Item 1. Business.

General development of business

      KCS Energy, Inc. "KCS" or the "Company" is an independent oil and gas
company engaged in the acquisition, exploration, exploitation and production of
domestic oil and natural gas properties. The Company was formed in 1988 in
connection with the spin-off of the non-utility operations of NUI Corporation, a
New Jersey-based natural gas distribution company that had been engaged in the
oil and gas exploration and production business since the late 1960s. The
Company's properties are located in four distinct areas: the Mid-Continent,
onshore Gulf Coast and Rocky Mountain regions and, primarily through its
Volumetric Production Payment Program ("VPP Program"), the Gulf of Mexico.

      Several important developments have had and will continue to have a
significant impact on the Company's financial condition and results of
operations. On December 23, 1996, the Company and Tennessee Gas Pipeline Company
("Tennessee Gas") entered into a settlement covering all claims and litigation
between them related to an above-market, take-or-pay contract (the "Tennessee
Gas Contract"). As part of the settlement, the Tennessee Gas Contract was
terminated effective January 1, 1997, approximately two years prior to its
expiration date. See Note 11 to Consolidated Financial Statements. Prior to its
termination, the Tennessee Gas Contract had a material and positive effect on
the Company's gas revenue, income and cash flow.

      As of December 31, 1996, the Company completed the arrangements for the
Medallion Acquisition (see Note 4 to Consolidated Financial Statements),
effectively doubling its oil and gas reserves and giving it a substantial
presence in the Mid-Continent region.

      During 1997, the Company sold its principal natural gas transportation
asset, the Texas intrastate pipeline, and its third-party gas marketing
operations realizing proceeds of $28.5 million and an after-tax gain of $5.4
million. Accordingly, the financial statements included in this report reflect
the natural gas transportation and marketing operations as discontinued
operations.

      These developments transformed the Company from an enterprise heavily
dependent on the Bob West Field and the Tennessee Gas Contract, with marketing
and transportation operations, to a Company focused on exploration and
production, with a portfolio of properties in four distinct areas: the
Mid-Continent, Onshore Gulf Coast and Rocky Mountain regions and, primarily
through the VPP Program, the Gulf of Mexico. Production from the Bob West Field,
which in 1995 accounted for 36% of total production and 72% of the Company's oil
and gas revenues, accounted for less than 3%, 5% and 40% of total oil and gas
revenue in 1998, 1997 and 1996, respectively.

      During 1997 and 1998, as the result of very low prices for natural gas and
crude oil and, in 1998, disappointing performance of certain prospects in the
Rocky Mountains, the Company has incurred significant losses due to non-cash
ceiling writedowns of its oil and gas assets. Additionally, in 1998 the Company
was required under applicable accounting principles to reduce to zero the book
value of net deferred tax assets. As a result of these adjustments, the Company
had negative stockholders' equity as of December 31, 1998 and has violated
certain covenants in its revolving bank credit agreements. See Management's
Discussion and Analysis of Financial Condition and Results of Operations
Liquidity and Capital Resources and Notes 2 and 7 to Consolidated Financial
Statements.

Forward-looking Statements

      The information discussed in this Form 10-K includes "forward-looking
statements" within the meaning of Section 27A of the Securities Act of 1933, as
amended (the "Securities Act"), and Section 21E of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"). All statements other than statements
of historical facts included herein regarding planned capital expenditures,
increases in oil and gas production, the number of anticipated wells to be
drilled after the date hereof, the Company's financial position, business
strategy and other plans and objectives for future operations, are
forward-looking statements. Although the Company believes that the expectations
reflected in such forward-looking statements are reasonable, they do involve
certain assumptions, risks and uncertainties, and the Company can give no
assurance that such expectations will prove to be correct. The Company's actual
results could differ materially from those anticipated in these forward-looking
statements as a result of certain factors, including the timing and success of
the Company's drilling activities, the volatility of prices and supply and
demand for oil and gas, the numerous uncertainties inherent in estimating
quantities of oil and gas reserves and actual future production rates and
associated costs, the usual hazards associated with the oil and gas industry
(including blowouts, cratering, pipe failure, spills, explosions and other
unforeseen hazards), and increases in regulatory requirements, some of which
risks (as well as others) are described more fully elsewhere in this Form 10-K.

      All forward-looking statements attributable to the Company or persons
acting on its behalf are expressly qualified in their entirety by such factors.

Oil and Gas Exploration and Production

      All of the Company's exploration and production activities are located
within the United States. The Company competes with major oil and gas companies,
other independent oil and gas concerns and individual producers and operators in
the areas of reserve acquisitions and the exploration, development, production
and marketing of oil and gas, as well as contracting for equipment and hiring of
personnel. Oil and gas prices have historically been volatile and are expected
to continue to be volatile in the future. Prices for oil and gas are subject to
wide fluctuation in response to relatively minor changes in the supply of and
demand for oil and gas, market uncertainty and a variety of additional factors
that are beyond the Company's control. These factors include political
conditions in the Middle East and elsewhere, the foreign supply of oil and gas,
the price of foreign imports, the level of consumer product demand, weather
conditions, domestic and foreign government regulations and taxes, the price and
availability of alternative fuels and overall economic conditions.

      One customer, Tennessee Gas, accounted for less than 3%, 5% and 40% of the
Company's consolidated revenue for the years ended December 31, 1998, 1997 and
1996, respectively. No other single customer accounted for more than 10% of the
Company's annual consolidated revenues in the three years ended December 31,
1998.

Development and Production Activities

      During the three-year period ended December 31, 1998, the Company
participated in drilling 294 gross wells, of which 71% were successful. In 1998
the Company participated in the drilling of 74 wells, of which 69% were
successful. This included 55 development wells and 19 exploration wells with
success rates of 76% and 47%, respectively. Noteworthy discoveries include a
well in the West Shugart Field in the Mid-Continent Region and a well in the
North Clara Field in the Onshore Gulf Coast Region, each of which has
significant offset potential.

      In the fourth quarter of 1998 the Company began selectively curtailing its
capital program to conserve cash and reduce debt. Based on depressed commodity
prices and reduced capital availability, the Company intends to concentrate its
1999 capital drilling program on lower risk stepout and extension wells in the
Mid-Continent Region and medium-risk exploration wells with higher reserve
potential in the Gulf Coast Region.

      The Company's policy is to commit no more than 25% of its cash flow to
exploration activities and generally no more than $750,000 for any single
exploratory well. The Company intends to participate in drilling a variety of
prospects, including both low-risk and medium-risk, higher-potential prospects
in order to maintain a balanced program with the potential for significant
reserve additions.

Volumetric Production Payment Program

      The Company augments its working interest ownership of properties with a
VPP Program, a method of acquiring oil and gas reserves scheduled to be
delivered in the future at a discount to the current market price in exchange
for an up-front cash payment. A VPP entitles the Company to a priority right to
a specified volume of oil and gas reserves scheduled to be produced and
delivered over a stated time period. Although specific terms of the Company's
VPPs vary, the Company is generally entitled to receive delivery of its
scheduled oil and gas volumes at agreed delivery points, free of drilling and
lease operating costs and, in certain cases, free of state severance taxes. The
Company believes that its VPP Program diversifies its reserve base and achieves
attractive rates of return while minimizing the Company's exposure to certain
development, operating and reserve volume risks. Typically, the estimated proved
reserves of the properties underlying a VPP are substantially greater than the
specified reserve volumes required to be delivered pursuant to the production
payment.

      Since the inception of the VPP Program in August 1994 through December 31,
1998, the Company had invested $195.8 million under the VPP Program and had
acquired proved reserves of 115.3 Bcfe of natural gas and oil. The Company has
recovered approximately $128.6 million in revenue from the sale of oil and gas
acquired under the program, with 49.0 Bcfe of natural gas and oil scheduled for
future deliveries.

Raw Materials

      The Company obtains its raw materials (principally natural gas and oil)
from various sources, which are presently considered adequate. While the Company
regards the various sources as important, it does not consider any one source to
be essential to its business as a whole.

Patents and Licenses

      There are no patents, trademarks, licenses, franchises or concessions held
by the Company, the expiration of which would have a material adverse effect on
its business.

Seasonality

      Demand for natural gas and oil is seasonal, principally related to weather
conditions and access to pipeline transportation.

Regulation

      General. The Company's business is affected by numerous governmental laws
and regulations, including energy, environmental, conservation, tax and other
laws and regulations relating to the energy industry. Changes in any of these
laws and regulations could have a material adverse effect on the Company's
business. In view of the many uncertainties with respect to current and future
laws and regulations, including their applicability to the Company, the Company
cannot predict the overall effect of such laws and regulations on its future
operations.

      The Company believes that its operations comply in all material respects
with all applicable laws and regulations and that the existence and enforcement
of such laws and regulations have no more a restrictive effect on the Company's
method of operations than on other similar companies in the energy industry.

      The following discussion contains summaries of certain laws and
regulations and is qualified in its entirety by the foregoing.

      State Regulations Affecting Production Operations. The Company's
exploration, production and exploitation activities are subject to regulation at
the state level. Such regulation varies from state to state, but generally
includes requiring permits for the drilling of wells, maintaining bonding
requirements to drill or operate wells, and regulating the location of wells,
the method of drilling and casing wells, the surface use and restoration of
properties upon which wells are drilled, the plugging and abandoning of wells,
and the disposal of fluids used in connection with operations. The Company's
operations are also subject to various state conservation laws and regulations.
These include regulation of the size of drilling and spacing units or proration
units, the density of wells which may be drilled, and the unitization or pooling
of oil and gas properties. In addition, state conservation laws 


                                       3
<PAGE>   5

establish maximum rates of production from oil and gas wells, restrict the
venting or flaring of gas and impose certain requirements regarding the
ratability of production. These regulations and requirements may affect the
profitability of affected properties or operations, and the Company is unable to
predict the future cost or impact of complying with such regulations.

      Regulations Affecting Sales and Transportation of Oil and Gas. Various
aspects of the Company's oil and gas operations are regulated by agencies of the
federal government. The Federal Energy Regulatory Commission (the "FERC")
regulates the transportation of natural gas in interstate commerce pursuant to
the Natural Gas Act of 1938 (the "NGA") and the Natural Gas Policy Act of 1978
(the "NGPA"), including natural gas produced or marketed by the Company. In the
past, the federal government has regulated the prices at which the Company's
natural gas could be sold. Currently, "first sales" of natural gas by producers
and marketers, and all sales of crude oil, condensate and natural gas liquids,
can be made at uncontrolled market prices, but Congress could reenact price
controls at any time.

      Commencing in April 1992, the FERC issued its Order No. 636 and related
clarifying orders ("Order No. 636") which, among other things, restructured the
interstate natural gas industry and required interstate pipelines to provide
transportation services separate, or "unbundled," from the pipelines' sales of
natural gas. Order No. 636 and certain related "restructuring proceedings"
affecting individual pipelines were the subject of a number of judicial appeals
and orders on remand by the FERC. Order No. 636 has largely been upheld on
appeal. The FERC continues to address Order 636-related issues (including
transportation capacity auctions, alternative and negotiated ratemaking, policy
matters affecting gas markets and gas industry standards) in a number of pending
proceedings. The FERC continues to examine its policies affecting the natural
gas industry. It is not possible for the Company to predict what effect, if any,
the ultimate outcome of the FERC's various initiatives will have on the
Company's operations.

      Order No. 636 was issued to foster increased competition within all phases
of the natural gas industry. Although Order No. 636 has provided the Company
with increased access to markets and the ability to utilize new types of
transportation services, the Company is required to comply with pipeline
operating tariffs, including restrictive pipeline imbalance tolerances, and to
respond to penalties for violations of those tariffs. The Company believes that
Order No. 636 has not had any significant impact on the Company.

      The FERC continues to authorize the sale and abandonment from NGA
regulation of natural gas gathering facilities previously owned by interstate
pipelines. Such facilities (and services on such systems) may be subject to
regulation by state authorities in accordance with state law. A number of states
have either enacted new laws or are considering the inadequacy of existing laws
affecting gathering rates and/or services. For example, the Texas Railroad
Commission has recently issued a code of conduct governing transportation and
gathering services provided by intrastate pipelines and gatherers and affirmed
that services are to be provided to shippers without undue discrimination. Other
states have implemented specific regulations covering gathering services. In
general, state regulation of gathering facilities generally includes various
safety, environmental, and in some circumstances, nondiscriminatory take
requirements, but does not generally entail regulation of the gathering rates
charged. Natural gas gathering may receive greater regulatory scrutiny by state
agencies in the future, and in that event, the Company's gathering operations
could be adversely affected; although the Company does not believe that it would
be affected by such regulation any differently than other natural gas producers
or gatherers. The effects, if any, of changes in existing state or FERC policies
on the Company's gas gathering or gas marketing operations are uncertain.

      Sales of crude oil, condensate and natural gas liquids by the Company are
not currently regulated and are made at market prices. The price the Company
receives from the sale of these products is affected by the cost of transporting
the products to market. Effective as of January 1, 1995, the FERC implemented
regulations establishing an indexing system for transportation rates for oil
pipelines, which generally index such rates to inflation, subject to certain
conditions and limitations. The Company is not able to predict with certainty
what effect, if any, these regulations will have on it, but other factors being
equal, the regulations may tend to increase transportation costs or reduce
wellhead prices under certain conditions.

      Federal regulations affecting production operations. The Company also
operates federal and Indian oil and gas leases, which are subject to the
regulation of the United States Bureau of Land Management ("BLM"), the Bureau of
Indian Affairs ("BIA") and/or the United States Minerals Management Service
("MMS").


                                       4
<PAGE>   6

      MMS, BIA and BLM leases contain relatively standardized terms requiring
compliance with detailed regulations and, in the case of offshore leases, orders
pursuant to the Outer Continental Shelf Lands Act ("OCSLA") (which are subject
to change by the MMS). Such regulations specify, for example, lease operating,
safety and conservation standards, as well as well plugging and abandonment and
surface restoration requirements. To cover the various obligations of lessees of
federal and Indian lands, including lessees of Outer Continental Shelf ("OCS")
lands, the BIA, BLM and the MMS generally require that lessees post bonds or
other acceptable assurances that such obligations will be met. The cost of such
bonds or other surety can be substantial and there is no assurance that any
particular lease operator can obtain bonds or other surety in all cases. Under
certain circumstances, the MMS, BIA or BLM may require operations on federal or
Indian leases to be suspended or terminated. Any such suspension or termination
could adversely affect the Company's interests. The MMS has issued a notice of
proposed rulemaking in which it proposes to amend its regulations governing the
calculation of royalties and the valuation of crude oil produced from federal
leases. This proposed rule would modify the valuation procedures for both arm's
length and non-arm's length crude oil transactions to decrease reliance on oil
posted prices and assign a value to crude oil that better reflects its market
value, establish a new MMS form for collecting differential data, and amend the
valuation procedure for the sale of federal royalty oil. The Company cannot
predict what action the MMS will take on this matter, nor can it predict how the
Company will be affected by any change to this regulation. The MMS continues to
consider changes to the method of calculating royalties on oil and gas produced
from federal leases. For example, the MMS also continues to propose changes to
the way it values natural gas for royalty payments. These proposed changes would
establish an alternative market-based method to calculate royalties on certain
natural gas sold to affiliates or pursuant to non-arm's length sales contracts.
Discussions among the MMS, industry officials and Congress are continuing,
although it is uncertain whether and what changes may ultimately be proposed
regarding gas royalty valuation.

      Additional proposals and proceedings that might affect the oil and gas
industry are pending before Congress, the FERC, the MMS, the BLM, the BIA, state
commissions and the courts. The Company cannot predict when or whether any such
proposals may become effective. Historically, the natural gas industry has been
very heavily regulated. There is no assurance that the current regulatory
approach pursued by various agencies will continue indefinitely into the future.
Notwithstanding the foregoing, it is not anticipated that compliance with
existing federal, state and local laws, rules and regulations will have a
material or significantly adverse effect upon the capital expenditures, earnings
or competitive position of the Company.

      Operating Hazards and Environmental Matters. The oil and gas business
involves a variety of operating risks, including the risk of fire, explosions,
blowouts, pipe failure, casing collapse, abnormally pressured formations and
environmental hazards such as oil spills, natural gas leaks, ruptures and
discharge of toxic gases, the occurrence of any of which could result in
substantial losses to the Company due to injury or loss of life, severe damage
to or destruction of property, natural resources and equipment, pollution or
other environmental damage, cleanup responsibilities, regulatory investigation
and penalties and suspension of operations. Although the Company believes it is
adequately insured, such hazards may hinder or delay drilling, development and
on-line production operations.

      Oil and gas operations are subject to extensive federal, state and local
laws and regulations that regulate the discharge of materials into the
environment or otherwise relate to the protection of the environment. These laws
and regulations may require the acquisition of a permit before drilling
commences; restrict or prohibit the types, quantities and concentration of
substances that can be released into the environment or wastes that can be
disposed of in connection with drilling and production activities; prohibit
drilling activities on certain lands lying within wetlands or other protected
areas; and impose substantial liabilities for pollution resulting from drilling
and production operations. Failure to comply with these laws and regulations may
also result in civil and criminal fines and penalties.

      The Company's properties and any wastes generated by the Company that may
have been disposed thereon or on other lands may be subject to federal or state
environmental laws that could require the Company to remove the wastes or
remediate contamination. For example, the Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA"), also known as the "Superfund" law,
imposes liability, without regard to fault or 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. Under
CERCLA, such persons may be subject to joint and several liability for the costs
of cleaning up the hazardous 


                                       5
<PAGE>   7

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 damage allegedly caused by the release of hazardous
substances.

      In addition to obligations arising under federal and state environmental
laws, the Company may be subject to environmental responsibilities arising under
its oil and gas leases or other contracts. For example, soil contamination and
possible groundwater contamination exist on properties in the Newhall-Potrero
Field in California acquired by the Company in the Medallion Acquisition when it
acquired InterCoast Oil and Gas Company, InterCoast Gas
Services Company, and GED Energy Services, Inc. (collectively "InterCoast"). The
surface landowner has notified the Company and some prior operators of the
Newhall-Potrero Field properties that the landowner expects them to remediate
any contamination. The successor to one of the prior operators in the field, has
in the past performed some remediation of contamination in the field. However,
the additional remediation demanded by the surface landowner is estimated to
cost between $4 million and $47 million, with the most probable costs ranging
between $5 million and $14 million. InterCoast had been indemnified for 100% of
the cost of remediation and restoration activities at the properties by the
company from which it acquired the properties, and the Company believes that it
is a valid successor to InterCoast's indemnity. In addition, the Company
received an indemnity from the owners of InterCoast (InterCoast Energy and
affiliated entities) for 90% of any costs the Company is required to incur in
relation to remediation and restoration activities at the Newhall-Potrero Field.
This indemnity was guaranteed by MidAmerican Capital Company and it covers
environmental claims that are filed against the Company before January 2, 1999.
Given the indemnities available to the Company with respect to this matter,
management does not expect the Company to incur any material environmental costs
in connection with historical contamination in the Newhall-Potrero Field.

      Also, the Company's operations may be subject to the Clean Air Act ("CAA")
and comparable state and local requirements. Amendments to the CAA were adopted
in 1990 and contain provisions that may result in the gradual imposition of
certain pollution control requirements with respect to air emissions from the
operations of the Company. The EPA and states have been developing regulations
to implement these requirements. The Company may be required to incur certain
capital expenditures in the next several years for air pollution control
equipment in connection with maintaining or obtaining permits and approvals
addressing other air emission-related issues. The Company does not believe,
however, that its operations will be materially adversely affected by any such
requirements.

      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. Such financial assurances may
be increased to as much as $150 million if a formal assessment indicates such an
increase is warranted.

      Operations of the Company are also subject to the federal Clean Water Act
("CWA") and analogous state laws. The Company may be required to incur certain
capital expenditures in the next several years in order to comply with
prohibitions against the discharge of produced waters into coastal waters or
increase operating expenses in connection with offshore operations in coastal
waters. Pursuant to other requirements of the CWA, the EPA has adopted
regulations concerning discharges of storm water runoff. This program requires
covered facilities to obtain individual permits, participate in a group permit
or seek coverage under an EPA general permit. While certain of its properties
may require permits for discharges of storm water runoff, the Company believes
that it will be able to obtain, or be included under, such permits, where
necessary, and make minor modifications to existing facilities and operations
that would not have a material effect on the Company. Additionally, pursuant to
other provisions of the CWA, the EPA has adopted regulations concerning
permitting and operations of underground injection control ("UIC") wells,
including such wells used in enhanced recovery and disposal operations
associated with exploration and production activities. The United States
Department of Justice has alleged that certain of the Company's UIC wells in
Toole and Liberty counties, Montana in the Rocky Mountain Region have not
complied with such regulations in certain instances. The Company believes that
resolution of these allegations will not have a material adverse effect on the
Company.


                                       6
<PAGE>   8

      In addition, the disposal of wastes containing naturally occurring
radioactive material which are commonly generated during oil and gas production
is regulated under state law. Typically, wastes containing naturally occurring
radioactive material can be managed on-site or disposed of at facilities
licensed to receive such waste at costs that are not expected to be material.

Employees

      The Company and its subsidiaries employed a total of 210 persons on
December 31, 1998, and has since announced operational consolidations and
additional cost reduction programs which will reduce the number of employees
during 1999.

      Set forth below are descriptions of certain of the Company's significant
oil and gas producing properties and those targeted for significant drilling
activity in 1999. There can be no assurance that any of the wells proposed to be
drilled will be completed, or if completed, will be economically viable.

Mid-Continent Region

Overview

      The Mid-Continent Region is primarily comprised of producing properties
in the Anadarko, Ardmore, Arklatex, Arkoma, Michigan and Permian Basins. The
Company views the Mid-Continent region as providing a solid base of production
replacement and plans to continue to exploit areas within the various basins
that require additional wells for adequate reserve drainage and to drill
low-risk exploration wells. These wells are generally stepout and extension type
wells with moderate reserve exposure. The Company endeavors to be the operator
when it holds a working interest of greater than 50%.

      Estimated proved reserves in the Mid-Continent Region were 135.1 Bcfe as
of December 31, 1998 representing approximately 44% of the Company's reserves.
During the year ended December 31, 1998, in this Region the Company participated
in drilling 41 gross (19.8 net) development wells and 8 gross (4.8 net)
exploratory wells with a completion success rate of 78% and 50%, respectively.
At December 31, 1998, the Company owned leasehold interests within the
Mid-Continent Region covering approximately 315,313 gross (180,061 net) acres.

Description of the Mid-Continent Properties

Sawyer Canyon and Sonora Fields, West Texas

      The Company's holdings in the Sawyer Canyon Field are located in Sutton
County, Texas. The Company owns interests in 342 gross (308 net) wells, of which
it operates 331 gross (299 net) wells. The Company's average working interest in
this field was 90%, and its leasehold position at December 31, 1998 consisted of
approximately 36,900 gross (36,100 net) acres. The main producing formation in
the Sawyer Canyon Field is the Canyon sandstone at a depth of approximately
5,500 feet. These Canyon reservoirs tend to be discontinuous and generally
exhibit lower porosity and permeability, characteristics which reduce the area
that can be effectively drained by a single well to units as small as 40 acres.

      The Company's proved reserves attributable to the Sawyer Canyon Field at
December 31, 1998 are 94% proved developed. The Company currently plans to drill
up to ten additional locations to exploit the remaining proved undeveloped
reserves. The Company also believes that additional reserves may ultimately be
attributed to many of the 30 or more, 40-acre drilling locations remaining on
the property. In addition to exploiting these Canyon sand development
opportunities, the Company intends to continue to evaluate portions of the
Sawyer Canyon Field for potential in the shallower Wolfcamp and deeper Strawn
formations which have been found to be productive in the area.

Elm Grove Field, Louisiana

      The Company's reserve holdings in the Elm Grove Field in Bossier Parish,
Louisiana are 84% proved developed. Production from the Elm Grove Field is
primarily natural gas from the Hosston and Cotton Valley formations at depths of
7,000 to 9,600 feet. As of December 31, 1998, the Company owned an interest in
26 gross (23 net) wells, all of which are operated by the Company. The Company's
operated leasehold position consisted of approximately 5,760 gross (5,545 net)
acres. The Company drilled and completed two Cotton Valley wells in 1998. The
Company has identified additional recompletions and potential development well
locations which may be drilled in 1999.

Mayfield / Hayes and Other Niagaran Reef Fields, Michigan

      The Company's Michigan Niagaran Reef trend properties were acquired in
December 1995. The Company acquired a volumetric production payment contract
covering varying interests in 118 wells. The Company also purchased a working
interest in 28 of those wells. Because the producer delivering volumes to the
Company under the volumetric production payment contract failed to reimburse the
Company for operating expenses advanced by the Company, in 1998 the Company
foreclosed on and acquired all of the working interests in the wells. The major
property on which the wells are located is the Mayfield - 28 Field.

Wilburton Field, Oklahoma

      The Company's 1998 activity in the Wilburton Field, Latimer County,
Oklahoma featured the drilling of the prolific Commissioner #14-1 well which is
producing from the Atoka Bullard sand at approximately 10,000 feet in depth. The
Company owns a 69% working interest in and is the operator of this well. Two
more productive wells have recently been drilled to the Bullard in this field
with the Company owning a 10% and a 7% working interest, respectively.
Additional drilling is planned for 1999 to further develop the Atoka sands on
the Company's acreage holdings of 800 gross (235 net) acres.

Mills Ranch Field, Texas

      The Company owns working interests varying from less than 1% to
approximately 25% in 25 producing wells in this Wheeler County, Texas field. The
deep Hunton formation at approximately 20,000 feet in depth has been the primary
producing zone. During the last year, several companies including KCS have been
successfully developing the shallower Granite Wash interval at approximately
11,500 feet in depth with four wells drilled in 1998. The Company plans to
participate in a number of additional wells in 1999 to further develop Granite
Wash reserves on its 7,807 gross (1,850 net) acres in this field.

West Shugart Field, New Mexico

      The Company recently completed a well in the West Shugart Field located in
Eddy County, New Mexico, in which it has a 100% working interest. During an
initial 24-hour test on November 6, 1998, the Shugart Federal #19-1 well flowed
at a rate exceeding 1,000 bbl of oil per day and 230 Mcf of gas per day from the
Bore Springs Dolomite formation at approximately 8,200 feet. Since that time,
the well has been flowing at a restricted steady rate of approximately 230 bbl
of oil per day as dictated by New Mexico regulations. This well also has three
additional potentially productive zones. The Company's acreage
position in this field of 800 gross (778.4 net) acres is sufficient for up
to 19 additional wells.

Newhall-Potrero Field, California

      The Company's Newhall-Potrero Field is located in Los Angeles County,
California, outside the city of Valencia. At December 31, 1998, net proved
reserves were 7,689 MMcfe, all of which were proved developed. The Company is
the operator and owns a 100% working interest in 39 active wells. The Company
has been able to maintain the oil production at or above the same production
rates as the field was producing when it was acquired in 1993 by converting
certain wells from gas lift to pumping unit operations and reworking other
wells. The Company 


                                       10
<PAGE>   12
was also able to reduce the per barrel lifting cost. The Company continues to
pursue other production enhancement opportunities in the Newhall-Potrero Field.

Onshore Gulf Coast Region

Overview

      The Onshore Gulf Coast Region is primarily comprised of producing
properties in south Texas, coastal Louisiana and the Mississippi Salt Basin. The
Company conducts development programs and pursues moderate-risk, higher-exposure
exploration drilling programs. The expanding Onshore Gulf Coast Region has
prospects which are expected to provide the key area of future growth for the
Company. Estimated proved reserves in the region were 72.0 Bcfe as of December
31, 1998, which represented approximately 23% of the Company's reserves.

      During 1998 the Company drilled 5 gross (2.9 net) development wells and 5
gross (2.3 net) exploratory wells in the Onshore Gulf Coast Region. The 1998
success rates were 80% for development wells and 40% for exploratory wells. The
Company owns or controls approximately 153,000 gross (78,000 net) acres in its
Onshore Gulf Coast Region.

Cypress/Langham Creek Field, Texas

      This area is comprised of the Cypress, Cypress Deep and Langham Creek
fields in western Harris County, Texas, where the Company has interests in and
is the operator of 12,726 gross (6,311 net) acres. Multiple horizons in this
area produce oil and gas from Eocene age sandstone in the Yegua formation at
depths of 6,000 to 7,500 feet and in the Wilcox formation at depths of 9,000 to
16,500 feet.

      The Company acquired additional working interests in the Langham Creek
Field in May 1997, which added 14,000 MMcfe of proved reserves. With this, the
Company's third acquisition in the Langham Creek Field, the Company assumed
operatorship and now owns working interests varying from 33% to 87% in 18 wells
in this area. The Company has recently acquired a 3-D seismic survey over the
Langham Creek Field and has completed a comprehensive field study. Five to eight
exploitation wells will be scheduled over the next 18 to 24 months to further
develop this field. Additional reservoir potential will be tested in the deep
Wilcox zones, which were found productive in a 16,500-foot well drilled during
late 1997 on the north flank of the field.

Bob West Field, Texas

      The Company has interests in approximately 862 gross (395 net) acres in
the Bob West Field located in Zapata and Star counties, Texas. The field
produces natural gas from a series of 20 different Upper Wilcox sands with
formation depths ranging from 9,500 to 13,500 feet that require stimulation by
hydraulic fracturing to recover the reserves effectively. Because the majority
of the Bob West Field is situated under Lake Falcon on the Rio Grande River,
most wells were drilled directionally under the lake from common lakeshore drill
sites.

      The Company owns interests in two principal areas in the Bob West Field.
The Company has an effective 12.5% working interest in all production from the
Guerra "A" and Guerra "B" units containing 34 producing wells. The Company also
owns a 100% working interest in 511 acres referred to as the Falcon/Bob West
Field which contains 16 producing natural gas wells.

Dickinson Field, Texas

      The Company has a leasehold position of approximately 1,477 acres
(including 388 fee acres) and operates 22 wells and an eight-inch pipeline in
the Dickinson Field located in Galveston County, Texas. The Company's working
interest in the property is 100% in the producing horizons and its net revenue
interest in various leases ranges from 90.6% to 93.8%. The Dickinson Field
consists of several complex faulted reservoirs that overlie a deep-seated
piercement salt dome. Production occurs from 18 separate Frio reservoirs at
depths between 7,000 and 10,000 feet.

      The Dickinson Field was producing 1,800 Mcf of gas per day and 10 bbl of
oil per day when acquired on April 10, 1998. Since then, the Company has more
than doubled the field production. In December 1998, the Company acquired a 3-D
seismic survey over the field. Additional workover and exploration drilling
opportunities exist in this field.

North Padre Field, Texas

      The Company recently acquired a 75% working interest in approximately 700
gross acres in this field which is located in Kleberg County, Texas.
Re-development of this field to recover low pressure reserves is scheduled for
early 2000 with the drilling of two new wells and the re-entry of an existing
well.

North Clara Field, Mississippi

      The Company owns a 20% working interest in the recently announced
discovery at the North Clara Field in Wayne County, Mississippi. This well was
drilled and completed in the Smackover formation at a depth of 16,500 feet. The
well was placed on production in January 1999 and is currently producing
approximately 3,500 Mcf of gas and 794 barrels of condensate per day with 7,000
pounds of flowing tubing pressure. A 3-D seismic survey covering the Company's
2,300-acre leasehold is currently under way. Additional development wells are
scheduled for this field in late 1999.

      The Company also has a 25% working interest in two other Mississippi Salt
Basin prospects, West Clara and Pool Creek, that encompass approximately 9,000
acres. These prospects have Upper Jurassic, Cotton Valley and Smackover
potential. Several recent discoveries have been made along salt ridges in these
reservoirs. A 3-D survey was shot across the West Clara prospect last year and
the first well for this area will be spudded during 1999.

Glasscock Ranch, Texas

      The Company owns an 89.5% working interest in this field which is located
in Colorado County, Texas. KCS currently has eight active wells in the field and
two additional development locations remain to be drilled.

Rocky Mountain Region

Overview

      In the Rocky Mountain Region, the Company's operations are focused
primarily in the Big Horn Basin in Wyoming. Operationally, this geographic
region reports to the Mid-Continent Division. In mid-1998, because of
particularly low commodity prices in this region, and disappointing drilling
results, the Company curtailed its capital spending program in this area and
implemented a cost-reduction plan which has reduced operating and administrative
expenses. Until commodity prices improve significantly, the Company plans no
substantial development or exploration activity in the Rocky Mountain Region.

      Estimated proved reserves in the Rocky Mountain Region were 49.6 Bcfe as
of December 31, 1998 representing approximately 16% of the Company's reserves.
During 1998, the Company drilled 9 gross (9 net) development wells and 6 gross
(4.8 net) exploratory wells in the Rocky Mountain Region. As of December 31,
1998, the Company owned working interests covering approximately 470,723 gross
(321,747 net) acres in the area, primarily in the Big Horn Basin.

Manderson Field, Wyoming

      The Manderson Field is located in the Big Horn Basin of north central
Wyoming. The field has established production from multiple reservoirs, which
range in depth from 4,500 to 7,800 feet and include the Frontier, Octh Louie,
Muddy, Phosphoria and Tensleep formations.

      Both the Phosphoria and Tensleep formations produce hydrogen sulfide
associated with oil and natural gas. The presence of sour gas and the
limitations imposed by the State of Wyoming created the need for a sour gas
processing facility (amine plant) and an associated acid gas injection system.
The Company's amine plant has the design capacity to treat up to 28,000 Mcf of
sour gas (20% hydrogen sulfide content level) per day to pipeline
specifications. The Company is seeking production from other well operators to
utilize the plant's excess capacity. The other formations in the area produce
relatively sweet oil and natural gas.

      Since acquiring its interest in the field in 1995, the Company has drilled
74 total wells of which 53 were drilled to the Phosphoria formation. The
Company's recent efforts to redevelop the Manderson Field with closer spacing
have resulted in 25 new wells currently producing from the Phosphoria formation.
Twenty-seven wells are currently producing from the other productive formations
listed above. Economic results of this program have been less than expected due
to low oil prices and the stratagraphic nature of the Dolomite zone.

      The Company's holdings in the Manderson area are approximately 60,000
gross (56,405 net) acres as of December 31, 1998. At December 31, 1998, the
Company's proved reserves in the Manderson Field included 1,187 Mbbls of oil and
18,367 MMcf of natural gas representing 8% of the Company's proved reserves.


Dragon Trail Field, Colorado

      The Company owns a 16% working interest in the Dragon Trail Field located
in Rio Blanco County, Colorado. This field produces from the Mancos sand at
approximately 3,000 feet in depth. Several test wells to the shallower Mancos
silt formation are planned in 1999.

Battle Creek Field, Montana

      The Company owns a 45% working interest in the Battle Creek Field in
Blaine County, Montana. This field produces gas from the Eagle formation at
approximately 2,000 feet in depth. The Company plans to continue improving the
deliverability of the field as needed to meet market demands through the use of
hydraulic fracture stimulations. Acreage holdings in this area are approximately
4,500 gross (2,000 net) developed acres with another 6,300 gross (2,800 net)
undeveloped acres.

Fourteen Mile Field, Wyoming

      The Company owns a 100% working interest and an 85.5% net revenue interest
in this field located in Washakie County, Wyoming. The Company's holdings in
this field are approximately 45,300 gross (44,700 net) acres of which
approximately 1,500 gross and net acres have been developed. A geologic study is
under way to better define future development potential.

Gulf of Mexico Region

Overview

      The Gulf of Mexico Region includes assets that can be characterized in
three categories: 1) Working interest properties obtained through the Medallion
Acquisition; 2) Proved reserves acquired through VPP transactions; 3)

Properties originally obtained through VPPs and subsequently converted to
overriding royalty interests. Proved reserves for these properties were
estimated as of December 31, 1998 to be 53.1 Bcfe, representing approximately
17% of the Company's reserves.

Working Interest Properties

      The Company has working interests ranging from 4% to 14% in 12 offshore
fields (including blocks located in the East Cameron, Eugene Island, Ship Shoal,
South Timbalier, Vermilion and West Cameron areas) which are operated by other
companies, primarily Newfield Exploration Company.

Conventional VPPs

      Through a series of VPP transactions, the Company has acquired certain
interests in 12 federal leases off the coasts of Texas and Louisiana. Major
fields include the High Island 303/304, the West Cameron 427 and the South Marsh
Island 17.

Other Offshore Interests

      The Company has acquired interests in eight blocks which are primarily
located in shallow waters offshore from Texas and Louisiana, including Brazos
544, Garden Banks 134, Vermillion 277 and several others, through its VPP
Program. In April 1998, the Company converted its limited-term overriding
royalty VPP to an overriding royalty which covers the entire life of the
properties.

Volumetric Production Payment (VPP)Program

      The Company augments its working interest ownership of properties with its
VPP Program, a method of acquiring proved oil and gas reserves from specified
wells scheduled to be delivered in the future, at a discount to the current
market price, in exchange for an up-front cash payment. Although specific terms
of the Company's volumetric production payments vary, the Company is generally
entitled to receive delivery of its scheduled oil and gas volumes free of
drilling and lease operating costs and, in most cases, free of state severance
taxes. After delivery of the oil and gas volumes, the Company arranges for
further downstream transportation and sells such volumes to available markets.
The Company believes that its VPP Program diversifies its reserve base and
achieves attractive rates of return while minimizing the Company's exposure to
certain development and operating risks. Typically, the estimated proved
reserves of the properties underlying a volumetric production payment are
substantially greater than the specified reserve volumes required to be
delivered pursuant to the production payment.

      Since the inception of the VPP Program in late 1994, the Company had
invested $195.8 million in 25 separate transactions and had acquired proved
reserves of 115.3 Bcfe, consisting of 105.7 Bcf of natural gas and 1,611 Mbbls
of oil. This represents an average net acquisition cost of $1.70 per Mcfe,
without the burden of development and lease operating expenses. Through December
31, 1998, the Company had recovered approximately $128.6 million from the sale
of oil and gas received under its VPP Program. The properties which constitute
the VPP Program are principally located in the Gulf of Mexico.

      During 1998, the Company invested $73.5 million in nine separate VPP
transactions and acquired 41,123 MMcf of natural gas and 338 Mbbls of oil,
located in the Gulf of Mexico.

      Although it has not done so in the past, the Company is exploring the
financing of future VPP acquisitions through joint venture partnerships or
similar arrangements with third parties.

Hedging Activities

      The Company seeks to manage the price risk related to future production of
natural gas by entering into various commodity price swaps, futures contracts
and options on futures contracts. As of December 31, 1998, approximately 12.6
Bcf of 1999 production was hedged at an average price of $2.25 per MMbtu. For
the years 2000 through 2005, a total of approximately 13.8 Bcf are hedged at an
average price of $2.06 per MMbtu.

Oil and Gas Reserves

      All information in this Form 10-K relating to estimates of the Company's
proved reserves is based on reports prepared by KCS and several independent
petroleum engineers. The reports for the KCS Medallion Resources, Inc.; KCS
Mountain Resources, Inc.; KCS Resources, Inc.; and KCS Michigan Resources, Inc.
properties, which collectively represent 100% of the KCS proved reserves on
working interest properties, and 85.4% of total KCS proved reserves at December
31, 1998, were audited by Netherland, Sewell & Associates, Inc. pursuant to the
principles set forth in the Standards Pertaining to the Estimating and Auditing
of Oil and Gas Reserve Information promulgated by the Society of Petroleum
Engineers. The independent reserve engineers' estimates were based upon a review
of production histories and other geologic, economic, ownership and engineering
data provided by the Company or third-party operators.

      The following table sets forth, as of December 31, 1998, summary
information with respect to (1) the estimates of the Company's proved oil and
gas reserves attributable to working interests and (2) the reserve amounts
contracted for pursuant to the agreements relating to VPPs. The present value of
future net revenues in the table should not be construed to be the current
market value of the estimated oil and gas reserves owned by the Company.

</TABLE>

      There are numerous uncertainties inherent in estimating quantities of
proved oil and gas reserves and in projecting future rates of production and
future amounts and timing of development expenditures, including underground
accumulations of crude oil and natural gas that cannot be measured in an exact
manner. The accuracy of any reserve estimate is a function of the quality of
available data and of engineering and geological interpretation and judgment.
Estimates of proved undeveloped reserves are inherently less certain than
estimates of proved developed reserves. The quantities of oil and gas that are
ultimately recovered, production and operating costs, the amount and timing of
future development expenditures, geologic success and future oil and gas sales
prices all may differ from those assumed in these estimates. In addition, the
Company's reserves may be subject to downward or upward revision based upon
production history, purchases or sales of properties, results of future
development, prevailing oil and gas prices and other factors. Therefore, the
present value shown above should not be construed as the current market value of
the estimated oil and gas reserves attributable to the Company's properties.

      In accordance with SEC guidelines, the estimates of future net revenues
from the Company's proved reserves and the present value thereof are made using
oil and gas sales prices in effect as of the dates of such estimates and are
held constant throughout the life of the properties except where such guidelines
permit alternate treatment, including, in the case of natural gas contracts, the
use of fixed and determinable contractual price escalations. Average realized
natural gas prices were $2.15 per Mcf and average realized oil prices were $8.57
per barrel at December 31, 1998. The prices for natural gas and, to a lesser
extent, oil, are subject to substantial seasonal fluctuations, and prices for
each are subject to substantial fluctuations as a result of numerous other
factors. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."

Acreage

      The following table sets forth certain information with respect to the
Company's developed and undeveloped leased acreage as of December 31, 1998. The
leases in which the Company has an interest are for varying primary terms, and
many require the payment of delay rentals to continue the primary term. The
leases may be surrendered by the operator at any time by notice to the lessors,
by the cessation of production, fulfillment of commitments, or by failure to
make timely payments of delay rentals. Excluded from the table are the Company's
interests in the properties subject to volumetric production payments.

Item 7. Management's Discussion and Analysis of Financial Condition and Results
        of Operations.

      The following is a discussion and analysis of the Company's financial
condition and results of operations and should be read in conjunction with the
Company's Consolidated Financial Statements (including the notes thereto)
included elsewhere herein.

General

      Several important developments have had and will continue to have a
significant impact on the Company's financial condition and results of
operations.

      On December 23, 1996, the Company and Tennessee Gas Pipeline Company
("Tennessee Gas") entered into a settlement covering all claims and litigation
related to the above-market, take-or-pay contract (the "Tennessee Gas
Contract"). As part of the settlement, the Tennessee Gas Contract was terminated
effective January 1, 1997, approximately two years prior to its expiration date.
See Note 11 to Consolidated Financial Statements. Prior to its termination, the
Tennessee Gas Contract had a material and positive effect on the Company's gas
revenue, income and cash flow.

      As of December 31, 1996, the Company completed the arrangements for the
Medallion Acquisition (see Note 4 to Consolidated Financial Statements),
effectively doubling its oil and gas reserves and giving it a substantial
presence in the Mid-Continent Region.

      During 1997, the Company sold its principal natural gas transportation
asset, the Texas intrastate pipeline, and its third-party gas marketing
operations, realizing proceeds of $28.5 million and an after-tax gain of $5.4
million. Accordingly, the financial statements included in this annual report
have been restated to reflect the natural gas transportation and marketing
operations as discontinued operations.

      These developments transformed the Company from an enterprise heavily
dependent on the Bob West Field and the Tennessee Gas Contract, with marketing
and transportation operations, to a Company focused on exploration and
production, with a portfolio of properties in four distinct areas: the
Mid-Continent, Onshore Gulf Coast and Rocky Mountain regions and, primarily
through its Volumetric Production Payment Program ("VPP Program"), the Gulf of
Mexico. Production from the Bob West Field, which in 1995 accounted for 72% of
the Company's oil and gas revenues, accounted for less than 3%, 5% and 40% of
total oil and gas revenue in 1998, 1997 and 1996, respectively.

      During 1997 and 1998, as a result of very low prices for natural gas and
crude oil and, in 1998, disappointing performance of certain prospects in the
Rocky Mountain region, the Company has incurred significant losses due primarily
to non-cash ceiling writedowns of its oil and gas assets and the reduction to
zero of the book value of net deferred tax assets. As a result of these
adjustments, the Company has negative stockholders' equity as of December 31,
1998 and has thereby violated certain covenants in its revolving bank credit
agreements. As a consequence, the Company cannot currently borrow under the
revolving credit facilities. The lenders have not declared the principal balance
immediately due and payable as a result of this default, but have the right to
do so at any time. Should this occur, (1) the Company would be unable to pay the
amount due in cash, although the Company believes the lenders to be fully
secured; and (2) the holders of the Company's senior notes and senior
subordinated notes would have the right to declare the principal amount of the
notes ($275 million) immediately due and payable. Absent any acceleration of the
principal balance payment date, the Company believes its cash flow and proceeds
from asset sales should be sufficient to pay its obligations as they are due,
and to conduct its reduced capital expenditure program. See Liquidity and
Capital Resources and Notes 2 and 7 to Consolidated Financial Statements. The
Company's independent public accountants issued a modified report with respect
to the ability of the Company to continue as a going concern, which also
constitutes a default under the revolving bank credit agreements.

      Prices for oil and natural gas are subject to wide fluctuations in
response to relatively minor changes in the supply of and demand for oil and
natural gas, market uncertainty and a variety of additional factors that are
beyond the Company's control. These factors include political conditions in the
Middle East and elsewhere, domestic and foreign supply of oil and natural gas,
the level of consumer demand, weather conditions and overall economic
conditions.

      All references in the following discussion related to earnings per share
are based upon the Company's diluted earnings per share.

Results of Operations for the Years Ended December 31, 1998, 1997 and 1996

Results of Operations

      Net loss for the year ended December 31, 1998 was $296.5 million, or
$10.08 per share, compared to $92.1 million, or $3.19 per share, for the year
ended December 31, 1997. Depressed oil and gas commodity prices since the latter
part of 1997 combined with the performance of certain of the Company's Rocky
Mountain properties in 1998 resulted in significant non-cash ceiling test
writedowns of the Company's oil and gas assets in both 1998 and 1997. Ceiling
test writedowns in 1998 were $268.5 million pretax ($174.5 million after tax)
compared to $165.1 million pretax ($107.3 million after tax) in 1997.
Additionally, in 1998, the Company recorded a non-cash valuation allowance of
$113.9 million ($93.9 million of which relates to the 1998 non-cash ceiling test
writedowns) to reduce to zero the book value of net deferred tax assets. As a
result of these charges, net loss was increased by $288.4 million, or $9.80 per
share. Excluding the effect of the non-cash asset writedowns, the Company's net
loss was $8.1 million, or $0.28 per share in 1998 compared to income of $9.9
million, or $0.35 per share, in 1997. An 11% increase in oil and gas production
during 1998 was more than offset by the impact of significantly lower energy
prices and higher net interest costs. In 1997, income from discontinued
operations was $5.3 million, or $0.18 per share, which was primarily
attributable to the net gain on disposition of the Company's natural gas
transportation and marketing operations.

      Net loss for the year ended December 31, 1997 was $92.1 million, or $3.19
per share, compared to net income of $19.9 million, or $0.84 per share, for the
year ended December 31, 1996. Loss from continuing operations was $97.4 million,
or $3.37 per share, for 1997, compared to income of $21.7 million, or $0.92 per
share, for 1996. The loss in 1997 resulted from a non-cash ceiling test
provision of $165.1 million pretax ($107.3 million after tax). Excluding the
effect of the ceiling test provision, income from continuing operations in 1997
was $9.9 million, or $0.35 per share. Significantly higher oil and gas
production during 1997 was more than offset by the impact of the termination of
the Tennessee Gas Contract, which contributed premium revenue of $32.8 million
in 1996, and higher interest costs. Income from discontinued operations in 1997
was $5.3 million, or $0.18 per share (primarily the net gain on disposition),
compared to a loss of $1.8 million, or $0.08 per share, in 1996.

</TABLE>

      Oil and Gas Production. The Company's oil and gas production during 1998
increased 11% to 60.5 Bcfe, compared to 54.6 Bcfe produced during 1997. Gas
production increased 15% to 50.1 Bcf, which was partially 


                                       20
<PAGE>   22

offset by a decrease in oil and liquids production of 4% to 1,746 Mbbls. The net
production increase was primarily a result of the VPP Program.

      Oil and gas production during 1997 increased 81% to 54.6 Bcfe, compared to
30.1 Bcfe in 1996, primarily due to the Medallion Acquisition.

      Gas Revenue. In 1998, gas revenue decreased $1.0 million to $103.9
million. Production gains of 15% added $13.2 million of gas revenue in 1998. The
production increase was more than offset by a 14% decrease in average realized
gas prices which resulted in a decrease of $14.2 million in gas revenue compared
to the prior year.

      In 1997, gas revenue increased $12.6 million to $104.9 million. Production
gains added $43.8 million of gas revenue in 1997. This increase was partially
offset by the termination of the Tennessee Gas Contract which provided $32.8
million in premium revenue over corresponding spot market prices in 1996.
Average realized price for gas not covered by the Tennessee Gas Contract was
$2.35 per Mcf for the year ended December 31, 1996.

      Oil and Liquids Revenue. In 1998, oil and liquids revenue decreased $13.3
million to $19.6 million. A 38% decrease in average realized oil and liquids
prices for 1998 accounted for approximately $12.5 million of the 1998 decrease
with the remainder attributable to a 4% reduction in production.

      In 1997, oil and liquids revenue increased $17.2 million to $32.9 million,
compared to 1996. Production gains added $18.8 million of oil and liquids
revenue, partially offset by lower average realized prices.

      Other Revenue, net. Other revenue in 1998 included $4.0 million related to
production tax refunds and approximately $2.0 million from certain marketing and
gathering revenues incidental to the Company's oil and gas exploration and
production operations.

      In 1997, other revenue included $2.5 million related to severance tax
settlements in connection with the Tennessee Gas Contract and $1.3 million from
the settlement of a gas sales contract dispute. The remainder of the increase in
1997, compared to 1996, reflected certain marketing and gathering revenues
primarily as a result of the Medallion Acquisition.

Lease Operating Expenses

      Lease operating expenses increased $1.0 million to $30.4 million, or $0.50
per Mcfe, for the year ended December 31, 1998, compared to $29.4 million, or
$0.54 per Mcfe, in 1997. Higher production, full-time operation of the gas
treatment plant in the Rocky Mountain Region and acquisitions in 1998 were the
primary reasons for the 1998 increase. The decrease in the per-Mcfe rate
reflects a higher percentage of production from the VPP Program, which does not
bear any lease operating expenses.

      For the year ended December 31, 1997, lease operating expenses increased
$20.2 million to $29.4 million, or $0.54 per Mcfe, compared to $9.2 million, or
$0.30 per Mcfe, in 1996. Approximately $17.6 million of this increase was
related to the Medallion Acquisition, with the remainder of the increase
primarily due to expanded operations in the Rocky Mountain Region. The increase
in the per-Mcfe rate reflects a lower percentage of production from the VPP
Program in 1997 compared to 1996.

Production Taxes

      Production taxes, which are generally based on a fixed percentage of
revenue, decreased 32% to $4.0 million in 1998, compared to $5.9 million in
1997. Lower oil and gas revenue during 1998 accounted for $1.2 million of the
decrease with the remainder mainly attributable to a lower average production
tax rate.

      Production taxes increased 133% to $5.9 million in 1997, compared to $2.5
million in 1996. In addition to the effect of higher oil and gas revenue during
1997, a larger percentage of that revenue was subject to severance taxes as a
result of the termination of the Tennessee Gas Contract which provided for
reimbursement to the Company of severance taxes on production covered under that
contract.

General and Administrative Expenses

      General and administrative expenses ("G&A") increased $0.6 million to
$11.3 million, or $0.19 per Mcfe, compared to $10.8 million, or $0.20 per Mcfe,
in 1997. This increase reflects administrative activity associated with the 1998
production increases.


                                       21
<PAGE>   23

      For the year ended December 31, 1997, G&A increased $2.9 million to $10.8
million, compared to 1996. This increase reflects the expansion into the
Mid-Continent Region as a result of the Medallion Acquisition and expanded VPP
operations.

Depreciation, Depletion and Amortization

      The Company provides for depletion on its oil and gas properties using the
future gross revenue method. For the year ended December 31, 1998, depreciation,
depletion and amortization ("DD&A") decreased $0.7 million, compared to 1997, to
$59.9 million due primarily to the decrease in oil and gas revenue partially
offset by an increase in the DD&A rate, both of which are the result of the
lower energy prices in 1998.

      For the year ended December 31, 1997, DD&A increased $15.1 million over
1996 to $60.6 million due primarily to the increase in oil and gas revenue.

Writedown of Oil and Gas Properties

      In accordance with the full cost accounting method and procedures
prescribed by the Securities and Exchange Commission ("SEC"), capitalized oil
and gas property costs are limited to the present value of future net revenues
from estimated production of proved oil and gas reserves at current prices,
discounted at 10%, plus the lower of cost or fair value of unproved properties
("SEC PV10 value"). To the extent that the capitalized costs exceed the
estimated SEC PV10 value at the end of any fiscal quarter, such excess costs are
written down with a corresponding charge to income.

      During 1997 and 1998, the Company recorded non-cash ceiling writedowns of
its oil and gas properties mainly due to depressed natural gas and oil commodity
prices and, in 1998, the performance of certain prospects in the Rocky Mountain
region. At December 31, 1997 a $165.1 million pretax writedown was recorded.
Further declines in commodity prices throughout 1998 and into the first quarter
of 1999 resulted in additional writedowns totaling $268.5 million pretax,
including approximately $65 million for price declines subsequent to December
31, 1998. Average realized natural gas prices were $3.54, $2.46 and $2.15 per
Mcf at December 31, 1996, 1997 and 1998, respectively. During the first part of
1999, average realized natural gas prices fell to $1.67 per Mcf. Average
realized oil prices were $22.45, $15.15 and $8.57 per bbl at December 31, 1996,
1997 and 1998, respectively.

      The Company's sour gas processing facility at the Manderson Field, which
was classified as other property, plant and equipment on the balance sheet at
December 31, 1997, was reclassified to oil and gas properties and its net book
value was reduced to fair value of approximately $5 million in connection with
the year-end 1998 ceiling writedown.

      Further price declines, if not offset by increases in proved oil and gas
reserves, could result in future ceiling writedowns.

Interest Expense

      Interest expense was $35.8 million in 1998, compared to $21.9 million in
1997. This increase reflects higher average borrowings related to the expansion
of the Company's oil and gas operations slightly offset by lower average
interest rates.

      Interest expense increased $7.8 million to $21.9 million for the year
ended December 31, 1997, compared to the same period in 1996. Higher average
borrowings in 1997 due to the expansion of the Company's operations (including
the Medallion Acquisition, the VPP Program and the development of the Manderson
Field) were offset in part by lower average interest rates during the period.

Income Taxes

      Income tax expense was $16.0 million in 1998, which reflected the
establishment of a valuation allowance to reduce to zero the book value of net
deferred tax assets. Due to the significant losses recorded in 1998 and the
uncertainty of future oil and natural gas commodity prices, management has
concluded that this valuation allowance is required in accordance with SFAS 109.
In making its assessment, management considered several factors, including the
uncertainty in the Company's ability to generate sufficient income in order to
realize its future tax benefits, and concluded that the Company can no longer
consider the realization of its net deferred tax assets "more likely than not."

      In 1997 the income tax benefit was $52.1 million compared to income tax
expense of $12.7 million in 1996. See Note 9 to the Consolidated Financial
Statements for the reconciliation of the statutory federal income tax rate to
the Company's effective tax rates.

Liquidity and Capital Resources

Financial Covenant Violation and Continuation as a Going Concern

      During 1998, due to very low prices for natural gas and crude oil and
disappointing performance of certain of the Company's Rocky Mountain prospects,
the Company incurred significant losses, due primarily to $268.5 million of
pretax non-cash ceiling writedowns of its oil and gas assets and a reduction
from $113.9 million ($93.9 million of which relates to the 1998 non-cash ceiling
test writedowns) to zero in the book value of net deferred tax assets. As a
result of these charges, net loss was increased by $288.4 million, or $9.80 per
share. Also, as a result of these adjustments, the Company had negative 
stockholders' equity of $154.2 million as of December 31, 1998 and has violated
certain covenants in its revolving credit agreements. The Company's budget for
development and exploration has been significantly reduced for 1999, due to the
drop in oil and natural gas prices, the related substantial reduction in the
Company's net worth and the resultant default in the tangible net worth
covenants under the Company's revolving credit facilities. While the Company had
planned a capital expenditure program of $60-$90 million, such program is likely
to be reduced by as much as 50% absent a significant rebound in commodity prices
or the sale of assets substantially in excess of currently projected levels.

      Available funding for capital expenditures has been reduced materially
because the Company's net worth is less than required under the Company's two
revolving bank credit facilities, which are therefore in default. While this
default continues, the Company cannot borrow under the credit facilities. The
lenders have not declared the principal balance under the credit facilities
immediately due and payable, but have the right to do so at any time. Should
this occur, (1) the Company would be unable to pay the amount due in cash,
although the Company believes the lenders to be fully secured, and (2) the
holders of the Company's senior notes and senior subordinated notes would have
the right to declare the principal amount of the notes ($275 million)
immediately due and payable. The Company has requested a waiver of the defaults
from the banks. However, there can be no assurance that a waiver will be
granted, or for what period of time. Absent acceleration of the principal
balance of the revolving bank credit facilities, however, the Company believes
its cash flow from operations and projected asset sales should be sufficient to
pay its obligations as they become due and to carry out its reduced capital
expenditure program until at least December 31, 1999, assuming no further
deterioration in current oil and natural gas prices.

      The lenders have also indicated their intention at some time in the near
future to reduce the borrowing base under the revolving bank credit facilities.
The Company is negotiating the amount of the reduction and the terms of payment
of the principal amount which is to be repaid as a result of the reduction. The
required principal payments will place an added burden on cash flow. There are
no assurances that the amount of the borrowing base reduction or the terms of
repayment acceptable to the lenders will be able to be satisfied from the
Company's cash flow. If not, the failure to make the required principal
repayments when due will also constitute a default under the revolving bank
credit facilities.

      As a result of the above factors, there is substantial doubt about the
company's ability to continue as a going concern. The accompanying financial
statements do not include any adjustment relating to the recoverability and
classification of the asset carrying amounts or the amounts and classifications
of liabilities that might result should the company be unable to continue as a
going concern. The Company's independent public accountants issued a modified
report with respect to the ability of the Company to continue as a going
concern. The Company believes that its cost and capital reduction initiatives,
cash flow from operations and the proceeds from assets sales should be
sufficient to meet its short-term interest obligations and operating
requirements. There can be no assurance that, given the Company's limited
capital resources, it can continue to maintain its current production levels
through oil and gas reserve replacement.

      To improve its financial situation, the Company has implemented or intends
to implement the following: 1) Reduce originally planned 1999 capital
expenditures; 2) Negotiate property sales, which are targeted to raise cash
proceeds of approximately $25 million in 1999; 3) Reduce the Company's Rocky
Mountain Region workforce by approximately 60%; 4) Close the Company's New
Jersey corporate office effective May 1, 1999 and transfer all functions to its
Houston, Texas facility, and 5) Implement a salary freeze for senior management.
The Company has engaged a financial advisor to explore strategic alternatives
for financing its activities going forward. The Company also is considering the
formation of partnerships with third-party investors to fund the VPP Program.

Cash Flow From Operating Activities

      Net cash provided by operating activities was $44.0 million during 1998,
compared to $100.2 million for 1997. Net income adjusted for non-cash charges
decreased to $53.1 million for the year ended December 31, 1998, compared to
$77.6 million in 1997. The decrease reflects higher interest costs and the
depressed oil and gas prices which more than offset an 11% increase in
production. The remainder of the reduction in 1998 cash flow from operating
activities, compared to 1997, was largely attributable to the 1997 timing of
cash receipts and disbursements of the discontinued marketing and transportation
operations.


                                       23
<PAGE>   25

      Net cash provided by operating activities was $100.2 million in 1997
compared to $121.3 million in 1996. Net income adjusted for non-cash charges was
$77.6 million for the year ended December 31, 1997, compared to $75.8 million in
1996. The reductions in trade accounts receivable ($51.8 million) and in
accounts payable and accrued liabilities ($34.1 million) in 1997 were largely
related to the discontinuance of the natural gas transportation and marketing
operations, offset by increases due to the overall growth of the Company's
operations. The 1996 period included the receipt of approximately $70 million
from Tennessee Gas for past underpayments and interest.

Investing Activities

      Capital expenditures for the year ended December 31, 1998 were $165.5
million, of which $66.8 million was for development drilling; $73.5 million for
the acquisition of proved reserves under the Company's VPP Program; $23.1
million for lease acquisitions, seismic surveys and exploratory drilling, and
$2.1 million for other assets.

      Capital expenditures in 1997 were $226.6 million, of which $107.4 million
was for development drilling; $49.5 million for the purchase of proved reserves
under the Company's VPP Program; $54.3 million for lease acquisitions, seismic
surveys and exploratory drilling and $15.4 million for other assets.

      During 1997, the Company sold its principal natural gas transportation
asset and its third-party gas marketing operations realizing proceeds of $28.5
million, which were used to reduce indebtedness under its bank credit
facilities, and an after-tax gain of $5.4 million.

      Capital expenditures in 1996 were $282.2 million, of which $183.1 million
was related to the Medallion Acquisition (see Note 4 to the Consolidated
Financial Statements), $54.9 million to development drilling, $15.9 million for
the purchase of oil and gas reserves under the Company's VPP Program and $18.2
million to lease acquisitions, seismic surveys and exploratory drilling.

Debt Financing

      On January 15, 1998, the Company completed a public offering of $125
million senior subordinated notes at an interest rate of 8.875% due January 15,
2008. The net proceeds of approximately $121 million were used to pay down
borrowings under the Company's bank credit facilities.

Credit Facility

      The Company's revolving credit facility ("Credit Facility"), which matures
on September 30, 2000, is used for general corporate purposes, including working
capital and to support the Company's capital expenditure program. On December
31, 1998, the borrowing base, or actual availability under the Credit Facility,
was $75 million. The borrowing base is reviewed at least semiannually and may be
adjusted based on the lenders' valuation of the borrowers' oil and gas reserves
and other factors. The borrowing base is currently under review based upon a
reserve report as of December 31, 1998. Substantially all of the
Company's oil and gas reserves (excluding those pledged under the Revolving
Credit Agreement) have been pledged to secure the Credit Facility.

      The Credit Facility permits the borrowers to choose interest rate options
based on the bank's prime rate or LIBOR and from maturities ranging up to 12
months. The applicable spread over the prime rate or LIBOR is based on the
percentage of the borrowing base outstanding. A commitment fee ranging between
0.375% and 0.50% is paid on the unused portion of the borrowing base. The
weighted average effective interest rate during 1998 was 7.27%. As of December
31, 1998, the weighted average interest rate under the Credit Facility was 7.67%
and $55.7 million was outstanding. The Company is in default under the Credit
Facility. See "Financial Covenant Violation and Continuation as a Going
Concern."

Revolving Credit Agreement

      Simultaneous with the consummation of the Medallion Acquisition, the
Company entered into a revolving credit agreement ("Revolving Credit Agreement")
with a group of banks which will mature on September 30, 2000. The Revolving
Credit Agreement is used for general corporate purposes, including working
capital and to support the Company's capital expenditure program. As of December
31, 1998, the Revolving Credit Agreement had a borrowing base of $90 million.
The borrowing base is reviewed at least semiannually and may be adjusted based
on the lenders' valuation of the borrowers' oil and gas reserves and other
factors. The borrowing base is currently under review based upon a reserve
report as of December 31, 1998. The obligations under the Revolving
Credit Agreement are secured by substantially all of the oil and gas reserves
acquired in the Medallion Acquisition, a pledge of the Medallion entities'
common stock and certain VPP assets.


                                       24
<PAGE>   26

      The Revolving Credit Agreement permits the borrowers under this facility
to choose interest rate options based on the bank's prime rate or LIBOR and from
maturities ranging up to 12 months. The applicable spread over the prime
rate or LIBOR is based on the percentage of the borrowing base outstanding. A
commitment fee ranging between 0.375% and 0.50% is paid on the unused portion of
the borrowing base. The weighted average effective interest rate during 1998 was
7.63%. As of December 31, 1998, the weighted average interest rate under the
Revolving Credit Agreement was 7.5% and $80.0 million was outstanding. The
Company is in default under the Revolving Credit Agreement. See "Financial
Covenant Violation and Continuation as a Going Concern."

Year 2000 Issue

      The Year 2000 problem concerns the possible inability of certain
information systems, primarily computer software programs, to properly recognize
date - sensitive information beginning January 1, 2000 and the related data
processing errors and resulting business problems that this may cause. The
Company has a Year 2000 program in place to 1) Identify and resolve internal
systems issues, and 2) Identify and plan for potential issues with respect to
external vendors and customers.

Internal Systems

      The Company's planning for the internal systems aspects of the Year 2000
problem is focused on five areas: 1) Communications Hardware and Software; 2)
Information Systems Hardware; 3) Network Operating Systems Software; 4) Back
Office Applications and 5) Core Applications.

Communications Hardware and Software

      Communication software upgrades are needed at several of the Company's
offices. This software is readily replaceable with Year 2000 ready versions. The
Company has plans in place to ensure that these systems are ready by installing
those versions available. It is anticipated that related upgrades will be in
place by the end of the second quarter of 1999.

Information Systems Hardware

      Two servers are scheduled for replacement with Year 2000 - compliant
models. Certain workstation replacements are needed throughout the Company, but
these replacements are minimal and readily available. It is anticipated that
replacements will be in place by the end of the third quarter of 1999.

Network Operating Systems Software

      The Company presently uses Windows NT4 and Windows 95 operating systems
which are not Year 2000 compliant. The Company's plan is to have all
workstations on a Windows 2000 system, which is a Year 2000 - compliant
operating system or, depending on the availability of Windows 2000, will install
vendor - provided patches, by the end of the second quarter of 1999 and
immediate implementation of Windows 2000 upon release.

Back Office Applications

      The Company's two principal Microsoft desktop productivity applications
are not currently Year 2000 compliant but it is anticipated that they will be
upgraded with the vendor release due in early 1999. Certain server applications
such as SMS, SQL Arcserve and Inoculan, which allow the Company to manage data
as well as maintain network integrity, are also not compliant but it is
anticipated that they will be upgraded to Year 2000 readiness using vendor
provided patches by the end of the second quarter of 1999.

Core Applications

      The Company's principal core applications are for reserve engineering and
analysis, production reporting and financial and accounting systems. The reserve
engineering and production reporting applications are currently not Year 2000
ready, but are in the process of being upgraded to Year 2000 ready versions. It
is anticipated that upgrade of the reserve engineering and analysis application
will be completed prior to May 31, 1999 and the production reporting system will
be upgraded in the second quarter of 1999. The Company is in the process of
migrating all of its divisions to a single finance and accounting solution which
is Year 2000 compliant. It is anticipated that migration will be completed by
the end of the second quarter of 1999.


                                       25
<PAGE>   27

      The Company believes that the program outlined above will mitigate its
internal systems risk related to the Year 2000 problem. The incremental costs of
this program in 1998 and 1999 are currently estimated to be between $400,000 and
$600,000 in the aggregate, most of which would have been spent in any event
within the next 18 to 24 months in the continuing process of upgrading
information systems to the latest technology. These costs are being expensed as
incurred except for any major investments in replacement computer hardware or
new application systems projects that are normally capitalized and amortized
over the life of the asset.

External Vendor and Customer Issues

      The Company also relies on the systems capabilities of various vendors and
customers to conduct its business. The Company is presently polling its major
vendors and customers to ensure that they will be Year 2000 compliant on a
timely basis and to develop contingency plans for any disruption in their
services or products that could have a significant adverse impact on the
Company's business. These activities are intended to provide a means of managing
risk, but cannot eliminate the potential for disruption due to third - party
failure.

      The worst case scenario of non-compliance by third parties is as follows:

      1)    Inability of the operators of certain wells in which the Company
            owns a working interest to report production, bill, collect and
            remit revenues that are due to the Company.

      2)    Inability of pipeline companies and others to which the Company
            sells natural gas to properly meter production, remarket the gas and
            pay the Company as due.

      3)    Inability of the Company's suppliers to schedule and deliver
            equipment to the Company's operated well sites, causing potential
            delays in drilling and development activities and, conceivably,
            other safety and environmental risks.

      Based upon the results of the Company's assessment of third - party Year
2000 risks, it is anticipated that appropriate contingency plans will be
developed, including the use of manual systems and alternate vendors. The
methodology used in the development of the contingency plans, which are expected
to be in place by the end of the third quarter of 1999, is largely dependent
upon the responses received from the Company's vendors and customers as to their
Year 2000 compliance. The Company does not expect these risks to materialize in
any significant manner. However, if Year 2000 failures do occur and are not
corrected on a timely basis or otherwise mitigated by the Company's contingency
plans, they could have a material adverse effect on the results of operations,
liquidity and overall financial condition.

New Accounting Standards

      In June 1998, SFAS 133 "Accounting for Derivative Instruments and Hedging
Activities" was issued. SFAS 133 establishes new accounting rules and
disclosure requirements for most derivative instruments and for hedging related
to those instruments. The Company will adopt this statement effective January 1,
2000 and is currently assessing the initial effects of adoption.


                                       26
<PAGE>   28

Market Risk Disclosure

      The Company has, and may continue to, enter into swaps, futures contracts
and options to manage the price risk associated with the production of natural
gas and liquids. Since these contracts qualify as hedges and correlate to market
price movement of natural gas or liquids, any gains or losses resulting from
market changes will be offset by losses or gains on corresponding physical
transactions.

      These hedging arrangements have the effect of fixing for specified periods
the prices the Company will receive for the volumes to which the hedge relates.
As a result, while these hedging arrangements are structured to reduce the
Company's exposure to decreases in the price associated with the underlying
commodity, they also limit the benefit the Company might otherwise have received
from any price increases associated with the hedged commodity.

      In accordance with Item 305 of Regulation S-K, the Company has elected 
the tabular method to disclose market risk related to derivative financial 
instruments as well as other financial instruments.

      The following table sets forth the Company's natural gas hedged position
at December 31, 1998. At December 31, 1998 the Company did not have any oil
hedges in place. The Company accounts for oil and natural gas futures contracts 
and commodity price swaps in accordance with FASB Statement No. 80 "Accounting 
for Futures Contracts". See Note 1 to the Consolidated Financial Statements 
for a further discussion of the Company's accounting policy related to these 
contracts.

Report of Independent Public Accountants

To KCS Energy, Inc.:

      We have audited the accompanying consolidated balance sheets of KCS
Energy, Inc. (a Delaware Corporation) and subsidiaries as of December 31, 1998
and 1997, and the related statements of consolidated operations, stockholders'
(deficit) equity and cash flows for each of the three years in the period ended
December 31, 1998. These financial statements are the responsibility of the
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 KCS Energy, Inc. and
subsidiaries as of December 31, 1998 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1998 in conformity with generally accepted accounting principles.

      The accompanying consolidated financial statements have been prepared
assuming that the Company will continue as a going concern. As discussed in
Notes 2 and 7 to the consolidated financial statements, the Company has incurred
significant losses due primarily to non-cash ceiling writedowns of its oil and
gas assets, has negative stockholders' equity and has violated certain financial
covenants within its bank credit facilities all of which raise substantial doubt
about its ability to continue as a going concern. Management's plans in regard
to these matters are also described in Note 2. The financial statements do not
include any adjustments relating to the recoverability and classification of 
the asset carrying amounts or the amounts and classifications of liabilities 
that might result should the Company be unable to continue as a going concern.

                        KCS ENERGY, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

      KCS Energy, Inc. is an independent oil and gas company engaged in the
acquisition, exploration, exploitation and production of natural gas and crude
oil.

Basis of Presentation

      The consolidated financial statements include the accounts of KCS Energy,
Inc. and its wholly owned subsidiaries ("KCS" or "Company"). All significant
intercompany accounts and transactions have been eliminated in consolidation.
Certain previously reported amounts have been reclassified to conform to current
year presentation.

      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. The
financial statements have been prepared assuming the Company will continue as a
going concern. As explained in Note 2, there are uncertainties that this will be
the case. The financial statements do not include any adjustments that reflect
these uncertainties.

Cash Equivalents

      The Company considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents.

Futures Contracts

      The Company utilizes oil and natural gas futures contracts and commodity
price swaps for the purpose of hedging the risks associated with fluctuating
crude oil and natural gas prices and accounts for such contracts in accordance
with FASB Statement No. 80 "Accounting for Futures Contracts." These contracts
permit settlement by delivery of commodities and, therefore, are not financial
instruments as defined by FASB Statement Nos. 107 and 119. Changes in the
market value of these transactions are deferred until the gain or loss on the
underlying item is recognized. See Note 10 for further discussion of the
Company's price risk management activities.

Imbalances

      The Company follows the entitlements method of accounting for production
imbalances, where revenues are recognized based on its interest in oil and gas
production from a well. Imbalances arise when a purchaser takes delivery of more
or less production from a well than the Company's actual interest in the
production from that well. The difference between cash received and revenue
recorded is a receivable or payable. Such imbalances are reduced either by
subsequent balancing of over and under deliveries or by cash settlement, as
required by applicable contracts.

Property, Plant and Equipment

      The Company follows the full cost method of accounting, under which all
productive and nonproductive costs associated with its exploration, development
and production activities are capitalized in a country-wide cost center. Such
costs include lease acquisitions, geological and geophysical services, drilling,
completion, equipment and certain general and administrative costs directly
associated with acquisition, exploration and development activities. General and
administrative costs related to production and general overhead are expensed as
incurred.

      The Company provides for depreciation, depletion and amortization of
evaluated costs using the future gross revenue method based on recoverable
reserves valued at current prices. Under accounting procedures prescribed by the
SEC, capitalized oil and gas property costs are limited to the present value of
future net revenues from estimated production of proved oil and gas reserves
discounted at 10%, plus the value of unproved properties. To the extent that the
capitalized costs exceed the estimated present value of future net revenues at
the end of any 


                                       33
<PAGE>   35

fiscal quarter, such excess costs are written down with a corresponding charge
to income. For the years ended December 31, 1998 and 1997, respectively, the
Company recorded $268.5 million and $165.1 million in pretax non-cash ceiling
writedowns of its oil and gas properties. See Note 2 to Consolidated Financial
Statements and "Management's Discussion and Analysis of Financial Condition and
Results of Operations."

      Unevaluated properties and associated costs not currently being amortized
and included in oil and gas properties were $17.7 million and $21.1 million at
December 31, 1998 and 1997, respectively. Such costs relate to projects which
were at such dates undergoing exploration or development activities or in which
the Company intends to commence such activities in the future. The Company will
begin to amortize these costs when proved reserves are established or impairment
is determined.

      Depreciation of other property, plant and equipment is provided on a
straight-line basis over the useful lives of the assets, except for certain
natural gas gathering pipelines which are depreciated based on the estimated
lives of the gas wells served. Repairs of all property, plant and equipment and
replacements and renewals of minor items of property are charged to expense as
incurred.

Income Taxes

      The Company accounts for income taxes in accordance with FASB Statement
No. 109 "Accounting for Income Taxes." Deferred income taxes are recorded to
reflect the future tax consequences of differences between the tax bases of
assets and liabilities and their financial reporting amounts at each year end. A
valuation allowance is recognized if it is anticipated that some or all of a
deferred tax asset may not be realized.

      For income tax purposes, the Company deducts the difference between market
value and exercise price arising from the exercise of stock options. The tax
effect of this deduction which, for financial reporting purposes, is accounted
for as an increase to additional paid-in capital, amounted to $0.5 million, $1.1
million and $0.7 million in 1998, 1997 and 1996, respectively.

Earnings Per Share

      Basic earnings per share were computed by dividing net income by the
weighted average number of common shares outstanding during the year as required
by FASB Statement No. 128 "Earnings per Share". Diluted earnings per share have
been computed by dividing net income by the weighted average number of common
shares outstanding plus the incremental shares that would have been outstanding
assuming the exercise of stock options and stock warrants as applicable. A
reconciliation of shares used for basic earnings per share and those used for
diluted earnings per share is as follows:

Segment Reporting

      In June 1997, SFAS 131 "Disclosures about Segments of an Enterprise and
Related Information" was issued. SFAS 131 requires that the Company disclose
selected information about operating segments in its annual and interim
financial statements, commencing with the fiscal year 1998 financial statements.
The Company operates in one reportable segment, as an independent oil and gas
company engaged in the acquisition, exploration, exploitation and production of
domestic oil and gas properties. The Company's operations are conducted entirely
in the United States. No customer accounted for more than 10% of the
Company's revenues in 1998 and 1997. In 1996, one customer, Tennessee Gas
Pipeline Company accounted for approximately 40% of total revenue.


                                       34

2. Financial Condition

      During 1998, due to very low prices for natural gas and crude oil and
disappointing performance of certain of the Company's Rocky Mountain prospects,
the Company incurred significant losses, due primarily to $268.5 million of
pretax non-cash ceiling writedowns of its oil and gas assets and a reduction
from $113.9 million ($93.9 million of which relates to the 1998 non-cash ceiling
test writedowns) to zero in the book value of net deferred tax assets. As a
result of these charges, net loss was increased by $288.4 million, or $9.80 per
share. Also as a result of these adjustments, the Company has negative
stockholders' equity of $154.2 million as of December 31, 1998 and has violated
certain bank debt covenants in its revolving bank credit agreements. As a
consequence, the Company cannot borrow under the revolving credit facilities. In
addition, the Company's independent public accountants issued a modified report
with respect to the ability of the Company to continue as a going concern which
also constitutes a default under the revolving bank credit agreements. The
lenders have not declared the principal balance immediately due and payable as a
result of this default, but have the right to do so at any time. Should this
occur, (i) the Company would be unable to pay the amount due in cash, although
the Company believes the lenders to be fully secured; and (ii) the holders of
the Company's senior notes and senior subordinated notes would have the right to
declare the principal amount of the notes ($275 million) immediately due and
payable. The Company has requested a waiver of the defaults from the banks.
However, there can be no assurance that a waiver will be granted, or for what
period of time. Absent any acceleration of the principal balance payment date,
the Company believes its cash flow and proceeds from asset sales should be
sufficient to pay its obligations as they are due, and to conduct its reduced
capital expenditure program. As a result of the above factors, there is
substantial doubt about the Company's ability to continue as a going concern.
The accompanying financial statements do not include any adjustment relating to
the recoverability and classification of the asset carrying amounts or the
amounts and classifications of liabilities that might result should the Company
be unable to continue as a going concern. See Management's Discussion and
Analysis of Financial Condition and Results of Operations - Liquidity and
Capital Resources and Notes 1 and 7.

      To improve its financial situation, the Company has implemented or
intends to implement the following: 1) Reduce planned 1999 capital
expenditures; 2) Negotiate property sales, which are expected to raise cash
proceeds of approximately $25 million in 1999; 3) Reduce the Company's Rocky
Mountain region workforce by approximately 60%; 4) Close the Company's New
Jersey corporate office effective May 1, 1999 and transfer all functions to its
Houston, Texas facility, and 5) Implement a salary freeze for senior
management. The Company has engaged a financial advisor to explore strategic
alternatives for financing its activities going forward. The Company also is
considering the formation of partnerships with third-party investors to fund
the VPP Program.

      The Company believes that its cost and capital reduction initiatives, cash
flow from operations and proceeds from asset sales will be sufficient to meet
its short-term interest obligations and operating requirements. There can be no
assurance that, given the Company's limited capital resources, it can continue
to maintain its current production levels through oil and gas reserve
replacement.

3. Discontinued Operations

      During the first quarter of 1997, the Board of Directors approved a plan
to discontinue the Company's natural gas transportation and marketing operations
in order to focus on the core oil and gas exploration and production operations.
During 1997, the Company sold its Texas intrastate natural gas pipeline system
and its third-party natural gas marketing operations, realizing proceeds of
$28.5 million and an after-tax gain of $5.4 million. Income taxes associated
with the discontinued operations were $2.8 million.

      The summarized results of these operations for the years ended 1997 and
1996 is as follows: revenue of $22.0 million and $274.3 million in 1997 and
1996, respectively, and net loss from operations of $0.1 million and $1.8
million in 1997 and 1996, respectively. By December 31, 1997, all assets of the
discontinued operations were disposed of.

      Discontinued operations have not been segregated in the Statements of
Consolidated Cash Flows and, therefore, amounts for certain captions will not
agree with the respective Statements of Consolidated Operations and Consolidated
Balance Sheets.

4. Medallion Acquisition

      As of December 31, 1996, the Company completed the arrangements for the
acquisition of all of the outstanding stock of InterCoast Oil and Gas Company
(formerly Medallion Production Company), GED Energy Services, Inc. and
InterCoast Gas Services Company (collectively referred to as Medallion),
indirect wholly owned subsidiaries of MidAmerican Energy Holdings Company
("MidAmerican"), for a purchase price of approximately $199.1 million,
consisting of a cash payment of $194.1 million and warrants to purchase 870,000
shares of 


                                       35
<PAGE>   37

Common Stock at an exercise price of $22.50 per share and a four-year term (the
"Medallion Acquisition").

      Medallion's principal assets as of December 31, 1996, were proved oil and
gas reserves of 187.5 Bcfe consisting of 140.3 Bcf of natural gas and 7.9 MMbbls
of oil and liquids. The Company also acquired a natural gas gathering system as
well as oil and gas equipment and supplies. The Medallion Acquisition doubled
the Company's reserve and production base at December 31, 1996.

      The Medallion Acquisition was accounted for using the purchase method. The
results of operations for the acquired entity are included in the Company's
consolidated results of operations from the date of acquisition. Pro forma
revenue, net income and basic earnings per share giving effect to the Medallion
Acquisition for the year ended December 31, 1996, as if the transaction had
occurred on January 1, 1996, is $180.1 million, $35.1 million and $1.21,
respectively. Such unaudited pro forma financial data does not purport to be
indicative of the results of operations that would actually have occurred if the
transaction had occurred as presented or that may be obtained in the future.

5. Retirement Benefit Plans

      The Company sponsors a Savings and Investment Plan ("Savings Plan") under
Section 401(k) of the Internal Revenue Code. Eligible employees may contribute
up to 16% of their base salary to the Savings Plan subject to certain IRS
limitations. The Company may make matching contributions, which have been set by
the Board of Directors at 50% of the employee's contribution (up to 6% of the
employee's annual base salary). The Savings Plan also contains a profit-sharing
component whereby the Board of Directors may declare annual discretionary
profit-sharing contributions. Profit-sharing contributions are allocated to
eligible employees based upon their pro-rata share of total eligible
compensation. Employee and profit-sharing contributions are invested at the
direction of the employee in one or more funds or can be directed to purchase
common stock of the Company at fair market value. Company matching contributions
are invested in shares of KCS common stock. Eligible employees vest in both the
Company matching and discretionary profit-sharing contributions over a four-year
period based upon their years of service with the Company. Company contributions
to the Savings Plan were $393,851 in 1998, $420,090 in 1997 and $102,455 in
1996.

6. Stock Option and Incentive Plans

      Under the 1992 Stock Plan, stock options, stock appreciation rights and
restricted stock may be granted to employees of KCS. The 1992 Stock Plan also
provides that bonus stock may be granted to employees.

      The 1994 Directors' Stock Plan provides that each non-employee director be
granted stock options for 2,000 shares annually. This plan also provides that in
lieu of cash, each non-employee director be issued KCS stock with a fair market
value equal to 50% of their annual retainer.

      Each plan provides that the option price of shares issued be equal to the
market price on the date of grant. All options expire 10 years after the date of
grant.

      Restricted shares awarded under the 1992 Stock Plan have a fixed
restriction period during which ownership of the shares cannot be transferred
and the shares are subject to forfeiture if employment terminates. Restricted
stock has the same dividend and voting rights as other common stock and is
considered to be currently issued and outstanding. The cost of the awards,
determined as the fair market value of the shares at the date of grant, is
expensed ratably over the period the restrictions lapse. Restricted stock
totaling 83,550 shares was outstanding under the 1992 Stock plan and the 1994
Directors' Stock Plan at December 31, 1998.

      At December 31, 1998, a total of 121,002 shares were available for future
grants under the 1992 Stock Plan and the 1994 Directors' Stock Plan.

      Under the 1988 KCS Energy, Inc. Employee Stock Purchase Program (the
"Program"), all eligible employees and directors may purchase full shares from
the Company at a price per share equal to 90% of the market value determined by
the closing price on the date of purchase. The minimum purchase is 25 shares.
The maximum annual purchase is the number of shares costing no more than 10% of
the eligible employee's annual base salary, and for directors, 6,000 shares. The
number of shares issued in connection with the Program was 44,661, 14,520 and
15,326 during 1998, 1997 and 1996, respectively. At December 31, 1998, there
were 812,883 shares available for issuance under the Program.

      As permitted under FASB Statement No. 123 "Accounting for Stock-Based
Compensation" ("SFAS 123") 


                                       36
<PAGE>   38

the Company has elected to continue to account for stock-based compensation
under the provisions of APB Opinion No. 25. Had compensation cost for the
following plans been determined consistent with SFAS 123, the impact on the
Company's net income (loss) would have been $2.3 million in 1998, $0.7 million
in 1997 and $0.1 million in 1996. The impact on basic and diluted loss per share
would have been $0.08 in 1998 and $0.02 in 1997. There would have been no effect
on earnings per share in 1996.

      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 in 1998, 1997 and 1996, respectively: risk-free
interest rates of 5.17%, 6.39% and 6.52%; expected dividend yield of 0.00%,
0.46% and 0.33%; expected lives of 4.0 years, 5.6 years and 5.1 years; expected
stock price volatility of 70.0%, 50.1% and 30.0%.

     As required under SFAS 123, a summary of the status of the stock options
under the 1992 Stock Plan and the 1994 Directors' Stock Plan at December 31,
1998, 1997 and 1996 and changes during the years then ended is presented in the
table and narrative below:

Subordinated Notes

      On January 15, 1998, KCS Energy, Inc. (the "Parent") completed a public
offering of $125 million senior subordinated notes at an interest rate of 8.875%
due January 15, 2008 (the "Subordinated Notes"). The Subordinated Notes are
noncallable for five years and are unsecured subordinated obligations of the
Parent. Prior to 


                                       37
<PAGE>   39

January 15, 2001, the Parent may use proceeds from a public equity offering to
redeem up to 33-1/3% of the Subordinated Notes. The subsidiaries of the Parent
have guaranteed the Subordinated Notes on an unsecured subordinated basis. The
net proceeds of approximately $121 million were used to reduce outstanding
indebtedness under the credit agreements discussed below.

      The Subordinated Notes contain certain restrictive covenants which, among
other things, limit the Company's ability to incur additional indebtedness,
require the repurchase of the Subordinated Notes upon a change of control and
restrict the aggregate cash dividends paid to 50% of the Company's cumulative
net income, as defined in the indenture covering the Subordinated Notes, during
the period beginning October 1, 1997. A ceiling writedown is not a charge
against net income as defined in the indenture. As of December 31, 1998, these
covenants prohibit the Company from paying dividends and incurring additional
Indebtedness (as defined in the indenture), except for Permitted Indebtedness
(also as defined in the indenture). Should the lenders under the Company's
revolving bank credit facilities declare the principal balance thereunder
immediately due and payable, this would constitute a default under the terms of
the Subordinated Notes. In that case, the holders of the Subordinated Notes
could have the right to declare the entire principal balance thereof immediately
due and payable.

Senior Notes

      KCS Energy, Inc. has outstanding $150 million principal amount of 11%
senior notes due 2003 issued pursuant to an indenture governing the senior notes
dated January 25, 1996 (the "Senior Notes"). The Senior Notes mature on January
15, 2003 and bear interest at the rate of 11% per annum. The Senior Notes are
redeemable at the option of the Parent, in whole or in part, commencing January
15, 2000, at predetermined redemption prices set forth within the Senior Notes
indenture. The subsidiaries of the Parent have guaranteed the Senior Notes on a
senior unsecured basis.

      The Senior Notes contain certain restrictive covenants which, among other
things, limit the Company's ability to incur additional indebtedness, require
the repurchase of the Senior Notes upon a change of control and restrict the
aggregate cash dividends paid to 50% of the Company's cumulative net income, as
defined in the indenture covering the Senior Notes, during the period beginning
October 1, 1995. A ceiling writedown is not a charge against net income as
defined in the indenture. As of December 31, 1998, these covenants prohibit the
Company from paying dividends and incurring additional Indebtedness (as defined
in the indenture), except for Permitted Indebtedness (also as defined in the
indenture). Should the lenders under the Company's revolving bank credit
facilities declare the principal balance thereunder immediately due and payable,
this would constitute a default under the terms of the Senior Notes. In that
case, the holders of the Senior Notes could have the right to declare the entire
principal balance thereof immediately due and payable.

Revolving Credit Agreement

      Simultaneous with the consummation of the Medallion Acquisition, the
Company entered into a revolving credit agreement ("Revolving Credit Agreement")
with a group of banks which will mature on September 30, 2000. The Revolving
Credit Agreement is used for general corporate purposes, including working
capital and to support the Company's capital expenditure program. As of December
31, 1998, the Revolving Credit Agreement had a borrowing base of $90 million.
The borrowing base is reviewed at least semiannually and may be adjusted based
on the lenders' valuation of the borrowers' oil and gas reserves and other
factors. The borrowing base is currently under review based upon a reserve
report as of December 31, 1998. The obligations under the Revolving Credit
Agreement are secured by substantially all of the oil and gas reserves acquired
in the Medallion Acquisition, a pledge of the Medallion entities' common stock
and certain VPP assets.

      The Revolving Credit Agreement permits the borrowers under this facility
to choose interest rate options based on the bank's prime rate or LIBOR and from
maturities ranging up to twelve months. The applicable spread is based on the
percentage of the borrowing base that is outstanding. A commitment fee ranging
between 0.375% and 0.50% is paid on the unused portion of the borrowing base.
The weighted average effective interest rate during 1998 was 7.63%. As of
December 31, 1998, the weighted average interest rate under the Revolving Credit
Agreement was 7.5% and $80.0 million was outstanding. As of December 31, 1997,
the weighted average interest rate under the Revolving Credit Agreement was 7.4%
and $68.4 million was outstanding. The Company has violated certain covenants of
the Revolving Credit Agreement. Due to these violations and the resultant
contractual rights of the lenders to declare the principal balance due and
payable, the Company has classified these obligations as current. See Note 2.

Credit Facility

      The Company's revolving credit facility ("Credit Facility"), which matures
on September 30, 2000, is used for general corporate purposes, including working
capital and to support the Company's capital expenditure program. On December
31, 1998, the borrowing base, or actual availability under the Credit Facility,
was $75 million. The borrowing base is reviewed at least semiannually and may be
adjusted based on the lenders' valuation of the borrowers' oil and gas reserves
and other factors. The borrowing base is currently under review based upon a
reserve report as of December 31, 1998. Substantially all of the Company's oil
and gas reserves (excluding those pledged under the Revolving Credit Agreement)
have been pledged to secure the Credit Facility.

      The Credit Facility permits the borrowers to choose interest rate options
based on the bank's prime rate or LIBOR and from maturities ranging up to twelve
months. The applicable spread is based on the percentage of the borrowing base
that is outstanding. A commitment fee ranging between 0.375% and 0.50% is paid
on the unused portion of the borrowing base. The weighted average effective
interest rate during 1998 was 7.27%. As of December 31, 1998, the weighted
average interest rate under the Credit Facility was 7.67% and $55.7 million was
outstanding. As of December 31, 1997, the weighted average interest rate under
the Credit Facility was 7.0% and $74.5 million was outstanding. The Company
has violated certain covenants of the Credit Facility. Due to these
violations and the resultant contractual rights of the lenders to declare the
principal balance due and payable, the Company has classified these obligations
as current. See Note 2.

Other Information

     The fair value of the Company's Senior Notes and Subordinated Notes at
December 31, 1998 were $132.0 million and $68.8 million, respectively. These
values were estimated based upon the December 31, 1998 quoted market price of
$88.00 for the Senior Notes and $55.00 for the Subordinated Notes. Subsequent to
year end, the Senior Notes and the Subordinated Notes have traded as low as
$67.00 and $25.00, respectively. The estimated fair value of the Company's
Senior Notes at December 31, 1997 was $165 million based upon the quoted market
price of $110.00 at such date. The carrying amount of the remaining debt at
year-end 1998 and 1997 approximates fair value.

</TABLE>

      Income tax payments were $0.3 million in 1998, $0.5 million in 1997 and
$5.6 million in 1996. Also, in 1998, the Company received a federal income tax
refund of $3.2 million.

      Historically, the Company has recorded tax benefits relating to its pretax
book losses even though it has been in a net operating loss carryforward
position for federal income purposes. SFAS 109 allows for such tax benefits to
be recorded as deferred tax assets if management believes that it is "more
likely than not" that these assets will be realized through the generation of
future taxable income. Due to the significant losses recorded in 1998 and the
uncertainty of future oil and natural gas commodity prices, management has
concluded that a valuation allowance against net deferred tax assets is required
in accordance with SFAS 109. In making its 


                                       40
<PAGE>   42

assessment, management considered several factors, including uncertainty of the
Company's ability to generate sufficient income in order to realize its future
tax benefits. Accordingly, the Company has recorded a valuation allowance of
$113.9 million as of December 31, 1998. The valuation allowance will be
monitored for potential adjustments as future events so indicate.

     Deferred tax assets relate primarily to the Company's pre-tax book losses,
the net operating loss and alternative minimum tax credit carryforwards. At
December 31, 1998, the Company had tax net operating losses ("NOLs") of
approximately $194.8 million available to offset future taxable income of which
approximately $14.5 million will expire in 2011, $82.6 million will expire in 
2012 and $97.7 million in 2018.

10. Financial Instruments

      The Company has entered into swaps, futures contracts and options to
manage risks associated with fluctuations in the price of its natural gas and
oil production.

      Commodity Price Swaps. Commodity price swap agreements require the Company
to make payments to (or entitle it to receive payments from) the counterparties
based upon the differential between a specified fixed and variable price. The
Company accounts for these transactions on a settlement basis and, accordingly,
gains or losses are included in gas revenue in the period in which the
underlying natural gas is produced. These agreements do not impose cash margin
requirements on the Company. At December 31, 1998, the Company was party to
commodity price swap agreements covering approximately 12.6 million MMBtu, 3.5
million MMBtu and 10.4 million MMBtu of natural gas production for the years
1999, 2000 and for the period 2001 through 2005, respectively. Deferred gains,
net of deferred losses, were 1.8 million at December 31, 1998.

      Futures and Options Contracts. Natural gas futures contracts require the
Company to buy or sell natural gas at a fixed price. The Company uses futures to
hedge price risk on a portion of its gas production and to manage profit margins
on offsetting fixed-price purchase or sale commitments for physical quantities
of natural gas. Futures contracts mandate initial margin requirements. The
Company maintains such margin accounts and funds in cash any daily settlement
requirements relating to futures contracts. Natural gas options used to hedge
price risk provide only the right, not the requirement, to buy or sell natural
gas at a fixed price. The Company uses options to limit overall price risk
exposure.

      At December 31, 1998, the Company had no open futures contracts. At
December 31, 1997, the Company's hedging activities consisted of 219 short
contracts at an average price of $2.46 per MMBtu maturing through 1998 covering
2,190 MMBtu of natural gas. Since these contracts qualify as hedges and
correlate to market price movements of natural gas, any gains or losses
resulting from market changes will be offset by losses or gains on corresponding
physical transactions. Deferred gains, net of deferred losses, were $0.5 million
at December 31, 1997.

11. Litigation

Tennessee Gas Litigation

      Prior to January 1, 1997, most of the Company's natural gas sold from the
Bob West Field in south Texas was covered by the Tennessee Gas Contract, which
had been the subject of several lawsuits. On December 23, 1996, the Company and
Tennessee Gas entered into a comprehensive settlement covering all claims and
litigation between them related to the Tennessee Gas Contract. As part of the
settlement, the Tennessee Gas Contract was terminated effective January 1, 1997,
approximately two years prior to its expiration date. The parties also agreed to
the dismissal of the two pending lawsuits that had been filed in Zapata County,
Texas, thereby concluding all matters of litigation between them. The December
1996 settlement did not affect the Company's successful conclusion earlier in
the year of the litigation that was decided by the Texas Supreme Court relating
to the validity and pricing provisions of the Tennessee Gas Contract or the
Company's recovery of $70 million of past underpayments (including interest and
net of severance taxes and other payables related to the contract) that had
accrued under the Tennessee Gas Contract.

Royalty Suits

      The Company is a party to six lawsuits in the Texas State Courts involving
various claims asserted by various holders of royalty interests under leases on
the acreage that was dedicated to the Tennessee Gas Contract or pooled
therewith. One suit involves claims by the holder of an overriding royalty
interest in the dedicated acreage 


                                       41
<PAGE>   43

of certain rights in the Tennessee Gas Contract. Of the other five (the "Royalty
Basis Suits"), one seeks a declaratory judgment on the royalty payment basis for
non-dedicated acreage in which the Company owns no interest. The other four
suits seek declaratory judgments to determine whether royalties payable to the
holders of landowner royalty interests in the dedicated acreage should be based
on the net proceeds received by the Company for gas sales under the Tennessee
Gas Contract or on the spot market price. The Company paid royalties based upon
the spot market price to the holders of royalty interests (other than the
overriding royalty interest) because the Company's leases, which cover only
dedicated acreage, have market value royalty provisions.

      Initially, there were three Royalty Basis Suits, one in Dallas County,
Texas, in which the Company is a co-plaintiff and two subsequently filed suits
in Zapata County, Texas, in which the Company is a co-defendant (the "Las
Blancas Suit" and the "Gonzalez Suit"). The Dallas suit was subsequently split
into four separate lawsuits, based on issues concerning 1) the dedicated
acreage in the Guerra "A" and Guerra "B" Units (the "Los Santos Suit"), 2) the
non-dedicated acreage in those Units (the "Collins Suit"), in which the Company
has no interests, 3) the Jesus Yzaguirre Unit, which consists entirely of
dedicated acreage owned only by the Company (the "Jesus Yzaguirre Suit"), and
4) the overriding royalty interest in the dedicated acreage (the "Matthews
Suit").

      On March 4, 1997, the holder of an overriding royalty interest filed a
claim against the Company and its co-lessees in the Matthews Suit, alleging
breach of duties arising from the termination of the Tennessee Gas Contract and
for certain tortious acts. Effective January 23, 1998, the Company and the
royalty holder settled their disputes. On February 3, 1998, the Company and its
co-lessees were dismissed from the Matthews Suit. In addition, in May 1997, the
Gonzalez Suit was dismissed and in October 1997 the Las Blancas Suit was
dismissed.

      The Los Santos Suit and the Jesus Yzaguirre Suit have resulted in separate
summary judgments in favor of the Company's position that royalty payments based
upon the spot market price are all that is required to be paid under the leases
and granting dismissal of the royalty owners counterclaims and affirmative
defenses. In early 1997, the summary judgment in the Los Santos Suit was
appealed to the Fifth Court of Appeals in Dallas by the royalty holders, who
requested oral argument on 11 points of error. These points of error concern
the granting of summary judgment against them on issues of lease provisions on
market value royalties and on their counterclaims and affirmative defenses of
fraud, negligent misrepresentations, conspiracy and estoppel; for denial of
their efforts to supplement summary judgment evidence; for denial of efforts to
transfer venue to Zapata County; for failure to abate the Dallas lawsuit in
favor of the two suits filed later by them in Zapata County; and for the entry
of final judgment in favor of the Company and its co-plaintiffs. Supplemental
briefs to present recent Texas Supreme Court decisions relevant to the appeal
were filed with the Fifth Court of Appeals by the Company and its co-plaintiffs
on December 18, 1998, and responded to by Appellants on January 6, 1999. On
January 12, 1999, oral argument was held. This matter is now fully submitted to
and before the Fifth Court of Appeals for decision.

      In the Jesus Yzaguirre Suit, certain of the royalty owners counterclaimed
against the Company, asserting that the largest lease contained therein had
terminated in December 1975, and that they were entitled to the Tennessee Gas
Contract price because of the execution of certain division orders in 1992 that
allegedly varied the market value royalty provision of their lease. On May 30,
1997, the Company and these royalty owners reached a settlement of the lease
termination claims, and on June 2, 1997, this issue was dismissed from the Jesus
Yzaguirre Suit. On June 17, 1997, the Company and the royalty owners moved for
summary judgment on the issue of the effect of division orders. The trial judge
granted the Company's motion and denied the competing motion on August 12, 1997.
On October 29, 1997, a final judgment was signed, and on November 19, 1997, the
royalty owners gave notice of their appeal to the Fifth Court of Appeals in
Dallas, Texas. The appellate record has been filed and the royalty owners' brief
was filed with the Fifth Court of Appeals on March 18, 1998. The Company filed
its brief in response on April 16, 1998. The parties have requested oral
argument on the Appellants' issues that it was an error for the trial court to
grant summary judgment for the Company on the unambiguous lease provisions
requiring the Company to pay market-value royalties and against them on their
contention that the implied duty to market required the Company to pay royalties
based upon the higher contract price; to grant summary judgment to the Company
that the 1992 division orders did not override the express royalty provisions of
their leases under Texas law; to grant summary judgment declaring that their
counterclaims and affirmative defenses of fraud, negligent misrepresentations,
conspiracy and estoppel, as well as allegations of oral promises and a course of
conduct by the Company, did not change the unambiguous terms of the written
leases; to exclude Appellants' expert witness testimony on "market value" as
being inadmissable; to deny Appellants' efforts to transfer venue from Dallas
County to Zapata County; and to refuse to abate this suit in favor of
Appellants' later-filed suit against the Company in Zapata County. No date for
oral argument of this cause has been given to the parties.

      Given the inherent uncertainties of appellate matters and notwithstanding
that the Company's position on 


                                       42
<PAGE>   44

the market value and other issues is based upon established decisional law in
Texas, the Company is unable to provide any assurance of a favorable outcome of
the appeals from the summary judgments and evidentiary rulings in the Los Santos
Suit and the Jesus Yzaguirre Suit, inasmuch as the Appellants in each appeal can
obtain a reversal and remand for plenary trial upon showing that summary
judgment was improper because there exists an issue of material fact.

      The aggregate amount at issue in the Los Santos and Jesus Yzaguirre Suits,
apart from certain tort counterclaims and affirmative defenses alleged by the
landowner royalty holders, is a function of the quantity of natural gas for
which Tennessee Gas paid at the contract price. As of January 1, 1997 (the date
of the termination of the Tennessee Gas Contract) the amount of natural gas
taken by Tennessee Gas attributable to the royalty interests involved in the
Royalty Basis Suits was approximately 3.8 Bcf for which royalties have been paid
by the Company at the average price of approximately $1.63 per Mcf, net of
severance tax, compared to the average Tennessee Gas Contract price of
approximately $7.60 per Mcf, net of severance tax. Consequently, if the Company
loses in its litigation with these royalty interest owners on these claims, the
Company faces a maximum liability in the Royalty Basis Suits of approximately
$22.7 million, plus interest thereon.

Other

      The Company is also a party to various other lawsuits and governmental
proceedings, all arising in the ordinary course of business. Although the
outcome of all of the above proceedings cannot be predicted with certainty,
management does not expect such matters to have a material adverse effect,
either singly or in the aggregate, on the financial position or results of
operations of the Company.

13. Oil and Gas Producing Operations

      The following data is presented pursuant to FASB Statement No. 69 with
respect to oil and gas acquisition, exploration, development and producing
activities, which is based on estimates of year-end oil and gas reserve
quantities and forecasts of future development costs and production schedules.
These estimates and forecasts are inherently imprecise and subject to
substantial revision as a result of changes in estimates of remaining volumes,
prices, costs, and production rates.

      Except where otherwise provided by contractual agreement, future cash
inflows are estimated using year-end prices. Oil and gas prices at December 31,
1998 are not necessarily reflective of the prices the Company expects to receive
in the future. Other than gas sold under contractual arrangements including
swaps, futures contracts and options, gas prices were $2.15, $2.50 and $3.54 at
December 31, 1998, 1997 and 1996, respectively, and oil prices were $8.57,
$15.15 and $22.45 at December 31, 1998, 1997 and 1996, respectively.

      VPP volumes represent oil and gas reserves purchased from third parties
which generally entitle the Company to a specified volume of oil and gas to be
delivered over a stated time period. The related volumes stated herein reflect
scheduled amounts of oil and gas to be delivered to the Company at agreed
delivery points and future cash inflows are estimated at year-end prices.
Although specific terms of the Company's VPPs vary, the Company is generally
entitled to receive delivery of its scheduled oil and gas volumes, free of
drilling and lease operating costs and, in certain cases, free of state
severance taxes.

Production Revenues and Costs

      Information with respect to production revenues and costs related to oil
and gas producing activities is as follows:

Reserve Information (Unaudited)

      The following information with respect to the Company's 1998 net proved
oil and gas reserves are estimates based on reports prepared by KCS and
independent petroleum engineers. The reports for the KCS Medallion Resources,
Inc.; KCS Mountain Resources, Inc.; KCS Resources, Inc.; and KCS Michigan
Resources, Inc. properties, which collectively represent 85.4% of total KCS
proved reserves at December 31, 1998, were audited by Netherland, Sewell &
Associates, Inc. pursuant to the principles set forth in the Standards
Pertaining to the Estimating and Auditing of Oil and Gas Reserve Information
promulgated by the Society of Petroleum Engineers. Proved developed reserves
represent only those reserves expected to be recovered through existing wells
using equipment currently in place. Proved undeveloped reserves represent proved
reserves expected to be recovered from new wells or from existing wells after
material recompletion expenditures. All of the Company's reserves are located
within the United States.

                               TERMS OF FACILITIES

      2.1 Tranche A Loans.

            (a) Upon the terms and conditions and relying on the representations
      and warranties contained in this Agreement and the other Loan Documents,
      each Tranche A Lender severally agrees to make Loans (each a "Tranche A
      Loan") during the Tranche A Commitment Period on a revolving basis to or
      for the benefit of the Borrowers, or any combination of them, in an
      aggregate principal amount not to exceed at any time outstanding


                                       23
<PAGE>   29

      the lesser of the Tranche A Facility Amount of such Lender or the
      Percentage Share of such Lender of the Borrowing Base then in effect (for
      each Lender, its "Tranche A Commitment"); provided, however, that (i)
      Tranche A Obligations shall not exceed at any time the lesser of the
      Tranche A Commitment Amount or the Borrowing Base then in effect, and (ii)
      the sum of the outstanding principal balance of all Tranche A Loans by any
      Tranche A Lender plus the Percentage Share of such Lender of the L/C
      Exposure shall not exceed at any time an amount equal to the Percentage
      Share of such Lender multiplied by the lesser of the Tranche A Commitment
      Amount or the Borrowing Base then in effect. Tranche A Loans shall be made
      from time to time on any Business Day designated by the Borrowers in a
      Borrowing Request.

            (b) Subject to the terms of this Agreement, during the Tranche A
      Commitment Period, the Borrowers may borrow, repay, and reborrow and
      convert Tranche A Loans of one type or with one Interest Period into
      Tranche A Loans of another type or with a different Interest Period.
      Except for prepayments made pursuant to Section 2.13, each borrowing,
      conversion, and prepayment of principal, in the case of Base Rate Loans,
      shall be in an amount at least equal to $100,000 and in multiples of
      $100,000 thereafter and, in the case of LIBO Rate Loans, shall be in an
      amount at least equal to $1,000,000 and in multiples of $100,000
      thereafter. Each borrowing, prepayment, or conversion of or into a Tranche
      A Loan of a different type or, in the case of a LIBO Rate Tranche A Loan,
      having a different Interest Period, shall be deemed a separate borrowing,
      conversion, and prepayment for purposes of the foregoing, one for each
      type of Tranche A Loan or Interest Period. Anything in this Agreement to
      the contrary notwithstanding, the aggregate principal amount of LIBO Rate
      Tranche A Loans having the same Interest Period shall be at least equal to
      $1,000,000; and if any LIBO Rate Loan would otherwise be in a lesser
      principal amount for any period, such Tranche A Loan shall be a Base Rate
      Loan during such period.

            (c) Not later than noon, Eastern Standard or Daylight Savings Time,
      as the case may be, on the date specified for each borrowing of a Tranche
      A Loan, each Tranche A Lender shall make available to the Agent an amount
      equal to the Percentage Share of such Lender of the borrowing to be made
      on such date, at an account designated by the Agent, for the account of
      the Borrowers. The amount so received by the Agent shall, subject to the
      terms and conditions hereof, be made available to the Borrowers in
      immediately available funds by no later than 1:00 p.m. Eastern Standard or
      Daylight Savings Time, as the case may be, in an account designated from
      time to time by the Borrowers. All Tranche A Loans by each Tranche A
      Lender shall be maintained at the Applicable Lending Office of such Lender
      and shall be evidenced by the Tranche A Note of such Lender.

            (d) The failure of any Tranche A Lender to make any Tranche A Loan
      required to be made by it hereunder shall not relieve any other Tranche A
      Lender of its obligation to make any Tranche A Loan required to be made by
      it, and no Tranche A Lender shall be responsible for the failure of any
      other Tranche A Lender to make any Tranche A Loan.

      2.2 Letter of Credit Facility.

<PAGE>   30

            (a) Upon the terms and conditions and relying on the representations
      and warranties contained in this Agreement, the Agent, as issuing bank for
      the Lenders, agrees, from the date of this Agreement until the date which
      is 30 days prior to the Tranche A Commitment Termination Date, to issue,
      on behalf of the Tranche A Lenders in their respective Percentage Shares,
      Letters of Credit for the account of the Borrowers, or any combination of
      them, and to renew and extend such Letters of Credit. Letters of Credit
      shall be issued, renewed, or extended from time to time on any Business
      Day designated by the Borrowers following the receipt in accordance with
      the terms hereof by the Agent of the written (or oral, confirmed promptly
      in writing) request by a Responsible Officer of each of the Borrowers
      therefor and a Letter of Credit Application. Letters of Credit shall be
      issued in such amounts as the Borrowers may request; provided, however,
      that (i) no Letter of Credit shall have an expiration date which is more
      than 365 days after the issuance thereof or subsequent to one Business Day
      prior to the Tranche A Commitment Termination Date, (ii) Tranche A
      Obligations shall not exceed at any time the lesser of the Tranche A
      Commitment Amount or the Borrowing Base, (iii) the L/C Exposure shall not
      exceed at any time $20,000,000, and (iv) no Letter of Credit shall be
      issued in an amount less than $50,000.

            (b) Prior to any Letter of Credit Payment in respect of any Letter
      of Credit, each Tranche A Lender shall be deemed to be a participant
      through the Agent with respect to the relevant Letter of Credit in the
      obligation of the Agent, as the issuer of such Letter of Credit, in an
      amount equal to the Percentage Share of such Lender of the maximum amount
      which is or at any time may become available to be drawn thereunder. Upon
      delivery by such Lender of funds requested pursuant to Section 2.2(c),
      such Lender shall be treated as having purchased a participating interest
      in an amount equal to such funds delivered by such Lender to the Agent in
      the obligation of the Borrowers to reimburse the Agent, as the issuer of
      such Letter of Credit, for any amounts payable, paid, or incurred by the
      Agent, as the issuer of such Letter of Credit, with respect to such Letter
      of Credit.

            (c) Each Tranche A Lender shall be unconditionally and irrevocably
      liable, without regard to the occurrence of any Default or Event of
      Default, to the extent of the Percentage Share of such Lender at the time
      of issuance of each Letter of Credit, to reimburse, on demand, the Agent,
      as the issuer of such Letter of Credit, for the amount of each Letter of
      Credit Payment under such Letter of Credit. Each Letter of Credit Payment
      shall be deemed to be a Base Rate Tranche A Loan by each Tranche A Lender
      to the extent of funds delivered by such Lender to the Agent with respect
      to such Letter of Credit Payment and shall to such extent be deemed a Base
      Rate Tranche A Loan under and shall be evidenced by the Tranche A Note of
      such Lender. In the event that a Default has occurred and is continuing
      under Sections 7.1(f) or (g), an amount equal to any Letter of Credit
      Payment made after the occurrence of such Default shall be payable by the
      Borrowers upon demand by the Agent. Notwithstanding anything contained
      herein or any other Loan Document (including any Letter of Credit
      Application), but subject to the provisions of Section 2.13, neither the
      Agent as the issuing bank nor any such Lender shall have any right to
      require any Borrower to prepay any amounts for which the Agent as the
      issuing bank or any Lender might become liable under any Letter of Credit.

<PAGE>   31

            (d) EACH TRANCHE A LENDER AGREES TO INDEMNIFY THE AGENT, AS THE
      ISSUER OF EACH LETTER OF CREDIT, AND THE OFFICERS, DIRECTORS, EMPLOYEES,
      AGENTS, ATTORNEYS-IN-FACT AND AFFILIATES OF THE AGENT (TO THE EXTENT NOT
      REIMBURSED BY THE BORROWERS AND WITHOUT LIMITING THE OBLIGATION OF THE
      BORROWERS TO DO SO), RATABLY ACCORDING TO THE PERCENTAGE SHARE OF SUCH
      LENDER AT THE TIME OF ISSUANCE OF SUCH LETTER OF CREDIT, FROM AND AGAINST
      ANY AND ALL LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES,
      ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND
      WHATSOEVER WHICH MAY AT ANY TIME (INCLUDING ANY TIME FOLLOWING THE PAYMENT
      AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT)
      BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE AGENT AS THE ISSUER OF
      SUCH LETTER OF CREDIT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES,
      AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES IN ANY WAY RELATING TO OR ARISING
      OUT OF THIS AGREEMENT OR SUCH LETTER OF CREDIT OR ANY ACTION TAKEN OR
      OMITTED BY THE AGENT AS THE ISSUER OF SUCH LETTER OF CREDIT OR ANY OF ITS
      OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES
      UNDER OR IN CONNECTION WITH ANY OF THE FOREGOING, INCLUDING ANY
      LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
      JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS IMPOSED, INCURRED OR
      ASSERTED AS A RESULT OF THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE
      AGENT AS THE ISSUER OF SUCH LETTER OF CREDIT OR ANY OF ITS OFFICERS,
      DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES; PROVIDED
      THAT NO TRANCHE A LENDER (OTHER THAN THE AGENT AS THE ISSUER OF A LETTER
      OF CREDIT) SHALL BE LIABLE FOR THE PAYMENT OF ANY PORTION OF SUCH
      LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS,
      SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING SOLELY FROM THE GROSS
      NEGLIGENCE OR WILLFUL MISCONDUCT OF THE AGENT AS THE ISSUER OF A LETTER OF
      CREDIT. THE AGREEMENTS IN THIS SECTION 2.2(d) SHALL SURVIVE THE PAYMENT
      AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT.

      2.3 Tranche B Loans.

            (a) Upon the terms and conditions and relying on the representations
      and warranties contained in this Agreement and the other Loan Documents,
      each Tranche B Lender severally agrees to make Loans (each a "Tranche B
      Loan") during the Tranche B Commitment Period on a revolving basis to or
      for the benefit of the Borrowers, or any combination of them, in an
      aggregate principal amount not to exceed at any time outstanding the
      lesser of the Tranche B Facility Amount of such Tranche B Lender or the
      Percentage Share of such Tranche B Lender of the Tranche B Borrowing Base
      then in effect (for each Tranche B Lender, its "Tranche B Commitment");
      provided, however, that Tranche B Obligations shall not exceed at any time
      the lesser of (y) the Tranche B Commitment Amount or (z) the difference
      between the Tranche B Borrowing Base then in effect minus the Borrowing
      Base then in effect. Tranche B Loans shall be made from time to time on
      any Business Day designated by the Borrowers in a Tranche B Borrowing
      Request but only to the extent such Tranche B Loan requested exceeds the
      Available Tranche A Commitment at such time.


                                       26
<PAGE>   32

            (b) Subject to the terms of this Agreement, during the Tranche B
      Commitment Period, the Borrowers may borrow, repay, and reborrow and
      convert Tranche B Loans of one type or with one Interest Period into
      Tranche B Loans of another type or with a different Interest Period.
      Except for prepayments made pursuant to Section 2.13, each borrowing,
      conversion, and prepayment of principal, in the case of Base Rate Loans,
      shall be in an amount at least equal to $100,000 and in multiples of
      $100,000 thereafter and, in the case of LIBO Rate Loans, shall be in an
      amount at least equal to $1,000,000 and in multiples of $100,000
      thereafter. Each borrowing, prepayment, or conversion of or into a Tranche
      B Loan of a different type or, in the case of a LIBO Rate Tranche B Loan,
      having a different Interest Period, shall be deemed a separate borrowing,
      conversion, and prepayment for purposes of the foregoing, one for each
      type of Tranche B Loan or Interest Period. Anything in this Agreement to
      the contrary notwithstanding, the aggregate principal amount of LIBO Rate
      Tranche B Loans having the same Interest Period shall be at least equal to
      $1,000,000; and if any LIBO Rate Loan would otherwise be in a lesser
      principal amount for any period, such Tranche B Loan shall be a Base Rate
      Loan during such period.

            (c) Not later than noon, Eastern Standard or Daylight Savings Time,
      as the case may be, on the date specified for each borrowing of a Tranche
      B Loan, each Tranche B Lender shall make available to the Agent an amount
      equal to the Percentage Share of such Tranche B Lender of the borrowing to
      be made on such date, at an account designated by the Agent, for the
      account of the Borrower. The amount so received by the Agent shall,
      subject to the terms and conditions hereof, be made available to the
      Borrowers in immediately available funds by no later than 1:00 p.m.
      Eastern Standard or Daylight Savings Time, as the case may be, in an
      account designated from time to time by the Borrowers. All Tranche B Loans
      by each Tranche B Lender shall be maintained at the Applicable Lending
      Office of such Lender and shall be evidenced by the Tranche B Note of such
      Lender.

            (d) The failure of any Tranche B Lender to make any Tranche B Loan
      required to be made by it hereunder shall not relieve any other Tranche B
      Lender of its obligation to make any Tranche B Loan required to be made by
      it, and no Tranche B Lender shall be responsible for the failure of any
      other Tranche B Lender to make any Tranche B Loan.

            (e) The Borrowers shall have the right at any time and from time to
      time, upon three (3) Business Days' prior and irrevocable written notice
      to the Agent, to terminate or reduce the Tranche B Commitments without
      premium or penalty, in whole or in part, any partial termination to be (i)
      in an amount not less than $1,000,000 as determined by the Borrowers and
      in integral multiples of $1,000,000, and (ii) allocated (A) either ratably
      among the Tranche B Lenders in proportion to their respective Tranche B
      Commitments; or (B) in the case of a termination of the Tranche B
      Commitment of a dissenting Tranche B Lender pursuant to Section 2.12(h),
      allocated solely to such Tranche B Lender; provided, that the Tranche B
      Commitment Amounts may not be reduced to an amount less than the Tranche B
      Loan Balance. The Agent shall give prompt notice to each Tranche B Lender
      of any termination or reduction of the Tranche B Commitments. Any
      termination of the Tranche B Commitments pursuant to this Section 2.3(e)
      is permanent and may not be revoked.


                                       27
<PAGE>   33

      2.4 Limitations on Interest Periods. Each Interest Period selected by the
Borrowers (a) which commences on the last Business Day of a calendar month (or
any day for which there is no numerically corresponding day in the appropriate
subsequent calendar month) shall end on the last Business Day of the appropriate
subsequent calendar month, (b) which would otherwise end on a day which is not a
Business Day shall end on the next succeeding Business Day (or, if such next
succeeding Business Day falls in the next succeeding calendar month, on the next
preceding Business Day), (c) which would otherwise end after Final Maturity
shall end on Final Maturity, and (d) shall have a duration of not less than one
month and, if any Interest Period would otherwise be a shorter period, the
relevant Loan shall be a Base Rate Loan during such period.

      2.5 Limitation on Types of Loans. Borrowings of both Tranche A Loans and
Tranche B Loans may be outstanding respectively as either Base Rate Loans or
LIBO Rate Loans as selected by Borrowers. Anything herein to the contrary
notwithstanding, no more than ten separate Tranche A Loans and five (5) separate
Tranche B Loans shall be outstanding at any one time, with, for purposes of this
Section, all Base Rate Tranche A Loans constituting one Loan, all Base Rate
Tranche B Loans constituting one Loan, all LIBO Rate Tranche A Loans for the
same Interest Period constituting one Loan, and all LIBO Rate Tranche B Loans
for the same Interest Period constituting one Loan. Anything herein to the
contrary notwithstanding, if, on or prior to the determination of any interest
rate for any LIBO Rate Loan for any Interest Period therefor:

            (a) the Agent determines (which determination shall be conclusive,
      absent manifest error) that quotations of interest rates for the deposits
      referred to in the definition of "LIBO Rate" in Section 1.2 are not being
      provided in the relevant amounts or for the relevant maturities for
      purposes of determining the rate of interest for such Loan as provided in
      this Agreement; or

            (b) the Agent or the Required Lenders determine (which determination
      shall be conclusive, absent manifest error) that the rates of interest
      referred to in the definition of "LIBO Rate" in Section 1.2 upon the basis
      of which the rate of interest for such Loan for such Interest Period is to
      be determined do not adequately cover the cost to the Lenders of making or
      maintaining such Loan for such Interest Period,

then the Agent shall give the Borrowers and the Lenders prompt notice thereof;
and so long as such condition remains in effect, the Lenders shall be under no
obligation to make LIBO Rate Loans or to convert Base Rate Loans into LIBO Rate
Loans, and the Borrowers shall, on the last day of the then current Interest
Period for each outstanding LIBO Rate Loan, either prepay such LIBO Rate Loan or
convert such Loan into a Base Rate Loan in accordance with Section 2.14. During
the 30 days next succeeding the giving of such notice by the Agent to the
Borrowers, the Borrowers, the Agent and each of the Lenders shall negotiate in
good faith in order to arrive at a mutually satisfactory interest rate for the
rates of interest referred to in the definition "LIBO Rate" or "Adjusted LIBO
Rate" for proposed LIBO Rate Loans. If within such 30-day period the Borrowers,
the Agent and the Lenders shall agree in writing upon a substitute interest rate
and the effective date thereof, such substituted interest rate shall be
applicable to all requests by the Borrowers for proposed LIBO Rate Loans. During
any period when the borrowing of LIBO Rate Loans is suspended or when an
alternative interest rate is in force pursuant to this subsection, the Agent, in


                                       28
<PAGE>   34

consultation with the Lenders, shall periodically, at least once a month,
determine whether circumstances are such that the interest rates referred to in
the definitions of "LIBO Rate" or "Adjusted LIBO Rate" may again be determined.
If such a determination is made, the Agent shall forthwith give written notice
to the Borrowers and each Lender, whereupon the Agent, the Borrowers and the
Lenders shall begin redetermining the "LIBO Rate" and the "Adjusted LIBO Rate"
in accordance with the terms of the definitions thereof.

      2.6 Use of Loan Proceeds and Letters of Credit.

            (a) Proceeds of all Loans shall be used solely by the Borrowers for
      general corporate purposes, acquisitions and working capital.

            (b) Letters of Credit shall be used solely by the Borrowers for
      general corporate purposes.

      2.7 Interest. Subject to the terms of this Agreement (including Section
2.20), interest on the Loans shall accrue and be payable at a rate per annum
equal to the lesser of (a) the Highest Lawful Rate or (b) the Adjusted Base Rate
for each Base Rate Loan or the Adjusted LIBO Rate for each LIBO Rate Loan.
Notwithstanding the foregoing, interest on past-due principal and, to the extent
permitted by applicable law, past-due interest, shall accrue at the Default Rate
and shall be payable upon demand by the Agent at any time as to all or any
portion of such interest. In the event that the Borrower fails to select the
duration of any Interest Period for any LIBO Rate Loan within the time period
and otherwise as provided herein, such Loan (if outstanding as a LIBO Rate Loan)
will be automatically converted into a Base Rate Loan on the last day of the
then current Interest Period for such Loan or (if outstanding as a Base Rate
Loan) will remain as, or (if not then outstanding) will be made as, a Base Rate
Loan. Interest provided for herein shall be calculated on unpaid sums actually
advanced and outstanding pursuant to the terms of this Agreement and only for
the period from the date or dates of such advances until repayment.

      2.8 Repayment of Loans and Interest. Accrued and unpaid interest on each
outstanding Base Rate Loan shall be due and payable quarterly commencing on the
31st day of December, 1998, and continuing on the last day of each third
calendar month thereafter while any Base Rate Loan remains outstanding, the
payment in each instance to be the amount of interest which has accrued and
remains unpaid in respect of the relevant Loan. Accrued and unpaid interest on
each outstanding LIBO Rate Loan shall be due and payable on the last day of the
Interest Period for such LIBO Rate Loan and, in the case of any Interest Period
in excess of three months, on the day of the third calendar month following the
commencement of such Interest Period corresponding to the day of the calendar
month on which such Interest Period commenced, the payment in each instance to
be the amount of interest which has accrued and remains unpaid in respect of the
relevant Loan. The outstanding principal balance of all Loans, together with all
accrued and unpaid interest thereon, shall be due and payable at Final Maturity.
At the time of making each payment hereunder or under the Notes, the Borrowers
shall specify to the Agent the Loans or other amounts payable by the Borrowers
hereunder to which such payment is to be applied. In the event the Borrowers
fail to so specify, or if an Event of Default has occurred and is continuing,
the Agent shall apply such payment in such manner as the Lenders shall determine
in their sole discretion.


                                       29
<PAGE>   35

      2.9 General Terms.

            (a) The outstanding principal balance of the Notes of each Lender
      reflected in the records of such Lender shall be deemed rebuttably
      presumptive evidence of the principal amount owing on such Notes. The
      liability for payment of principal and interest evidenced by each such
      Note shall be limited to principal amounts actually advanced and
      outstanding pursuant to this Agreement and interest on such amounts
      calculated in accordance with this Agreement.

            (b) Unless the Agent shall have been notified by a Lender or the
      Borrowers prior to the date on which any of them is scheduled to make
      payment to the Agent of (in the case of a Lender) the proceeds of a Loan
      to be made by such Lender hereunder or (in the case of the Borrowers) a
      payment to the Agent for the account of one or more of the Lenders
      hereunder (such payment, in either case, being herein called the "Required
      Payment"), which notice shall be effective upon receipt, that it does not
      intend to make the Required Payment to the Agent, the Agent may assume
      that the Required Payment has been made and, in reliance upon such
      assumption, may (but shall not be required to) make the amount thereof
      available to the intended recipient on such date. If such Lender or the
      Borrowers, as the case may be, have not in fact made the Required Payment
      to the Agent, the recipient of such payment shall, on demand, repay to the
      Agent for its account the amount so made available together with interest
      thereon in respect of each day during the period commencing on the date
      such amount was so made available by the Agent until the date the Agent
      recovers such amount at a rate per annum equal to, in the case of a Lender
      as recipient, the Federal Funds Rate or, in the case of the Borrowers as
      recipient, the Adjusted Base Rate.

      2.10 Time, Place, and Method of Payments. All payments required pursuant
to this Agreement or the Notes shall be made without set-off or counterclaim in
U.S. Dollars and in immediately available funds. All payments by the Borrowers
shall be deemed received on the next Business Day following receipt if such
receipt is after 3:00 p.m., Eastern Standard or Daylight Savings Time, as the
case may be, on any Business Day, and shall be made to the Agent at the
Principal Office. Except as provided to the contrary herein, if the due date of
any payment hereunder or under any Note would otherwise fall on a day which is
not a Business Day, such date shall be extended to the next succeeding Business
Day, and interest shall be payable for any principal so extended for the period
of such extension.

      2.11 Pro Rata Treatment; Adjustments.

            (a) Except to the extent otherwise expressly provided herein, (i)
      each borrowing of Tranche A Loans pursuant to this Agreement shall be made
      from the Tranche A Lenders pro rata in accordance with their respective
      Percentage Shares, (ii) each payment by the Borrowers of fees payable by
      the Borrowers in respect of Tranche A Loans shall be made for the account
      of the Tranche A Lenders pro rata in accordance with their respective
      Percentage Shares, (iii) each payment of principal of Tranche A Loans
      shall be made for the account of the Tranche A Lenders pro rata in
      accordance with their respective shares of the Tranche A Loan Balance,
      (iv) each payment of interest on Tranche A Loans shall be made


                                       30
<PAGE>   36

      for the account of the Tranche A Lenders pro rata in accordance with their
      respective Percentage Shares of the aggregate amount of such interest due
      and payable to the Tranche A Lenders, (v) each borrowing of Tranche B
      Loans shall be made from the Tranche B Lenders pro rata in accordance with
      their respective Percentage Shares, (vi) each payment by the Borrowers of
      fees payable by the Borrowers in respect of Tranche B Loans shall be made
      for the account of the Tranche B Lenders pro rata in accordance with their
      respective Percentage Shares, (vii) each payment of principal of Tranche B
      Loans shall be made for the account of the Tranche B Lenders pro rata in
      accordance with their respective shares of the Tranche B Loan Balance, and
      (viii) each payment of interest on Tranche B Loans shall be made for the
      account of the Tranche B Lenders pro rata in accordance with their
      respective Percentage Shares of the aggregate amount of such interest due
      and payable to the Tranche B Lenders.

            (b) The Agent shall distribute all payments with respect to the
      Obligations to the Lenders promptly upon receipt in like funds as
      received. In the event that any payments made hereunder by the Borrowers
      at any particular time are insufficient to satisfy in full the Obligations
      due and payable at such time, such payments shall be applied (i) first, to
      fees and expenses due pursuant to the terms of this Agreement or any other
      Loan Document, (ii) second, to accrued interest, (iii) third, to the Loan
      Balance of the Loans, and (iv) last, to any other Obligations.

            (c) If any Tranche A Lender (for purposes of this Section, a
      "Benefitted Tranche A Lender") shall at any time receive any payment of
      all or part of its portion of the Obligations, or receive any Collateral
      in respect thereof (whether voluntarily or involuntarily, by set-off,
      pursuant to events or proceedings of the nature referred to in Sections
      7.1(f) or 7.1(g), or otherwise) in an amount greater than such Lender was
      entitled to receive pursuant to the terms hereof, such Benefitted Tranche
      A Lender shall purchase for cash from the other Tranche A Lenders such
      portion of the Obligations of such other Lenders, or shall provide such
      other Tranche A Lenders with the benefits of any such Collateral or the
      proceeds thereof, as shall be necessary to cause such Benefitted Tranche A
      Lender to share the excess payment or benefits of such Collateral or
      proceeds with each of the Tranche A Lenders according to the terms hereof.
      If all or any portion of such excess payment or benefits is thereafter
      recovered from such Benefitted Tranche A Lender, such purchase shall be
      rescinded and the purchase price and benefits returned by such Lender, to
      the extent of such recovery, but without interest. The Borrower agrees
      that each such Lender so purchasing a portion of the Obligations of
      another Lender may exercise all rights of payment (including rights of
      set-off) with respect to such portion as fully as if such Lender were the
      direct holder of such portion. If any Tranche A Lender ever receives, by
      voluntary payment, exercise of rights of set-off or banker's lien,
      counterclaim, cross-action or otherwise, any funds of the Borrower to be
      applied to the Obligations, or receives any proceeds by realization on or
      with respect to any Collateral, all such funds and proceeds shall be
      forwarded immediately to the Agent for distribution in accordance with the
      terms of this Agreement.

            (d) If any Tranche B Lender (for purposes of this Section, a
      "Benefitted Tranche B Lender") shall at any time receive any payment of
      all or part of its portion of the


                                       31
<PAGE>   37

      Obligations, or receive any Collateral in respect thereof (whether
      voluntarily or involuntarily, by set-off, pursuant to events or
      proceedings of the nature referred to in Sections 7.1(f) or 7.1(g), or
      otherwise) in an amount greater than such Lender was entitled to receive
      pursuant to the terms hereof, such Benefitted Tranche B Lender shall
      purchase for cash from the other Tranche B Lenders such portion of the
      Obligations of such other Lenders, or shall provide such other Tranche B
      Lenders with the benefits of any such Collateral or the proceeds thereof,
      as shall be necessary to cause such Benefitted Tranche B Lender to share
      the excess payment or benefits of such Collateral or proceeds with each of
      the Tranche B Lenders according to the terms hereof. If all or any portion
      of such excess payment or benefits is thereafter recovered from such
      Benefitted Tranche B Lender, such purchase shall be rescinded and the
      purchase price and benefits returned by such Lender, to the extent of such
      recovery, but without interest. The Borrower agrees that each such Lender
      so purchasing a portion of the Obligations of another Lender may exercise
      all rights of payment (including rights of set-off) with respect to such
      portion as fully as if such Lender were the direct holder of such portion.
      If any Tranche B Lender ever receives, by voluntary payment, exercise of
      rights of set-off or banker's lien, counterclaim, cross-action or
      otherwise, any funds of the Borrower to be applied to the Obligations, or
      receives any proceeds by realization on or with respect to any Collateral,
      all such funds and proceeds shall be forwarded immediately to the Agent
      for distribution in accordance with the terms of this Agreement.

            (e) Notwithstanding any of the provisions of this Section 2.11,
      after the occurrence and during the continuance of an Event of Default,
      the Lenders may apply payments in respect of the Obligations in such
      manner as the Lenders shall determine in their sole discretion.

      2.12 Borrowing Base and Tranche B Borrowing Base Determinations.

            (a) The Borrowing Base as of the Closing Date is agreed by the
      Borrowers and the Tranche A Lenders to be $65,000,000.

            (b) The Borrowing Base shall be redetermined by the Agent, with the
      consent of the Tranche A Lenders, semi-annually on the basis of
      information supplied by the Borrowers in compliance with the provisions of
      this Agreement, including Reserve Reports, and all other information
      available to the Agent and the Lenders. In addition, the Agent, with the
      consent of the Tranche A Lenders, shall, in the normal course of business
      following a request of the Borrowers, redetermine the Borrowing Base;
      provided, however, the Agent and the Tranche A Lenders shall not be
      obligated to respond to more than two (2) such requests during any
      calendar year in addition to each scheduled semi-annual redetermination
      provided for above. Notwithstanding the foregoing, the Agent, with the
      consent of the Tranche A Lenders, may at its discretion redetermine the
      Borrowing Base at any time and from time to time.

            (c) Each determination of the Borrowing Base shall be made within
      forty-five (45) days of the Agent's receiving all of the information
      required under this Agreement in connection therewith. Upon each
      determination of the Borrowing Base, the Agent shall


                                       32
<PAGE>   38

      promptly, and in all events within such 45 days, notify the Borrowers
      orally (confirming such notice promptly in writing) of such determination
      and the Borrowing Base so communicated to the Borrowers shall become
      effective upon such oral notification and shall remain in effect until the
      next subsequent determination of the Borrowing Base.

            (d) In connection with any redetermination of the Borrowing Base,
      the Agent and each Tranche A Lender shall evaluate the Mortgaged
      Properties in accordance with their then existing customary lending
      procedures for evaluating oil and gas reserves and related assets for
      loans of this type and borrowers similarly situated. The Borrowing Base
      shall represent the determination by the Agent based upon such evaluation
      by the Agent, with the consent of the Tranche A Lenders, of the value for
      loan purposes of the Mortgaged Properties, subject, in the case of any
      increase in the Borrowing Base, to the credit approval processes of the
      Tranche A Lenders then in effect for loans of this type and borrowers
      similarly situated. Except as hereinafter provided, in the event that a
      group of Tranche A Lenders constituting at least the Tranche A Required
      Lenders are in agreement as to the amount of any Borrowing Base
      redetermination but such amount is not approved unanimously by all of the
      Tranche A Lenders, then the Borrowing Base shall be the amount as
      determined by such Tranche A Required Lenders for a period of 60 days from
      the date of notification of such Borrowing Base to the Borrowers pursuant
      to Section 2.12(c). Notwithstanding the foregoing provisions of this
      Section 2.12(d), if at any time the Borrowing Base redetermination by the
      Agent results in an increase in the Borrowing Base and such Borrowing Base
      is not approved unanimously by all the Tranche A Lenders, then, in such
      event, the Borrowing Base shall, during the sixty (60) day period from the
      date of notification of the Borrowing Base to the Borrowers pursuant to
      Section 2.12(c), be the amount agreed to by the Agent and all of the
      Tranche A Lenders, but in any event not less than the amount which existed
      immediately prior to such redetermination by the Agent. During such 60 day
      period or at any time thereafter, the Borrowers may, at their election,
      terminate the Commitments of such dissenting Tranche A Lenders pursuant to
      the procedures set forth in Section 2.25. At the end of such 60 day
      period, the Borrowing Base shall be an amount agreed to by the Agent and
      all of the Tranche A Lenders. Furthermore, subject to the customary
      lending procedures and credit approval processes referred to in the
      preceding sentence, each Borrower acknowledges that the Agent and the
      Lenders have no obligation to increase the Borrowing Base and may reduce
      the Borrowing Base, in either case, at any time or as a result of any
      circumstance, and further acknowledges that the determination of the
      Borrowing Base contains an equity cushion (market value in excess of loan
      value), which is acknowledged by each Borrower to be essential for the
      adequate protection of the Tranche A Lenders.

            (e) The Tranche B Borrowing Base (the "Tranche B Borrowing Base") is
      agreed by the Borrowers and the Tranche B Lenders to be (i) $75,000,000
      from the Closing Date through the later of (y) March 31, 1999 and (z) the
      date of the next determination of the Tranche B Borrowing Base in
      accordance with Section 2.12(f), (g) and (h), and (ii) thereafter, such
      amount as shall be determined by the Tranche B Lenders in the manner
      provided in Section 2.12(f), (g) and (h) of this Agreement.

            (f) The Tranche B Borrowing Base shall be redetermined by the Agent,
      with the consent of the Tranche B Lenders, semi-annually commencing March
      31, 1999 on the basis of information supplied by the Borrowers in
      compliance with the provisions of this


                                       33
<PAGE>   39

      Agreement, including Reserve Reports, and all other information available
      to the Agent and the Lenders. In addition, the Agent, with the consent of
      the Tranche B Lenders, with the assistance of the Agent, shall, in the
      normal course of business following a request of the Borrowers,
      redetermine the Borrowing Base; provided, however, the Agent and the
      Tranche B Lenders shall not be obligated to respond to more than two (2)
      such requests during any calendar year in addition to each scheduled
      semi-annual redetermination provided for above. Notwithstanding the
      foregoing, the Agent, with the consent of the Tranche B Lenders, may
      (except as provided in Section 2.12(e)(i)) at its discretion redetermine
      the Tranche B Borrowing Base at any time and from time to time.

            (g) Each determination of the Tranche B Borrowing Base shall be made
      within forty-five (45) days of the Agent's receiving all of the
      information required under this Agreement in connection therewith. Upon
      each determination of the Tranche B Borrowing Base, the Agent shall
      promptly, and in all events within such 45 days, notify the Borrowers
      orally (confirming such notice promptly in writing) of such determination
      and the Tranche B Borrowing Base so communicated to the Borrowers shall
      become effective upon such oral notification and shall remain in effect
      until the next subsequent determination of the Tranche B Borrowing Base.

            (h) In connection with any redetermination of the Tranche B
      Borrowing Base, the Agent and each Tranche B Lender shall evaluate the
      Mortgaged Properties in accordance with their then existing customary
      lending procedures for evaluating oil and gas reserves and related assets
      for loans of this type and borrowers similarly situated. The Tranche B
      Borrowing Base shall represent the determination by the Agent based upon
      such evaluation by the Agent, with the consent of the Tranche B Lenders,
      of the value for loan purposes of the Mortgaged Properties, subject, in
      the case of any increase in the Tranche B Borrowing Base, to the credit
      approval processes of the Tranche B Lenders then in effect for loans of
      this type and borrowers similarly situated. In the event that a group of
      Tranche B Lenders constituting at least the Tranche B Required Lenders are
      in agreement as to the amount of any Tranche B Borrowing Base
      redetermination but such amount is not approved unanimously by all of the
      Tranche B Lenders, then the Tranche B Borrowing Base shall be the amount
      as determined by such Tranche B Required Lenders for a period of 60 days
      from the date of notification of such Tranche B Borrowing Base to the
      Borrowers pursuant to Section 2.12(g). During such 60 day period or at any
      time thereafter, the Borrowers may, at their election, (x) terminate the
      Tranche B Commitment of such dissenting Tranche B Lender(s) in accordance
      with Section 2.3(e), or (y) substitute a new Tranche B Lender or Lenders
      for such dissenting Lender(s) pursuant to the procedures set forth in
      Section 2.25. At the end of such 60 day period, the Tranche B Borrowing
      Base shall be an amount agreed to by the Agent and all of the Tranche B
      Lenders. Furthermore, subject to the customary lending procedures and
      credit approval processes referred to in the preceding sentence, each
      Borrower acknowledges that the Agent and the Tranche B Lenders have no
      obligation to increase the Tranche B Borrowing Base and may, subject to
      Section 2.12(e)(i), reduce the Tranche B Borrowing Base, in either case,
      at any time or as a result of any circumstance, and further acknowledges
      that the determination of the Tranche B Borrowing Base contains an


                                       34
<PAGE>   40

      equity cushion (market value in excess of loan value), which is
      acknowledged by each Borrower to be essential for the adequate protection
      of the Tranche B Lenders.

      2.13 Mandatory Prepayments.

            (a) If at any time the Tranche A Obligations exceed the lesser of
      the Tranche A Commitment Amount or the Borrowing Base then in effect, the
      Borrowers shall, within 30 days of notice from the Agent of such
      occurrence, (i) prepay, or make arrangements acceptable to the Tranche A
      Required Lenders for the prepayment of, the amount of such excess for
      application on the Loan Balance of the Tranche A Loans, (ii) provide
      additional collateral, of character and value satisfactory to the Tranche
      A Required Lenders in their sole discretion, to secure the Obligations by
      the execution and delivery to the Agent of security instruments in form
      and substance satisfactory to the Agent, or (iii) effect any combination
      of the alternatives described in clauses (i) and (ii) of this Section
      2.13(a) and acceptable to the Tranche A Required Lenders in their
      discretion. In the event that a mandatory prepayment is required under
      this Section 2.13(a) and the Tranche A Loan Balance is less than the
      amount required to be prepaid, the Borrowers shall repay the entire
      Tranche A Loan Balance together with accrued interest, and, in accordance
      with the provisions of the relevant Letter of Credit Applications executed
      by the Borrowers or otherwise to the satisfaction of the Agent, deposit
      with the Agent, as additional collateral securing the Obligations, an
      amount of cash, in immediately available funds, equal to the L/C Exposure
      minus the lesser of the Tranche A Commitment Amount or the Borrowing Base.
      The cash deposited with the Agent in satisfaction of the requirement
      provided in this Section 2.13 may be invested at the express direction of
      the Borrowers as to investment vehicle and maturity (which shall be no
      later than the latest expiry date of any then outstanding Letter of
      Credit), for the account of the Borrowers in cash or cash equivalent
      investments offered by or through the Agent.

            (b) For so long as any Tranche B Commitment is outstanding, in the
      event after the Closing Date the Guarantor or any Borrower (i) issues or
      incurs Subordinated Indebtedness or Public Debt to any Person other than
      an Affiliate or (ii) issues, transfers, sells, assigns, or conveys to any
      Person other than an Affiliate (an "Equity Sale") (y) all or any portion
      of the capital stock of the Guarantor or any other Borrower, or (z) any
      equity interest in itself or the Guarantor or any other Borrower, then, in
      any such event an amount equal to fifty percent (50%) of the Net Cash
      Proceeds from the issuance or incurrence of such Subordinated Indebtedness
      up to the then outstanding principal amount of the Tranche B Loans, if
      any, and fifty percent (50%) of the Net Cash Proceeds from the issuance,
      sale, assignment or conveyance of such Equity Sale up to the then
      outstanding principal amount of the Tranche B Loans, if any, shall be
      applied for reduction of the Tranche B Loans in the manner determined by
      the Lenders, and the Tranche B Commitments then in effect (if any) shall
      be irrevocably reduced pro rata to the extent of fifty percent (50%) of
      the Net Cash Proceeds from the issuance or incurrence of such Subordinated
      indebtedness or Public Debt and fifty percent (50%) of the Net Cash
      Proceeds from the issuance, sale, assignment or conveyance of such Equity
      Sale.


                                       35
<PAGE>   41

            (c) If at any time the Tranche B Obligations exceed the lesser of
      (i) the Tranche B Commitment Amount or (ii) the difference between the
      Tranche B Borrowing Base then in effect minus the Borrowing Base then in
      effect, the Borrowers shall, within 30 days of notice from the Agent of
      such occurrence, (i) prepay, or make arrangements acceptable to the
      Tranche B Required Lenders for the prepayment of, the amount of such
      excess for application on the Tranche B Loan Balance, (ii) provide
      additional collateral, of character and value satisfactory to the Tranche
      B Required Lenders in their sole discretion, to secure the Obligations by
      the execution and delivery to the Agent of security instruments in form
      and substance satisfactory to the Agent, or (iii) effect any combination
      of the alternatives described in clauses (i) and (ii) of this Section
      2.13(c) and acceptable to the Tranche B Required Lenders in their
      discretion. If at any time, Tranche B Obligations are outstanding when
      Available Tranche A Commitment exists, the Borrowers shall, (i) in the
      case of such Tranche B Obligations which are Base Rate Tranche B Loans, to
      the extent of the Available Tranche A Commitment, prepay such Loans within
      three Business Days of the occurrence of such condition, or (ii) in the
      case of such Tranche B Obligations which are LIBO Rate Tranche B Loans, to
      the extent of the Available Tranche A Commitment, on the last day of the
      Interest Period to which such Loans are subject, prepay such Loans on the
      last day of the Interest Period to which such Loans are subject. In the
      event that a mandatory prepayment is required under this Section 2.13(c)
      and the Tranche B Loan Balance is less than the amount required to be
      prepaid, the Borrowers shall repay the entire Loan Balance of the Tranche
      B Loans.

      2.14 Voluntary Prepayments and Conversions of Loans. Subject to applicable
provisions of this Agreement, the Borrowers shall have the right at any time or
from time to time to prepay Loans and to convert Loans of one type or with one
Interest Period into Loans of another type or with a different Interest Period;
provided, however, that (a) the Borrowers shall give the Agent notice of each
such conversion of all or any portion of a LIBO Rate Loan no less than three
Business Days prior to conversion, (b) any LIBO Rate Loan may be prepaid or
converted only on the last day of an Interest Period for such Loan, unless the
Borrowers pay, within the time period set forth therefor in Section 2.22(e), the
amount, if any, required to be paid under Section 2.22(e), (c) each prepayment,
in the case of Base Rate Loans, shall be in an amount not less than $100,000 or
incremental amounts of $100,000 in excess thereof or the Loan Balance of such
Loans and, in the case of LIBO Rate Loans, shall be in an amount not less than
$1,000,000 or incremental amounts of $100,000 in excess thereof or the Loan
Balance of such Loans, (d) the Borrower shall pay all accrued and unpaid
interest on the amounts prepaid or converted, and (e) no such prepayment or
conversion shall serve to postpone the repayment when due of any Obligation.

      2.15 Commitment Fees and Usage Fee.

            (a) To compensate the Tranche A Lenders for maintaining funds
      available under the Tranche A Commitment, the Borrowers shall pay to the
      Agent for the account of such Lenders a fee equal to (i) at all times the
      Tranche B Commitments are outstanding and existing, one-half of one
      percent (0.50%) per annum times the average daily amount of the Available
      Tranche A Commitment during the immediately preceding fiscal quarter just
      ended (or shorter period thereof in the case of the fee for the period
      from the date of this


                                       36
<PAGE>   42

      Agreement and ending December 31, 1998 or the period ending on the Tranche
      A Commitment Termination Date) or (ii) in the event the Tranche B
      Commitments are irrevocably terminated, (y) in the event the average daily
      amount of the Available Tranche A Commitment during the immediately
      preceding fiscal quarter just ended (or shorter period thereof in the case
      of the fee for the period from the date of this Agreement and ending
      December 31, 1998 or the period ending on the Tranche A Commitment
      Termination Date) is equal to or more than sixty-six and two-thirds
      percent (66 2/3%) of the average daily amount of the Tranche A Commitments
      during such immediately preceding fiscal quarter (or any such shorter
      period), thirty-seven and one-half one hundredths of one percent (0.375%)
      per annum times the average daily amount of the Available Tranche A
      Commitment for such quarter or shorter period, or (z) in the event the
      average daily amount of the Available Tranche A Commitment during the
      immediately preceding fiscal quarter just ended (or shorter period thereof
      in the case of the fee for the period from the date of this Agreement and
      ending December 31, 1998 or the period ending on the Tranche A Commitment
      Termination Date) is less than sixty-six and two thirds percent (66 2/3%)
      of the average daily amount of the Tranche A Commitments during such
      immediately preceding fiscal quarter (or any such shorter period), one
      half of one percent (0.50%) per annum times the average daily amount of
      the Available Tranche A Commitment for such quarter or shorter period, in
      each case calculated on the basis of a year of 365 or 366 days, as the
      case may be, and actual days elapsed (including the first day but
      excluding the last day); such accrued commitment fees shall be payable in
      arrears on the 31st day of December, 1998, the last day of each third
      calendar month thereafter during the Tranche A Commitment Period, and on
      the Tranche A Commitment Termination Date;

            (b) To compensate the Tranche B Lenders for maintaining funds
      available under the Tranche B Commitment the Borrowers shall pay to the
      Agent for the account of such Tranche B Lenders, a fee equal to one-half
      of one percent (0.50%) per annum, times the average daily amount of the
      Available Tranche B Commitment during the immediately preceding fiscal
      quarter just ended (or shorter period thereof in the case of the fee for
      the period from the date of this Agreement and ending December 31, 1998 or
      the period ending on the Tranche B Commitment Termination Date),
      calculated on the basis of a year of 365 or 366 days, as the case may be,
      and actual days elapsed (including the first day but excluding the last
      day); such accrued commitment fees shall be payable in arrears on the 31st
      day of December, 1998, the last day of each third calendar month
      thereafter during the Tranche B Commitment Period, and on the Tranche B
      Commitment Termination Date; and

            (c) To compensate the Tranche B Lenders for advancing Tranche B
      Loans, subject to the provisions of Section 2.20, on the date of any
      borrowing of a Tranche B Loan where, after giving effect to such Loan, the
      aggregate principal amount of Tranche B Loans then outstanding exceeds the
      maximum aggregate principal amount of Tranche B Loans theretofore
      outstanding at any one time (the amount of such excess on any such
      borrowing date, herein called an "Excess Amount"), the Borrowers shall pay
      to the Agent, for the account of the Tranche B Lenders, a fee ("Usage
      Fee") equal to one-and-one-fourth percent (1.25%) times such Excess Amount
      on such date of borrowing.

      2.16 Letter of Credit Fee. The Borrowers shall pay to the Agent for the
account of the Tranche A Lenders a letter of credit fee in the amount of the
Applicable Margin for LIBO Rate Loans in effect at such time per annum,
calculated on the basis of a year of 360 days and actual days elapsed (including
the first day but excluding the last day), on the average daily amount of the
L/C Exposure. Accrued letter of credit fees shall be payable quarterly in
arrears on the 31st day of December, 1998, the last day of each third calendar
month thereafter during the Tranche A Commitment Period, and at Final Maturity
of the Tranche A Loans. The Borrower shall pay to the Agent for its own account
as the issuer of each Letter of Credit, on the date of issuance or renewal of
each Letter of Credit, an issuing fee equal to one-eighth of one percent (.125%)
per annum, calculated on the basis of a year of 365 or 366 days, as the case may
be, and actual days elapsed (including the first day but excluding the last
day), on the face amount of such Letter of Credit during the period for which
such Letter of Credit is issued or renewed. The Borrowers also agree to pay on
demand to the Agent for its own account as the issuer of the Letters of Credit
its customary letter of credit transactional fees and expenses, including
amendment fees, payable with respect to each Letter of Credit.

      2.17 Other Fees. The Borrowers shall pay to the Agent on the Closing Date
(a) for the account of the Tranche A Lenders an amendment fee (the "Tranche A
Amendment Fee") equal to $81,250 representing one-eighth of one percent (0.125%)
of the aggregate of the Tranche A Commitments and (b) for the account of the
Tranche B Lenders, a commitment fee (the "Tranche B Commitment Fee") equal to
$125,000 representing one and one-fourth percent (1.25%) of the aggregate of the
Tranche B Commitments.

      2.18 Loans to Satisfy Obligations of Borrowers. The Lenders may, with the
consent of the Agent, but shall not be obligated to, make Loans for the benefit
of the Borrowers and apply proceeds thereof to the satisfaction of any
condition, warranty, representation, or covenant of the Borrowers or the
Guarantor contained in this Agreement or any other Loan Document. Such Loans
shall be evidenced by the Notes, shall bear interest at the Default Rate, and
shall be payable upon demand.

      2.19 Right of Offset. The Borrowers hereby grant to the Agent and each
Lender (for the benefit of all Lenders) the right, exercisable at such time as
any Event of Default shall occur, of offset or banker's lien against all funds
of the Borrowers now or hereafter or from time to time on deposit with the Agent
or such Lender, regardless of whether the exercise of any such remedy would
result in any penalty or loss of interest or profit with respect to any
withdrawal of funds deposited in a time deposit account prior to the maturity
thereof.

      2.20 General Provisions Relating to Interest.

            (a) It is the intention of the parties hereto to comply strictly
      with all applicable usury laws. In this connection, there shall never be
      collected, charged, or received on the sums advanced hereunder interest in
      excess of that which would accrue at the Highest Lawful Rate.


                                       38
<PAGE>   44

            (b) Notwithstanding anything herein or in the Notes to the contrary,
      during any Limitation Period, the interest rate to be charged on amounts
      evidenced by the Notes shall be the Highest Lawful Rate, and the
      obligation, if any, of each Borrower for the payment of fees or other
      charges deemed to be interest under applicable law shall be suspended.
      During any period or periods of time following a Limitation Period, to the
      extent permitted by applicable law, the interest rate to be charged
      hereunder shall remain at the Highest Lawful Rate until such time as there
      has been paid to the Agent and each Lender (i) the amount of interest in
      excess of that accruing at the Highest Lawful Rate that such Lender would
      have received during the Limitation Period had the interest rate remained
      at the otherwise applicable rate, and (ii) all interest and fees otherwise
      payable to the Agent and such Lender but for the effect of such Limitation
      Period.

            (c) If, under any circumstances, the aggregate amounts paid on the
      Notes or under this Agreement or any other Loan Document include amounts
      which by applicable law are deemed interest and which would exceed the
      amount permitted if the Highest Lawful Rate were in effect, each Borrower
      stipulates that such payment and collection will have been and will be
      deemed to have been, to the extent permitted by applicable law, the result
      of mathematical error on the part of such Borrower, the Agent, and the
      Lenders; and the party receiving such excess shall promptly refund the
      amount of such excess (to the extent only of such interest payments in
      excess of that which would have accrued and been payable on the basis of
      the Highest Lawful Rate) upon discovery of such error by such party or
      notice thereof from such Borrower. In the event that the maturity of any
      Obligation is accelerated, by reason of an election by the Lenders or
      otherwise, or in the event of any required or permitted prepayment, then
      the consideration constituting interest under applicable law may never
      exceed the Highest Lawful Rate, and excess amounts paid which by
      applicable law are deemed interest, if any, shall be credited by the Agent
      and the Lenders on the principal amount of the Obligations, or if the
      principal amount of the Obligations shall have been paid in full, refunded
      to such Borrower.

            (d) All sums paid, or agreed to be paid, to the Agent and the
      Lenders for the use, forbearance and detention of the proceeds of any
      advance hereunder shall, to the extent permitted by applicable law, be
      amortized, prorated, allocated, and spread throughout the full term hereof
      until paid in full so that the actual rate of interest is uniform but does
      not exceed the Highest Lawful Rate throughout the full term hereof.

      2.21 Obligations Absolute. Subject to the further provisions of this
Section, the Obligations of the Borrowers under this Article shall be absolute
and unconditional under any and all circumstances and irrespective of any
set-off, counterclaim, or defense to payment or performance which the Borrowers
may have or have had against the Agent, any Lender, or any beneficiary of any
Letter of Credit. Each Borrower agrees that none of the Agent or the Lenders
shall be responsible for, nor shall the Obligations be affected by, among other
things, (a) the validity or genuineness of documents or any endorsements thereon
presented in connection with any Letter of Credit, even if such documents shall
in fact prove to be in any and all respects invalid, fraudulent or forged, AND
EVEN IF DUE TO THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT OR ANY
LENDER, so long as the Agent, as the issuer of such Letter of Credit, has no
actual knowledge of any


                                       39
<PAGE>   45

such invalidity, lack of genuineness, fraud, or forgery prior to the presentment
for payment of a corresponding Letter of Credit or any draft thereunder, or (b)
any dispute between or among the Borrowers and any beneficiary of any Letter of
Credit or any other party to which any Letter of Credit may be transferred, or
any claims whatsoever of the Borrowers against any beneficiary of any Letter of
Credit or any such transferee, EVEN IF DUE TO THE NEGLIGENCE, WHETHER SOLE OR
CONCURRENT, OF THE AGENT OR ANY LENDER; provided, in all respects, that the
Agent, as the issuer of Letters of Credit, shall be liable to the Borrowers to
the extent, but only to the extent, of any damages (other than punitive damages)
suffered by the Borrowers as a result of the willful misconduct or gross
negligence of the Agent as the issuer of Letters of Credit in determining
whether documents presented under a Letter of Credit complied with the terms of
such Letter of Credit that resulted in either a wrongful payment under such
Letter of Credit or a wrongful dishonor of a claim or draft properly presented
under such Letter of Credit. In the absence of gross negligence or willful
misconduct by the Agent as the issuer of Letters of Credit, the Agent shall not
be liable for any error, omission, interruption or delay, EVEN IF DUE TO THE
NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT, in transmission, dispatch
or delivery of any message or advice, however transmitted, in connection with
any Letter of Credit. The Agent, the Lenders, and the Borrowers agree that any
action taken or omitted by the Agent, as issuer of any Letter of Credit, under
or in connection with any Letter of Credit or the related drafts or documents,
EVEN IF DUE TO THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT OR ANY
LENDER, if done in the absence of gross negligence or willful misconduct, shall
be binding as among the Agent, as issuer of such Letter of Credit or otherwise,
the Lenders, and the Borrowers and shall not put the Agent, as issuer of such
Letter of Credit or otherwise, or any Lender under any liability to the
Borrowers; provided, however, that no such action taken or omitted to be taken
by the Agent shall be binding upon the Borrowers as against any Person other
than the Agent and the Lenders. Notwithstanding any provision to the contrary in
this Section 2.21 or elsewhere in this Agreement, the Agent, as the issuer of
the Letters of Credit, agrees to exercise ordinary care in examining each
document required to be presented pursuant to each Letter of Credit to ascertain
that each such document appears on its face to comply with the terms thereof.

      2.22 Yield Protection.

            (a) Without limiting the effect of the other provisions of this
      Section (but without duplication), the Borrowers shall pay to the Agent
      and each Lender from time to time, within five (5) Business Days of
      receipt of the certificate provided for in Section 2.22(e), such amounts
      as the Agent or such Lender may reasonably determine are necessary to
      compensate it for any Additional Costs incurred by the Agent or such
      Lender.

            (b) Without limiting the effect of the other provisions of this
      Section (but without duplication), the Borrowers shall pay to each Lender
      from time to time, within five Business Days of receipt of the certificate
      provided for in Section 2.22(e), such amounts as such Lender may determine
      are necessary to compensate such Lender for any actual costs incurred by
      such Lender attributable to the maintenance by such Lender (or any
      Applicable Lending Office), pursuant to any Regulatory Change, of capital
      (other than the Reserve Requirement utilized in the determination of any
      Adjusted LIBO Rate or the Adjusted CD Rate) in respect of its Commitments,
      such compensation to include an amount equal to any reduction of the


                                       40
<PAGE>   46

      rate of return on assets or equity of such Lender (or any Applicable
      Lending Office) to a level below that which such Lender (or any Applicable
      Lending Office) could have achieved but for such Regulatory Change.

            (c) Without limiting the effect of the other provisions of this
      Section (but without duplication), in the event that any Regulatory Change
      or the compliance by the Agent or any Lender therewith shall (i) impose,
      modify, or hold applicable any reserve, special deposit, or similar
      requirement against any Letter of Credit or obligation to issue Letters of
      Credit, or (ii) impose upon the Agent or such Lender any other condition
      regarding any Letter of Credit or obligation to issue Letters of Credit,
      and the result of any such event shall be to increase the cost to the
      Agent or such Lender of issuing or maintaining any Letter of Credit or
      obligation to issue Letters of Credit or any liability with respect to
      Letter of Credit Payments, or to reduce any amount receivable in
      connection therewith, then, within five Business Days of receipt of the
      certificate provided for in Section 2.22(e), the Borrowers shall pay to
      the Agent or such Lender, as the case may be, from time to time as
      specified by the Agent or such Lender, the additional amounts indicated in
      such certificate as sufficient to compensate the Agent or such Lender for
      such increased cost or reduced amount receivable.

            (d) Without limiting the effect of the other provisions of this
      Section (but without duplication), the Borrowers shall pay to the Agent
      and each Lender such amounts as shall be indicated in such certificate as
      sufficient to compensate them for any loss, cost, or expense incurred by
      and as a result of:

                  (i) any payment, prepayment, or conversion by the Borrowers of
      a LIBO Rate Loan on a date other than the last day of an Interest Period
      for such Loan; or

                  (ii) any failure by the Borrowers to borrow a LIBO Rate Loan
      or to convert a Base Rate Loan into a LIBO Rate Loan on the date for such
      borrowing or conversion specified in the relevant Borrowing Request;

such compensation to include with respect to any LIBO Rate Loan, an amount equal
to the excess, if any, of (A) the amount of interest which would have accrued on
the principal amount so paid, prepaid, converted, or not borrowed or converted
for the period from the date of such payment, prepayment, conversion, or failure
to borrow or convert to the last day of the then current Interest Period for
such Loan (or, in the case of a failure to borrow or convert, the Interest
Period for such Loan which would have commenced on the date of such failure to
borrow or convert) at the applicable rate of interest for such Loan provided for
herein over (B) the interest component of the amount the Agent or such Lender
bid in the London interbank market in respect of such Loan for Dollar deposits
of amounts comparable to such principal amount and maturities comparable to such
period, as reasonably determined by the Agent or such Lender.

            (e) Determinations by the Agent or any Lender for purposes of this
      Section of the effect of any Regulatory Change on capital maintained, its
      costs or rate of return, maintaining Loans, issuing Letters of Credit, its
      obligation to make Loans and issue Letters of Credit, or


                                       41
<PAGE>   47

      on amounts receivable by it in respect of Loans, Letters of Credit, or
      such obligations, and the additional amounts required to compensate the
      Agent and such Lender under this Section shall be conclusive, absent
      manifest error, provided that such determinations are made on a reasonable
      basis. The Agent or the relevant Lender shall furnish the Borrowers with a
      certificate setting forth in reasonable detail the basis and amount of
      increased costs incurred or reduced amounts receivable as a result of any
      such event, and the statements set forth therein shall be conclusive,
      absent manifest error. The Agent or the relevant Lender shall (i) notify
      the Borrowers, as promptly as practicable after the Agent or such Lender
      obtains knowledge of any Additional Costs or other sums payable pursuant
      to this Section and determines to request compensation therefor, in
      respect of any event occurring after the Closing Date which will entitle
      the Agent or such Lender to compensation pursuant to this Section;
      provided that the Borrowers shall not be obligated for the payment of any
      Additional Costs or other sums payable pursuant to this Section to the
      extent such Additional Costs or other sums accrued more than 90 days prior
      to the date upon which the Borrowers were given such notice; and (ii)
      designate a different Applicable Lending Office for the Loans affected by
      such event if such designation will avoid the need for or reduce the
      amount of such compensation and will not, in the sole opinion of the Agent
      or such Lender, be disadvantageous to the Agent or such Lender. Any
      compensation requested by the Agent or any Lender pursuant to this Section
      shall be due and payable within five Business Days of delivery of any such
      notice to the Borrowers.

      2.23 Illegality. Notwithstanding any other provision of this Agreement, in
the event that it becomes unlawful for any Lender or its Applicable Lending
Office to (a) honor its obligation to make LIBO Rate Loans, or (b) maintain LIBO
Rate Loans, then such Lender shall promptly notify the Agent and the Borrowers
thereof. The obligation of such Lender to make LIBO Rate Loans and convert Base
Rate Loans into LIBO Rate Loans shall then be suspended until such time as such
Lender may again make and maintain LIBO Rate Loans, and the outstanding LIBO
Rate Loans of such Lender shall be converted into Base Rate Loans in accordance
with Section 2.14; provided, however, each Lender shall use reasonable efforts
to designate a different Applicable Lending Office with respect to any LIBO Rate
Loan affected by the matters or circumstances described in this Section to avoid
the results provided in this Section if possible, so long as such designation is
not disadvantageous to the Lenders as determined by them in their sole
discretion.

      2.24 Taxes.

            (a) All payments made by the Borrowers under this Agreement shall be
      made free and clear of, and without reduction or withholding for or on
      account of, present or future income, stamp or other taxes, levies,
      imposts, duties, charges, fees, deductions or withholdings, hereafter
      imposed, levied, collected, withheld or assessed by any Governmental
      Authority on the basis of any change after the date hereof in any
      applicable treaty, law, rule, guideline or regulations or in the
      interpretation or administration thereof, excluding, in the case of the
      Agent and each Lender, income and franchise taxes (whether based upon net
      income, capital or profits) imposed on the Agent or such Lender (all such
      non-excluded taxes, levies, imposts, deductions, charges or withholdings
      being hereinafter called "Taxes"). If any Taxes are required to be
      withheld from any amounts payable to the


                                       42
<PAGE>   48

      Agent or any Lender hereunder or under any other Loan Document, the
      amounts so payable to the Agent or such Lender shall be increased to the
      extent necessary to yield to the Agent or such Lender (after payment of
      all Taxes) interest or any such other amounts payable hereunder at the
      rates or in the amounts specified in this Agreement and the other Loan
      Documents. Whenever any Taxes are payable by the Borrowers, promptly
      thereafter the Borrowers shall send to the Agent for its own account or
      for the account of such Lender, as the case may be, a certified copy of an
      original official receipt received by the Borrowers showing payment
      thereof. If any Borrower fails to pay any Taxes when due to the
      appropriate taxing authority or fails to remit to the Agent the required
      receipts or other required documentary evidence, such Borrower shall
      indemnify the Agent and the Lenders for any incremental taxes, interest or
      penalties that may become payable by the Agent or any Lender as a result
      of any such failure. The agreements in this Section shall survive the
      termination of this Agreement and the payment of all Obligations.

            (b) Each Lender that is not incorporated under the laws of the
      United States of America or a state thereof agrees that, on the date
      hereof or, if it becomes a Lender in accordance with Section 9.1, on the
      date of the applicable Assignment Agreement, it will, to the extent it may
      lawfully do so, deliver to the Borrowers and the Agent two duly completed
      copies of United States Internal Revenue Service Form W-8, 1001 or 4224 or
      any other applicable form, as the case may be, certifying in each case
      that such Lender is entitled to receive payments under any Loan Document,
      without deduction or withholding of any United States federal income
      taxes. At the written request of the Borrowers, each Lender which delivers
      to the Borrowers and the Agent a form pursuant to the preceding sentence
      further undertakes to deliver to the Borrowers and the Agent two further
      copies of such form, or successor applicable forms, or other manner of
      certification, as the case may be, on or before the date that any such
      letter or form expires or becomes obsolete or after the occurrence of any
      event requiring a change in the most recent form previously delivered by
      it to the Borrowers, and such extensions or renewals thereof as may
      reasonably be requested by the Borrowers, certifying in the case of each
      such form that such Lender is entitled to receive payments under any Loan
      Document without deduction or withholding of any United States federal
      income taxes, unless in any such case, an event (including any change in
      treaty, law or regulation) has occurred prior to the date on which any
      such delivery would otherwise be required which renders all such forms
      inapplicable or which would prevent such Lender from duly completing and
      delivering any such form with respect to it and such Lender advises the
      Borrowers that it is not capable of receiving payments without any
      deduction or withholding of United States federal income tax.

      2.25 Replacement Lenders.

            (a) If any Lender (i) has notified the Borrowers of its incurring
      additional costs under Section 2.22 or the illegality of LIBO Rate Loans
      under Section 2.23, (ii) has required the Borrowers to make payments for
      Taxes under Section 2.24, or (iii) has informed any Borrower of a
      Regulatory Change in accordance with Section 2.26, or if any Tranche A
      Lender is not in agreement with the amount of any Borrowing Base
      redetermination which a group of Tranche A Lenders constituting at least
      the Tranche A Required Lenders has


                                       43
<PAGE>   49

      approved, or if any Tranche B Lender is not in agreement with the amount
      of any Tranche B Borrowing Base redetermination which a group of Tranche B
      Lenders constituting at least the Tranche B Required Lenders has approved,
      then in any such event the Borrowers may, unless such Lender has notified
      the Borrowers that the circumstances giving rise to such notice no longer
      apply, terminate, in whole but not in part, the Commitments or the Tranche
      B Commitment of such Lender (other than the Agent) (the "Terminated
      Lender") at any time upon five Business Days' prior written notice to the
      Terminated Lender and the Agent (such notice referred to herein as a
      "Notice of Termination").

            (b) In order to effect the termination of the Commitments or the
      Tranche B Commitment of the Terminated Lender, the Borrowers shall (i)
      obtain an agreement with one or more Lenders to increase their Commitments
      and/or become a Tranche B Lender (ii) request any one or more other
      banking institutions to become a "Lender" in place and instead of such
      Terminated Lender and agree to accept its Commitments; provided, however,
      that such one or more other banking institutions are reasonably acceptable
      to the Agent and become parties by executing an Assignment Agreement (the
      Lenders or other banking institutions that agree to accept in whole or in
      part the Commitments or the Tranche B Commitment of the Terminated Lender
      being referred to herein as the "Replacement Lenders"), such that the
      aggregate increased and/or accepted Total Facility Amounts of the
      Replacement Lenders under clauses (i) and (ii) above equal the Tranche A
      Facility Amount and the Tranche B Facility Amount (if any) of the
      Terminated Lender and provided further, no Person may become a Tranche B
      Lender hereunder unless such Person also is or becomes a Tranche A Lender.

            (c) The Notice of Termination shall include the name of the
      Terminated Lender, the date the termination will occur (the "Termination
      Date"), the Replacement Lender or Replacement Lenders to which the
      Terminated Lender will assign its Commitments or the Tranche B Commitment,
      and, if there will be more than one Replacement Lender, the portion of the
      Terminated Lender's Commitments or the Tranche B 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 Agreement assign its Commitments

or a category of extensions of credit or other assets of such Lender which
includes any LIBO Rate Loan, or (b) becomes subject to restrictions on the
amount of such a category of liabilities or assets which it may hold, then, at
the election of such Lender with notice to the Agent and the Borrowers setting
forth in reasonable detail a calculation of such Additional Costs or a
description of such restrictions, the obligation of such Lender to make LIBO
Rate Loans and to convert Base Rate Loans into LIBO Rate Loans shall be
suspended until such time as such Regulatory Change or other circumstance ceases

      other public officials incurred or to be incurred in connection with the
      filing and recordation of any Security Instruments, for which invoices

      3.3 Conditions Precedent to Issuance of Letters of Credit. The obligation
of the Agent, as the issuer of the Letters of Credit, to issue, renew, or extend
any Letter of Credit is subject to the satisfaction of the following additional
conditions precedent:

<PAGE>   54

            (a) the Borrowers shall have delivered to the Agent a written (or

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

      To induce the Agent and the Lenders to enter into this Agreement and to
extend credit to the Borrowers, each Borrower represents and warrants to the
Agent and each Lender (which representations and warranties shall survive the
delivery of the Notes) that:

      4.1 Due Authorization. The execution and delivery by the Borrowers of this
Agreement and the borrowings hereunder, the execution and delivery by the
Borrowers of the Notes and the other Loan Documents, the repayment of the Notes
and interest and fees provided for in the Notes and this Agreement, and the
performance of all obligations of the Borrowers under the Loan Documents are
within the power of the Borrowers, have been duly authorized by all necessary
corporate action by the Borrowers, and do not and will not (a) require the
consent of any Governmental Authority to be obtained by any Borrower, (b)
contravene or conflict with any Requirement of Law applicable to any Borrower or
the articles or certificate of incorporation, bylaws, or other organizational or
governing documents of the Borrowers, (c) contravene or conflict with any
material indenture, instrument, or other agreement, or any indenture,
instrument, or other agreement that, when aggregated with other such agreements,
is material, to which any Borrower is a party or by which any Property of any
Borrower may be presently bound or encumbered, except as could not reasonably be
expected to have a Material Adverse Effect, (d) contravene or conflict with any
indenture, instrument, or other agreement by which any item of Collateral is
bound or to which any such item of Collateral is subject, except as could not
reasonably be expected to have a Material Adverse Effect, or (e) result in or
require the creation or imposition of any Lien in, upon or of any Property of
any Borrower under any such indenture, instrument, or other agreement, other
than the Loan Documents.

      4.2 Corporate Existence. Each Borrower is a corporation duly organized,
legally existing, and in good standing under the laws of its state of
incorporation and is duly qualified as a foreign corporation and is in good
standing in all jurisdictions wherein the ownership of Property or the


                                       49
<PAGE>   55

operation of its business necessitates same, other than those jurisdictions
wherein the failure to so qualify will not have a Material Adverse Effect.

      4.3 Valid and Binding Obligations. All Loan Documents to which each
Borrower is a party, when duly executed and delivered by such Borrower, will be
the legal, valid, and binding obligations of the Borrower, enforceable against
such Borrower in accordance with its respective terms except as limited by
bankruptcy, insolvency or similar laws affecting generally the rights of
creditors and general principles of equity, whether applied by a court of law or
equity.

      4.4 Existing Indebtedness; No Defenses. As of the date hereof, (a) the
Borrowers are indebted in the aggregate principal amounts set forth in Exhibit X
under the heading "Existing Indebtedness", and (b) the Borrowers have no
defenses to, rights of setoff against, claims or counterclaims with respect to,
and no default exists under or with respect to any Indebtedness or obligation of
the Borrowers evidenced thereby.

      4.5 Security Instruments. The provisions of each Security Instrument
executed by any Borrower or any Substitute Mortgagor are effective to create in
favor of the Agent or the Collateral Agent, a legal, valid, and enforceable Lien
in all right, title, and interest of such Person in the Collateral described
therein, which Liens, assuming the accomplishment of recording and filing in
accordance with applicable laws prior to the intervention of rights of other
Persons, shall constitute fully perfected first-priority Liens on all right,
title, and interest of such Person in the Collateral described therein except
for Permitted Liens.

      4.6 Title to Assets. Except as heretofore disclosed to the Agent in
writing, insofar as such Property constitutes real property or interests in real
property, each of the Borrowers has good and indefeasible title to all of its
Mortgaged Properties and all of its other Properties which are material, free
and clear of Liens, except Permitted Liens. With respect to Property which does
not constitute real property or an interest in real property, each of the
Borrowers owns all such other Properties which are material, free and clear of
all Liens, except Permitted Liens and Liens otherwise permitted under Section
6.3.

      4.7 Scope and Accuracy of Financial Statements. The Financial Statements
of the Guarantor and its Subsidiaries as of December 31, 1997 and September 30,
1998 (subject, in the case of the Financial Statements as of September 30, 1998,
to normal year-end audit adjustments), present fairly the financial position and
results of operations and cash flows of the Guarantor and its Subsidiaries in
accordance with GAAP as at the relevant point in time or for the period
indicated, as applicable. No event or circumstance has occurred since September
30, 1998, except for the material decline of oil and gas prices generally, which
could reasonably be expected to have a Material Adverse Effect.

      4.8 No Material Misstatements. All written estimates, projections and
forecasts furnished by or on behalf of the Borrowers or the Guarantor to the
Agent or any of the Lenders for purposes of or in connection with this
Agreement, or in connection with any extension of credit hereunder, were and
will be prepared on the basis of the good faith estimate of the Borrowers'
senior management concerning probable financial condition and performance based
on assumptions, data,


                                       50
<PAGE>   56

tests or conditions believed to be reasonable or to represent industry
conditions existing at the time such estimates, projections or forecasts were
made. No other information, exhibit, statement, or report furnished to the Agent
or any Lender by or at the direction of the Borrowers or the Guarantor in
connection with this Agreement contains any material misstatement of fact or
omits to state a material fact or any fact necessary to make the statements
contained therein, in light of the circumstances in which they were made, not
misleading as of the date made or deemed made.

      4.9 Liabilities and Litigation. Other than as listed under the heading
"Liabilities" on Exhibit X, none of the Borrowers or the Guarantor has any
liabilities, direct, or contingent, which could reasonably be expected to have a
Material Adverse Effect. Except as set forth under the heading "Litigation" on
Exhibit X, no litigation or other action of any nature is pending before any
Governmental Authority or, to the best knowledge of such Borrowers, threatened,
against or affecting (a) any Collateral, or, in the case of Environmental Laws,
any Property of any Borrower or any real Property of the Guarantor, or the
facilities located and the operations conducted thereon, which, if determined
adversely to such Borrower or the Guarantor, could reasonably be expected to
have a Material Adverse Effect, (b) any Borrower's or the Guarantor's ability to
enter into, execute, deliver or perform in any material respect its obligations
under the Loan Documents, (c) any Borrower or the Guarantor which, if determined
adversely to such Borrower or the Guarantor, could reasonably be expected to
result in any judgment or liability, individually or when aggregated with all
other such judgments or liabilities, which could reasonably be expected to have
a Material Adverse Effect and which is not fully covered by insurance (exclusive
of any deductible amount related to such insurance, which deductible amount is
customary for Persons engaged in similar businesses), or (d) any Borrower or the
Guarantor, which if determined adversely to such Borrower or the Guarantor,
could reasonably be expected to result in any other Material Adverse Effect.

      4.10 Authorizations; Consents. Except as expressly contemplated by this
Agreement, no authorization, consent, approval, exemption, franchise, permit, or
license of, or filing with, any Governmental Authority or any other Person is
required to be obtained by any Borrower to authorize, or is otherwise required
in connection with, the valid execution and delivery by the Borrowers of the
Loan Documents or any instrument contemplated hereby, the repayment by the
Borrowers of the Notes and interest and fees provided in the Notes and this
Agreement, or the performance by the Borrowers of the Obligations.

      4.11 Compliance with Laws. Each Borrower and its Property, are in
compliance with all applicable Requirements of Law, including Environmental
Laws, the Natural Gas Policy Act of 1978, as amended, and ERISA, other than any
Requirements of Laws the failure with which to comply, individually or in the
aggregate, could reasonably be expected not to cause a Material Adverse Effect.

      4.12 Default. Neither any Borrower nor the Guarantor is in default of, and
no event has occurred which, with the lapse of time or giving of notice, or
both, could result in such a default of, (i) any charter document or bylaws of
any Borrower or the Guarantor, or (ii) any agreement or obligation other than an
agreement or obligation evidencing or relating to Debt to which any Borrower or
the Guarantor is a party or by which any Property of any Borrower or the
Guarantor may be bound, pursuant to which the obligations of the Borrowers and
the Guarantor in the


                                       51
<PAGE>   57

aggregate under any such agreement or obligation, or the obligations secured
thereby, exceed $2,500,000, except such as are being contested in good faith and
as to which such reserve as may be required by GAAP shall have been made
therefore.

      4.13 ERISA. No Reportable Event has occurred with respect to any Single
Employer Plan, and each Single Employer Plan has complied with and been
administered in all material respects in accordance with applicable provisions
of ERISA and the Code. To the best knowledge of the Borrowers, (a) no Reportable
Event has occurred with respect to any Multiemployer Plan, and (b) each
Multiemployer Plan has complied with and been administered in all material
respects with applicable provisions of ERISA and the Code. Each Plan satisfied
the minimum funding requirements under ERISA and the Code as of the last annual
valuation date applicable thereto. Neither the Borrowers nor any Commonly
Controlled Entity has had a complete or partial withdrawal from any
Multiemployer Plan for which there is any withdrawal liability. As of the most
recent valuation date applicable to any Multiemployer Plan, neither the
Borrowers nor any Commonly Controlled Entity would become subject to any
liability under ERISA if the Borrower or such Commonly Controlled Entity were to
withdraw completely from such Multiemployer Plan. Neither any Borrower nor any
Commonly Controlled Entity has received notice that any Multiemployer Plan is
Insolvent or in Reorganization. To the best knowledge of the Borrowers, no such
Insolvency or Reorganization which could reasonably be expected to have a
Material Adverse Effect is likely to occur. Based upon GAAP existing as of the
date of this Agreement and current factual circumstances, the Borrowers have no
reason to believe that the annual cost during the term of this Agreement to the
Borrowers and all Commonly Controlled Entities for post-retirement benefits to
be provided to the current and former employees of the Borrowers and all
Commonly Controlled Entities under Plans which are welfare benefit plans (as
defined in Section 3(1) of ERISA) will, in the aggregate, have a Material
Adverse Effect.

      4.14 Environmental Laws. To the best knowledge and belief of the
Borrowers, except for matters listed below in this Section 4.14 which could not
reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect, and except as described on Exhibit X under the heading
"Environmental Matters:"

            (a) no Property of any Borrower or real Property of the Guarantor is
      currently on or has ever been on, any federal or state list of Superfund
      Sites;

            (b) no Hazardous Substances have been generated, transported, and/or
      disposed of by any Borrower or the Guarantor at a site which was, at the
      time of such generation, transportation, and/or disposal, or has since
      become, a Superfund Site;

            (c) except in accordance with applicable Requirements of Law or the
      terms of a valid permit, license, certificate, or approval of the relevant
      Governmental Authority, no Release of Hazardous Substances has occurred by
      any Borrower or the Guarantor from, affecting, or related to any Property
      of any Borrower or any real Property of the Guarantor or the facilities
      located and the operations conducted thereon; and


                                       52
<PAGE>   58

            (d) no Environmental Complaint has been received by any Borrower or
      the Guarantor.

      4.15 Compliance with Federal Reserve Regulations. No transaction
contemplated by the Loan Documents is in violation of any regulations
promulgated by the Board of Governors of the Federal Reserve System, including
Regulations G, T, U, or X.

      4.16 Investment Company Act Compliance. None of the Borrowers is, nor is
any Borrower directly or indirectly controlled by or acting on behalf of any
Person which is, an "investment company" or an "affiliated person" of an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

      4.17 Public Utility Holding Company Act Compliance. No Borrower is a
"holding company," or an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company," within the meaning of the Public Utility
Holding Company Act of 1935, as amended.

      4.18 Proper Filing of Tax Returns; Payment of Taxes Due. Each Borrower has
duly and properly filed its United States income tax returns and all other tax
returns which are required to be filed and has paid all taxes shown to be due
thereon, except such as are being contested in good faith and as to which
adequate provisions and disclosures have been made and except such returns of
which the failure to file has not had or would not have a Material Adverse
Effect. The respective charges and reserves on the books of each Borrower with
respect to taxes and other governmental charges are adequate.

      4.19 Refunds. Except as described on Exhibit X under the heading

material portion of the proceeds received or to be received from the sale of
hydrocarbons constituting part of the Mortgaged Property.

      4.20 Gas Contracts. Except as described on Exhibit X under the heading
"Gas Contracts," as of the Closing Date, (a) no Borrower is obligated in any

deliver hydrocarbons produced from or allocated to any of the Mortgaged Property
at some future date without receiving full payment therefor within 90 days of
delivery, and (b) no Borrower has produced gas, in any material amount, subject

the validity or effectiveness of any such Intellectual Property; and each
Borrower knows of no valid basis for any such claim. The use of such

likely to have a Material Adverse Effect.

"Labor Matters," as of the Closing Date there are no collective bargaining

Governmental Authority, riot, activities of armed forces, or acts of God.

from such Borrower in favor of the Agent have been filed.

on the part of the Agent, the Collateral Agent, or any Lender or any of their
respective shareholders, officers, directors, employees, agents,

inaction of any Person to be indemnified subsequent to the exercise of ownership
rights or the taking of any foreclosure action with respect to any of the
Collateral and with respect to such Collateral such claim, loss, damage,
liability, fine, penalty, charge, proceeding, order, judgment, action or
requirement arises subsequent to the exercise of ownership rights or the taking
of any foreclosure action with respect to such Collateral, to the extent such
Person is a "person in control" under any Environmental Law. The foregoing
indemnity shall survive satisfaction of all Obligations and the termination of
this Agreement, unless all such Obligations have been satisfied wholly in cash
from the Borrowers and not by way of realization against any Collateral or the
conveyance of any Property in lieu thereof.

      instituted by any Governmental Authority against any Borrower or the
      Guarantor under the Racketeering Influence and Corrupt Organizations
      Statute (18 U.S.C. ss.1961 et seq.), the result of which could reasonably

      such Borrower or the Guarantor subject to a Lien in favor of the Agent
      without (i) satisfaction or provision for satisfaction of such Lien, or
      (ii) such forfeiture or transfer of such Property being expressly made

      its Property, with intent to hinder, delay, or defraud its creditors or
      any of them;

      Reportable Event shall occur with respect to, or proceedings shall
      commence to have a trustee appointed, or a trustee shall be appointed, to
      administer or to terminate, any Single Employer Plan, which Reportable

      shall terminate for purposes of Title IV of ERISA; any Borrower, the
      Guarantor, or any Commonly Controlled Entity shall incur, or in the
      reasonable opinion of the Agent, be likely to incur any liability in
      connection with a withdrawal from, or the Insolvency or Reorganization of,
      a Multiemployer Plan; or any other event or condition shall occur or exist
      with respect to a Plan and the result of such events or conditions
      referred to in this Section 7.1(l) could reasonably be expected to subject
      such Borrower, the Guarantor or any Commonly Controlled Entity to any tax
      (other than an excise tax under Section 4980 of the Code), penalty or
      other liabilities which taken in the aggregate would have a Material

      provided the Agent, within 30 days following written notice to the
      Borrowers from the Agent, with additional Collateral having at least an

                                       66

                                  ARTICLE VIII

                                    THE AGENT

      8.1 Appointment. Each Lender hereby designates and appoints CIBC as the
Agent and CIBC Inc. as the Collateral Agent under this Agreement and the other
Loan Documents. Each Lender authorizes the Agent and the Collateral Agent to
take such action on behalf of such Lender under the provisions of this Agreement
and the other Loan Documents and to exercise such powers and perform such duties
as are expressly delegated to the Agent and the Collateral Agent by the terms of
this Agreement and the other Loan Documents, together with such other powers as
are reasonably incidental thereto. Notwithstanding any provision to the contrary
elsewhere in this Agreement or in any other Loan Document, neither the Agent nor
the Collateral Agent shall have any duties or responsibilities except those
expressly set forth herein or in any other Loan Document or any fiduciary
relationship with any Lender; and no implied covenants, functions,
responsibilities, duties, obligations, or liabilities on the part of the Agent
or the Collateral Agent shall be read into this Agreement or any other Loan
Document or otherwise exist against the Agent or the Collateral Agent.

      8.2 Delegation of Duties. Each of the Agent and the Collateral Agent may
execute any of its duties under this Agreement and the other Loan Documents by
or through agents or attorneys-in-fact and shall be entitled to advice of
counsel concerning all matters pertaining to such duties. Neither the Agent nor
the Collateral Agent shall be responsible for the negligence or misconduct of
any agents or attorneys-in-fact selected by it with reasonable care.

      8.3 Exculpatory Provisions. Neither the Agent, the Collateral Agent, nor
any of their respective officers, directors, employees, agents,
attorneys-in-fact or affiliates shall be (a) required to initiate or conduct any
litigation or collection proceedings hereunder, except with the concurrence of
the Required Lenders and contribution by each Lender of its Percentage Share of
costs reasonably expected by the Agent or the Collateral Agent to be incurred in
connection therewith, (b) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except for gross negligence or willful misconduct of the
Agent, the Collateral Agent, or such Person), or (c) responsible in any manner
to any Lender for any recitals, statements, representations or warranties made
by the Borrowers or any officer thereof contained in this Agreement or any other
Loan Document or in any certificate, report, statement or other document
referred to or provided for in, or received by the Agent or the Collateral Agent
under or in connection with, this Agreement or any other Loan Document, or for
the value, validity, effectiveness, genuineness, enforceability or sufficiency
of this Agreement or any other Loan Document or for any failure of the Borrower
to perform its obligations hereunder or thereunder. Neither the Agent nor the
Collateral Agent shall 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 the Borrowers.

      8.4 Reliance by Agent. Each of the Agent and the Collateral Agent shall be
entitled to rely, and shall be fully protected in relying, upon any Note,
writing, resolution, notice, consent,


                                       68
<PAGE>   74

certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document or conversation believed by it to be
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 counsel to
the Borrowers), independent accountants and other experts selected by the Agent
or the Collateral Agent. Each of the Agent and the Collateral Agent may deem and
treat the payee of any Note as the owner thereof for all purposes unless and
until a written notice of assignment, negotiation, or transfer thereof shall
have been received by the Agent. Each of the Agent and the Collateral Agent
shall be fully justified in failing or refusing to take any action under this
Agreement or any other Loan Document unless it shall first receive such advice
or concurrence of the Required Lenders as it deems appropriate or of all of the
Lenders if required by any provision of this Agreement and contribution by each
Lender of its Percentage Share of costs reasonably expected by the Agent or the
Collateral Agent, as the case may be, to be incurred in connection therewith.
Each of the Agent and the Collateral Agent shall in all cases be fully protected
in acting, or in refraining from acting, under this Agreement and the other Loan
Documents in accordance with a request of the Required Lenders. Such request and
any action taken or failure to act pursuant thereto shall be binding upon the
Lenders and all future holders of the Notes. In no event shall either the Agent
or the Collateral Agent be required to take any action that exposes such agent
to personal liability or that is contrary to any Loan Document or applicable
Requirement of Law.

      8.5 Notice of Default. Neither the Agent nor the Collateral Agent shall be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default unless such agent has received notice from a Lender or the Borrowers
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default." In the event that such agent
receives such a notice, such agent shall promptly give notice thereof to the
Lenders. The Agent and the Collateral Agent shall take such action with respect
to such Default or Event of Default as shall be reasonably directed by the
Required Lenders; provided that unless and until the Agent and the Collateral
Agent shall have received such directions, subject to the provisions of Section
7.2, each of the Agent and the Collateral Agent may (but shall not be obligated
to) take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable in the best interests of
the Lenders. In the event that the officer of the Agent or the Collateral Agent
primarily responsible for the lending relationship with the Borrowers or the
officer of any Lender primarily responsible for the lending relationship with
the Borrowers becomes aware that a Default or Event of Default has occurred and
is continuing, such agent or such Lender, as the case may be, shall use its good
faith efforts to inform the other Lenders and/or the other agents, as the case
may be, promptly of such occurrence. Notwithstanding the preceding sentence,
failure to comply with the preceding sentence shall not result in any liability
to the Agent, the Collateral Agent, or any Lender.

      8.6 Non-Reliance on Agent and Other Lenders. Each Lender expressly
acknowledges that neither the Agent, the Collateral Agent, any other Lender nor
any of their respective officers, directors, employees, agents,
attorneys-in-fact or affiliates has made any representation or warranty to such
Lender and that no act by the Agent, the Collateral Agent, or any other Lender
hereafter taken, including any review of the affairs of the Borrowers, shall be
deemed to constitute any representation or warranty by the Agent, the
Collateral Agent, or any Lender to any other Lender. Each Lender represents to
the Agent and the Collateral Agent that it has, independently and without reli-


                                       69
<PAGE>   75

ance upon the Agent, the Collateral Agent, 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,
condition (financial and otherwise) and creditworthiness of the Borrowers and
the value of the Collateral and other Properties of the Borrowers and has made
its own decision to enter into this Agreement. Each Lender also represents that
it will, independently and without reliance upon the Agent or the Collateral
Agent or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own 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, condition (financial
and otherwise) and creditworthiness of the Borrowers and the value of the
Collateral and other Properties of the Borrowers. Except for notices, reports
and other documents expressly required to be furnished to the Lenders by the
Agent or the Collateral Agent hereunder, neither the Agent nor the Collateral
Agent shall have any duty or responsibility to provide any Lender with any
credit or other information concerning the business, operations, property,
condition (financial and otherwise), or creditworthiness of the Borrowers or the
value of the Collateral or other Properties of the Borrowers which may come into
the possession of the Agent, the Collateral Agent or any of their respective
officers, directors, employees, agents, attorneys-in-fact or affiliates.

      8.7 Indemnification. EACH LENDER AGREES TO INDEMNIFY THE AGENT AND THE
COLLATERAL AGENT AND EACH OF THEIR OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
ATTORNEYS-IN-FACT AND AFFILIATES (TO THE EXTENT NOT REIMBURSED BY THE BORROWERS
AND WITHOUT LIMITING THE OBLIGATION OF THE BORROWERS TO DO SO), RATABLY
ACCORDING TO THE PERCENTAGE SHARE OF SUCH LENDER, FROM AND AGAINST ANY AND ALL
LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND WHATSOEVER WHICH
MAY AT ANY TIME (INCLUDING ANY TIME FOLLOWING THE PAYMENT AND PERFORMANCE OF ALL
OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT) BE IMPOSED ON, INCURRED BY OR
ASSERTED AGAINST THE AGENT, THE COLLATERAL AGENT OR ANY OF THEIR RESPECTIVE
OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES IN ANY
WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR
ANY OTHER DOCUMENT CONTEMPLATED OR REFERRED TO HEREIN OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR ANY ACTION TAKEN OR OMITTED BY THE AGENT, THE COLLATERAL
AGENT OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
ATTORNEYS-IN-FACT OR AFFILIATES UNDER OR IN CONNECTION WITH ANY OF THE
FOREGOING, INCLUDING ANY LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES,
PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS IMPOSED,
INCURRED OR ASSERTED AS A RESULT OF THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT,
OF THE AGENT, THE COLLATERAL AGENT OR ANY OF THEIR RESPECTIVE OFFICERS,
DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES; PROVIDED THAT NO
LENDER SHALL BE LIABLE FOR THE PAYMENT OF ANY PORTION OF SUCH LIABILITIES,
OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS,
EXPENSES OR DISBURSEMENTS RESULTING SOLELY FROM THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF THE AGENT, THE COLLATERAL AGENT OR ANY OF THEIR RESPECTIVE
OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES. THE
AGREEMENTS IN THIS SECTION


                                       70
<PAGE>   76

SHALL SURVIVE THE PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION
OF THIS AGREEMENT.

      8.8 Restitution. Should the right of the Agent, the Collateral Agent or
any Lender to realize funds with respect to the Obligations be challenged and
any application of such funds to the Obligations be reversed, whether by
Governmental Authority or otherwise, or should the Borrowers otherwise be
entitled to a refund or return of funds distributed to the Lenders in connection
with the Obligations, the Agent, the Collateral Agent or such Lender, as the
case may be, shall promptly notify the Lenders of such fact. Not later than
Noon, Eastern Standard or Daylight Savings Time, as the case may be, of the
Business Day following such notice, each Lender shall pay to the Agent an amount
equal to the ratable share of such Lender of the funds required to be returned
to the Borrowers. The ratable share of each Lender shall be determined on the
basis of the percentage of the payment all or a portion of which is required to
be refunded originally distributed to such Lender, if such percentage can be
determined, or, if such percentage cannot be determined, on the basis of the
Percentage Share of such Lender. The Agent shall forward such funds to the
Borrowers or to the Lender required to return such funds. If any such amount due
to the Agent is made available by any Lender after Noon, Eastern Standard or
Daylight Savings Time, as the case may be, of the Business Day following such
notice, such Lender shall pay to the Agent (or the Lender required to return
funds to the Borrowers, as the case may be) for its own account interest on such
amount at a rate equal to the Federal Funds Rate for the period from and
including the date on which restitution to the Borrowers is made by the Agent
(or the Lender required to return funds to the Borrowers, as the case may be) to
but not including the date on which such Lender failing to timely forward its
share of funds required to be returned to the Borrowers shall have made its
ratable share of such funds available.

      8.9 Agents in Individual Capacity. Each of the Agent and the Collateral
Agent and their affiliates may make loans to, accept deposits from and generally
engage in any kind of business with the Borrowers as though the Agent and the
Collateral Agent were not agents hereunder. With respect to any Note issued to
the Lender serving as the Collateral Agent, the Collateral Agent shall have the
same rights and powers under this Agreement as a Lender and may exercise such
rights and powers as though it were not the Collateral Agent. The terms "Lender"
and "Lenders" shall include the Collateral Agent in its individual capacity.

      8.10 Successor Agent. Provided that a successor agent has been appointed
and has accepted such appointment as provided below, the Agent or the Collateral
Agent may resign upon 30 days' notice to the Lenders and the Borrowers. If the
Agent or the Collateral Agent shall resign as an agent under this Agreement and
the other Loan Documents, Lenders for which the Percentage Shares of Tranche A
Commitments aggregate at least sixty-six and two-thirds percent (66-2/3%) shall
appoint from among the Lenders a successor agent or collateral agent, as the
case may be, for the Lenders, whereupon such successor agent shall succeed to
the rights, powers and duties of such agent. The term "Agent" or "Collateral
Agent" shall mean such successor agent effective upon its appointment. Upon
written acceptance by such successor agent (a copy of which shall be furnished
to the Borrowers), the rights, powers, and duties of the former agent as Agent
or Collateral Agent shall be terminated, without any other or further act or
deed on the part of such former agent or any of the parties to this Agreement or
any holders of the Notes. After the resignation of the Agent or


                                       71
<PAGE>   77

the Collateral Agent hereunder as an agent, the provisions of this Article VIII
and Sections 2.2(d), 5.13, and 5.17 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was an agent under this Agreement
and the other Loan Documents.

      8.11 Applicable Parties. The provisions of this Article are solely for the
benefit of the Agent, the Collateral Agent and the Lenders, and the Borrowers
shall not have any rights as a third party beneficiary or otherwise or any
obligations under any of the provisions of this Article. In per forming
functions and duties hereunder and under the other Loan Documents, the Agent and
the Collateral Agent shall act solely as the agent of the Lenders and do not
assume, nor shall either be deemed to have assumed, any obligation or
relationship of trust or agency with or for the Borrowers or any legal
representative, successor, and assign of the Borrowers.

                                   ARTICLE IX

                                  MISCELLANEOUS

      9.1 Assignments; Participations.

            (a) The Borrowers may not assign any of their rights or obligations
      under any Loan Documents without the prior consent of the Agent and the
      Lenders.

            (b) With the consent of the Agent and the Borrowers (which consents
      shall not be unreasonably withheld), any Lender may assign to one or more
      assignees all or a portion of its rights and obligations under this
      Agreement pursuant to an Assignment Agreement; provided, however, that if
      the assigning Lender holds both Tranche A Loans and Tranche B Loans
      (and/or has a Tranche A Commitment and a Tranche B Commitment), then any
      assignment of any portion of the rights and obligations in respect of such
      Lender's Tranche B Loans and/or Tranche B Commitment or Tranche A Loans
      and/or Tranche A Commitment may only be made in conjunction with an
      assignment of a proportionate portion of its rights and obligations in
      respect of such Lender's Tranche A Loans and/or Tranche A Commitment or
      Tranche B Loans and/or Tranche B Commitment, respectively. Except with the
      consent of the Agent and the Borrowers (which consents shall not be
      unreasonably withheld) in the case of any assignment of any Tranche B
      Loans and/or Tranche B Commitment, any such assignment shall be in the
      amount of at least $10,000,000 in the case of a Tranche A assignment (or
      any whole multiple of $1,000,000 in excess thereof) and $1,000,000 in the
      case of a Tranche B assignment (or any whole multiple of $500,000 in
      excess thereof), and the assignee shall pay to the Agent a transfer fee in
      the amount of $3,500 for each such assignment. Any such assignment shall
      become effective upon the execution and delivery to the Agent of the
      Assignment Agreement and the consent of the Agent and the Borrowers.
      Promptly following receipt of an executed Assignment Agreement, the Agent
      shall send to the Borrowers a copy of such executed Assignment Agreement.
      Promptly following receipt of such executed Assignment Agreement, the
      Borrowers shall execute and deliver, at their own expense, new Notes to
      the assignee and, if applicable, the assignor, in accordance with their
      respective interests, whereupon the prior Notes of the assignor and, if
      applicable, the


                                       72
<PAGE>   78

      assignee, shall be canceled and returned to the Borrowers. Upon the
      effectiveness of any assignment pursuant to this Section 9.1(b), the
      assignee shall become a "Lender," if not already a "Lender," for all
      purposes of the Loan Documents, and the assignor shall be relieved of its
      obligations hereunder from and after the date of such assignment to the
      extent of such assignment. If the assignor no longer holds any rights or
      obligations under this Agreement, such assignor shall cease to be a
      "Lender" hereunder, except that its rights under Sections 2.21 and 5.18
      shall not be affected. On the last Business Day of each calendar quarter
      during which an assignment has become effective pursuant to this Section
      9.1(b), the Agent shall prepare a new Exhibit III giving effect to all
      such assignments effected during such month and will promptly provide a
      copy thereof to the Borrowers and each Lender.

            (c) Each Lender may transfer, grant, or assign participations in all
      or any portion of its interests hereunder to any Person pursuant to this
      Section 9.1(c), provided that such Lender shall remain a "Lender" for all
      purposes of this Agreement and the transferee of such participation shall
      not constitute a "Lender" hereunder. In the case of any such
      participation, the participant shall not have any rights under any Loan
      Document, the rights of the participant in respect of such participation
      to be against the granting Lender as set forth in the agreement with such
      Lender creating such participation, and all amounts payable by the
      Borrower hereunder shall be determined as if such Lender had not sold such
      participation. Each participation agreement shall provide that the Lender
      that has sold or granted the participation shall retain the sole right to
      take or refrain from taking any action under the Loan Documents, except
      that such participation agreement may provide that such Lender shall not,
      without the consent of the participant, agree to any amendment or waiver
      that would have the effect, to the extent any such amendment or waiver
      pertains to the type of Commitment(s) or Loan(s) of such participant so
      that such participant would be affected thereby, of (i) increasing the
      Commitments of such Lender, (ii) extending the Tranche A Commitment
      Termination Date, (iii) extending the Tranche B Commitment Termination
      Date, (iv) reducing the principal on the Loans, (v) reducing the rate of
      interest on the Loans or the Notes, (vi) reducing the amount of such
      Lender's participation in any fees payable pursuant to Sections 2.15 or
      2.16, or (vii) extending the time of scheduled payment of any Obligation,
      or (vii) releasing the Guaranty. All amounts payable to any Lender under
      Article 2 shall be determined as if such Lender had not sold any
      participations. Each agreement creating a participation must include an
      agreement by the participant to be bound by the provisions of Section 9.9.

            (d) The Lenders may furnish any information concerning the Borrowers
      in the possession of the Lenders from time to time to assignees and
      participants and prospective assignees and participants, provided that
      such Persons agree to be bound by the provisions of Section 9.9.

            (e) Notwithstanding anything in this Section to the contrary, any
      Lender may assign and pledge all or any of its Notes or any interest
      therein to any Federal Reserve Bank or the United States Treasury as
      collateral security pursuant to Regulation A of the Board of Governors of
      the Federal Reserve System and any operating circular issued by such
      Federal


                                       73
<PAGE>   79

      Reserve System and/or such Federal Reserve Bank. No such assignment or
      pledge shall release the assigning or pledging Lender from its obligations
      hereunder.

            (f) Each Lender party to this Agreement on the Closing Date hereby
      represents, and each Person that becomes a lender pursuant to an
      Assignment Agreement will represent, and shall be deemed to have
      represented on becoming a party to this Agreement, that it is a bank or
      other financial institution regularly engaged in making or purchasing
      loans, that it will make or acquire Loans hereunder for its own account in
      the ordinary course of its business, and that it has capital surplus and
      undivided profits aggregating at least $500,000,000.

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

      9.2 Survival of Representations, Warranties, and Covenants. All
representations and warranties of the Borrowers and all covenants and agreements
herein made shall survive the execution and delivery of the Notes and the
Security Instruments and shall remain in force and effect so long as any
Obligation is outstanding or any Commitments exist.

      9.3 Notices and Other Communications. Except as to oral notices expressly
authorized herein, which oral notices shall be confirmed in writing, all
notices, requests, and communications hereunder or in connection herewith or
with any other Loan Document shall be in writing (including by telecopy). Unless
otherwise expressly provided herein, any such notice, request, demand, or other
communication shall be deemed to have been duly given or made when delivered by
hand, or, in the case of delivery by mail, two Business Days after deposited in
the mail, certified mail, return receipt requested, postage prepaid, or, in the
case of telecopy notice, when receipt thereof is acknowledged orally or by
written confirmation report, addressed to each party at the "Address for
Notices" specified below its name on the signature pages hereof or at such other
address within the United States as shall be designated by such party in a
notice given to the Agent and the Borrowers.

      9.4 Parties in Interest. Subject to the restrictions on changes in
corporate structure set forth in Section 6.10 and other applicable restrictions
contained herein, all covenants and agreements herein contained by or on behalf
of the Borrowers, the Agent, the Collateral Agent or the Lenders shall be
binding upon and inure to the benefit of the Borrowers, the Agent, the
Collateral Agent or the Lenders, as the case may be, and their respective legal
representatives, successors, and permitted assigns.

      9.5 Rights of Third Parties. All provisions herein are imposed solely and
exclusively for the benefit of the Agent, the Collateral Agent the Lenders and
the Borrowers and their successors and permitted assigns. No other Person shall
have any right, benefit, priority, or interest hereunder or as a result hereof
or have standing to require satisfaction of provisions hereof in accordance with
their terms.


                                       74
<PAGE>   80

      9.6 No Waiver; Rights Cumulative. No course of dealing on the part of the
Agent, the Collateral Agent or the Lenders or their officers or employees, nor
any failure or delay by the Agent, the Collateral Agent or the Lenders with
respect to exercising any of their rights under any Loan Document shall operate
as a waiver thereof. The rights of the Agent, the Collateral Agent and the
Lenders under the Loan Documents shall be cumulative and the exercise or partial
exercise of any such right shall not preclude the exercise of any other right.
Neither the making of any Loan nor the issuance of a Letter of Credit shall
constitute a waiver of any of the covenants, warranties, or conditions of the
Borrowers contained herein. In the event any Borrower is unable to satisfy any
such covenant, warranty, or condition, neither the making of any Loan nor the
issuance of a Letter of Credit shall have the effect of precluding the Agent or
the Lenders from thereafter declaring such inability to be an Event of Default
as hereinabove provided.

      9.7 Severability. In the event any one or more of the provisions contained
in any of the Loan Documents shall, for any reason, be held to be invalid,
illegal, or unenforceable in any respect, such invalidity, illegality, or
unenforceability shall not affect any other provision of any Loan Document.

      9.8 Amendments; Waivers. Neither this Agreement nor any of the other Loan
Documents nor any terms hereof or thereof may be amended, supplemented,
modified, or waived except in writing and in accordance with the provisions of
this Section. The Agent and the Borrowers may, from time to time with the
written consent of the Required Lenders, enter into written amendments,
supplements, or modifications to the Loan Documents for the purpose of adding
any provisions to this Agreement or the other Loan Documents or changing in any
manner the rights of the Lenders or the Borrowers hereunder or thereunder or
waiving, on such terms and conditions as the Agent may specify in such
instrument, any of the requirements of this Agreement or the other Loan
Documents or any Default or Event of Default and its consequences; provided,
however, that no such amendment, supplement, modification, or waiver shall (a)
extend the time of scheduled payment of any Obligation, change the rate of
interest thereon, extend the Tranche A Commitment Termination Date, extend the
Tranche B Commitment Termination Date or extend a Final Maturity, reduce any fee
payable for the account of the Lenders hereunder, release any, all or
substantially all of the Collateral, release the Guaranty, reduce the amount of
any Obligation, increase the Tranche A Commitment Amount or increase the Tranche
B Commitment Amount, except in accordance with Section 2.12 change the Borrowing
Base or the Tranche B Borrowing Base or any other provision applicable to the
determination of the Borrowing Base, or the Tranche B Borrowing Base, or amend,
modify, or waive any provision of this Section or Sections 2.12, 5.13, 5.17 or
8.10, change the percentage specified in the definition of the Tranche A
Required Lenders or the Tranche B Required Lenders, or consent to the assignment
or transfer by the Borrowers of any of their rights or obligations under this
Agreement or the other Loan Documents, in any such case without the written
consent of all Lenders, (b) amend, modify, or waive any provision of Article
VIII or the rights or obligations of the Agent (including its rights and
obligations as issuer of the Letters of Credit) or the Collateral Agent without
the written consent of such agent, or (c) amend, modify, or waive any provision
relating to any Hedging Agreement without the written consent of the Lender
party thereto or whose affiliate is a party thereto. Any such amendment,
supplement, modification, or waiver shall apply equally to each of the Lenders
(taking into account the differences between the Tranche A Commitment and the
Tranche B Commitment) and shall be binding upon the Borrowers, the


                                       75
<PAGE>   81

Lenders, the Agent, and the Collateral Agent and all future holders of the
Notes. Notwithstanding the foregoing, during each Sales Period, the Collateral
Agent may, provided that no Default or Event of Default exists, release items of
Collateral sold by the Borrowers in accordance with Section 6.5. In the event of
any waiver, the Borrowers, the Lenders, the Agent, and the Collateral Agent
shall be restored to their respective former positions and rights hereunder and
under the other Loan Documents, and any Default or Event of Default waived shall
be deemed to be cured and not continuing; but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any right with respect
thereto.

      9.9 Confidentiality. In the event that any Borrower or the Guarantor
provides to the Agent, the Collateral Agent or the Lenders information belonging
to any Borrower or any Affiliate of the Borrowers, the Agent, the Collateral
Agent and the Lenders shall thereafter maintain such information in confidence.
This obligation of confidence shall not apply to such portions of the
information which (i) are in the public domain, (ii) hereafter become part of
the public domain without the Agent, the Collateral Agent or the Lenders
breaching their obligation of confidence herein or in any other Loan Document,
(iii) are previously known by the Agent, the Collateral Agent or the Lenders
from some source other than the Borrowers or any Affiliate of the Borrowers,
(iv) are hereafter developed by the Agent, the Collateral Agent or the Lenders
without using the information thus provided, (v) are hereafter obtained by or
available to the Agent, the Collateral Agent or the Lenders from a third party
who owes no obligation of confidence to the Borrowers or any Affiliate of the
Borrowers with respect to such information or through any other means other than
through disclosure by the Borrowers or any Affiliate of the Borrowers to the
Agent, the Collateral Agent or the Lenders, (vi) are disclosed with the
Borrowers' consent, (vii) must be disclosed pursuant to any Requirement of Law,
(viii) as may be required by law or regulation or order of any Governmental
Authority in any judicial, arbitration or governmental proceeding or (ix) as may
be requested by any Governmental Authority pursuant to any bank examination or
audit; provided, however, that to the extent practicable and unless otherwise
prohibited by any Requirement of Law, any Person disclosing any non-public
information pursuant to clauses (vii) or (viii) shall endeavor in good faith to
give the Borrowers at least 5 days' prior written notice of such disclosure.
Further, the Agent, the Collateral Agent or a Lender may disclose any such
information to any other Lender or successor agent, any independent petroleum
engineers or consultants, any independent certified public accountants, any
legal counsel employed by such Person in connection with this Agreement or any
other Loan Document, including the enforcement or exercise of all rights and
remedies hereunder or thereunder, or any assignee or participant (including
prospective assignees and participants) in the Loans; provided, however, that
the Agent, the Collateral Agent or the Lenders impose on the Person to whom such
information is disclosed the same obligation to maintain the confidentiality of
such information as is imposed upon it hereunder and such Person agrees to be
bound by the terms hereof. Notwithstanding anything to the contrary provided
herein, this obligation of confidence shall cease three (3) years from the later
of (a) the later to occur of the Final Maturity of the Tranche A Notes or the
Final Maturity of the Tranche B Notes or (b) the date that all Obligations are
paid or satisfied in full or otherwise performed or discharged or deemed
performed or discharged.

      9.10 Controlling Agreement. In the event of a conflict between the
provisions of this Agreement and those of any other Loan Document, this
Agreement shall control. Without limiting the generality of the foregoing, no
provision of any Letter of Credit Application, Security Instrument


                                       76
<PAGE>   82

or other agreement or document executed in connection herewith shall give the
Agent or any Lender any rights that are greater than the rights such Persons
have under this Agreement with respect to the same subject matter.

      9.11 Governing Law. THIS AGREEMENT AND THE NOTES AND THE GUARANTY SHALL BE
DEEMED TO BE CONTRACTS MADE UNDER AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO
PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAW.

      9.12 Jurisdiction and Venue. ALL ACTIONS OR PROCEEDINGS WITH RESPECT TO,
ARISING DIRECTLY OR INDIRECTLY IN CONNECTION WITH, OUT OF, RELATED TO, OR FROM
THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE LITIGATED, AT THE SOLE
DISCRETION AND ELECTION OF THE AGENT OR THE COLLATERAL AGENT, IN THE COURTS OF
THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN
DISTRICT OF NEW YORK. EACH BORROWER HEREBY SUBMITS TO THE NON-EXCLUSIVE
JURISDICTION OF THE AFORESAID COURTS AND HEREBY WAIVES ANY RIGHTS IT MAY HAVE TO
TRANSFER OR CHANGE THE JURISDICTION OR VENUE OF ANY LITIGATION BROUGHT AGAINST
IT BY THE AGENT, THE COLLATERAL AGENT OR ANY LENDER IN ACCORDANCE WITH THIS
SECTION.

      9.13 Appointment of Agent for Service of Process. Each Borrower hereby
irrevocably designates CT Corporation System, or such other corporate process
agent as is acceptable to the Agent, as the designee, appointee and agent of
such Borrower to receive, for and on behalf of such Borrower, service of process
out of any of the aforementioned courts in any legal action or proceeding with
respect to this Agreement, any other Loan Document or any document related
thereto. It is understood that a copy of such process served on such agent will
be promptly forwarded by mail to such Borrower at its address specified below
its name on the signature pages hereof, but the failure of such Borrower to
receive such copy shall not affect in any way the service of such process. Each
Borrower further irrevocably consents to the service of process of any of the
courts mentioned in Section 9.12 in any such action or proceeding by the mailing
of copies thereof by registered or certified mail, postage prepaid, to such
Borrower at such address, such service to become effective four days after
mailing. Nothing herein shall affect the right of the Agent or any Lender to
serve process in any other manner permitted by law.

      9.14 Waiver of Rights to Jury Trial. THE BORROWERS, THE AGENT, THE
COLLATERAL AGENT, AND EACH LENDER HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY,
IRREVOCABLY, AND UNCONDITIONALLY WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY
ACTION, SUIT, PROCEEDING, COUNTERCLAIM, OR OTHER LITIGATION THAT RELATES TO OR
ARISES OUT OF ANY OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE ACTS OR
OMISSIONS OF THE AGENT, THE COLLATERAL AGENT OR ANY LENDER IN THE ENFORCEMENT OF
ANY OF THE TERMS OR PROVISIONS OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR
OTHERWISE WITH RESPECT THERETO. THE PROVISIONS OF THIS SECTION ARE A MATERIAL
INDUCEMENT FOR THE AGENT, THE COLLATERAL AGENT AND THE LENDERS ENTERING INTO
THIS AGREEMENT.

      9.15 Integration. THIS AGREEMENT AMENDS, RESTATES, AND REPLACES THE
INITIAL AGREEMENT AND CONSTITUTES THE ENTIRE AGREEMENT AMONG THE PARTIES HERETO
WITH


                                       77
<PAGE>   83

RESPECT TO THE SUBJECT HEREOF AND SHALL SUPERSEDE ANY PRIOR AGREEMENT BETWEEN OR
AMONG THE PARTIES, WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT HEREOF.
FURTHERMORE, IN THIS REGARD, THIS AGREEMENT AND THE OTHER WRITTEN LOAN DOCUMENTS
REPRESENT, COLLECTIVELY, THE FINAL AGREEMENT AMONG THE PARTIES THERETO AND MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF SUCH PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG SUCH
PARTIES.

      9.16 Counterparts. For the convenience of the parties, this Agreement may
be executed in multiple counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which together shall constitute one and the same agreement.

      IN WITNESS WHEREOF, this Agreement is executed effective as of the date
first above written.

                          OPINION OF BORROWERS' COUNSEL

                              December _____, 1998

To each Lender party
to the Credit Agreement
referenced below and
Canadian Imperial Bank
of Commerce, as Agent and
CIBC, Inc. as Collateral Agent

      Re: First Amended and Restated Credit Agreement dated as of December
_____, 1998, by and among KCS Resources, Inc., KCS Michigan Resources, Inc., KCS
Energy Marketing, Inc. (collectively, the "Borrowers"), Canadian Imperial Bank
of Commerce, as Agent, CIBC Inc., as Collateral Agent and the lenders party
thereto from time to time (the "Credit Agreement")

Ladies and Gentlemen:

            We have acted as counsel to the Borrowers and KCS Energy, Inc. (the
"Guarantor") in connection with the transactions contemplated in the Credit
Agreement. This Opinion is delivered pursuant to Section 3.1(m) of the Credit
Agreement, and the Agent and the Lenders are hereby authorized to rely upon this
Opinion in connection with the transactions contemplated in the Credit
Agreement. Each capitalized term used but not defined herein shall have the
meaning assigned to such term in the Credit Agreement.

            In our representation of the Borrowers and the Guarantor, we have
examined an executed counterpart of each of the following (the "Loan
Documents"):

            (1) the Credit Agreement;

            (2) the Notes; and

            (3) the Guaranty.

            We have also examined the originals, or copies certified to our
satisfaction, of such other records of the Borrowers and the Guarantor,
certificates of public officials and officers of the Borrowers and the
Guarantor, agreements, instruments, and documents as we have deemed necessary as
a basis for the opinions hereinafter expressed.


                                     VIII-i
<PAGE>   115

            In making such examinations, we have, with your permission, assumed:

            a) the genuineness of all signatures to the Loan Documents other
than those of the Borrowers and the Guarantor;

            b) the authenticity and completeness of all documents submitted to
us as originals and the conformity with the originals of all documents submitted
to us as copies;

            c) the Agent and each Lender is authorized and has the power to
enter into and perform its obligations under the Credit Agreement;

            d) the due authorization, execution, and delivery of all Loan
Documents by each party thereto other than the Borrowers and the Guarantor; and

            e) the representations as to factual matters made by the Borrowers
and the Guarantor in the Loan Documents are true and complete.

            Based upon the foregoing and subject to the qualifications set forth
herein, we are of the opinion that:

            A. Each of the Borrowers and the Guarantor is a corporation duly
organized, legally existing, and in good standing under the laws of its state of
incorporation and is duly qualified as a foreign corporation in the
jurisdictions listed under its name on Schedule A, attached to and made a part
of this Opinion. The execution and delivery by the Borrowers of the respective
Security Instruments to which each Borrower is a party are within the power of
each Borrower and have been duly authorized by all necessary corporate action.

            B. The execution and delivery by the Borrowers of the Credit
Agreement and the borrowings thereunder, the execution and delivery by the
Borrowers of the other Loan Documents to which each Borrower is a party, and the
payment and performance of all obligations of the Borrowers thereunder are
within the power of each Borrower, have been duly authorized by all necessary
corporate action, and do not (a) require the consent of any Governmental
Authority, (b) contravene or conflict with any Requirement of Law or the
articles or certificate of incorporation, bylaws, or other organizational or
governing documents of the Borrowers, (c) to our knowledge, contravene or
conflict with any indenture, instrument, or other agreement to which any
Borrower is a party or by which any Property of any Borrower may be presently
bound or encumbered, or (d) to our knowledge, result in or require the creation
or imposition of any Lien upon any Property of the Borrowers other than as
contemplated by the Loan Documents.

            C. The execution and delivery of the Guaranty and the other Loan
Documents executed by the Guarantor and the performance of all Obligations of
the Guarantor thereunder are within the power of the Guarantor, have been duly
authorized by all necessary corporate action, and do not (a) require the consent
of any Governmental Authority, (b) contravene or conflict with any Requirement
of Law or the articles or certificate of incorporation, bylaws, or other
organizational or governing documents of the Guarantor, (c) to our knowledge,
contravene or conflict with any


                                     VIII-ii
<PAGE>   116

indenture, instrument, or other agreement to which the Guarantor is a party or
by which any Property of the Guarantor may be presently bound or encumbered, or
(d) to our knowledge, result in or require the creation or imposition of any
Lien upon any Property of the Guarantor other than as contemplated by the Loan
Documents.

            D. The Credit Agreement, the Notes and the other Loan Documents
which are governed by New York law to which each Borrower is a party constitute
legal, valid, and binding obligations of such Borrower, enforceable against such
Borrower in accordance with their respective terms.

            E. The Loan Documents to which the Guarantor is a party constitute
legal, valid, and binding obligations of the Guarantor, enforceable against the
Guarantor in accordance with their respective terms.

            F. To our knowledge, except as disclosed in Exhibit X to the Credit
Agreement, no litigation or other action of any nature affecting the Borrowers
or the Guarantor is pending before any Governmental Authority or threatened
against the Borrowers or the Guarantor, which, if determined adversely to such
Borrower or the Guarantor, could reasonably be expected to have a Material
Adverse Effect or affect any Borrower's or the Guarantor's ability to execute,
deliver or perform in any material respect its obligations under the Loan
Documents.

            G. No authorization, consent, approval, exemption, franchise, permit
or license of, or filing (other than filing of Security Instruments in
appropriate filing offices) with, any Governmental Authority or any other Person
is required to authorize or is otherwise required in connection with the valid
execution and delivery by the Borrowers and the Guarantor of those Loan
Documents which are governed by New York Law, or the payment or performance by
the Borrowers and the Guarantor of the Obligations arising pursuant to those
Loan Documents entered into at Closing which are governed by New York law.

            H. No transaction contemplated by the Loan Documents is in violation
of any regulations promulgated by the Board of Governors of the Federal Reserve
System, including, without limitation, Regulations G, T, U, or X.

            I. No Borrower is, nor is any Borrower directly or indirectly
controlled by or acting on behalf of any Person which is, an "investment
company" or an "affiliated person" of an "investment company" within the meaning
of the Investment Company Act of 1940, as amended.

            J. No Borrower is a "holding company," or an "affiliate" of a
"holding company" or of a "subsidiary company" of a "holding company," within
the meaning of the Public Utility Holding Company Act of 1935, as amended.

      The opinions expressed herein are subject to the following qualifications
and limitations:

            We are licensed to practice law only in the States of New Jersey and
New York and other jurisdictions whose laws are not applicable to the opinions
expressed herein; accordingly, the


                                    VIII-iii
<PAGE>   117

foregoing opinions are limited solely to the laws of the State of New Jersey,
the State of New York, applicable United States federal law, and the corporation
laws of the State of Delaware.

            The validity, binding effect, and enforceability of the Loan
Documents or certain provisions thereof may be limited or affected by
bankruptcy, insolvency, moratorium, fraudulent conveyance, reorganization, or
other similar laws affecting rights of creditors generally, including, without
limitation, judicial decisions, statutes or rules of law which limit the effect
of waivers of rights by a debtor or guarantor and limit the permissible scope of
indemnification agreements, provided, however, that the limitations and other
effects of such statutes or rules of law, as currently in effect, upon the
validity and binding effect of the Loan Documents should not differ materially
from the limitations and other effects of such statutes or rules of law upon the
validity and binding effect of credit agreements, promissory notes,
subordination agreements and guaranties generally. No opinion is expressed with
respect to the enforceability of any provisions that may purport to bind the
Borrowers or the Guarantor to the waiver of any right or defense which by virtue
of applicable law or equitable principle cannot be waived.

            The enforceability of the respective obligations of the Borrowers
and the Guarantor under the Loan Documents is subject to general principles of
equity (whether such enforceability is considered in a suit in equity or at
law).

            Whenever our opinion is modified by the phrase "to our knowledge" it
is based solely upon information which we have obtained in the course of our
representation of the Borrowers and the Guarantor in matters to which we have
devoted substantive attention, without any further investigation or inquiry.

            This Opinion is furnished by us solely for the benefit of the Agent
and the Lenders in connection with the transactions contemplated by the Loan
Documents and is not to be quoted in whole or in part or otherwise referred to
or disclosed in any other transaction.

            This Opinion speaks as of the date hereof, and we disclaim any
obligation to update this opinion to you.

            Very truly yours,


            ORLOFF, LOWENBACH, STIFELMAN & SIEGEL, P.A.

Royalty Suits

      The Company is a party to six lawsuits in the Texas State Courts involving
various claims asserted by various holders of royalty interests under leases on
the acreage that was dedicated to the Tennessee Gas Contract or pooled
therewith. One suit involves claims by the holder of an overriding royalty
interest in the dedicated acreage of certain rights in the Tennessee Gas
Contract. Of the other five (the "Royalty Basis Suits"), one seeks a declaratory
judgment on the royalty payment basis for non-dedicated acreage in which the
Company owns no interest. The other four suits seek declaratory judgments to
determine whether royalties payable to the holders of landowner royalty
interests in the dedicated acreage should be based on the net proceeds received
by the Company for gas sales under the Tennessee Gas Contract or on the spot
market price. The Company paid royalties based upon

the spot market price to the holders of royalty interests (other than the
overriding royalty interest) because the Company's leases, which cover only
dedicated acreage, have market value royalty provisions.

      Initially, there were three Royalty Basis Suits, one in Dallas County,
Texas, in which the Company is a co-plaintiff and two subsequently filed suits
in Zapata County, Texas, in which the Company is a co-defendant (the "Las
Blancas Suit" and the "Gonzalez Suit"). The Dallas suit was subsequently split
into four separate lawsuits, based on issues concerning (I) the dedicated
acreage in the Guerra "A" and Guerra "B" Units (the "Los Santos Suit"), (2) the
non-dedicated acreage in those Units (the "Collins Suit"), in which the Company
has no interests, (3) the Jesus Yzaguirre Unit, which consists entirely of
dedicated acreage owned only by the Company (the "Jesus Yzaguirre Suit"), and
(4) the overriding royalty interest in the dedicated acreage (the "Matthews
Suit").

      On March 4,1997, the bolder of an overriding royalty interest filed a
claim against the Company and its co-lessees in the Matthews Suit, alleging
breach of dunes arising from the termination of the Tennessee Gas Contract and
for certain tortious acts. Effective January 23, 1998, the Company and the
royalty holder settled their disputes. On February 3, 1998, the Company and its
co-lessees were dismissed from the Matthews Suit. In addition, in May 1997, the
Gonzalez Suit was dismissed and in October 1997 the Las Blancas Suit was
dismissed.

      The Los Santos Suit and the Jesus Yzaguirre Suit have resulted in separate
summary judgments in favor of the Company's position that royalty payments based
upon the spot market price are all that is required to be paid under the leases
and dismissal of the royalty owners counterclaims and affirmative defenses. In
early 1997, the summary judgment in the Los Santos Suit was appealed to the
Fifth Court of Appeals in Dallas by the royalty holders, who have requested oral
argument on eleven points of error. These points of error concern the granting
of summary judgment against them on issues of lease provisions on market value
royalties; counterclaims and affirmative defenses of fraud, negligent
misrepresentations, conspiracy and estoppel; denial of their efforts to
supplement summary judgment evidence; denial of efforts to transfer venue to
Zapata County; failure to abate the Dallas lawsuit in favor of the two lawsuits
filed by them in Zapata County; and the entry of final judgment in favor of the
Company and its co-plaintiffs.

      In the Jesus Yzaguirre Suit, certain of the royalty owners counterclaimed
against the Company, asserting that the largest lease contained therein had
terminated in December 1975, and that they were entitled to the Tennessee Gas
Contract Price because of the execution of certain division orders in 1992 that
allegedly varied the market value royalty provision of their lease. On May 30,
1997, the Company and these royalty owners reached a settlement of the lease
termination claims, and on June 2, 1997, this issue was dismissed from the Jesus
Yzaguirre Suit. On June 17, 1997, the Company and the royalty owners moved for
summary judgment on the issue of the effect of division orders. The trial judge
granted the Company's motion and denied the competing motion on August 12, 1997.
On October 29, 1997, a final judgment was signed, and on November 19, 1997, the
royalty owners gave notice of their appeal to the Fifth Court of Appeals in
Dallas, Texas. The appellate record has been filed and the royalty owners' brief
was filed with the Fifth Court of Appeals on March 18, 1998. The Company will
file its brief in response to the royalty owners' various points of error and
legal arguments early in the second quarter of 1998.

      Given the inherent uncertainties of appellate matters and notwithstanding
that the Company's position on the market value and other issues is based upon
established decisional law in Texas, the Company is unable to provide any
assurance of a favorable outcome of the appeals from the summary judgments and
evidentiary rulings in the Los Santos Suit and the Jesus Yzaguirre Suit,
inasmuch as the Appellants in each appeal can obtain a reversal and remand for
plenary trial upon showing that summary judgment was improper because there
exists an issue of material fact.

      The aggregate amount at issue in the Los Santos and Jesus Yzaguirre Suits,
apart from certain tort counterclaims and affirmative defenses alleged by the
landowner royalty holders, is a function of the quantity of natural gas for
which Tennessee Gas paid at the contract price. As of January 1, 1997 (the date
of the termination of the Tennessee Gas Contract) the amount of natural gas
taken by Tennessee Gas attributable to the royalty interests involved in the
Royalty Basis Suits was approximately 3.8 Bcf for which royalties have been paid
by the Company at the average price of approximately $1.63 per Mcf, net of
severance tax, compared to the average Tennessee Gas Contract price of
approximately $7.60 per Mcf, net of severance tax. Consequently, if the Company
loses in its litigation with these royalty interest owners on these claims the
Company faces a maximum liability in the Royalty Basis Suits of approximately
$22.7 million, plus interest thereon, at December 31, 1997.

                                    GUARANTY

            2.1 Guaranty. The Guarantor unconditionally guarantees to the Agent
and the Lenders the prompt payment and performance when due (whether at stated
maturity, by acceleration, or otherwise) of the Obligations.

            2.2 Absolute, Complete, and Continuing Guaranty. This is an
absolute, complete, and continuing Guaranty; and no notice of the Obligations,
the making of any Loans, the issuance of any Letter of Credit, the making of any
Letter of Credit Payment, or any extension of credit now or hereafter contracted
by or extended to the Borrowers need be given to the Guarantor. The grant of any
Liens by the Guarantor shall not in anyway limit or be construed as limiting the
Agent or the Collateral Agent to collect payment of any liability of the
Guarantor incurred hereby from the Collateral, but it is expressly understood
and provided that the liability of the Guarantor hereunder shall constitute the
absolute and unconditional obligation of the Guarantor. The Borrowers and the
Lenders may, in accordance with the terms of the Amended and Restated Credit
Agreement, rearrange, extend, increase and/or renew all or any portion of the
Obligations without notice to the Guarantor; and in such event, the Guarantor
shall remain fully bound hereunder for payment of the Guaranteed Indebtedness.
The obligations of the Guarantor hereunder shall not be released, impaired, or
diminished by any amendment, modification, or alteration of any Loan Document,
except as may be expressly provided in any such amendment, modification, or
alteration. The


                                     XIV-iii
<PAGE>   133

Guarantor shall remain liable under this Guaranty regardless of whether the
Borrowers or any other guarantor be found not liable on all or any part of the
Obligations for any reason, including, without limitation, insanity, minority,
disability, bankruptcy, insolvency, death, liquidation, or dissolution, even
though rendering all or any part of the Obligations void, unenforceable, or
uncollectible as against the Borrowers or any other guarantor. This Guaranty
shall continue to be effective or shall be reinstated, as the case may be, if at
any time any payment of any of the Guaranteed Indebtedness is rescinded or must
otherwise be returned by the Agent or any Lender upon the insolvency,
bankruptcy, or reorganization of the Borrowers or otherwise, all as though such
payment had not been made and will, thereupon, guarantee payment of such amount
as to which refund or restitution has been made, together with interest accruing
thereon subsequent to the date of refund or restitution at the applicable rate
under the Amended and Restated Credit Agreement and collection costs and fees
(including, without limitation, reasonable attorneys' fees) applicable thereto.

            2.3 Liability Not Impaired. The liabilities and obligations of the
Guarantor hereunder shall not be affected or impaired by (a) the failure of the
Agent, the Collateral Agent or any other Person to exercise diligence or
reasonable care in the preservation, protection, or other handling or treatment
of all or any part of the Collateral, (b) the failure of any Lien intended to be
granted or created to secure all or any part of the Obligations to be properly
perfected or created or the unenforceability of any Lien for any other reason,
or (c) the subordination of any such Lien to any other Lien.

            2.4 Primary Liability. The liability of the Guarantor for the
payment of the Guaranteed Indebtedness shall be primary and not secondary.

            2.5 Security; Additional Guarantees. The Guarantor authorizes the
Agent and the Lenders, without notice to or demand upon the Guarantor and
without affecting the liability of the Guarantor hereunder, (a) to take and hold
security voluntarily provided by any Person as security for the payment of all
or any portion of the Guaranteed Indebtedness and the other Obligations, and to
exchange, enforce, waive, and/or release any such security; (b) to apply such
security and direct the order or manner of sale thereof as the Agent, the
Collateral Agent or the Lenders in their discretion may determine; and (c) to
obtain a guaranty of all or any portion of the Guaranteed Indebtedness and the
other Obligations from any one or more other Persons and to enforce, waive,
rearrange, modify, limit, or release at any time or times such other Persons
from their obligations under such guaranties, whether with or without
consideration.

            2.6 Waivers. The Guarantor waives any right to require the Agent,
the Collateral Agent or any Lender to (a) proceed against the Borrowers or make
any effort at the collection of the Guaranteed Indebtedness from the Borrowers
or any other guarantor or Person liable for all or any part of the Guaranteed
Indebtedness, (b) proceed against or exhaust any collateral securing the
Guaranteed Indebtedness, or (c) pursue any other remedy in the power of the
Agent, the Collateral Agent or any Lender. The Guarantor further waives any and
all rights and remedies of suretyship. The Guarantor waives any defense arising
by reason of any disability, lack of corporate authority or power, or other
defense of the Borrowers or any other guarantor of all or any part of the
Obligations. The Guarantor expressly waives all notices of any kind, presentment
for payment, demand for payment, protest, notice of protest, notice of intent to
accelerate maturity, notice of


                                     XIV-iv
<PAGE>   134

acceleration of maturity, dishonor, diligence, notice of any amendment of any
Loan Document, notice of any adverse change in the financial condition of the
Borrowers, notice of any adjustment, indulgence, forbearance, or compromise that
might be granted or given by the Agent, the Collateral Agent or any Lender to
the Borrowers, and notice of acceptance of this Guaranty, acceptance on the part
of the Agent being conclusively presumed by its request for this Guaranty and
the delivery of this Guaranty to the Agent. The liability and obligations of the
Guarantor hereunder shall not be affected or impaired by any action or inaction
by the Agent, the Collateral Agent or any Lender in regard to any matter waived
or notice of which is waived by the Guarantor in this Guaranty.

            2.7 Pursuit of Remedies. The Agent, the Collateral Agent and the
Lenders may pursue any remedy without altering the obligations of the Guarantor
hereunder and without liability to the Guarantor, even though the pursuit of
such remedy may result in the loss by the Guarantor of rights of subrogation or
to proceed against others for reimbursement or contribution or any other right.

            2.8 Status of Borrowers. Should the status of the Borrowers change
in any way, as a result of reorganization or dissolution, any sale, lease, or
transfer of any or all of the assets of the Borrowers, any change in the
shareholders, partners, or members of the Borrowers or otherwise, this Guaranty
shall continue and shall cover the Guaranteed Indebtedness under the new status.
This Section shall not, however, be construed to authorize any action by the
Borrowers otherwise prohibited under the Amended and Restated Credit Agreement
or any other Loan Document.

            2.9 Independent Review; Solvency. The Guarantor is familiar with and
has independently reviewed the books and records regarding the financial
condition of the Borrowers and is familiar with the value of any and all
property intended as Collateral; however, the Guarantor is not relying on such
financial condition or such Collateral as an inducement to enter into this
Guaranty. The Guarantor acknowledges that it is not relying on any
representations (oral or otherwise) of the Agent, the Collateral Agent, any
Lender or any other Person except as may be expressly described in this
Guaranty. As of the date hereof, and after giving effect to this Guaranty and
the contingent obligations evidenced hereby, the Guarantor is and will be
solvent, and has and will have Property which, valued fairly, exceed the
obligations, debts, and liabilities of the Guarantor, and has and will have
Property sufficient to satisfy, repay, and discharge the same.

            2.10 Enforcement Costs. If the Guaranteed Indebtedness is not paid
by the Guarantor when due, as required herein, and this Guaranty is placed in
the hands of an attorney for collection or is enforced by suit or through
probate or bankruptcy court or through any other judicial proceedings, the
Guarantor shall pay to the Agent an amount equal to the reasonable attorneys'
fees and collection costs incurred by the Agent, the Collateral Agent or any
Lender in the collection of the Guaranteed Indebtedness.

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

            To induce the Agent, the Collateral Agent and the Lenders to enter
into the Amended and Restated Credit Agreement and to make Loans to or for the
benefit of and to issue Letters of Credit for the account of the Borrowers, the
Guarantor represents and warrants to the Agent (which representations and
warranties shall survive the delivery of this Guaranty and the other Loan
Documents) that:

            3.1 Due Authorization. The execution and delivery by the Guarantor
of this Guaranty and each other Loan Document to which the Guarantor is a party
and the performance of all obligations of the Guarantor hereunder and thereunder
are within the power of the Guarantor, have been duly authorized by all
necessary corporate action, and do not and will not (a) require the consent of
any Governmental Authority to be obtained by the Guarantor, (b) contravene or
conflict with any Requirement of Law applicable to the Guarantor or the articles
or certificate of incorporation, bylaws, or other organizational or governing
documents of the Guarantor, (c) contravene or conflict with any material
indenture, instrument, or other agreement, or any indenture, instrument, or
other agreement that, when aggregated with other such agreements, is material,
to which the Guarantor is a party or by which any Property of the Guarantor may
be presently bound or encumbered, except as could not reasonably be expected to
have a Material Adverse Effect, or (d) result in or require the creation or
imposition of any Lien in, upon or of any Property of the Guarantor under any
such indenture, instrument, or other agreement, other than such Loan Documents.

            3.2 Corporate Existence. The Guarantor is a corporation duly
organized, legally existing, and in good standing under the laws of the State of
Delaware and is duly qualified as a foreign corporation and is in good standing
in all jurisdictions wherein the ownership of Property or the operation of its
business necessitates same, other than those jurisdictions wherein the failure
to so qualify will not have a Material Adverse Effect.

            3.3 Valid and Binding Obligations. This Guaranty and each other Loan
Document to which the Guarantor is a party, when duly executed and delivered by
the Guarantor, will be the legal, valid, and binding obligation of the
Guarantor, enforceable against the Guarantor in accordance with its respective
terms except as limited by bankruptcy, insolvency, or similar laws affecting
generally the rights of creditors and general principles of equity, whether
applied by a court of law or equity.

            3.4 Scope and Accuracy of Financial Statements. The Financial
Statements of the Guarantor and its Subsidiaries as of December 31, 1997 and
September 30, 1998 (subject, in the case of the Financial Statements as of
September 30, 1998, to normal year-end audit adjustments), present fairly the
financial position and results of operations and cash flows of the Guarantor and
its Subsidiaries in accordance with GAAP as at the relevant point in time or for
the period indicated, as applicable. No event or circumstance has occurred since
September 30, 1998, except for the


                                     XIV-vi
<PAGE>   136

material decline of oil and gas prices generally, which could reasonably be
expected to have a Material Adverse Effect.

            3.5 No Material Misstatements. All written estimates, projections
and forecasts furnished by or on behalf of the Guarantor to the Agent, the
Collateral Agent or any of the Lenders for purposes of or in connection with
this Guaranty, or in connection with any extension of credit under the Amended
and Restated Credit Agreement, were and will be prepared on the basis of the
good faith estimate of the Guarantor's senior management concerning probable
financial condition and performance based on assumptions, data, tests or
conditions believed to be reasonable or to represent industry conditions
existing at the time such estimates, projections or forecasts were made. No
other information, exhibit, statement, or report furnished to the Agent, the
Collateral Agent or any Lender by or at the direction of the Guarantor in
connection with this Guaranty or any other Loan Document contains any material
misstatement of fact or omits to state a material fact or any fact necessary to
make the statements contained therein, in light of the circumstances in which
they were made, not misleading as of the date made or deemed made.

            3.6 Litigation. Except as set forth under the heading "Litigation"
on Exhibit X to the Amended and Restated Credit Agreement, no litigation or
other action of any nature is pending before any Governmental Authority or, to
the best knowledge of the Guarantor, threatened, against or affecting (a) any
Collateral, or, in the case of Environmental Laws, any real Property of the
Guarantor or the facilities located and the operations conducted thereon, which,
if determined adversely to the Guarantor, could reasonably be expected to have a
Material Adverse Effect, (b) the Guarantor's ability to enter into, execute,
deliver or perform in any material respect its obligations under the Loan
Documents to which it is a party, (c) the Guarantor, which, if determined
adversely to the Guarantor, could reasonably be expected to result in any
judgment or liability, individually or when aggregated with all other such
judgments or liabilities, which could reasonably be expected to have a Material
Adverse Effect and which is not fully covered by insurance (exclusive of any
deductible amount related to such insurance, which deductible amount is
customary for Persons engaged in similar businesses), or (d) the Guarantor,
which if determined adversely to the Guarantor, could reasonably be expected to
result in any other Material Adverse Effect.

            3.7 Default. Neither any Borrower nor the Guarantor is in default
of, and no event has occurred which, with the lapse of time or giving of notice,
or both, could result in such a default of, (i) any charter document or bylaws
of any Borrower or the Guarantor, or (ii) any agreement or obligation other than
an agreement or obligation evidencing or relating to Debt to which any Borrower
or the Guarantor is a party or by which any Property of any Borrower or the
Guarantor may be bound, pursuant to which the obligations of the Guarantor and
the Borrowers in the aggregate under any of such agreements, or the obligations
secured thereby, exceed $2,500,000, except such as are being contested in good
faith and as to which such reserve as may be required by GAAP shall have been
made therefor.

            3.8 ERISA. No Reportable Event has occurred with respect to any
Single Employer Plan, and each Single Employer Plan has complied with and been
administered in all material respects in accordance with applicable provisions
of ERISA and the Code. To the best knowledge of the Guarantor, (a) no Reportable
Event has occurred with respect to any


                                     XIV-vii
<PAGE>   137

Multiemployer Plan, and (b) each Multiemployer Plan has complied with and been
administered in all material respects with applicable provisions of ERISA and
the Code. Each Plan satisfied the minimum funding requirements under ERISA and
the Code as of the last annual valuation date applicable thereto. Neither the
Guarantor nor any Commonly Controlled Entity has had a complete or partial
withdrawal from any Multiemployer Plan for which there is any withdrawal
liability. As of the most recent valuation date applicable to any Multiemployer
Plan, neither the Guarantor nor any Commonly Controlled Entity would become
subject to any liability under ERISA if the Guarantor or such Commonly
Controlled Entity were to withdraw completely from such Multiemployer Plan.
Neither the Guarantor nor any Commonly Controlled Entity has received notice
that any Multiemployer Plan is Insolvent or in Reorganization. To the best
knowledge of the Guarantor, no such Insolvency or Reorganization which could
reasonably be expected to have a Material Adverse Effect is likely to occur.
Based upon GAAP existing as of the date of this Guaranty and current factual
circumstances, the Guarantor has no reason to believe that the annual cost
during the term of this Guaranty to the Guarantor and all Commonly Controlled
Entities for post-retirement benefits to be provided to the current and former
employees of the Guarantor and all Commonly Controlled Entities under Plans
which are welfare benefit plans (as defined in Section 3(1) of ERISA) will, in
the aggregate, have a Material Adverse Effect.

            3.9 Proper Filing of Tax Returns; Payment of Taxes Due. The
Guarantor has duly and properly filed its United States income tax returns and
all other tax returns which are required to be filed and has paid all taxes
shown to be due thereon, except such as are being contested in good faith and as
to which adequate provisions and disclosures have been made and except such
returns of which the failure to file has not had or would not have a Material
Adverse Effect. The respective charges and reserves on the books of the
Guarantor with respect to taxes and other governmental charges are adequate.

            3.10 Authorizations; Consents. Except as expressly contemplated by
the Loan Documents, no authorization, consent, approval, exemption, franchise,
permit, or license of, or filing with, any Governmental Authority or any other
Person is required to be obtained by the Guarantor to authorize, or is otherwise
required in connection with, the valid execution and delivery by the Guarantor
of this Guaranty or any other Loan Document or the payment and performance by
the Guarantor of the Guaranteed Indebtedness.

            3.11 Compliance with Federal Reserve Regulations. No transaction
contemplated by the Loan Documents is in violation of any regulations
promulgated by the Board of Governors of the Federal Reserve System, including
Regulations G, T, U, or X.

            3.12 Investment Company Act Compliance. The Guarantor is not, nor is
the Guarantor directly or indirectly controlled by or acting on behalf of any
Person which is, an "investment company" or an "affiliated person" of an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

            3.13 Public Utility Holding Company Act Compliance. The Guarantor is
not a "holding company," or an "affiliate" of a "holding company" or of a
"subsidiary company" of a


                                    XIV-viii
<PAGE>   138

"holding company," within the meaning of the Public Utility Holding Company Act
of 1935, as amended.

            3.14 Subsidiaries. As of the Closing Date, the Guarantor has no
Subsidiaries other than those described on Exhibit X to the Amended and Restated
Credit Agreement under the heading "Subsidiaries." The Guarantor is not a
general partner or joint venturer or has partnership or joint venture interests
in any Person.

                                   ARTICLE IV

                              AFFIRMATIVE COVENANTS

            Unless agreed in writing by the Agent to the contrary, the Guarantor
covenants, so long as any Obligation remains outstanding or unpaid or any
Commitments exist, to:

            4.1 Maintenance and Access to Records. Keep adequate records, in
accordance with GAAP, of all its transactions so that at any time, and from time
to time, its true and complete financial condition may be readily determined,
and promptly following the reasonable request of the Agent, the Collateral Agent
or any Lender, make such records available at the Guarantor's place of business
upon reasonable prior notice, during normal business hours, for inspection by
the Agent, the Collateral Agent or any Lender and, at the expense of the
Guarantor, allow the Agent, the Collateral Agent or any Lender to make and take
away copies thereof.

            4.2 Quarterly Financial Statements; Compliance Certificates. Deliver

condition of the Guarantor and its Subsidiaries, subject to changes resulting
from normal year-end audit adjustments, and a Compliance Certificate.

            4.3 Annual Financial Statements. Deliver to the Agent, to the extent
not previously delivered by any Borrower, on or before the 90th day after the

audited consolidated and consolidating Financial Statements of the Guarantor and
its Subsidiaries, and a Compliance Certificate.

            4.4 Projected Budget. Deliver to the Agent as soon as available and

            4.10 Indemnification. Indemnify and hold the Agent, the Collateral
Agent, and each Lender and their respective shareholders, officers, directors,
employees, agents, attorneys-in-fact, and affiliates and each trustee for the
benefit of the Agent, the Collateral Agent, or the Lenders under any Security
Instrument harmless from and against any and all claims, losses, damages,
liabilities, fines, penalties, charges, administrative and judicial proceedings
and orders, judgments, remedial actions, requirements and enforcement actions of
any kind, and all costs and expenses incurred in connection therewith
(including, without limitation, reasonable attorneys' fees and expenses),
arising directly or indirectly, in whole or in part, from (a) the presence of
any Hazardous Substances on, under, or from the Property of the Guarantor or any
Subsidiary, whether prior to or during the term hereof, (b) any activity carried
on or undertaken on or off the Property of the Guarantor or any Subsidiary,
whether prior to or during the term hereof, and whether by the Guarantor or any
Subsidiary or any predecessor in title, employee, agent, contractor, or
subcontractor of the Guarantor or any Subsidiary or any predecessor in title, or
any other Person at any time occupying or present on such Property, in
connection with the handling, treatment, removal, storage, decontamination,
cleanup, transportation, or disposal of any Hazardous Substances at any time
located or present on or under such Property, (c) any residual contamination of
any Hazardous Substance on or under the Property of the Guarantor or any
Subsidiary, (d) any contamination of any Property or natural resources arising
in connection with the generation, use, handling, storage, transportation, or
disposal of any Hazardous Substances by the Guarantor or any Subsidiary or any
employee, agent, contractor, or subcontractor of the Guarantor or any Subsidiary
while such persons are acting within the scope of their relationship with the
Guarantor or any Subsidiary, irrespective of whether any of such activities were
or will be undertaken in accordance with applicable Requirements of Law, or (e)
the performance and enforcement of any Loan Document, any allegation by any
beneficiary of a letter of credit of a wrongful dishonor by the Agent of a claim
or draft presented thereunder, or any other act or omission in connection with
or related to any Loan Document or the transactions contemplated thereby,
including, without limitation, any of the foregoing arising from negligence,
whether sole or concurrent, on the part of the Agent, the Collateral Agent or
any Lender or any of their respective shareholders, officers, directors,
employees, agents, attorneys-in-fact, or affiliates or any trustee for the
benefit of the Agent, the Collateral Agent or the Lenders under any Security
Instrument; provided, however, the foregoing clauses (a) through (e) shall not
apply to any claim, loss, damage, liability, fine, penalty, charge, proceeding,
order, judgment, action or requirement attributable to (i) the gross negligence
or wilful misconduct of any Person to be indemnified, or (ii) any action or
inaction of any Person to be indemnified subsequent to the exercise of ownership
rights or the taking of any foreclosure action with respect to any Collateral
and with respect to such Collateral such claim, loss, damage, liability, fine,
penalty, charge, proceeding, order, judgment, action or requirement arises
subsequent to the exercise of ownership rights or the taking of any foreclosure
action with respect to such Collateral, to the extent such Person is a "person
in control" under any Environmental Law. The foregoing indemnity shall survive
satisfaction of the Guaranteed Indebtedness and all other Obligations and the
termination of this Guaranty and the Amended and Restated Credit Agreement,
unless all Obligations have been satisfied wholly in cash from the Guarantor or
the Borrowers and not by way of realization against any Collateral or the
conveyance of any Property in lieu thereof.

cause to be cured any defects, errors, or omissions in the execution and
delivery of any of the Loan Documents executed by the Guarantor, and execute,

                                    ARTICLE V

                               NEGATIVE COVENANTS

            Unless agreed in writing by the Agent to the contrary, so long as
any Obligation remains outstanding or unpaid or any Commitments exist, the
Guarantor will not:

            5.1 Dividends and Distributions. Declare, pay, or make, whether in
cash or other Property, any dividend or distribution on or purchase, redeem, or
otherwise acquire for value, any share of any class of its capital stock at any
time that (a) an Event of Default exists or will occur as the result of the
payment of such dividend or distribution or (b) such action would result in a
violation of Delaware laws as then in effect; provided, however, the foregoing
restriction shall not apply to dividends paid in or other payments made in
capital stock of the Guarantor or options, warrants or other rights to purchase
such capital stock or to the payment of any dividend within sixty (60) days
after the date of declaration thereof if at such date of declaration such
payment would have complied with the provisions of this Section 5.1; provided
further, so long as the Tranche B Commitments are outstanding, the Guarantor
shall not purchase, redeem or otherwise acquire for value from any Person other
than one of its Subsidiaries any share of any class of its capital stock at any
time, or any of the Public Debt.

            5.2 Changes in Corporate Structure. Enter into any transaction of
consolidation, merger, or amalgamation unless the Guarantor is the surviving
party and no Default will occur due to such transaction; or liquidate, wind up,
or dissolve (or suffer any liquidation or dissolution); or permit any Borrower
to do any of the foregoing in this Section.

            5.3 Transactions with Affiliates. Except as permitted by the Amended
and Restated Credit Agreement, directly or indirectly, enter into any material
transaction (including the sale, lease, or exchange of Property or the rendering
of service) with any of its Affiliates, other than upon fair and reasonable
terms no less favorable than could be obtained in an arm's length transaction
with a Person which was not an Affiliate, or permit any Borrower to do so.

            5.4 Tangible Net Worth. Permit Tangible Net Worth as of September
30, 1998, to be less than $80,000,000 and thereafter at the close of any fiscal
quarter to be less than $80,000,000 plus 50% of positive Net Income and 75% of
the net proceeds from any offering to any Person other than an Affiliate by the
Guarantor or any of its Subsidiaries of capital stock or rights (other than
rights in connection with debt convertible into Equity Securities) to acquire
capital stock in each such quarter.

            5.5 Interest Coverage Ratio. Permit, as of the close of any fiscal
quarter, the ratio of (a) EBITDA for the preceding four fiscal quarters

four fiscal quarters to be less than 2.0 to 1.0.

            5.6 Partnerships and Joint Ventures. Become a general partner, joint
venturer or venturer in any Person or become or assume any similar capacity in
any Person which gives rise to such similar general liability.

            5.7 Lines of Business. Expand, on its own or through any Subsidiary,
into any line of business other than those permitted by the indentures relating
to the Public Debt.

                                   ARTICLE VI

accordance with their terms.

            6.5 No Waiver; Rights Cumulative. No course of dealing on the part
of the Agent, the Collateral Agent or any Lender, their officers or employees,
nor any failure or delay by the Agent, the Collateral Agent or any Lender with
respect to exercising any of its rights under any Loan Document shall operate as
a waiver thereof. The rights of the Agent, the Collateral Agent and the Lenders
under the Loan Documents shall be cumulative and the exercise or partial
exercise of any such right shall not preclude the exercise of any other right.

            6.6 Severability. In the event any one or more of the provisions
contained in any of the Loan Documents shall, for any reason, be held to be
invalid, illegal, or unenforceable in any respect, such invalidity, illegality,
or unenforceability shall not affect any other provision of any Loan Document.

            6.7 Amendments; Waivers. Neither this Guaranty nor any provision

<PAGE>   145

all Lenders, as may be required under the Amended and Restated Credit Agreement
in connection with such amendment or waiver.

            6.8 Review of Guaranty. This Guaranty was reviewed by the Guarantor,
and the Guarantor acknowledges and agrees that it understands fully all of the
terms of this Guaranty and the consequences and implications of its execution of
this Guaranty and has been afforded an opportunity to have this Guaranty
reviewed by an attorney and such other Persons as desired and to discuss the
terms, consequences, and implications of this Guaranty with such attorney and
other Persons.

            6.9 Payments. All amounts becoming payable by the Guarantor under
this Guaranty shall be payable to the Agent at the address of the Agent set
forth hereinabove.

            6.10 Governing Law. This Guaranty shall be deemed to be a contract
made under and shall be construed in accordance with and governed by the laws of
the State of New York without giving effect to principles thereof relating to
conflicts of law.

            6.11 Jurisdiction and Venue. All actions or proceedings with respect
to, arising directly or indirectly in connection with, out of, related to, or
from this Guaranty or any other Loan Document to which the Guarantor is a party
may be litigated, at the sole discretion and election of the Agent, in the
courts of the State of New York or of the United States of America for the
Southern District of New York. The Guarantor hereby submits to the non-exclusive
jurisdiction of the aforesaid courts and hereby waives any rights it may have to
transfer or change the jurisdiction or venue of any litigation brought against
it by the Agent, the Collateral Agent or any Lender in accordance with this
Section.

            6.12 Appointment of Agent for Service of Process. The Guarantor
hereby irrevocably designates CT Corporation System, or such other corporate
process agent as is acceptable to the Agent, as the designee, appointee and
agent of the Guarantor to receive, for and on behalf of the Guarantor, service
of process out of any of the aforementioned courts in any legal action or
proceeding with respect to this Guaranty or any Loan Document to which the
Guarantor is a party. It is understood that a copy of such process served on
such agent will be promptly forwarded by mail to the Guarantor at its address
specified below its name on the signature pages hereof, but the failure of the
Guarantor to receive such copy shall not affect in any way the service of such
process. The Guarantor further irrevocably consents to the service of process of
any of the courts mentioned in Section 6.11 in any such action or proceeding by
the mailing of copies thereof by registered or certified mail, postage prepaid,
to the Guarantor at such address, such service to become effective four days

Collateral Agent or any Lender to serve process in any other manner permitted by
law.

            6.13 Waiver of Rights to Jury Trial. The Guarantor, the Agent, the
Collateral Agent and each Lender hereby knowingly, voluntarily, intentionally,
irrevocably, and unconditionally waive all rights to trial by jury in any
action, suit, proceeding, counterclaim, or other litigation that relates to or
arises out of any of this Guaranty or any other Loan Document or the acts or
omissions of the Agent, the Collateral Agent or any Lender in the

<PAGE>   146

enforcement of any of the terms or provisions of this Guaranty or any other Loan
Document or otherwise with respect thereto. The provisions of this section are a
material inducement for the Agent, the Collateral Agent and the Lenders entering
into the Amended and Restated Credit Agreement.

            6.14 Entire Agreement. The obligations of the Guarantor described
in, arising under and in connection with the prior CIBC Guaranty are hereby
ratified, reaffirmed, renewed and extended, and this Guaranty amends, restates,
and replaces in its entirety the Prior CIBC Guaranty and constitutes the entire
agreement between the parties hereto with respect to the subject hereof and
shall supersede any prior agreements, whether written or oral, between the
parties hereto relating to the subject hereof. Furthermore, in this regard, this
Guaranty and the other written Loan Documents represent, collectively, the final
agreement among the parties thereto and may not be contradicted by evidence of
prior, contemporaneous, or subsequent oral agreements of such parties. There are
no unwritten oral agreements among such parties.

Borrower provides to the Agent, the Collateral Agent, or the Lenders information
belonging to the Guarantor or any Affiliate of the Guarantor, the Agent, the
Collateral Agent, and the Lenders shall thereafter maintain such information in
confidence. This obligation of confidence shall not apply to such portions of

Agent, the Collateral Agent, or the Lenders, (vi) are disclosed with the
Guarantor's consent; (vii) must be disclosed pursuant to any Requirement of Law;

information as is imposed upon it hereunder and such Person agrees to be bound
by the terms hereof. Notwithstanding anything to the contrary provided herein,

                               TERMS OF FACILITIES

      2.1 Tranche A Loans.

            (a) Upon the terms and conditions and relying on the representations
      and warranties contained in this Agreement and the other Loan Documents,
      each Tranche A Lender severally agrees to make Loans (each a "Tranche A
      Loan") during the Tranche A Commitment Period on a revolving basis to or
      for the benefit of the Borrowers, or any combination of them, in an
      aggregate principal amount not to exceed at any time outstanding the
      lesser of the Tranche A Facility Amount of such Lender or the Percentage
      Share of such Lender of the Borrowing Base then in effect (for each
      Lender, its "Tranche A Commitment"); provided, however, that (i) Tranche A
      Obligations shall not exceed at any time the lesser of the Tranche A
      Commitment Amount or the Borrowing Base then in effect, and (ii) the sum
      of the outstanding principal balance of all Tranche A Loans by any Tranche
      A Lender plus the Percentage Share of such Lender of the L/C Exposure
      shall not exceed at any time an amount equal to the Percentage Share of
      such Lender multiplied by the lesser of the Tranche A Commitment Amount or
      the Borrowing Base then in effect. Tranche A Loans shall be made from time
      to time on any Business Day designated by the Borrowers in a Borrowing
      Request.

            (b) Subject to the terms of this Agreement, during the Tranche A
      Commitment Period, the Borrowers may borrow, repay, and reborrow and
      convert Tranche A Loans of one type or with one Interest Period into
      Tranche A Loans of another type or with a different Interest Period.
      Except for prepayments made pursuant to Section 2.13, each borrowing,
      conversion, and prepayment of principal, in the case of Base Rate Loans,
      shall be in an amount at least equal to $100,000 and in multiples of
      $100,000 thereafter and, in the case of LIBO Rate Loans, shall be in an
      amount at least equal to $1,000,000 and in multiples of $100,000
      thereafter. Each borrowing, prepayment, or conversion of or into a Tranche
      A Loan of a different type or, in the case of a LIBO Rate Tranche A Loan,
      having a different Interest Period, shall be deemed a separate borrowing,
      conversion, and prepayment for purposes of the foregoing, one for each
      type of Tranche A Loan or Interest Period. Anything in this Agreement to
      the contrary notwithstanding, the aggregate principal amount of LIBO Rate
      Tranche A Loans having the same Interest Period shall be at least equal to
      $1,000,000; and if any LIBO Rate Loan would otherwise be in a lesser
      principal amount for any period, such Tranche A Loan shall be a Base Rate
      Loan during such period.

            (c) Not later than noon, Eastern Standard or Daylight Savings Time,
      as the case may be, on the date specified for each borrowing of a Tranche
      A Loan, each Tranche A Lender shall make available to the Agent an amount
      equal to the Percentage Share of such Lender of the borrowing to be made
      on such date, at an account designated by the Agent, for the account of
      the Borrowers. The amount so received by the Agent shall, subject to the
      terms and conditions hereof, be made available to the Borrowers in
      immediately available funds by no later than 1:00 p.m. Eastern Standard or
      Daylight Savings Time, as the case may be, in an account designated from
      time to time by the Borrowers. All Tranche A Loans by


                                       22
<PAGE>   28

      each Tranche A Lender shall be maintained at the Applicable Lending Office
      of such Lender and shall be evidenced by the Tranche A Note of such
      Lender.

            (d) The failure of any Tranche A Lender to make any Tranche A Loan
      required to be made by it hereunder shall not relieve any other Tranche A
      Lender of its obligation to make any Tranche A Loan required to be made by
      it, and no Tranche A Lender shall be responsible for the failure of any
      other Tranche A Lender to make any Tranche A Loan.

      2.2 Letter of Credit Facility.

            (a) Upon the terms and conditions and relying on the representations
      and warranties contained in this Agreement, the Agent, as issuing bank for
      the Lenders, agrees, from the date of this Agreement until the date which
      is 30 days prior to the Tranche A Commitment Termination Date, to issue,
      on behalf of the Tranche A Lenders in their respective Percentage Shares,
      Letters of Credit for the account of the Borrowers, or any combination of
      them, and to renew and extend such Letters of Credit. Letters of Credit
      shall be issued, renewed, or extended from time to time on any Business
      Day designated by the Borrowers following the receipt in accordance with
      the terms hereof by the Agent of the written (or oral, confirmed promptly
      in writing) request by a Responsible Officer of each of the Borrowers
      therefor and a Letter of Credit Application. Letters of Credit shall be
      issued in such amounts as the Borrowers may request; provided, however,
      that (i) no Letter of Credit shall have an expiration date which is more
      than 365 days after the issuance thereof or subsequent to one Business Day
      prior to the Tranche A Commitment Termination Date, (ii) Tranche A
      Obligations shall not exceed at any time the lesser of the Tranche A
      Commitment Amount or the Borrowing Base, (iii) the L/C Exposure shall not
      exceed at any time $15,000,000, and (iv) no Letter of Credit shall be
      issued in an amount less than $50,000.

            (b) Prior to any Letter of Credit Payment in respect of any Letter
      of Credit, each Tranche A Lender shall be deemed to be a participant
      through the Agent with respect to the relevant Letter of Credit in the
      obligation of the Agent, as the issuer of such Letter of Credit, in an
      amount equal to the Percentage Share of such Lender of the maximum amount
      which is or at any time may become available to be drawn thereunder. Upon
      delivery by such Lender of funds requested pursuant to Section 2.2(c),
      such Lender shall be treated as having purchased a participating interest
      in an amount equal to such funds delivered by such Lender to the Agent in
      the obligation of the Borrowers to reimburse the Agent, as the issuer of
      such Letter of Credit, for any amounts payable, paid, or incurred by the
      Agent, as the issuer of such Letter of Credit, with respect to such Letter
      of Credit.

            (c) Each Tranche A Lender shall be unconditionally and irrevocably
      liable, without regard to the occurrence of any Default or Event of
      Default, to the extent of the Percentage Share of such Lender at the time
      of issuance of each Letter of Credit, to reimburse, on demand, the Agent,
      as the issuer of such Letter of Credit, for the amount of each Letter of
      Credit Payment under such Letter of Credit. Each Letter of Credit Payment
      shall be deemed to be a Base Rate Tranche A Loan by each Tranche A Lender
      to the extent of funds delivered by such Lender to the Agent with respect
      to such Letter of Credit Payment and shall to such extent be deemed a Base
      Rate Tranche A Loan under and shall be


                                       23
<PAGE>   29

      evidenced by the Tranche A Note of such Lender. In the event that a
      Default has occurred and is continuing under Sections 7.1(f) or (g), an
      amount equal to any Letter of Credit Payment made after the occurrence of
      such Default shall be payable by the Borrowers upon demand by the Agent.
      Notwithstanding anything contained herein or any other Loan Document
      (including any Letter of Credit Application), but subject to the
      provisions of Section 2.13, neither the Agent as the issuing bank nor any
      such Lender shall have any right to require any Borrower to prepay any
      amounts for which the Agent as the issuing bank or any Lender might become
      liable under any Letter of Credit.

            (d) EACH TRANCHE A LENDER AGREES TO INDEMNIFY THE AGENT, AS THE
      ISSUER OF EACH LETTER OF CREDIT, AND THE OFFICERS, DIRECTORS, EMPLOYEES,
      AGENTS, ATTORNEYS-IN-FACT AND AFFILIATES OF THE AGENT (TO THE EXTENT NOT
      REIMBURSED BY THE BORROWERS AND WITHOUT LIMITING THE OBLIGATION OF THE
      BORROWERS TO DO SO), RATABLY ACCORDING TO THE PERCENTAGE SHARE OF SUCH
      LENDER AT THE TIME OF ISSUANCE OF SUCH LETTER OF CREDIT, FROM AND AGAINST
      ANY AND ALL LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES,
      ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND
      WHATSOEVER WHICH MAY AT ANY TIME (INCLUDING ANY TIME FOLLOWING THE PAYMENT
      AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT)
      BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE AGENT AS THE ISSUER OF
      SUCH LETTER OF CREDIT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES,
      AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES IN ANY WAY RELATING TO OR ARISING
      OUT OF THIS AGREEMENT OR SUCH LETTER OF CREDIT OR ANY ACTION TAKEN OR
      OMITTED BY THE AGENT AS THE ISSUER OF SUCH LETTER OF CREDIT OR ANY OF ITS
      OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES
      UNDER OR IN CONNECTION WITH ANY OF THE FOREGOING, INCLUDING ANY
      LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
      JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS IMPOSED, INCURRED OR
      ASSERTED AS A RESULT OF THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE
      AGENT AS THE ISSUER OF SUCH LETTER OF CREDIT OR ANY OF ITS OFFICERS,
      DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES; PROVIDED
      THAT NO TRANCHE A LENDER (OTHER THAN THE AGENT AS THE ISSUER OF A LETTER
      OF CREDIT) SHALL BE LIABLE FOR THE PAYMENT OF ANY PORTION OF SUCH
      LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS,
      SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING SOLELY FROM THE GROSS
      NEGLIGENCE OR WILLFUL MISCONDUCT OF THE AGENT AS THE ISSUER OF A LETTER OF
      CREDIT. THE AGREEMENTS IN THIS SECTION 2.2(d) SHALL SURVIVE THE PAYMENT
      AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT.

      2.3 Tranche B Loans.

            (a) Upon the terms and conditions and relying on the representations
      and warranties contained in this Agreement and the other Loan Documents,
      each Tranche B Lender severally agrees to make Loans (each a "Tranche B
      Loan") during the Tranche B Commitment Period on a revolving basis to or
      for the benefit of the Borrowers, or any combination of them, in an
      aggregate principal amount not to exceed at any time outstanding


                                       24
<PAGE>   30

      the lesser of the Tranche B Facility Amount of such Tranche B Lender or
      the Percentage Share of such Tranche B Lender of the Tranche B Borrowing
      Base then in effect (for each Tranche B Lender, its "Tranche B
      Commitment"); provided, however, that Tranche B Obligations shall not
      exceed at any time the lesser of (y) the Tranche B Commitment Amount or
      (z) the difference between the Tranche B Borrowing Base then in effect
      minus the Borrowing Base then in effect. Tranche B Loans shall be made
      from time to time on any Business Day designated by the Borrowers in a
      Tranche B Borrowing Request but only to the extent such Tranche B Loan
      requested exceeds the Available Tranche A Commitment at such time.

            (b) Subject to the terms of this Agreement, during the Tranche B
      Commitment Period, the Borrowers may borrow, repay, and reborrow and
      convert Tranche B Loans of one type or with one Interest Period into
      Tranche B Loans of another type or with a different Interest Period.
      Except for prepayments made pursuant to Section 2.13, each borrowing,
      conversion, and prepayment of principal, in the case of Base Rate Loans,
      shall be in an amount at least equal to $100,000 and in multiples of
      $100,000 thereafter and, in the case of LIBO Rate Loans, shall be in an
      amount at least equal to $1,000,000 and in multiples of $100,000
      thereafter. Each borrowing, prepayment, or conversion of or into a Tranche
      B Loan of a different type or, in the case of a LIBO Rate Tranche B Loan,
      having a different Interest Period, shall be deemed a separate borrowing,
      conversion, and prepayment for purposes of the foregoing, one for each
      type of Tranche B Loan or Interest Period. Anything in this Agreement to
      the contrary notwithstanding, the aggregate principal amount of LIBO Rate
      Tranche B Loans having the same Interest Period shall be at least equal to
      $1,000,000; and if any LIBO Rate Loan would otherwise be in a lesser
      principal amount for any period, such Tranche B Loan shall be a Base Rate
      Loan during such period.

            (c) Not later than noon, Eastern Standard or Daylight Savings Time,
      as the case may be, on the date specified for each borrowing of a Tranche
      B Loan, each Tranche B Lender shall make available to the Agent an amount
      equal to the Percentage Share of such Tranche B Lender of the borrowing to
      be made on such date, at an account designated by the Agent, for the
      account of the Borrower. The amount so received by the Agent shall,
      subject to the terms and conditions hereof, be made available to the
      Borrowers in immediately available funds by no later than 1:00 p.m.
      Eastern Standard or Daylight Savings Time, as the case may be, in an
      account designated from time to time by the Borrowers. All Tranche B Loans
      by each Tranche B Lender shall be maintained at the Applicable Lending
      Office of such Lender and shall be evidenced by the Tranche B Note of such
      Lender.

            (d) The failure of any Tranche B Lender to make any Tranche B Loan
      required to be made by it hereunder shall not relieve any other Tranche B
      Lender of its obligation to make any Tranche B Loan required to be made by
      it, and no Tranche B Lender shall be responsible for the failure of any
      other Tranche B Lender to make any Tranche B Loan.

            (e) The Borrowers shall have the right at any time and from time to
      time, upon three (3) Business Days' prior and irrevocable written notice
      to the Agent, to terminate or reduce the Tranche B Commitments without
      premium or penalty, in whole or in part, any partial termination to be (i)
      in an amount not less than $1,000,000 as determined by the


                                       25
<PAGE>   31

      Borrowers and in integral multiples of $1,000,000, and (ii) allocated (A)
      either ratably among the Tranche B Lenders in proportion to their
      respective Tranche B Commitments; or (B) in the case of a termination of
      the Tranche B Commitment of a dissenting Tranche B Lender pursuant to
      Section 2.12(h), allocated solely to such Tranche B Lender; provided, that
      the Tranche B Commitment Amounts may not be reduced to an amount less than
      the Tranche B Loan Balance. The Agent shall give prompt notice to each
      Tranche B Lender of any termination or reduction of the Tranche B
      Commitments. Any termination of the Tranche B Commitments pursuant to this
      Section 2.3(e) is permanent and may not be revoked.

      2.4 Limitations on Interest Periods. Each Interest Period selected by the
Borrowers (a) which commences on the last Business Day of a calendar month (or
any day for which there is no numerically corresponding day in the appropriate
subsequent calendar month) shall end on the last Business Day of the appropriate
subsequent calendar month, (b) which would otherwise end on a day which is not a
Business Day shall end on the next succeeding Business Day (or, if such next
succeeding Business Day falls in the next succeeding calendar month, on the next
preceding Business Day), (c) which would otherwise end after Final Maturity
shall end on Final Maturity, and (d) shall have a duration of not less than one
month and, if any Interest Period would otherwise be a shorter period, the
relevant Loan shall be a Base Rate Loan during such period.

      2.5 Limitation on Types of Loans. Borrowings of both Tranche A Loans and
Tranche B Loans may be outstanding respectively as either Base Rate Loans or
LIBO Rate Loans as selected by Borrowers. Anything herein to the contrary
notwithstanding, no more than ten separate Tranche A Loans and five (5) separate
Tranche B Loans shall be outstanding at any one time, with, for purposes of this
Section, all Base Rate Tranche A Loans constituting one Loan, all Base Rate
Tranche B Loans constituting one Loan, all LIBO Rate Tranche A Loans for the
same Interest Period constituting one Loan, and all LIBO Rate Tranche B Loans
for the same Interest Period constituting one Loan. Anything herein to the
contrary notwithstanding, if, on or prior to the determination of any interest
rate for any LIBO Rate Loan for any Interest Period therefor:

            (a) the Agent determines (which determination shall be conclusive,
      absent manifest error) that quotations of interest rates for the deposits
      referred to in the definition of "LIBO Rate" in Section 1.2 are not being
      provided in the relevant amounts or for the relevant maturities for
      purposes of determining the rate of interest for such Loan as provided in
      this Agreement; or

            (b) the Agent or the Required Lenders determine (which determination
      shall be conclusive, absent manifest error) that the rates of interest
      referred to in the definition of "LIBO Rate" in Section 1.2 upon the basis
      of which the rate of interest for such Loan for such Interest Period is to
      be determined do not adequately cover the cost to the Lenders of making or
      maintaining such Loan for such Interest Period,

then the Agent shall give the Borrowers and the Lenders prompt notice thereof;
and so long as such condition remains in effect, the Lenders shall be under no
obligation to make LIBO Rate Loans or to convert Base Rate Loans into LIBO Rate
Loans, and the Borrowers shall, on the last day of the then current Interest
Period for each outstanding LIBO Rate Loan, either prepay such LIBO Rate Loan or
convert such Loan into a Base Rate Loan in accordance with Section 2.14. During
the 30


                                       26
<PAGE>   32

days next succeeding the giving of such notice by the Agent to the Borrowers,
the Borrowers, the Agent and each of the Lenders shall negotiate in good faith
in order to arrive at a mutually satisfactory interest rate for the rates of
interest referred to in the definition "LIBO Rate" or "Adjusted LIBO Rate" for
proposed LIBO Rate Loans. If within such 30-day period the Borrowers, the Agent
and the Lenders shall agree in writing upon a substitute interest rate and the
effective date thereof, such substituted interest rate shall be applicable to
all requests by the Borrowers for proposed LIBO Rate Loans. During any period
when the borrowing of LIBO Rate Loans is suspended or when an alternative
interest rate is in force pursuant to this subsection, the Agent, in
consultation with the Lenders, shall periodically, at least once a month,
determine whether circumstances are such that the interest rates referred to in
the definitions of "LIBO Rate" or "Adjusted LIBO Rate" may again be determined.
If such a determination is made, the Agent shall forthwith give written notice
to the Borrowers and each Lender, whereupon the Agent, the Borrowers and the
Lenders shall begin redetermining the "LIBO Rate" and the "Adjusted LIBO Rate"
in accordance with the terms of the definitions thereof.

      2.6 Use of Loan Proceeds and Letters of Credit.

            (a) Proceeds of all Loans shall be used solely by the Borrowers for
      general corporate purposes, acquisitions and working capital.

            (b) Letters of Credit shall be used solely by the Borrowers for
      general corporate purposes.

      2.7 Interest. Subject to the terms of this Agreement (including Section
2.20), interest on the Loans shall accrue and be payable at a rate per annum
equal to the lesser of (a) the Highest Lawful Rate or (b) the Adjusted Base Rate
for each Base Rate Loan or the Adjusted LIBO Rate for each LIBO Rate Loan.
Notwithstanding the foregoing, interest on past-due principal and, to the extent
permitted by applicable law, past-due interest, shall accrue at the Default Rate
and shall be payable upon demand by the Agent at any time as to all or any
portion of such interest. In the event that the Borrower fails to select the
duration of any Interest Period for any LIBO Rate Loan within the time period
and otherwise as provided herein, such Loan (if outstanding as a LIBO Rate Loan)
will be automatically converted into a Base Rate Loan on the last day of the
then current Interest Period for such Loan or (if outstanding as a Base Rate
Loan) will remain as, or (if not then outstanding) will be made as, a Base Rate
Loan. Interest provided for herein shall be calculated on unpaid sums actually
advanced and outstanding pursuant to the terms of this Agreement and only for
the period from the date or dates of such advances until repayment.

      2.8 Repayment of Loans and Interest. Accrued and unpaid interest on each
outstanding Base Rate Loan shall be due and payable quarterly commencing on the
31st day of December, 1998, and continuing on the last day of each third
calendar month thereafter while any Base Rate Loan remains outstanding, the
payment in each instance to be the amount of interest which has accrued and
remains unpaid in respect of the relevant Loan. Accrued and unpaid interest on
each outstanding LIBO Rate Loan shall be due and payable on the last day of the
Interest Period for such LIBO Rate Loan and, in the case of any Interest Period
in excess of three months, on the day of the third calendar month following the
commencement of such Interest Period corresponding to the day of the calendar
month on which such Interest Period commenced, the payment in each instance to
be


                                       27
<PAGE>   33

the amount of interest which has accrued and remains unpaid in respect of the
relevant Loan. The outstanding principal balance of all Loans, together with all
accrued and unpaid interest thereon, shall be due and payable at Final Maturity.
At the time of making each payment hereunder or under the Notes, the Borrowers
shall specify to the Agent the Loans or other amounts payable by the Borrowers
hereunder to which such payment is to be applied. In the event the Borrowers
fail to so specify, or if an Event of Default has occurred and is continuing,
the Agent shall apply such payment in such manner as the Lenders shall determine
in their sole discretion.

      2.9 General Terms.

            (a) The outstanding principal balance of the Notes of each Lender
      reflected in the records of such Lender shall be deemed rebuttably
      presumptive evidence of the principal amount owing on such Notes. The
      liability for payment of principal and interest evidenced by each such
      Note shall be limited to principal amounts actually advanced and
      outstanding pursuant to this Agreement and interest on such amounts
      calculated in accordance with this Agreement.

            (b) Unless the Agent shall have been notified by a Lender or the
      Borrowers prior to the date on which any of them is scheduled to make
      payment to the Agent of (in the case of a Lender) the proceeds of a Loan
      to be made by such Lender hereunder or (in the case of the Borrowers) a
      payment to the Agent for the account of one or more of the Lenders
      hereunder (such payment, in either case, being herein called the "Required
      Payment"), which notice shall be effective upon receipt, that it does not
      intend to make the Required Payment to the Agent, the Agent may assume
      that the Required Payment has been made and, in reliance upon such
      assumption, may (but shall not be required to) make the amount thereof
      available to the intended recipient on such date. If such Lender or the
      Borrowers, as the case may be, have not in fact made the Required Payment
      to the Agent, the recipient of such payment shall, on demand, repay to the
      Agent for its account the amount so made available together with interest
      thereon in respect of each day during the period commencing on the date
      such amount was so made available by the Agent until the date the Agent
      recovers such amount at a rate per annum equal to, in the case of a Lender
      as recipient, the Federal Funds Rate or, in the case of the Borrowers as
      recipient, the Adjusted Base Rate.

      2.10 Time, Place, and Method of Payments. All payments required pursuant
to this Agreement or the Notes shall be made without set-off or counterclaim in
U.S. Dollars and in immediately available funds. All payments by the Borrowers
shall be deemed received on the next Business Day following receipt if such
receipt is after 3:00 p.m., Eastern Standard or Daylight Savings Time, as the
case may be, on any Business Day, and shall be made to the Agent at the
Principal Office. Except as provided to the contrary herein, if the due date of
any payment hereunder or under any Note would otherwise fall on a day which is
not a Business Day, such date shall be extended to the next succeeding Business
Day, and interest shall be payable for any principal so extended for the period
of such extension.

      2.11 Pro Rata Treatment; Adjustments.

            (a) Except to the extent otherwise expressly provided herein, (i)
      each borrowing of Tranche A Loans pursuant to this Agreement shall be made
      from the Tranche A Lenders pro rata in accordance with their respective
      Percentage Shares, (ii) each payment by the Borrowers of fees payable by
      the Borrowers in respect of Tranche A Loans shall be made for the account
      of the Tranche A Lenders pro rata in accordance with their respective
      Percentage Shares, (iii) each payment of principal of Tranche A Loans
      shall be made for the account of the Tranche A Lenders pro rata in
      accordance with their respective shares of the Tranche A Loan Balance,
      (iv) each payment of interest on Tranche A Loans shall be made for the
      account of the Tranche A Lenders pro rata in accordance with their
      respective Percentage Shares of the aggregate amount of such interest due
      and payable to the Tranche A Lenders, (v) each borrowing of Tranche B
      Loans shall be made from the Tranche B Lenders pro rata in accordance with
      their respective Percentage Shares, (vi) each payment by the Borrowers of
      fees payable by the Borrowers in respect of Tranche B Loans shall be made
      for the account of the Tranche B Lenders pro rata in accordance with their
      respective Percentage Shares, (vii) each payment of principal of Tranche B
      Loans shall be made for the account of the Tranche B Lenders pro rata in
      accordance with their respective shares of the Tranche B Loan Balance, and
      (viii) each payment of interest on Tranche B Loans shall be made for the
      account of the Tranche B Lenders pro rata in accordance with their
      respective Percentage Shares of the aggregate amount of such interest due
      and payable to the Tranche B Lenders.

            (b) The Agent shall distribute all payments with respect to the
      Obligations to the Lenders promptly upon receipt in like funds as
      received. In the event that any payments made hereunder by the Borrowers
      at any particular time are insufficient to satisfy in full the Obligations
      due and payable at such time, such payments shall be applied (i) first, to
      fees and expenses due pursuant to the terms of this Agreement or any other
      Loan Document, (ii) second, to accrued interest, (iii) third, to the Loan
      Balance of the Loans, and (iv) last, to any other Obligations.

            (c) If any Tranche A Lender (for purposes of this Section, a
      "Benefitted Tranche A Lender") shall at any time receive any payment of
      all or part of its portion of the Obligations, or receive any Collateral
      in respect thereof (whether voluntarily or involuntarily, by set-off,
      pursuant to events or proceedings of the nature referred to in Sections
      7.1(f) or 7.1(g), or otherwise) in an amount greater than such Lender was
      entitled to receive pursuant to the terms hereof, such Benefitted Tranche
      A Lender shall purchase for cash from the other Tranche A Lenders such
      portion of the Obligations of such other Lenders, or shall provide such
      other Tranche A Lenders with the benefits of any such Collateral or the
      proceeds thereof, as shall be necessary to cause such Benefitted Tranche A
      Lender to share the excess payment or benefits of such Collateral or
      proceeds with each of the Tranche A Lenders according to the terms hereof.
      If all or any portion of such excess payment or benefits is thereafter
      recovered from such Benefitted Tranche A Lender, such purchase shall be
      rescinded and the purchase price and benefits returned by such Lender, to
      the extent of such recovery, but without interest. The Borrower agrees
      that each such Lender so purchasing a portion of the Obligations of
      another Lender may exercise all rights of payment (including rights of
      set-off) with respect to such portion as fully as if such Lender were the
      direct holder


                                       29
<PAGE>   35

      of such portion. If any Tranche A Lender ever receives, by voluntary
      payment, exercise of rights of set-off or banker's lien, counterclaim,
      cross-action or otherwise, any funds of the Borrower to be applied to the
      Obligations, or receives any proceeds by realization on or with respect to
      any Collateral, all such funds and proceeds shall be forwarded immediately
      to the Agent for distribution in accordance with the terms of this
      Agreement.

            (d) If any Tranche B Lender (for purposes of this Section, a
      "Benefitted Tranche B Lender") shall at any time receive any payment of
      all or part of its portion of the Obligations, or receive any Collateral
      in respect thereof (whether voluntarily or involuntarily, by set-off,
      pursuant to events or proceedings of the nature referred to in Sections
      7.1(f) or 7.1(g), or otherwise) in an amount greater than such Lender was
      entitled to receive pursuant to the terms hereof, such Benefitted Tranche
      B Lender shall purchase for cash from the other Tranche B Lenders such
      portion of the Obligations of such other Lenders, or shall provide such
      other Tranche B Lenders with the benefits of any such Collateral or the
      proceeds thereof, as shall be necessary to cause such Benefitted Tranche B
      Lender to share the excess payment or benefits of such Collateral or
      proceeds with each of the Tranche B Lenders according to the terms hereof.
      If all or any portion of such excess payment or benefits is thereafter
      recovered from such Benefitted Tranche B Lender, such purchase shall be
      rescinded and the purchase price and benefits returned by such Lender, to
      the extent of such recovery, but without interest. The Borrower agrees
      that each such Lender so purchasing a portion of the Obligations of
      another Lender may exercise all rights of payment (including rights of
      set-off) with respect to such portion as fully as if such Lender were the
      direct holder of such portion. If any Tranche B Lender ever receives, by
      voluntary payment, exercise of rights of set-off or banker's lien,
      counterclaim, cross-action or otherwise, any funds of the Borrower to be
      applied to the Obligations, or receives any proceeds by realization on or
      with respect to any Collateral, all such funds and proceeds shall be
      forwarded immediately to the Agent for distribution in accordance with the
      terms of this Agreement.

            (e) Notwithstanding any of the provisions of this Section 2.11,
      after the occurrence and during the continuance of an Event of Default,
      the Lenders may apply payments in respect of the Obligations in such
      manner as the Lenders shall determine in their sole discretion.

      2.12 Borrowing Base and Tranche B Borrowing Base Determinations.

            (a) The Borrowing Base as of the Closing Date is agreed by the
      Borrowers and the Tranche A Lenders to be $80,000,000.

            (b) The Borrowing Base shall be redetermined by the Agent, with the
      consent of the Tranche A Lenders, semi-annually on the basis of
      information supplied by the Borrowers in compliance with the provisions of
      this Agreement, including Reserve Reports, and all other information
      available to the Agent and the Lenders. In addition, the Agent, with the
      consent of the Tranche A Lenders, shall, in the normal course of business
      following a request of the Borrowers, redetermine the Borrowing Base;
      provided, however, the Agent and the Tranche A Lenders shall not be
      obligated to respond to more than two (2) such requests during any
      calendar year in addition to each scheduled semi-annual redetermination
      provided


                                       30
<PAGE>   36

      for above. Notwithstanding the foregoing, the Agent, with the consent of
      the Tranche A Lenders, may at its discretion redetermine the Borrowing
      Base at any time and from time to time.

            (c) Each determination of the Borrowing Base shall be made within
      forty-five (45) days of the Agent's receiving all of the information
      required under this Agreement in connection therewith. Upon each
      determination of the Borrowing Base, the Agent shall promptly, and in all
      events within such 45 days, notify the Borrowers orally (confirming such
      notice promptly in writing) of such determination and the Borrowing Base
      so communicated to the Borrowers shall become effective upon such oral
      notification and shall remain in effect until the next subsequent
      determination of the Borrowing Base.

            (d) In connection with any redetermination of the Borrowing Base,
      the Agent and each Tranche A Lender shall evaluate the Mortgaged
      Properties in accordance with their then existing customary lending
      procedures for evaluating oil and gas reserves and related assets for
      loans of this type and borrowers similarly situated. The Borrowing Base
      shall represent the determination by the Agent based upon such evaluation
      by the Agent, with the consent of the Tranche A Lenders, of the value for
      loan purposes of the Mortgaged Properties, subject, in the case of any
      increase in the Borrowing Base, to the credit approval processes of the
      Tranche A Lenders then in effect for loans of this type and borrowers
      similarly situated. Except as hereinafter provided, in the event that a
      group of Tranche A Lenders constituting at least the Tranche A Required
      Lenders are in agreement as to the amount of any Borrowing Base
      redetermination but such amount is not approved unanimously by all of the
      Tranche A Lenders, then the Borrowing Base shall be the amount as
      determined by such Tranche A Required Lenders for a period of 60 days from
      the date of notification of such Borrowing Base to the Borrowers pursuant
      to Section 2.12(c). Notwithstanding the foregoing provisions of this
      Section 2.12(d), if at any time the Borrowing Base redetermination by the
      Agent results in an increase in the Borrowing Base and such Borrowing Base
      is not approved unanimously by all the Tranche A Lenders, then, in such
      event, the Borrowing Base shall, during the sixty (60) day period from the
      date of notification of the Borrowing Base to the Borrowers pursuant to
      Section 2.12(c), be the amount agreed to by the Agent and all of the
      Tranche A Lenders, but in any event not less than the amount which existed
      immediately prior to such redetermination by the Agent. During such 60 day
      period or at any time thereafter, the Borrowers may, at their election,
      terminate the Commitments of such dissenting Tranche A Lenders pursuant to
      the procedures set forth in Section 2.25. At the end of such 60 day
      period, the Borrowing Base shall be an amount agreed to by the Agent and
      all of the Tranche A Lenders. Furthermore, subject to the customary
      lending procedures and credit approval processes referred to in the
      preceding sentence, each Borrower acknowledges that the Agent and the
      Lenders have no obligation to increase the Borrowing Base and may reduce
      the Borrowing Base, in either case, at any time or as a result of any
      circumstance, and further acknowledges that the determination of the
      Borrowing Base contains an equity cushion (market value in excess of loan
      value), which is acknowledged by each Borrower to be essential for the
      adequate protection of the Tranche A Lenders.


                                       31
<PAGE>   37

            (e) The Tranche B Borrowing Base (the "Tranche B Borrowing Base") is
      agreed by the Borrowers and the Tranche B Lenders to be (i) $90,000,000
      from the Closing Date through the later of (y) March 31, 1999 and (z) the
      date of the next determination of the Tranche B Borrowing Base in
      accordance with Sections 2.12(f), (g) and (h), and (ii) thereafter, such
      amount as shall be determined by the Tranche B Lenders in the manner
      provided in Section 2.12(f), (g) and (h) of this Agreement.

            (f) The Tranche B Borrowing Base shall be redetermined by the Agent,
      with the consent of the Tranche B Lenders, semi-annually commencing March
      31, 1999 on the basis of information supplied by the Borrowers in
      compliance with the provisions of this Agreement, including Reserve
      Reports, and all other information available to the Agent and the Lenders.
      In addition, the Agent, with the consent of the Tranche B Lenders, with
      the assistance of the Agent, shall, in the normal course of business
      following a request of the Borrowers, redetermine the Borrowing Base;
      provided, however, the Agent and the Tranche B Lenders shall not be
      obligated to respond to more than two (2) such requests during any
      calendar year in addition to each scheduled semi-annual redetermination
      provided for above. Notwithstanding the foregoing, the Agent, with the
      consent of the Tranche B Lenders, may (except as provided in Section
      2.12(e)(i)) at its discretion redetermine the Tranche B Borrowing Base at
      any time and from time to time.

            (g) Each determination of the Tranche B Borrowing Base shall be made
      within forty-five (45) days of the Agent's receiving all of the
      information required under this Agreement in connection therewith. Upon
      each determination of the Tranche B Borrowing Base, the Agent shall
      promptly, and in all events within such 45 days, notify the Borrowers
      orally (confirming such notice promptly in writing) of such determination
      and the Tranche B Borrowing Base so communicated to the Borrowers shall
      become effective upon such oral notification and shall remain in effect
      until the next subsequent determination of the Tranche B Borrowing Base.

            (h) In connection with any redetermination of the Tranche B
      Borrowing Base, the Agent and each Tranche B Lender shall evaluate the
      Mortgaged Properties in accordance with their then existing customary
      lending procedures for evaluating oil and gas reserves and related assets
      for loans of this type and borrowers similarly situated. The Tranche B
      Borrowing Base shall represent the determination by the Agent based upon
      such evaluation by the Agent, with the consent of the Tranche B Lenders,
      of the value for loan purposes of the Mortgaged Properties, subject, in
      the case of any increase in the Tranche B Borrowing Base, to the credit
      approval processes of the Tranche B Lenders then in effect for loans of
      this type and borrowers similarly situated. In the event that a group of
      Tranche B Lenders constituting at least the Tranche B Required Lenders are
      in agreement as to the amount of any Tranche B Borrowing Base
      redetermination but such amount is not approved unanimously by all of the
      Tranche B Lenders, then the Tranche B Borrowing Base shall be the amount
      as determined by such Tranche B Required Lenders for a period of 60 days
      from the date of notification of such Tranche B Borrowing Base to the
      Borrowers pursuant to Section 2.12(g). During such 60 day period or at any
      time thereafter, the Borrowers may, at their election, (x) terminate the
      Tranche B Commitment of such dissenting Tranche B Lender(s) in accordance
      with Section 2.3(e), or (y) substitute a new Tranche B Lender or


                                       32
<PAGE>   38

      Lenders for such dissenting Lender(s) pursuant to the procedures set forth
      in Section 2.25. At the end of such 60 day period, the Tranche B Borrowing
      Base shall be an amount agreed to by the Agent and all of the Tranche B
      Lenders. Furthermore, subject to the customary lending procedures and
      credit approval processes referred to in the preceding sentence, each
      Borrower acknowledges that the Agent and the Tranche B Lenders have no
      obligation to increase the Tranche B Borrowing Base and may, subject to
      Section 2.12(e)(i), reduce the Tranche B Borrowing Base, in either case,
      at any time or as a result of any circumstance, and further acknowledges
      that the determination of the Tranche B Borrowing Base contains an equity
      cushion (market value in excess of loan value), which is acknowledged by
      each Borrower to be essential for the adequate protection of the Tranche B
      Lenders.

      2.13 Mandatory Prepayments.

            (a) If at any time the Tranche A Obligations exceed the lesser of
      the Tranche A Commitment Amount or the Borrowing Base then in effect, the
      Borrowers shall, within 30 days of notice from the Agent of such
      occurrence, (i) prepay, or make arrangements acceptable to the Tranche A
      Required Lenders for the prepayment of, the amount of such excess for
      application on the Loan Balance of the Tranche A Loans, (ii) provide
      additional collateral, of character and value satisfactory to the Tranche
      A Required Lenders in their sole discretion, to secure the Obligations by
      the execution and delivery to the Agent of security instruments in form
      and substance satisfactory to the Agent, or (iii) effect any combination
      of the alternatives described in clauses (i) and (ii) of this Section
      2.13(a) and acceptable to the Tranche A Required Lenders in their
      discretion. In the event that a mandatory prepayment is required under
      this Section 2.13(a) and the Tranche A Loan Balance is less than the
      amount required to be prepaid, the Borrowers shall repay the entire
      Tranche A Loan Balance together with accrued interest, and, in accordance
      with the provisions of the relevant Letter of Credit Applications executed
      by the Borrowers or otherwise to the satisfaction of the Agent, deposit
      with the Agent, as additional collateral securing the Obligations, an
      amount of cash, in immediately available funds, equal to the L/C Exposure
      minus the lesser of the Tranche A Commitment Amount or the Borrowing Base.
      The cash deposited with the Agent in satisfaction of the requirement
      provided in this Section 2.13 may be invested at the express direction of
      the Borrowers as to investment vehicle and maturity (which shall be no
      later than the latest expiry date of any then outstanding Letter of
      Credit), for the account of the Borrowers in cash or cash equivalent
      investments offered by or through the Agent.

            (b) For so long as any Tranche B Commitment is outstanding, in the
      event after the Closing Date any Borrower (i) issues or incurs
      Subordinated Indebtedness or Public Debt to any Person other than an
      Affiliate or (ii) issues, transfers, sells, assigns, or conveys to any
      Person other than an Affiliate (an "Equity Sale") (y) all or any portion
      of the capital stock of any other Borrower, or (z) any equity interest in
      itself or any other Borrower, then, in any such event, an amount equal to
      fifty percent (50%) of the Net Cash Proceeds from the issuance or
      incurrence of such Subordinated Indebtedness up to the then outstanding
      principal amount of the Tranche B Loans, if any, and fifty percent (50%)
      of the Net Cash Proceeds from the issuance, sale, assignment or conveyance
      of such Equity Sale up to the then outstanding principal amount of the
      Tranche B Loans, if any, shall be applied for reduction of the Tranche B
      Loans in the manner determined by the Lenders, and the Tranche


                                       33
<PAGE>   39

      B Commitments then in effect (if any) shall be irrevocably reduced prorata
      to the extent of fifty percent (50%) of the Net Cash Proceeds from the
      issuance or incurrence of such Subordinated indebtedness or Public Debt
      and fifty percent (50%) of the Net Cash Proceeds from the issuance, sale,
      assignment or conveyance of such Equity Sale.

            (c) If at any time the Tranche B Obligations exceed the lesser of
      (i) the Tranche B Commitment Amount or (ii) the difference between the
      Tranche B Borrowing Base then in effect minus the Borrowing Base then in
      effect, the Borrowers shall, within 30 days of notice from the Agent of
      such occurrence, (i) prepay, or make arrangements acceptable to the
      Tranche B Required Lenders for the prepayment of, the amount of such
      excess for application on the Tranche B Loan Balance, (ii) provide
      additional collateral, of character and value satisfactory to the Tranche
      B Required Lenders in their sole discretion, to secure the Obligations by
      the execution and delivery to the Agent of security instruments in form
      and substance satisfactory to the Agent, or (iii) effect any combination
      of the alternatives described in clauses (i) and (ii) of this Section
      2.13(c) and acceptable to the Tranche B Required Lenders in their
      discretion. If at any time, Tranche B Obligations are outstanding when
      Available Tranche A Commitment exists, the Borrowers shall, (i) in the
      case of such Tranche B Obligations which are Base Rate Tranche B Loans, to
      the extent of the Available Tranche A Commitment, prepay such Loans within
      three Business Days of the occurrence of such condition, or (ii) in the
      case of such Tranche B Obligations which are LIBO Rate Tranche B Loans, to
      the extent of the Available Tranche A Commitment, on the last day of the
      Interest Period to which such Loans are subject, prepay such Loans on the
      last day of the Interest Period to which such Loans are subject. In the
      event that a mandatory prepayment is required under this Section 2.13(c)
      and the Tranche B Loan Balance is less than the amount required to be
      prepaid, the Borrowers shall repay the entire Loan Balance of the Tranche
      B Loans.

      2.14 Voluntary Prepayments and Conversions of Loans. Subject to applicable
provisions of this Agreement, the Borrowers shall have the right at any time or
from time to time to prepay Loans and to convert Loans of one type or with one
Interest Period into Loans of another type or with a different Interest Period;
provided, however, that (a) the Borrowers shall give the Agent notice of each
such conversion of all or any portion of a LIBO Rate Loan no less than three
Business Days prior to conversion, (b) any LIBO Rate Loan may be prepaid or
converted only on the last day of an Interest Period for such Loan, unless the
Borrowers pay, within the time period set forth therefor in Section 2.22(e), the
amount, if any, required to be paid under Section 2.22(e), (c) each prepayment,
in the case of Base Rate Loans, shall be in an amount not less than $100,000 or
incremental amounts of $100,000 in excess thereof or the Loan Balance of such
Loans and, in the case of LIBO Rate Loans, shall be in an amount not less than
$1,000,000 or incremental amounts of $100,000 in excess thereof or the Loan
Balance of such Loans, (d) the Borrower shall pay all accrued and unpaid
interest on the amounts prepaid or converted, and (e) no such prepayment or
conversion shall serve to postpone the repayment when due of any Obligation.

      2.15 Commitment Fees and Usage Fee.

            (a) To compensate the Tranche A Lenders for maintaining funds
      available under the Tranche A Commitment, the Borrowers shall pay to the
      Agent for the account of such


                                       34
<PAGE>   40

      Lenders a fee equal to (i) at all times the Tranche B Commitments are
      outstanding and existing, one-half of one percent (0.50%) per annum times
      the average daily amount of the Available Tranche A Commitment during the
      immediately preceding fiscal quarter just ended (or shorter period thereof
      in the case of the fee for the period from the date of this Agreement and
      ending December 31, 1998 or the period ending on the Tranche A Commitment
      Termination Date) or (ii) in the event the Tranche B Commitments are
      irrevocably terminated, (y) in the event the average daily amount of the
      Available Tranche A Commitment during the immediately preceding fiscal
      quarter just ended (or shorter period thereof in the case of the fee for
      the period from the date of this Agreement and ending December 31, 1998 or
      the period ending on the Tranche A Commitment Termination Date) is equal
      to or more than sixty-six and two-thirds percent (66 2/3%) of the average
      daily amount of the Tranche A Commitments during such immediately
      preceding fiscal quarter (or any such shorter period), thirty-seven and
      one-half one hundredths of one percent (0.375%) per annum times the
      average daily amount of the Available Tranche A Commitment for such
      quarter or shorter period, or (z) in the event the average daily amount of
      the Available Tranche A Commitment during the immediately preceding fiscal
      quarter just ended (or shorter period thereof in the case of the fee for
      the period from the date of this Agreement and ending December 31, 1998 or
      the period ending on the Tranche A Commitment Termination Date) is less
      than sixty-six and two thirds percent (66 2/3%) of the average daily
      amount of the Tranche A Commitments during such immediately preceding
      fiscal quarter (or any such shorter period), one half of one percent
      (0.50%) per annum times the average daily amount of the Available Tranche
      A Commitment for such quarter or shorter period, in each case calculated
      on the basis of a year of 365 or 366 days, as the case may be, and actual
      days elapsed (including the first day but excluding the last day); such
      accrued commitment fees shall be payable in arrears on the 31st day of
      December, 1998, the last day of each third calendar month thereafter
      during the Tranche A Commitment Period, and on the Tranche A Commitment
      Termination Date;

            (b) To compensate the Tranche B Lenders for maintaining funds
      available under the Tranche B Commitment the Borrowers shall pay to the
      Agent for the account of such Tranche B Lenders, a fee equal to one-half
      of one percent (0.50%) per annum, times the average daily amount of the
      Available Tranche B Commitment during the immediately preceding fiscal
      quarter just ended (or shorter period thereof in the case of the fee for
      the period from the date of this Agreement and ending December 31, 1998 or
      the period ending on the Tranche B Commitment Termination Date),
      calculated on the basis of a year of 365 or 366 days, as the case may be,
      and actual days elapsed (including the first day but excluding the last
      day); such accrued commitment fees shall be payable in arrears on the 31st
      day of December, 1998, the last day of each third calendar month
      thereafter during the Tranche B Commitment Period, and on the Tranche B
      Commitment Termination Date; and

            (c) To compensate the Tranche B Lenders for advancing Tranche B
      Loans, subject to the provisions of Section 2.20, on the date of any
      borrowing of a Tranche B Loan where, after giving effect to such Loan, the
      aggregate principal amount of Tranche B Loans then outstanding exceeds the
      maximum aggregate principal amount of Tranche B Loans theretofore
      outstanding at any one time (the amount of such excess on any such
      borrowing date, herein called an "Excess Amount"), the Borrowers shall pay
      to the Agent, for the


                                       35
<PAGE>   41

      account of the Tranche B Lenders, a fee ("Usage Fee") equal to
      one-and-one-fourth percent (1.25%) times such Excess Amount on such date
      of borrowing.

      2.16 Letter of Credit Fee. The Borrowers shall pay to the Agent for the
account of the Tranche A Lenders a letter of credit fee in the amount of the
Applicable Margin for LIBO Rate Loans in effect at such time per annum,
calculated on the basis of a year of 360 days and actual days elapsed (including
the first day but excluding the last day), on the average daily amount of the
L/C Exposure. Accrued letter of credit fees shall be payable quarterly in
arrears on the 31st day of December, 1998, the last day of each third calendar
month thereafter during the Tranche A Commitment Period, and at Final Maturity
of the Tranche A Loans. The Borrower shall pay to the Agent for its own account
as the issuer of each Letter of Credit, on the date of issuance or renewal of
each Letter of Credit, an issuing fee equal to one-eighth of one percent (.125%)
per annum, calculated on the basis of a year of 365 or 366 days, as the case may
be, and actual days elapsed (including the first day but excluding the last
day), on the face amount of such Letter of Credit during the period for which
such Letter of Credit is issued or renewed. The Borrowers also agree to pay on
demand to the Agent for its own account as the issuer of the Letters of Credit
its customary letter of credit transactional fees and expenses, including
amendment fees, payable with respect to each Letter of Credit.

      2.17 Other Fees. The Borrowers shall pay to the Agent on the Closing Date
(a) for the account of the Tranche A Lenders an amendment fee (the "Tranche A
Amendment Fee") equal to $100,000 representing one-eighth of one percent
(0.125%) of the aggregate of the Tranche A Commitments and (b) for the account
of the Tranche B Lenders, a commitment fee (the "Tranche B Commitment Fee")
equal to $125,000 representing one and one-fourth percent (1.25%) of the
aggregate of the Tranche B Commitments.

      2.18 Loans to Satisfy Obligations of Borrowers. The Lenders may, with the
consent of the Agent, but shall not be obligated to, make Loans for the benefit
of the Borrowers and apply proceeds thereof to the satisfaction of any
condition, warranty, representation, or covenant of the Borrowers contained in
this Agreement or any other Loan Document. Such Loans shall be evidenced by the
Notes, shall bear interest at the Default Rate, and shall be payable upon
demand.

      2.19 Right of Offset. The Borrowers hereby grant to the Agent and each
Lender (for the benefit of all Lenders) the right, exercisable at such time as
any Event of Default shall occur, of offset or banker's lien against all funds
of the Borrowers now or hereafter or from time to time on deposit with the Agent
or such Lender, regardless of whether the exercise of any such remedy would
result in any penalty or loss of interest or profit with respect to any
withdrawal of funds deposited in a time deposit account prior to the maturity
thereof.

      2.20 General Provisions Relating to Interest.

            (a) It is the intention of the parties hereto to comply strictly
      with all applicable usury laws. In this connection, there shall never be
      collected, charged, or received on the sums advanced hereunder interest in
      excess of that which would accrue at the Highest Lawful Rate.


                                       36
<PAGE>   42

            (b) Notwithstanding anything herein or in the Notes to the contrary,
      during any Limitation Period, the interest rate to be charged on amounts
      evidenced by the Notes shall be the Highest Lawful Rate, and the
      obligation, if any, of each Borrower for the payment of fees or other
      charges deemed to be interest under applicable law shall be suspended.
      During any period or periods of time following a Limitation Period, to the
      extent permitted by applicable law, the interest rate to be charged
      hereunder shall remain at the Highest Lawful Rate until such time as there
      has been paid to the Agent and each Lender (i) the amount of interest in
      excess of that accruing at the Highest Lawful Rate that such Lender would
      have received during the Limitation Period had the interest rate remained
      at the otherwise applicable rate, and (ii) all interest and fees otherwise
      payable to the Agent and such Lender but for the effect of such Limitation
      Period.

            (c) If, under any circumstances, the aggregate amounts paid on the
      Notes or under this Agreement or any other Loan Document include amounts
      which by applicable law are deemed interest and which would exceed the
      amount permitted if the Highest Lawful Rate were in effect, each Borrower
      stipulates that such payment and collection will have been and will be
      deemed to have been, to the extent permitted by applicable law, the result
      of mathematical error on the part of such Borrower, the Agent, and the
      Lenders; and the party receiving such excess shall promptly refund the
      amount of such excess (to the extent only of such interest payments in
      excess of that which would have accrued and been payable on the basis of
      the Highest Lawful Rate) upon discovery of such error by such party or
      notice thereof from such Borrower. In the event that the maturity of any
      Obligation is accelerated, by reason of an election by the Lenders or
      otherwise, or in the event of any required or permitted prepayment, then
      the consideration constituting interest under applicable law may never
      exceed the Highest Lawful Rate, and excess amounts paid which by
      applicable law are deemed interest, if any, shall be credited by the Agent
      and the Lenders on the principal amount of the Obligations, or if the
      principal amount of the Obligations shall have been paid in full, refunded
      to such Borrower.

            (d) All sums paid, or agreed to be paid, to the Agent and the
      Lenders for the use, forbearance and detention of the proceeds of any
      advance hereunder shall, to the extent permitted by applicable law, be
      amortized, prorated, allocated, and spread throughout the full term hereof
      until paid in full so that the actual rate of interest is uniform but does
      not exceed the Highest Lawful Rate throughout the full term hereof.

      2.21 Obligations Absolute. Subject to the further provisions of this
Section, the Obligations of the Borrowers under this Article shall be absolute
and unconditional under any and all circumstances and irrespective of any
set-off, counterclaim, or defense to payment or performance which the Borrowers
may have or have had against the Agent, any Lender, or any beneficiary of any
Letter of Credit. Each Borrower agrees that none of the Agent or the Lenders
shall be responsible for, nor shall the Obligations be affected by, among other
things, (a) the validity or genuineness of documents or any endorsements thereon
presented in connection with any Letter of Credit, even if such documents shall
in fact prove to be in any and all respects invalid, fraudulent or forged, AND
EVEN IF DUE TO THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT OR ANY
LENDER, so long as the Agent, as the issuer of such Letter of Credit, has no
actual knowledge of any such invalidity, lack of genuineness, fraud, or forgery
prior to the presentment for payment of a


                                       37
<PAGE>   43

corresponding Letter of Credit or any draft thereunder, or (b) any dispute
between or among the Borrowers and any beneficiary of any Letter of Credit or
any other party to which any Letter of Credit may be transferred, or any claims
whatsoever of the Borrowers against any beneficiary of any Letter of Credit or
any such transferee, EVEN IF DUE TO THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT,
OF THE AGENT OR ANY LENDER; provided, in all respects, that the Agent, as the
issuer of Letters of Credit, shall be liable to the Borrowers to the extent, but
only to the extent, of any damages (other than punitive damages) suffered by the
Borrowers as a result of the willful misconduct or gross negligence of the Agent
as the issuer of Letters of Credit in determining whether documents presented
under a Letter of Credit complied with the terms of such Letter of Credit that
resulted in either a wrongful payment under such Letter of Credit or a wrongful
dishonor of a claim or draft properly presented under such Letter of Credit. In
the absence of gross negligence or willful misconduct by the Agent as the issuer
of Letters of Credit, the Agent shall not be liable for any error, omission,
interruption or delay, EVEN IF DUE TO THE NEGLIGENCE, WHETHER SOLE OR
CONCURRENT, OF THE AGENT, in transmission, dispatch or delivery of any message
or advice, however transmitted, in connection with any Letter of Credit. The
Agent, the Lenders, and the Borrowers agree that any action taken or omitted by
the Agent, as issuer of any Letter of Credit, under or in connection with any
Letter of Credit or the related drafts or documents, EVEN IF DUE TO THE
NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT OR ANY LENDER, if done in
the absence of gross negligence or willful misconduct, shall be binding as among
the Agent, as issuer of such Letter of Credit or otherwise, the Lenders, and the
Borrowers and shall not put the Agent, as issuer of such Letter of Credit or
otherwise, or any Lender under any liability to the Borrowers; provided,
however, that no such action taken or omitted to be taken by the Agent shall be
binding upon the Borrowers as against any Person other than the Agent and the
Lenders. Notwithstanding any provision to the contrary in this Section 2.21 or
elsewhere in this Agreement, the Agent, as the issuer of the Letters of Credit,
agrees to exercise ordinary care in examining each document required to be
presented pursuant to each Letter of Credit to ascertain that each such document
appears on its face to comply with the terms thereof.

      2.22 Yield Protection.

            (a) Without limiting the effect of the other provisions of this
      Section (but without duplication), the Borrowers shall pay to the Agent
      and each Lender from time to time, within five (5) Business Days of
      receipt of the certificate provided for in Section 2.22(e), such amounts
      as the Agent or such Lender may reasonably determine are necessary to
      compensate it for any Additional Costs incurred by the Agent or such
      Lender.

            (b) Without limiting the effect of the other provisions of this
      Section (but without duplication), the Borrowers shall pay to each Lender
      from time to time, within five Business Days of receipt of the certificate
      provided for in Section 2.22(e), such amounts as such Lender may determine
      are necessary to compensate such Lender for any actual costs incurred by
      such Lender attributable to the maintenance by such Lender (or any
      Applicable Lending Office), pursuant to any Regulatory Change, of capital
      (other than the Reserve Requirement utilized in the determination of any
      Adjusted LIBO Rate or the Adjusted CD Rate) in respect of its Commitments,
      such compensation to include an amount equal to any reduction of the rate
      of return on assets or equity of such Lender (or any Applicable Lending
      Office) to a level


                                       38
<PAGE>   44

      below that which such Lender (or any Applicable Lending Office) could have
      achieved but for such Regulatory Change.

            (c) Without limiting the effect of the other provisions of this
      Section (but without duplication), in the event that any Regulatory Change
      or the compliance by the Agent or any Lender therewith shall (i) impose,
      modify, or hold applicable any reserve, special deposit, or similar
      requirement against any Letter of Credit or obligation to issue Letters of
      Credit, or (ii) impose upon the Agent or such Lender any other condition
      regarding any Letter of Credit or obligation to issue Letters of Credit,
      and the result of any such event shall be to increase the cost to the
      Agent or such Lender of issuing or maintaining any Letter of Credit or
      obligation to issue Letters of Credit or any liability with respect to
      Letter of Credit Payments, or to reduce any amount receivable in
      connection therewith, then, within five Business Days of receipt of the
      certificate provided for in Section 2.22(e), the Borrowers shall pay to
      the Agent or such Lender, as the case may be, from time to time as
      specified by the Agent or such Lender, the additional amounts indicated in
      such certificate as sufficient to compensate the Agent or such Lender for
      such increased cost or reduced amount receivable.

            (d) Without limiting the effect of the other provisions of this
      Section (but without duplication), the Borrowers shall pay to the Agent
      and each Lender such amounts as shall be indicated in such certificate as
      sufficient to compensate them for any loss, cost, or expense incurred by
      and as a result of:

                  (i) any payment, prepayment, or conversion by the Borrowers of
      a LIBO Rate Loan on a date other than the last day of an Interest Period
      for such Loan; or

                  (ii) any failure by the Borrowers to borrow a LIBO Rate Loan
      or to convert a Base Rate Loan into a LIBO Rate Loan on the date for such
      borrowing or conversion specified in the relevant Borrowing Request;

such compensation to include with respect to any LIBO Rate Loan, an amount equal
to the excess, if any, of (A) the amount of interest which would have accrued on
the principal amount so paid, prepaid, converted, or not borrowed or converted
for the period from the date of such payment, prepayment, conversion, or failure
to borrow or convert to the last day of the then current Interest Period for
such Loan (or, in the case of a failure to borrow or convert, the Interest
Period for such Loan which would have commenced on the date of such failure to
borrow or convert) at the applicable rate of interest for such Loan provided for
herein over (B) the interest component of the amount the Agent or such Lender
bid in the London interbank market in respect of such Loan for Dollar deposits
of amounts comparable to such principal amount and maturities comparable to such
period, as reasonably determined by the Agent or such Lender.

            (e) Determinations by the Agent or any Lender for purposes of this
      Section of the effect of any Regulatory Change on capital maintained, its
      costs or rate of return, maintaining Loans, issuing Letters of Credit, its
      obligation to make Loans and issue Letters of Credit, or on amounts
      receivable by it in respect of Loans, Letters of Credit, or such
      obligations, and the additional amounts required to compensate the Agent
      and such Lender under this Section


                                       39
<PAGE>   45

      shall be conclusive, absent manifest error, provided that such
      determinations are made on a reasonable basis. The Agent or the relevant
      Lender shall furnish the Borrowers with a certificate setting forth in
      reasonable detail the basis and amount of increased costs incurred or
      reduced amounts receivable as a result of any such event, and the
      statements set forth therein shall be conclusive, absent manifest error.
      The Agent or the relevant Lender shall (i) notify the Borrowers, as
      promptly as practicable after the Agent or such Lender obtains knowledge
      of any Additional Costs or other sums payable pursuant to this Section and
      determines to request compensation therefor, in respect of any event
      occurring after the Closing Date which will entitle the Agent or such
      Lender to compensation pursuant to this Section; provided that the
      Borrowers shall not be obligated for the payment of any Additional Costs
      or other sums payable pursuant to this Section to the extent such
      Additional Costs or other sums accrued more than 90 days prior to the date
      upon which the Borrowers were given such notice; and (ii) designate a
      different Applicable Lending Office for the Loans affected by such event
      if such designation will avoid the need for or reduce the amount of such
      compensation and will not, in the sole opinion of the Agent or such
      Lender, be disadvantageous to the Agent or such Lender. Any compensation
      requested by the Agent or any Lender pursuant to this Section shall be due
      and payable within five Business Days of delivery of any such notice to
      the Borrowers.

      2.23 Illegality. Notwithstanding any other provision of this Agreement, in
the event that it becomes unlawful for any Lender or its Applicable Lending
Office to (a) honor its obligation to make LIBO Rate Loans, or (b) maintain LIBO
Rate Loans, then such Lender shall promptly notify the Agent and the Borrowers
thereof. The obligation of such Lender to make LIBO Rate Loans and convert Base
Rate Loans into LIBO Rate Loans shall then be suspended until such time as such
Lender may again make and maintain LIBO Rate Loans, and the outstanding LIBO
Rate Loans of such Lender shall be converted into Base Rate Loans in accordance
with Section 2.14; provided, however, each Lender shall use reasonable efforts
to designate a different Applicable Lending Office with respect to any LIBO Rate
Loan affected by the matters or circumstances described in this Section to avoid
the results provided in this Section if possible, so long as such designation is
not disadvantageous to the Lenders as determined by them in their sole
discretion.

      2.24 Taxes.

            (a) All payments made by the Borrowers under this Agreement shall be
      made free and clear of, and without reduction or withholding for or on
      account of, present or future income, stamp or other taxes, levies,
      imposts, duties, charges, fees, deductions or withholdings, hereafter
      imposed, levied, collected, withheld or assessed by any Governmental
      Authority on the basis of any change after the date hereof in any
      applicable treaty, law, rule, guideline or regulations or in the
      interpretation or administration thereof, excluding, in the case of the
      Agent and each Lender, income and franchise taxes (whether based upon net
      income, capital or profits) imposed on the Agent or such Lender (all such
      non-excluded taxes, levies, imposts, deductions, charges or withholdings
      being hereinafter called "Taxes"). If any Taxes are required to be
      withheld from any amounts payable to the Agent or any Lender hereunder or
      under any other Loan Document, the amounts so payable to the Agent or such
      Lender shall be increased to the extent necessary to yield to the Agent or
      such Lender (after payment of all Taxes) interest or any such other
      amounts payable hereunder at the rates or in the amounts


                                       40
<PAGE>   46

      specified in this Agreement and the other Loan Documents. Whenever any
      Taxes are payable by the Borrowers, promptly thereafter the Borrowers
      shall send to the Agent for its own account or for the account of such
      Lender, as the case may be, a certified copy of an original official
      receipt received by the Borrowers showing payment thereof. If any Borrower
      fails to pay any Taxes when due to the appropriate taxing authority or
      fails to remit to the Agent the required receipts or other required
      documentary evidence, such Borrower shall indemnify the Agent and the
      Lenders for any incremental taxes, interest or penalties that may become
      payable by the Agent or any Lender as a result of any such failure. The
      agreements in this Section shall survive the termination of this Agreement
      and the payment of all Obligations.

            (b) Each Lender that is not incorporated under the laws of the
      United States of America or a state thereof agrees that, on the date
      hereof or, if it becomes a Lender in accordance with Section 9.1, on the
      date of the applicable Assignment Agreement, it will, to the extent it may
      lawfully do so, deliver to the Borrowers and the Agent two duly completed
      copies of United States Internal Revenue Service Form W-8, 1001 or 4224 or
      any other applicable form, as the case may be, certifying in each case
      that such Lender is entitled to receive payments under any Loan Document,
      without deduction or withholding of any United States federal income
      taxes. At the written request of the Borrowers, each Lender which delivers
      to the Borrowers and the Agent a form pursuant to the preceding sentence
      further undertakes to deliver to the Borrowers and the Agent two further
      copies of such form, or successor applicable forms, or other manner of
      certification, as the case may be, on or before the date that any such
      letter or form expires or becomes obsolete or after the occurrence of any
      event requiring a change in the most recent form previously delivered by
      it to the Borrowers, and such extensions or renewals thereof as may
      reasonably be requested by the Borrowers, certifying in the case of each
      such form that such Lender is entitled to receive payments under any Loan
      Document without deduction or withholding of any United States federal
      income taxes, unless in any such case, an event (including any change in
      treaty, law or regulation) has occurred prior to the date on which any
      such delivery would otherwise be required which renders all such forms
      inapplicable or which would prevent such Lender from duly completing and
      delivering any such form with respect to it and such Lender advises the
      Borrowers that it is not capable of receiving payments without any
      deduction or withholding of United States federal income tax.

      2.25 Replacement Lenders.

            (a) If any Lender (i) has notified the Borrowers of its incurring
      additional costs under Section 2.22 or the illegality of LIBO Rate Loans
      under Section 2.23, (ii) has required the Borrowers to make payments for
      Taxes under Section 2.24, or (iii) has informed any Borrower of a
      Regulatory Change in accordance with Section 2.26, or if any Tranche A
      Lender is not in agreement with the amount of any Borrowing Base
      redetermination which a group of Tranche A Lenders constituting at least
      the Tranche A Required Lenders has approved, or if any Tranche B Lender is
      not in agreement with the amount of any Tranche B Borrowing Base
      redetermination which a group of Tranche B Lenders constituting at least
      the Tranche B Required Lenders has approved, then in any such event the
      Borrowers may, unless such Lender has notified the Borrowers that the
      circumstances giving rise to such


                                       41
<PAGE>   47

      notice no longer apply, terminate, in whole but not in part, the
      Commitments or the Tranche B Commitment of such Lender (other than the
      Agent) (the "Terminated Lender") at any time upon five Business Days'
      prior written notice to the Terminated Lender and the Agent (such notice
      referred to herein as a "Notice of Termination").

            (b) In order to effect the termination of the Commitments or the
      Tranche B Commitment of the Terminated Lender, the Borrowers shall (i)
      obtain an agreement with one or more Lenders to increase their Commitments
      and/or become a Tranche B Lender (ii) request any one or more other
      banking institutions to become a "Lender" in place and instead of such
      Terminated Lender and agree to accept its Commitments; provided, however,
      that such one or more other banking institutions are reasonably acceptable
      to the Agent and become parties by executing an Assignment Agreement (the
      Lenders or other banking institutions that agree to accept in whole or in
      part the Commitments or the Tranche B Commitment of the Terminated Lender
      being referred to herein as the "Replacement Lenders"), such that the
      aggregate increased and/or accepted Total Facility Amounts of the
      Replacement Lenders under clauses (i) and (ii) above equal the Tranche A
      Facility Amount and the Tranche B Facility Amount (if any) of the
      Terminated Lender and provided further, no Person may become a Tranche B
      Lender hereunder unless such Person also is or becomes a Tranche A Lender.

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

      all respects for the Terminated Lender to the extent of such assignment
      from and after such date with like effect as if becoming a Lender pursuant
      to the terms of Section 9.1(b), and the Terminated Lender will have the
      rights and benefits of an assignor under Section 9.1(b). To the extent not
      in conflict, the terms of Section 9.1(b) shall supplement the provisions

      2.26 Regulatory Change. In the event that by reason of any Regulatory
Change, any Lender (a) incurs Additional Costs based on or measured by the
excess above a specified level of the amount of a category of deposits or other
liabilities of such Lender which includes deposits by reference to which the
interest rate on any LIBO Rate Loan is determined as provided in this Agreement
or a category of extensions of credit or other assets of such Lender which
includes any LIBO Rate Loan, or (b) becomes subject to restrictions on the
amount of such a category of liabilities or assets which it may hold, then, at
the election of such Lender with notice to the Agent and the Borrowers setting
forth in reasonable detail a calculation of such Additional Costs or a
description of such restrictions, the obligation of such Lender to make LIBO
Rate Loans and to convert Base Rate Loans into LIBO Rate Loans shall be
suspended until such time as such Regulatory Change or other circumstance ceases
to be in effect, and all such outstanding LIBO Rate Loans shall be converted
into Base Rate Loans in accordance with Section 2.14.

      2.27 Non-Recourse to KCS. Notwithstanding any other provision of this
Agreement, the Notes or any of the other Loan Documents executed and delivered
by KCS in connection with or as security for the Obligations, except as
expressly hereinafter provided in this Section 2.27, KCS shall not be liable for
payment of amounts owing under and pursuant to the Obligations and the sole
recourse of the Agent and the Lenders for satisfaction of the Obligations with
respect to KCS shall be the liens, security interests and agreements created and
granted by KCS pursuant to the Stock Pledge Agreement and any other collateral
security documents to which KCS is now or may be a party to in the future. It is
expressly understood and agreed that (i) the Stock Pledge Agreement and (ii)
Section 4.7 of this Agreement contain various warranties, representations,
covenants and/or agreements made by KCS. To the extent that a breach of any of
such warranties, representations, covenants and/or agreements is or becomes an
Event of Default or otherwise gives rise to rights or actions (other than claims
of personal liability against KCS) by the Agent and the Lenders, the aforesaid
lack of personal liability shall not limit, modify, diminish or negate any such
right or actions, including without limitation (i) those relating to foreclosure
of liens, and/or security interests created pursuant to the Loan Documents and
(ii) those relating to enforcement of such personal liability as may exist for
breach of warranty or representation made in the Stock Pledge Agreement or
Section 4.7 of this Agreement, fraud or defalcation.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

            To induce the Agent and the Lenders to enter into this Agreement and
to extend credit to the Borrowers, each Borrower represents and warrants to the
Agent and each Lender (which representations and warranties shall survive the
delivery of the Notes) that:

      4.1 Due Authorization. The execution and delivery by the Borrowers of this
Agreement and the borrowings hereunder, the execution and delivery by the
Borrowers of the Notes and the other Loan Documents, the repayment of the Notes
and interest and fees provided for in the Notes and this Agreement, and the
performance of all obligations of the Borrowers under the Loan Documents are
within the power of the Borrowers, have been duly authorized by all necessary
corporate action by the Borrowers, and do not and will not (a) require the
consent of any Governmental Authority to be obtained by any Borrower, (b)
contravene or conflict with any Requirement of Law applicable to any Borrower or
the articles or certificate of incorporation, bylaws, or other organizational or
governing documents of the Borrowers, (c) contravene or conflict with any
material indenture, instrument, or other agreement, or any indenture,
instrument, or other agreement that, when aggregated with other such agreements,
is material, to which any Borrower is a party or by which any Property of any
Borrower may be presently bound or encumbered, except as could not reasonably be
expected to have a Material Adverse Effect, (d) contravene or conflict with any
indenture, instrument, or other agreement by which any item of Collateral is
bound or to which any such item of Collateral is subject, except as could not
reasonably be expected to have a Material Adverse Effect, or (e) result in or
require the creation or imposition of any Lien in, upon or of any Property of
any Borrower under any such indenture, instrument, or other agreement, other
than the Loan Documents.

      4.2 Corporate Existence. Each Borrower is a corporation duly organized,
legally existing, and in good standing under the laws of its state of
incorporation and is duly qualified as a foreign corporation and is in good
standing in all jurisdictions wherein the ownership of Property or the operation
of its business necessitates same, other than those jurisdictions wherein the
failure to so qualify will not have a Material Adverse Effect.

      4.3 Valid and Binding Obligations. All Loan Documents to which each
Borrower is a party, when duly executed and delivered by such Borrower, will be
the legal, valid, and binding obligations of the Borrower, enforceable against
such Borrower in accordance with its respective terms except as limited by
bankruptcy, insolvency or similar laws affecting generally the rights of
creditors and general principles of equity, whether applied by a court of law or
equity.

      4.4 Existing Indebtedness; No Defenses. As of the date hereof, (a) the
Borrowers are indebted in the aggregate principal amounts set forth in Exhibit X
under the heading "Existing Indebtedness", and (b) the Borrowers have no
defenses to, rights of setoff against, claims or


                                       47
<PAGE>   53

counterclaims with respect to, and no default exists under or with respect to
any Indebtedness or obligation of the Borrowers evidenced thereby.

      4.5 Security Instruments. The provisions of each Security Instrument
executed by any Borrower or any Substitute Mortgagor are effective to create in
favor of the Agent or the Collateral Agent, a legal, valid, and enforceable Lien
in all right, title, and interest of such Person in the Collateral described
therein, which Liens, assuming the accomplishment of recording and filing in
accordance with applicable laws prior to the intervention of rights of other
Persons, shall constitute fully perfected first-priority Liens on all right,
title, and interest of such Person in the Collateral described therein except
for Permitted Liens.

      4.6 Title to Assets. Except as heretofore disclosed to the Agent in
writing, insofar as such Property constitutes real property or interests in real
property, each of the Borrowers has good and indefeasible title to all of its
Mortgaged Properties and all of its other Properties which are material, free
and clear of Liens, except Permitted Liens. With respect to Property which does
not constitute real property or an interest in real property, each of the
Borrowers owns all such other Properties which are material, free and clear of
all Liens, except Permitted Liens and Liens otherwise permitted under Section
6.3.

      4.7 Scope and Accuracy of Financial Statements. The Financial Statements
of KCS and its Subsidiaries as of December 31, 1997 and September 30, 1998
(subject, in the case of the Financial Statements as of September 30, 1998, to
normal year-end audit adjustments), present fairly the financial position and
results of operations and cash flows of KCS and its Subsidiaries in accordance
with GAAP as at the relevant point in time or for the period indicated, as
applicable. No event or circumstance has occurred since September 30, 1998
except for the material decline of oil and gas prices generally, which could
reasonably be expected to have a Material Adverse Effect on KCS or KCS
Medallion.

      4.8 No Material Misstatements. All written estimates, projections and
forecasts furnished by or on behalf of the Borrowers to the Agent or any of the
Lenders for purposes of or in connection with this Agreement, or in connection
with any extension of credit hereunder, were and will be prepared on the basis
of the good faith estimate of the Borrowers' senior management concerning
probable financial condition and performance based on assumptions, data, tests
or conditions believed to be reasonable or to represent industry conditions
existing at the time such estimates, projections or forecasts were made. No
other information, exhibit, statement, or report furnished to the Agent or any
Lender by or at the direction of the Borrowers in connection with this Agreement
contains any material misstatement of fact or omits to state a material fact or
any fact necessary to make the statements contained therein, in light of the
circumstances in which they were made, not misleading as of the date made or
deemed made.

      4.9 Liabilities and Litigation. Other than as listed under the heading
"Liabilities" on Exhibit X, the Borrowers have no liabilities, direct, or
contingent, which could reasonably be expected to have a Material Adverse Effect
on KCS or KCS Medallion. Except as set forth under the heading "Litigation" on
Exhibit X, no litigation or other action of any nature is pending before any
Governmental Authority or, to the best knowledge of such Borrowers, threatened,
against or affecting (a) any Collateral, or, in the case of Environmental Laws,
any Property of any Borrower,


                                       48
<PAGE>   54

or the facilities located and the operations conducted thereon, which, if
determined adversely to such Borrower, could reasonably be expected to have a
Material Adverse Effect on KCS or KCS Medallion, (b) any Borrower's ability to
enter into, execute, deliver or perform in any material respect its obligations
under the Loan Documents, (c) any Borrower which, if determined adversely to
such Borrower, could reasonably be expected to result in any judgment or
liability, individually or when aggregated with all other such judgments or
liabilities, which could reasonably be expected to have a Material Adverse
Effect on KCS or KCS Medallion and which is not fully covered by insurance
(exclusive of any deductible amount related to such insurance, which deductible
amount is customary for Persons engaged in similar businesses), or (d) any
Borrower, which if determined adversely to such Borrower, could reasonably be
expected to result in any other Material Adverse Effect on KCS or KCS Medallion.

      4.10 Authorizations; Consents. Except as expressly contemplated by this
Agreement, no authorization, consent, approval, exemption, franchise, permit, or
license of, or filing with, any Governmental Authority or any other Person is
required to be obtained by any Borrower to authorize, or is otherwise required
in connection with, the valid execution and delivery by the Borrowers of the
Loan Documents or any instrument contemplated hereby, the repayment by the
Borrowers of the Notes and interest and fees provided in the Notes and this
Agreement, or the performance by the Borrowers of the Obligations.

      4.11 Compliance with Laws. Each Borrower and its Property, are in
compliance with all applicable Requirements of Law, including Environmental
Laws, the Natural Gas Policy Act of 1978, as amended, and ERISA, other than any
Requirements of Laws the failure with which to comply, individually or in the
aggregate, could reasonably be expected not to cause a Material Adverse Effect.

      4.12 Default. None of the Borrowers is in default of, and no event has
occurred which, with the lapse of time or giving of notice, or both, could
result in such a default of, (i) any charter document or bylaws of any Borrower,
or (ii) any agreement or obligation other than an agreement or obligation
evidencing or relating to Debt to which any Borrower is a party or by which any
Property of any Borrower may be bound, pursuant to which the obligations of the
Borrowers in the aggregate under any such agreement or obligation, or the
obligations secured thereby, exceed $2,500,000, except such as are being
contested in good faith and as to which such reserve as may be required by GAAP
shall have been made therefore.

      4.13 ERISA. No Reportable Event has occurred with respect to any Single
Employer Plan, and each Single Employer Plan has complied with and been
administered in all material respects in accordance with applicable provisions
of ERISA and the Code. To the best knowledge of the Borrowers, (a) no Reportable
Event has occurred with respect to any Multiemployer Plan, and (b) each
Multiemployer Plan has complied with and been administered in all material
respects with applicable provisions of ERISA and the Code. Each Plan satisfied
the minimum funding requirements under ERISA and the Code as of the last annual
valuation date applicable thereto. Neither the Borrowers nor any Commonly
Controlled Entity has had a complete or partial withdrawal from any
Multiemployer Plan for which there is any withdrawal liability. As of the most
recent valuation date applicable to any Multiemployer Plan, neither the
Borrowers nor any Commonly Controlled Entity would become subject to any
liability under ERISA if the Borrower


                                       49
<PAGE>   55

or such Commonly Controlled Entity were to withdraw completely from such
Multiemployer Plan. Neither any Borrower nor any Commonly Controlled Entity has
received notice that any Multiemployer Plan is Insolvent or in Reorganization.
To the best knowledge of the Borrowers, no such Insolvency or Reorganization
which could reasonably be expected to have a Material Adverse Effect is likely
to occur. Based upon GAAP existing as of the date of this Agreement and current
factual circumstances, the Borrowers have no reason to believe that the annual
cost during the term of this Agreement to the Borrowers and all Commonly
Controlled Entities for post-retirement benefits to be provided to the current
and former employees of the Borrowers and all Commonly Controlled Entities under
Plans which are welfare benefit plans (as defined in Section 3(1) of ERISA)
will, in the aggregate, have a Material Adverse Effect.

      4.14 Environmental Laws. To the best knowledge and belief of the
Borrowers, except for matters listed below in this Section 4.14 which could not
reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect, and except as described on Exhibit X under the heading
"Environmental Matters:"

            (a) no Property of any Borrower is currently on or has ever been on,
      any federal or state list of Superfund Sites;

            (b) no Hazardous Substances have been generated, transported, and/or
      disposed of by any Borrower at a site which was, at the time of such
      generation, transportation, and/or disposal, or has since become, a
      Superfund Site;

            (c) except in accordance with applicable Requirements of Law or the
      terms of a valid permit, license, certificate, or approval of the relevant
      Governmental Authority, no Release of Hazardous Substances has occurred by
      any Borrower or from, affecting, or related to any Property of any
      Borrower or the facilities located and the operations conducted thereon;
      and

            (d) no Environmental Complaint has been received by any Borrower.

      4.15 Compliance with Federal Reserve Regulations. No transaction
contemplated by the Loan Documents is in violation of any regulations
promulgated by the Board of Governors of the Federal Reserve System, including
Regulations G, T, U, or X.

      4.16 Investment Company Act Compliance. None of the Borrowers is, nor is
any Borrower directly or indirectly controlled by or acting on behalf of any
Person which is, an "investment company" or an "affiliated person" of an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

      4.17 Public Utility Holding Company Act Compliance. No Borrower is a
"holding company," or an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company," within the meaning of the Public Utility
Holding Company Act of 1935, as amended.

      4.18 Proper Filing of Tax Returns; Payment of Taxes Due. Each Borrower has
duly and properly filed its United States income tax returns and all other tax
returns which are required to be


                                       50
<PAGE>   56

filed and has paid all taxes shown to be due thereon, except such as are being
contested in good faith and as to which adequate provisions and disclosures have
been made and except such returns of which the failure to file has not had or
would not have a Material Adverse Effect. The respective charges and reserves on
the books of each Borrower with respect to taxes and other governmental charges
are adequate.

      4.19 Refunds. Except as described on Exhibit X under the heading
"Refunds," to the best knowledge and belief of the Borrowers, no orders of,
proceedings pending before, or other requirements of, the Federal Energy
Regulatory Commission or any other Governmental Authority exist which could
reasonably be expected to result in the Borrowers being required to refund any
material portion of the proceeds received or to be received from the sale of
hydrocarbons constituting part of the Mortgaged Property.

"Gas Contracts," as of the Closing Date, (a) no Borrower is obligated in any
material respect by virtue of any prepayment made under any contract containing
a "take-or-pay" or "prepayment" provision or under any similar agreement to
deliver hydrocarbons produced from or allocated to any of the Mortgaged Property
at some future date without receiving full payment therefor within 90 days of

currently conducted. No claim has been asserted or is pending by any Person with
respect to the use of any such Intellectual Property or challenging or
questioning the validity or effectiveness of any such Intellectual Property; and
each Borrower knows of no valid basis for any such claim. The use of such
Intellectual Property by each Borrower does not infringe on the rights of any
Person, except for such claims and infringements as are not, in the aggregate,
likely to have a Material Adverse Effect.

      4.22 Labor Matters. Except as disclosed on Exhibit X under the heading
"Labor Matters," as of the Closing Date there are no collective bargaining
agreements covering the employees of any of the Borrowers or any Affiliates of
any of the Borrowers. None of such Persons has suffered any strikes, walkouts,
work stoppages or other material labor difficulty within the last five years,
other than those which could not reasonably be expected to have a Material
Adverse Effect.

Effect has occurred with respect to the business nor any Property of any

windstorm, accident, strike or other labor disturbance, embargo, requisition or
taking of Property, or cancellation of contracts, permits, or concessions by any
Governmental Authority, riot, activities of armed forces, or acts of God.

on the part of the Agent, the Collateral Agent, or any Lender or any of their
respective shareholders, officers, directors, employees, agents,
attorneys-in-fact, or affiliates or any trustee for the benefit of the Agent,
the Collateral Agent, or the Lenders under any Security Instrument; provided,
however, the foregoing clauses (a) through (e) shall not apply to any claim,
loss, damage, liability, fine, penalty, charge, proceeding, order, judgment,
action or requirement attributable to (i) the gross negligence or willful
misconduct of any Person to be indemnified or (ii) any action or inaction of any
Person to be indemnified subsequent to the exercise of ownership rights or the
taking of any foreclosure action with respect to any of the Collateral and with
respect to such Collateral such claim, loss, damage, liability, fine, penalty,
charge, proceeding, order, judgment, action or requirement arises subsequent to

under any


                                       58

realization against any Collateral or the conveyance of any Property in lieu
thereof.

                                    THE AGENT

      8.1 Appointment. Each Lender hereby designates and appoints CIBC as the

<PAGE>   72

Lender authorizes the Agent and the Collateral Agent to take such action on
behalf of such Lender under the provisions of this Agreement and the other Loan
Documents and to exercise such powers and perform such duties as are expressly
delegated to the Agent and the Collateral Agent by the terms of this Agreement
and the other Loan Documents, together with such other powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary elsewhere in
this Agreement or in any other Loan Document, neither the Agent nor the
Collateral Agent shall have any duties or responsibilities except those
expressly set forth herein or in any other Loan Document or any fiduciary
relationship with any Lender; and no implied covenants, functions,
responsibilities, duties, obligations, or liabilities on the part of the Agent
or the Collateral Agent shall be read into this Agreement or any other Loan
Document or otherwise exist against the Agent or the Collateral Agent.

      8.2 Delegation of Duties. Each of the Agent and the Collateral Agent may
execute any of its duties under this Agreement and the other Loan Documents by
or through agents or attorneys-in-fact and shall be entitled to advice of
counsel concerning all matters pertaining to such duties. Neither the Agent nor
the Collateral Agent shall be responsible for the negligence or misconduct of
any agents or attorneys-in-fact selected by it with reasonable care.

      8.3 Exculpatory Provisions. Neither the Agent, the Collateral Agent, nor
any of their respective officers, directors, employees, agents,
attorneys-in-fact or affiliates shall be (a) required to initiate or conduct any
litigation or collection proceedings hereunder, except with the concurrence of
the Required Lenders and contribution by each Lender of its Percentage Share of
costs reasonably expected by the Agent or the Collateral Agent to be incurred in
connection therewith, (b) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except for gross negligence or willful misconduct of the
Agent, the Collateral Agent, or such Person), or (c) responsible in any manner
to any Lender for any recitals, statements, representations or warranties made
by the Borrowers or any officer thereof contained in this Agreement or any other
Loan Document or in any certificate, report, statement or other document
referred to or provided for in, or received by the Agent or the Collateral Agent
under or in connection with, this Agreement or any other Loan Document, or for
the value, validity, effectiveness, genuineness, enforceability or sufficiency
of this Agreement or any other Loan Document or for any failure of the Borrower
to perform its obligations hereunder or thereunder. Neither the Agent nor the
Collateral Agent shall 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 the Borrowers.

      8.4 Reliance by Agent. Each of the Agent and the Collateral Agent shall be
entitled to rely, and shall be fully protected in relying, upon any Note,
writing, resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, telex or teletype message, statement, order or other
document or conversation believed by it to be 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 counsel to the Borrowers), independent
accountants and other experts selected by the


                                       67
<PAGE>   73

Agent or the Collateral Agent. Each of the Agent and the Collateral Agent may
deem and treat the payee of any Note as the owner thereof for all purposes
unless and until a written notice of assignment, negotiation, or transfer
thereof shall have been received by the Agent. Each of the Agent and the
Collateral Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of the Required Lenders as it deems
appropriate or of all of the Lenders if required by any provision of this
Agreement and contribution by each Lender of its Percentage Share of costs
reasonably expected by the Agent or the Collateral Agent, as the case may be, to
be incurred in connection therewith. Each of the Agent and the Collateral Agent
shall in all cases be fully protected in acting, or in refraining from acting,
under this Agreement and the other Loan Documents in accordance with a request
of the Required Lenders. Such request and any action taken or failure to act
pursuant thereto shall be binding upon the Lenders and all future holders of the
Notes. In no event shall either the Agent or the Collateral Agent be required to
take any action that exposes such agent to personal liability or that is
contrary to any Loan Document or applicable Requirement of Law.

      8.5 Notice of Default. Neither the Agent nor the Collateral Agent shall be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default unless such agent has received notice from a Lender or the Borrowers
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default." In the event that such agent
receives such a notice, such agent shall promptly give notice thereof to the
Lenders. The Agent and the Collateral Agent shall take such action with respect
to such Default or Event of Default as shall be reasonably directed by the
Required Lenders; provided that unless and until the Agent and the Collateral
Agent shall have received such directions, subject to the provisions of Section
7.2, each of the Agent and the Collateral Agent may (but shall not be obligated
to) take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable in the best interests of
the Lenders. In the event that the officer of the Agent or the Collateral Agent
primarily responsible for the lending relationship with the Borrowers or the
officer of any Lender primarily responsible for the lending relationship with
the Borrowers becomes aware that a Default or Event of Default has occurred and
is continuing, such agent or such Lender, as the case may be, shall use its good
faith efforts to inform the other Lenders and/or the other agents, as the case
may be, promptly of such occurrence. Notwithstanding the preceding sentence,
failure to comply with the preceding sentence shall not result in any liability
to the Agent, the Collateral Agent, or any Lender.

      8.6 Non-Reliance on Agent and Other Lenders. Each Lender expressly
acknowledges that neither the Agent, the Collateral Agent, any other Lender nor
any of their respective officers, directors, employees, agents,
attorneys-in-fact or affiliates has made any representation or warranty to such
Lender and that no act by the Agent, the Collateral Agent, or any other Lender
hereafter taken, including any review of the affairs of the Borrowers, shall be
deemed to constitute any representation or warranty by the Agent, the Collateral
Agent, or any Lender to any other Lender. Each Lender represents to the Agent
and the Collateral Agent that it has, independently and without reliance upon
the Agent, the Collateral Agent, 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


                                       68
<PAGE>   74

business, operations, property, condition (financial and otherwise) and
creditworthiness of the Borrowers and the value of the Collateral and other
Properties of the Borrowers and has made its own decision to enter into this
Agreement. Each Lender also represents that it will, independently and without
reliance upon the Agent or the Collateral Agent or any other Lender and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own 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, condition (financial and otherwise) and creditworthiness
of the Borrowers and the value of the Collateral and other Properties of the
Borrowers. Except for notices, reports and other documents expressly required to
be furnished to the Lenders by the Agent or the Collateral Agent hereunder,
neither the Agent nor the Collateral Agent shall have any duty or responsibility
to provide any Lender with any credit or other information concerning the
business, operations, property, condition (financial and otherwise), or
creditworthiness of the Borrowers or the value of the Collateral or other
Properties of the Borrowers which may come into the possession of the Agent, the
Collateral Agent or any of their respective officers, directors, employees,
agents, attorneys-in-fact or affiliates.

      8.7 Indemnification. EACH LENDER AGREES TO INDEMNIFY THE AGENT AND THE
COLLATERAL AGENT AND EACH OF THEIR OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
ATTORNEYS-IN-FACT AND AFFILIATES (TO THE EXTENT NOT REIMBURSED BY THE BORROWERS
AND WITHOUT LIMITING THE OBLIGATION OF THE BORROWERS TO DO SO), RATABLY
ACCORDING TO THE PERCENTAGE SHARE OF SUCH LENDER, FROM AND AGAINST ANY AND ALL
LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND WHATSOEVER WHICH
MAY AT ANY TIME (INCLUDING ANY TIME FOLLOWING THE PAYMENT AND PERFORMANCE OF ALL
OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT) BE IMPOSED ON, INCURRED BY OR
ASSERTED AGAINST THE AGENT, THE COLLATERAL AGENT OR ANY OF THEIR RESPECTIVE
OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES IN ANY
WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR
ANY OTHER DOCUMENT CONTEMPLATED OR REFERRED TO HEREIN OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR ANY ACTION TAKEN OR OMITTED BY THE AGENT, THE COLLATERAL
AGENT OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
ATTORNEYS-IN-FACT OR AFFILIATES UNDER OR IN CONNECTION WITH ANY OF THE
FOREGOING, INCLUDING ANY LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES,
PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS IMPOSED,
INCURRED OR ASSERTED AS A RESULT OF THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT,
OF THE AGENT, THE COLLATERAL AGENT OR ANY OF THEIR RESPECTIVE OFFICERS,
DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES; PROVIDED THAT NO
LENDER SHALL BE LIABLE FOR THE PAYMENT OF ANY PORTION OF SUCH LIABILITIES,
OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS,
EXPENSES OR DISBURSEMENTS RESULTING SOLELY FROM THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF THE AGENT, THE COLLATERAL AGENT OR ANY OF THEIR RESPECTIVE
OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES. THE
AGREEMENTS IN THIS SECTION


                                       69
<PAGE>   75

SHALL SURVIVE THE PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION
OF THIS AGREEMENT.

      8.8 Restitution. Should the right of the Agent, the Collateral Agent or
any Lender to realize funds with respect to the Obligations be challenged and
any application of such funds to the Obligations be reversed, whether by
Governmental Authority or otherwise, or should the Borrowers otherwise be
entitled to a refund or return of funds distributed to the Lenders in connection
with the Obligations, the Agent, the Collateral Agent or such Lender, as the
case may be, shall promptly notify the Lenders of such fact. Not later than
Noon, Eastern Standard or Daylight Savings Time, as the case may be, of the
Business Day following such notice, each Lender shall pay to the Agent an amount
equal to the ratable share of such Lender of the funds required to be returned
to the Borrowers. The ratable share of each Lender shall be determined on the
basis of the percentage of the payment all or a portion of which is required to
be refunded originally distributed to such Lender, if such percentage can be
determined, or, if such percentage cannot be determined, on the basis of the
Percentage Share of such Lender. The Agent shall forward such funds to the
Borrowers or to the Lender required to return such funds. If any such amount due
to the Agent is made available by any Lender after Noon, Eastern Standard or
Daylight Savings Time, as the case may be, of the Business Day following such
notice, such Lender shall pay to the Agent (or the Lender required to return
funds to the Borrowers, as the case may be) for its own account interest on such
amount at a rate equal to the Federal Funds Rate for the period from and
including the date on which restitution to the Borrowers is made by the Agent
(or the Lender required to return funds to the Borrowers, as the case may be) to
but not including the date on which such Lender failing to timely forward its
share of funds required to be returned to the Borrowers shall have made its
ratable share of such funds available.

      8.9 Agents in Individual Capacity. Each of the Agent and the Collateral
Agent and their affiliates may make loans to, accept deposits from and generally
engage in any kind of business with the Borrowers as though the Agent and the
Collateral Agent were not agents hereunder. With respect to any Note issued to
the Lender serving as the Collateral Agent, the Collateral Agent shall have the
same rights and powers under this Agreement as a Lender and may exercise such
rights and powers as though it were not the Collateral Agent. The terms "Lender"
and "Lenders" shall include the Collateral Agent in its individual capacity.

      8.10 Successor Agent. Provided that a successor agent has been appointed
and has accepted such appointment as provided below, the Agent or the Collateral
Agent may resign upon 30 days' notice to the Lenders and the Borrowers. If the
Agent or the Collateral Agent shall resign as an agent under this Agreement and
the other Loan Documents, Lenders for which the Percentage Shares of Tranche A
Commitments aggregate at least sixty-six and two-thirds percent (66-2/3%) shall
appoint from among the Lenders a successor agent or collateral agent, as the
case may be, for the Lenders, whereupon such successor agent shall succeed to
the rights, powers and duties of such agent. The term "Agent" or "Collateral
Agent" shall mean such successor agent effective upon its appointment. Upon
written acceptance by such successor agent (a copy of which shall be furnished
to the Borrowers), the rights, powers, and duties of the former agent as Agent
or Collateral Agent


                                       70
<PAGE>   76

shall be terminated, without any other or further act or deed on the part of
such former agent or any of the parties to this Agreement or any holders of the
Notes. After the resignation of the Agent or the Collateral Agent hereunder as
an agent, the provisions of this Article VIII and Sections 2.2(d), 5.13, and
5.17 shall inure to its benefit as to any actions taken or omitted to be taken
by it while it was an agent under this Agreement and the other Loan Documents.

      8.11 Applicable Parties. The provisions of this Article are solely for the
benefit of the Agent, the Collateral Agent and the Lenders, and the Borrowers
shall not have any rights as a third party beneficiary or otherwise or any
obligations under any of the provisions of this Article. In per forming
functions and duties hereunder and under the other Loan Documents, the Agent and
the Collateral Agent shall act solely as the agent of the Lenders and do not
assume, nor shall either be deemed to have assumed, any obligation or
relationship of trust or agency with or for the Borrowers or any legal
representative, successor, and assign of the Borrowers.

                                   ARTICLE IX

                                  MISCELLANEOUS

      9.1 Assignments; Participations.

            (a) The Borrowers may not assign any of their rights or obligations
      under any Loan Documents without the prior consent of the Agent and the
      Lenders.

            (b) With the consent of the Agent and the Borrowers (which consents
      shall not be unreasonably withheld), any Lender may assign to one or more
      assignees all or a portion of its rights and obligations under this
      Agreement pursuant to an Assignment Agreement; provided, however, that if
      the assigning Lender holds both Tranche A Loans and Tranche B Loans
      (and/or has a Tranche A Commitment and a Tranche B Commitment), then any
      assignment of any portion of the rights and obligations in respect of such
      Lender's Tranche B Loans and/or Tranche B Commitment or Tranche A Loans
      and/or Tranche A Commitment may only be made in conjunction with an
      assignment of a proportionate portion of its rights and obligations in
      respect of such Lender's Tranche A Loans and/or Tranche A Commitment or
      Tranche B Loans and/or Tranche B Commitment, respectively. Except with the
      consent of the Agent and the Borrowers (which consents shall not be
      unreasonably withheld) in the case of any assignment of any Tranche B
      Loans and/or Tranche B Commitment, any such assignment shall be in the
      amount of at least $10,000,000 in the case of a Tranche A assignment (or
      any whole multiple of $1,000,000 in excess thereof) and $1,000,000 in the
      case of a Tranche B assignment (or any whole multiple of $500,000 in
      excess thereof), and the assignee shall pay to the Agent a transfer fee in
      the amount of $3,500 for each such assignment. Any such assignment shall
      become effective upon the execution and delivery to the Agent of the
      Assignment Agreement and the consent of the Agent and the Borrowers.
      Promptly following receipt of an executed Assignment Agreement, the Agent
      shall send to


                                       71
<PAGE>   77

      the Borrowers a copy of such executed Assignment Agreement. Promptly
      following receipt of such executed Assignment Agreement, the Borrowers
      shall execute and deliver, at their own expense, new Notes to the assignee
      and, if applicable, the assignor, in accordance with their respective
      interests, whereupon the prior Notes of the assignor and, if applicable,
      the assignee, shall be canceled and returned to the Borrowers. Upon the
      effectiveness of any assignment pursuant to this Section 9.1(b), the
      assignee shall become a "Lender," if not already a "Lender," for all
      purposes of the Loan Documents, and the assignor shall be relieved of its
      obligations hereunder from and after the date of such assignment to the
      extent of such assignment. If the assignor no longer holds any rights or
      obligations under this Agreement, such assignor shall cease to be a
      "Lender" hereunder, except that its rights under Sections 2.21 and 5.18
      shall not be affected. On the last Business Day of each calendar quarter
      during which an assignment has become effective pursuant to this Section
      9.1(b), the Agent shall prepare a new Exhibit III giving effect to all
      such assignments effected during such month and will promptly provide a
      copy thereof to the Borrowers and each Lender.

            (c) Each Lender may transfer, grant, or assign participations in all
      or any portion of its interests hereunder to any Person pursuant to this
      Section 9.1(c), provided that such Lender shall remain a "Lender" for all
      purposes of this Agreement and the transferee of such participation shall
      not constitute a "Lender" hereunder. In the case of any such
      participation, the participant shall not have any rights under any Loan
      Document, the rights of the participant in respect of such participation
      to be against the granting Lender as set forth in the agreement with such
      Lender creating such participation, and all amounts payable by the
      Borrower hereunder shall be determined as if such Lender had not sold such
      participation. Each participation agreement shall provide that the Lender
      that has sold or granted the participation shall retain the sole right to
      take or refrain from taking any action under the Loan Documents, except
      that such participation agreement may provide that such Lender shall not,
      without the consent of the participant, agree to any amendment or waiver
      that would have the effect, to the extent any such amendment or waiver
      pertains to the type of Commitment(s) or Loan(s) of such participant so
      that such participant would be affected thereby, of (i) increasing the
      Commitments of such Lender, (ii) extending the Tranche A Commitment
      Termination Date, (iii) extending the Tranche B Commitment Termination
      Date, (iv) reducing the principal on the Loans, (v) reducing the rate of
      interest on the Loans or the Notes, (vi) reducing the amount of such
      Lender's participation in any fees payable pursuant to Sections 2.15 or
      2.16, or (vii) extending the time of scheduled payment of any Obligation.
      All amounts payable to any Lender under Article 2 shall be determined as
      if such Lender had not sold any participations. Each agreement creating a
      participation must include an agreement by the participant to be bound by
      the provisions of Section 9.9.

            (d) The Lenders may furnish any information concerning the Borrowers
      in the possession of the Lenders from time to time to assignees and
      participants and prospective assignees and participants, provided that
      such Persons agree to be bound by the provisions of Section 9.9.


                                       72
<PAGE>   78

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

            (f) Each Lender party to this Agreement on the Closing Date hereby
      represents, and each Person that becomes a lender pursuant to an
      Assignment Agreement will represent, and shall be deemed to have
      represented on becoming a party to this Agreement, that it is a bank or
      other financial institution regularly engaged in making or purchasing
      loans, that it will make or acquire Loans hereunder for its own account in
      the ordinary course of its business, and that it has capital surplus and
      undivided profits aggregating at least $500,000,000.

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

      9.2 Survival of Representations, Warranties, and Covenants. All
representations and warranties of the Borrowers and all covenants and agreements
herein made shall survive the execution and delivery of the Notes and the
Security Instruments and shall remain in force and effect so long as any
Obligation is outstanding or any Commitments exist.

      9.3 Notices and Other Communications. Except as to oral notices expressly
authorized herein, which oral notices shall be confirmed in writing, all
notices, requests, and communications hereunder or in connection herewith or
with any other Loan Document shall be in writing (including by telecopy). Unless
otherwise expressly provided herein, any such notice, request, demand, or other
communication shall be deemed to have been duly given or made when delivered by
hand, or, in the case of delivery by mail, two Business Days after deposited in
the mail, certified mail, return receipt requested, postage prepaid, or, in the
case of telecopy notice, when receipt thereof is acknowledged orally or by
written confirmation report, addressed to each party at the "Address for
Notices" specified below its name on the signature pages hereof or at such other
address within the United States as shall be designated by such party in a
notice given to the Agent and the Borrowers.

      9.4 Parties in Interest. Subject to the restrictions on changes in
corporate structure set forth in Section 6.10 and other applicable restrictions
contained herein, all covenants and agreements herein contained by or on behalf
of the Borrowers, the Agent, the Collateral Agent or the Lenders shall be
binding upon and inure to the benefit of the Borrowers, the Agent, the
Collateral Agent or the Lenders, as the case may be, and their respective legal
representatives, successors, and permitted assigns.


                                       73
<PAGE>   79

      9.5 Rights of Third Parties. All provisions herein are imposed solely and
exclusively for the benefit of the Agent, the Collateral Agent the Lenders and
the Borrowers and their successors and permitted assigns. No other Person shall
have any right, benefit, priority, or interest hereunder or as a result hereof
or have standing to require satisfaction of provisions hereof in accordance with
their terms.

      9.6 No Waiver; Rights Cumulative. No course of dealing on the part of the
Agent, the Collateral Agent or the Lenders or their officers or employees, nor
any failure or delay by the Agent, the Collateral Agent or the Lenders with
respect to exercising any of their rights under any Loan Document shall operate
as a waiver thereof. The rights of the Agent, the Collateral Agent and the
Lenders under the Loan Documents shall be cumulative and the exercise or partial
exercise of any such right shall not preclude the exercise of any other right.
Neither the making of any Loan nor the issuance of a Letter of Credit shall
constitute a waiver of any of the covenants, warranties, or conditions of the
Borrowers contained herein. In the event any Borrower is unable to satisfy any
such covenant, warranty, or condition, neither the making of any Loan nor the
issuance of a Letter of Credit shall have the effect of precluding the Agent or
the Lenders from thereafter declaring such inability to be an Event of Default
as hereinabove provided.

      9.7 Severability. In the event any one or more of the provisions contained
in any of the Loan Documents shall, for any reason, be held to be invalid,
illegal, or unenforceable in any respect, such invalidity, illegality, or
unenforceability shall not affect any other provision of any Loan Document.

      9.8 Amendments; Waivers. Neither this Agreement nor any of the other Loan
Documents nor any terms hereof or thereof may be amended, supplemented,
modified, or waived except in writing and in accordance with the provisions of
this Section. The Agent and the Borrowers may, from time to time with the
written consent of the Required Lenders, enter into written amendments,
supplements, or modifications to the Loan Documents for the purpose of adding
any provisions to this Agreement or the other Loan Documents or changing in any
manner the rights of the Lenders or the Borrowers hereunder or thereunder or
waiving, on such terms and conditions as the Agent may specify in such
instrument, any of the requirements of this Agreement or the other Loan
Documents or any Default or Event of Default and its consequences; provided,
however, that no such amendment, supplement, modification, or waiver shall (a)
extend the time of scheduled payment of any Obligation, change the rate of
interest thereon, extend the Tranche A Commitment Termination Date, extend the
Tranche B Commitment Termination Date or extend a Final Maturity, reduce any fee
payable for the account of the Lenders hereunder, release any, all or
substantially all of the Collateral, reduce the amount of any Obligation,
increase the Tranche A Commitment Amount or increase the Tranche B Commitment
Amount, except in accordance with Section 2.12 change the Borrowing Base or the
Tranche B Borrowing Base or any other provision applicable to the determination
of the Borrowing Base or the Tranche B Borrowing Base, or amend, modify, or
waive any provision of this Section or Sections 2.12, 5.13, 5.17 or 8.10, change
the percentage specified in the definition of the Tranche A Required Lenders or
the Tranche B Required Lenders, or consent to the assignment or transfer by the
Borrowers of any of their rights or obligations under this


                                       74
<PAGE>   80

Agreement or the other Loan Documents, in any such case without the written
consent of all Lenders, (b) amend, modify, or waive any provision of Article
VIII or the rights or obligations of the Agent (including its rights and
obligations as issuer of the Letters of Credit) or the Collateral Agent without
the written consent of such agent, or (c) amend, modify, or waive any provision
relating to any Hedging Agreement without the written consent of the Lender
party thereto or whose affiliate is a party thereto. Any such amendment,
supplement, modification, or waiver shall apply equally to each of the Lenders
(taking into account the differences between the Tranche A Commitment and the
Tranche B Commitment) and shall be binding upon the Borrowers, the Lenders, the
Agent, and the Collateral Agent and all future holders of the Notes.
Notwithstanding the foregoing, during each Sales Period, the Collateral Agent
may, provided that no Default or Event of Default exists, release items of
Collateral sold by the Borrowers in accordance with Section 6.5. In the event of
any waiver, the Borrowers, the Lenders, the Agent, and the Collateral Agent
shall be restored to their respective former positions and rights hereunder and
under the other Loan Documents, and any Default or Event of Default waived shall
be deemed to be cured and not continuing; but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any right with respect
thereto.

      9.9 Confidentiality. In the event that any Borrower provides to the Agent,
the Collateral Agent or the Lenders information belonging to any Borrower or any
Affiliate of the Borrowers, the Agent, the Collateral Agent and the Lenders
shall thereafter maintain such information in confidence. This obligation of
confidence shall not apply to such portions of the information which (i) are in
the public domain, (ii) hereafter become part of the public domain without the
Agent, the Collateral Agent or the Lenders breaching their obligation of
confidence herein or in any other Loan Document, (iii) are previously known by
the Agent, the Collateral Agent or the Lenders from some source other than the
Borrowers or any Affiliate of the Borrowers, (iv) are hereafter developed by the
Agent, the Collateral Agent or the Lenders without using the information thus
provided, (v) are hereafter obtained by or available to the Agent, the
Collateral Agent or the Lenders from a third party who owes no obligation of
confidence to the Borrowers or any Affiliate of the Borrowers with respect to
such information or through any other means other than through disclosure by the
Borrowers or any Affiliate of the Borrowers to the Agent, the Collateral Agent
or the Lenders, (vi) are disclosed with the Borrowers' consent, (vii) must be
disclosed pursuant to any Requirement of Law, (viii) as may be required by law
or regulation or order of any Governmental Authority in any judicial,
arbitration or governmental proceeding or (ix) as may be requested by any
Governmental Authority pursuant to any bank examination or audit; provided,
however, that to the extent practicable and unless otherwise prohibited by any
Requirement of Law, any Person disclosing any non-public information pursuant to
clauses (vii) or (viii) shall endeavor in good faith to give the Borrowers at
least 5 days' prior written notice of such disclosure. Further, the Agent, the
Collateral Agent or a Lender may disclose any such information to any other
Lender or successor agent, any independent petroleum engineers or consultants,
any independent certified public accountants, any legal counsel employed by such
Person in connection with this Agreement or any other Loan Document, including
the enforcement or exercise of all rights and remedies hereunder or thereunder,
or any assignee or participant (including prospective assignees and
participants) in the Loans; provided, however, that the Agent, the Collateral
Agent or the Lenders impose on the Person to whom such information is


                                       75
<PAGE>   81

disclosed the same obligation to maintain the confidentiality of such
information as is imposed upon it hereunder and such Person agrees to be bound
by the terms hereof. Notwithstanding anything to the contrary provided herein,
this obligation of confidence shall cease three (3) years from the later of (a)
the later to occur of the Final Maturity of the Tranche A Notes or the Final
Maturity of the Tranche B Notes or (b) the date that all Obligations are paid or
satisfied in full or otherwise performed or discharged or deemed performed or
discharged.

      9.10 Controlling Agreement. In the event of a conflict between the
provisions of this Agreement and those of any other Loan Document, this
Agreement shall control. Without limiting the generality of the foregoing, no
provision of any Letter of Credit Application, Security Instrument or other
agreement or document executed in connection herewith shall give the Agent or
any Lender any rights that are greater than the rights such Persons have under
this Agreement with respect to the same subject matter.

      9.11 Governing Law. THIS AGREEMENT AND THE NOTES SHALL BE DEEMED TO BE
CONTRACTS MADE UNDER AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY
THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO PRINCIPLES THEREOF
RELATING TO CONFLICTS OF LAW.

      9.12 Jurisdiction and Venue. ALL ACTIONS OR PROCEEDINGS WITH RESPECT TO,
ARISING DIRECTLY OR INDIRECTLY IN CONNECTION WITH, OUT OF, RELATED TO, OR FROM
THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE LITIGATED, AT THE SOLE
DISCRETION AND ELECTION OF THE AGENT OR THE COLLATERAL AGENT, IN THE COURTS OF
THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN
DISTRICT OF NEW YORK. EACH BORROWER HEREBY SUBMITS TO THE NON-EXCLUSIVE
JURISDICTION OF THE AFORESAID COURTS AND HEREBY WAIVES ANY RIGHTS IT MAY HAVE TO
TRANSFER OR CHANGE THE JURISDICTION OR VENUE OF ANY LITIGATION BROUGHT AGAINST
IT BY THE AGENT, THE COLLATERAL AGENT OR ANY LENDER IN ACCORDANCE WITH THIS
SECTION.

      9.13 Appointment of Agent for Service of Process. The Borrower hereby
irrevocably designates CT Corporation System, or such other corporate process
agent as is acceptable to the Agent, as the designee, appointee and agent of the
Borrower to receive, for and on behalf of such Borrower, service of process out
of any of the aforementioned courts in any legal action or proceeding with
respect to this Agreement, any other Loan Document or any document related
thereto. It is understood that a copy of such process served on such agent will
be promptly forwarded by mail to such Borrower at its address specified below
its name on the signature pages hereof, but the failure of such Borrower to
receive such copy shall not affect in any way the service of such process. Each
Borrower further irrevocably consents to the service of process of any of the
courts mentioned in Section 9.12 in any such action or proceeding by the mailing
of copies thereof by registered or certified mail, postage prepaid, to such
Borrower at such address, such service to become effective four days after
mailing. Nothing herein shall affect the right of the Agent or any Lender to
serve process in any other manner permitted by law.


                                       76

      9.14 Waiver of Rights to Jury Trial. THE BORROWERS, THE AGENT, THE
COLLATERAL AGENT, AND EACH LENDER HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY,
IRREVOCABLY, AND UNCONDITIONALLY WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY
ACTION, SUIT, PROCEEDING, COUNTERCLAIM, OR OTHER LITIGATION THAT RELATES TO OR
ARISES OUT OF ANY OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE ACTS OR
OMISSIONS OF THE AGENT, THE COLLATERAL AGENT OR ANY LENDER IN THE ENFORCEMENT OF
ANY OF THE TERMS OR PROVISIONS OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR
OTHERWISE WITH RESPECT THERETO. THE PROVISIONS OF THIS SECTION ARE A MATERIAL
INDUCEMENT FOR THE AGENT, THE COLLATERAL AGENT AND THE LENDERS ENTERING INTO
THIS AGREEMENT.

      9.15 Integration. THIS AGREEMENT CONSTITUTES THE ENTIRE AGREEMENT AMONG
THE PARTIES HERETO WITH RESPECT TO THE SUBJECT HEREOF AND SHALL SUPERSEDE ANY
PRIOR AGREEMENT BETWEEN OR AMONG THE PARTIES, WHETHER WRITTEN OR ORAL, RELATING
TO THE SUBJECT HEREOF. FURTHERMORE, IN THIS REGARD, THIS AGREEMENT AND THE OTHER
WRITTEN LOAN DOCUMENTS REPRESENT, COLLECTIVELY, THE FINAL AGREEMENT AMONG THE
PARTIES THERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,

$_____________                                                December ___, 1998

            FOR VALUE RECEIVED and WITHOUT GRACE, the undersigned ("Maker,"
whether one or more) promises to pay to the order of __________________________

___________________________________________________________ AND __/100 DOLLARS
($_____________), or so much thereof as may be advanced and outstanding against
this Note pursuant to the First Amended and Restated Credit Agreement of even
date herewith by and among Maker, Payee, the Agent, CIBC Inc., and the lenders
signatory thereto from time to time (as amended, restated, or supplemented from
time to time, the "Credit Agreement," defined terms from which are used herein
with the meaning assigned thereto in the Credit Agreement, unless expressly
provided to the contrary herein), together with interest at the rates and
calculated as provided in the Credit Agreement. The principal and interest
hereunder shall be due and payable on the dates and in the amounts as are

Maker hereunder, the liability of all such parties for full performance under
this Note shall be joint and several.

            Reference is hereby made to the Credit Agreement for matters
governed thereby, including, without limitation, certain events which will
entitle the holder hereof to accelerate the maturity of all amounts due
hereunder.

            This Note is issued pursuant to, is a "Note" under, and is payable
as provided in the Credit Agreement. Subject to compliance with applicable
provisions of the Credit Agreement, Maker may at any time pay the full amount or
any part of this Note without the payment of any premium or fee, but such

payment as it becomes due of any payment on this Note provided for in the Credit
Agreement.

            Without being limited thereto or thereby, this Note is secured by
the Security Instruments.

            The obligations of this Note are without recourse to KCS Energy,
Inc. except as provided in Section 2.27 of the Credit Agreement.

            This Note constitutes a renewal and extension of a portion of the
Obligations of the Borrowers arising under and pursuant to that certain
promissory note dated January 2, 1997 in the original principal amount of
$150,000,000 executed by the Maker in favor of Agent in connection with the
Credit Agreement dated January 2, 1997 as amended by a First Amendment to Credit
Agreement dated March 24, 1998 and a Second Amendment to Credit Agreement dated
November
<PAGE>   94

12, 1998 by and among Maker and other Borrowers, the Agent, CIBC Inc., as
collateral agent, and the lenders signatory thereto (the "Original Credit
Agreement"). Maker acknowledges and agrees that this Note is secured by the
Security Instruments and all the other Loan Documents and all liens and security
interests created, evidenced by or recorded in any applicable jurisdiction in
connection with the Original Credit Agreement as amended and restated by the
Credit Agreement, and that such liens and security interests secure the
Obligations as set forth in the Security Instruments with the same force, effect
and priority with respect to the Credit Agreement as they had in connection with
the Original Credit Agreement.

herein shall have the meaning assigned to such term in the Credit Agreement.

            In our representation of the Borrowers, we have examined an executed
counterpart of each of the following (the "Loan Documents"):

            (1) the Credit Agreement;

            (2) the Notes; and

            (3) the Stock Pledge.

            We have also examined the originals, or copies certified to our
satisfaction, of such other records of the Borrowers, certificates of public
officials and officers of the Borrowers, agreements, instruments, and documents
as we have deemed necessary as a basis for the opinions hereinafter expressed.


                                     VIII-i
<PAGE>   117

            In making such examinations, we have, with your permission, assumed:

            a) the genuineness of all signatures to the Loan Documents other
than those of the Borrowers;

            b) the authenticity and completeness of all documents submitted to
us as originals and the conformity with the originals of all documents submitted
to us as copies;

            c) the Agent, the Collateral Agent and each Lender is authorized and
has the power to enter into and perform its obligations under the Credit
Agreement;

            d) the due authorization, execution, and delivery of all Loan
Documents by each party thereto other than the Borrowers; and

            e) the representations as to factual matters made by the Borrowers
in the Loan Documents are true and complete.

            Based upon the foregoing and subject to the qualifications set forth
herein, we are of the opinion that:

            A. Each of the Borrowers and Cal is a corporation duly organized,
legally existing, and in good standing under the laws of its state of
incorporation and is duly qualified as a foreign corporation in the
jurisdictions listed under its name on Schedule A, attached to and made a part
of this Opinion. The execution and delivery by the Borrowers and Cal of the
respective Security Instruments to which each Borrower or Cal is a party are
within the power of each Borrower and Cal and have been duly authorized by all
necessary corporate action.

            B. The execution and delivery by the Borrowers of the Credit
Agreement and the borrowings thereunder, the execution and delivery by the
Borrowers of the other Loan Documents to which each Borrower is a party, and the
payment and performance of all obligations of the Borrowers thereunder are
within the power of each Borrower, have been duly authorized by all necessary
corporate action, and do not (a) require the consent of any Governmental
Authority, (b) contravene or conflict with any Requirement of Law or the
articles or certificate of incorporation, bylaws, or other organizational or
governing documents of the Borrowers, (c) to our knowledge, contravene or
conflict with any indenture, instrument, or other agreement to which any
Borrower is a party or by which any Property of any Borrower may be presently
bound or encumbered, or (d) to our knowledge, result in or require the creation
or imposition of any Lien upon any Property of the Borrowers other than as
contemplated by the Loan Documents.

            C. The execution and delivery of the Stock Pledge and the other Loan
Documents executed by KCS and the performance of all obligations of KCS
thereunder are within the power of KCS, have been duly authorized by all
necessary corporation action, and do not, (a) require the consent of any
Governmental authority, (b) contravene or conflict with any Requirement of Law
or other articles or certificate of incorporation, bylaws, or other
organizational or governing documents of KCS, (c) to our knowledge, contravene
or conflict with any indenture, instrument, or other agreement to


                                     VIII-ii
<PAGE>   118

which KCS is a party or by which any Property of KCS may be presently bound or
encumbered, or (d) to our knowledge, result in or require the creation or
imposition of any Lien upon any Property of KCS other than as contemplated by
the Loan Documents.

            D. The Credit Agreement, the Notes and the other Loan Documents
which are governed by New York law to which each Borrower is a party constitute
legal, valid, and binding obligations of such Borrower, enforceable against such
Borrower in accordance with their respective terms.

            E. To our knowledge, except as disclosed in Exhibit X to the Credit
Agreement, no litigation or other action of any nature affecting the Borrowers
is pending before any Governmental Authority or threatened against the
Borrowers, which, if determined adversely to such Borrower, could reasonably be
expected to have a Material Adverse Effect or affect any Borrower's ability to
execute, deliver or perform in any material respect its obligations under the
Loan Documents.

            F. No authorization, consent, approval, exemption, franchise, permit
or license of, or filing (other than filing of Security Instruments in
appropriate filing offices) with, any Governmental Authority or any other Person
is required to authorize or is otherwise required in connection with the valid
execution and delivery by the Borrowers of those Loan Documents which are
governed by New York Law, or the payment or performance by the Borrowers of the
Obligations arising pursuant to those Loan Documents entered into at Closing
which are governed by New York law.

            G. No transaction contemplated by the Loan Documents is in violation
of any regulations promulgated by the Board of Governors of the Federal Reserve
System, including, without limitation, Regulations G, T, U, or X.

            H. No Borrower is, nor is any Borrower directly or indirectly
controlled by or acting on behalf of any Person which is, an "investment
company" or an "affiliated person" of an "investment company" within the meaning
of the Investment Company Act of 1940, as amended.

            I. No Borrower is a "holding company," or an "affiliate" of a
"holding company" or of a "subsidiary company" of a "holding company," within
the meaning of the Public Utility Holding Company Act of 1935, as amended.

            The opinions expressed herein are subject to the following
qualifications and limitations:

            We are licensed to practice law only in the States of New Jersey and
New York and other jurisdictions whose laws are not applicable to the opinions
expressed herein; accordingly, the foregoing opinions are limited solely to the
laws of the State of New Jersey, the State of New York, applicable United States
federal law, and the corporation laws of the State of Delaware.

            The validity, binding effect, and enforceability of the Loan
Documents or certain provisions thereof may be limited or affected by
bankruptcy, insolvency, moratorium, fraudulent conveyance, reorganization, or
other similar laws affecting rights of creditors generally, including, without
limitation, judicial decisions, statutes or rules of law which limit the effect
of waivers of rights


                                    VIII-iii
<PAGE>   119

by a debtor or guarantor and limit the permissible scope of indemnification
agreements, provided, however, that the limitations and other effects of such
statutes or rules of law, as currently in effect, upon the validity and binding
effect of the Loan Documents should not differ materially from the limitations
and other effects of such statutes or rules of law upon the validity and binding
effect of credit agreements, promissory notes, stock pledge agreements and
guaranties generally. No opinion is expressed with respect to the enforceability
of any provisions that may purport to bind the Borrowers to the waiver of any
right or defense which by virtue of applicable law or equitable principle cannot
be waived.

            The enforceability of the respective obligations of the Borrowers
under the Loan Documents is subject to general principles of equity (whether
such enforceability is considered in a suit in equity or at law).

            Whenever our opinion is modified by the phrase "to our knowledge",
to the extent that it relates to KCS and KCS Energy Services, our opinion is
based solely upon information which we have obtained in the course of our
representation of the Borrowers in matters to which we have devoted substantive
attention, without any further investigation or inquiry.

            This Opinion is furnished by us solely for the benefit of the Agent,
the Collateral Agent and the Lenders in connection with the transactions
contemplated by the Loan Documents and is not to be quoted in whole or in part
or otherwise referred to or disclosed in any other transaction.

            This Opinion speaks as of the date hereof, and we disclaim any
obligation to update this opinion to you.

                                      Very truly yours,

the meaning specified in the Ratification.

      (a) Each of the Ratification, the Credit Agreement, the Notes and other

Ratification and the instruments referenced therein have been duly authorized;

                                     OPINION

      Based solely upon the foregoing and subject to the comments,
qualifications and other matters set forth herein, it is our opinion that:

      1. The Ratification constitutes legal, valid and binding obligations of
the Mortgagor, enforceable against the Mortgagor in accordance with its terms.

      2. The Ratification is in form sufficient to amend the Mortgages (as such
term is defined in the Ratification by reference to Schedule I of the
Ratification ("Schedule I")), and to renew, extend and carry forward the liens
and security interests arising under such Mortgages (the "Liens") in the
Mortgaged Property described therein in favor of the Collateral Agent.

      3. The Ratification is in proper form for recording in the real property
records maintained by the Clerk or Recorder of the applicable counties
identified on Schedule I.

      4. Upon recordation and filing of the Ratification in the applicable
counties where Mortgages have been recorded and filed as set forth in Schedule I
to the Ratification, the Ratification will (i) amend the Mortgages; and (ii)
renew, extend and carry forward the Liens in favor of the Collateral Agent
created under the Mortgages to secure the Notes and all other indebtedness
described in the Ratification.

      5. The recording of the Ratification in each office of each county in the
State of ___________ in which the Mortgages were recorded are the only
recordings in the State of ___________ necessary in connection with the
renewing, extending and carrying forward of the Liens and other rights created
under the Mortgages. No other documents or instruments need be recorded or filed
in any public office in the State of ___________ for the validity and
enforceability of the Mortgages (as amended by the Ratification) or to permit
the Collateral Agent to enforce in the State of _____________ its rights under
the Mortgages as amended by the Ratification.

      6. No consent of or filing with any governmental authority or agency of
the State of ___________ or any county therein is required in connection with
the execution and delivery of the Ratification by the Mortgagor.

      7. The execution, delivery and filing of the Loan Documents will not
conflict with any regulation, existing law, or any rule of any state regulatory
body, administration, agency or other governmental body in the State of
____________________.

      8. No state or local transfer tax, stamp tax or other fee, tax or
governmental charge (other than filing and recording fees imposed by law) is
