ITEM 1.  BUSINESS

GENERAL

         Lomak Petroleum, Inc. ("Lomak" or the "Company") is an independent oil
and gas company engaged in the development, exploration and acquisition of oil
and gas properties in the United States. Lomak's core areas of operation are
located in Midcontinent, the Gulf Coast and Appalachia. The Company has grown
through a combination of development, exploration and acquisition activities.
Since January 1, 1991, 62 acquisitions have been consummated at a total cost of
approximately $250 million and approximately $40 million has been expended on
development and exploration activities. As a result, reserves and production
have each grown during this period at a rate in excess of 69% per annum. At
December 31, 1996, proved reserves totaled 384 Bcfe, having a pre-tax present
value at constant prices of $492 million and a reserve life of nearly 14 years.

         At December 31, 1996, Lomak held interests in 6,761 gross (5,187 net)
productive oil and gas wells. The Company currently operates over 6,500 wells
which account for more than 95% of its developed reserves. In addition, the
Company owns and operates approximately 1,900 miles of gas gathering systems in
proximity to its principal gas properties. The Company also provides oil field
services, including brine disposal and various well services primarily for
certain of its own properties. The operations of the Company are considered to
fall within a single industry segment; the exploration for, development and
production of crude oil and natural gas.

         The Company recently acquired oil and gas properties located in West
Texas, South Texas and the Gulf of Mexico (the "Cometra Properties") from
American Cometra, Inc. ("Cometra") for a purchase price of $385 million (the
"Cometra Acquisition"). On a pro forma basis, the Cometra Acquisition increases
the Company's proved reserves at December 31, 1996 by 68% to 644 Bcfe and
increased its Present Value by 98% to $974 million. The Cometra Properties,
located primarily in the Company's core operating areas, include 515 producing
wells, 401 proven development projects and substantial additional development
and exploration potential on approximately 150,000 gross acres (90,000 net
acres). In addition, the Cometra Properties include 265 miles of gas pipelines,
a 25,000 Mcf/d gas processing plant and an above-market gas contract with a
major Texas gas utility covering approximately 30% of the December 1996
production from the Cometra Properties. Forward looking statements included
hereafter will include the effects of the Cometra Acquisition.

         The Company's common stock is listed on the New York Stock Exchange
("NYSE") under the symbol "LOM". During 1996, trading volume averaged 117,600
shares per day. The Company maintains its corporate headquarters at 500
Throckmorton Street, Fort Worth, Texas 76102 and its telephone number is (817)
870-2601.

DESCRIPTION OF THE BUSINESS

  Strategy

          The Company's objective is to continue to increase its asset base,
cash flow and earnings through a balanced strategy of development, exploration
and acquisition activities in core operating areas. In each core area, the
Company establishes separate acquisition, engineering, operating, geological and
other technical expertise. The Company currently has core operating areas in
Midcontinent, the Gulf Coast and Appalachia. Through its strategy, the Company
does not depend solely on any one region or activity to grow its asset base. In
addition, by operating in three core areas, the Company has expanded its
development, exploration and acquisition opportunities.

          Development. The Company's development activities include
recompletions of existing wells, infield drilling and installation of secondary
recovery projects. Development projects are generated within core operating
areas where the Company has significant operational and technical experience. At
December 31, 1996, including the effect of the Cometra Acquisition, over 1,100
proven development projects were in inventory. These projects are geographically
diverse, vary between oil and gas, and are balanced with regard to risk. Between
175 and 200 of these projects are expected to be initiated in 1997 at a total
cost of approximately $45 million. Based on the number of projects currently in
inventory, development expenditures are currently projected to approximate $130
million for the next three years.

          Exploration. Historically, the Company's drilling activities
concentrated on development drilling in its core operating areas. Beginning in
1994, the Company began participating in exploration projects in less developed
or lightly explored formations within its core operating areas. The Company has
an inventory of nearly 300 moderate risk/moderate reward exploitation drilling
opportunities, as well as higher risk/higher reward exploration projects. The
Company's existing inventory of exploration projects and leads varies in risk
and reward based on their depth, location and geology. Lomak has identified 250
exploitation drilling projects principally consisting of step-out drilling from
existing proved or proved undeveloped locations. Current exploration projects
target deeper horizons within existing Company-operated fields, as well as
establishing new fields in exploration trend areas in which Lomak's technical
staff has experience. Lomak's strategy is based upon limiting its risk by
allocating no more than 10% of its cash flow to higher risk exploration
activities and by participating in a variety of projects with differing
characteristics. The Company projects exploitation and exploratory expenditures
to range between $6 million and $7 million in 1997 and currently estimates that
it will spend $25 million on exploitation activities and $20 million on
exploration activities over the next three years.

          Acquisitions. Since January 1, 1991, including the Cometra
Acquisition, 63 acquisitions have been completed for a total consideration of
$635 million. These acquisitions have been made at an average cost of $.74 per
Mcfe. The Company's acquisition strategy has historically been based on: (i)
Locale: focusing in areas containing many small oil and gas operators and where
larger companies are no longer active; (ii) Efficiency: targeting acquisitions
in which operating and cost efficiencies can be obtained; (iii) Reserve
Potential: pursuing properties with the potential for reserve increases through
recompletions and drilling; (iv) Incremental Purchases: seeking acquisitions
where opportunities for purchasing additional interests in the same or
adjoining properties exist; and (v) Complexity: pursuing more complex but less
competitive corporate or partnership acquisitions.

Development Activities

         The Company's development activities include recompletions of existing
wells, infill drilling and installation of secondary recovery projects.
Development projects are generated within core operating areas where the Company
has significant operational and technical expertise. Currently, as described
below, the Company has 1,163 proven development projects in inventory. These
projects are geographically diverse, vary between oil and gas and are balanced
with regard to risk. The following table sets forth information pertaining to
the Company's proven development inventory at December 31, 1996.

</TABLE>


         The Company currently anticipates that it will initiate 175 to 200
development projects in 1997. Assuming that 200 projects are initiated per year,
the Company currently has more than a five year inventory of proven development
projects. Lomak expects to spend approximately $130 million over the next three
years for development.

Exploration Activities

         The Company has an inventory of nearly 300 moderate risk/moderate
reward exploitation drilling opportunities, as well as higher risk/higher reward
exploration projects. Lomak has identified 250 exploitation drilling projects,
principally consisting of step-out drilling from existing proved or proved
undeveloped locations. Current exploration projects target deeper horizons
within existing Company-operated fields, as well as establishing new fields in
exploration trend areas in which Lomak's technical staff has experience. The
Company has not previously, and does not currently, plan to participate in
wildcat exploratory drilling outside its core operating areas.

         Lomak's strategy is based on limiting its risk by allocating no more
than 10% of its cash flow to higher risk exploration activities and by
participating in a variety of projects with differing characteristics. The
Company's existing inventory of exploration projects and leads varies in risk
and reward based on their depth, location and geology. A significant portion of
the existing, as well as future, exploration projects will be enhanced by use of
advanced technology including 3-D seismic and improved completion techniques.

         In each of its core operating areas, the Company's geological and
geophysical staff generate both exploitation and exploration projects with the
assistance of the Company's reservoir engineers, landmen and production
engineers. The Company currently estimates that it will spend $25 million on
exploitation activities and $20 million on exploration activities over the next
three years. Existing exploitation and exploration project inventory is
described below.



                                       4

         Midcontinent. Exploitation projects in the Midcontinent region include
116 infill or step-out drilling locations on leasehold acreage held by currently
producing wells adjacent to the Company's production in the Sterling area of the
Permian Basin, as well as 134 infill or step-out locations on leasehold acreage
held by currently producing wells primarily in the Oakridge and Francis Hill
Fields in the Val Verde Basin. In the Big Lake area of the Permian Basin, the
Company is conducting an analysis to determine the potential for recovery of
additional reserves through increased density drilling. Based on the initial
results of the study, the Company believes there is potential for 200 economic
drill sites on its Big Lake area acreage. Current exploration projects include
deeper drilling to the Ellenburger and Fussleman formations in the Permian and
Val Verde Basins. Several projects targeting the Red Fork, Morrow and Hunton
formations are in various stages of development in the Anadarko Basin. In the
San Juan Basin, the Company's acreage holds exploration potential for production
from the Pictured Cliffs, Gallup and Dakota formations.

         Appalachia. In the Appalachian region, the Company has identified
approximately 100 infill or step-out drilling projects on existing leasehold
acreage. In addition, the Company has identified several hundred additional
potential locations near Company-owned gathering systems on acreage the Company
believes will be available for leasing in the future. The Company believes that
the location of its pipelines will provide it with a competitive advantage in
leasing this acreage, which is currently unleased. These locations target the
blanket Clinton and Medina sandstones. Exploration activity in Appalachia
centers around the drilling of deeper formations from leasehold acreage
generally being held by existing production from shallower production. The
targeted formations are in the Knox Sequence trend, which includes the Rose Run,
Beekmantown and Trempealeau formations. Lomak currently owns leasehold acreage
aggregating over 250,000 net acres in the Knox Sequence trend area. With the
assistance of higher quality 2-D seismic as well as 3-D seismic, Lomak believes
the Knox Sequence trend area could generate substantial reserves over the next
five years.

         Gulf Coast. Exploitation projects in the Gulf Coast region include 34
infill or step-out drilling locations for the Yegua and Frio formations in South
Texas and the Wilcox and Carrizo formations in East Texas. Deeper, higher risk
exploratory projects have been generated in South Texas targeting the Wilcox and
Vicksburg formations. On the offshore properties, 11 exploitation and
exploration projects have been identified to the Lenticulina and Marginulina
sands. There are four exploration projects targeting the Taylor sand of the
Cotton Valley formation in East Texas.

         Recent Significant Acquisitions

         In addition to the Cometra Acquisition, the Company completed a number
of significant acquisitions in 1995 and 1996 as described below. See "Cometra
Acquisition" for a description of the Cometra Acquisition.

         Bannon Interests. In April 1996, the Company acquired interests in
approximately 270 producing wells and 108 proven recompletion and development
drilling opportunities for $37.0 million. After giving effect to a subsequent
sale of certain Rocky Mountain region interests for $6.5 million, the acquired
properties were estimated to contain approximately 71 Bcfe of proved reserves.
Also included were 17,300 net undeveloped acres located in east and south Texas.

         Red Eagle Resources Corporation. Through a series of transactions
effected in late 1994 and early 1995, the Company acquired Red Eagle Resources
Corporation for $29.6 million in cash and $16.9 million of Common Stock. Red
Eagle's assets included interests in approximately 370 producing wells located
primarily in the Okeene Field of Oklahoma's Anadarko Basin. Subsequently, the
Company acquired additional interests in over 100 Red Eagle wells for $3.9
million.

         Eastern Petroleum Company. In January 1996, the Company acquired proved
oil and gas reserves and 40 miles of gas gathering lines in Ohio for $13.7
million. In the second quarter of 1996, the Company initiated a program
extending purchase offers to other interest owners in these properties. Through
September 30, 1996, interests in 61 wells had been purchased for approximately
$100,000.

         Transfuel Interests. In September 1995, the Company acquired proved oil
and gas reserves, 1,100 miles of gas gathering lines and 175,000 undeveloped
acres in Ohio, Pennsylvania and New York from Transfuel, Inc. for $21.0 million.

         Parker & Parsley Interests. In August 1995, the Company purchased
proved oil and gas reserves, 300 miles of gas gathering lines and 16,400
undeveloped acres in Pennsylvania and West Virginia from Parker & Parsley
Petroleum Company for $20.2 million.

         Cometra Acquisition

         GENERAL

         The Company recently acquired the Cometra Properties for a purchase
price of $385 million, consisting of $355 million in cash and 1,410,106 shares
of Common Stock. The Company financed the cash portion of the purchase price
with $221 million of borrowings under the Credit Agreement and the issuance to
Cometra of a $134 million non-interest bearing promissory note due March 31,
1997, which is secured by a bank letter of credit. As a result of the Cometra
Acquisition, the Company has significantly expanded its inventory of both
development and exploration projects, increased its proved reserves at December
31, 1996 by 68% to 644 Bcfe and increased the Company's Present Value at
December 31, 1996 by 98% to $974 million. On March 14, 1997, $186.1 million of
the bank borrowings were repaid through the issuance of 4 million shares of
Common Stock and $125 million of Senior Subordinated Notes.

         COMETRA PROPERTIES

         The Cometra Properties include 150,000 gross acres (90,000 net) located
within the Company's core operating areas in West Texas, South Texas and the
Gulf of Mexico. Netherland, Sewell & Associates, Inc., independent petroleum
consultants, estimated that at December 31, 1996, the Cometra Properties had
proved reserves of 202 Bcf of gas and 9.7 Mmbbls of oil with a Present Value of
$481 million. In December 1996, the Cometra Properties produced at a rate of 66
Mmcfe/d through 515 wells. The Cometra Properties include 265 miles of gas
pipelines and a 25,000 Mcf/d capacity gas processing plant.



                                       6
<PAGE>   7



         The West Texas properties are located in the Val Verde and Permian
Basins and account for 81% of the acquired reserves on a Present Value basis.
The South Texas/Gulf of Mexico properties account for 19% of the acquired
reserves on a Present Value basis. All of the Cometra Properties, except for the
Gulf of Mexico properties, are within the Company's existing core operating
areas. As a result, the Company expects to be able to quickly integrate the
properties and begin exploitation activities. To facilitate the integration, the
Company plans to offer positions to substantially all of Cometra's field and
technical staff associated with these properties.

         On a Present Value basis, 95% and 70%, respectively, of the West Texas
and South Texas/Gulf of Mexico properties are operated by the Company. The
offshore properties are operated by experienced third parties. Although the
Company has no definitive plans to do so at this time, the Company has
previously announced that it may elect to sell all or part of the Gulf of Mexico
properties because they are not located in the Company's core areas.

</TABLE>


         The West Texas properties consist of 450 producing wells on 99,000
gross acres (70,000 net) located principally in the Val Verde and Permian
Basins. The Company operates 95% of the properties on a Present Value basis and
the pipelines and gas processing plant. Existing production ranges in depth from
3,000 to 7,000 feet. The Company has identified 365 proven recompletion and
development drilling projects in this area. In the Val Verde Basin, the Company
benefits from a $3.70 per Mcf gas sales contract covering 20,000 acres currently
producing approximately 20,000 Mcf/d. The contract is with a large gas utility
and expires in June 2000.

         The South Texas/Gulf of Mexico properties consist of 65 producing wells
on 51,000 gross acres (20,000 net). The Company operates 70% of the properties
on a Present Value basis, primarily in South Texas. The Gulf of Mexico
properties include 14 producing wells on seven offshore platforms, all of which
are operated by third parties, including affiliates of National Fuel Gas Co.,
Noble Affiliates, Inc. and British Borneo Petroleum Syndicate plc. Total net
daily production from the South Texas/Gulf of Mexico properties currently is
22,300 Mcfe. Onshore, production comes from depths ranging from 1,000 to 12,000
feet, and has an estimated reserve life in excess of seven years. In the Gulf of
Mexico, production ranges in depth from 8,000 to 14,000 feet, while water depths
vary from 50 to 220 feet. The Company has identified a total of 36 development
projects. Both shallower and deeper horizons hold potential exploration
opportunities, which the Company expects to evaluate further with the assistance
of 3-D seismic technology.

         GAS PLANT AND PIPELINES

         As part of the Cometra Acquisition, the Company has acquired 265 miles
of gas pipelines and a 25,000 Mcf/d capacity gas processing plant in the Permian
Basin. The gas plant, located outside Sterling City, Texas, was constructed in
1995 and is currently processing gas, approximately 50% of which is attributable
to Company operated wells, at the rate of 20,000 Mcf/d. The Company believes
that the plant's capacity could be expanded to 35,000 Mcf/d for an additional
capital expenditure of approximately $4.0 million.

Production

         Production revenue is generated through the sale of oil and gas from
properties held directly and through partnerships and joint ventures. Additional
revenue is received from royalties. While oil and gas production is sold to a
limited number of purchasers, none accounts for more than 10% of oil and gas
revenues, it is believed that the loss of any one of them would not have a
material adverse effect on the business. Proximity to local markets,
availability of competitive fuels and overall supply and demand are factors
affecting the ability to market production. While the Company anticipates an
upward trend in energy prices, factors outside its control such as political
developments in the Middle East, overall energy supply, weather conditions and
economic growth rates have had, and may continue to have, an unpredictable
effect on energy prices.

         The following table sets forth historical revenue and expense
information for the periods indicated (in thousands, except average sales price
and operating cost data).

(a) Oil is converted to Mcfe at a rate of 6 Mcf per barrel.
</TABLE>


         On a Mcfe basis, approximately 77% of 1996 production was natural gas.
Gas production was sold to utilities, brokers or directly to industrial users.
Gas sales are made pursuant to various arrangements ranging from month-to-month
contracts, one year contracts at fixed or variable prices and contracts at fixed
prices for the life of the well. All contracts other than the fixed price
contracts contain provisions for price adjustment, termination and other terms
customary in the industry. A number of the Appalachian gas contracts hold
favorable sales prices when compared to spot market prices. Oil is sold on a
basis such that the purchaser can be changed on 30 days notice. The price
received is generally equal to a posted price set by the major purchasers in the
area. Oil purchasers are selected on the basis of price and service. In 1996,
revenues from oil and gas production amounted to $68.1 million, representing 75%
of revenues. Oil and gas revenues for 1996 increased 82% over 1995.

Field Services

         The field services area is comprised of three components -- well
operations, brine disposal and well servicing. As of December 31, 1996, Lomak
acted as operator of, or provided pumping services for, over 6,500 wells. For
its well operations, the Company receives a monthly fee plus reimbursement of
third party charges. In September 1994 , the Company sold substantially all of
its brine disposal and well servicing assets located in Ohio. During 1996 the
majority of the Company's brine disposal and well servicing activities are
carried out in Oklahoma. In January 1997, the Company completed the sale of its
brine disposal and well servicing activities in Oklahoma.

         In total, field services provided revenues of $14.2 million in 1996,
representing 16% of total revenues. Field service revenues for 1996 increased
41% over the prior year.

    Gas Transportation and Marketing

         The gas transportation and marketing revenues are comprised of fees for
the transportation of production through gathering lines and income from
marketing of oil and gas.

         The Company's natural gas gathering and processing assets are primarily
comprised of (i) its Sterling system obtained through the Cometra Acqusition,
which consists of 265 miles of gas gathering pipelines and a gas processing
plant in the Sterling area of the Permian Basin, and (ii) over 1,900 miles of
gas gathering pipelines in Appalachia. The Sterling plant is a refrigerated
turbo-expander cryogenic gas plant that was placed in service in early 1995. The
plant, designed for approximately 25,000 Mcf/d, is currently operating at 87% of
capacity. The Company estimates that the plant's capacity can be increased to
35,000 Mcf/d for approximately $4.0 million in additional capital expenditures.

         The Appalachian gas gathering systems serve to transport a majority of
the Company's Appalachian gas production as well as third party gas to major
trunklines and directly to industrial end-users. This affords the Company
considerable control and flexibility in marketing its Appalachian production.
Third parties who transport their gas through the systems are charged a
gathering fee ranging from $0.20 to $0.32 per Mcf.

         In order to handle more efficiently the sale of its natural gas, the
Company began to market its own gas production in 1993. Including activities of
the Cometra properties, the Company is currently marketing 173 Mmcf/d for its
own account as well as additional volumes for third party producers. The
Company's gas production is sold primarily to utilities and directly to
industrial users. The Company has managed the impact of potential price declines
by developing a balanced portfolio of fixed price and market sensitive contracts
and commodity hedging. Including production from the Cometra Properties,
approximately 47% of average gas production at December 31, 1996 was sold
subject to fixed price sales contracts. These fixed price contracts are at
prices ranging from $2.15 to $3.70 per Mcf. The fixed price contracts with terms
of less than one year, between one and five years and greater than five years
constitute approximately 31%, 65% and 4%, respectively, of the volume sold under
fixed price contracts.

         From time to time, the Company enters into oil and natural gas price
hedges to reduce its exposure to commodity price fluctuations. At December 31,
1996, approximately 12% on an Mcfe basis of the Company's monthly production for
the period January 1997 to April 1997 was hedged under such arrangements. No
production after this period was hedged. In the future, the Company may hedge a
larger percentage of its production, however, it currently anticipates that such
percentage would not exceed 50%. Although these hedging activities provide the
Company some protection against falling prices, these activities also reduce the
potential benefits to the Company of price increases above the levels of the
hedges.

<PAGE>   10


  Interest and Other

         The Company earns interest on its cash and investment accounts, as well
as on various notes receivable. Other income in 1996 was comprised principally
of gains on sales of marketable equity securities and gains on sales of
non-strategic properties. The Company expects to continue to sell assets which
have no strategic benefit. Interest and other income in 1996 amounted to $3.4
million, representing 4% of total revenues. Revenues from interest and other for
1996 increased 157% from the 1995 level.

COMPETITION

         The Company encounters substantial competition in acquiring properties,
marketing oil and gas, securing personnel and conducting its field services
operations. Many competitors have financial and other resources which
substantially exceed those of the Company. The competitors in acquisitions,
development, exploration and production include the major oil companies in
addition to numerous independents, individual proprietors and others. Therefore,
competitors may be able to pay more for desirable leases and to evaluate, bid
for and purchase a greater number of properties or prospects than the financial
or personnel resources of the Company permit. The ability of the Company to
replace and expand its reserve base in the future will be dependent upon its
ability to select and acquire suitable producing properties and prospects for
future drilling.

         The Company's acquisitions have been partially financed through
issuances of equity and debt securities and internally generated cash flow. The
competition for capital to finance oil and gas acquisitions and drilling is
intense. The ability of the Company to obtain such financing is uncertain and
can be affected by numerous factors beyond its control. The inability of the
Company to raise capital in the future could have an adverse effect on certain
areas of its business.

GOVERNMENTAL REGULATION

         The Company's operations are affected from time to time in varying
degrees by political developments and federal, state and local laws and
regulations. In particular, oil and natural gas production and related
operations are or have been subject to price controls, taxes and other laws and
regulations relating to the oil and gas industry. Failure to comply with such
laws and regulations can result in substantial penalties. The regulatory burden
on the oil and natural gas industry increases the Company's cost of doing
business and affects its profitability. Although the Company believes it is in
substantial compliance with all applicable laws and regulations, because such
laws and regulations are frequently amended or reinterpreted, the Company is
unable to predict the future cost or impact of complying with such laws and
regulations.

ENVIRONMENTAL MATTERS

         The Company's oil and natural gas exploration, development, production
and pipeline gathering operations are subject to stringent federal, state and
local laws governing the discharge of materials into the environment or
otherwise relating to environmental protection. Numerous governmental
departments such as the Environmental Protection Agency ("EPA") issue
regulations to implement and enforce such laws which are often difficult and
costly to comply with and which carry substantial civil and criminal penalties
for failure to comply. These laws and regulations may require the acquisition of
a permit before drilling commences, restrict the types, quantities and
concentrations of various substances that can be released into the environment
in connection with drilling, production and pipeline gathering activities, limit
or prohibit drilling activities on certain lands lying within wilderness,
wetlands, frontier and other protected areas, require some form of remedial
action to prevent pollution from former operations, such as plugging abandoned
wells, and impose substantial liabilities for pollution resulting from the
Company's operations. In addition, these laws, rules and regulations may
restrict the rate of oil and natural gas production below the rate that would
otherwise exist. The regulatory burden on the oil and gas industry increases the
cost of doing business and consequently affects its profitability. Changes in
environmental laws and regulations 



                                       10
<PAGE>   11



occur frequently, and any changes that result in more stringent and costly waste
handling, disposal or clean-up requirements could adversely affect the Company's
operations and financial position, as well as the oil and gas industry in
general. While management believes that the Company is in substantial compliance
with current applicable environmental laws and regulations and the Company has
not experienced any material adverse effect from compliance with these
environmental requirements, there is no assurance that this will continue in the
future.

         The Comprehensive Environmental Response, Compensation and Liability
Act ("CERCLA"), also known as the "Superfund" law, imposes liability, without
regard to fault or the legality of the original conduct, on certain classes of
persons who are considered to be responsible for the release of a "hazardous
substance" into the environment. These persons include the owner or operator of
the disposal site or sites where the release occurred and companies that
disposed or arranged for the disposal of the hazardous substances at the site
where the release occurred. Under CERCLA, such persons may be subject to joint
and several liability for the costs of cleaning up the hazardous substances that
have been released into the environment, for damages to natural resources and
for the costs of certain health studies and it is not uncommon for neighboring
landowners and other third parties to file claims for personal injury and
property damages allegedly caused by the release of hazardous substances or
other pollutants into the environment. Furthermore, although petroleum,
including crude oil and natural gas, is exempt from CERCLA, at least two courts
have ruled that certain wastes associated with the production of crude oil may
be classified as "hazardous substances" under CERCLA and thus such wastes may
become subject to liability and regulation under CERCLA. State initiatives to
further regulate the disposal of oil and natural gas wastes are also pending in
certain states, and these various initiatives could have a similar impact on the
Company.

         Stricter standards in environmental legislation may be imposed in the
oil and gas industry in the future. For instance, legislation has been proposed
in Congress from time to time that would reclassify certain oil and natural gas
exploration and production wastes as "hazardous wastes" and make the
reclassified wastes subject to more stringent handling, disposal and clean-up
restrictions. If such legislation were to be enacted, it could have a
significant impact on the operating costs of the Company, as well as the oil and
gas industry in general. Compliance with environmental requirements generally
could have a material adverse effect upon the capital expenditures, earnings or
competitive position of the Company. Although the Company has not experienced
any material adverse effect from compliance with environmental requirements, no
assurance may be given that this will continue in the future.

         The Federal Water Pollution Control Act ("FWPCA") imposes restrictions
and strict controls regarding the discharge of produced waters and other oil and
gas wastes into navigable waters. Permits must be obtained to discharge
pollutants to state and federal waters. The FWPCA and analogous state laws
provide for civil, criminal and administrative penalties for any unauthorized
discharges of oil and other hazardous substances in reportable quantities and
may impose substantial potential liability for the costs of removal, remediation
and damages. State water discharge regulations and the federal (NPDES) permits
prohibit or are expected to prohibit within the next year the discharge of
produced water and sand, and some other substances related to the oil and gas
industry, to coastal waters. Although the costs to comply with zero discharge
mandated under federal or state law may be significant, the entire industry will
experience similar costs and the Company believes that these costs will not have
a material adverse impact on the Company's financial condition and results of
operations. Some oil and gas exploration and production facilities are required
to obtain permits for their storm water discharges. Costs may be incurred in
connection with treatment of wastewater or developing storm water pollution
prevention plans.

         The Resources Conservation and Recovery Act ("RCRA"), as amended,
generally does not regulate most wastes generated by the exploration and
production of oil and natural gas. RCRA specifically excludes from the
definition of hazardous waste "drilling fluids, produced waters, and other
wastes associated with the exploration, development, or production of crude oil,
natural gas or geothermal energy." However, these wastes may be regulated by the
EPA or state agencies as solid waste. Moreover, ordinary industrial wastes, such
as paint wastes, waste solvents, laboratory wastes and waste compressor 



                                       11
<PAGE>   12



oils, are regulated as hazardous wastes. Although the costs of managing solid
hazardous waste may be significant, the Company does not expect to experience
more burdensome costs than similarly situated companies involved in oil and gas
exploration and production.

         In addition, the U.S. Oil Pollution Act ("OPA") requires owners and
operators of facilities that could be the source of an oil spill into "waters of
the United States" (a term defined to include rivers, creeks, wetlands and
coastal waters) to adopt and implement plans and procedures to prevent any spill
of oil into any waters of the United States. OPA also requires affected facility
owners and operators to demonstrate that they have at least $35 million in
financial resources to pay for the costs of cleaning up an oil spill and
compensating any parties damaged by an oil spill. Substantial civil and criminal
fines and penalties can be imposed for violations of OPA and other environmental
statutes.

EMPLOYEES

         As of December 31, 1996, the Company had approximately 300 full time
employees, of whom 190 were field personnel. None are covered by a collective
bargaining agreement and management believes that its relationship with its
employees is good.

ITEM 2. PROPERTIES

         On December 31, 1996, including the Cometra Properties the Company held
working interests in 7,280 gross (5,586 net) productive oil and gas wells and
royalty interests in 310 additional wells. The properties contained, net to the
Company's interest, estimated proved reserves of 498 Bcf of gas and 24 million
barrels of oil or a total of 644 Bcfe. The Company also held interests in
902,700 gross (628,700 net) undeveloped acres at year end.

        In connection with the evaluation of its reserves, the Company has
engaged the following independent petroleum consultants: Netherland, Sewell &
Associates, Inc. (Cometra Properties), Wright & Company, Inc. (Appalachia),
H.J. Gruy and Associates, Inc. (Midcontinent and Gulf Coast), Huddleston & Co.,
Inc. (Midcontinent) and Clay, Holt & Klammer (Appalachia).  These engineers
have been employed primarily based on geographic expertise as well as their
history in engineering certain of the acquired properties.  At December 31,
1996, approximately 95% of the proved reserves set forth above were evaluated
by independent petroleum consultants, while the remainder were evaluated by the
Company's engineering staff.  All estimates of oil and gas reserves are subject
to significant uncertainty.

         The following table sets forth as of December 31, 1996 the estimated
future net cash flow from and the present value of the proved reserves. Future
net cash flow represents future gross cash flow from the production and sale of
proved reserves, net of production costs (including production taxes, ad valorem
taxes and operating expenses) and future development costs. Such calculations,
which are prepared in accordance with the Statement of Financial Accounting
Standards No. 69 "Disclosures about Oil and Gas Producing Activities" are based
on cost and price factors on December 31, 1996. Average product prices in effect
at December 31, 1996 were $23.58 per barrel of oil and $3.54 per Mcf of gas and
pro forma product prices in effect at December 31, 1996 were $23.23 per barrel
of oil and $3.99 per Mcf of gas. There can be no assurance that the proved
reserves will be developed within the periods indicated or that prices and costs
will remain constant. There are numerous uncertainties inherent in estimating
reserves and related information and different reservoir engineers often arrive
at different estimates for the same properties. No estimates of reserves have
been filed with or included in reports to another federal authority or agency
since December 31, 1996. The following is a table of estimated cash flows at
December 31, 1996, including the Cometra properties.

89% of the wells on a Present Value basis. Production is from 15 different
deltaic Canyon/Cisco sandstones with complex stratigraphic traps at depths
ranging from 2,600 to 6,000 feet. On a Present Value basis, the Oakridge and
Francis Hill Fields contribute 91% of the Val Verde Basin reserves. At December
31, 1996, the Company had an inventory of 76 proven recompletions and 134
development drilling locations.

         Anadarko Basin. The Anadarko Basin properties contain 83 Bcfe of proved
reserves, or 13% of total Present Value. The 431 gross wells (345 net), of which
65% are operated by the Company on a Present Value basis. Net daily production
averages 440 barrels of oil and 14 Mmcf of natural gas. Over 250 operated wells
in the Okeene Field account for 55% of the reserves on a Present Value basis.
The Anadarko Basin wells produce from a variety of sands and carbonates in both
structural and stratigraphic traps in the Hunton, Red Fork and Morrow formations
at depths ranging from 6,000 to 12,000 feet. At December 31, 1996, 117 proven
recompletions and 86 development drilling locations had been identified with

         San Juan Basin. The San Juan Basin properties contain 35 Bcfe of proved
reserves, or 5% of total Present Value. The properties consist of 122 gross
wells (116 net) located in the southeastern portion of the basin, all of which
are Company operated. On an Mcfe basis, 52% of the reserves are oil and natural
gas liquids. Current daily production averages 350 barrels of oil and natural
gas liquids and 2 Mmcf of gas. Producing depths range from 2,000 to 8,000 feet
in the tight blanket sands of the Gallup and Pictured Cliffs zones, as well as
the Dakota formation. These properties have an inventory of 18 proven
recompletions and 29 development drilling locations.

GULF COAST REGION

         The Gulf Coast region consists of onshore properties located in the
East Texas Basin and in South Texas, as well as offshore properties located in
the Gulf of Mexico. Reserves in these areas represent 16% of the Company's total
Present Value. Gulf Coast properties contain 71 Bcfe of proved reserves, of
which approximately 63% are developed. On an Mcfe basis, 65% of the reserves are
natural gas. Current net daily production from these properties averages 1,800
barrels of oil and 21 Mmcf of natural gas. At December 31, 1996, the Gulf Coast
properties were estimated to contain 126 proven development projects.

         South Texas/Gulf of Mexico. The South Texas/Gulf of Mexico properties
contain 54 Bcfe of proved reserves, or 13% of total Present Value. On an Mcfe
basis, gas makes up 79% of the reserves. Current net daily production from the
South Texas/Gulf of Mexico properties totals 1,200 barrels of oil and 21 Mmcf of
gas. Onshore South Texas, these fields range in location from Brooks County in
deep South Texas to Galveston County, near Houston. Significant fields include
Hagist Ranch, Alta Mesa, Riverside, Keeran/Welder and Moses Bayou. These fields
produce from the Wilcox, Frio, Yegua, Vicksburg and Miocene at depths ranging
from 1,000 to 10,000 feet. In total, the onshore fields include 179 gross wells
(153 net), of which 92% are Company operated. The offshore properties in the
Gulf of Mexico include seven platforms offshore Texas and Louisiana in water
depths ranging from 50 to 220 feet. All 15 gross wells (4 net) are operated by
experienced third parties. The Company's working interest in these wells ranges
from 11% to 33%. The offshore properties produce from the Miocene and
Pleistocene age formations, at depths ranging from 8,000 to 14,000 feet. With
multiple producing horizons, untested formations and complex faulting, the South
Texas/Gulf of Mexico properties contain substantial development and exploration
potential, including the continued use of 3-D seismic technology. At December
31, 1996, these properties are estimated to contain 15 proven recompletions and
24 development drilling locations.

         East Texas Basin. The East Texas properties contain 18 Bcfe of proved
reserves accounting for 3% of total Present Value. On an Mcfe basis, 79% of the
reserves are oil. Gross wells total 126 (110 net), of which 74% are Company
operated. Current net daily production averages 620 barrels of oil and 150 Mcf
of gas. Production ranges from the shallow Carrizo section of the Wilcox
formation at a depth of approximately 1,600 feet to the tight Cotton Valley
Taylor blanket sands at approximately 12,000 feet. Approximately 79% of the
Present Value of the East Texas properties is ascribed to 64 operated wells in
the Laura LaVelle Field. At December 31, 1996, 64 proven recompletions and 23
development drilling locations had been identified in the East Texas properties.

APPALACHIAN REGION

         The Appalachian properties contain 188 Bcfe of proved reserves, or 21%
of total Present Value. The reserves are attributable to 5,326 gross wells
(4,417 net wells) located in Pennsylvania, Ohio, West Virginia and New York. The
Company operates 94% of these wells. The reserves, which on an Mcfe basis are
96% natural gas, produce principally from the Medina, Clinton and Rose Run
formations at depths ranging from 2,500 to 7,000 feet. Net daily production
currently totals 400 barrels of oil and 32 Mmcf of gas. After initial flush
production, these properties are characterized by gradual decline rates. Gas
production is transported through 1,900 miles of Company owned gas gathering
systems and is sold primarily to utilities and industrial end-users.

GAS GATHERING AND PROCESSING

         The Company's natural gas gathering and processing assets are primarily
comprised of (i) its Sterling system, which consists of 265 miles of gas
gathering pipelines and a gas processing plant in the Sterling area of the
Permian Basin, and (ii) over 1,900 miles of gas gathering pipelines in
Appalachia. The Sterling plant is a refrigerated turbo-expander cryogenic gas
plant that was placed in service in early 1995. The plant, designed for
approximately 25,000 Mcf/d, is currently operating at 87% of capacity. The
Company estimates that the plant's capacity can be increased to 35,000 Mcf/d at
a cost of approximately $4.0 million.

         The Appalachian gas gathering systems serve to transport a majority of
the Company's Appalachian gas production as well as third party gas to major
trunklines and directly to industrial end-users. This affords the Company
considerable control and flexibility in marketing its Appalachian production.
Third parties who transport their gas through the systems are charged a
gathering fee ranging from $0.20 to $0.32 per Mcf.

OIL AND GAS MARKETING

         In order to more efficiently handle the sale of its natural gas, the
Company began to market its own production in 1993. On a pro forma basis at
year end, the Company was marketing 173 Mmcf/d for its own account as well as
additional volumes for third party producers. The Company's gas production is
sold primarily to utilities and directly to industrial users.

         The Company has managed the impact of potential price declines by
developing a balanced portfolio of fixed price and market sensitive contracts
and commodity hedging. On a pro forma basis, approximately 47% of average gas
production at December 31, 1996 was sold subject to fixed price sales contracts.
These fixed price contracts are at prices ranging from $2.15 to $3.70 per Mcf.
The fixed price contracts with terms of less than one year, between one and five
years and greater than five years constitute approximately 31%, 65% and 4%,
respectively, of the volume sold under fixed price contracts.

         From time to time, the Company enters into oil and natural gas price
hedges to reduce its exposure to commodity price fluctuations. At December 31,
1996, approximately 12% on an Mcfe basis of the Company's monthly production for
the period January 1997 to April 1997 was hedged under such arrangements. No
production after this period was hedged. In the future, the Company may hedge a
larger percentage of its production.



                                       17
<PAGE>   18



         Approximately 30% of the Company's pro forma December 1996 gas
production on an Mcfe basis was attributable to Appalachia. Gas production in
Appalachia has historically received a higher price, due to its proximity to the
northeastern gas markets.

         The Company's oil production is sold at the well head at posted field
prices tied to the spot oil markets. Oil purchasers are selected on the basis of
price and service.

         As part of the Cometra Acquisition, the Company acquired an above
market gas contract with a major Texas Gas Utility Company, which expires 
June 30, 2000. The contract represents 17% of the Company's pro forma December 
1996 production on an Mcfe basis. The price paid pursuant to the contract 
converts to a price of $3.70 per Mcf ($3.30 per Mmbtu) at December 31, 1996. 
The gas contract provides for price escalation of $0.05 per Mcf on July 1 of 
each year. No other purchaser of the  Company's oil or gas during 1996 exceeded 
10% of the Company's total revenues.

REAL PROPERTY

          The Company owns a 24,000 square foot facility located on
approximately seven acres near Hartville, Ohio. The facility houses certain
operating and administrative personnel. The Company leases approximately 33,000
square feet in Fort Worth and Oklahoma City under standard office lease
arrangements that expire at various times through March 2004. All facilities are
adequate to meet the Company's existing needs and can be expanded with minimal
expense.

          The Company owns various rolling stock and other equipment which is
used in its field operations. Such equipment is believed to be in good repair
and, while such equipment is important to its operations, it can be readily
replaced as necessary.

ITEM 3.  LEGAL PROCEEDINGS

         The Company is involved in various legal actions and claims arising in
the ordinary course of business. In the opinion of management, such litigation
and claims will be resolved without a material adverse effect on the Company's
financial position.

         The Company recently received notice from two parties, each of whom
claims that it is entitled to fees from the Company based upon a Yemen oil
concession that they claim Red Eagle Resources Corporation received in August
1992, which was prior to the acquisition of Red Eagle by the Company. Based upon
the Company's examination of the available documentation relevant to such
claims, the Company believes that the claims are without merit because the oil 
concession was never obtained. The Company has requested further documentation
from the two parties with respect to their claims but no such documentation has
yet been provided. The claims are for approximately $4.0 million in the
aggregate (including the value of approximately 70,000 shares of Common Stock
that would be required to be issued if the oil concession had been obtained).
To date, no proceedings have been commenced with respect to either of these
claims.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         None.

</TABLE>


DIVIDENDS

         Dividends on the Common Stock were initiated in late 1995 and have
been paid in each quarter since that time. The $2.03 Convertible Preferred 
Stock is entitled to receive cumulative quarterly dividends at the annual rate 
of $2.03 per share. If there is any arrearage in dividends on preferred stock,
the Company may not pay dividends on the Common Stock. The Company has never
been in arrears in the payment of preferred dividends.

         The payment of dividends is subject to declaration by the Board of
Directors and may depend on earnings, capital expenditures and market factors
existing from time to time. The Amended Credit Facility and the Indenture for
the 6% Convertible Subordinated Debenture Due 2007 and 8.75% Senior Subordinated
Notes due 2007 contain restrictions on the Company's ability to pay dividends on
capital stock. Under the most restrictive of these provisions, the Company could
have paid $5 million of dividends as of December 31, 1996.

HOLDERS OF RECORD

         At March 17, 1997, the number of holders of record of the Common Stock
and $2.03 Convertible Preferred Stock were approximately 4,300 and 2,
respectively.

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

FACTORS EFFECTING FINANCIAL CONDITION AND LIQUIDITY

         LIQUIDITY AND CAPITAL RESOURCES

General

         Working capital at December 31, 1996 was $12.9 million, representing an
$8.3 million increase over the corresponding amount at December 31, 1995. At
December 31, 1996, the Company had $8.6 million in cash and total assets of
$282.5 million. During 1996, long-term debt rose from $83.0 million to $116.8
million.

         At December 31, 1996, capitalization totaled approximately $234
million, of which approximately 50% was represented by stockholders' equity and
50% by long-term debt. Approximately $61.4 million of the long-term debt at that
date was comprised of borrowings under the Credit Agreement, $55 million being
comprised of 6% Convertible Subordinated Debentures and the remaining $500,000
comprised of other indebtedness. The Credit Agreement currently provides for
quarterly payments of interest with principal due in February 2002.

         In December 1996, the Company sold $55 million of 6% Convertible
Subordinated Debentures in a private placement. Net proceeds to the Company of
approximately $53 million were used, together with internally generated funds,
to reduce the amount outstanding under the Credit Agreement to $61.4 million at
December 31, 1996. The 6% Convertible Subordinated Debentures are redeemable by
the Company after February 1, 2000 and are convertible at the option of the
holder into Common Stock at any time prior to maturity or redemption at a
conversion price of $19.25 per share, subject to adjustment in certain
circumstances.

Cash Flow

         The Company has three principal operating sources of cash: (i) sales of
oil and gas; (ii) revenues from field services and (iii) revenues from gas
transportation and marketing. The Company's cash flow is highly dependent upon
oil and gas prices. Decreases in the market price of oil or gas could result in
reductions of both cash flow and the borrowing base under the Credit Agreement
which would result in decreased funds available, including funds intended for
planned capital expenditures.

         The Company's net cash provided by operations for the years ended
December 31, 1994, 1995 and 1996 was $11.2 million, $16.6 million and $38.4
million, respectively. The increases in the Company's cash flow from operations
can be attributed to its growth primarily through acquisitions and development.

         The Company's net cash used in investing for the years ended December
31, 1994, 1995 and 1996 was $29.5 million, $76.1 million and $69.7 million,
respectively. Investing activities for these periods are comprised primarily of
additions to oil and gas properties through acquisitions and development and, to
a lesser extent, exploitation and additions of field service assets. These uses
of cash have historically been partially offset through the Company's policy of
divesting those properties that it deems to be marginal or outside of its core 
areas of operation. The Company's acquisition and development activities have 
been financed through a combination of operating cash flow, bank borrowings and
capital raised through equity and debt offerings.



                                       21

\

         The Company's net cash provided by financing for the years ended
December 31, 1994, 1995 and 1996 was $21.2 million, $57.7 million and $36.8
million, respectively. Sources of financing used by the Company have been
primarily borrowings under its Credit Agreement and capital raised through
equity and debt offerings.

Capital Requirements

         In 1996, $12.5 million and $2.0 million of expenses were incurred for
development activities and exploration activities, respectively. Although these
expenditures are principally discretionary, the Company is currently projecting
that it will spend approximately $160 million on development, exploitation and
exploration activities, which includes approximately $45 million on exploitation
and exploration expenditures, for the three years ending 1999. For the next
three years, development and exploration expenditures are currently expected to
consume roughly 50% of internally generated cash flows. The remaining funds will
be available for acquisitions and other capital expenditures. See
"Business--Development Activities" and "--Exploration Activities."

Credit Agreement

         In connection with the financing of the Cometra Acquisition, the
Company and its subsidiaries expanded the existing bank credit facility. The
Credit Agreement permits the Company to obtain revolving credit loans and to
issue letters of credit for the account of the Company from time to time in an
aggregate amount not to exceed $400 million (of which not more than $150 million
may be represented by letters of credit). The Borrowing Base, which was
initially $400 million, was reduced to $300 million upon the consummation of the
Offerings. The Borrowing Base is subject to semi-annual determination and
certain other redeterminations based upon a variety of factors, including the
discounted present value of estimated future net cash flow from oil and gas
production. The Company is required to make a mandatory prepayment of all
amounts outstanding under the Credit Agreement in excess of $300 million. At the
Company's option, loans may be prepaid, and revolving credit commitments may be
reduced, in whole or in part at any time in certain minimum amounts. Security
obligations in place with the Credit Agreement were released upon the
consummation of the Offerings on March 14, 1997.

         At the Company's option, the applicable interest rate per annum is
the LIBOR plus a margin ranging from 0.625% to 1.125%. As an alternative, the
Company can elect an Alternate Base Rate (as defined) plus a margin ranging
from 0% to 0.25%. The Alternate Base Rate is the higher of (a) the
administrative agent bank's prime rate and (b) the federal funds effective rate
plus 0.5%.

         On March 17, 1997, approximately $204 million was outstanding
(including $134 million of then outstanding letters of credit to secure the
promissory note issued to Cometra as part of the purchase price in the Cometra
Acquisition) under the Credit Agreement. The promissory note to Cometra matures
on March 31, 1997.

Common Stock and Notes Offering

         On March 14, 1997, the Company completed a 4,060,000 million share 
Common stock offering (the "Common Offering") and a $125 million aggregate
principal amount  of its 8.75% Senior Subordinated Notes due 2007 (the "Notes
Offering")(collectively the "Offerings"). The Notes are unconditionally
guaranteed on an unsecured, senior subordinated basis, by each of the Company's
Restricted Subsidiaries (as defined in the Indenture for the Notes), provided
that such guarantees will terminate under certain circumstances. The Indenture
for the Notes contains certain covenants, including, but not limited to,
covenants with respect to the following matters: (i) limitation on restricted
payments; (ii) limitation on the incurrence of indebtedness and issuance of
Disqualified Stock (as defined in the Indenture for the Notes); (iii)
limitation on liens; (iv) limitation on disposition of proceeds of asset sales;
(v) limitation on transactions with affiliates; (vi) limitation on dividends
and other payment restrictions affecting restricted subsidiaries; (vii)
restrictions on mergers, consolidations and transfers of assets; and (viii)
limitation on "layering" indebtedness.

<PAGE>   23


Hedging Activities

         Periodically, the Company enters into futures, option and swap
contracts to reduce the effects of fluctuations in crude oil and natural gas
prices. At December 31, 1996, the Company had open contracts for oil and gas
price swaps of 300,000 barrels of oil at average prices ranging from $22.10 to
$22.76 per barrel of oil and 155,000 MmBtu of gas at $2.04 per MmBtu. While
these transactions have no carrying value, the Company's mark-to-market exposure
under these contracts at December 31, 1996 was a net loss of $1.1 million. As
of February 28, 1997, the Company had open hedge contracts covering 140,000
barrels of oil with mark-to-market exposure of a $290,000 net gain. These
contracts expire monthly through April 1997. The gains or losses on the
Company's hedging transactions is determined as the difference between the
contract price and a reference price, generally closing prices on the NYMEX. The
resulting transaction gains and losses are determined monthly and are included
in the period the hedged production or inventory is sold. Net gains or losses
relating to these derivatives for the years ended December 31, 1994, 1995 and
1996 approximated $0, $217,000 and $(724,000), respectively.

         INFLATION AND CHANGES IN PRICES

         The Company's revenues and the value of its oil and gas properties have
been and will be affected by changes in oil and gas prices. The Company's
ability to maintain current borrowing capacity and to obtain additional capital
on attractive terms is also substantially dependent on oil and gas prices. Oil
and gas prices are subject to significant seasonal and other fluctuations that
are beyond the Company's ability to control or predict. During 1996, the Company
received an average of $19.12 per barrel of oil and $2.24 per Mcf of gas.
Although certain of the Company's costs and expenses are affected by the level
of inflation, inflation did not have a significant effect in 1996. Should
conditions in the industry improve, inflationary cost pressures may resume.

RESULTS OF OPERATIONS

Comparison of 1996 to 1995

         The Company reported net income for the year ended December 31, 1996 of
$12.6 million, a 187% increase over 1995. The increase is the result of (i)
higher production volumes, over 60% of which is attributable to acquisitions and
the remainder is attributable to development activities; (ii) increased prices
received from the sale of oil and gas products and (iii) gains from asset sales.
During the year, oil and gas production volumes increased 54% to 27.6 Bcfe, an
average of 76 Mmcfe/d. The increased revenues recognized from production volumes
were aided by an 18% increase in the average price received per Mcfe of
production to $2.46. The average oil price increased 15% to $19.12 per barrel
while average gas prices increased 25% to $2.24 per Mcf. As a result of the
Company's larger base of producing properties and production, oil and gas
production expenses increased 64% to $24.5 million in 1996 versus $14.9 million
in 1995. The average operating cost per Mcfe produced increased 6% from $0.83 in
1995 to $0.88 in 1996 due to unsuccessful recompletion costs and increases in
personnel costs.

         Gas transportation and marketing revenues increased 70% to $5.6 million
versus $3.3 million in 1995 principally due to production growth. Gas
transportation and marketing expenses increased 97% to $1.7 million versus $0.8
million in 1995. The increase in expenses was due to production growth, as well
as the increase in gas transportation and marketing expense and higher
administrative costs associated with the growth in gas marketing.

         Field services revenues increased 41% in 1996 to $14.2 million. The
higher revenues were due primarily to a larger base of operated properties.
Field services expenses increased 61% in 1996 to $10.4 million versus $6.5
million. The increase is attributed to the cost of operating a larger base of
properties and lower overall margins on Oklahoma well servicing. In December
1996, the Company sold its brine disposal and well servicing activities in
Oklahoma for $2.7 million and recorded a gain of approximately $1.2 million,
which is included in interest and other income.

         Exploration expense increased 185% to $1.5 million due to the Company's
increased involvement in seismic and exploratory drilling. The Company
participated in 11 exploratory wells in 1996 versus 7 exploratory wells in 1995.

         General and administrative expenses increased 45% from $2.7 million in
1995 to $3.9 million in 1996. As a percentage of revenues, general and
administrative expenses were 4% in 1996 as compared to 5% in 1995. This
decreasing trend reflects the spreading of administrative costs over a growing
asset base.

         Interest and other income rose 157% to $3.4 million primarily due to
$1.4 million on gains from sale of marketable securities (which were not related
to hedging activities), and $1.2 million from the gain on the sale of the
Oklahoma well servicing assets. Interest expense increased 34% to $7.5 million
as compared to $5.6 million in 1995. This was primarily as a result of the
higher average outstanding debt balance during the year due to the financing of
capital expenditures. The average outstanding balances on the Credit Agreement
were $73.3 million and $107.2 million for 1995 and 1996, respectively. The
weighted average interest rate on these borrowings were 7.3% and 6.7% for the
years ended December 31, 1995 and 1996, respectively.

         Depletion, depreciation and amortization increased 50% compared to 1995
as a result of increased production volumes during the year. The Company-wide
depletion rate was $0.73 per Mcfe in 1995 and 1996.

Comparison of 1995 to 1994

         The Company reported net income for the year ended December 31, 1995 of
$4.4 million, a 68% increase over 1994. This increase is the result of higher
production volumes attributable to acquisition and development activities.



                                       24
<PAGE>   25



         During the year, oil and gas production volumes increased 66% to 17.9
Bcfe, an average of 49.2 Mmcfe/d. The increased revenues recognized from
production volumes were partially offset by an 8% decrease in the average price
received per Mcfe of production to $2.08. The average oil price increased 9% to
$16.57 per barrel while average gas prices dropped 15% to $1.79 per Mcf. As a
result of the Company's larger base of producing properties and production, oil
and gas production expenses increased 49% to $14.9 million in 1995 versus $10.0
million in 1994. However, the average operating cost per Mcfe produced decreased
11% from $0.93 in 1994 to $0.83 in 1995.

         Gas transportation and marketing revenues increased 50% to $3.3 million
versus $2.2 million in 1994. Coupled with this increase in gas transportation
and marketing revenues was a 73% increase in associated expenses for the year.
These increases were due primarily to the acquisition of several pipeline
systems, as well as the expansion of the gas marketing efforts.

         Field services revenues increased 32% in 1995 to $10.1 million, despite
the September 1994 sale of virtually all well servicing and brine disposal
assets in Ohio. The decrease in activities due to this sale was more than offset
by an increase in well servicing and brine disposal activities in Oklahoma and
well operations on acquired properties. Field services expenses increased 12% in
1995 to $6.5 million versus $5.8 million. The increase is attributed to the
Oklahoma well servicing and the cost of operating a larger base of properties.
The increase in well operating costs was offset to a great extent by the
disposal in September 1994 of the Company's lower margin well servicing and
brine hauling and disposal businesses.

         Exploration expense increased 43% to $0.5 million due to the Company's
increased involvement in exploration projects. These costs include delay
rentals, seismic and exploratory drilling activities.

         General and administrative expenses increased 10% from $2.5 million in
1994 to $2.7 million in 1995. As a percentage of revenues, general and
administrative expenses were 5% in 1995 as compared to 7% in 1994. This
improvement reflects the spreading of administrative costs over a growing asset
base.

         Interest and other income rose 180% primarily due to higher sales of
non-strategic properties. Interest expense increased 99% to $5.6 million as
compared to $2.8 million in 1994. This was primarily as a result of the higher
average outstanding debt balance during the year due to the financing of capital
expenditures. The average outstanding balances on the Credit Agreement were
$42.0 million and $73.3 million for 1994 and 1995, respectively. The weighted
average interest rate on these borrowings was 6.3% and 7.3% for the years ended
December 31, 1994 and 1995, respectively.

         Depletion, depreciation and amortization increased 47% compared to 1994
as a result of increased production volumes during the year. The increased
depletion of oil and gas properties was partially offset by the reduction of
depreciation of field services assets due to the 1994 sale of field service
assets. The Company-wide depletion rate for 1995 was $0.73 per Mcfe versus $0.74
per Mcfe in 1994 due to the addition of properties at lower than historical Mcfe
costs.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

THE BOARD OF DIRECTORS AND STOCKHOLDERS
         LOMAK PETROLEUM, INC.

         We have audited the accompanying consolidated balance sheets of Lomak
Petroleum, Inc. (a Delaware corporation) as of December 31, 1995 and 1996, and
the related consolidated statements of income, stockholders' equity and cash
flows for the three years in the period ended December 31, 1996. These 
financial statements are the responsibility of the Company'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, the financial statements referred to above present
fairly, in all material respects, the financial position of Lomak Petroleum,
Inc. as of December 31, 1995 and 1996, and the results of its operations and its
cash flows for the three years in the period ended December 31, 1996, in 
conformity with generally accepted accounting principles.

                            Lomak Petroleum, Inc.
                  Notes to Consolidated Financial Statements


(1)      ORGANIZATION AND NATURE OF BUSINESS

         Lomak Petroleum, Inc. ("Lomak" or the "Company") is an independent oil
company engaged in development, exploration and acquisition primarily in three
core areas: Midcontinent, the Gulf Coast and Appalachia. Historically, the
Company has increased its reserves and production through acquisitions,
development and exploration of its properties. Over the past six years, 62
acquisitions have been consummated at a total cost of $249 million and
approximately $39 million has been expended on development and exploration
activities. As a result, proved reserves and production have each grown during
this period at compound rates of 90% and 70% per annum, respectively. At
December 31, 1996, proved reserves totaled 384 Bcfe, having a pre-tax present
value at constant prices on that date of $492 million and a reserve life of
approximately 14 years.

         Effective January 1997, the Company acquired oil and gas properties
from American Cometra, Inc. for a purchase price of $385 million, subject to
adjustment. This transaction is more fully described in Note (15) Cometra
Acquisition.

         Lomak's objective is to maximize shareholder value through growth in
its reserves, production, cashflow and earnings through a balanced program of
development drilling and acquisitions, as well as, to a growing extent,
its exploration effort. In order to effectively pursue its operating strategy,
the Company has concentrated its activities in selected geographic areas. In
each core area, the Company has established separate acquisition, engineering,
geological, operating and other technical expertise. The Company believes that
this geographic focus provides it with a competitive advantage in sourcing and
evaluating new business opportunities within these areas, as well as providing
economies of scale in developing and operating its properties.

(2)      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

         The accompanying financial statements include the accounts of the
Company, all majority owned subsidiaries and its pro rata share of the assets,
liabilities, income and expenses of certain oil and gas partnerships and joint
ventures. Highly liquid temporary investments with an initial maturity of ninety
days or less are considered cash equivalents.

OIL AND GAS PROPERTIES

         The Company follows the successful efforts method of accounting for oil
and gas properties. Exploratory costs which result in the discovery of reserves
and the cost of development wells are capitalized. Geological and geophysical
costs, delay rentals and costs to drill unsuccessful exploratory wells are
expensed. Depletion is provided on the unit-of-production method. Oil is
converted to Mcfe at the rate of six Mcf per barrel. The depletion rates per
Mcfe were $.74, $.73 and $.73 in 1994, 1995 and 1996, respectively.
Approximately $4.3 million, $12.2 million and $22.8 million of oil and gas
properties were not subject to amortization as of December 31, 1994, 1995 and
1996, respectively. These costs are assessed periodically to determine whether
their value has been impaired, and if impairment is indicated, the excess costs
are charged to expense.

         Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards No. 121 "Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed Of," which establishes accounting
standards for the impairment of long-lived assets, certain identifiable
intangibles and goodwill. SFAS No. 121 requires a review for impairment whenever
circumstances indicate that the carrying amount of an asset may not be
recoverable. In performing the review for recoverability, the Company would
estimate future cash flows ( undiscounted and without interest charges) expected
to result from the use of an asset and its eventual disposition. Impairment is
recognized only if the carrying amount of an asset is greater than its expected
future cash flows. The amount of the 


                                       38
<PAGE>   39




impairment is based on the estimated fair value of the asset. The adoption of 
SFAS No. 121 has no impact on the Company.

GAS IMBALANCES

         The Company uses the sales method to account for gas imbalances. Under
the sales method, revenue is recognized based on cash received rather than the
proportionate share of gas produced. Gas imbalances at year end 1995 and 1996
were not material.

GAS TRANSPORTATION AND FIELD SERVICE ASSETS

         The Company owns and operates approximately 1,900 miles of gas
gathering lines in proximity to its principal gas properties. Depreciation is
calculated on the straight-line method based on estimated useful lives ranging
from four to fifteen years.

         The Company receives fees for providing field related services. These
fees are recognized as earned. Depreciation is calculated on the straight-line
method based on estimated useful lives ranging from one to six years, except for
buildings which are being depreciated over ten to fifteen year periods.

         During 1996 the majority of the Company's brine disposal and well
servicing activities were based in Oklahoma. In December 1996, the Company sold
its brine disposal and well servicing activities in Oklahoma for $2.7 million
and recorded a gain on sale of approximately $1.2 million which is included in
interest and other income. In 1994, the Company sold substantially all of its
brine disposal and well servicing assets located in Appalachia for approximately
$1.8 million.

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.

NATURE OF BUSINESS

         The Company operates in an environment with many financial and
operating risks, including, but not limited to, the ability to acquire
additional economically recoverable oil and gas reserves, the inherent risks of
the search for, development of and production of oil and gas, the ability to
sell oil and gas at prices which will provide attractive rates of return, and
the highly competitive nature of the industry and worldwide economic conditions.
The Company's ability to expand its reserve base and diversify its operations is
also dependent upon obtaining the necessary capital through operating cash flow,
borrowings or the issuance of additional equity.

MARKETABLE SECURITIES

         In 1995, the Company adopted Statement of Financial Accounting 
Standards No. 115, "Accounting for Certain Investments in Debt and Equity
Securities." Under Statement No. 115, debt and marketable equity securities are
required to be classified in one of three categories: trading,
available-for-sale, or held to maturity. The Company's equity securities
qualify under the provisions of Statement No. 115 as available-for-sale. Such
securities are recorded at fair value, and unrealized holding gains and losses,
net of the related tax effect, are reflected as a separate component of
stockholders' equity. A decline in the market value of an available-for-sale
security below cost that is deemed other than temporary is charged to earnings
and results in the establishment of a new cost basis for the security. Realized
gains and losses are determined on the specific identification method and are
reflected in income.



                                       39

DEBT ISSUANCE COSTS

         Expenses associated with the issuance of the 6% Convertible
Subordinated Debentures Due 2007 are included in Other Assets on the
accompanying balance sheet and are being amortized on the interest method over
the term of the debentures.

EARNINGS PER COMMON SHARE

         Net income per share is computed by subtracting preferred dividends
from net income and dividing by the weighted average number of common and common
equivalent shares outstanding. The calculation of fully diluted earnings per
share assumes conversion of convertible securities when the result would be
dilutive. Outstanding options and warrants are included in the computation of
net income per common share when their effect is dilutive.

RECLASSIFICATIONS

         Certain reclassifications have been made to prior period presentation
to conform with current period classifications.

(3)      ACQUISITION AND DEVELOPMENT

         All of the Company's acquisitions have been accounted for as purchases.
The purchase prices were allocated to the assets acquired based on the fair
value of such assets and liabilities at the respective acquisition dates. The
acquisitions were funded by working capital, advances under a revolving credit
facility and the issuance of equity.

         During 1996, the Company acquired oil and gas properties, equipment and
acreage from Bannon Energy, Incorporated for approximately $37.0 million and
acquired Eastern Petroleum Company for approximately $13.7 million. The Bannon
interests included 270 producing properties located in Texas, Oklahoma, New
Mexico and Wyoming. Eastern Petroleum Company owned interests in oil and gas
properties, equipment and acreage in Ohio. In addition, the Company acquired
other interests totaling $12.9 million during the year.

         In 1995, the Company acquired oil gas properties, equipment and acreage
from Transfuel, Inc. for $21 million, which included cash and approximately
$800,000 of Common Stock, and from Parker & Parsley Petroleum Company for $20.2
million. The Transfuel interests included developed and undeveloped properties
in Ohio, Pennsylvania and New York. The Parker & Parsley interests included
developed and undeveloped properties in Pennsylvania and Ohio.

         In 1994, the Company acquired Red Eagle Resources Corporation for $46.5
million. Included in this amount were 2.8 million shares of Common Stock valued
at approximately $16.9 million issued to the acquired company's shareholders. 
Red Eagle's assets included 370 producing wells, equipment and acreage located
primarily in the Okeene Field of Oklahoma's Anadarko Basin. In addition, the
Company purchased Grand Banks Energy Company for $3.7 million and Gillring Oil
Company for $11.5 million. Grand Bank's assets included interests in 182
producing properties located in west Texas and Gillring's assets included $5.2
million of working capital and interests in 106 producing properties located in
south Texas.

</TABLE>

         The Company maintains a $250 million revolving bank credit facility.
The facility provides for a borrowing base which is subject to semi-annual
redeterminations. At December 31, 1996, the borrowing base on the credit
facility was $150 million. The facility bears interest at prime rate of LIBOR
plus 0.75% to 1.25% depending upon the percentage of the borrowing base drawn.
Interest is payable quarterly and the loan is payable in sixteen quarterly
installments beginning February 1, 1999. A commitment fee of 3/8% of the undrawn
balance is payable quarterly. It is the Company's policy to extend the term
period of the credit facility annually.



                                       41
<PAGE>   42



         As described in Note (15), the revolving bank credit facility was
amended and expanded in connection with the financing of the Cometra Acquisition
(the "Amended Credit Facility"). The Amended Credit Facility is secured by first
priority security interests in (i) existing mortgaged oil and gas properties of
the Company, including the Cometra Properties, (ii) all accounts receivable,
inventory and intangibles of the Company and the subsidiaries guaranteeing the
Amended Credit Facility, and (iii) all of the capital stock of the Company's
direct and indirect subsidiaries. Substantially all of the assets of the Company
will be pledged as collateral if, on May 15, 1997, the Borrowing Base and
amounts outstanding under the Amended Credit Facility have not been reduced to
$325 million. Such security interests will be released upon the (i) reduction of
the amounts outstanding under the Amended Credit Facility to $325 million (or
the then determined Borrowing Base) and (ii) issuance of $65 million of Common
Stock and/or the sale of Company assets in excess of the Borrowing Base value
attributable to such assets as agreed by the lenders.

         The 6% Convertible Subordinated Debentures Due 2007 (the "Debentures")
are convertible at the option of the holder at any time prior to maturity into
shares of the Company's Common Stock, at a conversion price of $19.25 per share,
subject to adjustment in certain events. Interest is payable semi-annually. The
Debentures will mature in 2007 and are not redeemable prior to February 1, 2000.
The Debentures are unsecured general obligations of the Company subordinated to
all senior indebtedness, as defined.

         The debt agreements contain various covenants relating to net worth,
working capital maintenance and financial ratio requirements. The Company is in
compliance with these various covenants as of December 31,1996. Interest paid
during the years ended December 31, 1994, 1995 and 1996 totaled $2.8 million,
$4.9 million and $7.5 million, respectively.

         Maturities of indebtedness as of December 31, 1996 were as follows (in
thousands):

(5)      FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES:

         The Company's financial instruments include cash and equivalents,
accounts receivable, accounts payable, debt obligations, commodity and interest
rate futures, options, and swaps. The book value of cash and equivalents,
accounts receivable and payable and short term debt are considered to be
representative of fair value because of the short maturity of these instruments.
The Company believes that the carrying value of its borrowings under its bank
credit facility approximates their fair value as they bear interest at rates
indexed to LIBOR. The Company's accounts receivable are concentrated in the oil
and gas industry. The Company does not view such a concentration as an unusual
credit risk. The Company had recorded an allowance for doubtful accounts of
$306,000 and $450,000 at December 31, 1995 and 1996, respectively.

         A portion of the Company's crude oil and natural gas sales are
periodically hedged against price risks through the use of futures, option or
swap contracts. The gains and losses on these instruments are included in the
valuation of the production being hedged in the contract month and are included
as an adjustment to oil and gas revenue. The Company also manages interest rate
risk on its credit facility through the use of interest rate swap agreements.
Gains and losses on swap agreements are included as an adjustment to interest
expense.

         At December 31, 1996, the Company had open contracts for oil and gas
price swaps of 300,000 barrels and 155,000 Mcfs. The swap contracts are designed
to set average prices ranging from $22.10 to $22.76 per barrel and $2.04 per
Mcf. While these transactions have no carrying value, their fair value,
represented by the estimated amount that would be required to terminate the
contracts, was a net cost of approximately $1,051,000 at December 31, 1996.
These contracts expire monthly through April 1997. The gains or losses on the
Company's hedging transactions is determined as the difference between the
contract price and the reference price, generally closing prices on the New York
Mercantile Exchange. The resulting transaction gains and losses are determined
monthly and are included in net income in the period the hedged production or
inventory is sold. Net gains or (losses) relating to these derivatives for the
years ended December 31, 1994, 1995 and 1996 approximated $-0-, $217,000 and
$(724,000) respectively.

         Interest rate swap agreements, which are used by the Company in the
management of interest rate exposure, is accounted for on the accrual basis.
Income and expense resulting from these agreements are recorded in the same
category as expense arising from the related liability. Amounts to be paid or
received under interest rate swap agreements are recognized as an adjustment to
expense in the periods in which they accrue. At December 31, 1996, the Company
had $60 million of borrowings subject to three interest rate swap agreements at
rates of 5.25%, 5.49% and 5.64% through July 1997, October 1997 and October
1998, respectively. The interest rate swaps may be extended at the
counterparties' option for two years. The agreements require that the Company
pay the counterparty interest at the above fixed swap rates and requires the
counterparty to pay the Company interest at the 30-day LIBOR rate. The closing
30-day LIBOR rate on December 31, 1996 was 5.53%. The fair value of the interest
rate swap agreements at December 31, 1996, is based upon current quotes for
equivalent agreements.

         These hedging activities are conducted with major financial or
commodities trading institutions which management believes entail acceptable
levels of market and credit risks. At times such risks may be concentrated with
certain counterparties or groups of counterparties. The credit worthiness of
counterparties is subject to continuing review and full performance is
anticipated.

(6)      COMMITMENTS AND CONTINGENCIES

         The Company is involved in various legal actions and claims arising in
the ordinary course of business. In the opinion of management, such litigation
and claims will be resolved without material adverse effect on the Company's
financial position.

         The Company recently received notice from two parties, each of whom
claims that it is entitled to fees from the Company based upon a Yemen oil
concession that they claim Red Eagle Resources Corporation received in August
1992, which was prior to the acquisition of Red Eagle by the Company. Based upon
the Company's examination of the available documentation relevant to such
claims, the Company believes that the claims are without merit because the
claimed oil concession was never obtained in Yemen. The Company has requested
further documentation from the two parties with respect to their claims but no
such documentation has yet been provided. The claims are for approximately $4.0
million in the aggregate (including the value of approximately 70,000 shares of
Common Stock that would be required to be issued if the oil concession had been
obtained). To date, no proceedings have been commenced with respect to either of
these claims.

         The Company leases certain office space and equipment under cancelable
and non-cancelable leases, most of which expire within 10 years and may be
renewed by the Company. Rent expense under such arrangements totaled $202,000,
$335,000 and $208,000 in 1994, 1995 and 1996 respectively. Future minimum rental
commitments under non-cancelable leases are as follows (in thousands):

(7)      EQUITY SECURITIES

         In 1993, $5,000,000 of 7-1/2% cumulative convertible exchangeable
preferred stock (the "7-1/2% Preferred Stock") was privately placed. In 1996,
the Company exercised its option and converted the 7-1/2% Preferred Stock into
576,945 shares of Common Stock.

         In November 1995, the Company sold 1,150,000 shares of $2.03
convertible exchangeable preferred stock (the "$2.03 Preferred Stock") for $28.8
million. The $2.03 Preferred Stock is convertible into the Company's common
stock at a conversion price of $9.50 per share, subject to adjustment in certain
events. The $2.03 Preferred Stock is redeemable, at the option of the Company,
at any time on or after November 1, 1998, at redemption prices beginning at
105%. At the option of the Company, the $2.03 Preferred Stock is exchangeable
for the Company's 8-1/8% convertible subordinated notes due 2005. The notes
would be subject to the same redemption and conversion terms as the $2.03
Preferred Stock

         In December 1995, the Company privately placed 1.2 million shares of
its Common Stock for $10.2 million to a state sponsored retirement plan. In
April 1996, the Company privately placed 600,000 shares of its Common Stock to a
limited number of institutional investors for approximately $6.9 million.
Warrants to acquire 40,000 shares of common stock were exercised in October
1996. Additionally, warrants to acquire 20,000 shares of Common Stock at a price
of $12.88 per share were outstanding at December 31, 1996 and will expire in May
1999.

 (8)     STOCK OPTION AND PURCHASE PLAN

         The Company maintains a Stock Option Plan which authorizes the grant of
options of up to 2.0 million shares of Common Stock. However, no new options may
be granted which would result in their being outstanding aggregate options
exceeding 10% of the Company's common shares outstanding plus those shares
issuable under convertible securities. Under the plan, incentive and
non-qualified options may be issued to officers, key employees and consultants.
The plan is administered by the Compensation Committee of the Board. All options
issued under the plan vest 30% after one year, 60% after two years and 100%
after three years. The following is a summary of stock option activity:

         In 1994, the stockholders approved the 1994 Outside Directors Stock
Option Plan (the "Directors Plan"). Only Directors who are not employees of the
Company are eligible under the Directors Plan. The Directors Plan covers a
maximum of 200,000 shares. At December 31, 1996, 76,000 options were outstanding
under the Directors Plan of which 16,800 were exercisable as of that date. The
exercise price of the options ranges from $7.75 to $13.88 per share.

         In 1994, the stockholders approved the 1994 Stock Purchase Plan (the
"1994 Plan") which authorizes the sale of up to 500,000 shares of Common Stock
to officers, directors, key employees and consultants. Under the Plan, the right
to purchase shares at pricing ranging from 50% to 85% of market value may be
granted. The Company had a 1989 Stock Purchase Plan (the "1989 Plan") which was
identical to the 1994 Plan except that it covered 333,333 shares. Upon adoption
of the 1994 Plan, the 1989 Plan was terminated. The plans are administered by
the Compensation Committee of the Board. During the year ended December 31,
1996, the Company sold 100,000 unregistered shares of Common Stock to officers
and outside directors for an aggregate amount of approximately $966,000.

         The Company has adopted the disclosure-only provisions of Statement of
Financial Accounting Standards No. 123, "Accounting for Stock Based
Compensation." Accordingly, no compensation cost has been recognized for the
stock option plans. Had compensation cost for the Corporation's two stock option
plans been determined based on the fair value at the grant date for awards in
1995 and 1996 consistent with the provisions of SFAS No. 123, the Company's net
earnings and earnings per share would have been reduced to the pro forma amounts
indicated below:

         The fair value of each option grant is estimated on the date of grant
using the Black-Scholes option pricing model with the following weighted-average
assumptions used for grants: dividend yield of 1%; expected volatility of 38%;
risk-free interest rate of 6%; and expected lives of 4 years.

(9)      BENEFIT PLAN

         The Company maintains a 401(K) Plan for the benefit of its employees.
The Plan permits employees to make contributions on a pre-tax salary reduction
basis. The Company makes discretionary contributions to the Plan. Company
contributions for 1994, 1995 and 1996 were $226,000, $346,000 and $548,000
respectively. The Company has no other employment benefit plans.

(10)     INCOME TAXES

         Federal income tax expense was $139,000, $1.8 million and $6.8 million
for the years 1994, 1995 and 1996, respectively. The current portion of the
income tax provision represents alternative minimum tax currently payable. A

         The Company follows FASB Statement No. 109, "Accounting for Income
Taxes". Under Statement 109, the liability method is used in accounting for
income taxes. Under this method, deferred tax assets and liabilities are
determined based on differences between financial reporting and tax bases of
assets and liabilities and are measured using the enacted tax rates and laws
that will be in effect when the differences are expected to reverse.

         Due to uncertainty as to the Company's ability to realize the tax
benefit, a valuation allowance was established in 1994 for the full amount of 
the net deferred tax assets. In 1995, income taxes were reduced from the
statutory rate of 34% by approximately $0.3 million through realization of a
portion of the valuation allowance, resulting in $40,000 of the allowance
remaining at each of December 31, 1995 and 1996.

         The Company has entered into several business combinations accounted
for as purchases. In connection with these transactions, deferred tax assets and
liabilities of $7.7 million and $23.8 million respectively, were recorded. In
1996 the Company acquired Eastern Petroleum Company in a taxable business
combination accounted for as a purchase. A net deferred tax liability of $2.1
million was recorded in the transaction.

         As a result of the Company's issuance of equity and convertible debt
securities, it experienced a change in control during 1988 as defined by Section
382 of the Internal Revenue Code. The change in control placed limitations to
the utilization of net operating loss carryovers. At December 31, 1996, the
Company had available for federal income tax reporting purposes net operating
loss carryovers of approximately $7.5 million which are subject to annual
limitations as to their utilization and otherwise expire between 1997 and 2010,
if unused. The Company has alternative minimum tax net operating loss carryovers
of $6.6 million which are subject to annual limitations as to their utilization
and otherwise expire from 1997 to 2009 if unused. The Company has statutory
depletion carryover of approximately $3.2 million and an alternative minimum tax
credit carryover of approximately $500,000. The statutory depletion carryover
and alternative minimum tax credit carryover are not subject to limitation or
expiration.

(11)     MAJOR CUSTOMERS

         The Company markets its oil and gas production on a competitive basis.
The type of contract under which gas production is sold varies but can generally
be grouped into three categories: (a) life-of-the-well; (b) long-term (1 year or
longer); and (c) short-term contracts which may have a primary term of one year,
but which are cancelable at either party's discretion in 30-120 days.
Approximately 60% of the Company's gas production is currently sold under market
sensitive contracts which do not contain floor price provisions. For the year
ended December 31, 1996, no one customer accounted for more than 10% of the
Company's total oil and gas revenues. Management believes that the loss of any
one customer would not have a material adverse effect on the operations of the
Company. Oil is sold on a basis such that the purchaser can be changed on 30
days notice. The price received is generally equal to a posted price set by the
major purchasers in the area. The Company sells to oil purchasers on a basis of
price and service.

(13) RELATED PARTY TRANSACTIONS

         Mr. Edelman, Chairman of the Company, is also a shareholder of Snyder
Oil Corporation ("SOCO"), and until his resignation in February 1997, was an
executive officer of SOCO. At December 31, 1996, Mr. Edelman owned 5.7% of the
Company's Common Stock. In 1995, the Company acquired SOCO's interest in certain
wells located in Appalachia for $4 million. The price was determined based on
arms-length negotiations through third-party broker retained by SOCO. Subsequent
to the transaction, the Company and SOCO no longer hold interests in any of the
same properties.

         During 1995, the Company incurred fees of $145,000 to the Hawthorne
Company in connection with acquisitions. Mr. Aikman, a director of the Company,
is an executive officer and a principal owner of the Hawthorne Company. The fees
were consistent with those paid by the Company to third parties for similar
services.

(14)     UNAUDITED SUPPLEMENTAL RESERVE INFORMATION

         The Company's proved oil and gas reserves are located in the United
States. Proved reserves are those quantities of crude oil and natural gas which,
upon analysis of geological and engineering data, can with reasonable certainty
be recovered in the future from known oil and gas reservoirs. Proved developed
reserves are those proved reserves which can be expected to be recovered from
existing wells with existing equipment and operating methods. Proved undeveloped
oil and gas reserves are proved reserves that are expected to be recovered from
new wells on undrilled acreage.

         The "Standardized Measure of Discounted Future Net Cash Flows Relating
to Proved Oil and Gas Reserves" (Standardized Measure) is a disclosure
requirement under Statement of Financial Accounting Standards No. 69
"Disclosures about Oil and Gas Producing Activities". The Standardized Measure
does not purport to present the fair market value of proved oil and gas
reserves. This would require consideration of expected future economic and
operating conditions, which are not taken into account in calculating the
Standardized Measure.

         Future cash inflows were estimated by applying year end prices to the
estimated future production less estimated future production costs based on year
end costs. Future net cash inflows were discounted using a 10% annual discount
rate to arrive at the Standardized Measure.

(15)     COMETRA ACQUISITION

         Effective January 1, 1997, the Company acquired oil and gas properties
located in West Texas, South Texas and the Gulf of Mexico (the "Cometra
Properties") from American Cometra, Inc. ("Cometra") for a purchase price of
$385 million, subject to adjustment (the "Cometra Acquisition"). The Cometra
Acquisition increases the Company's pro forma proved reserves at December 31,
1996 by 68% to 644 Bcfe and increases its Present Value by 98% to $974 million.
The Cometra Properties, located primarily in the Company's core operating areas,
include 515 producing wells, and additional development and exploration
potential on approximately 150,000 gross acres (90,000 net acres). In addition,
the Cometra Properties include gas pipelines, a 25,000 Mcf/d gas processing
plant and an above-market gas contract with a major Texas gas utility covering
approximately 30% of the current production from the Cometra Properties.

         The Company will finance the cash portion of the purchase price with
$221 million of borrowings through expansion of its bank credit facility (the
"Amended Credit Facility") and the issuance to Cometra of a $134 million
non-interest bearing promissory note due March 31, 1997, which is secured by a
bank letter of credit. The promissory note will be repaid at maturity through
borrowings under the Amended Credit Facility. The Amended Credit Facility will
enable the Company to obtain revolving credit loans and issue letters of credit
from time to time in an aggregate amount not to exceed $400 million initially.
Availability under the Amended Credit Facility was reduced to $300 million upon
the consummation of the Offerings. The Amended Credit Facility provides for a
Borrowing Base which is subject to semi-annual determinations and certain other
redeterminations. Security obligations in place with the Credit Agreement were
released upon the consummation of the Offerings on March 14, 1997.

         The Amended Credit Facility bears interest at either the Alternate Base
Rate (as defined) plus a margin ranging from 0% to 0.25% or the Eurodollar loan
rate plus margin ranging from 0.625% to 1.125%. Interest is payable quarterly
and the Amended Credit Facility matures in February 2002.

         The Amended Credit Facility includes various covenants that require,
among other things, that the Company (i) maintain a minimum consolidated
tangible net worth of at least $100 million plus 90% of the net proceeds from
the Common Stock offering described below and 50% of the net proceeds from any
subsequent equity offering; (ii) maintain a ratio of EBITDA to consolidated
interest expense on total debt for each period of four consecutive fiscal
quarters of at least 2.5 to 1.0; and (iii) not make restricted payments (defined
as dividends, distributions or guarantees to third parties or the retirement,
repurchase or prepayment prior to the scheduled maturity of its subordinated
debt) in an aggregate amount in any one fiscal year in excess of $5 million plus
50% of the net proceeds from equity offerings subsequent to the Common Stock
offering described below and 50% of the Company's consolidated net income earned
after January 1, 1997. In addition, the Amended Credit Facility will restrict
the ability of the Company to dispose of assets, incur additional indebtedness,
repay other indebtedness or amend other debt instruments, create liens on
assets, make investments or acquisitions, engage in mergers or consolidations,
make capital expenditures or engage in certain transactions with affiliates.

         In January 1997, the Company filed a registration statement with the
Securities and Exchange Commission as amended, the registration statement
covered the sale of 4 million shares of Common Stock and $125 million aggregate
principal amount of ten year senior subordinated notes. On March 14, 1997, the
Offerings were consummated and the Company received proceeds of approximately
$186 million, after deducting underwriting discounts and estimated expenses.
The proceeds from the Offerings were used to repay indebtedness incurred under
the Amended Credit Facility in connection with the Cometra Acquisition. The
notes are guaranteed by all of the subsidiaries of the Company and each
guarantor is a wholly owned subsidiary of the Company. The guarantees are full,
unconditional and joint and several. Separate financial statements of each
guarantor are not presented because they are included in the consolidated
financial statements of the Company and management has concluded that they
provide no additional benefits.

ARTICLE 2 - AMOUNT AND TERMS OF COMMITMENTS.
- --------------------------------------------

         2.01. COMMITMENTS. (a) Subject to the terms and conditions hereof, each
Lender severally agrees to make revolving loans (the "LOANS") to Borrower from
time to time during the Commitment Period in an aggregate principal amount not
to exceed at any one time outstanding the amount of that Lender's Commitment
reduced by an amount equal to that Lender's Participating Interests in Letters
of Credit then outstanding; PROVIDED, THAT, no Lender will make Loans if, after
giving effect thereto, the Outstanding Obligations would exceed the lesser of
(i) the Total Commitment or (ii) the Borrowing Base then in effect. During the
Commitment Period, Borrower may use the Commitments by borrowing, prepaying the
Loans in whole or in part, and reborrowing all in accordance with the terms and
conditions hereof.

         (b) The Loans may be outstanding as ABR Loans or Eurodollar Loans or a
combination thereof, as determined by Borrower and notified to Administrative
Agent in accordance with SECTIONS 2.02 and 2.07; PROVIDED, THAT, no Loan shall
be made as a Eurodollar Loan after the day that is one month before the
Termination Date. Each type of Loan shall be made and maintained at each
Lender's Lending Office for that type of Loan. The failure of any Lender to make
any requested Loan to be made by it on the 




                            CREDIT AGREEMENT-Page 16
<PAGE>   17



Borrowing Date specified for that Loan shall not relieve the other Lenders of
their obligation (if any) to make Loans on that date, but no Lender shall be
responsible for the failure of the other Lenders to make Loans to be made by the
other Lender. Each Borrowing shall (i) be in a minimum principal amount of
$1,000,000 or any larger integral multiple of $100,000 (except that any ABR Loan
may be in the amount of the unused portion of the Total Commitment) and (ii) be
made from each Lender ratably in accordance with its respective Commitment
Percentage. Notwithstanding any provision of this Agreement or the Loan
Documents to the contrary, on the Closing Date and continuously until repayment
in full of all Loans or the termination of this Agreement, whichever occurs
first, there shall be and remain outstanding Loans of not less than $1,000, the
balance of which may not be prepaid.

         2.02. PROCEDURE FOR BORROWING. (a) To request a Borrowing hereunder,
Borrower shall hand deliver or telecopy to Administrative Agent a Notice of
Borrowing in the form of EXHIBIT F hereto (a "NOTICE OF BORROWING") prior to
1:00 p.m. (Fort Worth, Texas time) at least one Business Day before the
requested Borrowing Date of each ABR Borrowing, and at least three Business Days
before the Borrowing Date of each Eurodollar Borrowing. Each Notice of Borrowing
shall specify (1) the Borrowing Date; (2) the aggregate amount of the Borrowing
requested; (3) whether such Borrowing is to be an ABR Borrowing or a Eurodollar
Borrowing, and (4) in the case of a Eurodollar Borrowing, the duration of the
Interest Period applicable thereto. Administrative Agent shall promptly notify
each Lender of Borrower's request, and not later than 12:00 noon (Fort Worth,
Texas time), on the Borrowing Date, each Lender will make available to
Administrative Agent at 500 Throckmorton Street, Fort Worth, Texas 76102, in
immediately available funds, that Lender's Commitment Percentage of the
aggregate amount of such Borrowing. After Administrative Agent's receipt of
these funds, not later than 2:00 p.m. (Fort Worth, Texas time) on the Borrowing
Date and upon fulfillment of the applicable conditions set forth in Article 6,
Administrative Agent will make the proceeds of such Borrowing available to
Borrower in immediately available funds by crediting the amount thereof to
Borrower's account with Administrative Agent.

                  (b) All notices given by Borrower under this SECTION 2.02
shall be irrevocable and shall be given not later than 1:00 p.m. (Fort Worth,
Texas time) on a day which is not less than the number of Business Days
specified above for the notice.

         2.03. NOTES. (a) All Loans made by each Lender shall be evidenced by,
and repaid with interest in accordance with a single promissory note of Borrower
(a "NOTE"), which shall be (i) in substantially the form of attached EXHIBIT B,
duly completed; (ii) be dated the date hereof; (iii) be in a face amount equal
to that Lender's Commitment; (iv) be payable to the order of that Lender for the
account of its applicable Lending Office; and (v) bear interest in accordance
with SECTION 2.04 hereof. Notwithstanding the principal amount of each Lender's
Note as stated on the face thereof, the amount of principal actually owing on
that Lender's Note at any given time shall be the aggregate of that Lender's
Loans made to Borrower, less all payments of principal actually received by such
Lender. The Loans shall mature on the Termination Date.

         (b) Simultaneously with the execution of this Agreement, Administrative
Agent shall deliver to each Lender the Note payable to that Lender referenced in
SECTION 2.03(A). Each Lender may endorse (and prior to any transfer of its Note
shall endorse) on the schedule attached to the Note held by that Lender
appropriate notations to evidence the date and amount of each Loan made by it,
the Interest Period applicable thereto, and the date and amount of each payment
of principal of any Loan made by Borrower with respect thereto, PROVIDED, THAT,
the failure by any Lender to so endorse its Note shall not affect the liability
of Borrower for the repayment of all amounts outstanding under the Note together
with interest thereon. Each Lender is hereby irrevocably authorized by Borrower
to endorse its Note and to attach to and make a part of any Note a continuation
of any such schedule as required.

         2.04. INTEREST RATES AND PAYMENT DATES. Borrower shall pay interest to
Administrative Agent for the account of each Lender on the outstanding and
unpaid principal amount of that Lender's Loans made under this Agreement at a
rate per annum as follows:



                            CREDIT AGREEMENT-Page 17
<PAGE>   18



                   (a) For each ABR Loan, at a rate equal to the sum of the
Adjusted Base Rate in effect from day to day plus the Applicable Margin,
PROVIDED THAT in no event will the rate charged hereunder or under any Note
exceed the Maximum Lawful Rate. Interest which accrues on each ABR Loan shall be
payable in arrears on the first day of January, April, July, and October of each
year.

                  (b) For each Eurodollar Loan, for the Interest Period
applicable thereto, at a rate equal to the sum of the Eurodollar Rate plus the
Applicable Margin, PROVIDED THAT in no event will the rate charged hereunder or
under any Note exceed the Maximum Lawful Rate. Interest which accrues on each
Eurodollar Loan shall be payable in arrears on the expiration of each applicable
Interest Period and, in the case of any Eurodollar Loan with an Interest Period
of longer than three months, at the expiration of each three-month period during
such Interest Period.

                  (c) Administrative Agent shall determine each interest rate
applicable to the Loans in accordance with the terms hereof. Administrative
Agent shall promptly notify Borrower and Lenders of each rate of interest so
determined, and its determination thereof shall be conclusive in the absence of
manifest error.

                  (d) Notwithstanding the foregoing, if at any time the rate of
interest calculated with reference to the Adjusted Base Rate or the Eurodollar
Rate hereunder (the "CONTRACT RATE") is limited to the Maximum Lawful Rate, any
subsequent reductions in the contract rate shall not reduce the rate of interest
on the affected Loan below the Maximum Lawful Rate until the total amount of
interest accrued equals the amount of interest which would have accrued if the
contract rate had at all times been in effect. In the event that at maturity
(stated or by acceleration), or at final payment of a Note, the total amount of
interest paid or accrued on such Note is less than the amount of interest which
would have accrued if the contract rate had at all times been in effect with
respect thereto, then at that time, to the extent permitted by law, Borrower
shall pay to the holder of the Note an amount equal to the difference between
(i) the lesser of the amount of interest which would have accrued if the
contract rate had at all times been in effect and the amount of interest which
would have accrued if the Maximum Lawful Rate had at all times been in effect,
and (ii) the amount of interest actually paid on such Note.

                  (e) Any change in the interest rate on a Loan resulting from a
change in the Adjusted Base Rate or the Eurodollar Reserve Percentage shall be
effective as of the opening of business on the Business Day on which the change
becomes effective. Interest on the unpaid principal of (i) each Eurodollar Loan
shall be calculated on the basis of the actual days elapsed in a year consisting
of 360 days (except to the extent that such calculation would result in a
usurious rate, in which case a year consisting of 365 or 366 days, as the case
may be, shall be used), and (ii) each ABR Loan shall be calculated on the basis
of the actual days elapsed in a year consisting of 365 days or 366 days, as the
case may be.

                  (f) Any overdue principal of and, to the extent permitted by
law, overdue interest on any Loan (after giving effect to all grace periods)
shall bear interest payable on demand, for each day until paid at a rate per
annum equal to the lesser of (i) the sum of the Adjusted Base Rate plus (x) 5%
until the occurrence of the Trigger Event and (y) 2% after the occurrence of the
Trigger Event; and (ii) the Maximum Lawful Rate.

         2.05. NON-RECEIPT OF FUNDS BY ADMINISTRATIVE AGENT. (a) Unless
Administrative Agent receives written notice from a Lender prior to the
Borrowing Date applicable to a Borrowing that such Lender will not make the
amount that would constitute its Commitment Percentage of the Borrowing,
available to Administrative Agent, Administrative Agent may assume that Lender
will make the funds available to Administrative Agent on the Borrowing Date, and
Administrative Agent may, but shall not be obligated to, in reliance upon that
assumption, make available to Borrower on the Borrowing Date a corresponding
amount. If such Lender has not made the funds available to Administrative Agent,
by the required time on the applicable Borrowing Date, that Lender agrees to
repay to Administrative Agent, immediately on demand, the corresponding amount
together with interest thereon, for each day from the date the amount is made
available to Borrower until the date the amount is repaid to Administrative
Agent, at the Federal 



                            CREDIT AGREEMENT-Page 18
<PAGE>   19




Funds Rate for three Business Days and thereafter at the Adjusted Base Rate. If
such Lender shall repay to Administrative Agent the corresponding amount, the
amount so repaid shall constitute such Lender's Loan for purposes of this
Agreement. If such Lender does not pay the corresponding amount immediately upon
Administrative Agent's demand therefor, Administrative Agent shall promptly
notify Borrower, and Borrower shall immediately pay the corresponding amount to
Administrative Agent with interest thereon, for each day from the date the
amount is made available to Borrower until the date the amount is repaid to
Administrative Agent, at the rate of interest applicable at the time to the
proposed Loan.

                  (b) Unless Administrative Agent receives notice from Borrower
prior to the date on which any payment is due to Lenders hereunder that Borrower
will not make the payment in full, Administrative Agent may assume that Borrower
has made the payment in full to Administrative Agent on that date, and
Administrative Agent in its sole discretion may, but is not be obligated to, in
reliance upon this assumption, cause to be distributed to each Lender on that
due date an amount equal to the amount then due that Lender. If and to the
extent Borrower does not make the payment in full to Administrative Agent, each
Lender shall repay to Administrative Agent immediately on demand the amount
distributed to that Lender together with interest thereon, for each day from the
date the amount is distributed to such Lender until the date the Lender repays
the amount to Administrative Agent, at the Federal Funds Rate for three Business
Days and thereafter at the Adjusted Base Rate.

         2.06. USE OF PROCEEDS. Subject to the satisfaction of each condition
precedent set forth in SECTION 6.01 hereof, all Loans and Letters of Credit
outstanding under the Existing Credit Agreement shall be deemed to be
outstanding hereunder and shall constitute Loans and Letter of Credit
Outstandings hereunder. The proceeds of the Loans made on and after the Closing
Date shall be used (a) to refinance the indebtedness outstanding under the
Existing Credit Agreement, (b) to purchase the Cometra Assets, (c) for the
payment of capital expenditures, drilling costs, and other expenses incurred by
Borrower and its Subsidiaries in the further development and exploration of
Borrower's Oil and Gas Properties, (d) to purchase additional oil and gas
properties, (e) for working capital and general corporate purposes, but only to
the extent that the use of proceeds for these purposes would be permitted under
the terms of this Agreement, (f) to fund reimbursement obligations with respect
to Letters of Credit, and (g) for Permitted Investments, but excluding Capital
Stock of publicly traded companies. Borrower assumes all obligations of the
other Existing Borrowers with respect to the Existing Rights and Obligations.

         2.07. CONVERSIONS AND RENEWALS. Borrower may elect from time to time to
convert all or a part of one type of Loan into another type of Loan or to renew
all or part of a Loan by giving Administrative Agent written notice thereof by
12:00 noon (Fort Worth, Texas time) at least one Business Day before the
conversion into an ABR Loan and at least three Business Days before the
conversion into or renewal of a Eurodollar Loan, specifying: (a) the renewal or
conversion date; (b) the amount of the Loan to be converted or renewed; and (c)
in the case of conversions, the type of Loan to be converted into; and (d) in
the case of renewals of or a conversion into Eurodollar Loans, the duration of
the Interest Period applicable thereto; provided that (i) the minimum principal
amount of all Eurodollar Loans outstanding and subject to the same Interest
Period after a renewal or conversion shall be $1,000,000 or any larger integral
multiple of $100,000; and (ii) Eurodollar Loans can be converted to ABR Loans
only on the last day of the Interest Period applicable thereto. All notices
given by Borrower under this SECTION 2.07 shall be irrevocable and shall be in
the form of EXHIBIT G hereto (a "ROLLOVER NOTICE"). If Borrower fails to give
Administrative Agent the notice as specified above for the renewal or conversion
of a Eurodollar Loan prior to the end of the Interest Period with respect
thereto, that Eurodollar Loan shall automatically be converted into an ABR Loan
on the last day of the Interest Period for the Loan.

         2.08. LIMITATION ON NUMBER OF EURODOLLAR LOANS. There may be no more
than an aggregate of ten Interest Periods applicable to outstanding Eurodollar
Loans in effect at any time, unless otherwise agreed by Lenders.

         2.09. PREPAYMENTS. (a) Borrower may, without premium or penalty, upon
one Business Days' prior written notice to Administrative Agent, prepay the
Notes, in whole or in part, with accrued interest 



                            CREDIT AGREEMENT-Page 19
<PAGE>   20



to the date of the prepayment on the amount prepaid, provided that (i) each
prepayment of less than the full outstanding principal balance of the Notes
shall be in a minimum amount equal to $1,000,000 or any larger integral multiple
of $100,000; and (ii) if Borrower prepays the principal of any Eurodollar Loan
on any date other than the last day of the Interest Period applicable thereto,
Borrower shall also pay to Lenders the amounts specified in SECTION 10.06. Upon
receipt of any prepayments, Administrative Agent will promptly thereafter cause
to be distributed the prepayment to each Lender for the account of its
applicable Lending Office in the proportion that each Lender's Loan to which the
prepayment applies bears to the total amount of all Lenders' Loans to which the
prepayment applies.

                  (b) Borrower shall make a mandatory prepayment on the Loans
(i) simultaneously with any reduction in the Borrowing Base pursuant to SECTION
4.05 hereof in an amount sufficient to eliminate any Borrowing Base Deficiency
resulting from such prepayment, and (ii) at each other time required by SECTION
4.06 hereof as a result of any Borrowing Base Deficiency.

                  (c) Any voluntary prepayment of a Eurodollar Loan hereunder
shall be (i) made together with interest accrued (through the date of the
prepayment) on the principal amount prepaid and (ii) applied first to accrued
interest and then to principal.

         2.10. MANNER AND APPLICATION OF PAYMENTS. (a) All payments of principal
of, and interest on, any Note shall be made by Borrower to Administrative Agent
before 1:00 p.m. (Fort Worth, Texas time), in federal or other immediately
available funds, at Administrative Agent's office at 500 Throckmorton Street,
Fort Worth, Texas 76102, for the account of the applicable Lending Office of
each Lender. Should the principal of, or any installment of the principal or
interest on, any Note, or any commitment fee, become due and payable on a day
other than a Business Day, the maturity thereof shall be extended to the next
succeeding Business Day. Whenever any payment to be made under this Agreement or
under any Note shall be stated to be due on a day other than a Business Day, the
payment shall be made on the next succeeding Business Day, and the extension of
time shall be included in the computation of the payment of interest and the
commitment fee, as the case may be, except, in the case of a Eurodollar Loan, if
the result of the extension would be to extend the payment into another calendar
month, the payment shall be made on the immediately preceding Business Day. All
payments made under the Loan Documents shall be credited, to the extent of the
amount thereof, in the following manner: (i) first to fees, costs and expenses
which Borrower has agreed to pay under the Loan Documents; (ii) second, against
the amount of interest accrued and unpaid on the Notes as of the date of the
payment; (iii) third, against all principal (if any) due and owing on the Notes
as of the date of the payment; (iv) fourth, as a prepayment of outstanding ABR
Loans under the Notes; (v) fifth, as a prepayment of outstanding Eurodollar
Loans under the Notes; and (vi) sixth, as a prepayment of any remaining
Obligation. Subject to the foregoing, Borrower shall select ABR Loans and
Eurodollar Loans to be repaid in a manner designated to minimize the loss to
each Lender, if any, resulting from the payments; PROVIDED, HOWEVER, that, if
Borrower fails to select the ABR Loans and Eurodollar Loans to which the
payments are to be applied, or if an Event of Default has occurred and is
continuing at the time of the payment, then each Lender shall be entitled to
apply the payment to ABR Loans and Eurodollar Loans in the manner it shall deem
appropriate.

                  (b) On the Business Day of receipt by Administrative Agent, if
Administrative Agent's receipt occurs before 1:00 p.m. (Fort Worth, Texas time),
Administrative Agent will promptly thereafter cause to be distributed, on the
same Business Day, (1) the payments of principal and interest in like funds to
each Lender for the account of its applicable Lending Office pro rata according
to the respective outstanding principal amounts of the Loans to which the
payment applies then held by Lenders and (2) other fees payable to any Lender to
be applied in accordance with the terms of this Agreement. All payments received
by Administrative Agent after 1:00 p.m. (Fort Worth, Texas time) will be
distributed promptly by Administrative Agent, and in no event later than 2:00
p.m. (Fort Worth, Texas time) of the next succeeding Business Day. Borrower
authorizes each Lender, if and to the extent payment is not made when due under
this Agreement or under any Note, to charge from time to time against any
account of Borrower with that Lender other than a Special Account any amount as
due.

<PAGE>   21



         2.11. VOLUNTARY REDUCTION OF COMMITMENT. Borrower may, by notice to
Administrative Agent five Business Days prior to the effective date of any such
reduction, reduce the Total Commitment (and thereby reduce the Commitment of
each Bank ratably) in amounts not less than $1,000,000 and in any amount which
is an integral multiple of $100,000. On the effective date of any such
reduction, Borrower shall, to the extent required as a result of such reduction,
make a principal prepayment on the Loans in an amount sufficient to cause the
Outstanding Obligations to be equal to or less than the Total Commitment as
thereby reduced. Notwithstanding the foregoing, Borrower shall not be permitted
to voluntarily reduce the Total Commitment to an amount less than the Letter of
Credit Outstandings.

ARTICLE 3 - LETTERS OF CREDIT.
- ------------------------------

         3.01. LETTERS OF CREDIT. (a) Subject to the terms and conditions
hereof, the Issuing Lender selected by Borrower, in reliance on the agreements
of the other Lenders set forth in SECTION 3.04(A), agrees to issue letters of
credit ("LETTERS OF CREDIT") for the account of Borrower on any Business Day
during the Commitment Period in such form as may be approved from time to time
by the Issuing Lender; PROVIDED that Issuing Lender shall not issue any Letter
of Credit if, after giving effect to the issuance and after giving effect to any
Borrowing requested to be made or Letters of Credit requested to be issued on
that date, (i) the Letter of Credit Outstandings would exceed $150,000,000
through the earlier of (A) April 30, 1997, or (B) any earlier cancellation,
termination, or payment of the Cometra Letter of Credit, and $100,000,000
thereafter or (ii) the Outstanding Obligations would exceed the lesser of (x)
the Total Commitment or (y) the Borrowing Base then in effect. Each Letter of
Credit shall (i) be issued to support obligations of Borrower or any of its
Subsidiaries contingent or otherwise, which finance the working capital and
business needs of Borrower and its Subsidiaries, and (ii) shall expire no later
than the earlier of (x) one year after the date of issuance or (y) five Business
Days prior to the Termination Date. Each Letter of Credit shall be denominated
in dollars.

                  (b) Each Letter of Credit shall be subject to the Uniform
Customs and Practice for Documentary Credits (1995 Revision), International
Chamber of Commerce Publication No. 500, as the same may be amended from time to
time, and, to the extent not inconsistent therewith, the laws of the State of
Texas.

                  (c) The Issuing Lender shall not at any time be obligated to
issue any Letter of Credit hereunder if the issuance would conflict with, or
cause the Issuing Lender or any Participating Lender to exceed any limits
imposed by, any applicable law.

         3.02. PROCEDURE FOR ISSUANCE OF LETTERS OF CREDIT. Borrower may from
time to time request that the Issuing Lender issue a Letter of Credit by
delivering to the Issuing Lender and Administrative Agent at their respective
addresses for notices specified herein a Request for Letter of Credit in the
form of EXHIBIT H hereto, together with a letter of credit application in the
Issuing Lender's then customary form (a "LETTER OF CREDIT APPLICATION")
completed to the satisfaction of the Issuing Lender, and the other certificates,
documents, and other papers and information as may be customary and as the
Issuing Lender may reasonably request. Upon receipt of any Letter of Credit
Application, the Issuing Lender will process the Letter of Credit Application
and the certificates, documents, and other papers and information delivered to
it in connection therewith in accordance with its customary procedures and, upon
receipt by the Issuing Lender of confirmation from Administrative Agent that
issuance of the Letter of Credit will not contravene SECTION 3.01, the Issuing
Lender shall promptly issue the Letter of Credit requested thereby (but in no
event shall the Issuing Lender be required to issue any Letter of Credit earlier
than three Business Days after its receipt of the Letter of Credit Application
therefor and all certificates, documents, and other papers and information
relating thereto) by issuing the original of the Letter of Credit to the
beneficiary thereof or as otherwise may be agreed by the Issuing Lender and
Borrower. The Issuing Lender shall furnish a copy of the Letter of Credit to
Borrower and Administrative Agent promptly following the issuance thereof, and,
thereafter, Administrative Agent shall promptly furnish a copy thereof to
Lenders.



                            CREDIT AGREEMENT-Page 21
<PAGE>   22




         3.03. FEES, COMMISSIONS, AND OTHER CHARGES. (a) Borrower shall pay to
Administrative Agent, for the account of the Issuing Lender and the
Participating Lenders, a letter of credit commission with respect to each Letter
of Credit on the average daily aggregate amount available to be drawn under such
Letter of Credit during the relevant period equal to the greater of (x) $500 or
(y) an amount calculated for the period from the date the Letter of Credit is
issued to the date upon which the payment is due under this SECTION 3.03 (and,
thereafter, from the date of prior payment under this SECTION 3.03 to the date
upon which the payment is due under this section) at a rate per annum equal to
the Applicable Margin in effect on the date such payment is due with respect to
Eurodollar Loans MINUS .125%, based upon the actual number of days that such
Letter of Credit is outstanding. Borrower also shall pay to Administrative
Agent, for the account of the Issuing Lender, a letter of credit commission with
respect to each Letter of Credit in an amount equal to .125% per annum of the
stated amount of the Letter of Credit, based upon the actual number of days that
such Letter of Credit is outstanding. The Letter of Credit commissions payable
pursuant to the first sentence of this section shall be payable quarterly in
arrears on the first day of each January, April, July, and October, commencing
April 1, 1997, and on the Termination Date. The letter of credit commissions
payable pursuant to the second sentence of this section shall be payable in
arrears on the first day of each January, April, July, and October, commencing
April 1, 1997, on the date such Letter of Credit is extended, and on the
Termination Date.

                  (b) In addition to the foregoing fees and commissions,
Borrower shall pay or reimburse the Issuing Lender for all normal and customary
costs and expenses as are incurred or charged by the Issuing Lender in issuing,
effecting payment under, amending, or otherwise administering any Letter of
Credit.

                  (c) Administrative Agent shall, promptly following its receipt
thereof, distribute to the Issuing Lender and the Participating Lenders all fees
and commissions received by Administrative Agent for their respective accounts
pursuant to this subsection.

         3.04. LETTER OF CREDIT PARTICIPATION. (a) Effective on the date of
issuance of each Letter of Credit (including, without limitation, each Existing
Letter of Credit which is deemed issued on the Closing Date), the Issuing Lender
irrevocably agrees to grant and hereby grants to each Participating Lender, and
each Participating Lender irrevocably agrees to accept and purchase and hereby
accepts and purchases from the Issuing Lender, on the terms and conditions
hereinafter stated, for the Participating Lender's own account and risk, an
undivided interest equal to the Participating Lender's Commitment Percentage in
the Issuing Lender's obligations and rights under each Letter of Credit issued
by the Issuing Lender and the amount of each draft paid by the Issuing Lender
thereunder. Each Participating Lender unconditionally and irrevocably agrees
with the Issuing Lender that, if a draft is paid under any Letter of Credit for
which the Issuing Lender is not reimbursed in full by Borrower in accordance
with the terms of this Agreement, the Participating Lender shall pay to
Administrative Agent, for the account of the Issuing Lender, upon demand at
Administrative Agent's address specified in SECTION 12.10, an amount equal to
the Participating Lender's Commitment Percentage of the amount of the draft, or
any part thereof, which is not so reimbursed. On the date that any assignee
becomes a Lender party to this Agreement in accordance with SECTION 12.08,
participating interests in any outstanding Letters of Credit held by the
transferor Lender from which the assignee acquired its interest hereunder shall
be proportionately reallotted between the assignee and the transferor Lender.
Each Participating Lender hereby agrees that its obligation to participate in
each Letter of Credit, and to pay or to reimburse the Issuing Lender for its
participating share of the drafts drawn or amounts otherwise paid thereunder, is
absolute, irrevocable, and unconditional and shall not be affected by any
circumstances whatsoever (including, without limitation, the occurrence or
continuance of any Default or Event of Default), and that each payment shall be
made without offset, abatement, withholding, or other reduction whatsoever.

                  (b) If any amount required to be paid by any Participating
Lender to the Issuing Lender pursuant to SECTION 3.04(A) in respect of any
unreimbursed portion of any draft paid by the Issuing Lender under any Letter of
Credit is paid to the Issuing Lender within three Business Days after the date
the payment is due, the Participating Lender also shall pay to Administrative
Agent, for the account of the 




                            CREDIT AGREEMENT-Page 22
<PAGE>   23



Issuing Lender, on demand, an amount equal to the product of (i) that amount,
times (ii) the daily average Federal Funds Rate during the period from and
including the date the draft is paid to the date on which the payment is
immediately available to the Issuing Lender, times (iii) a fraction the
numerator of which is the number of days that elapsed during that period and the
denominator of which is 360. If any amount required to be paid by any
Participating Lender pursuant to SECTION 3.04(A) is not in fact made available
to Administrative Agent, for the account of the Issuing Lender, by the
Participating Lender within three Business Days after the date the payment is
due, the Issuing Lender shall be entitled to recover from the Participating
Lender, on demand, the amount with interest thereon calculated from the due date
at the Adjusted Base Rate A certificate of the Issuing Lender submitted to any
Participating Lender with respect to any amounts owing under this section shall
be conclusive in the absence of manifest error.

                  (c) Whenever, at any time after the Issuing Lender has paid a
draft under any Letter of Credit and has received from any Participating Lender
its PRO RATA share of the payment in accordance with SECTION 3.04(A), the
Issuing Lender receives any reimbursement on account of the unreimbursed
portion, or any payment of interest on account thereof, the Issuing Lender will
pay to Administrative Agent, for the account of the Participating Lender, its
PRO RATA share thereof; PROVIDED, HOWEVER, that in the event that any the
payment received by the Issuing Lender shall be required to be returned by the
Issuing Lender, the Participating Lender shall return to Administrative Agent
for the account of the Issuing Lender, the portion thereof previously
distributed to it.

         3.05. REIMBURSEMENT OBLIGATION OF BORROWER. If any draft is presented
for payment under any Letter of Credit, the Issuing Lender shall notify Borrower
and Administrative Agent of the date and the amount thereof. Borrower agrees to
reimburse the Issuing Lender (whether with its own funds or with proceeds of
Loans), within two Business Days after notice that the Issuing Lender paid a
draft so presented under any Letter of Credit, for the amount of (i) the draft
so paid and (ii) any taxes, fees, charges, or other costs or expenses incurred
by the Issuing Lender in connection with the payment. Each payment shall be made
to the Issuing Lender at its address for notices specified herein in lawful
money of the United States of America and in immediately available funds.
Interest shall be payable on any and all amounts remaining unpaid by Borrower
under this subsection from the date of payment of the applicable draft until
payment in full thereof, (x) for the period commencing on the date of payment of
the applicable draft to the date which is three days after notice of payment of
the draft, at the Adjusted Base Rate at that time and (y) thereafter, at the
Adjusted Base Rate at that time plus 5% until the occurrence of the Trigger
Event and after the Trigger Event at the Adjusted Base Rate at that time plus
2%.

         3.06. OBLIGATIONS ABSOLUTE. (a) Borrower's obligations under this
Article 3 shall be absolute and unconditional under any and all circumstances
and irrespective of any setoff, counterclaim, or defense to payment which
Borrower or any other Person may have or have had against the Issuing Lender or
any other Lender or any beneficiary of a Letter of Credit. Borrower also agrees
with the Issuing Lender that the Issuing Lender shall not be responsible for,
and Borrower's obligations under SECTION 3.05 shall not be affected by, among
other things, the validity or genuineness of documents or of any endorsements
thereon which on its face appears valid, even though the documents shall in fact
prove to be invalid, fraudulent, or forged, or any dispute between or among
Borrower and any beneficiary of any Letter of Credit or any other party to which
the Letter of Credit may be transferred or any claims whatsoever of Borrower
against any beneficiary of the Letter of Credit or any the transferee. The
Issuing Lender shall not be liable for any error, omission, interruption, or
delay in transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit, except for errors or
omissions caused by the Issuing Lender's gross negligence or willful misconduct.
Borrower agrees that any action taken or omitted by the Issuing Lender under or
in connection with any Letter of Credit or the related drafts or documents, if
done in the absence of gross negligence or willful misconduct and in accordance
with the standards of care specified in the Uniform Commercial Code of the State
of Texas, including, without limitation, Article V thereof, shall be binding on
Borrower and shall not result in any liability of the Issuing Lender to
Borrower.


                            CREDIT AGREEMENT-Page 23
<PAGE>   24




                  (b) Without limiting the generality of the foregoing, it is
expressly agreed that the absolute and unconditional nature of Borrower's
obligations under this Article 3 to reimburse the Issuing Lender for each
drawing under a Letter of Credit will not be excused by the gross negligence or
willful misconduct of the Issuing Lender. However, the foregoing shall not be
construed to excuse the Issuing Lender from liability to Borrower to the extent
of any direct damages (as opposed to consequential damages, claims in respect of
which are hereby waived by Borrower to the extent permitted by applicable law)
suffered by Borrower that are caused by the Issuing Lender's gross negligence or
willful misconduct in determining whether drafts and other documents presented
under a Letter of Credit comply with the terms thereof.

         3.07. LETTER OF CREDIT PAYMENTS. Without limitation of SECTION 3.06,
the responsibility of the Issuing Lender to Borrower in connection with any
draft presented for payment under any Letter of Credit shall, in addition to any
payment obligation expressly provided for in the Letter of Credit, be limited to
determining that the documents (including each draft) delivered under the Letter
of Credit in connection with the presentment are in conformity with the Letter
of Credit.

         3.08. LETTER OF CREDIT APPLICATIONS. To the extent that any provision
of any Letter of Credit Application, including any reimbursement provisions
contained therein, related to any Letter of Credit is inconsistent with the
provisions of this Article 3, the provisions of this Article 3 shall prevail.

         3.09. CASH COLLATERALIZATION OF LETTERS OF CREDIT. Upon request of
Administrative Agent after the occurrence and during the continuance of an Event
of Default and at any time required to eliminate any Borrowing Base Deficiency
pursuant to SECTION 4.06 hereof, Borrower shall deposit cash with Administrative
Agent in an amount equal to the aggregate Letter of Credit Outstandings (or, in
the event of a Borrowing Base Deficiency in the amount required pursuant to
SECTION 4.06). Such amount so deposited shall be held by Administrative Agent
for the ratable benefit of all Lenders as security for the Letter of Credit
Outstandings and other Obligations, and Borrower will, in connection therewith,
deliver such security agreements in form and substance satisfactory to
Administrative Agent which it may, in its discretion require. As drafts or
demands are presented under any Letter of Credit, Administrative Agent shall
disburse such cash to the applicable Issuing Lender to the extent necessary to
satisfy Borrower's reimbursement obligations in connection therewith. To the
extent drafts or other demands for payment are not made prior to the expiration
date for any Letter of Credit, Administrative Agent agrees, if no Event of
Default has occurred and is continuing, to remit to Borrower cash in the amount
deposited under this SECTION 3.09 for which the contingent obligations evidenced
by such Letter of Credit have ceased. When all Letters of Credit have expired or
been canceled, and all Letter of Credit Obligations and other Obligations have
been paid in full and all Commitments have been terminated (or any Borrowing
Base Deficiency has been eliminated to the extent such cash collateralization is
required as a result of Borrowing Base Deficiency) Administrative Agent shall
release any remaining cash deposited under this SECTION 3.09 to Borrower.

<PAGE>   25



ARTICLE 4 - BORROWING BASE
- --------------------------

         4.01. DETERMINATION OF BORROWING BASE. (a) The term "BORROWING BASE"
means the designated loan value of Borrower's Oil and Gas Properties as
determined by Agents in their sole discretion and approved by Required Lenders
in their sole discretion, in each case in accordance with their respective
then-current practices, customary procedures and standards for their respective
petroleum industry customers, and utilizing (i) the pertinent economic
parameters customarily used by each Lender with respect to credits of a similar
size and nature, and (ii) the information that the Lenders have available to
them at the time of each determination, including, without limitation, assets,
liabilities, cash flow and other financial information regarding Borrower and
its Subsidiaries, the Collateral and the business, properties, prospects,
management, and ownership of the Borrower and its Subsidiaries. The Borrowing
Base in effect under this Agreement shall be redetermined at the times set forth
in SECTION 4.02, 4.03, and 4.04 and in accordance with the procedures set forth
in SECTION 4.01(B). Until the Commitments of all Banks have terminated, all
Letters of Credit have expired or been canceled, and all Obligations have been
paid in full, amounts outstanding under this Agreement shall be subject to the
then effective Borrowing Base.

         (b) Not later than ten Business Days prior to each Determination Date
applicable to any redetermination of the Borrowing Base, (i) Agents shall agree
among themselves with respect to the Borrowing Base which Agents recommend be
effective commencing on such Determination Date, and (ii) Administrative Agent
shall notify each Lender of the amount of such recommended Borrowing Base. If
Required Lenders fail to promptly approve such recommended Borrowing Base,
Agents shall propose one or more alternative Borrowing Bases and shall consult
with Lenders regarding the proposed Borrowing Base until such time as Required
Lenders approve a Borrowing Base proposed by Agents. Promptly upon approval by
Required Lenders of the Borrowing Base to become effective on a Determination
Date, Administrative Agent shall provide written notice of the amount of such
Borrowing Base to Borrower which shall become effective on the date specified in
such notice (which shall be no sooner than the date such notice is sent). In the
event Required Lenders fail to approve a Borrowing Base to be effective on any
applicable Determination Date, the Borrowing Base in effect prior to such
Determination Date shall remain in effect until such time as a new Borrowing
Base is redetermined in accordance with this SECTION 4.01(B).

         4.02. PERIODIC REDETERMINATION. The Borrowing Base shall be
redetermined semi-annually on November 1 and May 1, commencing November 1, 1997,
or on such date promptly following each such date as may be required to
redetermine the Borrowing Base in accordance with the procedures set forth in
SECTION 4.01(B).

         4.03. SPECIAL REDETERMINATION REQUESTED BY BORROWER. In addition to
Periodic Determinations required herein and Special Determinations requested by
Required Lenders in accordance with SECTION 4.04, Borrower may request up to two
Special Determinations of the Borrowing Base pursuant to this SECTION 4.03 in
each calendar year; PROVIDED, THAT, one of such requests must be in connection
with a request for an increase in the Borrowing Base to finance the acquisition
by Borrower (or one of its Subsidiaries) of additional oil and gas properties
("ADDITIONAL PROPERTIES"). Together with any Request for Determination delivered
by Borrower to Lenders under this SECTION 4.03, Borrower shall deliver to
Lenders a Reserve Report prepared as of a date not more than 30 days prior to
the date of such Request for Determination. At Borrower's option, such Reserve
Report may only apply to (a) the Additional Properties which are the subject of
such request, or (b) those existing properties which Borrower believes support
an increase in the Borrowing Base as a result of the completion of a successful
drilling and development program or other factors.

         4.04. SPECIAL DETERMINATIONS REQUESTED BY REQUIRED LENDERS. In addition
to Periodic Determinations required herein and Special Determinations requested
by Borrower in accordance with SECTION 4.03, Required Lenders may request (a) a
Special Determination in connection with any issuance by Borrower or any of its
Subsidiaries of Subordinated Debt (other than in accordance with the Approved



                            CREDIT AGREEMENT-Page 25
<PAGE>   26



Notes Offering) or preferred stock, and (b) from and after the earlier to occur
of the Trigger Event or November 1, 1997, two Special Determinations in each
calendar year in addition to each Special Determination allowed under SECTION
4.04(A); PROVIDED, THAT, one such Special Determination requested pursuant to
this clause (b) shall be based on a determination by Required Lenders, in their
sole discretion that either (i) there has been a material decrease in the
Present Value of Borrower's Oil and Gas Properties, or (ii) an event has
occurred which has had, or which is reasonably expected to have, a Material
Adverse Effect. In the event Required Lenders request a Special Determination
pursuant to this SECTION 4.04, they may, at their option, suspend the next
Periodic Determination.

         4.05. INITIAL BORROWING BASE. Subject to the rights of Borrower and
Required Lenders to request an earlier Special Determination pursuant to SECTION
4.03 or 4.04 above, the Borrowing Base in effect under this Agreement (a) for
the period from the Closing Date until August 13, 1997, shall be $400,000,000,
and (b) from and after August 13, 1997, until the Periodic Determination
scheduled to occur on or around November 1, 1997, shall be $325,000,000, unless
the reduction to such amount is waived by all Lenders; PROVIDED, THAT, the
Borrowing Base in effect under clause (a) of this SECTION 4.05 shall reduce
simultaneously with the receipt by Borrower or any of its Subsidiaries on or
before August 13, 1997, of Net Cash Proceeds resulting from the Approved Notes
Offering, the Common Stock Offering, or any sale or disposition by Borrower or
any of its Subsidiaries of any asset owned by them (other than the sale of
Hydrocarbons produced in the ordinary course of business). Any reduction of the
Borrowing Base pursuant to the foregoing proviso shall be effective
simultaneously with the receipt of such Net Cash Proceeds and shall be in an
amount equal to the lesser of (i) the amount of such Net Cash Proceeds, or (ii)
the amount necessary to reduce the Borrowing Base to $325,000,000.
Notwithstanding the preceding sentence, if the aggregate principal amount of

claim, citation, or notice by any Governmental Authority or any person or entity
with respect to (1) air emissions; (2) release; (3) noise emissions; (4) solid
or liquid waste disposal; (5) the use, generation, storage, transportation, or
disposal of waste ("TREATMENT"); or (6) other environmental, health, or safety
matters affecting Borrower or any Subsidiary of Borrower or its business,
operations, assets, equipment, property, leaseholds, or other facilities.

                  (o) TITLES. Each of Borrower and its Subsidiaries has good and
defensible title to all material assets purported to be owned by it subject only
to Permitted Encumbrances, including, after giving effect to the Cometra
Acquisition, all of the Cometra Assets. Without limiting the foregoing, after
giving effect to the Cometra Acquisition, with the exception of oil and gas
properties which are clearly identified as being owned by Persons other than the
Loan Parties, the Loan Parties have good and defensible title to all material
oil and gas properties which are the subject of the most recent Reserve Report
provided to Lenders (or, until superseded, the oil and gas properties which are
the subject of the Initial Reserve Report and the Cometra Reserve Report), and
the Mortgages establish first and prior Liens on the properties and interests
intended to be covered thereby subject only to Permitted Encumbrances.

                  (p) RESERVE REPORTS. The Initial Reserve Report and the
Cometra Reserve Report accurately reflect, and all Reserve Reports hereafter
delivered pursuant to this Agreement will reflect, in all material respects, the
ownership interests of Borrower and its Subsidiaries (in the case of the Cometra
Reserve Report, after giving effect to the Cometra Acquisition) in the oil and
gas properties referred to therein (including all material before and after
payout calculations).

                  (q) INTELLECTUAL PROPERTY. Each Loan Party owns, or is
licensed to use, all trademarks, tradenames, copyrights, technology, know how,
and processes necessary for the conduct of its business as currently conducted
except for those the failure to own or license which could not reasonably be
expected to have a Material Adverse Effect (the "INTELLECTUAL PROPERTY"). No
claim has been asserted 



                   ASSIGNMENT AND ASSUMPTION AGREEMENT-Page 33
<PAGE>   34



and is pending by any Person challenging or questioning the use of any
Intellectual Property or the validity or effectiveness of any Intellectual
Property, nor does any Loan Party know of any valid basis for any such claim,
except claims that, in the aggregate, could not reasonably be expected to have a
Material Adverse Effect. The use of Intellectual Property by a Loan Party does
not infringe on the rights of any Person, except for claims and infringements
that, in the aggregate, could not reasonably be expected to have a Material
Adverse Effect.

                  (r) NO BURDENSOME RESTRICTIONS. No applicable requirement of
law or contractual obligation of any Loan Party could reasonably be expected to
have a Material Adverse Effect.

                  (s) TAXES. Each Loan Party has filed all material tax returns
which to the knowledge of the Loan Party are required to be filed by it and has
paid or caused to be paid all material assessments, fees, and other governmental
charges levied upon it or upon any of its property or income which are due and
payable, except such taxes, assessments, fees, and other governmental charges,
if any, as are being diligently contested in good faith and by appropriate
proceedings and with respect to which there have been established adequate
reserves on the books of the Loan Party in accordance with GAAP. No tax lien has
been filed with respect to any material taxes or material assessments, fees, or
other governmental charges.

                  (t) FEDERAL REGULATIONS. No part of the proceeds of any Loan
will be used for "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation G or Regulation
U of the Board of Governors of the Federal Reserve System as now and from time
to time hereafter in effect. If requested by any Lender or Administrative Agent,
Borrower will furnish Administrative Agent and each Lender a statement to the
foregoing effect in conformity with the requirements of FR Form G-1 or FR Form
U-1 referred to in Regulation G or Regulation U, as the case may be.

                  (u) INVESTMENT COMPANY ACT; OTHER REGULATIONS. No Loan Party
is an "investment company", or a company "controlled" by an "investment
company", within the meaning of the Investment Company Act of 1940, as amended.
No Loan Party is subject to regulation under any Federal or State statute or
regulation (other than Regulation X of the Board of Governors of the Federal
Reserve System) which limits its ability to incur Indebtedness under this
Agreement or the other Loan Documents.

         7.02. AFFIRMATIVE COVENANTS. Borrower hereby agrees that, so long as
the Total Commitment remains in effect, any Loan, Note, or Letter of Credit
remains outstanding and unpaid, or any amount is owing to any Lender or any

                   ASSIGNMENT AND ASSUMPTION AGREEMENT-Page 35
<PAGE>   36




                  (h) DEPOSITORY ACCOUNTS. Maintain its primary depository
accounts at one or more of Lenders (Borrower acknowledges that this requirement
is a legitimate and reasonable measure to preserve and protect Lenders' first
priority Liens in all property intended as Security for the Obligations under
the Loan Documents).

                  (i) NOTICE OF DEFAULT AND LITIGATION. Give Lenders prompt
notice in writing of the occurrence or existence of a Default, an Event of
Default, any litigation or proceeding or other event affecting Borrower or any
of its Subsidiaries that could reasonably be expected to have a Material Adverse
Effect.

                  (j) FURTHER ASSURANCES. Borrower will and will cause each
Subsidiary to cure promptly any defects in the creation and issuance of the
Notes and the execution and delivery of the Security Documents and this
Agreement. Borrower at its expense will and will cause each Subsidiary to
promptly execute and deliver to Administrative Agent upon request all such other
documents, agreements, and instruments to comply with or accomplish the
covenants and agreements of Borrower or any Subsidiary, as the case may be, in
the Security Documents and this Agreement, or to further evidence and more fully
describe the collateral intended as security for the Obligations, or to correct
any omissions in the Security Documents, or to state more fully the security
obligations set out herein or in any of the Security Documents, or to perfect,
protect, or preserve any Liens created pursuant to any of the Security
Documents, or to make any recordings, to file any notices or obtain any
consents, all as may be necessary or appropriate in connection therewith.

                  (k) MAINTENANCE AND OPERATION OF PROPERTY. To the extent that
the failure to comply could have a Material Adverse Effect on the financial
condition or operations of Borrower or its Subsidiaries and consistent with the
standards of a reasonably prudent operator:

                           (1) Maintain, develop, and operate Borrower's Oil and
Gas Properties in a good and workmanlike manner, and observe and comply with all
of the terms and provisions, express or implied, of all oil and gas leases
relating to the properties so long as the oil and gas leases are capable of
producing hydrocarbons and accompanying elements in paying quantities;

                           (2) Comply in all material respects with all
contracts and agreements applicable to or relating to Borrower's Oil and Gas

operating equipment used with respect to Borrower's Oil and Gas Properties in
proper repair, working order and condition, and make all necessary or
appropriate repairs, renewals, replacements, additions and improvements thereto
so that the efficiency of the operating equipment shall at all times be properly
preserved and maintained, provided that no item of operating equipment need be
so repaired, renewed, replaced, added to or improved, if Borrower or its
Subsidiary shall in good faith determine that the action is not necessary or
desirable for its continued efficient and profitable operation of business.

                           (4) With respect to Borrower's Oil and Gas Properties
which are operated by operators other than Borrower or a Subsidiary, seek to
enforce the operators' contractual obligations to maintain, develop, and operate
the oil and gas properties subject to the applicable operating agreements.

                  (l) ERISA. As soon as possible, and in any event within 30
days after Borrower knows or has reason to know that any circumstances exist
that constitute grounds entitling the PBGC to institute proceedings to terminate
a Plan subject to ERISA with respect to Borrower or any Commonly Controlled
Entity, and promptly but in any event within two Business Days of receipt by
Borrower or any Commonly Controlled Entity of notice that the PBGC intends to
terminate a Plan or appoint a trustee to administer the same, and promptly but
in any event within five Business Days of the receipt of notice concerning the
imposition of withdrawal liability with respect to Borrower or any Commonly
Controlled Entity, Borrower shall deliver to each Lender a certificate of the
chief financial officer of Borrower setting forth all relevant details and the
action which Borrower proposes to take with respect thereto.

<PAGE>   37




                  (m) ENVIRONMENTAL MATTERS. To the extent necessary to avoid a

other party; notify Administrative Agent immediately of any release from or
affecting its properties; immediately contain and remove the same, in compliance
with all applicable laws; promptly pay any fine or penalty assessed in
connection therewith; permit Administrative Agent to inspect the premises, to
conduct tests thereon, and to inspect all books, correspondence, and records
pertaining thereto; and at Administrative Agent's request, and at Borrower's
expense, provide a report of a qualified environmental engineer, satisfactory in
scope, form, and content to Administrative Agent, and all other and further
assurances reasonably satisfactory to Administrative Agent that the condition
has been corrected.

                  (n) ENVIRONMENTAL INDEMNITY. NOTWITHSTANDING ANY OTHER
LIMITATION OF LIABILITY IN THIS OR ANY OTHER AGREEMENT OR INSTRUMENT BETWEEN
BORROWER OR A SUBSIDIARY AND LENDERS OR AGENTS, BORROWER PROMISES THAT IT WILL
INDEMNIFY, DEFEND, SAVE, AND HOLD HARMLESS EACH LENDER AND EACH AGENT AND
AGENT'S AND EACH LENDER'S AFFILIATES, OFFICERS, DIRECTORS, SHAREHOLDERS,
EMPLOYEES, AGENTS, ATTORNEYS, PARTNERS, AND THEIR RESPECTIVE HEIRS, SUCCESSORS,

LIABILITIES, LOSSES, COSTS, AND EXPENSES (INCLUDING, WITHOUT LIMITATION,
REASONABLE ATTORNEY'S FEES AND EXPENSES, COURT COSTS, ADMINISTRATIVE COSTS, AND
COSTS OF APPEALS), INCURRED BY OR ASSERTED AGAINST INDEMNIFIED PARTIES BY REASON
OR ARISING OUT OF THE TREATMENT OR RELEASE OF ANY WASTE IN, ON, OR AFFECTING OIL
AND GAS PROPERTIES OF BORROWER OR ITS SUBSIDIARIES, WHETHER OR NOT CAUSED BY
BORROWER OR ANY OF ITS SUBSIDIARIES, OR THE VIOLATION OF ANY ENVIRONMENTAL LAWS,
EXCEPT TO THE EXTENT CAUSED BY THE GROSS NEGLIGENCE OR WILFUL MISCONDUCT OF ANY
INDEMNIFIED PARTY. NOTWITHSTANDING ANYTHING IN THE LOAN DOCUMENTS TO THE
CONTRARY, THE UNDERTAKINGS OF BORROWER IN THIS PARAGRAPH SHALL SURVIVE THE
EXPIRATION OR TERMINATION OF THIS AGREEMENT REGARDLESS OF THE MEANS OF
EXPIRATION OR TERMINATION ; PROVIDED, HOWEVER, NO INDEMNITY SHALL BE AFFORDED
UNDER THIS SECTION 7.02(N) IN RESPECT OF ANY PROPERTY FOR ANY OCCURRENCE ARISING
FROM THE ACTS OR OMISSIONS OF ADMINISTRATIVE AGENT OR ANY LENDER DURING THE
PERIOD AFTER WHICH SUCH PERSON, ITS SUCCESSORS OR ASSIGNS, SHALL HAVE OBTAINED
POSSESSION OF SUCH PROPERTY (WHETHER BY FORECLOSURE OR DEED IN LIEU OF
FORECLOSURE, AS MORTGAGEE-IN-POSSESSION OR OTHERWISE). SPECIFICALLY, THE
INDEMNIFICATION IN THIS PARAGRAPH SHALL RUN FROM THE NOTICE COMMUNICATED TO
ADMINISTRATIVE AGENT OF ANY TREATMENT OR RELEASE OF WASTE OR OTHER ENVIRONMENTAL
CONDITION COVERED BY THIS AGREEMENT.

                  (o) OTHER INDEMNITY. BORROWER AGREES TO INDEMNIFY THE
INDEMNIFIED PARTIES AND HOLD THEM HARMLESS FROM AND AGAINST ANY AND ALL
LIABILITIES, LOSSES, DAMAGES, COSTS AND EXPENSES OF ANY KIND (INCLUDING, WITHOUT
LIMITATION, THE REASONABLE FEES AND DISBURSEMENTS OF COUNSEL FOR EACH
INDEMNIFIED PARTY IN CONNECTION WITH ANY INVESTIGATIVE, ADMINISTRATIVE OR
JUDICIAL PROCEEDING, WHETHER OR NOT THE INDEMNIFIED PARTIES SHALL BE DESIGNATED
A PARTY THERETO) WHICH MAY BE INCURRED BY ANY INDEMNIFIED PARTY, RELATING TO OR
ARISING OUT OF THIS AGREEMENT OR ANY ACTUAL OR PROPOSED USE OF PROCEEDS OF LOANS
HEREUNDER, INCLUDING AN INDEMNIFIED PARTY'S NEGLIGENCE; PROVIDED THAT
INDEMNIFIED PARTIES SHALL NOT BE INDEMNIFIED HEREUNDER FOR THEIR OWN GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT.

         8.02. REMEDIES. (a) Upon the occurrence of an Event of Default, and at
any time thereafter, Administrative Agent shall at the request of, or may, with

and payable, whereupon the Notes, all interest, and all other amounts shall
become and be immediately due and payable, without presentment, demand, protest,
notice of intent to accelerate, notice of acceleration, or further notice of any
kind, all of which are hereby expressly waived by Borrower, and (3) exercise all
of their rights and remedies under the Loan Documents; PROVIDED THAT in the case
of the Events of Default specified in SECTION 8.01(G) or (H), without any notice
to Borrower or any other act by Administrative Agent or Lenders, the Commitments
shall thereupon terminate and the Notes (together with accrued interest thereon)
shall become immediately due and payable.

                  (b) Upon the occurrence and during the continuance of any
Event of Default, each Lender is hereby authorized at any time and from time to
time, without notice to Borrower (any notice being expressly waived by
Borrower), to set off and apply any and all deposits (general or special, time
or demand, provisional or final), excluding those held in Special Accounts, at
any time held and other indebtedness at any time owing by that Lender to or for
the credit or the account of Borrower against any and all of the Obligations of
Borrower now or hereafter existing under this Agreement or any Note held by 


                   ASSIGNMENT AND ASSUMPTION AGREEMENT-Page 42
<PAGE>   43




that Lender or any other Loan Document, irrespective of whether or not
Administrative Agent or that Lender shall have made any demand under this
Agreement or the Note or such other Loan Document and although the obligations
may be unmatured. Each Lender agrees promptly to notify Borrower (with a copy of
Administrative Agent) after any set off and application, provided that the
failure to give the notice shall not affect the validity of the set off and
application. The rights of each Lender under this SECTION 8.02(B) are in
addition to the other rights and remedies (including, without limitation, other
rights of set off) which each Lender may have.

                  (c) Each Lender agrees that if it shall, by exercising any
right of setoff or counterclaim or otherwise, receive payment after the
occurrence and during the continuance of an Event of Default of a proportion of
the aggregate amount of principal and interest due with respect to any Loan
which is greater than the proportion received by any other Lender in respect of
such Loan, Lender receiving such proportionately greater payment shall purchase
such participations in the interests in such Loan held by the other Lenders, and
such other adjustments shall be made, as may be required so that all such
payments of principal and interest with respect to each Loan held by Lenders
shall be shared by Lenders ratably in accordance with their respective
Commitment Percentages; PROVIDED, THAT, nothing in this SECTION 8.03(C) shall
impair the right of any Lender to exercise any right of setoff or counterclaim
it may have and to apply the amount subject to such exercise to the payment of
indebtedness of Borrower other than its indebtedness under the Loans. Borrower
agrees, to the fullest extent it may effectively do so under applicable law,
that Lenders may exercise rights of setoff or counterclaim and other rights with
respect to such participation as fully as if such holder of a participation were
a direct creditor of Borrower in the amount of such participation.

for its or that Person's own gross negligence or willful misconduct) or (ii)
responsible in any manner to any Lender for any recitals, statements,
representations or warranties made by any Loan Party or any officer thereof
contained in this Agreement or any other Loan Document or in any certificate,

by Agents under or in connection with, this Agreement or any other Loan Document
or for the value, validity, effectiveness, genuineness, enforceability or

not be under any obligation to any Lender to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of any Loan Party.

         9.04. RELIANCE BY AGENTS. Agents shall be entitled to rely, and shall

<PAGE>   44

genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel (including, without

         9.05. NOTICE OF DEFAULT. No Agent shall be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless
such Agent has received notice from a Lender or Borrower referring to this

         9.06. NON-RELIANCE ON AGENTS AND OTHER LENDERS. Each Lender expressly
acknowledges that neither Agents nor any of their officers, directors,
employees, agents, attorneys-in-fact or Affiliates has made any representations
or warranties to it and that no act by Agents hereafter taken, including any
review of the affairs of any Loan Party, shall be deemed to constitute any
representation or warranty by Agents to any Lender. Each Lender represents to
Agents that it has, independently and without reliance upon Agents or any other
Lender, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of each
Loan Party and made its own decision to make its extensions of credit hereunder
and enter into this Agreement. Each Lender also represents that it will,
independently and without reliance upon Agents or any other Lender, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of each
Loan Party. Except for notices, reports, and other documents expressly required
to be furnished to Lenders by Administrative Agent hereunder, no Agent shall
have any duty or responsibility to provide any Lender with any credit or other

employees, agents, attorneys-in-fact or Affiliates.

         9.07. INDEMNIFICATION. Lenders agree to indemnify each Agent in its
capacity as such (to the extent not reimbursed by Borrower and without limiting
the obligation of Borrower to do so), ratably according to their respective
Commitment Percentages in effect on the date on which indemnification is sought,
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind whatsoever which may at any time (including, without limitation, at any
time following the payment of the Obligations) be imposed on, incurred by or
asserted against any Agent in any way relating to or arising out of, the Total
Commitment, this Agreement, any of the other Loan Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by each Agent
under or in connection with any of the foregoing; provided that no Lender shall
be liable for the payment of any portion of the liabilities, obligations,

Obligations and all other amounts payable hereunder.



                   ASSIGNMENT AND ASSUMPTION AGREEMENT-Page 44
<PAGE>   45



         9.08. EACH AGENT IN ITS INDIVIDUAL CAPACITY. Each Agent and its
Affiliates may make loans to, accept deposits from, and generally engage in any
kind of business with any Loan Party as though such Agent were not an Agent
hereunder and under the other Loan Documents. With respect to the extensions of
credit made by it, each Agent shall have the same rights and powers under this
Agreement and the other Loan Documents as any Lender and may exercise the same
as though it were not an Agent, and the terms "Lender" and "Lenders" shall
include each Agent in its individual capacity.

         9.09. SUCCESSOR AGENT. Each Agent may resign as Agent upon written
notice to Lenders and the appointment of a Successor Agent as set out in the
following sentence. If an Agent shall resign as Agent under this Agreement and
the other Loan Documents, then Required Lenders shall appoint from among Lenders
a successor agent for Lenders, which successor agent, with the consent of
Borrower (the consent not to be unreasonably withheld or delayed), shall succeed
to the rights, powers and duties of such Agent hereunder. Effective upon the
appointment and approval, the term "Agent" shall mean the successor agent
(serving in the capacity of the predecessor Agent), and the former Agent's
rights, powers and duties as Agent shall be terminated, without any other or
further act or deed on the part of the former Agent or any of the parties to
this Agreement or any holders of the Loans. After any retiring Agent's
resignation as Agent, the provisions of this Article 9 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Agreement and the other Loan Documents.

         9.10. ISSUING LENDER. The provisions of this Article 9 applicable to an
Agent shall apply to the Issuing Lender in the performance of its duties under
the Loan Documents, allowing for the appropriate changes that must be made.

ARTICLE 10 - PROTECTION OF YIELD; CHANGE IN LAWS.
- -------------------------------------------------

         10.01. RISK-BASED CAPITAL. In the event any Lender determines that (a)
compliance with any judicial, administrative, or other governmental
interpretation of any law or regulation adopted or made after the date hereof,
or (b) compliance by such Lender or any corporation controlling such Lender with
any guideline or request from any central bank or other Governmental Authority
(whether or not having the force of law) adopted or made after the date hereof
has the effect of requiring an increase in the amount of capital required or
expected to be maintained by such Lender or any corporation controlling the
Lender, and such Lender determines that the increase is based upon its
obligations hereunder, Borrower shall pay to Administrative Agent, for the
account of the applicable Lender, the additional amount as shall be certified by
that Lender to be the amount allocable to such Lender's obligations to Borrower
hereunder. Such Lender will promptly notify Borrower (with a copy to
Administrative Agent) of any event occurring after the date of this Agreement
that will entitle that Lender to compensation pursuant to this SECTION 10.01 as
promptly as practicable, and in any event within 90 days after it obtains
knowledge thereof and determines to request the compensation.

                  Borrower's obligations under this Section 10.01 shall be
subject to delivery to Borrower by any Lender claiming compensation under this
Section 10.01 of a certificate setting forth in reasonable detail the additional
amount or amounts to be paid to it hereunder and certifying that it is generally
charging such costs to other similarity situated borrowers under similar credit
facilities.

                  Determinations by a Lender for purposes of this SECTION 10.01
of the effect of any increase in the amount of capital required to be maintained
by such Lender and of the amount allocable to that Lender's obligations to
Borrower hereunder shall be conclusive, absent manifest error.

         10.02. BASIS FOR DETERMINING INTEREST RATE APPLICABLE TO EURODOLLAR
LOANS INADEQUATE. If on or prior to the first day of any Interest Period:

                  (a) Administrative Agent is advised that deposits in dollars
(in the applicable amounts) are not being offered to Lenders in the interbank
eurocurrency market for the Interest Period, or

                  (b) Administrative Agent determines that the Eurodollar Rate
as determined by it will not adequately and fairly reflect the cost to Lenders
of funding a Eurodollar Loan for the Interest Period; or


                   ASSIGNMENT AND ASSUMPTION AGREEMENT-Page 45
<PAGE>   46



                  (c) Adequate means do not exist in the interbank eurocurrency
market to determine the Eurodollar Rate; the obligation of Lenders to make
Eurodollar Loans shall be suspended until Administrative Agent notifies Borrower
that the circumstances giving rise to the suspension no longer exist. Unless
Borrower notifies Administrative Agent at least two Business Days before the
date of any Eurodollar Loan previously requested that it elects not to borrow on
that date, the Loan shall instead be made as a ABR Loan.

         10.03. ILLEGALITY OF EURODOLLAR LOANS. (a) If, after the date of this
Agreement, the adoption of any applicable law, rule or regulation, or any change
therein, or any change in the interpretation or administration thereof by any
Governmental Authority, central Bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender (or its
Lending Office) with any request or directive (whether or not having the force
of law) of any the authority, central Bank, or comparable agency shall make it
unlawful or impossible for that Lender (or its Lending Office) to make, maintain
or fund its Eurodollar Loans, the obligation of such Lender to make Eurodollar
Loans shall be suspended. If any Lender determines that it may not lawfully
continue to maintain and fund any of its outstanding Eurodollar Loans to
maturity, Borrower shall immediately convert the principal amount of each
Eurodollar Loan to an ABR Loan of an equal principal amount from such Lender.

                  (b) No Lender shall be required to make a Loan hereunder if
the making of the Loan would be in violation of any law applicable to such
Lender.

         10.04. INCREASED COST OF EURODOLLAR LOANS. If after the date hereof,
the adoption of any applicable law, rule or regulation, or any change therein,
or any change in the interpretation or administration hereof by any Governmental
Authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender with any request or
directive (whether or not having the force of law) of any that authority,
central bank, or comparable agency:

                  (a) shall subject such Lender to any tax, duty or other charge
with respect to its Eurodollar Loans or its obligation to make Eurodollar Loans
or shall change the basis of taxation of payments to a Lender of the principal
of or interest on its Eurodollar Loans or any other amounts due under this
Agreement in respect of its Eurodollar Loans or its obligation to make
Eurodollar Loans (except for changes in the rate of tax on the overall net
income of a Lender imposed by the jurisdiction in which such Lender's Lending
Office is located); or

                  (b) shall impose, modify or deem applicable any reserve,
special deposit or similar requirement [including, without limitation, any
requirement imposed by the Board of Governors of the Federal Reserve System (but
excluding with respect to any Eurodollar Loan any requirement included in an
applicable Eurodollar Reserve Percentage)] against assets of, deposits with or
for the account of or credit extended by such Lender or shall impose on such
Lender or the eurodollar interbank market any other condition affecting the
Eurodollar Loans, any Note or such Lender's obligation to make Eurodollar Loans;

and the result of any of the foregoing is to increase the cost to such Lender of
making or maintaining any Eurodollar Loan, or to reduce the amount of any sum
received or receivable by that Lender under this Agreement or under the Note
with respect thereto, by an amount deemed by the Lender to be material, then,
within 10 days after demand by Administrative Agent, Borrower shall pay to that
Lender the additional amount or amounts as will compensate that Lender for the
increased cost or reduction. Each Lender will promptly notify Borrower and
Administrative Agent of any event of which it has knowledge, occurring after the
date hereof, which will entitle such Lender to compensation pursuant to this
SECTION 10.04 and will designate a different Lending Office if the designation
will avoid the need for, or reduce the amount of, such compensation and will
not, in the reasonable judgment of that Lender, be otherwise disadvantageous to
the Lender. Borrower's obligations under this SECTION 10.04 shall be subject to
delivery to Borrower of a certificate by any Lender claiming compensation under
this SECTION 10.04, setting forth in reasonable detail the additional amount or
amounts to be paid to it hereunder and certifying that it is generally charging
such costs to other similarly situated borrowers under similar credit 



                   ASSIGNMENT AND ASSUMPTION AGREEMENT-Page 46
<PAGE>   47


facilities shall be delivered to Borrower and shall be conclusive in the absence
of manifest error. In determining the amount, each Lender must use reasonable
averaging and attribution methods.

         10.05. ALTERNATIVE LOANS SUBSTITUTED FOR AFFECTED EURODOLLAR LOANS. If
(a) the obligation of any Lender to make Eurodollar Loans has been suspended
pursuant to SECTION 10.03 or (B) such Lender has demanded compensation under
SECTION 10.04, and Borrower shall, by at least five Business Days prior notice
to such Lender, have elected that the provisions of this SECTION 10.05 shall
apply, then, unless and until such Lender notifies Borrower that the
circumstances giving rise to the suspension or demand for compensation no longer
apply:

                           (i) all Loans which would otherwise be made by such
Lender as Eurodollar Loans shall be made instead as ABR Loans, and

                           (ii) after each of its Eurodollar Loans has been
repaid, all payments of principal which would otherwise be applied to repay the
Eurodollar Loans shall be applied to repay its ABR Loans.

         10.06. FUNDING LOSS INDEMNIFICATION. Upon notice to Borrower from a
Lender (with a copy to Administrative Agent), Borrower shall pay to
Administrative Agent, within five days after notice from a Lender, for the
ratable benefit of each Lender, the amount or amounts sufficient to compensate
them for any actual loss, cost, or expense (excluding loss of anticipated
profits) incurred as a result of:

                  (a) Any payment of a Eurodollar Loan on a date other than the
last day of the Interest Period for the Loan including, but not limited to,
acceleration of the Loans by Administrative Agent pursuant to this Agreement, or

                  (b) Any failure by Borrower to borrow or convert, as the case
may be, a Eurodollar Loan on the date for borrowing or conversion, as the case
may be, specified in the relevant notice under SECTION 2.02 or 2.07, as the case
may be.

Each Lender shall determine the amount of compensation and will provide Borrower
with the basis for its determination. Each Lender's determination shall be
conclusive, absent manifest error.

         10.07. TAXES. All amounts payable by Borrower under the Loan Documents
(whether principal, interest, fees, expenses, or otherwise) to or for the
account of each Lender shall be paid in full, free of any deductions or
withholdings for or on account of any Taxes. If Borrower is prohibited by law
from paying the amount free of any deductions and withholdings, then (at the
same time and in the same manner that the original amount is otherwise due under
the Loan Documents), Borrower shall pay to or for the account of such Lender
such additional amount as may be necessary in order that the actual amount
received by such Lender after deduction and/or withholding (and after payment of
any additional Taxes due as a consequence of the payment of the additional
amount, and so on) will equal the amount such Lender would have received if the
deduction or withholding were not made.

         10.08. DISCRETION OF LENDERS AS TO MANNER OF FUNDING. Notwithstanding
any provisions of this Agreement to the contrary, each Lender shall be entitled
to fund and maintain its funding of all or any part of its Loans in any manner
it sees fit, it being understood, however, that for the purposes of this
Agreement all determinations hereunder shall be made as if such Lender had
actually funded and maintained each Eurodollar Loan during the Interest Period
for the Eurodollar Loan through the purchase of deposits having a maturity
corresponding to the last day of the Interest Period and bearing an interest
rate equal to the Eurodollar Rate for the Interest Period.

         10.09. LIMITATION ON ADDITIONAL AMOUNTS. Notwithstanding anything to
the contrary contained in SECTION 10.01, 10.04, and 10.07, neither Borrower nor
any Subsidiary of Borrower shall be required to pay to any Lender any increased
costs, Taxes, loss, expense, or liability, reduction in amounts received or
receivable or reduction in return on capital incurred more than 180 days prior
to the date that such Lender notifies Borrower of such Lender's intention to
claim any such compensation; provided that if the circumstances giving rise to
such claim have a retroactive effect, then such 180 day period shall be extended
to include the period of such retroactive effect.



                   ASSIGNMENT AND ASSUMPTION AGREEMENT-Page 47
<PAGE>   48



         10.10. REPLACEMENT LENDERS. (a) If any Lender has notified Borrower and
Administrative Agent of its incurring additional costs under SECTIONS 10.01 or
10.04, or has required Borrower to make payments for Taxes under SECTION 10.07,
then Borrower may, unless such Lender has notified Borrower and Administrative
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
Administrative Agent) (the "TERMINATED LENDER") at any time upon five Business
Days prior written notice to the Terminated Lender and Administrative 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, 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 all Agents and become parties by executing an
assignment reasonably acceptable to all Agents (an "ASSIGNMENT"; and Lenders or
other banking institutions 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.

                  (c) The Notice of Termination shall include the name of the
Terminated Lender, the date the termination will occur (the "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 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 Loan (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 Note, 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 Note 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 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
12.08(B), and the Terminated Lender will have the rights and benefits of an
assignor under SECTION 12.08(B). To the extent not in conflict, the terms of
SECTION 12.08(B) shall supplement the provisions of this SECTION 10.10(D). For
each assignment made under this SECTION 10.10, the Replacement Lender shall pay
to Administrative Agent any processing fee provided for in SECTION 12.08(B).
Borrower shall pay any breakage costs as provided by SECTION 10.06, which occur
as a result of the operation of this SECTION 10.10.

         11.01 COMMITMENT FEES. On the first day of each January, April, July,

any earlier termination of the Commitments, Borrower shall pay to Administrative
Agent for the ratable benefit of each Lender, a commitment fee payable with
respect to the daily Unused Availability for the calendar quarter (or portion
thereof) ending on the day prior to the date such payment is due equal to (i)
 .25% per annum of the average daily Unused Availability for such calendar
quarter or portion thereof if the daily average Borrowing Base Usage during such
calendar quarter (or portion thereof) is less than 50% for the calendar quarter
ending on the date immediately preceding the date such commitment fee is
payable, (ii) .30% per annum of the average daily Unused Availability for such
calendar quarter or portion thereof if the average daily Borrowing Base Usage

the average daily Unused Availability for such calendar quarter or portion
thereof if the average daily Borrowing Base Usage during such calendar quarter

ending on the day immediately preceding the date such commitment fee is payable;
PROVIDED THAT, until the Trigger Event has occurred, each of the referenced
rates shall be increased by 0.05% prior to March 31, 1997, and by 0.10%
thereafter. The commitment fees payable pursuant to this SECTION 11.01 shall be
calculated on the basis of the actual number of days elapsed assuming a calendar
year of 360 days.

         11.02. AGENCY FEES. Borrower shall pay to each Agent and its Affiliates
those fees and other amounts as Borrower shall be required to pay to each Agent
and its Affiliates from time to time pursuant to any separate agreement between
Borrower and that Agent or any of its Affiliates setting forth the compensation
to be paid to such Agent and its Affiliates in consideration for acting as Agent
hereunder and for providing other services in connection with the credit
facilitations provided pursuant hereto. These fees and other amounts shall be
retained by the applicable Agent and its Affiliates, and no Lender (other than
the applicable Agents) shall have any interest therein.

         11.03. LETTER OF CREDIT FEES. Borrower shall pay to Administrative
Agent, for the ratable benefit of each Lender, and to the Issuing Lender, as

ratable benefit of each Lender, those fees and other amounts as Borrower shall
be required to pay to each Lender from time to time pursuant to any separate
agreement between Borrower and Administrative Agent, for the ratable benefit of
each Lender, setting forth the compensation to be paid to Lenders in
consideration for participating in the credit facilitations provided pursuant
hereto.

ARTICLE 12 - GENERAL PROVISIONS.
- --------------------------------

         12.01. EXPENSES. Borrower shall pay (i) all reasonable out-of-pocket
expenses of Syndication Agent associated with the syndication of the Loans, (ii)
all reasonable out-of-pocket expenses of Syndication Agent, including reasonable
fees, disbursements and other charges of counsel for Syndication Agent, in
connection with the preparation of this Agreement and the other Loan Documents
and, if appropriate, the recordation of the Loan Documents, (iii) all reasonable
out-of-pocket expenses of Administrative Agent, including reasonable fees,
disbursements, and other charges of counsel for Administrative Agent, in
connection with the preparation of any waiver or consent under this Agreement or
any amendment hereof or any default or alleged default hereunder, (iv) all
reasonable out-of-pocket expenses of preparing, obtaining, and furnishing to any
Agent or any Lender any statements, opinions, certificates, schedules,
documents, insurance policies, and all other items required to furnished to any
Agent or any Lender pursuant to this Agreement or any request made pursuant to
this Agreement or any other Loan Document, and (v) if an Event of Default
occurs, all out-of-pocket expenses incurred by Administrative Agent or any
Lender, including the fees, disbursements and other charges of counsel in
connection with such Event of Default and collection and other enforcement
proceedings resulting therefrom, fees of auditors and consultants incurred in
connection therewith and investigation expenses incurred by Administrative Agent
or any Lender in connection therewith.



                   ASSIGNMENT AND ASSUMPTION AGREEMENT-Page 49
<PAGE>   50



         12.02. NON-WAIVER. No act, delay, omission, or course of dealing will
be a waiver of any of a Lender's rights or remedies under this Agreement or
otherwise, and no waiver, change, or modification in whole or in part of this
Agreement, any Note, or any other agreement will be effective unless in a
writing signed by Borrower and Lenders. All rights and remedies of Lenders are
cumulative and may be exercised singly or concurrently. A waiver by Lenders of
any right or remedy on any occasion will not be a bar to the exercise of any
right or remedy on any subsequent occasion.

         12.03 . AMENDMENT AND WAIVERS. Any provision of this Agreement, the
Notes or the other Loan Documents may be amended or waived if, but only if such
amendment or waiver is in writing and is signed by Borrower and Majority Lenders
(and, if the rights or duties of Administrative Agent are affected thereby, by
Administrative Agent); PROVIDED THAT no amendment or waiver shall, unless signed
by all Lenders, (a) modify the voting percentages of Lenders, or (b) release a
guarantor or any part of the Collateral (other than as contemplated hereby); and
further provided that no amendment or waiver shall, unless signed by each Lender
directly affected thereby, (i) increase the Commitment of such Lender or subject
any Lender to any additional obligation, (ii) forgive any of the principal of or
reduce the rate of interest on any Loan or any fees hereunder, (iii) postpone
the date fixed for any payment of principal of or interest on any Loan or any
fees hereunder, or (iv) change a Lender's Commitment Percentage except as
otherwise provided for in this Agreement or of the aggregate unpaid principal
amount of the Notes, or the definitions of Majority Lenders and Required Lenders
or the number or percentage of Lenders required to take any action under this
SECTION 12.03 or any other provision of this Agreement.

         12.04. SURVIVAL. All representations, warranties, and covenants made by
Borrower herein or in any certificate or other instrument delivered by it or in
its behalf under the Loan Documents shall be considered to have been relied upon
by Lenders and shall survive the delivery to Lenders of the Loan Documents or
the extension of the Loans (or any part thereof), regardless of any
investigation made by or on behalf of Lenders.

         12.05. LIMITATION ON INTEREST. Regardless of any provision contained in
the Loan Documents, Lenders shall never be entitled to contract for, charge,
receive, collect, or apply, as interest on the Loans, any amount in excess of
the Maximum Lawful Rate, and in the event Lenders ever contract for, charge,
receive, collect or apply as interest any excess, the amount which would be
deemed excessive interest shall be deemed a partial prepayment of principal and
treated hereunder as such; and if the Loans are paid in full, any remaining
excess shall promptly be paid to Borrower. In determining whether or not the
interest paid or payable under any specific contingency exceeds the Maximum
Lawful Rate, Borrower and Lenders shall, to the extent permitted under
applicable law, (a) characterize any nonprincipal payment as an expense, fee or
premium rather than as interest, (b) exclude voluntary prepayments and the
effects thereof and (c) amortize, prorate, allocate and spread, in equal parts,
the total amount of the interest throughout the entire contemplated term of the
Notes, so that the interest rate is the Maximum Lawful Rate throughout the
entire term of the Notes; provided, however, that if the unpaid principal
balance thereof is paid and performed in full prior to the end of the full
contemplated term thereof, and if the interest contracted for, charged or
received for the actual period of existence thereof exceeds the Maximum Lawful
Rate, Lenders shall refund to Borrower or any Subsidiary, as appropriate, the
amount of the excess and, in that event, Lenders shall, to the fullest extent
permitted under applicable law, not be subject to any penalties provided by any
laws for contracting for, charging, taking, reserving or receiving interest in
excess of the Maximum Lawful Rate.

         12.06. INVALID PROVISIONS. If any provision of the Loan Documents is
held to be illegal, invalid, or unenforceable under present or future laws
effective during the term thereof, the provision shall be fully severable, the
Loan Documents shall be construed and enforced as if the illegal, invalid, or
unenforceable provision had never comprised a part thereof, and the remaining
provisions thereof shall remain in full force and effect and shall not be
affected by the illegal, invalid, or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of the illegal, invalid, or unenforceable
provision there shall be added automatically as a part of the Loan Documents a
provision as similar in terms to the illegal, invalid, or unenforceable
provision as may be possible and be legal, valid and enforceable.

         12.07. WAIVER OF CONSUMER CREDIT LAW. Pursuant to Article 15.10(b) of
Chapter 15, Subtitle 79, Revised Civil Statutes of Texas, 1925, as amended,
Borrower agrees that Chapter 15 shall not govern or in any manner apply to the
Loans.


                   ASSIGNMENT AND ASSUMPTION AGREEMENT-Page 50
<PAGE>   51



         12.08. SUCCESSORS AND ASSIGNS. (a) The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, except that Borrower may not assign or
otherwise transfer any of its rights under this Agreement.

                  (b) Each Lender may transfer or assign all or any part of its
interest in Loans and its interest herein to any of its Affiliates regardless of
the term of the transfer or assignment. Each Lender may transfer or assign all
or any part of its interest in Loans to any commercial bank which is a member of
the Federal Reserve System and has combined capital and surplus and undivided
profits of not less than $100,000,000. Notwithstanding the foregoing, no Lender
shall transfer or assign all or any part of its Loans under this Agreement to
any Person other than an Affiliate of such Lender without the prior written
approval of Borrower and Agents, the approval to not be unreasonably withheld;
PROVIDED, THAT, Borrower's consent will not be required if a Default or Event of
Default has occurred and is continuing. As to each assignment of Loans permitted
by this Agreement, Borrower releases the assigning Lender from its obligations
under this Agreement as to the portion of the Loans assigned.

                  (c) Any Lender may (subject to the provisions of this section,
in accordance with applicable law, in the ordinary course of its business, and
at any time) sell to one or more Persons participating interests in its portion
of the Obligations. The seller Lender remains a "Lender" under the Loan, the
participant does not become a "Lender" under the Loan Documents, and the selling
Lender's obligations under the Loan Documents remain unchanged. The selling
Lender remains solely responsible for the performance of its obligations and
remains the holder of its share of the outstanding Loan for all purposes under
the Loan Documents. Borrower and each Agent shall continue to deal solely and
directly with the selling Lender in connection with that Lender's rights and
obligations under the Loan Documents, and each Lender must retain the sole right
and responsibility to enforce due obligations of Borrower. Participants have no
rights under the Loan Documents except certain voting rights as provided below.
No Lender may sell any participating interest under which the participant has
any rights to approve any amendment, modification, or waiver of any Loan
Document except as to matters requiring the approval of all Lenders as set forth
in SECTION 12.03.

                  (d) Each Lender shall have the right to disclose any
information in its possession regarding Borrower or any Subsidiary, or regarding
the Collateral, to any transferee, participant, potential transferee, or
potential participant of any of the Loans or any part thereof; provided that
such Persons agree to be bound by the provisions of SECTION 12.16.

                  (e) Nothing herein shall prohibit a Lender from pledging or
assigning any Note to any Federal Reserve Bank in accordance with applicable
law.

         12.09. FOREIGN LENDERS, PARTICIPANTS, AND ASSIGNEES. Each Lender,
participant (by accepting a participation interest under this Agreement), and
assignee (by executing an assignment and assumption agreement in a form
acceptable to Agents) that is not organized under the laws of the United States
of America or one of its states (a) represents to Administrative Agent and
Borrower that (i) no Taxes assessed by any Governmental Authority in the United
States are required to be withheld by Administrative Agent or Borrower with
respect to any payments to be made to it in respect of the Obligations and (ii)
it has furnished to Administrative Agent and Borrower two duly completed copies
of either U. S. Internal Revenue Service Form 4224, Form 1006, Form W-8, or
other form acceptable to Administrative Agent that entitles it to exemption from
U.S. federal withholding Tax on all interest payments under the Loan Documents,
and (b) covenants to (i) provide Administrative Agent and Borrower a new Form
4224, Form 1001, Form W-8, or other form acceptable to Administrative Agent upon
the expiration or obsolescence of any previously delivered form according to
applicable laws and regulations, duly executed and completed by it, and (ii)
comply from time to time with all applicable laws and regulations with regard to
the withholding Tax exemption. If any of the foregoing is not true or the
applicable forms are not provided, then Borrower and Administrative Agent
(without duplication) may deduct and withhold from interest payments under the
Loan Documents any United States federal income Tax at the maximum rate under
the Code without reimbursement pursuant to SECTION 10.07.

         12.10. NOTICES. All notices, requests, or other communications required
or permitted to be given by this Agreement or any other Loan Documents must be
in writing (including by facsimile transmission)

Loans, payable or to be reimbursed to Lenders under the Credit Agreement or any

         1.2 OTHER DEFINITIONAL PROVISIONS. (a) The words "hereof," "herein,"
"hereto," and "hereunder" and words of similar import when used in this

unless otherwise specified.

                  (b) The meanings given to terms defined herein shall be
equally applicable to both the singular and plural forms of the terms.

ARTICLE 2 - GUARANTY
- --------------------

         2.1 GUARANTIES. (a) Each of the Guarantors hereby, jointly and
severally, unconditionally and irrevocably, guarantees to Administrative Agent,
for the ratable benefit of Lenders and their respective successors, indorsees,
transferees, and assigns, the prompt and complete payment and performance by
Borrower when due (whether at the stated maturity, by acceleration, or
otherwise) of the Guarantor Obligations.

                  (b) Anything herein or in any other Loan Document to the
contrary notwithstanding, the maximum liability of each Guarantor hereunder and
under the other Loan Documents shall in no event exceed the 


                           GUARANTY AGREEMENT-Page 2
<PAGE>   75



amount which can be guaranteed by the Guarantor under applicable federal and
state laws relating to the insolvency of debtors (after giving effect to the
right of contribution established in Section 2.2).

                  (c) Each Guarantor agrees that the Guarantor Obligations may
at any time and from time to time exceed the amount of the liability of the
Guarantor hereunder without impairing this guaranty or affecting the rights and
remedies of Administrative Agent or any Lender hereunder.

                  (d) This guaranty shall remain in full force and effect until
all the Guarantor Obligations and the obligations of each Guarantor under this
guaranty has been satisfied by payment in full in cash, no Letter of Credit is
outstanding and the Total Commitment is terminated, notwith-standing that from
time to time during the term of the Credit Agreement Borrower may be free from
any Borrower Obligations.

         2.2 RIGHT OF CONTRIBUTION. Each Guarantor hereby agrees that to the
extent that a Guarantor has paid more than its proportionate share of any
payment made hereunder, the Guarantor shall be entitled to seek and receive
contribution from and against any Guarantor hereunder which has not paid its
proportionate share of the payment. Each Guarantor's right of contribution shall
be subject to the terms and conditions of Section 2.3. The provisions of this
Section 2.2 shall in no respect limit the obligations and liabilities of any
Guarantor to Administrative Agent and Lenders, and each Guarantor shall remain
liable to Administrative Agent and Lenders for the full amount guaranteed by the
Guarantor hereunder.

         2.3 LIMITED SUBROGATION. Notwithstanding any payment made by any
Guarantor hereunder or any setoff or application of funds of any Guarantor by
Administrative Agent or any Lender, no Guarantor shall be entitled to be
subrogated to any of the rights of Administrative Agent or any Lender against
Borrower or any Guarantor or any collateral security or guaranty or right of
setoff held by Administrative Agent or any Lender for the payment of the
Guarantor Obligations, nor shall any Guarantor seek or be entitled to seek any
contribution or reimbursement from Borrower or any Guarantor in respect of
payments made by the Guarantor hereunder, until all amounts owing to
Administrative Agent and Lenders by Borrower on account of the Guarantor
Obligations are paid in full in cash, no Letter of Credit is outstanding, and
the Total Commitment is terminated. If any amount is paid to any Guarantor on
account of subrogation rights at any time when all of the Guarantor Obligations
have not have been paid in full, that amount shall be held by the Guarantor in
trust for Administrative Agent and Lenders, segregated from other funds of the
Guarantor, and shall, forthwith upon receipt by the Guarantor, be turned over to
Administrative Agent in the exact form received by the Guarantor (duly indorsed
by the Guarantor to Administrative Agent, if required), to be applied against
the Guarantor Obligations, whether matured or unmatured, in such order as
Administrative Agent may determine.

         2.4 AMENDMENTS WITH RESPECT TO THE GUARANTOR OBLIGATIONS. Each
Guarantor shall remain obligated hereunder notwithstanding that, without any
reservation of rights against any Guarantor and without notice to or further
assent by any Guarantor, any demand for payment of any of the Guarantor
Obligations made by Administrative Agent or any Lender may be rescinded by
Administrative Agent or the Lender and any of the Guarantor Obligations
continued, and the Guarantor Obligations, or the liability of any other Person
upon or for any part thereof, or any collateral security or guaranty therefor or
right of setoff with respect thereto, may, from time to time, in whole or in
part, be renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered, or released by Administrative Agent or any Lender, and the Credit
Agreement and the other Loan Documents and any other documents executed and
delivered in connection therewith may be amended, modified, supplemented, or
terminated, in whole or in part, as Administrative Agent (or Required Lenders,
as the case may be) may deem advisable from time to time, and any collateral
security, guaranty, or right of setoff at any time held by Administrative Agent
or any Lender for the payment of the Guarantor Obligations may be sold,
exchanged, waived, surrendered, or released. Neither Administrative Agent nor
any Lender shall have any obligation to protect, secure, perfect, or insure any
Lien at any time held by it as security for the Guarantor Obligations or for
this guaranty or any property subject thereto.

         2.5 GUARANTY ABSOLUTE AND UNCONDITIONAL. Each Guarantor waives any and
all notice of the creation, renewal, extension, or accrual of any of the
Guarantor Obligations and notice of or proof of reliance by Administrative Agent
or any Lender upon this guaranty or acceptance of this guaranty; the Guarantor
Obligations, and any of them, shall conclusively be deemed to have been created,
contracted or incurred, or renewed, extended, amended or waived, in reliance
upon this guaranty; and all dealings between Borrower and any of the Guarantors,
on the one hand, and Administrative Agent and Lenders, on the other hand,
likewise shall be conclusively presumed to have been had or 



                           GUARANTY AGREEMENT-Page 3
<PAGE>   76




consummated in reliance upon this guaranty. Each Guarantor waives diligence,
presentment, protest, demand for payment, and notice of default or nonpayment to
or upon Borrower or any Guarantors with respect to the Guarantor Obligations.
Each Guarantor understands and agrees that this guaranty shall be construed as a
continuing, absolute, and unconditional guaranty of payment without regard to
(a) the validity or enforceability of the Credit Agreement or any other Loan
Document, any of the Guarantor Obligations or any other collateral security
therefor or guaranty or right of setoff with respect thereto at any time or from
time to time held by Administrative Agent or any Lender, (b) any defense,
setoff, or counterclaim (other than a defense of payment or performance) which
may at any time be available to or be asserted by Borrower against
Administrative Agent or any Lender, or (c) any other circumstance whatsoever
(with or without notice to or knowledge of Borrower or the Guarantor) which
constitutes, or might be construed to constitute, an equitable or legal
discharge of Borrower for the Borrower Obligations, or of the Guarantor under
this guaranty, in bankruptcy, or in any other instance. When making any demand
hereunder or otherwise pursuing its rights and remedies hereunder against any
Guarantor, Administrative Agent or any Lender may, but shall be under no
obligation to, make a similar demand on or otherwise pursue such rights and
remedies as it may have against Borrower, any Guarantor, or any other Person or
against any collateral security or guaranty for the Guarantor Obligations or any
right of setoff with respect thereto, and any failure by Administrative Agent or
any Lender to make any such demand, to pursue their other rights or remedies, or
to collect any payments from Borrower, any Guarantor, or any other Person or to
realize upon any collateral security or guaranty or to exercise any right of
setoff, or any release of Borrower, any Guarantor, or any other Person or any
collateral security, guaranty, or right of setoff, shall not relieve any
Guarantor of any obligation or liability hereunder, and shall not impair or
affect the rights and remedies, whether express, implied, or available as a
matter of law, of Administrative Agent or any Lender against any Guarantor. For
the purposes hereof "demand" shall include the commencement and continuance of
any legal proceedings.

         2.6 REINSTATEMENT. This guaranty shall continue to be effective, or be
reinstated, as the case may be, if at any time payment, or any part thereof, of
any of the Guarantor Obligations is rescinded or must otherwise be restored or
returned by Administrative Agent or any Lender upon the insolvency, bankruptcy,
dissolution, liquidation, or reorganization of Borrower or any Guarantor, or
upon or as a result of the appointment of a receiver, intervenor, or conservator
of, or trustee or similar officer for, Borrower or any Guarantor or any
substantial part of its property, or otherwise, all as though such payments had
not been made.

         2.7 PAYMENTS. Each Guarantor hereby guarantees that payments hereunder
will be paid to Administrative Agent without setoff or counterclaim in lawful
money of the United States of America in immediately available funds at the
office of Administrative Agent located at 500 Throckmorton Street, Fort Worth,
Texas 76102, or at such other place as may be designated in writing by
Administrative Agent.

ARTICLE 3 - COVENANTS
- ---------------------

         Each Guarantor covenants and agrees with Administrative Agent and
Lenders that, from and after the date of this Agreement until the Guarantor
Obligations shall have been paid in full, no Letter of Credit is outstanding,
and the Total Commitment is terminated:

         3.1 COVENANTS IN CREDIT AGREEMENT. In the case of each Guarantor which
is not a party to the Credit Agreement, such Guarantor shall take, or shall
refrain from taking as the case may be, each action that is necessary to be
taken or not taken, as the case may be so that no Default or Event of Default is
caused by the failure to take such action or to refrain from taking such action
by such Guarantor.

         3.2 FURTHER DOCUMENTATION. At any time and from time to time, upon the
written request of Administrative Agent, and at the sole expense of the
Guarantors, each Guarantor will promptly and duly execute and deliver such
further instruments and documents and take such further actions as
Administrative Agent may reasonably request for the purpose of obtaining or
preserving the full benefits of this Agreement and of the rights and powers
herein granted.

ARTICLE 4 - MISCELLANEOUS
- -------------------------



                           GUARANTY AGREEMENT-Page 4
<PAGE>   77



         4.1 AMENDMENTS. Subject to the terms of the Credit Agreement, none of
the terms or provisions of this Agreement may be waived, amended, supplemented
or otherwise modified except by a written instrument executed by Borrower, each
affected Guarantor, and Administrative Agent, provided that any provision of
this Agreement imposing obligations on Borrower or any Guarantor may be waived
by Administrative Agent in a written instrument executed by Administrative
Agent.

         4.2 NOTICES. All notices, requests, and demands to or upon
Administrative Agent, Borrower, or any Guarantor hereunder shall be effected in
the manner provided for in Section 12.10 of the Credit Agreement; provided that
any such notice, request, or demand to or upon any Guarantor shall be addressed
to such Guarantor at its notice address set forth on SCHEDULE 1.

         4.3 NO WAIVER, COURSE OF CONDUCT; CUMULATIVE REMEDIES. Neither
Administrative Agent nor any Lender shall by any act (except by a written
instrument pursuant to Section 4.1), delay, indulgence, omission, or otherwise
be deemed to have waived any right or remedy hereunder or to have acquiesced in
any Event of Default. No failure to exercise, nor any delay in exercising, on
the part of Administrative Agent or any Lender, any right, power, or privilege
hereunder shall operate as a waiver thereof. No single or partial exercise of
any right, power, or privilege hereunder shall preclude any other or further
exercise thereof or the exercise of any other right, power, or privilege. A
waiver by Administrative Agent or any Lender of any right or remedy hereunder on
any one occasion shall not be construed as a bar to any right or remedy which
Administrative Agent or such Lender would otherwise have on any future occasion.
The rights and remedies herein provided are cumulative, may be exercised singly
or concurrently, and are not exclusive of any other rights or remedies provided
by law.

         4.4 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
successors and assigns of Borrower and each Guarantor and shall inure to the
benefit of Administrative Agent and Lenders and their successors and assigns;
provided that no Borrower or Guarantor may assign, transfer, or delegate any of
its rights or obligations under this Agreement without the prior written consent
of Administrative Agent.

         4.5 SETOFF. In addition to any rights and remedies of Lenders provided
by law, each Lender shall have the right, without prior notice to Borrower or
any Guarantor, any such notice being expressly waived by each to the extent
permitted by applicable law, upon any amount becoming due and payable by
Borrower or any Guarantor hereunder or under any other Loan Document (whether at
the stated maturity, by acceleration, or otherwise) to setoff and appropriate
and apply against such amount any and all deposits (general or special, time or
demand, provisional or final), in any currency, and any other credits,
indebtedness, or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Lender or any branch or agency thereof to or for the credit or the
account of Borrower or any Guarantor. Each Lender agrees promptly to notify
Borrower or the relevant Guarantor and Administrative Agent after any such
setoff and application made by such Lender, provided that, to the extent
permitted by applicable law, the failure to give such notice shall not affect
the validity of such setoff and application.

         4.6 COUNTERPARTS. This Agreement may be executed by one or more of the
parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument.

         4.7 SEVERABILITY. Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         4.8 SECTION HEADINGS. The section headings used in this Agreement are
for convenience of reference only and are not to affect the construction hereof
or be taken into consideration in the interpretation hereof.

         4.9 INTERPRETATION. This Agreement and the other Loan Documents
represent the agreement of Borrower, the Guarantors, Administrative Agent, and
Lenders with respect to the subject matter hereof, and there are no promises,
undertakings, representations, or warranties by Administrative Agent or any
Lender relative to the subject matter hereof not expressly set forth or referred
to herein or in the other Loan Documents.

or Guarantor at its address referred to in Section 4.2 or at such other address
of which Administrative Agent shall have been notified pursuant thereto;

                  (d) agree that nothing herein shall affect the right to effect
service of process in any other manner permitted by law or shall limit the right
to sue in any other jurisdiction; and

                  (e) waive, to the maximum extent not prohibited by law, any
right it may have to claim or recover in any legal action or proceeding referred
to in this Section any special, exemplary, punitive, or consequential damages.

         4.12 ACKNOWLEDGMENTS. Guarantors hereby acknowledge (a) each has been
advised by counsel in the negotiation, execution, and delivery of this Agreement
and the other Loan Documents to which each is a party; (b) neither
Administrative Agent nor any Lender has any fiduciary relationship with or duty
to Borrower or any Guarantor arising out of or in connection with this Agreement
or any of the other Loan Documents, and the relationship between Borrower and
the Guarantors, on the one hand, and Administrative Agent and Lenders, on the
other hand, is solely that of debtor and creditor; and (c) no joint venture is
created hereby or by the other Loan Documents or otherwise exists by virtue of
the transactions contemplated hereby among Lenders or among Borrower, the
Guarantors, and Lenders.

         4.13 WAIVER OF JURY TRIAL. GUARANTORS HEREBY KNOWINGLY AND
INTENTIONALLY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL
ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND

required to become a party to this Agreement shall become a Guarantor for all
purposes of this Agreement upon execution and delivery by such Subsidiary of an
assumption agreement in form and substance acceptable to Administrative Agent,

made and existing by or among them and Lenders with respect to the Obligations
is contained within the Written Loan Agreement and that no agreements or
promises exist among them and Lenders that are not reflected in the Written Loan
Agreement.

                  (b) THE WRITTEN LOAN AGREEMENT REPRESENTS THE FINAL AGREEMENT

ARTICLE 4 - COVENANTS
- ---------------------

         Borrower and Guarantors covenant and agree with Administrative Agent

Obligations and Guarantor Obligations are paid in full, no Letter of Credit is
outstanding, and the Total Commitment is terminated:

         4.1 COVENANTS IN CREDIT AGREEMENT. Borrower shall take, or shall
refrain from taking as the case may be, and shall cause each Subsidiary to take,
or refrain from taking, each action that is necessary to be taken or not taken,
as the case may be, so that no Default or Event of Default is caused by the
failure to take such action or to refrain from taking such action. In the case
of each Guarantor which is not a party to the Credit Agreement, such Guarantor
shall take, or shall refrain from taking as the case may be, each action that is
necessary to be taken or not taken, as the case may be so that no Default or
Event of Default is caused by the failure to take such action or to refrain from
taking such action by such Guarantor.

         4.2 DELIVERY OF PROMISSORY NOTES AND CHATTEL PAPER. If any amount

Paper, or similar instrument shall be immediately delivered to Administrative
Agent, duly indorsed in a manner satisfactory to Administrative Agent, to be
held as collateral pursuant to this Agreement.

         4.3 MAINTENANCE OF PERFECTED SECURITY INTEREST; FURTHER DOCUMENTATION.
Borrower and Guarantors shall maintain the security interest created by this
Agreement on the Pledged Securities as a perfected security interest having at
least the priority described in Sections 3.2 and shall defend such security
interest against the claims and demands of all Persons.

                  (b) Borrower will furnish to Administrative Agent from time to
time statements and schedules further identifying and describing the Pledged
Securities and such other reports in connection with the Pledged Securities as
Administrative Agent may reasonably request, all in reasonable detail.

                  (c) At any time and from time to time, upon the written
request of Administrative Agent, and at the sole expense of Borrower and
Guarantors, Borrower and Guarantors will promptly and duly execute and deliver
such further instruments and documents and take such further actions as
Administrative Agent may reasonably request for the purpose of obtaining or
preserving the full benefits of this Agreement and of the rights and powers
herein granted, including, without limitation, the filing of any financing or
continuation statements under the Code (or other similar laws) in effect in any
jurisdiction with respect to the security interests created hereby.

         4.4 CHANGES IN LOCATIONS, NAME, ETC. Borrower and Guarantors will not,
except upon not less than 10 days prior written notice to Administrative Agent
and delivery to the Administrative Agent of all additional executed financing
statements and other documents reasonably requested by Administrative Agent to
maintain the validity, perfection, and priority of the security interests
provided for herein:

                  (a) change the location of its chief executive office or sole
place of business from that referred to in SCHEDULE 1; or

                  (b) change its name, identity, or corporate structure to such
an extent that any financing statement filed by Administrative Agent in
connection with this Agreement would become misleading.

         4.5 PLEDGED SECURITIES. (a) If Borrower or any Guarantors shall become
entitled to receive or shall receive (i) any stock certificate (including,
without limitation, any certificate representing a stock dividend or a
distribution in connection with any reclassification increase or reduction of
capital or any certificate issued in connection with any reorganization), option
or rights in respect of the capital stock, partnership interests, or units of
any Issuer, whether in addition to, in substitution of, as a conversion of, or
in exchange for, any shares of the Pledged Stock, or otherwise in respect
thereof, or (ii) any promissory note, security, or rights in exchange for all or
any portion of any Pledged Note, or otherwise in respect thereof, Borrower and
Guarantors shall accept the same as the agent of Administrative Agent and
Lenders, hold the same in trust for Administrative Agent and deliver the same
forthwith to Administrative Agent in the exact form received, duly indorsed by
Borrower and Guarantors to Administrative Agent, if required, together with an

case of Pledged Notes) covering such certificate, security, or note, duly
executed in blank by Borrower and Guarantors and with, if Administrative Agent
so requests, signature guaranteed, to be held by Administrative Agent, subject
to the terms hereof, as additional collateral security for the Borrower
Obligations and Guarantor Obligations. Any sums paid upon or in respect of the

capital shall be made on or in respect of the Pledged Securities or any property
shall be distributed upon or with respect to the Pledged Securities pursuant to
the recapitalization or reclassification of the capital of any Issuer or
pursuant to the reorganization thereof, the property so distributed shall, to
the extent required by the Credit Agreement or during the continuation of an
Event of Default, be delivered to Administrative Agent to be held by it
hereunder as additional collateral security for the Borrower Obligations and
Guarantor Obligations. If any sums of money or property so paid or distributed
in respect of the Pledged Securities shall be received by Borrower or any
Guarantor, Borrower and Guarantors shall, until such money or property is paid
or delivered to Administrative Agent, hold such money or property in trust for
Lenders, segregated from other funds of Borrower and Guarantors, as additional
collateral security for the Borrower Obligations and Guarantor Obligations.

                  (b) Without the prior written consent of Administrative Agent,
Borrower and Guarantors will not (i) vote to enable, or take any other action to
permit, any Issuer to issue any stock or other equity securities of any nature
or to issue any other securities convertible into or granting the right to
purchase or exchange for any stock or other equity securities of any nature of
any Issuer, (ii) sell, assign, transfer, exchange, or otherwise dispose of, or
grant any option with respect to, the Pledged Securities or Proceeds thereof
(except pursuant to a transaction expressly permitted by the Credit Agreement),

claim of any Person with respect to, any of the Pledged Securities or Proceeds
thereof, or any interest therein, except for the security interests created by
this Agreement and Liens permitted by the Credit Agreement or (iv) enter into
any agreement or undertaking restricting the right or ability of Borrower,
Guarantors, or Administrative Agent to sell, assign, or transfer any of the
Pledged Securities or Proceeds thereof.

                  (c) In the case of each Subsidiary of Borrower or Guarantors

to Borrower and Guarantors of Administrative Agent's intent to exercise its
corresponding rights pursuant to Subsection 5.1(b), Borrower shall be permitted
to exercise all voting and corporate rights with respect to the Pledged
Securities; provided, however, that no vote shall be cast or corporate right
exercised or other action taken which, in Administrative Agent's reasonable
judgment, would result in any violation of any provision of the Credit
Agreement, this Agreement, or any other Loan Document.

                  (b) If an Event of Default shall occur and be continuing and
Administrative Agent shall deliver written notice (which notice need not be
given during the continuation of any Event of Default described in Subsections
8.01 (g) or (h) of the Credit Agreement) of its intent to exercise such rights
to Borrower and Guarantors, Administrative Agent shall have the right to receive

                            PLEDGE AGREEMENT-Page 15
<PAGE>   88



Event of Default described in Subsections 8.01 (g) or (h) of the Credit
Agreement) of its intent to exercise such rights to Borrower and Guarantors, any
or all of the Pledged Securities shall be registered in the name of
Administrative Agent or its nominee, and Administrative Agent or its nominee may
thereafter exercise (i) all voting, corporate, and other rights pertaining to
such Pledged Securities at any meeting of shareholders of the relevant Issuer or
Issuers or otherwise and (ii) any and all rights of conversion, exchange,

exercise by Borrower, Guarantors, or Administrative Agent of any right,
privilege, or option pertaining to such Pledged Securities, and in connection
therewith, the right to deposit and deliver any and all of the Pledged

Guarantors to exercise any such right, privilege, or option and shall not be
responsible for any failure to do so or delay in so doing.

                  (c) Borrower and Guarantors hereby authorize and instruct each
Issuer of any Pledged Securities pledged hereunder to (i) comply with any
instruction received by it from Administrative Agent in writing that (x) states
that an Event of Default has occurred and (y) is otherwise in accordance with
the terms of this Agreement, without any other or further instructions from
Borrower or Guarantors, and Borrower and Guarantors agree that each Issuer shall
be fully protected in so complying, and (ii) unless otherwise expressly
permitted hereby, pay any dividends or other payments with respect to the
Pledged Securities directly to Administrative Agent.

         5.2 PROCEEDS TO BE TURNED OVER. If an Event of Default shall occur and
be continuing, all Proceeds received by Borrower and Guarantors consisting of
cash, checks, and other near-cash items shall be held by such entity in trust
for Administrative Agent and Lenders, segregated from other funds of Borrower
and Guarantors, and shall, forthwith upon receipt by Borrower or any Guarantor,
be turned over to Administrative Agent in the exact form received (duly indorsed
by Borrower and Guarantors to Administrative Agent, if required). All Proceeds
received by Administrative Agent hereunder shall be held by Administrative Agent
in a Collateral Account maintained under its sole dominion and control. All
Proceeds while held by Administrative Agent in a Collateral Account (or by
Borrower in trust for Administrative Agent and Lenders) shall continue to be
held as collateral security for all the Borrower Obligations and Guarantor
Obligations and shall not constitute payment thereof until applied as provided
in Section 5.3.

         5.3 APPLICATION OF PROCEEDS. If an Event of Default has occurred and is
continuing, at any time at Administrative Agent's election, Administrative Agent
may apply all or any part of Proceeds held in any Collateral Account in payment
of the Borrower Obligations and Guarantor Obligations in such order as
Administrative Agent may elect, and any part of such funds which Administrative
Agent elects not so to apply and deems not required as collateral security for
the Borrower Obligations or Guarantor Obligations shall be paid over from time
to time by Administrative Agent to Borrower, Guarantors, or to whomsoever may be
lawfully entitled to receive the same. Any balance of such Proceeds remaining
after the Borrower Obligations and Guarantor Obligations shall have been paid in
full, no Letters of Credit shall be outstanding, and the Total Commitment is
terminated shall be paid over to the grantor of such collateral or to whomsoever
may be lawfully entitled to receive the same.

         5.4 CODE AND OTHER REMEDIES. If an Event of Default shall occur and be
continuing, Administrative Agent, on behalf of Lenders, may exercise, in
addition to all other rights and remedies granted to them in this Agreement and
in any other instrument or agreement securing, evidencing, or relating to the
Borrower Obligations or Guarantor Obligations, all rights and remedies of a
secured party under the Code or any other applicable law. Without limiting the
generality of the foregoing, Administrative Agent, without demand of performance
or other demand, presentment, protest, advertisement, or notice of any kind
(except any notice required by law referred to below) to or upon Borrower,
Guarantors, or any other Person (all and each of which demands, defenses,
advertisements, and notices are hereby waived), may in such circumstances
forthwith collect, receive, appropriate, and realize upon the Pledged
Securities, or any part thereof, and may forthwith sell, lease, assign, give
option or options to purchase, or otherwise dispose of and deliver the Pledged
Securities or any part thereof (or contract to do any of the foregoing), in one
or more parcels at public or private sale or sales, at any exchange, broker's
board or office of Administrative Agent or any Lender or elsewhere upon such
terms and conditions as it may deem advisable and at such prices as it may deem
best, for cash or on credit or for future delivery without assumption of any
credit risk. Administrative Agent


                            PLEDGE AGREEMENT-Page 16
<PAGE>   89



or any Lender shall have the right upon any such public sale or sales,
and, to the extent permitted by law, upon any such private sale or sales, to
purchase the whole or any part of the Pledged Securities so sold, free of any
right or equity of redemption in Borrower or Guarantors, which right or equity
is hereby waived and released. Administrative Agent shall apply the proceeds of
any action taken by it pursuant to this Section 5.4, after deducting all
reasonable costs and expenses of every kind incurred in connection therewith or
incidental to the care or safekeeping of any of the Pledged Securities or in
any way relating to the Pledged Securities or the rights of Administrative
Agent and Lenders hereunder, including, without limitation, reasonable
attorneys fees and disbursements, to the payment in whole or in part of the
Borrower Obligations or Guarantor Obligations, in such order as Administrative
Agent may elect, and only after such application and after the payment by
Administrative Agent of any other amount required by any provision of law,
including, without limitation, Section 9.504(a) of the Code, need
Administrative Agent account for the surplus, if any, to Borrower or
Guarantors. To the extent permitted by applicable law, Borrower and Guarantors
waive all claims, damages, and demands any may acquire against Administrative
Agent or any Lender arising out of the exercise by them of any rights
hereunder. If any notice of a proposed sale or other disposition of collateral
shall be required by law, such notice shall be deemed reasonable and proper if
given at least 10 days before such sale or other disposition.

         5.5 SALE OF PLEDGED STOCK. (a) Borrower and Guarantors recognize that
Administrative Agent may be unable to effect a public sale of any or all the
Pledged Stock, by reason of certain prohibitions contained in the Securities Act
of 1933, as amended, and applicable state securities laws or otherwise, and may
be compelled to resort to one or more private sales thereof to a restricted
group of purchasers which will be obliged to agree, among other things, to
acquire such securities for their own account for investment and not with a view
to the distribution or resale thereof. Borrower and Guarantors acknowledge and
agree that any such private sale may result in prices and other terms less
favorable than if such sale were a public sale and, notwithstanding such
circumstances, agree that any such private sale shall be deemed to have been
made in a commercially reasonable manner. Administrative Agent shall be under no
obligation to delay a sale of any of the Pledged Stock for the period of time
necessary to permit the Issuer thereof to register such securities for public
sale under the Securities Act of 1933, as amended, or under applicable state
securities laws, even if such Issuer would agree to do so.

                  (b) Borrower and Guarantors agree to use their best efforts to
do or cause to be done all such other acts as may be necessary to make such sale
or sales of all or any portion of the Pledged Stock pursuant to this Section 5.5
valid and binding and in compliance with any and all other applicable
requirements of law. Borrower and Guarantors further agree that a breach of any
of the covenants contained in this Section 5.5 will cause irreparable injury to
Administrative Agent and Lenders, that Administrative Agent and Lenders have no
adequate remedy at law in respect of such breach, and as a consequence that each
and every covenant contained in this Section 5.5 shall be specifically
enforceable against Borrower and Guarantors. Borrower and Guarantors hereby
waive and agree not to assert any defenses against an action for specific
performance of such covenants except for a defense that no Event of Default has
occurred under the Credit Agreement.

         5.6 WAIVER; DEFICIENCY. Borrower and Guarantors waive and agree not to
assert any rights or privileges which any may acquire under Section 9.112 of the
Code. Borrower and Guarantors shall remain liable for any deficiency if the
proceeds of any sale or other disposition of the Pledged Securities are
insufficient to pay the Borrower Obligations and Guarantor Obligations and the
reasonable fees and disbursements of any attorneys employed by Administrative
Agent or any Lender to collect such deficiency.

ARTICLE 6 - ADMINISTRATIVE AGENT
- --------------------------------

         6.1 ATTORNEY-IN-FACT. (a) Borrower and Guarantors hereby irrevocably
constitute and appoint Administrative Agent and any officer or agent thereof,
with full power of substitution, as its true and lawful attorney-in-fact with
full irrevocable power and authority in the place and stead of Borrower and
Guarantors and in their name or in its own name, for the purpose of carrying out
the terms of this Agreement, to take any and all appropriate action and to
execute any and all documents and instruments which may be necessary or
desirable to accomplish the purposes of this Agreement, and, without limiting
the generality of the foregoing, Borrower and Guarantors hereby give
Administrative Agent the power and right, on its behalf, without notice to or
assent by Borrower or Guarantors, to do any or all of the following:


                            PLEDGE AGREEMENT-Page 17
<PAGE>   90




                           (i) in the name of Borrower or Guarantors or its own
name, or otherwise, take possession of and indorse and collect any checks,
drafts, notes, acceptances, or other instruments for the payment of moneys due
with respect to any Pledged Securities and file any claim or take any other
action or proceeding in any court of law or equity or otherwise deemed
appropriate by Administrative Agent for the purpose of collecting any and all
such moneys due with respect to any Pledged Securities whenever payable;

                           (ii) pay or discharge taxes and Liens levied or
placed on or threatened against the Pledged Securities;

                           (iii) execute, in connection with any sale provided
for in Sections 5.2 or 5.3, any indorsements, assignments, or other instruments
of conveyance or transfer with respect to the Pledged Securities; and

                           (iv) (A) direct any party liable for any payment
under any of the Pledged Securities to make payment of any and all moneys due or
to become due thereunder directly to Administrative Agent or as Administrative
Agent shall direct; (B) ask or demand for, collect, receive payment of, and
receipt for, any and all moneys, claims, and other amounts due or to become due
at any time in respect of or arising out of any Pledged Securities; (C) sign and
indorse any invoices, freight or express bills, bills of lading, storage or
warehouse receipts, drafts against debtors, assignments, verifications, notices,
and other documents in connection with any of the Pledged Securities; (D)
commence and prosecute any suits, actions or proceedings at law or in equity in
any court of competent jurisdiction to collect the Pledged Securities or any
portion thereof and to enforce any other right in respect of any Pledged
Securities; (E) defend any suit, action, or proceeding brought against Borrower
with respect to any Pledged Securities; (F) settle, compromise, or adjust any
such suit, action, or proceeding and, in connection therewith, to give such
discharges or releases as Administrative Agent may deem appropriate; and (G)
generally sell, transfer, pledge, and make any agreement with respect to or
otherwise deal with any of the Pledged Securities as fully and completely as
though Administrative Agent were the absolute owner thereof for all purposes,
and do, at Administrative Agent's option and Borrower's and Guarantors' expense,
at any time, or from time to time, all acts and things which the Administrative
Agent deems necessary to protect, preserve, or realize upon the Pledged
Securities and Administrative Agent's and Lenders' security interests therein
and to effect the intent of this Agreement, all as fully and effectively as
Borrower might do.

Anything in this Subsection 6.1(a) to the contrary notwithstanding,
Administrative Agent agrees that it will not exercise any rights under the power
of attorney provided for in this Subsection 6.1(a) unless an Event of Default
shall have occurred and be continuing.

                  (b) If Borrower or Guarantors fail to perform or comply with
any of their agreements contained herein, Administrative Agent, at its option,
but without any obligation so to do, may perform or comply, or otherwise cause
performance or compliance, with such agreement.

                  (c) Borrower and Guarantors hereby ratify all that
Administrative Agent as their attorney-in-fact shall lawfully do or cause to be
done by virtue hereof. All powers, authorizations, and agencies contained in
this Agreement are coupled with an interest and are irrevocable until this
Agreement is terminated and the security interests created hereby are released.

         6.2 DUTY OF ADMINISTRATIVE AGENT. Administrative Agent's sole duty with
respect to the custody, safekeeping, and physical preservation of the Pledged
Securities in its possession, under Section 9.207 of the Code or otherwise,
shall be to deal with it in the same manner as Administrative Agent deals with
similar property for its own account. Neither Administrative Agent, any Lender
nor any of their respective officers, directors, employees, or agents shall be
liable for failure to demand, collect, or realize upon any of the Pledged
Securities or for any delay in doing so or shall be under any obligation to sell
or otherwise dispose of any Pledged Securities upon the request of Borrower,
Guarantors, or any other Person or to take any other action whatsoever with
regard to the Pledged Securities or any part thereof. The powers conferred on
Administrative Agent and Lenders hereunder are solely to protect Administrative
Agent's and Lenders' interests in the Pledged Securities and shall not impose
any duty upon Administrative Agent or any Lender to exercise any such powers.
Administrative Agent and Lenders shall be accountable only for amounts that they
actually receive as a result of the exercise of such powers, and neither they
nor any of their officers, directors, employees, or agents shall be responsible
to Borrower or Guarantors for any act or failure to act hereunder, except for
their own gross negligence or willful misconduct.


                            PLEDGE AGREEMENT-Page 18
<PAGE>   91



         6.3 FINANCING STATEMENTS. Pursuant to Section 9.402 of the Code and any
other applicable law, Borrower and Guarantors authorize Administrative Agent to
file or record financing statements and other filing or recording documents or
instruments with respect to the collateral without their signature in such form
and in such offices as Administrative Agent reasonably determines appropriate to
perfect the security interests of Administrative Agent under this Agreement. A
photographic or other reproduction of this Agreement shall be sufficient as a
financing statement or other filing or recording document or instrument for
filing or recording in any jurisdiction.

         6.4 AUTHORITY OF ADMINISTRATIVE AGENT. Borrower and Guarantors
acknowledge that the rights and responsibilities of Administrative Agent under
this Agreement with respect to any action taken by Administrative Agent or the
exercise or non-exercise by Administrative Agent of any option, voting right,
request, judgment or other right or remedy provided for herein or resulting or
arising out of this Agreement shall, as between Administrative Agent and
Lenders, be governed by the Credit Agreement and by such other agreements with
respect thereto as may exist from time to time among them, but, as between
Administrative Agent and Borrower and Guarantors, Administrative Agent shall be
conclusively presumed to be acting as agent for Lenders with full and valid
authority so to act or refrain from acting, and Borrower and Guarantors shall
not be under any obligation, or entitlement, or make any inquiry respecting such
authority.

ARTICLE 7 - MISCELLANEOUS
- -------------------------

         7.1 AMENDMENTS. Subject to the terms of the Credit Agreement, none of
the terms or provisions of this Agreement may be waived, amended, supplemented
or otherwise modified except by a written instrument executed by Borrower,
Guarantors, and Administrative Agent, provided that any provision of this
Agreement imposing obligations on Borrower or Guarantors may be waived by
Administrative Agent in a written instrument executed by Administrative Agent.

         7.2 NOTICES. All notices, requests, and demands to or upon
Administrative Agent or Borrower hereunder shall be effected in the manner
provided for in Section 12.10 of the Credit Agreement; provided that any such
notice, request, or demand to or upon any Guarantor shall be addressed to such
Guarantor at its notice address set forth on SCHEDULE 1.

         7.3 NO WAIVER, COURSE OF CONDUCT; CUMULATIVE REMEDIES. Neither
Administrative Agent nor any Lender shall by any act (except by a written
instrument pursuant to Section 7.1), delay, indulgence, omission, or otherwise
be deemed to have waived any right or remedy hereunder or to have acquiesced in
any Event of Default. No failure to exercise, nor any delay in exercising, on
the part of Administrative Agent or any Lender, any right, power, or privilege
hereunder shall operate as a waiver thereof. No single or partial exercise of
any right, power, or privilege hereunder shall preclude any other or further
exercise thereof or the exercise of any other right, power, or privilege. A
waiver by Administrative Agent or any Lender of any right or remedy hereunder on
any one occasion shall not be construed as a bar to any right or remedy which
Administrative Agent or such Lender would otherwise have on any future occasion.
The rights and remedies herein provided are cumulative, may be exercised singly
or concurrently, and are not exclusive of any other rights or remedies provided
by law.

         7.4 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
successors and assigns of Borrower and Guarantors and shall inure to the benefit
of Administrative Agent and Lenders and their successors and assigns; provided
that Borrower and Guarantors may not assign, transfer, or delegate any of their
rights or obligations under this Agreement without the prior written consent of
Administrative Agent.

         7.5 SETOFF. In addition to any rights and remedies of Lenders provided
by law, each Lender shall have the right, without prior notice to Borrower or
Guarantors, any such notice being expressly waived to the extent permitted by
applicable law, upon any amount becoming due and payable by Borrower or any
Guarantors hereunder or under any other Loan Document (whether at the stated
maturity, by acceleration, or otherwise) to setoff and appropriate and apply
against such amount any and all deposits (general or special, time or demand,
provisional or final), in any currency, and any other credits, indebtedness, or
claims, in any currency, in each case whether direct or indirect, absolute or
contingent, matured or unmatured, at any time held or owing by such Lender or
any branch or agency thereof to or for the credit or the account of Borrower.
Each Lender agrees promptly to notify Borrower, Guarantors, 


                            PLEDGE AGREEMENT-Page 19
<PAGE>   92



and Administrative Agent after any such setoff and application made by such
Lender, provided that, to the extent permitted by applicable law, the failure to
give such notice shall not affect the validity of such setoff and application.

         7.6 COUNTERPARTS. This Agreement may be executed by one or more of the
parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument.

         7.7 SEVERABILITY. Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         7.8 SECTION HEADINGS. The section headings used in this Agreement are
for convenience of reference only and are not to affect the construction hereof
or be taken into consideration in the interpretation hereof.

         7.9 INTERPRETATION. This Agreement and the other Loan Documents
represent the agreement of Borrower, Guarantors, Administrative Agent, and
Lenders with respect to the subject matter hereof, and there are no promises,
undertakings, representations, or warranties by Administrative Agent or any
Lender relative to the subject matter hereof not expressly set forth or referred
to herein or in the other Loan Documents.

         7.10 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED
AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS WITHOUT
REGARD TO ITS RULES GOVERNING CONFLICT OF LAWS. BORROWER AGREES THAT VENUE FOR
ANY ACTION OR CLAIM RELATED TO THIS AGREEMENT SHALL BE IN TARRANT COUNTY, TEXAS.

         7.11 SUBMISSION TO JURISDICTION; WAIVERS. Borrower and Guarantors
hereby irrevocably and unconditionally:

                  (a) submit for themselves and their property in any legal

proceeding may be effected by mailing a copy thereof by registered or certified

or Guarantors at their address referred to in Section 7.2 or at such other
address of which Administrative Agent shall have been notified pursuant thereto;

                  (d) agree that nothing herein shall affect the right to effect

                  (e) waive, to the maximum extent not prohibited by law, any
right any may have to claim or recover in any legal action or proceeding
referred to in this Section any special, exemplary, punitive, or consequential
damages.

(a) each has been advised by counsel in the negotiation, execution, and delivery
of this Agreement and the other Loan Documents to which each is a party; (b)
neither Administrative Agent nor any Lender has any fiduciary relationship with
or duty to Borrower or Guarantors arising out of or in connection with this
Agreement or any of the other Loan Documents, and the relationship between

on the other hand, is solely that of debtor and creditor; and (c) no joint

BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO

the Code (a) upon completion of the filings and other actions specified on
SCHEDULE 2 (which, in the case of all filings and other documents referred to on

executed form) will constitute valid perfected security interests in all
Collateral in favor of Administrative Agent, for the ratable benefit of Lenders,
as collateral security for the Borrower Obligations and the Guarantor
Obligations, enforceable in accordance with the terms hereof against all
creditors of Borrower or any Guarantor and any Persons purporting to purchase
any Collateral from Borrower or any Guarantor and (b) are prior to all other
Liens on the Collateral except for Permitted Encumbrances.

         3.3 CHIEF EXECUTIVE OFFICE. On the date hereof, each Guarantor's

                         COMPLIANCE CERTIFICATE-Page 28

<PAGE>   101



action that is necessary to be taken or not taken, as the case may be so that no
Default or Event of Default is caused by the failure to take such action or to
refrain from taking such action by such Guarantor.

         4.2 DELIVERY OF PROMISSORY NOTES AND CHATTEL PAPER. If any amount
payable under or in connection with any of the Collateral is or becomes

a value or a principal amount of $100,000 or more, the promissory note, Chattel
Paper, or similar instrument shall be immediately delivered to Administrative
Agent, duly indorsed in a manner satisfactory to Administrative Agent, to be
held as Collateral pursuant to this Agreement.

         4.3 MAINTENANCE OF PERFECTED SECURITY INTEREST; FURTHER DOCUMENTATION.

described in Section 3.2 and shall defend such security interest against the

Agent from time to time statements and schedules further identifying and
describing the Collateral and such other reports in connection with the

detail.

                  (c) At any time and from time to time, upon the written
request of Administrative Agent, and at the sole expense of Borrower and
Guarantors, Borrower and each Guarantor will promptly and duly execute and
deliver such further instruments and documents and take such further actions as
Administrative Agent may reasonably request for the purpose of obtaining or
preserving the full benefits of this Agreement and of the rights and powers
herein granted, including, without limitation, the filing of any financing or
continuation statements under the Code (or other similar laws) in effect in any
jurisdiction with respect to the security interests created hereby.

         4.4 CHANGES IN LOCATIONS, NAME, ETC. Borrower and each Guarantor will
not, except upon not less than 10 days prior written notice to Administrative
Agent and delivery to the Administrative Agent of all additional executed
financing statements and other documents reasonably requested by Administrative
Agent to maintain the validity, perfection, and priority of the security
interests provided for herein:

                  (a) change the location of its chief executive office or sole
place of business from that referred to in SCHEDULE 1; or

                  (b) change its name, identity, or corporate structure to such

ARTICLE 5 - REMEDIAL PROVISIONS
- -------------------------------

         5. l CERTAIN MATTERS RELATING TO RECEIVABLES. (a) Administrative Agent
shall have the right, upon the occurrence and during the continuance of an Event
of Default, to make test verifications of the Receivables in any manner and
through any medium that it reasonably considers advisable, and Borrower and each
Guarantor shall furnish all such assistance and information as Administrative
Agent may require in connection with such test verifications. At any time and
from time to time, upon the occurrence and during the continuance of an Event of
Default, upon Administrative Agent's reasonable request and at the expense of
Borrower or the relevant Guarantor, Borrower and each Guarantor shall cause
independent public accountants or others satisfactory to Administrative Agent to
furnish to Administrative Agent reports showing reconciliations, aging and test
verifications of, and trial balances for, the Receivables.

                  (b) Administrative Agent hereby authorizes Borrower and each
Guarantor to collect their respective Receivables, subject to Administrative
Agent's direction and control, and Administrative Agent may curtail or terminate
said authority at any time after the occurrence and during 



                         COMPLIANCE CERTIFICATE-Page 29
<PAGE>   102



the continuance of an Event of Default. If required by Administrative Agent at
any time after the occurrence and during the continuance of an Event of Default,
any payments of Receivables, when collected by Borrower or any Guarantor, (i)
shall be forthwith (and, in any event, within two Business Days) deposited in
the exact form received, duly indorsed by Borrower and each Guarantor to
Administrative Agent, if required, in a Collateral Account maintained under the
sole dominion and control of Administrative Agent, subject to withdrawal by
Administrative Agent for the account of Lenders only, as provided in Section
5.4, and (ii) until so turned over, shall be held by Borrower and each Guarantor
in trust for Administrative Agent and Lenders, segregated from other funds of
Borrower and Guarantors. Each such deposit of Proceeds of Receivables shall be
accompanied by a report identifying in reasonable detail the nature and source
of the payments included in the deposit.

                  (c) At Administrative Agent's request, upon the occurrence and
during the continuance of an Event of Default, Borrower and each Guarantor shall
deliver to Administrative Agent all original and other documents evidencing, and
relating to, the agreements and transactions which gave rise to the Receivables,
including, without limitation, all original orders, invoices and shipping
receipts.

         5.2 COMMUNICATIONS WITH OBLIGORS; GUARANTORS REMAIN LIABLE. (a)
Administrative Agent in its own name or in the name of others may at any time
after the occurrence and during the continuance of an Event of Default
communicate with obligors under the Receivables and parties to the Contracts to
verify with them to Administrative Agent's satisfaction the existence, amount,
and terms of any Receivables or contracts.

                  (b) Upon the request of Administrative Agent at any time after
the occurrence and during the continuance of an Event of Default, Borrower and
each Guarantor shall notify obligors on the Receivables and parties to the
Contracts that the Receivables and the contracts have been assigned to
Administrative Agent for the ratable benefit of Lenders and that payments in
respect thereof shall be made directly to Administrative Agent.

                  (c) Anything herein to the contrary notwithstanding, Borrower
and each Guarantor shall remain liable under each of the Receivables and
Contracts to observe and perform all the conditions and obligations to be
observed and performed by it thereunder, all in accordance with the terms of any
agreement giving rise thereto. Neither Administrative Agent nor any Lender shall
have any obligation or liability under any Receivable (or any agreement giving
rise thereto) or Contract, by reason of or arising out of this Agreement or the
receipt by Administrative Agent or any Lender of any payment relating thereto,
nor shall Administrative Agent or any Lender be obligated in any manner to
perform any of the obligations of Borrower or any Guarantor under or pursuant to
any Receivable (or any agreement giving rise thereto) or Contract, to make any
payment, to make any inquiry as to the nature or the sufficiency of any payment
received by it or as to the sufficiency of any performance by any party
thereunder, to present or file any claim, to take any action to enforce any
performance, or to collect the payment of any amounts which may have been
assigned to it or to which it may be entitled at any time or times.

         5.3 PROCEEDS TO BE TURNED OVER. In addition to the rights of
Administrative Agent and Lenders specified in Section 5.1 with respect to
payments of Receivables, if an Event of Default shall occur and be continuing,
all Proceeds received by Borrower or any Guarantor consisting of cash, checks,
and other near-cash items shall be held by such entity in trust for
Administrative Agent and Lenders, segregated from other funds of Borrower and
Guarantors, and shall, forthwith upon receipt by Borrower or Guarantors, be
turned over to Administrative Agent in the exact form received (duly indorsed by
Borrower or such Guarantor to Administrative Agent, if required). All Proceeds
received by Administrative Agent hereunder shall be held by Administrative Agent
in a Collateral Account maintained under its sole dominion and control. All
Proceeds while held by Administrative Agent in a Collateral Account (or by
Borrower or Guarantors in trust for Administrative Agent and Lenders) shall
continue to be held as collateral security for all Borrower Obligations and
Guarantor Obligations and shall not constitute payment thereof until applied as
provided in Section 5.4.

         5.4 APPLICATION OF PROCEEDS. If an Event of Default has occurred and is
continuing, at any time at Administrative Agent's election, Administrative Agent
may apply all or any part of Proceeds held 


                         COMPLIANCE CERTIFICATE-Page 30
<PAGE>   103



in any Collateral Account in payment of the Borrower Obligations or Guarantor
Obligations in such order as Administrative Agent may elect, and any part of
such funds which Administrative Agent elects not so to apply and deems not
required as collateral security for the Borrower Obligations or Guarantor
Obligations shall be paid over from time to time by Administrative Agent to
Borrower or Guarantors or to whomsoever may be lawfully entitled to receive the
same. Any balance of such Proceeds remaining after the Borrower Obligations and
Guarantor Obligations shall have been paid in full, no Letters of Credit shall
be outstanding, and the Total Commitment is terminated shall be paid over to the
grantor of such Collateral or to whomsoever may be lawfully entitled to receive
the same.

         5.5 CODE AND OTHER REMEDIES. If an Event of Default shall occur and be
continuing, Administrative Agent, on behalf of Lenders, may exercise, in
addition to all other rights and remedies granted to them in this Agreement and
in any other instrument or agreement securing, evidencing, or relating to the
Borrower Obligations or Guarantor Obligations, all rights and remedies of a
secured party under the Code or any other applicable law. Without limiting the
generality of the foregoing, Administrative Agent, without demand of performance
or other demand, presentment, protest, advertisement, or notice of any kind
(except any notice required by law referred to below) to or upon Borrower or any
Guarantor, or any other Person (all and each of which demands, defenses,
advertisements, and notices are hereby waived), may in such circumstances
forthwith collect, receive, appropriate, and realize upon the Collateral, or any
part thereof, and may forthwith sell, lease, assign, give option or options to
purchase, or otherwise dispose of and deliver the Collateral or any part thereof
(or contract to do any of the foregoing), in one or more parcels at public or
private sale or sales, at any exchange, broker's board or office of
Administrative Agent or any Lender or elsewhere upon such terms and conditions
as it may deem advisable and at such prices as it may deem best, for cash or on
credit or for future delivery without assumption of any credit risk.
Administrative Agent or any Lender shall have the right upon any such public
sale or sales, and, to the extent permitted by law, upon any such private sale
or sales, to purchase the whole or any part of the Collateral so sold, free of
any right or equity of redemption in Borrower or any Guarantor, which right or
equity is hereby waived and released. Borrower and each Guarantor further agree,
at Administrative Agent's request, to assemble the Collateral and make it
available to Administrative Agent at places which Administrative Agent shall
reasonably select, whether at Borrower's or such Guarantor's premises or
elsewhere. Administrative Agent shall apply the proceeds of any action taken by
it pursuant to this Section 5.5, after deducting all reasonable costs and
expenses of every kind incurred in connection therewith or incidental to the
care or safekeeping of any of the Collateral or in any way relating to the
Collateral or the rights of Administrative Agent and Lenders hereunder,
including, without limitation, reasonable attorneys fees and disbursements, to
the payment in whole or in part of the Borrower Obligations and Guarantor
Obligations, in such order as Administrative Agent may elect, and only after
such application and after the payment by Administrative Agent of any other
amount required by any provision of law, including, without limitation, Section
9.504(a) of the Code, need Administrative Agent account for the surplus, if any,
to Borrower and Guarantors. To the extent permitted by applicable law, Borrower
and each Guarantor waive all claims, damages, and demands it may acquire against
Administrative Agent or any Lender arising out of the exercise by them of any
rights hereunder. If any notice of a proposed sale or other disposition of

- --------------------------------

         6.1 ATTORNEY-IN-FACT. (a) Borrower and each Guarantor hereby
irrevocably constitute and appoint Administrative Agent and any officer or agent
thereof, with full power of substitution, as their true and lawful
attorney-in-fact with full irrevocable power and authority in the place and
stead of 


                         COMPLIANCE CERTIFICATE-Page 31
<PAGE>   104



Borrower and Guarantors and in their name or in its own name, for the
purpose of carrying out the terms of this Agreement, to take any and all
appropriate action and to execute any and all documents and instruments which
may be necessary or desirable to accomplish the purposes of this Agreement, and,
without limiting the generality of the foregoing, Borrower and each Guarantor
hereby give Administrative Agent the power and right, on their behalf, without
notice to or assent by Borrower or any Guarantor, to do any or all of the
following:

                           (i) in the name of Borrower or any Guarantor or its
own name, or otherwise, take possession of and indorse and collect any checks,
drafts, notes, acceptances, or other instruments for the payment of moneys due
under any Receivable or Contract or with respect to any other Collateral and
file any claim or take any other action or proceeding in any court of law or
equity or otherwise deemed appropriate by Administrative Agent for the purpose
of collecting any and all such moneys due under any Receivable or Contract or
with respect to any other Collateral whenever payable;

                           (ii) pay or discharge taxes and Liens levied or
placed on or threatened against the Collateral, effect any repairs or any
insurance called for by the terms of this Agreement, and pay all or any part of
the premiums therefor and the costs thereof;

                           (iii) execute, in connection with any sale provided
for in Sections 5.5 any indorsements, assignments, or other instruments of
conveyance or transfer with respect to the Collateral; and

                           (iv) (A) direct any party liable for any payment
under any of the Collateral to make payment of any and all moneys due or to
become due thereunder directly to Administrative Agent or as Administrative
Agent shall direct; (B) ask or demand for, collect, receive payment of, and
receipt for, any and all moneys, claims, and other amounts due or to become due
at any time in respect of or arising out of any Collateral; (C) sign and indorse
any invoices, freight or express bills, bills of lading, storage or warehouse
receipts, drafts against debtors, assignments, verifications, notices, and other
documents in connection with any of the Collateral; (D) commence and prosecute
any suits, actions or proceedings at law or in equity in any court of competent
jurisdiction to collect the Collateral or any portion thereof and to enforce any
other right in respect of any Collateral; (E) defend any suit, action, or
proceeding brought against Borrower or a Guarantor with respect to any
Collateral; (F) settle, compromise, or adjust any such suit, action, or
proceeding and, in connection therewith, to give such discharges or releases as
Administrative Agent may deem appropriate; and (G) generally sell, transfer,
pledge, and make any agreement with respect to or otherwise deal with any of the
Collateral as fully and completely as though Administrative Agent were the
absolute owner thereof for all purposes, and do, at Administrative Agent's
option and Borrower and Guarantors' expense, at any time, or from time to time,
all acts and things which the Administrative Agent deems necessary to protect,
preserve, or realize upon the Collateral and Administrative Agent's and Lenders'
security interests therein and to effect the intent of this Agreement, all as
fully and effectively as Borrower and Guarantors might do.

Anything in this Subsection 6.1(a) to the contrary notwithstanding,
Administrative Agent agrees that it will not exercise any rights under the power
of attorney provided for in this Subsection 6.1(a) unless an Event of Default
shall have occurred and be continuing.

                  (b) If Borrower or any Guarantor fails to perform or comply
with any of its agreements contained herein, Administrative Agent, at its
option, but without any obligation so to do, may perform or comply, or otherwise
cause performance or compliance, with such agreement.

                  (c) Borrower and each Guarantor hereby ratify all that
Administrative Agent as its attorney-in-fact shall lawfully do or cause to be
done by virtue hereof. All powers, authorizations, and agencies contained in
this Agreement are coupled with an interest and are irrevocable until this
Agreement is terminated and the security interests created hereby are released.

         6.2 DUTY OF ADMINISTRATIVE AGENT. Administrative Agent's sole duty with
respect to the custody, safekeeping, and physical preservation of the Collateral
in its possession, under Section 9.207 of the Code or otherwise, shall be to
deal with it in the same manner as Administrative Agent deals with 


                         COMPLIANCE CERTIFICATE-Page 32
<PAGE>   105



similar property for its own account. Neither Administrative Agent, any Lender
nor any of their respective officers, directors, employees, or agents shall be
liable for failure to demand, collect, or realize upon any of the Collateral or
for any delay in doing so or shall be under any obligation to sell or otherwise
dispose of any Collateral upon the request of Borrower or any Guarantor or any
other Person or to take any other action whatsoever with regard to the
Collateral or any part thereof. The powers conferred on Administrative Agent and
Lenders hereunder are solely to protect Administrative Agent's and Lenders'
interests in the Collateral and shall not impose any duty upon Administrative
Agent or any Lender to exercise any such powers. Administrative Agent and
Lenders shall be accountable only for amounts that they actually receive as a
result of the exercise of such powers, and neither they nor any of their
officers, directors, employees, or agents shall be responsible to Borrower or
any Guarantor for any act or failure to act hereunder, except for their own
gross negligence or willful misconduct.

         6.3 FINANCING STATEMENTS. Pursuant to Section 9.402 of the Code and any
other applicable law,Borrower and each Guarantor authorize Administrative Agent
to file or record financing statements and other filing or recording documents
or instruments with respect to the Collateral without their signature in such
form and in such offices as Administrative Agent reasonably determines
appropriate to perfect the security interests of Administrative Agent under this
Agreement. A photographic or other reproduction of this Agreement shall be
sufficient as a financing statement or other filing or recording document or
instrument for filing or recording in any jurisdiction.

         6.4 AUTHORITY OF ADMINISTRATIVE AGENT. Borrower and each Guarantor
acknowledge that the rights and responsibilities of Administrative Agent under
this Agreement with respect to any action taken by Administrative Agent or the
exercise or non-exercise by Administrative Agent of any option, voting right,
request, judgment or other right or remedy provided for herein or resulting or
arising out of this Agreement shall, as between Administrative Agent and
Lenders, be governed by the Credit Agreement and by such other agreements with
respect thereto as may exist from time to time among them, but, as between
Administrative Agent and Borrower and the Guarantors, Administrative Agent shall
be conclusively presumed to be acting as agent for Lenders with full and valid
authority so to act or refrain from acting, and no Borrower or Guarantor shall
be under any obligation, or entitlement, or make any inquiry respecting such
authority.

ARTICLE 7 - MISCELLANEOUS
- -------------------------

         7.1 AMENDMENTS. Subject to the terms of the Credit Agreement, none of
the terms or provisions of this Agreement may be waived, amended, supplemented
or otherwise modified except by a written instrument executed by Borrower, each
affected Guarantor, and Administrative Agent, provided that any provision of
this Agreement imposing obligations on Borrower or any Guarantor may be waived
by Administrative Agent in a written instrument executed by Administrative
Agent.

         7.2 NOTICES. All notices, requests, and demands to or upon
Administrative Agent, Borrower, or any Guarantor hereunder shall be effected in
the manner provided for in Section 12.10 of the Credit Agreement; provided that
any such notice, request, or demand to or upon any Guarantor shall be addressed
to such Guarantor at its notice address set forth on SCHEDULE 1.

         7.3 NO WAIVER, COURSE OF CONDUCT; CUMULATIVE REMEDIES. Neither
Administrative Agent nor any Lender shall by any act (except by a written
instrument pursuant to Section 7.1), delay, indulgence, omission, or otherwise
be deemed to have waived any right or remedy hereunder or to have acquiesced in
any Event of Default. No failure to exercise, nor any delay in exercising, on
the part of Administrative Agent or any Lender, any right, power, or privilege
hereunder shall operate as a waiver thereof. No single or partial exercise of
any right, power, or privilege hereunder shall preclude any other or further
exercise thereof or the exercise of any other right, power, or privilege. A
waiver by Administrative Agent or any Lender of any right or remedy hereunder on
any one occasion shall not be construed as a bar to any right or remedy which
Administrative Agent or such Lender would otherwise have on any future occasion.
The rights and remedies herein provided are cumulative, may be exercised singly
or concurrently, and are not exclusive of any other rights or remedies provided
by law.


                         COMPLIANCE CERTIFICATE-Page 33

of Administrative Agent.

by law, each Lender shall have the right, without prior notice to Borrower or
any Guarantor, any such notice being expressly waived by each to the extent
permitted by applicable law, upon any amount becoming due and payable by
Borrower or any Guarantor hereunder or under any other Loan Document (whether at
the stated maturity, by acceleration, or otherwise) to setoff and appropriate
and apply against such amount any and all deposits (general or special, time or
demand, provisional or final), in any currency, and any other credits,
indebtedness, or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Lender or any branch or agency thereof to or for the credit or the
account of Borrower or any Guarantor. Each Lender agrees promptly to notify
Borrower or the relevant Guarantor and Administrative Agent after any such
setoff and application made by such Lender, provided that, to the extent
permitted by applicable law, the failure to give such notice shall not affect
the validity of such setoff and application.

         7.6 COUNTERPARTS. This Agreement may be executed by one or more of the
parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument.

         7.7 SEVERABILITY. Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         7.8 SECTION HEADINGS. The section headings used in this Agreement are
for convenience of reference only and are not to affect the construction hereof
or be taken into consideration in the interpretation hereof.

         Borrower previously delivered to Lenders, and fairly present the
         consolidated business and financial condition of Borrower as of the

         there does not exist on the date hereof, and there did not exist on the
         date of such financial statements, any condition or event which
         constitutes a Default or Event of Default; provided, that for any

         financial statements.

                  (iv) A review of the activities of Borrower during the Subject
         Period has been made under my supervision with a view to determining
         whether, during the Subject Period, Borrower has kept, observed,
         performed, and fulfilled all of its obligations under the Loan
         Documents, and during the Subject Period, Borrower kept, observed,
         performed, and fulfilled each and every covenant and condition to the
         Loan Documents (except for the deviations, if any, set forth on the
         exhibits annexed hereto).

                  (v) Attached hereto as EXHIBIT D are detailed calculations
