ITEM 1.  BUSINESS

This Report on Form 10-K contains statements that are considered 
"forward-looking statements," as defined in the Private Securities Litigation
Reform Act of 1995 and as described under "-Forward-Looking Statements" in this
Item 1 -"BUSINESS." Actual results may differ materially from those contemplated
by the forward-looking statements herein.

Certain oil and gas terms and abbreviations are defined in this Item 1 under
"-BUSINESS" - Definitions of Certain Oil and Gas Terms."

BACKGROUND

Venus Exploration, Inc. (collectively with its consolidated subsidiaries, unless
the context otherwise requires, "Venus" or the "Company") is engaged primarily
in the application of advanced geoscience technology to the exploration for
undiscovered onshore oil and gas reserves in the United States. The Company also
is actively involved in exploitation and/or development of existing oil and gas
fields and is actively seeking acquisitions of producing properties. The Company
presently has oil and gas properties, acreage and production in ten states.
Since the May 21, 1997 transactions discussed below, the Company's emphasis has
been on oil and gas exploration and development projects and prospects in Texas,
Oklahoma and Kansas. The Company was incorporated in the State of Delaware in
September 1985. The management of Venus has been involved as a privately held
independent oil and gas operator in the development and exploitation of several
large oil and gas fields.

The predecessor to Venus started in May 1996, and its primary assets were an
inventory of exploration Prospects and Prospect Leads and undeveloped producing
oil and gas fields with very little oil and gas production. In 1997, average
daily net production increased to 2,450 Mcfe/day from 565 Mcfe/day in 1996, a
333% increase. The total Proved Reserves increased from 2.8 Bcfe at year end
1996 to 12.4 Bcfe in 1997, or 343%, as a result of the reverse merger
transaction described below and as a result of the 1997 drilling program.
Approximately 52.5 % of the Company's reserves are natural gas reserves. Venus
operates 81% of its Net Wells.

1997 BUSINESS COMBINATION AND PROPERTY ACQUISITION

On May 21, 1997, the Company (then known as "Xplor Corporation") acquired
substantially all of the assets and liabilities of The New Venus Exploration,
Inc., a privately-held Texas corporation ("New Venus"), in exchange for
5,626,473 shares of the Company's Common Stock, par value $0.01 per share (the
"Common Stock"), and warrants to purchase an additional 272,353 shares of Common
Stock exercisable at $3.00 per share until October 23, 2000 ("Acquisition
Warrants"). Simultaneously, the Company acquired certain oil and gas properties
from Lomak Petroleum, Inc. ("Lomak") in exchange for 2,037,171 shares of the
Company's Common Stock and Acquisition Warrants to purchase an additional
272,353 shares of Common Stock. At the same time, Lomak acquired from an
existing stockholder of the Company 97,008 shares of Common Stock. These
transactions were completed in accordance with the Property Acquisition
Agreement dated April 29, 1997, and related agreements (collectively, the
"Acquisition Agreement"). As a result of these transactions (collectively, the
"Acquisition"), the former stockholders of New Venus acquired, as of the
effective date of the Acquisition, 58% of the Company's outstanding Common
Stock, and Lomak acquired 22%, while the preexisting stockholders of the Company
then owned 20% of the Common Stock.

The Acquisition Agreement provided, among other things, that the Board of
Directors of the Company be composed of four directors nominated by New Venus,
one director nominated by Lomak and two continuing directors of the Company. At
the consummation of the Acquisition, a stockholders agreement (the "Stockholders
Agreement") was entered into among certain former stockholders of New Venus
(collectively, the "Ames Group," which owns beneficially 3,721,600 shares of the
Company's Common Stock), certain major shareholders of the Company (collectively
the "Blair Group," which owns beneficially 1,066,512 shares) and Lomak. The
Stockholders Agreement provided that at the 1997 election of directors of the
Company, the Ames Group, the Blair Group and Lomak would vote their shares of
the 


                                      -1-
<PAGE>   5

Company for the four nominees designated by the Ames Group, the two nominees
designated by the Blair Group, and the one nominee designated by Lomak. The
Blair Group's right to designate two nominees is reduced to the right to
designate one nominee effective with the 1998 Annual Meeting of Stockholders of
the Company and ceases altogether effective with the 1999 Annual Meeting of
Stockholders. The Stockholders Agreement also provides for certain rights of
first refusal and rights of participation between the Ames Group and Lomak in
the event of a proposed sale of shares by either. The Stockholders Agreement has
a term of three years, but it terminates earlier as to any party in the event
that such party's beneficial ownership of the Company's Common Stock falls below
250,000 shares.

For accounting purposes, the Acquisition was treated as a reverse acquisition
with New Venus being deemed to have acquired the assets of Xplor Corporation and
the Lomak entities. Therefore, unless otherwise stated all accounting and other
operating data for periods before May 21, 1997, in this Annual Report on Form
10-K are data of New Venus and its predecessors, none of which had previously
been publicly reported. Information after that date reflects the operations of
the combined entities and acquired properties.

BUSINESS STRATEGY

As a result of the Acquisition, the Company adopted the growth strategy
previously practiced by the privately-held New Venus. Venus is now actively
pursuing an aggressive growth strategy of (i) exploration for oil and gas
reserves, (ii) exploitation and development drilling in existing oil and gas
fields, and (iii) strategic acquisition of producing properties with upside
potential. During 1997 and the first quarter of 1998, Venus participated in the
drilling of 5 Gross (2.3 Net) Exploratory Wells, of which 4 Gross (2 Net) Wells
were completed as producers and 1 Gross (0.3 Net) Well was a dry hole. The
Company also participated in the drilling of 10 Gross (6 Net) Development Wells.
As of March 25, 1998, eight Gross (5 Net) of those wells have been completed as
producers and two Gross (1 Net) Wells were awaiting final completion.

EXPLORATION - Exploration for oil and gas reserves and the generation of
drilling prospects in areas identified through the application of advanced
geoscience technology by the Company's exploration team provide the Company with
exposure to opportunities for the discovery of new oil and gas reserves and
rapid growth in asset values. Because of the inherent uncertainty and high
financial risk associated with the outcome of individual drilling prospects, the
Company attempts to maintain an inventory of many exploratory Prospect Leads
from which drilling prospects are confirmed and generated. This strategy has
been used successfully in the past by the Company's management.

The Company's exploration team currently concentrates on two primary
geographical focus areas; the south Midland Basin in West Texas and the Yegua
Trend of the Texas and Louisiana Gulf Coast. Other focus areas are under
consideration. An inventory of more than 40 Prospects and Prospect Leads is
currently being worked. The Company utilizes 2-D Seismic and 3-D Seismic data in
combination with advanced geological concepts to evaluate these Prospects and
Prospect Leads. The Company's in-house technical capability is an important
ingredient in the Company's current and continuing ability to conduct
comprehensive exploration programs and to continue to generate exploratory
prospects with merit.

EXPLOITATION AND DEVELOPMENT OF PRODUCING FIELDS - In addition to exploring for
new oil and gas reserves in previously undiscovered fields, the Company also
utilizes advanced geoscience technology to exploit and to develop oil and gas
reserves in currently producing fields. The fields being exploited or developed
consist of fields discovered by the Company or fields discovered by others but
that the Company believes are not fully developed. Venus is conducting active
exploitation and development activities in eleven different fields in Texas,
Oklahoma and Kansas. The Company's working interest in the fields being
developed varies in size from 2.5% to 100%, and Venus operates nine of the
eleven active fields.

<PAGE>   6
ACQUISITIONS, STRATEGIC ALLIANCES & DIVESTITURES OF SELECTED PROPERTIES - Venus
will continue to seek strategic producing property acquisitions that offer
near-term production and longer-term development and exploration opportunities
that can be investigated through the application of advanced technology by the
Company's exploration team. The Company also seeks to accomplish strategic
acquisitions of producing assets with development and exploratory potential
through strategic alliances with other oil and gas companies. Venus may also
sell non-strategic properties as a part of its effort to concentrate on its
focus areas.

RECENT DEVELOPMENTS (SINCE DECEMBER 31, 1997) -

Preliminary results from drilling activities in the first quarter of 1998 are
shown below. All of the six wells described below are also included in drilling
summary given in the first paragraph of the "-Business Strategy" immediately
above. Caution should be taken when considering these results because they are
not supported by production histories. Test results typically exceed, often by
large amounts, production output once a well has produced for some period of
time. In addition, test results often exceed state-mandated field allowables for
production.

         (i)      Culley #2 Well. Allen Field, Seminole County, Oklahoma. The
                  Company owns a 100% Working Interest in this well, which was a
                  discovery well in a new pay zone of the second Wilcox
                  formation between the depths of 4139 and 4142 feet subsurface.
                  The well's initial production test produced 297 Bbls in 23.5
                  hours.

         (ii)     Westbury Farms #1 Well. Constitution Field, Jefferson County,
                  Texas. The Company owns a 15% Working Interest in this well,
                  which was completed in a sand formation at a depth of
                  approximately 14,000 feet subsurface. The well's initial
                  production test produced 2050 Mcf/day and 357 Bbls of
                  condensate on a 15/64" choke with a flowing tubing pressure of
                  2289 psig.

         (iii)    Smith #3 Well. Fashing Field, Atascosa County, Texas. The
                  Company owns an 84.2% Working Interest in this well, which was
                  completed in the Edwards "A" Limestone at a depth between
                  10,654 and 10,725 feet subsurface. The well's initial
                  production test produced 440 Mcf/day and 13.8 Bbls on a 20/64"
                  choke with a flowing tubing pressure of 290 psig.

         (iv)     Duson #1 Well. Hutchins-Kubela (Frio) Field, Wharton County,
                  Texas. The Company owns a 22.15% Working Interest in this
                  well, which was plugged back from the Yegua formation and was
                  completed in the Frio sandstone at a depth between 4888 and
                  4891 feet subsurface. The well's initial production test
                  produced 658 Mcf/day on a 9/64" choke with a flowing tubing
                  pressure of 1761 psig.

         (v)      Simonson #25-1 Well. Wildcat, Seward County, Kansas. The
                  Company owns a 50% Working Interest in this well, which was
                  unsuccessfully completed in the Arbuckle formation. Current
                  plans are to attempt another completion in another formation.

         (vi)     Brown #26-1 Well. Wildcat, Seward County, Kansas. The Company
                  owns a 50% Working Interest in this well, which was
                  unsuccessfully completed in the Osage formation. Current plans
                  are to attempt another completion in another formation.

FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K contains forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934. Those statements are contained under this Item
1 "-Business," under Item 7 "-Management's Discussion and Analysis of Financial
Condition and Results of Operations," and elsewhere in this Form 10-K. The
forward-looking statements are identified by language that speaks of future
events; e.g., words such as "may," "could," "believe," "expect," "intend,"
"anticipate," "estimate," "continue," "projected," "future," "will," "seek," and
"plan". The forward-looking statements address such matters as geological
estimates of oil and gas reserves, exploratory and development drilling plans
and schedules, capital expenditures, availability of capital resources,
financial projections, present values of future production, financing
assumptions and other statements that are not historical facts. Although
statements involving those matters are based on information available at the
time this Annual Report on Form 10-K was prepared and although Venus believes
that its statements are based on reasonable assumptions, it can give no
assurance that its goals will be achieved or that the level of production or
financial return expected can be achieved. Some of the important factors that
could cause actual results to differ materially from those predicted in the
forward-looking statements include (i) state and federal regulatory developments
and statutory changes, (ii) the timing and extent of changes in commodity prices
and markets, (iii) the timing and extent of success in acquiring leasehold
interests and in discovering, developing or acquiring oil and gas reserves, (iv)
the conditions of the capital and equity markets during the periods covered by
the forward-looking statements, (v) reliance on estimates of reserves, (vi)
drilling results, and (vii) other matters beyond the control of the Company;
e.g., the risk factors listed below.

RISK FACTORS

CAPITAL EXPENDITURES AND AVAILABILITY OF FINANCING - The implementation of
Venus's business strategy will require substantial new capital on a continuing
basis. Expected cash flow from existing properties will be insufficient to fund
the projects planned by the Company. Venus plans to address its long-term
liquidity and capital needs through bank financing, the issuance of debt and
equity securities, when market conditions permit, and through the use of
non-recourse production-based financing. Venus also continues to examine
alternative sources of long-term capital; e.g., the sale of net profits
interest, sales of non-strategic properties, prospects and technical
information, and joint venture financing. The amount and timing of Venus's
future capital requirements, if any, will depend upon a number of factors,
including drilling costs, transportation costs, equipment costs, marketing
expenses, staffing levels and competitive conditions, many, if not all, of which
are beyond Venus's control. Availability of these sources of capital and,
therefore, the Company's ability to execute its business plan will depend upon a
number of factors, many of which are beyond the control of the Company. Failure
to obtain such financing could materially and adversely affect Venus's growth,
cash flow and earnings.

COMPETITION - The oil and gas industry is highly competitive in all of its
phases and in particular in the acquisition of unexplored acreage, undeveloped
acreage and existing production. There are a large number of operators engaged
in oil and gas property acquisition and development, and Venus's competitive
position depends on its geological, geophyisical and engineering expertise, on
its financial resources and on its ability to find, to acquire and to prove new
oil and gas reserves. The Company encounters strong competition in acquiring
economically desirable properties and in obtaining equipment and labor to
operate and to maintain its properties. That competition is from major and
independent oil and gas companies, many of which possess greater financial
resources and larger staffs than Venus. Labor and equipment markets have shown
much volatility recently, and no assurance can be given as to their availability
at the prices budgeted by Venus.

<PAGE>   8
ACQUISITION RISKS - Venus intends to acquire producing oil and natural gas
properties. Any such acquisition will be on the basis of an evaluation of the
value of recoverable reserves associated with that property. Venus intends to
use reasonable efforts to assess the value of potential acquisitions, but it may
not have all the relevant facts because it is often not feasible to review in
detail every oil and gas lease or aspect of an acquisition. Furthermore, even a
detailed review may miss important facts; e.g., mechanical integrity of
equipment and environmental liability that is not obvious from a surface
inspection. For these and other reasons, there can be no assurance that oil and
natural gas properties acquired by Venus will be successfully integrated into
its operations or will achieve desired or projected profitability objectives.

DRILLING RISKS - Venus's drilling plans involve numerous risks; e.g., unexpected
costs and conditions attributable to overpressure in formations, equipment
failures and accidents, weather conditions, shortages or delays in obtaining
equipment and labor shortages. Some wells are dry holes and will return nothing
on the capital invested in those wells. Some wells are completed, but they do
not produce enough to repay the investment in pre-drilling, drilling and/or
operating expenses. Regardless of these factors and others or the success of a
well, Venus will incur the expenses attributable to those risks, and that may
affect its ability to work on other properties. There can be no assurance of
success or profitability of future drilling activities.

MARKETS - The availability of a ready market for any oil and gas produced by the
Company and the opportunities to find and to develop new oil and gas reserves
depends upon numerous factors beyond its control, the exact effect of which
cannot be accurately predicted. These factors include federal and state
regulatory developments and statutory enactments, the timing and extent of
changes in commodity prices, exploratory and development drilling success, the
amount of oil and gas available for sale, availability of professional expertise
and operating personnel, crude oil imports, access to adequate capital, the
availability of adequate pipeline and other transportation facilities, the
marketing of competitive fuels and other matters affecting the availability of a
ready market such as fluctuating supply and demand.

VOLATILITY OF PRICES - Venus's revenues, profitability and future rate of
growth, if any, are substantially dependent upon the prevailing prices for oil
and gas. Historically, the prices for oil and gas have been highly volatile.
This volatility is based on factors largely beyond the control of the Company.
For example, prices are affected by weather, actions of foreign and domestic
governments, international cartels and domestic and world economic conditions.
Any substantial or extended decline in prices like those experienced in the
first three months of 1998 would have a material adverse effect on Venus's
financial conditions and results of operations.

ESTIMATION OF RESERVES - The reserve data presented in this Annual Report on
Form 10-K are present estimates only. In general, estimates of reserves and the
future net revenues from those reserves are based on a number of variable
factors and subjective assumptions, such as historical production from the
properties, the assumed effects of government regulation of future production,
and assumptions about future oil and gas prices and future operating costs.
Future projections based on such factors and assumptions may, and likely will,
vary considerably from actual results.

REPLACEMENT OF RESERVES - The volume of production from oil and gas properties
usually declines as they are produced and the reserves are depleted. The decline
rates depend on reservoir characteristics and vary from steep decline curves to
the relatively slow declines of some properties such as the Company's gas
reserves in West Virginia. Unless Venus finds new reserves through its
exploration and development activities or it acquires properties containing
Proved Reserves, or both, the Proved Reserves of the Company will decline as
reserves are produced. Venus's future natural gas and oil production is,
therefore, highly dependent upon its level of success in finding or acquiring
additional reserves. To the extent that the Company is unsuccessful in replacing
depleted reserves and otherwise enlarging them, the Company's revenues will
decline over time.


                                      -5-
<PAGE>   9
REGULATION OF PRODUCTION - Production of any oil and gas discovered or acquired
by the Company is affected to some degree by state and federal laws and
regulations. Many states have statutory provisions regulating the production and
sale of oil and gas, including provisions regarding deliverability. Other states
require drilling bonds, various permits related to drilling operations, and
operational reports. Such statutes, and the regulations promulgated in
connection therewith, are generally intended to prevent waste and to protect the
correlative rights of owners in a common reservoir to produce oil and gas from
that reservoir. Certain state regulatory authorities also regulate the amount of
oil and gas produced by assigning allowable rates of production to each well or
proration unit, and those allowable rates may increase or decrease in accordance
with supply and demand.

ENVIRONMENTAL REGULATION - The federal government and various state and local
governments have adopted laws and regulations regarding the control of
contamination of the environment. These laws and regulations are often changed,
and the scope of coverage enlarged. The current laws and regulations may require
the acquisition of a permit before drilling commences, may prohibit drilling
activities on certain lands lying within wilderness areas or where pollution
arises, and may impose substantial liabilities for pollution resulting from
drilling operations. Environmental regulations may cover many other areas of
Venus's operations. Violation of environmental legislation and regulations may
result in the imposition of fines and, in certain circumstances, the entry of an
order for the abatement of the conditions or suspension of the activities giving
rise to the violation. In certain cases, strict liability may be imposed by some
of those laws, rules and regulations; i.e., liability without regard to
negligence or fault. To date the Company has not been required to spend or to
invest material sums for environmental compliance.

Venus's operations could result in liability for personal injuries, property
damage, oil spills, discharge of hazardous substances, remediation and clean-up
costs and other environmental damages. Venus could also be liable for
environmental damages and assessments caused by previous owners. Any of these
could be substantial liabilities that could have a material adverse effect on
Venus's financial condition and results of operations. Venus maintains insurance
coverage for its operations, including limited coverage for sudden environmental
damages, but it does not believe that insurance coverage for environmental
damages that occur over time is available at a reasonable cost. Also, there are
significant gaps in the environmental insurance coverage that the Company does
have, and the Company could incur substantial uninsured costs related to the
applicable environmental laws and regulations.

Venus's activities are subject to the regulations promulgated by the
Environmental Protection Agency ("EPA") under, among others, the Oil Pollution
Act of 1990 ("OPA"), the Clean Water Act ("CWA"), the Comprehensive
Environmental Response, Compensation and Liability Act and its amendments
("CERCLA" and "Superfund"), and the Clean Air Act and its amendments ("CAA").
Those activities are also potentially subject to state and local regulation.

Legislation is often proposed in the U.S. Congress to reclassify certain oil and
gas production wastes as "hazardous wastes," which reclassification would make
exploration and production wastes subject to much more stringent handling,
disposal and clean-up requirements. State initiatives to further regulate the
disposal of oil and gas wastes and naturally occurring radioactive materials are
also pending in certain states, including Texas, and these various initiatives
could have a similar impact on the Company.

CERCLA and the Superfund regulations impose liability, without regard to fault
or the legality of the original conduct, on certain classes of persons that are
considered to have contributed to the release of a "hazardous substance" into
the environment. These persons include the owner or operator of the disposal
site or the site where the release occurred and companies that disposed or
arranged for the disposal of the hazardous substances found at the site. Persons
who are or were responsible for releases of hazardous substances found at the
site and persons who are or were responsible for releases of hazardous
substances under CERCLA may be subject to joint and several liability for the
costs of cleaning up the hazardous substances that have been released into the
environment and for damages to natural resources. 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. The Company is able to control directly 

                                      -6-
<PAGE>   10
the operation of only those wells with respect to which it acts as operator.
Notwithstanding the Company's lack of control over wells operated by others for
the benefit of the Company or others, the failure of the third-party operator to
comply with applicable environmental regulations may, in certain circumstances,
be attributed to the Company. The Company has no material commitments for
capital expenditures to comply with existing environmental requirements.

OTHER GOVERNMENT REGULATIONS - The oil and gas industry is subject to extensive
federal and state regulation governing the conduct of operations once production
is established. Matters that are subject to federal or state control include
permits to drill, the location of wells and limitations on production for
conservation purposes. Moreover, the Company's operations may be affected from
time to time in varying degrees by changes in federal and state laws and
regulations. The regulations specifically mentioned and these generally
described can increase Venus's cost of doing business and may affect the
Company's profitability. Because such rules and regulations are frequently
enacted, amended, expanded and reinterpreted, Venus is unable to predict the
future cost or effect of complying with such laws and regulations.

BUSINESS RISKS AND INSURANCE - The oil and gas business carries a number of
operating risks, and the exploration component of Venus's business has a
disproportionate share of such risks. Some of those risks are fire, explosions,
well blow-outs, pipe and pipeline failures, casing collapses, toxic gases,
over-pressured formations and potential environmental damages that may arise
from oil spills, gas leaks, pipe ruptures and discharges of toxic gases. Any of
these events could result in substantial losses to Venus. It maintains insurance
against some of these matters but not all of them. Furthermore, there is no
assurance that the insurance carried against the covered items will be
sufficient to cover all costs associated the covered event. The occurrence of a
loss due to lack of or insufficient coverage could have a materially adverse
effect on Venus and its financial condition. Furthermore, there is no assurance
that the insurance currently maintained will continue to be available at all or
at a price that Venus feels is reasonable.

DEPENDENCE ON KEY PERSONNEL - Venus is substantially dependent upon the services
of its Chairman and Chief Executive Officer and of its President. Venus is also
dependent upon the technical team for a large part of its business. The loss of
the services of that team or either one of the key management employees could
have a material adverse effect on Venus and its success.

SALES AND MAJOR CUSTOMERS

Venus's production is generally sold at the wellhead to various oil and natural
gas purchasing companies, typically those that are in the areas where the oil or
natural gas is produced. Crude oil and condensate are typically sold at prices
that are based on posted field prices. Natural gas is generally sold month to
month on the spot market. For example, in the month of December 1997, about 100%
of natural gas production from wells operated by Venus was sold at the wellhead
at spot market prices. The term "spot market" refers to contracts with a term of
six months or less or contracts that call for a redetermination of sales prices
every six months or more often. The Company believes that the loss of one or
more of its current natural gas spot purchasers should not have a material
adverse effect on the Company's business because any individual spot purchaser
could be readily replaced by another spot purchaser who would pay a similar
sales price. However, although the Company believes that there will be a spot
market available, that market is highly sensitive to changes in current market
prices, and a downward trend in spot market prices can have a significant impact
on the Company's cash flow.

Three customers each accounted for approximately 10% or more of consolidated
revenues in 1997. Those are Dow Hydrocarbons & Resources, Inc. (22%), Stephens &
Johnson Operating Company (10%) and Flying J Oil & Gas,Inc. (10%). In 1996 three
customers accounted for approximately 10% or more of consolidated  revenues.
Those are Stephens & Johnson Operating Company (31%), Scurlock Permian
Corporation (17%), and Lantern Petroleum Corporation (10%).

OIL AND NATURAL GAS RESERVES

At December 31, 1997, third-party independent petroleum engineers evaluated
properties representing approximately 88% of PV-10 Value, and Venus's in-house
engineers evaluated the remaining reserves. The PV-10 Values shown in this
Annual Report on Form 10-K are not intended to represent the current market
value of the estimated net Proved Reserves of oil and natural gas owned by
Venus. Neither prices nor costs have been escalated in the reserve estimates,
but prices do include the effects of hedging contracts in place at that date.

The Company has not filed any estimate of oil or gas reserve information with
any federal authority or agency other than the SEC. The following table
summarizes the estimates of the Company's net Proved Reserves as of December 31,
1997.

The foregoing table represents an increase in value and an increase in amount of
reserves as compared with December 31, 1996. See Note 12 of Notes to
Consolidated Financial Statements (Supplementary Oil and Gas Disclosures) for

                                      -8-
<PAGE>   12

The reserve data set forth herein present estimates only. In general, estimates
of economically recoverable oil and gas reserves and of the future net revenues
therefrom are based upon a number of variable factors and assumptions, such as
historical production from the subject properties, the assumed effects of
regulation by governmental agencies and assumptions concerning future oil and
gas prices and future operating costs, all of which may vary considerably from
actual results. All reserves are evaluated based on the assumption that all
reported data are stated at standard temperature and pressure. If that
assumption proves to be incorrect, there can be a substantial effect on
estimated gas reserves. All such estimates are to some degree speculative, and
classifications of reserves are only attempts to define the degree of
speculation involved. For these reasons, estimates of the economically
recoverable oil and gas reserves attributable to any particular group of
properties, classifications of such reserves based on risk of recovery, and
estimates of the future net revenues expected therefrom prepared by different
engineers or by the same engineers at different times may vary substantially.
The Company, therefore, emphasizes that the actual production, revenues,
severance and excise taxes, development and operating expenditures with respect
to its reserves will likely vary from such estimates, and such variances could
be material.

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 in the initially estimated 
reserves, and those variations may be substantial.

In accordance with applicable requirements of the SEC, the estimated discounted
future net revenues from estimated Proved Reserves are based on prices and costs
as of the date of the estimate unless such prices or costs are contractually
determined at such date. Actual future prices and costs may be materially higher
or lower. Actual future net revenues also will be affected by factors such as
actual production, supply and demand for oil and natural gas, curtailments or
increases in consumption by natural gas purchasers, changes in governmental
regulations or taxation and the impact of inflation on costs.

        On December 31, 1997, three wells were being drilled. As of March 18,
1998, two of those wells were producing, and the third well was shut-in and
waiting on a gas pipeline connection to be constructed before production could
continue.

PRODUCTS AND MARKETS

Oil and natural gas are the principal products currently produced by Venus.
Venus does not refine or process the oil or natural gas that it produces. Venus
sells the oil it produces under short-term contracts at market prices for the
areas in which the producing properties are located, generally at FOB field
prices posted by the principal purchaser of oil in the area. Venus sells the
natural gas produced from its properties under short-term contracts to entities
that have pipelines in the vicinity of the production or that will build short
gathering lines to such properties. In some instances, Venus will own the
gathering line. Typically, the contracts for natural gas sales are for terms
less than six months. Venus Development, Inc., a wholly-owned subsidiary of the
Company, uses financial hedging instruments to manage its exposure to
fluctuations in commodity prices.

DEFINITIONS OF CERTAIN OIL AND GAS TERMS

The terms defined in this section are used throughout this Annual Report on Form
10-K.

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

Bcf. One billion cubic feet of natural gas and related compounds at standard
conditions.

Bcfe. Equivalent of one billion cubic feet of natural gas. In reference to
natural gas, natural gas equivalents are determined using the ratio of six Mcf
of natural gas to one Bbl of crude oil, condensate or natural gas liquids.

Btu. One British thermal unit. The quantity of heat required to raise the
temperature of one pound of water one degree Fahrenheit at standard conditions.

Completion. The installation of permanent equipment for the production of oil or
gas, or, in the case of a dry hole, the reporting of abandonment to the
appropriate authority.

Developed Acreage. The number of acres that are allocated or assignable to
producing wells or wells capable of production.

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

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

Exploitation. The process whereby the value of a property is attempted to be
increased by working over existing wells, by making new completions in existing
wells and by conducting other similar operations intended to increase production
from existing wells in a developed area.

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


                                      -13-
<PAGE>   17
expected limits of the known reservoir. These wells involve a high degree of
risk, given the unknown nature of the horizons being tested.

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

LIBOR. A rate per annum at which deposits in U.S. Dollars in immediately
available and freely transferable funds would be offered in the London Interbank
Eurodollar market.

Mbbl.  One thousand barrels of crude oil or other liquid hydrocarbons.

Mmbtu.  One million Btu's.

Mcf. One thousand cubic feet of natural gas and related compounds at standard
conditions.

Mcfe. The equivalent of one thousand cubic feet of natural gas. In reference to
natural gas, natural gas equivalents are determined using the ratio of six Mcf
of natural gas to one Bbl of crude oil, condensate or natural gas liquids.

Mmcfe. The equivalent of one million cubic feet of natural gas. In reference to
natural gas, natural gas equivalents are determined using the ratio of six Mcf
of natural gas to one Bbl of crude oil, condensate or natural gas liquids.

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

Production Cost. Also referred to as lifting cost, the cost of operation and
maintenance of wells, related equipment and facilities that are expensed as
incurred as a part of the cost of oil and gas produced; e.g., labor to operate
the wells and facilities, repair and maintenance expenses, materials and
supplies consumed, taxes and insurance on property, and severance taxes.

PV-10 Value, or Present Value of Estimated Future Net Revenues. The present
value of estimated future net revenues as of a specified date, after deducting
estimated production and ad valorem taxes, future capital costs and operating
expenses, but before deducting federal income taxes. The estimated future net
revenues are discounted at an annual rate of 10% to determine their "present
value." The present value is shown to indicate the effect of time on the value
of the revenue stream and should not be construed as being the fair market value
of the properties. Estimates have been made using constant oil and natural gas
prices and operating costs at the specified date.

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

Prospect. An area that has been interpreted to be prospective for commercial
hydrocarbon accumulation based on seismic evaluations; leases may or may not
have been acquired in the area of the Prospect.

Prospect Lead. An area that preliminary evaluations suggest may be prospective
for commercial hydrocarbon accumulation; usually no seismic studies will have
been conducted on such an area, nor will have any leases been acquired in it.


                                      -14-
<PAGE>   18
Proved Developed Producing Reserves, or PDP. Proved Reserves to be produced by
existing wells from completion intervals open to production.

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

Proved Developed Non-Producing Reserves, or PDNP. Proved Reserves to be produced
from existing wells but that are now behind the casing or at minor depths below
the bottom of the hole. The cost of opening up such reserves are expected to be
relatively minor.

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

Proved Undeveloped Reserves, or PUD. Proved Reserves that are under undeveloped
spacing units that are so close and so related to developed spacing units that
they may be assumed with confidence to become commercially productive when
drilled.

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

Seismic Data. Geophysical information collected by transmitting sound waves into
the earth from a transmitter, or source, and measuring, with appropriate
receivers, the time of the sound waves' arrival and their intensity when they
are reflected or refracted back to the surface.

2-D seismic data is collected along a surface line of sources and receivers,
giving a section representing a slice through the earth.

3-D seismic data is collected by distributing sources and receivers over an
area, yielding a volume of information representing the 3-dimensional section of
earth beneath the area being studied. The improved imaging of 3-D data makes it
the preferred advanced technological method of attempting to determine the
location, extent and properties of hydrocarbon accumulations.

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

Working Interest, or WI. The cost-bearing operating interest that gives the
owner the right to drill, to produce and to conduct operating activities on the
property and to share a proportionate part of production.

ITEM 2.  PROPERTIES

TITLE TO PROPERTIES

Substantially all of Venus's properties are Working Interests derived from oil
and gas leases on property owned by third parties. Very little of its property
is mineral or fee ownership. Venus usually performs title research before
acquiring leases or interests in leases, and it believes that it has
satisfactory title to its producing properties. The degree of research varies
depending on the value initially assessed to the property, whether the property
is producing at the time of acquisition, and other factors. The properties are
usually subject to the rights of lessors to be paid a Royalty Interest out of
production. They are also often subject to overriding royalties and other
burdens, none of which the Company believes to be a material burden on the value
of the Company's interest. Substantially all of the Company's properties are and
will continue to be subject to liens and mortgages to secure borrowings under
its credit facilities.

Substantially all of the properties owned by Venus are subject to exploration or
development agreements with third parties. The exploration and development
agreements are subject to "Area of Mutual Interest," or "AMI," provisions that
give the third party participants certain limited rights of first refusal on
interests acquired within the AMI. If the third party elects not to acquire such
interest, Venus usually will have the right to acquire the third party's
proportionate part of the interest. Once interests are acquired, the parties to
the agreements usually also have an election before a well is drilled. If a
party elects not to drill, Venus usually has the right to acquire certain
interests from the non-drilling party, but depending upon the size of the
interest and the cost of the proposed well, Venus may or may not elect to
acquire that interest. In several of the exploration and development projects in
which Venus is involved, the election not to participate or not to drill by a
third party owner of a large part of the project could materially affect the
value of Venus's interest in that project.

In May of 1997, the Company's executive and operating offices were relocated to
San Antonio, Texas, where it occupies premises of approximately 12,570 useable
square feet pursuant to a lease that expires on December 31, 2002. It also
maintains an office in Houston, Texas. The Houston office was formerly the
Company's principal executive office, and its address is 16800 Greenspoint Park
Drive, Suite 300 South, Houston, Texas 77060. That lease terminates on July 31,
1998. The Company's annual rental expense is approximately $257,000. The lease
of the San Antonio office space provides for increased rents at stated amounts
and intervals and an adjustment for variations in utility costs.

See "Item 1 - BUSINESS" for additional information concerning the Company's oil
and gas properties.

ITEM 3.  LEGAL PROCEEDINGS

The Company is a party in a number of lawsuits arising in the ordinary course of
business. In the opinion of management, final judgments or settlements, if any,
that may be awarded or entered into in connection with any one or more of these
suits would not have a material adverse effect on the Company's financial
position or results of operations.

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

This Annual Report on Form 10-K (particularly this Item 7) contains statements
that are considered "forward-looking statements," as defined in the Private
Securities Litigation Reform Act of 1995. As discussed in Item 1 - "BUSINESS"
under "-Forward-Looking Statements" and "-Risk Factors," actual results may
differ materially from those contemplated by those forward-looking statements.


                                      -19-

GENERAL

In 1997, the Company went through a major transformation as a result of the
Acquisition discussed in Item 1 "BUSINESS" above. Legally, Xplor Corporation
acquired the assets of New Venus. However, accounting principles require that
this transaction be treated as a reverse acquisition of the Company by New
Venus. After the transaction, the Company's name was changed from Xplor
Corporation to Venus Exploration, Inc. Under the reverse acquisition accounting
principles, the results of operations and financial information for prior years
shown in this report are those of the predecessor Venus entities, not Xplor
Corporation. Moreover, operational data shown herein for periods prior to May
21, 1997; e.g., production information, reflect the operations of New Venus and
its predecessors. Accordingly, comparison of information in this report with
prior Xplor Corporation corporate reports previously filed under the Security
Exchange Act of 1934 is not an appropriate performance measure.

The oil and gas reserves added by the Acquisition, plus the completion of new
wells drilled in the Company's 1997 drilling program, increased Venus' Proved
oil and gas Reserves, net of 1997 production and revisions of previous
estimates, by over 300% from 2.8 Bcfe on December 31, 1996, to 12.4 Bcfe on
December 31, 1997.

In 1997, the production obtained and the revisions of previous estimates of
reserves that were incurred together resulted in a reduction of reserves of
approximately 1 Bcfe, so the gross increase in Proved Reserves was 10.6 Bcfe. Of
that gross increase in Proved Reserves, 69%, or 7.3 Bcfe, is attributable to the
Acquisition transaction, and 31%, or 3.3 Bcfe, to the Company's 1997 exploration
and development program. Of the 3.3 Bcfe Proved Reserves increase from the
drilling and exploration programs in 1997, 29.8%, or 1 Bcfe, was comprised of
Proved Undeveloped Reserves in the Constitution Field, Jefferson County, Texas,
and 24.4%, or 0.8 Bcfe, was comprised of Proved Developed and Proved Undeveloped
Reserves in the Allen Field, Seminole County, Oklahoma. The balance of the
Company's Proved Reserve growth was through extensions, discoveries and
additions in other fields, including the Shanghai Field, Wharton County, Texas,
and the Vidor - South Field, Orange County, Texas.

The Company's 1997 drilling program resulted in the drilling of 15 wells during
1997 and the first quarter of 1998. Five of the 15 wells drilled were
Exploratory Wells, and 10 were Development Wells. Twelve of the 15 wells have
been completed as oil and gas wells, one well was completed as a non-commercial
oil well, and as of March 20, 1998, two wells were in the process of being
completed. Six of the 15 wells drilled by the 1997 drilling program were
producing revenue in December 1997; as of the end of March 1998, 10 are expected
to be producing revenue.

Management's business plan for its 1998 program provides for capital
expenditures of approximately $7 million for exploration and development
drilling and land and 3-D seismic acquisition. Approximately $1 million of this
amount ($7 million) is expected to be financed under the Stratum Facility
described below, leaving approximately $6 million to be financed by other
sources of corporate finance as discussed below. The number of wells proposed to
be drilled under management's 1998 program is 9 Exploratory and 11 Development
Wells. The cost of 3-D Seismic acquisition included in the 1998 plan is
estimated at $750,000. The Company may elect to reduce its interests, through
sales, farmouts or other transactions, in certain wells or seismic projects or
to include those wells or projects in a joint venture with industry
participants, in which event the Company's capital investment and upside
potential would be lower. The actual timing of the drilling of the wells is
dependent upon may unpredictable factors, and in all likelihood the 1998
drilling program will not be completed until 1999.

The number of wells that were drilled in 1997 and that are currently being
operated required a large increase in Venus's operations, accounting and
administrative staff. However, Venus believes that the current staff levels can
manage the new wells in the 1998 drilling program at a lower marginal cost than
experienced in 1997.

<PAGE>   24

The Company's general and administrative expense increased significantly from
1995 to 1997. This increase is due primarily to two factors; i.e., significantly
expanded exploration activities and various corporate restructurings during 1996
and 1997. The corporate restructurings included (i) the incorporation of a
United Kingdom public limited company, (ii) the repatriation of the United
Kingdom company, and (iii) the Acquisition. All contributed to the significant
increase in both 1996 and 1997 of the Company's general and administrative
costs.

Venus uses the successful efforts method of accounting of its oil and gas
activities. It capitalizes the costs to acquire mineral interests in oil and gas
properties, to drill and to equip Exploratory Wells that result in Proved
Reserves, and to drill and to equip Development Wells. It expenses the costs to
drill Exploratory Wells that do not result in Proved Reserves, costs of
geological, geophysical and seismic data and analysis, and the costs of carrying
and retaining unproved properties. Capitalized costs of producing oil and gas
properties, after considering estimated abandonment costs and estimated salvage
values, are depreciated and depleted using the unit-of-production method.
Unproved oil and gas properties that are individually significant are
periodically reviewed for impairment of value, and a loss is recognized at the
time of impairment by providing an impairment allowance.

The Acquisition and the corporate restructuring in 1996 affected the reported
financial results in various ways. The historical financial statements of the
Company are that of a predecessor entity for all of 1995 and the first six
months of 1996. On July 1, 1996, that predecessor entity transferred most but
not all of its interest in the oil and gas properties to another predecessor
entity of the Company. Comparisons of revenues and expenses between 1997 and
1996 are affected by the inclusion in the first half of 1996 of the revenues and
expenses attributable to oil and gas properties and other assets and liabilities
that were, for accounting purposes, deemed distributed on July 1, 1996.
Likewise, comparisons of 1996 results with 1995 results are affected because
1995 contains 12 months of activity attributable to the assets and liabilities
deemed distributed as of July 1, 1996, while 1996 contains six months of
activity.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1997, COMPARED WITH YEAR ENDED DECEMBER 31, 1996 -

The Company experienced a net loss of $4.2 million for 1997 versus a net loss of
$2.0 million for 1996. The Company reported impairment losses in 1997 and 1996
of $1.1 million and $1 million, respectively. General and administrative cost
increased by $1,549,223, or over 100%.

Oil and gas production was 896 Mmcfe in 1997 compared to 207 Mmcfe in 1996, an
increase of over 300%. Of the 689 Mmcfe increase, approximately 285 Mmcfe was
due to successful drilling activities. The remainder, 404 Mmcfe, was due to
production from the properties acquired from Xplor and Lomak. Average oil prices
declined from $18.80 per barrel in 1996 to $17.72 in 1997, a 6% decrease.
Average natural gas prices declined from $2.55 per Mcf to $2.44, a 4% decrease.
Despite the decrease in average product prices, oil and gas revenue of $2.5
million for 1997 increased by $2.0 million over 1996 revenue of $0.5 million,
primarily due to successful drilling and the Acquisition.

Oil and gas production costs in 1997 were $963,822 ($1.08 per Mcfe) compared
with $286,030 in 1996 ($1.38 per Mcfe). This decrease is due mainly to the lower
operating cost of new properties acquired through successful drilling and the
Acquisition. The 1997 production or lifting cost as a percentage of oil and gas
sales decreased to 39%, compared with 53% in 1996. 


                                      -21-
<PAGE>   25
During 1997 the Company booked impairment expense of $1.1 million as compared to
the $1.0 million recorded in 1996. The impairment expenses for both 1997 and
1996 relate primarily to the cost, initially capitalized, of acquiring and
drilling Exploratory and Development Wells that were completed but that failed
to establish enough reserve value to justify their carrying value. In such cases
an impairment is recognized to reduce the capitalized cost to the estimated fair
market value of each well, which valuation is on a field by field basis. Costs
of Exploratory Wells that are not completed, but are plugged and abandoned, are
charged directly to dry hole expense.

The exploration expense, including geological, geophysical and seismic data
acquisition and analysis and dry hole expenses, was $504,983 in 1997, compared
to $116,905 in 1996. The increase is due mainly to the Company's drilling of one
Exploratory Well dry hole during the year and increased activity in exploration
joint ventures operated by the Company that resulted in an increase in
geological and geophysical costs.

During 1997, general and administrative expense of $2,923,764 increased
$1,549,223 from $1,374,541 in 1996. This increase was primarily due to the
significant increase in exploration activity and the Acquisition. The 1997
exploration activities led to the creation of 12 new employee positions and the
increased use of third-party engineering services and other professional
consultants. The 1997 amount also includes $252,002 of non-cash compensation
expense related to stock options granted to directors and costs in connection
with the corporate restructuring.

The Company's 1997 interest income of $77,658 increased by $22,230 over 1996 due
primarily to interest received from the investment of cash acquired in the
Acquisition.

Interest expense was $203,213 in 1997, compared to $10,331 in 1996. The $192,882
increase is primarily due to increased borrowings by Venus Development, Inc.
Approximately $81,535 of the interest expense reported by Venus Development,
Inc., represents amortization of deferred financing cost, not a current or
future cash expense. The average balances of interest-bearing debt was
$1,030,000 in 1997, compared to $70,000 in 1996.

YEAR ENDED DECEMBER 31, 1996, COMPARED WITH YEAR ENDED DECEMBER 31, 1995 -

The Company reported a net loss of $2.0 million for 1996 versus a net loss of
$0.7 million for 1995. The Company reported impairment expense of $1 million in
1996 and none in 1995. General and administrative expense increased by $0.63
million.

Oil and gas production was 207 Mmcfe in 1996 compared to 380 Mmcfe in 1995, a
decrease of over 45%. Accordingly, revenues decreased from $0.8 million for 1995
to $0.5 million in 1996, a decrease of $0.3 million, or 38%. Production in 1995
and related revenues include revenue from properties that were sold in early
1996 as well as from properties that were deemed distributed to shareholders
effective July 1, 1996. As a result, these properties reported twelve months
production and related revenue in 1995 but only six months in 1996. The decline
in revenue was lower than the decline in production because of the increase in
average prices. Average oil prices increased from $16.17 per barrel in 1995 to
$18.80 in 1996, a 16% increase. Average natural gas prices increased from $1.43
per Mcf in 1995 to $2.55 in 1996, a 78% increase. The 1996 depletion rate of 14%
as a percentage of sales is comparable to 1995's rate of 16%.

Oil and gas production costs in 1996 were $286,030 ($1.38 per Mcfe) compared
with $479,950 in 1995 ($1.26 per Mcfe). The decrease in total cost was due to
the properties retained by the predecessor entity and properties sold in early
1996. The costs for 1995 include 12 months of operations for these wells, while
1996 reflects operations for six months for the wells retained by the
predecessor entity and one to three months operations for the properties sold
during the first half of 1996. Production cost per Mcfe increased due mainly to
costs incurred on the Company's Oklahoma wells to


                                      -22-
<PAGE>   26
improve production and operating efficiencies. The 1996 lifting cost of oil and
gas sales of 53% relative to sales decreased by 13% from the prior year's cost
of 61% relative to sales. Increased average product prices contributed to the
decrease in cost as a percent of sales.

Exploration (including geological, geophysical and seismic data and analysis and
dry hole costs) expense was $116,905 in 1996 compared to $532,222 in 1995, a
$415,317 decrease from 1995. The amount for 1995 includes dry hole costs of
$264,000. There was no dry hole expense in 1996. The most significant component
of the balance of the remaining $151,000 decrease is the result of the Company
selling part of its participation in an exploration joint venture to a new
participant. This reduced the Company's share of the allocated geological,
geophysical, seismic and other venture expenses.

During 1996, general and administrative expense of $1,374,541 increased $628,698
from $745,843 in 1995. This increase was primarily due to an increase in
overhead to support increased exploration activity and overhead costs related to
corporate restructuring that resulted in an increased use of consultants, such
as attorneys, accountants and engineers. The general and administrative expense
for 1996 also includes $283,430 of compensation expense related to stock options
granted new non-employee directors.

The Company's 1996 interest income of $55,428 decreased by $17,510 over 1995
because for twelve months in 1995, but only six months in 1996, the Company had
notes receivable from certain shareholders. These notes, which totaled $480,685
at December 31, 1995, were retained by the predecessor entity and for accounting
purposes treated as distributed to shareholders on July 1, 1996. As a result,
interest income for 1996 reflects six months of interest from these notes while
1995 reflects twelve months.

Interest and other expenses were $10,331 in 1996, compared to $27,041 in 1995.
The $16,710 decrease was primarily due to a $17,051 worthless inventory write
down. Interest expense in 1996 was $341 higher than in 1995. The average
balances of interest-bearing debt were $70,000 in 1996, compared to $131,000 in
1995. The interest-bearing debt outstanding in 1996 consisted of bank debt that
was subject to a much higher interest rate than the interest-bearing debt
outstanding during 1995, which consisted of notes payable to former
shareholders.

ACCOUNTING POLICIES

In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS No.
130, "Reporting Comprehensive Income," which establishes standards for reporting
and displaying of comprehensive income and its components. This statement
requires a separate statement to report the components of comprehensive income
for each period reported. The provisions of this statement are effective for
fiscal years beginning after December 15, 1997. Management believes that the
Company currently does not have items that would require presentation in a
separate statement of comprehensive income.

In June 1997, the FASB also issued SFAS No. 131, "Disclosure about Segments of
an Enterprise and Related Information" ("SFAS 131"), which establishes standards
and requires that those enterprises report selected information about operating
segments in interim financial reports issued to shareholders. It also
establishes standards for related disclosure about products and services and
major customers. This statement is effective for financial statements for
periods beginning after December 15, 1997. The Company is currently evaluating
the impact that SFAS 131 will have on its financial statement disclosures.

LIQUIDITY AND CAPITAL RESOURCES

LIQUIDITY

At December 31, 1997, the Company had a working capital deficit of $768,939
compared with working capital of $700,275 at December 31, 1996, a decrease of
$1,469,214. The ratio of current assets to current liabilities at December 31,
1997, was .80 to 1 compared with 1.5 to 1 at December 31, 1996.

Net cash used in operating activities during 1997 was $1,276,042, whereas
$406,433 was used during 1996. Cash and equivalents decreased by $621,481
principally due to capital expenditures related to exploration and development
and the cost of administrative services required to support the increased
exploration activities and corporate restructurings. The increase of $1,478,229
in accounts receivable was primarily the result of the timing of revenue
receipts and joint interest receivables. The increase in current liabilities of
$2,406,027 is attributable to the increased level of drilling conducted by the
Company in 1997 and higher revenue payables to nonoperating interest owners as a
result of the increasing number of operated properties. 

CAPITAL RESOURCES

To fund its business activities, Venus had previously relied on bank financing,
cash flow from operations, sales of properties and joint ventures with industry
participants. In 1996, the decision was made to sell equity interests and to use
limited recourse financing under a credit facility with Stratum Group Energy
Partners, LP. In 1997, a more conventional line of credit facility was set up
with Wells Fargo Bank (Texas), N.A. In the future, Venus intends to finance its
drilling plans and other operations with cash flow from operations, borrowings
from the two credit facilities, sales of non-strategic properties, and public
and private equity sales.

The prices paid to Venus and other producers in the first three months of 1998
have been considerably below the average price received in 1997. That diminished
revenue could have a material effect on the number of wells drilled by the
Company in 1998. Cash flow from existing properties will not fund management's
1998 drilling plan; therefore, the number of wells drilled by the Company will
depend on a number of external factors, the most important of which is the
availability to the Company of debt and equity capital in public and private
capital markets. In addition, if Venus is unable to generate sufficient cash
flow from operations to service its debt, it may be required to refinance all or
some of its debt, to sell certain assets or to obtain additional debt or equity
financing. There is no assurance that any such additional funding will be
available. Any major property acquisitions are also dependent upon receiving
adequate financing to fund the purchase; therefore, any such transaction will be
subject to the same factors.

While Venus regularly evaluates and discusses possible acquisitions, it has no
present agreements or commitments with regard to any specific such acquisition.
Any acquisition outside of current exploration and development programs would
require additional financing and would be dependent upon financing options
available at that time.

Venus has been successful in the highly capital-intensive oil and gas
exploration business. The capital resources and liquidity needed to run the
business over the last several years have been provided in large part from two
main sources: Cash sales of properties that were the result of Venus's past
exploratory successes and debt and equity financing. There is no assurance that
such sources of capital will be available in the future.

The successes of 1996 and 1997 provide a cash flow stream that is dependent upon
the various factors that generally affect the domestic oil and gas markets;
e.g., price, government regulation and normal oil and gas operational events. Of
course, the current trend of lower oil and gas prices has a negative effect on
cash flow from current production, the lines of credit that are supported by
reserve value, and the availability of the new capital resources needed to
explore and develop the extensive portfolio of projects and prospects that Venus
has under study. Increases in the lines of credit are directly dependent upon
continued successes in drilling productive wells and the prices paid for oil and
natural gas

production at any given time. Indirectly, those continued successes would help
in any efforts to raise additional capital resources.

STRATUM FACILITY

Effective October 8, 1996, Venus entered into a credit facility (the "Stratum
Facility") with Stratum Energy Group Partners, L.P. ("Stratum"). The Stratum
Facility provides a term loan with a maximum limit of $20 million. The line of
credit limit varies with the value of the borrowing base, which is based on the
value of the properties subject to the underlying deed of trust. The lender's
only recourse is against Venus Development, Inc. ("Venus Development"), a
wholly-owned subsidiary of Venus Exploration, Inc., and the properties securing
the Stratum Facility. The final drawdown can be made no later than October 8,
1998, and its maximum term is 7 years. The right of Venus Development to draw on
the line of credit is subject to numerous collateral tests. The interest rate
charged on outstanding advances is floating prime plus 1%. Prepayment is not
allowed until the earlier of (i) when the full line has been drawn down, or (ii)
October 8, 1999.

As a part of the Stratum Facility, Stratum was granted an overriding royalty
interest equal to 5% of Venus Development's net revenue interest in the
properties subject to the Stratum deed of trust. Stratum can convert its
overriding royalty interest into Venus Common Stock at $3/share, with the
present value of the overriding royalty interest being determined based on a 15%
discount rate. Stratum also has certain restricted warrants that become
exercisable after Venus conducts its next public offering, and the price per
share pursuant to those warrants is 125% of the public offering price. The
conversion rights and the warrants are exercisable only against a pool of Venus
Exploration Common Stock (the "Conversion Share Pool") that are owned by the
shareholders of the former Venus entity that was a party to the Acquisition.
(The Conversion Share Pool contains 589,882 shares of Venus Exploration common
stock, and those shares are held in an escrow account maintained by the Frost
National Bank.) In the event that Stratum exercises its conversion rights or
warrants, no new shares of the Company's Common Stock would be issued to satisfy
those rights or warrants.

HEDGING ACTIVITIES

On certain properties, Venus uses commodity derivative contracts to protect and
to ensure cash flow levels. Those properties currently are limited to those that
are owned by Venus Development and that are subject to the financing facility
provided by Stratum. The Stratum Facility requires that those hedges be used, in
part, because it is arranged in such a way that the lender has no recourse
against the assets of the parent that are not owned by Venus Development. On
December 2, 1996, Venus Development entered into a financial swap, whereby the
counterparty agrees to pay Venus Development the difference between the floating
price and the fixed price for certain volumes of production in future months
(commencing with January 1997 production) if the floating price falls below the
negotiated fixed price of $2.0497 per mmbtu for natural gas or $19.045 per
barrel for oil, respectively. Should the floating price exceed the fixed price
for natural gas or oil, the Company is required to remit the difference to the
counterparty. As of December 31, 1997, quantities hedged are 81,996 Mmbtu's of
natural gas and 28,656 barrels of oil. This financial swap agreement expires
December 31, 2001. As of December 31, 1997, the estimated fair value of the
Company's swap positions was a net receivable of approximately $34,000 based
upon an estimate of what the Company would receive if the contracts were
liquidated. The net effect of Venus's commodity derivative contracts reduced oil
and gas revenues by $41,604 and $1,719 in the years ended December 31, 1997 and
1996. There were no hedges in place in 1995.

WELLS FARGO FACILITY

Effective December 19, 1997, the Company entered into a revolving line of credit
facility (the "Wells Fargo Facility") with Wells Fargo Bank (Texas), N.A.
("Wells Fargo"). The Wells Fargo Facility is a $50 million revolving line of
credit subject to a borrowing base supported by the value of the mortgaged oil
and gas reserves on which Wells Fargo has a first lien. Those reserves include
substantially all of the assets of the Company other than those that are owned
by Venus Development. Draws may be made as either prime rate advances or LIBOR
advances. The borrowing base as of March 18, 1998, was $5,250,000, of which
$2,053,270 had been drawn at that date. The Facility terminates on June 30,
2000.


                                      -25-
<PAGE>   29

Prime rate advances accrue interest at the floating "Prime Rate" quoted by Wells
Fargo. LIBOR advances accrue interest at LIBOR plus 1.75%. The LIBOR rate also
is increased to cover any bank reserve costs, and if there is any increase in
the administration costs of the LIBOR advances due to changes in the law, Wells
Fargo can assess additional charges to cover those additional costs. The
advances received by Venus as of December 31, 1997, and as of March 18, 1998,
were prime rate advances, and the interest rate was 8,5% per annum on both such
dates. Fees payable by Venus under the agreement include a borrowing base
determination fee ($2,500 for each regular redetermination), a facility fee
(3/8% of any increase in the borrowing base), and a commitment fee (a quarterly
payment based on a charge of 3/8% per annum on the average unused borrowing base
for each day during the preceding calendar quarter).

Negative restrictions imposed upon Venus by the Wells Fargo agreement include
Venus's agreement to: not declare a dividend; not enter into any hedging
agreement covering more than 90% of Venus's projected monthly production or for
periods beyond the current calendar year; not amend the Stratum agreements; not
advance Venus Development more than $20,000 per year; not allow gas balancing,
take-or-pay contracts or other similar situations to exist to the extent that
Venus would not be entitled to receive the full value of delivered production;
not merge or consolidate with anyone else unless Venus is the survivor; not
change its control or management; and not allow other liens to be placed on
Venus's properties.

In order to use the Wells Fargo Facility, Venus must maintain Wells Fargo's
first lien on the properties subject to the deed of trust and other usual
covenants. Venus must maintain a 1:1 ratio of (a) the sum of all of its current
assets and the unused amount of the borrowing base, to (b) all of its accounts
payable and other current liabilities. At December 31, 1997, the Company was not
in compliance with the tangible net worth requirement. The Company obtained a
waiver from the lender as of December 31, 1997 which included a reduction in
tangible net worth requirement to $7,500,000. However, because of uncertainty
regarding the Company's ability to remain in compliance with this covenant
through the first quarter of 1998, the outstanding balance has been classified
as a current liability in the December 31, 1997 financial statements.

INFLATION

Although many of Venus's expenses and items of income may be affected by
inflation, inflationary costs have not had a significant effect on its results
of operations. However, the tightness in the drilling rig market is a concern
and may lead to inflationary effects in the near future.

IMPACT OF YEAR 2000

Concern over the year 2000 arises because many computer microprocessors have
been designed, and application software has been written, using two digits,
rather than four, to define the applicable year. Any of Venus's microprocessors
or application software that are time-sensitive may recognize a date of "00" as
the year 1900, rather than the year 2000. This could result in a system failure
or miscalculations causing disruptions of operations; e.g., a temporary
inability to operate machinery, to process transactions, to send invoices, or to
otherwise engage in normal business activities. Venus has conducted a review of
its computer systems to identify any such problems, and it has not identified
any problems that will require the expenditure of material amounts to address.
Venus has developed a plan to conduct tests throughout 1998 to evaluate the
situation.

The Company has received written representations from the accounting firms that
manage the Company's accounting and payroll about any year 2000 risks, and based
on those representations Venus believes that there is no problem with those
firms' computer systems in that regard. Venus has business relations with many
other companies, including various purchasers of production. It has not checked
with those entities, but it believes that even if those entities have any year
2000 problems, those problems will not have a material adverse impact on the
Company's business or finances. However, until that time, Venus cannot give any
assurances regarding the year 2000 effect.

ITEM 9.  CHANGES IN, AND DISAGREEMENTS WITH, ACCOUNTANTS ON ACCOUNTING AND
         FINANCIAL DISCLOSURE

Effective June 3, 1997, the Company replaced Arthur Andersen LLP ("AA") with
KPMG Peat Marwick LLP as the Company's independent accountant at the
recommendation of the Board of Directors of the Company.

AA's reports on the financial statements of the Company for the past two years
have not contained an adverse opinion or a disclaimer of uncertainty, audit
scope or accounting principles. During the two most recent fiscal years and the
interim period since the end of the Company's fiscal 1996, there have not been
any disagreements with AA on any matter of accounting principles or practices,
financial statements or disclosure, or auditing or scope of procedure, which
disagreement(s), if not resolved to the satisfaction of AA, would have caused it
to make reference to the subject matter of the disagreement(s) in connection
with its report.

                          Independent Auditors' Report

The Board of Directors and Shareholders of
Venus Exploration, Inc.:

We have audited the accompanying consolidated balance sheets of Venus
Exploration, Inc. and subsidiaries and predecessor entities, as described in
note 7 to the consolidated financial statements, as of December 31, 1997 and
1996, and the related consolidated statements of operations, shareholders'
equity (deficit), and cash flows for each of the years in the three-year period
ended December 31, 1997. 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 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 consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Venus Exploration,
Inc. and subsidiaries and predecessor entities, as described in note 7 to the
financial statements, as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the years in the three-year period
ended December 31, 1997, in conformity with generally accepted accounting
principles.

                   Notes to Consolidated Financial Statements

                        December 31, 1997, 1996, and 1995

(1) ORGANIZATION AND BUSINESS COMBINATION

     Venus Exploration, Inc. (the Company) is primarily engaged in the business
     of exploring for, acquiring, developing and operating on-shore oil and
     gas properties in the United States. The Company presently has oil and
     gas properties, acreage and production in ten states.

     On May 21, 1997, Venus Exploration, Inc. (the Company), then known as Xplor
     Corporation ("Xplor"), acquired substantially all of the assets and
     liabilities of The New Venus Exploration, Inc. ("New Venus"), a Texas
     corporation, in exchange for 5,626,473 shares of the Company's previously
     authorized and unissued shares of common stock and warrants to purchase
     272,353 additional shares of common stock. Simultaneously, the Company
     acquired certain oil and gas properties of two wholly-owned affiliates of
     Lomak Petroleum, Inc. (together, "Lomak") in exchange for 2,037,171 shares
     of the Company's previously authorized and unissued shares of common stock
     and warrants to purchase 272,353 additional shares of common stock. At the
     same time, Lomak acquired from existing stockholders of the Company 97,008
     shares of common stock. As a result of these transactions (collectively,
     the "Acquisition") the former stockholders of New Venus acquired, as of the
     effective date of the Acquisition, 58% of the Company's outstanding stock
     and thus voting control, and Lomak acquired 22%, while the preexisting
     stockholders of the Company owned 20%. On June 4, 1997 Xplor changed its
     name to Venus Exploration, Inc.

     For financial reporting purposes, the transactions described above have
     been accounted for as a reverse acquisition whereby New Venus is deemed to
     be the acquirer. Accordingly, the historical consolidated financial
     statements of the Company and predecessor entities are presented as the
     historical consolidated financial statements of the Company and the assets
     acquired and liabilities assumed from Xplor and Lomak have been recorded at
     fair value as of the date of the combination as required under purchase
     accounting. The consolidated financial statements reflect the operations
     solely of the Company for the periods prior to May 21, 1997, whereas such
     financial statements reflect the operations of the combined entities for
     the period subsequent to May 21, 1997.

                                                                     (Continued)

(1) ORGANIZATION AND BUSINESS COMBINATION, CONTINUED

     The effect of the combination transactions was primarily the recording of
     the assets and liabilities of Xplor and Lomak at their fair value. The
     combined amounts for Lomak and Xplor were as follows:

       Cash                                                       $ 2,880

       Trade accounts payable and other liabilities                   443

     Selected results of operations (in thousands, except per share data) on a
     pro forma basis as if the Acquisition had occurred on January 1, 1996 are
     as follows:

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    (a) Principles of Consolidation

        The consolidated financial statements include the financial statements
        of Venus Exploration, Inc. and its wholly-owned subsidiaries. All
        significant intercompany balances and transactions have been eliminated
        in consolidation. 


                                                                     (Continued)

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

    (b) Cash and Equivalents

        The Company considers all highly liquid investments with an original
        maturity of three months or less when purchased and money market
        accounts to be cash equivalents.

    (c) Oil and Gas Properties

        The Company uses the successful efforts method of accounting for its oil
        and gas operations. Under this method, the costs of unproved leases and
        exploratory wells are initially capitalized pending the results of
        exploration efforts. The costs of unproved properties are assessed
        periodically for impairment, on a field-by-field basis, and a loss is
        recognized to the extent, if any, that the cost of a property has been
        impaired.

        Exploration expenses, including geological and geophysical costs, delay
        rentals, and dry hole costs are charged to expense as incurred.
        Exploratory drilling costs are initially capitalized, but are charged to
        expense if and when the well is determined to be unsuccessful.

        As unproved properties are determined to be productive, the property
        acquisition costs and related exploratory drilling costs of successful
        wells are transferred to proved properties. Development costs of proved
        properties, including producing wells and related facilities and any
        development dry holes, are capitalized. Depreciation, depletion, and
        amortization of the costs of proved properties are provided by the
        unit-of-production method based upon estimates of proved oil and gas
        reserves on a field-by-field basis.

        Capitalized costs of proved properties are periodically reviewed for
        impairment on a field-by-field basis, and, if necessary, an impairment
        provision is recognized to reduce the net carrying amount of such
        properties to their estimated fair values.

    (d) Other Property and Equipment

        Depreciation and amortization of transportation equipment and office
        furniture, fixtures, equipment, and leasehold improvements are computed
        using the straight-line method over the respective estimated useful
        lives. Maintenance, repairs and renewals are charged to operations,
        except that renewals which extend the life of the property are
        capitalized.



                                                                     (Continued)

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

    (e) Income Taxes

        The Company follows the asset and liability method of accounting for
        income taxes. Under this method, deferred tax assets and liabilities are
        recognized for the estimated future tax effects of temporary 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 in effect for the years
        in which those temporary differences are expected to be recovered or
        settled. The effect on deferred tax assets and liabilities of a change
        in tax laws or rates is recognized in income in the period that includes
        the enactment date.

        New Venus' predecessor, Venus Oil Company, elected Subchapter S
        Corporation status for U.S. federal income tax purposes. Under the
        Subchapter S provisions, the stockholders of Venus Oil Company are
        liable for any U.S. federal income taxes related to taxable income of
        Venus Oil Company. Accordingly, no U.S. federal income taxes related to
        the operations of Venus Oil Company are reflected in the accompanying
        consolidated financial statements.

    (f) Revenue Recognition

         The Company records revenue following the entitlement method of
         accounting for gas imbalances. As of December 31, 1997 and 1996, there
         were no significant imbalances. Three customers accounted for
         approximately 22%, 10% and 10% of total consolidated revenues for the
         year ended December 31, 1997. Three customers accounted for
         approximately 31%, 17% and 10% of total consolidated revenues for the
         year ended December 31, 1996. Two customers accounted for approximately
         15% each of total revenues for the year ended December 31, 1995.

    (g) Deferred Financing Costs

        Deferred financing costs at December 31, 1997 and 1996 consist of costs
        associated with obtaining the Company's debt agreements (see note 5)
        which are amortized over the expected term of the related borrowings.

    (h) Other Assets

        Other assets include organizational costs which are amortized over five
        years, a certificate of deposit and investment in equity securities.



                                                                     (Continued)

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

    (i) Hedging Transactions

        The Company enters into commodity derivative contracts for non-trading
        purposes as a hedging strategy to manage commodity prices associated
        with certain oil and gas sales and to reduce the impact of price
        fluctuations. The Company primarily uses price swaps for production on
        properties pledged under the loan agreement discussed in note 5.

        The Company utilizes the hedge or deferral method of accounting for
        commodity derivative financial instruments whereby gains and losses on
        these hedging instruments are recognized and recorded as revenues on the
        statement of operations when the related natural gas or oil has been
        produced, purchased or delivered. As a result, gains and losses on
        commodity financial instruments are generally offset by similar changes
        in the realized prices of natural gas and crude oil. To qualify as
        hedging instruments, these instruments must be highly correlated to
        anticipated future sales such that the Company's exposure to the risks
        of commodity price changes is reduced. While commodity financial
        instruments are intended to reduce the Company's exposure to declines in
        the market price of natural gas and crude oil, the commodity financial
        instruments may also limit the Company's gain from increases in the
        market price of natural gas and crude oil.

        On December 2, 1996, the Company entered into a financial swap, as
        required under one of the loan agreements discussed in note 5, whereby
        the counterparty agrees to pay the Company the difference between the
        floating price and the fixed price for certain volumes of production in
        future months (commencing with January 1997 production) should the
        floating price fall below the negotiated fixed price of $2.0497 per
        mmbtu for natural gas or $19.045 per barrel for oil, respectively.
        Should the floating price exceed the fixed price for natural gas or oil,
        the Company is required to remit the difference to the counterparty. As
        of December 31, 1997 quantities hedged are 81,996 mmbtu's of natural gas
        and 28,656 barrels of oil. This financial swap agreement expires
        December 31, 2001. As of December 31, 1997, the estimated fair value of
        the Company's swap positions was a net receivable of approximately
        $34,000 based upon an estimate of what the Company would receive if the
        contracts were liquidated.

        The Company had no such hedging transactions in 1995.



                                                                     (Continued)

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

    (j) Stock-Based Compensation

        Financial Accounting Standards Board Statement No. 123, Accounting for
        Stock-Based Compensation, allows companies to adopt a fair value based
        method of accounting for stock-based employee compensation plans or to
        continue to use the intrinsic-value based method of accounting
        prescribed by Accounting Principles Board ("APB") Opinion No. 25,
        Accounting for Stock Issued to Employees. The Company has elected to
        account for stock-based compensation under the intrinsic-value method
        under the provisions of APB Opinion No. 25 and related interpretations.
        Under this method, compensation expense is recognized for stock options
        when the exercise price of the options is less than the value attributed
        to the stock on the date of grant.

    (k) Use of Estimates

        The preparation of 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.

    (l) Commitments and Contingencies

        Liabilities for loss contingencies arising from claims, assessments,
        litigation, fines, and penalties are recorded when it is probable that a
        liability has been incurred and that the related amount can be
        reasonably estimated.

    (m) Fair Values of Financial Instruments

        The Company's financial instruments consist primarily of short-term
        trade receivables or payables or issued debt instruments with floating
        interest rates for which management believes fair value approximates
        carrying value. Also see note 2(i).

    (n) Concentration of Credit Risk

        Financial instruments which potentially subject the Company to
        concentrations of credit risk consist primarily of temporary cash
        investments and trade receivables. The Company places its temporary cash
        investments in U.S. Government securities and in other high quality
        financial instruments. The Company's customer base consists primarily of
        independent oil and natural gas producers and purchasers of oil and gas
        products.



                                                                     (Continued)

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

    (o) Earnings (loss) per share

        Basic net earnings (loss) per common share is computed by dividing net
        loss by the weighted average number of common shares outstanding.
        Diluted earnings (loss) per share is computed by assuming the issuance
        of common shares for all dilutive potential common shares outstanding.

        In 1997, the Company adopted Statement of Financial Accounting Standards
        ("FAS") No. 128, "Earnings Per Share" which changed the calculation and
        financial statement presentation of earnings per share. Prior year
        earnings per share amounts have been restated.

        The 3,322,121 shares of common stock issued in 1996 by Venus Energy PLC
        to capitalize Venus Exploration, Inc. have been treated as outstanding
        for all of 1996 for purposes of calculating earnings per share. Earnings
        per share amounts for 1995 have not been presented because the
        predecessor company is a privately-held subchapter S Corporation.

    (p) Reclassifications

        Certain amounts for prior periods have been reclassified in the
        consolidated financial statements to conform to the current
        presentation.

(3) OIL AND GAS PROPERTIES

    Oil and gas properties consist of the following at December 31, 1997 and

     The impairment of oil and gas properties recognized in 1997 and 1996
     includes a write-down of unproved properties of approximately $0 and
     $254,000, respectively, and write-downs of proved properties of
     approximately $1,052,000 and $727,000, respectively. Impairment is
     recognized only if the carrying amount of a property is greater than its
     expected future cash flows. The amount of the impairment is based on the
     estimated fair value of the property.

     Revolving Credit

     In 1997, the Company entered into a loan agreement establishing a
     $20,000,000 revolving line of credit. In December 1997 this agreement
     was restated and amended to increase the credit facility to $50,000,000
     subject to borrowing base determined every six months (April 1 and     
     October 1) by the bank based on the Company's oil and gas reserves which
     are used as security for the loan. Interest on related borrowings is
     based on either of two methods at the option of the Company: the bank's
     prime lending rate or LIBOR plus 1.75%. For balances outstanding at
     December 31, 1997 the Company chose the bank's prime lending rate (8.5%
     at December 31, 1997).

(5)  LONG-TERM DEBT

     Revolving Credit, continued

     A commitment fee of 3/8 of one percent of the undrawn balance is payable
     quarterly. Interest is payable monthly and principal payments are required
     only when the balance outstanding exceeds or is projected to exceed, prior
     to the next borrowing base redetermination date, the borrowing base. Under
     the terms of the restated and amended loan agreement, the initial borrowing
     base is $2,500,000, and it increases to $5,250,000 upon the Company
     obtaining and submitting to the bank certain documents related to a portion
     of the properties securing the loan. As of December 31, 1997, the borrowing
     base was $2,500,000 and the amount drawn by the Company was $500,000
     resulting in an unused borrowing base of $2,000,000.

     Under the terms of the credit facility, the Company is required to maintain
     specified levels of current ratio and tangible net worth. Among other
     matters, the credit facility contains covenants which limit the incurrence
     of additional indebtedness and restrict payments of dividends. At December
     31, 1997, the Company was not in compliance with the tangible net worth
     requirement. The Company obtained a waiver from the lender as of December
     31, 1997 which included a reduction in tangible net worth requirement to
     $7,500,000. However, because of uncertainty regarding the Company's ability
     to remain in compliance with this covenant through the first quarter of
     1998, the outstanding balance has been classified as a current liability in
     the accompanying financial statements.  

     During 1996, the Company entered into a line of credit agreement with a
     bank under which the Company could borrow up to $325,000. Interest on
     amounts borrowed under the line of credit agreement was based on the bank's
     prime rate. During 1996, the Company borrowed and repaid $150,000 under the
     line of credit agreement.

     The line of credit agreement was terminated in October 1996.

     Subsidiary Term Loan

     In October 1996, Venus Development, Inc. (Development) entered into a term
     loan and security agreement with a lender to finance the acquisition and
     development of oil and gas properties. Under the agreement, Development
     could have borrowed up to approximately $2.6 million to finance the
     development of specified oil and gas properties. Such borrowings are
     subject to limitations based on the value of the proved reserves of the
     properties. The borrowings for the specified properties are to be repaid
     over a period not to exceed five years from the date of closing of the
     agreement.



                                                                     (Continued)

(5)  LONG-TERM DEBT, CONTINUED

     Subsidiary Term Loan, continued

     In addition, Development may borrow up to approximately $17.4 million to
     finance the acquisition and development of new properties, subject to
     limitations based on the value of Development's proved reserves
     attributable to properties Development has agreed to include as security
     for such loan. In addition, all of Development's outstanding capital stock
     is pledged as additional security for the borrowings. Development's net
     assets, excluding the term loan, totaled approximately $1,569,000 at
     December 31, 1997. Borrowings for the acquisition and development of new
     properties must be drawn within two years from the date of closing of the
     agreement and must be repaid within seven years from the date of the first
     drawdown. Development is required to pay a drawdown fee to the lender of
     one percent of each drawdown under the agreement. Borrowings under the
     agreement bear interest at the prime rate (8.5% at December 31, 1997) plus
     one percent. As of December 31, 1997, Development had borrowed $1,505,329
     under the agreement. Based on the value of the proved reserves of the
     secured properties, approximately $174,000 was available under the
     agreement at December 31, 1997 to finance the development of the specified
     secured properties.

     Payments on borrowings under the agreement are based on 85 or 90 percent of
     the net revenue, as defined in the agreement, from the secured properties,
     depending on the value of the proved reserves of the secured properties
     relative to the outstanding loan balance.

     Under the agreement, Development is required to assign an overriding
     royalty interest equal to five percent of the Company's net revenue
     interest in the secured properties. The lender had the right to convert the
     value of its overriding royalty interests into equity interests of Venus
     Energy PLC, subject to certain limitations. Development also granted
     warrants to the lender to purchase equity interests in Venus Energy PLC,
     subject to certain limitations. The estimated fair values of the royalty
     interests assigned as of December 31, 1997 and 1996 of $88,718 and $57,500,
     respectively, and the estimated fair value of the warrants issued as of
     December 31, 1996 of $25,000 have been recorded as deferred financing costs
     and are amortized as additional interest over the term of the agreement.

     At December 31, 1996, under the terms of the agreement, the lender had
     warrants and certain conversion rights with respect to these overriding
     royalty interests as described above. During 1997 the agreements creating
     these warrants and conversion rights were amended such that all of lender's
     conversion rights and warrants are exercisable against a pool of shares
     owned by certain of the Company's shareholders. Neither the Company nor
     Development has any obligations as of December 31, 1997, with respect to
     the lender's conversion rights or warrants.



                                                                     (Continued)

(5)  LONG-TERM DEBT, CONTINUED

     Subsidiary Term Loan, continued

     The lender shall have the right to purchase at competitive market prices
     all crude oil or natural gas produced from or allocable to the secured
     properties including, without limitation, all of the production
     attributable to Development's net revenue interest in the secured
     properties subject to the rights of other working interest and royalty
     interest owners. The term of the purchase and sale agreement extends seven
     years with three additional one-year options.

     The loan agreement requires, among other matters, maintenance of a minimum
     working capital amount. Development was either in compliance with, or had
     obtained waivers with respect to, these covenants as of December 31, 1997.

(6)  INCOME TAXES

     No provision for income taxes has been recorded for the years ended
     December 31, 1997 and 1996 due to the losses recorded by the Company. The
     Company's predecessor, Venus Oil Company, elected Subchapter S Corporation
     status for U.S. federal income tax purposes. Under the Subchapter S
     provisions, the stockholders of Venus Oil Company are liable for any U.S.
     federal income taxes related to taxable income of Venus Oil Company.
     Accordingly, no U.S. federal income taxes related to the operations of
     Venus Oil Company are reflected in the accompanying consolidated financial
     statements.

     The tax effects of temporary differences that give rise to significant
     portions of the deferred tax assets and deferred tax liabilities at
     December 31, 1997 and 1996 are presented below.

(6)  INCOME TAXES, CONTINUED

     The valuation allowance for deferred tax assets as of January 1, 1997 and
     1996 was $1,271,000 and $0, respectively. The net change in the total
     valuation allowance for the years ended December 31, 1997 and 1996 was an
     increase of $426,000 and $1,271,000, respectively. In assessing the
     realizability of deferred tax assets, management considers whether it is
     more likely than not that some portion or all of the deferred tax assets
     will not be realized. The ultimate realization of deferred tax assets is
     dependent upon the generation of future taxable income during the periods
     in which those temporary differences become deductible. The net deferred
     tax asset at December 31, 1997 and 1996 has been offset entirely by a
     valuation allowance due to the uncertainty of the ultimate realization of
     such benefits.

     As of December 31, 1997, the Company had an estimated net operating loss
     carryforward for U.S. federal income tax purposes of approximately
     $4,311,000 which is available to offset future taxable income, if any,
     through 2012. The utilization of the Company's net operating loss
     carryforwards may be limited as a result of the transactions referred to in
     note 1.

     The Company intends to liquidate Venus Energy PLC, an inactive U.K.
     subsidiary. Management of the Company believes that there will be no
     significant tax obligations in the United Kingdom as a result of such
     liquidation.

(7)  SHAREHOLDERS'  EQUITY

     The New Venus Exploration, Inc. ("New Venus") was formed to be the
     successor entity to certain oil and gas exploration, development, and
     production operations of Venus Energy PLC and Venus Oil Company as
     described below. Venus Energy PLC and subsidiaries were organized in 1996
     to acquire certain oil and gas exploration, development, and production
     operations of Venus Oil Company. Venus Energy PLC and subsidiaries
     commenced operations effective July 1, 1996 upon the transfer of certain
     oil and gas properties from Venus Oil Company.

     All share and per share information related to shares issued to effect the
     original organization transactions described herein (the "convertible
     shares") have been restated to present their equivalent number of shares of
     the Company's common stock.

     Venus Energy PLC was incorporated on May 15, 1996 as a public limited
     company in the United Kingdom. Upon formation, the shareholders of Venus
     Oil Company contributed $26,740 to Venus Energy PLC in exchange for
     2,910,077 shares.



                                                                     (Continued)

(7)  SHAREHOLDERS'  EQUITY, CONTINUED

     Venus Exploration, Inc. ("Old Venus") was incorporated in the state of
     Texas on May 16, 1996 as a wholly-owned subsidiary of Venus Energy PLC.
     Upon formation, Old Venus paid $22,500 to Venus Oil Company for an option
     that would allow Old Venus to acquire certain oil and gas properties from
     Venus Oil Company for $2,000,000.

     Venus Energy PLC raised $4,955,000 from the sale of 247,750 convertible
     redeemable preference shares through a private offering to new investors.
     Venus Energy PLC contributed substantially all of the proceeds of the
     private offering to Old Venus. Effective July 1, 1996, Old Venus exercised
     its option to acquire certain oil and gas properties from Venus Oil Company
     for $2,000,000. Venus Oil Company then paid $1,000,000 to acquire 412,044
     convertible shares of Venus Energy PLC. Venus Energy PLC subsequently
     contributed substantially all of the proceeds from the sale of the shares
     to Old Venus.

     In September 1996, Venus Development, Inc. was incorporated in the State
     of Texas as a wholly-owned subsidiary of Old Venus. Certain oil and gas
     properties were transferred from Old Venus to Venus Development, Inc.
     The oil and gas properties and the stock of Venus Development, Inc. have
     been pledged as security for borrowings under one of the debt agreements
     described in note 5.

     Old Venus acquired oil and gas properties with a net financial statement
     carrying amount of $532,820 from Venus Oil Company for $2,022,500 in 1996.
     In addition, Old Venus paid Venus Oil Company $111,908 for certain other
     assets with a net financial statement carrying amount of $67,704. The
     properties and other assets transferred from Venus Oil Company have been
     recorded by Old Venus at the net carrying amounts of such properties and
     other assets in the financial statements of Venus Oil Company at the time
     of transfer. The amounts paid to Venus Oil Company for the properties and
     other assets and the remaining net assets of Venus Oil Company which were
     not transferred to Venus Energy PLC or its subsidiaries of $1,430,555,
     including cash of $481,280, have been recorded as distributions in the 1996
     statement of shareholder's equity.

     As described in note 1, in a series of related transactions in 1997, the
     shareholders of Venus Energy PLC, became the shareholders of New Venus, and
     New Venus succeeded to the assets of Old Venus. The shareholders of Venus
     Energy PLC exchanged their shares for the outstanding shares of New Venus,
     and the assets and liabilities of Old Venus were transferred to the New
     Venus. In conjunction with the Acquisition described below the 247,750
     convertible redeemable preference shares were converted into 2,041,674
     common shares.


                                                                     (Continued)

(7)  SHAREHOLDERS'  EQUITY, CONTINUED

     As described in note 1, on May 21, 1997, the Company, then known as Xplor
     Corporation ("Xplor"), acquired substantially all of the assets and
     liabilities of The New Venus Exploration, Inc. ("New Venus"), a Texas
     corporation, in exchange for 5,626,473 shares of Xplor's previously
     authorized and unissued shares of common stock and warrants to purchase
     272,353 additional shares of common stock. Simultaneously, Xplor acquired
     certain oil and gas properties of two wholly-owned affiliates of Lomak
     Petroleum, Inc. (together, "Lomak") in exchange for 2,037,171 shares of
     Xplor's previously authorized and unissued shares of common stock and
     warrants to purchase 272,353 additional shares of common stock. At the same
     time, Lomak acquired from an existing stockholder of Xplor 97,008 shares of
     common stock. On June 4, 1997 Xplor changed its name to Venus Exploration,
     Inc.

(8)  RELATED PARTY TRANSACTIONS

      Certain officers and shareholders of the Company have working interests in
      certain properties operated by the Company. In addition, they participate
      with the Company in developing certain properties. Management believes
      these transactions are conducted on a basis similar to transactions with
      third parties.

      The Company receives $2,500 per month from Venus Oil Company, which is
      owned by certain shareholders of the Company, for overhead reimbursement
      of certain administrative costs. Prior to 1997, the Company had a program
      whereby certain officers and employees were awarded overriding royalty
      interests in certain properties prior to their development. The value of
      such interests at the time of award was not significant.

      At December 31, 1997, trade accounts payable include $68,762 due to Venus
      Oil Company. Included in trade accounts receivable at December 31, 1996 is
      $6,848 due from Venus Oil Company.

(9)  STOCK OPTIONS

      The Company has adopted an incentive plan that authorizes the grant of
      awards to employees, consultants, contractors and non-employee directors.
      The awards to employees, consultants and contractors can be in the form of
      options, stock appreciation rights, stock or cash. The awards to
      non-employee directors are limited to grants for shares of the Company's
      common stock. The plan is administered by the compensation committee of
      the Company's board of directors.



                                                                     (Continued)

(9)  STOCK OPTIONS, CONTINUED

      The number of shares of the Company's common stock that is subject to the
      incentive plan is 10% of the Company's outstanding shares up to a maximum
      of 1,500,000 shares, less the number of shares that were subject to
      previous plans of the Company and that are not assumed by the current
      incentive plan. As of December 31, 1997, the Company had reserved 653,365
      shares for the incentive plan.

      As of December 31, 1997 there had been no awards under the 1997 incentive
      plan, however, the Company assumed certain outstanding stock options of
      Xplor as a result of the Acquisition.

</TABLE>

     The Company accounts for its stock-based compensation plans under APB
     Opinion No. 25, under which no compensation expense is recognized when
     options are granted with an exercise price equal to the fair value of the
     Company's common stock on the date of grant. In addition, the Company
     adopted Statement of Financial Accounting Standards No. 123, "Accounting
     for Stock Based Compensation" ("FAS No. 123") for disclosure purposes in
     1996. The Company granted no stock options during 1997 or 1995. Options
     issued during 1996 were issued at a strike price below fair market price.
     The compensation expense reported by the Company was equal to the expense
     that would have been recognized under FAS No. 123.

     The Company granted options to certain directors to acquire 221,474 shares
     at an exercise price of $0.01 per share. The Company has recognized
     compensation expense and a corresponding increase in additional
     paid-in-capital of $252,002 in 1997 and $283,430 in 1996 related to the
     these options. The Company has also granted options to special counsel to
     acquire 41,204 shares. The compensation expense reported by the Company
     approximates the expense that would have been recognized under FAS No. 123.




                                                                     (Continued)

(10) EMPLOYEE BENEFIT PLAN

     The Company has a Profit Sharing 401(k) Plan (the Plan). Benefits under the
     Plan are based on the participants vested interests in the value of their
     respective accounts at the time the benefits become payable as a result of
     retirement, separation from service, or other events. Eligible participants
     include all Company employees who have reached age 21 and have completed
     three months of service with the Company. Employees may elect to contribute
     a portion of their base compensation to the Plan. The Company may make
     matching contributions on behalf of the participants based on actual
     participant contributions. Employer contributions are discretionary. The
     Company made contributions to the plan of $7,734, $4,643, and $5,010 for
     1997, 1996, and 1995, respectively.

     (c)  Reserve Quantity Information

          The following table presents the Company's estimate of its proved oil
          and gas reserves, all of which are located in the United States. The
          Company emphasizes that reserve estimates are inherently imprecise 
          and that estimates of new discoveries are more imprecise than those of
          producing oil and gas properties. Accordingly, the estimates are
          expected to change as future information becomes available. The
          estimates have been prepared by independent petroleum reservoir
          engineers, in conjunction with the Company's internal petroleum
          reservoir engineers.

       These estimates were computed by applying appropriate current oil and
       natural gas prices to estimated future production of proved oil and gas
       reserves over the economic lives of the reserves and assuming
       continuation of existing economic conditions. Year ended 1997
       calculations were made utilizing average prices for oil and natural gas
       that existed at December 31, 1997 of $17.56 per barrel and $2.49 per Mcf,
       respectively. Income taxes are computed by applying the statutory federal
       income tax rate to the net cash inflows relating to proved oil and gas
       reserves less the tax bases of the properties involved and giving effect
       to net operating loss carryforwards, tax credits and allowances relating
       to such properties. The reserve volumes provided by the independent
       petroleum engineers are estimates only and should not be construed as
       exact quantities. These reserves may or may not be recovered and may
       increase or decrease as result of future operations of the Company and
       changes in market conditions.

Transfer Agents and registered by one of such Registrars.

         Section 5.3      Transfers of Shares.  Shares of the Corporation may
be transferred by delivery of the certificates therefor, accompanied either by
an assignment in writing on the back of the certificates or by written power of
attorney to sell, assign and transfer the same, signed by the record holder
thereof; but no transfer shall affect the right of the Corporation to pay any
dividend upon the shares to the holder of record thereof, or to treat the
holder of record as the holder in fact thereof for all purposes, and no
transfer shall be valid, except between the parties thereto, until such
transfer shall have been made upon the books of the Corporation.

         Section 5.4      Lost Certificates.  In case any certificate for
shares of the Corporation shall be lost, stolen or destroyed, the Board, in its
discretion, or any Transfer Agent thereunto duly authorized by the Board, may
authorize the issue of a substitute certificate in place of the certificate so
lost, stolen or destroyed, and may cause such substitute certificate to be
countersigned by the appropriate Registrar (if any); provided, that, in each
such case, the applicant for a substituted certificate shall furnish to the
Corporation and to such of its Transfer Agents and Registrars as may require
the same, evidence to their satisfaction, in their discretion, if the loss,
theft or destruction of such certificate and of the ownership thereof, and also
such security or indemnity as may then be required.

         THIS WARRANT AND THE SHARES OF COMMON STOCK  ISSUABLE UPON THE
EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER EITHER THE SECURITIES ACT OF
1933 (THE "ACT") OR APPLICABLE STATE SECURITIES LAWS (THE "STATE ACTS") AND
SHALL NOT BE SOLD, PLEDGED, HYPOTHECATED, DONATED OR OTHERWISE TRANSFERRED

            Void after 5:00 p.m. New York Time, on October 23, 2000.
               Warrant to Purchase 10,000 Shares of Common Stock.



                        WARRANT TO PURCHASE COMMON STOCK

                                       OF

                               XPLOR CORPORATION



                 This is to Certify That, FOR VALUE RECEIVED, Martin A. Bell or
assigns ("Holder"), is entitled to purchase, subject to the provisions of this
Warrant, from XPLOR CORPORATION, a Delaware corporation ("Company"), Ten
Thousand (10,000) fully paid, validly issued and nonassessable shares of Common
Stock, par value $.01 per share, of the Company ("Common Stock") at a price of
$2.00 per share at any time or from time to time during the period from October
23, 1995 to October 23, 2000, but not later than 5:00 p.m. New York City Time,
on October 23, 2000.  The number of shares of Common Stock to be received upon
the exercise of this Warrant and the price to be paid for each share of Common
Stock may be adjusted from time to time as hereinafter set forth.  The shares
of Common Stock deliverable upon such exercise, and as adjusted from time to
time, are hereinafter sometimes referred to as "Warrant Shares" and the
exercise price of a share of Common Stock in effect at any time and as adjusted
from time to time is hereinafter sometimes referred to as the "Exercise Price".

                 (a)      EXERCISE OF WARRANT.

                          (1)     This Warrant may be exercised in whole or in
part at any time or from time to time on or after October 23, 1995 and until
October 23, 2000 (the "Exercise Period"), subject to the provisions of Section
(j)(2) hereof; provided, however, that (i) if either such day is a day on which
banking institutions in the State of New York are authorized by law to close,
then on the next succeeding day which shall not be such a day, and (ii) in the
event of
<PAGE>   3
any merger, consolidation or sale of substantially all the assets of the
Company as an entirety, resulting in any distribution to the Company's
stockholders, prior to October 23, 2000, the Holder shall have the right to
exercise this Warrant commencing at such time through October 23, 2000 into the
kind and amount of shares of stock and other securities and property (including
cash) receivable by a holder of the number of shares of Common Stock into which
this Warrant might have been exercisable immediately prior thereto.  This
Warrant may be exercised by presentation and surrender hereof to the Company at
its principal office, or at the office of its stock transfer agent, if any,
with the Purchase Form annexed hereto duly executed and accompanied by payment
of the Exercise Price for the number of Warrant Shares specified in such form.
As soon as practicable after each such exercise of the Warrants, but not later
than seven (7) days from the date of such exercise, the Company shall issue and
deliver to the Holder a certificate or certificate for the Warrant Shares
issuable upon such exercise, registered in the name of the Holder or its
designee.  If this Warrant should be exercised in part only, the Company shall,
upon surrender of this Warrant for cancellation, execute and deliver a new
Warrant evidencing the rights of the Holder thereof to purchase the balance of
the Warrant Shares purchasable thereunder.  Upon receipt by the Company of this
Warrant at its office, or by the stock transfer agent of the Company at its
office, in proper form for exercise, the Holder shall be deemed to be the
holder of record of the shares of Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or that certificates representing such shares of Common Stock shall not
then be physically delivered to the Holder.

                 (2)      At any time during the Exercise Period, the Holder
may, at its option, exchange this Warrant, in whole or in part (a "Warrant
Exchange"), into the number of Warrant Shares determined in accordance with
this Section (a)(2), by surrendering this Warrant at the principal office of
the Company or at the office of its stock transfer agent, accompanied by a
notice stating such Holder's intent to effect such exchange, the number of
Warrant Shares to be exchanged and the date on which the Holder requests that
such Warrant Exchange occur (the "Notice of Exchange").  The Warrant Exchange
shall take place on the date specified in the Notice of Exchange or, if later,
the date the Notice of Exchange is received by the Company (the "Exchange
Date").  Certificates for the shares issuable upon such Warrant Exchange and,
if applicable, a new warrant of like tenor evidencing the balance of the shares
remaining subject to this Warrant, shall be issued as of the Exchange Date and
delivered to the Holder within seven (7) days following the Exchange Date.  In
connection with any Warrant Exchange, this Warrant shall represent the right to
subscribe for and acquire the number of Warrant Shares (rounded to the next
highest integer) equal to (i) the number of Warrant Shares specified by the
Holder in its Notice of Exchange (the "Total Number") less (ii) the number of
Warrant Shares equal to the quotient obtained by dividing (A) the product of
the Total Number and the existing Exercise Price by (B) the current market
value of a share of Common Stock.  Current market value shall have the meaning
set forth Section (c) below, except that for purposes hereof, the date of
exercise, as used in such Section (c), shall mean the Exchange Date.

                 (b)      RESERVATION AND LISTING OF SHARES.  The Company shall
at all times reserve for issuance and/or delivery upon exercise of this Warrant
such number of shares of its Common Stock as shall be required for issuance and
delivery upon exercise of the Warrants.
<PAGE>   4
                 (c)      FRACTIONAL SHARES.  No fractional shares or script
representing fractional shares shall be issued upon the exercise of this
Warrant.  With respect to any fraction of a share called for upon any exercise
hereof, the Company shall pay to the Holder an amount in cash equal to such
fraction multiplied by the current market value of a share, determined as
follows:

                          (1)     If the Common Stock is listed on a National
                 Securities Exchange or admitted to unlisted trading privileges
                 on such exchange or listed for trading on the Nasdaq system,
                 the current market value shall be the last reported sale price
                 of the Common Stock on such exchange or system on the last
                 business day prior to the date of exercise of this Warrant or
                 if no such sale is made on such day, the average closing bid
                 and asked prices for such day on such exchange or system; or

                          (2)     If the Common Stock is not so listed or
                 admitted to unlisted trading privileges, the current market
                 value shall be the mean of the last reported bid and asked
                 prices reported by the National Quotation Bureau, Inc. on the
                 last business day prior to the date of the exercise of this
                 Warrant; or

                          (3)     If the Common Stock is not so listed or
                 admitted to unlisted trading privileges and bid and asked
                 prices are not so reported, the current market value shall be
                 an amount, not less than book value thereof as at the end of
                 the most recent fiscal year of the Company ending prior to the
                 date of the exercise of the Warrant, determined in such
                 reasonable manner as may be prescribed by the Board of
                 Directors of the Company.

                 (d)      EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT.
This Warrant is exchangeable, without expense, at the option of the Holder,
upon presentation and surrender hereof to the Company or at the office of its
stock transfer agent, if any, for other warrants of different denominations
entitling the holder thereof to purchase in the aggregate the same number of
shares of Common Stock purchasable hereunder.  Upon surrender of this Warrant
to the Company at its principal office or at the office of its stock transfer
agent, if any, with the Assignment Form annexed hereto duly executed and funds
sufficient to pay any transfer tax, the Company shall, without charge, execute
and deliver a new Warrant in the name of the assignee named in such instrument
of assignment and this Warrant shall promptly be cancelled.  This Warrant may
be divided or combined with other warrants which carry the same rights upon
presentation hereof at the principal office of the Company or at the office of
its stock transfer agent, if any, together with a written notice specifying the
names and denominations in which new Warrants are to be issued and signed by
the Holder hereof.  The term "Warrant" as used herein includes any Warrants
into which this Warrant may be divided or exchanged.  Upon receipt by the
Company of evidence satisfactory to it of the loss, theft, destruction or
mutilation of this Warrant, and (in the case of loss, theft or destruction) of
reasonably satisfactory indemnification, and upon surrender and cancellation of
this Warrant, if mutilated, the Company will execute and deliver a new Warrant
of like tenor and date.  Any such new Warrant executed and delivered shall
constitute an additional contractual obligation on the part of the Company,
whether or not this Warrant so lost, stolen, destroyed, or mutilated shall be
at any time enforceable by anyone.
<PAGE>   5
                 (e)      RIGHTS OF THE HOLDER.  The Holder shall not, by
virtue hereof, be entitled to any rights of a shareholder in the Company,
either at law or equity, and the rights of the Holder are limited to those
expressed in the Warrant and are not enforceable against the Company except to
the extent set forth herein.

                 (f)      ANTI-DILUTION PROVISIONS.  The Exercise Price in
effect at any time and the number and kind of securities purchasable upon the
exercise of the Warrants shall be subject to adjustment from time to time upon
the happening of certain events as follows:

                          (1)     In case the Company shall (i) declare a
                 dividend or make a distribution on its outstanding shares of
                 Common Stock in shares of Common Stock, (ii) subdivide or
                 reclassify its outstanding shares of Common Stock into a
                 greater number of shares, or (iii) combine or reclassify its
                 outstanding shares of Common Stock into a smaller number of
                 shares, the Exercise Price in effect at the time of the record
                 date for such dividend or distribution or of the effective
                 date of such subdivision, combination or reclassification
                 shall be adjusted so that it shall equal the price determined
                 by multiplying the Exercise Price by a fraction, the
                 denominator of which shall be the number of shares of Common
                 Stock outstanding after giving effect to such action, and the
                 numerator of which shall be the number of shares of Common
                 Stock outstanding immediately prior to such action.  Such
                 adjustment shall be made successively whenever any event
                 listed above shall occur.

                          (2)     In case the Company shall fix a record date
                 for the issuance of rights or warrants to all holders of its
                 Common Stock entitling them to subscribe for or purchase
                 shares of Common Stock (or securities convertible into Common
                 Stock) at a price (the "Subscription Price") (or having a
                 conversion price per share) less than the current market price
                 of the Common Stock (as defined in Subsection (8) below) on
                 the record date mentioned below, or less than the Exercise
                 Price on such record date the Exercise Price shall be adjusted
                 so that the same shall equal the lower of (i) the price
                 determined by multiplying the Exercise Price in effect
                 immediately prior to the date of such issuance by a fraction,
                 the numerator of which shall be the sum of the number of
                 shares of Common Stock outstanding on the record date
                 mentioned below and the number of additional
<PAGE>   6
                 shares of Common Stock which the aggregate offering price of
                 the total number of shares of Common Stock so offered (or the
                 aggregate conversion price of the convertible securities so
                 offered) would purchase at such current market price per share
                 of the Common Stock, and the denominator of which shall be the
                 sum of the number of shares of Common Stock outstanding on
                 such record date and the number of additional shares of Common
                 Stock offered for subscription or purchase (or into which the
                 convertible securities so offered are convertible) or (ii) in
                 the event the Subscription Price is equal to or higher than
                 the current market price but is less than the Exercise Price,
                 the price determined by multiplying the Exercise Price in
                 effect immediately prior to the date of issuance by a
                 fraction, the numerator of which shall be the sum of the
                 number of shares outstanding on the record date mentioned
                 below and the number of additional shares of Common Stock
                 which the aggregate offering price of the total number of
                 shares of Common Stock so offered (or the aggregate conversion
                 price of the convertible securities so offered) would purchase
                 at the Exercise Price in effect immediately prior to the date
                 of such issuance, and the denominator of which shall be the
                 sum of the number of shares of Common Stock outstanding on the
                 record date mentioned below and the number of additional
                 shares of Common Stock offered for subscription or purchase
                 (or into which the convertible securities so offered are
                 convertible).  Such adjustment shall be made successively
                 whenever such rights or warrants are issued and shall become
                 effective immediately after the record date for the
                 determination of shareholders entitled to receive such rights
                 or warrants; and to the extent that shares of Common Stock are
                 not delivered (or securities convertible into Common Stock are
                 not delivered) after the expiration of such rights or warrants
                 the Exercise Price shall be readjusted to the Exercise Price
                 which would then be in effect had the adjustments made upon
                 the issuance of such rights or warrants been made upon the
                 basis of delivery of only the number of shares of Common Stock
                 (or securities convertible into Common Stock) actually
                 delivered.

                          (3)     In case the Company shall hereafter
                 distribute to the holders of its Common Stock evidences of its
                 indebtedness or assets (excluding cash dividends or
                 distributions and dividends or distributions referred to in
                 Subsection (1) above) or subscription rights or warrants
                 (excluding those referred to in Subsection (2) above), then in
                 each such case the Exercise Price in effect thereafter shall
                 be determined by multiplying the Exercise Price in effect
                 immediately prior thereto by a fraction, the numerator of
                 which shall be the total number of shares of Common Stock
                 outstanding multiplied by the current market price per share
                 of Common Stock (as defined in Subsection (8) below), less the
                 fair market value (as determined by the Company's Board of
                 Directors) of said assets or evidences of indebtedness so
                 distributed or of such rights or warrants, and the denominator
                 of which shall be the total number of shares of Common Stock
                 outstanding multiplied by such current market price per share
                 of Common Stock.  Such adjustment shall be made successively
                 whenever such a record date is fixed.  Such adjustment shall
                 be made whenever any such distribution is made and shall
                 become effective immediately after the record date for the
                 determination of shareholders entitled to receive such
                 distribution.

                          (4)     In case the Company shall issue shares of its
                 Common Stock [excluding shares issued (i) in any of the
                 transactions described in Subsection (1) above, (ii) upon
                 exercise of options granted to the Company's employees or
                 directors under a plan or plans adopted by the Company's Board
                 of Directors, if such shares would otherwise be included in
                 this Subsection (4), (but only to the extent that the
                 aggregate number of shares excluded hereby and issued after
                 the date hereof, shall not exceed 5% of the Company's Common
                 Stock outstanding at the time of any issuance), (iii) upon
                 exercise of options and warrants outstanding at October 23,
                 1995, and this Warrant (iv) to shareholders of any corporation
                 which merges into the Company in proportion to their stock
                 holdings of such
<PAGE>   7
                 corporation immediately prior to such merger, upon such
                 merger, or (v) issued in a bona fide public offering pursuant
                 to a firm commitment underwriting, but only if no adjustment
                 is required pursuant to any other specific subsection of this
                 Section (f) (without regard to Subsection (9) below) with
                 respect to the transaction giving rise to such rights] for a
                 consideration per share (the "Offering Price") less than the
                 current market price per share [as defined in Subsection (8)
                 below] on the date the Company fixes the offering price of
                 such additional shares or less than the Exercise Price, the
                 Exercise Price shall be adjusted immediately thereafter so
                 that it shall equal the lower of (i) the price determined by
                 multiplying the Exercise Price in effect immediately prior
                 thereto by a fraction, the numerator of which shall be the sum
                 of the number of shares of Common Stock outstanding
                 immediately prior to the issuance of such additional shares
                 and the number of shares of Common Stock which the aggregate
                 consideration received [determined as provided in Subsection
                 (7) below] for the issuance of such additional shares would
                 purchase at such current market price per share of Common
                 Stock, and the denominator of which shall be the number of
                 shares of Common Stock outstanding immediately after the
                 issuance of such additional shares or (ii) in the event the
                 Offering Price is equal to or higher than the current market
                 price per share but less than the Exercise Price, the price
                 determined by multiplying the Exercise Price in effect
                 immediately prior to the date of issuance by a fraction, the
                 numerator of which shall be the number of shares of Common
                 Stock outstanding immediately prior to the issuance of such
                 additional shares and the number of shares of Common Stock
                 which the aggregate consideration received [determined as
                 provided in subsection (7) below] for the issuance of such
                 additional shares would purchase at the Exercise Price in
                 effect immediately prior to the date of such issuance, and the
                 denominator of which shall be the number of shares of Common
                 Stock outstanding immediately after the issuance of such
                 additional shares. Such adjustment shall be made successively
                 whenever such an issuance is made.

                          (5)     In case the Company shall issue any
                 securities convertible into or exchangeable for its Common
                 Stock [excluding securities issued in transactions described
                 in Subsections (2) and (3) above] for a consideration per
                 share of Common Stock (the "Conversion Price") initially
                 deliverable upon conversion or exchange of such securities
                 [determined as provided in Subsection (7) below] less than the
                 current market price per share [as defined in Subsection (8)
                 below] in effect immediately prior to the issuance of such
                 securities, or less than the Exercise Price, the Exercise
                 Price shall be adjusted immediately thereafter so that it
                 shall equal the lower of (i) the price determined by
                 multiplying the Exercise Price in effect immediately prior
                 thereto by a fraction, the numerator of which shall be the sum
                 of the number of shares of Common Stock outstanding
                 immediately prior to the issuance of such securities and the
                 number of shares of Common Stock which the aggregate
                 consideration received [determined as provided in Subsection
                 (7) below] for such securities would purchase at such current
                 market price per share of Common Stock, and the denominator of
                 which shall be the sum of the number of shares of Common Stock
                 outstanding
<PAGE>   8
                 immediately prior to such issuance and the maximum number of
                 shares of Common Stock of the Company deliverable upon
                 conversion of or in exchange for such securities at the
                 initial conversion or exchange price or rate or (ii) in the
                 event the Conversion Price is equal to or higher than the
                 current market price per share but less than the Exercise
                 Price, the price determined by multiplying the Exercise Price
                 in effect immediately prior to the date of issuance by a
                 fraction, the numerator of which shall be the sum of the
                 number of shares outstanding immediately prior to the issuance
                 of such securities and the number of shares of Common Stock
                 which the aggregate consideration received [determined as
                 provided in subsection (7) below] for such securities would
                 purchase at the Exercise Price in effect immediately prior to
                 the date of such issuance, and the denominator of which shall
                 be the sum of the number of shares of Common Stock outstanding
                 immediately prior to the issuance of such securities and the
                 maximum number of shares of Common Stock of the Company
                 deliverable upon conversion of or in exchange for such
                 securities at the initial conversion or exchange price or
                 rate.  Such adjustment shall be made successively whenever
                 such an issuance is made.

                          (6)     Whenever the Exercise Price payable upon
                 exercise of each Warrant is adjusted pursuant to Subsections
                 (1), (2), (3), (4) and (5) above, the number of Shares
                 purchasable upon exercise of this Warrant shall simultaneously
                 be adjusted by multiplying the number of Shares initially
                 issuable upon exercise of this Warrant by the Exercise Price
                 in effect on the date hereof and dividing the product so
                 obtained by the Exercise Price, as adjusted.

                          (7)     For purposes of any computation respecting
                 consideration received pursuant to Subsections (4) and (5)
                 above, the following shall apply:

                                  (A)      in the case of the issuance of
                          shares of Common Stock for cash, the consideration
                          shall be the amount of such cash, provided that in no
                          case shall any deduction be made for any commissions,
                          discounts or other expenses incurred by the Company
                          for any underwriting of the issue or otherwise in
                          connection therewith;

                                  (B)      in the case of the issuance of
                          shares of Common Stock for a consideration in whole
                          or in part other than cash, the consideration other
                          than cash shall be deemed to be the fair market value
                          thereof as determined in good faith by the Board of
                          Directors of the Company (irrespective of the
                          accounting treatment thereof), whose determination
                          shall be conclusive; and

                                  (C)      in the case of the issuance of
                          securities convertible into or exchangeable for
                          shares of Common Stock, the aggregate consideration
                          received therefor shall be deemed to be the
                          consideration received by the Company for the
                          issuance of such securities plus the additional
                          minimum consideration, if any, to be received by the
                          Company upon the conversion
<PAGE>   9
                          or exchange thereof [the consideration in each case
                          to be determined in the same manner as provided in
                          clauses (A) and (B) of this Subsection (7)].

                          (8)     For the purpose of any computation under
                 Subsections (2), (3), (4) and (5) above, the current market
                 price per share of Common Stock at any date shall be deemed to
                 be the lower of (i) the average of the daily closing prices
                 for 30 consecutive business days before such date or (ii) the
                 closing price on the business day immediately preceding such
                 date.  The closing price for each day shall be the last sale
                 price regular way or, in case no such reported sale takes
                 place on such day, the average of the last reported bid and
                 asked prices regular way, in either case on the principal
                 national securities exchange on which the Common Stock is
                 admitted to trading or listed, or if not listed or admitted to
                 trading on such exchange, the average of the highest reported
                 bid and lowest reported asked prices as reported by Nasdaq, or
                 other similar organization if Nasdaq is no longer reporting
                 such information, or if not so available, the fair market
                 price as determined by the Board of Directors.

                          (9)     No adjustment in the Exercise Price shall be
                 required unless such adjustment would require an increase or
                 decrease of at least five cents ($0.05) in such price;
                 provided, however, that any adjustments which by reason of
                 this Subsection (9) are not required to be made shall be
                 carried forward and taken into account in any subsequent
                 adjustment required to be made hereunder.  All calculations
                 under this Section (f) shall be made to the nearest cent or to
                 the nearest one-hundredth of a share, as the case may be.
                 Anything in this Section (f) to the contrary notwithstanding,
                 the Company shall be entitled, but shall not be required, to
                 make such changes in the Exercise Price, in addition to those
                 required by this Section (f), as it shall determine, in its
                 sole discretion, to be advisable in order that any dividend or
                 distribution in shares of Common Stock, or any subdivision,
                 reclassification or combination of Common Stock, hereafter
                 made by the Company shall not result in any Federal Income tax
                 liability to the holders of Common Stock or securities
                 convertible into Common Stock (including Warrants).

                          (10)    Whenever the Exercise Price is adjusted, as
                 herein provided, the Company shall promptly but no later than
                 10 days after any request for such an adjustment by the
                 Holder, cause a notice setting forth the adjusted Exercise
                 Price and adjusted number of Shares issuable upon exercise of
                 each Warrant, and, if requested, information describing the
                 transactions giving rise to such adjustments, to be mailed to
                 the Holders at their last addresses appearing in the Warrant
                 Register, and shall cause a certified copy thereof to be
                 mailed to its transfer agent, if any.  In the event the
                 Company does not provide the Holder with such notice and
                 information within 10 days of a request by the Holder, then
                 notwithstanding the provisions of this Section (f), the
                 Exercise Price shall be immediately adjusted to equal the
                 lowest Offering Price, Subscription Price or Conversion Price,
                 as applicable, since the date of this Warrant, and the number
                 of shares issuable upon exercise of this Warrant shall be
                 adjusted accordingly.  The Company may retain
<PAGE>   10
                 a firm of independent certified public accountants selected by
                 the Board of Directors (who may be the regular accountants
                 employed by the Company) to make any computation required by
                 this Section (f), and a certificate signed by such firm shall
                 be conclusive evidence of the correctness of such adjustment.

                          (11)    In the event that at any time, as a result of
                 an adjustment made pursuant to Subsection (1) above, the
                 Holder of this Warrant thereafter shall become entitled to
                 receive any shares of the Company, other than Common Stock,
                 thereafter the number of such other shares so receivable upon
                 exercise of this Warrant shall be subject to adjustment from
                 time to time in a manner and on terms as nearly equivalent as
                 practicable to the provisions with respect to the Common Stock
                 contained in Subsections (1) to (9), inclusive above.

                          (12)    Irrespective of any adjustments in the
                 Exercise Price or the number or kind of shares purchasable
                 upon exercise of this Warrant, Warrants theretofore or
                 thereafter issued may continue to express the same price and
                 number and kind of shares as are stated in the similar
                 Warrants initially issuable pursuant to this Agreement.



                 (g)      OFFICER'S CERTIFICATE.  Whenever the Exercise Price
shall be adjusted as required by the provisions of the foregoing Section, the
Company shall forthwith file in the custody of its Secretary or an Assistant
Secretary at its principal office and with its stock transfer agent, if any, an
officer's certificate showing the adjusted Exercise Price determined as herein
provided, setting forth in reasonable detail the facts requiring such
adjustment, including a statement of the number of additional shares of Common
Stock, if any, and such other facts as shall be necessary to show the reason
for and the manner of computing such adjustment.  Each such officer's
certificate shall be made available at all reasonable times for inspection by
the holder or any holder of a Warrant executed and delivered pursuant to
Section (a) and the Company shall, forthwith after each such adjustment, mail a
copy by certified mail of such certificate to the Holder or any such holder.

                 (h)      NOTICES TO WARRANT HOLDERS.  So long as this Warrant
shall be outstanding, (i) if the Company shall pay any dividend or make any
distribution upon the Common Stock or (ii) if the Company shall offer to the
holders of Common Stock for subscription or purchase by them any share of any
class or any other rights or (iii) if any capital reorganization of the
Company, reclassification of the capital stock of the Company, consolidation or
merger of the Company with or into another corporation, sale, lease or transfer
of all or substantially all of the property and assets of the Company to
another corporation, or voluntary or involuntary dissolution, liquidation or
winding up of the Company shall be effected, then in any such case, the Company
shall cause to be mailed by certified mail to the Holder, at least fifteen days
prior the date specified in (x) or (y) below, as the case may be, a notice
containing a brief description of the proposed action and stating the date on
which (x) a record is to be taken for the purpose of such dividend,
distribution or rights, or (y) such reclassification, reorganization,
consolidation, merger, conveyance, lease, dissolution, liquidation or winding
up
<PAGE>   11
is to take place and the date, if any is to be fixed, as of which the holders
of Common Stock or other securities shall receive cash or other property
deliverable upon such reclassification, reorganization, consolidation, merger,
conveyance, dissolution, liquidation or winding up.

                 (i)      RECLASSIFICATION, REORGANIZATION OR MERGER.  In case
of any reclassification, capital reorganization or other change of outstanding
shares of Common Stock of the Company, or in case of any consolidation or
merger of the Company with or into another corporation (other than a merger
with a subsidiary in which merger the Company is the continuing corporation and
which does not result in any reclassification, capital reorganization or other
change of outstanding shares of Common Stock of the class issuable upon
exercise of this Warrant) or in case of any sale, lease or conveyance to
another corporation of the property of the Company as an entirety, the Company
shall, as a condition precedent to such transaction, cause effective provisions
to be made so that the Holder shall have the right thereafter by exercising
this Warrant at any time prior to the expiration of the Warrant, to purchase
the kind and amount of shares of stock and other securities and property
receivable upon such reclassification, capital reorganization and other change,
consolidation, merger, sale or conveyance by a holder of the number of shares
of Common Stock which might have been purchased upon exercise of this Warrant
immediately prior to such reclassification, change, consolidation, merger, sale
or conveyance.  Any such provision shall include provision for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Warrant.  The foregoing provisions of this Section (i)
shall similarly apply to successive reclassifications, capital reorganizations
and changes of shares of Common Stock and to successive consolidations,
mergers, sales or conveyances.  In the event that in connection with any such
capital reorganization or reclassification, consolidation, merger, sale or
conveyance, additional shares of Common Stock shall be issued in exchange,
conversion, substitution or payment, in whole or in part, for a security of the
Company other than Common Stock, any such issue shall be treated as an issue of
Common Stock covered by the provisions of Subsection (1) of Section (f) hereof.

                 (j)      REGISTRATION UNDER THE SECURITIES ACT OF 1933.

                          (1)     The Company shall advise the Holder of this
                 Warrant or of the Warrant Shares or any then holder of
                 Warrants or Warrant Shares (such persons being collectively
                 referred to herein as "holders") by written notice at least
                 four weeks prior to the filing of any new registration
                 statement or post-effective amendment thereto under the
                 Securities Act of 1933 (the "Act") covering securities of the
                 Company which the Company proposes to sell solely for cash
                 (other than a registration statement on Form S-4, S-8 or other
                 form which does not include substantially the same information
                 as would be required in a form for the general registration of
                 securities) and will for a period of six years from the date
                 hereof upon the request of any such holder, include in any
                 such registration statement such information as may be
                 required to permit a public offering of the Warrant Shares.
                 The Company shall supply prospectuses and other documents as
                 the Holder may request in order to facilitate the public sale
                 or other disposition of the Warrant Shares, qualify the
                 Warrant Shares for sale in such states as any such holder
                 designates and do any and all other acts and things which may
                 be
<PAGE>   12
                 necessary or desirable to enable such Holders to consummate
                 the public sale or other disposition of the Warrant Shares,
                 and furnish indemnification in the manner as set forth in
                 Subsection (3)(C) of this Section (j).  Such holders shall
                 furnish information and indemnification as set forth in
                 Subsection (3)(C) of this Section (j), except that the maximum
                 amount which may be recovered from the Holder shall be limited
                 to the amount of proceeds received by the Holder from the sale
                 of the Warrant Shares.

                          (2)     If any majority holder (as defined in
                 Subsection (4) of this Section (j) below) shall give notice to
                 the Company at any time during the five year period commencing
                 on the date hereof to the effect that such holder contemplates
                 (i) the transfer of all or any part of his or its Warrant
                 Shares, or (ii) the exercise and/or conversion of all or any
                 part of his or its Warrants and the transfer of all or any
                 part of the Warrant Shares under such circumstances that a
                 public offering (within the meaning of the Act) of Warrant
                 Shares will be involved, and desires to register under the
                 Act, the Warrant Shares, then the Company shall, within two
                 weeks after receipt of such notice, file a registration
                 statement pursuant to the Act, to the end that the Warrant
                 Shares may be sold under the Act as promptly as practicable
                 thereafter and the Company will use its best efforts to cause
                 such registration to become effective and continue to be
                 effective (current) (including the taking of such steps as are
                 necessary to obtain the removal of any stop order) until the
                 holder has advised that all of the  Warrant Shares have been
                 sold; provided that such holder shall furnish the Company with
                 appropriate information (relating to the intentions of such
                 holders) in connection therewith as the Company shall
                 reasonably request in writing.  In the event the registration
                 statement is not declared effective under the Act prior to
                 October 23, 2000, the Company shall extend the expiration date
                 of the Warrants to a date not less than 90 days after the
                 effective date of such registration statement.  The holder
                 may, at its option, request the registration of the Warrant
                 Shares in a registration statement made by the Company as
                 contemplated by Subsection (1) of this Section (j) or in
                 connection with a request made pursuant to Subsection (2) of
                 this Section (j) prior to the acquisition of the Warrant
                 Shares upon exercise of the Warrants and even though the
                 holder has not given notice of exercise of the Warrants.  If
                 the Company determines to include securities to be sold by it
                 in any registration statement originally requested pursuant to
                 this Subsection (2) of this Section (j), such registration
                 shall instead be deemed to have been a registration under
                 Subsection (1) of this Section (j) and not under Subsection
                 (2) of this Subsection (j).  The holder may thereafter at its
                 option, exercise the Warrants at any time or from time to time
                 subsequent to the effectiveness under the Act of the
                 registration statement in which the Warrant Shares were
                 included.

                          (3)     The following provision of this Section (j)
                 shall also be applicable:

                                  (A)      Within ten days after receiving any
                          such notice pursuant to Subsection (2) of this
                          Section (j), the Company shall give notice to the
                          other holders of Warrants and Warrant Shares,
                          advising that the Company
<PAGE>   13
                          is proceeding with such registration statement and
                          offering to include therein Warrant Shares of such
                          other holders, provided that they shall furnish the
                          Company with such appropriate information (relating
                          to the intentions of such holders) in connection
                          therewith as the Company shall reasonably request in
                          writing. Following the effective date of such
                          registration, the Company shall upon the request of
                          any owner of Warrants and/or Warrant Shares forthwith
                          supply such a number of prospectuses meeting the
                          requirements of the Act, as shall be requested by
                          such owner to permit such holder to make a public
                          offering of all Warrant Shares from time to time
                          offered or sold to such holder, provided that such
                          holder shall from time to time furnish the Company
                          with such appropriate information (relating to the
                          intentions of such holder) in connection therewith as
                          the Company shall request in writing.  The Company
                          shall also use its best efforts to qualify the
                          Warrant Shares for sale in such states as such
                          majority holder shall designate.

                                  (B)      The Company shall bear the entire
                          cost and expense of any registration of securities
                          initiated by it under Subsection (1) of this Section
                          (j) notwithstanding that Warrant Shares subject to
                          this Warrant may be included in any such
                          registration.  The Company shall also comply with one
                          request for registration made by the majority holder
                          pursuant to Subsection (2) of this Section (j) at its
                          own expense and without charge to any holder of any
                          Warrants and/or Warrant Shares; and the Company shall
                          comply with one additional request made by the
                          majority holder pursuant to Subsection (2) of this
                          Section (j) (and not deemed to be pursuant to
                          Subsection (1) of this Section (j)) at the sole
                          expense of such majority holder.  Any holder whose
                          Warrant Shares are included in any such registration
                          statement pursuant to this Section (j) shall,
                          however, bear the fees of his own counsel and any
                          registration fees, transfer taxes or underwriting
                          discounts or commissions applicable to the Warrant
                          Shares sold by him pursuant thereto.

                                  (C)      The Company shall indemnify and hold
                          harmless each such holder and each underwriter,
                          within the meaning of the Act, who may purchase from
                          or sell for any such holder any Warrants and/or
                          Warrant Shares from and against any and all losses,
                          claims, damages and liabilities caused by any untrue
                          statement or alleged untrue statement of a material
                          fact contained in the Registration Statement or any
                          post-effective amendment thereto or any registration
                          statement under the Act or any prospectus included
                          therein required to be filed or furnished by reason
                          of this Section (j) or caused by any omission or
                          alleged omission to state therein a material fact
                          required to be stated therein or necessary to make
                          the statements therein not misleading, except insofar
                          as such losses, claims, damages or liabilities are
                          caused by any such untrue statement or alleged untrue
                          statement or omission or alleged omission based upon
                          information furnished or required to be furnished in
                          writing to the
<PAGE>   14
                          Company by such holder or underwriter expressly for
                          use therein, which indemnification shall include each
                          person, if any, who controls any such underwriter
                          within the meaning of such Act provided, however,
                          that the Company will not be liable in any such case
                          to the extent that any such loss, claim, damage or
                          liability arises out of or is based upon an untrue
                          statement or alleged untrue statement or omission or
                          alleged omission made in said registration statement,
                          said preliminary prospectus, said final prospectus or
                          said amendment or supplement in reliance upon and in
                          conformity with written information furnished by such
                          Holder or any other Holder, specifically for use in
                          the preparation thereof.

                                  (D)      Neither the giving of any notice by
                          any such majority holder nor the making of any
                          request for prospectuses shall impose any upon such
                          majority holder or owner making such request any
                          obligation to sell any Warrants and/or Warrant
                          Shares, or exercise any Warrants.

                          (4)     The term "majority holder" as used in this
                 Section (j) shall include any owner or combination of owners
                 of Warrants or Warrant Shares in any combination if the
                 holdings of the aggregate amount of:

                                  (i)      the Warrants held by him or among
                          them, plus

                                  (ii)     the Warrants which he or they would
                          be holding if the Warrants for the Warrant Shares
                          owned by him or among them had not been exercised,

                 would constitute a majority of the Warrants originally issued.
<PAGE>   15
                 The Company's agreements with respect to Warrants or Warrant
Shares in this Section (j) shall continue in effect regardless of the exercise
and surrender of this Warrant.

         THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
         OR THE SECURITIES LAWS OF ANY STATE, PURSUANT TO ONE OR MORE
         EXEMPTIONS THEREFROM.  THIS WARRANT MAY NOT BE SOLD, TRANSFERRED,

                 Void after 5:00 p.m. New York Time, on October 23, 2000
                 Warrant to Purchase ____________ Shares of Common Stock


                        WARRANT TO PURCHASE COMMON STOCK
                                       OF
                               XPLOR CORPORATION

                 This is to Certify That, FOR VALUE RECEIVED,
________________________________ , or assigns ("Holder"), is entitled to
purchase, subject to the provisions of this Warrant, from Xplor Corporation, a
Delaware corporation ("Company"), __________________ fully paid, validly issued
and nonassessable shares of Common Stock, par value $0.01 per share, of the
Company ("Common Stock") at a price of $3.00 per share at any time or from time
to time during the period from the date hereof to October 23, 2000 but not
later than 5:00 p.m. New York City Time, on October 23, 2000.  The number of
shares of Common Stock to be received upon the exercise of this Warrant and the
price to be paid fro each share of Common Stock may be adjusted from time to
time as hereinafter set forth.  The shares of Common Stock deliverable upon
such exercise, and as adjusted from time to time, are hereinafter sometimes
referred to as "Warrant Shares" and the exercise price of a share of Common
Stock in effect at any time and as adjusted from time to time is hereinafter
sometimes referred to as the "Exercise Price".

                 (a)      EXERCISE OF WARRANT.  This Warrant may be exercised
in whole or in part at any time or from time to time on or after the date
hereof and until October 23, 2000 (the "Exercise Period"); provided, however,
that if either such day is a day on which banking institutions in the State of
New York are authorized by law to close, then this Warrant may be exercised, in
whole or in part, on the next succeeding day which shall not be such a day.
This Warrant may be exercised by presentation and surrender hereof to the
Company at its principal office, or at the office of its stock transfer agent,
if any, with the Purchase Form annexed hereto duly executed and accompanied by
payment of the Exercise Price for the number of Warrant Shares specified in
such form.  As soon as practicable after each such exercise of this Warrant,
but not later than seven (7) days from the date of such exercise, the Company
shall issue and deliver to the Holder a certificate or certificates for the
Warrant Shares issuable upon such exercise, registered in the name of the
Holder or its designee.  If this Warrant should be exercised in part only, the
Company shall, upon surrender of this Warrant for cancellation, execute and
deliver a new Warrant evidencing the rights of the Holder thereof to purchase
the balance of the Warrant Shares purchasable thereunder.  Upon receipt by the
Company of this Warrant at its office, or by the stock transfer agent of the
Company at its office, in proper form for exercise, the Holder
<PAGE>   2
shall be deemed to be the holder of record of the shares of Common Stock
issuable upon such exercise, notwithstanding that the stock transfer books of
the Company shall then be closed or that certificates representing such shares
of Common Stock shall not then be physically delivered to the Holder.

                 (b)      TRANSFER RESTRICTION LEGEND.      Each certificate
representing Warrant Shares initially issued upon exercise of this Warrant,
unless at the time of exercise such Warrant Shares are registered under the
Securities Act, shall bear the following legend (and any additional legend
required by any securities exchange on which the Warrant Shares may at the time
be listed) on the fact thereof:

         "The securities represented hereby have not been registered under the
         Securities Act of 1933, and the transfer of such securities is subject
         to the restrictions set forth in the Warrant pursuant to which such
         securities have been issued, a copy of which is available for
         inspection at the principal executive offices of Xplor Corporation,
         and no transfer of such securities shall be valid or effective unless
         and until the terms and conditions of said Warrant shall have been
         complied with."

Any certificate issued at any time upon transfer of, or in exchange for or
replacement of, any certificate bearing such legend (except a new certificate
issued upon completion of a public distribution of the securities represented
thereby pursuant to a registration under the Securities Act) shall also bear
such legend unless, in the opinion of counsel for the Company, or such other
counsel as shall be acceptable to the Company, in each case addressed and
delivered to the Company, the securities represented thereby need no longer be
subject to the restrictions contained in this Warrant.  The provisions of this
Warrant shall be binding upon all subsequent holders of certificates bearing
the above legend and shall also be applicable to all subsequent holders of this
Warrant.

                 (c)      RESTRICTIONS ON TRANSFER.

                 (1)      General Restrictions.    Notwithstanding any
provisions contained in this Warrant to the contrary, this Warrant and the
related Warrant Shares bearing the legend as provided in Section (b) of this
Warrant shall not be transferable except upon the conditions specified in this
Section (c), which conditions are intended, among other things, to insure
compliance with the provisions of the Securities Act in respect of the transfer
of this Warrant or of such Warrant Shares.  The registered holder of this
Warrant agrees that it will neither (i) transfer this Warrant prior to delivery
to the Company of the opinion of counsel referred to in, and to the effect
described in, Section (c)(2), or until registration hereof under the Securities
Act, nor (ii) transfer such Warrant Shares prior to delivery to the Company of
the opinion of counsel referred to in, and to the effect described in, Section
(c)(2), or until registration of such Warrant Shares under the Securities Act
has become effective.

                 (2)      Statement of Intention to Transfer: Opinion of
Counsel.   The registered holder of this Warrant, by its acceptance hereof,
agrees that prior to any transfer
<PAGE>   3
of this Warrant or any transfer of the related Warrant Shares bearing the
legend as provided in Section (b) of this Warrant, said holder will deliver to
the Company a statement setting forth either said holder's intention with
respect to the disposition of this Warrant or of any Warrant Shares (whichever
is involved in such transfer), in either such case, together with a signed copy
of the opinion of said holder's counsel as shall be acceptable to the Company,
as to the necessity or non-necessity for registration under the Securities Act
in connection with such transfer.  Each such opinion shall either be addressed
to the Company or state that the Company may rely thereon.  The following
provisions shall then apply:

         i.               If, in the opinion of said holder's counsel, the
                 proposed transfer of this Warrant or the proposed transfer of
                 such Warrant Shares may be effected without registration under
                 the Securities Act of this Warrant or such Warrant Shares, as
                 the case may be, then the registered holder of this Warrant
                 shall be entitled to transfer this Warrant or to transfer such
                 Warrant Shares in accordance with the statement of intention
                 delivered by said holder to the Company.

         ii.              If, in the opinion of said counsel, either the
                 proposed transfer of this Warrant or such Warrant Shares may
                 not be effected without registration under the Securities Act
                 of this Warrant or such Warrant Shares, as the case may be,
                 the registered holder of this Warrant shall not be entitled to
                 transfer this Warrant or such Warrant Shares, as the case may
                 be, until such registration is effective.

                 (d)      RESERVATION OF SHARES.   The Company shall at all
times reserve for issuance and/or delivery upon exercise of this Warrant such
number of shares of its Common Stock as shall be required for issuance and
delivery upon exercise of the Warrants.

                 (e)      FRACTIONAL SHARES.       No fractional shares or
script representing fractional shares shall be issued upon the exercise of this
Warrant.  With respect to any fraction of a share called for upon any exercise
hereof, the Company shall pay to the Holder an amount in cash equal to such
fraction multiplied by the current market value of a share, determined as
follows:

                          (1)     If the Common Stock is listed on a national
                 securities exchange or admitted to unlisted trading privileges
                 on such exchange or listed for trading on the Nasdaq National
                 Market, the current market value shall be the last reported
                 sale price of the Common Stock on such exchange or market on
                 the last business day prior to the date of exercise of this
                 Warrant or if no such sale is made on such day, the average
                 closing bid and asked prices for such day on such exchange or
                 market; or
<PAGE>   4
                          (2)     If the Common Stock is not so listed or
                 admitted to unlisted trading privileges, but is traded on the
                 Nasdaq SmallCap Market, the current Market Value shall be the
                 average of the closing bid and asked prices for such day on
                 such market and if the Common Stock is not so traded, the
                 current market value shall be the mean of the last reported
                 bid and asked prices reported by the National Quotation
                 Bureau, Inc. on the last business day prior to the date of the
                 exercise of this Warrant; or

                          (3)     If the Common Stock is not so listed or
                 admitted to unlisted trading privileges and bid and asked
                 prices are not so reported, the current market value shall be
                 an amount, not less than book value thereof as at the end of
                 the most recent fiscal year of the Company ending prior to the
                 date of the exercise of the Warrant, determined in such
                 reasonable manner as may be prescribed by the Board of
                 Directors of the Company.

                 (f)      EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT.
This Warrant is exchangeable, without expense, at the option of the Holder,
upon presentation and surrender hereof to the Company or at the office of its
stock transfer agent, if any, for other warrants of different denominations
entitling the holder thereof to purchase in the aggregate the same number of
shares of Common Stock purchasable hereunder.  This Warrant is not transferable
other than by will or pursuant to the laws of descent and distribution and
except as provided under Subsection (c) hereof.  Upon surrender of this Warrant
to the Company at its principal office or at the office of its stock transfer
agent, if any, with the Assignment Form annexed hereto duly executed and funds
sufficient to pay any transfer tax, the Company shall, without charge, execute
and deliver a new Warrant in the name of the assignee named in such instrument
of assignment and this Warrant shall promptly be canceled.  This Warrant may be
divided or combined with other warrants which carry the same rights upon
presentation hereof at the principal office of the Company or at the office of
its stock transfer agent, if any, together with a written notice specifying the
names and denominations in which new Warrants are to be issued and signed by
the Holder hereof.  The term "Warrant" as used herein includes any Warrants
into which this Warrant may be divided or exchanged.  Upon receipt by the
Company of evidence satisfactory to it of the loss, theft, destruction or
mutilation of this Warrant, and (in the case of loss, theft or destruction) of
reasonably satisfactory indemnification, and upon surrender and cancellation of
this Warrant, if mutilated, the Company will execute and deliver a new Warrant
of like tenor and date.  Any such new Warrant executed and delivered shall
constitute an additional contractual obligation on the part of the Company,
whether or not this Warrant so lost, stolen, destroyed, or mutilated shall be
at any time enforceable by anyone.

                 (g)      RIGHTS OF THE HOLDER.   The Holder shall not, by
virtue hereof, be entitled to any rights of a shareholder in the Company,
either at law or equity, and the rights of the Holder are limited to those
expressed int eh Warrant and are not enforceable against the Company except to
the extent set forth herein.

                 (h)      ANTI-DILUTION PROVISIONS.         The Exercise Price
in effect at any time and the number and kind of securities purchasable upon
the exercise of the Warrants shall be subject to adjustment from time to time
upon the happening of certain events as follows:

                          (1)     In case the Company shall (i) declare a
                 dividend or make a distribution on its outstanding shares of
                 Common Stock in shares of Common Stock, (ii) subdivide or
                 reclassify its outstanding shares of Common Stock into a
                 greater number of shares, or (iii) combine or reclassify its
                 outstanding shares of Common Stock into a smaller number of
                 shares, the Exercise Price in effect at the time of the record
                 date for such dividend or distribution or of the effective
                 date of such subdivision, combination or reclassification
                 shall be adjusted so that it shall equal the price determined
                 by multiplying the Exercise Price by a fraction, the
                 denominator of which shall be the number of shares of Common
                 Stock outstanding after giving effect to such action, and the
                 numerator of which shall be the number of shares of Common
                 Stock outstanding immediately prior to such action.  Such
                 adjustment shall be made immediately prior to such action.
                 Such adjustment shall be made successively whenever any event
                 listed above shall occur.

                          (2)     Whenever the Exercise Price payable upon
                 exercise of each Warrant is adjusted pursuant to Subsection
                 (1) above, the number of Shares purchasable upon exercise of
                 this Warrant shall simultaneously be adjusted by multiplying
                 the number of Shares initially issuable upon exercise of this
                 Warrant by the Exercise Price in effect on the date hereof and
                 dividing the product so obtained by the Exercise Price, as
                 adjusted.

                          (3)     In the event that at any time, as a result of
                 an adjustment made pursuant to Subsection (1) above, the
                 Holder of this Warrant thereafter shall become entitled to
                 receive any shares of the Company, other than Common Stock,
                 thereafter the number of such other shares so receivable upon
                 exercise of this Warrant shall be subject to adjustment from
                 time to time in a manner and on terms as nearly equivalent as
                 practicable to the provisions with respect to the Common Stock
                 contained in Subsection (1) above.

                 (i)      REGISTRATION UNDER THE SECURITIES ACT OF 1933.

                          (1) The Company shall advise the Holder of this
                 Warrant of the Warrant Shares or any then holder of Warrants
                 or Warrant Shares (such person being collectively referred to
                 herein as "holder") by written notice at least two weeks prior
                 to the filing of any registration statement or post-effective
                 amendment thereto under the Securities
<PAGE>   6
                 Act of 1933 covering securities of the Company and will for
                 the period until October 23, 2001, upon the request of any
                 such holder, include in any such registration statement such
                 information as may be required to permit a public offering of
                 the Warrant Shares.  In connection with its filing of any
                 registration statement or post-effective amendment thereto,
                 the Company shall supply prospectuses and other documents as
                 the Holder may request in order to facilitate the public sale
                 or other disposition of the Warrant Shares, qualify the
                 Warrant Share for sale in such states as any such holder
                 designates and do any and all other acts and things which may
                 be necessary or desirable to enable such Holders to consummate
                 the public sale or other disposition of the Warrant Shares.

                          (2) If any registration pursuant to Subsection 1 of
                 this Section (i) shall be underwritten in whole or in part,
                 the Company may require that the Warrant Shares requested for
                 inclusion pursuant to Subsection 1 of this Section (i) be
                 included int eh underwriting on the same terms and conditions
                 as the securities otherwise being sold through the
                 underwriters.  In the event that in the good faith judgment of
                 the managing underwriter of such public offering the inclusion
                 of all of the Warrant Shares covered by a request for
                 registration would reduce the number of shares to be offered
                 by the Company or interfere with the successful marketing of
                 the shares of stock offered by the Company, the number of
                 Warrant Shares otherwise to be included in the underwritten
                 public offering may be reduced pro rata (by number of shares)
                 among the holders thereof requesting such registration or
                 excluded in their entirety if so required by the underwriter.
                 To the extent only a portion of the Warrant Shares is included
                 in the underwritten public offering, those Warrant Shares
                 which are thus excluded from the underwritten public offering
                 shall be withheld from the market by the holders thereof for a
                 period, not to exceed 120 days, which the managing underwriter
                 reasonably determines is necessary in order to effect the
                 underwritten public offering.

                 The obligation of the Company under Subsection 2 of this
                 Section (i) shall be limited to two registration statements.

                          (3)     The Company shall bear the entire cost and 
                 expense of any registration of securities initiated by it 
                 under Subsection (1) of this Section (i) notwithstanding that 
                 Warrant Shares may be included in any such registration.  Any
                 holder whose Warrant Shares are included in any such 
                 registration statement pursuant to this Section (i) shall, 
                 however, bear the fees of his own counsel and any 
                 registration fees, transfer taxes or underwriting discounts 
                 or commissions applicable to the Warrant Shares sold by him 
                 pursuant thereto.

                                    Recitals

         A.  Each of the Shareholders represents that he or she is the owner of
the number of shares of capital stock of The New Venus
<PAGE>   2
Exploration, Inc., called the "Company", set forth opposite his or her name
above.

         B.  In order to provide for the smooth and efficient operation of the
Company, to prevent conflicts, and to avoid deadlocks, the Shareholders deem it
to be in the best interest of the Company and all of its shareholders that this
agreement be executed.

         For these reasons, the Shareholders, in consideration of their mutual
promises, agree with each other and with the Trustee, and the Trustee agrees
with the Shareholders, as follows:

         Section One. Transfer of Stock to Trustee.  Each Shareholder will
deposit the number of shares of capital stock set forth opposite his or her
name above and the certificates representing those shares, together with
sufficient instruments executed for their transfer to the Trustee, with the
Trustee, and will receive in exchange trust certificates.  On the making of
that deposit, all shares represented by the stock certificates so deposited
will be transferred on the books of the Company to the name of the Trustee, who
is authorized and empowered to cause such transfers to be made, and also to
cause any further transfers to be made that may become necessary due to a
change in the identity of any trustee or trustees as provided here.

         Section Two. Trustee's Control Over Stock.  During the period this
agreement remains in force, the Trustee will possess legal title to the shares
deposited and will be entitled to exercise all rights whatsoever, including the
right to vote in person or by proxy, in respect of any and all deposited
shares.  Each holder of a trust certificate issued by the Trustee will be
entitled to receive payments equal to any and all dividends collected by the
Trustee with respect to shares of stock deposited by the holder of  that trust
certificate.

         Section Three. Voting Trust Certificate.  Upon deposit by any
Shareholder of a certificate or certificates for shares of stock under this
agreement, accompanied by instruments of transfer, the Trustee will deliver or
cause to be delivered to the Shareholder, a voting trust certificate or
certificates for the same number of shares of stock as may be represented by
the certificate or certificates deposited.

                                                        ---------------------
                                                        E. L. Ames, Jr.,
                                                        Trustee

         Section Four. Additional Stock.  After this agreement has taken
effect, the Trustee may, from time to time, receive any additional fully paid
shares of the capital stock of the Company on the same terms and conditions as
are set forth in this agreement. In respect of all shares so received, the
Trustee will issue and deliver certificates substantially in the form set out
above, entitling the holder to all the rights specified above.

         Section Five. Dividends.  All dividends that may accrue on the
deposited stock must be distributed pro rata among the holders of the voting
trust certificates in the proportion they are entitled.

         Section Six. Sale of Stock and Certificates by Shareholders.  During
the period from the date of this agreement until the second anniversary of the
first day the Company's shares are freely tradeable on a recognized stock
exchange or market pursuant to the Company's initial public offering, but not
later than July 1, 2000, the Shareholders agree, and the Trustee accepts this
trust only on the condition, that the Shareholders will not sell their
equitable interests in their respective shares in a manner that would remove
those shares from the effect of this agreement.  However, the voting trust
certificates may be sold, pledged or mortgaged, but every assignee or
transferee of a voting trust certificate issued under this agreement will, by
the acceptance of such certificate,





                                       3

become a party to this agreement, with the same effect as though an original
subscriber to the agreement, and the Trustee will continue to have all rights
granted to it pursuant to this agreement.  Irrespective of the foregoing, the
Shareholders acknowledge that all the shares of the Company are presently
restricted shares and are not freely tradeable or transferable.  Only when the
Trustee has been supplied with such evidence as he may require, in his sole
discretion, that a transfer of any of the shares or certificates may be made
under, and in accordance with, the rules and laws of the all applicable
governments and agencies, including, without limitation, the U.S. federal and
state securities laws and regulations, will any request for a new such voting
certificate be considered.  If that evidence has not been supplied and accepted
by the Trustee for any reason, no Shareholder will request a new certificate,
nor will the Trustee be under any duty to deliver same.

         Section Seven. Rights of Trustee.  During the period this agreement
remains in effect, the Trustee will possess and will be entitled to exercise,
in person or by proxy, all rights and powers of absolute ownership in respect
of all the stock of the Company deposited with him, including the right to vote
on, to take part in, and consent to, any corporate or shareholders' election or
action of any kind whatsoever, and to receive dividends and distributions on
the stock.  The Trustee's right to vote will include the right to vote for the
election of directors and in favor of, or in opposition to, any resolution or
proposed action of any character whatsoever that may require the consent of
shareholders.

         Section Eight. Successor Trustee.         In the event that E. L.
Ames, Jr., is no longer capable of serving as Trustee or no longer desires to
serve as Trustee, John Y. Ames, E. L. Ames III and Elizabeth Ames Jones, shall
be requested to serve as Co-Trustees, and if they accept, they shall serve as
dependent co-trustees; i.e., actions by the Trustee under this Agreement will
require each of their signatures to be effective.

         Section Nine. Termination of Voting Trust.  On the earlier of (i) the
second anniversary of the first day that the Company's shares were freely
tradeable on a recognized stock exchange or market pursuant to the Company's
initial public offering, but not later than July 1, 2000, or (ii) the second
anniversary of the closing (if it occurs) of the transaction currently being
considered by the Company with Xplor Corporation and two affiliates of Lomak
Petroleum, Inc.  with regard to a business combination of those entities, the
Trustee will distribute the stock of the Company held by it to the holders of
the voting trust certificates in proportion to their respective holdings on
surrender of their certificates to the Trustee, and this agreement will
terminate.  Notwithstanding the foregoing to the contrary, the Trustee is
hereby given the right to terminate, at its sole discretion, this





                                       4

agreement at any time prior to those dates, in which case it shall distribute
the stock as specified above.

         Section Ten. Sale or Purchase of Shares or Certificates by Trustee.
Nothing contained in this agreement will deprive the Trustee, in its individual
capacity, of the privilege to be enjoyed by all other depositors of selling or
otherwise disposing of voting trust certificates as they see fit, or of
purchasing additional certificates, or of purchasing additional stock and
selling it.

         Section Eleven. Compensation of Trustee.  The Trustee (or Co-Trustees)
will not be entitled to any compensation for its services as such.

         Section Twelve. Resignation of Trustee.  Any trustee may resign at any
time by delivering to the Shareholders its written resignation, to take effect
thirty (30) days after the delivery of the resignation.  The term "Trustee" as
used in this agreement applies to any properly appointed successor Trustee or
Co-Trustee.

         Section Thirteen. Trustee's Liability for Negligence.  In voting the
shares of stock held by it or doing any other act with respect to the control
or management of the Company as holder of the deposited stock, the Trustee will
exercise its best judgment in the interest of the Company, to the end that its
affairs be properly managed.  No trustee will be liable for any error of
judgment or mistake of law or fact or for any error or omission whatsoever save
only its willful misconduct or gross negligence.

         Section Fourteen. Amendment of Voting Trust.  This agreement may be
amended or terminated at any time by an instrument in writing executed and
acknowledged by the owners and holders of trust certificates representing over
50% of the shares of stock deposited under this agreement.

         Section Fifteen. Acceptance of Trust by Trustee.  The Trustee accepts
this trust subject to all of its terms and conditions and agrees that it will
exercise its powers and perform its duties as set forth in this agreement.

amount of all Advances at any time outstanding shall not exceed the lesser of
(i) the Borrowing Base in effect from time to time; or (ii) the amount of the
Commitment.  Subject to the foregoing limitations and other terms of this
Agreement, Borrower may borrow, repay and reborrow under the Commitment.  The
Obligation to repay the Advances made to Borrower pursuant to the Commitment
shall be evidenced by Borrower's Note in the form of Exhibit 2.1 hereto,
payable to the order of Bank.

         Within the limits of this Section 2.1, Borrower may borrow, repay and
reborrow hereunder, according to the terms hereof, each Advance being evidenced

(the "Request for Advance") signed by an executive officer of Borrower in the

                 2.2      Borrowing Base.

                 (a)      On or before February 15 and August 15 of each year
Borrower shall furnish to Bank (i) a report in form and substance satisfactory
to Bank, of a petroleum engineer satisfactory to Bank, which report shall be
dated as of January 1, as prepared by an independent third party petroleum
engineering firm acceptable to Bank, and July 1, as prepared by Borrower, of
such year and shall set forth the proven oil and gas reserves of Borrower, as
of such date; (ii) any updated production history of the proven oil and gas
reserves of Borrower; (iii) the discounted net present value (at a rate
reasonably acceptable to Bank); (iv) the net general overhead and
administrative expenses and the lease operating expenses attributable to the
Oil and Gas Properties of Borrower for the prior twelve month period; and (v)
such other information as to the operations of Borrower as Bank shall
reasonably request.  Together with each of the reports to be furnished pursuant
to this Section 2.2(a) Borrower shall furnish to Bank such additional data and
information concerning pricing, quantities or volume of production from or
attributable to the Oil and Gas Properties with respect thereto as Bank may
reasonably request.

                 (b)      After receipt of all of the information required by
Section 2.2(a), Bank may redetermine the amount of the Borrowing Base in
accordance with the customary practices of Bank for oil and gas loans to be
effective as of April 1 and October 1 of such year.  In connection with the
initial Redetermination of the Borrowing Base as set forth herein, Borrower
agrees to pay to Bank an Engineering Fee in the amount of $2,500.  Thereafter,
upon delivery to Bank of the information required by 2.2(a), Borrower shall pay
to Bank an Engineering Fee in the amount of $2,500.  Until the next
determination of the amount of the Borrowing Base by Bank, the amount of the
Borrowing Base as of the Closing Date shall be deemed to be $2,500,000 upon
Bank obtaining duly perfected Bank Liens on the Oil and Gas Properties of
Borrower set forth on Schedule 2.2(b)(i) hereto and thereafter increased to
$5,250,000 upon Bank obtaining duly perfected Bank Liens on the Oil and Gas
Properties of Borrower set forth on Schedule 2.2(b)(ii) hereto. Borrower shall
have forty-five (45) days from the execution and delivery by Borrower of
Mortgages in favor of Bank on the Oil and Gas Properties described in the
foregoing Schedules to confirm, to the reasonable satisfaction of Bank, either
by receipt of legal opinions or other method acceptable to Bank that the
Mortgages have been duly recorded and constitute perfected first Bank Liens on
the Oil and Gas Properties of Borrower described therein. Thereafter, until
each new determination of Borrowing Base is made by Bank, the amount of the
Borrowing Base shall be deemed to be the Borrowing Base last deemed or
calculated, as the case may be.  In addition to the foregoing, Bank or Borrower
may initiate a redetermination of the Borrowing Base at any other time as it so
elects, provided, however, that Borrower may initiate only two (2) such
unscheduled redeterminations during any consecutive twelve (12) month period by
specifying in writing to Bank the date on which Borrower will furnish the
information required by Section 2.2(a) and the date on which it desires such
redetermination to occur.  Bank shall have at least forty-five (45) days after
the delivery of the information required by Section 2.2(a) to make any
unscheduled redetermination of the Borrowing Base requested by Borrower.  Bank
may, at any time and at its expense, initiate an unscheduled redetermination of
the Borrowing Base by specifying in writing to Borrower the date by which
Borrower is to furnish the information required by Section 2.2(a) (excluding
the information required by Section 2.2(a)(i)) and the projected date on which
such redetermination is to occur.  Failure of Borrower to timely furnish such
information required by Section 2.2(a) shall not preclude Bank's right to
redetermine the Borrowing Base based on information previously furnished to
Bank.  Bank shall promptly notify in writing Borrower of the new Borrowing
Base.  Any redetermination of the Borrowing Base shall not be effective until
written notice is sent to Borrower.

<PAGE>   19
                 (c)      In the event the aggregate unpaid principal amount of
all Advances, shall, at any time, be in excess of the amount of the Borrowing
Base in effect at such time, then Borrower shall, within thirty (30) days of
such event, at the option of Borrower, either (i) subject to the Bank Lien, by
instruments satisfactory in form and substance to Bank, provide additional
collateral with value in amounts satisfactory to Bank in accordance with the
customary practices of Bank for oil and gas loans, in order to increase the
Borrowing Base by an amount at least equal to such excess; or (ii) prepay the
outstanding principal of the Note in an aggregate amount at least equal to such
excess; or (iii) subject to the approval of Bank, pay to Bank up to one hundred
percent (100%) of the Net Proceeds from Production until the aggregate unpaid
principal amount of all Advances, is equal to or less than the Borrowing Base
then in effect.

                 2.3      Repayment.  Accrued interest on the Advances shall be
due and payable monthly commencing on June 30th and continuing on the last day
of each day of each month thereafter until all Advances are paid in full.  All
principal and unpaid interest thereon shall be due and payable on the
Commitment Termination Date.  All payments received on the Advances shall be
applied first to accrued interest and then to principal.

                 2.4      Interest.

                 (a)      Each Prime Rate Advance shall bear interest on the
unpaid principal amount thereof until payment in full at the Prime Rate, but in
no event to exceed the Highest Lawful Rate.  Any change in the interest rate
accruing on an Advance resulting from a change in the Prime Rate shall become
effective as of the opening of business on the day on which such change in the
Prime Rate shall occur.  Each LIBOR Advance shall bear interest on the unpaid
principal amount thereof until payment in full at the Effective LIBOR Rate, but
in no event to exceed the Highest Lawful Rate.

                 (b)      Notwithstanding the foregoing, if at any time the
Applicable Rate exceeds the Highest Lawful Rate, any subsequent reductions in
the Applicable Rate shall not reduce the rate of interest hereunder below the
Highest Lawful Rate until the total amount of interest accrued approximately
equals (but does not exceed) the amount of interest which would have accrued if
the Applicable Rate had at all times been in effect.  In the event that at
maturity (whether stated or by acceleration) or at final payment of the Note,
the total amount of interest paid or accrued on the Note is less than the
amount of interest which would have accrued if the Applicable Rate had at all
times been in effect with respect thereto, then at such time Borrower shall pay
to Bank an amount equal to the difference between (i) the lesser of the amount
of interest which would have accrued if the Applicable Rate had at all times
been in effect and the amount of interest which would have accrued if the
Highest Lawful Rate had at all times been in effect; and (ii) the amount of
interest actually accrued on the Note.

                 (c)      Notwithstanding the foregoing, all past-due principal
of and interest on the Note shall bear interest at a rate per annum from day to
day equal to the lesser of (i) the Highest Lawful Rate in effect from day to
day; or (ii) the Prime Rate plus 5% (the "Default Rate"), from maturity
(whether stated or by acceleration) until paid.

                 (d)      Interest shall be calculated (i) (A) for Prime Rate
Advances, on the basis of a 360-day year; and (B) for LIBOR Advances, on the
basis of a year of 360 days; and (ii) for the actual number of days elapsed,
including the first day, but excluding the last day.  Interest shall be





                                       14
<PAGE>   20
due and payable on each Interest Payment Date and on the Commitment Termination
Date on the Note.

                 2.5      Voluntary Prepayments.   Borrower shall be entitled
to prepay the Prime Rate Advances from time to time and at any time, in whole
or in part, without penalty; provided that unless Borrower and Bank otherwise
agree in writing (a) all accrued interest and any and all fees and other sums
then due and payable to Bank under the Loan Documents shall be paid; (b) a
prepayment shall be applied to installments of principal of the Advances in
inverse order of maturity; (c) any partial prepayment must be at least $100,000
and must be an integral multiple of $25,000; and (d) and Borrower may prepay
any Prime Rate Advance in connection with the Credit Sweep Service provided by
Bank to Borrower as described on Exhibit 2.5 hereof. Borrower must have given
Bank one (1) Business Day prior written notice of the intention to prepay any
part of the Prime Rate Advances; and a LIBOR Advance may only be paid on the
last day of the Interest Period therefor.

                 2.6      Manner and Application of Payments and Prepayments.
Each payment or prepayment of interest or principal on the Advances must be
paid at Bank's principal office in Houston, Texas, in funds which are or will
be available for immediate use by Bank by 12:00 noon Central Time on the day
such payment or prepayment is due or made.  In any case, where a payment of
principal of or interest on the Advances is due on a day which is not a
Business Day, Borrower shall be entitled to delay such payment until the next
succeeding Business Day, but interest shall continue to accrue at the rate then
effective under the Note until the payment is in fact made.

                 2.7      Mandatory Prepayments.  Subject to the provisions of
Section 2.2(c), if, at any time, the sum of the outstanding principal balance
under the Note exceeds the Borrowing Base, or if at any time the Borrower has
knowledge that the sum of the outstanding principal balance under the Note
exceeds the Borrowing Base, then Borrower shall forthwith prepay the amount of
such excess for application towards reduction of the outstanding principal
balance of the Note.  Such prepayment shall be with no premium or penalty, and
shall be made together with the payment of accrued interest on the amount
prepaid.

                 2.8      Capital Adequacy.  If either (i) the introduction of
or any change in or in the interpretation of any Law or regulation; or (ii)
compliance by Bank with any guideline or request from any central bank or other
Tribunal (whether or not having the force of Law) affects or would affect the
amount of capital required or expected to be maintained by Bank or any
corporation controlling Bank and Bank determines that the amount of such
capital is increased by or based upon the existence of Bank's obligations and
commitments hereunder and other obligations and commitments of this type, then,
upon demand by Bank, Borrower shall immediately pay to Bank, from time to time
as specified by Bank, additional amounts sufficient to compensate Bank in the
light of such circumstances, to the extent that Bank reasonably determines that
such increase in capital to be allocable to the existence of Bank's obligations
and commitments hereunder.  A certificate as to such amounts submitted to
Borrower by Bank, shall, in the absence of manifest error, be conclusive and
binding for all purposes.

                 2.9      Facility Fee.  At Closing, Borrower shall pay to Bank
a Facility Fee equal to three-eighths percent (3/8%) of the increased Borrowing
Base.  Thereafter, Borrower shall pay to Bank a Facility Fee equal to three-
eighths percent (3/8%) of any increase in the Borrowing Base as redetermined
from time to time.  Notwithstanding the foregoing, if the Borrowing Base is
reduced





                                       15
<PAGE>   21
and thereafter subsequently increased, no Facility Fee will be due until the
Borrowing Base exceeds the largest amount previously granted to Borrower and in
such event the Facility Fee will only be applicable to the increase over such
highest amount.  For example, if the Borrowing Base is reduced to $4,000,000
and subsequently increased to $5,000,000, no Facility Fee is due.  If the
Borrowing Base is increased to $6,000,000, a Facility Fee is due based on the
difference between the highest Borrowing Base, i.e., $5,250,000 and $6,000,000.

                 2.10     Commitment Fee.  From the date hereof until the
Commitment Termination Date, Borrower shall pay to Bank a commitment fee, as it
accrues on the tenth (10th) day of each July, October, January, and April equal
to three-eighths percent (3/8%) per annum (calculated on the basis of actual
days elapsed, but computed as if each calendar year consisted of 360 days) on
the daily average difference, during the preceding calendar quarter or portion
thereof preceding such payment date, between Borrowing Base in effect for such
calendar quarter and the principal amount outstanding under the Note.

                 2.11     Use of Proceeds.  Borrower may use the proceeds of
the Advances to refinance Debt in favor of Stratum under the Stratum Documents;
finance future acquisitions, working capital and other general corporate
purposes.

                 2.12     Special Provisions Regarding LIBOR Advances.

                 (a)      Illegality.  Notwithstanding any other provisions of
this Agreement or the Note, if at any time Bank shall determine in good faith
that any change in Applicable Law or in the interpretation thereof makes it
unlawful for Bank to make or continue to maintain any LIBOR Advance, Bank shall
promptly give notice thereof to Borrower and the obligation to make, continue
or effect by conversion any LIBOR Advance under this Agreement shall be
suspended until Bank shall notify Borrower that the circumstances causing such
suspension no longer exist.  Borrower may request that the principal amount of
any affected LIBOR Advance begin to accrue interest as a Prime Rate Advance,
subject to all of the terms and conditions of this Agreement.

                 (b)      Unavailability of Deposits or Inability to Ascertain
LIBOR.  Notwithstanding any other provision of this Agreement or the Note to
the contrary, if prior to the commencement of any Interest Period Bank shall
determine (i) that deposits in the amount of any LIBOR Advance are not
available to Bank or (ii) by reason of circumstances affecting the London
interbank Eurodollar market, adequate and reasonable means do not exist for
ascertaining the LIBOR, then Bank shall promptly give notice thereof to
Borrower and the obligation of Bank to make, continue or effect by conversion
any such LIBOR Advance in such amount and for such Interest Period shall
terminate until deposits in such amount and for the Interest Period selected by
Borrower shall again be readily available to Bank and adequate and reasonable
means exist for ascertaining the LIBOR.  Upon the giving of such notice,
Borrower may elect to either (i) pay or prepay, as the case may be, such
affected LIBOR Advance or (ii) convert such affected LIBOR Advance to another
type of Advance available hereunder, subject to all of the terms and conditions
of this Agreement.

                 (c)      Funding Indemnity.  In the event Bank shall incur any
actual loss, cost, expense or premium (including, without limitation, any loss
of profit and any loss, cost, expense or premium incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by Bank to fund
or maintain any LIBOR Advance or the relending or reinvesting of such deposits
or amounts paid or prepaid to Bank) as a result of: (i) any payment of a LIBOR
Advance on a date





                                       16
<PAGE>   22
other than the last day of the then applicable Interest Period; (ii) any
failure by Borrower to borrow, continue, or effect by conversion any LIBOR
Advance on the date specified in a notice given pursuant to Section 2.1; or
(iii) the occurrence of any Event of Default; then, upon the demand of Bank,
Borrower shall pay to Bank, for the benefit of Bank, such amount as will
reimburse Bank for such loss, cost or expense.  If Bank makes a claim for
reimbursement on behalf of Bank, it shall provide to Borrower a certificate
setting forth the amount of such loss, cost or expense in reasonable detail and
such certificate shall be presumed correct as to the amount thereof in the
absence of manifest error.

                 (d)      Discretion of Bank as to Manner of Funding.
Notwithstanding any provision of this Agreement to the contrary, Bank shall be
entitled to fund and maintain its funding of all or any part of the LIBOR
Advances in any manner Bank sees fit, it being understood however, that for the
purposes of this Agreement all determinations hereunder shall be made as if
Bank had actually funded and maintained each LIBOR Advance during each Interest
Period for such Advance through the purchase of deposits having maturity
corresponding to such Interest Period and bearing an interest rate equal to the
LIBOR for such Interest Period.

                 (e)      LIBOR Reserve Costs.  Borrower agrees to pay Bank
additional interest on the outstanding principal amount of each LIBOR Advance
from the date such LIBOR Advance is made until such LIBOR Advance is paid in
full or converted to another type of Advance at an interest rate per annum
equal, at all times during such Interest Period, to (i) the rate obtained by
dividing (A) Bank's LIBOR for such Interest Period by (B) a percentage
(expressed as a decimal) equal to 100% minus the Reserve Percentage of Bank for
such Interest Period minus (ii) Bank's LIBOR for such Interest Period, but in
no event to exceed the Highest Lawful Rate.  Bank shall notify Borrower of the
interest due pursuant to this Section 2.13, which notice shall be presumed
correct in the absence of manifest error.

                 (f)      Taxes and Increased Costs.  With respect to any LIBOR
Advance, if Bank shall determine in good faith that any change in Applicable
Law (including, without limitation, Regulation D) or any new Applicable Law, or
any interpretation of any of the foregoing by any Tribunal charged with the
administration thereof or any central bank or other fiscal, monetary or other
authority having jurisdiction over Bank (whether or not having the force of
Law) shall:

                          (i)     impose, modify or deem applicable any
         assessment rate, reserve, special deposit or similar requirements
         against letters of credit issued by, or assets held by, or deposits in
         or for the account of, or loans by, or any other acquisition of funds
         or disbursements by Bank;

                          (ii)    subject Bank, any LIBOR Advance or their
         respective Note to any tax, duty, charge, stamp tax, fee, deduction or
         withholding in respect of this Agreement, any LIBOR Advance or the
         Note, except such taxes as may be measured by the overall net income
         of Bank and imposed by the jurisdiction, or any political subdivision
         or taxing authority thereof, in which Bank's principal executive
         office is located;

                          (iii)   change the basis of taxation of payments of
         principal and interest due from Borrower to Bank hereunder or under
         their respective Note (other than by a change in basis of taxation of
         the net income of Bank); or





                                       17
<PAGE>   23
                          (iv)    impose on Bank any penalty with respect to
         the foregoing or any other condition regarding this Agreement, its
         disbursement, any fixed rate Advance or their respective Note;

and Bank shall determine that the result of any of the foregoing is to increase
the cost (whether by incurring a cost or adding to a cost) to Bank for making
or maintaining any LIBOR Advance or to reduce the amount of principal or
interest received by Bank, then Borrower shall pay to Bank, from time to time
as specified by Bank, such additional amounts as Bank shall determine are
sufficient to compensate and indemnify Bank for such increased cost or reduced
amount.  Bank shall promptly give Borrower notice of any condition described in
this section that gives Bank a right to compensation under this section.  If
Bank makes such a claim for compensation, it shall provide to Borrower a
certificate setting forth, in reasonable detail, such increased cost or reduced
amount as a result of any event mentioned herein and such certificate shall be
presumed correct.

                             ARTICLE 3.  COLLATERAL

                 3.1      Bank Lien in Collateral.  The full and complete
payment and performance of the Obligation shall be secured under the Security
Instruments by first and prior Bank Liens in, to and on all of Borrower's
respective Rights, titles and interests in and to (but none of Borrower's
obligations with respect to) the following items and types of property (the
"Collateral"), all as more particularly set forth and described in the Security
Instruments:

                 (a)      All present and future Rights, titles and interests
that Borrower may now have or hereafter acquire in and to the Oil and Gas
Properties, including, but not limited to, oil and gas and/or oil, gas and
mineral leases and interests, royalty and overriding royalty interests,
production payment and net profits interests, mineral fee interests, and Rights
therein, including, without limitation, all reversionary or carried interests
relating to the foregoing, together with all present and future Rights, titles
and interests in and to all present and future unitization, communitization and
pooling agreements (and all properties covered and units created thereby),
whether arising by contract or operation of Law, which now or hereafter include
all or any part of the foregoing and together with all lands now or hereafter
subject to any of the foregoing, and all tenements, hereditaments,
appurtenances, and properties in anywise appertaining, belonging, affixed or
incidental to any of the foregoing.

                 (b)      All present and future Hydrocarbon Interests now or
hereafter accruing to or produced from mineral interests described in (a)
preceding and to which Borrower now or hereafter may be entitled as a result of
ownership thereof.

                 (c)      Whether now owned or hereafter acquired, all present
and future Rights, titles and interests of Borrower, (including without
limitation, the Rights to receive payments due thereunder) in and to any and
all gas sales contracts, oil, gas or other condensates or other products sales
contracts now or hereafter existing in connection with the Collateral described
hereinabove.

                 3.2      Security Instruments.  The Bank Liens in the
Collateral shall be further evidenced and governed by the Security Instruments.

                 3.3      Proceeds Account.  The Security Instruments contain
an assignment by Borrower to Bank of all production of Borrower's Hydrocarbons
and all proceeds attributable thereto





                                       18
<PAGE>   24
properly allocable to the Oil and Gas Properties of Borrower.  Borrower and
Bank hereby agree to open an account with Bank into which all such proceeds
from the production of Hydrocarbons shall be deposited  (the "Proceeds
Account").  Borrower hereby grants to Bank, subject to the prior assignment in
favor of Bank of Borrower's production and its proceeds, a security interest in
that portion of the Proceeds Account attributable to the Hydrocarbon Interests.
Notwithstanding the foregoing, Borrower may, until Bank shall give notice to
the contrary, have access to all such proceeds in the Proceeds Account.  Upon
the occurrence of an Event of Default, Bank may apply any and all balances
attributable to Borrower in the Proceeds Account to the Obligations.

               ARTICLE 4.  CERTAIN REPRESENTATIONS AND WARRANTIES

                 Borrower represents and warrants to Bank that:

                 4.1      Corporate Existence and Business.  Borrower is (a) a
corporation duly organized, validly existing and in good standing under the
Laws of its jurisdiction of incorporation; (b) is duly qualified to transact
business as a foreign corporation in each other jurisdiction where the nature
or extent of its business and properties require the same; and (c) possesses
all requisite authority, power, licenses, permits and franchises to conduct its
business as presently conducted.

                 4.2      Subsidiaries.  Borrower has no subsidiaries other
than the Subsidiaries set forth on Schedule 4.2.  Each Subsidiary (a) is a
corporation duly organized, validly existing and in good standing under the
Laws of its jurisdiction of incorporation; (b) is duly qualified to transact
business as a foreign corporation in each jurisdiction where the nature or
extent of its business and properties require the same; and (c) possesses all
requisite authority, power, licenses, permits and franchises to conduct its
business as presently conducted.  Except as set forth on Schedule 4.2, no
Subsidiary has used or transacted business under any other corporate name or
trade name in the five year period preceding the date hereof.

                 4.3      Power and Authorization; Enforceability.  Borrower
and each Subsidiary have full power, authority and legal right to execute,
deliver and perform the Loan Documents, and to borrow under this Agreement on
the terms and conditions hereof, and to grant the Bank Liens and to take such
action as may be necessary to complete the transactions contemplated by the
Loan Documents, and Borrower and each Subsidiary have taken all necessary
corporate and legal action to authorize the borrowing on the terms and
conditions of this Agreement and the grant of the Bank Liens and to authorize
the execution, delivery and performance of the Loan Documents on the terms and
conditions hereof and thereof.  Each of the Loan Documents has been duly
authorized, executed and delivered by Borrower and each Subsidiary and
constitutes a legal, valid and binding obligation of the party executing same,
enforceable against such party  in accordance with its terms.

                 4.4      Consents.  No consent of any other Person and no
consent, license, permit, approval or authorization of, exemption by, or
registration or declaration with, any Tribunal is required in connection with
the execution, delivery, performance, validity or enforceability of any of the
Loan Documents.

                 4.5      Financial Statements.  The Current Financials were
prepared in accordance with GAAP and fairly present the consolidated financial
condition and the results of operations of Borrower and its Subsidiaries as of,
and for the fiscal year ended on, the date thereof.  There were no material
liabilities, direct or indirect, fixed or contingent, of Borrower or any
Subsidiary as of the





                                       19
<PAGE>   25
date or dates of the Current Financials which are not reflected therein or in
the notes thereto.  There has been no material adverse change in the financial
condition of Borrower or any Subsidiary from that shown in the Current
Financials between such date or dates and the date hereof, nor has Borrower or
any Subsidiary incurred any material liability, direct or indirect, fixed or
contingent, other than in the ordinary course of business.

                 4.6      Tax Returns.  Borrower and its Subsidiaries have
filed all United States tax returns and all state and foreign tax returns
required to be filed by them and have paid, or made provisions for the payment
of, all Taxes which have become due pursuant to said returns or pursuant to any
assessments received by Borrower or any Subsidiary except such Taxes, if any,
as are being contested in good faith and as to which adequate reserves have
been provided in accordance with GAAP, and such returns properly reflect the
United States income tax, foreign tax and/or state taxes of Borrower or any
Subsidiary for the periods covered thereby.

                 4.7      Title to Properties; Liens.  Borrower has good and
defensible title to its respective material (individually or in the aggregate)
Oil and Gas Properties, free and clear of all Liens except Permitted Liens.  On
the date of this Agreement, after giving full effect to the Permitted Liens,
Borrower owns the net interests in production attributable to the wells and
units evaluated in the Initial Reserve Report or the most recent Reserve Report
furnished to Bank pursuant to Section 6.27 and the ownership of such Oil and
Gas Properties shall not in any material respect obligate Borrower to bear the
costs and expenses relating to the maintenance, development and operations of
each such Property in any amount in excess of the working interest of each Oil
and Gas Property set forth in the Initial Reserve Report or the most recent
Reserve Report furnished to Bank pursuant to Section 6.28.   All information
contained in the Initial Reserve Report or the most recent Reserve Report
provided to Bank (whichever is most recent) is true and correct in all material
respects.

                 4.8      First Lien.  Upon filing of the Mortgages with the
Clerk of the County or Parish where the property thereby covered is located and
financing statements with the Secretary of States of Texas and other
appropriate Tribunal where the Mortgages are filed, the Security Instruments
will constitute legal, valid and continuing perfected first liens on the
Collateral as security for the Obligation, free and clear of all other Liens,
except for Permitted Liens.

                 4.9      Compliance with Laws and Documents.  Neither Borrower
nor any Subsidiary is now, nor will the execution, delivery, or the performance
of and compliance with the terms of the Loan Documents cause Borrower or any
Subsidiary to be, in violation of (a) any Laws now in effect; (b) the terms of
any agreement, contract, document, or instrument to which Borrower or any
Subsidiary is a party or by which it or any of its assets is bound; or (c)
Borrower's or any Subsidiary's Articles or Certificate of Incorporation or
Bylaws.  Borrower has not violated any requirement of any Tribunal or failed to
obtain any license, permit, franchise or other governmental authorization
necessary for the ownership and operation of the Oil and Gas Properties or the
conduct of its business.  The Oil and Gas Properties (and properties unitized
therewith) have been maintained, operated and developed in a good and worker
like manner and in conformity with all applicable Laws and all rules,
regulations and orders of all duly constituted Tribunals having jurisdiction
and in conformity with the provisions of all leases, subleases or other
contracts comprising a part of the Hydrocarbon Interests and other contracts
and agreements forming a part of the Oil and Gas Properties; specifically in
this connection, (i) after the Closing Date, no Oil and Gas Property is subject
to having allowable production reduced below the full and regular allowable





                                       20
<PAGE>   26
(including the maximum permissible tolerance) because of any overproduction
(whether or not the same was permissible at the time) prior to the Closing
Date; and (ii) none of the wells comprising a part of the Oil and Gas
Properties (or properties unitized therewith) are deviated from the vertical
more than the maximum permitted by applicable Laws and regulations, rules and
orders of any Tribunal having appropriate jurisdiction, and such wells are, in
fact, bottomed under and are producing from, and the wellbores are wholly
within, the Oil and Gas Properties (or in the case of wells located on
properties unitized therewith, such unitized properties).

                 4.10     Litigation.  There is no action, suit or proceeding
pending or, to the knowledge of Borrower threatened, against Borrower or any
Subsidiary before any court, governmental department, administrative agency or
instrumentality which, if such action, suit or proceeding were adversely
determined, would materially adversely affect the financial position or the
results of operations of Borrower or any Subsidiary or its business or the
ability of Borrower or any Subsidiary to perform their respective obligations
under the Loan Documents.

                 4.11     Use of Proceeds; Margin Securities.  Neither Borrower
nor any Subsidiary is engaged principally, or as one of its important
activities, in the business of extending credit for the purpose of purchasing
or carrying "Margin Stock" (within the meaning of Regulations G, T, U, or X)
and no part of the proceeds of any extension of credit under this Agreement
will be used to purchase or carry any such Margin Stock or extend credit to
others for the purpose of purchasing or carrying Margin Stock.  Neither
Borrower nor any Person acting on its behalf has taken any action that might
cause the transactions contemplated by this Agreement or the Note to violate
Regulations G, T, U, or X or to violate the Securities Exchange Act of 1934, as
amended.

                 4.12     Employee Benefit Plans.  Neither Borrower nor any
Subsidiary has (a) incurred an accumulated funding deficiency in an amount
sufficient to have a Material Adverse Effect under any employee benefit plan
(as defined in the IRC and ERISA); (b) incurred material liability to PBGC in
connection with any benefit plan; (c) withdrawn in whole or in part from
participation in a multiemployer pension plan (as defined in ERISA); or (d)
committed, permitted or suffered any "prohibited transaction" or "reportable
event" (as defined in ERISA).

                 4.13     Purpose of Advances.  The proceeds of the Advances
are not and will not be used directly or indirectly (a) for the purpose of
purchasing or carrying, or for the purpose of extending credit to others for
the purpose of purchasing or carrying, any "margin stock" as that term is
defined in Regulation U; or (b) for any purpose which violates Regulation X.

                 4.14     No Default.  No Event of Default or Potential 
Default has occurred.

                 4.15     Government Regulation.  Neither Borrower, any
Affiliate of Borrower nor any  subsidiary is subject to regulation under the
Public Utility Holding Company Act of 1935, the Federal Power Act, the
Investment Company Act of 1940, the Interstate Commerce Act (as any of the
preceding acts have been amended) or any other Law which regulates the
incurring by any Person of Debt, including, without limitation, Laws relating
to common or contract carriers or the sale of electricity, gas, steam, water or
other public utility service.

                 4.16     Burdensome Provisions.  Except for the obligations of
Borrower under the Stratum Documents, neither Borrower nor any Subsidiary is a
party to any agreement or instrument containing any burdensome or uncustomary
provisions, or subject to any charter or other corporate





                                       21
<PAGE>   27
restrictions or to any judgment, order, writ, injunction, decree, award, rule
or regulation, which will or could cause a Material Adverse Effect.

                 4.17     Relationship with Bank.  No Person having "control"
of Borrower or any Subsidiary is an "executive officer," "director" or "person
who directly or indirectly or in concert with one or more persons, owns,
controls or has the power to vote more than 10% of any class of voting
securities" (as such terms are defined in the Financial Institutions Regulatory
and Interest Rate Control Act of 1978 and the regulations thereunder, as
amended) of Bank or any bank with which Bank maintains correspondent accounts.

                 4.18     Principal Office.  The principal place of business,
the chief executive office and the place at which the books and records of
Borrower and each Subsidiary are kept is 1250 Northeast Loop 410, Suite 1000,
San Antonio, Texas 78209.

                 4.19     Full Disclosure.  Neither the Loan Documents nor any
other agreement, document, certificate or statement furnished to Bank by or on
behalf of Borrower or any Subsidiary in connection with the transactions
contemplated in any of the Loan Documents contains any untrue statement of
material fact or omits to state a material fact necessary in order to make
statements contained herein or therein not misleading.  There are no
significant material facts or conditions relating to the making of Advances,
any of the Collateral and/or the financial condition and business of Borrower
or any Subsidiary which could, collectively or individually, cause a Material
Adverse Effect, and which have not been fully disclosed, in writing, to Bank.
All writings heretofore or hereafter exhibited or delivered to Bank by or on
behalf of Borrower are and will be genuine and in all respects what they
purport to be.

                 4.20     Solvency.  After giving effect to the initial Advance
and the other transactions contemplated by the Loan Documents, Borrower will be
Solvent as of and on the Closing Date and on the date of each subsequent
Advance.

                 4.21     Environmental Laws.  To the best knowledge and belief
of Borrower, except as described on Schedule 4.21:

                 (a)      no Oil and Gas Property of Borrower is currently on
or has ever been on, or is adjacent to any property which is on or has ever
been on, any federal or state list of Superfund Sites;

                 (b)      no Hazardous Substances have been generated,
transported and/or disposed of by Borrower at a site which was, at the time of
such generation, transportation, and/or disposal, or has since become, a
Superfund Site;

                 (c)      except in accordance with applicable Law or the terms
of a valid permit, license, certificate, or approval of the relevant Tribunal,
no Release of Hazardous Substances by Borrower or from, affecting, or related
to any Oil and Gas Property of Borrower or adjacent to any Oil and Gas Property
of Borrower has occurred in concentrations or locations that require any
remedial action under Environmental Laws;

                 (d)      no Notice under any Environmental Laws has been
received by Borrower which could reasonably be expected to have a Material
Adverse Effect;





                                       22
<PAGE>   28
                 (e)      neither Borrower nor any Oil and Gas Property of
Borrower is subject to any remedial obligations with respect to any
Environmental Law; and

                 (f)      Borrower has taken prudent steps to ensure that its
Oil and Gas Properties are and will continue to be in compliance with all
Environmental Laws.

                 4.22     Gas Imbalances.  Except as set forth on Schedule
4.22, on a net basis there are no gas imbalances, take or pay or other
prepayments with respect to Borrower's Oil and Gas Properties which would
require Borrower or any Subsidiary to deliver Hydrocarbons produced from
Borrower's Oil and Gas Properties at some future time without then or
thereafter receiving full payment therefor.

                 4.23     Hedging Agreements.  Schedule 4.23 sets forth a true
and complete list of all Hedging Agreements (including commodity price swap
agreements, forward agreements or contracts of sale which provide for
prepayment for deferred shipment or delivery of oil, gas or other commodities)
of Borrower, the material terms thereof (including the type, term, effective
date, termination date and notional amounts or volumes), the net mark to market
value thereof, all credit support agreements relating thereto (including any
margin declared or supplied) and the counter party to each such agreement).

                 4.24     Stratum Documents.  The Stratum Documents are in full
force and effect; are the legal, valid and binding obligations of Venus
Development and are non recourse to Borrower or any other Person.

executive office or place where any of Borrower's or each Subsidiary's books
and records related to accounts are kept, or otherwise relocate any of the
other Collateral to another county, parish or state unless (i) Borrower or any
Subsidiary gives Bank thirty (30) days' prior written notice of such proposed
relocation (such notice to include, without limitation, the name of the county
or parish and state into which such relocation is to be made); and (ii) except
where the relocation is to a jurisdiction in which existing financing
statements or other required filings have previously been made to perfect the
Bank Liens in the Collateral, and Borrower or any Subsidiary execute and
deliver all such additional documents and perform all additional acts that
Bank, in its sole discretion, may request in order to continue or maintain the
existence and priority of the Bank Liens in such Collateral; and

                 (b)      Perform such acts and duly authorize, execute,

Subsidiary shall at all times maintain and keep, or cause to be maintained and
kept, in good repair, working order and condition all of its respective

replacements, betterments and improvements thereto, so that the business
carried on in connection therewith may be properly and advantageously conducted
at all times.

                 6.6      Insurance.  Borrower and each Subsidiary now
maintains, and Borrower and each Subsidiary shall continue to maintain, at its
expense, with financially sound and reputable insurers, insurance with respect
to its properties and business against such liabilities, casualties, risks and
contingencies and in such types and amounts as is customary in the case of
Persons engaged in the same or similar businesses and similarly situated.  In
the case of any fire, accident or other casualty causing loss or damage to any
properties of Borrower or any Subsidiary, at Borrower's or any Subsidiary's
discretion, the proceeds of such policies shall be used (i) to repair or
replace the damaged property; or (ii) to prepay the Obligation.

                 6.7      Taxes.  Borrower and each Subsidiary shall promptly

which reserves have been established in an amount acceptable to Bank and the
criteria for Permitted Liens have been satisfied.  Borrower and each Subsidiary
shall not, directly or indirectly, use any portion of the proceeds of any

                 6.8      Payment and Prepayment of Obligations.  Borrower and

                                       27
<PAGE>   33
of money as the same become due, except any such Debt or contractual
obligations being contested in good faith by appropriate legal proceedings, for
which a reserve for the payment thereof has been established in accordance with
GAAP, and with respect to which failure to promptly pay or renew and extend
does not result in the violation of any provision of any material agreement,
contract, document or instrument of Borrower or any Subsidiary that could cause
a Material Adverse Effect.  Furthermore, if an Event of Default shall have
occurred, Borrower or any Subsidiary shall not, directly or indirectly, make
any voluntary or involuntary prepayment on the principal of any Debt (other

for the performance of the obligations of the lessee or tenant under any lease
or sublease (including, without limitation, leases or subleases which should,
in accordance with GAAP, be capitalized for financial reporting purposes) of
property, other than leases or subleases which would not require Borrower or
any Subsidiary to make lease or sublease payments in excess of $250,000 in the
aggregate during any twelve (12) month period (provided, however, that the
foregoing limitations shall not apply to oil and gas leases entered into in the
ordinary course of business.)

                 6.11     Liens.  Borrower or any Subsidiary shall not,
directly or indirectly, create, incur, suffer or permit to be created or
incurred or to exist, any Lien upon any of its assets, except Permitted Liens.

transaction (including, but not limited to, the sale or exchange of property or

promptly pay all reasonable out-of-pocket costs, fees and expenses paid or
incurred by (a) Bank incident to any of the Loan Documents (including, without

Borrower and each such Subsidiary will promptly pay and discharge or cause to
be paid and discharged all delay rentals, royalties, expenses and Debt accruing

and will do all other things necessary to keep unimpaired Borrower's or any
such Subsidiary's Rights with respect thereto and prevent any forfeiture
thereof or a default thereunder, except to the extent a portion of such Oil and
Gas Properties has not been or is no longer capable of producing Hydrocarbons
in economically reasonable amounts.  Borrower and each such Subsidiary will
operate the Oil and Gas Properties owned by Borrower or any such Subsidiary or
cause such Oil and Gas Properties to be operated in a manner in accordance with
the practices of the industry and in compliance with all applicable contracts
and agreements and in compliance in all material respects with all requirements

Properties of Borrower or any  Subsidiary as of the immediately preceding six
months (and dated as of January 1 and July 1, respectively) and which shall,
together with any other information reasonably requested by Bank, set forth the
proven producing and proven non-producing oil and gas reserves attributable to

                 6.28     Title Information.

                 (a)      By February 15 of each year, Borrower and each
Subsidiary will deliver acquisition summaries, title opinions and due diligence
reports prepared in connection with the acquisition and the financing of the
acquisition of such property prepared for Borrower or any Subsidiary and such
additional title information in form and substance reasonably acceptable to
Bank as is requested so that Bank shall have received, together with the title
information previously received by Bank, satisfactory title information
covering Oil and Gas Properties representing eighty percent (80%) of the value
of such Oil and Gas Properties as set forth in the Reserve Report specified in
Section 6.27, as such value is set forth therein.

                 6.29     Sales and Leasebacks.  Neither Borrower nor any
Subsidiary will enter into any arrangement, directly or indirectly, with any

                 6.31     Stratum Documents.  Neither Borrower nor any

                                       32
<PAGE>   38

stayed within sixty (60) days of the filing thereof.

                 (g)      The discovery by Bank that any statement,

                 (a)      Declare the entire unpaid balance of the Obligation,
or any part thereof, immediately due and payable, whereupon it shall be due and
payable, without notice of any kind to Borrower or any Subsidiary; provided
that, upon the occurrence of an Event of Default under Section 7.1(c), the
entire Obligation shall automatically become immediately due and payable
without notice or other action of any kind whatsoever.

                 (b)      Terminate its commitment to lend hereunder.

                 (c)      Reduce any claim to judgment.

                 (d)      Take such steps as Bank may deem appropriate to
foreclose the Bank Liens and/or otherwise realize upon any and all of the
Rights Bank may have in and to the Collateral or any part thereof.

                 (e)      Exercise any and all other Rights afforded by the
Laws of the State of Texas, the United States of America or any other
jurisdiction, as Bank shall deem appropriate, or by any of the Loan Documents,
at Law, in equity or otherwise, including, but not limited to, the Rights to
bring suit or other proceedings before any Tribunal either for specific
performance of any covenant or condition contained in any of the Loan Documents
or in aid of the exercise of any Right granted to Bank in any of the Loan
Documents.





                                       33
<PAGE>   39
                 (f)      Exercise the Rights of offset and/or banker's Lien
against the interest of Borrower or any Subsidiary in and to every account and
other property which are in the possession of Bank to the extent of the full
amount of the Obligation.

                 7.3      Performance by Bank.  Should any material covenant,
duty or agreement of Borrower or any Subsidiary fail to be performed in
accordance with the terms of the Loan Documents, Bank may, at its option,
perform or attempt to perform, such covenant, duty or agreement on behalf of
Borrower and each Subsidiary.  In such event, Borrower and each Subsidiary
shall, at the request of Bank, promptly pay to Bank any reasonable amount
expended by Bank in such performance or attempted performance, together with
interest thereon at a rate per annum equal to the Default Rate in effect from
day to day, from the date of such expenditure by Bank until paid.
Notwithstanding the foregoing, it is expressly understood that Bank does not
assume and shall never have, except by express written consent of Bank, any
liability or responsibility for the performance of any covenant, duty or
agreement of Borrower and each Subsidiary under any Loan Document.

                 7.4      Bank Not in Control.  None of the covenants or other
provisions contained in this Agreement shall, or shall be deemed to, give Bank
the right or power to exercise control over the affairs and/or management of
Borrower or any Subsidiary, the power of Bank being limited to the right to
exercise the remedies provided in this Section 7.

                 7.5      Waivers.  The acceptance by Bank at any time and from
time to time of part payment on the Obligation shall not be deemed to be a
waiver of any Event of Default then existing.  No waiver by Bank of any Event
of Default shall be deemed to be a waiver of any other then-existing or
subsequent Events of Default.  No delay or omission by Bank in exercising any
Right under the Loan Documents shall impair such Right or be construed as a
waiver thereof or any acquiescence therein, nor shall any single or partial
exercise of any such Right preclude other or further exercise thereof, or the
exercise of any other Right under the Loan Documents or otherwise.

                 7.6      Cumulative Remedies.  All Rights available to Bank
under the Loan Documents shall be cumulative of and in addition to all other
Rights granted to Bank at law or in equity.

                 7.7      Expenditures by Bank.  Any sums spent by Bank
pursuant to the exercise of any Right provided herein shall become part of the
Obligation and shall bear interest at a rate per annum from day to day equal to
the Default Rate in effect from day to day, from the date spent until the date
repaid by Borrower or any Subsidiary.

                 7.8      Delegation of Duties and Rights.  Bank may exercise
any of its duties and/or exercise any of its Rights under the Loan Documents by
or through its respective officers, directors, employees, attorneys, agents or
other representatives.

                              ARTICLE 8.  GENERAL

                 8.1      Ratifications.  The terms and provisions as set forth
in this Second Amended and Restated Loan Agreement shall modify and supersede
all inconsistent terms and provisions set forth in the Loan Agreement and
except as expressly modified and superseded by this Second Amended and Restated
Loan Agreement, the terms of the Note and any and all other Loan Documents
executed in connection therewith or hereunto are hereby ratified and confirmed

continue in full force and effect.  Borrower and Bank agree that this Second
Amended and Restated Loan Agreement, the Note and the other Loan Documents are

                 8.2      Status of Claims.  Borrower hereby represents and

presently constitute or will constitute a basis for any claim or cause of
action against Bank, or any defense to the payment of any of the Obligations.
Borrower hereby releases, relinquishes and forever discharges Bank, its
successors, assigns, agents, officers, directors, employees and
representatives, of and from any and all claims, demands, actions and causes of
action of any and every kind or character, whether known or unknown, present or

actions or omissions of Bank, its successors, assigns, agents, officers,

                 8.3      Captions.  The headings, captions and arrangements
used in any of the Loan Documents are, unless specified otherwise, for

                                  Attention:  Barry Davis, Esq.

                 8.6      Governing Law.

                 (a)      THE LOAN DOCUMENTS ARE BEING EXECUTED AND DELIVERED
BY BORROWER AND BANK, AND ARE INTENDED TO BE PERFORMED, IN THE STATE OF TEXAS,
AND (EXCEPT AS SPECIFICALLY PROVIDED OTHERWISE IN ANY LOAN DOCUMENT OR TO THE
EXTENT THAT THE LAWS OF ANY OTHER JURISDICTION OTHERWISE REQUIRE) THE INTERNAL
LAWS OF THE STATE OF TEXAS AND OF THE UNITED STATES OF AMERICA SHALL GOVERN THE
RIGHTS AND DUTIES OF THE PARTIES AND THE VALIDITY, CONSTRUCTION, ENFORCEMENT,
AND INTERPRETATION OF THE LOAN DOCUMENTS.

                 (b)      THE PARTIES AGREE TO BE BOUND BY THE TERMS AND
PROVISIONS OF THE CURRENT ARBITRATION PROGRAM OF BANK, WHICH IS INCORPORATED BY
REFERENCE HEREIN AND IS ACKNOWLEDGED AS RECEIVED BY THE PARTIES, PURSUANT TO
WHICH ANY KNOWN DISPUTES SHALL BE RESOLVED BY MANDATORY BINDING ARBITRATION
UPON THE REQUEST OF EITHER PARTY.  THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN
CONNECTION WITH THIS AGREEMENT, AND WHETHER ARISING IN CONTRACT, TORT, EQUITY
OR OTHERWISE, SHALL BE RESOLVED ONLY BY THE TERMS AND PROVISIONS OF THE CURRENT
ARBITRATION PROGRAM OF BANK WHICH IS ATTACHED HERETO AS EXHIBIT 8.4(b) AND IS
INCORPORATED HEREIN BY REFERENCE, PURSUANT TO WHICH ANY AND ALL DISPUTES SHALL
BE RESOLVED BY MANDATORY BINDING ARBITRATION UPON THE REQUEST OF ANY PARTY.

                 8.7      Interest.  It is the intention of the Parties to
comply with applicable usury Laws; accordingly, it is agreed that
notwithstanding any provisions to the contrary in any Loan Document, in no
event shall any Loan Document permit the collection of interest in excess of
the maximum amount permitted by such Laws.  If any such excess of interest is
contracted for, charged or received under any Loan Document or if the maturity
of the Obligation is accelerated in whole or in part, or in the event that all
or part of the principal or interest of the Obligation shall be prepaid, so
that under any of such circumstances the amount of interest contracted for,
charged or received under any Loan Document on the amount of principal actually
outstanding from time to time under the Obligation shall exceed the maximum
amount of interest permitted by applicable usury Laws, then in any such event
(a) the provisions of this Section 8.5 shall govern and control; (b) no Person
now or hereafter liable for the payment of the Obligation shall be obligated to
pay the amount of such interest to the extent that it is in excess of the
maximum amount of interest permitted to be contracted for by, charged to or
received from the Person obligated thereon under the applicable usury Laws; (c)
any such excess which may have been collected shall be either applied as a
credit against the then unpaid principal amount on the Obligation or refunded
to the Person paying the same, at the holder's option; and (d) the effective
rate of interest shall be automatically reduced to the maximum lawful rate of
interest permitted to be contracted for by, charged to or received from the
Person obligated thereon under the applicable usury Laws as now or hereafter
construed by the courts having jurisdiction thereof.  To the extent the Laws of
the State of Texas are applicable for





                                       36
<PAGE>   42
purposes of determining the "Highest Lawful Rate," such term shall mean the
"indicated rate ceiling" from time to time in effect under Article 1.04, Title
79, Revised Civil Statutes of Texas, 1925, as amended, or, if permitted by
applicable Law and effective upon the giving of the notices required by such
Article 1.04 (or effective upon any other date otherwise specified by
applicable Law), the "monthly ceiling," the "quarterly ceiling," or "annualized
ceiling" from time to time in effect under such Article 1.04, whichever Bank
shall elect to substitute for the "indicated rate ceiling," and vice versa,
each such substitution to have the effect provided in such Article 1.04; and
Bank shall be entitled to make such election from time to time and one or more
times and, without notice to Borrower, to leave any such substitute rate in
effect for subsequent periods in accordance with subsection (h)(1) of such
Article 1.04.  Pursuant to Article 15.10(b) of Chapter 15, Subtitle 79, Revised
Civil Statutes of Texas, 1925, as amended, Borrower agrees that such Chapter 15
shall not govern or in any manner apply to the Obligation.

                 8.8      INDEMNIFICATION.  BORROWER HEREBY INDEMNIFIES BANK
AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES,
ATTORNEYS, AND AGENTS FROM, AND HOLDS EACH OF THEM HARMLESS AGAINST, ANY AND
ALL LOSSES, LIABILITIES, CLAIMS, DAMAGES, PENALTIES, JUDGMENTS, COSTS, AND
EXPENSES (INCLUDING ATTORNEYS' FEES) TO WHICH ANY OF THEM MAY BECOME SUBJECT
DIRECTLY OR INDIRECTLY ARISE FROM OR RELATE TO (A) THE NEGOTIATION, EXECUTION,
DELIVERY, PERFORMANCE, ADMINISTRATION, OR ENFORCEMENT OF ANY OF THE LOAN
DOCUMENTS, (B) ANY OF THE TRANSACTIONS CONTEMPLATED BY THE LOAN DOCUMENTS, (C)
ANY BREACH BY BORROWER OR ANY SUBSIDIARY OF ANY REPRESENTATION, WARRANTY,
COVENANT, OR OTHER AGREEMENT CONTAINED IN ANY OF THE LOAN DOCUMENTS, (D) THE
PRESENCE, RELEASE, THREATENED RELEASE, DISPOSAL, REMOVAL, OR CLEANUP OF ANY
HAZARDOUS SUBSTANCE LOCATED ON, ABOUT, WITHIN, OR AFFECTING ANY OF THE
PROPERTIES OR ASSETS OF BORROWER OR ANY SUBSIDIARY, OR (E) ANY INVESTIGATION,
LITIGATION, OR OTHER PROCEEDING, INCLUDING, WITHOUT LIMITATION, ANY THREATENED
INVESTIGATION, LITIGATION, OR OTHER PROCEEDING RELATING TO ANY OF THE FOREGOING
OR RELATING TO ANY OF THE INVENTORY PRODUCED OR SOLD BY BORROWER.  WITHOUT
LIMITING ANY PROVISION OF THIS AGREEMENT OR OF ANY OTHER LOAN DOCUMENT, IT IS
THE EXPRESS INTENTION OF THE PARTIES THERETO THAT EACH PERSON TO BE INDEMNIFIED
UNDER THIS SECTION SHALL BE INDEMNIFIED FROM AND HELD HARMLESS AGAINST ANY AND
ALL LOSSES, LIABILITIES, CLAIMS, DAMAGES, PENALTIES, JUDGMENTS, COSTS, AND
EXPENSES (INCLUDING ATTORNEY'S FEES) ARISING OUT OF OR RESULTING FROM THE SOLE
OR CONTRIBUTORY NEGLIGENCE OF THE PERSON TO BE INDEMNIFIED.  THE OBLIGATIONS OF
BORROWER UNDER THIS SECTION SHALL SURVIVE THE REPAYMENT OF THE OBLIGATIONS.

                 8.9      Severability.  If any provision of any of the Loan
Documents is held to be illegal, invalid or unenforceable under present or
future Laws effective during the term thereof, such provision shall be fully
severable; the appropriate Loan Document shall be construed and enforced as if
such illegal, invalid or unenforceable provision had never comprised a part
thereof; and the remaining provisions thereof shall remain in full force and
effect and shall not be affected by the illegal, invalid or unenforceable
provision or by its severance therefrom.  Furthermore, in lieu of





                                       37
<PAGE>   43
such illegal, invalid or unenforceable provision, there shall be added
automatically as a part of such Loan Document a provision as similar in terms
to such illegal, invalid or unenforceable provision as may be possible and be
legal, valid and enforceable.

                 8.10     Entire Agreement.  This instrument embodies the
entire agreement among the Parties with respect to the subject matter hereof,
supersedes and replaces all prior agreements and understandings, if any,
relating to the subject matter hereof, and may be amended only by an instrument
in writing executed jointly by authorized officers of Borrower and Bank, and
supplemented only by documents delivered or to be delivered in accordance with
the express terms hereof.

                         EXECUTIVE EMPLOYMENT AGREEMENT


         THIS EMPLOYMENT AGREEMENT ("Agreement") is made and entered as of the
1st day of June, 1996, by and between Venus Energy PLC, a company organized and
existing under the laws of the United Kingdom ("Company"), and E. L. Ames, Jr.,
an individual residing in San Antonio, Bexar County, Texas ("Employee").

         FOR AND IN CONSIDERATION of the mutual covenants herein contained and
the mutual benefits to be gained by the performance thereof and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto hereby agree as follows:

         1.      EMPLOYMENT.  Company hereby employs Employee and Employee
hereby accepts employment with Company on the terms and conditions herein set
forth.  In consideration of Employee's employment by Company, Employee agrees
to the terms, conditions and covenants of this Agreement.

         2.      TERM OF EMPLOYMENT.  Employment of Employee by Company shall
be for a term of three (3) years.

         3.      DUTIES AND RESPONSIBILITIES.  Employee shall serve as Chief
Executive Officer and, if elected by the Board of Directors of the Company,
Chairman of the Board of Directors of the Company.

                 3.01 EXTENT OF SERVICES.  Employee shall devote his efforts to
                 the advancement of the interests of the Company's business,
                 and he shall pursue no new business interests other than
                 passive investments, without the prior written approval of the
                 Company, which approval shall not be unreasonably withheld.
                 Employee shall minimize the interference any such activities
                 have on the conduct of the Company's business.

                 3.02 APPROVED OTHER BUSINESS INTERESTS.     The Company
                 understands and accepts the facts that the Employee owns
                 certain interests in oil and gas properties in his own right
                 and that the Employee may develop those interests and the
                 surrounding Areas of Mutual Interest without offering same to,
                 or in any way involving, the Company.  However, Employee
                 agrees that he will not acquire any new interests outside of
                 such Areas of Mutual Interests and that all new oil and gas
                 projects in which he is involved outside of such Areas of
                 Mutual Interest will be considered a Company project.

         4.      COMPENSATION AND BENEFITS.  The compensation and other
benefits listed below as payable to or accruing to Employee shall constitute
the full consideration to be paid to Employee for all services to be rendered
by Employee to Company and all other agreements of Employee hereunder.

                 4.01     BASE SALARY.  As compensation for all services of
                 whatever type rendered by Employee in the performance of his
                 duties under this Agreement and for all other agreements and
                 undertakings of Employee hereunder, Company shall pay to
                 Employee a base salary to be determined from time to time and
                 approved by the Board of Directors; however, in no event will
                 such salary be less than $_______ per year.  Such salary shall
                 be payable in equal regular installments in accordance with
                 Company's customary payroll payment policy.  It is
                 specifically understood and agreed that a portion of
                 Employee's annual base salary hereunder is attributable to
                 Employee's agreement, pursuant to Section 8 hereof, to
                 maintain the confidentiality of "Confidential Information" (as
                 herein defined), both during and after the term of this
                 Agreement, and that Employee's salary would be reduced
                 significantly if Employee did not agree to be bound by the
                 terms of Section 8.  It is further understood and agreed that
                 a portion of Employee's annual base salary is attributable to
                 Employee's agreement, pursuant to Section 9 hereof, not to
                 compete with Company either during or for a specified period
                 of time after the expiration or termination of this Agreement
                 and that Employee's annual salary would be reduced
                 significantly if Employee did not agree to be bound by the
                 terms of Section 9 hereof.  Employee agrees that he is being
                 fairly and reasonably compensated for the agreements
                 undertaken by Employee pursuant to Sections 8 and 9 hereof.

                 4.02     BENEFITS.  Employee shall be entitled to four weeks
                 paid vacation each year, the times for such vacation to be
                 mutually agreed upon by Employee and Company. Employee shall
                 be entitled to participate in the Company benefit programs
                 designed for Company employees with similar salaries, duties
                 and responsibilities.

                 4.03     EXPENSES.  Company shall pay or reimburse Employee
                 for all reasonable and necessary expenses actually incurred or
                 paid by Employee during the term of this Agreement in the
                 performance of Employee's services under this Agreement, upon
                 presentation of expense statements or vouchers or such other
                 supporting documents as Company may reasonably require.

<PAGE>   3
                 4.04     AUTOMOBILE.  The Company shall provide Employee an
                 automobile of class, style and age that are commensurate with
                 the position he holds and the needs of Employee in that
                 position.

         5.      REPRESENTATIONS, WARRANTIES AND AGREEMENTS.    Employee
represents, warrants and agrees that:  (i) Employee is not currently bound by
any employment agreement, restriction or other obligation of any kind that
would in any way materially interfere with or be inconsistent with the services
to be provided by Employee to Company hereunder; and (ii) Employee is free to
enter into this Agreement and the services and work product provided by
Employee to Company hereunder will be original works of Employee.

         6.      REGULATIONS AND POLICIES.  Employee shall, during the term of
this Agreement, comply with all Company regulations and policies, including,
without limitation, security regulations.

         7.      CONFIDENTIAL INFORMATION.  The term "Confidential
Information," as used herein, shall mean and include any and all documents,
knowledge, data or information (in whatever medium) known, communicated,
provided or made available to Employee, whether before or after the execution
of this Agreement, which are marked within a confidentiality legend by Company
or which Employee knows or reasonably should know constitute trade secrets of
Company or information belonging to third parties to whom Company may have an
obligation of confidentiality; provided, however, that Confidential Information
shall not include any information or materials which are or become generally
available to the public other than as a result of any breach of the provisions
of this Agreement or any other agreement between Employee and Company (or their
respective successors, assigns or affiliates).

         8.      CONFIDENTIALITY.  Employee acknowledges and agrees that in his
employment by Company he occupies a position of trust and confidence and that
during the term of his employment under this Agreement he will have access to
and will become familiar with Company's Confidential Information.  Employee
further acknowledges and agrees that the Confidential Information, including
any and all copies thereof, constitutes trade secrets of Company and is
confidential and proprietary information of Company.  Employee further
acknowledges and agrees that he has no right, title, interest or claim in or to
any of the Confidential Information or any copies thereof.  Employee agrees to
maintain the confidentiality of the Confidential Information and agrees that he
will not take, or permit to be taken, any action with respect to the
Confidential Information (or any portion thereof) which is inconsistent with
the confidential and proprietary nature of such information.  Without limiting
the generality of the foregoing, Employee agrees that he will not, directly or
indirectly, without the prior specific written consent of Company, except as
specifically required in the course of his employment,





                                       3

<PAGE>   4
         (i)     communicate, divulge, transmit or otherwise disclose any
                 Confidential Information to any person, firm, partnership,
                 corporation or other entity, or

         (ii)    use any Confidential Information in any manner except as
                 specifically required in connection with the performance of
                 services hereunder.

         Employee agrees to take any and all steps reasonably necessary to
protect the confidentiality of the Confidential Information.  Employee shall,
upon termination of this Agreement, immediately return to Company all
Confidential Information in Employee's control or possession, including,
without limitation, any and all copies thereof.  This Section shall survive the
expiration or termination of this Agreement for a period of three (3) years.

         9.      RESTRICTIVE COVENANT AND NONCOMPETITION.

         9.01   UPON TERMINATION.  As an independent covenant, Employee agrees
         that, for a period of three (3) years commencing upon the termination
         of this Agreement by expiration of its term or by the Company for
         cause, as provided in Section 12 of this Agreement, Employee will not,
         unless granted express written permission by the Board of Directors of
         Company, develop, work on or in any way advance, directly or
         indirectly, as an officer, director, stockholder, employee, advisor,
         consultant, partner, owner, agent, representative or in any other
         capacity, any competitor of Company or any other third party, any oil,
         gas and mineral exploration or production from the geographic areas,
         horizons, plays, formations or trends that the Company was studying to
         any significant extent during his employment; provided, however, that
         the foregoing shall not prohibit Employee from becoming a passive
         shareholder owning less than five percent (5%) of the shares of
         another corporation whose shares are publicly traded.

         9.02  COMPANY EMPLOYEES.  As an independent covenant, Employee agrees,
         during the term of this Agreement and, upon termination or expiration
         of this Agreement for any reason, for a period of eighteen (18) months
         thereafter, not to induce or attempt to influence any employee of
         Company to terminate his or her employment with Company.

         9.03  REASONABLENESS.  Employee acknowledges and agrees that the
         covenants and agreements set forth in this Section are made to protect
         the legitimate business interests of Company, including Company's
         interest in Confidential Information, and not to restrict his mobility
         or to prevent him from utilizing his skills.  Employee recognizes and
         acknowledges the necessarily national and international scope of the
         market served by Company and agrees that the restrictions set forth in
         this Section are reasonable.

<PAGE>   5
         9.04  SURVIVAL.  This Section 9 shall survive the expiration or
         termination of this Agreement.

         10.     PERFORMANCE BY EMPLOYEE.  Employee acknowledges and agrees
that the value of the Confidential Information and the success and long-term
viability of Company depends largely upon Employee's performance of his
obligations under Sections 8 and 9 of this Agreement.

         11.     INJUNCTIVE RELIEF.  Employee acknowledges and agrees that in
the event of any unauthorized use or disclosure of Confidential Information in
violation of the terms and conditions of Section 8 of this Agreement by
employee, or any breach of any of the terms and conditions of Section 9 of this
Agreement by Employee, Company will suffer irreparable injury not compensable
by money damages and, therefore, will not have an adequate remedy available at
law.  Accordingly, if Company institutes an action or proceeding to enforce the
provisions of Section 8 or 9 of this Agreement, Company shall be entitled to
obtain such injunctive relief or other equitable remedy from a court of
competent jurisdiction as may be necessary or appropriate to prevent or curtail
any such breach, threatened or actual.  The foregoing shall be in addition to
and without prejudice to such other rights as Company may have at law or in
equity.

         12.     TERMINATION.

         12.01  TERMINATION.  Employee's employment hereunder is terminable,
         with cause, at the will of either Company or Employee upon the giving
         of 30 days' prior written notice by either party; otherwise, it shall
         continue for the term of the Agreement as specified in Section 2, at
         which time it shall terminate.  If Employee's employment is terminated
         for cause by the Company before the expiration of the term of the
         Agreement, Company shall discontinue Employee's compensation as of the
         effective date of the termination of Employee's employment.  If
         Employee's employment is terminated for cause by the Employee, is
         terminated involuntarily, including, without limitation, termination
         resulting from the death or mental or physical disability of Employee,
         or is terminated without cause by the Company, Employee's regular
         compensation shall continue for the remainder of the term of the
         Agreement.  For purposes of this Agreement, "for cause" shall mean:

                 (a) Any willful or intentional act of either Employee or the
                 Company that has or will have the effect of injuring the
                 reputation or business relationships of the other party or its
                 affiliates;

                 (b) The non-terminating party's conviction of or entering a
                 plea of nolo contendere to a charge of felony or a misdemeanor
                 involving dishonesty or fraud;





                                       5
<PAGE>   6
                 (c) The non-terminating party's material breach of any of the
                 terms, covenants or conditions contained in this Agreement;
                 provided, however, that with respect to any breach that can be
                 effectively cured by some act of a party, termination of this
                 Agreement shall be revoked if, within ten (10) days after
                 receipt of notice of such breach from the non-breaching party,
                 the breaching party cures such breach to the reasonable
                 satisfaction of the other party or, if such cure cannot
                 reasonably be accomplished within such ten (10) day period, if
                 the breaching party initiates efforts to cure such breach
                 within such ten (10) day period and diligently pursues such
                 cure efforts thereafter until such cure is accom- plished; or

                 (d) The non-terminating party's repeated or continuous
                 failure, neglect or refusal to perform its duties under this
                 Agreement.

         Until the effective date of termination, Employee, if requested to do
         so by Company, shall continue to render services to Company.

         12.02  NO DUTY TO MITIGATE.  Employee shall not be required to
         mitigate the amount of any post-employment payment or benefit paid or
         provided to Employee under this Agreement by seeking other employment
         or otherwise, nor shall the amount of any such payment or benefit paid
         or provided to Employee under this Agreement be reduced or offset by
         any compensation earned by Employee as the result of employment by
         another employer or otherwise.

         13.     EFFECT OF TERMINATION.  Upon the termination or expiration of
this Agreement:  (i) Employee shall immediately return to Company any and all
Confidential Information in his possession or control (including, without
limitation, all copies thereof and all materials incorporating such
Confidential Information), (ii) Employee shall have no further obligation to
perform services for Company hereunder, provided, however, that Employee shall
continue to be bound by the terms of Sections 8 and 9 hereof, and (iii) except
to the extent specifically provided in Section 12 above, Company shall have no
further obligation to compensate or provide benefits to Employee hereunder.

         14.     BUSINESS KNOWLEDGE AND EXPERIENCE.  Notwithstanding anything
to the contrary contained in this Agreement, it is specifically understood and
agreed that Employee has, prior to entering into this Agreement, developed
significant business expertise, ideas and experience (collectively "Business
Experience") that such Business Experience, to the extent it applies to
business operations generally and not to the specific operations, technologies
or trade secrets of Company, shall not be





                                       6
<PAGE>   7
deemed to constitute Confidential Information, and nothing contained in Section
8 of this Agreement shall be deemed to prevent Employee form using such general
Business Experience in such a manner as does not violate any of the other terms
and conditions of this Agreement.

         15.     GENERAL.

         15.01  SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS.  All
         representations, warranties and covenants contained herein shall
         survive the execution of this Agreement and the consummation of the
         transactions contemplated hereby.

         15.02  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon
         and inure to the benefit of the parties hereto and their respective
         heirs, successors, assigns and legal representatives, but it shall not
         be assignable by Employee.  Any purported assignment in violation of
         the foregoing shall be invalid and of no force and effect.  No
         assignment of this Agreement shall relieve the assigning party of any
         obligation or liability hereunder.

         15.03  NOTICES.  Any notice, demand, payment, request, response or
         other communication provided for herein or given hereunder to a party
         hereto shall be in writing and shall be deemed to have been duly given
         if signed by the party giving it.  Notice shall be deemed effective
         upon delivery by hand, or on the third business day after it is
         deposited in the United States mail, postage prepaid (registered or

         accordance with the foregoing provisions.

         15.04  WAIVER.  Failure to delay in insisting upon strict compliance
         with any provision hereof shall not be deemed a waiver of such
         provision or any other provision hereof with respect to prior,
         contemporaneous or subsequent occurrences.  No waiver by either party
         of any right hereunder or of any default shall be binding upon such
