                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the detailed
information and financial statements and the notes thereto appearing elsewhere
in this Prospectus. The pro forma information gives effect to the reorganization
of the Company, the 1995 Acquisition and the 1996 Acquisition. See "The
Company." Unless otherwise indicated, the information in this Prospectus assumes
no exercise of the Underwriters' over-allotment option. Certain terms relating
to the oil and gas industry are defined in "Glossary of Oil and Gas Terms." As
noted in the glossary, PV-10 is calculated without giving effect to income
taxes.
 
                                  THE COMPANY
 
   
     Titan is an independent energy company engaged in the exploration,
development and acquisition of oil and gas properties. Since its inception in
March 1995, the Company has experienced significant growth in reserves,
production and cash flow by acquiring and exploiting producing properties
primarily in the Permian Basin of west Texas and southeastern New Mexico.
    
 
   
     In December 1995, the Company acquired a concentrated group of Permian
Basin producing oil and gas properties from a large independent company for
approximately $40.6 million (the "1995 Acquisition"). On October 31, 1996, the
Company acquired additional Permian Basin producing properties from a major
integrated company for approximately $135.5 million (the "1996 Acquisition"). As
of September 30, 1996, the Company had pro forma estimated net proved reserves
of approximately 17.8 MMBbls of oil and 280.8 Bcf of natural gas, or an
aggregate of 64.6 MMBOE with a PV-10 of $292.1 million. If, in calculating the
PV-10, the Company's oil and gas prices at October 31, 1996 were substituted for
the prices at September 30, 1996, the PV-10 would be $351.9 million. The prices
of the Company's oil decreased 4% and gas increased 33%, respectively, from
September 30, 1996 to October 31, 1996. Approximately 62% of these reserves were
classified as proved developed. The Company acquired, explored for and developed
its reserves for an average reserve replacement cost of approximately $2.73 per
BOE through September 30, 1996, assuming the 1996 Acquisition was consummated on
September 30, 1996. Pro forma production for the nine months ended September 30,
1996 was 12,227 BOE per day, resulting in an annualized pro forma proved
reserves to production ratio of 14.5 to one.
    
 
   
     The Company prefers to acquire properties over which it can exercise
operating control. The Company operated 456 gross wells (389 net wells) on a pro
forma basis at September 30, 1996, and these operated properties represented
approximately 71% of its pro forma proved developed producing PV-10 and 83% of
the Company's pro forma proved PV-10 at September 30, 1996. The Company's
emphasis on controlling the operation of its properties enables the Company to
manage expenses, capital allocation and other aspects of development and
exploration.
    
 
   
     The Company's oil and gas properties are located in 57 fields in the
Permian Basin, one of the most prolific oil and gas producing regions in North
America. Approximately 70% of the Company's PV-10 of total proved reserves is
concentrated in 12 principal fields located in this region. The region is
characterized by complex geology with numerous known producing horizons and
provides significant opportunities to increase reserves, production and ultimate
recoveries through development, exploratory and horizontal drilling,
recompletions, secondary and tertiary recovery methods, and use of 3-D seismic
and other advanced technologies.
    
 
   
     The Company believes that its personnel provide it with competitive
advantages for exploiting these opportunities in the Permian Basin and other
complex producing basins in North America. Members of the Company's management
team have an average of 25 years experience in the oil and gas industry and have
operating experience in all aspects of the industry, in particular deep well and
horizontal drilling. They have formulated and supervised acquisitions,
exploration projects, development drilling programs and production enhancement
plans, including workovers and enhanced recovery projects. In addition,
management has a significant equity investment in the Company. Giving effect to
this offering and assuming the exercise by management of all of their options to
acquire Common Stock, management will beneficially own an aggregate of 20% of
the Company's outstanding Common Stock.

                               BUSINESS STRATEGY
 
   
     The Company's strategy is to grow reserves, production and net income per
share through (i) the acquisition of producing properties that provide
significant development and exploratory drilling potential, (ii) the
exploitation and development of its reserve base, (iii) the exploration for oil
and gas reserves and (iv) the implementation of a low operating and overhead
cost structure.
    
 
    
     - Acquisitions. The Company seeks to acquire oil and gas properties that
       provide opportunities for the addition of reserves, production and value
       through low risk exploitation and development, high-potential
       exploration and control of operations. The Company believes that these
       criteria can be met in the Permian Basin and in other North American
       basins that have had high historical cumulative production levels that
       represent a relatively small percentage of the recoverable in-place
       reserves. At September 30, 1996, the Company had acquired and developed
       64.6 MMBOE of proved oil and gas reserves at an average reserve
       replacement cost of $2.73 per BOE, assuming the 1996 Acquisition was
       consummated on September 30, 1996, which compares to an average reserve
       replacement cost of $4.85 per BOE (for 1993 through 1995) for the 184
       independent oil and gas companies included in the Arthur Andersen 1996
       Oil and Gas Reserve Disclosures.
    
 
   
     - Exploitation of Reserve Base. The Company engages in horizontal and
       infill drilling activities, major workovers, recompletions, secondary
       and tertiary recovery operations, and other production enhancement
       techniques in order to increase reserves and production. On a pro forma
       basis, the Company has identified 53 drilling locations on
       Company-operated properties, which include 14 proved locations and 39
       unproven locations. In drilling a portion of these wells in 1997, the
       Company expects to spend approximately $12.9 million to develop proved
       locations and $6.8 million to develop unproven locations. The Company
       has also identified an additional 90 unproven drilling locations on
       Company-owned, but nonoperated, properties.
    
 
     - Exploration Activities. The Company seeks to apply management's
       extensive geological and drilling expertise and 3-D seismic technology
       to identify and develop exploration projects. As part of its exploration
       strategy, the Company attempts to reduce the costs and risks of its
       exploration activities by, in selected circumstances, applying 3-D
       seismic technology, drilling wells with multiple pay objectives in known
       producing areas and selling interests in its exploration prospects to
       industry partners. A large portion of the Company's efforts have focused
       on deep well opportunities in historically prolific fields.
 
   
     - Low Cost Structure. The Company has implemented and plans to maintain
       a low overhead and operating cost structure to enhance the profitability
       and the exploitation potential of its properties. The Company provides
       incentive stock awards to its senior management team in lieu of
       comparatively higher salary levels in order to align management's
       interests with stockholders, maintain relatively low general and
       administrative expense and increase the amount of cash flow available
       for reinvestment by the Company. The Company also seeks to be an
       efficient operator and achieve reductions in labor and other field-level
       costs from those incurred by previous operators of its properties. By
       operating a significant portion of its daily production, the Company
       believes it is well positioned to control the expenses and timing of
       development and exploitation of such properties and to better manage
       such cost reduction efforts.

(2) EBITDAX is presented because of its wide acceptance as a financial indicator
    of a company's ability to service or incur debt. EBITDAX (as used herein) is
    calculated by adding interest, income taxes, depletion, depreciation and
    amortization, amortization of stock option awards, and exploration and
    abandonment costs to net income (loss). Interest includes interest expense
    accrued and amortization of deferred financing costs. EBITDAX should not be
    considered as an alternative to earnings (loss) or operating earnings
    (loss), as defined by generally accepted accounting principles, as an
    indicator of the Company's financial performance, as an alternative to cash
    flow as a measure of liquidity or as being comparable to other similarly
    titled measures of other companies.

Factors." Should one or more of these risks or uncertainties occur, or should
underlying assumptions prove incorrect, actual results may vary materially and
adversely from those anticipated, believed, estimated or otherwise indicated.
Investors should carefully consider the following risk factors, in addition to
other information contained in this Prospectus, before purchasing the shares of
Common Stock offered hereby.
 
VOLATILITY OF OIL AND GAS PRICES
 
     The Company's revenues, operating results and future rate of growth are
highly dependent upon the prices received for the Company's oil and gas.
Historically, the markets for oil and gas have been volatile and may continue to
be volatile in the future. Revenues generated from the oil and gas operations of
the Company will be highly dependent on the future prices of oil and gas.
Various factors beyond the control of the Company will affect prices of oil and
gas, including the worldwide and domestic supplies of oil and gas, the ability
of the members of the Organization of Petroleum Exporting Countries ("OPEC") to
agree to and maintain oil price and production controls, political instability
or armed conflict in oil-producing regions, the price and level of foreign
imports, the level of consumer demand, the price and availability of alternative
fuels, the availability of pipeline capacity, weather conditions, domestic and
foreign governmental regulations and taxes and the overall economic environment.
 
   
     Recent political instability in the Middle East has had a significant
effect on world oil markets. In the third quarter of 1996, prices of oil
experienced substantial price fluctuations, including large price escalations,
resulting in part from Iraq's attack against the Kurdish rebels in Northern Iraq
and the subsequent United States response. On September 30, 1996, the posted
price for West Texas Intermediate Crude was $22.75 per Bbl, as posted by the
Company's major purchaser. The Company is unable to predict the long-term
effects of these and other conditions on the prices of oil. Moreover, it is
possible that prices for any oil the Company produces will be lower than current
prices received by the Company.
    
 
   
     Historically, the market for natural gas has been volatile and is likely to
continue to be volatile in the future. Prices for natural gas are subject to
wide fluctuation in response to market uncertainty, changes in supply and demand
and a variety of additional factors (including those referred to in the first
paragraph of this Risk Factor), all of which are beyond the Company's control.
    
 
     Any significant decline in the price of oil or gas would adversely affect
the Company's revenues and operating income and may require a reduction in the
carrying value of the Company's oil and gas properties. See "Risk
Factors -- Uncertainty of Reserve Information and Future Net Revenue Estimates,"
"Business and Properties -- Competition" and "Business and
Properties -- Governmental Regulation."
 
UNCERTAINTY OF RESERVE INFORMATION AND FUTURE NET REVENUE ESTIMATES
 
   
     There are numerous uncertainties inherent in estimating quantities of
proved reserves and their values, including many factors beyond the Company's
control. The reserve information set forth in this Prospectus represents
estimates only. Although the Company believes such estimates to be reasonable,
reserve estimates are imprecise and should be expected to change as additional
information becomes available.
    
 
   
     Estimates of oil and gas reserves, by necessity, are projections based on
engineering data, and there are uncertainties inherent in the interpretation of
such data as well as the projection of future rates of production and the timing
of development expenditures. Reserve engineering is a subjective process of
estimating underground accumulations of oil and gas that are difficult to
measure. The accuracy of any reserve estimate is a function of the quality of
available data, engineering and geological interpretation and judgment.
Estimates
    
 
                                        8
<PAGE>   11
 
   
of economically recoverable oil and gas reserves and of future net cash flows
necessarily depend upon a number of variable factors and assumptions, such as
historical production from the area compared with production from other
producing areas, the assumed effects of regulations by governmental agencies and
assumptions concerning future oil and gas prices, future operating costs,
severance and excise taxes, development costs and workover and remedial costs,
all of which may in fact vary considerably from actual results. For these
reasons, estimates of the economically recoverable quantities of oil and gas
attributable to any particular group of properties, classifications of such
reserves based on risk of recovery and estimates of the future net cash flows
expected therefrom may vary substantially. Moreover, there can be no assurance
that the Company's reserves will ultimately be produced or that the Company's
proved undeveloped reserves will be developed within the periods anticipated.
Any significant variance in the assumptions could materially affect the
estimated quantity and value of the Company's reserves. Actual production,
revenues and expenditures with respect to the Company's reserves will likely
vary from estimates, and such variances may be material. See "Business and
Properties -- Oil and Natural Gas Reserves."
    
 
RISK OF HEDGING ACTIVITIES
 
     The Company's use of energy swap arrangements to reduce its sensitivity to
oil and gas price volatility is subject to a number of risks. If the Company's
reserves are not produced at the rates estimated by the Company due to
inaccuracies in the reserve estimation process, operational difficulties or
regulatory limitations, the Company would be required to satisfy its obligations
under fixed price sales and hedging contracts on potentially unfavorable terms
without the ability to hedge that risk through sales of comparable quantities of
its own production. Further, the terms under which the Company enters into fixed
price sales and hedging contracts are based on assumptions and estimates of
numerous factors such as cost of production and pipeline and other
transportation costs to delivery points. Substantial variations between the
assumptions and estimates used by the Company and actual results experienced
could materially adversely affect the Company's anticipated profit margins and
its ability to manage the risk associated with fluctuations in oil and gas
prices. Additionally, the fixed price sales and hedging contracts limit the
benefits the Company will realize if actual prices rise above the contract
prices.
 
     In addition, fixed price sales and hedging contracts are subject to the
risk that the other party may prove unable or unwilling to perform its
obligations under such contracts. Any significant nonperformance could have a
material adverse financial effect on the Company.
 
   
     As of September 30, 1996, excluding the effects of the 1996 Acquisition,
the Company had approximately 58% of its oil production and approximately 73% of
its natural gas production (based on the first three quarters' production)
committed to hedging contracts through December 1996. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Other Matters."
    
 
LIMITED OPERATING HISTORY; RAPID GROWTH
 
   
     The Company, which began operations in March 1995, has a brief operating
history upon which investors may base their evaluation of the Company's
performance. As a result of its brief operating history and rapid growth, the
operating results from the Company's historical periods are not readily
comparable and may not be indicative of future results. There can be no
assurance that the Company will continue to experience growth in, or maintain
its current level of, revenues, oil and gas reserves or production. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
    
 
     The Company's rapid growth has placed significant demands on its
administrative, operational and financial resources. Any future growth of the
Company's oil and gas reserves, production and operations would place
significant further demands on the Company's financial, operational and
administrative resources. The Company plans to hire 20 to 25 additional
employees following the 1996 Acquisition. The Company's future performance and
profitability will depend in part on its ability to successfully integrate the
administrative and financial functions of acquired properties into the Company's
operations, to hire additional personnel and to implement necessary enhancements
to its management systems to respond to changes in its business. There can be no
assurance that the Company will be successful in these efforts. The inability of
the Company to
 
                                        9
<PAGE>   12
 
integrate acquired properties, to hire additional personnel or to enhance its
management systems could have a material adverse effect on the Company's results
of operations.
 
SUBSTANTIAL CAPITAL REQUIREMENTS
 
   
     The Company makes, and will continue to make, substantial capital
expenditures for the exploration, development, acquisition and production of its
oil and gas reserves. The Company intends to finance such capital expenditures
primarily with funds provided by operations and borrowings under its $250
million Credit Agreement, which currently has a borrowing base of $165 million.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources." The cost of the 1995 Acquisition
was approximately $40.6 million, and the cost of the 1996 Acquisition was
approximately $135.5 million. The Company's direct capital expenditures for oil
and gas producing activities, excluding property acquisitions, were $2.0 million
for the nine months ended December 31, 1995 and $7.5 million for the nine months
ended September 30, 1996.
    
 
   
     If revenues decrease as a result of lower oil or gas prices or otherwise,
the Company may have limited ability to expend the capital necessary to replace
its reserves or to maintain production at current levels, resulting in a
decrease in production over time. If the Company's cash flow from operations and
availability under the Credit Agreement are not sufficient to satisfy its
capital expenditure requirements, there can be no assurance that additional debt
or equity financing will be available to meet these requirements. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
    
 
RESERVE REPLACEMENT RISK
 
     The Company's future success depends upon its ability to find, develop or
acquire additional oil and gas reserves that are economically recoverable. The
proved reserves of the Company will generally decline as reserves are depleted,
except to the extent that the Company conducts successful exploration or
development activities or acquires properties containing proved reserves, or
both. In order to increase reserves and production, the Company must continue
its development and exploration drilling and recompletion programs or undertake
other replacement activities. The Company's current strategy includes increasing
its reserve base through acquisitions of producing properties, continued
exploitation of its existing properties and exploration of new and existing
properties. There can be no assurance, however, that the Company's planned
development and exploration projects and acquisition activities will result in
significant additional reserves or that the Company will have continuing success
drilling productive wells at low finding and development costs. Furthermore,
while the Company's revenues may increase if prevailing oil and gas prices
increase significantly, the Company's finding costs for additional reserves
could also increase. For a discussion of the Company's reserves, see "Business
and Properties -- Oil and Natural Gas Reserves."
 
DRILLING AND OPERATING RISKS
 
     Drilling activities are subject to many risks, including the risk that no
commercially productive reservoirs will be encountered. There can be no
assurance that new wells drilled by the Company will be productive or that the
Company will recover all or any portion of its investment. Drilling for oil and
gas may involve unprofitable efforts, not only from dry wells, but from wells
that are productive but do not produce sufficient net revenues to return a
profit after drilling, operating and other costs. The cost of drilling,
completing and operating wells is often uncertain. The Company's drilling
operations may be curtailed, delayed or canceled as a result of numerous
factors, many of which are beyond the Company's control, including economic
conditions, mechanical problems, title problems, weather conditions, compliance
with governmental requirements and shortages or delays in the delivery of
equipment and services. The Company's future drilling activities may not be
successful and, if unsuccessful, such failure may have a material adverse effect
on the Company's future results of operations and financial condition.
 
                                       10
<PAGE>   13
 
     In addition, the Company's use of 3-D seismic requires greater pre-drilling
expenditures than traditional drilling strategies. There can be no assurance
that the Company's drilling program will be successful or that unsuccessful
drilling efforts will not have a material adverse effect on the Company.
 
   
     The Company's operations are subject to hazards and risks inherent in
drilling for and producing and transporting oil and gas, such as fires, natural
disasters, explosions, encountering formations with abnormal pressures,
blowouts, cratering, pipeline ruptures and spills, any of which can result in
the loss of hydrocarbons, environmental pollution, personal injury claims and
other damage to properties of the Company and others.
    
 
     The Company expects to drill a number of deep vertical and horizontal wells
in the future. The Company's deep and/or horizontal drilling activities involve
greater risk of mechanical problems than other drilling operations. Future
drilling activity may be significantly more expensive than such activity to
date.
 
   
     As protection against operating hazards, the Company maintains insurance
coverage against some, but not all, potential losses. The Company may elect to
self-insure in circumstances in which management believes that the cost of
insurance, although available, is excessive relative to the risks presented. The
occurrence of an event that is not covered, or not fully covered, by insurance
could have a material adverse effect on the Company's financial condition and
results of operations.
    
 
ACQUISITION RISKS
 
   
     The Company's rapid growth since its inception in March 1995 has been
largely the result of acquisitions of producing properties. The Company expects
to continue to evaluate and pursue acquisition opportunities available on terms
management considers favorable to the Company. The successful acquisition of
producing properties requires an assessment of recoverable reserves, future oil
and gas prices, operating costs, potential environmental and other liabilities
and other factors beyond the Company's control. This assessment is necessarily
inexact and its accuracy is inherently uncertain. In connection with such an
assessment, the Company performs a review of the subject properties it believes
to be generally consistent with industry practices. This review, however, will
not reveal all existing or potential problems, nor will it permit a buyer to
become sufficiently familiar with the properties to assess fully their
deficiencies and capabilities. Inspections may not be performed on every well,
and structural and environmental problems are not necessarily observable even
when an inspection is undertaken. The Company generally assumes preclosing
liabilities, including environmental liabilities, and generally acquires
interests in the properties on an "as is" basis. With respect to its
acquisitions to date, the Company has no material commitments for capital
expenditures to comply with existing environmental requirements. There can be no
assurance that the Company's acquisitions will be successful. Any unsuccessful
acquisition could have a material adverse effect on the Company.
    
 
COMPLIANCE WITH GOVERNMENT REGULATIONS
 
     The Company's business is subject to federal, state and local laws and
regulations relating to the exploration for, and the development, production and
transportation of, oil and gas, as well as safety matters. Although the Company
believes it is in substantial compliance with all applicable laws and
regulations, the requirements imposed by such laws and regulations are
frequently changed and subject to interpretation, and the Company is unable to
predict the ultimate cost of compliance with these requirements or their effect
on its operations. Significant expenditures may be required to comply with
governmental laws and regulations and may have a material adverse effect on the
Company's financial condition and results of operations. See "Business and
Properties -- Governmental Regulation."
 
COMPLIANCE WITH ENVIRONMENTAL REGULATIONS
 
   
     The Company's operations are subject to complex and constantly changing
environmental laws and regulations adopted by federal, state and local
governmental authorities. The implementation of new, or the modification of
existing, laws or regulations could have a material adverse effect on the
Company. The discharge of oil, gas or other pollutants into the air, soil or
water may give rise to significant liabilities on the part of the Company to the
government and third parties and may require the Company to incur substantial
costs of remediation. Moreover, the Company has agreed to indemnify sellers of
producing properties
    
 
                                       11
<PAGE>   14
 
   
purchased by the Company in the 1995 Acquisition and the 1996 Acquisition
against environmental claims associated with such properties. No assurance can
be given that existing environmental laws or regulations, as currently
interpreted or reinterpreted in the future, or future laws or regulations will
not materially adversely affect the Company's results of operations and
financial condition or that material indemnity claims will not arise against the
Company with respect to properties acquired by the Company. See "Business and
Properties -- Environmental Matters."
    
 
MARKETABILITY OF PRODUCTION
 
     The marketability of the Company's production depends in part upon the
availability, proximity and capacity of natural gas gathering systems, pipelines
and processing facilities. Most of the Company's natural gas is delivered
through gas gathering systems and gas pipelines that are not owned by the
Company. Federal and state regulation of oil and gas production and
transportation, tax and energy policies, changes in supply and demand and
general economic conditions all could adversely affect the Company's ability to
produce and market its oil and gas. Any dramatic change in market factors could
have a material adverse effect on the Company.
 
     The PV-10 referred to in this Prospectus should not be construed as the
current market value of the estimated oil and gas reserves attributable to the
Company's properties. In accordance with applicable requirements, the estimated
discounted future net cash flows from proved reserves are generally based on
prices and costs as of the date of the estimate, whereas actual future prices
and costs may be materially higher or lower. Actual future net cash flows also
will be affected by factors such as the amount and timing of actual production,
supply and demand for oil and gas, curtailments or increases in consumption by
gas purchasers and changes in governmental regulations or taxation. The timing
of actual future net cash flows from proved reserves, and thus their actual
present value, will be affected by the timing of both the production and the
incurrence of expenses in connection with development and production of oil and
gas properties. In addition, the 10% discount factor, which is required to be
used to calculate discounted future net cash flows for reporting purposes, is
not necessarily the most appropriate discount factor based on interest rates in
effect from time to time and risks associated with the Company or the oil and
gas industry in general.
 
DEPENDANCE ON KEY PERSONNEL
 
     The Company's success has been and will continue to be highly dependent on
Jack Hightower, its Chairman of the Board and Chief Executive Officer, and a
limited number of other senior management personnel. Loss of the services of Mr.
Hightower or any of those other individuals could have a material adverse effect
on the Company's operations. In addition, as a result of the 1996 Acquisition,
the Company plans to employ 20 to 25 new employees and will face competition for
such personnel from other companies. There can be no assurance that the Company
will be successful in hiring or retaining key personnel. The Company's failure
to hire additional personnel or retain its key personnel could have a material
adverse effect on the Company.
 
CONTROL BY EXISTING STOCKHOLDERS
 
   
     Upon completion of this offering, directors, executive officers and
principal stockholders of the Company, and certain of their affiliates, will
beneficially own approximately 59% of the Company's outstanding Common Stock
(approximately 56% if the Underwriters exercise their over-allotment option in
full). Accordingly, these stockholders, as a group, will be able to control the
outcome of stockholder votes, including votes concerning the election of
directors, the adoption or amendment of provisions in the Company's Certificate
of Incorporation or Bylaws and the approval of mergers and other significant
corporate transactions. The existence of these levels of ownership concentrated
in a few persons makes it unlikely that any other holder of Common Stock will be
able to affect the management or direction of the Company. These factors may
also have the effect of delaying or preventing a change in the management or
voting control of the Company, including transactions that otherwise could
involve payment of a premium over prevailing market prices to holders of Common
Stock. See "Principal and Selling Stockholders."
    
 
                                       12
<PAGE>   15
 
COMPETITION
 
   
     The Company operates in the highly competitive areas of oil and gas
exploration, development, acquisition and production with other companies, many
of which have substantially larger financial resources, staffs and facilities.
In seeking to acquire desirable producing properties or new leases for future
exploration and in marketing its oil and gas production, the Company faces
intense competition from both major and independent oil and gas companies. Many
of these competitors have financial and other resources substantially in excess
of those available to the Company. See "Business and Properties -- Competition."
This highly competitive environment could have a material adverse effect on the
Company.
    
 
CUMULATIVE VOTING; BLANK CHECK PREFERRED STOCK
 
   
     The Company's Certificate of Incorporation (i) provides for cumulative
voting for the election of directors and (ii) authorizes the Board of Directors
of the Company to issue up to 10,000,000 shares of preferred stock without
stockholder approval and to set the rights, preferences and other designations,
including voting rights, of those shares as the Board of Directors may
determine. These provisions, alone or in combination with each other and with
the matters described in "Risk Factors -- Control by Existing Stockholders," may
discourage transactions involving actual or potential changes of control of the
Company, including transactions that otherwise could involve payment of a
premium over prevailing market prices to holders of Common Stock. The Company
also is subject to provisions of the Delaware General Corporation Law that may
make some business combinations more difficult. See "Description of Capital
Stock -- Delaware Law Provisions."
    
 
ABSENCE OF DIVIDENDS ON COMMON STOCK
 
     The Company does not currently intend to pay regular cash dividends on the
Common Stock. In addition, the Credit Agreement prohibits the payment of cash
dividends. See "Dividend Policy."
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
     Sales of a substantial number of shares of Common Stock in the public
market following this offering could adversely affect the market price for the
Common Stock. The Company believes all of the shares of Common Stock currently
outstanding will be eligible for sale under Rule 144 on October 1, 1998, based
on current Securities and Exchange Commission (the "Commission") rules and
subject to compliance with the manner-of-sale, volume and other limitations of
Rule 144. The Commission has proposed an amendment to Rule 144 that, if adopted,
could permit those shares to be sold earlier. Some investors have the right to
require the Company to register the public resale of their shares before that
time. See "Shares Eligible for Future Sale" and "Description of Capital
Stock -- Registration Rights."
 
IMMEDIATE AND SUBSTANTIAL DILUTION
 
     Purchasers of the Common Stock in the offering will experience an immediate
and substantial dilution in pro forma net tangible book value per share. These
investors will also experience additional dilution upon the exercise of
outstanding options. See "Dilution."
 
NO PRIOR PUBLIC MARKET; POSSIBLE STOCK PRICE VOLATILITY
 
   
     Before this offering, there has been no public market for the Common Stock,
and an active public market for the Common Stock may not develop or be
sustained. The initial public offering price will be determined through
negotiations between the Company and the Representatives of the Underwriters
based on several factors that may not be indicative of future market prices. See
"Underwriting" for a discussion of the factors to be considered in determining
the initial public offering price. The trading price of the Common Stock and the
price at which the Company may sell securities in the future could be subject to
large fluctuations in response to changes in government regulations, quarterly
variations in operating results, litigation, general market conditions, the
prices of oil and gas, the liquidity of the Company and the Company's ability to
raise additional funds and other events.

                                  THE COMPANY
 
   
     Titan Exploration, Inc. is an independent energy company engaged in the
exploration, development and acquisition of oil and gas properties. The Company
was formed in 1996 for the purpose of becoming the holding company for Titan
Resources, L.P. (the "Partnership") pursuant to the terms of an Exchange
Agreement and Plan of Reorganization dated September 30, 1996 (the "Exchange
Agreement"). The Partnership was formed in March 1995 and has grown primarily
through acquisitions of oil and gas properties and the exploitation of these
properties. See "Business and Properties -- Principal Oil and Gas Properties."
Under the Exchange Agreement, effective September 30, 1996, (i) the limited
partners of the Partnership transferred all of their limited partnership
interests to the Company in exchange for an aggregate of 19,318,199 shares of
Common Stock, and (ii) the shareholders of Titan Resources I, Inc., a Texas
corporation that is the general partner of the Partnership, transferred all of
the issued and outstanding stock of that corporation to the Company in exchange
for an aggregate of 231,814 shares of Common Stock. These transactions are
referred to in this Prospectus as the "Conversion." As a result of the
Conversion, Titan Exploration, Inc. owns, directly or indirectly, all the
partnership interests in the Partnership and conducts its active business
operations through the Partnership. References to the "Company" or to "Titan"
are to Titan Exploration, Inc. and its predecessors and subsidiaries, including
the Partnership.
    
 
     Titan's principal executive offices are located at 500 West Texas, Suite
500, Midland, Texas 79701 and its telephone number is (915) 682-6612.
 
                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the 12,500,000 shares of
Common Stock offered by the Company are estimated to be approximately $122.2
million ($140.8 million if the Underwriters exercise their over-allotment option
in full), based on the initial public offering price of $10.50 per share and
after deducting the estimated underwriting discounts and commissions and
estimated offering expenses.
    
 
   
     The Company intends to use the net proceeds for exploration, development
and acquisition activities and other general corporate purposes. Pending use of
the net proceeds in this manner, the Company intends to use the net proceeds to
repay indebtedness under the Company's Amended and Restated Credit Agreement,
dated October 31, 1996 (the "Credit Agreement"), incurred in connection with the
1996 Acquisition. At September 30, 1996, on a pro forma basis, the outstanding
principal balance of indebtedness under the Credit Agreement would have been
$145.1 million, a substantial amount of which was incurred in connection with
the 1996 Acquisition. For the nine months ended September 30, 1996, the Credit
Agreement had an average interest rate of 6.75% per annum, and the indebtedness
has a final maturity of January 1, 2001. As a result of an interest rate swap
agreement, the Company effectively has a fixed interest rate of 6.72% on $10
million of the revolving portion of the Credit Agreement. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources" for a description of the Credit
Agreement. Affiliates of J.P. Morgan Securities Inc. (one of the Underwriters)
and First Union Corporation (an owner of in excess of 5% of the Common Stock)
are participants in that indebtedness and will each be entitled to receive 20%
of any repayments of that indebtedness. See "Certain Transactions" and
"Underwriting."
    
 
                                DIVIDEND POLICY
 
     The Company has never declared or paid cash dividends on its Common Stock
and anticipates that all future earnings will be retained for development of its
business. In addition, the Credit Agreement prohibits the payment of cash
dividends on Common Stock. The Board of Directors of the Company may review the
Company's dividend policy from time to time in light of, among other things, the
Company's earning and financial position and limitations imposed by the
Company's debt instruments. See "Management's Discussion and Analysis of
Financial Condition and Results of Operation -- Liquidity and Capital
Resources."

                                    DILUTION
 
   
     The Company's net tangible book value at September 30, 1996 was
$37,404,000, or approximately $1.91 per share of Common Stock. Net tangible book
value per share represents the amount of total tangible assets of the Company
reduced by the amount of the Company's total liabilities, divided by the number
of shares of Common Stock outstanding. After giving effect to the Company's
receipt of the estimated net proceeds from the sale of 12,500,000 shares of
Common Stock in this offering at an assumed initial public offering price of
$10.50 per share, the Company's pro forma as adjusted net tangible book value as
of September 30, 1996 would have been $159,176,000, or $4.97 per share. This
represents an immediate increase in pro forma net tangible book value of $3.06
per share to the Company's stockholders and an immediate dilution in pro forma
net tangible book value of $5.53 per share to new investors purchasing shares in
this offering. The following table illustrates the per share dilution in pro
forma net tangible book value to new investors:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
   
     Titan is an independent energy company engaged in the exploration,
development and acquisition of oil and gas properties. The Company's strategy is
to grow reserves, production and net income per share through (i) the
acquisition of producing properties that provide significant development and
exploratory drilling potential, (ii) the exploitation and development of its
reserve base, (iii) the exploration for oil and gas reserves and (iv) the
implementation of a low operating and overhead structure. The Company has grown
rapidly through the acquisition and exploitation of oil and gas properties,
consummating the 1995 Acquisition for a purchase price of approximately $40.6
million and the 1996 Acquisition for approximately $135.5 million.
    
 
   
     The Company's growth resulting from acquisitions has impacted its reported
financial results in a number of ways. Acquired properties frequently have not
received focused attention prior to sale. After acquisition, certain of these
properties require maintenance, workovers, recompletions and other remedial
activity not constituting capital expenditures, which initially serves to
increase lease operating expenses. The Company anticipates spending at least
$1.0 million in nonrecurring maintenance expenses with respect to the properties
obtained in the 1996 Acquisition. The Company may dispose of certain of the
properties if it determines they are outside the Company's strategic focus. The
increased production and revenue resulting from the rapid growth of the Company
has required it to recruit and develop operating, accounting and administrative
personnel compatible with its increased size. The Company believes that as a
result of the 1996 Acquisition it will need to employ 20 to 25 new employees, in
addition to its 20 employees at September 30, 1996. As a result, the Company
anticipates a corresponding increase in its general and administrative expense.
The Company believes that with its current inventory of drilling locations and
the anticipated additional staff it will be well positioned to follow a more
balanced program of exploration and exploitation activities to complement its
acquisition efforts.
    
 
     Titan uses the successful efforts method of accounting for its oil and gas
producing activities. Costs to acquire mineral interests in oil and gas
properties, to drill and equip exploratory wells that result in proved reserves,
and to drill and equip development wells are capitalized. Costs to drill
exploratory wells that do not result in proved reserves, geological and
geophysical costs, and costs of carrying and retaining properties that do not
contain proved reserves are expensed. Costs of significant nonproducing
properties, wells in the process of being drilled and significant development
projects are excluded from depletion until such time as the related project is
developed and proved reserves are established or impairment is determined.
 
   
     The Company's predecessor was classified as a partnership for federal
income tax purposes. Therefore, no income taxes were paid by the Company prior
to the Conversion. Future tax amounts, if any, will be dependent upon several
factors, including, but not limited to, the Company's results of operations.
    
 
RESULTS OF OPERATIONS
 
   
     The financial statements of the Company, which began operations on March
31, 1995, include the results of the nine months ended December 31, 1995 and the
nine months ended September 30, 1996. As a result of the Company's limited
operating history and rapid growth, its financial statements are not readily
comparable and may not be indicative of future results. Furthermore, because the
period from inception of the Company to September 30, 1995 was only six months
in length, a comparison of results from that period to the nine months ended
September 30, 1996 would not be meaningful.
    
 
   
  Nine Months Ended September 30, 1996
    
 
   
     For the nine months ended September 30, 1996, the Company's revenues from
the sale of oil and gas (excluding the effects of hedging activities) were $7.6
million and $4.1 million, respectively. During the period, the Company produced
388 MBbls of oil and 2,725 MMcf of gas, with total oil and gas production of 842
MBOE. The revenues and production are primarily attributable to the 1995
Acquisition.
    
 
                                       19
<PAGE>   22
 
   
     As a result of hedging activities in the nine months ended September 30,
1996, oil revenues were reduced $899,000 ($2.32 per Bbl) to $17.25 per Bbl and
gas revenues were reduced $553,000 ($.20 per Mcf) to $1.30 per Mcf for a total
reduction of $1,452,000.
    
 
   
     Oil and gas production costs, including production taxes, were $4.3 million
($5.15 per BOE) for the nine months ended September 30, 1996. These costs
included $645,000 ($.77 per BOE) that were attributable to rework expenses
incurred with respect to the 1995 Acquisition properties.
    
 
   
     Exploration and abandonment costs were $110,000 for the nine months ended
September 30, 1996.
    
 
   
     General and administrative expenses were $1,452,000 ($1.72 per BOE) for the
nine months ended September 30, 1996.
    
 
   
     For the nine months ended September 30, 1996, depletion, depreciation and
amortization expense was $2.3 million ($2.69 per BOE), which primarily
represents the depletion, depreciation and amortization relating to the
production from the 1995 Acquisition.
    
 
   
     Interest expense was $1,179,000 for the nine months ended September 30,
1996. The interest expense was attributable to bank financing incurred to fund
the 1995 Acquisition.
    
 
  Nine Months Ended December 31, 1995
 
   
     For the nine months ended December 31, 1995, the Company's revenues from
the sale of oil and gas were $504,000 and $239,000, respectively. During the
period, the Company produced 30 MBbls of oil and 245 MMcf of gas, for a total
production of 71 MBOE. The revenues and production are primarily attributable to
the 1995 Acquisition which was consummated December 11, 1995.
    
 
     Oil and gas production costs, including production taxes, were $304,000
($4.28 per BOE) for the nine months ended December 31, 1995.
 
     Exploration and abandonment costs were $490,000 for the nine months ended
December 31, 1995.
 
     General and administrative expenses were $1.5 million ($21.77 per BOE) for
the nine months ended December 31, 1995.
 
     For the nine months ended December 31, 1995, depletion, depreciation and
amortization expense was $299,000 ($4.21 per BOE).
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Capital Sources
 
     Funding for the Company's business activities has been provided by its
initial capitalization, bank financing, cash flow from operations and private
equity sales. The 1995 Acquisition was funded with cash from the Company's
initial capitalization, additional private equity sales and bank financing. The
1996 Acquisition was funded with bank financing to be partially repaid with the
proceeds of this offering and the issuance of equity capital in a private
placement in September 1996.
 
   
     While the Company regularly engages in discussions relating to potential
acquisitions of oil and gas properties, the Company has no present agreement,
commitment or understanding with respect to any such acquisition, other than the
acquisition of oil and gas properties and interests in its normal course of
business. Any future acquisitions may require additional financing and will be
dependent upon financing arrangements available at the time.
    
 
   
     The Company believes that in the short-term -- that is, through
1997 -- availability under the Credit Agreement and cash flow from operations
will be sufficient for anticipated operating and capital expenditure
requirements in 1997. Immediately following the completion of this offering, the
Company expects to have approximately $142.1 million available under the Credit
Agreement. However, in the long term -- beyond 1997 -- if the Company's cash
flow from operations and availability under the Credit Agreement are not
    
 
                                       20
<PAGE>   23
 
   
sufficient to satisfy cash requirements, there can be no assurance that
additional debt or equity financing will be available to meet its requirements.
    
 
     Although certain of the Company's costs and expenses may be affected by
inflation, inflationary costs have not had a significant effect on the Company's
results of operations.
 
   
     Net Cash Provided by (Used in) Operating Activities. For the nine months
ended December 31, 1995, net cash used in operations was $1.8 million primarily
due to initiation of the Company's operations. For the nine months ended
September 30, 1996, net cash provided by operating activities increased to $5.7
million due primarily to the 1995 Acquisition and the cash flow therefrom.
    
 
   
     Net Cash Used in Investing Activities. For the nine months ended December
31, 1995, net cash used in investing activities was $47.6 million of which $39.9
million was primarily attributable to the 1995 Acquisition. An additional $3.8
million was expended in other acquisition, exploration and development
activities, along with the purchase of a $5.0 million short-term investment. Net
cash used in investing activities for the nine months ended September 30, 1996
was $12.8 million, which was the result of the redemption of $5.0 million in
short-term investments, additions to oil and gas properties of $17.6 million and
additions of $200,000 to other property and equipment.
    
 
   
     Net Cash Provided by Financing Activities. Net cash provided by financing
activities was $55.5 million for the nine months ended December 31, 1995. This
included $20.0 million of proceeds from the issuance of long-term debt and $35.5
million of capital contributions. For the nine months ended September 30, 1996,
net cash provided by financing activities was $11.7 million, which included $8.0
million from the issuance of long-term debt and $3.7 million from capital
contributions.
    
 
   
     Credit Agreement. The Credit Agreement establishes a four year revolving
credit facility, up to the maximum amount of $250 million, subject to a
borrowing base to be determined annually by the lenders based on certain proved
oil and gas reserves and other assets of the Company. Initially, the borrowing
base is established at $165 million. To the extent that the borrowing base is
less than the aggregate principal amount of all outstanding loans and letters of
credit under the Credit Agreement, such deficiency must be cured by the Company
ratably within 180 days, by either prepaying a portion of the outstanding
amounts under the Credit Agreement or pledging additional collateral to the
lenders. A portion of the credit facility is available for the issuance of up to
$15.0 million of letters of credit including $2.0 million outstanding at
September 30, 1996. The Company borrowed $154.5 million of the $165 million
available under the Credit Agreement at the closing of the 1996 Acquisition.
Pending other uses of the net proceeds of this offering, the Company intends to
use the net proceeds to repay indebtedness under the Credit Agreement. See "Use
of Proceeds."
    
 
     All outstanding amounts under the Credit Agreement are due and payable in
full on January 1, 2001.
 
   
     At the Company's option, borrowings under the Credit Agreement bear
interest at either (i) the "Base Rate" (i.e., the higher of the applicable prime
commercial lending rate, or the federal funds rate plus .5% per annum) or (ii)
the Eurodollar rate plus a margin ranging from 1% to 1.50% per annum that
depends on the level of the Company's aggregate outstanding borrowings under the
Credit Agreement. In addition, the Company is committed to pay quarterly in
arrears a fee ranging from .30% to .375% of the unused portion of the borrowing
base.
    
 
   
     The loan documents governing the Credit Agreement contain certain covenants
and restrictions relating to the Company's operations that are customary in the
oil and gas industry. In addition, the line of credit is secured by a first lien
on properties that represented at least 80% of the value of the Company's proved
oil and gas properties (based on PV-10 as of September 30, 1996).
    
 
  Capital Expenditures
 
     The Company requires capital primarily for the exploration, development and
acquisition of oil and gas properties, the repayment of indebtedness and general
working capital needs.

OTHER MATTERS
 
  Stock Options and Compensation Expense
 
     In connection with the Conversion, the Company issued options to purchase
3,631,350 shares of Common Stock to certain of its officers and employees in
substitution for options issued by the Partnership. Of the options issued by the
Partnership, approximately 93% were issued on March 31, 1995, the date of
inception, and approximately 7% were issued as of September 1, 1996. The options
issued by the Company have an exercise price of $2.08 per share. Options to
purchase 803,576 shares of Common Stock are currently vested and an additional
1,190,841, 1,209,966 and 426,967 shares will vest on March 31 of each of 1997,
1998 and 1999, respectively. Based in part on selling prices of interests in the
Partnership in December 1995 and September 1996, the Company expects to record a
noncash compensation expense of approximately $579,000 per month for a period of
30 months beginning in the fourth quarter of 1996 to reflect the estimated value
of the revised option plan on September 30, 1996.
 
  Hedging Activities
 
   
     The Company uses swap agreements in an attempt to reduce the risk of
fluctuating oil and gas prices and interest rates. In November and December
1995, the Company entered into four master agreements for energy price and other
swap transactions with each of Enron Capital & Trade Resources Corp. ("ECTRC")
(an affiliate of Joint Energy Development Investments Limited Partnership
("JEDI"), an owner of in excess of 5% of the outstanding Common Stock), First
Union National Bank of North Carolina (a lender to the Company under the Credit
Agreement and an affiliate of First Union Corporation, an owner of in excess of
5% of the outstanding Common Stock), Chemical Bank and Texas Commerce Bank
National Association (a lender to the Company and an affiliate of Chemical
Bank). The Company has entered into energy price swap arrangements from time to
time under these master agreements. Settlement of gains or losses on these
energy swap transactions is generally based on the difference between the
contract price and a formula using New York Mercantile Exchange ("NYMEX")
related prices and is reported as a component of oil and gas revenues as the
associated production occurs. The Company has entered into hedging transactions
with respect to a substantial portion of its estimated production through
December 1996, excluding the production attributable to the 1996 Acquisition.
The Company's reserve report at September 30, 1996 reflects hedging activities
contracted through December 31, 1996, resulting in a reduction of PV-10 of
$420,000. The Company continues to evaluate whether to enter into additional
hedging transactions for 1997 and future years. The following is a summary of
the Company's hedging transactions in effect as of September 30, 1996. See "Risk
Factors -- Risk of Hedging Activities."
    
 
   
     Natural Gas. As of September 30, 1996, the Company had hedging transactions
related to 220,000 MMBtu of natural gas per month through December 1996 that
provide for settlements based on prices of natural gas determined by reference
to closing prices of natural gas futures contracts traded on NYMEX. These hedges
include a price swap using a "participating floor" with a price of $1.70 per
MMBtu. In the event that the NYMEX reference price for any settlement period is
less than the floor price, the
    
 
                                       22
<PAGE>   25
 
   
Company will be paid 100% of the difference. In the event that the NYMEX
reference price for any settlement period is greater than the floor price, the
Company must pay 47% of the difference.
    
 
   
     Since most of the Company's natural gas is sold under spot contracts with
reference to El Paso Permian Basin sales hub prices, the Company entered into
"basis differential swaps" related to 220,000 MMBtu of natural gas per month for
the period May 1996 through December 1996. In the event that the NYMEX reference
price for a reference period exceeds the average price per MMBtu for natural gas
delivered to El Paso Permian Basin hub by more than $.325 per MMBtu the Company
receives a payment based on the excess above the $.325 basis. In the event that
the NYMEX reference price for a reference period exceeds the El Paso Permian hub
price by less than $.325 per MMBtu (or in the event that the El Paso Permian
Basin hub price exceeds the NYMEX reference price), the Company must pay the
deficiency below the $.325 basis.
    
 
   
     As a result of its hedging activities, the Company's natural gas revenues
were reduced by $553,000 for the nine months ended September 30, 1996.
    
 
   
     Crude Oil. As of September 30, 1996, the Company had one hedging
transaction related to 25,000 Bbls of West Texas Intermediate Light Sweet crude
oil a month through December 1996 that provides for settlements based on prices
of oil determined by reference to NYMEX future oil contracts. The swap price for
this transaction is $17.18 per Bbl. In the event that the NYMEX reference price
for any settlement period is less than the swap price, the Company receives the
difference. In the event that the NYMEX reference price for any settlement
period is greater than the swap price, the Company must pay the difference.
    
 
   
     As a result of its hedging activities, the Company's crude oil revenues
were reduced by $899,000 during the nine months ended September 30, 1996.
    
 
     Interest Rates. The Company also uses derivative financial instruments to
manage interest rate risks. Under an interest rate swap agreement, the Company
has an effective rate of 6.72% on $10 million of its revolving line of credit
through December 23, 1996.
 
  Natural Gas Balancing
 
   
     It is customary in the natural gas industry for various working interest
partners to produce more or less than their entitlement share of natural gas
from time to time. The Company's net overproduced position at September 30, 1996
was 549,844 Mcf, and 205,182 Mcf on a pro forma basis. Under terms of typical
natural gas balancing agreements, the underproduced party can take a certain
percentage, typically 25% to 50% of the overproduced party's entitled share of
gas sales in future months, to eliminate such imbalances. During the make-up
period, the overproduced party's cash flow will be adversely affected. The
Company recognizes revenue and imbalance obligations under the entitlements
method of accounting.
    
 
   
  Environmental and Other Laws and Regulations
    
 
   
     The Company's business is subject to certain federal, state and local laws
and regulations relating to the exploration for and the development, production
and transportation of oil and gas, as well as environmental and safety matters.
Many of these laws and regulations have become more stringent in recent years,
often imposing greater liability on a larger number of potentially responsible
parties. Although the Company believes it is in substantial compliance with all
applicable laws and regulations, the requirements imposed by such laws and
regulations are frequently changed and subject to interpretation, and the
Company is unable to predict the ultimate cost of compliance with these
requirements or their effect on its operations. The Company has no material
commitments for capital expenditures to comply with existing environmental
requirements. Nevertheless, changes in existing environmental laws or in
interpretations thereof could have a significant impact on the operating costs
of the Company, as well as the oil and gas industry in general. See "Risk
Factors -- Compliance with Environmental Regulations," "Business and
Properties -- Environmental Matters" and "Business and Properties -- Abandonment
Costs."

  Accounting Pronouncements
 
   
     On October 23, 1995, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation," which establishes a fair value method for accounting for
stock-based compensation plans either through recognition or disclosure. The
Company adopted this standard in 1996 and will disclose the pro forma net income
(loss) and earnings (loss) per share amounts assuming the fair value method was
adopted on March 31, 1995 (date of inception) in its financial statements as of
and for the year ended December 31, 1996. The adoption of this standard will not

                            BUSINESS AND PROPERTIES
GENERAL
 
   
     Titan is an independent energy company engaged in the exploration,
development and acquisition of oil and gas properties. Since its inception in
March 1995, the Company has experienced significant growth in reserves,
production and cash flow by acquiring and exploiting producing properties
primarily in the Permian Basin of west Texas and southeastern New Mexico.
    
 
   
     In December 1995, the Company acquired a concentrated group of Permian
Basin producing oil and gas properties from a large independent company for
approximately $40.6 million (the "1995 Acquisition"). On October 31, 1996, the
Company acquired additional Permian Basin producing properties from a major
integrated company for approximately $135.5 million (the "1996 Acquisition"). As
of September 30, 1996, the Company had pro forma estimated net proved reserves
of approximately 17.8 MMBbls of oil and 280.8 Bcf of natural gas, or an
aggregate of 64.6 MMBOE with a PV-10 of $292.1 million. If, in calculating the
PV-10, the Company's oil and gas prices at October 31, 1996 were substituted for
the prices at September 30, 1996, the PV-10 would be $351.9 million. The prices
of the Company's oil decreased 4% and gas increased 33%, respectively, from
September 30, 1996 to October 31, 1996. Approximately 62% of these reserves were
classified as proved developed. The Company acquired, explored for and developed
its reserves for an average reserve replacement cost of approximately $2.73 per
BOE through September 30, 1996, assuming the 1996 Acquisition was consummated on
September 30, 1996. Pro forma production for the nine months ended September 30,
1996 was 12,227 BOE per day, resulting in an annualized pro forma proved
reserves to production ratio of 14.5 to one.
    
 
   
     The Company prefers to acquire properties over which it can exercise
operating control. The Company operated 456 gross wells (389 net wells) on a pro
forma basis at September 30, 1996, and these operated properties represented
approximately 71% of its pro forma proved developed producing PV-10 and 83% of
the Company's pro forma proved PV-10 at September 30, 1996. The Company's
emphasis on controlling the operation of its properties enables the Company to
manage expenses, capital allocation and other aspects of development and
exploration.
    
 
   
     The Company's oil and gas properties are located in 57 fields in the
Permian Basin, one of the most prolific oil and gas producing regions in North
America. Approximately 70% of the Company's PV-10 of total proved reserves is
concentrated in 12 principal fields located in this region. The region is
characterized by complex geology with numerous known producing horizons and
provides significant opportunities to increase reserves, production and ultimate
recoveries through development, exploratory and horizontal drilling,
recompletions, secondary and tertiary recovery methods, and use of 3-D seismic
and other advanced technologies.
    
 
   
     The Company believes that its personnel provide it with competitive
advantages for exploiting these opportunities in the Permian Basin and other
complex producing basins in North America. Members of the Company's management
team have an average of 25 years experience in the oil and gas industry and have
operating experience in all aspects of the industry, in particular deep well and
horizontal drilling. They have formulated and supervised acquisitions,
exploration projects, development drilling programs and production enhancement
plans, including workovers and enhanced recovery projects. In addition,
management has a significant equity investment in the Company. Giving effect to
this offering and assuming the exercise by management of all of their options to
acquire Common Stock, management will beneficially own an aggregate of 20% of
the Company's outstanding Common Stock.
    
 
                               BUSINESS STRATEGY
 
   
     The Company's strategy is to grow reserves, production and net income per
share through (i) the acquisition of producing properties that provide
significant development and exploratory drilling potential, (ii) the
exploitation and development of its reserve base, (iii) the exploration for oil
and gas reserves and (iv) the implementation of a low operating and overhead
cost structure.
    
 
                                       25
<PAGE>   28
 
   
    - Acquisitions. The Company seeks to acquire oil and gas properties that
      provide opportunities for the addition of reserves, production and value
      through low risk exploitation and development, high-potential exploration
      and control of operations. The Company believes that these criteria can be
      met in the Permian Basin and in other North American basins have high
      historical cumulative production levels that represent a relatively small
      percentage of the recoverable in-place reserves. At September 30, 1996,
      the Company had acquired and developed 64.6 MMBOE of proved oil and gas
      reserves at an average reserve replacement cost of $2.73 per BOE, assuming
      the 1996 acquisition was consummated on September 30, 1996, which compares
      to an average reserve replacement cost of $4.85 per BOE (for 1993 through
      1995) for the 184 independent oil and gas companies included in the Arthur
      Andersen 1996 Oil and Gas Reserve Disclosures.
    
 
   
    - Exploitation of Reserve Base. The Company engages in horizontal and
      infill drilling activities, major workovers, recompletions, secondary and
      tertiary recovery operations, and other production enhancement techniques
      in order to increase reserves and production. On a pro forma basis, the
      Company has identified 53 drilling locations on Company-operated
      properties, which include 14 proved locations and 39 unproven locations.
      In drilling a portion of these wells in 1997, the Company expects to spend
      approximately $12.9 million to develop proved locations and $6.8 million
      to develop unproven locations. The Company has also identified an
      additional 90 unproven drilling locations on Company-owned, but
      nonoperated, properties.
    
 
    - Exploration Activities. The Company seeks to apply management's extensive
      geological and drilling expertise and 3-D seismic technology to identify
      and develop exploration projects. As part of its exploration strategy, the
      Company attempts to reduce the costs and risks of its exploration
      activities by, in selected circumstances, applying 3-D seismic technology,
      drilling wells with multiple pay objectives in known producing areas and
      selling interests in its exploration prospects to industry partners. A
      large portion of the Company's efforts have focused on deep well
      opportunities in historically prolific fields.
 
   
    - Low Cost Structure. The Company has implemented and plans to maintain a
      low overhead and operating cost structure to enhance the profitability and
      the exploitation potential of its properties. The Company provides
      incentive stock awards to its senior management team in lieu of
      comparatively higher salary levels in order to align management's
      interests with stockholders, maintain relatively low general and
      administrative expense levels and increase the amount of cash flow
      available for reinvestment by the Company. The Company also seeks to be an
      efficient operator and achieve reductions in labor and other field-level
      costs from those incurred by previous operators of its properties. By
      operating a significant portion of its daily production, the Company
      believes it is well positioned to control the expenses and timing of
      development and exploitation of such properties and to better manage such
      cost reduction efforts.
    
 
   
COMPANY HISTORY
    
 
     The history of the Company's operations can be divided into three segments:
 
   
     Initial Operations. The Company was formed in March 1995 by Jack Hightower,
members of his management team and Natural Gas Partners, L.P. and Natural Gas
Partners II, L.P. (collectively, "NGP"), with an initial equity capitalization
of approximately $20.5 million. From its inception, the Company engaged in the
exploration, development and acquisition of oil and gas properties, initially
focusing on those in Ward, Pecos, Winkler and Hardeman counties in Texas. From
inception until December 31, 1995, excluding the 1995 Acquisition, the Company
spent approximately $2.7 million to acquire and develop properties in these
counties. From January 1, 1996 until September 30, 1996, the Company spent an
additional $5.9 million to further develop these properties. This activity has
resulted in a PV-10 attributable to these initial properties of approximately
$53.6 million at September 30, 1996.
    
 
     1995 Acquisition. On December 11, 1995, the Company acquired a concentrated
group of producing oil and gas properties in the Permian Basin from a large,
independent exploration and production company for a purchase price of
approximately $40.6 million. The 1995 Acquisition was financed principally
through cash from the initial capitalization of the Company and borrowings under
the Credit Agreement, which at that time
 
                                       26
<PAGE>   29
 
   
had a $35 million borrowing base. From the consummation of the 1995 Acquisition
through September 30, 1996, the Company spent a total of approximately $4.3
million to acquire additional working interests and develop and enhance these
properties and has received net cash flow of approximately $7.2 million. As of
September 30, 1996, these properties, net to the Company, had an estimated 22.9
MMBOE of reserves and a PV-10 of $90.9 million.
    
 
   
     1996 Acquisition. On October 31, 1996, the Company acquired leasehold
interests in certain oil and gas producing fields situated in the Permian Basin
from a major integrated oil and gas company for a purchase price of
approximately $135.5 million. The 1996 Acquisition was financed with
indebtedness under the Credit Agreement and proceeds from the issuance of equity
in a private placement in September 1996. Pending other uses, the net proceeds
from this offering will be used primarily to reduce indebtedness under the
Credit Agreement. See "Use of Proceeds." As of September 30, 1996, these
properties had an estimated 28.2 MMBOE of reserves and a PV-10 of $147.5
million.
    
 
ACQUISITIONS
 
     The Company regularly pursues and evaluates acquisition opportunities
(including opportunities to acquire oil and gas properties or related assets or
entities owning oil and gas properties or related assets and opportunities to
engage in mergers, consolidations or other business combinations with entities
owning oil and gas properties or related assets) and at any given time may be in
various stages of evaluating such opportunities. Such stages may take the form
of internal financial and oil and gas property analysis, preliminary due
diligence, the submission of an indication of interest, preliminary
negotiations, negotiation of a letter of intent or negotiation of a definitive
agreement. While the Company is currently evaluating a number of potential
acquisition opportunities (some of which would be material in size to the
Company), it has not signed a letter of intent with respect to any material
acquisition and currently has no assurance of completing any particular material
acquisition or of entering into negotiations with respect to any particular
material acquisition.
 
PRINCIPAL OIL AND GAS PROPERTIES
 
   
     Approximately 46% of the Company's PV-10 of total proved reserves is
concentrated in six principal fields, the Puckett, Dollarhide East, Foster, Mi
Vida, Barstow and North Robertson fields. In addition, approximately 24% of the
Company's PV-10 of total proved reserves is concentrated in six other fields,
the Gomez, University Waddell, Sand Hills, Evetts, Headlee and Petco. A
description of each of these 12 fields is set forth below. Cumulative field
production data is as of June 30, 1996 and may not include field production data
prior to 1966.
    
 
   
     Puckett Field. The Company owns 1,280 gross leasehold acres (1,120 net
leasehold acres) in the Puckett Field in Pecos County, Texas. The Company's
working interests in this acreage range from 74% to 100%, and the Company
operates 100% of its PV-10 in this field. The primary producing formations in
the field are the Ellenburger and Devonian, which range from depths of 11,500
feet to 15,000 feet. Cumulative field production from these formations has been
3.4 Tcf and 464 Bcf, respectively. The Company's acreage has produced 207 Bcf
and 67 Bcf, respectively, from three wellbores in these formations. The Company
has identified two proved Ellenburger horizontal drilling replacement locations,
one of which is currently drilling. The Company has also identified one workover
opportunity in the Devonian formation, as well as a recompletion opportunity in
the Fusselman formation.
    
 
   
     Dollarhide East Field. The Company owns approximately 2,500 gross leasehold
acres (approximately 2,200 net leasehold acres) in the Dollarhide East Field in
Andrews County, Texas. The Company's working interests in this field range from
69% to 100%, and the Company operates 100% of its PV-10 in this field. The
primary producing formations in the field are the Devonian, Silurian and
Ellenburger, which range from depths of 11,000 feet to 12,700 feet. Cumulative
field production from these formations has been 8.2 MMBbls, 1.3 MMBbls and 6.2
MMBbls, respectively. The Company will use existing 3-D seismic to plan
expansion of an existing waterflood program and analyze the potential for
tertiary recovery operations. Although no proved
    
 
                                       27
<PAGE>   30
 
   
reserves have been attributed to tertiary operations on the Company's acreage,
tertiary recovery operations have been underway on an adjacent analogous field
since 1986.
    
 
   
     Foster Field. The Company owns 6,280 gross leasehold acres (3,820 net
leasehold acres) in the Foster Field in Ector County, Texas. The Company's
interests in this field include a 19% working interest in the Amoco-operated
South Foster unit, a 40% working interest in the Conoco-operated Gist unit and
an 80% working interest in the Company-operated North Foster unit. The primary
producing formation in the field is the Grayburg at a maximum depth of 4,800
feet, with cumulative production in the field of 291 MMBbls.
    
 
     Waterflood programs are underway on all three interests. The Company is
studying the economic feasibility of a tertiary recovery project in this field.
In the North Foster unit, the Company has identified four unproven drilling
locations to be defined further with 3-D seismic and five refracture stimulation
opportunities. Contingent on the success of the drilling of the four unproven
locations, the Company could drill 12 additional unproven locations.
 
   
     Mi Vida Field. The Company owns approximately 5,900 gross leasehold acres
(approximately 4,300 net leasehold acres) in the Mi Vida Field in Ward County,
Texas. The Company's working interests in this field range from 54% to 98%, and
the Company operates 100% of its PV-10 in this field. The primary producing
formations in the field are the Fusselman, Ellenburger and Penn, which range
from depths of 14,500 feet to 19,100 feet. Cumulative field production from
these formations has been 740 Bcf, 181 Bcf and 6.0 Bcf, respectively.
    
 
     The Company's plans include the installation of gas-lift equipment on three
wells and acquiring 3-D seismic on the entire field to identify infill, step-out
and sidetrack drilling opportunities. Subject to verification by the 3-D
seismic, the Company has identified four unproven sidetrack opportunities.
 
   
     Barstow Field. The Company owns 2,315 gross leasehold acres (1,604 net
leasehold acres) in the Barstow Field in Ward County, Texas. The Company's
working interests in this field range from approximately 45% to 80%, and the
Company operates 100% of its PV-10 in this field. The primary producing
formations in the field are the Fusselman and Ellenburger, which range from
depths of 18,000 feet to 19,700 feet. Cumulative field production from these
formations has been 221 Bcf and 17 Bcf, respectively.
    
 
     The Company completed a well in the Fusselman formation early in 1996. As
anticipated by the Company, bottom-hole pressure data indicated that a portion
of the field had repressurized since having been shut-in in 1981. Subsequently,
the Company conducted a 3-D seismic survey that identified two proved
undeveloped drilling locations. The first of those was spudded August 31, 1996.
The second well is planned for drilling in 1997. In addition, based on analysis
of the 3-D seismic, the Company has identified an exploratory drilling location
targeting the Ellenburger and Fusselman formations.
 
   
     North Robertson Field. The Company owns approximately 5,400 gross leasehold
acres (approximately 860 net leasehold acres) in the North Robertson Field in
Gaines County, Texas. The Company's working interest in the North Robertson unit
is 16%. The primary producing formation in the unit is the Clearfork at a
maximum depth of 7,200 feet with cumulative field production of 111 MMBbls and
62 Bcf of gas.
    
 
     The Company anticipates participating in 60 unproven 10-acre infill
development wells in the North Robertson Clearfork unit. Contingent on the
success of this infill program, the Company believes an additional 30 locations
could be drilled.
 
     Gomez Field. The Company owns 2,490 gross leasehold acres (830 net
leasehold acres) in the Gomez Field in Pecos County, Texas. The Company's
working interests in this field range from 23% to 100%, and the Company operates
approximately 80% of its PV-10 in this field. The primary producing formations
in the field are the Ellenburger and Wolfcamp, which range from depths of 11,100
feet to 22,600 feet. Cumulative field production from these formations has been
4.7 Tcf and 54 Bcf with 3.8 MMBC, respectively.
 
   
     University Waddell Field. The Company currently owns approximately 1,200
gross leasehold acres (approximately 1,100 net leasehold acres) in the
University Waddell Field in Crane County, Texas. The Company's working interest
in the University Waddell Devonian Unit is 89.51% and the Company operates 100%
of its PV-10 in this field. The primary producing formation in the field is the
Devonian to a maximum
    
 
                                       28
<PAGE>   31
 
depth of 9,000 feet. Cumulative production from the unit has been approximately
19.3 Bcf of gas and 9.4 MMBbls of oil. Total field production from the Devonian
formation is approximately 67 MMBbls and 115 Bcf. The Company believes that by
altering the injection pattern and rates of the existing waterflood program it
can improve recoveries beyond the estimated remaining proved reserves on the
Company's properties in the field. The Company is studying the feasibility of
secondary recovery enhancements and tertiary recovery opportunities.
 
   
     Sand Hills Field. The Company currently owns approximately 9,100 gross
leasehold acres (approximately 9,100 net leasehold acres) in the Sand Hills
Field in Crane County, Texas. The Company has a 100% working interest in this
acreage, and the Company operates 100% of its PV-10 in this field. The primary
producing formations in the field are the Judkins, McKnight, San Angelo and
Tubb, which range from depths of 2,800 feet to 4,200 feet. Cumulative field gas
production from these formations has been 1.1 Tcf, 561 Bcf, 40 Bcf and 228 Bcf,
respectively. In addition, cumulative oil production from the Judkins, McKnight
and Tubb formations in the field has been 12 MMBbls, 125 MMBbls and 96 MMBbls,
respectively.
    
 
   
     Evetts Field. The Company owns 1,280 gross leasehold acres (724 net
leasehold acres) in the Evetts Field in Winkler County, Texas. The Company's
working interests in this field range from 3% to 91%, and the Company operates
approximately 84% of its PV-10 in this field. In addition, the Company has an
approximate 4.28% working interest in the balance of the field, which is
operated by another company. The primary producing formations in the field are
the Ellenburger, Silurian and Penn, which range from depths of 15,500 feet to
20,800 feet. Cumulative field production from these formations has been 82 Bcf,
653 Bcf and 35 Bcf, respectively.
    
 
     In this field, the Company has identified one proved undeveloped location
in the Silurian formation. The Company will conduct a 3-D seismic survey to
optimize this location. The Company has identified one unproven drilling
location targeting the Atoka formation and four unproven drilling locations
targeting the Bone Spring formation. The Company has identified these locations
using data gathered from wells directly offsetting the proposed locations.
 
   
     Headlee Field. The Company currently owns approximately 16,000 gross
leasehold acres (approximately 460 net leasehold acres) in the Headlee Field in
Ector County, Texas. The Company has a 2.91% working interest in the Headlee
Devonian Unit. Since 1989, a gas blowdown in the unit has produced 388 Bcf.
    
 
     Petco Field. The Company currently owns 2,560 gross leasehold acres (1,632
net leasehold acres) in the Petco Field in Pecos County, Texas. The Company's
working interests in this acreage range from 60% to 75%, and the Company
operates 100% of its PV-10 in this field. The primary producing formations in
the field are the Devonian and the Ellenburger, which range from depths of
11,000 feet to 13,700 feet. Cumulative field natural gas production from these
formations has been 13 Bcf and 9.5 Bcf, respectively. In the second quarter of
1996, the Company conducted a 3-D seismic survey covering 15 square miles of the
Petco field. Based on analysis of this seismic and production data and extensive
studies of subsurface mapping and dipmeters, the Company has identified a proved
undeveloped location on its acreage with a planned dual completion in the
Devonian and Ellenburger formations. The Company has also identified an
exploration prospect and plans to extend the 3-D seismic survey to further
delineate this and other potential prospects in the field.

would have received at the end of each reported period without escalation. The
average prices for the Company's reserves as of September 30, 1996 were $23.37
per Bbl of oil and $1.39 per Mcf of natural gas, compared to average prices for
the Company's reserves as of December 31, 1995 of $17.66 per Bbl and $1.38 per
Mcf.
    
 
     Estimated quantities of proved reserves and future net revenues therefrom
are affected by natural gas prices, which have fluctuated widely in recent
years. There are numerous uncertainties inherent in estimating oil and gas
reserves and their estimated values, including many factors beyond the control
of the producer. The reserve data set forth in this Prospectus represents only
estimates. Reservoir engineering is a subjective process of estimating
underground accumulations of oil and gas that cannot be measured in an exact
manner. The accuracy of any reserve estimate is a function of the quality of
available data and of engineering and geological interpretation and judgment. As
a result, estimates of different engineers, including those used by the Company,
may vary. In addition, estimates of reserves are subject to revision based upon
actual production, results of future development and exploration activities,
prevailing oil and gas prices, operating costs and other factors, which
revisions may be material. Accordingly, reserve estimates are often different
from the quantities of oil and gas that are ultimately recovered and are highly
dependent upon the accuracy of the assumptions upon which they are based. The
Company's estimated proved reserves have not been filed with or included in
reports to any federal agency. See "Risk Factors -- Uncertainty of Reserve
Information and Future Net Revenue Estimates."
 
   
     Estimates with respect to proved reserves that may be developed and
produced in the future are often based upon volumetric calculations and upon
analogy to similar types of reserves rather than actual production history.
Estimates based on these methods are generally less reliable than those based on
actual production history. Subsequent evaluation of the same reserves based upon
production history will result in variations, which may be substantial, in the
estimated reserves.

     Productive wells consist of producing wells and wells capable of
production, including gas wells awaiting pipeline connections. Wells that are
completed in more than one producing horizon are counted as one well. Of the
gross wells reported above, on a pro forma basis, nine had multiple completions.
 
  Acreage Data
 
     Undeveloped acreage includes leased acres on which wells have not been
drilled or completed to a point that would permit the production of commercial
quantities of oil and gas, regardless of whether or not such acreage contains
proved reserves. A gross acre is an acre in which an interest is owned. A net
acre is deemed to exist when the sum of fractional ownership interests in gross
acres equals one. The number of net acres is the sum of the fractional interests
owned in gross acres expressed as whole numbers and fractions thereof. The
following table sets forth the approximate developed and undeveloped acreage in
which the Company held a leasehold mineral or other interest at December 31,
1995 and, on a pro forma basis, at September 30, 1996.

OIL AND GAS MARKETING AND MAJOR CUSTOMERS
 
     The revenues generated by the Company's operations are highly dependent
upon the prices of, and demand for, oil and gas. The price received by the
Company for its oil and gas production depends on numerous factors beyond the
Company's control, including seasonality, the condition of the United States
economy, particularly the manufacturing sector, foreign imports, political
conditions in other oil-producing and gas-producing countries, the actions of
OPEC and domestic government regulation, legislation and policies. Decreases in
the prices of oil and natural gas could have an adverse effect on the carrying
value of the Company's proved reserves and the Company's revenues, profitability
and cash flow. Although the Company is not currently experiencing any
significant involuntary curtailment of its oil or gas production, market,
economic and regulatory factors may in the future materially affect the
Company's ability to sell its oil or gas production. See "Risk
Factors -- Volatility of Oil and Gas Prices" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
   
     For the nine months ended September 30, 1996, sales to Enron Corp., and its
subsidiaries and affiliates, were approximately 52% of the Company's oil and gas
revenues. See "Certain Transactions." Certain of these sales were based on six
month contracts for crude oil and month-to-month spot sales for natural gas.
    
 
     Due to the availability of other markets and pipeline connections, the
Company does not believe that the loss of any single crude oil or gas customer
would have a material adverse effect on the Company's results of operations.

COMPETITION
 
   
     The oil and gas industry is highly competitive. The Company encounters
competition from other oil and gas companies in all areas of its operations,
including the acquisition of producing properties. The Company's competitors
include major integrated oil and gas companies and numerous independent oil and
gas companies, individuals and drilling and income programs. Many of its
competitors are large, well established companies with substantially larger
operating staffs and greater capital resources than the Company and which, in
many instances, have been engaged in the energy business for a much longer time
than the Company. Such companies may be able to pay more for productive oil and
gas properties and exploratory prospects and to define, evaluate, bid for and
purchase a greater number of properties and prospects than the Company's
financial or human resources permit. The Company's ability to acquire additional
properties and to discover reserves in the future will be dependent upon its
ability to evaluate and select suitable properties and to consummate
transactions in a highly competitive environment. See "Risk
Factors -- Competition" and "Risk Factors -- Substantial Capital Requirements."
    
 
OPERATING HAZARDS AND UNINSURED RISKS
 
     Drilling activities are subject to many risks, including the risk that no
commercially productive reservoirs will be encountered. There can be no
assurance that new wells drilled by the Company will be productive or that the
Company will recover all or any portion of its investment. Drilling for oil and
gas may involve unprofitable efforts, not only from dry wells, but from wells
that are productive but do not produce sufficient net revenues to return a
profit after drilling, operating and other costs. The cost of drilling,
completing and operating wells is often uncertain. The Company's drilling
operations may be curtailed, delayed or canceled as a result of numerous
factors, many of which are beyond the Company's control, including title
problems, weather conditions, mechanical problems, compliance with governmental
requirements and shortages or delays in the delivery of equipment and services.
The Company's future drilling activities may not be successful and, if
unsuccessful, such failure may have a material adverse effect on the Company's
future results of operations and financial condition. See "Risk
Factors -- Drilling and Operating Risks."
 
     In addition, the Company's use of 3-D seismic requires greater pre-drilling
expenditures than traditional drilling strategies. Although the Company believes
that its use of 3-D seismic will increase the probability of success of its
exploratory wells and should reduce average finding costs through the
elimination of prospects that might otherwise be drilled solely on the basis of
2-D seismic data and other traditional methods, unsuccessful wells are likely to
occur. There can be no assurance that the Company's drilling program will be
successful or that unsuccessful drilling efforts will not have a material
adverse effect on the Company.
 
   
     The Company's operations are subject to hazards and risks inherent in
drilling for and producing and transporting oil and gas, such as fires, natural
disasters, explosions, encountering formations with abnormal pressures,
blowouts, cratering, pipeline ruptures and spills, any of which can result in
the loss of hydrocarbons, environmental pollution, personal injury claims and
other damage to properties of the Company and others.
    
 
     The Company expects to drill a number of deep vertical and horizontal wells
in the future. The Company's deep and/or horizontal drilling activities involve
greater risk of mechanical problems than other drilling operations. These wells
may be significantly more expensive to drill than those drilled to date.
 
   
     The Company maintains insurance against some, but not all, of the risks
described above. The Company may elect to self-insure in circumstances in which
management believes that the cost of insurance, although available, is excessive
relative to the risks presented. The occurrence of an event that is not covered,
or not fully covered, by insurance could have a material adverse effect on the
Company's financial condition and results of operations.
    
 
EMPLOYEES
 
   
     As of September 30, 1996, the Company had 20 full-time employees, none of
whom is represented by any labor union. Included in the total were 19 corporate
employees located in the Company's office in Midland, Texas, eight of whom are
devoted to the management of the Company. The Company plans to employ an
    
 
                                       33
<PAGE>   36
 
additional 20 to 25 employees as a result of the 1996 Acquisition. The Company
considers its relations with its employees to be good.
 
OTHER FACILITIES
 
     The Company currently leases approximately 12,905 square feet of office
space in Midland, Texas, where its principal offices are located. This office
lease is with an affiliate of Jack Hightower. See "Certain Transactions." The
Company's principal offices are leased through December 31, 1998. The Company
expects to lease additional space in the fourth quarter of 1996 and believes it
can obtain such space on commercially reasonable terms.
 
TITLE TO PROPERTIES
 
   
     The Company believes it has satisfactory title to all of its producing
properties in accordance with standards generally accepted in the oil and gas
industry. The Company's properties are subject to customary royalty interests,
liens incident to operating agreements, liens for current taxes and other
burdens which the Company believes do not materially interfere with the use of
or affect the value of such properties. The Company's Credit Agreement is
secured by a first lien on properties that represented at least 80% of the value
of the Company's proved oil and gas properties (based on PV-10 as of September
30, 1996).
    
 
GOVERNMENTAL REGULATION
 
   
     The Company's oil and gas exploration, production and related operations
are subject to extensive rules and regulations promulgated by federal and state
agencies. Failure to comply with such rules and regulations can result in
substantial penalties. The regulatory burden on the oil and gas industry
increases the Company's cost of doing business and affects its profitability.
Although the Company believes it is in substantial compliance with all
applicable laws and regulations, because such rules and regulations are
frequently amended or reinterpreted, the Company is unable to predict the future
cost or impact of complying with such laws.
    
 
     The State of Texas and many other states require permits for drilling
operations, drilling bonds and reports concerning operations and impose other
requirements relating to the exploration and production of oil and gas. Such
states also have statutes or regulations addressing conservation matters,
including provisions for the unitization or pooling of oil and gas properties,
the establishment of maximum rates of production from wells, and the regulation
of spacing, plugging and abandonment of such wells.
 
   
     The Federal Energy Regulatory Commission ("FERC") regulates interstate
natural gas transportation rates and service conditions, which affect the
marketing of gas produced by the Company, as well as the revenues received by
the Company for sales of such production. Since the mid-1980s, FERC has issued a
series of orders, culminating in Order Nos. 636, 636-A and 636-B ("Order 636"),
that have significantly altered the marketing and transportation of gas. Order
636 mandates a fundamental restructuring of interstate pipeline sales and
transportation service, including the unbundling by interstate pipelines of the
sale, transportation, storage and other components of the city-gate sales
services such pipelines previously performed. One of FERC's purposes in issuing
the orders is to increase competition within all phases of the gas industry.
Order 636 and subsequent FERC orders on rehearing have been appealed and are
pending judicial review. Because these orders may be modified as a result of the
appeals, it is difficult to predict the ultimate impact of the orders on the
Company and its gas marketing efforts. Generally, Order 636 has eliminated or
substantially reduced the interstate pipelines' traditional role as wholesalers
of natural gas, and has substantially increased competition and volatility in
natural gas markets.
    
 
   
     The price the Company receives from the sale of oil and natural gas liquids
is affected by the cost of transporting products to market. Effective January 1,
1995, FERC implemented regulations establishing an indexing system for
transportation rates for oil pipelines, which, generally, would index such rates
to inflation, subject to certain conditions and limitations. The Company is not
able to predict with certainty the effect, if any, of these regulations on its
operations. However, the regulations may increase transportation costs or
    
 
                                       34
<PAGE>   37
 
   
reduce wellhead prices for oil and natural gas liquids. See "Risk
Factors -- Compliance with Government Regulations."
    
 
ENVIRONMENTAL MATTERS
 
   
     The Company's operations and properties are subject to extensive and
changing federal, state and local laws and regulations relating to environmental
protection, including the generation, storage, handling, emission,
transportation and discharge of materials into the environment, and relating to
safety and health. The recent trend in environmental legislation and regulation
generally is toward stricter standards, and this trend will likely continue.
These laws and regulations may require the acquisition of a permit or other
authorization before construction or drilling commences and for certain other
activities; limit or prohibit construction, drilling and other activities on
certain lands lying within wilderness and other protected areas; and impose
substantial liabilities for pollution resulting from the Company's operations.
The permits required for various of the Company's operations are subject to
revocation, modification and renewal by issuing authorities. Governmental
authorities have the power to enforce compliance with their regulations, and
violations are subject to fines or injunction, or both. In the opinion of
management, the Company is in substantial compliance with current applicable
environmental laws and regulations, and the Company has no material commitments
for capital expenditures to comply with existing environmental requirements.
Nevertheless, changes in existing environmental laws and regulations or in
interpretations thereof could have a significant impact on the Company, as well
as the oil and gas industry in general. CERCLA and comparable state statutes
impose strict, joint and several liability on owners and operators of sites and
on persons who disposed of or arranged for the disposal of "hazardous
substances" found at such sites. It is not uncommon for neighboring landowners
and other third parties to file claims for personal injury and property damage
allegedly caused by the hazardous substances released into the environment. RCRA
and comparable state statutes govern the disposal of "solid waste" and
"hazardous waste" and authorize the imposition of substantial fines and
penalties for noncompliance. Although CERCLA currently excludes petroleum from
its definition of "hazardous substance," state laws affecting the Company's
operations impose clean-up liability relating to petroleum and petroleum related
products. In addition, although RCRA classifies certain oil field wastes as
"nonhazardous," such exploration and production wastes could be reclassified as
hazardous wastes thereby making such wastes subject to more stringent handling
and disposal requirements.
    
 
   
     The Company has acquired leasehold interests in numerous properties that
for many years have produced oil and gas. Although the previous owners of these
interests may have used operating and disposal practices that were standard in
the industry at the time, hydrocarbons or other wastes may have been disposed of
or released on or under the properties. In addition, some of the Company's
properties are operated by third parties over whom the Company has no control.
Notwithstanding the Company's lack of control over properties operated by
others, the failure of the operator to comply with applicable environmental
regulations may, in certain circumstances, adversely impact the Company. See
"Risk Factors -- Compliance with Environmental Regulations" and "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Other Matters."
    
 
   
ABANDONMENT COSTS
    
 
   
     The Company is responsible for payment of plugging and abandonment costs on
the oil and gas properties pro rata to its working interest. Based on its
experience, the Company anticipates that the ultimate aggregate salvage value of
lease and well equipment located on its properties will exceed the costs of
abandoning such properties. There can be no assurance, however, that the Company
will be successful in avoiding additional expenses in connection with the
abandonment of any of its properties. In addition, abandonment costs and their
timing may change due to many factors including actual production results,
inflation rates and changes in environmental laws and regulations.
    
 
LEGAL PROCEEDINGS
 
   
     The Company presently is not a party to any legal proceedings.

COMMITTEES OF THE BOARD
 
     Upon completion of this offering, the Company will establish two standing
committees of the Board of Directors: an Audit Committee and a Compensation
Committee. Messrs. Albin, Hersh and Vaughn are expected to be members of the
Audit Committee and Compensation Committee following completion of this
offering. The Audit Committee will review the functions of the Company's

Committee of the Board of Directors will recommend to the Board of Directors the

officers. The Board of Directors has designated the Compensation Committee as
the administrator of the Company's 1996 Incentive Plan. See "Management --

DIRECTOR COMPENSATION
 
     Directors who are also employees of the Company are not separately
compensated for serving on the Board of Directors. Directors who are not
employees of the Company receive $15,000 per year for their services as
directors. In addition, the Company reimburses them for the expenses incurred in
connection with attending meetings of the Board of Directors and its committees.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
     Section 102(b)(7) of the Delaware General Corporation Law ("DGCL") enables
a corporation to include in its certificate of incorporation a provision
eliminating or limiting the personal liability of members of its Board of
Directors to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director. Such a provision may not eliminate or limit the
liability of a director (1) for any breach of a director's duty of loyalty to
the corporation or its stockholders, (2) for acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of a law, (3) for
paying an unlawful dividend or approving an illegal stock repurchase (as
provided in Section 174 of the DGCL), or (4) for any transaction from which the
director derived an improper personal benefit.
 
     The Company has entered into indemnity agreements with each of its
executive officers and directors that provide for indemnification in certain
instances against liability and expenses incurred in connection with proceedings
brought by or in the right of the Company or by third parties by reason of a
person serving as an officer or director of the Company.
 
     The Company believes that these provisions and agreements will assist the
Company in attracting and retaining qualified individuals to serve as directors
and officers.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     None of the members of the Compensation Committee is or has been an
employee of the Company. No executive officer of the Company serves as a member
of the board of directors or compensation committee of any entity that has one
or more executive officers serving as a member of the Company's Board of
Directors or Compensation Committee. Messrs. Hightower, Staley, Albin, Hersh and
Vaughn, or their affiliates, have acquired capital stock of the Company. See
"Certain Transactions."

    on assumed rates of stock price appreciation of 0%, 5% and 10% compounded
    annually from March 31, 1995, as if such options had been granted on such
    date, through the expiration date.

  Employment Agreements
 
     The Company and Jack Hightower are parties to an Employment Agreement (the
"Employment Agreement") that provides for the employment of Mr. Hightower as
President, Chief Executive Officer and Chairman of the Board of the Company for
a two year period. The agreement provides for an annual salary of $160,000,
subject to any increases that may be approved by the Compensation Committee of
the Board of Directors from time to time during the term of the Employment
Agreement. Under the Employment Agreement, Mr. Hightower shall be entitled to
participate in any employee benefit programs which the
 
                                       40
<PAGE>   43
 
   
Company provides to its executive officers. As of the date hereof, the employee
benefit programs offered by the Company to its officers and employees include
group insurance coverage, participation in the Company's 401(k) Retirement Plan
and the 1996 Incentive Plan. Under the Employment Agreement, Mr. Hightower will
be entitled to receive up to one year's base salary if his employment is
terminated other than for cause (as defined therein) prior to the expiration of
his employment term. The agreement also provides that Mr. Hightower will not
compete with the Company for a certain period of time following any termination
of his employment for any reason.
    
 
     Each of the other executive officers of the Company is a party to a
confidentiality and noncompete agreement with the Company.
 
EMPLOYEE BENEFIT PLANS
 
     Initial Stock Option Plan. An option plan was adopted by the Company (the
"Initial Stock Option Plan"), in connection with the Conversion. The Initial
Stock Option Plan replaces the Option Plan adopted by the Partnership upon its
formation (the "Partnership Option Plan"). The terms of the Initial Stock Option
Plan and the options granted thereunder are substantially the same as the terms
of the Partnership Option Plan and the options granted thereunder (the
"Partnership Options"). All Partnership Options available under the Partnership
Plan were granted to officers and employees prior to the Conversion. Pursuant to
the Exchange Agreement, the Company was required to adopt the Initial Stock
Option Plan and issue options thereunder to each holder of the Partnership
Options, upon substantially the same terms as the Partnership Options held by
such holder. The Partnership and each of the holders of the Partnership Options
consented to the substitution of the Initial Stock Option Plan and the options
issued thereunder for the Partnership Option Plan and the Partnership Options.
 
     The Initial Option Plan is for the benefit of the officers and employees of
the General Partner and the Partnership who held partnership options. Options
granted under the Plan may be exercised to acquire up to an aggregate of
3,631,350 shares of Common Stock at an exercise price per share of $2.08. Any
option holder may elect to pay the exercise price for an option in cash, or by
delivery of the option holder's secured interest-bearing promissory term note
(payable to the Company in fifteen months), or by any combination of the
foregoing.
 
     There are four different series of options authorized under the plan, the
terms of which are substantially the same, except for the vesting requirements.
The Series A Options, which cover 2,410,728 option shares, vest ratably over
three years upon each anniversary date of March 31, if the holder remains
employed by the Company as of such date. If the holder's employment is
terminated prior to a vesting date either voluntarily by such holder or by
action of the Company for reasons other than for cause (as specified therein)
the Option may be exercised within three months after such termination (if
otherwise prior to the date of expiration of the Option), to purchase the number
of units then vested (with pro-rata vesting if in mid-year). One third of the
shares subject to the Series A Options (803,576 shares) are currently vested.
The Board of Directors of the Company has adopted a resolution, pursuant to the
terms of the Series B, C and D options granted under the plan, which declares
that the right to exercise the Series B Options, which cover 387,265 option
shares, will vest on March 31, 1997, the right to exercise the Series C Options,
which cover 406,390 shares, will vest on March 31, 1998 and the right to
exercise the Series D Options, which cover 426,967 shares, will vest on March
31, 1999.
 
   
     1996 Incentive Plan. The Board of Directors and the stockholders of the
Company approved the adoption of the Company's 1996 Incentive Plan (the "1996
Incentive Plan") as of October 1, 1996. The purpose of the 1996 Incentive Plan
is to reward selected officers and key employees of the Company and others who
have been or may be in a position to benefit the Company, compensate them for
making significant contributions to the success of the Company and provide them
with a proprietary interest in the growth and performance of the Company.
    
 
     Participants in the 1996 Incentive Plan are selected by the Board of
Directors or such committee of the Board as is designated by the Board to
administer the 1996 Incentive Plan (upon completion of this offering, the
Compensation Committee of the Board of Directors) from among those who hold
positions of responsibility with the Company and whose performance, in the
judgment of the Compensation Committee,
 
                                       41
<PAGE>   44
 
   
can have a significant effect on the success of the Company. An aggregate of
850,000 shares of Common Stock have been authorized and reserved for issuance
pursuant to the 1996 Incentive Plan. As of October 1, 1996, options have been
granted to participants under the 1996 Incentive Plan to purchase a total of
85,000 shares of Common Stock at an exercise price per share equal to the Price
to Public set forth on the cover page of this Prospectus. These options vest
ratably on each of the first through fourth anniversaries of the grant date.
    
 
     Subject to the provisions of the 1996 Incentive Plan, the Compensation
Committee will be authorized to determine the type or types of awards made to
each participant and the terms, conditions and limitations applicable to each
award. In addition, the Compensation Committee will have the exclusive power to
interpret the 1996 Incentive Plan and to adopt such rules and regulations as it
may deem necessary or appropriate in keeping with the objectives of the 1996
Incentive Plan.
 
   
     Pursuant to the 1996 Incentive Plan, participants will be eligible to
receive awards consisting of (i) stock options, (ii) stock appreciation rights,
(iii) stock, (iv) restricted stock, (v) cash or (vi) any combination of the
foregoing. Stock options may be either incentive stock options within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended, or
nonqualified stock options.

                              CERTAIN TRANSACTIONS
 
   
     On March 31, 1995, the Partnership was formed with an initial
capitalization of approximately $20.5 million by NGP and certain individuals,
including the following officers and directors of the Company: Jack D. Hightower
(President, Chief Executive Officer and Chairman of the Board), George G. Staley
(Executive Vice President, Exploration, and Director), Rodney L. Woodard (Vice
President, Engineering), Thomas H. Moore (Vice President, Business Development),
Dan P. Colwell (Vice President, Land), David R. Albin (Director), Kenneth A.
Hersh (Director) and William J. Vaughn, Jr. (prospective Director). On December
11, 1995, the Company sold partnership units equivalent to 3,423,194 shares and
1,711,597 shares of Common Stock to JEDI and First Union Corporation,
respectively, for $10 million and $5 million, respectively. In connection with
these transactions, the Company granted NGP, Jack Hightower, JEDI and First
Union Corporation certain registration rights. See "Description of Capital
Stock -- Registration Rights."
    
 
   
     The Company has entered into an administrative services contract with
Staley Operating Co. ("Staley Operating"), an affiliate of Mr. Staley. Pursuant
to the agreement, the Company provided certain administrative, accounting and
other office and technical services on behalf of Staley Operating, in its
capacity as the operator of certain producing oil and gas properties, in return
for which the Company received the amounts charged by Staley Operating for
providing such services under the applicable operating agreements for such
properties. The total amount of payments received by the Company under such
agreement was $241,563 in 1995 and $139,789 for the nine months ended September
30, 1996.
    
 
   
     Mr. Hightower and certain of his affiliates have a common ownership
interest in the Haley 1302 gas well located in Winkler County, Texas. The well
is operated by the Company and, in accordance with a standard industry operating
agreement, Mr. Hightower and certain of his affiliates make payments to the
Company of leasehold costs and lease operating and supervision charges. These
payments aggregated approximately $12,000 for the nine months ended December 31,
1995 and approximately $284,000 for the nine months ended September 30, 1996.
The Company does not consider the property to constitute a material portion of
its assets and believes that the terms of the operating agreement and
arrangements pertaining to the property are no less favorable to the Company
than could have been obtained from unaffiliated third parties.
    
 
   
     In April 1995, the Company purchased certain oil and gas properties from
Enertex, Inc., an affiliate of Mr. Hightower, and from Staley Gas Co. Inc.
("Staley"), an affiliate of George Staley. The purchase price for such
properties was approximately $1,065,000 for the Enertex properties and
approximately $77,000 for the Staley properties. The Company believes that the
terms of such property purchases were no less favorable to the Company than
could have been obtained from unaffiliated third parties.
    
 
   
     For advisory services in connection with the organization and initial
financing of the Company, the Company paid NGP $125,000. The Company is also a
party to separate financial advisory services contracts with ECT Securities
Corp. ("ECT") (an affiliate of JEDI) and NGP. In 1995, the Company made payments
to ECT and NGP of $200,000 and approximately $79,000, respectively, for fees and
expense reimbursements under these agreements. During 1996, ECT is entitled to
an annual fee of $100,000, payable quarterly in arrears, plus expense
reimbursements, and NGP is entitled to an annual fee of $85,000 payable
quarterly in arrears, plus expense reimbursements. Both agreements will
terminate as of the completion of this offering.
    
 
   
     In November 1995, the Company entered into master agreements for energy
price swaps with ECTRC and First Union National Bank of North Carolina,
affiliates of JEDI and First Union Corporation, respectively. Pursuant to the
terms of these agreements and as a result of losses attributable to natural gas
hedges, the Company paid $169,500 to each of ECTRC and First Union National Bank
of North Carolina. The Company believes that the terms of the agreement are no
less favorable to it than could have been obtained from unaffiliated third
parties.
    
 
   
     For the nine months ended September 30, 1996, sales to Enron Corp. (an
affiliate of JEDI), its subsidiaries and affiliates were approximately 52% of
the Company's oil and gas revenues. The Company believes that the terms of these
sales are no less favorable to it than could have been obtained from
unaffiliated third parties.

<PAGE>   46
 
   
     The Company's offices located at 500 West Texas, Suite 500, in Midland,
Texas are leased from Fasken Center Ltd., an affiliate of Mr. Hightower. The
lease is a noncancellable operating lease that terminates on December 31, 1998
and requires monthly rent payments of $9,219. The Company expects to amend the
lease in the fourth quarter of 1996 to obtain additional space. In addition, the
Company also regularly uses certain aircraft owned by Lone Star Jet, Inc., an
affiliate of Jack Hightower. The Company is billed by Lone Star Jet, Inc. for
any use of such aircraft by Company personnel. Approximately $4,000 was paid by
the Company for the use of such aircraft in 1995 and approximately $11,000 was
paid for the nine months ended September 30, 1996. The Company believes that the
terms of these agreements and arrangements with affiliates of Mr. Hightower are
no less favorable to the Company than could be obtained from unaffiliated third
parties.
    
 
     First Union Bank of North Carolina, an affiliate of First Union
Corporation, is a member of the bank group that lends to the Company under the
Credit Agreement. See "Use of Proceeds."
 
     Mr. Hightower is party to an Employment Agreement that provides for his
employment as President, Chief Executive Officer and Chairman of the Board of
the Company for a two year period. See "Management -- Executive Compensation."

32,050,013 shares of Common Stock will be issued and outstanding upon completion
of this offering (33,941,513 shares if the Underwriters exercise their
over-allotment option in full). As of September 30, 1996, the Company had
outstanding 19,550,013 shares of Common Stock held of record by 24 stockholders
and stock options for an aggregate of 3,631,350 shares.
    
 
COMMON STOCK
 
   
     The holders of Common Stock are entitled to one vote for each share held of
record on all matters submitted to the stockholders, and are entitled to
cumulate their votes for the election of directors. As a result of such
cumulative voting rights, any holder of at least 20% of the outstanding Common
Stock will be assured that such holder's nominee will be elected as a director
for so long as the Board of Directors of the Company consists of five members.
See "Risk Factors -- Control by Existing Stockholders." The Certificate of
Incorporation of the Company does not allow the stockholders to take action by
less than unanimous consent, but does permit the holders of 10% or more of the
Company's outstanding Common Stock to call a special meeting of the stockholders
not more frequently than once during each calendar year. Each share of Common
Stock is entitled to participate equally in dividends, if, as and when declared
by the Company's Board of Directors, and in the distribution of assets in the
event of liquidation, subject in all cases to any prior rights of outstanding
shares of Preferred Stock. The Company has never paid cash dividends on its
Common Stock. The shares of Common Stock have no preemptive or conversion
rights, redemption rights, or sinking fund provisions. The outstanding shares of
Common Stock are, and the shares of Common Stock offered hereby upon issuance
and sale will be, duly authorized, validly issued, fully paid, and
nonassessable.
    
 
PREFERRED STOCK
 
     As of September 30, 1996, the Company has no outstanding Preferred Stock.
The Company is authorized to issue 10,000,000 shares of Preferred Stock. The
Company's Board of Directors may establish, without stockholder approval, one or
more classes or series of Preferred Stock having the number of shares,
designations, relative voting rights, dividend rates, liquidation and other
rights, preferences, and limitations that the Board of Directors may designate.
The Company believes that this power to issue Preferred Stock will provide
flexibility in connection with possible corporate transactions. The issuance of
Preferred Stock, however, could adversely affect the voting power of holders of
Common Stock and restrict their rights to receive payments upon liquidation of
the Company. It could also have the effect of delaying, deferring or preventing
a change in control of the Company. The Company does not currently plan to issue
any shares of Preferred Stock.
 
DELAWARE LAW PROVISIONS
 
   
     The Company is a Delaware corporation and is subject to Section 203 of the
Delaware General Corporation Law. Generally, Section 203 prohibits the Company
from engaging in a "business combination" (as defined in Section 203) with an
"interested stockholder" (defined generally as a person owning 15% or more of
the Company's outstanding voting stock) for three years following the date that
person becomes an interested stockholder, unless (a) before that person became
an interested stockholder, the Company's Board of Directors approved the
transaction in which the interested stockholder became an interested stockholder
or approved the business combination; (b) upon completion of the transaction
that resulted in the interested stockholder's becoming an interested
stockholder, the interested stockholder owns at least 85% of the voting stock
outstanding at the time the transaction commenced (excluding stock held by
directors who are also officers of the Company and by employee stock plans that
do not provide employees with the right to determine confidentially whether
shares held subject to the plan will be tendered in a tender or exchange offer)
or (c) following the transaction in which that person became an interested
stockholder, the business combination is approved by the Company's Board of
Directors and authorized at a meeting of stockholders by
    
 
                                       47
<PAGE>   50
 
the affirmative vote of the holders of at least two-thirds of the outstanding
voting stock not owned by the interested stockholder.
 
     Under Section 203, these restrictions also do not apply to certain business
combinations proposed by an interested stockholder following the announcement or
notification of one of certain extraordinary transactions involving the Company
and a person who was not an interested stockholder during the previous three
years or who became an interested stockholder with the approval of a majority of
the Company's directors, if that extraordinary transaction is approved or not
opposed by a majority of the directors who were directors before any person
became an interested stockholder in the previous three years or who were
recommended for election or elected to succeed such directors by a majority of
such directors then in office.
 
REGISTRATION RIGHTS
 
     The Company has entered into the Amended and Restated Registration Rights
Agreement with Natural Gas Partners, L.P., Natural Gas Partners, II, L.P., Jack
Hightower, JEDI, First Union Corporation and Selma International Investment
Limited (the "Shareholder Parties"). See "Management -- Certain Transactions."
Pursuant to the Amended and Restated Registration Rights Agreement, on three
separate occasions, commencing on the 180th day following the date of the
Company's initial registration statement under the securities laws, Shareholder
Parties owning at least 35% of the outstanding shares then subject to such
agreement may require the Company to register shares held by them under
applicable securities laws, provided that the shares to be registered have an
estimated aggregate offering price to the public of at least $3,000,000. The
Amended and Restated Registration Rights Agreement also provides that the
Shareholder Parties have "piggyback" registration rights pursuant to which such
persons may include shares of Common Stock held by them in certain registrations
initiated by the Company or by any other holder of the Company's Common Stock;
provided that, in an underwritten registered offering, if the managing
underwriters determine that the number of shares requested to be included in the
registration exceeds the number that the underwriters believe can be sold, the
Company will be given first priority and the persons requesting piggyback
registration under the Amended and Restated Registration Rights Agreement will
be allowed to include shares pro rata based on the number of shares each such
person requested to be included.
 
     The Amended and Restated Registration Rights Agreement provides for
customary indemnities by the Company in favor of persons including shares in a
registration pursuant to the Amended and Restated Registration Rights Agreement,
and by such persons in favor of the Company, with respect to information to be
included in the relevant registration statement. These registration rights have
been waived in connection with this offering and for 180 days after the date of
this Prospectus.
 
TRANSFER AGENT AND REGISTRAR
 
   
     The Transfer Agent and Registrar for the Common Stock is First Union
National Bank of North Carolina.
    
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon completion of this offering, the Company will have 32,050,013 shares
of Common Stock outstanding (33,941,513 shares if the Underwriters exercise
their over-allotment option in full). Of these shares, the 12,500,000 shares of
Common Stock sold in this offering will be freely transferable without
restriction under the Securities Act unless they are held by the Company's
affiliates, as that term is used in Rule 144 under the Securities Act. The
Company issued the remaining 19,550,013 shares of Common Stock in reliance on
exemptions from the registration requirements of the Securities Act, and those
shares are "restricted" securities under Rule 144. Those shares may not be sold
publicly unless they are registered under the Securities Act, sold in compliance
with Rule 144, or sold in a transaction that is exempt from registration. The
Company believes that the earliest date on which the 19,550,013 shares of its
Common Stock currently outstanding will be eligible for sale under Rule 144 is
October 1, 1998. Therefore, no shares will be eligible for immediate sale in the
public market without restriction under Rule 144(k), and no shares will be
eligible for immediate sale under the manner-of-sale, volume and other
limitations of Rule 144. Beginning October 1,
    
 
                                       48
<PAGE>   51
 
1998, all of the shares of Common Stock currently outstanding will become
eligible for sale under Rule 144, based on current Commission rules and subject
to compliance with the manner-of-sale, volume and other requirements of Rule
144. Beginning October 1, 1999, all of those shares of Common Stock will become
eligible for sale under Rule 144(k) if they are not held by affiliates of the
Company.
 
   
     In general, under Rule 144 a person (or persons whose sales are
aggregated), including an affiliate, who has beneficially owned shares for at
least two years is entitled to sell in broker transactions, within any three-
month period commencing 90 days after this offering, a number of shares that
does not exceed the greater of (i) 1% of the then outstanding Common Stock
(approximately 320,500 shares immediately after this offering) or (ii) the
average weekly trading volume in the Common Stock during the four calendar weeks
preceding the sale, subject to the filing of a Form 144 with respect to the sale
and other limitations. In addition, a person who was not an affiliate of the
Company during the three months preceding a sale and who has beneficially owned
the shares proposed to be sold for at least three years is entitled to sell the
shares under Rule 144(k) without regard to the manner-of-sale, volume and other
limitations of Rule 144. The Commission has proposed to shorten the holding
periods under Rule 144 for restricted securities. The Commission has indicated
that, if adopted, the proposed amendment would apply to all outstanding
restricted securities. All shares of Common Stock, other than those offered
hereby, are subject to lock-up agreements with the Underwriters for 180 days
after the date of this Prospectus. See "Underwriting."
    
 
     The holders of approximately 13,225,429 shares of Common Stock and their
permitted transferees are entitled to demand registration of those shares under
the Securities Act beginning 180 days after the date of this Prospectus. See
"Description of Capital Stock -- Registration Rights."
 
     The Company intends to file a registration statement under the Securities
Act to register Common Stock to be issued pursuant to the exercise of options,
including options under the Incentive Plan. Taking into account the effect of
the lock-up agreement with the holders of options, approximately
shares issuable upon exercise of vested options will be eligible for sale in the
public market beginning 180 days after commencement of this offering, subject,
in the case of sales by affiliates, to the manner-of-sale, volume and other
limitations requirements of Rule 144.
 
     Prior to this offering, there has been no public market for the securities
of the Company. No prediction can be made of the effect, if any, that the sale
or availability for sale of shares of additional Common Stock will have on the
market price of the Common Stock. Nevertheless, sales of substantial numbers of
shares by existing stockholders or by stockholders purchasing in this offering
could have a negative effect on the market price of the Common Stock.

     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters will be obligated to purchase all the shares of Common Stock
offered hereby (other than those shares covered by the over-allotment option
described below) if any are purchased. The Underwriting Agreement provides that,
in the event of a default by an Underwriter, in certain circumstances the
purchase commitments of nondefaulting Underwriters may be increased or the
Underwriting Agreement may be terminated.
 
   
     The Company has granted to the Underwriters an option, expiring at the
close of business on the 30th day after the date of this Prospectus, to purchase
up to 1,891,500 additional shares of Common Stock at the initial public offering
price less the underwriting discounts and commissions, all as set forth on the
cover page of this Prospectus. Such option may be exercised only to cover
over-allotments in the sale of the shares of Common Stock. To the extent such
option is exercised, each Underwriter will become obligated, subject to certain
conditions, to purchase approximately the same percentage of such additional
shares of Common Stock as it was obligated to purchase pursuant to the
Underwriting Agreement.
    
 
     The Company has been advised by the Representatives that the Underwriters
propose to offer the shares of Common Stock to the public initially at the
public offering price set forth on the cover page of this Prospectus and,
through the Representatives, to certain dealers at such price less a concession
of $          per share, and the Underwriters and such dealers may allow a
discount of $          per share on sales to certain other dealers. After the
initial public offering, the public offering price and concession and discount
to dealers may be changed by the Representatives.
 
     The Representatives have informed the Company that they do not expect
discretionary sales by the Underwriters to exceed five percent of the shares
being offered hereby.
 
     The Company intends to use more than 10% of the net proceeds from the sale
of the shares offered by the Company to repay indebtedness owed by it to Morgan
Guaranty Trust Company of New York, an affiliate of one of the underwriters,
J.P. Morgan Securities Inc. Accordingly, this offering is being made in
compliance with the requirements of Rule 2720(c) of the Conduct Rules of the
National Association of Securities

Dealers, Inc. This rule provides generally that if more than 10% of the net
proceeds from the sale of stock, not including underwriting compensation, is
paid to the underwriters of such stock or their affiliates, the initial public
offering price of the stock may not be higher than that recommended by a
"qualified independent underwriter" meeting certain standards. CS First Boston
Corporation is assuming the responsibilities of acting as the qualified
independent underwriter in pricing this offering and conducting due diligence.
The initial public offering price of the Shares set forth on the cover page of
this Prospectus is no higher than the price recommended by CS First Boston
Corporation.
    
 
     The Company, its officers, directors, stockholders and optionholders have
agreed that they will not offer, sell, contract to sell, announce an intention
to sell, pledge or otherwise dispose of, directly or indirectly, or file with
the Commission a Registration Statement under the Securities Act, relating to,
any additional shares of the Company's Common Stock or securities convertible
into or exchangeable or exercisable for any shares of the Company's Common Stock
without the prior written consent of CS First Boston Corporation for a period of
180 days after the date of this Prospectus, except issuances pursuant to the
exercise of employee stock options outstanding on the date hereof. See "Shares
Eligible for Future Sale."
 
     Prior to this offering, there has been no public market for the Common
Stock. The initial public offering price for the shares of Common Stock was
negotiated among the Company and the Underwriters. Among the factors considered
in determining the initial public offering price, in addition to prevailing
market conditions, are the history of, and prospects for, the industry in which
the Company operates, the earnings of the Company and comparable companies in
recent periods, management expertise and the Company's business potential and
earnings prospects.
 
     The Company and the Selling Stockholder have agreed to indemnify the
Underwriters against certain liabilities, including civil liabilities under the
Securities Act, or contribute to payments which the Underwriters may be required
to make in respect thereof.
 
   
     Application has been made to list the shares of Common Stock on the
                         . In connection with the listing of the Common Stock on
the                          , the Underwriters will undertake to sell round
lots of 100 shares or more to a minimum of beneficial owners.

     "Present Value of Future Net Revenues" or "PV-10" means the pretax present
value of estimated future revenues to be generated from the production of proved
reserves calculated in accordance with Commission guidelines, net of estimated
production and future development costs, using prices and costs as of the date
of estimation without future escalation, without giving effect to non-property
related expenses such as general and administrative expenses, debt service and
depreciation, depletion and amortization, and discounted using an annual
discount rate of 10%.
 
     "Project" means a proposal to add a producing completion of oil or gas. A
proposal may vary in range from work authorized to be performed to proposals
that are founded in geologic and engineering principles yet require further
research before funds are authorized.
 
     "Proved developed reserves" means reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery will be included as "proved developed
reserves" only after testing by a pilot project or after the operation of an
installed program has confirmed through production response that increased
recovery will be achieved.
 
     "Proved reserves" means the estimated quantities of crude oil, natural gas,
and natural gas liquids which geological and engineering data demonstrate with
reasonable certainty to be recoverable in future years from known reservoirs
under existing economic and operating conditions, i.e., prices and costs as of
the date the estimate is made. Prices include consideration of changes in
existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.
 
          i. Reservoirs are considered proved if economic producibility is
     supported by either actual production or conclusive formation test. The
     area of a reservoir considered proved includes (A) that portion delineated
     by drilling and defined by gas-oil and/or oil-water contacts, if any; and
     (B) the immediately adjoining portions not yet drilled, but which can be
     reasonably judged as economically productive on the basis of available
     geological and engineering data. In the absence of information on fluid
     contacts, the lowest known structural occurrence of hydrocarbons controls
     the lower proved limit of the reservoir.
 
          ii. Reserves which can be produced economically through application of
     improved recovery techniques (such as fluid injection) are included in the
     "proved" classification when successful testing by a pilot project, or the
     operation of an installed program in the reservoir, provides support for
     the engineering analysis on which the project or program was based.
 
          iii. Estimates of proved reserves do not include the following: (A)
     oil that may become available from known reservoirs but is classified
     separately as "indicated additional reserves"; (B) crude oil, natural gas,
     and natural gas liquids, the recovery of which is subject to reasonable
     doubt because of uncertainty as to geology, reservoir characteristics, or
     economic factors; (C) crude oil, natural gas, and natural gas liquids that
     may occur in undrilled prospects; and (D) crude oil, natural gas, and
     natural gas liquids that may be recovered from oil shales, coal, gilsonite
     and other such sources.
 
     "Proved undeveloped reserves" means reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage shall be limited to those drilling units offsetting productive units
that are reasonably certain of production when drilled. Proved reserves for
other undrilled units can be claimed only where it can be demonstrated with
certainty that there is continuity of production from the existing productive
formation. Under no circumstances should estimates for proved undeveloped
reserves be attributable to any acreage for which an application of fluid
injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual tests in the area and in the
same reservoir.
 
     "Recompletion" means the completion for production of an existing well bore
in another formation from that in which the well has been previously completed.
 
     "Reserves" means proved reserves.
 
                                       55
<PAGE>   58
 
     "Royalty" means an interest in an oil and gas lease that gives the owner of
the interest the right to receive a portion of the production from the leased
acreage (or of the proceeds of the sale thereof), but generally does not require
the owner to pay any portion of the costs of drilling or operating the wells on
the leased acreage. Royalties may be either landowner's royalties, which are
reserved by the owner of the leased acreage at the time the lease is granted, or
overriding royalties, which are usually reserved by an owner of the leasehold in
connection with a transfer to a subsequent owner.
 
   
     "Sidetrack drilling" means an operation involving the use of a portion of
an existing well to drill a second hole, resulting in a well that is partly old
and partly new.
    
 
     "Spud" means to start drilling a new well (or restart).
 
     "3-D seismic" means seismic data that are acquired and processed to yield a
three-dimensional picture of the subsurface.
 
   
     "Spudded" means the first boring of the hole in the drilling of a well.
    
 
   
     "Step-out well" means a well drilled adjacent to a proven well but located
in an unproven area; a well drilled as a "step-out" from proven territory in an
effort to ascertain the extent and boundaries of a producing formation.
    
 
     "Tcf" means trillion cubic feet of natural gas.
 
   
     "Tertiary recovery" means enhanced recovery methods for the production of
oil or gas. Enhanced recovery of crude oil requires a means for displacing oil
from the reservoir rock, modifying the properties of the fluids in the reservoir
and/or the reservoir rock to cause movement of oil in an efficient manner, and
providing the energy and drive mechanism to force its flow to a production well.
The Company injects chemicals or energy as required for displacement and for the
control of flow rate and flow pattern in the reservoir, and a fluid drive is
provided to force the oil toward a production well.
    
 
     "Waterflood" means the injection of water into a reservoir to fill pores
vacated by produced fluids, thus maintaining reservoir pressure and assisting
production.
 
     "Working interest" means an interest in an oil and gas lease that gives the
owner of the interest the right to drill for and produce oil and gas on the
leased acreage and requires the owner to pay a share of the costs of drilling
and production operations. The share of production to which a working interest
owner is entitled will always be smaller than the share of costs that the
working interest owner is required to bear, with the balance of the production
accruing to the owners of royalties. For example, the owner of a 100% working
interest in a lease burdened only by a landowner's royalty of 12.5% would be
required to pay 100% of the costs of a well but would be entitled to retain
87.5% of the production.
 
     "Workover" means operations on a producing well to restore or increase
production.

                    PRO FORMA CONDENSED FINANCIAL STATEMENTS
 
   
     The Unaudited Pro Forma Condensed Financial Statements of the Company have
been prepared to give effect to the 1995 Acquisition and the 1996 Acquisition,
the Conversion, and this offering and the application of the estimated net
proceeds therefrom as if such transactions (to the extent not already reflected)
had taken place on September 30, 1996 for purposes of the Pro Forma Condensed
Balance Sheet and as if the transactions had taken place on January 1, 1995 for
purposes of the Pro Forma Condensed Statements of Operations. The Pro Forma
Condensed Financial Statements of the Company are not necessarily indicative of
the results for the periods presented had the 1995 Acquisition and the 1996
Acquisition, the Conversion, and this offering and the application of the
estimated net proceeds therefrom taken place on January 1, 1995. In addition,
future results may vary significantly from the results reflected in the
accompanying Pro Forma Condensed Financial Statements because of normal
production declines, changes in product prices, and the success of future
exploration and development activities, among other factors. This information
should be read in conjunction with the Consolidated Financial Statements of
Titan Exploration, Inc., and the Statements of Revenues and Direct Operating
Expenses with respect to the properties acquired in the 1995 Acquisition and the
1996 Acquisition, all included elsewhere herein.

     (i) To adjust interest expense to reflect the partial repayment of

(3) INCOME TAXES
 
   
     The Company accounts for income taxes pursuant to the provisions of SFAS
109. At September 30, 1996, the pro forma book basis of the Company's assets and
liabilities exceeded the pro forma tax basis by approximately $8,818,000, giving
rise to an estimated deferred tax liability of approximately $2,998,000. The
temporary differences are primarily related to the differences in book and tax
basis of oil and gas properties due to the expensing of intangible development
costs for tax purposes and other income tax differences arising from the tax
treatment of oil and gas producing activities.
    
 
(4) NET INCOME (LOSS) PER SHARE
 
   
     Net income (loss) per share is calculated based on the pro forma weighted
average shares outstanding during the respective periods. Weighted average
shares reflect the pro forma issuance of 5,134,791 shares of Common Stock on
December 11, 1995, the pro forma issuance of 13,692,776 shares of Common Stock
to the original holders prior to January 1, 1995 and the issuance on September
27, 1996 of 722,446 shares for total consideration of $5,000,000. In addition,
the issuance of 12,500,000 shares in this offering is assumed to have taken
place on January 1, 1995 and assumes that the underwriters' overallotment option

(5) SUPPLEMENTAL OIL AND GAS RESERVE INFORMATION (UNAUDITED)
 
   
     The estimates of proved oil and gas reserves, which are located in the
United States, were prepared by the Company as of December 31, 1993, 1994 and
1995. Reserves were estimated in accordance with guidelines established by the
Securities and Exchange Commission and FASB which require that reserve estimates
be prepared under existing economic and operating conditions with no provision
for price and cost escalations except by contractual arrangements. The Company
has presented the pro forma reserve estimates utilizing an oil price of $23.37
per Bbl and a gas price of $1.39 per Mcf as of September 30, 1996. The pro forma
information assumes that both the 1995 Acquisition and the 1996 Acquisition took
place on January 1, 1995.
    
 
     Oil and gas reserve quantity estimates are subject to numerous
uncertainties inherent in the estimation of quantities of proved reserves and in
the projection of future rates of production and the timing of development
expenditures. The accuracy of such estimates is a function of the quality of
available data and of engineering and geological interpretation and judgment.
Results of subsequent drilling, testing and production may cause either upward
or downward revision of previous estimates. Further, the volumes considered to
be commercially recoverable fluctuate with changes in prices and operating
costs. The Company emphasizes that reserve estimates are inherently imprecise
and that estimates of new discoveries are more imprecise than those of currently
producing oil and gas properties. Accordingly, these estimates are expected to
change as additional information becomes available in the future.

  Standardized Measure of Discounted Future Net Cash Flows of Proved Oil and Gas
Reserves
 
     The standardized measure of discounted future net cash flows is computed by
applying year-end prices of oil and gas (with consideration of price changes
only to the extent provided by contractual arrangements) to the estimated future
production of proved oil and gas reserves less estimated future expenditures
(based on period-end costs) to be incurred in developing and producing the
proved reserves, less estimated future income tax expenses (based on period-end
statutory tax rates, with consideration of future tax rates already legislated)
to be incurred on pretax net cash flows less tax basis of the properties and
available credits, and assuming continuation of existing economic conditions.
The estimated future net cash flows are then discounted using a rate of 10% per
year to reflect the estimated timing of the future cash flows.
 
     Discounted future cash flow estimates like those shown below are not
intended to represent estimates of the fair value of oil and gas properties.
Estimates of fair value should also consider probable reserves, anticipated
future oil and gas prices, interest rates, changes in development and production
costs and risks

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Titan Exploration, Inc.
 
     We have audited the accompanying consolidated balance sheet of Titan
Exploration, Inc. and subsidiaries (the Company) as of December 31, 1995, and
the related consolidated statement of operations, stockholders' equity, and cash
flows for the period from March 31, 1995 (date of inception) through December
31, 1995. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Titan Exploration, Inc. and subsidiaries as of December 31, 1995, and the
results of its operations and its cash flows for the period from March 31, 1995
(date of inception) through December 31, 1995, in conformity with generally
accepted accounting principles.

The Board of Directors and Shareholders
    
   
Titan Exploration, Inc.
    
 
   
     We have reviewed the consolidated balance sheet of Titan Exploration, Inc.
and subsidiaries as of September 30, 1996, and the related consolidated
statements of operations and cash flows for the period March 31, 1995 (date of
inception) through September 30, 1995 and the nine-month period ended September
30, 1996. These financial statements are the responsibility of the Company's
management.
    
 
   
     We conducted our reviews in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical review
procedures to financial data and making inquiries 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 consolidated financial statements referred to above for
them to be in conformity with generally accepted accounting principles.

(1) ORGANIZATION AND NATURE OF OPERATIONS
 
     Titan Exploration, Inc. (the "Company"), a Delaware corporation, was
organized on September 27, 1996 and began operations on September 30, 1996 with
the combination, pursuant to the terms of an Exchange Agreement and Plan of
Reorganization (the "Exchange Agreement"), of Titan Resources I, Inc. (the
"General Partner"), a Texas corporation, and Titan Resources, L.P. (the
"Partnership"). Under the exchange agreement, the limited partners of the
Partnership transferred all of their limited partnership interests to the
Company in exchange for 19,318,199 shares of common stock, and the General
Partner transferred all of the issued and outstanding stock of that corporation
to the Company in exchange for an aggregate of 231,814 shares of common stock.
These transactions are referred to as the "Conversion."
 
     The Partnership and the General Partner were under common control due to
the General Partner's sole general partnership interest and control over the
Partnership and due to the commonality of ownership between the General Partner
and the Partnership. Consequently, the accompanying consolidated financial
statements have given effect to the Conversion as if it were a pooling of
interests. Revenues and costs arising from transactions between the two
predecessor entities (the General Partner and the Partnership) have been
eliminated. The following table sets forth revenues and net income with respect
to the two predecessor entities (in thousands):

     The Company is an independent energy company engaged in the exploration,
development and acquisition of oil and gas properties. Since its inception in
March 1995, the Company has experienced significant growth, primarily through
the acquisition of oil and gas properties and the exploitation of these
properties in the Permian Basin region of west Texas and southeastern New
Mexico.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its subsidiaries, each of which is wholly owned, since their formation (See
Note 1). All material intercompany accounts and transactions have been
eliminated in the consolidation.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
        (THE INFORMATION AND AMOUNTS FOR INTERIM PERIODS ARE UNAUDITED)
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
  Use of Estimates
 
     Preparation of the accompanying consolidated 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 consolidated financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Cash and Cash Equivalents
 
     For purposes of the statements of cash flows, the Company considers all
demand deposits, money market accounts and certificates of deposit purchased
with an original maturity of three months or less to be cash equivalents.
 
  Oil and Gas Properties
 
     The Company utilizes the successful efforts method of accounting for its
oil and gas properties. Under this method of accounting, all costs associated
with productive wells and nonproductive development wells are capitalized while
nonproductive exploration costs are expensed.
 
     Costs of significant nonproducing properties, wells in the process of being
drilled and development projects are excluded from depletion until such time as
the related project is developed and proved reserves are established or
impairment is determined. The Company capitalizes interest on expenditures for
significant development projects until such time as significant operations
commence.
 
     Capitalized costs of individual properties abandoned or retired are charged
to accumulated depletion, depreciation and amortization. Sales proceeds from
sales of individual properties are credited to property costs. No gain or loss
is recognized until the entire amortization base is sold or abandoned.
 
     Other property and equipment are recorded at cost. Major renewals and
betterments are capitalized while the costs of repairs and maintenance are
charged to operating expenses in the period incurred. With respect to
dispositions of assets other than oil and gas properties, the cost of assets
retired or otherwise disposed of, and the applicable accumulated depreciation
are removed from the accounts, and the resulting gains or losses, if any, are
reflected in operations.
 
  Depletion, Depreciation and Amortization
 
     Provision for depletion of oil and gas properties is calculated using the
unit-of-production method on the basis of an aggregation of properties with a
common geologic structural feature or stratigraphic condition, typically a field
or reservoir. Other property and equipment is depreciated using the
straight-line method over the estimated useful lives of the assets. Organization
costs are amortized over five years, while loan costs are amortized over the
life of the related loan.
 
  Impairment of Long-Lived Assets
 
     The Company follows the provisions of Statement of Financial Accounting
Standards No. 121 -- Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of ("FAS 121"). Consequently, the Company
reviews its long-lived assets to be held and used, including oil and gas
properties accounted for under the successful efforts method of accounting,
whenever events or circumstances indicate that the carrying value of those
assets may not be recoverable. An impairment loss is indicated if the sum of the
expected future cash flows is less than the carrying amount of the assets. No

impairment was determined to exist during the period March 31, 1995 (date of
inception) through December 31, 1995 or during the nine months ended September
30, 1996.
    
 
     The Company accounts for long-lived assets to be disposed of at the lower
of their carrying amount or fair value less cost to sell once management has
committed to a plan to dispose of the assets.
 
   
  Net Income (Loss) per Share
    
 
   
     Net income (loss) per share is calculated based on the weighted average
number of shares and share equivalents, if dilutive, outstanding during the
period.
    
 
  Income Taxes
 
     The Company follows the provisions of Financial Accounting Standards No.
109, "Accounting for Income Taxes" ("FAS 109"). Under the asset and liability
method of FAS 109, deferred tax assets and liabilities are recognized for the
future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases. Deferred tax assets and liabilities are measured using
enacted tax rates expected to apply to taxable income in the years in which
those temporary differences are expected to be recovered or settled. Under FAS
109, the effect on deferred tax assets and liabilities of a change in tax rate
is recognized in income in the period that includes the enactment date.
 
   
     The Company has recorded the tax effect of the differences between the book
and tax basis of it assets and liabilities as a deferred tax liability and a
corresponding charge to deferred income tax expense. At September 30, 1996, the
excess of book basis over tax basis of assets and liabilities is $8,818,000.
    
 
  Environmental
 
     The Company is subject to extensive federal, state and local environmental
laws and regulations. These laws, which are constantly changing, regulate the
discharge of materials into the environment and may require the Company to
remove or mitigate the environmental effects of the disposal or release of
petroleum or chemical substances at various sites. Environmental expenditures
are expensed or capitalized depending on their future economic benefit.
Expenditures that relate to an existing condition caused by past operations and
that have no future economic benefits are expensed. Liabilities for expenditures
of a noncapital nature are recorded when environmental assessment and/or
remediation is probable, and the costs can be reasonably estimated.
 
  Revenue Recognition
 
     The Company uses the sales method of accounting for crude oil revenues.
Under this method, revenues are recognized based on actual volumes of oil sold
to purchasers.
 
   
     The Company uses the entitlements method of accounting for natural gas
revenues. Under this method, revenues are recognized based on the Company's
proportionate share of actual sales of natural gas. Natural gas revenues would
not have been significantly altered in any period had the sales method of
recognizing natural gas revenues been utilized.
    
 
  Commodity Hedging
 
     The Company periodically enters into commodity derivative contracts (swaps)
in order to hedge the effect of price changes on commodities the Company
produces and sells. Gains and losses on contracts that

are designed to hedge commodities are included in income recognized from the
sale of those commodities. Gains and losses on derivative contracts which do not
qualify as hedges are recognized in each period based on the market value of the
related instrument.
 
  Interest Rate Swap Agreements
 
     The Company enters into interest rate swap agreements to effectively
convert a portion of its floating-rate borrowings into fixed rate obligations.
The interest rate differential to be received or paid is recognized over the
lives of the agreements as an adjustment to interest expense.
 
  Interim Consolidated Financial Statements
 
   
     The interim consolidated financial information as of September 30, 1996 and
for the periods ended September 30, 1995 and 1996, is unaudited. However, in the
opinion of management, these interim consolidated financial statements include
all the necessary adjustments to fairly present the results of the interim
periods, and all such adjustments are of a normal recurring nature. The interim
consolidated financial statements should be read in conjunction with the audited
financial statements for the period March 31, 1995 (date of inception) through
December 31, 1995.
    
 
(3) DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amount of cash, short-term investments, accounts receivable,
accounts payable, and accrued liabilities approximates fair value because of the
short maturity of these instruments.
 
     The carrying amount of long-term debt approximates fair value because the
Company's current borrowing rate does not materially differ from market rates
for similar bank borrowings.
 
   
     The fair market values of commodity derivative instruments are estimated
based upon the current market price of the respective commodities at the date of
valuation. It represents the amount which the Company would be required to pay
or able to receive based upon the differential between a fixed and a variable
commodity price as specified in the hedge contracts. At December 31, 1995 and
September 30, 1996, the Company would be required to pay approximately $606,000
and $652,000, respectively, to terminate the existing contracts.
    
 
   
     The fair values of interest rate swap agreements are obtained from bank
quotes. This value represents the estimated amount the Company would pay to
terminate the agreement, taking into consideration current interest rates. The
Company estimates that, at December 31, 1995, the Company would be required to
pay approximately $17,000 to terminate the existing interest rate swap
agreement. At September 30, 1996, Titan would be entitled to receive
approximately $3,900.
    
 
(4) LONG-TERM DEBT
 
     Long-term debt consists of the following at December 31, 1995 (in
thousands):

     On December 11, 1995, the Company entered into a credit agreement with
Texas Commerce Bank. The note provides for a two-year revolving line of credit
of $100,000,000 with an initial borrowing base of $35,000,000. The note converts
to a five-year term loan requiring twenty quarterly principal payments

(4) LONG-TERM DEBT (CONTINUED)
beginning January 1, 1998. The borrowing base is subject to redetermination
every six months with the next redetermination date being September 1, 1996. The
note is secured by substantially all of the Company's oil and gas properties.
Commitment fees are due quarterly and range from .300% to .375% per annum on the
difference between the borrowing base amount and the average daily amount
outstanding.
 
   
     The unpaid principal balance on the note bears interest at the Company's
option based on (i) the higher of (a) the prime rate of Texas Commerce Bank, or
(b) one-half of one percent plus the Federal Funds rate, or (ii) a Eurodollar
rate (based upon a floating rate for a designated maturity of ninety days
adjusted for a Eurodollar margin percentage as defined in the credit agreement).
The interest rate in effect at December 31, 1995 was the Eurodollar rate of
7.0625%. The interest rate in effect at September 30, 1996 was 6.75%.
    
 
     The credit agreement contains various restrictive covenants and compliance
requirements, which include (1) limiting the incurrence of additional
indebtedness, (2) limiting any mergers or consolidations with any party not
owned or controlled more than 50% by certain limited partners, on a consolidated
basis, and (3) prohibition of any return of capital payments or distributions to
any of its partners other than for taxes due as a result of their partnership
interest.
 
     The Company is a party to an interest rate swap agreement entered into on
December 21, 1995. The effect of this agreement is to provide the Company with a
fixed interest rate of 6.72% on $10,000,000 of its revolving line of credit
through December 23, 1996.

     On July 15, 1996, the Company borrowed an additional $8 million under its
line of credit in order to fund the required escrow payment on a potential
acquisition of certain oil and gas properties. (See Note 12).
 
(5) ACQUISITION OF OIL AND GAS PROPERTIES
 
     On December 11, 1995, the Company completed the acquisition of certain oil
and gas properties from a large independent oil and gas company (the "1995
Acquisition"). The Company funded the acquisition from the bank credit agreement
described in Note 4. The total consideration paid for the properties was
$39,881,094. The acquisition of these oil and gas properties, accounted for
using the purchase method, resulted in the following noncash investing
activities:

(7) DERIVATIVE FINANCIAL INSTRUMENTS
 
     The Company has only limited involvement with derivative financial
instruments and does not use them for trading purposes. They are used to manage
well-defined interest rate and commodity price risks. The Company is exposed to
credit losses in the event of nonperformance by the counterparties to its
interest rate swap agreements and its commodity hedges. The Company anticipates,
however, that such counterparties will be able to fully satisfy their
obligations under the contracts. The Company does not obtain collateral or other
security to support financial instruments subject to credit risk but monitors
the credit standing of the counterparties.
 
  Commodity Hedges
 
     The Company utilizes various swap contracts to hedge the effect of price
changes on future oil and gas production. The following table sets forth the
future volumes hedged by year and the weighted average price to be received
based upon the fixed price of the individual swap contracts at December 31,
1995:

     Under two separate natural gas swap agreements with a limited partner and
an affiliate of a limited partner, the Company receives the fixed price set
forth above. The Company pays a floating price determined as the NYMEX price,
reduced by 53% of the difference between the NYMEX price and the fixed price
received.
 
     The Company relies upon the correlation that generally exists between the
NYMEX gas futures price and the cash prices realizable to effectively hedge its
production. However, with the lack of recent correlation

between the NYMEX gas futures price and the cash prices realizable in gas
markets outside the Northeastern United States, the Company recognized in
December 1995 an approximate $147,000 loss related to an uncorrelated position
for early 1996 gas production.
 
   
     In April 1996, the Company entered into a natural gas swap agreement that
hedges a portion of the basis differential between the NYMEX price paid under
the contracts described above and actual cash prices received at local delivery
points. Under this contract covering 1,760,000 MMBtus of natural gas, the
Company pays a price equal to a Permian Basin index price and receives a price
based on the NYMEX price minus $.325 per MMBtu.
    
 
  Interest Rate Swap Agreements
 
   
     These instruments are used to reduce the potential impact of increases in
interest rates on floating-rate long-term debt. At December 31, 1995 and
September 30, 1996, the Company was a party to one interest rate swap agreement.
(See Note 4).

(9) COMPANY OPTION PLANS
 
   
     During 1995, the Titan Resources, L.P. established a unit option plan (the
"Plan") for certain officers and key employees of the Partnership and the
General Partner. The Plan provided for the issuance of 5,460,000 options in four
separate series with an initial exercise price of $1 which was to be increased
10% per annum from the initial plan adoption date of March 31, 1995. Option A
series, covering 3,624,706 units, was to vest at a rate of one-third of the
options at each of the dates of March 31, 1996, 1997 and 1998. Option B, C, and
D series were to vest on the dates that the Board determines that the current
value of partnership units had increased by a factor of 3, 4, and 5,
respectively or on the date that such per unit amounts of cash or other assets
have been or are authorized to be distributed to the Partners. Option B, C, and
D series cover 582,282, 611,037, and 641,975 units, respectively. As of December
31, 1995, 5,093,616 unit options had been awarded and none were vested or
exercised.
    
 
     Based on the price of equity interests sold at December 11, 1995, the
Company recorded deferred compensation for the expected value of the options,
amortized over the period from March 31, 1995 through March 31, 1998.
 
     On September 30, 1996, upon the consolidation of Titan Resources, L.P., the
Plan was replaced by a new stock option plan the ("Stock Plan"). The Stock Plan
provides for the issuance of 3,631,350 options to acquire common stock of the
Company, in four separate series with a fixed exercise price of $2.08. Option A
series, covering 2,410,728 shares of common stock, was to vest at a rate of
one-third of the options at each of the dates of March 31, 1996, 1997 and 1998.
Option B, C, and D series cover 387,265, 406,390, and 426,967 shares of common
stock, respectively and vest over a period through March 31, 1999. Deferred
compensation will be recorded based on the value of the Company's common stock
on September 30, 1996, and will be amortized to expense through March 31, 1999.

     In connection with the foregoing, the Company entered into a new credit
agreement (the "Credit Agreement") with Chase Securities, Inc., an affiliate of
the Company's current lender, which establishes a four year revolving credit
facility, up to the maximum amount of $250 million, subject to a borrowing base
to be determined semiannually by the lenders based on certain proved oil and gas
reserves and other assets of the Company. Proceeds of the credit facility will
be utilized to fund the 1996 Acquisition, development of oil and gas reserves,
and for general corporate requirements.
 
   
     The initial borrowing base is $165 million with the next redetermination
date scheduled for April 1, 1997. The credit agreement, which is secured by the
Company's proved oil and gas reserves, is subject to mandatory prepayments. To
the extent that the borrowing base is less than the aggregate principal amount
of all outstanding loans and letters of credit under the Credit Agreement, such
deficiency must be cured by the Company ratably within 180 days, by either
prepaying a portion of the outstanding amounts or pledging additional
collateral.
    
 
     At the Company's option, borrowings under the Credit Agreement bear
interest at either (i) the "Alternate Base Rate" (i.e. the higher of the agent's
prime commercial lending rate, or the federal funds rate

(14) SUPPLEMENTAL OIL AND GAS RESERVE INFORMATION (UNAUDITED)
 
   
     The estimates of proved oil and gas reserves, which are located principally
in the United States, were prepared by the Company as of December 31, 1995, and
Williamson Petroleum Consultants as of September 30, 1996. Reserves were
estimated in accordance with guidelines established by the SEC and FASB which
require that reserve estimates be prepared under existing economic and operating
conditions with no provision for price and cost escalations except by
contractual arrangements. The Company has presented the reserve estimates
utilizing an oil price of $16.78 per Bbl and a gas price of $1.20 per Mcf as of
December 31, 1995 and an oil price of $23.36 per Bbl and a gas price of $1.32
per Mcf as of September 30, 1996.
    
 
  Oil and Gas Producing Activities
 
     Oil and gas reserve quantity estimates are subject to numerous
uncertainties inherent in the estimation of quantities of proved reserves and in
the projection of future rates of production and the timing of development
expenditures. The accuracy of such estimates is a function of the quality of
available data and of engineering and geological interpretation and judgment.
Results of subsequent drilling, testing and production may cause either upward
or downward revision of previous estimates. Further, the volumes considered to
be commercially recoverable fluctuate with changes in prices and operating
costs. The Company emphasizes that reserve estimates are inherently imprecise
and that estimates of new discoveries are more imprecise than those of currently
producing oil and gas properties. Accordingly, these estimates are expected to
change as additional information becomes available in the future.

 Standardized Measure of Discounted Future Net Cash Flows of Proved Oil and Gas
 Reserves
 
     The standardized measure of discounted future net cash flows is computed by
applying year-end prices of oil and gas (with consideration of price changes
only to the extent provided by contractual arrangements) to the estimated future
production of proved oil and gas reserves, less estimated future expenditures
(based on period-end costs) to be incurred in developing and producing the
proved reserves, less estimated future income tax expenses (based on period-end
statutory tax rates, with consideration of future tax rates already legislated)
to be incurred on pretax net cash flows less tax basis of the properties and
available credits, and assuming continuation of existing economic conditions.
The estimated future net cash flows are then discounted using a rate of 10% per
year to reflect the estimated timing of the future cash flows.
 
     Discounted future cash flow estimates like those shown below are not
intended to represent estimates of the fair value of oil and gas properties.
Estimates of fair value should also consider probable reserves, anticipated
future oil and gas prices, interest rates, changes in development and production
costs and risks associated with future production. Because of these and other
considerations, any estimate of fair value is necessarily subjective and
imprecise.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Titan Exploration, Inc.:
 
     We have audited the accompanying statements of revenues and direct
operating expenses of the oil and gas properties acquired (1995 Acquisition) by
Titan Exploration, Inc. for the years ended December 31, 1993 and 1994 and the
period ended December 11, 1995. These statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
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 statements of revenues and direct
operating expenses 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 statement presentation. We believe that our audits
provide a reasonable basis for our opinion.
 
     The accompanying statements of revenues and direct operating expenses were
prepared for the purpose of complying with the rules and regulations of the
Securities and Exchange Commission (for inclusion in Form S-1 of Titan
Exploration, Inc. as described in Note 1) and are not intended to be a complete
presentation of the 1995 Acquisition revenues and expenses.
 
     In our opinion, the statements of revenues and direct operating expenses
referred to above present fairly, in all material respects, the revenues and
direct operating expenses of the 1995 Acquisition for the years ended December
31, 1993 and 1994 and the period ended December 11, 1995 in conformity with
generally accepted accounting principles.

       NOTES TO THE STATEMENTS OF REVENUES AND DIRECT OPERATING EXPENSES
 
(1) BASIS OF PRESENTATION
 
     On December 11, 1995, Titan Exploration, Inc. (the "Company") acquired from
a large independent oil and gas company certain oil and gas properties (the
"1995 Acquisition") for $39,881,094. The accompanying statements of revenues and
direct operating expenses for the 1995 Acquisition do not include general and
administrative expenses, interest income or expense, a provision for
depreciation, depletion and amortization, or any provision for income taxes
since historical expenses of this nature incurred by Anadarko are not
necessarily indicative of the costs to be incurred by the Company.
 
   
     Historical financial information reflecting financial position, results of
operations, and cash flows of the 1995 Acquisition, are not presented because
the purchase price was assigned to the oil and gas property interests acquired.
Other assets acquired and liabilities assumed were not material. In addition,
the properties acquired were a part of a much larger enterprise prior to
acquisition by the Company and representative amounts of general and
administrative expenses, depreciation, depletion and amortization, interest and
other indirect costs were not necessarily allocated to the specific properties
acquired, nor would such allocated historical costs be relevant to future
operations of the properties. Development and exploration expenditures related
to these properties have been insignificant in the relevant periods.
Accordingly, the historical statements of revenues and direct operating expenses
of the 1995 Acquisition are presented in lieu of the financial statements
required under Rule 3-05 of Securities and Exchange Commission Regulation S-X.
    
 
     Revenues in the accompanying statements of revenues and direct operating
expenses are recognized on the sales method. Under this method, revenues are
recognized based on actual volumes of oil and gas sold to purchasers. Direct
operating expenses are recognized on the accrual method.
 
(2) SUPPLEMENTARY FINANCIAL INFORMATION FOR OIL AND GAS PRODUCING ACTIVITIES
(UNAUDITED)
 
  Estimated Quantities of Proved Oil and Gas Reserves
 
     Reserve information presented below is based on reserve estimates prepared
by the Company.
 
     Proved reserves are estimated quantities of crude oil and natural gas which
geological and engineering data demonstrate with reasonable certainty to be
recoverable in future years from known reservoirs under existing economic and
operating conditions. Proved developed reserves are those which are expected to
be recovered through existing wells with existing equipment and operating
methods. Oil and gas reserve quantity estimates are subject to numerous
uncertainties inherent in the estimation of quantities of proved reserves and in
the projection of future rates of production and the timing of development
expenditures. The accuracy of such estimates is a function of the quality of
available data and of engineering and geological interpretation and judgment.
Results of subsequent drilling, testing and production may cause either upward
or downward revision of previous estimates. Further, the volumes considered to
be commercially recoverable fluctuate with changes in prices and operating
costs. The Company emphasizes that reserve estimates are inherently imprecise
and that estimates of new discoveries are more imprecise than those of currently
producing oil and gas properties. Accordingly, these reserve estimates are
expected to change as additional information becomes available in the future.

  Standardized Measure of Discounted Future Net Cash Flows of Proved Oil and Gas
Reserves
 
     The Company has estimated the standardized measure of discounted future net
cash flows and changes therein relating to proved oil and gas reserves in
accordance with the standards established by the Financial Accounting Standards
Board through its Statement No. 69. The estimates of future cash flows and
future production and development costs are based on period-end sales prices for
oil and gas, estimated future production of proved reserves, and estimated
future production and development costs of proved reserves, based on current
costs and economic conditions. The estimated future net cash flows are then
discounted at a rate of 10%.
 
     Discounted future net cash flow estimates like those shown below are not
intended to represent estimates of the fair market value of oil and gas
properties. Estimates of fair market value should also consider probable
reserves, anticipated future oil and gas prices, interest rates, changes in
development and production costs and risks associated with future production.
Because of these and other considerations, any estimate of fair market value is
necessarily subjective and imprecise.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Titan Exploration, Inc.:
 
     We have audited the accompanying statements of revenues and direct
operating expenses of the oil and gas properties to be acquired (1996
Acquisition) by Titan Exploration Inc. for the years ended December 31, 1993,
1994 and 1995. 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 audits to obtain
reasonable assurance about whether the statements of revenues and direct
operating expenses 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 statement presentation. We believe that our audits
provide a reasonable basis for our opinion.
 
     The accompanying statements of revenues and direct operating expenses were
prepared for the purpose of complying with the rules and regulations of the
Securities and Exchange Commission (for inclusion in Form S-1 of Titan
Exploration, Inc. as described in Note 1) and are not intended to be a complete
presentation of the 1996 Acquisition revenues and expenses.
 
     In our opinion, the statements of revenues and direct operating expenses
referred to above present fairly, in all material respects, the revenues and
direct operating expenses of the 1996 Acquisition for the years ended December
31, 1993, 1994 and 1995 in conformity with generally accepted accounting
principles.

       NOTES TO THE STATEMENTS OF REVENUES AND DIRECT OPERATING EXPENSES
 
(1) BASIS OF PRESENTATION
 
   
     On October 31, 1996, Titan Exploration, Inc. (the "Company") acquired from
a major integrated company certain oil and gas properties located in the Permian
Basin (the "1996 Acquisition") for $135,524,139. The accompanying statements of
revenues and direct operating expenses for the 1996 Acquisition do not include
general and administrative expenses, interest income or expense, a provision for
depreciation, depletion and amortization, or any provision for income taxes
since historical expenses of this nature incurred by Mobil are not necessarily
indicative of the costs to be incurred by the Company.
    
 
   
     Historical financial information reflecting financial position, results of
operations, and cash flows of the 1996 Acquisition, are not presented because
the purchase price will be assigned to the oil and gas property interests
acquired. Other assets acquired and liabilities assumed were not material. In
addition, the properties acquired were a part of a much larger enterprise prior
to acquisition by the Company and representative amounts of general and
administrative expenses, depreciation, depletion and amortization, interest and
other indirect costs were not necessarily allocated to the specific properties
acquired, nor would such allocated historical costs be relevant to future
operations of the properties. Development and exploration expenditures related
to these properties have been insignificant in the relevant periods.
Accordingly, the historical statements of revenues and direct operating expenses
of the 1996 Acquisition are presented in lieu of the financial statements
required under Rule 3-05 of Securities and Exchange Commission Regulation S-X.
    
 
     Revenues in the accompanying statements of revenues and direct operating
expenses are recognized on the sales method. Under this method, revenues are
recognized based on actual volumes of oil and gas sold to purchasers. Direct
operating expenses are recognized on the accrual basis.
 
   
     The financial information for the nine months ended September 30, 1995 and
1996, is unaudited. However, in the opinion of management, the statements of
revenues and direct operating expenses for the nine months ended September 30,
1995 and 1996 include all the necessary adjustments to fairly present the
results of these periods.
    
 
(2) SUPPLEMENTARY FINANCIAL INFORMATION FOR OIL AND GAS PRODUCING ACTIVITIES
(UNAUDITED)
 
  Estimated Quantities of Proved Oil and Gas Reserves
 
     Reserve information presented below is based on reserve estimates prepared
by the Company.
 
     Proved reserves are estimated quantities of crude oil and natural gas which
geological and engineering data demonstrate with reasonable certainty to be
recoverable in future years from known reservoirs under existing economic and
operating conditions. Proved developed reserves are those which are expected to
be recovered through existing wells with existing equipment and operating
methods. Oil and gas reserve quantity estimates are subject to numerous
uncertainties inherent in the estimation of quantities of proved reserves and in
the projection of future rates of production and the timing of development
expenditures. The accuracy of such estimates is a function of the quality of
available data and of engineering and geological interpretation and judgment.
Results of subsequent drilling, testing and production may cause either upward
or downward revision of previous estimates. Further, the volumes considered to
be commercially recoverable fluctuate with changes in prices and operating
costs. The Company emphasizes that reserve estimates are inherently imprecise
and that estimates of new discoveries are more imprecise than those of currently
producing oil and gas properties. Accordingly, these reserve estimates are
expected to change as additional information becomes available in the future.

  Standardized Measure of Discounted Future Net Cash Flows of Proved Oil and Gas
Reserves
 
     The Company has estimated the standardized measure of discounted future net
cash flows and changes therein relating to proved oil and gas reserves in
accordance with the standards established by the Financial Accounting Standards
Board through its Statement No. 69. The estimates of future cash flows and
future production and development costs are based on period-end sales prices for
oil and gas, estimated future production of proved reserves, and estimated
future production and development costs of proved reserves, based on current
costs and economic conditions. The estimated future net cash flows are then
discounted at a rate of 10%.
 
     Discounted future net cash flow estimates like those shown below are not
intended to represent estimates of the fair market value of oil and gas
properties. Estimates of fair market value should also consider probable
reserves, anticipated future oil and gas prices, interest rates, changes in
development and production costs and risks associated with future production.
Because of these and other considerations, any estimate of fair market value is
necessarily subjective and imprecise.

Gentlemen:
 
   
Subject: Summary Letter (for Inclusion in a Prospectus Included in a
         Registration Statement for Titan Exploration, Inc. on Form S-1)
         Combining Specific Data from Two Williamson Petroleum Consultants, Inc.
         Evaluations (1) to the Interests of Titan Exploration, Inc. in Titan
         Original Properties and Properties Acquired from a Large Independent
         Oil Company in 1995, Effective October 1, 1996 (the 1995 Acquisition
         Properties) and (2) to the Interests in Properties Acquired from a
         Major Integrated Oil and Gas Company (the Integrated Company),
         Effective October 1, 1996 (the 1996 Acquisition Properties), for
         Disclosure to the Securities and Exchange Commission, Williamson
         Project 6.8432
    
 
     In accordance with your request, Williamson Petroleum Consultants, Inc.
(Williamson) has prepared a summary letter for inclusion in a prospectus for
Titan Exploration, Inc. (Titan). This summary letter includes specific data from
two evaluations the subjects of which are described in Item I. All values and
discussion of proved reserves and net revenues, data utilized, assumptions, and
qualifications are taken from and include by reference data from these two
evaluations.
 
   
     Interests in this summary letter represent the October 1, 1996 effective
date consolidation of the ownership interests of Titan and the ownership
interests purchased from the Integrated Company in various properties included
in the March 1996 Permian Basin Divestiture Package. The Titan properties
include interests in those properties designated as the Titan original
properties and the 1995 Acquisition Properties purchased by Titan in 1995. Titan
concluded the purchase of the 1996 Acquisition Properties on October 31, 1996.
The evaluation of the 1996 Acquisition Properties with an effective date of
October 1, 1996 and the summation with the Titan properties herein is based on
the October 31, 1996 closing on the 1996 Acquisition Properties.
    
 
I. THE TWO SUBJECT EVALUATIONS
 
     This summary letter combines certain proved oil and gas reserves and
revenues from the following two Williamson evaluations:
 
          (1) Evaluation of Oil and Gas Reserves to the Interests of Titan
     Exploration, Inc. in Titan Original Properties and 1995 Acquisition
     Properties, Effective October 1, 1996, for Disclosure to the Securities and
     Exchange Commission, Williamson Project 6.8432 (the Titan report)
 
   
          (2) Evaluation of Oil and Gas Reserves to the Interests in the 1996
     Acquisition Properties, Effective October 1, 1996, for Disclosure to the
     Securities and Exchange Commission, Williamson Project 6.8432 (the 1996
     Acquisition report)
    
 
II. ESTIMATED SEC RESERVES AND FUTURE NET REVENUES
 
     Projections of the reserves that are attributable to the consolidated
interests in this summary letter were based on economic parameters and operating
conditions considered applicable as of October 1, 1996 and are pursuant to the
requirements of the Securities and Exchange Commission (SEC).
 
                                       A-1

     The present values of the estimated future net revenues from proved
reserves were calculated using a discount rate of 10.00 percent per year and
were computed in accordance with the financial reporting requirements of the
SEC. Following is a summary of the results of the two evaluations effective
October 1, 1996:

Note: The values presented in this table are taken from the evaluations
      described in Item I and include by reference all data, qualifications, and
      assumptions from these evaluations. Realization of these values is
      contingent on achieving successful results from the various schedules and
      assumptions in these evaluations. The available engineering data and the
      completeness and/or quality of data utilized in evaluating the properties
      are detailed in the specific evaluation. Review of any additionally
      available data may necessitate revision to these interpretations and
      assumptions and impact these values.
 
III. DEFINITIONS OF SEC RESERVES(1)
 
     The estimated reserves presented in this summary letter are net proved
reserves, including proved developed producing, proved developed nonproducing,
and proved undeveloped reserves, and were computed in accordance with the
financial reporting requirements of the SEC. In preparing these evaluations, no
attempt has been made to quantify the element of uncertainty associated with any
category. Reserves were assigned to each category as warranted. The definitions
of oil and gas reserves pursuant to the requirements of the Securities Exchange
Act are:
 
  Proved Reserves(2)
 
     Proved reserves are the estimated quantities of crude oil, natural gas, and
natural gas liquids which geological and engineering data demonstrate with
reasonable certainty to be recoverable in future years from known reservoirs
under the economic criteria employed and existing operating conditions, i.e.,
prices and costs as of the date the estimate is made. Prices and costs include
consideration of changes provided only by contractual arrangements but not on
escalations based upon an estimate of future conditions.
 
     A. Reservoirs are considered proved if economic producibility is supported
by either actual production or conclusive formation test. The area of a
reservoir considered proved includes:
 
          1. that portion delineated by drilling and defined by gas-oil and/or
     oil-water contacts, if any; and
 
          2. the immediately adjoining portions not yet drilled, but which can
     be reasonably judged as economically productive on the basis of available
     geological and engineering data. In the absence of information on fluid
     contacts, the lowest known structural occurrence of hydrocarbons controls
     the lower proved limit of the reservoir.
 
     B. Reserves which can be produced economically through application of
improved recovery techniques (such as fluid injection) are included in the
"proved" classification when successful testing by a pilot project,

    Commission, see SEC Accounting Rules. Commerce Clearing House, Inc. October
    1981, Paragraph 290, Regulation 210.4-10, p. 329.
 
(2) Any variations to these definitions will be clearly stated in the report.
 
                                       A-2

or the operation of an installed program in the reservoir, provides support for
the engineering analysis on which the project or program was based.
 
     C. Estimates of proved reserves do not include the following:
 
          1. oil that may become available from known reservoirs but is
     classified separately as "indicated additional reserves";
 
          2. crude oil, natural gas, and natural gas liquids, the recovery of
     which is subject to reasonable doubt because of uncertainty as to geology,
     reservoir characteristics, or economic factors;
 
          3. crude oil, natural gas, and natural gas liquids, that may occur in
     undrilled prospects; and
 
          4. crude oil, natural gas, and natural gas liquids, that may be
     recovered from oil shales, coal(3), gilsonite, and other such sources.
 
  Proved Developed Reserves(4)
 
     Proved developed reserves are reserves that can be expected to be recovered
through existing wells with existing equipment and operating methods. Additional
oil and gas expected to be obtained through the application of fluid injection
or other improved recovery techniques for supplementing the natural forces and
mechanisms of primary recovery should be included as "proved developed reserves"
only after testing by a pilot project or after the operation of an installed
program has confirmed through production response that increased recovery will
be achieved.
 
  Proved Undeveloped Reserves
 
     Proved undeveloped reserves are reserves that are expected to be recovered
from new wells on undrilled acreage, or from existing wells where a relatively
major expenditure is required for recompletion. Reserves on undrilled acreage
shall be limited to those drilling units offsetting productive units that are
reasonably certain of production when drilled. Proved reserves for other
undrilled units can be claimed only where it can be demonstrated with certainty
that there is continuity of production from the exiting productive formation.
Under no circumstances should estimates for proved undeveloped reserves be
attributable to any acreage for which an application of fluid injection or other
improved recovery technique is contemplated, unless such techniques have been
proved effective by actual tests in the area and in the same reservoir.
 
IV. DISCUSSION OF SEC RESERVES
 
  A. The Titan Report
 
     A total of 113 properties in 44 fields were evaluated in the Titan report.
These properties are located in the states of New Mexico and Texas with the
majority of value in Texas. Overall net reserves are 6,562,947 barrels of oil
(BO) and 179,564,506 thousand cubic feet of gas (MCF) or 36,490,365 barrels of
oil equivalent (BOE) at a conversion rate of six MCF of gas to one BO.
Associated future net revenue discounted at 10.00 percent per annum (DFNR) is
$144,531,504. Five fields in Texas represent a combined DFNR of $101,371,218 or
approximately 70.14 percent of the total Titan DFNR. These five fields are, in
descending order of DFNR, Puckett field, Pecos County, Texas; Foster field,
Ector County, Texas; Barstow field, Ward County, Texas; Gomez field, Pecos
County, Texas; and Evetts field, Loving and Winkler Counties, Texas. These
fields include 18 properties in the proved developed category and ten properties
in the proved

(3) According to Staff Accounting Bulletin 85, excluding certain coalbed methane
    gas.
 
(4) Williamson Petroleum Consultants, Inc. separates proved developed reserves
    into proved developed producing and proved developed nonproducing reserves.
    This is to identify proved developed producing reserves as those to be
    recovered from actively producing wells; proved developed nonproducing
    reserves as those to be recovered from wells or intervals within wells,
    which are completed but shut in waiting on equipment or pipeline
    connections, or wells where a relatively minor expenditure is required for
    recompletion to another zone.
 
                                       A-3

undeveloped category. The proved developed properties contribute $41,128,552
DFNR while the proved undeveloped properties in these five fields contribute
$60,242,666 DFNR. A more detailed property review is included in the Titan
report.
 
     Prices for oil were based on data available as of September 26, 1996 and
were used as effective date prices. Prices were based on posted prices as of
September 26, 1996 and associated premiums being paid by the pipeline purchaser
or trucking purchaser for West Texas intermediate or West Texas sour crude oil.
Information pertaining to postings, premiums, purchaser, and quality of crude
oil were provided by Titan. When not provided, Williamson estimated oil prices
by analogy to similar properties. After the effective date, prices were held
constant for the life of the properties. The overall average oil price for all
properties was $23.36 per BO. No attempt has been made to account for oil price
fluctuations which have occurred in the market subsequent to the effective date
of the report.
 
     The 1995 Acquisition Properties are subject to a hedging contract. This
hedging contract results in a penalty on oil sales through December 31, 1996.
Titan estimated the amount of these penalties and provided Williamson the
projected amount of dollars lost during October, November, and December 1996.
These negative dollars were included on a "Cost Tract" and deducted from the
total future net revenue.
 
     Gas prices based on September 1996 prices or indexes were provided by Titan
and were used as effective date prices. After the effective date, prices were
held constant for the life of the properties. All gas prices were applied to
projected wellhead volumes. To account for known differences between sales and
produced volumes, any given residue gas sales price was adjusted by a factor in
order to make the price applicable to the wellhead stream. Similar adjustments
were made to account for any known lease use. Gas prices were also adjusted for
any known income from plant products not projected separately. When not
provided, Williamson estimated gas prices by analogy to similar properties. The
overall average gas price for all properties was $1.324 per MCF.
 
     State production taxes have been deducted at the published rates as
appropriate. Ad valorem taxes were deducted based on information provided by
Titan or on published rates.
 
  B. The 1996 Acquisition Report
 
   
     A total of 142 properties in 54 fields were evaluated in the 1996
Acquisition report. These properties are located in the states of New Mexico and
Texas with the majority of value in Texas. Overall net reserves are 11,279,950
BO and 101,258,565 MCF of gas or 28,156,378 BOE. Associated DFNR is
$147,548,183. Five fields/areas in Texas and one area in New Mexico have a
combined DFNR of $97,551,043 or approximately 66.11 percent of the total
Integrated Company DFNR. These fields/areas are, in descending order of DFNR:
East Dollarhide field, Andrews County, Texas; Mi Vida field, Ward and Reeves
Counties, Texas; North Robertson field, Gaines County, Texas; Eunice field area,
Lea County, New Mexico; University Waddell field, Crane County, Texas; and
Headlee (Devonian) field, Ector County, Texas. These fields/areas include 34
properties in the proved developed producing category and 10 properties
classified as proved undeveloped. The proved developed producing category
contributes $78,479,044 DFNR while the proved undeveloped properties contribute
$19,071,999 DFNR. A more detailed property review is included in the 1996
Acquisition report.
    
 
   
     Oil prices were provided by Titan and were used as effective date prices.
These were reported to be the Integrated Company's posted prices received by the
Integrated Company on September 26, 1996 for all properties they operate or in
which they retain a nonoperating working interest. These prices were used for
October and November 1996. Starting December 1, 1996, oil prices were set at the
Enron Oil Trading and Transportation Energy Operating Limited Partnership (EOTT)
postings as of September 26, 1996 plus premiums in accordance with a contract
for EOTT to purchase oil from Titan on the 1996 Acquisition Properties starting
December 1, 1996. On properties not covered by EOTT, the price at December 1,
1996 was set at prices consistent with September postings plus premiums for
trucked oil. When not provided, Williamson estimated oil prices by analogy to
similar properties. After December 1, 1996, prices were held constant for the
life of the properties. The overall average oil price for all properties was
$23.37 per BO. No
    
 
                                       A-4
<PAGE>   100
 
attempt has been made to account for oil price fluctuations which have occurred
in the market subsequent to the effective date of the report.
 
   
     Gas prices based on September 1996 prices or indexes were provided by Titan
and were used as effective date prices. After the effective date, prices were
held constant for the life of the properties. All gas prices were applied to
projected wellhead volumes. To account for known differences between sales and
produced volumes, any given residue gas sales price was adjusted by a factor in
order to make the price applicable to the wellhead stream. Similar adjustments
were made to account for any known lease use. Gas prices were also adjusted for
any known income from plant products not projected separately. When not
provided, Williamson estimated gas prices by analogy to similar properties. The
overall average gas price for all properties was $1.513 per MCF.
    
 
     State production taxes have been deducted at the published rates as
appropriate. Ad valorem taxes were deducted based on information provided by
Titan or on published rates for all operated properties. On properties not
operated by the Integrated Company, ad valorem taxes were provided by Titan or,
if not provided, were assumed to be included in the operating costs.
 
V. GENERAL EVALUATION CONSIDERATIONS PERTAINING TO THE TITAN AND 1996
ACQUISITION REPORTS
 
     The individual projections prepared to produce this summary letter include
data that describe the production forecasts and associated evaluation parameters
such as interests, taxes, product prices, operating costs, investments, salvage
values, abandonment costs, and net profit interests, as applicable.
 
     Net income to the evaluated interests is the future net revenue after
consideration of royalty revenue payable to others, taxes, operating expenses,
investments, salvage values, abandonment costs, and net profit interests, as
applicable. The future net revenue is before federal income tax and excludes
consideration of any encumbrances against the properties if such exist.
 
     No opinion is expressed by Williamson as to the fair market value of the
evaluated properties.
 
     The future net revenue values presented in this summary letter were based
on projections of oil and gas production. It was assumed there would be no
significant delay between the date of oil and gas production and the receipt of
the associated revenue for this production.
 
     This summary letter includes only those costs and revenues which are
considered by Titan to be directly attributable to individual leases and areas.
There could exist other revenues, overhead costs, or other costs associated with
Titan or the Integrated Company which are not included in this summary letter.
Such additional costs and revenues are outside the scope of this summary letter.
This summary letter is not a financial statement for Titan and should not be
used as the sole basis for any transaction concerning Titan, the Integrated
Company, or the evaluated properties.
 
     The reserves projections in this summary letter are based on the use of the
available data and accepted industry engineering methods. Future changes in any
operational or economic parameters or production characteristics of the
evaluated properties could increase or decrease their reserves. Unforeseen
changes in market demand or allowables set by various regulatory agencies could
also cause actual production rates to vary from those projected. The dates of
first production for nonproducing properties were based on estimates by Titan or
Williamson and the actual dates may vary from those estimated. Williamson
reserves the right to alter any of the reserves projections and the associated
economics included in this summary letter in any future evaluations based on
additional data that may be acquired.
 
     All data utilized in the preparation of this summary letter with respect to
interests, reversionary status, oil and gas prices, gas categories, gas contract
terms, operating expenses, investments, salvage values, abandonment costs, net
profit interests, well information, and current operating conditions, as
applicable, were provided by Titan and the operators. Production data from
public records were used where available. If public records were not available,
production data provided by Titan and various other operators were utilized.
Production data generally through February or June 1996 were obtained for the
properties in the Titan report and through January or June 1996 for the
properties in the 1996 Acquisition report. Additional production
 
                                       A-5
<PAGE>   101
 
data for the months of July or August were provided by Titan or the operators on
various properties. All data have been reviewed for reasonableness and, unless
obvious errors were detected, have been accepted as correct. It should be
emphasized that revisions to the projections of reserves and economics included
in this summary letter may be required if the provided data are revised for any
reason. No inspection of the properties was made as this was not considered
within the scope of these projects. No investigation was made of any
environmental liabilities that might apply to the evaluated properties, and no
costs are included for any possible related expenses.
 
     Operating expenses were provided by Titan and represented, when possible,
the latest available 12- to 18-month average of all recurring expenses which are
billable to the working interest owners. These expenses included, but were not
limited to, all direct operating expenses, field overhead costs, and any ad
valorem taxes not deducted separately. Expenses for workovers, well
stimulations, and other maintenance were not included in the operating expenses
unless such work was expected on a recurring basis. Judgments for the exclusion
of the nonrecurring expenses were made by Titan. The economic limit for each
property was determined using these costs. Any internal indirect overhead costs
(general and administrative) which are billable to the working interest owners
were included, while those not billable were not included. For new and
developing properties where data were unavailable, operating expenses were
estimated by Titan or Williamson based on analogy with similar properties.
Operating costs were held constant for the life of the properties.
 
     Unless specifically identified and documented by Titan as having
curtailment problems, gas production trends have been assumed to be a function
of well productivity and not of market conditions. The effect of "take or pay"
clauses in gas contracts was not considered.
 
     Oil reserves are expressed in United States (U.S.) barrels of 42 U.S.
gallons. Gas volumes are expressed in MCF's at 60 degrees Fahrenheit and at the
legal pressure base that prevails in the state in which the reserves are
located. No adjustment of the individual gas volumes to a common pressure base
has been made.
 
     Titan represented to Williamson that it has, or can generate, the financial
and operational capabilities to accomplish those projects evaluated by
Williamson which require capital expenditures.
 
     All capital costs for drilling and completion of wells and nonrecurring
workover or operating costs have been deducted as applicable. These costs were
provided by Titan or, where not supplied, were estimated by Williamson. No
adjustments were made to account for the potential effect of inflation on these
costs.
 
     Neither salvage values nor abandonment costs were provided by Titan to be
included in this evaluation.
 
     The estimates of reserves contained in this summary letter were determined
by accepted industry methods and in accordance with the definitions of oil and
gas reserves set forth above. Methods utilized in this summary letter include
extrapolation of historical production trends, material balance determinations,
analogy to similar properties, and volumetric calculations.
 
     Where sufficient production history and other data were available, reserves
for producing properties were determined by extrapolation of historical
production trends or through the use of material balance determinations. Analogy
to similar properties or volumetric calculations were used for nonproducing
properties and those producing properties which lacked sufficient production
history and other data to yield a definitive estimate of reserves. Reserves
projections based on analogy are subject to change due to subsequent changes in
the analogous properties or subsequent production from the evaluated properties.
Volumetric calculations are often based upon limited log and/or core analysis
data and incomplete reservoir fluid and formation rock data. Since these limited
data must frequently be extrapolated over an assumed drainage area, subsequent
production performance trends or material balance calculations may cause the
need for significant revisions to the estimates of reserves.
 
     It should be emphasized that with the current economic uncertainties,
fluctuation in market conditions could significantly change the economics in
this summary letter.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 102(b)(7) of the Delaware General Corporation Law ("DGCL") enables
a corporation to include in its certificate of incorporation a provision
eliminating or limiting the personal liability of members of its Board of
Directors to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director. Such a provision may not eliminate or limit the
liability of a director (1) for any breach of a director's duty of loyalty to
the corporation or its stockholders, (2) for acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of a law, (3) for
paying an unlawful dividend or approving an illegal stock repurchase (as
provided in Section 174 of the DGCL), or (4) for any transaction from which the
director derived an improper personal benefit.
 
     Under Section 145 of the DGCL, a corporation has the power to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding (other than an
action by or in the right of the corporation) by reason of the fact that the
person is or was a director, officer, employee or agent of any corporation,
partnership, joint venture, trust or other enterprise, against any and all
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement and reasonably incurred in connection with such action, suit or
proceeding. The power to indemnify applies only if the person acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and with respect to any criminal action or
proceeding, had no reasonable cause to believe the person's conduct was
unlawful.
 
     In the case of an action by or in the right of the corporation, no
indemnification may be made with respect to any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine that despite the adjudication of
liability such person is fairly and reasonably entitled to indemnity for such
expenses which the court shall deem proper. Section 145 of the DGCL further
provides that to the extent a director or officer of a corporation has been
successful in the defense of any action, suit or proceeding referred to above or
in the defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorney's fees) actually and reasonably incurred by
him in connection therewith.
 
     A corporation also has the power to purchase and maintain insurance on
behalf of any person covering any liability incurred by such person in his
capacity as a director, officer, employee or agent of the corporation,
 
                                      II-1
<PAGE>   105
 
or arising out of his status as such, whether or not the corporation would have
the power to indemnify him against such liability.
 
     The Registrant's Certificate of Incorporation and Bylaws provide that no
director of the Registrant will be personally liable to the Registrant or any of
its stockholders for monetary damages arising from the director's breach of
fiduciary duty as a director. However, this does not apply with respect to any
action in which the director would be liable under Section 174 of Title 8 of the
DGCL nor does it apply with respect to any liability in which the director (i)
breached his duty of loyalty to the Registrant; (ii) did not act in good faith
or, in failing to act, did not act in good faith; (iii) acted in a manner
involving intentional misconduct or a knowing violation of law or, in failing to
act, shall have acted in a manner involving intentional misconduct or a knowing
violation of law; or (iv) derived an improper personal benefit.
 
     The Certificate of Incorporation and Bylaws provide that the Registrant
will indemnify its officers and directors and former officers and directors
against any expenses, judgments or settlement payments sustained or paid by such
persons as a result of having acted as an officer or director of the Registrant,
or, at the request of the Registrant, as an officer, director, agent or employee
of another business entity. The Certificate of Incorporation and Bylaws further
provide that the Registrant may, by action of its Board of Directors, provide
indemnification to employees and agents of the Registrant, individually or as a
group, with the same scope and effect as the indemnification of directors and
officers.
 
     The form of Indemnity Agreement contained in Exhibit 10.23 provides for the
indemnification in certain instances against liability and expenses incurred in
connection with proceedings brought by or in the right of the Company or by
third parties by reason of a person serving as an officer or director of the
Company.
 
     The form of Underwriting Agreement contained in Exhibit 1 provides for
indemnification of the directors and officers signing the Registration Statement
and certain controlling persons of the Company against certain liabilities
(including certain liabilities under the Securities Act of 1933, as amended (the
"Securities Act")) in certain instances by the Underwriters.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
     The following information relates to all securities issued or sold by the
Registrant since inception and not registered under the Securities Act.
 
     Unless otherwise specifically provided, each of the transactions described
below was conducted in reliance upon the exemption from registration provided in
Section 4(2) of the Securities Act and the rules and regulations promulgated
thereunder. Furthermore, each of the certificates representing the Registrant's
securities issued in connection with such transactions contains a restrictive
legend, as appropriate, requiring each person acquiring such securities from the
Registrant to furnish investment representations to the Registrant and stating
that no underwriters participated in such transactions.
 
   
     The Registrant was formed on September 27, 1996 pursuant to the terms of an
Agreement and Plan of Reorganization dated September 30, 1996 (the "Exchange
Agreement"). Pursuant to the terms of the Exchange Agreement, the Company became
the holding company for Titan Resources, L.P., which conducts the Registrant's
operations and was formed on March 31, 1995 (the "Partnership"). Pursuant to the
terms of the Exchange Agreement, the limited partners of the Partnership
received approximately .665 shares of the Registrant's common stock for each
limited partnership unit owned by such limited partners. Each certificate issued
in connection with such exchange contains an appropriate restrictive legend. All
of the information regarding sales of the Registrant's securities set forth
below has been adjusted to give effect to the exchange.
    
 
   
     On March 31, 1995, the Partnership was formed pursuant to the terms and
conditions of a Partnership Agreement between Titan Resources, I, Inc., as
general partner, and 20 limited partners, which provided for the issuance of
partnership units equivalent to 13,755,998 shares of the Registrant's Common
Stock, par value $.01 per share, for an aggregate purchase price of $20,547,980.
    
 
   
     On December 11, 1995, the Partnership entered into a Stock and Unit
Purchase Agreement with Joint Energy Development Investments Limited
Partnership, providing for the sale by the Partnership of partner-
    
 
                                      II-2

ship units equivalent to 3,381,046 shares of the Registrant's Common Stock, par
value $.01 per share, for an aggregate purchase price of $10,000,000.
    
 
   
     On December 11, 1995, the Partnership entered into a Stock and Unit
Purchase Agreement with First Union Corporation, providing for the sale by the
Partnership of partnership units equivalent to 1,690,523 shares of the
Registrant's Common Stock, par value $.01 per share, for an aggregate purchase
price of $5,000,000.
    
 
   
     On September 27, 1996, the Partnership entered into an Unit Purchase and
Exchange Agreement with Selma International Investment Limited, providing for
the sale by the Partnership of partnership units equivalent to 722,446 shares of
the Registrant's Common Stock, par value $.01 per share, for an aggregate
purchase price of $5,000,000.
    
 
   
     Since inception, the Registrant and its predecessor have granted options to
purchase an aggregate of 3,716,350 shares of Common Stock to officers and key
employees. These transactions did not involve a public offering and were done in
reliance on Section 4(2) of the Securities Act.

ITEM 17. UNDERTAKINGS
 
     The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreements, certificates in such
denominations and registered in such names as required by the particular
Underwriter, to permit prompt delivery to each purchaser.
 
     The undersigned Registrant also hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose 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.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the 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 or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the
 
                                      II-5

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.

         WHEREAS, promptly after the consummation of the Proposed Transaction,
the Company and/or the Partnership plans to employ the Employee on an "at-will"
basis, and the Employee desires to be employed on such basis;

         WHEREAS, Employee acknowledges that in the course of his employment by

economic and trade secrets and relationships of the Related Parties;

         WHEREAS, it is a condition to (i) the consummation of the Proposed
Transaction, (ii) the grant to Employee of the Options, and (iii) the

or not patentable or copyrightable, which do not fall within the definition of
Business Opportunities, which the Employee discovers, conceives, invents,
creates, or develops, alone or with others, during the Employment Term, if such
discovery, conception, invention, creation, or development (i) occurs in the
course of the Employee's employment with the Company, or (ii) occurs with the
use of any of the Related Parties' time, materials, or facilities, or (iii) in
the opinion of the Board of Directors of the Company, relates or pertains in
any way to the Related Parties' purposes, activities, or affairs;

         2.      Non-Compete Obligations During Employment Term. Employee

         indirectly through any family member or as an employee, employer,
         consultant, agent, principal, partner, more than one percent

participate in the acquisition, exploration or development of any acreage which
is not currently included in the Existing Personal Investments as of the date
hereof, unless such opportunity is first offered to, and subsequently declined
by, the Partnership.

         3.      Confidentiality Obligations.

         (a)     Employee hereby acknowledges that all trade secrets and
confidential or proprietary information of the Related Parties (collectively
referred to herein as "CONFIDENTIAL INFORMATION") constitutes valuable, special
and unique assets of the Related Parties' business, and that access to and
knowledge of such Confidential Information is essential to the performance of
Employee's duties hereunder. Employee agrees that during the Employment Term
and during the one year period following the date of termination of Employee's
employment by the Related Parties (the "TERMINATION DATE"), Employee will hold
the Confidential Information in strict confidence and will not publish,
disseminate or otherwise disclose, directly or indirectly, to any person other
than the Related Parties and their respective officers, directors and
employees, any Confidential Information or use any Confidential Information for
Employee's own personal benefit or for the benefit of anyone other than the
Related Parties.

         (b)     For purposes of this Section 3, it is agreed that Confidential
Information includes, without limitation, any information heretofore or
hereafter acquired, developed or used by any of the Related Parties relating to
Business Opportunities or Intellectual Property or other geological,
geophysical, economic, financial or management aspects of the business,
operations, properties or prospects of the Related Parties, whether oral or in
written form in a "Related Parties' Business Records" (as defined in Section 5
below), but shall exclude any information which (i) has become part of the
common knowledge or understanding in the oil and gas industry or otherwise in
the public domain (other than from disclosure by Employee in violation of this
Agreement), or (ii) was rightfully in the possession of Employee, as shown by
Employee's records, prior to the date of this Agreement; provided, however,
that Employee shall provide to the Company copies of all information described
in clause (ii); and provided further that this Section 3 shall not be
applicable to the extent Employee is required to testify in a judicial or
regulatory proceeding pursuant to the order of a judge or administrative law
judge after Employee requests that such Confidential Information be preserved.

         4.      Post Employment Non-Compete Covenant.

         (a) Employee agrees that during the one year period following the
Termination Date, he will not engage or participate in any manner, whether
directly or indirectly through any family member or as an employee, employer,
consultant, agent, principal, partner, more than one percent shareholder,
officer, director, licensor, lender, lessor or in any other individual or
representative capacity, in any business or activity which is in direct
competition with the business of the Related Parties as to leasing, acquiring,
exploring, producing, gathering or marketing hydrocarbons and related products

Employee from:

                 (i) making investments in securities of oil and gas companies
         which are registered on a national stock exchange, if (A) the
         aggregate amount owned by Employee and all family members and
         affiliates does not exceed 5% of such company's outstanding
         securities, and (B) the aggregate amount invested in such investments
         by Employee and all family members and affiliates after the date
         hereof does not exceed $3,000,000; or

                 (ii) maintaining his Existing Personal Investments, if such
         personal investments do not involve any business activity that relates
         to the lease, acquisition, exploration, production, gathering or
         marketing of hydrocarbons and related products other than as permitted
         by Section 2; and

         (b) Employee agrees that during the one year period following the
Termination Date, he will not solicit, entice, persuade or induce, directly or
indirectly, any employee (or person who within the preceding ninety (90) days
was an employee) of any of the Related Parties or any other person who is under
contract with or rendering services to any of the Related Parties, to (i)
terminate his or her employment by, or contractual relationship with, such
person, (ii) refrain from extending or renewing the same (upon the same or new
terms), (iii) refrain from rendering services to or for such person, (iv)
become employed by or to enter into contractual relations with any Persons
other than such person, or (v) enter into a relationship with a competitor of

          5.      Business Records.

         (a)     The Employee agrees to promptly deliver to the Company, upon
termination of his employment by the Related Parties, or at any other time when
the Company so requests, all documents relating to the business of the Related
Parties, including, without limitation: all geological and geophysical reports
and related data such as maps, charts, logs, seismographs, seismic records and
other reports and related data, calculations, summaries, memoranda and opinions
relating to the foregoing, production records, electric logs, core data,
pressure data, lease files, well files and records, land files, abstracts,
title opinions, title or curative matters, contract files, notes, records,
drawings, manuals, correspondence, financial and accounting information,
customer lists, statistical data and compilations, patents, copyrights,
trademarks, trade names, inventions, formulae, methods, processes, agreements,
contracts, manuals or any other documents relating to the business of the
Related Parties, (collectively, the "RELATED PARTIES' BUSINESS RECORDS"), and
all copies thereof and therefrom.

         (b)     The Employee confirms that all of the Related Parties'
Business Records (and all copies thereof and therefrom) which are required to
be delivered to the Company pursuant to this Section constitute the exclusive
property of the Company and the other Related Parties.



                                      4
<PAGE>   5
         (c)     The obligation of confidentiality set forth in Section 3 shall
continue notwithstanding the Employee's delivery of any such documents to the
Company.

         (d)     Notwithstanding the foregoing provisions of this Section 5 or
any other provision of this Agreement, the Employee shall be entitled to retain
any (i) written materials received by the Employee in the capacity as limited
partner of the Partnership, and (ii) written materials which, as shown by the
Employee's records, were in Employee's possession on or prior to the date
hereof, subject to the Company's right to receive a copy of all such materials.

         (e)     The provisions of this Section 5 shall continue in effect
notwithstanding termination of the Employee's employment hereunder for any
reason.

         6.      Miscellaneous.

         (a)     The invalidity or non-enforceability of any provision of this
Agreement in any respect shall not affect the validity or enforceability of
this Agreement in any other respect or of any other provision of this
Agreement. In the event that any provision of this Agreement shall be held
invalid or unenforceable by a court of competent jurisdiction by reason of the
geographic or business scope or the duration thereof, such invalidity or
unenforceability shall attach only to the scope or duration of such provision
and shall not affect or render invalid or unenforceable any other provision of
this Agreement, and, to the fullest extent permitted by law, this Agreement
shall be construed as if the geographic or business scope or the duration of
such provision had been more narrowly drafted so as not to be invalid or
unenforceable.

         (b)     Employee acknowledges that the Partnership's and the Company's
remedy at law for any breach of the provisions of this Agreement is and will be
insufficient and inadequate and that the Partnership and the Company shall be
entitled to equitable relief, including by way of temporary and permanent
injunction, in addition to any remedies the Partnership and the Company may
have at law.

         (c)     The representations and covenants contained in this Agreement
on the part of the Employee will be construed as ancillary to and independent
of any other agreement between the Company and/or the Partnership and the
Employee, and the existence of any claim or cause of action of the Employee
against the Company or any of the other Related Parties or any officer,
director, or shareholder of the Company or any of the other Related Parties,
whether predicated on Employee's employment or otherwise, shall not constitute
a defense to the enforcement by the Company or the Partnership of the covenants
of the Employee contained in this Agreement. In addition, the provisions of
this Agreement shall continue to be binding upon the Employee in accordance
with their terms, notwithstanding the termination of the Employee's employment
for any reason.

         (d)     The parties to this Agreement agree that the limitations
contained in Section 4 with respect to time, geographical area, and scope of
activity are reasonable. However, if any court shall determine that the time,
geographical area, or scope of activity of any restriction contained in Section
4 is unenforceable, it is the intention of the parties that such restrictive
covenant set forth herein shall not thereby be terminated but shall be deemed
amended to the extent required to render it valid and enforceable.




                                      5

         (e)     Any notices or other communications required or permitted to
be sent hereunder shall be in writing and shall be duly given if personally
delivered or sent postage pre-paid by certified or registered mail, return
receipt requested, if to Employee at the address set forth opposite Employee's
name on the signature page hereof, and if to the Company or the Partnership, at
500 West Texas, Suite 500, Midland, Texas 79701. Either party may change his or
its address for the sending of notice to such party by written notice to the
other party sent in accordance with the provisions hereof.

         (f)  This Agreement may not be altered or amended except by a writing,
duly executed by the party against whom such alteration or amendment is sought
to be enforced.

         (g)    This Agreement may be executed in counterparts, each of which
shall be an original and all of which together shall constitute one and the
same instrument.

       IN WITNESS WHEREOF, each of the parties hereto has executed this
Agreement in multiple counterparts as of the day and year first above written.

Employee's duties hereunder. Employee agrees that during the Employment Term
and during the one year period following the date of termination of Employee's

         marketing of hydrocarbons and related products other than as permitted
         by Section 2; and

         (b) Employee agrees that during the one year period following the

termination of his employment by the Related Parties, or at any other time when

Parties, including, without limitation: all geological and geophysical reports
and related data such as maps, charts, logs, seismographs, seismic records and
other reports and related data, calculations, summaries, memoranda and opinions
relating to the foregoing, production records, electric logs, core data,
pressure data, lease files, well files and records, land files, abstracts,

<PAGE>   5
         (b)     Employee confirms that all of the Related Parties' Business
Records (and all copies thereof and therefrom) which are required to be
delivered to the Company pursuant to this Section 5 constitute the exclusive
property of the Company and the other Related Parties.

         (c)     The obligation of confidentiality set forth in Section 3 shall
continue notwithstanding Employee's delivery of any such documents to the
Company.

         (d)     Notwithstanding the foregoing provisions of this Section 5 or
any other provision of this Agreement, Employee shall be entitled to retain any
written materials which, as shown by Employee's records, were in Employee's
possession on or prior to the date hereof, subject to the Company's right to
receive a copy of all such materials.

         (e)     The provisions of this Section 5 shall continue in effect
notwithstanding termination of Employee's employment hereunder for any reason.

         6.      Miscellaneous.

         (a)     The invalidity or non-enforceability of any provision of this
Agreement in any respect shall not affect the validity or enforceability of
this Agreement in any other respect or of any other provision of this
Agreement. In the event that any provision of this Agreement shall be held
invalid or unenforceable by a court of competent jurisdiction by reason of the
geographic or business scope or the duration thereof, such invalidity or
unenforceability shall attach only to the scope or duration of such provision
and shall not affect or render invalid or unenforceable any other provision of
this Agreement, and, to the fullest extent permitted by law, this Agreement
shall be construed as if the geographic or business scope or the duration of
such provision had been more narrowly drafted so as not to be invalid or
unenforceable.

         (b)     Employee acknowledges that the Related Parties' remedies at
law for any breach of the provisions of this Agreement is and will be
insufficient and inadequate and that the Company and the General Partner shall
be entitled to equitable relief, including by way of temporary and permanent
injunction, in addition to any remedies the Company and the General Partner may
have at law.

         (c)     The representations and covenants contained in this Agreement
on the part of Employee will be construed as ancillary to and independent of
any other agreement between the Company and/or the General Partner and
Employee, and the existence of any claim or cause of action of Employee against
the Company or any of the other Related Parties or any officer, director, or
shareholder of the Company or any of the other Related Parties, whether
predicated on Employee's employment or otherwise, shall not constitute a
defense to the enforcement by the Company or the General Partner of the
covenants of Employee contained in this Agreement. In addition, the provisions
of this Agreement shall continue to be binding upon Employee in accordance with
their terms, notwithstanding the termination of Employee's employment for any
reason.

         (d)     The parties to this Agreement agree that the limitations
contained in Section 4 with respect to time, geographical area, and scope of
activity are reasonable. However, if any court shall determine that the time,
geographical area, or scope of activity of any restriction contained





                                       5
<PAGE>   6
in Section 4 is unenforceable, it is the intention of the parties that such
restrictive covenant set forth herein shall not thereby be terminated but shall
be deemed amended to the extent required to render it valid and enforceable.

         (e)     Any notices or other communications required or permitted to
be sent hereunder shall be in writing and shall be duly given if personally
delivered or sent postage pre-paid by certified or registered mail, return
receipt requested, if to Employee at the address set forth opposite Employee's
name on the signature page hereof, and if to the Company or the General
Partner, at 500 West Texas, Suite 500, Midland, Texas 79701. Either party may
change his or its address for the sending of notice to such party by written
notice to the other party sent in accordance with the provisions hereof.

         (f)  This Agreement may not be altered or amended except by a writing,
duly executed by the party against whom such alteration or amendment is sought
to be enforced.

       (g)    This Agreement may be executed in counterparts, each of which
shall be an original and all of which together shall constitute one and the
same instrument.

                 (b)      Subject to the provisions hereof, the Committee shall
         have full and exclusive power and authority to administer this Plan
         and to take all actions that are specifically contemplated hereby or
         are necessary or appropriate in connection with the administration
         hereof. The Committee shall also have full and exclusive power to
         interpret this Plan and to adopt such rules, regulations and
         guidelines for carrying out this Plan as it may deem necessary or
         proper, all of which powers shall be exercised in the best interests

         Committee may correct any defect or supply any omission or reconcile
         any inconsistency in this Plan or in any Award in the manner and to

         Plan purposes.  Any decision of the Committee in the interpretation

         to whom the Committee has delegated authority in accordance with the
         provisions of paragraph 7 of this Plan shall be liable for anything
         done by him or her, by any member of the Committee or by any officer
         of the Company in connection with the performance of any duties under
         this Plan, except for his or her own willful misconduct or as
         expressly provided by statute.

                 7.       Delegation of Authority. The Committee may delegate
to the Chief Executive Officer and to other senior officers of the Company its
duties under this Plan pursuant to such conditions or limitations as the
Committee may establish.

                 8.       Awards. The Committee shall determine the type or
types of Awards to be made under this Plan and shall designate from time to

and limitations as shall be determined by the Committee in its sole discretion
and shall be signed by the Participant to whom the Award is made and by an
Authorized Officer for and on behalf of the Company. Awards may consist of
those listed in this paragraph 8 hereof and may be granted singly, in
combination or in tandem. Awards may also be made in combination or in tandem
with, in replacement of, or as alternatives to, grants or rights under this
Plan or any other employee plan of the Company or any of its Subsidiaries,
including the plan of any acquired entity. An Award may provide for the grant
or issuance of additional, replacement or alternative Awards upon the
occurrence of specified events, including

Award may be subject to conditions established by the Committee, which may
include, but are not limited to, continuous service with the Company and its
Subsidiaries, achievement of specific business objectives, increases in
specified indices, attainment of specified growth rates and other comparable
measurements of performance. Upon the termination of employment by a
Participant, any unexercised, deferred, unvested or unpaid Awards shall be
treated as set forth in the applicable Award Agreement.

                 (a)      Stock Option. An Award may be in the form of an
         Option. An Option awarded pursuant to this Plan may consist of an
         Incentive Option or a Nonqualified Option. The price at which shares
         of Common Stock may be purchased upon the exercise of any Incentive
         Option shall be not less than the Fair Market Value of the Common
         Stock on the date of grant. The price at which shares of Common Stock
         may be purchased upon the exercise of a Nonqualified Option shall be
         not less than the greater of 50 percent of the Fair Market Value of
         the Common Stock on the date of grant or its par value. The maximum
         number of shares of Common Stock with respect to which any Option may
         be granted to an Employee hereunder is the number of shares available
         for Awards, pursuant to paragraph 5 hereof, at the time such Option is
         granted. Subject to the foregoing provisions, the terms, conditions
         and limitations applicable to any Options awarded pursuant to this
         Plan, including the term of any Options and the date or dates upon
         which they become exercisable, shall be determined by the Committee.

                 (b)      Stock Appreciation Right. An Award may be in the form
         of an SAR. The terms, conditions and limitations applicable to any
         SARs awarded pursuant to this Plan, including the term of any SARs and
         the date or dates upon which they become exercisable, shall be
         determined by the Committee.

                 (c)      Stock Award. An Award may be in the form of a Stock
         Award. The terms, conditions and limitations applicable to any Stock
         Awards granted pursuant to this Plan shall be determined by the
         Committee.

                 (d)      Cash Award. An Award may be in the form of a Cash
         Award. The terms, conditions and limitations applicable to any Cash
         Awards granted pursuant to this Plan shall be determined by the
         Committee.

                 (e)      Performance Award. Without limiting the type or
         number of Awards that may be made under the other provisions of this
         Plan, an Award may be in the form of a Performance Award. A
         Performance Award shall be paid, vested or otherwise deliverable
         solely on account of the attainment of one or more pre-established,
         objective Performance Goals established by the Committee.

                 9.       Payment of Awards.

                 (a)      General. Payment of Awards may be made in the form of
         cash or Common Stock, or a combination thereof, and may include such
         restrictions as the Committee shall determine, including, in the case
         of Common Stock, restrictions on





                                      -5-
<PAGE>   6
         transfer and forfeiture provisions. If payment of an Award is made in
         the form of Restricted Stock, the Award Agreement relating to such
         shares shall specify whether they are to be issued at the beginning or
         end of the Restriction Period. In the event that shares of Restricted
         Stock are to be issued at the beginning of the Restriction Period, the
         certificates evidencing such shares (to the extent that such shares
         are so evidenced) shall contain appropriate legends and restrictions
         that describe the terms and conditions of the restrictions applicable
         thereto. In the event that shares of Restricted Stock are to be issued
         at the end of the Restriction Period, the right to receive such shares
         shall be evidenced by book entry registration or in such other manner
         as the Committee may determine.

                 (b)      Deferral. With the approval of the Committee,
         payments in respect of Awards may be deferred, either in the form of
         installments or a future lump-sum payment. The Committee may permit
         selected Participants to elect to defer payments of some or all types
         of Awards in accordance with procedures established by the Committee.
         Any deferred payment of an Award, whether elected by the Participant
         or specified by the Award Agreement or by the Committee, may be
         forfeited if and to the extent that the Award Agreement so provides.

                 (c)      Dividends and Interest. Rights to dividends or
         Dividend Equivalents may be extended to and made part of any Award
         consisting of shares of Common Stock or units denominated in shares of
         Common Stock, subject to such terms, conditions and restrictions as
         the Committee may establish. The Committee may also establish rules
         and procedures for the crediting of interest on deferred cash payments
         and Dividend Equivalents for Awards consisting of shares of Common
         Stock or units denominated in shares of Common Stock.

                 (d)      Substitution of Awards. At the discretion of the
         Committee, a Participant may be offered an election to substitute an
         Award for another Award or Awards of the same or different type.

                 10.      Stock Option Exercise. The price at which shares of
Common Stock may be purchased under an Option shall be paid in full at the time
of exercise in cash or, if elected by the optionee, the optionee may purchase
such shares by means of tendering Common Stock or surrendering another Award,
including Restricted Stock, valued at Fair Market Value on the date of
exercise, or any combination thereof. The Committee shall determine acceptable
methods for Participants to tender Common Stock or other Awards. The Committee
may provide for procedures to permit the exercise or purchase of such Awards by
use of the proceeds to be received from the sale of Common Stock issuable
pursuant to an Award. Unless otherwise provided in the applicable Award
Agreement, in the event shares of Restricted Stock are tendered as
consideration for the exercise of an Option, a number of the shares issued upon
the exercise of the Option, equal to the number of shares of Restricted Stock
used as consideration therefor, shall be subject to the same restrictions as
the Restricted Stock so submitted as well as any additional restrictions that
may be imposed by the Committee.

                 11.      Tax Withholding. The Company shall have the right to
deduct applicable taxes from any Award payment and withhold, at the time of
delivery or vesting of cash or shares of Common Stock under this Plan, an
appropriate amount of cash or number of shares of Common Stock or a combination
thereof for payment of taxes required by law or to take such other action as
may be necessary in the opinion of the Company to satisfy all obligations for
withholding of such taxes. The Committee may also permit withholding to be
satisfied by the transfer to the Company of shares of Common Stock theretofore
owned by the holder of the Award with respect to which withholding is required.
If shares of Common Stock are used to satisfy tax withholding, such shares
shall be valued based on the Fair Market Value when the tax withholding is
required to be made. The Committee may provide for loans, on either a
short-term or demand basis, from the Company to a Participant to permit the
payment of taxes required by law.

                 12.      Amendment, Modification, Suspension or Termination.
The Board may amend, modify, suspend or terminate this Plan for the purpose of
meeting or addressing any changes in legal requirements or for any other
purpose permitted by law, except that no amendment or alteration that would
adversely affect the rights of any Participant under any Award previously
granted to such Participant shall be made without the consent of such
Participant.

                 13.      Assignability. The Committee may prescribe and
include in applicable Award Agreements restrictions on transfer. Any attempted
assignment of an Award or any other benefit under this Plan in violation of
this paragraph 13 shall be null and void.

                 14.      Adjustments.

                 (a)      The existence of outstanding Awards shall not affect
         in any manner the right or power of the Company or its stockholders to
         make or authorize any or all adjustments, recapitalizations,
         reorganizations or other changes in the capital stock of the Company
         or its business or any merger or consolidation of the Company, or any
         issue of bonds, debentures, preferred or prior preference stock
         (whether or not such issue is prior to, on a parity with or junior to
         the Common Stock) or the dissolution or liquidation of the Company, or
         any sale or transfer of all or any part of its assets or business, or
         any other corporate act or proceeding of any kind, whether or not of a
         character similar to that of the acts or proceedings enumerated above.

                 (b)      In the event of any subdivision or consolidation of
         outstanding shares of Common Stock, declaration of a dividend payable
         in shares of Common Stock or other stock split, then (i) the number of
         shares of Common Stock reserved under this Plan, (ii) the number of
         shares of Common Stock covered by outstanding Awards in the form of
         Common Stock or units denominated in Common Stock, (iii) the exercise
         or other price in respect of such Awards and (iv) the appropriate Fair
         Market Value and other price determinations for such Awards shall each
         be proportionately adjusted by the Board to reflect such transaction.
         In the event of any other recapitalization or capital reorganization
         of the Company, any consolidation or merger of the Company with
         another corporation or entity, the adoption by the Company of any plan
         of exchange





                                      -7-
<PAGE>   8
         affecting the Common Stock or any distribution to holders of Common
         Stock of securities or property (other than normal cash dividends or
         dividends payable in Common Stock), the Board shall make appropriate
         adjustments to (i) the number of shares of Common Stock covered by
         Awards in the form of Common Stock or units denominated in Common
         Stock, (ii) the exercise or other price in respect of such Awards and
         (iii) the appropriate Fair Market Value and other price determinations
         for such Awards to give effect to such transaction shall each be
         proportionately adjusted by the Board to reflect such transaction;
         provided that such adjustments shall only be such as are necessary to
         maintain the proportionate interest of the holders of the Awards and
         preserve, without exceeding, the value of such Awards. In the event of
         a corporate merger, consolidation, acquisition of property or stock,
         separation, reorganization or liquidation, the Board shall be
         authorized to issue or assume Awards by means of substitution of new
         Awards, as appropriate, for previously issued Awards or to assume
         previously issued Awards as part of such adjustment.

                 15.      Restrictions. No Common Stock or other form of
payment shall be issued with respect to any Award unless the Company shall be
satisfied based on the advice of its counsel that such issuance will be in
compliance with applicable federal and state securities laws. Certificates
evidencing shares of Common Stock delivered under this Plan (to the extent that
such shares are so evidenced) may be subject to such stop transfer orders and
other restrictions as the Committee may deem advisable under the rules,
regulations and other requirements of the Securities and Exchange Commission,
any securities exchange or transaction reporting system upon which the Common
Stock is then listed or to which it is admitted for quotation and any
applicable federal or state securities law. The Committee may cause a legend or
legends to be placed upon such certificates (if any) to make appropriate
reference to such restrictions.

                 16.      Unfunded Plan. Insofar as it provides for Awards of
cash, Common Stock or rights thereto, this Plan shall be unfunded. Although
bookkeeping accounts may be established with respect to Participants who are
entitled to cash, Common Stock or rights thereto under this Plan, any such
accounts shall be used merely as a bookkeeping convenience. The Company shall
not be required to segregate any assets that may at any time be represented by
cash, Common Stock or rights thereto, nor shall this Plan be construed as
providing for such segregation, nor shall the Company, the Board or the
Committee be deemed to be a trustee of any cash, Common Stock or rights thereto
to be granted under this Plan. Any liability or obligation of the Company to
any Participant with respect to an Award of cash, Common Stock or rights
thereto under this Plan shall be based solely upon any contractual obligations
that may be created by this Plan and any Award Agreement, and no such liability
or obligation of the Company shall be deemed to be secured by any pledge or
other encumbrance on any property of the Company. Neither the Company nor the
Board nor the Committee shall be required to give any security or bond for the
performance of any obligation that may be created by this Plan.

                 17.      Governing Law. This Plan and all determinations made
and actions taken pursuant hereto, to the extent not otherwise governed by
mandatory provisions of the Code or the securities laws of the United States,
shall be governed by and construed in accordance with the laws of the State of
Delaware.

                 18.      Effectiveness. This Plan shall be effective as of
October 1, 1996, (the "Effective Date"), the date on which it was approved by
the Board of Directors of the Company. Notwithstanding the foregoing, the
ability of the Company to issue any Incentive Options under this Plan is
expressly conditioned upon the approval of the Plan by the holders of a
majority of shares of Common Stock on or before October 1, 1997. If the
Stockholders of the Company should fail to so approve this Plan prior to such
date, the Company's ability to issue Incentive Options under this Plan shall
terminate and cease to be of any further force or effect and any and all grants
of Incentive Options hereunder shall be null and void.

         subject to the conditions set out in Article III, the Company may
         obtain Borrowings of Loans, repay or prepay such Loans, and reborrow
         such Loans.  Any portion of each Lender's Commitment not utilized on
         or before the Maturity Date shall be permanently cancelled.

                 (b)      Types of Loans.  The Loans made pursuant hereto by
         each Lender shall, at the option of the Company, be either Base Rate
         Loans or Eurodollar Loans and may be continued or converted pursuant
         to Section 2.11, provided that, except as otherwise specifically
         provided herein, all Loans made pursuant to the same Borrowing shall
         be of the same Type.

                 (c)      Commitments.  Each Lender's Credit Exposure shall not
         exceed at any one time the amount set forth opposite such Lender's
         name on Annex I under the caption "Commitment" (as the same may be
         reduced pursuant to Section 2.09 or otherwise from time to time
         modified pursuant to Section 8.07(b), its "Commitment," and
         collectively for all Lenders, the "Commitments").

                 (d)      Amounts of Borrowings, etc.  The aggregate principal
         amount of each Borrowing (i) of Eurodollar Loans shall be not less
         than $3,000,000 and shall be in an integral multiple of $1,000,000,
         and (ii) of Base Rate Loans shall be not less than $1,000,000 and
         shall be in an integral multiple of $100,000, except that any
         Borrowing of Loans that are Base Rate Loans may be in the aggregate
         amount of the unused Maximum Loan Available Amount in effect at such
         time.  Borrowings of more than one Type may be outstanding at the same
         time; provided, however, that the Company shall not be entitled to
         request any Borrowing that, if made, would result in an aggregate of
         more than five separate Borrowings of Eurodollar Loans being
         outstanding at any one time.  For purposes of the foregoing,
         Borrowings having different Interest Periods, regardless of whether
         they commence on the same date, shall be considered separate
         Borrowings.

         Section 2.02     Borrowing Requests.

                 (a)      Borrowing Requests.  Whenever the Company desires to
         make a Borrowing hereunder, it shall give Advance Notice in the form
         of a Borrowing Request, specifying, subject to the provisions hereof,
         (i) the aggregate principal amount of the Loans to be made pursuant to
         such Borrowing, (ii) the date of Borrowing (which shall be a Business
         Day), (iii) whether the Loans being made pursuant to such Borrowing
         are to be Base Rate Loans or Eurodollar Loans, and (iv) in the case of
         Eurodollar Loans, the Interest Period to be applicable thereto.

                 (b)      Notice by Administrative Agent.  The Administrative
         Agent shall promptly give each Lender telecopy or telephonic notice
         (and, in the case of telephonic notices, confirmed by telecopy or
         otherwise in writing) of the proposed Borrowing, of such Lender's
         Percentage Share thereof and of the other matters covered by the
         Advance Notice.  Without in any way limiting the Company's obligation
         to confirm in writing any telephonic notice, the Administrative Agent
         may act without liability upon the basis of telephonic notice believed
         by the Administrative Agent in good faith to be from the Company prior
         to receipt of written confirmation.  In each such case, the Company
         hereby waives the right to dispute the Administrative Agent's record
         of the terms of such telephonic notice, absent manifest error.

         Section 2.03     Letters of Credit.

                 (a)      Issuance of Letters of Credit.  Subject to the terms
         and conditions hereof, the Issuing Bank agrees to issue and the
         Company shall have the right, in addition to Loans provided for in
         Section 2.01, to utilize the Commitments from time to time prior to
         the Maturity Date by





                                     -17-
<PAGE>   23
         obtaining the issuance of Standby Letters of Credit for the account of
         any Loan Party by the Issuing Bank if the Company shall so request in
         the notice referred to in Section 2.03(b)(i) (such letters of credit
         being collectively referred to as the "Letters of Credit"); provided,
         however, that the aggregate amount of all Letters of Credit at any one
         time outstanding shall not exceed the lesser of (A) $15,000,000, or
         (B) the Maximum Available Amount in effect at such time, minus the
         aggregate principal amount of all Loans then outstanding.  The Letters
         of Credit shall be denominated in Dollars and may be issued to support
         the obligations of the Company or any of its Subsidiaries.  Upon the
         date of the issuance of a Letter of Credit, the Issuing Bank shall be
         deemed, without further action by any party hereto, to have sold to
         each Lender, and each Lender shall be deemed, without further action
         by any party hereto, to have purchased from the Issuing Bank, a
         participation, to the extent of such Lender's Percentage Share, in
         such Letter of Credit and the related LC Liabilities.  No Letter of
         Credit issued pursuant to this Agreement shall have an expiry date
         later than one year from its date of issuance; provided, however, any
         Letter of Credit may give the beneficiary thereof either the right to
         draw on such Letter of Credit upon its expiry date or the right to
         automatically extend the expiry date thereof for periods of up to one
         year per extension; provided, further, however, no Letter of Credit
         issued pursuant to this Agreement shall ever have an expiry date
         beyond the Maturity Date and no such extension shall extend an expiry
         date beyond the Maturity Date.  The Company and the Lenders agree
         that, as of the Effective Date, the Outstanding Letters of Credit
         shall be deemed for all purposes of this Agreement to be Letters of
         Credit issued under and pursuant to the terms of this Agreement.

                 (b)      Additional Letter of Credit Provisions.  The
         following additional provisions shall apply to each Letter of Credit:

                 (i)  The Company shall give the Administrative Agent and the
         Issuing Bank at least five Business Days' prior notice (effective upon
         receipt), or in each case, such shorter period as may be agreed to by
         the Administrative Agent and the Issuing Bank, specifying the date
         such Letter of Credit is to be issued (which shall be a Business Day)
         by the Issuing Bank and describing (A) the face amount of the Letter
         of Credit, (B) the expiry date of the Letter of Credit, (C) the name
         and address of the beneficiary, (D) information concerning the
         transaction proposed to be supported by such Letter of Credit as the
         Administrative Agent or the Issuing Bank may reasonably request, (E)
         such other information and documents relating to the Letter of Credit
         as the Administrative Agent or the Issuing Bank may reasonably
         request, and (F) a precise description of documents and the verbatim
         text of any certificate to be presented by the beneficiary, which, if
         presented on or prior to the expiry date of the Letter of Credit,
         would require the Issuing Bank to make payment under the Letter of
         Credit; provided that the Issuing Bank, in its reasonable judgment,
         may require changes in such documents and certificates; and provided
         further that the Issuing Bank shall not be required to issue any
         Letter of Credit that on its terms requires payment thereunder prior
         to the next Business Day following receipt by the Issuing Bank of such
         documents and certificates.  Each such notice shall be accompanied by
         the Issuing Bank's Application (which shall be deemed to be subject to
         the last sentence of clause (v) below, whether or not expressly stated
         in such Application) and by a certificate executed by a Responsible
         Officer setting forth calculations evidencing availability for such
         Letter of Credit pursuant to Section 2.03(b)(ii) and stating that all
         conditions precedent to such issuance have been satisfied.  Each
         Letter of Credit shall, to the extent not inconsistent with the
         express terms hereof or the applicable Application, be subject to the
         Uniform Customs and Practice for Documentary Credits (1993 Revision),
         International Chamber of Commerce Publication No. 500 (together with



                                     -18-

<PAGE>   24
         any subsequent revisions thereof approved by a Congress of the
         International Chamber of Commerce and adhered to by the Issuing Bank,
         the "UCP"), and shall, as to matters not governed by the UCP, be
         governed by, and construed and interpreted in accordance with, the
         laws of the State of New York.

                 (ii)  No Letter of Credit may be issued if after giving effect
         thereto the Aggregate Credit Exposure would exceed the Maximum
         Available Amount.  On each day during the period commencing with the
         issuance of any Letter of Credit and until such Letter of Credit shall
         have expired or have been terminated, the Commitment of each Lender
         shall be deemed to be utilized for all purposes hereof in an amount
         equal to such Lender's Percentage Share of the amount of the LC
         Liabilities related to such Letter of Credit.

                 (iii)  Upon receipt from the beneficiary of any Letter of
         Credit of any demand (by draft or otherwise) for payment thereunder
         (each such payment by the Issuing Bank is herein called a "drawing"),
         the Issuing Bank shall promptly notify the Company and the
         Administrative Agent of such demand (provided that the failure of the
         Issuing Bank to give such notice shall not affect the Reimbursement
         Obligations of the Company hereunder) and the Company shall
         immediately, and in any event no later than 12:00 p.m. (New York time)
         on the date of such drawing, reimburse the Administrative Agent for
         the account of the Issuing Bank for the amount of such drawing,
         without presentment, demand, protest or other formalities of any kind
         in an amount, in same day funds, equal to the amount of such drawing.
         Unless prior to 12:00 p.m. (New York time) on the date of such
         drawing, the Company shall have either (i) notified the Issuing Bank
         and the Administrative Agent that the Company will on such date and by
         12:00 p.m. (New York time) reimburse the Administrative Agent for the
         account of the Issuing Bank for the amount of such drawing with funds
         other than the proceeds of a Loan (in which case the Company's
         obligation to make such reimbursement by such date and time shall be
         absolute and unconditional) or (ii) delivered to the Administrative
         Agent a Borrowing Request for Loans (which shall be Base Rate Loans
         unless there is sufficient Advance Notice to permit the Company to
         elect Eurodollar Loans) in an amount equal to such drawing, the
         Company will be deemed to have given a Borrowing Request to the
         Administrative Agent requesting that the Lenders make Loans which
         shall be Base Rate Loans on the date on which such drawing is honored
         in an amount equal to the amount of such drawing.  Such Loans shall be
         subject to satisfaction of the conditions in Article III and to
         existence of Maximum Loan Available Amount (after giving effect to the
         reduction of the LC Liabilities by virtue of such Loan).  Subject to
         the preceding sentence, if so requested by the Administrative Agent,
         the Lenders shall, on the date of such drawing, make such Loans in an
         amount equal to such Lender's Percentage Share of such drawing, the
         proceeds of which shall be applied directly by the Administrative
         Agent to reimburse the Issuing Bank for the amount of such drawing.

                 (iv)  If the Company fails to reimburse the Issuing Bank as
         provided in clause (iii) above (because of the Company's inability to
         receive Loans due to a failure to satisfy the conditions of Article
         III or for any other reason), the Issuing Bank shall promptly notify
         the Administrative Agent and the Administrative Agent shall notify
         each Lender of the unreimbursed amount of such drawing and of such
         Lender's respective participation therein based on such Lender's
         Percentage Share.  Each Lender will pay to the Administrative Agent
         for the account of the Issuing Bank on the date of such notice an
         amount equal to such Lender's Percentage Share of such unreimbursed
         drawing on such date (or, if such notice is made after 12:00 p.m., New
         York time, on the next




                                     -19-

         succeeding Business Day).  If any Lender fails to make available to
         the Issuing Bank the amount of such Lender's participation in such
         Letter of Credit as provided in this clause (iv), the Issuing Bank
         shall be entitled to recover such amount on demand from such Lender
         together with interest at the Federal Funds Rate for one Business Day
         and thereafter at the Base Rate.  Nothing in this clause (iv) shall be
         deemed to prejudice the right of any Lender to recover from the
         Issuing Bank any amounts made available by such Lender to the Issuing
         Bank pursuant to this clause (iv) if it is determined by a court of
         competent jurisdiction that the payment with respect to a Letter of
         Credit by the Issuing Bank was wrongful and such wrongful payment was
         the result of gross negligence or willful misconduct on the part of
         the Issuing Bank.  The Issuing Bank shall pay to the Administrative
         Agent, whereupon the Administrative Agent shall forward to each Lender
         such Lender's Percentage Share of all amounts received from the
         Company for payment, in whole or in part, of the Reimbursement
         Obligation in respect of any Letter of Credit, but only to the extent
         such Lender has made payment to the Issuing Bank in respect of such
         Letter of Credit pursuant to this clause (iv).

                 (v)  The issuance by the Issuing Bank of each Letter of Credit
         shall, in addition to the conditions precedent set forth in Article
         III, be subject to the conditions precedent that such Letter of Credit
         shall be in such form and contain such terms as shall be reasonably
         satisfactory to the Issuing Bank, and that the Company shall have
         executed and delivered such other instruments and agreements relating
         to such Letter of Credit as the Issuing Bank shall have reasonably
         requested and that are not inconsistent with the terms of this
         Agreement including the Issuing Bank's Application therefor.  In the
         event of a conflict between the terms of this Agreement and the terms
         of any Application, the terms of this Agreement shall control.

                 (vi)  AS BETWEEN THE COMPANY AND THE ISSUING BANK, THE COMPANY
         ASSUMES ALL RISKS OF THE ACTS AND OMISSIONS OF OR MISUSE OF THE
         LETTERS OF CREDIT ISSUED BY THE ISSUING BANK BY THE RESPECTIVE
         BENEFICIARIES OF SUCH LETTERS OF CREDIT.  IN FURTHERANCE AND NOT IN
         LIMITATION OF THE FOREGOING, THE ISSUING BANK SHALL NOT BE RESPONSIBLE
         (EXCEPT TO THE EXTENT ARISING FROM THE ISSUING BANK'S GROSS NEGLIGENCE
         OR WILLFUL MISCONDUCT): (A) FOR THE FORM, VALIDITY, SUFFICIENCY,
         ACCURACY, GENUINENESS OR LEGAL EFFECT OF ANY DOCUMENT SUBMITTED BY ANY
         PERSON IN CONNECTION WITH THE APPLICATION FOR OR ISSUANCE OF SUCH
         LETTERS OF CREDIT, EVEN IF IT SHOULD IN FACT PROVE TO BE IN ANY OR ALL
         RESPECTS INVALID, INSUFFICIENT, INACCURATE, FRAUDULENT OR FORGED;
         PROVIDED, HOWEVER, ISSUING BANK SHALL REMAIN RESPONSIBLE AS AN ISSUER
         OF A LETTER OF CREDIT FOR ASSURING THAT PAYMENT ON A LETTER OF CREDIT
         IS MADE ONLY ON DOCUMENTS WHICH ON THEIR FACE COMPLY WITH THE
         REQUIREMENTS OF THE LETTER OF CREDIT; (B) FOR THE VALIDITY OR
         SUFFICIENCY OF ANY INSTRUMENT TRANSFERRING OR ASSIGNING OR PURPORTING
         TO TRANSFER OR ASSIGN ANY SUCH LETTER OF CREDIT OR THE RIGHTS OR
         BENEFITS THEREUNDER OR PROCEEDS THEREOF, IN WHOLE OR IN PART, WHICH
         MAY PROVE TO BE INVALID OR INEFFECTIVE FOR ANY REASON; (C) FOR FAILURE
         OF THE BENEFICIARY OF ANY SUCH LETTER OF CREDIT TO COMPLY FULLY WITH
         CONDITIONS REQUIRED IN ORDER TO DRAW UPON SUCH LETTER OF CREDIT, TO
         THE EXTENT SUCH FAILURE IS NOT THE RESULT OF GROSS NEGLIGENCE OR
         WILLFUL MISCONDUCT OF THE ISSUING BANK; (D) FOR ERRORS, OMISSIONS,
         INTERRUPTIONS OR DELAYS IN TRANSMISSION OR DELIVERY OF ANY MESSAGES,
         BY MAIL, CABLE, TELEGRAPH, TELEX OR OTHERWISE, WHETHER OR NOT THEY ARE
         IN CIPHER; (E) FOR ERRORS IN INTERPRETATION OF TECHNICAL TERMS; (F)
         FOR ANY LOSS OR DELAY IN THE TRANSMISSION OR OTHERWISE





                                     -20-
<PAGE>   26
         OF ANY DOCUMENT REQUIRED IN ORDER TO MAKE A DRAWING UNDER ANY SUCH
         LETTER OF CREDIT OR OF THE PROCEEDS THEREOF; (G) FOR THE
         MISAPPLICATION BY THE BENEFICIARY OF ANY SUCH LETTER OF CREDIT OF THE
         PROCEEDS OF ANY DRAWING UNDER SUCH LETTER OF CREDIT; AND (H) FOR ANY
         CONSEQUENCES ARISING FROM CAUSES BEYOND THE CONTROL OF THE ISSUING
         BANK, INCLUDING, WITHOUT LIMITATION, THE ACTIONS OF ANY GOVERNMENTAL
         AUTHORITY.  NONE OF THE ABOVE SHALL AFFECT, IMPAIR, OR PREVENT THE
         VESTING OF ANY OF THE ISSUING BANK'S RIGHTS OR POWERS HEREUNDER.
         NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS CLAUSE
         (VI), THE COMPANY SHALL HAVE NO OBLIGATION TO INDEMNIFY THE ISSUING
         BANK IN RESPECT OF ANY LIABILITY INCURRED BY THE ISSUING BANK TO THE
         EXTENT ARISING OUT OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF
         THE ISSUING BANK.

                 (vii)  The Issuing Bank will send to the Company and the
         Administrative Agent immediately upon issuance of any Letter of
         Credit, or an amendment thereto, a true and complete copy of such
         Letter of Credit, or such amendment thereto.  Upon issuance of any
         Letter of Credit or an amendment thereto, the Administrative Agent
         shall promptly notify each Lender of the terms of such Letter of
         Credit or amendment thereto, of the Issuing Bank for such Letter of
         Credit or amendment thereto, and of such Lender's Percentage Share of
         the amount of such Letter of Credit or amendment thereto, and the
         Administrative Agent shall provide to each Lender a copy of such
         Letter of Credit or such amendment thereto.  Upon cancellation or
         termination of any Letter of Credit, the Issuing Bank shall promptly
         notify the Administrative Agent and the Company, and the
         Administrative Agent will then promptly notify each Lender, of such
         cancellation or termination.

                 (viii) The obligation of the Company to reimburse the Issuing
         Bank for Reimbursement Obligations with regard to the Letters of
         Credit issued by it and the obligations of Lenders under clause (iv)
         shall be unconditional and irrevocable and shall be paid strictly in
         accordance with the terms of this Agreement and under all
         circumstances including, without limitation, the following
         circumstances:

                          (A)     any lack of validity or enforceability of 
                 any Letter of Credit;

                          (B)     the existence of any claim, set-off, defense
                 or other right that the Company may have at any time against a
                 beneficiary or any assignee or transferee of any Letter of
                 Credit (or any Persons for whom any such assignee or
                 transferee may be acting), any Lender or any other Person,
                 whether in connection with this Agreement, the transactions
                 contemplated herein or any unrelated transaction (including
                 any underlying transaction between the Company or one of its
                 Subsidiaries and the beneficiary for which the Letter of
                 Credit was procured) other than a defense based on the gross
                 negligence or willful misconduct of the Issuing Bank;

                          (C)     any draft, demand, certificate or any other
                 document presented under any Letter of Credit is proved to be
                 forged, fraudulent, invalid or insufficient in any respect or
                 any statement therein is untrue or inaccurate in any respect;

                          (D)     any adverse change in the condition 
                 (financial or otherwise) of the Company;





                                     -21-
<PAGE>   27
                          (E)     any breach of this Agreement or any other
                 Financing Document by the Company, Administrative Agent or any
                 Lender (other than the Issuing Bank);

                          (F)     any other circumstance or happening
                 whatsoever which is similar to any of the foregoing; provided
                 that such other occurrence or happening is not the result of
                 the gross negligence or willful misconduct of the Issuing
                 Bank; or

                          (G)     the fact that a Default shall have occurred 
                 and be continuing.

                 (ix)     Whenever Cover has been provided for any Letter of
         Credit, the Administrative Agent shall continue to hold funds for such
         Letter of Credit in its collateral account for so long as the event or
         condition requiring such Cover continues, provided that (A) so long as
         no Default has occurred which is continuing, the Administrative Agent
         shall release to the Company all of such funds whenever such event or
         condition ceases to exist or whenever such Letter of Credit has
         expired or terminated and all Reimbursement Obligations, if any, with
         respect thereto have been fully satisfied, and (B) so long as no
         Default has occurred which is continuing, the Administrative Agent
         shall release to the Company any excess funds if the LC Liabilities
         with respect to such Letter of Credit decrease and the funds held in
         such deposit account therefore exceed such LC Liabilities.

         Section 2.04     Disbursement of Funds.

                 (a)      Availability.  No later than 12:00 p.m. (New York
         time) on the date of each Borrowing, each Lender will make available
         to the Administrative Agent such Lender's Percentage Share of the
         amount (if any) by which the principal amount of the Borrowing
         requested to be made on such date exceeds the principal amount of
         Loans (if any) maturing or Reimbursement Obligations (if any) due and
         owing on such date, in Dollars and in immediately available funds at
         the Payment Office.  The Administrative Agent will make available to
         the Company at the Payment Office the aggregate of the amounts (if
         any) so made available by the Lenders by depositing such amounts, in
         immediately available funds, to an account of the Company at the
         Administrative Agent designated by the Company for such purpose.  To
         the extent that Loans mature or Reimbursement Obligations are due and
         owing on the date of a requested Borrowing of Loans, the Lenders shall
         apply the proceeds of the Loans then being made, to the extent
         thereof, to the repayment of such maturing Loans or Reimbursement
         Obligations, such Loans and repayments intended to be a
         contemporaneous exchange.

                 (b)      Funds to the Administrative Agent.  Unless the
         Administrative Agent shall have been notified by any Lender prior to
         the date of a Borrowing that such Lender does not intend to make
         available to the Administrative Agent such Lender's Percentage Share
         of the Borrowing to be made on such date, the Administrative Agent may
         assume that such Lender has made such amount available to the
         Administrative Agent on such date, and the Administrative Agent may
         make available to the Company a corresponding amount.  If such
         corresponding amount is not in fact made available to the
         Administrative Agent by such Lender on the date of a Borrowing, the
         Administrative Agent shall be entitled to recover such corresponding
         amount on demand from such Lender together with interest at the
         Federal Funds Rate.  If such Lender does not pay such corresponding
         amount forthwith upon the Administrative Agent's demand therefor, the
         Administrative Agent shall promptly notify the Company, and the
         Company shall immediately





                                     -22-
<PAGE>   28
         pay such corresponding amount to the Administrative Agent together
         with interest at the rate specified for the Borrowing which includes
         such amount paid.  Nothing in this Section shall be deemed to relieve
         any Lender from its obligation to fulfill its Commitment hereunder or
         to prejudice any rights which the Company may have against any Lender
         as a result of any default by such Lender hereunder.

                 (c)      Lenders' Responsibilities.  No Lender shall be
         responsible for any default by any other Lender in its obligation to
         make Loans hereunder, and each Lender shall be obligated to make the
         Loans provided to be made by it hereunder, regardless of the failure
         of any other Lender to fulfill its Commitment hereunder.

         Section 2.05     Notes.  The Company's obligation to pay the principal
of, and interest on, the Loans made by each Lender shall be further evidenced
by the Company's issuance, execution and delivery of a Note payable to the
order of each such Lender in the amount of such Lender's Commitment and shall
be dated as of the date of issuance of such Note.  The principal amount of each
Note shall be payable on or before the Maturity Date.  Each Lender's Note
represents, in part, a renewal, rearrangement and modification of the portion
of the outstanding principal balance owing under the Prior Notes assigned to
such Lender pursuant to the Assignment.

         Section 2.06     Interest.  In all cases subject to Section 8.13:

                 (a)      Base Rate Loans.  Subject to Section 2.06(c), the
         Company agrees to pay interest in respect of the unpaid principal
         amount of each Base Rate Loan from the date thereof until payment in
         full thereof at a rate per annum which shall be, for any day, equal to
         the sum of the Applicable Margin plus the Base Rate in effect on such
         day, but in no event to exceed the Highest Lawful Rate.  The term
         "Base Rate" means the higher of (i) the Prime Rate in effect on such
         day or (ii) one-half of one percent ( 1/2%) plus the Federal Funds
         Rate in effect for such day (rounded upwards, if necessary, to the
         nearest 1/16th of 1%), but in no event to exceed the Highest Lawful
         Rate.  For purposes of this Agreement, any change in the Base Rate due
         to a change in the Federal Funds Rate or the Prime Rate shall be
         effective on the effective date of such change in the Federal Funds
         Rate or the Prime Rate, as the case may be.  If for any reason the
         Administrative Agent shall have determined (which determination shall
         be conclusive and binding, absent manifest error) that it is unable to
         ascertain the Federal Funds Rate for any reason, including but not
         limited to the inability of the Administrative Agent to obtain
         sufficient bids or publications in accordance with the terms hereof,
         the Base Rate shall be the Prime Rate until the circumstances giving
         rise to such inability no longer exist.

                 (b)      Eurodollar Loans.  Subject to Section 2.06(c), the
         Company agrees to pay interest in respect of the unpaid principal
         amount of each Eurodollar Loan from the date thereof until payment in
         full thereof at a rate per annum which shall be the sum of the
         Applicable Margin plus the relevant Eurodollar Rate, but in no event
         to exceed the Highest Lawful Rate.

                 (c)      Default Interest.  Overdue principal and, to the
         extent permitted by law, overdue interest in respect of each Loan and
         all other amounts owing hereunder shall bear interest for each day
         that such amounts are overdue at a rate per annum equal to two percent
         (2%) in excess of the Eurodollar Rate plus the Applicable Margin or
         the Base Rate, as applicable to such Loan, in effect for each such
         day, and all other amounts owing hereunder shall bear interest for
         each





                                     -23-
<PAGE>   29
         day that such amounts are overdue at a rate per annum equal to two
         percent (2%) in excess of the Base Rate, but in no event shall any
         such rate exceed the Highest Lawful Rate.

                 (d)      Interest Payment Dates.  Interest on each Loan shall
         accrue from and including the date of such Loan to but excluding the
         date of payment in full thereof.  Interest on each Eurodollar Loan
         shall be payable on the last day of each Interest Period applicable
         thereto and, in the case of an Interest Period in excess of three
         months, on each day which occurs every three months after the initial
         date of such Interest Period, and on any prepayment (on the amount
         prepaid), at maturity (whether by acceleration or otherwise) and,
         after maturity, on demand.  Interest on Base Rate Loans shall be
         payable on each Quarterly Date, commencing on the first of such days
         to occur after such Loan is made, at maturity (whether by acceleration
         or otherwise) and, after maturity, on demand.

                 (e)      Notice by the Administrative Agent.  The
         Administrative Agent, upon determining the Eurodollar Rate for any
         Interest Period, shall promptly notify by telephone (confirmed in
         writing) or in writing the Company and the Lenders thereof.

         Section 2.07     Interest Periods.  In connection with each Borrowing
of Eurodollar Loans, the Company shall elect an Interest Period to be
applicable to such Borrowing, which Interest Period shall begin on and include,
as the case may be, the date selected by the Company as of the date of the
Borrowing pursuant to Section 2.02(a), or at conversion from one Type of Loan
to another pursuant to Section 2.11(e), or the date of expiration of the then
current Interest Period applicable thereto, and end on but exclude the date
which is either one, two, three, six or 12 months thereafter, as selected by
the Company; provided that:

                 (a)      Business Days.  If any Interest Period would
         otherwise expire on a day which is not a Business Day, such Interest
         Period shall expire on the next succeeding Business Day, provided,
         further, that if any Interest Period (other than in respect of a
         Borrowing of Eurodollar Loans the Interest Period of which is expiring
         pursuant to Section 2.15(b) hereof) would otherwise expire on a day
         which is not a Business Day but is a day of the month after which no
         further Business Day occurs in such month, such Interest Period shall
         expire on the next preceding Business Day;

                 (b)      Month End.  Any Interest Period which begins on the
         last Business Day of a calendar month (or on a day for which there is
         no numerically corresponding day in the calendar month at the end of
         such Interest Period) shall, subject to Section 2.07(c) below, end on
         the last Business Day of a calendar month;

                 (c)      Payment Limitations.  No Interest Period shall extend
         beyond any date that any principal payment or prepayment is scheduled
         to be due unless the aggregate principal amount of Borrowings which
         are Borrowings of Base Rate Loans or which have Interest Periods which
         will expire on or before such date, less the aggregate amount of any
         other principal payments or prepayments due during such Interest
         Period, is equal to or in excess of the amount of such principal
         payment or prepayment; and

                 (d)      Maturity Dates.  No Interest Period with regard to
         Loans shall extend beyond the Maturity Date.





                                     -24-
<PAGE>   30
         Section 2.08     Repayment of Loans.  The Company will pay to the
Administrative Agent for account of each Lender the outstanding principal
amount of each Loan made by such Lender on or before the Maturity Date.

         Section 2.09     Termination or Reduction of Commitments.  The Company
may, upon at least 10 Business Days' notice to the Administrative Agent,
terminate entirely at any time the unused portions of the Commitments, or
proportionately reduce from time to time by an aggregate amount of $1,000,000
or any larger multiple thereof, the unused portions of the Commitments,
provided that any such reduction shall apply proportionately to the Commitment
of each Lender.  If the Commitments are terminated in their entirety, all
accrued commitment fees with respect thereto shall be payable on the effective
date of such termination.  The unused portions of the Commitments once
terminated or reduced may not be reinstated.

         Section 2.10     Prepayments.

                 (a)      Mandatory Borrowing Base Prepayments.  If, after
         giving effect to any reduction of the Maximum Loan Available Amount as
         a result of a redetermination or reduction of the Borrowing Base as
         provided in Section 2.20, the Aggregate Credit Exposure exceeds the
         amount of such redetermined Borrowing Base, the Company shall:

                          (A) within 90 days of the Company's receipt of
                 written notice from the Administrative Agent, either (i)
                 provide additional collateral pursuant to Section 2.24 as
                 security for the Lender Indebtedness, or (ii) pay or prepay
                 the Loans or provide Cover for LC Liabilities, or a
                 combination thereof, in an amount equal to at least 50% of
                 such excess; and

                          (B)     within 180 days of the Company's receipt of
                 the written notice referred to in Clause (A) of this Section
                 2.10(a), either (i) provide additional collateral pursuant to
                 Section 2.24 as security for the Lender Indebtedness, or (ii)
                 pay or prepay the Loans or provide cover for LC Liabilities,
                 or a combination thereof, in an amount equal to the remainder
                 of such excess.

         All prepayments pursuant to this Section 2.10(a) shall be applied
         first to Base Rate Loans and second to such Eurodollar Loans as the
         Company may designate.

                 (b)      Voluntary Prepayments.  The Company may, at its
         option, at any time and from time to time, prepay Loans, in whole or
         in part, without premium or penalty (other than funding losses, if
         any, resulting from such prepayment being made other than on the last
         day of an Interest Period with respect to any Eurodollar Loan as
         provided in Section 2.18), upon giving, in the case of a Eurodollar
         Loan, three Business Days' prior written notice to the Administrative
         Agent, and, in the case of a Base Rate Loan, one Business Day's prior
         written notice to the Administrative Agent.  Such notice shall be
         irrevocable and specify the date and amount of prepayment and the Loan
         or Loans (including the Type thereof) to which such prepayment is to
         be applicable.  The payment amount specified in such notice shall be
         due and payable on the date specified.  Each prepayment of Loans shall
         be in the minimum principal amount of $1,000,000 or any larger
         multiple thereof or the aggregate balance outstanding on the
         applicable Notes.  Each prepayment made pursuant to this Section shall
         be accompanied by any funding losses resulting





                                     -25-
<PAGE>   31
         from such prepayment being made other than on the last day of an
         Interest Period with respect to any Eurodollar Loan as provided in
         Section 2.18.  Each prepayment shall be applied ratably to prepay the
         Loans of the several Lenders.

                 (c)      Notice by Administrative Agent.  Upon receipt of a
         notice of prepayment pursuant to this Section, the Administrative
         Agent shall promptly notify each Lender of the contents thereof and of
         such Lender's ratable share of such prepayment.

         Section 2.11     Continuation and Conversion Options.

                 (a)      Continuation.  The Company may elect to continue all
         or any part of any Borrowing of Eurodollar Loans beyond the expiration
         of the then current Interest Period relating thereto by giving Advance
         Notice to the Administrative Agent of such election, specifying the
         Eurodollar Loan or portion thereof to be continued and the Interest
         Period therefor.  In the absence of such a timely and proper election
         with regard to Eurodollar Loans, the Company shall be deemed to have
         elected to convert such Eurodollar Loan to a Base Rate Loan pursuant
         to Section 2.11(d).

                 (b)      Amounts of Continuations.  All or part of any
         Eurodollar Loan may be continued as provided herein, provided that any
         continuation of such Loan shall not be (as to each Loan as continued
         for an applicable Interest Period) less than $3,000,000.

                 (c)      Continuation or Conversion Upon Default.  If no
         Default shall have occurred and be continuing, each Eurodollar Loan
         may be continued or converted as provided in this Section.  If a
         Default shall have occurred and be continuing, the Company shall not
         have the option to elect to continue any such Eurodollar Loan pursuant
         to Section 2.11(a) or to convert Base Rate Loans pursuant to Section
         2.11(e).

                 (d)      Conversion to Base Rate.  The Company may elect to
         convert any Eurodollar Loan on the last day of the then current
         Interest Period relating thereto to a Base Rate Loan by giving Advance
         Notice to the Administrative Agent of such election.

                 (e)      Conversion to Eurodollar Rate.  The Company may elect
         to convert any Base Rate Loan at any time or from time to time to a
         Eurodollar Loan by giving Advance Notice to the Administrative Agent
         of such election, specifying each Interest Period therefor.

                 (f)      Amounts of Conversions.  All or any part of the
         outstanding Loans may be converted as provided herein, provided that
         any conversion of such Loans shall not result in a Borrowing of
         Eurodollar Loans in an amount less than $3,000,000 and in integral
         multiples of $1,000,000.

         Section 2.12     Fees.

                 (a)      Commitments.  The Company shall pay Administrative
         Agent for the account of and distribution to each Lender in accordance
         with its Percentage Share the following commitment fees:





                                     -26-
<PAGE>   32
                          (i)     A commitment fee, which commitment fee shall
                 accrue for the period commencing on the Closing Date to and
                 including the Maturity Date (or such earlier date as the
                 Commitments shall have been terminated entirely).  The
                 commitment fee payable pursuant to this Section 2.12(a) shall
                 be the product of the applicable Commitment Fee Rate from the
                 table below and the average daily excess amount of the
                 Designated Borrowing Base over the Aggregate Credit Exposure.
                 Such commitment fees shall be payable in arrears on the
                 Quarterly Dates, commencing on the first Quarterly Date to
                 occur after the Closing Date.  The rates set forth in the
                 table below are based upon the Company's Maximum Available
                 Amount Utilization Percentage as of any day, where the term
                 "Maximum Available Amount Utilization Percentage" means as of
                 any day, the fraction, expressed as a percentage, the
                 numerator of which is the Aggregate Credit Exposure on such
                 day, and the denominator of which is the Borrowing Base in
                 effect on such day:

</TABLE>

                          (ii)    An unavailable commitment fee on the daily
                 average difference between the Designated Borrowing Base and
                 the lesser of (A) the Commitments or (B) the Borrowing Base
                 for the period from and including the last Borrowing Base
                 determination date to the earlier of the date the Commitments
                 are terminated or the date of the next Borrowing Base
                 determination at a rate per annum equal to 50% of the
                 applicable rate per annum outlined in clause (i) above.

                          (iii)   If the Designated Borrowing Base is increased
                 pursuant to the proviso of Section 2.20(e), an additional
                 commitment fee for the period beginning on the most recent
                 regularly scheduled Borrowing Base determination date
                 (pursuant to Section 2.20) to the date on which the Designated
                 Borrowing Base is so increased at the applicable rate per
                 annum set forth in clause (i) above; provided, however, in
                 cases under this clause (iii), the Company shall receive
                 credit for applicable amounts already paid pursuant to clause
                 (ii) above.

                 (b)      Letters of Credit.  As consideration for the issuance
         of any Letter of Credit, the Company will pay to the Issuing Bank a
         fee on the daily average amount available for drawings under each
         Letter of Credit, in each case for the period from and including the
         date of issuance of such Letter of Credit to and excluding the date of
         expiration or termination thereof.  The letter of credit fee payable
         pursuant to this Section 2.12(b) shall be the product of the
         applicable Letter of Credit Fee Rate from the table below and the
         average daily amount available for drawings under each Letter of
         Credit, provided that each Letter of Credit shall bear a minimum fee
         of





                                     -27-
<PAGE>   33
         $400.  Such letter of credit fees shall be payable in arrears on each
         Quarterly Date.  The rates set forth in the table below are based upon
         the Company's Maximum Available Amount Utilization Percentage as of
         any day, where the term "Maximum Available Amount Utilization
         Percentage" means as of any day, the fraction, expressed as a
         percentage, the numerator of which is the Aggregate Credit Exposure on
         such day, and the denominator of which is the Borrowing Base in effect
         on such day:

</TABLE>

         In addition to the fees set forth above for the benefit of the
         Lenders, the Company shall pay to the Issuing Bank for its own account
         (i) a fronting fee in an amount equal to 1/8 of 1% per annum of the
         face amount of the Letters of Credit outstanding as consideration for
         capital costs incurred for retaining the full amount of each Letter of
         Credit issued hereunder on its books, and (ii) with respect to any
         amendment or transfer of any Letter of Credit and for each drawing
         made thereunder, documentary and processing charges in accordance with
         the Issuing Bank's standard schedule for such charges as disclosed to
         the Company in a letter of even date herewith, as the case may be.
         Such fees shall be due and payable in arrears on each Quarterly Date.

                 (c)      Incremental Borrowing Base Increase.  The Company
         shall pay Administrative Agent for the account of and distribution to
         each Lender in accordance with its Percentage Share a redetermination
         fee in an amount equal to 0.100% of each incremental increase in the
         Borrowing Base (resulting from a redetermination of the Borrowing Base
         pursuant to Section 2.20); provided, however, such redetermination fee
         shall be payable only on that portion of such redetermined Borrowing
         Base which exceeds the highest previous Borrowing Base of $165,000,000
         or more.

         Section 2.13     Payments, etc.

                 (a)      Without Setoff, etc.  Except as otherwise
         specifically provided herein, all payments under this Agreement shall
         be made to the Administrative Agent on behalf of the Lenders without
         defense, set-off or counterclaim to the Administrative Agent not later
         than 12:00 noon (New York time) on the date when due and shall be made
         in Dollars in immediately available funds at the Payment Office.  The
         Administrative Agent will promptly thereafter distribute funds in the
         form received relating to the payment of principal or interest or
         commitment fees ratably to the Lenders for the account of their
         respective Lending Offices, and funds in the form received relating to
         the payment of any other amount payable to any Lender to such Lender
         for the account of its Lending Office.

                 (b)      Non-Business Days.  Whenever any payment to be made
         hereunder or under any Note shall be stated to be due on a day which
         is not a Business Day, the due date thereof shall be extended to the
         next succeeding Business Day (except as otherwise provided in Section
         2.07) and, with respect to payments of principal, interest thereon
         shall be payable at the applicable rate during such extension.

                 (c)      Computations.  All computations of interest shall be
         made on the basis of a year of 360 days (unless such calculation would
         result in a usurious rate, in which case interest shall be calculated
         on the basis of a year of 365 or 366 days, as the case may be) in the
         case of Base Rate Loans when determined by Section 2.06(a)(ii) and in
         the case of Eurodollar Loans, and 365 or 366 days (as the case may be)
         in the case of Base Rate Loans when determined by Section 2.06(a)(i),
         and all computations of fees shall be made on the basis of a year of
         360 days (unless such calculation would result in a usurious rate, in
         which case interest shall be calculated on the basis of a year of 365
         or 366 days, as the case may be), in each case for the actual number
         of days (including the first day but excluding the last day) occurring
         in the period for which such interest or fees are payable.  Each
         determination by the Administrative Agent of an interest rate or fee
         hereunder shall, except for manifest error, be final, conclusive and
         binding for all purposes, provided that such determination shall be
         made in good faith in a manner generally consistent with the
         Administrative Agent's standard practice.  If the Administrative Agent
         and the Company determine that manifest error exists, such parties
         shall correct such error by way of an adjustment to the payment due on
         the next Quarterly Date.

         Section 2.14     Interest Rate Not Ascertainable, etc.  In the event
that the Administrative Agent shall have determined (which determination shall
be reasonably exercised and shall, absent manifest error, be final, conclusive
and binding upon all parties) that on any date for determining the Eurodollar
Rate for any Interest Period, by reason of any changes arising after the date
of this Agreement affecting the interbank Eurodollar market, or any Lender's
position in such market, adequate and fair means do not exist for ascertaining
the applicable interest rate on the basis provided for in the definition of
Eurodollar Rate, then, and in any such event, the Administrative Agent shall
forthwith give notice (by telephone confirmed in writing) to the Company and to
the Lenders of such determination.  Until the Administrative Agent notifies the
Company that the circumstances giving rise to the suspension described herein
no longer exist, the obligations of the Lenders to make Eurodollar Loans shall
be immediately suspended; any Eurodollar Loan that is requested (by
continuation, conversion or otherwise) shall instead be made as a Base Rate
Loan, and any outstanding Eurodollar Loan shall be converted, on the last day
of the then current Interest Period applicable thereto, to a Base Rate Loan.

         Section 2.15     Illegality.

                 (a)      Determinations of Illegality.  In the event that any
         Lender shall have determined (which determination shall be reasonably
         exercised and shall, absent manifest error, be final, conclusive and
         binding upon all parties) at any time that the making or continuance
         of any Eurodollar Loan has become unlawful by compliance by such
         Lender in good faith with any applicable law, governmental rule,
         regulation, guideline or order (whether or not having the force of law
         and whether or not failure to comply therewith would be unlawful),
         then, in any such event, the Lender shall give prompt notice (by
         telephone confirmed in writing) to the Administrative Agent of such
         determination (which notice the Administrative Agent shall promptly
         transmit to the Company and the other Lenders).

                 (b)      Eurodollar Loans Suspended.  Upon the giving of the
         notice to the Company referred to in Section (a) above, (i) the
         Company's right to request (by continuation, conversion or otherwise)
         and such Lender's obligation to make Eurodollar Loans shall be
         immediately suspended, and any such requested Eurodollar Loan shall
         instead be made as a Base Rate Loan, and (ii) if the affected
         Eurodollar Loan or Loans are then outstanding, the Company shall
         immediately, or if permitted by applicable law, no later than the date
         permitted thereby, upon at least one Business Day's written notice to
         the Administrative Agent and the affected Lender, convert each such
         Eurodollar Loan into a Base Rate Loan, provided that if more than one
         Lender is affected at any time, then all affected Lenders must be
         treated the same pursuant to this Section.

         Section 2.16     Increased Costs.

                 (a)      Eurodollar Regulations, etc.  If, by reason of (x)
         after the date hereof, the introduction of or any change (including,
         but not limited to, any change by way of imposition or increase of
         reserve requirements) in or in the interpretation of any law or
         regulation, or (y) the compliance with any guideline or request made
         after the date hereof by any central bank or other governmental
         authority or quasi-governmental authority exercising control over
         banks or financial institutions generally (whether or not having the
         force of law):

                          (i)     any Lender (or its applicable Lending Office)
                 shall be subject to any tax, duty or other charge with respect
                 to its Eurodollar Loans or its obligation to make Eurodollar
                 Loans, or shall change the basis of taxation of payments to
                 any Lender of the principal of or interest on its Eurodollar
                 Loans or its obligation to make Eurodollar Loans (except for
                 changes in the rate of tax on the overall net income or gross
                 receipts of such Lender or its applicable Lending Office
                 imposed by the jurisdiction in which such Lender's principal
                 executive office or applicable Lending Office is located); or

                          (ii)    any reserve (including, but not limited to,
                 any imposed by the Board of Governors of the Federal Reserve
                 System), special deposit or similar requirement against assets
                 of, deposits with or for the account of, or credit extended
                 by, any Lender's applicable Lending Office shall be imposed or
                 deemed applicable or any other condition affecting its
                 Eurodollar Loans or its obligations to make Eurodollar Loans
                 shall be imposed on any Lender or its applicable Lending
                 Office or the interbank Eurodollar market or the secondary
                 certificate of deposit market;

         and as a result thereof there shall be any increase in the cost to
         such Lender of agreeing to make or making, funding or maintaining
         Eurodollar Loans (except to the extent already included in the
         determination of the applicable Eurodollar Rate) or there shall be a
         reduction in the amount received or receivable by such Lender or its
         applicable Lending Office, then the Company shall from time to time,
         upon written notice from and demand by such Lender (with a copy of
         such notice and demand to the Administrative Agent), pay to such
         Lender, within 30 days after the date specified in such notice and
         demand, additional amounts determined by such Lender in a reasonable
         manner to be sufficient to indemnify such Lender against such
         increased cost.  A certificate as to the amount of such increased cost
         and the calculation thereof, submitted to the Company and the
         Administrative Agent by such Lender, shall, except for manifest error,
         be final,





                                     -30-
<PAGE>   36
         conclusive and binding for all purposes, provided that the
         determination of such amount shall be made in good faith in a manner
         generally consistent with such Lender's standard practice.

                 (b)      Costs.  If any Lender shall advise the Administrative
         Agent that at any time, because of the circumstances described in
         clauses (x) or (y) in Section 2.16(a) or any other circumstances
         arising after the Effective Date affecting such Lender or the
         interbank Eurodollar market or such Lender's position in such market,
         the Eurodollar Rate, as determined in good faith by the Administrative
         Agent, will not adequately and fairly reflect the cost to such Lender
         of funding its Eurodollar Loans, then, and in any such event:

                          (i)     the Administrative Agent shall forthwith give
                 notice (by telephone confirmed in writing) to the Company and
                 to the Lenders of such advice; and

                          (ii)    the Company's right to request and such
                 Lender's obligation to make Eurodollar Loans shall be
                 immediately suspended, any such Eurodollar Loan that is
                 requested (by continuation, conversion or otherwise) shall
                 instead be made as a Base Rate Loan, and any such outstanding
                 Eurodollar Loan shall be converted, on the last day of the
                 then current Interest Period applicable thereto, to a Base
                 Rate Loan.

                 (c)      Capital Adequacy.  If, by reason of (i) after the
         date hereof, the introduction of or any change (including, but not
         limited to, any change by way of imposition or increase of reserve
         requirements) in or in the interpretation of any law or regulation, or
         (ii) the compliance with any guideline or request made after the date
         hereof by any central bank or other governmental authority or
         quasi-governmental authority exercising control over banks or
         financial institutions generally (whether or not having the force of
         law) affects or would affect the amount of capital required to be
         maintained by any Lender or any corporation controlling such Lender,
         and the amount of such capital is increased by or based upon the
         existence of such Lender's Commitment to lend hereunder and other
         commitments of this type or of the Letters of Credit (or similar
         contingent obligations), then, within 30 days after written request
         therefor by such Lender (with a copy of such request to the
         Administrative Agent), the Company shall pay to such Lender, from time
         to time as specified by such Lender, additional amounts sufficient to
         compensate such Lender for the increased cost of such additional
         capital in light of such circumstances, to the extent that such Lender
         reasonably determines such increase in capital to be allocable to the
         existence of such Lender's Commitment to lend hereunder or to the
         issuance or maintenance of the Letters of Credit.  A certificate as to
         such amounts and the calculation thereof, submitted to the Company and
         the Administrative Agent by such Lender, shall be conclusive and
         binding for all purposes, absent manifest error, provided that the
         determination of such amount shall be made in good faith in a manner
         generally consistent with such Lender's standard practice.

                 (d)      Issuing Bank.  The rights and benefits of the Lenders
         under this Section 2.16 shall also apply to the Issuing Bank in its
         capacity as such.

                 (e)      Notice.  The Company shall not be obligated to
         compensate any Lender pursuant to this Section 2.16 for any amounts
         attributable to a period more than 90 days prior to the giving of
         notice by such Lender to the Company of its intention to seek
         compensation under this Section 2.16.





                                     -31-
<PAGE>   37
         Section 2.17     Change of Lending Office.  Each Lender agrees that it
will use reasonable efforts to designate an alternate Lending Office with
respect to any of its Eurodollar Loans affected by the matters or circumstances
described in Sections 2.14, 2.15 or 2.16 to reduce the liability of the Company
or avoid the results provided thereunder, so long as such designation is not
disadvantageous to such Lender as determined by such Lender in its sole
discretion.

         Section 2.18     Funding Losses.  The Company shall compensate each
Lender, upon its written request (which request shall set forth the basis for
requesting such amounts and which request shall be reasonably exercised and
shall, absent manifest error, be final, conclusive and binding upon all of the
parties hereto), for all losses, expenses and liabilities (including, but not
limited to, any interest paid by such Lender to lenders of funds borrowed by it
to make or carry its Eurodollar Loans to the extent not recovered by the Lender
in connection with the re-employment of such funds and including loss of
anticipated profits), which the Lender may sustain (i) if for any reason (other
than a default by such Lender) a Borrowing of Eurodollar Loans does not occur
on the date specified therefor in a Borrowing Request (whether or not
withdrawn), (ii) if any repayment (or conversion pursuant to Section 2.15 or
otherwise) of any of its Eurodollar Loans occurs on a date which is not the
last day of an Interest Period applicable thereto, or (iii) if, for any reason,
the Company defaults in its obligation to repay its Eurodollar Loans when
required by the terms of this Agreement.

         Section 2.19     Sharing of Payments, etc.  If any Lender shall obtain
any payment or reduction (including, but not limited to, any amounts received
as adequate protection of a deposit treated as cash collateral under the
Bankruptcy Code) of any obligation of the Company hereunder (whether voluntary,
involuntary, through the exercise of any right of set-off, or otherwise) in
excess of its ratable share of payments or reductions on account of such
obligations obtained by all the Lenders, such Lender shall forthwith (i) notify
each of the other Lenders and the Administrative Agent of such receipt, and
(ii) purchase from the other Lenders such participations in the affected
obligations as shall be necessary to cause such purchasing Lender to share the
excess payment or reduction, net of costs incurred in connection therewith,
ratably with each of them, provided that if all or any portion of such excess
payment or reduction is thereafter recovered from such purchasing Lender or
additional costs are incurred, the purchase shall be rescinded and the purchase
price restored to the extent of such recovery or such additional costs, but
without interest.  The Company agrees that any Lender so purchasing a
participation from another Lender pursuant to this Section may, to the fullest
extent permitted by law, exercise all its rights of payment (including the
right of set-off) with respect to such participation as fully as if such Lender
were the direct creditor of the Company in the amount of such participation.

         Section 2.20     Borrowing Base.

                 (a)      Redetermination Date; Initial Borrowing Base.  The
         Borrowing Base shall be determined in accordance with Section 2.20(b)
         by the Determining Lenders and is subject to redetermination in
         accordance with Section 2.20(d).  Upon any redetermination of the
         Borrowing Base, such redetermination shall remain in effect until the
         next successive Redetermination Date.  "Redetermination Date" means
         the date that the redetermined Borrowing Base becomes effective
         subject to the notice requirements specified in Section 2.20(f) both
         for scheduled redeterminations and unscheduled redeterminations.  The
         amount of the initial Borrowing Base during the period from and after
         the Closing Date until the first scheduled redetermination of the
         Borrowing Base, shall be $165,000,000.





                                     -32-
<PAGE>   38
                 (b)      Redetermination.  Upon receipt of the Reserve Report
         by the Determining Lenders, the Determining Lenders will redetermine
         the Borrowing Base.  Such redetermination by the Determining Lenders
         will be in accordance with its normal and customary procedures for
         evaluating oil and gas reserves and other related assets as such exist
         at that particular time and will otherwise be in their sole
         discretion.  The Determining Lenders shall propose such redetermined
         Borrowing Base to the Lenders within 30 days following receipt by the
         Determining Lenders and the Lenders of the complete Reserve Report.
         After having received notice of such proposal by the Determining
         Lenders, the Required Lenders shall have 15 days to agree or disagree
         with such proposal.  If at the end of the 15 days, the Required
         Lenders have not communicated their approval or disapproval, such
         silence shall be deemed to be an approval and the Determining Lenders'
         proposal shall be the new Borrowing Base.  If however, the Required
         Lenders notify Determining Lenders within 15 days of their
         disapproval, the Required Lenders shall, within a reasonable period of
         time, agree on a new Borrowing Base.  In taking the above actions,
         each Determining Lender shall act in accordance with its normal and
         customary procedures for evaluating oil and gas reserves and other
         related assets as such exist at that particular time and will
         otherwise act in their sole discretion.

                 (c)      Exclusion of Certain Property.  Without limiting the
         provisions of this Section 2.20 with respect to scheduled and
         unscheduled Borrowing Base redeterminations, if at any time, any
         Determining Lender receives information not previously available to
         any of the Determining Lenders which could reasonably cause a
         deterioration in the PV10 value (as stated in the most recent Reserve
         Report furnished to the Lenders pursuant to Section 5.02(e)) of the BB
         Properties (or any part thereof) in an amount equal to or greater than
         $10,000,000, or such Property is not assignable, then the Determining
         Lenders may exclude any such Property or portion of production
         therefrom or any income from such Property from the Borrowing Base
         (thereby reducing the Borrowing Base).

                 (d)      Time of Redetermination, etc.  So long as any of the
         Commitments are in effect and so long as there remains any Credit
         Exposure as to any Lender, on or around the first Business Day of each
         April, commencing April 1, 1997 (each being a "Scheduled
         Redetermination Date"), the Determining Lenders shall redetermine the
         amount of the Borrowing Base in accordance with Section 2.20(b).  The
         Company may from time to time request additional redeterminations of
         the Borrowing Base from the Determining Lenders, whereupon the
         Determining Lenders shall redetermine the Borrowing Base in accordance
         with Section 2.20(b); provided, however, in no event shall the
         Determining Lenders be obligated to grant more than two (2) such
         requests in any fiscal year of the Company.  In the event of any such
         unscheduled redetermination, the Determining Lenders shall redetermine
         the amount of the Borrowing Base in accordance with Section 2.20(b).
         At the reasonable request of the Required Lenders, the Determining
         Lenders shall redetermine the Borrowing Base; provided, however, only
         one (1) such request may be made in any fiscal year of the Company
         (exclusive of any reduction in the Borrowing Base pursuant to Section
         2.20(c)).  In the event of any such unscheduled redetermination, the
         Determining Lenders shall redetermine the amount of the Borrowing Base
         in accordance with Section 2.20.

                 (e)      Designated Borrowing Base.  Upon the Company's
         receipt of written notice (each a "Borrowing Base Notice") from the
         Administrative Agent of the amount of the Borrowing Base then in
         effect, the Company may accept all or a lesser amount of such
         Borrowing Base (the





                                     -33-
<PAGE>   39
         "Designated Borrowing Base") by providing written notice to the
         Administrative Agent (which notice the Administrative Agent shall
         promptly transmit to the Determining Lenders) of the amount of the
         Designated Borrowing Base within 5 Business Days following receipt of
         a Borrowing Base Notice from the Administrative Agent; provided,
         however, the Designated Borrowing Base shall not be less than the
         lower of (i) the amount of the Borrowing Base then in effect, or (ii)
         $75,000,000, and shall not be greater than the lower of (i) the
         Borrowing Base then in effect, or (ii) the aggregate amount of the
         Commitments.  If the Company does not provide written notice to the
         Administrative Agent within 5 Business Days following receipt of a
         Borrowing Base Notice, the Designated Borrowing Base shall be equal to
         the Borrowing Base as set forth in such Borrowing Base Notice;
         provided, however, that during each Borrowing Base period and after
         the expiration of such 5 Business Day period, the Company may adjust
         the Designated Borrowing Base (subject to the limitations set forth in
         the first sentence of this Section 2.20(e)) by providing the
         Administrative Agent with written notice (which notice the
         Administrative Agent shall promptly transmit to the Determining
         Lenders) at least 5 Business Days in advance of the effective date of
         a different Designated Borrowing Base.  During the period from and
         after the Closing Date to and including the effective date of the next
         designation of the Designated Borrowing Base in accordance with this
         Section 2.20, the amount of the Designated Borrowing Base shall be
         $165,000,000.

                 (f)      Notice by Administrative Agent.  The Administrative
         Agent shall promptly notify in writing the Company of the new
         Borrowing Base.  Any redetermination of the Borrowing Base shall not
         be in effect until written notice is received by the Company.

         Section 2.21     Taxes.

                 (a)      Payments Free and Clear.  Any and all payments by the
         Company under this Agreement or any other Financing Document shall be
         made, in accordance with Section 2.13, free and clear of and without
         deduction for any and all present or future taxes, levies, imposts,
         deductions, charges or withholdings, and all liabilities with respect
         thereto, excluding, in the case of each Lender, the Administrative
         Agent and the Issuing Bank, taxes imposed on or measured by its income
         or receipts, and franchise or similar taxes imposed on it, by (i) any
         jurisdiction (or political subdivision thereof) of which the
         Administrative Agent, the Issuing Bank or such Lender, as the case may
         be, is a citizen or resident or in which such Lender has a permanent
         establishment (or is otherwise engaged in the active conduct of its
         banking business through an office or a branch) which is such Lender's
         applicable Lending Office, (ii) the jurisdiction (or any political
         subdivision thereof) in which the Administrative Agent, the Issuing
         Bank or such Lender is organized, or (iii) any jurisdiction (or
         political subdivision thereof) in which such Lender, the Issuing Bank
         or the Administrative Agent is presently doing business which taxes
         are imposed solely as a result of doing business in such jurisdiction
         (all such non- excluded taxes, levies, imposts, deductions, charges,
         withholdings and liabilities so arising out of payments by the Company
         being hereinafter referred to as "Taxes").  If the Company shall be
         required by law to deduct any Taxes from or in respect of any sum
         payable hereunder to the Lenders, the Issuing Bank or the
         Administrative Agent (i) the sum payable shall be increased by the
         amount necessary so that after making all required deductions
         (including deductions applicable to additional sums payable under this
         Section 2.21) such Lender, the Issuing Bank or the Administrative
         Agent (as the case may be) shall receive an amount equal to the sum it
         would have received had no such deductions been made, (ii) the Company
         shall make such deductions, and (iii) the Company shall





                                     -34-
<PAGE>   40
         pay the full amount deducted to the relevant taxing authority or other
         Governmental Authority in accordance with applicable law.

                 (b)      Other Taxes.  In addition, the Company agrees to pay
         any present or future stamp or documentary taxes or any other excise
         or property taxes, charges or similar levies that arise from any
         payment made hereunder or from the execution, delivery or registration
         of, or otherwise with respect to, this Agreement, any Assignment and
         Acceptance or any other Financing Document (hereinafter referred to as
         "Other Taxes").

                 (C)      INDEMNIFICATION.  THE COMPANY WILL INDEMNIFY EACH
         LENDER, THE ISSUING BANK AND THE ADMINISTRATIVE AGENT FOR THE FULL
         AMOUNT OF TAXES AND OTHER TAXES (INCLUDING, BUT NOT LIMITED TO, ANY
         TAXES OR OTHER TAXES IMPOSED BY ANY JURISDICTION ON AMOUNTS PAYABLE
         UNDER THIS SECTION 2.21) PAID BY SUCH LENDER OR THE ISSUING BANK OR
         THE ADMINISTRATIVE AGENT (ON THEIR BEHALF OR ON BEHALF OF ANY LENDER),
         AS THE CASE MAY BE, AND ANY LIABILITY (INCLUDING PENALTIES, INTEREST
         AND EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR
         NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY ASSERTED.  ANY
         PAYMENT PURSUANT TO SUCH INDEMNIFICATION SHALL BE MADE WITHIN 30 DAYS
         AFTER THE DATE ANY LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE
         AGENT, AS THE CASE MAY BE, MAKES WRITTEN DEMAND THEREFOR.  IF ANY
         LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE AGENT RECEIVES A REFUND
         OR CREDIT IN RESPECT OF ANY TAXES OR OTHER TAXES FOR WHICH SUCH
         LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE AGENT HAS RECEIVED
         PAYMENT FROM THE COMPANY HEREUNDER IT SHALL PROMPTLY NOTIFY THE
         COMPANY OF SUCH REFUND OR CREDIT AND SHALL, WITHIN 30 DAYS AFTER
         RECEIPT OF A REQUEST BY THE COMPANY (OR PROMPTLY UPON RECEIPT, IF THE
         COMPANY HAS REQUESTED APPLICATION FOR SUCH REFUND OR CREDIT PURSUANT
         HERETO), PAY AN AMOUNT EQUAL TO SUCH REFUND OR CREDIT TO THE COMPANY
         WITHOUT INTEREST (BUT WITH ANY INTEREST SO REFUNDED OR CREDITED),
         PROVIDED THAT THE COMPANY, UPON THE REQUEST OF SUCH LENDER, THE
         ISSUING BANK OR THE ADMINISTRATIVE AGENT, AGREES TO RETURN SUCH REFUND
         OR CREDIT (PLUS PENALTIES, INTEREST OR OTHER CHARGES) TO SUCH LENDER,
         THE ISSUING BANK OR THE ADMINISTRATIVE AGENT IN THE EVENT SUCH LENDER,
         THE ISSUING BANK OR THE ADMINISTRATIVE AGENT IS REQUIRED TO REPAY SUCH
         REFUND OR CREDIT.

                 (d)      Receipts.  Within 30 days after the date of any
         payment of Taxes or Other Taxes withheld by the Company in respect of
         any payment to any Lender, the Issuing Bank or the Administrative
         Agent, the Company will furnish to the Administrative Agent the
         original or a certified copy of a receipt evidencing payment thereof.

                 (e)      Survival.  Without prejudice to the survival of any
         other agreement contained herein, the agreements and obligations
         contained in this Section 2.21 shall survive the payment in full of
         principal and interest hereunder.

                 (f)      Lender Representations.  Each Lender represents that
         it is either (i) a corporation organized under the laws of the United
         States of America or any state thereof or (ii) entitled to complete
         exemption from United States withholding tax imposed on or with
         respect to any payments, including fees, to be made to it pursuant to
         this Agreement (A) under an applicable





                                     -35-
<PAGE>   41
         provision of a tax convention to which the United States of America is
         a party or (B) because it is acting through a branch, agency or office
         in the United States of America and any payment to be received by it
         hereunder is effectively connected with a trade or business in the
         United States of America.  Each Lender that is not a corporation
         organized under the laws of the United States of America or any state
         thereof agrees to provide to the Company and the Administrative Agent
         on the Effective Date, or on the date of its delivery of the
         Assignment and Acceptance pursuant to which it becomes a Lender, and
         at such other times as required by United States law or as the Company
         or the Administrative Agent shall reasonably request, two accurate and
         complete original signed copies of either (A) Internal Revenue Service
         Form 4224 (or successor form) certifying that all payments to be made
         to it hereunder will be effectively connected to a United States trade
         or business (the "Form 4224 Certification") or (B) Internal Revenue
         Service Form 1001 (or successor form) certifying that it is entitled
         to the benefit of a provision of a tax convention to which the United
         States of America is a party which completely exempts from United
         States withholding tax all payments to be made to it hereunder (the
         "Form 1001 Certification").  In addition, each Lender agrees that if
         it previously filed a Form 4224 Certification it will deliver to the
         Company and the Administrative Agent a new Form 4224 Certification
         prior to the first payment date occurring in each of its subsequent
         taxable years; and if it previously filed a Form 1001 Certification,
         it will deliver to the Company and the Administrative Agent a new
         certification prior to the first payment date falling in the third
         year following the previous filing of such certification.  Each Lender
         also agrees to deliver to the Company and the Administrative Agent
         such other or supplemental forms as may at any time be required as a
         result of changes in applicable law or regulation in order to confirm
         or maintain in effect its entitlement to exemption from United States
         withholding tax on any payments hereunder, provided that the
         circumstances of the Lender at the relevant time and applicable laws
         permit it to do so.  If a Lender determines, as a result of any change
         in either (i) applicable law, regulation or treaty, or in any official
         application thereof or (ii) its circumstances, that it is unable to
         submit any form or certificate that it is obligated to submit pursuant
         to this Section, or that it is required to withdraw or cancel any such
         form or certificate previously submitted, it shall promptly notify the
         Company and the Administrative Agent of such fact.  If a Lender is
         organized under the laws of a jurisdiction outside the United States
         of America, unless the Company and the Administrative Agent have
         received a Form 1001 Certification or Form 4224 Certification
         satisfactory to them indicating that all payments to be made to such
         Lender hereunder are not subject to United States withholding tax, the
         Company shall withhold taxes from such payments at the applicable
         statutory rate, provided that such withholding shall not increase the
         amount of payments for the account of such Lender to be made by the
         Company pursuant to Section 2.21(a).  Each Lender agrees to indemnify
         and hold harmless from any United States taxes, penalties, interest
         and other expenses, costs and losses incurred or payable by (i) the
         Administrative Agent as a result of such Lender's failure to submit
         any form or certificate that it is required to provide pursuant to
         this Section or (ii) the Company or the Administrative Agent as a
         result of their reliance on any such form or certificate which it has
         provided to them pursuant to this Section.

                 (g)      Efforts to Avoid or Reduce.  Any Lender claiming any
         additional amounts payable pursuant to this Section 2.21 shall use
         reasonable efforts (consistent with legal and regulatory restrictions)
         to file any certificate or document requested by the Company or the
         Administrative Agent or to change the jurisdiction of its applicable
         Lending Office or to contest any tax imposed if the making of such a
         filing or change or contesting such tax would avoid the





                                     -36-
<PAGE>   42
         need for or reduce the amount of any such additional amounts that may
         thereafter accrue and would not, in the sole determination of such
         Lender, be otherwise disadvantageous to such Lender.

         Section 2.22     Pro Rata Treatment.  Except as required under Section
2.15, 2.16 or 2.18, each Borrowing, each payment or prepayment of principal of
any Borrowing, each payment of interest on the Loans, each payment of the fees,
each reduction of the Commitments, and each refinancing of any Borrowing with,
conversion of any Borrowing to or continuation of any Borrowing as a Borrowing
of any Type shall be allocated ratably and pro rata among the Lenders in
accordance with their respective Percentage Shares.  Each Lender agrees that in
computing such Lender's portion of any Borrowing to be made hereunder, the
Administrative Agent may, in its discretion, round each Lender's portion of
such Borrowing to the next higher or lower whole dollar amount.

         Section 2.23     Disposition of Proceeds.  The Mortgage contains (and
other Security Instruments may contain) an assignment by the Company to the
Administrative Agent of all production and all proceeds attributable thereto
which may be produced from or allocated to the Oil and Gas Properties described
therein and further provides in general for the application of such proceeds to
the satisfaction of the indebtedness, liabilities and obligations described
therein and secured thereby.  Notwithstanding such assignments, the
Administrative Agent, the Issuing Bank and the Lenders hereby grant to the
Company a license to receive, collect and use the proceeds attributable to such
production and agree not to notify the purchaser or purchasers of such
production and not to take any other action to cause such proceeds to be
remitted to the Administrative Agent, the Issuing Bank or the Lenders, in each
case unless and until an Event of Default has occurred and is continuing;
provided that so long as no Event of Default has occurred and is continuing,
the Administrative Agent shall execute and deliver a letter in the form of
Exhibit F to such Persons as the Company may direct; provided, further, if the
Administrative Agent, the Issuing Bank or any Lender shall receive any such
proceeds directly from any such purchaser prior to the occurrence and
continuation of an Event of Default, then such Person so receiving such
proceeds shall notify the Company thereof and upon request of the Company and
pursuant to its written instructions shall promptly remit such proceeds to the
Company.

         Section 2.24     Additional Collateral.  If at any time the Aggregate
Credit Exposure exceeds the Borrowing Base then in effect, and the Company does
not make the mandatory principal prepayment pursuant to Section 2.10(a), the
Company shall, as provided in Section 2.10(a), grant to the Administrative
Agent, as security for the Lender Indebtedness, a first-priority Lien on such
additional Properties of the Company or its Subsidiaries as is acceptable to
the Administrative Agent and the Lenders and having a fair market value equal
to or greater than the amount of such excess. Such Liens will be created and
perfected by and in accordance with the provisions of security agreements,
deeds of trust, mortgages, financing statements or other Security Instruments,
all in form and substance satisfactory to the Administrative Agent and in
sufficient executed (and acknowledged where necessary or appropriate)
counterparts for recording purposes.

full, and the Administrative Agent shall have received the following, each

         title to Oil and Gas Properties with a value (as determined by the
         Administrative Agent) at least equal to 80% of the total value of the
         Oil and Gas Properties that will constitute BB Properties.

                 (g)      Environmental Report.  The environmental site
         assessment report prepared by Highlander Environmental Corporation for
         the Company and such other reviews or further assessments that may be
         determined to be required by the Administrative Agent, in its sole
         discretion, to assess existence of any environmental items which could
         reasonably be expected to have a Material Adverse Affect.

                 (h)      Mobil Transaction.

                          (i)     A fully executed copy of the Mobil Purchase
                 and Sale Agreement; and

                          (ii)    Evidence reasonably satisfactory to the
                 Administrative Agent that the Company will purchase from Mobil
                 the assets referred to in the Mobil Purchase and Sale
                 Agreement concurrently with the funding of the Loan requested
                 by the Company for that purpose.

                 (i)      Miscellaneous.  Such other documents or conditions
         precedent which the Administrative Agent may reasonably have requested
         or require in its sole discretion.

         Section 3.03     Conditions Precedent to Each Loan.  At the time of
the making by such Lender of each Loan, including the initial Loan but not
including continuations or conversions pursuant to





                                     -39-
<PAGE>   45
Section 2.11 (before as well as after giving effect to such Loan and to the
proposed use of the proceeds thereof):

                 (a)      Notes.  The Company shall have issued, executed and
         delivered the Notes;

                 (b)      No Default.  There shall exist no Default or Event of
         Default;

                 (c)      Representations and Warranties.  Except for facts
         timely disclosed to the Administrative Agent from time to time in
         writing, not materially more adverse to the Company and its
         Subsidiaries than those existing on the Effective Date, all
         representations and warranties contained herein and in the other
         Financing Documents executed and delivered on or after the date hereof
         shall be true and correct in all material respects with the same
         effect as though such representations and warranties had been made on
         and as of the date of such Loan; and

                 (d)      Documentation.  The Administrative Agent shall have
         received such other documents as the Administrative Agent or any
         Lender or special counsel to the Administrative Agent may reasonably
         request, all in form and substance satisfactory to the Administrative
         Agent.

         Each Borrowing Request submitted by the Company, and the acceptance by
the Company of the proceeds of such Borrowing (but not including continuations
or conversions pursuant to Section 2.11), shall constitute a representation and
warranty by the Company, as of the date of the Loans comprising such Borrowing,
that the conditions specified in Sections 3.03(b) and (c) have been satisfied.

         Section 3.04     Recordings.  Within 10 days after the Closing Date,
the Security Instruments and accompanying financing statements covering the
Mortgaged Property requiring filing or recording, or other notices related
thereto if necessary or appropriate, shall have been duly sent for delivery by
the Administrative Agent or its counsel to the appropriate offices for filing
or recording.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

         In order to induce the Lenders to enter into this Agreement, the
Company represents and warrants to the Lenders (which representations and
warranties will survive the delivery of the Notes) that:

         Section 4.01     Existence.  (a) The Company is a limited partnership
duly formed and legally existing under the laws of the State of Texas and is
duly qualified in all jurisdictions wherein the Property owned or the business
transacted by it makes such qualification necessary, except where the failure
to be so qualified would not have a Material Adverse Effect.

         (b)     Each Subsidiary is a corporation duly organized, legally
existing and in good standing under the laws of the jurisdictions in which they
are incorporated and are duly qualified as foreign corporations in all
jurisdictions wherein the Property owned or the business transacted by them
makes such qualifications necessary, except where the failure to be so
qualified would not have a Material Adverse Effect.





                                     -40-
<PAGE>   46
         Section 4.02     Power and Authorization.  The Company is authorized
and empowered to create and issue the Notes; the Company and each of its
Subsidiaries are duly authorized and empowered to execute, deliver and perform
the Financing Documents, including this Agreement, to which they respectively
are parties; and all partnership or corporate action, as the case may be, on
the Company's part requisite for the due creation and issuance of the Notes and
on the Company's and each of its Subsidiaries' respective part requisite for
the due execution, delivery and performance of the Financing Documents,
including this Agreement, to which the Company and each of its Subsidiaries
respectively are parties has been duly and effectively taken.

         Section 4.03     Binding Obligations.  This Agreement does, and the
Notes and other Financing Documents to which the Company and each of its
Subsidiaries respectively are parties upon their creation, issuance, execution
and delivery will, when issued and delivered under this Agreement, constitute
valid and binding obligations of the Company and each such Subsidiary that is a
party thereto, respectively, and will be enforceable in accordance with their
respective terms (except that enforcement may be subject to any applicable
bankruptcy, insolvency or similar laws generally affecting the enforcement of
creditors' rights and subject to the general principles of equity).

         Section 4.04     No Legal Bar or Resultant Lien.  The Notes and the
other Financing Documents, including this Agreement, to which the Company or
any of its Subsidiaries is a party do not and will not violate or create a
default under any provisions of the Partnership Agreement of the Company or the
articles or certificate of incorporation or bylaws or partnership agreements,
as applicable, of the Subsidiaries, or any material contract, agreement,
instrument or Governmental Requirement to which the Company or any of its
Subsidiaries is subject, or result in the creation or imposition of any Lien
upon any Properties of the Company or any of its Subsidiaries, other than those
violations and defaults that would not affect the Company's or such
Subsidiaries' use of such Properties or those permitted by this Agreement.

         Section 4.05     No Consent.  Except as set forth on Schedule 4.05 or
such filings as are required to perfect a Lien securing the Lender
Indebtedness, the Company's and each of its Subsidiaries' respective execution,
delivery and performance of the Notes and the other Financing Documents,
including this Agreement, to which the Company and each such Subsidiary
respectively are parties do not require notice to or filing or registration
with, or the authorization, consent or approval of or other action by any other
Person, including, but not limited to, any Governmental Authority.

         Section 4.06     Financial Information.

                 (a)      Financial Statements.  The audited consolidated
         balance sheet of the Company and its Consolidated Subsidiaries as of
         December 31, 1995, and the related audited consolidated statements of
         income, retained earnings and cash flows for the fiscal year ended on
         such date, and the unaudited consolidated balance sheet of the Company
         and its Consolidated Subsidiaries as of June 30, 1996, and the related
         unaudited consolidated statements of income, retained earnings and
         cash flows for the six-month period then ended, true copies of which
         have been previously delivered to each of the Lenders, fairly present
         the consolidated financial condition of the Company and its
         Consolidated Subsidiaries as at the date thereof and the consolidated
         results of operations for such period, in accordance with GAAP applied
         on a consistent basis.

<PAGE>   47
                 (b)      No Material Adverse Effect.  Since December 31, 1995,
         there has been no event or occurrence that could reasonably be
         expected to have a Material Adverse Effect.

         Section 4.07     Investments and Guaranties.  At the date of this
Agreement, neither the Company nor any of its Subsidiaries has made investments
in or advances to any Person or guaranties of the obligations of any Person
that is not a Subsidiary of the Company, except those permitted by Section
5.03(e), and those reflected in the Financial Statements or described in
Schedule 4.07.

         Section 4.08     Litigation.  Except as set forth in Schedule 4.08,
there is no action, suit or proceeding, or any governmental investigation or
any arbitration, in each case pending or, to the knowledge of the Company,
threatened against the Company or any of its Subsidiaries or any material
Property of any thereof before any court or arbitrator or any Governmental
Authority which (i) challenges the validity of this Agreement, any Note, any
Application, the Guaranty Agreement, or any of the other Financing Documents or
(ii) would reasonably be expected to have a Material Adverse Effect.

         Section 4.09     Federal Reserve Regulations.  Neither the Company nor
any of its Subsidiaries is engaged principally, or as one of its important
activities, in the business of extending credit for the purpose, whether
immediate, incidental or ultimate, of buying or carrying Margin Stock (within
the meaning of Regulation U or X) and no part of the proceeds of any Loan
hereunder will be used to buy or carry any Margin Stock.  Neither the Company
nor any Person acting on behalf of the Company has taken any action which would
cause the Notes or any of the Financing Documents, including this Agreement, to
violate Regulation U or X or any other regulation of the Board of Governors of
the Federal Reserve System or to violate Section 7 of the Securities and
Exchange Act of 1934, as amended, (or any successor thereto) or any rule or
regulation thereunder, in each case as now in effect or as the same may
hereinafter be in effect.

         Section 4.10     Compliance with ERISA.  Neither the Company, any of
its Subsidiaries nor any ERISA Affiliate sponsors, maintains or contributes to,
or has at any time in the six-year period preceding the date of this Agreement
sponsored, maintained or contributed to, any Plan, including, but not limited
to, any Plan which is a "multi-employer plan" as such term is defined in
Section 3(37) or 4001(a)(3) of ERISA.  Except as set forth in Schedule 4.10,
each Plan described in such schedule has been terminated with no resulting
liability to the PBGC.  No act, omission or transaction has occurred which
could result in imposition on the Company, any of its Subsidiaries or any ERISA
Affiliate (whether directly or directly) of (i) either a civil penalty assessed
pursuant to Sections 502(c) or 502(i) of ERISA or a tax imposed pursuant to
Section 4975 of the Code, or (ii) breach of fiduciary duty liability damages
under Section 409 of ERISA, which in each case would have a Material Adverse
Effect.

         Section 4.11     Taxes; Governmental Charges.  The Company and its
Subsidiaries have filed all tax returns and reports required to be filed and
have paid all material taxes, assessments, fees and other governmental charges
levied upon any of them or upon any of their respective Properties or income
which are due and payable, including interest and penalties, or have provided
adequate reserves for the payment thereof if required in accordance with GAAP
for the payment thereof, except such interest and penalties as are being
contested in good faith by appropriate actions or proceedings and for which
adequate reserves for the payment thereof as required by GAAP have been
provided.

         Section 4.12     Title and Liens.  The most recently delivered Reserve
Report reflects, without material error, the aggregate net revenue interest of
the Company and its Subsidiaries in each property





                                     -42-
<PAGE>   48
reported on therein and the aggregate share of the operating expenses
applicable to each such property for which the Company and its Subsidiaries are
liable.  The Company and its Subsidiaries have indefeasible title to such
properties, in accordance with customary standards in the oil and gas business
in the relevant area of operations, subject only to defects and irregularities
which do not materially and adversely affect the value of such properties or
the ability of the Company to possess and sell the production therefrom.  Such
properties are not subject to any Liens other than those permitted under this
Agreement or the other Financing Documents.

         Section 4.13     Defaults.  Neither the Company nor any of its
Subsidiaries is in default nor has any event or circumstance occurred which,
but for the passage of time or the giving of notice, or both, would constitute
a default under any loan or credit agreement, indenture, mortgage, deed of
trust, security agreement or other instrument or agreement evidencing or
pertaining to any Indebtedness of the Company or any of its Subsidiaries, or
under any material agreement or instrument to which the Company or any of its
Subsidiaries is a party or by which the Company or any of its Subsidiaries is
bound, except as disclosed to the Lenders in Schedule 4.13 or except for those
defaults which would not reasonably be expected to have a material adverse
effect.  No Default hereunder has occurred and is continuing.

         Section 4.14     Casualties; Taking of Properties.  Since the date of
the Financial Statements, neither the business nor the Properties of the
Company or any of its Subsidiaries have been affected in a manner that has had
or would reasonably be expected to have a Material Adverse Effect as a result
of any fire, explosion, earthquake, flood, drought, windstorm, accident, strike
or other labor disturbance, embargo, requisition or taking of Property or
cancellation of contracts, permits or concessions by any domestic or foreign
government or any agency thereof, riot, activities of armed forces or acts of
God or of any public enemy.

         Section 4.15     Compliance with the Law.  Neither the Company nor any
of its Subsidiaries:

                 (a)      is in violation of any Governmental Requirement; or

                 (b)      has failed to obtain any license, permit, franchise
         or other governmental authorization necessary to the ownership of any
         of their respective Properties or the conduct of their respective
         business;

which violation or failure would reasonably be expected to have a Material
Adverse Effect.

         Section 4.16     No Material Misstatements.  No information, exhibit
or report furnished to the Administrative Agent or the Lenders by or at the
direction of the Company or any of its Subsidiaries in connection with the
negotiation of this Agreement, when such statement is considered with all other
written statements furnished to the Lenders in that connection, contained any
material misstatement of fact or omitted to state a material fact or any fact
necessary to make the statement contained therein not misleading.

         Section 4.17     Investment Company Act.  The Company is not an
"investment company" or a company "controlled" by an "investment company" that
is incorporated in or organized under the laws of the United States or any
"State," as those terms are defined in the Investment Company Act of 1940, as
amended.  The execution and delivery by the Company and its Subsidiaries of
this Agreement and the other Financing Documents to which they respectively are
parties and their respective performance of the





                                     -43-
<PAGE>   49
obligations provided for therein, will not result in a violation of the
Investment Company Act of 1940, as amended.

         Section 4.18     Public Utility Holding Company Act.  The Company is
not a "holding company," or a "subsidiary company" of a "holding company," or
an "affiliate" of a "holding company" or of a "subsidiary company" of a
"holding company," or a "public-utility company" within the meaning of the
Public Utility Holding Company Act of 1935, as amended.

         Section 4.19     Subsidiaries.  The Company has no Subsidiaries except
those shown in Exhibit B hereto, which exhibit is complete and accurate.  The
Company owns 100% of all stock of the Subsidiaries listed in such Exhibit.

         Section 4.20     Insurance.  Schedule 4.20 attached hereto contains an
accurate and complete description of all material policies of fire, liability,
workmen's compensation, casualty, flood and other forms of insurance owned or
held by the Company and each of its Subsidiaries as of the Closing Date.  All
such policies are in full force and effect, all premiums with respect thereto
have been paid in accordance with their respective terms, and no notice of
cancellation or termination has been received with respect to any such policy.
Such policies are sufficient for compliance with all requirements of law and of
all agreements to which the Company or any of its Subsidiaries is a party; are
valid, outstanding and enforceable policies; provide adequate insurance
coverage in at least such amounts and against at least such risks (but
including in any event public liability) as are usually insured against in the
same general area by companies engaged in the same or a similar business for
the assets and operations of the Company and each of its Subsidiaries; and will
not in any way be affected by, or terminate or lapse by reason of, the
transactions contemplated by this Agreement.  Schedule 4.20 identifies all
material risks, if any, which the Company and its Subsidiaries and their
respective Board of Directors or officers have designated as being self
insured.  Neither the Company nor any of its Subsidiaries has been unable to
obtain any insurance with respect to its assets or operations, nor has its
coverage been limited below usual and customary policy limits during the last
three years.

         Section 4.21     Mortgaged Property.  The discounted present value of
the Mortgaged Property constitutes at least 80% of the aggregate discounted
present value (as reasonably determined by the Administrative Agent) of all Oil
and Gas Properties described in and covered by the engineering or other written
reports which have previously been delivered to and relied upon by the Lenders
in connection with this Agreement.  The Company shall have the right to
designate which Oil and Gas Properties shall constitute Mortgaged Properties,
subject to the requirements in the preceding sentence.

         Section 4.22     Gas Imbalances.  Except as disclosed to the
Administrative Agent in Schedule 4.22, or as otherwise disclosed to the
Administrative Agent from time to time in order to be taken into account in
determining the Borrowing Base, there are no gas imbalances, take or pay or
other prepayments owed by the Company in excess of $5,000,000 in the aggregate
with respect to any of the Mortgaged Property (or in the case of any of the
Mortgaged Property operated by a Person other than the Company or its
Subsidiaries, to the best of the Company's knowledge) which would require the
Company or its Subsidiaries to deliver Hydrocarbons produced from any of the
Mortgaged Property at some future time without then or thereafter receiving
full payment therefor.

         Section 4.23     Environmental Matters.

                 (a)      Environmental Laws, etc.  Neither any Property of the
         Company or its Subsidiaries nor the operations conducted thereon
         violate any applicable order of any court or Governmental Authority or
         Environmental Laws, which violation would reasonably be expected to
         have a Material Adverse Effect or which would reasonably be expected
         to result in remedial obligations having a Material Adverse Effect
         assuming disclosure to the applicable Governmental Authority of all
         relevant facts, conditions and circumstances, if any, pertaining to
         the relevant Property.

                 (b)      No Litigation.  Without limitation of Section 4.23(a)
         above, no Property of the Company or its Subsidiaries nor the
         operations currently conducted thereon or by any prior owner or
         operator of such Property or operation, are in violation of or subject
         to any existing, pending or threatened action, suit, investigation,
         inquiry or proceeding by or before any court or Governmental Authority
         or to any remedial obligations under Environmental Laws, which
         violation, action, suit, investigation, inquiry or proceeding would
         reasonably be expected to have a Material Adverse Effect or which
         would reasonably be expected to result in remedial obligations having
         a Material Adverse Effect assuming disclosure to the applicable
         Governmental Authority of all relevant facts, conditions and
         circumstances, if any, pertaining to the relevant Property.

                 (c)      Notices, Permits, etc.  All notices, permits,
         licenses or similar authorizations, if any, required to be obtained or
         filed by the Company or its Subsidiaries in connection with the
         operation or use of any and all Property of the Company or its
         Subsidiaries, including but not limited to past or present treatment,
         storage, disposal or release of a hazardous substance or solid waste
         into the environment, have been duly obtained or filed except to the
         extent the failure to obtain or file such notices, permits, licenses
         or similar authorizations would not reasonably be expected to have a
         Material Adverse Effect or which would not reasonably be expected to
         result in remedial obligations having a Material Adverse Effect
         assuming disclosure to the applicable Governmental Authority of all
         relevant facts, conditions and circumstances, if any, pertaining to
         the relevant Property.

                 (d)      Hazardous Substances Carriers.  All hazardous
         substances or solid waste generated at any and all Property of the
         Company or its Subsidiaries have in the past been transported, treated
         and disposed of only by carriers maintaining valid permits under RCRA
         and any other Environmental Law, except to the extent the failure to
         have such substances or waste transported, treated or disposed by such
         carriers would not reasonably be expected to have a Material Adverse
         Effect, and only at treatment, storage and disposal facilities
         maintaining valid permits under RCRA and any other Environmental Law,
         which carriers and facilities have been and are operating in
         compliance with such permits, except to the extent the failure to have
         such substances or waste treated, stored or disposed at such
         facilities, or the failure of such carriers or facilities to so
         operate, would not reasonably be expected to have a Material Adverse
         Effect or which would reasonably be expected to result in remedial
         obligations having a Material Adverse Effect assuming disclosure to
         the applicable Governmental Authority of all relevant facts,
         conditions and circumstances, if any, pertaining to the relevant
         Property.





                                     -45-
<PAGE>   51
                 (e)      Hazardous Substances Disposal.  The Company and its
         Subsidiaries have taken all reasonable steps necessary to determine
         and have determined that no hazardous substances or solid waste have
         been disposed of or otherwise released and there has been no
         threatened release of any hazardous substances on or to any Property
         of the Company or its Subsidiaries except in compliance with
         Environmental Laws, except to the extent the failure to do so would
         not reasonably be expected to have a Material Adverse Effect or which
         would not reasonably be expected to result in remedial obligations
         having a Material Adverse Effect assuming disclosure to the applicable
         Governmental Authority of all relevant facts, conditions and
         circumstances, if any, pertaining to the relevant Property.

                 (f)      OPA Requirements.  Except to the extent the failure
         to so comply would not have a Material Adverse Effect, to the extent
         applicable, the Company and its Subsidiaries have complied with all
         design, operation and equipment requirements imposed by OPA or
         scheduled to be imposed by OPA during the term of this Agreement, and
         the Company does not have reason to believe that either it or its
         Subsidiaries will not be able to maintain such compliance with OPA
         requirements during the term of this Agreement.

                 (g)      No Contingent Liability.  The Company and its
         Subsidiaries have no material contingent liability in connection with
         any release or threatened release of any hazardous substance or solid
         waste into the environment which at any one time and from time to time
         would reasonably be expected to exceed by more than $5,000,000
         applicable insurance coverage, indemnities, or the reserves for the
         payment thereof which have been established as required by GAAP, or
         which would reasonably be expected to result in remedial obligations
         having a Material Adverse Effect assuming disclosure to the applicable
         Governmental Authority of all relevant facts, conditions and
         circumstances, if any, pertaining to such release or threatened
         release.

                                   ARTICLE V

                                   COVENANTS

         Section 5.01     Certain Affirmative Covenants.  So long as any Lender
has any Commitment hereunder or any Loan remains unpaid or any Credit Exposure
remains outstanding, the Company will at all times comply with the following
covenants:

                 (a)      Maintenance and Compliance, etc.  The Company will
         and will cause each of its Subsidiaries to (i) except as permitted by
         Section 5.03(c), preserve and maintain its partnership or corporate,
         as the case may be, existence, rights and franchises, and (ii) observe
         and comply in all material respects with all Governmental
         Requirements, except where failure to do so could not reasonably be

         such operators and are beyond the control of the Company or such

         pay, and will cause each of its Subsidiaries to pay before or when due
         the amount owed for the time charter of any tanker or barge used to
         transport feedstocks, blendstocks or refined products, unless in each
         case, the validity or amount thereof is being contested in good faith
         by appropriate action or proceedings and the Company has established
         appropriate reserves in accordance with GAAP.

                 become an ERISA Affiliate with respect to the Company or a
                 Subsidiary of the Company or with respect to any ERISA
                 Affiliate of the Company or a Subsidiary of the Company if
                 such Person sponsors, maintains or contributes to, or at any
                 time in the six-year period preceding such acquisition has
                 sponsored, maintained, or contributed to, (1) any
                 "multi-employer plan" as such term is defined in Section 3(37)

                 to Title IV of ERISA under which the actuarial present value
                 of the benefit liabilities under such Plan exceeds the current
                 value of the assets (computed on a plan termination basis in
                 accordance with Title IV of ERISA) of such Plan allocable to

                 ERISA Affiliate is required to provide security to such Plan 
                 under Section 401(a)(29) of the Code.

                 (j)      Proceeds of Loans.  Use any proceeds of the Loans for
         any purpose other than (i) to renew, rearrange and modify the
         outstanding principal balance owing under the Prior Notes, (ii) to
         acquire proven oil and gas properties, development of oil and gas

         outstanding Loan balance to exceed $35,000,000 for any purpose other
         than the consummation of such acquisition.  The Letters of Credit
         shall be used only for the purposes provided in Section 2.03.  Neither
         the Company nor any Person acting on behalf of the Company will take
         any action which might cause the Notes or any of the Financing
         Documents, including this Agreement, to violate Regulation U or X or
         any other regulation of the Board of Governors of the Federal Reserve
         System or to violate Section 7 of the Securities and Exchange Act of
         1934, as amended, (or any successor thereto) or any rule or regulation
         thereunder, in each case as now in effect or as the same may
         hereinafter be in effect.

                 (k)      Transactions with Affiliates.  Except as otherwise
         permitted in the this Agreement, enter into any transaction or series
         of transactions, or permit any of its Subsidiaries to enter into any
         transaction or series of transactions, with Affiliates of the Company
         or its Subsidiaries (other than the Parent and its Subsidiaries) which
         involve an outflow of money or other Property from the Company or its
         Subsidiaries to an Affiliate of the Company or its Subsidiaries,
         including but not limited to repayment of Indebtedness, management
         fees, compensation, salaries, asset purchase payments or any other
         type of fees or payments similar in nature, other than on terms and
         conditions substantially as favorable to the Company and its
         Subsidiaries as would be obtainable by the Company and its
         Subsidiaries in a reasonably comparable arm's-length transaction with
         a Person other than such an Affiliate of the Company or its
         Subsidiaries.  Notwithstanding the foregoing, the restrictions set
         forth in this Section 5.03(k) shall not apply to the payment of
         reasonable and customary fees to directors of Parent who are not
         employees of Parent or to the payment of reasonable financial advisory
         and similar fees to equity investors in the Company, who are not
         employees (specifically including, the fees payable to NGP under its
         existing agreement with the Company and fees payable to First Union
         Capital Partners and Enron Capital & Trade Resources Corp., or any of
         their respective Affiliates or designees).

                 (l)      Unconditional Purchase Obligations.  Enter into or be
         a party to, or permit any of its Subsidiaries to enter into or be a
         party to, any contract for the purchase of materials, supplies or
         other property or services, if such contract requires that payment be
         made by it regardless of whether or not delivery is ever made of such
         materials, supplies or other property or services.

                 (m)      Change in Management.  Permit any change in the
         current Chief Executive Officer of either the Parent or General
         Partner.

                 (n)      Creation of Subsidiaries.  Except for joint ventures
         and partnerships entered into in the ordinary course of the Company's
         business, create or permit any Subsidiary to create, any new
         Subsidiaries without prior written notice to the Administrative Agent.

         of (i) consolidated current assets to (ii) consolidated current
         liabilities (excluding current maturities of the Notes) to be less
         than 1.0 to 1.0 at any time.  As used in this Section 5.03(o) "current
         assets" shall mean all assets of a Person which under GAAP would be

         liabilities of a Person which under GAAP would be classified as
         current liabilities.

                 (p)      Debt Coverage Ratio. For the period from and after
         the Closing Date through December 31, 1997, the Company will not
         permit the Debt Ratio as of the end of any fiscal quarter of Parent
         (calculated quarterly at the end of each fiscal quarter) to be greater
         than 4.50 to 1.00.  For the period from and after January 1, 1998,
         through the Maturity Date, the Company will not permit the Debt Ratio
         as of the end of any fiscal quarter of Parent (calculated quarterly at
         the end of each fiscal quarter) to be greater than 3.50 to 1.00.  For
         purposes of this Section 5.03(p), "Debt Ratio" shall mean the ratio of
         (i) Funded Indebtedness of Parent and its Consolidated Subsidiaries at
         the end of each fiscal quarter of Parent, to (ii) EBITDA for the four
         fiscal quarters ending on such date.

                 (q)      Interest Coverage Ratio.  For the period from and
         after the Closing Date through December 31, 1997, the Company will not
         permit the Interest Coverage Ratio as of the end of any fiscal quarter
         of Parent (calculated quarterly at the end of each fiscal quarter) to
         be less than 2.50 to 1.00.  For the period from and after January 1,
         1998, through the Maturity Date, the Company will not permit the
         Interest Coverage Ratio as of the end of any fiscal quarter of Parent
         (calculated quarterly at the end of each fiscal quarter) to be less
         than 3.00 to 1.00.  For the purposes of this Section 5.03(q),
         "Interest Coverage Ratio" shall mean the ratio of (i) EBITDA for the
         four fiscal quarters ending on such date to (ii) cash interest
         payments made for such four fiscal quarters of Parent and its
         Consolidated Subsidiaries.

                 (r)      Amendments to Partnership Agreement.  Amend
         materially or restate, or permit any material amendment or restatement
         of, the Partnership Agreement without the prior written consent of the
         Majority Lenders (which consent will not be unreasonably withheld);
         provided, however, the Partnership Agreement may be amended to
         substitute the limited partner of the Company with a wholly-owned
         Subsidiary of the Parent.

                                  ARTICLE VII

                            THE ADMINISTRATIVE AGENT

         Section 7.01     Appointment of Administrative Agent.  Each Lender and
the Issuing Bank hereby designate The Chase Manhattan Bank, as Administrative
Agent to act as herein specified.  Each Lender and the Issuing Bank hereby
irrevocably authorizes the Administrative Agent to take such action on its
behalf under the provisions of this Agreement, the Notes, and the other
Financing Documents and to exercise such powers and to perform such duties
hereunder and thereunder as are specifically delegated to or required of the
Administrative Agent by the terms hereof and thereof and such other powers as
are reasonably incidental thereto.  The Administrative Agent may perform any of
its duties hereunder by or through its agents or employees.

         Section 7.02     Nature of Duties of Administrative Agent.  The
Administrative Agent shall have no duties or responsibilities except those
expressly set forth with respect to the Administrative Agent in this Agreement.
Neither the Administrative Agent, nor any of its respective officers,
directors, employees or agents shall be liable for any action taken or omitted
by it as such hereunder or in connection herewith, unless caused by its or
their gross negligence or willful misconduct.  The duties of the Administrative
Agent shall be mechanical and administrative in nature; the Administrative
Agent shall not have by reason of this Agreement a fiduciary relationship in
respect of any Lender; and nothing in this Agreement, expressed or implied, is
intended to or shall be so construed as to impose upon the Administrative Agent
any obligations in respect of this Agreement except as expressly set forth
herein.

         Section 7.03     Lack of Reliance on the Administrative Agent.

                 (a)      Independent Investigation.  Independently and without
         reliance upon the Administrative Agent, each Lender, to the extent it
         deems appropriate, has made and shall continue to make (i) its own
         independent investigation of the financial condition and affairs of
         the Company in connection with the taking or not taking of any action
         in connection herewith, and (ii) its own appraisal of the
         creditworthiness of the Company, and, except as expressly provided in
         this Agreement, the Administrative Agent shall have no duty or
         responsibility, either initially or on a continuing basis, to provide
         any Lender with any credit or other information with respect





                                     -62-
<PAGE>   68
         thereto, whether coming into its possession before the consummation of
         the transactions contemplated herein or at any time or times
         thereafter.

                 (b)      Administrative Agent Not Responsible.  The
         Administrative Agent shall not be responsible to any Lender or the
         Issuing Bank for any recitals, statements, information,
         representations or warranties herein or in any document, certificate
         or other writing delivered in connection herewith or for the
         execution, effectiveness, genuineness, validity, enforceability,
         collectibility, priority or sufficiency of this Agreement, the Notes,
         the Letters of Credit or the other Financing Documents or the
         financial condition of the Company or be required to make any inquiry
         concerning either the performance or observance of any of the terms,
         provisions or conditions of this Agreement, the Notes or the other
         Financing Documents, or the financial condition of the Company, or the
         existence or possible existence of any Default or Event of Default.

         Section 7.04     Certain Rights of the Administrative Agent.  If the
Administrative Agent shall request instructions from the Majority Lenders with
respect to any act or action (including the failure to act) in connection with
this Agreement, the Notes and the other Financing Documents, the Administrative
Agent shall be entitled to refrain from such act or taking such action unless
and until the Administrative Agent shall have received instructions from the
Majority Lenders; and the Administrative Agent shall not incur liability to any
Person by reason of so refraining.  Without limiting the foregoing, no Lender
shall have any right of action whatsoever against the Administrative Agent as a
result of the Administrative Agent acting or refraining from acting under this
Agreement, the Notes and the other Financing Documents in accordance with the
instructions of the Majority Lenders.

         Section 7.05     Reliance by Administrative Agent.  The Administrative
Agent shall be entitled to rely, and shall be fully protected in relying, upon
any note, writing, resolution, notice, statement, certificate, telex, teletype
or telecopier message, cablegram, radiogram, order or other documentary,
teletransmission or telephone message believed by it to be genuine and correct
and to have been signed, sent or made by the proper Person.  The Administrative
Agent may consult with legal counsel (including counsel for the Company),
independent public accountants and other experts selected by it and shall not
be liable for any action taken or omitted to be taken by it in good faith in
accordance with the advice of such counsel, accountants or experts.

         Section 7.06     INDEMNIFICATION OF ADMINISTRATIVE AGENT.  TO THE
EXTENT THE ADMINISTRATIVE AGENT IS NOT REIMBURSED AND INDEMNIFIED BY THE
COMPANY, EACH LENDER WILL REIMBURSE AND INDEMNIFY THE ADMINISTRATIVE AGENT AS
APPLICABLE, IN PROPORTION TO ITS PERCENTAGE SHARE, FOR AND AGAINST ANY AND ALL
LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS,
SUITS, COSTS, EXPENSES (INCLUDING COUNSEL FEES AND DISBURSEMENTS) OR
DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED ON,
INCURRED BY OR ASSERTED AGAINST THE ADMINISTRATIVE AGENT IN PERFORMING ITS
DUTIES HEREUNDER, IN ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT AND
BY REASON OF ORDINARY NEGLIGENCE OF THE ADMINISTRATIVE AGENT; PROVIDED THAT NO
LENDER SHALL BE LIABLE TO THE ADMINISTRATIVE AGENT FOR ANY PORTION OF SUCH
LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS,
SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING FROM, AS TO THE
ADMINISTRATIVE AGENT, THE ADMINISTRATIVE AGENT'S GROSS NEGLIGENCE OR WILLFUL

         Section 7.07     The Administrative Agent in its Individual Capacity.
With respect to their obligations under this Agreement, the Loans made by it
and the Notes issued to it, the Administrative Agent shall have the same rights
and powers hereunder as any other Lender or holder of a Note and may exercise
the same as though it were not performing the duties, if any, specified herein;
and the terms "Lenders," "Majority Lenders," "holders of Notes" or any similar
terms shall, unless the context clearly otherwise indicates, include the
Administrative Agent in its individual capacity.  The Administrative Agent may
accept deposits from, lend money to, and generally engage in any kind of
banking, trust, financial advisory or other business with the Company or any
affiliate of the Company as if it were not performing the duties, if any,
specified herein, and may accept fees and other consideration from the Company
for services in connection with this Agreement and otherwise without having to
account for the same to the Lenders.

         Section 7.08     May Treat Lender as Owner.  The Administrative Agent
and the Company may deem and treat each Lender as the owner of such Lender's
Note for all purposes hereof unless and until a written notice of the
assignment or transfer thereof shall have been filed with the Administrative
Agent.  Any request, authority or consent of any Person who at the time of
making such request or giving such authority or consent is the owner of a Note
shall be conclusive and binding on any subsequent owner, transferee or assignee
of such Note or any promissory note or notes issued in exchange therefor.

                 (a)      Administrative Agent Resignation.  The Administrative
         Agent may resign at any time by giving written notice thereof to the
         Lenders, the Issuing Bank and the Company and may be removed at any
         time with or without cause by the Majority Lenders.  Upon any such
         resignation or removal, the Majority Lenders shall have the right,
         subject to the reasonable approval of the Company so long as no Event
         of Default then exists, to appoint a successor Administrative Agent.
         If no successor Administrative Agent shall have been so appointed by
         the Majority Lenders, and shall have accepted such appointment, within
         30 days after the retiring Administrative Agent's giving of notice of
         resignation or the Majority Lenders' removal of the retiring
         Administrative Agent, then, upon five days' notice to the Company, the
         retiring Administrative Agent may, on behalf of the Lenders, appoint a
         successor Administrative Agent, which shall be a bank which maintains
         an office in the United States, or a commercial bank organized under
         the laws of the United States of America or of any State thereof, or
         any Affiliate of such bank, having a combined capital and surplus of
         at least $250,000,000.

                 (b)      Rights, Powers, etc.  Upon the acceptance of any
         appointment as Administrative Agent hereunder by a successor
         Administrative Agent, such successor Administrative Agent shall
         thereupon succeed to and become vested with all the rights, powers,
         privileges and duties of the retiring Administrative Agent, and the
         retiring Administrative Agent shall be discharged from its duties and
         obligations under this Agreement.  After any retiring Administrative
         Agent's resignation or removal hereunder as Administrative Agent, the
         provisions of this Article VII shall inure to its benefit as to any
         actions taken or omitted to be taken by it while it was Administrative
         Agent under this Agreement.

                 (b)      Branch Offices, Affiliates.  Any Lender may make,

         Section 8.07     Assignments and Participations.

                 (a)      No Company Assignments.  The Company may not assign
         its rights and obligations hereunder or under the Notes.

                 (b)      Assignment by Lenders.  Each Lender may, upon the
         written consent of the Administrative Agent and, so long as no Event
         of Default exists, the Company (which consents shall not be
         unreasonably withheld), assign to one or more Eligible Transferees all
         or a portion of its rights and obligations under this Agreement
         pursuant to an Assignment and Acceptance Agreement substantially in
         the form of Exhibit D (an "Assignment and Acceptance") provided,
         however, that (i) any such assignment shall be in the aggregate amount
         of at least $10,000,000 or such lesser amount to which the Company has
         consented (or if the aggregate amount of any Lender's Loans and
         Commitments is less than $10,000,000, then the entire amount of such
         Lender's Loans and Commitments), and (ii) the assignee shall pay to
         the Administrative Agent a processing and recordation fee of $2,500.
         Any such assignment will become effective upon the recording by the
         Administrative Agent of such assignment in the Register of the
         resultant effects thereof on the Commitment of the assignor and
         assignee, and the principal amount outstanding of the Loans owed to
         the assignor and assignee, the Administrative Agent hereby agreeing to
         effect such recordation no later than five Business Days after its
         receipt of an Assignment and Acceptance executed by all parties
         thereto.  Promptly after receipt of an Assignment and Acceptance
         executed by all parties thereto, the Administrative Agent shall send
         to the Company a copy of such executed Assignment and Acceptance.
         Upon receipt of such executed Assignment and Acceptance, the Company,
         will, at its own expense, execute and deliver new Notes to the
         assignor and/or assignee, as appropriate, in accordance with their
         respective interests as they appear on the Register, whereupon the
         Administrative Agent shall redeliver the Note being assigned, as
         received from the Assignor, to the Company.  Upon the effectiveness of
         any assignment pursuant to this subsection, the assignee shall be
         deemed automatically to have become a party hereto, if not already a
         party hereto, and shall become a "Lender," if not already a "Lender,"
         for all purposes of this Agreement and the other Financing Documents.
         The assignor shall be relieved of its obligations hereunder to the
         extent of such assignment (and if the assigning Lender no longer holds
         any rights or obligations under this Agreement, such assigning Lender
         shall cease to be a "Lender" hereunder).  The Administrative Agent
         will prepare on the last Business Day of each month during which an
         assignment has become effective pursuant to this subsection a new
         schedule giving effect to all such assignments effected during such
         month, and will promptly provide the same to the Company, the Issuing
         Bank and each of the Lenders.

                 (c)      Participations.  Each Lender may transfer, grant or
         assign participations in all or any part of such Lender's interests
         hereunder pursuant to this subsection to any Person, provided that:
         (i) such Lender shall remain a "Lender" for all purposes of this
         Agreement and the transferee of such participation shall not
         constitute a "Lender" hereunder; and (ii) no participant under any
         such participation shall have rights to approve any amendment to or
         waiver of this Agreement, the Notes or any Financing Document except
         to the extent such amendment or waiver would (x) extend the Maturity
         Date or the Final Maturity Date of any of the Commitments or Loans in
         which such participant is participating, (y) reduce the interest rate
         (other than as a result





                                     -69-

         of waiving the applicability of any post-default increases in interest
         rates) or fees applicable to any of the Commitments or Loans in which
         such participant is participating, or postpone the payment of any
         thereof, or (z) release all or substantially all of the collateral or
         guaranties (except as expressly provided in the Financing Documents)
         supporting any of the Commitments or Loans in which such participant
         is participating.  In the case of any such participation, the
         participant shall not have any rights under this Agreement or any of
         the Financing Documents (the participant's rights against the granting
         Lender in respect of such participation to be those set forth in the
         agreement with such Lender creating such participation), and all
         amounts payable by the Company hereunder shall be determined as if
         such Lender had not sold such participation, provided that such
         participant shall be entitled to receive additional amounts under
         Sections 2.16 and 2.18 on the same basis as if it were a Lender.  In
         addition, each agreement creating any participation must include an
         agreement by the participant to be bound by the provisions of Section
         8.14.  Notwithstanding anything in this Section 8.07(c) to the
         contrary, the purchase by each Lender of a participation in the
         Letters of Credit on the Effective Date and any subsequent assignment
         of all or any part of any such Lender's Percentage Share in any Letter
         of Credit and its related LC Liabilities pursuant to Section 8.07(b)
         shall not be considered a participation pursuant to this Section
         8.07(c).

                 (d)      Registration Statements; Blue Sky Laws.
         Notwithstanding any other provisions of this Section 8.07, no transfer
         or assignment of the interests or obligations of any Lender hereunder
         or any grant of participations therein shall be permitted if such
         transfer, assignment or grant would require the Company or any
         Guarantor to file a registration statement with the Securities and
         Exchange Commission or to qualify the Loans under the "Blue Sky" laws
         of any state.

                 (e)      Certain Representations.  Each Lender initially party
         to this Agreement hereby represents, and each Person that becomes a
         Lender pursuant to an assignment permitted by subsection (b) above
         will, upon its becoming party to this Agreement, represent that it is
         an Eligible Transferee, and that it will make or acquire Loans only
         for its own account in the ordinary course of its business; provided,
         however, that subject to the preceding Sections 8.07(b) through (d),
         the disposition of any promissory notes or other evidences of or
         interests in Lender Indebtedness held by such Lender shall at all
         times be within its exclusive control.

                 (f)      Assignees Treated as Lenders.  The entries in the
         Register shall be conclusive in the absence of manifest error and the
         Company, the Administrative Agent, the Issuing Bank and the Lenders
         may treat each person whose name is recorded in the Register pursuant
         to the terms hereof as a Lender hereunder for all purposes of this
         Agreement and the other Financing Documents.  The Register shall be
         available for inspection by the Company and any Lender, at any
         reasonable time and from time to time upon reasonable prior notice.

                 (g)      Notwithstanding anything in this Section 8.07 to the
         contrary, any Lender may, without the consent of the Company, assign
         and pledge all or any of its Notes to any Federal Reserve Bank or the
         United States Treasury as collateral security pursuant to Regulation A
         of the Board of Governors of the Federal Reserve System and any
         operating circular issued by such Federal Reserve System and/or such
         Federal Reserve Bank.  No such assignment and/or pledge shall release
         the assigning and/or pledging Lender from its obligations hereunder.

         Section 8.08     Governing Law; Submission to Jurisdiction; Etc.

                 (a)      GOVERNING LAW.  THIS AGREEMENT AND THE RIGHTS AND
         OBLIGATIONS OF THE PARTIES HEREUNDER AND UNDER THE NOTES SHALL BE
         CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE
         OF NEW YORK AND TO THE EXTENT CONTROLLING, LAWS OF THE UNITED STATES
         OF AMERICA.

                 (b)      SUBMISSION TO JURISDICTION.  ANY LEGAL ACTION OR
         PROCEEDING WITH RESPECT TO THIS AGREEMENT, THE NOTES OR THE OTHER
         FINANCING DOCUMENTS MAY BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS
         OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF TEXAS,
         AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE COMPANY HEREBY
         ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND
         UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS.  THE
         COMPANY HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, BUT NOT
         LIMITED TO, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE
         GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO
         THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE
         JURISDICTIONS.

                 (c)      Service of Process.  Nothing herein shall affect the
         right of the Administrative Agent or any Lender or any holder of a
         Note to serve process in any other manner permitted by law or to
         commence legal proceedings or otherwise proceed against the Company in
         any other jurisdiction.

         Section 8.09     Independent Nature of Lenders' Rights.  The amounts
payable at any time hereunder to each Lender shall be a separate and
independent debt, and each Lender shall be entitled to protect and enforce its
rights arising out of this Agreement, and it shall not be necessary for any
other Lender to be joined as an additional party in any proceeding for such
purpose.

         Section 8.10     Invalidity.  In the event that any one or more of the
provisions contained in the Notes, this Agreement or in any other Financing
Document shall, for any reason, be held invalid, illegal or unenforceable in
any respect, such invalidity, illegality or unenforceability shall not affect
any other provision of the Notes, this Agreement or any other Financing
Document.

         Section 8.11     Survival of Agreements.  All representations and
warranties of Parent, the Company or its Subsidiaries or any other Person
herein or in the other Financing Documents, and all covenants and agreements
herein not fully performed before the Effective Date, shall survive such date
or dates.

         Section 8.12     Renewal, Extension or Rearrangement.  This Agreement
restates and amends in its entirety, effective as of the Effective Date, the
Prior Credit Agreement.  The Notes are given, in part, to renew, rearrange and
modify the indebtedness heretofore evidenced by the Prior Notes.  Effective as
of the Effective Date, references to the Prior Credit Agreement and the Prior
Notes in the Mortgage and in the other "Financing Documents" referred to in the
Prior Credit Agreement shall refer to this Agreement and to the Notes.  All
provisions of this Agreement and of any other Financing Documents relating to
the Notes or other Lender Indebtedness shall hereafter apply with equal force
and effect to each and all promissory notes hereafter executed which in whole
or in part represent a renewal, extension





                                     -71-
<PAGE>   77
for any period, increase or rearrangement of any part of the Lender
Indebtedness originally represented by the Notes, or of any part of such other
Lender Indebtedness.

         Section 8.13     Interest.  It is the intention of the parties hereto
to conform strictly to usury laws applicable to the Administrative Agent, the
Issuing Bank and the Lenders (collectively, the "Financing Parties") and the
Transactions.  Accordingly, if the Transactions would be usurious as to any
Financing Party under laws applicable to it, then, notwithstanding anything to
the contrary in the Notes, this Agreement or in any other Financing Document or
agreement entered into in connection with the Transactions or as security for
the Notes, it is agreed as follows: (i) the aggregate of all consideration
which constitutes interest under law applicable to any Financing Party that is
contracted for, taken, reserved, charged or received by such Financing Party
under the Notes, this Agreement or under any of such other Financing Documents
or agreements or otherwise in connection with the Transactions shall under no
circumstances exceed the maximum amount allowed by such applicable law, (ii) in
the event that the maturity of the Notes is accelerated for any reason, or in
the event of any required or permitted prepayment, then such consideration that
constitutes interest under law applicable to any Financing Party may never
include more than the maximum amount allowed by such applicable law, and (iii)
excess interest, if any, provided for in this Agreement or otherwise in
connection with the Transactions shall be cancelled automatically by such
Financing Party and, if theretofore paid, shall be credited by such Financing
Party on the principal amount of such Financing Party's Indebtedness (or, to
the extent that the principal amount of such Financing Party's Indebtedness
shall have been or would thereby be paid in full, refunded by such Financing
Party to the Company).  The right to accelerate the maturity of the Notes does
not include the right to accelerate any interest which has not otherwise
accrued on the date of such acceleration, and the Financing Parties do not
intend to collect any unearned interest in the event of acceleration.  All sums
paid or agreed to be paid to the Financing Parties for the use, forbearance or
detention of sums included in the Lender Indebtedness shall, to the extent
permitted by law applicable to such Financing Party, be amortized, prorated,
allocated and spread throughout the full term of the Notes until payment in
full so that the rate or amount of interest on account of the Lender
Indebtedness does not exceed the applicable usury ceiling, if any.  As used in
this Section, the terms "applicable law" or "laws applicable to any Financing
Party" means the law of any jurisdiction whose laws may be mandatorily
applicable notwithstanding other provisions of this Agreement, or law of the
United States of America applicable to any Financing Party and the Transactions
which would permit such Financing Party to contract for, charge, take, reserve
or receive a greater amount of interest than under such jurisdiction's law.  To
the extent that Article 5069-1.04 of the Texas Revised Civil Statutes is
relevant to any Financing Party for the purpose of determining the Highest
Lawful Rate, such Financing Party hereby elects to determine the applicable
rate ceiling under such Article by the indicated (weekly) rate ceiling from
time to time in effect, subject to such Financing Party's right subsequently to
change such method in accordance with applicable law.

         Section 8.14     Confidential Information.  The Administrative Agent
and each Lender agree that all documentation and other information made
available by the Company to the Administrative Agent or such Lender under the
terms of this Agreement shall (except to the extent such documentation or other
information is publicly available or hereafter becomes publicly available other
than by action of the Administrative Agent or such Lender, or was theretofore
known or hereinafter becomes known to the Administrative Agent or such Lender
independent of any disclosure thereto by the Company) be held in the strictest
confidence by the Administrative Agent or such Lender and used solely in the
administration and enforcement of the Loans from time to time outstanding from
such Lender to the Company and in the prosecution of defense of legal
proceedings arising in connection herewith; provided that (i) the





                                     -72-
<PAGE>   78
Administrative Agent or such Lender may disclose documentation and information
to the Administrative Agent and/or to any other Lender which is a party to this
Agreement or any Affiliates thereof and (ii) the Administrative Agent or such
Lender may disclose such documentation or other information to any other bank
or other Person to which such Lender sells or proposes to make an assignment or
sell a participation in its Loans hereunder if such other bank or Person, prior
to such disclosure, agrees in writing to be bound by the terms of the
confidentiality statement customarily employed by the Administrative Agent in
connection with such potential transfers.  Notwithstanding the foregoing,
nothing contained herein shall be construed to prevent the Administrative Agent
or a Lender from (a) making disclosure of any information (i) if required to do
so by applicable law or regulation or accepted banking practice, (ii) to any
governmental agency or regulatory body having or claiming to have authority to
regulate or oversee any aspect of such Lender's business or that of such
Lender's corporate parent or affiliates in connection with the exercise of such
authority or claimed authority, (iii) pursuant to any subpoena or if otherwise
compelled in connection with any litigation or administrative proceeding, (iv)
to correct any false or misleading information which may become public
concerning such Person's relationship to the Company, or (v) to the extent the
Administrative Agent or such Lender or its counsel deems necessary or
appropriate to effect or preserve its security for any Lender Indebtedness or
to enforce any remedy provided in the Financing Documents, the Notes or this
Agreement or otherwise available by law; or (b) making, on a confidential
basis, such disclosures as such Lender reasonably deems necessary or
appropriate to its legal counsel or accountants (including outside auditors).
If the Administrative Agent or such Lender is compelled to disclose such
confidential information in a proceeding requesting such disclosure, the
Administrative Agent or such Lender shall seek to obtain assurance that such
confidential treatment will be accorded such information; provided, however,
that the Lender shall have no liability for the failure to obtain such
treatment.

         Section 8.15     ENTIRE AGREEMENT.  THE NOTES, THIS AGREEMENT AND THE
OTHER FINANCING DOCUMENTS EMBODY THE ENTIRE AGREEMENT AND UNDERSTANDING BETWEEN
THE ADMINISTRATIVE AGENT, THE ISSUING BANK OR THE LENDERS AND THE OTHER
RESPECTIVE PARTIES HERETO AND THERETO AND SUPERSEDE ALL PRIOR AGREEMENTS AND

         Section 8.17     Counterparts.  This Agreement may be executed in any
number of counterparts and by the different parties hereto on separate
counterparts, each of which when so executed and delivered shall be an original
but all of which shall together constitute one and the same instrument.

         Section 8.18     Survival of Indemnities.  The Company's obligations
under Sections 2.16, 2.18, 2.21 and 8.04 shall survive the payment in full of
the Loans and the LC Liabilities.

         Section 8.19     Headings Descriptive.  The headings of the several
sections and subsections of this Agreement, and the Table of Contents, are

determination of such satisfaction shall be made by such party in its sole and
exclusive judgment exercised reasonably and in good faith.

Agent in the State of Texas and accepted by the Administrative Agent in such
