenance by such Lender
       or its parent or holding company (or any Applicable Lending Office),
       pursuant to any Regulatory Change, of capital in respect of its
       Commitment, its Note, or its Loans or any interest held by it in any
       Letter of Credit, such compensation to include, without limitation, an
       amount equal to any reduction of the rate of return on assets or equity
       of such Lender or its parent or holding company (or any Applicable
       Lending Office) to a level below that which such Lender or its parent or
       holding company (or any Applicable Lending Office) could have achieved
       but for such Regulatory Change.  Such Lender will notify the Borrower
       that it is entitled to compensation pursuant to this Section 5.01(c) as
       promptly as practicable after it determines to request such
       compensation.

               (d)    COMPENSATION PROCEDURE.  Any Lender notifying the
       Borrower of the incurrence of additional costs under this Section 5.01
       shall in such notice to the Borrower 

                                      -35-
<PAGE>

       and the Agent set forth in reasonable detail the basis and amount of 
       its request for compensation.  Determinations and allocations by each 
       Lender for purposes of this Section 5.01 of the effect of any Regulatory 
       Change pursuant to Section 5.01(a) or (b), or of the effect of capital 
       maintained pursuant to Section 5.01(c), on its costs or rate of return 
       of maintaining Loans or its obligation to make Loans or issue Letters of 
       Credit, or on amounts receivable by it in respect of Loans or Letters of 
       Credit, and of the amounts required to compensate such Lender under this 
       Section 5.01, shall be conclusive and binding for all purposes, provided 
       that such determinations and allocations are made on a reasonable basis 
       and provided such compensation procedure is on a basis similar to the 
       basis upon which such Lender is charging other similarly situated 
       borrowers.  Any request for additional compensation under this Section 
       5.01 shall be paid by the Borrower within thirty (30) days of the receipt
       by the Borrower of the notice described in this Section 5.01(d).  No 
       Lender shall be entitled to recover costs under this Section 5.01 
       incurred or accrued more than 180 days prior to the notice described in 
       this Section 5.01(d).

               Section 5.02  LIMITATION ON EURODOLLAR LOANS.  Anything herein 
to the contrary notwithstanding, if, on or prior to the determination of any 
Eurodollar Rate for any Interest Period:

               (i)    the Agent determines (which determination shall be
       conclusive, absent manifest error) that quotations of interest
       rates for the relevant deposits referred to in the definition of
       "Eurodollar Rate" in Section 1.02 are not being provided in the
       relevant amounts or for the relevant maturities for purposes of
       determining rates of interest for Eurodollar Loans as provided
       herein; or

               (ii)   the Majority Lenders determine (which
       determination shall be conclusive, absent manifest error) that
       the relevant rates of interest referred to in the definition of
       "Eurodollar Rate" in Section 1.02 upon the basis of which the
       rate of interest for Eurodollar Loans for such Interest Period is
       to be determined are not sufficient to adequately cover the cost
       to the Lenders of making or maintaining Eurodollar Loans;

then the Agent shall give the Borrower prompt notice thereof, and so long as
such condition remains in effect, the Lenders shall be under no obligation to
make additional Eurodollar Loans.

               Section 5.03  ILLEGALITY.  Notwithstanding any other provision 
of this Agreement, in the event that it becomes unlawful for any Lender or 
its Applicable Lending Office to honor its obligation to make or maintain 
Eurodollar Loans hereunder, then such Lender shall promptly notify the 
Borrower thereof and such Lender's obligation to make Eurodollar Loans shall 
be suspended until such time as such Lender may again make and maintain 
Eurodollar Loans (in which case the provisions of Section 5.04 shall be 
applicable).

               Section 5.04  BASE RATE LOANS PURSUANT TO SECTIONS 5.01, 5.02 
AND 5.03.  If the obligation of any Lender to make Eurodollar Loans shall be 
suspended pursuant to Sections 5.01, 5.02 or 5.03 ("AFFECTED LOANS"), all 
Affected Loans which would otherwise be made by such Lender shall be made 
instead as Base Rate Loans (and, if an event referred to in Section 5.01(b) 
or 

                                      -36-
<PAGE>

Section 5.03 has occurred and such Lender so requests by notice to the 
Borrower, all Affected Loans of such Lender then outstanding shall be 
automatically converted into Base Rate Loans on the date specified by such 
Lender in such notice) and, to the extent that Affected Loans are so made as 
(or converted into) Base Rate Loans, all payments of principal which would 
otherwise be applied to such Lender's Affected Loans shall be applied instead 
to its Base Rate Loans.

               Section 5.05  COMPENSATION.  The Borrower shall pay to each 
Lender within thirty (30) days of receipt of written request of such Lender 
(which request shall set forth, in reasonable detail, the basis for 
requesting such amounts and which shall be conclusive and binding for all 
purposes provided that such determinations are made on a reasonable basis), 
such amount or amounts as shall compensate it for any loss (excluding loss of 
anticipated profits), cost, expense or liability which such Lender determines 
are attributable to:

               (i)    any payment, prepayment or conversion of a
       Eurodollar Loan properly made by such Lender or the Borrower for
       any reason (including, without limitation, the acceleration of
       the Loans pursuant to Section 10.01) on a date other than the
       last day of the Interest Period for such Loan; or

               (ii)   any failure by the Borrower for any reason
       (including but not limited to, the failure of any of the
       conditions precedent specified in Article VI to be satisfied) to
       borrow, continue or convert a Eurodollar Loan from such Lender on
       the date for such borrowing, continuation or conversion specified
       in the relevant notice given pursuant to Section 2.02(c).

               Section 5.06  REPLACEMENT LENDERS.

               (a)    If any Lender has notified the Borrower and the Agent of
       its incurring additional costs under Section 5.01 or has required the
       Borrower to make payments for Taxes under Section 4.06, then the
       Borrower may, unless such Lender has notified the Borrower and the Agent
       that the circumstances giving rise to such notice no longer apply,
       terminate, in whole but not in part, the Commitment of any Lender (other
       than the Agent) (the "TERMINATED LENDER") at any time upon five (5)
       Business Days' prior written notice to the Terminated Lender and the
       Agent (such notice referred to herein as a "NOTICE OF TERMINATION").  

               (b)    In order to effect the termination of the Commitment of
       the Terminated Lender, the Borrower shall: (i) obtain an agreement with
       one or more Lenders to increase their Commitment or Commitments and/or
       (ii) request any one or more other banking institutions to become
       parties to this Agreement in place and instead of such Terminated Lender
       and agree to accept a Commitment or Commitments; PROVIDED, HOWEVER, that
       such one or more other banking institutions are reasonably acceptable to
       the Agent and become parties by executing an Assignment (the Lenders or
       other banking institutions that agree to accept in whole or in part the
       Commitment of the Terminated Lender being referred to herein as the
       "REPLACEMENT LENDERS"), such that the aggregate increased and/or
       accepted Commitments of the Replacement Lenders under clauses (i) and
       (ii) above equal the Commitment of the Terminated Lender.

                                      -37-
<PAGE>

               (c)    The Notice of Termination shall include the name of the
       Terminated Lender, the date the termination will occur (the "LENDER
       TERMINATION DATE"), and the Replacement Lender or Replacement Lenders to
       which the Terminated Lender will assign its Commitment and, if there
       will be more than one Replacement Lender, the portion of the Terminated
       Lender's Commitment to be assigned to each Replacement Lender.  

               (d)    On the Lender Termination Date, (i) the Terminated Lender
       shall by execution and delivery of an Assignment assign its Commitment
       to the Replacement Lender or Replacement Lenders (pro rata, if there is
       more than one Replacement Lender, in proportion to the portion of the
       Terminated Lender's Commitment to be assigned to each Replacement
       Lender) indicated in the Notice of Termination and shall assign to the
       Replacement Lender or Replacement Lenders each of its Loans (if any)
       then outstanding and participation interests in Letters of Credit (if
       any) then outstanding pro rata as aforesaid), (ii) the Terminated Lender
       shall endorse its Notes, payable without recourse, representation or
       warranty to the order of the Replacement Lender or Replacement Lenders
       (pro rata as aforesaid), (iii) the Replacement Lender or Replacement
       Lenders shall purchase the Notes held by the Terminated Lender (pro rata
       as aforesaid) at a price equal to the unpaid principal amount thereof
       plus interest and facility and other fees accrued and unpaid to the
       Lender Termination Date, and (iv) the Replacement Lender or Replacement
       Lenders will thereupon (pro rata as aforesaid) succeed to and be
       substituted in all respects for the Terminated Lender with like effect
       as if becoming a Lender pursuant to the terms of Section 12.06(b), and
       the Terminated Lender will have the rights and benefits of an assignor
       under Section 12.06(b).  To the extent not in conflict, the terms of
       Section 12.06(b) shall supplement the provisions of this Section
       5.06(d).  For each assignment made under this Section 5.06, the
       Replacement Lender shall pay to the Agent the processing fee provided
       for in Section 12.06(b).  The Borrower will be responsible for the
       payment of any breakage costs associated with termination and
       Replacement Lenders, as set forth in Section 5.05.

               Section 6.01  REARRANGEMENT.

               The obligation of the Lenders to make the Rearrangement is 
subject to the receipt by the Agent of the following documents and 
satisfaction of the other conditions provided in this Section 6.01, each of

       transactions contemplated in those documents, (ii) the officers of the
       Borrower (y) who are authorized to sign the Loan Documents to which

       articles or certificate of incorporation and bylaws of the Borrower have 
       not been amended or modified since December 17, 1997.  The Agent and the 
       Lenders may conclusively rely on such certificates until the Agent 
       receives notice in writing from the Borrower to the contrary. 

               (b)    A certificate of the Secretary or an Assistant Secretary
       of the Guarantor setting forth (i) resolutions of its board of directors

       officers, and (iv) a certification that the articles or certificate of
       incorporation and bylaws of the Guarantor have not been amended or

       writing from the Guarantor to the contrary. 

               (c)    Certificates of the appropriate state agencies with

       special counsel to the Agent may reasonably request.

<PAGE>

               Section 6.02  INITIAL AND SUBSEQUENT LOANS AND LETTERS OF 
CREDIT. The obligation of the Lenders to make Loans to the Borrower upon the 
occasion of each borrowing hereunder and to issue, renew, extend or reissue 
Letters of Credit for the account of the Borrower is subject to the further 
conditions precedent that, as of the date of such Loans and after giving 
effect thereto:

       (a) no Default shall have occurred and be continuing; 

       (b) no Material Adverse Effect shall have occurred and be continuing; 
and

       (c) the representations and warranties made by the Borrower in Article 
VII and in the Loan Documents shall be true in all material respects on and 
as of the date of the making of such Loans or issuance, renewal, extension or 
reissuance of a Letter of Credit with the same force and effect as if made on 
and as of such date and following such new borrowing, except to the extent 
such representations and warranties are expressly limited to an earlier date 
or the Majority Lenders may expressly consent in writing to the contrary.  

       Each request for a borrowing or issuance, renewal, extension or 
reissuance of a Letter of Credit by the Borrower hereunder shall constitute a 
certification by the Borrower to the effect set forth in Section 6.02(c) 
(both as of the date of such notice and, unless the Borrower otherwise 
notifies the Agent prior to the date of and immediately following such 
borrowing or issuance, renewal, extension or reissuance of a Letter of Credit 
as of the date thereof).

               Section 6.03  CONDITIONS PRECEDENT FOR THE BENEFIT OF LENDERS. 
All conditions precedent to the obligations of the Lenders to make any Loan 
are imposed hereby solely for the benefit of the Lenders, and no other Person 
may require satisfaction of any such condition precedent or be entitled to 
assume that the Lenders will refuse to make any Loan in the absence of strict 
compliance with such conditions precedent.

               Section 6.04  NO WAIVER.  No waiver of any condition precedent 
shall preclude the Agent or the Lenders from requiring such condition to be 
met prior to making any subsequent Loan or preclude the Lenders from 
thereafter declaring that the failure of the Borrower to satisfy such 
condition precedent constitutes a Default.

                                   ARTICLE VII

                          REPRESENTATIONS AND WARRANTIES

       The Borrower represents and warrants to the Agent and the Lenders that 
(each representation and warranty herein is given as of the Closing Date and 
shall be deemed repeated and reaffirmed on the dates of each borrowing and 
issuance, renewal, extension or reissuance of a Letter of Credit as provided 
in Section 6.02):

                                      -40-
<PAGE>

               Section 7.01  CORPORATE EXISTENCE.  Each of the Borrower and 
each Subsidiary:  (i) is a corporation duly organized, legally existing and 
in good standing under the laws of the jurisdiction of its incorporation if, 
in the case of Subsidiaries, the failure to be so organized, existing and in 
good standing would have a Material Adverse Effect; (ii) has all requisite 
corporate power, and has all material governmental licenses, authorizations, 
consents and approvals necessary in all material respects to own its assets 
and carry on its business as now being or as proposed to be conducted; and 
(iii) is qualified to do business in all jurisdictions in which the nature of 
the business conducted by it makes such qualification necessary and where 
failure so to qualify would have a Material Adverse Effect.

               Section 7.02  FINANCIAL CONDITION.  The unaudited consolidated 
balance sheet of the Borrower and its Consolidated Subsidiaries as at 
December 31, 1997 and the related consolidated statement of income, of the 
Borrower and its Consolidated Subsidiaries for the fiscal year ended on said 
date and the unaudited consolidated balance sheet of the Borrower and its 
Consolidated Subsidiaries as at September 30, 1998 and the related 
consolidated statement of income, of the Borrower and its Consolidated 
Subsidiaries for the nine month period ended on such date heretofore 
furnished to the Agent, are complete and correct and fairly present the 
consolidated financial condition of the Borrower and its Consolidated 
Subsidiaries as at said dates and the results of its operations for the 
fiscal year and the nine month period on said dates, all in accordance with 
GAAP (except that the financial statements of the Borrower need not contain 
footnotes or provisions for income taxes), as applied on a consistent basis 
(subject, in the case of the interim financial statements, to normal year-end 
adjustments).  Neither the Borrower nor any Subsidiary has on the Closing 
Date any material Debt, material contingent liabilities, material liabilities 
for taxes, material unusual forward or long-term commitments or material 
unrealized or anticipated losses from any unfavorable commitments, except as 
referred to or reflected or provided for in the Financial Statements or in 
SCHEDULE 7.02.  Other than the change in the general market price of oil and 
gas, since December 31, 1997, there has been no change or event having a 
Material Adverse Effect.  Since the date of the Financial Statements, neither 
the business nor the Properties of the Borrower or any material Subsidiary 
have been materially and adversely affected as a result of any fire, 
explosion, earthquake, flood, drought, windstorm, accident, strike or other 
labor disturbance, embargo, requisition or taking of Property or cancellation 
of contracts, permits or concessions by any Governmental Authority, riot, 
activities of armed forces or acts of God or of any public enemy. 

               Section 7.03  LITIGATION.  Except as disclosed to the Lenders 
in SCHEDULE 7.03 hereto, at the Closing Date there is no material litigation, 
legal, administrative or arbitral proceeding, investigation or other action 
of any nature pending or, to the knowledge of the Borrower threatened against 
the Borrower or any Subsidiary which involves the reasonable possibility of 
any judgment or liability against the Borrower or any Subsidiary not fully 
covered by insurance (except for normal deductibles).

               Section 7.04  NO BREACH.  Neither the execution and delivery 
of the Loan Documents, nor compliance with the terms and provisions hereof 
will conflict with or result in a breach of, or require any consent which has 
not been obtained as of the Closing Date under, the respective charter or 
by-laws of the Borrower or any Subsidiary, or any Governmental Requirement or 
any agreement or instrument to which the Borrower or any Subsidiary is a 
party or by which it is bound or to which 

                                      -41-
<PAGE>

it or its Properties are subject, or constitute a default under any such 
agreement or instrument, or result in the creation or imposition of any Lien 
upon any of the revenues or assets of the Borrower or any Subsidiary pursuant 
to the terms of any such agreement or instrument other than the Liens created 
by the Loan Documents.

               Section 7.05  AUTHORITY.  The Borrower has all necessary 
corporate power and authority to execute, deliver and perform its obligations 
under the Loan Documents to which it is a party; and the execution, delivery 
and performance by the Borrower of the Loan Documents to which it is a party, 
has been duly authorized by all necessary corporate action on its part; and 
the Loan Documents constitute the legal, valid and binding obligations of the 
Borrower, enforceable in accordance with their terms, except as limited by 
bankruptcy, insolvency, reorganization, moratorium or other similar laws of 
general application relating to or affecting creditor's rights and general 
principals of equity.

               Section 7.06  APPROVALS.  No authorizations, approvals or 
consents of, and no filings or registrations with, any Governmental Authority 
are necessary for the execution, delivery or performance by the Borrower of 
the Loan Documents or for the validity or enforceability thereof, except for 
the recording and filing of the Loan Documents as required by this Agreement 
and except in the case of performance (i) those matters customarily done 
after execution and (ii) those matters required in raising the Minimum 
Capital.

               Section 7.07  USE OF LOANS.  The proceeds of the Loans shall 
be used to finance the Amoco Acquisition, refinance existing bank debt and 
for working capital and general corporate purposes. The Borrower is not 
engaged principally, or as one of its important activities, in the business 
of extending credit for the purpose, whether immediate, incidental or 
ultimate, of buying or carrying margin stock (within the meaning of 
Regulation G, T, U or X of the Board of Governors of the Federal Reserve 
System) and no part of the proceeds of any Loan hereunder will be used to buy 
or carry any margin stock.

               Section 7.08  ERISA.  

               (a)    No act, omission or transaction has occurred with respect
       to any Plan which would have a Material Adverse Effect.

               (b)    No Plan (other than a defined contribution plan) or any
       trust created under any such Plan has been terminated since September 2,
       1974.  No liability to the PBGC (other than for the payment of current
       premiums which are not past due) by the Borrower, any Subsidiary or any
       ERISA Affiliate has been or is expected by the Borrower, any Subsidiary
       or any ERISA Affiliate to be incurred with respect to any Plan.  No
       ERISA Event with respect to any Plan has occurred that would have a
       Material Adverse Effect.

               (c)    Full payment when due has been made of all amounts which
       the Borrower, any Subsidiary or any ERISA Affiliate is required under
       the terms of each Plan or applicable law to have paid as contributions
       to such Plan, and no accumulated funding deficiency (as 

                                      -42-
<PAGE>

       defined in section 302 of ERISA and section 412 of the Code), whether 
       or not waived, exists with respect to any Plan.

               (d)    The actuarial present value of the benefit liabilities
       under each Plan which is subject to Title IV of ERISA does not, as of
       the end of the Borrower's most recently ended fiscal year, exceed the
       current value of the assets (computed on a plan termination basis in
       accordance with Title IV of ERISA) of such Plan allocable to such
       benefit liabilities.  The term "actuarial present value of the benefit
       liabilities" shall have the meaning specified in section 4041 of ERISA.

               (e)    None of the Borrower, any Subsidiary or any ERISA
       Affiliate sponsors, maintains, or contributes to an employee welfare
       benefit plan, as defined in section 3(1) of ERISA, including, without
       limitation, any such plan maintained to provide benefits to former
       employees of such entities, that may not be terminated by the Borrower,
       a Subsidiary or any ERISA Affiliate in its sole discretion at any time
       without any material liability.

               (f)    None of the Borrower, any Subsidiary or any ERISA
       Affiliate sponsors, maintains or contributes to, or has at any time in
       the preceding six calendar years, sponsored, maintained or contributed
       to, any Multiemployer Plan.

               (g)    None of the Borrower, any Subsidiary or any ERISA
       Affiliate is required to provide security under section 401(a)(29) of
       the Code due to a Plan amendment that results in an increase in current
       liability for the Plan.

               Section 7.09  TAXES.  Except as set out in SCHEDULE 7.09, each 
of the Borrower and its Subsidiaries has filed all United States Federal 
income tax returns and all other material tax returns which are required to 
be filed by them and have paid all material taxes due pursuant to such 
returns or pursuant to any assessment received by the Borrower or any 
Subsidiary.  The charges, accruals and reserves on the books of the Borrower 
and its Subsidiaries in respect of taxes and other governmental charges are, 
in the opinion of the Borrower, adequate.  No material tax lien (other than 
any Excepted Lien) has been filed and, to the knowledge of the Borrower, no 
material claim is being asserted with respect to any such tax, fee or other 
charge.

               Section 7.10  TITLES, ETC.  

               (a)    Except as set out in SCHEDULE 7.10, each of the Borrower
       and its material Subsidiaries has good and defensible title to its
       material (individually or in the aggregate) Properties, free and clear
       of all Liens, except Liens permitted by Section 9.02. Except as set
       forth in SCHEDULE 7.10, after giving full effect to the Excepted Liens,
       the Borrower (i) owns the net interests in production attributable to
       the Hydrocarbon Interests reflected in the most recently delivered
       Reserve Report and the ownership of such Properties shall not in any
       material respect obligate the Borrower to bear the costs and expenses
       relating to the maintenance, development and operations of each such
       Property in an amount in excess of the working interest of each Property
       set forth in the most recently delivered Reserve Report and (ii) the
       Borrower owns the net interests in production in the Amoco Properties
       set forth 

                                      -43-
<PAGE>

       in the Reserve Reports and such Properties shall not in any material 
       respect obligate the Borrower to bear the costs and expenses relating to 
       the maintenance, development and operations of each such Property in an 
       amount in excess of the working interest of each Property reflected in 
       the Reserve Reports.  All information contained in the most recently 
       delivered Reserve Report is true and correct in all material respects as 
       of the date thereof.

               (b)    All material leases and material agreements necessary for
       the conduct of the business of the Borrower and its Subsidiaries are
       valid and subsisting, in full force and effect and there exists no
       default or event or circumstance which with the giving of notice or the
       passage of time or both would give rise to a default under any such
       lease or leases, which would affect in any material respect the conduct
       of the business of the Borrower and its Subsidiaries.

               (c)    The rights, Properties and other assets presently owned,
       leased or licensed by the Borrower and its Subsidiaries including,
       without limitation, all easements and rights of way, include all rights,
       Properties and other assets necessary to permit the Borrower and its
       Subsidiaries to conduct their business with respect to the Amoco
       Properties acquired by the Borrower in all material respects in the same
       manner as its business has been conducted prior to the Closing Date.

               (d)    All of the assets and Properties of the Borrower and its
       material Subsidiaries which are reasonably necessary for the operation
       of its business are in good working condition in all material respects
       and are maintained in all material respects in accordance with prudent
       business standards.

               Section 7.11  NO MATERIAL MISSTATEMENTS.  No written 
information, statement, exhibit, certificate, document or report furnished to 
the Agent and the Lenders (or any of them) by the Borrower or any Subsidiary 
in connection with the negotiation of this Agreement contained any material 
misstatement of fact or omitted to state a material fact or any fact 
necessary to make the statement contained therein not materially misleading 
in the light of the circumstances in which made and with respect to the 
Borrower and its Subsidiaries taken as a whole.  It is understood that any 
financial or other future projections included in any such information are 
based upon Borrower's best available information and reasonable opinion and 
no warranty is hereby given with respect to such projections.  There is no 
fact peculiar to the Borrower or any Subsidiary which has a Material Adverse 
Effect or in the future is reasonably likely to have (so far as the Borrower 
can reasonably foresee as of the date hereof) a Material Adverse Effect and 
which has not been set forth in this Agreement or the other documents, 
certificates and statements furnished to the Agent by or on behalf of the 
Borrower or any Subsidiary prior to, or on, the Closing Date in connection 
with the transactions contemplated hereby.

               Section 7.12  INVESTMENT COMPANY ACT.  Neither the Borrower 
nor any Subsidiary is an "investment company" or a company "controlled" by an 
"investment company," within the meaning of the Investment Company Act of 
1940, as amended.

                                      -44-

               Section 7.13  PUBLIC UTILITY HOLDING COMPANY ACT.  Neither the 
Borrower nor any Subsidiary is a "holding company," or a "subsidiary company" 
of a "holding company," or an "affiliate" of a "holding company" or of a 
"subsidiary company" of a "holding company," or a "public utility" within the 
meaning of the Public Utility Holding Company Act of 1935, as amended.

               Section 7.14  SUBSIDIARIES.  Except as set forth on SCHEDULE 
7.14, the Borrower has no Subsidiaries.

               Section 7.15  LOCATION OF BUSINESS AND OFFICES.  The 
Borrower's principal place of business and chief executive offices are 
located at the address stated on the signature page of this Agreement.  The 
principal place of business and chief executive office of each Subsidiary are 
located at the addresses stated on SCHEDULE 7.14.

               Section 7.16  DEFAULTS.  Neither the Borrower nor any 
Subsidiary is in default nor has any event or circumstance occurred which, 
but for the expiration of any applicable grace period or the giving of 
notice, or both, would constitute a default under any material agreement or 
instrument to which the Borrower or any Subsidiary is a party or by which the 
Borrower or any Subsidiary is bound which default would have a Material 
Adverse Effect.  No Default hereunder has occurred and is continuing.

               Section 7.17  ENVIRONMENTAL MATTERS.  Except (i) as provided 
in SCHEDULE 7.17 or (ii) as would not have a Material Adverse Effect (or with 
respect to (c), (d) and (e) below, where the failure to take such actions 
would not have a Material Adverse Effect):

               (a)    Neither any Property of the Borrower or any Subsidiary
       nor the operations conducted thereon violate any order or requirement of
       any court or Governmental Authority or any Environmental Laws;

               (b)    Without limitation of clause (a) above, no Property of
       the Borrower or any Subsidiary nor the operations currently conducted
       thereon or, to the best knowledge of the Borrower, by any prior owner or
       operator of such Property or operation, are in violation of or subject
       to any existing, pending or threatened action, suit, investigation,
       inquiry or proceeding by or before any court or Governmental Authority
       or to any remedial obligations under Environmental Laws;

               (c)    All notices, permits, licenses or similar authorizations,
       if any, required to be obtained or filed in connection with the
       operation or use of any and all Property of the Borrower and each
       Subsidiary, including without limitation past or present treatment,
       storage, disposal or release of a hazardous substance or solid waste
       into the environment, have been duly obtained or filed, and the Borrower
       and each Subsidiary are in compliance with the terms and conditions of
       all such notices, permits, licenses and similar authorizations;

               (d)    All hazardous substances, solid waste, and oil and gas
       exploration and production wastes, if any, generated at any and all
       Property of the Borrower or any Subsidiary have in the past been
       transported, treated and disposed of in accordance with 

                                      -45-
<PAGE>

       Environmental Laws and so as not to pose an imminent and substantial 
       endangerment to public health or welfare or the environment, and, to the 
       best knowledge of the Borrower, all such transport carriers and treatment
       and disposal facilities have been and are operating in compliance with 
       Environmental Laws and so as not to pose an imminent and substantial 
       endangerment to public health or welfare or the environment, and are not 
       the subject of any existing, pending or threatened action, investigation 
       or inquiry by any Governmental Authority in connection with any 
       Environmental Laws;

               (e)    The Borrower has taken all steps reasonably necessary to
       determine and has determined that no hazardous substances, solid waste,
       or oil and gas exploration and production wastes, have been disposed of
       or otherwise released and there has been no threatened release of any
       hazardous substances on or to any Property of the Borrower or any
       Subsidiary except in compliance with Environmental Laws and so as not to
       pose an imminent and substantial endangerment to public health or
       welfare or the environment;

               (f)    To the extent applicable, all Property of the Borrower
       and each Subsidiary currently satisfies all design, operation, and
       equipment requirements imposed by the OPA or scheduled as of the Closing
       Date to be imposed by OPA during the term of this Agreement, and the
       Borrower does not have any reason to believe that such Property, to the
       extent subject to OPA, will not be able to maintain compliance with the
       OPA requirements during the term of this Agreement; and

               (g)    Neither the Borrower nor any Subsidiary has any known
       contingent liability in connection with any release or threatened
       release of any oil, hazardous substance or solid waste into the
       environment.

               Section 7.18  COMPLIANCE WITH THE LAW.  Neither the Borrower 
nor any Subsidiary has violated any Governmental Requirement or failed to 
obtain any license, permit, franchise or other governmental authorization 
necessary for the ownership of any of its Properties or the conduct of its 
business, which violation or failure would have (in the event such violation 
or failure were asserted by any Person through appropriate action) a Material 
Adverse Effect. Except for such acts or failures to act as would not have a 
Material Adverse Effect, the Borrower's Oil and Gas Properties (and 
properties unitized therewith) have been maintained, operated and developed 
in a good and workmanlike manner and in conformity with all applicable laws 
and all rules, regulations and orders of all duly constituted authorities 
having jurisdiction and in conformity with the provisions of all leases, 
subleases or other contracts comprising a part of the Hydrocarbon Interests 
and other contracts and agreements forming a part of the Borrower's Oil and 
Gas Properties; specifically in this connection, (i) after the Closing Date, 
no Oil and Gas Property of the Borrower is subject to having allowable 
production materially reduced below the full and regular allowable (including 
the maximum permissible tolerance) because of any overproduction (whether or 
not the same was permissible at the time) prior to the Closing Date and (ii) 
none of the wells comprising a part of the Borrower's Oil and Gas Properties 
(or properties unitized therewith) are deviated from the vertical more than 
the maximum permitted by applicable laws, regulations, rules and orders, and 
such wells are, in fact, bottomed under and are producing from, and the well 
bores are wholly within, the 

                                      -46-


<PAGE>

Borrower's Oil and Gas Properties (or in the case of wells located on 
properties unitized therewith, such unitized properties).

               Section 7.19  INSURANCE.  SCHEDULE 7.19 attached hereto 
contains an accurate and complete description of all material policies of 
fire, liability, workmen's compensation and other forms of insurance owned or 
held by the Borrower and each Subsidiary.  All such policies are in full 
force and effect, all premiums that are due with respect thereto covering all 
periods up to and including the Closing Date have been paid, and no notice of 
cancellation or termination has been received with respect to any such 
policy.  Such policies are sufficient, in all material respects, for 
compliance with all requirements of law and of all agreements to which the 
Borrower or any Subsidiary is a party; are valid, outstanding and enforceable 
policies; provide adequate insurance coverage in at least such amounts and 
against at least such risks (but including in any event public liability) as 
are usually insured against in the same general area by companies engaged in 
the same or a similar business for the assets and operations of the Borrower 
and each Subsidiary; will remain in full force and effect through the 
respective dates set forth in SCHEDULE 7.19 without the payment of additional 
premiums except those which are not yet due; and will not in any way be 
affected by, or terminate or lapse by reason of, the transactions 
contemplated by this Agreement.  SCHEDULE 7.19 identifies all material risks, 
if any, which the Borrower and its Subsidiaries and their respective Board of 
Directors or officers have designated as being self insured. Neither the 
Borrower nor any Subsidiary has been refused any insurance with respect to 
its assets or operations, nor has its coverage been limited below usual and 
customary policy limits, by an insurance carrier to which it has applied for 
any such insurance or with which it has carried insurance during the last 
three years.

               Section 7.20  HEDGING AGREEMENTS.  SCHEDULE 7.20 sets forth, 
as of the Closing Date, a true and complete list of all Hedging Agreements of 
the Borrower and each Subsidiary, the material terms thereof (including the 
type, term, effective date, termination date and notional amounts or 
volumes), the net mark to market value thereof, all credit support agreements 
relating thereto (including any margin required or supplied), and the counter 
party to each such agreement.

               Section 7.21  RESTRICTION ON LIENS.  Neither the Borrower nor 
any of its Subsidiaries is a party to any agreement or arrangement (other 
than this Agreement and the other Loan Documents), or subject to any order, 
judgment, writ or decree, which either restricts or purports to restrict its 
ability to grant Liens to other Persons on or in respect of their respective 
assets or Properties other than those permitted by Section 9.19 hereof. 

               Section 7.22  MATERIAL AGREEMENTS. Set forth on SCHEDULE 7.22 
hereto is a complete and correct list of all material agreements, leases, 
indentures, purchase agreements, obligations in respect of letters of credit, 
guarantees, joint venture agreements, and other instruments in effect or to 
be in effect as of the Closing Date (other than Hedging Agreements) providing 
for, evidencing, securing or otherwise relating to any Debt as defined in 
clauses (i), (ii), (iv), (v), (vi), (vii) and (xii) of the definition thereof 
of the Borrower or any of its Subsidiaries, and all obligations in effect on 
the Closing Date of the Borrower or any of its Subsidiaries to issuers of 
surety or appeal bonds issued for the account of the Borrower or any such 
Subsidiary, and such list correctly sets forth the names of the debtor or 
lessee and creditor or lessor with respect to the Debt or lease obligations

outstanding or to be outstanding and the Property subject to any Lien 
securing such Debt or lease obligation.  
                                       
                                  ARTICLE VIII

                              AFFIRMATIVE COVENANTS

of each for the Lenders:

       each case in comparative form the corresponding figures for the
       preceding fiscal year, and accompanied by the related opinion of
       independent public accountants of recognized national standing which
       opinion shall state that said financial statements fairly present the
       consolidated and consolidating financial condition and results of
       operations of the Guarantor and its Consolidated Subsidiaries as at the
       end of, and for, such fiscal year and that such financial statements
       have been prepared in accordance with GAAP, except for such changes in
       such principles with which the independent public accountants shall have
       concurred and such opinion shall not contain a "going concern" or like
       qualification or exception.

               (b)    QUARTERLY FINANCIAL STATEMENTS.  As soon as available and
       in any event within 60 days after the end of each of the first three
       fiscal quarterly periods of each fiscal year of the Guarantor,

       to normal year-end audit adjustments).

               (c)    NOTICE OF DEFAULT, ETC.  Promptly after the Borrower
       knows that any Default (other than with respect to Section 8.01) or any
       Material Adverse Effect has occurred, a

       notice of such Default or Material Adverse Effect, describing the same

               (a)    Not less than 60 days prior to each Scheduled

       prepared by or under the supervision of the chief engineer of the

       to the certificate, on a net basis there are no gas imbalances, take or
       pay or other prepayments with respect to its Oil and Gas Properties
       evaluated in such Reserve Report which would require the Borrower to
       deliver Hydrocarbons produced from such Oil and Gas Properties at some
       future time without then or thereafter receiving full payment therefor,
       (iv) none of its Oil and Gas Properties have been sold since the date of
       the last Borrowing Base determination except as set forth on an exhibit

       and Gas Properties added to and deleted from the immediately prior

       from its Oil and Gas Properties and (vii) 80% of all of the Oil and Gas 
       Properties evaluated by such Reserve Report will be Mortgaged Property.

               Section 8.08  TITLE AND MORTGAGE INFORMATION.

               (a)    DELIVERY.  On or before the delivery to the Agent and the
       Lenders of each Reserve Report required by Section 8.07(a), the Borrower
       will deliver title information in form and substance acceptable to the
       Agent covering enough of the Oil and Gas Properties evaluated by such
       Reserve Report that were not included in the immediately preceding
       Reserve Report, so that the Agent shall have received together with
       title information and Liens previously delivered to the Agent,
       satisfactory title information on at least eighty percent (80%) of the
       value of the Oil and Gas Properties evaluated by such Reserve Report.

               (b)    CURE OF TITLE DEFECTS.  The Borrower shall cure any title
       defects or exceptions which are not Excepted Liens raised by such
       information or substitute acceptable Mortgaged Properties with no title
       defects or exceptions except for Excepted Liens, covering Mortgaged
       Properties of an equivalent value, within 45 days after a request by the
       Agent or the Lenders to cure such defects or exceptions.

               (c)    FAILURE TO CURE TITLE DEFECTS.  If the Borrower is unable
       to cure any title defect requested by the Agent or the Lenders to be
       cured or the Borrower does not comply with the requirement to provide
       acceptable title information covering eighty percent (80%) of the value
       of the Oil and Gas Properties evaluated in the most recent Reserve
       Report, such default shall not be a Default or an Event of Default, but
       instead the Agent and the Lenders shall have the right to exercise the
       following remedy in their sole discretion from time to time, and any
       failure to so exercise this remedy at any time shall not be a waiver as
       to future exercise of the remedy by the Agent or the Lenders.  To the
       extent that the Agent or the Lenders are not satisfied with title to any
       Oil and Gas Property after the time period in Section 8.08(b) has
       elapsed, such unacceptable Oil and Gas Property shall not count towards
       the eighty percent (80%) requirement, and the Agent may send a notice to
       the Borrower and the Lenders that the then outstanding Borrowing Base
       shall be reduced by an amount as determined by all of the Lenders to
       cause the Borrower to be in compliance with the requirement to provide
       acceptable title information on eighty percent (80%) of the value of the
       Oil and Gas Properties.  This new Borrowing Base shall become effective
       immediately after receipt of such notice.

               Section 8.09   ADDITIONAL MORTGAGES.

<PAGE>
                                       
               (a)    The Borrower will grant to the Agent as security for the
       Indebtedness a first-priority Lien interest (subject only to Excepted
       Liens) on the Borrower's interest in those Oil and Gas Properties listed
       on Schedule 8.09 in sufficient time to permit appropriate filing by
       January 31, 1999.  The Borrower will grant to the Agent first-priority
       Lien interests (subject only to Excepted Liens) on its interest on at
       least eighty percent (80%) of the value of the Oil and Gas Properties
       evaluated by the most recent Reserve Report.  Such Liens will be created
       and perfected by and in accordance with the provisions of the Mortgages,
       all in form and substance satisfactory to the Agent in its sole
       discretion and in sufficient executed (and acknowledged where necessary
       or appropriate) counterparts for recording purposes.

               (b)    Concurrently with the granting of the Lien or other
       action referred to in Section 8.09(a) above, the Borrower will provide
       to the Agent title information in form and substance satisfactory to the
       Agent in its sole discretion with respect to the Borrower's interests in
       such assets.

               (c)    Promptly after the filing of any new Loan Document
       pursuant to clause (a) above in any state, upon the reasonable request
       of the Agent, the Borrower will provide to the Agent an opinion
       addressed to the Agent for the benefit of the Lenders in form and
       substance satisfactory to the Agent in its sole discretion from counsel
       acceptable to Agent, stating that such Loan Document is valid, binding
       and enforceable in accordance with its terms and in legally sufficient
       form for such jurisdiction.

               Section 8.10  ERISA INFORMATION AND COMPLIANCE.  The Borrower 
will promptly furnish and will cause the Subsidiaries and any ERISA Affiliate 
to promptly furnish to the Agent with sufficient copies to the Lenders (i) 
immediately upon becoming aware of the occurrence of any ERISA Event or 
breach or violation of or default by the Borrower or any Subsidiary under any 
Plan which, individually or in the aggregate, would have a Material Adverse 
Effect, a written notice signed by a Responsible Officer specifying the 
nature thereof, what action the Borrower, the Subsidiary or the ERISA 
Affiliate is taking or proposes to take with respect thereto, and, when 
known, any action taken or proposed by the Internal Revenue Service, the 
Department of Labor or the PBGC with respect thereto, and (ii) immediately 
upon receipt thereof, copies of any notice of the PBGC's intention to 
terminate or to have a trustee appointed to administer any Plan.  With 
respect to each Plan (other than a Multiemployer Plan), the Borrower will,

and in a timely manner, without incurring any late payment or underpayment 
charge or penalty and without giving rise to any lien, all of the 
contribution and funding requirements of section 412 of the Code (determined 
without regard to subsections (d), (e), (f) and (k) thereof) and of section 
302 of ERISA (determined without regard to sections 303, 304 and 306 of 
ERISA), and (ii) pay, or cause to be paid, to the PBGC in a timely manner, 
without incurring any late payment or underpayment charge or penalty, all 
premiums required pursuant to sections 4006 and 4007 of ERISA.

               Section 8.11  MINIMUM CAPITAL. By May 30, 1999, the Borrower 
shall raise not less than $30,000,000 from:

                                    THE AGENT

               Section 11.01  APPOINTMENT, POWERS AND IMMUNITIES.  Each 
Lender hereby irrevocably appoints and authorizes the Agent to act as its 
agent hereunder and under the other Loan Documents with such powers as are 
specifically delegated to the Agent by the terms of the Loan Documents, 
together with such other powers as are reasonably incidental thereto.  The 
Agent (which term as used in this sentence and in Section 11.05 and the first 
sentence of Section 11.06 shall include reference to its Affiliates and its 
and its Affiliates' officers, directors, employees, attorneys, accountants, 
experts and agents):  (i) shall have no duties or responsibilities except 
those expressly set forth in the Loan Documents, and shall not by reason of 
the Loan Documents be a trustee or fiduciary for any Lender; (ii) makes no 
representation or warranty to any Lender and shall not be responsible to the 
Lenders for any recitals, statements, representations or warranties contained 
in this Agreement, or in any certificate or other document referred to or 
provided for in, or received by any of them under, this Agreement, or for the 
value, validity, effectiveness, genuineness, execution, effectiveness, 
legality, enforceability or sufficiency of this Agreement, any Note or any 
other document referred to or provided for herein or for any failure by the 
Borrower or any other Person (other than the Agent) to perform any of its 
obligations hereunder or thereunder or for the existence, value, perfection 
or priority of any collateral security or the financial or other condition of 
the Borrower, its Subsidiaries or any other obligor or guarantor; (iii) 
except pursuant to Section 11.07 shall not be required to initiate or conduct 
any litigation or collection proceedings hereunder; and (iv) shall not be 
responsible for any action taken or omitted to be taken by it hereunder or 
under any other document or instrument referred to or provided for herein or 
in connection herewith including its own ordinary negligence, except for its 
own gross negligence or willful misconduct.  The Agent may employ agents, 
accountants, attorneys and experts and shall not be responsible for the 
negligence or misconduct of any such agents, accountants, attorneys or 
experts selected by it in good faith or any action taken or omitted to be 
taken in good faith by it in accordance with the advice of such agents, 
accountants, attorneys or experts.  The Agent may deem and treat the payee of 
any Note as the holder thereof for all purposes hereof unless and until a 
written notice of the assignment or transfer thereof permitted hereunder 
shall have been filed with the Agent.  The Agent is authorized to release any 
collateral that is permitted to be sold or released pursuant to the terms of 
the Loan Documents.  The Lenders and the Borrower agree that the Syndication 
Agent and the Documentation Agent shall have no duties or obligations in 
their respective capacities.

               Section 11.02  RELIANCE BY AGENT.  The Agent shall be entitled 
to rely upon any certification, notice or other communication (including any 
thereof by telephone, telex, telecopier, telegram or cable) believed by it to 
be genuine and correct and to have been signed or sent by or on behalf of the 
proper Person or Persons, and upon advice and statements of legal counsel, 
independent accountants and other experts selected by the Agent. 

               Section 11.03  DEFAULTS.  The Agent shall not be deemed to 
have knowledge of the occurrence of a Default (other than the non-payment of 
principal of or interest on Loans or of fees or failure to reimburse for 
Letter of Credit drawings) unless the Agent has received notice from a Lender 
or the Borrower specifying such Default and stating that such notice is a 
"Notice of Default."  
                                       


                                      -65-

<PAGE>
                                       
In the event that the Agent receives such a notice of the occurrence of a 
Default, the Agent shall give prompt notice thereof to the Lenders.  In the 
event of a payment Default, the Agent shall give each Lender prompt notice of 
each such payment Default.

               Section 11.04  RIGHTS AS A LENDER.  With respect to its 
Commitments and the Loans made by it and its participation in the issuance of 
Letters of Credit, BMO (and any successor acting as Agent) in its capacity as 
a Lender hereunder shall have the same rights and powers hereunder as any 
other Lender and may exercise the same as though it were not acting as the 
Agent, and the term "Lender" or "Lenders" shall, unless the context otherwise 
indicates, include the Agent in its individual capacity.  BMO (and any 
successor acting as Agent) and its Affiliates may (without having to account 
therefor to any Lender) accept deposits from, lend money to and generally 
engage in any kind of banking, trust or other business with the Borrower (and 
any of its Affiliates) as if it were not acting as the Agent, and BMO and its 
Affiliates may accept fees and other consideration from the Borrower for 
services in connection with this Agreement or otherwise without having to 
account for the same to the Lenders.

               Section 11.05  INDEMNIFICATION.  THE LENDERS AGREE TO 
INDEMNIFY THE AGENT AND THE ISSUING BANK RATABLY IN ACCORDANCE WITH THEIR 
PERCENTAGE SHARES FOR THE INDEMNITY MATTERS AS DESCRIBED IN SECTION 12.03 TO 
THE EXTENT NOT INDEMNIFIED OR REIMBURSED BY THE BORROWER UNDER SECTION 12.03, 
BUT WITHOUT LIMITING THE OBLIGATIONS OF THE BORROWER UNDER SAID SECTION 12.03 
AND FOR ANY AND ALL OTHER LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, 
PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS OF ANY 
KIND AND NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED BY OR ASSERTED 
AGAINST THE AGENT OR THE ISSUING BANK IN ANY WAY RELATING TO OR ARISING OUT 
OF: (I) THIS AGREEMENT, THE OTHER LOAN DOCUMENTS OR ANY OTHER DOCUMENTS 
CONTEMPLATED BY OR REFERRED TO HEREIN OR THE TRANSACTIONS CONTEMPLATED 
HEREBY, BUT EXCLUDING, UNLESS A DEFAULT HAS OCCURRED AND IS CONTINUING, 
NORMAL ADMINISTRATIVE COSTS AND EXPENSES INCIDENT TO THE PERFORMANCE OF ITS 
AGENCY DUTIES HEREUNDER OR (II) THE ENFORCEMENT OF ANY OF THE TERMS OF THIS 
AGREEMENT, ANY OTHER LOAN DOCUMENTS OR OF ANY SUCH OTHER DOCUMENTS; WHETHER 
OR NOT ANY OF THE FOREGOING SPECIFIED IN THIS SECTION 11.05 ARISES FROM THE 
SOLE OR CONCURRENT NEGLIGENCE OF THE AGENT OR THE ISSUING BANK, PROVIDED THAT 
NO LENDER SHALL BE LIABLE FOR ANY OF THE FOREGOING TO THE EXTENT THEY ARISE 
FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE AGENT.

               Section 11.06  NON-RELIANCE ON AGENT AND OTHER LENDERS.  Each 
Lender acknowledges and agrees that it has, independently and without 
reliance on the Agent or any other Lender, and based on such documents and 
information as it has deemed appropriate, made its own credit analysis of the 
Borrower and its decision to enter into this Agreement, and that it will, 
independently and without reliance upon the Agent or any other Lender, and 
based on such documents and information as it shall deem appropriate at the 
time, continue to make its own analysis and decisions in taking or not taking 
action under this Agreement. The Agent shall not be required to keep itself 
informed as to the performance or observance by the Borrower of this 
Agreement, the Notes, the other Loan Documents or any other document referred 
to or provided for herein or to inspect the properties or books of the 
Borrower.  Except for notices, reports and other

documents and information expressly required to be furnished to the Lenders 
by the Agent hereunder, the Agent shall not have any duty or responsibility 
to provide any Lender with any credit or other information concerning the 
affairs, financial condition or business of the Borrower (or any of its 
Affiliates) which may come into the possession of the Agent or any of its 
Affiliates.  In this regard, each Lender acknowledges that Vinson & Elkins 
L.L.P. is acting in this transaction as special counsel to the Agent only, 
except to the extent otherwise expressly stated in any legal opinion or any 
Loan Document.  Each Lender will consult with its own legal counsel to the 
extent that it deems necessary in connection with the Loan Documents and the 
matters contemplated therein.

               Section 11.07  ACTION BY AGENT.  Except for action or other 
matters expressly required of the Agent hereunder, the Agent shall in all 
cases be fully justified in failing or refusing to act hereunder unless it 
shall (i) receive written instructions from the Majority Lenders (or all of 
the Lenders as expressly required by Section 12.04) specifying the action to 
be taken, and (ii) be indemnified to its satisfaction by the Lenders against 
any and all liability and expenses which may be incurred by it by reason of 
taking or continuing to take any such action.  The instructions of the 
Majority Lenders (or all of the Lenders as expressly required by Section 
12.04) and any action taken or failure to act pursuant thereto by the Agent 
shall be binding on all of the Lenders.  If a Default has occurred and is 
continuing, the Agent shall take such action with respect to such Default as 
shall be directed by the Majority Lenders (or all of the Lenders as required 
by Section 12.04) in the written instructions (with indemnities) described in 
this Section 11.07, provided that, unless and until the Agent shall have 
received such directions, the Agent may (but shall not be obligated to) take 
such action, or refrain from taking such action, with respect to such Default 
as it shall deem advisable in the best interests of the Lenders. In no event, 
however, shall the Agent be required to take any action which exposes the 
Agent to personal liability or which is contrary to this Agreement and the 
other Loan Documents or applicable law.

               Section 11.08  RESIGNATION OR REMOVAL OF AGENT.  Subject to 
the appointment and acceptance of a successor Agent as provided below, the 
Agent may resign at any time by giving notice thereof to the Lenders and the 
Borrower, and the Agent may be removed at any time with or without cause by 
the Majority Lenders.  Upon any such resignation or removal, the Majority 
Lenders shall have the right to appoint a successor Agent subject to the 
approval of the Borrower, which approval may not be unreasonably withheld.  
If no successor Agent shall have been so appointed by the Majority Lenders 
and shall have accepted such appointment within thirty (30) days after the 
retiring Agent's giving of notice of resignation or the Majority Lenders' 
removal of the retiring Agent, then the retiring Agent may, on behalf of the 
Lenders, appoint a successor Agent.  Upon the acceptance of such appointment 
hereunder by a successor Agent, such successor Agent shall thereupon succeed 
to and become vested with all the rights, powers, privileges and duties of 
the retiring Agent, and the retiring Agent shall be discharged from its 
duties and obligations hereunder.  After any retiring Agent's resignation or 
removal hereunder as Agent, the provisions of this Article XI and Section 
12.03 shall continue in effect for its benefit in respect of any actions 
taken or omitted to be taken by it while it was acting as the Agent.

                                  MISCELLANEOUS

               Section 12.01  WAIVER.  No failure on the part of the Agent or 
any Lender to exercise and no delay in exercising, and no course of dealing 
with respect to, any right, power or privilege under any of the Loan 
Documents shall operate as a waiver thereof, nor shall any single or partial 
exercise of any right, power or privilege under any of the Loan Documents 
preclude any other or further exercise thereof or the exercise of any other 
right, power or privilege. The remedies provided herein are cumulative and 
not exclusive of any remedies provided by law.

               Section 12.02  NOTICES.  All notices and other communications

Agreement or the other Loan Documents) shall be given or made by telex,

notice to each other party.  Except as otherwise provided in this Agreement 
or in the other Loan Documents, all such communications shall be deemed to 
have been duly given when transmitted, if transmitted before 1:00 p.m. local 
time on a Business Day (otherwise on the next succeeding Business Day) by 
telex or telecopier and evidence or confirmation of receipt is obtained, or 
personally delivered or, in the case of a mailed notice, three (3) Business 
Days after the date deposited in the mails, postage prepaid, in each case

       MORTGAGEE-IN-POSSESSION OR OTHERWISE).

               (b)    No Indemnified Party may settle any claim to be
       indemnified without the consent of the indemnitor, such consent not to
       be unreasonably withheld; provided, that the indemnitor may not

       proposes, if the indemnitor does not have the financial ability to pay
       all its obligations outstanding and asserted against the indemnitor at
       that time, including the maximum potential claims against the
       Indemnified Party to be indemnified pursuant to this Section 12.03.

               (c)    In the case of any indemnification hereunder, the Agent

payable to the Lenders generally, affects Section 2.03(a), this Section 12.04 
or Section 12.06(a) or modifies the definition of "Majority Lenders" shall be

consent of the Agent.

               Section 12.05  SUCCESSORS AND ASSIGNS.  This Agreement shall 
be binding upon and inure to the benefit of the parties hereto and their 
respective successors and permitted assigns.

               Section 12.06  ASSIGNMENTS AND PARTICIPATIONS.

               (a)    The Borrower may not assign its rights or obligations
       hereunder or under the Notes or any Letters of Credit without the prior
       consent of all of the Lenders and the Agent.

               (b)    Any Lender may, upon the written consent of the Agent
       and, if no Event of Default has occurred and is continuing, the Borrower
       (which consent will not be unreasonably withheld), assign to one or more
       assignees all or a portion of its rights and obligations under this
       Agreement pursuant to an Assignment Agreement substantially in the form
       of EXHIBIT E (an "ASSIGNMENT"); PROVIDED, HOWEVER, that (i) any such
       assignment shall be in the amount of at least $10,000,000 or such lesser
       amount to which the Borrower has consented and (ii) the assignee or
       assignor shall pay to the Agent a processing and recordation fee of
       $3,500 for each assignment.  Any such assignment will become effective
       upon the execution and delivery to the Agent of the Assignment and the
       consent of the Agent.  Promptly after receipt of an executed Assignment,
       the Agent shall send to the Borrower a copy of such executed Assignment. 
       Upon receipt of such executed Assignment, the Borrower, will, at its own
       expense, execute and deliver new Notes to the assignor and/or assignee,
       as appropriate, in accordance with their respective interests as they
       appear.  Upon the effectiveness of any assignment pursuant to this
       Section 12.06(b), the assignee will become a "Lender," if not already a
       "Lender," for all purposes of this Agreement and the other Loan
       Documents.  The assignor shall be relieved of its obligations hereunder
       to the extent of such assignment (and if the assigning Lender no longer
       holds any rights or obligations under this Agreement, such assigning
       Lender shall cease to be a "Lender" hereunder except that its rights
       under Sections 4.06, 5.01, 5.05 and 12.03 shall not be affected).  The
       Agent will prepare on the last Business Day of each month during which
       an assignment has become effective pursuant to this Section 12.06(b), a
       new ANNEX I giving effect to all such assignments effected during such
       month, and will promptly provide the same to the Borrower and each of
       the Lenders.  

               (c)    Each Lender may transfer, grant or assign participations
       in all or any part of such Lender's interests hereunder pursuant to this
       Section 12.06(c) to any Person, PROVIDED

       that: (i) such Lender shall remain a "Lender" for all purposes of this 
       Agreement and the transferee of such participation shall not 
       constitute a "Lender" hereunder; and (ii) no participant under any 
       such participation shall have rights to approve any amendment to or 
       waiver of any of the Loan Documents except to the extent such 
       amendment or waiver would (x) forgive any principal owing on any 
       Indebtedness or extend the final maturity of the Loans, (y) reduce the 
       interest rate (other than as a result of waiving the applicability of 
       any post-default increases in interest rates) or fees applicable to 
       any of the Commitments or Loans or Letters of Credit in which such 
       participant is participating, or postpone the payment of any thereof, 
       or (z) release any guarantor of the Indebtedness or release all or 
       substantially all of the collateral (except as provided in the Loan 
       Documents) supporting any of the Commitments or Loans or Letters of 
       Credit in which such participant is participating.  In the case of any 
       such participation, the participant shall not have any rights under 
       this Agreement or any of the Loan Documents (the participant's rights 
       against the granting Lender in respect of such participation to be 
       those set forth in the agreement with such Lender creating such 
       participation), and all amounts payable by the Borrower hereunder 
       shall be determined as if such Lender had not sold such participation, 
       PROVIDED that such participant shall be entitled to receive additional 
       amounts under Article V on the same basis as if it were a Lender and 
       be indemnified under Section 12.03 as if it were a Lender.  In 
       addition, each agreement creating any participation must include an 
       agreement by the participant to be bound by the provisions of Section 
       12.15.

               (d)    The Lenders may furnish any information concerning the
       Borrower in the possession of the Lenders from time to time to assignees
       and participants (including prospective assignees and participants);
       provided that, such Persons agree to be bound by the provisions of
       Section 12.15.

               (e)    Notwithstanding anything in this Section 12.06 to the
       contrary, any Lender may assign and pledge all or any of its Notes to
       any Federal Reserve Bank as collateral security pursuant to Regulation A
       of the Board of Governors of the Federal Reserve System and any
       operating circular issued by such Federal Reserve System and/or such
       Federal Reserve Bank.  No such assignment and/or pledge shall release
       the assigning and/or pledging Lender from its obligations hereunder.

               (f)    Notwithstanding any other provisions of this Section
       12.06, no transfer or assignment of the interests or obligations of any
       Lender or any grant of participations therein shall be permitted if such
       transfer, assignment or grant would require the Borrower to file a
       registration statement with the SEC or to qualify the Loans under the
       "Blue Sky" laws of any state.

               Section 12.07  INVALIDITY.  In the event that any one or more of
the provisions contained in any of the Loan Documents or the Letters of Credit,
the Letter of Credit Agreements shall, for any reason, be held invalid, illegal
or unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provision of the Notes, this Agreement or any other
Loan Documents.

in any number of counterparts, all of which taken together shall constitute 
one and the same instrument and any of the parties hereto may execute this 
Agreement by signing any such counterpart.

herein.  Any reference herein to an exhibit or schedule shall be deemed to

               Section 12.10  SURVIVAL. The obligations of the parties under 
Section 4.06, Article V, and Sections 11.05 and 12.03 shall survive the 
repayment of the Loans and the termination of the Commitments.  To the extent 
that any payments on the Indebtedness or proceeds of any collateral are 
subsequently invalidated, declared to be fraudulent or preferential, set 
aside or required to be repaid to a trustee, debtor in possession, receiver 
or other Person under any bankruptcy law, common law or equitable cause, then 
to such extent, the Indebtedness so satisfied shall be revived and continue 
as if such payment or proceeds had not been received and the Agent's and the 
Lenders' Liens, security interests, rights, powers and remedies under this 
Agreement and each other Loan Document shall continue in full force and 
effect.  In such event, each Loan Document shall be automatically reinstated 
and the Borrower shall take such action as may be reasonably requested by the 
Agent and the Lenders to effect such reinstatement.

               (b)    ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN
       DOCUMENTS SHALL BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF THE
       UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF TEXAS, AND, BY
       EXECUTION AND DELIVERY OF THIS AGREEMENT, THE BORROWER HEREBY ACCEPTS
       FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS
       PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE
       AFORESAID COURTS.  THE BORROWER HEREBY IRREVOCABLY WAIVES ANY OBJECTION,
       INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR
       BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR
       HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH
       RESPECTIVE JURISDICTIONS.  THIS SUBMISSION TO JURISDICTION IS
       NON-EXCLUSIVE AND DOES NOT PRECLUDE THE AGENT OR ANY LENDER FROM
       OBTAINING JURISDICTION OVER THE BORROWER IN ANY COURT OTHERWISE HAVING
       JURISDICTION.

               (c)  NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE AGENT OR ANY
       LENDER OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER
       PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED
       AGAINST THE BORROWER IN ANY OTHER JURISDICTION.

               (d)    THE BORROWER AND EACH LENDER HEREBY (I) IRREVOCABLY AND
       UNCONDITIONALLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, TRIAL BY
       JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY
       LOAN DOCUMENTS AND FOR ANY COUNTERCLAIM THEREIN; (II) IRREVOCABLY WAIVE,
       TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO
       CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE
       OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO,
       ACTUAL DAMAGES; (III) CERTIFY THAT NO PARTY HERETO NOR ANY
       REPRESENTATIVE OR AGENT OF COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED,
       EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE
       EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (IV)
       ACKNOWLEDGE THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE
       LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY,
       AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN
       THIS SECTION 12.13.

               Section 12.14  INTEREST.  It is the intention of the parties
hereto that each Lender shall conform strictly to usury laws applicable to it. 
Accordingly, if the transactions contemplated hereby would be usurious as to any
Lender under laws applicable to it (including the laws of the United States of
America and the State of Texas or any other jurisdiction whose laws may be
mandatorily applicable to such Lender notwithstanding the other provisions of
this Agreement), then, in that event, notwithstanding anything to the contrary
in any of the Loan Documents or any agreement entered into in connection with or
as security for the Notes, it is agreed as follows:  (i) the aggregate of all
consideration which constitutes interest under law applicable to any Lender that
is contracted for, taken, reserved, charged or received by such Lender under any
of the Loan Documents or agreements or otherwise in connection with the Notes
shall under no circumstances exceed the maximum amount allowed by such
applicable law, and any excess shall be canceled automatically 


                                    -74-
<PAGE>

and if theretofore paid shall be credited by such Lender on the principal 
amount of the Indebtedness (or, to the extent that the principal amount of 
the Indebtedness shall have been or would thereby be paid in full, refunded 
by such Lender to the Borrower); and (ii) in the event that the maturity of 
the Notes is accelerated by reason of an election of the holder thereof 
resulting from any Event of Default under this Agreement or otherwise, or in 
the event of any required or permitted prepayment, then such consideration 
that constitutes interest under law applicable to any Lender may never 
include more than the maximum amount allowed by such applicable law, and 
excess interest, if any, provided for in this Agreement or otherwise shall be 
canceled automatically by such Lender as of the date of such acceleration or 
prepayment and, if theretofore paid, shall be credited by such Lender on the 
principal amount of the Indebtedness (or, to the extent that the principal 
amount of the Indebtedness shall have been or would thereby be paid in full, 
refunded by such Lender to the Borrower).  All sums paid or agreed to be paid 
to any Lender for the use, forbearance or detention of sums due hereunder 
shall, to the extent permitted by law applicable to such Lender, be 
amortized, prorated, allocated and spread throughout the full term of the 
Loans evidenced by the Notes until payment in full so that the rate or amount 
of interest on account of any Loans hereunder does not exceed the maximum 
amount allowed by such applicable law.  If at any time and from time to time 
(i) the amount of interest payable to any Lender on any date shall be 
computed at the Highest Lawful Rate applicable to such Lender pursuant to 
this Section 12.14 and (ii) in respect of any subsequent interest computation 
period the amount of interest otherwise payable to such Lender would be less 
than the amount of interest payable to such Lender computed at the Highest 
Lawful Rate applicable to such Lender, then the amount of interest payable to 
such Lender in respect of such subsequent interest computation period shall 
continue to be computed at the Highest Lawful Rate applicable to such Lender 
until the total amount of interest payable to such Lender shall equal the 
total amount of interest which would have been payable to such Lender if the 
total amount of interest had been computed without giving effect to this 
Section 12.14.  To the extent that Article 5069-1.04 of the Texas Revised 
Civil Statutes is relevant for the purpose of determining the Highest Lawful 
Rate, such Lender elects to determine the applicable rate ceiling under such 
Article by the indicated weekly rate ceiling from time to time in effect.

               Section 12.15  CONFIDENTIALITY.  In the event that the Borrower
provides to the Agent or the Lenders written confidential information belonging
to the Borrower or Guarantor or any Subsidiary thereof (hereinafter called the
"Subject Entities"), the Agent and the Lenders shall thereafter maintain such
information in confidence in accordance with the standards of care and diligence
that each utilizes in maintaining its own confidential information.  This
obligation of confidence shall not apply to such portions of the information
which (i) are in the public domain, (ii) hereafter become part of the public
domain without the Agent or the Lenders breaching their obligation of confidence
to any Subject Entity, (iii) are previously known by the Agent or the Lenders
from some source other than any Subject Entity, (iv) are hereafter developed by
the Agent or the Lenders without using the Subject Entities' information, (v)
are hereafter obtained by or available to the Agent or the Lenders from a third
party who owes no obligation of confidence to the Subject Entities with respect
to such information or through any other means other than through disclosure by
the Subject Entities, (vi) are disclosed with the Borrower's consent, (vii) must
be disclosed either pursuant to any Governmental Requirement or to Persons
regulating the activities of the Agent or the Lenders, or (viii) as may be
required by law or regulation or order of any Governmental Authority in any
judicial, arbitration or governmental proceeding.  Further, the Agent 


                                    -75-
<PAGE>

or a Lender may in connection with its duties and rights under the Loan 
Documents disclose any such information to any other Lender, any independent 
petroleum engineers or consultants, any independent certified public 
accountants, any legal counsel employed by such Person in connection with 
this Agreement or any other Loan Document, including without limitation, the 
enforcement or exercise of all rights and remedies thereunder, or any 
assignee or participant (including prospective assignees and participants) in 
the Loans; PROVIDED, HOWEVER, that the Agent or the Lenders shall receive a 
confidentiality agreement from the Person to whom such information is 
disclosed such that said Person shall have the same obligation to maintain 
the confidentiality of such information as is imposed upon the Agent or the 
Lenders hereunder.  Notwithstanding anything to the contrary provided herein, 
this obligation of confidence shall cease three (3) years from the date the 
information was furnished, unless the Borrower requests in writing at least 
thirty (30) days prior to the expiration of such three year period, to 
maintain the confidentiality of such information for an additional three year 
period. 

               Section 12.16  EFFECTIVENESS.  This Agreement shall be effective
on the Closing Date (the "EFFECTIVE DATE").

               Section 12.17  EXCULPATION PROVISIONS.  EACH OF THE PARTIES
HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE
OTHER LOAN DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF
THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT
READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF
THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN
REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE
NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS
AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF
THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY
ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING
THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY.  EACH PARTY HERETO
AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF
ANY EXCULPATORY PROVISION OF THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS ON THE
BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE
PROVISION IS NOT "CONSPICUOUS."

the rate from time to time announced by you as your prime commercial rate, with
any change in such interest rate resulting from a change in such prime
commercial rate to be and become effective as of and on the day of the relevant
change in such prime commercial rate, payable on demand. You are hereby
authorized to charge any depository or other account of ours or any of us
maintained with you for the full amount of any drawing paid by you under the
Credit and for payment of any other amount payable by us hereunder not paid to
you on demand. If by charging such account you create an overdraft in one of our
accounts, we shall pay interest to you on such overdrawn amount at the rate
specified in our agreement with you establishing such account or, if no such
rate is specified, at the rate of interest provided for in the first sentence of
this paragraph.

5.     We agree that in the event of any extension of the maturity or time for
presentation of drafts, acceptances or documents, or any other modification of
the terms of the Credit, at the request of any of us, with or without
notification to the others, or in the event of any increase in the amount of the
Credit at our request, this agreement shall be binding upon us with regard to
the credit extended, increased or otherwise modified, to drafts, documents and
property covered thereby, and to any action taken by you or any of your
correspondents, in accordance with such extension, increase or other
modification.

6.     The users of the Credit shall be deemed our agents and we assume all
risks of their acts, omissions, or misrepresentations. Neither you nor your
correspondents shall be responsible for the validity, sufficiency, truthfulness,
or genuineness of any documents even if such documents should in fact prove to
be in any or all respects invalid, insufficient, fraudulent or forged; for
failure of any 


                                       F-2
<PAGE>

draft to bear any reference or adequate reference to the Credit, or failure 
of any person to note the amount of any draft on the reverse of the Credit, 
or to surrender or to take up the Credit as required by the terms of the 
Credit; each of which provisions, if contained in the Credit itself, it is 
agreed may be waived by you, or for errors, omissions, interruptions or 
delays in transmission or delivery of any message, by mail, cable, telegraph, 
wireless, or otherwise, whether or not they be in cipher; nor shall you be 
responsible for any error, neglect or default of any of your correspondents; 
and none of the above shall affect, impair or prevent the vesting of any of 
your rights or powers hereunder. In furtherance and extension and not in 
limitation of the specific provisions hereinbefore set forth, we agree that 
any action taken by you or by any correspondent of yours under or in 
connection with the Credit or the relative drafts, documents or property, if 
taken in good faith, shall be binding on us and shall not put you or your 
correspondent under any resulting liability to us; and we make like agreement 
as to any inaction or omission, unless in breach of good faith.

7.     We agree, to the extent required by the Amended and Restated Credit
Agreement dated as of December 1, 1998 among us, other lenders signatory thereto
and the Bank of Montreal, as Agent (the "Credit Agreement") at any time and from
time to time, on demand, to deliver, convey, transfer or assign to you, as
security for any and all obligations and liabilities of us or any one or more of
us hereunder, and also for any and all other obligations and liabilities,
absolute or contingent due or to become due, which are now or may at any time
hereafter be owing by us or any one or more of us to you, additional security of
a value and character satisfactory to you, or to make such payment as you may
require.

8.     You shall not be deemed to have waived any of your rights hereunder,
unless you or your authorized agent shall have signed such waiver in writing. No
such waiver, unless expressly as stated therein, shall be effective as to any
transaction which occurs subsequent to the date of such waiver, or as to any
continuance of a breach after such waiver.

9.     The word "property", as used in this agreement, includes goods,
merchandise, securities, funds, choses in action, and any and all other forms of
property, whether real, personal or mixed, and any right or interest therein.

10.    Without limiting the foregoing and in addition to the provisions of
paragraph numbered 6 hereof, you are hereby expressly authorized and directed to
honor any request for payment which is made under and in compliance with the
terms of said Credit without regard to, and without any duty on your part to
inquire into, the existence of any disputes or controversies between any of the
undersigned, the beneficiary of the Credit or any other person, firm or
corporation, or the respective rights, duties or liabilities of any of them or
whether any facts or occurrences represented in any of the documents presented
under the Credit are true or correct. Furthermore, we fully understand and agree
that your sole obligation to us shall be limited to honoring requests for
payment made under and in compliance with the terms of the Credit and this
application and your obligation remains so limited even if you may have assisted
us in the preparation of the wording of the Credit or any documents required to
be presented thereunder or you may otherwise be aware of the underlying
transaction giving rise to the Credit and this application. In addition, and
without limiting any of the other provisions hereof, you and your correspondents
may (a) act in reliance upon any oral, telephonic, telegraphic, electronic or
written request or notice believed by you or your relevant correspondent in good
faith to have been authorized by us or any one of us, whether or not given or


                                       F-3
<PAGE>

signed by an authorized person, and (b) receive, accept or pay as complying with
the terms of the Credit any drafts or other document, otherwise in order, that
may be signed by, or issued to, the administrator or executor of, or the trustee
in bankruptcy of, or the receiver for any of the property of, or any other
person or entity acting as the representative of, in the place of or as the
successor in interest to, the party in whose name the Credit provides that any
drafts or other documents should be drawn or issued.

11.    If this agreement is signed by one party, the terms "we," "our," "us,"
shall be read throughout as "I," "my," "me," as the case may be. If this
agreement is signed by two or more parties, it shall constitute the joint and
several agreement of such parties. This agreement shall be deemed to be made
under and shall in all respects be governed by the law of the State of Illinois.
The Credit and, to the extent not inconsistent with the laws of the State of
Illinois, this agreement will be subject to the Uniform Customs and Practice for
Documentary Credits as most recently published by the International Chamber of
Commerce (the "UCP"), except that Article 41 and 43 of the UCP (1993 Revision)
published by the International Chamber of Commerce as Publication No. 500 shall
not apply nor shall any equivalent provision in any future version of the UCP.


                                Very truly yours,
