FORWARD-LOOKING STATEMENTS

     This document includes "forward-looking statements" within the meaning of
various provisions of the Securities Act and the Securities Exchange Act of
1934, as amended. The words "expect," "estimate," "anticipate," "predict,"
"believe," and similar expressions and variations thereof are intended to
identify forward-looking statements. All statements, other than statements of
historical facts, included in this document that address activities, events, or
developments that the Company expects or anticipates will or may occur in the
future, including such things as estimated future net revenues from oil and
natural gas reserves and the present value thereof, drilling of wells, future
production of oil and gas, future capital expenditures (including the amount and
nature thereof), business strategy and measures to implement strategy,
competitive strengths, goals, expansion, and growth of the Company's business
and operations, plans, references to future success, references to intentions as
to future matters and other such matters are forward-looking statements and
include statements regarding the interest, belief or current expectations of the
Company, its directors, or its officers regarding such matters. These statements
are based on certain assumptions and analyses made by the Company in light of
its experience and its perception of historical trends, current conditions and
expected future developments as well as other factors it believes are
appropriate under the circumstances. However, whether actual results and
developments will conform with the Company's expectations and predictions is
subject to a number of risks and uncertainties, including the risk factors
discussed in this document, future oil and gas prices, future operating costs,
severance and excise taxes, actions and approvals of the Bankruptcy Court,
general economic, market or business conditions, the opportunities (or lack
thereof) that may be presented to and pursued by the Company, competitive
actions by other oil and natural gas companies, changes in laws or regulations,
and other factors, many of which are beyond the control of the Company. In
addition, the approval of a plan of reorganization can potentially have a
material impact on the Company and its future operations. Consequently, all of
the forward-looking statements made in this document are qualified by these
cautionary statements and there can be no assurance that the actual results or
developments anticipated by the Company will be realized or, even if
substantially realized, that they will have the expected consequences to or
effects on the Company or its business or operations. Such statements are not
guarantees of future performance and actual results or developments may differ
materially from those projected in the forward-looking statements.

BACKGROUND AND RECENT DEVELOPMENTS

     National Energy Group, Inc. was incorporated under the laws of the State of
Delaware on November 20, 1990. Effective June 11, 1991, Big Piney Oil and Gas
Company and VP Oil, Inc. merged with and into the Company. On August 29, 1996,
Alexander Energy Corporation was merged with and into a wholly-owned subsidiary
of the Company, which subsidiary was merged with and into the Company on
December 31, 1996.

     The Company is an independent energy company which has historically engaged
in the exploration, acquisition, exploitation, development and production of oil
and natural gas properties in major producing basins onshore in Texas,
Louisiana, Oklahoma, Arkansas and offshore in the Gulf of Mexico.

     On December 4, 1998, certain of the holders of the Senior Notes of National
Energy Group, Inc. filed an Involuntary Petition for an Order for Relief under
Chapter 11 of Title 11 of the United States Bankruptcy Code in the United States
Bankruptcy Court for the Northern District of Texas, Dallas Division, due to
non-payment of interest due December 2, 1998, after expiration of a 30-day grace
period. On December 23, 1998, the Company filed, in the Bankruptcy Court, an
Answer to and Motion to Dismiss the pending Involuntary Petition. The Company's
Motion affirmed that it (i) was meeting its obligations and generally paying its
debts as they become due, unless such debts were the basis of a bona fide
dispute and (ii) had arranged with the lender under its credit facility to
borrow additional funds sufficient to pay the interest due on the Senior Notes,
conditioned upon the Court's dismissal of the Involuntary Petition. However, on
February 8, 1999, the Bankruptcy Court denied the Company's Motion to Dismiss
the Involuntary Petition. An Order for Relief was entered by the Bankruptcy
Court on February 11, 1999. The Order for Relief placed the Company under the
protection of the

                                        3
<PAGE>   5

Court and precluded payment of the interest on the Senior Notes until the
conclusion of the Bankruptcy proceeding. Additionally, payment of liabilities
existing as of February 11, 1999 to certain unsecured creditors and dividends in
arrears to holders of the Company's preferred stock and any pending litigation
are stayed during the Bankruptcy proceeding. The Company shall act as
debtor-in-possession and will continue to operate its business and manage its
properties in the ordinary course of business during its Chapter 11 proceeding.
As a result of the Chapter 11 proceeding, the Company discontinued the accrual
of interest on the unsecured Senior Notes and discontinued the accrual of
dividends on the unsecured preferred stock. Approximately $17.7 million
additional interest expense would have been recognized by the Company for 1999
if not for the discontinuation of the interest accrual on the Senior Notes.

     On August 4, 1999, the Company and the unsecured creditors' committee (the
"Committee") appeared before the Bankruptcy Court and announced agreement on the
process for marketing the Company and/or its assets. The Court entered an order
which provided that the Company and the Committee would employ CIBC World
Markets Corp. ("CIBC") to solicit bids for sale of the Company and/or its
assets. The Company assisted CIBC in assembling a data room for potential
bidders to view information regarding the Company's assets. CIBC marketed the
Company's assets pursuant to procedures approved by the Company, the Committee
and the Court. In addition, the Court approved the retention of Netherland,
Sewell & Associates, Inc. to (i) complete its reserve evaluation of the
Company's oil and natural gas properties as of December 31, 1998, (ii) update
the reserve evaluation as of July 1, 1999 and (iii) provide assistance to the
Company, CIBC and prospective buyers during the marketing process. The marketing
process culminated in an auction conducted by the Bankruptcy Court on November
1, 1999. At the auction, bidding on the Company's oil and gas properties,
exclusive of the Company's Lake Mongoulois and Mustang Island properties,
ultimately ended at a high bid of $96.25 million given by Arnos, Corp. ("Arnos")
an affiliated subsidiary of the Company's Series D preferred stockholder. The
Committee, after review, concluded that it would recommend to the Court that it
accept the high bid of $96.25 million. An order accepting Arnos as the highest
bidder was signed by the Court on November 16, 1999. Arnos filed a motion to
close the Purchase and Sale Agreement ("Arnos PSA") into escrow pending (i) the
Court's confirmation of a plan of reorganization or (ii) in the event a plan of
reorganization is not confirmed, a court ordered closing of the sale of the
properties to Arnos. On or about January 28, 2000 the substantive purchase and
sale closing documents were delivered into the registry of the Court, however,
the closing of the Arnos PSA is still pending as noted. The Court approved this
motion and ordered Arnos to pay into the Court's registry the sum of $61.625
million which equals the purchase price of $96.25 million less a previously
escrowed deposit of $9.625 million and the principal balance of $25 million
outstanding under the Company's secured credit facility with Arnos.

     On February 28, 2000, the Committee filed with the Court a Joint Disclosure
Statement ("Committee Disclosure Statement") and proposed Plan of Reorganization
(the "Committee Plan"). The Committee Plan provides for (i) the possibility of a
limited continuation of the Company's oil and gas business operations; (ii) the
creation of a creditors trust to which will be transferred substantially all of
the cash and cash equivalents remaining in the Company, the funds held in the
Registry of the Court from the auction of the Company's properties, and all
causes of action for the payment and primary benefit of certain allowed
administrative, tax, priority and miscellaneous secured and unsecured creditors;
and (iii) payment in full of the secured claims. The Committee Plan designates
eight (8) classes of claims and equity interests. The Company's Senior
Noteholders are deemed to be Allowed Class 6 Claims in the Committee's Plan and
are entitled to their pro rata share of the remaining proceeds in the creditors
trust after payment of the secured claims. Following distribution of the
creditors trust fund to the various claimants, the Committee retains the right
to sell the Company's remaining assets or sell to third parties the rights of
the Senior Noteholders to retain between 49% and 95% of the outstanding stock of
the reorganized Company in the form of newly issued additional common stock. In
connection therewith, the Senior Noteholders shall have the right to elect all
members of the Company's Board of Directors for a two (2) year term following
the effective date of the Committee's Plan. The Committee's Plan further
provides that all of the Company's preferred stock shall be converted into
Common Stock at a conversion price of $.25 per share, and the existing common
and preferred equity interests of the Company shall remain in existence. Neither
the Company's preferred shareholders, nor the Company's common shareholders are
entitled to vote on the Committee's Plan and have been deemed for all purposes
to have rejected it in its entirety. Both

                                        4
<PAGE>   6

the Committee Plan and Committee Disclosure Statement are subject to amendment,
and a hearing in the Bankruptcy Court on the Committee Disclosure Statement is
scheduled on April 17, 2000.

     On March 14, 2000, the Company filed with the Court a Joint Disclosure
Statement ("Company Disclosure Statement") and Plan of Reorganization (the
"Company Plan"). The Company Plan provides for (i) continuation of the Company's
oil and gas business operations; (ii) payment in full of all secured claims,
including the Arnos secured claim in the amount of $25 million, plus interest as
may be due; (iii) payment of a cash sum not to exceed $10,000 to certain classes
of claimants involved in litigation with the Company if such class accepts the
Company's Plan or, alternatively, if rejected by such class, cash in the amount
of 56.5% of any Allowed Claim in such class; (iv) acquisition by Arnos of any
Senior Notes, not otherwise held by Arnos, in consideration of a payment equal
to 56.5% of the face value of each such bond acquired, or, alternatively, a pro
rata share of the cash which Senior Noteholders would receive in a liquidation,
plus a pro rata beneficial interest in a creditor's trust consisting of certain
causes of action, two properties of the Company and $250,000 in cash; (v)
payment of a cash sum equal to 75% of any Allowed Claim to trade creditors; (vi)
retention by each of the preferred and common shareholder equity interests;
provided that both the preferred and common equity interests may, at the option
of Arnos, be deemed cancelled and reissued to holders in a form to be determined
by Arnos; (vii) purchase by Arnos, or an affiliate of Arnos, of additionally
issued shares of the reorganized Company's common stock to the extent that Arnos
or its affiliate shall own up to 49% of all the issued and outstanding common
stock of the reorganized Company; and (viii) amendment to the Senior Notes
Indenture. The Company's Plan further proposes that the Company's existing
officers and directors shall continue as the officers and directors of the
reorganized Company until otherwise replaced as provided in the Company's
bylaws. Neither the Company's preferred shareholders, nor the Company's common
shareholders are entitled to vote on the Company's Plan and have been deemed for
all purposes to have rejected it in its entirety. Both the Company Plan and
Company Disclosure Statement are subject to amendment, and a hearing in the
Bankruptcy Court on the Company Disclosure Statement is scheduled on April 20,
2000.

     Pursuant to an Order of the Bankruptcy Court dated September 7, 1999, the
Company's severance policy was abated and a Court ordered severance program was
put into effect for all employees of the Company ("Severance Program"). The
Severance Program provides for contingent payments as follows: (a) a "stay-pay"
component payable on the earlier of an employees termination without cause; the
closing of a sale of substantially all the Company's assets or the confirmation
of a plan of reorganization; and (b) a "severance" component, whereby upon
termination any employee who does not obtain new employment, or is not offered a
permanent job in Dallas, Texas for a period of at least one year at the same pay
and benefits provided by the Company, shall be entitled to certain severance
benefits. The Order also provided that any employee who participates in the
Severance Program waives and releases any and all claims arising from any
current Employment Agreement with the Company. Certain employees are not
entitled to any payments under the Severance Program until the earlier of (i)
confirmation of a Plan of Reorganization, (ii) conversion to a Chapter 7
bankruptcy proceeding or (iii) termination of their employment by a trustee
appointed by the Court.

     The Company's last annual meeting of shareholders was held on June 4, 1998,
and due to the Company's bankruptcy proceeding, no meeting was held during 1999.
Accordingly, the Company is in violation of its Delaware charter which requires
that an annual meeting of shareholders be held each year or within thirteen
months of the last annual meeting of shareholders. Such failure to hold an
annual meeting of shareholders within the designated period could result in an
order by the Delaware Court of Chancery compelling such a meeting if deemed
appropriate. The Company anticipates that no annual meeting of shareholders will
be convened until such time that the Company's bankruptcy proceeding has
concluded.

     The accompanying consolidated financial statements have been prepared on a
going concern basis of accounting and do not reflect any adjustments that might
result should the Company be unable to continue as a going concern. The
Company's prior losses from operations and the related Chapter 11 proceeding
raise concern about its ability to continue as a going concern. The
appropriateness of using the going concern basis is dependent upon, among other
things, (i) confirmation of a plan of reorganization under the Bankruptcy Code
which provides for continuation of the Company's oil and gas operations, (ii)
the ability to achieve profitable operations after such confirmation and (iii)
the ability to generate sufficient cash from operations to meet its obligations.

     Due to the Chapter 11 filing, the Company has suspended its exploratory and
development drilling program. The Company has been limited in its capital
expenditures to ordinary course enhancement of current production through
workovers, recompletions, and other production enhancing activities deemed to be
economic. During the bankruptcy proceeding, development drilling is anticipated
to be limited to (i) ordinary course non-operated wells in which the Company
owns limited working interests and in which the failure to participate may
result in drainage, depletion or loss of current reserves and (ii) operated
wells deemed to be economical given current oil and gas prices. Large
expenditures for developmental drilling may require court approval and none are
planned at this time.

     At December 31, 1999, the Company had estimated Proved Reserves, as
determined from reserve reports prepared by Netherland, Sewell & Associates,
Inc., of 96.6 Bcfe with a PV10% at that date of approximately $108.9 million.
The reserves were approximately 65.0% natural gas and 88.1% Proved Developed
Reserves.

PRINCIPAL AREAS OF OPERATIONS

     Due to the Chapter 11 filing the Company has suspended its exploratory and
development drilling program. However, the Company currently has an inventory of
exploratory prospects in Louisiana and offshore at Mustang Island.

     Historically, the Company has developed and exploited existing properties
by drilling Development Wells, and recompleting and reworking existing wells.
The Company will continue to participate in non-operated wells as described
above and continue its drilling operations where economical in accordance with
the rulings and procedures set forth by the Court.

     The following table sets forth the Company's principal areas of operations
and the Company's Proved Reserves of oil and natural gas at December 31, 1999.

  MID-CONTINENT AREA

     At December 31, 1999, approximately 37.5% (36.2 Bcfe) of the Company's
Proved Reserves were located in the Mid-Continent area in Oklahoma and Western
Arkansas which includes the Anadarko and Arkoma Basins.

                                        6
<PAGE>   8

     ANADARKO BASIN. The Anadarko Basin is considered a mature oil and natural
gas province characterized by multiple producing horizons and relatively long
reserve lives. Drilling a Producing Well on these locations can convert Proved
Undeveloped Reserves to Proved Developed Producing Reserves, and can provide
additional PUD locations on the Company's leasehold acreage.

     The Company's Anadarko Basin properties were initially drilled on 640 acre
producing units. Industry has successfully demonstrated to Oklahoma regulators
that deeper wells in the Anadarko Basin will not efficiently drain 640 acres and
have obtained authorization for increased density drilling on smaller acreage
units. Further, under the forced pooling rules in Oklahoma, even if the Company
is not the operator of the property for which increased density drilling has
been approved, the Company may propose to drill and operate additional wells on
the original production unit. Frequently this results in the proposing party
owning a larger portion of newly drilled wells because other Working Interest
owners may decline to participate.

     During the year ended December 31, 1999, the Company drilled 3 Gross (.38
Net) Development Wells in the Anadarko Basin all of which were completed as
commercially productive. The Company's wells typically are completed in horizons
ranging in depth between 7,000 and 15,000 feet.

     ARKOMA BASIN. Most Arkoma Basin reserves are produced from formations at
depths ranging from approximately 3,000 to 8,000 feet.

     During 1999, the Company drilled 2 Gross (.64 Net) Development Wells in the
Arkoma Basin of which 1 Gross (.48 Net) Development Well was completed as
commercially productive. The typical Arkoma Basin well is drilled to a total
depth of approximately 7,500 feet.

  EAST AND WEST TEXAS AREA

     At December 31, 1999, approximately 40.6% (39.2 Bcfe) of the Company's
Proved Reserves were located in the East and West Texas area, including East
Texas and the Goldsmith Adobe Unit in West Texas.

     EAST TEXAS. These reserves are found in the Cotton Valley formation and the
Travis Peak formation. The Cotton Valley formation is generally found at depths
of 8,500 to 10,500 feet in the Company's area of interest. These properties
produce from low permeability reservoirs that generally contain relatively long
life natural gas reserves. A significant portion of the cost to complete Cotton
Valley wells is incurred due to the low permeability of interbedded sandstones
and shales, which requires large hydraulic fracture stimulation, typically of
multiple zones of the producing formation, to obtain the increased production
levels necessary to make such wells commercially viable. The Travis Peak
formation is generally found at a depth of 7,200 feet and principally contains
oil reserves.

     During the year ended December 31, 1999, the Company did not drill any
wells in East Texas.

     GOLDSMITH ADOBE UNIT ("GAU"). The Goldsmith Adobe Unit is in the Permian
Basin in West Texas. The Company owns approximately a 95% Working Interest in
the GAU, which it operates.

     Originally the GAU was drilled on 40 acre spacing units. Previous operators
had drilled several wells on 20 acre spacing units and, based on the results of
this drilling and 20 acre spacing development on adjoining leases, the Company
began a drilling program in July 1994 to develop the GAU on 20 acre spacing
units. Typically, wells drilled by the Company at the GAU are drilled to depths
between 5,600 and 6,000 feet into the Clearfork formation. During 1999, the
Company did not drill any wells at the GAU.

  GULF COAST AREA

     At December 31, 1999, 21.9% (21.2 Bcfe) of the Company's Proved Reserves
were located in the Gulf Coast areas, principally in the Greater Bayou Sorrel
Area in Iberville Parish, Louisiana and at Mustang Island in offshore Gulf of
Mexico. The Company also has participated in exploratory activity in various
parishes throughout Southern Louisiana.

     GREATER BAYOU SORREL AREA. The Greater Bayou Sorrel Area is located
approximately eighty miles west of New Orleans, in Iberville Parish, Louisiana,
in the Atchafalaya River Basin. The target formations of the

                                        7
<PAGE>   9

Company's exploration prospects in this area range from approximately 11,000 to
14,000 feet and include the Marg Vag, Marg Howeii, Camerina, Cib Haz, and Marg
Tex zones. The topography of the surface is river swamp and all work must be
done with barge-mounted drilling rigs and boats. Production platforms are
mounted on pilings. The Company first participated in the successful exploratory
test of the Schwing #1 well in the Company's East Bayou Sorrel prospect in
January 1996. This discovery well was drilled to a total depth of approximately
14,000 feet on the eastern flank of the old Bayou Sorrel Field, which was
discovered by Shell Oil Company in 1954. The old Bayou Sorrel Field was drilled
in the 1950s and 1960s, with a total of 87 wells drilled and produced in
twenty-eight different horizons ranging in depths from 7,000 to 11,100 feet.
During 1997, the Company successfully drilled and completed a second test well,
the Schwing #2. In 1998, the Company successfully drilled and completed the
State Lease 2102 #1 well.

     During 1999, the Company did not drill any wells in the Greater Bayou
Sorrel Area.

     The Company has completed shooting, processing and interpreting, an
approximate 54 square mile 3-D seismic survey over the Greater Bayou Sorrel
Area. The Company has identified additional potential drilling locations for
prospects in this area through interpretation of the 3-D seismic data. However,
the Company's ability to pursue drilling of these sites is currently limited by
the ongoing Chapter 11 proceeding. The Greater Bayou Sorrel Area has produced
and continues to produce significant oil and gas. Because of the difficult
topography, very little seismic data had been acquired prior to the Company's
3-D survey.

     In March 1998, the Company acquired Fortune Natural Resources Corporation's
interests in the East Bayou Sorrel field for approximately $4.5 million in cash.

     MUSTANG ISLAND. The Mustang Island area is located offshore in shallow
state waters in Nueces County, Texas. The Company currently has approximately a
92% working interest in approximately 16,000 gross acres of leases, majority
interests in 2 producing wells, 11 miles of pipeline, and an onshore tank
facility. In addition, the Company participated in a 3-D seismic survey over the
area, which provided approximately 90 square miles of data. Several exploratory
opportunities have been identified from this 3-D seismic data. The Company did
not drill any wells at Mustang Island during 1999.

     In June 1998, the Company acquired Germany Oil Company's interest in six
state leases and one producing well in the Mustang Island area for $.4 million
in cash.

     OTHER SOUTH LOUISIANA. The Company has also participated in exploratory
prospects outside of the Greater Bayou Sorrel area in various parishes in South
Louisiana. During 1999, the Company did not drill any wells in these areas.

OIL AND NATURAL GAS RESERVES

     The estimated reserves and related future net revenues as of December 31,
1999, were prepared by Netherland, Sewell & Associates, Inc. All of the
Company's reserves are located in the continental United States. This reserve
report was prepared using constant prices and costs in accordance with the
published guidelines of the SEC. The net weighted average prices used in the
Company's reserve report at December 31, 1999, were $24.97 per barrel of oil and
$2.26 per Mcf of natural gas. The estimation of reserves and future net revenues
can be materially affected by the oil and gas prices used in preparing the
reserve report. Substantially all of the Company's oil and natural gas
properties are subject to liens, and the remaining oil and natural gas
properties are subject to a negative pledge pursuant to the Company's credit
facility.

     All reserves are evaluated at constant temperature and pressure which can
affect the measurement of natural gas reserves. Estimated operating costs,
development costs, abandonment costs and certain production-related and ad
valorem taxes were deducted in arriving at the estimated future net cash flows.
No provision was made for income taxes. The following estimates set forth
reserves considered to be economically recoverable under normal operating
methods and existing conditions at the prices and operating costs prevailing at
the dates indicated above. The estimates of the PV10% from future net cash flows
can differ from the Standardized Measure of discounted future net cash flows set
forth in the notes to the Financial Statements of the Company, which is
calculated after provision for future income taxes. There can be no assurance
that these estimates are accurate predictions of future net cash flows from oil
and natural gas reserves or their present value.
                                        8

     Reservoir engineering is a subjective process of estimating the volumes of
underground accumulations of oil and natural gas that cannot be measured in an
exact way. The accuracy of any reserve estimates is a function of the quality of
available data and of engineering and geological interpretation and judgment.
Reserve estimates prepared by other engineers might differ from the estimates
contained herein. Results of drilling, testing, and production subsequent to the
date of the estimate may justify revision of such estimate. Future prices
received for the sale of oil and natural gas may be different from those used in
preparing these reports. The amounts and timing of future operating and
development costs may also differ from those used. Accordingly, reserve
estimates are often different from the quantities of oil and natural gas that
are ultimately recovered.

     No estimates of Proved Reserves of oil and natural gas have been filed by
the Company with, or included in any report to, any United States authority or
agency (other than the SEC) since December 31, 1998.

     The following table sets forth certain information for the Company's total
Proved Reserves of oil and natural gas and the PV10% of estimated future net
revenues from such reserves, at December 31, 1999. Also presented is the
Standardized Measure of the Company's total Proved Reserves of oil and natural
gas.

     The Company generally acquires a leasehold interest in the properties to be

and natural gas from a specified area. Lease rentals usually consist of a fixed
annual charge made prior to obtaining production. Once production has been
established, a royalty is paid to the lessor based upon the gross proceeds from
the sale of oil and natural gas. Once wells are drilled, a lease generally
continues as long as production of oil and natural gas continues. In some cases,
leases may be acquired in exchange for a commitment to drill or finance the
drilling of a specified number of wells to predetermined depths.

     Substantially all of the Company's producing oil and natural gas properties
are located on leases held by the Company for an indeterminate number of years
as long as production is maintained. All of the Company's non-producing acreage
is held under leases from mineral owners or a government entity which expire at
varying dates. The Company is obligated to pay annual delay rentals to the
lessors of certain properties in order to prevent the leases from terminating.
Delay rentals were approximately $.9 million for the year ended December 31,
1998 and were approximately $.5 million for the year ended December 31, 1999,
and could increase in future periods depending on the Company's lease
acquisition activities.

TITLE TO OIL AND NATURAL GAS PROPERTIES

     The Company has acquired interests in producing wells and undeveloped
acreage in the form of Working Interests, Royalty Interests, and Overriding
Royalty Interests. To reduce the Company's financial exposure in any one
exploratory prospect, the Company often acquires less than 100% of the Working
Interest in a prospect. Working Interests held by the Company may, from time to
time, become subject to minor liens. Prior to an acquisition, due diligence
investigations are made in accordance with standard practices in the industry,
which may include securing an acquisition title opinion.

PRODUCTION AND SALES PRICES

     The Company produces oil and natural gas solely in the continental United
States. The Company has no obligations to provide a fixed and determinable
quantity of oil and/or natural gas in the future under existing contracts or
agreements. Nor does the Company refine or process the oil and natural gas it
produces, but sells the production to unaffiliated oil and natural gas
purchasing companies in the area in which it is produced. The Company expects to
sell crude oil on a market price basis and to sell natural gas under contracts
to both interstate and intrastate natural gas pipeline companies. The Company
currently sells a significant portion of oil pursuant to a contract with Plains
Marketing and Transportation. See "-- Markets and Customers."

CONTROL OVER PRODUCTION ACTIVITIES

     The Company operated 332 of the 414 producing wells in which it owned an
interest as of December 31, 1999. The non-operated properties are operated by
unrelated third parties pursuant to operating agreements which are generally
standard in the industry. Significant decisions about operations regarding
non-operated properties may be determined by the outside operator rather than by
the Company. If the Company declines to participate in additional activities
proposed by the outside operator under certain operating agreements, the Company
will not receive revenues from, and/or will lose its interest in the activity in
which it declined to participate.

MARKETS AND CUSTOMERS

     The availability of a ready market for any oil and natural gas produced by
the Company and the prices obtained for such oil and natural gas depend upon
numerous factors beyond its control, including the demand for and supply of oil
and natural gas; fluctuations in production and seasonal demand; the
availability of adequate pipeline and other transportation facilities; weather
conditions; economic conditions; imports of crude oil;

                                       11
<PAGE>   13

production by and agreements among OPEC members; and the effects of state and
federal governmental regulations on the import, production, transportation, sale
and taxation of oil and natural gas. The occurrence of any factor that affects a
ready market for the Company's oil and natural gas or reduces the price obtained
for such oil and natural gas, may adversely affect the Company.

     A large percentage of the Company's oil and natural gas sales are made to a
small number of purchasers. The Company normally sells its oil under six month
contracts. For the year ended December 31, 1997, Plains Marketing and
Transportation accounted for 84% of the Company's oil sales, and Crosstex Energy
and GPM Natural Gas Corporation accounted for 20% and 14%, respectively, of the
Company's natural gas sales. For the year ended December 31, 1998, Plains
accounted for 85% of the Company's oil sales, and Crosstex and Aquila Energy
Marketing accounted for 23% and 26%, respectively, of the Company's natural gas
sales. For the year ended December 31, 1999, Plains accounted for 90% of the
Company's oil sales, and Aquila and Crosstex accounted for 21% and 17%,
respectively, of the Company's natural gas sales. The agreement with Plains,
entered into in 1993, provides for Plains to purchase the Company's oil pursuant
to West Texas Intermediate posted prices plus a premium. The Company does not
believe that the loss of any purchaser would have a material adverse effect on
its business because, under prevailing market conditions, such purchaser could
be replaced.

     A portion of the Company's natural gas production is sold pursuant to long
term netback contracts. Under netback contracts, gas purchasers buy gas from a
number of producers, process the gas for natural gas liquids, and sell the
liquids and residue gas. Each producer receives a fixed portion of the proceeds
from the sale of the liquids, and residue gas. The gas purchasers pay for
transportation, processing, and marketing of the gas and liquids, and assume the
risk of contracting pipelines and processing plants in return for a portion of
the proceeds of the sale of the gas and liquids. Generally, because the
purchasers are marketing large volumes of hydrocarbons gathered from multiple
producers, higher prices may be obtained for the gas and liquids. The remainder
of the Company's natural gas is sold on the spot market under short-term
contracts.

REGULATION

     GENERAL. The Company's oil and natural gas exploration, production, and
related operations are subject to extensive rules and regulations promulgated by
federal and state agencies. Failure to comply with such rules and regulations
can result in substantial penalties. The regulatory burden on the oil and gas
industry increases the Company's cost of doing business and affects its
profitability. Because such rules and regulations are frequently amended or
interpreted by federal and state agencies or jurisdictions, the Company is
unable to predict the future cost or impact of complying with such laws.

     EXPLORATION AND PRODUCTION. The Company's exploration and development
operations are subject to various types of regulation at the federal, state, and
local levels. Such regulation includes requiring permits for the drilling of
wells; maintaining bonding requirements in order to drill or operate wells; and
regulating the location of wells, the method of drilling and casing wells, the
surface use and restoration of properties upon which wells are drilled, and the
plugging and abandoning of wells. The Company's operations are also subject to
various conservation regulations and rules to protect the correlative rights of
mineral interest owners. These include the regulation of the size of drilling
and spacing units or proration units, the density of wells which may be drilled,
and the unitization or pooling of oil and natural gas properties. In this
regard, some states allow the forced pooling or integration of tracts to
facilitate exploration, while other states rely on voluntary pooling of land and
leases. In addition, some state conservation laws establish maximum rates of
production from oil and natural gas wells, generally prohibit the venting or
flaring of natural gas, and impose certain requirements regarding the ratability
of production. The effect of these regulations is to limit the amounts of oil
and natural gas the Company can produce from its wells and to limit the number
of wells or the locations at which the Company can drill. Legislation in
Oklahoma and regulatory action in Texas governs the methodology by which the
regulatory agencies establish permissible monthly production allowables. The
Company cannot predict what effect any change in prorationing regulations might
have on its production and sales of natural gas.

     Certain of the Company's Oil, Gas and Mineral Leases are granted by the
federal government and administered by various federal agencies. Such leases
require compliance with detailed federal regulations and orders which regulate,
among other matters, drilling and operations on these leases and calculation and

                                       12
<PAGE>   14

disbursement of royalty payments to the federal government. The Mineral Lands
Leasing Act of 1920 places limitations on the number of acres under federal
leases that may be owned in any one state.

     ENVIRONMENTAL PROTECTION AND OCCUPATIONAL SAFETY. The Company is subject to
numerous federal, state and local laws and regulations governing the release of
materials into the environment or otherwise relating to environmental
protection. These laws and regulations may require the acquisition of a permit
before drilling commences, restrict the types, quantities and concentration of
various substances that can be released into the environment in connection with
drilling and production activities, limit or prohibit drilling activities on
certain lands lying within wilderness, wetlands and other protected areas, and
impose substantial liabilities for pollution resulting from operations.
Moreover, the recent trend toward stricter standards in environmental
legislation and regulation is likely to continue. It is not anticipated that the
Company will be required in the near future to expend amounts that are material
in relation to its total capital expenditure program by reason of environmental
laws and regulations, but because such laws and regulations are frequently
changed, the Company is unable to predict the ultimate cost and effects of such
compliance.

     The Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA"), also known as the "Superfund" law, imposes liability, without regard
to fault or the legality of the original conduct, on certain classes of persons
who are considered to have contributed to the release or threatened release of a
"hazardous substance" into the environment. These persons include the owner or
operator of the disposal site or sites where the release occurred and companies
that disposed or arranged for the disposal of the hazardous substances. Under
CERCLA, such persons or companies may be subject to joint and several
liabilities for the costs of cleaning up the hazardous substances that have been
released into the environment and for damages to natural resources. Also, it is
not uncommon for neighboring landowners and other third parties to file claims
for personal injury, property damage, and recovery of response costs allegedly
caused by the hazardous substance released into the environment.

     In addition, the U.S. Oil Pollution Act of 1990 (the "OPA") and regulations
promulgated pursuant thereto impose a variety of regulations on responsible
parties related to the prevention of oil spills and liability for damages
resulting from such spills. The OPA establishes strict liability for owners of
facilities that are the site of a release of oil into "waters of the United
States." While OPA liability more typically applies to facilities near
substantial bodies of water, at least one district court has held that OPA
liability can attach if the contamination could enter waters that may flow into
navigable waters.

     The Resource Conservation and Recovery Act ("RCRA") and regulations
promulgated thereunder govern the generation, storage, transfer and disposal of
hazardous wastes. RCRA, however, currently excludes from the definition of
hazardous wastes "drilling fluids, produced waters, and other wastes associated
with the exploration, development, or production of crude oil, natural gas, or
geothermal energy." Because of this exclusion, many of the Company's operations
are exempt from RCRA regulation. Nevertheless, the Company must comply with RCRA
regulations for any of its operations that do not fall within the RCRA exclusion
(such as painting activities or use of solvents). On August 8, 1998, EPA added
four petroleum refining wastes to the list of RCRA hazardous wastes. While the
full impact of the rule has yet to be determined, the rule may, as of February
1999, impose increased expenditures and operating expenses on the Company, which
may take on increased obligations relating to the treatment, storage,
transportation and disposal of certain petroleum refining wastes that previously
were not regulated as hazardous wastes. The impact would not likely be any more
burdensome to the Company than to any other similarly situated company involved
in oil and natural gas exploration and production.

     Because oil and natural gas exploration and production, and possibly other
activities, have been conducted at some of the Company's properties by previous
owners and operators, materials from these operations remain on some of the
properties and in some instances require remediation. In addition, the Company
has agreed to indemnify some sellers of producing properties from whom the
Company has acquired reserves against certain liabilities for environmental
claims associated with such properties. While the Company does not believe that
costs to be incurred by the Company for compliance and remediating previously or
currently owned or operated properties will be material, there can be no
guarantee that such costs will not result in material expenditures.

     Additionally, in the course of the Company's routine oil and natural gas
operations, surface spills and leaks, including casing leaks of oil or other
materials occur, and as a result, the Company incurs costs for waste handling
                                       13
<PAGE>   15

and environmental compliance. Moreover, the Company is able to control directly
the operations of only those wells for which it acts as the operator.
Notwithstanding the Company's lack of control over wells in which the Company
owns an interest but is operated by others, the failure of the operator to
comply with applicable environmental regulations may, in certain circumstances,
be attributable to the Company.

     The Company is also subject to laws and regulations concerning occupational
safety and health. While it is not anticipated that the Company will be required
in the near future to expend amounts that are material in the aggregate to the
Company's overall operations by reason of occupational safety and health laws
and regulations, the Company is unable to predict the ultimate cost of
compliance.

     MARKETING AND TRANSPORTATION. Federal legislation and regulatory controls
in the United States have historically affected the price of the natural gas
produced by the Company and the manner in which such production is marketed. The
transportation and sales for resale of natural gas in interstate commerce are
regulated pursuant to the Natural Gas Act of 1938 (the "NGA") and the Federal
Energy Regulatory Commission ("FERC") regulations promulgated thereunder.
Maximum selling prices of certain categories of natural gas, whether sold in
interstate or intrastate commerce, previously were regulated pursuant to The
Natural Gas Policy Act of 1978 ("NGPA"). The NGPA established various categories
of natural gas and provided for graduated deregulation of price controls of
several categories of natural gas and the deregulation of sales of certain
categories of natural gas. All price deregulation contemplated under the NGPA
has already taken place. Subsequently, the Natural Gas Wellhead Decontrol Act of
1989 (the "Decontrol Act") terminated all remaining NGA and NGPA price and
non-price controls on wellhead sales of domestic natural gas on January 1, 1993.
While natural gas producers may currently make sales at uncontrolled market
prices, Congress could re-enact price controls in the future.

     In April 1992, the FERC issued its restructuring rule, known as Order No.
636 ("Order No. 636"), that has had a major impact on pipeline operations,
services, and rates. The most significant provisions of Order No. 636: (i)
required interstate pipelines to provide firm and interruptible transportation
solely on an "unbundled" basis, separate from their sales service, and to
convert each pipeline's bundled firm sales service into unbundled firm
transportation service; (ii) provided for the issuance of blanket certificates
to pipelines to provide unbundled sales service giving all utility customers a
chance to purchase their firm supplies from non-pipeline merchants; (iii)
required that pipelines provide firm and interruptible transportation service on
a basis that is equal in quality for all natural gas supplies, whether purchased
from the pipeline or elsewhere; (iv) required that pipelines provide a new,
non-discriminatory "no-notice" transportation service that largely replicates
the "bundled" sales service previously provided by pipelines; (v) established
two new, generic programs for the reallocation of firm pipeline capacity; (vi)
required that all pipelines offer access to their storage facilities on a firm
and interruptible basis; (vii) provided for pregranted abandonment of pipeline
sales agreements, interruptible and firm short-term (defined as one year or
less) transportation agreements and conditional pregranted abandonment of firm
long-term transportation service; (viii) modified transportation rate design by
requiring that all fixed costs related to transportation be recovered through
the reservation charge; and (ix) provided mechanisms for the recovery by
pipelines of certain transition costs occurring from implementation of Order No.
636.

     The rules contained in Order No. 636, as amended by Order No. 636-A (issued
in August 1992) and Order No. 636-B (issued in November 1992) (collectively,
"Order No. 636"), are far-reaching and complex. While Order No. 636 does not
directly regulate natural gas producers such as the Company, the FERC has stated
that Order No. 636 is intended to foster increased competition within the gas
industry.

OPERATIONAL HAZARDS AND INSURANCE

     The Company's operations are subject to all of the risks inherent in oil
and natural gas exploration, drilling and production. These hazards can result
in substantial losses to the Company due to personal injury and loss of life,
severe damage to and destruction of property and equipment, pollution or
environmental damage, or suspension of operations. The Company maintains
insurance of various types customary in the industry to cover its operations.
The Company believes it is insured prudently against certain of these risks. In
addition, the Company maintains operator's extra expense coverage that provides
coverage for the care, custody and control of wells drilled by the Company. The
Company's insurance does not cover every potential risk associated with the

                                       14
<PAGE>   16

drilling and production of oil and natural gas. The Company does, however,
maintain levels of insurance customary in the industry to limit its financial
exposure in the event of a substantial environmental claim resulting from sudden
and accidental discharges. However, 100% coverage is not maintained. The
occurrence of a significant adverse event, the risks of which are not fully
covered by insurance, could have a material adverse effect on the Company's
financial condition and results of operations. Moreover, no assurance can be
given that the Company will be able to maintain adequate insurance in the future
at rates it considers reasonable. The Company believes that it operates in
compliance with government regulations and in accordance with safety standards
which meet or exceed industry standards.

COMPETITION

     The oil and gas industry is intensely competitive in all of its phases. The
Company, which is a small competitive factor in the industry, encounters strong
competition from major oil companies, independent oil and natural gas concerns,
and individual producers and operators, many of which have financial resources,
staffs, facilities and experience substantially greater than those of the
Company. Furthermore, in times of high drilling activity, exploration for and
production of oil and natural gas may be affected by the availability of
equipment, labor, supplies and by competition for drilling rigs. The Company
cannot predict the effect these factors will have on its operations. The Company
owns no drilling rigs, and it is anticipated that any future drilling will be
conducted by third parties. Furthermore, the oil and gas industry also competes
with other industries in supplying the energy and fuel requirements of
industrial, commercial, and individual consumers.

OFFICE SPACE

     The Company leases approximately 25,000 square feet of office space in
Dallas, Texas. The Company also leases a small amount of office space in Odessa,
Texas, and Yukon, Oklahoma for its business activities.

EMPLOYEES

     At March 23, 2000, the Company had 46 full-time employees. Of these
employees, six are field-related personnel. The Company does not have any
collective bargaining agreements with employees and believes that relations with
its employees are generally satisfactory.

ITEM 3. LEGAL PROCEEDINGS

     Other than the Bankruptcy Court proceedings, the Company is not a party to
any additional material pending legal proceedings.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matters were submitted to a vote of security holders during the fourth
quarter of the fiscal year ended December 31, 1999.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

MARKET INFORMATION

     The Company's Common Stock was traded on the Nasdaq National Market since
September 1, 1995 under the symbol "NEGX". On November 9, 1998, Nasdaq notified
the Company that its common stock would be delisted effective at the close of
business that day for failing to meet the net tangible asset test and minimum
bid price requirements set forth in NASD Marketplace Rules 4450(a)(3) and
4450(a)(5). Nasdaq also advised the Company that its common stock was
immediately eligible for trading on the OTC Bulletin Board through authorized
broker-dealers who had been market makers in the Company's stock during the last
30-days. The Company contacted its OTC Market Makers to notify them of Nasdaq's
action and to facilitate future trading activity. The Company's common stock
currently trades on the OTC Bulletin Board under the symbol "NEGXQ". The
following table sets forth for the periods indicated, the high and low closing
sales prices for the Company's Common Stock, as reported on Nasdaq and/or the
OTC Bulletin Board. The quotations represent prices between dealers in
securities and may not include retail mark-up, mark-down, or commission and may
not represent actual transactions.

HOLDERS

     As of March 23, 2000, the Company had approximately 5,000 record holders of
its shares of Common Stock, including multiple nominee holders for an
undetermined number of beneficial owners.

DIVIDENDS ON COMMON STOCK

     The Company has not paid cash dividends on its Common Stock and does not
expect to declare cash dividends in the foreseeable future. Payment of dividends
is prohibited under bankruptcy rules and regulations. Furthermore, any future
dividends on the Common Stock will be limited by the terms of the Preferred
Stock, which prohibits cash dividends on Common Stock unless all accrued and
unpaid dividends on the preferred stock have been paid, and the terms of the
Company's credit facility with Arnos, Inc., which does not permit dividends on
the Common Stock.

ANNUAL MEETING

     The Company's last annual meeting of shareholders was held on June 4, 1998,
and due to the Company's bankruptcy proceeding, no meeting was held during 1999.
Accordingly, the Company is in violation of its Delaware charter which requires
that an annual meeting of shareholders be held each year or within thirteen

                                       16
<PAGE>   18

months of the last annual meeting of shareholders. Such failure to hold an
annual meeting of shareholders within the designated period could result in an
order by the Delaware Court of Chancery compelling such a meeting if deemed
appropriate. The Company anticipates that no annual meeting of shareholders will
be convened until such time that the Company's bankruptcy proceeding has
concluded.

ITEM 6. SELECTED FINANCIAL DATA

     The following table sets forth selected historical financial and operating
data with respect to the Company as of and for each of the five years in the
period ended December 31, 1999. The Company acquired significant producing oil
and natural gas properties during certain of the periods presented which affects
the comparability of the historical financial and operating data for the periods
presented. The financial data was derived from the historical financial
statements of the Company. This information is not necessarily indicative of the
Company's future performance. The financial data set forth below should be read

(1) Reflects the revenues, results of operations, and production subsequent to
    the dates of acquisitions of various oil and natural gas properties that
    affect the comparability of the data presented. In August 1996, the Company
    completed the Merger with Alexander.

(2) The results of operations for the year ended December 31, 1996 include a
    writedown of oil and natural gas properties of approximately $43.5 million
    ($28.3 million net of deferred income taxes), in accordance with the full
    cost method of accounting, which resulted from the Merger with Alexander.
    The results of operations for the year ended December 31, 1997 included a
    writedown of oil and natural gas properties of approximately $46.4 million
    ($37.5 million, net of deferred income taxes) in accordance with the full
    cost method of accounting. The results of operations for the year ended
    December 31, 1998, include writedowns of oil and natural gas properties of
    approximately $148.4 million in accordance with the full cost method of
    accounting.

(3) See the Glossary included elsewhere herein for the definition of EBITDA.
    EBITDA is not a measure of cash flow as determined by generally accepted
    accounting principles. The Company has included information concerning
    EBITDA because EBITDA is a measure used by certain investors in determining
    the

                                       18
<PAGE>   20

    Company's historical ability to service its indebtedness. However, this
    measure may not be comparable to similarly titled measures of other
    companies. EBITDA should not be considered as an alternative to, or more
    meaningful than, net income or cash flows as determined in accordance with
    generally accepted accounting principles as an indicator of the Company's
    operating performance or liquidity.

(4) For the purposes of calculating the ratio of earnings to, or deficiency of
    earnings over, fixed charges, earnings consist of income before
    extraordinary items and income taxes plus fixed charges, excluding
    capitalized interest. Fixed charges consist of interest expense, capitalized
    interest, the interest component of rent expense, and amortization of debt
    premium, discount and financing costs. The deficiency of earnings over fixed
    charges for the years ended December 31, 1996, 1997 and 1998, were
    approximately $40.0 million, $44.2 million, and $167.9 million,
    respectively.

(5) Due to the discontinuance of the accrual of interest on the Company's
    unsecured Senior Notes during the Bankruptcy proceeding, these measurements
    are not meaningful for the year ended December 31, 1999 and have not been
    presented.

(6) Due to the Chapter 11 proceedings, these measurements are not meaningful for
    the year ended December 31, 1999 and have not been presented. See Notes 1, 4
    and 5 of Notes to Consolidated Financial Statements.

(7) The principal and interest outstanding under the Senior Notes and credit
    facility was classified as current at December 31, 1998. Due to the Chapter
    11 proceedings, this measurement is not meaningful as of December 31, 1999
    and has not been presented. See Note 5 of Notes to Consolidated Financial
    Statements.

(8) Excludes the effects of the full cost ceiling writedowns discussed in Note 2
    above.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS

     The following discussion should be read in conjunction with the Company's
Financial Statements and "Selected Financial Data" and respective notes thereto,
included elsewhere herein. The information below should not be construed to
imply that the results discussed herein will necessarily continue into the
future or that any conclusion reached herein will necessarily be indicative of
actual operating results in the future. Such discussion only represents the best
present assessment by management of the Company.

     On December 4, 1998, certain of the holders of the Senior Notes of the
Company filed an Involuntary Petition for an Order for Relief under Chapter 11
of Title 11 of the United States Bankruptcy Code in the United States Bankruptcy
Court for the Northern District of Texas, Dallas Division, due to non-payment of
interest due December 2, 1998, after expiration of a 30-day grace period. On
December 23, 1998, the Company filed, in the Bankruptcy Court, an Answer to and
Motion to Dismiss the pending Involuntary Petition. However, on February 8,
1999, the Bankruptcy Court denied the Company's Motion to Dismiss the
Involuntary Petition. An Order for Relief was entered by the Bankruptcy Court on
February 11, 1999. As a result of the Chapter 11 proceeding, the Company
discontinued the accrual of interest on the unsecured Senior Notes and
discontinued the accrual of dividends on the unsecured preferred stock.
Approximately $17.7 million additional interest expense would have been
recognized by the Company for 1999 if not for the discontinuation of the
interest accrual on the Senior Notes.

     On August 4, 1999, the Company and the Committee appeared before the
Bankruptcy Court and announced agreement on the process for marketing the
Company and/or its assets. The marketing process culminated in an auction
conducted by the Bankruptcy Court on November 1, 1999. At the auction, bidding
on the Company's oil and gas properties, exclusive of the Company's Lake
Mongoulois and Mustang Island properties, ultimately ended at a high bid of
$96.25 million given by Arnos. The Committee, after review, concluded that it
would recommend to the Court that it accept the high bid of $96.25 million. An
order accepting Arnos as the highest bidder was signed by the Court on November
16, 1999. Arnos filed a motion to close the Purchase and Sale Agreement ("Arnos
PSA") into escrow pending (i) the Court's confirmation of a plan of
reorganization or (ii) in the event a plan of reorganization is not confirmed, a
court ordered closing of the sale of the properties to Arnos. On or about
January 28, 2000 the substantive purchase and sale closing documents were
delivered into the registry of the Court, however, the closing of the Arnos PSA
is still pending as noted. The Court approved this motion and ordered Arnos to
pay into the Court's registry the sum of $61.625 million which equals the
purchase price of $96.25 million less a previously escrowed deposit of $9.625
million and the principal balance of $25 million outstanding under the Company's
secured credit facility with Arnos.

     On February 28, 2000, the Committee Disclosure Statement and Committee Plan
were filed with the Court. The Committee Plan provides for (i) the possibility
of a limited continuation of the Company's oil and gas business operations; (ii)
the creation of a creditors trust to which will be transferred substantially all
of the cash and cash equivalents remaining in the Company, the funds held in the
Registry of the Court from the auction of the Company's properties, and all
causes of action for the payment and primary benefit of certain allowed
administrative, tax, priority and miscellaneous secured and unsecured creditors;
and (iii) payment in full of the secured claims. Both the Committee Plan and
Committee Disclosure Statement are subject to amendment, and a hearing in the
Bankruptcy Court on the Committee Disclosure Statement is scheduled on April 17,
2000.

     On March 14, 2000, the Company Disclosure Statement and Company Plan were
filed with the Court. The Company Plan provides for (i) continuation of the
Company's oil and gas business operations; (ii) payment in full of all secured
claims, including the Arnos secured claim in the amount of $25 million, plus
interest as may be due; (iii) payment of a cash sum not to exceed $10,000 to
certain classes of claimants involved in litigation with the Company if such
class accepts the Company's Plan or, alternatively, if rejected by such class,
cash in the amount of 56.5% of any Allowed Claim in such class; (iv) acquisition
by Arnos of any Senior Notes, not otherwise held by Arnos, in consideration of a
payment equal to 56.5% of the face value of each such bond acquired, or,
alternatively, a pro rata share of the cash which Senior Noteholders would
receive in a liquidation, plus a pro rata beneficial interest in a creditor's
trust consisting of certain causes of action, two properties of the Company and
$250,000 in cash; (v) payment of a cash sum equal to 75% of any Allowed Claim to
trade

                                       20
<PAGE>   22

creditors; (vi) retention by each of the preferred and common shareholder equity
interests; provided that both the preferred and common equity interests may, at
the option of Arnos, be deemed cancelled and reissued to holders in a form to be
determined by Arnos; (vii) purchase by Arnos, or an affiliate of Arnos, of
additionally issued shares of the reorganized Company's common stock to the
extent that Arnos or its affiliate shall own up to 49% of all the issued and
outstanding Common Stock of the reorganized Company; and (viii) amendment to the
Senior Notes Indenture. Both the Company Plan and Company Disclosure Statement
are subject to amendment, and a hearing in the Bankruptcy Court on the Company
Disclosure Statement is scheduled on April 20, 2000.

     The accompanying consolidated financial statements have been prepared on a
going concern basis of accounting and do not reflect any adjustments that might
result should the Company be unable to continue as a going concern. The
Company's prior losses from operations and the related Chapter 11 proceeding
raise concern about its ability to continue as a going concern. The
appropriateness of using the going concern basis is dependent upon, among other
things, (i) confirmation of a plan of reorganization under the Bankruptcy Code
which provides for continuation of the Company's oil and gas operations, (ii)
the ability to achieve profitable operations after such confirmation and (iii)
the ability to generate sufficient cash from operations to meet its obligations.

OVERVIEW

     The revenues generated by the Company's operations are highly dependent
upon the prices of, and demand for, oil and natural gas. The price received by
the Company for its oil and natural gas production depends on numerous factors
beyond the Company's control, including seasonal price fluctuation, the
condition of the U.S. economy, foreign imports, political conditions in other
oil and natural gas producing countries, the actions of the Organization of
Petroleum Exporting Countries and domestic governmental regulations, legislation
and policies. Commodity prices have increased during 1999 as compared to 1998
which has had a positive effect on the Company's revenues, profitability and
cash flows.

YEAR ENDED DECEMBER 31, 1999, COMPARED WITH YEAR ENDED DECEMBER 31, 1998

     Revenues. Total revenues increased by $.9 million (2.3%) to $39.3 million
for 1999 from $38.4 million in 1998. The increase in revenues is due to the
increase in oil and gas prices from the same period in 1998. Average natural gas
prices increased $.06 per Mcf to $2.08 per Mcf for 1999 from $2.02 for 1998, and
average oil prices increased $4.96 per barrel to $17.62 per barrel for 1999 from
$12.66 for 1998. The increase in average prices increased 1999 revenues by
approximately $6.2 million compared to 1998.

     In 1999, the Company produced 1,135 Mbbls of oil, a decrease of 8.3%
compared to 1,238 Mbbls in 1998, and the Company produced 9,266 Mmcf of natural
gas in 1999, a decrease of 17.7% from 11,255 Mmcf in the same period of 1998.
The decrease in oil and gas production was caused by natural production
declines. The Company's ability to offset these natural production declines
through its drilling and exploration program was limited during 1999 due to
Bankruptcy Court restrictions. The reduction in oil production was partially
offset by the successful drilling and completion of the State Lease #2102 well
at the Company's East Bayou Sorrel area which came on line in October of 1998.
The Company expects production to continue to decline unless replaced through
drilling, workovers, recompletions and/or acquisitions.

     Costs and Expenses. Lease operating expenses decreased $2.5 million (29.1%)
to $6.1 million for 1999 from $8.6 million in 1998 primarily due to the
Company's efforts to reduce and control these costs. Lease operating expenses
per Mcfe decreased to $.38 for 1999 from $.46 for 1998 due to the 29.1% decrease
in lease operating expenses which more than offset the 14.0% decline in
equivalent production.

     Production taxes decreased $.4 million (16.0%) to $2.1 million for 1999
compared to $2.5 million for 1998. This decrease principally resulted from tax
exemptions and refunds obtained by the Company.

     Depreciation, depletion and amortization ("DD&A") decreased $5.4 million
(25.4%) to $15.9 million for 1999 compared to $21.3 million for 1998. This
decrease in DD&A is due to the decrease in the depletion rate per Mcfe from
$1.06 in 1998 to $.91 for 1999, caused by the effects on depletion expense of
the full cost ceiling writedowns recorded by the Company during 1998. Also
contributing to the decline in DD&A was the decrease in overall production
discussed above.

     At March 31, June 30, September 30, and December 31, 1998, the net book
value of the Company's oil and natural gas properties exceeded the full cost
ceiling, resulting in non-cash writedowns of the oil and natural gas properties
totaling $148.4 million for the year. These writedowns resulted primarily from
the decline in oil and natural gas prices during 1998, costs incurred on
unsuccessful exploratory wells drilled during such periods and unfavorable
revisions to estimates of oil and gas reserves. The Company did not incur
ceiling writedowns during 1999.

     During 1998, the Company recorded non-recurring restructuring charges of
approximately $1.9 million for severance and related costs resulting from the
restructuring of its executive management team and other personnel changes.

     General and administrative costs decreased $2.0 million (32.8%) to $4.1
million for 1999 compared to $6.1 million for 1998. The decrease in general and
administrative expenses compared to 1998 was primarily due to the Company's
restructuring of its management team and other personnel during 1998 as well as
continuing efforts to control other costs. General and administrative costs per
Mcfe decreased 24.2% to $.25 for 1999 from $.33 for 1998. This decrease per Mcfe
is attributable to the decrease in general and administrative costs noted above
which more than offset the decline in overall production. As discussed in Note 2
to the consolidated financial statements, the Company capitalizes internal
general and administrative costs that can be directly identified with
acquisition, development and exploration activities. The Company's capitalized
general and administrative expenses totaled $1.9 million and $.8 million for the
years ended December 31, 1998 and 1999, respectively.

     Other Income and Expenses. The decrease of $12.5 million in interest
expense to $1.9 million for 1999 from $14.4 million for 1998, was due to the
discontinuation of the accrual of interest on the Senior Notes due to the
Chapter 11 proceeding. Approximately $17.7 million additional interest expense
would have been recognized by the Company if not for the discontinuation of the
interest accrual on the Senior Notes. The average balance of

                                       22
<PAGE>   24

debt outstanding during 1999 was $190.0 million as compared to average debt
outstanding of $180.6 million for 1998. The weighted average interest rate for
1999 was 8.2% for interest accrued compared to 9.9% for 1998. The decline in the
weighted average interest rate is due to the discontinuation of the accrual of
interest on the Senior Notes.

     Reorganization Items. During 1999, the Company incurred $4.7 million of
professional fees and other expenses associated with the Chapter 11 filing. In
addition, the Company wrote off a total of $3.2 million of unamortized debt
issuance costs and premiums related to the Senior Notes due to the Chapter 11
proceeding, and earned approximately $761,000 in interest income on cash
accumulating during the Chapter 11 proceeding.

     Net Income. Net income of $2.0 million was recognized for 1999, compared
with a net loss of $164.5 million for 1998. Net income for 1999 excludes
approximately $17.7 million in interest expense and includes expenses of
approximately $7.2 million, net, relating to the bankruptcy proceeding, as
discussed above. The net loss for 1998 included writedowns of oil and natural
gas properties of $148.4 million. Excluding the effects of these amounts a net
loss of $9.3 million would have been generated for 1999 compared to a net loss
of $16.1 million for 1998.

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

     Revenues. Total revenues decreased by $14.0 million (26.7%) to $38.4
million for 1998 from $52.4 million in 1997. The reduction in revenues is
primarily due to the decrease in commodity prices from the same period in 1997.
Average natural gas prices decreased $.35 per Mcf to $2.02 per Mcf for 1998 from
$2.37 for 1997, and average oil prices decreased $6.51 per barrel to $12.66 for
1998 from $19.17 for 1997. The decrease in average prices reduced 1998 revenues
by approximately $12.0 million compared to 1997.

     Also contributing to the decrease in revenues was the Mmcfe equivalent
decrease in production. In 1998, the Company produced 1,238 Mbbls of oil, an
increase of 11.5% over 1,110 Mbbls in 1997, and 11,255 Mmcf of natural gas, a
decrease of 14.4% over 13,146 Mmcf in the same period of 1997. The increase in
oil production is due primarily to the completion of four GAU wells in the first
quarter of 1998, the completion of the State Lease #2102 well (in the Greater
Bayou Sorrel area) in October of 1998 and the drilling activity on the Company's
Anadarko Basin properties. The decline in gas production is primarily due to the
flush production in 1997 from the drilling program on the East Texas and Arkoma
properties. The Company had limited drilling activity in these areas during
1998.

     Also affecting 1998 production was the temporary shut-in of the East Bayou
Sorrel field to allow for a pipeline repair, which reduced 1998 production by
291 Mmcfe, the 1997 sale of certain non-strategic properties and natural decline
of production not replaced by additional drilling activity. The East Bayou
Sorrel field was also shut-in for seven days to allow for the completion of the
State Lease #2102 and Hurricane George. The Company expects production to
continue to decline unless replaced through drilling, workovers, recompletions
and/or acquisitions.

     Costs and Expenses. Lease operating expenses increased $1.9 million (28.4%)
to $8.6 million for 1998 from $6.7 million for 1997 primarily due to additional
wells brought into production during 1998 and 1997. The Company also entered
into a saltwater disposal lease and $.4 million was paid for this lease during
the fourth quarter of 1998. The increase in lease operating expenses was in part
offset by the 1997 sale of non-strategic properties and the Company's efforts to
reduce operating costs. Lease operating expenses per Mcfe increased to $.46 for
1998 from $.34 for 1997 due to increased costs combined with the Mmcfe
equivalent decline in production during the period.

     Production taxes decreased $.6 million (19.4%) to $2.5 million for 1998
compared to $3.1 million for 1997. This decrease principally resulted from the
decrease in total oil and natural gas revenues discussed above.

     Depreciation, depletion and amortization decreased $1.9 million (8.2%) to
$21.3 million for 1998 compared to $23.2 million for 1997. This decrease is due
to the decrease in the depletion rate per Mcfe from $1.11 in 1997 to $1.06 for
1998. This decrease in the depletion rate was primarily due to the effects on
depletion expense of the full cost ceiling writedowns discussed below in 1998.

                                       23
<PAGE>   25

     At March 31, June 30, September 30, and December 31, 1998, the net book
value of the Company's oil and natural gas properties exceeded the full cost
ceiling, resulting in non-cash writedowns of the oil and natural gas properties
totaling $148.4 million for the year. These writedowns resulted primarily from
the decline in oil and natural gas prices, costs incurred on unsuccessful
exploratory wells drilled during such period and unfavorable revisions to
estimates of oil and gas reserves.

     During 1998, the Company recorded non-recurring charges of approximately
$1.9 million for severance and related costs resulting from the restructuring of
its executive management team, other personnel changes and costs associated with
the Chapter 11 filing.

     General and administrative costs increased $1.7 million (38.6%) to $6.1
million compared to $4.4 million for 1997. The increase in general and
administrative expenses compared to 1997 was primarily due to increased
personnel and office space due to the increase in the scope of the Company's
operations. In 1998, in an effort to reduce general and administrative costs the
Company restructured its executive management team and other personnel. The
Company also renegotiated its office lease and implemented other cost cutting
strategies. The Company's capitalized general and administrative expenses
totaled $1.6 million and $1.9 million for the years ended December 31, 1997 and
1998, respectively. General and administrative costs per Mcfe increased 50.0% to
$.33 for 1998 from $.22 for 1997. This increase per Mcfe is attributable to the
decrease in production, combined with additional general and administrative
costs noted above.

     Other Income and Expenses. The increase of $3.2 million in interest expense
to $14.4 million for 1998 from $11.2 million for 1997, was due to the issuance
of the Series C Notes in August 1997, and interest on borrowings under the
credit facility, partially offset by an increase of $.8 million of interest
costs which were capitalized during 1998 related to the Company's unproved oil
and natural gas properties. The average balance of debt outstanding during 1998
was $180.6 million as compared to average debt outstanding of $133.4 million for
1997. The weighted average interest rate for 1998 was 9.9% compared to 10.3% for
1997. As of December 4, 1998, the Company discontinued the accrual of interest
on unsecured liabilities subject to compromise, which primarily consisted of the
Senior Notes, as a result of filing the Involuntary Petition. Approximately $1.3
million additional interest expense would have been recognized by the Company if
not for the discontinuation of the interest accrual on the Senior Notes.

     Net Loss. A net loss of $164.5 million was generated for 1998, compared
with net loss of $34.3 million for 1997. The net losses for 1998 and 1997
included writedowns of oil and natural gas properties of $148.4 million and
$37.5 million, respectively, net of deferred taxes. Excluding these charges,
income decreased $19.3 million in 1998 compared with 1997 due to the decrease in
operating income and increased interest expense.

LIQUIDITY AND CAPITAL RESOURCES

YEAR ENDED DECEMBER 31, 1999, COMPARED WITH YEAR ENDED DECEMBER 31, 1998

     Net cash provided by operating activities was $27.7 million for the year
ended December 31, 1999, compared to $5.1 million for the same period in 1998.
The increase in cash flow from operating activities is due, in part, to the
increase in income from operations before non-cash charges, resulting from
increased oil and gas revenues from higher commodity prices as well as
significantly lower lease operating expenses and general and administrative
expenses. Also largely contributing to the increase in net cash provided by
operations is the fact that the Company discontinued accruing interest on the
Senior Notes as a result of the Chapter 11 proceeding.

     Net cash used by investing activities was $1.0 million for 1999 compared
with $53.3 million for 1998. The cash used by investing activities for 1999
sharply declined due to the Company's discontinuation of its drilling program
pursuant to Court restrictions.

     No cash was provided by financing activities during 1999 compared with
$24.8 million for the same period in 1998. The net cash provided by financing
activities during 1998 consisted primarily of proceeds from the credit facility.

                                       24
<PAGE>   26

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

     Net cash provided by operating activities was $5.1 million for the year
ended December 31, 1998, compared to $22.9 million for the same period in 1997.
The decrease in cash flow from operating activities is primarily due to the
decrease in income from operations before non-cash charges, resulting from
depressed sales prices for oil and gas and reduced production at such prices.

     Net cash used by investing activities was $53.3 million for 1998 compared
with $75.8 million for 1997. The cash used by investing activities for 1998
included $52.0 million for exploration and development expenditures pursuant to
the Company's drilling program, including acquisitions of leasehold interests
and seismic costs.

     Net cash provided by financing activities was $24.8 million for 1998
compared with $64.7 million for the same period in 1997. The net cash provided
by financing activities during 1998 consisted primarily of proceeds from the
credit facility. In 1997, cash provided by financing activities consisted
primarily of proceeds from the issuance of the Series C Notes.

     The Company's working capital deficit at December 31, 1998, was $197.8
million compared to a working capital surplus at December 31, 1997 of $8.4
million. The decrease in working capital was due primarily to the classification
as a current liability of the $25.0 million due under the Arnos credit facility,
the $166.2 million due on the Senior Notes and the accrued interest on the
Senior Notes.

FUTURE CAPITAL REQUIREMENTS

     During the period of the bankruptcy proceeding, the Company has suspended
its development and exploratory drilling program. The Company has been limited
in its capital expenditures to ordinary course enhancement of current production
through workovers, recompletions, and other production enhancing activities
deemed to be economic given current oil and gas prices. Also during the
bankruptcy period, development drilling is anticipated to be limited to (i)
ordinary course nonoperated wells in which we have limited working interests and
in which the failure to participate may result in drainage, depletion or loss of
current reserves and (ii) operated wells deemed to be economical given current
oil and gas prices. Large expenditures for developmental drilling may require
court approval and none are planned at this time.

     The Company currently expects that existing cash and cash flows from
operations will be sufficient to fund planned capital expenditures for its
existing properties through 2000. However, the Company could require additional
capital to fund any large acquisitions and access to these markets could be
limited due to the Chapter 11 proceeding.

     Subject to Court approval, the Company may seek additional capital, if
required, from traditional reserve base borrowings, equity, and debt offerings
or joint ventures to further develop and explore its properties and to acquire
additional properties. There is no assurance, even if approved by the Court,
that the Company would be able to access additional capital or that, if
available, it will be at prices or on terms acceptable to the Company. In
addition, the Chapter 11 proceeding and restrictions from the Bankruptcy Court
could limit the Company's ability to access additional capital markets.

     Should the Company be unable to access the capital markets or should
sufficient capital not be available, the development and exploration of the
Company's properties could be delayed or reduced and, accordingly, oil and
natural gas revenues and operating results may be adversely affected.

FINANCIAL REPORTING IMPACT OF FULL COST METHOD OF ACCOUNTING

     The Company follows the full cost method of accounting for oil and natural
gas properties. Under such method, the net book value of such properties, less
related deferred income taxes, may not exceed a calculated "ceiling." The
ceiling is the estimated after-tax future net revenues from proved oil and
natural gas properties, discounted at 10% per year. In calculating future net
revenues, prices and costs in effect at the time of the calculation are held
constant indefinitely, except for changes which are fixed and determinable by
existing contracts. The net book value is compared to the ceiling on a quarterly
and yearly basis. The excess, if any, of the net book value above the ceiling is
required to be written off as a non-cash expense. During the years ended

                                       25
<PAGE>   27

December 31, 1997 and 1998, the net book value of the Company's oil and natural
gas properties exceeded the ceiling based on the weighted average prices of
crude oil and natural gas received by the Company resulting in non-cash
writedowns totaling $37.5 million, net of deferred taxes and $148.4 million,
respectively. The Company had no ceiling limitation writedowns during 1999.
There can be no assurance that there will not be additional writedowns in future
periods under the full cost method of accounting as a result of sustained
decreases in oil and natural gas prices or other factors.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, Accounting for Derivative Instruments
and Hedging Activities ("SFAS No. 133"), which will be adopted by the Company
January 1, 2001. The statement will require the Company to recognize all
derivatives on the balance sheet at fair value. Derivatives that are not hedges
must be adjusted to fair value through income. If the derivative is a hedge,
depending on the nature of the hedge, changes in the fair value of derivatives
will either be offset against the change in fair value of the hedged assets,
liabilities, or firm commitments through earnings or recognized in other
comprehensive income until the hedged item is recognized in earnings. The
ineffective portion of a hedge's change in fair value will be immediately
recognized in earnings. The Company is currently evaluating the effect of SFAS
No. 133 on its financial statements.

CHANGES IN PRICES

     The prices received by the Company for its oil and natural gas production
declined dramatically during 1998. In 1998 the prices received for crude oil
reached their lowest level in 50 years and were the lowest inflation-adjusted
oil prices since the Depression. The Company's revenue and value of its oil and
natural gas properties were adversely affected by such prices. However, oil and
gas prices recovered during 1999 and had a positive effect on the results of
operations for 1999. Oil and gas prices are subject to seasonal and other
fluctuations that are beyond the Company's ability to control or predict.

INFLATION

     Although certain of the Company's costs and expenses are affected by the
level of inflation, inflation has not had a significant effect on the Company's
results of operations during the three years ended December 31, 1999.

YEAR 2000

     The year 2000 ("Y2K") problem arose because of computer programs which use
two digits rather than four digits to define a year and which had the potential
to result in errors or system failures. In prior years, the Company discussed
the nature and progress of its plans to become Y2K ready. In 1999, the Company
completed its remediation and testing of systems. As a result of those planning
and implementation efforts, the Company experienced no significant disruptions
in information technology and non-information technology systems and believes
those systems successfully responded to the year 2000 date change. The Company's
expenses during 1999 in connection with remediating its systems were nominal.
The Company is not aware of any material problems resulting from Y2K issues,
either with its products, its internal systems, or the products and services of
third parties. The Company will continue to monitor its computer applications to
ensure that any latent Y2K matters that may arise are addressed promptly.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     In the past, the Company has utilized various derivative instruments and
may do so in the future, principally to hedge the prices received for its gas
production. While the use of hedging arrangements limits the downside risk of
adverse price movements, it may also limit future gains from favorable
movements. The Company addresses market risk by selecting instruments whose
value fluctuations correlate strongly with the underlying commodity being
hedged. Credit risk related to hedging activities is managed by requiring
minimum credit standards for counter parties, periodic settlements, and market
to market valuations. The Company has not been

                                       26
<PAGE>   28

required to provide collateral relating to hedging activities. At December 31,
1998 and 1999, the Company had no hedging or basis swap agreements outstanding.

     At December 31, 1998, the Company had entered into forward sales contracts
with two purchasers covering the future production of natural gas. Deliveries
under these contracts were priced based on NYMEX prices less a differential
whereby the Company may fix the price for deliveries under these contracts at
any time three days prior to the close of the then current contract based on the
NYMEX prices at that time. The Company pays the cost of transportation of the
natural gas to the delivery point specified in the contracts. At December 31,
1999, the Company was not a party to any forward sale contracts.

     The Company's exposure to interest rates relates primarily to its
borrowings under its credit facility. The Company does not currently use
derivatives to manage interest rate risk. Interest is payable on borrowings
under the credit facility based on a floating rate. If short-term interest rates
average 10% higher in 2000 than they were in 1999, the Company's interest
expense would increase by approximately $225,000. This amount was determined by
applying the hypothetical interest rate change to the Company's outstanding
borrowings under the credit facility at December 31, 1999.

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

(1) Messrs. Alexander, David and Mitchell were appointed to the Board on August
    29, 1996, and Mr. Alexander was appointed President and Chief Executive
    Officer of the Company effective November 23, 1998. Messrs. Glass, Hirsch
    and Wasserman were appointed to the Board on December 1, 1998. Pursuant to
    the terms of the Series B Preferred Stock, Series C Preferred Stock and
    Series D Preferred Stock, the holders of a majority of the outstanding
    shares of each series have the right to appoint one member to the Company's

Company. In March 1997 and April 1998, respectively, the Company executed a
similar employment agreement with each of Philip D. Devlin, Vice President,
General Counsel and Secretary and R. Kent Lueders, Vice President, Corporate
Development, (together with Ms. Rutledge's employment agreement, the "Employment
Agreements"). The Employment Agreements each provide that the three-year term
will continuously roll over (so that at any time during the term of such
agreements there is a remaining term of three years, but in no event beyond the
time the executive and/or officer reaches age 65).

     The Employment Agreements define the "change in control" to have occurred
when (i) a person, entity or group becomes the beneficial owner of a majority of
the securities of the Company ordinarily having the right to

                                       32
<PAGE>   34

vote for election of directors, (ii) during any consecutive two year period, the
directors at the beginning of the period (together with directors approved by a
vote of 66 2/3% of such initial directors plus directors previously approved by
such 66 2/3% margin) cease to constitute a majority of the Company's Board of
Directors, (iii) any sale, lease, exchange or transfer of all, or substantially
all, of the Company's assets occurs, or (iv) a merger or consolidation occurs
with the effect that any person, entity or group, or the shareholders thereof,
become the owner of securities of the surviving corporation representing a
majority of the voting power of such surviving corporation for the election of
directors.

     The Employment Agreements provide for a three year employment term during
which the executive and/or officer receives for each year (i) 100% of the
average of the executive's annual base salary at the time in question and the
executive's annual base salary for each of the preceding two years, and (ii)
100% of the average of the bonuses paid to the executive and/or officer for each
of the preceding three fiscal years. If the executive and/or officer is
discharged without cause or resigns for "good reason" (as defined therein) after
a change in control, then in lieu of the compensation described in the preceding
sentence, the executive and/or officer is entitled to a lump sum cash severance
payment equal to three times the sum of (a) the executive's annual base salary
then in effect, (b) the average of cash bonuses for each of the three previous
years, and (c) the average of fully-vested contributions to retirement plans for
such executive and/or officer for each of the three preceding years. In
addition, at such time, all options and all other retirement or pension
contributions or benefits become fully vested and remain fully exercisable for
360 days.

     Pursuant to an agreement with the Company dated December 3, 1998, each of
Ms. Rutledge, Mr. Devlin and Mr. Lueders agreed to terminate their existing
Employment Agreements; provided that no court (including the bankruptcy court)
reduces or dismisses any of the Severance Pay Benefits (described below)
available to such executives pursuant to the Company's Severance Policy.

     In addition to the Employment Agreements discussed above, the Company
entered into an employment agreement with Jim L. David in March 1997, then Vice
President, Exploration for a two year term, commencing with the date of
consummation of the merger of the Company with Alexander Energy Corporation.
Under such agreement, in the event Mr. David resigned for a good reason after a
"change of control" as defined above, or upon the discharge of Mr. David without
cause during the employment term, Mr. David would receive severance benefits
equal to the sum of (i) his annual base salary then in effect, (ii) his last
annual cash bonus and (iii) the average retirement plan contributions by the
Company on his behalf on a fully vested bases for the last two fiscal years,
multiplied by three (3). Mr. David would also have all stock options previously
granted to him become fully vested and exercisable for a three-year period (360
days) following termination. Mr. David's Employment Agreement was terminated in
July, 1998 and the benefits payable under this Employment Agreement were paid
and made a part of his separation agreement. Effective December 1, 1998, Mr.
David was re-employed with the Company as an Assistant to the President;
however, he does not have a new employment agreement in conjunction therewith.

SEVERANCE POLICY

     Effective November 23, 1998, the directors initiated a Severance Policy for
all employees which provides that for a period ending October 31, 2000, all
Eligible Participants shall be entitled to a Severance Pay Benefit up to 18
months (as defined in the Policy) in the event such Eligible Participant is
terminated by the Company for any reason other than "cause" (as defined in the
Policy). The Policy provides that payments to such terminated employee shall be
subject to the employee's execution of a Separation Agreement which shall
include the following provisions:

     (i)   a release of all claims against the Company;

     (ii)  a confidentiality provision; and

     (iii) an agreement to give notice to the Company and not accept or retain
        any further Severance Pay Benefit in the event the Eligible Participant
        shall accept the same or substantially similar employment with any other
        employer.

                                       33
<PAGE>   35

Payments under the Policy shall be made to each such terminated employee on a
monthly basis; provided that in the event the Company is sold pursuant to a
merger or liquidation proceeding and the Eligible Participant is not offered the
same or substantially similar employment, such Severance Pay Benefit shall be
paid to each Eligible Participant in a lump sum. During 1999, no employees were
terminated by the Company who would be eligible for Severance Pay Benefits under
the Policy.

     Pursuant to an Order of the Bankruptcy Court dated September 7, 1999, the
Company's Severance Policy was abated and a Court ordered Severance Program was
put into effect for all employees of the Company. The Severance Program provides
for contingent payments as follows: (a) a "stay-pay" component payable on the
earlier of an employees termination without cause; the closing of a sale of
substantially all the Company's assets or the confirmation of a Plan of
Reorganization; and (b) a "severance" component, whereby upon termination any
employee who does not obtain new employment, or is not offered a permanent job
in Dallas, Texas for a period of at least one year at the same pay and benefits
provided by the Company, shall be entitled to certain severance benefits. The
Order also provided that any employee who participates in the Severance Program
waives and releases any and all claims arising from any current Employment
Agreement with the Company. Effective October 1, 1999, each of Ms. Rutledge, Mr.
Devlin and Mr. Lueders agreed to participate in the Severance Program and void
their Employment Agreements; provided that all benefits described in the
Severance Program are paid to each, respectively, as prescribed. The Order
further provided that Mr. Alexander and Mr. Devlin would not be entitled to any
payments under the Severance Program until the earlier of (i) confirmation of a
Plan of Reorganization, (ii) conversion to a Chapter 7 bankruptcy proceeding or
(iii) termination of their employment by a trustee appointed by the Court.

     In connection with the Severance Program the following payments will be
made to the below listed officers of the Company upon the occurrence of the
contingent event:

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     As the Board of Directors functioned en banc on all matters during 1999,
there are no reportable Compensation Committee interlocks or insider
participation matters affecting the actions of the directors with respect to the
business of the Company.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     Prior to its dissolution in October 1998, the Compensation Committee was
composed of four Directors, including the former President and Chief Executive
Officer of the Company who acted as an ad hoc member. The Compensation Committee
advises the Company's Board of Directors and management concerning compensation
for its executive officers. Upon dissolution of the Compensation Committee, the
Board of Directors acting en banc assumed responsibility for all matters
relating to compensation; provided that directors who are executive officers or
employees of the Company shall abstain from all matters in which they have a
vested interest. Compensation for executive officers is based on the principles
that compensation must be competitive to enable the Company to motivate, attract
and retain highly qualified and talented employees to lead and grow the
Company's business and, at the same time, provide rewards which are closely
linked to the Company's and the individual's performance.

     The Compensation Committee considers management skills, long term
performance, operating results, unusual accomplishments as well as economic
conditions and other external events that affect the Company's operations.

     In addition to salaries, bonuses and stock options are generally granted
once annually based on performance, length of service or other noted
accomplishments in helping to increase the performance, reserves and/or cash

                                       34
<PAGE>   36

flows of the Company. Options are granted under the National Energy Group, Inc.,
1996 Incentive Compensation Plan which was approved by the Board of Directors
and was approved by the shareholders at the 1997 Annual Meeting. Shares have
been issued annually to executives at market price on the grant date. The Board
of Directors believes that the award of long-term stock options aligns the
interests of the executive officers with the interests of the Company by
creating value for the executives through positive results of the Company.
During 1999, no bonuses were granted and no options were given to any executive
officers of the Company. No severance payments were made to any executive
officer whose employment with the Company terminated during 1999 and none are
due and owing as a result of such termination.

     With respect to Mr. Alexander's base compensation, the Board of Directors
recognized that the growth and performance of the Company is dependent on the
efforts and results of its executive officers and in particular its Chief
Executive Officer. Mr. Alexander's base salary was determined to reflect his
increased responsibilities to the Company during the Company's period of
financial instability which eventually culminated in an involuntary bankruptcy
proceeding.

     Under the terms of the Series D Preferred Stock, a change in control of the
Company may occur if any of the events occur that trigger the Series D Preferred
Stock Contingent Voting Rights (as defined) to elect one-half of the Board of
Directors plus one member and if such rights are exercised by such holder.
Pursuant to an order dated February 11, 1999 of the United States Bankruptcy
Court for the Northern District of Texas, the Company was placed into a Title
11, Chapter 11 of the United States Code bankruptcy reorganization proceeding.
Such proceeding gives rise to the Series D Preferred stockholder to exercise its
right to control the Company's Board of Directors. To date, the Series D
Preferred Stockholder has not exercised such right. However, Messrs. Mitchell,
Glass and Hirsch are affiliated with the Series D Preferred Stockholder. See
"Description of Capital Stock -- Series D Preferred Stock."

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     The Company entered into an agreement in 1997 (the "IAC Agreement") with
Icahn Associates Corp. ("IAC"), an affiliate of Mr. Carl C. Icahn, who is a
beneficial owner of more than 5% of the Company's Common Stock. Pursuant to the
IAC Agreement, IAC committed and subsequently spent $10 million to participate
for specified interests in each of the prospects generated or acquired by the
Company through September 30, 1998. Each party is entitled to certain rights of
first refusal in the event that the other party decides to sell all or part of
its participation interest in a prospect in which both parties are
participating. As partial consideration for IAC's obligations under the
participation agreement, the Company has also granted Gascon Partners, an
affiliate of IAC, certain warrants, which became exercisable prior to December
31, 1997 and will expire July 11, 2002, to purchase 300,000 shares of Common
Stock at an exercise price of three dollars ($3.00) per share.

     Effective December 22, 1998, the Company's credit facility and related $25
million outstanding balance was assigned jointly by Bank One Texas, N.A. and
Credit Lyonnais New York Branch Bank to Arnos Corp., another affiliate of Mr.
Carl C. Icahn. During 1999 the Company has paid fees and interest associated
with the credit facility in the amount of $2.1 million to Arnos Corp. Pursuant
to a Bankruptcy Court ordered auction sale on November 1, 1999 of the Company's
oil and gas properties, Arnos Corp. acquired substantially all of such
properties for a purchase price of $96.25 million, which has been deposited into
the registry of the Bankruptcy Court with a final closing pending (i) the
Court's confirmation of a plan of reorganization or (ii) in the event a plan of
reorganization is not confirmed, a court ordered closing of the sale of the
properties to Arnos. The Court approved this motion and ordered Arnos to pay
into the Court's registry the sum of $61.25 million which equals the purchase
price of $96.25 million less the previously escrowed deposit of $9.625 million
and the principal balance of $25 million outstanding under the Arnos credit
facility.

     During the year ended December 31, 1999, the Company sold $18.2 million, or
90.1% of the Company's total oil sales to Plains. KAIM and investment
partnerships associated with KAIM, and other accounts managed by affiliates of
KAIM, own on a fully diluted basis approximately 27.82% of the issued and
outstanding shares of Common Stock of Plains Resources, Inc. The Company has
agreements with Plains that were entered into in 1993 pursuant to which Plains
purchases oil produced from the major oil-producing properties which the Company
operates, at West Texas Intermediate posted prices plus a premium. The premium
is based on Plains purchasing substantially all the production of the Company.
Sales to Plains will account for a significant percentage of the Company's total
oil and natural gas sales in 2000.

                                    GLOSSARY

     Wherever used herein, the following terms shall have the meaning specified.

     Bbl -- One stock tank barrel, or 42 U.S. gallons liquid volume, used herein
in reference to crude oil or other liquid hydrocarbons.

     Bcf -- One billion cubic feet.

     Bcfe -- One billion cubic feet of Natural Gas Equivalent.

     Behind the Pipe -- Hydrocarbons in a potentially producing horizon
penetrated by a well bore the production of which has been postponed pending the
production of hydrocarbons from another formation penetrated by the well bore.
The hydrocarbons are classified as proved but non-producing reserves.

     Developed Acreage -- Acres which are allocated or assignable to producing
wells or wells capable of production.

     Development Well -- A well drilled within the proved area of an oil and
natural gas reservoir to the depth of stratigraphic horizon known to be
productive.

     Dry Well -- A well found to be incapable of producing either oil or natural
gas in sufficient quantities to justify completion as an oil or natural gas
well.

     EBITDA -- Earnings (including interest income and excluding discontinued
operations, extraordinary items, charges resulting from changes in accounting
and significant nonrecurring revenues and expenses) before interest expense,
income taxes, depletion, depreciation and amortization, and the provision for
impairment of oil and natural gas properties. EBITDA is not a measure of cash
flow as determined by generally accepted accounting principles. EBITDA
information has been included in this document because EBITDA is a measure used
by certain investors in determining historical ability to service indebtedness.
EBITDA should not be considered as an alternative to, or more meaningful than,
net income or cash flows as determined in accordance with generally accepted
accounting principles as an indicator of operating performance or liquidity.

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

     Gross Acres or Gross Wells -- The total acres or wells, as the case may be,
in which a Working Interest is owned.

     Infill Well -- A well drilled between known producing wells.

     Mbbl -- One thousand Bbl.

     Mcf -- One thousand cubic feet.

     Mcfe -- One thousand cubic feet of Natural Gas Equivalent.

     Mmcf -- One million cubic feet.

     Natural Gas Equivalent -- The ratio of one Bbl of crude oil to six Mcf of
natural gas.

     Net Acres or Net Wells -- The sum of the fractional Working Interests owned
in Gross Acres or Gross Wells.

     NYMEX -- New York Mercantile Exchange.

     Oil, Gas and Mineral Lease -- An instrument by which a mineral fee owner
grants to a lessee the right for a specific period of time to explore for oil
and natural gas underlying the lands covered by the lease and the right to
produce any oil and natural gas so discovered generally for so long as there is
production in economic quantities from such lands.

                                       48
<PAGE>   50

     OPEC -- Organization of Petroleum Exporting Countries.

     Overriding Royalty Interest -- A fractional undivided interest in an oil
and natural gas property entitling the owner of a share of oil and natural gas
production, in addition to the usual royalty paid to the owner, free of costs of
production.

     PDNP -- Proved developed, nonproducing, or Behind the Pipe reserves.

     Productive Well -- A well that is producing oil or natural gas or that is
capable of production.

     Proved Developed Producing Reserves -- Proved reserves that can be expected
to be recovered from currently producing zones under the continuation of present
operating methods.

     Proved Developed Reserves -- Reserves that can be expected to be recovered
through existing wells with existing equipment and operating methods.

     Proved Reserves -- The estimated quantities of crude oil, natural gas, and
natural gas liquids which geological and engineering data demonstrate with
reasonable certainty to be recoverable in future years from known reservoirs
under existing economic and operating conditions.

     Proved Undeveloped Reserves -- Reserves that are expected to be recovered
from new wells on undrilled acreage, or from existing wells where a relatively
major expenditure is required for completion.

     PUD -- See Proved Undeveloped Reserves.

     PV 10% -- The discounted future net cash flows for Proved Reserves of oil
and natural gas computed on the same basis as the Standardized Measure, but
without deducting income taxes, which is not in accordance with generally
accepted accounting principles. PV 10% is an important financial measure for
evaluating the relative significance of oil and natural gas properties and
acquisitions, but should not be construed as an alternative to the Standardized
Measure (as determined in accordance with generally accepted accounting
principles).

     Revenue Interest -- The interest in a lease or well that receives a
proportionate share of all revenues from that lease or well as identified in the
division order.

     Royalty Interest -- An interest in an oil and natural gas property
entitling the owner to a share of oil and natural gas production free of costs
of production.

     Secondary Recovery -- A method of oil and natural gas extraction in which
energy sources extrinsic to the reservoir are utilized.

     Standardized Measure -- The estimated future net cash flows from Proved
Reserves of oil and natural gas computed using prices and costs, at the date
indicated, after income taxes and discounted at 10%.

     Undeveloped Acreage -- Lease acreage on which wells have not been drilled
or completed to a point that would permit the production of commercial
quantities of oil and natural gas regardless of whether such acreage contains
Proved Reserves.

     Working Interest -- The operating interest which gives the owner the right
to participate in the drilling, producing, and conducting operating activities
on the property and a share of all costs of exploration, development, and
operations and all risks in connection therewith.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Shareholders
National Energy Group, Inc.

     We have audited the accompanying consolidated balance sheets of National
Energy Group, Inc., as of December 31, 1998 and 1999, and the related
consolidated statements of operations, stockholders' equity (deficit), and cash
flows for each of the three years in the period ended December 31, 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 audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of National Energy
Group, Inc., at December 31, 1998 and 1999, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1999, in conformity with accounting principles generally accepted
in the United States.

     The accompanying consolidated financial statements have been prepared
assuming that the Company will continue as a going concern. As discussed in Note
1 of the Notes to the Consolidated Financial Statements, on February 11, 1999,
the United States Bankruptcy Court granted an Involuntary Petition for an Order
for Relief under Chapter 11 of Title 11 of the United States Bankruptcy Code.
This matter raises substantial doubt about the ability of the Company to
continue as a going concern. The financial statements do not include any
adjustments to reflect the possible future effects on the recoverability and
classification of assets or the amounts and classification of liabilities that
may result from the outcome of this uncertainty.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1999

1. BACKGROUND AND BANKRUPTCY FILING

     National Energy Group, Inc. was incorporated under the laws of the State of
Delaware on November 20, 1990. Effective June 11, 1991, Big Piney Oil and Gas
Company and VP Oil, Inc. merged with and into the Company. On August 29, 1996,
Alexander Energy Corporation was merged with and into a wholly-owned subsidiary
of the Company, which subsidiary was merged with and into the Company on
December 31, 1996.

     The Company is an independent energy company which has historically engaged
in the exploration, acquisition, exploitation, development and production of oil
and natural gas properties in major producing basins onshore in Texas,
Louisiana, Oklahoma, Arkansas and offshore in the Gulf of Mexico.

     On December 4, 1998, certain of the holders of the Senior Notes of National
Energy Group, Inc. (the "Company") filed an Involuntary Petition for an Order
for Relief under Chapter 11 of Title 11 of the United States Bankruptcy Code in
the United States Bankruptcy Court for the Northern District of Texas, Dallas
Division, due to non-payment of interest due December 2, 1998, after expiration
of a 30-day grace period. On December 23, 1998, the Company filed, in the
Bankruptcy Court, an Answer to and Motion to Dismiss the pending Involuntary
Petition. The Company's Motion affirmed that it (i) was meeting its obligations
and generally paying its debts as they become due, unless such debts were the
basis of a bona fide dispute and (ii) had arranged with the lender under its
credit facility to borrow additional funds sufficient to pay the interest due on
the Senior Notes, conditioned upon the Court's dismissal of the Involuntary
Petition. However, on February 8, 1999, the Bankruptcy Court denied the
Company's Motion to Dismiss the Involuntary Petition. An Order for Relief was
entered by the Bankruptcy Court on February 11, 1999. The Order for Relief
placed the Company under the protection of the Court and precluded payment of
the interest on the Senior Notes until the conclusion of the Bankruptcy
proceeding. Additionally, payment of liabilities existing as of February 11,
1999 to certain unsecured creditors and dividends in arrears to holders of the
Company's preferred stock and any pending litigation are stayed during the
Bankruptcy proceeding. The Company shall act as debtor-in-possession and will
continue to operate its business and manage its properties in the ordinary
course of business during its Chapter 11 proceeding. As a result of the Chapter
11 proceeding, the Company discontinued the accrual of interest on the unsecured
Senior Notes and discontinued the accrual of dividends on the unsecured
preferred stock. Approximately $17.7 million additional interest expense would
have been recognized by the Company for 1999 if not for the discontinuation of
the interest accrual on the Senior Notes.

     On August 4, 1999, the Company and the unsecured creditors' committee (the
"Committee") appeared before the Bankruptcy Court and announced agreement on the
process for marketing the Company and/or its assets. The Court entered an order
which provided that the Company and the Committee would employ CIBC World
Markets Corp. ("CIBC") to solicit bids for sale of the Company and/or its
assets. The Company assisted CIBC in assembling a data room for potential
bidders to view information regarding the Company's assets. CIBC marketed the
Company's assets pursuant to procedures approved by the Company, the Committee
and the Court. In addition, the Court approved the retention of Netherland,
Sewell & Associates, Inc. to (i) complete its reserve evaluation of the
Company's oil and natural gas properties as of December 31, 1998, (ii) update
the reserve evaluation as of July 1, 1999 and (iii) provide assistance to the
Company, CIBC and prospective buyers during the marketing process. The marketing
process culminated in an auction conducted by the Bankruptcy Court on November
1, 1999. At the auction, bidding on the Company's oil and gas properties,
exclusive of the Company's Lake Mongoulois and Mustang Island properties,
ultimately ended at a high bid of $96.25 million given by Arnos, Corp. ("Arnos")
an affiliated subsidiary of the Company's Series D preferred stockholder. The
Committee, after review, concluded that it would recommend to the Court that it
accept the high bid of $96.25 million. An order accepting Arnos as the highest
bidder was signed by the Court on November 16, 1999. Arnos filed a motion to
close the Purchase and Sale Agreement ("Arnos PSA") into escrow pending (i) the
Court's confirmation of a plan of reorganization or (ii) in the event a plan of
reorganization is not confirmed, a

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BACKGROUND AND BANKRUPTCY FILING (CONTINUED)
court ordered closing of the sale of the properties to Arnos. On or about
January 28, 2000 the substantive purchase and sale closing documents were
delivered into the registry of the Court, however, the closing of the Arnos PSA
is still pending as noted. The Court approved this motion and ordered Arnos to
pay into the Court's registry the sum of $61.625 million which equals the
purchase price of $96.25 million less a previously escrowed deposit of $9.625
million and the principal balance of $25 million outstanding under the Company's
secured credit facility with Arnos.

     On February 28, 2000, the Committee filed with the Court a Joint Disclosure
Statement ("Committee Disclosure Statement") and proposed Plan of Reorganization
(the "Committee Plan"). The Committee Plan provides for (i) the possibility of a
limited continuation of the Company's oil and gas business operations; (ii) the
creation of a creditors trust to which will be transferred substantially all of
the cash and cash equivalents remaining in the Company, the funds held in the
Registry of the Court from the auction of the Company's properties, and all
causes of action for the payment and primary benefit of certain allowed
administrative, tax, priority and miscellaneous secured and unsecured creditors;
and (iii) payment in full of the secured claims. The Committee Plan designates
eight (8) classes of claims and equity interests. The Company's Senior
Noteholders are deemed to be Allowed Class 6 Claims in the Committee's Plan and
are entitled to their pro rata share of the remaining proceeds in the creditors
trust after payment of the secured claims. Following distribution of the
creditors trust fund to the various claimants, the Committee retains the right
to sell the Company's remaining assets or sell to third parties the rights of
the Senior Noteholders to retain between 49% and 95% of the outstanding stock of
the reorganized Company in the form of newly issued additional common stock. In
connection therewith, the Senior Noteholders shall have the right to elect all
members of the Company's Board of Directors for a two (2) year term following
the effective date of the Committee's Plan. The Committee's Plan further
provides that all of the Company's preferred stock shall be converted into
Common Stock at a conversion price of $.25 per share, and the existing common
and preferred equity interests of the Company shall remain in existence. Neither
the Company's preferred shareholders, nor the Company's common shareholders are
entitled to vote on the Committee's Plan and have been deemed for all purposes
to have rejected it in its entirety. Both the Committee Plan and Committee
Disclosure Statement are subject to amendment, and a hearing in the Bankruptcy
Court on the Committee Disclosure Statement is scheduled on April 17, 2000.

     On March 14, 2000, the Company filed with the Court a Joint Disclosure
Statement ("Company Disclosure Statement") and Plan of Reorganization (the
"Company Plan"). The Company Plan provides for (i) continuation of the Company's
oil and gas business operations; (ii) payment in full of all secured claims,
including the Arnos secured claim in the amount of $25 million, plus interest as
may be due; (iii) payment of a cash sum not to exceed $10,000 to certain classes
of claimants involved in litigation with the Company if such class accepts the
Company's Plan or, alternatively, if rejected by such class, cash in the amount
of 56.5% of any Allowed Claim in such class; (iv) acquisition by Arnos of any
Senior Notes, not otherwise held by Arnos, in consideration of a payment equal
to 56.5% of the face value of each such bond acquired, or, alternatively, a pro
rata share of the cash which Senior Noteholders would receive in a liquidation,
plus a pro rata beneficial interest in a creditor's trust consisting of certain
causes of action, two properties of the Company and $250,000 in cash; (v)
payment of a cash sum equal to 75% of any Allowed Claim to trade creditors; (vi)
retention by each of the preferred and common shareholder equity interests;
provided that both the preferred and common equity interests may, at the option
of Arnos, be deemed cancelled and reissued to holders in a form to be determined
by Arnos; (vii) purchase by Arnos, or an affiliate of Arnos, of additionally
issued shares of the reorganized Company's common stock to the extent that Arnos
or its affiliate shall own up to 49% of all the issued and outstanding common
stock of the reorganized Company; and (viii) amendment to the Senior Notes
Indenture. The Company's Plan further proposes that the Company's existing
officers and directors shall continue as the officers and directors of the
reorganized Company until otherwise replaced as provided in the Company's
bylaws.

                               DECEMBER 31, 1999

1. BACKGROUND AND BANKRUPTCY FILING (CONTINUED)
Neither the Company's preferred shareholders, nor the Company's common
shareholders are entitled to vote on the Company's Plan and have been deemed for
all purposes to have rejected it in its entirety. Both the Company's Plan and
Disclosure Statement are subject to amendment, and a hearing in the Bankruptcy
Court on the Disclosure Statement is scheduled on April 20, 2000.

     Pursuant to an Order of the Bankruptcy Court dated September 7, 1999, the
Company's severance policy was abated and a Court ordered severance program was
put into effect for all employees of the Company ("Severance Program"). The
Severance Program provides for contingent payments as follows: (a) a "stay-pay"
component payable on the earlier of an employees termination without cause; the
closing of a sale of substantially all the Company's assets or the confirmation
of a plan of reorganization; and (b) a "severance" component, whereby upon
termination any employee who does not obtain new employment, or is not offered a
permanent job in Dallas, Texas for a period of at least one year at the same pay
and benefits provided by the Company, shall be entitled to certain severance
benefits. The Order also provided that any employee who participates in the
Severance Program waives and releases any and all claims arising from any
current Employment Agreement with the Company. Certain employees are not
entitled to any payments under the Severance Program until the earlier of (i)
confirmation of a Plan of Reorganization, (ii) conversion to a Chapter 7
bankruptcy proceeding or (iii) termination of their employment by a trustee
appointed by the Court. Maximum potential payments due to employees under the
Severance Program total approximately $2.2 million.

     The accompanying consolidated financial statements have been prepared on a
going concern basis of accounting and do not reflect any adjustments that might
result should the Company be unable to continue as a going concern. The
Company's prior losses from operations and the related Chapter 11 proceeding
raise concern about its ability to continue as a going concern. The
appropriateness of using the going concern basis is dependent upon, among other
things, (i) confirmation of a plan of reorganization under the Bankruptcy Code
which provides for continuation of the Company's oil and gas operations, (ii)
the ability to achieve profitable operations after such confirmation and (iii)
the ability to generate sufficient cash from operations to meet its obligations.

     During 1999, the Company incurred professional fees and other expenses of
$4.7 million and wrote off $3.2 million of unamortized debt issuance costs and
premium associated with the Senior Notes due to the bankruptcy proceedings. At
December 31, 1999, substantially all of the Company's unsecured liabilities are
subject to compromise under the terms of the bankruptcy proceeding. During 1999,
the Company recognized interest income of approximately $761,000 on cash
balances accumulating during the Chapter 11 proceeding.

Consolidation

     The consolidated financial statements include the accounts of National
Energy Group, Inc., and its subsidiaries. All significant intercompany
transactions and balances have been eliminated.

Accounting Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.

Cash and Cash Equivalents

     Cash and cash equivalents may include demand deposits, short-term
commercial paper, and/or money-market investments with maturities of three
months or less when purchased. At December 31, 1999, all cash and cash
equivalents were invested with Bank One, Texas, N.A.

Oil and Natural Gas Properties

     The Company utilizes the full cost method of accounting for its crude oil
and natural gas properties. Under the full cost method, all productive and
nonproductive costs incurred in connection with the acquisition, exploration,
and development of crude oil and natural gas reserves are capitalized and
amortized on the units-of-production method based upon total proved reserves.
The costs of unproven properties are excluded from the amortization calculation
until the individual properties are evaluated and a determination is made as to
whether reserves exist. Conveyances of properties, including gains or losses on
abandonments of properties, are treated as adjustments to the cost of crude oil
and natural gas properties, with no gain or loss recognized.

     Under the full cost method, the net book value of oil and natural gas
properties, less related deferred income taxes, may not exceed the estimated
after-tax future net revenues from proved oil and natural gas properties,
discounted at 10% per year (the ceiling limitation). In arriving at estimated
future net revenues, estimated lease operating expenses, development costs,
abandonment costs, and certain production related and ad-valorem taxes are
deducted. In calculating future net revenues, prices and costs in effect at the
time of the calculation are held constant indefinitely, except for changes which
are fixed and determinable by existing contracts. The net book value is compared
to the ceiling limitation on a quarterly and yearly basis. The excess, if any,
of the net book value above the ceiling limitation is required to be written off
as a non-cash expense. During 1997 and 1998, the net book value of the Company's
oil and natural gas properties exceeded the ceiling limitation resulting in non-
cash writedowns totaling $46.4 million and $148.4 million, respectively. The
Company did not incur ceiling limitation writedowns during 1999. There can be no
assurance that there will not be additional writedowns in future periods under
the full cost method of accounting as a result of sustained decreases in oil and
natural gas prices or other factors.

     Oil and natural gas properties excluded from the ceiling limitation consist
primarily of unevaluated acreage, acquisition costs, and related seismic and
other geological and geophysical costs (unproven properties). During 1998,
unproven properties with a carrying value of approximately $32.0 million were
transferred to proved properties, largely as a result of drilling activities,
and became subject to the full cost ceiling limitation. At December 31, 1998,
due to uncertainty relating to the Company's ability to obtain Court approval
for exploration of its remaining portfolio of unproven properties and due to low
oil prices which make the projects uneconomical,

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
the remaining carrying value of the unproven properties, approximately $9.1
million, was transferred to proved properties and became subject to the ceiling
limitation.

     The Company has capitalized internal costs of $1,582,021, $1,950,914 and
$814,476 for the years ended December 31, 1997, 1998, and 1999, respectively.
Such capitalized costs include salaries and related benefits of individuals
directly involved in the Company's acquisition, exploration, and development
activities based on the percentage of their time devoted to such activities.
During the years ended December 31, 1997 and 1998, the Company capitalized
interest costs of $2,545,617 and $3,371,279, respectively, related to its
unproved oil and gas properties. The Company did not capitalize interest during
1999.

Other Property and Equipment

     Other property and equipment includes furniture, fixtures, and other
equipment. Such assets are recorded at cost and are depreciated over their
estimated useful lives using the straight-line method.

     Maintenance and repairs are charged against income when incurred; renewals
and betterments, which extend the useful lives of property and equipment, are
capitalized.

Income Taxes

     Deferred tax assets and liabilities are determined based on differences
between financial reporting and tax bases of assets and liabilities and are
measured using enacted tax rates. The effect on deferred tax assets and
liabilities of a change in tax rate is recognized in the period that includes
the enactment date. The measurement of deferred tax assets is adjusted by a
valuation allowance, if necessary, to recognize the extent to which, based on
available evidence, the future tax benefits more likely than not will be
realized.

Financial Instruments

     The Company does not hold or issue financial instruments for trading
purposes.

     See Notes 4 and 5 for disclosure of the fair value of borrowings under the
Company's credit facility and the 10 3/4% Senior Notes, respectively.

     The Company from time to time utilizes certain derivative financial
instruments to hedge future gas prices. (Note 9). Gains and losses arising from
the use of these instruments are deferred until realized and are reported as oil
and natural gas sales.

     The Company's marketable securities are classified as available-for-sale.
Available-for-sale securities are carried at fair value, with the unrealized
gains and losses, net of tax, reported as a separate component of stockholders'
equity. Realized gains and losses and declines in value judged to be
other-than-temporary are included in income. The cost of securities sold is
based on the specific identification method.

     The following is a summary of available-for-sale securities at December 31,
1998 and 1999:

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
     The Company had no sales of marketable securities during 1997, 1998 or
1999.

     The Company's investment in marketable securities is comprised of
securities of another independent oil and gas company.

     The Company sells crude oil and natural gas to various customers. In
addition, the Company participates with other parties in the operation of crude
oil and natural gas wells. Substantially all of the Company's accounts
receivable are due from either purchasers of crude oil and natural gas or
participants in crude oil and natural gas wells for which the Company serves as
the operator. Generally, operators of crude oil and natural gas properties have
the right to offset future revenues against unpaid charges related to operated
wells. Crude oil and natural gas sales are generally unsecured.

     Allowances for bad debt totaled approximately $150,000 and $149,000 at
December 31, 1998 and 1999, respectively. At December 31, 1998 and 1999, the
carrying value of the Company's accounts receivable approximates fair value.

Natural Gas Production Imbalances

     The Company accounts for natural gas production imbalances using the sales
method, whereby the Company recognizes revenue on all natural gas sold to its
customers notwithstanding the fact that its ownership may be less than 100% of
the natural gas sold.

Stock Options

     The Company has elected to follow Accounting Principles Board Opinion No.
25, Accounting for Stock Issued to Employees, in accounting for its employee
stock options. Under APB 25, if the exercise price of an employee's stock
options equals or exceeds the market price of the underlying stock on the date
of grant, no compensation expense is recognized.

Earnings (Loss) Per Share

     Earnings (loss) per share is computed in accordance with Financial
Accounting Standards Board Statement No. 128, Earnings per Share. Basic earnings
per share data is computed by dividing net income (loss) applicable to common
shareholders by the weighted average number of common shares outstanding and
excludes any dilutive effects of options, warrants, and convertible securities.
Shares issuable upon exercise of options and warrants are included in the
computation of diluted earnings per common and common equivalent share to the
extent that they are dilutive. Diluted earnings per share computations also
assume the conversion of the Company's preferred stock (Note 7) if such
conversion has a dilutive effect. For the years ended December 31, 1997, 1998,
and 1999, neither the common equivalent shares nor the assumed conversion of the
preferred stock had a dilutive effect on the loss per share calculations.
Accordingly, both basic and diluted loss per share calculations for such periods
are based on the weighted average number of common shares outstanding during
each year.

Comprehensive Income

     Comprehensive income is defined as the change in equity of a business
enterprise during a period from transactions and other events and circumstances
from non-owner sources. For 1997, 1998 and 1999, the differences between the
Company's net earnings and total comprehensive income were not material.

Recent Accounting Pronouncements

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, Accounting for Derivative Instruments
and Hedging Activities, ("SFAS No. 133") which will be adopted by the Company
January 1, 2001. The Statement will require the Company to recognize all
derivatives on the balance sheet at fair value. Derivatives that are not hedges
must be adjusted to fair value through income. If the derivative is a hedge,
depending on the nature of the hedge, changes in the fair value of derivatives
will either be offset against the change in fair value of the hedged assets,
liabilities, or firm commitments through earnings or recognized in other
comprehensive income until the hedged item is recognized in earnings. The
ineffective portion of a hedge's change in fair value will be immediately
recognized in earnings. The Company is currently evaluating the effect of SFAS
No. 133 on its financial statements.

Reclassifications

     Certain previously reported amounts have been reclassified to conform with
the current presentation.

3. ACQUISITIONS AND DISPOSALS

     In March 1998, the Company acquired Fortune Natural Resources Corporation's
interests in the East Bayou Sorrel field for approximately $4.5 million in cash.
In June 1998, the Company acquired Germany Oil Company's interest in six state
leases and one producing well in the Mustang Island area for $.4 million in
cash. These acquisitions did not have a significant impact on the Company's
results of operations for 1998.

     In December 1999, the Company sold its interest at an oil and gas auction
in 142 marginal and non-producing oil and gas properties to various purchasers.
Net proceeds from this sale approximated $3.0 million. The sale of these
properties did not have a significant impact on the Company's results of
operations for 1999.

4. CREDIT FACILITIES

     In 1996, the Company and its subsidiaries, NEG-OK and Boomer Marketing,
entered into an amended credit facility with Bank One, as Bank and
Administrative Agent, and the Credit Lyonnais New York Branch, as Bank and
Syndication Agent (collectively, the "Banks"). The credit facility had a
borrowing base of $25.0 million, maturing August 29, 2000.

     The Company granted liens to the Banks on substantially all of the
Company's oil and natural gas properties, whether currently owned or hereafter
acquired, and a negative pledge on all other oil and natural gas properties. The
credit facility requires, among other things, semiannual engineering reports
covering oil and natural gas properties, and maintenance of certain financial
ratios, including the maintenance of a minimum interest coverage, a current
ratio, and a minimum tangible net worth.

     The credit facility contains other covenants prohibiting cash dividends,
distributions, loans, or advances to third parties, except that cash dividends
on preferred stock will be allowed so long as no event of default exists or
would exist as a result of the payment thereof.

     On December 7, 1998, Bank One and Credit Lyonnais gave notice to the
Company that all outstanding obligations under the credit facility were
accelerated and were immediately due and payable due to certain unspecified
Events of Default as defined in the loan agreement.

     Effective December 22, 1998, the credit facility and all associated liens
were assigned by the Banks to Arnos, Inc., ("Arnos") an affiliated subsidiary of
the Company's Series D Preferred Stockholder. In a letter

                               DECEMBER 31, 1999

4. CREDIT FACILITIES (CONTINUED)
dated December 23, 1998, Arnos (1) rescinded the acceleration of the loan, (2)
waived all defaults existing at that time and (3) made sufficient borrowings
available to pay the interest on the Senior Notes that was due on November 2,
1998 conditioned upon the Bankruptcy Court's dismissal of the Involuntary
Petition. The Company is currently paying interest under the Arnos credit
facility. The Company had $25,000,000 outstanding under the Arnos credit
facility as of December 31, 1999 and 1998. At December 31, 1999 and 1998, the
Company was in violation of the minimum interest coverage ratio and current
ratio covenants under the Arnos credit facility and as a result has classified
the borrowings under the credit facility as a current liability.

     On August 4, 1999, the Company and the Committee appeared before the
Bankruptcy Court and announced agreement on the process for marketing the
Company and/or its assets. The marketing process culminated in an auction
conducted by the Bankruptcy Court on November 1, 1999. At the auction, bidding
on the Company's oil and gas properties, exclusive of the Company's Lake
Mongoulois and Mustang Island properties, ultimately ended at a high bid of
$96.25 million given by Arnos. The Committee, after review, concluded that it
would recommend to the Court that it accept the high bid of $96.25 million. An
order accepting Arnos as the highest bidder was signed by the Court on November
16, 1999. Arnos filed a motion to close the Purchase and Sale Agreement ("Arnos
PSA") into escrow pending (i) the Court's confirmation of a plan of
reorganization or (ii) in the event a plan of reorganization is not confirmed, a
court ordered closing of the sale of the properties to Arnos. The Court approved
this motion and ordered Arnos to pay into the Court's registry the sum of
$61.625 million which equals the purchase price of $96.25 million less the
previously escrowed deposit of $9.625 million and the principal balance of $25
million outstanding under the Arnos credit facility.

     At December 31, 1999, the fair value of borrowings under the Arnos credit
facility approximates the carrying value of the liability.

5. 10 3/4 SENIOR NOTES DUE 2006

     In 1996, the Company issued $100 million aggregate principal amount of
unregistered Series A 10 3/4% Senior Notes due 2006 which were exchanged in 1997
for registered Series B 10 3/4% Senior Notes due 2006 with substantially
identical terms. Collectively, the Series A Notes and Series B Notes are
referred to as the Series A/B Notes." In August 1997, the Company issued $65.0
million aggregate principal amount of its unregistered Series C 10 3/4% Senior
Notes. In December 1997, the Company exchanged substantially all of the Series
A/B Notes and all of the Series C Notes for registered Series D 10 3/4% Senior
Notes due 2006. The Series D Notes are substantially identical to the Series A/B
Notes and the Series C Notes. The Series A/B Notes, the Series C Notes and the
Series D Notes are collectively referred to as the "Senior Notes." The Senior
Notes bear interest at an annual rate of 10 3/4%, payable semiannually in
arrears on May 1 and November 1 of each year. The Senior Notes are senior,
unsecured obligations of the Company, ranking pari passu with all existing and
future senior indebtedness of the Company, and senior in right of payment to all
future subordinated indebtedness of the Company. Subject to certain limitations
set forth in the indenture covering the Senior Notes (the "Indenture"), the
Company and its subsidiaries may incur additional senior indebtedness and other
indebtedness.

     Due to the non-payment of interest due December 2, 1998, the Notes were in
default at December 31, 1998 and 1999, and have been classified as a current
liability in the accompanying December 31, 1998 balance sheet.

     On December 4, 1998, certain holders of the Senior Notes filed an
Involuntary Petition for an Order for Relief under Chapter 11 of Title 11 of the
United States Bankruptcy Code. See Note 1. Accrual of interest on the Senior
Notes has been discontinued during the Chapter 11 proceeding. Approximately

interest expense would have been recognized by the Company during 1999 if not
for the discontinuation of the interest accrual.

     During 1999, the Company wrote off the remaining $3.2 million of
unamortized issuance premiums and deferred debt issuance costs associated with
the Senior Notes in accordance with the provisions of SOP 90-7.

     The Indenture contains certain covenants limiting the Company with respect
to the following: (i) assets sales; (ii) restricted payments; (iii) the
incurrence of additional indebtedness and the issuance of certain redeemable
preferred stock; (iv) liens; (v) sale and leaseback transactions; (vi) lines of
business; (vii) dividend and other payment restrictions affecting subsidiaries;
(viii) mergers and consolidations; and (ix) transactions with affiliates.

     At December 31, 1999, the fair value of the Senior Notes, as determined by
quoted market prices, was approximately $82.5 million.

6. COMMITMENTS AND CONTINGENCIES

     The Company leases office space under an operating lease. Rental expense
charged to operations was approximately $275,000, $364,000 and $449,000 during
the years ended December 31, 1997, 1998 and 1999, respectively. Minimum lease
payments under future operating lease commitments at December 31, 1999, are as
follows:

     The Series B has a liquidation and dividend preference over the Company's
Common Stock. The Series B has a 10% dividend, payable semi-annually. In
December 1998, the Board of Directors declared a dividend on Series B to be made
in shares of Series B. To date, the dividends have not been paid and therefore
there are $193,435 dividends in arrears at December 31, 1999, which are
unsecured claims subject to compromise for purposes of the Chapter 11
proceeding. The Series B is redeemable by the Company at $100.00 per share, plus
accrued and unpaid dividends; provided, however, that the Company cannot redeem
any shares of Series B unless and until all outstanding shares of the Series C
have been redeemed by the Company. The holders of Series B currently have the
right to appoint one member to the Company's Board of Directors.

     In December 1998, the Board of Directors declared a dividend on Series C to
be made in shares of Series C. To date, the dividend is unpaid and therefore
there are $120,750 dividends in arrears at December 31, 1999, which are
unsecured claims subject to compromise for purposes of the Chapter 11
proceeding. The Series C is redeemable by the Company at $100.00 per share, plus
accrued and unpaid dividends. The holders of the Series C currently have the
right to appoint one member to the Company's Board of Directors.

     The holders of Series B and C, respectively, are entitled to one vote for
each share as to matters upon which by law they are entitled to vote as a class.
The approval of a majority of the Series B and C, respectively, each voting
separately as a class, is required to (i) make changes to the Company's
Certificate of Incorporation or By-Laws which adversely affect the Series B or
C, (ii) authorize or issue additional shares of Series B or C, (iii) issue
preferred stock equal to or senior to the Series B or C as to dividends or
liquidation, (iv) subject to certain exceptions, to effect an extraordinary
transaction that requires a vote of the Company stockholders. As a result, a
class vote of the holders of Series C, as well as the Series B, would be
required for the Company to merge or be acquired and may therefore delay, deter,
or prevent a change in control of the Company.

     On August 29, 1996, the Company closed the sale for $10.0 million to High
River Limited Partnership of 100,000 shares of its Convertible Preferred Stock,
Series D, $1.00 par value per share and warrants to purchase 700,000 shares of
Common Stock exercisable immediately at $2.50 per share, which warrants expire
five years

from their date of issuance. The Series D Preferred Stock is convertible into
4,444,444 shares of Common Stock, based upon a conversion price of $2.25 per
share.

     The holder of the Series D is entitled to one vote for each share when
entitled to vote as described below and as to matters upon which by law it is
entitled to vote as a class. The holder of Series D has the right to appoint one
member to the Board of Directors. The Company may not, without the consent of
the director appointed by the holder of Series D, voluntarily file for
protection under federal or other bankruptcy laws. In addition, the holder of
Series D currently has the right to choose to appoint one-half of the members of
the Board of Directors plus one member (including the member appointed by the
Series D) if it elects to exercise such right. Currently, the holder of the
Series D has appointed a total of three directors to the Board.

     On August 29, 1996, simultaneously with the closing of the sale for $10.0
million of the Series D to High River, the Company also closed the sale for $5.0
million to two insurance companies and four affiliates of Kayne, Anderson
Investment Management, Inc., a registered investment adviser, of 50,000 shares
of Convertible Preferred Stock, Series E, $1.00 par value per share and warrants
to purchase 350,000 shares of the Common Stock exercisable immediately at $2.50
per share, which warrants expire five years from their date of issuance. The
Series E Preferred Stock is convertible into 2,222,222 shares of Common Stock,
based upon a conversion price of $2.25 per share. The Series E will vote
together with the Common Stock on all matters submitted to the holders of Common
Stock and shall have that number of votes per share equal to the number of
shares of Common Stock into which such share is convertible as of the record
date for the vote.

     In October 1997, 13,813 shares of Series B Preferred Stock, 17,000 shares
of Series C Preferred Stock and 40,500 shares of Series E Preferred Stock were
converted into approximately 3.5 million shares of Common Stock.

  Common Stock

     Holders of Common Stock are entitled to one vote for each share held of
record on all matters voted on by stockholders. The shares of the Common Stock
do not have cumulative voting rights, which means that the holders of more than
50% of the shares of the Common Stock voting for the election of the directors
can elect all of the directors to be elected by holders of the Common Stock, in
which event the holders of the remaining shares of Common Stock will not be able
to elect any director. Upon any liquidation, dissolution, or winding-up of the
affairs of the Company, holders of the Common Stock would be entitled to
receive, pro rata, all of the assets of the Company available for distribution
to stockholders, after payment of any liquidation preference of any Preferred
Stock that may be issued and outstanding at the time. Holders of the Common
Stock have no subscription, redemption, sinking fund, or preemptive rights.

Warrants

     During 1996, the Company issued warrants to purchase 1,050,000 shares of
Common Stock with exercise prices of $2.50 per share to the purchasers of the
Series D preferred stock and Series E preferred stock and issued warrants to
purchase 300,000 shares of Common Stock with exercise prices of $2.875 per share
to financial advisors in connection with this transaction. In connection with
the Company's merger with Alexander Energy in 1996, the Company issued warrants
to purchase 800,000 shares of Common Stock to two financial advisors. Warrants
to purchase 700,000 shares have an exercise price of $2.875 per share while
warrants to purchase 100,000 shares have an exercise price of $4.09 per share.
The Company also assumed 396,015 warrants to purchase common stock at prices
ranging from $2.07 to $3.00 in the Alexander merger. During 1997, 353,515 of
these warrants were exercised and the remainder expired during 1998. During
1997, the Company issued

     Statement of Financial Accounting Standards No. 123, Accounting for Stock
Based Compensation, requires the disclosure of pro forma net income and earnings
per share information computed as if the Company had accounted for its employee
stock options granted subsequent to December 31, 1994, under the fair value
method set forth in SFAS 123. The fair value for these options was estimated at
the date of grant using a Black-Scholes option pricing model with the following
weighted-average assumptions for 1997 and 1998, respectively: risk-free interest
rates of 5.5% and 5.5%, a dividend yield of 0%, and volatility factors of .53
and .53. In addition, the fair value of these options was estimated based on an
expected life of three to five years for options granted by the Company.

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information follows (in thousands except for earnings per share
information):

Stock Purchase Plan

     During 1998, the Company's shareholders approved the Company's Employee
Stock Purchase Plan ("ESPP"). Pursuant to the ESPP, employees can purchase the
common stock of the Company at a specified price through payroll deductions
during an offering period, currently established on a semi-annual basis. In June
1998, approximately 46,000 shares were issued to employees under the ESPP.
During 1999, no shares were issued to employees under the ESPP.

     At December 31, 1999, the Company had net operating loss carryforwards
available for federal income tax purposes of approximately $89.3 million which
begin expiring in 2000. Utilization of approximately $31.0 million of the net
operating loss carryforwards is subject to various limitations because of
previous changes in control of ownership (as defined in the Internal Revenue
Code) of the Company and Alexander Energy. Additional net operating loss
limitations may be imposed as a result of subsequent changes in stock ownership
of the Company. Bankruptcy proceedings may eliminate all or a portion of the
Company's net operating loss carryforwards. For federal income tax purposes, the
Company also has statutory depletion carryforwards of $3.8 million, which do not
expire.

9. NATURAL GAS HEDGING ACTIVITIES AND FORWARD SALES CONTRACTS

     While the use of financial hedging arrangements limits the downside risk of
adverse price movements, it may also limit future gains from favorable
movements. The Company addresses market risk by selecting instruments whose
value fluctuations correlate strongly with the underlying commodity being
hedged. Credit risk related to hedging activities is managed by requiring
minimum credit standards for counterparties, periodic settlements, and mark to
market valuations. The Company has not been required to provide collateral
relating to its hedging activities.

     At December 31, 1999, the Company had not entered into any forward sales
contracts.

     At December 31, 1998, the Company had entered into forward sales contracts
with two purchasers covering future production of natural gas which expired
during 1999.

10. RESTRUCTURING CHARGES

     During 1998, the Company recorded non-recurring restructuring charges of
$1,869,169 related to severance and related costs resulting from restructuring
of the Company's executive management team, and other personnel changes and
costs associated with the Chapter 11 filing. The components of the restructuring
charges are as follows:

     During 1997 and 1998, the net book value of the Company's oil and natural
gas properties exceeded the full cost ceiling resulting in writedowns of the oil
and natural gas properties of $46.4 million and $148.4 million, respectively.
The Company did not incur ceiling limitation writedowns during 1999. There can
be no assurance that there will not be additional writedowns in future periods
under the full cost method of accounting as a result of sustained decreases in
oil and natural gas prices or other factors.

     Revenues from individual purchasers that exceed 10% of total crude oil and
natural gas sales are as follows:

12. SUPPLEMENTARY CRUDE OIL AND NATURAL GAS RESERVE INFORMATION (UNAUDITED)

     The revenues generated by the Company's operations are highly dependent
upon the prices of, and demand for, oil and natural gas. The price received by
the Company for its oil and natural gas production depends on numerous factors
beyond the Company's control, including seasonality, the condition of the U.S.
economy, foreign imports, political conditions in other oil and natural gas
producing countries, the actions of the Organization of Petroleum Exporting
Countries and domestic governmental regulations, legislation and policies.

     The Company has made, and will continue to make, ordinary course capital
expenditures for the development, and exploitation of oil and natural gas
reserves, subject to economic conditions and in accordance with the rulings and
procedures set forth by the Court. Due to the Chapter 11 filing, the Company has
suspended its development and exploratory drilling program. The Company will
limit its capital expenditures to ordinary course enhancement of current
production through workovers, recompletions, and other production enhancing
activities deemed to be economic. Development drilling is anticipated to be
limited to (i) ordinary course nonoperated wells in which the Company has
limited working interests and in which the failure to participate may result in
drainage, depletion or loss of current reserves and (ii) operated wells deemed
to be economical. Large expenditures for developmental drilling may require
Court approval and none are planned at this time. The Company has interests in
crude oil and natural gas properties that are principally located onshore in
Texas, Louisiana, Oklahoma, Arkansas, and offshore in the Gulf of Mexico. The
Company does not own or lease any crude oil and natural gas properties outside
the United States.

     In 1997 and 1998, estimates of the Company's future net recoverable crude
oil, natural gas, and natural gas liquid reserves were prepared by the Company's
in-house reserve engineers. In 1999, such estimates were prepared by Netherland,
Sewell & Associates, Inc. Estimated proved net recoverable reserves as shown
below include only those quantities that can be expected to be recoverable at
prices and costs in effect at the balance sheet dates under existing regulatory
practices and with conventional equipment and operating methods.

     Proved developed reserves represent only those reserves expected to be
recovered through existing wells. Proved undeveloped reserves include those
reserves expected to be recovered from new wells on undrilled acreage or from
existing wells on which a relatively major expenditure is required for
recompletion.

</TABLE>

     The following is a summary of a standardized measure of discounted net cash
flows related to the Company's proved crude oil and natural gas reserves. For
these calculations, estimated future cash flows from estimated future production
of proved reserves were computed using crude oil and natural gas prices as of
the end of each period presented. Future development, production and abandonment
costs attributable to the proved reserves were estimated assuming that existing
conditions would continue over the economic lives of the individual leases and
costs were not escalated for the future. Estimated future income tax expenses
were calculated by applying future statutory tax rates (based on the current tax
law adjusted for permanent differences and tax credits) to the estimated future
pretax net cash flows related to proved crude oil and natural gas reserves, less
the tax basis of the properties involved and net operating loss carryforwards.

     The Company cautions against using this data to determine the fair value of
its crude oil and natural gas properties. To obtain the best estimate of fair
value of the crude oil and natural gas properties, forecasts of future economic
conditions, varying discount rates, and consideration of other than proved
reserves would have to be incorporated into the calculation. In addition, there
are significant uncertainties inherent in estimating quantities of proved
reserves and in projecting rates of production that impair the usefulness of the
data.

                                 I. INTRODUCTION

         Pursuant to section 1128 of the Bankruptcy Code, the Bankruptcy Court
has scheduled a hearing to consider confirmation of the Plan (the "Confirmation
Hearing"), on May ____, 2000, at ___________ __.m., Central Time, in the United
States Bankruptcy Court for the Northern District of Texas, Dallas Division. The
Bankruptcy Court has directed that objections, if any, to confirmation of the
Plan be filed and served on or before May ____, 2000, in the manner described
under the caption, "Confirmation of the Plan -- Confirmation Hearing" below.

         THE DEBTORS SUPPORT CONFIRMATION OF THE PLAN AND URGE ALL HOLDERS OF
IMPAIRED CLAIMS AND IMPAIRED EQUITY INTERESTS TO ACCEPT THE PLAN.

                         III. EXPLANATION OF CHAPTER 11

A. OVERVIEW OF CHAPTER 11

         Chapter 11 is the principal reorganization chapter of the Bankruptcy
Code. Pursuant to chapter 11, the debtor in possession attempts to reorganize
its business for the benefit of the debtor, its creditors, and other parties in
interest.

         The commencement of a chapter 11 case creates an estate comprising all
the legal and equitable interests of the debtor in property as of the date the
petition is filed. Sections 1101, 1107, and 1108 of the Bankruptcy Code provide
that a debtor may continue to operate its


                                        3
<PAGE>   4


business and remain in possession of its property as a "debtor in possession"
unless the bankruptcy court orders the appointment of a trustee. In the present
Chapter 11 Cases, the Debtors have remained in possession of their properties
and have continued to operate their businesses as debtors in possession.

         The filing of a chapter 11 petition also triggers the automatic stay
provisions of the Bankruptcy Code. Section 362 of the Bankruptcy Code provides,
inter alia, for an automatic stay of all attempts to collect prepetition claims
from the debtor or otherwise interfere with its property or business. Except as
otherwise ordered by the bankruptcy court, the automatic stay remains in full
force and effect until the effective date of a confirmed plan of reorganization.

         The formulation of a plan of reorganization is the principal purpose of
a chapter 11 case. The plan sets forth the means for satisfying the claims
against and interests in the debtor. Generally, unless a trustee is appointed,
only the debtor may file a plan during the first 120 days of a chapter 11 case
(the "Exclusive Period"). However, section 1121(d) of the Bankruptcy Code
permits the court to extend or reduce the Exclusive Period upon a showing of
"cause." After the Exclusive Period has expired, a creditor or any other party
in interest may file a plan, unless the debtor has filed a plan within the
Exclusive Period, in which case, the debtor is generally given 60 additional
days (the "Solicitation Period") during which it may solicit acceptances of its
plan. The Solicitation Period may also be extended or reduced by the court upon
a showing of "cause."

B. PLAN OF REORGANIZATION

         Although referred to as a plan of reorganization, a plan may provide
anything from a complex restructuring of a debtor's business and its related
obligations to a simple liquidation of the debtor's assets. After a plan of
reorganization has been filed, the holders of claims against or interests in a
debtor are permitted to vote to accept or reject the plan. Before soliciting
acceptances of the proposed plan, section 1125 of the Bankruptcy Code requires
the debtor to prepare a disclosure statement containing adequate information of
a kind, and in sufficient detail, to enable a hypothetical reasonable investor
to make an informed judgment about the plan. This Disclosure Statement is
presented to holders of Claims against and Equity Interests in the Debtors to
satisfy the requirements of section 1125 of the Bankruptcy Code.

         If all classes of claims and equity interests accept a plan of
reorganization, the bankruptcy court may nonetheless still not confirm the plan
unless the court independently determines that the requirements of section 1129
of the Bankruptcy Code have been satisfied. Section 1129 sets forth the
requirements for confirmation of a plan and, among other things, requires that a
plan meet the "best interests" test and be "feasible." The "best interests" test
generally requires that the value of the consideration to be distributed to the
holders of claims and equity interests under a plan may not be less than those
parties would receive if the debtor were liquidated pursuant to a hypothetical
liquidation occurring under chapter 7 of the Bankruptcy Code. Under the
"feasibility" requirement, the court generally must find that there is a
reasonable probability that the debtor will be able to meet its obligations
under its plan without the need for further financial reorganization.


                                        4

<PAGE>   5


         The Debtors believe that the Plan satisfies all the applicable
requirements of section 1129(a) of the Bankruptcy Code, including, in
particular, the "best interests of creditors" test and the "feasibility"
requirement. The Debtors support confirmation of the Plan and urge all holders
of impaired Claims and Equity Interests to accept the Plan.

         Chapter 11 does not require that each holder of a claim against or
interest in a debtor vote in favor of a plan of reorganization in order for the
bankruptcy court to confirm the plan. At a minimum, however, the plan must be
accepted by a majority in number and two-thirds in amount of those claims
actually voting in at least one class of impaired claims under the plan. The
Bankruptcy Code also defines acceptance of the plan by a class of equity
interests (equity securities) as acceptance by holders of two-thirds of the
number of shares actually voting. In the present case, only the holders of
Claims or Equity Interests who actually vote will be counted as either accepting
or rejecting the Plan.

         In addition, classes of claims or equity interests that are not
"impaired" under a plan of reorganization are conclusively presumed to have
accepted the plan and thus are not entitled to vote. Accordingly, acceptances of
a plan will generally be solicited only from those persons who hold claims or
equity interests in an impaired class. A class is "impaired" if the legal,
equitable, or contractual rights attaching to the claims or equity interests of
that class are modified in any way under the plan. Modification for purposes of
determining impairment, however, does not include curing defaults and
reinstating maturity or payment in full in cash. ALL CLASSES OF CLAIMS AND
EQUITY INTERESTS ARE IMPAIRED UNDER THE PLAN. CLASS 13 (PREFERRED EQUITY
INTERESTS), CLASS 14 (COMMON EQUITY INTERESTS), AND CLASS 15 (BMC EQUITY
INTERESTS) ARE DEEMED TO HAVE REJECTED THE PLAN AND THEREFORE ARE NOT ENTITLED
TO VOTE ON THE PLAN. ADMINISTRATIVE CLAIMS, PRIORITY TAX CLAIMS, AND INVOLUNTARY
GAP CLAIMS ARE UNCLASSIFIED; THEIR TREATMENT IS PRESCRIBED BY THE BANKRUPTCY
CODE, AND THE HOLDERS OF SUCH CLAIMS ARE NOT ENTITLED TO VOTE ON THE PLAN.
ACCORDINGLY, EACH HOLDER OF A CLAIM (OTHER THAN AN ADMINISTRATIVE CLAIM, A
PRIORITY TAX CLAIM, OR AN INVOLUNTARY GAP CLAIM) IS ENTITLED TO VOTE TO ACCEPT
OR REJECT THE PLAN.

         The bankruptcy court may also confirm a plan of reorganization even
though fewer than all the classes of impaired claims and interests accept it.
For a plan of reorganization to be confirmed despite its rejection by a class of
impaired claims or interests, the proponents of the plan must show, among other
things, that the plan does not "discriminate unfairly" and that the plan is
"fair and equitable" with respect to each impaired class of claims or interests
that has not accepted the plan.

         Under section 1129(b) of the Bankruptcy Code, a plan is "fair and
equitable" as to a class of rejecting claims if, among other things, the plan
provides: (a) with respect to secured claims, that each such holder will receive
or retain on account of its claim property that has a value, as of the effective
date of the plan, equal to the allowed amount of such claim; and (b) with
respect to unsecured claims and equity interests, that the holder of any claim
or equity interest that is junior to the claims or equity interests of such
class will not receive or retain on account of such junior claim or equity
interest any property at all unless the senior class is paid in full.

                                       5
<PAGE>   6


         A plan does not "discriminate unfairly" against a rejecting class of
Claims if (a) the relative value of the recovery of such class under the plan
does not differ materially from that of any class (or classes) of similarly
situated Claims, and (b) no senior class of Claims is to receive more than 100%
of the amount of the Claims in such class.

         The Debtors believe that the Plan has been structured so that it will
satisfy these requirements as to any rejecting Class of Claims or Equity
Interests, and can therefore be confirmed, if necessary, over the objection of
any Classes of Claims or Equity Interests. The Debtors, however, reserve the
right to request confirmation of the Plan under the "cramdown" provisions of
section 1129 of the Bankruptcy Code.

                             IV. SUMMARY OF THE PLAN

A. GENERAL OVERVIEW

         The Plan sets up an efficient and cost-effective mechanism for the
payment of Claims. The Plan provides for (i) continuation of NEG's oil and gas
business operations; (ii) for Secured Claims, including the Amos Secured Claim
in the amount of $25 million, payment in full; (iii) for certain Classes of
claimants involved in litigation with NEG, payment of Cash not to exceed $10,000
if such Class accepts the Plan or, alternatively, if rejected by such Class,
Cash in the amount of 56.5% of any Allowed Claim in such class; (iv) for small
unsecured Claims, payment of Cash equal to 80% of the Allowed Claim; (v) for
Bondholders (excluding Amos), depending on whether the Class of Bondholder
Claims accepts the Plan and subject to the Bankruptcy Court's determination,
either (A) payment of Cash equal to 56.5% of the face value of each Bond or (B)
a pro rata share of the Cash that Bondholders would receive in a liquidation of
the Debtors plus a pro rata beneficial interest in a trust consisting of certain
causes of action, two properties of NEG, and $250,000 in Cash(2); (vi) for trade
creditors, payment of Cash equal to 75% of any Allowed Claim; and (vii)
retention by each of the preferred and common shareholder equity interests in
NEG; provided that both the preferred and common equity interests may, at the
option of Amos, be deemed cancelled and reissued to holders in a form to be
determined by Amos. Neither NEG's preferred shareholders, nor NEG's common
shareholders are entitled to vote on the Plan and have been deemed for all
purposes to have rejected it in its entirety. The Plan further provides that
NEG's existing officers and directors shall continue as the officers and
directors of reorganized NEG until otherwise replaced in accordance with NEG's
bylaws.

         The Debtors believe, and will demonstrate at the Confirmation Hearing,
that confirmation and consummation of the Plan are in the best interests of
creditors and that the Plan will provide maximum return to creditors.



- ----------
(2)  In any event, all Bonds not currently held by Amos will be deemed
     transferred Amos in consideration of the treatment provided to Bondholders
     in the Plan.

B. CLASSIFICATION AND TREATMENT

         The following is a summary of the classification and treatment of
Claims and Equity Interests under the Plan. The Administrative Claims, Priority
Tax Claims, and Involuntary Gap Claims shown below constitute the Debtors'
estimate of the amount of such Claims to be paid in Cash on the Initial
Distribution Date, taking into account amounts paid or projected to be paid
prior to that date. The total amount of Claims shown below reflects the Debtors'
current estimate of the likely amount of such Claims, after the resolution by
settlement or litigation of Claims that the Debtors believe are subject to
disallowance or reduction. Reference should be made to the entire Disclosure
Statement and to the Plan for a complete description of the classification and
treatment of Claims and Equity Interests.

         THIS IS ONLY A SUMMARY OF CERTAIN PROVISIONS OF THE PLAN. THE PLAN
INCLUDES OTHER PROVISIONS THAT MAY AFFECT YOUR RIGHTS. YOU ARE URGED TO READ THE
PLAN IN ITS ENTIRETY BEFORE VOTING ON THE PLAN.


         1. UNCLASSIFIED CLAIMS AGAINST THE DEBTORS

         Unclassified Claims against the Debtors consist of Administrative
Claims, Priority Tax Claims, and Involuntary Gap Claims in accordance with
section 1123(a)(1) of the Bankruptcy Code. Based on their books and records and
their projections for future expenses, the Debtors presently estimate the
amounts of such Claims as follows:

<TABLE>
<S>                                                   <C>
                    Administrative Claims             $6,600,000
                    Priority Tax Claims               $  500,000
                    Involuntary Gap Claims            $1,750,000
</TABLE>

         The above estimate of Administrative Claims consists of the following:

<S>                                                   <C>
                    Post-Petition Trade Claims        $2,250,000

                    Miscellaneous                        100,000
</TABLE>


         All professional fees and expenses are subject to review and approval
by the Bankruptcy Court pursuant to section 330 of the Bankruptcy Code.

(ii) a liability incurred and paid in the ordinary course of business by the
Debtors, or (iii) an Allowed Administrative Claim, must file with the Bankruptcy
Court, and serve on the Debtors and their counsel, notice of such Administrative
Claim within thirty (30) days after the Effective Date. Such notice must include

Failure to file timely and properly the notice required under section 2.1(a) of
the Plan shall result in the Administrative Claim being forever barred and
discharged.

         Each Professional who holds, or asserts, an Administrative Claim that
is a Fee Claim for compensation for services rendered and reimbursement of
expenses incurred prior to the Effective Date shall be required to file with the
Bankruptcy Court and serve on all parties required to receive such notice, a Fee
Application within sixty (60) days of the Effective Date. Failure to file timely
a Fee Application as required under section 2.1(b) of the Plan shall result in
the Fee Claim being forever barred and discharged.

         An Administrative Claim with respect to which notice has been properly
filed pursuant to section 2.1(a) of the Plan shall become an Allowed
Administrative Claim if no objection is filed within thirty (30) days after its
filing and service. If an objection is filed within such thirty (30) day period,
the Administrative Claim shall become an Allowed Administrative Claim only to
the extent Allowed by Final Order. An Administrative Claim that is a Fee Claim,
and with respect to which a Fee Application has been properly filed pursuant to
section 2.1(b) of the Plan, shall become an Allowed Administrative Claim only to
the extent allowed by Final Order of the Bankruptcy Court.

         Each holder of an Allowed Administrative Claim shall receive the amount
of such holder's Allowed Administrative Claim in Cash on or before the Initial
Distribution Date, or shall receive such other treatment as agreed upon in
writing by the Debtors and such holder; provided, however, that an
Administrative Claim representing a liability incurred in the ordinary course of
business by the Debtors may be paid in the ordinary course of business by the
Debtors; and provided, further, that the payment of an Allowed Administrative
Claim representing a right to payment under sections 365(b)(1)(A) and
365(b)(1)(B) of the Bankruptcy Code may be made in one or more Cash payments
over a period of eighteen (18) months or such other period as is determined to
be appropriate by the Bankruptcy Court.

         Each holder of an Allowed Priority Tax Claim shall receive, at the
option of the Reorganized Debtor, (i) the full amount of such holder's Allowed
Claim in one Cash payment on or before the Initial Distribution Date; (ii) the
amount of such holder's Allowed Claim, with interest accruing after the
Confirmation Date thereon, in equal quarterly Cash payments of principal and
interest at 7% per annum commencing on July 1, 2000, and continuing to that the
entire Allowed Priority Tax Claim is satisfied in full on or prior to the sixth
(6th) anniversary of the date of assessment of such Claim; or (iii) such other
treatment as may be agreed upon in writing by the Reorganized Debtor and such
holder.

         Each holder of an Allowed Involuntary Gap Claim shall receive the full
amount of such Allowed Involuntary Gap Claim in one Cash payment on or before

C. MEANS OF IMPLEMENTATION OF THE PLAN

         1. DISTRIBUTIONS

         The Reorganized Debtor shall make all distributions from Cash on hand
to holders of Allowed Claims, other than the distributions to be made to holders
of Allowed Non-Arnos Bondholder Claims. Distributions to holders of Allowed
Bondholder Claims will be made as follows:


                                       15
<PAGE>   16

                  (i) Cash Package. If Class 10 accepts the Plan (or if Class 10
         rejects the Plan and the Bankruptcy Court determines that the 56.5%
         Cash option is in the better interests of holders of Non-Arnos
         Bondholder Claims), Arnos shall deliver to the Exchange Agent, within
         five (5) business days after the Effective Date, a portion of the
         Escrowed Funds equal to 56.5% of the aggregate principal amount of the
         Non-Arnos Bondholder Claims for distribution to holders of such Claims
         in accordance with Article 4.11(b)(i) of the Plan. Arnos shall retain
         the remainder of the Escrowed Funds.

                  (ii) Liquidation/Creditors' Trust Package. If Class 10 does
         not accept the Plan and the Bankruptcy Court determines that the
         combination of the liquidation-amount recovery and the Creditors' Trust
         is in the better interests of holders of Non-Arnos Bondholder Claims,
         within five (5) business days after the Effective Date, (i) Arnos shall
         deliver to the Exchange Agent a portion of the Escrowed Funds equal to
         the Non-Arnos Bondholder Recovery Percentage of the aggregate principal
         amount of the Non-Arnos Bondholder Claims, and (ii) NEG shall transfer
         all of the Creditors' Trust Assets to the Creditors' Trust. Arnos shall
         retain the remainder of the Escrowed Funds.

         2. EXCHANGE AGENT

         The Exchange Agent shall have the powers, duties and obligations
specified in the Plan and in the Exchange Agent Agreement, which will be filed
no fewer than fifteen (15) days prior to the Confirmation Hearing. The liability
of the Exchange Agent will be limited so that he shall not be liable for his
actions in connection with his performance of his obligations under this Plan
unless he has been guilty of willful fraud or gross negligence. The Exchange
Agent shall not be required to give a bond for the faithful performance of his
duties hereunder.

         3. CREDITORS' TRUST

         Generally. If Class 10 does not accept the Plan and the Bankruptcy
Court determines that the combination of the liquidation-amount recovery and the
Creditors' Trust is in the better interests of holders of Non-Arnos Bondholder
Claims, the Creditors' Trust shall be established as of the Effective Date by
execution of the Creditors' Trust Agreement and the transfer of the Creditors'
Trust Assets to the Creditors' Trustee pursuant to the terms and conditions
thereof.

         Creditors' Trust Assets. The Creditors' Trust Assets consist of all of
the Debtors' and their Estates' right, title, and interest in and to the
following assets: (i) Avoidance Actions, defined as any action arising in the
Chapter 11 Cases for avoidance and recovery of obligations, transfers of
property or interests in property pursuant to sections 544, 545, 547, 548, 550
and/or 551 of the Bankruptcy Code, subject to the limitation set forth in
section 13.1 of the Plan; plus the Transferred Causes of Action, defined as all
causes of action held by the Debtors as of the Petition Date and which are
unrelated to the operating assets retained by the Reorganized Debtor pursuant to
the Plan; (ii) the Lake Mongoulois Property; (iii) the Mustang Island Property,
and (iv) Cash in the amount of $250,000.

         Lake Mongoulois Property. The Lake Mongoulois Property consists of
NEG's 50% working interest in the Lake Mongoulois Field in St. Martin Parish,
Louisiana, which working

                                       16
<PAGE>   17

interest NEG acquired from EEX Corporation ("EEX") in February 1998. The LMU #17
has been the lone producing well that has held the unit, although the LMU #17
has not produced in the past several months. When the well has produced, it has
been capable of producing one day a month for +/- 10 barrels of oil after an
extended shut-in period. NEG operates the field with existing personnel out of
the Bayou Sorrel Area. Texaco discovered the Lake Mongoulois Field in 1938 and
by the late 1950s had drilled 71 wells, of which 47 were productive and 24 were
plugged and abandoned as dry holes. Peak production for the field averaged 1,870
Bopd and 5,900 Mcf/d. Cumulative production for the field is +/- 20 Mmbo and +/-
62 Bcf of gas. Ten Miocene and ten Oligocene sands (2100' to 12,000') have
produced around the faulted salt dome structure, with the majority of the
production coming from the Marg. Vag. and Cib. Haz. sands. NEG has projected a
$1.9 million net plugging and abandonment liability ($1.7 million negative PV-10
value). Netherland, Sewell & Associates, Inc., a leading petroleum engineering
and geologic consulting firm, concurred with this estimate for purposes of
preparing its reserve report for NEG. NEG has solicited nonbinding bids from
several third-party contractors and the average of those bids, net to NEG, has
been approximately $3.4 million.

         Mustang Island Property. The Mustang Island Property consists of NEG's
various interests in leases, wells, and equipment in the Mustang Island area in
Nueces County, Texas. NEG acquired these interests between 1994 and 1998 from
LLOG, Petrotex Engineering, UMC Petroleum, Germany Oil, and the State of Texas.
Offshore equipment consists of three monopods and two platforms with nine
wells. Two wells are active, the SL904 GU #1 and 773-L (NW/4) #1. The 773-L #1
produces only one day a month for leasehold purposes, although NEG has also paid
shut-in royalties under the lease. Another well, the ST 901 #2, became loaded
with water and went offline effective as of February 5, 2000. The current
respective rates of the SL 904 GU #1 are 640 Mcf/d, 42 Bopd and 210 Bwpd at
2,700 psig FTP and 45 Bopd, 105 Mcf/d and 640 Bwpd at 450 psig FTP. Produced
waste is disposed offshore via separation at the platform. Oil and gas are
transported through NEG pipelines to a shore facility located on Mustang Island.
Additional processing equipment and storage tanks are located at this site and
allow for the trucking of crude oil. Gas is transported through an NEG pipeline
that crosses the Laguna Madre into a gas plant facility located in the Flour
Bluff community. Custody transfer of the gas occurs at the sales meter located
on plant property. NEG has projected a $3.5 million net plugging and abandonment
liability. Netherland, Sewell & Associates, Inc. has concurred with this
estimate for purposes of preparing its reserve report. The City of Corpus
Christi requires storm choke inspections on wellbores every two years, and the
inspection on the NEG properties is due before the end of 1999.

         4. REVESTING OF ASSETS

         Except as otherwise provided in the Plan or the Confirmation Order,
upon the Effective Date, all property of the Debtors' Estates, wherever
situated, shall vest in, or remain the property of, the Reorganized Debtor free
and clear of all Claims. All causes of action of the Debtors' Estates, including
all Avoidance Actions, shall be preserved and vest in the Reorganized Debtor;
provided, however, that if Class 10 does not accept the Plan and the Bankruptcy
Court confirms the Plan in accordance with Article 4.11(b)(ii)(B) thereof, all
of the Transferred Causes of Action shall be transferred to the Creditors'
Trust.


                                       17
<PAGE>   18


         5. DISCHARGE OF DEBTORS

         Except as otherwise provided in the Plan, all consideration distributed
under the Plan shall be in exchange for, and in complete satisfaction,
discharge, and release of, all Claims of any nature whatsoever against the
Debtors or any of their assets or properties; and except as otherwise provided
herein, upon the Effective Date, the Debtors and their successors in interest
shall be deemed discharged and released pursuant to section 1141(d)(1)(A) of
the Bankruptcy Code from any and all Claims treated in the Plan, as well as all
other Claims, demands and liabilities that arose before the Effective Date, and
all debts of the kind specified in section 502(g), 502(h), or 502(i) of the
Bankruptcy Code, whether or not (a) a proof of Claim based upon such debt is
filed or deemed filed under section 501 of the Bankruptcy Code; (b) a Claim
based upon such debt is Allowed under section 502 of the Bankruptcy Code; (c)
the holder of a Claim based upon such debt has accepted this Plan; or (d) the
Claim has been Allowed, disallowed, or estimated pursuant to section 502(c) of
the Bankruptcy Code. Except as otherwise provided in the Plan, the Confirmation
Order shall be a judicial determination of discharge of all liabilities of the
Debtors and their successors in interest other than those obligations
specifically set forth pursuant to this Plan.

         6. INJUNCTION

         Except as otherwise provided in the Plan, from and after the
Confirmation Date, all holders of Claims against and Equity Interests in the
Debtors are permanently restrained and enjoined (a) from commencing or
continuing in any manner, any action or other proceeding of any kind with
respect to any such Claim or Equity Interest against the Debtors, their Assets,
or the Reorganized Debtor or against their financial advisors or attorneys; (b)
from enforcing, attaching, collecting, or recovering by any manner or means, any
judgment, award, decree, or order against the Reorganized Debtor, its Assets,
the Debtors, the Committee or against their financial advisors or attorneys; (c)
from creating, perfecting, or enforcing any encumbrance of any kind against the
Reorganized Debtor, its Assets, the Debtors or the Committee or against their
financial advisors or attorneys; (d) from asserting any setoff, right of
subrogation, or recoupment of any kind against any obligation due the Debtors;
and (e) from performing any act, in any manner, in any place whatsoever, that
does not conform to or comply with the provisions of the Plan; provided,
however, that each holder of a Contested Claim may continue to prosecute its
proof of Claim in the Bankruptcy Court and all holders of Claims and Equity
Interests shall be entitled to enforce their rights under the Plan and any
agreements executed or delivered pursuant to or in connection with the Plan.

         7. REVOCATION OF PLAN

         The Debtors reserve the right to revoke and withdraw the Plan before
the entry of the Confirmation Order. If the Debtors revoke or withdraw this
Plan, or if confirmation of this Plan does not occur, then, with respect to the
Debtors, this Plan shall be deemed null and void and nothing contained herein
shall be deemed to constitute a waiver or release of any Claims by or against
the Debtors, as the case may be, or any other Person or to prejudice in any
manner the

                                       19
<PAGE>   20


to 49.9% of the value of all issued and outstanding common and preferred stock
of the Reorganized Debtor.

D. EXECUTORY CONTRACTS AND UNEXPIRED LEASES

         1. GENERAL TREATMENT; ASSUMED IF NOT REJECTED

         The Plan constitutes and incorporates a motion by the Debtors to
assume, as of the Effective Date, all prepetition executory contracts and
unexpired leases to which the Debtors are a party, except for executory
contracts or unexpired leases that (a) have been assumed or rejected pursuant to
Final Order of the Bankruptcy Court, (b) are the subject of a separate motion
pursuant to section 365 of the Bankruptcy Code to be filed and served by the
Debtors on or before the Confirmation Date, or (c) are designated on Exhibit "2"
of the Plan as executory contracts and unexpired leases which the Debtors intend
to reject.

         2. CURE PAYMENTS AND RELEASE OF LIABILITY

         All cure payments which may be required by section 365(b)(1) of the
Bankruptcy Code under any executory contract or unexpired lease that is assumed,
or assumed and assigned, under this Plan shall be made on or before the Initial
Distribution Date; provided, however, that in the event of a dispute regarding
the amount of any cure payments, the cure of any other defaults, the ability of
any party to provide adequate assurance of future performance, or any other
matter pertaining to assumption or assignment, the Reorganized Debtor shall make
such cure payments and cure such other defaults and provide adequate assurance
of future performance, all as may be required by section 365(b)(l), of the
Bankruptcy Code only following the entry of a Final Order resolving such
dispute. To the extent that a party to an assumed executory contract or
unexpired lease has not filed an appropriate pleading with the Bankruptcy Court
on or before the thirtieth (30th) day after the Effective Date disputing the
amount of any cure payments offered to it, disputing the cure of any other
defaults, disputing the promptness of the cure payments, or disputing the
provisions of adequate assurance of future performance, then such party shall be
deemed to have waived its right to dispute such matters.

         3. BAR TO REJECTION DAMAGES

         If the rejection of an executory contract or an unexpired lease by the
Debtors results in damages to the other party or parties to such contract or
lease, a Claim for such damages shall be forever barred and shall not be
enforceable against the Debtors or their respective properties or agents,
successors, or assigns, unless a proof of Claim is filed with the Bankruptcy
Court and served upon the Reorganized Debtor by the earlier of (a) 30 days after
the Confirmation Date or (b) such other deadline as the Bankruptcy Court may set
for asserting a Claim for such damages.

         4. REJECTION CLAIMS

         Any Claim arising from the rejection of an unexpired lease or executory
contract and not barred by section 10.3 of the Plan shall be treated as a Trade
Claim pursuant to the Plan; provided, however, that any Claim based upon the
rejection of an unexpired lease of real

                                       20

<PAGE>   21

property shall be limited in accordance with section 502(b)(6) of the Bankruptcy
Code and state law mitigation requirements. Nothing contained herein shall be
deemed an admission by the Debtors that such rejection gives rise to or results
in a Claim or shall be deemed a waiver by the Debtors of any objections to such
Claim if asserted.

         In connection with the Lake Mongoulois Property, discussed above, NEG
entered into a Participation Agreement with EEX on January 13, 1998. Pursuant to
the Participation Agreement, EEX assigned to NEG an undivided 50% interest in
EEX's right, title, and interest in and to certain oil and gas properties in St.
Martin Parish, Louisiana. In addition, NEG agreed to spend a total of $7.0
million for its account and for the account of EEX for operations to drill,
complete, deepen, rework, and recomplete wells (or, if dry holes, to plug and
abandon such wells and restore the surface locations) within the Lake Mongoulois
area, by December 31, 1999. NEG also agreed to assume 50% of the plugging and
abandonment ("P&A") liability. NEG is advised that its P&A liability under the
Participation Agreement will be approximately $3.4 million. NEG intends to
reject the Participation Agreement as an executory contract. Following
rejection, however, EEX will be entitled to assert an unsecured prepetition
Claim against NEG's Estate for any damages arising as a result of the rejection
or otherwise under the Participation Agreement, including the unsatisfied
development obligation and the unpaid P&A liability.


                          V. DESCRIPTION OF THE DEBTORS

A. OVERVIEW

         NEG was incorporated under the laws of the State of Delaware on
November 20, 1990. Effective June 11, 1991, Big Piney Oil and Gas Company and VP
Oil, Inc. merged with and into NEG. On August 29, 1996, Alexander Energy
Corporation was merged with and into a wholly owned subsidiary of NEG, which
subsidiary was merged with and into NEG on December 31, 1996.

         NEG is an independent energy company which has historically engaged in
the exploration, acquisition, exploitation, development and operation of oil and
natural gas properties in major producing basins onshore in Texas, Louisiana,
Oklahoma, Arkansas, and Mississippi, and offshore in the Gulf of Mexico.

B. BUSINESS OF THE DEBTORS

         1. PRINCIPAL AREAS OF OPERATIONS

         Due to the chapter 11 filing, NEG has suspended its exploratory and
development drilling program. However, NEG currently has an inventory of
exploratory prospects in Louisiana and offshore at Mustang Island.

         Historically, NEG has developed and exploited existing properties by
drilling Development Wells, and recompleting and reworking existing wells. NEG
will continue to

                                       21
<PAGE>   22

participate in non-operated wells as described above and continue its drilling
operations where economical in accordance with the rulings and procedures set
forth by the Bankruptcy Court.

         The following table sets forth NEG's principal areas of operations and
NEG's Proved Reserves of oil and natural gas at December 31, 1999. See -- "Oil

                            ======     ======     ======      =====
</TABLE>

                  (a) Mid-Continent area

         At December 31, 1999, approximately 37.5% (36.2 Bcfe) of NEG's Proved
Reserves were located in the Mid-Continent area in Oklahoma and Western
Arkansas, which includes the Anadarko and Arkoma Basins.

ANADARKO BASIN. The Anadarko Basin is considered a mature oil and natural gas
province characterized by multiple producing horizons and relatively long
reserve lives. Drilling a Producing Well on these locations can convert Proved
Undeveloped Reserves to Proved Developed Producing Reserves, and can provide
additional PUD locations on NEG's leasehold acreage.

         NEG's Anadarko Basin properties were initially drilled on 640-acre
producing units. Industry has successfully demonstrated to Oklahoma regulators
that deeper wells in the Anadarko Basin will not efficiently drain 640 acres and
have obtained authorization for increased density drilling on smaller acreage
units. Further, under the forced pooling rules in Oklahoma, even if NEG is not
the operator of the property for which increased density drilling has been
approved, NEG may propose to drill and operate additional wells on the original
production unit. Frequently this results in the proposing party owning a larger
portion of newly drilled wells because other Working Interest owners may decline
to participate.


                                       22
<PAGE>   23


         During the year ended December 31, 1999, NEG drilled 3 Gross (.38 Net)
Development Wells in the Anadarko Basin, of which 3 Gross (.38 Net) Development
Wells were completed as commercially productive. NEG's wells typically are
completed in horizons ranging in depth between 7,000 and 15,000 feet.

ARKOMA BASIN. Most Arkoma Basin reserves are produced from formations at depths
ranging from approximately 3,000 to 8,000 feet.

         During 1999, NEG drilled 2 Gross (.64 Net) Development Wells in the
Arkoma Basin of which 1 Gross (.48 Net) Development Well was completed as
commercially productive. The typical Arkoma Basin well is drilled to a total
depth of approximately 7,500 feet.

                  (b) East and West Texas Area

         At December 31, 1999, approximately 40.6% (39.2 Bcfe) of NEG's Proved
Reserves were located in the East and West Texas area, including East Texas and
the Goldsmith Adobe Unit in West Texas.

EAST TEXAS. These reserves are found in the Cotton Valley formation and the
Travis Peak formation. The Cotton Valley formation is generally found at depths
of 8,500 to 10,500 feet in NEG's area of interest. These properties produce from
low permeability reservoirs that generally contain relatively long life natural
gas reserves. A significant portion of the cost to complete Cotton Valley wells
is incurred due to the low permeability of interbedded sandstones and shales,
which requires large hydraulic fracture stimulation, typically of multiple zones
of the producing formation, to obtain the increased production levels necessary
to make such wells commercially viable. The Travis Peak formation is generally
found at a depth of 7,200 feet and principally contains oil reserves.

         During the year ended December 31, 1999, NEG did not drill any wells in
the East and West Texas Areas.

GOLDSMITH ADOBE UNIT ("GAU"). The Goldsmith Adobe Unit is in the Permian Basin
in West Texas. NEG owns approximately a 95% Working Interest in the GAU, which
it operates.

         Originally the GAU was drilled on 40 acre spacing units. Previous
operators had drilled several wells on 20 acre spacing units and, based on the
results of this drilling and 20 acre spacing development on adjoining leases,
NEG began a drilling program in July 1994 to develop the GAU on 20 acre spacing
units. Typically, wells drilled by NEG at the GAU are drilled to depths between
5,600 and 6,000 feet into the Clearfork formation. During 1999, NEG did not
drill any wells at the GAU.

                  (c) Gulf Coast Area

         At December 31, 1999, 21.9% (21.1 Bcfe) of NEG's Proved Reserves were
located in the Gulf Coast areas, principally in the Greater Bayou Sorrel Area in
Iberville Parish, Louisiana and


                                       23
<PAGE>   24


at Mustang Island in offshore Gulf of Mexico. NEG also has participated in
exploratory activity in various parishes throughout Southern Louisiana.

GREATER BAYOU SORREL AREA. The Greater Bayou Sorrel Area is located
approximately eighty miles west of New Orleans, in Iberville Parish, Louisiana,
in the Atchafalaya River Basin. The target formations of NEG's exploration
prospects in this area range from approximately 11,000 to 14,000 feet and
include the Marg Vag, Marg Howeii, Camerina, Cib Haz, and Marg Tex zones. The
topography of the surface is river swamp and all work must be done with
barge-mounted drilling rigs and boats. Production platforms are mounted on
pilings. NEG first participated in the successful exploratory test of the
Schwing #1 well in NEG's East Bayou Sorrel prospect in January 1996. This
discovery well was drilled to a total depth of approximately 14,000 feet on the
eastern flank of the old Bayou Sorrel Field, which was discovered by Shell Oil
Company in 1954. The old Bayou Sorrel Field was drilled in the 1950s and 1960s,
with a total of 87 wells drilled and produced in twenty-eight different horizons
ranging in depths from 7,000 to 11,100 feet. During 1997, NEG successfully
drilled and completed a second test well, the Schwing #2. In 1998, NEG added a
third producing well to the East Bayou Sorrel Field, the #1 State Lease 2102.

         During 1999, NEG did not drill any wells in the Greater Bayou Sorrel
Area.

         NEG has completed shooting, processing and interpreting, an approximate
54 square mile 3-D seismic survey over the Greater Bayou Sorrel Area. NEG has
identified additional potential drilling locations for prospects in this area
through interpretation of the 3-D seismic data. The Greater Bayou Sorrel Area
has produced and continues to produce significant oil and gas. Because of the
difficult topography, very little seismic data had been acquired prior to NEG's
3-D survey. NEG controls approximately 13,400 acres either by lease or option
to lease, within the Greater Bayou Sorrel Area.

         In March 1998, NEG acquired Fortune Natural Resources Corporation's
interests in the East Bayou Sorrel field for approximately $4.5 million in cash.

MUSTANG ISLAND. The Mustang Island area is located offshore in shallow state
waters in Nueces County, Texas. NEG currently has approximately a 92% working
interest in approximately 16,000 gross acres of leases, majority interests in 2
producing wells, 11 miles of pipeline, and an onshore tank facility. In
addition, NEG participated in a 3-D seismic survey over the area, which provided
approximately 90 square miles of data. Three exploratory opportunities have been
identified from this 3-D seismic data. NEG did not drill any wells at Mustang
Island during 1999.

         In June 1998, NEG acquired Germany Oil Company's interest in six state
leases and one producing well in the Mustang Island area for $.4 million in
cash.

OTHER SOUTH LOUISIANA. NEG has also participated in exploratory prospects
outside of the Greater Bayou Sorrel area in various parishes in South Louisiana.
During 1999, NEG did not drill any wells in these areas.

         2. OIL AND NATURAL GAS RESERVES

         The estimated reserves and related future net revenues as of December
31, 1999, were prepared by independent outside petroleum engineers. All of NEG's
reserves are located in the continental United States. Each of the This reserve
reports was prepared using constant prices and costs in accordance with the
published guidelines of the SEC. The net weighted average prices used in NEG's
reserve report at December 31, 1999, were $24.97 per barrel of oil and $2.26 per
Mcf of natural gas. The estimation of reserves and future net revenues can be
materially affected by the oil and gas prices used in preparing the reserve
report. Substantially all of NEG's oil and natural gas properties are subject to
liens, and the remaining oil and natural gas properties are subject to a
negative pledge pursuant to NEG's credit facility.

         All reserves are evaluated at constant temperature and pressure, which
can affect the measurement of natural gas reserves. Estimated operating costs,
development costs, abandonment costs and certain production-related and ad
valorem taxes were deducted in arriving at the estimated future net cash flows.
No provision was made for income taxes. The following estimates set forth
reserves considered to be economically recoverable under normal operating
methods and existing conditions at the prices and operating costs prevailing at
the dates indicated above. The estimates of the PV10% from future net cash flows
can differ from the Standardized Measure of discounted future net cash flows set
forth in the notes to the Financial Statements of NEG, which is calculated after
provision for future income taxes. There can be no assurance that these
estimates are accurate predictions of future net cash flows from oil and natural
gas reserves or their present value.

         Reservoir engineering is a subjective process of estimating the
volumes of underground accumulations of oil and natural gas that cannot be
measured in an exact way. The accuracy of any reserve estimates is a function of
the quality of available data and of engineering and geological interpretation
and judgment. Reserve estimates prepared by other engineers might differ from
the estimates contained herein. Results of drilling, testing, and production
subsequent to the date of the estimate may justify revision of such estimate.
Future prices received for the sale of oil and natural gas may be different from
those used in preparing these reports. The amounts and timing of future
operating and development costs may also differ from those used. Accordingly,
reserve estimates are often different from the quantities of oil and natural gas
that are ultimately recovered.

         No estimates of Proved Reserves of oil and natural gas have been filed
by NEG with, or included in any report to, any United States authority or agency
(other than the SEC) since December 31, 1998.

         The following table sets forth certain information for NEG's total
Proved Reserves of oil and natural gas and the PV 10% of estimated future net
revenues from such reserves, at December 31, 1999.

</TABLE>


         NEG generally acquires a leasehold interest in the properties to be
explored. The leases grant the lessee the right to explore for and extract oil
and natural gas from a specified area. Lease rentals usually consist of a fixed
annual charge made prior to obtaining production. Once production has been
established, a royalty is paid to the lessor based upon the gross proceeds from
the sale of oil and natural gas. Once wells are drilled, a lease generally
continues as long as

                                       26

<PAGE>   27

production of oil and natural gas continues. In some cases, leases may be
acquired in exchange for a commitment to drill or finance the drilling of a
specified number of wells to predetermined depths.

         Substantially all of NEG's producing oil and natural gas properties are
located on leases held by NEG for an indeterminate number of years as long as
production is maintained. All of NEG's non-producing acreage is held under
leases from mineral owners or a government entity which expire at varying dates.
NEG is obligated to pay annual delay rentals to the lessors of certain
properties in order to prevent the leases from terminating. Delay rentals were
approximately $.9 million for the year ended December 31, 1998 and were
approximately $.6 million for the year ended December 31, 1999, and could
increase in future periods depending on NEG's lease acquisition activities.

         5. TITLE TO OIL AND NATURAL GAS PROPERTIES

         NEG has acquired interests in producing wells and undeveloped acreage
in the form of Working Interests, Royalty Interests, and Overriding Royalty
Interests. To reduce NEG's financial exposure in any one exploratory prospect,
NEG often acquires less than 100% of the Working Interest in a prospect. Working
Interests held by NEG may, from time to time, become subject to minor liens.
Prior to an acquisition, due diligence investigations are made in accordance
with standard practices in the industry, which may include securing an
acquisition title opinion.

         6. PRODUCTION AND SALES PRICES

         NEG produces oil and natural gas solely in the continental United
States. NEG has no obligations to provide a fixed and determinable quantity of
oil and/or natural gas in the future under existing contracts or agreements. Nor
does NEG refine or process the oil and natural gas it produces, but sells the
production to unaffiliated oil and natural gas purchasing companies in the area
in which it is produced. NEG expects to sell crude oil on a market price basis
and to sell natural gas under contracts to both interstate and intrastate
natural gas pipeline companies. NEG currently sells a significant portion of oil
pursuant to a contract with Plains Marketing and Transportation. See "-- Markets
and Customers."

         7. CONTROL OVER PRODUCTION ACTIVITIES

         The non-operated properties are operated by unrelated third parties
pursuant to operating agreements that are generally standard in the industry.
Significant decisions about operations regarding non-operated properties may be
determined by the outside operator rather than by NEG. If NEG declines to
participate in additional activities proposed by the outside operator under
certain operating agreements, NEG will not receive revenues from, and/or will
lose its interest in the activity in which it declined to participate.


                                       27
<PAGE>   28


         8. MARKETS AND CUSTOMERS

         The availability of a ready market for any oil and natural gas produced
by NEG and the prices obtained for such oil and natural gas depend upon numerous
factors beyond its control, including the demand for and supply of oil and
natural gas; fluctuations in production and seasonal demand; the availability of
adequate pipeline and other transportation facilities; weather conditions;
economic conditions; imports of crude oil; production by and agreements among
OPEC members; and the effects of state and federal governmental regulations on
the import, production, transportation, sale and taxation of oil and natural
gas. The occurrence of any factor that affects a ready market for NEG's oil and
natural gas or reduces the price obtained for such oil and natural gas, may
adversely affect NEG.

         A large percentage of NEG's oil and natural gas sales are made to a
small number of purchasers. NEG normally sells its oil under six month
contracts. For the year ended December 31, 1997, Plains Marketing and
Transportation ("Plains") accounted, for 84% of NEG's oil sales, and Crosstex
Energy ("Crosstex") and GPM Natural Gas Corporation accounted for 20% and 14%,
respectively, of NEG's natural gas sales. For the year ended December 31, 1998,
Plains accounted for 85% of NEG's oil sales, and Crosstex and Aquila Energy
Marketing ("Aquila") accounted for 23% and 26%, respectively, of NEG's natural
gas sales. For the year ended December 31, 1999, Plains accounted for 90% of
NEG's oil sales, and Crosstex and Aquila accounted for 21% and 17%,
respectively, of NEG's natural gas sales. The agreement with Plains, entered
into in 1993, provides for Plains to purchase NEG's oil pursuant to West Texas
Intermediate posted prices plus a premium. NEG does not believe that the loss of
any purchaser would have a material adverse effect on its business because,
under prevailing market conditions, such purchaser could be replaced.

         A portion of NEG's natural gas production is sold pursuant to long-term
netback contracts. Under netback contracts, gas purchasers buy gas from a number
of producers, process the gas for natural gas liquids, and sell the liquids and
residue gas. Each producer receives a fixed portion of the proceeds from the
sale of the liquids, and residue gas. The gas purchasers pay for transportation,
processing, and marketing of the gas and liquids, and assume the risk of
contracting pipelines and processing plants in return for a portion of the
proceeds of the sale of the gas and liquids. Generally, because the purchasers
are marketing large volumes of hydrocarbons gathered from multiple producers,
higher prices may be obtained for the gas and liquids. A portion of NEG's
natural gas production is also sold under forward sales contracts. See Note 9 of
Notes to Consolidated Financial Statements, attached hereto as EXHIBIT B.
Deliveries under these contracts are priced based on NYMEX prices less a
differential whereby NEG may fix the price for deliveries under these contracts
at any time three days prior to the close of the then current contract based on
the NYMEX prices at that time. NEG pays the cost of transportation of the
natural gas to the delivery point specified in these contracts. The remainder of
NEG's natural gas is sold on the spot market under short-term contracts.

         9. REGULATION

GENERAL. NEG's oil and natural gas exploration, production, and related
operations are subject to extensive rules and regulations promulgated by federal
and state agencies. Failure to comply with such rules and regulations can result
in substantial penalties. The regulatory burden on the oil and gas industry
increases NEG's cost of doing business and affects its profitability. Because
such rules and regulations are frequently amended or interpreted by federal and
state agencies or jurisdictions, NEG is unable to predict the future cost or
impact of complying with such laws.

EXPLORATION AND PRODUCTION. NEG's exploration and development operations are
subject to various types of regulation at the federal, state, and local levels.
Such regulation includes requiring permits for the drilling of wells;
maintaining bonding requirements in order to drill or operate wells; and
regulating the location of wells, the method of drilling and casing wells, the
surface use and restoration of properties upon which wells are drilled, and the
plugging and abandoning of wells. NEG's operations are also subject to various
conservation regulations and rules to protect the correlative rights of mineral
interest owners. These include the regulation of the size of drilling and
spacing units or proration units, the density of wells that may be drilled, and
the unitization or pooling of oil and natural gas properties. In this regard,
some states allow the forced pooling or integration of tracts to facilitate
exploration, while other states rely on voluntary pooling of land and leases. In
addition, some state conservation laws establish maximum rates of production
from oil and natural gas wells, generally prohibit the venting or flaring of
natural gas, and impose certain requirements regarding the ratability of
production. The effect of these regulations is to limit the amounts of oil and
natural gas NEG can produce from its wells and to limit the number of wells or
the locations at which NEG can drill. Legislation in Oklahoma and regulatory
action in Texas governs the methodology by which the regulatory agencies
establish permissible monthly production allowables. NEG cannot predict what
effect any change in prorationing regulations might have on its production and
sales of natural gas.

         Certain of NEG's Oil, Gas and Mineral Leases are granted by the federal
government and administered by various federal agencies. Such leases require
compliance with detailed federal regulations and orders which regulate, among
other matters, drilling and operations on these leases and calculation and
disbursement of royalty payments to the federal government. The Mineral Lands
Leasing Act of 1920 places limitations on the number of acres under federal
leases that may be owned in any one state.

ENVIRONMENTAL PROTECTION AND OCCUPATIONAL SAFETY. NEG is subject to numerous
federal, state and local laws and regulations governing the release of materials
into the environment or otherwise relating to environmental protection. These
laws and regulations may require the acquisition of a permit before drilling
commences, restrict the types, quantities and concentration of various
substances that can be released into the environment in connection with drilling
and production activities, limit or prohibit drilling activities on certain
lands lying within wilderness, wetlands and other protected areas, and impose
substantial liabilities for pollution resulting from operations. Moreover, the
recent trend toward stricter standards in environmental legislation and
regulation is likely to continue. For instance, legislation has been proposed in
Congress from

                                       29

<PAGE>   30


time to time that would reclassify certain oil and natural gas production wastes
as "hazardous wastes," which reclassification would make such wastes subject to
much more stringent handling, disposal, and clean-up requirements. If such
legislation were to be enacted, it could have a significant impact on the
operating costs of NEG, as well as the oil and gas industry in general. It is
not anticipated that NEG will be required in the near future to expend amounts
that are material in relation to its total capital expenditure program by reason
of environmental laws and regulations, but because such laws and regulations
are frequently changed, NEG is unable to predict the ultimate cost and effects
of such compliance.

         The Comprehensive Environmental Response, Compensation and Liability
Act ("CERCLA"), also known as the "Superfund" law, imposes liability, without
regard to fault or the legality of the original conduct, on certain classes of
persons who are considered to have contributed to the release of a "hazardous
substance" into the environment. These persons include the owner or operator of
the disposal site or sites where the release occurred and companies that
disposed or arranged for the disposal of the hazardous substances. Under CERCLA,
such persons or companies may be subject to joint and several liabilities for
the costs of cleaning up the hazardous substances that have been released into
the environment and for damages to natural resources. Also, it is not uncommon
for neighboring landowners and other third parties to file claims for personal
injury, property damage, and recovery of response costs allegedly caused by the
hazardous substance released into the environment.

         In addition, the U.S. Oil Pollution Act of 1990 (the "OPA") and
regulations promulgated pursuant thereto impose a variety of regulations on
responsible parties related to the prevention of oil spills and liability for
damages resulting from such spills. The OPA establishes strict liability for
owners of facilities that are the site of a release of oil into "waters of the
United States." While OPA liability more typically applies to facilities near
substantial bodies of water, at least one district court has held that OPA
liability can attach if the contamination could enter waters that may flow into
navigable waters.

         Stricter standards in environmental legislation may be imposed in the
oil and gas industry as the result of the reclassification of certain oil and
natural gas exploration and production wastes as "hazardous oil and gas wastes,"
which could make the reclassified wastes subject to more stringent and costly
handling, disposal and clean-up requirements. The impact of any such
requirements, however, would not likely be any more burdensome to NEG than to
any other similarly situated company involved in oil and natural gas exploration
and production.

         The Resource Conservation and Recovery Act ("RCRA") and regulations
promulgated thereunder govern the generation, storage, transfer and disposal of
hazardous wastes. RCRA, however, excludes from the definition of hazardous
wastes "drilling fluids, produced waters, and other wastes associated with the
exploration, development, or production of crude oil, natural gas, or geothermal
energy." Because of this exclusion, many of NEG's operations are exempt from
RCRA regulation. Nevertheless, NEG must comply with RCRA regulations for any of
its operations that do not fall within the RCRA exclusion (such as painting
activities or use of solvents).


                                       30

<PAGE>   31

         Because oil and natural gas exploration and production, and possibly
other activities, have been conducted at some of NEG's properties by previous
owners and operators, materials from these operations remain on some of the
properties and in some instances require remediation. In addition, NEG has
agreed to indemnify some sellers of producing properties from whom NEG has
acquired reserves against certain liabilities for environmental claims
associated with such properties. While NEG does not believe that costs to be
incurred by NEG for compliance and remediating previously or currently owned or
operated properties will be material, there can be no guarantee that such costs
will not result in material expenditures.

         Additionally, in the course of NEG's routine oil and natural gas
operations, surface spills and leaks, including casing leaks of oil or other
materials occur, and as a result, NEG incurs costs for waste handling and
environmental compliance. Moreover, NEG is able to control directly the
operations of only those wells for which it acts as the operator.
Notwithstanding NEG's lack of control over wells in which NEG owns an interest
but is operated by others, the failure of the operator to comply with applicable
environmental regulations may, in certain circumstances, be attributable to NEG.

         NEG is also subject to laws and regulations concerning occupational
safety and health. While it is not anticipated that NEG will be required in the
near future to expend amounts that are material in the aggregate to NEG's
overall operations by reason of occupational safety and health laws and
regulations, NEG is unable to predict the ultimate cost of compliance.

MARKETING AND TRANSPORTATION. Federal legislation and regulatory controls in the
United States have historically affected the price of the natural gas produced
by NEG and the manner in which such production is marketed. The transportation
and sales for resale of natural gas in interstate commerce are regulated
pursuant to the Natural Gas Act of 1938 (the "NGA") and the Federal Energy
Regulatory Commission ("FERC") regulations promulgated thereunder. Maximum
selling prices of certain categories of natural gas, whether sold in interstate
or intrastate commerce, previously were regulated pursuant to The Natural Gas
Policy Act of 1978 ("NGPA"). The NGPA established various categories of natural
gas and provided for graduated deregulation of price controls of several
categories of natural gas and the deregulation of sales of certain categories of
natural gas. All price deregulation contemplated under the NGPA has already
taken place. Subsequently, the Natural Gas Wellhead Decontrol Act of 1989 (the
"Decontrol Act") terminated all remaining NGA and NGPA price and non-price
controls on wellhead sales of domestic natural gas on January 1, 1993. While
natural gas producers may currently make sales at uncontrolled market prices,
Congress could re-enact price controls in the future.

         In April 1992, the FERC issued its restructuring rule, known as Order
No. 636 ("Order No. 636"), that has had a major impact on pipeline operations,
services, and rates. The most significant provisions of Order No. 636: (i)
required interstate pipelines to provide firm and interruptible transportation
solely on an "unbundled" basis, separate from their sales service, and to
convert each pipeline's bundled firm sales service into unbundled firm
transportation service; (ii) provided for the issuance of blanket certificates
to pipelines to provide unbundled sales service giving all utility customers a
chance to purchase their firm supplies from non-pipeline


                                       31

<PAGE>   32

merchants; (iii) required that pipelines provide firm and interruptible
transportation service on a basis that is equal in quality for all natural gas
supplies, whether purchased from the pipeline or elsewhere; (iv) required that
pipelines provide a new, non-discriminatory "no-notice" transportation service
that largely replicates the "bundled" sales service previously provided by
pipelines; (v) established two new, generic programs for the reallocation of
firm pipeline capacity; (vi) required that all pipelines offer access to their
storage facilities on a firm and interruptible basis; (vii) provided for
pregranted abandonment of pipeline sales agreements, interruptible and firm
short-term (defined as one year or less) transportation agreements and
conditional pregranted abandonment of firm long-term transportation service;
(viii) modified transportation rate design by requiring that all fixed costs
related to transportation be recovered through the reservation charge; and (ix)
provided mechanisms for the recovery by pipelines of certain transition costs
occurring from implementation of Order No. 636.

         The rules contained in Order No. 636, as amended by Order No. 636-A
(issued in August 1992) and Order No. 636-B (issued in November 1992)
(collectively, "Order No. 636"), are far reaching and complex. While Order No.
636 does not directly regulate natural gas producers such as NEG, the FERC has
stated that Order No. 636 is intended to foster increased competition within the
gas industry.

         10. OPERATIONAL HAZARDS AND INSURANCE

         NEG's operations are subject to all of the risks inherent in oil and
natural gas exploration, drilling and production. These hazards can result in
substantial losses to NEG due to personal injury and loss of life, severe damage
to and destruction of property and equipment, pollution or environmental damage,
or suspension of operations. NEG maintains insurance of various types customary
in the industry to cover its operations. NEG believes it is insured prudently
against certain of these risks. In addition, NEG maintains operator's extra
expense coverage that provides coverage for the care, custody and control of
wells drilled by NEG. NEG's insurance does not cover every potential risk
associated with the drilling and production of oil and natural gas. NEG does,
however, maintain levels of insurance customary in the industry to limit its
financial exposure in the event of a substantial environmental claim resulting
from sudden and accidental discharges. However, 100% coverage is not maintained.
The occurrence of a significant adverse event, the risks of which are not fully
covered by insurance, could have a material adverse effect on NEG's financial
condition and results of operations. Moreover, no assurance can be given that
NEG will be able to maintain adequate insurance in the future at rates it
considers reasonable. NEG believes that it operates in compliance with
government regulations and in accordance with safety standards which meet or
exceed industry standards.


                                       32
<PAGE>   33

         11. COMPETITION

         The oil and gas industry is intensely competitive in all of its phases.
NEG, which is a small competitive factor in the industry, encounters strong
competition from major oil companies, independent oil and natural gas concerns,
and individual producers and operators, many of which have financial resources,
staffs, facilities and experience substantially greater than those of NEG.
Furthermore, in times of high drilling activity, exploration for and production
of oil and natural gas may be affected by the availability of equipment, labor,
supplies and by competition for drilling rigs. NEG cannot predict the effect
these factors will have on its operations. NEG owns no drilling rigs, and it is
anticipated that its drilling will be conducted by third parties. Furthermore,
the oil and gas industry also competes with other industries in supplying the
energy and fuel requirements of industrial, commercial, and individual
consumers.

         12. OFFICE SPACE

         NEG leases approximately 25,000 square feet of office space in Dallas,
Texas. NEG also leases a small amount of office space in Odessa, Texas, Fort
Smith, Arkansas and Yukon, Oklahoma for its business activities.

         13. EMPLOYEES

         At March 3, 2000, NEG had 46 full-time employees. Of these employees,
six are field-related personnel. NEG does not have any collective bargaining
agreements with employees and believes that relations with its employees are
generally satisfactory.

C. CAPITAL STRUCTURE OF NEG

         1. SENIOR NOTES

         In November 1996, NEG issued $100 million aggregate principal amount of
unregistered 10 3/4% Senior Notes due 2006 (the "Series A Notes"). The net
proceeds of the Series A Notes of approximately $96.1 million were used to repay
approximately $62.0 million of borrowings under a prior facility and to increase
NEG's working capital. In 1997, the Series A Notes were exchanged for registered
10 3/4% Senior Notes due 2006 (the "Series B Notes") which were substantially
identical to the Series A Notes. Collectively, the Series A Notes and Series B
Notes are referred to as the "Series A/B Notes." In August 1997, NEG issued
$65.0 million aggregate principal amount of its unregistered 10 3/4% Senior
Notes (the "Series C Notes"). The net proceeds of the Series C Notes of
approximately $64.8 million were used to repay approximately $23.0 million of
borrowings under the credit facility and to increase NEG's working capital. In
December 1997, NEG exchanged substantially all of the Series A/B Notes and all
of the Series C Notes for registered 10 3/4% Senior Notes due 2006 (the "Series
D Notes"). The Series D Notes are substantially identical to the Series A/B
Notes and the Series C Notes. Collectively, the Series A/B Notes, the Series C
Notes and the Series D Notes are referred to as the "Bonds."

         The Bonds bear interest at an annual rate of 10 3/4%, payable
semiannually in arrears on May 1 and November 1 of each year. The Bonds are
senior, unsecured obligations of NEG,


                                       33

<PAGE>   34


ranking pari passu with all existing and future senior indebtedness of NEG, and
senior in right of payment to all future subordinated indebtedness of NEG.
Subject to certain limitations set forth in the indenture covering the Bonds
(the "Indenture"), NEG and its subsidiaries may incur additional senior
indebtedness and other indebtedness.

         At December 31, 1998 and 1999, unamortized issuance premiums associated
with the Bonds totaled $1,238,513 and $1,080,405, respectively.

         The Indenture provides that the Bonds will be unconditionally
guaranteed (the "Guarantee") by any subsidiary designated by NEG as a Restricted
Subsidiary (a "Guarantor"). As a result of the merger of NEG-OK into NEG on
December 31, 1996, NEG has no Restricted Subsidiaries.

         The Indenture contains certain covenants limiting NEG and any
Restricted Subsidiaries, with respect to the following: (i) assets sales; (ii)
restricted payments; (iii) the incurrence of additional indebtedness and the
issuance of certain redeemable preferred stock; (iv) liens; (v) sale and
leaseback transactions; (vi) lines of business; (vii) dividend and other payment
restrictions affecting subsidiaries; (viii) mergers and consolidations; and (ix)
transactions with affiliates.

         The Bonds mature on November 1, 2006. At any time on or after November
1, 2001, NEG may, at its option, redeem all or any portion of the Bonds at the
redemption prices expressed as percentages of the principal amount of the Bonds
set forth below, plus, in each case, accrued and unpaid interest thereon to the
applicable redemption date, if redeemed during the 12-month period beginning
November 1 of the years indicated below:

         Notwithstanding the foregoing, at any time prior to November 1, 2001,
NEG may, at its option, redeem all or any portion of the Bonds at the Make-Whole
Price, as defined, plus accrued and unpaid interest to the date of redemption.
In addition, in the event NEG consummates one or more Equity Offerings, as
defined, on or prior to November 1, 1999, NEG, at its option, may redeem up to
$35.0 million of the aggregate principal amount of the Bonds with all or a
portion of the aggregate net proceeds received by NEG from such Equity Offering
or Equity Offerings at a redemption price of 110.75% of the aggregate principal
amount of the Bonds so redeemed, plus accrued and unpaid interest thereon to the
redemption date; provided, however, that following such redemption, at least
$65.0 million of the aggregate principal amount of the Bonds remains
outstanding.

         Upon a Change of Control, as defined, NEG will be required, subject to
certain conditions, to offer to repurchase all Bonds at 101% of the principal
amount thereof, plus accrued and unpaid interest to the date of purchase.

         Due to the nonpayment of interest due December 2, 1998, the Bonds were
in default at December 31, 1999.

         2. CREDIT FACILITIES

         On August 29, 1996, NEG, NEG-OK, and Boomer Marketing, entered into a
credit facility with Bank One, as Bank and Administrative Agent, and the Credit
Lyonnais New York Branch, as Bank and Syndication Agent (collectively, the
"Banks"). The credit facility consisted of a $100.0 million reducing revolving
line of credit, with an initial borrowing base of $60.0 million and a $5.0
million term loan. Interest under the reducing revolving line of credit was
payable monthly at the Bank One base rate, as adjusted. The proceeds from the
credit facility were used to repay a prior credit facility and the existing
indebtedness of NEG-OK, resulting in an extraordinary charge of $292,372 or $.0l
per common share in 1996.

         In November 1996, NEG repaid the outstanding borrowings under the
credit facility with a portion of proceeds from the issuance of $100.0 million
principal amount of 10 3/4% Bonds due 2006 (the "Series A Notes"), as discussed
above.

         Also in November 1996, in connection with the issuance of the Series A
Notes, NEG revised the credit facility. The credit facility had a borrowing base
of $25.0 million. The borrowing base may be redetermined at least semi-annually
and may require mandated monthly principal reductions from time to time. The
principal amount of any borrowings is due at maturity, August 29, 2000 and
interest is payable monthly.

         NEG granted liens to the Banks on substantially all of NEG's oil and
natural gas properties, whether currently owned or hereafter acquired, and a
negative pledge on all other oil and natural gas properties. The credit facility
requires, among other things, semiannual engineering reports covering oil and
natural gas properties, and maintenance of certain financial ratios, including
the maintenance of a minimum interest coverage, a current ratio, and a minimum
tangible net worth.

         The credit facility contains other covenants prohibiting cash
dividends, distributions, loans, or advances to third parties, except that cash
dividends on preferred stock will be allowed so long as no event of default
exists or would exist as a result of the payment thereof. In addition, if NEG is
required to purchase or redeem any portion of the Bonds, or if any portion of
the Bonds becomes due, the borrowing base is subject to reduction.

         NEG was required to pay a commitment fee on the unused portion of the
borrowing base equal to 1% per annum.


                                       35
<PAGE>   36


         On December 7, 1998, Bank One and Credit Lyonnais gave notice to NEG
that all outstanding obligations under the credit facility were accelerated and
were immediately due and payable due to certain unspecified Events of Default as
defined in the loan agreement. Effective December 22, 1998, the Banks assigned
the credit facility and all associated liens to Arnos, an affiliated subsidiary
of NEG's Series D preferred stockholder. In a letter dated December 23, 1998,
Arnos (1) rescinded the acceleration of the loan, (2) waived all defaults
existing at that time and (3) made sufficient borrowings available to pay the
interest on the Bonds that was due on November 2, 1998, conditioned upon the
Bankruptcy Court's dismissal of the Involuntary Petition. NEG is currently
paying interest under the Arnos credit facility. NEG had $25 million outstanding
under the Arnos credit facility as of December 31, 1999.

         In connection with its proposed purchase of substantially all of the
oil and gas properties of NEG as of November 1, 1999, Arnos credit bid the $25
million principal indebtedness as permitted by section 363(k) of the Bankruptcy
Code.

         3. PREFERRED STOCK

         In June 1994, NEG consummated the sale of $5.0 million of the Series B
Preferred Stock. Fifty thousand shares of the Series B Preferred Stock were sold
by NEG at $100 per share. The Series B Preferred Stock is convertible into
shares of the Common Stock at a conversion price of $1.625 per share. In
October 1997, 13,813 shares of the Series B Preferred Stock were converted into
Common Stock, leaving 38,687 shares of the Series B Preferred Stock outstanding.
The board of directors declared dividends on the Series B in December of 1998,
which would be made in shares of Series B Preferred Stock. This dividend-in-kind
has not been made and is currently in arrears.

         In June 1995, NEG consummated the sale of $4.0 million of the Series C
Preferred Stock. Forty thousand shares of the Series C Preferred Stock were sold
by NEG at $100 per share. The Series C Preferred Stock is convertible into
shares of the Common Stock at a conversion rate of $2.00 per share. The Series B
Preferred Stock and Series C Preferred Stock require that dividends be paid on
the Series B Preferred Stock and Series C Preferred Stock. before any dividends
are paid on the Common Stock. In October 1997, 17,000 shares of the Series C
Preferred Stock were converted into Common Stock, leaving 23,000 shares of the
Series C Preferred Stock outstanding. The board of directors declared dividends
on the Series C in December of 1998, which would be made in shares of Series C
Preferred Stock. This dividend-in-kind has not been made and is currently in
arrears.

         In August 1996, NEG completed the sale of 100,000 shares of the Series
D Preferred Stock for $10.0 million and 50,000 shares of the Series E Preferred
Stock for $5.0 million. The Series D Preferred Stock and Series E Preferred
Stock are convertible into shares of the Common Stock at a conversion price of
$2.25 per share. As part of such sale, NEG agreed to extend the date at which it
may first redeem the Series B Preferred Stock and Series C Preferred Stock from
June 14, 1997 to June 14, 1999. In October 1997, 40,500 shares of the Series E
Preferred Stock were converted into Common Stock, leaving 9,500 shares of the
Series E Preferred Stock outstanding.

         NEG does not have any long-term incentive plans or defined benefit or
actuarial plans. Therefore, the tables on long-term incentive plan awards and
pension plans are omitted.

         4.       EMPLOYEE STOCK PURCHASE PLAN

         NEG has an Employee Stock Purchase Plan (the "Plan") pursuant to
Section 423(b) of the United States Internal Revenue Code of 1986, as amended.
Pursuant to the Plan, all Eligible Participants may participate in each
semi-annual offering in an amount of not less than 1% or more than 1O% of his
or her base pay in effect as of the Offering Commencement Date of each offering.
At the end of each offering, the employee shall be entitled to purchase stock of
NEG from the payroll deductions through the Offering Period at a price equal to
the lower of:

         (a)     85% of the closing price of the stock on the Offering
                 Commencement Date or the nearest prior business day on which
                 trading occurred on the NASDAQ National Market System; or



                                       42
<PAGE>   43


         (b)      85% of the closing price of the stock on the Offering
                  Termination Date or the nearest prior business day on which
                  trading occurred on the NASDAQ National Market System; or

         (c)      if the Common Stock of NEG is not admitted to trading on any
                  of the aforesaid dates for which closing prices of the stock
                  are to be determined, then reference shall be made to the fair
                  market value of the stock on that date, as determined on such
                  basis as shall be established or specified for purposes of the
                  offering by the Board of Directors.

During 1999, as a result of the pendency of the Chapter 11 Cases, no employees
participated in NEG's Stock Purchase Plan.

         5.       COMPENSATION OF DIRECTORS

         NEG compensates non-employee Board of Directors members in the amount
of $1,000 for each official Board of Directors' meeting and $500 for each Board
of Directors' committee meeting unless such committee meeting is held at the
time of, or in conjunction with, an official Board of Directors' meeting. In
addition, members of the Board of Directors have been granted stock options in
past years. During 1999, no stock options were granted to directors.

         Incorp Inc. (which acts as a petroleum consultant and independent oil
and gas producer) and an affiliated company of former Director, Mr. Norman
Miller, was paid $35,000 for consulting services rendered to NEG by Mr. Miller
during 1998, but no payments were made in 1999. Pursuant to an agreement
effective as of November 11, 1994, Mr. Miller was entitled to receive $500 for
each day he worked on Company matters. Incorp Inc. terminated its relationship
with NEG on December 7, 1998, and Mr. Miller resigned from the Board of
Directors effective February 10, 1999.

         Upon consummation of the Alexander merger, Mr. Bob G. Alexander entered
into a consulting agreement with NEG for a term running from September 1996 to
September 1999 at a compensation level of $150,000 per year. Effective November
23, 1998, Mr. Alexander was appointed President and Chief Executive Officer of
NEG at an annual salary of $250,000 per year. In January 1999, Mr. Alexander was
paid the outstanding amount of $112,500 due under his consulting agreement as
partial compensation for his appointment as NEG's President and Chief Executive
Officer.

         In addition, NEG pays other incidental compensation to executive
officers and directors from time to time, consisting primarily of health
insurance and reimbursement for travel and entertainment expenses on behalf of
NEG.

         6.       EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AND
                  CHANGE-IN-CONTROL ARRANGEMENTS

         In January 1996, NEG executed an employment agreement with Melissa H.
Rutledge, Vice President, Controller and Chief Accounting Officer, which has a
term of three years from the effective date of a "change in control" of NEG. In
March 1997 and April 1998, respectively, NEG executed a similar employment
agreement with each of Philip D. Devlin, Vice President, General Counsel and
Secretary and R. Kent Lueders, Vice President, Corporate Development, (together
with Ms. Rutledge's employment agreement, the "Employment Agreements"). The
Employment Agreements each provide that the three-year term will continuously
roll over (so that at any time during the term of such agreements there is a
remaining term of three years, but in no event beyond the time the executive
and/or officer reaches age 65).

         The Employment Agreements define the "change in control" to have
occurred when (i) a person, entity or group becomes the beneficial owner of a
majority of the securities of NEG ordinarily having the right to vote for
election of directors, (ii) during any consecutive two year period, the
directors at the beginning of the period (together with directors approved by a
vote of 66 2/3% of such initial directors plus directors previously approved by
such 66 2/3% margin) cease to constitute a majority of NEG's Board of Directors,
(iii) any sale, lease, exchange or transfer of all, or substantially all, of
NEG's assets occurs, or (iv) a merger or consolidation occurs with the effect
that any person, entity or group, or the shareholders thereof, become the owner
of securities of the surviving corporation representing a majority of the voting
power of such surviving corporation for the election of directors.

         The Employment Agreements provide for a three year employment term
during which the executive and/or officer receives for each year (i) 100% of the
average of the executive's annual base salary at the time in question and the
executive's annual base salary for each of the preceding two years, and (ii)
100% of the average of the bonuses paid to the executive and/or officer for each
of the preceding three fiscal years. If the executive and/or officer is
discharged without cause or resigns for "good reason" (as defined therein) after
a change in control, then in lieu of the compensation described in the preceding
sentence, the executive and/or officer is entitled to a lump sum cash severance
payment equal to three times the sum of (a) the executive's annual base salary
then in effect, (b) the average of cash bonuses for each of the three previous
years, and (c) the average of fully-vested contributions to retirement plans for
such executive and/or officer for each of the three preceding years. In
addition, at such time, all options and all other retirement or pension
contributions or benefits become fully vested and remain fully exercisable for
360 days.

         Pursuant to an agreement with NEG dated December 3, 1998, each of Ms.
Rutledge, Mr. Devlin and Mr. Lueders agreed to terminate their existing
Employment Agreements; provided that no court (including the bankruptcy court)
reduces or dismisses any of the Severance Pay Benefits (described below)
available to such executives pursuant to NEG's Severance Policy.

         In addition to the Employment Agreements discussed above, NEG entered
into an employment agreement with Jim L. David in March 1997, then Vice
President, Exploration for a






                                       44
<PAGE>   45

two-year term, commencing with the date of consummation of the merger of NEG
with Alexander Energy Corporation. Under such agreement, in the event Mr. David
resigned for a good reason after a "change of control" as defined above, or upon
the discharge of Mr. David without cause during the employment term, Mr. David
would receive severance benefits equal to the sum of (i) his annual base salary
then in effect, (ii) his last annual cash bonus and (iii) the average retirement
plan contributions by NEG on his behalf on a fully vested basis for the last two
fiscal years, multiplied by three (3). Mr. David would also have all stock
options previously granted to him become fully vested and exercisable for a
three-year period (360 days) following termination. Mr. David's Employment
Agreement was terminated in July, 1998 and the benefits payable under this
Employment Agreement were paid and made a part of his separation agreement.
Effective December 1, 1998, Mr. David was re-employed with NEG as an Assistant
to the President; however, he does not have a new employment agreement in
conjunction therewith.

                            VI. THE CHAPTER 11 CASES

A.       FACTORS LEADING TO CHAPTER 11 FILING

         Due to the significant decline in oil prices in 1998, coupled with
unfavorable revisions in estimates of oil and gas reserves during the year, NEG
experienced disappointing operating results in 1998. The revenues generated by
NEG's operations are highly dependent upon the prices of, and demand for, oil
and natural gas. The price received by NEG for its oil and natural gas
production depends on numerous factors beyond NEG's control, including seasonal
price fluctuation, the condition of the U.S. economy, foreign imports, political
conditions in other oil- and natural-gas-producing countries, the actions of the
Organization of Petroleum Exporting Countries and domestic governmental
regulations, legislation and policies. Declines during 1998 in the prices of oil
and gas had a material adverse effect on the carrying value of NEG's oil and gas
properties and NEG's revenues, profitability and cash flows.

B.       COMMENCEMENT OF THE CHAPTER 11 CASES

         On December 4, 1998, certain holders of the Bonds filed an Involuntary
Petition against NEG for an order for relief under chapter 11 of Bankruptcy Code
in the Bankruptcy Court, due to nonpayment of interest due December 2, 1998,
after expiration of a 30-day grace period. On December 23, 1998, NEG filed, in
the Bankruptcy Court, an Answer to and Motion to Dismiss the pending Involuntary
Petition. NEG's Motion affirmed that it (i) was meeting its obligations and
generally paying its debts as they become due, unless such debts were the basis
of a bona fide dispute and (ii) had arranged with the lender under its credit
facility to borrow additional funds sufficient to pay the interest due on the
Bonds, conditioned upon the Bankruptcy Court's dismissal of the Involuntary
Petition. However, on February 8, 1999, the Bankruptcy Court denied NEG's Motion
to Dismiss the Involuntary Petition. On February 11, 1999, the Bankruptcy Court
entered an order for relief with respect to NEG, and BMC filed a voluntary
petition for relief under chapter 11.

C.       SIGNIFICANT EVENTS SINCE COMMENCEMENT OF CHAPTER 11 CASES

         1.       CONTINUATION OF DEBTORS' BUSINESS

         Since the Relief Date, the Debtors have continued to operate their
business and manage their properties as debtors in possession. Due to the
chapter 11 filing, NEG has suspended its exploratory drilling program. NEG has
limited its capital expenditures to ordinary course enhancement of current
production through workovers, recompletions, and other production enhancing
activities deemed to be economic given current oil and gas prices. Development
drilling has been limited to (i) ordinary course non-operated wells in which NEG
owns limited working interests and in which the failure to participate may
result in drainage, depletion or loss of current reserves and (ii) operated
wells deemed to be economical given current oil and gas


                                       53
<PAGE>   54

prices. Large expenditures for developmental drilling may require court
approval, and none are planned at this time.

         2.       STAY OF LITIGATION

         An immediate effect of the filing of a bankruptcy case is the
imposition of the automatic stay under the Bankruptcy Code, which, with limited
exceptions, enjoins the commencement or continuation of all litigation against
the Debtors. This injunction will remain in effect until the Effective Date
unless otherwise modified by the order of the Bankruptcy Court.

         3.       OPERATING ORDERS

         On February 11, 1999, upon entry of the order for relief with respect
to NEG and commencement of the voluntary case with respect to BMC, the Debtors
obtained a number of orders, supported by motions and applications, to authorize
the continued day-to-day operations of the Debtors. These orders included, among
others, (i) an order authorizing the maintenance of business forms and bank
accounts, (ii) an order to pay prepetition wages, reimbursable employee expenses
and employee benefits, (iii) an order to maintain utility services, (iv) an
order authorizing payment of certain critical vendors, (v) an order authorizing
the use of cash collateral, and (vi) an order authorizing the joint
administration of the Chapter 11 Cases.

         4.       APPOINTMENT OF COMMITTEE

         The Committee was originally appointed on February 19, 1999, by the
United States Trustee. The Committee selected the law firm of Andrews & Kurth,
L.L.P. to represent it in the Chapter 11 Cases.

         5.       REPRESENTATION OF THE DEBTORS

                  (a)      Reorganization Counsel

         In July 9, 1999, the Bankruptcy Court entered an order authorizing the
Debtors to engage the law firm of Neligan, Andrews, Bryson & Foley, L.L.P.
(formerly known as Neligan & Averch, L.L.P.) as reorganization counsel in the
Chapter 11 Cases. The firm replaced Weil, Gotshal & Manges, L.L.P. as the
Debtors' reorganization counsel.

                  (b)      Financial Advisors/Accountants

         On February 11, 1999, the Debtors filed an application to retain
PricewaterhouseCoopers ("PwC") as their financial advisors. On February 11,
1999, the Debtors filed an application to retain Ernst & Young as their
accountants. On February 24, 1999, the Bankruptcy Court entered an interim order
authorizing the Debtors' retention of PwC, and on March 9, 1999, the Bankruptcy
Court entered an order authorizing the Debtors retention of Ernst & Young. On
June 29, 1999, the Court entered an order expanding the employment of PwC.

                  (c)      Labor, Corporate and Securities Counsel

         On February 11, 1999, the Debtors filed an application to retain, the
law firm of Akin, Gump, Strauss, Hauer & Feld, L.L.P. ("Akin Gump") as special
counsel for labor, corporate, and securities matters. On March 18, 1999, the
Bankruptcy Court entered an order authorizing the Debtors' retention of Akin,
Gump.

                  (d)      Official Claims Administrator

         On February 11, 1999, the Debtors filed an application to retain
Poorman-Douglas Corporation to act as the official claims administrator of these
Estates. On March 1, 1999, the Bankruptcy Court entered an order authorizing the
employment of Poorman-Douglas for the limited purpose of mailing notice of
commencement of cases pursuant to section 341 of the Bankruptcy Code.

         6.       TERMINATION OF EXCLUSIVITY AND FILING OF COMMITTEE PLAN

         On April 2, 1999, the Committee filed a motion to terminate the
Debtors' exclusive right to file a plan of reorganization pursuant to section
1121 of the Bankruptcy Code. As a hearing conducted on April 22, 1999, the
Bankruptcy Court entered an order granting the motion in part and denying it in
part. The Bankruptcy Court's order required both the Debtors and the Committee
to file a comprehensive summary plan of reorganization by the close of business
on Monday, May 24, 1999. The Debtors did not file a plan of reorganization
within the exclusive period for doing so; therefore, the exclusive period has
expired.

         On February 28, 2000, the Committee filed with the Bankruptcy Court a
joint disclosure statement and proposed plan of reorganization (the "Committee
Plan"). The Committee Plan provides for (i) the possibility of a limited
continuation of NEG's oil and gas business operations; (ii) the creation of a
creditors' trust to which would be transferred substantially all of the cash and
cash equivalents remaining in NEG, the funds held in the registry of the
Bankruptcy Court from the auction of NEG's properties, and all causes of action
for the payment and primary benefit of certain allowed administrative, tax,
priority and miscellaneous secured and unsecured creditors; and (iii) payment in
full of the Arnos Secured Claim in the amount of $25 million, plus interest as
may be due.

<PAGE>   56


         7.       MARKETING AND SALE OF DEBTORS' ASSETS

         On August 4, 1999, NEG and the Committee appeared before the Bankruptcy
Court and announced agreement on the process for marketing NEG and/or its
assets. The Bankruptcy Court entered an order which provided that NEG and the
Committee would employ CIBC World Markets Corp. ("CIBC") to solicit bids for
sale of NEG and/or its assets. NEG assisted CIBC in assembling a data room for
potential bidders to view information regarding NEG's assets. CIBC marketed
NEG's assets pursuant to procedures approved by NEG, the Committee, and the
Bankruptcy Court. In addition, the Bankruptcy Court approved the retention of
Netherland, Sewell & Associates, Inc. to (i) complete its reserve evaluation of
NEG's oil and natural gas properties as of December 31, 1998; (ii) update the
reserve evaluation as of July 1, 1999; and (iii) provide assistance to NEG,
CIBC, and prospective buyers during the marketing process.

         The marketing process culminated in an auction conducted by the
Bankruptcy Court on November 1, 1999. At the auction, bidding on the bulk
properties, without Lake Mongoulois and Mustang Island, ultimately ended at a
high bid of $96.25 million given by Arnos, an affiliated subsidiary of NEG's
Series D preferred stockholder. The Committee, after review, concluded that it
would recommend to the Court that it accept the high bid of $96.25 million. The
Bankruptcy Court signed an order accepting Arnos as the highest bidder on
November 16, 1999. Arnos filed a motion to close the Purchase and Sale Agreement
(the "Arnos PSA") into escrow pending the Bankruptcy Court's approval of either
(i) a plan of reorganization or (ii) a closing of the sale of the properties to
Arnos. The Bankruptcy Court approved this motion and ordered Arnos to pay into
the Bankruptcy Court's registry the sum of $61.25 million, which equals the
purchase price of $96.25 million less the previously escrowed deposit of $9.625
million and the principal balance of $25 million outstanding under the Arnos
credit facility.

         8.       SEVERANCE PROGRAM

         Pursuant to an agreed order between NEG and the Committee, the
Bankruptcy Court entered an order (the "Severance Order") on September 7, 1999,
approving a severance program (the "Severance Program") for NEG's employees. The
Severance Program provides for contingent payments as follows: (a) a "stay-pay"
component payable on the earlier of an employees termination without cause; the
closing of a sale of substantially all NEG's assets or the confirmation of a
Plan of Reorganization; and (b) a "severance" component, whereby upon
termination any employee who does not obtain new employment, or is not offered a
permanent job in Dallas, Texas for a period of at least one year at the same pay
and benefits provided by NEG, shall be entitled to certain severance benefits.
The Severance Order also provided that any employee who participates in the
Severance Program waives and releases any and all claims arising from any
current employment agreement with NEG.

         Effective October 1, 1999, each of Ms. Rutledge, Mr. Devlin and Mr.
Lueders agreed to participate in the Severance Program and void their employment
agreements, provided that all benefits described in the Severance Program are
paid to each, respectively, as prescribed. The Severance Order further provided
that Mr. Alexander and Mr. Devlin would not be entitled to any payments under
the Severance Program until the earlier of (i) confirmation of a plan of




                                       56
<PAGE>   57

reorganization, (ii) conversion to a chapter 7 bankruptcy proceeding, or (iii)
termination of their employment by a trustee appointed by the Bankruptcy Court.

         Payments under this program could be approximately $2 million if both
the stay bonus and severance portions are paid in full.

         VII.     CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE PLAN

         The following is a brief summary of certain federal income tax
consequences that holders of Claims and Equity Interests should consider. This
summary does not address all aspects of federal income taxation that may be
relevant to all persons considering the Plan. Special federal income tax
considerations not discussed in this summary may be applicable to, among other
persons, financial institutions, insurance companies, foreign corporations,
tax-exempt institutions and persons who are not citizens or residents of the
United States. In addition, this summary does not discuss the effect of any
foreign, state or local tax law, the effect of which may be significant.

         This summary is based on the Internal Revenue Code of 1986, as amended
("IRC"), the regulations promulgated thereunder, judicial decisions, and
administrative positions of the Internal Revenue Service (the "Service"). All
section references in this summary are to sections of the IRC. Any change in the
foregoing authorities may be applied retroactively in a manner that could
adversely affect persons considering the Plan.

         No ruling will be sought from the Service with respect to the federal
income tax aspects of the Plan and there can be no assurance that the
conclusions set forth in this summary will be accepted by the Service. No
opinion has been sought or obtained with respect to the tax aspects of the Plan.

         THIS SUMMARY IS INTENDED FOR GENERAL INFORMATION ONLY. PERSONS
CONSIDERING THE PLAN ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS CONCERNING
THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE REORGANIZATION OF THE DEBTORS,
THE RECEIPT OF ANY PAYMENT UNDER THE PLAN, AND THE IMPACT ON THAT PERSON OR ANY
OTHER PERSON OF ANY OBLIGATION IMPOSED UNDER THE PLAN.

A.       TAX CONSEQUENCES TO THE DEBTORS

         1.       DISCHARGE OF INDEBTEDNESS INCOME

         The IRC generally provides that a debtor must include in income the
amount of discharge of indebtedness ("DOI") it realizes when a creditor accepts
less than full payment in satisfaction of its debt. The realized amount of DOI
is generally the difference between the amount of indebtedness and the amount
received by the creditor in exchange therefor. However, the IRC also provides in
Section 108(a) that DOI will not be included in the debtor's taxable income if
the debtor is under the jurisdiction of a court in a case under Title 11 of the
United States Code



                                       57
<PAGE>   58

(related to bankruptcy) and the DOI is granted by the court or is pursuant to a
plan approved by the court. In the event IRC Section 108(a) excludes DOI from
the debtor's income, the debtor's tax attributes will be reduced by the amount
of DOI income so excluded. The tax attributes are generally reduced in a
prescribed order and include NOLs, general business credit carryovers, capital
loss carryovers and the tax basis of its assets. In the alternative, the debtor
may make an election to alter the order of attribute reduction such that the tax
basis of depreciable property would be reduced first.

         Subject to the discussion below, the Debtors believe that they should
not (i) realize DOI or (ii) suffer a reduction in tax attributes with respect to
any Bondholder Claim because the Bonds will be purchased by Arnos and not
discharged by the Debtors. The Debtors will realize DOI with respect to any
other Claim that is discharged in connection with the Plan to the extent of the
difference between the amount of such Claim and the amount of consideration paid
to the respective holder pursuant to the Plan.

         IRC Section 108(e)(4) provides that an acquisition of outstanding debt
by a person related to the debtor from a person unrelated to the debtor will be
treated as an acquisition by the debtor of the debt for purposes of determining
the amount of DOI realized by the debtor. Generally, a corporate acquiror and a
corporate debtor may be related if (in addition to certain additional
requirements) certain persons (actually or constructively) own, directly or
indirectly, more than 50% of the value of all outstanding stock of both
corporations or more than 50% of all classes of voting stock. In the event IRC
Section 108(e)(4) applies, the debtor will be treated as retiring the amount of
the debt acquired by the related person in exchange for the amount of
consideration paid by the related person for such debt. In such a case, the
debtor will realize, as DOI income, the difference between the deemed amount
retired and the consideration paid. To the extent applicable, IRC Section 108(a)
may then preclude recognition of such DOI income and require reduction of tax
attributes in the amount thereof.

         Upon consummation of the Plan, Arnos affiliates will not own no more
than 50% of the voting classes of the Debtors or more than 50% of the value of
the stock of the Debtors. Accordingly, Arnos and the Debtors should not be
related within the meaning of IRC Section 108(e)(4). Even if Arnos and the
Debtors were related, any resulting DOI income to the Debtors should be excluded
from taxable income (but would reduce tax attributes) under IRC Section 108(a)
as discussed herein. The foregoing assumes that the Bonds constitute debt for
federal income tax purposes. If the Bonds were treated as exchanged for equity,
the Bonds would be deemed discharged and would result in DOI income to the
Debtors. In such a case, the DOI income should, in a manner similar to that
discussed below with respect to discharged Claims, be excluded from income under
IRC Section 108(a) and reduce tax attributes. While the Debtors believe that the
Bonds will constitute debt for federal income tax purposes upon consummation of
the Plan, there can be no assurance that the Service would agree with that
conclusion.

         In the case of any discharged Claim with respect to which DOI is
realized by the Debtors, the DOI will be excluded from the Debtors' taxable
income because the discharge of such Claims will occur pursuant to the Plan as
approved by the Bankruptcy Court. As a result of the exclusion from income, the
NOLs of the Debtors will be reduced by the amount of the DOI.




                                       58
<PAGE>   59

         2.       LIMITATION ON NET OPERATING LOSSES


         Based on current available information, the total consolidated NOL
carryforward available with respect to the Debtors is approximately $100 million
as of December 31, 1999. A portion of these NOLs is limited as a result of an
ownership change that occurred with respect to the Debtors in 1996.

         IRC Sections 382 and 383 provide that in the event of an "ownership
change" a loss corporation's ability to use its pre-change NOLs, tax credits and
certain built-in losses will be limited. An ownership change generally occurs
when the percentage of a corporation's stock owned by "5% shareholders" has
increased by more than fifty (50) percentage points over a testing period that
is generally three (3) years. If an ownership change occurs, the corporation's
annual use of its NOL carryovers (and certain built-in losses recognized during
the 5 years following the ownership change) is limited to the "Section 382
Limitation." The Section 382 Limitation is calculated as the value of the
corporation's equity immediately before the ownership change multiplied by the
applicable federal long-term tax-exempt rate (for example, for ownership changes
in March 2000, the rate is 5.84%). IRC Section 382 also provides however that,
in certain cases, a loss corporation may utilize additional pre-change NOLs if
the corporation is treated as having "built-in gains" in excess of certain
statutory thresholds.

         A 5% shareholder is any person that holds five percent (5%) or more of
the stock of the corporation at any time during the testing period. Assuming
that the Bonds are debt for general federal income tax purposes, a holder of
Bonds will not be treated as a shareholder with respect to the Debtors (except
as discussed below). Accordingly, the Debtors believe that they will not incur
an ownership change as a result of the Plan. However, if the Bonds are treated
as exchanged for equity, an ownership change would result and the Debtors would
be subject to the Section 382 Limitation with respect to its NOLs and any other
tax attributes described above. While the Debtors believe that the Bonds will
constitute debt for federal income tax purposes upon consummation of the Plan,
there can be no assurance that the Service would agree with that conclusion.

         However, the temporary treasury regulations under IRC Section 382
provide that an ownership interest in a corporation that is not stock will
nevertheless be treated as stock for purposes of IRC Section 382 if (i) at the
time of issuance or transfer to or by a 5% shareholder of such interest, such
interest offers a potential significant participation in the growth of the
corporation; (ii) treating such interest as stock would result in an ownership
change; and (iii) the amount of pre-change losses at such time exceeds twice the
Section 382 Limitation at such time. At the time of transfer of the Bonds to
Arnos, the Bonds may be viewed as offering a potential significant participation
in the growth of the Debtors. In such a case, the Bonds may be treated as stock
for purposes of IRC Section 382 and an ownership change would result. There can
be no assurance that the Bonds will be treated as debt under IRC Section 382.

         Any shift (deemed or actual) in the ownership of stock of the Debtors,
directly or by attribution, outside the scope of the Plan may trigger (or may
have already triggered) the application of IRC Section 382 and other IRC
provisions which may affect the availability of the





                                       59
<PAGE>   60

Debtors' NOLs. Because the federal income tax consequences of any shift would
depend on the particular facts and circumstances at such time and the
application of complex legislation and regulations, there can be no assurances
as to the effect of any transactions outside the scope of the Plan or the
survival of any NOLs or other carryovers. The charter and the bylaws of the
Reorganized Debtor will be amended to prohibit the transfer of any stock of the
Reorganized Debtor to or by any Person who is, was or would become as a result
of such transfer a 5% shareholder within the meaning of IRC Section 382.

         3.       ISSUANCE OF ADDITIONAL SHARES OF COMMON STOCK

         No gain or loss will be recognized by the Debtors upon the receipt of
money in exchange for the issuance of additional shares of common stock of the
Reorganized Debtor to Arnos or its affiliate pursuant to the Plan.

         4.       ALTERNATIVE MINIMUM TAX

         A corporation's federal income tax liability for a taxable year is
generally the greater of its regular income tax liability or its alternative
minimum tax ("AMT") liability (which is calculated at a 20% tax rate). The
regular corporate tax rate is applied to the corporation's regular taxable
income which may generally be offset by its available NOLs for the taxable year.
In contrast, in calculating alternative minimum taxable income ("AMTI"), NOLs
(as determined for these purposes) may not offset more than 90% of the pre-NOL
AMTI. Thus, if the Debtors have any AMTI, they will be required to pay tax at an
effective rate of 2% of such income (10% of the 20% AMT rate). In addition,
under IRC Section 59A, such AMTI (as adjusted by the rules therein) may be
subject to an environmental tax applicable at the rate of 0.12%.

B.       TAX CONSEQUENCES TO HOLDERS OF EQUITY INTERESTS

         Under the Plan, the holders of Class 14 Preferred Equity Interests and
Class 15 Common Equity Interests will retain their currently held interests.
Although the percentage ownership of the holders of these Equity Interests will
be diluted as a result of the issuance of additional shares of common stock of
the Reorganized Debtor to Arnos or an affiliate, no federal income tax
consequences are anticipated with respect to such holders as a result thereof.

C.       TAX CONSEQUENCES TO HOLDERS OF CLAIMS

         Generally, a holder of a Non-Arnos Bondholder Claim will recognize gain
or loss with respect to its Claim to the extent of the difference between the
amount of consideration paid by Arnos and the adjusted tax basis of the Claim. A
holder of any other Claim discharged by the Debtors under the Plan will
generally recognize gain or loss with respect to its Claim to the extent of the
difference between the consideration received by the holder and the adjusted tax
basis of the Claim. In both instances, the amount of the consideration is
generally the sum of any Cash and the fair market value of any property received
by the holder in exchange for the Claim. Subject to the discussion below, a
holder of a Claim will generally recognize capital gain or loss if the Claim was
a capital asset in the hands of such holder and as long-term or short-term gain
or



                                       60
<PAGE>   61

loss depending generally on the length of time the Claim was held. However, gain
recognized by a holder of a Claim who acquired the Claim at a market discount
and who did not elect to include such discount in income currently will
generally be treated as recognizing ordinary income to the extent of any accrued
market discount with respect to such Claim.

         With respect to any Allowed Non-Arnos Bondholder Claim, a portion of
the consideration received by a holder may be viewed as attributable to accrued
but unpaid interest. In that event, a holder would recognize ordinary income to
the extent that the consideration received is attributable to interest accrued
during the period the holder held the Allowed Non-Arnos Bondholder Claim and not
previously included in income. The gain (or loss) that a holder would otherwise
recognize with respect to its Claim would decrease (or increase) by the amount
of such recognized ordinary income. A holder that was previously required to
include interest income under its method of accounting would recognize a loss to
the extent that the consideration attributable to such interest is less than the
amount previously included in income by such holder. In the case of a cramdown
under Alternative B of the treatment of the Bondholder Claims, the Debtors
intend to treat the distribution of a beneficial interest in the Creditors'
Trust to a Bondholder as a payment of accrued interest.

THE FOREGOING IS INTENDED TO BE A SUMMARY ONLY AND IS NOT INTENDED AND SHALL NOT
CONSTITUTE A TAX OPINION, TAX ADVICE OR ANY REPRESENTATION OR FORM OF LEGAL
OPINION BY THE DEBTORS AND THEIR COUNSEL REGARDING THE TAX CONSEQUENCES OF
CONFIRMATION AND EXECUTION OF THE PLAN AS TO ANY HOLDER OF A CLAIM OR EQUITY
INTEREST WITH RESPECT TO THE DEBTORS. IT IS NOT A SUBSTITUTE FOR CAREFUL TAX
PLANNING OR CONSULTATION WITH A TAX ADVISOR. THE FEDERAL, STATE, LOCAL, AND
FOREIGN TAX CONSEQUENCES OF THE PLAN ARE COMPLEX AND, IN SOME CASES, UNCERTAIN.
SUCH CONSEQUENCES MAY ALSO VARY BASED UPON THE INDIVIDUAL CIRCUMSTANCES OF EACH
HOLDER OF A CLAIM OR EQUITY INTEREST. ACCORDINGLY, EACH HOLDER OF A CLAIM OR
EQUITY INTEREST IS STRONGLY URGED TO CONSULT SUCH HOLDER'S OWN TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL, AND FOREIGN TAX CONSEQUENCES OF THE PLAN.

                                VIII. LITIGATION

A.       LITIGATION CLAIMS AGAINST NEG

         The following is a description of the material litigation Claims
against NEG. Each of these Claims is provided specific treatment in the Plan.

         1.       BUCKLES V. NEG

         Plaintiff filed suit as a putative class representative on September 5,
1997, in state court in Canadian County, Oklahoma, for allegedly due and unpaid
royalties. NEG filed its answer on September 29, 1997, with an offer of judgment
for $3,000. The plaintiff rejected the offer of




                                       61
<PAGE>   62

judgment. Discovery is pending, and the hearing on class certification has been
delayed. Proceedings are stayed due to the pendency of the Chapter 11 Cases.

         2.       SOUTHERLAND V. NEG

         Plaintiff filed suit on January 16, 1998, in state court in Harrison
County, Texas, asserting that NEG wells caused damage to the plaintiff's wells.
NEG filed an answer of denial on February 20, 1998. NEG believes that it is
insured for the amount of any loss. Discovery is stayed, and the parties are in
negotiations for a release of the plaintiff's claim. Proceedings are stayed due
to the pendency of the Chapter 11 Cases.

         3.       MILTON VAUGHN V. NEG AND EAGLE SERVICES

         Plaintiff filed suit on February 10, 1998, in state court in Iberville
Parish, Louisiana, for  injuries allegedly suffered in a fall. NEG's
insurance carrier is handling the defense, and NEG believes it is fully insured
for any loss in respect of such litigation. An answer was filed on April 2,
1998. Discovery is pending, and proceedings are stayed due to the pendency of
the Chapter 11 Cases.

         4.       LANDRY AND DUPREE V. EXXON, PANACO, NEG, ET AL.

         Plaintiffs filed suit on August 21, 1998, in state court in Iberville
Parish, Louisiana, for unspecified damages and restoration costs associated with
an oil spill on the plaintiffs' property. Two of NEG's insurance carriers are
handling the defense, and NEG believes it is fully insured for any loss in
respect of such litigation. Discovery is pending. The state court has ordered
production of NEG's and Panaco's records regarding oil spills and remediation
efforts.

B.       CAUSES OF ACTION TO BE TRANSFERRED TO THE CREDITORS' TRUST

         1.       AVOIDANCE ACTIONS

         Section 547 of the Bankruptcy Code enables a debtor in possession to
avoid a transfer to a creditor made within ninety days before the petition date
(or within one year before the petition date in the case of a transfer to an
insider) if the transfer was made on account of an antecedent debt and enabled
the creditor to receive more than it would in a liquidation. A creditor has
defenses to the avoidance of such a preferential transfer based upon, among
other things, the transfer's occurring as part of the ordinary course of the
debtor's business or that, subsequent to the transfer, the creditor provided the
debtor with new value. Section 548 of the Bankruptcy Code allows a debtor in
possession to avoid a transfer to a creditor made within one year before the
petition date if (i) the transfer was made with actual intent to hinder, delay,
or defraud other creditors or (ii) the transfer was for less than reasonably
equivalent value and the debtor was insolvent or undercapitalized at the time of
the transfer or became insolvent or undercapitalized as a result of the
transfer.

         The Debtors have begun their analysis of payments by the Debtors to
creditors prior to






                                       62
<PAGE>   63

the Petition Date, to determine whether such payments may be avoidable as
preferential or fraudulent transfers. The Debtors are reviewing files containing
payment histories for all operating accounts of the Debtors for the period
September 5, 1998, though December 4, 1998. Based on the Debtors' analysis of
these records, it appears that the Debtors, in the aggregate, made prepetition
disbursements in excess of approximately $1.5 million.

         This section is intended only as a general description of payments made
within the time period set forth above, and does not constitute an admission of
any fact relevant to a cause of action to avoid a preferential or fraudulent
transfer. Moreover, the payment totals set forth above are preliminary and are
likely to change as the Debtors' analysis of preferences and fraudulent
transfers progresses.

         2.       D&O AND RELATED LITIGATION

         The Debtors, the Committee and/or specific creditors will evaluate
whether the Debtors have meritorious causes of action against their former and
present directors, officers, and auditors. In the event the Creditors' Trust is
created, the Debtors will transfer to the Creditors' Trust all of their right,
title, and interest in and to such causes of action. The Creditors' Trustee will
be responsible for final evaluation and, if deemed appropriate, filing,
prosecution and/or settlement of such causes of action. The Committee has
already notified the Debtors that the Committee believes such causes of action
may exist. The Debtors believe that any such causes of action are without merit.

         2.       PARTIES IN INTEREST ENTITLED TO VOTE

         Any holder of a Claim against or Equity Interest in the Debtors at the
date on which the order is entered approving the Disclosure Statement whose
Claim or Equity Interest has not previously been disallowed by the Bankruptcy
Court is entitled to vote to accept or reject the Plan, if such Claim or Equity
Interest is impaired under the Plan and either (i) such holder's Claim or Equity
Interest has been scheduled by the Debtors (and such Claim or Equity Interest is
not scheduled as disputed, contingent, or unliquidated) or (ii) such holder
has filed a proof of claim or proof of interest on or before June 21, 2000, the
last date set by the Bankruptcy Court for such filings. Any Claim or Equity
Interest as to which an objection has been filed is not entitled to vote, unless
the Bankruptcy Court, upon application of the holder to whose Claim or Equity
Interest an objection has been made, temporarily allows such Claim or Equity
Interest in an amount that it deems proper for the purpose of accepting or
rejecting the Plan. Any such application must be heard and determined by the
Bankruptcy Court on or before commencement of the Confirmation Hearing. A vote
may be disregarded if the Bankruptcy Court determines, after notice and a
hearing, that such vote was not solicited or procured in good faith or in
accordance with the provisions of the Bankruptcy Code.

         3.       DEFINITION OF IMPAIRMENT

         As set forth in section 1124 of the Bankruptcy Code, a class of claims
or equity interests is impaired under a plan of reorganization unless, with
respect to each claim or equity interest of such class, the plan:

                  (a)      leaves unaltered the legal, equitable, and
                           contractual fights of the holder of such claim or
                           equity interest; or

                  (b)      notwithstanding any contractual provision or
                           applicable law that entitles the holder of a claim or
                           equity interest to demand or receive accelerated
                           payment of such claim or equity interest after the
                           occurrence of a default:

                           (i)      cures any such default that occurred before
                                    or after the commencement of the case under
                                    the Bankruptcy Code, other than a default of
                                    a kind specified in section 365(b)(2) of the
                                    Bankruptcy Code;

                           (ii)     reinstates the maturity of such claim or
                                    interest as it existed before such default;



                                       64
<PAGE>   65

                           (iii)    compensates the holder of such claim or
                                    interest for any damages incurred as a
                                    result of any reasonable reliance on such
                                    contractual provision or such applicable
                                    law; and

                           (iv)     does not otherwise alter the legal,
                                    equitable or contractual rights to which
                                    such claim or interest entitles the holder
                                    of such claim or interest.

         4.       CLASSES IMPAIRED UNDER THE PLAN

         The following Classes of Claims and Equity Interests are impaired under
the Plan, and holders of Claims and Equity Interests in such Classes are
entitled to vote to accept or reject the Plan:

                                    Class 1A -- Other Priority Claims
                                    Class 1B -- BMC Other Priority Claims
                                    Class 2 -- Arnos Secured Claim
                                    Class 3 -- Kauffman County Secured Claim
                                    Class 4 -- Baker Atlas Secured
                                    Class 5A -- Other Secured Claims
                                    Class 5B -- BMC Secured Claims
                                    Class 6 -- Southerland Tort Claims
                                    Class 7 -- Buckles Class Action Claim
                                    Class 8 -- Milton Vaughn Claim
                                    Class 9 -- Landry Claim
                                    Class 10 -- Bondholder Claims
                                    Class 11A -- Trade Claims
                                    Class 11B -- BMC Trade Claims
                                    Class 12 -- Intercompany Claims
                                    Class 13 -- Preferred Equity Interests
                                    Class 14 -- Common Equity Interests
                                    Class 15 -- BMC Equity Interests

         Class 13 (Preferred Equity Interests), Class 14 (Common Equity
Interests), and Class 15 (BMC Equity Interests) are deemed to have rejected the
Plan and therefore are not entitled to vote on the Plan. Administrative Claims,
Priority Tax Claims, and Involuntary Gap Claims are unclassified; their
treatment is prescribed by the Bankruptcy Code, and the holders of such Claims
are not entitled to vote on the Plan. Accordingly, each holder of a Claim (other
than an Administrative Claim, a Priority Tax Claim, or an Involuntary Gap Claim)
is entitled to vote to accept or reject the Plan.

         5.       VOTE REQUIRED FOR CLASS ACCEPTANCE

         The Bankruptcy Code defines acceptance of a plan by a class of claims
as acceptance by holders of at least two-thirds in dollar amount, and more than
one-half in number, of the claims of that class which actually cast ballots for
acceptance or rejection of the Plan. Thus, class





                                       65
<PAGE>   66

acceptance takes place only if at least two-thirds in amount and a majority in
number of the holders of claims voting cast their ballots in favor of
acceptance.

         The Bankruptcy Code defines acceptance of a plan by a class of equity
interests as acceptance by holders of at least two-thirds in amount of the
equity interests of that class that actually cast ballots for acceptance or
rejection of the plan. Thus, class acceptance takes place only if at least
two-thirds in amount of the holders of equity interests voting cast their
ballots in favor of acceptance.

B.       CONFIRMATION HEARING

         Section 1128(a) of the Bankruptcy Code requires the Bankruptcy Court,
after notice, to hold a hearing on confirmation of a plan. By order of the

         Objections to confirmation of the Plan are governed by Bankruptcy Rule
9014. UNLESS AN OBJECTION TO CONFIRMATION IS TIMELY SERVED AND FILED, THE
BANKRUPTCY COURT MAY NOT CONSIDER IT.

C.       REQUIREMENTS FOR CONFIRMATION OF A PLAN

         At the Confirmation Hearing, the Bankruptcy Court must determine
whether the Bankruptcy Code's requirements for confirmation of the Plan have
been satisfied, in which event the Bankruptcy Court will enter an order
confirming the Plan. As set forth in section 1129 of the Bankruptcy Code, these
requirements are as follows:

                  1. The plan complies with the applicable provisions of the
         Bankruptcy Code.

                  2. The proponents of the plan complied with the applicable
         provisions of the Bankruptcy Code.

                  3. The plan has been proposed in good faith and not by any
         means forbidden by law.

                  4. Any payment made or promised by the debtors, by the plan
         proponents, or by a person issuing securities or acquiring property
         under the plan, for services or for costs and expenses in, or in
         connection with, the case, or in connection with the plan and incident
         to the case, has been approved by, or is subject to the approval of the
         Bankruptcy Court as reasonable.

                  5. (a) (i) The proponent of the plan has disclosed the
         identity and affiliations of any individual proposed to serve, after
         confirmation of the plan, as a director, officer, or voting trustee of
         the debtors, an affiliate of the debtors participating in a joint plan
         with the debtors, or a successor to the debtors under the plan; and

                         (ii) the appointment to, or continuance in, such
         office of such individual, is consistent with the interests of
         creditors and equity security holders and with public policy; and

                     (b) the proponent of the plan has disclosed the identity
         of any insider that will be employed or retained by the reorganized
         debtors, and the nature of any compensation for such insider.







                                       67
<PAGE>   68

                  6. Any governmental regulatory commission with jurisdiction,
         after confirmation of the plan, over the rates of the debtor has
         approved any rate change provided for in the plan, or such rate change
         is expressly conditioned on such approval.

                  7. With respect to each impaired class of claims or interests:

                        (a) each holder of a claim or interest of such class
         has accepted the plan or will receive or retain under the plan on
         account of such claim or interest property of a value, as of the
         effective date of the plan, that is not less than the amount that such
         holder would so receive or retain if the Debtors were liquidated on
         such date under chapter 7 of the Bankruptcy Code on such date; or

                        (b) if section 1111 (b)(2) of the Bankruptcy Code
         applies to the claims of such class, the holder of a claim of such
         class will receive or retain under the plan on account of such claim
         property of a value, as of the effective date of the plan, that is not
         less than the value of such holder's interest in the estate's interest
         in the property that secures such claims.

                  8. With respect to each class of claims or interests:

                        (a) such class has accepted the plan; or

                        (b) such class is not impaired under the plan.

                  9. Except to the extent that the holder of a particular claim
         has agreed to a different treatment of such claim, the plan provides
         that:

                        (a) with respect to a claim of a kind specified in
         section 507(a)(l) or 507(a)(2) of the Bankruptcy Code, on the effective
         date of the plan, the holder of such claim will receive on account of
         such claim cash equal to the allowed amount of such claim;

                        (b) with respect to a class of claims of a kind
         specified in section 507(a)(3), 507(a)(4), 507(a)(5) or 507(a)(6) of
         the Bankruptcy Code, each holder of a claim of such class will receive:

                        (a) (i) if such class has accepted the plan, deferred
         cash payments of a value, as of the effective date of the plan, equal
         to the allowed amount of such claim; or

                            (ii) if such class has not accepted the plan,
         cash on the effective date of the plan equal to the allowed amount of
         such claim; and

                        (c) with respect to a claim of a kind specified in
         section 507(a)(7) of the Bankruptcy Code, the holder of a claim will
         receive on account of such claim deferred cash payments, over a period
         not exceeding six years after the date of





                                       68
<PAGE>   69

          assessment of such claim, of a value, as of the effective date of the
          plan, equal to the allowed amount of such claim.

                  10. If a class of claims is impaired under the plan, at least
         one class of claims that is impaired has accepted the plan, determined
         without including any acceptance of the plan by any insider holding a
         claim of such class.

                  11. Confirmation of the plan is not likely to be followed by
         the liquidation, or the need for further financial reorganization, of
         the debtors or any successor to the debtors under the plan, unless such
         liquidation or reorganization is proposed in the plan.

                  12. All fees payable under 28 U.S.C. Section 1930, as
          determined by the Bankruptcy Court at the hearing on confirmation of
          the plan, have been paid or the plan provides for the payments of all
          such fees on the effective date of the plan.

                  13. The plan provides for the continuation after its effective
         date of payment of all retiree benefits, as that term is defined in
         section 1114 of the Bankruptcy Code, at the level established pursuant
         to subsection (e)(1)(B) or (g) of section 1114, at any time prior to
         confirmation of the plan, for the duration of the period the Debtors
         has obligated itself to provide such benefits.

         The Debtors believe that the Plan satisfies all the statutory
requirements of chapter 11 of the Bankruptcy Code, that the Debtors has complied
or will have complied with all the requirements of chapter 11, and that the Plan
is proposed in good faith.

         The Debtors believe that holders of all Allowed Claims and Equity
Interests impaired under the Plan will receive payments under the Plan having a
present value as of the Effective Date not less than the amounts likely to be
received if the Debtors were liquidated in a case under chapter 7 of the
Bankruptcy Code. At the Confirmation Hearing, the Bankruptcy Court will
determine whether holders of Allowed Claims or Allowed Equity Interests would
receive greater distributions under the Plan than they would receive in a
liquidation under chapter 7.

         The Debtors also believe that the feasibility requirement for
confirmation of the Plan is satisfied by the fact that the Debtors' future
operating revenues will be sufficient to satisfy the Debtors' obligations under
the Plan in addition to supporting sustainable growth of the enterprise. These
facts and others demonstrating the confirmability of the Plan will be shown at
the Confirmation Hearing.

D.       CRAMDOWN

         In the event that any impaired Class of Claims or Equity Interests does
not accept the Plan, the Bankruptcy Court may still confirm the Plan at the
request of the Debtors if, as to each impaired Class which has not accepted the
Plan, the Bankruptcy Court determines that the Plan "does not discriminate
unfairly" and is "fair and equitable" with respect to that Class. A plan of






                                       69
<PAGE>   70

reorganization "does not discriminate unfairly" within the meaning of the
Bankruptcy Code if no Class receives more than it is legally entitled to receive
for its claims or equity interests.

         "Fair and equitable" has different meanings with respect to the
treatment of secured and unsecured claims. As set forth in section 1129(b)(2)
of the Bankruptcy Code, those meanings are as follows:

                  1.       With respect to a class of secured claims, the plan
                           provides:

                           (a) (i)  that the holders of such claims retain the
         liens securing such claims, whether the property subject to such liens
         is retained by the Debtors or transferred to another entity, to the
         extent of the allowed amount of such claims; and

                               (ii) that each holder of a claim of such class
         receive on account of such claim deferred cash payments totaling at
         least the allowed amount of such claim, of a value, as of the effective
         date of the plan, of at least the value of such holder's interest in
         the estate's interest in such property;

                           (b) for the sale, subject to section 363(k) of the
         Bankruptcy Code, of any property that is subject to the liens securing
         such claims, free and clear of such liens, with such liens to attach to
         the proceeds of such sale, and the treatment of such liens on proceeds
         under clause (a) and (b) of this subparagraph; or

                           (c) the realization by such holders of the
         "indubitable equivalent" of such claims.

                  2.       With respect to a class of unsecured claims, the plan
                           provides:

                           (a) that each holder of a claim of such class receive
         or retain on account of such claim property of a value, as of the
         effective date of the plan, equal to the allowed amount of such claim;
         or

                           (b) the holder of any claim or interest that is
         junior to the claims of such class will not receive or retain under the
         plan on account of such junior claim or interest any property.

                  3.       With respect to a class of equity interests, the plan
                           provides:

                           (a) that each holder of an interest of such class
         receive or retain on account of such interest property of a value, as
         of the effective date of the plan, equal to the greatest of the allowed
         amount of any fixed liquidation preference to which such holder is
         entitled, any fixed redemption price to which such holder is entitled
         or the value of such interest; or

                                (b) that the holder of any interest that is
         junior to the interests of such class will not receive or retain under
         the plan on account of such junior interest any property.

         In the event that one or more Classes of impaired Claims or Equity
Interests reject the Plan, the Bankruptcy Court will determine at the
Confirmation Hearing whether the Plan is fair and equitable with respect to, and
does not discriminate unfairly against, any rejecting impaired Class of claims
or equity interests. For the reasons set forth above, the Debtors believe the
Plan does not discriminate unfairly against, and is fair and equitable with
respect to, each impaired Class of Claims or Equity Interests.

                                 X. RISK FACTORS

         The following is intended as a summary of certain risks associated with
the Plan, but it is not exhaustive and must be supplemented by the analysis and
evaluation made by each holder of a Claim or Equity Interest of the Plan and
this Disclosure Statement as a whole with such holder's own advisors.

A.       INSUFFICIENT ACCEPTANCES

         For the Plan to be confirmed, each impaired Class of Claims and Equity
Interests is given the opportunity to vote to accept or reject the Plan. With
regard to such impaired voting Classes; the Plan will be deemed accepted by a
Class of impaired Claims if the Plan is accepted by claimants of such Class
actually voting on the Plan who hold at least two-thirds (2/3) in amount and
more than one-half (1/2) in number of the total Allowed Claims of the Class
voted. In addition, the Plan will be deemed accepted by an impaired Class of
Equity Interests if at least two-thirds (2/3) of the holders of Equity Interests
in such Class cast ballots voting to accept the Plan. Only those members of a
Class who vote to accept or reject the Plan will be counted for voting purposes.
The Debtors reserve the right to request confirmation pursuant to the cramdown
provisions in section 1129(b) of the Bankruptcy Code, which will allow
confirmation of the Plan regardless of the fact that a particular Class of
Claims or Equity Interests has not accepted the Plan. However, there can be no
assurance that any impaired Class of Claims under the Plan will accept the Plan
or that the Debtors would be able to use the cramdown provisions of the
Bankruptcy Code for confirmation of the Plan.

B.       CONFIRMATION RISKS

         The following specific risks exist with respect to confirmation of the
Plan:

                  (i) Any objection to confirmation of the Plan filed by a
         member of a Class of Claims or Equity Interests can either prevent
         confirmation of the Plan or delay confirmation for a significant period
         of time.





                                       71
<PAGE>   72

                  (ii) Since the Debtors may be seeking to obtain approval of
         the Plan over the rejection of one or more impaired Classes of Claims,
         the cramdown process could delay confirmation.

C.       CONDITIONS PRECEDENT

         Confirmation of the Plan and occurrence of the Effective Date are
subject to certain conditions precedent that may never occur. The Debtors,
however, are working diligently with all parties in interest to ensure that all
conditions precedent are satisfied.

XI.      ALTERNATIVES TO CONFIRMATION AND CONSUMMATION OF THE PLAN

         The Debtors have evaluated several reorganization alternatives to the
Plan, including the continued operation of the Debtors under their current
operating and debt structures, consummating the Arnos acquisition transaction as
an asset sale under section 363 of the Bankruptcy Code, and the liquidation of
the Debtors. After studying these alternatives, the Debtors concluded that the
Plan is the best alternative and will maximize recoveries by holders of Claims,
assuming confirmation of the Plan and consummation of the transactions
contemplated by the Plan. The following discussion provides a summary of the
Debtors' analysis leading to its conclusion that the Plan will provide the
highest value to holders of Claims.

A.       CONTINUED OPERATION UNDER PREPETITION OPERATING AND DEBT STRUCTURE

         The Debtors' pre-Petition Date operating and debt structure provided
insufficient income to meet the Debtor's obligations. As noted above, the
operating losses of the recent past and the uncertainty of achieving future
profits under the existing operating structure, raised substantial doubt
regarding the Debtors' ability to continue as a going concern without a
substantial reorganization.

         Accordingly, the Debtors determined that to continue operation under
their existing operating and debt structure, or implementing the needed
restructuring outside of chapter 11, would not have remedied the financial
problems to which the Debtors were subject.

B.       SALE ALTERNATIVE

         The Bankruptcy Court has approved the sale of certain of the Debtors'
assets to Arnos, and the transaction can be consummated as an asset sale under
section 363 of the Bankruptcy Code. However, Arnos will provide an additional $2
million in cash for unsecured creditors if the transaction is consummated upon
the terms set forth in the Plan. Accordingly, the Debtors believe that
confirmation and consummation of the Plan will provide at least $2 million in
additional value for unsecured creditors that if the Arnos transaction occurs as
a standalone sale under section 363 of the Bankruptcy Code.



                                       72
<PAGE>   73

C.       LIQUIDATION ALTERNATIVE

         The Debtors also have analyzed whether a chapter 7 liquidation of the
assets of the Debtors would be in the best interest of holders of Claims and
Equity Interests. That analysis reflects a liquidation value that is
substantially lower than the value that may be realized through the Plan. The
Debtors believe that liquidation would result in substantial diminution in the
value to be realized by holders of Claims because of (i) the failure to realize
the greater going-concern value of the Debtors' assets; (ii) additional
administrative expenses involved in the appointment of a trustee or trustees,
attorneys, accountants, and other professionals to assist such trustee(s) in the
case of a chapter 7 proceeding); (iii) additional expenses and claims, some of
which would be entitled to priority in payments, which would arise by reason of
the liquidation and from the rejection of leases and other executory contracts
in connection with a cessation of the Debtors' operations; and (iv) the
substantial time which would elapse before creditors would receive any
distribution in respect of their Claims. Consequently, the Debtors believe that
the Plan, which provides for the continuation of the Debtors' core business,
provides a substantially greater return to holders of Claims than would
liquidation.

                                 XII. CONCLUSION

         The Debtors urge holders of Claims to vote to ACCEPT the Plan and to
evidence such acceptance by returning their ballots so that they will be
received by 5:00 p.m., Central Time, on May ____,2000.

debts due to one of the Debtors may be set off against the debts of the other
Debtor. Substantive consolidation shall not merge or otherwise affect the
separate legal existence of each Debtor, other than with respect to distribution
rights under this Plan; substantive consolidation shall have no effect on valid,
enforceable and unavoidable liens, except for liens that secure a Claim that is
eliminated by virtue of substantive consolidation and liens against Collateral
that are extinguished by virtue of substantive consolidation; and substantive
consolidation shall not have the effect of creating a Claim in a class different
from the class in which a Claim would have been placed in the absence of
substantive consolidation.

                    EXECUTORY CONTRACTS AND UNEXPIRED LEASES

         10.1 GENERAL TREATMENT; ASSUMED IF NOT REJECTED. The Plan constitutes
and incorporates a motion by the Debtors to assume, as of the Effective Date,
all prepetition executory contracts and unexpired leases to which the Debtors
are a party, except for executory contracts or unexpired leases that (a) have
been assumed or rejected pursuant to Final Order of the Bankruptcy Court, (b)
are the subject of a separate motion pursuant to section 365 of the Bankruptcy
Code to be filed and served by the Debtors on or before the Confirmation Date,
or (c) are designated on Exhibit "2" of the Plan as executory contracts and
unexpired leases which the Debtors intend to reject.

         10.2 CURE PAYMENTS AND RELEASE OF LIABILITY. All cure payments which
may be required by section 365(b)(l) of the Bankruptcy Code under any executory
contract or unexpired lease that is assumed, or assumed and assigned, under this
Plan shall be made on or before the Initial Distribution Date; provided,
however, that in the event of a dispute regarding the amount of any cure
payments, the cure of any other defaults, the ability of any party to provide
adequate assurance of future performance, or any other matter pertaining to
assumption or assignment, the Reorganized Debtor shall make such cure payments
and cure such other defaults and provide adequate assurance of future
performance, all as may be required by section 365(b)(l), of the Bankruptcy Code
only following the entry of a Final Order resolving such dispute. To the extent
that a party to an assumed executory contract or unexpired lease has not filed
an appropriate pleading with the Bankruptcy Court on or before the thirtieth
(30th) day after the Effective Date disputing the amount of any cure payments
offered to it, disputing the cure of any other defaults, disputing the
promptness of the cure payments, or disputing the provisions of adequate
assurance of future performance, then such party shall be deemed to have waived
its right to dispute such matters.

         10.3 BAR TO REJECTION DAMAGES. If the rejection of an executory
contract or an unexpired lease by the Debtors results in damages to the other
party or parties to such contract or lease, a Claim

                                                                              23
<PAGE>   28

for such damages shall be forever barred and shall not be enforceable against
the Debtors or their respective properties or agents, successors, or assigns,
unless a proof of Claim is filed with the Bankruptcy Court and served upon the
Reorganized Debtor by the earlier of (a) 30 days after the Confirmation Date or
(b) such other deadline as the Bankruptcy Court may set for asserting a Claim
for such damages.

         10.4 REJECTION CLAIMS. Any Claim arising from the rejection of an
unexpired lease or executory contract and not barred by section 10.3 of the Plan
shall be treated as a Trade Claim pursuant to the Plan; provided, however, that
any Claim based upon the rejection of an unexpired lease of real property shall
be limited in accordance with section 502(b)(6) of the Bankruptcy Code and state
law mitigation requirements. Nothing contained herein shall be deemed an
admission by the Debtors that such rejection gives rise to or results in a Claim
or shall be deemed a waiver by the Debtors of any objections to such Claim if
asserted.

in writing by the Debtors at any time before confirmation, provided that this

to be made pursuant to this Plan in respect of such Claim, claims of any nature
whatsoever that the Debtors may have against the holder of such Claim, but

              JOINT DISCLOSURE STATEMENT UNDER SECTION 1125 OF THE
                BANKRUPTCY CODE WITH RESPECT TO THE JOINT PLAN OF
               REORGANIZATION PROPOSED BY THE CREDITORS COMMITTEE


                                       I.

                                  INTRODUCTION

         On December 4, 1998 ("Commencement Date"), certain holders of Notes (as
defined in the Plan) filed an involuntary petition in bankruptcy under Section
303 (11 U.S.C. Section 101 et. seq.) of the Bankruptcy Code against National
Energy Group, Inc. ("NEG" or the "Company"). After a trial on the merits, the
Bankruptcy Court presiding over the case ruled in favor of the petitioning
noteholders and on February 12, 1999 entered an order for relief. Shortly
thereafter, NEG, together with Boomer Marketing, Inc. converted the cases to
voluntary ones under Chapter 11 with the United States Bankruptcy Court for the
Northern District of Texas (the "Bankruptcy Court"). Subsequently, the Chapter
11 cases were administratively consolidated under Case No. 98-80258-HCA-l1.
Since February, 1999, the Debtors have continued to operate their businesses as
debtors-in-possession pursuant to Sections 1107 and 1108 of the Bankruptcy Code.
On or about February 19, 1999, the Office of the United States Trustee (the
"U.S. Trustee") appointed an Official Committee of Unsecured Creditors (the
"Creditors' Committee") in the Chapter 11 Cases.

         On or about February 14, 2000, the Creditors Committee filed its Plan
of Reorganization (the "Plan") and this Disclosure Statement. The Creditors
Committee submits this Disclosure Statement under Section 1125 of the Bankruptcy
Code with respect to the Plan in connection with the solicitation of votes to
accept or reject the Plan. A copy of the Plan is attached hereto as Exhibit "A".
Capitalized terms used herein, if not defined herein, have the defined meanings
set forth in the Plan.

confirmation of the Plan. The hearing on confirmation may be adjourned from
time to time without further written notice.

                                      III.

                                  PLAN OVERVIEW

         The Plan treats all Claims and Equity Interests fairly and equitably.
The following is a brief summary of the Plan's treatment of Claims against and
Equity Interests in the Debtors. This summary is qualified in its entirety by
reference to the provisions of the entire Plan. A copy of the Plan is attached
hereto as Exhibit "A". You are urged to read the Plan in its entirety. To the
extent there is any conflict between this Disclosure Statement and the Plan, the
terms of the Plan control.

         The Plan provides for the possibility of a limited continuation of the
Debtors oil and natural gas business operations. The Plan contemplates the
creation of a Creditors Trust to which will be transferred at confirmation
substantially all the cash and cash equivalents of the Debtors, the funds held
in escrow from the Arnos Corporation purchase of oil and gas assets from the
Debtors and all the Debtors' causes of action for the payment and primary
benefit of allowed claims of administrative, tax, priority, miscellaneous
secured and unsecured trade and note creditors.

         Allowed Administrative Expense Claims, including Allowed Claims of
professionals, Allowed Other Priority Claims and Involuntary Gap Claims of trade
creditors who provided materials, services or goods between December 4, 1998 and
February 12, 1999, will be paid in full, in Cash on the later of the Effective
Date and the date such Claim becomes an Allowed Claim, or as soon thereafter as
is practicable. Allowed Priority Tax Claims will be paid in full, in Cash on the
later of the Effective Date and the date such Priority Tax Claim becomes an
Allowed Priority Tax Claim, or as soon thereafter as is practicable.


                                      -5-
<PAGE>   11


         Other Allowed Secured Claims will either be (a) paid, at the sole
option of the Creditors' Committee, in full, in Cash on the later of the
Effective Date and the date such Secured Claim becomes an Allowed Secured Claim,
or as soon thereafter as is practicable, (b) will retain the Lien (or
replacement Lien) until full and final payment of such Allowed Secured Claim, at
which time such Lien shall be deemed null and void and shall be unenforceable
for all purposes; (c) receive the collateral securing its claim in satisfaction
of its secured claim.

         The remaining portion of the Secured Arnos Claim shall be satisfied by
the payment of remaining interest on its claim for the period December 1, 1999
through December 13, 1999 in Cash on the later of the Effective Date or the date
such Claim becomes an Allowed Claim, or as soon thereafter as is practicable.
Holders of Allowed Class 6 Claims will receive their pro rata share of (i) NEG's
cash, Arnos Corp. sale proceeds and related assets contributed to the Creditors
Trust created for the benefit of holders of Allowed Claims and Classes 1-6 have
been paid or provided for. The Creditors Committee has the right at that point
to sell the remaining assets of the Debtors or sell the rights of Noteholders to
retain in the form of Additional Common Stock the rights to receive between 49%
and 95% of all outstanding stock of the reorganized debtor on a fully diluted
basis to a third party or parties. The Noteholders shall have the right to elect
all members of the board of directors for NEG for a two (2) year term after the
Plan's Effective Date. Acting on behalf of the Class 6 Noteholders, they provide
the Creditors Committee the right to negotiate and sell such 49%-95% of fully
diluted Common Stock (available for distribution as Additional Common Stock) to
a third party or parties at any time before the Confirmation Date and thirty
(30) days following the Plan's Effective Date.


                                      -6-
<PAGE>   12


         Allowed Convenience Claims will receive on the later of the Effective
Date and the date such Convenience Claim becomes an Allowed Convenience Claim,
or as soon thereafter as is practicable, payment in Cash in the full amount of
such Allowed Convenience Claim.

         Allowed Class 5 Trade Claims incurred pre-December 4, 1998 will be
satisfied by distribution made from the Creditors' Trust to the holders of such
Allowed Trade Claims equal to seventy percent (70%) of such Allowed Claim,
provided all such Allowed General Unsecured Trade Claims do not exceed
$1,500,000 ("Trade Cap"). To the extent the aggregate of such Class 5 Allowed
Trade Claims exceeds $1,500,000, they will be treated as Allowed Class 6 Claims.

         Finally, with respect to the Equity Interests in the Debtors, all
existing NEG Equity Interests will remain in existence, except that all NEG
preferred stock will be converted into Common Stock at the conversion price of
$.25 per share. In the event the Creditors Committee elects to maximize the
return to Class 6 Note Claims by causing the Remaining Assets of the Debtors to
be liquidated, the Debtors will also be liquidated and/or wind up their
corporate affairs. The Creditors Trust will receive such liquidation proceeds
and distribute them in accordance with the terms of the Plan.

                                       IV.

                     SUMMARY OF CLASSIFICATION AND TREATMENT

         The Plan designates eight (8) Classes of Claims and Equity Interests
taking into account their differing nature and priority as established under the
Bankruptcy Code. The following is a summary of the Classes, Claims and Equity
Interest types, and the treatment of Allowed Claims and Allowed Equity Interests
under the Plan. The Debtors have prepared the following chart in an effort to
provide holders of Claims and holders of Equity Interests with the Debtors'
estimates of the expected outstanding amounts due owing with respect to each
Class of Claims as of the projected Confirmation Date, November 1, 1999. The
calculations, percentages and amounts set forth below are estimates which shall
not affect the obligations of any party under the Plan.

                       VOTING PROCEDURES AND REQUIREMENTS

         A.       BALLOTS AND VOTING DEADLINE.

         ONLY HOLDERS OF IMPAIRED CLAIMS IN CLASSES 3,4, AND 7 UNDER THE
         PLAN ARE BEING SOLICITED TO VOTE TO ACCEPT OR REJECT THE PLAN.

         The Claims classified in Classes 1, 2, 3 and 4 and the Equity Interests
classified in Class 8 are UNIMPAIRED under the Plan. Therefore, no votes on the
Plan are being solicited from the holders of Claims and Equity Interests in such
Classes pursuant to Section 1126(f) of the Bankruptcy Code.

         The Claims classified in Classes 4, 5, 6 and the Preferred Stock
Interests classified in Class 7 are IMPAIRED under the Plan. The holders of
Claims in Classes 4, 5, and 6 are being solicited to vote to accept or reject
the Plan. The holders of NEG Preferred Stock Interests in Class 7 are deemed to
have rejected the Plan and, therefore, are not being solicited to vote to accept
or reject the Plan.

         A ballot to be used for voting to accept or reject the Plan is enclosed
with this Disclosure Statement for those entitled to vote. The holder of a Claim
or Equity Interest, as the case may be, that is entitled to vote must (1)
carefully review the ballot and the instructions thereon, (2) complete and
execute the ballot, and (3) return the ballot to the address indicated thereon
by the deadline to enable the ballot to be considered for voting purposes. Any
ballot received by the Debtors that does not reflect an affirmative vote for
either the acceptance or rejection of the Plan will be deemed a vote for
acceptance of the Plan.

regard to your vote on the Plan. Votes cast by holders of Claims will be
irrevocable once received by the Creditors' Committee, unless the Bankruptcy
Court, after application, notice and hearing, permits a change of vote. If any
ballot received by the Creditors Committee is not discernible as to the Class of
the Claim or the name of the holder thereof, such ballot will be disregarded and
not counted. If a ballot is damaged or lost, please contact Creditors Committee
counsel. If you have any questions regarding the procedures for voting on the
Plan, please contact your legal counsel for advice.

         B. HOLDERS OF CLAIMS SOLICITED TO VOTE.

         Any holder whose Claim is within a Class impaired under the Plan and
who is eligible (upon Allowance of such Claim) to receive distributions under
the Plan, is being solicited to vote to accept or reject the Plan if either (i)
its Claim has been scheduled by the Debtors, but such Claim is not scheduled by
the Debtors as disputed, contingent or unliquidated, or (ii) it has filed a
proof of Claim (a) on or before June 21, 1999 (the "Bar Date"), or (b) after the
Bar Date with leave of the Bankruptcy Court pursuant to a Final Order, and as to
which no timely objection has been filed, or if a timely objection has been
filed, to the extent which such Claim is Allowed by a Final Order of the
Bankruptcy Court or temporarily Allowed for purposes of voting only. As of the
filing of this Disclosure Statement, the Creditors Committee are continuing to
review Claims to assess their validity and intend to identify objectionable
Claims and file objections thereto.

         Any Claim as to which an objection has been filed (and such objection
is still pending on the voting date) is not entitled to have its vote counted
unless the Bankruptcy Court temporarily allows the Claim for voting purposes in
an amount which the Bankruptcy Court deems proper upon motion by the holder to
whose Claim has been objected. Such a motion must be heard and determined by the
Bankruptcy Court prior to the date and time established by the Bankruptcy Court
for commencement of the Confirmation Hearing. In addition, a vote may be
disregarded if the Bankruptcy Court determines that such vote was not solicited
or procured in good faith, in accordance with the provisions of the Bankruptcy
Code.

         C. DEFINITION OF IMPAIRMENT.

         Under Section 1124 of the Bankruptcy Code, a class of claims or
interests is impaired under a plan of reorganization unless, with respect to
each claim or interest of such class, the Plan:

         1.   leaves unaltered the legal, equitable, and contractual rights of
              the holder of such claim or interest; or

         2.   notwithstanding any contractual provision or applicable law that
              entitles the holder of a claim or interest to receive accelerated
              payment of such claim or interest after the occurrence of a
              default:

              a.    cures any such default that occurred before or after the
                    commencement of the case under the Bankruptcy Code, other
                    than a default of a kind specified in Section 365(b)(2) of
                    the Bankruptcy Code;

              b.    reinstates the maturity of such claim or interest as it
                    existed before the default;

              c.    compensates the holder of such claim or interest for damages
                    incurred as a result of reasonable reliance on such
                    contractual provision or applicable law; and

              d.    does not otherwise alter the legal, equitable, or
                    contractual rights to which such claim or equity interest
                    entitles the holder of such claim or interest.

         D. Vote Required for Class Acceptance.

         As a condition of confirmation, the Bankruptcy Code requires acceptance
of a plan of reorganization by all impaired classes (except as discussed below).
The Bankruptcy Code defines acceptance of a plan by a class of claims as
acceptance by holders of two-thirds (2/3rds) in dollar amount and one-half (1/2)
in number of the claims of that class which actually cast ballots for acceptance
or rejection of the plan, i.e., acceptance takes place only if two-thirds
(2/3rds) in amount and majority in number of the holders of claims in a given
class actually voting cast their ballots in favor of acceptance. The Bankruptcy
Code defines acceptance of a plan by a class of equity interest.


                                      -14-
<PAGE>   20


holders as acceptance by holders of two-thirds in amount of the interests of
that class which actually cast ballots for acceptance or rejection of the plan.
Notwithstanding the requirement of class acceptance, a plan may be confirmed
even if one or more impaired classes does not accept the plan if at least one
impaired class of non-insider claims has accepted the plan and the Court
determines that the plan does not discriminate unfairly, and is fair and
equitable, with respect to each class that is impaired and has not accepted the
plan.

         If the Plan is confirmed, all holders of Claims against and Equity
Interests in the Debtors, whether voting or non-voting and, if voting, whether
accepting or rejecting the Plan, will be bound by the terms of the Plan.

                                       VI.

                            CONFIRMATION OF THE PLAN

         Under the Bankruptcy Code, the following steps must be taken to confirm
the Plan:

         A. CONFIRMATION HEARING.

         Section 1128(a) of the Bankruptcy Code requires the Bankruptcy Court,
after notice, to hold a hearing to determine whether all requirements for
confirmation of the Plan have been satisfied. By Order of the Bankruptcy Court
entered on April 17, 2000 the Confirmation Hearing has been scheduled for May
____, 2000, at ______ ___.m., Central Time, at the United States Bankruptcy

made at the Confirmation Hearing or any adjournment thereof.

         ANY ANNOUNCEMENT OF ADJOURNMENT OF THE DATE AND TIME OF THE
CONFIRMATION HEARING MADE IN COURT SHALL BE THE ONLY NOTICE PROVIDED TO HOLDERS

         B. REQUIREMENTS FOR CONFIRMATION OF THE PLAN.

         At the Confirmation Hearing, the Bankruptcy Court shall determine
whether the confirmation requirements of Section 1129 of the Bankruptcy Code
have been satisfied, in which event the


                                      -16-
<PAGE>   22


Bankruptcy Court shall enter an order confirming the Plan. The applicable
requirements for confirmation are as follows:

         1.   The Plan complies with the applicable provisions of the Bankruptcy
              Code.

         2.   The Creditors Committee has complied with the applicable
              provisions of the Bankruptcy Code.

         3.   The Plan has been proposed in good faith and not by any means
              forbidden by law.

         4.   Any payment made or promised by the Debtors or Creditors
              Committee, or by a person acquiring property under the Plan, for
              services or for costs and expenses in or in connection with the
              Chapter 11 Cases, or in connection with the Plan and incident to
              the Chapter 11 Cases, has been disclosed to the Bankruptcy Court,
              and any such payment made before the confirmation of the Plan is
              reasonable, or if such payment is to be fixed after confirmation
              of the Plan, such payment is subject to the approval of the
              Bankruptcy Court as reasonable.

         5.   The Creditors Committee has disclosed the identity and
              affiliations of any individual proposed to serve, after
              confirmation of the Plan, as a director, officer, or voting
              trustee of the Debtors, an affiliate of the Debtors participating
              in a Plan with the Debtors, or a successor to the Debtors under
              the Plan, and the appointment to, or continuance in, such office
              of such individual, is consistent with the interests of creditors
              and equity security holders and with public policy, and the
              Creditors Committee has disclosed the identity of any insider that
              will be employed or retained by the reorganized Debtors, and the
              nature of any compensation for such insider.

         6.   With respect to each Class of impaired Claims or Equity Interests,
              either each holder of a Claim or Equity Interest of such class has
              accepted the Plan, or will receive or retain under the Plan on
              account of such Claim or Equity Interest property of a value, as
              of the Effective Date of the Plan, that is not less than the
              amount that such holder would so receive or retain if the Debtors
              were liquidated on such date under Chapter 7 of the Bankruptcy
              Code; or if Section 1111(b)(2) of the Bankruptcy Code applies to
              the Claims of such Class, each holder of a Claim will receive or
              retain under the Plan on account of such Claim property of a
              value, as of the Effective Date of the Plan, that is not less than
              the value of such holder's interest in the Debtors' estates'
              interest in the property that secures such Claims.

         7.   Each Class of Claims or Equity Interests has either accepted the
              Plan or is not impaired under the Plan.


                                      -17-
<PAGE>   23
         8.   Except to the extent that the holder of a particular Claim has
              agreed to a different treatment of such Claim, the Plan provides
              that Allowed Administration Expense Claims and Allowed Other
              Priority Claims will be paid in full on the Effective Date and
              that Allowed Priority Tax Claims will receive on account of such
              Allowed Claims deferred cash payments, over a period not exceeding
              six years after the date of assessment of such Claim, of a value,
              as of the Effective Date, equal to the Allowed amount of such
              Claim.

         9.   At least one Class of Claims has accepted the Plan, determined
              without including any acceptance of the Plan by any insider
              holding a Claim of such Class.

         10.  Confirmation of the Plan is not likely to be followed by the
              liquidation, or the need for further financial reorganization, of
              the Debtors or any successor to the Debtors under the Plan, unless
              such liquidation or reorganization is proposed in the Plan.

         11.  The Plan must provide that the quarterly fees required under 28
              U.S.C. Section 1930 have been paid or that they will be paid on
              the Effective Date of the Plan.

         The Creditors Committee believes that the Plan satisfies all of the
statutory requirements of Chapter 11 of the Bankruptcy Code, that it has
complied or will have complied with all of the requirements of Chapter 11, and
that the proposal of the Plan is made in good faith. As to NEG Preferred and
Common Stock Interests, the Creditors Committee intends to seek confirmation of
the Plan under the cramdown provisions of the Bankruptcy Code discussed below.

         C. CRAMDOWN.

         Generally, under the Bankruptcy Code, a plan of reorganization must be
approved by each impaired class of creditors. A Bankruptcy Court, however, may
confirm a plan that has not been approved by each impaired class if at least one
impaired class accepts the plan by the requisite vote and the Bankruptcy Court
determines that the plan "does not discriminate unfairly" and is "fair and
equitable" with respect to each class that is impaired and has not accepted the
plan. A plan of reorganization does not discriminate unfairly within the meaning
of the Bankruptcy Code if each


                                      -18-
<PAGE>   24


dissenting class is treated equally with other classes of equal rank. "Fair and
equitable" has different meanings with respect to the treatment of secured
claims, unsecured claims and equity interests.

         As set forth in Section 1129(b)(2) of the Bankruptcy Code, the
condition that a plan of reorganization be fair and equitable with respect to a
class includes the following requirements. With respect to a secured claim,
"fair equitable" means either (i) the impaired secured creditor retains its
liens to the extent of its allowed claim and receives deferred cash payments at
least equal to the allowed amount of its claims with a present value as of the
effective date at least equal to the value of such creditor's interest in the
property securing its liens, (ii) property subject to the lien of the impaired
secured creditor is sold free and clear of that lien, with that lien attaching
to the proceeds of sale, and such lien proceeds must be treated in accordance
with clauses (i) and (iii) hereof, or (iii) the impaired secured creditor
realizes the "indubitable equivalent" of its claim under the plan.

         With respect to an unsecured claim, "fair and equitable" means either,
(i) each impaired unsecured creditor receives or retains property of a value
equal to the amount of its allowed claim, or (ii) the holders of claims and
interests that are junior to the claims of the dissenting class will not receive
any property under the plan.

         With respect to equity interests, "fair and equitable" means either (i)
each impaired equity interest receives or retains on account of such interest
property of a value equal to the greatest of the allowed amount of any fixed
liquidation preference to which such holder is entitled, any fixed redemption
price to which such holder is entitled, or the value of such interest; and (ii)
the holder of any interest that is junior to the interest of such class will not
receive under the plan any property on account of such junior interest.


                                      -19-
<PAGE>   25


         In the event one or more Classes of impaired Claims rejects the Plan,
the Creditors Committee reserves the right to proceed with confirmation pursuant
to Section 1129(b) of the Bankruptcy Code, and the Bankruptcy Court will
determine at the Confirmation Hearing whether the Plan is fair and equitable and
does not discriminate unfairly against any rejecting impaired Class of Claims.

                                      VII.

                           DESCRIPTION OF THE DEBTORS


         A. BUSINESS.

            1. GENERAL OVERVIEW OF THE COMPANY.

         National Energy Group, Inc. was incorporated under the laws of the

         a. Mid-Continent Area

         At July 1, 1999, approximately 52.5% (37.3 Bcfe) of the Company's
Proved Reserves were located in the Mid-Continent area in Oklahoma and western
Arkansas which includes the Anadarko and Arkoma Basins.

         b. Anadarko Basin.

         The Anadarko Basin is considered a mature oil and natural gas province
characterized by multiple producing horizons and relatively long reserve lives.
Drilling a Producing Well on these locations can convert Proved Undeveloped
Reserves to Proved Developed Producing Reserves, and can provide additional PUD
locations on the Company's leasehold acreage.

         The Company's Anadarko Basin properties were initially drilled on 640
acre producing units. Industry has successfully demonstrated to Oklahoma
regulators that deeper wells in the Anadarko Basin will not efficiently drain
640 acres and have obtained authorization for increased density drilling on
smaller acreage units. Further, under the forced pooling rules in Oklahoma, even
if the Company is not the operator of the property for which increased density
drilling has been approved, the Company may propose to drill and operate
additional wells on the original production unit. Frequently this results in the
proposing party owning a larger portion of newly drilled wells because other
Working Interest owners may decline to participate.

         During the year ended December 31, 1998, the Company drilled 7 Gross
(2.4 Net) Development Wells in the Anadarko Basin of which 5 Gross (1.6 Net)
Development Wells were completed as commercially productive. The Company's wells
typically are completed in horizons


                                      -24-
<PAGE>   30


ranging in depth between 7,000 and 15,000 feet Since Chapter 11, the Company has
drilled no additional wells.

         c. East and West Texas Area

         At December 31, 1998 approximately 35.8% (25.4 Bcfe) of the Company's
Proved-Reserves were located in the East and West Texas area, including East
Texas and the Goldsmith Adobe Unit in West Texas.

         (1) East Texas.

         These reserves are found in the Cotton Valley formation and the Travis
Peak formation. The Cotton Valley formation is generally found at depths of
8,500 to 10,500 feet in the Company's area of interest. These properties produce
from low permeability reservoirs that generally contain relatively long life
natural gas reserves. A significant portion of the cost to complete Cotton
Valley wells is incurred due to the low permeability of interbedded sandstones
and shales, which requires large hydraulic fracture stimulation, typically of
multiple zones of the producing formation, to obtain the increased production
levels necessary to make such wells commercially viable. The Travis Peak
formation is generally found at a depth of 7,200 feet and principally contains
oil reserves.

         (2) Goldsmith Adobe Unit ("Gau").

         The Goldsmith Adobe Unit is in the Permian Basin in West Texas. The
Company owns approximately a 95% Working Interest in the GAU, which it operates.

         Originally the GAU was drilled on 40 acre spacing units. Previous
operators had drilled several wells on 20 acre spacing units and, based on the
results of this drilling and 20 acre spacing development on adjoining leases,
the Company began a drilling program in July 1994 to


                                      -25-
<PAGE>   31
develop the GAU on 20 acre spacing units. During 1998, the Company drilled and
completed as commercially productive, 4 Gross (3.8 Net) Development Wells on the
GAU.

         Typically, wells drilled by the Company in the GAU in 1998 were drilled
to depths between 5,600 and 6,000 feet into the Clearfork formation.

         d. Gulf Coast Area

         At July 11, 1999 approximately 11.7% (8.3 Bcfe) of the Company's Proved
Reserves were located in the Gulf Coast areas, principally in the Greater Bayou
Sorrel Area in Iberville Parish, Louisiana and at Mustang Island in offshore
Gulf of Mexico. The Company also has participated in exploratory activity in
various parishes throughout Southern Louisiana.

         e. Greater Bayou Sorrel Area.

         The Greater Bayou Sorrel Area is located approximately eighty miles
west of New Orleans, in Iberville Parish, Louisiana, in the Atchafalaya River
Basin. The target formations of the Company's exploration prospects in this area
range from approximately 11,000 to 14,000 feet and include the Marg Vag, Marg
Howeii, Camerina, Cib Haz, and Marg Tex zones. The topography of the surface is
river swamp and all work must be done with barge-mounted drilling rigs and
boats. Production platforms are mounted on pilings. The Company first
participated in the successful exploratory test of the Schwing #1 well in the
Company's East Bayou Sorrel prospect in January 1996. This discovery well was
drilled to a total depth of approximately 14,000 feet on the eastern flank of
the old Bayou Sorrel Field, which was discovered by Shell Oil Company in 1954.
The old Bayou Sorrel Field was drilled in the 1950s and 1960s, with a total of
87 wells drilled and produced in twenty-eight different horizons ranging in
depths from 7,000 to 11,100 feet. During 1997, the Company successfully drilled
and completed a second test well, the Schwing #2.


                                      -26-
<PAGE>   32


         During 1998, the Company drilled 2 Gross (1.2 Net) Exploratory Wells in
the Greater Bayou Sorrel area both of which were determined to be dry holes.
Also during 1998, the Company successfully drilled and completed 1 Gross (.8
Net) Development Well in the Greater Bayou Sorrel area.

         The Company has completed shooting, processing and interpreting, an
approximate 54 square mile 3-D seismic survey over the Greater Bayou Sorrel
Area. The Company has identified additional potential drilling locations for
prospects in this area through interpretation of the 3-D seismic data. The
Greater Bayou Sorrel Area has produced and continues to produce significant oil
and gas. Because of the difficult topography, very little seismic data had been
acquired prior to the Company's 3-D survey. The Company controls approximately
13,400 acres either by lease or option to lease, within the Greater Bayou Sorrel
Area.

         In March 1998, the Company acquired Fortune Natural Resources
Corporations interests in the East Bayou Sorrel field for approximately $4.5
million in cash.

         3. OIL AND NATURAL GAS RESERVES

         The estimated reserves and related future net revenues as of July 1,
1999 were prepared by the Company's outside engineers Netherland, Sewell &
Associates, Inc. All of the Company's reserves are located in the continental
United States. This reserve report was prepared using constant prices and costs
in accordance with the published guidelines of the SEC. The net weighted average
prices used in the Company's reserve report at July 1, 1999 were $20.065 per
barrel of oil, increasing through 12/31/99 and then decreasing to $17.610 per
barrel of oil on December 31, 2002 and $2.30 per MMBTU of gas on July 1, 1999
and increasing to a high of $3.06 on December 31, 1999 and then decreasing to
$2.57 on December 31, 2002. The estimation of


                                      -27-
<PAGE>   33


reserves and future net revenues materially affected by the oil and gas prices
used in preparing the reserve report.

         4. LEASEHOLD ACREAGE.

         The following table shows the approximate Gross and Net Acres in which
the Company had a leasehold interest as of July 31, 1999

</TABLE>


         5. Title to Oil and Natural Gas Properties.

         The Company has acquired interests in producing wells and undeveloped
acreage in the form of Working Interests, Royalty Interests, and overriding
Royalty Interests. To reduce the Company's financial exposure in any one
exploratory prospect, the Company often acquired less than 100% of the Working
Interest in a prospect.

         6. Control over Production Activities.

         The Company operated 394 of the 550 producing wells in which it owned
an interest as of December 31, 1998. The non-operated properties are operated by
unrelated third parties pursuant to operating agreements which are generally
standard in the industry. Significant decisions about operations regarding
non-operated properties may be determined by the outside operator rather


                                      -28-
<PAGE>   34
than by the Company. If the Company declines to participate in additional
activities proposed by the outside operator under certain operating agreements,
the Company will not receive revenues from, and/or will lose its interest in the
activity in which it declined to participate.

         7. MARKETS AND CUSTOMERS.

         The availability of a ready market for any oil and natural gas produced
by the Company and the prices obtained for such oil and natural gas depend upon
numerous factors beyond its control, including the demand for and supply of oil
and natural gas; fluctuations in production and seasonal demand; the
availability of adequate pipeline and other transportation facilities; weather
conditions; economic conditions; imports of crude oil; production by and
agreements among OPEC members; and the effects of state and federal governmental
regulations on the import, production, transportation, sale and taxation of oil
and natural gas. The occurrence of any factor that affects a ready market for
the Company's oil and natural gas or reduces the price obtained for such oil and
natural gas may adversely affect the Company.

         A large percentage of the Company's oil and natural gas sales are made
to a small number of purchasers. The Company normally sells its oil under six
month contracts. During 1996, Plains Marketing and Transportation accounted for
83% of the Company's oil sales, while Crosstex Energy and GPM Natural Gas
Corporation each accounted for 22% of the Company's natural gas sales. For the
year ended December 31, 1997, Plains accounted for 84% of the Company's oil
sales, and Crosstex and GPM accounted for 20W and 14%, respectively, of the
Company's natural gas sales. For the year ended December 31, 1998, Plains
accounted for 85% of the Company's oil sales, and Crosstex and Aquila Energy
Marketing accounted for 23% and 26%, respectively, of the Company's natural gas
sales. The agreement with Plains, entered into in 1993, provides for Plains


                                      -29-
<PAGE>   35
to purchase the Company's oil pursuant to West Texas Intermediate posted prices
plus a premium. The Company does not believe that the loss of any purchaser
would have a material adverse effect on its business because, under prevailing
market conditions, such purchaser could be replaced.

         A portion of the Company's natural gas production has been sold in the
past pursuant to long term netback contracts. Under netback contracts, gas
purchasers buy gas from a number of producers, process the gas for natural gas
liquids, and sell the liquids and residue gas. Each producer receives a fixed
portion of the proceeds from the sale of the liquids, and residue gas. The gas
purchasers pay for transportation, processing, and marketing of the gas and
liquids, and assume the risk of contracting pipelines and processing plants in
return for a portion of the proceeds of the sale of the gas and liquids.
Generally, because the purchasers are marketing large volumes of hydrocarbons
gathered from multiple producers, higher prices may be obtained for the gas and
liquids. A portion of the Company's natural gas production is also sold under
forward sales contracts. See Note 9 of Notes to Consolidated Financial
Statements. Deliveries under these contracts are priced based on NYMEX prices
less a differential whereby the Company may fix the price for deliveries under
these contracts at any time three days prior to the close of the then current
contract based on the NYMEX prices at that time. The Company pays the cost of
transportation of the natural gas to the delivery point specified in these
contracts. The remainder of the Company's natural gas is sold on the spot market
under short-term contracts.

         8. OFFICE SPACE.

         The Company leases approximately 25,000 square feet of office space in
Dallas, Texas. The Company also leases a small amount of office space in Odessa,
Texas, Fort Smith, Arkansas and Yukon, Oklahoma for its business activities.


                                      -30-

<PAGE>   36
                  9.       EMPLOYEES.

                  In late 1999, the Company had approximately 50 full-time
employees. Of these employees, eight are field-related personnel. The Company
does not have any collective bargaining agreements with employees and believes
that relations with its employees are generally satisfactory.

                  10.      LEGAL PROCEEDINGS.

                  The Company filed suit against Mr. R.E. Steakley in August
1995 to enjoin Mr. Steakley from interfering with the operations of the Company.
Mr. Steakley counterclaimed against the Company for surface damages, alleging
certain environmental claims. In February 1999, without admitting any liability,
the Company and Mr. R.E. Steakley entered into a Settlement and Release
Agreement which provided that each of the Company and Mr. Steakley release and
discharge the other from all claims and damages which may have occurred through
January 31, 1999 and dismiss the pending lawsuits against each other. The
Company further agreed to pay Mr. Steakley an amount of $75,000, purchase
certain materials from Mr. Steakley at market value which the Company shall use
to maintain roads incidental to its operations on the Steakley property and
limit the Company's ingress and egress to specified entrances on the Steakley
property.

                  Other than the Bankruptcy Court proceedings, the Company is a
defendant in one additional material pending legal proceedings that it
anticipates settling.

                  While the ultimate results of these proceedings cannot be
predicted with certainty, the Company does not believe that the outcome of these
matters will have a material adverse effect on the Company.



                                      -31-
<PAGE>   37
                  11.      ABANDONMENT COSTS.

         NEG is generally responsible for the costs associated with the plugging
of wells, the removal of facilities and equipment and site restoration on its
oil and gas properties, pro rata to its working interest. Historically, NEG has
provided for expected future abandonment liabilities by accruing for such costs
as a component of depletion, depreciation and amortization as production occurs.
Between $1 and $2 million in abandonment costs are anticipated to be incurred in
connection with transactions involving the sale or NEG divestiture of Lake
Mongoulois. Estimates of abandonment costs and their timing may change due to
many factors, including actual drilling and production results, inflation rates,
changes in abandonment techniques and technology and changes in environmental
laws and regulations.

                  If a sale of the Debtors' interest in the Lake Mongoulois
properties does not occur, the Creditors' Trust may seek to rescind the
acquisition of such properties from EEX Corp. or, alternatively recover damages
from EEX Corp., in a minimal amount to cover such plugging and abandonment
costs. EEX may assert defenses to any such litigation, such that the ultimate
outcome cannot be predicted.

                  Other plugging and abandonment costs will be assumed and paid
by Arnos Corp. except with respect to Mustang Island where the expected
production of which may carry such costs as part of its operations.

                  The Company and Creditors Committee have been in negotiations
with third parties relative to their acquiring NEG's interest in both Lake
Mongoulois and Mustang Island and the assumption of the related plugging and
abandonment costs. Two such parties have executed letters



                                      -32-
<PAGE>   38
of intent which are subject to negotiations, Court approval and consummation of
a finalized agreement.

         B.       SELECTED FINANCIAL INFORMATION.

                  1.       MARKET INFORMATION.

         The Company's Common Stock traded on the NASDAQ National market since
September 1, 1995 under the symbol 11NEGX11. On November 9, 1998, NASDAQ
notified the Company that its common stock would be delisted effective at the
close of business that day for failing to meet the net tangible asset test and
minimum bid price requirements set forth in NASD Marketplace Rules 4450(a)(3)
and 4450(a)(5). NASDAQ also advised the Company that its common stock was
immediately eligible for trading on the OTC Bulletin Board through authorized
broker-dealers who had been market makers in the Company's stock during the last
30-days. The Company contacted its OTC Market Makers to notify them of NASDAQ's
action and to facilitate future trading activity. The Company's common stock has
traded in 1999 on the OTC Bulletin Board under the symbol 11NEGXQ11.

                  a.       10-3/4% SENIOR NOTES DUE 2006 - APPROXIMATELY $165
                           MILLION OUTSTANDING.

                  In November 1996, the Company issued $100 million aggregate
principal amount of unregistered 10 3/4 Series A Notes due 2006. The net
proceeds of the Series A Notes of approximately $96.1 million were used to repay
approximately $62.0 million of borrowings under the predecessor to the credit
facility and to increase the Company's working capital. In 1997, the Series A
Notes were exchanged for the registered 10 3/4% Series B Notes due 2006 which
are substantially identical to the Series A Notes. Collectively, the Series A
Notes and



                                      -33-
<PAGE>   39

Series B Notes are referred to as the "Series A/B Notes." In August 1997, the
Company issued $65.0 million aggregate principal amount of its unregistered
10 3/4% Series C Notes. The net proceeds of the Series C Notes of approximately
$64.8 million were used to repay approximately $23.0 million of borrowings under
the Bank One Credit Facility, to fund that year's drilling program, and to
increase the Company's working capital. In December 1997, the Company exchanged
substantially all of the Series A/B Notes and the Series C Notes for registered
10 3/4% Series D Notes due 2006. The Series D Notes are substantially identical
to the Series A/B Notes and the Series C Notes. Collectively, the Series A/B
Notes, the Series C Notes, and the Series D Notes are referred to as the
"Notes." The Notes bear interest at 10 3/4% per annum, payable semi-annually on
May 1 and November 1.

                  b.       ARNOS SECURED CLAIMS PURCHASE FROM BANK GROUP.

                  On August 29, 1996, the Company, NEG-OK and Boomer Marketing,
entered into a credit facility with Bank One, as Bank and Administrative Agent,
and the Credit Lyonnais New York Branch, as Bank and Syndication Agent
(collectively, the "Banks"). The credit facility consisted of a $100.0 million
reducing revolving line of credit, with an initial borrowing base of $60.0
million and a $5.0 million term loan. Interest under the reducing revolving line
of credit was payable monthly at the Bank One base rate, as adjusted. The
proceeds from the credit facility were used to repay a prior credit facility and
the existing indebtedness of NEG-OK, resulting in an extraordinary charge of
$292,372 or $.01 per common share in 1996.

                  In November 1996, the Company repaid the outstanding
borrowings under the credit facility with a portion of proceeds from the
issuance of $100.0 million principal amount of 10 3/4% Senior Notes due 2006
(the "Series A Notes"). 5.





                                      -34-
<PAGE>   40

                  Also in November 1996, in connection with the issuance of the
Series A Notes, the Company revised the credit facility. The credit facility had
a borrowing base of $25.0 million. The principal amount of borrowings was due at
maturity, August 29, 2000 and interest is payable monthly.

                  The Company granted liens to the Banks on substantially all of
the Company's oil and natural gas properties, whether currently owned or
thereafter acquired, and a negative pledge on all other oil and natural gas
properties. The credit facility required, among other things, semiannual
engineering reports covering oil and natural gas properties, and maintenance of
certain financial ratios, including the maintenance of a minimum interest
coverage, a current ratio, and a minimum tangible net worth.

                  The credit facility contained other covenants prohibiting cash
dividends, distributions, loans, or advances to third parties, except that cash
dividends on preferred stock will be allowed so long as no event of default
exists or would exist as a result of the payment thereof.

                  The Company was required to pay a commitment fee on the unused
portion of the borrowing base equal to 1% per annum.

                  On December 7, 1998, Bank one and Credit Lyonnais gave notice
to the Company that all outstanding obligations under the credit facility were
accelerated and were immediately due and payable due to certain unspecified
Events of Default as defined in the loan agreement. Effective December 22, 1998,
the credit facility and all associated liens were assigned by the Banks to
Arnos, Corp. ("Arnos") an affiliated subsidiary of the Company's Series D
Preferred Stockholder and entity controlled by Carl Icahn. In a letter dated
December 23, 1998 to the Company, Arnos (1) rescinded the acceleration of the
loan, (2) waived all defaults existing at that



                                      -35-

time and (3) made sufficient borrowings available to pay the interest on the
Senior Notes that was due on November 2, 1998 conditioned upon the Bankruptcy
Court's dismissal of the Involuntary Petition. The Company had $25,000,000
outstanding under the Arnos credit facility as of December 1, 1999.

                  In connection with its proposed purchase of substantially all
the oil and gas properties of NEG as of November 1, 1999, Arnos Corp. credit bid
under Section 363(k) of the Bankruptcy Code the $25 million of principal owed it
by NEG, leaving only approximately $100,000 in accrued interest to be paid to
Arnos Corp. on that debt.

                  c.       NEG PREFERRED STOCK.

                  In June 1994, the Company consummated the sale of $5.0 million
of the Series B Preferred Stock. Fifty thousand shares of the Series B Preferred
Stock were sold by the Company at $100 per share. The Series B Preferred Stock
is convertible into shares of the Common Stock at a conversion price of $1.625
per share. In October 1997, 13,813 shares of the Series B Preferred Stock were
converted into Common Stock, leaving 38,687 shares of the Series B Preferred
Stock outstanding. The board of directors declared dividends on the Series B in
December of 1998, which would be made in shares of Series B Preferred Stock.
That dividend-in-kind was not made and is currently in arrears.

                  In June 1995, the Company consummated the sale of $4.0 million
of the Series C Preferred Stock. Forty thousand shares of the Series C Preferred
Stock were sold by the Company at $100 per share. The Series C Preferred Stock
is convertible into shares of the Common Stock at a conversion rate of $2.00 per
share. The Series B Preferred Stock and Series C Preferred Stock require that
dividends be paid on the Series B Preferred Stock and Series C



                                      -36-
<PAGE>   42

Preferred Stock before any dividends are paid on the Common Stock. In October
1997, 17,000 shares of the Series C Preferred Stock were converted into Common
Stock, leaving 23,000 shares of the Series C Preferred Stock outstanding. The
board of directors declared dividends on the Series C in December of 1998, which
would be made in shares of Series C Preferred Stock. This dividend-in-kind was
not made and is currently in arrears.

                  In August 1996, the Company completed the sale of 100,000
shares of the Series D Preferred Stock for $10.0 million and 50,000 shares of
the Series E Preferred Stock for $5.0 million. The Series D Preferred Stock and
Series E Preferred Stock are convertible into shares of the Common Stock at a
conversion price of $2.25 per share. As part of such sale, the Company agreed to
extend the date at which it may first redeem the Series B Preferred Stock and
Series C Preferred Stock from June 14, 1997 to June 14, 1999. In October 1997,
40,500 shares of the Series E Preferred Stock were converted into Common Stock,
leaving 9,500 shares of the Series E Preferred Stock outstanding.

                  2.       SIGNIFICANT EVENTS OCCURRING DURING CHAPTER 11

         A number of significant events have occurred to National Energy Group,
Inc. and Boomer Marketing, Inc. since the filing of the involuntary petition in
bankruptcy against National Energy Group, Inc. on December 4 1998. The more
significant events include the following:

                  a.       GRANTING PETITIONING CREDITORS RELIEF AND DECLARING
                           NEG INSOLVENT.

                  At a hearing conducted before the Honorable Robert C. McGuire
on February 9, 1999, the Court after considering evidence, testimony and
arguments determined that the Company was not paying its debts as they generally
came due within the meaning of Section 303 of the



                                      -37-
<PAGE>   43

Bankruptcy Code, that an order for relief should be entered against the Company
and that the Company was insolvent.

                  b.       CESSATION OF MOST DRILLING ACTIVITIES.

                  On February 26, 1999, the Creditors Committee filed an
"Emergency Motion to Compel Debtors to Justify and Comply with Budget and to
Prohibit Future Drilling Activities in Chapter 11." Subsequently, the Company
agreed and the Court ordered that the Company discontinue exploratory or
development drilling programs commenced by it.

                  c.       TERMINATION OF THE EXCLUSIVE RIGHT TO FILE A PLAN OF
                           REORGANIZATION

         On April 2, 1999, the Creditors Committee filed a "Motion to Terminate
the Exclusive Right of the Debtors to File a Plan of Reorganization." At a
hearing conducted on April 22, 1999, the Court entered an order granting in part
and denying in part that motion by requiring the Company to file a comprehensive
summary plan of reorganization by the close of business on Monday, May 24, 1999
and for the Creditors Committee to submit an outline of a plan by the same date.
At subsequent hearings conducted before the Court on June 4, 1999 and
thereafter, the Company and the Creditors Committee agreed to a general
procedure for selling substantially all the oil and gas assets of the Company
through an auction to be conducted in the courtroom of and pursuant to sale
procedures approved by the Court. The Debtors did not to file a plan of
reorganization and disclosure statement, and as a consequence, its exclusive
right for doing so has expired.

                  d.       JOINT EMPLOYMENT OF CIBC WORLD CAPITAL MARKETS

         On July 30, 1999, the Company and the Creditors Committee jointly filed
an Application to Employ CIBC World Markets Corporation ("CIBC") as marketing
agent for the sale of the


                                      -38-
<PAGE>   44

more substantially valued oil and gas assets of the Company located in the
Arkoma and Anadarko Basins of Oklahoma, the East Texas and Gulf Coast fields of
Louisiana and Texas and the Company's Gau Unit in West Texas. The professionals
of CIBC worked with the land department, petroleum engineers, geologists,
financial and other personnel of the Company to develop a comprehensive
marketing brochure which was distributed to in excess of 400 industry parties,
announcing the intended sale of the Company's assets. The Company, together with
the assistance of PricewaterhouseCoopers and CIBC organized and oversaw the
operations of a data room, including visits of in excess of 30 companies
interested in purchasing all or sub-parts of the Company's oil and gas assets.
At an auction conducted before the Bankruptcy Court on November 1, 1999, Arnos
Corp.("Arnos") was determined to be the high bidder for substantially all the
oil and gas assets of the Debtors. Exco Resources, Inc. was determined to be the
back-up bidder.

                  e.       PROPOSED SALE TO ARNOS

         In connection with the November 1, 1999 auction sale, Arnos deposited
with Bank One, Texas as escrow agent for that auction sale, $9,250,000, to be
held pending a sale closing. Subsequently, Arnos indicated its desire to
negotiate with the Creditors Committee toward a consensual plan of
reorganization pursuant to which Arnos would either buy or end up controlling
all of NEG, including its common stock, intangible and other assets remaining
that were not sold as part of the November 1, 1999 auction sale. Pursuant to the
Court's directives, Arnos deposited into the Registry of the Court the sum of
$61,825,000 on or about December 9, 1999. As part of that registry deposit, the
Court permitted Arnos to credit bid pursuant to Section 363(k) of the Bankruptcy
Code $25,000,000 as the principal amount of its secured credit


                                      -39-
<PAGE>   45

facility purchased on December 22, 1998 from Bank One and Credit Lyonnais. As a
result, Arnos Corp. is left with only interest accruing on its debt from
December 1, 1999 through approximately December 13, 1999. As of the date of this
filing, the Creditors Committee and Arnos have yet to negotiate or finalize the
terms of a consensual plan of reorganization to address the Company's remaining
assets.


                  f.       EBCO AUCTION SALE OF NOMINALLY VALUED PROPERTIES

         In order to facilitate the auction sale and not complicate its process
with smaller and lesser valued and, in certain instances, non-contiguous
properties to those of the more highly valued assets, the Company and the
Creditors Committee filed a joint application to retain EBCO Auction Company and
include in its December, 1999 Oklahoma City, Oklahoma auction approximately 100
miscellaneous oil and gas assets of the Debtors. After accounting for offset,
secured and miscellaneous claims relating directly to those properties, the fee
commissions and other costs of sale, the net sale proceeds generated for the
benefit of creditors approximate $2.9 million.

                  3.       LIQUIDITY AND CASH RESOURCES FOR FUNDING PLAN

                  The following schedule sets forth the estimates of funds and
other assets on hand or available with which to pay Allowed Claims of creditors
under the Plan. This information, including an estimate of liabilities, was
compiled from information provided the Creditors' Committee by the Company:

                  5.      EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AND
                          CHANGE-IN-CONTROL ARRANGEMENTS


                  In January 1996, the Company executed an employment agreement
with Melissa H. Rutledge, Vice President, Controller and Chief Accounting
Officer, which has a term of three years from the effective date of a "change in
control" of the Company. In March 1997, April 1998 and June 1998, respectively,
the Company executed a similar employment agreement with Philip D. Devlin, Vice
President, General Counsel and Secretary; R. Kent Leuders, Vice President,
Corporate Development; Leslie J. Wylie, Vice President, Land, which has a term
of three years from the effective date of a "change of control" of the Company
(together with the above-referenced employment agreements, the "Employment
Agreements"). The Employment Agreements each provided that the three-year term
would continuously roll over (so that at any time during the term of such
agreements there is a remaining term of three years, but in no event beyond the
time the executive and/or officer reaches age 65).

                  The Employment Agreements defined the "change in control" to
have occurred when (i) a person, entity or group becomes the beneficial owner of
a majority of the securities of the Company ordinarily having the right to vote
for election of directors, (ii) during any connective two year period, the
directors at the beginning of the period (together with directors approved by a
vote of 66-2/3% of such initial directors plus directors previously approved by
such 66-2/3% margin) cease to constitute a majority of the Company's Board of
Directors, (iii) any sale, lease, exchange or transfer of all, or substantially
all, of the Company's assets occurs or (iv) a merger or consolidation occurs
with the effect that any person, entity or group, or the shareholders thereof,
become the owner of securities of the surviving corporation representing a
majority of the voting power of such surviving corporation for the election of
directors.


                                      -44-
<PAGE>   50

                  The Employment Agreements provided for a three year employment
term during which the executive and/or officer received for each year (i) 100%
of the average of the executive's annual base salary at the time in question and
the executive's annual base salary for each of the preceding two years, and (ii)
100% of the average of the bonuses paid to the executive and/or officer for
each of the preceding three fiscal years. If the executive and/or officer were
discharged without cause or resigns for "good reason" (as defined therein) after
a change in control, then in lieu of the compensation described in the
preceding sentence, the executive and/or officer claimed to be entitled to a
lump sum cash severance payment equal to three times the sum of (a) the
executive's annual base salary then in effect, (b) the average of cash bonuses
for each of the three previous years, and (c) the average of fully-vested
contributions to retirement plans for such executive and/or officer for each of
the three preceding year. In addition, at such time, all options and all other
retirement or pension contributions or benefits were to become fully vested and
remain fully exercisable for 360 days. Pursuant to an agreement with the Company
dated December 2, 1998, each of Ms. Rutledge, Mr. Devlin, Mr. Lueders and Ms.
Wylie agreed to terminate their existing Employment Agreements; provided that no
court (including the bankruptcy court) reduces or dismisses any of the Severance
Pay Benefits (described below) available to such executive pursuant to the
Company's Severance Policy.

                  6.       SEVERANCE POLICY.

                  While the Company was in default of its Notes, the Company's
directors initiated a Severance Policy effective November 23, 1998 for all
employees which provides that for a period ending October 31,2000, all Eligible
Participants would be entitled to a Severance Pay


                                      -45-
<PAGE>   51

Benefit up to 18 months (as defined in the Policy) in the event such Eligible
Participant was terminated by the Company for any reason other than "cause" (as
defined in the Policy). The Policy also provide that payments to such terminated
employee were to be subject to the employee's execution of a Separation
Agreement which would include the following provisions:

                  (i)      a release of all claims against the Company;

                  (ii)     a confidentiality provision; and

                  (iii)    an agreement to give notice to the Company and not
                           accept or retain any further Severance Pay Benefit in
                           the event the Eligible Participants were to accept
                           the same or substantially similar employment with any
                           other employer.

Payments under the Policy were to have been made to each such terminated
employee on a monthly basis; provided that in the event the Company was sold
pursuant to a merger or liquidation proceeding and the Eligible Participant was
not offered the same or substantially similar employment, such Severance Pay
Benefit would be paid to each Eligible Participant in a lump sum. To date, no
employees have been terminated by the Company who would be eligible for
Severance Pay Benefits under the Policy. Arnos has indicated to the Creditors
Committee that it is considering making a proposal either to pay this liability
or employ substantially all employees post-reorganization and thereby reduce
significantly the maximum estimated liability of $2.5 million.

                   FEDERAL INCOME TAX CONSEQUENCES OF THE PLAN

         THE DISCUSSION SET FORTH BELOW IS INCLUDED FOR GENERAL INFORMATION
ONLY. THE DEBTORS AND THEIR COUNSEL AND FINANCIAL ADVISORS ARE NOT MAKING ANY
REPRESENTATIONS REGARDING THE PARTICULAR TAX CONSEQUENCES OF CONFIRMATION AND
CONSUMMATION OF THE PLAN, WITH RESPECT TO THE DEBTORS, HOLDERS OF CLAIMS,
HOLDERS OF EQUITY INTERESTS, OR REORGANIZED DEBTORS, NOR ARE THEY RENDERING ANY
FORM OF LEGAL OPINION OR TAX ADVICE ON SUCH TAX CONSEQUENCES. THE TAX LAWS
APPLICABLE TO CORPORATIONS IN BANKRUPTCY ARE EXTREMELY COMPLEX, AND THE
FOLLOWING SUMMARY IS NOT EXHAUSTIVE. HOLDERS OF CLAIMS AND HOLDERS OF EQUITY
INTERESTS ARE STRONGLY URGED TO CONSULT THEIR TAX ADVISORS REGARDING TAX
CONSEQUENCES OF THE PLAN, INCLUDING FEDERAL, FOREIGN, STATE AND LOCAL TAX
CONSEQUENCES.


         A.       FEDERAL INCOME TAX CONSEQUENCES TO THE DEBTORS.

                  1.       GENERAL DISCUSSION.

         In general, the Creditors Committee does not expect the Debtors to
incur any substantial tax liability as a result of implementation of the Plan.
Based on the current state of the law and the facts known to Debtors the
Creditors Committee at this time, it is contemplated that the Plan


                                      -53-
<PAGE>   59

may permit the retention of a portion of the accumulated net operating loss
carryforwards ("NOLS") of the Debtors for future use if the Creditors Committee
elects to sell its rights to receive Additional Common Stock to a third party.
Accordingly, subject to the possible adjustment of the NOLs in connection with
future IRS examinations, and further subject to the limitations in the Tax Code
on the use of NOLs in calculating the alternative minimum tax ("AMT"), the NOLs
may be available to reduce at least a portion of the Debtors' future taxable
income.

                  2.       CANCELLATION OF INDEBTEDNESS.

         In general, the Tax Code, with certain exceptions, provides that
taxpayers that realize a "cancellation of indebtedness" must include the amount
of cancelled indebtedness in gross income to the extent that the indebtedness
canceled exceeds any consideration given for such cancellation. The Tax Code
further provides, however, that where the taxpayer is in a Chapter 11 case and
the cancellation of indebtedness is pursuant to a plan approved by the
bankruptcy court, such cancellation of indebtedness will not be included in
gross income, but the taxpayer must generally reduce tax attributes in a
specified order.

         The Debtors may realize a material amount of cancellation of
indebtedness ("COD") income as a result of the Plan. With certain exceptions, to
the extent that any creditor receives a distribution under the Plan in an amount
less than such creditor's Claim, the Debtor will realize COD income. Because the
Debtors are in bankruptcy, they will not be required to include COD income in
taxable income, but rather will be required to reduce their NOLs (and possibly
certain other tax attributes, including tax basis of assets) by the amount of
the COD income. Tax attributes must be reduced in the order specified as
follows: (i) NOLs, (ii) business credits,


                                      -54-
<PAGE>   60

(iii) minimum tax credits, (iv) capital loss carryovers, (v) tax basis in
assets, (vi) passive activity losses and credits, and (vii) foreign tax credit
carryovers. In lieu of this order, however, the Debtors may elect to apply any
portion of the reduction to reduce the basis of its depreciable assets first.

                  3.       NOLs AND FUTURE UTILIZATION.

         The total consolidated NOL carryforward available to the Debtors as of
December 31, 1999, is presently estimated to be approximately $90 million. The
foregoing amount, however, is only an estimate. It is not binding on the IRS and
is subject to adjustment as a result of future IRS audits of the Debtors' tax
returns, which may not take place for several years. Such losses are also
subject to reduction, as discussed in paragraph 2 above. It is expected that COD
realized by the Debtors pursuant to the Plan will subsequently reduce the
Debtors' NOLs and could reduce certain other tax attributes, including the tax
basis of assets.

         Section 382 (in conjunction with Section 383) of the Tax Code imposes
limitations upon the utilization of a corporation's NOLs, built-in losses and
credit carryforwards following significant changes in the corporation's stock
ownership, called an "ownership change." Issuance of Additional Common Stock
pursuant to the Plan may result in an "ownership change" as defined in Section
382 of the Tax Code. Thus, subject to certain exceptions applicable to Chapter
11 proceedings as discussed below, the Debtors' utilization of their NOLs
remaining after application of the COD rules described above (and also certain
"built-in losses") to reduce taxable income generated after the ownership change
may generally be subject to an annual limitation equal to the equity value of
the Debtors as a group multiplied by the Section 382 federal rate prescribed by
the IRS for the month in which the ownership change occurs.


                                      -55-
<PAGE>   61


         If the Debtors have a "net unrealized built-in loss" (excess of
aggregate adjusted tax basis of assets over aggregate fair market value of such
assets immediately before the ownership change) that exceeds certain thresholds,
such loss will be subject to the annual limitation to the extent it is
recognized during any of the first five years after the Effective Date. For
these purposes, in addition to recognized built-in losses resulting from the
disposition of these assets, any depreciation, amortization or depletion that is
deductible during the five year period and attributable to the built-in loss
existing on the Effective Date is treated as a recognized built-in loss subject
to these rules. If a deduction for any portion of a recognized built-in loss is
disallowed, such portion is carried forward. Accordingly, the utilization of any
portion of the Debtors' built-in loss (including depreciation deductions
attributable thereto) that is recognized during the five year period will be
subject to limitation under Section 382.

         Section 382(1)(5) of the Tax Code and the regulations thereunder
provide that the foregoing limitations on the utilization of NOLs after an
ownership change do not apply if (i) immediately before the ownership change,
the loss corporation is under the jurisdiction of a court in a Title 11 or
similar case, (ii) the transaction resulting in such ownership change is ordered
by the court or is pursuant to a plan approved by the court, and (iii) the
pre-change shareholders and "qualified creditors" of the loss corporation
determined immediately before the ownership change own in the aggregate 50% or
more of the value and voting power of the reorganized corporation after the
ownership change. Qualified creditors are creditors who held their indebtedness
for at least 18 months before the date of the filing of the title 11 case or who
hold debt that arose in the ordinary course of the trade or business if such
other creditors have, at all


                                      -56-
<PAGE>   62

times, been the beneficial holders thereof. The taxpayer may elect not to have
Section 382(l)(5) apply.

         If Section 382(1)(5) applies then the NOLs must be computed as if no
deduction had been allowed for interest paid by the corporation on any
obligations that were exchanged for stock pursuant to the plan during any
taxable year ending during the three-year period preceding the taxable year in
which the ownership change occurs. However, if an ownership change to which
Section 382(l)(5) applied were to occur pursuant to the Plan, the NOLs and other
tax attributes of the Debtors would be eliminated in their entirety if there
were a second ownership change during the two-year period following the date of
the ownership change pursuant to the Plan.

         The Reorganized Debtors can determine whether the requirements of
Section 382(1)(5) have been satisfied and, if so, whether to elect to have
Section 382(l)(5) not apply. Whether Section 382(l)(5) or Section 382(l)(6)
applies to the Plan, however, it appears that the application of Section 382
will limit the future use of the Debtors' remaining NOLs.

                  4.       ALTERNATIVE MINIMUM TAX.

         A corporation may be subject to the AMT even if its regular taxable
income is entirely offset by NOL carryforwards. For purposes of computing a
taxpayer's regular federal tax liability, all of the income recognized in a
taxable year may be reduced by NOL carryovers. For purposes of the AMT, however,
only 90% of a taxpayer's alternative minimum taxable income ("AMTI") may be
reduced by NOL carryovers ("AMTNOL carryovers"), the amount of which is
determined separately from the amount of regular NOL carryovers. Therefore, any
alternative minimum taxable income recognized by the Debtors will be taxable at
a rate of at least 2% (10% of the 20% AMT tax rate). Moreover, the Debtors' AMTI
(after certain adjustments and without



                                      -57-
<PAGE>   63

taking into account any deduction for AMTNOL carryovers) may be subject to a
 .12% environmental tax under Section 59A of the Tax Code.

         B.       FEDERAL INCOME TAX CONSEQUENCES TO HOLDERS OF CLAIMS.

                  1.       REALIZATION AND RECOGNITION OF GAIN OR LOSS IN
                           GENERAL.

         Generally, the holder of an Allowed Claim will realize a gain or loss
on the exchange of his Allowed Claim for the consideration received by the
holder under the Plan. The amount of realized gain will be equal to the
difference between (a) the sum of the amount of any Cash, and the fair market
value (generally issue price in the case of debt obligations received under the
Plan) of other consideration received (including Additional Common Stock) and
(b) the adjusted basis of the Allowed Claim exchanged therefor. (The adjusted
basis would generally be equal to the amount paid for the Allowed Claim,
increased by any amounts previously accrued as original issue or market
discount, and reduced to the extent that a bad debt deduction has been claimed
for federal income tax purposes with respect to the Allowed Claim.) However,
whether such realized gain or loss will be recognized (i.e., taken into account)
for federal income tax purposes will depend in part upon whether such exchange
qualifies as a "recapitalization" as defined in the Tax Code. Furthermore, even
if the exchange constitutes a recapitalization, it will nevertheless be fully
taxable unless the Claim exchanged is classified as a "security" for federal
income tax purposes and any note received in the exchange may be treated for
this purpose as if it were cash unless such note also constitutes a "security"
for federal income tax purposes.

         The term "security" is not defined in the Tax Code or the Regulations.
Whether a debt instrument constitutes a "security" depends on an overall
evaluation of the facts and circumstances surrounding the nature of the debt
instrument, with the term of the debt instrument


                                      -58-
<PAGE>   64

usually regarded as the most important factor. In general, the longer the term
of an instrument, the greater the likelihood that it will be considered a
security. As a rule of thumb, a corporate debt obligation evidenced by written
instruments having a term often or more years, when issued, will be classified
as a security, and an instrument having an original maturity of five years or
less, or arising out of the extension of trade credit, will not. Debt
instruments having a term of between five years and ten years are often treated
as securities, but may not be, depending on all the relevant factors.

         The Creditors Committee expresses no view with respect to whether
Claims or any new obligations exchanged therefor constitute securities for tax
purposes. Each holder of a Claim is urged to consult such holder's own tax
advisor in this regard.

         Under current law, if the terms of an obligation are significantly
modified, the modified obligation may be treated for federal income tax purposes
as a new obligation issued in exchange for the original obligation. Thus,
modifications to certain holder's Claims under the Plan, if treated as
significant, could cause such holder to be treated for federal income tax
purposes as receiving new obligations in exchange for the Debtors' original
obligations. However, the Creditors Committee expresses no view with respect to
whether any particular holder will be so treated. Each holder is urged to
consult such holder's own tax advisor in this regard. Each holder is also urged
to consult such holders own tax advisor as to the treatment of any new
obligations under the original discount rules.

         2.       HOLDERS OF CLAIMS WHOSE ALLOWED CLAIMS CONSTITUTE SECURITIES.

         The exchange of securities for stock and/or securities pursuant to the
Plan will likely constitute a recapitalization for federal income tax purposes.
As such, holders of Claims whose


                                      -59-
<PAGE>   65

Allowed Claims constitute securities (as defined for federal income tax
purposes) generally will not recognize gain or loss to the extent that their
securities are exchanged in part for Additional Common Stock and/or debt
obligations constituting securities. Such creditors will, however, recognize
gain to the extent of cash and the value (generally issue price in the case of
debt obligations) of other property received (e.g., any debt obligations that do
not constitute securities).

         The tax basis of stock and/or securities received in exchange for
securities will equal the exchanging holder's tax basis in the surrendered
securities increased by the amount of any gain recognized on the exchange, and
decreased by cash and the fair market value of any other consideration received.

                  3.       HOLDERS OF CLAIMS WHOSE ALLOWED CLAIMS DO NOT
                           CONSTITUTE SECURITIES.

         A holder of a Claim who exchanges an Allowed Claim that does not
constitute a security will recognize gain or loss on the exchange in an amount
equal to the difference between the holder's tax basis in the Allowed Claim and
the amount realized on the exchange. For tax purposes, the amount realized will
be the amount of Cash received, if any, plus the fair market value of any stock
or other property received (in the case of debt obligations received, generally
the issue price of such obligations). The tax basis of property received will be
the fair market value of such property on the date of exchange, and the holding
period for such property will begin on the day following such date.


                                      -60-
<PAGE>   66
                  4.       CHARACTER OF GAIN OR LOSS.

         In general, except for market discount discussed below, and except to
the extent that a bad debt deduction has been claimed (with corresponding tax
benefit) with respect to the Allowed Claims, any gain or loss recognized on the
exchange will be capital gain or loss if the Allowed Claims were capital assets
in the hands of a holder, and such gain or loss will be long-term capital gain
or loss if such holder's holding period for the Allowed Claim surrendered
exceeds one year at the time of the exchange. However, it should be noted that
Section 582(c) of the Tax Code provides that the sale or exchange of a bond,
debenture, note or certificate, or other evidence of indebtedness by a bank or
certain other financial institutions, shall not be considered the sale or
exchange of a capital asset. Accordingly, any gain recognized by such holders of
Claims as a result of the implementation of the Plan will be ordinary income,
notwithstanding the nature of their Allowed Claims.

         Under current law, net long-term capital gains of individuals are
subject to a maximum federal income tax rate of 20% (not taking into account any
phaseout of personal exemptions and certain itemized deductions), whereas the
maximum federal income tax rate on ordinary income (and net short-term capital
gains) of an individual is currently 39.6% (not taking into account any phaseout
of personal exemptions and certain itemized deductions). For corporations,
capital gains and ordinary income are taxed at the same maximum rate of 35%.
Capital losses are currently deductible only to the extent of capital gains
plus, in the case of taxpayers other than corporations, $3,000 of ordinary
income. In the case of individuals and other noncorporate taxpayers, capital
losses that are not currently deductible may be carried forward to other years,
subject to certain limitations. In the case of corporations, capital losses that
are not currently


                                      -61-
<PAGE>   67

deductible may generally be carried back to each of the three years preceding
the loss year and forward to each of the five years succeeding the loss year,
subject to certain limitations.

                                       IX.

                           BANKRUPTCY CAUSES OF ACTION

         A.       PREFERENCES.

         Pursuant to the Bankruptcy Code, a debtor may recover certain
preferential transfers of property, including cash, made while insolvent during
the ninety (90) days immediately prior to the filings of its bankruptcy petition
in respect of pre-existing debts to the extent the transferee received more than
it would have in respect of the pre-existing debt had the debtor been liquidated
under chapter 7 of the Bankruptcy Code. The recovery period is one year if the
recipient of the preferential transfer is an insider of the debtors. There are
certain defenses to such recoveries. Transfers made in the ordinary course of
the debtor's and the transferee's business according to the ordinary business
terms in respect to debt less than ninety (90) days old are not recoverable.
Furthermore, if the transferee extended credit subsequent to the transfer (and
prior to the commencement of the bankruptcy case) for which transferee was not
repaid, such extension constitutes an offset against any otherwise recoverable
transfer of property. If a transfer is recovered by the debtor, the transferee
has a general unsecured claim against the debtor to the extent of the recovery.
The Creditors Committee is continuing to review the payments made during the
ninety (90) days prior to the Commencement Date to creditors and during the one
(1) year prior to the Commencement Date to Insiders to determine whether the
Debtors should seek recovery of any such payments under Section 547 of the
Bankruptcy Code. The Creditors Committee's review is not yet complete, and
therefore, the Creditors Trust



                                      -62-
<PAGE>   68

reserves the right to commence an avoidance action under Sections 547 and 550 of
the Bankruptcy Code against any creditor or Insider that received a payment from
the Debtors during the ninety (90) days or one (1) year, respectively, prior to
the Commencement Date.

         B.       FRAUDULENT CONVEYANCES.

         Under the Bankruptcy Code and under various state laws, a debtor may
recover certain transfers or property, including the grant of a security
interest in property, made while insolvent or which rendered it insolvent if and
to the extent the debtor received less than fair value for such property. The
Creditors Committee is continuing to review all transfers or transactions that
may constitute fraudulent transfers to determine whether the Creditors Trust
should seek recovery of any such payments or transfers under Section 548 of the
Bankruptcy Code.

         C.       D&O AND RELATED LITIGATION.

         The Creditors Committee and/or the creditors will evaluate whether
claims the Debtors may have against former and present officers and directors
and auditors exist and have merit. The rights to bring such causes of action are
being conveyed to the Creditors' Trust which will be responsible for final
evaluation and, if deemed appropriate, filing, prosecution and/or settlement.
The Creditors Committee has already notified the Debtors that such causes of
action may exist.

                                       X.

                        ALTERNATIVES TO CONFIRMATION AND
                            CONSUMMATION OF THE PLAN

         The Creditors Committee believes that the Plan affords the holders of
Claims and Equity Interests the potential for the greatest realization on their
Claims and Equity Interests and,


                                      -63-
<PAGE>   69

therefore, is in the best interest of such holder. If the Plan is not confirmed,
however, the theoretical alternatives include: (a) continuation of the pending
Chapter 11 Cases; (b) alternative plans of reorganization; or (c) liquidation of
the Debtors under Chapter 7 of the Bankruptcy Code.

         A.       CONTINUATION OF THE CHAPTER 11 CASES.

         If the Debtors remain in Chapter 11 and the Plan as currently proposed
is not confirmed within the time period projected, the Debtors could continue to
operate their business and manage their properties as debtors-in-possession. The
value of assets and cash flow would be affected by the expenses of operating
under the jurisdiction of the Bankruptcy Court for an extended period of time.
Such delay would, therefore, in all probability, significantly reduce the
recoveries received by Creditors and Equity Interest holders under any future
plan or reorganization.

         B.       ALTERNATIVE PLANS OF REORGANIZATION.

         If the Plan is not confirmed, it is possible that another party in
interest in the Chapter 11 Cases could attempt to formulate and propose a
different plan or plans on such terms as they may desire. Such alternative plan
would still have to meet the requirements of confirmation.

         C.       CHAPTER 7 LIQUIDATION.

         If no plan can be confirmed, the Debtors' Chapter 11 Cases may be
converted to cases under Chapter 7 of the Bankruptcy Code. A business undergoing
a Chapter 7 liquidation typically has no prospect of rehabilitation. In a
Chapter 7 case a trustee would be elected or appointed to liquidate the Debtors'
assets. The proceeds of the liquidation would be distributed


                                      -64-
<PAGE>   70

to the respective holders of Claims against the Debtors in accordance with the
priorities established by the Bankruptcy Code.

         In a Chapter 7 case, the amount distributed to unsecured creditors
depends upon the net estate available after all assets of the Debtors have been
reduced to cash. The cash realized from liquidation of the Debtors' assets would
be distributed in accordance with the priorities set forth in Section 507 of the
Bankruptcy Code. Claims entitled to priority under the Bankruptcy Code would be
paid in full before any distribution to general unsecured creditors. Whether a
bankruptcy case is one under Chapter 7 or Chapter 11, Administrative Expense
Claims, Professional Compensation and Reimbursement Claims, Involuntary Gap
Claims, Priority Tax Claims and Other Priority Claims are entitled to be paid in
cash and in full before general unsecured creditors receive any funds.

         If the Chapter 11 Cases were converted to ones under Chapter 7 of the
Bankruptcy Code, the present priority claims may have a priority lower than
priority claims generated by the Chapter 7 case, such as the Chapter 7 trustee's
fees or the fees of attorneys, accountants and other professionals the trustee
may engage. Conversion to Chapter 7, then, would create an additional layer of
priority claims, including significantly the additional fees of a Chapter 7
Trustee (3-5% of total assets) and the expenses of any professionals hired by
the Trustee.

         The Creditors Committee believes that liquidation under Chapter 7 would
result in a substantial diminution of the value of the estates to unsecured
creditors because of (i) the additional administrative expenses involved in the
appointment of a trustee, hiring of attorneys, accountants and other
professionals to assist such trustee and other additional expenses and claims,
some of which would be entitled to priority, that would arise by reason of the
liquidation;


                                      -65-
<PAGE>   71

and (ii) of the failure to realize the potential going concern value of the
Debtors' assets; and (iii) the lost returns on distributions delayed by at least
a year as a consequence of conversion to Chapter 7. As a result, the Creditors
Committee believes that all Creditors will receive more under the Plan than they
would receive in the event of a Chapter 7.

                                  ARTICLE III.
               TREATMENT OF CLASSES OF CLAIMS AND EQUITY INTEREST



         3.1 CLASS 1 - OTHER PRIORITY CLAIMS:

         (a) Impairment and Voting. Class 1 is unimpaired by the Plan.
Each holder of an Allowed Other Priority Claim is deemed to have accepted the
Plan and is not entitled to vote to accept or reject the Plan.


                                      -11-
<PAGE>   16


         (b) Treatment. Except to the extent that a holder of an Allowed Other
Priority Claim has been paid by the Debtors prior to the Effective Date or
agrees to a different treatment, each holder of an Allowed Other Priority Claim
shall receive Cash in an amount equal to such Allowed Other Priority Claim on
the later of the Effective Date and the date such Other Priority Claim becomes
an Allowed Other Priority Claim, or within ten (10) days thereof.

         3.2 CLASS 2 - SECURED ARNOS CLAIM:

         (a) Impairment and Voting. Class 2 is unimpaired by the Plan. The Arnos
Claim is not entitled to vote to accept or reject the Plan.

         (b) Treatment. The remaining unpaid portion of Arnos Secured Claim that
equals the accrued interest due thereon from December 1, 1999 through December
13, 1999 will be paid in full on the later of the Effective Date, the date that
the Arnos Secured Claim becomes an Allowed Claim, or within ten (10) days
thereafter.

         3.3 CLASS 3 - OTHER SECURED CLAIMS:

         (a) Impairment and Voting. Class 3 Other Secured Claims are not
impaired and are not entitled to vote to accept or reject the Plan.

         (b) Treatment. At the option of the Creditors Committee or Creditors
Trust, as the case may be, Allowed Other Secured Claims will be satisfied in one
of the following manners:

                  (i) notwithstanding any contractual provisions or applicable
         laws that entitle the holder of an Other Secured Claim to demand or
         receive accelerated payment after the occurrence of a default, the
         legal, equitable and contractual rights to which the Claim entitles the
         holder thereof will be left unaltered and unimpaired. If applicable,
         any defaults that occurred before or after the Petition Date, other
         than defaults of the kind specified in Section 365(b)(2) of the
         Bankruptcy Code, will be cured on the Effective Date or as soon
         thereafter as is practicable; the maturity of such Claim shall be
         reinstated as it existed before such default; and the holder of such
         Claim shall be compensated for any damages incurred as a result of its
         reasonable reliance on such contractual provision or applicable law. In
         the alternative, at the option of the Creditors Committee or Creditors
         Trust, as the case may be, any Allowed Other Secured Claim may be
         satisfied in cash on the later of the Effective Date and the date such
         Claim is Allowed, or as soon thereafter as is practicable, in an amount
         equal to the Allowed Claim, provided that the aggregate amount of all
         Other Secured Claims which the Creditors Committee and Creditors Trust
         elect to satisfy in such manner shall not exceed $200,000 without the
         consent of the Creditors' Committee;

                  (ii) the collateral securing a particular Allowed Other
         Secured Claims will be abandoned to the holder of the Claim on the
         Effective Date or as soon thereafter as is practicable;


                                      -12-
<PAGE>   17


                  (iii) the Allowed Other Secured Claim will be paid in full in
         annual installments equal to the net cash flow attributable to the
         collateral which secures the Claim commencing on the first anniversary
         of the Effective Date, with final payment of all then-remaining amounts
         on the tenth anniversary of the Effective Date, with simple interest
         from the later of the Effective Date and the date such Claim is Allowed
         at the rate in effect under 26 U.S.C. Section 6621(b)(3) on the
         Confirmation Date unless the Bankruptcy Court determines that a
         different rate of interest should be used; or

                  (iv) such other treatment as the holder of the Other Secured
         Claim and the Creditors Committee or Creditors Trust, as the case may
         be, may otherwise agree.

                  Pursuant to Section 1111(b) of the Bankruptcy Code, if the
         Creditors Trust or Creditors' Committee elects to retain in the
         Creditors Trust or the Reorganized Debtor the collateral securing a
         non-recourse Other Secured Claim which is an Allowed Claim (and
         assuming the value of such collateral is not inconsequential), the
         holder of such Claim will be entitled to be treated as the holder of
         (x) an Other Secured Claim in an amount equal to the value of the
         Estate's interest in such collateral and (y) a General Unsecured Claim
         in an amount equal to the difference, if any, between the value of the
         Estate's interest in such collateral and the amount of such Allowed
         Claim, unless the application of Section 1111(b)(2) of the Bankruptcy
         Code is elected.

         3.4 CLASS 4 - CONVENIENCE CLAIMS:

         (a) Impairment and Voting. Class 4 is unimpaired by the Plan. Each
holder of an Allowed Convenience Claim is unimpaired and is not entitled to vote
to accept or reject the Plan.

         (b) Treatment. Except to the extent that an Allowed Convenience Claim
has been paid by the Debtors prior to the Effective Date or agrees to a
different treatment, each holder of an Allowed Convenience Claim as of the
Record Date shall receive Cash in an amount equal to 90% of such Allowed
Convenience Claim on the later of the Effective Date and the date such Allowed
Convenience Claim becomes an Allowed Convenience Claim, or within ten (10) days
thereof.

         3.5 CLASS 5 - TRADE CLAIMS (GENERAL UNSECURED CLAIMS):

         (a) Impairment and Voting. Class 5 is impaired by the Plan. Each
holder of an Allowed General Unsecured Claim (excluding Notes) is entitled to
vote to accept or reject the Plan.

         (b) Treatment. To the extent that holders of Allowed Trade Claims total
in the aggregate less than $1.5 million, then each holder of an Allowed Trade
Claim shall receive a Pro Rata Share equal to 70% of each such Allowed Trade
Claim; provided, however to the extent that the aggregate of Allowed Trade
Claims exceed $1.5 million, then such Class 5 Trade Claims shall be treated as
part of Class 6 Note Claims under Section 3.6 hereof.



                                      -13-
<PAGE>   18



         3.6 CLASS 6 - NOTE CLAIMS:

         (a) Impairment and Voting. Class 6 is impaired by the Plan. Each
Noteholder is entitled to vote to accept or reject the Plan.

         (b) Treatment. The Allowed Note Claims shall be the primary beneficiary
of the Creditors Trust. The Creditors Trust shall utilize the Cash, Arnos Escrow
Funds and any Proceeds recovered from prosecution of the Causes of Action
("Litigation Proceeds"), together with any proceeds received from the
liquidation of miscellaneous assets of the Debtor, to pay in the order of their
priority, Allowed Administrative Claims, Allowed Priority Claims, Allowed
Priority Non-Tax Claims, Allowed Convenience Claims, Allowed Other Secured
Claims and the Allowed Arnos Secured Claim ("Superior Claims"). After
establishing a sufficient reserve to cover Dispute Claims and an administrative
reserve to insure the continued viability and operation of the Trust, the
Creditor Trust shall make the Initial Distribution and any Subsequent
Distribution and Surplus Distribution to Norwest Bank, N.A., the Note Indenture
Trustee, which, in turn, shall immediately distribute such proceeds to the
holders of Allowed Note Claims on a Pro-Rata basis.

         (c) Additional Consideration to Class 6 Claims. In order to maximize
the recovery of Allowed Class 6 Note Claims, the Creditors Committee shall have
the right for a period of thirty (30) days following the latter of the entry
date of the Confirmation Order or the Effective Date, within which to dispose of
the remaining assets of the Debtors not otherwise specifically dealt with
herein, including, but not limited to, the corporate entity itself, goodwill,
net operating losses, Office Lease, furniture fixtures and equipment,
miscellaneous oil and gas assets (collectively the "Remaining Assets") in one of
two manners:

                  (i) First, to cause such Remaining Assets to be transferred,
         conveyed and assigned to the Creditors Trust for its liquidation, with
         the resulting proceeds to be distributed in accordance with the other
         provisions of this Plan. In that event, the Debtors shall be considered
         to be in the mode of a liquidation or be winding up their corporate
         affairs. To the extent necessary, the Creditors Committee may appoint
         one or more individuals, persons or entities to assume control of the
         winding up of the corporate affairs of the Debtors, including the
         Trustee of the Creditors Trust.

                  (ii) Second, and alternatively, the Creditors Committee may
         elect, within the above-described period of time, to cause the
         Reorganized Debtor to distribute to each holder of an Allowed Note
         Claim, determined as of the Record Date, such shares of Additional
         Common Stock as shall equal, in the sole discretion of the Creditors
         Committee, between 49% and 95% of then issued and outstanding Common
         Stock of the Reorganized Debtors, determined as of the Effective Date
         on a fully diluted basis (calculated after giving effect to the
         conversion of all series of Preferred Stock into Common Stock, as
         provided herein). To the extent that such distributions are, in fact,
         made, they shall be to the holders of Allowed Note Claims determined as
         of the Record Date and mailed to their addresses as they appear in the
         records of the Trustee under the Note Indenture. Prior to such
         distributions of Additional Common Stock, the Creditors Committee may
         sell, assign, or otherwise convey either the Remaining Assets or the
         rights to receive such Additional Common Stock to a third party


                                      -14-
<PAGE>   19


         or parties. The resulting proceeds received from the sale of such
         rights or Remaining Assets, as the case may be, shall be distributed by
         the Creditors Trust in accordance with the other terms of the Plan.

         (d) Right to Appoint Board of Directors. For a period of two years
after the Effective Date, the Creditors Committee, if then acting, and, if not,
then the Trust Committee or, in the alternative, if the Creditors Committee has
elected to issue Additional Common Stock to the holders of Allowed Senior Note
Claims or to sell such related rights to a third party or parties, then the
Creditors Committee or such third party or parties shall respectively have the
right to appoint all members of the Board of Directors of the reorganized
Debtors for such period of time.

         3.7 CLASS 7 - NEG PREFERRED STOCK:

         (a) Impairment and Voting. Class 7 is impaired by the Plan. Each holder
of Series B-E of NEG Preferred Stock is deemed to have rejected the Plan and
shall not be entitled to vote to support or reject the Plan.

         (b) Treatment. As of the Effective Date, each holder of NEG Preferred
Stock as of the Record Date shall be deemed to have converted their holdings of
Preferred Stock into NEG Common Stock on the assumed basis of NEG's Common Stock
being traded at 25 cents a share immediately prior to such conversion.

         3.8 CLASS 8 - NEG COMMON STOCK:

         (a) Impairment and Voting. Class 8 is impaired by the Plan. Each holder
NEG Common Stock is deemed to have rejected the Plan and is not entitled to vote
to accept or reject the Plan.

         (b) Treatment. Each holder of Common Stock as of the Record Date shall
retain its Common Stock in NEG.

                                   ARTICLE IV.
              TREATMENT OF IMPAIRED CLASSES OF CLAIMS AND INTERESTS

         4.1 Voting of Claims and Equity Interests. Each holder of an Allowed
Claim in an impaired Class of Claims shall be entitled to vote separately to
accept or reject the Plan as provided in such Final Order as is entered by the
Bankruptcy Court establishing certain procedures with respect to the
solicitation and tabulation of votes to accept or reject the Plan, or in any
other Final Order of the Bankruptcy Court.

         4.2 Nonconsensual Confirmation. If any impaired Class of Claims
entitled to vote shall not accept the Plan by the requisite statutory majorities
provided in Sections 1126(c) or 1126(d) of the Bankruptcy Code, as applicable,
the Creditors Committee reserves the right to amend the Plan or undertake to
have the Bankruptcy Court confirm the Plan under Section 1129(b) of the
Bankruptcy Code or both.

         4.3 Method of Distributions Under the Plan.

         (a) In General. Subject to Bankruptcy Rule 9010, all distributions
under the Plan shall be made by the Creditors Trust to the holder of each
Allowed Claim at the address of such holder as listed on the Schedules as of the
Record Date, unless the Creditors Trust has been notified in writing of a change
of address by such holder that provides an address for such holder different
from the address reflected on the Schedules (for holders of Allowed Claims). All
distributions under the Plan to holders of Notes with respect to their Allowed
Claims shall be made to Norwest Bank, N.A., indenture trustee of the Notes and
as disbursing agent for the holders of the Notes. Norwest Bank shall be entitled
to receive reasonable compensation for such efforts.

         (b) Distributions of Cash. Any payment of Cash made by the Creditors
Trust pursuant to the Plan shall be made, at the sole option of the Creditors
Trust, by check drawn on a domestic bank, wire transfer, or any other method
mutually agreeable between the Creditors Trust and the payee.

         (c) Timing of Distributions. Any payment or distribution required to be
made under the Plan on a day other than a Business Day shall be made on the next
succeeding Business Day.

         (e) Minimum Distributions. No payment of Cash less than one-hundred
dollars ($100.00) shall be made by the Creditors Trust to any holder of a Claim
unless a request therefor is made in writing to Creditors Trust.

         (f) Fractional Shares. No fractional shares of New NEG Common Stock or
Cash in lieu thereof shall be distributed under the Plan. When any distribution
on account of an Allowed Claim or Allowed Equity Interest pursuant to the Plan
would otherwise result in the issuance of a number of shares of New NEG Common
Stock that is not a whole number, the actual distribution of shares of New NEG
Common Stock shall be rounded as follows: (i) fractions of 1/2 or greater shall
be rounded to the next higher whole number, and (ii) fractions of less than 1/2
shall be rounded to the next lower whole number. The total number of shares
of New NEG Common Stock to be distributed to a Class of Claims or NEG Equity
Interests, as the case may be, shall be adjusted as necessary to account for the
rounding provided in this Section 4.3(f).

         (g) Distributions to Holders as of the Record Date. As of the close of
business on the Record Date, the claims register (for Claims) shall be closed,
and there shall be no further changes in the record holders of any Claims. The
Creditors' Trust and Reorganized Debtors shall have no obligation to recognize
any transfer of any Claims occurring after the Record Date. The Creditors' Trust
and Reorganized Debtors shall instead be entitled to recognize and deal for all
purposes under the Plan (except as to voting to accept or reject the Plan
pursuant to Section 4.1 of the Plan) with only those record holders stated on
either the Claims Register (for Claims) or Records of Norwest Bank, N.A. (for
Notes) as of the close of business on the Record Date.

         (h) Distribution Withheld for Disputed Claims.

                  (i) Establishment and Maintenance of Reserve. On the Initial
         Distribution Date and each Subsequent Distribution Date, the Creditors
         Trust shall reserve from the distributions to be made on such dates to
         the holders of Allowed Claims in a particular Class, an amount of Cash
         equal to 100% of the distributions to which holders of Disputed Claims
         in such Class would be entitled under the Plan as of such dates as if
         such Disputed Claims were Allowed Claims in their Disputed Claim
         Amounts (the "Reserve").

                  (ii) Cash Held in Reserve. Any dividends to be paid on with
         respect to NEG Claims held in the Reserve shall be deposited in a
         segregated bank account or accounts in the name of Creditors Trust and
         designated as held in trust for the benefit of holders of Disputed
         Claims to the extent such Disputed Claim is ultimately Allowed. Cash
         held in the Reserve shall not constitute property of the Reorganized
         Debtors. The Creditors Trust shall invest the Cash held in the Reserve
         in a manner consistent with investment guidelines, which investment
         guidelines shall be included in the Plan Supplement. The Creditors
         Trust shall pay, or cause to be paid, out of the funds held in the
         Reserve, any tax imposed on the Reserve by any governmental unit with
         respect to income generated by the property held in the Reserve. The
         yield earned on such invested Cash (net of applicable taxes) shall be
         held in trust for the benefit of holders of Disputed Claims to the
         extent such Disputed Claim is ultimately Allowed.

         (i) Distributions Upon Allowance of Disputed Claims. The holder of a
Disputed Claim that becomes an Allowed Claim subsequent to the Initial
Distribution Date shall receive distributions from the Reserve in accordance
with and pursuant to the terms of the Plan on the next Subsequent Distribution
Date selected by the Trust Committee during the Quarter that follows the Quarter
during which such Disputed Claim becomes an Allowed General Unsecured Claim
pursuant to a Final Order. Such distributions shall be made in accordance with
the Plan based upon the distributions that would have been made to such holder
under the Plan if the Disputed Claim had been an Allowed Claim on or prior to
the Effective Date, without any post-Effective Date interest thereon.

         (j) Surplus Distributions to Holders of Allowed General Unsecured
Claims. The following consideration shall constitute surplus distributions (the
"Surplus Distributions") pursuant to the Plan: (i) distributions under the Plan
to holders of Allowed Claims that are unclaimed for a period of one (1) year
after distribution thereof; and (ii) to the extent that a Disputed Claim is not
Allowed or becomes an Allowed Claim in an amount less than the Disputed Claim
Amount, the excess of the amount in the Reserve over the amount actually
distributed on account of such Disputed Claim. The Surplus Distributions shall
be distributed to the holders of Allowed Note Claims pursuant to the Plan;
provided, however, that the Creditors' Trust shall not be under any obligation
to make any Surplus Distributions on a Subsequent Distribution Date unless the
Cash to be distributed on a Subsequent Distribution Date aggregates $100,000 or
more, unless the distribution is the last distribution under the Plan.

         4.4 Objections to and Resolution of Administrative Expense Claims,
Claims and Equity Interests. Except as to applications for allowances of
compensation and reimbursement of


                                      -17-
<PAGE>   22



expenses under Sections 330 and 503 of the Bankruptcy Code, the Creditors
Committee or Creditors Trust shall have the exclusive right to make and file
objections to Administrative Expense Claims, Claims and Equity Interests
subsequent to the Confirmation Date. All objections shall be litigated to Final
Order; provided, however, that the Creditors Committee or Creditors Trust shall
have the authority to compromise, settle, otherwise resolve or withdraw any
objections, without approval of the Bankruptcy Court. Unless otherwise ordered
by the Bankruptcy Court, the Creditors Committee or Creditors Trust shall file
all objections to Administrative Expense Claims that are the subject of proofs
of Claim or requests for payment filed with the Bankruptcy Court (other than
applications for allowances of compensation and reimbursement of expenses),
Claims and Equity Interests and serve such objections upon the holder of the
Administrative Expense Claim, Claim or Equity Interest as to which the objection
is made as soon as is practicable, but in no event later than ninety (90) days
after the Effective Date or such later date as may be approved by the Bankruptcy
Court.

         4.5 Record Date for Distributions to Holders of Notes. At the close of
business on the Record Date, the transfer ledgers of Norwest Trust, as
indenture trustee, agent and servicer of the Notes, shall be closed and there
shall be no further changes in the record holders of the Notes. On or before the
Effective Date, Norwest Trust shall certify to the Creditors Trust or the
Reorganized Debtors the names and addresses of all holders of the Notes and the
face amount of the Notes held by them as of the Record Date. Norwest Trust, as
indenture trustee, agent and servicers of the Notes, and the Creditors Trust and
Reorganized Debtors shall have no obligation to recognize any transfer of Notes
occurring after the Record Date.

         4.6 Fees and Expenses of Norwest Trust. Notwithstanding anything to the
contrary contained in the Plan, any fees and expenses of Norwest Trust incurred
through the Effective Date with regard to any of the Notes, including reasonable

determined by the Bankruptcy Court in accordance with the standard for allowance

         5.1 Assumption or Rejection of Executory Contracts and Unexpired
Leases.

         (a) Executory Contracts and Unexpired Leases. Pursuant to Sections
365(a) and 1123(b)(2) of the Bankruptcy Code, all executory contracts and
unexpired leases entered into prior to the Commencement Date that exist between
the Debtors and any person shall be assumed or rejected (as set forth below) by

anything contained herein to the contrary, any executory contract or unexpired
lease (i) which has been assumed pursuant to a Final Order of the Bankruptcy
Court entered prior to the Confirmation Date, (ii) which has been rejected
pursuant to a Final Order of the Bankruptcy Court entered prior to the
Confirmation Date, or (iii) as to which a motion for approval of the rejection
of such executory contract or unexpired lease has been filed prior to the
Confirmation Date shall be rejected or assumed in accordance with such motion or
Final Order. Subject to the immediately preceding sentence, the executory
contracts and unexpired leases described below and identified in Exhibits to the
Plan or Disclosure Statement shall be deemed to be, respectively, assumed or
rejected as follows:

                  (i) Joint Assumed Operating Agreements. Any Joint Operating
         Agreements not sold to Arnos Corp. under the Purchase and Sale
         Agreement shall be assumed and be rejected, as indicated in exhibits or

         satisfactory agreement, regarding adequate assurance of future
         performance, all other Joint Operating or other similar Agreements that
         are not specifically listed in such exhibits or pleadings shall be
         deemed assumed.

                  (ii) Seismic Contracts. The Seismic Contracts specifically
         identified in Exhibit "A" shall be deemed rejected. All other Seismic
         Contracts shall be deemed assumed.

                  (iii) Oil and Gas Purchase Contracts. Any Oil and Gas Purchase
         Contracts not specifically identified and sold to Arnos Corp. under the
         Purchase and Sale Agreement shall be deemed rejected.

                  (iv) NEG Operating Agreements. All NEG Operating Agreements
         not sold to Arnos Corp. under the Purchase and Sale Agreement shall be

                  (v) Office Leases. The Office Lease shall be deemed assumed or
         rejected depending on whether the Creditors Committee sells the
         Miscellaneous Asset and/or Class 6 Noteholders' rights to receive
         Additional Stock to a third party or parties.

                  (vi) Farmout Agreements, Easements, and Surface Rights. All
         Farmout Agreements, Easements, and Surface Rights, to the extent that
         they constitute executory


                                      -19-

         contract and not sold to Arnos Corp. under the Purchase and Sale
         Agreement, shall be deemed assumed or rejected as indicated in the
         exhibits or pleadings filed by the Creditors Committee prior to the
         Confirmation Date.

                  (vii) Indemnification Agreements. All Indemnification
         Agreements of NEG shall be deemed rejected.

                  (viii) Notwithstanding the foregoing, any executory contract
         or unexpired lease not specifically rejected as heretofore provided
         (and not otherwise assumed or rejected), except as specifically
         identified in the exhibits or pleadings filed by the Creditors
         Committee prior to the Confirmation Date shall be deemed assumed.

                  (ix) To the extent that the holder of a Claim arising from the
         rejection of any contract, agreement or lease asserts a Secured Claim,
         the Debtors may file a motion under Section 506 of the Bankruptcy Code
         to limit the amount of such Secured Claim, an adversary proceeding to
         avoid the Security Interest taken for such Claim, and/or an objection
         to the Claim itself. To the extent such Claim is Unsecured, such Claim
         shall be treated as a General Unsecured Claim under Class 6 of the
         Plan.

                  (x) The listing of a document on exhibits or pleadings filed
         by the Debtors shall not constitute an admission by the Debtors or
         Reorganized Debtors that such document is an executory contract or an
         unexpired lease or that the Debtors or Reorganized Debtors have any
         liability thereunder.

         (b) Approval of Assumption or Rejection of Executory Contracts and
Unexpired Leases. Entry of the Confirmation Order shall constitute (i) the
approval, pursuant to Sections 365(a) and 1123(b)(2) of the Bankruptcy Code, of
the assumption of the executory contracts and unexpired leases assumed pursuant
to the Plan, (ii) the extension of time, pursuant to Section 365(d)(4) of the
Bankruptcy Code, within which the Debtors may assume or reject the unexpired
leases hereof through the date of entry of a Final Order approving the
assumption or rejection of such unexpired leases, and (iii) the approval,
pursuant to Sections 365(a) and 1123(b)(2) of the Bankruptcy Code, of the
rejection of the executory contracts and unexpired leases rejected pursuant to
the Plan.

         (c) Cure of Defaults. Except as may otherwise be agreed to by the
parties, within ninety (90) days after the Effective Date, the Reorganized
Debtors shall cure any and all undisputed defaults under any executory contract
or unexpired lease assumed pursuant to the Plan in accordance with Section
365(b)(l) of the Bankruptcy Code.

         (d) Bar Date for Filing Proofs of Claim Relating to Executory Contracts
and Unexpired Leases Rejected Pursuant to the Plan. Claims arising out of the
rejection of an executory contract or unexpired lease pursuant to the Plan must
be filed with the Bankruptcy Court and served upon the Debtors or Reorganized
Debtors, or as otherwise may be provided in the Confirmation Order, by no later
than thirty (30) days after the later of (i) notice of entry of an order
approving the rejection of such executory contract or unexpired lease, and (ii)

estates, the Reorganized Debtors and their property. Notwithstanding anything to
the contrary contained in the Plan, the Creditors Trust shall have until sixty
(60) days after a proof of Claim filed in accordance with this Article, to file
an objection to such Claim.

         5.2 Compensation and Benefit Programs. Except as otherwise provided in
the Plan, all employment and severance practices and policies, and all
compensation and benefit plans, policies, and programs of the Debtors applicable
to their directors, officers or employees, including, without limitation, all
savings plans, retirement plans, health care plans, severance benefit plans,
indemnity agreements, incentive plans, workers' compensation programs and life,
disability and other insurance plans are treated as executory contracts under
the Plan and are hereby rejected pursuant to Sections 365(a) and 1123 (b)(2) of
the Bankruptcy Code. Notwithstanding the foregoing, the "Stayput" Bonus and
Employee's Severance Programs approved by the Court by order dated September 7,
1999 shall be assumed and the benefits due thereunder shall be paid to the
designated recipients thereof by the Creditors' Trust. Any disputes as to the
entitlement to such payments by any employee shall be treated as a Disputed
Claim and resolved by the Court, after notice and hearing.

                            RETENTION OF JURISDICTION

         9.1 Jurisdiction. Until this Chapter 11 Case is closed, the Bankruptcy
Court will retain such jurisdiction as is legally permissible, including that
necessary to ensure that the purpose and intent of this Plan are carried out and
to hear and determine all Claims set forth herein that could have been brought
before the entry of the Confirmation Order. The Bankruptcy Court will retain
jurisdiction to hear and determine all Claims against the Debtors and to enforce
all causes of action that may exist on behalf of the Debtors. Nothing contained
in this Plan will prevent the Creditors Committee or Creditors Trust from taking
such action as may be necessary in the enforcement of any cause of action that
may exist on behalf of the Debtors and that may not have been enforced or
prosecuted by the Debtors.

re-examination of Claims that have been allowed for the purposes of voting, and
the determination of such objections as may be filed to Creditors' Claims. The
failure by the Creditors Committee to object to, or to examine, any Claims for
the purposes of voting will not be deemed a waiver of their right to object to,
or to re-examine, the Claim in whole or in part.

         9.3 Determination of Disputes. The Bankruptcy Court will retain
jurisdiction after the Confirmation Date to determine all questions and disputes
regarding title to the assets of the Debtors' estate, disputes concerning the

Confirmation Date, for the Debtors to recover assets pursuant to the provisions
of the Bankruptcy Code.

         (d) to adjudicate matters arising in these bankruptcy cases, including

enforce the title, rights, and powers of the Creditors Trust and Reorganized
Debtor and to impose such limitations, restrictions, terms and conditions on
such title, rights, and powers at this Bankruptcy (court may deem necessary;


                                      -28-
<PAGE>   33

inconsistency in this Plan or the order of confirmation as may be necessary to
carry out the purposes and intent of this Plan;

         (h) to allow applications for fees and expenses pursuant to Section
503(b) of the Bankruptcy Code; and

         liquids ("HYDROCARBONS") produced from or attributable to the Oil and
         Gas Properties before November 1, 1999. If; on the Closing Date,

<PAGE>   5


         Gas Properties unit stock tanks or are located within unit gathering
         lines or production facilities upstream of the sale or custody transfer
         meters of the Seller or in connection with Hydrocarbon production from
         the Oil and Gas Properties, Buyer shall purchase from Seller the
         merchantable stock tank oil and/or gas above the pipeline connections
         in the stock tanks at the field posting price for such oil and gas or
         such price being paid for production under the Seller's relevant
         existing sales contract of each such property existing as of the
         Effective Date, and any pipeline inventory at the mutually agreed upon
         market price of such inventory. Buyer will pay Seller for the stock
         tank oil and any pipeline inventory related thereto as an adjustment to
         the Base Purchase Price at Closing. The stock tank oil and pipeline
         inventories will be gauged and measured as of 7:00 a.m. local time
         where the Oil and Gas Properties and Assets may be located on the
         Effective Date. Seller and Buyer will accept the lease or unit
         operator's tank gauge readings, meters, meter tickets or other
         inventory records of the stock tank oil and pipeline inventory.

               1.1.2 PRODUCTION AFTER NOVEMBER 1, 1999. Buyer will own all
Hydrocarbons produced from the Oil and Gas Properties and Assets from and after
November 1, 1999, assuming that the December 6, 1999 Closing Date occurs.
Subject to any continuing sale obligations under Related Contracts, Buyer may
sell Hydrocarbons produced from the Oil and Gas Properties on and after the
Closing Date as it deems appropriate.

     2. PRICE FOR ASSETS. The initial, unadjusted Purchase Price to be paid by
Buyer to Seller for the Assets is Ninety-Six Million Two Hundred Fifty Thousand
and No/100 Dollars ($96,250,000.00) (excluding Lake Mongoulois and Mustang
Island, as defined in Schedule 2) (the "BASE PURCHASE PRICE"). In accordance
with the Bid Procedures, Buyer has previously tendered to an escrow account for
the benefit of Seller with Bank One Texas, N.A. ("Escrow Agent") the amount of
Three Million, Four Hundred Thousand and No/100 Dollars ($3,400,000.00) (the
"INITIAL DEPOSIT"). Buyer has deposited with the Escrow Agent an additional
escrow sum for the benefit of Seller in an additional amount of Six Million Two
Hundred Twenty Five Thousand and No/100 Dollars ($6,225,000.00)(the "ADDITIONAL
DEPOSIT"), which deposits shall together total 10% of the Base Purchase Price.

        2.1 ALLOCATION OF PURCHASE PRICE. The Buyer(s) and Seller agree that, on
or before the Closing Date, they will attempt to mutually agree as to the
allocation of the Base Purchase Price among each of the assets under the
Internal Revenue Code, as amended, and its regulations, including the relative
portions of those values attributable to leasehold costs and depreciable
equipment (the "Allocated Value"). If there is a disagreement concerning any
such allocation(s), such dispute will be resolved by the Court.

     has, or will have at Closing, full power to enter into and perform its
     obligations hereunder, and has, or will have at Closing, taken all
     necessary action to authorize entering into this Agreement and to perform
     its obligations hereunder.

        (b) The Oil and Gas Properties and Assets shall be sold free and clear
     of all liens, claims, encumbrances, and interests pursuant to Section
     363(f) of the Bankruptcy Code in an order to be approved by the Court.

        (c) Other than requirements (if any) that consents to assignment, or
     waivers of preferential rights to purchase, be obtained from third parties,
     and except for approvals required to be obtained from governmental entities
     who are lessors under leases forming a part of the Oil and Gas Properties,
     or who administer such leases on behalf of such lessors, which are
     customarily obtained post-closing, or as otherwise set forth on Schedule
     3(c), neither the execution and delivery of this Agreement, nor the
     consummation of the transactions contemplated hereby, nor the compliance
     with the terms hereof, will result in any default under any agreement or
     instrument to which Seller is a party or by which the Assets are bound, or
     violate any order, writ, injunction, decree, statute, rule or regulation
     applicable to Seller or to the Assets.

        (d) This Agreement and the Conveyance provided for herein to be
     delivered at Closing will, when executed and delivered, constitute the
     legal, valid, and binding obligation of Seller, except as subject to notice
     provisions and order of the Court.

        (e) Take-or-Pay Arrangements. Except with respect to Reliant Energy,
     Inc., gas balancing agreements, wells subject to calls on production, and
     preferential rights as set forth in Exhibit B, none of the Oil and Gas
     Properties are subject to any take or pay arrangements, advance payment or
     similar provision, whereby any party has the right to take production
     without full payment therefore, or at a reduced or prearranged price or to
     a call on production.

        (f) New Well Operations. From November 1, 1999 until Closing, Seller
     shall not make any election with respect to any operation for the drilling

     plugging back, plugging and abandonment or other operation with respect to
     any well, unit or lease constituting part of the Oil and Gas Properties,
     without the prior written consent of Buyer (as the Winning Bidder), which
     consent will not be unreasonably withheld. Buyer shall respond promptly to
     any written requests for such consent.

        (g) Maintenance of Interest. Seller will use its reasonable commercial
     efforts from the date of this Agreement until Closing, to maintain and
     operate the Assets in a reasonable and prudent manner, in compliance with
     law and orders of any governmental authority, to maintain insurance now in
     force with respect to the Assets, to pay when due all costs and expenses
     coming due and payable in connection with the Assets, and to perform all of
     the covenants and conditions contained in the Related Contracts. Without
     the prior written consent of Buyer, which consent will not be unreasonably

     operation or accounting with respect to the Assets; (ii) enter into any new
     agreements or commitments with respect to the Assets; (iii) incur any

     of the Assets other than personal property that is replaced with equivalent
     property or consumed in the ordinary course of operation of the Assets and
     other than Hydrocarbons sold in the ordinary course of business; or (vii)
     enter into any new production purchase or sale agreement with a term
     greater than 30 days relating to the Assets. If selected as a Winning Bid,
     Buyer will respond promptly to any written requests for such consent.

        (h) Filings. Seller has timely filed or caused to be filed all federal,
     state, local and foreign tax and information returns, and all material
     reports, certificates and other instruments required by law.

        (i) Operating Agreements. Except as disclosed to Buyer, as to any and
     all operating agreements affecting any of the Oil and Gas Properties, each
     of which operating agreements constitutes a Related Contract: (i) there are
     no outstanding calls, advances or payments that have been advanced on
     behalf of or are due from Seller or that Seller has committed to make that
     have not been paid, (ii) there are no operations with respect to which
     Seller is a non-consenting party, and (iii) except for an emergency, and
     payment for any materials or services rendered prior to the date of this
     Agreement, Seller will not authorize any expenditure after the date of this
     Agreement without first obtaining the written consent to such expenditure
     from Buyer, once selected as a Winning Bid, which consent will not be
     unreasonably withheld, conditioned or delayed

     4. REPRESENTATIONS OF BUYER. Buyer represents to Seller that:

        (a) Buyer is a corporation duly organized and legally existing and under
     the laws of the State of Nevada, and as of the Closing, Buyer will be
     qualified to do business and in good standing in each of the states in

     corporation owning the Assets located in such state to qualify to do
     business.

                                       6

        (b) Buyer has full power to enter into and perform its obligations under
     this Agreement and has taken all proper action to authorize entering into
     this Agreement and performance of its obligations hereunder.

        (c) Neither the execution and delivery of this Agreement, nor the

     instrument to which Buyer is a party.

        (d) This Agreement and the Conveyance provided for herein to be
     delivered at Closing will, when executed and delivered, constitute the
     legal, valid, and binding obligation of Buyer, enforceable in accordance
     with its terms, except as limited by bankruptcy or other laws applicable
     generally to creditor's rights and as limited by general equitable
     principles.

        (e) There are no pending suits, actions, or other proceedings except the

     5. CERTAIN COVENANTS OF SELLER PENDING CLOSING. Between the Sale Hearing
(as defined in the Bid Procedures) and the Closing:

        (a) Seller will give Buyer and its attorneys and other representatives
     access at all reasonable times to the Assets and, at Seller's office, to
     Seller's records (including, without limitation, title files, division
     order files, well files, production records, accounting records, marketing
     files, equipment inventories, and production, severance and ad valorem tax
     records) pertaining to the ownership and/or operation of the Assets. Seller
     shall not be obligated to provide Buyer with access to any records or data
     which Seller considers to be proprietary or confidential to it, which would
     constitute a waiver of attorney-client privilege in any pending litigation,
     or which Seller cannot legally provide to Buyer without, in its opinion,
     breaching, or risking a breach of, confidentiality agreements with other
     parties.

                                       7

<PAGE>   9


     Buyer recognizes and agrees that all materials made available to it
     (whether pursuant to this Section or otherwise) in connection with the
     transaction contemplated hereby are made available to it as an
     accommodation, and without representation or warranty of any kind as to the
     accuracy and completeness of such materials. Buyer waives and releases all
     claims against Seller, its parent or subsidiary companies or other
     affiliates, and its and their directors, officers, employees and agents,
     for injury to, or death of, persons or for damage to property arising in
     any way from the conduct of the investigations and examinations
     contemplated by this Section or the conduct of its employees, agents, or
     contractors in connection with such investigations and examinations (or the
     exercise of such rights of access). BUYER SHALL RELEASE, INDEMNIFY, DEFEND,
     AND HOLD HARMLESS SELLER, AND ITS PARENT OR SUBSIDIARY COMPANIES AND OTHER
     AFFILIATES, AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, ATTORNEYS,
     CONTRACTORS, AND AGENTS (HEREINAFTER COLLECTIVELY REFERRED TO AS THE
     "SELLER GROUP"), FROM ANY AND ALL CLAIMS, ACTIONS, CAUSES OF ACTION,
     LIABILITIES, DAMAGES, LOSSES, COSTS, OR EXPENSES (INCLUDING, WITHOUT
     LIMITATION, COURT COSTS AND ATTORNEYS' FEES), OR LIENS OR ENCUMBRANCES FOR
     LABOR OR MATERIALS ARISING OUT OF OR IN ANY WAY CONNECTED WITH SUCH ACCESS,
     EXAMINATIONS, OR INSPECTIONS. THE FOREGOING RELEASE AND INDEMNIFICATION
     SHALL APPLY WHETHER OR NOT SUCH CLAIMS, ACTIONS, CAUSES OF ACTION,
     LIABILITIES, DAMAGES, LOSSES, COSTS, OR EXPENSES ARISE OUT OF (i)
     NEGLIGENCE (INCLUDING SOLE NEGLIGENCE, SINGLE NEGLIGENCE, CONCURRENT
     NEGLIGENCE, ACTIVE NEGLIGENCE, OR PASSIVE NEGLIGENCE, BUT EXPRESSLY NOT
     INCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT) OF SELLER OR ANY OTHER
     INDEMNIFIED PARTY, OR (ii) STRICT LIABILITY.

        (b) In addition to its obligations under Section 3(g) of this Agreement,
     Seller will continue the operation of the Assets in the ordinary course of
     its business. Where Seller is not the operator of an Oil and Gas Property,
     Seller will continue to act as a non-operator in the ordinary course of its
     business. From and after the date of this Agreement, Seller will not sell
     or dispose of any portion of the Assets listed in Exhibit A except for the
     few miscellaneous assets listed in Schedule 5(b) without the prior consent
     of Buyer.

        (c) Seller will use reasonable efforts, consistent with industry
     practices in transactions of this type, to identify (i) all preferential
     rights to purchase and all rights to require that consents to assignment be
     obtained which would be applicable to the transactions contemplated hereby,
     and (ii) the parties holding such rights. In attempting to identify the
     same, Seller shall in no event be obligated to go beyond its own records.
     Seller will request from the parties so identified (and in accordance with
     the documents creating such rights) waivers of the preferential rights to
     purchase and requirements that consents to assignment be obtained which
     were so identified. Seller shall have no obligation hereunder other than to
     so attempt to identify such preferential rights and requirements for
     consents to

                                       8

<PAGE>   10


     assignment and to so request such waivers, and shall in no event be under
     any obligation to obtain such waivers. Except to the extent that Buyer can
     establish that Seller failed to fulfill the obligations set forth above in
     this subsection, Buyer shall indemnify and hold Seller harmless from and
     against all claims, actions, liabilities, damages, losses, costs or
     expenses, including, without limitation, court costs and attorney's fees,
     whatsoever that arise out of the failure to obtain waivers of preferential
     rights to purchase or requirements for consents to assignment with respect
     to any transfer by Seller to Buyer of any part of the Assets and with
     respect to any subsequent transfers.

        (d) Notwithstanding any other provision in this Section, (i) Seller may
     take any action prohibited by this Section if reasonably necessary under
     emergency conditions provided that Buyer is notified as soon as practicable
     thereafter; (ii) except to the extent that a Title Defect (as hereinafter
     defined) may result therefrom, Seller shall have no liability to Buyer for
     any incorrect payment of delay rentals, royalties, shut-in royalties, or
     similar payments or for any failure to make such payments; and (iii)
     Seller's failure to comply with any of the requirements of this Section 5
     shall not be deemed to be a default by Seller hereunder or grant to Buyer
     the right not to close the transaction contemplated hereby, unless such
     failure has a material adverse effect upon the value of the Assets taken as
     a whole.

        (e) Seller shall give prompt written notice to Buyer of any notice of
     default (or written threat of default, whether disputed or denied by
     Seller) received or given by Seller subsequent to the Effective Date under
     any instrument or agreement affecting the Assets to which Seller is a party
     or by which it or any of the Assets is bound.

     6. DUE DILIGENCE/TITLE/ENVIRONMENTAL MATTERS

        (a) Due Diligence Investigation. Buyer shall, to the extent it deems
     appropriate, conduct, at its sole cost, risk, and expense, such title
     examination or investigation, and other examinations and investigations, as
     it may choose to conduct with respect to the Assets.

        (b) As used in this Agreement, the term "TITLE DEFECT" shall mean any
     matter, other than a "Permitted Encumbrance" (as hereinafter defined),
     which causes one or more of the following to be a correct statement:

                 (i) Seller's ownership of the Assets is such that, with respect
            to a well or unit listed on Exhibits A or B attached hereto, such
            ownership (a) is not sufficient to entitle it to receive its decimal
            share of the oil, gas and other hydrocarbons produced from, or
            allocated to, such well or unit which is at least that decimal share
            set forth on Exhibit B in connection with such well or unit in the
            column headed "NET REVENUE INTEREST" or (b) obligates it to bear its
            decimal share of the cost of operation of such well or unit (herein
            called the "OPERATING INTEREST") greater than the decimal share set
            forth on Exhibit B in connection with such well or unit in the

                                       9

<PAGE>   11


            column headed "Operating Interest" (without a proportionate increase
            in Net Revenue Interest above that set forth on such exhibits); or


                (ii) Seller's ownership of an Oil and Gas Property is subject
            to an outstanding mortgage (other than that set forth in Section
            6(c)(xii)), deed of trust, or other enforceable lien or
            encumbrance, or other adverse claim or imperfection in title that is
            not resolved or cured by the 363 Order (as defined in Section 17
            hereinafter); or

                (iii) Seller has materially misrepresented the amount of any
            gas imbalances as to assets listed in Exhibit B.

                (iv) Seller has inaccurately represented outstanding
            preferential rights.

            (c) As used herein, the term "PERMITTED ENCUMBRANCE" shall mean any
     and all of the following:

                (i) The terms, conditions, restrictions, exceptions,
            reservations, limitations, and other matters contained in the
            agreements, instruments, and other documents which create or reserve
            to Seller its interest in any Asset, provided that the same do not
            reduce the Net Revenue Interest of Seller in the Asset affected
            thereby to less than that set forth on Exhibit B hereto;

                (ii) Royalties, overriding royalties (including, without
            limitation, those specifically described on Exhibit A hereto),
            division orders, reversionary interests, production payments, net
            profits interests, and similar burdens affecting any Oil and Gas
            Property if the net cumulative effect of such burdens does not
            operate to reduce the Net Revenue Interest in the Asset affected
            thereby to less than the Net Revenue Interest set forth beside the
            same on Exhibit B hereto;

                (iii) Preferential rights to purchase and required third party
            consents to assignment and similar agreements with respect to which
            waivers or consents shall have been obtained from the appropriate
            parties, or the appropriate time period for asserting such rights
            shall have expired without an exercise of such rights;

                (iv) Liens for taxes and assessments which are not yet
            delinquent or which are being contested by Seller in good faith;

                (v) Rights existing under applicable laws (including without
            limitation statutory liens) or operating agreements or similar
            contracts to assert liens against the Assets, but not including
            liens and other rights which have actually been asserted, unless
            Seller disputes the validity of such liens or the amount claimed to
            be owed in

                                       10

            connection therewith, or such lien or other right is not enforceable
            against the interest of Seller;

                (vi) Conventional rights of reassignment requiring ninety (90)
            days or less notice to the holder of such rights;

                (vii) Easements, rights-of-way, servitudes, permits, surface

            Asset which does not materially and adversely affect the Asset
            affected thereby or its current use;

                (viii) Any obligations or duties affecting an Asset to any
            municipality or public authority with respect to any franchise,

                (ix) All rights to consent by, required notices to, filings
            with, or other action by governmental entities in connection with
            the sale or conveyance of oil and gas leases, permits, or interests
            therein, if the same are customarily obtained contemporaneously with
            or subsequent to such sale or conveyance;

                (x) Existing operating agreements, unit agreements, gas
            purchase contracts, and any and all other agreements which are

            or extraction business or in the business of processing of gas and
            gas condensate, or production for the extraction of proper products
            therefrom, to the extent that the same do not reduce the Net Revenue
            Interest of Seller in the Asset affected thereby below that set
            forth on Exhibit B hereto, or increase the Operating Interest of the
            Seller in the affected Asset above that set forth on Exhibit B
            (without a proportionate increase is the corresponding Net Revenue
            Interest);

                (xii) Any matter waived or deemed to be waived by Buyer.

            (d) Title Defects. Should, as a result of such examinations and
     investigations, or otherwise, matters come to Buyer's attention which Buyer
     believes would constitute Title

                                       11

<PAGE>   13


     Defects, Buyer shall notify Seller in writing of such Title Defects as soon
     as practicable, but in no event later than sixty (60) days after the
     Closing. To be effective, Buyer's notice of Title Defects (a "TITLE DEFECT
     NOTICE") must include (i) a brief description of the matter constituting
     the Title Defect so asserted, (ii) the title opinion, other reports of
     experts, or other documentation on which Buyer's assertion of a Title
     Defect is based, (iii) such supporting documents reasonably necessary for
     Seller to verify the existence of any such Title Defect, and (iv) Buyer's
     estimate of the diminution in the value of the affected Asset resulting
     from such alleged Title Defect. In the event that Buyer notifies Seller of
     Title Defects, Seller (i) shall have the right (but not the obligation) to
     attempt to cure such Title Defects to the reasonable satisfaction of Buyer,
     or (ii) shall have the right to elect not to cure the Title Defect and
     adjust the Base Purchase Price as set forth in Section 7 below, subject to
     the limits of Section 6(h) below. Should the title opinion or other
     materials reviewed by Buyer indicate that Seller has a higher "Net Revenue
     Interest" than that specified on Exhibit (an "NRI INCREASE"), then Buyer
     shall inform Seller of the same as soon as possible and Seller will receive
     an appropriate accounting adjustment as set forth in Section 7 below.

        (e) Environmental Review. Seller has provided or caused to be provided
     to Buyer that Phase I environmental summary October 16, 1999 and prepared
     by LFC Environmental, Inc. covering certain of Seller's Oil and Gas
     Properties; provided, that Seller makes no representation or warranty as to
     the accuracy or completeness of such Phase I environmental summary. In
     addition, Buyer shall have the right, at its sole cost, risk, and expense,
     to conduct its own Phase I environmental assessment of the Assets during
     the period beginning November 1, 1999 and ending sixty (60) days after the
     Closing. As used herein, a Phase I environmental assessment shall consist
     of the following: Buyer and its agents shall have the right to enter upon
     the Assets and all buildings and improvements thereon during normal
     business hours, and physically inspect the same, contact all relevant
     local, state, and federal environmental agencies, and conduct a review of
     all public filings with respect to the Assets. WITHOUT THE PRIOR WRITTEN
     CONSENT OF SELLER, BUYER MAY NOT CONDUCT, OR CAUSE TO BE CONDUCTED, ANY
     SOIL, AIR, OR WATER TESTS, ANALYSES, SAMPLES, OR BORINGS WITH RESPECT TO
     ANY OF THE ASSETS, except, however, after Closing Buyer shall have the
     right to conduct any soil, air, or water tests, analyses, samples, or
     borings with respect to any of the Assets and any results from such
     investigation may be used as documentation to support an Environmental
     Defect Notice as provided in Section 6(t) below.: Buyer shall provide
     Seller with a copy of any environmental assessment promptly upon Buyer's
     completion thereof; including any reports, data, and conclusions. Buyer
     shall keep any data or information acquired by such examinations and the
     results of all analyses of such data and information strictly confidential
     and shall not disclose same to any person or agency without the prior
     written approval of Seller. BUYER SHALL RELEASE, INDEMNIFY, DEFEND, AND
     HOLD HARMLESS THE SELLER GROUP FROM AND AGAINST ANY AND ALL LOSS, COST,
     DAMAGE, EXPENSE, OR LIABILITY WHATSOEVER, INCLUDING ATTORNEYS' FEES,
     ARISING OUT OF ANY INJURY TO OR DEATH OF PERSONS OR DAMAGE TO PROPERTY
     OCCURRING IN, ON, OR ABOUT THE ASSETS AS A RESULT OF SUCH

                                       12

<PAGE>   14


     ENVIRONMENTAL ASSESSMENT (EXCEPT ANY SUCH INJURIES OR DAMAGES CAUSED SOLELY
     BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY MEMBER OF THE SELLER
     GROUP).

        (f) Environmental Defects. If; as a result of Phase I or Phase II, as
     provided in Section 6(e) above, examinations and investigations, or
     otherwise, matters come to Buyer's attention which Buyer believes would
     constitute a violation of an Applicable Environmental Law (hereafter
     defined) (an "ENVIRONMENTAL DEFECT"), Buyer shall notify Seller in writing
     of such Environmental Defect as soon as practicable (the "ENVIRONMENTAL
     DEFECT NOTICE"), but in no event later than sixty (60) days after the
     Closing. To be effective, Buyer's Environmental Defect Notice must include
     (i) a brief description of the Environmental Defect constituting the
     violation of Applicable Environmental Law so asserted, (ii) the reports of
     experts or other documentation on which Buyer's Environmental Defect Notice
     is based, (iii) such supporting documents reasonably necessary for Seller
     to verify the existence of any violation of an Applicable Environmental
     Law, and (iv) Buyer's estimate of the diminution in the value of the
     affected Asset resulting from such alleged Environmental Defect, or if such
     exceeds the diminution in value, the amount to remediate such alleged
     Environmental Defect. In the event that Buyer notifies Seller of
     Environmental Defects, Seller (i) shall have the right (but not the
     obligation) to attempt to cure such Environmental Defects to the reasonable
     satisfaction of Buyer; or (ii) shall have the right to elect not to cure
     the Environmental Defect and adjust the Base Purchase Price as set forth in
     Section 7 below, subject to the limits of Section 6 (h) below. Any plugging
     and abandonment obligation with respect to any well, and any surface
     restoration liability with respect to any oil, gas and/or mineral lease
     shall not constitute or be deemed an Environmental Defect

        (g) Environmental Indemnity and Assumption. As of sixty (60) days after
     the Closing Date, Buyer shall assume full responsibility for, and (except
     to the extent that Buyer shall have received a reduction in the Base
     Purchase Price pursuant to this Agreement by virtue of an Environmental
     Defect) agrees to indemnify, hold harmless, and defend the Seller Group
     from, and against all loss, liability, claims, fines, expenses, costs
     (including attorney's fees and expenses), and causes of action caused by or
     arising out of any violation of any environmental law, rule, or regulation
     (including common law), relating to the protection of health or the
     environment of any kind or character ("APPLICABLE ENVIRONMENTAL LAW(S)")
     or the presence, disposal, release or threatened release of any Hazardous
     Substance (as the terms "HAZARDOUS SUBSTANCE" and "RELEASE" are defined in
     the Comprehensive Environmental Response, Compensation and Liability Act,
     42 U.S.C. Sec. 9601, et seq.) from, with respect to, or in connection with
     the Assets into the atmosphere, into or upon land (surface or subsurface),
     or into any water course or body of water, including groundwater, whether
     or not attributable to the Seller's activities or the activities of third
     parties (regardless of whether or not the Seller was or is aware of such
     activities) and regardless of whether the event or occurrence was prior to,
     during, or after the period of Seller's ownership of the Assets. This
     indemnification and assumption shall

                                       13

<PAGE>   15


     apply, but is not limited to, liability for response actions undertaken
     pursuant to the Comprehensive Environmental Response, Compensation and
     Liability Act or any other Applicable Environmental Law or regulation.

        (h) Defect Basket/Limits. Notwithstanding any other provision contained
     herein, with respect to any Asset, the amount claimed by Buyer in any Title
     Defect Notice related to a given Asset shall not exceed the Allocated Value
     (as defined in Section 7 below) of such Asset. The amount claimed by Buyer
     for the remediation of an Environmental Defect shall not be limited to the
     Allocated Value of the affected Asset, but is subject to the limits set
     forth in this section. If the aggregate Base Purchase Price reduction which
     would result from all Title Defects and Environmental Defects does not
     exceed One Million Dollars ($1,000,000.00) (the "DEFECT BASKET AMOUNT"),
     then the Base Purchase Price shall not be adjusted. If the total amount of
     the Base Purchase Price reduction agreed to by the Parties (or determined
     by the Court) exceeds the Defect Basket Amount, the Base Purchase Price
     shall be reduced in the amount by which the aggregate amount of Title
     Defects and Environmental Defects exceeds One Million Dollars
     ($1,000,000.00); provided, however, regardless of the total amount of Title
     and Environmental Defects asserted by Buyer and agreed to by Seller (or
     determined by the Court) in excess of the Defect Basket Amount, in no event
     shall the Base Purchase Price be reduced by an amount greater than Two
     Million Dollars ($2,000,000.00).

     7. CERTAIN BASE PURCHASE PRICE ADJUSTMENTS. If, as a part of the due
diligence review provided for in Section 6 above, (i) Title Defects or
Environmental Defects are presented to Seller and Seller is unable (or
unwilling) to cure such Title or Environmental Defects, (ii) Buyer has elected
to treat an Oil and Gas Property affected by a casualty loss as if it was an Oil
and Gas Property affected by a Title Defect, or (iii) there be a NRI Increase,
then:

        (a) Subject to Section 6 (h) above, Buyer and Seller shall, with
     respect to each Oil and Gas Property affected by such matters, attempt to
     agree upon an appropriate value to account for such matters; and

        (b) with respect to each Oil and Gas Property as to which Buyer and
     Seller are unable to agree upon appropriate adjustment with respect to all
     such matters affecting such Oil and Gas Property, then:

                 (i) If the Title Defect is a mortgage, lien, encumbrance or
            other charge which is undisputed and liquidated in amount, then
            (subject to the provisions of paragraph (iv) below) the value shall
            be the amount necessary to be paid to remove the Title Defect from
            the affected Asset; provided, however, that an order conveying such
            Oil and Gas Properties to Buyer free and clear of liens or interests
            under Section 363(f) of the Bankruptcy Code shall suffice to cure or
            resolve such defect ("363(f) ORDER");

                                       14

<PAGE>   16


                 (ii) If there shall be a Title Defect or NRI Increase which (a)
            represents a discrepancy between (1) the Net Revenue Interest to
            which Seller is entitled to receive from any Asset and (2) the Net
            Revenue Interest stated on Exhibit B, and (b) there is a Operating
            Interest change proportionate to the change in the Net Revenue
            Interest resulting from the Title Defect or NRI Increase, then the
            amount of the adjustment shall be the product of the Allocated Value
            as set forth on Exhibit B, multiplied by a fraction, the numerator
            shall be the change in the Net Revenue Interest and the denominator
            of which shall be the Net Revenue Interest set forth on Exhibit B;
            or

                 (iii) If the Title Defect represents an obligation,
            encumbrance, burden, discrepancy, or charge upon or other defect in
            title to the affected Asset of a type not described in paragraphs
            (i) or (ii) above, the adjustment amount shall be determined by
            taking into account the Allocated Value of the Asset so affected,
            the portion of the Asset affected by the Title Defect, the legal
            effect of the Title Defect, the potential economic effect of the
            Title Defect over the life of the affected Asset, and such other
            factors as are necessary to make a proper evaluation of the value of
            the Title Defect;

                 (iv) With respect to Environmental Defects, the value shall be
            determined by taking into account the Allocated Value of the Asset
            so affected, the portion of the Asset affected by the Environmental
            Defect, the legal effect of the Environmental Defect (including
            governmental agency-imposed fines or sanctions, if any), the
            potential economic effect of the Environmental Defect over the life
            of the affected Asset, and such other factors as are necessary to
            make a proper evaluation of the value of the Environmental Defect
            including the cost of remediation;

                 (v) The Parties shall negotiate in good faith to reach
            agreement with respect to the existence of and diminution in value
            caused by Title and Environmental Defects with respect to the Assets
            hereunder. If the Parties are unable to agree upon an appropriate
            adjustment within 45 days following notice of such Title and/or
            Environmental Defect in light of the factors set forth above, then,
            subject to Section 6 (h) and the final paragraph of this Section
            7, either Party may elect to submit a dispute regarding the value of
            any Environmental or Title Defect(s) to the Court for final
            determination.

        Any Base Purchase Price adjustment hereunder shall be made as a
        post-Closing accounting adjustment in accordance with Section 13 below.

     8. CERTAIN COVENANTS OF BUYER AFTER CLOSING. From and after the date of
this Agreement, Buyer will give Seller and its attorneys and other

     11. TERMINATION OF AGREEMENT.

         (a) If any condition on the obligations of Buyer as set forth in
     Section 9 above is not met as of the Closing Date, or in the event the

         (b) If any condition to the obligations of Seller as set forth in

     Seller shall retain the Initial and Additional Deposit, including interest
     calculated in each Deposit as liquidated damages. Thereafter, the parties
     shall have no further obligations to one another hereunder (other than the

                                       17

<PAGE>   19


     condition of Seller Default shall exist. Buyer shall cooperate with Seller

Dallas, Texas, on December 6, 1999, at 10:00 a.m. Central Time, or up to
fourteen (14) days later if requested by either Buyer or the Committee on behalf
of the Seller, or at such other date and time as the Buyer and Seller may
mutually agree upon, being herein called the "CLOSING DATE"). At the Closing:

         (a) Seller shall upon issuance of the 363(f) and 365 Orders (as defined
     in Section 17 hereinafter) authorizing the transaction:

             (i) execute, acknowledge and deliver to Buyer a conveyance of the
         Assets, (herein called the "CONVEYANCE"), in the form attached hereto
         as Exhibit C (and with Exhibit A and Exhibit B-l hereto being attached
         thereto), effective as to runs of oil and deliveries of gas as of 7
         o'clock a.m., Central Standard Time on November 1, 1999 (herein called
         the "EFFECTIVE DATE"); and

             (ii) execute and deliver to Buyer letters in lieu of transfer
         orders (or similar documentation), in form acceptable to both parties;
         and

             (iii) deliver to Buyer a release of the Mortgage and 363(f) Order
         insofar as it covers the Assets; and

             (iv) deliver to Buyer an affidavit or other certification that
         Seller is not a "foreign person" within the meaning of Section 1445 (or
         similar provisions) of the Internal Revenue Code of 1986 as amended;
         and

             (v) turn over possession of the Assets; and

             (vi) provide Buyer with Seller's Officer Certificate having the
         form and language of Exhibit D-l which is attached hereto and made a
         part hereof for all purposes. Such certificate shall certify that
         Seller has complied with and performed (or Buyer has waived) all
         provisions and conditions pertaining to Seller, to be performed prior
         to the Closing.

         (b) Buyer shall:

                                       18

<PAGE>   20


             (i) deliver to the Seller, (a) by wire transfer in immediately
         available funds to an account designated by Seller in a bank located in
         the United States, an amount equal to the Base Purchase Price (or, if
         applicable, the Subgroup Price) less the Initial Subgroup Deposit and
         the Additional Subgroup Deposit and interest calculated upon each
         deposit. In addition to and consistent with Section 363(k) of the
         Bankruptcy Code, Buyer shall be entitled to credit bid against the Base
         Purchase Bid the amount of its loan to Seller of $25,000,000 plus any
         accrued and unpaid interest; and

             (ii) deliver to Seller appropriate evidence reflecting change of
         operator as required by applicable authorities, and such evidence as
         Seller may require that Buyer is qualified with such authorities to
         succeed Seller as operator; and

             (iii) provide Seller with Buyer's Officer Certificate having the
         form and language of Exhibit D-2 which is attached hereto and made a
         part hereof for all purposes. Such Certificate shall certify that Buyer
         has complied with and performed (or Seller has waived) all provisions
         and conditions pertaining to Buyer, to be performed prior to the
         Closing.

             At the Closing, at Buyer's election, Seller and Buyer shall enter
         into a transition services agreement with respect to the Assets on
         terms and conditions mutually acceptable to the Parties. The transition
         services agreement shall provide, among other things, for (i) the
         operation of the Assets by Seller, and (ii) the payment by Buyer to
         Seller of fees and expenses customarily charged by firms providing such
         services. The Transition Services Agreement shall terminate one hundred
         twenty (120) days following the Closing Date, unless extended by the
         Parties or terminated by Buyer upon thirty (30) days prior written
         notice.

             Within ten (10) days after Closing, Seller will deliver to Buyer
         the original records and other materials described in Section 1(f)
         above. Sellers shall have the right to retain a copy of such records
         for use only in connection with the Case, at Seller's expense. With
         respect to each Oil and Gas Property with respect to which Seller is
         disbursing proceeds of production attributable to other patties
         entitled thereto, (i) Seller shall continue to collect proceeds of
         production during the month in which Closing occurs and shall be
         responsible for making disbursements, in accordance with its normal
         procedures (and at normal times), of such proceeds of production so
         collected to the parties entitled to same, with any proceeds of
         production thereafter collected by Seller to be promptly forwarded to
         Buyer (who shall thereafter account for same to the parties entitled
         thereto), (ii) Seller shall, as promptly as possible after Closing,
         deliver to Buyer (a) a copy of its "proceeds distribution list" for
         each such Asset (which proceeds distribution list shall include the
         name, address, social security number and applicable share of proceeds
         of production for each party to whom Seller is disbursing proceeds of
         production with

                                       19

<PAGE>   21


         respect to such Asset), (b) a list of all parties for whom it is
         holding in suspense proceeds of production, (c) a list of all parties
         for whom it is holding any advance payments made by other working
         interest owners for operations to be conducted on the Assets, and (d) a
         check (which shall be delivered within 30 days after the end of the
         month in which Closing occurs) in an amount equal to all suspended
         funds and advance payments. Following delivery of the materials
         referred to in clause (ii), Buyer shall become responsible for all
         disbursements of proceeds of production (including suspense and other
         disbursements attributable to periods prior to the Effective Date) and
         such disbursement activities shall be included in the matters which
         Buyer assumes, and indemnifies Seller with respect to, under Section 14
         below. It is understood and agreed that Seller does not represent or
         warrant to Buyer the accuracy of the "proceeds distribution lists" so
         delivered.

     13. CERTAIN POST-CLOSING ACCOUNTING ADJUSTMENTS.

         (a) Appropriate post-Closing adjustments shall be made between Buyer
     and Seller so that (i) all expenses which are incurred in the operation of
     the Assets before the Effective Date will be borne by Seller and all
     proceeds (net of applicable production, severance, and similar taxes) from
     sale of oil, gas and/or other minerals produced therefrom before the
     Effective Date will be received by Seller, and (ii) all expenses which are
     incurred in the ownership and/or operation of the Assets after the
     Effective Date will be borne by Buyer and all proceeds (net of applicable
     production, severance, and similar taxes) from the sale of oil, gas and/or
     other minerals produced therefrom after the Effective Date will be received
     by Buyer. It is agreed that, in making such adjustments: (i) oil which was
     produced from the Oil and Gas Properties and which was, on the Effective
     Date, stored in tanks located on the Oil and Gas Properties (or located
     elsewhere but used by Seller to store oil produced from the Oil and Gas
     Properties prior to delivery to oil purchasers) and above pipeline
     connections shall be deemed to have been produced before the Effective
     Date, (ii) ad valorem and similar such taxes assessed with respect to a
     period which the Effective Date splits, regardless of the basis on which
     such taxes are computed, shall be prorated based on the number of days in
     such period which fall on each side of the Effective Date (with the day on
     which the Effective Date falls being counted in the period after the
     Effective Date), and shall, where the current year's taxes are not yet
     known, be based on the previous year's taxes, and (iii) no consideration
     shall be given to the local, state or federal income tax liabilities of any
     party. In addition, there shall be a post-Closing accounting adjustment, to
     the extent necessary, to adjust the Base Purchase Price as provided in
     Sections 6 and 7 above, in the event that Title or Environmental Defects
     exceed the Defect Basket Amount or there is an NRI Increase in favor of the
     Seller in any Asset.

         (b) As soon as practicable after Closing, but in any event within sixty
     (60) days thereafter, Seller shall prepare and submit to Buyer, in
     accordance with this Agreement a proposed statement (herein called the
     "FINAL STATEMENT"), which shall show the final calculation of the Purchase
     Price, which may include good faith estimates or accruals for oil

                                       20

<PAGE>   22


     and gas receivables and all other post-Closing adjustments (herein called
     the "FINAL SETTLEMENT PRICE"). As soon as possible after receipt of the
     Final Statement, but in any event within fifteen (15) days after receipt
     thereof, Buyer shall deliver to Seller a written report containing the
     changes, if any, which Buyer proposes being made to the Final Statement. In
     the event no response is made by Buyer within such fifteen (15) day period,
     it shall be conclusively presumed that Buyer concurs with the Final
     Statement, and such Final Statement shall be the basis for the Final

     business days thereafter by the party owing the same in immediately
     available funds.

     discovery of Hazardous Substances or other deleterious substances in, on,
     or under the Assets, regardless of when the events occurred that give rise
     to such condition).

         (b) Buyer shall, on the date of Closing, RELEASE, INDEMNIFY, and HOLD
     the Seller Group HARMLESS from and against any and all claims, actions,

     giving rise to the claim. In that regard, if any suit, action, claim,
     liability or obligation (a "PROCEEDING") shall be brought or asserted by
     any third party which, if adversely determined, would entitle the Seller to
     indemnity under this Agreement, the Seller shall promptly notify the Buyer
     of the same in writing, specifying in detail the basis of such claim and
     the facts pertaining thereto. The Buyer, if it so elects, shall assume and
     control the defense of such Proceeding, including the employment of
     counsel reasonably satisfactory to the Seller and the payment of expenses.
     If the Buyer elects to assume and control the defense of a Proceeding, it
     will provide notice thereof within thirty (30) days after the Seller has
     given notice of the matter and the Seller shall have the right to employ
     counsel separate from counsel employed by the Buyer in any such action and
     to participate in the defense thereof, but the fees and expenses of such
     separate counsel employed by the Seller shall be at the sole cost and
     expense of the Seller.

understanding that it is subject to (i) approval by the Bankruptcy Court, (ii)
any other offers which may be timely submitted to the Bankruptcy Court, in
accordance with the bid procedures and (iii) the applicable provisions of the
Bankruptcy Code and the Federal Rules of Bankruptcy Procedure.

(including a copy this Agreement). The 363 Motion shall seek approval of the
sale of the Oil and Gas Properties, and other Assets to Buyer free and clear of
any interest of an entity other than the Debtor's bankruptcy estate. Such 363

order shall be in a form reasonably

                                       23

<PAGE>   25


satisfactory to Buyer and Buyer's counsel and the proposed findings of fact and
conclusion of law, if any, and form of order shall include the provisions and
relief described below as the 363 Order. Seller shall obtain a hearing on the
363 Motion as soon as practicable.

     17.3 As soon as practicable following the selection of Buyer and this
Agreement as a Winning Bid in accordance with the Bid Procedures, Seller shall

in this Section 17.3 in the 363 Motion) ("365 Motion") with supporting papers.
The 365 Motion shall seek (i) approval of the assumption by Seller and
assignment to Buyer of all Related Contracts, (except those Related Contracts
that Buyer designates herein that Buyer does not wish to have assumed and
assigned) ("Assigned Contracts"), (ii) a specific finding regarding Seller's
cure of any defaults under such Assigned Contracts at the time of Closing; and
(iii) the rejection by Seller of Related Contracts designated by Buyer and
agreed to by Seller (and the Creditors' Committee) as Related Contracts to be
rejected (or such executory contracts as may be rejected by Seller). Such 365
Motion, proposed findings of fact and conclusions of law, if any, and proposed
order shall be in form and substance reasonably satisfactory to the Buyer and
Buyer's counsel and such proposed findings of fact and conclusions of law, if
any, and form of order shall include the provisions and relief described below
as the 365 Order. Seller shall obtain a hearing on the 365 Motion as soon as
practicable. If additional Related Contracts are identified by Buyer or Seller
after the execution and delivery of this Agreement that are not described in
this Agreement and in the 365 Motion, then Seller will seek to obtain Bankruptcy
Court approval, at Buyer's election, of (a) the rejection by Seller (if agreed
to by Seller and the Creditors' Committee) of the applicable additional Related
Contracts designated by Buyer to be rejected, or, (b) the assumption by Seller
and assignment to Buyer of the applicable additional Related Contracts
designated by Buyer and agreed to by Seller (and the Creditors' Committee) to be
assumed and assigned to Buyer.

     17.4 Subject to the provisions of subsections 17.2 and 17.3 above, whether
the 363 Motion and 365 Motion are filed with the Bankruptcy Court and served as
one (1) motion or multiple motions is entirely within the discretion of the
Seller and the Creditors' Committee; provided, however, the 363 Motion and 365
Motion shall be served on all known creditors.

     17.5 "363 ORDER@ means an order, not susceptible to alteration or amendment
under Fed.R.Bankr.P.9023, of the Bankruptcy Court that (i) approves the 363
Motion, (ii) is in form and substance reasonably satisfactory to Buyer and
Buyer's counsel, (ill) approves the sale of the Oil and Gas Properties and other
Assets, to Buyer pursuant to the terms of this Agreement, the provisions of the
Bankruptcy Code and any other provisions ordered by the Bankruptcy Court. The
363 Order shall provide that the transfer of the Oil and Gas Properties from
Seller to Buyer shall be (i) free and clear of any interest in the Oil and Gas
Properties of an entity other than the estate, (ii) a legal, valid and effective
transfer of the Oil and Gas Properties, (iii) a transfer in exchange for
reasonably equivalent value and fair consideration under the Bankruptcy Code and
the laws of the United States, any State, territory, possession or the District
of Columbia and (iv) finds that the sale of the Assets to Buyer will maximize
the value of the Seller's estate and is in contemplation of the implementation
of a plan of reorganization and necessary to the confirmation and consummation
of any plan of reorganization. Accordingly, the sale of the Assets shall be
deemed a sale "under a plan confirmed"

                                       24

<PAGE>   26


within the meaning of Bankruptcy Code Section 1146(c) and shall be exempt from
any and all stamp taxes, recording taxes and similar taxes; provided, however,
that such exemption is contingent upon the Seller confirming a plan of
reorganization under Section 1129 of the Bankruptcy Code. Further, the 363 Order
shall provide that the transaction contemplated under this Agreement (i) was and
is undertaken by the Seller and Buyer in good faith, as the term is used in
section 363(m) of the Bankruptcy Code, and, (ii) does not and will not subject
Buyer to any pre-conveyance liability by reason of such Oil and Gas Properties
or Assets transfer under the Bankruptcy Code or the laws of the United States,
any State, territory, possession or the District of Columbia based, in whole or
in part, directly or indirectly, on any theory of law, including, without
limitation, any theory of successor or transferee liability unless provided in
or contemplated under the terms of this Agreement.

     17.6 "365 ORDER@ means an order of the Bankruptcy Court that (i) approves
the 365 Motion, (ii) is in form and substance reasonably satisfactory to Buyer
and Buyer's counsel, (iii) approves the assumption by Seller and assignment to
Buyer of the Oil and Gas Properties and the Related Contracts, (iv) contains a
specific finding regarding Seller's cure of any defaults under such Related
Contracts at the time of Closing, (v) approves the rejection by Seller of the
applicable Related Contracts. The 365 Order shall further provide that, if
additional Related Contracts arc identified by Buyer or Seller after the
execution and delivery of this Agreement that are not described in this
Agreement and in the 365 Motion, then if Seller agrees, then Buyer shall seek to
obtain Bankruptcy Court approval, at Buyer's election, of (a) the rejection by
Seller of the applicable additional Related Contracts designated by Buyer to be
rejected, or (b) the assumption by Seller and assignment to Buyer of the
applicable additional Related Contracts designated by Buyer to be assumed and
assigned.

     17.7 Whether the 363 Order and the 365 Order are submitted to the Court in
the form of one (1) order or two (2) orders is entirely within the discretion of
Seller and Creditors' Committee.

     17.8 On or before November 8, 1999, Seller shall deliver to the Buyer a
schedule ("Schedule of Assumed Contract Deficiencies"), which shall indicate as
to each Related Contract the amounts, if any, in Seller's understanding,
necessary or required under Section 365(b) of the Bankruptcy Code to remedy and
cure all monetary arrears under each of the Related Contracts ("Assumed Contract
Deficiencies") in order to effectuate the assumption and assignment of such
Related Contracts. Buyer shall have the right to obtain appropriate assurances
from the Seller or the Court that the Seller has paid, or made arrangements
reasonably acceptable to the Buyer to satisfy, all such Assumed Contract
Deficiencies. If the Seller disputes the amount necessary to cure a Related
Contract, the Seller will either establish an escrow fund and deposit the full
cure amount estimated by Seller or asserted by the non-debtor party to such
Related Contract into an escrow fund or if the Committee and Seller determine
the cure amount asserted by a party to a Related Contract is excessive, they may
decide to reject such contract under Section 365 of the Bankruptcy Code. Any
disputes in this regard will be resolved by the Bankruptcy Court. Buyer shall
pot be liable for any cure amounts under any of the Related Contracts. The
validity of the assumption, assignment and sale to Buyer of any Related Contract
shall not be affected by any dispute between the Seller and

                                       25

<PAGE>   27


another party to such Related Contract regarding the payment of the "cure"
amount under such Related Contract. Notwithstanding anything contained herein to
the contrary, the Seller shall be deemed to have assumed and assigned each
Related Contract as of the date of and only upon the Closing, and absent such
Closing, such Related Contract shall neither be deemed assumed nor assigned and
shall in all respects be subject to further administration under the Bankruptcy
Code.

     18. CASUALTY LOSS. In the event of damage by fire or other casualty to the
Assets prior to the Closing, then this Agreement shall remain in full force and
effect, and (unless Buyer and Seller shall otherwise agree) in such event

         (a) as to each such Asset so damaged which is an Oil and Gas Property,
     then, (i) if there is no policy of insurance in force with respect to such
     Asset, such Asset shall be treated as if it had a Title Defect associated
     with it and the procedure provided for in Section 6 shall be applicable
     thereto, or (ii) if Seller should be entitled to make any claim under any
     insurance policy with respect to such damage, Seller shall and/or pay over
     to Buyer, if assignable, or, if allowed under the applicable policy, such
     claims, and

         (b) as to each such Asset which is other than an Oil and Gas
     Properties, Seller shall assign to Buyer, if assignable, any and all
     insurance claims relating to such loss, and Buyer shall take title to the
     Asset affected by such loss without reduction of the Purchase Price.

         (c) At Buyer's election, Seller shall use its reasonable commercial
     efforts to assign its rights to and under its casualty and other insurance
     policies to Buyer to be effective as of the Closing Date (or thereafter at
     Buyer's election). In the event that a refund is due and payable by the
     insurance carrier as a result of the assignment by Seller to Buyer, Seller
     shall be entitled to receive such refund amount.

Agreement shall (unless otherwise specifically provided herein) be in writing

         (c) No waiver of any provision of this Agreement shall be deemed or
     shall constitute a waiver of any provision of this Agreement (whether or
     not similar), nor shall such waiver constitute a continuing waiver unless

             governmental order, decree, regulation, or rule (provided that

         directly or indirectly a party, or (b) that is controlled directly or
         indirectly by such party, or (c) is directly or indirectly controlled

                   (b) employees, officers, and directors of an Affiliated
             Company;

                   (c) any professional consultant or agent retained by Buyer
             for the purpose of evaluating the Confidential Information.

         permit the use of the Confidential Information disclosed under Section

     ORDERED that any plan of reorganization filed or sponsored by Arnos or NEG
shall provide for a Creditor Trust into which shall be transferred and assigned
all claims, causes of action and rights of NEG under Sections 541-553 of the
Bankruptcy Code, as well as any and all rights of the estate of the Debtor to
investigate and prosecute, claims against the officers and directors of NEG and
its former accountants, Ernst & Young, and, in the interim no lawsuits may be
filed by the Committee until a plan is filed and there is further Court Order;
and it is further

     ORDERED that if the Closing takes place, all proceeds, benefits, income and
revenues from the Assets attributable to the period from and after November 1,
1999 will be allocated to Arnos but that NEG on behalf of Arnos shall pay all
costs and expenses incurred in NEG's business pertaining to the ownership,
operation and maintenance of the Assets, including appropriate allocation of
general and administrative expenses, attributable to the period from and after
November 1, 1999 through the earlier of the effective date of a plan of

income, revenues, costs and expenses and a proposed allocation as between Arnos
and NEG of general and administrative expenses each month; and it is further

     ORDERED that if the Closing takes place, the proceeds, benefits, income,
revenues, costs and expenses relating to the Assets from and after November 1,
1999 shall be accounted for at the time of and in connection with the Closing of
the sale of the Assets pursuant to the PSA or the implementation of a plan of
reorganization, as the case may be, such that Arnos will ultimately receive the
benefit of such proceeds, benefits, income and revenues and Arnos will
ultimately bear the burden of such allocation of expenses attributable to the
Assets after November 1, 1999 and the Committee may contest any allocation at
any time and reserves the right to argue that such allocation should include a
profit for the Debtors;

     ORDERED that Arnos will pay separately the reasonable fees and expenses of
Neligan & Averch L.L.P., or its successor in name, as counsel for NEG from
December 13, 1999 forward incurred in connection with any plan of reorganization
that Arnos may sponsor, but such payment shall be predicated on Court order
approving the fees and expenses of Neligan & Averch, L.L.P. or its successor;
and it is further

     ORDERED that the Court shall determine the sufficiency of any additional
consideration to be funded by Arnos for the unsecured creditors in connection
with any plan of reorganization sponsored by Arnos or the Debtor, with Arnos and
the Creditors' Committee agreeing to waive any rights of appeal therefrom; and
it is further

     ORDERED that any Arnos sponsored plan and disclosure statement shall be
filed at the earliest practical date, and that in the event the Creditors'
Committee is not satisfied with progress on the filing of an Arnos sponsored
plan, it may seek a hearing to request that the Escrowed Proceeds be released
and the transactions contemplated by the PSA be consummated, and it is further

     ORDERED that, from and after December 13, 1999, the implementation of the
sale contemplated by the PSA will be deemed to be held in abeyance in
accordance with the PSA, unless earlier concluded by order of this Court or by
written declaration from Arnos that it is no longer seeking to confirm a plan
and will proceed to close under the PSA, or a plan of reorganization proposed by

Interests and the sale of the Assets to Arnos pursuant to this Order and the PSA
