                               PROSPECTUS SUMMARY

    THIS SUMMARY HIGHLIGHTS INFORMATION CONTAINED ELSEWHERE IN THIS PROSPECTUS.
IT IS NOT COMPLETE AND MAY NOT CONTAIN ALL OF THE INFORMATION THAT YOU SHOULD
CONSIDER BEFORE INVESTING IN THE COMMON STOCK OFFERED FOR RESALE THROUGH THIS
PROSPECTUS. YOU SHOULD READ THE ENTIRE PROSPECTUS CAREFULLY, INCLUDING THE "RISK
FACTORS" SECTION AND THE FINANCIAL STATEMENTS AND THE NOTES TO THOSE STATEMENTS.


PENNACO ENERGY, INC.



    Pennaco Energy, Inc. is an independent, development stage exploration and
production company. Our current operations are completely focused on the
acquisition, development and production of natural gas from coal bed methane
properties in the Rocky Mountain region of the United States. We are one of the
largest holders of oil and gas leases covering coal bed methane properties in
the Powder River Basin of northeastern Wyoming and southeastern Montana. As of
March 1, 1999, we owned oil and gas lease rights with respect to approximately
311,800 net acres in the Powder River Basin in northeastern Wyoming and
southeastern Montana.



    We initiated our drilling program on November 15, 1998 and had drilled 197
gross (176 net) wells by June 15, 1999. Gross wells represent the total number
of wells in which we have an interest. Net wells represent the aggregate net
working interest that we own in all of our wells. We have operated all of our
wells drilled to date. We plan to drill approximately 460 net coal bed methane
wells in 1999, although there can be no assurance that we will have sufficient
funds to drill all of these wells, that it will be economic to do so or that
these wells will ultimately be productive. The wells we have drilled to date
have each taken an average of three days to drill and are either producing or in
various stages of completion awaiting construction of gathering and compression
systems and connection to a pipeline.



    We have flow tested most of the 32 wells which were drilled as of December
31, 1998. These tests resulted in the calculation of proved non-producing
reserves as reviewed by our third party reserve engineers. At December 31, 1998,
we had estimated net proved reserves of 18.1 Bcfe, or billion cubic feet
equivalent, with present value of estimated future net revenues before income
taxes (utilizing a 10% discount rate) of $8.5 million and a standardized measure
of discounted future net cash flows of $6.1 million. Natural gas constituted
100% of our estimated net proved reserves, all of which were located in the
Powder River Basin and 30% of which were developed but non-producing at
year-end. We operate all of the wells on our proved developed properties.



    We commenced initial gas production in April of 1999. Our net working
interest gas production is approximately 11 MMcf, or million cubic feet, per day
from 94 producing wells. While we believe that we have assembled an attractive
acreage position, we cannot guarantee that our acreage contains significant
amounts of natural gas reserves nor that our reserves can or will be
economically developed.


CMS TRANSACTION

    On October 23, 1998, we signed a definitive purchase and sale agreement with
CMS Energy Corporation's exploration and production unit, CMS Oil and Gas
Company, whereby CMS Oil and Gas Company acquired an undivided 50% working
interest in approximately 492,000 net acres of our leasehold position in the
Powder River Basin for $28 million in cash. The first closing occurred on
November 20, 1998 and the second closing occurred on January 15, 1999. We
acquired the leasehold position which was conveyed to CMS in the CMS transaction
for approximately $7.0 million. Since the announcement of our agreement with CMS
in October 1998, the jointly owned leasehold contained in the area of mutual
interest has increased from 492,000 net acres to approximately 560,000 net acres
through additional acreage purchases.

    The CMS agreement provides for the development of our lease acreage within
the area of mutual interest with Pennaco and CMS each operating approximately
50% of the wells to be drilled. As is

                                       3
<PAGE>

customary in oil and gas leasehold transactions, the agreement provides for the
adjustment of the purchase price for title defects discovered prior to closing
and for the opportunity for one party to participate in acquisitions made by the
other party in the area of mutual interest defined in the agreement. As of July
6, 1999, $0.3 million of the proceeds remained in escrow in the event certain
title defects could not be cured. Under the terms of the agreement, we will also
receive from CMS approximately $0.5 million for CMS's share of approximately
68,000 net acres acquired by Pennaco in the area of mutual interest since the
announcement of the transaction. The agreement also provides for a preferential
purchase right to the other party in the event either CMS or Pennaco attempts to
sell all or a portion of its interest in the acreage covered by the agreement.
There is no preferential purchase right in the event that either party enters
into a merger, reorganization or consolidation. All of the leases in the area of
mutual interest are dedicated to CMS Gas Transmission and Storage, an affiliate
of CMS Oil and Gas, for gathering, compression and transportation.


GAS GATHERING, COMPRESSION, MARKETING AND TRANSPORTATION


    We plan to continue to focus our capital spending on drilling, well
completion, production and land acquisition activities rather than gas gathering
and compression operations. Accordingly, we will utilize third party gathering
services to gather, compress and transport our natural gas from the wellhead to
market in return for gathering and compression fees. We recently entered into an
agreement with Bear Paw Energy under which Bear Paw Energy will construct, own
and operate gas gathering systems as well as provide gas gathering and
compression services to Pennaco outside of the CMS area of mutual interest in
our South Gillette Area.



    Production growth in the Powder River Basin is currently impeded by a
natural gas pipeline bottleneck which restricts the movement of natural gas out
of the basin. Four pipeline construction and expansion projects which would
serve the Powder River Basin have been announced, and are reportedly in the
process of obtaining permits and acquiring rights of way. On December 23, 1998,
CMS Gas Transmission and Storage, Enron Capital and Trade Resources Corporation,
Western Gas and Colorado Interstate Gas Company, a subsidiary of The Coastal
Corporation, jointly announced the formation of Fort Union Gas Gathering, LLC.
Fort Union has announced plans to build a 106 mile, 24 inch gathering pipeline
to gather coal bed methane gas in the Powder River Basin for delivery to
interstate pipeline interconnects near Glenrock, Wyoming. The new gathering line
is expected to have an initial capacity of approximately 450 MMcf per day of
natural gas and can be expanded with additional compression to 700 MMcf per day.
The operations are scheduled to commence on or about September 1, 1999.


    In September 1998, KN Energy, Inc. and Devon Energy Corporation announced
the formation of Thunder Creek Gas Services LLC. Thunder Creek has announced its
intention to build a 126 mile, 24 inch gathering line capable of delivering up
to 450 MMcf per day of natural gas to multiple interstate pipelines near
Douglas, Wyoming. The operations are scheduled to commence in October 1999.

    Additionally, Wyoming Interstate Gas Company, a subsidiary of the Coastal
Corporation, has filed an application with the Federal Energy Regulatory
Commission to construct a new 143 mile, 24 inch natural gas pipeline known as
the Medicine Bow Lateral from Glenrock to Cheyenne, Wyoming where the line will
interconnect with several interstate pipelines which serve the mid-continent and
west coast regions of the U.S. as well as the central Colorado markets. The
Medicine Bow Lateral is scheduled to commence operations in December 1999,
subject to FERC approval, will have initial capacity of 260 MMcf per day and can
be expanded with additional compression to 390 MMcf per day.

    On March 30, 1999, Pennaco and CMS announced that Pennaco has entered into a
gas gathering agreement with CMS Continental Natural Gas, Inc., a wholly owned
subsidiary of CMS Energy Corporation. Under this agreement, CMS Continental will
provide gas gathering services to Pennaco and

                                       4
<PAGE>
CMS Oil and Gas Company within the Pennaco/CMS area of mutual interest, which
excludes our South Gillette Area. CMS also announced plans to construct a $190
million, 110 mile high pressure gathering pipeline through the Pennaco/CMS
jointly owned acreage in the northern Powder River Basin coal bed methane play,
connecting at its southern terminus with the Fort Union pipeline project.


    Under the terms of the 15 year agreement, CMS Continental will charge
Pennaco a fixed fee per Mcf to gather, compress and transport our gas production
from each central metering facility located adjacent to each group or pod of 15
to 20 producing wells to the Fort Union gas gathering system. The fee varies by
well location within the area of mutual interest. CMS Continental's gathering
system is required to meet various performance measures subject to penalties for
under-performance. If CMS Continental elects not to connect a particular well or
group of wells, we have the right to connect the well or wells at our own cost
and adjust the fixed fee accordingly or allow a third party to do so.


    There can be no assurance that any of these gathering and pipeline systems
will ultimately be constructed or that they will be completed in the time-frame
currently anticipated.

RECENT DEVELOPMENTS


    1999 REVISED CAPITAL SPENDING PLAN



    On June 16, 1999, we announced a revised capital spending budget of $26.5
million for 1999, all of which will be directed toward our Powder River Basin
coal bed methane project. The revised budget represents an $8.1 million, or 44%,
increase over our former budget of $18.4 million. We plan to spend approximately
$18.0 million to drill approximately 460 net wells in the project area during
1999. These wells will be a combination of joint Pennaco/CMS wells drilled in
the area of mutual interest and Pennaco wells drilled outside the area of mutual
interest. Approximately $8.5 million is allocated to additional lease
acquisition. We will need additional funding to supplement the cash on our
balance sheet and internal cash flow in order to execute the announced capital
spending plans for 1999.



    BANK CREDIT FACILITY



    On June 29, 1999, we announced that we have received a commitment letter
from U.S. Bank National Association to make available to Pennaco a $25 million
revolving credit facility. The revolver will be a borrowing base facility
secured by our coal bed methane properties and will have an initial borrowing
capacity of $10 million. We expect to close this facility with U.S. Bank in July
1999, subject to customary closing conditions. We will utilize the bank facility
to supplement cash on our balance sheet and internal cash flow in order to fund
our revised 1999 capital spending plan.


    We currently maintain our principal executive offices at 1050 17th Street,
Suite 700, Denver, Colorado 80265. Our telephone number is (303) 629-6700 and
the facsimile number is (303) 629-6800. We also maintain an office at 3651
Lindell Road, Suite A, Las Vegas, Nevada 89103 and a field office at 400 South
Miller Avenue, Gillette, Wyoming 82716.

                                  RISK FACTORS

    AN INVESTMENT IN OUR COMPANY INVOLVES A SIGNIFICANT DEGREE OF RISK. YOU
SHOULD GIVE CAREFUL CONSIDERATION TO THE SPECIFIC FACTORS SET FORTH BELOW, AS
WELL AS THE OTHER INFORMATION SET FORTH IN THIS PROSPECTUS, BEFORE YOU PURCHASE
THE COMMON STOCK OFFERED IN THIS PROSPECTUS.

WE ARE A NEW COMPANY AND HAVE NO OPERATING HISTORY UPON WHICH TO BASE AN
  ASSUMPTION THAT WE WILL ACHIEVE OUR BUSINESS GOALS.


    We are a development stage company and had no revenues or income until
recently and we are subject to all the risks inherent in the creation of a new
business. Since our principal activities to date have been limited to
organizational activities, prospect development, acquisition of leasehold
interests, commencement of a drilling program and construction of gathering and
compression facilities, we have no record of any revenue-producing operations.
Consequently, there is no operating history upon which to base an assumption
that we will be able to successfully implement our business plans.


WE DEPEND ON GATHERING, COMPRESSION AND TRANSPORTATION FACILITIES TO MARKET OUR
  PRODUCTION AND WE CANNOT GUARANTEE THAT THESE FACILITIES WILL BE AVAILABLE
  WHEN NEEDED.


    The marketability of our natural gas production will depend in part upon the
availability, proximity and capacity of gas gathering and compression systems,
pipelines and eventually, processing facilities. Pipeline demand in the area is
increasing as coal bed methane development activity continues to expand. Our
core land position is located in an area near the development activity and
production. We have entered into an agreement with CMS Continental Natural Gas,
Inc. whereby CMS Continental will gather, compress and transport our gas within
the Pennaco/CMS area of mutual interest. We have entered into an agreement with
Bear Paw Energy whereby Bear Paw will construct well connection facilities as
well as gather, compress and transport our gas in the South Gillette Area which
lies outside of the Pennaco/CMS area of mutual interest. See "Prospectus
Summary--Gas Gathering, Compression, Marketing and Transportation". There is
limited pipeline capacity to transport gas out of the Powder River Basin which
will require expansion and new construction to accommodate the increasing
production. The expansion of the pipeline capacity is likely to require
significant capital outlays by the pipeline companies and the related plans and
specifications are subject to government regulatory review, permits and
approvals. This approval process may result in delays in the commencement and
completion of any pipeline construction project. We cannot guarantee that
certain of our wells will not be shut in for significant periods of time due to
the lack of capacity in existing pipelines. Further, we cannot guarantee that
any additional pipeline capacity will be completed on a timely basis or that we
will be permitted to transport any volumes via the additional capacity.


WE FACE RISKS RELATED TO THE LEASES WE ENTER INTO THAT MAY RESULT IN ADDITIONAL
  COSTS.

    It is customary in the oil and gas industry to acquire a lease interest in a
property based upon a preliminary title investigation. If the title to the
leases we plan to acquire are defective, we could lose the money already spent
on acquisition and development, or incur substantial costs to repair the title
defect. Our oil and gas leases give us the right to develop and produce oil and
gas from the leased properties. It is possible that the terms of our oil and gas
leases may be interpreted differently depending on the state in which the
property is located. For instance, royalty calculations can be substantially
different from state to state, depending on each state's interpretation of lease
language concerning the costs of production. We believe we have followed
industry standards in interpreting our oil and gas leases in the states where we
operate. However, we cannot guarantee that there will be no litigation
concerning the proper interpretation of the terms of our leases. Adverse
decisions in such litigation could result in material costs or the loss of one
or more leases.

THE VOLATILITY OF OIL AND GAS MARKETS MAY AFFECT OUR BUSINESS.

    If we begin production, our revenues, profitability and future rate of
growth will be substantially dependent upon prevailing market prices for natural
gas and oil, which can be extremely volatile and in

                                       6
<PAGE>
recent years have been depressed at times by excess domestic and imported
supplies. In addition to market factors, actions of state and local agencies,
the United States and foreign governments, and international cartels affect oil
and gas prices. All of these factors are beyond our control. These external
factors and the volatile nature of the energy markets make it difficult to
estimate future prices of natural gas and oil. We cannot guarantee that we will
be able to produce oil or gas on an economic basis in light of prevailing market
prices. If we are able to produce natural gas, any substantial or extended
decline in the price of natural gas would have a material adverse effect on our
financial condition and results of operations, including reduced cash flow and
borrowing capacity and could reduce both the value and the amount of our oil and
gas reserves.

WE FACE COMPETITION FROM OTHER COMPANIES IN THE NATURAL GAS BUSINESS AND FOR THE
  ACQUISITION OF SUITABLE PROPERTIES.

    Competition to acquire properties is intense. We compete with a number of
potential purchasers that possess greater financial resources than are available
to us. Different companies evaluate potential acquisitions differently. This
results in widely differing bids. If other bidders are willing to pay higher
prices than we believe are supported by our evaluation criteria, then our
ability to acquire prospects could be limited. Low or uncertain prices for
properties could cause potential sellers to withhold or withdraw properties from
the market. In such an environment, we cannot guarantee that there will be a
sufficient number of suitable prospects available for acquisition. Also, we may
be limited in our options for developing prospects.

    In addition to competition for leasehold acreage in the Powder River Basin,
the oil and gas exploration and production industry is intensely competitive as
a whole. We will compete against established companies that have significantly
greater financial, marketing, personnel, and other resources than us. Such
competition could have a material adverse effect on our ability to execute our
business plan and our profitability.

SHUT-IN WELLS, CURTAILED PRODUCTION, AND OTHER PRODUCTION INTERRUPTIONS MAY
  AFFECT OUR ABILITY TO DO BUSINESS.

    In the event that we initiate production and generate income from our coal
bed methane properties, such production may be curtailed or shut in for
considerable periods of time due to any one or a combination of the following
factors:

    - a lack of market demand;

    - government regulation;

    - pipeline and processing interruptions;

    - production allocations;

    - diminished pipeline capacity; and

    - force majeure.

    These curtailments may continue for a considerable period of time. There may
be an excess supply of gas in areas where our operations will be conducted. In
such an event, it is possible that there will be no market or a very limited
market if we do generate production in the future. There is also the possibility
that drilling rigs may not be available when needed and there may be shortages
of crews, equipment and other manpower requirements.

WE ARE SUBJECT TO OPERATING RISKS WHICH MAY NOT BE COVERED BY OUR INSURANCE.

    The oil and natural gas business involves certain operating hazards, such
as:

    - well blowouts;

    - craterings;

    - explosions;

                                       7
<PAGE>
    - 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 these hazards could cause us to suffer substantial losses if they
occur after we begin commercial production. In addition, we may be liable for
environmental damage caused by previous owners of the property we have purchased
or leased. 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 or cause us to
suffer losses. In accordance with customary industry practices, we maintain
insurance against some, but not all, of such risks and losses. We currently
carry well control insurance as well as property and general liability
insurance. We may elect to self-insure if our 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 our financial condition and
results of operations. In addition, pollution and environmental risks generally
are not fully insurable.

OUR DRILLING ACTIVITIES MAY PRODUCE UNDRINKABLE WATER THAT MUST BE TREATED OR
  REINJECTED WHICH WILL INCREASE OUR COSTS.

    If during the course of drilling activity undrinkable water is discovered,
it may be necessary to install and operate evaporators or to drill disposal
wells to reinject the produced water back into the underground rock formations
adjacent to the coal seams or to lower sandstone horizons. In the event we are
unable to obtain the appropriate permits, undrinkable water is discovered or if
applicable laws or regulations require water to be disposed of in an alternative
manner, the costs to dispose of produced water will increase and these costs
could have a material adverse effect on our operations in this area and the
profitability of such operations including rendering future production and
development uneconomic.

OUR INDUSTRY IS SUBJECT TO EXTENSIVE REGULATION WHICH MAY INCREASE OUR COSTS.

    The oil and gas industry is extensively regulated by federal, state and
local authorities. Legislation and regulations affecting the industry are under
constant review for amendment or expansion, raising the possibility of changes
that may affect, among other things, the pricing or marketing of oil and gas
production. Substantial penalties may be assessed for noncompliance with various
applicable statutes and regulations, and the overall regulatory burden on the
industry increases our cost of doing business and, in turn, decreases our
profitability.

WE DO NOT ANTICIPATE PAYING DIVIDENDS IN THE FORESEEABLE FUTURE.

    At the present time, we do not anticipate paying dividends, cash or
otherwise, on our common stock in the foreseeable future. Future dividends will
depend on the presence or absence of earnings, our financial requirements and
other factors. If you anticipate the need for immediate income from your
investment, you should refrain from purchasing the securities offered by this
prospectus.

                               PLAN OF OPERATION


    The following information should be read in conjunction with the financial
statements and notes to the financial statements presented elsewhere in this
prospectus. We follow the successful efforts method of accounting for oil and
gas properties. See "Organization and Summary of Accounting Policies," included
in Note 1 of the consolidated financial statements.


GENERAL


    As a development stage company, we had no revenues from operations in 1998
or in the three months ended March 31, 1999. During the period from our
inception on January 26, 1998 through March 31, 1999, we reported net income of
$3,199,687. We realized a gain on sale of properties of $13,358,764 based on the
$26,824,767 of proceeds received in the first and second closing of the CMS
transaction which occurred on November 20, 1998 and January 15, 1999,
respectively. Expenses incurred from our inception through March 31, 1999
totaled $7,673,766, including general and administrative expenses of $5,022,379
and exploration expenses of $1,877,357, including geologic consulting fees,
geologic data and lease rentals. During the three month period ended March 31,
1999, we reported net income of $7,012,560. We realized a gain on the sale of
properties of $11,945,557 received in the second closing of the CMS transaction.
Expenses incurred during the three month period ended March 31, 1999 totaled
$1,126,400 including general and administrative expenses of $1,044,787 and
exploration expenses of $51,590, including geologic consulting fees, geologic
data and lease rentals.



    In the accompanying financial statements, in accordance with APB No. 25
"Accounting for Stock Issued to Employees," we have recognized a non-cash charge
to earnings for compensation expense of approximately $1,790,000 for the period
from our inception through December 31, 1998 for stock, warrants, and options
issued to certain officers and employees. Compensation expense was calculated
based on the difference between the closing price per share on the last trading
day prior to the date of employment with Pennaco and the $1.75 unit price for
shares and warrants purchased by one of our officers hired at the beginning of
July and the option price for options awarded to officers and key employees
hired in July and August 1998. The restricted securities were offered as an
incentive to attract a senior management team. We believe that the offers made
by the Board of Directors were at fair market value due to the restricted nature
of the securities to be issued and the lack of a liquid trading market for the
our common stock at the time of the offer. However, APB No. 25 requires the
measurement of compensation expense at the date of employment rather than at the
offer date. Further, APB No. 25 requires that compensation be measured based on
the quoted market price of the stock once a company's stock is publicly traded.
While we were not an SEC registrant until September 8, 1998, our shares have
been quoted on the OTC Bulletin Board System since July 1, 1998.


LIQUIDITY AND CAPITAL RESOURCES


    Our capital resources are limited. Until April 1999, we had not produced any
revenues and our main source of funds has been the sale of our equity securities
and proceeds from CMS Transaction. We had approximately $10.4 million in cash as
of March 31, 1999.



    On December 23, 1998, we announced an agreement with CMS Oil and Gas
Company. Under the terms of this agreement, CMS paid us $5.6 million in the form
of a bridge loan secured by substantially all of our oil and gas leases.
Approximately $3.2 million of this amount was paid directly to our existing
creditors. We used the balance for general corporate purposes. We received $7.6
million at the first closing on November 20, 1998 and $14.8 million at the
second closing on January 15, 1999 less approximately $1.8 million which was
deposited into an escrow account subject to customary closing adjustments. The
CMS bridge loan was canceled at the second closing. Pro forma for the CMS
transaction as of December 31, 1998, we had no debt and approximately $19.8
million of cash. As of July 6, 1999, approximately $0.3 million remained in
escrow pending closing adjustments for the CMS transaction. The proceeds of the
CMS transaction allowed us to repay our current liabilities and should allow us
to fund a portion of our


                                       11
<PAGE>

planned $26.5 million capital expenditure program for 1999. We will require
further funding to meet our future expenditure plans.



    Should our cash flow from operations be insufficient to satisfy our planned
capital expenditure requirements, we cannot guarantee that additional debt or
equity financing will be available to meet these requirements. We are presently
in the process of closing a $25 million bank credit facility with U.S. Bank. The
bank credit facility will be secured by substantially all of our coal bed
methane properties and will have an initial borrowing base of $10 million. We
cannot guarantee that we will be successful in closing the bank facility or that
the facility will provide us with sufficient borrowing capacity to execute our
future capital spending plans.



    The level of debt we assume will have several important effects on our
future operations, including (1) a substantial portion of our cash flow could be
dedicated to the payment of interest on its indebtedness and would not be
available for other purposes and (2) our ability to obtain additional financing
in the future may be impaired. To address the operational and administrative
requirements of our ongoing development activities, we anticipate that during
the next 12 months employee requirements will increase to approximately 20
employees. Currently, we have 16 full-time employees.


CAPITAL EXPENDITURES


    We had capital expenditures of approximately $6.7 million in the first
quarter of 1999, including approximately $2.7 million for lease acquisitions and
$3.9 million for drilling activities. On June 16, 1999, we announced a revised
capital spending budget of $26.5 million for 1999, all of which will be directed
towards our Powder River Basin coal bed methane project. The revised budget
represents an $8.1 million, or 44%, increase over our former budget of $18.4
million. We plan to spend approximately $18.0 million to drill approximately 460
net wells in the Powder River Basin during 1999, although we cannot guarantee
that we will have sufficient funds to drill all of these wells, that it would be
economic to do so or that these wells will ultimately be productive. The wells
will be a combination of joint Pennaco/CMS wells drilled in the area of mutual
interest and Pennaco wells drilled primarily on a 100% working interest basis
located outside of the Pennaco/CMS area of mutual interest. The balance of the
1999 capital budget, approximately $8.5 million, is allocated to lease
acquisition. We are in the process of closing a bank credit facility secured by
our coal bed methane properties which will be utilized in addition to our cash
reserves and internal cash flow to execute the revised 1999 capital spending
budget.

                                    BUSINESS

GENERAL


    We are an independent, development stage exploration and production company.
Our current operations are completely focused on the acquisition, development
and production of natural gas from coal bed methane properties in the Rocky
Mountain region of the United States. We are one of the largest holders of oil
and gas leases covering coal bed methane properties in the Powder River Basin in
northeastern Wyoming and southeastern Montana. As of March 1, 1999, we owned oil
and gas lease rights with respect to approximately 311,800 net acres in the
Powder River Basin.



    The coal bed methane wells in the Powder River Basin are generally 350 to
1,200 feet in depth and typically take only two or three days to drill and
complete. Because of the relatively shallow depth and short amount of time to
drill a well, coal bed methane wells have relatively low drilling, completion
and well connection costs. These costs typically amount to $60,000 to $70,000
per well. Approximately 50% of the total well costs are well connection costs,
comprised of costs of gathering lines, power lines and surface equipment. In
order to conserve our capital, we plan to contract much of the well connection
cost to third party gatherers in return for payment of a per Mcf, or thousand
cubic feet, gathering fee. The coal bed methane gas recovered from the wells in
the Powder River Basin does not require processing but does require dehydration
and compression and could eventually require carbon dioxide treatment over the
next several years.



    We initiated our drilling program on November 15, 1998 and had drilled
approximately 32 gross (30 net) wells as of December 31, 1998. We have operated
all of our wells drilled to date. As of June 15, 1999, we had drilled
approximately 197 gross (176 net) coal bed methane wells and plan to drill
approximately 460 net coal bed methane wells in 1999, although we cannot
guarantee that we will have sufficient funds to drill all of these wells, that
it will be economic to do so or that these wells will ultimately be productive.
The wells we have drilled to date have each taken an average of three days to
drill and are in various stages of completion and testing while awaiting
construction of gathering and compression systems and connection to a pipeline.



    We have flow tested most of the 32 wells drilled as of December 31, 1998.
These tests resulted in the calculation of proved non-producing reserves as
reviewed by our third party engineers. At December 31, 1998, we had estimated
net proved reserves of 18.1 Bcfe with present value of estimated future net
revenues before income taxes (utilizing a 10% discount rate) of $8.5 million and
a standardized measure of discounted future net cash flows of $6.1 million.
Natural gas constituted 100% of our estimated net proved reserves, all of which
were located in the Powder River Basin and 30% of which were developed but non-
producing at year-end. We operate all of the wells on our proved developed
properties.



    The success of our drilling program, including the magnitude of any
potential reserves, cannot be fully evaluated until the wells are completed,
connected to a gathering system and produced for a period of time. We commenced
initial gas production in April 1999. Our net working interest gas production is
approximately 11 MMcf per day from 90 producing wells. We operate all of our
producing wells.



    We entered into an agreement with Bear Paw Energy, Inc., a subsidiary of
TransMontaigne, Inc., under which Bear Paw Energy will construct, own and
operate gas gathering systems as well as provide gas gathering and compression
services to Pennaco in our South Gillette Area. Under the terms of the agreement
with Bear Paw Energy, Bear Paw paid Pennaco approximately $1.0 million for
gathering and compression construction and equipment costs that we had incurred
to date and Bear Paw paid Pennaco a negotiated fixed fee per Mcf for gas
gathered, compressed and transported from the south Gillette Area. On March 17,
1999, we entered into an agreement with Western Gas Resources, Inc. to compress
and transport 11 MMcf per day of gas from the Dopplebock compressor station
located southwest of our South Gillette Area to the interconnect with Williston
Basin Interstate Pipeline at Recluse, Wyoming. Pennaco has entered into two gas
sale contracts to sell a total of 10,000 MMBtu, or million British thermal
units, (approximately 11 MMcf per day of production) per day of natural gas for
12 months beginning April 1, 1999 to two gas purchasers deliverable at Recluse,
Wyoming into the Williston pipeline. The purchasers


                                       13
<PAGE>

under these agreements, Interenergy Resources Corporation and Montana-Dakota
Utilities Co., will pay Pennaco a negotiated fixed rate per MMbtu for the
natural gas delivered under these agreements. We entered into agreements to
purchase gas for the months of April and May 1999 in order to supplement our
initial gas production and meet our gas sales contract obligations. We believe
that once gathering and compressions systems are completed, our initial
production from our South Gillette Area will be sufficient to satisfy our
obligations under these two gas sales contracts.



    We currently maintain our principal executive offices at 1050 17th Street,
Suite 700, Denver, Colorado 80265. Our telephone number is (303) 629-6700 and
our facsimile number is (303) 629-6800. We also maintain an office at 3651
Lindell Road, Suite A, Las Vegas, Nevada 89103 and a field office at 400 South
Miller Avenue, Gillette, Wyoming 82716.


CMS TRANSACTION


    On October 23, 1998, we signed a definitive purchase and sale agreement with
CMS Oil and Gas Company relating to the development of our Powder River Basin
acreage within a designated area of mutual interest. Pursuant to the terms of
the CMS agreement, CMS acquired an undivided 50% working interest in
approximately 492,000 net acres of our leasehold position in the Powder River
Basin for $28.0 million. We acquired that portion of the leasehold position
which was conveyed to CMS in the CMS transaction for approximately $7.0 million.
The purchase price provided for in the CMS agreement was the result of arm's
length negotiations between Pennaco and CMS and was also a function of the
consideration we originally paid for the acreage. Our Board of Directors
received a fairness opinion from Hanifen Imhoff, Inc. that the CMS transaction
was fair to our stockholders from a financial point of view. We compensated
Hanifen Imhoff, Inc. with a fee of $125,000 for rendering this fairness opinion.



    Since the announcement of the CMS transaction, the jointly owned leasehold
contained in the area of mutual interest has grown from 492,000 net acres to
approximately 560,000 net acres through additional acreage purchases. The CMS
agreement provides for the development of our leasehold acreage within the area
of mutual interest, with Pennaco and CMS each operating approximately 50% of the
wells to be drilled. As is customary in oil and gas leasehold transactions, the
agreement provides for the adjustment of the purchase price for title defects
discovered prior to closing and for the opportunity for one party to participate
in acquisitions made by the other party in the area of mutual interest defined
in the agreement. As of June 25, 1999, approximately $0.3 million of the
proceeds of the CMS transaction remained in escrow pending resolution of
possible title defects. Under the terms of the agreement, we will also receive
approximately $0.5 million from CMS for their share of approximately 68,000 net
acres acquired by Pennaco in the area of mutual interest since the announcement
of the transaction. The agreement provides for a preferential purchase right to
the other party in the event either CMS or Pennaco attempts to sell a portion of
its interest in the acreage covered by the agreement. There is no preferential
purchase right in the event that either party enters into a merger,
reorganization or consolidation. All of the leases in the area of mutual
interest are dedicated to CMS Gas Transmission and Storage, an affiliate of CMS,
for gathering, compression and transportation, provided that such services are
offered at competitive market rates.


BUSINESS STRATEGY


    Our business strategy is to build an exploration and production company that
is focused on creating value for our stockholders through profitable growth in
reserves, production and cash flow per share. The key components of our business
strategy include the following.



    - Focus activities in the Powder River Basin coal bed methane project.



    - Allocate approximately 70% of drilling expenditures to lower risk
      development.



    - Drive acreage consolidation in the Powder River Basin.



    - Outsource gas gathering, compression and transportation operations.


                                       14
<PAGE>

    - Continue to build high quality management and technical teams.


    - Acquire additional undeveloped properties in the Powder River Basin that
      add to near-term drilling inventory.


    - Seek to acquire operating control and majority ownership interests in
      properties to optimize the timing and efficiency of operations.



    - Maintain a strong balance sheet and diversify capital sources in order to
      be in a position to capitalize on opportunities as they occur.


GAS GATHERING, COMPRESSION, MARKETING AND TRANSPORTATION


    Production growth in the Powder River Basin is currently impeded by a
natural gas pipeline bottleneck which restricts the movement of natural gas out
of the basin. Currently only two pipelines are available to transport coal bed
methane gas out of the Powder River Basin. The MIGC pipeline, which is operated
by Western Gas, has recently undergone a 40 MMcf per day expansion to 130 MMcf
per day. The MIGC line runs south through the eastern side of the Powder River
Basin to interconnect with two interstate pipelines near Glenrock, Wyoming, but
has little available capacity due to increasing coal bed methane gas production
from the Powder River Basin. A subsidiary of MDU Resources operates the 42 MMcf
per day Williston Basin Interstate pipeline which runs northeast from Recluse,
Wyoming to local markets throughout eastern Montana and North Dakota and
interconnects with the Northern Border pipeline, an interstate pipeline which
travels southeast to the Chicago markets. The Williston Basin Interstate
pipeline has limited additional capacity.



    Three pipeline construction and expansion projects which would serve the
Powder River Basin have been announced, all of which are reportedly in the
process of obtaining permits and acquiring rights of way. On December 23, 1998,
CMS Gas Transmission and Storage, Enron Capital and Trade Resources Corporation,
Western Gas and Colorado Interstate Gas Company, a subsidiary of The Coastal
Corporation, jointly announced the formation of Fort Union Gas Gathering, LLC.
Fort Union has announced plans to build a 106 mile, 24 inch gathering pipeline
to gather coal bed methane gas in the Powder River Basin. The new gathering line
is expected to have an initial capacity of approximately 450 MMcf per day of
natural gas and can be expanded with additional compression to 700 MMcf per day.
The Fort Union line is expected to deliver coal bed methane gas to a carbon
dioxide treating facility to be constructed near Glenrock, Wyoming and to
interstate pipeline interconnects near Glenrock. The operations are scheduled to
commence on or about September 1, 1999, although we cannot guarantee that the
system will ultimately be constructed or that it will be completed in the
time--frame currently anticipated.



    In September 1998, KN Energy, Inc. and Devon Energy Corporation announced
the formation of Thunder Creek Gas Services LLC. Thunder Creek has announced its
intention to build a 126 mile, 24 inch gathering line capable of delivering up
to 450 MMcf per day of natural gas to multiple interstate pipelines near
Douglas, Wyoming. The operations are scheduled to commence in October 1999,
although we cannot guarantee that the system will ultimately be construed or
that it will be completed in the time-frame currently anticipated.



    Wyoming Interstate Gas Company, a subsidiary of the Coastal Corporation, has
filed an application with the Federal Energy Regulatory Commission to construct
a new 143 mile, 24 inch natural gas pipeline known as the Medicine Bow Lateral
from Glenrock to Cheyenne, Wyoming where the line will interconnect with several
interstate pipelines which serve the mid-continent and west coast regions of the
U.S. as well as the central Colorado markets. The Medicine Bow Lateral is
scheduled to commence operations in December 1999, subject to FERC approval,
will have initial capacity of 260 MMcf per day of natural gas and can be
expanded with additional compression to 390 MMcf per day. We cannot guarantee
that the system will ultimately be constructed or that it will be completed in
the time-frame currently anticipated.



    We have focused our initial capital spending on drilling, well completion,
production and land acquisition activities rather than gas gathering and
compression operations. Accordingly, we are utilizing


                                       15
<PAGE>

third party gathering services to gather, compress and transport our natural gas
from the wellhead to market in return for gathering and compression fees. We
have entered into an agreement with Bear Paw Energy under which Bear Paw Energy
will construct, own and operate gas gathering systems as well as provide gas
gathering and compression services to Pennaco outside of the Pennaco/CMS area of
mutual interest in our South Gillette Area. Under the terms of the agreement,
Bear Paw Energy will charge Pennaco a fixed per Mcf fee to gather, compress and
transport our gas production from the wellhead to various delivery points. The
fee varies by delivery point and amount of compression. Bear Paw Energy's
gathering system is required to meet various performance measures subject to
penalty for underperformance. If Bear Paw elects not to connect a particular
well or group of wells, we have the right to construct the gathering system
ourselves or allow a third party to do so.



    On March 16, 1999 we entered into a ten year gathering and compression
agreement with Western Gas Resources. Under the terms of the agreement, Western
Gas will compress and transport 11 MMcf per day of gas from the Doppelbock
compressor station located southwest of our South Gillette Area to the
interconnect with the Williston Basin Interstate pipeline at Recluse, Wyoming
for a negotiated fixed fee per Mcf. Western Gas will take delivery of a portion
of the gas gathered by Bear Paw Energy in the South Gillette Area and transport
the gas to Doppelbock.



    On March 30, 1999, Pennaco and CMS announced that Pennaco has entered into a
gas gathering agreement with CMS Continental Natural Gas, Inc., a wholly owned
subsidiary of CMS Energy Corporation. Under this agreement, CMS Continental will
provide gas gathering services to Pennaco and CMS Oil and Gas Company within the
Pennaco/CMS area of mutual interest, which excludes our South Gillette Area. CMS
also announced plans to construct a $190 million, 110 mile high pressure
gathering pipeline through the Pennaco/CMS jointly owned acreage in the northern
Powder River Basin coal bed methane play, connecting at its southern terminus
with the Fort Union pipeline project.



    Under the terms of a 15 year agreement, CMS Continental will charge Pennaco
a negotiated fixed fee per Mcf to gather, compress and transport our gas
production from each central metering facility located adjacent to each group or
pod of 15 to 20 producing wells, to the Fort Union gas gathering system. The fee
varies by well location within the area of mutual interest. CMS Continental's
gathering system is required to meet various performance measures subject to
penalties for under-performance. If CMS Continental elects not to connect a
particular well or group of wells, we have the right to connect the well or
wells at our own cost and adjust the fixed fee accordingly or allow a third
party to do so.



    On November 11, 1998, we entered into a gas brokerage and administration
agreement with Mercator Energy, Inc. whereby Mercator agreed to provide gas
marketing and gas administration services to Pennaco. This agreement was renewed
on March 1, 1999 and extends until September 1, 1999 and converts to a
month-to-month basis thereafter. Mercator has extensive experience in gas
marketing services in the Rocky Mountain region and specifically in the Powder
River and surrounding gas producing basins.


COMPETITION


    We compete with a number of other potential purchasers of oil and gas leases
and producing properties, many of which have greater financial resources than we
do. The bidding for oil and gas leases has become particularly intense in the
Powder River Basin with bidders evaluating potential acquisitions with varying
product pricing parameters and other criteria that result in widely divergent
bid prices. The presence of bidders willing to pay prices higher than are
supported by our evaluation criteria could further limit our ability to acquire
oil and gas leases. In addition, low or uncertain prices for properties can
cause potential sellers to withhold or withdraw properties from the market. In
this environment, we cannot guarantee that there will be a sufficient number of
suitable oil and gas leases available for acquisition or that we can sell oil
and gas leases or obtain financing for or participants to join in the
development of prospects.



    In addition to competition for leasehold acreage in the Powder River Basin,
the oil and gas exploration and production industry is intensely competitive as
a whole. We compete against well-


                                       16
<PAGE>

established companies that have significantly greater financial, marketing,
personnel and other resources than us. This competition could have a material
adverse effect on our ability to execute our business plan and our
profitability.


REGULATION

    GENERAL


    Our operations are affected by numerous governmental laws and regulations
including energy, environmental, conservation, tax and other laws and
regulations relating to the energy industry. Many departments and agencies, both
federal and state, are authorized by statute to issue and have issued rules and
regulations binding on the oil and natural gas industry and its individual
participants. Changes in any of these laws and regulations could have a material
adverse effect on our business. In view of the many uncertainties with respect
to current and future laws and regulations, including their applicability to
Pennaco, we cannot predict the overall effect of such laws and regulations on
its future operations.



    We believe that our 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 our method of operations
than on other similar companies in the energy industry.



    OPERATIONS ON FEDERAL OR STATE LEASES



    Our operations on federal or state oil and gas leases will be subject to a
number of restrictions, including nondiscrimination statutes. These operations
are subject to a variety of on-site security regulations and other permits and
authorizations issued by the Bureau of Land Management, Minerals Management
Service and other agencies. In order to drill wells in Wyoming on federal, state
or privately-owned land, we are required to file an Application for Permit to
Drill with the Wyoming Oil and Gas Commission. Drilling on acreage controlled by
the federal government requires the filing of a similar application with the
BLM. While we have been able to obtain required drilling permits to date, we
cannot guarantee that permitting requirements will not adversely effect our
ability to complete our drilling program at the cost and in the time period
currently anticipated.



    Drilling on federal lands in a large portion of the Powder River Basin is
currently limited until the completion of an environmental impact statement, or
EIS, by the BLM. The number of drilling permits allowed on federal lands subject
to the EIS are limited until the EIS is complete. This limitation could
adversely affect our ability to drill on federal lands. Approximately 53% of our
leasehold is comprised of federal acreage although only a portion of our acreage
is currently included in the EIS. Operators are currently drilling wells on an
interim basis on federal lands with the limited number of drilling permits
allowed by the BLM until the EIS is complete. We have approximately 38 interim
drilling permits on federal lands within the EIS. The EIS was originally
scheduled for completion in May 1999, but has been delayed until September 1999.
We cannot guarantee the ultimate completion date of the EIS.


    TRANSPORTATION AND SALE OF NATURAL GAS


    The FERC regulates interstate natural gas pipeline transportation rates as
well as the terms and conditions of service. FERC's regulations will affect the
marketing of any natural gas produced by us, as well as any revenues we receive
for sales of natural gas. In 1985, the FERC adopted policies that make natural
gas transportation accessible to natural gas buyers and sellers on an
open-access, nondiscriminatory basis. The FERC issued Order No. 636 on April 8,
1992, which, among other things, prohibits interstate pipelines from making
sales of gas tied to the provision of other services and requires pipelines to
"unbundle" the services they provide. This has enabled buyers to obtain natural
gas supplies from any source and secure independent delivery service from the
pipelines. All of the interstate pipelines subject to FERC's jurisdiction are
now operating under Order No. 636, open access tariffs. On July 29, 1998, the
FERC issued a Notice of Proposed Rulemaking regarding the regulation of short
term natural gas transportation services. FERC proposes to revise its
regulations to require all available short term capacity


                                       17
<PAGE>
(including capacity released by shippers holding firm entitlements) to be
allocated through an auction process. FERC also proposes to require pipelines to
offer additional services under open access principles, such as "park and loan"
services. In a related initiative, FERC issued a Notice of Inquiry on July 29,
1998 seeking input from natural gas industry players and affected entities
regarding virtually every aspect of the regulation of interstate natural gas
transportation services. Among other things, FERC is seeking input on whether to
retain cost-based rate regulation for long term transportation services,
potential changes in the manner in which rates are designed, and the use of
index driven or incentive rates for pipelines. The July 29, 1998 Notice of
Inquiry may lead to a subsequent Notice of Proposed Rulemaking to further revise
FERC's regulations.


    Additional proposals and proceedings that might affect the natural gas
industry are considered from time to time by Congress, the FERC, state
regulatory bodies and the courts. We cannot predict when or if any such
proposals might become effective or their effect, if any, on our operations. The
natural gas industry historically has been closely regulated. Accordingly, we
cannot guarantee that the less stringent regulatory approach recently pursued by
the FERC and Congress will continue indefinitely into the future.


    PRODUCTION


    The production of oil and natural gas is subject to regulation under a wide
range of state and federal statutes, rules, orders and regulations. State and
federal statutes and regulations require permits for drilling operations,
drilling bonds and reports concerning operations. Wyoming and Montana have
regulations governing conservation matters, including provisions for the
unitization or pooling of oil and natural gas properties, the establishment of
maximum rates of production from oil and natural gas wells and the regulation of
the spacing, plugging and abandonment of wells. The effect of these regulations
is to limit the amount of oil and natural gas that we can produce from our wells
and to limit the number of wells or the locations at which we can drill.
Additionally, each state generally imposes a production or severance tax with
respect to production and sale of crude oil, natural gas and gas liquids within
its jurisdiction.


    ENVIRONMENTAL REGULATIONS


    Various federal, state and local laws and regulations governing the
discharge of materials into the environment, or otherwise relating to the
protection of the environment, will affect our operations and costs. In
particular, our exploration, development and production operations, its
activities in connection with storage and transportation of liquid hydrocarbons
and its use of facilities for treating, processing or otherwise handling
hydrocarbons and wastes therefrom will be subject to stringent environmental
regulation. Because coal bed methane wells typically produce significant amounts
of water, we are required to file applications with state and federal
authorities, as applicable, to enable us to dispose of water produced from its
wells. While we have been able to obtain required water disposal permits to
date, we cannot guarantee that permitting requirements will not negatively
affect our ability to complete our drilling and development program at the cost
and in the time period currently anticipated.



    As with the energy industry generally, compliance with existing regulations
will increase our overall cost of doing business. These costs include production
expenses primarily related to the control and limitation of air emissions and
the disposal of produced water, capital costs to drill exploration and
development wells resulting from expenses primarily related to the management
and disposal of drilling fluids and other oil and gas exploration wastes and
capital costs to construct, maintain and upgrade production equipment and
facilities.



    The Comprehensive Environmental Response, Compensation and Liability Act,
which is commonly referred to as CERCLA and is also known as "Superfund",
imposes liability, without regard to fault or the legality of the original act,
on classes of persons that contributed to the release of a "hazardous substance"
into the environment. These persons include the "owner" or "operator" of the
site and companies that disposed or arranged for the disposal of the hazardous
substances found at the site. CERCLA also authorizes the Environmental
Protection Agency and, in some instances, third parties, to act in response to
threats to the public health or the environment and to seek to recover from the
responsible classes of


                                       18
<PAGE>

persons the costs they incur. In the course of its ordinary operations, we may
generate waste that may fall within CERCLA's definition of a "hazardous
substance." We may be jointly and severally liable under CERCLA for all or part
of the costs required to clean up sites at which such wastes have been disposed.



    We may own or lease properties that have been used for the exploration and
production of hydrocarbons in the past. Many of these properties will have been
owned by third parties whose actions with respect to the treatment and disposal
or release of hydrocarbons or other wastes were not under our control. These
properties and wastes disposed thereon may be subject to CERCLA and analogous
state laws. Under these laws, we could be required to remove or remediate
previously disposed wastes, including wastes disposed of or released by prior
owners or operators, to clean up contaminated property, including contaminated
groundwater; or to perform remedial plugging operations to prevent future
contamination.


EMPLOYEES


    We currently have 16 full-time employees and utilize the services of
approximately 10 consulting geologists, engineers, and land acquisition
professionals. We plan to hire additional employees as needed. We have an
outsourcing arrangement with Trinity Petroleum Management, LLC which provides
for administrative services, specifically land administration and accounting.
The Trinity agreement is effective until August 31, 1999 when it converts to a
month-to-month arrangement. We believe that by outsourcing various
administrative functions to Trinity we are able to hire fewer full-time
employees and more efficiently control our administrative expenses.


CUSTOMERS


    During 1998, we made no sales of natural gas. We have entered into two
natural gas sales contracts with a term of one year each beginning April 1,
1999. One contract for 5,000 MMBtu per day is with Interenergy Resources
Corporation, an affiliate of KN Energy, Inc. and the other, also for 5,000 MMBtu
per day, is with Montana-Dakota Utilities Co., a division of MDU Resources
Group, Inc. We are dependent on these two customers to purchase our initial
production, particularly until the completion of the Fort Union gathering
project which is scheduled to commence operations on September 1, 1999 and the
Thunder Creek gathering project which is scheduled to commence operations in
October 1999.


PREDECESSOR ENTITIES


    We were formed under the laws of the State of Nevada on January 26, 1998, to
engage in the business of oil and gas exploration, production and marketing. Our
original predecessor was incorporated on March 12, 1985 as VCI Video
Communications, Inc. in the Province of British Columbia and subsequently
changed its name to AKA Video Communications, Inc. On March 25, 1996 the
shareholders of AKA Video agreed to exchange all AKA Video shares for shares of
International Metal Protection, Inc., our immediate predecessor. After this
exchange AKA Video became inactive and the directors and shareholders approved
the windup of AKA Video. International Metal was incorporated on March 5, 1996,
in the State of Wyoming. Following an exchange of all the International Metal
outstanding shares in a share for share exchange with Pennaco, International
Metal was dissolved in February of 1998. We are the sole surviving entity of the
reorganization.



LEGAL PROCEEDINGS



    We may be subject from time to time to routine litigation in connection with
our oil and gas operations. Currently the Company is not involved in litigation
which could have a material impact on the Company.

                            DESCRIPTION OF PROPERTY

OPERATIONS


    We initiated our drilling program on November 15, 1998 and had drilled
approximately 32 gross (30 net) wells as of December 31, 1998. As of June 15,
1999, we had drilled approximately 197 gross (176 net) coal bed methane wells
and plan to drill approximately 460 net coal bed methane wells in 1999. We
cannot, however, guarantee that we will have sufficient funds to drill all of
these wells, that it would be commercially reasonable to drill all of these
wells or that these wells will ultimately be productive. All of the wells
drilled to date have been operated by Pennaco. The wells we have drilled to date
have each taken an average of three days to drill and are in various stages of
completion and testing while awaiting construction of gathering and compression
systems and connection to a pipeline. The success of our drilling program,
including the magnitude of any potential reserves, cannot be determined until
the wells are completed, connected to a gathering system and produced for a
period of time.



    Our ability to complete our drilling program is entirely dependent upon the
availability of sufficient capital, equipment and personnel. The estimated total
cost per well is approximately $60,000 to $70,000 to drill, complete and install
well connection facilities. The estimated drilling portion of the total per well
cost is approximately $10,000 per well.



    We have entered into a drilling agreement with CBM Drilling, LLC, pursuant
to which we had prepaid drilling costs of $333,473 as of December 31, 1998.
Based on the agreement that every third well shall be drilled at no cost to
Pennaco, the prepaid drilling costs will be recovered after approximately 100
additional net wells are drilled for Pennaco by CBM Drilling. The prepayments to
CBM Drilling were made to ensure that drilling rigs appropriate for coal bed
methane drilling operations will be available and dedicated to the Company's
planned drilling program. CBM Drilling currently has four coal bed methane
drilling rigs, three of which are primarily dedicated to our drilling program.



    Approximately 50% of the average $60,000 to $70,000 total well cost is well
connection cost comprised of gathering lines, power lines and surface equipment.
In the South Gillette Area where we have drilled most of our 135 wells drilled
as of March 22, 1999, we have entered into a gas gathering and compression
agreement with Bear Paw Energy that also provides for well connection services
in return for a per Mcf gathering fee. Accordingly, we have reduced our average
well costs in the South Gillette Area to approximately $30,000 per well in
return for a comprehensive well connection, gathering and compression fee. In
the South Gillette Area, Bear Paw Energy will construct, own and operate all
gathering and compression facilities from the wellhead to the interconnect with
MIGC, Fort Union or Thunder Creek pipelines. We intend to continue to allocate
our capital expenditures to drilling, completion and lease acquisition
activities rather than well connection, gathering and compression activities.

</TABLE>



    In accordance with SEC requirements, estimates of our proved reserves and
future net revenues are made using sales prices estimated to be in effect as of
the date of such reserve estimates and are held constant throughout the life of
the properties, except to the extent a contract specifically provides for
escalation. Estimated quantities of proved reserves and future net revenues
therefrom are affected by natural gas and oil prices, which have fluctuated
widely in recent years. There are numerous uncertainties inherent in estimating
natural gas and oil reserves and their estimated values, including many factors
beyond the control of the producer. The reserve data set forth in this document
represents only estimates. Reservoir engineering is a subjective process of
estimating underground accumulation of natural gas and oil that cannot be
measured in an exact manner. The accuracy of any reserve estimate is a function
of the quality of available data and of engineering and geological
interpretation and judgment. As a result, estimates of different engineers,
including those used by Pennaco, may vary. In addition, estimates of reserves
are subject to revision based upon actual production, results of future
development and exploration activities, prevailing natural gas and oil prices,
operating costs and other factors, which revisions may be material. Accordingly,
reserve estimates are often different from the quantities of natural gas and oil
that are ultimately recovered and are highly dependent upon the accuracy of the
assumptions upon which they are based.



    In general, the volume of production from natural gas properties we own
declines as reserves are depleted. Except to the extent we acquire additional
properties containing proved reserves or conduct successful exploration and
development activities, or both, our proved reserves will decline as reserves
are produced. Volumes generated from our future activities are therefore highly
dependent upon the level of success in acquiring or finding additional reserves
and the costs incurred in doing so.



    You should read Note 9--"Information Regarding Proved Oil and Gas
Reserves--Unaudited" to the Financial Statements included in this document for
additional information pertaining to our proved natural gas reserves as of
December 31, 1998.


PRODUCTION


    We had no oil and gas production in 1998. We commenced natural gas
production in April 1999. See "Item 1--Description of Business--General". Our
current net working interest gas production is approximately 11 MMcf per day
from 90 producing wells.

(1) Held by production acreage is leasehold interest in oil and gas properties,
    which is beyond its primary term and is being kept in force by virtue of
    production of oil and gas in commercial quantities.


(2) Pro forma to give effect to the closing of the CMS transaction which
    occurred on January 15, 1999. See "Item 1--Description of Business--CMS
    Transaction." Approximately 20,000 net undeveloped acres are subject to an
    election to purchase on behalf of CMS pursuant to the terms of the CMS
    transaction.


PROPERTIES


    Following the second closing of the CMS transaction on January 15, 1999, we
owned oil and gas leases covering approximately 304,934 net acres in the Powder
River Basin of Wyoming and Montana. Since the second closing, we have acquired
an additional 6,800 net acres outside of the Pennaco/CMS area of mutual
interest, increasing our leasehold total to approximately 311,800 net acres as
of March 1, 1999. Approximately 56% of the acreage is located on federal and
state land and approximately 44% of the acreage is located on private land. Our
leases generally have five to ten year primary terms. The federal leases are
generally ten year term leases and newly acquired fee and state leases are
generally five-year term leases.



    Our Powder River Basin leasehold can generally be divided into four separate
project areas as follows:



    SOUTH GILLETTE AREA--We now hold approximately 16,000 net acres in this
project area located near the town of Gillette, Wyoming and outside the CMS area
of mutual interest. We began our initial drilling program in this area and 180
of our 197 gas wells drilled as of June 15, 1999 are located here. We operate
all of our South Gillette Area wells which have an average 93% working interest.
The wells are either producing or are in the process of being tested, dewatered
and connected to gathering and compression systems. Our first gas production
began flowing from this area in April 1999.



    NORTHERN FAIRWAY AREA--We hold approximately 142,000 net acres in this
project area located north of the town of Gillette, Wyoming, up to the Wyoming
border on the east side of the basin. Virtually all of our leasehold acreage in
this area is included in the area of mutual interest with CMS. We drilled and
are the operator of 11 exploratory coal bed methane wells in the Spotted Horse
Prospect located in this area. We also drilled and are the operator of five
exploratory coal bed methane wells in the Collums Prospect. The wells in these
two prospects are in the process of completion and testing.



    BORDER AREA--We hold approximately 92,000 net acres in this project area
located in Montana adjoining the Wyoming border adjacent to the Northern Fairway
Area and the Sherian Area. All of our leasehold in this area is included in the
area of mutual interest with CMS. While we have not drilled any wells in this
area, some industry coal bed methane drilling activity has occurred adjacent to
the Border Area with encouraging results.


                                       23
<PAGE>

    SHERIDAN AREA--We hold approximately 62,000 net acres in this project area
located in Wyoming primarily east of the town of Sheridan on the west side of
the basin. Virtually all of our leasehold in this area is included in the area
of mutual interest with CMS. We have not drilled any wells in this area.



    Historically, oil and gas has been produced from a number of other
reservoirs in the Powder River Basin that are typically greater in depth than
coal bed methane locations. Over 75% of our leasehold acreage allow for
development of all depths. These leases cover both the shallow coal bed methane
and exploration potential for oil and gas from the deeper horizons. Past
exploration of the sedimentary section below the Paleocene coal section has
resulted in production from sandstone reservoirs in 25 formations from upper
Cretaceous to Pennsylvanian age. No such production has been generated from our
leases.


TITLE TO PROPERTIES


    As is customary in the oil and gas industry, only a preliminary title
examination is conducted at the time we acquire oil and gas leases covering
properties believed to be suitable for drilling operations. 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, we prepare a division order title report indicating the
proper parties and percentages for payment of production proceeds, including
royalties. We believe that title to our leasehold properties is good and
defensible in accordance with standards generally acceptable in the oil and gas
industry. Our properties are subject to customary royalty interests, liens
incident to operating agreements, liens for current taxes and other burdens
which we believe do not materially interfere with the use of or affect the value
of such properties.


OFFICE FACILITIES


    Our office space is currently subleased pursuant to an agreement with
Evansgroup, Inc. The term of the sublease commenced on April 6, 1998 and expires
on September 30, 2000. The sublease covers approximately 11,524 square feet at a
yearly rent of approximately $173,000.



    We also lease office and lodging space in Gillette, Wyoming. The lease
covers approximately 9,000 square feet at a yearly rent of approximately
$17,400. In February 1999 a new lease/purchase agreement was entered into
whereby the term of the lease/purchase agreement commences on April 4, 1999 and
expires December 31, 2000. The yearly rent is approximately $17,400. Under terms
of the purchase option, $1,000 per month of the rent is deemed to apply to a
purchase option on the property. The purchase option expires January 7, 2001.

(1) We recognized non-cash compensation expense relating to restricted common
    stock and warrants purchased by Mr. Warren of $675,000, and stock options
    issued to Mr. Dobkins of $556,250 and Mr. Kuhn of $412,500, respectively, in
    the third quarter of 1998. This non-cash expense was recognized in
    accordance with APB No. 25, "Accounting for Stock Issued to Employees."
    Compensation expense was calculated based on the difference between the
    closing price per share on the last trading day prior to the date of
    purchase and the $1.75 unit price for restricted shares and warrants
    purchased by Mr. Warren. Compensation expense for Mr. Dobkins and Mr. Kuhn
    was calculated based on the difference between the closing price per share
    on the last trading day prior to the date of employment and the exercise
    price for options awarded. The restricted securities were offered as
    incentive to attract a senior management team. We believe that the offers
    made by the Board of Directors in June 1999 were at market value due to the
    restricted nature of the securities to be issued and the lack of a liquid
    trading market for our common stock at the time the offers were made which
    was prior to the date that our stock was first quoted on the OTC Bulletin
    Board system. However, APB No. 25 requires the measurement of compensation
    expense at the date of employment rather than at the offer date. Further,
    APB No. 25 requires that compensation be measured based on the quoted market
    price of our stock once the stock is publicly traded. While we were not an
    SEC registrant until September 8, 1998, our shares were quoted on the OTC
    Bulletin Board system beginning July 1, 1998. Our shares were initially
    listed on the American Stock Exchange on April 19, 1999.


(2) Mr. Rady became an executive officer on June 16, 1998, compensated at an
    annual salary of $120,000.

(3) Mr. Warren became an executive officer on July 2, 1998, compensated at an
    annual salary of $100,000.

(4) Mr. Dobkins became an officer on July 6, 1998, compensated at an annual
    salary of $95,000.

(5) Mr. Kuhn became an officer on July 9, 1998, compensated at an annual salary
    of $87,000.

1998 STOCK OPTION AND INCENTIVE PLAN


    On March 24, 1998, the Board of Directors adopted the 1998 Stock Option and
Incentive Plan which was subsequently approved by our stockholders. Our
stockholders approved an amendment to the plan on June 29, 1998. The plan is
intended to provide incentive to key employees and directors of, and key
consultants, vendors, customers, and others


                                       29
<PAGE>

    - expected to provide significant services to Pennaco,



    - to encourage proprietary interest in Pennaco,



    - to encourage such key employees to remain in our employ,



    - to attract new employees with outstanding qualifications, and



    - to afford additional incentive to consultants, vendors, customers, and
      others to increase their efforts in providing significant services to the
      Company.



The plan is administered by the Board of Directors or can be administered by a
committee appointed by the Board of Directors, which committee shall be
constituted to permit the plan to comply with Rule 16b-3 of the Act, and which
shall consist of not less than two members. The Board of Directors, or the
committee if there is one, at its discretion, can select the eligible employees
and consultants to be granted awards, determine the number of shares to be
applicable to such award, and designate any options as incentive stock options
or nonstatutory stock options, except that no incentive stock option may be
granted to a non-employee director or a non-employee consultant. The stock
subject to awards granted under the plan are shares of our authorized but
unissued or reacquired common stock. The aggregate number of shares which may be
issued as awards or upon exercise of awards under the plan is 4,500,000 shares.
As of December 31, 1998, non-statutory stock options to purchase 2,969,365 have
been granted to key employees and directors for exercise prices ranging from
$1.25 to $5.00 per share pursuant to the vesting schedules of the respective
agreements. Options in the amount of 616,500 are vested as of December 31, 1998
while the balance of the options vest over the passage of time or are tied to
certain benchmarks being achieved with regards to the drilling of wells or
obtaining certain annual gross production revenues. The shares that may
presently be issued pursuant to the exercise of an option awarded by the plan
have not been registered under the Securities Act of 1933, any state securities
authority, nor any foreign securities authority, and will be subject to the
limitations of Rule 144.


    The following table reflects certain information regarding stock options
granted to the Named Executive Officers during the period ended December 31,
1998.

                              PLAN OF DISTRIBUTION


    We are registering the common stock on behalf of selling stockholders. As
used in this prospectus, "selling stockholders" includes donees and pledgees
selling shares received from a named selling stockholder after the date of this
prospectus. All costs, expenses and fees in connection with the registration of
the common stock offered hereby will be paid by us. Brokerage commissions and
similar selling expenses, if any, attributable to the sale of common stock will
be borne by the selling stockholders. Sales of common stock may be effected by
selling stockholders from time to time in one or more types of transactions
(which may include block transactions) through the American Stock Exchange, in
negotiated transactions, through put or call option transactions relating to the
common stock, through short sales of common stock, or a combination of such
methods of sale, at market prices prevailing at the time of sale, or at
negotiated prices. These transactions may or may not involve brokers or dealers.
The selling stockholders have advised us that they have not entered into any
agreements, understandings or arrangements with any underwriters or
broker-dealers regarding the sale of their securities, nor is there an
underwriter or coordinating broker acting in connection with the proposed sale
of common stock by the selling stockholders.



    The selling stockholders may sell common stock directly to purchasers or to
or through broker-dealers, which may act as agents or principals. These
broker-dealers may receive compensation in the form of discounts, concessions,
or commissions from the selling stockholders and/or purchasers of common stock
for whom such broker-dealers may act as agents or to whom they sell as
principal, or both. The compensation as to a particular broker-dealer might be
in excess of customary commissions.


                                       34
<PAGE>

    The selling stockholders and any broker-dealers that act in connection with
the sale of common stock might be deemed to be "underwriters" within the meaning
of Section 2(a)(11) of the Securities Act, and any commissions received by such
broker-dealers and any profit on the resale of the common stock sold by them
while acting as principals might be deemed to be underwriting discounts or
commissions under the Securities Act. We have agreed to indemnify each selling
stockholder against liabilities, including liabilities arising under the
Securities Act. The selling stockholders may agree to indemnify any agent,
dealer or broker-dealer that participates in transactions involving sales of the
common stock against certain liabilities, including liabilities arising under
the Securities Act.


    Because selling stockholders may be deemed to be "underwriters" within the
meaning of Section 2(a)(11) of the Securities Act, the selling stockholders will
be subject to the prospectus delivery requirements of the Securities Act. We
have informed the selling stockholders that the anti-manipulative provisions of
Regulation M promulgated under the Exchange Act may apply to their sales in the
market.


    Selling stockholders also may resell all or a portion of the common stock in
open market transactions in reliance upon Rule 144 under the Securities Act,
provided they meet the criteria and conform to the requirements of the Rule.



    When we are notified by a selling stockholder that any material arrangement
has been entered into with a broker-dealer for the sale of common stock, we will
file a supplement to this prospectus, if required, pursuant to Rule 424(b) under
the Act, disclosing


    - the name of each such selling stockholder and of the participating
      broker-dealer(s),


    - the number of shares of common stock involved,



    - the price at which such shares of common stock were sold,


    - the commissions paid or discounts or concessions allowed to such
      broker-dealer(s), where applicable,

    - that the broker-dealer(s) did not conduct any investigation to verify the
      information set out or incorporated by reference in this prospectus and

    - other facts, material to the transaction.

    In addition, when we are notified by a selling stockholder that a donee or
pledgee intends to sell more than 500 shares, a supplement to this prospectus
will be filed. See "Principal and Selling Stockholders."

    Some of the information that appears in this registration statement
regarding the December 31, 1998 estimated quantities of reserves of the

prepared by or derived from estimates prepared by Ryder Scott Company
independent petroleum engineers.

                                 LEGAL MATTERS


    The legality of the common stock offered by this prospectus will be passed

                 CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS


    David E. Coffey, C.P.A., the accounting firm that had previously been
engaged as the principal accountant to audit the Company's financial statements,
was dismissed in July 1998. Our Board of Directors approved the dismissal of
David E. Coffey, C.P.A. The audit report previously issued by David E. Coffey,
C.P.A. with respect to our financial statements did not contain an adverse
opinion or a disclaimer of opinion, nor was such report qualified or modified as
to uncertainty, audit scope or accounting principles. Our Board of Directors
approved the selection of KPMG LLP as auditors for our financial statements for
the period ending March 31, 1999, and KPMG LLP was engaged for such purpose in
September 1998.

The Board of Directors
Pennaco Energy, Inc.:

    We have audited the accompanying balance sheet of Pennaco Energy, Inc. (a
development stage company) as of December 31, 1998, and the related statements
of operations, stockholders' equity and cash flows for the period from January
26, 1998 (inception) to December 31, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audit.

    We conducted our audit 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 audit provides a reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Pennaco Energy, Inc. as of
December 31, 1998, and the results of its operations and its cash flows for the
period from January 26, 1998 (inception) to December 31, 1998, in conformity

                         NOTES TO FINANCIAL STATEMENTS

(1) ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    (a) ORGANIZATION AND BASIS OF PRESENTATION

       Pennaco Energy, Inc. (the "Company") is an independent energy company
       primarily engaged in the acquisition and development of natural gas
       production from coal bed methane properties in the Rocky Mountain region
       of the United States. The Company was incorporated on January 26, 1998
       under the laws of the state of Nevada and its headquarters are in Denver,
       Colorado.

       The Company's activities to date have been limited to organizational
       activities, prospect development activities, acquisition of leases and
       option rights, and commencement of its drilling program. The Company
       currently has oil and gas lease rights in the Powder River Basin in
       northeastern Wyoming and southeastern Montana. Currently the Company has
       no revenue producing operations. Accordingly, the Company is considered
       to be in the development stage.

       The Company was incorporated as a wholly-owned subsidiary of
       International Metal Protection Inc. ("International Metal").
       Subsequently, all of the outstanding shares of International Metal were
       exchanged for shares of the Company and International Metal was merged
       into the Company. The 995,000 shares issued in the exchange were recorded
       at their par value of $.001 per share as International Metal had no
       assets or liabilities at the date of the merger. International Metal and
       its predecessor, AKA Video Communications Inc., had been inactive for the
       two years ended December 31, 1997 and prior thereto.

    (b) USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

       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 in the financial
       statements and the reported amounts of revenues and expenses during the
       reporting period. Actual results could differ from those estimates.

    (c) SIGNIFICANT RISKS

       The Company is subject to a number of risks and uncertainties inherent in
       the oil and gas industry. Among these are risks related to fluctuating
       oil and gas prices, uncertainties related to the estimation of oil and
       gas reserves and the value of such reserves, effects of competition and
       extensive environmental regulation, risks associated with the search for
       and the development of oil and gas reserves, and many other factors, many
       of which are necessarily beyond the Company's control. The Company's
       financial condition and results of operations will depend significantly
       upon the Company's ability to find and develop natural gas and oil
       reserves and upon the prices received for natural gas and oil produced,
       if any. These prices are subject to fluctuations in response to changes
       in supply, market uncertainty and a variety of additional factors that
       are beyond the control of the Company.

    (d) CASH AND CASH EQUIVALENTS

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

(1) ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    (e) OIL AND GAS ACTIVITIES

       The Company follows the successful efforts method of accounting for its
       oil and gas activities. Accordingly, costs associated with the
       acquisition, drilling and equipping of successful exploratory wells are
       capitalized. Geological and geophysical costs, delay and surface rentals
       and drilling costs of unsuccessful exploratory wells are charged to
       expense as incurred. Costs of drilling development wells, both successful
       and unsuccessful, are capitalized. Upon the sale or retirement of oil and
       gas properties, the cost thereof and the accumulated depreciation and
       depletion are removed from the accounts and any gain or loss is credited
       or charged to operations. Upon the sale of a partial interest in an
       unproved property, the proceeds are treated as a recovery of cost. If the
       proceeds exceed the carrying amount of the property, a gain is recognized
       in operations. Depletion of capitalized acquisition, exploration and
       development costs is computed on the units-of-production method by
       individual fields as the related proved reserves are produced.

       Capitalized costs of unproved properties are assessed periodically and a
       provision for impairment is recorded, if necessary, through a charge to
       operations.

       Proved oil and gas properties are assessed for impairment on a
       field-by-field basis. If the net capitalized costs of proved oil and gas
       properties exceeds the estimated undiscounted future net cash flows from
       the property a provision for impairment is recorded to reduce the
       carrying value of the property to its estimated fair value.

    (f) OTHER PROPERTY AND EQUIPMENT

       Other property and equipment is recorded at cost. Depreciation and
       amortization is provided using the straight-line method over the
       estimated useful lives of the assets, which range from 3 to 15 years.

    (g) INCOME TAXES

       The Company provides for income taxes using the asset and liability
       method of accounting for income taxes. Under the asset and liability
       method, deferred tax assets and liabilities are recognized for the future
       tax consequences attributable to differences between the financial
       statement carrying amounts of existing assets and liabilities and their
       respective tax bases and net operating loss carryforwards. Deferred tax
       assets and liabilities are measured using enacted income tax rates
       expected to apply to taxable income in the years in which those
       differences are expected to be recovered or settled. Under the asset and
       liability method, the effect on deferred tax assets and liabilities of a
       change in income tax rates is recognized in the results of operations in
       the period that includes the enactment date.

    (h) STOCK-BASED COMPENSATION

       Statement of Financial Accounting Standards No. 123, ACCOUNTING FOR
       STOCK-BASED COMPENSATION (SFAS 123), defines a fair value method of
       accounting for stock compensation plans. SFAS 123 allows an entity to
       measure compensation costs for these plans using the intrinsic value
       based method of accounting as prescribed in Accounting Principles Board
       Opinion No. 25, ACCOUNTING

                               DECEMBER 31, 1998

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(1) ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
       FOR STOCK ISSUED TO EMPLOYEES (APB 25), which the Company has elected to
       follow. The pro forma disclosures of net loss and loss per share required
       by SFAS 123 are included in note 5.

    (i) LOSS PER SHARE

       Loss per share is based on the weighted average number of common shares
       outstanding during the period. Outstanding stock options and warrants
       were excluded from the computation as their effect was antidilutive.

(2) CMS TRANSACTION

    On October 23, 1998, the Company and CMS Oil and Gas Company signed a
    definitive agreement (the "CMS Agreement") relating to the development of
    the Company's Powder River Basin acreage (the "CMS Transaction"). Pursuant
    to the terms of the CMS Agreement, CMS Oil and Gas Company will acquire an
    undivided 50% working interest in approximately 492,000 net acres of
    Pennaco's leasehold position in the Powder River Basin for $28,000,000. The
    Company acquired the leasehold position which is being conveyed to CMS in
    the CMS Transaction for approximately $7,000,000. The purchase price
    provided for in the CMS Agreement was the result of arm's length
    negotiations between the Company and CMS. The joint operating agreement
    between the parties will be modeled after the 1989 AAPL Model Form of Joint
    Operating Agreement. The CMS Agreement provides that the parties will in
    good faith negotiate a development agreement for the exploration,
    development and production of coal bed methane from the leases. The
    development agreement will provide that each party will operate
    approximately 50% of the wells drilled in the area of mutual interest.
    Pennaco and CMS have divided the acreage in the area of mutual interest into
    project areas which will be operated by one party or the other. As is
    customary in oil and gas leasehold transactions, the agreement provides for
    the adjustment of the purchase price for title defects discovered prior to
    closing and for the opportunity for one party to participate in acquisitions
    made by the other party in the area of mutual interest defined in the
    agreement. The agreement also provides for a preferential purchase right to
    the other party in the event either CMS or the Company attempts to sell a
    portion of its interest in the acreage covered by the agreement. There is no
    preferential purchase right in the event that either party enters into a
    merger, reorganization or consolidation. All of the leases in the area of
    mutual interest are dedicated to CMS Gas Transmission and Storage, an
    affiliate of CMS Oil and Gas Company, for gathering, compression and
    transportation.

    Pursuant to the terms of the CMS Agreement, CMS agreed to pay Pennaco
    $5,600,000 of earnest money in the form of a non-interest bearing bridge
    loan (the "CMS Bridge Loan") which was secured by substantially all of the
    Company's oil and as leases. Approximately $3,200,000 of such amount was
    paid directly to existing creditors of the Company. The CMS Transaction is
    structured such that the conveyance of the working interests was to occur at
    two separate closings. The first closing occurred on November 20, 1998, and
    the second occurred on January 15, 1999. The Company received $7,600,000 at
    the first closing and received $14,800,000 at the second closing, less
    approximately $1,800,000 which is held in escrow subject to customary
    closing adjustments. As of March 12, 1999, approximately $1,200,000 was held
    in escrow pending CMS closing adjustments. The CMS Bridge Loan was canceled
    at the second closing.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(2) CMS TRANSACTION (CONTINUED)
    The unaudited pro forma balance sheet of the Company as of December 31, 1998
    gives effect to the sale of the interest in the properties and the use of a
    portion of the proceeds to repay the bridge loan and the lease acquisitions
    payable, all as if the transactions had occurred on that date.

(3) BRIDGE LOAN

    The Company borrowed $3,200,000 on September 4, 1998 under a bridge loan
    with interest payable at 18% per year. The bridge loan was paid in full on
    October 23, 1998 with proceeds from the CMS Transaction.

(4) INCOME TAXES

    The income tax benefit of $1,266,000 includes a deferred federal income tax
    benefit of $1,196,000 and a deferred state income tax benefit of $70,000.
    The income tax benefit recorded for the period from inception to December
    31, 1998 differs from the expected income tax benefit (based on the
    statutory rate of 34%) primarily as a result of state income taxes, and
    stock and stock option compensation which is not deductible for tax
    purposes.

    At December 31, 1998, the Company has a net operating loss carryforward for
    federal income tax purposes of approximately $431,000 which is available to
    offset future federal taxable income, if any, through 2018. The tax effects
    of temporary differences that give rise to the deferred tax assets at
    December 31, 1998, relate to the net operating loss carryforward.

(5) STOCKHOLDERS' EQUITY

    (a) COMMON STOCK

       Since its formation in January 1998, the Company completed four private
       placement offerings of common stock. In February 1998, 500,000 shares
       were issued at $.10 per share. Proceeds to the Company were approximately
       $50,000. Also in February 1998, 4,530,000 shares were issued at $.22 per
       share. Proceeds to the Company were approximately $997,000. In April
       1998, 5,000,000 shares were issued at $1.25 per share. The proceeds to
       the Company were $6,250,000. In June 1998, 2,000,000 shares were issued
       at $1.75 per share. Proceeds to the Company were approximately
       $3,500,000. The Company incurred approximately $178,014 in offering costs
       relating to these offerings, which have been charged to additional
       paid-in capital.

       In June 1998, the Company offered certain individuals the right to
       acquire common stock at $1.75 per share along with a share purchase
       warrant for every two shares purchased, conditioned upon their acceptance
       of employment as officers of the Company. No compensation cost was
       recorded for the individuals who commenced employment with the Company
       prior to July 1, 1998 (the date the Company's common stock commenced
       trading) as the estimated fair value of common stock approximated the
       common stock issuance price and the warrant exercise price. Compensation

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(5) STOCKHOLDERS' EQUITY (CONTINUED)

       expense of $450,000 was recorded for the shares and warrants issued
       subsequent to July 1, 1998 based on the difference between the closing
       price per share on the last trading day prior to the date of employment
       with the Company and the common stock issuance price and the warrant
       exercise price.

       During the period from inception to December 31, 1998 a total of 796,429
       units were issued at $1.75 per unit to officers and key employees of the
       Company. The units consist of one share of common stock and one warrant
       for each two shares issued. The warrants have an exercise price of $1.75
       per share in the first year and $1.96 per share in the second year and
       are exercisable at any time. Proceeds to the Company were approximately
       $1,394,000.

       In September 1998, the Company issued 980,000 units at $3.25 per unit.
       Each unit consists of one share of common stock and one warrant for each
       two shares issued. The warrants with an exercise price of $5.00 per share
       expire on March 4, 1999. Proceeds to the Company were approximately
       $3,165,000. Offering costs of $324,675 were charged to additional paid in
       capital.

       Under the terms of the stock subscription agreement, one of the
       subscribers to the offering subscribed for an additional 235,000 units.
       An additional $763,750 was deposited into an escrow account representing
       the aggregate purchase price of the additional 235,000 units. Under the
       terms of the escrow agreement the shares and the shares of common stock
       underlying the warrants were to be registered for resale under the
       Securities Act of 1993 (the "Act") with the U.S. Securities and Exchange
       Commission by December 31, 1998. The Company has also undertaken to have
       the shares qualified by way of an exemption order provided by the
       respective Securities Commissions in Canada.

       The escrow proceeds of $763,750 were deposited into an interest bearing
       escrow account together with certificates representing the units to be
       purchased. Under the terms of the subscription agreement, the
       registration statement was required to be declared effective and the
       Canadian exemption order was to be obtained on or before December 31,
       1998. The registration statement has not been declared effective.
       Accordingly as of December 31, 1998, the subscriber may elect to either
       purchase the escrow units or receive a refund from the escrow account
       paid with their subscription, plus interest thereon, and an additional
       unit for each 10 units purchased in the offering. On February 28, 1999
       all the subscribers elected to receive an additional unit for each 10
       units purchased in the offering and, as a result, an additional 121,500
       units are to be issued. The additional units to be issued have been
       reflected in the accompanying financial statements as units to be issued
       from escrow and the $763,750 to be received from escrow has been
       reflected as unit subscriptions receivable. The subscriber is also
       entitled to receive an additional unit for each 10 units previously
       acquired in the offering in the event that the Company does not maintain
       an effective registration statement until such time as the registered
       securities may be resold pursuant to Rule 144 promulgated under the Act.

       time within six months of the date of issuance. The warrants expired
       unexercised on March 4, 1999.

       At December 31, 1998 the Company also has outstanding 398,215 warrants

       years from the date of issuance.

       The Company issued warrants to purchase 128,000 shares of common stock to
       a company for corporate finance services for a period of one year
       commencing April 15, 1998. The warrants are exercisable at $1.25 per
       share anytime after April 15, 1999 and expire April 15, 2000. The
       estimated fair value of the warrants issued of $16,500 was charged to
       expense during the period from January 26, 1998 (inception) to December
       31, 1998. In September 1998, the Company agreed to issue warrants to
       purchase 75,200 shares of common stock to the same company in connection
       with the placement of units in the September 1998 unit offering. The

       warrants are exercisable at $4.72 per share anytime after November 24,
       1998 and expire November 24, 2002. The estimated fair value of the
       warrants issued of $232,202 was capitalized as lease acquisition cost.

    (c) STOCK OPTION AND INCENTIVE PLAN

       On March 24, 1998, the Company adopted the 1998 Stock Option and
       Incentive Plan (the Plan). The aggregate number of shares which may be
       issued as awards under the Plan is 4,500,000 shares. As of December 31,
       1998, options to purchase common stock have been granted to key employees
       and directors at exercise prices ranging from $1.25 to $5.00 per share.

       Stock option activity for the Plan for the period from inception to
       December 31, 1998 is as follows:

       The Company applies APB Opinion 25 and related interpretations in
       accounting for its stock option plans. No compensation expense has been
       recognized for options granted at or above market value at date of grant.
       Compensation expense of $1,340,000 has been recorded for the period from
       inception to December 31, 1998 for options granted below the market
       value, based upon the difference between the option price and the quoted
       market price at the date of grant.

       Had compensation cost for the Company's stock-based compensation plans
       been determined based upon the fair value of options on the grant dates,
       consistent with the provisions of SFAS 123, the Company's pro forma net
       loss and loss per share for the period from January 26, 1998 (inception)
       to December 31, 1998 would have been $6,447,183 and $.57, respectively.

       The weighted average fair value of options granted during 1998 was $1.34
       per share. The weighted average remaining contractual life of all options
       outstanding at December 31, 1998 was approximately 7.1 years. The fair
       value of each option grant was estimated at the date of grant using the
       Black-Scholes option-pricing model with the following assumptions: no
       expected dividends, expected life of the options of 1 to 10 years,
       volatility of 72%, and a risk-free interest rate of 5.5%.

(9) INFORMATION REGARDING PROVED OIL AND GAS RESERVES (UNAUDITED)

        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.

    The table below sets forth the Company's quantities of historical proved
    reserves as estimated by independent petroleum engineers, all of which were
    located in the United States, and the present values attributed to those
    reserves. The estimates were prepared by the independent petroleum
    engineering firm of Ryder Scott Company. Reserve estimates are inherently
    imprecise and are

    The standardized measure of discounted future net cash flows relating to
    proved oil and gas reserves and the changes in standardized measure of
    discounted future net cash flows relating to proved oil and gas reserves
    were prepared in accordance with the provisions of Statement of Financial
    Accounting Standards No. 69. Future cash inflows were computed by applying
    current prices at year-end to estimated future production. Future production
    and development costs are computed by estimating the expenditures to be
    incurred in developing and producing the proved oil and gas reserves at
    year-end, based on year-end costs and assuming continuation of existing
    economic conditions. Future income tax expenses are calculated by applying
    appropriate year-end tax rates to future pretax net cash flows relating to
    proved oil and gas reserves, less the tax basis of properties involved and
    tax credits and loss carryforwards relating to oil and gas producing
    activities. Future net cash flows are discounted at a rate of 10% annually
    to derive the standardized measure of discounted future net cash flows. This
    calculation procedure does not necessarily result in an estimate of the fair
    market value or the present value of the Company's oil and gas properties.

                                 MARCH 31, 1999



                         NOTES TO FINANCIAL STATEMENTS



                                  (UNAUDITED)



(1) ORGANIZATION AND BASIS OF PRESENTATION



    Pennaco Energy, Inc. (the "Company") is an independent exploration and
    production company primarily engaged in the acquisition and development of
    natural gas production from coal bed methane properties in the Rocky
    Mountain region of the United States. The Company was incorporated on
    January 26, 1998 under the laws of the state of Nevada and its headquarters
    are in Denver, Colorado.



    The Company's activities to date have been limited to organizational
    activities, prospect development activities, acquisition of leases and
    option rights, and commencement of its drilling program. The Company
    currently has oil and gas lease rights in the Powder River Basin in
    northeastern Wyoming and southeastern Montana. As of March 31, 1999 the
    Company had no revenue producing operations. Accordingly, the Company is
    considered to be in the development stage.



    The Company was incorporated as a wholly-owned subsidiary of International
    Metal Protection Inc. ("International Metal"). Subsequently, all of the
    outstanding shares of International Metal were exchanged for shares of the
    Company and International Metal was merged into the Company. The 995,000
    shares issued in the exchange were recorded at their par value of $.001 per
    share as International Metal had no assets or liabilities at the date of the
    merger. International Metal and its predecessor, AKA Video Communications
    Inc., had been inactive for the two years ended December 31, 1997 and prior
    thereto.



    In the opinion of management the accompanying financial statements reflect
    all adjustments, consisting of normal recurring adjustments, necessary to
    present fairly the Company's financial position as of March 31, 1999, and
    the results of its operations for the three-month period ended March 31,
    1999 and the period from January 26, 1998 (inception) to March 31, 1998. The
    results of operations for interim periods are not necessarily indicative of
    the results of operations for the full fiscal year. The accounting policies
    followed by the Company are included in Note 1 to the Financial Statements
    in the Company's Annual Report on Form 10-KSB for the period from January
    26, 1998 (inception) to December 31, 1998. These financial statements should
    be read in conjunction with the Form 10-KSB.



(2) OIL AND GAS ACTIVITIES



    The Company follows the successful efforts method of accounting for its oil
    and gas activities. Accordingly, costs associated with the acquisition,
    drilling and equipping of successful exploratory wells are capitalized.
    Geological and geophysical costs, delay and surface rentals and drilling
    costs of unsuccessful exploratory wells are charged to expense as incurred.
    Costs of drilling development wells, both successful and unsuccessful, are
    capitalized. Upon the sale or retirement of oil and gas properties, the cost
    thereof and the accumulated depreciation and depletion are removed from the
    accounts and any gain or loss is credited or charged to operations. Upon the
    sale of a partial interest in an unproved property, the proceeds are treated
    as a recovery of cost. If the proceeds exceed the carrying amount of the
    property, a gain is recognized in operations. Depletion of capitalized
    acquisition, exploration and development costs is computed on the
    units-of-production method by individual fields as the related proved
    reserves are produced.

                                  (UNAUDITED)



(2) OIL AND GAS ACTIVITIES (CONTINUED)


    Capitalized costs of unproved properties are assessed periodically and a
    provision for impairment is recorded, if necessary, through a charge to
    operations.



    Proved oil and gas properties are assessed for impairment on a
    field-by-field basis. If the net capitalized costs of proved oil and gas
    properties exceeds the estimated undiscounted future net cash flows from the
    property a provision for impairment is recorded to reduce the carrying value
    of the property to its estimated fair value.



(3) CMS TRANSACTION



    On October 23, 1998, the Company and CMS Oil and Gas Company signed a
    definitive agreement (the "CMS Agreement") relating to the development of
    the Company's Powder River Basin acreage (the "CMS Transaction"). Pursuant
    to the terms of the CMS Agreement, CMS Oil and Gas Company acquired an
    undivided 50% working interest in approximately 492,000 net acres of
    Pennaco's leasehold position in the Powder River Basin for $28,000,000. The
    Company acquired the leasehold position which was conveyed to CMS in the CMS
    Transaction for approximately $7,000,000. The purchase price provided for in
    the CMS Agreement was the result of arm's length negotiations between the
    Company and CMS. The joint operating agreement between the parties will be
    modeled after the 1989 AAPL Model Form of Joint Operating Agreement. The CMS
    Agreement provides that the parties will in good faith negotiate a
    development agreement for the exploration, development and production of
    coal bed methane from the leases. The development agreement will provide
    that each party will operate approximately 50% of the wells drilled in the
    area of mutual interest. Pennaco and CMS have divided the acreage in the
    area of mutual interest into project areas which will be operated by one
    party or the other. As is customary in oil and gas leasehold transactions,
    the agreement provides for the adjustment of the purchase price for title
    defects discovered prior to closing and for the opportunity for one party to
    participate in acquisitions made by the other party in the area of mutual
    interest defined in the agreement. The agreement also provides for a
    preferential purchase right to the other party in the event either CMS or
    the Company attempts to sell a portion of its interest in the acreage
    covered by the agreement. There is no preferential purchase right in the
    event that either party enters into a merger, reorganization or
    consolidation. All of the leases in the area of mutual interest are
    dedicated to CMS Gas Transmission and Storage, an affiliate of CMS Oil and
    Gas Company, for gathering, compression and transportation. Pursuant to the
    terms of the CMS Agreement, CMS agreed to pay Pennaco $5,600,000 of earnest
    money in the form of a non-interest bearing bridge loan (the "CMS Bridge
    Loan") which was secured by substantially all of the Company's oil and as
    leases. Approximately $3,200,000 of such amount was paid directly to
    existing creditors of the Company. The CMS Transaction was structured such
    that the conveyance of the working interests was to occur at two separate
    closings. The first closing occurred on November 20, 1998, and the second
    occurred on January 15, 1999. The Company received $7,600,000 at the first
    closing and received $14,800,000 at the second closing, less approximately
    $1,800,000 which was held in escrow subject to customary closing
    adjustments. As of March 31, 1999, approximately $1,200,000 was held in
    escrow pending CMS closing adjustments. The CMS Bridge Loan was canceled at
    the second closing. Under the terms of the CMS Agreement, CMS will pay the
    Company for its share of

    the costs of acquiring any acreage in excess of the original 492,000 net
    acres. The joint venture acreage in the area of mutual interest is
    approximately 560,000 net acres as of January 15, 1999.



    In the accompanying financial statements, the proceeds are treated as a
    recovery of cost of the properties. A gain was recognized to the extent the
    proceeds exceeded the carrying amount of the properties.



(4) STOCKHOLDERS' EQUITY



    In September 1998, the Company issued 980,000 units at $3.25 per unit. Each
    unit consists of one share of common stock and one warrant for each two
    shares issued. The warrants with an exercise price of $5.00 per share expire
    on March 4, 1999. Proceeds to the Company were approximately $3,165,000.
    Offering costs of $324,675 were charged to additional paid-in capital.



    Under the terms of the Company's September 1998 stock subscription
    agreement, 235,000 units were placed in an escrow account. Subscription
    payments of $763,750 were deposited into an escrow account representing the
    aggregate purchase price of 235,000 units. Under the terms of the escrow
    agreement the shares and the shares of common stock underlying the warrants
    were to be registered for resale under the Securities Act of 1933 (the
    "Act") with the Securities and Exchange Commission by December 31, 1998. The
    Company has also undertaken to have the shares qualified by way of an
    exemption order provided by the respective Securities Commissions in Canada.



    The escrow proceeds of $763,750 were deposited into an interest bearing
    escrow account together with certificates representing the units to be
    purchased. Under the terms of the subscription agreement, the registration
    statement was required to be declared effective and the Canadian exemption
    order was to be obtained on or before December 31, 1998. The registration
    statement was not declared effective by this date. Accordingly, as of
    December 31, 1998, the subscriber was entitled to elect to either purchase
    the escrow units or receive a refund from the escrow account paid with their
    subscription plus interest thereon, and an additional unit for each 10 units
    purchased in the offering. On February 28, 1999, virtually all of the
    subscribers elected to purchase the escrow shares and all subscribers
    received an additional unit for each 10 units purchased in the offering. As
    a result, an additional 120,250 units were issued. These 120,250 units have
    been reflected in the accompanying financial statements as an addition to
    paid-in capital and as a reduction to retained earnings. Additionally,
    222,500 units were issued from escrow and proceeds of $723,125 were received
    by the Company from escrow. One subscriber elected not to purchase escrow
    shares and instead received a refund from escrow of $40,625 which
    represented 12,500 units, which were in turn not issued.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The Nevada Revised Statutes and certain provisions of the Company's Bylaws
under certain circumstances provide for indemnification of the Company's
officers, directors and controlling persons against liabilities that they may
incur in such capacities. A summary of the circumstances in which such
indemnification is provided for is contained herein, but this description is
qualified in its entirety by reference to the Company's Bylaws and to the
statutory provisions.

    In general, any officer, director, employee or agent may be indemnified
against expenses, fines, settlements or judgments arising in connection with a
legal proceeding to which such person is a party, if that person's actions were
in good faith, were believed to be in the Company's best interest, and were not
unlawful. Unless such person is successful upon the merits in such an action,
indemnification may be awarded only after a determination by independent
decision of the Board of Directors, by legal counsel, or by a vote of the
stockholders, that the applicable standard of conduct was met by the person to
be indemnified.

    The circumstances under which indemnification is granted in connection with
an action brought on behalf of the Company is generally the same as those set
forth above; however, with respect to such actions, indemnification is granted
only with respect to expenses actually incurred in connection with the defense
or settlement of the action. In such actions, the person to be indemnified must
have acted in good faith and in a manner believed to have been in the Company's
best interest, and must not have been adjudged liable for negligence or
misconduct.

    Indemnification may also be granted pursuant to the terms of agreements that
may be entered in the future or pursuant to a vote of stockholders or directors.
The statutory provision cited above also grants the power to the Company to
purchase and maintain insurance which protects its officers and directors
against any liabilities incurred in connection with their service in such a

Securities Act.

    (a) The Company issued 995,000 shares in January 1998 pursuant to a
share-for-share exchange with the stockholders of International Metal
Protection, Inc. in a transaction conducted solely to reincorporate the Company
in a new jurisdiction. This transaction was exempt from the registration
requirements of the

                                      II-1
<PAGE>
Securities Act pursuant to Section 4(2) of the Securities Act. There was no
change in ownership and the stockholders made no significant investment
decision.


    (b) The Company issued 500,000 shares in February 1998 for the purchase
price of $.10 per share pursuant to a private placement exempt from the
registration requirements of the Securities Act pursuant to Section 4(2) of the
Securities Act. At that time, the Company had only a business plan and no
assets. There were eleven offerees in this offering, all of whom made purchases
and all of whom were sophisticated investors. The Company fully apprised each of
the offerees of the Company's start-up nature and gave them full details
regarding the Company's business plan. There was no general solicitation or
advertising used in connection with the offer to sell or sale of these
securities. The purchasers were advised that the securities, once purchased,
could not be resold or otherwise transferred without subsequent registration
under the Securities Act. Each purchaser represented to the Company that they
were purchasing the securities for their own account for investment purposes
only.


    (c) The Company issued 4,530,000 shares in February 1998 for a purchase
price of $.22 per share pursuant to a Regulation D, Rule 504 offering. Offerees
were provided with a private placement memorandum containing detailed
information about the Company and its plan. The Company required each
prospective investor to represent in writing that (i) they had adequate means of
providing for their current needs and personal contingencies and had no need to
sell the securities in the foreseeable future and (ii) they, either alone or
with their duly designated purchaser representative, had such knowledge and
experience in business and financial matters that they were capable of
evaluating the risks and merits of an investment in the securities.

    (d) The Company issued 5,000,000 shares in April 1998 for a purchase price
of $1.25 per share pursuant to a Regulation D, Rule 506 offering. The Company
accepted subscriptions only from accredited investors. Offerees were provided

Company and its plan. The Company required each prospective investor to
represent in writing that (i) they had received and reviewed the private
placement memorandum and understood the risks of an investment in the Company;
(ii) they had the experience and knowledge with respect to similar investments
which enabled them to evaluate the merits and risks of such investment, or they
had obtained and relied upon an experienced independent adviser with respect to
such evaluation; (iii) they had adequate means to bear the economic risk of such
investment, including the loss of the entire investment; (iv) they had adequate
means to provide for their current needs and possible personal contingencies;
(v) they had no need for liquidity of their investment in the Company; (vi) they
understood that the securities had not been registered under the Securities Act

laws and, therefore, that they could not sell or transfer the securities unless
the securities were subsequently registered or an exemption therefrom was
available to them; (vii) they were acquiring the securities for investment
solely for their own account and without any intention of reselling or
distributing them; and (viii) they understood that the securities would bear a
restrictive legend prohibiting transfers except in compliance with the

purchaser and the applicable federal and state securities laws.

services to the Company for one year in return for these warrants.

ITEM 28.  UNDERTAKINGS.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

    The undersigned registrant hereby undertakes:

    (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement: (i) to include any
prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to
reflect in the prospectus any facts or events arising after the effective date
of the registration statement (or the most recent post-effective amendment
thereof) which, individually or in the aggregate, represent a fundamental change
in the information set forth in the registration statement. Notwithstanding the
foregoing, any increase or decrease in volume of securities offered (if the
total dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated maximum
offering range may be reflected in the form of prospectus filed with the
Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume
and price represent no more than a 20% change in the maximum aggregate offering
price set forth in the "Calculation of Registration Fee" table in the effective
registration statement; and (iii) to include any additional or changed material
information on the plan of distribution.

    (2)  that, for purposes of determining any liability under the Securities
Act of 1933, the information omitted from the form of prospectus filed as part
of this registration statement in reliance upon Rule 430A and contained in a
form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.


    (3)  that, for the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereto.

                             GAS GATHERING AGREEMENT


         This Gas Gathering Agreement ("Agreement") is entered into and
effective as of this 1st day of February, 1999, ("the Effective Date"), by and
between PENNACO ENERGY, INC., a Nevada corporation ("Producer"), and BEAR PAW
ENERGY INC., a Colorado corporation, ("Gatherer").

                                    RECITALS

         A.   Producer owns, controls or is agent for an undivided interest in
certain oil and gas leases, coal bed methane leases and agreements, wells and/or
lands which produce natural gas/methane from coal seams in Campbell County,
Wyoming, as set forth on Exhibit B attached hereto and incorporated herein by
reference (the "Subject Lands"), and wishes to drill natural gas wells to
further develop its coalbed methane gas reserves.

         B.   Producer desires to produce and deliver Gas from the Subject Lands
to Gatherer and Gatherer desires to receive and gather from Producer said Gas,
all on the terms and conditions set forth herein.

         NOW THEREFORE, in consideration of the above recitals and the mutual
promises, covenants, commitments, and agreements herein contained, Producer and
Gatherer agree as follows:

                                    ARTICLE I
                           DEFINITIONS AND DEDICATION

         A.   The definitions specified in the Appendix to this Agreement set
forth as Exhibit A (the "Appendix") are incorporated herein by reference, unless
the context of this Agreement shall require otherwise. In the event of any
conflict between the terms as set out in the body of this Agreement and those
set out in the Appendix, the terms in the body of this Agreement shall control.
The terms defined within this Agreement are, as follows:

            "APPENDIX" shall have the meaning set forth in Article I.A.

            "CONNECT" shall have the meaning set forth in Article II.F.

            "DUE DATE" shall have the meaning set forth in Article VI.B.

            "EFFECTIVE DATE" shall have the meaning set forth above.

            "GISB" shall have the meaning, as set forth in Article V.A.

<PAGE>


            "INITIAL FACILITIES" shall have the meaning as set forth in
            Article IV.B. I

            "MASTER METER" shall have the meaning as set forth in Article II.F.

            "POINTS OF DELIVERY" shall have the meaning set forth in
            Article 2.A of the Appendix.

            "REDELIVERY POINTS" shall have the meaning set forth in Exhibit E.

            "SUBJECT LANDS" shall have the meaning set forth in Recital A.

            "WELLHEAD METERING FACILITY" shall have the meaning set forth in
            Article II.F.

         B.   Subject to the terms and conditions of this Agreement, Producer
hereby commits and dedicates to the performance of this Agreement all of its
interest in the Subject Lands, without limitation, as set forth on Exhibit B
hereto and all of Producer's Gas reserves thereunder, for the life of the
production from the Subject Lands, together with any extensions, renewals or
modifications of the Subject Lands, whether now owned or hereafter acquired
during the term of this Agreement.

         C.   The Parties hereto agree to establish an Area of Mutual Interest
("AMI") as depicted on Exhibit C, attached hereto and incorporated herein by
reference. Producer agrees to dedicate to Gatherer, under the terms contained in
this Agreement, all interest currently owned or subsequently acquired by
Producer in lands and/or leases in the AMI whether or not they are described on
Exhibit B hereto. Gatherer agrees to receive and gather all of Producer's Gas
produced from the AMI subject to the terms and conditions set forth in this
Agreement.

         D.   Gatherer shall gather Producer's Gas from the Point(s) of Delivery
and shall redeliver thermally equivalent volumes at the Redelivery Points, less
Fuel, water, and Pipeline Loss as provided in this Agreement. Gatherer shall
have the right but not the obligation to commingle Gas delivered hereunder with
Gas gathered by Gatherer for other producers provided that Producer's Gas is
gathered on a priority basis. However, in the event capacity on a downstream
pipeline is restricted, Producer's Gas will be redelivered as dictated by the
downstream pipeline.

                                   ARTICLE II
                    CONSTRUCTION OF PIPELINE GATHERING SYSTEM

         A.   Gatherer agrees to complete the construction of and equip and
operate sufficient miles of pipeline gathering facilities to connect all of the
wells drilled and produced, or to be drilled and produced, on the Subject Lands
by Producer at the Point(s) of Delivery described on Exhibit D. The original
design of the pipeline gathering facilities to be completed by Gatherer is
intended to be as follows:

           Anticipated production of 250 Mcf/d per well
           Nineteen (19) wells from the Swanson Acreage x 250 mcfd = 4,750 mcfd

                                       2

<PAGE>

           Seventeen (17) wells from the Jim Wolff Acreage x 250 mcfd = 4,250
              mcfd
           Twenty (20) wells from the Harry Wolff Acreage x 250 mcfd =
              5,000 mcfd
           Twenty-eight (28) wells from the Hemela Acreage x 250 mcfd = 7,000
              mcfd
           Twenty-two (22) wells from the Rourke Acreage x 250 mcfd = 5,500
              mcfd
           Compression facilities downstream of the Wellhead Metering
              Facilities to maintain a suction pressure between 0 to 2 psig
           4" SDRI 7 poly pipe from wellhead to Wellhead Metering Facilities

         B.   Gatherer shall have the option to make connections on Gatherer's
Facilities for new Gas developed and produced and saved by Producer on the
Subject Lands described on Exhibit B. If such proposal is to gather such Gas
under the terms and conditions set forth in this Agreement, including, but not
limited to, the design specifications in Article ILA and the service rates and
charges as set forth in Article IV, then such proposal shall be deemed accepted
by Producer. Otherwise, throughout the term of this Agreement, within fifteen
(15) Days from receipt of notice of the completion of sufficient deliverable
quantities of Gas by Producer on the Subject Lands listed on Exhibit B, Gatherer
shall submit a written proposal to Producer to construct and install the
necessary facilities to gather said Gas. Producer shall have 30 Days from
receipt of such proposal to accept or reject Gatherer's proposal for gathering
service hereunder. Failure to respond within the said 30 Day-time period shall
be deemed an election by Producer to reject said proposal.

         C.   Upon receipt of written acceptance of said proposal by Producer or
if such proposal is deemed accepted as provided in Article II.B above, Gatherer
shall commence in a commercially reasonable manner construction and installation
of the gathering facilities necessary to gather Producer's Gas and redeliver
said Gas to the Redelivery Point(s) set forth on Exhibit E, as may be amended
from time to time.

         D.   Should Producer decline the proposal as set forth above, Gatherer
shall not be obligated to make any such connection, and Producer may require
Gatherer to release such well(s) from the Agreement, but only as to the
formation in which such well was originally completed at the time Gatherer
determined the connection to be uneconomic.

         E.   Except for the wells to be connected to the Initial Facilities, in
the event Producer desires Gatherer to connect a group or pod of wells to
Gatherer's Facilities which wells, in Gatherer's sole opinion, would not
constitute an economic connection, Gatherer shall be under no obligation to
connect any such wells, or to accept any Gas therefrom. In the event Gatherer
deems the connection of a group of wells to be uneconomic such that Gatherer
declines to connect such wells, Producer may construct its own field system
connecting such wells and may thereafter connect such facilities to Gatherer's
Facilities. In recognition of the fact that the services required by Gatherer
shall be reduced as a result of Producer's connection, Gatherer's fees for the
services to be provided by Gatherer to complete the gathering of such Gas shall
be appropriately reduced.. In setting these fees, the Parties shall take into
consideration the breakdown of fees set forth in Article IV.

                                       3

<PAGE>


         F.   The term "connect" as used in this Agreement means that
Gatherer shall take custody of Producer's Gas at the Point(s) of Delivery of
each well to be connected to Gatherer's Facilities and shall install such
facilities as are necessary to gather the Gas produced from each such well to
a Wellhead Metering Facility ("WMF") at which the Gas from each well shall be
metered, and from each WMF to the Redelivery Points specified on Exhibit E.
Downstream of each WMF, Gatherer shall install an electronic flow meter to be
used for payment, nominations and imbalance calculations under this Agreement
("Master Meter").

                                   ARTICLE III
                          QUANTITY AND DELIVERY OF GAS

         A.   The Parties agree that certain acreage as described on Exhibit
C is dedicated for redelivery to Western Gas Resources, Inc. ("WGR") under
separate agreement. Gatherer agrees to gather up to 11.0 MMcfd from the WGR
acreage dedication and redeliver said Gas to the interconnect with WGR as
described on Exhibit E. All Gas in excess of 11.0 MMcfd gathered from the WGR
acreage dedication may be gathered and redelivered to any of the proposed
Redelivery Points as described on Exhibit E or any redelivery points that may
be added to Exhibit E from time to time as mutually selected by the Parties
if such Gas is released from dedication by WGR. Gas from the remaining
Subject Lands may be gathered and delivered to any of the proposed redelivery
points as mutually selected by the Parties.

         B.   Producer represents that the Gas to be gathered and redelivered
shall be delivered to Gatherer in conformance with the specifications and
conditions set forth in the Appendix, including Gatherer's Gas quality
specifications.

                                   ARTICLE IV
                            SERVICE RATES AND CHARGES

         A.   Gatherer shall gather and redeliver Producer's Gas and Producer
agrees to pay a gathering fee for redelivery to the interconnect with WGR as
described on Exhibit E. The total gathering fee shall be ******** per Mcf as
measured at each Master Meter until such time as additional redelivery points
other than WGR are available. This gathering fee is comprised of: (i) a fee of
******** per Mcf for gathering service from the wellheads to and through the WMF
as measured at the Master Meter; and (ii) a fee of ******** per Mcf for service
from the WMF to the WGR Redelivery Point as described on Exhibit E as measured
at the Master Meter.

         1.   Upon completion of an interconnect with a proposed redelivery
point described on Exhibit E, Producer agrees to pay a total gathering fee of
******** per Mcf as measured at each Master Meter other than the WGR acreage
dedication Points of Delivery which shall continue to be charged the********
gathering fee. This gathering fee is comprised of: (i) a fee of ******** per
Mcf for service from the wellheads to and through the WMF as measured at the
Master Meter; and (ii) a fee of ******** per Mcf for service from the WMF to
the proposed Redelivery Points as described on Exhibit E as measured at the
Master Meter.

                                       4

<PAGE>

         2.   For any WGR acreage dedication Gas in excess of 11.0 MMcfd
requiring additional capital expenditure by Gatherer, the Parties shall
negotiate a mutually agreeable gathering fee.

         3.   For Gas in excess of 11.0 MMcfd that is released from
dedication by WGR and redelivered to any of the proposed Redelivery Points,
Producer agrees to pay a total gathering fee of ******** per Mcf as set forth
above.

         B.   After completion of the Initial Facilities, the total Monthly
gathering fee paid by Producer shall not be less than ******** for the first
Accounting Period, not less than ******** for the second Accounting Period and
not less than ******** for the next fifty-eight (58) Accounting Periods
("Minimum Payments") regardless of the volumes actually delivered to Gatherer.
Should the product of the. actual Monthly volumes as measured at the Master
Meter(s) multiplied by the appropriate gathering fees as set forth in Paragraph
A of this Article IV be less than the Minimum Payment, Gatherer shall invoice
Producer for the remaining balance, payment of which shall be due as provided in
Article VI. Should the product of the actual Monthly volumes as measured at the
Master Meter(s) multiplied by the appropriate gathering fees as set forth in
Paragraph A above be more than the Minimum Payment, Gatherer shall invoice
Producer for the actual Mcf's delivered multiplied by the appropriate gathering
fee set forth in Paragraph A above, payment of which shall be due as provided in
Article VI. The Minimum Payment shall be subject to reduction in the event
Gatherer refuses to accept Gas tendered from Producer which otherwise meets the
specifications of this Agreement, or in the event of a force majeure affecting
Gatherer's facilities which impairs Gatherer's ability to accept Producer's Gas.
No Minimum Payment shall apply during any such Month during which Gatherer's
refusal to accept Gas tendered or Gatherer's force majeure is the cause of
Producer's failure to meet the Minimum Payment.

         1 .   "Initial Facilities" shall be the facilities necessary for
Gatherer to gather Gas produced from the Points of Delivery in the Swanson,
Jim Wolff (should Producer finalize the purchase of such acreage), Harry
Wolff, Hemela and Rourke acreage as described on Exhibit D and redeliver said
Gas to the interconnect with WGR as described on Exhibit E. Gatherer shall
use commercially reasonable efforts to complete the Initial Facilities on or
before April 1, 1999.

         C.   In addition to the foregoing, and not in limitation thereof,
the following additional fees and charges shall be applicable:

              1.   Producer shall reimburse Gatherer for the actual tap fee,
         measurement costs and any associated costs relating to the interconnect
         between Gatherer's Facilities and the Redelivery Point(s). Said
         reimbursement shall be based on Producer's maximum volume requirements
         at each interconnect as provided to Gatherer by Producer in writing.
         Gatherer shall use reasonable efforts to minimize all costs associated
         with said interconnects.

              2.   An alternative power/fuel source fee, in the event any of
         Producer's Gas flows through a compression facility or facilities
         powered by electrical power, or any fuel or power source other than Gas
         being delivered into Gatherer's Facilities, equal to Producer's
         allocable

                                       5

<PAGE>

         portion of the power or alternative fuel costs necessary to operate
         such facility or facilities. Such costs shall be allocated to each
         Point of Delivery by multiplying the total power and fuel cost of each
         compression facility for an Accounting Period by a fraction, the
         numerator of which shall be the volume of Gas flowing through the
         facility attributable to the particular Point(s) of Delivery and the
         denominator of which shall be the total volume of Gas flowing through
         such facilities. Gatherer shall charge Producer, on a Monthly basis,
         the resultant product.

              3.   If treating of the Gas is required, Producer and Gatherer
         shall negotiate a mutually agreeable treating fee.

              4.   Beginning April 1, 2004, the fees described in Paragraph A
         of this Article IV shall be escalated pursuant to changes reflected by
         the Producer Price Index, using as a base such Index as it exists on
         January 1, 2004 as the basis for such adjustment. Escalation of the
         fees set forth in Paragraph A above shall occur annually (on January 1
         of each year) pursuant to adjustments reflected in the Producer Price
         Index. In the event the Producer Price Index is discontinued or
         modified, an index most similar to the Producer Price Index shall
         thereafter be used. However, in no event shall the ******** fee
         described in Paragraph A of this Article IV be greater than ********
         per Mcf and the ******** fee described in Paragraph A above be greater
         than ******** per Mcf.

                                    ARTICLE V
                         NOMINATIONS AND DELIVERY TERMS

         A.   Gas to be delivered by Producer shall be nominated upon terms and
conditions to be agreed upon by the Parties consistent with the requirements of
downstream pipelines. Nominations shall be submitted in writing via facsimile
using the Nomination form attached hereto as the "Nomination Schedule". Producer
shall submit the total volume to be nominated from all Point(s) of Delivery at
least five (5) working Days prior to the first Day of each Month. Unless
required earlier to allow the Parties to meet downstream nomination
requirements, nominations of specified volumes to downstream pipeline(s) shall
be submitted at least one (1) Day prior to the nomination deadline of the
downstream pipeline(s) pursuant to Gas Industry Standards Board ("GISB")
standards. Producer shall give at least twenty-four (24) hours notice of
nomination changes. Producer's nominations shall be confirmed or rejected within
twenty-four (24) hours of receipts Nominations shall not be rejected without
cause. Producer shall use its best efforts to maintain uniform hourly rates of
delivery at all Points of Delivery hereunder to the extent practicable. Gas
shall be measured at the Master Meters and shall meet the specifications as set
forth on the Appendix or as provided by the downstream pipeline.

         B.   To aid Producer in preparation of its Nominations, Gatherer shall
from time to time as Producer may reasonably request, provide Producer with its
best, good faith estimate of the amount of Pipeline Loss and Fuel Gas
anticipated to occur from the Points of Delivery to the Redelivery Point(s).

                                       6

<PAGE>

         C.   In addition to its nominations for deliveries to Gatherer at
the Point(s) of Delivery, Producer shall also submit to Gatherer nominations
for delivery to the Redelivery Point(s) as set forth on the Nomination
Schedule based upon Gatherer's estimate of Fuel Gas and Pipeline Loss. Such
nominations at the Redelivery Point(s) shall be consistent with those issued
by Producer to. each pipeline company accepting Producer's Gas at each
respective Redelivery Point. Recognizing that operating conditions may from
time to time result in actual deliveries by Producer at the Point(s) of
Delivery or the Redelivery Point(s) in amounts greater or less than those so
nominated, the following procedures, rights and obligations shall apply:

              1.   Gatherer shall attempt to verify that the amounts nominated
         by Producer to Gatherer hereunder as reflected on the Nomination
         Schedule and nominated to the pipeline company accepting Producer's Gas
         at the Redelivery Point(s) are consistent. Producer and Gatherer shall
         communicate and cooperate to insure that any discrepancy in those
         nominations shall be promptly reported to each other and the pipeline
         company accepting Producer's Gas at the Redelivery Point(s).

              2.   Gatherer shall operate its Facilities in order to accept and
         redeliver Gas hereunder in such a way as to maintain balance on its
         Facilities as between receipts and redeliveries of Gas subject to the
         Agreement as closely as possible. Gatherer shall have the right to
         refuse to accept volumes if Producer's deliveries exceed its
         nominations, or to refuse to confirm nominations if nominations exceed
         deliveries. Nothing herein shall be construed to require Gatherer to
         deliver Gas to any Redelivery Point(s) in excess of that actually
         received by Gatherer from Producer at the applicable Point(s) of
         Delivery.

              3.   Gatherer shall include in its Monthly statement of Producer's
         metered volumes at each WMF, Producer's allocated share of the Gas
         metered at each Master Meter, Fuel Gas, Pipeline Loss on Gatherer's
         Facilities, and the Gas allocated to Producer at each Redelivery Point.
         The difference between the sum of Producer's allocated share of Gas
         metered at each Master Meter and the sum of the Gas allocated to
         Producer at each Redelivery Point, less Pipeline Loss and Fuel Gas
         shall constitute Producer's imbalance on Gatherer's Facilities. The
         Parties shall endeavor to balance Thermally Equivalent volumes of Gas
         received and redelivered for Producer as nearly as feasible. Gatherer
         and Producer shall cooperate to eliminate any cumulative imbalance as
         soon as is practicable after the Monthly accounting of the cumulative
         imbalance. If Gatherer has received less Gas than it has credited to
         Producer at the Redelivery Points, then Producer shall increase
         deliveries to Gatherer or decrease nominations in order to eliminate
         such imbalances. If Gatherer has received more Gas than has been
         credited to Producer at the Redelivery Points, then Producer shall
         decrease deliveries to Gatherer or nominate increased volumes in order
         to eliminate such imbalance.

              4.   In recognition that Gas gathered under this Agreement is
         purchased from, sold to, or transported by third parties, Producer and
         Gatherer shall use reasonable efforts to cause each such third party to
         cooperate fully with the Parties' efforts to maintain balance on
         Gatherer's Facilities.

                                       7

<PAGE>

              5.    If deemed necessary by the Parties, Gatherer shall use
         reasonable efforts to enter into Operational Balancing Agreements with
         downstream transporters at such Redelivery Point(s) so that Producer
         may be credited at such Redelivery Point(s) with its confirmed
         nominations for such point. Additionally, Gatherer represents that all
         producers who are or may be connected to the Gatherer's Facilities are
         or will, upon connection, be subject to provisions similar to those in
         subparagraphs 1 through 4 above. Gatherer agrees to enforce such
         provisions on a nondiscriminatory basis so as to minimize imbalances on
         Gatherer's Facilities and the risk of downstream imbalances for all
         parties whose gas is gathered by Gatherer.

              6.   Gatherer shall keep accurate records of the quantities of
         Gas nominated and scheduled for gathering and any imbalances, which
         records shall be reported to Producer on a Monthly basis. If Producer's
         Gas is commingled with other gas at the Point(s) of Delivery, the
         wellhead operator shall provide Gatherer with the allocation of the Gas
         at such Point. If Producer's Gas is commingled with other gas at the
         Redelivery Point(s), Gatherer shall provide the operator of the
         downstream facilities at such Redelivery Point(s) with the allocation
         of such Gas. Such allocation shall be based upon the methodology set
         forth in Section 8 of the Appendix.

              7.   Gatherer and Producer recognize that the primary obligation
         and burden of responsibility to monitor, control, adjust and maintain a
         concurrent balance between nominations and deliveries of Gas shall rest
         with Producer. Therefore, except to the extent otherwise set forth
         above, Gatherer does not assume, by the provisions of this section, the
         responsibility or obligation to monitor or adjust Producer's
         nominations or deliveries.

              8.   Except as provided in subparagraph 9 below, Gatherer shall
         not be liable for any penalties and charaes incurred by Producer with
         any downstream pipeline to which Gatherer is delivering Producer's Gas.
         Producer agrees to indemnify and hold harmless Gatherer, its parents,
         members, subsidiaries and affiliate corporations or entities, and their
         respective officers, directors, employees, members and agents, and
         co-venturers (if any) in the performance of this Agreement, from and
         against any and all claims, causes of action, penalties, liabilities,
         damages and losses pertaining to such penalties and charges.

              9.   All penalties and charges incurred by Producer with any
         downstream pipeline to which Gatherer is delivering Producer's Gas by
         reason of Gatherers failure to deliver Producer's nominated volumes
         which were properly delivered to Gatherer by Producer shall be the sole
         responsibility of Gatherer. Gatherer agrees to indemnify and hold
         harmless Producer, its parents, members, subsidiaries and affiliate
         corporations or entities, and their respective officers, directors,
         employees, members and agents, and co-venturers (if any) in the
         performance of this Agreement, from and against any and all claims,
         causes of action, penalties, liabilities, damages and losses pertaining
         to such penalties and charges.

<PAGE>



                             STATEMENTS AND PAYMENTS

         A.   On or before the fifteenth (15th) Day of each Accounting Period,
Gatherer shall send to Producer a statement of charges for Gas gathering and
other services rendered hereunder in the previous Accounting Period along with
any Minimum Payment due Gatherer under this Agreement.

         B.   Producer shall pay Gatherer by Electronic Funds Transfer to a
designated bank account established by Gatherer. Payments shall be made by
Producer to Gatherer within ten (10) Days from the date on which the statement
is received ("Due Date") for all charges billed. Payments made by Electronic
Funds Transfer shall be considered to have been made on the date when such
payment of good funds is received by Gatherer. To avoid uncertainty respecting
date of receipt of statements, Gatherer may fax its statement and the fax
confirmation date shall be deemed the date of receipt.

         C.   Should Producer fail to pay part or all of the amount of any such
statement, interest thereon shall accrue on the unpaid balance at the prime rate
per annum. plus two percent (2%) compounded on a quarterly basis. For purpose
hereof, the prime rate shall be that rate established by BankBoston N.A. as the
most favorable rate available to business customers, such rate to change upon
each announced rate change; provided, that the interest rate to be applied to
unpaid balances hereunder shall not exceed the maximum rate permitted under
Colorado law. If such failure to pay continues thirty (30) Days after payment is
due, Gatherer, in addition to any other remedy it may have may suspend further
service to Producer until such amount is paid after Gatherer provides Producer
with ten (10) Days prior written notice; provided, however, that if Producer in
good faith disputes in writing the amount of any such statement or parts thereof
and pays to Gatherer such amounts as it concedes to be correct, and at any time
thereafter within thirty (30) Days of demand made by Gatherer shall furnish a
good and sufficient surety bond guaranteeing payment to Gatherer of the amount
ultimately found due upon such statements after a final determination, which may
be reached either by Agreement or judgment of the courts as may be the case,
then Gatherer shall not be entitled to suspend service on account of failure to
pay such charges unless and until default be made in the conditions of such
bond. If resolution of the dispute is in favor of Producer and Producer
furnished a surety bond instead of paying the disputed amount, then Gatherer
shall reimburse Producer for the cost of securing that surety bond. No payment
by Producer of the amount of a disputed bill shall prejudice the night of either
Party to claim an adjustment of the disputed statement.

         D.   In the event that an error is discovered in the amount billed or
paid hereunder, such error shall be adjusted within thirty (30) Days of the
determination thereof, provided that claim therefor shall have been made within
twenty-four (24) Months from the date of the applicable billing.

         E.   Each Party shall preserve for a period of at least two (2)
years on a rolling basis all test data, charts, and other similar records
relating to each Accounting Period for audit purposes. After twenty-four (24)
Months, all data, charts, and other similar records pertaining to a
particular Accounting Period shall be presumed to be correct, unless written
notice of contest is presented to Gatherer within said time period.

         F.   Either Party, upon thirty (30) Days prior written notice and upon
execution of a confidentiality agreement, a form of which is attached hereto as
Exhibit F, shall have the right, at reasonable times during business hours, but
no more frequently than once each calendar year, at its expense, to examine the
books and records of the other Party to the extent necessary to audit and verify
the accuracy of any statement, charge, or computation made under or pursuant to
this Agreement. The scope of such audit shall be limited to the twenty-four (24)
Month period prior to the Month in which such audit commences. All statements,
allocations, measurements, and payments made in any period prior to the
twenty-four (24) Months preceding such Month shall be conclusively deemed true
and correct. The Party conducting the audit shall have six (6) Months after
commencement of the audit in which to submit a written claim, with supporting
detail, for adjustments.

<PAGE>

                                      TERM

         A.   This Agreement shall be in full force and effect as of the
Effective Date and shall continue and remain in full force and effect
thereafter for the life of production from the Subject Lands.

                                    ARTICLE IX
                                SPECIAL PROVISIONS

         A.   The Parties acknowledge that maximum online performance of
Gatherer's Facilities is important to Producer's ability to maximize production
from the Subjects Lands. In recognition thereof, Gatherer agrees to an online
performance of Gatherer's Facilities of ninetyeight percent (98%) of the hours
in each Month for which Producer delivers volumes of Gas to Gatherer in
quantity, quality and at a pressure which do not prevent Gatherer from
performing its responsibilities under the terms of this Agreement.

              One hundred percent (100%) online performance for a single
              compressor is considered to be seven hundred thirty (730)
              hours per Month. The online performance of Gatherer's
              Facilities shall be calculated by multiplying a fraction, the
              numerator of which is the aggregate runtime hours of all
              compressors on Gatherer's Facilities plus aggregate downtime
              hours for reasons listed in subparagraph A.1 of this Article
              IX and the denominator of which is the number of compressors
              multiplied by seven hundred thirty (730) hours, by one hundred
              (100) (conversion to percent).

              EXAMPLE OF ONLINE PERFORMANCE PERCENTAGE CALCULATION:

         (AGGREGATE RUNTIME HRS + EXCLUDED AGGREGATE DOWNTIME HRS) x 100
                  = Percent Runtime Number of Units x 730 hours

         1.   Online performance will be calculated EXCLUDING the following:

                  -    Conditions of force majeure as defined in Section 11 of
                       the Appendix;
                  -    Conditions in Producers facilities at the Leases having
                       the effect of substantially reducing the volumes of Gas
                       delivered to Gatherer, or having the direct effect of
                       disrupting the operations of Gatherer;
                  -    Shutdown of Gatherer's Facilities for routine maintenance
                       (not to exceed four (4) hours per Month per unit) or
                       overhaul maintenance (not to exceed two (2) Days per
                       calendar year per unit), any other prudent and necessary
                       operation reason or for modification, expansion or
                       replacement.

              Gatherer shall reduce Producer's gathering fee by two-tenths of
              one cent ($.002) for every one percent (1%) of online performance
              below ninety-eight percent (98%). The

              reduction in fees shall be calculated down to an online
              performance of ninety percent (90%).

         B.   If Gatherer is unable to maintain online performance of ninety
percent (90%) as described in Paragraph A of this Article IX for any three
(3) Months within a six (6) Month period, Producer may provide written notice
of such non-performance and Gatherer shall have thirty (30) Days to remedy
such non-performance. Should Gatherer fail to remedy the non-performance
Producer shall have the option to purchase Gatherer's Facilities based on
Gatherer's projected cash flow discounted at a fifteen percent (15%) present
value over twenty (20) years. In no event shall the amount paid by Producer
to Gatherer for Gatherer's Facilities be less than one hundred fifty percent
(150%) of Gatherer's original book value for Gatherer's Facilities.

2.       POINT(S) OF DELIVERY, PRESSURE AND OWNERSHIP

         A.   The "Point(s) of Delivery" for all Gas delivered under the
Agreement shall be at the discharge of Producer's individual wellhead valves.

         B.   Producer, at its own expense, shall equip, maintain and operate
all facilities to deliver Producer's Gas to Gatherer at the Point(s) of
Delivery, including, but not limited to, installation and maintenance of
Producer's gathering facilities and mechanical separation equipment

         C.   Except as otherwise provided in the Agreement, Gatherer shall
construct, maintain, own and operate all necessary facilities to accept
Producer's Gas from Producer at the Point(s) of Delivery. Gatherer shall keep
Gatherer's Facilities reasonably clear of obstruction.

         D.   Gatherer has designed the original facilities to maintain
between 0 and 2 psig of pressure at the suction of the compressor described
in Article II.A of the Agreement and will similarly design facilities under
Article II.B. Provided Producer's production does not materially deviate from
such design specifications, if the Monthly average suction pressure when the
compressor is operating is greater than 2 psig, Gatherer shall take immediate
steps to reduce said pressures and shall inform Producer of the nature of
such steps. If Producer's production does materially deviate from the design
specifications, Gatherer may not be able to maintain the referenced suction
pressure; however, the Parties will work together to address any resulting
pressure issues. Furthermore, in the event Producer determines other
conditions on Gatherer's Facilities are excessively limiting production,
Producer shall provide written notice to Gatherer and Gatherer shall have
thirty (30) Days to provide in writing a suggested remedy to alleviate said
conditions. If Gatherer's suggested remedy is unacceptable to Producer,
Producer shall have the right to install the necessary facilities for remedy,
at Producer's sole cost and expense.

                                       2.A

<PAGE>

         E.   Producer shall deliver Gas at the Point(s) of Delivery at a
pressure sufficient to enter Gatherer's Facilities, but not to exceed the
maximum allowable operating pressure ("maop") of the pipe. Gatherer shall not
be obligated to redeliver the Gas at pressures which exceed 100 psig for Gas
that is redelivered to Redelivery Point(s) demanding the******** gathering
fee and 1,250 psig for Gas that is redelivered to Redelivery Point(s)
demanding the ******** gathering fee as set forth in Article IV.A and IV.A.1
of the Agreement. Should the Parties elect to utilize only the proposed
"Thunder Creek" Redelivery Point and should Gatherer's Facilities be designed
to redeliver Gas at approximately 500 psig, the Parties agree to discuss
reduction of the gathering fee to such Redelivery Point.

         F.   As between the Parties, Producer shall be in possession and
control of the Gas deliverable under the Agreement and responsible for any
injury or damage caused thereby until the same shall have been delivered to
Gatherer, after which delivery Gatherer shall be deemed to be in exclusive
possession and control thereof and responsible for any injury or damage
caused thereby.

3.       RESERVATIONS AND COVENANTS OF PRODUCER

         A.   Producer, as a reasonable and prudent operator, hereby expressly
reserves the following rights with respect to Producer's interest in the Subject
Lands:

              1)    The right to use the Gas produced from the Leases prior to
                    delivery to Gatherer for the following purposes:

                    a)    For fuel in the drilling, development and operation of
                          the Subject Lands from which the Gas is produced, or
                          within the boundaries of any unit plan or operation to
                          which any portion of the Leases may be committed,
                          excluding, however, the use of such Gas for secondary
                          or tertiary recovery projects;

                    b)    For delivery to the lessors of the leases of the Gas
                          if such lessors are entitled to use or take such Gas
                          in kind under the terms of the leases and agreements
                          associated with the Subject Lands;

                    c)    For fuel in the operation of the facilities which
                          Producer may install in order to deliver Gas hereunder
                          in accordance with the terms hereof.

              2)    The right to pool or unitize the Subject Lands (or any
                    portion thereof) with other lands and leases so long as such
                    action does not reduce Producer's interest in the Subject
                    Lands. In the event of any such pooling or unitization, the
                    Agreement will cover Producer's interest in the pool or unit
                    and the Gas attributable thereto to the extent that such
                    interest is derived from Producer's Subject Lands.

         B.   Producer shall provide to Gatherer all necessary information
whereby Gatherer can make the proper allocation herein called for or required
by Gatherer's normal and customary accounting practices or required by
Gatherer's normal and customary contract administration practices.

         C.   Producer shall operate the Subject Leases free of any control by
Gatherer, including without limitation, the right to make farmouts of any lease
subject to this Agreement, and to abandon any well and surrender any lease when
Producer deems the same no longer capable of producing Gas in commercial
quantities under normal methods of operation. Producer shall not be required to
produce any well or wells in any manner which in its sole judgment and
discretion would not constitute good operating practice, nor shall Producer be
obligated to drill additional wells or to deepen, repair or rework any existing
wells.

4.       PRODUCER'S WARRANTIES

         A.   The Parties recognize that uncertainties may exist with respect to
ownership of coalbed methane gas. However, as between the Parties hereto,
Producer warrants that Producer has the right to deliver said Gas and that such
Gas is free from all liens and adverse claims, including liens to secure
payments of production taxes, severance taxes, and

                                       3.A

<PAGE>

other taxes. Producer agrees to indemnify Gatherer and save it harmless from all
suits, actions, debts, accounts, damages, costs, losses and expenses arising
from or out of adverse claims, whether meritorious or not, of any and all
persons, firms, or corporations to said Gas or to royalties, overriding
royalties, taxes, license fees, or charges thereon, resulting from actions of,
by, through or under Producer. Gatherer shall be entitled to recover all costs
and reasonable attorneys' fees incurred as a result of its involvement in any
action or claim described herein.

5.      EASEMENTS

         A.   To the extent that it may contractually or lawfully do so under
its leasehold interest without impairing its own similar right, Producer
hereby assigns and transfers to Gatherer any easement across the Producer's
Subject Lands, and across any adjoining lands in which Producer may have an
interest, for the purposes of installing, using, inspecting, repairing,
operating, replacing, and/or removing Gatherer's pipe, meters, lines, and
other equipment used or useful in the performance of the Agreement It is
intended that any property of Gatherer placed in or upon any of such land
shall remain the personal property of Gatherer, subject to removal by it upon
the expiration or termination of the Agreement for any reason. Gatherer shall
have a reasonable time after the expiration or termination of the Agreement
to remove same. Gatherer shall indemnify and hold Producer harmless of and
from any and all claims and damages for all injuries to persons, including
death, or damage to property arising out of or incident to Gatherer's use of
the easement hereunder transferred to the extent said claim or damage shall
be the result of intentional acts of Gatherer, its employees, agents and
representatives or negligence legally imputable to Gatherer, its employees,
agents, and representatives.

6.       PIPELINE LOSS

         A.   Gatherer agrees to use ordinary care in gathering Producer's Gas
from the Point(s) of Delivery to the Redelivery Point(s) nominated. However, the
Parties understand and agree that certain losses in the Gas will occur and shall
be shared by and among Producer and other third parties whose gas is gathered to
the Redelivery Point(s), in the proportion that each party delivers gas into
Gatherer's Facilities at their respective Master Meter(s). Pipeline Loss shall
be determined by subtracting the total Mcf's measured at the Redelivery Point(s)
from the total Mcf's measured at all Master Meter(s) less actual Fuel Gas
consumed in Gatherer's Facilities.

         EXAMPLE OF PIPELINE LOSS CALCULATION:
         (Master Meter Mcf - Actual Fuel Gas Consumed) - Redelivery Point(s)
         Mcf's = Pipeline Loss(/Gain)

         Pipeline Loss shall be calculated on a twelve (12) Month rolling
average beginning with the first Month following initial deliveries. The
twelve (12) Month rolling average Pipeline Loss for Gas shall not be greater
than three percent (3%) of the Gas measured at the Master Meter(s). In the
event Pipeline Loss is greater than three percent (3%), Gatherer shall pay
Producer a price equal to Producer's weighted average sales price at the
Redelivery Point for which Producees proportionate share of the Pipeline Loss
Mcf's is in excess of three percent (3%). Said price shall be paid only for
the volumes in excess of three percent (3%).

7.       GAS MEASUREMENT AND QUALITY

         A. Gatherer, at its expense, shall furnish, install, operate and
maintain suitable measurement at Gatherer's WMFs and separate Master Meters
downstream of the WMFs including electronic flow measurement recording devices.
Each meter installed by Gatherer shall be a meter acceptable in the industry and
each meter shall be installed and operated in accordance with the requirements
of applicable provisions in ANSI/API 2530, "ORIFICE METERING OF NATURAL GAS"
(American Gas Association Gas Measurement Committee Report No. 3) of the Natural
Gas Department of the American Gas Association, as amended from time to time, or
by any other method commonly used in the industry and mutually acceptable to the
Parties. Any meter installed hereunder shall be open to inspection by Producer
at all reasonable times. The charts and records pertaining to measurement
hereunder shall be kept on file by Gatherer for a period of two (2) years for
the mutual use of the Parties. In the event any question arises as to the
accuracy of the measurement, the meter or meters shall be tested upon the demand
of either Party. The expense of any such special test shall be borne by the
Party demanding same if the meter registration is found to be correct, and by
Gatherer if found to be incorrect.

                                       4.A

<PAGE>

         B.   Producer may, at its option and sole expense, install, maintain
and operate check meters and other equipment to check Gatherer's meters;
provided, however, that such check meters and other equipment shall be
installed by Producer so as not to interfere with the operation of any of the
Gatherees Facilities. Gatherer and Producer shall have access to each other's
measuring equipment at all times during business hours, but the reading,
calibrating and adjustment thereof and the changing of charts shall be done
only by the employees or agents of Gatherer and Producer, respectively, as to
meters or check meters so installed hereunder.

         C.   At least semi-annually, unless otherwise required by statute,
Gatherer shall verify the calibration of all meters installed hereunder and make
adjustments as necessary. Should Producer so desire, Gatherer shall give notice
to Producer of the time of such calibrations sufficiently in advance of holding
same in order that Producer may have its representative present. With respect to
any test made hereunder, a registration within two percent (2%) of correct shall
be considered correct. However, the meter or meters, when found to be incorrect,
shall be adjusted to one hundred percent (100%) accuracy as soon as possible.
Settlement for any period during which the meter registration deviates by more
than two percent (2%) of correct shall be corrected at the rate of inaccuracy
for any period of inaccuracy which is definitely known or agreed upon; but in
case the period is not definitely known or agreed upon, then either for a period
of fifteen (15) Days prior to the date of said test, or for a period calculated
from the beginning of the Accounting Period in which the test was conducted,
whichever is longer. The rate of the inaccuracy shall be estimated and agreed
upon by the Parties hereto on the basis of the best available data, using the
first of the following methods which is feasible:

              1)    By using the registration of any check meter or meters if
                    installed and accurately registering; or, in the absence
                    thereof,

              2)    By calibration, test, or mathematical calculation; or

              3)    By estimation based on comparison of the quantity of
                    deliveries with deliveries during preceding periods
                    under similar conditions when the meter was registering
                    accurately.

         D.   All fundamental constants, observations, records and procedures
involved in the determination and/or verification of the quantity and other
characteristics of Gas measured hereunder, unless otherwise specified herein,
shall be in accordance with the applicable provisions in ANSI/API 2530, "ORIFICE
METERING OF NATURAL GAS" (American Gas Association Gas Measurement Committee
Report No. 3) of the Natural Gas Department of the American Gas Association, as
amended from time to time, or by any other method commonly used in the industry
and mutually acceptable to the Parties. The average local atmospheric pressure
shall be assumed to be 12.7 Psia. The temperature of Gas flowing through each
meter shall be determined by a recording thermometer, installed by Gatherer at
its sole cost and expense to properly record the temperature of the flowing Gas,
and the arithmetical average of the temperature recorded while the Gas is
flowing during each meter chart interval shall be used in correcting amounts
delivered hereunder to a temperature base of sixty degrees Fahrenheit (60DEGF)
and to a pressure base of 12.7 pounds Psia. Should the recording thermometer
malfunction, Gatherer shall assume a reasonable temperature for the period in
question.

         E.   Producer agrees that Gas delivered to the Redelivery Point(s)
shall comply with the most stringent quality specifications of the downstream
pipelines. To the extent the downstream pipelines is willing to accept
non-conforming Gas, Gatherer will gather and redeliver such non-conforming
Gas. To the extent the downstream pipelines will only accept a certain
quantity of non-conforming Gas, Gatherer will gather and redeliver such
quantities of non-conforming Gas.

         F.   Gatherer may test Producer's Gas delivered hereunder for adherence
to the specifications referenced above, such testing to be in accordance with
generally accepted industry standards and procedures. If the Gas so delivered by
Producer does not meet the specifications set forth above, Gatherer, at its
option, may refuse to accept delivery of said Gas into its Facilities. If
Producer shall deliver Gas to Gatherer which exceeds the maximum pressure
specifications, or fails to meet the quality specifications above-referenced,
Producer shall be responsible for any damages caused to Gatherer's Facilities
and any other damages resulting from Producer's delivery of such non-conforming
Gas. In such event, Producer shall have the right to conform Producer's Gas to
the above specifications. Should Producer fail to do so, Gatherer, at its
option, may elect to accept such nonconforming Gas, condition the same to
conform to the above specifications and charge Producer a mutually acceptable
conditioning fee. If neither Party elects to condition the Gas to conform to the
above specifications, then Producer, at its option, and upon sixty (60) Days
prior written notice to

                                       5.A

<PAGE>



Gatherer, shall have the right to obtain the release of such non-conforming Gas
from the Agreement, but only as to the formation from which said Gas is
produced. Notwithstanding anything hereinabove to the contrary, should Gatherer
elect to accept and pay for nonconforming Gas, Gatherer shall not be deemed to
have waived any of its rights hereunder and shall nevertheless be entitled, at
any time and from time to time, to enforce the quality provisions hereof and
refuse to accept delivery of any volumes of non-conforming Gas from Producer.

         G.   At least semi-annually, unless otherwise required by statute,
Gatherer shall take samples from each of Producer's wells at the WMF's and have
such samples analyzed by chromatograph analysis to determine the liquids content
by component and the Gross Heating Value of such Gas. Gatherer shall have the
right to take and analyze a spot Gas sample prior to the regularly scheduled
sampling. Additionally, upon Producer's written request to Gatherer and at
Producer's sole cost, risk and expense, Gatherer shall take and analyze Gas
samples more frequently. All Gas samples taken hereunder shall be taken at such
times that are reasonably mutually agreeable so that the sample will be
representative of the Gas produced, shall be analyzed using the most current Gas
Processor's Association Publications and Producer shall be permitted to be
present for such sampling and permitted to take a split sample. The test samples
shall be analyzed through the use of a calorimeter (acceptable to both Parties)
that employs the Thomas Principle of Calorimetry described in Research Paper
#519, published by the U.S. Department of Commerce or by the use of gas
chromatography equipment The Gross Heating Value calculation will use the Btu
values assigned to the various hydrocarbon components as adjusted and updated
from time to time by Gatherer using as a base those values set forth in the most
current GPA Publication 2145 in effect at the time the Gross Heating Value
calculation is derived under the provisions of the Agreement Measurement shall
be determined as delivered on a saturated basis or consistent with the basis
applied to all producers delivering gas to Gatherer's Facilities. Gatherer shall
furnish Producer advance notice of the sampling and analysis of the Gas in order
that Producer may witness same. If Producer's representative is not present,
Gatherer shall proceed with the taking and analysis of samples. All gas which
may be delivered by third parties to Gatherer's Facilities shall be tested and
the hydrocarbon content thereof determined or caused to be determined by
Gatherer, using the same sampling and test methods.

         H.   Measurement of the redelivered Gas will be accomplished by
suitable meters installed, maintained and operated by the third party
receiving pipeline company(ies). Gatherer will perform periodic analysis and
joint meter tests semi-annually, unless otherwise required by statute, to
insure the third party receiving pipeline company's(ies') compliance with
standard industry practices. Should Gatherer be refused the right to install
a check recorder on third party receiving pipeline company(ies) meter
tube(s), the three percent (3%) Pipeline Loss as set forth in Section 6.A
above shall be waived.

8.       ALLOCATION OF GAS

         A.   The volume received at each Point of Delivery shall be
allocated by multiplying the actual volumes measured at each Master Meter by
a fraction, the numerator of which is the volume attributable to each
particular Point of Delivery, and the denominator of which is the total
volume attributable to all Points of Delivery behind each Master Meter.
Further, the MMBtu's received at each Redelivery Point shall be allocated by
multiplying the actual MMBtu's received at the Redelivery Point(s) by a
fraction, the numerator of which is the MMBtu attributable to each particular
Master Meter, and the denominator of which is the total MMBtu attributable to
all Master Meters into Gatherer's Facilities.

9.       PRODUCER'S REPRESENTATIVE

         A.   The Producer shall designate a representative with respect to all
matters under the Agreement, including but not limited to the following:

              1)    To give and receive all notices;

              2)    To make and witness any tests to be made of Producer's Gas
                    and measuring equipment and adjustments to such equipment;

              3)    To deliver the quantities of Producer's Gas deliverable
                    hereunder;

                                       6.A

                    any duly constituted authority having jurisdiction.

         B.   Gatherer may act, and shall be fully protected in acting, in
reliance upon any and all acts and things done and performed by or agreements
made with respect to all matters dealt with herein by said representative on
behalf of Producer as fully and with the same effect as though Producer had
done, performed, made or executed the same.

         C.   Producer may change its representative designated above, or
designate a new representative from time to time by delivery of written notice
of change and designation of representative to Gatherer. The representative so
designated shall have and may exercise all power and authority therein granted
with like effect as though named as such representative herein in the first
instance.

10.      REGULATORY BODIES

         A.   The Agreement is subject to all present and future valid laws and
lawful orders of all regulatory bodies now or hereafter having jurisdiction of
the Parties, or either of them; and should either of the Parties, by force of
such law or regulation imposed at any time during the term of the Agreement, be
ordered or required to do any act inconsistent with the provisions of the
Agreement, the Agreement shall continue nevertheless and shall be deemed
modified to conform with the requirements of such law or regulation for that
period only during which the requirements of such law or regulation are
applicable. Nothing in the Agreement or this Appendix shall prohibit either
Party from obtaining or seeking to obtain modification or repeal of such law or
regulation or restrict either Party's right to legally contest the validity of
such law or regulation, and each Party reserves the right to file with such
regulatory bodies any material necessary to implement the terms of the Agreement
and this Appendix as they existed prior to the modification.

11.      FORCE MAJEURE

         A.   Except for Gatherer's and Producees respective obligations to make
proper settlement, accounting and distribution of proceeds to all interest
owners as provided above for Gas delivered to and gathered by Gatherer under the
Agreement, in the event either Gatherer or Producer is rendered unable, by
reason of an event of force majeure, to perform, wholly or in part, any
obligation or commitment set forth in the Agreement, then upon such Party giving
notice and full particulars (including all supporting documentation) of such
event as soon as practicable after the occurrence thereof, the obligations of
both Parties shall be suspended to the extent and for the period of such force
majeure provided that the Party claiming an event of force majeure shall make
all reasonable attempts to remedy the same with all reasonable dispatch.

         B.   The term "FORCE MAJEURE", as used herein, shall mean acts of God,
strikes, lockouts or industrial disputes or disturbances, civil disturbances,
arrest and restraint of rulers or people, interruptions by government or court
orders, necessity for compliance with any present and future valid orders of
court, or any law, statute, ordinance or regulation promulgated by any
governmental or regulatory authority having proper jurisdiction, acts of the
public enemy, wars, riots, blockades, insurrections, including inability to
secure materials by reason of allocations promulgated by authorized governmental
agencies, epidemics, landslides, lightning, earthquakes, fires, storms, floods,
washouts, inclement weather which necessitates extraordinary measures and
expense to construct facilities and/or maintain operations, explosions, partial
or entire failure of Gas supply, breakage or accident to machinery or lines of
pipe, freezing of wells or pipelines, inability to obtain or delays in obtaining
easements or rights-of-way, the shutting in of facilities for the making of
repairs, alterations or maintenance to wells, pipelines or plants, the
interruption or suspension of the receipt of Gas deliveries hereunder by
Gatherer due to the declaration of force majeure by third-party transporters, or
any other cause whether of the kind herein enumerated or otherwise, not
reasonably within the control of the Party claiming force majeure.

         C.   Neither Party shall be entitled to the benefit of the
provisions of this Section 11 under either or both of the following
circumstances:

               1)   To the extent that the failure was caused by the Party
                    claiming suspension having failed to remedy the condition
                    by taking all reasonable acts, short of litigation, if
                    such remedy requires litigation, and having failed to
                    resume performance of such commitments or obligations
                    with reasonable dispatch; or,


                                       7.A

<PAGE>

              2)    If the failure was caused by lack of funds, or with respect
                    to the payment of any amount or amounts then due hereunder.

         D.   Settlement of strikes and lockouts shall be entirely within the
discretion of the Party affected, and the duty that any event of force majeure
shall be remedied with all reasonable dispatch shall not require the settlement
of strikes and lockouts by acceding to the demands of the Parties directly or
indirectly involved in such strikes or lockouts when such course is inadvisable
in the discretion of the Party having such difficulty.

         E.   If volumes of Producer's Gas are destroyed by an event of force
majeure while in Gatherer's possession, the obligations of both Parties under
this Agreement shall terminate with respect to the volumes lost but Gatherer
shall make all reasonable efforts to minimize such lost volumes.

12.      DEFAULTS

         A.   It is covenanted and agreed that if either Party shall fail to
perform any of the covenants or obligations imposed upon it under and by virtue
of the Agreement or this Appendix, in addition to its other rights and remedies,
the other Party may terminate the Agreement by proceeding as follows:

              1)    The Party not in default shall cause a written notice to
                    be served on the other Party in default, stating
                    specifically the cause for terminating the Agreement, and
                    declaring it to be the intention of the Party giving
                    notice to terminate the same; thereupon, the Party in
                    default shall have thirty (30) Days after the service of
                    the aforesaid notice in which to commence to remedy or
                    remove the cause or causes stated in the notice for
                    terminating the Agreement. If within said thirty (30)
                    Days the Party in default fails to commence the steps
                    necessary to remove and remedy said cause or causes, or
                    fully indemnifies the Party not in default for any and
                    all consequences of such breach, then such notice shall
                    be withdrawn and the Agreement shall continue in full
                    force and effect

              2)    In case the Party in default does not commence steps
                    necessary to remedy and remove the cause or causes, or
                    does not indemnify the Party giving the notice for any
                    and all consequences of such breach, within said period
                    of thirty (30) Days, then the Agreement shall become null
                    and void from and after the expiration of said period.
                    Termination of the Agreement shall not preclude the
                    non-defaulting Party from pursuing all of its rights,
                    claims and demands or other relief from the defaulting
                    Party.

         B.   No waiver by either Producer or Gatherer of any default of the
other under the Agreement shall operate as a waiver of any future default,
whether of like or different character or nature, nor shall any failure to
exercise any right hereunder be considered as a waiver of such right in the
future.

13.      UNECONOMIC WELL CONNECTIONS

         A.   In the event Gas volumes available for delivery from any group or
pod of Producer's Wells hereunder become uneconomic to Gatherer in the exercise
of Gatherer's reasonable judgment, Gatherer agrees to release from dedication to
this Agreement the affected wells and the lease(s) to the extent of the drilling
and spacing unit(s) corresponding to such wells and/or lease(s). Alternatively,
Producer may nonetheless maintain the connection to Gatherer's facilities
provided the Parties agree upon the fees for the Gatherer's services to be
provided. In setting these fees, the Parties shall take into consideration the
breakdown of fees set forth in Article IV.


14.      UNECONOMIC OPERATION OF GATHERER'S FACILITIES

         A.   If, in the opinion of Gatherer, any part of Gatherer's
Facilities is or becomes uneconomic to operate due to its volume, quality,
governmental regulation or any other cause, upon ninety (90) Days advance
written notice to Producer, Gatherer may either modify or suspend operations
thereof, in which case Gatherer shall not be obligated to take delivery of
all or any portion of the Gas from Producer's Wells, so long as such
condition exists. For the purposes hereof,

                                       8.A

<PAGE>

"UNECONOMIC OPERATION" shall be defined as circumstances under which Gatherer's
revenues from any part of Gatherer's Facilities is insufficient to offset actual
operating costs thereof.

15.      LITIGATION - ATTORNEYS' FEES

         A.   In the event litigation arising out of the Agreement should be
initiated by any Party hereto, the prevailing Party, after the entry of a final
non-appealable order, shall be entitled to recover from the other Party, as a
part of said judgment, all court costs, fees and expenses of such litigation,
including reasonable aftomeys' fees.

16.      DAMAGES

         A.   Except as otherwise provided herein, whether or not occasioned
by a default or other breach of the Agreement, neither Party shall be liable
to the other for special, exemplary, or consequential damages, except as to
third-party claims, pursuant to the indemnification provisions of the
Agreement or this Appendix.

17.      GENERAL

         A.   The Parties hereto assume full responsibility and liability for
the maintenance and operation of their respective properties and agree to
indemnify and save harmless the other Party from all liability and expense on
account of any damages, claims or actions arising from any act or accident in
connection with the installation, presence, maintenance or operation of the
property or equipment of the indemnifying Party.

         B.   Producer agrees that Gatherer, its successors and assigns, shall
have the right, but not the obligation, at any time to redeem for Producer, its
successors and assigns, or other interest owners by payment of any taxes, deeds
of trust, judgments or other liens on the Subject Leases described in Exhibit
"B" hereto, on Producer's Gas reserves or the production therefrom, in the event
of default of payment by Producer or other interest owners, and be subrogated to
the rights of the holder or holders thereof.

         C.   Upon consent of Gatherer, the Agreement may be ratified and
adopted by any owner of an interest in the Subject Lands, or any leases with
which the Subject Lands may be pooled or unitized, by execution and delivery
to Gatherer of a separate written instrument ratifying and adopting the
Agreement insofar as said owner's interest in any such lands or leases is
concemed, all the terms and provisions of the Agreement shall be binding upon
such interest owner. In addition, upon Gatherer's request, Producer shall use
reasonable efforts to encourage each interest owner in the Leases to execute
and deliver to Gatherer a ratification of the Agreement.

         D.   Each party executing or ratifying the Agreement makes and enters
into the Agreement severally and not jointly with other parties, and they are
not acting as partners, joint venturers, or otherwise jointly in this
transaction, and nothing herein contained or provided shall operate to create,
or be construed as creating, any such relationship. lt is expressly provided
that there shall never be any joint liability against the Parties designated
herein as Producer and that no single party shall be liable for the acts or
omissions of any other single party and any other gathering agreement entered
into with Gatherer shall be deemed to be a separate agreement.

         E.   The Parties agree that they will maintain the Agreement, and all
parts and contents thereof, in strict confidence, and that except for their
direct consultants (i.e., attorneys, accountants, bankers) or other working
interest owners for whom operator is marketing their pro rata share of
production or prospective purchasers of Producer's assets, all of whom agree to
be bound by this confidentiality provision, Producer and Gatherer will not cause
or permit disclosure of same to any third party without the express written
consent of the other Party; provided however, that disclosure by a Party is
permitted in the event and to the extent:

              1)    disclosing Party is required by a court or agency exercising
                    jurisdiction over the subject matter thereof, by order or by
                    regulation or law, to disclose; provided that in the event
                    either Party becomes aware of a judicial or administrative
                    proceeding that has resulted or may result in such an order
                    requiring disclosure, it shall (i) so notify the other Party
                    immediately (ii) utilize all reasonably available means to
                    limit the scope of the order or regulation requiring

                                       9.A
<PAGE>

                    disclosure, and (iii) take all actions reasonably
                    necessary to prevent disclosure to the public as a
                    result of disclosure to the court or administrative body,

              2)    disclosure is necessary to obtain transportation of the
                    Gas covered by the Agreement, or

              3)    disclosure is required in the course of routine audit
                    procedures.

              4)    disclosure is made for a press release which is
                    required to advise the public of the existence of the
                    Agreement without reference to specific terms hereof
                    other than the location and potential Gas volumes.

Any such disclosure shall be made upon the condition that the recipient shall in
turn hold such information confidential from further disclosure.

         F.   The Equal Employment Opportunity Clause required under Executive
Order No. 11246, the affirmative action commitment for disabled veterans and
veterans of the Vietnam Era, set forth in 41 CFR 60-250.4, the affirmative
action clause for handicapped workers, set forth in CFR 650-741.4, and the
related regulations of the Secretary of Labor, 41 CFR Chapter 60, are
incorporated by reference in the Agreement. By accepting the Agreement, Producer
certifies that it complies with the authorities cited above and that it does not
maintain segregated facilities or permit its employees to perform services at

         WHEREAS, Owner owns or controls certain natural Gas produced or to be
produced from the lands, leases and wells located in the Dedicated Area
("Dedicated Area") as more fully described on Exhibit "A" attached hereto; and

         WHEREAS, Gatherer intends to construct a gathering system in the
Dedicated Area.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements contained herein, Gatherer and Owner covenant and agree
as follows:

                                        I.
                                   DEFINITIONS

         As used herein, the following terms shall have the meanings set forth
         below:
         1.1  "Btu" - British Thermal Unit, or the quantity of heat required to
raise the temperature of one (1) pound of water one degree Fahrenheit (1DEGF) at
a starting temperature of 59.5 degrees Fahrenheit (59.5DEGF). "MMBtu" - one
million Btu's. Btu's at the Point(s) of Delivery and Receipt hereunder shall be
determined on an as delivered basis.

the next Month shall be deemed part of the first "Contract Year".
         1.3  "Dedicated Area" shall mean the area of dedication described on
Exhibit "A" in which Owner owns or controls certain natural gas produced or to
be produced from various lands, leases and wells which are dedicated to this
Agreement. For determining the fees due hereunder the Dedicated Area is divided
into the West Dedicated Area and East Dedicated Area. Such designation of West
Dedicated Area and East Dedicated Area is as shown on Exhibit "A".
         1.4  "Day" shall mean a period of twenty-four (24) consecutive hours
commencing at 9:00 a.m., Central Clock Time on one calendar day and ending at
9:00 a.m., Central Clock Time on the following calendar day.

<PAGE>

         1.5  "Fuel" or "fuel" shall mean Owner's share of the fuel that is
consumed, gas lost and unaccounted for and shrinkage on Gatherer's System
between the Point(s) of Receipt and the Point of Delivery. Owner's share of Fuel
shall be the sum of the following: (i) the total volume of fuel
consumed on each segment of the System during such Month times a fraction, the
numerator of which is the volume of Owner's gas which utilizes such segment and

event, be liable in damages of any kind, whether direct, indirect, incidental
or consequential, to Owner because of Gatherer's failure, inability or delay,
for any reason, to have constructed, installed and made available the
necessary facilities by any particular date to take delivery of Gas from the
Dedicated Area.
         2.4  Subject to the remaining terms and conditions of this Agreement,
Gatherer shall achieve each of the following: (i) commence purchase of right of
way for Gatherer's high pressure header in the East Dedicated Area on or before
April 15, 1999, (ii) order pipe for construction of Gatherer's high pressure
header in the East Dedicated Area on or before April 1 0, 1999, and (iii)
release of Gatherer's contractor to begin construction of Gatherer's high
pressure header or related appurtenances in the East Dedicated Area on or before
September 1, 1999, each of which is subject to delay due to the occurrence of an
event of force majeure. In the event Gatherer does not achieve one of the
foregoing objectives (as extended by an event of force majeure), Owner shall
have the option, upon sixty (60) days prior written notice to Gatherer, to
terminate this Agreement; provided, however, such notice shall be of no force or
effect if, within such sixty (60) day period, Gatherer is able to achieve such
objective.
         2.5  Owner reserves the following rights with respect to its interests
in the oil and gas properties committed by Owner to Gatherer under this
Agreement together with sufficient gas to satisfy such rights:
         a.   To operate Owner's oil and gas properties free from control by
Gatherer in such manner as Owner, in Owner's sole discretion, may deem
advisable, including without limitation, the right, but never the obligation, to
drill new wells, to repair and rework old wells, renew or extend, in whole or in
part, any oil and gas lease covering any of the oil and gas properties, and to
abandon any well or surrender any such oil and gas lease, in whole or in part,
when no longer deemed by Owner to be capable of producing gas in paying
quantities under normal methods of operation.

                                       -4-

<PAGE>

         b.   To use gas for developing and operating Owner's oil and gas
properties committed under this Agreement and to fulfill obligations to Owner's
lessors under those properties.
         c.   To pool, combine and unitize any of Owner's oil and gas properties
with other properties in the same field, and to alter such pooling, combination,
or units, in which event this Agreement will cover Owner's allocated interest in
unitized production insofar as that interest is attributable to the oil and gas
properties committed under this Agreement, and the description of property
covered hereby shall be considered to have been amended accordingly.

                                      III.
                              POD CONNECT CRITERIA

         3.1  From and after completion of Gatherer's high pressure gathering
headers in (1) the East Dedicated Area (for gas delivered at a Point of Receipt
in the East Dedicated Area), and (ii) the West Dedicated Area (for gas delivered
at a Point of Receipt in the West Dedicated Area), at the request of Owner,
Gatherer will (in accordance with the procedures and criteria set forth in
Section 3.2 and 3.3 below) extend its System and install necessary facilities to
connect a Pod, in the event such Pod has, as reasonably determined by Gatherer,
Gas reserves dedicated to this Agreement equal to one (1) Bcf for each mile of
pipe to be laid by Gatherer from its existing System to the Point of Receipt for
such Pod.
         3.2  In order for Gatherer to determine the reserves for each Pod,
Owner will notify Gatherer in writing of Owner's desire to connect a Pod and
will furnish Gatherer with any pertinent well data (i.e.- completion reports,
logs, etc.). Within fifteen (15) days of receipt of such request (with all
supporting well data), Gatherer will notify Owner, in writing of its election
to extend its System or not to extend its System. If Gatherer elects to
extend its System and connect such Pod, Gatherer will begin the activities
necessary for such connection within ten (10) days of such election and shall
proceed with due diligence to complete such connection. If Gatherer elects
not to extend its System, Owner may lay the pipe necessary, at its sole cost
and expense, to connect such Pod to Gatherer's System and Gatherer's charges
to Owner under this Agreement shall be adjusted as set forth in Section 3.4
hereof
         3.3  If Owner does not wish to lay the pipe necessary to connect such
Pod to Gatherer's System, Owner may: (i) cause Gatherer to install the necessary
pipe by paying Gatherer, in advance, for any and all costs (as determined by
Gatherer) to connect such Pod, or (ii) request in writing that up to 1600 acres
(comprised of up to ten wells in 160-acre spacing or twenty wells in 80-acre
spacing, as the case may be) actually connected to such Pod be released from
dedication under this Agreement. Gatherer will provide such release within
thirty (30) days of Owner's written request and will have no further obligations
hereunder relative to such wells and leases so released.

                                       -5-

<PAGE>

         3.4  In the event Gatherer has declined to make an interconnection into
its System as set forth in Section 3.2 and Owner has elected to make any such
interconnection, the fees payable under this Agreement with respect to such Gas
flowing through such interconnection shall be adjusted based on the following:
         a.   For an interconnection into Gatherer's System at any existing
Point(s) of Receipt - no change;
         b.   For an interconnection into Gatherer's System at a location
having a normal operating pressure above 25 psig but below 200 psig - the
gathering fee for such gas shall be reduced by ****** per Mcf; and
         c.   For an interconnection into Gatherer's System at a location
having a normal operating pressure at or above 200 psig - the gathering fee
for such Gas shall be reduced by ******** per Mcf.
         3.5  All interconnections made by Owner into Gatherer's System pursuant
to Section 3.2 shall be made at Owner's sole cost and expense at locations which
Gatherer reasonably determines will not adversely affect or impair operation of
Gatherer's System. In addition, Owner, at its sole cost and expense, shall cause
any such Gas connected by Owner to be delivered as follows: (i) against the
operating pressure of Gatherer's System at such location as such pressure may
exist from time to time, and (ii) with respect to Gas delivered into any segment
of Gatherer's System having a normal operating pressure at or above 200 psig, to
be dehydrated to not more than 5 pounds of water per million standard cubic feet

                                       IV.
                  CONTRACT QUANTITY, NOMINATIONS AND IMBALANCES

         4.1  Commencing with the completion of facilities for the initial
Point(s) of Receipt within the Dedicated Area and subject to the terms and
conditions of this Agreement, Gatherer shall receive from Owner all of Owner's
Gas tendered at the Point(s) of Receipt and shall redeliver Thermally Equivalent
Volumes at the Point of Delivery, less the applicable in kind Fuel reduction.
         a.   Although Gatherer agrees to employ accepted industry practices and
act as a prudent operator in the handling of Owner's Gas, the parties understand
and agree that certain volumetric gains and losses in the Gas will occur and
shall be shared by and among Owner and other third parties whose gas is gathered
on Gatherer's System, in the proportion that each party delivers Gas into
Gatherer's System at their respective Point(s) of Receipt. Gatherer will use
commercially reasonable efforts to minimize gains or losses on the System.
         b.   Gatherer shall not be obligated to receive, gather and deliver any
quantity of Gas which, when taken in addition to all other volumes of Gas which
Gatherer is obligated to gather

                                       -6-

<PAGE>

under any and all then existing gathering commitments, is in excess of the
design capacity or operating pressure of Gatherer's System.
         c.   Once Gatherer's System or a segment thereof is at capacity and
Owner has notified Gatherer of such constraint in writing, Gatherer shall not
enter into any new agreements which require utilization of capacity on such
segment(s) unless and until Gatherer expands its System or such segment can
accommodate additional volumes; provided, however, the parties expressly
acknowledge that this Section 4.1(c) shall not prevent Gatherer from
receiving Gas which is contracted for delivery to Gatherer's System
(including Gas produced from the drilling of additional wells) prior to such
notice.
         d.   If at any time and from time to time Gatherer is unable to gather
all of Owner's Gas from the Point(s) of Receipt for reasons other than a
violation of subparagraph (c) above, Gatherer will take Owner's Gas based on the
following priority: (i) Gatherer will take all volumes of gas on its System as
to which it has firm gathering commitments (including firm commitments to gather
Owner's Gas and gas from Gatherer's affiliates, if applicable) as a first
priority; (ii) in the event Gatherer has insufficient capacity on its System due
to an event of force majeure to satisfy all existing firm gathering commitments,
Gatherer will take all gas as to which it has such firm commitments on a
volumetrically prorated basis; and (iii) following satisfaction of all firm
gathering commitments, Gatherer will take all other gas (including Owner's Gas
and gas from Gatherer's affiliates for which no firm commitment exists) on a
volumetrically prorated basis. Prorations under the preceding sentence shall be
based on the daily nominated quantity of each source of gas up to the lower of
(A) the historical or calculated production capacity accepted by Gatherer for
such owners' interest in the wells that such owners have provided to support
their nominations, or (B) the quantity nominated for receipt under a purchase or
transportation agreement by the receiving party at the Point of Delivery, after
adjustment for Fuel. During such times Gatherer is unable to gather all of
Owner's Gas from the Point(s) of Receipt, Owner may deliver such Gas Gatherer is
unable to gather to systems other than Gatherer's System and may commit such Gas
to such other systems on a month to month basis; provided, however, once
Gatherer's System is again able to receive and deliver such volumes Gatherer
shall give written notice to Owner, whereupon Owner shall recommence deliveries
of such Gas to the System beginning on the first day of the Month immediately
following the end of thirty (30) days after Gatherer's notice. In the event
Gatherer's failure to take Owner's gas continues for sixty (60) consecutive days
(excluding the period following Gatherer's notice that it is again able to
receive and deliver volumes of Gas), except for conditions of quality or force
majeure, Owner may request (which request must be delivered, if at all, during
the continuation of such inability by Gatherer) that the volume from the
producing formations in the

                                       -7-

<PAGE>

existing wells which is in excess of the average quantity Gatherer was able
to gather during such sixty-day period be released from the dedication set
forth in Section 2.2. For example, if the average quantity of Owner's Gas
Gatherer was able to gather during such sixty-day period was 45,000 Mcfd,
then all production from the producing formations in the existing wells in
excess of 45,000 Mcfd shall be released. Upon request of Owner, Gatherer
shall release specific existing wells and the spacing units attributable
thereto which are impacted by the capacity constraint and which have a
combined production capacity (as determined at the time of Owner's request)
up to, but not to exceed, the volume released. A release under this
provision shall not apply to future wells (and the spacing units attributable
thereto) from which Gatherer is able to receive Gas at the time of drilling
and completion. Such release shall be Owner's sole and exclusive remedy for
Gatherer's failure to receive and gather any Gas dedicated hereunder for any
reason.
         4.2  Owner or Owner's designee shall provide Nominations to Gatherer as
required by Gatherer and will be responsible for all nominations and other
transportation arrangements beyond the Point of Delivery. Owner shall make or
cause its designee to make all arrangements with the downstream pipelines and
shall ensure that its desired Nominations for downstream pipeline transportation
are properly and timely placed with the downstream pipeline in accordance with
that pipeline's nomination and confirmation procedures.
         a.   For each Month during the term of this Agreement, Owner or Owner's
representatives will provide Gatherer written notice of Owner's Gas quantity
nominated for delivery at the Point(s) of Receipt and the Point of Delivery.
Owner's notice shall be based in good faith upon the producing ability of
Owner's well(s) for the upcoming Month, adjusted as necessary during the Month,
to bring cumulative receipts into line with cumulative redeliveries, and
adjusted to cover Fuel. To enable Owner to make its Nominations hereunder, prior
to initial deliveries and from time to time thereafter as reasonably deemed
necessary by Gatherer, Gatherer shall make a good faith estimate of the Fuel
(expressed as a percentage) to be consumed in operation of Gatherer's System.
Gatherer may at any time or from time to time during each Month adjust Owner's
Nomination quantity as necessary to conform to the above requirements and to
maintain balance. Except in the case of an emergency, Gatherer will notify Owner
prior to any such adjustments and shall give Owner a reasonable opportunity to
adjust its Nominations or flows and in the event Owner does not adjust its
Nominations or flows then and, in such event, Gatherer shall make such
adjustments. Gatherer shall have no obligation to accommodate any imbalances
caused by Owner's inability or failure to match Nominations with actual
performance. Complete Nomination information for the first of the Month
Nominations and the Nomination changes during the Month, including but not
limited to

                                       -8-

<PAGE>

downstream contract number, is due to Gatherer, on a normal business day,
twenty-four (24) hours prior to the downstream pipeline's nomination deadline.
         b.   Gatherer reserves the right to adjust these deadlines
reasonably in response to changes in the practices of pipelines downstream of
the Point of Delivery.
         c.   Gatherer is not obligated to assist Owner in resolving payment or
transportation disputes with pipelines downstream of the Point of Delivery or
Owner's customers other than to confirm the volumes delivered at the Point of
Delivery for Owner's account.
         d.   Owner shall have agents or employees available at all reasonable
times to receive from Gatherer's dispatchers advice and requests for changes in
the rates of delivery of Gas as required by Gatherer due to events of force
majeure, maintenance or repair of the System or other causes affecting the
operation or integrity of the System from time to time, and Owner will modify
its deliveries accordingly.
         4.3  It is recognized that because of dispatching and other variations,
certain imbalances may occur between volumes of Gas received by Gatherer
hereunder and the volumes of Gas delivered hereunder by Gatherer. However,
Gatherer shall use reasonable efforts to deliver to or for the account of Owner
each Day at the Point of Delivery a volume of Gas equal to Owner's Nomination
quantity for such Point of Delivery. Owner shall use reasonable efforts to keep
daily and monthly deliveries of Gas into Gatherer's System equal to Owner's then
current daily and monthly Nomination quantity for the Point(s) of Receipt.
         a.   The parties agree that during the term hereof Gatherer shall have
the right and obligation to operate its Gathering System and to receive and
deliver Gas hereunder in such a way as to maintain balance on its Gathering
System as between receipt and deliveries (after adjustment for Fuel) of Gas
subject to this Agreement as closely as possible. Gatherer will have the right
to refuse to accept volumes if Owner's production exceeds its Nominations, or to
refuse Nominations if such Nominations exceed production. The parties shall
cooperate to balance Thermally Equivalent Volumes of gas as nearly as feasible
on a daily basis.
         b.   Gatherer shall keep accurate records of the quantities of gas
nominated and scheduled for gathering, which records shall be reported to Owner
on a monthly basis. If Owner's gas is commingled with other gas at the Point(s)
of Receipt or at the Point of Delivery, the scheduling arrangements and
Gatherer's records shall include the allocations made at such Point(s) of
Receipt or Point of Delivery. Allocation of volumes between producers at the
Point(s) of Receipt shall be made as requested by the operator of the wells
connected to each Pod. Allocations at the Point of Delivery shall be made as
required by the downstream transporter at the Point of Delivery, or if

                                       -9-

<PAGE>

none, by Gatherer consistent with this Agreement. In no event shall Owner be
designated the swing party for any variances at the Point of Delivery.
         c.   For each Month, in its invoice to Owner for gathering services,
Gatherer shall include a statement of actual metered volumes at the Point(s)
of Receipt and Point of Delivery, Owner's allocation of such volumes, and the
difference between the quantity of Gas allocated to Owner at the Point(s) of
Receipt, less Fuel for such Month, and the quantity of Gas credited to Owner
at the Point of Delivery (the "Imbalance Quantity"). If the quantity of gas
received by Gatherer from Owner during a Month at the Point(s) of Receipt, as
adjusted for Fuel, exceeds the quantity of gas credited to Owner at the Point
of Delivery, the imbalance shall be cashed out by the payment by Gatherer to
Owner of an amount equal to the Imbalance Quantity times the Price Index. If
the quantity of gas credited to Owner during a Month at the point of Delivery
exceeds the quantity of gas received by Gatherer from Owner during a Month,
as adjusted for Fuel, the imbalance shall be cashed out by the payment by
Owner to Gatherer of an amount equal to the Imbalance Quantity times the
Price Index.
         d.   Gatherer will attempt to enter an operational balance agreement
with respect to deliveries into FUGG, on such terms and conditions as are
reasonable, customary, and acceptable to Gatherer.

                                       V.
                    DELIVERY PRESSURE AND REDELIVERY PRESSURE

         5.1  Owner shall deliver Gas to Gatherer hereunder at pressures
sufficient to effect delivery into Gatherer's System but not to exceed the
allowable operating pressure as determined solely by Gatherer. Owner shall
install pressure limiting devices of a design satisfactory to Gatherer to insure
over pressurization shall not occur on Gatherer's System. However, Owner shall
be solely responsible for pressure protection on any facilities operated by
Owner.
         5.2  Gatherer shall install equipment that is designed to maintain a
suction pressure at the inlet flange of the first compressor at or downstream of
each Point of Receipt of 5 psig and such equipment shall have the capability to
provide a suction inlet pressure of 2 psig under certain field operating
conditions. In addition, Gatherer will endeavor (without any additional cost or
expense to Gatherer) to maintain a suction pressure of 2 psig at the inlet
flange of the first compressor at or downstream of each Point of Receipt;
provided, however, that Gatherer shall have no liability for failure to maintain
a suction pressure of 2 psig. Except for circumstances constituting an event of
force majeure, during any Month where the average daily suction pressure at the
inlet flange of any such compressor exceeds 5 psig for a period in excess of two
(2) days during such Month, the fees payable during such Month with respect to
the Pod affected by such event shall be reduced

                                       -10-

<PAGE>

by******** per Mcf for every one (1) psig that the average monthly suction
pressure exceeds 5 psig, not to exceed a maximum of ******** per Mcf.
         5.3  Except as provided in Sections 3.5 and 5.2 above, neither Owner
nor Gatherer shall be obligated to install additional equipment (or continue
operation of such equipment once installed) to effect delivery of Gas to
Gatherer hereunder, but either Gatherer or Owner shall have the right to
install and operate equipment, if required. Any equipment installed and
operated by Owner shall be at its sole cost, risk and expense and shall (i)
be prior to delivery of Gas to Gatherer's System, and (ii) not interfere with
the operation (including gas measurement) of Gatherer's System.

                                       VI.
                             MEASUREMENT AND TESTING

         6.1  The volume of Gas received by Gatherer shall be measured at the
master meters immediately downstream of each Point of Receipt. The facilities to
measure the volume and quality of Gas delivered at the Point(s) of Receipt will
be owned, maintained and operated by Gatherer.
         6.2  The volume of Gas delivered by Gatherer at the Point of Delivery
shall be metered through a meter caused to be located by Gatherer at the Point
of Delivery.
         6.3  In the event that at any time, or from time to time, Gatherer
commingles Gas from Point(s) of Receipt with Gas from other than the Point(s) of
Receipt hereunder, Gatherer agrees to measure such other gas prior to its
entering Gatherer's System.
         6.4  The unit of measurement for Gas hereunder shall be one (1) cubic
foot of gas, and the term "cubic foot of gas" wherever used herein shall mean a
cubic foot of Gas at a temperature of sixty degrees Fahrenheit (60DEGF) and at a
pressure of fourteen and seventy-three hundredths (14.73) Psia.
         6.5  The Gas shall be metered downstream of the Point(s) of Receipt by
orifice meters which shall be constructed and installed in accordance with the
applicable provisions of the then current American Gas Association's Gas
Measurement Committee Report No. 3, as amended. Subject to the receipt of any
necessary governmental or regulatory approvals and authorizations, electronic
flow measurement recording devices (EFM) shall be installed at each of
Gatherer's master meters at the Points of Receipt. The volumes of Gas received
and delivered by Gatherer as measured at pipeline pressures and temperatures
shall be computed from the meter records and converted into the unit of
measurement specified above in accordance with the methods prescribed in the
then current Gas Measurement Committee Report No. 3 of the American Gas
Association, including the appendix thereto. Correction shall be made for
deviation from the Ideal Gas Laws at the pressure and temperature at which the
Gas is metered. To determine the factors for such correction a quantitative
analysis of the Gas shall be made at reasonable intervals, and such factors
shall be

                                       -11-

<PAGE>

obtained from data contained in the then current "Super-Compressibility
Factors for Natural Gas", Volumes 1 through 6, inclusive, or in "Tables for
the Determination of Super-Compressibility Factors for Natural Gas Containing
Nitrogen and/or Carbon Dioxide", Volume 7, as published by the American Gas
Association, or any subsequent revision thereof For the purposes of
measurement and meter calibration, the atmospheric pressure shall be assumed
to be twelve and seven-tenths (12.7) pounds per square inch, without regard
to variations in natural atmospheric pressure from time to time. Each EFM
unit will be equipped with communication equipment and Gatherer shall allow
Owner (or Owner's designee) remote electronic access to Gatherer's EFM data
for each master meter measuring gas from Owner hereunder. In the event
Gatherer has access to EFM data for deliveries into FUGG, Gatherer shall,
upon Owner's request, provide such EFM data with respect to Owner's volumes
of gas delivered into FUGG.
         6.6  The specific gravity of the Gas flowing through meters downstream
of the Point(s) of Receipt shall be determined by Gatherer at such intervals as
may be practicable under the circumstances, but at least semi-annually. All such
determinations of specific gravity shall be made by a standard gravity balance
in accordance with the provisions of the Natural Gas Processors Association
Publication No. 3130, entitled "Standard Method for Determining the Specific
Gravity of Gas", or by a gravitometer employing the "Momentum Method" of
specific gravity determinations as described in Chapter VII, "Determination of
Specific Gravity", of the then current American Gas Association Gas Measurement
Manual; or by standard calculation method using aforementioned Gas sample. The
specific gravity of the Gas flowing through each meter determined by either of
the above-mentioned methods shall be used in computing the volume of Gas
delivered through such meter. The specific gravity determined by any test shall
apply from the date the test was taken until the date of the next test.
         6.7  Temperature of the Gas gathered hereunder shall be determined by a
recording thermometer to record the temperature of the Gas flowing through each
meter, and the arithmetic average of the hourly temperatures recorded shall be
used in correcting the volumes delivered hereunder to the unit of measurement
specified above.
         6.8  The accuracy of Gatherer's measuring equipment shall be
verified by test, using means and methods generally acceptable in the gas
industry, at least semi-annually. Notice of the time and nature of each test
shall be given by Gatherer to Owner sufficiently in advance to pen-nit
convenient arrangement for Owner s representative to be present. Measuring
equipment found to be registering inaccurately shall be adjusted to read as
accurately as possible. If, after notice, Owner fails to have a
representative present, the results of the test shall nevertheless be
considered accurate until the next test. Gatherer shall, upon written request
by Owner, conduct a test of Gatherer's

                                       -12-

<PAGE>

measuring equipment, provided that in no event shall Gatherer be required to
test its equipment more frequently than once a month. All tests of such
measuring equipment shall be made at Gatherer's expense, except that Owner
shall bear the expense of tests made at its request if the inaccuracy is
found to be two percent (2%) or less.
         6.9  If for any reason any measuring equipment is inoperative or
inaccurate so that the volume of Gas delivered is not correctly indicated by
the reading thereof and, if such reading is in error by more than two percent
(2%) in the measurement of Gas, then the volume of Gas delivered, during the
period such measuring equipment is inoperative or inaccurate, shall be
determined by the parties hereto on the basis of the best data available
using the first of the following methods which is feasible:
         (i)   By using the registration of any check measuring equipment
               installed and accurately registering;
         (ii)  By correcting the error if the percentage of error is
               ascertainable by calibration, test or mathematical
               calculations; or
         (iii) By comparing deliveries made during preceding periods
               under similar delivery conditions when the meter was
               registering accurately.
         An adjustment based on such determination shall be made for such period
of inaccuracy as may be definitely known, or if not known, then for the lesser
of (i) one-half the period since the date of the last meter test or (ii) three
Months.
         6.10 Gatherer and Owner shall have the right to inspect equipment
installed or furnished by the other party, and the charts and other measurement
or test data of the other party, at all times during business hours; but the
reading, calibration and adjustment of such equipment and changing of charts
shall be done by the party installing and furnishing same. Unless the parties
otherwise agree, each party shall preserve all original test data, charts and
other similar records in such party's possession for a period of at least two
(2) years.
         6.11 In the event new technologies are developed and adopted by the
natural gas industry with respect to the measurement of volumes or determination
of gross heating value, Gatherer shall employ such technologies in connection
with operation of the System to the extent such technologies are economically
justified for the System, as determined by Gatherer acting in its reasonable
judgment.

                                      VII.
                             QUALITY SPECIFICATIONS

         Gas delivered by Owner hereunder shall be merchantable Gas conforming
to the following specifications:

                                       -13-

<PAGE>

         7.1  HEATING QUALITY, SULPHUR, CARBON DIOXIDE, OXYGEN, AND NITROGEN.
Gatherer may refuse to receive Gas with a Gross Heating Value of less than nine
hundred and fifty (950) Btu's. The Gas shall not contain any of the following in
excess of: one quarter (1/4) grain of hydrogen sulphide per hundred (100) cubic
feet; twenty (20) grains of total sulphur per hundred (100) cubic feet; four
percent (4.0%) by volume of carbon dioxide; ten parts per million (10 ppm) by
volume of oxygen; or three percent (3.0%) by volume of Nitrogen. Owner shall
make reasonable efforts to keep the Gas entirely free of oxygen.
         7.2  TEMPERATURE. The temperature of the Gas at the Point(s) of Receipt
shall not be in excess of one hundred twenty degrees (120DEG) Fahrenheit.
         7.3  WATER AND HYDROCARBON DEW POINT. Owner agrees that at the
temperature and pressure Gas is delivered hereunder it shall not contain any
hydrocarbon or non-hydrocarbon fractions which would condense to free liquids in
the pipeline at the operating pressure of Gatherer's System. The Gas shall not
contain any free H2O in the liquid state. Gatherer shall be responsible for any
additional dehydration required to meet any differing quality specifications of
downstream pipelines.
         7.4  MISCELLANEOUS. The Gas shall be commercially free of solids, sand,
dust, gums, crude oil, water and hydrocarbons in the liquid phase, and other
objectionable substances which may be injurious to pipelines or which may
interfere with the transmission or commercial utilization of said Gas.
         7.5  QUALITY GUIDELINES. Notwithstanding the above all Gas delivered
hereunder shall conform to the then current quality specifications, standards
and/or tariff requirements of any downstream pipeline for heating quality,
sulphur, carbon dioxide, oxygen and nitrogen (or any other quality
specifications not covered in this Agreement that are specified in such
downstream pipeline's then current tariff), subject, however, to the following
exceptions: Gatherer will accept gas for delivery on its System (A) with Gross
Heating Value less than the specification contained in this Agreement or the
specification of any applicable downstream pipeline or (B) a nitrogen content in
excess of the specification contained in this Agreement or the specification of
any downstream pipeline to the extent, and only to the extent, with respect to
either event in clause (A) and (B) such downstream pipeline accepts such gas. In
the event any downstream pipeline refuses to accept Owner's gas for failure to
meet the specifications in clause (ii) above, then Gatherer may, at its option,
reject such gas under this Agreement. In addition, should Owner's gas have a
carbon dioxide content (as measured at any Point of Receipt) in excess of four
percent (4%), Gatherer shall accept such gas to the extent, and only to the
extent, (i) such gas, when commingled with other streams of gas, is in
compliance with such specification, and (ii) Gatherer determines, acting in its
sole

                                       -14-

<PAGE>

discretion, that a carbon dioxide content in excess of four percent (4%) is
not detrimental to its System (or any part thereof).
         7.6  TESTS. Tests to determine the total sulphur, hydrogen sulphide,
carbon dioxide, oxygen and water vapor content of the Gas at the Point(s) of
Receipt shall be made by Gatherer by approved standard methods in general use in
the gas industry. Such tests shall be scheduled and made at the same time as are
the meter tests provided for in Article VI hereof, or as frequently as deemed
necessary by Gatherer.
         7.7  SUB-QUALITY GAS. Whenever the quality of the Gas delivered by
Owner hereunder does not conform to the quality specifications contained
herein, Gatherer shall have the night, upon notice to Owner, to: (i)
discontinue or cur-tail Gatherer's receipt of Owner's Gas hereunder, or (ii)
condition such off specification Gas and charge Owner a competitive rate for
such conditioning; provided, however, that Gatherer shall not unduly
discriminate against Owner with respect to curtailment or conditioning as
compared to other parties on Gatherer's System which are similarly situated
on the same segment of Gatherer's System. In the event Gatherer elects not to
condition Owner's Gas or in the event the rate at which Gatherer proposes to
condition such Gas is not competitive then, and in either such event, Owner
shall have the option to condition such Gas to make it conform to the quality
specifications of this Agreement; provided, however, if Owner elects to
condition its Gas, nothing contained in this Agreement shall obligate
Gatherer to pay for any such conditioning.
         If neither Gatherer nor Owner treats Gas produced from a well(s) which
does not conform to the quality specifications of this Agreement and Gatherer
chooses not to accept such Gas, then at the written request of Owner, Gatherer
shall release from the provisions of this Agreement up to 1600 acres (comprised
of up to ten wells on 160-acre spacing or twenty wells on 80-acre spacing, as
the case may be) actually connected to the Pod which is producing off
specification Gas.

                                      VIII.
                                     CHARGES

         8.1 Subject to the provisions hereof, for each Point of Receipt
hereunder Owner shall pay Gatherer as follows:
         (i)   For Gas delivered by Owner to Gatherer at
               Point(s) of Receipt located in the East Dedicated Area, Owner
               shall pay Gatherer ******** per Mcf of Owner's Gas received.
         (ii)  For Gas delivered by Owner to Gatherer at Point(s) of
               Receipt located in the West Dedicated Area, Owner shall pay
               Gatherer ******** per Mcf of Owner's Gas received.

                                       -15-

<PAGE>

         8.2  The rates set forth in Section 8.1 (as adjusted for reductions,
if any, pursuant to Section 3.4) above shall be adjusted commencing on the
first day of the Month following the first anniversary of the date of first
deliveries of Owner's Gas into Gatherer's System, and annually thereafter, by
multiplying the applicable gathering fee then in effect by a fraction, the
numerator of which is the CPI Index for January of the year in which such
calculation is made, and the denominator of which is the CPI Index for
January of the immediately preceding year. "CPI Index" shall mean the
Consumer Price Index for All Urban Consumers ("CPl-U") as published for such
Month by the U.S. Department of Labor.  In no event shall the gathering fees
due hereunder ever be less than the rate(s) set forth in Section 8. 1.
         8.3  Notwithstanding the terms of Section 8.1 above, in the event
Gatherer provides gathering service on the System to a third party pursuant to
an agreement with a primary term exceeding fifteen (1 5) years at rates for
"Comparable Service" (as hereafter defined), lower than those set forth in this
Agreement, then Owner's rates herein shall automatically be adjusted as follows:
all rates otherwise payable by Owner under this Agreement for service in the
applicable portion of the Dedicated Area (i.e. the East Dedicated Area or the
West Dedicated Area, as applicable) shall be multiplied times a fraction, the
numerator of which is the rate charged to such third party for Comparable
Service and the denominator of which is the rate charged to Owner under this
Agreement for such service. For purposes of this Section 8.3, "Comparable
Service" shall mean gathering service provided to third parties in the same
portion of the Dedicated Area (i.e. the East Dedicated Area or the West
Dedicated Area) and at interconnections into Gatherer's System within the same
parameters set forth in Section 3.4. For example, in the event Gatherer extends
gathering service for receipt into Gatherer's System in the East Dedicated Area
under the parameters set forth in Section 3.4(a) at a rate of *********, then
all rates payable by Owner for service in the East Dedicated Area shall be multi
lied by the fraction ******** and rates in the West Dedicated Area would not be
reduced. As a second example, in the event Gatherer extends gathering service
for receipt into Gatherer's System in the East Dedicated Area under the
parameters set forth in Section 3.4(b) at a rate of ********, then all rates
payable by Owner for service in the East Dedicated Area shall be multiplied by
the fraction ******** and rates in the West Dedicated Area would not be reduced.
Rates payable by Owner for service in the East Dedicated Area or the West
Dedicated Area, as applicable, shall not be reduced unless Gatherer has given a
lower rate to the third party for service in such area.
         8.4  Owner shall have the option, to be exercised in writing no later
than thirty (30) days prior to the end of each Contract Year to convert to firm
service a portion of the gathering service to be rendered under this Agreement
(such election to be effective on the first day of a Month

                                       -16-

<PAGE>

specified in Owner's notice during the immediately succeeding Contract Year).
For such firm service, Owner shall pay Gatherer, in lieu of the charges per
Mcf set forth in Section 8.1, an advance monthly demand charge equal to the
applicable per unit charge in Section 8.1 multiplied by a quantity determined
in this Section 8.4. Owner may exercise its option to convert to firm service
for a quantity of up to fifty percent (50%) of Owner's average monthly usage
of gathering services hereunder for the Contract Year during which Owner's
notice is delivered; provided, however, that Owner's election to convert to
firm service shall not be cumulative from one Contract Year to the next and
Owner may not reduce its commitment for firm service from one Contract Year
to the next; and, further provided, in no event shall Owner ever be entitled
to firm gathering service during any given Month or on any given Day, as
applicable, for a quantity in excess of 900,000 Mcf/Month or 30,000 Mcf/Day.
Notwithstanding the other terms of this Section 8.4, Owner shall not be
entitled to (and Gatherer shall not be obligated to provide) firm gathering
service at any time from and after January 1, 2010. Gatherer's receipts from
Owner shall be allocated first to Owner's firm gathering service and then to
its pro rata service under this Agreement.

                                       IX.
                         BILLING, PAYMENT AND REPORTING

         9.1  On or before the twentieth (20th) day of each Month after
deliveries of Gas commence hereunder, Gatherer shall render to Owner or Owner's
representative a statement for the preceding Month identified as to the Point(s)
of Receipt and Point of Delivery, showing the daily and total volumes of Gas
allocated to delivery hereunder, the amount due therefore and information
sufficient to explain and support any adjustments in volumes or amounts made by
Gatherer in determining the amount billed. The Owner or Owner's representative
shall pay Gatherer at the address shown hereunder on or before the last day of
each Month, or if the statement is rendered by Gatherer after the twentieth
(20th) day, within ten (10) days after receipt of such statement. If the correct
amount is not paid when due, interest on any unpaid portion of the correct
amount shall accrue at the lesser of: (i) the highest rate of interest permitted
by applicable law, or (ii) fifteen percent (15%) per annum. If any default
continues after thirty (30) days' written notice from Gatherer to Owner,
Gatherer may suspend receipt of Gas hereunder without prejudice to any other
available remedies at law or in equity.
         9.2  If any overcharge or undercharge in any form whatsoever shall at
any time be found and the bill therefore has been paid, Gatherer shall refund
any amount of overcharge, and Owner shall pay any amount of undercharge within
thirty (30) days after final determination thereof, provided that no retroactive
adjustment will be made beyond a period of two (2) years from the date a
discrepancy occurs.

                                       -17-

<PAGE>

         9.3  Both parties hereto shall have the night at any and all reasonable
times to examine the books and records of the other party to the extent
necessary to verify the accuracy of any statement or charge, computation, or
demand made pursuant to this Agreement.

                                       X.
                                      TAXES

         Owner agrees to reimburse Gatherer upon invoice for the full amount
of any taxes or charges (of every kind and character except corporate
franchise and excess profits taxes and taxes measured by net income) levied,
assessed or fixed by any municipal or governmental authority against Gatherer
or its business in connection with or attributable to the volumes, value or
gross receipts from the gathering of the Gas received from Owner hereunder or
against such Gas itself or the act, right or privilege of ownership,
production, severance, handling, transmission, compression, treating,
distribution, sale delivery or redelivery of such Gas, whether such tax or
charge is based upon the volume, value or gross receipts from the gathering
of such Gas or upon some other basis.

                                       XI.
                          CONTROL, POSSESSION AND TITLE

         11.1 Gatherer shall have no responsibility with respect to the Gas or
on account of anything which may be done, happen or arise, with respect thereto,
until the Gas is delivered into Gatherer's System at the Point(s) of Receipt
provided herein. Owner shall have no responsibility with respect to the Gas or
on account of anything which may be done, happen or arise, with respect thereto
after receipt thereof by Gatherer and prior to delivery thereof at the Point of
Delivery. After the delivery of Gas at the Point of Delivery, Gatherer shall
have no responsibility with respect to such Gas or on account of anything which
may be done, happen or arise with respect thereto.
         11.2 Owner represents and warrants to Gatherer that all Gas which Owner
causes to be delivered to Gatherer shall not have previously been transported in
interstate commerce or otherwise cause Gatherer's facilities to be subject to
jurisdiction of any regulatory authority.
         11.3 Owner warrants title to or the right to deliver all Gas delivered
hereunder, that it has the right to deliver same hereunder and that such Gas is
free from liens and adverse claims of every kind, and each agrees to indemnify
Gatherer from all suits, actions, debts, accounts, damages, costs, losses and
expenses arising from or out of adverse claims of any or all persons, including
governmental entities, as to said Gas or as to royalties or charges thereon or
as to the construction and/or operation of any facilities related to service
hereunder. Title to the Gas delivered or caused to be delivered by Owner to
Gatherer hereunder at the Point(s) of Receipt shall remain with Owner and shall
not pass to, nor vest in, Gatherer. The foregoing indemnity shall apply as to
any adverse claims concerning the ownership of coalbed methane as between the
coal estate and the oil and gas

                                       -18-

<PAGE>

estate but any such adverse claim shall not constitute a breach by Owner of
the warranty of title except to the extent of any deliveries by Owner
following an adverse and final, nonappealable court order.
         11.4 Each party agrees to indemnify and hold the other party harmless
from and against any and all suits, actions, damages, costs, losses and expenses
sustained by such other party relative to any breach by either party of the
covenants herein expressed.
         11.5 Gatherer will endeavor to keep its System clear of hydrocarbon
liquids and other obstructions. In consideration of such obligation, Owner
hereby conveys to Gatherer all right, title and interest in and to any
condensate attributable to Owner's gas which Gatherer may collect from the
System. Owner's initial production into the System shall consist solely of
natural gas produced from coalbed methane formations - for such production,
Owner and Gatherer believe that all liquid hydrocarbons, if any, shall remain
entrained in the natural gas stream and redelivered to Owner at the Point of
Delivery. It is possible that conventional natural gas production will be
delivered by Owner into the System the future - in such event (and to the extent
Gatherer collects condensate on its System which is attributable to Owner's
gas), Gatherer shall distribute to Owner a portion of the proceeds from any
sales of such condensate, calculated as follows: (i) the royalty percentage for
owner's Leases, times (ii) the total proceeds from such condensate sales
(propane and heavier only), times (iii) a fraction, the numerator of which is
the total theoretical hydrocarbon content (propane and heavier) attributable to
Owner's gas for the Month immediately prior to such sales and the denominator of
which is the total theoretical hydrocarbon content (propane and heavier)
attributable to all gas delivered to the System for such Month

                                      XII.
                                  FORCE MAJEURE

         12.1 In the event of either party hereto being rendered unable, wholly
or in part, by force majeure, to carry out its obligations under this Agreement,
then the obligations of the party experiencing such event of force majeure,
except for payment due, so far as they are affected by such force majeure, shall
be suspended during the continuance of any inability so caused, but for no
longer period, and such cause shall, to the extent possible, be remedied with
all reasonable dispatch. The party claiming force majeure shall give notice and
reasonable particulars thereof to the other party as soon as is reasonably
practicable and shall remedy the force majeure with reasonable diligence.
         12.2 The term "force majeure" as employed herein shall mean acts of
God, strikes, lockouts or other industrial disturbances, acts of the public
enemy, wars, blockades, military action, insurrections, riots, epidemics,
landslides, lightning, earthquakes, fires, storms or storm warnings,

                                       -19-

<PAGE>

crevasses, floods, washouts, arrests and restraints of government and people,
civil disturbances, explosions, breakage or accident to machinery or lines of
pipe, the necessity for testing or making repairs or alterations to machinery
or lines of pipe, freezing of well(s) or lines of pipe, failure of third
party transporters, inability to obtain easements and/or rights-of-way,
inability of any party hereto to obtain necessary materials, supplies or
pen-nits due to existing or future rules, regulations, orders, laws or
proclamations of governmental authorities (both Federal and State), including
both civil and military, and any other causes, whether of the kind herein
enumerated or otherwise, and whether caused or occasioned by or happening on
account of the act or omission of one of the parties hereto or some persons
or concern not a party hereto, not within the control of the party claiming
suspension, and which by the exercise of due diligence such party is unable
to prevent or overcome.
         12.3 It is understood and agreed that the settlement of strikes or
lockouts shall be entirely within the discretion of the party having the
difficulty, and that the above requirement that any force majeure shall be
remedied with all reasonable dispatch shall not require the settlement of
strikes or lockouts by acceding to the demands of the opposing party when such
course is inadvisable in the discretion of the party having the difficulty.

                                      XIII.
                                      TERM

         This Agreement shall become effective on the date hereof and shall
continue in full force and effect for twenty (20) Contract Years from the date
of the Agreement and continue year to year thereafter until canceled by either
party upon not less than ninety (90) days prior written notice.

                                      XIV.
                                   ASSIGNMENTS

         14.1 This Agreement shall extend to and be binding upon the parties
hereto, their successors, assigns, heirs, personal representatives and
representatives in bankruptcy and shall constitute a real night and covenant
running with the land and shall be binding upon any successor-in-interest to the
lands, leases and wells of Owner within the Dedicated Area or to Gatherer's
System including the easements and rights-of-way therefor. The interest of
either party may be assigned or conveyed in whole or in part from time to time.
No assignment or conveyance shall relieve the assigning party of any obligations
hereunder unless, and until, the assignee has delivered a ratification of this
Agreement as to the interest assigned. No transfer of, or succession to the
interest of any party hereto, wholly or partially, shall affect or bind any
other party until the other party shall have received written notice of such
transfer.

         14.2 Gatherer and Owner agree to execute a Memorandum of Contract (the
form of which is attached as Exhibit "B") for filing in the land records for the
Dedicated Area setting forth the dedication and other relevant terms and
conditions of this Agreement.

                                       XV.
                                  MISCELLANEOUS

         15.1 To the extent it is legally able to do so by virtue of its
lease, purchase contract or otherwise, Owner hereby grants to Gatherer an
easement and servitude on the leaseholds, properties and premises described
herein for the purpose of installing, operating and maintaining its System
with the right to remove same before or after the expiration of this
Agreement, and the right to free access to any part of said leaseholds,
properties and premises for any purpose connected with this Agreement.
Gatherer shall indemnify, defend and hold harmless Owner from any claims,
suits, actions, debts, accounts, damages, costs, losses and expenses arising
from or out of Gatherer's use of such easements and servitudes.
         15.2 The captions in this Agreement are for the convenience of the
parties in identification of the provisions hereof and shall not constitute a
part of the Agreement nor be considered in the interpretation of this Agreement.
         15.3 Failure to exercise any right or rights hereunder shall not be
considered a waiver of such right or rights at the time or in the future for
like failure to assert rights.
         15.4 The language of this Agreement shall not be construed in favor of
or against either Gatherer or Owner, but shall be construed as if the language
were mutually drafted by both parties. This Agreement constitutes the entire
understanding of the parties relating to the gathering of Gas and is intended to
be the final, exclusive and complete expression of their agreement and its
terms. No other representations, understandings, or agreements have been made or
relied upon in the making of this Agreement other than those specifically set
forth herein. There may be no modification or amendment hereof except by
writing, signed by both Gatherer and Owner.
         15.5 The parties agree and confirm that this Agreement shall be
governed by and construed in accordance with the laws of the State of Colorado,
excluding any conflicts-of-law rule or principle which might refer a matter to
the laws of another state, and that this Agreement was prepared by both parties
and not by either party to the exclusion of the other.
         15.6 Upon request, Owner shall furnish to Gatherer each month, copies
of any and all forms filed by Owner and/or the operator of any wells delivering
Gas hereunder which are reasonably requested by Gatherer in connection with
Gatherer's obligations to make filings with any regulatory body exercising
jurisdiction over production from the lands and leases described herein.

         against the operating pressures at the Delivery Point(s) as they from
         time to time exist; provided, Buyer agrees that it shall not cause the

         psig. If the average pressure at the Delivery Point exceeds 100 psig in
         any Accounting Period, then upon written notice by Seller of such

         Agreement, referred to below. In order to provide for coordinated
         nominations and balancing procedures under both this Agreement and
         under the Gas Sales Agreement, the parties are entering into the
         Nomination and Balancing Agreement of even date herewith; which shall
         be applicable to deliveries and receipts under this Agreement as well
         as under the Gas Sales Agreement.

                                       2

<PAGE>

         2.2      COMMITMENT AND QUANTITY.

         a.       Seller hereby commits, sells, and agrees to deliver to Buyer;
         and Buyer agrees to purchase and receive, or cause to be received for
         Buyer's account, from Seller, all gas attributable to the leasehold
         interests of Seller and produced from formations from the surface of
         the earth to the base of the Tertiary Age Coal Formations from wells
         now or hereafter located on the Lands, up to the lesser of (i) the then
         applicable Contract Capacity, or (ii) a quantity of gas equal to the
         quantity repurchased by Seller under the Gas Sales Agreement between
         the Pates of even date herewith (the "Gas Sales Agreement") plus
         Retained Fuel, as defined in the Gas Sales Agreement. Seller agrees
         that the foregoing dedication shall be a covenant running with the land
         and that any assignment, sale or other transfer of all or a portion of
         Seller's interests in the Lands shall include and be subject to the
         dedication under this Agreement. It is recognized that because of
         dispatching and other variations, certain differences may occur between
         the quantity of gas delivered to Buyer under this Agreement (net of
         Retained Fuel) and the quantity of gas delivered by Buyer to Seller
         under the Gas Sales Agreement. The provisions of Paragraph 6 of that
         certain Gas Nominations and Balancing Agreement entered into between
         the parties of even date herewith shall apply to the resolution of such
         differences.

         b.       Buyer agrees to initially provide a Contract Capacity of
         11,000 Mcf per Day. Buyer will use reasonable efforts to make that
         Contract Capacity available on or before April 1, 1999, but shall not
         have any liability to Seller for any failure to provide that Contract
         Capacity before that date.

         c.       From and after April 1, 1999, if Buyer, for reasons other than
         force majeure conditions, during any 3 consecutive Accounting Periods,
         fails to receive an average daily quantity of Seller's gas of at least
         95% of the lesser of (i) the then applicable Contract Capacity or (ii)
         the average quantity of gas actually made available for delivery by
         Seller (such amount being referred to as the "Required Volume), then
         Buyer shall be deemed deficient in its receipts by an amount equal to
         the difference between the Required Volume and the actual average
         receipts during those 3 consecutive Accounting Periods ("Deficient
         Quantity"). Seller shall have the right to request a permanent release
         of the Deficient Quantity by requesting such in writing to Buyer within
         15 days following the end of the applicable 3 Accounting Periods.
         Following that timely request, Buyer shall have 30 days ("Cure Period")
         in which to begin receiving the Required Volume, or if such cannot be
         remedied within the Cure Period, to nevertheless provide a reasonable
         plan to Seller specifying the actions that will be undertaken by Buyer
         to remedy the failure to purchase and receive the Required Volume. If
         Buyer does neither, then at the end of the Cure Period, the Deficient
         Quantity shall be automatically and permanently released from the terms
         of this Agreement. Upon that release the Contract Capacity shall be
         reduced by an amount equal to the Deficient Quantity and the Minimum
         Quantity under Section 2.3, b., shall also be reduced by an amount
         equal to the Deficient Quantity.

         d.       If Seller has Excess Gas at any Delivery Point, Seller may
         request Buyer, in writing, to cause the expansion of the Purchasing
         Facilities to increase the Contract Capacity to

                                       3

<PAGE>

         accommodate the delivery of that Excess Gas. Buyer will then have
         thirty (30) days after such request to determine whether it is economic
         for Buyer, in Buyer's sole judgment, to cause the expansion of the
         Purchasing Facilities under the terms of this Agreement, considering
         the amount of additional gas available from Seller and all other
         physical and economic conditions then existing. In the event that Buyer
         determines that it is economic for Buyer to cause the expansion of the
         Purchasing Facilities under the terms of this Agreement, Buyer shall
         cause the expansion of the Purchasing Facilities under the terms of
         this Agreement in a timely and diligent fashion, provided however,
         Buyer shall not be obligated to cause any expansion prior to date that
         Fort Union Gas Gathering L.L.C.'s header system is fully operational.
         Upon that expansion, the Contract Capacity shall be deemed increased by
         the amount of additional capacity provided by the expansion that is
         necessary to accommodate the Excess Gas; and, upon that expansion, the
         Excess Gas shall not be considered Excess Gas but shall be gas
         comprising the Required Volume under c., above.

         e.       In the event that Buyer determines that the additional
         capacity requested under paragraph d., above is uneconomic in Buyer's
         sole judgement, then the Excess Gas shall be permanently released from
         the terms of this Agreement upon the request of Seller.

         f.       During periods when gas production from all wells (including
         the wells on the Lands hereunder and wells of third party sellers)
         delivering to a Delivery Point exceeds the capacity available at that
         Delivery Point, Buyer shall curtail receipts of all Excess Gas, on a
         ratable basis pursuant to the-capacity committed to all sellers
         connected to the Delivery Point. Buyer shall not enter into commitments
         to provide service to producers, including Seller, in excess of the
         total capacity of the Purchasing Facilities, as it from time to time
         exists.

         g.       During periods when gas production from all wells connected to
         all Purchasing Facilities (including the Wells hereunder and wells of
         third party sellers) exceeds the capacity available to Buyer from third
         parties to receive, transport, redeliver and/or sell gas, then Buyer
         shall take gas ratably from all sources upstream of the capacity
         restriction. Gas shall be curtailed ratably from wells producing gas
         not in association with oil first and then, if capacity is still
         restricted, gas shall be curtailed ratably from wells producing gas
         together with oil ("Associated Gas"). With respect to Seller's gas that
         Buyer transports in the facilities of MIGC, Inc., Buyer agrees that
         receipts of Seller's gas shall not be curtailed due to curtailments by
         MIGC unless MIGC is then curtailing all firm transportation service.

         2.3      Price and Fees.

         a.       Buyer shall pay Seller for Seller's gas delivered to the
         Delivery Point(s) hereunder, less Retained Fuel, as defined in the Gas
         Sales Agreement. It is understood that no compensation is due from
         Buyer, or any other party, for Retained Fuel. Buyer use reasonable
         efforts to minimize fuel use and shall cause its transporters to do the
         same. Further, the gas to be resold to Seller under the Gas Sales
         Agreement, shall include any gain or loss from the Delivery Point
         through the discharge of all Purchasing Facilities where Seller's gas
         is compressed.

                                       4

<PAGE>

         b.       The Purchase Price for Seller's gas, less Retained Fuel, shall
         be equal to (i) the quantity of Seller's gas delivered to Buyer, at the
         Delivery Point, less Retained Fuel, in MMBtu, multiplied by the Index,
         less (ii) the Contract Volume (as defined below) of Seller's gas, in
         MCF, multiplied by a Fee. The Fee shall be ********* per MCF. "Index"
         shall be equal to the "INSIDE FERCs GAS MARKET REPORT, Prices of Spot
         Gas Delivered to Pipelines" index for Colorado Interstate Gas Company,
         Rocky Mountains, in the first publication of the applicable month.
         Should the above index not be published, the parties shall mutually
         agree as to an alternative publication with a price representative of
         the foregoing. "Contract Volume" shall be the greater of (i) the actual
         quantity of gas delivered; or, (ii) 95% of the Minimum Quantity; in
         MCF. During the first two Accounting Periods following the date of
         initial deliveries, the Minimum Quantity shall be five thousand (5,000)
         MCF per day. For the next thirty six (36) Accounting Periods, the
         Minimum Quantity shall be eleven thousand (11,000) MCF per day.
         Thereafter, the Minimum Quantity shall be zero. If Buyer fails to
         accept the Minimum Quantity for any reason other than due to Seller's
         inability or failure to deliver same, the Minimum Quantity for the
         Accounting Period in which the failure occurred shall be adjusted
         downward by the quantity that Buyer failed to accept. If Seller is
         unable or fails to deliver the Minimum Quantity, then, if Buyer
         purchases and receives third party gas to replace Seller's unused
         capacity, the Minimum Quantity shall be adjusted downward by the
         quantity of such third party gas.

         c.       The applicable Fee specified in 2.3, b. (ii)., above, shall be
         adjusted on an annual basis (beginning on the first day of the second
         year of the Primary Term) in proportion to the percentage change, from
         the preceding year, in the Producer Price Index for oil and gas field
         services (SIC 138) as published by the Department of Labor. The
         adjustment of the applicable portion of the fees shall be made
         effective upon each anniversary of initial deliveries hereunder and
         shall reflect the percentage change in the foregoing index as it
         existed for the immediately preceding January from the index for the
         second immediately preceding January.

         3.       TERM.

         3.1      The term of this Agreement shall extend, subject to 3.2,
below, for a period of ten (10) years from the Effective Date, ("the Primary
Term") and month-to-month thereafter until canceled by either Party upon 30
days prior written notice in advance of the expiration of the Primary Term or
of any monthly extension thereof.

         3.2      If Buyer determines, in good faith, that it is uneconomic
for Buyer to continue to receive and purchase Seller's Gas, at any Delivery
Point(s), then Buyer shall have the right to give Seller written notice of
that condition ("Uneconomic Notice"). Upon that notice:

         a.       The parties shall then attempt in good faith to negotiate
         mutually acceptable terms to provide for continued delivery of gas at
         the affected Delivery Point(s).

                                       5

<PAGE>

         b.       If the parties cannot agree on those terms within 60 days
         following the date of the Uneconomic Notice, then Buyer shall have the
         right to terminate this Agreement upon 10 days' written notice.

         c.       As used herein, "uneconomic" means circumstances under which
         the Fee attributable to the gas delivered at affected Delivery Point(s)
         is insufficient to offset Buyer's actual costs of performing under this
         Agreement and under the Gas Sales Agreement with respect to that gas.

         4.       MEASUREMENT. Measurement and determination of gas delivered,
including quantity and Gross Heating Value, shall be calculated by Buyer from
the measurements taken at the meter installed, operated and maintained by Buyer
at the Delivery Point, and from the Gross Heating Value determined by gas
chromatography, all in accordance with the recommendations set forth in the AGA
Measurement Committee Report Number 3, including any amendments or superseding
standards agreeable to the parties. The unit of measurement shall be one million
British Thermal Units (MMBtu). The measurement provisions in Exhibit C shall be
applicable to this Agreement.

         5.       QUALITY. In the event that any gas delivered by Seller
fails to meet any of the quality specifications set forth on Exhibit B, then
Buyer shall have the right to cease receiving that gas as long as that
condition exists; provided, Buyer shall also curtail all receipts of gas of
similar quality to the same extent as receipts of Seller's gas are curtailed.
Notwithstanding the foregoing, if after commingling that gas with other gas
then in the control of Buyer, the commingled stream is acceptable to all
downstream transporters receiving the commingled stream from Buyer, and as
long as the receipt of that nonconforming gas from Seller does not adversely
affect the economics of Buyer, then Buyer shall continue to receive that gas.
ln the event that Buyer ceases to receive gas as herein provided and if
Seller does not treat the gas prior to delivery hereunder to conform to the
quality specifications, then so long as that gas fails to conform to the
quality specifications Seller shall have the right to deliver the
non-conforming gas to any other party.

         6.       TAXES AND ROYALTY. Buyer shall have no responsibility for
any taxes applicable to the gas delivered hereunder, prior to its delivery to
Buyer, including all production, severance, excise, ad valorem and other
taxes of what ever nature. Buyer shall have no responsibility for any royalty
applicable to the gas delivered hereunder and Seller shall remain fully
responsible for the timely and proper payment of all royalties due on gas
delivered hereunder.

         7.       TITLE AND INDEMNIFY.

         7.1      Seller hereby warrants title to all gas sold hereunder and
that Seller has the right and full authority to sell the same to Buyer,
receive all of the proceeds from that sale, and that all gas is free from any
and all liens and adverse claims. Seller will indemnify Buyer against and
hold Buyer harmless from any and all Losses arising out of or related to
Seller s breach of the foregoing warranty. The foregoing indemnity shall
apply as to any uncertainty, dispute or claim concerning the ownership of
coalbed methane as between the coal estate and the oil and gas estate, but
any such uncertainty, dispute or claim shall not constitute -a breach of the
foregoing warranty by Seller except to the extent of any deliveries by Seller
following an adverse and final, non-appealable court order.

                                       6

<PAGE>

Buyer shall have no obligation to make payments for gas delivered hereunder
until Seller has furnished Buyer with an executed division order or title
opinion (addressed to Buyer) in form and content acceptable to Buyer indicating
that payments for all gas delivered hereunder are to be made to Seller.

         7.2      Seller shall indemnify, defend and hold Buyer harmless from
and against all Losses arising out of Seller's operation hereunder or arising
while the gas is in Seller's exclusive control and possession. Buyer shall
indemnify, defend and hold Seller harmless from and against all Losses
arising out of Buyer's operation hereunder or arising while the gas is in
Buyer's exclusive control and possession. For the purposes of this Agreement,
the gas shall be deemed to be in Seller's exclusive control and possession
until it is delivered to Buyer at the Delivery Point hereunder and after it
is delivered to the Delivery Point under the Gas Sales Agreement; and, the
gas shall be deemed to be in Buyer's exclusive control and possession after
it is delivered to Buyer at the Delivery Point hereunder and until it is
delivered to the Delivery Point under the Gas Sales Agreement.

         8.       Payment.

         8.1      Buyer shall calculate a statement showing the amount of
payment due Seller by Buyer each Accounting Period, and provide Seller with a
copy of the same, on or before the twentieth (20th) day of the month after
deliveries are made. If the actual total quantity of gas delivered and
received hereunder is not available from third party transporter(s) by the
twentieth (20th) day of the month, then Buyer shall provide the statement
based on Buyer's good-faith estimate of deliveries hereunder, which estimates
shall be corrected to reflect actual quantities on the following month's
billing or as soon thereafter as is available.

         8.2      Buyer shall pay for gas delivered and purchased hereunder
by Wire Transfer or ACH as instructed on the invoice, on or before the last
day of the month following the Accounting Period in which deliveries are made.

         8.3      In the event Buyer shall fail to pay any amount due Seller,
when the amount is due, then the overdue amount shall accrue a late payment
penalty at a rate equal to the lesser of (i) one and one half percent (1.5%)
per month, or (ii) the maximum rate permitted by applicable law. In addition
to any other rights provided under this Agreement, including those under
Section 8.4 below, and in addition to any other rights or remedies Seller may
have at law or at equity, if Buyer fails to pay amounts due Seller when due,
then Seller may suspend further delivery of gas until that amount is paid.

         8.4      Prior to the commencement of deliveries and sales of
natural gas under this Agreement, and from time to time thereafter as
requested by Seller, Buyer shall furnish Seller with credit information as
may be reasonably required to determine Buyer's creditworthiness. If during
the term of this Agreement the financial responsibility of Buyer, based upon
credit information supplied to Seller, or based upon Buyer's performance or
lack of performance hereunder, or based upon any other reasonable grounds
which would give rise to insecurity with respect to the performance of Buyer,
then Seller may demand adequate assurance of due performance from Buyer in
form and content reasonably acceptable to Seller, and until Seller receives
that assurance may, as

                                       7

<PAGE>

a non-exclusive remedy, suspend Seller's deliveries of gas hereunder. If
adequate assurance of due performance is not received by Seller within five (5)
days of its demand, then Seller may, in addition to any other rights, claim
repudiation of this Agreement by Buyer. The parties expressly waive any longer
time periods in which to provide adequate assurances as may be contained in
applicable laws or statutes.

         9.       SUCCESSION AND ASSIGNMENT. This Agreement may not be
assigned by either party without the consent of the other party, which
consent shall not be unreasonably withheld. This Agreement, and each of its
terms and conditions, shall bind and inure to the benefit of the Parties
hereto and to their respective successors and assignees. However, any such
assignment must be in writing and shall not be binding on the other Party
unless and until a copy is provided to the other party, and further, shall
not be binding upon Buyer until Buyer has been furnished with appropriate
transfer orders or letters-in-lieu of transfer or division orders.

         10.      FORCE MAJEURE

         10.1     Except for payment due hereunder, neither Party shall be
liable to the other for failure or delay in making or accepting deliveries or
performing other obligations hereunder to the extent that the failure or
delay may be due to Force Majeure conditions.

         10.2     The party claiming Force Majeure must give notice thereof
to the other Party as soon as is reasonably practicable, and shall remedy the
Force Majeure with reasonable diligence.

         10.3     If either party is prevented from performing hereunder to
the full extent of its obligations by Force Majeure conditions for more than
30 consecutive days or more than 90 days in any 12-month period, the other
party shall have the right to terminate this Agreement by providing written
notice to the other party.

         10.4     During any period of Force Majeure, Buyer shall be
authorized to purchase and receive third party gas to replace Seller's unused
Contract Capacity and Seller shall be authorized to sell and deliver its gas
subject to Force Majeure to any third party purchaser.

         11.      REGULATORY BODIES. In the event any regulatory body asserts
jurisdiction over the sale of natural gas hereunder, either party may
terminate this Agreement upon 10 days advance written notice unless, before
that time, the parties are able to agree upon modifications to this Agreement
that restore the economic benefit to the party deprived by the assertion of
that jurisdiction.

         12.      CONFIDENTIALITY. The terms of this Agreement, including,
but not limited to, the price paid for gas, the volumes of gas purchased or
sold, and all other material terms of this Agreement shall be kept
confidential by the Parties hereto, except to the extent that information (i)
is disclosed to the direct consultants (attorneys, accountants, bankers)
working interest and royalty owners whose pro rata share of production is
marketed by a Party, or to prospective purchasers after they have agreed to
be bound by this confidentiality provision, (ii) is disclosed to a downstream
transporter under such transporter's tariff requirements for the purpose of
arranging transportation, or (iii) is disclosed as required by applicable
law, regulation, court order or subpoena.

                             QUALITY SPECIFICATIONS




Gas delivered by Seller hereunder to Buyer shall:

         (a)    be reasonably free from dust, gum, gum-forming
                constituents, condensate, free water, diluents, and other
                liquids and solids which may become separated from the
                gas;

         (b)    contain not more than ten (10) ppm (parts per million)
                oxygen by volume (and Seller shall make every effort to
                keep gas free from oxygen);

                contain not more than one-fourth (1/4) grain of hydrogen sulfide
                per one hundred (100) Cubic Feet of Gas;

         (d)    contain not more than twenty (20) grains of total sulphur,
                including sulphur in hydrogen sulfide and mercaptan, per one
                hundred (100) Cubic Feet of Gas;

         (e)    contain not more than three percent (3%) carbon dioxide, by
                volume;

         (f)    have a temperature less than or equal to one hundred (100)
                degrees Fahrenheit;

                                   MEASUREMENT

                  Seller, or Seller's authorized agent, may, at its option and
expense, install and operate measuring equipment to check Buyer's measuring
equipment provided the installation of the check measuring equipment in no way
interferes with the operation of Buyer's measuring equipment. Any check
measuring equipment installed by Seller shall be located upstream of Buyer's
measuring equipment.

                  All gas volume measurements shall be based on an assumed
atmospheric pressure of twelve-and-seven-tenths (12.7) psia, regardless of
actual atmospheric pressure at which the gas is measured. Gas volume
calculations will be made in accordance with ANSI/API 2530, as amended from time
to time.

                  Buyer shall test the accuracy of its measuring equipment at
least semiannually, or as required by regulatory agencies having jurisdiction.
Buyer shall give Seller, and regulatory agencies having jurisdiction and
entitled to notice, reasonable prior notice of any test or adjustment of any
measuring equipment. Additional test(s) shall be promptly performed upon
notification by either party to the other and the cost of any such additional
tests shall be borne by the requesting party.

                  Upon test, any measuring equipment found to be in error shall
be immediately corrected. If, upon test, the error does not exceed two percent
(2%), the equipment shall be considered correct in computing deliveries
hereunder. If, upon test, the error exceeds two percent (2%), then any preceding
recordings of such equipment shall be corrected to zero error for any period
which is known definitely or agreed upon. If the period is not known definitely
or agreed upon, such correction shall be for a period extending back one-half
(1/2) of the time elapsed since the last test. Correction of deliveries shall be
calculated by the first of the following methods which is feasible: (i) by
correcting the error if the percentage of error is ascertainable by calibration,
test, or mathematical calculations; or (ii) by using the registration of any
check meter or meters installed and accurately registering; or (iii) by
estimating the quantity of delivery by deliveries during periods of similar
conditions when the meter was registering accurately.

                  The composition and BTU content of any gas stream required to
be measured hereunder shall be determined by Buyer semi-annually, or more often
if deemed necessary by Buyer, at the point where the measurement equipment is
located, by chromatographic analysis, or by other industry standard method
mutually acceptable to the parties.

                  Buyer shall at its expense install, operate, and maintain
mutually acceptable "ELECTRONIC FLOW MEASUREMENT" (EFM) and communication
equipment required for data acquisition, at each Delivery Point, in compliance
with API Chapter 21, Section 1, as amended from time to time. Seller and Buyer
shall be jointly responsible for obtaining any necessary approvals and giving
any required notices to the appropriate governmental agencies, including the
Bureau of Land Management, that EFM equipment will be utilized for custody
transfer measurement from Seller to Buyer. Should Seller and Buyer be unable to
obtain any of those requisite approvals, Buyer shall

                                       13

<PAGE>

remove any EFM equipment for which the approval was not obtained and replace
that EFM equipment with acceptable custody transfer measurement equipment. Buyer

                          GENERAL TERMS AND CONDITIONS
                          BASE CONTRACT FOR SHORT-TERM
                        SALE AND PURCHASE OF NATURAL GAS

SECTION 1.   PURPOSE AND PROCEDURES

1.1 These General Terms and Conditions are intended to facilitate purchase and
sale transactions of Gas on a Firm or Interruptible basis. "Buyer" refers to the
party receiving Gas and "Seller" refers to the party delivering Gas.


THE PARTIES HAVE SELECTED EITHER THE "ORAL" VERSION OR THE "WRITTEN" VERSION OF
TRANSACTION PROCEDURES AS INDICATED ON THE BASE CONTRACT.
- -------------------------------------------------------------------------------
ORAL TRANSACTION PROCEDURE:
- -------------------------------------------------------------------------------
1.2 The parties will use the following Transaction Confirmation procedure. Any
Gas purchase and sale transaction may be effectuated in an EDI transmission or
telephone conversation with the offer and acceptance constituting the agreement
of the parties. The parties shall be legally bound from the time they so agree
to transaction terms and may each rely thereon. Any such transaction shall be
considered a "writing" and to have been "signed". Notwithstanding the foregoing
sentence, the parties agree that Confirming Party shall, and the other party
may, confirm a telephonic transaction by sending the other party a Transaction
Confirmation by facsimile, EDI or mutually agreeable electronic means.
Confirming Party adopts its confirming letterhead, or the like, as its signature
on any Transaction Confirmation as the identification and authentication of
Confirming Party.
- -------------------------------------------------------------------------------
WRITTEN TRANSACTION PROCEDURE:
- -------------------------------------------------------------------------------
1.2    The parties will use the following Transaction Confirmation procedure.
Should the parties come to an agreement regarding a Gas purchase and sale
transaction for a particular Delivery Period, the Confirming Party shall, and
the other party may, record that agreement on a Transaction Confirmation and
communicate such Transaction Confirmation by facsimile, EDI or mutually
agreeable electronic means, to the other party by the close of the Business
Day following the date of agreement. The parties acknowledge that their
agreement will not be binding until the exchange of non-conflicting
Transaction Confirmation or the passage of the Confirm Deadline without
objection from the receiving party, as provided in Section 1.3.

1.3    If a sending party's Transaction Confirmation is materially different
from the receiving party's understanding of the agreement referred to in
Section 1.2, such receiving party shall notify the sending party via
facsimile by the Confirm Deadline, unless such receiving party has previously
sent a Transaction Confirmation to the sending party. The failure of the
receiving party to so notify the sending party in writing by the Confirm
Deadline constitutes the receiving party's agreement to the terms of the
transaction described in the sending party's Transaction Confirmation. If
there are any material differences between timely sent Transaction
Confirmations governing the same transaction, then neither Transaction
Confirmation shall be binding until or unless such differences are resolved
including the use of any evidence that clearly resolves the differences in
the Transaction Confirmations. The entire agreement between the parties shall
be those provisions contained in both the Base Contract and any effective
Transaction Confirmation. In the event of a conflict among the terms of (i) a
Transaction Confirmation, (ii) the Base Contract, and (iii) these General
Terms and Conditions, the terms of the documents shall govern in the priority
listed in this sentence.

to the difference between the Contract Quantity and the actual quantity
delivered by Seller and received by Buyer for such Day(s), multiplied by the

       EXCEPT AS OTHERWISE SPECIFICALLY PROVIDED HEREIN, IN NO EVENT WILL
EITHER PARTY BE LIABLE UNDER THIS CONTRACT, WHETHER IN CONTRACT, IN TORT

SECTION 4.   TRANSPORTATION, NOMINATIONS AND IMBALANCES

4.1    Seller shall have the sole responsibility for transporting the Gas to
the Delivery Point(s) and for delivering such Gas at a pressure sufficient to
effect such delivery but not to exceed the maximum operating pressure of the
Receiving Transporter. Buyer shall have the sole responsibility for
transporting the Gas from the Delivery Point(s).

4.2    The parties shall coordinate their nomination activities giving
sufficient time to meet the deadlines of the affected Transporter(s). Each
party shall give the other party timely prior notice, sufficient to meet the
requirements of all Transporter(s) involved in the transaction, of the
quantities of Gas to be delivered and purchased each Day. Should either party
become aware that actual deliveries at the Delivery Point(s) are greater or
lesser than the Scheduled Gas, such party shall promptly notify the other
party.

4.3    The parties shall use commercially reasonable efforts to avoid
imposition of any Imbalance Charges. If Buyer or Seller receives an invoice
from a Transporter that includes Imbalance Charges, the parties shall
determine the validity as well as the cause of such Imbalance Charges. If the
Imbalance Charges were incurred as a result of Buyer's actions

                                       -5-
<PAGE>


or inactions (which shall include, but shall not be limited to, Buyer's
failure to accept quantities of Gas equal to the Scheduled Gas), then Buyer
shall pay for such Imbalance Charges, or reimburse Seller for such Imbalance
Charges paid by Seller to the Transporter. If the Imbalance Charges were
incurred as a result of Seller's actions or inactions (which shall include,
but not be limited to, Seller's failure to deliver quantities of Gas equal to
the Scheduled Gas), then Seller shall pay for such Imbalance Charges, or
reimburse Buyer for such Imbalance Charges paid by Buyer to the Transporter.

SECTION 5.  QUALITY AND MEASUREMENT

All Gas delivered by Seller shall meet the quality and heat content
requirements of the Receiving Transporter. The unit of quantity measurement
for purposes of this Contract shall be one MMBtu dry. Measure of Gas
quantities hereunder shall be in accordance with the established procedures
of the Receiving Transporter.

SECTION 6.   TAXES

- ------------------------------------------------------------------------------
THE PARTIES HAVE SELECTED EITHER THE "BUYER PAYS AT AND AFTER DELIVERY POINT"
VERSION OR THE "SELLER PAYS BEFORE AND AT DELIVERY POINT" VERSION AS INDICATED
ON THE BASE CONTRACT.
- ------------------------------------------------------------------------------
BUYER PAYS AT AND AFTER DELIVERY POINT:
- ------------------------------------------------------------------------------
Seller shall pay or cause to be paid all taxes, fees, levies, penalties,
licenses or charges imposed by any government authority ("Taxes") on or with
respect to the Gas prior to the Delivery Point(s). Buyer shall pay or cause
to be paid all Taxes on or with respect to the Gas at the Delivery Point(s)
and all Taxes after the Delivery Point(s). If a party is required to remit or
pay Taxes that are the other party's responsibility hereunder, the party
responsible for such Taxes shall promptly reimburse the other party for such
Taxes. Any party entitled to an exemption from any such Taxes or charges
shall furnish the other party any necessary documentation thereof.
- ------------------------------------------------------------------------------
SELLER PAYS BEFORE AND AT DELIVERY POINT:
- ------------------------------------------------------------------------------
Seller shall pay or cause to be paid all taxes, fees, levies, penalties,
licenses or charges imposed by any government authority ("Taxes") on or with
respect to the Gas prior to the Delivery Point(s) and all Taxes at the
Delivery Point(s). Buyer shall pay or cause to be paid all Taxes on or with
respect to the Gas after the Delivery Point(s). If a party is required to
remit or pay Taxes which are the other party's responsibility hereunder, the
party responsible for such Taxes shall promptly reimburse the other party for
such Taxes. Any party entitled to an exemption from any such Taxes or charges
shall furnish the other party any necessary documentation thereof.
- ------------------------------------------------------------------------------

SECTION 7.   BILLING, PAYMENT AND AUDIT

7.1    Seller shall invoice Buyer for Gas delivered and received in the
preceding Month and for any other applicable charges, providing supporting
documentation acceptable in industry practice to support the amount charged.
If the actual quantity delivered is not known by the billing date, billing
will be prepared based on the quantity of Scheduled Gas. The invoiced
quantity will then be adjusted to the actual quantity on the following
Month's billing or as soon thereafter as actual delivery information is
available.

7.2    Buyer shall remit the amount due in the manner specified in the Base
Contract, in immediately available funds, on or before the later of the
Payment Date or 10 days after receipt of the invoice by Buyer; provided that
if the Payment Date is not a Business Day, payment is due on the next
Business Day following that date. If Buyer fails to remit the full amount
payable by it when due, interest on the unpaid portion shall accrue at a rate
equal to the lower of (i) the then-effective prime rate of interest
published under "Money Rates" by The Wall Street Journal, plus two percent
per annum from the date due until the date of payment; or (ii) the maximum
applicable lawful interest rate. If Buyer, in good faith, disputes the amount
of any such statement or any part thereof, Buyer will pay to Seller such
amount as it concedes to be correct; provided, however, if Buyer disputes the
amount due, Buyer must provide supporting documentation acceptable in
industry practice to support the amount paid or disputed.

<PAGE>


7.3    In the event any payments are due Buyer hereunder, payment to Buyer
shall be made in accordance with Section 7.2 above.

7.4    A party shall have the right, at its own expense, upon reasonable
notice and at reasonable times, to examine the books and records of the other
party only to the extent reasonably necessary to verify the accuracy of any
statement, charge, payment, or computation made under the Contract. This
examination right shall not be available with respect to proprietary
information not directly relevant to transactions under this Contract. All
invoices and billings shall be conclusively presumed final and accurate
unless objected to in writing, with adequate explanation and/or
documentation, within two years after the Month of Gas delivery. All
retroactive adjustments under Section 7 shall be paid in full by the party

prepayment, a security interest in an asset acceptable to the demanding party

in the commencement of a proceeding or cause under any bankruptcy or similar

11.1   Except with regard to a party's obligation to make payment due under

liable to the other for failure to perform a Firm obligation, to the extent
such failure was caused by Force Majeure. The term "Force Majeure" as
employed herein means any cause not reasonably within the control of the
party claiming suspension, as further defined in Section 11.2.

11.2   Force Majeure shall include but not be limited to the following: (i)
physical events such as acts of God, landslides, lightning, earthquakes,
fires, storms or storm warnings, such as hurricanes, which result in
evacuation of the affected area, floods, washouts, explosions, breakage or
accident or necessity of repairs to machinery or equipment or lines of pipe;
(ii) weather-related events affecting an entire geographic region, such as
low temperatures which cause freezing or failure of wells or lines of pipe;
(iii) interruption of firm transportation and/or storage by Transporters;
(iv) acts of others such as strikes, lockouts or other industrial
disturbances, riots, sabotage, insurrections or wars; and (v) governmental
actions such as necessity for compliance with any court order, law, statute,
ordinance, or regulation promulgated by a governmental authority having
jurisdiction. Seller and Buyer shall make reasonable efforts to avoid the
adverse impacts of a Force Majeure and to resolve the event or occurrence
once it has occurred in order to resume performance.

11.3   Neither party shall be entitled to the benefit of the provisions of
Force Majeure to the extent performance is affected by any or all of the
following circumstances: (i) the curtailment of interruptible or secondary
firm transportation unless primary, in-path, firm transportation is also
curtailed; (ii) the party claiming excuse failed to remedy the condition and
to resume the performance of such covenants or obligations with reasonable
dispatch; or (iii) economic hardship. The party claiming Force Majeure shall
not be excused from its responsibility for Imbalance Charges.

11.4   Notwithstanding anything to the contrary herein, the parties agree
that the settlement of strikes, lockouts or other industrial disturbances
shall be entirely within the sole discretion of the party experiencing such
disturbance.

11.5   The party whose performance is prevented by Force Majeure must provide
notice to the other party. Initial notice may be given orally; however,
written notification with reasonably full particulars of the event or
occurrence is required as soon as reasonably possible. Upon providing written
notification of Force Majeure to the other party, the affected party will be
relieved of its obligation to make or accept delivery of Gas as applicable to
the extent and for the duration of Force Majeure, and neither party shall be
deemed to have failed in such obligations to the other during such occurrence
or event.

be paid by Seller, and that Seller has good right and lawful authority to sell
the same. Seller shall indemnity and save Buyer harmless from any and all suits,
claims, liens, and encumbrances of whatever nature relating to such gas,
payments for such gas, or the title thereto and shall reimburse Buyer for any
and all costs incurred by Buyer (including, without limitation, all attorney's
fees) in defense of suit or claim.

         2. Title to, and risk of loss for, all natural gas delivered hereunder
shall pass from Seller to Buyer at the Point of Receipt.

                           ARTICLE 10 - FORCE MAJEURE

         1. Neither Seller nor Buyer shall be liable in damages to the other for
any act, omission or circumstances occasioned by or in consequence of, any acts
of God, strikes, lockouts or other


                                     -7-

industrial disturbances, acts of the public enemy, wars, blockades,
insurrections, riots, epidemics, fires, arrests and restraints of rulers and
peoples, civil disturbances, explosions, breakage or accident to machinery,
vessels or lines of pipe, repair or alterations of machinery, vessels or lines
of pipe, acts of third party transporters including Williston Basin, freezing or
failure of wells or lines of pipe, the binding of any court or governmental
authority, and any other cause, whether of the kind herein enumerated or
otherwise, not within the control of the one claiming suspension and which, by
the exercise of due diligence, it is unable to prevent or overcome.

         2. Such causes or contingencies affecting performance shall not relieve
Seller or Buyer of liability in the event of its concurring negligence or in the
event of failure of either to use due diligence to remedy the situation and
remove the cause in an adequate manner and with all reasonable dispatch, nor
shall such causes or contingencies relieve either from its obligations to make
payments of amounts then due hereunder.

         3. In order to suspend by reason of Force Majeure, the party claiming
must give notice in writing or by telecopy, or orally and confirmed in writing
or by telecopy to the other party as soon as possible after the occurrence of
the cause relied on, and such cause shall be remedied with all reasonable
dispatch. No party shall be required against its will to adjust or settle any
labor disputes.

         4. In the event of a Force Majeure incident which would only allow a
partial delivery of Seller's total deliveries, Seller shall deliver to Buyer a
quantity of gas which represents Buyer's pro-ratable share of Seller's total
available delivery quantity which is proportionate to Seller's obligation to
Buyer compared to the quantity obligation to Seller's other firm gas purchase
customers.

         5. In the event of Force Majeure preventing total delivery by Seller of
the Nominated Quantity at Transporter's Point of Receipt, Buyer and Seller shall
be relieved of their obligations under this Agreement until such cause of Force
Majeure is remedied.

         6. In the event of Force Majeure, both parties agree to exort their
best efforts to effectuate performance of this Agreement.
