(1)  BASIS OF PRESENTATION

     The accompanying financial statements are for CEC Resources Ltd.
("Resources" or "Company"). Resources is an independent oil and gas company and
was incorporated on May 31, 1955 under the Business Corporations Act (Alberta )
in Canada and was acquired by the former parent of Columbus Energy Corporation
("Columbus") in 1969 and by Columbus on July 31, 1984. It remained a wholly
owned subsidiary of Columbus until spun-off from Columbus by a rights offering
in February 1995.

     These financial statements are prepared in accordance with Canadian
generally accepted accounting principles ("GAAP") and require the use of
management's estimates. These statements contain all adjustments (consisting
only of normal recurring accruals) which, in the opinion of management, are
necessary to present fairly the financial position of the Company as of
August 31, 1999 and November 30, 1998, and the results of its operations and of
its cash flows for the periods presented. The results of operations for interim
periods are not necessarily indicative of results to be expected for the full
year.

Currency

     The amounts in these financial statements and notes thereto are in Canadian
dollars, unless otherwise stated.

Cash Equivalents

     For purposes of the statements of cash flow, the Company considers all
temporary investments to be cash equivalents. Results of hedging activities,
when employed, are included in cash flow from operations in the statements of
cash flow.

Oil and Gas Properties

     The Company follows the full cost method of accounting whereby all costs
associated with the acquisition of, exploration for, and the development of oil
and gas reserves are capitalized. Such costs include land acquisition costs,
geological and geophysical expenditures, drilling costs of productive and non-
productive wells and tangible production equipment. General and administrative
expenses are capitalized to the extent such costs are directly associated with
acquisition, exploration and development of oil and gas properties. Proceeds
from the sale of petroleum and natural gas properties reduce capitalized costs
without recognition of a gain or loss unless such a sale would significantly
alter the rate of depletion and depreciation.

     Capitalized costs, including tangible production equipment, are depleted
using the unit of production method based on proved reserves of oil and gas,
before royalties, as estimated by independent engineers. For purposes of the
calculation, oil and gas reserves are converted to a common unit of measure on
the basis of six thousand cubic feet of gas

                                       7
<PAGE>

to one barrel of oil. Depreciation of the natural gas liquids processing plant
and other property and equipment are calculated using the straight line method
over their estimated useful lives.

     In applying the full cost method, the Company performs a ceiling test which
restricts the net capitalized costs from exceeding an amount equal to the
estimated undiscounted value of future net revenues from proven oil and gas
reserves, based on current prices and costs, after deducting estimated future
operating costs, development costs, general and administrative expenses and
income tax expense.

     Estimated future site abandonment and restoration costs are provided using
the unit of production method over the life of proven reserves with the current
year provision included in depreciation, depletion and amortization expense.
Site abandonment and restoration expenditures incurred are recorded as a
reduction of the accumulated accrual.

Field Services Business Segment

     The Company receives field service revenue generated by its share of
natural gas processing fees at the Carbon gas plant. The portion of the plant
processing fee revenue attributable to Resources own gas volumes processed by
the plant is not reported as field service revenue, but instead offsets an
identical amount otherwise chargeable to lease operating expenses. The Carbon
plant also processes natural gas belonging to unrelated plant non-owners which
represents the majority of Resources field services revenues.

     Resources also derives less significant revenues and net cash flow from
other gathering and compression facilities in which it has ownership. Amounts
applicable to Resources' own gas production volumes have likewise been
eliminated from both revenues and expenses from these operations.

Income Taxes

     The liability method is used in measuring income taxes based on temporary
differences including timing differences and other differences between the tax
basis of an asset or liability and its carrying amount in the financial
statements. The method uses the tax rate and the tax law expected to apply to
taxable income in the periods in which the future income tax asset or liability
is expected to be realized. The Company is subject to tax under applicable
Canadian tax law.

Earnings Per Share

     Basic earnings per share are calculated using the weighted average number
of shares of common stock outstanding during the period. Fully diluted earnings
per share are calculated assuming the exercise of outstanding dilutive options.

(2)  STATEMENTS OF CASH FLOW

     The Company elected for 1998 to adopt Canadian Institute of Chartered
Accountants (CICA) 1540, Cash Flow Statements, which require a business
enterprise to provide a statement of cash flow in place of a statement of
changes in financial position. Application of CICA 1540 is required for fiscal
years beginning on or after August 1, 1998. Cash flow information for prior
years is restated to conform to the requirements of CICA 1540 as follows:

     For Canadian income tax purposes Resources has tax pools available at
August 31, 1999 to reduce future taxable income. These pools include oil and gas
property expenses of $4,235,000, development and exploration expenses of
$1,042,000, earned depletion base of $1,170,000 and undepreciated capital costs
of $2,465,000. The tax attributes of carryforward pools are included to
determine the temporary differences shown as deferred tax liabilities. These
attributes generally do not expire.


(4)  RELATED PARTY TRANSACTIONS

     Resources incurred certain direct and indirect general and administrative
costs for services provided by its former Parent in lieu of expanding the number
of its own full-

                                       10

time employees. These costs were primarily for labor, related benefits and other
overhead costs as provided by an agreement between the parties. These costs were
$54,000 and $271,000 for the first nine months of 1999 and 1998, respectively.
Effective March 31, 1999, this management agreement was terminated.


(5)  COMMITMENTS

     The majority of the Company's natural gas is contracted to gas marketing
companies on a deliverability basis and sold at published index prices less
applicable transportation and marketing charges. The Company has temporarily
assigned its firm transportation agreements through October, 1999 and has
retained the option to obtain additional firm transportation service. At
August 31, 1999, the Company had seven forward priced hedge contracts. These
contracts allow the Company to receive fixed prices for a percentage of its
production. The terms of these transactions are as follows:

</TABLE>

     The unrecognized loss on these contracts totaled $806,000 based on
August 31, 1999 market values.

     The Company estimates that future costs of site abandonment and restoration
of well sites, gas processing plants and other facilities will be $434,362 as of
August 31, 1999 in addition to $221,000 already accrued as a liability. The
estimated costs are being recognized on a unit-of-production basis over the life
of the properties.


(6)  ACQUISITION OF OIL AND GAS PROPERTIES

     Between December 1998 and April 1999, Resources purchased producing oil and
gas properties and natural gas gathering and compression facilities in Alberta,
Canada. These acquisitions were accounted for as a purchase and considered
"material" by management for purposes of pro forma disclosure. The following pro
forma statement presents incremental results of operations for the current year
and for the corresponding period of the preceding year as though the
acquisitions had occurred at the beginning of

the periods being reported on. Revenues and expenses subsequent to the purchase
dates have been included in 1999 operating results and are not included in the
incremental results.

     The incremental pro forma results below are not indicative of the results
that would have occurred if the acquisitions had been in effect for the entire

(7)  GENERALLY ACCEPTED ACCOUNTING PRINCIPLES IN CANADA AND THE UNITED STATES

     The financial statements have been prepared in accordance with Canadian
GAAP and differ in certain respects from financial statements which the Company
would have made had its financial statements been prepared in accordance with
United States GAAP. Differences between the two methods which affect these
financial statements are:

     (a)  Under U.S. GAAP, cash (and cash equivalents) includes bank deposits,
          money market instruments, and commercial paper with original
          maturities of three months or less. Canadian GAAP permits the
          inclusion in cash of temporary investments with maturities greater
          than 90 days. The differences in measurement had no impact on
          classifications in the balance sheets.

     (b)  Basic earnings per share using U.S. GAAP is the same as basic earnings
          per share using Canadian GAAP. Under U.S. GAAP, fully diluted
          earnings per share are reported using the "treasury stock
          method." Under Canadian GAAP, fully diluted earnings per share assumes
          that cash proceeds from the deemed exercise of stock options are
          invested by the

                                       12
<PAGE>

          Company in such a way as to earn a reasonable return. The number of
          shares used in the calculation is the same for both methods.

     (c)  Under U.S. GAAP, the full cost accounting method requires that
          capitalized costs less related accumulated depletion and deferred
          income taxes may not exceed the sum of (1) the present value
          (discounted at 10%) of future net revenues from estimated production
          of proved oil and gas reserves; plus (2) the cost of properties not
          being amortized, if any, plus (3) the lower of cost or estimated fair
          value of unproved properties included in the costs being amortized if
          any, less (4) income tax effects related to differences in the book
          and tax basis of oil and gas properties. Using U.S. GAAP, there would
          not have been an impairment to the full cost pool.

Item 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

     The discussion below summarizes the Company's financial condition and
results of operations and should be read in conjunction with the financial

Results of Operations

Three months ended August 31, 1999 compared to three months ended August 31,
l998.

     Total revenues for the third quarter of 1999 were $1,307,000, a 77%
increase from the prior year period amount of $737,000. The increase was due
primarily to higher natural gas production, including production resulting from
the Company's Acquisitions, and higher natural gas, oil and plant liquid prices.
Net income in the third quarter of 1999 was $36,000 compared to $54,000 in the
third quarter of 1998. The decrease was primarily due to increased general and
administrative expenses, increased depletion, depreciation and amortization
expenses, offset by higher natural gas, oil and plant liquid revenues, lease
operating cost efficiencies and a deferred tax benefit.

     The following table show comparative revenue, sales volumes, average prices
and percentage changes between periods, for natural gas, oil and plant liquids
for the third quarters of 1999 and 1998:

     Average daily oil and plant liquid production in the third quarter of 1999
were 64 and 90 barrels, respectively. Average daily gas production for the third
quarter of 1999 was 4,471 mcf. This is an increase of 42% on a barrel of oil
equivalent ("boe") basis compared to the same period in 1998.

     The Company's continued success with the exploitation of properties
acquired during 1999 and current development activity has resulted in
increasing production for three successive quarters. Exploration activities are
expected to continue for the balance of 1999.

     Average oil prices increased 52% from $16.96 per barrel in the third
quarter of 1998 to $25.78 in 1999. Average plant liquid prices increased 60%
from $11.75 in the third quarter of 1998 to $18.84 in 1999. Average natural gas
prices increased 35% from $1.98 per mcf for the third quarter of 1998 to $2.67
per mcf in 1999.

     Royalty expense consists primarily of Crown Royalties as well as smaller
amounts of freehold and gross overriding royalties. The Company is eligible for
the Alberta Royalty Tax Credit ("ARTC") which varies inversely with prevailing
prices for oil and gas sales in Alberta. For the third quarter of 1999 the net
Crown Royalty rate was 6% compared to 5% in 1998.

     Lease operating expenses totaled $231,000 or $2.79 per boe for the third
quarter of 1999 compared to $187,000 or $3.20 per boe in the prior year period.
This reduction in per boe expense is due to efficiencies realized from operating
the Company's East Carbon properties and the fact that lease operating
expenses for 1998 were higher due to well workovers at the Company's Hoffer
properties.

     Field netbacks commonly reported by Canadian energy companies equate to oil
and gas sales less royalties and lease operating expenses. Resources' average
field netback increased significantly for the third quarter of 1999 to $12.78
per boe compared to $8.29 for the third quarter of 1998 primarily due to the
positive revenue and lease operating expense variances previously discussed.

     Resources has always followed the U.S. practice of converting its natural
gas to boe based on the heating value ratio of six mcf of natural gas to one
barrel of oil. A ratio of 10:1 which historically has more closely approximated
price ratios, is used by nearly all Canadian public companies.

     If natural gas had been converted to boe using the Canadian practice of a
10:1 ratio, then reported field netbacks would have been $19.12 and $12.01 per
boe for the third quarter of 1999 and 1998, respectively.

     General and administrative expenses, net of third party reimbursements, for
the third quarter of 1999 totaled $466,000, a $210,000 or 82% increase for the
same period of

                                       15
<PAGE>

1998. The increase in general and administrative expense was primarily due to
the hiring of full time employees

     Interest and other expenses were $77,000 in the third quarter of 1999, a
$107,000 increase from the prior year period. Interest expense increased as a
result of incurring long-term debt in 1999 to partially fund acquisitions. See
"Acquisitions" and "Liquidity and Capital Resources". The Company's average
borrowing rate for the third quarter of 1999 was 7.0%.

     Depletion, depreciation and amortization expense for the third quarter of
1999 totaled $618,000, an increase of $406,000 or 191% from the 1998 level.
Depletion expense increased primarily due to increased gas sales and a
downward adjustment to CEC's 1998 year end developed non-producing and proved
undeveloped natural gas reserves that resulted in an increased depletion rate
per boe in 1999 compared to 1998.

Nine months ended August 31, 1999 compared to nine months ended August 31, 1998.

     Revenues for the nine months ended August 31, 1999 totaled $3,463,000
million, a 46% increase from the prior year period. The increase was due
primarily to increased natural gas and plant liquid production, including
production resulting from the Company's acquisitions and higher natural gas, oil
and plant liquid prices. The net loss in the first nine months of 1999 was
$188,000 compared to net income of $268,000 in the first nine months of 1998.
The decrease was primarily due to increased general and administrative expenses,
increased depletion, depreciation and amortization expenses partially offset by
higher oil, natural gas and plant liquid revenues.

     The following table shows comparative revenue, sales volume, average prices
and percentage changes between periods, for natural gas, oil, and plant liquids
for the first nine months of 1999.

     Average daily oil and plant liquid production for the first nine months of
1999 were 67 and 87 barrels, respectively. Average daily gas production for the
first nine months of 1999 was 4,069 mcf. This is an increase of 21% on a boe
equivalent basis compared to the same period in 1998.

     The Company's continued success with the exploitation of properties
acquired during 1999 and current development activity has resulted in
increasing production for three successive quarters. Exploration activities are
expected to continue for the balance of 1999.

     Average oil prices increased 13% from $18.51 per barrel in the first 9
months of 1998 to $20.91 in 1999. Average plant liquids prices increased 4% from
$14.69 for the first nine months of 1998 to $15.34 in 1999. Average natural gas
prices increased 36% from $1.93 per mcf for the first nine months of 1998 to
$2.63 in 1999.

     Royalty expense consists primarily of Crown Royalties as well as smaller

oil and gas sales in Alberta. For the first nine months of 1999 and 1998 the net
Crown Royalty rate was 6%.

     Lease operating expenses totaled $585,000 or $2.57 per boe for the first
nine months of 1999 compared to $563,000 or $2.99 per boe in the prior year
period. This reduction in per boe expense is due to efficiencies realized from
operating the Company's East Carbon properties and the fact that lease operating
expenses for 1998 were higher due to well workovers at the Company's Hoffer
properties.

     Field netbacks commonly reported by Canadian energy companies equate to oil
and gas sales less royalties and lease operating expenses. Resources' average
field netback increased significantly for the first nine months of 1999 to
$12.28 per boe compared to $8.50 per boe for the first nine months of 1998
primarily due to the positive revenue and lease operating expense variances
previously discussed.

     Resources has always followed the U.S. practice of converting its natural
gas to boe based on the heating value ratio of six mcf of natural gas to one
barrel of oil. A ratio of 10:1 which historically has more closely approximated

     If natural gas volume had been converted to boe using the Canadian practice
of a 10:1 ratio, then reported field netbacks would have been $18.22 and $12.40
per boe for the first nine months of 1999 and 1998, respectively.

     General and administrative expenses, net of third party reimbursements, for
the first nine months of 1999 totaled $1,522,000, a $908,000 or 148% increase
from the same period in 1998. The increase in general and administrative expense
was primarily due to the hiring of full time employees, partially offset by a
reduction in charges for management services provided by Columbus under a
management contract which was terminated March 31, l999.

     Interest and other expenses increased to $136,000 for the first nine months
of 1999, a $159,000 increase from the prior year period. Interest expense
increased as a result of incurring long-term debt in 1999 to partially fund
acquisitions. See "Acquisitions" and "Liquidity and Capital Resources". The
Company's average interest rate for the first nine months of 1999 was 7.25%.

     Depletion, depreciation and amortization expense for the nine month period
ended August 31, l999 totaled $1,597,000, a increase of $911,000 or 133% from
the 1998 level. Depletion expense increased primarily due to increased gas sales
and a downward adjustment to CEC's 1998 year end developed non-producing and
proved undeveloped natural gas reserves that resulted in an increased depletion
rate boe in 1999 compared to 1998. For the first nine months of 1999 the
depletion rate was $6.29 per boe, compared to $3.20 per boe for the same period
in 1998.

Acquisitions

     In December 1998 the Company acquired for $2.3 million working interests in
16 natural gas wells, associated natural gas gathering and compression
facilities and undeveloped lands in the East Carbon Field (Wayne-Rosedale),
located in Alberta, Canada from Neutrino Resources, Ltd. The acquisition was
funded with cash and bank financing. The acquisition increased the Company's
working interest ownership in the East Carbon Field from 33-1/3% to 64%. The
Company estimates that as of November 30, 1998, the remaining proved reserves
before royalty of the acquired properties are approximately 51,000 barrels of
oil and natural gas liquids and approximately 2.3 billion cubic feet of natural
gas.

     In March 1999, the Company acquired for $800,000 a 100% working interest in
one natural gas well, associated natural gas gathering facilities and
underdeveloped lands in the East Carbon Field, located in Alberta, Canada from
Westdrum Energy Ltd. and C. & D. Oil and Gas Ltd. The acquisition was funded
with bank financing. The Company estimates that as of March 1, 1999, the
remaining proved reserves before royalty of the acquired property are
approximately 19,000 barrels of oil and natural gas liquids and approximately
720,000 mcf of natural gas.

     In March 1999, the Company acquired for $2.1 million working interests in
17 natural gas wells, associated natural gas gathering and compression
facilities in the East Carbon Field, located in Alberta, Canada from Cometra
Energy (Canada) Ltd. The acquisition was funded with bank financing. The
acquisition increased the Company's working interest ownership in the East
Carbon Field from 64% to 97%. The Company estimates that as of March 1, 1999,
the remaining proved reserves before royalty of the

                                       19
<PAGE>

acquired properties are approximately 48,000 barrels of oil and natural gas
liquids and approximately 2.1 billion cubic feet of natural gas.

     In April 1999, the Company acquired for $125,000 working interests in 13
natural gas wells, associated natural gas gathering and compression facilities
and undeveloped lands in the East Carbon Field, located in Alberta, Canada from
Springroad Resources, Inc. The acquisition was funded with bank financing. The
acquisition increased the Company's working interest ownership in the East
Carbon Field from 97% to approximately 100%. The Company estimates that as of
March 1, 1999, the remaining proved reserves before royalty of the acquired
properties are approximately 4,000 barrels of oil and natural gas liquids and
approximately 180,000 mcf of natural gas.

     On August 12, 1999, the Company entered into an agreement to acquire all of
the stock of Denver based Bonneville Fuels Corporation ("Bonneville"), an oil
and gas exploration and production company with working interests in
approximately 290 oil and natural gas wells and over 150,000 net acres located
in Colorado, Kansas, New Mexico, Texas, and Utah. Bonneville is a wholly owned
subsidiary of Bonneville Pacific Corporation. The purchase price for the stock
of Bonneville is approximately $24,000,000, subject to adjustments, plus debt of
approximately $6,500,000 remaining at Bonneville.

     Net proved reserves of Bonneville are estimated at approximately 250,000
barrels of oil and approximately 40 billion cubic feet of natural gas. Current
net production from the properties to be acquired is approximately 13,000 mcf of
gas per day and 200 barrels of oil per day.

     Carbon Energy Corporation ("Carbon"), a Colorado corporation, has been
formed and will receive from Yorktown Energy Partners III ("Yorktown"), equity
funds in the amount of $24,750,000 which will be used to purchase Bonneville
stock. Yorktown will purchase Carbon common stock at U.S. $5.50 per share. It is
intended that Carbon common stock will be listed on the American Stock Exchange.
Shareholders of CEC will be offered the opportunity to exchange their shares of
CEC for shares of Carbon on the basis of one share of CEC for one share of
Carbon. At the completion of the exchange offer, CEC will become a subsidiary of
Carbon. Closing of the Bonneville purchase is scheduled for October 31, 1999.
The exchange offer will commence later this year after effectiveness of a
registration statement to be filed with the Security and Exchange Commission.
Those arrangements are covered by an Exchange and Financing Agreement among
Carbon, CEC and Yorktown Energy III, L.P.

     Carbon on a consolidated basis with both Bonneville and CEC, will have
reserves of oil and natural gas more than four times larger than CEC; and Carbon
will have, in addition to CEC's Canadian operations, a base of operations in the
western region of the U.S. with potential for development of the acquired
properties and additional acquisitions in the U.S. and Canada. Reserves of the
combined companies will be approximately 52 bcf of gas and 475,000 barrels of
oil and natural gas liquids. The combined companies will have daily production
in excess of 18,000 mcf of gas per day and nearly 400 barrels of oil per day.

Exploration Activities

     Under the full cost method of accounting, all exploration costs associated
with continuing efforts to acquire or review prospects including outside
geological and seismic consultants are capitalized. A total of $201,000 of
exploration costs were capitalized during the first nine months of 1999 compared
to $40,000 in the first nine months of 1998.

Liquidity and Capital Resources

     The principal sources of the Company's funds are cash flows from operating
activities and available borrowings under the Company's financing commitment.

     For the first nine months of 1999, net cash from operating activities was
$1,389,000 compared to $1,218,000 for the same period in 1998. The increase is
primarily due to increased oil and gas sales, a positive net change in operating
assets and liabilities, partially offset by general and administrative expenses.
Net cash used in investing activities was $7,751,000 for the first nine months
of 1999 compared to $489,000 in 1998. This increase was primarily due to
acquisitions in the East Carbon Area and a deposit related to the Bonneville
Fuels acquisition. "See Acquisitions". Net cash provided by financing activities
in the first nine months of 1999 was $4,696,000 which was primarily due to the
proceeds from long-term debt, partially offset by the acquisition of 23,000
shares of the Company's common stock. Net cash used in financing activities in
the first nine months of 1998 was $79,000 due to the acquisition of 83,000
shares of the Company's common stock partially offset by the issuance of 70,000
shares of the Company's common stock.

     In December 1998, Resources received a financing commitment from Canadian
Imperial Bank of Commerce ("CIBC"). The purpose of the loan is to provide
financing for the acquisition of oil and gas reserves and for normal operating
requirements. The loan is secured by the Company's oil and gas assets. The
interest rate on outstanding borrowings is the CIBC Prime Rate plus 3/4%. The
initial commitment was a $2.5 million revolving loan. In March 1999, the
commitment was increased to a $5.0 million revolving loan. In October 1999, the
commitment was increased to a $6.5 million revolving loan. The commitment will
be reduced to $5.75 million upon closing of the Bonneville Fuels acquisition
"See Acquisitions". The revolving phase of the loan will expire on April 30,
2000 and may be renewed by CIBC. If the revolving commitment is not renewed by
CIBC, the loan would be converted into a term loan and will be permanently
reduced by way of consecutive monthly principal payments over a period not to
exceed 36 months. Borrowings under the loan during 1999 have resulted in
increased interest expense during 1999 compared to 1998.

Income Taxes

     In 1997, the Company adopted CICA 3465, Income Taxes. Since 1993, Resources
had paid current taxes to Revenue Canada based on its taxable income after
utilization, to the extent allowed, of its tax pool carry forwards. Currently
payable taxable income for future periods is dependent upon the level and type
of capital expenditures incurred in those future periods as well as percentage
limitations for utilization of existing tax pools. For 1999, the Company

Year 2000 Issues

     The Year 2000 issue is the result of computer programs being written using
two digits rather than four, or other methods, to define the applicable year.
Computer programs that have date sensitive software may recognize a date using
"00" as the year 1900, rather than the year 2000. This could result in a system
failure or miscalculations causing disruptions of operations, including among
other things, a temporary inability to price transactions, send invoices or
engage in similar normal business activities. In addition to affecting mainframe
and mid-range computer systems, this problem potentially impacts computer chips
integrated in security, plant automation, and pipeline control and metering
systems.

     Resources is currently completing an external review of all Year 2000
issues by contacting and/or sending out questionnaires to all of its natural gas
purchasers, gathering system and plant operators, downstream pipeline operators,
equipment and service providers, operators of its oil and gas properties,
financial institutions and vendors providing payroll and medical benefits and
services. The preliminary phase of this review has been completed. Based upon
this review, a schedule of revisions (if any) to existing systems as well as
requisite contingency plans will be designed and implemented.

     Resources utilizes a service bureau for its accounting processing. The oil
and gas accounting system utilized by the service bureau is Year 2000 compliant.
Resources has selected an accounting system and is in the process of bringing
all accounting services and processing in-house. The oil and gas accounting
system selected is Year 2000 compliant. Resources is also dependent upon
personal computer based software programs and files that may not be Year 2000
compliant. Resources has set a revised deadline of November 1999 to be
internally compliant with Year 2000 specifications.

                                       22
<PAGE>

     Management expects costs for Resources to become Year 2000 compliant will
not be significant. Resources does not believe that any loss of revenue will
occur as a result of the Year 2000 problem. However, despite Resosurces's
efforts to identify and remedy Year 2000 problems, there may be related failures
that disrupt Resources's business temporarily. In addition, the timetable for
Resources's planned completion of its own Year 2000 modifications and the
estimated costs to accomplish this are management's best estimates. These
assessments involve many assumptions concerning future events, including the
continued availability of certain resources, particularly personnel able to
locate, reprogram or replace, and test Resources's hardware and software in
accordance with Resources's established schedule. There can be no guarantee that
Resources's estimates will prove accurate, and actual results could differ
significantly because of the non-compliance of third parties of business
importance to Resources.

Item 3    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Market risk represents the risk of loss that may impact the financial
position, results of operation or cash flow of the Company due to adverse
changes in financial and commodity market prices and rates.

Market and Commodity Risk

     The Company's major market risk exposure is in the pricing applicable to
its oil and natural gas production. Pricing is primarily driven by the
prevailing prices for oil and gas in Central Alberta. Historically, prices
received for oil and gas production have been volatile and unpredictable.
Pricing volatility is expected to continue. A significant decline in the prices
of oil or natural gas could have a material adverse effect on the Company's
financial condition and results of operations.

     As described in Note 5 to the Financial Statements, from time to time, the
Company enters into commodity derivatives contracts and fixed-price physical
contracts to manage its exposure to oil and gas prices volatility and to support
oil and natural gas prices at targeted levels. The Company primarily uses
futures swap instruments to hedge its commodity prices. Realized gains or losses
from price risk management activities are recognized in oil and gas sales
revenues in the period in which the associated production occurs.

Inflation and Changes in Prices

     While certain of its costs are affected by the general level of inflation,
factors unique to the oil and natural gas industry result in independent price
fluctuations. Over the past five years, significant fluctuations have occurred
in oil and natural gas prices.

                                       23
<PAGE>

Although it is particularly difficult to estimate future prices of oil and
natural gas, price fluctuations have had, and will continue to have, a material
effect on the Company.

     In regard to interest rate risk, the Company has established a $6.5 million
credit facility with a Canadian bank as described in "Liquidity and Capital
Resources" under Item 2 "Management's Discussion of Analysis of Financial
Condition and Results of Operations". The interest rate for borrowings under
this facility is variable. In regard to foreign currency risk, the Company's
operations are primarily conducted in Canada. The Company does not use financial
instruments relating to currency and exchange rates. For information on the
exchange rate of the Canadian dollar, refer to "Exchange Rate of the Canadian
Dollar" under Item 2 "Management's Discussion and Analysis of Financial
Condition and Results of Operations".

warranty and representation in Section 4.1(p)) (which shall not survive the
Closing) and the procedures set forth in Sections 5.4 and 5.5.  Furthermore,
without limiting the provisions of the Confidentiality Agreement (which shall
continue in full force and effect) and except for the express representations
and warranties contained in Section 4.1, Seller makes no warranty or
representation, express, implied, statutory or otherwise, with respect to the
accuracy or completeness of the information, records and data now, heretofore or
hereafter made available to Buyer in connection with this Agreement, including,
without limitation, any description of the Assets, pricing assumptions,
potential for production of oil, gas or other hydrocarbons from the Subject
Interests, projected development costs, projected plugging and abandonment costs
or any other matters contained in or related to the Reserve Reports, any
environmental information, or any other material furnished to Buyer by Seller,
the Company or any other source, including any of their respective directors,
officers, employees, counsel, agents or advisors.

     Section 5.4   Environmental Review and Audit.
                   ------------------------------

     (a) Environmental Access.  For a period of forty-five (45) days following
         --------------------
the execution of this Agreement (the "Environmental Examination Period") and
subject to the restrictions contained in this Agreement and any required consent
or waiver of any third Person (other than an Affiliate of Seller), Seller shall
cause the Company (i) to permit Buyer and its representatives to have reasonable
access at reasonable times in the Company's offices, and in a manner so as not
to interfere unduly with the business operations of the Company, to Seller's and
the Company's environmental files and records in the Seller's or the Company's
possession relating to the Assets or any property formerly owned or operated by
the Company insofar as Seller and the Company may do so without waiving any
attorney/client, work product or like privilege and (ii) to permit Buyer and the
Environmental Consultant to have reasonable access to the Assets for the purpose
of allowing Buyer and the Environmental Consultant to inspect and/or

                                     -15-
<PAGE>

audit the Assets for any Environmental Defects (collectively, "Buyer's
Environmental Review"), all at Buyer's sole risk, cost and expense.

     (b)  Conduct of Review.  Prior to conducting Buyer's Environmental Review,
          -----------------
Buyer shall furnish Seller with a proposed scope of Buyer's Environmental
Review, including a description of the activities to be conducted and the
locations of such activities.  No third Person, other than the Environmental
Consultant and Buyer's employees and attorneys, may conduct Buyer's
Environmental Review.  Buyer shall not commence any activity proposed to be
included in Buyer's Environmental Review unless and until such activity
(including the location thereof) has been approved in writing by Seller, which
approval shall not be unreasonably withheld and shall be given or denied within
two Business Days after Buyer furnishes Seller with reasonably sufficient
information with respect to such activity.  Seller or its representative shall
have the right to be present during any inspection (including Buyer's
Environmental Review) of the Assets and shall have the right, at its option and
expense, to split samples with Buyer.

     (c)  Buyer Responsibility for Review.  In connection with Buyer's
          -------------------------------
Environmental Review, Buyer agrees that Buyer, the Environmental Consultant and
Buyer's employees, agents and contractors shall comply with all Laws and shall
exercise due care with respect to the Assets and their condition, taking into
consideration the characteristics of any wastes or substances found thereon, and
in light of all relevant facts and circumstances.  Specifically, but without
limitation, when handling solid waste or hazardous substances, if any,
discovered during the inspection of the Assets, Buyer, the Environmental
Consultant and Buyer's employees, agents and contractors shall handle such waste
or substances in accordance with all Laws.  Any soil or water samples taken by
Buyer from the Assets shall be managed by Buyer consistent with the applicable
rules and regulations of the U.S. Environmental Protection Agency and applicable
state agencies with regulatory authority, provided, the Company shall be
identified as the generator of such samples.  Promptly after completing Buyer's
Environmental Review, Buyer shall, at its sole cost and expense, restore the
Assets to substantially the same condition the Assets were in at the time of
Buyer's entry thereon, in accordance with good engineering practice, if changed
due to Buyer's Environmental Review.  Failure by Buyer to comply with the
requirements of this subsection within a reasonable time period will entitle
(but shall not obligate) Seller or the Company to take any action deemed
necessary or appropriate by Seller or the Company to correct such failure after
written notice to Buyer, all at Buyer's expense.  Buyer shall maintain and shall
cause its officers, employees, agents, representatives, contractors, consultants
(including the Environmental Consultant) and advisors to maintain all
information obtained by Buyer and the Environmental Consultant pursuant to the
Buyer's Environmental Review as strictly confidential and shall not disclose
same to any third Person without the prior written consent of Seller, except to
the extent required by Law.  Buyer shall provide Seller's counsel with copies of
any final written reports prepared and analytical test results received by Buyer
or the Environmental Consultant promptly following Buyer's or the Environmental
Consultant's preparation or receipt of same.  Buyer does hereby indemnify and
hold harmless, release and agree to defend the Seller Indemnified Parties and
the Company from and against any and all losses, costs, damages, obligations,
claims, liabilities, expenses and causes of action,

                                      -16-
<PAGE>

including all Environmental Liabilities, to the extent arising out of any
violation by Buyer or Buyer's officers, employees, agents, representatives,
contractors, consultants (including the Environmental Consultant) and advisors
of the provisions of this subsection or from the inspection or testing of the
Assets conducted by or on behalf of Buyer, including, without limitation, claims
for personal injuries, property damage and reasonable attorney's fees and
expenses, regardless of the form of claim whether at common law, strict
liability, negligence or under any statute or regulation. However, except to the
extent such inspections or testings materially contribute to, materially
aggravate or materially adversely affect an Environmental Defect, such
indemnification shall not extend to any Environmental Defect discovered in the
course of such inspections and testings, shall expire upon the Closing and shall
not in any way affect or limit Seller's liabilities or responsibilities with
respect to any Environmental Defect.

     Section 5.5   Environmental Defects.
                   ---------------------

     (a)  Buyer's Assertions of Environmental Defects.  Prior to the expiration
          -------------------------------------------
of the Environmental Examination Period, Buyer may notify Seller in writing of
any matters which, in Buyer's reasonable opinion, constitute Environmental
Defects.  Buyer's written notice must include (i) a specific description of each
Asset (or portion thereof) that is affected by the alleged Environmental Defect,
(ii) a description of the alleged Environmental Defect and the facts and
circumstances giving rise thereto, including all evidence compiled by Buyer
which supports the existence of such alleged Environmental Defect, and (iii) a
calculation of the Remediation Amount (itemized in reasonable detail) that Buyer
asserts is attributable to such Environmental Defect.  Buyer's calculation of
the Remediation Amount must describe the Remediation proposed for the
Environmental Condition that gives rise to the asserted Environmental Defect and
identify all material assumptions used by the Buyer in calculating the
Remediation Amount, including the standards the Buyer asserts must be met to
comply with Environmental Laws.

     (b)  Seller's Rights and Elections.  If Buyer timely notifies Seller in
          -----------------------------
writing of any Environmental Defect as required by Section 5.5(a), Seller shall
have the right to then or thereafter dispute the existence of such Environmental
Defect and/or the alleged Environmental Defect Amount asserted with respect
thereto in accordance with the provisions of Section 6.5 of this Agreement.  In
addition, Seller, at its option, shall elect, at or prior to the Closing, one of
the following options with respect to the Assets affected by the alleged
Environmental Defect and, at Seller's option, any other Assets which form part
of any field or other economic operating unit which includes such affected
Assets (collectively, the "Environmental Defect Property"):

          (i)  leave such Environmental Defect Property in the Assets and assume
     responsibility for the Remediation of such Environmental Defect; provided
     that, all costs for Remediation shall first be borne by Buyer to the extent
     Seller elects to apply any of the Environmental Defect Deductible to such
     costs; or

          (ii) leave such Environmental Defect Property in the Assets and reduce
     the Purchase Price by the Environmental Defect Amount with respect to such
     Environmental

                                      -17-
<PAGE>

     Defect (taking into account any application of the Environmental Defect
     Deductible which Seller elects to make with respect thereto).

If Seller elects the option set forth in clause (ii) above, Buyer shall be
deemed to have assumed responsibility for Remediation of such Environmental
Defect and such Environmental Defect shall be deemed to constitute a Company
Liability.  If Seller elects the option set forth in clause (i) above, Seller
shall use commercially reasonable efforts to implement such Remediation in a
manner which is consistent with the requirements of Environmental Laws and the
provisions of any applicable lease, and Seller shall have access to the
Environmental Defect Property after the Closing Date to implement and complete
such Remediation in accordance with this section and an Access Agreement in
substantially the form attached hereto as Exhibit 5.5(b) (the "Access
Agreement").  Seller will be deemed to have adequately completed the Remediation
required in the immediately preceding sentence (a) (i) upon receipt of a
certificate or approval from the applicable state or federal authority that the
Remediation has been implemented to the extent necessary to comply with existing
regulatory requirements or (ii) upon receipt of a certificate from a licensed
professional engineer if the approval or certification specified in (i) cannot
be obtained because provision for such approval or certification is not provided
under federal or state law and (b) to the extent express approval from the
lessor is required under any applicable lease, upon receipt of such approval.

     (c)  Environmental Defect Amount.  If Seller elects the option set forth in
          ---------------------------
Section 5.5(b)(ii) with respect to one or more Environmental Defects, then as
Buyer's sole and exclusive remedy with respect to such Environmental Defects,
Buyer shall be entitled to reduce the Purchase Price by the amount (the
"Environmental Defect Amount"), if any, by which the Remediation Amount with
respect to the Environmental Conditions giving rise to such Environmental
Defects exceeds that part, if any, of $500,000 (the "Environmental Defect
Deductible") which Seller elects to apply as an offset or deduction against such
Remediation Amount.  Seller may also apply any part of the Environmental Defect
Deductible to the cost of any Remediation undertaken by Seller pursuant to the
option set forth in Section 5.5(b)(i).  Any Remediation costs to which Seller
elects to apply the Environmental Defect Deductible shall be borne by the Buyer.
Seller shall have the right from time to time upon written notice to Buyer to
reallocate and change its application of the Environmental Defect Deductible,
except to the extent of Remediation costs already incurred or contracted for by
Buyer based on Seller's previous application thereof.  It is expressly
understood and agreed that the Environmental Defect Deductible represents an
aggregate deductible for Environmental Defects which may be apportioned as
provided in this Section 5.5(c) rather than as a separate deductible for each
individual Environmental Claim.

     (d)  Waiver by Buyer.  If, prior to the expiration of the Environmental
          ---------------
Examination Period, the Buyer has knowledge of an Environmental Defect and does
not notify Seller in writing of the existence thereof on or before the
expiration of the Environmental Examination Period (including, without
limitation, any Environmental Defect noted or described in any oral or written
report prepared by the Environmental Consultant), the Buyer shall be deemed to
have

                                      -18-
<PAGE>

waived such Environmental Defect and such Environmental Defect shall be deemed
to constitute a Company Liability. In addition, all conditions and matters of
which Buyer has knowledge prior to the expiration of the Environmental
Examination Period and which would have constituted Environmental Defects but
for the $50,000 threshold limitation set forth in the definition of
Environmental Defect shall be deemed to constitute Company Liabilities.


                                   ARTICLE 6
                               TITLE ADJUSTMENTS
                               -----------------

     Section 6.1   No Title Warranty or Representation.  Without limiting
                   -----------------------------------
Buyer's right to adjust the Purchase Price by operation of Section 6.2, Seller
makes no warranty or representation, express, implied, statutory or otherwise,
with respect to the Company's title to any of the Assets and Buyer hereby
acknowledges and agrees that Buyer's sole remedy for any defect of title,
including any Title Defect, with respect to any of the Assets shall be pursuant
to the procedures set forth in this Article VI, which remedies shall cease, and
be deemed to be finally and conclusively satisfied, in all respects, upon the
Closing.

     Section 6.2   Buyer's Title Review.
                   --------------------

     (a)  Buyer's Assertion of Title Defects.  For a period of forty-five (45)
          ----------------------------------
days following the execution of this Agreement (the "Title Examination Period"),
Buyer shall have the right to furnish Seller written notice meeting the
requirements of this Section 6.2(a) (the "Title Defect Notice") setting forth
any matters which, in Buyer's reasonable opinion, constitute Title Defects and
which Buyer asserts as a Title Defect with respect to any Well or Unit pursuant
to this Article VI.  For all purposes of this Agreement, Buyer shall be deemed
to have waived any Title Defect which Buyer fails to assert as a Title Defect by
a Title Defect Notice given to Seller on or before the expiration of the Title
Examination Period.  To be effective, Buyer's Title Defect Notice of a Title
Defect must include (i) a brief description of the matter constituting the
asserted Title Defect, (ii) the claimed Title Defect Amount attributable
thereto, and (iii) supporting documents reasonably necessary for Seller (as well
as any title attorney or examiner hired by Seller) to verify the existence of
such asserted Title Defect.  To give Seller an opportunity to commence reviewing
and curing Title Defects, on or before the end of each calendar week during the
Title Examination Period, Buyer agrees to give Seller written notice of all
Title Defects discovered by Buyer during such calendar week, which may be
preliminary in nature and supplemented prior to the end of the Title Examination
Period.  At the same time, Buyer shall also furnish Seller with written notice
of any Seller Title Credit which is discovered during such calendar week by any
of Buyer's employees or representatives while conducting Buyer's title review,
due diligence or investigation with respect to any Well or Unit.

     (b)  Purchase Price Allocations.  A portion of the Purchase Price has been
          --------------------------
allocated to the various Wells and Units in the manner and in accordance with
the respective values set forth in the Property Schedule.  If any adjustment is
made to the Purchase Price pursuant to this

                                      -19-
<PAGE>

Section 6.2, a corresponding adjustment shall be made to the portion of the
Purchase Price allocated to the affected Well or Unit in the Property Schedule.

     (c)  Seller's Rights and Opportunity to Cure.  If Buyer timely gives Seller
          ---------------------------------------
Title Defect Notice(s) of one or more Title Defects, Seller shall have the right
to then or thereafter dispute the existence of such Title Defect and/or the
alleged Title Defect Amount asserted with respect thereto in accordance with the
provisions of Section 6.5 of this Agreement.  In addition, the following terms
and conditions shall apply with respect to any Title Defect asserted by Buyer in
a timely Title Defect Notice:

          (i)   Seller shall have until two (2) days prior to the Closing Date,
     at its cost and expense, if it so elects but without obligation, to cure
     all or a portion of such asserted Title Defects.  Any asserted Title
     Defects which are waived by Buyer within such time shall be deemed
     "Permitted Encumbrances" hereunder.  Subject to Sections 6.2(c)(ii) and
     6.2(c)(iii) and Seller's continuing right to dispute the existence of a
     Title Defect and/or the Title Defect Amount asserted with respect thereto
     under Section 6.5, if Seller within such time fails to cure any Title
     Defect of which Buyer has given timely written notice as required above,
     and Buyer has not and does not waive same on or before the day immediately
     preceding the Closing Date, the Well or Unit affected by such uncured and
     unwaived Title Defect shall be a "Title Defect Property."

          (ii)  If Buyer furnishes to Seller timely Title Defect Notice(s) of
     one or more Title Defects and the same are not waived or cured as provided
     in Section 6.2(c)(i), Seller may elect to delay the Closing for a period of
     up to thirty (30) calendar days to afford Seller the opportunity, if it so
     elects, to attempt to cure any of the properly asserted Title Defects prior
     to the Closing. Subject to Section 6.2(c)(iii) and Seller's continuing
     right to dispute the existence of a Title Defect and/or the Title Defect
     Amount asserted with respect thereto under Section 6.5, if Seller within
     such time period fails or refuses to cure any Title Defect of which Buyer
     has given a timely Title Defect Notice and Buyer has not waived and does
     not waive the same before the delayed Closing, the Well or Unit affected by
     such uncured and unwaived Title Defect shall be a "Title Defect Property."

          (iii) If Buyer furnishes to Seller timely Title Defect Notice(s) of
     one or more Title Defects and the same are not waived or cured as provided
     in Section 6.2(c)(i) or Section 6.2(c)(ii), as applicable, Seller may elect
     to close the transactions contemplated hereby and retain the right to cure
     any of such Title Defects after Closing (whether or not Seller elects to
     delay Closing pursuant to Section 6.2(c)(ii) above). In such event, but
     subject to Seller's continuing right to dispute the existence of a Title
     Defect and/or the Title Defect Amount asserted with respect thereto under
     Section 6.5, the Purchase Price shall be subject to reduction pursuant to
     Section 6.2(d) taking into account all Title Defect Amounts attributable to
     the Title Defect Properties affected by the Title Defects which Seller may
     elect to cure after Closing. Seller shall have one hundred twenty (120)
     calendar days after the Closing Date (as may be delayed pursuant to Section
     6.2(c)(iii)

                                      -20-
<PAGE>

     above) in which to attempt to cure any such Title Defects and to increase
     or restore any Seller Title Credits. If Seller cures any such Title Defect,
     then Buyer shall promptly pay Seller the Title Defect Amount with respect
     to the Title Defect that is so cured, but not exceeding the aggregate
     amount of the reductions in the Purchase Price which Buyer received as a
     result of any Title Defects, together with interest on the amount due
     Seller from the Closing Date through and including the date of payment at
     the Agreed Rate. Furthermore, the Title Defect Deductible shall be restored
     to the extent any portion of the Title Defect Deductible was applied as a
     credit against the Title Defect Amount attributable to such cured Title
     Defect. If a positive balance exists in the Available Deductible Amount
     after any restorations or increases thereof pursuant to the foregoing, and
     Seller has suffered a reduction in the Purchase Price as a result of any
     one or more uncured Title Defects, Buyer shall pay to Seller an amount
     (together with interest thereon from the Closing Date through and including
     the date of payment at the Agreed Rate) equal to the lesser of (i) the
     amount by which the Purchase Price was reduced as a result of such uncured
     Title Defects and (ii) the then existing balance of the Available
     Deductible Amount.

     (d)  Buyer's Title Adjustments.  As Buyer's sole and exclusive remedy with
          -------------------------
respect to Title Defects, Buyer shall be entitled to reduce the Purchase Price
by the amount, if any, by which the aggregate amount of Title Defect Amounts
with respect to all Title Defect Properties exceeds the sum (the "Available
Deductible Amount") of $500,000 (the "Title Defect Deductible") plus the
aggregate amount of Seller Title Credits with respect to all Wells or Units.
"Title Defect Amount" shall mean, with respect to a Title Defect Property, the
amount by which the value of such Title Defect Property is impaired as a result
of the existence of one or more uncured and unwaived Title Defects, which amount
shall be determined as follows and subject to the following conditions:

          (1)  If the Title Defect results from the Company having a lesser Net
     Revenue Interest in such Title Defect Property than the Net Revenue
     Interest specified therefor in the Property Schedule, the Title Defect
     Amount shall be equal to the product obtained by multiplying the portion of
     the Purchase Price allocated to such Title Defect Property in the Property
     Schedule by a fraction, the numerator of which is the reduction in the Net
     Revenue Interest and the denominator of which is the Net Revenue Interest
     specified for such Title Defect Property in the Property Schedule.

          (2)  If the Title Defect results from the Company having a greater
     Working Interest in a Title Defect Property than the Working Interest
     specified therefor in the Property Schedule, the Title Defect Amount shall
     be equal to the product obtained by multiplying the portion of the Purchase
     Price allocated to such Title Defect Property in the Property Schedule by a
     fraction, the numerator of which is the increase in the Working Interest
     and the denominator of which is the Working Interest specified for such
     Title Defect Property in the Property Schedule.

                                      -21-
<PAGE>

          (3)  If the Title Defect results from the existence of a lien, the
     Title Defect Amount shall be an amount sufficient to discharge such lien.

          (4)  If the Title Defect results from any matter not described in
     paragraphs (1), (2) or (3) above, the Title Defect Amount shall be an
     amount equal to the difference between the value of the Title Defect
     Property affected by such Title Defect with such Title Defect and the value
     of such Title Defect Property without such Title Defect (taking into.
     account the portion of the Purchase Price allocated in the Property
     Schedule to such Title Defect Property); provided, that if such Title
     Defect is reasonably susceptible of being cured, the Title Defect Amount
     shall be the reasonable cost and expense of curing such Title Defect, if
     less.

          (5)  If a Title Defect is not effective or does not affect a Title
     Defect Property throughout the entire productive life of such Title Defect
     Property, such fact shall be taken into account in determining the Title
     Defect Amount.

          (6)  The Title Defect Amount with respect to a Title Defect Property
     shall be determined without duplication of any costs or losses included in
     another Title Defect Amount hereunder.

          (7)  The Title Defect Amount attributable to a Title Defect Property
     shall not exceed the portion of the Purchase Price allocated to such Title
     Defect Property in Section 6.2(b).

          (8)  No Title Defect Amount shall be allowed on account of and to the
     extent that an increase in the Company's Working Interest in a Well or Unit
     has the effect of proportionately increasing the Company's Net Revenue
     Interest in such Well or Unit.

          (9)  With respect to any Well or Unit in which Buyer or an Affiliate
     of Buyer likewise owned an undivided interest at the Effective Time, no
     Title Defect Amount shall be allowed on account of a Title Defect affecting
     such Subject Interest that also affected Buyer's or such Affiliate's
     interest in such Well or Unit in the same manner at the Effective Time.

          (10) Notwithstanding the foregoing, if the Title Defect Amount
     determined pursuant to the foregoing with respect to a Title Defect
     Property is $50,000 or less, after taking into account any curative work
     performed by or on behalf of Seller, then the Title Defect Amount with
     respect to such Title Defect Property shall be deemed zero.

     Section 6.3   Determination of Title Defects.  A Well or Unit shall not be
                   ------------------------------
deemed to have a "Title Defect" if the following statements are true in all
material respects with respect to such Well or Unit as of the Closing Date:

                                      -22-
<PAGE>

     (a)  The Company has Defensible Title thereto.

     (b)  All rentals, Pugh clause payments, shut-in gas payments and other
similar payments (other than royalties, overriding royalties and other similar
payments on production) due with respect to such Well or Unit have been properly
and timely paid.

     (c)  Seller is not in default under the material terms of any leases,
farmout agreements or other contracts or agreements respecting such Well or Unit
which could (1) prevent the Company from receiving the proceeds of production
attributable to the Company's interest therein, or (2) result in cancellation of
the Company's interest therein.

Notwithstanding any other provision in this Agreement to the contrary, the
following matters shall not be asserted as, and shall not constitute Title
Defects: (i) defects in the chain of title such as minor name discrepancies, the
mere failure to recite marital status in a document, or omissions of successions
of heirship proceedings, unless Buyer provides affirmative evidence that such
failure or omission results in another Person's superior claim of title to the
relevant Subject Interest or portion thereof, (ii) defects arising out of lack
of survey, (iii) defects arising out of lack of corporate authorization, unless
Buyer provides affirmative evidence that such lack of authorization results in
another Person's superior claim of title to the relevant Subject Interest or
portion thereof, (iv) the failure to obtain or absence of any federal patent or
conveyance with respect to any lands over which any state has claimed ownership
and which have been covered by a state lease for more than ten years, (v)
defects that have been cured by possession under the applicable statutes of
limitations or statutes for prescription and (vi) other defects of a type
expected to be encountered in the area involved and customarily acceptable to
prudent operators and interest owners.  Furthermore, in determining the
existence of a Title Defect, due consideration shall be given to the length of
time hydrocarbons have been produced from the affected property in an undisputed
"pay status" without any adverse claim even though such period may be less than
the period of possession or use required under applicable limitations or
prescription statutes.  (As used herein, "pay status" shall mean payment is
being made by a third party for production from the affected Well or Unit
without indemnity from the Company except such indemnities as are customarily
included in division orders, transfer orders, product purchase agreements and
similar documents commonly used in connection with the payment of proceeds from
production.)

     Section 6.4   Seller Title Credit.  A "Seller Title Credit" shall mean,
                   -------------------
with respect to a Well or Unit, the amount by which the value of such Well or
Unit is enhanced by virtue of (a) the Company having a greater Net Revenue
Interest in such Well or Unit than the Net Revenue specified therefor in the
Property Schedule, (b) the Company having a lesser Working Interest in such Well
or Unit than the Working Interest specified therefor in the Property Schedule,
or (c) such Well or Unit being subject to a lien indebtedness which is less than
that used for the Purchase Price allocation in the Property Schedule, which
amount shall be determined as follows:

                                      -23-
<PAGE>

          (1)  If the Seller Title Credit results from the Company having a
     greater Net Revenue Interest in such Well or Unit than the Net Revenue
     Interest specified therefor in the Property Schedule, the Seller Title
     Credit shall be equal to the product obtained by multiplying the portion of
     the Purchase Price allocated to such Well or Unit in the Property Schedule
     by a fraction, the numerator of which is the increase in the Net Revenue
     Interest and the denominator of which is the Net Revenue Interest specified
     for such Well or Unit in the Property Schedule.

          (2)  If the Seller Title Credit results from the Company having a
     lesser Working Interest in a Well or Unit than the Working Interest
     specified therefor in the Property Schedule, the Seller Title Credit shall
     be equal to the product obtained by multiplying the portion of the Purchase
     Price allocated to such Well or Unit in the Property Schedule by a
     fraction, the numerator of which is the decrease in the Working Interest
     and the denominator of which is the Working Interest specified for such
     Well or Unit in the Property Schedule.

          (3)  If the Seller Title Credit results from a Well or Unit being
     subject to lesser lien indebtedness, the Seller Title Credit shall be equal
     to the amount of the Company's proportionate share of the reduction in such
     lien indebtedness; provided that, if lien indebtedness affects more than
     one Well or Unit, the Seller Title Credits with respect to such Wells or
     Units shall be determined without duplication (e.g., credit shall not be
     given twice to the same reduction in indebtedness);and provided further, no
     Seller Title Credit shall be allowed to the extent such lien indebtedness
     is paid by the Company after the Report Date and is not reimbursed by
     Seller.

          (4)  In determining the amount of Seller Title Credits, the principles
     and methodology set forth in paragraphs (5), (6) and (7) of Section 6.2(d)
     shall be applied, mutatis mutandis.
                       ----------------

          (5)  No Seller Title Credit shall be allowed on account of and to the
     extent that a decrease in the Company's Working Interest in a Well or Unit
     has the effect of proportionately decreasing the Company's Net Revenue
     Interest in such Well or Unit.

          (6)  Notwithstanding the foregoing, if the Seller Title Credit
     determined pursuant to the foregoing with respect to any Well or Unit is
     $50,000 or less, then the Seller Title Credit with respect thereto shall be
     deemed zero.

The Title Defect Deductible shall be increased dollar for dollar by the
aggregate amount of all Seller Title Credits.  In addition, the Title Defect
Deductible shall be restored to the extent that any portion thereof is applied
as a credit against a Title Defect Amount attributable to a Title Defect which
is subsequently cured by Seller or determined not to constitute a Title Defect.

     Section 6.5   Deferred Claims and Disputes.  In the event that Buyer and
                   ----------------------------
Seller have not agreed upon (i) the existence of one or more Title Defects or
Seller Title Credits or one or more adjustments, credits or offsets claimed by
Buyer or Seller pursuant to and in accordance with the requirements of this
Article VI, or (ii) the existence of one or more Environmental Defects, any
Remediation, Remediation Amount or plan therefor, or one or more adjustments,
credits or offsets claimed by Buyer or Seller pursuant to Section 5.5, any such
dispute or claim (a "Deferred Adjustment Claim") shall be settled pursuant to
this Section 6.5 and, except as provided in Sections 9.1(f), 9.2(f) and 9.4,
shall not prevent or delay Closing.  In no event shall any Title Defect Amount,
Environmental Defect Amount or Remediation Amount asserted by Buyer, or any
Seller Title Credit asserted by Seller, as a Deferred Adjustment Claim exceed
the amount asserted by Buyer or Seller therefor prior to the end of the Title
Examination Period in accordance with Section 6.2 or the Environmental
Examination Period in accordance with Section 5.5, as applicable.  With respect
to each potential Deferred Adjustment Claim, Buyer and Seller shall deliver to
the other a written notice describing each such potential Deferred Adjustment
Claim, the amount in dispute and a statement setting forth the facts and
circumstances that support such party's position with respect to such Deferred
Adjustment Claim.  At Closing, the Purchase Price shall not be adjusted on
account of, and, except as provided in Sections 9.1(f) and 9.2(f), no effect
shall be given to, the Deferred Adjustment Claim.  On or prior to the thirtieth
(30th) consecutive calendar day following the Closing Date or, if earlier, the
date which was the "Closing Date" before Closing was delayed under Section 9.4
(the "Deferred Matters Date"), the Seller and Buyer shall attempt in good faith
to reach agreement on the Deferred Adjustment Claims and, ultimately, to resolve
by written agreement all disputes regarding the Deferred Adjustment Claims.  Any
Deferred Adjustment Claims which are not so resolved on or before the Deferred
Matters Date may be submitted by either party to final and binding arbitration
in accordance with the Arbitration Procedures; provided, however, that the
Seller may elect at any time to resolve all disputes relating to the Deferred
Adjustment Claims by the payment to Buyer of the amount by which the Purchase
Price would have been reduced at Closing on account of the Title Defects or
Environmental Defects which constitute Deferred Adjustment Claims if same did
not constitute Deferred Adjustment Claims, together with interest thereon from
the Closing Date to the date of such payment at the Agreed Rate.
Notwithstanding anything herein provided to the contrary, including Section
6.2(c), but without limiting Seller's rights under Sections 6.2(c)(ii) and
6.2(c)(iii), Seller shall be entitled to cure any Title Defect which constitutes
a Deferred Adjustment Claim at any time prior to the point in time when a final
and binding written decision of the board of arbitrators is made with respect
thereto in accordance with the Arbitration Procedures.  The amount of any
reduction in the Purchase Price to which Buyer becomes entitled under the final
and binding written decision of the board of arbitrators shall be promptly
refunded by Seller to Buyer, together with interest thereon from the Closing
Date to the date of payment at the Agreed Rate.

     Section 6.6   No Duplication.  Notwithstanding anything herein provided to
                   --------------
the contrary, if a Title Defect results from any matter which could also result
in the breach of any representation or warranty of Seller set forth in Section
4.1, then Buyer shall only be entitled to

                                      -25-
<PAGE>

assert such matter as a Title Defect pursuant to this Article VI and shall be
precluded from also asserting such matter as the basis of the breach of any such
representation or warranty.

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

     Section 7.1   Tax Agreements.
                   --------------

     (a)  Tax Return Filings and Tax Payments for 1999. Seller shall include the
          --------------------------------------------
Company in its consolidated federal income Tax Return, and in those state, local
and foreign income Tax Returns that are filed on a consolidated, combined,
unitary or nonunitary basis, for its tax period that includes the Closing Date,
and Seller shall be responsible for the payment of, and shall indemnify and hold
harmless the Buyer against, all Taxes required to be paid with respect to such
consolidated, combined, unitary or nonunitary Tax Returns.  Such Tax Returns
shall include (a) the income and gains resulting from the purchase and sale of
the Company Shares, including, without limitation, any gain or loss recognized
pursuant to any Section 338(h)(10) Election made pursuant to Section 7.1(d)
below, (b) any deferred income and gain taken into income by reason of Treasury
Regulation Section 1.1502-13 or any similar provision of state, local or foreign
law, and (c) all other items of income, gain, loss, deduction and credit of the
Company for the period up to and including the Closing Date, as determined by
closing the books of the Company as of the end of the Closing Date; provided,
however, such Tax Return shall not include any income, gain, loss, deduction or
credit of the Company arising as a result of action of Buyer or the Company
taken after the Closing, and all such Tax Returns shall be prepared in a manner
consistent with past practice (including any Tax elections and methods of
accounting), unless a contrary treatment is required by a change in Law (or the
judicial or administrative interpretations thereof).

     (b)  Termination of Existing Income Tax Sharing Agreements.  The Seller
          -----------------------------------------------------
shall cause any existing income tax sharing agreements or arrangements disclosed
on Schedule 4.1(q) to be terminated as of the Closing Date.  The Company shall
not be obligated to pay the Seller (or Seller's successor in interest) for any
tax benefit it receives from the utilization of net operating losses in Seller's
consolidated return filing for any period to and including the Closing Date.
The Company shall have no liability to Seller or Seller's Affiliates for any
income taxes with respect to any periods ending on or prior to the Closing Date.

     (c)  State and Local Taxes/Refunds.  Buyer shall prepare or cause to be
          -----------------------------
prepared with respect to Taxes other than income Taxes and file or cause to be
filed any Tax Returns of the Company for Tax periods which begin before the
Closing Date and end after the Closing Date.  With respect to Taxes (other than
Taxes to be included by Seller in its Tax Returns as required in Section 7.1(a)
above) that are imposed on a periodic basis and are payable for a taxable period
that includes (but does not end on) the Closing Date, the Company has accrued as
of March 31, 1999, and is continuing to accrue reserves for Taxes through the
Closing Date.  The parties agree

                                      -26-
<PAGE>

that such accruals will be a final settlement as between the parties for all
liabilities relating to such taxes and that no adjustments or refunds will be
made with respect thereto.

     (d)  Section 338(h)(10) Election.  At Buyer's option, Seller (or Seller's
          ---------------------------
successor in interest) (or if applicable, its ultimate parent corporation) will
join with Buyer in making an election under Section 338(h)(10) of the Code (and
any corresponding elections under state, local, or foreign tax law)
(collectively, a "Section 338(h)(10) Election") with respect to the purchase and
sale of the stock of the Company hereunder.  Seller (or Seller's successor in
interest) will pay any Tax attributable to the making of the Section 338(h)(10)
Election and will indemnify the Buyer and the Company against any liability
arising out of any failure to pay such Tax.  Seller will also pay any state,
local or foreign Tax (and indemnify Buyer and Company against any liability
arising out of any failure to pay such Tax) attributable to an election under
state, local, or foreign law similar to the election available under Section
338(g) of the Code (or which results from the making of an election under 338(g)
of the Code) with respect to the purchase and sale of stock of the Company
hereunder.

     (e)  Allocation of Purchase Price.  The parties agree to negotiate in good
          ----------------------------
faith to agree upon an allocation of the Purchase Price for Tax purposes among
the Company's Assets as promptly as possible after Closing; and the parties
further agree that for all income and franchise tax purposes (and, where
applicable, financial accounting purposes), including but not limited to section
338 of the Code, they and their Affiliates will report consistently with such
allocation; provided if no such allocation is agreed upon within one (1) year
following Closing, the parties will not be required to report on a consistent
basis.

     Section 7.2   Employee Matters.
                   ----------------

     (a)  Maintenance of Health Benefit Program.  From and after Closing, and
          -------------------------------------
until a date not earlier than the expiration of the Trust provided for under
Section 7.2(b), Buyer agrees to cause the Company to (a) maintain equal or
greater medical benefit coverage under the same or better terms and conditions
as is provided under the Company's existing plans which plans are in effect
immediately prior to the Closing Date and which provide benefits to current and
former Company employees covered under such plans as of the date of this
Agreement and their covered dependents, and (b) fulfill the medical benefit
commitments described on Schedule 4.1(r).

     (b)  Employee Benefits Trust. Prior to Closing, the Company shall establish
          -----------------------
a trust, pursuant to an Employee Benefits Trust Agreement substantially in the
form attached hereto as Exhibit "C," for the purpose of providing salary
continuation and benefits under the Company's insurance plans for the periods
provided and in accordance with the terms set forth in Exhibit "C."  Prior to
Closing, the Company shall fund the Employee Benefits Trust with not more than
$1,730,000 to cover the obligations to such employees of the Company under the
terms of the Employee Benefits Trust Agreement, the letters describing severance
benefits dated March 30, 1999 and April 11, 1999, and each and every employment
agreement with an employee of the Company, and such funding shall not cause any
adjustment in the Purchase Price. Unutilized

                                      -27-
<PAGE>

funds in the trust shall be the property of the Company as set forth in the
Employee Benefits Trust Agreement. Prior to the Closing, no change in the
Employee Benefits Trust Agreement from the form attached hereto as Exhibit "C"
shall be made without the prior written consent of Buyer, which consent shall
not be unreasonably withheld. Any payment made pursuant to the terms of the
Employee Benefits Trust shall comply with ERISA regulation '2510.3.2(b).

     (c)  Company Employee Benefits.  With respect to those employees of the
          -------------------------
Company who continue their employment with the Company after the Closing Date or
are hired by the Buyer or an Affiliate of Buyer within the six (6) month period
following the Closing Date, Buyer shall, or shall cause the Company or the
Buyer's Affiliates to, take all action necessary to cause all such employees to
be covered under the employee benefit plans and fringe benefit arrangements of
the Company, Buyer or Buyer's Affiliates, as the case may be, on the same basis
as those provided to employees of Buyer or its Affiliates who hold comparable
positions, as determined by Buyer in its discretion; and further provided that
Buyer's or its Affiliates' health plans shall not impose any preexisting
condition or waiting period requirement on any such employee's participation in
such health plan with respect to conditions currently permitted to be covered
thereunder if such employee enrolls within thirty (30) days of beginning
employment with Buyer or Buyer's Affiliate.  Buyer or Buyer's Affiliate shall
grant all such employees credit for purposes of eligibility and vesting under
Buyer's or its Affiliate's employee benefit plans (including vacation and
severance) for their service with the Company prior to the Closing Date.  If
Buyer or its Affiliates give credit under their employee vacation plans for oil
and gas industry experience, such employees shall be given credit for their
years of industry experience prior to the Closing Date for vacation plan
purposes rather than for their years of service with the Company prior to the
Closing Date.

     (d)  Severance of Employment Relationship With Certain Employees.  As of or
          -----------------------------------------------------------
prior to the Closing Date, Seller shall cause the Company to sever its
employment relationship with any person who is designated by Buyer in accordance
with the provisions of this Section 7.2(d).  No later than ten (10) Business
Days prior to Closing, Buyer shall provide Seller with irrevocable written
notice of which employees of Company will not continue to be employed by the
Company following the Closing Date.  Buyer agrees to make its determination and
selection of such employees in compliance with applicable federal and state
laws.  Within five (5) Business Days after Seller receives such written notice
regarding an employee, Seller will cause the Company to provide such employee
with written notice of the date of such employee's severance of employment with
the Company, which notice shall comply with the requirements of any employment
agreement, as applicable,  and with the notice requirements of ERISA ''606 and
701.

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

          (1)  cause the Assets to be maintained and operated in the ordinary
     course of business in accordance with the Company's past practices

     operation or capital expenditure (net to the Company's interest and without
     consideration of any cost overruns) is in excess of $500,000 in any single
     instance, or if the Company's election not to participate in such operation
     or capital expenditure would cause a permanent forfeiture of any Well or

     requesting such consent which notice shall set forth the Company's
     recommendation as to whether the Company should participate in such

     approval of the recommendation of the Company set forth in such notice with
     respect to such operation or capital expenditure;

<PAGE>

          (4)  maintain and keep the Assets in full force and effect, except
     where such failure is due to (i) the failure to pay a delay rental,
     royalty, shut in royalty or other payment by mistake or oversight
     (including the Company's negligence) unless caused by the Company's gross
     negligence or willful misconduct, or (ii) the failure to participate in an
     operation due to the express or deemed nonconsent of Buyer; and

          (5)  use reasonable diligence to maintain its relationships with
     suppliers, customers and others having material business relations with the
     Company with respect to the Assets so that they will be preserved for Buyer
     on and after the Closing Date.

     (d)  Contracts and Agreements.  The Company shall not:
          ------------------------

          (1)  grant or create any Preference Right or Transfer Requirement with
     respect to the Assets except (i) in connection with the performance by the
     Company of an obligation or agreement existing on the date hereof or
     pursuant to this Agreement or (ii) in connection with the acquisition of
     Assets after the Effective Time if granting or creating such Preference
     Right or Transfer Requirement is a condition of such acquisition;

          (2)  enter into any oil, gas or other hydrocarbon sales, exchange,
     processing or transportation contract with respect to the Assets having a
     term in excess of one year which is not terminable without penalty on

     (a)  Emergencies; Legal Requirements.  Seller or the Company may take (or
          -------------------------------
not take, as the case may be) any of the actions mentioned in Section 8.1 above
if reasonably necessary under emergency circumstances (or if required or
prohibited (as the case may be) pursuant to Law) and provided, Buyer is notified
as soon thereafter as practicable.

     (b)  Non-Operated Properties.  If the Company is not the operator of a
          -----------------------
particular portion of the Assets, the obligations of the Company in Section 8.1
above with respect to such portion of the Assets which have reference to
operations or activities that pursuant to existing contracts are carried out or
performed by the operator, shall be construed to require only that the Company
use reasonable diligence (without being obligated to incur any expense or
institute any cause of action) to cause the operator of such portion of the
Assets to take such actions or render such performance within the constraints of
the applicable operating agreements and other applicable agreements.

     (c)  Certain Operations.
          ------------------

          (1)  Should the Company not wish to pay any lease rental or other
     payment or participate in any reworking, deepening, drilling, completion,
     equipping or other operation on or with respect to any well or other Well
     or Unit which may otherwise be required by Section 8.1 above, the Company
     shall give Buyer written notice thereof at least fifteen (15) days prior to
     the date such rental or other payment is due or, in the case of an
     operation, promptly after the Company receives notice of such proposed
     operation from the operator of such property (or if the Company is the
     operator, at the same time the Company gives or is required to give notice
     of such proposed operation to the non-operators of such property).  The
     Company shall not be obligated to make any such payment or to elect to
     participate in any such operation which the Company does not wish to make
     or participate in unless the Company receives from Buyer, within a
     reasonable time prior to the date when such payment or election is required
     to be made by the Company, (a) the written election and agreement of Buyer
     (i) to require the Company to take such action and (ii) to pay all costs
     and expenses of the Company with respect to such lease rental or other
     payment or such operation and (b) the funds necessary for such payment or

          (2)  If a notice delivered to Buyer pursuant to Section 8.1(c)(3) sets
     forth a recommendation that the Company participate in an operation or
     capital expenditure the failure in which to participate will cause the
     forfeiture of all or any portion of a Subject Interest (or any interest in
     production attributable thereto) and the Buyer timely notifies Seller that
     it does not desire the Company to participate in same, then the resulting
     forfeiture shall not be a Title Defect nor shall the Subject Interest
     affected be a Title Defect Property for purposes of this Agreement.

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

     Section 9.1   Seller's Closing Conditions.  The obligation of Seller to

material respects on and as of the Closing Date, and (2) covenants and
agreements of Buyer to be performed on or before the Closing Date in accordance
with this Agreement shall have been duly performed in all material respects;
provided however, for purposes of this Section 9.1(a), in determining whether
this condition has been satisfied, any such representation, warranty, covenant
or agreement of Buyer contained in this Agreement which is qualified by
materiality shall be read and interpreted as if such qualification was not
included therein (it being the intent of the parties not to apply a double
materiality threshold in determining the satisfaction of this condition).

     (b)  Officer's Certificate.  Seller shall have received a certificate dated
          ---------------------
as of the Closing Date, executed by a duly authorized officer of Buyer, to the
effect that to such officer's knowledge the conditions set forth in subsection
(a) of this Section 9.1 have been satisfied.

     (c)  Closing Documents.  On or prior to the Closing Date, Buyer shall have
          -----------------
delivered, or be standing ready to deliver at Closing, all agreements,
instruments and other documents required to be delivered by Buyer pursuant to

<PAGE>

any court or governmental agency or body of competent jurisdiction seeking to
enjoin or restrain the consummation of the Closing or recover damages from
Seller or any Affiliate of Seller resulting therefrom.

     (e)  Opinion of Counsel.  Buyer shall have delivered to Seller the written
          ------------------
opinion of counsel to Buyer, dated as of the Closing Date, which counsel shall

          -----------
account of the aggregate (net) amount of all Environmental Defect Amounts and
Title Defect Amounts, and (ii) the aggregate  amount of Environmental Defect
Amounts and Title Defect Amounts claimed by Buyer with respect to unresolved
Deferred Adjustment Claims shall not exceed $3,000,000.

     (g)  Seller Shareholder Approval.  The transactions provided for under this
          ---------------------------
Agreement shall have been approved by Seller's shareholders, provided that

General Corporation Law of Delaware, which opinion shall be from a firm and in a
form and substance reasonably satisfactory to Buyer and Buyer's counsel.

     Section 9.2   Buyer's Closing Conditions.  The obligation of Buyer to
                   --------------------------
proceed with the Closing contemplated hereby is subject, at the option of Buyer,
to the satisfaction on or prior to the Closing Date of all of the following
conditions:

Adverse Effect qualifier shall be true and correct in all material respects on
and as of the Closing Date as though made as of the Closing Date, and (2) the
covenants and agreements of Seller to be performed on or before the Closing Date
in accordance with this Agreement shall have been duly performed in all material
respects.

If the Seller breaches any of the representations and warranties of the Seller
contained herein, which breaches individually would not have a Material Adverse
Effect, but that in the aggregate would exceed $1,000,000 (an "Aggregate
Material Adverse Effect"), on or before the Closing Date, the Buyer may notify
the Seller of such Aggregate Material Adverse Effect, and Seller shall have
right to (x) extend the Closing Date by no more than ten days and cure the
breaches underlying the Aggregate Material Adverse Effect to the satisfaction of
the Buyer within such ten-day period or (y) reduce the Purchase Price by the
estimated amount of such Aggregate Material Adverse Effect, it being understood
by the parties that if the Seller (x) cures such breaches to the satisfaction of
the Buyer within such ten-day period or (y) adjusts the Purchase Price
accordingly, the Buyer shall not have the right to terminate this Agreement
under this Section 9.2(a).  Notwithstanding the foregoing, for purposes of
determining whether breaches of Seller's representations and warranties have an
"Aggregate Material Adverse Effect," any

                                      -38-
<PAGE>

breaches of any single representation and warranty which have an adverse effect
on the value of the Company of $200,000 or less will be treated as having a
value of zero. In addition, Buyer agrees to use diligent efforts to notify
Seller of any asserted breach of Seller's representations and warranties as soon
as reasonably possible so that Seller, at its option, can attempt to cure such
asserted breaches.

     (b)  Officer's Certificate.  Buyer shall have received a certificate dated
          ---------------------
as of the Closing Date, executed by a duly authorized officer of the Seller and

competent jurisdiction seeking to enjoin or restrain the consummation of the
Closing or recover damages from Buyer or any Affiliate of Buyer resulting
therefrom.

be reasonably acceptable to Buyer, substantially in the form attached hereto as
Exhibit 9.2(e).

     (f)  Adjustments.  The sum of (i) the reductions in the Purchase Price on
          -----------

Title Defect Amounts, and (ii) the aggregate  amount of Environmental Defect
Amounts and Title Defect Amounts claimed by Buyer with respect to unresolved

     Section 9.3   Regulatory Approvals.  If Buyer or Seller determines that
                   --------------------
approval of a Governmental Authority is required to permit the Company or Buyer
to continue to use any governmental permits with respect to the Assets or the
Company after Closing, Buyer and Seller shall, as promptly as practicable after
the date of this Agreement, cooperate in filing the required applications and
notices with the appropriate Governmental Authorities seeking authorization to
confirm the Company's continued right to use such permits or to transfer or
assign such permits to Buyer (the "Regulatory Approvals") as necessary.  To the
extent assignable and assignment to Buyer is necessary in the foregoing context,
Seller will cause the Company to assign such permits to Buyer at the Closing.
Each party agrees to use reasonable diligence to obtain the Regulatory Approvals
and the parties agree to cooperate fully with each other and with all
Governmental Authorities to obtain the Regulatory Approvals at the earliest
practicable date.

     Section 9.4   Deferred Adjustment Claims Extension.  Notwithstanding
                   ------------------------------------
Section 9.2(f), if Buyer elects not to proceed with the Closing as a result of
the non-satisfaction of the condition set forth in Section 9.2(f) and such
condition would have been satisfied but for the amount of Environmental Defect
Amounts and Title Defect Amounts claimed by Buyer with respect to unresolved
Deferred Adjustment Claims, Seller may elect to delay the Closing until the
tenth Business Day following the date when a sufficient amount of such Deferred
Adjustment Claims have been resolved pursuant to Section 6.5 to determine that
the condition set forth in Section 6.5 has been satisfied or has not been
satisfied.  A Deferred Adjustment Claim will be deemed resolved pursuant to
Section 6.5 when a final and binding written decision of the board of
arbitrators is made with respect thereto in accordance with the Arbitration
Procedures.

     Section 9.5   Failure to Disclose.  The breach by Seller of its obligation
                   -------------------
to give notice to Buyer under Section 4.1(cc) and the breach by Buyer of its
obligation to give notice to Seller under Section 4.2(j) shall not constitute a
failure of the conditions to Closing under Sections 9.1 and 9.2. From and after
Closing, neither Buyer nor Seller shall have any obligation or liability under
this Agreement or in connection with the transaction contemplated in this
Agreement for any breach of a representation or warranty by such party prior to
Closing by reason of any fact or facts of which the other party had knowledge
prior to Closing if and to the extent such other party breached its obligation
to give notice of such fact or facts to the other party pursuant to Section
4.1(cc) or 4.2(j), as applicable.  From and after Closing, this Section 9.5
shall constitute the sole remedy of Buyer and Seller for the other party's
breach of Section 4.1(cc) or 4.2(j), as the case may be.

Buyer

                                      -43-
<PAGE>

shall indemnify and hold harmless the Seller and all Seller Indemnified Parties
(other than the Company), each of their respective past, present and future
directors, officers, employees, consultants and agents, each of the Company's
past and present (and, through the Closing, future) directors, officers,
employees, consultants and agents), and each of the directors, officers, heirs,
executors, successors and assigns of any of the foregoing (collectively, the
"Seller Indemnified Parties") from and against any and all (i) Company
Liabilities incurred by or asserted against any of the Seller Indemnified
Parties, INCLUDING, WITHOUT LIMITATION, ANY COMPANY LIABILITY BASED ON
NEGLIGENCE OR STRICT LIABILITY OF THE SELLER INDEMNIFIED PARTIES OR ANY OTHER
THEORY OF LIABILITY, WHETHER IN LAW (WHETHER COMMON OR STATUTORY) OR EQUITY BUT
NOT INCLUDING COMPANY LIABILITIES BASED ON GROSS NEGLIGENCE OR WILLFUL

of Section 11.1 and Article XII, any Covered Liability resulting from, arising
out of or on account of any breach, failure or nonfulfillment of any
representation, warranty, covenant or agreement on the part of Buyer which is

     Section 13.2   Third Party Claims.  If a claim by a third party is made
                    ------------------
against a Seller Indemnified Party, and if such party (the "Indemnified Party")
intends to seek indemnity with respect thereto under Section 5.1, 5.4, 8.7, or
13.1, the Indemnified Party shall promptly furnish written notice to Buyer (the
"Indemnitor"), of such claims. The Indemnitor shall have thirty (30) days after
receipt of such notice to undertake, conduct and control, through counsel of its
own choosing and at its own expense, the settlement or defense thereof, and the
Indemnified Party shall cooperate with it in connection therewith; provided that
the Indemnitor shall permit the Indemnified Party to participate in such
settlement or defense through counsel chosen by such Indemnified Party, however,
the fees and expenses of such counsel shall be borne by such Indemnified Party.
So long as the Indemnitor, at Indemnitor's cost and expense, (1) has undertaken
the defense of, and assumed full responsibility for all indemnified liabilities
with respect to, such claim, (2) is reasonably contesting such claim in good
faith, by appropriate proceedings, and (3) has taken such action (including the
posting of a bond, deposit or other security) as may be necessary to prevent any
action to foreclose a lien against or attachment of the property of the
Indemnified Party for payment of such claim, the Indemnified Party shall not pay
or settle any such claim. Notwithstanding compliance by the Indemnitor with the
preceding sentence, the Indemnified Party shall have the right to pay or settle
any such claim, provided that in such event it shall waive any right to
indemnity therefor by the Indemnitor for such claim. If, within thirty (30) days
after the receipt of the Indemnified Party's notice of a claim of indemnity
hereunder, the Indemnitor does not notify the Indemnified Party that it elects,
at Indemnitor's cost and expense, to undertake the defense thereof and assume
full responsibility for all indemnified liabilities with respect thereto, or
gives such notice and thereafter fails to contest such claim in good faith or to
prevent action to foreclose a lien against or attachment of the Indemnified
Party's property as contemplated above, the Indemnified Party shall have the
right to contest, settle and/or compromise the claim and, to the extent the
actions, if any, taken by the Indemnified Party in settling or compromising such
claim are reasonable and in good faith, the Indemnified Party shall not thereby
waive any right to indemnity therefor pursuant to this Agreement.

     (a)  Termination of Agreement.  This Agreement and the transactions
          ------------------------
contemplated hereby may be terminated at any time prior to the Closing:

          (1)  By mutual written consent of Seller and Buyer; or

          (2)  If the Closing has not occurred by the close of business on March
     31, 2000, then (i) by Seller if any condition specified in Section 9.1 has
     not been satisfied on or before such close of business, and shall not
     theretofore have been waived by Seller, or (ii) by Buyer if any condition
     specified in Section 9.2 has not been satisfied on or before such close of
     business, and shall not theretofore have been waived by Buyer, or if the
     transactions provided for under this Agreement have not been approved by
     Seller's shareholders and such condition has not been waived by Seller as
     provided in Section 9.1(g); provided, in each case, that the failure to
     consummate the transactions contemplated hereby on or before such date did
     not result from the failure by the party or parties seeking termination of
     this Agreement to fulfill any undertaking or commitment provided for herein
     on the part of such party or parties that is required to be fulfilled on or
     prior to Closing.

     (b)  Effect of Termination.  Without limiting Seller's and Buyer's

respective remedies and rights in regard to the Deposit under Section 14.2, in
the event of termination of this Agreement by Seller, on the one hand, or Buyer,
on the other hand, pursuant to Section 14. l(a), written notice thereof shall

parties hereto, and this Agreement shall thereupon terminate; provided, however,
that following such termination Buyer will continue to be bound by its
obligations set forth in Sections 5.1, 5.2 and 5.4. If this Agreement is
terminated as provided herein all filings,

     Section 14.2   Remedies.
                    --------

     (a)  Seller's Remedies.  Notwithstanding anything herein provided to the
          -----------------
contrary, upon the failure by Buyer to satisfy the conditions to Closing or the
Closing obligations, as the case may be, set forth in (i) item (1) of clause (a)
of Section 9.1 on account of breaches of the representations and warranties made
by Buyer on and as of the date of this Agreement, (ii) item (2) of clause (a) of
Section 9.1, (iii) clause (b) of Section 9.1 on account of breaches of the
representations and warranties made by Buyer on and as of the date of this

this Agreement and, without waiving or releasing Buyer's obligations under
Sections 5.1, 5.2 and 5.4, be paid the Deposit, together with all interest and
other amounts earned thereon as liquidated damages, as Seller's sole and
exclusive remedy for such failure, all other remedies being expressly waived by
Seller. Seller and Buyer agree upon the Deposit amount together with all
interest and other amounts earned thereon, as liquidated damages due to the
difficulty and inconvenience of measuring actual damages and the uncertainty
thereof, and Seller and Buyer agree that such amount is a reasonable estimate of
Seller's loss in the event of any such failure by Buyer.

     (b)  Buyer's Remedies.  Notwithstanding anything herein provided to the
          ----------------
contrary, upon failure of the Seller to satisfy the conditions to Closing or the
Closing obligations, as the case may be, set forth in (i) item (1) of clause
(a) of Section 9.2 on account of breaches of the representations and warranties
made by Seller on and as of the date of this Agreement, (ii) item (2) of clause
(a) of Section 9.2, (iii) clause (b) of Section 9.2 on account of breaches of
the representations and warranties made by Seller on and as of the date of this
Agreement or the failure by Seller to satisfy the condition set forth in item
(2) of clause (a) of Section 9.2, (iv) clause (e) of Section 9.2, or (v) clauses
(a), (d) or (e) of Section 10.2 on or prior to the Closing Date, Buyer, at its
sole option, may (i) enforce specific performance of this Agreement or (ii)
terminate this Agreement and receive back the Deposit, together with all
interest and other amounts earned thereon, as Buyer's sole and exclusive remedy
for such failure, all other remedies being expressly waived by Buyer.

     Section 14.3    Break-Up Fee.  If, as of the Closing Date, Seller has
                     ------------
failed to obtain approval of this Agreement (and the transactions contemplated
hereby) by the shareholders of Seller as required by Section 9.1(g) and this
Agreement is thereafter terminated, Seller shall promptly (but in no event later
than one business day after the occurrence of such event) pay to Buyer a fee in
the amount of $1,500,000 and receive back the Deposit, together with all
interest and other amounts earned thereon, which amounts shall be payable by
wire transfer in immediately available funds to an account designated by Buyer.
The parties hereto agree and

                                      -46-
<PAGE>

acknowledge that the $1,500,000 break-up fee payable pursuant to this Section
14.3 is not a penalty, and represents the parties' efforts to reasonably
estimate a fair compensation for the expenses that might be suffered by Buyer in
the event the transactions contemplated by this Agreement shall not be
consummated for the above reason.

                       EXCHANGE AND FINANCING AGREEMENT

     This Agreement is made as of October 14, 1999 among Carbon Energy
Corporation ("Carbon"), a Colorado corporation, CEC Resources Ltd. ("CEC
Canada"), an Alberta corporation, and Yorktown Energy Partners III, L.P.
("Yorktown").

                                    Recitals

     A. CEC Canada has entered into a Stock Purchase Agreement dated August 11,
1999 (as it may be amended from time to time, called the "Stock Purchase
Agreement") with Bonneville Pacific Corporation ("Bonneville Pacific"). The
Stock Purchase Agreement provides for the purchase by CEC Canada from Bonneville
Pacific of all outstanding shares of Bonneville Fuels Corporation ("BFC") for
$24,000,000 in cash, subject to certain adjustments. After this transaction, BFC
will continue to have outstanding certain indebtedness.

     B. The parties desire that the purchase of BFC stock under the Stock
Purchase Agreement be completed by Carbon which is a corporation organized under
the laws of a state in the United States and which has its principal executive
offices in the United States. The Stock Purchase Agreement permits the
assignment of rights and obligations of CEC Canada under the Stock Purchase
Agreement to Carbon as an affiliate of Yorktown.

     C. Yorktown has committed to purchase equity of Carbon for $24,750,000 in
order to provide equity financing for the total purchase price of the BFC shares
under the Stock Purchase Agreement.

     D. All parties to this Agreement require that, in connection with the
assignment of the Stock Purchase Agreement to Carbon and as part of an overall
plan to contribute cash, securities and other property by CEC Canada, Yorktown
and shareholders of CEC Canada to Carbon, Carbon shall make an offer to all
shareholders of CEC Canada to exchange one share of Carbon for each outstanding
share of CEC Canada.

     E. The Boards of Directors of CEC Canada and Carbon have unanimously
approved of the making of the exchange offer described in paragraph D above and
later in this Agreement. The Board of Directors of CEC Canada has also resolved
to recommend that the holders of shares of CEC Canada tender their shares
pursuant to that exchange offer.

                                   Agreement

     In consideration of the mutual promises and covenants contained in this
Agreement, the parties, intending to be legally bound, agree as follows:


                                   Article 1

                         Articles and Bylaws of Carbon

     The parties concur and approve of the Articles of Incorporation of Carbon
and Bylaws of Carbon as currently in effect, subject to any changes to be made
in the future.


                                   Article 2

                 Authorization and Sale of Carbon Common Stock

     2.1  Authorization and Sale of Shares.
          --------------------------------

     Carbon shall authorize the sale and issuance of 4,500,000 shares of its
common stock to Yorktown.  Subject to the terms and conditions of this
Agreement, Carbon shall issue and sell to Yorktown, and Yorktown shall purchase
from Carbon, 4,500,000 shares of Carbon common stock at a total purchase price
of $24,750,000 in cash, which is $5.50 per share.

     2.2  Closing for Shares.
          ------------------

     The closing of the purchase and sale of the Carbon common stock to Yorktown
as provided in Section 2.1 shall be held at a date, time and place mutually
agreeable to all parties to this Agreement but in any event no later than the
closing of the purchase of BFC stock under the Stock Purchase Agreement (the
"BFC Closing").  At the closing for the sale of Carbon shares as provided in
Section 2.1, Carbon shall deliver to Yorktown a certificate or certificates,
registered in Yorktown's name, representing 4,500,000 shares, free and clear of
any liens, security interests or encumbrances (other than any transfer
restrictions imposed by securities laws); and at that closing Yorktown shall pay
to Carbon the purchase price of $24,750,000 in immediately available funds by
wire transfer per instructions of Carbon.

     2.3  Use of Proceeds.
          ---------------

     The proceeds of the sale of shares to Yorktown as provided in this
Agreement shall be used for the purchase of BFC shares under the Stock Purchase
Agreement, and any remaining proceeds after that purchase shall be added to and
be part of the working capital of Carbon.

                     Assignment of Stock Purchase Agreement

     3.1  Assignment.
          ----------

     On a date mutually agreed upon by all parties to this Agreement but in any
event immediately prior to the BFC Closing, CEC Canada shall assign all rights
and obligations of CEC Canada under the Stock Purchase Agreement to Carbon,
including the right to purchase all outstanding BFC shares.  CEC Canada shall
cause prior notice of this assignment to be given to Bonneville Pacific under
the terms of the Stock Purchase Agreement.  It is further understood that, in
accordance with the terms of the Stock Purchase Agreement, CEC Canada shall
remain fully liable for all of its obligations under the Stock Purchase
Agreement.

     3.2  Assumption; Reimbursement of Deposit.
          ------------------------------------

     Carbon, upon receipt of that assignment of the Stock Purchase Agreement,
shall perform and comply with all obligations and terms applicable to CEC Canada
under the Stock Purchase Agreement, as if Carbon were named as the Buyer in the
Stock Purchase Agreement instead of CEC Canada.  Also, upon receipt of that
assignment of the Stock Purchase Agreement, Carbon shall pay $1,200,000 to CEC
Canada as reimbursement of the deposit made by CEC Canada on the purchase price
under the Stock Purchase Agreement.

     3.3  Amendments.
          ----------

     Neither CEC Canada nor Carbon will make any amendment to the Stock Purchase
Agreement or grant any waiver under the Stock Purchase Agreement without the
permission and consent of the other parties to this Agreement, including
Yorktown.


                                   Article 4

                                 Exchange Offer

     4.1  The Offer.
          ---------

     Carbon shall, and Yorktown and CEC Canada shall cause Carbon to, make an
offer to all holders of shares of CEC Canada to exchange one share of common
stock of Carbon for each outstanding share of CEC Canada (the "Exchange Offer")
as promptly as reasonably practicable after the BFC Closing.  The obligation of
Carbon to make the Exchange Offer is subject only to the assignment of the Stock
Purchase Agreement by CEC Canada to Carbon as provided above and the
consummation of the BFC Closing.  In order for any specific term to be included
in the Exchange Offer, the term must be approved by Yorktown, CEC Canada and
Carbon, whose approval shall not be unreasonably withheld.  Promptly after the
expiration of any

                                       3
<PAGE>

withdrawal rights for tendered shares in the Exchange Offer or the expiration of
the Exchange Offer, as the case may be, Carbon shall exchange its shares for all
shares of CEC Canada validly tendered in the Exchange Offer and not withdrawn.

     4.2  Compliance With Applicable Law.
          ------------------------------

     Carbon shall take, and CEC Canada and Yorktown shall cause Carbon to take,
all necessary steps to comply with applicable law in making the Exchange Offer,
including without limitation (a) filing with the Securities and Exchange
Commission ("SEC") a registration statement on Form S-4 (together with any
amendments and supplements, called the "Registration Statement") under the
Securities Act of 1933 (the "Securities Act"), (b) filing with the SEC a tender
offer statement on Schedule 14D-1 (together with all amendments and supplements,
called the "Schedule 14D-1") with respect to the Exchange Offer, and (c) filing
all documents required to obtain any permits and approvals, if any, required to
carry out the transactions contemplated by this Agreement under any applicable
Canadian laws or state securities laws and will use its best efforts to obtain
such permits and approvals.  The Registration Statement and Schedule 14D-1 shall
include summary advertisements, letters of transmittal and such other documents
as necessary to make the Exchange Offer (the Registration Statement, Schedule
14D-1 and other documents, together with all supplements and amendments, are
called collectively the "Offer Documents").

     4.3  CEC Canada Approval.
          -------------------

     CEC Canada hereby approves of the Exchange Offer and represents that the
Board has unanimously determined that this Agreement and the transactions
contemplated by this Agreement, including the Exchange Offer, are fair to and in
the best interests of the shareholders of CEC Canada.  The Board of Directors of
CEC Canada shall recommend that the shareholders of CEC Canada accept the
Exchange Offer, and CEC Canada consents to the inclusion in the Registration
Statement and other Offer Documents of the recommendation of the Board of
Directors as described above.  Also CEC Canada represents that it has been
advised by each of its directors and executive officers that each of them
intends either to tender or cause to be tendered all shares of CEC Canada
beneficially owned by them in the Exchange Offer.  As soon as reasonably
practical and no later than the date of commencement of the Exchange Offer, CEC
Canada shall file with the SEC a Solicitation/ Recommendation Statement on
Schedule 14D-9 (which, together with all amendments and supplements, is called
the "Schedule 14D-9") containing the recommendation of the Board described in
this Section and shall disseminate the Schedule 14D-9 to the extent required by
rules of the SEC under the Securities Exchange Act of 1934 (the "Exchange Act")
and any other applicable federal securities laws.  CEC Canada agrees to correct
promptly any information provided by it for use in the Schedule 14D-9 which
shall have become false or misleading and to take all steps necessary to cause
the Schedule 14D-9 as so corrected to be filed with

                                       4
<PAGE>

the SEC and disseminated to holders of shares of CEC Canada to the extent
required by applicable federal securities laws.

     4.4  Shareholder Information.
          -----------------------

     CEC Canada shall promptly furnish to Carbon mailing labels containing the
name and addresses of all record holders of shares of CEC Canada and with
security position listings of all shares held in stock depositories, each as of
a recent date, together with all other available listings and computer files
containing names, addresses and security position listings of record holders and
beneficial owners of shares of CEC Canada.  CEC Canada shall furnish Carbon with
such additional information, including without limitation, updated listings and
computer files of shareholders, mailing labels and security position listings
and such other assistance as Carbon may reasonably request for the Exchange
Offer.  Carbon shall, subject to the requirements of applicable law and except
as necessary to disseminate the Exchange Offer and any Offer Documents, hold in
confidence the information contained in those labels, listings and files and
shall use such information only in connection with the Exchange Offer.

has the capacity to protect its own interests.

     It is acquiring Carbon shares as provided in Article 2 for investment for
its own account, not as a nominee or agent, and not with the view to, or for
resale in connection with, any distribution thereof.  It understands that Carbon
shares have not been, and will not be registered, under the Securities Act by
reason of a specific exemption from the registration provisions of the
Securities Act, the availability of which depends upon, among other things, the
bona fide nature of the investment intent and the accuracy of Yorktown's
representations as expressed in this Section.

     Yorktown has had an opportunity to discuss Carbon's business, management
and financial affairs with Carbon's management and has had the opportunity to
review Carbon's existing and proposed properties and operations.  It has also
had an opportunity to ask questions of officers of Carbon, which questions were
answered to its satisfaction.

    asserted or arising before or after the completion of the Exchange Offer,
    survive the Exchange Offer and shall continue in full force and effect.
    Nothing contained in this paragraph 10.1(h)(i) shall be deemed to preclude
    the liquidation, consolidation or merger of CEC Canada, in which case all of
    such rights to indemnification and limitations on liability shall be deemed
    to survive and continue as contractual rights notwithstanding any such
    liquidation or consolidation or merger; provided, however, that in the event
                                            --------  -------
    of liquidation or sale of substantially all of the assets of CEC Canada,
    Carbon shall guarantee, to the extent of the net asset value of Carbon as of
    the completion of the Exchange Offer, the indemnification obligations of CEC
    Canada to the extent of indemnification obligations of Carbon described
    above.

          (ii) any Indemnified Party wishing to claim indemnification under
    paragraph 10.1(h)(i), upon learning of any such claim, action, suit,
    proceeding

                                      17
<PAGE>

    or investigation, shall promptly notify Carbon thereof, but the failure to
    so notify shall not relieve Carbon of any liability it may have to such
    Indemnified Party. In the event of any such claim, action, suit, proceeding
    or investigation (whether arising before or after completion of the Exchange
    Offer), (A) Carbon shall have the right to assume the defense thereof and
    Carbon shall not be liable to any Indemnified Party for any legal expenses
    of other counsel or any other expenses subsequently incurred by such
    Indemnified Party in connection with the defense thereof, except that if
    Carbon elects not to assume such defense or counsel for the Indemnified
    Party advises that there are issues which raise conflicts of interest
    between Carbon and the Indemnified Party, the Indemnified Party may retain
    counsel satisfactory to them, and Carbon shall pay the reasonable fees and
    expenses of such counsel for the Indemnified Party promptly as statements
    therefor are received; provided, however, that Carbon shall be obligated
                           --------  -------
    pursuant to this subparagraph (ii) to pay for only one firm of counsel for
    all Indemnified Parties in any jurisdiction unless the use of one counsel
    for such Indemnified Parties would present such counsel with a conflict of
    interest and (B) such Indemnified Party shall cooperate in the defense of
    any such matter. In any event, Carbon shall not be liable for the settlement
    of any claim, action, suit, proceeding or investigation unless Carbon
    consents to the settlement, which consent shall not be unreasonably
    withheld.

          (iii)  if Carbon or any of its successors or assigns (A) shall
    consolidate with or merge into any other corporation or entity and shall not
    be the continuing or surviving corporation or entity of such consolidation
    or merger or (B) shall transfer all or substantially all of its properties
    and assets to any individual, corporation or other entity, then and in each
    such case, proper provision shall be made so that the successors and assigns
    of Carbon shall assume the obligations set forth in this paragraph 10.1(h).

          (iv)  the provisions of this paragraph 10.1(h) are intended to be for
    the benefit of, and shall be enforceable by, each Indemnified Party and his
    or her heirs and representatives.
