                               PROSPECTUS SUMMARY

procedures again prior to the expiration of the exchange offer.

                                       3



   Our offer may be terminated if any court or governmental authority issues an
order restraining, enjoining or otherwise prohibiting consummation of the
exchange offer.

 Procedures For Tendering Your Shares Of CEC Common Stock

   If you hold certificates for shares of CEC common stock, you must complete
and sign the letter of transmittal designating the number of CEC shares you
wish to tender and return the letter with your stock certificates and any other
documents required by the letter of transmittal, by registered mail, return
receipt requested, so that it is received by the exchange agent at one of the
addresses listed in "The Exchange Offer--The Exchange Agent" before the
expiration of the exchange offer on           , 1999.

   If you hold shares of CEC common stock through a broker, you should receive
instructions from your broker on how to participate. In this situation, you do
not need to complete the letter of transmittal. Please contact your broker
directly if you have not yet received instructions. Some financial institutions
may also effect tenders by book-entry transfer through The Depository Trust
Company.

   If you hold certificates for shares of CEC common stock or if you hold CEC
shares through a broker, you may also comply with the procedures for guaranteed
delivery.

 Guaranteed Delivery Procedures

   Holders of CEC common stock who wish to tender their shares and whose shares
are not immediately available or who cannot deliver their certificates for CEC
common stock, the letter of transmittal or any other documentation required by
the letter of transmittal to the exchange agent prior to the expiration date
must tender their shares of CEC common stock according to the guaranteed
delivery procedures described in "The Exchange Offer--Guaranteed Delivery
Procedures."

 Acceptance of CEC Common Stock and Delivery of Carbon Common Stock

   Subject to the satisfaction or waiver of the conditions to the exchange
offer, we will accept for exchange any and all shares of CEC common stock that
are properly tendered in the exchange offer and not withdrawn prior to the
expiration date. The Carbon common stock to be delivered in exchange for your
shares of CEC common stock will be delivered promptly following the expiration
of our offer.

 No Dissenters' Rights

   No dissenters' rights are available to shareholders of CEC in connection
with the exchange offer.

 Exchange Agent

   Harris Trust and Savings Bank is serving as the exchange agent in connection
with our exchange offer.

 Possible Effects of the Exchange Offer

   The exchange of shares of CEC common stock in the exchange offer will reduce
the number of holders of CEC common stock and the number of shares of CEC
common stock that might otherwise trade publicly. Depending on the number of
shares of CEC common stock exchanged, the liquidity and market value of the
remaining shares of CEC common stock could be adversely affected. CEC's common
stock is listed on the American Stock Exchange ("AMEX"). Depending on the
number of shares of CEC common stock exchanged pursuant to the exchange offer,
CEC common stock may no longer meet the requirements of the AMEX for continued
listing. Because holders of approximately 40% of the outstanding shares of CEC
have stated their

                                       4


intentions to accept the exchange offer, we anticipate that CEC common stock
will be delisted from the AMEX. If the shares of CEC common stock were to be
delisted from the AMEX, the market for such shares could be adversely affected.
It is possible that such shares might be traded on other securities markets.
The extent of the public market for the shares of CEC common stock would,
however, depend upon the number of holders and/or the aggregate market value of
such shares remaining at that time, the interest in maintaining a market in
such shares on the part of securities firms and the possible termination of
registration of CEC common stock under the Securities Exchange Act of 1934
("Exchange Act").

   CEC's common stock is currently registered under the Exchange Act. Such
registration may be terminated by CEC upon application to the Securities and
Exchange Commission ("SEC") if the outstanding shares of CEC common stock are
not listed upon a national securities exchange and if there are fewer than 300
holders of record of such shares. Termination of registration of the CEC common
stock under the Exchange Act would reduce the information required to be
furnished by CEC to its shareholders and to the SEC and would make certain
provisions of the Exchange Act, such as the filing of periodic SEC reports, the
requirement of furnishing a proxy statement pursuant to Section 14(a), and the
short-swing profit recovery provisions of Section 16(b), no longer applicable
to CEC shares.

Background of the Exchange Offer/Exchange and Financing Agreement

   The information in this section regarding the deliberations of CEC's Board
of Directors and the actions of CEC's management and legal and financial
advisors is based on information furnished by CEC.

   CEC and Carbon believe there are attractive opportunities available for
acquisitions of oil and gas properties and exploration and production in both
the United States and Canada as a result of improving oil and gas prices, lower
exploration and production costs, the divestiture of non-core properties by
major oil companies and large independent oil companies and consolidation
within the oil and gas industry. CEC's position as a small independent public
oil and gas company limits its potential for growth unless steps are taken to
increase its size and the value of its oil and gas reserves.

   In early May, 1999, CEC learned that Bonneville Pacific Corporation ("BPC")
would be selling the stock of its Denver based 100% owned subsidiary, BFC.
During May, June, July and early August, 1999, CEC participated in a sale
process conducted by BPC for the sale of BFC. During that period, CEC conducted
due diligence concerning BFC and its properties, submitted various offers for
BFC and submitted comments on the form of the stock purchase agreement for the
acquisition of BFC prepared by BPC.

   During this period, CEC also conducted discussions with Yorktown Partners
LLC (an energy investment firm which is the manager of Yorktown Energy Partners
III, L.P.) relating to the financing of the acquisition of BFC by Yorktown.
These discussions resulted in a determination that Yorktown would provide
equity financing through a United States corporation. As a result, Carbon was
formed in September, 1999.

   On August 11, 1999, CEC and BPC signed the BFC stock purchase agreement.
Under the BFC stock purchase agreement, CEC agreed to purchase all BFC
outstanding stock from BPC at a price of $23,857,951 in cash, subject to
certain adjustments, with debt less working capital of approximately $6,500,000
remaining at BFC (referred to as "net debt"). On October 14, 1999, Carbon, CEC
and Yorktown signed the exchange and financing agreement providing for an
assignment of the BFC stock purchase agreement to Carbon, the purchase of
common stock of Carbon by Yorktown for $24,750,000, and the exchange offer made
by this prospectus. This purchase of Carbon stock by Yorktown was at a price of
$5.50 per share. On October 29, 1999, Carbon completed the purchase of BFC.

   The exchange offer gives each shareholder of CEC the opportunity to become a
shareholder in Carbon which will be a substantially larger oil and gas company
than CEC alone. Carbon owns BFC, and, it is anticipated

                                       5


Carbon will own more than a majority of CEC. The formation of Carbon results
from Yorktown's desire for making its investment in a United States corporation
and unfavorable tax consequences that would have resulted by reincorporating
CEC from an Alberta corporation with Canadian assets into a U.S. corporation
with both Canadian and U.S. assets. For a more complete description of the
background surrounding the purchase of BFC, the formation of Carbon and the
making of the exchange offer, see "The Exchange Offer--Background of the
Exchange Offer/Exchange Agreement".

Recommendation of the Board of Directors of CEC

   CEC's Board of Directors believes that the terms of the exchange offer are
fair to and in the best interest of CEC and its shareholders. In reaching its
decision, CEC's Board considered a number of factors, including the following:

  .  The acquisition of BFC and the exchange offer would result in Carbon
     being led by a highly regarded management team with a strong track
     record in the oil and gas industry.

  .  The structure of the transaction with CEC's current shareholders having
     the opportunity to participate in the future value of both BFC and CEC
     as part of Carbon by accepting the exchange offer.

  .  Reasons for the acquisition of BFC, including potential growth, the
     nature of BFC's properties and cost savings that may be realized in the
     operation of BFC by Carbon.

  .  The terms of the BFC stock purchase agreement, including the parties'
     representations, warranties and covenants and the conditions to their
     respective obligations.

  .  United States and Canadian tax consequences of the transaction.

  .  The requirement of Yorktown that its equity financing be made through a
     United States corporation.

  .  The valuation of CEC involved in the equity financing made by Yorktown;
     alternatives to Yorktown's proposal that had been considered or sought
     in the past; a previous search by CEC for a buyer, which was conducted
     prior to Patrick R. McDonald's becoming a significant shareholder, and
     resulted in no offers.

  .  Valuation methods applicable to CEC, including discounted cash flow,
     multiple of cash flow and public stock market values.

  .  Current financial market conditions and historical market prices,
     volatility and trading information with respect to CEC's common stock.

  .  The likelihood of continuing consolidation in the energy industry and
     increased competition from larger, well-financed companies.

  .  The reports from CEC's management as to the results of its due diligence
     investigation of BFC and its business.

Intentions of the Board of Directors of CEC

   Directors and executive officers of CEC who hold, in the aggregate, 580,346
shares of outstanding CEC common stock, representing approximately 38.1% of
CEC's outstanding shares, have stated their intention to accept our stock in
the exchange offer.

United States Federal Income Tax Consequences

   Subject to a number of qualifications and conditions, and to the accuracy of
certain factual representations made by Carbon and CEC, Holland & Hart LLP, tax
counsel to CEC, has rendered an opinion, that for U.S. federal income tax
purposes, (1) the transactions contemplated by the exchange offer should
constitute a tax-free B reorganization, assuming that Carbon acquires at least
80% of the outstanding stock of CEC pursuant to the

                                       6


exchange offer, and (2) the transactions contemplated by the exchange offer
likely constitute part of a tax-free Section 351 transaction even if the
transactions contemplated by the exchange offer do not qualify as a B
reorganization. See "United States Federal Income Tax Consequences." Tax
counsel's opinion is not a substitute for each individual CEC shareholder's
review of the tax consequences of the exchange by its own advisor. See "Risk
Factors." Non-U.S. shareholders who receive Carbon stock in the exchange may be
subject to U.S. tax with respect to their investment in Carbon common stock or
may otherwise be affected by U.S. tax law. The summary of U.S. federal income
tax consequences of the exchange set forth in "United States Federal Income Tax
Consequences" does not cover all U.S. federal income tax aspects of the
exchange and may not be applicable to every CEC shareholder exchanging shares.
For these reasons, each CEC shareholder participating in the exchange is urged
and expected to consult with and rely on its tax advisor regarding the U.S.
federal income tax aspects of the exchange.

Canadian Federal Income Tax Consequences

   Subject to the specific exceptions referred to under "Canadian Federal
Income Tax Consequences" below, the exchange of CEC common stock for Carbon
common stock will generally be tax-free to non-Canadian holders of CEC common
stock for Canadian federal income tax purposes.

   Canadian holders of CEC common stock will not benefit from tax-free
treatment for Canadian federal income tax purposes and will have to recognize a
gain or loss equal to the difference between the fair market value of the
Carbon common stock and the aggregate of the adjusted cost base of the CEC
common stock and any reasonable costs of disposition.

   The tax considerations to you resulting from your individual position and
the exchange may be complex. Carbon recommends that you read carefully the
discussion under "Canadian Federal Income Tax Consequences" and consult with
your own advisors as to the Canadian federal, provincial or territorial tax
consequences.

   An opinion on these Canadian tax matters has been rendered by Bennett Jones,
counsel to CEC. Their opinion is subject to the assumptions and qualifications
set forth under "Canadian Federal Income Tax Consequences."

Accounting Treatment

   We will account for the exchange offer as a purchase of CEC in accordance
with generally accepted accounting principles. For a discussion of the
application of purchase accounting to this transaction, see "The Exchange
Offer--Accounting Treatment."

Comparison of Shareholders' Rights

   CEC shareholders who accept our exchange offer will become shareholders of
Carbon and be governed by our articles of incorporation and bylaws and the
Colorado Business Corporation Act. There are a number of differences between
our articles of incorporation and bylaws and the Colorado Business Corporation
Act and the articles of association and bylaws of CEC and the Alberta Business
Corporations Act. These differences are discussed under "Comparison Of
Shareholders' Rights."

Interests of Certain Persons in the Exchange Offer

   In considering whether to accept our offer, you should consider the
interests various executive officers and directors have in the exchange offer.
Patrick R. McDonald, President of CEC, and Kevin Struzeski, Chief Financial
Officer-Treasurer of CEC, have entered into employment agreements with Carbon.
In addition, Mr. McDonald and Mr. Struzeski have been granted restricted stock
of Carbon and stock options to acquire shares of

                                       7


its common stock. Mr. McDonald, Mr. Struzeski and other officers of CEC are to
receive bonuses from CEC upon completion of the exchange offer if 50% or more
of the CEC shares are exchanged for Carbon shares. The employment agreements
replace employment agreements with CEC and were negotiated on an arms'-length
basis with Yorktown. For a description of these interests, see "The Exchange
Offer--Interests of Certain Persons in the Exchange Offer."

Second Step Merger

   After the exchange offer, we may merge CEC with a wholly-owned Canadian
subsidiary of Carbon. In such a merger, shareholders of CEC may receive cash,
shares of our stock, other securities or a combination of some or all of the
foregoing. If CEC common stock is listed on the AMEX on the record date for
determining shareholders entitled to vote on the merger, no dissenters' rights
will be available to CEC's shareholders in connection with the merger. In
contrast, if CEC common stock is not listed on the AMEX on such record date,
CEC shareholders will be entitled to dissenters' rights in connection with the
merger. The continued listing of CEC common stock will depend upon the effect
of the exchange offer on the shares of CEC held by persons other than Carbon,
and it is currently contemplated that the CEC shares will be delisted from
AMEX.

   We do not intend to do a second step merger if it would result in adverse
United States income tax consequences to CEC shareholders who accepted our
exchange offer. We will not engage in a second step merger without informing,
and receiving approval from, our tax counsel.

Comparative Per Share Data

   The table below sets forth, for the periods indicated, the following:

 .  the pro forma basic and diluted net income (loss) and book value per share
   of Carbon common stock after giving effect to the closing of the exchange
   offer and assuming all shareholders of CEC accept our offer; and

 .  the historical basic and diluted net income (loss) and book value per share
   of CEC common stock which is the same as the equivalent pro forma per share
   data because the exchange offer is on a one-to-one basis.

   Neither we nor CEC have declared or paid any cash dividends on our common
stock. We currently expect to retain any future earnings for use in the
operation and expansion of our business and do not anticipate paying any cash
dividends in the foreseeable future. The information presented in this table
should be read in conjunction with the pro forma consolidated condensed
financial information and the separate financial statements of Carbon and CEC
included elsewhere in this prospectus.

CEC Per Share Market Information

   The common stock of CEC has traded on the American Stock Exchange regular
list since July 6, 1995. The common stock initially began trading on the
American Stock Exchange Emerging Companies Marketplace on March 24, 1995 about
one month after it was divested by Columbus Energy Corp. to its shareholders by
a rights offering. The reported high and low sales prices in U.S. dollars for
the periods ending below were as follows:

                                 RISK FACTORS

   You should carefully consider the following risk factors and all other
information contained in this prospectus before you decide to accept or reject
the exchange offer. The risks and uncertainties we describe below are not the
only risks we face. You should consider all of these risk factors along with
the other information contained in the documents to which we have referred
you.

   If any of the adverse events described in the following risk factors
actually occur or we do not accomplish necessary events described in the risk
factors, our business, financial condition and operating results could be
materially and adversely affected, the trading price of our common stock could
decline and you could lose all or part of your investment.

 There are a number of risks associated with the purchase of BFC and the
 exchange offer:

We may not be able to successfully integrate BFC and CEC.

   Carbon acquired BFC in October, 1999. The integration and consolidation of
the assets and operations of Carbon, BFC and CEC after the exchange offer will
present significant management challenges for Carbon. Carbon cannot assure you
that it will be able to successfully integrate the Carbon, BFC and CEC
business operations or that the combined company will realize any of the
anticipated benefits of the transactions.

You or Carbon could incur United States income taxes.

   As described in the section of this prospectus entitled "United States
Federal Income Tax Consequences," no ruling will be requested from the IRS
regarding the United States income tax aspects of the exchange. Although
Holland and Hart LLP, tax counsel for Carbon, has rendered the opinion set
forth in the section of this prospectus entitled "United States Federal Income
Tax Consequences," the opinion is limited in scope, is subject to a number of
qualifications, limitations and conditions and is subject to the accuracy of
certain factual representations made by Carbon. As discussed in "United States
Federal Income Tax Consequences," holders of more than 80% of CEC shares must
participate in the exchange in order for the exchange to constitute a tax-free
B reorganization. If holders of less than 80% of the CEC shares accept the
exchange offer, tax-free treatment is less certain, although it will still be
likely that the exchange will qualify as a tax-free transaction. Moreover, an
opinion of counsel is not binding on the IRS, and the IRS may successfully
take a position contrary to tax counsel's opinion. For these reasons, each CEC
shareholder participating in the exchange is urged and expected to consult
with and rely on its tax advisor regarding the exchange.

Shareholders of CEC who reside in Canada may incur Canadian income taxes by
accepting the exchange offer.

   Canadian holders of CEC common stock will not benefit from tax-free
treatment for Canadian federal income tax purposes and will have to recognize
a gain or loss equal to the difference between the fair market value of the
Carbon common stock and the aggregate of the adjusted cost base of the CEC
common stock and any reasonable costs of disposition.

   The tax considerations to you resulting from your individual position and
the exchange may be complex. You should read carefully the discussion under
"Canadian Federal Income Tax Consequences" and consult with your own advisors
as to the Canadian federal, provincial or territorial tax consequences.

Yorktown is Carbon's controlling stockholder.

   After the exchange offer, Yorktown will own 74% of Carbon's common stock or
more if some of CEC's shareholders do not accept the exchange offer.
Accordingly, Yorktown will be able to determine virtually all matters
submitted for shareholder approval. The nomination and election of Carbon's
directors are subject to the terms of the exchange and financing agreement
among Carbon, CEC and Yorktown. Upon termination of the

                                      12


provisions of the exchange and financing agreement relating to the nomination
and election of directors, Yorktown will be able to control the election of
directors and to determine the corporate and management policies of Carbon.
See "The Exchange Offer--Description of Exchange Agreement."

No prior market for Carbon shares exists, and the market price for Carbon
shares may decrease after the exchange offer.

   Prior to the exchange offer, there has been no public market for our
shares. CEC shares have been traded on the AMEX, but the market was very thin
and little trading occurred. There can be no assurance that an active trading
market for our common stock will develop or be sustained. There is also
uncertainty as to the prices at which our shares will trade. The possibility
exists that the trading price for our shares may be lower than the prior
market prices for CEC shares. Also, the price of CEC shares may decrease after
the exchange offer if holders with a relatively large number of shares decide
to sell the shares immediately or shortly after the exchange offer.

CEC shareholders will not have a readily available market for CEC shares after
the exchange offer.

   We anticipate that most CEC shareholders will tender their shares in
exchange for Carbon shares. We therefore contemplate that CEC shares will be
delisted from the AMEX and may not be traded or quoted on any public market.

We depend heavily on our key personnel.

   We depend to a substantial extent on the expertise and services of our
senior management personnel and upon the expertise and services of Patrick R.
McDonald, who is our President and Chief Executive Officer and one of our
directors. The loss of Mr. McDonald's or of any of our other senior management
personnel's services could have a material adverse effect on us. We do not
maintain key-man life insurance on any of our personnel.

We may be unable to obtain additional financing.

   Due to our plans for active acquisition, development and exploration
programs, we expect to experience substantial capital needs. We expect to be
able to finance our planned acquisition, development and exploration programs
for the next twelve months from cash generated by our operations and from bank
financing. We cannot assure you as to the availability or terms of any
additional financing that may be required or whether financing will continue
to be available under existing or new credit facilities. If sufficient capital
resources are not available to Carbon, its drilling and other activities may
be curtailed.

 There are a number of risks related to our business:

Risks relating to the acquisition of oil and gas properties may affect our
future success.

   CEC has made several recent acquisitions, and Carbon plans to engage in
future acquisitions of oil and gas properties. The successful acquisition of
producing properties requires an assessment of recoverable reserves, future
oil and gas prices, operating costs, potential environmental and other
liabilities and other factors. Such assessments are necessarily inexact and
their accuracy inherently uncertain. In connection with such an assessment, we
perform a review of the subject properties that we believe to be generally
consistent with industry practices. This usually includes on-site inspections
and the review of reports filed with various regulatory entities. Such a
review, however, will not reveal all existing or potential problems, nor will
it permit a buyer to become sufficiently familiar with the properties to fully
assess their deficiencies and capabilities. Inspections may not always be
performed on every well, and geological, mechanical and environmental problems
are not necessarily observable even when an inspection is undertaken. Although
we perform a review of acquired properties that we believe is consistent with
industry practices, existing or potential environmental problems with
properties may not be discovered until after an acquisition has been
completed. Even when problems are identified, the seller

                                      13


maybe unwilling or unable to provide effective contractual protection against
all or part of these problems. We cannot assure you that any of our
acquisitions of property interests will be successful and, if an acquisition
is unsuccessful, that the failure will not have an adverse effect on our
future results of operations and financial condition.

Carbon's technology systems may not be ready for the Year 2000.

   Carbon has not completed a comprehensive analysis of the operational
problems and costs that would be reasonably likely to result from any failure
of the technology systems of Carbon or of other third parties with which
Carbon has significant relationships to be Year 2000 compliant by January 1,
2000. Carbon has made inquiries of the suppliers and manufacturers of its
computer systems, including equipment supplied by third parties, and it has
been advised that these systems are Year 2000 compliant except in the case of
its property management software, which is currently under review regarding
Year 2000 compliance. We cannot assure you that the Year 2000 issue will not
have a material adverse effect on Carbon's financial condition, results of
operations or cash flows.

Examination of titles is limited prior to drilling.

   Carbon and CEC hold title to their properties pursuant to leases from third
parties or, in the case of CEC, the Crown. We believe that Carbon and CEC have
satisfactory title to their properties. Oil and gas interests are subject to
customary interests and burdens, including overriding royalties and operating
agreements. Their properties may also be subject to liens incident to
operating agreements, as well as minor encumbrances, easements and
restrictions. As is customary in the oil and gas industry, Carbon and CEC do
not regularly investigate title to oil and gas leases acquired as undeveloped
acreage. Rather, Carbon and CEC typically examine title before any drilling or
development is undertaken. Our management believes the methods of title
examination Carbon and CEC have adopted are reasonably calculated to insure
that production from our properties, if obtained, will be readily salable for
our account. Our management is not aware of any material pending or threatened
claims affecting title to Carbon's or CEC's proved acreage. Carbon's and CEC's
producing and non-producing properties are subject to customary royalty
interests, liens for current taxes, and other burdens, none of which, in our
management's opinion, materially interferes with the use of or adversely
affects the value of such properties.

Operating hazards are inherent in the oil and gas industry.

   The oil and gas business involves a variety of operating risks including
the following risks:

  .  fire;

  .  explosion;

  .  blow-out;

  .  pipe failure;

  .  casing collapse;

  .  abnormally pressured formations; and

  .  environmental hazards such as oil spills, gas leaks, ruptures and
     discharge of toxic substances.

If any of these events were to occur, we could incur substantial losses due
to:

  .  injury and loss of life;

  .  severe damage to and destruction of property, natural resources and
     equipment;

  .  pollution and other environmental damage;

  .  clean-up responsibilities;

                                      14


  .  regulatory investigation and penalties; and

  .  suspension of operations.

We maintain insurance against some, but not all, potential risks; however,
there can be no assurance that any insurance we obtain will be adequate to
cover all losses or exposure for liability. Furthermore, we cannot predict
whether insurance will continue to be available at premium levels that justify
its purchase. Generally, we have elected not to obtain blow-out insurance when
drilling a well because we have not operated in areas with abnormally high
pressures or with known severe lost circulation problems.

We may not be able to replace existing oil and gas reserves with new oil and
gas reserves.

   In general, the rate of production from oil and natural gas properties
decline as reserves are depleted. The rate of decline depends on reservoir
characteristics. Except to the extent that we conduct successful exploration
and development activities or acquire properties containing proved reserves,
or both, our proved reserves will decline as reserves are produced. Our future
oil and natural gas production is highly dependent upon our ability to
economically find, develop or acquire reserves in commercial quantities. The
business of exploring for or developing reserves is capital intensive. To the
extent cash flow from operations is reduced and external sources of capital
become limited or unavailable, our ability to make the necessary capital
investment to maintain or expand our asset base of oil and natural gas
reserves would be impaired. In addition, there can be no assurance that our
future exploration and development activities will result in additional proved
reserves or that we will be able to drill economical and productive wells.
Furthermore, although our revenues could increase if prevailing prices for oil
and natural gas increase significantly, our finding and development costs
could increase.

We face strong competition in the oil and gas industry.

   We operate in the highly competitive area of oil and natural gas
exploration, acquisition and production. In seeking to acquire desirable
producing properties or new leases for future exploration and in marketing our
oil and natural gas production, as well as in seeking to acquire the equipment
and expertise necessary to operate and develop those properties, we face
intense competition from a large number of independent, technology-driven
companies as well as both major and other independent oil and natural gas
companies. Many of these competitors have financial and other resources
substantially in excess of those available to us. Competitors may be able to
pay more for exploratory prospects and productive oil and natural gas
properties and may be able to define, evaluate, bid for and purchase a greater
number of properties and prospects than our financial or human resources
permit.

Governmental regulation and environmental matters generally affect our
business.

   Oil and natural gas operations are subject to various federal, state and
local government laws and regulations, which may be changed from time to time
in response to economic or political conditions. Matters subject to regulation
include discharge permits for drilling operations, drilling bonds, reports
concerning operations, spacing of wells, utilization and pooling of
properties, environmental protection and taxation. From time to time,
regulatory agencies have imposed price controls and limitations on production
by restricting the rate of flow of oil and natural gas wells below actual
production capacity in order to conserve supplies of oil and natural gas. We
are also subject to changing and extensive tax laws, the effects of which
cannot be predicted. The development, production, handling, storage,
transportation and disposal of oil and natural gas, by-products thereof and
other substances and materials produced or used in connection with oil and
natural gas operations are subject to laws and regulations primarily relating
to protection of human health and the environment. The discharge of oil,
natural gas or pollutants into the air, soil or water may give rise to
significant liabilities on our part to governments and third parties and may
result in the assessment of civil or criminal penalties or require us to incur
substantial costs of remediation. Legal requirements frequently are changed
and subject to interpretation. We are unable to predict the ultimate cost of
compliance with these requirements or the effect of these requirements on our
operations. Existing laws or regulations, as currently interpreted or
reinterpreted in the future, or future laws or regulations could materially
adversely affect our business, results of operations and its financial
condition.

                                      15


When CEC becomes a subsidiary of Carbon, our Canadian operations will be
subject to Canadian government and environmental regulations.

   The petroleum and natural gas industry operates in Canada under federal and
provincial legislation and regulations governing land tenure, royalties,
production rates, environmental protection, exports and other matters.
Canadian federal authorities do not regulate the price of oil and gas in
export trade, but instead rely on market forces to establish these prices. The
quantities of oil and gas which may be removed from the provinces or exported
from Canada is governed by legislation. Producers pay provincial royalties for
production from Crown leases and freehold royalties on freehold leases.
Provincial royalties are subject to a sliding scale which fluctuates with
changes in productivity and prices. The sliding scale formula is designed to
retain funds in the oil and gas industry when commodity prices are low, with
increases in the royalty rates in times of high commodity prices when the
industry's need for royalty rate relief is not as great. The Alberta
government requires that gas royalties be paid on the basis of the Gas
Reference Price (determined monthly on the basis of a weighted average field
price) or on the basis of the producer's Corporate Average Price. This
requirement discourages natural gas price discounting. CEC elected to use the
Gas Reference Price, which Carbon will continue to use. The Alberta government
permits gas gathering and processing costs (based on corporate average capital
costs and deemed operating costs) to be deducted in computing the Crown
royalty. Effective January 1, 1990, the Alberta government revised the Alberta
Royalty Tax Credit formula to a sliding scale, based on oil and gas prices. In
Alberta, certain, smaller, producers of oil or natural gas are entitled to a
credit against the royalties payable to the Crown by virtue of the ARTC
(Alberta Royalty Tax Credit) program. The ARTC program is based on a price-
sensitive formula, and the ARTC rate varies between 75 percent and 25 percent,
depending on commodity prices. The ARTC rate is applied to a maximum of
$2,000,000 of Alberta Crown royalties payable. Crown royalties on production
from producing properties acquired from corporations claiming maximum
entitlement to ARTC will generally not be eligible for ARTC. The ARTC rate is
established quarterly based on the average "par price," as determined by the
Alberta Department of Energy for the previous quarterly period. On December
22, 1997, the Government of Alberta gave notice that they intended to review
the ARTC program with expected changes to take effect prior to 2001. Although
industry consultation has not yet occurred, among the major proposed changes
will be a 10 year limitation on the ability to claim ARTC entitlements from
production from any applicable well.

   The oil and gas industry is also subject to environmental regulation
pursuant to legislation of the Canadian federal and provincial governments.
Environmental legislation provides for restrictions and prohibitions on
releases or emissions of various substances produced in association with
certain oil and gas industry operations and can affect the location of wells
and facilities and the extent to which exploration and development is
permitted. In addition, legislation requires that well and facility sites and
access be abandoned and reclaimed to the satisfaction of provincial
authorities. A breach of any of these regulations may result in the imposition
of fines and penalties, the suspension of operations and potential civil
liability. The Environmental Protection and Enhancement Act imposes
environmental standards and requires compliance with various legislative
criteria (including reporting and monitoring) in Alberta. The Alberta Energy
and Utilities Board, pursuant to its governing legislation, also plays a role
with respect to the regulation of environmental impacts of oil and gas
activities. We believe that CEC is in compliance with applicable environmental
laws and regulations, and that the environmental regulations as presently in
effect will not have a material effect upon our capital expenditures, or our
competitive position in the industry. Consequently, we do not anticipate the
need for any material capital expenditures for environmental control
facilities for the current year. We believe that it is reasonably likely that
the trend in environmental legislation and regulation will continue toward
stricter standards. No assurance can be given as to the future capital
expenditures which may be required for compliance with environmental
regulations which come into force in the future.

Uncertainty of estimates of oil and gas reserves.

   Estimates of our proved oil and gas reserves and the estimated future net
revenues from them are based upon our own estimates or on third party reserve
reports that rely upon various assumptions, including assumptions about oil
and natural gas prices, drilling and operating expenses, capital expenditures,
taxes and availability of funds. The process of estimating oil and natural gas
reserves is complex, requiring significant

                                      16


decisions and assumptions in the evaluation of available geological,
geophysical, engineering and economic data for each reservoir. As a result,
estimates are inherently imprecise. Actual future production, oil and natural
gas prices, revenues, taxes, development expenditures, operating expenses and
quantities of recoverable oil and natural gas reserves may vary substantially
from our estimates or from estimates reflected in the reserve reports of third
parties. Any significant variance in these assumptions could materially affect
the estimated quantity and value of reserves.

   Our properties also may be susceptible to hydrocarbon drainage from
production by other operators on adjacent properties. In addition, our proved
reserves may be subject to downward or upward revision based upon production
history, results of future exploration and development, prevailing oil and
natural gas prices, mechanical difficulties, government regulation and other
factors, many of which are beyond our control.

   Actual production, revenues, taxes, development expenditures and operating
expenses with respect to our reserves likely will vary from the estimates
used, and such variances may be material. The value of future net revenues as
reflected in this prospectus, based on the SEC's required assumptions, should
not be construed as the current market value of the estimated oil and natural
gas reserves attributable to our properties.

   The estimated discounted future net cash flows from proved reserves
generally are based on prices and costs as of the date of the estimate,
whereas actual future prices and costs may be materially higher or lower.
Actual future net cash flows also will be affected by increases in consumption
by oil and natural gas purchasers and changes in governmental regulations or
taxation. The timing of actual future net cash flows from proved reserves, and
thus their actual present value, will be affected by the timing of both
production and expenditures in connection with the development and production
of oil and natural gas properties.

Our production may not be marketable.

   The marketability of our production depends in part upon the availability,
proximity and capacity of natural gas gathering systems, pipelines and
processing facilities. We deliver nearly 100% of the natural gas we produce
through gas gathering systems and gas pipelines that we do not own. Federal
and state regulation of oil and natural gas production and transportation, tax
and energy policies, changes in supply and demand and general economic
conditions all could adversely affect our ability to produce and market our
oil and natural gas. Any dramatic change in market factors could have a
material adverse effect on our business, financial condition and results of
operations.

Our success might be adversely affected by the volatility of oil and gas
prices.

   Our revenues, profitability, future growth and ability to borrow funds or
obtain additional capital, as well as the carrying value of our properties,
will be substantially dependent upon prevailing prices of oil and gas.
Historically, the markets for oil and gas have been volatile, and they are
likely to continue to be volatile in the future. Prices for oil and gas may
fluctuate widely in response to relatively minor changes in the supply of and
demand for oil and gas, market uncertainty and a variety of additional factors
that are beyond our control.

   It is impossible to predict future oil and gas price movements with
certainty. Declines in oil and gas prices may materially adversely affect our
financial condition, liquidity, ability to finance planned capital
expenditures and results of operations. Lower oil and gas prices also may
reduce the amount of oil and gas that we can produce economically.

Oil and gas price hedging and financial hedging arrangements may expose Carbon
to financial loss in some circumstances.

   In order to reduce our exposure to short-term fluctuations in the prices of
oil and gas, we periodically have entered into hedging arrangements. The
hedging arrangements apply to only a portion of our production and provide
only partial price protection against declines in oil and gas prices. These
hedging arrangements will

                                      17


remain in place following the transactions and may expose us to risk of
financial loss in some circumstances, including instances where production is
less than expected or where the other party to any hedging arrangement fails
to perform. In addition, the hedging arrangements may limit the benefit to
Carbon of increases in the prices of oil or gas.

There are numerous risks relating to drilling activities.

   Our success will be materially dependent upon the continued success of our
drilling program. Oil and gas drilling involves numerous risks, including the
risk that no commercially productive oil or gas reservoirs will be
encountered. The cost of drilling, completing and operating wells is often
uncertain, and drilling operations may be curtailed, delayed or canceled as a
result of a variety of factors, including:

  .  unexpected drilling conditions,

  .  pressure or irregularities in formations,

  .  equipment failures or accidents,

  .  adverse weather conditions,

  .  compliance with governmental requirements, and

  .  shortages or delays in the availability of drilling rigs and the
     delivery of equipment.

   Our future drilling activities may not be successful and, if drilling
activities are unsuccessful, such failure will have an adverse effect on our
future results of operations and financial condition. Although we have
identified numerous drilling prospects, we cannot assure you that those
prospects will be drilled or that oil or gas will be produced from them.

Technological changes in the industry could reduce our competitiveness.

   The oil and gas industry experiences rapid and significant technological
advancements and introduction of new products and services using new
technologies. As others use or develop new technologies, we may be placed at a
competitive disadvantage, and competitive pressures may force us to implement
new technologies at substantial costs. In addition, our competitors may have
greater financial, technical and personnel resources that allow them to enjoy
technological advantages and may in the future allow them to implement new
technologies sooner than us. There can be no assurance that we will be able to
respond to such competitive pressures and implement such technologies on a
timely basis or at an acceptable cost. One or more of the technologies we
currently utilize may become obsolete in the future. In such cases, our
business, financial condition and results of operations could be materially
adversely affected. If we are unable to use the most advanced commercially
available technology, our business, financial condition and results of
operations could be materially and adversely affected.

                              THE EXCHANGE OFFER

General

   We are offering to exchange one share of our common stock for each share of
CEC common stock. If all CEC shareholders accept our offer, in the aggregate
we will issue approximately 1,521,400 shares of our common stock. Our common
stock has been approved for listing on the AMEX, upon issuance of the shares
after the exchange offer, under the symbol "      ." CEC's Board of Directors
has approved this exchange offer.

   The exchange offer is open to all holders of CEC common stock. We are
sending this prospectus and related exchange offer documents to persons who
held CEC common stock at the close of business on                , 1999. On
that date, there were            shares of CEC common stock outstanding, which
were held of record by approximately          shareholders. We will also
furnish this prospectus and related exchange offer documents to brokers, banks
and similar persons whose names or the names of whose nominees appear on CEC's
shareholder list or, if applicable, who are listed as participants in a
clearing agency's security position listing for subsequent transmittal to
beneficial owners of CEC common stock.

Background Of The Exchange Offer/Exchange Agreement

   The information in this section regarding the deliberations of CEC's Board
of Directors and the actions of CEC's management and legal and financial
advisors is based on information furnished by CEC.

   As part of a strategy of increasing its natural gas and oil reserves
through acquisitions and exploration and development, CEC has evaluated
property and corporate acquisition opportunities in Alberta, Canada and the
Rocky Mountain region of the United States.

   CEC believes there are attractive opportunities available for acquisitions
and exploration and production in both the United States and Canada as a
result of improving oil and gas prices, lower exploration and production
costs, the divestiture of non-core properties in the industry generally and
consolidation within the oil and gas industry. CEC's position as a small
independent public oil and gas company limits its potential for growth unless
steps are taken to increase its size and the value of its oil and gas
reserves.

   In July, 1998, Patrick R. McDonald purchased shares of CEC and became
President, Chief Executive Officer and a member of the Board of Directors. Mr.
McDonald hired a team of professional oil and gas managers and began to
develop CEC's Canadian natural gas properties through the acquisition of
additional interests in the Carbon Gas Field in Alberta, Canada. Since July,
1998, CEC has completed five transactions resulting in an increase in CEC's
proved natural gas and oil reserves in Canada.

   CEC's growth strategy included the acquisition and exploration and
development of oil and gas properties in the United States. During 1998 and
1999, CEC management reviewed and evaluated oil and gas acquisition
opportunities in the Rocky Mountain region of the United States. In early May,
1999, CEC learned that BPC planned to sell the stock of its Denver based 100%
owned subsidiary, BFC. On May 10, 1999, CEC executed a confidentiality letter
and received information relating to the oil and gas wells and reserves owned
by BFC. In accordance with the schedule established by BPC, CEC submitted an
initial non-binding expression of interest in purchasing BFC for a total of
$24,500,000 in cash, plus net debt remaining at BFC equal to approximately
$6,500,000. BPC advised CEC that several other parties had also submitted
offers and that BFC would conduct a sale process designed to result in a
transaction with the most preferred buyer. Contemporaneously, the management
of Yorktown was also apprised of CEC's interest in BFC and was asked to
consider providing the financing for the transaction. The Board of CEC was
advised of and reviewed each of these actions.

   On May 21, 1999, CEC was notified that it should conduct additional due
diligence and on May 27 and 28, 1999, CEC met with management of BFC and
reviewed the business and operations of BFC.


                                      19


   On June 9, 1999, based on the results of due diligence, CEC advised BPC
that, if BPC would negotiate on an exclusive basis, CEC would be willing to
discuss a transaction to acquire BFC in the range of $28,500,000 in cash plus
$6,500,000 in net debt remaining with BFC. Based on discussions with Yorktown,
the offer was not subject to a financing contingency. BPC informed CEC that it
would not accept CEC's offer to negotiate exclusively and requested that CEC
continue to participate in the sale process.

   On June 18, 1999, BPC advised CEC that a final offer for BFC would be due
June 28, 1999. On June 28, 1999, CEC submitted an offer to BPC in the amount
of $20,000,000 in cash for the assets of BFC plus the assumption of $6,500,000
in net debt outstanding at March 31, 1999.

   CEC was informed in early July that BPC had elected to negotiate a stock
purchase agreement with another party. In mid July, CEC inquired as to whether
BPC's position had changed and whether BPC would be willing to discuss further
CEC's June 28, 1999 offer. BPC indicated that it would consider that offer if
CEC would submit for review comments on the form of the stock purchase
agreement prepared by BPC and increase the price it was willing to pay for
BFC.

   On July 22, 1999, the Board of Directors of CEC met at a regularly
scheduled Board meeting. Among items discussed was the status of the BFC
transaction, the status of the financing for the transaction to be provided by
Yorktown and the reasons for CEC's interest in an acquisition of BFC. CEC's
Board directed Mr. McDonald to continue discussions with BPC and Yorktown and
to report back to the Board as to the results of those discussions.

   On July 27, 1999, CEC submitted comments on the form of the stock purchase
agreement to BPC for review. During the period July 28 to July 30, BPC and CEC
conducted additional negotiations relating to the terms of the proposed stock
purchase agreement and the price to be paid for the stock of BFC. BPC advised
that CEC's June 28 offer would not be sufficient to ensure the purchase of
BFC. Based on discussions with the Board of CEC and Yorktown, on July 30, 1999
CEC agreed to increase its offer for BFC to $24,000,000 in cash for the stock
of BFC plus $6,500,000 of net debt remaining with BFC. On July 31, 1999, CEC
and BPC executed a Letter of Intent proposing to accept CEC's offer to
purchase BFC and agreeing to negotiate a definitive stock purchase agreement.

   On August 11, 1999, CEC conducted a special Board of Directors meeting
during which the status of the BFC transaction and the Yorktown financing was
discussed and the purchase of BFC was approved. The Board of CEC reviewed the
position of CEC within the oil and gas industry, its growth prospects in the
United States and Canada, the present valuation of CEC as a small independent
oil and gas company and its access to future capital to provide growth. The
Board discussed the terms of the BFC stock purchase agreement, including the
price, the representation and warranties of BPC, the requirement for
additional due diligence and obligations of CEC. The Board also considered the
financing as proposed generally by Yorktown, the valuation of CEC and other
factors described in "--CEC's Reasons For Recommending The Exchange Offer."

   As indicated above, the Board reviewed the valuation of CEC and BFC by
Yorktown based on what would be the economic equivalent of paying $5.50 per
share of CEC. The Board believed that this price was fair and consistent with
valuation of independent oil and gas companies of similar size based on the
experience of the Board, the current market price for the stock of CEC and by
various industry measures of value including discounted cash flow and multiple
cash flow methods.

   The structure of the proposed transaction with BFC and Yorktown was
reviewed and approved by the Board of CEC. Yorktown required that its
investment be in a United States corporation. Because CEC would face
unfavorable tax consequences if it became a U.S. corporation, it was decided
to form Carbon as a Colorado corporation. With commitment for a financing and
an understanding that an exchange offer by the new United States corporation
controlled by Yorktown would be made for shares of CEC common stock; on August
11, 1999, CEC and BPC signed the BFC stock purchase agreement. CEC issued a
press release on August 12, 1999, announcing execution of that agreement,
describing the terms of the financing to be provided by Yorktown and
describing the overall structures of the transactions.

                                      20


   On October 14, 1999, Carbon, CEC and Yorktown signed the exchange and
financing agreement ("Exchange Agreement"). Under the Exchange Agreement,
Yorktown agreed to acquire 4,500,000 shares of Carbon common stock at a
purchase price of $24,750,000 in cash, which is $5.50 per share. Carbon agreed
to use the proceeds for the purchase of BFC shares under the BFC stock
purchase agreement and to add any remaining proceeds to the working capital of
Carbon. CEC agreed to assign to Carbon its rights and obligations under the
BFC stock purchase agreement for BFC stock, and Carbon agreed to assume the
obligations and terms of CEC under the BFC stock purchase agreement. Also,
Carbon, CEC and Yorktown agreed that Carbon would make an offer to all holders
of shares of CEC to exchange one share of common stock of Carbon for each
outstanding share of CEC, subject only to a few conditions. CEC and its Board
of Directors approved this exchange offer. The Exchange Agreement also
provided for the adoption of a stock option and restricted stock plan of
Carbon, employment agreements with Mr. McDonald and Kevin D. Struzeski,
Carbon's Treasurer and Chief Financial Officer.

   The Exchange Agreement further contained provisions regarding the
composition of Board of Directors of Carbon. These provisions are described
under "--Description of Exchange Agreement" below.

   On October   , 1999, CEC assigned the BFC stock purchase agreement to
Carbon. On October 29, 1999, Carbon completed the purchase of BFC for
$            in cash.

CEC's Reasons For Recommending The Exchange Offer

   CEC's Board of Directors believe that the terms of the exchange offer are
fair to and in the best interests of CEC and its shareholders. In reaching its
conclusion to approve the BFC stock purchase agreement, the exchange and
financing agreement and the exchange offer, CEC's Board consulted with
management, as well as its legal advisors, and considered the following
factors:

  .  The acquisition of BFC and the exchange offer would result in Carbon
     being led by a highly regarded management team with a strong track
     record in the oil and gas industry.

  .  The structure of the transaction with CEC's current shareholders having
     the opportunity to participate in the future value of both BFC and CEC
     as part of Carbon by accepting the exchange offer.

  .  Reasons for the acquisition of BFC, including potential growth, the
     nature of BFC's properties and cost savings that may be realized in the
     operation of BFC by Carbon.

  .  The terms of the BFC stock purchase agreement, including the parties'
     representations, warranties and covenants and the conditions to their
     respective obligations.

  .  United States and Canadian tax consequences of the transaction.

  .  The requirement of Yorktown that its equity financing be made through a

   The foregoing discussion of the information and factors considered by CEC's
Board of Directors is not intended to be exhaustive but is believed to include
all material factors considered by CEC's Board. In reaching its determination
to approve the stock purchase agreement, the exchange and financing agreement
and the exchange offer, the CEC Board concluded that the potential benefits of
the purchase of BFC stock and exchange offer outweighed the potential risks,
but did not, in view of the wide variety of information and factors
considered, assign any relative or specific weights to the foregoing factors,
and individual directors may have given differing weights to different
factors. Although directors, executive officers and other personnel of CEC
have interests in the exchange offer, as described under "Interests of Certain
Persons in the Exchange Offer," CEC's Board did not consider the potential
benefits to be received by these individuals as a factor in reaching its
decision to approve the BFC stock purchase agreement, the Exchange Agreement
and the exchange offer.

Our Reasons For The Exchange Offer

   As part of the Exchange Agreement in which Carbon obtained the right to
purchase BFC stock from CEC, Carbon agreed to make the exchange offer. In
approving the Exchange Agreement and the making of the exchange offer,
Carbon's Board of Directors concluded that the purchase of the BFC stock and
the acquisition of control of CEC pursuant to the exchange offer would result
in Carbon being a more significant independent oil and gas company and having
a management team with a strong track record in the oil and gas industry.

Intentions Of The Directors And Officers Of CEC

   The directors and executive officers of CEC who own, in the aggregate,
580,346 shares of outstanding CEC common stock, representing approximately
38.1% of CEC's outstanding shares, have stated they intend to accept our
offer.

Interests Of Certain Persons In The Exchange Offer

   In considering whether to accept the exchange offer, you should be aware of
the interests various executive officers and a director of CEC may have in the
exchange offer. In this regard, you should consider, among other things, the
employment agreements, stock options, restricted stock grants and bonuses
described below.

   On           , 1999, Patrick R. McDonald and Carbon entered into a three-
year employment agreement, which provides for Mr. McDonald to be the President
and Chief Executive Officer of Carbon at a base salary of not less than
US$200,000 per year, to be adjusted on each July 1 for cost of living
increases in the U.S. consumer price index. Carbon is to provide Mr. McDonald
benefits that he currently receives as an executive of CEC, and is to maintain
for his benefit a life insurance policy in the amount of $1 million and a
disability insurance policy with terms mutually agreeable to us and Mr.
McDonald. According to the employment agreement, Carbon is also to nominate
and endorse Mr. McDonald as a director on Carbon's Board of Directors so long
as he is an officer of Carbon.

   Either Carbon or Mr. McDonald may terminate the agreement if there is a
change in control of Carbon. A change in control includes (1) the acquisition
by a third party or a group of 50% or more of the combined voting power for
election of Carbon's directors (excluding those owned by Yorktown or entities
controlled by
Yorktown), or (2) the acquisition of Carbon by merger after which Carbon
shareholders do not own more than 2/3
of the outstanding voting securities of the surviving corporation in
substantially the same proportion as they owned
Carbon prior to the merger, or any sale or exchange or other disposition of
all or substantially all of our assets, (3) or the sale or other disposition
of more than 50% in fair market value of our assets other than in the ordinary
course of business, whether in a single transaction or related transactions,
or (4) there is a change in more than a majority of our Board of Directors as
a result of a proxy contest waged by a third party unaffiliated with the
officer who is the party to the employment agreement and not endorsed by that
officer. In the event of a change in control not supported by a majority of
our then-existing Board of Directors, Mr. McDonald is to be paid 400% of his
compensation upon termination of the employment agreement. In the event of a
change in control supported by our then-existing Board of Directors, Mr.
McDonald is to be paid 300% of his compensation upon

                                      22


termination of the employment agreement by us or 200% of his compensation upon
termination of his employment by him. For this purpose, the term compensation
means the average of Mr. McDonald's annual base salary and incentive
compensation for the three years prior to the termination date (or such lesser
period as he has been employed), taking his base salary and incentive
compensation into account at their full annualized rates for any partial year
or years. In addition, upon a change in control, any restrictions on
outstanding incentive awards (including restricted stock and performance
shares) granted to Mr. McDonald will lapse and such incentive awards will
become 100% vested. Further, in the event of a change in control, any stock
options and stock appreciation rights held by Mr. McDonald will become
immediately exercisable and 100% vested.

   If Mr. McDonald's employment is terminated by us for any reason other than
"cause" (as defined below) or upon the death or disability of Mr. McDonald or
if Mr. McDonald terminates his employment because of a material breach of the
employment agreement by Carbon or because of a change in the position of Mr.
McDonald with Carbon, then Mr. McDonald is to be paid a lump sum payment equal
to 300% of his compensation as defined above. Also, in that event, all his
options and restricted stock become 100% vested. "Cause" means (1) repeated
refusal to obey written directions of our Board or a superior officer, (2)
repeated acts of substance abuse which are materially injurious to Carbon, (3)
fraud or dishonesty which is materially injurious to Carbon, (4) breach of any
material obligation of nondisclosure or confidentiality owed to Carbon, (5)
commission of a criminal offense involving our money or property, or (6)
commission of a criminal offense that constitutes a felony.

   If a payment to Mr. McDonald is subject to an excise tax under the Internal
Revenue Code, we will pay to Mr. McDonald an additional amount to cover the
excise tax on an after-tax basis.

   As required by his employment agreement, Carbon has granted under its 1999
stock option plan to Mr. McDonald an option to acquire 70,000 shares of our
common stock at $5.50 per share. Carbon has also granted to Mr. McDonald
30,000 shares of restricted common stock under its 1999 restricted stock plan.
The shares subject to the option and the restricted stock vest over three
years, with one-third of the stock vested on October 14, 2000 (which is one
year from the date of grant) and one-third of the stock vested on each of the
second and third anniversaries of the date of grant.

   On              , 1999, we entered into a two-year employment agreement
with Mr. Struzeski, which provides for Mr. Struzeski to be the Chief Financial
Officer of Carbon at a base salary of US$100,000 per year, together with all
benefits offered by us to our employees generally. The employment agreement
with Mr. Struzeski provides that either Carbon or Mr. Struzeski may terminate
the contract if there is a change in control of Carbon. Change in control is
defined in the same manner under this contract as our employment agreement
with Mr. McDonald. In the event of a change in control not supported by a
majority of our then-existing Board of Directors, Mr. Struzeski is to be paid
300% of his compensation upon termination of the employment agreement. In the
event of a change in control supported by our then-existing Board of
Directors, Mr. Struzeski is to be paid 200% of his compensation upon
termination of his employment agreement by us or 100% of his compensation upon
termination of his employment by him. For this purpose, compensation means the
average of Mr. Struzeski's annual base salary and incentive compensation for
the two years prior to the date of termination, (or, if he has been employed
for less than two years, such lesser number of calendar years during any part
of which he has been employed, with his base salary and incentive compensation
taken into account at their full annualized rates for any partial year or
years), prorated to be a monthly amount and multiplied by the remaining months
of the term of his agreement (but not less than 12 months). Also, in the event
of a change in control, the restrictions on any outstanding incentive awards
(including restricted stock and performance shares) granted to Mr. Struzeski
will lapse and such awards and all stock options and stock appreciation rights
granted to him will become immediately exercisable and will become 100%
vested.

   If Mr. Struzeski's employment is terminated by us for any reason other than
"cause" (defined the same as in Mr. McDonald's employment agreement) or upon
the death or disability of Mr. Struzeski or if Mr. Struzeski terminates his
employment because of a change in the position of Mr. Struzeski with Carbon,
Carbon is pay Mr. Struzeski an amount equal to his compensation (pro rated on
a monthly basis) multiplied by the remaining months of his employment
agreement. Also, in that event, all his options and restricted stock become
100% vested.

                                      23


   Carbon has also granted to Mr. Struzeski an option to acquire 25,000 shares
of common stock at $5.50 per share under its 1999 stock option plan and 10,000
shares of restricted common stock under its 1999 restricted stock plan. The
shares subject to the options and the restricted stock vest over three years,
with one-third of the stock vested on October 14, 2000 (which is one year from
the date of grant) and one-third of the stock vested on each of the second and
third anniversaries of the date of grant.

   In recognition of Mr. McDonald's role in the purchase of BFC by Carbon and
the exchange offer, the Board of Directors of CEC has determined that CEC will
pay to Mr. McDonald a bonus of $200,000 Canadian (approximately $134,000 U.S.)
when 50% or more of CEC shares are exchanged for Carbon shares. Similarly,
other officers of CEC, including Mr. Struzeski, are to receive bonuses from
CEC at the same time. Mr. Struzeski's bonus will be $        Canadian
(approximately $        U.S.).

Description of Exchange Agreement

   Under the Exchange Agreement, Yorktown agreed to acquire 4,500,000 shares
of Carbon common stock at a purchase price of $24,750,000 in cash, or $5.50
per share. Carbon agreed to use these proceeds for the purchase of BFC shares
under the BFC stock purchase agreement with any remaining proceeds to be added
to its working capital. CEC agreed to assign to Carbon its rights and
obligations under the BFC stock purchase agreement and Carbon agreed to assume
those rights and obligations. Carbon, CEC and Yorktown agreed that Carbon
would make the exchange offer to all CEC shareholders. CEC agreed that its
Board would recommend acceptance of the exchange offer. The Exchange Agreement
also provided for the adoption of our 1999 stock option plan and our 1999
restricted stock plan, and employment agreements with Mr. McDonald and Mr.
Struzeski.

   Carbon, CEC and Yorktown agreed that the Board of Directors of Carbon would
consist of five directors. Carbon, CEC and Yorktown agreed that the five
directors initially would be David H. Kennedy, Lambros J. Lambros, Bryan H.
Lawrence, Peter A. Leidel and Patrick R. McDonald. Upon completion of the
exchange offer, if Harry A. Trueblood accepts the exchange offer for all CEC
common stock owned beneficially by him, the number of Carbon directors will be
six and Mr. Trueblood will be the sixth director. As long as Yorktown
beneficially owns shares with 50% or more of the outstanding votes in the
election of directors of Carbon, Yorktown has the right to designate for
nomination two directors. If Yorktown owns beneficially shares with 25% or
more but less than 50% of the outstanding votes in the election of directors
of Carbon, then Yorktown has the right to designate for nomination one
director. Yorktown has no right to designate directors for nomination under
the Exchange Agreement if Yorktown owns beneficially shares with less than 25%
of the outstanding votes in the election of directors of Carbon. So long as
Mr. McDonald is an officer of Carbon, he is to be designated for nomination as
a director of Carbon.

   Under the Exchange Agreement, a nominating committee of our Board was
established. The nominating committee consists of one Yorktown designated
director, Mr. McDonald so long as he is a director of Carbon, and two
independent directors. The nominating committee is responsible for determining
nominees for the positions of directors of Carbon or persons to be elected by
the Board of Directors or shareholders of Carbon to fill any vacancy in the
Board of Directors. The nominating committee is required to nominate for
director each Yorktown director which Yorktown has the right to designate and
has designated. The nominating committee is required to nominate Mr. McDonald
if he is entitled to be nominated. The nominating committee will then nominate
the remaining directors; at least two of the persons nominated will be
independent directors. If the size of the Board is changed and there are not
sufficient positions for the election of two independent directors after
taking into account the directors designated by Yorktown and Mr. McDonald,
then the nominating committee is not required to nominate two independent
directors. If there is a vacancy in the position relating to a Yorktown
director, the remaining Yorktown director has the right to designate any
replacement to fill the vacancy. The nominating committee has the right to
designate any replacement to fill any other vacancy. The Exchange Agreement
requires that any change in the size or composition of the Board of Directors
or the nominating committee be approved by a supermajority vote of the Board
consisting of a majority of the entire Board which includes a majority of all
Yorktown directors and at least one independent director. Yorktown and Mr.
McDonald agreed to take such actions as shareholders of Carbon as necessary to
effectuate the election of directors

                                      24


nominated pursuant to the foregoing provisions. The provisions relating to
election of directors cease to be effective on October 29, 2009 or, if
earlier, when Yorktown owns beneficially shares with less than 25% of the
outstanding votes in the election of directors and Mr. McDonald is no longer
an officer of Carbon.

   We agreed to grant under our stock option plan substitute options for each
option outstanding under the CEC stock option plan. Any option granted by us
in substitution for an option granted under the CEC stock option plan will
provide that it is being granted in full satisfaction of, and in substitution
for, any and all options for CEC stock previously granted under the CEC stock
option plan. The material terms and conditions will be the same as those
relating to the specific options granted under the terms of CEC stock option
plan.

   You have until 5:00 p.m., Denver time, on               , 1999 to accept
our offer, unless extended. At that time, our offer will expire. If we extend
the expiration date, we will publicly announce the extension as soon as
practicable after we make the extension, and in any event no later than 9:00
a.m. Denver time on the next business day after the previously scheduled
expiration date. Without limiting the manner in which we may choose to make a

the public announcement other than by making a release to the Dow Jones News
Services.

Exchange Of CEC Stock For Carbon Common Stock

   If you deliver a properly completed and executed letter of transmittal,
which you received along with this prospectus, and stock certificates
representing your shares of CEC common stock prior to the expiration date to
the exchange agent at its address, then you will have accepted the exchange
offer as to the number of shares reflected on the stock certificates
delivered.

   Except as provided below, all signatures on a letter of transmittal must be
guaranteed by a member firm of a registered national securities exchange or of
the National Association of Securities Dealers, Inc., a commercial bank or
trust company having an office or correspondent in the United States or an
"eligible guarantor institution" within the meaning of Rule 17Ad-15 under the
Securities Exchange Act of 1934, which is a member of one of the recognized
signature guarantee programs identified in the letter of transmittal (each
such institution is referred to in this prospectus as an "eligible
institution"). Signatures on a letter of transmittal need not be guaranteed
if:

  .  the letter of transmittal is signed by the registered holder of the
     shares of the CEC common stock tendered therewith and the registered
     holder has not completed the box entitled "Special Exchange
     Instructions" on the letter of transmittal, or

  .  the shares of the CEC common stock tendered therewith are for the
     account of an eligible institution.

   You must choose how to deliver the letter of transmittal, stock
certificates and other necessary documents to the exchange agent, and you bear
the risk of how you make this delivery. We recommend that you use an overnight
or hand delivery service rather than a mail service. In all cases, you should
allow sufficient time to assure timely delivery. You should send the letter of
transmittal, stock certificates and other necessary documents to the exchange
agent at the address provided in this prospectus and the letter of
transmittal.

   If you want us to issue the Carbon common stock in a name other than the
name in which your CEC stock certificates are registered, you must properly
endorse or otherwise place in proper form for transfer your stock certificates
so surrendered. The person requesting this exchange must pay to Carbon or the
exchange agent any applicable transfer or other taxes required due to the
issuance of this certificate. If your CEC certificates are registered in the
name of your broker, dealer, commercial bank, trust company, or other nominee
and you wish to tender your shares, you should contact the registered holder
promptly and instruct the registered holder to tender on your behalf. If your
stock certificates are registered in the name of the registered holder and you
wish

                                      25


to tender on your own behalf, you must, before completing and executing the
letter of transmittal and delivering the letter of transmittal, stock
certificates, and other necessary documents, either arrange to register your
shares in your name or obtain a properly completed stock power from the
registered holder.

   If the letter of transmittal is signed by a person other than the
registered holder of any of the CEC common stock listed therein, the stock
certificates reflecting ownership of this CEC common stock must be endorsed or
accompanied by appropriate stock powers that authorize this person to tender
the CEC common stock on behalf of the registered holder, in either case signed
as the name of the registered holder or holders appears on these stock
certificates.

   If the letter of transmittal, any stock certificates representing the CEC
common stock tendered, or any stock powers are signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of a corporation or
others acting in a fiduciary or representative capacity, these persons should
so indicate when signing and, unless waived by us, submit with the letter of
transmittal evidence satisfactory to us of their authority to so act.

   After the expiration date the exchange agent will send us written notice of
the amount of the outstanding CEC common stock validly tendered in the
exchange offer. Promptly after we receive this notice, if all the conditions
to the offer are satisfied or waived, then we will exchange each validly
tendered share of CEC common stock for shares of Carbon common stock at the
exchange rate described above. We then will deliver by registered mail Carbon
common stock representing the CEC common stock that has been tendered.

   All questions as to the validity, form, eligibility, acceptance and
withdrawal of the tendered shares of the CEC common stock will be determined
by us in our sole discretion, and our determination will be final and binding.
We reserve the absolute right to reject any and all shares of the CEC common
stock not properly tendered or any shares of the CEC common stock our
acceptance of which would, in the opinion of our counsel, be unlawful. We
reserve the absolute right to waive any irregularities or conditions of
tenders as to particular shares of the CEC common stock. Unless waived by us,
any defects or irregularities in connection with tenders of shares of the CEC
common stock must be cured within the time we determine. Neither we, the
exchange agent nor any other person shall be under any duty to give
notification of defects or irregularities with respect to tenders of shares of
the CEC common stock or withdrawal of shares nor shall any of them incur any
liability for failure to give any notification. Tenders of shares of the CEC
common stock will not be deemed to have been made until such defects or
irregularities have been cured or waived. As soon as practicable following the
expiration date, the exchange agent will return without cost any stock
certificates representing the CEC common stock that were not properly tendered
and as to which defects or irregularities have not been cured or waived to the
tendering holder of these stock certificates, unless otherwise provided in the
letter of transmittal.

   If any of the stock certificates representing your CEC common stock have
been mutilated, lost, stolen or destroyed, you should contact the exchange
agent at the address below for further instruction.

Guaranteed Delivery Procedures

   CEC's shareholders who wish to tender their shares of the CEC common stock
and whose stock certificates representing the CEC common stock are not
immediately available or who cannot deliver the letter of transmittal, their
stock certificates, or any other required documents to the exchange agent
prior to the expiration date, may effect a tender if:

  .  the tender is made through an eligible institution, and

  .  prior to the expiration date, the exchange agent receives from this
     eligible institution a properly completed and duly executed notice of
     guaranteed delivery, which you received along with this prospectus, that
     sets forth the name and address of the holder of the CEC common stock,
     the certificate number or numbers of the CEC common stock, and the
     number of shares of the CEC common stock tendered thereby, and

  .  states that the tender is being made thereby, and

  .  guarantees that, within three business days after the expiration date,
     the letter of transmittal, the stock certificates representing the CEC
     common stock to be tendered in proper form for transfer, and any other
     necessary documents will be deposited by the eligible institution with
     the exchange agent, and

  .  a properly completed and executed letter of transmittal, together with
     the stock certificates representing all the tendered CEC common stock in
     proper form for transfer, and all other necessary documents are received
     by the exchange agent within three business days after the expiration
     date.

Conditions To The Exchange

   We will be under no obligation to accept shares of CEC common stock
tendered if prior to the expiration date any court or other governmental
entity shall have issued an order restraining, enjoining or otherwise
prohibiting consummation of the exchange offer.

Termination Of The Exchange Offer

   Our exchange offer, as well as the Exchange Agreement may be terminated at
any time prior to the expiration date if:

  .  the parties to the Exchange Agreement agree to the termination, or

  .  by any party if any court or governmental authority of competent
     jurisdiction shall have issued a final order restraining, enjoining or
     otherwise prohibiting consummation of the transactions contemplated by
     the Exchange Agreement.

If the exchange offer is terminated without our acceptance of any shares of
the CEC common stock tendered, we will promptly return all shares tendered to
the appropriate CEC shareholders.

Withdrawal Rights

   You may withdraw tenders of your shares of the CEC common stock at any time
before the exchange offer expires. If you change your mind again, you may
retender your shares of the CEC common stock by following the exchange offer
procedures again prior to the expiration of the exchange offer.

   For a withdrawal to be effective, a written notice of withdrawal must be
received by the exchange agent at one of its addresses set forth in the
section of this prospectus titled "--The Exchange Agent." The notice of
withdrawal must:

  .  specify the name of the person having tendered the shares of the CEC
     common stock to be withdrawn,

  .  identify the number of shares of the CEC common stock to be withdrawn,
     and

  .  specify the name in which physical share certificates representing the
     CEC common stock are registered, if different from that of the
     withdrawing holder.

                                      27


   If certificates for the CEC common stock have been delivered or otherwise
identified to the exchange agent, then, before the release of such
certificates, the withdrawing holder must also submit the serial numbers of
the particular certificates to be withdrawn and a signed notice of withdrawal
with signatures guaranteed by an eligible institution unless such holder is an
eligible institution.

   Any shares of the CEC common stock withdrawn will be deemed not to have
been validly tendered for exchange for purposes of our offer. Any shares which
have been tendered for exchange but which are not exchanged for any reason
will be promptly returned to the holder who tendered the shares. Properly
withdrawn shares may be retendered by following one of the procedures
described in this prospectus and the letter of transmittal.

   Except as otherwise provided above, any tender of shares of the CEC common
stock made under the exchange offer is irrevocable.

Fees And Expenses

   We will bear the expenses of soliciting tenders. The principal solicitation
is being made by mail; however, additional solicitation may be made by
telegraph, telephone or in person by our officers and regular employees and
the officers and regular employees of our affiliates.

   We have not retained any dealer-manager in connection with the exchange
offer and will not make any payments to brokers, dealers or others soliciting
acceptances of the exchange offer. We, however, will pay the exchange agent
reasonable out-of-pocket expenses in connection therewith.

   We will pay the cash expenses to be incurred in connection with the
exchange offer, which are estimated in the aggregate to be approximately
          . Such expenses include registration fees, fees and expenses of the
exchange agent for our offer and, accounting and legal fees and printing
costs, among others.

   We will pay all transfer taxes, if any, applicable to the exchange of
Carbon common stock for the CEC common stock in the exchange offer. If,
however, a transfer tax is imposed for any reason other than the exchange of
Carbon common stock for CEC common stock in the exchange offer, then the
amount of any transfer taxes will be payable by the tendering shareholder. If
satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the letter of transmittal, the amount of such transfer taxes
will be billed directly to the CEC stockholder.

Regulatory Matters

   We believe that the exchange offer may be made without notification being
given or information being furnished to the Federal Trade Commission or the
Antitrust Division of the Department of Justice under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, and that no waiting period
requirements under the Hart-Scott-Rodino Act are applicable to our offer.

Accounting Treatment

   For accounting purposes, neither Carbon nor CEC will recognize a gain or
loss as a result of the exchange offer. The exchange offer of Carbon shares
for CEC shares and the purchase of BFC by Carbon will be accounted for by
Carbon as a purchase in accordance with generally accepted accounting
principles. The purchase method requires that the cost of the acquisition
(i.e., cash, stock and net liabilities assumed), plus deferred taxes related
thereto, be allocated among the assets and liabilities acquired based upon
their fair value. The purchase method, when applied to oil and gas exploration
and production companies, prohibits the allocation of the purchase price to
goodwill. Any resulting excess in the book value of the oil and gas properties
will be written off in accordance with the ceiling test followed in the full
cost method of accounting. The assets and liabilities and results of
operations of CEC will be consolidated into the assets and liabilities and
results of operations of Carbon after consummation of the exchange offer.

                                      28


Possible Effects of the Exchange Offer

   The exchange of shares of CEC common stock in the exchange offer will
reduce the number of holders of CEC common stock and the number of shares of
CEC common stock that might otherwise trade publicly. Depending on the number
of shares of CEC common stock exchanged, the liquidity and market value of the
remaining shares of CEC common stock could be adversely affected. CEC's common
stock is listed on the AMEX. Depending on the number of shares of CEC common
stock exchanged pursuant to the exchange offer, the CEC common stock may no
longer meet the requirements of the AMEX for continued listing. Currently,
AMEX will normally consider suspending trading in shares of an issuer when any
one or more of the following conditions exist:

  .  the number of shares publicly held exclusive of holdings of officers,
     directors and controlling shareholders such as Yorktown (or other family
     or concentrated holdings) is less than 200,000; or

   .  the total number of public shareholders is less than 300; or

   .  the aggregate market value of shares publicly held is less than
$1,000,000

Upon completion of the exchange offer, it is likely that the CEC common stock
will be delisted from the AMEX.

   If the shares of CEC common stock are delisted from the AMEX, the market
for such shares could be adversely affected. It is possible that such shares
might not be traded on other public securities exchanges. The extent of any
public market for the shares of CEC common stock would, however, depend upon
the number of holders and/or the aggregate market value of such shares
remaining at that time, the interest in maintaining a market in such shares on
the part of securities firms and the possible termination of registration of
CEC common stock under the Exchange Act. The trading in CEC common stock prior
to the exchange offer was thin and inactive; it can be expected that there
will be no public market for CEC common stock after the exchange offer.

   CEC's common stock is currently registered under the Exchange Act. Such
registration may be terminated by CEC upon application to the SEC if the
outstanding shares of CEC common stock are not listed upon a national
securities exchange and if there are fewer than 300 holders of record of such
shares. Termination of registration of the CEC common stock under the Exchange
Act would reduce the information required to be furnished by CEC to its
shareholders and to the SEC and would make certain provisions of the Exchange
Act, such as the short-swing recovery provisions of Section 16(b) and the
requirement of furnishing a proxy statement pursuant to Section 14(a), no
longer applicable to such shares.

Second Step Merger

   After the exchange, we may merge CEC with a wholly-owned Canadian
subsidiary of Carbon. In such a merger, shareholders of CEC may receive cash,
shares of our stock, other securities or a combination of some or all of the
foregoing. Whether we decide to proceed with a merger depends upon a number of
factors which cannot be ascertained at the present time. These factors include
the number of shares which are tendered in our offer, the relative
attractiveness of completing the merger compared to investing our resources in
other investments, the availability of financing to fund the cash portion of
the consideration required to effect the merger, and the U.S. and Canadian tax
consequences of the merger. The more CEC shares tendered in the exchange
offer, the more likely it is that we will effect the merger as less cash will
be required to pay for the remaining shares. The merger will have no effect on
CEC shareholders who accept our current exchange offer. It will affect,
however, CEC shareholders who do not accept our offer. If we proceed with a
merger, we may give those shareholders cash for their shares of CEC common
stock.

   We do not intend to do a second step merger if it would result in adverse
United States income tax consequences to CEC shareholders who accepted our
exchange offer. We will not engage in a second step merger without informing,
and receiving approval from, our tax counsel.

   If CEC common stock is listed on the AMEX on the record date for
determining shareholders entitled to vote on the merger, no dissenters' rights
will be available to CEC's shareholders in connection with the merger. In
contrast, if CEC's common stock is not listed on the AMEX on such record date,
CEC's shareholders will be entitled to dissenters' rights in connection with
the merger.

                 UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

Scope and Limitation Advice.

   In the opinion of Holland & Hart, LLP, tax counsel to CEC, the following
are the material United States federal income tax considerations arising from
and relating to the exchange of CEC common stock for Carbon common stock that
are generally applicable to you if you are a "U.S. Shareholder" and, in some
cases, if you are a "non-U.S. Shareholder." You are a U.S. Shareholder if you
are a United States citizen or resident, domestic corporation, domestic
partnership, estate subject to United States federal income tax on its income
regardless of source, or trust, but only if a court within the United States
is able to exercise primary supervision over the administration of the trust
and one or more United States fiduciaries have the authority to control all
the substantial decisions of the trust. You are a non-U.S. Shareholder if you
are not a U.S. Shareholder.

   This discussion does not address all aspects of U.S. federal income
taxation that may be relevant to you, particularly if you are subject to
special treatment under United States federal income tax laws. For example,
this discussion does not address the potential application of the alternative
minimum tax; or the tax consequences to certain types of investors subject to
special treatment under U.S. federal income tax laws, such as: banks, life
insurance companies, tax-exempt organizations, broker-dealers or holders of
Carbon common or CEC common stock who received such stock as compensation.

   In addition, this discussion does not address any aspect of state, local or
foreign tax laws.

   This discussion is based on the Internal Revenue Code of 1986, as amended
(the "Code"), existing and proposed regulations, IRS rulings and
pronouncements, reports of congressional committees, judicial decisions and
current administrative rulings and practice, all as of October 20, 1999, which
are subject to change. Any such change could be retroactive and change the tax
consequences discussed below. No advance ruling from the Internal Revenue
Service with respect to these matters has been requested.

   The following does not address all aspects of federal income taxation that
may be relevant to you in light of your individual circumstances and tax
situation. You are urged and expected to consult your own tax advisors as to
the particular tax consequences to you.

Taxation of U.S. Shareholders.

   The following discussion applies to you if you are a U.S. Shareholder and:

  .  you hold CEC common shares and/or will hold Carbon common stock as
     "capital assets," defined below, within the meaning of Section 1221 of
     the Code;

  .  your ownership, receipt or disposition of CEC common shares and/or
     Carbon common stock is not attributable to a permanent establishment in
     a country other than the United States for purposes of an income tax
     treaty to which the United States is a party; and

  .  you are not a resident of a country other than the United States for
     purposes of an income tax treaty to which the United States is a party.

   If you are a U.S. Shareholder and do not meet all of the foregoing
criteria, you should consult your tax advisors regarding your particular U.S.
federal income tax consequences.

Basic Treatment of Exchange Transaction for U.S. Shareholders.

   For U.S. federal income tax purposes, the tax-free nature of the exchange
of CEC common shares for Carbon common stock can be established in two
separate ways.

   First, the exchange may, if certain requirements are satisfied, qualify as
a so-called "B Reorganization" under relevant U.S. federal income tax law. A
transaction generally constitutes a B Reorganization if, among other things,
an acquiring corporation (Carbon) has "control" of a target corporation (CEC)
immediately

                                      30


following an exchange of the target corporation's shares for the acquiring
corporation's shares, but only if stock representing "control" of the target
corporation (CEC) was acquired solely for voting stock. For this purpose,
"control" means at least 80% of the total combined voting power of all classes
of stock entitled to vote and at least 80% of the total number of shares of
all other classes of stock of the corporation. Assuming that Carbon acquires
at least 80% of the outstanding stock of CEC solely in exchange for the stock
of Carbon, and that the representations made by Carbon and CEC to tax counsel
are accurate, tax counsel is of the opinion that the exchange should qualify
for tax-free treatment as a B Reorganization.

   Even if the exchange does not satisfy the requirements for a tax-free B
Reorganization, there nevertheless may be a second means of characterizing the
exchange as tax-free. Specifically, if certain requirements are satisfied, it
is likely that the exchange may qualify as a tax-free transaction under
Section 351 of the Code. Under Section 351 of the Code, persons transferring
property to a corporation in exchange for stock of the corporation generally
do not recognize gain or loss on the transfer of their property to the
corporation. However, this favorable treatment applies only if, among other
things, immediately following the exchange, the persons transferring property
to the corporation hold at least 80% of the total combined voting power of all
classes of stock entitled to vote and at least 80% of the total number of
shares of all other classes of stock of the corporation. In addition, in order
for multiple transferors to be taken into account in computing this 80%
control test, the transferors must transfer property to the corporation as
part of the same plan or arrangement.

   Although the matter is not free from doubt, tax counsel believes that
Yorktown's contribution of cash to Carbon and CEC shareholders' subsequent
exchange of CEC common stock for Carbon common stock likely constitute
transfers pursuant to the same plan or arrangement for purposes of Section 351
of the Code. Accordingly, and based upon the representations of Carbon and
CEC, in tax counsel's opinion, the exchange of CEC common stock for Carbon
common stock likely constitutes part of a tax-free Section 351 transaction. It
is possible that the IRS would view Yorktown's contribution of cash to Carbon
and the subsequent exchange as separate, unrelated events, in which case tax-
free treatment would be unavailable under Section 351 of the Code.

   Neither CEC nor Carbon has requested, nor will request, a ruling by the
Internal Revenue Service that the exchange of shares will be treated as tax
free. No assurance can be given that the Internal Revenue Service will not
challenge the tax-free nature of the exchange for U.S. federal income tax
purposes. If such a challenge were sustained by a court, each U.S. Shareholder
of CEC would recognize a capital gain or loss, assuming CEC is not a "passive
foreign investment company" (described below) to the extent of the difference
between the fair market value of the Carbon shares received by such
shareholder and such shareholder's tax basis of the CEC shares surrendered
therefor.

   If the exchange is tax-free as a B Reorganization or a Section 351
transaction, the following should be the material United States federal income
tax consequences of the exchange of CEC common shares for Carbon common
shares:

  .  You should not recognize gain or loss on the exchange of CEC common
     shares solely for Carbon common stock;

  .  The tax basis of the Carbon common stock received should be the same as
     the basis of the CEC common shares constructively surrendered in
     exchange therefor;

  .  The holding period for the shares of Carbon common stock should include
     the holding period of CEC common shares surrendered in exchange
     therefor; and

   Under Code Section 367(b) and the regulations thereunder, U.S. Shareholders
participating in the exchange are required to file an "exchange notice" with
the IRS. This exchange notice must be filed on or before the last date for
filing a federal income tax return (taking into account any extensions of time
for such filing) for the U.S. Shareholder's taxable year in which the exchange
takes place. The exchange notice must be filed with the IRS office with which
the U.S. Shareholder would be required to file a federal income tax return for
the year. This filing requirement will apply whether the exchange is treated
as tax-free B reorganization or a tax-free Section 351 transaction. You should
consult your tax advisors regarding the Section 367(b) exchange notice and its
required content.

                                      31


Passive Foreign Investment Company Considerations for U.S. Shareholders.

   For U.S. federal income tax purposes, CEC generally would be classified as
a Passive Foreign Investment company, or PFIC, for any taxable year during
which either: (1) 75 percent or more of its gross income is passive income, as
defined for U.S. federal income tax purposes; or (2) on average for such
taxable year, 50 percent or more of its assets by value produce or are held
for the production of passive income. The classification of CEC as a PFIC
could have adverse tax consequences with respect to the exchange that may be
substantial for U.S. Shareholders. However, CEC has represented that the
factual conditions that give rise to PFIC status have not existed with respect
to CEC during any taxable year ending at or prior to consummation of the
exchange. Therefore, based on this factual representation, the PFIC rules will
not affect U.S. Shareholders who participate in the exchange.

Taxation of Non-U.S. Shareholders.

   The following discussion applies to you if you are a non-U.S. Shareholder:

  .  who holds CEC common shares or will hold Carbon common stock as capital
     assets within the meaning of Section 1221 of the Code;

  .  who does not actually or constructively own, nor at any time in the
     preceding five-year period actually or constructively owned, five
     percent or more of the stock of CEC;

  .  whose ownership, receipt or disposition of CEC common shares and/or
     Carbon common stock is not attributable either to the conduct of a trade
     or business in the United States or to a permanent establishment in the
     United States; and

  .  who are not residents of the United States for purposes of United States
     federal income tax law or an income tax treaty to which the United
     States is a party.

   If you are a non-U.S. Shareholder who does not meet one or more of the
foregoing criteria, you are urged and expected to consult your own tax
advisors regarding your particular U.S. federal income tax consequences.

   Generally, you will not be subject to U.S. federal income tax on gain
recognized, if any, upon the exchange of the shares of CEC common shares for
the shares of Carbon common stock, unless:

  .  the gain is effectively connected with the conduct of a trade or
     business within the United States by you;

  .  the gain is attributable to a permanent establishment in the United
     States;

  .  if you are a nonresident alien and hold CEC common shares as a capital
     asset, you are present in the United States for 183 or more days in the
     taxable year and certain other circumstances are present; or

  .  you are subject to tax pursuant to the provisions of the Code applicable
     to some United States expatriates.

   Generally, dividends received by you with respect to Carbon common stock
will be subject to United States withholding tax at a rate of 30 percent,
which rate may be subject to reduction by an applicable income tax treaty. For
example, 15 percent is the applicable rate with respect to dividends paid to
residents of Canada who qualify for the benefits of the income tax treaty
between the U.S. and Canada. If the dividends you receive are effectively
connected with the conduct of a U.S. trade or business or are attributable to
a permanent establishment in the U.S. of yours, they will be taxed at the
graduated rates that are applicable to U.S. citizens, resident aliens and
domestic corporations and will not be subject to United States withholding tax
if you give an appropriate statement to the withholding agent in advance of
the dividend payment. A non-U.S. Shareholder that is a corporation may be
subject to an additional branch profits tax on effectively connected
dividends.

   Generally, foreign persons are not subject to U.S. federal income tax on
gain recognized, if any, upon the sale of shares of U.S. companies. However,
the gain on such sales can be taxable, including gain on the sale of Carbon
common stock, if:

  .  the gain is effectively connected with conduct of a trade or business
     within the United States;

                                      32


  .  you are a nonresident alien individual and hold the Carbon common stock
     as a capital asset, you are present in the United States for 183 or more
     days in the taxable year and other specific circumstances are present;

  .  you are subject to tax pursuant to the provisions of the Code applicable
     to U.S. expatriates; or

  .  Carbon likely is or will be a "United States real property holding
     corporation," a "USRPHC," for federal income tax purposes, as such term
     is defined by Section 897(c) of the Code. If Carbon is a USRPHC, then
     the gain from the disposition of its stock by a non-U.S. shareholder can
     be taxable in the United States. However, if Carbon's common stock is
     regularly traded on an established securities market, within the meaning
     of Section 897(c)(3) of the Code, an exception to this gain recognition
     rule is available. Carbon believes that as of the date of the exchange,
     Carbon common stock will be treated as being traded on an established
     exchange. However, this exception is available to non-U.S. shareholders
     only if the non-U.S. shareholder has not owned, directly or indirectly,
     pursuant to attribution rules, more than 5% of the Carbon stock at any
     time during the five-year period ending on the date of the disposition.

Estate Tax for Non-U.S. Shareholders.

   Carbon common stock owned, or treated as such, by an individual may be
includible in his or her gross estate for United States federal estate tax
purposes and thus if you are an individual you may be subject to United States
federal estate tax, unless an applicable estate tax treaty provides otherwise.

Information Reporting and Backup Withholding.

   Carbon must report annually to the IRS and to you and all other
shareholders the amount of dividends paid that year, and the tax withheld with
respect to such dividends, if any. These information reporting requirements
apply regardless of whether withholding tax is reduced by an applicable income
tax treaty. Copies of these information returns reporting such dividends and
withholding are made available to the tax authorities in the country in which
a non-U.S. Shareholder resides under the provisions of an applicable income
tax treaty or other agreement with the tax authorities in that country.

   In general, information reporting requirements may apply to dividend
distributions on Carbon common stock, or the proceeds of a sale, exchange,
retraction or redemption of Carbon common stock. A 31% backup withholding tax
may apply to these payments unless you are a corporation, non-U.S. Shareholder
or come within specific exempt categories and, when required, demonstrate your
exemption or provide a correct taxpayer identification number, certify as to
no loss of exemption from backup withholding and otherwise comply with
applicable requirements of the backup withholding rules. If you are required
to provide your correct taxpayer identification number and fail to do so, you
may be subject to penalties imposed by the IRS.

   United States backup withholding tax generally will not apply to dividends
paid on Carbon common stock that are subject to the 30% or reduced treaty rate
of withholding previously discussed if the beneficial owner certifies its non-
U.S. status under penalties of perjury, otherwise establishes an exemption or,
with respect to payments made after December 31, 1999, satisfies certain
documentary evidence requirements for establishing that it is a non-U.S.
holder. Under current law, dividends paid on Carbon common stock to you at an
address outside the United States are generally exempt from backup withholding
tax, but not from 30% withholding tax, as discussed above.

   On October 14, 1997 the IRS issued final regulations which affect your
United States taxation. Under these regulations, for dividends paid after
December 31, 1999, a non-United States person must generally provide proper
documents indicating their status to a withholding agent in order to avoid
backup withholding tax. However, dividends paid to exempt recipients, not
including individuals, will not be subject to backup withholding even if such
documentation is not provided, if the withholding agent is allowed to rely on
certain presumptions concerning the recipient's non-United States status (i.e.
payment to an address outside the United States).

                                      33


   If you are a non-U.S. Shareholder, payments of proceeds from the sale of
Carbon common shares by you made to or through a non-United States office of a
broker generally will not be subject to information reporting or backup
withholding. However, payments made to or through a non-United States office
of a United States broker or a non-United States office of a non-United States
broker that has certain specified connections with the United States, are
generally subject to information reporting, but not backup withholding unless
you certify your non-United States status under penalties of perjury or
otherwise establish your entitlement to an exemption. Payments of proceeds
from the sale of Carbon common stock by you made to or through a U.S. office
of a broker are generally subject to both information reporting and backup
withholding at a rate of 31% unless you certify your non-United States status
under penalties of perjury or otherwise establish your entitlement to an
exemption.

   Any amounts withheld under the backup withholding rules from a payment to
you will be allowed as a credit against your United States federal income tax,
provided that the required information is furnished to the IRS.

   Under Code Section 367(b) and the regulations thereunder, non-U.S.
Shareholders participating in the exchange might technically be required to
file an "exchange notice" with the IRS. You should consult your tax advisors
regarding the Section 367(b) exchange notice, its timing, its required
content, and the effect of failure to file such notice.

                   CANADIAN FEDERAL INCOME TAX CONSEQUENCES

   Subject to the qualifications and assumptions contained herein in the
opinion of Bennett Jones, Canadian counsel to CEC, the following is a general
summary of the material Canadian federal income tax consequences generally
applicable to holders of CEC common stock who dispose of CEC common stock
pursuant to the exchange offer. This summary:

      (i) is based on the current provisions of the Income Tax Act (Canada)
  (the "Canadian Tax Act"), the regulations thereunder (the "Regulations")
  and counsel's understanding of the current administrative practices of
  Revenue Canada, Customs, Excise and Taxation. This summary also takes into
  account the amendments to the Canadian Tax Act and Regulations publicly
  announced by the Canadian Minister of Finance prior to the date hereof (the
  "Proposed Amendments") and assumes that all such Proposed Amendments will
  be enacted in their present form. However, no assurances can be given that
  the Proposed Amendments will be enacted in the form proposed, or at all.
  Except for the foregoing, this summary does not take into account or
  anticipate any changes in law, whether by legislative, administrative or
  judicial decision or action, nor does it take into account provincial,
  territorial or foreign income tax legislation or considerations, which may
  differ from the Canadian federal income tax consequences described herein;
  and

       (ii) applies only to persons who, within the meaning of the Canadian
  Tax Act, acquire, hold and dispose of CEC common stock and Carbon common
  stock as capital property, deal at arm's length with CEC and Carbon and are
  not "financial institutions" for the purposes of the mark-to-market rules.
  CEC common stock and Carbon common stock will generally be considered to be
  capital property to a holder thereof provided that the holder does not hold
  any such shares in the course of carrying on a business of buying and
  selling shares and has not acquired such shares in a transaction considered
  to be an adventure in the nature of trade. Certain holders who are resident
  in Canada and who might not otherwise be considered to hold CEC common
  stock as capital property may be entitled to have such shares treated as
  capital property by making the election provided by subsection 39(4) of the
  Canadian Tax Act.

                                      34


   The tax consequences of the exchange will in all likelihood differ from one
holder to the next. Therefore, we urge you to consult your tax advisor
regarding the tax consequences unique to your situation.

Holders Resident in Canada

   The following portion of the summary is applicable only to holders of CEC
common stock who are resident or deemed to be resident in Canada for the
purposes of the Canadian Tax Act (a "Canadian Holder").

 Disposition of CEC Common Stock

   On the exchange of CEC common stock for Carbon common stock, a Canadian
Holder will be considered to have disposed of the CEC common stock for
proceeds of disposition equal to the fair market value at the time of the
exchange of the Carbon common stock received by the holder. A Canadian Holder
will realize a capital gain or capital loss, as appropriate, equal to the
amount by which such proceeds of disposition, net of any reasonable costs
associated with the disposition, exceed or are less than, as appropriate, the
holder's adjusted cost base of the CEC common stock. The cost to the Canadian
Holder of the Carbon common stock received by such holder will be equal to the
fair market value of such shares at the time of the exchange. The computation
of the adjusted cost base of Carbon common stock is discussed below in this
section under the heading "Disposition of Carbon Common Stock." The general
tax treatment of capital gains and losses is discussed in this section under
the heading "Capital Gains and Losses."

 Disposition of Carbon Common Stock

   A disposition or deemed disposition by a Canadian Holder of Carbon common
stock will generally give rise to a capital gain or capital loss, as
appropriate, equal to the amount by which the proceeds of disposition of the
Carbon common stock, net of any reasonable costs associated with the
disposition, exceed or are less than, as appropriate, the holder's adjusted
cost base of the Carbon common stock. In that regard, the cost to the holder
of the Carbon common stock acquired on the exchange will be averaged with the
adjusted cost base of any other Carbon common stock then owned by such holder
as capital property for the purposes of determining the adjusted cost base of
such Carbon common stock. The general tax treatment of capital gains and
losses is discussed below in this section under the heading "Capital Gains and
Losses".

 Capital Gains and Losses

   A Canadian Holder's taxable capital gain or allowable capital loss from the
disposition of CEC common stock or Carbon common stock will be equal to three-
quarters of the amount of the holder's capital gain or capital loss, as
appropriate, in respect of such disposition. A Canadian Holder must include
any such taxable capital gain in income for the taxation year of disposition,
and may, subject to the detailed provisions of the Canadian Tax Act, deduct
any such allowable capital loss from taxable capital gains in the year in
which such allowable capital loss is realized. Subject to the detailed rules
contained in the Canadian Tax Act, any remaining allowable capital loss may
generally be applied to reduce net taxable gains realized by the holder in the
three preceding and in all subsequent taxation years.

   If a Canadian Holder is a corporation, the amount of any capital loss
arising from a disposition or deemed disposition of CEC common stock or Carbon
common stock may be reduced by the amount of dividends received or deemed to
have been received by it on such shares to the extent and under circumstances
prescribed by the Canadian Tax Act. Similar rules may apply where a
corporation is a member of a partnership or a beneficiary of a trust that owns
CEC common stock or Carbon common stock.

   Capital gains realized by a Canadian Holder who is an individual may be
subject to alternative minimum tax under the Canadian Tax Act, depending on
the individual's circumstances.

   A Canadian Holder that is a "Canadian-controlled private corporation," as
defined in the Canadian Tax Act, may be liable to pay an additional refundable
tax of 6 2/3% on certain investment income, including amounts in respect of
taxable capital gains.

                                      35


 Eligibility for Investment

   The Carbon common stock issued pursuant to the offer, when listed on a
prescribed stock exchange, which includes the American Stock Exchange, will be
qualified investment under the Canadian Tax Act for trusts governed by
registered retirement savings plans, registered retirement income funds and
deferred profit sharing plans. However, such shares will constitute "foreign
property," as defined in the Canadian Tax Act, for the purposes of such plans.

 Subsequent Transaction

   As described in "The Exchange Offer--Second Step Merger", Carbon may, in
certain circumstances, merge CEC with a wholly-owned Canadian subsidiary of
Carbon (the "Second Step Merger"). The consequences under the Canadian Tax Act
to a holder whose CEC common stock is not exchanged under the exchange offer
and is disposed of in connection with the Second Step Merger will depend upon
the circumstances of the merger including, without limitation, the
consideration received by the holder and the person from whom such
consideration is received.

   If a holder receives Carbon common stock or cash in consideration for the
disposition of CEC common stock to Carbon, the holder will realize a capital
gain (or a capital loss) to the extent that the proceeds received for such
common stock, net of any reasonable costs associated with the disposition,
exceed (or are less than) the adjusted cost base of the CEC common stock
disposed of.

   If in the course of the Second Step Merger, CEC common stock is acquired by
CEC from an individual holder (including upon the exercise by an individual
holder of certain dissent rights), the individual holder will be deemed to
have received a taxable dividend in the amount by which the amount received
(other than in respect of interest awarded by a Court) exceeds the paid-up
capital of such CEC common stock. This amount will be excluded from the former
individual holder's proceeds of disposition for the purposes of computing any
taxable gain on the disposition. If the former individual holder is a resident
of Canada, the deemed dividend will be treated in the same manner as a regular
taxable dividend received from CEC. Corporations or trusts or partnerships
which have corporations as beneficiaries or partners should consult their own
tax advisors with respect to the income tax consequences where CEC common
stock is acquired by CEC.

   Upon the merger of CEC and a wholly-owned Canadian affiliate of Carbon, the
Canadian Tax Act deems the CEC common stock to be disposed of and the shares
of the amalgamated corporation to be acquired for an amount equal to the
adjusted cost base to the former holders of the CEC common stock.
Consequently, no capital gain or capital loss would be realized by the former
holders upon such amalgamation. A subsequent disposition of the shares of the
amalgamated corporation acquired on the amalgamation may give rise to a
capital gain, a capital loss, or if such shares are repurchased by the
amalgamated corporation, a deemed dividend. If on such amalgamation the former
holder receives property other than shares of the amalgamated corporation
(such as Carbon shares or cash) or exercises a dissent right pursuant to the
Alberta Business Corporations Act and receives cash in consideration for his
CEC common stock, such former holder will have a capital gain (or a capital
loss) to the extent that the proceeds received for such CEC common stock
(other than in respect of interest awarded by a Court), net of any reasonable
costs associated with the disposition, exceed (or are less than) the adjusted
cost base of the CEC common stock disposed of by the former holder.

Holders Not Resident in Canada

   The following portion of the summary is applicable only to holders of CEC
common stock who are not and will not be resident nor deemed to be resident in
Canada for the purposes of the Canadian Tax Act and any applicable tax treaty
at any time they hold such shares, who do not use or hold and are not deemed
to use or hold their CEC common stock in carrying on a business in Canada, and
in the case of a holder who carries on an insurance business in Canada and
elsewhere, whose shares are not "designated insurance property" and are not
effectively connected with an insurance business carried on in Canada at any
time (a "Non-Resident Holder").

                                      36


   A Non-Resident Holder will not be subject to tax in respect of capital
gains realized on the disposition of CEC common stock provided that the CEC
common stock is not "taxable Canadian property" of the Non-Resident Holder
immediately before the exchange. The CEC common stock will not constitute
"taxable Canadian property" of a Non-Resident Holder provided that such shares
are listed on a prescribed stock exchange (which currently includes the
American Stock Exchange), and the holder, persons with whom such holder does
not deal at arm's length, or the holder together with all such persons, has
not owned (or had under option) 25% or more of the issued shares of any class
or series of the capital stock of CEC at any time within five years preceding
the date of the exchange, and the shares were not acquired in a transaction
which deemed them to be "taxable Canadian property."

   The Canadian federal income tax consequences to a Non-Resident Holder who
does not tender to the offer of the transactions described in this summary
under "Subsequent Transaction" may be substantially different than those
described above and may include, without limitation, the recognition of a gain
which is subject to tax in Canada and/or the receipt of deemed dividends
and/or interest which would be subject to Canadian withholding tax. If CEC
common stock ceases at any time to be listed on a prescribed exchange, the
stock will at that time be considered "taxable Canadian property" to the Non-
Resident Holder. Non-Resident Holders who are considering not tendering to the
exchange offer are urged to consult their tax advisors as to the potential
consequences to them of such transactions.

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION

   The following unaudited pro forma financial information is derived from the
historical financial statements of BFC and CEC. The historical financial
statements are adjusted to reflect the following:

   The Carbon Unaudited Pro Forma Condensed Balance Sheet as of June 30, 1999
has been prepared assuming that the acquisition of BFC was consummated on June
30, 1999 and the exchange offer of Carbon shares for CEC shares was
consummated on May 31, 1999. The Carbon Unaudited Pro Forma Statement of
Income for the twelve months ended December 31, 1998 has been prepared
assuming that the acquisition of BFC was consummated on January 1, 1998 and
the exchange offer of Carbon shares for CEC shares was consummated on December
1, 1997. The Carbon Unaudited Pro Forma Statement of Income for the six months
ended June 30, 1999 has been prepared assuming that the acquisition of BFC was
consummated on January 1, 1999 and the exchange offer of Carbon shares for CEC
shares was consummated on December 1, 1998.

   The historical financial statements of CEC were prepared in Canadian
dollars in accordance with Canadian generally accepted accounting principles.
CEC's historical balance sheet as of May 31, 1999 and statements of income for
the year ended November 30, 1998 and the six months ended May 31, 1999 have
been adjusted to present the results in accordance with United States
generally accepted principles and have been translated to U.S. dollars.

   The Unaudited Pro Forma Balance Sheet reflects the preliminary allocation
of the purchase price of the BFC acquisition to the assets and liabilities of
Carbon. This statement also reflects the preliminary allocation of the
exchange offer of Carbon shares for CEC shares to the assets and liabilities
of Carbon. The valuation of the exchange offer for pro forma purposes was
calculated using the average of the three quoted closing prices for CEC shares
prior and subsequent to the announcement date of the signing of the BFC
purchase and sales agreement. The final allocation of the purchase price for
the BFC acquisition and the CEC exchange and the resulting effect on
depreciation, depletion and amortization expense will differ from the
preliminary estimates because the final allocation will be based on the
purchase price allocation of assets and liabilities based upon adjustments to
the final purchase price.

   The Carbon Unaudited Pro Forma Financial Information should be read in
conjunction with the accompanying notes thereto, and the historical financial
statements and notes thereto for Carbon, BFC, and CEC included elsewhere in
this prospectus. The pro forma information presented is not necessarily
indicative of the financial position or results of operations that would have
actually occurred had the acquisition of BFC and the exchange offer of Carbon
shares for CEC shares been consummated on the dates previously assumed. The
pro forma information presented is not intended to be a projection of future
financial position or results of operation.

              NOTES TO UNAUDITED PRO FORMA FINANCIAL INFORMATION

   (a) To reflect the purchase of BFC stock for cash by Carbon.

   (b) Adjustment to reflect estimated acquisition and other deal costs of
$300,000 to be incurred by Carbon. Paid in capital reflective of Yorktown's
investment is $24,750,000.

   (c) Adjustment to eliminate the historical basis of BFC assets and to
reflect the adjusted basis of the assets acquired resulting from the purchase
method of accounting. The allocated basis of the BFC assets are $30,560,000
for oil and gas properties and $239,000 for furniture, equipment and other.

   (d) Adjustment to eliminate the historical basis of CEC assets and to
reflect the adjusted basis of the assets acquired resulting from the purchase
method of accounting. The allocated basis of the CEC assets are $9,955,000 for
oil and gas properties and $82,000 for furniture, equipment and other. Paid in
capital reflective of the CEC exchange is $6,688,000.

   (e) Adjustment to reflect the increase in deferred taxes resulting from the
exchange of CEC shares for Carbon shares. The purchase accounting adjustment
resulted in an increase in the difference of book basis over tax basis for the
CEC assets.

   (f) Adjustment to reflect the impact on historical depletion attributed to
the acquisition of BFC and the exchange offer to current CEC shareholders. The
depletion amounts were calculated on the units-of-production method based on
estimates of total proved reserves. Separate cost pools were established for
CEC and BFC due to accounting rules that require cost centers be established
on a country-by-country basis. Based on the preliminary purchase price
allocation and the discounted future net cash flows attributable to the CEC
and BFC properties calculated using November 30, 1998 oil and gas prices for
CEC and December 31, 1998 prices for BFC, a ceiling test deficit would exist
on the properties. As a result of improved oil and gas prices subsequent to
year-end, the CEC and BFC properties had a cushion for ceiling test purposes
using May 31, 1999 oil and gas prices for CEC and June 30, 1999 prices for
BFC. Depreciation on the liquids extraction plant and other assets are
calculated using the straight-line method and the underlying assets estimated
useful lives.

   (g) To adjust for the capitalization of certain items under the full cost
method of accounting utilized by Carbon as compared to the successful efforts
method utilized by BFC.

   (h) Between December 1998 and April 1999, CEC purchased producing oil and
gas properties and natural gas gathering and compression facilities in
Alberta, Canada. These acquisitions were accounted for as purchases and
considered material in the aggregate by management for pro forma disclosure
purposes. The results of operations are presented as though the acquisition
had occurred at the beginning of the period being reported on. Revenues and
expenses subsequent to the purchase dates have been included in the 1999
operating results of CEC and are not included in this column. These results of
operations are not indicative of the results that would have occurred if the
acquisitions had been in effect for the entire periods presented and are not
intended to be a projection of future results.

   (i) Adjustment to reflect bonuses of $200,000 related in large part to the
acquisition of BFC and the exchange offer for CEC.

                             INFORMATION ABOUT CEC

Overview of Business

   CEC is an independent oil and natural gas company incorporated on May 31,
1955 under the Business Corporations Act (Alberta) in Canada. CEC was acquired
by the former parent of Columbus Energy Corp. ("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. CEC
engages in the exploration, development and production of crude oil and
natural gas and acquires and develops leaseholds and other interests in oil
and gas properties in the provinces of Alberta and Saskatchewan. CEC owns
working interests in 16 oil wells located in Saskatchewan, Canada and 47
natural gas wells located in Alberta, Canada. CEC also has ownership interests
in a natural gas processing plant and several gas gathering and compression
systems in Alberta. Prior to the end of 1998, substantially all of CEC's oil
and gas properties were operated by other industry companies. With certain
acquisitions completed in fiscal 1999, CEC has increased the percent of oil
and gas

                                      41


properties which it operates. CEC's business strategy is to grow through
exploitation of existing oil and gas properties by development of proved non-
producing and proved undeveloped reserves; acquisitions of complementary
working interests in existing and adjacent properties; and optimization of
gathering, compression and processing facilities. CEC will also conduct oil
and gas exploration activities in its core area of operations. In addition CEC
will evaluate acquisition and merger opportunities in Canada and the United
States.

   CEC employs a staff of professional oil and gas engineers, geologists, land
personnel and accountants to direct this effort. CEC's principal office is
located at Suite 1605, 700 6th Avenue S.W., Calgary, Alberta, Canada T2P 0T8.
CEC also has a United States office located at 1700 Broadway, Suite 1150,
Denver, Colorado 80290.

CEC Management's Discussion and Analysis of Financial Condition and Results of
Operations

   The discussion below summarizes CEC's financial condition and results of
operations and should be read in conjunction with the financial statements and
related notes. The financial related comments contained in this section are
derived from financial statements prepared in accordance with Canadian GAAP.

                                      42


 Results of Operations--Nine Months Ended August 31, 1999 Compared to the Nine
 Months Ended August 31, 1998

   Revenues for the nine months ended August 31, 1999 totaled $3,463,000, a
46% increase from the prior year period. The increase was due primarily to
increased natural gas and plant liquid volumes, including production resulting
from CEC'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.

   Oil and Gas 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.

        Oil--$/Bbl.........................................  20.91  18.51   13%
        Plant liquids--$/Bbl...............................  15.34  14.69    4%


   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
barrels of oil equivalent ("boe") basis compared to the same period in 1998.

   CEC's continued success with the exploitation of properties acquired during
1999 and current development activity have 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 per barrel 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
amounts of freehold and gross overriding royalties. CEC is eligible for the
Alberta Royalty Tax Credit ("ARTC") which varies inversely with prevailing
prices for oil and gas sales in Alberta. For the first nine months of 1999 and
1998 the net Crown Royalty rate was 6%.

   Field Services Business Segments. CEC receives operating service revenue
generated by its share of processing fees at the Carbon field liquid
extraction plant. Because of CEC's acquisitions in the East Carbon area, the
amount of unrelated third party gas processed through the plant has declined,
resulting in a decline in field service revenue for 1999 relative to 1998.


                                      43


   Lease Operating Expense. 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
overall lower 1999 lease operating expenses on CEC's properties, including
acquired properties, and the fact that lease operating expenses for 1998 were
higher due to well workovers at CEC'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.

   CEC 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 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. General and administrative ("G&A")
expenses, net of third party reimbursements, for the first nine months of 1999
totaled $1,522,000, a $907,000 or 148% increase from the same period in 1998.
The increase in G&A expense was primarily due to the hiring of full time
employees, partially offset by a reduction in charges for management services
provided by Columbus Energy under a management contract which was terminated
March 31, l999.

   Depletion, Depreciation and Amortization Expense. 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
per 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.

   Interest Expense. 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". CEC's average interest rate for the first nine months of 1999 was
7.25%.

 Acquisitions

   In December 1998 CEC 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 CEC's working interest
ownership in the East Carbon Field from 33 1/3% to 64%. CEC 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, CEC 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. CEC 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.

                                      44


   In March 1999, CEC 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 CEC's working interest ownership in the East Carbon Field from 64%
to 97%. CEC estimates that as of March 1, 1999, the remaining proved reserves
before royalty of the 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, CEC 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 CEC's working interest ownership in the East Carbon
Fields from 97% to approximately 100%. CEC 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, CEC entered into the BFC Stock Purchase Agreement to
acquire all of the stock of BFC, a 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. The purchase price for the
stock of BFC is approximately $24,000,000, subject to adjustments, plus net
debt of approximately $6,500,000 remaining at BFC.

 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

   CEC has positive working capital, a history of strong cash flow from
operating activities relative to its modest market capitalization and has
secured a financing commitment with Canadian Imperial Bank of Commerce
("CIBC").

   The principal sources of CEC's funds are cash flows from operating
activities and available borrowings under CEC'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 increased 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 BFC 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 CEC'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 CEC's common stock partially offset by the issuance of
70,000 shares of CEC's common stock.

   In December 1998, CEC received a financing commitment from 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 CEC'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 BFC acquisition. "See Acquisitions." The revolving phase of the loan
will expire on April 30, 2000 and may be renewed by CIBC. If

                                      45


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. This loan is secured
by all of CEC's assets. 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, CEC 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
anticipates little or no current income tax liability based upon current and
anticipated 1999 activity. For 1998, federal and provincial taxes were
$41,000.

 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.

   CEC 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.

   CEC utilizes a service bureau for its accounting processing. The service
bureau has represented that the oil and gas accounting system utilized by the
service bureau is Year 2000 compliant. CEC 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 vendor has represented that the
software is Year 2000 compliant. CEC is also dependent upon personal computer
based software programs and files that may not be Year 2000 compliant. CEC has
set a revised deadline of November 1999, to be internally compliant with Year
2000 specifications.

                                      46


   Management expects costs for CEC to become Year 2000 compliant will not be
significant. CEC does not believe that any loss of revenue will occur as a
result of the Year 2000 problem. However, despite CEC's efforts to identify
and remedy Year 2000 problems, there may be related failures that disrupt
CEC's business temporarily. In addition, the timetable for CEC'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 CEC's hardware and software in accordance with
CEC's established schedule. There can be no guarantee that CEC's estimates
will prove accurate, and actual results could differ significantly because of
the non-compliance of third parties of business importance to CEC.

   Natural gas revenues in 1998 were 4% higher than in 1997. Natural gas
prices were 13% higher and natural gas sales volumes were 8% lower due to a
gas processing plant and compressor down time and normal well productivity
decline. Revenues from oil were 17% lower in 1998 compared to 1997 because of
a 29% decrease in oil prices, partially offset by a 17% increase in volume.
Natural gas processing plant liquids sales volumes declined slightly from 1997
to 1998 due to lower natural gas production. Revenues were lower due to lower
oil and natural gas liquids prices in 1998 versus 1997.

   Natural gas revenues for 1997 were 5% higher than 1996 because of 27%
higher average prices which more than offset 17% lower gas sales volume due to
well productivity decline. Revenues from oil were 55% higher in 1997 compared
to 1996 because of a 57% increase in sales volumes due to a new oil well.
Plant liquids sales volumes decreased 7% and natural gas liquids prices
increased 14% in 1997 compared to 1996.

   Royalty expense consists primarily of Crown royalties in addition to
freehold and gross overriding royalties. CEC is eligible for the ARTC that
varies inversely with prevailing prices for oil and gas sales in Alberta. For
1998 the net Crown royalty rate was 6% of oil and gas sales compared to 8% in
1997. This decrease was attributed to a 13% increase from 1997 to 1998 in the
gas sales price received by CEC coupled with a 4% decrease from 1997 to 1998
in the reference price used to calculate Crown royalty expense.

                                      47


   Field Services Business Segment. CEC receives operating service revenue
generated by its share of processing fees at the Carbon area liquid extraction
plant. CEC also processes its own gas, and that portion of the processing fee
revenue attributable thereto is not reported in this segment and offsets an
identical amount of process expense otherwise chargeable to lease operations.
The Carbon plant also processes gas of unrelated third parties which in 1998
amounted to approximately 37% of the plant's volumes and represents the
majority of field services profit.

   CEC also derives revenues and net cash flow from separate gathering and
compression facilities in which it has ownership. Amounts applicable to CEC's
own production have likewise been eliminated from both revenue and expense of
these operations.

   Lease Operating Expense. Lease operating expenses for 1998 were 22% as a
percentage of oil and gas sales compared to 17% for 1997 and 20% for 1996. The
increase in 1998 compared to 1997 is attributed to well workovers and a full
year of production of oil wells in CEC's Hoffer area and additional
compression in the East Carbon area. This increase was partially offset by
variable expense decreases related to production declines. Lease operating
expenses per boe sold were $2.92, $2.27 and $2.12 for 1998, 1997 and 1996,
respectively. This trend is attributed to increased well workovers and fixed
costs allocated to a declining production base.

   CEC 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 rather than a ratio of 10 to 1 which historically has approximated
price ratios. The latter ratio is used almost exclusively by Canadian public
companies. CEC's share of processing fees charged to its wells have been
deducted from its field services revenues where CEC's one-third Carbon plant
ownership is involved.

   Field netbacks which are commonly reported by Canadian energy companies
equate to oil and gas sales less royalties and lease operating expenses. CEC's
average field netback was $9.23/boe in 1998, $9.69/boe in 1997 and $7.68/boe
in 1996. If natural gas had been converted to oil using the Canadian practice
of a 10:1 ratio, then reported field netbacks would have been $13.45/boe in
1998, $14.32/boe in 1997 and $11.67/boe in 1996.

   General and Administrative Expenses. G&A expenses relate to the direct
costs of CEC which do not originate from either its operation of properties or
the providing of services. Historically CEC had incurred certain direct and
indirect G&A costs for management services provided by Columbus Energy. These
costs were primarily for labor, related benefits and other overhead costs. G&A
costs increased by $223,000 in 1998 compared to 1997 primarily due to the
hiring of full time employees, which was partially offset by a reduction in
Columbus expenses. The management agreement with Columbus was terminated on
March 31, 1999.

   Depreciation, Depletion and Amortization Expense. DD&A costs of oil and gas
assets are determined based upon the units of production method. Natural gas
gathering, compression and processing facilities are depreciated on a straight
line method. For 1998, the depletion rate of oil and gas properties was $4.02
per boe for CEC, compared to $3.01 per boe for 1997, and $2.15 per boe for
1996. The 1998 increase in the depletion rate was primarily due to a downward
adjustment to CEC's year end proved reserves. The above calculated amounts for
1998, 1997 and 1996 include $62,000, $33,000 and $30,000 respectively, for
estimated future site restoration costs.

   Interest Expense. Interest expense in 1998 compared and 1997 was minimal
due to the fact that the company maintained significant cash balances and no
borrowings.

 Exploration Activities

   Under the full cost method of accounting, all exploration costs associated
with continuing efforts to acquire or review prospects and outside geological
and seismic consulting work are capitalized. A total of $54,000 of exploration
costs were capitalized during 1998. These charges include seismic and
consulting costs in the

                                      48


Carbon, East Carbon and Harmon areas of Alberta. A total of $230,000 of
exploration costs were capitalized during 1997. These charges included seismic
costs in the Maxim area of Saskatchewan and in the East Carbon area of
Alberta. Exploration costs capitalized in 1996 were $181,000, primarily in the
Hoffer area of Saskatchewan and for seismic cost in the Carbon field.

 Income Taxes

   In 1997, CEC adopted CICA 3465, Income Taxes. Since 1993, CEC has paid
current taxes to Revenue Canada based on its taxable income after utilization,
to the extent allowed, of its tax pool carryforwards. Currently payable
taxable income for future periods is dependent upon the level and type of
capital expenditures that are incurred in these periods as well as percentage
limitations for utilization of existing tax pools. For 1998, current income
taxes are estimated to be $19,000. For the 1997 and 1996 fiscal years CEC paid
no current federal tax because additions to deductible property tax pools and
carryover balances were sufficient to result in no taxable income.

 Effects of Changing Prices

   The Canadian economy experienced considerable inflation during the late
1970's and early 1980's but in recent years inflation has been fairly stable
at relatively low levels. CEC, along with most other business enterprises, was
then and will be affected in the future by any recurrence of such inflation.
Changing prices, or a change in the Canadian dollar's purchasing power,
distorts the traditional measures of financial performance which are generally
expressed in terms of the actual number of dollars exchanged and do not take
into account changes in the purchasing power of the monetary unit. This
results in the reporting of many transactions over an extended period as
though the dollars received or expended were of common value, which does not
accurately portray financial performance.

   Inflation, as well as a recessionary period, can cause significant swings
in the interest rates that companies pay on bank borrowings. These factors are
anticipated to continue to affect CEC's operations both positively and
negatively for the foreseeable future.

   Oil and gas prices fluctuate over time as a function of market economics.
Refer to the price change table in the discussion "Oil and Gas Operations
Comparisons 1998, 1997 and 1996" for information on product price fluctuation
over the past three years. This table depicts the effect of changing prices on
CEC's revenue stream.

   Operating expenses have been relatively stable but are a critical component
of profitability since they represent a larger percentage of revenues when
lower product prices prevail. Competition in the industry can significantly
affect the cost of acquiring leases, although in recent years this factor has
been less important as more operators have withdrawn from active exploration
programs.

Properties

 Estimated Oil and Gas Reserve Quantities and Revenues

   The estimated reserve amounts and future net revenues for 1998 were
determined by Sproule Associates Limited, an independent geological and
petroleum engineering firm, and for 1997 and 1996 by Reed Ferrill &
Associates, an independent petroleum engineering firm. CEC owned only Canadian
reserves during the periods.

   CEC's reserves are sensitive to natural gas and oil sales prices and their
effect on economic production rates and are based on the spot market price in
effect at year end and the sales prices of long-term contracts in effect prior
to year-end.

   Price declines decrease reserve values by lowering the future net revenues
attributable to the reserves and reducing the quantities of reserves that are
recoverable on an economic basis. Price increases have the opposite effect. A
significant decline in prices of oil or natural gas could have a material
adverse effect on CEC's financial condition and results of operations.

   Proved developed reserves are proved reserves that are expected to be
recovered from existing wells using existing equipment and operating methods.
Proved undeveloped reserves are proved reserves that are expected to be
recovered from new wells drilled to known reservoirs on undrilled acreage for
which the existence and recoverability of such reserves can be estimated with
reasonable certainty, or from existing wells where a relatively major
expenditure is required to establish production.

   Future prices received from production and future production costs may
vary, perhaps significantly, from the prices and costs assumed for purposes of
these estimates. There can be no assurance that the proved reserves will be
developed within the periods indicated or that prices and costs will remain
constant. There can be no assurance that actual production will equal the
estimated amounts used in the preparation of reserve projections.

   The present values shown should not be construed as the current market
value of the reserves. The 10% discount factor used to calculate present
value, which is specified by the Securities and Exchange Commission, is not
necessarily the most appropriate discount rate, and present value, no matter
what discount rate is used, is materially affected by assumptions as to timing
of future production, which may prove to be inaccurate. For properties
operated by CEC, expenses exclude CEC's share of overhead charges. In
addition, the calculation of estimated future net revenues does not take into
account the effect of various cash outlays, including among other things
general and administrative costs and interest expense.

   There are numerous uncertainties inherent in estimating quantities of
proved reserves and in projecting future rates of production and timing of
development expenditures. Oil and natural gas reserve engineering must be
recognized as a subjective process of estimating underground accumulations of
oil and natural gas that cannot be measured in an exact way, and estimates of
other engineers might differ materially from those shown above. The accuracy
of any reserve estimate is a function of the quality of available data and
engineering and geological interpretation and judgment. Results of drilling,
testing and production after the date of the estimate may justify revisions.
Accordingly, reserve estimates are often materially different from the
quantities of oil and natural gas that are ultimately recovered. The
meaningfulness of such estimates depends primarily on the accuracy of the
assumptions upon which they were based. In general, the volume of production
from oil and gas properties CEC owns declines as reserves are depleted. Except
to the extent CEC acquires additional properties containing proved reserves or
conducts successful exploration and development activities or both, the proved
reserves will decline as reserves are produced.

 Proved Developed Producing Reserves

   At November 30, 1998, CEC had approximately 3.9 billion cubic feet of
proved developed producing gas reserves which represents 65% of CEC's total
proved gas reserves. CEC also has approximately 144,000 barrels of oil and
81,000 barrels of natural gas liquids catagorized as proved developed
producing reserves which together represent 70% of CEC's total proved oil
reserves.

 Proved Developed Non-Producing Reserves

   At November 30, 1998, CEC had approximately 500 million cubic feet of
proved developed non-producing gas reserves representing 9% of its total
proved gas reserves. CEC's oil and liquids reserves in this category are
approximately 60,000 barrels or 19% of its total proved oil reserves.

   The reserves in this category are primarily reserves behind the casing in
existing wells and recompletion of those zones will be required to place them
on production. Also included are any wells which have been completed and were
awaiting connection to a gas pipeline as of year end, provided such pipeline
connection does not require significant investment.

 Proved Undeveloped Reserves

   At November 30, 1998, CEC's proved undeveloped reserves total approximately
1.6 billion cubic feet of gas, or 26% of its total proved natural gas
reserves, and approximately 38,000 barrels of oil and liquids, or 11% of its
total proved oil reserves.

   These reserves are attributable to wells which have been completed and were
awaiting pipeline connection as of the end of the year where such pipeline
connection would require significant investment and also undrilled locations
offsetting production in the Carbon, East Carbon, Harmon and Rowley areas of
Alberta.

                                      51


 Probable Reserves

   At November 30, 1998, CEC's probable natural gas reserves are approximately
600 million cubic feet. CEC's oil and natural gas liquids reserves in this
category are approximately 6,000 barrels.

   The reserves in this category are primarily reserves which may reasonably
be assumed to exist because of geophysical or geological indications and
drilling performed in the regions which contain proven reserves. The reserves
in this category are not included in the schedule of Standardized Measure of
Discounted Future Net Cash Flow (the "Standardized Measure").

 Comparison of Proved Reserves

   The decrease in proved developed producing reserves from 1997 to 1998 is
primarily due to 1998 production. The majority of the decrease in proved
developed non-producing and proved undeveloped reserves is due to the
following factors:

   The unsuccessful completion of a well in the East Carbon area resulted in
more stringent reservoir engineering interpretations of log characteristics
and analogous production in two natural gas zones. The unsuccessful completion
also disproved a geological hypothesis that was formerly presumed in the
determination of proved undeveloped reserves in these two natural gas zones.

   In 1998, a zone in the East Carbon area was remapped due to new offset well
information, resulting in geologic interpretations that did not support the
assignment of proved reserves for a location.

 Standardized Measure

   The Standardized Measure schedule is presented below pursuant to the
disclosure requirements of the Securities and Exchange Commission and
Statement of Financial Accounting Standards No. 69, "Disclosures About Oil and
Gas Producing Activities" (SFAS 69). Future cash flows are calculated using
year-end oil and gas prices and operating expenses, and are discounted using a
10% discount factor.

   Under SEC guidelines, Future Net Revenues shown below must be calculated
using prices that were in effect on November 30 of each year and are projected
forward based on existing contracts or the spot market price on that date.
Accordingly, the Future Net Revenues have been calculated using the spot
market sales price in effect at year end and the sales prices of long-term
contracts in effect prior to year end.

                                      52


   The prices utilized in this calculation for Future Net Revenues at November
30, 1998 are summarized as follows:


                                      
             Natural Gas
             1998....................... $    2.80/mcf
             1999.......................      2.69/mcf
             2000.......................      2.60/mcf
             2001.......................      2.58/mcf
             2002-forward...............      2.49/mcf
             Ngl........................ $12.67/barrel
             Oil........................ $16.94/barrel


   The standardized measure is intended to provide a standard of comparable
measurement of CEC's estimated proved oil and gas reserves based on economic
and operating conditions existing as of November 30, 1998, 1997 and 1996.
Pursuant to SFAS 69, the future oil and gas revenues are calculated by
applying to the proved oil and gas reserves the oil and gas prices at November
30 of each year relating to such reserves. Future price changes are considered
only to the extent provided by contractual arrangements in existence at year
end. Production and development costs are based upon costs at each year end.
Future income taxes are computed by applying statutory tax rates as of the
year end with recognition of tax basis, resource allowance, tax pool
carryforwards and earned depletion carryforwards as of that date and relating
to the proved properties. Discounted amounts are based on a 10% annual
discount rate. Changes in the demand for oil and gas, price changes and other
factors make such estimates inherently imprecise and subject to revision.

   As required by SFAS 69, the tax computation does not consider CEC's annual
interest expense and general and administrative expenses or future drilling
and equipment costs. Because of these factors, the tax provisions shown do not
represent the much lower future tax expense expected as long as CEC remains an
active operating company.

   Natural gas is converted to oil at the ratio of six mcf of natural gas to
one barrel of oil. Production costs include only lease operating expenses.

   Gas sales are generally made pursuant to gas purchase contracts with
unrelated third parties. Our gas sales are subject to price adjustment
provisions of the gas purchase contracts as well as general economic and
political conditions affecting the production and price of natural gas.

 Current Operations Activity

   CEC engages in the exploration, development and production of crude oil and
natural gas and acquires and develops leaseholds and other interests in oil
and gas properties in the provinces of Alberta and Saskatchewan. CEC owns
working interests in 16 oil wells located in Saskatchewan, Canada and 47
natural gas wells located in Alberta, Canada. CEC also has ownership interests
in a natural gas processing plant and several gas gathering and compression
systems in Alberta. Prior to the end of 1998, substantially all of CEC's oil
and gas properties were operated by other industry companies. With certain
acquisitions completed in fiscal 1999, CEC has increased the percent of oil
and gas properties which it operates. CEC's business strategy is to grow
through exploitation of existing oil and gas properties by development of
proved non-producing and proved undeveloped reserves; acquisitions of
complementary working interests in existing and adjacent properties; and
optimization of gathering, compression and processing facilities. CEC will
also conduct oil and gas exploration activities in its core area of
operations. In addition CEC will evaluate acquisition and merger opportunities
in Canada and the United States.

Financial Condition and Results of Operations"--"Acquisitions."

Legal Proceedings

   There are no material legal proceedings pending or, to our knowledge,
threatened against CEC.

Changes in and Disagreements with Accountants on Accounting and Financial
Disclosure

   PricewaterhouseCoopers LLP were engaged as CEC's independent auditors for
the 1998 fiscal year. On April 16, 1999, CEC, upon approval of its Board of
Directors, determined that the appointment of PricewaterhouseCoopersLLP should
not be renewed and that Arthur Andersen LLP should be proposed to CEC's
shareholders as its independent auditors for the 1999 fiscal year. The
President and Chief Executive Officer of CEC, as well as the Chief Financial
Officer, both of whom joined CEC during the last half of 1998, have a previous
relationship with Arthur Andersen LLP as a result of work at another oil and
gas company. In addition for fiscal 1999, Arthur Andersen LLP proposed a fee
structure for the year end audit, quarterly reviews and accounting
consultation that was economically beneficial to CEC.

   During CEC's two most recent fiscal years and subsequent interim period
preceding this determination, there were no disagreements with the former
auditors on any matter of accounting principles or practices, financial
statement disclosure or auditing scope or procedure. The auditors' report
during CEC's two most recent fiscal years preceding this determination did not
contain an adverse opinion or disclaimer of opinion and was not qualified or
modified as to uncertainty, audit scope or accounting principles.

Quantitative and Qualitative Disclosures about Market Risk

 Interest Rate Risk

   In 1999, CEC established a $6.5 million credit facility with a Canadian
bank as described in "CIBC Relationship" under "CEC Management's Discussion
and Analysis of Financial Condition and Results of Operations". The interest
rate for borrowings under this facility are variable.

 Foreign Currency Risk

   CEC's operations, except for certain administration functions performed in
its Denver, Colorado office, are conducted in Canada. CEC 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 "CEC Management's Discussion and Analysis of Financial
Condition and Results of Operations."

 Commodity Price Risk

   CEC uses certain financial instruments in an attempt to manage commodity
price risk. CEC attempts to manage these risks by minimizing its commodity
price exposure through the use of derivative contracts as described in Note 9
to the November 30, 1998 Financial Statements of CEC and Note 5 to the August
31, 1999 Financial Statements of CEC. Gains and losses on these contracts are
deferred and recognized in income as an adjustment to oil and gas sales
revenues during the period in which the physical product to which the
contracts relate is actually sold.

   Oil and gas commodity markets are influenced by global as well as regional
supply and demand. Worldwide political events can also impact commodity
prices. Management's policy is to mitigate its exposure to fluctuations in
sales prices received for natural gas production through the use of various
hedging tools. These tools include, but are not limited to: commodity futures
and option contracts; fixed-price swaps; basis swaps; and term sales
contracts. Contract terms generally range from one month to three years. While
we mitigate our exposure to declining natural gas sales prices, we may be
subject to lost opportunity costs resulting from increasing natural gas prices
in excess of those committed. Should production from existing facilities under
existing operating conditions not fulfill committed contracts, we may be
required to acquire natural gas in the open market, while volumes produced in
excess of those contracted are sold at market prices.

                           INFORMATION ABOUT CARBON

Business

   Carbon was incorporated on September 14, 1999 under the Colorado Business
Corporation Act and has its principal executive offices in Denver, Colorado.
Our business is currently comprised of the assets and properties of BFC, which
were acquired on October 29, 1999 in a stock purchase. On August 11, 1999, CEC
entered into a stock purchase agreement with BPC which provided for the
purchase by CEC from BPC of all outstanding shares of BFC for $23,857,951 in
cash, subject to certain adjustments.

   The purchase of BFC stock under the stock purchase agreement was completed
by Carbon rather than CEC. Rights and obligations of CEC under the stock
purchase agreement were assigned to Carbon. Yorktown purchased 4,500,000
shares of Carbon for $24,750,000. The funds from this purchase were used to
acquire the BFC shares under the stock purchase agreement and pay expenses
incurred in connection with the purchase and related transactions.

   As described above, we now own all of the stock of BFC. As the parent
company of BFC, we provide management and other services to BFC. Carbon itself
has not engaged in other activities, except for the acquisition of BFC and
preparations for the exchange offer made by this prospectus. BFC was an
independent oil and gas company engaged in the exploration, development, and
production of natural gas and crude oil. All of the properties and activities
described below were acquired or conducted by the prior management of BFC.
Through our acquisition of BFC, our activities are currently concentrated in
the Piceance and Uintah Basins in northwestern Colorado and eastern Utah, the
San Juan Basin in northwest New Mexico, the Permian Basin in southeast New
Mexico and western Texas, and southwestern Kansas. BFC owns working interests
in approximately 292 oil and gas wells, of which, approximately 190 wells are
operated by BFC. BFC employs a staff of oil and gas professionals to manage
its operations.

   Our oil and gas properties are located in the western United States and are
principally natural gas properties as discussed below and in "Properties."

 Piceance and Uintah Basins

   The Piceance and Uintah Basins have been core production areas since BFC's
inception. The productive formations are the Morrison, Dakota, Mancos, Castle
Gate, Mesa Verde and Wasatch formations. All of these formations produce
natural gas; however, in some areas, the Castle Gate sands formations are
known to contain oil reserves. We operate 132 wells and own working interests
in 146 wells in the Piceance Basin in Colorado and the Uintah Basin in Utah.
Carbon has not drilled any wells in these basins during 1999, however,
additional drilling locations have been identified for further analysis and
possible future drilling. We have leasehold rights in approximately 164,000
gross and 122,500 net acres of which approximately 41,500 gross and 37,500 net
acres are undeveloped.

 San Juan Basin

   Production in the San Juan Basin of northwest New Mexico is predominantly
natural gas. The primary productive formations on our acreage is the Dakota,
Gallup, Pictured Cliffs, and Fruitland (Coal Sands). We operate 41 wells and
own working interests in 42 wells in the San Juan Basin. We have lease rights
in approximately 5,200 gross and 2,600 net acres, all of which are developed.

 Permian Basin

   Our well interests in the Permian Basin are both operated and non-operated
in nature. We own working interests in 76 wells in the Permian Basin and
operate 11 of these wells. During 1999 we have participated in the drilling of
five wells, all of which were completed or are in the process of being
completed as producing gas wells. Additional wells are scheduled for drilling
during the balance of 1999. We have lease rights in approximately 23,500 gross
and 11,500 net acres, of which 1,400 gross and 1,000 net acres are
undeveloped.

                                      57


 Southwestern Kansas

   The main exploratory efforts of the company are concentrated in
southwestern Kansas. We own working interests in 28 wells and operate 4 wells
in this area. We are conducting regional geologic and geophysical work to
identify additional drilling prospects. We are also currently conducting
leasing to acquire acreage covering the most attractive prospects. We have
lease rights in approximately 33,000 gross and 25,500 net acres of which
30,000 gross and 24,500 net acres are undeveloped.

Carbon Selected Financial Data

Our Management's Discussion and Analysis of Financial Condition and Results of
Operations

   Our financial statements and related notes included in this prospectus are
those of our predecessor, BFC. The discussion below summarizes our financial
condition and results of operations and should be read in connection with the
financial statements and related notes of BFC.

 Results of Operations--Six Months Ended June 30, 1999 Compared to the Six
 Months Ended June 30, 1998

   The period-to-period comparisons set forth below are based upon the results
of operation of BFC under its prior management. As a result of that and the
anticipated acquisition of CEC through the exchange offer, we believe that the
period-to-period comparisons set forth below may not be indicative of our
future results of operation.

   Revenues for the first six months of 1999 totaled $14,728,000, a $6,702,000
or 84% increase from the prior year period amount of $8,026,000. The increase
was due primarily to higher natural gas production from existing wells and
newly drilled wells, from higher natural gas prices and increased marketing
service activity. Net income in the first six months of 1999 was $150,000
compared to net income of $596,000 in the first six

                                      58


months of 1998. The decrease in net income is primarily due to increased lease
operations expense, increased general and administrative expense and increased
exploration expense, partially offset by increased gas sales and increased
margins on marketing service activity.

   Oil and Gas Revenues. The following table shows comparative revenues, sales
volumes, average prices and percentage changes between periods, for natural
gas and oil for the first six months of 1999 and 1998.

        Oil--$/Barrel...................................  13.33  14.25    -6%


   Natural gas revenues for the first six months of 1999 increased 40% over
the first six months of 1998 because of a 10% price increase and a 32%
increase in sales volumes. The increase in sales volumes were primarily due to
successful drilling and recompletion results in various basins, particularly
in western Kansas and in the Permian Basin of New Mexico, partially offset by
production declines on existing properties. Oil revenues were 15% lower for
the first six months of 1999 compared to the first six months of 1998 because
of a 6% price decrease and a 9% decline in sales volumes.

   Average daily oil and gas production for the first six months of 1999
totaled 186 barrels of oil per day and 11,718 mcf of gas per day, an increase
of 27% on an barrel of oil equivalent basis (6:1) from the same period in
1998.

   Carbon's current drilling activity and continued success with the
exploitation of properties has resulted in increasing production for the first
six months of 1999. Exploitation and drilling activities are expected to
continue for the balance of 1999.

   Average oil prices decreased 6% from $14.25 per barrel in the first six
months of 1998 to $13.33 in 1999. Average natural gas prices increased 10%
from $1.76 per mcf for the first six months of 1998 to $1.94 per mcf in 1999.

   Oil and Gas Production Costs. Oil and gas production costs consist of lease
operating expense and severance taxes. Oil and gas production costs for the
first six months of 1999 were 42% as a percentage of oil and gas sales
compared to 39% for the first six months of 1998. Oil and gas productions
costs for the first six months of 1999 and 1998 were $4.98 and $4.47
respectively, per boe. The primary reason for the overall increase was the
accrual of natural gas gathering system well connect fees of $250,000 in 1999.
The fees are a result of a 1997 agreement which contained a contingency clause
whereby certain costs would be reimbursed to the party providing the well
connections if various production levels were not attained. These levels will
not be attained.

   Gas and Electrical Marketing. Gas and electrical marketing revenue
increased 127.5% in the first six months of 1999 compared to the first six
months of 1998. Gas and electrical marketing related expenses increased 120.9%
in the first six months of 1999 compared to the first six months of 1998. The
primary reason for the increase is a management contract in place during the
first quarter of 1999 for the purchase and sale of a high volume of natural
gas. The contract was not in place in the first quarter of 1998, and was
terminated on April 30, 1999.

                                      59


   General and Administrative Expenses. G&A expenses related to the direct
costs of BFC which do not originate from either its operation of properties or
the providing of services and are presented net of amounts billed to unrelated
third parties. G&A expenses increased by $520,000 for the first six months of
1999, compared to 1998. The primary reason for the increase is due to
increased staffing related to new capital programs.

   Depreciation, Depletion, Amortization and Impairment Expense. DD&A of oil
and gas assets are determined based upon the units of production method. This
expense is primarily dependent upon the historical capitalized costs incurred
to find, develop, and recover oil and gas reserves.

   For the first six months of 1999 the depletion rate was $3.42 per boe (6:1)
compared to $3.54 per boe for the first six months of 1998.

   For the first six months of 1999 impairment losses were $60,000, relating
to a property drilled in Oklahoma in 1998. There were no impairment losses
recorded for the first six months of 1998.

   Interest Expense. For the first six months of 1999, interest expense was
$251,000 compared to $85,000 for the first six months of 1998. The increase is
primarily due to higher levels of borrowing to finance drilling activity. BFC
capitalized $20,000 of interest in the first six months of 1999 which related
to calendar year 1998 interest charges and $44,000 of interest in the first
six months of 1999 related to drilling activity.

   Exploration Expense. Exploration expense was recorded under the successful
efforts method of accounting and primarily consists of unsuccessful drilling
costs and Geological and Geophysical ("G&G") costs.

   For the first six months of 1999 exploration expense was $638,000 compared
to $183,000 for the first six months of 1998. Unsuccessful drilling costs
amounted to $199,000 for the first six months of 1999 compared to $25,000 for
the first six months of 1998.

 Liquidity and Capital Resources

   Management considers our liquidity to be favorable compared to other oil
and gas companies based on the fact BFC has positive working capital and a
credit facility with U.S. Bank.

   The purpose of the loan is to provide financing for the acquisition of oil
and gas reserves and for normal operating requirements. The facility is
collateralized by certain oil and gas properties of the Company and is
scheduled to convert to a term note July 1, 2001. This term loan is scheduled
to have a maturity of either the economic half life of BFC's remaining
reserves on the date of the conversion, or July 1, 2006, whichever is earlier.
The borrowing base is based upon the lender's evaluation of BFC's proved oil
and gas reserves, generally determined semi-annually. The future minimum
principal payment under the term note will be dependent upon the bank's
evaluation of BFC's reserves at that time. The borrowing base was $16.9
million at June 30, 1999 with interest at a variable rate that approximated
6.70% at June 30, 1999. BFC has issued letters of credits totaling $2.5
million which further reduce the amount available for borrowing under the
base.

   In October, 1999, we sold 4,500,000 shares of our common stock to Yorktown
for $24,750,000 of which $23,857,951 was used to purchase the stock of BFC on
October 29, 1999 and the remaining proceeds have been added to our working
capital.

   For the six months ended June 30, 1999, net cash used in operating
activities was $1,529,000 compared to net cash provided by operating
activities of $2,092,000 for the same period in 1998. This decrease is
primarily due to changes in operating assets and liabilities. Cash used in
investing activities was $3,619,000 for the six months ended June 30, 1999
compared to $2,396,000 for the same period in 1998. This increase was
primarily due to additions of oil and gas properties. Net cash provided by
financing activities for the six months ended June 30, 1999 was $2,850,000 due
to an increase in net bank borrowings used to fund capital expenditures.


                                      60


   Income Taxes. Carbon accounts for income taxes under the liability method
which requires recognition of deferred tax assets and liabilities for the
expected future tax consequences of events that have been included in the
financial statements or tax returns. Under this method, deferred tax assets
and liabilities are determined based on the difference between the financial
statement and tax basis of assets and liabilities using enacted tax rates in
effect for the year in which the differences are expected to reverse. BFC's
operations were formerly included in BPC's consolidated tax return. Income
taxes were allocated to BFC as if BFC was a separate taxpayer.

   BFC has not accrued an estimate for income taxes for the six months ended
June 30, 1999 as it is anticipated that estimates of taxes due for the period
are offset by intangible drilling costs.

 Year 2000 Compliance

   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.

   Our company has made inquiries of the suppliers and manufacturers of its
computer systems, including equipment supplied by third parties, and has been
advised that such systems are Year 2000 compliant except for our property
management software that is currently under review regarding Year 2000
compliance.

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

(1) Exclusive of a production payment used to pay down a related note. Volumes
    attributed to this activity were 238,313 mcf in 1997 and 308,580 mcf in
    1996.

   Natural gas revenues for 1998 increased 13% compared to 1997 primarily due
to a 13% increase in sales volumes. Oil revenue for 1998 decreased 30%
compared to 1997 primarily due to a 32% decrease in sales prices. The
increases to sales volumes were primarily due to successful drilling and
recompletion activity, partially offset by production declines on previously
existing properties.

   Natural gas revenue for 1997 increased 29% compared to 1996 primarily due
to a 19% increase in sales volumes and a 9% price increase. Oil revenue for
1997 was essentially flat compared to 1996 as a 9% increase in sales volumes
was offset by 8% price decline. The increases in sales volumes were primarily
due to successful drilling and recompletion activity, partially offset by
production declines on previously existing properties.

   Oil and Gas Production Costs. Oil and gas production costs consist of lease
operating expense and severance taxes. Oil and gas production costs for 1998
were 44% as a percentage of oil and gas sales compared to 43% for 1997 and 40%
for 1996. Oil and gas production costs for 1998, 1997 and 1996 were $4.92,
$5.16 and $4.92 respectively, per boe. The increase in 1997 from 1996 was
largely the result of increased spending for environmental remediation
purposes. In addition, severance taxes increased 40% in 1997 compared to 1996.

   Gas and Electrical Marketing. Gas and electrical marketing revenue
increased 45% in 1998 compared to 1997 while gas and electrical marketing
expenses increased 53% in 1998 compared to 1997. Certain high margin contracts
expired early in 1997. The related margins were not present during most of
1997, nor in 1998.

   Gas and electrical marketing revenue increased 1% in 1997 compared to 1996
while related expenses increased 31% in 1997 compared to 1996. Certain high
margin contracts which were in effect in 1996, expired early in 1997. The
related margins were not present during most of 1997.

   General and Administrative Expenses. G&A expenses relate to the direct
costs of BFC which do not originate from either its operation of properties or
the providing of services and are presented net of amounts billed to unrelated
third parties. G&A expenses increased by $1,065,000 in 1998 compared to 1997.
In 1998 a court approved retention compensation accrual of $425,000 was
recorded. The remainder of the increase is primarily due to costs associated
with additional staffing related to anticipated increases in drilling
activity.

   G&A expenses increased by $118,000 in 1997 compared to 1996.

   DD&A Depreciation, Depletion, Amortization and Imparment Expense.
Depreciation, Depletion, Amortization and Impairment ("DD&A") of oil and gas
assets are determined based upon the units of production method. This expense
is primarily dependent upon historical capitalized cost incurred to find,
develop and recover oil and gas reserves.

   For 1998 the depletion rate was $3.42 per boe compared to $3.24 per boe in
1997 and $2.40 per boe in 1996. The increase in 1997 compared to 1996 was
primarily due to increased production from high DD&A properties and from an
additional $200,000 recorded in 1997 for future plugging and abandonment
charges.

   Impairment losses were $1,858,000 in 1998 compared to $312,000 in 1997. The
increase is primarily due to a decline in the estimated value of producing
properties due to oil and gas prices that were substantially lower at year end
1998 compared to year end 1997, and from downward revisions of previous oil
and gas reserve estimates. There were no recorded impairment losses in 1996.

   Interest Expense. Interest expense was $238,000 in 1998 compared to $83,000
in 1997 and $272,000 in 1996. The increase in 1998 is primarily due to
increased borrowings for drilling and development activity and because of
lower prices received from oil and gas sales. The decrease in interest expense
from 1997 compared to 1996 is primarily due to lower borrowings for drilling
and development activities.

                                      62


   Exploration Expense. Exploration expense was recorded under the successful
efforts method of accounting and consists primarily of unsuccessful drilling
costs and G&G costs. Exploration expense in 1998 was $556,000 compared to
$772,000 in 1997 and $419,000 in 1996. The amount related to unsuccessful
drilling was lower in 1998 compared to 1997, while G&G costs increased in 1998
compared to 1997 because of increased exploration activities. The amount
related to unsuccessful drilling was higher in 1997 compared to 1996, and G&G
costs increased in 1997 compared to 1996 because of increased exploration
activities.

   Income Taxes. BFC accounts for income taxes under the liability method
which requires recognition of deferred tax assets and liabilities for the
expected future tax consequences of events that have been included in the
financial statements or tax returns. Under this method, deferred tax assets
and liabilities are determined based on the difference between the financial
statement and tax bases of assets and liabilities using enacted tax rates in
effect for the year in which the differences are expected to reverse. BFC's
operations were formerly included in BPC's consolidated tax return. Income
taxes were allocated to BFC as if BFC was a separate taxpayer.

 Effects of Changing Prices

   The U.S. economy experienced considerable inflation during the late 1970's
and early 1980's but in recent years inflation has been fairly stable at
relatively low levels. BFC, along with most other business enterprises, was
then and will be affected in the future by any recurrence of such inflation.
Changing prices, or a change in the dollar's purchasing power, distorts the
traditional measures of financial performance which are generally expressed in
terms of the actual number of dollars exchanged and do not take into account
changes in the purchasing power of the monetary unit. This results in the
reporting of many transactions over an extended period as though the dollars
received or expended were of common value, which does not accurately portray
financial performance.

   Inflation, as well as a recessionary period, can cause significant swings
in the interest rates that companies pay on bank borrowings. These factors are
anticipated to continue to affect BFC's operations both positively and
negatively for the foreseeable future.

   Oil and gas prices fluctuate over time as a function of market economics.
Refer to the price change table in the discussion "Oil and Gas Operations
Comparisons for 1998, 1997 and 1996" for information on product price
fluctuation over the past three years. This table depicts the effect of
changing prices on BFC's revenue stream.

   Operating expenses have been relatively stable but are a critical component
of profitability since they represent a larger percentage of revenues when
lower product prices prevail. Competition in the industry can significantly
affect the cost of acquiring leases, although in recent years this factor has
been less important as more operators have withdrawn from active exploration
programs.

Properties

   We have approximately 234,000 gross acres and 152,000 net acres of land in
inventory. The majority of our proved reserves are concentrated in four
areas--the Piceance/Uintah Basins, the Permian Basin, the San Juan Basin and
Southwestern Kansas. All wells and acreage are located in the continental
United States.

 Estimated Oil and Gas Reserve Quantities and Revenues

   The estimated reserve amounts and future net revenues were determined by
Ryder Scott, an independent petroleum engineering firm, for 1998, 1997 and
1996.


                                      63


   BFC's reserves are sensitive to natural gas and oil prices and their effect
on future net revenues and the quantities of reserves that are recoverable at
economic producing rates are based on fixed price contracts or on the spot
market price in effect on December 31, 1998, 1997 and 1996.

   Price declines decrease reserve values by lowering the future net revenues
attributable to the reserves and reducing the quantities of reserves that are
recoverable on an economic basis. Price increases have the opposite effect. A
significant decline in prices of oil or natural gas could have a material
adverse effect on the company's financial condition and results of operations.

   Proved developed reserves are proved reserves that are expected to be
recovered from existing wells using existing equipment and operating methods.
Proved undeveloped reserves are proved reserves that are expected to be
recovered from new wells drilled to known reservoirs on undrilled acreage for
which the existence and recoverability of such reserves can be estimated with
reasonable certainty, or from existing wells where a relatively major
expenditure is required to establish production.

   Future prices received from production and future production costs may
vary, perhaps significantly, from the prices and costs assumed for purposes of
these estimates. There can be no assurance that the proved reserves will be
developed within the periods indicated or that prices and costs will remain
constant. There can be no assurance that actual production will equal the
estimated amounts used in the preparation of reserve projections.

   The present values shown should not be construed as the current market
value of the reserves. The 10% discount factor used to calculate present
value, which is specified by the Securities and Exchange Commission, is not
necessarily the most appropriate discount rate, and present value, no matter
what discount rate is used, is materially affected by assumptions as to timing
of future production, which may prove to be inaccurate. For properties
operated by BFC, expenses exclude BFC's share of overhead charges. In
addition, the calculation of estimated future net revenues does not take into
account the effect of various cash outlays, including among other things
general and administrative costs and interest expense.

   There are numerous uncertainties inherent in estimating quantities of
proved reserves and in projecting future rates of production and timing of
development expenditures. Oil and natural gas reserve engineering must be
recognized as a subjective process of estimating underground accumulations of
oil and natural gas that cannot be measured in an exact way, and estimates of
other engineers might differ materially from those shown above. The accuracy
of any reserve estimate is a function of the quality of available data and
engineering and geological interpretation and judgment. Results of drilling,
testing and production after the date of the estimate may justify revisions.
Accordingly, reserve estimates are often materially different from the
quantities of oil and natural gas that are ultimately recovered. The
meaningfulness of such estimates depends primarily on the accuracy of the
assumptions upon which they were based. In general, the volume of production
from oil and gas properties we own declines as reserves are depleted. Except
to the extent we acquire additional properties containing proved reserves or
conduct successful exploration and development activities or both, the proved
reserves will decline as reserves are produced.

 Proved Developed Producing Reserves

   At December 31, 1998, BFC had approximately 16.8 billion cubic feet of
proved developed producing gas reserves which represents 65% of BFC's total
proved gas reserves. BFC also had approximately 162,000 barrels of oil and
natural gas liquids of proved developed producing reserves which together
represent 98% of BFC's total proved oil reserves.

 Proved Developed Non-Producing Reserves

   At December 31, 1998, BFC had approximately 8.6 billion cubic feet of
proved developed non-producing gas reserves representing 33% of its total
proved gas reserves. BFC's oil and liquids reserves in this category are
approximately 3,800 barrels or 2% of its total proved oil reserves.

   The reserves in this category are primarily reserves for wells which have
been completed and were awaiting connection to a gas pipeline as of year end,
provided such pipeline connection does not require significant investment.
Also included are reserves behind the casing in existing wells and
recompletion of those zones will be reqired to place them on production.

 Proved Undeveloped Reserves

   At December 31, 1998, BFC's proved undeveloped reserves total approximately
517 million cubic feet of gas, or 2% of its total proved natural gas reserves,
and no barrels of oil and liquids.

   These reserves are attributable to wells which have been completed and were
awaiting pipeline connection as of the end of the year where such pipeline
connection would require significant investment and also undrilled locations
offsetting production in various fields.

 Probable Reserves

   At December 31, 1998, BFC's probable natural gas reserves are approximately
948 million cubic feet. BFC's oil and gas liquids reserves in this category
are approximately 6,400 barrels.


                                      65


   The reserves in this category are primarily reserves which may reasonably
be assumed to exist because of geophysical or geological indications and
drilling performed in the regions which contain proven reserves. The reserves
in this category are not included in the schedule of Standardized Measure of
Discounted Future Net Cash Flow (the "Standardized Measure").

 Comparison in Proved Reserves

   The following table compares BFC's estimated proved reserves as of December
31, 1997 and 1998.

   The decrease in proved developed producing reserves from 1997 to 1998 is
primarily due to 1998 production.

 Standardized Measure

   The Standardized Measure schedule is presented below pursuant to the
disclosure requirements of the Securities and Exchange Commission and
Statement of Financial Accounting Standards No. 69, "Disclosures About Oil and
Gas Producing Activities" (SFAS 69). Future cash flows are calculated using
year-end oil and gas prices and operating expenses, and are discounted using a
10% discount factor.

   Under SEC guidelines, Future Net Revenues shown below must be calculated
using prices that were in effect on December 31 of each year and are projected
forward based on existing contracts or the spot market price on that date.
Accordingly, the Future Net Revenues have been calculated using the
appropriate sales price in effect on December 31, 1998, 1997 and 1996.

   Oil and gas prices at December 31, 1998, 1997, and 1996 of $10.69, $16.91,
and $25.60, respectively, per barrel of oil and $1.84, $1.81, and $3.17
respectively, per mcf of gas were used in the estimation of BFC's reserves and
future net cash flows.

   The standardized measure is intended to provide a standard of comparable
measurement of BFC's estimated proved oil and gas reserves based on economic
and operating conditions existing as of December 31, 1998, 1997 and 1996.
Pursuant to SFAS 69, the future oil and gas revenues are calculated by
applying to the proved oil and gas reserves the oil and gas prices at December
31 of each year relating to such reserves. Future price changes are considered
only to the extent provided by contractual arrangements in existence at year
end. Production and development costs are based upon costs at each year end.
Future income taxes are computed by applying statutory tax rates as of the
year end with recognition of tax basis and earned depletion carryforwards as
of that date relating to the proved properties. Discounted amounts are based
on a 10% annual discount rate. Changes in the demand for oil and gas, price
changes and other factors make such estimates inherently imprecise and subject
to revision.

   As required by SFAS 69, the tax computation does not consider BFC's annual
interest expense and general and administrative expenses or future drilling
and equipment costs. Because of these factors, the tax provisions shown do not
represent the much lower future tax expense expected as long as BFC remains an
active operating company.

   Natural gas is converted to oil at the ratio of six mcf of natural gas to
one barrel of oil. Production costs include only lease operating expenses and
severance taxes.

   We operate most of the wells in which we own interests and also hold
working interests in some wells operated by third parties. Gas sales are
generally made pursuant to gas purchase contracts with unrelated third
parties. Our gas sales are subject to price adjustment provisions of the gas
purchase contracts as well as general economic and political conditions
affecting the production and price of natural gas.

Legal Proceedings

   There are no material legal proceedings pending or, to our knowledge,
threatened against us.

Changes in and Disagreements with Accountants on Accounting and Financial
Disclosure

   Hein + Associates, LLP audited BFC's consolidated financial statements for
the years ending December 31, 1992--1998. Management expects to engage Hein +
Associates to audit BFC's financial statements for the ten months ending
October 31, 1999. Carbon's new Board of Directors has appointed Arthur
Andersen LLP to be Carbon's accountants for the two month period ended
December 31, 1999.

Quantitative and Qualitative Disclosures about Market Risk

 Interest Rate Risk

   Our exposure to market risk for changes in interest rates relates primarily
to our long-term debt obligations. See Notes 3 and 10 to the December 31, 1998
Financial Statements of BFC.

 Foreign Currency Risk

   To date our cash flows have been in U.S. dollars only, negating the need to
hedge against any foreign currency risks.

 Commodity Price Risk

   BFC uses certain financial instruments in an attempt to manage commodity
price risk. BFC attempts to manage these risks by minimizing its commodity
price exposure through the use of derivative contracts as described in Note 6
to the December 31, 1998 Financial Statements of BFC. Gains and losses on
these contracts are deferred and recognized in income as an adjustment to oil
and gas sales revenues during the period in which the physical product to
which the contracts relate is actually sold.

   Oil and gas commodity markets are influenced by global as well as regional
supply and demand. Worldwide political events can also impact commodity
prices. Management's policy is to mitigate its exposure to fluctuations in
sales prices received for natural gas production through the use of various
hedging tools. These tools include, but are not limited to: commodity futures
and option contracts; fixed-price swaps; basis swaps; and term sales
contracts. Contract terms generally range from one month to three years. While
we mitigate our exposure to declining natural gas sales prices, we may be
subject to lost opportunity costs resulting from increasing natural gas prices
in excess of those committed. Should production from existing facilities under
existing operating conditions not fulfill committed contracts, we may be
required to acquire natural gas in the open market, while volumes produced in
excess of those contracted are sold at market prices.

(1) Options were originally granted to acquire CEC common stock at the closing
    price of CEC's common stock on the date of the grant. These options are
    being replaced with Carbon options on the same terms.

(2) These columns present hypothetical future realizable values of the
    options, obtainable upon exercise of the options net of the option's
    exercise price, assuming CEC's common stock appreciates at a 5% and 10%
    compound annual rate over the term of the options. The 5% and 10% rates of
    market price appreciation are presented as examples pursuant to rules of
    the SEC and do not reflect management's prediction of the future market
    price of our common stock. No gain to the optionees is possible without an
    increase in the market price of the common stock above the option price.
    There can be no assurance that the potential realizable values shown in
    this table will be achieved. The potential realizable values presented are
    not intended to indicate the value of the options.

   No options were exercised by CEC's President and Chief Executive Officer
during fiscal 1998. The following table summarizes information with respect to
the value of that officer's unexercised stock options at November 30, 1998:

(1) Options were granted by CEC to acquire its common stock. These options are
    replaced with options to acquire our stock.
(2) The in-the-money value of unexercised options is equal to the excess of
    the per share market price of CEC's stock at November 30, 1998 over the
    per share exercise price multiplied by the number of unexercised options.
    However, the per share exercise price was higher than the market price of
    CEC's stock at fiscal year end.

1999 Stock Option and Restricted Stock Plans

   Our 1999 Stock Option Plan was adopted by the directors as of October 14,
1999. Under the 1999 plan, we may grant options to purchase up to 700,000
shares of our common stock. Grants under the Stock Option Plan may consist of
(1) options intended to qualify as incentive stock options under the Internal
Revenue Code and (2) non-qualified stock options that are not intended to so
qualify. Persons eligible to receive incentive stock options under the plans
are only our employees; non-qualified stock options may be granted to
employees, directors and consultants. The Stock Option Plan terminates on
September 1, 2009.

   We also have a 1999 Restricted Stock Plan which was adopted by our Board of
Directors on October 14, 1999. The Restricted Stock Plan has 300,000 shares of
our common stock available for grants. Under the Restricted Stock Plan, the
administrator may issue shares of our common stock to the grantee, and those
shares are subject to restrictions and forfeiture in accordance with the terms
of a stock restriction agreement. Under the current form of agreement, the
restricted stock may be subject to vesting requirements and forfeiture of
unvested shares if the grantee ceases to be an employee or a member of the
Board of Directors, except as may be provided in an employment agreement.
Grants under the Restricted Stock Plan may be made to an employee, director or
consultant of our company or any subsidiary. The Restricted Stock Plan
terminates on September 1, 2009.

   Each plan is administered by the Board of Directors or a committee
appointed by the Board consisting of two or more non-employee directors and
our President. The Board or administrating committee determines the persons to
be granted options, the exercise price per share for each option, the
expiration date of each option and other terms which may be set forth in an
option agreement. Likewise, the Board or administrating committee determines
the persons to be granted restricted stock and nature of any forfeitures and
related restrictions regarding that stock. The Board of Directors currently
administers both plans.

   The exercise price of an incentive stock option granted under to the plans
cannot be less than 100% of the fair market value of the common stock on the
date of the grant. The Board determines the exercise price of a non-qualified
stock option; in the case of the 1999 plan, the exercise price of a non-
qualified stock option cannot be less than 85% of the fair market value of the
common stock on the date of grant. The term of any stock option cannot exceed
ten years. However, the exercise price of an incentive stock option granted to
any person who at the time of grant owns stock representing more than 10% of
the total combined voting power of all classes of our capital stock or any of
our affiliates must be at least 110% of the fair market value of our common
stock on the date of grant and the term of such an incentive stock option
cannot exceed five years. Options granted under the plans vest at the rate
specified in any option agreement. The exercise price may be paid in cash or
other shares of our common stock, as determined by the Board of Directors or
the administering committee.

   In the event of a proposed sale of all or substantially all our assets, or
the merger of Carbon with another corporation, or any other capital
reorganization in which persons who were stockholders of our company
immediately before the capital reorganization owned less than two-thirds of
the outstanding voting securities of the surviving company following the
capital reorganization, the plan administrator is to make appropriate
provisions for the protection of outstanding options by the substitution of
appropriate stock of our company or any surviving corporation or,
alternatively, our Board of Directors may terminate an outstanding option by
permitting the option to be exercisable as to all shares subject to the
option, whether or not previously vested, for a period of thirty days (or not
less than 10 days in the case of the 1999 plan) after a notice to the option
holder.

   All outstanding options under the 1999 plan become immediately exercisable
and full, whether or not there were vesting requirements, upon the occurrence
of a change in control. All restricted stock outstanding under the 1999
Restricted Stock Plan also become fully vested upon a change of control. For
this purpose, a change in control occurs (1) at the time a third person or
group becomes the beneficial owner of shares with 50% or more of the total
number of votes cast for the election of our directors; (2) on the date our
shareholders approve a merger or consolidation (unless our shareholders
continue to own after the merger or consolidation more than two-thirds of the
voting securities of the resulting corporation in substantially the same
proportion as their

                                      73


ownership of our voting securities before the merger or consolidation) or any
sale or other disposition of all or substantially all of our assets, or (3) a
sale or other disposition of more than 50% in fair market value of our assets
outside the ordinary course of business, or (4) if at the time there is a
change in more than a majority of our Board of Directors as a result of a
proxy contest (unless any option holder or the holder of restricted stock, as
the case may be, or the person's affiliate has waged the proxy contest or
endorsed the change in our Board). In determining whether clause (1) of this
definition has been satisfied, Yorktown and entities controlled by Yorktown
Partners LLC (the managing general partner of Yorktown) are excluded.

Directors' Compensation

   Each of our directors who is neither an officer nor an employee will be
paid a director's fee of $1,500 per quarter.

   Also, in consideration of their joining our Board of Directors, David
Kennedy and Lambros J. Lambros, who are considered to be independent
directors, each were granted on October 14, 1999, granted a nonqualified stock
option to purchase 10,000 shares of our common stock at $5.50 per share.
Shares subject to these options vest one-half on the first anniversary and
one-half on the second anniversary of the date of grant, and these options
have a ten-year term.

Indemnification and Limitation of Liability

   Our Bylaws provide that we will indemnify our directors and executive
officers and may indemnify our other officers, employees and other agents to
the fullest extent permitted by Colorado law. We have also entered into
indemnification agreements with each of our directors and executive officers.
All indemnification agreements are identical. These agreements provide, among
other things, for indemnification and advancement of expenses to the fullest
extent permitted by law in connection with any legal proceeding in which the
person was made a party because the person was a director or executive officer
of Carbon, place the burden of proof on us in regard to whether an individual
has met the required standard of conduct for indemnification, cover procedural
matters such as the hiring of counsel and require us to pay the expenses of
the director or executive officer in enforcing any required indemnification or
advancement of expenses.

   In addition, our Articles of Incorporation provide that to the fullest
extent permitted by Colorado law, our directors will not have personal
liability to us or our stockholders for monetary damages for any breach of
fiduciary duties as a director. This does not eliminate the duties themselves,
and in appropriate circumstances, equitable remedies such as injunction or
other forms of nonmonetary relief remain available under Colorado law. This
provision does not eliminate the liability of a director for (1) any breach of
the director's duty of loyalty to us or our stockholders; (2) acts or
omissions not in good faith or which involve intentional misconduct or a
knowing violation of law; (3) unlawful dividends, stock repurchases or
redemptions; or (4) any transaction from which the director derived an
improper personal benefit. This does not affect a director's responsibilities
under other laws such as the federal or state securities laws.

   There is no pending litigation or proceeding involving a director or
officer as to which indemnification is being sought. We are not aware of any
pending or threatened litigation that may result in claims for indemnification
by any director or officer.

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Securities Act") may be permitted to directors, officers or
persons controlling us pursuant to the foregoing provisions or otherwise, we
have been advised that in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Securities Act, and is, therefore, unenforceable.

Employment Agreement

   On October 31, 1999, we entered into a three-year employment contract with
Mr. McDonald. The employment agreement with Mr. McDonald is described under
"The Exchange Offer--Interests of Certain Persons in the Exchange Offer."

                     CERTAIN RELATIONSHIPS AND TRANSACTIONS

   In October 1999, Yorktown purchased an aggregate of 4,500,000 shares of our
common stock for $24,750,000 in cash. Also, in October, 1999, each of our two
independent directors, Messrs. Kennedy and Lambros, purchased 10,000 shares
from us at a cash price of $5.50 per share.

                        DESCRIPTION OF OUR CAPITAL STOCK

   Our authorized capital stock consists of 20,000,000 shares of common stock,
no par value, and 10,000,000 shares of preferred stock, no par value.

Common Stock

   The holders of common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the shareholders. Subject to
preferences that may be applicable to any then outstanding preferred stock,
holders of common stock are entitled to receive ratably such dividends as may
be declared by the Board of Directors out of funds legally available therefor.
In the event of a liquidation, dissolution or winding up of Carbon, holders of
the common stock are entitled to share ratably in all assets remaining after
payment of liabilities and the liquidation preference of any then outstanding
preferred stock. Holders of common stock have no preemptive rights and no right
to convert their common stock into any other securities. There are no
redemption or sinking fund provisions applicable to the common stock. All
outstanding shares of common stock are, and all shares of common stock to be
outstanding upon completion of the exchange offer will be, fully paid and
nonassessable.

   A quorum for purposes of a meeting of shareholders consists of a majority of
the shares entitled to vote at the meeting. After a quorum has been
established, a matter is approved by the shareholders if votes cast favoring
the matter exceed the votes cast against the matter. Directors are elected by a
plurality vote, with the nominees having the highest number of votes cast in
favor of their election being elected to the Board of Directors. As a result, a
majority of the outstanding shares has the ability to elect all of our
directors.

   Under Colorado law, the affirmative vote of a majority of the shares
entitled to vote is required to approve:

  .  A sale, lease, exchange or other disposition of all or substantially all
     of our property and assets, with or without our good will, other than in
     the usual and regular course of our business.

  .  A plan of merger of Carbon with or into another entity, or a share
     exchange for which shareholder approval is required.

  .  Dissolution of Carbon.

   At November 1, 1999, there were 4,560,000 shares of our common stock
outstanding.

Preferred Stock

   The Board of Directors has the authority, without further vote or action by
the shareholders, to issue up to 10,000,000 shares of preferred stock in one or
more series and to fix the rights, preferences, privileges and restrictions
thereof, including dividend rights, conversion rights, voting rights, terms of
redemption, liquidation preferences, sinking fund terms and the number of
shares constituting any series or the designation of such series. The issuance
of preferred stock could adversely affect the voting power of holders of common
stock and the likelihood that such holders will receive dividend payments and
payments upon liquidation and could have the effect of delaying, deferring or
preventing a change in control of Carbon. There are no shares of preferred
stock issued, and we have no present plans to issue any shares of preferred
stock.

Certain Effects Of Authorized But Unissued Stock

   Under our Articles of Incorporation and, upon completion of the exchange
offer and assuming 100% acceptance of the exchange offer, there will be
approximately 13,978,600 shares of common stock and

                                       77


approximately 10,000,000 shares of preferred stock available for future
issuance without stockholder approval (except that as part of the criteria for
maintaining a listing on the Amex, we are required to obtain stockholder
approval of certain issuances of stock). These additional shares may be
utilized for a variety of corporate purposes including future public offerings
to raise additional capital or to facilitate corporate acquisitions.

   One of the effects of the existence of unissued and unreserved common stock
and preferred stock may be to enable the Board of Directors to issue shares to
persons friendly to current management which could render more difficult or
discourage an attempt to obtain control of Carbon by means of a merger, tender
offer, proxy contest or otherwise, and thereby protect the continuity of our
management. Such additional shares also could be used to dilute the stock
ownership of persons seeking to obtain control of Carbon.

   The Board of Directors is authorized without any further action by the
shareholders to determine the rights, preferences, privileges and restrictions
of the unissued Preferred Stock. The purpose of authorizing the Board of
Directors to determine such rights and preferences is to eliminate delays
associated with a stockholder vote on specific issuances. The Board of
Directors may issue preferred stock with voting and conversion rights which
could adversely affect the voting power of the holders of common stock, and
which could, among other things, have the effect of delaying, deferring or
preventing a change in control of Carbon.

   We do not currently have any plans to issue additional shares of common
stock or preferred stock other than shares of common stock which may be issued
upon the exercise of options which have been granted or which may be granted
in the future to our employees.

American Stock Exchange Listing

   Our common stock has been approved for quotation on the AMEX under the
symbol           .

Transfer Agent

   We have appointed Harris Trust and Savings Bank, Chicago, Illinois, as the
transfer agent and registrar for our common stock.

                      COMPARISON OF SHAREHOLDERS' RIGHTS

   Shareholders of CEC who tender their shares in the exchange offer will
become shareholders of Carbon. CEC is a corporation organized under and
governed by Alberta, Canada law. Carbon is a corporation organized under and
governed by Colorado law. The principal attributes of Carbon common stock and
CEC common stock are comparable, but there are material differences in
shareholder rights. The following is a summary of these material differences
which arise from the differences between the Colorado Business Corporation
Act, the "CBCA," and the Alberta Business Corporations Act, the "ABCA," and
between the Articles of Incorporation and Bylaws of Carbon and the Articles of
Association and Bylaws of CEC.

   This summary is qualified in its entirety by the terms of the Articles of
Association and Bylaws of CEC and the Articles of Incorporation and Bylaws of
Carbon.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Carbon Energy Corporation:

     We have audited the accompanying balance sheet of CARBON ENERGY
CORPORATION (a Colorado corporation) as of October 20, 1999, and the related
statements of stockholder's equity and cash flow for the period from inception
(September 14, 1999) to October 20, 1999. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audit.

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

     In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Carbon Energy
Corporation as of October 20, 1999, and its cash flow for the period from
inception (September 14, 1999) to October 20, 1999, in conformity with
generally accepted accounting principles.

These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements
based on our audits.

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

                 BONNEVILLE FUELS CORPORATION AND SUBSIDIARIES
         (A Wholly-Owned Subsidiary of Bonneville Pacific Corporation)

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Nature of Operations and Significant Accounting Policies:

   Nature of Operation--Bonneville Fuels Corporation (BFC), a wholly-owned
subsidiary of Bonneville Pacific Corporation (BPC), was incorporated in the
State of Colorado in April 1987 and began doing business in June 1987. The
Company owns four subsidiaries, Bonneville Fuels Marketing Corporation (BFMC),
Bonneville Fuels Management Corporation (BFM Corp.), Bonneville Fuels
Operating Corporation (BFO), and Colorado Gathering Corporation (CGC).
Collectively, these entities are referred to as the Company. The Company's
principal operations include exploration for and production of oil and gas
reserves, marketing of natural gas, and gathering of natural gas. The Company
from time to time also purchases and resells electricity.

   Principles of Consolidation--The consolidated financial statements include
the accounts of BFC and its four wholly-owned subsidiaries. All significant
intercompany transactions and balances have been eliminated in the
accompanying consolidated financial statements.

   Cash Equivalents--The Company considers all highly liquid debt instruments
purchased with an original maturity of three months or less to be cash
equivalents.

   Gas Marketing--The Company's marketing contracts are generally month-to-
month or up to eighteen months, and provide that the Company will sell gas to
end users which is produced from the Company's properties and acquired from
third parties.

   Investment Margin Account--This account generally represents net cash
margin deposits held by a brokerage firm for the Company's trading accounts.

   Oil and Gas Producing Activities--The Company follows the "successful
efforts" method of accounting for its oil and gas properties, all of which are
located in the continental United States. Under this method of accounting, all
property acquisition costs and costs of exploratory and development wells are
capitalized when incurred, pending determination of whether the well has found
proved reserves. If an exploratory well has not found proved reserves, the
costs of drilling the well are charged to expense. The costs of development
wells are capitalized whether productive or nonproductive.

   Geological and geophysical costs and the costs of carrying and retaining
undeveloped properties are expensed as incurred. Depreciation and depletion of
capitalized costs for producing oil and gas properties is computed using the
units-of-production method based upon proved reserves for each field.

   In 1997, the Company began to accrue for future plugging, abandonment, and
remediation using the negative salvage value method whereby costs are expensed
through additional depletion expense over the remaining economic lives of the
wells. Management's estimate of the total future costs to plug, abandon, and
remediate the Company's share of all existing wells, including those currently
shut in is approximately $3,500,000, net of salvage values. The total amount
expensed for this liability was $206,000 and $200,000, for the years ended
December 31, 1998 and 1997, respectively.

   The Company follows Statement of Financial Accounting Standards (SFAS) No.
121, Accounting for Impairment of Long-Lived Assets. This statement limits net
capitalized costs of proved and unproved oil and gas properties to the
aggregate undiscounted future net revenues related to each field. If the net
capitalized costs exceed the limitation, impairment is provided to reduce the
carrying value of the properties in the field to estimated actual value. The
impairment is included as a reduction of gross oil and gas properties in the
accompanying balance sheets. In 1998, 1997, and 1996, the Company recorded
impairments of $1,858,000, $312,000, and $-0-, respectively. Factors causing
the impairment of oil and gas properties in 1998 were the

                                     F-12

         (A Wholly-Owned Subsidiary of Bonneville Pacific Corporation)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
decline in oil prices worldwide and the re-estimation of reserve values on
certain producing properties. The primary factor causing the impairments in
1997 was the reevaluation of certain undeveloped leases.

   Gains and losses are generally recognized upon the sale of interests in
proved oil and gas properties based on the portion of the property sold. For
sales of partial interests in unproved properties, the Company treats the
proceeds as a recovery of costs with no gain recognized until all costs have
been recovered.

   Energy Marketing Arrangements--In 1998, BFC entered into an agreement to
manage certain natural gas contracts of an unrelated entity. For some
contracts, BFC takes title to the gas purchased to service these contracts
prior to the sale under the contracts. For these contracts, BFC consolidates
all revenue, expenses, receivables and payables associated with the contracts.
In contracts where title is not taken, BFC only records the margin associated
with the transaction.

   Other Property and Equipment--Depreciation of other property and equipment
is calculated using the straight-line method over the estimated useful lives
(ranging from 3 to 25 years) of the respective assets. The cost of normal
maintenance and repairs is charged to operating expenses as incurred. Material
expenditures which increase the life of an asset are capitalized and
depreciated over the estimated remaining useful life of the asset. The cost of
properties sold, or otherwise disposed of, and the related accumulated
depreciation or amortization are removed from the accounts, and any gains or
losses are reflected in current operations.

   Deferred Loan Costs--Costs associated with the Company's note payable have
been deferred and are being amortized using the effective interest method over
the original term of the note.

   Gas Balancing--The Company uses the sales method of accounting for amounts
received from natural gas sales resulting from production credited to the
Company in excess of its revenue interest share. Under this method, all
proceeds from production credited to the Company are recorded as revenue until
such time as the Company has produced its share of related estimated remaining
reserves. Thereafter, additional amounts received are recorded as a liability.

   Income Taxes--The Company accounts for income taxes under the liability
method which requires recognition of deferred tax assets and liabilities for
the expected future tax consequences of events that have been included in the
financial statements or tax returns. Under this method, deferred tax assets
and liabilities are determined based on the difference between the financial
statement and tax bases of assets and liabilities using enacted tax rates in
effect for the year in which the differences are expected to reverse. BPC
includes the Company's operations in its consolidated tax return. Income taxes
are allocated by BPC as if the Company were a separate taxpayer.

   Accounting for Hedged Transactions--The Company periodically enters into
futures, forwards, and swap contracts as hedges of commodity prices associated
with the production of oil and gas and with the purchase and sale of natural
gas in order to mitigate the risk of market price fluctuations. Changes in the
market value of futures, forwards, and swap contracts are not recognized until
the related production occurs or until the related gas purchase or sale takes
place. Realized losses from any positions which were closed early are deferred
and recorded as an asset or liability in the accompanying balance sheet, until
the related production, purchase or sale takes place. Gains and losses
incurred on these contracts are included in oil and gas revenue or in gas
marketing costs in the accompanying statements of operations.

   Accounting Estimates--The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in these financial
statements and the accompanying notes. The actual results could differ from
those estimates.

   Reclassifications--Certain reclassifications have been made to conform the
1997 and 1996 financial statements to the presentation in 1998. These
reclassifications had no effect on net income.

Parent Company Bankruptcy and Related Transactions:

   In 1991, BPC filed a petition for re-organization under Chapter 11 of the
U.S. Bankruptcy Code and in June 1992, a Trustee was appointed for the case.
As a result of BPC's bankruptcy, the Company established, prior to 1994, an
allowance for doubtful accounts from BPC equal to the receivable. In 1995,
claims filed against the estate of BPC were amended to total $1,788,000 to
reflect additional amounts due related to pre-petition transactions.

   As a condition of granting a loan in 1991, the lender required that BPC
convert intercompany debt of $3,600,000 to equity. In Board meetings at both
the Company and BPC, the officers of each company were authorized and directed
to complete this financing. In their respective internal financial statements,
both the Company and BPC treated the intercompany debt as converted to equity.
In 1993, it was discovered that the BPC Board resolution to ratify the
conversion had not been duly executed. The Company, therefore, continued to
disclose the intercompany debt as a liability.

   On December 20, 1996, the Bankruptcy Court authorized the Trustee to offset
the mutual debts of the Company and BPC. After the offset, the Company was to
convert any remaining intercompany debt to equity. The Company had
established, prior to 1994, an allowance for doubtful accounts from BPC equal
to the receivable. The amount of the offset equal to the allowance was
recorded as an extraordinary gain on extinguishment of debt, with the
remainder being recorded as a contribution of capital.

   In 1998, BPC approved the conversion of $1,663,000 in taxes payable to
equity. Also in 1998, BPC emerged from bankruptcy.

Long-Term Debt:

   The Company has an asset-based line-of-credit with a bank which provides
for borrowing up to the borrowing base (as defined). The borrowing base was
$13,200,000 at December 31, 1998. At December 31, 1998, outstanding borrowings
amounted to $5,150,000, with interest at a variable rate that approximated 7%
at December 31, 1998. The Company has issued letters of credit totaling
$3,100,000 which further reduces the amount available for borrowing under the
base. This facility is collateralized by certain oil and gas properties of the
Company and is scheduled to convert to a term note on July 1, 2001. This term
loan is scheduled to have a maturity of either the economic half life of the
Company's remaining reserves on the date of conversion, or July 1, 2006,
whichever is earlier. The borrowing base is based upon the lender's evaluation
of BFC's proved oil and gas reserves, generally determined semi-annually. The
future minimum principal payments under the term note will be dependent upon
the bank's evaluation of the Company's reserves at that time.

   The Company also has an accounts receivable-based credit facility which
includes a revolving line-of-credit with the bank which provides for
borrowings up to $1,500,000. Outstanding borrowings under this facility at
December 31, 1998 amounted to $700,000. This facility bears interest at prime
(7.75% at December 31, 1998). This facility is collateralized by certain trade
receivables of BFC and has a maturity date of July 1, 1999.

   The credit agreement contains various covenants which prohibit or limit the
subsidiary's ability to pay dividends, purchase treasury shares, incur
indebtedness, repay debt to the Parent, sell properties or merge with another
entity. Additionally, the Company is required to maintain certain financial
ratios.

Commitments:

   Office Lease--The Company leases office space under a noncancellable
operating lease. Total rental expense was approximately $139,000, $58,000, and
$58,000 for the years ended December 31, 1998, 1997, and 1996, respectively.
Beginning in 1998, the Company has a new lease agreement which provides for
total minimum rental commitments of:

Income Taxes:

   The components of the net deferred tax assets are as follows:



                                                        As of December 31,

      Excess of tax basis over book basis of oil and
       gas properties...............................  $ 1,873,000  $ 1,439,000
                                                      -----------  -----------
      Deferred tax assets...........................    1,873,000    1,439,000
      Less valuation allowance......................   (1,873,000)  (1,389,000)
                                                      -----------  -----------
      Net deferred tax assets.......................  $       --   $    50,000
                                                      ===========  ===========


   The effective tax rate of the Company differed from the Federal statutory
rate primarily due to changes in the valuation allowance on the deferred tax
assets.

Concentrations of Credit Risk and Price Risk Management:

   Concentrations of Credit Risk--Substantially all of the Company's accounts
receivable at December 31, 1998 result from crude oil and natural gas sales
and/or joint interest billings to companies in the oil and gas industry. This
concentration of customers and joint interest owners may impact the Company's
overall credit risk, either positively or negatively, since these entities may
be similarly affected by changes in economic or other conditions. In
determining whether or not to require collateral from a customer or joint
interest owner, the Company analyzes the entity's net worth, cash flows,
earnings, and credit ratings. Receivables are generally not collateralized.
Historical credit losses incurred on trade receivables by the Company have
been insignificant.

   The Company's revenues are predominantly derived from the sale of natural
gas and management estimates that over 85% of the value of the Company's
properties is derived from natural gas reserves.

   Energy Financial Instruments--BFC uses energy financial instruments and
long-term user contracts to minimize its risk of price changes in the spot and
fixed price natural gas and crude oil markets. Energy risk management products
used include commodity futures and options contracts, fixed-price swaps, and
basis swaps. Pursuant to company guidelines BFC is to engage in these
activities only as a hedging mechanism against price volatility associated
with pre-existing or anticipated gas or crude oil sales in order to protect
profit margins. As of December 31, 1998, BFC has financial and physical
contracts which hedge 6 bcf (billion cubic feet) of production through
December 2001.

         (A Wholly-Owned Subsidiary of Bonneville Pacific Corporation)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

   The difference between the current market value of the hedging contracts
and the original market value of the hedging contracts was a favorable
$701,000 and an unfavorable $60,000 as of December 31, 1998 and 1997,
respectively. These amounts are not reflected in the accompanying financial
statements. In the event energy financial instruments do not qualify for hedge
accounting, the difference between the current market value and the original
contract value would be currently recognized in the statement of operations.
In the event that the energy financial instruments are terminated prior to the
delivery of the item being hedged, the gains and losses at the time of the
termination are deferred until the period of physical delivery. Such deferrals
were immaterial in all periods presented.

Financial Instruments:

   SFAS Nos. 107 and 127 requires certain entities to disclose the fair value
of certain financial instruments in their financial statements. Accordingly,
management's best estimate is that the carrying amount of cash, receivables,
notes payable, accounts payable, undistributed revenue, and accrued expenses
approximates fair value of these instruments. See Note 6 for a discussion
regarding the fair value of energy financial instruments.

Management Retention Bonuses and Employment Contracts:

   The Company has accrued bonuses as of December 31, 1998 of $164,000 in
accordance with a management retention program approved by the bankruptcy
court. The Company has also entered into certain employment contracts with key
employees that provide for certain benefits to the employees upon termination
without cause.

Subsequent Event:

   Subsequent to year-end, BPC engaged a financial advisor to pursue various
strategic opportunities. BPC is considering all options including the
continued operation of all its subsidiaries or the sale of the entire company
or any part thereof. No adjustment to the financial statements has been made
to reflect this uncertainty.

         (A Wholly-Owned Subsidiary of Bonneville Pacific Corporation)

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of Operations and Significant Accounting Policies:

   Nature of Operation--Bonneville Fuels Corporation (BFC), a wholly-owned
subsidiary of Bonneville Pacific Corporation (BPC), was incorporated in the
State of Colorado in April 1987 and began doing business in June 1987. BFC
owns four subsidiaries, Bonneville Fuels Marketing Corporation (BFMC),
Bonneville Fuels Management Corporation (BFM Corp.), Bonneville Fuels
Operating Corporation (BFO), and Colorado Gathering Corporation (CGC).
Collectively, these entities are referred to as the Company. The Company's
principal operations include exploration for and production of oil and gas
reserves, marketing of natural gas, and gathering of natural gas. From time to
time the Company also purchases and resells electricity.

   These financial statements are prepared in accordance with generally
accepted accounting principles 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 positions of BFC as of June 30, 1999 and 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 the results
to be expected for the full year.

   Principles of Consolidation--The consolidated financial statements include
the accounts of BFC and its four wholly-owned subsidiaries. All significant
intercompany transactions and balances have been eliminated in the
accompanying consolidated financial statements.

   Cash Equivalents--The Company considers all highly liquid debt instruments
purchased with an original maturity of three months or less to be cash
equivalents.

   Gas Marketing--The Company's marketing contracts are generally month-to-
month or up to eighteen months, and provide that the Company will sell gas to
end users which is produced from the Company's properties and acquired from
third parties.

   Investment Margin Account--This account generally represents net cash
margin deposits held by a brokerage firm for the Company's trading accounts.

   Oil and Gas Producing Activities--The Company follows the "successful
efforts" method of accounting for its oil and gas properties, all of which are
located in the continental United States. Under this method of accounting, all
property acquisition costs and costs of exploratory and development wells are
capitalized when incurred, pending determination of whether the well has found
proved reserves. If an exploratory well has not found proved reserves, the
costs of drilling the well are charged to expense. The costs of development
wells are capitalized whether productive or nonproductive.

   Geological and geophysical costs and the costs of carrying and retaining
undeveloped properties are expensed as incurred. Depreciation and depletion of
capitalized costs for producing oil and gas properties is computed using the
units-of-production method based upon proved reserves for each field.

   In 1997, the Company began to accrue for future plugging, abandonment, and
remediation using the negative salvage value method whereby costs are expensed
through additional depletion expense over the remaining economic lives of the
wells. Management's estimate of the total future costs to plug, abandon, and
remediate the Company's share of all existing wells, including those currently
shut in, is approximately $3,500,000, net of salvage values. The total amount
expensed for this liability was $100,000 and $-0-, for the periods ended June
30, 1999 and 1998, respectively.

                 BONNEVILLE FUELS CORPORATION AND SUBSIDIARIES
         (A Wholly-Owned Subsidiary of Bonneville Pacific Corporation)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

   The Company follows Statement of Financial Accounting Standards (SFAS) No.
121, Accounting for Impairment of Long-Lived Assets. This statement limits net
capitalized costs of proved and unproved oil and gas properties to the
aggregate undiscounted future net revenues related to each field. If the net
capitalized costs exceed the limitation, impairment is provided to reduce the
carrying value of the properties in the field to estimated actual value. The
impairment is included as a reduction of gross oil and gas properties in the
accompanying balance sheets. In the first six months of 1999, the Company
incurred impairment cost of $60,000. In 1998, the Company recorded impairment
cost of $1,858,000. Factors causing the impairment of oil and gas properties
were the decline in oil prices worldwide and the re-assessment of reserve
values on certain producing properties in 1998, and re-assessment of reserve
values on a drilling venture in 1999.

   Gains and losses are generally recognized upon the sale of interests in
proved oil and gas properties based on the portion of the property sold. For
sales of partial interests in unproved properties, the Company treats the
proceeds as a recovery of costs with no gain recognized until all costs have
been recovered.

   Energy Marketing Arrangements--In 1998, BFC entered into an agreement to
manage certain natural gas contracts of an unrelated entity. For contracts
under which BFC takes title to the gas which services these contracts, BFC
consolidates by item, all revenue, expense, receivables and payables associated
with the contracts. In contracts where title is not taken, BFC records only the
margin associated with the transaction. This agreement was terminated at the
end of April 1999.

   Other Property and Equipment--Depreciation of other property and equipment
is calculated using the straight-line method over the estimated useful lives
(ranging from 3 to 25 years) of the respective assets. The cost of normal
maintenance and repairs is charged to operating expenses as incurred. Material
expenditures which increase the life of an asset are capitalized and
depreciated over the estimated remaining useful life of the asset. The cost of
properties sold, or otherwise disposed of, and the related accumulated
depreciation or amortization is removed from the accounts, and any gains or
losses are reflected in current operations.

   Deferred Loan Costs--Costs associated with the Company's note payable have
been deferred and are being amortized using the effective interest method over
the original term of the note.

   Gas Balancing--The Company uses the sales method of accounting for amounts
received from natural gas sales resulting from production credited to the
Company in excess of its revenue interest share. Under this method, all
proceeds from production credited to the Company are recorded as revenue until
such time as the Company has produced its share of related estimated remaining
reserves. Thereafter, additional amounts received are recorded as a liability.

   Income Taxes--The Company accounts for income taxes under the liability
method which requires recognition of deferred tax assets and liabilities for
the expected future tax consequences of events that have been included in the
financial statements or tax returns.

   Under this method, deferred tax assets and liabilities are determined based
on the difference between the financial statement and tax bases of assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse. BPC includes the Company's operations in
its consolidated tax return. Income taxes are allocated by BPC as if the
Company were a separate taxpayer.

   Accounting for Hedged Transactions--The Company periodically enters into
futures, forwards, and swap contracts as hedges of commodity prices associated
with the production of oil and gas and with the purchase and sale of natural
gas in order to mitigate the risk of market price fluctuations. Changes in the
market value of futures, forwards, and swap contracts are not recognized until
the related production occurs or until the related

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
gas purchase or sale takes place. Realized losses from any positions which were
closed early are deferred and recorded as an asset or liability in the
accompanying balance sheet, until the related production, purchase or sale
takes place. Gains and losses incurred on these contracts are included in oil
and gas revenue or in gas marketing costs in the accompanying statements of
operations.

   Reclassifications--Certain reclassifications have been made to conform the
1999 financial statements to the presentation in 1998. These reclassifications
had no effect on net income.

2. Parent Company Bankruptcy and Related Transactions:

   In 1991, BPC filed a petition for re-organization under Chapter 11 of the
U.S. Bankruptcy Code and in June 1992, a Trustee was appointed for the case. As
a result of BPC's bankruptcy, the Company established, prior to 1994, an
allowance for doubtful accounts from BPC equal to the receivable. In 1995,
claims filed against the estate of BPC were amended to total $1,788,000 to
reflect additional amounts due related to pre-petition transactions.

   As a condition of granting a loan in 1991, the lender required that BPC
convert intercompany debt of $3,600,000 to equity. In Board meetings at both
the Company and BPC, the officers of each company were authorized and directed
to complete this financing. In their respective internal financial statements,
both the Company and BPC treated the intercompany debt as converted to equity.
In 1993, it was discovered that the BPC Board resolution to ratify the
conversion had not been duly executed. The Company, therefore, continued to
disclose the intercompany debt as a liability.

   On December 20, 1996, the Bankruptcy Court authorized the Trustee to offset
the mutual debts of the Company and BPC. After the offset, the Company was to
convert any remaining intercompany debt to equity. The Company had established,
prior to 1994, an allowance for doubtful accounts from BPC equal to the
receivable. The amount of the offset equal to the allowance was recorded as an
extraordinary gain on extinguishment of debt, with the remainder being recorded
as a contribution of capital.

   In 1998, BPC approved the conversion of $1,663,000 in taxes payable to
equity. Also in 1998, BPC emerged from bankruptcy.

3. Long-Term Debt:

   The Company has an asset-based line-of-credit with a bank which provides for
borrowing up to the borrowing base (as defined). The borrowing base was
$16,900,000 at June 30, 1999. Outstanding borrowings amounted to $8,400,000,
with interest at a variable rate that approximated 6.70% at June 30, 1999. The
Company has issued letters of credit totaling $2,500,000 which further reduce
the amount available for borrowing under the base. This facility is
collateralized by certain oil and gas properties of the Company and is
scheduled to convert to a term note on July 1, 2001. This term loan is
scheduled to have a maturity of either the economic half life of the Company's
remaining reserves on the date of conversion, or July 1, 2006, whichever is
earlier. The borrowing base is based upon the lender's evaluation of BFC's
proved oil and gas reserves, generally determined semi-annually. The future
minimum principal payments under the term note will be dependent upon the
bank's evaluation of the Company's reserves at that time.

   The Company also has an accounts receivable-based credit facility which
includes a revolving line-of-credit with the bank which provides for borrowings
up to $1,500,000. Outstanding borrowings under this facility at June 30, 1999
amounted to $300,000. This facility bears interest at prime (7.75% at June 30,
1999). This facility is collateralized by certain trade receivables of BFC and
has a maturity date of July 1, 2001.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
   The credit agreement contains various covenants which prohibit or limit the
Company's ability to pay dividends, purchase treasury shares, incur
indebtedness, repay debt to the Parent, sell properties or merge with another
entity. Additionally, the Company is required to maintain certain financial
ratios.

4. Commitments:

   Office Lease--The Company leases office space under a noncancellable
operating lease. Total rental expense was approximately $73,000 and $57,000 for
the periods ended June 30, 1999 and 1998, respectively. Beginning in 1998, the
Company has a new lease agreement which provides for total minimum rental
commitments of:

   The components of the net deferred tax asset are as follows:

                                                                  -----------

   The Company has not accrued an income tax liability for the six months
ending June 30, 1999 due to the availability of intangible drilling cost which
will essentially eliminate taxable net income.

   The effective tax rate of the Company differed from the Federal statutory
rate primarily due to changes in the valuation allowance on the deferred tax
asset.

6. Concentrations of Credit Risk and Price Risk Management:

   Concentrations of Credit Risk--Substantially all of the Company's accounts
receivable at June 30, 1999 result from crude oil and natural gas sales and/or
joint interest billings to companies in the oil and gas industry. This
concentration of customers and joint interest owners may impact the Company's
overall credit risk, either positively or negatively, since these entities may
be similarly affected by changes in economic or other conditions. In
determining whether or not to require collateral from a customer or joint
interest owner, the Company analyzes the entity's net worth, cash flows,
earnings, and credit ratings. Receivables are generally not collateralized.
Historical credit losses incurred on trade receivables by the Company have been
insignificant.

   The Company's revenues are predominantly derived from the sale of natural
gas. Management estimates that over 85% of the value of the Company's
properties is derived from natural gas reserves.

   Energy Financial Instruments--BFC uses energy financial instruments and
long-term user contracts to minimize its risk of price changes in the spot and
fixed price natural gas and crude oil markets. Energy risk management products
used include commodity futures and options contracts, fixed-price swaps, and
basis swaps. Pursuant to company guidelines BFC is to engage in these
activities only as a hedging mechanism against price volatility associated with
pre-existing or anticipated gas or crude oil sales in order to protect profit
margins. As of June 30, 1999, BFC has financial and physical contracts which
hedge 5.1 bcf (billion cubic feet) of production through December 2001.

         (A Wholly-Owned Subsidiary of Bonneville Pacific Corporation)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

   The difference between the current market value of the hedging contracts
and the original market value of the hedging contracts was an unfavorable
$894,000 and an unfavorable $209,000 as of June 30, 1999 and 1998,
respectively. These amounts are not reflected in the accompanying financial
statements. In the event energy financial instruments do not qualify for hedge
accounting, the difference between the current market value and the original
contract value would be currently recognized in the statement of operations.
In the event that the energy financial instruments are terminated prior to the
delivery of the item being hedged, the gains and losses at the time of the
termination are deferred until the period of physical delivery. Such deferrals
were immaterial in all periods presented.

7. Financial Instruments:

   SFAS Nos. 107 and 127 requires certain entities to disclose the fair value
of certain financial instruments in their financial statements. Accordingly,
management's best estimate is that the carrying amount of cash, receivables,
notes payable, accounts payable, undistributed revenue, and accrued expenses
approximates fair value of these instruments. See Note 6 for a discussion
regarding the fair value of energy financial instruments.

8. Management Retention Bonuses and Employment Contracts:

   The Company has accrued bonuses as of June 30, 1999 of $164,000 in
accordance with a management retention program approved by the bankruptcy
court. The Company has also entered into certain employment contracts with key
employees that provide for certain benefits to the employees upon termination
without cause.

9. Subsequent Event:

   During the first quarter, BPC engaged a financial advisor to pursue various
strategic opportunities. BPC is considering several options including the
continued operation of all its subsidiaries or the sale of the entire company
or any part thereof. BFC management has had discussions with various
interested parties during the second quarter, but no agreements have been
reached. No adjustment to the financial statements has been made to reflect
this uncertainty.

                              CEC RESOURCES LTD.

                       NOTES TO THE FINANCIAL STATEMENTS

(1) Formation and Operations of the Company

   CEC Resources Ltd. ("Resources" or "the Company") was incorporated as an
Alberta, Canada corporation on May 31, 1955 and, since its acquisition in 1969
as a wholly-owned Canadian subsidiary by its former parent, Consolidated Oil &
Gas, Inc., has been engaged in exploration, development and production of oil
and gas reserves in Canada and oil and gas field services. Resources was a
wholly-owned subsidiary of Columbus Energy Corp. ("Parent" or "Columbus") from
1984 until February 24, 1995 when 100% of the Resources shares were sold by
its Parent to its shareholders or the public in a rights offering.

(2) Accounting Policies

   The financial statements of the Company are prepared in accordance with
Canadian generally accepted accounting principles ("GAAP") and require the use
of management's estimates. The following is a summary of the significant
accounting policies followed by the Company.

 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 flows, 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 flows.

 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 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 to one barrel of oil. Depreciation
of the liquid extraction plant and other assets 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 expense 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.

                              CEC RESOURCES LTD.

                NOTES TO THE FINANCIAL STATEMENTS--(Continued)


 Income Taxes

   The liability method is used in measuring income taxes based on temporary
differences including both timing differences and other differences between
the tax basis of an asset or liability and its carrying amount in the
financial statements. This method uses the tax rate and 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.

 Field Services

   The Company recognizes revenue for field services provided to third parties
from its one-third ownership in the Carbon area liquids extraction plant as
well as from facilities in other fields.

   The Company's share of the cost of providing such third party services is
expensed and shown as "field services" cost.

 Earnings Per Share

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

(3) Reclassification

   Effective for the 1998 fiscal year, Resources has classified its
stockholders' equity to conform to Canadian laws in Alberta to combine stated
capital and additional paid-in capital as share capital as well as to net the
purchase of shares against those accounts when they are cancelled.
Accordingly, year end stockholder equity balances for 1995 through 1997 have
been reclassified as follows:

(4) Statements of Cash Flows

   The Company elected to adopt Canadian Institute of Chartered Accountants
(CICA) 1540, Cash Flow Statements for fiscal 1998. This statement requires a
business enterprise to provide a statement of cash flows in place of a
statement of changes in financial position. Application of this statement is
required for fiscal years

                NOTES TO THE FINANCIAL STATEMENTS--(Continued)

beginning on or after August 1, 1998, and earlier application is encouraged.
Cash flow information for earlier years that is presented with corresponding
information for the initial year of application is restated to conform to the
requirements of CICA 1540 as follows:

                                       ======                   =======


   There are no restatements for the year ended November 30, 1996. The
adjustments for 1997 were due to capital expense accruals that are excluded in
calculating cash flows from investing activities.

(5) Oil and Gas Producing Activities

   The following tables set forth the capitalized costs related to oil and gas
producing activities, costs incurred in oil and gas property acquisition,
exploration and development activities, and results of operations for

   The Company sells its own natural gas production in the Carbon and East
Carbon areas directly to gas marketing companies. The operator of the gas
processing plant pays Resources for liquids sold at the plant tailgate and
those amounts are included in Customer 2.

   During the fourth quarter of 1998, the Company made a change in accounting
estimate in proved reserves due to a significant decrease in proved developed
non-producing and proved undeveloped reserves. The majority of this decrease
is attributable to the unsuccessful completion of a well in the East Carbon
area and additional offset well information. The effect of this change on
current year operations was an increase in depletion expense of $190,000.

   For Canadian income tax purposes, Resources has the following tax
attributes available at November 30, 1998 to reduce future taxable income
which have been included in calculating the temporary differences above:

  Accumulated property exploration and development costs of $1,696,000,
  earned depletion base of $1,167,000 and undepreciated capital cost of
  $1,152,000. The tax attributes of carryforward pools are included to
  determine the temporary differences shown as deferred tax liabilities.
  These attributes generally do not expire.

(7) Related Party Transactions

   The Company incurs certain direct and indirect general and administrative
costs for management services provided by its former Parent in lieu of
expanding the number of its own full-time employees. These costs are primarily
for labor, related benefits and other overhead costs. The following table sets
forth these costs, in thousands, for each period:

(8) Capital Stock

   During November 1996, the Company issued 79,000 shares of common stock at
U.S. $5.25 per share by private placement using an investment letter under a
Regulation D exemption of which 38,000 shares were purchased by Resources'
then President and Chairman of the Board.

   During June 1998, McDonald Energy, LLC ("McDonald"), a Colorado limited
liability company solely owned by Patrick R. McDonald, currently a director,
President and Chief Executive Officer of Resources acquired 70,000 shares of
common stock by direct purchase from Resources for U.S. $5.50 per share.

   On October 27, 1994 the Company's Board of Directors authorized an
unlimited number of shares of preferred stock, no par value, none of which is
currently issued.

   On October 27, 1994 the Company adopted an Employee Incentive Share Option
Plan (the "Plan"). The Plan is administered by a committee appointed by the
Board of Directors of the Company. The Plan authorizes the committee to grant
options for up to 300,000 shares of the Company's common stock. The shares are
to be issued out of the Company's authorized and unissued shares and will be
issued as fully paid and non-assessable. Also, the number of Resources shares
so reserved for issuance or subject to an option under the Plan to any one
person may not exceed 5% of the number of Resources shares which are
outstanding at the time of the granting of the option.

                NOTES TO THE FINANCIAL STATEMENTS--(Continued)


   Options may be granted to officers, directors and regular full and part-
time employees of the Company and majority-owned subsidiaries. Options may be
exercised starting one year after grant. The option term cannot be less than
one year or more than five years from the date the option is granted. The
option price may not be less than 100% of the fair market value of the last
trading price on the date the option is granted.

   During 1996, the Board of Directors granted stock options for 30,000 shares
at the exercise price of U.S. $5.50 per share and an option for 10,000 shares
was exercised at the price of U.S. $3.25 per share. At November 30, 1996,
there were 80,000 shares under option at prices ranging from U.S. $3.25 to
U.S. $6.00 per share, of which 50,000 shares were exercisable.

   No options were granted in fiscal year 1997. At November 30, 1997, there
were 80,000 shares under option at prices ranging from U.S. $3.25 to U.S.
$6.00 per share, all of which were exercisable.

   During 1998, the Board of Directors granted stock options for 152,000
shares at exercise prices ranging from U.S. $4.625 to U.S. $5.50 per share and
a stock option grant of 10,000 shares at U.S. $6.00 per share expired. At
November 30, 1998 there were 222,000 shares under option at prices ranging
from U.S. $3.25 to U.S. $6.00 per share, of which 70,000 shares are
exercisable.

   On June 30, 1998, Resources entered into a Stock Purchase Agreement (the
"Agreement") with McDonald. In connection with the Agreement, McDonald was
granted a one-year option to purchase 250,000 shares of common stock at U.S.
$6.00 per share, all of which are exercisable and were granted in addition to
options granted to Mr. McDonald as a director and officer.

(9) Financial Instruments

   The nature of the Company's operations exposes the Company to fluctuations
in commodity prices. The Company attempts to manage these risks by minimizing
its commodity price exposure through the use of derivative contracts. Gain and
losses on these contracts are deferred and recognized in income as an
adjustment to oil and gas sales revenues during the period in which the
physical product to which the contracts relate is actually sold.

   During the fourth quarter of 1998, the Company entered into three AECO
C/N.I.T. based forward price hedge transactions. The terms of these
transactions are as follows:

   The unrecognized gain on these contracts totaled $148,000 based on November
30, 1998 market values.

(10) Commitments and Contingent Liabilities

   The Company leases office space in Calgary, Alberta and Denver, Colorado.
These leases are month-to-month with no related future minimum lease payments.
Total rent expense for 1998, 1997 and 1996 was $64,000, $34,000 and $33,000,
respectively.

   The Company adopted a separation pay policy effective February 24, 1995
which covers all regular terminations and, in addition, certain "special"
terminations of officers in the case of certain contractions and restrictions
of the Company, or in the event of a change of control of the Company. At the
discretion of the

                NOTES TO THE FINANCIAL STATEMENTS--(Continued)

Board of Directors, officers and non-officer employees may receive upon their
retirement the same benefits they would have received upon a friendly change
of control of the Company. As of November 30, 1998 no benefits are payable.

   Resources sells its natural gas production in the Carbon and East Carbon
areas directly to certain gas marketing companies. At November 30, 1998 the
Company had entered into three forward price hedge transactions, as described
in Note 9. The majority of the Company's remaining gas is contracted to a gas
marketing company on a deliverability basis and sold at published index prices
less applicable transportation and marketing charges. The Company has assigned
its firm transportation agreements through October 1999 but has reserved the
right to obtain firm transportation service in its own name.

   The Company estimates that future costs of site abandonment and restoration
of well sites, gas processing plant and other facilities will be $310,000 as
of November 30, 1998 in addition to $165,000 already accrued as a liability.
The estimated costs are being recognized on the unit of production basis over
the life of the properties.

(11) Industry Segments

   The Company's business is primarily participating in (1) oil and gas
exploration and development, and (2) field services.

(12) Concentrations of Credit Risk and Financial Instruments

   The carrying amounts of cash and cash equivalents, accounts receivable, and
accounts payable approximate fair value because of the short maturity of these
instruments. Financial instruments, which potentially subject the Company to
concentrations of credit risk, consist principally of cash and cash
equivalents and accounts receivable.

   The Company maintains demand deposit accounts with separate banks in
Calgary, Alberta and Denver, Colorado. The Company also invests cash in the
highest rated commercial paper of large Canadian companies, with maturities
not over 30 days, which have minimal risk of loss. At November 30, 1998 the
Company had $1,598,000 invested in such commercial paper.

   Most jointly owned oil and gas properties are operated by other companies
who sell oil and liquids production to relatively large Canadian oil and gas
purchasers (see Note 5) and who pay vendors of oil and gas services on the
wells. The Company sells its own natural gas production in the Carbon and East
Carbon Areas directly to certain gas marketing companies. The risk of non-
payment by the purchasers or by those operators is monitored and is considered
minimal. The Company does not obtain collateral from these purchasers to
assure payment for sales to them. Joint interest receivables are subject to
collection under the terms of operating agreements which provide lien rights
to the operator.

   In management's judgment, termination by any purchaser under which its
present sales are made would not have a material impact upon its ability to
sell its production to another purchaser at similar prices. Also, because the
Company has a high percentage of natural gas reserves, results of operations
are particularly sensitive to current pricing. The sensitivity to current
prices has been partially mitigated by the Company's use of financial
instruments that provide a fixed sales price for a percentage of the Company's
production.

(13) Generally Accepted Accounting Principles in Canada and the United States

   The financial statements have been prepared in accordance with Canadian
GAAP which differ in certain respects from those principles that the Company
would have followed had its financial statements been prepared in accordance
with U.S. GAAP. Differences in disclosures 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 of temporary
  investments with maturities greater than 90 days in cash. The differences
  in measurement had no impact on classification in the balance sheets.

     (b) Basic earnings per share using U.S. GAAP is the same as basic
  earnings per share using Canadian GAAP. Diluted earnings per share using
  U.S. GAAP uses the "treasury stock method". Fully diluted earnings per
  share using Canadian GAAP assumes cash proceeds from the deemed exercise of
  stock options are invested in such a way as to earn a reasonable return but
  the number of shares remains the same.

     (c) Using the full cost accounting method under U.S. GAAP, the ceiling
  test is applied to capitalized costs using a 10% discount factor. There
  would be no impairment of the U.S. full cost pool under this method.

Stock Based Compensation Plans

   Using U.S. GAAP, the Company would have adopted in 1996, Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS No. 123"). The Company would have elected to continue to
measure compensation costs for these plans using the current method of
accounting under

                                     F-41


                              CEC RESOURCES LTD.

                NOTES TO THE FINANCIAL STATEMENTS--(Continued)

Accounting Principles Board ("APB") Opinion No. 25 and related interpretations
in accounting for its stock option plan. Accordingly, no compensation expense
is recognized for stock options granted with an exercise price equal to the
market value of Resources stock on the date of grant. Had compensation cost
for the Company's stock option plan been determined using the fair-value
method in SFAS No. 123, the Company's net income and earnings per share would
have been as follows:

(14) SUBSEQUENT EVENTS

   In December 1998, the Company acquired working interests in 16 producing
natural gas wells and associated leaseholds in the Wayne-Rosedale Field,
located in Alberta, Canada, effective September 1, 1998 for $2.3 million. The
assets, liabilities, revenues and expenses for the period September through
November 1998 have not been recorded as of November 30, 1998 because the
closing did not take place until after year end.

   In December 1998, the Company secured a financing commitment. The initial
commitment is a $2.5 million revolving production loan. The revolving phase of
the loan will expire on April 30, 1999 and may be renewed by the bank. The
interest rate on outstanding borrowings is the CIBC Prime Rate plus 3/4 of 1%.

                       NOTES TO THE FINANCIAL STATEMENTS
                                  (Unaudited)

(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 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.

                NOTES TO THE FINANCIAL STATEMENTS--(Continued)
                                  (Unaudited)

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

   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-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 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:

      Apr 00-Oct 00.......................     750      160,500      $2.925


   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
periods presented. The pro forma results are not intended to be a

(7) Long-Term Debt

   The Company has a revolving loan from a bank used to finance acquisitions
of oil and gas reserves and for normal operating requirements. The loan is
secured by the Company's oil and gas assets and had a borrowing base of $5.0
million at August 31, 1999. The interest rate on the outstanding borrowings is
the bank's prime rate, plus 3/4% which has averaged 7.25% for the nine months
ended August 31, 1999. The revolving phase of the loan will expire on April
30, 2000 and may be renewed by the bank. If the revolving commitment is not
renewed by the bank the loan will be converted into a term loan and will be
permanently reduced by way of conseutive monthly principal payments over a
period not to exceed 36 months. Outstanding borrowings amounted to $4.5
million at August 31, 1999.


(8) 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 classification 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 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 20. Indemnification Of Directors And Officers

   Under the Colorado Business Corporation Act, we have broad powers to
indemnify our directors and officers against liabilities they may incur in
such capacities, including liabilities under the Securities Act. Colorado law
provides that a director, officer or any other employee, fiduciary or agent,
may be entitled to indemnification if: (1) the person conducted himself or
herself in good faith; (2) the person reasonably believed, (a) in the case of
conduct in an official capacity with the corporation, that his or her conduct
was in the corporation's best interests, and (b) in all other cases, that his
or her conduct was at least not opposed to the corporation's best interests;
and (3) in the case of any criminal proceeding, the person had no reasonable
cause to believe his or her conduct was unlawful. A corporation may not
indemnify a director in connection with a proceeding by or in the right of the
corporation in which the director was adjudged liable to the corporation or in
connection with any other proceeding charging that the director derived an
improper personal benefit, whether or not involving action in an official
capacity, in which the director was adjudged liable on the basis that he or
she derived an improper personal benefit.

   Our Bylaws provide that we will indemnify our directors and executive
officers and may indemnify our other officers, employees and other agents to
the full extent permitted under Colorado law. We have also entered into
indemnification agreements with each of our executive officers and directors.
The terms of these indemnification agreements are described in "Management--
Indemnification and Limitation of Liability."

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers or persons controlling Carbon
pursuant to the foregoing provisions, we have been informed that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is therefore unenforceable.

Item 22. Undertakings

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

                                     II-2


                                  SIGNATURES
