                                    PART I

Item No. 1.  Business
             --------

     Mexco Energy Corporation (the "Registrant"), a Colorado corporation, was
organized in 1972, and maintains its principal office at 214 W. Texas, Suite
1101, Midland, Texas.  Since its incorporation, the Registrant has been engaged
in the acquisition, exploration and development of oil and gas properties
located in the United States.  The bulk of its activities are, and have been
since its incorporation, conducted in the State of Texas.

     The Registrant's corporate name was formerly Miller Oil Company.  In 1980
the shareholders of the Registrant amended the Articles of Incorporation
("Articles") of the Registrant to change the corporate name to Mexco Energy
Corporation.  Also at that time, the shareholders of the Registrant approved
amendments to the Articles resulting in a one-for-fifty reverse stock split of
the Registrant's common stock ($0.50 par value).  The corporate name change and
reverse stock split became effective April 30, 1980.

     The Registrant's operations are not divided into industry segments.  Since
its inception, the Registrant's entire business has been acquiring, and
developing oil and gas properties and producing oil and gas within the oil and
gas industry.  All sales of oil and gas are to unaffiliated customers.  See the
Registrant's financial statements and notes thereto for an account of the
Registrant's past operating results attributable to its oil and gas operations.

     The Registrant acquires interests in producing and non-producing oil and
gas leases purchased from landowners and leaseholders in areas considered
favorable for oil and gas exploration and production by the Registrant.  In
addition, oil and gas prospects are acquired by joining with other oil and gas
operators in drilling prospects which such third parties have generated.  The
Registrant employs a combination of the above methods of obtaining producing
acreage and related prospects.  In recent years, the Registrant has been placing
primary emphasis on evaluation and purchase of producing oil and gas properties.

     As of March 31, 1997, the Registrant held leasehold rights covering in
excess of 193,555 gross acres (3,674 net acres), all of which have producing oil
and gas wells located thereon.  The Registrant is the operator of seven (7) of
the producing wells in which it owns an interest and other companies operate one
thousand five hundred six (1,506) of the remaining producing wells.

     Approximately 81% of the Registrant's present value discounted at ten
percent per annum of future net revenues of total proved reserves is
concentrated in three (3) principal fields, the Lazy JL, Viejos and Gomez
fields. See Note K of the Notes to Financial Statements herein. The Registrant
owns 3,964 gross (1,385 net) acres in the Lazy JL Field located in Garza County,
Texas. The Registrant owns 2,594 gross (191 net) acres in the Viejos Field and

                                       3
<PAGE>
 
9,732 gross (26 net) acres in the Gomez Field both fields located in Pecos
County, Texas.

     The Registrant's oil and gas activities involve oil and gas drilling, which
carries high risk including the risk that no commercial oil or gas production
will be obtained.  The cost of drilling, completing and operating wells is often
uncertain.  Further, drilling may be curtailed or delayed as a result of many
factors, including title problems, weather conditions, delivery delays, and
shortage of pipe and equipment.

     The Registrant is subject to all the risks inherent in the exploration for,
and development and production of, oil and gas, including blowouts, fires, and
other casualties.  The Registrant maintains insurance coverage but losses can
occur from uninsured risks or in amounts in excess of existing insurance
coverage.  The occurrence of an event which is not insured or not fully insured
could have an adverse impact upon the Registrant.

     The oil and gas industry in which the Registrant is engaged is a highly
competitive and speculative business.  Competitors include well-capitalized oil
and gas companies and other companies having financial and other resources
greater than those of the Registrant.  The Registrant's ability to locate and
produce oil and gas reserves is essential to the ultimate realization of income
and value from  the Registrant's properties and, therefore, may be considered to
be a raw material essential to the Registrant's business.  The availability of
drilling rigs, fuel, tubular goods and other drilling and production equipment
is also essential to the Registrant's business.  The Registrant relies on the
acquisition of leases and other oil and gas interests on which to explore for,
develop and/or produce oil and gas.  The availability of such property is
essential to the Registrant's continuing business.

     Crude oil and condensate produced from the properties in which the
Registrant owns an interest are sold to oil companies and pipeline companies at
prices posted by the principal purchasers in the Registrant's producing area.
As of March 31, 1997 the principal purchasers (percentage purchased) of the
Registrant's crude oil production were Navajo Crude Oil Marketing Company (73%)
and Sun Refining and Marketing Company (13%).

     Natural gas obtained from the properties in which the Registrant has an
interest is sold pursuant to contracts negotiated between operators of producing
wells and purchasers of natural gas (subject to the Natural Gas Policy Act).  As
of March 31, 1997 the principal purchasers (percentage purchased) of the
Registrant's natural gas production were approximately:  Aquila Southwest
Pipeline Corporation (60%) and Energy Development Corporation ("EDC") (15%). The
Registrant does not believe that the loss of any of these purchasers would have
a material impact on Registrant's business because of the demand for oil, gas
and casinghead gas production.  Oil and gas production is transported by trucks
and pipelines, respectively.  The Registrant does not own any bulk storage
facilities or pipelines.

                                       4
<PAGE>
 
     As of March 31, 1997, the Registrant employed one full-time and two part-
time persons.  The Registrant believes that relations with these employees are
generally satisfactory.  The Registrant's employees are not covered by
collective bargaining arrangements.

     The Registrant, by nature of its oil and gas operations, is subject to
compliance with federal, state and local provisions regulating the discharge of
materials into the environment or otherwise relating to the protection of the
environment.  At the present time, however, such compliance does not require any
substantial capital expenditures, does not materially affect the Registrant's
earnings and in the Registrant's opinion will not materially affect future
operations.

     The Registrant is not engaged in operations in foreign countries, and no
portion of sales or revenues is derived from customers in foreign countries.

Oil and Gas Reserves
- - --------------------

    See Note K of the Notes to Financial Statements herein for information
regarding the estimated quantities of proved oil and gas reserves owned by the
Registrant.  The oil and gas reserves have been estimated in accordance with
regulations promulgated by the Securities and Exchange Commission.

    The following table indicates estimates by the Registrant's Independent
Petroleum Engineers, T. Scott Hickman & Associates, Inc., of Midland, Texas, of
the availability to the Registrant of proved oil and gas reserves, all of which
are located in the United States, for the years 1996 and 1997.  The estimates
for the year 1995 were prepared by the Registrant's consulting engineer, R.F.
Bailey of Midland, Texas.  For 1997, T. Scott Hickman & Associates, Inc. has
estimated 436,289 barrels of oil and 2,956,219 MCF of gas for a combined
$5,320,610 of future net revenue discounted at ten percent (10%) per annum.
According to SEC guidelines no provisions were made for changes in product
prices and costs; therefore, the Registrant does not believe that these
estimates of reserves and future net revenues fully reflect potential future
revenue values. Estimates of oil and gas reserves are projections based on
engineering information and data.  There are uncertainties inherent in the
interpretation of such data, and there can be no assurance that the reserves set
forth below will be ultimately realized.

</TABLE>

    No major discovery or other favorable or adverse event has caused a material
change in the estimated proved reserves since March 31, 1997 except for the
increase in the Registrant's proved oil and gas reserves as of March 31, 1997
due primarily to purchases and development of producing properties and except
for normal production declines, price and related adjustments.

    The Registrant has not filed any oil or gas reserve estimates or included
any such estimates in reports to any other federal or foreign governmental
authority or agency within the past twelve (12) months.

    The Registrant has no foreign operations and has no agreements with foreign
governments.

    As of March 31, 1997, five (5) wells were to be drilled by the Registrant.
There were no other operations of material importance to Registrant such as
waterfloods and pressure maintenance projects being installed by the Registrant.

Title to Oil and Gas Properties
- - -------------------------------

    Substantially all of the Registrant's properties are currently mortgaged
under a deed of trust to secure funding through a revolving line of credit.  The
Registrant's properties are generally subject to the customary royalty and
overriding royalty interests, liens incident to operating agreements, liens for
current taxes and other burdens and minor encumbrances, easements and
restrictions. The Registrant believes that none of such burdens materially
detract from the value of such properties or materially interferes with their
use in the operation of the Registrant's business.

    As is common industry practice, little or no investigation of title is made
at the time of acquisition of undeveloped properties, other than preliminary
review of local mineral records.  Title investigations, in most cases including
obtaining a title opinion of local counsel, are made before commencement of
drilling operations.  The Registrant believes that its methods of investigating
title to its properties are consistent with practices customary in the oil and
gas industry in connection with the

                                       8
<PAGE>
 
acquisition of such properties, and that such practices are adequately designed
to enable it to acquire good title to such properties.


Undeveloped Acreage
- - -------------------

    The Registrant currently does not own any material inventory of non-
productive acreage in partially developed prospects except those located in the
Viejos Devonian Field of Pecos County, Texas and the Lazy JL Spraberry Field of
Garza County, Texas.  The Registrant owns from 7.29% to 11.57% working interests
(net revenue interests 5.47% to 8.67%) in the Viejos Field of Pecos County,
Texas, consisting of 2,594 gross acres and fifteen (15) wells.

    The Registrant owns from 35% to 40% working interests (net revenue interests
from 26.25% to 30%) in seventeen (17) wells in the Lazy JL (Lower Spraberry)
Field of Garza County, Texas, consisting of 3,964 acres.  The Registrant is
unable to determine the extent of future development, if any, in these two (2)
fields.

Item No. 3.  Legal Proceedings
             -----------------

    The Registrant is not involved in any pending or threatened legal
proceedings except as set forth in Note H of the Notes to Financial Statements
herein.

Item No. 4.  Submission of Matters to a Vote of Security Holders
             ---------------------------------------------------

    No matter has been submitted to a vote of security holders during the fourth
quarter of the fiscal year being reported upon.

Item No. 7.  Management's Discussion and Analysis of Financial
             -------------------------------------------------
             Condition and Results of Operations
             -----------------------------------

Liquidity and Capital Resources and Commitments
- - -----------------------------------------------

     As indicated by the Statements of Cash Flows for the past three fiscal
years, the Registrant has funded its operations, acquisitions, exploration and
development expenditures from cash generated by operating activities, bank
borrowings and issuance of common stock.

     Effective February 25, 1997 the Registrant increased the borrowing base
under its revolving line of credit to $1,750,000.  As of March 31, 1997 the
Registrant had outstanding borrowings thereunder of $1,637,000, leaving $113,000
available to borrow. The line of credit borrowing base reduces $36,500 per month
beginning March 15, 1997, and is reviewed by the bank annually until maturity on
July 15, 1998.  The obligations under the loan agreement are secured by
substantially all of the oil and gas properties of the Registrant and its
subsidiary. The loan agreement contains certain covenants relating to the
financial condition of the Registrant.  The outstanding principal balance bears
interest at the prime rate established by the bank.

     The Registrant also has a letter of credit with NationsBank of Texas, N.A.,
Midland, Texas, which provides for unsecured borrowings up to $50,000 in lieu of
a plugging bond with the Railroad Commission covering properties operated by the
Registrant.

     On May 23, 1997 the Registrant issued 200,000 shares of its common stock
($.50 par value) in a private placement to eleven individuals for $1,000,000. Of
the funds received, $500,000 was used to reduce the principal on the
Registrant's line of credit, $225,000 was used to purchase mineral and royalty
interests in a Gomez Field gas property located in Pecos County, Texas and the
remainder is to be used for the future acquisition and development of oil and
gas properties.

     The Registrant believes that it will have sufficient capital available from
borrowings along with cash flows from operations to fund any future capital
expenditures and to meet its financial obligations.

     In past years, the oil and gas industry from time to time has suffered
because of price decreases for oil.  An oversupply of petroleum in both the
domestic and international markets appeared to be the reason for the price
decline.  The Registrant is unable to predict price changes or the possible
effects on the Registrant at this time.  Past changes in tax laws and the
decline in oil prices have had the effect industry-wide of limiting funds
available for oil and gas exploration.

 Results of Operations
 ---------------------


     Business Segment
     ----------------

     The Registrant only has a single line of business which is oil and gas
acquisition, exploration and production.


     Fiscal 1997 Compared to Fiscal 1996
     -----------------------------------

     Registrant participated in the drilling of twelve (12) gross (2.717 net)
wells, of which nine (9) were productive oil wells in fiscal 1997 and one well
which is currently shut-in pending plans to convert to a water injection well.

     A decrease in working capital of $124,050 for fiscal 1997, compared to an
increase of $20,300 for fiscal 1996 was the result of increased acquisition,
drilling and development costs.
 
     Gross revenue from oil and gas production increased in 1997 compared to
1996 by $654,535 (82%) and the Registrant reflected net earnings of $377,867
which is an increase of $177,261 (88%).  Revenues increased due to the increase
in oil and gas production from acquisition and development of oil and gas
properties and the increase in oil and gas prices during the current year. The
average 1997 price for crude oil is $22.09 per barrel compared to the 1996 price
of $17.45.  Average prices received per MCF of gas for 1997 and 1996 were $2.47
and $1.57, respectively.

     Administrative services income and reimbursement to the Registrant
decreased $2,371 (32%) due to the plugging and abandonment of two operated wells
during the prior year.

     Production costs increased $73,873 (27%) from 1996. Of this increase,
$37,897 is attributable to increased production taxes relating to the increase
in production and revenues as stated above with the remaining $35,976 being
attributable to increased operating expenses due to the acquisition and
development of new wells in 1997. Production costs per barrel equivalent
actually declined by 3%.

     Interest income decreased $10,120 (59%) due to the reduced funds invested
in a money market account.

     Other income of $608 in 1997 consisted of reimbursed expenses.

     Overall, costs and expenses increased in 1997 by $328,637
(53%).  Depreciation, depletion and amortization increased in 1997 as compared
to 1996 by $215,438 (82%) due to increased production, acquisition and
development of oil and gas properties.  General and administrative expenses
increased $26,539 (31%) primarily due to increased salaries, legal fees,
accounting fees and engineering costs.

     Fiscal 1996 Compared to Fiscal 1995
     -----------------------------------

     Registrant participated in the drilling of nine (9) gross (.815 net) wells,
of which seven (7) were productive oil wells in fiscal 1996.

     An increase in working capital of $20,300 for fiscal 1996, compared to a
decrease of $466,825 for fiscal 1995 was a result of increased receipts of oil
and gas sales and proceeds of a private placement of the Registrant's common
stock.

     Gross revenue from oil and gas production increased in 1996 compared to
1995 by $255,322 (47%) and the Registrant reflected net earnings of $200,606.
Revenues increased due to the increase in oil and gas production from
acquisition and development of oil and gas properties.  This increase was
affected by increase in revenues from sales of crude oil and natural gas during
the current period.  The average 1996 price for crude oil was $17.45 per barrel
compared to the 1995 price of $16.40.  Average prices paid per MCF of gas for
1996 and 1995 were $1.57 and $1.32, respectively.

     Administrative services income and reimbursement to the Registrant
decreased $2,743 (27%) due to the plugging and abandonment of certain wells
during the current year.

     Production costs increased $65,263 (31%) from 1995 primarily from the
addition of new wells drilled in 1996.

     Other income in 1996 consisted primarily of $17,285 of interest income from
investment in a liquid asset money market fund and $6,979 of gas gathering fees
from the Viejos field.

     Overall, costs and expenses increased in 1996 by $162,672 (36%).  Normal
depreciation, depletion and amortization increased in 1996 as compared to 1995
by $91,669 (54%) due to increased  acquisition, development and production of
properties.  General and administrative expenses increased $5,740 (7%).

Board of Directors
Mexco Energy Corporation

We have audited the accompanying consolidated balance sheets of Mexco Energy
Corporation and Subsidiary, as of March 31, 1997 and 1996, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
each of the three years in the period ended March 31, 1997.  These financial
statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Mexco Energy
Corporation and Subsidiary, as of March 31, 1997 and 1996, and the consolidated
results of their operations and their consolidated cash flows for each of the
three years in the period ended March 31, 1997 in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                         March 31, 1997, 1996, and 1995


  NOTE A - NATURE OF OPERATIONS AND SUMMARY OF ACCOUNTING POLICIES

       The major operations of Mexco Energy Corporation and subsidiary, (the
   "Company") consist of exploration, production, and sale of crude oil and
   natural gas in the United States with an area of concentration in Texas.

       A summary of the significant accounting policies consistently applied in
   the preparation of the accompanying financial statements follows.

        1.  Principles of Consolidation
            ---------------------------

        The Company consolidates the accounts of its wholly-owned subsidiary,
   Forman Energy Corporation ("Forman"), eliminating all intercompany balances
   and transactions.

        2.  Oil and Gas Properties
            ----------------------

       The full cost method of accounting is used to account for oil and gas
   properties.  Under this method of accounting, all costs incident to the
   acquisition, exploration, and development of properties (both developed and
   undeveloped), including costs of abandoned leaseholds, lease rentals,
   unproductive wells, and well drilling and equipment costs, are capitalized.
   Costs are amortized using the units-of-production method based primarily on
   estimates of reserve quantities.  Due to uncertainties inherent in this
   estimation process, it is at least reasonably possible that reserve
   quantities will be revised significantly in the near term.  If the Company's
   unamortized costs exceed the cost center ceiling (defined as the sum of the
   present value, discounted at 10%, of estimated unescalated future net
   revenues from proved reserves, less related income tax effects), the excess
   is charged to expense in the year in which the excess occurs.  Generally, no
   gains or losses are recognized on the sale or disposition of oil and gas
   properties.

        3.  Depreciation
            ------------

       Depreciation of office furniture, fixtures, and equipment is provided on
   the straight-line method over estimated useful lives of three to ten years.

        4.  Production Costs and Administrative Service Arrangements
            --------------------------------------------------------

       Production costs include lease operating expenses and production taxes.
   Reimbursements related to administrative service arrangements are recorded as
   revenues.

        5.  Earnings Per Share
            ------------------

       Earnings per share is calculated using the weighted average number of
   shares outstanding during each year.

        6.  Cash and Cash Equivalents
            -------------------------

       The Company considers all highly liquid debt instruments purchased with a
   maturity of three months or less and money market funds to be cash
   equivalents.

       The Company maintains its cash in bank deposit accounts and money market
   funds, some of which are not federally insured.  The Company has not
   experienced any losses in such accounts and believes it is not exposed to any
   significant credit risk.

  NOTE A - NATURE OF OPERATIONS AND SUMMARY OF ACCOUNTING POLICIES - CONTINUED

    7.  Income Taxes
        ------------

    The Company accounts for income taxes using the liability method. Under the
  liability method of accounting for income taxes, deferred taxes are recognized
  for the tax consequences of temporary differences by applying enacted tax
  rates applicable to future years to differences between the carrying amounts
  and the tax bases of existing assets and liabilities.

    8.  Use of Estimates
        ----------------

    In preparing financial statements in conformity with generally accepted
  accounting principles, management makes estimates based on management's
  knowledge and experience. Due to their prospective nature, actual results
  could differ from those estimates.

  NOTE B - BUSINESS COMBINATION

    On February 25, 1997, Mexco acquired Forman who is engaged in the
  exploration, production and sale of crude oil and natural gas.  The
  acquisition has been accounted for using the purchase method, and the
  operations of the acquired company are included subsequent to February 1,
  1997.  The purchase price of approximately $1,591,000 was allocated to the
  assets, primarily oil and gas properties, acquired on the basis of their
  estimated fair value.

    The following summarized pro forma, unaudited, information assumes the
  acquisition of Forman had occurred on April 1, 1995:

</TABLE>

  NOTE C - BANK LINE OF CREDIT

    The Company has a $1,750,000 revolving line of credit with NationsBank of
  Texas, N.A. at March 31, 1997.  The borrowing base of the line is reduced by
  $36,500 each month throughout the term of the loan.  At March 31, 1997, the
  borrowing base is $1,713,500.  The line of credit may be drawn down through
  July 15, 1998.  There are no required principal payments in the next fiscal
  year based on the current level of debt and a principal payment made
  subsequent to March 31, 1997.  The subsequent principal payment was made from
  proceeds of a stock offering subsequent to March 31, 1997 (Note J) and
  therefore is not reflected as a current liability.  Interest is payable
  monthly at prime rate as established by the bank.  The line of credit is
  collateralized by the common stock of Forman and oil and gas properties.

       As of March 31, 1997, the Company has statutory depletion carryforwards
   of approximately $376,000 which do not expire.

  NOTE E - SEGMENT INFORMATION AND MAJOR CUSTOMERS

       The Company operates exclusively within the United States in the onshore
   exploration and production of oil and gas.  In the normal course of business,
   the Company extends credit to customers in the oil and gas industry and
   therefore has significant credit risk in this sector of the economy.
   Historically, the Company has not had significant bad debts and, as such, no
   allowance for doubtful accounts has been provided in the accompanying
   financial statements.

   Customers which accounted for 10% or more of revenues are as follows:

  NOTE G - RELATED PARTY TRANSACTIONS

       The Company serves as operator of properties in which the majority
   stockholder has interests and, in that capacity, bills the majority
   stockholder for lease operating expenses on a monthly basis subject to usual
   trade terms.  The billings totaled approximately $112,657, $106,198, and
   $152,597 for the years ended March 31, 1997, 1996, and 1995, respectively.
   Accounts receivable include $6,042 and $12,297 due from the majority
   stockholder at March 31, 1997 and 1996, respectively.

  NOTE H - LITIGATION

       The Company was one of several plaintiffs in a lawsuit for damages in
   connection with a gas contract. During 1997, the suit was settled without any
   effect on the Company.

       The Company is subject to certain legal proceedings and claims which have
   arisen in the ordinary course of its business which management believes will
   not result in any material liability.

  NOTE I - FINANCIAL INSTRUMENTS

       The following table includes estimated fair value information as of March
   31, 1997 and 1996, as required by Financial Accounting Standards Board
   Statement No. 107.  Such information, which pertains to the Company's
   financial instruments, is based on the requirements set forth in that
   Statement and does not purport to represent the aggregate net fair value of
   the Company.  All of the financial instruments are held for purposes other
   than trading.

       The following methods and assumptions were used to estimate the fair
   value of each class of financial instruments for which it is practicable to
   estimate that value.

       Cash and Cash Equivalents - The carrying amount approximates fair value
       -------------------------                                              
   because of the contractual right to receive the deposits upon demand.

       Bank Line of Credit - The carrying amount approximates fair value because
       -------------------                                                      
  floating interest rates approximate current market rates.

    Financial instruments and the estimated fair values are as follows:

  NOTE J - SUBSEQUENT EVENT

    On May 23, 1997, the Company issued 200,000 shares of common stock for $5.00
   per share through a private placement.

  NOTE K - OIL AND GAS RESERVE DATA (UNAUDITED)

       In accordance with Statement of Financial Accounting Standards No. 69
   (SFAS 69) and Securities and Exchange Commission (SEC) rules and regulations,
   the following information is presented with regard to the Company's proved
   oil and gas reserves, all of which are located in the United States.
   Information for oil is presented in barrels (Bbls) and for gas in thousand
   cubic feet (Mcf).

       The SEC has adopted SFAS 69 disclosure guidelines for oil and gas
   producers.  These rules require the Company to include as a supplement to the
   basic financial statements a standardized measure of discounted future net
   cash flows relating to proved oil and gas reserves.

       The standardized measure, in management's opinion, should be examined
   with caution.  The basis for these disclosures is an independent petroleum
   engineer's reserve study which contains imprecise estimates of quantities and
   rates of production of reserves.  Revision of prior year estimates can have a
   significant impact on the results.  Also, exploration costs in one year may
   lead to significant discoveries in later years and may significantly change
   previous estimates of proved reserves and their valuation. Values of unproved
   properties and anticipated future price and cost increases or decreases are
   not considered.  Therefore, the standardized measure is not necessarily a
   "best estimate" of the fair value of the Company's oil and gas properties or
   of future net cash flows.

       The following summaries of changes in reserves and standardized measure
   of discounted future net cash flows were prepared from estimates of proved
   reserves developed by independent petroleum engineers.

     2.   LOANS.
          ----- 

          A.   LOAN. Bank hereby agrees to make one or more loans to Borrowers
in the aggregate principal face amount of $1,750,000.00. The obligation to repay
the loans is evidenced by a promissory note dated of even date herewith (the
promissory note together with any and all renewals, extensions or rearrangements
thereof being hereafter collectively referred to as the "Note") having a
maturity date, repayment terms and interest rate as set forth in the Note. The
Note is in renewal, extension and rearrangement, but not in extinguishment or
novation, of that certain promissory note dated August 9, 1996, in the original
principal amount of $500,000.00, executed by Mexco and payable to the order of
Bank.

               i.       REVOLVING CREDIT FEATURE. The Loan provides for a
          revolving line of credit (the "Line") under which Borrowers may from
          time to time, borrow, repay and re-borrow funds. The funds borrowed
          under the Line shall never exceed at any one time outstanding the
          lesser of (a) $1,750,000.00, or (b) the Borrowing Base from time to
          time in effect.

               ii.      BORROWING BASE. The Line is subject to the following
Borrowing Base agreement: the Borrowing Base is the amount of the loan value
which Bank assigns, in the exercise of its sole discretion, to the collateral
pledged by Borrowers to Bank under the Deed of Trust (defined below). The
Borrowing Base is initially set at the amount of $1,750,000.00, but shall
automatically reduce by the sum of $36,500.00 on the 15th day of each month,
beginning March 15, 1997, and continue on the 15th day of each month thereafter
during the term of the Note. In the event that the unpaid principal balance of
the Note shall be in excess of the Borrowing Base on the date of any such
automatic Borrowing Base reduction, Borrowers shall pay such excess to Bank, in
addition to the payment of accrued interest due, on such date. Further, the
Borrowing Base shall be redetermined on an annual basis, on or about January 15
of each year, or at any time that it appears to Bank, in its sole discretion,
that there has been a material change in the value of the collateral securing
the Note. In the event that the unpaid principal of the Note shall, at any time,
be in excess of the Borrowing Base as a result of the annual or any
discretionary Borrowing Base redetermination made by Bank hereunder (but not as
a result of an automatic Borrowing Base reduction as provided for above),
Borrowers shall, within fifteen (15) days thereafter (a) by instruments
satisfactory in form and substance to Bank, provide Bank with additional
collateral with value in amounts satisfactory to Bank in order to increase the
Borrowing Base by an amount at least equal to such excess, or (b) prepay the
principal of the Note in an amount at least equal to such excess. As used
herein, the term "Deed of Trust" shall mean that certain Deed of Trust,
Mortgage, Assignment, Security Agreement and Financing Statement of even date
herewith executed by Mexco to Michael F. Hord, as Trustee for the benefit of
Lender, as such Deed of Trust may hereafter be amended, modified, supplemented,
renewed and/or extended.

     3.   REPRESENTATIONS AND WARRANTIES. Borrowers hereby jointly and severally

FOR VALUE RECEIVED, the undersigned Borrower unconditionally (and jointly and
severally, if more than one) promises to pay to the order of Bank, its
successors and assigns, without setoff, at its offices indicated at the
beginning of this Note, or at such other place as may be designated by Bank, the
principal amount of ONE MILLION SEVEN HUNDRED FIFTY THOUSAND AND NO/100 DOLLARS
($1,750,000.00), or so much thereof as may be advanced from time to time in
immediately available funds, together with interest computed daily on the
outstanding principal balance hereunder, at an annual interest rate, and in
accordance with the payment schedule, indicated below.

[THIS NOTE CONTAINS SOME PROVISIONS PRECEDED BY BOXES. IF A BOX IS MARKED, THE
PROVISION APPLIES TO THIS TRANSACTION; IF IT IS NOT MARKED, THE PROVISION DOES
NOT APPLY TO THIS TRANSACTION.]

1.  RATE.

[X] PRIME RATE. The Rate shall be the Prime Rate, plus  0.00, per annum. The
                                                        ----                
"Prime Rate" is the fluctuating rate of interest established by Bank from time
to time, at its discretion, whether or not such rate shall be otherwise
published. The Prime Rate is established by Bank as an index and may or may not
at any time be the best or lowest rate charged by Bank on any loan.

[_] FIXED RATE. The Rate shall be fixed at ______________________ percent per
annum.

[_] OTHER.______________________________________________________________________
________________________________________________________________________________

Notwithstanding any provision of this Note, Bank does not intend to charge and
Borrower shall not be required to pay any amount of interest or other charges in
excess of the maximum permitted by applicable law. Borrower agrees that during
the full term hereof, the maximum lawful interest rate for this Note as
determined under Texas law shall be the indicated rate ceiling as specified in
Article 5069-1.04 of VATS. Further, to the extent that any other lawful rate
ceiling exceeds the rate ceiling so determined then the higher rate ceiling
shall apply. Any payment in excess of such maximum shall be refunded to Borrower
or credited against principal, at the option of Bank.

2. ACCRUAL METHOD. Unless otherwise indicated, interest at the Rate set forth
above will be calculated by the 365/360 day method (a daily amount of interest
is computed for a hypothetical year of 360 days; that amount is multiplied by
the actual number of days for which any principal is outstanding hereunder). If
interest is not to be computed using this method, the method shall
be:____________________________________________________________________________
_______________________________________________________________________________ 
_______________________________________________________________________________.

3. RATE CHANGE DATE.  Any Rate based on a fluctuating index or base rate will
change, unless otherwise provided, each time and as of the date that the index
or base rate changes. If the Rate is to change on any other date or at any other
interval, the change shall be:_________________________________________________ 
_______________________________________________________________________________.
In the event any index is discontinued, Bank shall substitute an index
determined by Bank to be comparable, in its sole discretion.

4. PAYMENT SCHEDULE. All payments received hereunder shall be applied first to
the payment of any expense or charges payable hereunder or under any other loan
documents executed in connection with this Note, then to interest due and
payable, with the balance applied to principal, or in such other order as Bank
shall determine at its option.

[_] PRINCIPAL PLUS ACCRUED INTEREST. Principal shall be paid in consecutive
equal installments of $_____________________,plus accrued interest, payable [_]
monthly,  [_] quarterly or commencing on __________, 19__, and continuing on 
the [_] same day, [_] last day of each successive month, quarter or other 
period (as applicable) thereafter, with a final payment of all unpaid principal
and accrued interest due on ____________, 19__.

[_] FIXED PRINCIPAL AND INTEREST.  Principal and interest shall be paid in
consecutive equal installments of $___________________, payable [_] monthly, [_]
quarterly or [_]____________________________, commencing on _____________,19__,
and continuing on the [_] same day, [_] last day of each successive month, 
quarter or other period (as applicable) thereafter, with a final payment of all 
unpaid principal and interest due thereon on _____________,19__. If, on any 
payment date, accrued interest exceeds the installment amount set forth above, 
Borrower will also pay such excess as and when billed.

payment on  July l5,1998.  Interest thereon shall be paid [_] at maturity, or
            -------------

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

5.  REVOLVING FEATURE.

[X]  Borrower may borrow, repay and reborrow hereunder at any time, up to a
maximum aggregate amount outstanding at any one time equal to the principal
amount of this Note, provided that Borrower is not in default under any
provision of this Note, any other documents executed in connection with this
Note, or any other note or other loan documents now or hereafter executed in
connection with any other obligation of Borrower to Bank, and provided that the
borrowings hereunder do not exceed any borrowing base or other limitation on
borrowings by Borrower. Bank shall incur no liability for its refusal to advance
funds based upon its determination that any conditions of such further advances
have not been met. Bank records of the amounts borrowed from time to time shall
be conclusive proof thereof.

   [_]  UNCOMMITTED FACILITY. Borrower acknowledges and agrees that,
notwithstanding any provisions of this Note or any other documents executed in
connection with this Note, Bank has no obligation to make any advance, and that
all advances are at the sole discretion of Bank.

   [_]  OUT-OF-DEBT PERIOD. For a period of at least _____________________
consecutive days during [_] each fiscal year, [_] any consecutive 12-month
period, Borrower shall fully pay down the balance of this Note, so that no
amount of principal or interest and no other obligation under this Note remains
outstanding.

6.  AUTOMATIC PAYMENT.

[_] Borrower has elected to authorize Bank to effect payment of sums due under
this Note by means of debiting Borrower's account number ____________________. 
This authorization shall not affect the obligation of Borrower to pay such sums
when due, without notice, if there are insufficient funds in such account to
make such payment in full on the due date thereof, or if Bank fails to debit the
account.

7.  WAIVERS, CONSENTS AND COVENANTS.  Borrower, any indorser or guarantor
hereof, or any other party hereto (individually an "Obligor" and collectively
"Obligors") and each of them jointly and severally: (a) waive presentment,
demand, protest, notice of demand, notice of intent to accelerate, notice of
acceleration of maturity, notice of protest, notice of nonpayment, notice of
dishonor, and any other notice required to be given under the law to any Obligor
in connection with the delivery, acceptance, performance, default or enforcement
of this Note, any indorsement or guaranty of this Note, or any other documents
executed in connection with this Note or any other note or other loan documents
now or hereafter executed in connection with any obligation of Borrower to Bank
(the "Loan Documents"); (b) consent to all delays, extensions, renewals or other
modifications of this Note or the Loan Documents, or waivers of any term hereof
or of the Loan Documents, or release or discharge by Bank of any of Obligors, or
release, substitution or exchange of any security for the payment hereof, or the
failure to act on the part of Bank, or any indulgence shown by Bank (without
notice to or further assent from any of Obligors), and agree that no such
action, failure to act or failure to exercise any right or remedy by Bank shall
in any way affect or impair the obligations of any Obligors or be construed as a
waiver by Bank of, or otherwise affect, any of Bank's rights under this Note,
under any indorsement or guaranty of this Note or under any of the Loan
Documents; and (c) agree to pay, on demand, all costs and expenses of collection
or defense of this Note or of any indorsement or guaranty hereof and/or the
enforcement or defense of Bank's rights with respect to, or the administration,
supervision, preservation, or protection of, or realization upon, any property
securing payment hereof, including, without limitation, reasonable attorney's
fees, including fees related to any suit, mediation or arbitration proceeding,
out of court payment agreement, trial, appeal, bankruptcy proceedings or other
proceeding, in such amount as may be determined reasonable by any arbitrator or
court, whichever is applicable.

8.  PREPAYMENTS. Prepayments may be made in whole or in part at any time on any
loan for which the Rate is based on the Prime Rate. All prepayments of principal
shall be applied in the inverse order of maturity, or in such other order as
Bank shall determine in its sole discretion. No prepayment of any other loan
shall be permitted without the prior written consent of Bank. Notwithstanding
such prohibition, if there is a prepayment of any such loan, whether by consent
of Bank, or because of acceleration or otherwise, Borrower shall, within 15 days
of any request by Bank, pay to Bank any loss or expense which Bank may incur or
sustain as a result of such prepayment. For the purposes of calculating the
amounts owed only, it shall be assumed that Bank actually funded or committed to
fund the loan through the purchase of an underlying deposit in an amount and for
a term comparable to the loan, and such determination by Bank shall be
conclusive, absent a manifest error in computation.

9.  EVENTS OF DEFAULT. The following are events of default hereunder: (a) the
failure to pay or perform any obligation, liability or indebtedness of any
Obligor to Bank, or to any affiliate or subsidiary of NationsBank Corporation,
whether under this Note or any Loan Documents, as and when due (whether upon
demand, at maturity or by acceleration); (b) the failure to pay or perform any
other obligation, liability or indebtedness of any Obligor to any other party;
(c) the death of any Obligor (if an individual); (d) the resignation or
withdrawal of any partner or a material owner/guarantor of Borrower, as
determined by Bank in its sole discretion; (e) the commencement of a proceeding
against any Obligor for dissolution or liquidation, the voluntary or involuntary
termination or dissolution of any Obligor or the merger or consolidation of any
Obligor with or into another entity; (f) the insolvency of, the business
failure of, the appointment of a custodian, trustee, liquidator or receiver for
or for any of the property of, the assignment for the benefit of creditors by,
or the filing of a petition under bankruptcy, insolvency or debtor's relief law
or the filing of a petition for any adjustment of indebtedness, composition or
extension by or against any Obligor; (g) the determination by Bank that any
representation or warranty made to Bank by any Obligor in any Loan Documents or
otherwise is or was, when it was made, untrue or materially misleading; (h) the
failure of any Obligor to timely deliver such financial statements, including
tax returns, other statements of condition or other information, as Bank shall
request from time to time; (i) the entry of a judgment against any Obligor which
Bank deems to be of a material nature, in Bank's sole discretion; (j) the
seizure or forfeiture of, or the issuance of any writ of possession, garnishment
or attachment, or any turnover order for any property of any Obligor; (k) the
determination by Bank that it is insecure for any reason; (l) the determination
by Bank that a material adverse change has occurred in the financial condition
of any Obligor; or (m) the failure of Borrower's business to comply with any law
or regulation controlling its operation.

10.  REMEDIES UPON DEFAULT. Whenever there is a default under this Notice (a) 
the entire balance outstanding hereunder and all other obligations oXXXXXXy
Obligor to Bank (however acquired or enhanced) shall, at the option of Bank,
become immediately due and payable and any obligation of Bank to permit further
borrowing under this Note shall immediately cease and terminate, and/or (b) to
the extent permitted by law, the Rate of interest on the unpaid principal shall
be increased at Bank's discretion up to the maximum rate allowed by law, or if
none, 25% per annum (the "Default Rate"). The provisions herein for a Default
Rate shall not be deemed to extend the time for any payment hereunder or to
constitute a "grace period" giving Obligors a right to cure any default. At
Bank's option, any accrued and unpaid interest, fees or charges may, for
purposes of computing and accruing interest on a daily basis after the due date
of the Note or any installment thereof, be deemed to be a part of the principal
balance, and interest shall accrue on a daily compounded basis after such date
at the Default Rate provided in this Note until the entire outstanding balance
of principal and interest is paid in full. Upon a default under this Note, Bank
is hereby authorized at any time, at its option and without notice or demand, to
set off and charge against any deposit accounts of any Obligor (as well as any
money, instruments, securities, documents, chattel paper, credits, claims,
demands, income and any other property, rights and interests of any Obligor),
which at any time shall come into the possession or custody or under the control
of Bank or any of its agents, affiliates or correspondents, any and all
obligations due hereunder. Additionally, Bank shall have all rights and remedies
available under each of the Loan Documents, as well as all rights and remedies
available at law or in equity.

11.  NON-WAIVER. The failure at any time of Bank to exercise any of its options
or any other rights hereunder shall not constitute a waiver thereof, nor shall
it be a bar to the exercise of any of its options or rights at a later date. All
rights and remedies of Bank shall be cumulative and may be pursued singly,
successively or together, at the option of Bank. The acceptance by Bank of any
partial payment shall not constitute a waiver of any default or of any of Bank's
rights under this Note. No waiver of any of its rights hereunder, and no
modification or amendment of this Note, shall be deemed to be made by Bank
unless the same shall be in writing, duly signed on behalf of Bank; each such
waiver shall apply only with respect to the specific instance involved, and
shall in no way impair the rights of Bank or the obligations of Obligors to Bank
in any other respect at any other time.

12.  APPLICABLE LAW, VENUE AND JURISDICTION. Borrower agrees that this Note

follows:

   A.  FINANCING STATEMENTS. Except as may be noted by schedule attached hereto
and incorporated herein by reference, no financing statement covering the

statements relating to this security interest, and no security interest, other
than the one herein created, has attached or been perfected in the Collateral or
any part thereof.

   B.  OWNERSHIP. Pledgor owns, or will use the proceeds of any loans by Bank to
become the owner of, the Collateral free from any setoff, claim, restriction,
lien, security interest or encumbrance except liens for taxes not yet due and
payable and the security interest hereunder.

Agreement, and all necessary consents and approvals of any persons, entities,

Collateral, including but not limited to taxes, assessments, reasonable
attorney's fees, legal expenses and expenses of sales. Whether the Collateral is
or is not in Bank's possession, and without any obligation to do so and without
waiving Pledgor's default for failure to make any such payment, Bank at its
option may pay any such costs and expenses and discharge encumbrances on the
Collateral, and such payments shall be a part of the Obligation and bear
interest at the rate set out in the Obligation. Pledgor agrees to reimburse Bank
on demand for any costs so incurred.

   D.  INFORMATION AND INSPECTION. Pledgor shall (i) promptly furnish Bank any
information with respect to the Collateral requested by Bank; (ii) allow Bank or
its representatives to inspect and copy, or furnish Bank or its representatives
with copies of, all records relating to the Collateral and the Obligation; and

   G.  POSSESSION OF COLLATERAL. Pledgor shall deliver a copy of this Agreement
(or other notice acceptable to Bank) to any Broker, financial intermediary, or
any other person in possession or any of the Collateral or on whose books the
interest of Pledgor in the Collateral appears, and such delivery shall
constitute notice to such person of Bank's security interest in the Collateral
and shall constitute Pledgor's instruction to such person to note Bank's
security interest on their books and records, or deliver to Bank certificates or
other evidence of the Collateral promptly upon Bank's request. Pledgor shall
deliver all investment securities and other instruments and documents which are
a part of the Collateral and in Pledgor's possession to Bank immediately, or if
hereafter acquired, immediately following acquisition, in a form suitable for
transfer by delivery or accompanied by duly executed instruments of transfer or
assignment in blank with signatures appropriately guaranteed in form and
substance suitable to Bank.

   H.  CHANGE OF NAME/STATUS. Pledgor shall not change its name, change its
corporate status, use any trade name or engage in any business not reasonably
related to its business as presently conducted.

   I.  POWER OF ATTORNEY. Pledgor appoints Bank and any officer thereof as
Pledgor's attorney-in-fact with full power in Pledgor's name and on Pledgor's
behalf to do every act which Pledgor is obligated to do or may be required to do
hereunder; however, nothing in this paragraph shall be construed to obligate
Bank to take any action hereunder nor shall Bank be liable to Pledgor for
failure to take any action hereunder. This appointment shall be deemed a power
coupled with an interest and shall not be terminable as long as the Obligation
is outstanding and shall not terminate on the disability or incompetence of
Pledgor. Without limiting the generality of the foregoing, Bank shall have the
right and power to receive, indorse and collect all checks and other orders for
the payment of money made payable to Pledgor representing any dividend, interest
payment or other distribution payable in respect of the Collateral or any part
thereof.

   J.  OTHER PARTIES AND OTHER COLLATERAL. No renewal or extensions of or any
other indulgence with respect to the Obligation or any part thereof, no
modification of the document(s) evidencing the Obligation, no release of any
security, no release of any person (including any maker, indorser, guarantor or
surety) liable on the Obligation, no delay in enforcement of payment, and no
delay or omission or lack of diligence or care in exercising any right or power
with respect to the Obligation or any security therefor or guaranty thereof or
under this Agreement shall in any manner impair or affect the rights of Bank
under any law, hereunder, or under any other agreement pertaining to the
Collateral. Bank need not file suit or assert a claim for personal judgment
against any person for any part of the Obligation or seek to realize upon any
other security for the Obligation, before foreclosing or otherwise realizing
upon the Collateral. Pledgor waives any right that can be waived to the benefit
of or to require or control application of any other security or proceeds
thereof, and agrees that Bank shall have no duty or obligation to Pledgor to
apply to the Obligation any such other security or proceeds thereof.

   K.  WAIVERS BY PLEDGOR. Pledgor waives notice of the creation, advance,
increase, existence, extension or renewal of, and of any indulgence with respect
to, the Obligation; waives presentment, demand, notice of dishonor, and protest;
waives notice of the amount of the Obligation outstanding at any time, notice of
any change in financial condition of any person liable for the Obligation or any
part thereof, notice of any Event of Default, and all other notices respecting
the Obligation; and agrees that maturity of the Obligation and any part thereof
may be accelerated, extended or renewed one or more times by Bank in its
discretion, without notice to Pledgor. Pledgor waives any right to require that
any action be brought against any other person or to require that resort be had
to any other security or to any balance of any deposit account. Pledgor further
waives any right of subrogation or to enforce any right of action against any
other pledgor until the Obligation is paid in full.

   L.  ADDITIONAL PROVISIONS. If one or more Riders to this Agreement are
executed by Pledgor, the covenants and provisions of each such Rider shall be
incorporated by reference into this Agreement (check applicable boxes).

   [ ] COLLATERAL MAINTENANCE RIDER: Pledgor agrees to maintain the Collateral
in accordance with the terms of the Collateral Maintenance Rider attached hereto
and made a part hereof for all purposes.

   [ ] RULE 144 RIDER: The Collateral is comprised in whole or in part of
control and/or restricted securities, which shall be subject to the additional
terms and provisions described on the Rule 144 Rider attached hereto and made a
part hereof for all purposes.

6. RIGHTS AND POWERS OF BANK.

   A.  GENERAL. Bank, before or after default, without liability to Pledgor may:
take control of proceeds, including stock received as dividends or by reason of
stock splits; release the Collateral in its possession to any Pledgor,
temporarily or otherwise; require additional Collateral; reject as
unsatisfactory any property hereafter offered by Pledgor as Collateral; take
control of funds generated by the Collateral, such as cash dividends, interest
and proceeds, and use same to reduce any part of the Obligation and exercise all
other rights which an owner of such Collateral may exercise, except the right to
vote or dispose of the Collateral before an Event of Default; and at any time
transfer any of the Collateral or evidence thereof into its own name or that of
its nominee. Bank shall not be liable for failure to collect any account or
instruments, or for any act or omission on the part of Bank, its officers,
agents or employees, except for its or their own willful misconduct or gross
negligence. The foregoing rights and powers of Bank will be in addition to, and
not a limitation upon, any rights and powers of Bank given by law, elsewhere in
this Agreement, or otherwise.

   B.  CONVERTIBLE COLLATERAL. Bank may present for conversion any Collateral
which is convertible into any other instrument or investment security or a
combination thereof with cash, but Bank shall not have any duty to present for
conversion any Collateral unless it shall have received from Pledgor detailed
written instructions to that effect at a time reasonably far in advance of the
final conversion date to make such conversion possible.

7. DEFAULT.

   A.  EVENT OF DEFAULT. An event of default ("Event of Default") shall occur
(a) if Pledgor or any other obligor on all or part of the Obligation shall fail
to timely and properly pay or observe, keep or perform any term, covenant,
agreement or condition in this Agreement or in any other agreement between
Pledgor and Bank or between Bank and any other obligor on the Obligation,
including but not limited to any other note or instrument, loan agreement,
security agreement, deed of trust, mortgage, promissory note, assignment or
other agreement or instrument concerning the Obligation; or (b) if Pledgor or
such other obligor shall fail to timely and properly pay or observe, keep or
perform any term, covenant, agreement or condition in any agreement between such
party and any affiliate or subsidiary of NationsBank Corporation.

   B.  RIGHTS AND REMEDIES. If any Event of Default shall occur, then, in each
and every such case, Bank may, without (a) presentment, demand, or protest, (b)

intent to accelerate all or any part of the Obligation, (d) notice of
acceleration of all or any part of the Obligation, or (e) notice of any other
kind, all of which Pledgor hereby expressly waives (except for any notice
required under this Agreement, any other loan document or which may not be
waived under applicable law), at any time thereafter exercise and/or enforce any
of the following rights and remedies, at Bank's option:

       i.  ACCELERATION. The Obligation shall, at Bank's option, become

obligation if any, of Bank to permit further borrowings under the Obligation 
sXXX at Bank's option immediately cease and terminate.

       ii. LIQUIDATION OF COLLATERAL. Sell, or instruct any Agent or Broker to
sell, all or any part of the Collateral in a public or private sale, direct any
Agent or Broker to liquidate all or any part of any Account and deliver all
proceeds thereof to Bank, and apply all proceeds to the payment of any or all of
the Obligation in such order and manner as Bank shall, in its discretion,
choose.

       iii. UNIFORM COMMERCIAL CODE. All of the rights, powers and remedies of a
secured creditor under the Uniform Commercial Code ("UCC") as adopted in the
jurisdiction to which Bank is subject under this Agreement.

       iv.  RIGHT OF SET OFF. Without notice or demand to Pledgor, set off and
apply against any and all of the Obligation any and all deposits (general or
special, time or demand, provisional or final) and any other indebtedness, at
any time held or owing by Bank or by any of Bank's affiliates or correspondents
to or for the credit of the account of Pledgor or any guarantor or indorser of
Pledgor's Obligation.

Pledgor specifically understands and agrees that any sale by Bank of all or part
of the Collateral pursuant to the terms of this Agreement may be effected by
Bank at times and in manners which could result in the proceeds of such sale as
being significantly and materially less than might have been received if such
sale had occurred at different times or in different manners, and Pledgor hereby
releases Bank and its officers and representatives from and against any and all
obligations and liabilities arising out of or related to the timing or manner of
any such sale.

If, in the opinion of Bank, there is any question that a public sale or
distribution of any Collateral will violate any state or federal securities law,
Bank may offer and sell such Collateral in a transaction exempt from
registration under federal securities law, and any such sale made in good faith
by Bank shall be deemed "commercially reasonable."

8. GENERAL.

   A.  PARTIES BOUND. Bank's rights hereunder shall inure to the benefit of its
successors and assigns, and in the event of any assignment or transfer of any of
the Obligation or the Collateral, Bank thereafter shall be fully discharged from
any responsibility with respect to the Collateral so assigned or transferred,
but Bank shall retain all rights and powers hereby given with respect to any of
the Obligation or the Collateral not so assigned or transferred. All
representations, warranties and agreements of Pledgor if more than one are joint
and several and all shall be binding upon the personal representatives, heirs,
successors and assigns of Pledgor.

   B.  WAIVER. No delay of Bank in exercising any power or right shall operate
as a waiver thereof; nor shall any single or partial exercise of any power or
right preclude other or further exercise thereof or the exercise of any other
power or right. No waiver by Bank of any right hereunder or of any default by
Pledgor shall be binding upon Bank unless in writing, and no failure by Bank to
exercise any power or right hereunder or waiver of any default by Pledgor shall
operate as a waiver of any other or further exercise of such right or power or
of any further default. Each right, power and remedy of Bank as provided for
herein or in any of the loan documents related to the Obligation, or which shall
now or hereafter exist at law or in equity or by statute or otherwise, shall be
cumulative and concurrent and shall be in addition to every other such right,
power or remedy. The exercise or beginning of the exercise by Bank of any one or
more of such rights, powers or remedies shall not preclude the simultaneous or
later exercise by Bank of any or all other such rights, powers or remedies.

   C.  AGREEMENT CONTINUING. This Agreement shall constitute a continuing
agreement. If the Obligation consists of All Debt, this Agreement shall apply to
all future as well as existing transactions, whether or not of the character
contemplated at the date of this Agreement, and if all transactions between Bank
and Pledgor shall be closed at any time, shall be equally applicable to any new
transactions thereafter. Provisions of this Agreement, unless by their terms
exclusive, shall be in addition to other agreements between the parties. Time is
of the essence of this Agreement.

   D.  DEFINITIONS. Unless the context indicates otherwise, definitions in the
UCC apply to words and phrases in this Agreement; if UCC definitions conflict,
Article 8 and/or 9 definitions apply.

   E.  NOTICE. Notice shall be deemed reasonable if mailed postage prepaid at
least 5 days before the related action (or if the UCC elsewhere specifies a
longer period, such longer period) to the address of Pledgor given above. Each
notice, request and demand shall be deemed given or made, if sent by mail, upon
the earlier of the date of receipt or five (5) days after deposit in the U.S.
Mail, first class postage prepaid, or if sent by any other means, upon delivery.

   F.  MODIFICATIONS. No provision hereof shall be modified or limited except by
a written agreement expressly referring hereto and to the provisions so modified
or limited and signed by Pledgor and Bank. The provisions of this Agreement
shall not be modified or limited by course of conduct or usage of trade.

   G.  PARTIAL INVALIDITY. The unenforceability or invalidity of any provision
of this Agreement shall not affect the enforceability or validity of any other
provision herein, and the invalidity or unenforceability of any provision of any
loan document related to the Obligation to any person or circumstance shall not
affect the enforceability or validity of such provision as it may apply to other
persons or circumstances.

   H.  APPLICABLE LAW AND VENUE. This Agreement has been delivered in the State
of Texas and shall be construed in accordance with the laws of that State. It
is performable by Pledgor in the county or city of Bank's address set out above
and Pledgor expressly waives any objection as to venue in any such location.
Wherever possible each provision of this Agreement shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision
of this Agreement shall be prohibited by or invalid under applicable law, such
provision shall be ineffective to the extent of such prohibition or invalidity,
without invalidating the remainder of such provisions or the remaining
provisions of this Agreement.

   I.  FINANCING STATEMENT. To the extent permitted by applicable law, a carbon,
photographic or other reproduction of this Agreement or any financing statement
covering the Collateral shall be sufficient as a financing statement.

   J.  ARBITRATION. ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE PARTIES HERETO
INCLUDING BUT NOT LIMITED TO THOSE ARISING OUT OF OR RELATING TO THIS
INSTRUMENT, AGREEMENT OR DOCUMENT OR ANY RELATED INSTRUMENTS, AGREEMENTS OR
DOCUMENTS, INCLUDING ANY CLAIM BASED ON OR ARISING FROM AN ALLEGED TORT. SHALL
BE DETERMINED BY BINDING ARBITRATION IN ACCORDANCE WITH THE FEDERAL ARBITRATION
ACT (OR IF NOT APPLICABLE, THE APPLICABLE STATE LAW), THE RULES OF PRACTICE AND
PROCEDURE FOR THE ARBITRATION OF COMMERCIAL DISPUTES OF J.A.M.S./ENDISPUTE OR
ANY SUCCESSOR THEREOF ("J.A.M.S."), AND THE "SPECIAL RULES" SET FORTH BELOW. IN

ANY BORROWER'S DOMICILE AT THE TIME OF THE EXECUTION OF THIS INSTRUMENT,
AGREEMENT OR DOCUMENT AND ADMINISTERED BY J.A.M.S. WHO WILL APPOINT AN

PERMITTED TO EXTEND THE COMMENCEMENT OF SUCH HEARING FOR UP TO AN ADDITIONAL 60

       ii. RESERVATION OF RIGHTS. NOTHING IN THIS ARBITRATION PROVISION SHALL 
           ---------------------                                       
BE DEEMED TO (I) LIMIT THE APPLICABILITY OF ANY OTHERWISE APPLICABLE STATUTES OF
LIMITATION OR REPOSE AND ANY WAIVERS CONTAINED IN THIS INSTRUMENT, AGREEMENT OR
DOCUMENT; OR (II) BE A WAIVER BY BANK OF THE PROTECTION AFFORDED TO IT BY 12
U.S.C. SEC. 91 OR ANY SUBSTANTIALLY EQUIVALENT STATE LAW; OR (III) LIMIT THE
RIGHT OF BANK HERETO (A) TO EXERCISE SELF HELP REMEDIES SUCH AS (BUT NOT LIMITED

PROPERTY, OR OBTAIN SUCH PROVISIONAL OR ANCILLARY REMEDIES BEFORE, DURING OR
AFTER THE PENDENCY OF ANY ARBITRATION PROCEEDING BROUGHT PURSUANT TO THIS
INSTRUMENT, AGREEMENT OR DOCUMENT. NEITHER THIS EXERCISE OF SELF HELP REMEDIES
NOR THE INSTITUTION OR MAINTENANCE OF AN ACTION FOR FORECLOSURE OR PROVISIONAL
OR ANCILLARY REMEDIES SHALL CONSTITUTE A WAIVER OF THE RIGHT OF ANY PARTY,
INCLUDING THE CLAIMANT IN ANY SUCH ACTION, TO ARBITRATE THE MERITS OF THE
CONTROVERSY OR CLAIM OCCASIONING RESORT TO SUCH REMEDIES.

   K.  CONTROLLING DOCUMENT. To the extent that this Agreement conflicts with
or is in any way incompatible with any other loan document concerning the
Obligation, any promissory note shall control over any other document, and if
such promissory note does not address an issue, then each other loan document
shall control to the extent that it deals most specifically with an issue.
