                                     PART I.

ITEM 1.           BUSINESS

THE COMPANY

         Maynard Oil Company is a Delaware corporation which was organized in
1971 to continue the oil and gas operations conducted on an individual basis by
its founders, including Mr. James G. Maynard, its Chairman of the Board and
Chief Executive Officer. The Company's principal executive office is located at
8080 N. Central Expressway, Suite 660, Dallas, Texas 75206, and its telephone
number is (214) 891-8880. Unless the context requires otherwise, as used herein,
the term "Company" refers to Maynard Oil Company and its subsidiary.

         The Company's principal line of business is the production and sale of,
and exploration and development of, crude oil and natural gas. The Company's oil
and gas operations are conducted exclusively in the United States, primarily in
the states of Texas, Oklahoma and New Mexico.

RECENT ACQUISITION ACTIVITIES

         Since January 1, 1999, the Company has purchased two sizeable groups of
producing oil and gas properties.

         In July and August, 1999, the Company purchased interests in
twenty-three producing wells located in four counties in Texas (Fayette,
Hardeman, Webb and Duval Counties) for cash consideration of $10,900,000. Total
proved reserves were estimated to be 400,000 barrels of oil and 4.9 billion
cubic feet of gas (BCF).

         On November 12, 1999, Maynard Oil bought an interest in 170 oil and gas
properties in the Permian Basin of Southeastern New Mexico and West Texas from
Questar Exploration and Production Company for $32,000,000. Total proved
reserves were estimated to be 4 million barrels of oil and 11.6 BCF of gas. To
fund this acquisition, the Company entered into a new term loan arrangement with
Bank One, Texas, which provides for the repayment of the outstanding $38,250,000
over a five year period with a maturity date of January 1, 2005. (see Note 7 to
the Consolidated Financial Statements).

2000 ACTIVITIES

         On March 16, 2000, the Company purchased eight producing wells for
$2,800,245 at auction. These wells are located in Garza, Dawson, and Ector
Counties, Texas.

OIL AND GAS OPERATIONS

         The Company is an independent oil and gas company, engaged primarily in
the production and exploration phases of the oil and gas business.  Company

                                       -2-

<PAGE>



operations include acquiring, exploring, developing, and operating crude oil
and natural gas properties.

         The Company seeks to accomplish its overall goal of increasing
hydrocarbon reserves and cash flow by selectively acquiring and exploiting
producing oil and gas properties. When possible, the Company acquires producing
properties on which it can act as operator, and thus, supervise production and
development activities.

         Prices realized from the sale of oil and gas from the Company's wells
depend on numerous factors beyond the control of the Company, including the
amount of domestic production, the importation of oil, the proximity of the
Company's property to natural gas pipelines and the capacity of such pipelines,
the market for other competitive fuels, fluctuations in seasonal demand, and
governmental regulations relative to hydrocarbon production and pricing. The
production of oil and gas is also subject to the laws of supply and demand, and
therefore, is subject to purchaser cutbacks and price reductions during periods
of oversupply. At December 31, 1999, approximately 68% of the Company's
estimated proved reserves and 72% of the 1999 production, were attributable to
crude oil and condensate on a net equivalent barrel basis (net equivalent barrel
"NEB" uses a conversion ratio of six thousand cubic feet of gas (MCF) to one net
equivalent barrel of oil) and consequently, the Company is primarily impacted by
oil markets.

         During 1999, the oil industry, including the Company, experienced a
significant upswing in the average price received from the sale of its crude
oil, exactly the opposite pricing effect than that experienced a year ago. The
weighted average price at December 31, 1998 was $10.02 per barrel of oil sold.
During the first quarter of 1999, the Company received an average of $11.44 per
barrel, which then increased to averages of $16.00, $19.81, and $22.30 per
barrel for the final three quarters of the year, respectively. Although the
price increases experienced in 1999 positively impacted the Company's
operations, the wide separation in prices between 1998 and 1999 further
emphasizes the challenges and volatility of the domestic oil and gas business
and how it is affected by conditions beyond the control of the Company.

         During the year ended December 31, 1999, three customers, accounted for
approximately 17%, 12%, and 10% respectively, of consolidated revenues. The
Company does not believe it would be adversely affected by the loss of any of
its oil or gas purchasers.

         The market price for natural gas has also fluctuated significantly from
month to month and year to year for the past several years. Like the oil market,
the Company cannot predict gas price movements with any certainty.

         Except for curtailed exploration and production activity occasionally
experienced in severe weather and normal curtailments of gas sales in summer
months, the Company does not consider its business to be seasonal and does not
carry significant amounts of inventory.

                                       -3-

         A total of seven wells were drilled during 1999, two exploratory and
five development wells. Two of the five development wells were drilled as
producers on Company-operated properties, with Maynard retaining 100% and 20%
working interest. The other three development wells were successful oil wells
drilled by another operator. The two exploratory wells were determined to be
non-productive.

GENERAL

         The oil and gas business involves intense competition in all of its
phases and, because of its size, the Company is not a significant competitive
factor in the industry. In its efforts to acquire property rights, the Company
competes with many companies having access to substantially greater financial
resources and larger technical staffs.

         The Company's oil and gas exploration efforts often involve exploratory
drilling on unproven acreage involving high risks. There is no assurance that
any oil or gas production will be obtained, or that such production, if
obtained, will be profitable. The cost of drilling, completing and operating
wells is often uncertain. Drilling may be curtailed or delayed as a result of
many factors, including title problems, weather conditions, delivery delays, and
shortages of pipe and equipment.


         The Company's operations are subject to potential hazards, inherent in
the exploration for and production of hydrocarbons, including blowouts and
fires. These and other events can cause a suspension of drilling operations,
severe damage to equipment or surrounding property, personal injury, and perhaps
even a loss of life. The Company may be subject to liability for pollution and
other damages and is subject to statutes and regulations relating to
environmental and other matters. While the Company maintains insurance against
certain of these risks, there are certain risks against which it cannot insure,
or which it may elect not to insure due to premium costs, or for other reasons.
Substantial uninsured liabilities to third parties may be incurred.

         The oil and gas operations of the Company are subject to local, state
and federal environmental regulations. To date, compliance with these
regulations by the Company has had no material effect on the Company's capital
expenditures. The Company is unable to assess or predict at this time the impact
that compliance with such environmental regulations may have on its future
capital expenditures, earnings and competitive position. The Company presently
estimates that it will not make any material capital expenditures for
environmental control facilities for its fiscal year ending December 31, 2000.

         Many facets of the Company's operations are subject to governmental
regulations. All of the Company's oil and gas properties are located in states
in which oil and gas production is regulated by state production and
conservation laws and regulations. These laws and regulations in many

                                       -4-

<PAGE>



instances also require permits for the drilling of wells, the spacing of wells,
prevention of waste, conservation of oil and natural gas and various other
requirements.

         The Company's activities are subject to taxation at all levels of
government, including taxes on income, severance of minerals, and payroll. Laws
governing taxation, protection of the environment, crude oil and natural gas
operations and production, and other crucial areas are all subject to
modification at any time.

         At March 17, 2000 the Company employed 41 persons, including one
geologist and five petroleum engineers.

ITEM 2.           PROPERTIES

         The Company's executive offices are presently located at 8080 N.
Central Expressway, Suite 660, Dallas, Texas occupying approximately 13,101
square feet of space under a lease agreement which expires in April, 2005.

         The Company's principal property holdings consist of leasehold
interests in oil and gas properties located in the United States, primarily in
Oklahoma, Texas and New Mexico. The leaseholds are continued in force so long as
production from lands under lease is maintained. The Company believes that it
has satisfactory title to its oil and gas properties. Such properties are
subject to customary royalty interests, liens incident to operating agreements,
liens for current taxes, and other burdens and minor encumbrances, easements,
and restrictions. The Company believes such burdens do not materially detract
from the value of the properties or materially interfere with their use in the
operation of the Company's business. The Company has pledged certain of its oil
and gas properties to secure its term loan.

ESTIMATED PROVED RESERVES,
FUTURE NET REVENUES AND PRESENT VALUE

         Reflected below are the estimated quantities of proved developed and
undeveloped reserves of crude oil and natural gas owned by the Company as of
December 31, 1999, 1998, and 1997. Such reserve information has been prepared by
the Company's staff of petroleum engineers and audited by the independent
petroleum consulting firm of Netherland, Sewell, and Associates, Inc. No reserve
reports with respect to the Company's proved net oil or gas reserves were filed
with any federal authority or agency during the fiscal year ended December 31,
1999.

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

YEAR ENDED DECEMBER 31, 1999 COMPARED TO DECEMBER 31, 1998
- ----------------------------------------------------------
OVERVIEW
- --------

         Maynard Oil considers 1999 a successful year from the standpoint of
adding significant oil and gas volumes to its hydrocarbon reserve base and from
the standpoint that pricing for these volumes recovered from record low levels
at year-end 1998.

LIQUIDITY AND CAPITAL RESOURCES
- -------------------------------

         During 1999, the Company made two producing property acquisitions for a
combined purchase price of $42,900,000, participated in the drilling of seven
wells, continued maintenance activities on existing properties, and made its
scheduled bank loan payments. In order to accomplish these activities, the
Company incurred additional bank debt of $32,000,000 and reduced its cash
balance by almost eight million dollars. However, 14% of the Company's assets
are represented by cash, which will be utilized along with internally

                                      -10-

<PAGE>



generated cash flow and additional bank debt, if necessary, to fund future oil
and gas activities.

RESULTS OF OPERATIONS
- ---------------------
YEAR ENDED DECEMBER 31, 1999 COMPARED TO DECEMBER 31, 1998
- ----------------------------------------------------------

         For the year ended December 31, 1999, the Company earned eighty-nine
cents per share compared to the prior year loss of one dollar and sixty cents
per share. The loss in 1998 was primarily related to oil and gas price
reductions which resulted in lower oil and gas revenues and a non-cash
impairment charge to oil and gas properties of $1.18 per share.

         Oil and gas revenues rose $7,226,189, or almost 45% between the two
years, primarily due to price increases and higher gas volumes resulting from
the current year property acquisitions. Oil and gas prices were $5.26 per barrel
and forty-six cents per thousand cubic feet (mcf) higher than a year ago. Gas
volumes increased approximately 40% while oil volumes declined slightly more
than 3% during this one year period.

         On a net equivalent barrel basis, lease operating expense declined
twenty cents per NEB from $5.91 in 1998 to $5.71 in 1999 because expense
workovers were less during the current period than the same period a year ago.

         Exploration costs increased $141,890, or 36%, during 1999 primarily
because the Company drilled two exploratory dry holes in the current year, which
are expensed under the successful efforts method of accounting since no
commercial hydrocarbon reserves were found. During 1998, two exploratory wells
were productive and capitalized as oil and gas property.

         General and administrative expense category reflects a $513,470
increase which is primarily the result of phantom stock adjustments. During the
current year, phantom stock expense was charged $214,875, while in 1998, general
and administrative expenses included a phantom stock credit of $262,625. Phantom
stock charges and credits arise as a result of stock price fluctuations. Closing
stock prices at December 31, 1999, 1998, and 1997 were $9.75, $7.50, and $10.25
respectively.

         Depreciation and amortization expense was reduced almost 41% from prior
year levels. Under the successful efforts method of accounting, costs of oil and
gas properties are amortized on a unit-of-production method based on estimated
proved reserves. During 1998, the effects of lower oil and gas prices reduced
the estimated quantities of recoverable proved reserves which resulted in
increased expense. Likewise, higher product prices in the current year increased
the estimated quantities of recoverable proved reserves and decreased the
average depletion rate. On a net equivalent barrel basis, the current rate was
$4.26 per NEB compared with $7.58 per NEB last year. Last year's impairment
charge amounted to $6.74 per NEB. If the 1998 write down of oil and gas
properties had not occurred, thus leaving the impairment amount capitalized, the
current year depreciation and amortization expense would have increased
forty-six cents per NEB.


                                      -11-

<PAGE>



         Average oil prices for December, 1999 were $23.47 per barrel compared
with an average of $10.02 a year ago. Consequently, there was no indication the
carrying amount of the Company's assets should be assessed for recoverability,
and thus there was no impairment charge during the current year.

         Interest expense decreased $117,644 due to scheduled bank note payments
and the resulting lower average principal amounts outstanding. For future
periods, the amount of interest expense should rise because of the $32,000,000
increase in bank debt which occurred in late 1999.

         Income tax expense reflects a charge of $2,793,000 during the current
period while the prior year included a tax benefit of $4,081,856 to reflect the
losses related to pricing reductions.

YEAR ENDED DECEMBER 31, 1998 COMPARED TO DECEMBER 31, 1997
- ----------------------------------------------------------
OVERVIEW
- --------

         1998 was a challenging year for Maynard Oil Company, as well as all
others involved in the energy sector, attempting to deal with a virtual price
collapse for its hydrocarbon products. For 1998, the Company recorded a net loss
of $7,815,509, primarily related to oil and gas price reductions, which resulted
in lower oil and gas revenues, as well as a non cash impairment charge of
$8,754,846. Without this non cash write off, the Company would have reported a
loss of approximately $2,075,000 (net of tax).

LIQUIDITY AND CAPITAL RESOURCES
- -------------------------------

         During 1998, the Company purchased three fields in West Texas for cash
consideration of approximately $2,684,000. The Company also made its scheduled
bank loan payments and continued maintenance activities on existing properties,
all of which reduced the cash balance by approximately $3,700,000 in 1998.
However, almost 35% of the Company's total assets, as reflected on its 1998
balance sheet, is represented by cash, which would be utilized along with
additional bank debt to finance future property acquisitions.

RESULTS OF OPERATIONS
- ---------------------
YEAR ENDED DECEMBER 31, 1998 COMPARED TO DECEMBER 31, 1997
- ----------------------------------------------------------

         The net loss for 1998 was $7,815,509 compared to net income of
$4,455,355 for 1997 an adverse change in financial results over the two year
period of $12,270,864.

         Oil and gas revenues declined $10,311,196, or almost 39% between the
two years, primarily due to product price reductions. Oil prices plummeted seven
dollars per barrel during the period and gas prices fell forty-six cents per
MCF, accounting for approximately $8,600,000 of the revenue reduction. Oil and
gas revenues were also negatively impacted by oil and gas volume reductions of
7% and 16%, respectively.


                                      -12-

<PAGE>



         Lease operating expenses decreased 14%, from $10,124,212 in 1997 to
$8,722,565 in 1998, primarily due to lower production taxes resulting from the
significant decline in oil and gas prices. On a net equivalent barrel basis,
this decrease was fifty-two cents per NEB, from $6.43 per NEB in 1997 to $5.91
per NEB during the current year.

         Exploration costs decreased from $838,580 in 1997 to $391,718
currently, a 53% decline, essentially due to a reduction in seismic costs which
were partially offset by higher impairments of undeveloped acreage. Because the
Company follows the successful efforts method of accounting, the Company's
results of operations may be adversely affected during any accounting period in
which seismic costs, exploratory dry hole costs, and unproved property
impairments are expensed.

         General and administrative expenses increased approximately 20% in
1998, due primarily to decreased amounts accrued under an employee benefit plan,
which is based upon stock price (see Note 8 to the Company's Consolidated
Financial Statements). Last year, general and administrative expense was
credited $518,563 as the Company's stock price fell from $18.75 per share at the
end of 1996 to $10.25 per share at the end of 1997. During the current calendar
year, the Company's general and administrative expense was credited $262,625 to
reflect a further stock price reduction from $10.25 per share to $7.50 per share
at the end of 1998. Thus, the Company ended 1998 with a liability of $234,750
representing future cash payments to which various employees covered by this
plan are entitled whenever their employment by the Company is ended.

         Depreciation and amortization expense increased 22% due to an increase
in the Company's average depletion rate. Under the successful efforts method of
accounting, costs of oil and gas properties are amortized on a
unit-of-production method based on estimated proved reserves. The increase in
the Company's average depletion rate was attributable to the effects of lower
oil and gas prices on estimated quantities of proved reserves. These estimates
relate to end-of-year product prices, which were $15.72 per barrel of oil and
$2.05 per MCF of natural gas at the end of 1997 compared to $10.02 per barrel of
oil and $1.86 per MCF of natural gas at the end of 1998. On a net equivalent
barrel basis, the current depreciation and amortization expense rate was $7.58
per NEB compared with $5.63 per NEB for the prior twelve months, a 35% increase.

         During 1998, the Company also recognized a non-cash impairment charge
to oil and gas properties in the amount of $8,754,846 compared to $227,879 in
the prior year. Under generally accepted accounting principles, the Company must
compare the carrying value of its oil and gas properties with the undiscounted
value of its future net revenues from the properties. Should this comparison
indicate non-recoverability of the carrying costs, an impairment is recognized
based upon estimates of discounted value. The significant reduction in product
pricing impacted this comparison and caused the current year writedown.


                                      -13-

<PAGE>



         Interest expense decreased approximately $438,000, or 30% due to
scheduled bank note payments for 1998 and the resulting lower principal amounts
outstanding.

         The Company recognized a tax benefit of $4,081,856 during 1998 compared
with tax expense of $2,157,500 during the prior year. This current year tax
benefit relates to the tax effects of the revenue reductions, expenses and
impairments discussed above.

RECENT ACCOUNTING PRONOUNCEMENTS
- --------------------------------

         In June 1998, the Financial Accounting Standards Board issued Statement
No. 133 ("SFAS 133"), "Accounting for Derivative Instruments and Hedging
Activities." SFAS 133 establishes accounting and reporting standards for
derivative instruments and for hedging activities. It requires enterprises to
recognize all derivatives as either assets or liabilities in the balance sheet
and measure those instruments at fair value. The requisite accounting for
changes in the fair value of a derivative will depend on the intended use of the
derivative and the resulting designation. The Company must adopt SFAS 133
effective January 1, 2001. Based on the Company's outstanding derivative
contracts, the Company believes that the impact of adopting this standard would
not have a material adverse affect on the Company's operations or consolidated
financial condition. However, no assurances can be given with regard to the
level of the Company's derivative activities at the time SFAS 133 is adopted or
the resulting effect on the Company's operations or consolidated financial
condition.

YEAR 2000 DISCLOSURE
- --------------------

         The Company has not experienced any problems related to the year 2000
date change, nor have its suppliers experienced any difficulties with respect to
the products and services provided to the Company.

ITEM 7.A.         QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

COMMODITY RISK
- --------------

         The Company's primary commodity market risk exposure is to changes in
the pricing applicable to its oil production, which is normally priced with
reference to a defined benchmark, such as light, sweet crude oil traded on the
New York Mercantile Exchange (WTI). Actual prices received vary from the
benchmark depending on quality and location differentials. The markets for crude
oil historically have been volatile and are likely to continue to be volatile in
the future.

         From time to time, the Company enters into financial market
transactions, including collars, with creditworthy counterparties, primarily to
reduce the risk associated with the pricing of a portion of the oil and natural
gas that it sells. The policy is structured to underpin the Company's planned
revenues and results of operations.

         During 1999, the Company entered into a derivative financial instrument
whereby the Company has hedged 2,500 barrels of daily production from November
1, 1999 through June 30, 2000 with a ceiling price of $23.90/bbl and a floor
price of $14.00/bbl. The contracts call for a monthly settlement such that if
the average WTI for the month is greater than $23.90/bbl, The Company remits to
the counterparty the excess times the number of barrels hedged during the month.
Conversely, if the average WTI for the month is less than $14.00/bbl, the
counterparty pays the Company for the difference times the number of barrels
hedged during the month. If the average WTI for the month falls between
$14.00/bbl and $23.90/bbl, no settlement is made. As a result of this
arrangement, the Company's oil and gas revenues were reduced by $234,673 during
1999.

INTEREST RATE RISK
- ------------------

         While the Company does have interest rate risk associated with the
$38.25 million in outstanding borrowing as of December 31, 1999, they do not
consider the risk to have a material impact on the Company's operations. As
such, the Company does not hedge against interest rate risk exposure.

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



To the Board of Directors and Shareholders of
 Maynard Oil Company

In our opinion, the consolidated financial statements listed in the accompanying
index present fairly, in all material respects, the financial position of
Maynard Oil Company and its subsidiary at December 31, 1999 and 1998, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1999 in conformity with accounting principles
generally accepted in the United States. In addition, in our opinion, the
financial statement schedule listed in the accompanying index presents fairly,
in all material respects, the information set forth therein when read in
conjunction with the related Consolidated Financial Statements. These financial
statements and the financial statement schedule are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements and the financial statement schedule based on our audits.
We conducted our audits of these statements in accordance with auditing
standards generally accepted in the United States, which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion expressed
above.

                       MAYNARD OIL COMPANY AND SUBSIDIARY
                   Notes to Consolidated Financial Statements


(1)       Summary of Significant Accounting Policies
          ------------------------------------------

          Business Activity
          -----------------

          Maynard Oil Company (the Company) is engaged in the acquisition,
          exploration, development, production and sale of crude oil and natural
          gas in the Continental United States, primarily in the states of
          Texas, Oklahoma and New Mexico.

          Principles of Consolidation
          ---------------------------

          The consolidated financial statements include the accounts of Maynard
          Oil Company and its wholly-owned subsidiary. All significant
          intercompany balances and transactions have been eliminated in
          consolidation.

          Cash Equivalents
          ----------------

          Cash equivalents are highly liquid investments purchased with an
          original maturity of three months or less.

          Property and Equipment
          ----------------------

          The Company follows the "successful efforts" method of accounting for
          its costs of acquisition, exploration and development of oil and gas
          properties. Intangible drilling and development costs related to
          development wells and successful exploratory wells are capitalized,
          whereas the costs of exploratory wells which do not find proved
          reserves are expensed. All geological and geophysical costs not
          reimbursed are expensed as incurred. Costs of acquiring unproved
          leases are evaluated for impairment until such time as the leases are
          proved or abandoned. In addition, unamortized costs at a field level
          are reduced to fair value if the sum of expected undiscounted future
          cash flows are less than net book value.

          Depreciation and amortization of producing properties is computed
          using the unit-of-production method based upon estimated proved
          recoverable reserves. Depreciation of other property and equipment is
          calculated using the straight-line method based upon estimated useful
          lives ranging from two to ten years.

          Maintenance and repairs are charged to expense as incurred. Renewals
          and betterments are capitalized. When assets are sold, retired or
          otherwise disposed of, the applicable costs and accumulated
          depreciation and amortization are removed from the accounts, and the
          resulting gain or loss is recognized.

          Revenue Recognition
          -------------------

          The Company recognizes oil and gas sales from its interests in
          producing wells under the sales method of accounting. Under the sales
          method, the Company recognizes revenues based on the amount of oil and
          natural gas sold to purchasers, which may be different from the
          amounts to which the Company is entitled based on its interest in the
          properties. Gas balance obligations as of December 31, 1999, 1998 and
          1997 were not significant.

          Overhead Reimbursement Fees
          ---------------------------

          Prior to 1999, overhead charges billed to working interest owners,
          including the Company, have been classified as a reduction of general
          and administrative expenses in the Consolidated Statements of
          Operations with the Company's working interest share being included in
          operating expenses. For 1999, the Company reduced general and
          administrative expenses by only the amounts actually due from outside
          working interest owners and has reclassified the expenses for 1998 and
          1997 to conform with the 1999 presentation. The effect of this
          reclassification for the prior two years is as follows:

</TABLE>

          Deferred Income Taxes
          ---------------------

          The Company recognizes deferred tax liabilities and assets for the
          expected future tax consequences of temporary differences between the
          tax and financial reporting bases of the Company's assets and
          liabilities by applying enacted tax rates. A valuation allowance is
          established to reduce deferred tax assets if it is more likely than
          not that the related tax benefits will not be realized.

          Derivative Financial Instruments
          --------------------------------

          The Company periodically enters into commodity hedge contracts,
          including caps and floors which require payments to (or receipts from)
          counterparties based on the differential between a fixed price and a
          variable price for a fixed quantity of crude oil or natural gas
          without the exchange of underlying volumes. The notional amounts of
          these derivative financial instruments are based on expected
          production from existing wells. The Company uses these derivative
          financial instruments to manage market risks resulting from
          fluctuations in commodity prices.

                                      -26-

<PAGE>



          The derivative financial instruments held by the Company are not
          leveraged and are held for purposes other than trading.

          Correlation of the hedge contracts is determined by evaluating whether
          hedge contract gains and losses will substantially offset the effects
          of price changes on the underlying crude oil and natural gas sales
          volumes. To the extent that correlation exists between the hedge
          contracts and the underlying crude oil and natural gas sales volumes,
          realized gains or losses and related cash flows arising from the hedge
          contracts are recognized as a component of oil and natural gas sales
          in the same period as the sale of the underlying volumes. To the
          extent that correlation does not exist between the hedge contracts and
          the underlying crude oil and the natural gas sales volumes, realized
          gains or losses and related cash flows arising from the hedge
          contracts are recognized in the period as a component of other income.
          The fair market value of any hedge contract that does not meet the
          correlation test outlined above is recorded as a deferred gain or loss
          on the balance sheet and is adjusted to current market value at each
          balance sheet date with any deferred gains or losses recognized as a
          component of other income.

          In the event that management decides to terminate a hedge contract,
          generally accepted accounting principles require that any gains or
          losses upon termination be carried forward and recognized as a
          component of oil and natural gas sales in the period in which the
          underlying volumes are sold.

          Income per Common Share
          -----------------------

          The Company does not have a complex capital structure, and
          consequently, net income per common share is computed using the
          weighted average number of common shares outstanding during each year.
          Basic and diluted earnings per share were the same for 1999, 1998 and
          1997.

          Segment Information
          -------------------

          All of the Company's oil and gas properties and related operations are
          located in the United States and management has determined that the
          Company has one reportable segment.

          The Use of Estimates in Preparing Financial Statements
          ------------------------------------------------------

          The preparation of financial statements in conformity with generally
          accepted accounting principles requires management to make estimates
          and assumptions that affect the reported amounts of assets,
          liabilities, disclosures of gain and loss contingencies at the date of
          the financial statements and reported amounts of revenues and expenses
          during the reporting period. Since estimates are made based on all
          information available at the time, it is reasonably possible in the
          near term a change in an estimate may occur or actual amounts may
          differ from estimated amounts.

                                      -27-

          Reclassifications
          -----------------

          Certain reclassifications of prior period statements have been made to
          conform with the 1999 presentation.

(2)       Fair Value of Financial Instruments, Risk Management, and
          ---------------------------------------------------------
          Concentrations of Credit Risk
          -----------------------------

          Fair Value of Financial Instruments
          -----------------------------------

          The carrying amounts of cash and cash equivalents, accounts
          receivable, and accounts payable approximate fair value because of the
          short maturity of these instruments. The carrying amount of long-term
          debt, including the current portion, approximates fair value because
          the interest rate on this instrument changes with market interest
          rates.

          Risk Management
          ---------------

          During 1999, the Company entered into a derivative financial
          instrument whereby the Company has hedged 2,500 barrels of daily
          production from November 1, 1999 through June 30, 2000 with a ceiling
          price of $23.90/bbl and a floor price of $14.00/bbl. The contracts
          call for a monthly settlement such that if the average WTI for the
          month is greater than $23.90/bbl, Maynard remits to the counterparty
          the excess times the number of barrels hedged during the month.
          Conversely, if the average WTI for the month is less than $14.00/bbl,
          the counterparty pays Maynard for the difference times the number of
          barrels hedged during the month. If the average WTI for the month
          falls between $14.00/bbl and $23.90/bbl, no settlement is made. As a
          result of this arrangement, the Company's oil and gas revenues were
          reduced by $234,673 during 1999.

          Concentration of Credit Risks
          -----------------------------

          Financial instruments, which potentially subject the Company to
          concentrations of credit risk, consist principally of cash and cash
          equivalents and accounts receivable. The Company places its cash and
          cash equivalents with high credit quality institutions. With respect
          to accounts receivable, these financial instruments primarily pertain
          to oil and gas sales and joint interest billings. These accounts
          receivable are due from small to mid-size companies engaged
          principally in oil and gas activities. The Company performs ongoing
          credit evaluations of its customers' financial condition and,
          generally, requires no collateral from its customers. Payment terms
          are on a short-term basis and in accordance with industry standards.

          During the years ended December 31, 1999 and 1997, oil and gas sales
          to three customers, amounting to approximately $4,143,000, $2,868,000,
          and $2,457,000 and $5,698,000, $5,067,000 and $3,783,000,
          respectively, each accounted for more than 10% of total consolidated
          revenues. For the year ended December 31, 1998, oil and gas sales to
          four customers, amounting to approximately $2,449,000, $2,277,000,
          $2,183,000, and

                                      -28-

<PAGE>



          $2,144,000, respectively, each accounted for more than 10% of total
          consolidated revenues.

(3)       Subsequent Event
          ----------------

          On March 16, 2000, the Company purchased eight producing wells for
          $2,800,245 at auction. These wells are located in Garza, Dawson, and
          Ector Counties, Texas.

(4)       Acquisitions (Reserve information is unaudited)
          -----------------------------------------------

          During 1999, the Company consummated two separate producing property
          acquisitions for a gross purchase price of $42,900,000. In July and
          August of 1999, the Company purchased interests in twenty-three
          producing oil and gas wells located in four counties in Texas
          (Fayette, Hardeman, Webb, and Duval) at auction. Estimated proved
          reserves associated with this transaction approximated 400,000 barrels
          of oil and 4.9 billion cubic feet of gas (BCF). Total consideration
          paid was $10,900,000.

          On November 12, 1999, Maynard Oil bought an interest in 170 oil and
          gas properties in the Permian Basin of Southeastern New Mexico and
          West Texas from Questar Exploration and Production Company for
          $32,000,000. Total proved reserves were estimated to be 4 million
          barrels of oil and 11.6 bcf of gas. In conjunction with this
          transaction, the Company entered into a new term loan arrangement with
          Bank One, Texas.

          The above acquisitions were accounted for as purchases, and their
          results of operations are included in the Consolidated Statements of
          Operations from the closing dates. In connection with the Questar
          purchase, results of operations from the effective date through the
          closing date were recorded as purchase price adjustments.

          The following table presents unaudited pro forma operating results for
          the Questar transaction as if this $32,000,000 acquisition had
          occurred on January 1, 1998.

(5)       Impairment of Long-Lived Assets
          -------------------------------

          Oil and gas prices fell from an average of $15.72 per barrel and $2.05
          per mcf at the end of 1997 to averages of $10.02 per barrel and $1.86
          per mcf, at the end of 1998. Consequently, the Company performed an
          impairment evaluation of its oil and gas properties and recognized a

                                      -29-

          non-cash impairment of $8,754,846 in December 1998 to account for
          those properties whose investment would not be recoverable under the

</TABLE>

          Effective November 12, 1999, the Company executed a new loan agreement
          with Bank One, Texas, increasing its outstanding loan from $6,250,000
          to $38,250,000 in connection with the acquisition of producing
          properties discussed in Note 4.

          The term note permits the Company to choose between three interest
          rate options and to specify what portion of the loan is covered by a
          specific interest rate option and the applicable funding period to
          which the

                                      -30-

<PAGE>



          interest rate option is to apply.  The interest rate options are as
          follows:

                  (1)      Bank's prime lending rate
                  (2)      Bank's certificate of deposit rate
                  (3)      London interbank eurodollar rate (Eurodollar)

          At December 31, 1999, interest on the bank term loan was at a rate of
          approximately 6.99%.

          The credit agreement contains various financial covenants related to
          working capital, net worth, and cash flow. Additionally, the debt
          agreement places certain limitations on the incurrence of additional
          debt and prohibits the payment of dividends.

(8)       Employee Incentive Plans
          ------------------------

          In August 1989, an employee incentive plan was adopted, whereby stock
          participation units might be granted to officers and key employees.
          Such stock participation units entitle a participant to a cash payment
          following termination of employment in an amount equal to the excess,
          if any, of the fair market value of one share of the Company's common
          stock over a share price specified on the date of grant, multiplied by
          the number of vested units. The units vest over a five year period
          with 25% vesting after two years and the remainder in three equal
          annual installments. For the year ended December 31, 1989, 73,000
          units were awarded to certain employees at a price of $4.50 per share
          of which 49,500 units remain outstanding at December 31, 1999, all of
          which are 100% vested. During August 1993, 52,000 additional units
          were awarded at $5.625 per share of which 46,000 units remain
          outstanding and are also 100% vested. Earnings are charged and
          credited over the life of the units for fluctuations in stock prices
          from $4.50 per share and $5.625 per share. During the current year,
          operations were charged $111,375 and $103,500 in regard to the stock
          participation units granted in 1989 and 1993, respectively. These
          charges reflect the increase in closing stock prices from $7.50 per
          share at December 31, 1998 to $9.75 per share at December 31, 1999.
          During 1998 and 1997, respectively operations were credited $262,625
          and $518,563.

          Income tax expense(benefit) for the three years ended December 31,
          1999 differs from the amount computed by applying the applicable U.S.
          corporate income tax rate of 34% to income (loss) before income taxes.
          The reasons for this difference are as follows:

          For both 1999 and 1998, the net deferred tax calculation resulted in
          the recognition of a deferred tax asset. After review by management,
          it was determined no valuation allowance was deemed necessary.

(10)      Employee Benefit Plans
          ----------------------

          The Company adopted a noncontributory defined contribution retirement
          plan for all full-time employees age 21 or older who have completed
          one year of service. The plan provides for a minimum annual
          contribution by the Company equal to 3% of an employee's base salary
          plus overtime compensation. At its discretion, the Company may also
          make supplemental contributions to the plan. For calendar 1997, 1998
          and 1999, the Company elected to contribute 5% for each employee
          covered by this plan. Under this plan, amounts equal to retirement
          plan expense are funded annually, which amounted to $106,462, $103,458
          and $99,313, respectively, for the years ended December 31, 1999, 1998
          and 1997 respectively.


                                      -32-

<PAGE>



          The Company also has a profit sharing plan pursuant to Section 401 of
          the Internal Revenue Code, whereby participants may contribute a
          percentage of compensation. The Plan provides for a matching
          contribution by the Company equal to one-half of the employee's
          percentage contribution up to the first 10% of compensation for 1999,
          1998, and 1997. During this same three year period, the Company's
          matching portion amounted to $93,823, $91,911, and $91,302,
          respectively.

(11)      Contingencies and Commitments
          -----------------------------

          The Company is a defendant in certain non-environmental litigation
          arising from operations in the normal course of business. While it is
          not feasible to determine the outcome of these actions, it is the
          Company's opinion that the ultimate outcome of the litigation will not
          have a material adverse effect on the financial position or results of
          operations of the Company.

          All of the Company's operations are generally subject to Federal,
          state and local environmental regulations. To the best of management's
          knowledge, the Company is in substantial compliance with such laws and
          regulations.

          The Company leases office space and certain equipment under various
          operating leases which expire over the next five years. All leases
          require the payment of taxes and insurance, and the office lease
          requires the Company to pay its pro rata share of increases in
          maintenance expense above that prevailing in base years. Management
          expects that in the normal course of business, leases will be renewed
          or replaced by other leases. The Company extended its office space
          lease, which was scheduled to terminate April 30, 2000, for an
          additional five years, such that the expiration date is now April 30,
          2005. Rent expense for the three years ended December 31, 1999 was
          $362,443, $341,443, and $321,001, respectively.

          Minimum payments for operating leases having initial or noncancellable
          terms in excess of one year are as follows:

                                                   2000               $  276,750

         Oil and Gas Reserve Quantities
         ------------------------------

         The following unaudited tables represent the Company's estimates of its
         proved oil and gas reserves. 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 were evaluated by the
         Company's staff of petroleum engineers and audited by independent
         petroleum engineers. It is their opinions that the reserve quantity and
         present value information in the following tables complies with the
         applicable rules and regulations of the SEC. All of the Company's
         reserves are located within the United States.

         WHEREAS,  Borrower and Bank have agreed to make certain  amendments  to
the Restated Loan Agreement and restate the same in its entirety.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained, the parties hereto agree as follows:

have the  following  meanings  (all terms  defined in this Section 1 or in other

when used in the plural and vice versa):

                  "Affiliate"   shall  mean  any  Person   which,   directly  or
         indirectly,  controls, is controlled by or is under common control with

         "under common control with"), as used with respect to any Person, shall
         mean a member of the board of  directors,  a partner  or an  officer of
         such  Person,  or  any  other  Person  with  possession,   directly  or
         indirectly,  of the  power to  direct  or cause  the  direction  of the
         management  and  policies of such  Person,  through the  ownership  (of
         record,  as  trustee,  or  by  proxy)  of  voting  shares,  partnership
         interests or voting rights, through a management contract or otherwise.
         Any Person owning or controlling  directly or indirectly ten percent or

         other  equity  interest  of  another  Person  shall be  deemed to be an
         Affiliate of such Person.

                  "Agreement"  shall  mean  this  Agreement  as the  same may be
         amended, modified or restated from time to time.

         interest which Agent may charge on loans to its customers). Each change
         in the Base  Rate  shall  become  effective  without  prior  notice  to

         reborrowing of a Eurodollar Loan as a Base Rate Loan and (ii) ending on
         the date on which  Borrower  converts  such  portion  to a CD Loan or a
         Eurodollar Loan.

                  "Base Rate Loans"  shall mean any loan during any period which
         bears  interest  based upon the Base Rate or which would bear  interest
         based upon the Base Rate if the Maximum  Rate ceiling was not in effect
         at that particular time.

         Continuation/Conversion  Notice as provided  in Sections  4(c) and (d);

         simple average (rounded upwards, if necessary,  to the next highest .01
         of 1%) of the rates per annum  offered  to Bank at  approximately  9:00
         a.m.  (Dallas  time) on the first day of such CD  Interest  Period,  by
         three  certificate of deposit dealers of recognized  standing,  for the
         purchase at face value of a domestic  certificate  of deposit from Bank

                  maturing Eurodollar Loans to Base Rate Loans.

                           (iii)  CD  Loans.  Borrower  agrees  to pay  interest
                  calculated  on the  basis of  actual  days  elapsed  in a year
                  consisting  of 360 days with  respect to the unpaid  principal
                  amount of each CD Loan from the day the  proceeds  thereof are
                  made  available  to  Borrower   until  maturity   (whether  by
                  acceleration  or otherwise),  at a rate per annum equal to the
                  lesser of (i) the Maximum Rate, or (ii) the CD Rate.  Interest
                  with  respect  to  each  CD  Loan  shall  be  payable  on  the

         give  prompt  notice  to the  Borrower  of  each  rate of  interest  so
         determined  and its  determination  thereof shall be conclusive  absent
         error.

                  (c)  Conversion  Option.  Borrower may elect from time to time
         (i) to  convert  all or any part of its  Eurodollar  Loans to Base Rate
         Loans or CD Loans by giving Bank irrevocable notice of such election at
         least two (2)  Eurodollar  Business  Days prior to 10:00 a.m.  (Dallas,
         Texas  time) in the form of Exhibit  "B" (the  "Conversion/Continuation
         Notice")  to be  received on the  conversion  date and such  conversion
         shall be made on the requested  conversion date, provided that any such
         conversion of Eurodollar Loan shall only be made on the last day of the
         Eurodollar Interest Period with respect thereof, (ii) to convert all or
         any part of its Base  Rate  Loans  to  Eurodollar  Loans or CD Loans by
         giving the Bank an irrevocable  Conversion/Continuation Notice at least
         three (3)  Eurodollar  Business  Days (in the case of a  conversion  to
         Eurodollar Loans) or two (2) Business Days (in the case of a conversion
         to  CD  Loans)  prior  to  the  proposed  conversion,   specifying  the
         Eurodollar  Interest Period or the CD Interest Period,  as the case may

         Eurodollar  Business Day or a Business  Day, as the case may be, on the

                                     - 14 -

<PAGE>



         (iii) to convert all or any part of its CD Loans to Eurodollar Loans or
         Base    Rate    Loans   by    giving    the    Bank   an    irrevocable
         Conversion/Continuation  Notice at least three (3) Eurodollar  Business
         Days  (in the  case  of  conversion  to  Eurodollar  Loans)  or two (2)
         Business  Days (in the case of  conversion to Base Rate Loans) prior to
         the proposed conversion,  specifying the Eurodollar Interest Period, if
         any  therefore,  and such  conversion  shall  be made on the  requested
         conversion  date  or,  if  such  requested  conversion  date  is  not a
         Eurodollar  Business Day or a Business  Day, as the case may be, on the
         next  succeeding  Eurodollar  Business  Day,  as the case may be.  Each
         change in an Interest  Option made  pursuant to this Section 4(c) shall
         be deemed a  reborrowing  (notwithstanding  that the  unpaid  principal
         amount  of the  Term  Loan is not  thereby  changed)  of a CD  Loan,  a
         Eurodollar  Loan or a Base Rate Loan into which such change was made on
         the date of such change. If no Conversion/Continuation  Notice is given
         with respect to all or any portion of a Loan,  Borrower shall be deemed
         to have  elected to  reborrow  such  portion of the Loan as a Base Rate
         Loan.

                  (d) Continuation  Option.  Prior to the termination of each CD
         Interest Period or Eurodollar  Interest  Period,  Borrower may give the
         Bank a Conversion/Continuation  Notice electing to continue all or part
         of the  loan  related  thereto  as the  same  type  of  loan  upon  the
         expiration of such CD Interest  Period or Eurodollar  Interest  Period.
         Such  Conversion/Continuation  Notice  shall  be given to Bank at least
         three (3)  Eurodollar  Business Days prior to the  termination  of such
         Eurodollar  Interest Period and at least two (2) Business Days prior to
         the termination of such CD Interest Period and shall specify the length
         of the succeeding CD Interest Period or Eurodollar  Interest Period, as
         the case may be (subject to the  provisions of the  definitions of such
         term),  selected  by  Borrower  with  respect  to such  portion.  If no
         Conversion/Continuation  Notice  is given  with  respect  to all or any
         portion of a Loan, Borrower shall be deemed to have elected to reborrow
         such portion of the Loan as a Base Rate Loan.

                  (e) Recoupment. If at any time the applicable rate of interest
         selected  pursuant to Sections  4(a)(i),  4(a)(ii) or  4(a)(iii)  above
         shall exceed the Maximum Rate, thereby causing the interest on the Note
         to be limited to the Maximum Rate, then any subsequent reduction in the
         interest rate so selected or subsequently selected shall not reduce the
         rate of  interest  on the Note below the  Maximum  Rate until the total
         amount of  interest  accrued on the Note  equals the amount of interest
         which  would  have  accrued  on the Note if the rate or rates  selected
         pursuant to Sections 4(a)(i), (ii) or (iii), as the case may be, had at
         all times been in effect.

                  (f) Options  Upon  Default.  Notwithstanding  anything in this
         Section  4 to the  contrary,  no CD  Loan  or  Eurodollar  Loan  may be
         continued  as such when any Default or Event of Default  has  occurred,
         but  each  such CD Loan  or  Eurodollar  Loan  shall  be  automatically
         converted to a Base Rate Loan on the last day of each  Interest  Period
         applicable to such CD Loan or Eurodollar Loan.

         to Bank for  Certificates  of  Deposit  for the CD  Interest  Period is
         available;  or  (ii) in  good  faith  determines  that  the  Eurodollar
         Interest Rate or the CD Interest Rate will not  adequately  reflect the
         cost to the Bank of  maintaining  or  funding  the Fixed Rate Loans for
         such  Interest  Period,  the  obligations  of  the  Bank  to  make  the
         Eurodollar  Loans or CD Loans,  as the case may be,  shall be suspended
         until such time such Bank in its sole discretion  reasonably  exercised
         determines  that the event  resulting in such  suspension has ceased to
         exist. If Bank shall make such  determination  it shall promptly notify
         Borrower in writing,  and Borrower  shall either repay the  outstanding
         Eurodollar Loans or CD Loans, as the case may be, owed to Bank, without
         penalty,  on the last day of the current Interest Period or convert the
         same to Base Rate or CD Loans in the case of  Eurodollar  Loans or Base
         Rate or Eurodollar Loans in the case of CD Loans on the last day of the
         then current Interest Period for such Fixed Rate Loan.

                  (b)  Reserve  Requirements.  In the event of any change in any
         applicable  law,  treaty  or  regulation  or in the  interpretation  or
         administration  thereof,  or in the  event  any  central  bank or other
         fiscal monetary or other authority having jurisdiction over the Bank or
         the loans  contemplated by this Agreement shall impose,  modify or deem
         applicable  any reserve  requirement  of the Board of  Governors of the
         Federal  Reserve  System on any Fixed Rate Loan or loans,  or any other
         reserve,  special  deposit,  or some  requirements  against  assets to,
         deposits with or for the account of, or credit extended by, the Bank or
         shall impose on the Bank or the London  interbank  market,  as the case
         may be, any other condition  affecting this Agreement or the Fixed Rate
         Loans and the result of any of the foregoing is to increase the cost to
         the Bank in making or maintaining its Fixed Rate Loans or to reduce any
         amount (or the  effective  return on any  amount)  received by the Bank
         hereunder,  then Borrower shall pay to the Bank upon demand of the Bank
         as additional interest on the Note evidencing the Fixed Rate Loans such
         additional  amount  or  amounts  as will  reimburse  the  Bank for such
         additional  cost or such  reduction.  The Bank  shall  give  notice  to
         Borrower upon becoming aware of any such change or imposition which may
         result in any such increase or reduction. A certificate of Bank setting
         forth the basis  for the  determination  of such  amount  necessary  to
         compensate  Bank as aforesaid  shall be delivered to Borrower and shall
         be conclusive as to such determination and such amount, absent error.

                  (c) Taxes.  Both principal and interest on the Note evidencing
         the Fixed Rate Loans are payable  without  withholding or deduction for
         or on account  of any  taxes.  If any taxes are levied or imposed on or
         with  respect  to the Note  evidencing  the Fixed  Rate Loans or on any
         payment on the Note  evidencing  the Fixed Rate Loans made to the Bank,
         then, and in any such

                                     - 16 -

<PAGE>



         event,  Borrower  shall  pay to the Bank  upon  demand of the Bank such
         additional  amounts as may be  necessary  so that every net  payment of
         principal  and  interest on the Note  evidencing  the Fixed Rate Loans,
         after  withholding  or  deduction  for or on account of any such taxes,
         will not be less than any amount provided for herein.  In addition,  if
         at any time when the Fixed Rate Loans are  outstanding any laws enacted
         or promulgated,  or any court of law or governmental  agency interprets
         or administers any law, which, in any such case, materially changes the
         basis of taxation of payments to the Bank of  principal  of or interest
         on the Note  evidencing  the Fixed Rate  Loans by reason of  subjecting
         such  payments  to double  taxation  or  otherwise  (except  through an
         increase  in the rate of tax on the  overall  net  income of Bank) then
         Borrower  will pay the amount of loss to the  extent  that such loss is
         caused by such a change.  The Bank shall give notice to  Borrower  upon
         becoming  aware of the amount of any loss  incurred by the Bank through
         enactment or promulgation of any such law which materially  changes the
         basis of taxation  of  payments  to the Bank.  The Bank shall also give
         notice on becoming  aware of any such enactment or  promulgation  which
         may result in such  payments  becoming  subject to double  taxation  or
         otherwise.  A  certificate  of any Bank setting forth the basis for the
         determination of such loss and the computation of such amounts shall be
         delivered to Borrower and shall be conclusive of such determination and
         such amount, absent error.

                  (d)  Change in Laws.  If at any time any new law or any change
         in existing laws or in the  interpretation  of any new or existing laws
         shall make it unlawful  for the Bank to maintain or fund any Fixed Rate
         Loans  hereunder,  then the Bank  shall  promptly  notify  Borrower  in
         writing and Borrower shall either repay the  outstanding  Eurodollar or
         CD Loans, as the case may be, owed to the Bank, without penalty, on the
         last  day of the  current  Interest  Periods  (or,  if the Bank may not
         lawfully  continue to maintain  and fund such  Eurodollar  or CD Loans,
         immediately),  or Borrower may convert such  Eurodollar  or CD Loans at
         such appropriate time to Base Rate Loans.

                  (e)  Option to Fund.  The Bank  shall  have the  option if the
         Borrower  elect a Fixed Rate Loan,  to purchase one or more deposits in
         order to fund or maintain its funding of the  principal  balance of the
         Note to which such Fixed Rate Loan is  applicable  during the  Interest
         Period in question;  it being  understood  that the  provisions of this
         Agreement relating to such funding are included only for the purpose of
         determining  the rate of interest to be paid under such Fixed Rate Loan
         and any amounts owing  hereunder and under the Note.  The Bank shall be
         entitled  to fund and  maintain  its funding of all or any part of that
         portion of the principal balance of the Note in any manner it sees fit,
         but all such determinations hereunder shall be made as if the Bank have
         actually funded and maintained that portion of the principal balance of
         the Note to which a Fixed Rate Loan is applicable during the applicable
         Interest  Period through the purchase of deposits in an amount equal to
         the  principal  balance  of the Note to which  such  Fixed Rate Loan is
         applicable and having a maturity corresponding to such Interest Period.
         The Bank may fund the outstanding  principal  balance of the Note which
         is to be  subject  to any Fixed  Rate Loan from any branch or office of
         the Bank as the Bank may designate from time to time.

                  (f) Indemnity.  Borrower shall indemnify and hold harmless the
         Bank  against all  reasonable  and  necessary  out-of-pocket  costs and
         expenses which the Bank may sustain (i) as a consequence of any default
         by Borrower under this Agreement,  or (ii) as a result of the making of
         any loan or loans as a Fixed Rate Loan.

                  (g)  Payments Not at End of Interest  Period.  If the Borrower
         make any payment of  principal  with  respect to any Fixed Rate Loan on
         any day other than the last day of the Interest  Period  applicable  to
         such Fixed Rate Loan,  then Borrower shall reimburse the Bank on demand
         for any loss,  cost or expense  incurred by the Bank as a result of the
         timing  of such  payment  or in  redepositing  such  principal  amount,
         including  the sum of (i) the cost of funds to the Bank in  respect  of
         such principal amount so paid, for the remainder of the Interest Period
         applicable to such sum, reduced,  if the Bank is able to redeposit such
         principal amount so paid for the balance of the Interest Period, by the
         interest earned by Bank as a result of so  redepositing  such principal
         amount,  plus  (ii) any  expense  or  penalty  incurred  by the Bank in
         redepositing such principal amount. A certificate of Bank setting forth
         the basis for the determination of the amount owed by Borrower pursuant
         to this  Section  5(g) shall be  delivered to the Borrower and shall be
         conclusive in the absence of manifest error.

                  (h) Maximum  Number of Loans.  The total number of Loans which
         may be outstanding  at any time hereunder  shall never exceed five (5),
         whether such Loans are Base Rate Loans, CD Loans, Eurodollar Loans or a
         combination thereof.

         6. COLLATERAL SECURITIES.  To secure the performance by Borrower of its
obligations hereunder, and under the Note and Security Instruments,  whether now
or hereafter  incurred,  matured or unmatured,  direct or  contingent,  joint or
several, or joint and several, including extensions, modifications, renewals and
increases thereof, and substitutions therefore,  Borrower has previously granted
and assigned to Bank a first and prior security  interest and Lien on certain of
its  Oil and Gas  Properties,  and on  certain  related  equipment,  oil and gas
inventory and proceeds of the foregoing.  To further  secure the  performance by
Borrower of the aforesaid obligations,  Borrower shall contemporaneously with or
prior to the execution of this  Agreement,  grant and assign to the Bank a first
and  prior  security  interest  and  Lien  on  certain  additional  Oil  and Gas
Properties and on certain additional  related  equipment,  oil and gas inventory
and proceeds of the foregoing.  Obligations arising from agreements arising from
Rate Management  Transactions  between Borrower and the Bank or any Affiliate of
the Bank  providing  for the  hedging,  forward  sale or swap of  crude  oil and
natural gas or interest rate  protection  shall be secured by the Collateral (as
hereinafter defined) on a pari passu basis with the indebtedness and obligations
of the Borrower under the Loan  Documents.  All Oil and Gas Properties and other
collateral in which Borrower has heretofore  granted or hereafter  grants to the
Bank a first and prior Lien (to the satisfaction of the Bank) in accordance with
this  Section  6,  as  such  properties  and  interests  are  from  time to time
constituted, are hereinafter collectively called the "Collateral."


                                     - 18 -

<PAGE>



         The granting  and  assigning of such  security  interests  and Liens by
Borrower  shall be  pursuant  to  Security  Instruments  in form  and  substance
reasonably  satisfactory to the Bank.  Concurrently with the delivery of each of
the Security Instruments,  Borrower shall furnish to the Bank mortgage and title
opinions and other title  information  satisfactory  to Bank with respect to the
title and Lien  status of  Borrower's  interests  in the Oil and Gas  Properties
covered by the Security Instruments as Bank shall have designated. Borrower will
cause to be  executed  and  delivered  to the Bank,  in the  future,  additional
Security  Instruments if the Bank reasonably  deems such are necessary to insure
perfection or maintenance of Bank's security  interests and Liens in the Oil and
Gas Properties or any part thereof.

         7.       BORROWING BASE.

                  (a) Initial  Borrowing  Base.  During the period from the date
         hereof to the first  Determination Date (as hereinafter  defined),  the
         Borrowing Base shall be $38,250,000.00.

                  (b) Subsequent  Determinations  of Borrowing Base.  Subsequent
         determinations of the Borrowing Base shall be made by the Bank at least
         semi-annually  on May 1 and  November 1 of each year  beginning  May 1,
         2000 or as Unscheduled Redeterminations.  The Borrower shall furnish to
         the Bank as soon as possible  but in any event no later than April 1 of
         each year,  beginning  April 1, 2000,  or within thirty (30) days after
         either (i) receipt of notice from Bank that it requires an  Unscheduled
         Redetermination,  or (ii) the  Borrower  give  notice  to Bank of their
         desire  to  have  an  Unscheduled  Redetermination  performed,  with an
         engineering report in form and substance  satisfactory to Bank prepared
         by Borrower and audited by a petroleum  engineering  firm acceptable to
         Bank, valuing the Oil and Gas Properties utilizing economic and pricing
         parameters used by Bank as established from time to time, together with
         such other information, report and data concerning the value of the Oil
         and Gas Properties as Bank shall deem reasonably necessary to determine
         the value of such Oil and Gas  Properties.  Bank shall by notice to the
         Borrower no later than May 1 and  November 1 of each year,  or within a
         reasonable time thereafter  (herein called the  "Determination  Date"),
         designate  a new  Borrowing  Base  for  the  period  beginning  on such
         Determination  Date and continuing  until, but not including,  the next
         Determination  Date. If an Unscheduled  Redetermination  is made by the
         Bank, the Bank shall notify the Borrower within a reasonable time after
         receipt of all requested  information  of the new Borrowing  Base,  and
         such new Borrowing  Base shall  continue  until the next  Determination
         Date. If the Borrower do not furnish all such information,  reports and
         data by the date specified in this Section 7(b), unless such failure is
         of no fault of the  Borrower,  the Bank may  nonetheless  designate the
         Borrowing  Base  at  any  amounts  which  the  Bank  determines  in its
         discretion  and may  redesignate  the Borrowing  Base from time to time
         thereafter  until the Bank receives all such  information,  reports and
         data,  whereupon  the Bank  shall  designate  a new  Borrowing  Base as
         described  above.  The Bank shall determine the amount of the Borrowing
         Base based upon the loan collateral  value which Bank in its discretion
         (using  such  methodology,  assumptions  and  discounts  rates  as Bank
         customarily  uses  in  assigning   collateral  value  to  oil  and  gas
         properties,  oil and gas gathering  systems,  gas  processing and plant
         operations)  assigns to such Oil and Gas  Properties of the Borrower at
         the time in question and

                                     - 19 -

<PAGE>



         based upon such other credit factors  consistently  applied (including,
         without  limitation,  the  assets,  liabilities,  cash flow,  business,
         properties, prospects, management and ownership of the Borrower and its
         affiliates) as Bank customarily considers in evaluating similar oil and
         gas credits. If at any time any of the Oil and Gas Properties are sold,
         the Borrowing Base then in effect shall  automatically  be reduced by a
         sum equal to the loan  collateral  value of the Oil and Gas  Properties
         being sold by  Borrower  which the Bank in its  discretion  (using such
         methodology,  assumptions  and discount  rates as the Bank  customarily
         uses in assigning  collateral value to oil and gas properties) assigned
         to such Oil and Gas Properties at the time in question. It is expressly
         understood  that the Bank has no  obligation to designate the Borrowing
         Base at any  particular  amounts,  except  in the  exercise  of  Bank's
         discretion.  Provided, however, that Bank shall not have the obligation
         to  designate a  Borrowing  Base in an amount in excess of its legal or
         internal lending limits.

         8.       PREPAYMENTS.

                  (a)  Voluntary  Prepayments.  The Borrower may at any time and
         from time to time,  without  penalty or  premium,  prepay the Note,  in
         whole or in part. Each such  prepayment  shall be made on at least five
         (5) Business Days' notice to Bank and shall be in an amount of $500,000
         or more in  increments  of $250,000 or the unpaid  balance on the Note,
         whichever  is  less,  plus  accrued  interest  thereon  to the  date of
         prepayment.  If Borrower  shall prepay the  principal of any CD Loan or
         Eurodollar  Loan on any date  other  than the last day of the  Interest
         Period applicable thereto, Borrower shall make the payments required by
         Section 5(g).

                  (b) Mandatory Prepayment For Borrowing Base Deficiency. In the
         event the  outstanding  principal  balance of the Note ever  exceed the
         Borrowing  Base as  determined by Bank pursuant to Section 7(b) hereof,
         the  Borrower  shall,  within  sixty (60) days  thereof,  either (A) by
         instruments reasonably  satisfactory in form and substance to the Bank,
         provide  the Bank with  collateral  with  value and  quality in amounts
         satisfactory  to the Bank in its  discretion  in order to increase  the
         Borrowing  Base by an  amount  at least  equal to such  excess,  or (B)
         prepay, without premium or penalty, the principal amount of the Note in
         an amount at least equal to such excess plus accrued  interest  thereon
         to the date of prepayment. Each prepayment required to be made pursuant
         to this  Section  8(b) is subject  to the  provisions  of Section  5(g)
         hereof,  provided that, if and to the extent the amount  required to be
         prepaid  hereunder  exceeds the aggregate  principal amount of the Base
         Rate Loans then  outstanding,  Borrower  may,  at its  option,  pay the
         amount of principal of the CD and/or  Eurodollar  Loans  required to be
         prepaid  pursuant to this Section 8(b) to Bank for deposit in a special
         collateral  account to be  established  for this  purpose.  Such amount
         shall  be held by Bank in such  collateral  account  subject  to and in
         accordance  with the  provisions  of this Section 8(b) until the end of
         the  relevant  Interest  Period  or  Periods  for such CD Loans  and/or
         Eurodollar  Loans and  thereupon  applied to the  prepayment of such CD
         Loans and/or Eurodollar  Loans.  Borrower hereby directs Bank to apply,
         and Bank shall apply,  any amounts so deposited in any such  collateral
         account to prepay such CD Loans and/or  Eurodollar  Loans at the end of
         such relevant Interest Period or Periods.

         9. REPRESENTATIONS AND WARRANTIES. In order to induce the Bank to enter
into this  Agreement,  the Borrower  hereby  represents and warrants to the Bank
(which  representations  and  warranties  will survive the delivery of the Note)
that:

                  (a) Creation and  Existence.  Borrower is a  corporation  duly
         organized,  validly existing and in good standing under the laws of the
         jurisdiction  in  which  it was  formed  and is duly  qualified  in all
         jurisdictions  wherein  failure  to  qualify  may  result in a Material
         Adverse  Effect.  Borrower  has  all  power  and  authority  to own its
         properties  and  assets and to  transact  the  business  in which it is
         engaged.

                  (b) Power  and  Authority.  Borrower  is duly  authorized  and
         empowered to create and issue the Note; and Borrower is duly authorized
         and  empowered  to execute,  deliver  and  perform the Loan  Documents,
         including this Agreement;  and all corporate  action on each Borrower's
         part  requisite  for the due  creation and issuance of the Note and for
         the due  execution,  delivery and  performance  of the Loan  Documents,
         including this Agreement, has been duly and effectively taken.


                  (c) Binding Obligations. This Agreement does, and the Note and
         other Loan  Documents  upon their  creation,  issuance,  execution  and
         delivery will,  constitute  valid and binding  obligations of Borrower,
         enforceable  in  accordance  with its  respective  terms  (except  that
         enforcement may be subject to any applicable bankruptcy, insolvency, or
         similar  debtor  relief laws now or hereafter in effect and relating to
         or affecting the enforcement of creditors rights generally).

                  (d) No  Legal  Bar or  Resultant  Lien.  The Note and the Loan
         Documents,  including this Agreement,  do not and will not, violate any
         provisions  of  any  contract,   agreement,  law,  regulation,   order,
         injunction,  judgment,  decree or writ to which Borrower is subject, or
         result in the creation or imposition  of any lien or other  encumbrance
         upon  any  assets  or   properties   of  Borrower,   other  than  those
         contemplated by this Agreement.

                  (e) No Consent. The execution, delivery and performance by the
         Borrower of the Note and the Loan Documents,  including this Agreement,
         does not require the consent or approval of any other person or entity,
         including without  limitation any regulatory  authority or governmental
         body  of the  United  States  or any  state  thereof  or any  political
         subdivision  of the  United  States or any  state  thereof  except  for
         consents  required for federal,  state and, in some instances,  private
         leases,  right of ways and other conveyances or encumbrances of oil and
         gas leases (all of which consents have been obtained by the Borrower).

                  (f) Financial  Condition.  The audited Financial Statements of
         Borrower dated December 31, 1998 and the unaudited Financial Statements
         of Borrower dated September 30, 1999, which have been delivered to Bank
         are  complete  and  correct  in all  material  respects,  and fully and
         accurately reflect in all material respects the financial condition and
         results of the

                                     - 21 -

<PAGE>



         operations  of the  Borrower as of the date or dates and for the period
         or periods  stated.  No change  has since  occurred  in the  condition,
         financial or otherwise, of the Borrower which is reasonably expected to
         have a Material  Adverse  Effect,  except as  disclosed  to the Bank in
         Schedule "2" attached hereto.

                  (g)   Liabilities.   Borrower   does  not  have  any  material
         (individually  or in the  aggregate)  liability,  direct or contingent,
         except as  disclosed  to the Bank in the  Financial  Statements  and on
         Schedule  "3"  attached  hereto.   No  unusual  or  unduly   burdensome
         restrictions,   restraint,   or  hazard  exists  by  contract,  law  or
         governmental  regulation or otherwise relative to the business,  assets
         or  properties  of  Borrower  which is  reasonably  expected  to have a
         Material Adverse Effect.

                  (h)   Litigation.   Except  as  described  in  the   Financial
         Statements,  or as  otherwise  disclosed  to the Bank in  Schedule  "4"
         attached  hereto,  there  is no  litigation,  legal  or  administrative
         proceeding,  investigation or other action of any nature pending or, to
         the  knowledge  of the  officers  of  Borrower  threatened  against  or
         affecting  Borrower which  involves the  possibility of any judgment or
         liability  not fully  covered  by  insurance,  and which is  reasonably
         expected to have a Material Adverse Effect.

                  (i) Taxes;  Governmental  Charges.  Borrower has filed all tax
         returns  and  reports  required  to be filed  and has  paid all  taxes,
         assessments,  fees and other governmental charges levied upon it or its
         assets,  properties  or  income  which are due and  payable,  including
         interest and penalties, the failure of which to pay could reasonably be
         expected to have a Material  Adverse  Effect,  except such as are being
         contested  in good  faith  by  appropriate  proceedings  and for  which
         adequate  reserves for the payment thereof as required by GAAP has been
         provided and levy and  execution  thereon have been stayed and continue
         to be stayed.

                  (j) Titles, Etc. Borrower has good and defensible title to all
         of its respective assets, including without limitation, the Oil and Gas
         Properties,  free and clear of all liens or other  encumbrances  except
         Permitted Liens.

                  (k)  Defaults.  Borrower  is not in  default  and no  event or
         circumstance  has  occurred  which,  but for the passage of time or the
         giving of notice, or both, would constitute a default under any loan or
         credit  agreement,   indenture,   mortgage,  deed  of  trust,  security
         agreement or other agreement or instrument to which Borrower is a party
         in any  respect  that would be  reasonably  expected to have a Material
         Adverse  Effect.  No Event of Default  hereunder  has  occurred  and is
         continuing.

                  (l) Casualties;  Taking of Properties.  Since the dates of the
         latest Financial  Statements of the Borrower delivered to Bank, neither
         the  business  nor the  assets  or  properties  of  Borrower  have been
         affected  (to the  extent it is  reasonably  likely to cause a Material
         Adverse Effect), as a result of any fire, explosion, earthquake, flood,
         drought, windstorm, accident, strike or other labor

         proceeds of the Loan  hereunder  will be used by the  Borrower  for the

         and   Development   Company   ("Questar").   Borrower  is  not  engaged
         principally  or as one of its  important  activities in the business of

         Federal  Reserve  System (12 C.F.R.  Part 221),  or for the  purpose of
         reducing or retiring any indebtedness which was originally  incurred to
         purchase or carry a margin stock or for any other  purpose  which might
         constitute  this  transaction a "purpose  credit" within the meaning of
         said Regulation U.

                  Neither  Borrower nor any person or entity acting on behalf of
         Borrower  has taken or will take any action which might cause the loans
         hereunder or any of the Loan Documents,  including this  Agreement,  to
         violate  Regulation U or any other regulation of the Board of Governors
         of the Federal Reserve System or to violate the Securities Exchange Act
         of 1934 or any rule or  regulation  thereunder,  in each case as now in
         effect or as the same may hereafter be in effect.

                  (n) Location of Business and Offices.  The principal  place of

                    subject; or

                         (ii) has not  failed to  obtain  any  license,  permit,
                    franchise or other governmental  authorization  necessary to

                    conduct of its business;

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

                  (p) No  Material  Misstatements.  No  information,  exhibit or
         report  furnished  by  Borrower  to the  Bank in  connection  with  the
         negotiation of this Agreement  contained any material  misstatement  of
         fact or omitted to state a material fact or any fact  necessary to make
         the statement contained therein not materially misleading.

         requirements of any  Environmental Law or (B) the release or threatened

         (iii) has not received  notice or  otherwise  learned of any federal or
         state investigation evaluating whether any remedial action is needed to
         respond to a release or  threatened  release of any toxic or  hazardous

         instruments;  (iii) setting forth the computation, in reasonable detail

         Default.

                  (d) Taxes and Other Liens. The Borrower will pay and discharge

         Lien or other  encumbrance upon any or all of the assets or property of
         Borrower and which could reasonably be expected to result in a Material
         Adverse Effect; provided,  however, that Borrower shall not be required
         to pay any such tax,  assessment,  charge, levy or claim if the amount,
         applicability or validity thereof shall currently

                                     - 27 -

<PAGE>



         be  contested  in good  faith  by  appropriate  proceedings  diligently
         conducted,  levy and execution thereon have been stayed and continue to
         be stayed and if Borrower shall have set up adequate reserves therefor,
         if required, under GAAP.

                  (e) Compliance with Laws. Borrower will observe and comply, in
         all material respects, with all applicable laws, statutes, codes, acts,
         ordinances,    orders,   judgments,   decrees,   injunctions,    rules,
         regulations,   orders  and   restrictions   relating  to  environmental
         standards or controls or to energy  regulations of all federal,  state,
         county,  municipal  and other  governments,  departments,  commissions,
         boards, agencies, courts, authorities, officials and officers, domestic
         or foreign.

                  (f) Further  Assurances.  The Borrower  will cure promptly any
         defects in the creation and issuance of the Note and the  execution and
         delivery of the Note and the Loan Documents,  including this Agreement.
         The Borrower at its sole expense will  promptly  execute and deliver to
         Bank upon its reasonable  request all such other and further documents,
         agreements and instruments in compliance with or  accomplishment of the
         covenants and agreements in this Agreement, or to correct any omissions
         in the Note or more fully to state the obligations set out herein.

                  (g) Performance of Obligations. The Borrower will pay the Note
         and  other  obligations  incurred  by it  hereunder  according  to  the
         reading,  tenor and effect thereof and hereof; and Borrower will do and
         perform every act and discharge all of the  obligations  provided to be
         performed  and  discharged  by the Borrower  under the Loan  Documents,
         including  this  Agreement,  at the  time or  times  and in the  manner
         specified.

                  (h) Insurance.  The Borrower now maintain and will continue to
         maintain  insurance with financially sound and reputable  insurers with
         respect to its assets  against  such  liabilities,  fires,  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. Upon request of the Bank, the Borrower will furnish
         or cause to be furnished to the Bank from time to time a summary of the
         respective  insurance  coverage of each  Borrower in form and substance
         satisfactory  to the Bank,  and, if  requested,  will  furnish the Bank
         copies of the  applicable  policies.  Upon demand by Bank any insurance
         policies  covering any such  property  shall be endorsed (i) to provide
         that such  policies  may not be  canceled,  reduced or  affected in any
         manner for any reason  without  fifteen (15) days prior notice to Bank,
         (ii) to provide for insurance against fire,  casualty and other hazards
         normally  insured  against,  in the  amount of the full  value  (less a
         reasonable  deductible not to exceed amounts  customary in the industry
         for  similarly  situated  business  and  properties)  of  the  property
         insured,  and (iii) to provide  for such other  matters as the Bank may
         reasonably  require.  The Borrower shall at all times maintain adequate
         insurance  with  respect  to all of  their  assets,  including  but not
         limited to, the Oil and Gas  Properties or any  collateral  against its
         liability for injury to persons or property,  which  insurance shall be
         by  financially   sound  and  reputable   insurers  and  shall  without
         limitation  provide  the  following  coverages:  comprehensive  general
         liability  (including coverage for damage to underground  resources and
         equipment, damage caused by blowouts or

                                     - 28 -

<PAGE>



         cratering,  damage caused by explosion,  damage to underground minerals
         or resources  caused by saline  substances,  broad form property damage
         coverage, broad form coverage for contractually assumed liabilities and
         broad form  coverage  for acts of  independent  contractors),  worker's
         compensation and automobile liability. Additionally, the Borrower shall
         at all times  maintain  adequate  insurance  with respect to all of its
         other assets and wells in accordance with prudent business practices.

                  (i)  Accounts  and  Records.  The  Borrower  will keep  books,
         records and  accounts in which full,  true and correct  entries will be
         made of all  dealings or  transactions  in relation to its business and
         activities,  prepared in a manner consistent with prior years,  subject
         to changes suggested by Borrower's auditors.

                  (j) Right of Inspection. The Borrower will permit any officer,
         employee or agent of the Bank to examine Borrower's books,  records and
         accounts,  and  take  copies  and  extracts  therefrom,   all  at  such
         reasonable  times during normal business hours and as often as the Bank
         may  reasonably  request.  The Bank  will  keep  all  such  information
         confidential  and will not without  prior written  consent  disclose or
         reveal the information or any part thereof to any person other than the
         Bank's officers,  employees,  legal counsel,  regulatory authorities or
         advisors to whom it is  necessary  to reveal such  information  for the
         purpose of  effectuating  the  agreements  and  undertakings  specified
         herein  or as  otherwise  required  by law or in  connection  with  the
         enforcement  of  Bank's  rights  and  remedies  under  the  Note,  this
         Agreement and the other Loan Documents.

                  (k) Notice of Certain  Events.  The  Borrower  shall  promptly
         notify the Bank if Borrower  learns of the  occurrence of (i) any event
         which  constitutes  an  Event  of  Default  together  with  a  detailed
         statement  by  Borrower  of the steps  being taken to cure the Event of
         Default;  or  (ii)  any  legal,  judicial  or  regulatory   proceedings
         affecting  Borrower,  or any of the assets or  properties  of  Borrower
         which, if adversely determined,  could reasonably be expected to have a
         Material Adverse Effect;  or (iii) any dispute between Borrower and any
         governmental or regulatory body or any other person or entity which, if
         adversely determined,  might reasonably be expected to cause a Material
         Adverse Effect; or (iv) any other matter which in Borrower's reasonable
         opinion could have a Material Adverse Effect.

                  (l)  ERISA  Information  and  Compliance.  The  Borrower  will
         promptly  furnish to the Bank  immediately  upon becoming  aware of the
         occurrence  of any  "reportable  event",  as such  term is  defined  in
         Section 4043 of ERISA, or of any "prohibited transaction", as such term
         is defined in Section  4975 of the Internal  Revenue  Code of 1954,  as
         amended, in connection with any Plan or any trust created thereunder, a
         written  notice  signed  or the chief  financial  officer  of  Borrower
         specifying  the  nature  thereof,  what  action  Borrower  is taking or
         proposes to take with  respect  thereto,  and,  when known,  any action
         taken by the Internal Revenue Service with respect thereto.

                  (m)  Environmental  Reports and  Notices.  The  Borrower  will
         deliver to the Bank (i) promptly upon its becoming available,  one copy
         of each report sent by  Borrower to any court,  governmental  agency or
         instrumentality  pursuant to any  Environmental  Law,  (ii) notice,  in
         writing,  promptly  upon  Borrower's  receipt  of notice  or  otherwise
         learning of any claim,  demand,  action,  event,  condition,  report or
         investigation  indicating any potential or actual liability  arising in
         connection  with  (x)  the  non-compliance  with  or  violation  of the
         requirements  of  any  Environmental  Law  which  reasonably  could  be
         expected  to  have a  Material  Adverse  Effect;  (y)  the  release  or
         threatened release of any toxic or hazardous waste into the environment
         which reasonably could be expected to have a Material Adverse Effect or
         which  release  Borrower  would  have a duty to  report to any court or
         government  agency or  instrumentality,  or (iii) the  existence of any
         Environmental  Lien  on any  properties  or  assets  of  Borrower,  and
         Borrower shall immediately deliver a copy of any such notice to Bank.

                  (n) Compliance and Maintenance.  The Borrower will (i) observe
         and comply in all material respects with all  Environmental  Laws; (ii)
         except as provided in Subsections  11(o) and 11(p) below,  maintain the
         Oil and Gas  Properties  and other  assets and  properties  in good and
         workable  condition  at all times and make all  repairs,  replacements,
         additions,  betterments and  improvements to the Oil and Gas Properties
         and other  assets and  properties  as are needed and proper so that the
         business carried on in connection  therewith may be conducted  properly
         and  efficiently at all times in the opinion of the Borrower  exercised
         in good  faith;  (iii) take or cause to be taken  whatever  actions are
         necessary  or  desirable to prevent an event or condition of default by
         Borrower  under the provisions of any gas purchase or sales contract or
         any other contract, agreement or lease comprising a part of the Oil and
         Gas Properties or other  collateral  security  hereunder  which default
         could  reasonably be expected to result in a Material  Adverse  Effect;
         and (iv) furnish Bank upon request  evidence  satisfactory to Bank that
         there  are no  Liens,  claims  or  encumbrances  on  the  Oil  and  Gas
         Properties,  except  laborers',  vendors',   repairmen's,   mechanics',
         worker's,  or  materialmen's  liens  arising  by  operation  of  law or
         incident  to  the  construction  or  improvement  of  property  if  the
         obligations  secured  thereby are not yet due or are being contested in
         good faith by appropriate legal proceedings or Permitted Liens.

                  (o) Operation of Properties.  Except as provided in Subsection
         11(p) and (q) below,  the  Borrower  will  operate,  or use  reasonable
         efforts  to  cause  to be  operated,  all Oil and Gas  Properties  in a
         careful and  efficient  manner in  accordance  with the practice of the
         industry and in compliance in all material respects with all applicable
         laws,  rules,  and  regulations,  and in  compliance  in  all  material
         respects with all  applicable  proration and  conservation  laws of the
         jurisdiction  in which the properties are situated,  and all applicable
         laws, rules, and regulations,  of every other agency and authority from
         time to time  constituted to regulate the  development and operation of
         the properties and the  production and sale of  hydrocarbons  and other
         minerals therefrom; provided, however, that the Borrower shall have the
         right  to  contest  in  good  faith  by  appropriate  proceedings,  the
         applicability or lawfulness of any such law, rule or regulation and

                                     - 30 -

<PAGE>



         pending such contest may defer  compliance  therewith,  as long as such
         deferment  shall not  subject  the  properties  or any part  thereof to
         foreclosure or loss.

                  (p) Compliance with Leases and Other Instruments. The Borrower
         will pay or cause to be paid and discharge all rentals,  delay rentals,
         royalties,  production payment, and indebtedness required to be paid by
         Borrower (or required to keep  unimpaired in all material  respects the
         rights of  Borrower  in Oil and Gas  Properties)  accruing  under,  and
         perform or cause to be  performed  in all  material  respects  each and
         every act, matter, or thing required of Borrower by each and all of the
         assignments, deeds, leases, subleases, contracts, and agreements in any
         way  relating to Borrower or any of the Oil and Gas  Properties  and do
         all other  things  necessary  of  Borrower  to keep  unimpaired  in all
         material respects the rights of Borrower  thereunder and to prevent the
         forfeiture  thereof  or default  thereunder;  provided,  however,  that
         nothing  in this  Agreement  shall be deemed  to  require  Borrower  to
         perpetuate  or renew any oil and gas lease or other lease by payment of
         rental or delay rental or by commencement or continuation of operations
         nor to prevent  Borrower  from  abandoning or releasing any oil and gas
         lease or other lease or well thereon  when,  in any of such events,  in
         the opinion of Borrower  exercised in good faith, it is not in the best
         interest of the Borrower to perpetuate the same.

                  (q) Certain Additional  Assurances  Regarding  Maintenance and
         Operations of Properties.  With respect to those Oil and Gas Properties
         which are being  operated by  operators  other than the  Borrower,  the
         Borrower   shall  not  be   obligated   to  perform  any   undertakings
         contemplated  by the covenants and agreement  contained in  Subsections
         11(o) or 11(p) hereof which are performable  only by such operators and
         are beyond the control of the Borrower; however, the Borrower agrees to
         promptly  take all  reasonable  actions  available  under any operating
         agreements  or  otherwise  to bring about the  performance  of any such
         material undertakings required to be performed thereunder.

                  (r) Title  Matters.  Within  sixty  (60)  days  after the date
         hereof with  respect to the Oil and Gas  Properties  listed on Schedule
         "7",  and,  thereafter,  as to any  Oil and  Gas  Properties  hereafter
         mortgaged to Bank,  Borrower  will  promptly (but in no event more than
         sixty (60) days  following  such  mortgaging),  furnish Bank with title
         opinions  and/or  title  information  reasonably  satisfactory  to Bank
         showing  good  and  defensible  title of  Borrower  to such Oil and Gas
         Properties subject only to Permitted Liens.

                  (s) Curative  Matters.  Within ninety (90) days after the date
         hereof with respect to matters listed on Schedule "8" and,  thereafter,
         within  sixty (60) days  after  receipt  by  Borrower  from Bank or its
         counsel of written notice of title defects the Bank reasonably requires
         to  be  cured,   Borrower   shall  either  (i)  provide  such  curative
         information,  in form  and  substance  satisfactory  to  Bank,  or (ii)
         substitute Oil and Gas Properties of value and quality  satisfactory to
         the  Bank  for all of Oil and  Gas  Properties  for  which  such  title
         curative was requested but upon which  Borrower  elected not to provide
         such title curative information, and, within sixty (60) days of such

                                     - 31 -

<PAGE>



         substitution,  provide title opinions or title information satisfactory
         to the Bank covering the Oil and Gas Properties so substituted.

                  (t) Change of Principal Place of Business. Borrower shall give
         Bank at least thirty (30) days prior written notice of its intention to
         move its  principal  place of  business  from the  address set forth in
         Section 15 hereof.

         12. NEGATIVE COVENANTS. A deviation from the provisions of this Section
12 shall  not  constitute  an Event of  Default  under  this  Agreement  if such
deviation is consented to in writing by Bank.  Without the prior written consent
of Bank,  the Borrower will at all times comply with the covenants  contained in
this Section 12 from the date hereof and for so long as the Term  Commitment  is
in existence or any part of the Term Loan is outstanding.

                  (a)  Negative  Pledge.  Borrower  will not (i) grant,  create,
         incur,  permit or suffer to exist any Lien upon any of its  property or
         assets,  including,  without limitation,  the Collateral,  now owned or
         hereafter  acquired,  except  for  Permitted  Liens and Liens  given to
         secure   Non   Recourse   Debt  of   Borrower,   (ii)  enter  into  any
         sale-and-lease-back  transaction, or (iii) agree with any Person (other
         than in the Loan  Documents)  that  Borrower  will not  grant,  create,
         incur,  permit or suffer to exist any Lien upon any of its  property or
         assets. Anything of the foregoing or elsewhere in the Loan Documents to
         the contrary  notwithstanding,  it is understood  that no Liens,  other
         than  Permitted  Liens,  are permitted on or with respect to any of the
         Collateral.

                  (b) Current  Ratio.  The Borrower  will not allow its ratio of
         Current Assets to Current  Liabilities to be less than 1.0 to 1.0 as of
         the end of any fiscal quarter.

                  (c) Fixed Charge Coverage  Ratio.  Borrower will not allow its
         Fixed Charge Coverage Ratio to ever be less than 1.2 to 1.0.

                  (d) Minimum Net Worth.  The Borrower's Net Worth will not ever
         be less than the sum of (i)  $39,000,000  plus, (ii) after December 31,
         1999,  fifty  percent  (50%) of Net  Income,  if  positive,  plus (iii)
         seventy-five  percent  (75%) of the net  cash  proceeds  of any  equity
         offering.

                  (e) Debt to Worth Ratio.  Borrower will not allow its ratio of
         (i) the aggregate of Total Liabilities to (ii) Net Worth at any time to
         be greater than 1.5 to 1.0.

                  (f) Consolidations and Mergers.  Borrower will not consolidate
         or merge with or into any other Person,  except that Borrower may merge
         with another Person if Borrower is the surviving  entity in such merger
         and if, after  giving  effect  thereto,  no Default or Event of Default
         shall have occurred and be continuing.

                  (g) Debts, Guaranties and Other Obligations. Borrower will not
         incur,  create,  assume or in any manner become or be liable in respect
         of any  indebtedness,  nor will Borrower  guarantee or otherwise in any
         manner become or be liable in respect of any indebtedness,  liabilities
         or  other  obligations  of any  other  Person  or  Entity,  whether  by
         agreement to purchase the indebtedness of any other Person or Entity or
         agreement  for the  furnishing  of funds to any other  Person or Entity
         through the purchase or lease of goods, supplies or services (or by way
         of stock  purchase,  capital  contribution,  advance  or loan)  for the
         purpose of paying or discharging  the  indebtedness of any other Person
         or Entity, or otherwise,  except that the foregoing  restrictions shall
         not apply to:

                         (i) the Note and any  renewal or increase  thereof,  or

                         (ii) taxes,  assessments  or other  government  charges
                    which are not yet due or are being  contested  in good faith
                    by  appropriate  action  promptly  initiated and  diligently
                    conducted,  if such  reserve  as shall be  required  by GAAP
                    shall have been made therefor and levy and execution thereon
                    have been stayed and continue to be stayed; or

                         (iii)  indebtedness  (other than in  connection  with a
                    loan or lending transaction) incurred in the ordinary course
                    of business,  including, but not limited to indebtedness for
                    drilling,  completing,  leasing  and  reworking  oil and gas
                    wells; or

                         (iv) Permitted Purchase Money Indebtedness; or

                         (v) Non-Recourse Debt.

         purchase, redeem or otherwise acquire for value any of its stock now or
         hereafter outstanding,  return any capital to its stockholders, or make
         any  distribution  of its assets to its  stockholders  as such,  except
         Permitted  Dividends  and  Redemptions,   provided,  however,  that  no
         Dividend  or  Redemption  which  would  be  a  Permitted  Dividend  and
         Redemption  may be paid if  immediately  before and after giving effect
         thereto a Default or Event of  Default  shall  exist,  unless and until
         such Dividend or Redemption is consented to by the Bank.

                  (i) Loans and Advances.  Borrower  shall not make or permit to
         remain outstanding any loans or advances to or in any Person or Entity,

         such default shall continue beyond the applicable grace period, if any;
         or

         it or any substantial  part of its property,  and such involuntary case
         or other proceeding shall remain  undismissed and unstayed for a period
         of sixty (60) days;  or an order for  relief  shall be entered  against
         Borrower  under the federal  bankruptcy  laws as now or  hereinafter in

                  (h) A final  judgment  or order  for the  payment  of money in
         excess of $1,000,000  (or judgments or orders  aggregating in excess of

         orders shall continue  unsatisfied  and unstayed for a period of thirty
         (30) days; or

                  (i) In the event the aggregate  principal  amount  outstanding
         under the Note shall at any time exceed the Borrowing Base  established
         for the Note, and the Borrower shall fail to comply with the provisions
         of Section 8(b) hereof; or

         Upon occurrence of any Event of Default  specified in Subsections 13(f)
and (g) hereof,  the entire principal amount due under the Note and all interest
then accrued thereon, and any other liabilities of the Borrower hereunder, shall
become  immediately due and payable all without notice and without  presentment,
demand, protest, notice of protest or dishonor or any other notice of default of
any kind, all of which are hereby expressly waived by the Borrower. In any other
Event of Default, the Bank shall by notice to the Borrower declare the principal
of,  and all  interest  then  accrued  on,  the Note and any  other  liabilities
hereunder to be forthwith due and payable,  whereupon  the same shall  forthwith
become due and payable without presentment, demand, protest, notice of intent to
accelerate, notice of acceleration or other notice of any kind, all of which the
Borrower hereby expressly waive, anything contained herein or in the Note to the
contrary  notwithstanding.  Nothing  contained  in  this  Section  13  shall  be
construed to limit or amend in any way the Events of Default  enumerated  in the
Note,  or any  other  document  executed  in  connection  with  the  transaction
contemplated herein.

         Upon the occurrence and during the continuance of any Event of Default,
the Bank are hereby authorized at any time and from time to time, without notice
to the Borrower (any such notice being

                                     - 36 -

<PAGE>



expressly  waived by the  Borrower),  to set-off and apply any and all  deposits
(general or special, time or demand,  provisional or final) at any time held and
other  indebtedness at any time owing by any of the Bank to or for the credit or
the  account of the  Borrower  against  any and all of the  indebtedness  of the
Borrower  under  the Note  and the Loan  Documents,  including  this  Agreement,
irrespective  of whether  or not the Bank  shall have made any demand  under the
Loan  Documents,  including  this  Agreement  or  the  Note  and  although  such
indebtedness  may be unmatured.  Any amount  set-off by any of the Bank shall be
applied against the indebtedness  owed the Bank by the Borrower pursuant to this
Agreement and the Note.  The Bank agrees  promptly to notify the Borrower  after
any such setoff and  application,  provided that the failure to give such notice
shall not affect the validity of such set-off and application. The rights of the
Bank  under  this  Section  13 are in  addition  to other  rights  and  remedies
(including,  without  limitation,  other  rights of set- off) which the Bank may
have.

         14.  EXERCISE  OF  RIGHTS.  No  failure  to  exercise,  and no delay in
exercising,  on the part of the Bank,  any right  hereunder  shall  operate as a
waiver thereof,  nor shall any single or partial  exercise  thereof preclude any
other or further exercise thereof or the exercise of any other right. The rights
of the Bank hereunder  shall be in addition to all other rights provided by law.
No modification or waiver of any provision of the Loan Documents, including this
Agreement,  or the Note nor consent to departure  therefrom,  shall be effective
unless in  writing,  and no such  consent  or waiver  shall  extend  beyond  the
particular  case and  purpose  involved.  No notice or demand  given in any case
shall constitute a waiver of the right to take other action in the same, similar
or other circumstances without such notice or demand.

         15. NOTICES. Any notices or other communications  required or permitted
to be given by this Agreement or any other documents and instruments referred to
herein must be given in writing  (which may be by  facsimile  transmission)  and
must be personally  delivered or mailed by prepaid  certified or registered mail

is mailed as  aforesaid.  Any party may change its address for  purposes of this
Agreement  by giving  notice of such change to the other party  pursuant to this
Section 15.

         16.  EXPENSES.  The Borrower shall pay (i) all reasonable and necessary
out-of-pocket  expenses of the Bank, including reasonable fees and disbursements
of special  counsel for the Bank, in  connection  with the  preparation  of this
Agreement,  any  waiver or  consent  hereunder  or any  amendment  hereof or any
default or Event of Default  or alleged  default or Event of Default  hereunder,
(ii) all reasonable and necessary  out-of-pocket expenses of the Bank, including
reasonable fees and  disbursements of special counsel for the Bank in connection

participants  requested by the Borrower or any amendment  thereof and (iii) if a

out-of-pocket expenses incurred by the Bank, including fees

                                     - 37 -

<PAGE>



and  disbursements  of counsel,  in  connection  with such  default and Event of
Default and collection and other enforcement  proceedings  resulting  therefrom.
The Borrower  shall  indemnify  the Bank against any  transfer  taxes,  document
taxes,  assessments or charges made by any  governmental  authority by reason of
the execution, delivery and filing of the Loan Documents.

         17.  INDEMNITY.  The Borrower agrees to indemnify and hold harmless the
Bank  and  its   respective   officers,   employees,   agents,   attorneys   and
representatives  (singularly,  an "Indemnified  Party",  and  collectively,  the
"Indemnified  Parties") from and against any loss,  cost,  liability,  damage or
expense (including the reasonable fees and out-of-pocket  expenses of counsel to
the Bank,  including all local counsel hired by such counsel) ("Claim") incurred
by the Bank in investigating or preparing for, defending  against,  or providing
evidence,  producing  documents  or taking  any other  action in  respect of any
commenced or threatened litigation,  administrative  proceeding or investigation
under any federal  securities law,  federal or state  environmental  law, or any
other  statute  of any  jurisdiction,  or any  regulation,  or at common  law or
otherwise, which is alleged to arise out of or is based upon any acts, practices
or  omissions or alleged  acts,  practices or omissions of the Borrower or their
agents or arises in connection  with the duties,  obligations  or performance of
the  Indemnified  Parties  in  negotiating,   preparing,  executing,  accepting,
keeping, completing,  countersigning,  issuing, selling, delivering,  releasing,
assigning,  handling,  certifying,  processing  or receiving or taking any other
action with respect to the Loan Documents and all documents, items and materials
contemplated  thereby even if any of the foregoing  arises out of an Indemnified
Party's ordinary negligence. The indemnity set forth herein shall be in addition
to any other obligations or liabilities of the Borrower to the Bank hereunder or
at common law or otherwise, and shall survive any termination of this Agreement,
the expiration of the Loan and the payment of all  indebtedness  of the Borrower
to the Bank hereunder and under the Note,  provided that the Borrower shall have
no  obligation  under  this  Section  to the  Bank  with  respect  to any of the
foregoing arising out of the gross negligence or willful misconduct of the Bank.
If any Claim is asserted against any Indemnified  Party,  the Indemnified  Party
shall  endeavor to notify the Borrower of such Claim (but failure to do so shall
not affect the  indemnification  herein  made except to the extent of the actual
harm  caused by such  failure).  The  Indemnified  Party shall have the right to
employ, at the Borrower's expense,  counsel of the Indemnified Parties' choosing
and to control the defense of the Claim.  The  Borrower may at their own expense
also participate in the defense of any Claim.  Each Indemnified Party may employ
separate  counsel in  connection  with any Claim to the extent such  Indemnified
Party  believes it reasonably  prudent to protect such  Indemnified  Party.  THE
PARTIES  INTEND FOR THE  PROVISIONS OF THIS SECTION TO APPLY TO AND PROTECT EACH
INDEMNIFIED  PARTY FROM THE  CONSEQUENCES OF ITS OWN NEGLIGENCE,  WHETHER OR NOT
THAT NEGLIGENCE IS THE SOLE, CONTRIBUTING, OR CONCURRING CAUSE OF ANY CLAIM.

         18. GOVERNING LAW. THIS AGREEMENT IS BEING EXECUTED AND DELIVERED,  AND
IS  INTENDED  TO  BE  PERFORMED,  IN  DALLAS,  DALLAS  COUNTY,  TEXAS,  AND  THE
SUBSTANTIVE LAWS OF TEXAS SHALL GOVERN THE VALIDITY,  CONSTRUCTION,  ENFORCEMENT
AND  INTERPRETATION  OF THIS AGREEMENT AND ALL OTHER  DOCUMENTS AND  INSTRUMENTS
REFERRED TO HEREIN, UNLESS OTHERWISE SPECIFIED THEREIN.

                                     - 38 -

         19. INVALID  PROVISIONS.  If any provision of this Agreement is held to
be illegal,  invalid,  or  unenforceable  under present or future laws effective
during the term of this Agreement,  such provisions shall be fully severable and
this  Agreement  shall be construed and enforced as if such illegal,  invalid or
unenforceable  provision had never comprised a part of this  Agreement,  and the
remaining  provisions of the Agreement shall remain in full force and effect and
shall not be affected by the illegal,  invalid or unenforceable  provision or by
its severance from this Agreement.

         20. MAXIMUM  INTEREST RATE.  Regardless of any provisions  contained in
this Agreement or in any other documents and instruments referred to herein, the
Bank shall  never be deemed to have  contracted  for or be  entitled to receive,
collect or apply as  interest  on the Note any  amount in excess of the  Maximum
Rate, and in the event Bank ever  receives,  collects or applies as interest any
such  excess,  of if an  acceleration  of the  maturities  of any Note or if any
prepayment  by the Borrower  result in the Borrower  having paid any interest in
excess of the Maximum Rate, such amount which would be excessive  interest shall
be applied to the  reduction  of the  unpaid  principal  balance of the Note for
which such excess was  received,  collected  or applied,  and, if the  principal
balance of such Note is paid in full,  any remaining  excess shall  forthwith be
paid to the  Borrower.  All sums  paid or  agreed to be paid to the Bank for the
use,  forbearance or detention of the indebtedness  evidenced by the Note and/or
this Agreement  shall, to the extent  permitted by applicable law, be amortized,
prorated,  allocated and spread  throughout  the full term of such  indebtedness
until  payment in full so that the rate or amount of interest on account of such
indebtedness does not exceed the Maximum Rate. In determining whether or not the
interest paid or payable under any specific contingency exceeds the Maximum Rate
of interest  permitted by law,  the Borrower and the Bank shall,  to the maximum
extent  permitted  under  applicable  law, (i)  characterize  any  non-principal
payment as an expense, fee or premium, rather than as interest; and (ii) exclude
voluntary prepayments and the effect thereof; and (iii) compare the total amount
of  interest  contracted  for,  charged  or  received  with the total  amount of
interest  which could be  contracted  for,  charged or received  throughout  the
entire contemplated term of the Note at the Maximum Rate.

         21. AMENDMENTS.  This Agreement may be amended only by an instrument in
writing  executed  by an  authorized  officer  of the  party  against  whom such
amendment is sought to be enforced.

         22. MULTIPLE  COUNTERPARTS.  This Agreement may be executed in a number
of  identical  separate  counterparts,  each of which for all  purposes is to be
deemed  an  original,  but all of  which  shall  constitute,  collectively,  one
agreement.  No party to this Agreement shall be bound hereby until a counterpart
of this Agreement has been executed by all parties hereto.

         23. CONFLICT. In the event any term or provision hereof is inconsistent
with or  conflicts  with any  provision  of the  Loan  Documents,  the  terms or
provisions contained in this Agreement shall be controlling.

         24. SURVIVAL. All covenants, agreements, undertakings,  representations
and warranties made in the Loan Documents, including this Agreement, the Note or
other  documents and  instruments  referred to herein shall survive all closings
hereunder and shall not be affected by any investigation made by any party.

         25.  PARTIES BOUND.  This Agreement  shall be binding upon and inure to
the  benefit of the parties  hereto and their  respective  successors,  assigns,
heirs, legal representatives and estates,  provided,  however, that the Borrower
may not,  without  the prior  written  consent of the Bank,  assign any  rights,
powers, duties or obligations hereunder.

         26. PARTICIPATIONS.  The Bank shall have the right at any time and from
time to time to sell  one or  more  participations  in the  Note or any  Advance
thereunder.  To the  extent of any such  participation  the  provisions  of this
Agreement  shall inure to the  benefit of, and be binding on, each  participant,
including,  but not limited to, any  indemnity  from  Borrower to the Bank.  The
Borrower shall have no obligation or liability to and no obligation to negotiate
or confer with,  any  participant,  and Borrower  shall be entitled to treat the
Bank as the sole owners of the Note without regard to notice or actual knowledge
of any such  participation.  Upon the  occurrence  of a  default  or an Event of
Default,  each  participant  will have and is hereby granted the right to setoff
against and to appropriate and apply from time to time,  without prior notice to
the Borrower or any other party, any such notice being hereby expressly  waived,
any and all deposits (general or special or other indebtedness or claims, direct
or  indirect,  contingent  or  otherwise),  at any  time  held or  owing  by the
participant  to or for the credit or account of Borrower  against the payment of
the note and any other obligations of the Borrower hereunder, provided, however,
none of the rights  granted in this Section 26 shall apply to any deposits  held
by  any  participant   constituting  trust  funds  and  so  identified  to  such
participant at the time the applicable  deposit account is created.  Within five
(5) Business  Days after such setoff or  appropriation  by a  participant,  that
participant  shall give Borrower and Bank written  notice  thereof.  However,  a
failure  to give such  notice  will not affect the  validity  of this  setoff or
appropriation.

         27.      OTHER AGREEMENTS.  THIS WRITTEN LOAN AGREEMENT REPRESENTS THE
FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF
THE PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

         28.  FINANCIAL TERMS. All accounting terms used in this Agreement which
are not specifically defined herein shall be construed in accordance with GAAP.

$38,250,000.00                     Dallas, Texas               November 12, 1999

         FOR VALUE RECEIVED, the undersigned MAYNARD OIL COMPANY, a Delaware
corporation (referred to herein as "Borrower") hereby  unconditionally  promises
to pay to the order of BANK ONE,  TEXAS,  N.A., a national  banking  association
(referred to herein as "Bank"), at its banking offices in Dallas County,  Texas,
the principal sum of THIRTY-EIGHT  MILLION TWO HUNDRED FIFTY THOUSAND AND NO/100
DOLLARS  ($38,250,000.00),  in lawful  money of the  United  States  of  America
together with interest from the date hereof until paid at the rates specified in
the Loan  Agreement  (as  hereinafter  defined).  All payments of principal  and
interest due  hereunder  are payable at the offices of Bank at 1717 Main Street,
4th Floor, TX1-2448,  Dallas, Texas 75201, attention:  Energy Department,  or at
such other address as Bank shall designate in writing to Borrower.

         The principal  and all accrued  interest on this Term Note shall be due
and payable in accordance with the terms and provisions of the Loan Agreement.

         This Term Note is executed  pursuant to that  certain  Second  Restated
Loan Agreement dated of even date herewith  between Borrower and Bank (the "Loan
Agreement"), and is the Term Note referred to therein. This Term Note is secured
by certain Security  Instruments (as such term is defined in the Loan Agreement)
of even date herewith between  Borrower and Bank.  Reference is made to the Loan
Agreement and the Security Instruments for a statement of prepayment, rights and
obligations of Borrower,  description of the properties  mortgaged and assigned,
the nature and extent of such  security and the rights of the parties  under the
Security  Instruments  in respect to such  security  and for a statement  of the
terms  and  conditions  under  which  the  due  date of this  Term  Note  may be
accelerated. Upon the occurrence of an Event of Default, as that term is defined
in the Loan  Agreement  and  Security  Instruments,  the  holder  hereof (i) may
declare  forthwith to be entirely and  immediately due and payable the principal
balance hereof and the interest  accrued hereon,  and (ii) shall have all rights
and remedies of the Bank under the Loan Agreement and Security Instruments. This
Term Note may be prepaid in accordance with the terms and provisions of the Loan
Agreement.

         Regardless  of any  provision  contained in this Term Note,  the holder
hereof shall never be entitled to receive, collect or apply, as interest on this
Term Note,  any amount in excess of the Maximum Rate,  and, if the holder hereof
ever receives,  collects, or applies as interest, any such amount which would be
excessive  interest,  it shall be deemed a partial  prepayment  of principal and
treated hereunder as such; and, if the indebtedness  evidenced hereby is paid in
full, any remaining  excess shall forthwith be paid to Borrower.  In determining
whether or not the interest  paid or payable,  under any  specific  contingency,
exceeds the Maximum Rate,  Borrower and the holder hereof shall,  to the maximum
extent permitted under applicable law (i) characterize any non-principal payment
as an expense,  fee or premium rather than as interest,  (ii) exclude  voluntary
prepayments  and the  effects  thereof,  and (iii)  spread  the total  amount of
interest throughout the entire contemplated term of the obligations evidenced by
this Term Note and/or


<PAGE>



referred  to in the  Loan  Agreement  so  that  the  interest  rate  is  uniform
throughout  the entire term of this Term Note;  provided that, if this Term Note
is paid and  performed  in full prior to the end of the full  contemplated  term
thereof; and if the interest received for the actual period of existence thereof
exceeds the Maximum Rate,  the holder hereof shall refund to Borrower the amount
of such  excess or credit the amount of such  excess  against  the  indebtedness
evidenced hereby,  and, in such event, the holder hereof shall not be subject to
any  penalties  provided  by any laws for  contracting  for,  charging,  taking,
reserving or receiving interest in excess of the Maximum Rate.

         If any payment of  principal or interest on this Term Note shall become
due on a  Saturday,  Sunday or public  holiday or while the Bank is not open for
business,  such payment  shall be made on the next  succeeding  business day and
such  extension of time shall in such case be included in computing  interest in
connection with such payment.

         If this Term Note is placed in the hands of an attorney for collection,
or if it is  collected  through any legal  proceeding  at law or in equity or in
bankruptcy,  receivership or other court proceedings, Borrower agrees to pay all
costs of collection,  including,  but not limited to, court costs and reasonable
attorneys' fees.

         Borrower  and each  surety,  endorser,  guarantor  and other party ever
liable for payment of any sums of money  payable on this Term Note,  jointly and
severally  waive  presentment  and demand for  payment,  notice of  intention to
accelerate the maturity, notice of acceleration of the maturity, protest, notice
of  protest  and  nonpayment,  as to  this  Term  Note  and as to  each  and all
installments  hereof,  and agree that their liability under this Term Note shall
not be affected by any renewal or extension in the time of payment hereof, or in
any indulgences,  or by any release or change in any security for the payment of
this  Term  Note,  and  hereby  consent  to any  and all  renewals,  extensions,
indulgences, releases or changes.

         This Term Note shall be governed by and  construed in  accordance  with
the applicable laws of the United States of America and the laws of the State of
Texas.

         THIS WRITTEN  NOTE,  THE LOAN  AGREEMENT  AND THE OTHER LOAN  DOCUMENTS
REPRESENT THE FINAL  AGREEMENTS  BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED
BY EVIDENCE OF PRIOR,  CONTEMPORANEOUS,  OR  SUBSEQUENT  ORAL  AGREEMENTS OF THE
PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.
