                               CERTAIN DEFINITIONS

The following are definitions of terms commonly used in the oil and natural gas
industry and this document.

Unless otherwise indicated in this document, natural gas volumes are stated at
the legal pressure base of the state or area in which the reserves are located
at 60 (degrees) Fahrenheit. Natural gas equivalents are determined using the
ratio of six Mcf of natural gas to one barrel of crude oil, condensate or
natural gas liquids so that one barrel of oil is referred to as six Mcf of
natural gas equivalent or "Mcfe." As used in this document, the following terms
have the following specific meanings: "Mcf" means thousand cubic feet, "MMcf""
means million cubic feet, "Bcf" means billion cubic feet, "Bbl" means barrel,
"MBbl" means thousand barrels, "Mcfe" means thousand cubic feet equivalent,
"Bcfe" means billion cubic feet equivalent, "MMcfe" means million cubic feet
equivalent, and "MMBtu" means million British thermal units.

AVERAGE FINDING COST. The average amount of total capital expenditures,
including acquisition costs, and exploration and abandonment costs, for oil and
natural gas activities divided by the amount of proved reserves added in the
specified period.

CAPITAL EXPENDITURES. Costs associated with exploratory and development drilling
(including exploratory dry holes); leasehold acquisitions; seismic data
acquisitions; geological, geophysical and land related overhead expenditures;
delay rentals; producing property acquisitions; other miscellaneous capital
expenditures; compression equipment and pipeline costs.

DEVELOPED ACREAGE. The number of acres which are allocated or assignable to
producing wells or wells capable of production.

DEVELOPMENT WELL. A well drilled within the proved area of an oil or natural gas
reservoir to the depth of a stratigraphic horizon known to be productive.

EXPLORATORY WELL. A well drilled to find and produce oil or natural gas in an
unproved area, to find a new reservoir in a field previously found to be
productive of oil or natural gas in another reservoir, or to extend a known
reservoir.

GROSS ACRES OR GROSS WELLS. The total acres or wells, as the case may be, in
which the Company has a working interest.

LOE. Lease operating expenses, which includes, among other things, extraction
costs and production and property taxes.

OPERATOR. The individual or company responsible to the working interest owners
for the exploration, development and production of an oil or natural gas well or
lease.

PRESENT VALUE OF FUTURE NET REVENUES OR PV-10. The present value of estimated
future net revenues to be generated from the production of proved reserves, net
of estimated production and ad valorem taxes, future capital costs and operating
expenses, using prices and costs in effect as of the date indicated, without
giving effect to federal income taxes. The future net revenues have been
discounted at an annual rate of 10% to determine their "present value." The
present value is shown to indicate the effect of time on the value of the
revenue stream and should not be construed as being the fair market value of the
properties.

RECOMPLETION. The completion of an existing well for production from a formation
that exists behind the casing of the well.

RESERVES. Natural gas and crude oil, condensate and natural gas liquids on a net
revenue interest basis, found to be commercially recoverable. "Proved developed
reserves" includes proved developed producing reserves and proved developed
behind-pipe reserves. "Proved developed producing reserves" includes only those
reserves expected to be recovered from existing completion intervals in existing
wells. "Proved undeveloped reserves" includes those reserves expected to be
recovered from new wells on proved undrilled acreage or from existing wells
where a relatively major expenditure is required for recompletion.

UNDEVELOPED ACREAGE. Lease acres on which wells have not been drilled or
completed to a point that would permit the production of commercial quantities
of oil and natural gas regardless of whether or not such acreage contains proved
reserves.

WORKING INTEREST. An interest in an oil and natural gas lease that gives the
owner of the interest the right to drill and produce oil and natural gas on the
leased acreage and requires the owner to pay a share of the costs of drilling
and production operations. The share of production to which a working interest
owner is entitled will always be smaller than the share of costs that the
working interest owner is required to bear, with the balance of the production
accruing to the owners of royalties.

ITEM 1.   BUSINESS

GENERAL

     Evergreen Resources, Inc. ("Evergreen" or "the Company"), is a Colorado
corporation organized on January 14, 1981. Evergreen is an independent energy
company engaged in the exploration, development, production, operation and
acquisition of oil and gas properties. Evergreen's primary focus is on
developing and expanding its coalbed methane properties located on approximately
200,000 gross acres in the Raton Basin in southern Colorado. Evergreen also
holds exploration licenses on approximately 513,000 acres onshore in the United
Kingdom, and an oil and gas exploration contract on approximately 2.4 million
acres in northern Chile.

     Evergreen maintains its principal executive offices at Suite 1200, 1401
17th Street, Denver, Colorado 80202, and its telephone number is (303) 298-8100.

     The authorized capitalization of the Company is 50,000,000 shares of no par
value common stock, of which 11,142,613 shares were issued and outstanding at
December 31, 1998, and 25,000,000 shares of $1.00 par value preferred stock,
none of which were issued and outstanding at December 31, 1998.

     This report on Form 10-K contains 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"), including statements regarding, among other items,
(i) the Company's growth strategies, (ii) anticipated trends in the Company's
business and its future results of operations, (iii) market conditions in the
oil and gas industry, (iv) the ability of the Company to make and integrate
acquisitions and (v) the outcome of litigation and the impact of governmental
regulation. These forward-looking statements are based largely on the Company's
expectations and are subject to a number of risks and uncertainties, many of
which are beyond the Company's control. Actual results could differ materially
from those implied by these forward-looking statements as a result of, among
other things, a decline in natural gas production, a decline in natural gas
prices, incorrect estimations of required capital expenditures, increases in the
cost of drilling, completion and gas gathering, an increase in the cost of
production and operations, an inability to meet growth projections, and/or
changes in general economic conditions. Actual results could materially differ
and could be adversely affected by the information set forth under the headings
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business and Properties." In light of these risks and
uncertainties, there can be no assurance that actual results will be as
projected in the forward-looking statements.

     For a discussion of the development of the Company's business, see Item 2.

FOCUS - RATON BASIN

     The Company's current operations are principally focused on developing and
expanding its coalbed methane project located in the Raton Basin in southern
Colorado.

     Evergreen is one of the largest holders of oil and gas leases in the Raton
Basin with approximately 200,000 gross acres. In addition, the Company's daily
gas sales represent approximately 70% of the gas currently sold from the Raton
Basin. Evergreen currently has 173 net producing gas wells on its Raton Basin
properties and four exploratory wells which are subject to further evaluation.
The Company has identified approximately 800 drilling locations on its Raton
Basin acreage, of which 343 were included in the Company's proved reserve base
at December 31, 1998. These proven locations comprise approximately 43% of the
Company's total acreage in the Raton Basin. Evergreen intends to spend
approximately $35 million over the next year on the further development of the
Raton Basin, including drilling approximately 80 wells and expanding and
upgrading its gathering and compression facilities.

     At December 31, 1998, Evergreen had estimated net proved reserves of 405
Bcfe with a PV-10, before future income tax expense of approximately $215
million. Natural gas constituted all of Evergreen's estimated net proved
reserves, all of which were located in the Raton Basin and 60% of which were
developed. Evergreen has a 100% working interest in the majority of its Raton
Basin acreage and wells, and also owns the gathering systems and related
equipment associated with these wells. The Company acts as operator for all of
its Raton Basin properties.

                                       4
<PAGE>

     Since the completion of a pipeline from the Raton Basin and the
corresponding commencement of Company gas sales in early 1995, the Company has
achieved substantial growth in reserves and production. Evergreen's estimated
net proved reserves have increased from approximately 63 Bcfe at March 31, 1995
to 405 Bcfe at December 31, 1998. Over this period, the number of producing
wells and average gross daily production increased from 9 wells and 1.5 MMcf to
173 wells and 43 MMcf, respectively. Since inception of the Company's drilling
efforts in the Raton Basin, the Company has drilled and tested a total of 130
producing wells and achieved a 98% success rate. An additional 43 wells were
acquired through property acquisitions in 1998 for a total of 173 producing
wells.

     Evergreen believes that it has gained significant experience in coalbed
methane exploration and development, including the utilization of enhanced
drilling, completion and production techniques developed over a number of years.
This experience has enabled the Company to increase per well production and to
achieve low finding and development costs. From inception of its Raton Basin
project through December 31, 1998, the Company spent approximately $93 million
on the drilling and completion of its wells, pipelines, gathering systems,
compression equipment and the acquisition of additional working interests, which
represents a total finding and development cost of $0.22 per Mcfe.

     In addition, the Company's lease operating expenses ("LOE") and general and
administrative costs per Mcfe have declined steadily since Raton Basin gas sales
began in early 1995. For the year ended December 31, 1995, Evergreen's lease
operating expenses and general and administrative costs were $0.88 per Mcfe and
$0.94 per Mcfe, respectively, as compared to $0.34 per Mcfe and $0.19 per Mcfe,
respectively, for the year ended December 31, 1998.

     The Raton Basin is an onshore depositional and structural basin that is
approximately 80 miles long and 50 miles wide, located in southern Colorado and
northern New Mexico. The Raton Basin contains two coal bearing formations, the
Vermejo formation coals located at depths of between 450 and 3,500 feet and the
shallower Raton formation coals, located at depths from the surface to
approximately 2,000 feet. To date, Evergreen's production has been from the
Vermejo formation coals; however, Evergreen believes that the Raton formation
coal seams may be profitably exploited as well.

     Approximately 133,900 acres of the Company's 200,000 gross acres in the
Raton Basin have been included in three federal units, which simplifies lease
maintenance for the Company. Formation of these federal units allows Evergreen,
as unit operator, to base development decisions within the unit on technical,
geologic and geophysical data, rather than on the fulfillment of lease term
obligations.

INTERNATIONAL PROJECTS

     UNITED KINGDOM. Evergreen holds licenses on approximately 513,000 acres
onshore in the United Kingdom. The Company believes that there are potential
opportunities to develop coalbed methane reserves within these license areas. To
date, Evergreen has spent approximately $8.5 million on this project and is
holding discussions with potential industry partners for the purpose of further
evaluating and developing the licensed areas. Evergreen will spend approximately
$3 million in 1999 to drill gob gas wells and maintain the licenses.

     The Company has recently completed a 3D seismic program in the United
Kingdom in an area in which Evergreen plans to drill a multi-well pilot coalbed
methane project. Evergreen is holding discussions with potential industry
partners for the purpose of evaluating and developing the Current Licenses and
will not start the pilot program until a partner has been secured. The
Company has recently purchased a drilling rig for this project. This rig
initially will be tested in the Raton Basin in early March and shipped to the
United Kingdom for the drilling of the seven wells in the second half of 1999.

     FALKLAND ISLANDS. The Falkland Islands consortium, in which Evergreen has a
net 2% interest, has completed operations on the second well (and the industry's
fifth well) in the North Falklands Basin. Well 14/9-2 was spudded on October 13,
1998, and finished drilling on October 28, 1998. It reached a total depth of
approximately 8,000 feet and was plugged and abandoned as a dry hole with oil
shows.

     CHILE. In March 1997, the Government of Chile awarded an oil and gas
exploration license to Evergreen on two 5,000 square kilometer (approximately
1.2 million acre) blocks in northern Chile. Evergreen has a 75% working interest
in the blocks and will serve as operator. Empresa Nacional del Petroleo
("ENAP"), the Chilean-owned energy

                                       5
<PAGE>

company, holds the remaining 25% working interest. Evergreen expects to engage
in surface, geologic mapping, ground based magnetic and gravity surveys and
conduct a proprietary 2D seismic program over the next two years at an aggregate
cost to the Company of approximately $2.2 million.

BUSINESS STRATEGY

     Evergreen's objective is to increase reserves, production, cash flow,
earnings and net asset value per share. To accomplish this objective, Evergreen
intends to utilize its competitive strengths, which include (i) its experience
and operating expertise in coalbed methane properties, (ii) its significant
acreage position in the Raton Basin, (iii) its position as a low-cost finder,
developer and producer of natural gas and (iv) the potential of its
international projects.

     In order to implement its strategy, Evergreen will seek to:

  -  ACCELERATE DEVELOPMENT OF THE RATON BASIN. Since commencement of the
     Company's drilling program in 1993, the Company has drilled a total of 152
     wells in the Raton Basin. Of this total, 130 are currently in production,
     and 4 are exploratory and subject to further evaluation. The Company plans
     to drill approximately 80 wells in 1999. During 2000, the Company plans to
     drill approximately 80 wells and expand its gathering and compression
     facilities. The Company's capital budget for the 1999 drilling and
     expansion program is approximately $35 million. The expansion program will
     be funded by cash flow from operations and available borrowings under the
     Company's $75 million credit facility.

  -  MAINTAIN CONTROL OF OPERATIONS. The Company acts as operator for all of its
     producing properties within the Raton Basin and controls all phases of
     drilling, completion and well stimulation. The Company also constructs and
     operates all of its gas gathering systems, which have been specifically
     designed to optimize production from coalbed methane wells. By operating
     its producing properties, Evergreen believes it has greater control over
     its expenses and the timing of exploration and development of such
     properties. The Company is also the designated operator for its United
     Kingdom and Chilean projects.

  -  IMPROVE AND EXPAND GAS MARKETING CAPABILITIES IN THE RATON BASIN.
     Evergreen's natural gas sales from the Raton Basin commenced upon the
     completion of a pipeline system in January 1995, which connected the
     Company's gathering system to the Colorado Interstate Gas Co. ("CIG")
     pipelines. In early September 1998, CIG completed the Campo Lateral
     expansion project. The expansion significantly lowers pipeline pressures
     and increases initial pipeline capacity from the Raton Basin to 100 MMcf of
     gas per day, up from 47 MMcf per day.

  -  PURSUE INTERNATIONAL OPPORTUNITIES. The Company seeks to identify
     attractive international oil and gas projects that require relatively small
     capital investments but which have potential for favorable returns. Since
     1992, the Company has obtained onshore exploration licenses covering
     approximately 513,000 acres in the United Kingdom and an oil and gas
     exploration license on approximately 2.4 million acres in northern Chile.
     The Company expects to spend approximately $3 million in 1999 for the
     development of its international projects. Evergreen will seek additional
     partners to help minimize the Company's upfront capital requirements and
     other costs associated with development of these projects.

  -  ACQUIRE ADDITIONAL PROPERTY INTERESTS. In 1998 and 1996, the Company
     acquired additional property interests in the Raton Basin totaling
     approximately 97 Bcf of estimated proved reserves at an average acquisition
     cost of $0.34 per Mcf. The Company expects that it will continue to
     evaluate and make acquisitions of oil and gas properties located in its
     principal areas of operation and in other areas that provide attractive
     investment opportunities, particularly where the Company can add value
     through its technical expertise.

CUSTOMERS AND MARKETS

     GAS MARKETING. Primero Gas Marketing Company ("Primero") is a wholly-owned
subsidiary of the Company that was formed to market and sell natural gas for the
Company and third parties. To date, Primero has only marketed and sold gas on
behalf of the Company and working interest partners. Primero also operates the
Company's gathering system and purchases all the Company's production from its
Raton Basin wells.

     The expanding production in the Raton Basin led CIG to file with the
Federal Energy Regulatory Commission (the "FERC") for approval to construct a
new, 115-mile, 16-inch pipeline connecting CIG's Picketwire Lateral pipeline
near Trinidad, Colorado to its mainline compressor station at Campo, Colorado
(the "Campo Lateral"). Now completed, the Campo Lateral has initial capacity of
up to approximately 100 MMcf per day, which more than doubles the pipeline
capacity previously available from the Raton Basin. The pipeline capacity may be
further expanded through the use of additional compression facilities. In August
1997, the Company entered into a new agreement with CIG having a term of 15
years which entitles the Company to firm transportation of its Raton Basin gas
through the Campo Lateral. The Company committed to transport natural gas from
the Raton Basin through this new pipeline commencing in September 1998. The
initial commitment was 25 MMcf per day, increasing every six months to 41 MMcf
per day, 18 months after the commencement. In 1998, the Company acquired certain
properties in the Raton Basin and additionally assumed firm transportation
commitment of 12 MMcf per day. As of March 1, 1999, the Company has total firm
commitments of 42 MMcf per day. Subject to available capacity in the pipeline,
the Company has the first right to increase its volumes up to 100 MMcf per day.
Evergreen believes that the CIG agreement will expand the range of customers to
which it can market its gas, thereby potentially increasing the prices Evergreen
will receive for its gas. The CIG contract provides for delivery of the
Company's gas into interstate pipelines in Texas, from which it can be
transported to Midwest and East Coast markets. Absent the Campo Lateral, the
Company would be restricted in the total production that could be transported
from the Raton Basin.

     MAJOR CUSTOMERS. Evergreen has two major customers Aquila Energy
Corporation and Natural Gas Transmission Services, Inc., which purchased
approximately 45%, and 44%, respectively, of the Company's gas production for
the year ended December 31, 1998. Based on the general demand for gas, the loss
of either or both of these customers would not be expected to have a material
adverse effect on Evergreen's business. None of the Company's existing marketing
agreements obligates the Company to continue sales to any particular gas
purchaser for a period longer than 12 months. As the Company's base of
production grows in the Raton Basin, the Company hopes to be able to enter into
long-term contracts with end users at favorable prices. Currently, the Company's
gas is sold at spot market prices or under contracts for terms of one year or
less.

COMPETITION

     The Company competes with numerous other companies in virtually all facets
of its business, including many that have significantly greater resources. Such
competitors may be able to pay more for desirable leases and to evaluate, bid
for and purchase a greater number of properties than the financial or personnel
resources of the Company permit. The ability of the Company to increase reserves
in the future will be dependent on its ability to select and acquire suitable
producing properties and prospects for future exploration and development. The
availability of a market for oil and natural gas production depends upon
numerous factors beyond the control of producers, including but not limited to
the availability of other domestic or imported production, the locations and
capacity of pipelines, and the effect of federal and state regulation on such
production.

GOVERNMENT REGULATION OF THE OIL AND GAS INDUSTRY

     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 restrictive effect on the Company's
method of operations than on other similar companies in the energy industry.

                                       7

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

     FEDERAL REGULATION OF THE SALE AND TRANSPORTATION OF OIL AND GAS. Various
aspects of the Company's oil and natural gas operations are regulated by
agencies of the Federal government. The FERC regulates the transportation and
sale for resale of natural gas in interstate commerce pursuant to the Natural
Gas Act of 1938 ("NGA") and the Natural Gas Policy Act of 1978 ("NGPA"). In the
past, the Federal government has regulated the prices at which oil and gas could
be sold. While "first sales" by producers of natural gas, and all sales of crude
oil, condensate and natural gas liquids can currently be made at uncontrolled
market prices, Congress could reenact price controls in the future. Deregulation
of wellhead sales in the natural gas industry began with the enactment of the
NGPA in 1978. In 1989, Congress enacted the Natural Gas Wellhead Decontrol Act
(the "Decontrol Act"). The Decontrol Act removed all NGA and NGPA price and
nonprice controls affecting wellhead sales of natural gas effective January 1,
1993.

     Commencing in April 1992, the FERC issued Order Nos. 636, 636-A, 636-B and
636-C ("Order No. 636"), which require interstate pipelines to provide
transportation services separate, or "unbundled," from the pipelines' sales of
gas. Also, Order No. 636 requires pipelines to provide open access
transportation on a nondiscriminatory basis that is equal for all natural gas
shippers. Although Order No. 636 does not directly regulate the Company's
production activities, the FERC has stated that it intends for Order No. 636 to
foster increased competition within all phases of the natural gas industry. It
is unclear what impact, if any, increased competition within the natural gas
industry under Order No. 636 will have on the Company's activities. Although
Order No. 636, assuming it is upheld in its entirety, could provide the Company
with additional market access and more fairly applied transportation service
rates, Order No. 636 could also subject the Company to more restrictive pipeline
imbalance tolerances and greater penalties for violation of those tolerances.
Order No. 636 and subsequent FERC orders issued in individual pipeline
restructuring proceedings have been the subject of appeals, the results of which
have generally supported the FERC's open-access policy. In 1997, the United
States Court of Appeals for the District of Columbia Circuit largely upheld
Order No. 636. Because further review of certain of these orders is still
possible and other appeals remain pending, it is difficult to predict the
ultimate impact of the orders on the Company and its production efforts.

     The FERC has announced several important transportation-related policy
statements and proposed rule changes on matters relevant to the Company's
business, including the appropriate manner in which interstate pipelines release
capacity under Order No. 636 and, more recently, the price which shippers can
charge for their released capacity. In addition, in 1995, the FERC issued a
policy statement on how interstate natural gas pipelines can recover the costs
of new pipeline facilities. In January 1996, the FERC issued a policy statement
and a request for comments concerning alternatives to its traditional
cost-of-service rate making methodology. A number of pipelines have obtained
FERC authorization to charge negotiated rates as one such alternative. In
February 1997, the FERC announced a broad inquiry into issues facing the natural
gas industry to assist the FERC in establishing regulatory goals and priorities
in the post-Order No. 636 environment. While these changes would affect the
Company only indirectly, they are intended to further enhance competition in the
natural gas markets. The Company cannot predict what action the FERC will take
on these matters, nor can it predict whether the FERC's actions will achieve its
stated goal of increasing competition in natural gas markets. However, the
Company does not believe that it will be treated materially differently than
other natural gas producers and markets with which it competes.

     Commencing in October 1993, the FERC issued a series of rules (Order Nos.
561 and 561-A) establishing an indexing system under which oil pipelines will be
able to change their transportation rates, subject to prescribed ceiling levels.
The indexing system, which allows or may require pipelines to make rate changes
to track changes in the Producer Price Index for Finished Goods, minus one
percent, became effective January 1, 1995. The Company is not able at this time
to predict the effects of Order Nos. 561 and 561-A, if any, on the
transportation costs associated with oil production. The effects, if any, of
these policies on the Company's operations are uncertain.

     The FERC has also recently issued numerous orders confirming the sale and
abandonment of natural gas gathering facilities previously owned by interstate
pipelines and acknowledging that if the FERC does not have jurisdiction over
services provided thereon, then such facilities and services 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 adequacy of existing laws
affecting gathering rates and/or services. Other state regulation of gathering
facilities generally includes various safety, environmental, and in some
circumstances, nondiscriminatory take requirements, but

                                       8
<PAGE>

does not generally entail rate regulation. Thus, natural gas gathering may
receive greater regulatory scrutiny of state agencies in the future. The
Company's gathering operations could be adversely affected should they be
subject in the future to increased state regulation of rates or services,
although the Company does not believe that it would be affected by such
regulation any differently than other natural gas producers or gatherers. In
addition, the FERC's approval of transfers of previously-regulated gathering
systems to independent or pipeline affiliated gathering companies that are not
subject to FERC regulation may affect competition for gathering or natural gas
marketing services in areas served by those systems and thus may affect both the
costs and the nature of gathering services that will be available to interested
producers or shippers in the future.

     The Company owns certain natural gas pipeline facilities that it believes
meet the traditional tests the FERC has used to establish a pipeline's status as
a gatherer not subject to the FERC jurisdiction. Whether on state or federal
land or in offshore waters subject to the Outer Continental Shelf Land Act
("OCSLA"), natural gas gathering may receive greater regulatory scrutiny in the
post-Order No. 636 environment.

     The Company conducts certain operations on federal oil and gas leases,
which are administered by the Minerals Management Service (the "MMS"). 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
of 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 market value, establish a new MMS form for collecting value
differential data, and amend the valuation procedure for the sale of federal
royalty oil. Similar rulemaking regarding natural gas royalties has also been
considered by the agency, but there is no current proposed rule on this issue
for natural gas. The Company cannot predict what action the MMS will take on
this matter, nor can it predict at this stage of the rulemaking proceeding how
the Company might be affected by this amendment to the MMS' regulations.

     Additional proposals and proceedings that might affect the oil and gas
industry are pending before Congress, the FERC, the MMS, state commissions and
the courts. The Company cannot predict when or whether any such proposals may
become effective. In the past, the natural gas industry has been heavily
regulated. There is no assurance that the regulatory approach currently pursued
by various agencies will continue indefinitely. Notwithstanding the foregoing,
the Company does not anticipate 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 or its subsidiaries. No material portion of Evergreen's business is
subject to re-negotiation of profits or termination of contracts or subcontracts
at the election of the Federal government.

     STATE REGULATION - UNITED STATES. The Company's operations are also subject
to regulation at the state level. Such regulation includes requiring permits for
the drilling of wells, maintaining bonding requirements in order 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
conservation laws and regulations. These include the size of drilling and
spacing units or proration units and the density of wells which may be drilled
and the unitization or pooling of oil and gas properties. In addition, state
conservation laws establish maximum rates of production from oil and gas wells,
generally prohibit the venting or flaring of gas and impose certain requirements
regarding the ratability of production. State regulation of gathering facilities
generally includes various safety, environmental, and in some circumstances,
nondiscriminatory take requirements, but does not generally entail rate
regulation. These regulatory burdens may affect profitability, and the Company
is unable to predict the future cost or impact of complying with such
regulations.

     ENVIRONMENTAL MATTERS. Extensive federal, state and local laws affecting
oil and natural gas operations, including those carried on by the Company,
regulate the discharge of materials into the environment or otherwise protect
the environment. Numerous governmental agencies issue rules and regulations to
implement and enforce such laws which are often difficult and costly to comply
with and which carry substantial penalties for failure to comply. Some laws,
rules and regulations relating to the protection of the environment may, in
certain circumstances, impose "strict liability" for environmental
contamination, rendering a person liable for environmental damages, cleanup
costs and, in the case of oil spills in certain states, consequential damages
without regard to negligence or fault on the part of such person. Other laws,
rules and regulations may restrict the rate of oil and natural gas production
below the rate that would otherwise exist or even prohibit exploration or
production activities in environmentally sensitive areas. In

                                       9
<PAGE>

addition, state laws often require some form of remedial action to prevent
pollution from former operations, such as closure of inactive pits and plugging
of abandoned wells. Legislation has been and continues to be proposed in
Congress from time to time that would reclassify certain exempt oil and gas
exploration and production wastes as "hazardous wastes." This reclassification
which would make such wastes subject to much more stringent handling, disposal
and clean-up requirements. If such legislation were to be enacted, it could have
a significant impact on the operating costs of the Company, as well as the oil
and gas industry in general. Initiatives to further regulate the disposal of oil
and gas wastes are also pending in certain states and may include initiatives at
county, municipal and local government levels. These various initiatives could
have a similar impact on the Company. The regulatory burden on the oil and
natural gas industry increases its cost of doing business and consequently
affects its profitability.

     Compliance with these environmental requirements, including financial
assurance requirements and the costs associated with the cleanup of any spill,
could have a material adverse effect upon the capital expenditures, earnings or
competitive position of the Company and its subsidiaries. The Company believes
that it is in substantial compliance with current applicable environmental laws
and regulations and that continued compliance with existing requirements will
not have a material adverse impact on the Company. Nevertheless, changes in
environmental law have the potential to adversely affect the Company's
operations. For example, the U.S. Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA"), also known as the "Superfund" law,
imposes liability, without regard to fault or the legality of the original
conduct, on certain classes of persons with respect to 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 found at
the site. Persons who are or were responsible for releases of hazardous
substances under CERCLA may be subject to joint and several liability for the
costs of cleaning up the hazardous substances that have been released into the
environment and for damages to natural resources, and it is not uncommon for
neighboring landowners and other third parties to file claims for personal
injury or property damages allegedly caused by the hazardous substances released
into the environment. Under CERCLA, certain oil and gas materials and products
are, by definition, excluded from the term "hazardous substances." At least two
federal courts have recently held that certain wastes associated with the
production of crude oil may be classified as hazardous substances under CERCLA.
Similarly, under the federal Resource, Conservation and Recovery Act ("RCRA")
certain oil and gas materials and wastes are exempt from the definition of
"hazardous wastes." This exemption continues to be subject to judicial
interpretation and increasingly stringent state regulation. During the normal
course of its operations, the Company generates or has generated in the past
exempt and non-exempt wastes, including hazardous wastes, that are subject to
the RCRA and comparable state statutes. The U.S. Environmental Protection Agency
("EPA") and various state agencies continue to promulgate regulations that limit
the disposal and permitting options for certain hazardous and non-hazardous
wastes.

     The Company currently owns or leases, and has in the past owned or 
leased, several properties that for many years have been used to store and 
maintain equipment that was regularly used to explore for and produce oil and 
gas. In particular, current and prior operations of the Company included oil 
and gas production in the Rocky Mountain states and the portion of the 
Permian Basin within the State of New Mexico. Although the Company utilized 
operating and disposal practices that were standard for the industry at the 
time, hydrocarbons, materials or other wastes may have been disposed of or 
released on or under the properties owned or leased by the Company or on or 
under other locations where such wastes have been taken for disposal. In 
addition, many of these properties have from time to time been operated by 
third parties whose treatment and disposal or release of hydrocarbons or 
other wastes was not under the Company's control. These properties and the 
waste disposed thereon may be subject to CERCLA, RCRA, and analogous state 
laws. Under such laws, the Company could be required to remove or remediate 
previously disposed wastes (including wastes disposed of or released by prior 
owners or operators) or property contamination (including groundwater 
contamination).

     In connection with its coalbed methane gas production, the Company from
time to time conducts production enhancement techniques, including various
activities designed to fracture the coalbed formation. While production
enhancement techniques are performed by the Company in substantial compliance
with the requirements set forth by the State of Colorado, neither Colorado nor
the EPA regulates this coalbed formation fracturing as a form of underground
injection. On August 7, 1997, the U.S. Court of Appeals for the Eleventh Circuit
held, in a case brought by a citizens environmental organization, that hydraulic
fracturing performed in coalbed methane gas production in Alabama falls within
the definition of "underground injection" as defined in the federal Safe
Drinking Water Act and, therefore, EPA is required to regulate this activity. As
a consequence of this holding, the Eleventh Circuit also granted a petition
filed by the plaintiff in the case to review EPA's refusal to initiate
proceedings that would withdraw federal


                                       10
<PAGE>

approval of Alabama's Underground Injection Control program. It is not known 
whether EPA will apply the court's ruling in this decision outside of the 
Eleventh Circuit (Alabama, Georgia, and Florida). Nevertheless, it is 
possible that hydraulic fracturing of coalbeds for methane gas production 
will become regulated within the United States as a form of underground 
injection, resulting in the imposition of stricter performance standards 
(which, if not met, could result in diminished opportunities for methane gas 
production enhancement) and increased administrative and operating costs for 
the Company. Management of the Company cannot predict at this time whether 
regulation of hydraulic fracturing as a form of underground injection will 
have an adverse material effect on the Company's operations or financial 
position. However, such regulation is not expected to be any more burdensome 
to the Company than it would be to other similarly situated companies 
involved in coalbed methane gas production or tight gas sands production 
within the United States.

     Also in connection with its coalbed methane gas production, the Company 
may produce naturally occurring groundwater as a by-product of the production 
of methane gas. This produced groundwater is either reinjected into the 
subsurface or stored or disposed of in evaporation ponds or natural 
collection features located on the surface at or near the wellsite pursuant 
to federal, state and local statutes and regulations. In some cases, the 
produced groundwater is used for stock watering, agricultural or dust 
suppression purposes, also pursuant to federal, state and local regulation. 
The legal and regulatory classification of this produced groundwater remains 
unclear under the environmental laws discussed above as well as under the 
federal Clean Water Act ("CWA"), a strict liability statute, which governs 
the permitted and unpermitted discharge of "pollutants" to "waters of the 
United States." Under the CWA and various other state regulations, EPA, the 
State of Colorado Department of Public Health and the Environment and the 
Colorado Oil and Gas Conservation Commission each continue to assert 
administrative and regulatory enforcement authority over the storage and 
disposal of such produced groundwater. These agencies' classification or 
characterization of either: (1) such produced groundwater as a "pollutant," 
or (2) the storage, use and disposal of such water on the surface as a 
"discharge to waters of the United States" could have a significant impact on 
the regulatory treatment of this groundwater management practice and 
Evergreen's understanding of its past compliance in connection with the CWA.

     Although the Company maintains insurance against some, but not all, of the
risks described above, including insuring the costs of clean-up operations,
public liability and physical damage, there is no assurance that such insurance
will be adequate to cover all such costs, that such insurance will continue to
be available in the future or that such insurance will be available at premium
levels that justify its purchase. The occurrence of a significant event not
fully insured or indemnified against could have a material adverse effect on the
Company's financial condition and operations.

     At this time, the Company has no plans to make any material capital
expenditures for environmental control facilities. See Item 3- Legal Proceedings
regarding Southern Colorado C.U.R.E. v. Evergreen Operating Corporation.

TITLE TO PROPERTIES

     As is customary in the oil and gas industry, only a preliminary title
examination is conducted at the time leases of properties believed to be
suitable for drilling operations are acquired by the Company. Prior to the
commencement of drilling operations, a thorough title examination of the drill
site tract is conducted by independent attorneys. Once production from a given
well is established, the Company prepares a division order title report
indicating the proper parties and percentages for payment of production
proceeds, including royalties. The Company believes that titles to its leasehold
properties are good and defensible in accordance with standards generally
acceptable in the oil and gas industry.

EMPLOYEES

     At March 1, 1999, the Company had 64 full time employees.

CERTAIN RISKS

     VOLATILITY OF NATURAL GAS PRICES. The Company's revenues, operating
results, profitability, future rate of growth and the carrying value of its gas
properties are substantially dependent upon prevailing market prices for oil and
gas. Historically, the markets for gas have been volatile and in certain periods
have been depressed by excess domestic and imported supplies. Such volatility is
expected to recur in the future. Various factors beyond the control of the
Company will affect prices of oil and gas, including worldwide and domestic
supplies of oil and gas, the ability of the members of the Organization of
Petroleum Exporting Countries to agree to and maintain oil price and production
controls, political instability or armed conflict in oil or gas producing
regions, the price and level of foreign imports, the level of consumer demand,
the price, availability and acceptance of alternative fuels, the availability of
pipeline capacity, and weather conditions. In addition to market factors,
actions of state and local agencies and the United States and foreign
governments affect oil and gas prices. These external factors and the volatile
nature of the energy markets make it difficult to estimate future prices of gas.
Any substantial or extended decline in the price of gas would have a material
adverse effect on the Company's financial condition and results of operations.
Such decline could reduce the Company's cash flow and borrowing capacity and
both the value and the amount of the Company's gas reserves.

     In order to reduce its exposure to short-term fluctuations in the price of
natural gas, the Company enters into hedging arrangements from time to time. The
Company's hedging arrangements apply to only a portion of its production and
provide only partial price protection against declines in natural gas prices. In
addition, the Company's hedging arrangements limit the benefit to the Company of
increases in the price of natural gas. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations Hedging Transactions" and
"Quantitative and Qualitative Disclosure About Market Risk."

     UNCERTAINTY OF RESERVE INFORMATION AND FUTURE NET REVENUE ESTIMATES. There
are numerous uncertainties inherent in estimating quantities of proved oil and
natural gas reserves and their values, including many factors beyond the
Company's control. Estimates of proved undeveloped reserves, which comprise a
significant portion of the Company's reserves, are by their nature uncertain.
The reserve information set forth in this Form 10-K represents estimates only.
Although the Company believes such estimates to be reasonable, reserve estimates
are imprecise by nature and may materially change as additional information
becomes available.

     Estimates of oil and natural gas reserves, by necessity, are projections
based on geologic and engineering data, and there are uncertainties inherent in
the interpretation of such data as well as the projection of future rates of
production and the timing of development expenditures. Reserve engineering is a
subjective process of estimating underground accumulations of oil and natural
gas that are difficult to measure. The accuracy of any reserve estimate is a
function of the quality of available data, engineering and geological
interpretation and judgment. Estimates of economically recoverable oil and
natural gas reserves and future net cash flows necessarily depend upon a number
of variable factors and assumptions, such as historical production from the area
compared with production from other producing areas, the assumed effects of
regulations by governmental agencies and assumptions governing future oil and
natural gas prices, future operating costs, severance and excise taxes,
development costs and workover and remedial costs, all of which may in fact vary
considerably from actual results. For these reasons, estimates of the
economically recoverable quantities of oil and natural gas attributable to any
particular group of properties, classifications of such reserves based on risk
of recovery, and estimates of the future net cash flows expected therefrom may
vary substantially. Any significant variance in the assumptions could materially
affect the estimated quantity and value of the reserves. Actual production,
revenues and expenditures with respect to the Company's reserves will likely
vary from estimates, and such variances may be material.

     PV-10, as referred to in this Form 10-K, should not be construed as the
current market value of the estimated oil and natural gas reserves attributable
to the Company's properties. In accordance with applicable regulations, the
estimated discounted future net cash flows from proved reserves are based on
prices and costs as of the date of the estimate, whereas actual future prices
and costs may be materially higher or lower. Actual future net cash flows also
will be affected by factors such as the amount and timing of actual production,
supply and demand for natural gas, curtailments or increases in consumption by
natural gas purchasers and changes in governmental regulations or taxation. The
timing of actual future net cash flows from proved reserves, and thus their
actual present value, will be affected by the timing of both the production and
the incidence of expenses in connection with development and production of oil
and natural gas properties. In addition, the 10% discount factor, which is
required to be used to


                                       12
<PAGE>

calculate PV-10 for reporting purposes, is not necessarily the most appropriate
discount factor based on interest rates in effect from time to time and risks
associated with the Company or the oil and natural gas industry in general.

     SPECULATIVE NATURE OF OIL AND GAS EXPLORATION. The business of exploring
for and, to a lesser extent, of developing oil and gas properties is an
inherently speculative activity that involves a high degree of business and
financial risk. Property acquisition decisions generally are based on various
assumptions and subjective judgments that are speculative. Although available
geological and geophysical information can provide information with respect to
the potential of an oil or gas property, it is impossible to predict accurately
the ultimate production potential, if any, of a particular property or well.
Moreover, the successful completion of an oil or gas well does not ensure a
profit on the Company's investment therein. A variety of factors, both
geological and market-related, can cause a well to become uneconomic or
marginally economic.

     OPERATING HAZARDS. The oil and natural gas business involves certain
operating hazards such as well blowouts, craterings, explosions, uncontrollable
flows of oil, natural gas or well fluids, fires, formations with abnormal
pressures, pipeline ruptures or spills, pollution, releases of toxic gas and
other environmental hazards and risks, any of which could result in substantial
losses to the Company. The availability of a ready market for the Company's
natural gas production also depends on the proximity of reserves to, and the
capacity of, natural gas gathering systems and pipelines. The Company delivers
natural gas through gas pipelines that it does not own. Federal and state
regulation of natural gas and oil production and transportation, tax and energy
policies, changes in supply and demand and general economic conditions all could
adversely affect the Company's ability to produce and market its natural gas. In
addition, the Company may be liable for environmental damage caused by previous
owners of property purchased or leased by the Company. As a result, substantial
liabilities to third parties or governmental entities may be incurred, the
payment of which could reduce or eliminate the funds available for exploration,
development or acquisitions and result in losses to the Company. In accordance
with customary industry practices, the Company maintains insurance against some,
but not all, of such risks and losses. The Company carries business interruption
insurance in varying amounts based upon the estimated time to cause the covered
facilities to become operational. The Company may elect to self-insure if
management believes that the cost of insurance, although available, is excessive
relative to the risks presented. The occurrence of an event that is not covered,
or not fully covered, by insurance could have a material adverse effect on the
Company's financial condition and results of operations. In addition, pollution
and environmental risks generally are not fully insurable.

     DEPENDENCE ON GATHERING AND TRANSPORTATION FACILITIES. All of the Company's
current production consists of natural gas. The marketability of the Company's
gas production depends in part upon the availability, proximity and capacity of
gas gathering systems, pipelines and processing facilities. Federal and state
regulation of gas and oil production and transportation, general economic
conditions, changes in supply and changes in demand all could adversely affect
the Company's ability to produce, gather and transport its natural gas. If
market factors were to change materially, the financial impact on the Company
could be substantial. The Company is a party to gas transportation contracts
that require the Company to transport minimum volumes. If the Company ships
smaller volumes, it may be liable for damages proportional to the shortfall. The
Company expects to meet its volume obligations with respect to the Raton Basin
transportation agreement. If the Company is unable to meet its firm
transportation commitments, the commitment must be paid for but can be deferred
and utilized at a later date. While the Company believes that its production in
the Raton Basin will be more than adequate to meet volume requirements,
unforeseen events, including production problems or substantial decreases in the
price for natural gas, could cause the Company to ship less than the required
volumes, resulting in losses on the transportation contracts.

     RISKS OF INTERNATIONAL OPERATIONS. Evergreen holds exploration licenses
onshore in the United Kingdom and in northern Chile, and an interest in a
consortium exploring offshore in the Falkland Islands. International operations
are subject to political, economic and other uncertainties, including, among
others, risk of war, revolution, border disputes, expropriation, re-negotiation
or modification of existing contracts, import, export and transportation
regulations and tariffs, taxation policies, including royalty and tax increases
and retroactive tax claims, exchange controls, limits on allowable levels of
production, currency fluctuations, labor disputes and other uncertainties
arising out of foreign government sovereignty over the Company's international
operations.

     NO DIVIDENDS. The Company has never declared or paid any cash dividends to
the holders of Common Stock and has no present intention to pay cash dividends
to such holders in the foreseeable future.


                                       13
<PAGE>

     CERTAIN ANTI-TAKEOVER MATTERS. The Company's Articles of Incorporation and
Bylaws contain provisions that may have the effect of delaying, deferring or
preventing a change in control of the Company. These provisions, among other
things, provide for noncumulative voting in the election of the Board of
Directors and impose certain procedural requirements on shareholders of the
Company who wish to make nominations for the election of directors or propose
other actions at shareholders' meetings. In addition, the Company's Articles of
Incorporation authorize the Board to issue up to 25,000,000 shares of preferred
stock without shareholder approval and to set the rights, preferences and other
designations, including voting rights, of those shares as the Board of Directors
may determine. These provisions, alone or in combination with each other and
with the Rights Plan described below, may discourage transactions involving
actual or potential changes of control of the Company, including transactions
that otherwise could involve payment of a premium over prevailing market prices
to holders of Common Stock

     On July 7, 1997 the Board of Directors adopted a Shareholder Rights
Agreement ("Rights Plan"), pursuant to which uncertificated stock purchase
rights were distributed to its common shareholders at a rate of one Right for
each share of Common Stock held of record as of July 22, 1997. The Rights Plan
is designed to enhance the Board's ability to prevent an acquirer from depriving
shareholders of the long-term value of their investment and to protect
shareholders against attempts to acquire the Company by means of unfair or
abusive takeover tactics. However, the existence of the Rights Plan may impede a
takeover of the Company not supported by the Board of Directors, including a
takeover which may be desired by a majority of the Company's shareholders or
involving a premium over the prevailing stock price.

     SOUTHERN UTE INDIAN TRIBE V. AMOCO PRODUCTION COMPANY LITIGATION. On
October 21, 1998, President Clinton signed into law a bill that protects
existing royalty ownership of coalbed methane gas produced from existing oil and
gas leases, where the coal rights were severed and owned by the Federal
Government. In the Company's opinion this legislation favorably eliminates the
uncertainty regarding title ownership on any of Evergreen's existing acreage in
the Raton Basin. This legislation was introduced in response to a July 20, 1998,
U.S. Court of Appeals for the Tenth Circuit ruling, Southern Ute Indian Tribe v.
Amoco Production Company, which held that coalbed methane rights may be included
in the definition of "coal" rather than "gas."

ITEM 2.   PROPERTIES

OPERATIONS

     The Company's wholly-owned subsidiary, Evergreen Operating Corporation
("EOC"), is primarily responsible for drilling, evaluation and production
activities associated with various properties and for negotiating the sales of
oil and gas production from the properties. As of March 1, 1999, EOC was serving
as operator for approximately 173 producing wells owned by the Company.

     The Company believes that, as operator, it is in a better position to
control costs, safety, and timeliness of work as well as other critical factors
affecting the economics of a well or a property, including maintaining good
community relations.

     EOC presently operates wells which represent 100% of Evergreen's proved
reserves.

PRINCIPAL PROPERTIES

     The following are brief descriptions of Evergreen's principal properties:

RATON BASIN PROPERTIES AND OPERATIONS

     The Raton Basin is an onshore depositional and structural basin that is
approximately 80 miles long and 50 miles wide, located in southern Colorado and
northern New Mexico. The Raton Basin contains two coal bearing formations, the
Vermejo formation coals located at depths of between 450 and 3,500 feet and the
shallower Raton formation coals, located at depths from the surface to
approximately 2,000 feet. To date, Evergreen's primary production has been from
the Vermejo formation coal seams; however, Evergreen believes that the Raton
formation coal seams may be profitably exploited as well.

     DEVELOPMENT HISTORY AND EXPECTED FUTURE DEVELOPMENT. Exploration for
coalbed methane began in the Raton Basin in the late 1970s and continued through
the late 1980s, with several companies drilling and testing over 100 wells
during this period. The absence of a pipeline to transport gas out of the Raton
Basin prevented full-scale development until January 1995, when CIG's Picketwire
Lateral became operational.

     Since December 1991, Evergreen has acquired oil and gas leases covering
approximately 200,000 gross acres in the Raton Basin. The initial 70,000 acres
were acquired from Amoco Production Company ("Amoco") in 1991 by direct purchase
without overriding royalties. The majority of the acreage remaining was
purchased during 1992 and 1993 from individual owners under various lease terms.
Generally, the lease terms provide for a 12 1/2% royalty interest to the owner
of the mineral rights. In August 1993, a four well evaluation program was
conducted by the Company. Based on positive results from the initial four wells,
the Company made the decision, in August 1994, to focus all domestic efforts on
development of the Raton Basin. Evergreen currently has 173 net producing gas
wells on its Raton Basin properties.

     In March 1995, the Federal Bureau of Land Management ("BLM") designated 
approximately 67,000 acres of Evergreen's leases in the Raton Basin as a 
federal unit called the Spanish Peaks Unit. In December 1997, the BLM 
approved an additional 6,300 acres of leases to be included in the Spanish 
Peaks Unit, for a total of 73,300 acres. In January 1997, the BLM designated 
an additional 33,000 acres of Evergreen's leases as a federal unit called the 
Sangre de Cristo Unit. Additionally, in July 1998, the Company acquired a 
100% working interest in 27,590 gross acres in the Cottontail Pass Federal 
Unit from Amoco. The Cottontail Pass Unit is situated between Evergreen's 
Spanish Peaks and Sangre de Cristo Units. Evergreen has been named the 
operator for all three of these units. Formation of a unit simplifies lease 
maintenance so that Evergreen, as the operator, can base development 
decisions within the unit on geologic, operational and cultural 
considerations rather than the fulfillment of lease-term obligations.

     Because of the inclusion of federal leases in the unit, operation and
production within a federal unit is governed by federal rules. Production from
any well in the unit area will maintain all of the leases beyond their primary
terms. In October 1997, the first "participating area" was designated by the BLM
under the Unit Agreement. Gas production in the participating area will be
pooled and shared by the royalty owners, overriding royalty owners and working
interest owners in that area in proportion to their acreage ownership of the
mineral estate in the area. The participating area will be adjusted annually to
encompass additional acreage as additional wells are completed.

     Prior to the acquisitions of the Cottontail Pass Unit and acreage in the
Long Canyon and Lorencito areas (discussed below), the Company's principal
development activities in the Raton Basin had been in the Spanish Peaks Unit.
The Company currently has 130 producing wells in this Unit and expects to drill
approximately 80 wells there in 1999. Current production from the Spanish Peaks
Unit is approximately 36 MMcf per day. The Company has identified approximately
400 drilling locations in its Spanish Peaks Unit, of which 207 were included in
the Company's proved reserve base at December 31, 1998. These identified
locations comprise approximately 52% of the Company's total acreage in the
Spanish Peaks Unit. The Company has also drilled two exploratory wells in the
northern portion of the Spanish Peaks Unit to determine the development
potential for commercial production of the shallower Raton formation coals, as
well as the Vermejo formation coals.


                                       17
<PAGE>

     The Company's development activities in the Sangre de Cristo Unit have
consisted solely of the drilling of four exploratory wells. These exploratory
wells will test production levels, provide additional geologic control, and also
will fulfill unit obligations. The Company will be required to construct a
compression facility and a gathering facility to enable gas production and sales
from this unit. No reserves from wells in the Sangre de Cristo Unit are included
in the Company's reserve base.

     Effective July 1, 1998, Evergreen acquired approximately 100% of the
working interest in 27,590 acres in Amoco's Cottontail Pass Federal Unit.
Included in the acquisition were 28 producing wells and gathering facilities.
Total daily production is approximately 5 MMcf per day. The Company estimates
that there are approximately 100 additional drilling locations in the Unit.

     Effective December 31, 1998, the Company acquired 41,000 gross acres in the
Long Canyon and Lorencito areas located in the southern Colorado portion of the
Raton Basin. The properties included 19 currently producing wells with daily
production of approximately 1.5 MMcf per day. Evergreen has identified 160
potential drilling locations on the acreage, in which it will hold working
interests of between 53% and 75% and serve as operator.

     RATON BASIN GEOLOGY. In the Raton Basin, Evergreen produces methane 
almost entirely from the Vermejo coals, consisting of several individual 
seams ranging in thickness between 1 and 12 feet, and at drilling depths 
between 450 and 3,500 feet below the surface. The entire Vermejo coal 
interval ranges from 5 to 50 feet thick through the Raton Basin, being 
thickest in the center of the Basin, which the Company's acreage surrounds. 
The coal beds and surrounding sedimentary rocks formed during the late 
Cretaceous to early Tertiary period, between 65 and 40 million years ago. The 
Raton Basin is a highly asymmetric downward fold in the earth's crust that is 
approximately 80 miles long north to south and about 50 miles wide east to 
west. Plant material accumulated in thick layers within coastal swamps in the 
Raton Basin and was subsequently buried and subjected to heat and pressure 
which formed the coals. Since these coals were buried, continued mountain 
building in combination with basin downwarping, created an extensive series 
of faults and fractures in the coals and surrounding rocks. Later, the area 
was intruded by hot liquid rock or "magma" from lower in the earth's crust, 
which cooled to form two large mountain structures in the center of the Raton 
Basin known as the Spanish Peaks. The magma moved up through existing faults 
and fractures and created additional fractures that radiate outward from the 
Spanish Peaks. As the magma cooled, its heat altered the surrounding rocks, 
including the Vermejo and Raton coalbeds. The Company believes that the 
simultaneous downwarping of the Raton trough and Larimide age mountain 
building with subsequent relaxation (extension) and the subsequent magmatic 
intrusions into the Raton Basin have matured the coals and enhanced the 
ability of the Vermejo and Raton coals to yield coalbed methane gas.

     In the Raton Basin, the Company has found some coal seams to be 
continuous between wells over distances of several miles, though the 
thickness of these beds are variable. Evergreen is currently completing its 
wells in the Vermejo coal beds, and expects to test the Raton coal beds 
extensively this year. Individual wells are often completed to produce gas 
from 5 to 15 individual coalbeds with individual thickness between 1 and 12 
feet.

COALBED METHANE VERSUS TRADITIONAL NATURAL GAS

     Methane is the primary commercial component of the natural gas stream 
produced from traditional gas wells. Methane also exists in its natural state 
in coal seams. Natural gas produced from traditional wells also contains, in 
varying amounts, other hydrocarbons. However, the natural gas produced from 
coalbeds generally contains only methane and, after simple water dehydration, 
is pipeline-quality gas.

     Coalbed methane production is similar to traditional natural gas production
in terms of the physical producing facilities and the product produced. However,
the subsurface mechanisms that allow the gas to move to the wellbore and the
producing characteristics of coalbed methane wells are very different from
traditional natural gas production. Unlike conventional gas wells, which require
a porous and permeable reservoir, hydrocarbon migration and a natural structural
or stratigraphic trap, the coalbed methane gas is trapped in the molecular
structure of the coal itself until released by pressure changes resulting from
the removal of insitu water.

     Methane is a common component of coal since methane is created as part of
the coalification process, though coals vary in their methane content per ton.
In addition to being in open spaces in the coal structure, methane is


                                       18
<PAGE>

absorbed onto the inner coal surfaces. When the coal is hydraulically 
fracture stimulated and exposed to lower pressures through the de-watering 
process, the gas leaves (desorbs from) the coal. Whether a coalbed will 
produce commercial quantities of methane gas depends on the coal quality, its 
original content of gas per ton of coal, the thickness of the coal beds, the 
reservoir pressure and the existence of natural fractures (permeability) 
through which the released gas can flow to the wellbore. Frequently, coalbeds 
are partly or completely saturated with water. As the water is produced, 
internal pressures on the coal are decreased, allowing the gas to desorb from 
the coal and flow to the wellbore. Contrary to traditional gas wells, new 
coalbed methane wells often produce water for several months and then, as the 
water production decreases, natural gas production increases because the coal 
seams are being de-watered and the resultant pressure on the coal decreases.

     In order to establish commercial gas production rates, a permanent 
conduit between the individual coal seams and the wellbore must be created. 
This is accomplished by hydraulically creating and propping open with special 
quality sand, artificial fractures within the coal seams (known as "fracing" 
in the industry) so the pathway for gas migration to the wellbore is 
enhanced. These fractures are filled (propped) with uniformed sized sand and 
become the conduits for methane to reach the well. The ability of gas to move 
through the coal or rocks to the wellbore from its place of origination in 
the formation is the key determinant of the rate at which a well will produce.

     COALBED METHANE TECHNOLOGY. The Company, working in conjunction with its
contractors, has developed what it believes to be effective procedures for
fracing the Vermejo coals in its Raton Basin wells. In addition, the Company has
developed well completion and specialized drilling techniques that are suited to
its Raton Basin wells. Traditional gas wells are drilled with the use of rotary
drill bits cooled and lubricated by drilling fluids or "mud." Coalbed methane
production is particularly sensitive to the natural permeability of the coals.
Exposing the Raton Basin coals to drilling mud appears to significantly reduce
the permeability of the coals by plugging the cleat system and natural fractures
in the coals. The Company, therefore, uses percussion air drilling (similar to a
jackhammer) without traditional drilling muds in drilling its wells.

     WATER PRODUCTION AND DISPOSAL. To date, the majority of the water 
produced from the Company's Raton Basin coal seams has been low in total 
dissolved solids, allowing the Company, operating under permits issued by the 
State of Colorado, to discharge the water into well-site pits and off well-site 
evaporation ponds. If more brackish water is encountered in subsequent 
wells, it may be necessary to drill specialized injection wells to re-inject 
the produced water back into the underground rock formations.

     RATON BASIN PRODUCTION. Evergreen's natural gas sales from the Raton Basin
did not commence until the completion of a pipeline system in January 1995,
which connected the Company's Raton Basin wells to the CIG pipelines. From
January 1995 through December 1998, Evergreen sold an aggregate of approximately
18.5 Bcf of coalbed methane gas from the Raton Basin. Gross daily production
from the field currently exceeds 43 MMcf per day. Because of the importance of
removing water from the coal seams to enhance gas production, Evergreen expects
to continue production from more modest wells because of the beneficial ambient
effect of pressure reduction in adjacent, more productive wells. Each well
creates its own "cone of depression" in the water saturation around the
wellbore. The Company believes that some of its Raton Basin wells on adjacent
160-acre drill sites have already created overlapping cones of depression,
enhancing gas production in each well.

     The Raton Basin gas does not contain significant amounts of contaminants,
such as hydrogen sulfide, carbon dioxide or nitrogen, that are sometimes present
in traditional natural gas production. Therefore, the properties of the Raton
Basin gas, such as heat content per unit volume (Btu), are very close to the
average properties of pipeline gas from conventional gas wells.

INTERNATIONAL PROPERTIES AND OPERATIONS

     UNITED KINGDOM. In 1991 and 1992, the Company's wholly-owned subsidiary,
Evergreen Resources (U.K.) Ltd. ("ERUK"), was awarded seven onshore United
Kingdom hydrocarbon exploration licenses for the development of coalbed methane
gas and conventional hydrocarbons (the "Original Licenses"). The Original
Licenses provided ERUK with the largest onshore acreage position in the United
Kingdom, covering substantially all of six distinct onshore United Kingdom
basins.


                                       19
<PAGE>

     Selection of the licensed areas was made after evaluating geological,
geophysical, petrophysical and measured methane gas content data bases. The
majority of the original data base was acquired through technology sharing
agreements with British Coal Corporation, which shared relevant available data
on the six basins and granted use of this data to ERUK. ERUK has augmented this
data with proprietary seismic and coalbed methane well data and also geologic
data from the British Geologic Survey, and other sources.

     During the period from 1992 to 1994, Evergreen conducted seismic work and
drilled three wells under two of the Original Licenses. The wells encountered 30
feet to 80 feet of gross coal. Two of the wells were hydraulically fracture
stimulated and one was tested for permeability. Following extensive production
testing, none of the three wells produced gas in economic quantities. The three
wells are presently shut-in.

     In 1997, under a new onshore licensing regime implemented by the U.K.
Department of Trade and Industry, Evergreen converted its Original Licenses to
new onshore Licenses, called Petroleum Exploration and Development Licenses (the
"Current Licenses"). In connection with such conversion, the Company
relinquished rights to approximately 259,000 acres, which were not considered
highly prospective for coalbed methane development. Under the Current Licenses,
the Company retains approximately 377,000 acres, which were high-graded for
coalbed methane and conventional hydrocarbon potential. Subsequent to year-end,
the Company acquired an additional 136,000 acres. The Current Licenses provide
up to a 30-year term with optional periodic relinquishment of portions of the
Licenses, subject to future development plans. There are no royalties or burdens
encumbering these Licenses. Work commitments for acreage retained will include
the drilling of three wells in 1999.

     Evergreen believes that a major coalbed methane resource exists within the
areas subject to the Current Licenses. However, further evaluation will be
required to confirm such belief and determine the economic viability of
extracting any such reserves. Evaluation is expected to occur on a
License-by-License basis, since success or lack of success on one License may
not be translated to similar results on other Licenses or separate geologic
basins. Evergreen will spend approximately $3 million in 1999 to drill gob gas
wells and maintain the Licenses.

     The Company has recently completed a 3D seismic program in the United 
Kingdom in an area in which Evergreen plans to drill a multi-well pilot 
coalbed methane project. Evergreen is holding discussions with potential 
industry partners for the purpose of evaluating and developing the Current 
Licenses and will not start the pilot program until a partner has been 
secured. The Company has recently purchased a drilling rig for this project. 
This rig initially will be tested in the Raton Basin and shipped to the 
United Kingdom for the drilling of the seven wells in the second half of 1999.

     In addition to the drilling of coalbed methane wells, the Company will 
drill approximately 5-6 gob gas wells. Gob gas is essentially methane gas 
that has collected in abandoned underground coal mines. Evergreen plans to 
establish marketing arrangements for its future gas production by first 
supplying this gob gas to local electric power plants. The Company plans to 
start the gob gas drilling and production in the second half of 1999.

     FALKLAND ISLANDS. The Falkland Islands consortium, in which Evergreen has a
net 2% interest, has completed operations on the second well (and the industry's
fifth well) in the North Falklands Basin. Well 14/9-2 was spudded on October 13,
1998, and finished drilling on October 28, 1998. It reached a total depth of
approximately 8,000 feet and was plugged and abandoned as a dry hole with oil
shows.

     The abandonment of well 14/9-2 completes the initial drilling campaign on
Tranche A. The two wells on Tranche A have established good source rocks and
potential reservoir rocks. The consortium will assess the data gathered from the
two wells to determine the future strategy for the acreage.

     CHILE. In March 1997, the Government of Chile awarded an oil and gas 
exploration license to Evergreen on two 5,000 square kilometer (approximately 
1.2 million acres) blocks in northern Chile. Evergreen has a 75% working 
interest in the blocks and will serve as operator. ENAP, the Chilean-owned 
energy company, holds the remaining 25% working interest. The Chilean 
government will initially receive a 10% royalty on production up to 10,000 
barrels per day, which increases up to a maximum of 35% on production in 
excess of 100,000 barrels per day.

     Evergreen and ENAP will share work commitments proportionately for the
periods of time stated as Exploration Periods for each block as set forth in the
table below:

</TABLE>

     *  Commenced June, 1997 - fulfilled

     Evergreen and ENAP may relinquish up to 100% of the blocks at the end of
each exploration period. If the blocks go into production, the contracts will
last 35 years.

     Evergreen expects that the foregoing activities will require capital
expenditures over the next two years of approximately $2.2 million.

OFFICE AND OPERATIONS FACILITIES

     The Company leases its corporate offices in Denver, Colorado. Effective May
1, 1998, the Company entered into a new ten year office lease for approximately
$267,500 per year. The Company believes the new office space will be sufficient
for the foreseeable future.

ITEM 3.   LEGAL PROCEEDINGS

     Except for the proceedings referenced below, the Company is not involved in
any material pending legal proceedings to which the Company or its subsidiary is
a party or to which any of its property is subject.

     On July 13, 1998, Southern Colorado C.U.R.E. filed a lawsuit under the 
citizen suit provision of the Clean Water Act in the U.S. District Court for 
the District of Colorado against EOC, related to its coalbed methane drilling 
operations in the Raton Basin near Trinidad, Colorado. The Company's gas 
production produces naturally occurring groundwater as a by-product of its 
coalbed methane gas production operations. The storage, use and disposal of 
the produced groundwater in evaporative ponds and natural collection features 
located on the surface at or near the wellsite, and the legal and regulatory 
treatment of this practice, underlie the lawsuit. EOC is also subject to 
federal, state and local environmental laws and regulations, and is currently 
participating with the EPA and the State of Colorado in the investigation of 
certain practices in connection with these operations. An evaluation of costs 
of potential liabilities associated with this investigation cannot be 
reasonably determined at this time. The Company does not expect that the 
lawsuit or the investigation, or the environmental costs or contingent 
liabilities of either, if any, will have a material adverse effect on its 
consolidated financial position or its results of operations.

Results of Operations" regarding the settlement of the Evergreen versus Amoco 
Production Company lawsuit.

LIQUIDITY AND CAPITAL RESOURCES

     During the year ended December 31, 1998, the Company continued to 
demonstrate consistent growth over prior years in the areas of pre-tax net 
income, cash flow and gas reserves. Recent property acquisitions in the Raton 
Basin have enhanced Evergreen's position in the Basin with an increase in the 
number of drilling locations and with anticipated economies with its gas 
gathering system.

     During the year ended December 31, 1998, the Company acquired additional 
property interests in the Raton Basin. On July 2, 1998, Evergreen completed 
the acquisition of approximately 27,000 acres in the Cottontail Pass Federal 
Unit in the Raton Basin and 28 existing wells and related gathering 
facilities for $13.1 million in cash. Effective December 31, 1998, the 
Company acquired 41,000 gross acres in the Raton Basin and 17 producing wells 
for stock valued at $7.5 million, the assumption of approximately $750,000 in 
debt and $250,000 in cash. In the aggregate, the Company acquired a total of 
60.4 MMcf of proved reserves at an acquisition finding cost of $0.36 per Mcf.

     The acquisition of the Cottontail Pass Federal Unit from Amoco resolved the
preferential rights litigation between Evergreen and Amoco. On June 25, 1997,
Evergreen filed an action seeking a declaratory judgement against Amoco
regarding a proposed sale by Amoco of the Cottontail Pass Federal Unit, located
in the Raton Basin. Evergreen, as a working interest owner in the unit, had a
preferential right to purchase approximately 22,000 gross non-producing acres.
Evergreen had tendered to Amoco notice of its intention to exercise this
preferential right to


                                       24
<PAGE>

purchase; however, Amoco contended that it did not receive valid notice of the
preferential purchase rights from Evergreen. Evergreen sought a declaratory
judgement that Evergreen had properly exercised its preferential right of
purchase, and that Amoco was obligated to sell the properties covered by that
right of purchase to Evergreen. On November 12, 1997, the court granted
Evergreen's motion for summary judgement and ruled that Evergreen properly
exercised its right of purchase for the subject properties. Subsequent to that
ruling, the Company successfully negotiated the purchase of the entire
Cottontail Pass Unit from Amoco.

     During 1999, the Company anticipates that it will drill approximately 80
wells in the Raton Basin and will spend approximately $45 million on its total
exploration and development program. Drilling and gathering facilities will
comprise approximately $35 million. Approximately 25% of the drilling and
gathering costs will be incurred for the completion of a second compressor
station in the northern portion of the Spanish Peaks Unit along with the related
infrastructure, a 24-inch trunk gathering line and a 12-inch high pressure sales
line that connects to the CIG's Picketwire Lateral. These items are required due
to pressure constraints in the existing gathering system caused by increasing
pressures and additional gas volumes from newer wells drilled. The compressor
station and the infrastructure are needed to optimize production in the Spanish
Peaks and Cottontail Pass Units.

     In addition, the Company plans to spend approximately $5 million in new 
equipment for a new well service company. In February 1999, the Company sold 
its 49% interest in Maverick Stimulation Company ("Maverick") for 
approximately $2.25 million. The new well service company will be a 
wholly-owned subsidiary of Evergreen. The well service company will provide 
fracture stimulation services, cement work, drilling and workovers. Evergreen 
anticipates an increase in quality control and cost savings from the services 
performed.

     The remaining budget is for international exploration, including the $3 
million for drilling of the gob gas wells in the UK and other miscellaneous 
items. No budget has been allocated to the multi-well drilling program. 
Evergreen is holding discussions with potential industry partners for the 
purpose of evaluating and developing the Current Licenses and will not start 
the multi-well program until an investment in the project by a partner has 
been secured.

     The capital budget for 1999 is subject to review and adjustment depending
on gas prices and the corresponding cash flow. The Company believes that cash
flow from operations and available borrowings under its line of credit will be
sufficient to fund 1999 capital expenditures for the Raton Basin and the
drilling of gob gas wells in the UK. Future development of the Raton Basin and
other projects will require additional capital. The Company believes it will
have sufficient capacity to fund all of its projects for the foreseeable future
through its anticipated cash flow and its lines of credit. However, as the
Company continues to grow and expand, the Company believes that additional
equity capital may be required to fund development of its projects.

     As of December 31, 1998, the Company currently had a $50 million revolving
line of credit with a bank group consisting of Hibernia National Bank, as agent,
Chase Bank of Texas and Paribas ("the Banks"). The line is available through
June 2001. Advances pursuant to this line of credit are limited to a borrowing
base, which is presently $50 million. At the Company's election, it may use
either the London interbank offered rate ("Libor") plus a margin of 1.38% to
1.75% or the prime rate plus a margin of 0% to .25%, with margins on both rates
determined on the average outstanding borrowings under the credit facility. The
borrowing base is redetermined semi-annually by the Banks based upon reserve
evaluations of the Company's oil and gas properties. The current borrowing base
is less than the total borrowing base that could have been requested under the
terms of the agreement. An annual facility fee of .375% is charged quarterly for
any unused portion of the credit line. The agreement is collateralized by oil
and gas properties and also contains certain net worth and ratio requirements.
At December 31, 1998, $44,138,700 was outstanding under the line of credit.
Effective March 1, 1999, the Company increased its line of credit to $75 million
with the same terms and conditions as the current line of credit. As of March 1,
1999, the borrowing base is $75 million.

     The Company has a capital equipment lease with a bank with interest at 
8.5% at December 31, 1998. The capital equipment lease has a term of five 
years ending April 2002, with an option to purchase the equipment at nominal 
amounts at the end of the lease term. The Company primarily leases 
compressors for the Raton Basin gas gathering system and other related 
production equipment. At December 31, 1998, the Company had approximately $4 
million under the capital lease obligations.

                                       25
<PAGE>

     Prior to 1998, the Company had not been required to record income tax
expense, primarily due to the availability of net operating loss carryovers.
However, as a result of the recently reported profitability and the significant
difference between the book and tax basis of assets, the Company will be
required to provide for deferred income taxes in the statement of income in 1998
and subsequent years. The Company recorded a deferred tax provision of
approximately $3,279,000 in 1998. The Company estimates that it will not be
required to pay current income tax in the near future due to the availability of
net operating loss carryforwards of approximately $30 million and current
deductions for intangible drilling costs.

     Cash flows provided by operating activities were $12,147,100 for the year
ended December 31, 1998 as compared to cash flows provided by operating
activities of $6,547,400 for the year ended December 31, 1997. The significant
increase in the cash flows provided by operating activities is due primarily to
improved operating results as a result of increased gas production. The
increased gas production is due to the drilling of additional wells and the
acquisition of certain producing properties.

     Cash flows used in investing activities were $47,202,500 during the year
ended December 31, 1998, versus $19,259,200 in 1997. The increase in 1998 was
due to the continued development of the Raton Basin, investments in
international projects and the acquisition of the Cottontail Pass Unit for
$13,100,000.

     Cash flows provided by financing activities were $34,259,800 during the
year ended December 31, 1998, as compared to cash flows provided by financing
activities of $12,253,000 in 1997. The increase was due primarily to increased
borrowings to fund the development of the drilling and gathering system in the
Raton Basin as well as the acquisition of the Cottontail Pass Unit. In addition,
the Company received proceeds from the exercise of stock purchase warrants of
approximately $2,158,200. These borrowings and exercise of stock purchase
warrants were offset by principal payments on capital leases of $1,061,100.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

     The Company reported net income of $5,212,000 or $0.47 per diluted share 
for the year ended December 31, 1998, compared to net income of $5,064,000 or 
$0.51 per diluted share for the same period in 1997. Pretax net income 
increased significantly to $8,491,000 in 1998, versus $5,464,000 in 1997. As 
a result of a deferred income tax provision of $3,279,000 in 1998 as compared 
to no deferred income tax provision in 1997, the Company's 1998 net income 
increased slightly as compared to 1997.

     Natural gas revenues increased to $19,063,000 during the year ended 
December 31, 1998 from $12,138,000 for the same period in the prior year. The 
significant increase of $6,925,000 in 1998 compared to 1997 or 57% was due to 
the increase in production and the acquisition of certain properties in the 
Raton Basin. The Company had 159 net producing wells in 1998, versus 89 in 
1997. The number of producing wells in the Spanish Peaks Unit increased to 
127 in 1998, versus 89 in 1997. The Company acquired approximately 32 net 
producing wells in two separate transactions in 1998. Gas production volumes 
in the Spanish Peaks Unit increased to 9,458,000 Mcf in 1998 versus 6,402,000 
Mcf in 1997, or 48%. Gas production volumes from the acquired properties were 
563,000 Mcf in 1998. The average gas price for 1998 and 1997 was $1.90 per 
Mcf.

     Equity in earnings of investment increased to $555,000 during the year 
ended December 31, 1998 as compared to $313,000 in 1997. Equity in earnings 
of investment is due to the Company's 49% ownership in Maverick, an oil and 
gas well servicing company. The Company accounts for the investment in 
Maverick under the equity method of accounting. The increase was due to 
Maverick's increase in sales volume and profitability in 1998 as compared to 
1997. Subsequent to year-end, the Company sold its 49% interest in Maverick 
to the managing members of Maverick for cash of approximately $2.25 million. 
The closing of the transaction is expected to occur in April 1999. As a 
result of the sale of Maverick, the Company will not have future earnings 
from its investment for 1999. However, any loss of projected income in 1999 
from Maverick will be more than offset by the gain on the sale of Evergreen's 
interest.

     Interest and other income increased to $178,000 during the year ended
December 31, 1998 as compared to $137,000 in 1997. The increase is due to
changes in cash management in 1998.


                                       26
<PAGE>

     Lease operating expenses for the year ended December 31, 1998 were
$3,356,000 as compared to $2,007,000 for the same period in 1997. On an
equivalent basis (Mcfe), lease operating expenses were $0.34 per Mcfe in 1998
versus $0.31 per Mcfe in 1997. The $0.03 increase for 1998 over the prior year
is primarily due to an increase in water management costs. The increase in water
management costs is due to drilling wells where there has been a significant
increase in water production. The Company estimates that the lease operating
expense per Mcfe will be at this higher level for some portion of the first
quarter of 1999, but should decrease during the year. The decrease in lease
operating expenses is expected due to the approval of the discharge permits
effective late in January 1999 and the drilling of disposal wells in 1999.

     Depreciation, depletion and amortization expense for the year ended
December 31, 1998 was $3,860,000 versus $2,794,000 in 1997. On an equivalent
Mcfe basis, depreciation, depletion and amortization expense declined to $0.39
per Mcfe in 1998 as compared to $0.44 in 1997. The decrease in cost per Mcfe in
1998 as compared to 1997 is due to amortizing capital costs over a significantly
greater number of units of proved reserves.

     General and administrative expenses were $1,933,000 during the year ended
December 31, 1998 versus $1,286,000 in 1997. The increase in 1998 of $647,000 is
due to the expected increase in the overall growth in corporate activity. During
1998, personnel costs increased due to the addition of new staff, salary
increases and related benefits, insurance costs, office rent and other
miscellaneous operating expense items. Although the overall general and
administrative expenses increased for the year ended December 31, 1998, the cost
per Mcfe decreased to $.19 in 1998 from $.20 in 1997. The oil and gas service
income and the related cost of service have been reclassified and included with
general and administrative expenses for the year ended December 31, 1998 and for
all periods presented. Through March 1999, EOC operated properties for various
third party working interest owners. In January 1999, the working interest
owners sold those properties. As EOC will no longer receive overhead charges for
the operation of those properties, the Company's general and administrative
expenses will increase in future periods.

     Interest expense was $1,870,000 during the year ended December 31, 1998 as
compared to $777,000 in 1997. The $1,093,000 increase for 1998 over the same
period in the prior year is due to increased borrowings under the Company's line
of credit to $44,139,000 from $10,812,000 in 1997. The increase in borrowings is
due to the continuing development in the Raton Basin along with the acquisition
of the Cottontail Pass Unit on July 2, 1998 in the amount of $13.1 million. On
July 1, 1998, the Company increased its line of credit to $50 million and also
changed the interest rate from a prime rate based loan to a Libor based rate.
The change in interest rates decreased the Company's effective interest rate in
the last half of 1998 by 142 basis points to 7.25%.

     Prior to 1998, the Company was not required to record income tax expense,
primarily due to the availability of net operating loss carryforwards. However,
as a result of the recently reported profitability and the significant
difference between the book and tax basis of assets, the Company is required to
provide for deferred income taxes in the statements of income in 1998 and
subsequent years. The Company estimates that it will not be required to pay
current income tax in the near future due to the availability of net operating
loss carryforwards of approximately $30 million and current deductions for
intangible drilling costs. For the year ended December 31, 1998, the Company
recorded a deferred tax provision of $3,279,000.

     Other expense was $286,000 for the year ended December 31, 1998 as compared
to $259,000 in 1997. Other expense in 1998 included a write-off of offering
expenses of $220,000 related to the withdrawal of a registration on file with
the Securities and Exchange Commission due to unfavorable market condition.
Other expenses in 1997 included a write-off of a receivable in the amount of
approximately $150,000 that was deemed uncollectible and gas gathering costs of
$112,000.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO NINE MONTHS ENDED DECEMBER 31, 1996

     Net income for the year ended December 31, 1997 was $5,064,000 or $0.51 per
diluted share, as compared to $675,000 or $0.10 per diluted share, for the nine
months ended December 31, 1996. The increase in net income was primarily the
result of the increase in natural gas net revenues resulting from an increase in
gas production and gas prices and a twelve month reporting period as compared to
a nine month reporting period.

     Natural gas revenues were $12,138,000 during the year ended December 31,
1997 as compared to $3,502,000 for the nine months ended December 31, 1996. The
significant increase in oil and gas revenue during 1997, as

                                       27
<PAGE>

compared to 1996, was attributable to substantially higher Raton Basin
production volumes and higher natural gas prices and a twelve month reporting
period as compared to a nine month reporting period. The average gas prices were
$1.90 per Mcf for the year ended December 31, 1997 as compared to $1.66 per Mcf
in 1996. Natural gas production increased to 6,401,500 Mcf for the year ended
December 31, 1997 as compared to 2,104,400 Mcf for 1996.

     At December 31, 1997 there were 89 producing Raton Basin wells compared to
42 producing wells at December 31, 1996.

     Equity in earnings of investment was $313,000 for the year ended December
31, 1997. Equity in earnings of investment was due to the Company's 49%
ownership in Maverick, an oil and gas well servicing company. The Company
accounts for the investment in Maverick under the equity method of accounting.
Prior to the year ended December 31, 1997, the Company's share of Maverick
profits after intercompany elimination was not material. The increase in
Maverick's net income in 1997 was due to the increase in its oil and gas
stimulation services for third-party entities.

     Interest income and other decreased to $137,000 for the year ended December
31, 1997 from $180,000 for the nine months ended December 31, 1996. This
decrease was due to less cash to invest as a result of the continued Raton Basin
development.

     Lease operating expenses for the year ended December 31, 1997 were
$2,007,000 compared to $701,000 for the nine months ended December 31, 1996.
Lease operating expenses per Mcfe declined to $0.31 during the year ended
December 31, 1997 from $0.33 in 1996. The decrease in the average lease
operating expense per Mcfe was due to the economies of scale resulting from the
increase in producing wells in the Raton Basin.

     Depreciation, depletion, and amortization expenses for the year ended
December 31, 1997 increased to $2,794,000 as compared to $966,000 for the nine
months ended December 31, 1996. The increase of $1,828,000 was due to the
substantial increase in natural gas production and a twelve month reporting
period as compared to a nine month reporting period.

     General and administrative expenses increased to $1,286,000 for the year
ended December 31, 1997 as compared to $581,000 for the nine months ended
December 31, 1996. The $705,000 increase was due to the general increase in
overall corporate activity, including salaries and professional services and a
twelve month reporting period as compared to a nine month reporting period.
Although the overall expense increased for the twelve months ended December 31,
1997, the cost per Mcfe decreased to $.20 from the prior year cost per Mcfe of
$0.28. The oil and gas service income and related cost of service have been
reclassified and included with general and administrative for all periods
presented.

     Interest expense increased to $777,000 for the year ended December 31, 1997
from $193,000 for the nine months ended December 31, 1996. This $584,000
increase was due to increased borrowings under the Company's line of credit and
an increase in the capital equipment lease. The increased borrowings were made
to fund the Raton Basin development.

     Other expenses increased to $259,000 for the year ended December 31, 1997
from $128,000 for the nine months ended December 31, 1996. The increase in other
expenses was due primarily to the write-off of a receivable that was deemed
uncollectible.

HEDGING TRANSACTIONS

     The Company enters into contractual obligations that require future 
physical delivery of its natural gas production to attempt to manage price 
risk with regard to a portion of its natural gas production. As of December 
31, 1998, the Company had entered into contracts to sell approximately 10,000 
MMbtu's per day through October 31, 1999 at a fixed price of $1.61 per Mcf. 
Subsequent to year-end the Company entered into contracts to sell 
approximately 20,000 MMBtu's per day for the period from April 1, 1999, 
through October 31, 1999, at an average fixed price of approximately $1.46 
per Mcf. The total aggregate average fixed price for all contracts is 
approximately $1.50 per Mcf.

     The Company identifies minimum internal price targets and, assuming other
market conditions are deemed favorable, the Company will enter into hedging
contracts to manage price risk. See "Quantitative and Qualitative Disclosure
About Market Risk."

INCOME TAXES AND NET OPERATING LOSSES

     As discussed in Note 7 of the Notes to the Company's Consolidated Financial
Statements, the Company has net operating loss carryforwards for income tax
purposes of approximately $30 million which expire beginning in 1999.

     The Company recorded a valuation allowance at December 31, 1996 equal to
the excess of deferred tax assets over deferred tax liabilities as it was unable
to determine that the deferred tax assets were more likely than not to be
realized. As of December 31, 1997, the Company did not record a valuation
allowance since management was able to determine that it was more likely than
not that the deferred tax asset would be realized. Management expects to fully
utilize its net operating loss carryforwards against reversing temporary
differences.

     Prior to 1998, the Company has not been required to record income tax 
expense, primarily due to the availability of net operating loss 
carryforwards. However, as a result of the recently reported profitability 
and the significant difference between the book and tax basis of assets, the 
Company will be required to provide for deferred income taxes in the 
statements of income in 1998 and subsequent years. The Company estimates that 
it will not be required to pay current income tax in the near future due to 
the availability of net operating loss carryforwards of approximately $30 
million and current deductions for intangible drilling costs.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for
Derivative Instruments and Hedging Activities," which establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts and for hedging activities. SFAS No. 133
is effective for all fiscal quarters of fiscal years beginning after June 15,
1999. Management believes the adoption of this statement will not have a
material impact on the Company's financial statements.

YEAR 2000

     The Company has conducted a review of its computer systems to identify the
systems that could be affected by the "Year 2000" issue. The Year 2000 problem
is the result of computer programs being written using two digits rather than
four to define the applicable year. Any of the Company's programs that have
time-sensitive software may recognize a date using `00' as the year 1900 rather
than the year 2000. This could result in a major system failure or
miscalculations.

     The Company believes that the Year 2000 problem will not pose material
operational problems for the Company and that it is adequately prepared for the
Year 2000. The Company's computer software provider has assured the Company that
all of the Company's software is Year 2000 compliant (i.e. will function
properly in the year 2000 and beyond). The Company's software provider provides
written assurance that its products are Year 2000 compliant on its web site. To
the Company's knowledge, after investigation, no "imbedded technology" (such as
microchips in an electronic control system) of the Company poses a material Year
2000 problem.

     Because the Company believes that it has no material internal Year 2000
problems, the Company has not expended and does not expect to expend a
significant amount of funds to address Year 2000 issues. It is Company policy 

                                       29
<PAGE>

to continue to review its suppliers' Year 2000 compliance and require 
assurance of Year 2000 compliance from new suppliers; however, such 
monitoring does not involve a significant cost to the Company.

     In addition to the foregoing, the Company has contacted its major vendors
and received either oral or written assurances from its major vendors or viewed
assurances contained on vendors' web sites that they have no material Year 2000
problems. The Company believes that its vendors are largely fungible; therefore,
in the event a vendor's representations regarding its Year 2000 compliance were
untrue for any reason, the Company believes that it could find adequate Year
2000 compliant vendors as substitutes.

     The Company is materially dependent on CIG for the delivery of the
Company's gas. CIG has provided the Company with written assurances that a CIG
internal task force has examined CIG's Year 2000 compliance and that CIG has no
material Year 2000 problem.

     In the event that one or more of the Company's vendors were to have a
material Year 2000 problem, the Company believes that the foreseeable
consequences would be a temporary delay in revenue collection caused by an
interruption in computerized billing (and not an interruption in the actual flow
of the Company's coalbed methane), which would not have a substantial long-term
impact on the Company's ability to conduct operations. The Company does not
believe that any contingency planning is necessary to address this possibility.

ITEM 7A.   QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

     The Company measures its exposure to market risk at any point in time by
comparing the open positions to a market risk of fair value. The market prices
the Company uses to determine fair value are based on management's best
estimates, which consider various factors including: Closing exchange prices,
volatility factors and the time value of money. At December 31, 1998, the
Company was exposed to some market risk through interest rates on its long term
debt, foreign currency and natural gas prices. At December 31, 1998, the
Company's exposure to market risk was not material. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations- Hedging
Transactions."

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To the Stockholders and Board of Directors
Evergreen Resources, Inc.
Denver, Colorado

We have audited the accompanying consolidated balance sheets of Evergreen
Resources, Inc. and subsidiaries as of December 31, 1998 and 1997, and the
related consolidated statements of income, stockholders' equity, cash flows, and
comprehensive income for years ended December 31, 1998 and 1997, and the nine
month period ended December 31, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Evergreen Resources,
Inc. and subsidiaries at December 31, 1998 and 1997 and the results of their
operations and their cash flows for the years ended December 31, 1998 and 1997,
and the nine month period ended December 31, 1996 in conformity with generally
accepted accounting principles.

EVERGREEN RESOURCES, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1998 AND 1997 AND THE NINE MONTHS ENDED
DECEMBER 31, 1996


(1)    SUMMARY OF ACCOUNTING POLICIES

BUSINESS

       Evergreen Resources, Inc. ("Evergreen") is an independent energy company
engaged in the exploration, development, production and acquisition of oil and
gas properties. Evergreen's primary focus is on developing coalbed methane
properties located on approximately 200,000 gross acres in the Raton Basin in
southern Colorado. The Company also holds exploration licenses on approximately
500,000 acres onshore in the United Kingdom and an oil and gas exploration
contract on approximately 2.4 million acres in northern Chile.

CONSOLIDATION

       The financial statements include the accounts of Evergreen and its
wholly-owned subsidiaries (the "Company"): Evergreen Operating Corporation
("EOC"), Evergreen Resources (UK) Ltd., Powerbridge, Inc., and Primero Gas
Marketing Company ("Primero").

       The companies are engaged in the operation, acquisition, exploration and
development of oil and gas properties and also the marketing of natural gas. All
significant intercompany balances and transactions have been eliminated in
consolidation.

       The consolidated financial statements also include the Company's 49%
ownership in Maverick Stimulation Company, LLC ("Maverick") and 40% ownership in
Argos Evergreen Limited ("AEL"). The Company accounts for these investments by
the equity method of accounting. All significant intercompany balances and
transactions have been eliminated. Maverick provides pressure pumping and other
oilfield services to the petroleum industry in the Rocky Mountain region.
Maverick provides certain well stimulation services to the Company and during
1998 and 1997 such services amounted to $2,381,400 and $2,636,400, of which
$347,100 and $302,000 was unpaid at year-end. The Company guaranteed
approximately $560,000 of Maverick's outstanding debt at December 31, 1998. The
investment in Maverick, including equity in earnings, was $1,458,500 and
$1,002,300 at December 31, 1998 and 1997. The investment in Maverick is 
included in other assets in the accompanying consolidated financial 
statements. (See Note 14).

CHANGE IN FISCAL YEAR

       Effective with the period ended December 31, 1996, the Company elected to
begin utilizing a December 31 year end. Therefore, the period ended December 31,
1996 represents a nine month short period and the years ended December 31, 1998
and 1997 represent twelve month periods.

FINANCIAL INSTRUMENTS

       The Company's financial instruments that are exposed to concentrations of
credit risk consist primarily of cash equivalents. The Company's cash
equivalents are cash investment funds which are placed with a major financial
institution.

       The Company manages and controls market and credit risk through
established formal internal control procedures which are reviewed on an ongoing
basis. The Company attempts to minimize credit risk exposure to purchasers of
the Company's natural gas through formal credit policies, monitoring procedures
and letters of credit.

       Unless otherwise specified, the Company believes the book value of the
financial instruments approximates their fair value.


                                                                             F-7

USES OF ESTIMATES

       The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
Significant estimates with regard to these financial statements include the
estimate of proved oil and gas reserve volumes and the related present value of
estimated future net cash flows (see supplemental oil and gas disclosures).

PROPERTY AND EQUIPMENT

       The Company follows the full-cost method of accounting for oil and gas
properties. Under this method, all productive and nonproductive costs incurred
in connection with the exploration for and development of oil and gas reserves
are capitalized. Such capitalized costs include lease acquisition, geological
and geophysical work, delay rentals, drilling, completing and equipping oil and
gas wells, including salaries, benefits and other internal costs directly
attributable to these activities. Evergreen capitalized $710,800, $542,200 and
$243,600 of internal costs in 1998, 1997 and 1996. Costs associated with
production and general corporate activities are expensed in the period incurred.
Interest costs related to unproved properties and properties under development
are also capitalized to oil and gas properties. If the net investment in oil and
gas properties exceeds an amount equal to the sum of (1) the standardized
measure of discounted future net cash flows from proved reserves (see Note 15),
and (2) the lower of cost or fair market value of properties in process of
development and unexplored acreage, the excess is charged to expense as
additional depletion. Normal dispositions of oil and gas properties are
accounted for as adjustments of capitalized costs, with no gain or loss
recognized.

       Depreciation and depletion of proved oil and gas properties is computed
on the units-of-production method based upon estimates of proved reserves with
oil and gas being converted to a common unit of measure based on their relative
energy content. Unproved oil and gas properties, including any related
capitalized interest expense, are not amortized, but are assessed for impairment
either individually or on an aggregated basis.

       The costs of certain unevaluated leasehold acreage, wells drilled and
international concession rights are not being amortized. Costs not being
amortized are periodically assessed for possible impairments or reductions in
value. If a reduction in value has occurred, costs being amortized are increased
or a charge is made against earnings for those international operations where a
reserve base is not yet established.

       Gas gathering and support equipment are stated at cost. Depreciation and
amortization for the Raton Basin gas gathering system is computed on the
units-of-production method based upon total reserves of the field. Certain gas
gathering system components and other support equipment are depreciated using
the straight-line method over the estimated useful lives of the assets of 3 to
15 years.

       The Company applies Statement of Financial Accounting Standards ("SFAS")
No. 121, "Accounting for the Impairment of Long-Lived Assets." Under SFAS No.
121, long-lived assets and certain intangibles are reported at the lower of the
carrying amount or their estimated recoverable amounts.


                                                                             F-8
<PAGE>

AMOUNTS PAYABLE TO OIL AND GAS PROPERTY OWNERS

       Amounts payable to oil and gas property owners consist of cash calls from
working interest owners to pay for development costs of properties being
currently developed, production revenue that the Company, as operator, is
collecting and distributing to revenue interest owners and production revenue
taxes that the Company, as operator, has withheld for timely payment to the tax
agencies.

INCOME TAXES

       The Company follows the liability method of accounting for income taxes
under which deferred tax assets and liabilities are recognized for the future
tax consequences. Accordingly, deferred tax liabilities and assets are
determined based on the temporary differences between the financial statement
and tax bases of assets and liabilities, using enacted tax rates in effect for
the year in which the differences are expected to reverse.

ENVIRONMENTAL MATTERS

       Environmental costs are expensed or capitalized depending on their future
economic benefit. Costs that relate to an existing condition caused by past
operations and have no future economic benefit are expensed. Liabilities for
future expenditures of a noncapital nature are recorded when future
environmental expenditures and/or remediation is deemed probable, and the costs
can be reasonably estimated. Costs of future expenditures for environmental
remediation obligations are not discounted to their present value.

GENERAL AND ADMINISTRATIVE EXPENSES

       General and administrative expenses are reported net of amounts allocated
to working interest owners of the oil and gas properties operated by Evergreen,
net amounts charged for administrative and overhead costs, and net of amounts
capitalized pursuant to the full cost method of accounting.

NET INCOME PER SHARE

       The Company applies SFAS No. 128, "Earnings Per Share" for the
calculation of "Basic" and "Diluted" earnings per share. Basic earnings per
share includes no dilution and is computed by dividing income available to
common stockholders by the weighted average number of common shares outstanding
for the period. Diluted earnings per share reflects the potential dilution of
securities that could share in the earnings of an entity.

CASH EQUIVALENTS

       The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents.

MARKET RISK

       The Company measures its exposure to market risk at any point in time by
comparing the open positions to a market risk of fair value. The market prices
the Company uses to determine fair value are based on management's best
estimates, which consider various factors including: Closing exchange prices,
volatility factors and the time value of money. At December 31, 1998, the
Company was exposed to some market risk through interest rates on its long term
debt, foreign currency and natural gas prices. At December 31, 1998, the
Company's exposure to market risk was not considered significant.

HEDGING TRANSACTIONS

       The Company enters into contractual obligations that require future
physical delivery of its natural gas production to attempt to manage price risk
with regard to a portion of its natural gas production. The Company identifies
minimum internal price targets and, assuming other market conditions are deemed
favorable, the Company will enter in hedging contracts to manage price risk.


                                                                             F-9
<PAGE>

STOCK OPTIONS

       The Company applies APB Opinion 25, "Accounting for Stock Issued to
Employees," and related interpretations in accounting for all stock option
plans. Under APB Opinion 25, compensation cost has been recognized for stock
options granted in situations where the option price is less than the market
price of the underlying common stock on the date of grant.

  SFAS No. 123, "Accounting for Stock-Based Compensation," requires the Company
to provide pro forma information regarding net income as if compensation cost
for the Company's stock option plans had been determined in accordance with the
fair value based method prescribed in SFAS No. 123. To provide the required pro
forma information, the Company estimates the fair value of each stock option at
the grant date by using the Black-Scholes option-pricing model.

FOREIGN CURRENCY TRANSLATION

       The functional currency for the Company's foreign operations is the
applicable local currency. The translation of the applicable foreign currency
into U.S. dollars is performed for balance sheet accounts using current exchange
rates in effect at the balance sheet date and for revenue and expense accounts
using a weighted average exchange rate during the period. The gains or losses
resulting from such translation are included in stockholders' equity.

RECLASSIFICATIONS

       Certain items included in prior years' financial statements have been
reclassified to conform to current year presentation.

COMPREHENSIVE INCOME

       During 1998, the Company adopted SFAS No. 130, "Reporting Comprehensive
Income." The implementation of SFAS No. 130 required comparative information for
earlier years to be restated. The Company has elected to report comprehensive
income in a consolidated statement of comprehensive income. Comprehensive income
is comprised of net income and all changes to stockholders' equity, except those
due to investments by stockholders, changes in paid-in capital and distributions
to stockholders.

RECENT ACCOUNTING PRONOUNCEMENTS

       In June 1998, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities"
which establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts and for
hedging activities. SFAS No. 133 is effective for all fiscal quarters of fiscal
years beginning after June 15, 1999. Management believes the adoption of this
statement will not have a material impact on the Company's financial statements.

(2)    ACCOUNTS RECEIVABLE

       The components of accounts receivable include the following:

</TABLE>


       Oil and gas property costs of $25,567,400 were not being amortized at
December 31, 1998. These costs consisted of $14,947,500 for domestic properties,
$8,504,700 for the United Kingdom ("U.K."), $1,520,200 for the Falkland Islands
and $595,000 for Chile. The Company will classify the unevaluated costs for the
U.K., Falkland Islands and Chile as evaluated costs when future development of
the Current Licenses determines the viability of the underlying reserves. The
Company anticipates that substantially all of the unevaluated costs related to
domestic properties will be classified as evaluated costs within the next three
to five years.

       On July 2, 1998, Evergreen completed the acquisition of approximately
27,000 acres in the Raton Basin and 28 existing wells and related gathering
facilities for cash of $13 million. Effective December 31, 1998, the Company
acquired an additional 41,000 gross acres in the Raton Basin and 17 producing
wells for stock valued at $7.5 million, the assumption of approximately $750,000
in debt and $250,000 in cash. The aggregate amount of the purchase price
allocated to proved properties was $9 million, unproved properties was $11.6 
million and gas gathering equipment $1 million.

       The Company is in the process of developing properties in the U.K. and is
unable to prepare reserve information in this area. In 1997, under a new onshore
licensing regime implemented by the U.K. Department of Trade and Industry,
Evergreen converted its Original Licenses to new onshore Licenses, called
Petroleum Exploration and Development Licenses (the "Current Licenses"). In
connection with such conversion, the Company relinquished rights to
approximately 259,000 acres, which were not considered highly prospective for
coalbed methane development. Under the Current Licenses, the Company retains
approximately 377,000 acres, which were high-graded for coalbed methane and
conventional hydrocarbon potential. Subsequent to year-end, the Company acquired
an additional 136,000 acres. The total acreage in the U.K. is approximately
513,000 acres. The Current Licenses provide up to a 30 year term with optional
periodic relinquishment of portions of the license, subject to future
development plans. There are no royalties or burdens encumbering these Current
Licenses. Work commitments for acreage retained will include remote sensing
studies, additional seismic studies and the drilling of three wells in 1999.
Work commitments on the Current Licenses have been fulfilled through 1998 as a
result of ERI's prior U.K. activity. The Company has completed a new seismic
program to identify a new seven-well drilling project. The drilling project is
scheduled for mid to late 1999.


                                                                            F-11
<PAGE>

       Evergreen has a net 2% interest in a Falkland Islands consortium, which
has drilled two wells in the North Falklands Basin. Both wells have been plugged
and abandoned as dry holes with oil shows. The abandonment of the wells
completes the initial drilling campaign on Tranche A. The two wells on Tranche A
have established good source rocks and potential reservoir rocks. The consortium
will assess the data gathered from the two wells to determine the future
strategy for the acreage. See Note 13 regarding the Chilean oil and gas 
exploration contract.

       Included in construction in progress at December 31, 1998, are costs 
for a new compressor station, gas gathering laterals, costs for well 
equipment and well service equipment. The Company estimates that it will 
spend an additional $6.9 million to complete these projects.

(4)    FINANCING AGREEMENT

       The Company currently has a $50 million revolving line of credit with 
a bank group consisting of Hibernia National Bank, as agent, Chase Bank of 
Texas and Paribas (the "Banks"). The line is available through June 2001. 
Advances pursuant to this line of credit are limited to a borrowing base, 
which is presently $50 million. At the Company's election, it may use either 
the London interbank offered rate ("Libor") plus a margin of 1.38% to 1.75% 
or the prime rate plus a margin of 0% to .25%, with margins on both rates 
determined on the average outstanding borrowings under the credit facility. 
The Company's average interest rate at December 31, 1998 was 6.87%. The 
borrowing base is redetermined semi-annually by the Banks based upon reserve 
evaluations of the Company's oil and gas properties. The current borrowing 
base is less than the total borrowing base that could have been requested 
under the terms of the agreement. An average annual facility fee of .375% is 
charged quarterly for any unused portion of the credit line. The agreement is 
collateralized by oil and gas properties and also contains certain net worth 
and ratio requirements. At December 31, 1998 and 1997, $44,138,700 and 
$10,812,000 was outstanding under the line of credit. Subsequent to year-end, 
the Company increased its line of credit to $75 million with the same terms 
and conditions as the current line of credit.

(5)    CAPITAL LEASE OBLIGATIONS

       The Company has capital equipment leases with a bank with interest at 
8.5% at December 31, 1998 for a term of five years, including options to 
purchase the equipment at a nominal amount at the end of the lease term. The 
Company primarily leases compressors for the Raton Basin gas gathering system 
and other related production equipment.

       Future minimum lease payments are as follows:

(6)    DESIGNATED CASH AND RELATED PRODUCTION TAXES PAYABLE

       Designated cash represents the cash withheld for payment of production
taxes from the Company and third party revenue interest owners. The production
taxes payable relates to ad valorem taxes collected for production through
December 1998 which are not payable until fiscal 2000 or later. The related cash
collected from the Company and third party revenue interest owners designated
for payment of ad valorem taxes is reflected as a non-current asset.

       For the nine months ended December 31, 1996, common stock equivalents of
1,136,430, were not included in the computation of diluted earnings per share
because their effect was antidilutive. For the years ended December 31, 1998 and
1997, all common stock equivalents were included in the computation of diluted

OTHER EQUITY TRANSACTIONS

       On August 1, 1996, the Company acquired the limited partnership interests
of Energy Investors Fund, LP and Energy Investors Fund II, LP in PBI Fuels, LP
and 100% of the common stock of Powerbridge Inc. for a purchase price of $11.3
million. The purchase price was comprised of 1,162,266 shares of restricted
common stock valued at $7.7 million and the assumption of $3.6 million of
long-term debt.


                                                                            F-14

       On October 28, 1996, the Company completed a public offering of its
common shares, whereby it sold 2,000,000 shares at $5.75 per share. Proceeds,
net of underwriters' commissions and their expenses of $1,253,200, were
$10,246,800.

       During the year and nine months ended December 31, 1997 and 1996, the
Company issued common stock valued at $239,900 and $86,400 as a bonus to certain
employees.

       On July 7, 1997, the Board of Directors adopted a Shareholder Rights 
Plan ("Rights Plan"), pursuant to which stock purchase rights (the "Rights") 
were distributed as a dividend to the Company's common stockholders at a rate 
of one Right for each share of common stock held of record as of July 22, 
1997. The Rights Plan is designed to enhance the Board's ability to prevent 
an acquirer from depriving stockholders of the long-term value of their 
investment and to protect shareholders against attempts to acquire the 
Company by means of unfair or abusive takeover tactics that have been 
prevalent in many unsolicited takeover attempts. Under the Rights Plan, the 
Rights will become exercisable only if a person or a group (except for 
existing 20% shareholders) acquires or commences a tender offer for 20% or 
more of the Company's common stock. Until they become exercisable, the Rights 
attach to and trade with the Company's common stock. The Rights will expire 
July 22, 2007. The Rights may be redeemed by the continuing members of the 
Board at $.001 per Right prior to the day after a person or group has 
accumulated 20% or more of the Company's common stock.

       During the year ended December 31, 1997, pursuant to the exercise of
stock purchase warrants, 30,900 shares of common stock were issued at $3.63, in
exchange for 7,677 shares of common stock currently issued and outstanding at
various market values. In addition, 58,446 shares of common stock were issued
under terms of warrants previously granted, resulting in proceeds to the Company
of $367,300.

       For the year ended December 31, 1998, the Company issued common stock to
directors for directors fees and stock to certain employees for compensation
valued at $190,000.

       During 1998, pursuant to the exercise of stock purchase warrants, 276,555
shares of common stock were issued under terms of warrants previously granted,
resulting in net proceeds to the Company of $2,184,300.

       Effective December 31, 1998, the Company purchased the coalbed methane 
gas interests from a Company for $8.5 million. The purchase price consisted 
of 450,000 shares of Evergreen common stock valued at $16.67 per share for a 
total of $7.5 million and the assumption of $750,000 in debt and cash of 
$250,000. This acquisition is discussed further in Note 3.

(10)   STOCK OPTIONS

       On May 12, 1997, the Board of Directors adopted, and the Company's
shareholders subsequently approved, an Initial Stock Option Plan (the "Plan"),
whereby employees may be granted incentive options to purchase up to 500,000
shares of the common stock of the Company. The exercise price of incentive
options must be equal to at least the fair market value of the common stock as
of the date of grant. In January 1998, the Company granted 185,000 options under
the Plan.

       Under the terms of its Key Employee Equity Plan, options and/or warrants
are granted to key employees at not less than the market price of the Company's
common stock on the date of grant. However, during 1998, the Board of Directors
and the shareholders approved the issuance of warrants for 79,990 shares of the
Company's common stock to officers and directors at an exercise price of $7.00.
The market price for the stock was $13.00 at the time of the grant. The value of
these options was $478,764 of which $224,600 was recorded as current year
compensation expense. The purpose of the warrants was to reward directors and
key personnel for past performance and to give them an incentive to remain with
the Company and to induce directors to take all or part of their non-executive
directors' compensation in the form of common stock. During the year ended
December 31, 1997, the Company granted 145,000 warrants at exercise prices
ranging from $8.75 to $9.88. During the nine months ended


                                                                            F-15
<PAGE>

December 31, 1996, the Company granted 405,001 warrants to officers and
directors at exercise prices ranging from $5.75 to $7.00. In connection with the
1996 public offering, the Company issued 200,000 warrants to the underwriters at
an exercise price of $6.90 per share. The presently outstanding options and
warrants expire in 2000 to 2005.

       SFAS No. 123, "Accounting for Stock-Based Compensation," requires the
Company to provide pro forma information regarding net income and net income per
share as if compensation costs for the Company's stock option plans and other
stock awards had been determined in accordance with the fair value based method
prescribed in SFAS No. 123. The Company estimated the fair value of each stock
award at the grant date by using the Black-Scholes option-pricing model with the
following weighted-average assumptions used for grants in the nine months ended
December 31, 1996: dividend yield of 0 percent for all years; expected
volatility of 9 percent; risk-free interest rate of 6.6 percent; and expected

       See Notes 1, 3, 5, 8, 9, 10, and 13 for additional noncash
transactions during the years ended December 31, 1998 and 1997 and the nine 
months ended December 31, 1996.

(13)   COMMITMENTS AND CONTINGENCIES

       In August 1997, the Company entered into an agreement with Colorado
Interstate Gas ("CIG") pursuant to which CIG built a new, 115-mile, 16-inch
pipeline (the "Campo Lateral"). This agreement has a term of 15 years and
entitles the Company to firm transportation of its Raton Basin gas from the
field to the CIG interconnection with other interstate pipelines in Texas. The
Company committed to transport natural gas from the Raton Basin through CIG's
pipelines commencing September 1998. The initial commitment is 25 MMcf per day,
increasing every six months to a maximum of 41 MMcf per day 18 months after
commencement. Subject to available capacity in the pipeline, the Company has the
first right to increase its volumes up to 100 MMcf per day. The Company expects
to meet its volume obligations with respect to the Raton Basin transportation
agreement. If the Company is unable to meet its firm transportation commitments,
the commitment must be paid for but can be deferred and utilized at a later
date.

       During 1998, the Company acquired certain properties in the Raton Basin.
In addition to the properties, the Company assumed firm transportation
commitments with CIG. The total transportation commitments are 12 MMcf per day,
with 6 MMcf per day expiring in 2004 and 6 MMcf per day expiring 2012.

       Under terms of the transportation agreements, the Company has committed
to pay the following transportation reservation charges with CIG to provide firm
transportation capacity rights:

       In May 1998, the Company entered into a new ten-year office lease for
approximately $267,500 per year. Rental expense, net of sublease income, was
approximately $234,000, $138,000, and $99,900, for the years and nine months
ended December 31, 1998, 1997 and 1996.

       On January 19, 1998, the Company submitted an application to the Internal
Revenue Service to terminate the Employee Stock Ownership Plan ("ESOP"). For the
nine months ended December 31, 1996, the Company contributed $28,000 to the
plan. There were no contributions to the plan for the years ended December 31,
1998 and 1997.


                                                                            F-18
<PAGE>

       Effective January 1, 1997, the Company implemented a 401(k) plan ("the
"Plan") for all eligible employees. The Company provides a matching contribution
up to a certain percentage of the employees contributions. The Plan also
provides for a profit sharing contribution determined at the discretion of the
Company. The total matching contributions and profit sharing contribution for
the years ended December 31, 1998 and 1997 were approximately $33,600 and
$134,000.

       In August 1992, the Company entered into a series of agreements with El
Paso Field Services Company ("El Paso Services") concerning the connection of
Evergreen's San Juan Basin wells to El Paso's non-jurisdictional gathering
system. Under the terms of certain gas gathering and tie-in agreements, EOC was
committed to meeting certain minimum volume levels during the term of the
agreement. As of September 30, 1997 and December 31, 1996, the volume levels
were below the required minimums and EOC accrued approximately $2,431,000 and
$2,231,000 for this shortfall, which was included with long-term liabilities.
The Company's cumulative delivery shortfall through September 30, 1997 was
approximately 12.1 million MMbtu. Effective October 1, 1997, the Company sold
all of its San Juan Basin properties for $580,000 along with the assumption of
EOC's volume commitment to El Paso Services. As of October 1, 1997, the Company
eliminated the obligation to El Paso Services.

       The Company is a guarantor of a line of credit and a capital lease for
Maverick for an aggregate amount of $1.5 million. The guaranteed obligations
amounted to $560,000 at December 31, 1998.  (See Note 14).

       In connection with the Chilean oil and gas exploration contract, the
Company will be required to spend approximately $1.5 million for a seismic
program during the years 1999 and 2000. In connection with the 1999 and 2000
commitments, the Company has issued letters of credit totaling $1.5 million
which expire in June 2000.

       On July 13, 1998, Southern Colorado C.U.R.E. filed a lawsuit under the 
citizen suit provision of the Clean Water Act in the U.S. District Court for 
the District of Colorado against EOC, related to its coalbed methane drilling 
operations in the Raton Basin near Trinidad, Colorado. The Company's gas 
production produces naturally occurring groundwater as a by-product of its 
coalbed methane gas production operations. The storage, use, and disposal of 
the produced groundwater in evaporative ponds and natural collection features 
located on the surface at or near the wellsite, and the legal and regulatory 
treatment of this practice, underlie the lawsuit. EOC is also subject to 
federal, state and local environmental laws and regulations and is currently 
participating with the EPA and the State of Colorado in the investigation of 
certain practices in connection with these operations. An evaluation of costs 
of potential liabilities associated with this investigation cannot be 
reasonably determined at this time. The Company does not expect that the 
lawsuit or the investigation or the environmental costs or contingent 
liabilities of either, if any, will have a material adverse effect on its 
consolidated financial position or its results of operations.

As of December 31, 1998, the Company had entered into contracts to sell
approximately 10,000 MMBtu per day through October 31, 1999 at a fixed price of
$1.61 per Mcf.

(14)   SUBSEQUENT EVENTS

       On February 18, 1999, the Company sold its 49% interest in Maverick to
 the managing members of Maverick for cash of approximately $2.25 million. The
 expected closing date is April 1999. The Company will also upon closing, be 
 released from its guarantee of the Maverick debt.

       Through March 1999, EOC operated properties for various third party
 working interest owners. In January 1999, the working interest owners sold
 those properties. As of April 1, 1999, EOC will no longer receive overhead
 charges for the operation of those properties.


                                                                            F-19

OIL AND GAS RESERVES (UNAUDITED)

       The estimates of the Company's proved reserves and related future net
cash flows that are presented in the following tables are based upon estimates
made by independent petroleum engineering consultants for the United States
only.

       The Company's reserve information was prepared as of December 31, 1998,
1997 and 1996. The Company cautions that there are many inherent uncertainties
in estimating proved reserve quantities, projecting future production rates, and
timing of development expenditures. Accordingly, these estimates are likely to
change as future information becomes available. Proved oil and gas reserves are
the estimated quantities of crude oil, condensate, natural gas and natural gas
liquids which geological and engineering data demonstrate with reasonable
certainty to be recoverable in future years from known reservoirs under existing
economic and operating conditions. Proved developed reserves are those reserves
expected to be recovered through existing wells, with existing equipment and
operating methods.

       Estimated quantities of proved reserves and proved developed reserves of
crude oil and natural gas (all of which are located within the United States),
as well as the changes in proved reserves, are as follows:

       The following table sets forth a standardized measure of the estimated
discounted future net cash flows attributable to the Company's proved oil and
gas reserves. Gas prices have fluctuated widely in recent years. The calculated
weighted average sales prices utilized for the purposes of estimating the
Company's proved reserves and future net revenues were $1.60, $1.87 and $1.61
per Mcf of gas at December 31, 1998, 1997 and 1996. The future production and
development costs represent the estimated future expenditures to be incurred in
developing and producing the proved reserves, assuming continuation of existing
economic conditions. Future income tax expense was computed by applying
statutory income tax rates to the difference between pretax net cash flows
relating to the Company's proved oil and gas reserves and the tax basis of
proved oil and gas properties and available operating loss and excess statutory
depletion carryovers.

                                PRELIMINARY STATEMENT

     WHEREAS, the Borrower and Hibernia National Bank (the "Initial Bank") 
entered into an Amended and Restated Credit Agreement dated as of June 1, 
1997 (the "Prior Credit Agreement"), which in turn was a renewal, increase,

dated as of November 15, 1990, as amended by that certain letter agreement 
dated December 30, 1991, by that certain Second Amendment to Credit Agreement 
dated as of February 5, 1993, by that certain letter agreement dated February 
11, 1993, by that certain Note Modification Agreement dated as of February 
28, 1995, by that certain Note Modification Agreement dated as of March 31, 
1995, by that certain Sixth Amendment to Credit Agreement dated as of April

     NOW, THEREFORE, in consideration of the premises, and the mutual

                                   ARTICLE I

                                 GENERAL TERMS

     Section 1.1 TERMS DEFINED ABOVE. As Used in this Agreement, the terms 
"Agent", " Agreement", "Banks", "Borrower", "Initial Bank" and "Prior Credit 
Agreement" shall have the meanings indicated above. 

<PAGE>

                                       2

     Section 1.2 CERTAIN DEFINITIONS. As used in this Agreement, the 
following terms shall have the meanings indicated (and as indicated by 
Section 9.14), unless the context requires a different meaning:

     "ADVANCES" shall mean the borrowings on the Closing Date under the Loan and
     all or any portion of such borrowings and reborrowings under the Loan so
     long as same remain outstanding and unpaid.

     "AMOUNT" shall mean fifty million ($50,000,000.00) dollars.

     "BORROWING BASE" shall mean, at any particular date, the dollar amount
     calculated as the loan value of the Collateral as determined by the Agent
     in its sole and absolute discretion based upon the Agent's customary
     standards and practices from time to time in effect with respect to secured
     oil and gas property lines, but with the consent of all the Banks as
     provided below in this definition. Any good faith determination by the
     Agent of the Borrowing Base shall be final and conclusive as to the
     Borrower. The Borrowing Base may be revised by Agent at any time to reflect
     changes in the Collateral or the occurrence of events or economic
     conditions or otherwise pursuant to Agent's customary standards and
     practices as such exist at that particular time, and further will be
     subject to scheduled semi-annual re-determinations during the term of this
     Loan (currently scheduled on or before April 30 and October 30 of each
     year). Each Borrowing Base determination of amortization/scheduled values
     over time shall be effective until redetermined by the Agent in accordance
     with this Agreement (or until the Maturity Date). Such redetermination by
     the Agent may lead to increased or decreased credit availability to the
     Borrower under the revised Borrowing Base schedule. The Agent shall give
     the Borrower written notice of each redetermined Borrowing Base schedule at
     least fifteen (15) days before such new Borrowing Base schedule is to
     become effective. Without limiting the Agent's discretion, the Agent may
     exclude, in its sole and absolute discretion, any property or portion of
     production therefrom from the Borrowing Base, at any time, because title
     information on, or the status of title to, such 

<PAGE>

                                       3

     property is not reasonably satisfactory to Agent, such property is not
     Collateral, the Agent's lien or security interest therein is not first and
     prior to all others, or such property is not assignable. As of the Closing
     Date, the Borrowing Base is $50,000,000.00. Thereafter, the Agent shall
     make a preliminary re-determination of the Borrowing Base each April 30 and
     October 30 of each year (assuming timely delivery of requested information
     from the Borrower), and otherwise at such times as deemed appropriate by
     the Agent or the Required Banks (and as required by Section 3.3). The Agent
     promptly shall notify the Banks in writing of each such preliminary
     re-determination. Any Bank which has not notified the Agent in writing of
     its disapproval of any such preliminary re-determination of the Borrowing
     Base within ten (10) days of its receipt of such notice shall be deemed to
     have approved of such re-determination. Each re-determination of the
     Borrowing Base (increase or decrease) shall require the consent of all of
     the Banks. Upon approval of all the Banks of each redetermination, the
     Agent shall notify the Borrower as provided above.

     "BUSINESS DAY" shall mean (a) for all purposes other than as covered by

     Interest Period occurs on a day of an initial calendar month for  which
     there is no numerically corresponding day in the calendar month that

     Interest Period, such Interest Period shall end on the last Business Day of
     such succeeding calendar month; and (iv) if the Borrower fails to designate
     an Interest Period, the Interest Period for a LIBO Rate Advance
     (recognizing that under Subsection 2.l(b) below the Banks are not
     obligated to make such a LIBO Rate Advance in the absence of such
     designation by the Borrower) shall be deemed to be one month until a
     different designation is made for a subsequent Interest Period. No Interest
     Period for a LIBO Rate Advance shall have a duration of less than one
     month, and if any such Interest Period would otherwise be a shorter period,
     the relevant Advance shall be a Prime Rate Advance during such period. The

     the Borrower or other Person, the Prime Rate shall change automatically
     from time to time as and in the amount by which said Citibank Prime shall
     fluctuate, with each such change in the Prime Rate to be effective as of
     the date of each change in such Citibank Prime. Citibank Prime is a
     reference rate and does not necessarily represent the lowest or best rate
     actually charged to any customer by Citibank or by the Agent or any Bank.
     The "APPLICABLE PRIME RATE MARGIN" shall mean the following per annum
     interest rate from time to time, determined for any fiscal quarter by
     reference to the Percentage Outstanding during the immediately prior fiscal
     quarter, in accordance with the following schedule:

     The Applicable Prime Rate Margin shall remain fixed during each fiscal
     quarter of Borrower's fiscal year, determined on the first day of each
     fiscal quarter depending upon the Percentage Outstanding for the
     immediately prior quarter. (During the first quarter of this Agreement,
     commencing July 1, 1998, the Applicable Prime Rate Margin shall be zero
     (0.00%) percent.) The Prime Rate shall be adjustable on a daily basis to
     reflect any changes in Citibank Prime, and further adjusted on a quarterly
     basis on the first day of each quarter to reflect any changes in the
     Applicable Prime Rate Margin.

     "PRIMERO" shall mean Primero Gas Marketing Company, a Colorado joint
     venture.

     "REQUIRED BANKS" shall mean Banks in the aggregate holding at least
     sixty-six and two-thirds (66 2/3%) percent of the aggregate unpaid

     "SUBSIDIARIES" shall mean at any date with respect to the Borrower (i) all
     the corporations of which the Borrower at such date, directly or
     indirectly, owns fifty (50%) percent or more of the outstanding capital
     stock (excluding directors' qualifying shares), and (ii) all the
     partnerships, limited liability companies or other Persons of which the
     Borrower at such date, directly or indirectly, owns fifty (50%) percent or
     more of the outstanding partnership, membership or other ownership or
     voting interest.

accounting terms used herein shall be interpreted, all accounting determinations
hereunder shall be made, and all financial statements required to be delivered

                                    THE CREDIT

     Section 2.1 LINE OF CREDIT (INCLUDING STANDBY LETTERS OF CREDIT). (a) 
LINE. Subject to and upon the terms and conditions contained in this 
Agreement, and relying on the representations and warranties contained in 
this Agreement, each Bank, severally, agrees to make a revolving line of 
credit available to the Borrower in the maximum aggregate principal amount 
equal to such Bank's Commitment set forth in SCHEDULE 1 hereto. The aggregate 
amount of all Advances, plus the undisbursed amount of all standby letters of 
credit permitted to be issued under Subsection 2.1(c) hereof, cannot exceed 
the Commitment Limit. The line of credit is represented by the Notes in the 
aggregate principal amount of the Amount, and individually in the principal 
amount of each Bank's commitment, payable to the order of the Banks. 
Principal and all accrued and unpaid interest on the line of credit shall be 
payable in full at maturity on the Maturity Date, after which no further 
Advances will be made.

     (b) INTEREST. The interest rate applicable to each Loan Advance 
beginning on the date such Advance is made shall be either (i) the Prime 
Rate, adjusted daily, or (ii) the LIBO Rate, adjusted on the first day of 
each LIBO Rate Interest Period and remaining fixed for the duration of the 
LIBO Rate Interest Period, selected at the Borrower's option by written 
notice to Agent in accordance with the terms hereof. Effective on the first 
day following the end of any LIBO Rate Interest Period, the Borrower may from 
time to time change the interest rate which is to apply to the Advances or a 
portion thereof (including any yet to be made Advance which is made on the 
effective date of the interest rate change) by notifying the Agent of the 
Borrower's desire to change the interest rate not less than three (3) 
Business Days prior to the date on which such change shall be effective. No 
more than four (4) LIBO Rate tranches and one Prime Rate tranche (all Prime 
Rate Advances constituting one tranche) shall be permitted for the Loan at 
any one time. In the absence of any timely specific interest rate election by 
the Borrower (as provided above in this Subsection 2.1(b) and in the 
definition of LIBO Rate), unless otherwise agreed by the Agent and all the 
Banks, an Advance (if outstanding as a LIBO Rate Advance) will be 
automatically converted into a Prime Rate Advance on the last day of the then 
current Interest Period for such Advance or (if not then outstanding) an 
Advance shall bear interest at the Prime Rate. The Borrower further will 
comply with the provisions of ADDENDUM I hereto, relating to the LIBO Rate, 
which is an integral part of this Agreement. Interest shall be payable (x) on 
Advances bearing interest at the Prime Rate monthly in arrears on the last 
day of each month, beginning July 31, 1998, and (y) on LIBO Rate Advances on 
the last day of each applicable Interest Period for each LIBO 

<PAGE>

                                       14

Rate Advance. Payments may be debited from the Borrower's accounts at the 
Agent as provided in this Agreement.

     (c)  LETTERS OF CREDIT. As a portion of the line of credit availability 
(and subject to the Borrowing Base and the other terms and conditions 
contained in this Agreement), the Initial Bank will issue standby letters of 
credit for the account of the Borrower (or any one or more of the Borrower's 
wholly-owned Subsidiaries from time to time in existence, including Evergreen 
Operating Company and Primero, so long as such entity is wholly-owned 
directly or indirectly) from time to time. The expiration of such letters of 
credit shall be on a Business Day not later than one year after issuance, and 
further shall not extend beyond the Maturity Date of the line of credit. The 
Borrower shall pay to the Agent, for disbursement in accordance with Section 
9.1(a), a fee for each standby letter of credit in advance on the issuance 
date at the per annum rate of seven-eighths of one percent (0.875%) on the 
face amount of the letter of credit for the period from the date of issuance 
to the expiration date, plus the Borrower shall pay to the Agent, for the 
account solely of the Initial Bank, additional amounts customarily charged by 
the Initial Bank for the issuance and processing of letters of credit. Each 
letter of credit shall be issued not later than the close of the Initial 
Bank's business (Central Time) on the third (3rd) Business Day after receipt 
(including by facsimile pursuant to Section 10.1 hereof) by the Initial Bank 
of the Borrower's written application in substantially the form of the 
Initial Bank's then standard Application for Irrevocable Standby Letter of 
Credit and Letter of Credit Agreement, executed by the Borrower (by any one 
of the persons designated by the Borrower in writing to the Agent in 
accordance with the terms of Subsection 2.1(d) below). Such application and 
agreement shall be Collateral Documents under this Agreement, supplemental to 
and not in replacement of this Agreement and the other Collateral Documents, 
provided that in the event of a conflict between such application and 
agreement and this Agreement then this Agreement shall prevail (even if such 
application or agreement is executed later). In the event such written 
application is telecopied to the Initial Bank, the Initial Bank may but need 
not confirm such application before acting thereupon. The Initial Bank may 
rely fully and completely upon the authority of the signatory of such written 
application and the contents thereof unless such authority is terminated by 
written notice to the Initial Bank, and any such termination of authority 
shall be effective only prospectively. Such letters of credit will be 
documented on the Initial Bank's standard forms. No letter of credit will be 
issued if the face amount thereof plus the aggregate of all Advances then 
outstanding plus the aggregate undisbursed amount of all standby letters of 
credit then outstanding would exceed the Commitment Limit. Payment by the 
Initial Bank of a draw on a standby letter of credit, if not reimbursed in 
full on the same day by the Borrower, automatically (notwithstanding the 
limitation in Subsection 2.1(a) above) shall be an Advance as a part of the 
Loan bearing interest from the date of such draw at the Prime Rate. 

<PAGE>

                                       15

Upon its issuance of any such letter of credit, the Initial Bank shall 
promptly notify each other Bank of such issuance. Immediately upon the 
issuance by the Initial Bank of any letter of credit, the Initial Bank shall 
be deemed to have sold and transferred to each other Bank and each such other 
Bank shall be deemed irrevocably and unconditionally to have purchased and 
received from the Initial Bank, without recourse or warranty, an undivided 
interest and participation in such letter of credit, each drawing made 
thereunder and the obligations of the Borrower under this Agreement with 
respect thereto, and any security therefor or guaranty pertaining thereto. 
The amount of such other Bank's participation shall be such other Bank's 
prorata portion (i.e., such Bank's Commitment as compared to the aggregate of 
the Commitments).

     In the event that the Initial Bank makes any payment under any letter of 
credit and the Borrower shall not have reimbursed such amount in full to the 
Initial Bank on the date of such payment, the Initial Bank shall promptly 
notify the Agent, which shall promptly notify each other Bank of such 
failure, and each other Bank shall promptly and unconditionally pay to the 
Initial Bank the amount of such other Bank's prorata portion (i.e., such 
Bank's Commitment as compared to the aggregate of the Commitments) of such 
unreimbursed payment in immediately available funds. If the Agent so 
notifies, prior to 11:00 a.m. (Central Time) on any Business Day, each 
Participant shall make such payment on such Business Day. The failure or 
refusal by any Bank to make reimbursement to the Initial Bank at the 
aforesaid time and place in the amount of its portion of such reimbursement 
shall not relieve any other Bank from its several obligation hereunder to 
make reimbursement to the Initial Bank in the amount of such other Banks 
portion of such requested reimbursement (but no Bank shall be responsible for 
the failure of any Bank to make reimbursement to the Initial Bank of such 
other Bank's portion of such requested reimbursement). If any Bank makes 
reimbursement to the Initial Bank of such amount on a date after the 
aforesaid date for reimbursement, such Bank shall pay to the Initial Bank on 
demand an amount computed on the basis set forth in Subsection 2.1(f) below 
(substituting such reimbursement due date for the Advance Date), which 
Subsection 2.1(f) shall be fully applicable to such failure.

     The obligations of the other Banks to make reimbursement payments to the 
Initial Bank with respect to letters of credit issued by it shall be 
irrevocable and not subject to any qualification or exception whatsoever. In 
determining whether to pay under any letter of credit, the Initial Bank shall 
have no obligation relative to the other Banks other than to confirm that any 
documents required to be delivered under such Letter of Credit appear to have 
been delivered and that they appear to comply on their face with the 
requirements of such letter of credit. Any action taken or omitted to be 
taken by the Initial Bank under or in connection with any letter of credit if 
taken or omitted in the absence of gross negligence or 

<PAGE>

                                       16

willful misconduct shall not create for the Initial Bank any resulting 
liability to the Borrower or any Bank.

     (d)  REQUESTS. The Banks will make Advances to the Borrower from time to 
time on any Business Day in such amounts as the Borrower may have timely 
requested as provided in Subsection 2.1(e) up to the maximum amount provided 
in Subsection 2.1(a) above, and the Borrower may make borrowings, repayments 
and reborrowings in respect thereof. Requests for Advances must be made by 
the Borrower in writing to the Agent, by either certified or registered mail 
or by facsimile transmission in accordance with Section 10.1, the number of 
days before the Business Day for the Advance as provided in Subsection 2.1 
(e). Such request shall be fully authorized by the Borrower if made by any 
one of the persons hereby designated by the Borrower as an authorized person: 
the President of Borrower or any other officer of the Borrower designated by 
the President in writing to the Agent in accordance with resolutions of the 
Board of Directors of the Borrower certified to the Agent. The Agent and the 
Banks may rely fully and completely upon the authority of the signatory of 
such request unless such authority is terminated by written notice to Agent, 
and any such termination shall be effective only prospectively. The credit 
advice resulting from the deposit of the proceeds of any disbursement in the 
Borrower's account with the Agent or the Agent's copy of any cashier's check 
representing all or any part of the proceeds of the disbursement shall be 
deemed prima facie evidence of the Borrower's Indebtedness to the Banks on 
the line of credit.

     (e)  TIMING. Requests for Advances at the Prime Rate shall be made on 
written notice from the Borrower to the Agent, received by the Agent no later 
than 10:00 a.m. (Central Time) on the Business Day of such Prime Rate Advance 
specifying the amount thereof. Request for Advances at the LIB0 Rate shall be 
made on written notice from the Borrower to the Agent received by the Agent 
no later than 11:00 a.m. (Central Time) on the third (3rd) Business Day 
before such LIBO Rate Advance, specifying the amount thereof (including the 
amount of each Tranche, if more than one) and the LIBO Interest Period (or 
interest Periods, if more than one tranche). Each such written notice by the 
Borrower shall be irrevocable by the Borrower. The request for any Advance 
shall constitute a certification by the Borrower that all of the 
representations and warranties contained in Article 4 (other than those 
representations and warranties, if any, that are, by their specific terms, 
limited in application to a specific date) arc true and correct as of the 
date of such request and also as of the date of the Advance. The Agent shall 
promptly give each Bank notice of such proposed Advance. 

<PAGE>

                                       17

     (f)  FUNDING. Not later than 12:00 noon (Central Time) on the date of 
any Advance, each of the Banks shall make available to the Agent, in 
immediately available funds, the amount of such Bank's prorata portion (i.e., 
the percentage of its Commitment as compared to the aggregate of the 
Commitments) of the amount of the requested Advance. Upon receipt from each 
Bank of such amount, and upon fulfillment of the applicable conditions set 
forth in this Agreement in Article 7, the Agent (on behalf of the Banks) will 
make available to the Borrower the aggregate amount of such Advance in 
accordance with the further terms of this Section 2.1. The failure or refusal 
of any Bank to make available to the Agent at the aforesaid time and place on 
any date of an Advance the amount of its portion of the requested Advance 
shall not relieve any other Bank from its several obligation hereunder to 
make available to the Agent the amount of such other Bank's portion of any 
requested Advance (but no Bank shall be responsible for the failure of any 
Bank to make available to the Agent such other Bank's portion of any 
requested Advance).

     The Agent may, unless notified to the contrary by any Bank prior to the 
date of an Advance, assume that each Bank has made available to the Agent on 
such date of the applicable Advance the amount of each Bank's portion of the 
Advance to be made on such date, and the Agent shall, in reliance upon such 
assumption, make available to Borrower a corresponding amount. If any Bank 
makes available to the Agent such amount on a date after the date of the 
applicable Advance, such Bank shall pay to the Agent on demand an amount 
equal to the product of (i) the average computed for the period referred to 
in clause (iii) below, of the weighted average interest rate paid by the 
Agent for federal funds acquired by the Agent during each day included in 
such period, TIMES (ii) the amount of such Bank's portion of such Advance, 
TIMES (iii) a fraction, the numerator of which is the number of days that 
elapse from and including such date of the Advance to the date on which the 
amount of such Bank's portion of such Advance shall become immediately 
available to the Agent, and the denominator of which is 365; PROVIDED, that 
if such Bank has not paid to the Agent such Bank's portion of the Advance by 
12:00 noon (Central Time) on the third (3rd) Business Day after the Advance 
was made to the Borrower, then the interest rate in clause (i) above shall be 
the Prime Rate (adjusted daily) from and after such 2nd Business Day after 
the Advance was made until and including the date such Bank makes available 
to the Agent such Bank's portion of the Advance; PROVIDED, FURTHER, that if 
such Bank has not paid to the Agent such Bank's portion of the Advance by 
12:00 noon (Central Time) on the fifteenth (15th) Business Day after the 
Advance was made to Borrower, then the interest rate in clause (i) above 
shall be the Prime Rate (adjusted daily) plus three (3.0%) percent per annum 
from and after such 15th Business Day after the Advance was made until and 
including the date such Bank makes available to the Agent such Bank's portion 
of the Advance. A statement of the Agent submitted to each Bank with respect 
to any amounts owing under this paragraph shall be PRIMA 

<PAGE>

                                       18

FACIE evidence of the amount due and owing to the Agent by such Bank. If any 
Bank fails to pay to Agent its portion of any Advance within thirty (30) days 
after an Advance or if any Bank twice fails to timely make its portion of 
Advances to be made to the Borrower available to the Agent before 12:00 noon 
(Central Time) on the dates Advances are made to the Borrower (counting 
failures in reimbursement under Subsection 2.1(c) as a failure hereunder), 
then, if requested to do so by the Borrower or any other Bank or the Agent, 
such Bank shall sell all of its interests, rights and obligations under this 
Agreement (including all of its Commitment and its portion of the Loan at the 
time owing to it) and the Note held by it to another Bank or bank under 
Section 9.6 hereof.

     Not later than 3:00 p.m. (Central Time) on the date property and timely 
requested for the Advance and upon fulfillment of the applicable conditions 
set forth in Article 7 of this Agreement, the Agent will make such Advance 
available to the Borrower in same day funds in the checking account 
maintained by the Borrower with the Agent and the credit advice resulting 
therefrom shall be mailed by the Agent to the Borrower.

     (g)  MINIMUM. Notwithstanding anything in this Agreement to the 
contrary, the aggregate principal amount of all LIBO Rate Advances having the 
same interest period shall be at least equal to $100,000.00; and if any LIBO 
Rate tranche would otherwise be in a lesser principal amount for any period, 
such tranche shall bear interest at the Prime Rate during such period.

     Section 2.2 BUSINESS DAYS. If the date for any payment, prepayment or 
fee payment hereunder falls on a day which is not a Business Day, then for 
all purposes of this Agreement (unless otherwise provided herein) the same 
shall be deemed to have fallen on the next following Business Day, and such 
extension of time shall in such case be included in the computation of 
payments of interest.

     Section 2.3 PAYMENTS. The Borrower shall make each payment hereunder and 
under the Notes and any Collateral Documents in lawful money of the United 
States of America in same day funds to the Agent at its main office in New 
Orleans, Louisiana not later than 11:00 a.m. (Central Time) on the day when 
due, or such other place in the United States as designated in writing by the 
Agent. The Agent shall promptly send to each Bank by federal wire transfer 
its respective proportionate share of all amounts to which the Banks are 
entitled. The Borrower hereby authorizes the Agent to charge from time to 
time against the Borrower's accounts with the Agent any amount so due. At the 
time of making each payment hereunder or under the Note, the Borrower shall 
specify to the Agent the Advances or other amounts payable by the Borrower 
hereunder to which such payment is to be applied. In the event the 

<PAGE>

                                       19

Borrower fails to so specify, or if an Event of Default has occurred and is 
continuing, the Agent may apply such payment as it my elect in its sole 
discretion (but in accordance with Section 2.9).

     Section 2.4 PREPAYMENT. (a) VOLUNTARY. The Borrower may prepay the Loan 
in full or in part at any time without payment of premium or penalty; 
provided, however, that (i) the Borrower shall give the Agent notice of each 
such prepayment of all or any portion of a LIBO Rate Advance no less than 
three (3) Business Days prior to prepayment, (ii) any LIBO Rate Advance may 
be prepaid only on the last day of the Interest Period for such LIBO Rate 
Advance, (iii) the Borrower shall give the Agent notice of each such 
prepayment of all or any portion of a Prime Rate Advance no less than one (1) 
Business Day prior to prepayment, (iv) the Borrower shall pay all accrued and 
unpaid interest on the amounts prepaid, and (v) no such prepayment shall 
serve to postpone the repayment when due of any other Indebtedness.

     (b)  MANDATORY. The Agent shall notify the Borrower of the result of 
each Borrowing Base redetermination by the Agent at least fifteen (15) days 
before such redetermined amount is to become effective. If at any time the 
outstanding principal balance of the Advances plus the aggregate undisbursed 
amount of all outstanding standby letters of credit under Subsection 2.1(c) 
shall exceed the Borrowing Base as established in the then effective 
Borrowing Base schedule, then within thirty (30) days after such excess 
occurs the Borrower shall (x) prepay the Advances (together with accrued 
interest on the amount to be prepaid to the date of payment) in an amount 
sufficient to reduce the Advances plus the aggregate undisbursed amount of 
all outstanding standby letters of credit to the Borrowing Base, and/or (y) 
execute, deliver and record such additional Collateral Documents pursuant to 
Section 3.1(iii) sufficient to induce the Agent to make an increased 
redetermination of the Borrowing Base to an amount not less than the 
outstanding principal balance of the Advances plus the aggregate undisbursed 
amount of all outstanding standby letters of credit.

     Section 2.5 FEES. (a) The Borrower shall pay to the Agent, for 
disbursement in accordance with Section 9.1(a) hereof to the Banks, an unused 
facility fee quarterly in arrears on the first day of each calendar quarter 
(each January 1, April 1, July 1 and October 1 and, if different, on the 
Maturity Date for the period after the end of the previous quarter), on the 
following basis: on the first day of each calendar quarter, beginning July 1, 
1998, the Borrower shall designate an amount for that quarter (the 
"Designated Availability"), not less than twenty-five million 
($25,000,000.00) dollars and up to the Commitment Limit. So long as the sum 
of the outstanding principal balance of the Advances plus the aggregate 
undisbursed amount of all standby letters of credit under Subsection 2.1(c) 
outstanding during such quarter at no time exceeds the Designated 
Availability for such quarter, then the Borrower shall pay to 

<PAGE>

                                       20

the Agent a commitment fee for that quarter in the amount equal to the sum of 
(x) one-half of one (0.50%) percent per annum on the average daily unused 
portion of the Designated Availability plus (y) one-eighth of one (0.125%) 
percent per annum on the difference between the average daily Commitment 
Limit and the Designated Availability. But if at any time during that quarter 
the sum of the principal balance of unpaid and outstanding Advances and the 
total undisbursed amount of all standby letters of credit outstanding as of 
such date of determination exceeds the Designated Availability, then the 
Borrower shall pay to the Agent a commitment fee for that quarter in the 
amount equal to one-half of one (0.50%) percent on the averaged daily unused 
portion of the Commitment Limit. For purposes hereof, the unused portion of 
the Commitment Limit shall be the Commitment Limit LESS the sum of the 
principal balance of unpaid and outstanding Advances and the total 
undisbursed amount of all standby letters of credit outstanding as of such 
date of determination, and the unused portion of the Designated Availability 
shall be the Designated Availability less the sum of the principal balance of 
unpaid and outstanding Advances and the total undisbursed amount of all 
standby letters of credit outstanding as of such date of determination. Such 
commitment fee shall be determined on the basis of a 360-day interest factor 
over the number of days in the actual calendar year (365 days or 366 days in 
a leap year). (The unused facility fee payable on July 1, 1998, shall be 
determined by using $20,000,000.00 as the amount of the Designated 
Availability, being the amount for the second calendar quarter of 1998 
designated by the Borrower under the Prior Credit Agreement, and by using 
$30,000,000.00 as the amount of the Commitment Limit, being the amount under 
the Prior Credit Agreement (designated therein as the "Commitment Amount") 
(see Section 2.2.9 thereof).)

     (b)  The Borrower shall pay to the Agent, for disbursement in accordance 
with Section 9.1(a) hereof to the Banks, on the Closing Date a nonrefundable 
loan origination fee equal to $50,000.00.

     (c)  The Borrower shall pay to the Agent, for its own account, such fees 
as are agreed to in a separate agreement between the Borrower and the Agent 
with respect to the Agent's services provided hereunder and in connection 
herewith.

     (d)  The Borrower agrees to reimburse the Agent quarterly in arrears on 
the last day of each quarter for the Agent's actual costs incurred during 
that quarter for the Agent's compliance with its environmental verification 
process in obtaining status reports or similar information from governmental 
agencies.

                                       21

     Section 2.6 USE OF PROCEEDS. The Borrower shall use the proceeds of the 
Loan solely for the acquisition and development of its oil and gas 
properties and other corporate needs including working capital and the 
issuance of letters of credit.

     Section 2.7 ADDITIONAL REGULATORY COSTS. If any governmental authority, 
central bank, or other comparable authority shall at any time impose, modify 
or deem applicable any reserve (including without limitation any imposed by 
the Board of Governors of the Federal Reserve System), special deposit or 
similar requirement against assets of, deposits with or for the account of, 
or credit extended by, the Agent or any Bank, or shall impose on the Agent or 
any Bank any other condition affecting an Advance or the obligation of the 
Agent or any Bank to make an Advance; and the result of any of the foregoing 
is to increase the cost to the Agent or such Bank of making or maintaining 
the Advances to the Borrower, or to reduce the amount of any sum received or 
receivable by the Agent or any Bank under this Agreement or under the Notes 
by an amount deemed by the Agent or any Bank to be material, then, within 
sixty (60) days after demand by the Agent or such Bank, the Borrower shall 
pay to the Agent or such Bank, for the account of the Agent or such Bank, 
such additional amount or amounts as will compensate the Agent or such Bank 
for such increased cost or reduction. The Agent or such Bank will promptly 
notify the Borrower of any event of which it has knowledge, occurring after 
the date hereof, which will entitle the Agent or such Bank to compensation 
pursuant to this Section. A certificate of the Agent or such Bank claiming 
mining compensation under this Section and setting forth the additional 
amount or amounts to be paid to it hereunder shall be conclusive in the 
absence of manifest error.

     Section 2.8 DEFAULT RATE. Anything in the Notes or in any other 
agreement, document or instrument to the contrary notwithstanding, effective 
upon an Event of Default or upon the Maturity Date, the Agent and the 
Required Banks shall have the right to prospectively increase the interest 
rate under the Notes to the Default Rate until the Notes are paid in full. 
Upon the acceleration of the principal amount of the Indebtedness represented 
by the Notes, the Accelerated principal balance of the Loan shall bear 
interest from the date of acceleration up to the date of actual payments (as 
well after as before Judgment) at the Default Rate. All such interest at the 
Default Rate shall be payable upon demand.

     Section 2.9 APPLICATION OF PAYMENTS. Payments made under this Agreement, 
the Notes or the Collateral Documents, whether made when due or after 
foreclosure on Collateral, for application to the Indebtedness Shall be 
applied to the Indebtedness as follows:

     (i)   To the Agent, with respect to fees and expenses accrued and 
outstanding (including without limitation reasonable attorneys' fees and 
expenses); 

<PAGE>

                                       22

     (ii)  To the Banks, ratably according to their Commitments, with respect 
to fees, expenses and late charges accrued and outstanding;

     (iii) To the Banks, ratably according to their Commitments, with respect 
to interest accrued and outstanding; and

     (iv)  To the Banks, ratably according to their Commitments, with respect 
to principal amounts of the Loan due and payable.

Payment made pursuant to realization under the Collateral Documents are also 
subject to the Intercreditor Agreement.

     Section 2.10 SHARING OF PAYMENTS. If any Bank, whether by setoff or 
otherwise, has payment made to it upon its portion of the Loan, other than 
pursuant to Section 2.7 or ADDENDUM 1, in a greater proportion than that 
received by any other Bank, such Bank agrees, promptly upon demand, to 
purchase a portion of the Loan held by the other Banks so that after such 
purchase each Bank will hold its ramble proportion of the Loan. If any Bank, 
whether in connection with setoff or amounts which might be subject to setoff 
or otherwise, receives collateral or other protection for its Indebtedness or 
such amounts which may be subject to setoff, such Bank agrees, promptly upon 
demand, to take such action necessary such that all Banks share in the 
benefits of such Collateral ratable in proportion to their Commitment. In 
case any such payment is disturbed by legal process, or otherwise, 
appropriate further adjustment shall be made. However, nothing in this 
Section 2.10 is intended, or shall be construed, to amend the provisions of 
or alter the application of the Intercreditor Agreement.

for the ratable benefit of the Banks.

     (ii)  UCC-1 Financing Statements executed by the Borrower filed in the 
State of Colorado.

covered by Title Opinions in favor of Agent may be added to the Collateral

value-to-loan value basis, and (y) require environmental reports.

     (iv)  Additional properties of the Borrower required to be added to the

the Indebtedness to the Agent and to each of the Banks, as well other Debt of 
the Borrower to the Initial Bank. The Banks confirm the application of the 
Intercreditor Agreement to govern such other Debt (including without 
limitation the Borrower's guaranty agreements in favor of the Initial Bank 
covering the indebtedness of Maverick and Primero), the Indebtedness and the 
Collateral Documents.

     Section 3.2 CONFIRMATION. The Borrower hereby reaffirms its original 
intention as stated in the Collateral Documents that said Collateral 
Documents secure the Indebtedness as extended and renewed from time to time, 
including without limitation this Agreement and the Notes executed by the 
Borrower pursuant to this Agreement. The Borrower confirms and agrees that 
said Collateral Documents securing the Indebtedness, this Agreement and the 
Notes include without limitation the documents described in Section 3.1 (i) 
and (ii) above. The Borrower hereby ratifies and confirms in all respects the 
Collateral Documents, which remain in full force and effect in accordance 
with all of their terms, conditions and provisions in favor of the Agent, for 
the ratable benefit of the Banks.

     Section 3.3 ACQUISITION COLLATERAL. After each acquisition by the 
Borrower of any interest in oil, gas and other mineral properties involving 
an expenditure (in money or property) exceeding five million ($5,000,000.00) 
dollars (whether in one transaction or a series of related transactions), the 
Borrower at its expense will promptly, and in no event later than sixty (60) 
days after such acquisition, complete the execution and recordation of 

<PAGE>

                                       24

appropriate Collateral Documents in favor of the Agent, for the ratable 
benefit of the Banks, and the submission of Title Opinions in favor of the 
Agent reasonably acceptable to the Agent, covering all such acquired 
properties. Without limiting the foregoing, the Borrower, the Agent and the 
Banks further agree that if the Borrower completes the acquisition of its

the Banks, on such properties or interests as provided in the preceding 
sentence, and (ii) the Agent and the Banks shall then make a mandatory 
re-determination of the Borrowing Base. As Of the Closing Date, the Agent and 
the Banks do not intend that the working interest in the Raton Basin 
properties of Infinity, if acquired by Borrower, will be subject to this 
Section 3.3.

consent of the Required Banks; and (iv) shall inform all the Banks of the 
taking of action or assertion of rights pursuant to this Section. Each Bank 
agrees with the Agent and the other Banks that the decisions and 
determinations of the Required Banks in enforcing this Agreement, the Notes 
and the Collateral Documents and guiding the Agent in those matters shall be 
binding upon all the Banks, including without limitation authorizing the 
Agent at the pro rata expense of all the Banks (to the extent not reimbursed 
by the Borrower) to retain attorneys to seek judgment on this Agreement, the 
Notes and the Collateral Documents. Each Bank agrees with the other Banks 
that it will not, without the consent of all the other Banks, separately seek 
to institute any legal action with respect to the Loan. The Agent shall in 
all cases be fully protected in acting, or in refraining from acting, 
hereunder and under any Collateral Document or the Intercreditor Agreement in 
accordance with written instructions signed by the Required Banks (or, where 
required, all the Banks), and such instructions and any action taken or 
failure to act pursuant thereto shall be binding on all of the Banks and on 
all of the holders of Notes, provided however that the Agent shall not be 
required to take any action which exposes the Agent to personal liability or 
which is contrary to this Agreement or the Intercreditor Agreement or 
applicable law.

     Section 9.4 BANK CREDIT DECISION. Each Bank acknowledges that it has, 
independently and without reliance upon the Agent or any other Bank and based 
on the financial statements referred to herein and such other documents and 
information as it has deemed appropriate, made its own credit analysis and 
decision to enter into this Agreement.

AS it shall deem appropriate at the time, continue to make its own credit 
decisions in taking or not taking action under this Agreement, the Notes and 
the Collateral Documents.

     Section 9.5 AGENT. The Agent shall have the same rights and powers under 
this Agreement, the Notes and the Collateral Documents as any other Bank and 
may exercise the same as though it were not the Agent; and the term "Bank" or 
"Banks" shall, unless otherwise expressly indicated, include Agent in its 
individual capacity. The Agent may accept deposits from, lend money to, act 
as trustee under indentures of, and generally engage in any kind of business 
with Borrower and its Subsidiaries as if the Agent were not the Agent and 
without any duty to account therefor to the Banks. The Banks acknowledge that 
the Intercreditor Agreement shall govern the relationship between the Initial 
Bank, the Agent and the Banks with respect to loans made by the Initial Bank 
to Primero, Maverick and other Persons secured at least in part by a guaranty 
by the Borrower secured by the Collateral.

pages to the Intercreditor Agreement containing the signature of the 
assignee, and (following the Effective Date, as defined in the applicable 
Assignment and Acceptance) payment by the assignee to the Agent for its own 
account of an assignment administration fee in the amount of $3,500.00, (vi) 
either the assignor or assignee shall have paid the Agent's reasonable costs 
and expenses (including without limitation attorneys' fees and expenses) in 
connection with the assignment, (vii) the Agent shall have delivered to the 
Borrower a fully executed copy of such Assignment and Acceptance, and (viii)

such Bank's status for purposes of determining exemption from United States 
withholding taxes with respect to all payments to be made to such Bank 
hereunder, and provided further that such foreign bank shall not transfer its 
interests, rights and obligations under this Agreement to any affiliate of 
such foreign bank unless such affiliate provides the Agent and the Borrower 
with the aforesaid tax forms. Upon satisfaction of each of the foregoing 
conditions and upon acceptance and notation by the Agent, from and after the 
Effective Date specified in each Assignment and Acceptance, which Effective 
Date shall be at least five (5) Business Days after the execution thereof, 
(x) the assignee thereunder shall be a party hereto and, to the extent 
provided in such Assignment and Acceptance, have the rights and obligations 
of a Bank, and (y) the assigning Bank shall, to the extent provided in such 
assignment, be released from its obligations under this Agreement. 
Notwithstanding the foregoing, the restrictions contained above in this 
Subsection 9.6(a) shall not apply to assignments to any Federal Reserve Bank, 
and the conditions set forth in clauses (i) and (ii) above shall not apply to 
assignments by any Bank to any Person which controls, is controlled by, or is 
under common control with, or is otherwise substantially affiliated with that 
Bank.

     (b)  Upon its receipt of an Assignment and Acceptance executed by the 
parties to such assignment together with any Note subject to such assignment 
and the written consent of the Agent and the Borrower to such assignment, the 
Agent shall give prompt notice thereof to the Borrower and the Banks. Within 
five (5) Business Days after receipt of such notice, the Borrower at its own 
expense, shall execute and deliver to the Agent, in exchange for the 
surrendered Note, a new Note to the order of such assignee(s) in an amount 
equal to the mount assumed by such assignee(s) pursuant to such Assignment 
and Acceptance and, if the assigning Bank has retained some portion of its 
obligations hereunder, a new Note to the order of the assigning Bank in an 
amount equal to the amount retained by it hereunder. Such new Note or Notes 
shall be in an aggregate principal amount equal to the aggregate principal 
amount of the surrendered Note, shall be dated the effective date of such 
Assignment and Acceptance and shall otherwise be in the form of the assigned 
Note. The surrendered Note shall be canceled and returned to the Borrower.

with the prior written consent of the Borrower (which consent will not be 
unreasonably withheld), may sell participations to one or more banks or other 
financial institutions (and such bank or banks or financial institution or 
financial institutions shall be bound by the terms of this Agreement, 
including without limitation this Section 9-6) in all or a portion of the 
Loan (including its Commitment) under this Agreement; PROVIDED that the 
selling Bank shall retain

                                       59

the sole right and responsibility to enforce the obligations of the Borrower 
relating to the Loan and that the only rights granted to the participant 
pursuant to such participation arrangements with respect to waivers, 
amendments or modifications of this Agreement shall be the right to approve 
waivers, amendments, or modifications  which require the consent of all of 
the Banks as provided in Section 10.4 hereof.

     Section 9.7 INDEMNIFICATION OF THE AGENT. The Banks ratably (computed by 
reference to each Bank's respective Commitment) shall indemnify the Agent, 
its respective affiliates and the respective shareholders, directors, 
officers, employees, agents and counsel of the foregoing (each an "AGENT 
INDEMNITEES") and hold each Agent Indemnitee harmless from and against any 
and all claims (whether groundless or otherwise), liabilities, losses, 
damages, costs and expenses of any kind (including, without limitation, (i) 
the reasonable fees and disbursements of counsel and (ii) any expenses for 
which the Agent has not been reimbursed by the Borrower as required by this 
Agreement) which may be incurred by such Agent Indemnitee arising out of or 
related to this Agreement or the transactions contemplated hereby, or the 
Agent's actions taken hereunder; PROVIDED that no Agent Indemnitee shall have 
the right to be indemnified hereunder for such Agent, Indemnitee's own gross 
negligence or willful misconduct, as determined by a court of competent 
jurisdiction, or to the extent that such claim relates to the breach by such 
Agent Indemnitee of its obligations under this Agreement. The foregoing shall 
survive the termination of this Agreement.

                                  ADDENDUM I

                             LIBO RATE PROVISIONS

     1.   The Agent shall determine the interest rate applicable to LIBO Rate 
Advances, and its determination shall be conclusive in the absence of 
manifest error. The Agent shall endeavor to notify the Borrower prior to the 
date on which an interest payment is due, provided that the failure of the 
Agent to provide such notice shall not affect the Borrower's obligation to 
pay interest on such date.  

     2.   If any applicable law or regulation, or the action of any 
applicable regulatory requirement increases the reserves or capital required 
to be maintained by any Bank or the Agent with respect to the Loan (including 
unfunded commitments and obligations on letter of credit), such Bank or the 
Agent shall promptly deliver a certificate to the Borrower specifying the 
additional amount as will compensate such Bank or the Agent for the 
additional costs, which certificate shall be conclusive in the absence of 
manifest error. The Borrower shall pay the amount specified in such 
certificate promptly upon receipt.  

     3.   If the Agent gives notice to the Borrower that no LIBO bid rate is 
quoted to the Agent (or otherwise that adequate and reasonable methods do not 
exist for ascertaining the LIBO Rate) for the applicable Interest Period or 
in the applicable amounts (which notice shall be conclusive and binding on 
the Borrower and the Banks absent manifest error), then (A) the obligation of 
the Agent and the Banks to make a LIBO Rate Advance and the ability of the 
Borrower to select the LIBO Rate for an Advance shall be suspended, and (B) 
the Borrower shall either prepay all LIBO Rate Advances for which an interest 
rate is to be determined on such date or the Loan shall thereafter bear 
interest at the Prime Rate.  

     4.   If any applicable domestic or foreign law, treaty, rule or 
regulation (whether now in effect or hereinafter enacted or promulgated, 
including Regulation D of the Board of Governors of the Federal Reserve 
System) or any interpretation or administration thereof by any governmental 
authority charged with the interpretation or administration thereof (whether 
or not having the force of law):  

          (i)   changes the basis of taxation of payments to any Bank or the
     Agent or any principal, interest, or other amounts attributable to any LIBO
     Rate Advance (other than taxes imposed on the overall net income of such
     Bank or the Agent);  

          (ii)  changes, imposes, modifies, applies or deems applicable any
     reserve, special deposit or similar requirements in respect of any such
     LIBO Rate Advance (excluding those for which such Bank or the Agent is
     fully compensated pursuant to

<PAGE>

                                                                     ADDENDUM I
                                                                     PAGE - 2 -

     adjustments made in the definition of LIBO Rate) or against assets of,
     deposits with or for the account of, or credit extended by, any Bank or the
     Agent; or  

          (iii) imposes on any Bank or the Agent or the interbank euroccurrency
     deposit  and transfer market any other condition or requirement affecting
     any such LIBO Rate Advance,

and the result of any of the foregoing is to increase the cost to such Bank 
or the Agent of  funding or maintaining any such LIBO Rate Advance (other 
than costs for which such Bank or  the Agent is fully compensated pursuant to 
adjustments made in the definition of LIBO Rate)  or to reduce the amount of 
any sum receivable by such Bank or the Agent in respect of any  such LIBO 
Rate advance by an amount deemed by such Bank or the Agent to be material, 
then  such Bank or the Agent shall promptly notify the Borrower in writing of 
the happening of such  event and (1) Borrower shall upon demand pay to such 
Bank or the Agent such additional  amount or amounts as will compensate such 
Bank or the Agent for such additional cost or  reduction and (2) Borrower may 
elect, by giving to the Agent not less than three Business  Days' notice, to 
change the interest rate applicable to such Advance, and any other portion of 
the Loan bearing interest at the LIBO Rate, to the Prime Rate.  

     5.   Notwithstanding any other provision hereof, if any change in 
applicable laws, treaties, rules or regulations or in the interpretation or 
administration thereof of or in any jurisdiction whatsoever, domestic or 
foreign, shall make it unlawful or impracticable for any Bank to maintain 
Advances bearing interest at the LIBO Rate, or shall materially restrict the 
authority of any Bank to purchase, sell or take certificates of deposit or 
offshore deposits of dollars, then, upon notice by such Bank to Borrower and 
the Agent, such Bank's portion of all LIBO Rate Advances which are then 
outstanding and which cannot lawfully or practicably be maintained shall 
immediately cease to bear interest at the LIBO Rate and shall commence to 
bear interest at the Prime Rate. The Borrower agrees to indemnify each Bank 
and hold it harmless against all costs, expenses, claims, penalties, 
liabilities and damages which may result from any such change in law, treaty, 
rule, regulation, interpretation or administration. The Borrower hereby 
agrees promptly to pay the Agent for the account of such Bank, upon demand by 
such Bank, any additional amounts necessary to compensate such Bank for any 
costs incurred by such Bank in making any conversation in accordance with 
this Paragraph, including any interest or fees payable by such Bank to 
lenders of funds obtained by it in order to make or maintain hereunder its 
portion of the Loan accruing interest based on the LIBO Rate.  

     6.   The Borrower will indemnify the Agent and each Bank against, and 
reimburse the Agent and each Bank on demand for, any loss or expense incurred 
or sustained by the Agent and each Bank (including without limitation, any 
loss or expense incurred by reason of

<PAGE>

                                                                     ADDENDUM I
                                                                     PAGE - 3 -

the liquidation or reemployment of deposits or other funds acquired by the 
Agent and each Bank to fund or maintain LIBO Rate Advances) as a result of 
(i) any payment or prepayment (whether authorized or required hereunder or 
otherwise) of all or a portion of any LIBO Rate  Advance on a day other than 
the day on which the applicable Interest Period ends, (ii) any  payment or 
prepayment, whether required hereunder or otherwise, of the LIBO Rate 
Advances  made after the delivery, but before the effective date, of an 
election to have the LIBO Rate apply to LIBO Rate Advance, if such payment or 
prepayment prevents such election from  becoming fully effective or (iii) the 
failure of any LIBO Rate Advance to be made by the  Agent and each Bank or of 
any such election to become effective due to any condition  precedent to a 
LIBO Rate Advance not being satisfied or due to any other action or inaction 
of  Borrower. For purposes of this section, funding losses arising by reason 
of liquidation or  reemployment of deposits or other funds acquired by the 
Agent or any Bank to fund or  maintain LIBO Rate Advances shall be calculated 
as the remainder obtained by subtracting:  (1) the yield (reflecting both 
stated interest rate and discount, if any) to maturity of obligations  of the 
United States Treasury as determined by the Agent or such Bank in an amount 
equal or  comparable to such advance for the period of time commencing on the 
date of the payment,  prepayment or change of rate as provided above and 
ending on the last day of the subject  Interest Period, from (2) the LIBO 
Rate of the subject Interest Period, TIMES the number of  days from the date 
of payment, prepayment or change of rate to the last day of the subject 
Interest Period, divided by 360. Any payment due under this paragraph will be 
paid to the  Agent or such Bank within five days after demand therefor by the 
Agent or such Bank.  

     7.   The Borrower covenants and agrees that:

          (i)   The Borrower will pay, within five days after notice thereof
     from Agent (on behalf of itself or any Bank) and on an after-tax basis, all
     present and future income, stamp and other taxes, levies, costs and charges
     whatsoever imposed, assessed, levied or collected on or in respect of any
     LIBO Rate Advance whether or not legally or correctly imposed, assessed,
     levied or collected (excluding taxes, levies, costs or charges imposed on
     or measured by the overall net income of the Agent or any Bank) (all such
     non-excluded taxes, levies, costs and charges being collectively called
     "REIMBURSABLE TAXES"). Promptly after the date on which payment of any
     Reimbursable Taxes is due pursuant to applicable law, the Borrower will, at
     the request of the Agent, furnish to the Agent evidence in form and
     substance satisfactory to the Agent that Borrower has met its obligation
     under this paragraph.

          (ii)  The Borrower will indemnify the Agent and each Bank against,
     and reimburse the Agent and each Bank on demand for, any Reimbursable Taxes
     paid by the Agent or such Bank and any loss, liability, claim or expense,
     including interest, penalties and legal fees, that the Agent and each Bank
     may incur at any time arising out

                                                                     ADDENDUM 1
                                                                     PAGE - 4 -

     of or in connection with the failure of Borrower to make any payment of
     Reimbursable Taxes when due, unless such failure is due to Agent or such
     Bank's failure to give notice to Borrower of Borrower's obligation to pay
     such Reimbursable Taxes at least five days prior to the date when they are
     due. Any payment due under this subsection will be paid to the Agent or
     such Bank within five days after demand therefor by the Agent or such Bank.

          (iii)  All payments on account of the principal of, and interest on,
     LIBO Rate Advances and all other amounts payable by Borrower to the Agent
     and the Banks hereunder shall be made free and clear of and without
     reduction by reason of any Reimbursable Taxes.

          (iv)   If Borrower is ever required to pay any Reimbursable Taxes
     with respect to any LIBO Rate Advance, Borrower may elect, by giving to the
     Agent not less than three (3) Business Days' notice, to change the interest
     rate applicable to any such advance from the LIBO Rate to the Prime Rate,
     but such election shall not diminish Borrower's obligation to pay all
     Reimbursable Taxes therefore imposed, assessed, levied or collected.

Promise to Pay. EVERGREEN RESOURCES, INC., a Colorado corporation ("Borrower"),
promises to pay to the order of __________ ("Bank"), at the main office in New
Orleans (313 Carondelet Street) of Hibernia National Bank (the "Agent"), in
lawful money of the United States of America, the sum of fifty million and
00/100 dollars (U.S. $50,000,000.00) or such other or lesser amount as from time
to time equals the aggregate unpaid principal balance of loan advances made to
Borrower by Bank on a revolving line of credit basis as provided below, together
with simple interest assessed on the variable rate(s) basis provided below, with
interest being assessed on the unpaid principal balance of this Note as
outstanding from time to time, computed as set forth in the Credit Agreement (as
defined below).

Credit Agreement. This note is a Note referred to in that certain Amended and
Restated Credit Agreement dated as of July 1, 1998, among Borrower, Agent and
the banks from time to time party thereto (as amended, renewed or restated from
time to time, the "Credit Agreement"). Unless otherwise defined herein, each
capitalized term used herein shall have the same meaning set forth in the Credit
Agreement. Reference is made to the Credit Agreement for provisions for the
acceleration of the maturity hereof on the occurrence of certain events
specified therein, for mandatory prepayments required of the Borrower in certain
circumstances, and for all other pertinent provisions.

Line of Credit. This Note evidences revolving line of credit advances that may
be made from time to time to Borrower under the Credit Agreement (including loan
advances arising from draws on standby letters of credit issued thereunder at
the request of the Borrower). The unpaid principal balance owing on this Note at
any time may be evidenced by endorsements on this Note or by Agent's or Bank's
internal records, including daily computer print-outs. Advances shall only be
made in accordance with the terms and conditions of the Credit


<PAGE>

                                                                      EXHIBIT A
                                                                     PAGE - 2 -

Agreement. The credit advice resulting from the deposit of the proceeds of any
disbursement hereunder in the Borrower's account with the Agent, or the Agent's
copy of any cashier's check representing all or any part of the proceeds of the
disbursements, shall be deemed prima facie evidence of the Borrower's
indebtedness to the Bank on the Loan.

Payments. Borrower will pay interest on Prime Rate Advances at the Prime Rate
monthly in arrears on the last day of each successive calendar month. Borrower
will pay interest on LIBO Rate Advances at the applicable LIBO Rate in arrears
on the last day of each LIBO Rate Interest Period applicable to each LIBO Rate
Advance. Borrower will pay the balance of all outstanding principal on this
Note, together with all accrued but unpaid interest, on July 1, 2001. Interest
on this Note is computed on a 365/360 simple interest basis; that is, by
applying the ratio of the annual interest rate over a year of 360 days, times
the outstanding principal balance, times the actual number of days the principal
balance is outstanding. Borrower will pay Bank at Agent's address shown above or
at such other place as Bank may designate in writing. All payments and
prepayments made by the Borrower hereunder shall be made to the Agent, in
immediately available funds, before 11:00 a.m. (Central Time) on the day that
such payment is required, or otherwise is, to be made. Any payment received and
accepted by the Agent after such time shall be considered for all purposes
(including the calculation of interest, to the extent permitted by law) as
having been made on the next following Business Day. Whenever any payment to be
made hereunder falls on a day other than a Business Day, then unless otherwise
provided in the Credit Agreement such payment shall be made on the next 
succeeding Business Day, and such extension of time shall in each case 
be included in the calculation of interest.

Variable Interest Rate(s). This Note bears interest on and after the date 
hereof to and including the Maturity Date at the variable rate(s) per annum 
equal to the Prime Rate or LIBO Rate, as selected by Borrower in accordance 
with the Credit Agreement. The interest rate on this Note is subject to 
change from time to time based on changes in the Prime Rate and the LIBO 
Rate. If the index rate used in determining the Prime Rate becomes 
unavailable during the term of this Note, Agent may designate a substitute 
index after notice to Borrower. Agent will tell Borrower the Prime Rate upon 
Borrower's request. Borrower understands that Bank may make loans based on 
other rates as well. The interest rate change will not occur more often than 
each day. The unpaid principal balance of this Note shall bear interest from 
and after an Event of Default or the Maturity Date until paid at the Default 
Rate from time to time in effect.

Prepayment. Borrower may prepay this Note in full by paying the then unpaid
principal balance of this Note, plus accrued simple interest through date of
prepayment, subject to restrictions regarding permitted timing (with respect to
LIBO Rate Advances) and advance

                                                                      EXHIBIT A
                                                                     PAGE - 3 -

notice set forth in the Credit Agreement. Borrower may be required to prepay
this Note from time to time in accordance with the Credit Agreement.

Event of Default. If any Event of Default occurs, Agent and Bank shall have all
of the rights and remedies (including acceleration of the Maturity Date of this
Note) available to them pursuant to the Credit Agreement or applicable law.

Attorneys' Fees. If Bank refers this Note to an attorney for collection, or
files suit against Borrower to collect this Note, or if Borrower files for
bankruptcy or other relief from creditors, Borrower agrees to pay the Agent's
and the Bank's reasonable attorneys' fees.

Deposit Accounts. As collateral for repayment of this Note and all renewals and
extensions, as well as to secure any and all other Indebtedness that Borrower
may now and in the future owe to Agent or any Bank in connection with the Credit
Agreement, Borrower hereby grants Agent for itself and the ratable benefit of
the Banks a continuing security interest in any and all funds that Borrower may
now and in the future have on deposit with Agent or in certificates of deposit
or other deposit accounts as to which Borrower is an account holder (with the
exception of any funds held in any of Borrower's accounts in trust for third
parties, or funds held in IRA, pension, and other tax-deferred deposits).

GOVERNING LAW. BORROWER AGREES THAT THIS NOTE AND THE LOAN EVIDENCED HEREBY
SHALL BE GOVERNED UNDER THE LAWS OF THE STATE OF LOUISIANA. SPECIFICALLY, THIS
BUSINESS OR COMMERCIAL NOTE IS SUBJECT TO LA. R.S. 9:3509 ET SEQ.

Collateral. This Note is secured by the Collateral Documents described in the
Credit Agreement.

Waivers. Borrower waives presentment for payment, protest, notice of protest and
notice of nonpayment, diligence in taking any action to collect amounts called
for hereunder and in the handling of property at any time existing as security
in connection herewith, and shall be directly and primarily liable for the
payment of all sums owing and to be owing hereon, regardless of and without any
notice, diligence, act or omission as or with respect to the collection of any
amount called for hereunder or in connection with any right, lien, interest or
property at any and all times had or existing as security for any amount called
for hereunder.

Usury Considerations. It is the intention of Borrower to conform strictly to
applicable usury laws. Accordingly, if the transactions contemplated hereby
would be usurious under applicable law (excluding applicable Louisiana law),
then, in that event notwithstanding anything to the contrary in any agreement
entered into as security for this Note, it is agreed as

                                                                      EXHIBIT A
                                                                     PAGE - 4 -

follows: (i) the aggregate of all interest that is taken, reserved, contracted
for, charged or received under this Note or under any of the other aforesaid
agreements or otherwise in connection with this Note shall under no
circumstances exceed the maximum amount of interest allowed by applicable law,
and any excess shall be credited on this Note by the holder hereof (or if the
Note shall have been paid in full, refunded to Borrower); and (ii) in the event
that maturity of this Note is accelerated by reason of default hereunder or
otherwise, or in the event of any permitted prepayment, then such consideration
that constitutes interest may never include more than the maximum amount allowed
by applicable law, and excess interest, if any, provided for in this Note or
otherwise shall be cancelled automatically as of the date of such acceleration 
or prepayment and, if theretofore prepaid, shall be credited on this Note (or 
if this Note shall have been paid in full, refunded to Borrower). To the 
extent that Louisiana law would be deemed the applicable law (as is the 
intent of Borrower hereunder), the provisions of the Section 2.8 in the 
Credit Agreement entitled Default Rate shall control.

Submission to Jurisdiction; Waiver of Jury Trial.

     (a) Borrower hereby irrevocably and unconditionally:

          (1)    submits for itself and its property in any legal action or
                 proceedings relating to this Note, or for recognition and
                 enforcement of any judgment in respect thereof, to the
                 non-exclusive general jurisdiction of the courts of the State
                 of Louisiana, the courts of the United States of America for
                 the Eastern District of Louisiana, and appellate courts from
                 any thereof;

          (2)    consents that any such action or proceedings may be brought in
                 such courts, and waives any objections that it may now or
                 hereafter have to the venue of any such action or proceeding

                                                                     PAGE - 2 -

by the Borrower in favor of the Subordinated Creditor, securing the obligations,
liabilities and indebtedness of other Persons to the Subordinated Creditor,
including without limitation the Borrower's Guaranty Agreement dated effective
January 24, 1997, for debt owed by Maverick Stimulation Company, LLC, a Colorado
limited liability company, and the Borrower's Guaranty Agreement dated as of
June 1, 1998, for loan debt owed by Primero Gas Marketing Company, a Colorado

the Collateral pursuant to the Mortgage.

Agent and the Banks to the Borrower pursuant to the Credit Agreement, the Agent

interest in the Collateral as security for the Subordinated Debt to the Agent's
interest in the Collateral as security for the Senior Indebtedness, and
Subordinated Creditor is willing to do so.

                                                                      EXHIBIT C
                                                                      PAGE - 3 -

     NOW, THEREFORE, for and in consideration of the premises, the Subordinated
Creditor and the Borrower hereby agree as follows:

     Section 1.  SUBORDINATION REGARDING COLLATERAL. The Subordinated Creditor
hereby agrees that upon the foreclosure, sale, set-off or other realization
against any of the Collateral, the Senior Indebtedness shall be paid by
preference and priority over the Subordinated Debt from and as to the proceeds
of the Collateral. The foregoing subordination pertains solely to realization
against the Collateral and the proceeds therefrom. and is not a general
subordination of the Subordinated Debt to the Senior Indebtedness for other
purposes. The Subordinated Creditor shall have the right to receive, and the
Borrower shall have the right and obligation to pay, all amounts owing as part
of the Subordinated Debt to be paid by the Borrower to the Subordinated Creditor
as and when due. The foregoing subordination pertains only to the proceeds
arising from the foreclosure, sale, set-off or other realization on any of the
Collateral by the Agent, the Banks and the Subordinated Creditor pursuant to the
remedies provided by the Mortgage.

     Section 2.  LIQUIDATION PAYMENTS. (a) The Subordinated Creditor and the
Borrower agree that, in the event of any distribution, division or 
application, partial or complete, voluntary or involuntary, by operation of 
law or otherwise, of all or any part of the Collateral to creditors of 
Borrower, or in the event of any liquidation, dissolution or other winding up 
of Borrower or Borrower's business, or in the event of any sale, 
receivership, insolvency or bankruptcy proceeding, assignment for the benefit 
of creditors, or proceeding by or against Borrower for any relief under any 
bankruptcy or insolvency law or laws relating to the relief of debtors, 
readjustment of indebtedness, reorganizations, compositions or extensions. 
then and in any such event any payment or distribution of any kind or 
character, either in cash or other property, which shall be payable or 
deliverable upon or with respect to any or all of the Collateral shall be 
paid or delivered directly to the Agent for application on any Senior 
Indebtedness until the Senior Indebtedness shall have been fully paid and 
satisfied.

     (b)  The Agent shall have the right to enforce, collect and receive any
payments described in Subsection (a) hereof and to grant full acquittance
therefor, and the Agent is hereby authorized (as attorney-in-fact for the
Subordinated Creditor pursuant to an irrevocable power of attorney coupled with
an interest) to file claims, vote, and prove the Subordinated Debt in any
proceedings or meetings of creditors described in Subsection (a) hereof, but
insofar only as the Subordinated Debt or such proceedings or meetings directly
relate to the Collateral and distribution thereof.

     Section 3.  REMITTANCE OF PAYMENTS. Should any payment or distribution
from any such realization upon any of Collateral or proceeds thereof (except
payments permitted by Section 1 hereof) be received by Subordinated Creditor
upon or with respect to any


<PAGE>

                                                                      EXHIBIT C
                                                                      PAGE - 4 -

Subordinated Debt prior to the payment and satisfaction in full of all of the
Senior Indebtedness, Subordinated Creditor will forthwith deliver the same to
the Agent in precisely the form received (except for the endorsement, without
recourse, or assignment of Subordinated Creditor where necessary), for
application on the Senior Indebtedness, and, until so delivered, the same shall
be held in trust by Subordinated Creditor as property of the Agent. In the event
of the failure of Subordinated Creditor to make any such endorsement or
assignment, the Agent, or any of its officers or employees in behalf of the
Agent, is hereby irrevocably authorized to make the same.

     Section 4.  NOTICE OF ACTION. The Subordinated Creditor agrees to send the
Agent a copy of each notice that the Subordinated Creditor gives to the Borrower
pertaining to an alleged default or event of default under the Subordinated Debt
simultaneously with the giving of such notice to the Borrower. The Agent agrees
to give the Subordinated Creditor a copy of each notice that the Agent gives to
the Borrower under the Credit Agreement pertaining to a default or an event of
default thereunder simultaneously with the giving of such notice to the
Borrower. Notwithstanding the two foregoing sentences, neither party shall have
any greater rights to notice, if any, then the right of the Borrower under such
documents governing the Senior Indebtedness or the Subordinated Debt, as
applicable; provided, however, that the parties shall be obligated to provide
the notices set forth in Section 5 below.

     Section 5.  ACTIONS. (a) Until the earlier to occur of (i) the payment 
in full to the Agent and the Banks of the Senior Indebtedness, or (ii) a 
bankruptcy of the Borrower or other event which would cause an automatic 
acceleration of the Senior Indebtedness under the Credit Agreement, or (iii) 
any action being taken by the Agent against the Collateral under the Mortgage 
to enforce the rights of the Agent and the Banks under the Credit Agreement, 
the Subordinated Creditor agrees that it will not take any of the following 
actions without first having given the Agent fifteen (15) days' advance 
notice thereof:

          (1)    Seize, foreclose on or otherwise realize upon or sell any
Collateral encumbered by the Mortgage; or

          (2)    Notify any account debtor or other Person who is an obligor of
the Borrower with respect to accounts, general intangibles or other obligations
included within the Collateral encumbered by the Mortgage to make payments
directly to the Subordinated Creditor (or any agent or designee thereof); or

          (3)    Collect by legal proceedings or otherwise any payments,
proceeds or other sums and property now or hereafter payable on account of
Collateral encumbered by the Mortgage; or


<PAGE>

                                                                      EXHIBIT C
                                                                      PAGE - 5 -

          (4)    Make any compromise or settlement or enter into any extension
agreement with any Person who is an obligor of the Borrower with respect to
accounts, general intangibles or other obligations included within the
Collateral encumbered by the Mortgage.

     (b)  Until such time as the Subordinated Creditor has received payment in
full of all Subordinated Debt, the Agent agrees to give the Subordinated
Creditor written notice reasonably in advance of (but in no event later than
simultaneously with) the taking of any action (whether foreclosure, sale,
set-off or other realization of any type) against any of the Collateral.

     Section 6.  MODIFICATIONS OF SENIOR INDEBTEDNESS. The Subordinated
Creditor agrees that the Agent and the Banks, at any time and from time to time,
may enter into such agreement or agreements with Borrower as the Agent and the
Banks may deem proper, extending the time of payment or increasing or renewing
or otherwise altering the terms of all or any of the Senior Indebtedness
without notice to Subordinated Creditor and without in any way impairing or
affecting this Agreement. However, although the Agent may release any portion of
the Collateral insofar as it secures the Senior Indebtedness, the Agent does not
have the power to release the Subordinated Creditor's lien on the Collateral
under the Mortgage insofar as it secures the Subordinated Debt.

     Section 7.  DURATION. (a) The subordinations, agreements and priorities set

     (b)  The Agent and the Banks agree not to contest the validity, perfection,
priority or enforceability of any of the Subordinated Debt or the lien of the
Mortgage securing same or the validity or enforceability of this Agreement.

     Section 9.  SUBORDINATED DEBT. (a) The Subordinated Creditor acknowledges
the limitations established by Section 6.1 and Section 6.2 of the Credit
Agreement on the maximum amount of Subordinated Debt owed by Borrower permitted
thereby and permitted to be secured by the Collateral under the Mortgage.

     (b)  Subject to Subsection 9(a) above, the Agent and the Banks agree that
the Subordinated Creditor, at any time and from time to time, may enter into
such agreement or agreements with Borrower as the Subordinated Creditor may deem

Subordinated Debt without notice to the Agent and the Banks and without in any
way impairing or affecting this Agreement.

     Section 10. NO THIRD-PARTY BENEFICIARY. This Agreement and the terms and
provisions hereof are solely for the benefit of the Agent and the Banks, and the
Subordinated Creditor, and their respective successors and assigns, and shall
not benefit the Borrower or any other Person not specifically a party to this
Agreement now or in the future. Nothing contained in this Agreement is intended

Nothing in this Agreement is intended to affect, limit or in any way diminish
the security interest which the Agent and the Banks, and the Subordinated
Creditor, claim in the Collateral insofar as the rights of the Borrower and
third Persons are concerned. The parties hereto specifically reserve any and all
of their respective rights, security interests and liens against the Collateral
and right to assert the same against the Borrower and any third Persons. Without
limiting the generality of the foregoing, nothing contained in this Agreement
shall in any manner affect the direct obligations of the Borrower or any other
Person to the Subordinated Creditor pertaining to the Subordinated Debt. The
Borrower acknowledges and consents to all the terms of this Agreement but is not
a beneficiary hereof and does not have any rights hereunder.

PROMISE TO PAY. EVERGREEN RESOURCES, INC., a Colorado corporation ("Borrower"),
promises to pay to the order of HIBERNIA NATIONAL BANK ("Bank"), at the main
office in New Orleans (313 Carondelet Street) of Hibernia National Bank (the
"Agent"), in lawful money of the United States of America, the sum of
twenty-five million and 00/100 dollars (U.S. $25,000,000.00) or such other or
lesser amount as from time to time equals the aggregate unpaid principal balance
of loan advances made to Borrower by Bank on a revolving line of credit basis as
provided below, together with simple interest assessed on the variable rate(s)
basis provided below, with interest being assessed on the unpaid principal
balance of this Note as outstanding from time to time, computed as set forth in
the Credit Agreement (as defined below).

CREDIT AGREEMENT. This now is a Note referred to in that certain Amended and
Restated Credit Agreement dated as of July 1, 1998, among Borrower, Agent and
the banks from time to time party thereto (as amended, renewed or restated from
time to time, the "Credit Agreement"). Unless otherwise defined herein, each
capitalized term used herein shall have the same meaning set forth in the Credit
Agreement. Reference is made to the Credit Agreement for provisions for the
acceleration of the maturity hereof on the occurrence of certain events
specified therein, for mandatory prepayments required of the Borrower in certain
circumstances, and for all other pertinent provisions.

LINE OF CREDIT. This Note evidences revolving line of credit advances that may
be made from time to time to Borrower under the Credit Agreement (including loan
advances arising from draws on standby letters of credit issued thereunder at
the request of the Borrower). The unpaid principal balance owing on this Note at
any time may be evidenced by endorsements on this Note or by Agent's or Bank's
internal records, including daily computer print-outs. Advances shall only be
made in accordance with the terms and conditions of the Credit Agreement. The
credit advice resulting from the deposit of the proceeds of any disbursement
hereunder in the Borrower's account with the Agent, or the Agent's copy of 
any cashier's check representing all or any part of the proceeds of the 
disbursements, shall be deemed prima facie evidence of the Borrower's 
indebtedness to the Bank on the Loan.

                                       -2-


PAYMENTS. Borrower will pay interest on Prime Rate Advances at the Prime Rate
monthly in arrears on the last day of each successive calendar month. Borrower
will pay interest on LMO Rate Advances at the applicable LIBO Rate in arrears on
the last day of each LIBO Rate Interest Period applicable to each LIBO Rate
Advance. Borrower will pay the balance of all outstanding principal on this
Note, together with all accrued but unpaid interest, on July 1, 2001. Interest
on this Note is computed on a 365/360 simple interest basis; that is, by
applying the ratio of the annual interest rate over a year of 360 days, times
the outstanding principal balance, times the actual number of days the principal
balance is outstanding. Borrower will pay Bank at Agent's address shown above or
at such other place as Bank may designate in writing. All payments and 
prepayments made by the Borrower hereunder shall be made to the Agent, in 
immediately available funds, before 11:00 a.m. (Central Time) on the day that 
such payment is required, or otherwise is, to be made. Any payment received 
and accepted by the Agent after such time shall be considered for all 
purposes (including the calculation of interest, to the extent permitted by 
law) as having been made on the next following Business Day. Whenever any 
payment to be made hereunder falls on a day other than a Business Day, then 
unless otherwise provided in the Credit Agreement such payment shall be made 
on the next succeeding Business Day, and such extension of time shall in each 
case be included in the calculation of interest.

VARIABLE INTEREST RATE(S). This Note bears interest on and after the date hereof
to and including the Maturity Date at the variable rate(s) per annum equal to
the Prime Rate of LIBO Rate, as selected by Borrower in accordance with the
Credit Agreement. The interest rate on this Note is subject to change from time
to time based on changes in the Prime Rate and the LIBO Rate. If the index rate
used in determining the Prime Rate becomes unavailable during the term of this
Note, Agent may designate a substitute index after notice to Borrower. Agent
will tell Borrower the Prime Rate upon Borrower's request. Borrower understands
that Bank may make loans based on other rates as well. The interest rate change
will not occur more often than each day. The unpaid principal balance of this
Note shall bear interest from and after an Event of Default or the Maturity Date
until paid at the Default Rate from time to time in effect.

PREPAYMENT. Borrower may prepay this Note in full by paying the then unpaid
principal balance of this Note, plus accrued simple interest through date of
prepayment, subject to restrictions regarding permitted timing (with respect to
LIBO Rate Advances) and advance notice set forth in the Credit Agreement.
Borrower may be required to prepay this Note from time to time in accordance
with the Credit Agreement.

                                       -3-

EVENT OF DEFAULT. If any Event of Default occurs, Agent and Bank shall have all
of the rights and remedies (including acceleration of the Maturity Date of this
Note) available to them pursuant to the Credit Agreement or applicable law.

ATTORNEYS' FEES. If Bank refers this Note to an attorney for collection, or
files suit against Borrower to collect this Note, or if Borrower files for
bankruptcy or other relief from creditors, Borrower agrees to pay the Agent's
and the Bank's reasonable attorneys' fees.

DEPOSIT ACCOUNTS. As collateral for repayment of this Note and all renewals and
extensions, as well as to secure any and all other Indebtedness that Borrower
may now and in the future owe to Agent or any Bank in connection with the Credit
Agreement, Borrower hereby grants Agent for itself and the ratable benefit of
the Banks a continuing security interest in any and all funds that Borrower may
now and in the future have on deposit with Agent or in certificates of deposit
or other deposit accounts as to which Borrower is an account holder (with the
exception of any funds held in any of Borrower's accounts in trust for third
parties, or funds held in IRA, pension, and other tax-deferred deposits).

SHALL BE GOVERNED UNDER THE LAWS OF THE STATE OF LOUISIANA. SPECIFICALLY, THIS
BUSINESS OR COMMERCIAL NOTE IS SUBJECT TO LA. R.S. 9:3509 ET SEQ.

Credit Agreement.

WAIVERS. Borrower waives presentment for payment, protest, notice of protest and
notice of nonpayment, diligence in taking any action to collect amounts called
for hereunder and in the handling of property at any time existing as security
in connection herewith, and shall be directly and primarily liable for the
payment of all sums owing and to be owing hereon, regardless of and without any
notice, diligence. act or omission as or with respect to the collection of any
amount called for hereunder or in connection with any right, lien, interest or
property at any and all times had or existing as security for any amount called
for hereunder.

USURY CONSIDERATIONS. It is the intention of Borrower to conform strictly to
applicable usury laws. Accordingly, if the transactions contemplated hereby
would be usurious under applicable law (excluding applicable Louisiana law),
then, in that event notwithstanding anything to the contrary in any agreement
entered into as security for this Note, it is agreed as follows: (i) the
aggregate of all interest that is taken, reserved, contracted for, charged or

<PAGE>


                                      -4-

received under this Note or under any of the other aforesaid agreements or
otherwise in connection with this Note shall under no circumstances exceed the
maximum amount of interest allowed by applicable law, and any excess shall be
credited on this Note by the holder hereof (or if the Note shall have been paid
in full, refunded to Borrower); and (ii) in the event that maturity of this Note
is accelerated by reason of default hereunder or otherwise, or in the event of
any permitted prepayment, then such consideration that constitutes interest may
never include more than the maximum amount allowed by applicable law, and excess
interest, if any, provided for in this Note or otherwise shall be canceled
automatically as of the date of such acceleration or prepayment and, if
theretofore prepaid, shall be credited on this Note (or if this Note shall have
been paid in full, refunded to Borrower). To the extent that Louisiana law would
be deemed the applicable law (as is the intent of Borrower hereunder), the
provisions of the Section 2.8 in the Credit Agreement entitled DEFAULT RATE
shall control.

certain events specified therein, for mandatory prepayments required of the 
Borrower in certain circumstances, and for all other pertinent provisions.

LINE OF CREDIT. This Note evidences revolving line of credit advances that may
be made from time to time to Borrower under the Credit Agreement (including loan
advances arising from draws on standby letters of credit issued thereunder at
the request of the Borrower). The unpaid principal balance owing on this Note at
any time may be evidenced by endorsements on this Note or by Agent's or Bank's
internal records, including daily computer print-outs. Advances shall only be
made in accordance with the terms and conditions of the Credit Agreement. The
credit advice resulting from the deposit of the proceeds of any disbursement
hereunder in the Borrower's account with the Agent, or the Agent's copy of any
cashier's check representing all or any part of the proceeds of the
disbursements, shall be deemed prima facie evidence of the Borrower's
indebtedness to the Bank on the Loan.

PAYMENTS. Borrower will pay interest on Prime Rate Advances at the Prime Rate 
monthly in arrears on the last day of each successive calendar month. 
Borrower will pay interest on LIBO Rate Advances at the applicable LIBO Rate 
in arrears on the last day of each LIBO Rate Interest Period applicable to 
each LIBO Rate Advance. Borrower will pay the balance of all outstanding 
principal on this Note, together with all accrued but unpaid interest, on 
July 1, 2001. Interest on this Note is computed on a 365/360 simple interest 
basis; that is, by applying the ratio of the annual interest rate over a year 
of 360 days, times the outstanding principal balance, times the actual number 
of days the principal balance is outstanding. Borrower will pay Bank at 
Agent's address shown above or at such other place as Bank may designate in 
writing. All payments and prepayments made by the Borrower hereunder shall be 
made to the Agent, in immediately available funds, before 11:00 a.m. (Central 
Time) on the day that such payment is required, or otherwise is, to be made. 
Any payment received and accepted by the Agent after such time shall be 
considered for all purposes (including the calculation of interest, to the 
extent permitted by law) as having been made on the next following Business 
Day. Whenever any payment to be made hereunder falls on a day other than a 
Business Day, then unless otherwise provided in the Credit Agreement such 
payment shall be made on the next succeeding Business Day, and such extension 
of time shall in each case be included in the calculation of interest.

VARIABLE INTEREST RATE(S). This Note bears interest on and after the date hereof
to and including the Maturity Date at the variable rate(s) per annum equal to
the Prime Rate or LIBO Rate, as selected by Borrower in accordance with the
Credit Agreement. The interest rate on this Note is subject to change from time
to time based on changes in the Prime Rate and the LIBO Rate. If the index rate
used in determining the Prime Rate becomes unavailable during the term of this
Note, Agent may designate a substitute index after notice to Borrower. Agent
will tell Borrower the Prime Rate upon Borrower's request. Borrower understands
that Bank may make loans based on other rates as well. The interest rate change
will not occur more often than each day. The unpaid principal balance of this
Note shall bear interest from and after an Event of Default or the
Maturity Date until paid at the Default Rate from time to time in effect.

PREPAYMENT. Borrower may prepay this Note in full by paying the then unpaid
principal balance of this Note, plus accrued simple interest through date of
prepayment, subject to restrictions regarding permitted timing (with respect to
LIBO Rate Advances) and advance notice set forth in the Credit Agreement.
Borrower may be required to prepay this Note from time to time in accordance
with the Credit Agreement.

                                       -3-

EVENT OF DEFAULT. If any Event of Default occurs, Agent and Bank shall have 
all of the rights and remedies (including acceleration of the Maturity Date 
of this Note) available to them pursuant to the Credit Agreement or 
applicable law.

ATTORNEY'S FEES. If Bank refers this Note to an attorney for collection, or 
files suit against Borrower to collect this Note, or if Borrower files for 
bankruptcy or other relief from creditors, Borrower agrees to pay the Agent's 
and the Bank's reasonable attorneys' fees.

DEPOSIT ACCOUNTS. As collateral for repayment of this Note and all renewals 
and extensions, as well as to secure any and all other Indebtedness that 
Borrower may now and in the future owe to Agent or any Bank in connection 
with the Credit Agreement, Borrower hereby grants Agent for itself and the 
ratable benefit of the Banks a continuing security interest in any and all 
funds that Borrower may now and in the future have on deposit with Agent or 
in certificates of deposit or other deposit accounts as to which Borrower is 
an account holder (with the exception of any funds held in any of Borrower's 
accounts in trust for third parties, or funds held in IRA, pension, and other 
tax-deferred deposits).

GOVERNING LAW. BORROWER AGREES THAT THIS NOTE AND THE LOAN EVIDENCED HEREBY
SHALL BE GOVERNED UNDER THE LAWS OF THE STATE OF LOUISIANA. SPECIFICALLY, THIS
BUSINESS OR COMMERCIAL NOTE IS SUBJECT TO LA. R.S. 9:3509 ET SEQ.

COLLATERAL. This Note is secured by the Collateral Documents described in the
Credit Agreement.

WAIVERS. Borrower waives presentment for payment, protest, notice of protest and
notice of nonpayment, diligence in taking any action to collect amounts called
for hereunder and in the handling of property at any time existing as security
in connection herewith, and shall be directly and primarily liable for the
payment of all sums owing and to be owing hereon, regardless of and without any
notice, diligence, act or omission as or with respect to the collection of any
amount called for hereunder or in connection with any right, lien, interest or
property at any and all times had or existing as security for any amount called
for hereunder.

USURY CONSIDERATIONS. It is the intention of Borrower to conform strictly to
applicable usury laws. Accordingly, if the transactions contemplated hereby
would be usurious under applicable law (excluding applicable Louisiana law),
then, in that event notwithstanding anything to the contrary in any agreement
entered into as security for this Note, it is agreed as follows: (i) the
aggregate of all interest that is taken, reserved, contracted for, charged or

<PAGE>


                                       -4-

received under this Note or under any of the other aforesaid agreements or 
otherwise in connection with this Note shall under no circumstances exceed 
the maximum amount of interest allowed by applicable law, and any excess 
shall be credited on this Note by the holder hereof (or if the Note shall 
have been paid in full, refunded to Borrower); and (ii) in the event that 
maturity of this Note is accelerated by reason of default hereunder or 
otherwise, or in the event of any permitted prepayment, then such 
consideration that constitutes interest may never include more than the 
maximum amount allowed by applicable law, and excess interest, if any, 
provided for in this Note or otherwise shall be cancelled automatically as of 
the date of such acceleration or prepayment and, if theretofore prepaid, 
shall be credited on this Note (or if this Note shall have been paid in full, 
refunded to Borrower). To the extent that Louisiana law would be deemed the 
applicable law (as is the intent of Borrower hereunder), the provisions of 
the Section 2.8 in the Credit Agreement entitled DEFAULT RATE shall control.

               Surcharges and Fees in The Tariff, as such surcharges may be 
               changed from time to time.

             Shipper, Transporter shall be entitled to the difference, if

             of The Tariff, FERC ruling, or otherwise) to collect the 
             Approved Rate. Transporter and Shipper shall negotiate an 
             amendment to this Agreement or other arrangement which places the 
             Parties in the same economic position they would have been in 
             had Transporter been permitted to collect the full Approved Rate.

     Re:  Amendment to the Letter Agreement dated March 21, 1994, between CIG 
          and Amoco Energy Trading Corporation ("Picketwire Letter Agreement")

Ladies and Gentlemen:

     The following sets forth the agreement between Colorado Interstate Gas 
Company (CIG) and Amoco Energy Trading Corporation ("AETC"). In consideration 
of the mutual promises of the parties, CIG and AETC agree as follows:

1.   The provisions of the "Term--" section on pages 2 and 3 of the 
Picketwire Letter Agreement are deleted and replaced with the following:

     The term of the FTSA shall commence on December 1, 1994 and shall 
     continue through November 30, 2004.

2.   The term "$.0316 per Dth" in the first paragraph under "Rate--" on 
page 3 of the Picketwire Letter Agreement is deleted and replaced with 
the term "$.0245 per Dth."

3.   The second paragraph under "Rate--" on page 3 of the Picketwire Letter 
Agreement (which begins "AETC shall immediately submit to CIG...") is deleted.

4.   The paragraph under "Primary Point of Delivery--" on page 5 of the 
Picketwire Letter Agreement is deleted and replaced with the following:

     The initial MDQ (up to 3,160 Dth/d) shall have a Primary Point of 
     Delivery of Forgan. Any additional MDQ shall have a Primary Point of 
     Delivery of Dumas. Provided that if capacity to Forgan hereafter becomes 
     available, CIG shall post such capacity on its electronic bulletin 
     board. If, pursuant to the terms of CIG's FERC Gas Tariff, AETC acquires 
     capacity to Forgan for such additional MDQ, then the Primary Point of 
     Delivery for such additional MDQ shall be changed to Forgan.

5.   AETC and CIG shall execute an amendment to the Firm Transportation 
Service Agreement described in Paragraph 2 of the Picketwire Letter Agreement 
("FTSA"), to be effective November 1, 1997, which provides as follows:

<PAGE>

[LETTERHEAD]

(a)  The MDQ under the FTSA shall increase by 2,850 Dth/d (i.e., to a total 
     of 6,010 Dth/d).

(b)  The incremental MDQ of 2,850 Dth/d shall have a Primary Point of 
     Delivery of Dumas.

(c)  The rate for service to Dumas shall be $0.2877/Dth (computed on a 100% 
     load factor basis) plus fuel, L&U, GRI (if applicable) and ACA.

6.   Except as amended hereby and by the amendment to the FTSA described 
herein, the terms and provisions of the Picketwire Letter Agreement and the 
FTSA shall remain in full force and effect.

     If the foregoing is acceptable to AETC, please execute both originals of 
this letter agreement and return one to my attention at CIG.

                                   Sincerely,
                                   COLORADO INTERSTATE GAS COMPANY

     Clarification of Agreement

Dear Dennis:

This is to reaffirm the agreement of Colorado Interstate Gas Company ("CIG") 
and Amoco Energy Trading Corporation ("AETC") regarding the referenced Letter 
Agreement. The Letter Agreement contains various provisions which govern 
transportation services to be provided by CIG and AETC, and the Firm 
Transportation Service Agreement ("FTSA") is expressly subject to the terms 
of the Letter Agreement.

Paragraph five of page six of the Letter Agreement states that the terms of 
the FTSA are subject to the terms and conditions of the Letter Agreement 
and that the FTSA shall be amended from time to time in order to conform to 
the terms and conditions of the Letter Agreement. By execution of this 
amendment, it is further understood that in the event of conflict between the 
terms and provisions of the FTSA as altered by Amendment dated December 1, 
1994, or other Amendments entered into from time to time and the Letter 
Agreement, that the terms and provisions of the Letter Agreement shall 
prevail.

If the foregoing is in accordance with AETC's understanding, please so 
indicate by executing in the space provided below.

                                   Sincerely,

Dear Mr. Asheim:

The Transmission & Storage division of Colorado Interstate Gas Company (CIG) 
is concerned with the number of late payments for invoiced business since 
restructuring under Order 636.

Accordingly, effective with bills due on or after March 20, 1995, CIG will 
implement a late charge in accordance with Paragraph 11.3, Original Sheet No. 
331, of its Tariff. This charge will apply to any amounts unpaid (for 
services and cashouts) as of March 20, 1995. The late charge will be the FERC 
interest rate, however, without quarterly compounding. Of course, in the 
event that there is a billing error in your favor, CIG will refund the 
principal plus interest calculated in the same manner.

Should you have a dispute or questions regarding our invoices, we could ask 
that you address these to your Account Representative within 30 days and 
provide adequate supporting documentation.

We regret that this action has become necessary but feel that the situation 
should quickly correct itself once these Tariff provisions are implemented.

Sincerely,

/s/ Donald J. Zinko

Memo to Contract No. 178,074:


Per telecon with Craig Coombs (CIG) on December 2, 1994, it is not necessary 
to submit the $10,000 filing fee (deposit) pursuant to paragraph 2 of Rate 
provision on page 3 of the Letter Agreement dated March 21, 1994 between AETC 
and CIG. Amoco submitted a $10,000 fee for the initial 2,850 MDQ, and has the 
first right of refusal on an additional 2,850 of firm capacity on the 
Picketwire Lateral. The Picketwire Lateral is a 10" extension of CIG's 
mainline and has an approximate capacity of 50,000 Mcfd.

Re: Picketwire Lateral

Dear Gary:

This letter summarizes our verbal discussion between AETC and CIG on several 
matters relating to the Picketwire Lateral.

First, it is understood that AETC will install the necessary inert blending 
to meet CIG's upper Wobbe number limit of 1272. AETC may use air for such 
blending between now and January 1, 1996 provided the total amount of gas 
flowing on the Picketwire Lateral is not greater than 11,000 Dth/d. In the 
event volumes on the Picketwire Lateral are in excess of 11,000 Dth/d during 
this period then CIG will have the right to curtail such excess volumes. 
However, CIG will not curtail volumes less than AETC's current MDQ of 2850 
Dth. CIG shall accept gas above 950 Btu/Scf and below this upper Wobbe number 
limit. CIG will accept AETC's gas above the 1272 upper Wobbe number limit 
until January 15, 1995. This should allow adequate time for AETC to install 
their blending. AETC will install a Precision Measurement Model CB 2000 Therm 
Titrator as part of these facilities to be used for continuous control and 
subsequent shutdown in the event AETC does not meet the aforementioned 
requirements. CIG will reimburse AETC for the cost of this Therm Titrator 
since it was not stated as being required by CIG in the original March 21, 
1994 Letter Agreement between AETC and CIG.

Second, CIG will be sending a check to AETC in the amount of $173,590 to 
reimburse AETC for payments AETC made to CIG for CIG to proceed on 
preliminary work done on the Picketwire Lateral during late 1988 and early 
1989. The agreement between Amoco Production Company and CIG stipulates that 
CIG will repay AETC these amounts in the event CIG constructs the Picketwire 
Lateral.

Third, CIG will pursue presently a proposal to AETC and other third party 
producers on the Picketwire Lateral for central blending by CIG.

appreciated in these matters.

Gentlemen:


     We have audited the estimates, prepared by Evergreen Resources, Inc.
("Evergreen"), of the extent and value of the proved reserves of crude oil,
natural gas, and natural gas liquids for certain leases owned by Evergreen, as
of December 31, 1998. The appraised properties are located in Colorado. The
reserve estimates are prepared according to applicable SEC rules and utilize
conventional and generally accepted engineering methods.


     Our review of Evergreen's reserve estimates is based upon a study of
Evergreen's properties. During this investigation, we consulted with the
officers and employees of Evergreen and were given access to such accounts,
records, geological and engineering reports, and other data as were desired for
examination. We previously have prepared studies of oil and gas properties in
areas where Evergreen's properties are located. Property interests owned,
production from such properties, current prices for production, agreements
relating to current and future operations and sale of production, gas tax credit
sales agreements, and various other information and data were furnished to 
RSII by Evergreen and are accepted as factual without independent 
verification of such facts. We did not make a field examination of the 
operations or physical condition of the appraised properties.


     Natural gas reserves included in this report are classified as proved and
are judged to be economically producible in future years from known reservoirs
under existing economic and operating conditions, assuming continuation of the
current regulatory practices, and using conventional production methods and
equipment.


     Definitions of proved reserves used in this evaluation are those set forth
in Rule 4-10(a) of Regulation S-X, as adopted by the SEC:

          "PROVED OIL AND GAS RESERVES. Proved oil and gas reserves are the
     estimated quantities of crude oil, natural gas, and natural gas liquids
     which geological and engineering data demonstrate with reasonable certainty
     to be recoverable in future years from known reservoirs under existing
     economic and operating conditions, i.e., prices and costs as of the date
     the estimate is made. Prices include consideration of changes in existing
     prices provided only by contractual arrangements, but not on escalations
     based upon future conditions.

Evergreen Resources, Inc.

          "(i) Reserves are considered proved if economic producibility is
     supported by either actual production or conclusive formation tests. The
     area of a reservoir considered proved includes (A) that portion delineated
     by drilling and defined by gas-oil and/or oil-water contacts, if any, and
     (B) the immediately adjoining portions not yet drilled, but which can be
     reasonably judged as economically productive on the basis of available
     geological and engineering data. In the absence of information on fluid
     contacts, the lowest known structural occurrence of hydrocarbons controls
     the lower proved limit of the reservoir.

          "(ii) Reserves which can be produced economically through application
     of improved recovery techniques (such as fluid injection) are included in
     the 'proved' classification when successful testing by a pilot project, or
     the operation of an installed program in the reservoir, provides support
     for the engineering analysis on which the project or program was based.

          "(iii) Estimates of proved reserves do not include the following: (A)
     oil that may become available from known reservoirs but is classified
     separately as 'indicated additional reserves'; (B) crude oil, natural gas,
     and natural gas liquids, the recovery of which is subject to reasonable
     doubt because of uncertainty as to geology, reservoir characteristics, or
     economic factors; (C) crude oil, natural gas, and natural gas liquids, that
     may occur in undrilled prospects; and (D) crude oil, natural gas, and
     natural gas liquids, that may be recovered from oil shales, gilsonite and
     other such sources.

          "PROVED DEVELOPED OIL AND GAS RESERVES. Proved developed oil and gas
     reserves are reserves that can be expected to be recovered through existing
     wells with existing equipment and operating methods. Additional oil and gas
     expected to be obtained through the application of fluid injection or other
     improved recovery techniques for supplementing the natural forces and
     mechanisms of primary recovery should be included as 'proved developed
     reserves' only after testing by a pilot project or after the operation of
     an installed program has confirmed through production response that
     increased recovery will be achieved."

          "PROVED UNDEVELOPED AND GAS RESERVES. Proved undeveloped oil and gas
     reserves are reserves that are expected to be recovered from new wells on
     undrilled acreage, or from existing wells where a relatively major
     expenditure is required for recompletion. Reserves on undrilled acreage
     shall be limited to those drilling units offsetting productive units that
     are reasonably certain of production when drilled. Proved reserves for
     other undrilled units can be claimed only where it can be demonstrated with
     certainty that there is continuity of production from the existing
     productive formation. Under no circumstances should estimates for proved

     undeveloped reserves be attributable to any acreage for which an
     application of fluid injection or other improved recovery technique is
     contemplated unless such techniques have been proved effective by actual
     tests in the area and in the same reservoir."

     Natural gas volumes are expressed at standard conditions of temperature and
pressure applicable in the area the gas is purchased. Condensate reserves
estimated are those obtained from normal separator recovery. Crude oil is stated
as standard barrels of 42 U.S. gallons per barrel.

     Value of net proved reserves is expressed in terms of estimated future net
revenue and present value of future net revenue. Future net revenue is
calculated by deducting estimated operating expenses, future development costs,
and severance and ad valorem taxes from the future gross revenue.

     Present value of future net revenue is calculated by discounting the future
net revenue at the arbitrary rate of 10 percent per year compounded monthly over
the expected period of realization. Present value, as expressed herein, should
not be construed as fair market value since no consideration has been given to
many factors which influence the prices at which petroleum properties are
traded, such as taxes on operating profits, allowance for return on the
investment, and normal risks incident to the oil business.

     Evergreen has increased proven reserves from the August 31, 1998 report by
ongoing drilling which continues to prove additional locations. Remedial work on
wells, gathering system, and additional compression, must be completed to
produce the volumes forecast in this report. This work is in progress and should
be completed during the next 15 months. The capital investment for this work is
reflected in this report.

     Evergreen's gas reserves are coal gas located in the Raton Basin, Colorado.
Projection of coalbed methane gas reserves is generally more complicated than
projection of conventional hydrocarbon reservoirs due to complex reservoir
properties and the dewatering process required to develop producible natural gas
reservoirs. Therefore, reserve estimates and gas production rates for coalbed
methane wells are modified frequently as gas and water production data becomes
available.

     Resource Services International, Inc. and its principals are unrelated to
Evergreen, its officers, shareholders, and properties evaluated in this report.

Dear Mr. Sexton:

     In accordance with your request, we have audited the estimates prepared
by Evergreen Resources, Inc. (Evergreen), as of December 31, 1998, of the proved
reserves and future net revenue to the Evergreen interest in certain oil and gas
properties located in Las Animas County, Colorado. These estimates are based on
constant prices and costs. The following table sets forth Evergreen's estimates
of the proved reserves and future net revenue, as of December 31, 1998, for the
audited properties:

     Gas volumes are expressed in millions of standard cubic feet (MMCF) at the
contract temperature and pressure bases. These properties have never produced
commercial volumes of condensate.

     When compared on a property-by-property basis, some of the estimates of
Evergreen are greater and some are lesser than the estimates of Netherland,
Sewell & Associates, Inc.; however, in our opinion, Evergreen's estimates of net
proved oil and gas reserves and future net revenue, as shown herein and in
certain computer printouts on file in our office, are in the aggregate
reasonable and have been prepared in accordance with generally accepted
petroleum engineering and evaluation principles. These principles are set forth
in the Standards Pertaining to the Estimating and Auditing of Oil and Gas
Reserve Information promulgated by the Society of Petroleum Engineers. We are
satisfied with the methods and procedures utilized by Evergreen in preparing the
December 31, 1998 net reserve and future net revenue estimates, and we saw
nothing of an unusual nature that would cause us to take exception with the
estimates, in the aggregate, as prepared by Evergreen.

     The estimated reserves and future revenue shown herein are for proved
developed producing, proved developed non-producing, and proved undeveloped
reserves. Evergreen's estimates do not

include value for probable or possible reserves which may exist for these
properties, nor do they include any consideration of undeveloped acreage beyond
those tracts for which undeveloped reserves have been estimated.

     The gas price used by Evergreen is $1.60 per MCF and is held constant
throughout the life of the properties. Evergreen's estimates of lease and well
operating costs are based on historical operating expense records. These costs
include direct lease and field level costs, but do not include overhead expenses
above the field level. Evergreen used direct lease and field level costs of
$1,025 per well per month for the first year of production, $725 per well per
month for the next 3 years, and $425 per well per month for the remaining well
life. The reductions account for the declining water production during the life
of the wells. A gathering fee of $0.055 per MCF is also included. Headquarters
general and administrative overhead expenses of Evergreen are not included.
Lease and well operating costs are held constant throughout the remaining life
of the properties. Evergreen's estimates of capital costs are included as
required for workovers, new development wells, and production equipment.

     It should be understood that our audit does not constitute a complete
reserve study of Evergreen's oil and gas properties. Our audit consisted of a
detailed review of properties making up 80 percent of the present worth for the
total proved reserves. In our audit, we accepted without independent
verification the accuracy and completeness of the historical information and
data furnished by Evergreen with respect to ownership interest, oil and gas
production, well test data, oil and gas prices, operating and development costs,
and any agreements relating to current and future operations of the properties
and sales of production. However, if in the course of our examination something
came to our attention which brought into question the validity or sufficiency of
any such information or data, we did not rely on such information or data until
we had satisfactorily resolved our questions relating thereto or had
independently verified such information or data.

     We are independent petroleum engineers, geologists, and geophysicists with
respect to Evergreen Resources, Inc. as provided in the Standards Pertaining to
the Estimating and Auditing of Oil and Gas Reserve Information promulgated by
the Society of Petroleum Engineers. We do not own an interest in these
properties and are not employed on a contingent basis.

                                  Very truly yours,

                                  /s/ Netherland, Sewell & Associates, Inc.
