                               PROSPECTUS SUMMARY
 
   
     The following summary is qualified in its entirety by the more detailed
information and financial statements, including notes thereto, appearing
elsewhere in this Prospectus. Certain terms, including several technical terms
commonly used in the oil and gas industry, are defined in the "Glossary." As
used in this Prospectus, the terms "Company" and "CNG" refer, unless the context
requires otherwise, to Continental Natural Gas, Inc., its subsidiaries
(including limited liability companies), joint venture entities managed by the
Company or its subsidiaries and their interests therein. Unless otherwise noted,
all references in this Prospectus to the number of shares of Common Stock
outstanding and to be offered in the Offering assume no exercise of the
over-allotment option granted to the Underwriters in connection with the
Offering and the conversion of all outstanding shares of Convertible Preferred
Stock of the Company ("Convertible Preferred Stock") into Common Stock prior to
the effectiveness of the Registration Statement of which this Prospectus is a
part. All information in this Prospectus has been adjusted to reflect an
approximate 136-for-1 stock split in July 1997. No information is given in this
Prospectus regarding the Company's recent acquisitions of the Spearman gas
processing plant and of the Laverne gas processing plant except in "-- Recent
Developments" and in "Business -- Recent Developments."
    
 
                                  THE COMPANY
 
     The Company is an independent mid-stream energy company engaged in the
purchasing, gathering, treating, processing and marketing of natural gas and
natural gas liquids ("NGLs"). The Company owns and operates approximately 1,100
miles of natural gas gathering pipelines located in the Texas and Oklahoma
panhandle region (the "Panhandle Area") with a total throughput capacity of 383
MMcf/d and two interconnected natural gas processing plants with a total NGL
production capacity of 490 Mgal/d. CNG provides essential services to natural
gas producers in the Panhandle Area by (i) connecting the producers' wells to
the Company's gathering systems, (ii) treating the producers' natural gas to
ensure that it meets pipeline specifications, (iii) transporting the natural gas
from the wellhead to CNG's processing plants where NGLs are extracted from the
natural gas stream and (iv) providing access for the natural gas and NGLs to
various markets in the Midwestern, Mid-Continent, Rocky Mountain and southern
Texas regions (the "CNG Market Area") of the United States. The April 1996 and
January 1997, editions of "Hart's Report on Gas Customer Satisfaction" published
by Hart Publications, Inc. reported that CNG was rated the most preferred
natural gas purchaser in surveys of natural gas sellers. The Company markets the
natural gas it gathers or processes ("on-system gas"), as well as natural gas it
neither gathers nor processes ("off-system gas"), to utilities, end-users, other
marketers and pipeline affiliates.
 
   
     From 1985 through 1990, CNG's activities were primarily limited to
marketing off-system gas. Concurrent with the evolving deregulation of the
natural gas industry, the Company began to acquire natural gas gathering systems
and processing plants to complement its marketing business. Since 1990, the
Company has completed approximately $64 million of acquisitions and system
expansion projects. During March 1997, CNG's average gathering system throughput
was 108 MMcf/d and average processing plant throughput was 135 MMcf/d. The
Company's NGL production for March 1997, averaged 281 Mgal/d. Over the three
years ended December 31, 1996, the Company's daily natural gas throughput has
increased 92%. Primarily as a result of this growth, the Company's EBITDA (as
defined in the Glossary) has increased to $9.5 million in 1996 from $1.7 million
in 1994. For the three months ended March 31, 1997, the Company's EBITDA was
$3.7 million.
    
 
   
     The Company's principal assets are located in the Panhandle Area, which is
a major natural gas producing area with significant long-lived natural gas
reserves. CNG's Beaver Plant and Beaver Gathering System were acquired in 1990
from El Paso Natural Gas Company and currently consist of approximately 300
miles of natural gas gathering pipelines, a 65 MMcf/d cryogenic processing plant
and a 40 MMcf/d propane refrigeration plant yielding NGL production of 215
Mgal/d. The Beaver Plant is interconnected with the Company's Mocane Plant,
which was acquired from affiliates of Conoco, Inc. and Chevron USA, Inc. in
1995. The Mocane Plant consists of two refrigerated lean oil absorption plants
with a combined demonstrated capacity of 200 MMcf/d of natural gas and 280
Mgal/d of NGLs, approximately 140,000 barrels of underground NGL storage and a
6,700 barrel per day NGL fractionator. During the first half of 1996, the
Company acquired approximately 800 miles of gas gathering assets located
throughout the Texas panhandle in three separate transactions. These gathering
assets (the "Texas Gathering Assets") were acquired for approximately $20.2
million from subsidiaries of Enron Corporation.

                               BUSINESS STRATEGY
 
     The Company's business strategy is to achieve sustainable growth in cash
flow and earnings by (i) acquiring and constructing natural gas gathering
systems and processing plants with excess capacity which complement CNG's
marketing operations, (ii) improving the profitability of the Company's existing
systems and plants by increasing their utilization and efficiency and (iii)
expanding its energy marketing services and sales volumes by offering natural
gas producers and purchasers flexible contract terms, value-added services and
other favorable arrangements.
 
   
     Expansion of Facilities. The Company seeks to acquire or make investments
in projects that complement its existing systems or allow it to expand into new
strategic areas and provide enhanced marketing opportunities. These investments
typically include natural gas gathering, processing, treating or fractionation
assets.
    
 
   
     Improving the Profitability of Existing Facilities. The Company seeks to
maximize the profitability of its operations by (i) increasing natural gas
throughput and processing levels, (ii) directing natural gas throughput to a
particular Company-owned gas processing plant that maximizes product yields
and/or margins, (iii) investing in assets that enhance product value and (iv)
controlling operating and overhead expenses.
    
 
   
     Expanding Energy Marketing Services and Sales Volumes. CNG is a marketer of
natural gas and NGLs. The Company plans to expand its energy marketing
activities by continuing to offer creative, flexible contract terms that satisfy
the objectives of producers at the wellhead and purchasers in the marketing of
natural gas. The Company also seeks to increase its off-system marketing. In
addition, the Company intends to expand into the sale of electric power to
wholesale customers and industrial and commercial end-users. See
"Business -- Business Strategy."
    
 
   
                              RECENT DEVELOPMENTS
    
 
   
     In July 1997 the Company completed the acquisition of the Spearman gas
processing plant (the "Spearman Plant") located in Ochitree County, Texas, for a
purchase price of approximately $1.0 million. The Spearman Plant was shut-down
in 1994 and has remained idle since that time. The current maximum throughput of
the Spearman Plant is estimated to be approximately 50 MMcf/d utilizing a
refrigerated lean-oil absorption process, producing approximately 86 Mgal/d of
NGLs. The Company believes that it will be able to utilize the Spearman Plant
for processing natural gas the Company gathers through its nearby Spearman
gathering system which is part of the Texas Gathering Assets.
    
 
   
     In July 1997 the Company purchased from Conoco, Inc. ("Conoco") and its
affiliate a 36% interest in the Laverne gas processing plant (the "Laverne
Plant") located in Harper County, Oklahoma, for a purchase price of $2.9 million
(the "Laverne Plant Acquisition"). Prior to the Laverne Plant Acquisition, the
Company had acquired approximately 17% of the plant for $1.4 million and
presently owns approximately 53% of the Laverne Plant. Concurrent with the
Laverne Plant Acquisition, certain litigation between the Company and the Conoco
affiliate was settled. See "Business -- Legal Proceedings."
    
 
   
     The Laverne Plant consists of a 200 MMcf/d cryogenic gas processing
facility, complete with NGL fractionation capability and above-ground storage.
The Laverne Plant straddles GPM Gas Corporation's Laverne natural gas gathering
system. Natural gas production feeding the Laverne Plant originates from the
Mocane-Laverne field. The plant is located approximately eight miles east of the
Beaver Plant. Current natural gas throughput at the Laverne Plant is
approximately 70 MMcf/d, yielding approximately 180 Mgal/d of NGLs. Due to the
Laverne Plant's proximity to CNG's other assets and its substantial
underutilized capacity, the Company believes that the Laverne Plant will enhance
the Company's existing operations in the Panhandle Area.

                                  RISK FACTORS
 
     In addition to the other information contained in this Prospectus, the
following factors should be considered carefully in evaluating the Company and
its business before purchasing the Common Stock offered hereby.
 
COMMODITY PRICE FLUCTUATIONS
 
     The Company's products, including NGLs, natural gas and related
by-products, are commodities. Because the Company's contracts generally do not
fix a long-term price for the products it purchases or sells, market changes in
the price of such products have a direct and immediate effect (whether favorable
or adverse) upon the revenues and profitability of the Company. In particular,
because the Company is a purchaser of natural gas at the wellhead and a seller
of NGLs extracted from natural gas, a contraction in the margin between the cost
of natural gas and the sales price of NGLs could adversely affect the Company.
 
     Prices for the Company's products are subject to material change in
response to relatively minor changes in supply and demand, general economic
conditions and other market conditions over which the Company has no control.
Other conditions affecting the Company's business include the level of domestic
oil and gas production, the availability and prices of competing commodities and
of alternative energy sources, the availability of local, intrastate and
interstate transportation systems with adequate capacity, government regulation,
the seasons, the weather and the impact of energy conservation efforts.
 
AVAILABILITY OF NATURAL GAS SUPPLY
 
     The Company must connect new wells to its gathering systems, contract for
new natural gas supplies with third party pipelines or acquire additional
gathering systems in order to maintain or increase throughput levels to offset
depletion of wells currently under contract. Historically, while certain
individual facilities have experienced decreases in dedicated reserves, the
Company has connected new wells and contracted for new supplies with third-party
pipelines which more than offset production depletion of existing wells. The
ability to connect new wells to existing facilities is dependent upon levels of
oil and gas development activity near existing facilities. Significant
competition for connections to newly drilled wells exists in every geographic
area served by the Company. Significant competition also exists for the
acquisition of existing gathering systems. There can be no assurance that the
Company will renew its existing supply contracts or that it will be able to
acquire new supplies of natural gas at a rate necessary to offset depletion of
wells currently under contract.
 
CONTINUED CONTROL BY MAJORITY SHAREHOLDERS
 
   
     After giving effect to the Offering, Adams Affiliates, Inc. ("Adams
Affiliates") and Cottonwood Partnership (collectively, the "Majority
Shareholders"), will directly control approximately 57.3% of the outstanding
Common Stock (54.4% if the Underwriters' over-allotment option is exercised in
full). Gary C. Adams, the Chairman of the Board, President and Chief Executive
Officer of the Company, is Chief Executive Officer of Cottonwood Partnership
which, in turn, owns a majority interest in Adams Affiliates. See "Certain
Transactions." After the Offering, the Majority Shareholders will be able to
elect all of the Company's directors, control the management and policies of the
Company and determine the outcome of any matter submitted to a vote of the
Company's shareholders. This presents the potential for a conflict of interest
between the Company and its controlling officers, shareholders and directors.
Provisions of the Company's Certificate of Incorporation also strengthen the
control of the Majority Shareholders over the Company and may act to reduce the
likelihood of a successful attempt to take over the Company or any acquisition
of a substantial amount of Common Stock without the Majority Shareholders'
consent. See "Principal and Selling Shareholders" and "Description of Capital
Stock."
    
 
DEPENDENCE ON THIRD-PARTY PIPELINES
 
     In 1996, approximately 60% of the Company's natural gas volume was
delivered to its processing plants through the interstate pipeline systems of
Northern Natural Gas Company ("NNG") and Transwestern Pipeline Company ("TW"),
and substantially all sales of natural gas by the Company were effected through
 
                                        7
<PAGE>   10
 
deliveries on interstate pipelines. In addition, the Company has partially
relied on third-party gathering systems for access to and transportation of
contracted natural gas supplies. As a result, a curtailment of the Company's
supply of natural gas by pipelines or by third-party gathering systems, an
impairment of the Company's ability to transport natural gas on interstate
pipelines or a material increase in the rates charged to the Company for the
transportation of natural gas by reason of a change in federal regulations or
for any other reason, could have a material adverse effect upon the Company. In
such event, other transportation arrangements would have to be obtained or
alternative pipelines would need to be constructed by the Company. There can be
no assurance that economically alternative transportation would be available to
the Company or that alternative pipelines could be constructed economically.
 
     Interstate pipelines are authorized under the FERC regulations to impose
penalties in the event the Company's deliveries and receipts from the pipeline
are not balanced on a daily or monthly basis. The Company attempts to balance
purchases and sales of natural gas on a daily and monthly basis so that the
Company's total purchases and sales on any given day (or in any given month) are
equal, thereby not incurring any significant pipeline imbalance penalties.
Nonetheless, in the event the Company is unable to balance its purchases and
sales within prescribed tolerances, the Company may incur severe pipeline
balancing penalties or may be compelled to purchase natural gas at unattractive
prices in order to alleviate these imbalances. In either instance, the Company
could incur substantial losses. See "Business -- Sales and
Marketing -- Transportation."
 
NET OPERATING LOSS CARRYFORWARDS
 
     The Company has been able to utilize net operating loss carryforwards
("NOLs") to offset approximately $37 million of income in prior years and
thereby reduce or eliminate its tax liability. At December 31, 1996, the Company
had an available NOL of approximately $17.5 million, which it intends to utilize
to offset its taxable income for the current and future years. Due to the lack
of legal precedent with respect to the tax rules governing the Company's NOLs,
both the availability of the Company's NOLs and its prior utilization of NOLs
may be challenged. Management believes that the Company has been, and will
continue to be, legally entitled to use its NOLs. Should the Internal Revenue
Service audit and disallow prior or future use of the Company's NOLs and such
disallowance be upheld upon appeal, the Company would incur additional tax
liability, penalties and interest. Any such additional tax liability could have
a material adverse effect on the financial condition of the Company. The ability
of the Company to utilize its NOLs in the future will also depend upon the
generation of sufficient taxable income prior to the expiration of its NOLs.
Thus, there is no assurance that the Company will be able to utilize its NOLs
prior to expiration. See Note 8 of the Notes to the Consolidated Financial
Statements of the Company included herein.
 
     Pursuant to Section 382 of the Internal Revenue Code of 1986, as amended,
in the event that a substantial change in the ownership of the Company were to
occur in the future (whether through the sale of stock by the Majority
Shareholders, new issuances of stock by the Company, conversions, a redemption,
recapitalization, reorganization, any combination of the foregoing or any other
method) so that ownership of more than 50% of the value of the Company's capital
stock changed during any three-year period, the Company's ability to utilize its
NOLs could be substantially limited. For each taxable year ending after such a
change in ownership, the Company would not be able to fully use its NOLs; it
would only be able to use an amount equal to the "sec. 382 limitation." The sec.
382 limitation is an amount equal to a designated percentage of the equity value
of the Company at the time of the change of ownership. The percentage used is
the federal long-term tax-exempt rate.
 
     At present, neither the Company nor the Majority Shareholders intend to
sell stock, issue additional stock, make any acquisitions in exchange for stock
or take any other action which would constitute such a change in ownership and
cause the sec. 382 limitation to apply.
 
OPERATIONAL RISKS
 
     The Company is subject to all of the risks generally associated with the
gathering, processing, marketing and storage of natural gas and NGLs, including
damage or loss to its own personnel and property, as well as
 
                                        8
<PAGE>   11
 
the personnel and property of third-parties. Such loss or damage could result,
among other things, from acts of God, negligent acts of personnel, or systems
failures, resulting in fires and explosions, leakage of natural gas or spills of
NGLs. Any of these occurrences could result in the loss of natural gas and/or
NGLs, environmental pollution, personal injury claims or other damage to the
property of the Company and others. Losses resulting from the occurrence of such
events (notwithstanding insurance coverage for all or part of such losses) could
have a material adverse effect on the financial condition and results of
operation of the Company.
 
     The Company's inability to negotiate natural gas purchase or sale
agreements or NGL sale agreements on favorable terms, or the failure of
contracting third-parties to perform agreements with the Company could have a
material adverse effect on the Company.
 
DEPENDENCE ON KEY PERSONNEL
 
     The success of the Company will depend in large part on the personal
efforts of its Chairman of the Board, President and Chief Executive Officer,
Gary C. Adams, its Vice President of Marketing, Scott C. Longmore, its Vice
President of Operations, Terry K. Spencer, and its Vice President and
Controller, Garry D. Smith. The loss of the services of any of these persons
could have a material adverse effect on the Company.
 
RISKS PERTAINING TO ACQUISITIONS
 
     Part of the Company's business strategy is to expand through acquisitions.
The Company's future growth is partially dependent upon its ability to complete
suitable acquisitions and effectively integrate acquired assets into the
Company's operations. Suitable acquisitions, on terms acceptable to the Company,
may not be available in the future or may require the Company to assume certain
liabilities, including, without limitation, environmental liabilities, known or
unknown.
 
POTENTIAL VARIABILITY IN QUARTERLY OPERATING RESULTS
 
   
     Demand for the Company's primary NGL product, propane, and the Company's
principal commodity, natural gas, will generally increase during the winter
because both products are used as heating fuels. The amount of such increased
demand will depend to some extent upon the severity of the winter. Accordingly,
Company revenues are likely to increase during winter months although the amount
of increase and its effect on profitability cannot be predicted because of
variations in weather and because the Company is also a purchaser of natural gas
and typically experiences an increase in product costs during the winter.
Because of the seasonality of the Company's business and fluctuations in the
prices of its products, the Company's operating results for any past quarterly
period may not necessarily be indicative of results for future periods and there
can be no assurance that the Company will be able to achieve or maintain
profitability on a quarterly or annual basis in the future. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Seasonality."
    
 
DEPENDENCE ON ONE CUSTOMER
 
     Sales of NGLs to a single customer, a subsidiary of Mapco, Inc., accounted
for 12% and 23% of the total revenue of the Company for fiscal years 1996 and
1995, respectively; however, the Company does not believe that the loss of such
customer would have a material adverse effect on the Company because of the
availability of other customers for the Company's products.
 
NO PRIOR PUBLIC MARKET
 
   
     There has been no prior public market for the Company's Common Stock. Even
though the Common Stock has been approved for listing on the Nasdaq National
Market, there can be no assurance that an active trading market for the Common
Stock will develop or be sustained after the Offering or that purchasers of the
Common Stock will be able to resell their Common Stock at prices equal to or
greater than the initial public offering price. The initial public offering
price for the Common Stock will be determined by negotiation between the Company
and the representatives of the Underwriters based on several factors and may
bear no relationship to the market price of the Common Stock subsequent to the
Offering. Numerous factors,
    
 
                                        9
<PAGE>   12
 
   
including the general economy, announcements by the Company, its suppliers or
competitors and fluctuations in the Company's quarterly and annual operating
results, changes in earnings estimates by analysts, governmental regulatory
action and general trends in the industry could significantly affect the future
market price of the Common Stock. In addition, the stock market has historically
experienced volatility which has affected the market price of securities of many
companies and which has sometimes been unrelated to the operating performance of
such companies.
    
 
GOVERNMENT REGULATION AND ENVIRONMENTAL MATTERS
 
     The Company is subject to various local, state and federal laws and
regulations including environmental laws and regulations. The Company believes
that it is in substantial compliance with such laws and regulations; however,
there is no assurance that such laws and regulations will not be changed in the
future in a manner which will increase the burden and cost of compliance. In
addition, significant liability could be imposed on the Company for damages,
cleanup costs and penalties in the event of certain discharges into the
environment. See "Business -- Government Regulation" and
"Business -- Environmental Matters."
 
   
     In March 1992, an environmental site assessment of the Laverne Plant
indicated the presence of hydrocarbon-contaminated groundwater underlying a
portion of the plant site. Under the direction of the Oklahoma Corporation
Commission and based on the results of a pilot remediation project, a plan has
been developed to remediate the site utilizing a biofiltration process to be
installed during the last half of 1997 at an estimated cost of $1 million. The
Company's share of this total cost is expected to be approximately $170,000. See
"Business -- Recent Developments."
    
 
     The Company is currently involved in pending proceedings at the FERC in
which certain parties allege that the primary function of the Company's
processing plants is interstate transportation and thus that they are subject to
FERC rate and certificate regulation. While the Company believes that its
business is not subject to regulation by the FERC, it cannot predict the outcome
of these proceedings, nor can it predict the effect a ruling would have on the
Company's business. See "Business -- Government Regulation."
 
LITIGATION
 
     The Company is involved in certain legal proceedings. Although the Company
believes that the final outcome of any legal proceedings will not have a
material adverse effect on the Company, the inherent uncertainty of litigation
makes it impossible to give assurance regarding the effect of such litigation on
the Company. See "Business -- Legal Proceedings."
 
ANTI-TAKEOVER PROVISIONS
 
     The Certificate of Incorporation and Bylaws of the Company and Oklahoma law
include certain provisions that may be deemed to have anti-takeover effects and
may delay, defer or prevent a takeover attempt that a shareholder of the Company
might consider to be in the best interests of the Company or its shareholders.
See "Description of Capital Stock."
 
DILUTION
 
     Purchasers of Common Stock in the Offering will experience immediate and
substantial dilution in the amount of $5.74 in the net tangible book value per
share of Common Stock from the initial public offering price. See "Dilution."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     The availability for sale of certain shares of Common Stock held by
existing shareholders of the Company after the Offering could adversely affect
the market price of the Common Stock. The Company currently has outstanding
4,200,000 shares of its Common Stock. In addition, the Company has 600,000
shares reserved for future issuance upon the exercise of options or other rights
granted under the 1997 Stock Plan and 204,000 shares subject to outstanding
options under the 1996 Stock Plan. Of the 6,000,000 shares of Common Stock to
 
                                       10
<PAGE>   13
 
   
be outstanding following the Offering, the 2,100,000 shares being offered hereby
will be freely tradeable without restrictions or additional registration under
the Securities Act of 1933, as amended (the "Securities Act"). The remaining
3,900,000 shares were issued and sold by the Company in private transactions in
reliance upon exemptions from registration under the Securities Act. All of
these shares, except as limited by lock-up agreements, will be eligible for
resale pursuant to Rule 144 under the Securities Act ("Rule 144"). In connection
with the Offering, all shareholders of the Company have agreed not to offer,
sell or otherwise dispose of a total of 3,900,000 shares held by them for a
period of 180 days after the effective date of the Offering, without the prior
written consent of the representatives of the Underwriters. Substantially all of
the shares subject to this lock-up agreement would otherwise be available for
resale upon the effective date of the Offering under Rule 144. Sales of a
substantial amount of the currently outstanding shares of Common Stock in the
public market may adversely affect the market price of the Common Stock and the
ability of the Company to raise additional capital should such sales occur at a
time when it would be beneficial for the Company to sell securities. See
"Description of Capital Stock," "Shares Eligible for Future Sale" and
"Underwriting."
    
 
COMPETITION
 
   
     The Company faces strong competition in every aspect of its business,
including the purchase and transportation of natural gas and the sale of natural
gas and NGLs. The Company's competitors include major integrated oil and gas
companies, affiliates of major interstate and intrastate pipeline companies,
natural gas gatherers and natural gas marketers of varying size, financial
resources and experience. Many of these competitors, particularly those
affiliated with major oil and gas and interstate and intrastate pipeline
companies, have capital resources and control supplies of natural gas
substantially greater than those of the Company. See "Business -- Competition."

                                  THE COMPANY
 
   
     The Company is an independent mid-stream energy company engaged in the
purchasing, gathering, treating, processing and marketing of natural gas and
NGLs. From 1985 through 1990, CNG's activities were primarily limited to
marketing off-system gas. Concurrent with the evolving deregulation of the
natural gas industry, the Company began to acquire natural gas gathering systems
and processing plants to complement its marketing business. As a result of these
acquisitions, the Company now derives the majority of its operating income from
gathering, processing and marketing activities associated with these assets. The
Company does not own any natural gas reserves.
    
 
     During 1996, CNG transferred substantially all of its operating assets to
three limited liability companies in order to limit the potential liability of
any single operating company to the assets and business of that company. The
Company owns 99% of each such limited liability company and the remaining 1% is
owned by Continental Holdings Company, a wholly-owned subsidiary of CNG.
 
     Currently, approximately 90% of the outstanding Common Stock of the Company
is owned by the Majority Shareholders, which are affiliated entities. Gary C.
Adams, the Chairman of the Board, President and Chief Executive Officer of the
Company, is Chief Executive Officer of Cottonwood Partnership which, in turn,
owns a majority interest in Adams Affiliates. See "Principal and Selling
Shareholders." Following the Offering, those entities will own approximately
57.3% of the outstanding Common Stock of the Company.
 
     The Company's principal offices are located at 1412 South Boston, Suite
500, Tulsa, Oklahoma 74119. Its telephone number is (918) 582-4700.

<PAGE>   15
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 1,800,000 shares of
Common Stock offered by the Company hereby, at an assumed initial public
offering price of $13.00 per share, after deduction of the underwriting discount
and offering expenses payable by the Company, are estimated to be approximately
$21.1 million ($24.8 million if the Underwriters' over-allotment option is
exercised in full). The Company will receive none of the proceeds from the sale
of Common Stock by the Selling Shareholder.
 
   
     Of such proceeds, the Company plans to use approximately $20 million to pay
a portion of the Company's existing indebtedness to ING Capital Corporation
under its term loan, approximately $587,000 to pay accumulated dividends on the
Convertible Preferred Stock and the balance for other general corporate
purposes. The interest rate under the Company's term loan varies at the
Company's election and may be either (i) up to  3/4% (depending upon the
Company's financial performance) above the greater of (x) the arithmetic average
of the prime rates announced by Chase Manhattan Bank, Citibank, N.A. and Morgan
Guaranty Trust Company of New York or (y) the federal funds rate as published by
the Federal Reserve Bank of New York plus  1/2%; or (ii) 1.375% to 2.50%
(depending upon the Company's financial performance) above the London Interbank
Offered Rate (LIBOR). The Company's term loan matures on July 31, 2001. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
    
 
     Pending such uses, the net proceeds of the Offering will be invested in
short-term, interest-bearing investment grade securities, including government
obligations and other money market instruments.
 
                                DIVIDEND POLICY
 
     Although the Company paid a dividend of $24,217 in 1995, the Company does
not intend to pay any cash dividends on its Common Stock and anticipates that,
for the foreseeable future, it will retain any earnings for use in the operation
and expansion of its business. Payment of cash dividends in the future will
depend upon the Company's earnings, financial condition, any contractual
restrictions (including restrictions contained in agreements relating to the
Company's credit facility), restrictions imposed by applicable law, capital
requirements and other factors deemed relevant by the Company's Board of
Directors. The Company's current credit facility prohibits the payment of
dividends on its Common Stock until December 30, 1997, and thereafter prohibits
the payment of dividends in excess of 10% of the Company's annual consolidated
net income.

                                    DILUTION
 
     The pro forma net tangible book value of the Company as of March 31, 1997
was approximately $22.4 million or $5.34 per share of Common Stock. Net tangible
book value per share represents the amount of total tangible assets of the
Company less total liabilities, divided by the number of shares of Common Stock
issued and outstanding, adjusted for the conversion of the Convertible Preferred
Stock into 586,847 shares of Common Stock and the payment of cumulative unpaid
dividends of $699,000 as of March 31, 1997. After giving effect to the sale of
the 1,800,000 shares of Common Stock offered by the Company hereby at an assumed
initial public offering price of $13.00 per share and the application of the
estimated net proceeds therefrom as described under "Use of Proceeds," the pro
forma net tangible book value of the Company as of March 31, 1997 would have
been $43.5 million, or $7.26 per share. This represents an immediate increase in
net tangible book value of $1.92 per share to existing shareholders and an
immediate dilution of $5.74 per share to new investors.
 
     The following table illustrates this per share dilution:

     The computations in the table above exclude 204,000 shares of Common Stock
issuable upon the exercise of stock options granted under the 1996 Stock Plan
and 600,000 shares of Common Stock issuable pursuant to awards to be granted
under the 1997 Stock Plan. To the extent such awards under the 1997 Stock Plan
are made and vest or are exercised, there may be further dilution to new
investors. See "Management -- Executive Compensation."

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
   
     Since its formation, the Company has grown primarily as a result of
acquisitions, facilities expansions and connections of additional natural gas
reserves to its natural gas gathering systems. Additionally, the Company has
increased its natural gas and NGL marketing operations. All historical financial
information has been restated to reflect the Company's approximate 136-for-1
stock split effected in July 1997. This discussion and analysis should be read
in conjunction with the Consolidated Financial Statements of the Company and the
notes thereto included elsewhere in this Prospectus.
    
 
RESULTS OF OPERATIONS
 
     The Company's results of operations are determined primarily by the volume
of natural gas purchased, processed and resold in its natural gas gathering
systems and processing plants. The Company's off-system gas marketing activities
also contribute to its profitability. Acquisitions of the Texas Gathering Assets
in the second quarter of 1996 and the Mocane Plant in the first quarter of 1995
have had a significant impact on the Company's results of operations.
 
     Fluctuations in the price levels of natural gas and NGLs also affect
results of operations since the Company generally receives a portion of the
natural gas and NGLs revenue from natural gas throughput. Most of the Company's
operating expenses do not vary materially with changes in natural gas throughput
volume on existing systems; thus, increases or decreases in volumes on existing
systems generally have a direct effect on the Company's profitability.
Conversely, operating expenses such as compression rental and compression
maintenance expenses vary with volume changes as compressor units are added or
removed accordingly.
 
  Three Months Ended March 31, 1997 Compared to Three Months Ended March 31,
1996
 
     Revenues. Total operating revenue increased 125% to $88.5 million for the
three months ended March 31, 1997, compared to $39.3 million for the same period
in 1996. Total natural gas sales increased 141% to $78.8 million for the three
months ended March 31, 1997 from $32.7 million for the same period in 1996 as a
result of a $22.1 million price-related increase due to average sales prices of
$3.25 per Mcf in 1997 compared to $2.34 per Mcf in 1996 and a $24.0 million
volume-related increase due to sales of 66.3 MMcf/d in 1997 compared to 38.2
MMcf/d in 1996. This increase in volume resulted primarily from increases in
off-system gas marketing sales.
 
     NGL sales increased 43% to $8.9 million for the three months ended March
31, 1997, compared to $6.2 million for the same period in 1996 primarily as a
result of a $2.1 million price-related increase due to average NGL sales prices
of $0.37 per gallon in 1997 compared to $0.28 per gallon in 1996.
 
     The Company earned gathering fees of $0.8 million for the three months
ended March 31, 1997, as a result of the acquisition of the Texas Gathering
Assets. These assets are also utilized in the Company's processing activities by
purchasing natural gas from producers served by the Company's systems and
transporting it to the Beaver Plant for processing.
 
     Costs and Expenses. Total operating costs and expenses increased 128% to
$85.7 million for the three months ended March 31, 1997, compared to $37.7
million for the same period in 1996. Total natural gas costs increased 136% to
$81.4 million in 1997 from $34.5 million in 1996 as a result of increases in
price and volume. The $24.4 million price-related increase (resulting from a
change in average purchase prices of $3.07 per Mcf in 1997 from $2.15 per Mcf in
1996) was mitigated by approximately $0.5 million of avoided gathering fees
caused by the integration of the Texas Gathering Assets into the Company's
processing business. A $22.6 million volume-related increase resulted from
purchases of 294.8 MMcf/d in 1997 compared to 178.2 MMcf/d in 1996. This
increase in volume resulted primarily from increases in off-system gas marketing
purchases.
 
     Operating expenses increased 13% to $1.6 million for the three months ended
March 31, 1997 from $1.4 million for the same period in 1996. This was primarily
due to operating activities from the acquisition of the Texas Gathering Assets.
 
                                       18
<PAGE>   21
 
     General and administrative expenses increased 41% to $1.8 million for the
three months ended March 31, 1997 from $1.3 million in the same period in 1996.
This increase was due primarily to the addition of marketing personnel and
administrative support activities related to the Texas Gathering Assets.
 
   
     Depreciation, depletion and amortization increased 90% to $0.9 million for
the three months ended March 31, 1997 from $0.5 million for the same period in
1996 primarily due to the acquisition of the Texas Gathering Assets and
expansions at the Beaver Plant.
    
 
     Other Income (Expense). Interest income increased to $0.3 million for the
three months ended March 31, 1997 from $50,000 for the same period in 1996 due
to increased cash investments associated with contract advances received in the
fourth quarter of 1996. During these same time periods, interest expense
increased 350% to $1.5 million from $0.3 million primarily due to additional
debt incurred to finance the acquisition of the Texas Gathering Assets.
 
     Income Taxes. Income tax expense increased to $0.7 million for the three
months ended March 31, 1997 from $30,000 for the same period in 1996. For the
three months ended March 31, 1997, the Company's effective income tax rate
approximates the sum of the federal and state statutory rates, while in 1996 the
Company's effective tax rate was significantly impacted by its net operating
loss carryforwards.
 
  Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
     Revenues. Total operating revenue increased 104% to $246.7 million for the
year ended December 31, 1996, compared to $121.2 million for the same period in
1995. Total natural gas sales increased 118% to $208.8 million in 1996 from
$95.6 million in 1995 as a result of a $79.1 million price-related increase due
to average sales prices of $2.56 per Mcf in 1996, compared to $1.59 per Mcf in
1995 and a $34.1 million volume-related increase due to sales of 224.1 MMcf/d in
1996, compared to 165.1 MMcf/d in 1995. This increase in volume resulted
primarily from increases in off-system gas marketing sales.
 
     NGL sales increased 40% to $34.8 million for the year ended December 31,
1996, compared to $24.8 million in 1995, primarily as a result of a $10.0
million price-related increase due to average NGL sales prices of $0.36 per
gallon in 1996, compared to $0.26 per gallon in 1995.
 
     The Company earned gathering fees of $2.0 million for the year ended
December 31, 1996, as a result of the acquisition of the Texas Gathering Assets
in the second quarter of 1996.
 
   
     Other revenues including sales from oil and gas properties increased to
$1.1 million in 1996 from $0.8 million in 1995. All the Company's oil and gas
properties were sold to an affiliated entity in the third quarter of 1996 for
$0.3 million, which approximated book value. Oil and gas producing activities
contributed revenues of $0.6 million, $0.5 million and $0.2 million in 1996,
1995 and 1994, respectively.
    
 
     Costs and Expenses. Total operating costs and expenses increased 105% to
$240.0 million for the year ended December 31, 1996, compared to $117.2 million
for the same period in 1995. Total natural gas costs increased 110% to $225.5
million in 1996 from $107.6 million in 1995 as a result of increases in price
and volume. The $85.2 million price-related increase (resulting from a change in
average purchase prices of $2.46 per Mcf in 1996 from $1.53 per Mcf in 1995) was
mitigated by approximately $0.5 million of avoided gathering fees caused by the
integration of the Texas Gathering Assets into the Company's processing
business. A $32.7 million volume-related increase resulted from purchases of
251.1 MMcf/d in 1996, compared to 192.6 MMcf/d in 1995. This increase in volume
resulted primarily from increases in off-system marketing purchases.
 
     Operating expenses increased 37% to $6.0 million in 1996 from $4.4 million
in 1995. This was due mainly to the increased operating activities from
acquisition of the Texas Gathering Assets, expansions at the Beaver Plant and
inclusion of Mocane Plant operating expenses for the full year.
 
     General and administrative expenses increased 46% to $5.6 million in 1996
from $3.8 million in 1995. This increase was due primarily to the addition of
marketing personnel, administrative support activities related to the Texas
Gathering Assets and ad valorem tax increases in connection with the acquisition
of the Texas Gathering Assets and Beaver Plant expansion projects.

     Depreciation, depletion and amortization increased 109% to $2.9 million in
1996 from $1.4 million in 1995 primarily due to the acquisition of the Texas
Gathering Assets, expansions at Beaver Plant and inclusion of the Mocane Plant
for the full year.
 
     Other Income (Expense). Interest expense increased 196% to $2.7 million in
1996 from $0.9 million in 1995 due primarily to additional debt incurred to
finance the acquisition of the Texas Gathering Assets.
 
     Income Taxes. The Company's effective income tax rate in 1996 and 1995 was
significantly impacted by its net operating loss carryforwards. For financial
statement purposes, recognition of the net operating loss carryforwards resulted
in a tax benefit of $3.6 million in 1996 and $2.2 million in 1995. The Company
anticipates that its effective tax rate in 1997 will approximate the sum of the
federal and state statutory rates. See Note 8 to the Company's financial
statements included elsewhere herein.
 
  Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
 
     Revenues. Total operating revenue increased to $121.2 million for the year
ended December 31, 1995, from $120.3 million for the same period in 1994. Total
natural gas sales decreased 5% to $95.6 million in 1995 from $100.5 million in
1994 as a result of a $20.8 million price-related decrease due to average sales
prices of $1.59 per Mcf in 1995 compared to $1.93 per Mcf in 1994 and a $15.9
million volume-related increase due to sales of 165.1 MMcf/d in 1995, compared
to 142.4 MMcf/d in 1994. This increase in volume resulted primarily from
increases in on-system gas marketing sales.
 
     NGL sales increased 27% to $24.8 million for the year ended December 31,
1995, compared to $19.6 million in 1994, primarily as a result of a $4.1 million
price-related increase due to average NGL sales prices of $0.26 per gallon in
1995, compared to $0.22 per gallon in 1994 and a $1.1 million volume-related
increase due to sales of 265 Mgal/d in 1995, compared to 249 Mgal/d in 1994.
This volume-related increase included NGL sales volume from the Mocane Plant
acquisition of 104.0 Mgal/d, which was partially offset by decreased sales
volume of 83.4 Mgal/d due to the divestiture of a gathering and processing
system in Carlsbad, New Mexico (the "Carlsbad System") in 1994.
 
     Costs and Expenses. Total operating costs and expenses decreased to $117.2
million for the year ended December 31, 1995 from $120.1 million for the same
period in 1994. Total natural gas costs decreased to $107.6 million in 1995 from
$111.0 million in 1994 as a result of a $20.3 million price-related decrease due
to average purchase prices of $1.53 per Mcf in 1995 compared to $1.82 per Mcf in
1994 offset by a $16.9 million volume-related increase due to purchases of 192.6
MMcf/d in 1995, compared to 167.2 MMcf/d in 1994. This increase in volume
resulted primarily from increases in on-system gas marketing purchases.
 
     Operating expenses increased 11% to $4.4 million in 1995 from $3.9 million
in 1994, due primarily to increased operating activities from the acquisition of
the Mocane Plant.
 
     General and administrative expenses increased 7% to $3.8 million in 1995
from $3.6 million in 1994.
 
     Depreciation, depletion and amortization decreased 9% to $1.4 million in
1995 from $1.5 million in 1994, due primarily to the sale of the Carlsbad System
in 1994 offset partially by the acquisition of the Mocane Plant in 1995.
 
     Other Income (Expense). Interest expense decreased 27% to $0.9 million in
1995 from $1.3 million in 1994. A gain of approximately $3.9 million (net of
$1.3 million attributable to minority ownership interests) on the sale of
certain gathering and processing assets was recognized by the Company during the
fourth quarter of 1994. Additionally, in 1994, the Company recognized other
income of $2.0 million from key-man life insurance policy proceeds due to the
death of an officer.
 
     Income Taxes. The Company's effective income tax rate in 1995 and 1994 was
significantly impacted by its net operating loss carryforwards. For financial
statement recognition purposes, the net operating loss carryforwards resulted in
a tax benefit of $2.2 million in 1995 while tax expense was $0.1 million in
1994.

LIQUIDITY AND CAPITAL RESOURCES
 
     General. The Company's primary sources of liquidity and capital resources
historically have been net cash provided by operating activities and bank
borrowings. In addition, in 1994, the Company received $12.8 million from the
sale of the Carlsbad System. The Company's principal uses of cash have been to
fund operations and acquisitions.
 
     The following summary table reflects comparative cash flows for the Company
for the years ended December 31, 1994, 1995 and 1996 and the three months ended
March 31, 1996 and 1997:

</TABLE>
 
     For the three months ended March 31, 1997, net cash used in operating
activities increased by approximately $7.8 million from the same period in 1996.
This was mainly attributable to changes in working capital including the
repayment of contract advances totaling $14.5 million. Excluding net changes in
working capital components, the Company's operating activities generated $2.5
million for this period in 1997 and $1.9 million in 1996. Net cash provided by
operating activities for the year ended 1996, increased by approximately $14.7
million from the same period in 1995. The increase resulted primarily from
changes in working capital, including contract advances of approximately $22.8
million received by the Company related to commitments to sell natural gas and
NGLs. It is anticipated that all such contract advances will be repaid in 1997,
which will result in a decrease in cash flows from operating activities.
Excluding net changes in working capital components, the Company's operating
activities generated $6.6 million during 1996 as compared to $4.7 million in
1995, an increase of $1.9 million. Net cash provided by operating activities for
1995 increased by $7.0 million from 1994. This increase was due to a $2.0
million increase in net earnings adjusted for depreciation and amortization and
other noncash items and a $5.0 million increase from working capital components.
 
     Cash used in investing activities for the three months ended March 31, 1997
was primarily for expansion projects on the Texas Gathering Assets. Cash used in
investing activities for the same period in 1996 was mainly for the acquisition
of a portion of the Texas Gathering Assets on March 31, 1996. For the year ended
1996, cash used in investing activities was principally related to the
acquisition of the Texas Gathering Assets and various expansion projects on the
Texas Gathering Assets and the Beaver Gathering System. In 1995, cash used in
investing activities was related primarily to the acquisition of the Mocane
Plant and related expenditures for the expansion of the Mocane fractionation
facility and dual interconnecting pipelines from the Mocane Plant to the Beaver
Plant. Cash provided by investing activities in 1994 was related to the receipt
of $12.8 million from the sale of certain assets, which was offset by
approximately $3.1 million of various upgrade and expansion projects.
 
     Cash provided by financing activities for the three months ended March 31,
1997 resulted from borrowing under the Company's revolving facility used for
working capital requirements and funding various capital projects. Cash provided
by financing activities for the same period in 1996 resulted mainly from
long-term borrowing for the acquisition of a portion of the Texas Gathering
Assets. For the year ended 1996, cash provided by financing activities resulted
principally from long-term borrowing for the acquisition of the Texas Gathering
Assets. In 1995, cash provided by financing activities resulted primarily from
increased borrowing levels for various capital expenditures. In 1994, cash used
in financing activities resulted primarily from the repayment of long-term debt.
In 1996, the Company issued preferred stock and canceled certain indebtedness to
acquire the minority interest ownership of a partnership holding one of the
Company's processing plants.
 
                                       21
<PAGE>   24
 
Also in 1996, the Company redeemed 51 shares of Convertible Preferred Stock in
exchange for the cancellation of indebtedness due from an affiliated entity.
 
     At December 31, 1996, the Company had NOLs totaling approximately $17.5
million for regular tax purposes and $18.0 million for alternative minimum tax
purposes. If not utilized, these NOLs will expire from 1999 to 2003. Due to the
lack of existing legal precedent with respect to the tax rules governing the
Company's NOLs, both the availability of the Company's NOLs and its prior
utilization of NOLs (totaling approximately $37 million) may be challenged.
Disallowance of the use of the NOLs would result in taxes associated with prior
utilization of the NOLs being currently payable.
 
     The Company believes that the net proceeds from the Offering, together with
its current credit facilities and cash flows generated by its operations, will
be sufficient to meet its anticipated cash needs for working capital and capital
expenditures for at least the next twelve months. Thereafter, if cash generated
from operations is insufficient to satisfy the Company's liquidity requirements,
the Company may seek to obtain additional credit facilities, sell additional
equity or debt securities or adjust the level of its operating and capital
expenditures. The sale of additional equity securities could result in
additional dilution to the Company's shareholders.
 
     Financing Facilities. The Company entered into a Credit Agreement with ING
Capital Corporation as of December 30, 1996. The Credit Agreement contains a
revolving facility and a term loan facility. The revolving facility has a
maximum borrowing base of $25.0 million which had outstanding borrowings of $6.5
million as of March 31, 1997. Under the term loan facility approximately $33.6
million was outstanding as of March 31, 1997, while an additional $4.8 million
was available for certain future acquisitions, including the acquisition of
interests in the Laverne Plant. Interest rates under both the revolving facility
and term facility are variable, at the Company's election, at: (i) up to  3/4%
(depending upon the Company's financial performance) above the greater of (x)
the arithmetic average of the prime rates announced by Chase Manhattan Bank,
Citibank, N.A. and Morgan Guaranty Trust Company of New York or (y) the federal
funds rate as published by the Federal Reserve Bank of New York plus  1/2%; or
(ii) 1.375% to 2.50% (depending upon the Company's financial performance) above
the London Interbank Offered Rate (LIBOR). Current interest payments on the
revolving facility and repayments under the term facility began on January 31,
1997. The revolving facility contains a sub-limit permitting the Company to
issue Letters of Credit amounting, in the aggregate, to $18.0 million. As of
March 31, 1997, the aggregate amount outstanding under these Letters of Credit
was $6.0 million.
 
   
     The Company has also entered into a Letter of Credit and Reimbursement
Agreement with Christiania Bank, New York Branch. Under the Reimbursement
Agreement, Christiania Bank initially issued letters of credit in the aggregate
amount of approximately $21.0 million to secure the Company's obligation under
various contract advances. As of March 31, 1997, the aggregate amount
outstanding under these Letters of Credit was $11.1 million. The Company pays a
fee of 1 1/2% per annum for the amount of each Letter of Credit which is issued.
    
 
SEASONALITY
 
     The Company's results of operations fluctuate from quarter to quarter, due
to variations in the prices and sales volumes of NGLs and natural gas. The
Company's primary NGL product is propane, which is used for agricultural and
home heating in the Company's market areas. Demand and prices of propane usually
increase during the winter season and decrease during the summer season. The
Company's principal commodity, natural gas, is used primarily for heating fuel
for homes and industry, and for electric power generation. Demand and prices for
natural gas usually increase during the winter season. While the Company's gross
revenues typically increase or decrease seasonally, profitability from natural
gas processing operations is affected by the margins between the cost of natural
gas purchased and the sales prices of the NGLs extracted, which may not follow
seasonal patterns.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, Earnings Per Share ("FAS 128"). FAS
128 will change the computation, presentation and disclosure requirements for
earnings per share. FAS 128 requires the presentation of "basic" and "diluted"
earnings per share, as defined, for all entities with complex capital
structures. FAS 128 is effective for financial statements issued for periods
ending after December 15, 1997, and requires restatement of all prior period
earnings per share amounts. The Company has not yet determined the impact that
FAS 128 will have on its earnings per share when adopted.
 
     Statement of Position 96-1, "Environmental Remediation Liabilities," issued
by the American Institute of Certified Public Accountants, will become effective
for the Company in 1997. This statement establishes the timing and measurement
of accruals for environmental liabilities. The Company does not anticipate that
this standard will have a material effect on its financial condition or results
of operations.
 
UNAUDITED QUARTERLY RESULTS OF OPERATIONS
 
     The following table sets forth certain unaudited quarterly financial
information for each of the Company's last five quarters. The data has been
prepared on a basis consistent with the Company's audited consolidated financial
statements included elsewhere in the Prospectus and includes all necessary
adjustments, consisting only of normal recurring accruals that management
considers necessary for a fair presentation. The operating results for any
quarter are not necessarily indicative of results for any future period.

                                    BUSINESS
 
GENERAL
 
     The Company is an independent mid-stream energy company engaged in the
purchasing, gathering, treating, processing and marketing of natural gas and
NGLs. The Company owns and operates approximately 1,100 miles of natural gas
gathering pipelines located in the Panhandle Area with a total throughput
capacity of 383 MMcf/d and two interconnected natural gas processing plants with
a total NGL production capacity of 490 Mgal/d. CNG provides essential services
to natural gas producers in the Panhandle Area by (i) connecting the producers'
wells to the Company's gathering systems, (ii) treating the producers' natural
gas to ensure that it meets pipeline specifications, (iii) transporting the
natural gas from the wellhead to CNG's processing plants where NGLs are
extracted from the natural gas stream and (iv) providing access for the natural
gas and NGLs to various markets in the CNG Market Area of the United States. The
April 1996 and January 1997, editions of "Hart's Report on Gas Customer
Satisfaction" published by Hart Publications, Inc. reported that CNG was rated
the most preferred natural gas purchaser in surveys of natural gas sellers. The
Company markets on-system gas, as well as off-system gas, to utilities,
end-users, other marketers and pipeline affiliates.
 
   
     From 1985 through 1990, CNG's activities were primarily limited to
marketing off-system gas. Concurrent with the evolving deregulation of the
natural gas industry, the Company began to acquire natural gas gathering systems
and processing plants to complement its marketing business. Since 1990, the
Company has completed approximately $64 million of acquisitions and system
expansion projects. During March 1997, CNG's average gathering system throughput
was 108 MMcf/d and average processing plant throughput was 135 MMcf/d. The
Company's NGL production for March 1997, averaged 281 Mgal/d. Over the three
years ended December 31, 1996, the Company's daily natural gas throughput has
increased 92%. Primarily as a result of this growth, the Company's EBITDA (as
defined in the Glossary) has increased to $9.5 million in 1996 from $1.7 million
in 1994. For the three months ended March 31, 1997, the Company's EBITDA was
$3.7 million.
    
 
   
     The Company's principal assets are located in the Panhandle Area, which is
a major natural gas producing area with significant long-lived natural gas
reserves. CNG's Beaver Plant and Beaver Gathering System were acquired in 1990
from El Paso Natural Gas Company and currently consist of approximately 300
miles of natural gas gathering pipelines, a 65 MMcf/d cryogenic processing plant
and a 40 MMcf/d propane refrigeration plant yielding NGL production of 215
Mgal/d. The Beaver Plant is interconnected with the Company's Mocane Plant,
which was acquired from affiliates of Conoco, Inc. and Chevron USA, Inc. in
1995. The Mocane Plant consists of two refrigerated lean oil absorption plants
with a combined demonstrated capacity of 200 MMcf/d of natural gas and 280
Mgal/d of NGLs, approximately 140,000 barrels of underground NGL storage and a
6,700 barrel per day NGL fractionator. During the first half of 1996, the
Company acquired approximately 800 miles of gas gathering assets located
throughout the Texas panhandle in three separate transactions. These gathering
assets were acquired for approximately $20.2 million from subsidiaries of Enron
Corporation.
    
 
     Although the Company's principal growth in recent years has been derived
from its gathering and processing operations, the Company's sale of off-system
gas, which does not enter its gathering or processing facilities, remains a
significant portion of its business. In 1996, revenue from the sale of
off-system gas accounted for approximately 53% of the Company's total operating
revenue. The Company marketed the off-system gas of over 70 producers via 15
interstate and intrastate pipelines during 1996. The Company's entry into and
continued participation in the off-system gas business has relied upon federal
regulations mandating the delivery of third-party natural gas by interstate
pipelines. A material change in such regulations could adversely affect the
Company's off-system gas operations. See "Risk Factors -- Dependence on
Third-Party Pipelines" and "Business -- Government Regulations."

BUSINESS STRATEGY
 
     The Company's business strategy is to achieve sustainable growth in cash
flow and earnings by (i) acquiring and constructing natural gas gathering
systems and processing plants with excess capacity which complement CNG's
marketing operations, (ii) improving the profitability of the Company's existing
systems and plants by increasing their utilization and efficiency and (iii)
expanding its energy marketing services and sales volumes by offering natural
gas producers and purchasers flexible contract terms, value-added services and
other favorable arrangements.
 
     Expansion of Facilities. The Company seeks to acquire or make investments
in projects that complement its existing systems or allow it to expand into new
strategic areas and provide enhanced marketing opportunities. These investments
typically include natural gas gathering, processing, treating or fractionation
assets. By acquiring assets with unused capacity, the Company has established
significant operating leverage in the Panhandle Area. As a result, the Company
can gather and process additional natural gas through its existing systems at
incrementally higher rates of return. In addition to acquiring or constructing
new facilities in the Panhandle Area, CNG will continue to evaluate
opportunities in new operating areas where the Company believes it can establish
a competitive marketing advantage, allowing the Company to increase the wellhead
prices of natural gas paid to producers and provide value-added services.
 
   
     In implementing this strategy, CNG has completed approximately $64 million
of acquisitions and system expansion projects since 1990. The Company believes
that its acquisition track record and demonstrated ability to complete
transactions with large pipeline companies and other sellers strengthen its
ability to compete for future acquisitions. In addition, the Company believes
that its seasoned management team allows it to assess and evaluate acquisition
opportunities and integrate acquired assets into its existing operations.
    
 
     Set forth below is a summary of the Company's significant acquisitions and
construction projects:

     Improving the Profitability of Existing Facilities. The Company seeks to
maximize the profitability of its operations by (i) increasing natural gas
throughput and processing levels, (ii) directing natural gas throughput to a
particular Company-owned gas processing plant that maximizes product yields
and/or margins, (iii) investing in assets that enhance product value and (iv)
controlling operating and overhead expenses. In order to maintain or increase
natural gas throughput and processing volumes, the Company obtains additional
natural gas supplies for its facilities by connecting new wells to the Company's
gathering systems, purchasing and integrating gathering systems into the
Company's existing operations and entering into contractual natural gas supply
arrangements with producers or other gatherers.
    
 
                                       25
<PAGE>   28
 
     The opportunity to connect new wells to the Company's gathering systems is
primarily affected by the level of drilling activity near such gathering
systems. The Panhandle Area is within one of the most prolific natural gas
producing regions in the continental United States and continues to attract
significant exploration activity. Although the Company owns no oil and gas
reserves, the independent engineering firm of Lee Keeling & Associates estimates
that the leases and wells currently under contract with the Company have
approximately 700 Bcf of proved, producing natural gas reserves. The Company
believes it has sufficient gathering and processing capacity to capitalize on
the Panhandle Area's development.
 
     By maintaining geographically-focused operations, the Company believes it
is able to control operating and overhead expenses. Furthermore, the location
and strategic nature of CNG's natural gas gathering systems and processing
plants allow the Company to maximize NGL yields and product returns by directing
natural gas between its Beaver and Mocane Plants. For example, under current
market conditions, CNG seeks to maximize the flow of natural gas through the
Beaver cryogenic processing plant, thereby allowing the Company to realize
greater volumes of NGLs from the natural gas stream and enhance the total value
of its on-system gas throughput.
 
     Expanding Energy Marketing Services and Sales Volumes. CNG is a marketer of
natural gas and NGLs. The Company plans to expand its energy marketing
activities by continuing to offer creative, flexible contract terms that satisfy
the objectives of producers at the wellhead and purchasers in the marketing of
natural gas. By offering flexible contract terms and using a portfolio approach
to marketing natural gas, CNG has been able to substantially increase its
on-system gas and NGL volumes. The Company also seeks to increase its off-system
marketing. In addition, the Company intends to expand into the sale of electric
power to wholesale customers and industrial and commercial end-users.
 
     The Company markets and sells natural gas primarily in the CNG Market Area.
The Company's gathering systems and processing plants are located in an area
where many interstate pipelines converge, allowing it to take advantage of
locational differences in natural gas prices. CNG provides a full range of
services including risk management, storage, transportation, scheduling and
peaking requirements to purchasers of the Company's marketed natural gas. The
Company's natural gas marketing operations are substantially enhanced by its
ability to market natural gas gathered and processed by the Company.
Furthermore, CNG's portfolio approach to marketing allows it to offer producers
and purchasers optimum flexibility with respect to pricing, contract terms and
volumes. By aggregating large volumes of natural gas and maintaining the
flexibility to sell into different markets, CNG has been able to maximize sales
prices by selling to purchasers who are willing to pay a premium for large,
reliable quantities of natural gas.
 
     The Company also markets NGLs produced at its plants to wholesalers and
end-users. The Company's NGL marketing strategy is to increase sales to
end-users and to expand its NGL marketing operations into the purchase and sale
of third-party NGLs.
 
     The Company is currently creating the staffing and operating infrastructure
necessary to market electric power in the CNG Market Area to wholesale customers
and industrial and commercial end-users in accordance with anticipated
nationwide state-by-state deregulation. The Company believes that it may have a
market for electric power with its existing natural gas industrial and
commercial end-user customers. During 1996, the Company applied for and received
a power marketing certificate from the FERC, permitting it to sell wholesale
electric power at market-based rates pursuant to the Federal Power Act. The
Company believes its expertise in marketing natural gas in a deregulated
environment, its expanding customer base and its firm supplies of natural gas
and NGL products will allow it to compete effectively in this emerging market.
 
   
RECENT DEVELOPMENTS
    
 
   
     In July 1997, the Company completed the acquisition of the Spearman Plant
located in Ochitree County, Texas, for a purchase price of approximately $1.0
million. The Spearman Plant was shut-down in 1994 and has remained idle since
that time. The current maximum throughput of the Spearman Plant is estimated to
be approximately 50 MMcf/d utilizing a refrigerated lean-oil absorption process,
producing approximately 86 Mgal/d of NGLs. The Company believes that it will be
able to utilize the Spearman Plant for processing natural gas the Company
gathers through its nearby Spearman gathering system which is part of the Texas
Gathering Assets.
    
 
                                       26
<PAGE>   29
 
   
     In July 1997 the Company purchased from Conoco and its affiliate a 36%
interest in the Laverne Plant for a purchase price of $2.9 million. Prior to the
Laverne Plant Acquisition, the Company had acquired approximately 17% of the
plant for $1.4 million and presently owns approximately 53% of the Laverne
Plant. Concurrent with the Laverne Plant Acquisition, certain litigation between
the Company and the Conoco affiliate was settled. See "Business -- Legal
Proceedings." The Company's interest in the Laverne Plant is held by Continental
Laverne Gas Processing, L.L.C., an Oklahoma limited liability company which was
formed in May 1997, for the purpose of acquiring interests in the Laverne Plant.
    
 
   
     The Laverne Plant consists of a 200 MMcf/d cryogenic gas processing
facility, complete with liquid fractionation capability and above-ground
storage. The Laverne Plant straddles GPM Gas Corporation's Laverne natural gas
gathering system. Natural gas production feeding the Laverne Plant originates
from the Mocane-Laverne field. The plant is located approximately eight miles
east of the Beaver Plant. Current throughput at the Laverne Plant is
approximately 70 MMcf/d, yielding approximately 180 Mgal/d of NGLs. Due to the
proximity of the Laverne Plant to CNG's other assets and its substantial
underutilized capacity, the Company believes that the Laverne Plant will enhance
the Company's existing operations in the Panhandle Area.
    
 
GATHERING AND PROCESSING
 
     The Company's natural gas gathering and processing activities include
contracting to purchase natural gas supplies, operating and maintaining a system
of gathering pipelines that connect these natural gas supplies to transport
lines or natural gas processing plants and operating and maintaining processing
plants linked to its gathering systems.
 
     Purchasing. In 1996, the Company purchased natural gas from over 75
suppliers, ranging from major producers to small independent companies primarily
in the Panhandle Area. The Company's natural gas throughput in its gathering
systems and processing plants is generally supplied by producers pursuant to
long-term contracts (i.e., contracts in excess of one year). In arranging new
purchase contracts, the Company submits to the producer an offer to purchase the
natural gas from the prospective acreage. The producer typically evaluates
various offers based upon the purchase price and other contract provisions, line
pressure, the time period required for well connection and the gathering
company's reputation for service and reliable marketing. The Company believes
that its flexibility in negotiating contract terms, prompt connection of wells,
reliable performance under its contracts and strong overall relationships with
producers provide it with an important competitive advantage in the acquisition
of new natural gas supplies.
 
     The terms of the Company's natural gas purchase contracts are determined
based upon negotiations with producers, competition and the desire to maximize
the value to be realized from its gathering and processing systems. The Company
purchases a majority of its on-system gas supplies pursuant to long-term
contracts that require producers to dedicate all natural gas produced from
designated properties. The pricing of these producer contracts is generally not
fixed, however, and follows the market price.
 
   
     The Company's on-system gas contracts with producers may be classified as
(i) processing contracts, (ii) purchase contracts or (iii) gathering contracts.
In March 1997, the Company contracted 14% of its natural gas volumes pursuant to
processing contracts, 47% pursuant to purchase contracts (sometimes with
processing included) and 39% under gathering contracts (sometimes with
processing included). Under processing contracts, the Company agrees to process
the raw natural gas from the wells on behalf of the producers and to allocate
the NGLs recovered and the residue natural gas to each well connected to its
gathering system. The Company retains a percentage of the value of the NGLs
extracted net of plant fuel and NGL shrinkage. The producer bears a share of the
cost of NGL extraction in return for a share of NGL revenue. These processing
contracts are typically on a "keep-whole" basis, where the Company must
reimburse the producer for the fuel and shrinkage.
    
 
                                       27
<PAGE>   30
 
     Under a purchase contract, the Company generally pays for natural gas
received at the wellhead or at some other delivery point. The Company then
usually resells the natural gas after processing the natural gas for its own
account at its processing facilities. The Company derives a gross margin equal
to the difference between sale proceeds of both the NGLs and the residue natural
gas and the cost of the natural gas purchased at the wellhead.
 
     In (i) gas purchase, (ii) gathering contracts with processing and (iii)
keep-whole processing contracts, operating margins are enhanced by maximizing
the value of the NGLs extracted from the natural gas stream and minimizing the
operating costs which the Company incurs during processing and gathering.
Margins under these contracts can be affected by decreases or increases in NGL
prices or increases or decreases in natural gas prices.
 
     Gathering. Under gathering contracts, the Company typically gathers natural
gas on behalf of a producer from various wellheads for redelivery to specific
pipeline interconnection or redelivery points. The producer is charged a
gathering fee plus a fuel charge for such gathering services. Generally, the
producer will pay the Company a discounted gathering fee in exchange for the
Company retaining some or all of the extracted NGLs.
 
     In the first half of 1996, the Company acquired certain assets in three
separate transactions from subsidiaries of Enron Corporation. As modified by the
Company and then integrated into the Company's business, these assets
collectively comprise the Texas Gathering Assets, which include 800 miles of
gathering pipeline and connect the Beaver and Mocane Plants to new gas supplies
via third-party interstate pipelines.
 
     Natural gas from the Company's Texas Gathering Assets is transported to the
Company's processing plants through interstate pipelines, primarily NNG and TW.
Approximately 60% of the natural gas transported by NNG and TW for the Company
is subject to firm transportation agreements which obligate the pipelines to
give priority to the transportation of the Company's natural gas. The Beaver
Gathering System delivers on-system gas to the Company's processing plants. In
addition, natural gas may be transported to the Company's processing plants
through interruptible transportation agreements with pipelines and third-party
natural gas gatherers. Interruptible transportation agreements require the
pipelines to deliver natural gas on a "first-come, first-serve" basis after
satisfaction of commitments under firm transportation agreements.
 
     Processing. The Company owns and operates two interconnected natural gas
processing plants, one of which is connected to the Beaver Gathering System.
These processing plants complement the Company's gathering operations by
enabling the Company to offer to its producers the option of wellhead purchase
or processing contracts. The sale of NGLs contributes materially to the overall
earnings of the Company because of the added value from NGL extraction. In
addition, natural gas processing complements and diversifies the earnings
derived from natural gas sales. The Company's processing plants at present have
excess capacity which, if increased natural gas supplies can be obtained, can be
utilized to increase Company revenues with a minimal increase in operating
costs. Management of the Company will attempt to obtain the natural gas supplies
necessary to utilize such excess capacity and benefit by the resultant
efficiency.
 
     The Company's Beaver and Mocane Plants extract NGLs and remove water vapor,
solids and other contaminants contained in the natural gas stream. Each of these
plants is capable of recovering substantially all isobutane, normal butane and
natural gasoline components from the natural gas stream. Propane and ethane are
the Company's two primary NGL products. The Beaver Plant, due to its cryogenic
process, is able to extract a higher percentage of NGLs than the Mocane Plant.
 
     The location of the Company's processing plants provide access to nearby
markets for the sale of NGLs, thus reducing transportation costs. The Company
believes its processing plants provide it with a competitive advantage in the
acquisition of natural gas supplies. Much of the Company's natural gas
processing capacity has ethane rejection capability, which allows the Company to
optimize margins if ethane prices decline significantly relative to natural gas
prices. The Company's two processing plants are interconnected.
 
     Beaver Plant. The Beaver Plant was built in 1961. When acquired by CNG in
1990, the Beaver Plant consisted of a 40 MMcf/d design capacity refrigeration
plant, capable of extracting approximately 40% of the propane, nearly all of the
butane and gasoline, and virtually none of the ethane from the inlet natural gas
stream. Average throughput was less than 10 MMcf/d prior to the Company's
acquisition of the facility. In 1992, the Company purchased and relocated a 65
MMcf/d cryogenic processing plant to the Beaver Plant.
 
                                       28
<PAGE>   31
 
The added facility chills natural gas to -155 degrees Fahrenheit and separates
the natural gas from the NGLs condensed at the low temperatures. The Beaver
cryogenic processing plant currently recovers 95% of the propane, 70% of the
ethane and nearly 100% of the heavier butane and natural gasoline from the
natural gas stream.
 
     The design of the Beaver Plant allows for relatively fuel-efficient,
low-pollution extraction of a high volume of NGLs from natural gas. The combined
cryogenic and refrigeration facilities have a processing capacity of 105 MMcf/d
of inlet natural gas and 215 Mgal/d of extracted NGLs. The Beaver Plant's
average throughput for March 1997 was 70 MMcf/d yielding 180 Mgal/d of NGLs. The
Beaver Plant and gathering system has over 28,000 horsepower of gathering and
processing compression capability. The cryogenic facilities typically run at
full capacity while the refrigeration unit is typically idle.
 
     The NGLs produced consist of a mixture (commonly known as "Y-Grade") of
ethane, propane, isobutane, normal butane and natural gasoline. The Y-Grade
mixture is delivered into an NGL pipeline operated by an affiliate of Koch
Industries, Inc. which is connected to the Beaver Plant.
 
     Mocane Plant. The Mocane Plant was built in 1959, was partially updated in
1985 and was acquired by CNG in early 1995. The Mocane Plant is located about 13
miles northwest of the Beaver Plant. The Mocane Plant has a demonstrated inlet
natural gas capacity of 200 MMcf/d and is designed to extract up to 280 Mgal/d
of NGLs. The Mocane Plant's average throughput for March 1997 was 65 MMcf/d,
yielding 101 Mgal/d of NGLs. Prior to the Company's acquisition of the Mocane
Plant in early 1995, recent historical throughput averaged less than 40 MMcf/d.
 
     The Mocane Plant uses refrigeration and lean oil absorption processes to
extract NGLs. Propane recovery is approximately 85% and ethane recovery is
approximately 25% with nearly 100% of the heavier butane and natural gasoline
being recovered. The Mocane Plant has over 7,500 horsepower of compression used
in the NGL extraction process.
 
     Y-Grade produced at the Mocane Plant may be sold and delivered to NGL
pipelines operated by affiliates of Koch Industries, Inc. and Mapco, Inc.
Alternatively, the Company may fractionate the NGLs into the various components
at its on-site fractionation facility and deliver these NGLs to purchasers via
truck racks. The Mocane Plant has fractionation capacity of 281 Mgal/d. The
Mocane facility can produce propane, isobutane, normal butane, natural gasoline
and a mixture of ethane and propane.
 
SALES AND MARKETING
 
     Natural Gas Marketing. The Company markets natural gas to local
distribution companies ("LDCs"), marketing affiliates of pipeline companies,
electric utilities, various business and industrial end-users and other natural
gas marketers throughout the CNG Market Area. A portion of the natural gas which
the Company markets is produced in the Panhandle Area and is transported from
the Company's plants through pipeline interconnections with ANR Pipeline Company
("ANR"), Williams Natural Gas Company ("WNG"), NNG and Colorado Interstate Gas
Company ("CIG"). In addition, the Company purchases and resells off-system gas
on numerous pipeline systems located throughout the CNG Market Area.
 
     The Company has multiple pipeline delivery connections, which it believes
allow it to negotiate favorable spot sales contracts and transportation rates
and to avoid curtailment of natural gas deliveries. Due to the flexibility
derived from multiple delivery points, the Company believes that the loss of any
of its markets on a particular pipeline would not have a material adverse effect
on the Company. The Company's facilities are located in an area where many
interstate pipelines converge, allowing it to take advantage of locational
differences in natural gas prices.
 
     During the year ended December 31, 1996, the Company delivered natural gas
to approximately 125 customers located in 12 states. In 1996, the Company
delivered an average of approximately 224 MMcf/d (81.7 Bcf of natural gas for
the year) and had natural gas sales revenues of approximately $209 million. No
one customer accounted for more than 10% of total natural gas sales revenues
during 1996.
 
     During 1994 and 1995, the Company experienced average daily natural gas
sales of 142 MMcf/d and 165 MMcf/d, respectively. In 1996, the Company's natural
gas sales averaged 224 MMcf/d and during the first quarter of 1997, this average
increased to 280 MMcf/d. Sales growth in 1996 and 1997 has resulted
 
                                       29

largely from CNG's hiring of six additional marketing representatives during the
period from May 1, 1996 to the present. The Company plans to hire additional
representatives.
 
     By aggregating large volumes of natural gas and maintaining the flexibility
to sell into different markets, CNG has been able to maximize sale prices by
selling to customers who are willing to pay a premium for large, reliable
quantities of natural gas. Accordingly, the Company expects to continue to
receive greater value than the commodity spot price for its delivered natural
gas.
 
     The Company sells natural gas under sales agreements which may be
classified by (i) the duration of the contract, (ii) pricing terms and (iii) the
nature of the delivery obligations. "Term" contracts have a duration in excess
of one month, "spot" contracts have a duration of one month or less and
"peaking" contracts apply during short periods of high demand. The Company sells
natural gas at "fixed" prices or at "index" prices which vary on a
month-to-month basis with market conditions. Under "baseload" contracts the
Company is required (subject to extremely limited exceptions) to deliver a
specific volume of natural gas, while under "best efforts" contracts delivery
obligations may be suspended at the option of the Company or the purchaser. Due
to varying market conditions, the "mix" of the Company's sales agreements vary
substantially from time to time.
 
     Transportation. The Company arranges for transportation of the natural gas
it markets from the supplier's point of receipt to the sales customer's delivery
point. To facilitate the transportation of its natural gas the Company must
schedule, nominate and monitor transportation availability on a continual basis.
The Company believes that its knowledge of the pipeline network within the CNG
Market Area is an important element in its success as a natural gas marketer.
This allows the Company to provide its suppliers with multiple outlets for their
natural gas and, in times of changes in demand or supply due to weather or other
factors, to route natural gas to areas where higher sales prices may be
achieved. In an effort to improve profit margins, the Company attempts to reduce
transportation charges by taking advantage of its broad array of transportation
arrangements and by negotiating Capacity Release, storage and competitive
transportation discounts.
 
     The Company transports natural gas on interstate pipelines under
interruptible and firm transportation agreements. Under interruptible
transportation agreements, a pipeline is usually obligated to transport on a
non-discriminatory basis up to a specified maximum quantity of natural gas,
subject to available capacity. In return, the Company pays a transportation fee
based on the quantity of natural gas actually transported. An interruptible
transportation agreement may provide the customer with priority over other
interruptible shippers based on the rate paid and subject to the availability of
capacity not utilized by parties shipping under firm transportation agreements.
As of December 31, 1996, the Company had over 150 interruptible transportation
contracts. The majority of off-system gas purchased and sold by the Company is
transported under interruptible transportation arrangements.
 
     Under firm transportation agreements, a pipeline is obligated to transport
up to a specified maximum quantity of natural gas without interruption, except
upon the occurrence of a force majeure event. Certain of the Company's
customers, including LDCs and electric utilities, and some of the Company's
long-term supply contracts require dependable transportation services provided
under firm transportation agreements. Some customers who purchase natural gas
from the Company transport such natural gas under their own transportation
arrangements, while other customers require or allow the Company to arrange for
such transportation services on their behalf.
 
     Under contractual arrangements with pipelines, the Company is required to
balance its deliveries and receipts from each pipeline on a monthly or daily
basis. The pipelines are authorized to impose "imbalance penalties" in the event
that the Company's deliveries or receipts from any pipeline are not balanced on
a monthly or daily basis. These penalties are typically quite severe. In
addition, the Company may be required to purchase or sell natural gas at
unacceptable prices in the event it has not accurately balanced its deliveries
or receipts from the pipeline (i.e. it must purchase natural gas to make up
deficient volumes or sell natural gas to reduce excess volumes). Historically,
the Company has not incurred any significant "imbalance penalties" or sustained
other significant losses as a result of pipeline imbalances.
 
     Due to regulatory changes resulting from Order 636 of the FERC, the
availability of firm transportation has increased, while the availability of
interruptible transportation on certain pipelines has decreased. In
 
                                       30
<PAGE>   33
 
particular, Order 636 permits current holders of pipeline firm transportation
rights, generally LDCs and large end-users, either to enter into Capacity
Releases of dedicated capacity with replacement shippers or to turn that
capacity back to the pipeline to be posted on an electronic bulletin board for
sale. Typically, LDCs sell Capacity Release during periods of low demand and
compete with released capacity by other LDCs or the pipeline's unsubscribed
capacity. As a result, the Company is often able to purchase Capacity Release at
a discount from posted rates.
 
   
     NGL Marketing. The Company presently sells NGLs primarily to wholesale
markets with some sales in the local retail market. The Company has recently
hired an NGL marketer with the intent of realizing higher margins on NGLs
through increased sales to the retail market and increasing the marketing of
third-party NGLs. Generally, prices for NGLs tend not to vary directly with
natural gas prices, but more closely follow the prices of crude oil derivatives.
Processing margins increase when natural gas prices are lower in relation to NGL
prices. The Company had NGL sales of approximately $34.8 million in 1996 on NGL
average volumes of 276 Mgal/d.
    
 
     NGLs are typically used as petrochemical feedstocks, petroleum refinery
blendstocks or fuel. Petrochemical plants use ethane, propane, butane and
natural gasoline in the production of ethylene, which is used in the manufacture
of plastics, building materials, automobile antifreeze and other products.
Refineries use normal butane and isobutane as motor fuel additives. Propane has
agricultural applications and is used as fuel for household consumption,
vehicles and industrial heaters and boilers.
 
     As feedstock, demand for NGLs is influenced by the demand for the end
products in which they are used. Also, the demand for normal butane and
isobutane, which are important feedstocks for the production of the oxygenate,
methyl tertiary butyl ether ("MTBE"), is expected to increase as demand for MTBE
increases in gasoline production. The required use of oxygenates in motor
gasoline under the Clean Air Act Amendments of 1990 in many parts of the United
States is expected to increase demand for MTBE. Seasonal requirements of
purchasers using NGLs as a fuel source also affect demand. NGL production is
dependent upon the supply and NGL content of domestic natural gas. The market
price of NGLs relative to natural gas affects the volume of natural gas
processed and the NGLs extracted from the natural gas. Certain NGLs are produced
outside North America and imported by ship, which may from time to time affect
NGL prices.
 
     Risk Management Activities. The Company uses risk management tools to
reduce commodity price risk for (i) purchases of natural gas to replace fuel and
shrinkage in connection with processing operations and (ii) its NGL and natural
gas sales. With respect to fuel and shrinkage for processing operations the
Company examines the prevailing price environment on an ongoing basis to
determine if opportunities exist to lock-in prices for replacement natural gas
at levels acceptable to the Company. The Company's management is responsible for
monitoring the price environment for replacement natural gas and makes any
decisions necessary to implement the Company's hedging strategies.
 
     The Company employs several procedures to manage its risk with respect to
the purchases and sales of natural gas. The Company's principal strategy is to
balance purchases and sales of natural gas on a daily and monthly basis. This
means on any given day or in any given month the Company has commitments to
purchase and sell approximately the same volume of natural gas. This strategy is
accomplished through active management and monitoring of natural gas supply and
sales through the Company's natural gas marketing department.
 
     A second strategy employed by the Company to manage risk is to enter into
contracts for the "back-to-back" purchase and sale of natural gas. Under this
strategy, the Company enters into natural gas purchase contracts and natural gas
sales contracts for a corresponding volume of natural gas. The Company thereby
locks in its profit and also locks in a supply of natural gas in order to assure
performance under the applicable sales contract.
 
     Finally, the Company enters into other hedging transactions with respect to
its fixed price purchases and sales of natural gas, which constitute less than
10% of its total purchases and sales. These transactions include futures
contracts, swaps and basis agreements and other arrangements common in the
financial markets. The Company consistently has hedging positions to cover
substantially all of its purchases and sales under fixed price agreements.
 
                                       31
<PAGE>   34
 
     The Company does not use hedging transactions for speculative purposes. The
Company has, however, on certain occasions taken open positions on carefully
selected arbitrage opportunities. While these occasions have been relatively few
and are carefully reviewed by the Company's management, the Company believes
that the competitive information it obtains from its energy marketing activities
allows it to take advantage of certain opportunities in the market.
 
     The Company's management oversees all hedging activity of the Company. A
daily book on all positions is maintained and daily and monthly reports are
given to management. See Note 12 to the Notes to Consolidated Financial
Statements of the Company included herein.
 
     In addition to the risk associated with price movements, credit risk is
also inherent in the Company's risk management activities. Credit risk relates
to the risk of loss resulting from the nonperformance of a counterparty of its
contractual obligations. The Company maintains credit policies with regard to
counterparties that the Company believes significantly minimize overall credit
risk. These policies include the thorough review of potential counterparties'
financial condition, collateral requirements under certain circumstances,
monitoring of net exposure to each counterparty and the use of standardized
agreements which allow for the netting of positive and negative exposures
associated with each counterparty.
 
     Electric Power Marketing. The Company formed Continental Energy Services,
L.L.C. ("CES") in 1996 to pursue electric power marketing opportunities that are
being created as the domestic electric power industry becomes increasingly
deregulated pursuant to the Energy Policy Act of 1992 (the "Energy Policy Act")
and certain actions taken by the FERC (including implementation of wholesale
open access under Order 888) and public utility commissions in various states.
Just as the Company provides aggregation and marketing services for natural gas
producers and consumers, CES intends to provide similar services in a
deregulating domestic electric industry.
 
     CES received authorization from the FERC in December 1996 to purchase, sell
and market wholesale electric power and engage in other energy-related
transactions and to charge market-based rates for such services and
transactions. CES initially intends to market electric power to electric
utilities, municipalities and electric cooperatives on a wholesale basis.
 
     In the future, if the power industry continues to deregulate and subject to
state and federal regulations, CES also intends to pursue the direct marketing
of power to existing industrial and commercial natural gas customers of the
Company in states which permit such activities. There is no guarantee that the
states or the federal government will adopt programs permitting such activities
or that such programs will be adopted on terms beneficial to CES. If adopted,
however, these programs are anticipated to allow CES to market electric power
directly to industrial and commercial end-users while using the utilities,
municipalities and electric cooperatives solely to generate and transmit power
to these end-users, much like the Company markets natural gas to LDCs and
end-users using the pipelines for transportation services only. CES also expects
to offer a variety of risk management products and services to generators and
consumers including futures, options, swaps and basis agreements and other
financial instruments.
 
     CES has not, as yet, entered into any contracts or conducted any
substantive activities. The timing, manner and extent to which the power
industry will deregulate, with respect to both wholesale power marketing and
retail direct access, is extremely uncertain. Even if the power industry
continues to deregulate in a manner beneficial to CES, there can be no assurance
that the operations of CES, when and if commenced, will be profitable.
 
CAPITAL INVESTMENT PROGRAM
 
   
     Capital spending by the Company is expected to reach $11.5 million in 1997.
Approximately $5.3 million is expected to be spent in connection with the
acquisitions of the Spearman Plant and the Laverne Plant. See
"Business -- Recent Developments." The remainder will be spent on various
expansions of the Company's gas gathering systems to accommodate new gas supply
development.
    
 
FACILITIES
 
     Gathering Systems and Processing Plants. As of June 1, 1997, the Company
had approximately 1,100 miles of natural gas gathering pipelines, two natural
gas processing plants, each of which has extraction
 
                                       32

equipment and one of which has fractionation equipment and 49 compressor units
located at 18 field stations and the two plant sites.
 
     The following table provides information concerning the Company's natural
gas processing plants and gathering systems:

     The Company owns approximately 43 acres of land at its Beaver Plant site
and an additional 40 acres at its Mocane Plant site. While this real property is
necessary in order to operate its Beaver and Mocane Plants, it does not
contribute significantly to the value of the Company.
 
     The Company's gas processing plants are fed directly by a network of low
and intermediate pressure steel and polypipe gas gathering pipelines. The Beaver
Gathering System consists of approximately 300 miles of pipelines connecting
over 100 wells for ultimate delivery to the Company's Beaver and Mocane Plants.
Approximately 22% of the Beaver and Mocane Plants' throughput originates from
the Beaver Gathering System. The Company's Texas Gathering Assets extend for
approximately 800 miles across the northern Texas Panhandle providing
substantial gathering exposure along the western edge of the Anadarko Basin,
south of its existing processing plants. Approximately 500 wells are connected
to the Texas Gathering Assets for redelivery to the interstate pipelines of
either NNG or TW. The Texas Gathering Assets, which are steel pipelines, operate
at low pressures.
 
     The Company installed two pipelines connecting the Mocane Plant to the
Beaver Plant in 1995. These pipelines allow the Company to optimize processing
capacity utilization by shifting raw and processed natural gas between the
Beaver and Mocane Plants. In addition, the Company has constructed approximately
27 miles of residue interconnect line, connecting the Beaver Plant to the ANR,
WNG and CIG interstate pipelines, thus expanding the markets for the Company's
on-system gas.
 
     The Company's operations in the Panhandle Area consist of the Beaver and
Mocane Plants, natural gas gathering systems, compression equipment, NGL
storage, fractionation and truck terminal facilities. The Company believes the
Panhandle Area has favorable production, supply and market access
characteristics. The Panhandle Area is one of the most prolific natural gas
producing regions in the continental United States. Production is obtained from
several geologic formations. Natural gas fields in the area have produced for
many years and currently produce at stabilized low rates of decline that
indicate substantial reserves. Estimates by an independent engineering firm, Lee
Keeling & Associates, attribute approximately 700 Bcf of natural gas to the
Company's contracted leases and/or wells as of January 1, 1997.
 
     Compression and Storage Facilities. In connection with the operation of its
gathering systems, the Company operates 49 compressor units located at 18 field
stations and two plant sites with approximately 44,000 horsepower of natural gas
compression. Compressors are used to boost natural gas produced and gathered at
low field pressure to higher pipeline pressures. Approximately 30% of the
Company's compression capacity is leased under various capital lease agreements.
Under such capital lease agreements, the Company makes approximately $1.8
million per year in payments. The terms under such capital leases range from
1998 to 2003 at which time the Company has an option to purchase (generally at a
nominal price) the leased equipment. The Company continues to enter into capital
lease agreements for compression and other natural gas processing equipment.
Under its credit facility, the Company is permitted to incur capital lease
obligations which require incremental annual payments of up to $1 million per
year.
 
                                       33
<PAGE>   36
 
     The Company has approximately 140,000 barrels of underground NGL storage
capacity at the Mocane Plant. Two of the five underground storage caverns
(amounting to approximately 20% of the total storage capacity located at the
Mocane Plant) are currently operational. The Company is currently evaluating the
economic feasibility of placing the remaining storage caverns in operation.
 
   
     Corporate Offices. The Company leases its Tulsa, Oklahoma headquarters
under a commercial office lease covering approximately 20,000 square feet,
expiring in September 2002. The annual rental payments are approximately
$214,000.
    
 
OPERATIONAL RISKS AND INSURANCE
 
     The Company's operations are subject to potential hazards incident to the
gathering, processing, separation and storage of natural gas and NGLs, such as
explosions, product spills, leaks, emissions and fires. These hazards can cause
personal injury and loss of life, severe damage to and destruction of property
and equipment, and pollution or other environmental damage, and may result in
curtailment or suspension of operations at the affected facility.
 
     The Company maintains general public liability, property and business
interruption insurance in amounts that it considers to be adequate for such
risks. Such insurance is subject to deductibles that the Company considers
reasonable and not excessive. Consistent with the Company's proactive approach
to risk management, the Company's pollution liability policies not only provide
protection for sudden and accidental occurrences, but also, subject to the
policy terms and conditions, provide protection for gradual pollution incidents
occurring over time.
 
     The occurrence of a significant event for which the Company is not fully
insured or indemnified, and/or the failure of a party to meet its
indemnification obligations, could materially and adversely affect the Company's
operations and financial condition. Moreover, no assurance can be given that the
Company will be able to maintain adequate insurance in the future at rates it
considers reasonable. To date, however, the Company has maintained adequate
coverage at reasonable rates and has experienced no material uninsured losses.
 
COMPETITION
 
     The Company faces intense competition in obtaining natural gas supplies for
its gathering and processing operations and in marketing its products and
services. Principal competitors include marketing affiliates of interstate
pipeline companies, national and local natural gas gatherers and marketers of
varying sizes, financial resources and experience. Many of the Company's
competitors have capital resources and control supplies of natural gas
substantially greater than those of the Company.
 
     The Company competes against other companies in the natural gas processing
business both for supplies of natural gas and for customers to which it sells
its products. Competition for natural gas supplies is based primarily on price,
location of natural gas gathering facilities and gas processing plants, line
pressures, operating efficiency, reliability and quality producer relationships.
Competition for sales customers is based primarily on price, delivery
capabilities, reliability, price flexibility and maintenance of quality customer
relationships.
 
     CNG's fractionation business competes against other fractionation
facilities that serve local markets. Competitive factors affecting its
fractionation business include proximity to customers, quality of NGL products,
price, efficiency and reliability of service.
 
     In marketing its products and services, the Company has numerous
competitors, including marketing affiliates of major interstate pipelines, major
natural gas producers, and local and national gatherers and marketers of widely
varying sizes, financial resources and experience. Marketing competition is
primarily based upon reliability, transportation, flexibility and price.
 
GOVERNMENT REGULATION
 
     Currently, federal, state and local regulations do not materially affect
the purchase and sale of natural gas and the fees received for gathering and
processing by the Company. Therefore, except as constrained by competitive
factors and contracts, the Company has considerable pricing flexibility.
However, federal, state
 
                                       34
<PAGE>   37
 
and local laws and regulations, directly or indirectly, govern some aspects of
the operations of the Company. These laws and regulations may in the future have
a significant impact upon the Company's overall operations.
 
     In 1992, the FERC issued Order 636 which generally opens access to
interstate pipelines by requiring the operators of such pipelines to unbundle
their transportation services from sales services and allow customers to choose
and pay for only the services they require, regardless of whether the customer
purchases natural gas from such pipeline or from other suppliers. Order 636 also
requires upstream pipelines to permit downstream pipelines to assign upstream
capacity to their suppliers, and places analogous, unbundled requirements on the
downstream pipelines. This mandated access to interstate pipelines was and is of
vital importance to the Company's off-system gas business and to the delivery of
natural gas from CNG's Texas Gathering Assets to its processing plants in
Oklahoma. A change in such regulation could adversely affect these portions of
the Company's business.
 
     The FERC retains jurisdiction over the interstate transportation of natural
gas and of liquid hydrocarbons, such as NGLs and product streams derived
therefrom. The gathering and processing of natural gas for the removal of
liquids currently is not viewed by the FERC as an activity subject to its
jurisdiction. If a processing plant's primary function is extraction of NGLs and
not natural gas transportation, the FERC has traditionally maintained that the
plant is not a facility for transportation or sale for resale of natural gas in
interstate commerce and, therefore, is not subject to jurisdiction under the
Natural Gas Act of 1938 (the "NGA").
 
     The NGA exempts natural gas gathering facilities from the jurisdiction of
the FERC. Interstate transmission facilities, on the other hand, remain subject
to the FERC jurisdiction. The FERC has historically distinguished between these
two types of facilities on a fact-specific basis. The Company believes that its
gathering facilities and operations meet the current tests that the FERC uses to
determine a nonjurisdictional gathering facility status. While certain recent
cases have applied these tests in a manner supporting the Company's view that
the FERC lacks jurisdiction over its gathering facilities, these cases are,
however, still subject to rehearing and appeal. In addition, the FERC's
articulation and application of the tests used to distinguish between
jurisdictional pipelines and nonjurisdictional gathering facilities have varied
over time. While the Company believes the current definitions create
nonjurisdictional status for the Company's gathering facilities, no assurance
can be given that such facilities will remain classified as natural gas
gathering facilities and the possibility exists that the rates, terms, and
conditions of the services rendered by those facilities, and the construction
and operation of the facilities, will be subject to regulation by the FERC.
 
     There are two pending proceedings at the FERC in which parties allege that
the FERC should regulate the rates and operations of certain aspects of the
Company's business. (GPM Gas Corporation v. Continental Natural Gas, Inc.,
Docket No. CP96-495-000; Plant Owners v. Continental Natural Gas, Inc., Docket
No. CP96-577-000.) The entities initiating these proceedings allege that the use
of the Company's facilities to receive natural gas from, and deliver natural gas
to, interstate pipelines renders those facilities subject to FERC's
jurisdiction. The Company is contesting these allegations. While the Company
believes that its business is not subject to regulation by the FERC, it cannot
predict the outcome of these proceedings, nor can it predict the effect a ruling
would have on the Company's business. If the FERC issues a decision in either of
these cases that subject some or all of the Company's facilities to the FERC's
jurisdiction, the decision may limit the rates that the Company charges for its
services, may have the effect of precluding the Company from engaging in certain
transactions, or may impose other obligations on the Company which may have a
material adverse effect on the Company. Knowing violations of the NGA may result
in the imposition of fines, forfeitures or other criminal penalties; however,
the imposition of such has been extremely rare.
 
     Traditionally, the FERC has regulated the rates for gathering service
performed by interstate pipelines and their affiliates. In 1995, the FERC held
that interstate pipeline affiliates that performed gathering services could have
their rates and services deregulated. In addition, the FERC established a
two-year default (i.e., transition) period during which the new owners of
gathering facilities formerly owned by interstate pipelines would have to
provide service at the same rates and on the same terms and conditions as was
provided by the pipelines. As a result, many interstate pipelines have
transferred their facilities to gathering affiliates or sold them to
third-parties. On August 2, 1996, the United States Court of Appeals for the
District
 
                                       35
<PAGE>   38
 
of Columbia Circuit upheld the FERC's decision to deregulate gathering but
voided the two year default period. As a result, there could be numerous
additional unregulated gathering companies. Certain of those gathering companies
may compete with the Company. Notwithstanding the decision of the D.C. Circuit,
many owners of facilities acquired from interstate pipelines have committed to
continue providing service at the same rates and on the same terms and
conditions during the default period. At the expiration of these default
periods, it is possible that the cost of gathering service paid by the Company
could increase substantially. In addition, the Company (as a shipper on these
systems) could be placed at a competitive disadvantage vis-a-vis the owner of
the gathering facilities in acquiring natural gas and NGLs. It should be noted
that the Company's Texas Gathering Assets would also be free of the
FERC-mandated rate controls when their associated default period expires at the
end of 1997. Except with respect to the owners of gathering systems, the Company
does not believe that it will be affected by any action taken with respect to
the FERC's gathering policy materially differently than any other producers,
gatherers, processors or marketers with which it competes.
 
     The Company purchased the Texas Gathering Assets from subsidiaries of Enron
Corporation that were regulated by the FERC prior to the purchase. In accordance
with federal regulations, the Company agreed that it would not charge rates that
exceed the rates that Enron was charging at the time of the sale until December
31, 1997, after which time the Company will be free to set rates in accordance
with market conditions at that time, subject, however, to future state or
federal laws or regulations.
 
     Certain activities of the Company could be subject to regulation by the
Texas Railroad Commission ("RRC") pursuant to its jurisdiction over common
purchasers and natural gas utilities or its jurisdiction over the transportation
and gathering of natural gas. CNG is a "common purchaser" under Texas law. It is
not presently registered as a "gas utility" though no assurance can be given
that it will not at some future time be required to register as such.
 
     Although the RRC does not regulate the activities of the Company at this
time, the RRC has authority to regulate the volumes of natural gas purchased by
common purchasers and the rates charged for the intrastate transportation,
gathering and sale of natural gas by gas utilities in Texas. Under the Gas
Utility Regulatory Act and other Texas statutes, the RRC has the duty to ensure
that rates for the transportation, gathering and sale of natural gas are just
and reasonable and gas utilities are prohibited from charging rates that are
unreasonably preferential, prejudicial or discriminatory. The Company believes
that its activities are in compliance with applicable laws and regulations.
 
     All of the Company's pipeline operations are subject to federal safety
standards promulgated by the Department of Transportation under applicable
federal pipeline safety legislation, as supplemented by various state safety
statutes and regulations.
 
     The Company's Oklahoma operations are subject to regulation by the State of
Oklahoma. The majority of these regulations are administered by the Oklahoma
Corporation Commission ("OCC"). Any entity engaged in the business of carrying
or transporting natural gas by pipeline is declared to be a common carrier under
Oklahoma law and is prohibited from any unjust or unlawful discrimination in the
carriage, transportation or delivery of natural gas. Although Oklahoma law may
be sufficiently broad to permit the OCC to set rates and terms of service for
the transportation and delivery of natural gas involving the Company's Oklahoma
assets, the OCC has not done so to date. There can be no assurance that the OCC
will not do so in the future. Recent Oklahoma legislation prohibits entities
which gather natural gas for hire from charging any fee which is unjustly or
unlawfully discriminatory. The Company does not expect this legislation to have
any significant impact on the Company's operations.
 
     An entity carrying or transporting natural gas by pipeline which is engaged
in the business of purchasing natural gas is declared to be a common purchaser
under Oklahoma law and is required to purchase without discrimination in favor
of persons or price all natural gas in the vicinity of its lines. Ratable
purchase is required if a purchaser is unable to purchase all natural gas
offered. To date, such legislation has not had any significant effect on the
Company's Oklahoma operations.
 
                                       36
<PAGE>   39
 
     The OCC and the RCC regulate the amount of natural gas which producers can
sell or deliver to the Company. Currently, substantially all natural gas
received by the Company in its Oklahoma and Texas operations is produced from
wells for which the OCC or RCC establish allowable rates. To date, the Company
has not experienced any material reductions in available supplies due to these
regulations. Nevertheless, future regulations could materially affect the
Company's ability to purchase natural gas supplies.
 
ENVIRONMENTAL MATTERS
 
     The Company is subject to environmental risks normally incident to the
operation and construction of gathering lines, pipelines, plants and other
facilities for gathering, processing, treatment, storing and transporting
natural gas and other products. These environmental risks include uncontrollable
flows of natural gas, fluids and other substances into the environment,
explosions, fires, pollution and other environmental and safety risks. The
following is a discussion of certain environmental and safety concerns related
to the Company. It is not intended to constitute a complete discussion of the
various federal, state and local statutes, rules, regulations, or orders to
which the Company's operations may be subject. For example, the Company, without
regard to fault, could incur liability under the Comprehensive Environmental
Response, Compensation, and Liability Act of 1980, as amended (also known as the
"Superfund" law), or state counterparts, in connection with the disposal or
other releases of hazardous substances and for damage to natural resources.
Further, the recent trend in environmental legislation and regulations is toward
stricter standards, and this will likely continue in the future.
 
     The Company's activities in connection with the operation and construction
of gathering lines, pipelines, plants, storage caverns, and other facilities for
gathering, processing, treatment, storing and transporting natural gas and other
products are subject to environmental and safety regulation by federal and state
authorities, including, without limitation, the state environmental agencies and
the EPA, which can increase the costs of designing, installing and operating
such facilities. In most instances, the regulatory requirements relate to the
discharge of substances into the environment and include measures to control
water and air pollution.
 
     Environmental laws and regulations may require the acquisition of a permit
or other authorization before certain activities may be conducted by the
Company. These laws also include fines and penalties for non-compliance.
Further, these laws and regulations may limit or prohibit activities on certain
lands lying within wilderness areas, wetlands, areas providing habitat for
certain species or other protected areas. The Company is also subject to other
federal, state, and local laws covering the handling, storage or discharge of
materials used by the Company, or otherwise relating to protection of the
environment, safety and health. The Company believes that it is in material
compliance with all applicable environmental laws and regulations. The Company
periodically conducts environmental assessments of its assets and is not aware
of any material environmental problems requiring remediation. Because the
requirements imposed by environmental laws and regulations frequently change,
the Company is unable to predict the ultimate costs of compliance with such
requirements or whether the incurrence of such costs would have a material
adverse effect on the operations of the Company.
 
   
     In March 1992, an environmental site assessment of the Laverne Plant
indicated the presence of hydrocarbon contaminated groundwater underlying a
portion of the plant site. Under the direction of the Oklahoma Corporation
Commission and based on the results of a pilot remediation project, a plan has
been developed to remediate the site utilizing a biofiltration process to be
installed during the last half of 1997 at an estimated cost of $1 million. The
Company's share of this total cost is expected to be approximately $170,000. See
"Business -- Recent Developments."
    
 
EMPLOYEES
 
     As of June 1, 1997, the Company had 95 employees. Of these, 53 employees
are located in the field and provide general operational and maintenance
activities on the Company's facilities located in the Panhandle Area while the
balance are located at CNG's executive offices in Tulsa, Oklahoma, and are
engaged in gas
 
                                       37

marketing activities, plant supervision or accounting and administration. The
Company considers its relations with employees to be excellent.
 
LEGAL PROCEEDINGS
 
   
     The Company is currently a defendant in the case of Colorado Interstate Gas
Company v. Continental Hydrocarbons, Inc., et al., Case No. 93CV1894 (the
"Colorado Lawsuit"). The case as it pertains to the Company primarily involves
claims made by CIG that the Company and Continental Hydrocarbons, Inc. ("CHI"),
a former subsidiary of the Company, have improperly withheld from it proceeds
from the sale of NGLs processed by the Mocane Plant, have defamed CIG and
committed other wrongful acts, and are as a result liable to CIG for unspecified
actual and punitive damages. The Mocane Plant Sellers have also been sued by CIG
and have sought indemnity from CHI and the Company for some of the liability
they may have to CIG as well as other amounts allegedly owed them. The Company
and CHI have generally denied the allegations against them in the case and have
contended that they are owed certain amounts for the processing of natural gas.
Though impossible to estimate with any certainty, the Company believes that CIG
is seeking actual damages in excess of $3 million. The Company has reached a
settlement with the Mocane Plant Sellers which involves the Company's payment of
approximately $1.25 million plus accrued interest (on a portion of the
settlement) to the Mocane Plant Sellers. The Company had previously recorded an
accrued liability for a portion of the proceeds received from the processing of
gas through the Mocane Plant and accordingly no additional accrual is required.
    
 
     The Company has also filed a lawsuit, Continental Natural Gas, Inc. v.
Colorado Interstate Gas Company, Case No. 96-CV-0041-BU (the "Oklahoma
Lawsuit"), in the United States District Court for the Northern District of
Oklahoma against CIG. The Company's complaint alleges constructive fraud in
connection with negotiations between the Company and CIG in the first part of
1995 for natural gas processing and gathering in the area surrounding the Mocane
Plant. In general, the Company alleges that CIG misled it and thereby precluded
the Company from offering a bid on certain compression services ultimately sold
by CIG to its subsidiary, CIG Resources Company.
 
     The Company is at various times a party to additional claims and involved
in various other litigation and administrative proceedings arising in the normal
course of business. The Company believes it is unlikely that the final outcome
of any of the claims, litigation or proceedings discussed above to which the
Company is a party would have a material adverse effect on the Company's
financial position or results of operations; however, due to the inherent
uncertainty of litigation, the Company cannot give assurance regarding the
effect on the Company of an adverse resolution of any particular claim or
proceeding.

(1) Term expires upon earlier of 90 days after termination of the named person's
     employment agreement or February 28, 2006.
    
 
   
(2) Assumes 5% annual increase in stock price over term of option which is
    assumed to expire on March 31, 2000. Exercise of option is subject to the
    Company achieving certain specified annual financial performance goals.
    
 
   
(3) Assumes 10% annual increase in stock price over term of option which is
    assumed to expire on March 31, 2000. Exercise of option is subject to the
    Company achieving certain specified annual financial performance goals.
    
 
     1996 Incentive Stock Option Plan. Effective as of February 28, 1996, the
Company adopted the 1996 Incentive Stock Option Plan (the "1996 Stock Plan"),
and granted options under the plan to acquire a total of 204,000 shares of
Common Stock to Terry K. Spencer, Garry D. Smith and Scott C. Longmore. The 1996
Stock Plan is intended to comply with Section 422 of the Internal Revenue Code
of 1986, as amended. Each incentive stock option ("ISO") granted entitles the
optionee to purchase up to 68,000 shares of Common Stock at an exercise price of
$0.26 per share, which the Board of Directors determined to represent the fair
market value of the Common Stock on the grant date. The exercise of each ISO is
conditioned upon the Company achieving certain specified financial performance
goals for each of calendar years 1997, 1998 and 1999, and the optionee may not
in any event exercise ISOs to acquire Common Stock having a fair market value in
excess of $150,000 for any one calendar year. The ISOs shall remain in effect
for the term of the Optionee's employment agreement with the Company. No more
ISOs may be issued under the 1996 Stock Plan.
 
     1997 Stock Plan. The purpose of the Continental Natural Gas, Inc. 1997
Stock Plan (the "1997 Stock Plan") is to promote the overall financial
objectives of the Company and its shareholders by motivating those persons
selected to participate in the 1997 Stock Plan to achieve long-term growth in
shareholder equity in the Company and by retaining the association of those
individuals who are instrumental in achieving this growth. Executive officers,
key employees and non-employee directors, as well as such other employees or
consultants as the Board of Directors selects, are eligible recipients of awards
under the 1997 Stock Plan. The maximum number of shares authorized to be issued
under the 1997 Stock Plan is 600,000 shares of Common Stock. No grants or awards
have been made under the 1997 Stock Plan.
 
     The 1997 Stock Plan is administered by the Board of Directors of the
Company. The Board of Directors is authorized to determine plan participants,
the types and amounts of awards to be granted and the terms, conditions and
provisions of awards, prescribe forms of award agreements, interpret the 1997
Stock Plan, establish, amend and rescind rules and regulations relating to the
1997 Stock Plan and make all other determinations which may be necessary or
advisable for the administration of the 1997 Stock Plan. The Board of Directors
has not made a determination as to the number of employees currently eligible
for consideration as participants in the 1997 Stock Plan.
 
     The 1997 Stock Plan permits the granting of any or all of the following
types of awards: (a) stock options, (b) stock appreciation rights ("SARs"), and
(c) restricted stock. Generally, awards under the 1997 Stock Plan are granted
for no consideration other than prior and future services. Awards granted under
the 1997
 
                                       42
<PAGE>   45
 
Stock Plan may, in the discretion of the Board, be granted alone or in addition
to, in tandem with or in substitution for any other award under the 1997 Stock
Plan or other plan of the Company. Such grants could include grants of options
after a decline in the market price of the Common Stock in substitution for
previously granted options having a higher exercise price.
 
     Stock options granted pursuant to the 1997 Stock Plan may, at the
discretion of the Board, be either ISOs within the meaning of Section 422 of the
Code, or non-qualified stock options. The exercise price of an ISO may not be
less than the fair market value of the Common Stock on the date of grant (or
110% of such fair market value in the case of ISOs granted to employees who
possess more than 10% of the combined voting power of all classes of stock of
the Company). In the case of non-qualified stock options, the exercise price
shall be as determined by the Board in its sole discretion, but in no event
shall be less than 50% of the fair market value of the Common Stock on the date
of grant. Options granted pursuant to the 1997 Stock Plan are exercisable in
whole or in part at such time or times as may be determined by the Board, except
that ISOs may not be exercised after the expiration of 10 years from the date
granted (or 5 years in the case of ISOs granted to employees who possess more
than 10% of the combined voting power of all classes of stock of the Company).
Generally, options may be exercised by the payment of cash, promissory notes,
stock or a combination thereof.
 
     Any SARs granted under the 1997 Stock Plan will give the holder the right
to receive cash or stock in an amount equal to the difference between the fair
market value of a share of Common Stock on the date of exercise and the exercise
price of the options issued in conjunction with the SARs or such other amount as
the Board has established with respect to SARs issued on a stand-alone basis.
Methods of exercise and settlement and other terms of SARs are determined by the
Board.
 
     The Board may award restricted stock, generally consisting of shares which
may not be disposed of by participants until certain restrictions established by
the Board lapse. Such restrictions may lapse in whole or in installments as the
Board determines. A participant receiving restricted stock will have all of the
rights of a shareholder of the Company, including the right to vote the shares
and the right to receive any dividends, unless the Board otherwise determines,
but shall not be permitted to sell, assign, or otherwise transfer the stock
during the restriction period established by the Board. Upon termination of
employment during the restriction period for any reason other than death or
disability, restricted stock will be forfeited, subject to such exceptions, if
any, as are authorized by the Board.
 
     In the event of any change affecting the shares of Common Stock by reason
of any stock dividend or split, recapitalization, merger, consolidation,
spin-off, combination or exchange of shares, or other corporate change or any
distributions to shareholders, the Board may make such substitution or
adjustment in the aggregate number or kind of shares which may be distributed
under the 1997 Stock Plan and in the number, kind and exercise, grant or
purchase price of shares subject to the outstanding awards granted under the
1997 Stock Plan, or make provisions for a cash payment relating to any award, as
it deems to be appropriate in order to maintain the purpose of the original
grant.
 
     The Board of Directors may amend, alter, suspend, discontinue or terminate
the 1997 Stock Plan without the consent of shareholders or participants, except
that shareholder approval of such action will be sought if such approval is
required by any federal or state law or regulation or by any agreement, or if
the Board of Directors in its discretion determines that obtaining such
shareholder approval is advisable. Unless earlier terminated by the Board of
Directors, the 1997 Stock Plan will terminate when no shares remain reserved and
available for issuance, and the Company has no further obligation with respect
to any award granted under the 1997 Stock Plan.
 
     In the event of a change of control of the Company, as defined in the 1997
Stock Plan, all outstanding awards under the 1997 Stock Plan, regardless of any
limitations or restrictions, become fully exercisable and freed of all
restrictions.
 
     Director Compensation. Directors receive no compensation from the Company
for serving on the Board of Directors but are eligible to receive grants under
the 1997 Stock Plan and will be reimbursed for out-of-pocket expenses incurred
while attending board and committee meetings.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
     As permitted by the provisions of the Oklahoma General Corporation Act (the
"Oklahoma Corporate Act"), the Certificate of Incorporation of the Company
eliminates in certain circumstances the monetary liability of directors of the
Company for a breach of their fiduciary duty as directors. These provisions do
not eliminate the liability of a director for (i) a breach of the director's
duty of loyalty to the Company or its shareholders, (ii) acts or omissions by a
director not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) liability arising under Section 1053 of the Oklahoma
Corporate Act (relating to the declaration of dividends and purchase or
redemption of shares in violation of the Oklahoma Corporate Act) or (iv) any
transaction from which the director derived an improper personal benefit. In
addition, these provisions do not eliminate the liability of a director for
violations of Federal securities laws, nor do they limit the rights of the
Company or its shareholders, in appropriate circumstances, to seek equitable
remedies such as injunctive or other forms of non-monetary relief. Such remedies
may not be effective in all cases.
 
     The Certificate of Incorporation and the Bylaws of the Company provide that
CNG shall indemnify all directors and officers of CNG to the full extent
permitted by the Oklahoma Corporate Act. Under such provisions, any director or
officer who in his capacity as such is made or threatened to be made, a party to
any suit or proceeding, may be indemnified by the Company if the Board of
Directors determines such director or officer acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interest of
CNG. The Certificate of Incorporation, Bylaws and the Oklahoma Corporate Act
further provide that such indemnification is not exclusive of any other rights
to which such individuals may be entitled under the Certificate of
Incorporation, the Bylaws, any agreement, vote of shareholders or disinterested
directors or otherwise.
 
     At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent of the Company where indemnification would
be required or permitted. The Company is not aware of any overtly threatened
litigation or proceeding that might result in a claim for indemnification.

                              CERTAIN TRANSACTIONS
 
GENERAL
 
     Gary C. Adams, the Chairman of the Board, President and Chief Executive
Officer of the Company, is the chief executive officer of Cottonwood
Partnership. Cottonwood Partnership is owned by certain trusts, the
beneficiaries of which are members of the immediate family of Mr. Adams (the
"Family Trusts"). Cottonwood Partnership owns approximately 98% of the
outstanding common stock of Adams Affiliates and all of the outstanding common
stock of Bird Creek Resources, Inc. ("Bird Creek"). Mr. Adams is a director and
the chairman of Adams Affiliates and a director of Bird Creek. The Family Trusts
are also partners in Mountain Meadows Partnership, a general partnership.
 
     Adams Affiliates owns, directly or indirectly, all of the outstanding
equity interests of Continental Natural Gas Marketing, L.L.C. ("CNGM"), Gary
Adams Ranch, Inc. ("G.A. Ranch"), CPA Ventures, Inc. ("CPA Ventures") and CPA
Aviation, Inc. ("CPA Aviation"). Mr. Adams is a director of G.A. Ranch, CPA
Ventures and CPA Aviation. Continental Gas Marketing, Inc. ("CGM") was a
subsidiary of Cottonwood Partnership until it was merged into Adams Affiliates
in 1997.
 
     The Company believes that the transactions described below were made on
terms at least as fair to the Company as could have been obtained from
unaffiliated third parties except that sales of natural gas by the Company to
CNGM in 1996 were at cost and below market. The Company believes that its sales
to CNGM in 1997 and thereafter will be fair to the Company.
 
1996 TRANSACTIONS AMONG RELATED ENTITIES
 
     The Beaver Plant was initially acquired by the Company and certain of its
affiliates. On January 1, 1996, the Company acquired the remaining 20% interest
in the Beaver Plant from Cottonwood Partnership, G.A. Ranch and CGM in exchange
for a total of 200 shares of Convertible Preferred Stock, and cancellation of an
account receivable from such affiliates in the amount of approximately $1.5
million. The terms of such exchange were not negotiated in an arms length
transaction. On December 1, 1996, the Company redeemed 51 shares of the
Convertible Preferred Stock for the liquidation value of $40,000 per share.
Prior to completion of the Offering, the remaining 149 shares of Convertible
Preferred Stock will be converted into 586,847 shares of Common Stock.
 
   
     The Company sold approximately $12 million of natural gas to CNGM in 1996.
The natural gas was sold at cost to CNGM, which resold such volumes under
long-term sales contracts. At December 31, 1996 and July 15, 1997, CNGM owed the
Company approximately $5 million and $3.1 million, respectively, for such
purchases. For 1997 and thereafter, the Company will sell sufficient natural gas
to CNGM to satisfy the requirements of its existing sales agreements at a price
equal to the Company's cost plus $0.02 per Mcf.
    
 
     In 1996, the Company purchased approximately $316,000 of natural gas
located in New Mexico and Oklahoma from Bird Creek under a month-to-month
contract. The Company's purchases from Bird Creek are made at a market index
price less gathering fees.
 
     In 1996, the Company provided office space and general administrative
services to Bird Creek and billed it for rentals and fees in the aggregate
amount of $258,652. Additionally, the Company in 1996, was charged $14,766 by
Bird Creek for general and administrative expenses incurred on its behalf. In
1996, Adams Affiliates charged the Company $210,000 for management services.
Adams Affiliates and the Company are parties to a Consulting Agreement dated as
of April 1, 1997, under which Adams Affiliates provides consulting services to
the Company. See "Management -- Executive Compensation."
 
     Bird Creek and Adams Affiliates are parties to Administrative Services
Agreements with the Company dated as of April 1, 1997, under which the Company
provides office space, accounting, clerical and other administrative services to
Bird Creek and Adams Affiliates in return for reimbursement to the Company of
the allocable cost to the Company of providing such services. These
Administrative Services Agreements expire on March 31, 1998, subject to
automatic renewal on a month-to-month basis thereafter until terminated by any
of the contracting parties. Bird Creek provides certain accounting, clerical and
administrative services to
 
                                       46
<PAGE>   49
 
the Company (primarily accounting services) under the terms of an Administrative
Services Agreement dated as of April 1, 1997. The Company reimburses Bird Creek
for the allocable cost to Bird Creek of providing such services. This
Administrative Services Agreement expires on March 31, 1998, subject to
automatic renewal on a month-to-month basis thereafter until terminated by one
of the parties.
 
     In 1996, the Company sold its oil and gas producing properties to Adams
Affiliates for $308,000, which approximated book value.
 
   
     In 1996, the Company paid CPA Aviation and CPA Ventures a total of $175,600
for aviation services. Approximately $56,000 of the amount paid in 1996 was
related to services rendered in 1995. The Company and CPA Aviation are parties
to a charter services agreement dated as of April 1, 1997, under which CPA
Aviation agrees to provide aviation services to the Company on an "as needed"
basis (the "Charter Services Agreement"). The Company is required to pay CPA
Aviation for such services at the rates of $100 per hour for usage of a Cessna
Model Turbo 210 aircraft and $1,000 per hour for usage of a Learjet Model 24F
aircraft plus reimbursement of any taxes, fees, customs duties or other charges
which CPA Aviation may be required to pay by reason of the Company's usage. The
Charter Services Agreement expires on March 31, 1998, subject to automatic
renewal on a month-to-month basis thereafter until terminated by one of the
parties.
    
 
   
     As of December 31, 1996 and July 15, 1997, Mountain Meadows Partnership was
indebted to the Company in the amount of approximately $800,000. Various other
affiliates of Cottonwood Partnership were indebted to the Company in the
aggregate amount of approximately $212,000 as of July 15, 1997.
    
 
OTHER RELATIONSHIPS
 
     Oppenheimer & Co., Inc. is an Underwriter and a representative of the
Underwriters in the Offering. See "Underwriting." Mr. William H. Bauch is an
officer of Oppenheimer & Co., Inc. and is expected to become a director of the
Company following the Offering. The law firm of Hall, Estill, has advised the
Company on certain legal matters related to the Offering. Mr. William W.
Pritchard is Of Counsel to Hall, Estill and is expected to become a director of
the Company following the Offering.
 
BOARD POLICY ON AFFILIATED TRANSACTIONS
 
     The Board of Directors has adopted a policy requiring that any transactions
to be entered into between the Company and an affiliate of the Company after
completion of the Offering be reviewed by CNG's independent directors.

<PAGE>   50
 
                          DESCRIPTION OF CAPITAL STOCK
 
   
     Upon the closing of the Offering, the authorized capital stock of the
Company will consist of 60,000,000 shares of Common Stock, $0.01 par value and
5,000,000 shares of Preferred Stock, $0.01 par value. The Convertible Preferred
Stock will be converted into 586,847 shares of Common Stock prior to completion
of the Offering. Accordingly, the terms of the Convertible Preferred Stock are
not discussed herein.
    
 
COMMON STOCK
 
     Each holder of Common Stock is entitled to one vote for each share on all
matters on which shareholders generally are entitled to vote, including
elections of directors, and, except as otherwise required by law or by the terms
of any series of Preferred Stock of the Company, the holders of Common Stock
exclusively possess all voting power. The Certificate of Incorporation of the
Company (the "Certificate") does not provide for cumulative voting for the
election of directors; therefore, the holders of a majority of the voting power
of the total number of outstanding shares of Common Stock are able to elect the
entire Board of Directors of the Company.
 
     Subject to any preferential rights of any outstanding series of Preferred
Stock of the Company designated from time to time by the Board of Directors, the
holders of Common Stock are entitled to such dividends as may be declared from
time to time by the Board of Directors from funds legally available therefor
and, upon liquidation, dissolution or winding up, will be entitled to receive
pro rata all assets of the Company available for distribution to such holders.
No holder of Common Stock has any preemptive right to subscribe to any kind or
class of securities of the Company.
 
PREFERRED STOCK
 
   
     The Board of Directors is empowered without shareholder approval to issue
up to 5,000,000 shares of Preferred Stock of the Company, from time to time, in
series and with respect to each series to determine (i) the number of shares
constituting such series, (ii) the dividend rate on the shares of each series,
whether such dividends shall be cumulative and the relation of such dividends
payable on any other class or series of stock, (iii) whether the shares of each
series shall be redeemable and the terms thereof, (iv) whether the shares shall
be convertible into Common Stock and the terms thereof, (v) the amount per share
payable on each series, or other rights of holders of such shares on liquidation
or dissolution of the Company, (vi) the voting rights, if any, of shares of each
series and (vii) generally, any other rights and privileges consistent with the
Certificate for each series and any qualifications, limitations or restrictions.
No shares of Preferred Stock are presently outstanding, and the Company has no
present intention to issue Preferred Stock.
    
 
ANTI-TAKEOVER PROVISIONS
 
     Certain provisions of the Certificate and the Company's Bylaws may have the
effect of preventing, discouraging or delaying a change in the control of the
Company and may maintain the incumbency of the Board of Directors and
management. The Company's Bylaws limit the ability of shareholders of the
Company to raise matters at a meeting of shareholders without giving advance
notice. In addition, the Certificate and the Bylaws prohibit shareholders from
removing the Company's directors without cause. The Certificate of Incorporation
and Bylaws provide for a classified Board of Directors, which means that only
one-third of the members of the Board of Directors will be up for election in
any given year. The ability of the Board of Directors to issue Preferred Stock
as described above may also make it more difficult for, and may discourage,
other persons or companies from making a tender offer for, or attempting to
acquire substantial amounts of, the Company's Common Stock.
 
     The Company is subject to the provisions of the Oklahoma Takeover
Disclosure Act of 1985 (the "Disclosure Act") regulating corporate takeovers.
The Disclosure Act requires certain notices to be given prior to making a
takeover offer. Such notices include filing a registration statement with the
Securities Administrator of Oklahoma and delivering a copy of such notice to the
Company. The Disclosure Act applies to offers to takeover an issuer of publicly
traded securities of which at least 20% are held by Oklahoma residents. A
"takeover" offer includes offers in which the offerer discloses its intention
that, as a result of the
 
                                       48
<PAGE>   51
 
offer: (i) the offeror will own 10% or more of any class of equity securities or
(ii) ownership of any class of equity securities will be increased by 5% or
more.
 
     The Company is subject to the provisions of Section 1090.3 of the Oklahoma
Corporate Act. That section provides, with certain exceptions, that an Oklahoma
corporation may not engage in any of a broad range of business combinations with
a person or an affiliate or associate of such person who is an "Interested
Shareholder" for a period of three years from the date that such person became
an Interested Shareholder unless: (a) the transaction, or business combination,
resulting in a person's becoming an Interested Shareholder is approved by the
board of directors of the corporation before the person becomes an Interested
Shareholder, (b) upon consummation of the transaction which resulted in the
person becoming an Interested Shareholder, the Interested Shareholder owned 85%
or more of the voting stock of the corporation outstanding at the time the
transaction commenced (excluding shares owned by persons who are both officers
and directors of the corporation and shares held by certain employee stock
ownership plans) or (c) on or after the date the person became an Interested
Shareholder, the business combination is approved by the corporation's board of
directors and by the holders of at least 66 2/3% of the corporation's
outstanding voting stock at an annual or special meeting, excluding shares owned
by the Interested Shareholder. An "Interested Shareholder" is defined as any
person that is (a) the owner of 15% or more of the outstanding voting stock of
the corporation or (b) an affiliate or associate of the corporation and was the
owner of 15% or more of the outstanding voting stock of the corporation at any
time within the three-year period immediately prior to the date on which it is
sought to be determined whether such person is an Interested Shareholder.
 
     The Oklahoma Shares Control Act ("OSCA") (Section 1145 et seq. of the
Oklahoma Corporate Act) prohibits the voting of "control shares" without the
approval of a majority of shares held by non-interested shareholders. Under the
OSCA, "control shares" are shares acquired by a person which causes his
percentage ownership to exceed certain statutorily prescribed ranges of
ownership beginning at 20%. The OSCA was ruled unconstitutional shortly after
its adoption in 1987; however, it is believed that certain amendments to the
OSCA in 1990 and 1991 may have cured its constitutional infirmities.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Prior to the Offering, there has not been any public market for the Common
Stock. Sale of a substantial number of shares of Common Stock into the public
market following the Offering could adversely affect prevailing market prices
for the Common Stock.
 
   
     Following the Offering, the Company will have outstanding an aggregate of
6,000,000 shares of Common Stock, assuming no exercise of the underwriters'
over-allotment option. In addition to the 2,100,000 shares of Common Stock
offered hereby, as of the effective date of the Offering, there will be
3,900,000 shares of Common Stock outstanding, all of which are restricted
securities (the "Restricted Shares") under the Securities Act. All shareholders
of the Company have agreed they will not sell 3,900,000 shares of Common Stock
held by them without the prior consent of the representatives of the
Underwriters for a period of 180 days from the date of this Prospectus (the
"180-day Lockup Period"). Following the 180-day Lockup Period, up to 3,900,000
Restricted Shares will become eligible for sale in the public market pursuant to
Rule 144 subject to the volume and other restrictions pursuant to such Rule. The
Underwriters may, in their sole discretion and at any time prior to the
expiration of the 180-day Lockup Period without notice, release all or any
portion of the securities subject to lock-up agreements.
    
 
     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated), who has beneficially owned shares for at least one
year (including the holding period of any prior owner except an affiliate) is
entitled to sell in "broker's transactions" or to market makers, within any
three-month period, a number of shares that does not exceed the greater of (i)
1% of the then outstanding shares of Common Stock or (ii) generally, the average
weekly trading volume in the Common Stock during the four calendar weeks
preceding the sale. Sales under Rule 144 are also subject to the filing of a
Form 144 with respect to such sale and certain other limitations and
restrictions. Under Rule 144(k), a person who is not deemed to have been an
affiliate of the Company at any time during the 90 days preceding a sale, and
who has beneficially owned the shares proposed to be sold for at least two
years, would be entitled to sell such shares without having to comply with the
manner of sale, volume limitation or notice filing provisions described above.
 
     The Company is unable to estimate the number of shares that will be sold
under Rule 144, as this will depend on the market price for the Common Stock of
the Company, the personal circumstances of the sellers and other factors. Prior
to the Offering, there has been no public market for the Common Stock, and there
can be no assurance that a significant public market for the Common Stock will
develop or be sustained after the Offering. Any future sale of substantial
amounts of the Common Stock in the open market may adversely affect the market
price of the Common Stock offered hereby.
 
     The Company intends to file a registration statement on Form S-8 under the
Securities Act to register up to 600,000 shares of Common Stock reserved for
issuance under the 1997 Stock Plan, thus permitting the resale of such shares by
nonaffiliates in the public market without restriction under the Securities Act,
subject to vesting restrictions with the Company. The 204,000 shares subject to
purchase under the Company's 1996 Stock Option Plan are Restricted Shares.

</TABLE>
 
     The Underwriting Agreement provides that the obligations of the
Underwriters thereunder are subject to approval of certain legal matters
(including, among other things, the legality of the issuance of shares of Common
Stock in the Offering) by counsel and to various other conditions. The nature of
the Underwriters' obligations is such that they are committed to purchase all of
the above shares of Common Stock if any are purchased.
 
     The Underwriters propose to offer the shares of Common Stock directly to
the public at the Offering price set forth on the cover page of this Prospectus
and at such price less a concession not in excess of $          per share of
Common Stock to certain securities dealers who are members of the National
Association of Securities Dealers, Inc. The Underwriters may allow and such
dealers may reallow concessions not in excess of $          per share to certain
other securities dealers. After the initial public offering, the offering price
and other selling terms may be changed by the Representatives.
 
     The Underwriters have been granted a 30-day over-allotment option to
purchase from the Company up to an aggregate of 315,000 additional shares of
Common Stock at the public offering price less the underwriting discount and
commissions. If the Underwriters exercise such over-allotment option, the
Underwriters have severally agreed, subject to certain conditions, to purchase
approximately the same percentage thereof as the number of shares of Common
Stock to be purchased by it as shown in the above table bears to the number of
shares of Common Stock offered hereby and the Company will be obligated,
pursuant to the over-allotment option, to sell such shares to the Underwriters.
The Underwriters may exercise such option only to cover over-allotments made in
connection with the sale of Common Stock offered hereby.
 
     The Representatives, on behalf of the Underwriters, may engage in
over-allotment, stabilizing transactions, syndicate covering transactions and
penalty bids in accordance with Regulation M under the Exchange Act.
Over-allotment involves syndicate sales in excess of the offering size, which
creates a syndicate short position. Stabilizing transactions permit bids to
purchase the underlying security so long as the stabilizing bids do not exceed a
specified maximum. Syndicate covering transactions involve purchases of the
Common Stock in the open market after the distribution has been completed in
order to cover syndicate short positions. Penalty bids permit the
Representatives to reclaim a selling concession from a syndicate member when the
Common Stock originally sold by such syndicate member is purchased in a
syndicate covering transaction to cover syndicate short positions. Such
stabilizing transactions, syndicate covering transactions, penalty bids and
passive market making may cause the price of the Common Stock to be higher than
it would otherwise be in
 
                                       51
<PAGE>   54
 
the absence of such transactions. These transactions may be effected on the
Nasdaq National Market or otherwise and, if commenced, may be discontinued at
any time.
 
     The Representatives have advised the Company that they do not intend to
confirm sales to any accounts over which they exercise discretionary authority.
 
   
     The Company has agreed to pay the Representatives a financial advisory fee
equal to 3/4 of 1% of the total proceeds of the Offering. In addition, the
Company has agreed to indemnify the Underwriters against certain liabilities,
losses and expenses, including liabilities under the Securities Act or to
contribute to payments that the Underwriters may be required to make in respect
thereof.
    
 
   
     All shareholders of the Company have agreed that for a period of 180 days
after the date of this Prospectus they will not sell, contract to sell or
otherwise dispose of, directly or indirectly, shares of Common Stock without the
prior written consent of the Representatives.
    
 
                                 LEGAL MATTERS
 
   
     The validity of the issuance of shares of Common Stock offered hereby will
be passed upon for the Company by Albright & Rusher, a Professional Corporation,
Tulsa, Oklahoma. Certain legal matters in connection with the Offering will be
passed upon for the Company by Hall, Estill, Hardwick, Gable, Golden & Nelson,
P.C., Tulsa, Oklahoma. Certain legal matters in connection with the Offering
will be passed upon for the Underwriters by Jackson Walker L.L.P., Dallas,
Texas.
    
 
                         INDEPENDENT PUBLIC ACCOUNTANTS
 
   
     The consolidated balance sheets as of December 31, 1995 and 1996 and the
consolidated statements of operations, shareholders' equity and cash flows for
each of the three years in the period ended December 31, 1996 included in this
prospectus, have been included herein in reliance on the report of Coopers &
Lybrand L.L.P., independent accountants, given on the authority of that firm as
experts in accounting and auditing. With respect to the unaudited interim
financial information for the periods ended March 31, 1996 and 1997, included in
this Prospectus, the independent accountants have reported that they have
applied limited procedures in accordance with professional standards for a
review of such information. However, their separate report included in the
Prospectus states that they did not audit and they do not express an opinion on
that interim financial information. Accordingly, the degree of reliance on their
report on such information should be restricted in light of the limited nature
of the review procedures applied. The accountants are not subject to the
liability provisions of Section 11 of the Securities Act for their report on the
unaudited interim financial information because that report is not a "report" or
a "part" of the registration statement prepared or certified by the accountants
within the meaning of Sections 7 and 11 of the Securities Act.

net income as a measure of the Company's operating results or to cash flows from

natural gas without curtailment or reduction up to the quantity which the
pipeline has committed to transport under the contract with its customer. Under
firm transportation, the pipeline reserves sufficient capacity on its pipelines
to satisfy the transportation requirements of all firm transportation customers
without curtailment (except for curtailment which may result due to acts of God
or similar occurrences).
 
     "Fractionation" is the process by which the NGL stream is subjected to
controlled temperatures, causing the NGLs to separate, or fractionate, into the
separate NGL products of ethane, propane, butane, isobutane and natural
gasoline.
 
     "Fuel and shrinkage" is the heating value of the natural gas extracted in
the form of NGLs or consumed as fuel during processing.
 
     "Interruptible transportation" means the obligation of a pipeline to
transport natural gas on a "first come -- first serve" basis after the pipeline
has satisfied all of its firm transportation obligations.
 
     "Mcf" means thousand cubic feet of natural gas.
 
     "Mgal/d" means thousand gallons per day.
 
     "MMcf" means million cubic feet of natural gas.
 
     "MMcf/d" or "MMcf per day" means million cubic feet per day.

located in Beaver County, Oklahoma which is not directly connected to the Beaver
Gathering System.

     "Reserves" mean proven/producing natural gas reserves from wells whose
production is processed and/or gathered at the Company's plants and/or pipeline
systems.

the Company from subsidiaries of Enron Corporation.

natural gas stream that would interfere with pipeline transportation or
marketing of the natural gas to consumers.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors
Continental Natural Gas, Inc. and Subsidiaries
 
     We have audited the accompanying consolidated balance sheets of Continental
Natural Gas, Inc. and Subsidiaries as of December 31, 1995 and 1996, and the
related consolidated statements of operations, shareholders' equity, and cash
flows for the years ended December 31, 1994, 1995 and 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Continental
Natural Gas, Inc. and Subsidiaries as of December 31, 1995 and 1996, and the
consolidated results of their operations and their cash flows for the years
ended December 31, 1994, 1995 and 1996 in conformity with generally accepted
accounting principles.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
     We have reviewed the accompanying consolidated balance sheet of Continental
Natural Gas, Inc. and Subsidiaries as of March 31, 1997, and the related
consolidated statements of operations and cash flows for the three-month periods
ended March 31, 1996 and 1997 and the consolidated statement of shareholders'
equity for the three-month period ended March 31, 1997. These financial
statements are the responsibility of the Company's management.
 
     We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical procedures to
financial data and making inquires of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit conducted in
accordance with generally accepted auditing standards, the objective of which is
the expression of an opinion regarding the financial statements taken as a
whole. Accordingly, we do not express such an opinion.
 
     Based on our review, we are not aware of any material modifications that
should be made to the accompanying financial statements for them to be in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     NATURE OF OPERATIONS -- Continental Natural Gas, Inc. and Subsidiaries (the
"Company") is an Oklahoma corporation involved principally in natural gas
gathering, processing and marketing with operations principally in the central
United States. The consolidated financial statements include the accounts of the
Company, its wholly-owned subsidiaries and its investments in majority-owned
partnerships.
 
     CASH EQUIVALENTS -- The Company considers all highly liquid investments
with maturities of three months or less at date of purchase to be cash
equivalents.
 
     INVENTORY -- Gas inventory is stated at the lower of market or average
cost.
 
     PROPERTY AND EQUIPMENT -- The Company's property and equipment is carried
at cost and depreciated on the straight-line basis over their estimated useful
lives ranging from 3 to 20 years. Gain or loss on disposal of such property and
equipment is reflected in operations. Maintenance and repairs are charged to
expense as incurred.
 
     The carrying value of property and equipment is reviewed for possible
impairment whenever events or changes in circumstances indicate that the
carrying value may not be recoverable. Assets determined to be impaired based on
estimated future net cash flows are reduced to estimated fair value. No such
reduction in the carrying value of assets has been reflected in the accompanying
financial statements.
 
     OIL AND GAS PROPERTIES -- Costs incurred in the acquisition, exploration
and development of oil and gas properties owned in prior years were capitalized
utilizing the full cost method and depleted using the units-of-production method
based on proved reserves.
 
     DEBT ISSUANCE COSTS -- Costs associated with obtaining financing are
capitalized and amortized using the straight-line method over the term of the
agreement.
 
     REVENUE RECOGNITION -- Revenue is recognized when product is delivered or
when services are rendered.
 
     INCOME TAXES -- The Company accounts for income taxes utilizing Statement
of Financial Accounting Standards No. 109, "Accounting for Income Taxes," which
requires recognition of deferred tax liabilities and assets for the expected
future tax consequences of events that have been included in the financial
statements or tax returns. Under this method, deferred tax liabilities and
assets are determined based on the difference between the financial statement
and tax bases of assets and liabilities using enacted tax rates in effect for
the year in which the differences are expected to reverse.
 
     EARNINGS PER SHARE -- Earnings per share is based on the weighted average
number of shares outstanding. Primary earnings per share assumes that
outstanding dilutive stock options and warrants are exercised and the proceeds
used to purchase common shares. Fully diluted earnings per share gives effect to
the conversion of convertible preferred stock and the exercise of dilutive stock
options.
 
     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 those estimates.
 
     RECLASSIFICATIONS -- Certain 1994 and 1995 amounts have been reclassified
to conform to the current year presentation.

     At December 31, 1995 and 1996, notes receivable from affiliates related to
a sale of a gathering system in prior years were $17,801. This note bears
interest at 8% and is collateralized by the gathering system. Also, at December
31, 1995, the Company had notes receivable from affiliates totaling $1,320,352,
related to these parties' participation with the Company in the ownership of
certain gathering systems and processing plants. Accrued interest on these notes
totaling $153,206 at December 31, 1995, is included in accounts receivable-
affiliate. This receivable was collected in 1996 as part of the Company's
acquisition of the affiliate's interest in the plant.
 
3. INVESTMENTS
 
     The Company, through two limited partnerships of which it is the general
partner, owns a 6.88% interest in a partnership which owns and operates a
natural gas gathering system in Texas. The Company's ownership interest is
accounted for using the equity method. Accordingly, during 1994, 1995 and 1996,
the Company has recognized losses of $51,486, $82,769 and $136,196,
respectively, from the investment.

     In March and May of 1996, the Company purchased gas gathering systems for
combined consideration of $20.2 million.
 
     In December 1994, the Company sold a gathering system and processing plant
and recognized a $5.2 million gain on the sale, of which $1.3 million was
attributable to the minority ownership interests of related parties. The Company
utilized a portion of the proceeds from this sale to acquire a gas processing
plant and related assets in February 1995 for $3.5 million. The acquisition also
provides for contingent consideration

of up to $1.5 million ($500,000 per year for three years) plus associated
interest on any such amounts, based on the delivery of a certain supplier's gas
to the plant for processing. As the provisions of the agreement related to this
consideration were met in 1995, at December 31, 1995, the Company accrued
$500,000 plus interest related to this commitment. In 1996, the Company did not
receive gas for processing at this plant from the supplier, and accordingly,
does not believe that any additional consideration will be payable.
 
5. LONG-TERM DEBT
 
     Long-term debt at December 31, 1995 and 1996 consists of the following:

</TABLE>
 
     In December 1996, the Company obtained a new credit facility including the
term loan above and a revolving credit facility of $25 million, of which up to
$18 million may be utilized to support letters of credit. Letters of credit
totalling $6,885,990 were outstanding related to this credit facility at
December 31, 1996. At December 31, 1996, no amount was outstanding on the
revolving credit facility which has a maturity of December 31, 1998 and also
accrues interest at either the bank's base rate plus .5% or LIBOR plus 2.25%.
The new agreement also provides borrowing availability of up to $4,800,000 for
approved capital projects. Associated with obtaining the new credit facility,
the Company retired its prior long-term debt and expensed the remaining
unamortized debt issuance costs of $689,062, which expense (net of income taxes
of $261,842) is classified as an extraordinary item in the statement of
operations.
 
     The debt under the agreements is collateralized by inventory, accounts
receivable, property and equipment and other assets. The agreement includes
various restrictive covenants including the maintenance of specified levels of
working capital and net worth, limitations on the incurrence of additional
indebtedness and limitations on dividends to shareholders.
 
     The Company's prior debt agreement included the issuance of stock purchase
warrants which entitled the holder of the warrants to purchase 127,840 shares of
common stock of the Company. During 1995, all such warrants were repurchased by
the Company for a total of $315,000.
 
     At December 31, 1996, the aggregate amount of long-term debt is payable as
follows: $867,000 in 1997; $4,765,000 in 1998; $4,765,000 in 1999; $4,765,000 in
2000 and $18,650,500 in 2001. Beginning in 1998, certain additional principal
amounts may be due based on the Company's levels of operating cash flows as
defined by the agreement.

7. CONTRACT ADVANCES
 
     In December, 1996, the Company received contract advances totalling
approximately $22.8 million related to commitments to sell natural gas and
natural gas liquids. The advances do not bear interest and are payable in
product to be delivered over approximately nine months beginning in January
1997.
 
     In June of 1994, the Company received a contract advance of approximately
$2.7 million related to a commitment to sell natural gas liquids. This advance
does not bear interest, is payable in cash or in product, and has a final
repayment date of June, 1997. The Company may terminate the contract and repay
this advance at its option with 30 days notice. During 1995, the Company elected
to reduce the contract advance by delivery of ethane volumes, reducing the
contract advance by approximately $756,000.

     At December 31, 1996, the Company had net operating loss carryforwards
(NOLs) totaling approximately $17.5 million for regular tax purposes and $18.0
million for alternative minimum tax purposes. If not utilized, these
carryforwards will expire from 1999 to 2003. Due to the lack of existing legal
precedent with respect to the tax rules governing the Company's NOLs, both the
availability of the Company's NOLs and its prior utilization of NOLs (totaling
approximately $37 million) may be challenged. Disallowance of the use of the
NOLs would result in taxes associated with prior utilization of the NOLs being
currently payable.
 
     Realization of the Company's deferred tax assets is dependent upon the
generation of sufficient taxable income prior to the expiration of the NOLs and,
for financial reporting purposes, the resolution of the matters noted above.
Although realization is not assured, management believes it is more likely than
not that the recorded net deferred tax asset will be realized. The amount of the
deferred tax asset considered realizable could be increased or decreased by a
material amount in the near-term pending resolution of these matters.
 
9. COMMITMENTS AND CONTINGENCIES
 
     The Company, in the ordinary course of business, enters into fixed price
sales contracts of natural gas. At December 31, 1995, the Company had fixed
price gas sales contracts for prices ranging between $1.43 and $2.30 for the
period January 1, 1996 and July 31, 1997. At December 31, 1996, the Company had
fixed price gas sales contracts for prices ranging between $1.83 and $2.46 for
the period January 1, 1997 to August 31, 1998.

                 CONTINENTAL NATURAL GAS, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     As of December 31, 1996, the Company has outstanding $27,519,090 of letters
of credit from commercial banks related to its purchases and sales of gas and
has pledged inventory, accounts receivable, property and equipment and other
assets as collateral.
 
     The Company occupies office space and maintains certain compressor
equipment under operating leases and incurred rent expense of $1,461,300,
$1,839,000 and $1,931,708 in 1994, 1995 and 1996, respectively. Future minimum
rental payments under the terms of the leases are $191,473 in 1997.
 
     The Company is currently a defendant in litigation which involves primarily
claims made by Colorado Interstate Gas ("CIG") that the Company and Continental
Hydrocarbons, Inc. ("CHI"), a former subsidiary of the Company, improperly
withheld proceeds from the sale of natural gas liquids processed at one of the
Company's plants, have (among other things) defamed CIG and are, as a result,
liable to CIG for unspecified actual and punitive damages. The companies from
which CHI purchased the plant have also been sued by CIG and have sought
indemnity from CHI and the Company for any liability they may have to CIG as
well as other amounts allegedly owed them. The Company and CHI have generally
denied the allegations against them in the case and have contended that they are
owed certain amounts for the processing of natural gas. Though impossible to
estimate with certainty, the Company believes that CIG is seeking actual damages
in excess of $3 million. Additionally, the Company is currently involved in
pending proceedings at the FERC in which certain parties allege that the primary
function of the Company's processing plants is interstate transportation and
thus that they are subject to FERC rate and certificate regulation. While the
Company believes that its business is not subject to regulation by the FERC, it
cannot predict the outcome of these proceedings. Various other lawsuits against
the Company have arisen in the ordinary course of the Company's business. In the
opinion of management, resolution of the CIG litigation, the FERC proceedings
and such other matters will not have a material adverse effect on results of
operations or financial position.
 
10. PROFIT SHARING AND THRIFT PLAN
 
     The Company currently participates with certain affiliates in a defined
contribution plan (the "Plan") covering substantially all employees. Under the
Plan provisions, the Company contributes 2% of each participant's annual salary,
plus up to an additional 3% to match voluntary contributions by employees.
Employees may make voluntary contributions of up to 10% of their annual
compensation. The Company makes contributions to the Plan each pay period. Total
expense for 1994, 1995 and 1996 was approximately $120,000, $106,000 and
$141,500, respectively.
 
11. SHAREHOLDERS' EQUITY
 
     Preferred stock of the Company is convertible at the option of the holders
into 586,847 shares of common stock of the Company. The preferred stock includes
a liquidation preference equal to $40,000 per share plus all unpaid dividends.
Dividends on the preferred stock are cumulative from the date of issuance at a
rate of 7 1/2% applied to the liquidation value. At December 31, 1996, unpaid
dividends totaling $587,250 had accumulated on the Preferred Stock.
 
     On January 1, 1996, the Company issued 200 shares of preferred stock in
exchange for the minority interest ownership in the Beaver gas processing plant.
As the minority interest ownership was held by affiliates of the Company with
common ownership, the assets and liabilities associated with the acquired
interest have been reflected at their historical amounts. Subsequently, the
Company redeemed 51 shares of the preferred stock in exchange for cancellation
of indebtedness owed the Company.
 
     As of December 31, 1994, stock options were outstanding on 68,000 shares of
common stock exercisable at $1.47 per share through December 31, 1997. During
1995, all such stock options were canceled. Also during 1995, the Company
granted certain employees phantom stock rights under which certain amounts would

and certain members of management were granted stock options for 204,000 shares
of common stock. These options become exercisable only if certain performance
criteria of the Company are met during the years of 1997 through 1999. The
options, if earned, are exercisable at $.26 per share and expire at March 31,
2000. The amount of the options exercisable may also be limited based on the
fair value of the Company's common stock at the date of exercise. The Company
applies APB 25 in accounting for such stock options. Under this standard,
compensation expense may be recognized associated with these options when
earned, based on the fair value of the Company's common stock at the dates they
are earned. Based on the provisions of Financial Accounting Standard No. 123,
"Accounting for Stock-Based Compensation," the grant date fair value of these
options is not material and, accordingly, disclosure of pro forma information as
required by this standard has not been presented.
    
 
   
     Also on February 28, 1996, the Company sold 461,997 shares of common stock
of the Company to certain members of Company management for $100,000, payable in
the form of notes receivable due in April of 1997 with interest at 8%. Based on
the fair value of the Company's common stock at this date, compensation expense
and a contribution of capital of $46,000 has been recognized in 1996.
    
 
12. FINANCIAL INSTRUMENTS
 
     DERIVATIVES -- The Company enters into futures contracts and options
related to its buying and selling of natural gas. Specifically, the Company
hedges its cost of future purchases of natural gas associated with its fixed
price sales commitments. At December 31, 1995, the Company had futures contracts
to purchase natural gas totaling approximately $1.8 million for the period from
January of 1996 to April of 1996. At December 31, 1996, the Company had futures
contracts to purchase natural gas totaling approximately $6.5 million for the
period from January of 1997 to April of 1998. Also, at December 31, 1995, the
Company had swap contracts on natural gas totaling approximately $1.3 million
for the period of January and February of 1996. At December 31, 1996, the
Company had swap contracts whereby the Company had fixed its price with respect
to future purchases of natural gas totaling approximately $7.2 million for the
period of January of 1997 to August of 1997. At December 31, 1995, the Company
had sold put options on approximately 500,000 mcf of natural gas at prices of
$2.00 to $2.25. At December 31, 1995 and 1996, the Company had deposits totaling
$458,873 and $962,553, respectively, related to these contracts which are
reflected as Accounts Receivable -- Other.
 
     Gains or losses on futures contracts, swaps and options designated as
hedges are reflected in the Consolidated Statement of Operations in the same
period as the associated sale of gas occurs. Gains or losses on futures
contracts, swaps and options not designated as hedges are recognized as
fluctuations occur in the value of the contracts. At December 31, 1996, all
futures and swap contracts relating to the purchase of natural gas were
designated as hedges. Gains on futures contracts totalling approximately $1.1
million at December 31, 1996 have been deferred. At December 31, 1996, the fair
value of the swap contracts was approximately $2 million, which amount has also
been deferred.
 
     At December 31, 1994 and 1995, no futures contracts or options were
designated as hedges. At December 31, 1994, losses of $1,027,519 on futures
contracts have been included in costs of purchased gas. At December 31, 1995,
gains of $278,020 related to open futures contracts have been recognized and
included in Marketing Fees and Other Revenues.
 
     Additionally, the Company periodically enters into futures contracts on
behalf of its gas purchasers, with gains or losses on such contracts paid or
billed to these customers. At December 31, 1995 and 1996, such contracts were
not material.
 
     FAIR VALUE -- Based on the interest rates currently available to the
Company for borrowings with similar terms and maturities, long-term debt and
capital leases at December 31, 1995 and 1996 approximate fair value.

     The estimated fair value of the contract advance liabilities at December
31, 1995 and 1996, assuming repayment under the scheduled terms of the
agreements, is approximately $1.7 and $24.3 million, respectively.
 
     The fair value of the Company's futures and swaps at December 31, 1995 was
approximately $.3 million and $1.2 million, respectively. The fair value of the
Company's futures positions and swaps at December 31, 1996 was approximately
$1.1 million and $2 million, respectively.
 
13. CONCENTRATIONS
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist primarily of trade receivables with a
variety of companies located in the central United States. Such credit risk is
considered by management to be limited due to the large number of customers
comprising the Company's customer base. The Company performs ongoing credit
evaluations of its customers and generally does not require collateral related
to its receivables. The Company's derivative activities also subject it to
credit risk. Such credit risk is considered by management to be limited based on
its assessment of the financial strength of the individual counterparties to its
derivative positions. Additionally, the Company had $5,039,000 and $32,197,000
of cash balances with banks at December 31, 1995 and 1996, respectively.
 
     In fiscal years 1995 and 1996, one customer accounted for approximately 23%
and 12% of consolidated revenues, respectively. At December 31, 1995 and 1996,
accounts receivable from this customer were $3,538,932 and $2,429,622,
respectively.
 
14. SUBSEQUENT EVENTS
 
   
     In February 1997, the Company began negotiations with certain underwriters
for a proposed public offering (the "Offering") of approximately $23 million of
common stock. In connection with the Offering, the Company intends to reduce the
par value of each share of common stock from $1.00 to $.01, increase the
authorized common stock to 60,000,000 shares and the authorized preferred stock
to 5,000,000 shares, and effect an approximate 136 to 1 common stock split. The
accompanying financial statements reflect these changes as if they had occurred
at December 31, 1993. The Company expects to use the net proceeds of the
Offering to retire a substantial portion of its outstanding long-term debt.
    
 
15. INTERIM FINANCIAL STATEMENTS (UNAUDITED)
 
     The interim consolidated financial statements presented herein are
unaudited, but reflect, in the opinion of management, all adjustments (which
include only normal recurring adjustments) necessary for fair presentation of
the results for such periods.
 
     The Company has reached a settlement with one of the Mocane Plant Sellers
which involves the Company's payment of approximately $1.2 million plus accrued
interest (on a portion of the settlement) to such Mocane Plant Seller (See Note
9). The Company had previously recorded an accrued liability for a portion of
the proceeds received from the processing of gas through the Mocane system and
accordingly no additional provision is required. It is expected that this
settlement will be concluded in the third quarter of 1997 at the same time as
the Company purchases the interest of Conoco and its affiliate in the Laverne
Plant.
 
     As a result of the utilization of the net operating loss carryforward for
financial reporting purposes in the fourth quarter of 1996, the income tax
provision for the first quarter of 1997 approximates the statutory rate for
federal and state income taxes.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     As permitted by the Oklahoma General Corporation Act (the "Oklahoma
Corporate Act"), the Company's Certificate of Incorporation eliminates the
personal liability of a director to the Company for monetary damages for breach
of fiduciary duty of care as a director. Liability is not eliminated for (i) any
breach of the director's duty of loyalty to the Company or its stockholders,
(ii) acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (iii) unlawful payment of dividends or stock
purchases or redemptions pursuant to Section 1053 of the Oklahoma Corporate Act,
or (iv) any transaction from which the director derived an improper personal
benefit.
 
     Section 1031 of the Oklahoma Corporate Act permits an Oklahoma corporation
to indemnify any persons who are, or are threatened to be made, parties to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of such corporation), by reason of the fact that such person is or was an
officer, director, employee or agent of such corporation, or is or was serving
at the request of such corporation as a director, officer, employee or agent of
another corporation or enterprise. The indemnity may include expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding, provided such person acted in good faith and in a manner he
reasonably believed to be in or not opposed to the corporation's best interests
and, with respect to any criminal action or proceeding, had no reasonable cause
to believe that his conduct was unlawful. An Oklahoma corporation may indemnify
any persons who were or are parties, or are threatened to be made a party, to
any threatened, pending or completed action or suit by or in the right of the
corporation by reason of the fact that such person is or was a director,
officer, employees or agent of such corporation, or enterprise. The indemnity
may include expenses (including attorneys' fees) actually and reasonably
incurred by such person in connection with the defense or settlement of such
action or suit, provided such person acted in good faith and in a manner he
reasonably believed to be in or not opposed to the corporation's best interest
except that no indemnification is permitted without judicial approval if the
officer is adjudged to be liable to the corporation.
 
                                      II-1
<PAGE>   79
 
Where an officer or director is successful on the merits or otherwise in the
defense of any action referred to above, the corporation must indemnify him
against the expenses which such officer or director has actually and reasonably
incurred.
 
     The Company's certificate of incorporation and bylaws provide for
indemnification of directors and officers of the Company and persons who serve
at the request of the Company as a director or officer of another corporation in
which the Company owns stock for all liabilities, expenses, (including
attorneys' fees) and costs incurred in a legal proceeding in which he is a party
by reason of his having been an officer or director. The Bylaws, however,
exclude indemnification for matters in which the officer or director is adjudged
to have been guilty of gross negligence or willful misconduct.
 
     These indemnification provisions may be sufficiently broad to permit
indemnification of the Registrant's officers and directors for liabilities
(including reimbursement of expenses incurred) arising under the Securities Act
of 1933 as amended (the "Securities Act"). In the opinion of the Securities and
Exchange Commission, indemnification for liabilities arising under the
Securities Act is against public policy and, therefore, unenforceable.
Accordingly, these indemnification provisions may not limit the liability of
directors and executive officers under the Securities Act.
 
     The Underwriting Agreement filed as Exhibit 1.1 to this Registration
Statement provides for indemnification by the Underwriters of the Registrant and
its officers and directors for certain liabilities arising under the Securities
Act, or otherwise.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
     In February, 1995, the Company re-issued to Christiana Bank two stock
purchase warrants for the purchase of a total of 127,907 shares of Common Stock.
These warrants were redeemed by the Company and canceled in August, 1995.
 
     In 1996, the Company issued Incentive Stock Options to three of its
executives as described in the Prospectus in the section
"Management -- Executive Compensation."
 
     In 1996, the Company sold 461,992 shares of Common Stock to certain of its
executive officers and one other employee for a total consideration of $100,000,
payable in the form of notes receivable due in April, 1997.
 
     The issuance of 200 shares of Convertible Preferred Stock on January 1,
1996, and the issuance immediately prior to the effectiveness of this
Registration Statement, of 586,847 shares of Common Stock upon the conversion of
149 shares of such Convertible Preferred Stock, are described in the Prospectus
in the "Certain Transactions" section.
 
     All of the above-described transactions were exempt from registration under
Section 4(2) of the Securities Act and Rule 506 promulgated thereunder as
transactions by an issuer not involving any public offering.

ITEM 17. UNDERTAKINGS.
    
 
     The undersigned hereby undertakes to provide to the Underwriters, at the
Closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described in Item 14, or otherwise, the
Registrant has been advised that, in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable.
 
     In the event that a claim for indemnification against such liabilities
(other than the payment by the Registrant of expenses incurred or paid by a
director, officer of controlling person of the Registrant in the successful
defense of an action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the Registrant will treat the information omitted from the form of
     prospectus filed as part of this Registration Statement in reliance upon
     Rule 430A and contained in a form of prospectus filed by the Registrant
     under Rule 424(b)(1), or (4), or 497(h) under the Securities Act as part of
     this Registration Statement as of the time the Commission declares it
     effective.
 
          (2) For purposes of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the Offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

On behalf of the Several
Underwriters named on
Schedule I attached hereto.

Ladies and Gentlemen:

                    Continental Natural Gas, Inc., an Oklahoma corporation (the
"Company"), proposes to sell to you and the other underwriters named on
Schedule I to this Agreement (the "Underwriters"), for whom you are acting as
Representatives, an aggregate of 1,800,000 shares (the "Company Shares") of the
Company's Common Stock, $0.01 par value (the "Common Stock").  Adams
Affiliates, Inc., an Oklahoma corporation (the "Selling Shareholder"), proposes
to sell an aggregate of 300,000 shares (the "Selling Shareholder Shares") of
Common Stock to the Underwriters.  The Company Shares and the Selling
Shareholder Shares are sometimes collectively called the "Firm Shares."  In
addition, the Company proposes to grant to the Underwriters an option to
purchase up to an additional 315,000 shares (the "Option Shares") of Common
Stock from it for the purpose of covering over-allotments in connection with
the sale of the Firm Shares.  The Firm Shares and the Option Shares are
together called the "Shares."

                    1.       Sale and Purchase of the Shares.   On the basis of
the representations,
<PAGE>   2
warranties and agreements contained in, and subject to the terms and conditions
of, this Agreement:

                    (a)      The Company and the Selling Shareholder agree to
            sell to each of the Underwriters, and each of the Underwriters
            agrees, severally and not jointly, to purchase from the Company and
            the Selling Shareholder, at $_____ per share (the "Initial Price"),
            the number of Firm Shares set forth opposite the name of such
            Underwriter on Schedule I to this Agreement.

                    (b)      The Company grants to the several Underwriters an
            option to purchase, severally and not jointly, all or any part of
            the Option Shares at the Initial Price.  The number of Option
            Shares to be purchased by each Underwriter shall be the same
            percentage (adjusted by the Representatives to eliminate fractions)
            of the total number of Option Shares to be purchased by the
            Underwriters as such Underwriter is purchasing of the Firm Shares.
            Such option may be exercised only to cover over-allotments in the
            sales of the Firm Shares by the Underwriters and may be exercised
            in whole or in part at any time on or before 12:00 noon, New York
            time, on the business day before the Firm Shares Closing Date (as
            defined below), and only once thereafter within 30 days after the
            date of this Agreement, in each case upon written or telegraphic
            notice, or verbal or telephonic notice confirmed by written or
            telegraphic notice, by the Representatives to the Company no later
            than 12:00 noon, New York time on the business day before the Firm
            Shares Closing Date or at least two business days before the Option
            Shares Closing Date (as defined below), as the case may be, setting
            forth the number of Option Shares to be purchased and the time and
            date (if other than the Firm Shares Closing Date) of such purchase.

                    2.       Delivery and Payment.  Delivery by the Company and
the Selling Shareholder of the Firm Shares to the Representatives for the
respective accounts of the Underwriters, and payment of the purchase price by
certified or official bank check or checks payable in New York Clearing House
(next day) funds to the Company and the Selling Shareholder, shall take place
at the offices of_________________________________________________________, at
10:00 a.m., New York time, on the third business day following the date of this
Agreement, or at such time on such other date, not later than 10 business days
after the date of this Agreement, as shall be agreed upon by the Company, the
Selling Shareholder and the Representatives (such time and date of delivery and
payment are called the "Firm Shares Closing Date").

                    In the event the option with respect to the Option Shares
is exercised, delivery by the Company of the Option Shares to the
Representatives for the respective accounts of the Underwriters and payment of
the purchase price by certified or official bank check or checks payable in New
York Clearing House (next day) funds to the Company and the Selling Shareholder
shall take place at the offices of____________________________________________
specified above at the time and on the date (which may be the same date as, but
in no event shall be earlier than, the Firm Shares Closing Date) specified in
the notice referred to in Section 1(b) (such time and date of delivery and
payment are


                                     -2-
<PAGE>   3
called the "Option Shares Closing Date").  The Firm Shares Closing Date and the
Option Shares Closing Date are called, individually, a "Closing Date" and,
together, the "Closing Dates."

                    Certificates evidencing the Shares shall be registered in
such names and shall be in such denominations as the Representatives shall
request at least two full business days before the Firm Shares Closing Date or,
in the case of Option Shares, on the day of notice of exercise of the option as
described in Section l(b) and shall be made available to the Representatives
for checking and packaging, at such place as is designated by the
Representatives, on the full business day before the Firm Shares Closing Date
(or the Option Shares Closing Date in the case of the Option Shares).

                    Certificates in negotiable form for the total number of
Selling Shareholder Shares have been placed in custody with BankBoston, N.A. as
custodian (the "Custodian") pursuant to a Selling Shareholder Power of Attorney
and a Custody Agreement (collectively, the "Custodian Agreement") executed by
the Selling Shareholder for delivery of the Selling Shareholder Shares.  The
Selling Shareholder specifically agrees that the Selling Shareholder Shares to
be sold hereunder by the Selling Shareholder, represented by the certificates
held in custody for the Selling Shareholder under the Custodian Agreement, are
subject to the interest of such Underwriters hereunder, that the arrangements
made by the Selling Shareholder for such custody are to that extent
irrevocable, and that the obligations of the Selling Shareholder hereunder
shall not be terminable by any act or deed of the Selling Shareholder, or by
any other person, firm or corporation, including the Company or the
Underwriters, or by the occurrence of any other event or events, except as set
forth in the Custodian Agreement.  If any such event should occur prior to the
delivery to the Underwriters of the Selling Shareholder Shares to be sold
hereunder by the Selling Shareholder, certificates for such Selling Shareholder
Shares shall be delivered by the Custodian in accordance with the terms and
conditions of this Agreement as if such event had not occurred.  The Custodian
is authorized to receive and acknowledge receipt of the proceeds of sale of the
Selling Shareholder Shares against delivery of such Selling Shareholder Shares.

                    3.       Registration Statement and Prospectus; Public
Offering.  The Company has prepared in conformity with the requirements of the
Securities Act of 1933, as amended (the "Securities Act"), and the published
rules and regulations thereunder (the "Rules") adopted by the Securities and
Exchange Commission (the "Commission") a registration statement on Form S-1
(No. 333-25719), including a preliminary prospectus relating to the Shares, and
has filed with the Commission the Registration Statement (as hereinafter
defined) and such amendments thereof as may have been required to the date of
this Agreement.  Copies of such Registration Statement (including all
amendments thereof) and of the related preliminary prospectus have heretofore
been delivered by the Company to you.  The term "preliminary prospectus" means
any preliminary prospectus (as described in Rule 430 of the Rules) included at
any time as a part of the Registration Statement.  The Registration Statement
as amended at the time and on the date it becomes effective (the "Effective
Date"), including all exhibits and information, if any, deemed to be part of
the Registration Statement pursuant to Rule 424(b) and Rule 430A of the Rules,
is called the "Registration Statement."  The term "Prospectus" means the
prospectus in the form first used to

                                     -3-
<PAGE>   4
confirm sales of the Shares (whether such prospectus was included in the
Registration Statement at the time of effectiveness or was subsequently filed
with the Commission pursuant to Rule 424(b) of the Rules).

                    The Company understands that the Underwriters propose to
make a public offering of the Shares, as set forth in and pursuant to the
Prospectus, as soon after the Effective Date and the date of this Agreement as
the Representatives deem advisable.  The Company hereby confirms that the
Underwriters and dealers have been authorized to distribute or cause to be
distributed each preliminary prospectus and are authorized to distribute the
Prospectus (as from time to time amended or supplemented if the Company
furnishes amendments or supplements thereto to the Underwriters).

                    4.       Representations and Warranties of the Company.

            (a)     The Company hereby represents and warrants to each
Underwriter as follows:

                    (i)      On the Effective Date the Registration Statement
            complied, and on the date of the Prospectus, on the date any
            post-effective amendment to the Registration Statement shall become
            effective, on the date any supplement or amendment to the
            Prospectus is filed with the Commission and on each Closing Date,
            the Registration Statement and the Prospectus (and any amendment
            thereof or supplement thereto) will comply, in all material
            respects, with the applicable provisions of the Securities Act and
            the Rules and the Securities Exchange Act of 1934, as amended (the
            "Exchange Act"), and the rules and regulations of the Commission
            thereunder; the Registration Statement did not, as of the Effective
            Date, contain any untrue statement of a material fact or omit to
            state any material fact required to be stated therein or necessary
            in order to make the statements therein not misleading; and on the
            other dates referred to above neither the Registration Statement
            nor the Prospectus, nor any amendment thereof or supplement
            thereto, will contain any untrue statement of a material fact or
            will omit to state any material fact required to be stated therein
            or necessary in order to make the statements therein not
            misleading.  When any related preliminary prospectus was first
            filed with the Commission (whether filed as part of the
            Registration Statement or any amendment thereto or pursuant to Rule
            424(a) of the Rules) and when any amendment thereof or supplement
            thereto was first filed with the Commission, such preliminary
            prospectus as amended or supplemented complied in all material
            respects with the applicable provisions of the Securities Act and
            the Rules and did not contain any untrue statement of a material
            fact or omit to state any material fact required to be stated
            therein or necessary in order to make the statements therein not
            misleading.  Notwithstanding the foregoing, the Company makes no
            representation or warranty as to the paragraph with respect to
            stabilization on the inside front cover page of the Prospectus and
            the statements contained under the caption "Underwriting" in the
            Prospectus.  The Company acknowledges that the statements referred
            to in the previous sentence constitute the only information
            furnished in writing


                                     -4-
<PAGE>   5
            by the Representatives on behalf of the several Underwriters
            specifically for inclusion in the Registration Statement, any
            preliminary prospectus or the Prospectus.

                    (ii)     The financial statements of the Company (including
            all notes and schedules thereto) included in the Registration
            Statement and Prospectus present fairly the financial position, the
            results of operations and cash flows and the shareholders' equity
            and the other information purported to be shown therein of the
            Company at the respective dates and for the respective periods to
            which they apply; and such financial statements have been prepared
            in conformity with generally accepted accounting principles,
            consistently applied throughout the periods involved, and all
            adjustments necessary for a fair presentation of the results for
            such periods have been made.

                    (iii)    Coopers & Lybrand L.L.P., whose reports are filed
            with the Commission as a part of the Registration Statement, are
            and, during the periods covered by their reports, were independent
            public accountants as required by the Securities Act and the Rules.

                    (iv)     The Company has been duly incorporated and is
            validly existing as a corporation in good standing under the laws
            of the State of Oklahoma.  The Company has no subsidiary or
            subsidiaries and does not control, directly or indirectly, any
            corporation, partnership, joint venture, limited liability company,
            association or other business organization, except as disclosed in
            Exhibit 21 to the Registration Statement (and for purposes of this
            Section 4, the term "the Company" shall, where appropriate, include
            such entities).  Except as disclosed in Exhibit 21 to the
            Registration Statement, all of the issued and outstanding equity
            interests of each of such entities are owned directly by the
            Company; all such interests have been duly authorized and validly
            issued and are fully paid and nonassessable and are owned free and
            clear of any pledge, lien, encumbrance, security interest or other
            claim (other than the pledge of the same to ING Capital Corporation
            under the Company's principal loan facility); there are no
            outstanding rights, subscriptions, warrants, calls, preemptive
            rights, options or other agreements of any kind with respect to the
            equity interests of such entities.  The Company is duly qualified
            and in good standing as a foreign corporation in each jurisdiction
            in which the character or location of its assets or properties
            (owned, leased or licensed) or the nature of its business makes
            such qualification necessary except for such jurisdictions where
            the failure to so qualify would not have a material adverse effect
            on the assets or properties, business, results of operations or
            financial condition of the Company.  Except as disclosed in the
            Registration Statement and the Prospectus, the Company does not
            own, lease or license any asset or property or conduct any business
            outside the United States of America.  The Company has all
            requisite corporate power and authority, and all necessary
            authorizations, approvals, consents, orders, licenses, certificates
            and permits of and from all governmental or regulatory bodies or
            any other person or entity, to own, lease and license its assets
            and properties and conduct its businesses as now being conducted
            and


                                     -5-
<PAGE>   6
            as described in the Registration Statement and the Prospectus
            except for such authorizations, approvals, consents, orders,
            material licenses, certificates and permits the failure to so
            obtain would not have a material adverse effect upon the assets or
            properties, business, results of operations, prospects or condition
            (financial or otherwise) of the Company; no such authorization,
            approval, consent, order, license, certificate or permit contains a
            materially burdensome restriction other than as disclosed in the
            Registration Statement and the Prospectus; and the Company has all
            such corporate power and authority, and such authorizations,
            approvals, consents, orders, licenses, certificates and permits to
            enter into, deliver and perform this Agreement and to issue and
            sell the Shares (except as may be required under the Securities Act
            and state and foreign Blue Sky laws).

                    (v)      The Company owns or possesses adequate and
            enforceable rights to use all trademarks, trademark applications,
            trade names, service marks, copyrights, copyright applications,
            licenses, know-how and other similar rights and proprietary
            knowledge (collectively, "Intangibles") necessary for the conduct
            of its business as described in the Registration Statement and the
            Prospectus.  The Company has not received any notice of, or to its
            best knowledge is not aware of, any infringement of or conflict
            with asserted rights of others with respect to any Intangibles
            which, singly or in the aggregate, if the subject of an unfavorable
            decision, ruling or finding, would have a material adverse effect
            upon the assets or properties, business, results of operations,
            prospects or condition (financial or otherwise) of the Company.

                    (vi)     The Company has good title to each of the items of
            personal property which are reflected in the financial statements
            referred to in Section 4(a)(iii) or are referred to in the
            Registration Statement and the Prospectus as being owned by it and
            valid and enforceable leasehold interests in each of the items of
            real and personal property which are referred to in the
            Registration Statement and the Prospectus as being leased by it, in
            each case free and clear of all liens, encumbrances, claims,
            security interests and defects, other than those described in the
            Registration Statement and the Prospectus and those which do not
            and will not have a material adverse effect upon the assets or
            properties, business, results of operations or financial condition
            of the Company.

                    (vii)    Except as described in the Registration Statement
            and the Prospectus, there is no litigation or governmental or other
            proceeding or investigation before any court or before or by any
            public body or board pending or, to the Company's best knowledge,
            threatened (and the Company does not know of any basis therefor)
            against, or involving the assets, properties or business of, the
            Company which would materially adversely affect the value or the
            operation of any such assets or properties or the business, results
            of operations, prospects or condition (financial or otherwise) of
            the Company.

                    (viii)   Subsequent to the respective dates as of which
            information is given in the Registration Statement and the
            Prospectus, except as described therein,  (i) there has not been
            any material adverse change in the assets or properties, business,
            results of operations, prospects or condition (financial or
            otherwise), of the Company, whether or not arising from
            transactions in the ordinary course of business; (ii) the Company
            has not sustained any material loss or interference with its
            assets, businesses or properties (whether owned or leased) from
            fire, explosion, earthquake, flood or other calamity, whether or
            not covered by insurance, or from any labor dispute or any court or
            legislative or other governmental action, order or decree; and
            (iii) and since the date of the latest balance sheet included in
            the Registration Statement and the Prospectus, except as reflected
            therein, the Company has not (a) issued any securities or incurred
            any liability or obligation, direct or contingent, for borrowed
            money, except such liabilities or obligations incurred in the
            ordinary course of business, (b) entered into any transaction not
            in the ordinary course of business or (c) declared or paid any
            dividend or made any distribution on any shares of its stock or
            redeemed, purchased or otherwise acquired or agreed to redeem,
            purchase or otherwise acquire any shares of its stock.

                    (ix)     All contracts and other documents required to be
            filed as exhibits to the Registration Statement have been filed
            with the Commission as exhibits to the Registration Statement.
            There is no document or contract of a character required to be
            described in the Registration Statement or Prospectus or to be
            filed as an exhibit to the Registration Statement which is not
            described or filed as required.  Each agreement listed in the
            Exhibits to the Registration Statement is in full force and effect
            and is valid and enforceable by and against the Company in
            accordance with its terms, assuming the due authorization,
            execution and delivery thereof by each of the other parties
            thereto.  Neither the Company, nor to the best of the Company's
            knowledge, any other party is in default in the observance or
            performance of any term or obligation to be performed by it under
            any such agreement, and no event has occurred which with notice or
            lapse of time or both would constitute such a default, in any such
            case which default or event would have a material adverse effect on
            the assets or properties, business, results of operations,
            prospects or condition (financial or otherwise) of the Company.  No
            default exists, and no event has occurred which with notice or
            lapse of time or both would constitute a default, in the due
            performance and observance of any term, covenant or condition, by
            the Company of any other agreement or instrument to which the
            Company is a party or by which it or its properties or business may
            be bound or affected which default or event would have a material
            adverse effect on the assets or properties, business, results of
            operations, prospects or condition (financial or otherwise) of the
            Company.

                    (x)      The Company is not in violation of any term or
            provision of its charter or bylaws or of any franchise, license,
            permit, judgment, decree, order, statute, rule or regulation, where
            the consequences of such violation would have a material adverse
            effect on the assets or properties, business, results of
            operations, prospects or condition

                                     -7-
<PAGE>   8
            (financial or otherwise) of the Company.

                    (xi)     Neither the execution, delivery and performance of
            this Agreement by the Company nor the consummation of any of the
            transactions contemplated hereby (including, without limitation,
            the issuance and sale by the Company of the Shares) will give rise
            to a right to terminate or accelerate the due date of any payment
            due under, or conflict with or result in the breach of any term or
            provision of, or constitute a default (or an event which with
            notice or lapse of time or both would constitute a default) under,
            or require any consent or waiver under, or result in the execution
            or imposition of any lien, charge or encumbrance upon any
            properties or assets of the Company pursuant to the terms of, any
            indenture, mortgage, deed of trust or other agreement or instrument
            to which the Company is a party or by which it or any of its
            properties or businesses is bound, or any franchise, license,
            permit, judgment, decree, order, statute, rule or regulation
            applicable to the Company or violate any provision of the charter
            or bylaws of the Company, except for such consents or waivers which
            have already been obtained and are in full force and effect.

                    (xii)    The Company has an authorized and outstanding
            capital stock as set forth under the caption "Capitalization" in
            the Prospectus.  All of the outstanding shares of Common Stock have
            been duly and validly issued and are fully paid and nonassessable
            and none of them was issued in violation of any preemptive or other
            similar right.  The Shares, when issued and sold pursuant to this
            Agreement, will be duly and validly issued, fully paid and
            nonassessable and none of them will be issued in violation of any
            preemptive or other similar right.  Except as disclosed in the
            Registration Statement and the Prospectus, there is no outstanding
            option, warrant or other right calling for the issuance of, and
            there is no commitment, plan or arrangement to issue, any share of
            stock of the Company or any security convertible into, or
            exercisable or exchangeable for, such stock.  The Common Stock and
            the Shares conform in all material respects to all statements in
            relation thereto contained in the Registration Statement and the
            Prospectus.

                    (xiii)   No holder of any security of the Company has the
            right to have any security owned by such holder included in the
            Registration Statement or to demand registration of any security
            owned by such holder during the period ending 180 days after the
            date of this Agreement.  Each shareholder, director and executive
            officer of the Company has delivered to the Representatives his
            enforceable written agreement that he will not, for a period of 180
            days after the date of this Agreement, offer for sale, sell,
            distribute, grant any option for the sale of, or otherwise dispose
            of, directly or indirectly, or exercise any registration rights
            with respect to, any shares of Common Stock (or any securities
            convertible into, exercisable for, or exchangeable for any shares
            of Common Stock) owned by him, without the prior written consent of
            the Representatives; provided, that, such shareholder, director or
            executive officer shall be permitted under such agreement to make
            gifts of shares of Common Stock so long as the donee of the shares

                                     -8-
<PAGE>   9
            acquires and holds them subject to the restrictions of such
            agreement.

                    (xiv)    All necessary corporate action has been duly and
            validly taken by the Company to authorize the execution, delivery
            and performance of this Agreement and the issuance and sale of the
            Shares by the Company.  This Agreement has been duly and validly
            authorized, executed and delivered by the Company and constitutes
            legal, valid and binding obligations of the Company enforceable
            against the Company in accordance with their respective terms,
            except (A) as the enforceability thereof may be limited by
            bankruptcy, insolvency, reorganization, moratorium or other similar
            laws affecting the enforcement of creditors' rights generally and
            by general equitable principles and (B) to the extent that rights
            to indemnity or contribution under this Agreement may be limited by

            human health and safety, the environment or hazardous or toxic
            substances or wastes, pollutants or contaminants ("Environmental
            Laws").  The Company reasonably has concluded that the costs and
            liabilities associated with compliance by the Company with
            Environmental Laws are not likely to have, singly or in the
            aggregate, a material adverse effect on the properties, assets,
            operations, business, business prospects or financial condition of
            the Company.

                    (xvi)    The Company is not involved in any labor dispute
            nor, to the knowledge of the Company, is any such dispute
            threatened, which dispute would have a material adverse effect on
            the assets or properties, business, results of operations,
            prospects or condition (financial or otherwise) of the Company.

                    (xvii)   No transaction has occurred between or among the
            Company and any of its officers or directors or any affiliate or
            affiliates of any such officer or director that is required to be
            described in and is not described in the Registration Statement and
            the Prospectus.

                    (xviii)  The Company has not taken, nor will it take,
            directly or indirectly, any action designed to or which might
            reasonably be expected to cause or result in, or which has
            constituted or which might reasonably be expected to constitute,
            the stabilization or manipulation of the price of the Common Stock
            to facilitate the sale or resale of any of the Shares.

                    (xix)    The Company has filed all Federal, state, local
            and foreign tax returns which are required to be filed through the
            date hereof, or has received extensions thereof, and has paid all
            taxes shown on such returns and all assessments received by it to
            the extent that the same are material and have become due.

                    (xx)     The Shares have been duly authorized for quotation
            on the National Association of Securities Dealers Automated
            Quotation ("NASDAQ") National Market.

                    (xxi)    The Company has complied with all of the
            requirements and filed the required forms as specified in Florida
            Statutes Section 517.075.

            (b)     The Selling Shareholder hereby represents and warrants to
each Underwriter as follows:

                    (i)      To the best knowledge of the Selling Shareholder,
            the representations and warranties of the Company contained in
            Section 4(a) hereof are true and correct; the Selling Shareholder
            has reviewed and is familiar with the Registration Statement as
            originally filed with the Commission and the Prospectus and has no
            knowledge of any material fact, condition or information not
            disclosed in such Prospectus that has adversely affected or could
            adversely affect the condition (financial or otherwise), earnings,
            business affairs or business prospects of the Company; to the best
            knowledge of the Selling Shareholder, the Prospectus does not
            include an untrue statement of a material fact or omit to state a
            material fact necessary in order to make the statements therein, in
            the light of the circumstances under which they were made, not
            misleading; and the Selling Shareholder is not prompted to sell the
            Selling Shareholder Shares to be sold hereunder by the Selling
            Shareholder by any information concerning the Company that is not
            set forth in the Prospectus.

                    (ii)     When the Registration Statement shall become
            effective, and at all times subsequent thereto up to the Closing
            Date (and if any Option Shares are purchased, on the Second Closing
            Date), such parts of the Registration Statement and any amendments
            and supplements thereto and the Prospectus as specifically refer to
            the Selling Shareholder will not contain an untrue statement of a
            material fact or omit to state a material fact required to be
            stated therein or necessary to make the statements therein not
            misleading.

                    (iii)    Each of this Agreement and the Custodian Agreement
            is a legal, valid and binding agreement of the Selling Shareholder,
            enforceable against the Selling Shareholder in accordance with
            their respective terms except as such enforceability may be limited
            by bankruptcy, reorganization, insolvency, moratorium and other
            similar laws affecting creditors' rights generally or by the
            application of equitable principles.

                    (iv)     Neither the execution, delivery and performance of
            this Agreement and the Custodian Agreement, the consummation of the
            transactions contemplated herein and therein, including the
            issuance, sale and delivery of the Selling Shareholder Shares nor
            compliance with the terms and provisions hereof, will (i) conflict
            with or result in a breach of any of the terms and provisions of,
            or constitute a default (or an event which


                                    -10-
<PAGE>   11
            with notice or lapse of time, or both, would constitute a default)
            or require consent under, or result in the creation or imposition
            of, any lien, encumbrance, security interest, claim or other
            restriction of any nature whatsoever upon any property or assets of
            the Selling Shareholder, pursuant to the terms of any agreement,
            instrument or permit to which the Selling Shareholder is a party or
            by which any of the Selling Shareholder's properties or assets may
            be bound; (ii) violate or conflict with any provisions of any
            permit, judgment, decree, order, statute, rule or regulation of any
            court or any public, governmental or regulatory agency or body
            having jurisdiction over the Selling Shareholder or any of the
            Selling Shareholder's properties or assets.  No permit of or with
            any court or any public, governmental or regulatory agency or body
            having jurisdiction over the Selling Shareholder or any of the
            Selling Shareholder's properties or assets is required for the
            execution, delivery and performance of this Agreement and the
            consummation of the transactions contemplated herein, including the
            sale and delivery of the Selling Shareholder Shares, except the
            registration under the Securities Act of the Selling Shareholder
            Shares and such permits as may be required under state or foreign
            securities or "Blue Sky" laws in connection with the purchase and
            distribution of the Selling Shareholder Shares by the Underwriters.

                    (v)      The Selling Shareholder now has, and at the
            Closing Date will have good and marketable title to the Selling
            Shareholder Shares to be sold hereunder by the Selling Shareholder,
            free and clear of any pledge, lien, security interest, charge,
            claim, equity or encumbrance of any kind, other than pursuant to
            this Agreement; the Selling Shareholder has full right, power and
            authority to sell, transfer and deliver such Selling Shareholder
            Shares; the Selling Shareholder Shares have been duly and validly
            authorized and issued, are fully paid and non-assessable, conform
            to the description thereof in the Prospectus, and have not been
            issued in violation of or subject to any preemptive right or other
            right to subscribe for or purchase such securities; and, upon
            delivery of such Selling Shareholder Shares to be sold hereunder by
            the Selling Shareholder and payment of the purchase price therefor
            as contemplated in this Agreement, each of the Underwriters will
            receive good and marketable title to the Selling Shareholder
            Shares, free and clear of any pledge, lien, security interest,
            charge, claim, equity or encumbrance of any kind.

                    (vi)     No person has any right to acquire from the
            Selling Shareholder any Shares to be sold hereunder and the Selling
            Shareholder is under no obligation, whether absolute or contingent,
            to sell any such Shares to any person, except as disclosed in the
            Prospectus.

                    (vii)    The Selling Shareholder has not taken and will not
            take, directly or indirectly, any action designed to, or which
            might be reasonably expected to, cause or result in stabilization
            or manipulation of the price of the Common Stock, or any other
            securities convertible into or exchangeable or exercisable for
            shares of Common Stock.

obligations of the

            the Prospectus or otherwise) shall have been complied with to the
            satisfaction of the Representatives.

                    (c)      The representations and warranties of the Company
            contained in this Agreement and in the certificates delivered

            the Company in this Agreement are true and correct on and as of
            such Closing Date with the same effect as if made on such Closing
            Date and the Company has performed all covenants and agreements and
            satisfied all conditions contained in this Agreement required to be
            performed or satisfied by it at or prior to such Closing Date.

                    (e) The Representatives shall have received on the
            Effective Date, at the time this Agreement is executed and on each
            Closing Date a signed letter from Coopers & Lybrand L.L.P.,
            addressed to the Representatives and dated, respectively, the
            Effective Date, the date of this Agreement and each such Closing

                    the Registration Statement and the Prospectus and reported
                    on by them comply as to form in all material respects with
                    the applicable


                                    -12-
<PAGE>   13
                    accounting requirements of the Securities Act and the
                    Rules;

                             (ii)  on the basis of a reading of the amounts
                    included in the Registration Statement and the Prospectus
                    under the headings "Summary Financial Information" and
                    "Selected Financial Data," carrying out certain procedures
                    (but not an examination in accordance with generally
                    accepted auditing standards) which would not necessarily
                    reveal matters of significance with respect to the comments
                    set forth in such letter, a reading of the minutes of the
                    meetings of the shareholders and directors of the Company,
                    and inquiries of certain officials of the Company who have
                    responsibility for financial and accounting matters of the
                    Company as to transactions and events subsequent to the
                    date of the latest audited financial statements, except as
                    disclosed in the Registration Statement and the Prospectus,
                    nothing came to their attention which caused them to
                    believe that:

                                     (A)  the amounts in "Summary Financial
                             Information," and "Selected Financial Data"
                             included in the Registration Statement and the
                             Prospectus do not agree with the corresponding
                             amounts in the audited and unaudited financial
                             statements from which such amounts were derived;
                             or

                                     (B)  with respect to the Company, there
                             were, at a specified date not more than five
                             business days prior to the date of the letter, any
                             increases in the current liabilities and long-term
                             liabilities of the Company or any decreases in net
                             income or in working capital or the shareholders'
                             equity in the Company, as compared with the
                             amounts shown on the Company's audited balance
                             sheet for the fiscal year ended December 31, 1996
                             and the three months ended March 31, 1997 included
                             in the Registration Statement; and

                             (iii)  they have performed certain other
                    procedures as a result of which they determined that
                    certain information of an accounting, financial or
                    statistical nature (which is limited to accounting,
                    financial or statistical information derived from the
                    general accounting records of the Company) set forth in the
                    Registration Statement and the Prospectus and reasonably
                    specified by the Representatives agrees with the accounting
                    records of the Company.

                    References to the Registration Statement and the Prospectus
                    in this paragraph (e) are to such documents as amended and
                    supplemented at the date of the letter.

                    (f)      The Representatives shall have received on each
            Closing Date from Albright & Rusher, a Professional Corporation,
            counsel for the Company and the Selling Shareholder, an opinion,
            addressed to the Representatives and dated such Closing Date,


                                    -13-

            and stating in effect that:

                             (i)  The Company has been duly organized and is
                    validly existing as a corporation in good standing under
                    the laws of the State of Oklahoma.  To the best of such
                    counsel's knowledge, except as provided in Exhibit 21 to
                    the Registration Statement, the Company has no subsidiaries
                    and does not control, directly or indirectly, any
                    corporation, partnership, joint venture, association or
                    other business organization.  Each of the entities listed
                    on Exhibit 21 to the Registration Statement (the
                    "Subsidiaries") has been duly organized and is validly
                    existing in good standing under the laws of its state of
                    organization.  The Company and each Subsidiary is duly
                    qualified and in good standing as a foreign corporation in
                    each jurisdiction in which the character or location of its
                    assets or properties (owned, leased or licensed) or the
                    nature of its businesses makes such qualification
                    necessary, except for such jurisdictions where the failure
                    to so qualify would not have a material adverse effect on
                    the assets or properties, business, results of operations,
                    prospects or condition (financial or otherwise) of the
                    Company and the Subsidiaries, taken as a whole.

                             (ii)  The Company and each Subsidiary has all
                    requisite corporate power and authority to own, lease and
                    license its assets and properties and conduct its business
                    as now being conducted and as described in the Registration
                    Statement and the Prospectus; and the Company has all
                    requisite corporate power and authority and all necessary
                    authorizations, approvals, consents, orders, licenses,
                    certificates and permits to enter into, deliver and perform
                    this Agreement and to issue and sell the Shares other than
                    those required under the Securities Act and state and
                    foreign Blue Sky laws.

                             (iii)  The Company has authorized and issued
                    capital stock as set forth in the Registration Statement
                    and the Prospectus; the certificates evidencing the Shares
                    are in due and proper legal form and have been duly
                    authorized for issuance by the Company; all of the
                    outstanding shares of Common Stock of the Company have been
                    duly and validly authorized and have been duly and validly
                    issued and are fully paid and nonassessable and none of
                    them was issued in violation of any preemptive or other
                    similar right.  The Shares when issued and sold pursuant to
                    this Agreement will be duly and validly issued,
                    outstanding, fully paid and nonassessable and none of them
                    will have been issued in violation of any preemptive or
                    other similar right.  To the best of such counsel's
                    knowledge, except as disclosed in the Registration
                    Statement and the Prospectus, there is no outstanding
                    option, warrant or other right calling for the issuance of,
                    and no commitment, plan or arrangement to issue, any share
                    of stock of the Company or any security convertible into,
                    exercisable for, or exchangeable for stock of the Company.
                    The Common Stock and the Shares conform in all material
                    respects

                    to the descriptions thereof contained in the Registration
                    Statement and the Prospectus.

                             (iv)    The agreement of the Company's
                    shareholders, directors and officers stating that for a
                    period of 180 days from the date of this Agreement they
                    will not, without the Representatives' prior written
                    consent, sell, grant any option for the sale of, or
                    otherwise dispose of, directly or indirectly, any shares of
                    Common Stock (or any securities convertible into,
                    exercisable for, or exchangeable for any shares of Common
                    Stock) owned by them has been duly and validly delivered by
                    such persons and constitutes the legal, valid and binding
                    obligation of each such person enforceable against each
                    such person in accordance with its terms, except as the
                    enforceability thereof may be limited by applicable
                    bankruptcy, insolvency, reorganization, moratorium or other
                    similar laws affecting the enforcement of creditors' rights
                    generally and by general equitable principles.

                             (v)  All necessary corporate action has been duly
                    and validly taken by the Company to authorize the
                    execution, delivery and performance of this Agreement and
                    the issuance and sale of the Shares.  This Agreement has
                    been duly and validly authorized, executed and delivered by
                    the Company and this Agreement constitutes the legal, valid
                    and binding obligation of the Company enforceable against
                    the Company in accordance with its terms except (A) as such
                    enforceability may be limited by applicable bankruptcy,
                    insolvency, reorganization, moratorium or other similar
                    laws affecting the enforcement of creditors' rights
                    generally and by general equitable principles and (B) to
                    the extent that rights to indemnity or contribution under
                    this Agreement may be limited by Federal or state
                    securities laws or the public policy underlying such laws.

                             (vi)  Neither the execution, delivery and
                    performance of this Agreement by the Company nor the
                    consummation of any of the transactions contemplated hereby
                    (including, without limitation, the issuance and sale by
                    the Company of the Shares) will give rise to a right to
                    terminate or accelerate the due date of any payment due
                    under, or conflict with or result in the breach of any term
                    or provision of, or constitute a default (or any event
                    which with notice or lapse of time, or both, would
                    constitute a default) under, or require consent or waiver
                    under, or result in the execution or imposition of any
                    lien, charge or encumbrance upon any properties or assets
                    of the Company or any Subsidiary pursuant to the terms of
                    any indenture, mortgage, deed trust, note or other
                    agreement or instrument of which such counsel is aware and
                    to which the Company or any Subsidiary is a party or by
                    which it or any of its properties or businesses is bound,
                    or any franchise, license, permit, judgment, decree, order,
                    statute, rule or regulation of which such counsel is aware
                    or violate any provision of the charter or bylaws of the
                    Company or any Subsidiary.

                             (vii)  To the best of such counsel's knowledge, no
                    default exists, and no event has occurred which with notice
                    or lapse of time, or both, would constitute a default, in
                    the due performance and observance of any term, covenant or
                    condition by the Company or any Subsidiary of any
                    indenture, mortgage, deed of trust, note or any other
                    agreement or instrument to which the Company or any
                    Subsidiary is a party or by which it or any of its assets
                    or properties or businesses may be bound or affected, where
                    the consequences of such default would have a material and
                    adverse effect on the assets, properties, business, results
                    of operations, prospects or condition (financial or
                    otherwise) of the Company and the Subsidiaries, taken as a
                    whole.

                             (viii)  To the best of such counsel's knowledge,
                    neither the Company nor any Subsidiary is in violation of
                    any term or provision of its charter or bylaws or any
                    franchise, license, permit, judgment, decree, order,
                    statute, rule or regulation, where the consequences of such
                    violation would have a material and adverse effect on the
                    assets or properties, businesses, results of operations,
                    prospects or condition (financial or otherwise) of the
                    Company and the Subsidiaries, taken as a whole.

                             (ix)  No consent, approval, authorization or order
                    of any court or governmental agency or body is required for
                    the performance of this Agreement by the Company or the
                    consummation of the transactions contemplated hereby or
                    thereby, except such as have been obtained under the
                    Securities Act and such as may be required under state
                    securities or Blue Sky laws in connection with the purchase
                    and distribution of the Shares by the several Underwriters.

                             (x)  To the best of such counsel's knowledge,
                    except as disclosed in the Registration Statement and
                    Prospectus, there is no litigation or governmental or other
                    proceeding or investigation, before any court or before or
                    by any public body or board pending or threatened against,
                    or involving the assets, properties or businesses of, the
                    Company or any Subsidiary which would have a material
                    adverse effect upon the assets or properties, business,
                    results of operations, prospects or condition (financial or
                    otherwise) of the Company and the Subsidiaries, taken as a
                    whole.

                             (xi)    The statements in the Prospectus under the
                    captions "Description of Capital Stock," "Management's
                    Discussion & Analysis of Financial Condition and Results of
                    Operations - Liquidity and Capital Resources," "Business,"
                    "Shares Eligible for Future Sale,", "Management," and
                    "Certain Transactions," insofar as such statements
                    constitute a summary of documents referred to therein or
                    matters of law, are fair summaries in all material respects
                    and accurately present the information called for with
                    respect to such documents and matters.  To the best

                    knowledge of such counsel, all contracts and other
                    documents required to be filed as exhibits to, or described
                    in, the Registration Statement have been so filed with the
                    Commission or are fairly described in the Registration
                    Statement, as the case may be.

                             (xii)   The Agreement has been duly executed and
                    delivered by or on behalf of the Selling Shareholder.

                             (xiii)  To the best knowledge of such counsel, the
                    Selling Shareholder has good and valid title to the Selling
                    Shareholder Shares, free and clear of any pledge, lien,
                    security interest, charge, claim, equity or encumbrance of
                    any kind and has full right, power and authority to sell,
                    transfer and deliver the Selling Shareholder Shares.  By
                    delivery of a certificate or certificates therefor, the
                    Selling Shareholder will transfer good and valid title to
                    such Selling Shareholder Shares free and clear of any
                    pledge, lien, security interest, charge, claim, equity or
                    encumbrance of any kind.

                             (xiv)   The Custody Agreement executed and
                    delivered by the Selling Shareholder is a valid,
                    irrevocable instrument, and except as rights to indemnity
                    thereunder may be limited under applicable law, is binding
                    and enforceable against the Selling Shareholder in
                    accordance with its terms, subject to bankruptcy,
                    insolvency, and similar laws governing the rights of
                    creditors generally and to the discretion of courts in
                    granting equitable remedies.  The attorneys-in-fact
                    appointed under the Selling Shareholder's Power of Attorney
                    have the power and authority to sell, on behalf of the
                    Selling Shareholder, such of the Shares as are to be sold
                    by the Selling Shareholder on the terms set forth in the
                    Underwriting Agreement.

                    To the extent deemed advisable by such counsel, they may
rely as to matters of fact on certificates of responsible officers of the
Company and public officials and on the opinions of other counsel satisfactory
to the Representatives as to matters which are governed by laws other than the
laws of the State of Oklahoma and the Federal laws of the United States;
provided that such counsel shall state that in their opinion the Underwriters
and they are justified in relying on such other opinions.  Copies of such
certificates and other opinions shall be furnished to the Representatives and
counsel for the Underwriters.

                    In addition, such counsel shall state that such counsel has
participated in conferences with officers and other representatives of the
Company, representatives of the Representatives and representatives of the
independent certified public accountants of the Company, at which conferences
the contents of the Registration Statement and the Prospectus and related
matters were discussed and, although such counsel is not passing upon and does
not assume any responsibility for the accuracy, completeness or fairness of the
statements contained in the


                                    -17-

Registration Statement and the Prospectus (except as specified in the foregoing
opinion), on the basis of the foregoing, no facts have come to the attention of
such counsel which lead such counsel to believe that the Registration Statement
at the time it became effective (except with respect to the financial
statements and notes and schedules thereto and other financial data, as to
which such counsel need express no belief) contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading, or that the
Prospectus as amended or supplemented (except with respect to the financial
statements and notes schedules thereto and other financial data, as to which
such counsel need make no statement) on the date thereof contained any untrue
statement of a material fact or omitted to state a material fact necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading.

                    (g)      The Representatives shall have received on each
            Closing Date from Hall, Estill, Hardwick, Gable, Golden & Nelson,
            P.C., counsel for the Company, an opinion, addressed to the
            Representatives and dated such Closing Date, and stating in effect
            that:

                             (i)  The Registration Statement, all preliminary
                    prospectuses and the Prospectus and each amendment or
                    supplement thereto (except for the financial statements and
                    schedules and other financial and statistical data included
                    therein, as to which such counsel expresses no opinion)
                    comply as to form in all material respects with the
                    requirements of the Securities Act and the Rules.
                             (ii)  The Registration Statement has become
                    effective under the Securities Act, and no stop order
                    suspending the effectiveness of the Registration Statement
                    has been issued and no proceedings for that purpose have
                    been instituted or are threatened, pending or contemplated.

                    In addition, such counsel shall state that such counsel has
participated in conferences with officers and other representatives of the
Company, representatives of the Representatives and representatives of the
independent certified public accountants of the Company, at which conferences
the contents of the Registration Statement and the Prospectus and related
matters were discussed and, although such counsel is not passing upon and does
not assume any responsibility for the accuracy, completeness or fairness of the

have come to the attention of such counsel which lead such counsel to believe
that the Registration Statement at the time it became effective (except with
respect to the financial statements and notes and schedules thereto and other
financial data, as to which such counsel need express no belief) contained any
untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or that the Prospectus as amended or supplemented (except with
respect to the financial statements and notes schedules thereto and other
financial data, as to which such counsel need make no statement) on the date
thereof contained any untrue statement of a material fact or omitted to state a
material fact necessary in order to make the statements therein, in the light
of the circumstances

                    (h)      All proceedings taken in connection with the sale
            of the Firm Shares and the Option Shares as herein contemplated
            shall be reasonably satisfactory in form and substance to the
            Representatives and their counsel and the Underwriters shall have

            L.L.P. such documents as they may reasonably request for the
            purpose of enabling them to pass upon such matters.

                    (i)      The Representatives shall have received on each
            Closing Date a certificate, addressed to the Representatives, and
            dated such Closing Date, of an executive officer of the Company to
            the effect that the signer of such certificate has reviewed and
            understands the provisions of Section 517.075 of the Florida
            Statutes, and represents that the Company has complied, and at all
            times will comply, with all provisions of Section 517.075 and
            further, that as of such Closing Date, neither the Company nor any
            of its affiliates does business with the government of Cuba or with

                    (j)      The Representatives shall have received the

            Date.

                    6.       Covenants.

                    (A) The Company covenants and agrees as follows:

                             (i)     The Company shall prepare the Prospectus

                    unless the Company has furnished the Representatives a copy
                    for its review prior to filing and shall not file any such
                    proposed amendment or supplement to which the
                    Representatives reasonably object.  The Company shall use
                    its best efforts to prevent the issuance of any such stop
                    order and, if issued, to obtain as soon as possible the
                    withdrawal thereof.

                             (ii)    If, at any time when a prospectus relating
                    to the Shares is required to be delivered under the
                    Securities Act and the Rules, any event occurs as a result
                    of which the Prospectus as then amended or supplemented
                    would include any untrue statement of a material fact or
                    omit to state any material fact necessary to make the
                    statements therein in the light of the circumstances under
                    which they were made not misleading, or if it shall be
                    necessary to amend or supplement the Prospectus to comply
                    with the Securities Act or the Rules, the Company promptly
                    shall prepare and file with the Commission, subject to the
                    second sentence of paragraph (a) of this Section 6(A), an
                    amendment or supplement which shall correct such statement
                    or omission or an amendment which shall effect such
                    compliance.

                             (iii)   The Company shall make generally available
                    to its security holders and to the Representatives as soon
                    as practicable, but not later than 45 days after the end of
                    the 12-month period beginning at the end of the fiscal
                    quarter of the Company during which the Effective Date
                    occurs (or 90 days if such 12-month period coincides with
                    the Company's fiscal year), an earning statement (which
                    need not be audited) of the Company, covering such 12-month
                    period, which shall satisfy the provisions of Section 11(a)
                    of the Securities Act or Rule 158 of the Rules.

                             (iv)    The Company shall furnish to the
                    Representatives and counsel for the Underwriters, without
                    charge, signed copies of the Registration Statement
                    (including all exhibits thereto and amendments thereof) and
                    to each other Underwriter a copy of the Registration
                    Statement (without exhibits thereto) and all amendments
                    thereof and, so long as delivery of a prospectus by an
                    Underwriter or dealer may be required by the Securities Act
                    or the Rules, as many copies of any preliminary prospectus
                    and the Prospectus and any amendments thereof and
                    supplements thereto as the Representatives may reasonably
                    request.

                             (v)     The Company shall cooperate with the
                    Representatives and their counsel in endeavoring to qualify
                    the Shares for offer and sale under the laws of such
                    jurisdictions as the Representatives may designate and
                    shall maintain such qualifications in effect so long as
                    required for the distribution of the Shares; provided,
                    however, that the Company shall not be required in
                    connection therewith, as a condition thereof, to qualify as
                    a foreign corporation or to execute a general consent to
                    service of process in any jurisdiction or subject itself to
                    taxation as doing business in any jurisdiction.

                             (vi)    For a period of five years after the date
                    of this Agreement, the Company shall supply to the
                    Representatives, and to each other Underwriter who may so
                    request in writing, copies of such financial statements and
                    other periodic and special reports as the Company may from
                    time to time distribute generally to the holders of any
                    class of its capital stock and to furnish to the
                    Representatives a copy of each annual or other report it
                    shall be required to file with the Commission (including
                    the Report on Form SR required by Rule 463 of the Rules).

                             (vii)  Without the prior written consent of the
                    Representatives, for a period of 180 days after the date of
                    this Agreement, the Company shall not issue, sell or
                    register with the Commission (other than on Form S-8 or on
                    any successor form), or otherwise dispose of, directly or
                    indirectly, any equity securities of the Company (or any
                    securities convertible into or exercisable or exchangeable
                    for equity securities of the Company), except for the
                    issuance of the Shares pursuant to the Registration
                    Statement and the issuance of shares pursuant to the
                    Company's existing stock option plans or bonus plans.  In
                    the event that during this period, (i) any shares are
                    issued pursuant to the Company's existing stock option
                    plans or bonus plans or (ii) any registration is effected
                    on Form S-8 or on any successor form, the Company shall
                    obtain the written agreement of such grantee or purchaser
                    or holder of such registered securities that, for a period
                    of 180 days after the date of this Agreement, such person
                    will not, without the prior written consent of the
                    Representatives, offer for sale, sell, distribute, grant
                    any option for the sale of, or otherwise dispose of,
                    directly or indirectly, or exercise any registration rights
                    with respect to, any shares of Common Stock (or any
                    securities convertible into, exercisable for, or
                    exchangeable for any shares of Common Stock) owned by such
                    person.

                             (viii)  On or before completion of this offering,
                    the Company shall make all filings required under
                    applicable securities laws and by the NASDAQ National
                    Market (including any required registration under the
                    Exchange Act).

                    (B)      The Selling Shareholder covenants and agrees with
each of the Underwriters that:


                                    -21-
<PAGE>   22
                             (i)  without the prior written consent of the
                    Representatives, the Selling Shareholder will not sell or
                    offer or contract to sell, except to the Underwriters
                    pursuant to this Agreement, any securities of the Company
                    before the close of business on the 180th day after the
                    commencement of the public offering of the Shares by the
                    Underwriters.

                             (ii)  the Selling Shareholder will cooperate with
                    the Representatives in endeavoring to qualify the Shares
                    for sale under the securities laws of such jurisdictions as
                    the Representatives may reasonably designate in writing and
                    will make such applications, file such documents, and
                    furnish such information as may be reasonably required for
                    that purpose.

                    (C)      The Company agrees to pay, or reimburse if paid by
the Representatives, whether or not the transactions contemplated hereby are
consummated or this Agreement is terminated, all costs and expenses incident to
the public offering of the Shares and the performance of the obligations of the
Company under this Agreement including those relating to:  (i) the preparation,
printing, filing and distribution of the Registration Statement including all
exhibits thereto, each preliminary prospectus, the Prospectus, all amendments
and supplements to the Registration Statement and the Prospectus, and the
printing, filing and distribution of this Agreement; (ii) the preparation and
delivery of certificates for the Shares to the Underwriters; (iii) the
registration or qualification of the Shares for offer and sale under the
securities or Blue Sky laws of the various jurisdictions referred to in Section
6(A)(e), including the reasonable fees and disbursements of counsel for the
Underwriters in connection with such registration and qualification and the
preparation, printing, distribution and shipment of preliminary and
supplementary Blue Sky memoranda; (iv) the furnishing (including costs of
shipping and mailing) to the Representatives and to the Underwriters of copies
of each preliminary prospectus, the Prospectus and all amendments or
supplements to the Prospectus, and of the several documents required by this
Section to be so furnished, as may be reasonably requested for use in
connection with the offering and sale of the Shares by the Underwriters or by
dealers to whom Shares may be sold; (v) the filing fees of the National
Association of Securities Dealers, Inc. in connection with its review of the
terms of the public offering; (vi) the furnishing (including costs of shipping
and mailing) to the Representatives and to the Underwriters of copies of all
reports and information required by Section 6(A)(f); (vii) inclusion of the
Shares for quotation on the NASDAQ National Market; and (viii) all transfer
taxes, if any, with respect to the sale and delivery of the Shares by the
Company to the Underwriters.  The Selling Shareholder agrees to reimburse the
Company for 14.29% of such costs promptly after request therefor by the
Company.  Subject to the provisions of Section 9, the Underwriters agree to
pay, whether or not the transactions contemplated hereby are consummated or
this Agreement is terminated, all costs and expenses incident to the
performance of the obligations of the Underwriters under this Agreement not
payable by the Company pursuant to the preceding sentence, including, without
limitation, the fees and disbursements of counsel for the Underwriters.

                     7.      Indemnification.

                    (a)      The Company and the Selling Shareholder, jointly
            and severally, agree to indemnify and hold harmless each
            Underwriter and each person, if any, who controls any Underwriter
            within the meaning of Section 15 of the Securities Act or Section
            20 of the Exchange Act against any and all losses, claims, damages
            and liabilities, joint or several (including any reasonable
            investigation, legal and other expenses incurred in connection
            with, and any amount paid in settlement of, any action, suit or
            proceeding or any claim asserted) (collectively, "Losses"), to
            which they, or any of them, may become subject under the Securities
            Act, the Exchange Act or other Federal or state law or regulation
            (a "Statute"), at common law or otherwise, insofar as such losses,
            claims, damages or liabilities arise out of or are based upon any
            untrue statement or alleged untrue statement of a material fact
            contained in any preliminary prospectus, the Registration Statement
            or the Prospectus or any amendment thereof or supplement thereto,
            or arise out of or are based upon any omission or alleged omission
            to state therein a material fact required to be stated therein or
            necessary to make the statements therein not misleading; provided,
            however, that such indemnity shall not inure to the benefit of any
            Underwriter (or any person controlling such Underwriter) on account
            of any losses, claims, damages or liabilities arising from the sale
            of the Shares to any person by such Underwriter if such untrue
            statement or omission or alleged untrue statement or omission was
            made in such preliminary prospectus, the Registration Statement or
            the Prospectus, or such amendment or supplement, in reliance upon
            and in conformity with information furnished in writing to the
            Company by the Representatives on behalf of any Underwriter
            specifically for use therein; and provided further that the
            foregoing indemnity agreement with respect to any preliminary
            prospectus shall not inure to the benefit of any Underwriter from
            whom the person asserting any such Losses purchased Shares, or any
            person controlling such Underwriter, if a copy of the Prospectus
            (as then amended or supplemented if the Company shall have
            furnished any amendments or supplements thereto) was not sent or
            given by or on behalf of such Underwriter to such person, if
            required by law so to have been delivered, at or prior to the
            written confirmation of the sale of the Shares to such person, and
            if the Prospectus (as so amended or supplemented) would have cured
            the defect giving rise to such Loss; and provided further that the
            Selling Shareholder will not be liable in any case for any amount
            in excess of the aggregate proceeds received by the Selling
            Shareholder.  THE COMPANY AND THE SELLING SHAREHOLDER WILL BE
            RESPONSIBLE UNDER THIS AGREEMENT FOR ANY AND ALL LOSSES WHETHER OR
            NOT IT IS ALLEGED OR PROVEN THAT THE LOSSES AROSE OUT OF OR
            RESULTED FROM THE SOLE OR CONCURRENT NEGLIGENCE OR GROSS NEGLIGENCE
            OF ANY UNDERWRITER, OR THE SOLE OR CONCURRENT STRICT LIABILITY
            IMPOSED ON ANY UNDERWRITER, OR THE SOLE OR CONCURRENT LIABILITY
            IMPOSED VICARIOUSLY ON ANY UNDERWRITER, UNDER A STATUTE, AT COMMON
            LAW OR OTHERWISE.  This indemnity agreement will be in addition to
            any liability which the Company and the Selling Shareholder may
            otherwise have.

<PAGE>   24
                    (b)      Each Underwriter agrees, severally and not
            jointly, to indemnify and hold harmless the Company, the Selling
            Shareholder, each person, if any, who controls the Company and the
            Selling Shareholder within the meaning of Section 15 of the
            Securities Act or Section 20 of the Exchange Act, each director of
            the Company, and each officer of the Company who signs the
            Registration Statement, to the same extent as the foregoing
            indemnity from the Company to each Underwriter, but only insofar as
            such losses, claims, damages or liabilities arise out of or are
            based upon any untrue statement or omission or alleged untrue
            statement or omission which was made in any preliminary prospectus,
            the Registration Statement or the Prospectus, or any amendment
            thereof or supplement thereto, contained in the last paragraph of
            the cover page, in the paragraph relating to stabilization on the
            inside front cover page of the Prospectus and the statements
            contained under the caption "Underwriting" in the Prospectus;
            provided, however, that the obligation of each Underwriter to
            indemnify the Company, the Selling Shareholder, as the case may be,
            (including any controlling person, director or officer thereof)
            shall be limited to the net proceeds received by the Company or the
            Selling Shareholder, as the case may be, from such Underwriter.


                    (c)      Any party that proposes to assert the right to be
            indemnified under this Section will, promptly after receipt of
            notice of commencement of any action, suit or proceeding against
            such party in respect of which a claim is to be made against an
            indemnifying party or parties under this Section, notify each such
            indemnifying party of the commencement of such action, suit or
            proceeding, enclosing a copy of all papers served.  No
            indemnification provided for in Section 7(a) or 7(b) shall be
            available to any party who shall fail to give notice as provided in
            this Section 7(c) if the party to whom notice was not given was
            unaware of the proceeding to which such notice would have related
            and was prejudiced by the failure to give such notice but the
            omission so to notify such indemnifying party of any such action,
            suit or proceeding shall not relieve it from any liability that it
            may have to any indemnified party for contribution or otherwise
            than under this Section.  In case any such action, suit or
            proceeding shall be brought against any indemnified party and it
            shall notify the indemnifying party of the commencement thereof,
            the indemnifying party shall be entitled to participate in, and, to
            the extent that it shall wish, jointly with any other indemnifying
            party similarly notified, to assume the defense thereof, with
            counsel reasonably satisfactory to such indemnified party, and
            after notice from the indemnifying party to such indemnified party
            of its election so to assume the defense thereof and the approval
            by the indemnified party of such counsel, the indemnifying party
            shall not be liable to such indemnified party for any legal or
            other expenses, except as provided below and except for the
            reasonable costs of investigation subsequently incurred by such
            indemnified party in connection with the defense thereof.  The
            indemnified party shall have the right to employ its counsel in any
            such action, but the fees and expenses of such counsel shall be at
            the expense of such indemnified party unless (i) the employment of
            counsel by such indemnified party has been authorized in


                                    -24-
<PAGE>   25
            writing by the indemnifying parties, (ii) the indemnified party
            shall have reasonably concluded that there may be a conflict of
            interest between the indemnifying parties and the indemnified party
            in the conduct of the defense of such action (in which case the
            indemnifying parties shall not have the right to direct the defense
            of such action on behalf of the indemnified party) or (iii) the
            indemnifying parties shall not have employed counsel to assume the
            defense of such action within a reasonable time after notice of the
            commencement thereof, in each of which cases the fees and expenses
            of counsel shall be at the expense of the indemnifying parties.  An
            indemnifying party shall not be liable for any settlement of any
            action, suit, proceeding or claim effected without its written
            consent.

                    8.       Contribution.  In order to provide for just and
equitable contribution in circumstances in which the indemnification provided
for in Section 7(a) is due in accordance with its terms but for any reason is
held to be unavailable from the Company or the Selling Shareholder, the
Company, the Selling Shareholder and the Underwriters shall contribute to the
aggregate losses, claims, damages and liabilities (including any investigation,
legal and other expenses reasonably incurred in connection with, and any amount
paid in settlement of, any action, suit or proceeding or any claims asserted,
but after deducting any contribution received by the Company or the Selling
Shareholder, from persons other than the Underwriters, such as persons who
control the Company within the meaning of the Securities Act, officers of the
Company who signed the Registration Statement and directors of the Company, who
may also be liable for contribution) to which the Company or the Selling
Shareholder and one or more of the Underwriters may be subject in such
proportion as is appropriate to reflect the relative benefits received by the
Company or the Selling Shareholder, on the one hand and the Underwriters on the
other from the offering of the Shares or, if such allocation is not permitted
by applicable law or indemnification is not available as a result of the
indemnifying party not having received notice as provided in Section 7 hereof,
in such proportion as is appropriate to reflect not only the relative benefits
referred to above but also the relative fault of the Company or the Selling
Shareholder, on the one hand and the Underwriters on the other in connection
with the statements or omissions which resulted in such losses, claims,
damages, liabilities or expenses, as well as any other relevant equitable
considerations.  The relative benefits received by the Company, the Selling
Shareholder and the Underwriters shall be deemed to be in the same proportion
as (x) the total proceeds from the offering (net of underwriting discounts but
before deducting expenses) received by the Company and the Selling Shareholder,
as set forth in the table on the cover page of the Prospectus, bear to (y) the
underwriting discounts received by the Underwriters, as set forth in the table
on the cover page of the Prospectus.  The relative fault of the Company, the
Selling Shareholder or the Underwriters shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a
material fact related to information supplied by the Company, the Selling
Shareholder or the Underwriters and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.  The Company, the Selling Shareholder and the Underwriters agree that
it would not be just and equitable if contribution pursuant to this Section 8
were determined by pro rata allocation (even if the Underwriters were treated
as one entity for such purpose) or by any other


                                    -25-
<PAGE>   26
method of allocation which does not take account of the equitable
considerations referred to above.  Notwithstanding the provisions of this
Section 8, (i) in no case shall any Underwriter (except as may be provided in
the Agreement Among Underwriters) be liable or responsible for any amount in
excess of the underwriting discount applicable to the Shares purchased by such
Underwriter hereunder, and (ii) the Company shall be liable and responsible for
any amount in excess of such underwriting discount; provided, however, that no
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.  For purposes of this
Section 8, each person, if any, who controls an Underwriter within the meaning
of Section 15 of the Securities Act or Section 20(a) of the Exchange Act shall
have the same rights to contribution as such Underwriter, and each person, if
any, who controls the Company within the meaning of the Section 15 of the
Securities Act or Section 20(a) of the Exchange Act, each officer of the
Company who shall have signed the Registration Statement and each director of
the Company shall have the same rights to contribution as the Company, subject
in each case to clauses (i) and (ii) in the immediately preceding sentence of
this Section 8.  Any party entitled to contribution will, promptly after
receipt of notice of commencement of any action, suit or proceeding against
such party in respect of which a claim for contribution may be made against
another party or parties under this Section, notify such party or parties from
whom contribution may be sought, but the omission so to notify such party or
parties from whom contribution may be sought shall not relieve the party or
parties from whom contribution may be sought from any other obligation it or
they may have hereunder or otherwise than under this Section.  No party shall
be liable for contribution with respect to any action, suit, proceeding or
claim settled without its written consent.  The Underwriter's obligations to
contribute pursuant to this Section 8 are several in proportion to their
respective underwriting commitments and not joint.

                    9.       Termination.  This Agreement may be terminated
with respect to the Shares to be purchased on a Closing Date by the
Representatives by notifying the Company and the Selling Shareholder at any
time

                    (a)      in the absolute discretion of the Representatives
            at or before any Closing Date: (i) if on or prior to such date, any
            domestic or international event or act or occurrence has materially
            disrupted, or in the opinion of the Representatives will in the
            future materially disrupt, the securities markets; (ii) if there
            has occurred any new outbreak or material escalation of hostilities
            or other calamity or crisis the effect of which on the financial
            markets of the United States is such as to make it, in the judgment
            of the Representatives, inadvisable to proceed with the offering;
            (iii) if there shall be such a material adverse change in general
            financial, political or economic conditions or the effect of
            international conditions on the financial markets in the United
            States is such as to make it, in the judgment of the
            Representatives, inadvisable or impracticable to market the Shares;
            (iv) if trading in the Shares has been suspended by the Commission
            or trading generally on the New York Stock Exchange, Inc. or on the
            American Stock Exchange, Inc.  has been suspended or limited, or
            minimum or maximum ranges for prices for securities shall have been
            fixed, or maximum ranges for prices for securities have been


                                    -26-
<PAGE>   27
            required, by said exchanges or by order of the Commission, the
            National Association of Securities Dealers, Inc., or any other
            governmental or regulatory authority; or (v) if a banking
            moratorium has been declared by any state or Federal authority, or

                    (b)      at or before any Closing Date, that any of the
            conditions specified in Section 5 shall not have been fulfilled
            when and as required by this Agreement.

                    If this Agreement is terminated pursuant to any of its
provisions, the Company shall not be under any liability to any Underwriter,
and no Underwriter shall be under any liability to the Company, except that (y)
if this Agreement is terminated by the Representatives or the Underwriters
because of any failure, refusal or inability on the part of the Company to
comply with the terms or to fulfill any of the conditions of this Agreement,
the Company will reimburse the Underwriters for all out-of-pocket expenses
(including the reasonable fees and disbursements of their counsel) incurred by
them in connection with the proposed purchase and sale of the Shares or in
contemplation of performing their obligations hereunder and (z) no Underwriter
who shall have failed or refused to purchase the Shares agreed to be purchased
by it under this Agreement, without some reason sufficient hereunder to justify
cancellation or termination of its obligations under this Agreement, shall be
relieved of liability to the Company or to the other Underwriters for damages
occasioned by its failure or refusal.


                    10.      Substitution of Underwriters.  If one or more of
the Underwriters shall fail (other than for a reason sufficient to justify the
cancellation or termination of this Agreement under Section 9) to purchase on
any Closing Date the Shares agreed to be purchased on such Closing Date by such
Underwriter or Underwriters, the Representatives may find one or more
substitute underwriters to purchase such Shares or make such other arrangements
as the Representatives may deem advisable or one or more of the remaining
Underwriters may agree to purchase such Shares in such proportions as may be
approved by the Representatives, in each case upon the terms set forth in this
Agreement.  If no such arrangements have been made by the close of business on
the business day following such Closing Date,

                    (a)      if the number of Shares to be purchased by the
            defaulting Underwriters on such Closing Date shall not exceed 10%
            of the Shares that all the Underwriters are obligated to purchase
            on such Closing Date, then each of the nondefaulting Underwriters
            shall be obligated to purchase such Shares on the terms herein set
            forth in proportion to their respective obligations hereunder;
            provided, that in no event shall the maximum number of Shares that
            any Underwriter has agreed to purchase pursuant to Section 1 be
            increased pursuant to this Section 10 by more than one-ninth of
            such number of Shares without the written consent of such
            Underwriter, or

                    (b)      if the number of Shares to be purchased by the
            defaulting Underwriters on such Closing Date shall exceed 10% of
            the Shares that all the Underwriters are obligated


                                    -27-
<PAGE>   28
            to purchase on such Closing Date, then the Company shall be
            entitled to an additional business day within which it may, but is
            not obligated to, find one or more substitute underwriters
            reasonably satisfactory to the Representatives to purchase such
            Shares upon the terms set forth in this Agreement.

                    In any such case, either the Representatives or the Company
shall have the right to postpone the applicable Closing Date for a period of
not more than five business days in order that necessary changes and
arrangements (including any necessary amendments or supplements to the
Registration Statement or Prospectus) may be effected by the Representatives
and the Company.  If the number of Shares to be purchased on such Closing Date
by such defaulting Underwriter or Underwriters shall exceed 10% of the Shares
that all the Underwriters are obligated to purchase on such Closing Date, and
none of the nondefaulting Underwriters or the Company shall make arrangements
pursuant to this Section within the period stated for the purchase of the
Shares that the defaulting Underwriters agreed to purchase, this Agreement
shall terminate with respect to the Shares to be purchased on such Closing Date
without liability on the part of any nondefaulting Underwriter to the Company
and without liability on the part of the Company, except in both cases as
provided in Sections 6(B), 7, 8 and 9.  The provisions of this Section shall
not in any way affect the liability of any defaulting Underwriter to the
Company or the nondefaulting Underwriters arising out of such default.  A
substitute underwriter hereunder shall become an Underwriter for all purposes
of this Agreement.


                    11.      Miscellaneous.  The respective agreements,
representations, warranties, indemnities and other statements of the Company or
its officers and of the Underwriters set forth in or made pursuant to this
Agreement shall remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or the Company or any of
the officers, directors or controlling persons referred to in Sections 7 and 8
hereof, and shall survive delivery of and payment for the Shares.  The
provisions of Sections 6(B), 7, 8 and 9 shall survive the termination or
cancellation of this Agreement.

                    This Agreement has been and is made for the benefit of the
Underwriters and the Company and their respective successors and assigns, and,
to the extent expressed herein, for the benefit of persons controlling any of
the Underwriters, or the Company, and directors and officers of the Company,
and their respective successors and assigns, and no other person shall acquire
or have any right under or by virtue of this Agreement.  The term "successors
and assigns" shall not include any purchaser of Shares from any Underwriter
merely because of such purchase.

                    All notices and communications hereunder shall be in
writing and mailed or delivered or by telephone or telegraph if subsequently
confirmed in writing, (a) if to the Representatives, c/o Oppenheimer & Co.,
Inc. at the address set forth above, (b) if to the Company, to its agent for
service as such agent's address appears on the cover page of the Registration
Statement, and (c) if to the Selling Shareholder in care of the Company.

     Re:  Registration Statement on Form S-1, as amended
          (No. 333-25719)

Ladies and Gentlemen:

     We have acted as counsel for Continental Natural Gas, Inc., an Oklahoma
corporation (the "Company"), in connection with the various legal matters
relating to the filing of a Registration Statement on Form S-1 (the
"Registration Statement") under the Securities Act of 1933, as amended,
relating to 2,415,000 shares of the common stock of the Company, $0.01 par
value per share (the "Common Stock") consisting of up to 2,115,000 shares to be
sold by the Company and up to 300,000 shares to be sold by certain of the
shareholders of the Company (the "Selling Shareholders"), including, in each
case, those shares subject to an option to purchase granted to the several
underwriters to cover over-allotments.

     We have examined such corporate records of the Company, such laws and such
other information as we have deemed relevant, including the Company's
Certificate of Incorporation, as amended, Amended and Restated Bylaws,
resolutions adopted by the Board of Directors of the Company relating to such
offering and certificates received from state officials and from officers of
the Company. In delivering this opinion, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals, the
conformity to the originals of all documents submitted to us as certified,
photostatic or conformed copies, and the correctness of all statements
submitted to us by officers of the Company.

     Based solely on the foregoing, the undersigned is of the opinion that:

     1.   The Company is a corporation duly incorporated, validly existing and
          in good standing under the laws of the State of Oklahoma.

     2.   The Common Stock being offered by the Company and each of the Selling
          Shareholders, if sold and issued in the manner described in the
          Registration Statement, will be validly issued and outstanding and
          will be fully paid and non-assessable.

     We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the use of our name in the Registration Statement. We also
consent to you filing copies of this opinion as an exhibit to the Registration
Statement with agencies of such states as you deem necessary in the course of
complying with the laws of such states regarding the issuance of the Common
Stock sold.


                                        Very truly yours,

                             STATEMENT OF AGREEMENT

       NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration this day paid by
each party to the other, the receipt and sufficiency of which are hereby
acknowledged, Employer and Employee agree as follows:

       1.     Employment.  Employer hereby agrees to continue the employment of
Employee and Employee hereby agrees to continue to provide Employee's services
to Employer upon the terms and conditions herein stated.

       2.     Term.  Subject to the provisions for termination as hereinafter
provided, the term of this Agreement shall begin as of the date hereof, and
shall terminate on December 31, 1999.

       3.     Compensation.

              (a)    Salary.  For services rendered by Employee under this
       Agreement, Employer shall pay Employee a salary of One Hundred Fifty
       Thousand Dollars ($150,000.00) per annum, payable in twenty-six (26)
       equal bi-weekly installments.  On January 1 of each calendar year during
       the term hereof, the
<PAGE>   2
       annual salary payable to Employee pursuant to this paragraph 3(a) shall
       be increased by a percentage equal to the percentage increase as of such
       date, if any, in the Official Consumers Price Index published by the
       Bureau of Labor Statistics of the U. S. Department of Labor, applicable
       to the smallest geographic region which includes Tulsa, Oklahoma, with
       reference to the Official Consumers Price Index for January 1 of the
       previous year.

              (b)    Bonus.  For the calendar year 1997 and for all subsequent
       calendar years during the term of this Agreement, Employer shall pay
       Employee a yearly bonus equal as follows:

                     (i)  If the Adjusted Income for such calendar year is
              equal to or greater than the Initial Threshold, but less than the
              Second Threshold, the yearly bonus payable to Employee shall
              equal the product obtained by multipying (A) $50,000 by (B) a
              fraction (I) the numerator of which is the amount by which the
              Adjusted Income for such calendar year exceeds the Initial
              Threshold and (II) the denominator of which is the difference
              between the Second Threshold and the Initial Threshold;

                     (ii)  If the Adjusted Income is equal to or greater than
              the Second Threshold, but less than the Third Threshold, the
              yearly bonus payable to Employee shall equal $50,000;

                     (iii)  If the Adjusted Income is equal to or greater than
              the Third Threshold, but less than the Fourth Threshold, the
              yearly bonus payable to Employee shall equal $100,000; or

                     (iv)  If the Adjusted Income is equal to or greater than
              the Fourth Threshold, the yearly bonus payable to Employee shall
              equal $150,000.

       The Thresholds for the 1997 calendar year shall be as follows:

              Initial Threshold = $4,400,000
              Second Threshold = $5,500,000
              Third Threshold = $6,600,000
              Fourth Threshold = $7,700,000

       For any calendar year subsequent to 1997, the Initial Threshold shall be
       an amount equal to 20% of Average Daily Adjusted Equity for the previous
       calendar year, the Second Threshold will be 25% of such Average Daily
       Adjusted Equity, the Third Threshold will be 30% of such Average Daily
       Adjusted Equity and the Fourth Threshold will be 35% of such Average
       Daily Adjusted Equity .  As used herein, the term "Adjusted





                                       2
<PAGE>   3
       Income" shall mean, for the calendar year in question, the income of
       Employer before income taxes plus depreciation, depletion and
       amortization and any other noncash items.  As used herein, the term
       "Average Daily Adjusted Equity" shall mean, for the calendar year in
       question, the average of the Adjusted Equity for the year in question;
       such Adjusted Equity being an amount, determined each day, equal to (A)
       the stockholders' equity of Employer as of the last day of the previous
       calendar year less (B) the then Unutilized IPO Proceeds.  As of any day,
       the then Unutilized IPO Proceeds shall be an amount equal to (I) the net
       proceeds, after all expenses, to Employer raised pursuant to the initial
       public offering ("IPO") consummated by Employer as of the effective date
       of this Agreement less (II) the amount of Employer's long-term debt as
       of such day which has been incurred by Employer since the date of the
       IPO (plus any long-term debt incurred by Employer prior to the IPO if
       incurred in contemplation of the IPO, as determined by Employer, in
       Employer's sole discretion, exercised in good faith).

              Notwithstanding any of the foregoing, for any calendar year
       during which occurs an event which would have been a "Buyout Event"
       under the Employment Agreement (prior to its amendment hereby), the
       bonus payable with respect to the gain realized by Employer as a result
       of such event shall be 1.5%.

              Within thirty (30) days after the end of each calendar month,
       Employer shall make a good faith estimate of the Adjusted Income for
       such calendar month and pay Employee the estimated bonus attributable
       thereto).  Within ninety (90) days after the end of each calendar year
       during the term hereof, an accounting of the actual amounts owed to
       Employee pursuant to this paragraph 3(b) shall be conducted by Employer
       and, to the extent of the difference between the aggregate of the
       estimated monthly payments to Employee and the actual amounts owed by
       Employer to Employee, the party owing such amounts shall make payment to
       the other.  Such payment shall be made within five (5) days after
       delivery of the accounting to Employee.  Any payment not paid on or
       before the due date therefor shall bear interest at a varying rate of
       interest per annum equal to the prime lending rate of Bank of Oklahoma,
       N.A., plus one and one-half percent (1-1/2%).

              If this Agreement becomes effective on any day other than January
       1, the bonus payable to Employee for the first calendar year during
       which this Agreement is effective shall be prorated.  The bonus payable
       to Employee for the portion of such calendar year from January 1 through
       the day prior to the effective date of this Agreement shall be paid
       based upon the terms of the Employment Agreement prior to its amendment
       and restatement hereunder.  The bonus which would have been paid under
       such Employment Agreement prior to its amendment and





                                       3
<PAGE>   4
       restatement hereunder shall be computed for the entire calendar year and
       then multiplied by a fraction, the numerator of which is the number of
       days of such calendar year prior to the effective date of this Agreement
       and the denominator of which is the number of days in such entire
       calendar year.  The bonus payable to Employee for the remaining portion
       of such calendar year shall be paid based upon the terms described in
       this paragraph 3(b), prorated in the same manner as described in the
       preceding sentence (using the number of remaining days in such calendar
       year as the numerator).

              (c) Determination of Adjusted Income and Average Daily Adjusted
       Equity.  The Adjusted Income and Average Daily Adjusted Equity shall be
       determined by the certified public accountant or accounting firm (the
       "CPA") which normally audits the books of Employer.  Such determinations
       shall be made using generally accepted accounting principles,
       consistently applied and consistent with past practices of Employer.
       Such determinations shall be binding on all parties and conclusive in
       all respects; provided, however, Employee shall have the right to audit
       the determinations.  If Employee's audit reveals inconsistencies in the
       determination by the CPA resulting in an error in the amount payable
       hereunder for any twelve-month period in excess of five percent (5%),
       Employer shall bear the cost of Employee's audit.  Otherwise, Employee's
       audit shall be Employee's expense.  After any such audit, once the
       correct amount owed is determined, the party owing the other shall pay
       the amount owed upon demand.

              (d)    Automobile Allowance.  Employer shall also pay Employee at
       the same times Employee is paid salary pursuant to paragraph 3(a) above,
       Four Hundred Dollars ($400.00) per month during the term of this
       Agreement as an automobile allowance.  In consideration thereof and as a
       result of the nature of the services to be performed by Employee,
       Employee shall keep an automobile available and in working condition so
       that Employee can adequately perform the services required to be
       performed by Employee hereunder.

              (e)    Additional Compensation.  The compensation agreed to be
       paid to Employee by Employer in this paragraph 3 shall not operate in
       any manner as a limitation of any type upon or as a direction, express
       or implied, against the exercise by the Board (the "Board") of Directors
       of Employer of its power, authority and discretion to grant additional
       bonuses and/or fees or other additional direct or indirect benefits or
       compensation to or on behalf of Employee if, in the business judgment of
       the Board, such action is merited and in the best interest of Employer.





                                       4
<PAGE>   5
              (f)    Withholding.  The salary and any other compensation paid
       to Employee shall be subject to any and all such payroll and withholding
       deductions as are required by the laws of any jurisdiction, federal,
       state or local, with taxing authority with respect to such salary and
       other compensation.

              (g)    Payments after Termination.  Notwithstanding any other
       provision of this Agreement to the contrary, except as provided in
       paragraph 13 hereof, any payment required pursuant to this paragraph 3
       attributable to any period of time occurring during the term of this
       Agreement shall be made when due despite the fact that such payment is
       due after termination of this Agreement.

       4.     Duties.  To the best of Employee's ability, using reasonable and
prudent judgment and care, Employee shall render such services and perform such
duties as are customary for a Vice-President and Controller in the industry and
as may be requested by Employer from time to time.

       5.     Extent of Services.  Employee shall devote such time and energy
to the furtherance of Employer's business as shall be determined by the Board.
During the term of this Agreement, Employee shall not, directly or indirectly,
alone or as a member of any business entity, or as an officer, director or
stockholder of any corporation, be engaged in or concerned with any other
commercial or business duties or pursuits which would require such substantial
services on the part of Employee that Employee, in Employer's sole opinion,
would be unable to perform the services required to be performed by Employee
hereby.

       6.     Working Facilities and Staff.  Employee shall be furnished with
such facilities, staff and services as are suitable to Employee's position and
adequate for the performance of Employee's duties.

       7.     Expenses.  Employer will reimburse Employee for all such expenses
which Employer, in Employer's sole discretion, deems are reasonably incurred
for promoting the business of Employer, upon the presentation by Employee, from
time to time, of an itemized account of such expenditures.

       8.     Vacations.  During the term of this Agreement, Employee shall be
entitled, during each year of employment with Employer, to a vacation in
accordance with the established company policy of Employer, during which time
Employee's compensation hereunder shall be paid in full.

       9.     Insurance.  During the term of this Agreement, Employer shall
provide to Employee, and pay all premiums for, major medical insurance with
coverage for Employee and Employee's immediate family on terms no less
favorable than is currently provided.





                                       5
<PAGE>   6
       10.    Pension and Profit-sharing Plan.  During the term of this
Agreement, to the extent it is financially reasonable as determined by the
Board, Employer shall maintain in effect any pension and profit-sharing plans
maintained by Employer as of the date hereof and Employee shall be entitled to
participate in such plans on a non-discriminatory basis.

       11.    Memberships.  During the term of this Agreement, Employer shall
maintain its membership at Cedar Ridge Country Club and Employee shall be
designated as the exclusive user thereof, entitled to enjoy all of the rights
and privileges pertaining thereto.  In addition, Employer agrees to pay, on
behalf of Employee, up to Three Thousand Dollars ($3,000.00) per year for dues
and/or fees for club memberships, dinner clubs and/or professional
organizations.

       12.    Disability and Death.  If Employee is unable to perform
Employee's services by reason of illness or incapacity for a period of more
than ninety (90) consecutive days, the compensation otherwise payable to
Employee during the continued period of such illness or incapacity shall be
reduced by fifty percent (50%).  Employee's full compensation shall be
reinstated upon Employee's return to employment and the discharge of Employee's
full duties hereunder.  Notwithstanding anything herein to the contrary,
Employer may terminate this Agreement at any time after Employee shall be
absent from Employee's employment, for whatever cause, for a continuous period
of more than sixty (60) consecutive days, in which event, subject to paragraph
3(g) hereof, all obligations of the Employer hereunder, including Employer's
obligations to pay Employee the compensation provided in paragraph 3 hereof,
shall immediately cease upon any such termination.  In no event, however, shall
any provision of this paragraph 12 be interpreted to limit or restrict
Employee's rights to participate in and receive benefits under the existing
Employer disability plan(s).  Subject to paragraph 3(g) hereof, all of
Employer's obligations hereunder, including Employer's obligations to pay
Employee the compensation provided in paragraph 3 hereof, shall cease
immediately upon Employee's death.  The determination of all periods of time
under this paragraph 12 shall be calculated by including (and counting)
weekends which occur within the applicable period but excluding days of sick
leave, vacation, holidays and other days off, if any, allowed pursuant to
established company policy of Employer.

       13.    Termination for Cause.  Employer may terminate Employee's
employment under this Agreement upon (10) days' notice to Employee after the
occurrence of any of the following events ("Cause Events") unless such events
were caused at the direction of Employer:

              (a)    Any failure by Employee to faithfully perform the
       covenants and agreements of Employee herein stated;





                                       6
<PAGE>   7
              (b)    Willful, gross misconduct by Employee in connection with
       the performance of the covenants and agreements of Employee herein
       stated;

              (c)    If Employee violates any law, rule or regulation which
       violation materially adversely affects Employer or any of Employer's
       subsidiaries or other affiliates (collectively hereinafter referred to
       as the "Employer Companies");

              (d)    If Employee violates any of the provisions of paragraphs
       16 or 17;

              (e)  If Employee converts any property of Employer Companies;

              (f)    If Employee is convicted of any felony which materially
       adversely affects Employer Companies or the ability of Employee to
       perform Employee's duties hereunder; or

              (g)    If Employee is convicted of any lesser crime or offense
       involving property or business of Employer Companies.

In the event of a dispute as to whether a Cause Event has occurred, upon the
request of Employer or Employee, such dispute shall be resolved pursuant to the
expedited procedures of the commercial arbitration rules of the American
Arbitration Association regardless of the amount in controversy, with each
party to bear its own arbitration costs and expenses.  The parties stipulate
that the hearing locale for any such arbitration proceeding will be Tulsa,
Oklahoma.  Judgment upon the award rendered as a result of such arbitration may
be entered in any court having jurisdiction thereof.  The parties further
stipulate that the provisions hereof shall be a complete defense to any suit,
action or proceeding instituted in any federal, state or local court or before
any administrative tribunal with respect to any controversy or dispute arising
out of or relating to whether a Cause Event has occurred.  Upon termination of
Employee's employment under this Agreement as a result of a Cause Event, all of
Employer's obligations hereunder, including Employer's obligations to pay
Employee the compensation provided in paragraph 3 hereof (whether or not then
accrued), shall immediately cease.  Nothing contained herein shall be construed
as limiting in any manner any of the rights or remedies available to Employer
pursuant to this agreement or otherwise with respect to such Cause Event.

       14.    Expiration of Term.  In the event this Agreement is terminated
due to expiration of the term of this Agreement as set forth in paragraph 2
hereof, subject to paragraph 3(g) hereof, all of Employer's obligations
hereunder, including Employer's obligations to pay Employee the compensation
provided in paragraph 3 hereof, shall immediately cease.





                                       7
<PAGE>   8
       15.    Other Termination by Employer.  In the event Employer terminates
Employee's employment hereunder for any reason other than as provided in
paragraphs 12, 13 or 14, (a) all of Employer's obligations hereunder, including
Employer's obligations to pay Employee the compensation provided in paragraph 3
hereof, shall continue until terminated under paragraph 14 above, and (b)
notwithstanding anything to the contrary contained herein, the provisions of
paragraph 17 hereof shall not apply.

       16.    Disclosure of Information.  Employee acknowledges that, in and as
a result of Employee's employment with Employer, Employee has and will be
making use of, acquiring, developing and/or adding to confidential information
of special and unique value relating to such matters as Employer Companies'
products, trade secrets, systems, procedures, manuals, confidential reports,
customer and supplier lists, and other information, data and displays, whether
or not patented or copyrighted, as well as the nature and type of product sold
by Employer Companies, the identity of Employer Companies' suppliers and
customers, the products and methods used and preferred by Employer Companies'
customers, and the prices paid by such customers (collectively hereinafter
referred to as the "Confidential Information").  As a material inducement to
Employer to enter into this Agreement and to pay to Employee the compensation
referred to in paragraph 3 hereof (as well as any additional benefits referred
to herein), Employee covenants and agrees that Employee and Employee's
partners, agents, representatives, servants, employers, employees and any and
all other persons acting, directly or indirectly, for or with Employee shall
not, at any time during or following the term of Employee's employment
hereunder, directly or indirectly, for any purpose whatsoever, divulge or
disclose any of the Confidential Information which has been obtained by or
disclosed to Employee and shall not at any time during or following the term of
Employee's employment hereunder, directly or indirectly, use, for any purpose
whatsoever, any of the Confidential Information for Employee's benefit or for
any purpose, whether or not beneficial to Employee, except for the purpose of
permitting Employee to perform the services for Employer contemplated by this
Agreement.  Employee further covenants and agrees that all such Confidential
Information shall be the exclusive property of Employer and, upon the
expiration of this Agreement, Employee shall deliver to Employer all
Confidential Information then in the possession, custody or control of Employee
and without regard to the form in which such Confidential Information is stored
or the media for storage for such Confidential Information.

       17.    Covenants Against Competition.  Employee acknowledges that
Employee's services to be rendered hereunder are of a special and unusual
character which have a unique value to Employer, the loss of which cannot
adequately be compensated by damages in an action at law.  In view of the
unique value to Employer of the services of Employee for which Employer has
contracted hereunder,





                                       8
<PAGE>   9
and because of the Confidential Information to be obtained by or disclosed to
Employee, as hereinabove set forth, and as a material inducement to Employer to
enter into this Agreement, and to pay to Employee the compensation referred to
in paragraph 3 hereof, (as well as any additional benefits referred to herein),
Employee covenants and agrees that Employee and Employee's partners, agents,
representatives, servants, employers, employees and any and all other persons
acting, directly or indirectly, for or with Employee  shall not, during the
term of this Agreement and for a period of two (2) years thereafter, within the
continental United States:

              (a)    Solicit in any manner the termination of any of the
       Agreements (the "CNG Agreements") between any of the Employer Companies 
       and any end-user customer ("CNG End-User") or supplier ("CNG Supplier");

              (b)    Prior to or immediately upon termination of any CNG
       Agreement, compete with or bid competitively against any of the Employer
       Companies in order to sell product to any CNG End-User or obtain supply
       or product from the same source of supply provided by any CNG Supplier
       to any of the Employer Companies; or

              (c)    Solicit for employment or employ any person who is then or
       was at any time during the term of this Agreement an employee of
       Employer Companies.

       18.    Reasonableness of Restrictions.  Employee has carefully read and
considered the provisions of paragraphs 16 and 17 hereof and having done so,
agrees that the restrictions set forth in such paragraphs (including, but not
limited to, the time period restriction and the geographical areas of
restriction set forth in paragraphs 16 and 17) are fair and reasonable and are
reasonably required for the protection of the interests of Employer, its
officers, directors and other employees.  Notwithstanding the foregoing, in the
event that any of the provisions of paragraphs 16 or 17 shall be held to be
invalid or unenforceable, the remaining provisions thereof shall nevertheless
continue to be valid and enforceable as though the invalid or unenforceable
parts had not been included therein.  In the event that any provision of
paragraph 16 or 17 relating to time period and/or areas of restriction shall be
declared by a court of competent jurisdiction to exceed the maximum time period
or areas such court deems reasonable and enforceable, such time period and/or
areas of restriction shall be deemed to become and thereafter be the maximum
time period and/or areas which such court deems reasonable and enforceable.

       19.    Equitable Relief; Accounting for Profits.  In the event of a
breach or threatened breach of any of the provisions of paragraphs 16 or 17,
Employer, in addition to and not in limitation of any other rights or remedies
available to Employer at law or in equity, shall be entitled to a permanent
injunction in order to





                                      9
<PAGE>   10
prevent or to restrain any such breach by Employee or by Employee's partners,
agents, representatives, servants, employers, employees and/or any and all
persons, directly or indirectly, acting for or with Employee.  Employee further
covenants and agrees that if Employee shall violate any of Employee's covenants
and agreements pursuant to paragraphs 16 and 17 above, Employer shall be
entitled to an accounting and repayment of all profits, compensations,
commissions, remunerations and/or other benefits which Employee, directly or
indirectly, may realize as a result of, growing out of or in connection with,
any such violation.  Such remedy shall be in addition to and not in limitation
of any injunctive relief or other rights or remedies which Employer is or may
be entitled to at law or in equity or under this Agreement.  In any action
brought by Employer against Employee for the breach of paragraph 16 or 17,
Employer shall be entitled to recover Employer's costs and expenses, including
reasonable attorneys' fees.

       20.    Notices.  Any notice required or permitted to be given under this
Agreement shall be sufficient if in writing, and shall be deemed to have been
given if personally delivered or if deposited in the United States mail, by
certified mail, with proper postage prepaid thereon, addressed as follows:

       If to Employer:      Continental Natural Gas, Inc.

or to such other address as either party may hereafter advise the other by
notice given in accordance with the provisions hereof.

       21.    Waiver of Breach.  The waiver by Employer of a breach of any
provision of this Agreement by Employee shall not operate or be construed as a
waiver of any subsequent breach by Employee.

       22.    Assignment.  Employer may assign this Agreement to any successor

                             STATEMENT OF AGREEMENT

         NOW, THEREFORE, in consideration of the mutual covenants and
agreements herein contained and other good and valuable consideration this day
paid by each party to the other, the receipt and sufficiency of which are
hereby acknowledged, Employer and Employee agree as follows:

         1.      Employment.  Employer hereby agrees to continue the employment
of Employee and Employee hereby agrees to continue to provide Employee's
services to Employer upon the terms and conditions herein stated.

         2.      Term.  Subject to the provisions for termination as

         3.      Compensation.

                 (a)      Salary.  For services rendered by Employee under this
         Agreement, Employer shall pay Employee a salary of One Hundred Fifty
         Thousand Dollars ($150,000.00) per annum, payable in twenty-six (26)
         equal bi-weekly installments.  On
<PAGE>   2
         January 1 of each calendar year during the term hereof, the annual
         salary payable to Employee pursuant to this paragraph 3(a) shall be
         increased by a percentage equal to the percentage increase as of such
         date, if any, in the Official Consumers Price Index published by the
         Bureau of Labor Statistics of the U. S. Department of Labor,
         applicable to the smallest geographic region which includes Tulsa,
         Oklahoma, with reference to the Official Consumers Price Index for
         January 1 of the previous year.

                 (b)      Bonus.  For the calendar year 1997 and for all
         subsequent calendar years during the term of this Agreement, Employer
         shall pay Employee a yearly bonus equal as follows:

                          (i)  If the Adjusted Income for such calendar year is
                 equal to or greater than the Initial Threshold, but less than
                 the Second Threshold, the yearly bonus payable to Employee
                 shall equal the product obtained by multipying (A) $50,000 by
                 (B) a fraction (I) the numerator of which is the amount by
                 which the Adjusted Income for such calendar year exceeds the
                 Initial Threshold and (II) the denominator of which is the
                 difference between the Second Threshold and the Initial
                 Threshold;

                          (ii)  If the Adjusted Income is equal to or greater
                 than the Second Threshold, but less than the Third Threshold,
                 the yearly bonus payable to Employee shall equal $50,000;

                          (iii)  If the Adjusted Income is equal to or greater
                 than the Third Threshold, but less than the Fourth Threshold,
                 the yearly bonus payable to Employee shall equal $100,000; or

                          (iv)  If the Adjusted Income is equal to or greater
                 than the Fourth Threshold, the yearly bonus payable to
                 Employee shall equal $150,000.

         The Thresholds for the 1997 calendar year shall be as follows:

                 Initial Threshold = $4,400,000
                 Second Threshold = $5,500,000
                 Third Threshold = $6,600,000
                 Fourth Threshold = $7,700,000

         For any calendar year subsequent to 1997, the Initial Threshold shall
         be an amount equal to 20% of Average Daily Adjusted Equity for the
         previous calendar year, the Second Threshold will be 25% of such
         Average Daily Adjusted Equity, the Third Threshold will be 30% of such
         Average Daily Adjusted Equity and the Fourth Threshold will be 35% of
         such Average





                                       2
<PAGE>   3
         Daily Adjusted Equity .  As used herein, the term "Adjusted Income"
         shall mean, for the calendar year in question, the income of Employer
         before income taxes plus depreciation, depletion and amortization and
         any other noncash items.  As used herein, the term "Average Daily
         Adjusted Equity" shall mean, for the calendar year in question, the
         average of the Adjusted Equity for the year in question; such Adjusted
         Equity being an amount, determined each day, equal to (A) the
         stockholders' equity of Employer as of the last day of the previous
         calendar year less (B) the then Unutilized IPO Proceeds.  As of any
         day, the then Unutilized IPO Proceeds shall be an amount equal to (I)
         the net proceeds, after all expenses, to Employer raised pursuant to
         the initial public offering ("IPO") consummated by Employer as of the
         effective date of this Agreement less (II) the amount of Employer's
         long-term debt as of such day which has been incurred by Employer
         since the date of the IPO (plus any long-term debt incurred by
         Employer prior to the IPO if incurred in contemplation of the IPO, as
         determined by Employer, in Employer's sole discretion, exercised in
         good faith).

                 Within thirty (30) days after the end of each calendar month,
         Employer shall make a good faith estimate of the Adjusted Income for
         such calendar month and pay Employee the estimated bonus attributable
         thereto).  Within ninety (90) days after the end of each calendar year
         during the term hereof, an accounting of the actual amounts owed to
         Employee pursuant to this paragraph 3(b) shall be conducted by
         Employer and, to the extent of the difference between the aggregate of
         the estimated monthly payments to Employee and the actual amounts owed
         by Employer to Employee, the party owing such amounts shall make
         payment to the other.  Such payment shall be made within five (5) days
         after delivery of the accounting to Employee.  Any payment not paid on
         or before the due date therefor shall bear interest at a varying rate
         of interest per annum equal to the prime lending rate of Bank of
         Oklahoma, N.A., plus one and one-half percent (1-1/2%).

                 If this Agreement becomes effective on any day other than
         January 1, the bonus payable to Employee for the first calendar year
         during which this Agreement is effective shall be prorated.  The bonus
         payable to Employee for the portion of such calendar year from January
         1 through the day prior to the effective date of this Agreement shall
         be paid based upon the terms of the Employment Agreement prior to its
         amendment and restatement hereunder.  The bonus which would have been
         paid under such Employment Agreement prior to its amendment and
         restatement hereunder shall be computed for the entire calendar year
         and then multiplied by a fraction, the numerator of which is the
         number of days of such calendar year prior to the effective date of
         this Agreement and the denominator of which is the number of days in
         such entire calendar year.  The





                                       3
<PAGE>   4
         bonus payable to Employee for the remaining portion of such calendar
         year shall be paid based upon the terms described in this paragraph
         3(b), prorated in the same manner as described in the preceding
         sentence (using the number of remaining days in such calendar year as
         the numerator).
                          
                 (c)      Determination of Adjusted Income and Average Daily
         Adjusted Equity.  The Adjusted Income and Average Daily Adjusted
         Equity shall be determined by the certified public accountant or
         accounting firm (the "CPA") which normally audits the books of
         Employer.  Such determinations shall be made using generally accepted
         accounting principles, consistently applied and consistent with past
         practices of Employer.  Such determinations shall be binding on all
         parties and conclusive in all respects; provided, however, Employee
         shall have the right to audit the determinations.  If Employee's audit
         reveals inconsistencies in the determination by the CPA resulting in
         an error in the amount payable hereunder for any twelve-month period
         in excess of five percent (5%), Employer shall bear the cost of
         Employee's audit.  Otherwise, Employee's audit shall be Employee's
         expense.  After any such audit, once the correct amount owed is
         determined, the party owing the other shall pay the amount owed upon
         demand.

                 (d)      Automobile Allowance.  Employer shall also pay
         Employee at the same times Employee is paid salary pursuant to
         paragraph 3(a) above, Four Hundred Dollars ($400.00) per month during
         the term of this Agreement as an automobile allowance.  In
         consideration thereof and as a result of the nature of the services to
         be performed by Employee, Employee shall keep an automobile available
         and in working condition so that Employee can adequately perform the
         services required to be performed by Employee hereunder.

                 (e)      Additional Compensation.  The compensation agreed to
         be paid to Employee by Employer in this paragraph 3 shall not operate
         in any manner as a limitation of any type upon or as a direction,
         express or implied, against the exercise by the Board (the "Board") of
         Directors of Employer of its power, authority and discretion to grant
         additional bonuses and/or fees or other additional direct or indirect
         benefits or compensation to or on behalf of Employee if, in the
         business judgment of the Board, such action is merited and in the best
         interest of Employer.

                 (f)      Withholding.  The salary and any other compensation
         paid to Employee shall be subject to any and all such payroll and
         withholding deductions as are required by the laws of any
         jurisdiction, federal, state or local, with taxing authority with
         respect to such salary and other compensation.

                 (g)      Payments after Termination.  Notwithstanding any
         other provision of this Agreement to the contrary, except as provided
         in paragraph 13 hereof, any payment required pursuant to this
         paragraph 3 attributable to any period of time occurring during the
         term of this Agreement shall be made when due despite the fact that
         such payment is due after termination of this Agreement.

         4.      Duties.  To the best of Employee's ability, using reasonable
and prudent judgment and care, Employee shall render such services and perform
such duties as are customary for a Vice-President of Operations in the industry
and as may be requested by Employer from time to time.

         5.      Extent of Services.  Employee shall devote such time and
energy to the furtherance of Employer's business as shall be determined by the
Board.  During the term of this Agreement, Employee shall not, directly or
indirectly, alone or as a member of any business entity, or as an officer,
director or stockholder of any corporation, be engaged in or concerned with any
other commercial or business duties or pursuits which would require such
substantial services on the part of Employee that Employee, in Employer's sole
opinion, would be unable to perform the services required to be performed by
Employee hereby.

         6.      Working Facilities and Staff.  Employee shall be furnished
with such facilities, staff and services as are suitable to Employee's position
and adequate for the performance of Employee's duties.

         7.      Expenses.  Employer will reimburse Employee for all such
expenses which Employer, in Employer's sole discretion, deems are reasonably
incurred for promoting the business of Employer, upon the presentation by
Employee, from time to time, of an itemized account of such expenditures.

         8.      Vacations.  During the term of this Agreement, Employee shall
be entitled, during each year of employment with Employer, to a vacation in
accordance with the established company policy of Employer, during which time
Employee's compensation hereunder shall be paid in full.

         9.      Insurance.  During the term of this Agreement, Employer shall
provide to Employee, and pay all premiums for, major medical insurance with
coverage for Employee and Employee's immediate family on terms no less
favorable than is currently provided.

         10.     Pension and Profit-sharing Plan.  During the term of this
Agreement, to the extent it is financially reasonable as determined by the
Board, Employer shall maintain in effect any pension and profit-sharing plans
maintained by Employer as of the date hereof





                                       5
<PAGE>   6
and Employee shall be entitled to participate in such plans on a
non-discriminatory basis.

         11.     Memberships.  During the term of this Agreement, Employer
agrees to pay, on behalf of Employee, up to Three Thousand Dollars ($3,000.00)
per year for dues and/or fees for club memberships, dinner clubs and/or
professional organizations.

         12.     Disability and Death.  If Employee is unable to perform
Employee's services by reason of illness or incapacity for a period of more
than ninety (90) consecutive days, the compensation otherwise payable to
Employee during the continued period of such illness or incapacity shall be
reduced by fifty percent (50%).  Employee's full compensation shall be
reinstated upon Employee's return to employment and the discharge of Employee's
full duties hereunder.  Notwithstanding anything herein to the contrary,
Employer may terminate this Agreement at any time after Employee shall be
absent from Employee's employment, for whatever cause, for a continuous period
of more than sixty (60) consecutive days, in which event, subject to paragraph
3(g) hereof, all obligations of the Employer hereunder, including Employer's
obligations to pay Employee the compensation provided in paragraph 3 hereof,
shall immediately cease upon any such termination.  In no event, however, shall
any provision of this paragraph 12 be interpreted to limit or restrict
Employee's rights to participate in and receive benefits under the existing
Employer disability plan(s).  Subject to paragraph 3(g) hereof, all of
Employer's obligations hereunder, including Employer's obligations to pay
Employee the compensation provided in paragraph 3 hereof, shall cease
immediately upon Employee's death.  The determination of all periods of time
under this paragraph 12 shall be calculated by including (and counting)
weekends which occur within the applicable period but excluding days of sick
leave, vacation, holidays and other days off, if any, allowed pursuant to
established company policy of Employer.

         13.     Termination for Cause.  Employer may terminate Employee's
employment under this Agreement upon (10) days' notice to Employee after the
occurrence of any of the following events ("Cause Events") unless such events
were caused at the direction of Employer:

                 (a)      Any failure by Employee to faithfully perform the
         covenants and agreements of Employee herein stated;

                 (b)      Willful, gross misconduct by Employee in connection
         with the performance of the covenants and agreements of Employee
         herein stated;

                 (c)      If Employee violates any law, rule or regulation
         which violation materially adversely affects Employer or any of
         Employer's subsidiaries or other affiliates (collectively hereinafter
         referred to as the "Employer Companies");





                                       6
<PAGE>   7
                 (d)      If Employee violates any of the provisions of
         paragraphs 16 or 17;

                 (e)       If Employee converts any property of Employer 
         Companies;

                 (f)      If Employee is convicted of any felony which
         materially adversely affects Employer Companies or the ability of
         Employee to perform Employee's duties hereunder; or

                 (g)      If Employee is convicted of any lesser crime or
         offense involving property or business of Employer Companies.

In the event of a dispute as to whether a Cause Event has occurred, upon the
request of Employer or Employee, such dispute shall be resolved pursuant to the
expedited procedures of the commercial arbitration rules of the American
Arbitration Association regardless of the amount in controversy, with each
party to bear its own arbitration costs and expenses.  The parties stipulate
that the hearing locale for any such arbitration proceeding will be Tulsa,
Oklahoma.  Judgment upon the award rendered as a result of such arbitration may
be entered in any court having jurisdiction thereof.  The parties further
stipulate that the provisions hereof shall be a complete defense to any suit,
action or proceeding instituted in any federal, state or local court or before
any administrative tribunal with respect to any controversy or dispute arising
out of or relating to whether a Cause Event has occurred.  Upon termination of
Employee's employment under this Agreement as a result of a Cause Event, all of
Employer's obligations hereunder, including Employer's obligations to pay
Employee the compensation provided in paragraph 3 hereof (whether or not then
accrued), shall immediately cease.  Nothing contained herein shall be construed
as limiting in any manner any of the rights or remedies available to Employer
pursuant to this agreement or otherwise with respect to such Cause Event.

         14.     Expiration of Term.  In the event this Agreement is terminated
due to expiration of the term of this Agreement as set forth in paragraph 2
hereof, subject to paragraph 3(g) hereof, all of Employer's obligations
hereunder, including Employer's obligations to pay Employee the compensation
provided in paragraph 3 hereof, shall immediately cease.

         15.     Other Termination by Employer.  In the event Employer
terminates Employee's employment hereunder for any reason other than as
provided in paragraphs 12, 13 or 14, (a) all of Employer's obligations
hereunder, including Employer's obligations to pay Employee the compensation
provided in paragraph 3 hereof, shall continue until terminated under paragraph
14 above, and (b) notwithstanding anything to the contrary contained herein,
the provisions of paragraph 17 hereof shall not apply.

         16.     Disclosure of Information.  Employee acknowledges that, in and
as a result of Employee's employment with Employer, Employee has and will be
making use of, acquiring, developing and/or adding to confidential information
of special and unique value relating to such matters as Employer Companies'
products, trade secrets, systems, procedures, manuals, confidential reports,
customer and supplier lists, and other information, data and displays, whether
or not patented or copyrighted, as well as the nature and type of product sold
by Employer Companies, the identity of Employer Companies' suppliers and
customers, the products and methods used and preferred by Employer Companies'
customers, and the prices paid by such customers (collectively hereinafter
referred to as the "Confidential Information").  As a material inducement to
Employer to enter into this Agreement and to pay to Employee the compensation
referred to in paragraph 3 hereof (as well as any additional benefits referred
to herein), Employee covenants and agrees that Employee and Employee's
partners, agents, representatives, servants, employers, employees and any and
all other persons acting, directly or indirectly, for or with Employee shall
not, at any time during or following the term of Employee's employment
hereunder, directly or indirectly, for any purpose whatsoever, divulge or
disclose any of the Confidential Information which has been obtained by or
disclosed to Employee and shall not at any time during or following the term of
Employee's employment hereunder, directly or indirectly, use, for any purpose
whatsoever, any of the Confidential Information for Employee's benefit or for
any purpose, whether or not beneficial to Employee, except for the purpose of
permitting Employee to perform the services for Employer contemplated by this
Agreement.  Employee further covenants and agrees that all such Confidential
Information shall be the exclusive property of Employer and, upon the
expiration of this Agreement, Employee shall deliver to Employer all
Confidential Information then in the possession, custody or control of Employee
and without regard to the form in which such Confidential Information is stored
or the media for storage for such Confidential Information.

         17.     Covenants Against Competition.  Employee acknowledges that
Employee's services to be rendered hereunder are of a special and unusual
character which have a unique value to Employer, the loss of which cannot
adequately be compensated by damages in an action at law.  In view of the
unique value to Employer of the services of Employee for which Employer has
contracted hereunder, and because of the Confidential Information to be
obtained by or disclosed to Employee, as hereinabove set forth, and as a
material inducement to Employer to enter into this Agreement, and to pay to
Employee the compensation referred to in paragraph 3 hereof, (as well as any
additional benefits referred to herein), Employee covenants and agrees that
Employee and Employee's partners, agents, representatives, servants, employers,
employees and any and all other persons acting, directly or indirectly, for or
with Employee





                                       8
<PAGE>   9
shall not, during the term of this Agreement and for a period of two (2) years
thereafter, within the continental United States:

                 (a)      Solicit in any manner the termination of any of the
         Agreements (the "CNG Agreements") between any of the Employer
         Companies and any end-user customer ("CNG End-User") or supplier ("CNG
         Supplier");

                 (b)      Prior to or immediately upon termination of any CNG
         Agreement, compete with or bid competitively against any of the
         Employer Companies in order to sell product to any CNG End-User or
         obtain supply or product from the same source of supply provided by
         any CNG Supplier to any of the Employer Companies; or

                 (c)      Solicit for employment or employ any person who is
         then or was at any time during the term of this Agreement an employee
         of Employer Companies.

         18.     Reasonableness of Restrictions.  Employee has carefully read
and considered the provisions of paragraphs 16 and 17 hereof and having done
so, agrees that the restrictions set forth in such paragraphs (including, but
not limited to, the time period restriction and the geographical areas of
restriction set forth in paragraphs 16 and 17) are fair and reasonable and are
reasonably required for the protection of the interests of Employer, its
officers, directors and other employees.  Notwithstanding the foregoing, in the
event that any of the provisions of paragraphs 16 or 17 shall be held to be
invalid or unenforceable, the remaining provisions thereof shall nevertheless
continue to be valid and enforceable as though the invalid or unenforceable
parts had not been included therein.  In the event that any provision of
paragraph 16 or 17 relating to time period and/or areas of restriction shall be
declared by a court of competent jurisdiction to exceed the maximum time period
or areas such court deems reasonable and enforceable, such time period and/or
areas of restriction shall be deemed to become and thereafter be the maximum
time period and/or areas which such court deems reasonable and enforceable.

         19.     Equitable Relief; Accounting for Profits.  In the event of a
breach or threatened breach of any of the provisions of paragraphs 16 or 17,
Employer, in addition to and not in limitation of any other rights or remedies
available to Employer at law or in equity, shall be entitled to a permanent
injunction in order to prevent or to restrain any such breach by Employee or by
Employee's partners, agents, representatives, servants, employers, employees
and/or any and all persons, directly or indirectly, acting for or with
Employee.  Employee further covenants and agrees that if Employee shall violate
any of Employee's covenants and agreements pursuant to paragraphs 16 and 17
above, Employer shall be entitled to an accounting and repayment of all
profits, compensations, commissions, remunerations and/or other benefits which
Employee,





                                       9
<PAGE>   10
directly or indirectly, may realize as a result of, growing out of or in
connection with, any such violation.  Such remedy shall be in addition to and
not in limitation of any injunctive relief or other rights or remedies which
Employer is or may be entitled to at law or in equity or under this Agreement.
In any action brought by Employer against Employee for the breach of paragraph
16 or 17, Employer shall be entitled to recover Employer's costs and expenses,
including reasonable attorneys' fees.

         20.     Notices.  Any notice required or permitted to be given under
this Agreement shall be sufficient if in writing, and shall be deemed to have

or to such other address as either party may hereafter advise the other by
notice given in accordance with the provisions hereof.

         21.     Waiver of Breach.  The waiver by Employer of a breach of any
provision of this Agreement by Employee shall not operate or be construed as a
waiver of any subsequent breach by Employee.

         22.     Assignment.  Employer may assign this Agreement to any

waive any objection to the laying of venue of any action, suit or proceeding
arising out of this Agreement or the transactions contemplated hereby in the
Agreed Courts and hereby further irrevocably and unconditionally waive and
agree not to plead or claim that any such action, suit or proceeding brought in
any of the Agreed Courts has been brought in an inconvenient forum.

         25.     Entire Agreement.  This instrument contains the entire
Agreement of the parties pertaining to Employee's employment by Employer,
superseding all other agreements (including, without limitation, the March 27,

pursuant to the Prior Employment Agreements or otherwise.

         26.     Severability.  The provisions of this Agreement shall be
deemed severable, and the invalidity or unenforceability of any one or more of
the provisions hereof shall not affect the validity and enforceability of the
other provisions hereof.

Agreement shall be construed simply according to its fair meaning and not
strictly for or against any party.

                             STATEMENT OF AGREEMENT

         NOW, THEREFORE, in consideration of the mutual covenants and
agreements herein contained and other good and valuable consideration this day
paid by each party to the other, the receipt and sufficiency of which are
hereby acknowledged, Employer and Employee agree as follows:

         1.      Employment.  Employer hereby agrees to continue the employment
of Employee and Employee hereby agrees to continue to provide Employee's
services to Employer upon the terms and conditions herein stated.

         2.      Term.  Subject to the provisions for termination as
hereinafter provided, the term of this Agreement shall begin as of the date
hereof, and shall terminate on December 31, 1999.

         3.      Compensation.

                 (a)      Salary.  For services rendered by Employee under this
         Agreement, Employer shall pay Employee a salary of One Hundred Fifty
         Thousand Dollars ($150,000.00) per annum, payable in twenty-six (26)
         equal bi- weekly installments.  On
<PAGE>   2
         January 1 of each calendar year during the term hereof, the annual
         salary payable to Employee pursuant to this paragraph 3(a) shall be
         increased by a percentage equal to the percentage increase as of such
         date, if any, in the Official Consumers Price Index published by the
         Bureau of Labor Statistics of the U. S. Department of Labor,
         applicable to the smallest geographic region which includes Tulsa,
         Oklahoma, with reference to the Official Consumers Price Index for
         January 1 of the previous year.

                 (b)      Commissions.  Employer shall pay Employee a
         commission equal to the sum of one and one-half percent (1.5%) of the
         "Commission Base," as hereinafter defined, for each twelve-month
         period during the term of this Agreement.  As used herein, the term
         "Commission Base" shall mean the total dollar amount of sales of
         energy related products by the Employer for the applicable
         twelve-month period, less the cost of the product, transportation,
         wet/dry conversions, fuel usage, line loss and commissions paid to
         parties not employed by Employer.

                          (i)     Notwithstanding the foregoing provisions of
                 this paragraph 3(b), in the event there is no "Adjusted
                 Income," as hereinafter defined, of Employer for any
                 twelve-month period, no commission shall be payable to
                 Employee for such period or any subsequent period until such
                 Adjusted Income is positive after restoration in full of any
                 deficit in the computation of Net Income for all previous
                 twelve-month periods.

                          (ii)    Payments to Employee pursuant to this
                 paragraph 3(b) shall be based on the estimated Commission Base
                 for each calendar month.  Payment to Employee for any
                 particular calendar month shall be made to Employee, in cash,
                 on or before the thirty-sixth (36th) day after the end of such
                 calendar month.  Within one hundred twenty (120) days after
                 the end of each calendar month, an accounting of the actual
                 amounts owed to Employee pursuant to this paragraph 3(b) shall
                 be conducted by Employer and, to the extent of the difference
                 between the estimated payments to Employee and the actual
                 amounts owed by Employer to Employee, Employer shall make
                 additional payments to Employee or Employee shall reimburse
                 Employer, as the case may be.  Such additional payments or
                 reimbursements shall be made within five (5) days after
                 delivery of the accounting to Employee.  Any payment not paid
                 on or before the due date therefor shall bear interest at a
                 varying rate of interest per annum equal to the prime lending
                 rate of Bank of Oklahoma, N.A., plus one and one-half percent
                 (1.5%).

                 (c)      Bonus.  For the calendar year 1997 and for all
         subsequent calendar years during the term of this Agreement, Employer
         shall pay Employee a yearly bonus equal as follows:

                          (i)  If the Adjusted Income for such calendar year is
                 equal to or greater than the Initial Threshold, but less than
                 the Second Threshold, the yearly bonus payable to Employee
                 shall equal the product obtained by multipying (A) $50,000 by
                 (B) a fraction (I) the numerator of which is the amount by
                 which the Adjusted Income for such calendar year exceeds the
                 Initial Threshold and (II) the denominator of which is the
                 difference between the Second Threshold and the Initial
                 Threshold;

                          (ii)  If the Adjusted Income is equal to or greater
                 than the Second Threshold, but less than the Third Threshold,
                 the yearly bonus payable to Employee shall equal $50,000;

                          (iii)  If the Adjusted Income is equal to or greater
                 than the Third Threshold, but less than the Fourth Threshold,
                 the yearly bonus payable to Employee shall equal $100,000; or

                          (iv)  If the Adjusted Income is equal to or greater
                 than the Fourth Threshold, the yearly bonus payable to
                 Employee shall equal $150,000.

         The Thresholds for the 1997 calendar year shall be as follows:

                 Initial Threshold = $4,400,000
                 Second Threshold =  $5,500,000
                 Third Threshold =   $6,600,000
                 Fourth Threshold =  $7,700,000

         For any calendar year subsequent to 1997, the Initial Threshold shall
         be an amount equal to 20% of Average Daily Adjusted Equity for the
         previous calendar year, the Second Threshold will be 25% of such
         Average Daily Adjusted Equity, the Third Threshold will be 30% of such
         Average Daily Adjusted Equity and the Fourth Threshold will be 35% of
         such Average Daily Adjusted Equity .  As used herein, the term
         "Adjusted Income" shall mean, for the calendar year in question, the
         income of Employer before income taxes plus depreciation, depletion
         and amortization and any other noncash items.  As used herein, the
         term "Average Daily Adjusted Equity" shall mean, for the calendar year
         in question, the average of the Adjusted Equity for the year in
         question; such Adjusted Equity being an amount, determined each day,
         equal to (A) the stockholders' equity of Employer as of the last day
         of the previous calendar year less (B) the then Unutilized IPO





                                       3
<PAGE>   4
         Proceeds.  As of any day, the then Unutilized IPO Proceeds shall be an
         amount equal to (I) the net proceeds, after all expenses, to Employer
         raised pursuant to the initial public offering ("IPO") consummated by
         Employer as of the effective date of this Agreement less (II) the
         amount of Employer's long-term debt as of such day which has been
         incurred by Employer since the date of the IPO (plus any long-term
         debt incurred by Employer prior to the IPO if incurred in
         contemplation of the IPO, as determined by Employer, in Employer's
         sole discretion, exercised in good faith).

                 Within thirty (30) days after the end of each calendar month,
         Employer shall make a good faith estimate of the Adjusted Income for
         such calendar month and pay Employee the estimated bonus attributable
         thereto).  Within ninety (90) days after the end of each calendar year
         during the term hereof, an accounting of the actual amounts owed to
         Employee pursuant to this paragraph 3(c) shall be conducted by
         Employer and, to the extent of the difference between the aggregate of
         the estimated monthly payments to Employee and the actual amounts owed
         by Employer to Employee, the party owing such amounts shall make
         payment to the other.  Such payment shall be made within five (5) days
         after delivery of the accounting to Employee.  Any payment not paid on
         or before the due date therefor shall bear interest at a varying rate
         of interest per annum equal to the prime lending rate of Bank of
         Oklahoma, N.A., plus one and one-half percent (1-1/2%).

                 If this Agreement becomes effective on any day other than
         January 1, the bonus payable to Employee for the first calendar year
         during which this Agreement is effective shall be prorated.  The bonus
         payable to Employee for the portion of such calendar year from January
         1 through the day prior to the effective date of this Agreement shall
         be paid based upon the terms of the Employment Agreement prior to its
         amendment and restatement hereunder.  The bonus which would have been
         paid under such Employment Agreement prior to its amendment and
         restatement hereunder shall be computed for the entire calendar year
         and then multiplied by a fraction, the numerator of which is the
         number of days of such calendar year prior to the effective date of
         this Agreement and the denominator of which is the number of days in
         such entire calendar year.  The bonus payable to Employee for the
         remaining portion of such calendar year shall be paid based upon the
         terms described in this paragraph 3(c), prorated in the same manner as
         described in the preceding sentence (using the number of remaining
         days in such calendar year as the numerator).

                 (d) Determination of Adjusted Income and Average Daily
         Adjusted Equity.  The Adjusted Income and Average Daily Adjusted
         Equity shall be determined by the certified public accountant or
         accounting firm (the "CPA") which normally





                                       4
<PAGE>   5
         audits the books of Employer.  Such determinations shall be made using
         generally accepted accounting principles, consistently applied and
         consistent with past practices of Employer.  Such determinations shall
         be binding on all parties and conclusive in all respects; provided,
         however, Employee shall have the right to audit the determinations.
         If Employee's audit reveals inconsistencies in the determination by
         the CPA resulting in an error in the amount payable hereunder for any
         twelve-month period in excess of five percent (5%), Employer shall
         bear the cost of Employee's audit.  Otherwise, Employee's audit shall
         be Employee's expense.  After any such audit, once the correct amount
         owed is determined, the party owing the other shall pay the amount
         owed upon demand.

                 (e)      Automobile Allowance.  Employer shall also pay
         Employee at the same times Employee is paid salary pursuant to
         paragraph 3(a) above, Four Hundred Dollars ($400.00) per month during
         the term of this Agreement as an automobile allowance.  In
         consideration thereof and as a result of the nature of the services to
         be performed by Employee, Employee shall keep an automobile available
         and in working condition so that Employee can adequately perform the
         services required to be performed by Employee hereunder.

                 (f)      Additional Compensation.  The compensation agreed to
         be paid to Employee by Employer in this paragraph 3 shall not operate
         in any manner as a limitation of any type upon or as a direction,
         express or implied, against the exercise by the Board (the "Board") of
         Directors of Employer of its power, authority and discretion to grant
         additional bonuses and/or fees or other additional direct or indirect
         benefits or compensation to or on behalf of Employee if, in the
         business judgment of the Board, such action is merited and in the best
         interest of Employer.

                 (g)      Withholding.  The salary and any other compensation
         paid to Employee shall be subject to any and all such payroll and
         withholding deductions as are required by the laws of any
         jurisdiction, federal, state or local, with taxing authority with
         respect to such salary and other compensation.

                 (h)      Payments after Termination.  Notwithstanding any
         other provision of this Agreement to the contrary, except as provided
         in paragraph 13 hereof, any payment required pursuant to this
         paragraph 3 attributable to any period of time occurring during the
         term of this Agreement shall be made when due despite the fact that
         such payment is due after termination of this Agreement.

         4.      Duties.  To the best of Employee's ability, using reasonable
and prudent judgment and care, Employee shall render





                                       5
<PAGE>   6
such services and perform such duties as are customary for a Vice-President of
Marketing in the industry and as may be requested by Employer from time to
time.

         5.      Extent of Services.  Employee shall devote such time and
energy to the furtherance of Employer's business as shall be determined by the
Board.  During the term of this Agreement, Employee shall not, directly or
indirectly, alone or as a member of any business entity, or as an officer,
director or stockholder of any corporation, be engaged in or concerned with any
other commercial or business duties or pursuits which would require such
substantial services on the part of Employee that Employee, in Employer's sole
opinion, would be unable to perform the services required to be performed by
Employee hereby.

         6.      Working Facilities and Staff.  Employee shall be furnished
with such facilities, staff and services as are suitable to Employee's position
and adequate for the performance of Employee's duties.

         7.      Expenses.  Employer will reimburse Employee for all such
expenses which Employer, in Employer's sole discretion, deems are reasonably
incurred for promoting the business of Employer, upon the presentation by
Employee, from time to time, of an itemized account of such expenditures.

         8.      Vacations.  During the term of this Agreement, Employee shall
be entitled, during each year of employment with Employer, to a vacation in
accordance with the established company policy of Employer, during which time
Employee's compensation hereunder shall be paid in full.

         9.      Insurance.  During the term of this Agreement, Employer shall
provide to Employee, and pay all premiums for, major medical insurance with
coverage for Employee and Employee's immediate family on terms no less
favorable than is currently provided.

         10.     Pension and Profit-sharing Plan.  During the term of this
Agreement, to the extent it is financially reasonable as determined by the
Board, Employer shall maintain in effect any pension and profit-sharing plans
maintained by Employer as of the date hereof and Employee shall be entitled to
participate in such plans on a non-discriminatory basis.

         11.     Memberships.  During the term of this Agreement, Employer
shall maintain its membership at The Golf Club of Oklahoma and Employee shall
be designated as the exclusive user thereof, entitled to enjoy all of the
rights and privileges pertaining thereto.  In addition, Employer agrees to pay,
on behalf of Employee, up to Three Thousand Dollars ($3,000.00) per year for
dues and/or fees for club memberships, dinner clubs and/or professional
organizations.

         12.     Disability and Death.  If Employee is unable to perform
Employee's services by reason of illness or incapacity for a period of more
than ninety (90) consecutive days, the compensation otherwise payable to
Employee during the continued period of such illness or incapacity shall be
reduced by fifty percent (50%).  Employee's full compensation shall be
reinstated upon Employee's return to employment and the discharge of Employee's
full duties hereunder.  Notwithstanding anything herein to the contrary,
Employer may terminate this Agreement at any time after Employee shall be
absent from Employee's employment, for whatever cause, for a continuous period
of more than sixty (60) consecutive days, in which event, subject to paragraph
3(h) hereof, all obligations of the Employer hereunder, including Employer's
obligations to pay Employee the compensation provided in paragraph 3 hereof,
shall immediately cease upon any such termination.  In no event, however, shall
any provision of this paragraph 12 be interpreted to limit or restrict
Employee's rights to participate in and receive benefits under the existing
Employer disability plan(s).  Subject to paragraph 3(h) hereof, all of
Employer's obligations hereunder, including Employer's obligations to pay
Employee the compensation provided in paragraph 3 hereof, shall cease
immediately upon Employee's death.  The determination of all periods of time
under this paragraph 12 shall be calculated by including (and counting)
weekends which occur within the applicable period but excluding days of sick
leave, vacation, holidays and other days off, if any, allowed pursuant to
established company policy of Employer.

         13.     Termination for Cause.  Employer may terminate Employee's
employment under this Agreement upon (10) days' notice to Employee after the
occurrence of any of the following events ("Cause Events") unless such events
were caused at the direction of Employer:

                 (a)      Any failure by Employee to faithfully perform the
         covenants and agreements of Employee herein stated;

                 (b)      Willful, gross misconduct by Employee in connection
         with the performance of the covenants and agreements of Employee
         herein stated;

                 (c)      If Employee violates any law, rule or regulation
         which violation materially adversely affects Employer or any of
         Employer's subsidiaries or other affiliates (collectively hereinafter
         referred to as the "Employer Companies");

                 (d)      If Employee violates any of the provisions of
         paragraphs 16 or 17;

                 (e)  If Employee converts any property of Employer Companies;





                                       7
<PAGE>   8
                 (f)      If Employee is convicted of any felony which
         materially adversely affects Employer Companies or the ability of
         Employee to perform Employee's duties hereunder; or

                 (g)      If Employee is convicted of any lesser crime or
         offense involving property or business of Employer Companies.

In the event of a dispute as to whether a Cause Event has occurred, upon the
request of Employer or Employee, such dispute shall be resolved pursuant to the
expedited procedures of the commercial arbitration rules of the American
Arbitration Association regardless of the amount in controversy, with each
party to bear its own arbitration costs and expenses.  The parties stipulate
that the hearing locale for any such arbitration proceeding will be Tulsa,
Oklahoma.  Judgment upon the award rendered as a result of such arbitration may
be entered in any court having jurisdiction thereof.  The parties further
stipulate that the provisions hereof shall be a complete defense to any suit,
action or proceeding instituted in any federal, state or local court or before
any administrative tribunal with respect to any controversy or dispute arising
out of or relating to whether a Cause Event has occurred.  Upon termination of
Employee's employment under this Agreement as a result of a Cause Event, all of
Employer's obligations hereunder, including Employer's obligations to pay
Employee the compensation provided in paragraph 3 hereof (whether or not then
accrued), shall immediately cease.  Nothing contained herein shall be construed
as limiting in any manner any of the rights or remedies available to Employer
pursuant to this agreement or otherwise with respect to such Cause Event.

         14.     Expiration of Term.  In the event this Agreement is terminated
due to expiration of the term of this Agreement as set forth in paragraph 2
hereof, subject to paragraph 3(h) hereof, all of Employer's obligations
hereunder, including Employer's obligations to pay Employee the compensation
provided in paragraph 3 hereof, shall immediately cease.

         15.     Other Termination by Employer.  In the event Employer
terminates Employee's employment hereunder for any reason other than as
provided in paragraphs 12, 13 or 14, (a) all of Employer's obligations
hereunder, including Employer's obligations to pay Employee the compensation
provided in paragraph 3 hereof, shall continue until terminated under paragraph
14 above, and (b) notwithstanding anything to the contrary contained herein,
the provisions of paragraph 17 hereof shall not apply.

         16.     Disclosure of Information.  Employee acknowledges that, in and
as a result of Employee's employment with Employer, Employee has and will be
making use of, acquiring, developing and/or adding to confidential information
of special and unique value relating to such matters as Employer Companies'
products, trade secrets, systems, procedures, manuals, confidential reports,
customer and





                                       8
<PAGE>   9
supplier lists, and other information, data and displays, whether or not
patented or copyrighted, as well as the nature and type of product sold by
Employer Companies, the identity of Employer Companies' suppliers and
customers, the products and methods used and preferred by Employer Companies'
customers, and the prices paid by such customers (collectively hereinafter
referred to as the "Confidential Information").  As a material inducement to
Employer to enter into this Agreement and to pay to Employee the compensation
referred to in paragraph 3 hereof (as well as any additional benefits referred
to herein), Employee covenants and agrees that Employee and Employee's
partners, agents, representatives, servants, employers, employees and any and
all other persons acting, directly or indirectly, for or with Employee shall
not, at any time during or following the term of Employee's employment
hereunder, directly or indirectly, for any purpose whatsoever, divulge or
disclose any of the Confidential Information which has been obtained by or
disclosed to Employee and shall not at any time during or following the term of
Employee's employment hereunder, directly or indirectly, use, for any purpose
whatsoever, any of the Confidential Information for Employee's benefit or for
any purpose, whether or not beneficial to Employee, except for the purpose of
permitting Employee to perform the services for Employer contemplated by this
Agreement.  Employee further covenants and agrees that all such Confidential
Information shall be the exclusive property of Employer and, upon the
expiration of this Agreement, Employee shall deliver to Employer all
Confidential Information then in the possession, custody or control of Employee
and without regard to the form in which such Confidential Information is stored
or the media for storage for such Confidential Information.

         17.     Covenants Against Competition.  Employee acknowledges that
Employee's services to be rendered hereunder are of a special and unusual
character which have a unique value to Employer, the loss of which cannot
adequately be compensated by damages in an action at law.  In view of the
unique value to Employer of the services of Employee for which Employer has
contracted hereunder, and because of the Confidential Information to be
obtained by or disclosed to Employee, as hereinabove set forth, and as a
material inducement to Employer to enter into this Agreement, and to pay to
Employee the compensation referred to in paragraph 3 hereof, (as well as any
additional benefits referred to herein), Employee covenants and agrees that
Employee and Employee's partners, agents, representatives, servants, employers,
employees and any and all other persons acting, directly or indirectly, for or
with Employee  shall not, during the term of this Agreement and for a period of
two (2) years thereafter, within the continental United States:

                 (a)      Solicit in any manner the termination of any of the
         Agreements (the "CNG Agreements") between any of the Employer
         Companies and any end-user customer ("CNG End-User") or supplier ("CNG
         Supplier");





                                       9
<PAGE>   10
                 (b)      Prior to or immediately upon termination of any CNG
         Agreement, compete with or bid competitively against any of the
         Employer Companies in order to sell product to any CNG End-User or
         obtain supply or product from the same source of supply provided by
         any CNG Supplier to any of the Employer Companies; or

                 (c)      Solicit for employment or employ any person who is
         then or was at any time during the term of this Agreement an employee
         of Employer Companies.

         18.     Reasonableness of Restrictions.  Employee has carefully read
and considered the provisions of paragraphs 16 and 17 hereof and having done
so, agrees that the restrictions set forth in such paragraphs (including, but
not limited to, the time period restriction and the geographical areas of
restriction set forth in paragraphs 16 and 17) are fair and reasonable and are
reasonably required for the protection of the interests of Employer, its
officers, directors and other employees.  Notwithstanding the foregoing, in the
event that any of the provisions of paragraphs 16 or 17 shall be held to be
invalid or unenforceable, the remaining provisions thereof shall nevertheless
continue to be valid and enforceable as though the invalid or unenforceable
parts had not been included therein.  In the event that any provision of
paragraph 16 or 17 relating to time period and/or areas of restriction shall be
declared by a court of competent jurisdiction to exceed the maximum time period
or areas such court deems reasonable and enforceable, such time period and/or
areas of restriction shall be deemed to become and thereafter be the maximum
time period and/or areas which such court deems reasonable and enforceable.

         19.     Equitable Relief; Accounting for Profits.  In the event of a
breach or threatened breach of any of the provisions of paragraphs 16 or 17,
Employer, in addition to and not in limitation of any other rights or remedies
available to Employer at law or in equity, shall be entitled to a permanent
injunction in order to prevent or to restrain any such breach by Employee or by
Employee's partners, agents, representatives, servants, employers, employees
and/or any and all persons, directly or indirectly, acting for or with
Employee.  Employee further covenants and agrees that if Employee shall violate
any of Employee's covenants and agreements pursuant to paragraphs 16 and 17
above, Employer shall be entitled to an accounting and repayment of all
profits, compensations, commissions, remunerations and/or other benefits which
Employee, directly or indirectly, may realize as a result of, growing out of or
in connection with, any such violation.  Such remedy shall be in addition to
and not in limitation of any injunctive relief or other rights or remedies
which Employer is or may be entitled to at law or in equity or under this
Agreement.  In any action brought by Employer against Employee for the breach
of paragraph 16 or 17, Employer shall be entitled to recover Employer's costs
and expenses, including reasonable attorneys' fees.

or to such other address as either party may hereafter advise the other by
notice given in accordance with the provisions hereof.

         21.     Waiver of Breach.  The waiver by Employer of a breach of any

waiver of any subsequent breach by Employee.

         22.     Assignment.  Employer may assign this Agreement to any
successor in interest of Employer's business.  The rights and obligations of
the parties under this Agreement shall inure to the benefit of and shall be

however, that Employee may not assign this Agreement without the prior written
consent of Employer.

         23.     Counterparts.  This Agreement may be executed in two or more

parties hereto irrevocably and unconditionally waive any objection to the
laying of venue of any action, suit or proceeding arising out of this Agreement
or the





                                       11
<PAGE>   12
transactions contemplated hereby in the Agreed Courts and hereby further
irrevocably and unconditionally waive and agree not to plead or claim that any
such action, suit or proceeding brought in any of the Agreed Courts has been
brought in an inconvenient forum.

         25.     Entire Agreement.  This instrument contains the entire
Agreement of the parties pertaining to Employee's employment by Employer,
superseding all other agreements (including, without limitation, the January 1,
1990 Employment Agreement between Employer and Employee, and all amendments,
modifications and supplements thereto) (collectively hereinafter referred to as
the "Prior Employment Agreements") whether oral or written, express or implied.
It may not be changed orally but only by an agreement in writing signed by the
party against whom enforcement of any waiver, change, modification, extension
or discharge is sought.  Further, except as specifically set forth herein,
Employer and Employee do hereby release each other from any and all claims,
known or unknown, fixed or contingent, that either may have against the other
pursuant to the Prior Employment Agreements or otherwise.

         26.     Severability.  The provisions of this Agreement shall be
deemed severable, and the invalidity or unenforceability of any one or more of
the provisions hereof shall not affect the validity and enforceability of the
other provisions hereof.

         27.     Construction.  Every covenant, term and provision of this
Agreement shall be construed simply according to its fair meaning and not
strictly for or against any party.

                                TAX CONSEQUENCES

         Each Participant is urged to consult his or her personal tax advisor
with respect to the tax consequences relating to the grant or the exercise of
any Award under the Plan. However, the following is a summary of general tax
law information relating to awards granted under the Plan.

1.       OPTIONS

         a.  NONQUALIFIED STOCK OPTION ("NQSO")

         This discussion applies to Stock Options which are nonqualified. Under
current law, a Participant receiving an Option does not recognize taxable
income upon the grant of the Option and the Company will not be entitled to a
deduction for federal income tax purposes upon such grant. Upon the exercise of
an Option, ordinary income generally will be recognized by the Participant in
an amount equal to the excess of the fair market value of the Shares acquired
over the exercise price. The Company generally will be entitled to a deduction
for federal income tax purposes in an amount equal to the amount of ordinary
income recognized by the Participant at the time of such recognition, provided
the Company complies with applicable withholding requirements. If the
Participant makes a Section 83(b) election within 30 days after the exercise of
an Option, such Participant will recognize ordinary income upon such exercise.


         b.  INCENTIVE STOCK OPTION ("ISO")

         This discussion applies to Stock Options that are ISOS. Again, a
Participant receiving an ISO does not recognize taxable income upon the grant
of the Option, nor does the Company recognize a deduction for federal income
tax purposes. Upon the exercise of an Incentive Stock Option, the Participant
generally does not recognize taxable income if the exercise is during the term
of the Option either while the Participant is an employee of the Company (or of
a parent or


                                       ii

<PAGE>   5



subsidiary corporation) or within three months thereafter (one year if the
Participant is disabled). If a Participant dies, his or her personal
representative may exercise the Option during its term. Only $100,000 of
aggregate Option Price can be exercised each calendar year by the Participant
in order to avoid recognition of income upon exercise. If the Participant does
not dispose of the shares acquired upon the exercise of an Incentive Option
within two years from the date that the Incentive Option was granted or within
one year after the Incentive Option is exercised, any gain or loss upon
disposition of the shares will be long-term capital gain or loss. If the
Participant disposes of the acquired shares without meeting the statutory
holding period requirements described in the immediately preceding sentence,
the Participant generally will recognize ordinary income in the year of the
disqualifying disposition equal to the difference, if any, between the lesser
of (i) the amount realized on the disposition and (ii) the fair market value of
the shares on the exercise date, and the exercise price. Any remaining gain is
treated as long-term or short-term capital gain depending on whether the shares
have been held for more than one year.

         If the statutory holding period requirements are satisfied, the
Company will not be entitled to a deduction for federal income tax purposes
upon the exercise of an Incentive Option or upon the disposition of shares
acquired upon such exercise. However, if the Participant disposes of the shares
in a disqualifying disposition, the Company generally will be entitled to a
deduction for federal income tax purposes in an amount equal to the amount of
the ordinary income recognized by the Participant at that time, provided that
the Company complies with applicable tax withholding requirements.

2.       STOCK APPRECIATION RIGHTS

         Upon the grant of a Stock Appreciation Right, or during the period
that the unexercised Stock Appreciation Right remains outstanding, the
Participant will not recognize any federal taxable income and the Company will
not be entitled to a federal income tax deduction. On the exercise of a Stock
Appreciation Right, the consideration paid to the Participant, whether in cash,
Shares or both, generally will constitute compensation taxable to the
Participant as ordinary income (in the same manner and at the same time
described in paragraph 1 above) and the Company is entitled to a corresponding
federal income tax deduction, provided it complies with the applicable
withholding requirements. Upon the sale of the Shares acquired by exercise of
Stock Appreciation Rights, the Participant will realize long-term or short-term
capital gain or loss, taxable as described in paragraph 1b. above.

3.       STOCK GRANT

         Under the Code, a Participant normally will not recognize taxable
income and the Company generally will not be entitled to a deduction upon the
grant of Shares of Restricted Stock. When the Shares are no longer subject to a
substantial risk of forfeiture (as defined in the Code) or become transferable,
the Participant will realize taxable ordinary income in an amount equal to the
fair market value of such number of Shares at the time, and the Company will be
entitled to a deduction in the same amount, provided the Company complies with
applicable withholding requirements.


                                      iii

<PAGE>   6




         Under Section 83(b) of the Code, a Participant may elect to realize
ordinary income in the year the Shares are awarded in an amount equal to their
fair market value at the time, determined without regard to the restrictions.
In that event, the Company will be entitled to a deduction in such year in the
same amount, provided the Company complies with applicable withholding
requirements, and any gain or loss realized by the Participant upon the
subsequent disposition of the Shares will be capital gain or loss (taxable as
described in paragraph 1 above) and will not result in any further deduction to
the Company. Any dividends with respect to the Shares of Restricted Stock which
are paid or made available to a Participant (who has not elected under Code
Section 83(b) to be taxed on the date of the grant) while the Shares remain
forfeitable are treated as additional compensation taxable as ordinary income
to the Participant and deductible to the Company. If an election under Code
Section 83(b) has been made with respect to the Shares, the dividends represent
ordinary dividend income to the Participant which are not deductible to the
Company. If the Participant elects to be taxed on the Shares of the Stock Grant
on the date of grant and the Participant subsequently forfeits the Shares, the
Participant is not entitled to a deduction as a consequence of such forfeiture,
and the Company must include as ordinary income the amount it previously
deducted (which amount is included in the Company's basis) in the year of grant
with respect to such Shares.

4.       PARACHUTE PAYMENTS

         The termination of restrictions on Stock Grants upon a Change in
Control, or the exercise of any portion of a Stock Option or related Stock
Appreciation Right which is accelerated as a result of a Change in Control, or
a similar event, may cause payments with respect to such Restricted Stock,
Deferred Stock, accelerated Stock Options, or related Stock Appreciation Rights
to be treated as "parachute payments" within the meaning of Section 28OG of the
Code. Any such parachute payments which constitute "excess parachute payments"
are nondeductible to the Company and subject the Participant to a 20% federal
excise tax under Section 4999 of the Code on such excess parachute payments, in
addition to other taxes ordinarily payable. Each Participant should consult his
or her personal tax advisor as to the potential impact of the parachute tax.

         to the remaining number of shares of Common Stock available under
         Article IV;

                  (m) to require as a condition of the exercise of an Award or
         the issuance or transfer of a certificate of Common Stock, the

<PAGE>   13


                  (t) to appoint and compensate agents, counsel, auditors or 
         other specialists to aid it in the discharge of its duties.

         The Board of Directors shall have the authority to adopt, alter and
repeal such administrative rules, guidelines and practices governing the Plan
as it shall, from time to time, deem advisable, to interpret the terms and
provisions of the Plan and any Award issued under the Plan (and any Agreement)
and to otherwise supervise the administration of the Plan. The Board of
Directors's policies and procedures may differ with respect to Awards granted
at different times or to different Participants.

         Any determination made by the Board of Directors pursuant to the
provisions of the Plan shall be made in its sole discretion, and in the case of
any determination relating to an Award, may be made at the time of the grant of
the Award or, unless in contravention of any express term of the Plan or an
Agreement, at any time thereafter. All decisions made by the Board of Directors
pursuant to the provisions of the Plan shall be final and binding on all
persons, including the Company and Participants. Any determination shall not be
subject to de novo review if challenged in court.

                                   ARTICLE IV

                             STOCK SUBJECT TO PLAN

         4.1 Number of Shares. Subject to the adjustment under Section 4.6, the
total number of shares of Common Stock reserved and available for distribution
pursuant to Awards under the Plan shall be 600,000 shares of Common Stock
authorized for issuance on the Effective Date. Such shares may consist, in
whole or in part, of authorized and unissued shares or treasury shares.

         4.2 Release of Shares. Subject to Section 7.3(f), if any shares of
Common Stock that have been optioned cease to be subject to an Award, if any
shares of Common Stock that are subject to any Award are forfeited, if any
Award otherwise terminates without issuance of shares of Common Stock being
made to the Participant, or if any shares (whether or not restricted) of Common
Stock that were previously issued under the Plan are received in connection
with the exercise of an Award, such shares, in the discretion of the Board of
Directors, may again be available for distribution in connection with Awards 
under the Plan.

         4.3 Restrictions on Shares. Shares of Common Stock issued upon
exercise of an Award shall be subject to the terms and conditions specified
herein and to such other terms, conditions and restrictions as the Board of
Directors in its discretion may determine or provide in the Award Agreement.
The Company shall not be required to issue or deliver any certificates for
shares of Common Stock, cash or other property prior to (i) the listing of such
shares on any stock exchange (or other public market) on which the Common Stock
may then be listed (or regularly traded), (ii) the completion of any
registration or qualification of such shares under federal or state law, or any
ruling or regulation of any government body which the Board of Directors
determines to be


                                       A7

<PAGE>   14



necessary or advisable. The Company may cause any certificate for any share of
Common Stock to be delivered to be properly marked with a legend or other
notation reflecting the limitations on transfer of such Common Stock as
provided in this Plan or as the Board of Directors may otherwise require. The
Board of Directors may require any person exercising an Award to make such
representations and furnish such information as it may consider appropriate in
connection with the issuance or delivery of the shares of Common Stock in
compliance with applicable law or otherwise. Fractional shares shall not be
delivered, but shall be rounded to the next lower whole number of shares.

         4.4 Shareholder Rights. No person shall have any rights of a
shareholder as to shares of Common Stock subject to an Award until, after
proper exercise of the Award or other action required, such shares shall have
been recorded on the Company's official shareholder records as having been
issued or transferred. Upon exercise of the Award or any portion thereof, the
Company will have thirty (30) days in which to issue the shares, and the
Participant will not be treated as a shareholder for any purpose whatsoever
prior to such issuance. No adjustment shall be made for cash dividends or other
rights for which the record date is prior to the date such shares are recorded
as issued or transferred in the Company's official shareholder records, except
as provided herein or in an Agreement.

         4.5 Best Efforts To Register. The Company will register under the
Securities Act the Common Stock delivered or deliverable pursuant to Awards on
Commission Form S-8 if available to the Company for this purpose (or any
successor or alternate form that is substantially similar to that form to the
extent available to effect such registration), in accordance with the rules and
regulations governing such forms, as soon as such forms are available for
registration to the Company for this purpose. The Company will use its best
efforts to cause the registration statement to become effective as soon as
possible and will file such supplements and amendments to the registration
statement as may be necessary to keep the registration statement in effect
until the earliest of (a) one year following the expiration of the Option
Period of the last Option outstanding, (b) the date the Company is no longer a
reporting company under the Exchange Act and (c) the date all Participants have
disposed of all shares delivered pursuant to any Award. The Company may delay
the foregoing obligation if the Board of Directors reasonably determines that
any such registration would materially and adversely affect the Company's
interests or if there is no material benefit to Participants.

         4.6 Anti-Dilution. In the event of any Company stock dividend, stock
split, combination or exchange of shares, recapitalization or other change in
the capital structure of the Company, corporate separation or division of the
Company (including, but not limited to, a split-up, spin-off, split-off or
distribution to Company shareholders other than a normal cash dividend), sale
by the Company of all or a substantial portion of its assets (measured on
either a stand-alone or consolidated basis), reorganization, rights offering, a
partial or complete liquidation, or any other corporate transaction, Company
share offering or event involving the Company and having an effect similar to
any of the foregoing, then the Board of Directors shall adjust or substitute,
as the case may be, the number of shares of Common Stock available for Awards
under the Plan, the number of


                                       A8

<PAGE>   15


shares of Common Stock covered by outstanding Awards, the exercise price per
share of outstanding Awards, and any other characteristics or terms of the
Awards as the Board of Directors shall deem necessary or appropriate to reflect
equitably the effects of such changes to the Participants; provided, however,
that any fractional shares resulting from such adjustment shall be eliminated
by rounding to the next lower whole number of shares with appropriate payment
for such fractional share as shall reasonably be determined by the Board of
Directors.

                                   ARTICLE V

                                  ELIGIBILITY

         5.1 Eligibility. Except as herein provided, the persons who shall be
eligible to participate in the Plan and be granted Awards shall be those
persons who are officers, non-employee directors, employees or consultants of
the Company or any subsidiary who shall be in a position, in the opinion of the
Board of Directors, to make contributions to the growth, management, protection
and success of the Company and its subsidiaries. Of those persons described in
the preceding sentence, the Board of Directors may, from time to time, select
persons to be granted Awards and shall determine the terms and conditions with
respect thereto. In making any such selection and in determining the form of
the Award, the Board of Directors may give consideration to the functions and
responsibilities of the person's contributions to the Company and its
subsidiaries, the value of the individual's service to the Company and its
subsidiaries and such other factors deemed relevant by the Board of Directors.
The Board of Directors may designate any person who is eligible to participate
in the Plan provided that such person is not a member of the Board of
Directors. A Board of Directors comprised of Non-Employee Directors may
designate a person serving on the Board of Directors provided that he or she
would otherwise be eligible.

                                   ARTICLE VI

                                 STOCK OPTIONS

         6.1 General. The Board of Directors shall have authority to grant
Options under the Plan at any time or from time to time. Stock Options may be
granted alone or in addition to other Awards and may be either Incentive Stock
Options or Non-Qualified Stock Options. An Option shall entitle the Participant
to receive shares of Common Stock upon exercise of such Option, subject to the
Participant's satisfaction in full of any conditions, restrictions or
limitations imposed in accordance with the Plan or an Agreement (the terms and
provisions of which may differ from other Agreements) including without
limitation, payment of the Option Price. During any calendar year, Options for
no more than 40,000 shares of Common Stock shall be granted to any Participant.

         6.2 Grant and Exercise.  The grant of a Stock Option shall occur as of 
the date the Board of Directors determines. Each Option granted under this Plan
shall be evidenced by an Agreement, in a form approved by the Board of
Directors, which shall embody the terms and conditions of such Option and which
shall be subject to the express terms and conditions set forth in the Plan.
Such


                                       A9

<PAGE>   16



Agreement shall become effective upon execution by the Participant. Only a
person who is a common-law employee of the Company, any parent corporation of
the Company or a subsidiary (as such terms are defined in Section 424 of the
Code) on the date of grant shall be eligible to be granted an Option which is
intended to be and is an Incentive Stock Option. To the extent that any Stock
Option is not designated as an Incentive Stock Option or even if so designated
does not qualify as an Incentive Stock Option, it shall constitute a
Non-Qualified Stock Option. Anything in the Plan to the contrary
notwithstanding, no term of the Plan relating to Incentive Stock Options shall
be interpreted, amended or altered, nor shall any discretion or authority
granted under the Plan be exercised, so as to disqualify the Plan under Section
422 of the Code or, without the consent of the Participant affected, to
disqualify any Incentive Stock Option under such Section 422.

         6.3 Terms and Conditions.  Stock Options shall be subject to such terms
and conditions as shall be determined by the Board of Directors, including the
following:

                  (a) Option Period. The Option Period of each Stock Option
         shall be fixed by the Board of Directors; provided that no
         Non-Qualified Stock Option shall be exercisable more than fifteen (15)
         years after the date the Stock Option is granted. In the case of an
         Incentive Stock Option, the Option Period shall not exceed ten (10)
         years from the date of grant or five (5) years in the case of an
         individual who owns more than ten percent (10%) of the combined voting
         power of all classes of stock of the Company, a corporation which is a
         parent corporation of the Company or any subsidiary of the Company
         (each as defined in Section 424 of the Code). No Option which is
         intended to be an Incentive Stock Option shall be granted more than
         ten (10) years from the date the Plan is adopted by the Company or the
         date the Plan is approved by the shareholders of the Company,
         whichever is earlier.

                  (b) Option Price. The Option Price per share of the Common
         Stock purchasable under an Option shall be determined by the Board of
         Directors, but in no event shall the Option Price be less than 50% of
         the Fair Market Value on the Grant Date. If such Option is intended to
         qualify as an Incentive Stock Option, the Option Price per share shall
         be not less than the Fair Market Value per share on the date the
         Option is granted, or where granted to an individual who owns or who
         is deemed to own stock possessing more than ten percent (10%) of the
         combined voting power of all classes of stock of the Company, a
         corporation which is a parent corporation of the Company or any
         subsidiary of the Company (each as defined in Section 424 of the
         Code), not less than one hundred ten percent (110%) of such Fair
         Market Value per share.

                  (c) Exercisability. Subject to Section 9.1, Stock Options
         shall be exercisable at such time or times and subject to such terms
         and conditions as shall be determined by the Board of Directors. If
         the Board of Directors provides that any Stock Option is exercisable
         only in installments, the Board of Directors may at any


                                      A10

<PAGE>   17


         time waive such installment exercise provisions, in whole or in part.
         In addition, the Board of Directors may at any time accelerate the
         exercisability of any Stock Option.

                  (d) Method of Exercise. Subject to the provisions of this
         Article VI, a Participant may exercise Stock Options, in whole or in
         part, at any time during the Option Period by the Participant's giving
         written notice of exercise on a form provided by the Board of
         Directors (if available) to the Company specifying the number of
         shares of Common Stock subject to the Stock Option to be purchased.
         Such notice shall be accompanied by payment in full of the purchase
         price by cash or check or such other form of payment as the Company
         may accept. If approved by the Board of Directors, payment in full or
         in part may also be made (i) by delivering Common Stock already owned
         by the Participant having a total Fair Market Value on the date of
         such delivery equal to the Option Price; (ii) by the execution and
         delivery of a note or other evidence of indebtedness (and any security
         agreement thereunder) satisfactory to the Board of Directors and
         permitted in accordance with Section 6.3(e); (iii) by authorizing the
         Company to retain shares of Common Stock which would otherwise be
         issuable upon exercise of the Option having a total Fair Market Value
         on the date of delivery equal to the Option Price; (iv) by the
         delivery of cash or the extension of credit by a broker-dealer to whom
         the Participant has submitted a notice of exercise or otherwise
         indicated an intent to exercise an Option (in accordance with Part
         220, Chapter 11, Title 12 of the Code of Federal Regulations,
         so-called "cashless" exercise); or (v) by any combination of the
         foregoing. If payment of the Option Price of a Non-Qualified Stock
         Option is made in whole or in part in the form of Restricted Stock or
         Deferred Stock, the number of shares of Common Stock to be received
         upon such exercise equal to the number of shares of Restricted Stock
         or Deferred Stock used for payment of the Option Price shall be
         subject to the same forfeiture restrictions or deferral limitations to
         which such Restricted Stock or Deferred Stock was subject, unless
         otherwise determined by the Board of Directors. In the case of an
         Incentive Stock Option, the right to make a payment in the form of
         already owned shares of Common Stock of the same class as the Common
         Stock subject to the Stock Option may be authorized only at the time
         the Stock Option is granted. No shares of Common Stock shall be issued
         until full payment therefor has been made. Subject to any forfeiture
         restrictions or deferral limitations that may apply if a Stock Option
         is exercised using Restricted Stock or Deferred Stock, a Participant
         shall have all of the rights of a shareholder of the Company holding
         the class of Common Stock that is subject to such Stock Option
         (including, if applicable, the right to vote the shares and the right
         to receive dividends), when the Participant has given written notice
         of exercise, has paid in full for such shares and such shares have
         been recorded on the Company's official shareholder records as having
         been issued or transferred.

                  (e) Company Loan or Guarantee.  Upon the exercise of any 
         Option and subject to the pertinent Agreement and the discretion of
         the Board of Directors, the Company may at the request of the
         Participant:

                  (i)   lend to the Participant, with recourse, an amount 
                  equal to such portion of the Option Price as the Board of 
                  Directors may determine; or

                  (ii)  guarantee a loan obtained by the Participant from a 
                  third-party for the purpose of tendering the Option Price.

The terms and conditions of any loan or guarantee, including the term, interest
rate, and any security interest thereunder, shall be determined by the Board of
Directors, except that no extension of credit or guarantee shall obligate the
Company for an amount to exceed the lesser of the aggregate Fair Market Value
per share of the Common Stock on the date of exercise, less the par value of
the shares of Common Stock to be purchased upon the exercise of the Award, or
the amount permitted under applicable laws or the regulations and rules of the
Federal Reserve Board and any other governmental agency having jurisdiction.

                  (f) Non-transferability of Options. No Incentive Stock Option
         or interest therein shall be transferable by the Participant other
         than by will or by the laws of descent or distribution, and all Stock
         Options shall be exercisable during the Participant's lifetime only by
         the Participant.

         6.4 Termination by Reason of Death, Disability or Retirement. Unless
otherwise provided in an Agreement or determined by the Board of Directors, if
a Participant incurs a Termination of Employment due to death, Disability or
Retirement, any unexpired and unexercised Stock Option held by such Participant
shall thereafter be fully exercisable for a period of five (5) years (or such
other period or no period as the Board of Directors may specify) immediately
following the date of such death, Disability or Retirement (as applicable) or
until the expiration of the Option Period, whichever period is the shorter. In
the event of Termination of Employment by reason of Disability, if an Incentive
Stock Option is exercised after the expiration of the exercise periods that
apply for purposes of Section 422 of the Code, such Stock Option will
thereafter be treated as a Non-Qualified Stock Option.

         6.5 Other Termination. Unless otherwise provided in an Agreement or
determined by the Board of Directors, if a Participant incurs a Termination of
Employment that is not due to death, Retirement, Disability or with Cause) any
Stock Option held by such Participant shall thereupon terminate, except that
such Stock Option, to the extent then exercisable, may be exercised for the
lesser of a period of two (2) years commencing with the date of such
Termination of Employment or until the expiration of the Option Period, or in
the case of a voluntary Termination of Employment (other than due to death,
Retirement, Disability or with Cause), for a period of six (6) months
commencing with the date of such Termination of Employment in the case of a
voluntary


                                      A12

<PAGE>   19


Termination of Employment or until the expiration of the Option Period,
whichever is less. If the Participant incurs a Termination of Employment which
is with Cause, the Option shall terminate immediately. The death, Disability or
Retirement of a Participant after a Termination of Employment otherwise
provided herein shall not extend the exercisability of the time permitted to
exercise an Option.

         6.6 Cashing Out of Option. On receipt of written notice of exercise,
the Board of Directors may elect to cash out all or part of the portion of any
Stock Option to be exercised by paying the Participant an amount, in cash or
Common Stock, equal to the excess of the Fair Market Value of the Common Stock
that is subject to the Option over the Option Price times the number of shares
of Common Stock subject to the Option on the effective date of such cash out.
The Board of Directors may determine Fair Market Value under the pricing rule
set forth in Section 7.3(b).

                                  ARTICLE VII

                           STOCK APPRECIATION RIGHTS

         7.1 General. The Board of Directors shall have authority to grant
Stock Appreciation Rights under the Plan at any time or from time to time.
Subject to the Participant's satisfaction in full of any conditions,
restrictions or limitations imposed in accordance with the Plan or an
Agreement, a Stock Appreciation Right shall entitle the Participant to
surrender to the Company the Stock Appreciation Right and to be paid therefor
in shares of the Common Stock, cash or a combination thereof as herein
provided, the amount described in Section 7.3(b).

         7.2 Grant. Stock Appreciation Rights may be granted in conjunction
with all or part of any Stock Option granted under the Plan in which case the
exercise of the Stock Appreciation Right shall require the cancellation of a
corresponding portion of the Stock Option and the exercise of the Stock Option
will result in the cancellation of a corresponding portion of the Stock
Appreciation Right. In the case of a Non-Qualified Stock Option, such rights
may be granted either at or after the time of grant of such Stock Option. In
the case of an Incentive Stock Option, such rights may be granted only at the
time of grant of such Stock Option. A Stock Appreciation Right may also be
granted on a stand alone basis. The grant of a Stock Appreciation Right shall
occur as of the date the Board of Directors determines. Each Stock Appreciation
Right granted under this Plan shall be evidenced by an Agreement, which shall
embody the terms and conditions of such Stock Appreciation Right and which
shall be subject to the terms and conditions set forth in the Plan. During any
calendar year, no more than 40,000 Stock Appreciation Rights shall be granted
to any Participant.

         7.3 Terms and Conditions. Stock Appreciation Rights shall be subject
to such terms and conditions as shall be determined by the Board of Directors,
including the following:

                  (a) Period and Exercise.  The term of a Stock Appreciation 
         Right shall be established by the Board of Directors. If granted in
         conjunction with a Stock


                                      A13

<PAGE>   20



         Option, the Stock Appreciation Right shall have a term which is the
         same as the Option Period and shall be exercisable only at such time
         or times and to the extent the related Stock Options would be
         exercisable in accordance with the provisions of Article VI. A Stock
         Appreciation Right which is granted on a stand alone basis shall be
         for such period and shall be exercisable at such times and to the
         extent provided in an Agreement. Stock Appreciation Rights shall be
         exercised by the Participant's giving written notice of exercise on a
         form provided by the Board of Directors (if available) to the Company
         specifying the portion of the Stock Appreciation Right to be
         exercised.

                  (b) Amount. Upon the exercise of a Stock Appreciation Right,
         a Participant shall be entitled to receive an amount in cash, shares
         of Common Stock or both as determined by the Board of Directors or as
         otherwise permitted in an Agreement equal in value to the excess of
         the Fair Market Value per share of Common Stock over the Option Price
         per share of Common Stock specified in the related Agreement
         multiplied by the number of shares in respect of which the Stock
         Appreciation Right is exercised. In the case of a Stock Appreciation
         Right granted on a stand alone basis, the Agreement shall specify the
         value to be used in lieu of the Option Price per share of Common
         Stock. The aggregate Fair Market Value per share of the Common Stock
         shall be determined as of the date of exercise of such Stock
         Appreciation Right.

                  (c) Special Rules. In the case of Stock Appreciation Rights
         relating to Stock Options held by Participants who are actually or
         potentially subject to Section 16(b) of the Exchange Act; no Stock
         Appreciation Right shall be exercisable during the first six months of
         its term, except that this limitation shall not apply in the event of
         death or Disability of the Participant prior to the expiration of the
         six-month period.

                  (d) Non-transferability of Stock Appreciation Rights.  Stock 
         Appreciation Rights shall be transferable only when and to the extent
         that a Stock Option would be transferable under the Plan unless
         otherwise provided in an Agreement.

                  (e) Termination. A Stock Appreciation Right shall terminate
         at such time as a Stock Option would terminate under the Plan, unless
         otherwise provided in an Agreement.

                  (f) Incentive Stock Option. A Stock Appreciation Right
         granted in tandem with an Incentive Stock Option shall not be
         exercisable unless the Fair Market Value of the Common Stock on the
         date of exercise exceeds the Option Price. In no event shall any
         amount paid pursuant to the Stock Appreciation Right exceed the
         difference between the Fair Market Value on the date of exercise and
         the Option Price.

                                  ARTICLE VIII

                                  STOCK GRANTS

         8.1 General. The Board of Directors shall have authority to make a
Stock Grant under the Plan at any time or from time to time. Shares of Stock
may be awarded either alone or in addition to other Awards granted under the
Plan. The Board of Directors shall determine the persons to whom and the time
or times at which a Stock Grant will be awarded, the number of shares of Shares
to be awarded to any Participant, the time or times within which such Awards
may be subject to forfeiture and any other terms and conditions of the Awards.
Each Award shall be confirmed by, and be subject to the terms of, an Agreement.
The Board of Directors may condition the grant of Stock upon the attainment of
specified performance goals by the Participant or by the Company or an
Affiliate (including a division or department of the Company or an Affiliate)
for or within which the Participant is primarily employed or upon such other
factors or criteria as the Board of Directors shall determine. The provisions
of Stock Grants need not be the same with respect to any Participant.

         8.2 Awards and Certificates. Notwithstanding the limitations on
issuance of shares of Common Stock otherwise provided in the Plan, each
Participant receiving a Stock Grant Award shall be issued a certificate in
respect of such shares. Such certificate shall be registered in the name of
such Participant and shall bear an appropriate legend referring to the terms,
conditions, and restrictions applicable to such Award as determined by the
Board of Directors. The Board of Directors may require that the certificates
evidencing such shares be held in custody by the Company until the restrictions
thereon shall have lapsed and that, as a condition of any Stock Grant Award,
the Participant shall have delivered a stock power, endorsed in blank, relating
to the Common Stock covered by such Award. During any calendar year, no more
than 40,000 shares shall be granted to any Participant.

         8.3 Terms and Conditions.  Stock Grant shares shall be subject to the 
following terms and conditions:

                  (a) Limitations on Transferability. Subject to the provisions
         of the Plan and except as provided in an Agreement, during a period
         set by the Board of Directors, commencing with the date of such Award
         (the "Restriction Period"), the Participant shall not be permitted to
         sell, assign, transfer, pledge or otherwise encumber any interest in
         Stock Grant shares.

                  (b) Rights. Except as provided in Section 8.3(a), the
         Participant shall have, with respect to the Stock Grant shares, all of
         the rights of a shareholder of the Company holding the class of Common
         Stock that is the subject of the Stock Grant, including, if
         applicable, the right to vote the shares and the right to receive any
         cash dividends. Unless otherwise determined by the Board of Directors
         and subject to the Plan, cash dividends on the class of Common Stock
         that is the subject of the Stock


                                      A15

<PAGE>   22


         Grant shall be automatically deferred and reinvested in additional
         restricted stock, and dividends on the class of Common Stock that is
         the subject of the Stock Grant payable in Common Stock shall be paid
         in the form of the same class as the Common Stock on which such
         dividend was paid.

                  (c) Criteria. Based on service, performance by the
         Participant or by the Company or the Affiliate, including any division
         or department for which the Participant is employed or such other
         factors or criteria as the Board of Directors may determine, the Board
         of Directors may provide for the lapse of restrictions in installments
         and may accelerate the vesting of all or any part of any Award and
         waive the restrictions for all or any part of such Award.

                  (d) Forfeiture. Unless otherwise provided in an Agreement or
         determined by the Board of Directors, if the Participant incurs a
         Termination of Employment during the Restriction Period due to death
         or Disability, the restrictions shall lapse and the Participant shall
         be fully vested in the Stock Grant. Except to the extent otherwise
         provided in the applicable Agreement and the Plan, upon a
         Participant's Termination of Employment for any reason during the
         Restriction Period other than death or Disability, all shares of the
         Stock Grant still subject to restriction shall be forfeited by the
         Participant, except the Board of Directors shall have the discretion
         to waive in whole or in part any or all remaining restrictions with
         respect to any or all of such Participant's shares under the Stock
         Grant.

                  (e) Delivery. If and when the Restriction Period expires
         without a prior forfeiture of the stock subject to such Restriction
         Period, unlegended certificates for such shares shall be delivered to
         the Participant.

                  (f) Election. A Participant may elect to further defer
         receipt of the shares under the Stock Grant for a specified period or
         until a specified event, subject in each case to the Board of
         Directors's approval and to such terms as are determined by the Board
         of Directors. Subject to any exceptions adopted by the Board of
         Directors, such election must be made one (1) year prior to completion
         of the Restriction Period.

                          CHANGE IN CONTROL PROVISIONS

to the contrary, in the event of a Change in Control (as defined in Section
9.2):

<PAGE>   23


                  (a) Any Stock Appreciation Rights and Stock Options
         outstanding as of the date such Change in Control and not then
         exercisable shall become fully exercisable to the full extent of the
         original grant.

                  (b) The restrictions and deferral limitations applicable to
         any Stock Grant shall lapse, and such restricted stock shall become
         free of all restrictions and become fully vested and transferable to
         the full extent of the original grant.

                  (c) Notwithstanding any other provision of the Plan, unless
         the Board of Directors shall provide otherwise in an Agreement, a
         Participant shall have the right, whether or not the Award is fully
         exercisable or may be otherwise realized by the Participant, by giving
         notice during the 60-day period from and after a Change in Control to
         the Company, to elect to surrender all or part of the Award to the
         Company and to receive cash, within 30 days of such notice, in an
         amount equal to the amount by which the "Change in Control Price" (as
         defined in Section 9.3) per share of Common Stock on the date of such
         election shall exceed the amount which the Participant must pay to
         exercise the Award per share of Common Stock under the Award (the
         "Spread") multiplied by the number of shares of Common Stock granted
         under the Award as to which the right granted hereunder shall have
         been exercised; provided, however, that if the end of such 60-day
         period from and after a Change in Control is within six months of the
         date of grant of the Award held by a Participant (except a Participant
         who has died during such six month period) who is an officer or
         director of the Company (within the meaning of Section 16b of the
         Exchange Act), such Award shall be canceled in exchange for a payment
         to the Participant at the time of the Participant's Termination of
         Employment, equal to the Spread multiplied by the number of shares of
         Common Stock granted under the Award, plus interest on such amount at
         the prime rate compounded annually and determined from time to time.

         9.2 Definition of Change in Control.  For purposes of the Plan, a 
"Change in Control" shall mean the happening of any of the following events:

                  (a) there shall be consummated (i) any consolidation or
         merger of the Company in which the Company is not the continuing or
         surviving corporation or pursuant to which shares of the Company's
         common stock would be converted into cash, securities or other
         property, other than a merger of the Company in which the holders of
         the Company's common stock immediately prior to the merger have
         substantially the same proportionate ownership of common stock of the
         surviving corporation immediately after the merger; or (ii) any sale,
         lease, exchange or other transfer (in one transaction or a series of
         related transactions) of all or substantially all of the assets of the
         Company; or


                                      A17

<PAGE>   24


                  (b) the shareholders of the Company shall approve any plan or
         proposal for the liquidation or dissolution of the Company; or

                  (c) any person (as such term is used in Sections 13d and
         14d(2) of the Exchange Act), other than the Company or any employee
         benefit plan sponsored by the Company, shall become the beneficial
         owner (within the meaning of Rule 13d-3 under the Exchange Act) of
         securities of the Company representing an amount greater than two
         times the aggregate percentage held or controlled by Cottonwood
         Partnership and Adams Affiliates, Inc. (and apart from rights accruing
         in special circumstances) having the right to vote in the election of
         directors, as a result of a tender or exchange offer, open market
         purchases, privately negotiated purchases or otherwise; or

                  (d) any three persons (as such term is used in Sections 13d
         and 14d(2) of the Exchange Act), other than the Company or any
         employee benefit plan sponsored by the Company, shall become the
         beneficial owner (within the meaning of Rule 13d-3 under the Exchange
         Act) of securities of the Company whose ownership represents an amount
         greater than four times the aggregate percentage held or controlled by
         Cottonwood Partnership and Adams Affiliates, Inc. combined (and apart
         from rights accruing in special circumstances) having the right to
         vote in election of directors, as a result of a tender or exchange
         offer, open market purchases, privately negotiated purchases or
         otherwise; or

                  (e) at any time during a period of two consecutive years,
         individuals who at the beginning of such period constituted the Board
         of Directors of the Company shall cease for any reason to constitute
         at least a majority thereof, unless the election or the nomination for
         election by the Company's shareholders of each new director during
         such two-year period was approved by a vote of at least two-thirds of
         the directors then still in office who were directors at the beginning
         of such two-year period. A Change of Control shall not be deemed to
         have occurred if banks or other creditors receive the Company's stock
         in conjunction with transactions involving forgiveness of outstanding
         debt or debt restructuring agreements.

                  (f) at any time an individual is elected to the Board of 
         Directors who was not nominated by the Board of Directors of the
         Company to stand for election.

         9.3 Change in Control Price. For purposes of the Plan, "Change in
Control Price" means the higher of (a) the highest reported sales price of a
share of Common Stock in any transaction reported on NASDAQ or other principal
exchange on which such shares are listed during the 60-day period prior to and
including the date of a Change in Control or (b) if the Change in Control is
the result of a tender or exchange offer or a Corporate Transaction, the
highest price per share of Common Stock paid in such tender or exchange offer
or a Corporate Transaction, except that, in the case of Incentive Stock Options
and Stock Appreciation Rights relating to Incentive Stock Options,


                                      A18

<PAGE>   25


such price shall be based only on the Fair Market Value of the Common Stock on
the date such Incentive Stock Option or Stock Appreciation Right is exercised.
To the extent that the consideration paid in any such transaction described
above consists all or in part of securities or other non-cash consideration,
the value of such securities or other non-cash consideration shall be
determined in the sole discretion of the Board of Directors.

                                   ARTICLE X

                                 MISCELLANEOUS

         10.1 Amendments and Termination. The Board may amend, alter,
discontinue or terminate the Plan at any time, but no amendment, alteration,
discontinuation or termination shall be made which would impair the rights of a
Participant under a Stock Option, Stock Appreciation Right or Stock Grant
theretofore granted without the Participant's consent. In addition, no such
amendment shall be made without the approval of the Company's shareholders to
the extent such approval is required by law or agreement.

         The Board of Directors may amend the Plan at any time provided that
(a) no amendment shall impair the rights of any Participant under any Award
theretofore granted without the Participant's consent, and (b) any amendment
shall be subject to the approval or rejection of the Board.

         The Board of Directors may amend the terms of any Award or other Award
theretofore granted, prospectively or retroactively, but no such amendment
shall impair the rights of any Participant without the Participant's consent.
The Board of Directors may also substitute new Stock Options or Stock
Appreciation Rights for previously granted Stock Options, including previously
granted Stock Options or Stock Appreciation Rights having higher Option Prices
but no such substitution shall be made which would impair the rights of
Participants under such Stock Option or Stock Appreciation Right theretofore
granted without the Participant's consent.

         Subject to the above provisions, the Board shall have authority to
amend the Plan to take into account changes in law and tax and accounting
rules, as well as other developments and to grant Awards which qualify for
beneficial treatment under such rules without shareholder approval.

         10.2 Unfunded Status of Plan. It is intended that the Plan be an
"unfunded" plan for incentive and deferred compensation. The Board of Directors
may authorize the creation of trusts or other arrangements to meet the
obligations created under the Plan to deliver Common Stock or make payments;
provided, however, that, unless the Board of Directors otherwise determines,
the existence of such trusts or other arrangements is consistent with the
"unfunded" status of the Plan.

<PAGE>   26


         10.3     General Provisions.

                  (a) Representation. The Board of Directors may require each
         person purchasing or receiving shares pursuant to an Award to
         represent to and agree with the Company in writing that such person is
         acquiring the shares without a view to the distribution thereof. The
         certificates for such shares may include any legend which the Board of
         Directors deems appropriate to reflect any restrictions on transfer.

                  (b) No Additional Obligation.  Nothing contained in the 
         Plan shall prevent the Company or an Affiliate from adopting other or
         additional compensation arrangements for its employees.

                  (c) Withholding. No later than the date as of which an amount
         first becomes includible in the gross income of the Participant for
         Continental Natural Gas, Inc. income tax purposes with respect to any
         Award, the Participant shall pay to the Company (or other entity
         identified by the Board of Directors), or make arrangements
         satisfactory to the Company or other entity identified by the Board of
         Directors regarding the payment of any federal, state, local or
         foreign taxes of any kind required by law to be withheld with respect
         to such amount required in order for the Company or an Affiliate to
         obtain a current deduction. Unless otherwise determined by the Board
         of Directors, withholding obligations may be settled with Common
         Stock, including Common Stock that is part of the Award that gives
         rise to the withholding requirement provided that any applicable
         requirements under Section 16 of the Exchange Act are satisfied. The
         obligations of the Company under the Plan shall be conditional on such
         payment or arrangements, and the Company and its Affiliates shall, to
         the extent permitted by law, have the right to deduct any such taxes
         from any payment otherwise due to the Participant.

                  (d) Reinvestment. The reinvestment of dividends in additional
         Deferred or Restricted Stock at the time of any dividend payment shall
         only be permissible if sufficient shares of Common Stock are available
         for such reinvestment (taking into account then outstanding Options
         and other Awards).

                  (e) Representation. The Board of Directors shall establish
         such procedures as it deems appropriate for a Participant to designate
         a Representative to whom any amounts payable in the event of the
         Participant's death are to be paid.

                  (f) Controlling Law. The Plan and all Awards made and actions
         taken thereunder shall be governed by and construed in accordance with
         the laws of the State of Oklahoma. The Plan shall be construed to
         comply with all applicable law, and to avoid liability to the Company,
         an Affiliate or a Participant, including, without limitation,
         liability under Section 16b of the Exchange Act.


                                      A20

<PAGE>   27


                  (g) Offset. Any amounts owed to the Company or an Affiliate
         by the Participant of whatever nature may be offset by the Company
         from the value of any shares of Common Stock, cash or other thing of
         value under this Plan or an Agreement to be transferred to the
         Participant, and no shares of Common Stock, cash or other thing of
         value under this Plan or an Agreement shall be transferred unless and
         until all disputes between the Company and the Participant have been
         fully and finally resolved and the Participant has waived all claims
         to such against the Company or an Affiliate.

         10.4 Mitigation of Excise Tax. If any payment or right accruing to a
Participant under this Plan (without the application of this Section 10.4),
either alone or together with other payments or rights accruing to the
Participant from the Company or an Affiliate ("Total Payments") would
constitute a "parachute payment" (as defined in Section 28OG of the Code and
regulations thereunder), such payment or right shall be reduced to the largest
amount or greatest right that will result in no portion of the amount payable
or right accruing under the Plan being subject to an excise tax under Section
4999 of the Code or being disallowed as a deduction under Section 28OG of the
Code. The determination of whether any reduction in the rights or payments
under this Plan is to apply shall be made by the Board of Directors in good
faith after consultation with the Participant, and such determination shall be
conclusive and binding on the Participant. The Participant shall cooperate in
good faith with the Board of Directors in making such determination and
providing the necessary information for this purpose. The foregoing provisions
of this Section 10.4 shall apply with respect to any person only if after
reduction for any applicable federal excise tax imposed by Section 4999 of the
Code and federal income tax imposed by the Code, the Total Payments accruing to
such person would be less than the amount of the Total Payments as reduced, if
applicable, under the foregoing provisions of the Plan and after reduction for
only federal income taxes.

         10.5 Rights with Respect to Continuance of Employment. Nothing
contained herein shall be deemed to alter the relationship between the Company
or an Affiliate and a Participant, or the contractual relationship between a
Participant and the Company or an Affiliate if there is a written contract
regarding such relationship. Nothing contained herein shall be construed to
constitute a contract of employment between the Company or an Affiliate and a
Participant. The Company or an Affiliate and each of the Participants continue
to have the right to terminate the employment or service relationship at any
time for any reason, except as provided in a written contract. The Company or
an Affiliate shall have no obligation to retain the Participant in its employ
or service as a result of this Plan. There shall be no inference as to the
length of employment or service hereby, and the Company or an Affiliate
reserves the same rights to terminate the Participant's employment or service
as existed prior to the individual becoming a Participant in this Plan.

         10.6 Awards in Substitution for Awards Granted by Other Corporations.
Awards may be granted under the Plan from time to time in substitution for
awards held by employees, directors or service providers of other corporations
who are about to become officers, directors or employees of the Company or an
Affiliate as the result of a merger or consolidation of the employing
corporation with the Company or an Affiliate, or the acquisition by the Company
or an Affiliate of


                                      A21

<PAGE>   28


the assets of the employing corporation, or the acquisition by the Company or
Affiliate of the stock of the employing corporation, as the result of which it
becomes a designated employer under the Plan. The terms and conditions of the
Awards so granted may vary from the terms and conditions set forth in this Plan
at the time of such grant as the majority of the members of the Board of
Directors may deem appropriate to conform, in whole or in part, to the
provisions of the awards in substitution for which they are granted.

         10.7 Procedure for Adoption. Any Affiliate of the Company may by
resolution of such Affiliate's board of directors, with the consent of the
Board of Directors and subject to such conditions as may be imposed by the
Board of Directors, adopt the Plan for the benefit of its employees as of the
date specified in the board resolution.

         10.8 Procedure for Withdrawal. Any Affiliate which has adopted the
Plan may, by resolution of the board of directors of such direct or indirect
subsidiary, with the consent of the Board of Directors and subject to such
conditions as may be imposed by the Board of Directors, terminate its adoption
of the Plan. If the Participant disposes of shares of Common Stock acquired
pursuant to an Incentive Stock Option in any transaction considered to be a
disqualifying transaction under the Code, the Participant must give written
notice of such transfer and the Company shall have the right to deduct any
taxes required by law to be withheld from any amounts otherwise payable to the
Participant.

         10.9 Delay. If at the time a Participant incurs a Termination of
Employment (other than due to Cause) or if at the time of a Change in Control,
the Participant is subject to "short-swing" liability under Section 16 of the
Exchange Act, any time period provided for under the Plan or an Agreement to
the extent necessary to avoid the imposition of liability shall be suspended
and delayed during the period the Participant would be subject to such
liability, but not more than six (6) months and one (1) day and not to exceed
the Option Period, or the period for exercise of a Stock Appreciation Right as
provided in the Agreement, whichever is shorter. The Company shall have the
right to suspend or delay any time period described in the Plan or an Agreement
if the Board of Directors shall determine that the action may constitute a
violation of any law or result in liability under any law to the Company, an
Affiliate or a shareholder of the Company until such time as the action
required or permitted shall not constitute a violation of law or result in
liability to the Company, an Affiliate or a shareholder of the Company.

         10.10 Headings. The headings contained in this Plan are for reference
purposes only and shall not affect the meaning or interpretation of this Plan.

         10.11 Severability. If any provision of this Plan shall for any reason
be held to be invalid or unenforceable, such invalidity or unenforceability
shall not effect any other provision hereby, and this Plan shall be construed
as if such invalid or unenforceable provision were omitted.

         10.12 Successors and Assigns. This Plan shall inure to the benefit of 
and be binding upon each successor and assign of the Company. All obligations
imposed upon a Participant, and all


                                      A22

<PAGE>   29


rights granted to the Company hereunder, shall be binding upon the
Participant's heirs, legal representatives and successors.

         10.13 Entire Agreement. This Plan and the Agreement constitute the
entire agreement with respect to the subject matter hereof and thereof,
provided that in the event of any inconsistency between the Plan and the
Agreement, the terms and conditions of the Agreement shall Control.

         EXECUTED on this day of July 30, 1997.

<PAGE>   32


         2.       Termination of Option.  Subject to the schedule of 
Section 1(c).

                  (a) If the Termination of Employment is on account of the
         death of the Participant, this Option shall be canceled five (5) years
         after the date of the occurrence of the death or after the remaining
         Option Period if shorter.

                  (b) If a Participant incurs a Termination of Employment for
         reasons of a Disability, this Option shall be canceled one (1) year
         after such Termination of Employment or after the remaining Option
         Period if shorter.

                  (c) If a Participant incurs a Termination of Employment
         (other than due to Disability or death), this Option will

         Employment or after the remaining Option Period, if shorter.

                  (d) If a Participant incurs a Termination of Employment for
         Cause, the Option will be automatically canceled with the date of the

         3.       Exercise.

         The Option shall be exercisable during the Participant's lifetime only
by the Participant or his or her Representative, and after the Participant's
death only by a Representative. The Option may only be exercised by the
delivery to the Company of a properly completed written notice, in form
satisfactory to the Board of Directors, which notice shall specify the number
of Option Shares to be purchased and the aggregate Option Price for such
shares, together with payment in full of such aggregate Option Price. Payment
shall be made in one or more of the following methods and in a manner so as not
to violate Rule 16b of the Securities and Exchange Act of 1 934, as amended:

                  (a) in cash or by check;

                  (b) by the delivery to the Company of a valid and enforceable
         stock certificate (or certificates) representing shares of Common
         Stock, which is endorsed in blank or accompanied by an executed stock
         power (or powers) and guaranteed in a manner acceptable to the Board
         of Directors;

                  (c) by reducing the number of shares of Common Stock to be 
         issued and delivered to the Participant upon such exercise;

                  (d) in cash by a broker-dealer to whom the Participant has 
         submitted a notice of exercise; or

                  (e) in any combination of (a), (b), (c) or (d).

<PAGE>   33


If any part of the payment of the Option Price is made in shares of Common
Stock, such shares shall be valued by using their Fair Market Value as of their
date of delivery.

         The Option shall not be exercised unless there has been compliance
with all the preceding provisions of this Section 3, and, for all purposes of
this Incentive Stock Option Agreement, the date of the exercise of the Option
shall be the date upon which there is compliance with all such requirements.

         4.       Payment of Withholding Taxes.

         If the Company is obligated to withhold an amount on account of any
federal, state or local tax imposed as a result of the exercise of the Option,
including, without limitation, any federal, state or other income tax, or any
F.I.C.A., state disability insurance tax or other employment tax, then the
Participant shall (1) pay, concurrently with such exercise, such amount to the
Company in cash or by check payable to the Company; (2) irrevocably elect at
least six (6) months in advance of such exercise (or elect incident to a
Termination of Employment, Retirement, death or Disability) to have shares of
Common Stock, which would otherwise be issued, withheld by the Company; or (3)
as otherwise permitted by the Plan.

         5.       Requirements of Law; Registration and Transfer Requirements.

         The Company shall not be required to sell or issue any shares under
the Option if the issuance of such shares shall constitute a violation of any
provision of any law or regulation of any governmental authority. This Option
and each and every obligation of the Company hereunder are subject to the
requirement that the Option may not be exercised or performed, in whole or in
part, unless and until the Option Shares are listed, registered or qualified,
properly marked with a legend or other notation, or otherwise restricted, as is
provided for in the Plan.

         6.       Adjustments/Change in Control.

         In the event of a Change in Control or other corporate restructuring
provided for in the Plan, the Participant shall have such rights, and the Board
of Directors shall take such actions, as are provided for in the Plan.

         7.       Nontransferability.

         The Option and any interest in the Option may not be sold, assigned,
conveyed, gifted, pledged, hypothecated or otherwise transferred in any manner
other than by will or the laws of descent and distribution. Notwithstanding any
other provision of this Incentive Stock Option Agreement, any such attempted
sale, assignment, conveyance, gift, pledge, hypothecation or transfer shall be
null and void and shall nullify the Option immediately.

         8.       Plan.

         Notwithstanding any other provision of this Incentive Stock Option
Agreement, the Option is granted pursuant to the Plan, as in effect on the date
hereof, and is subject to all the terms and conditions of the Plan, as the same
may be amended from time to time; provided, however, that no amendment to
either the Plan or this Incentive Stock Option Agreement shall deprive the
Participant, without the Participant's consent, of the Option or of any of
Participant's rights under this Incentive Stock Option Agreement. The
interpretation and construction by the Board of Directors of the Plan, this
Incentive Stock Option Agreement, the Option, and such rules and regulations as
may be adopted by the Board of Directors for the purpose of administering the
Plan, shall be final and binding upon the Participant. Until the Option shall
expire, terminate or be exercised in full, the Company shall, upon written
request therefor, send a copy of the Plan, in its then-current form, to the
Participant or any other person or entity then entitled to exercise the Option.

         Participant hereby acknowledges receipt of a copy of the Plan.

         9.       Stockholder Rights.

         Until the Option shall have been duly exercised to purchase such
Option Shares and such shares have been officially recorded as issued on the
Company's official stockholder records, no person or entity shall be entitled
to vote, receive dividends or be deemed for any purpose the holder of any
Option Shares, and adjustments for dividends or otherwise shall be made only if
the record date therefor is subsequent to the date such shares are recorded and
after the date of exercise and without duplication of any adjustment.

         10.      Employment Rights.

         No provision of this Incentive Stock Option Agreement or of the Option
granted hereunder shall give the Participant any right to continue in the
employ of the Company or any of its Affiliates, create any inference as to the
length of employment of the Participant, affect the right of the Company or its
Affiliates to Terminate the Employment of the Participant, with or without
Cause, or give the Participant any right to participate in any employee welfare
or benefit plan or other program (other than the Plan) of the Company or any of
its Affiliates.

         11.      Disclosure Rights.

         The Company shall have no duty or obligation to affirmatively disclose
to the Participant or a Representative, and the Participant or Representative
shall have no right to be advised of, any material information regarding the
Company or an Affiliate at any time prior to, upon or in connection with the
exercise of an Option or the Company's purchase of Common Stock in accordance
with the terms of this Incentive Stock Option Agreement.

         The Board of Directors may require the Participant to furnish to the
Company, prior to the issuance of any shares of Common Stock upon the exercise
of all or any part of this Option, an agreement (in such form as such Board of
Directors may specify) in which the Participant represents that the shares of
Common Stock acquired by him upon exercise are being acquired for investment
and not with a view to the sale or distribution thereof.

         13.      Governing Law.

         This Incentive Stock Option Agreement and the Option granted hereunder

understanding with respect to this transaction.

         15.      Definitions.

         Wherever initial capitalization of a term is used in this Incentive
Stock Option Agreement, it shall have the same meaning as that given to it by
the Plan, except to the extent such meaning should conflict with any meaning
afforded to such term in this Incentive Stock Option Agreement.

         16.      Amendment.

         Any amendment to this Incentive Stock Option Agreement shall be in
writing and signed by the Company.

         17.      Waiver; Cumulative Rights.

         The failure or delay of either party to require performance by the
other party of any provision hereof shall not affect its right to require
performance of such provision unless and until such performance has been waived
in writing. Each and every right hereunder is cumulative and may be exercised
in part or in whole from time to time.

         18.      Counterparts.

                             STOCK GRANT AGREEMENT

         STOCK GRANT AGREEMENT dated as of between CONTINENTAL NATURAL GAS,
INC., an Oklahoma corporation (the "Company"), and , an (officer, non-employee
director, employee or consultant) of the Company or one of its subsidiaries
(the "Holder").

         WHEREAS, the Board of Directors of the Company has established 
Continental Natural Gas, Inc. 1997 Stock Plan (the "Plan");

         WHEREAS, the Plan's Board of Directors, in accordance with the
provisions of the Plan, has selected the Holder as a salaried key management
employee who, in the Board of Directors's judgment, has significant potential
for making substantial contributions to corporate growth and objectives;

         WHEREAS, in order to reward the Holder for services to be rendered in
a manner that relates directly to the Company's earnings growth and further the
identity of interests of the Holder and the Company's shareholders through
opportunities for increased stock ownership by the Holder, each Board of
Directors has determined that the Holder receive a Stock Grant under the Plan;

         NOW, THEREFORE, in consideration of the foregoing and the Holder's
acceptance of the terms and conditions hereof, the parties hereto have agreed,
and do hereby agree, as follows:

         1. The Company hereby grants to the Holder, as a matter of separate
agreement and not in lieu of salary or any other compensation for services,
shares of Common Stock of the Company on the terms and conditions herein set
forth.

         2. The certificates representing the shares of Common Stock granted to
the Holder shall be registered in the name of the Holder and retained in the
custody of the Company until such time as they are delivered to the Holder or
forfeited to the Company in accordance with the terms hereof (the "Restriction
Period"). During the Restriction Period, the Holder will be entitled to vote
such shares and to receive dividends paid on such shares (less any amounts
which the Company is required to withhold for taxes).

         3. If the Holder shall not have incurred a Termination of Employment 
prior to ______________ , the Company shall deliver to the Holder on or about 
such date a certificate, registered in the name of the Holder and free of
restrictions hereunder, representing ____% of the total number of shares
granted to the Holder pursuant to this Agreement. If the Holder shall be so
continuously employed on , the Company on or about such date shall deliver
additional certificates representing ____% of the total number of such shares.
If the Holder shall be so continuously employed on _______________________, the 
Company on or about such date shall deliver additional certificates
representing ____% of the total number of such shares. If the Holder shall be

deliver additional certificates representing ____% of the total number of such
shares. No payment (except for tax withholding) shall be required from the
Holder in connection with any delivery to the Holder of shares hereunder.

         4. In the event the Holder has a Termination of Employment for reasons
of Retirement at or after age 65, or Disability, and if there then remain any
undelivered shares subject to restrictions hereunder, then such restrictions
shall be deemed to have lapsed and the certificates for the remaining shares
shall forthwith be delivered to such retired Holder.

         5. Subject to the provisions of paragraph 4 above, if the Holder has a
Termination of Employment for any reason (including Retirement prior to age 65
or death) during the Restriction Period, then the Holder shall cease to be
entitled to delivery of any of the shares covered by this Agreement which have
not theretofore been delivered by the Company pursuant to paragraph 3 above,
and all rights of the Holder in and to such undelivered shares shall be
forfeited; provided, however, the appropriate Board of Directors may, within
120 days after such Termination of Employment, in its sole discretion,
determine whether such former Holder (or his beneficiary, estate or heirs)
shall receive all or any part of the undelivered shares granted pursuant to
this Stock Grant Agreement and whether to impose any conditions in connection
therewith. In addition, each Board of Directors shall from time to time
determine in its sole discretion whether any period of nonactive employment,
including authorized leaves of absence by reason of military or governmental
service, shall constitute Termination of Employment for the purposes of this
paragraph.

         6. The granting of this Stock Grant shall not in any way prohibit or 
restrict the right of the Company to terminate the Holder's employment at any
time, for any reason.

         7. While shares of Common Stock are held in custody for the Holder
pursuant to this Agreement, they may not be sold, transferred, pledged,
exchanged, hypothecated or disposed of by the Holder and shall not be subject
to execution, attachment or similar process.

         8. This Agreement and each and every obligation of the Company
hereunder are subject to the requirement that if at any time the Company shall
determine, upon advice of counsel, that the listing, registration or
qualification of the shares covered hereby upon any securities exchange or
under any state or Federal law, or the consent or approval of any governmental
regulatory body, is necessary or desirable as a condition of or in connection
with the granting hereof or the delivery of shares hereunder, then the delivery
of shares hereunder to the Holder may be postponed until such listing,
registration, qualification, consent or approval shall have been effected or
obtained free of any conditions not acceptable to the Board of Directors of the
Company.

         9. In addition to amounts in respect of taxes which the Company shall
be required by law to deduct or withhold from any dividend payments on the
shares covered hereby, the Company may defer making any delivery of shares
under this Agreement until completion of arrangements satisfactory to the
Company for the payment of any other applicable taxes.

         10. In the event of a "change in control," as that term is defined in
the Plan, then the Holder shall have all the rights specified in Article IX of
the Plan.

         11. Defined words used in this Agreement shall have the same meaning
as set forth in the definitions section or elsewhere in the Plan, the terms and
conditions of which shall constitute an integral part hereof.

         12. Any notice which either party hereto may be required or permitted
to give the other shall be in writing and may be delivered personally or by
mail, postage prepaid, addressed to the Secretary of the Company, 1412 South

         Section 4.02     Additional Rental.

         (a)     For calendar year 1998 and for each calendar year thereafter
Tenant shall pay as additional rental together with all sums other than Annual
Rental payable by Tenant under this Lease (the "Additional Rental") for each
Operating Expense Year (as hereinafter defined) Tenant's Share (as hereinafter
defined) of the increase, if any, in the direct expenses paid or incurred by
Landlord for the operation, repair and maintenance of the Building, Building
Parking Garage, other Common Building Facilities, and the Additional Parking
Area ("Operating Expenses" as more fully defined in Exhibit D).  As of the
Effective Date of this Lease, the total rentable area of the leasable space
within the Building is 515,738 square feet; therefore, as of the Effective Date
of this Lease, the Tenant's Share of Operating Expenses is three point
nine-five percent (3.95%).  Notwithstanding the foregoing, for purposes of
calculating Additional Rental hereunder (i) the Operating Expenses for 1998
shall not exceed four percent (4%) of the Operating Expense Base, and (ii) the
Operating Expenses for each Operating Expense Year following 1998 shall not
exceed four percent (4%) of the Operating Expenses for the immediately
preceding Operating Expense Year  (as limited pursuant to this paragraph
4.02(a)); provided however that such limitation shall apply only to all
Operating Expenses other than the real estate taxes and assessments.  In
calculating the maximum amount of Operating Expenses for Tenants Share, the
amount of actual real estate taxes and assessments shall first be deducted from
Operating Expenses then the four percent (4%) limitation shall be applied to
the remainder and then real estate taxes and assessments shall be added back
and the sum of the above amounts shall be the Operating Expenses used in
determining Tenant's Share of Operating Expenses; provided however that the
amount of real estate taxes and assessments in 1998 shall not be in excess of
ten percent (10%) more than the amount of 1997 taxes and for each year after
1998 shall not be in excess of ten percent (10%) of the amount for the prior
year.  Such Additional Rental shall be payable by Tenant to Landlord as
hereinafter provided.

         (b)     The term "Operating Expense Year" shall mean each calendar
year commencing with the calendar year in which the Term Commencement Date
occurs, falling, in whole or in part, within the term of this Lease.  If a Term
Commencement Date for space leased by Tenant occurs on a date other than
January 1 or the term of this Lease terminates or expires on a date other than
December 31, the Additional Rental for the pertinent Operating Expense Year for
such space shall be prorated based upon the number of days in such Operating
Expense Year occurring after such Term Commencement Date or before the
termination or expiration of the term of this Lease, as applicable.

         (c)     The term "Tenant's Share" shall mean that number, stated above
as a percentage in Section 4.02(a).  In the event of any change in the area of
the Leased Premises or the Building or in the event Tenant is entitled to a
rent abatement for Operating Expenses hereunder as to all or any portion of the
Leased Premises, Tenant's Share shall be adjusted to reflect such change or
event on a prorated, daily basis determined by dividing the number of rentable
square feet in the Leased Premises by the greater of (i) ninety-five (95%)
percent of the number of square feet of rentable area in the Building (as
represented by Landlord in Section 1.01(b)), or (ii) actual number of square
feet of rentable area then leased in the Building.

<PAGE>   7
   
         (d)     The term "Operating Expense Base" shall mean an amount equal
to the product of Operating Expenses for the calendar year 1997 per rentable
square foot and ninety-five (95%) percent of the number of rentable square feet
in the Building (as represented by Landlord in Section 1.01 (b).  On or before
April 1, 1998, Landlord will submit a statement setting forth the computation
of Operating Expenses for the calendar year 1997.

         (e)     Landlord's "Operating Statement" shall mean a statement
setting forth (1) the Operating Expenses for such Operating Expense Year,
showing in detail the amount of each item included in Operating Expenses, (2) a
detailed computation of any Additional Rental for such Operating Expense Year
and (3) a reconciliation of the actual Additional Rental payable by Tenant for
such year with the estimated Additional Rental paid by Tenant for such year.
Each Operating Statement shall be furnished by Landlord to Tenant not later
than April 1 of the calendar year following the Operating Expense Year to which
such statement relates.

         Beginning with January 1, 1998, and for each calendar year thereafter
during the term of this Lease, Landlord shall provide Tenant on or before April
1 of such year with a comparison of the projected Operating Expenses for the
year and the Operating Expense Base and the projected Tenant's Share of any
positive differences between them.  Commencing on the later of (i) the receipt
by Tenant of the Operating Statement for each year or (ii) January 1 of each
year, Tenant shall pay one-twelfth (1/12th) of such positive difference each
month during the year.  If Tenant's Additional Rental for Operating Expenses
reflected in the Operating Statement for any Operating Expense Year are greater
than the amounts actually paid by Tenant for such Operating Expense Year,
Tenant shall pay Landlord such difference within thirty (30) days of receipt of
the Operating Statement for such Operating Expense Year.  If Tenant's
Additional Rental for Operating Expenses reflected in the Operating Statement
for any Operating Expense Year are less than the amounts actually paid by
Tenant for such Operating Expense Year, such difference shall be credited to
Tenant's next payment(s) of Annual Rental and/or Additional Rental, unless the
term has expired, in which event such difference shall be paid by Landlord to
Tenant within thirty (30) days of delivery of the Operating Statement (net of
any sums otherwise owed by Tenant to Landlord).

         (g)     In no event shall Tenant's Annual Rental be reduced, nor shall
Landlord owe any amount to Tenant, if, for any reason, Operating Expenses for
any Operating Expense Year are less than the Operating Expense Base.

         (h)     Landlord shall permit Tenant, at any reasonable time after
reasonable notice, to inspect and do a complete audit at Tenant's sole expense,
but only with the use of a "Big Six" accounting firm, of all of the books of
accounts and records of Landlord to the extent reasonably required to establish
Operating Expense.  Tenant may not request such an audit more than once per
calendar year.  If Tenant shall ask for an audit to be made, and if Operating
Expenses for any period shall be found to be overstated or understated, then
Landlord shall pay Tenant the amount of overpayment, or Tenant shall pay to
Landlord the amount of the underpayment, as the case may be, together with
interest thereon at the rate specified in Section 8.02(b) of this Lease, from
the date of such overpayment or underpayment to the date the overpayment or
underpayment is refunded or





                                      -7-

paid. Tenant's right to make such an audit with respect to any calendar year
shall expire twelve (12) months after Landlord's Operating Statement for the
calendar year shall have been delivered to Tenant, and each such Operating
Statement shall be final and binding on Tenant and shall, as between the
parties, be conclusively deemed correct, at the end of such twelve (12) months,
unless prior thereto Tenant has served Landlord with a notice challenging the
accuracy of same.

         Section 4.03     Real Estate Taxes, Assessed Valuation.

         (a)     If Landlord fails to pay any real estate tax or assessment
includable in Operating Expenses prior to the time that any penalty or interest
may be charged, any penalty or interest levied shall not be included by
Landlord in Operating Expenses for purposes of calculating Tenant's Additional
Rental.

         (b)     Landlord may petition for reduction of the assessed valuation
of the Building and the land comprising The Texaco Building Complex, claim a
refund of real estate taxes or assessments or otherwise challenge the validity

shall be in accordance with Renewal Term Rental Rate as indicated in Exhibit C.


                            ARTICLE FIVE - SERVICES

         Section 5.01     Standard of Operations.

         (a)     Landlord shall at all times operate and maintain the Building
in accordance with a standard at least as high as that customarily followed in
the operation and maintenance of office buildings similar to the Building and
with similar tenants in the vicinity of the Building ("Comparable Buildings")
and, without limiting the foregoing, shall provide the specific facilities,
utilities and services set forth in this Article.

         (b)     The office space in the Building, other than the space
occupied by Tenant, shall be leased only to tenants who are similar in
character to those found in Comparable Buildings.  Ground floor retail space,
if any, may be leased to commercial occupants of the following character:
banks, restaurants, department stores and retail merchants and other tenants
found in office and retail space in Comparable Buildings.  Landlord may (but
shall not be obligated to) lease space in the Building to a first-class club
facility.

         Section 5.02     Heating, Ventilating and Air Conditioning.

         (a)     Landlord shall provide a heating, ventilating and air
conditioning system ("HVAC") meeting the requirements of Exhibit F. Landlord
shall furnish HVAC services meeting the





                                      -8-
    
<PAGE>   9
   
requirements of Exhibit F in season as required for Tenant's comfortable use
and normal occupancy of the Leased Premises, from 7:00 a.m. to 6:00 p.m.
(Landlord shall turn on the HVAC system of the Building by 6:00 a.m. on
Tenant's floors to enable the comfortable use and normal occupancy of the
Leased Premises to be met by 7:00 a.m.) Mondays through Fridays and from 8:00
a.m. to 1:00 p.m. on Saturday.  For purposes of this Lease, holidays shall be
indicated in writing by Landlord annually (the "Building Holiday Schedule").
Tenant shall make arrangements for building services at least sixty (60) days
in advance if the Building is scheduled to be closed.

         (b)     Landlord shall, upon reasonable advance notice from Tenant,
furnish Tenant HVAC services at any time or times other than the regular hours
specified above in accordance with the schedule attached hereto as Exhibit 1.

         (c)     For HVAC and humidity control systems requiring special
operating hours or other conditions which necessitate the use of self-contained
units (the "Special Systems"), Landlord shall furnish electrical power to
Tenant for Tenant's use in installing and operating, at Tenant's expense, one
or more Special Systems.  Tenant shall bear any extra expense incurred by
Landlord in furnishing such power from the Building's system or in expanding
the Building's system, if necessary, to provide such electrical power,
including the cost to Landlord of providing direct and separate metering if
either Landlord or Tenant requests separate metering.  Such expansion of the
Building's system, if necessary, shall be subject to the approval of Landlord,
which shall not be unreasonably withheld or delayed.  Landlord shall review
Tenant's HVAC plans prior to construction of Tenant's interior improvements and
notify Tenant if Landlord will charge Tenant for the installation and or use
any Special Systems.

         Section 5.03     Electrical Service.

         (a)     Landlord shall provide an electrical distribution system for
the Building meeting the requirements of Paragraph II of Exhibit F.  Landlord
shall cause to be furnished and pay for all electricity used in the Leased
Premises or in operating any and all facilities serving the Leased Premises
(the cost of same to be Operating Expenses); provided, however, that Tenant
shall bear any extra expense incurred by Landlord in furnishing electric power
in excess of the normal office use which may be required for use by Tenant for
electronic data processing equipment (including computers), if furnishing such
excess power is reasonably feasible, given the reasonable needs of the Building
and other occupants, including the cost to Landlord of providing direct and
separate metering if either Landlord or Tenant requests separate metering.  If
direct and separate meters are not used, the amounts chargeable to Tenant under
the preceding provision shall be Landlord's average cost of electric power
multiplied by Tenant's excess usage, as reasonably determined by Landlord's
professional engineer.  Landlord shall review Tenant's electrical plans prior
to initial installation and advise Tenant whether excess capacity is required
to be installed at Tenant's expense and whether Landlord anticipates that
Tenant's usage shall exceed the amount for normal office use.

         (b)     Landlord will notify Tenant at least seventy-two (72) hours in
advance of any planned shut down of the electrical system for repairs or
maintenance.  Landlord will attempt to schedule





                                      -9-
    
<PAGE>   10
   
such shut downs for weekends starting on Friday evenings.  Any such shut downs
shall not entitle Tenant to any abatement of rent during the scheduled shut
down period or be construed as an interruption of services under Section 5.08
of this Lease.

         Section 5.04     Elevators.

         (a)     Landlord shall provide passenger elevators to serve the Leased
Premises.  The passenger elevators shall generally be available during all
working hours of all working days, and, at all other times, there shall be at
least one passenger elevator available to serve the Leased Premises subject to
events beyond Landlord's reasonable control and emergencies which may arise.
In the event of such interruption, Landlord shall, as promptly as is practical
under the circumstances, commence to use all reasonable efforts to cause such
service to be reinstated as soon as is practical.

         (b)     There is a designated freight elevator in the Building.
Tenant shall provide Landlord with twenty-four (24) hours' advance notice of
its need for a freight elevator and Landlord shall endeavor to make the freight
elevator available to Tenant.  Tenant's use of the freight elevator is limited
by the Building's Rules and Regulations, which are subject to change.  Failure
to provide said notice shall relieve Landlord of its obligation to provide a
dedicated freight elevator.

         Section 5.05     Light Bulbs and Water.  Landlord shall furnish and/or
install as an Operating Expense (a) all initial and replacement fluorescent and
incandescent light bulbs and ballast in the Leased Premises, Common Building
Facilities and Building Parking Garage, provided that they are the Building's
standard bulbs and ballasts.  Tenant will comply with all of Landlord's
standards for energy efficient lighting fixtures; provided however if Landlord
is required to make replacement of lighting fixtures in the Premises by reason
of legal requirements, such replacement shall be at Landlord's expense.
Landlord shall furnish water, including chilled and heated water, at those
points of supply provided for general use of all tenants in the Building as
required for lavatory and drinking purposes and such other uses as are
permitted pursuant to Section 7.01. The fire stand pipe water system shall
comply with the National Fire Protection Agency "NFPA Code" and applicable
local laws.

         Section 5.06     Access Control.

Building and Building Parking Garage.  Such access control may include
electronic access control to the Building and Leased Premises.

or burglary, or for damages or injuries caused by the entry of unauthorized
persons to the Building, Building Parking Garage, the Leased Premises or other
portions of the Building; provided however that Landlord shall, subject to
Section 9.02 hereof, remain liable for damages or injuries arising directly
from the gross negligence of Landlord.  If installed, Landlord's access control
system shall comply with the requirements of all Applicable Laws.

         (c)     Tenant, at its expense and with the prior written approval of
Landlord, which approval shall not be unreasonably withheld or delayed, may
install such additional safety and security systems or devices within or
controlling access to the Leased Premises (but not in any lobbies or other
common areas), including, without limitation, smoke detectors, electronic
security devices and auxiliary emergency electric power supplies, as Tenant may
deem reasonably appropriate.  Tenant shall have the right by installation of a
card or key system, to control access from all public elevators to floors
wholly occupied by Tenant; provided that Tenant's use of such system shall not
interfere with Landlord's obligations to provide services or perform any work
under this Lease; and provided, further, that, Landlord shall have reasonable
access to the Leased Premises in emergencies and provided that such system does
not interfere with the proper operating of the elevator system or require the
Landlord to incur additional costs to retrofit or maintain the elevators in
order to accommodate such a system.

         (d)     Tenant, at its expense, may install and operate a cardkey or
similar security system for the Leased Premises so long as it does not
interrupt ingress and egress of other tenants on multi-tenant floors.

         (e)     Any additional safety or security systems installed by Tenant
shall be compatible with Landlord's security and safety systems, programs and
procedures and shall comply with all Applicable Laws.

         Section 5.07     Janitorial Services.

         (a)     Landlord shall provide, as an Operating Expense the cleaning
and janitorial services ("Janitorial Services") and window cleaning services
set forth in Exhibit G hereto.

         Section 5.08     Interruption of Services.

         (a)     If, for any reason within Landlord's reasonable control there
is a failure to furnish the facilities, utilities or services specified in this
Article which are essential for Tenant's beneficial occupancy of the Leased
Premises or to provide parking spaces required by Article Six and, after
written notice thereof by Tenant to Landlord and to any holder of a First
Mortgage for which Tenant has been provided a notice address, Landlord does not
remedy same within thirty (30) days following delivery of such written notice
(provided as to matters which cannot reasonably be remedied within thirty (30)
days, Landlord shall not be deemed to be in default of its obligations, and
Tenant shall have no remedy hereunder except as may be provided in Section
5.08(d), provided Landlord has commenced such cure within said thirty (30) day
period and thereafter diligently prosecutes such cure to completion).  If
Landlord is in default after the applicable cure period, then Tenant shall, if
it is not then in default of any of its obligations under this Lease, have the
option to provide such facilities, utilities or services for its own account
until Landlord remedies the default and performs such obligations in accordance
with this Lease.  If any interruption of services shall continue for more than
sixty (60) days, Tenant may, by written notice to Landlord given at any time
prior to the resumption of service to a reasonable level, terminate this Lease,
and, upon giving such notice, this





                                      -11-
    
<PAGE>   12
   
Lease shall terminate and expire on the date set forth in such notice, which
date shall not be more than ninety (90) days after the date of such notice.

         (b)     In addition to Tenant's self-help remedies described in
subsection (a) above, if for any reason within Landlord's reasonable control
there is a failure to furnish the facilities, utilities or services required to
be furnished by this Lease and such failure results in an imminent threat to
persons, Tenant's property or Tenant's business, Tenant may, after providing
Landlord with such notice and the first right to remedy such failure as is
practical under the circumstances, provide for its own account such facilities,
utilities or services to the extent necessary to remove the threat to persons
or property.

         (c)     Any reasonable sums expended by Tenant in exercising its
remedies described in Sections 5.08(a) or 5.08(b) above shall be reimbursed by
Landlord within sixty (60) days of Tenant's invoice therefore together with
invoices and paid receipts and other reasonable evidence of such costs (a copy
of same shall be simultaneously delivered by Tenant to any holder of a First
Mortgage for which Tenant has been given a notice address).

         (d)     If any impairment or cessation of Building Services pursuant
to Section 5.08(a) or Section 5.08(b) renders part or all of the Leased
Premises unusable for the normal conduct of Tenant's business for more than
five (5) consecutive business days, rent shall thereafter abate as to the
portion of the Leased Premises rendered unusable until such service is
reinstated so that Tenant's Leased Premises are again useable for the normal
conduct of Tenant's business.

         (e)     The remedies set forth in subsections (a)-(d) above shall be
Tenant's exclusive remedies for interruption of Building Services resulting
from Landlord's negligent or wrongful acts or omissions.  If an impairment or
cessation of Building Services results from the failure of any utility company
or other third party service provider to furnish such services, or other event
beyond Landlord's reasonable control, Landlord shall have no liability to
Tenant under this Lease and, except as provided in the next sentence, rent
shall not abate, provided Landlord promptly notifies the service provider of
such impairment or cessation and thereafter employs all reasonable efforts to
cause such services to be reinstated.  If such impairment or cessation of
Building Services resulting from the failure of any utility company or other
third party service provider to furnish such services or other events beyond
Landlord's reasonable control renders part or all of the Leased Premises
unusable for the normal conduct of Tenant's business for more than five (5)
consecutive business days, rent shall thereafter abate as to the portion of the
Leased Premises rendered unusable until such service is reinstated so that
Tenant's Leased Premises are again useable for the normal conduct of Tenant's
business.

         Section 5.09     Personnel.  Landlord shall employ and/or contract
with persons of sufficient number and experience to maintain the Building and
Common Building Facilities and to perform the services within its control which
Landlord is required to perform under this Lease.

                 (ii)     Employers' Liability Insurance protecting Tenant

                          arising out of the master-servant relationship with a
                          limit of not less than $1,000,000;

                 (iii)    Commercial General Liability Insurance including

                          described above with minimum limits of $1,000,000 in
                          excess of specified limits;

                 (vi)     All-Risk Property Insurance for the ninety (90%)
                          percent replacement value of any leasehold
                          improvements, additions, alterations and/or
                          installations made by tenant and for all contents.

         (b)     Landlord shall maintain insurance coverage applicable to the
Texaco Building Complex similar to the coverage required to be maintained by
Tenant in Section 5.10 above including, without limitation All-Risk Property
insurance for ninety percent (90%) of replacement value on the Texaco Building

         (c)     Prior to commencement of the Lease, a certificate evidencing
the required coverage shall be delivered by each party to the other, naming the
other as an additional insured as respects liability coverages.  This
certificate shall provide that any change restricting or reducing coverage or
the cancellation of any policies under which certificates are issued shall not
be valid until the other party has received 30 days' written notice of such
change or cancellation.  Further, the certificate shall state that the
insurance is primary coverage and not concurrent or excess over other valid
insurance which may be available.  The Workers' Compensation policy shall be
endorsed to provide

waiver of subrogation rights in favor of the other party.  Such insurance may
be carried under a blanket policy covering the Leased Premises and other

other party as an additional insured, (ii) specifically referencing the Leased
Premises on the Texaco Building Complex; and (iii) guaranteeing a minimum limit
available equal to the limits of liability required under this Lease.

         (d)     Tenant agrees to comply with all terms of the insurance
contracts referenced in this section.  Failure of Tenant to keep the required
insurance policies in full force and effect during the term of this Lease and
during any extensions, shall constitute a breach of this Lease and Landlord
shall have the right, in addition to any other rights, to cancel and terminate
this Lease without further cost to Landlord.  Nothing contained in these
provisions relating to coverage and amounts set out herein shall operate as a
limitation of tenant's liability in tort or contract under the terms of this
Lease.

         (a)     Tenant acknowledges that Landlord has made available at
Landlord's office certain environmental reports and surveys of the Building,
including asbestos surveys and asbestos remediation certifications and current
activities.  A list of the environmental reports and surveys are listed in
Exhibit J - Environmental, which is made a part of this Lease.  The purpose of
providing the reports and surveys listed in Exhibit J is to indicate the
presence or absence of asbestos.  Landlord makes no representations or
warranties whatsoever to Tenant regarding:

         The materials listed in Exhibit J and made available to Tenant for its
review (Landlord has informed Tenant that the materials listed in Exhibit J are
not a comprehensive hazardous substance survey of the Building for all forms of
hazardous or toxic materials, including, but not limited to, asbestos
containing hazardous materials, and can not be relied upon as a representation
that there are no hazardous or toxic materials at the Building, whether

informational purposes only.  Prior to commencement of interior improvements
made prior to the Term Commencement Date by Tenant, Tenant shall have ten (10)
days to engage such specialists and to make studies and investigations and such
tests and surveys of the Leased Premises from an environmental standpoint as
Tenant deems necessary and appropriate.  If Tenant determines from the
resulting study, test, investigation or survey as conducted by an independent
third party engineer experienced in such matters that the Leased Premises are
contaminated or otherwise contain hazardous materials and adversely affect
Tenant's use and or occupancy of the Leased Premises and cannot be controlled
or contained in a manner reasonably acceptable to Tenant, then Tenant shall
have a one-time right exercisable within five (5) days of receiving such
results to notify Landlord in writing and terminate this Lease, otherwise such
right of termination shall be deemed waived for all purposes hereunder.

         Tenant shall furnish Landlord with a complete and legible copy of any
study, report, test, survey or investigation performed by or on behalf of
Tenant at any time involving the Leased Premises and shall fully restore all
improvements where samples were taken or work performed and repair all damage
resulting from any of the same and shall indemnify and hold Landlord harmless
from any and all claims, actions, liabilities, damages, losses, injuries or
deaths in connection with or arising out of or from any inspection, sampling or
similar or dissimilar activity conducted by Tenant, Tenant's agents or
contractors at the Leased Premises for hazardous or toxic materials, whether
under this section or otherwise under or in connection with this Lease.

         (b)     Landlord and its agents shall have the right to periodically
inspect, take samples for testing and otherwise investigate the Leased
Premises, at times reasonably acceptable to Tenant, for the presence of
hazardous or toxic materials.  Landlord's inspections, sampling or testing will
not unreasonably interfere with Tenant's use of the Leased Premises and
Landlord shall fully restore all improvements where samples were taken or work
performed and repair all damage resulting from any of the same and shall
indemnify and hold Tenant harmless from any and all claims, actions,
liabilities, damages, losses, injuries or deaths in connection with or arising
out of or from any inspection, sampling or similar or dissimilar activity
conducted by Landlord, Landlord's agents or contractors at the Leased Premises
for hazardous or toxic materials, whether under this section or otherwise under

         Landlord shall not knowingly dispose of at the Leased Premises, any
toxic or hazardous materials in concentration or levels sufficient that by then
applicable governmental standards cause the specific material so identified to
be classified or identified as toxic or hazardous materials and shall otherwise
deal with all toxic or hazardous materials at the Leased Premises in a manner
that will not adversely affect Tenant's access, use or occupancy of the Leased
Premises.  Any remediation or control at the Leased Premises will be in
accordance with all applicable governmental laws, rules, and regulations.  If
Landlord or Tenant ever have knowledge of the presence in the Leased Premises
of such toxic or hazardous materials which affect the Leased Premises, the
party having knowledge shall notify the other party thereof in writing promptly
after receiving such knowledge.  For purposes of this Lease, hazardous or toxic
materials shall mean hazardous or toxic chemicals or any materials or wastes
containing hazardous or toxic chemicals or materials at levels or content which
causes such materials or wastes to be classified as hazardous or toxic as then
prescribed by the then current levels or contents as set from time to time by
EPA or OSHA or as identified under 29-CFR-1910 or 29-CFR-1925 or other
applicable governmental laws, rules and regulations.

         (d)     If Tenant or its employees, agents or contractors shall ever
violate the provisions of Paragraph a or c above (that apply to Tenant
regarding toxic or hazardous materials), or if Tenant's acts, negligence,
breach of this provision or business operations directly and materially expand
the scope of or materially worsen any contamination from toxic or hazardous
materials installed or introduced by Tenant, then Tenant shall clean up, remove
and dispose of the material causing the violation, in compliance with all
applicable governmental standards, laws, rules and regulations and repair any
damage to the Leased Premises or any part of the Building or The Texaco
Building Complex within such period as may be reasonable under the
circumstances after written notice by Landlord, provided that such work shall
commence not later than fifteen (15) days from such notice and be diligently
and continuously carried to completion by Tenant or Tenant's designated
contractors.

         Tenant shall notify Landlord of its method, time and procedure for any
clean-up or removal of toxic or hazardous materials under this provision; and
Landlord shall have the right to require reasonable changes in such method,
time or procedure or to require the same to be done after normal business hours
or when the Building or The Texaco Building Complex is otherwise closed (i.e.,
weekends and holidays).

         (e)     Landlord represents and warrants that the Leased Premises, the
Building and The Texaco Building Complex are in substantial compliance with all
federal, state and local laws relating thereto (including, without limitation,
all laws relating to health or the environment) sufficient to afford Tenant's
quiet and save enjoyment of the Leased Premises.  If Landlord or its employees,
agents or contractors shall ever violate the representations contained in this
Paragraph (e), or if Landlord's acts, negligence or business operations
directly or materially expand the scope of or materially worsen any
contamination from toxic or hazardous materials, then Landlord shall clean up,
remove and dispose of the material causing the violation, in compliance with
all applicable governmental standards, laws, rules and regulations and repair
any damage to the Leased Premises or any part of the Building or The Texaco
Building Complex within such period as may be





                                      -17-
    
<PAGE>   18
   
reasonable under the circumstances, and such remedial activities shall be
diligently and continuously carried to completion by Landlord or Landlord's
designated contractors.

         Landlord shall notify Tenant of its method, time and procedure for any
clean-up or removal of toxic or hazardous materials in the Leased Premises, and
Tenant shall have the right to request reasonable changes in such method, time
or procedure and to require the same to be done after normal business hours or
when the Tenant is closed for business (i.e., weekends and holidays) if such
creates a disruption to Tenant's operations or constitutes a potential risk to
public health or safety.

         Section 7.03     Access.  Subject to events beyond Landlord's
reasonable control and emergencies which may arise, Tenant, its permitted
subtenants and their employees, licensees and guests, shall have access to the
Leased Premises at all times, 24 hours per day, every day of the year, except
if the building is closed due to an emergency or the facility is closed by
governmental order.

         Section 7.04     Use of the Common Areas for Certain Purposes.
Tenant, subject to the prior written consent of Landlord, not to be
unreasonably withheld, and subject to scheduling as to date and time when the
common areas are not otherwise in use, shall have the nonexclusive right to use
the common areas and other public portions of the Building to present public
events and other exhibits, provided same do not impair the character the
dignity of the Building or interfere with other tenants in the Building.
Landlord reserves the right to restrict or deny the use of the lobby.

         Section 7.05     Building Directory.  Landlord, at its expense, shall
maintain a Building directory in the lobby of the Building for all tenants of
the Building.  Landlord shall also provide floor signage in the elevator lobby
of Tenant's floor at Tenant's expense.  The exact size, location, and design to
be approved by Landlord.  Landlord shall list Tenant on such directory at no
charge for the initial listing, such initial listings on the directory as
Tenant shall reasonably require up to Tenant's prorata share of the available
listings.  All changes, additions and subtractions to and from Tenant's initial
listings shall be at Tenant's sole expense, and Tenant shall pay Landlord's
cost for the same.  Landlord reserves the right to modify or replace the
directory at any time in the future in its sole discretion.

<PAGE>   19
   
         Section 8.02     Tenant's obligations.

         (a)     Tenant shall maintain the Leased Premises (except the base
building systems contained therein), including all of Tenant's additions,
alterations, installations, improvements and trade fixtures, all special HVAC
equipment and other special facilities installed by or on behalf of Tenant, and
all of Tenant's property within the Leased Premises and shall repair any and
all damage caused by it to the Building or the Leased Premises, ordinary wear
and tear, damage by fire or other casualty and damage caused by others for whom
Tenant is not responsible excepted.  Upon termination of this Lease, Tenant
shall surrender and deliver up the Leased Premises in the same condition in
which existed at the commencement of this Lease, except for ordinary wear and
tear, Tenant's alterations, additions, installations and improvements, repairs
and maintenance assumed by Landlord, damage arising from fire or other casualty
and damage caused by others for whom Tenant is not responsible and which damage
Tenant is otherwise not obligated to repair or restore under this Lease.

         (b)     If Tenant fails to perform any maintenance or repair required
under this Section 8.02, Landlord may, following thirty (30) days' written
notice to Tenant, perform the same and Tenant shall reimburse Landlord for the
reasonable cost of such maintenance and/or repair within thirty (30) days of
Landlord's invoice therefor, together with invoices and paid receipts and other
reasonable evidence of such costs.  If such amounts are not paid by Tenant
within the thirty (30) day period, interest shall accrue on such sums based on
Chase Manhattan Bank's New York published prime rate or in the event Chase
Manhattan Bank no longer publishes a prime rate, another major bank substituted
by Landlord, plus 150 basis points (the "Default Rate").  In addition, if
Tenant's failure to maintain or repair causes an imminent threat to persons or
property, Landlord may, after providing Tenant with such notice as is
reasonable under the circumstances, perform such maintenance or repair and
Tenant shall reimburse Landlord for the reasonable cost of such maintenance
and/or repair within thirty (30) days of Landlord's invoice therefor, together
with invoices and paid receipts and other reasonable evidence of such costs.
If such amounts are not paid by Tenant within the thirty (30) day period,
interest shall accrue on such sums until paid at the Default Rate.

                     ARTICLE NINE - FIRE AND OTHER CASUALTY

         Section 9.01     Damage or Destruction.

         (a)     If the Building or any part thereof should be destroyed or
damaged by fire or other casualty during the term of this Lease, then (unless
this Lease is terminated by Landlord or Tenant as hereinafter provided)
Landlord shall within sixty (60) days of the date of the casualty, proceed to
reconstruct, restore and repair the Building and the base building systems and
Building standard improvements contained in the Leased Premises, as the case
may be, to a condition substantially equivalent to their former condition.  If
Landlord does not so commence such restoration or, if having done so, does not
proceed with reasonable diligence until same are restored, then upon receipt of
written notice to Landlord and any holder of a First Mortgage for which Tenant
has been given a notice address from Landlord, Landlord or such First Mortgage
holder shall have twenty (20) days





                                      -19-
    
<PAGE>   20
   
to so commence or so proceed.  If Landlord fails and the First Mortgage holder
also fails to commence or proceed with such action within this period of time,
Tenant, as its sole remedy for such failure, may forthwith terminate this
Lease, effective as of the date of the casualty.

         (b)     Notwithstanding anything seemingly to the contrary in Section
9.01 (a), Landlord's obligation to restore shall be limited to the insurance
proceeds it receives, plus applicable deductibles; provided however, such
limitation shall not impair or limit Tenant's right to terminate the Lease for
Landlord's failure to timely commence or to complete restoration as provided in
Section 9.01 (a).

         (c)     Commencing with the date of such damage, the Rent provided for
herein shall abate prorata to the extent that, and for so long as, any portion
of the Leased Premises is not reasonably usable; provided however that upon
substantial completion by Landlord of its restoration work Rent shall commence
on the earlier of the reasonable time thereafter required for Tenant to
substantially complete its restoration work under Section 9.01 (e) or sixty
(60) days after reasonable ingress and egress has been provided and reasonably
sufficient parking has been provided (which may be provided by shuttle bus or
other reasonable means).

         (d)     It is agreed that if the Building is totally destroyed by any
cause or is so substantially destroyed that reconstruction would require more
than one hundred eighty (1 80) days, as reasonably estimated by Landlord's
architect or contractor, either Landlord or Tenant may elect to terminate this
Lease by giving the other party written notice of such election within thirty
(30) days after the giving of the notice from Landlord hereinafter provided.
Such termination shall be effective as of the date of such election.  In the
event of any substantial casualty, Landlord shall within thirty (30) days
thereafter, give Tenant written notice of the estimated time required to repair
the same as reasonably estimated by Landlord's contractor or architect.

         (e)     For any casualty to the Leased Premises only, or any casualty
to the Building and Leased Premises in which Landlord is obligated to restore
the Building or otherwise elects to restore the Building, Tenant shall promptly
commence and diligently prosecute to completion the restoration of the
leasehold improvements, alterations, installations, additions and trade
fixtures which are damaged or destroyed to a completion substantially
equivalent to their former condition.

         Section 9.02     Waiver of Subrogation Rights.  Provided that
Landlord's right of full recovery under its policy or policies aforesaid is not
adversely affected or prejudiced thereby, Landlord hereby waives any and all
right of recovery which it might otherwise have against Tenant, its servants,
agents and employees, for loss or damage occurring to the Building, the Parking
Garage and the fixtures, appurtenances and equipment therein, to the extent the
same is covered by Landlord's insurance, notwithstanding that such loss or
damage may result from the negligence or fault of Tenant, its servants, agents
or employees.  Provided that Tenant's right of full recovery under its
aforesaid policy or policies is not adversely affected or prejudiced thereby,
Tenant hereby waives any and all right of recovery which it might otherwise
have against Landlord, its servants, and employees and against every other
tenant in the Building and/or the Parking Garage who shall have





                                      -20-
    
<PAGE>   21
   
executed a similar waiver as set forth in this Section 9.02 for loss or damage
to Tenant's furniture, furnishings, fixtures and other property removable by
Tenant under the provisions hereof to the extent that same is covered by
Tenant's insurance required under this Lease, notwithstanding that such loss or
damage may result from the negligence or fault of Landlord, its servants,
agents or employees, or such other tenant and the servants, agents or employees
thereof.

         Landlord and Tenant hereby agree to advise the other promptly if the
clauses to be included in their respective insurance policies above cannot be
obtained on the terms hereinbefore provided and thereafter to furnish the other
with a certificate of insurance or copy of such policies showing the naming of
the other as an additional insured, as aforesaid.  Landlord and Tenant hereby
also agree to notify the other promptly of any cancellation or change of the
terms of any such policy which would affect such clauses or naming.  All such
policies which name both Landlord and Tenant as additional insureds shall, to
the extent obtainable, contain agreements by the insurers to the effect that no
act or omission of any additional insured will invalidate the policy as to the
other additional insureds.


                            ARTICLE TEN - LIABILITY

         Section 10.01    Waiver.  To the extent permitted by law, Tenant
releases the Landlord, holders of any Mortgage on the Texaco Building, property
manager and their respective partners, employees, officers, directors and
agents ("Indemnitees") from, and waives all claims for, damage to person or
property sustained by the Tenant, resulting from any accident or event in or
about the Texaco Building Complex, or directly or indirectly from any act or
neglect of any tenant or occupant of the Building and the Parking Garage or of
any other person, including the Indemnitees, except where such results from the
gross negligence of an Indemnitee in which event such Indemnitee and Landlord
shall be liable to Tenant, subject to the provisions of Section 9.02.

         Section 10.02    Indemnity by Tenant.  To the extent permitted by law,
Tenant agrees to indemnify, protect, defend and hold the Indemnitees harmless
against any and all actions, claims, demands, costs and expenses, including
reasonable attorney's fees and expenses for the defense thereof, arising from
Tenant's breach or default on the part of Tenant in the performance of any
covenant or agreement on the part of Tenant to be performed pursuant to the
terms of this Lease, in or about the Leased Premises and the Building,
Additional Parking Area and The Texaco Building Complex (subject to Section
9.02 and excluding actions and claims arising from the gross negligence of the
Indemnitees), but only to the extent required by this Lease or to the extent of
Landlord's liability, if any, in excess of amounts, if any, paid to Landlord
under insurance covering such claims or liabilities.  In case of any action or
proceeding brought against the Indemnitees by reason of any such claim, upon
notice from Landlord, Tenant covenants to defend such action or proceeding by
counsel reasonably satisfactory to Landlord.

         10.03   Indemnity by Landlord.  Landlord agrees to indemnify, protect,
defend and hold the Tenant, Tenant's employees, officers, directors, and
agents, (hereinafter the "Tenant Indemnitees")





                                      -21-
    
<PAGE>   22
   
harmless against any and all actions, claims, demands, costs and expenses,
including reasonable attorney's fees and expenses for the defense thereof,
arising from any breach or default on the part of Landlord in the performance
of any covenant or agreement on the part of Landlord to be performed pursuant
to the terms of this Lease, in or about the Building, Additional Parking Area,
The Texaco Building Complex (subject to Section 9.02 and excluding actions and
claims arising from the gross negligence of Tenant's Indemnitees), but only to
the extent required by this Lease or to the extent of Tenant's liability, if
any, in excess of amounts, if any, paid to Tenant under insurance covering such
claims or liabilities.  In case of any action or proceeding brought against the
Tenant Indemnitees by reason of any such claim, upon notice from Tenant,
Landlord covenants to defend such action or proceeding by counsel reasonably
satisfactory to Tenant.


                   ARTICLE ELEVEN - ALTERATIONS AND FIXTURES

         Section 11.01    Alterations by Tenant.

         (a)     Tenant may make such alterations in or additions to the Leased
Premises as it shall from time to time elect to make; provided, however, that
any material alteration in or addition to the Leased Premises (it being
expressly agreed that decorations, substitutions and nonstructural changes
which are not visible from the exterior of the Building or Leased Premises and
do not adversely affect the base building HVAC or mechanical, electrical or
plumbing systems shall not be deemed material) shall be subject to the prior
written consent of Landlord in each instance, which consent shall not be
unreasonably withheld or delayed, except as to changes visible from the
exterior of the Building or changes which impair or cause load design problems
for the structural, HVAC, mechanical, electrical or plumbing systems of the
Building, as to which Landlord may withhold consent in its sole discretion.
Subject to the approval of Landlord, which will not be unreasonably withheld,
Tenant may use contractors of its own selection and there shall be no overhead
or supervision fees to Landlord for any such work.  Except for the initial
installation of Tenant's improvements which are to be funded by Tenant
Improvement Allowance,  Tenant shall reimburse Landlord for any reasonable
out-of-pocket fees or expenses paid to third-party architects, engineers,
consultants and/or other professionals in evaluating any alteration requested
by Tenant pursuant to this Section 1 1.01.

         (b)     All alterations or additions made by Tenant in the Leased
Premises shall be constructed and completed in a good and workmanlike manner at
Tenant's expense by contractors approved by Landlord, such approval not to be
unreasonably withheld or delayed.  Tenant shall furnish to Landlord in advance
the plans and specifications for and any other information which Landlord may
reasonably request pertaining to such alterations or additions.  Tenant shall
obtain all necessary governmental permits, licenses and approvals and shall
comply with all Applicable Laws and the requirements of Landlord as to work
schedule, noise abatement, safety, security, elevator access, trash removal and
other activities to minimize disruption and annoyance to other tenants in the
Building.  Upon termination of Tenant's lease of any floors in which Tenant has
installed special cabling and systems and/or other additions or alterations,
Landlord may require Tenant to restore at





                                      -22-
    
<PAGE>   23
   
Tenant's sole cost and expense such portions of the Leased Premises to their
original condition prior to the termination or expiration of this Lease or the
partial termination of this Lease, normal wear and tear excepted.

         (c)     Tenant shall pay all taxes and assessments levied with respect
to Tenant's trade fixtures and personal property in the Leased Premises and
shall reimburse Landlord for any portion of the ad valorem taxes and
assessments levied against the equitably attributable to the cost of such trade
fixtures, and personal property.

         Section 11.02    Tenant's Property.

         (a)     Tenant, at its expense, may, at any time and from time to
time, install in and remove from the Leased Premises its trade fixtures,
equipment, movable partitions, walls and wall systems (excluding the Virginia
Panel Wall System which shall remain the property of Landlord), furniture and
furnishings, provided such installation or removal is accomplished without
material damage to the Leased Premises or the Building and Tenant promptly
repairs any damage thereto.

         (b)     Upon the expiration of this Lease, Tenant shall remove all of
Tenant's property not  affixed to the Building walls, floors and ceilings which
can be removed without material damage to the Leased Premises or the Building
and Tenant promptly repairs any damage thereto.  If Tenant fails to remove any
personal property of Tenant that Tenant may remove upon the termination of this
Lease, any such property not so removed shall, at Landlord's election, become
the property of Landlord or be removed by Landlord at Tenant's expense.


                         ARTICLE TWELVE - CONDEMNATION

         Section 12.01    Total Taking.  If all of the Building or the Leased
Premises shall be taken by condemnation or in any other manner for any public
or quasi-public use or purpose (other than for temporary use or occupancy), the
term of this Lease shall terminate as of the date of vesting of title (the
"Date of the Taking"), and, subject to a proration and apportionment of Annual
Rental and proration, apportionment and reconciliation of Additional Rental and
other sums due hereunder as of the Date of the Taking, no further rent shall be
due hereunder.

         Section 12.02    Partial Taking.  If a part of the Leased Premises
shall be so taken, then Landlord shall give Tenant prompt written notice
thereof and the part so taken shall no longer constitute part of the Leased
Premises, but this Lease shall continue in force and effect as to the part not
so taken; provided, however, that Tenant may elect to terminate this Lease (a)
if a partial taking is more than ten percent (10%) of the Leased Premises
(unless Landlord is able to provide alternate premises in the Building
reasonably acceptable to Tenant for the normal conduct of Tenant's business for
the portion of the Leased Premises which was taken), (b) if, in the good faith,
reasonable judgment of Tenant, the remaining portion of the Leased Premises
cannot be economically and practicably used by Tenant for the conduct of its
business or (c) if a partial taking has a material and





                                      -23-
    
<PAGE>   24
   
adverse effect upon the means of access to the Leased Premises or the entrances
or lobbies of the Building, thereby rendering the Leased Premises unfit for the
normal conduct of Tenant's business, unless Landlord shall have provided
reasonable substitutes therefor.  Tenant shall give notice of any election to
terminate to Landlord not later than sixty (60) days after notice of such
taking is given by Landlord to Tenant.  Upon the date specified in Tenant's
notice (which shall be a date as soon thereafter as is practical for Tenant to
relocate from the Building, but in no event more than one hundred eighty (180)
days thereafter), the term of this Lease shall terminate and, subject to a
proration and apportionment of Annual Rental and proration, apportionment and
reconciliation of Additional Rental and other sums due hereunder as of the date
of the termination, no further rent shall be due hereunder.  Upon a partial
taking and the term of this Lease continuing in force as to any part of the
Leased Premises, the Annual Rental or any Additional Rental shall be reduced
proportionately based upon the part or parts of the Leased Premises and/or
other parts of the Building so taken.  If a part of the Building is taken, and
either (i) Landlord's architect or contractor reasonably estimates that
reconstruction would require more than one hundred eighty (180) days; (ii) in
Landlord's good faith, reasonable judgment the remaining portion of the
Building cannot be restored to a functional whole or cannot be restored so as
to be efficient and economically viable to own, operate and maintain as a
commercial office building or (iii) the cost of restoration will require more
than the condemnation proceeds paid to Landlord, then Landlord may elect to
terminate this Lease by delivering written notice of such election to Tenant
not later than sixty (60) days following the Date of the Taking, and this Lease
shall terminate as of a date mutually acceptable to Landlord and Tenant, but in
no event more than one hundred eighty (180) days following such notice, subject
to a proration and apportionment of Annual Rental and proration, apportionment
and reconciliation of Additional Rental and other sums due hereunder.

         Section 12.03    Claims of Landlord and Tenant.  Landlord shall be
entitled to receive the entire award in any proceeding with respect to any
taking (other than for temporary use and occupancy) provided for in this
Article without deduction therefrom for any estate vested in Tenant by this
Lease and Tenant shall receive no part of such award, except as hereinafter
expressly provided.  Tenant shall have the right to make a separate claim with
the condemning authority for (a) any moving expenses incurred by Tenant as a
result of such condemnation; (b) any costs incurred and paid by Tenant in
connection with the layout work, tenant's work or any alteration or improvement
made by and paid for by Tenant to the Leased Premises; (c) the value of any of
Tenant's property taken; and (d) any other separate claim which Tenant may
hereafter be permitted to make, provided, however, that such separate claim
shall not reduce or adversely affect the amount of Landlord's award.  If Tenant
shall not be permitted to make a separate claim in such proceeding, Landlord
may prosecute all claims in such proceeding on behalf of both Landlord and
Tenant in which event Tenant may, if it so elects and at its expense, join with
Landlord in such proceeding, retain co-counsel, attend hearings, present
arguments and generally participate in the conduct of the proceeding; provided,
however, that if Landlord incurs any additional expense because of Tenant's
exercising its rights under this sentence, Tenant will bear such additional
expense.

         Section 12. 04   Distribution of the Award.  The aggregate amount of
all awards received in any proceeding relating to any taking (other than awards
to Tenant pursuant to Section 12.03 or for





                                      -24-
    
<PAGE>   25
   
temporary use or occupancy) is hereinafter called the "Award." Regardless of
the apportionment of the Award in such proceeding, and regardless of any
termination of this Lease, the Award shall be paid to Landlord and distributed
in the following order of priority:

         (a)     If Landlord shall be obligated to repair, alter and/or restore
the remaining part of the Building or base building systems and Building
standard improvements within the Leased Premises pursuant to Section 12.06, the
amount actually expended by Landlord for such repair, alteration and/or
restoration shall be paid to Landlord out of the Award in construction draws,
as such work is performed.

         (b)     Next, if Tenant shall be obligated to repair, alter and/or
restore its above Building standard additions, alterations, installations,
improvements and trade fixtures in the Leased Premises pursuant to Section
12.06, the reasonable amount actually expended by Tenant for such repair,
alteration and/or restoration shall be paid to Tenant out of the Award in
construction draws, as such work is performed and if not performed then
retained by Landlord.

         (c)     Then (whether or not restoration is to be performed under
Section 12.04(a) and 12.04(b)) there shall be paid to Tenant any specifically
awarded sums from the condemning authority for the items enumerated in Section
12.03 less all restoration costs, included in such specific sums awarded to
Tenant, if any.

         (d)     The balance of the Award shall then be paid to Landlord.

         Section 12.05    Temporary Taking of Premises.  If all or any part of
the Leased Premises shall be temporarily taken by condemnation or otherwise for
any public or quasi-public use or purpose (unless Tenant shall have elected to
terminate the term of this Lease in accordance with the option provided in the
last sentence of this Section), this Lease shall nevertheless remain in full
force and effect.  Tenant shall continue to be responsible for all of its
obligations hereunder insofar as such obligations are not affected by such
taking; provided, however, that Tenant shall not be liable for the payment of
Annual Rental, Additional Rental or other sums for the part of the Leased
Premises so temporarily taken.  The Award claims of Landlord and Tenant shall
be handled as provided in Section 12.03. In the event of a temporary taking
which meets the requirement of subsection (a), (b), or (c) of Section 12.02 for
a period in excess of one hundred eighty (180) consecutive days, Tenant may
terminate the term of this Lease upon notice to Landlord given within thirty
(30) days after such taking or, in the case of an indefinite temporary taking
under subsection (a) of Section 12.02, within thirty (30) days after such one

standard improvements within the Leased Premises substantially to their former
condition to the extent feasible to constitute a complete and tenantable
Building and Leased Premises (assuming Tenant performs its restoration pursuant
to Section 12.06(b)). Upon the expiration of any temporary taking which did not
result in a termination of this Lease, Landlord shall restore the base building
systems and Building standard improvements within the Leased Premises to their
former condition as aforesaid.

         (b)     In the event of a taking which does not result in the
termination of this Lease and to the extent that any Award or Awards to Tenant
shall be sufficient for the purpose, Tenant shall restore Tenant's alterations,
improvements, installations, additions and trade fixtures in the remaining
portion of the Leased Premises.

         (c)     During any period of restoration of the Building and the base
building systems and Building standard improvements within the Leased Premises

prorata to the extent that, and for so long as, any portion of the Leased
Premises is not reasonably useable, and is not actually used, by Tenant in the
ordinary conduct of its business.


                    ARTICLE THIRTEEN - REMEDIES AND DEFAULTS

         Section 13.01    Default by Tenant.

         (a)     Any of the following shall be an "Event of Default" by Tenant
under this Lease:

                 (i)      Tenant fails or refuses to pay any installment of
Annual Rental or Additional Rental and such failure or refusal continues for
more than ten (10) days following delivery of written notice to Tenant;
provided, however, following the second (2nd)  notice of nonpayment of Annual
Rental and/or Additional Rental given by Landlord in any lease year, Landlord
shall not be required to give any written notice for any subsequent failure of
Tenant to timely pay any installment of Annual Rental or Additional Rental
occurring during such calendar year; or

                 (ii)     Tenant fails or refuses to perform any of its other
covenants under this Lease, and such failure or refusal continues beyond a
reasonable time to cure such nonperformance, not to exceed thirty (30) days
after written notice from Landlord unless additional time, up to a maximum of
one hundred eighty (180) days in the aggregate is required to cure the default
which despite diligent and continuous effort, cannot by its very nature be
cured within thirty (30) days, provided cure is commenced as soon as
commercially reasonable and is diligently prosecuted to completion.

         (b)     Following an Event of Default and which is not cured within
the cure periods set out above, Landlord shall have the following remedies in
addition to those other remedies at law or in equity which are not inconsistent
therewith:





                                      -26-
    
<PAGE>   27
   
                 (i)      Landlord may terminate this Lease and forthwith
repossess the Leased Premises and be entitled to recover forthwith as damages a
sum of money equal to the total of (a) the cost of recovering the Leased
Premises, (b) the unpaid rent earned through the date of termination, plus
interest thereon at the Default Rate from the due date, and (c) any other sum
of money and damages owed by Tenant to Landlord under this Lease at the time of
termination.

                 (ii)     Landlord may terminate Tenant's right of possession
(but not the Lease) and may repossess the leased premises by self-help,
forcible entry or detainer suit or otherwise, without demand or notice of any
kind to Tenant and without terminating this Lease, in which event Landlord may,
but shall be under no obligation to do so, relet the same for the account of
Tenant, such right to relet being on the following terms and conditions: (a)
Landlord shall only relet on commercially reasonable terms and rent, and if the
Leased Premises are relet in whole or in part, Tenant shall be entitled to a
credit in the net amount of the Annual Rent or Additional Rental received by
Landlord as a result (after deducting all reasonable costs incurred by Landlord
in finding a new tenant, including brokerage fees, agent's commissions,
redecorating costs, construction allowance, lease concessions, parking,
attorneys' fees and any other reasonable costs and expenses incident thereto).
Tenant shall remain obligated to pay the amount of any deficiency in the Annual
Rental or any Additional Rental obtained on such reletting, but if the Annual
Rental or any Additional Rental obtained on such reletting is greater than that
provided for herein plus Landlord's costs, such excess rentals shall be the
sole property of Landlord, and (b) Landlord shall have the right to collect
from Tenant amounts equal to said deficiencies provided for above by suits or
proceedings brought from time to time on one or more occasions without Landlord
being obligated to wait until the expiration of the term of this Lease.  Any
rentals not paid by Tenant when due shall bear interest at the Default Rate.
No such reletting  or other action of Landlord shall be construed as an
election on the part of Landlord to terminate this Lease unless a written
notice of such intention is given to Tenant by Landlord.

         (c)     An election by Landlord of its remedies to terminate Tenant's
right of possession under Section 13.01(b)(ii) shall not prohibit Landlord from
subsequently exercising its rights to terminate the Lease under Section
13.01(b)(i).

         Section 13.02    Default by Landlord.  Landlord shall be in default
hereunder in the event Landlord has not begun and pursued with reasonable
diligence the cure of any failure of Landlord to meet its obligations hereunder
within thirty (30) days of the receipt by Landlord of written notice from
Tenant of the alleged failure to perform. Except as specifically and expressly
provided in this Lease, Tenant shall not have the right to terminate or rescind
this Lease as a result of Landlord's default as to any covenant or agreement
contained in this Lease.  Tenant hereby waives such remedies of termination and
rescission and hereby agrees that Tenant's remedies for default hereunder and
for breach of any promise or inducement shall be limited to a suit for damages
and/or injunction.  In addition, Tenant hereby covenants that, prior to the
exercise of any such remedies, it will give the Mortgagees holding mortgages on
the Building notice and a reasonable time to cure any default by Landlord.

of this Lease a petition in bankruptcy or insolvency or for reorganization or
for the appointment of a receiver or trustee of all or substantially all of
Tenant's assets is filed against Tenant in any court pursuant to any statute
either of the United States or of any state and Tenant fails to secure a
discharge thereof within ninety (90) days, or if Tenant voluntarily files a
petition in bankruptcy or makes an assignment for the benefit of creditors or
petitions for or enters into an arrangement with creditors, the term of this
Lease, at the option of Landlord, exercised within thirty (30) days after
notice of the happening of any one or more of such events, shall terminate on
such date as Landlord shall specify by notice to Tenant, with the same effect
as if the date of termination were the Expiration Date of this Lease, but
Tenant shall remain liable for rent and/or damages attorneys' fees as provided
in Article Thirteen and other damages as may be provided to landlords under the
United States Bankruptcy Code (or any successor thereto).  However, if a
petition for reorganization or for an arrangement is filed by or against
Tenant, Landlord may not terminate the term of this Lease so long as Tenant is
not in default hereunder and, provided this Lease is assumed or affirmed in
such reorganization or arrangement proceeding within the time periods provided
by law.


                     ARTICLE FIFTEEN - COMPLIANCE WITH LAWS

         Section 15.01    Tenant's Compliance with Laws.  Tenant, at its

the Leased Premises, Building, Common Building Facilities, Additional Parking
Area and/or The Texaco Building Complex, (ii) additions, installations,
alterations and improvements made by Tenant, trade fixtures and/or personal
property of Tenant or (iii) a breach by Tenant of its obligations under this
Lease.  Tenant shall not at any time use or occupy the Leased Premises so as to
violate the Certificate of Occupancy for the Building or Common Building
Facilities.  Nothing contained in this Section 15.01, however, shall be deemed
to impose any obligation upon Tenant to make any structural changes or repairs
unless necessitated by reason of a particular use by Tenant of the Leased
Premises.  Tenant shall be responsible for compliance with all current and
future requirements for handicap accessibility within the Leased Premises.

attempted assignment or subletting by Tenant of this Lease of all or any part
of the Leased Premises shall be null and void.

         (b)     Except for an assignment to an "Affiliate" pursuant to Section
16.01 (c) below, if Tenant desires to assign this Lease or sublease all or any
part of the Leased Premises, Tenant shall notify Landlord in writing at least
thirty (30) days prior to the effective date of any proposed assignment or
sublease, describing the terms of the proposed assignment or sublease and the
identity of the proposed assignee or sublessee and available financial
information concerning the business and history of the proposed assignee or
sublessee (and any additional information which Landlord may reasonably
request).  Landlord shall have fifteen (15) days from receipt of all of the
foregoing to elect to (i) reject such proposed assignment or sublease; or (ii)
consent to the proposed assignment or sublease; provided, however, Landlord
will not unreasonably withhold its consent to a proposed assignment or
sublease.

         (c)     Tenant (and any permitted subtenant or assignee) shall have
the right, without the consent of Landlord, to assign this Lease or sublet the

portion of the Leased Premises by, any Affiliate (as hereinafter defined), any
entity that acquires substantially all of the assets of Tenant, any entity into
which Tenant is merged and any entity resulting from a consolidation of Tenant
with some other entity.  The term "Affiliate" shall mean any corporation or
other entity controlled by, under common control with or which controls Tenant
or in which Tenant, directly or indirectly, has a fifty (50%) percent or
greater voting or ownership interest.  However, such subletting or assignment
shall not relieve Tenant of any of its obligations under this Lease.

         (d)     Any assignee of this Lease must execute a written assumption
agreement assuming all of the obligations of Tenant accruing from and after the
date of assignment.

         (e)     No assignment or sublease shall relieve the Tenant which was
the assignor or sublessor from any of its obligations or liabilities under this
Lease; the original Tenant and any subsequent assignee of Tenant's interest
under this Lease shall always remain liable under this Lease.

         (f)     Anything to the contrary not withstanding any and all sums
collected by Tenant (Assignor or Sublessor) in excess of Annual and Additional
Rentals payable hereunder shall be retained by Tenant.

         (g)     No assignment or subletting will be allowed at a rental rate
that is below the rental rate for tenants for the Building located on floors
above the lobby level at the time of the subletting or assignment.  If Landlord
and Tenant can not agree on the rental rate for the Building, the rate will be
determined by the arbitration provision in Exhibit E. Tenant shall pay all of
the costs associated with the arbitration.

continuing right to transfer, sell and/or assign all of its rights and
obligations under this Lease and in the Building, land and Common Building
Facilities and to assign, in whole or in part, the rent payable by Tenant under
this Lease (subject to the terms of this Lease).  Upon the transfer of the
entire estate and interest of Landlord under this Lease, the transferor shall
have no liability for obligations to Tenant relating to events occurring after
and to claims accruing after the date of such transfer.  "Landlord" shall mean
the then-current owner of Landlord's interest and any transferee of the
Landlord's interest shall not be liable for liabilities and obligations of any
former Landlord.

         Section 16.03    No Personal Liability.  Tenant specifically agrees to
look solely to Landlord's interest in the Building, Common Building Facilities
for the recovery of any judgment from Landlord, its officers, employees or
agents, it being agreed that Landlord shall never be personally liable for any
such judgment.  The provisions contained in the foregoing sentence is not
intended to, and shall not, limit any right that Tenant might otherwise have to
obtain injunctive relief against Landlord or Landlord's successors in interest.

mortgagees, lessees (during the last year of the term of this Lease) or
insurers, and (ii) for cleaning and maintenance and making such repairs or
changes in or to the Leased Premises or in or to the Building or its facilities
as may be provided for or permitted by this Lease or as may be mutually agreed
upon by the parties

authorities, provided, however, that the foregoing shall be done upon prior
notice to Tenant, in a manner so as to cause little interference with Tenant's
business operations and, if required by Tenant, accompanied by a designated
representative of Tenant; (iii) during non- business hours to perform
Janitorial Services; and (iv) in emergencies.  Tenant may designate one or more

         Section 20.01    Non-Waiver By Either Party.  Failure by either party
to complain of any action, nonaction or default of the other party shall not
constitute a waiver of any aggrieved party's rights hereunder.  Waiver by
either party of any right for any default of the other party shall not
constitute a waiver of any right for either a subsequent default of the same
obligation or for any other default, past, present or future.


                          ARTICLE TWENTY-ONE - NOTICES

         Section 21.01    Notices to Landlord or Tenant.  Any notice or

                                   EXHIBIT E

                                  ARBITRATION

         In any circumstance for which arbitration or a determination of fair
market rental value (the "Fair Market Value Rate") is specialty provided for
pursuant to this Lease, such arbitration or determination shall be conducted in
accordance with the following provisions:

         (a)     For purposes of determining the Fair Market Value Rate,
Landlord and Tenant shall first meet to attempt to agree upon the Fair Market
Value Rate in accordance to the Provisions in Exhibit C.  Each party shall be
entitled to have its consultants and experts participate in the meetings and
discussions between the parties.  If Landlord and Tenant have not agreed upon
the Fair Market Value Rate and executed and delivered between them a supplement
to this Lease setting forth the same within the time frame called for in
Exhibit C, then either Landlord or Tenant may notify the other that it desires
to invoke the arbitration procedure set forth below.

         (b)     If (i) the Fair Market Value Rate has not been determined
pursuant to subsection (a) above or (ii) the matter being arbitrated does not
involve a determination of the Fair Market Value Rate, then the party invoking
the procedure set forth in subsections (b) through (c) of this Exhibit E shall
give a notice (the "Arbitration Notice") to the other party meeting the
requirements of the (UNIFORM ARBITRATION ACT) (the "Act"), or any successor
statute, and stating that the party sending the Arbitration Notice desires to
meet within ten (10) days to attempt to agree on a single arbitrator to
determine the dispute in question or the Fair Market Value Rate, as the case
may be (the "Arbitrator").  If Landlord and Tenant have not agreed on the
Arbitrator within fifteen (15) days after giving of the Arbitration Notice,
then either Landlord or Tenant, on behalf of both, may apply to the local
office of the American Arbitration Association or any organization which is the
successor thereof (the "AAA") for appointment of the Arbitrator, or, if the AAA
shall not then exist or shall fail, refuse or be unable to act such that the
Arbitrator is not appointed by the AAA within sixty (60) days after application
therefore, then either party may apply to the presiding judge of the court (as
that term is defined in Article 234 of the Act) (the "Court") for the
appointment of the Arbitrator and the other party shall not raise any question
as to the Court's full power and jurisdiction to entertain the application and
make the appointment.  The date on which the Arbitrator is appointed, by the
agreement of the parties, or otherwise, is referred to herein as the
"Appointment Date".  If any Arbitrator appointed hereunder shall be unwilling
to unable, for any reason, to serve, or continue to serve, a replacement
arbitrator shall be appointed in the same manner as the original Arbitrator.

         (c)     The arbitration shall be conducted in accordance with the then
prevailing rules of the local office of the AAA, modified as follows:

                 (i)      To the extent that the Act or any successor statute
imposes requirements different than those of the AAA in order for the decision
of the Arbitrator to be enforceable in the courts of the State of Oklahoma,
such requirements shall be complied with in the arbitration.

<PAGE>   46
   
                 (ii)     The Arbitrator shall be disinterested and impartial,
have no economic interest in the outcome, shall not be affiliated with the
Landlord or the Tenant and shall be (A) for purposes of determining the Fair
Market Value Rate, an MAI appraiser with at least ten (10) years experience in
the determination of fair market rentals in Comparable Buildings (B) for
purposes of any dispute under Section 4.02(e) or Exhibit D, an independent

other disputes or determinations to be made in accordance with this section, a
qualified and impartial person who shall have had at least ten (10) years
experience in the City of Tulsa, Oklahoma in a calling connected with the
matters of the dispute.

                 (iii)    Before hearing any testimony or receiving any
evidence, the Arbitrator shall be sworn to hear and decide the controversy
faithfully and fairly by an officer authorized to administer an oath and a
written copy thereof shall be delivered to the Landlord and the Tenant.

                 (iv)     Within twenty (20) days after the Appointment Date,
Landlord and Tenant shall deliver to the Arbitrator two (2) copies of (A) a
written statement setting forth in reasonable detail their respective positions
with respect to the dispute in question, which statement may be accompanied by
such evidence as the submitting party shall deem appropriate, or (B) their
respective written determinations of the Fair Market Value Rate, as applicable
(in each case, a "Determination").  After the submission of any Determination,
the submitting party may not make any additions to or deletions from or
otherwise change such Determination.  If either party fails to so deliver its
Determination within such time period, time being of the essence with respect
thereto, such party shall be deemed to have irrevocably waived its right to
deliver a Determination and the Arbitrator without holding a hearing, shall
accept the Determination of the submitting party as the result with respect to
the dispute in question or the Fair Market Value Rate, as applicable.  If each
party submits a Determination within the twenty (20) day period described
above, the Arbitrator shall, promptly after its receipt of the second
Determination, deliver a copy of each party's Determination to the other party.
For purposes of determining the Fair Market Value Rate, if the higher of the
Determinations so submitted by the parties exceeds the lower of such
Determinations by not more than five percent (5%) of the lower Determination,
then the Arbitrator, without holding a hearing, shall determine that the Fair
Market Value Rate is the mathematical average of the two Determinations
thereof.

                 (v)      If (A) the Fair Market Value Rate has not been
determined pursuant to clause (iv) of this subparagraph or (B) the matter being
arbitrated does not involve a determination of the Fair Market Value Rate, then
not less than fifteen (1 5) days nor more than thirty (30) days after the
earlier to occur of (1) the expiration of the twenty (20) day period provided
for in clause (iv) of this subparagraph or (2) the Arbitrator's receipt of both
of the Determinations from the parties (such earlier date is referred to herein
as the ("Submission Date"), and upon not less than ten (10) days notice to the
parties, the Arbitrator shall hold one or more hearings with respect to the
dispute in question or the determination of the Fair Market Value Rate, as
applicable.  The hearings shall be held in the City of Tulsa, Oklahoma at such
location and time as shall be specified by the Arbitrator.  Each of the parties
shall be entitled to present all relevant evidence and to cross-examine
witnesses

all events all hearings, pursuant to this Section, shall be concluded not later
than forty five (45) days after the Submission Date.

                 (vi)     Except as otherwise provided in clause (iv) of this
subparagraph, the Arbitrator shall be instructed, and shall be empowered only,
to select that one of the Determinations which the Arbitrator believes is the
more accurate determination of the dispute in question for the Fair Market
Value Rate, as applicable.  Without limiting the generality of the foregoing,
in rendering his or her decision, the Arbitrator shall not add to, subtract
from or otherwise modify the provisions of this Lease or either of the
Determinations.

                 (vii)    The Arbitrator shall render his or her determination
as to the selection of a Determination in a signed and acknowledged written
instrument, original counterparts of which shall be sent simultaneously to the
Landlord and the Tenant, within ten (10) days after the earlier to occur of (A)
his or her determination of the dispute in question or the Fair Market Value
Rate, as applicable, pursuant to clause (iv) of this subparagraph or (B) the
conclusion of the hearing(s) required by clause (v) of this subparagraph,

                 (viii)   If the rental commencement date for any space to be
leased by Tenant pursuant to this Lease for which the Fair Market Value Rate is
being determined begins prior to the commencement of or completion of the
procedures for determining such rental rate as herein provided, rent shall be
provisionally determined and paid for by Tenant based on Landlord's initial
calculation of the Fair Market Value Rate beginning on the commencement date
provided in the Lease.  Any overpayment by, Tenant resulting from any reduction
in the Fair Market Value Rate upon its final determination pursuant to the
provisions hereof, together with interest thereon from the date or dates of
overpayment at the Prime Interest Rate, until such rent is credited to Tenant,
shall be credited to Tenant's next succeeding Annual Rental payments.

                 (ix)     The Arbitrator shall resolve any Operating Expense
dispute as he may determine and his decision shall be binding on Landlord and
Tenant.  Each party shall present its case to the Arbitrator and each party's
auditors involved in the dispute shall be entitled to present evidence and
attend hearings.

         (d)     This provision shall constitute a written agreement under the
Act to submit those disputes for which arbitration is specifically provided for
pursuant to this Lease, including any dispute regarding the determination of
the Fair Market Value Rate, to arbitration.

         (e)     The arbitration decision, determined as provided in this
Section, shall be conclusive and binding on the parties, shall constitute an
"award" by the Arbitrator within the meaning of the AAA rules and applicable
law and judgment may be entered thereon in any court of competent jurisdiction.

arbitration (including, without being limited to, the fees and expenses of its
counsel and of experts and witnesses retained or called by it).  Each party

such fees and expenses.
