                                   PART I

ITEM 1.  BUSINESS

    South Texas Drilling & Exploration, Inc. and its subsidiaries (the
"Company") are engaged in the business of providing land contract drilling
services for the oil and gas industry; oil and gas exploration and development
activity for its own account; and operation of oil and gas wells for its own
account and those of outside investors. The revenues; earnings (loss) from
operations; identifiable assets; depreciation, depletion and amortization; and
capital expenditures are reported for each of its business segments for the
fiscal years ended March 31, 1996, 1995 and 1994 in note 5 ("Business Segments
and Supplementary Earnings Information") of the Notes to Consolidated Financial
Statements, which note is incorporated herein by reference.

                               CONTRACT DRILLING

    The Company currently owns four land drilling rigs with approximate depth
capabilities ranging from 6,000 feet to 11,500 feet.  Of these four rigs, three
were operated during all of fiscal 1996, while the fourth was placed in service
in May, 1995.  The Company also operated a fifth rig through the end of the
third quarter of fiscal 1996. The rig was owned by a partnership in which one
of the Company's wholly-owned subsidiaries was the general partner.  The
operations of the partnership are included in the Company's consolidated
financial statements.  In December, 1995, the partnership was terminated and
the Company's subsidiary sold its one-half interest in the drilling rig.  The
Company's rigs are presently operating in south Texas and along the Gulf Coast
of Texas.  All four of the rigs are currently in operation.

Drilling Equipment

    A land drilling rig consists of engines, drawworks, mast, pumps to
circulate the drilling mud, blowout preventors, drillstring and related
equipment.  The size and type of rig used depends upon well depth and site
conditions, among other factors.  A description of the type and capability of
the land drilling rigs operated by the Company is set forth in the following
table:

</TABLE>

    Minor repair work on the drilling rigs is performed on-site by the
Company's employees, but major repair work and overhaul of drilling equipment
on a contractual basis are performed by unaffiliated oil field service
companies. In the event of major breakdowns or mechanical problems, the
Company's rigs could be subject to significant idle time and a resulting loss
of revenue if such repair services were not immediately available.  The Company
engages in periodic maintenance and improvement of its drilling equipment and
believes that its drilling rigs and other related equipment are in good
operating condition.  The Company has experienced no substantial down time as
the result of repair or overhaul of its equipment.

    Principal materials, supplies and equipment necessary for drilling
operations are fuels to operate drilling equipment, drilling mud, tubular
steel, cement, drill bits, and other miscellaneous items.  Certain of these
items were in short supply from time to time during prior periods of high
drilling demand.  At the present time, the Company is not experiencing any
significant shortages of materials, supplies and equipment used in drilling,
and does not foresee any shortages materially affecting its operations.

Contracts

    All contracts under which the Company is presently conducting its land
drilling operations provide for rate charges determined on a daywork, footage
or turnkey basis, with rates dependent on the anticipated complexity of
drilling the well, on-site drilling conditions, the type of equipment to be
used, the Company's estimate of the risks involved, the duration of the work to
be performed and competitors' rates among other considerations.  Daywork
contracts provide for a fixed charge per day for drilling the well, and the
customer generally bears the major portion of the related costs and risks of
drilling.

    With certain limitations, contracts entered into on a footage basis provide
for an agreed price per foot drilled regardless of the time required or the
problems involved in drilling the well.  Related costs of drilling (i.e., rig
mobilization, labor, fuel usage and other costs) are included in the footage
charge.  As compared to daywork contracts, footage contracts involve a higher
degree of risk to the Company.

    Contracts entered into on a turnkey basis usually require the Company to
deliver to the operator a completed hole drilled to a specified depth.  In
addition to all costs incurred when drilling on a footage basis, the Company is
usually also responsible for drilling fluids, water and other costs.  As this
type of contract places a greater degree of risk on the Company than daywork or
footage contracts, the anticipated gross margin on this type of contract is
usually greater than on daywork or footage contracts.

    Drilling contracts are obtained either through competitive bidding or
through direct negotiation.  Contracts are usually entered into by the Company
covering the drilling of one well and obligate the Company to advance certain
costs and to assume certain expenses in connection with drilling operations.
During the year ended March 31, 1996 the Company drilled 48 wells with 54% of
contract drilling revenues attributable to daywork contracts, 20% to footage
contracts, and 26% to turnkey contracts.

    Uncertainty relating to oil and gas prices and the domestic gas surplus has
led to significant reductions in drilling activity by oil and gas producing
companies.  Furthermore, the phased-in reduction of the highest marginal income
tax rates applicable to individual investors has reduced commitments of capital
to oil and gas drilling funds.  Additionally, increased costs due to government
regulation have resulted in the movement of much of the drilling activities to
locations overseas.  The aggregate impact of these diverse economic factors has
resulted in significant reductions of oil company commitments to domestic oil
and gas exploration and consequent slackening of overall demand for drilling
rigs.

    During the year ended March 31, 1996, the largest customer of the Company's
drilling rigs was Columbia Gas Development Corp.  This customer accounted for
approximately 17% of contract drilling revenues of the Company during that
period.  No other single customer accounted for more than 10% of the Company's
contract drilling revenues for 1996.

    The Company actively markets its rigs and completed contracts for 27
customers in 1996, compared to 19 customers in 1995 and 24 customers in 1994.

    The loss of any of the Company's land drilling customers could have a
material adverse effect on the Company's business, particularly with respect to
the time required to find other users of the rig concerned.  See "Competitive,

Business and Operational Risks in Contract Drilling" in Part I.  During the
last quarter of fiscal 1991, drilling activity in south Texas began to decline,
although, there was marked increase in activity during the third quarter of
fiscal 1993 and the second and third quarters of fiscal 1994.  During the first
three quarters of fiscal 1995, drilling activity was stable but it decreased
significantly in the last quarter of the fiscal year primarily due to a fall in
natural gas prices.  In fiscal 1996 drilling activity returned to stability.
Since the 1991 decline, the Company has seen an increase in the number of
requests from current and potential customers for bids on footage and turnkey
terms.

Competitive, Business and Operational Risks in Contract Drilling

    The Company encounters substantial competition in its contract drilling
operations from other drilling contractors.  The usual method of competition in
the contract drilling industry is on the basis of price, customer relations,
rig availability and suitability, service, performance and condition of
equipment used.  Competition for contract drilling is primarily on a regional
basis, and many of the Company's competitors in south Texas have financial
resources, and technical staffs and facilities substantially greater than those
of the Company.  With the decline in drilling activity which began in the last
quarter of fiscal 1991, competition, especially as to price, has intensified.

    Land contract drilling in oil and gas operations is subject to a number of
operational risks and hazards including blowouts, cratering, fires and
explosions.  Any one of these happenings could cause serious damage to
equipment, personnel, property and/or the financial condition of the Company.
In addition, there is a risk that damage to the environment could result from
some of the Company's operations, particularly through oil spillage or
extensive, uncontrolled fires.  While the Company believes that it is
adequately insured against normal and foreseeable risks in its operations in
accordance with industry standards, such insurance may not be adequate to
protect the Company against liability from all consequences of well disasters,
extensive fire damage, or damage to the environment.  In the event that such
insurance was not adequate, the occurrence of a significant event could have a
material adverse effect on the Company's financial position and results of
operations.  Under current conditions, the Company anticipates that its present
insurance coverage will be maintained, but no assurance can be given that
insurance coverage will continue to be available at rates considered reasonable
or that certain types of coverage will be available at any cost.


                     OIL AND GAS OPERATIONS AND PROPERTIES

    The Company's oil and gas operations consist of the ownership of certain
oil and gas properties and the exploration, development and production of oil
and gas.  In June, 1992, the Company acquired operating interests in 17
producing wells.  During fiscal 1994 and fiscal 1995 the Company drilled three
additional wells.  No wells were added in fiscal 1996.

Productive Wells and Acreage

    At March 31, 1996, the Company had operating interests in 20 producing
wells in Texas.  Additionally, at March 31, 1996, the Company had additional
minor investments in working interests and overriding royalty interests in
productive wells and developed acreage in Texas.  However, the Company believes
the value and the amount of reserves in these properties are not significant in
relation to the value and the reserves in the operating interests. Therefore,
the working interests and overriding royalty interests have been omitted from
this report.  The following table presents information on the wells in which
the Company has an operating interest:

(1) A "productive well" is a well either producing or capable of producing oil
    or gas.  The Company owns no interests in wells with multiple completions.

(2) A "gross" well or acre is a well or acre in which a working interest is 
    owned.  "Net" wells or acres reflect the sum of fractional working 
    interests owned in gross wells or acreage.

(3) "Developed acreage" is acreage spaced or assigned to productive wells.

    Oil and gas properties in general are subject to customary royalty
interests contracted for in connection with the acquisition of title, liens
incident to operating agreements, liens for current taxes and other burdens and
minor encumbrances, easements, and restrictions.  The Company believes that the
existence of such burdens will not materially detract from the general value of
its working interests.

Exploration and Development

    The Company's oil and gas exploration and development activities consist of
the geological evaluation of prospective oil and gas properties, the
acquisition of working interests in oil and gas leases, and the production and
sale of oil and gas from such properties.  The Company participates as an
operator and a non-operator with other individuals, partnerships and
corporations in its oil and gas operations, as is customary in the industry.
In June, 1992, the Company acquired operating interests in 17 producing wells.
During fiscal 1994 and fiscal 1995 the Company drilled three additional wells.

    Net oil and gas reserves attributable to the interest of the Company,
quantities of oil and gas available to be produced by the Company and the
estimated future net revenue and present worth of future net revenue,
discounted at 10% per annum, have been estimated as set forth in Note 9, "Oil
and Gas Producing Activities", in the "Notes to Consolidated Financial
Statements" of this Report.  This note is incorporated herein by reference.

    The Company does not believe that there have been any major discoveries or
other favorable or adverse events since the date of the preparation of reserve
estimates which would cause a significant change in the estimated proved
reserves of future net revenue as set forth in "Oil and Gas Producing
Activities" of the "Notes to Consolidated Financial Statements" of this Report.

    Estimates of oil and gas reserves are projections based on engineering
information and data.  There are uncertainties inherent in the interpretation
of all such data, and there can be no assurance that the reserves will be
ultimately realized.

    Except for filing reserve data with the Securities and Exchange Commission
in various reports which are required to be filed under its rules, the Company
is not required to and does not file any reports of reserves with any federal
or state authority or agency.

    In prior years, the Company participated with small interests as a working
interest owner in various development wells.  The Company will participate in
development and exploratory wells in the future on a more focused basis and
with larger working interest participation.  Strategically, such investments
will be low to medium risk ventures and/or participation in producing
properties.  During the periods covered by this Report, the Company had no
investment in exploratory wells.  The following table sets forth certain
information with respect to the Company's investment in development wells
during the years indicated:

       Mcf of gas being equivalent to one barrel of oil.

Marketing and Customers

       Oil and gas produced by the Company are marketed under contracts in
accordance with usual industry practice.  Oil is sold under short-term
agreements for delivery at or near the well site at posted field prices which
may fluctuate depending on market conditions and the quality and classification
of the oil produced.

<PAGE>   7
           SOUTH TEXAS DRILLING & EXPLORATION, INC. AND SUBSIDIARIES

       The extent of demand for oil and gas and prices for oil and gas in
general depend on domestic production and consumption, the amount of foreign
oil imported and, in the case of gas, the proximity and capacity of natural gas
pipelines.  There can be no assurance that favorable market conditions will
exist in the future, nor can it be determined what effect, if any, future
regulation of the oil and gas industry will have upon the Company's marketing,
operations or production.

                            GOVERNMENTAL REGULATION

       Governmental regulations promulgated by various state and federal
authorities directly influence the Company's operations insofar as they
regulate operations of the Company's rigs, impact prices and therefore supplies
of and demands for oil and gas, and influence various costs associated with
petroleum exploration and production.

Regulation of Production

       The production of oil and gas is subject to extensive federal and state
laws, rules, orders and regulations governing a wide variety of matters.
Numerous departments and agencies, both federal and state, are authorized by
statute to issue and have issued rules and regulations binding on the oil and
gas industry and its individual members, some of which carry substantial
penalties for the failure to comply.

       State statutes and regulations require permits for drilling operations,
drilling bonds and reports concerning operations.  Most states in which the
Company operates or might operate also have statutes and regulations governing
conservation matters, including the unitization or pooling of oil and gas
properties, establishing of maximum rates of production from oil and gas wells
and the spacing of such wells.  Many states also restrict production to the
market demand for oil and gas.  Such statutes and regulations may limit the
rate at which oil and gas could otherwise be produced from the Company's
properties.  As a result of domestic crude oil shortages, there has been no
limit on allowable daily production on the basis of market demand since
mid-1972, although at some locations production continues to be regulated for
conservation purposes.  In addition to the direct costs borne in complying with
such regulations, operations and revenues may be impacted to the extent that
certain regulations limit oil and gas production to below economic levels.
Although the particular regulations applicable in each state in which
operations may be conducted vary, such regulations are generally designed to
ensure that oil and gas operations are carried out in a safe and efficient
manner and to ensure that similarly situated operators are provided with
reasonable opportunities to produce their respective fair shares of available
oil and gas reserves.  However, since these regulations generally apply to all
oil and gas producers, management of the Company believes that these
regulations should not put the Company at a material disadvantage to other oil
and gas producers.

Regulation of Sales and Transportation of Natural Gas

       Certain sales, transportation and resales of natural gas by the Company
are subject to both federal and state laws and regulations, including the
Natural Gas Act ("NGA") and the Natural Gas Policy Act of 1978 (the "NGPA") and
regulations promulgated by the Federal Energy Regulatory Commission (the
"FERC") under the NGA, the NGPA and other statutes.  The provisions of the NGA
and the NGPA, as well as the regulations thereunder, are complex and may affect
all who produce, resell, transport, purchase or consume natural gas.

       The FERC's transportation regulations primarily affect the operations of
the Company by virtue of the need to deliver the Company's gas production to
markets served by interstate or intrastate pipelines governed by these
regulations.  In most instances, interstate pipelines represent the only
available method of accomplishing such transportation.





                                     -7-
<PAGE>   8
           SOUTH TEXAS DRILLING & EXPLORATION, INC. AND SUBSIDIARIES

       Federal and state authorities have issued numerous orders during the
last several years governing the sale and transportation of natural gas and, no
doubt, will continue to issue other orders and actions which may significantly
affect the operations of the Company.

Price Controls on Liquid Hydrocarbons

       Sales of crude oil, condensate, and natural gas liquids by the Company
can at present be made at uncontrolled market prices.  While there are
currently no federal price controls on crude oil, condensate or natural gas
liquids, there can be no assurance that Congress will not reenact controls at a
future time.

Future Legislation

       Currently there are many legislative proposals pertaining to regulation
of the oil and gas industry, which may directly or indirectly affect the
Company's activities. No prediction can be made as to what additional energy
legislation may be proposed, if any, or which bills may be enacted or when any
such bills, if enacted, would become effective.

Regulation of the Environment

       The exploration, development, production and processing of oil and gas,
including the disposal of produced water, are subject to various federal and
state laws and regulations designed to protect the environment.  Compliance
with these regulations is part of the Company's day-to-day operating
procedures.  Infrequently, accidental discharge of such materials as oil,
natural gas, drilling fluids or contaminated water can and does occur.  Such
accidents can require material expenditures to correct.

       Various state and governmental agencies are considering, and some have
adopted, other laws and regulations regarding environmental control which could
adversely affect the business of the Company.  Compliance with such measures,
together with any penalties resulting from noncompliance therewith, may
increase the cost of oil and gas development, production and processing
operations or may affect the ability of the Company to complete existing or
future activities in a timely manner.

Compliance with Regulations

       The Company believes that it complies with all material legislation and
regulations affecting its operations in the drilling and operation of oil and
gas wells, and in controlling the discharge of wastes.  Compliance has not, to
date, materially affected the capital expenditures, earnings or competitive
position of the Company, although these measures add to the costs of operating
drilling equipment in some instances, and in others they may operate to reduce
drilling activity.  The Company does not expect to incur material capital
expenditures in the next fiscal year in order to comply with current
environmental control regulations.  Further legislation or regulation may
reasonably be anticipated, but the effects thereof on operations cannot be
predicted.

       The Company is subject to the requirements of the federal Occupational
Safety and Health Act ("OSHA") and comparable state statutes.  The OSHA hazard
communication standard, the Environmental Protection Agency "community
right-to-know" regulations under Title III of the Federal Superfund Amendment
and Reauthorization Act and comparable state statutes require the Company to
organize and report certain information about the hazardous materials used in
its operations to employees, state and local government authorities, and local
citizens.

           SOUTH TEXAS DRILLING & EXPLORATION, INC. AND SUBSIDIARIES

Taxation

       Although the Company's business is subject to many provisions of the
Internal Revenue Code, as amended, the depletion allowance and intangible
drilling costs have particular significance to the exploration, development and
production of oil and gas.  Certain state taxes influence operations as well.

Competitive and Operational Risks
       in Oil and Gas Exploration and Production

       The Company encounters substantial competition in its exploration and
development operations from other oil and gas companies.  The usual method of
competition in the exploration, development and production segment is on the
basis of lease acquisition, the cost of such acquisition, geologic information
and its cost, availability of rigs at reasonable cost, successful drilling,
completion and production, availability of pipelines if gas, and successful
negotiation of oil and gas sales contracts.  Many of the Company's competitors
have resources, technical staff and facilities substantially greater than those
of the Company.

       Exploration and development of oil and gas reserves involves certain
operational risks and hazards.  Among these are blowouts, cratering, fires and
explosions, and environmental damage, any one of which could potentially result
in loss of prospect value and liability to the Company.

                              PRINCIPAL CUSTOMERS

       During the fiscal year ended March 31, 1996, Columbia Gas Development
Corp. contributed 17% of the Company's total drilling revenues.  This was the
only customer to contribute 10% or more of the Company's total drilling
revenues.  See "Contract Drilling - Contracts" in this Item I.

                                   EMPLOYEES

       The Company's personnel are leased under an agreement with a personnel
leasing company.

       At May 25, 1996, the Company had 94 full-time leased personnel, of whom
78 were paid on an hourly basis and were engaged in operating the Company's
drilling rigs or in other operations.  Of the total personnel, nine were
administrative personnel and seven were supervisory.  None of the personnel are
represented by any union or collective bargaining group, and there is no
history of strikes, slow downs, or other material labor disputes. Management
believes that the Company's relations with the leased personnel are
satisfactory.

ITEM 2.  PROPERTIES

       For purposes of property description, see "Contract Drilling - Drilling
Equipment" and "Oil and Gas Operations and Properties" contained in this Part
I.  The Company's principal executive office in San Antonio, Texas is
maintained in office space which the Company purchased in September, 1995.  The
Company also owns a six-acre tract in Kenedy, Texas utilized as an operating
yard.

ITEM 3.  LEGAL PROCEEDINGS

       The Company is a defendant in several personal injury lawsuits of a type
which the Company considers routine for the contract drilling industry.  These
lawsuits arose out of injuries to personnel under lease from third party
employee leasing companies.  These lawsuits are being defended either by the
Company's general liability insurance carrier under what the Company considers
to be adequate coverage, or pursuant to an Indemnity





                                     -9-

           SOUTH TEXAS DRILLING & EXPLORATION, INC. AND SUBSIDIARIES

Agreement between the Company and the employee leasing company which employed
the Plaintiff.  The Company believes that the employee leasing company has
adequate insurance coverage to cover those claims.

       Among the lawsuits currently pending against the Company is National
Energy Group, Inc. v. South Texas Drilling Company, cause No. 96-98, 357
Judicial District Court, Willacy County, Texas.  This case arose out of a
dispute with a drilling customer over a billing for work performed under a
daywork drilling contract.  In the course of drilling the well, some of the
Company's equipment was lost in the hole.  Under the terms of the contract, the
customer was billed for the drilling operations and replacement cost of the
lost equipment.  The customer has declined to pay the billed amount of $279,000
alleging negligence and seeking damages in excess of $100,000.  This lawsuit is
being defended by the Company's general liability insurance carrier with a
rights of reservation letter. Discovery in this case is in the early stages and
depositions have not been completed.   However, the Company believes it has
meritorious defenses and is vigorously defending this litigation.  The Company
has filed a counter-suit seeking payment in full of the original invoice.

       Management believes the ultimate disposition of these matters will have
no material adverse effect on the consolidated financial statements of the
Company.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

       During the fourth quarter of the fiscal year covered by this report, no
matter was submitted to a vote of the Company's security holders through the
solicitation of proxies or otherwise.

                                    PART II

ITEM 5.  MARKET PRICE OF THE COMPANY'S COMMON STOCK AND RELATED SECURITY HOLDER
MATTERS

       The initial public offering of the Company's Common Stock occurred on
February 4, 1981, and from that date until August 18, 1981, the Common Stock
was traded in the over-the-counter market.  From August 19, 1981 until
February 10, 1986, the Company's Common Stock was listed on the American Stock
Exchange (AMEX) (Symbol: SDR).  On February 10, 1986, trading of the Company's
stock was discontinued on the AMEX as the Company no longer met the net worth
requirement for listing on the AMEX.  At the present time, the Company's Common
Stock (Symbol: STXD) is not traded on a stock exchange.  However, the Company's
Common Stock is traded in the "pink sheets".  Shareholders interested in
trading the Company's Common Stock should contact their stockbroker or the
Company for further information.  The following table sets forth for the period
indicated quotations from a marketmaker for the Company's common stock.

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

Liquidity

       The reduced level of drilling activity in the oil and gas industry
during the period of 1982-1989 had a detrimental effect on the Company's
operations.  Beginning in March, 1987, the Company experienced increased rig
utilization which continued until December, 1990. Beginning with the last
quarter of fiscal 1991, drilling activity in the Company's market area began to
decline and this lower level of activity continued through fiscal 1993 with a
brief surge of activity in November and December, 1992 and also during the
second and third quarters of fiscal 1994.  During the first three quarters of
fiscal 1995, drilling activity was stable but it decreased significantly in the
last quarter of the fiscal year primarily due to a fall in natural gas prices.
In fiscal 1996, drilling activity returned to a more stable level.  During
fiscal 1995, the utilization rate for the Company's rigs was 64 percent.
During that year, the Company operated four rigs.  In fiscal 1996, the
utilization rate remained at 64 percent.  However, in





                                    -11-
<PAGE>   12
           SOUTH TEXAS DRILLING & EXPLORATION, INC. AND SUBSIDIARIES

fiscal 1996, the Company operated or had available to operate five rigs. The
actual number of drilling days increased to 1,076 in fiscal 1996 from 842 in
fiscal 1995.  Drilling rates charged to customers on drilling contracts in
fiscal 1996 showed some increase over those charged in fiscal 1995.  This
increase in drilling rates reflects the increased demand for drilling rigs
during the period.  At March 31, 1996, the Company's current ratio was .51
compared to .59 at March 31, 1995.  Working capital at March 31, 1996 was
($1,104,828) compared to ($658,399) at March 31, 1995.  This decrease was due,
in part, to the effects of an uncollected trade receivable; increased current
portion of long-term debt incurred to acquire drilling equipment, transportation
equipment and land and building; and increased trade payables incurred  to
acquire, improve and maintain drilling equipment.

       During  fiscal 1996, the Company utilized its line of credit with its
bank on several occasions.  At March 31, 1996, the Company owed $200,000 on its
$200,000 line of credit.  This was necessary to offset the effect on the
Company's cash position of increased accounts receivables from drilling
operations.  Additional borrowings during the year included $300,000 for the
purchase of a drilling rig; $120,000 for additional drilling equipment;
$106,641 for the drilling of a well in which the Company has a 67.5% working
interest; $245,250 for the purchase of the Company's headquarters building in
San Antonio; and $31,575 for the purchase of transportation equipment.

       In May, 1996, the Company closed on a debt restructuring which included
a term loan of $1,250,000 and a revolving line of credit of $500,000, which has
allowed the Company to pay off all its bank debt with the exception of the loan
secured by the headquarters building in San Antonio and a minimal balance on
the loan secured by the oil and gas properties.  The new debt also allowed the
Company to pay off the seller financing on the rig purchased in May, 1995.
Proceeds from the new debt were also used to reduce trade accounts payable and
to provide funds for future drilling equipment purchases.  The term loan is
secured by drilling equipment, transportation equipment and the yard facility
in Kenedy, Texas.  The loan carries an interest rate of prime (8.25% at March
31, 1996) plus 3% and is payable in monthly payments of $14,881 plus interest.
Payments are based on a seven-year amortization and the loan is due in June,
1998.  The revolving loan is secured by the Company's trade accounts receivable
and carries an interest rate of prime plus 2.75%.

       During fiscal 1996, the Company negotiated with its Bank to have the
Bank's demand clause removed from all of the Company's debt with the Bank.
Because of the change the Company is able to classify as long-term the
long-term portion of the bank debt.  This results in a higher current ratio and
a lower working capital deficit than would have been reported had the demand
clause not been removed.

       The ratio of trade accounts receivable to total revenue increased to
7.1% at the end of fiscal 1996 from 3.6% at the end of fiscal 1995.  This
increase was the result of the increased drilling activity in the fourth
quarter of the fiscal year.  Due to the Company's incurring of additional debt
to purchase equipment and the minimal earnings incurred by the Company during
fiscal 1996, the ratio of the Company's shareholders' equity in relation to
outstanding debt (vendor and bank notes payable) decreased.  At March 31, 1995,
the ratio of shareholders' equity to notes payable was 1 to .46.  At March 31,
1996, the ratio had declined to 1 to .83.  Shareholders' equity was also
affected by a pending lawsuit in which the Company is the plaintiff in a cross
action filed in a Declaratory Judgment case filed by one of its Company's
insurers contesting payment of a personal injury judgment entered against the
Company.  Due to the uncertainty of the outcome of the case, the Company has
established a provision of $200,000 relating to the Company's obligation under
a judgment in a personal injury lawsuit in which the Company was the defendant
and represented by the insurer of its former employee leasing company.  If the
insurer should prevail in its Declaratory Judgment action the Company is
required to pay $200,000 over a three year period to the personal injury
plaintiff.  Since the insurer has refused to pay on the $200,000 judgment, the
Company has made payments of $45,000 to the personal injury plaintiff.  The
Company has also recorded a liability for the remaining $155,000 of which
$60,000 is classified as current portion of long-term debt and $95,000 as
long-term debt.

       The Company's liquidity was also affected by an uncollected account
receivable of $279,000 from drilling operations.  In this case, the Company
drilled a well under a daywork contract.  In the course of drilling the well,
some of the Company's equipment was lost in the hole.  Under the terms of the
contract, the customer was billed for the drilling operations and the
replacement cost of the lost equipment.  The customer filed a lawsuit alleging
negligence, denying responsibility for the $279,000 billed by the Company, and
seeking additional damages in excess of $100,000.  Management, which believes
the customer's claim to be without merit, has filed a counter-suit seeking
payment in full of the original invoice in the amount of $279,000.

Changes in Financial Condition

       During fiscal 1996, the Company had a net increase in property and
equipment of $844,000 before accumulated depreciation, depletion and
amortization.  Of this increase, $530,000 was attributable to the purchase of
drilling equipment, $7,000 to purchase or acquisition of oil and gas
properties, and $307,000 to the purchase of transportation and office
equipment, land and buildings and improvements.  The net increase in drilling
equipment included the addition of Rig 11 which was placed in service in May,
1995 and the disposal of Rig 10 in December, 1995.  Rig 11 was purchased for
$345,000 of which $45,000 was paid in cash and $300,000 was financed through
owner financing.  In December, 1995, a partnership in which a wholly-owned
subsidiary of the Company was the general partner distributed Rig 10 back to
the partners of the partnership.  The Company's subsidiary then sold its
one-half interest in the rig to the other partner for 319,767 shares of the
Company's stock.  The main component in the increase in transportation and
office equipment, land and buildings and improvements was the purchase of the
building which the Company occupies as its headquarters in San Antonio, Texas.
The building was purchased for $273,000 of which $137,000 was financed by a
bank and $114,000 was financed by the Small Business Administration.

       At March 31, 1996, current debt and notes payable were $667,000.  Of
this amount, $277,000 was owed on oil and gas properties, $200,000 on the line
of credit, $98,000 on drilling equipment, $7,000 on the yard facility, $13,000
on land and buildings and improvements, $12,000 on transportation equipment and
$60,000 as the current amount of the loss related to the personal injury claim
discussed above in the "Liquidity" section of this ITEM 7. Trade accounts
payable at March 31, 1996 were $1,256,000 compared to $764,000 at March 31,
1995.  At March 31, 1996, long-term debt was $554,000.  Of this amount,
$232,000 was owed on land and buildings and equipment; $126,000 on drilling
equipment; $95,000 long-term portion of the $200,000 contingent obligation on
the possible lawsuit judgment related to the personal injury claim; $73,000 to
an employee for unpaid salary and $28,000 on transportation equipment.

Results of Operations

       Rig utilization rates for the years ended March 31, 1996, 1995 and 1994
were 64%, 64% and 57%, respectively.  In fiscal 1996, the Company completed
1,076 drilling days while in fiscal 1995, the Company completed 842 drilling
days.  This was a 28% increase compared to fiscal 1995 in the number of
drilling days.  This increase reflects the increased demand during the period
for drilling rigs and the increased efforts of the Company's staff to obtain
contracts for the rigs.

       During fiscal 1996, the Company's drilling margin increased when
compared to fiscal 1995 and it decreased when compared to fiscal 1994.  In
fiscal 1996, the drilling margin was $912,230, while in fiscal 1995 and fiscal
1994 it was $539,801 and $1,149,247, respectively.  The increase in fiscal 1996
over fiscal 1995 was principally the result of the 28% increase in the number
of drilling days during fiscal 1996.  The drilling margin in 1996 was less than
1994 because of increased repairs, maintenance and operating costs.

       The Company markets its rigs to a number of customers.  In fiscal 1996,
the Company drilled for 27 different customers.  In fiscal 1995, the Company
drilled for 19 different customers.  Of the 27 customers in fiscal





                                    -13-

           SOUTH TEXAS DRILLING & EXPLORATION, INC. AND SUBSIDIARIES

1996, 22 were customers the Company had not drilled for in fiscal 1995.  These
22 customers accounted for over 68% of the Company's drilling revenue in fiscal
1996.  In fiscal 1994, two customers accounted for 23% of total drilling
revenue.  In fiscal 1995, two customers accounted for 36% of total drilling
revenue.  In fiscal 1996, three customers accounted for 34% of total drilling
revenue.  Of these three customers, only one was included in the top two
customers of fiscal 1995.  The loss of any of these customers could have a
material adverse effect on the Company's business for the time required to find
other users of the rig concerned.

       Oil and gas revenue for fiscal 1996 decreased by $25,299 from fiscal
1995.  The decrease was primarily due to a 22% decrease in oil production and a
4% decrease in the average price per MCF of gas.  These decreases were offset
to an extent by a 22% increase in gas production and a 4% increase in the
average price per barrel of oil. In fiscal 1996, the Company's average
production cost per unit in barrel equivalents increased 4% from fiscal 1995.
This compares with a 8% decrease in the average production cost for 1995
compared to 1994.

       Depreciation, depletion and amortization expense in fiscal 1996
increased to $576,894 from $475,708 in fiscal 1995.  Depreciation expense
increased to $384,400 in fiscal 1996 from $277,986 in fiscal 1995.  This
increase was the result of equipment purchased in late fiscal 1995 and fiscal
1996.  Depletion expense decreased to $192,494 in fiscal 1996 compared to
$197,722 in fiscal 1995.  Production decreased to 27,227 barrel equivalents in
fiscal 1996 from 27,948 barrel equivalents in fiscal 1995.  In fiscal 1996, the
Company was not subject to the ceiling test limitation as it applies to oil and
gas properties.  Under such a test, the depleted carrying value of the
Company's oil and gas properties is compared to the net present worth of
estimated future oil and gas revenues, discounted at 10%.  If the depleted
carrying value exceeds the discounted net present worth of estimated future oil
and gas revenues, the carrying value must be written down.  Conversely, if the
discounted net present value exceeds the carrying value of the properties, no
adjustment is made to the carrying value, even if there had been a write-off in
prior years.

       General and administrative expenses increased from $450,609 in fiscal
1995 to $520,402 in fiscal 1996.  The primary reasons for the increase were an
increase in payroll costs associated with additional personnel and costs
incurred related to the annual meeting in August, 1995.

       Earnings (loss) from operations increased to $15,608 in fiscal 1996 from
($222,900) in fiscal 1995.  Of the $15,608, ($65,506) was contributed by
drilling operations and $81,114 by oil and gas operations.  When compared with
oil and gas operations, drilling operations generate significantly more
revenue, but they are far more costly, requiring large expenditures for
equipment, personnel and maintenance and repairs.  Oil and gas operations, on
the other hand, normally do not require significant expenditures once the
original purchase or investment is accomplished.  Oil and gas operations
require limited personnel involvement to produce the oil and gas, whereas
drilling operations require continuous involvement of significant numbers of
personnel to complete a contract.

       The exploration, development, production and processing of oil and gas,
including the disposal of produced water, are subject to various federal and
state laws and regulations designed to protect the environment.  Compliance
with these regulations is part of the Company's day-to-day operating
procedures.  The Company is not aware of any potential clean-up obligations
which would have a material effect on its financial condition or results of
operations.

       In March, 1995, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No.  121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of".
This Statement requires that long-lived assets and certain identifiable
intangibles to be held and used by an entity be reviewed for impairment
whenever events or changes in circumstances indicate that the carrying amount
of an asset may not be recoverable.  This Statement requires that long-lived
assets and certain identifiable intangibles to be disposed of be reported at
the lower of carrying amount or fair value less cost to sell.  This Statement
is not expected to impact the Company's oil and gas properties as they are
accounted for under the full





                                    -14-

           SOUTH TEXAS DRILLING & EXPLORATION, INC. AND SUBSIDIARIES

cost accounting method.  The Company has not yet performed an analysis of the
impact of implementation of this Statement on its drilling rigs and equipment.
The Company is required to adopt this Statement in fiscal year 1997.

       In October, 1995, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No.  123, "Accounting for
Stock-Based Compensation," which requires adoption of the disclosure provisions
no later than fiscal years beginning after December 15, 1995.  This Statement
establishes financial accounting and reporting for stock-based employee
compensation plans, including stock purchase plans, stock option plans,
restricted stock and stock appreciation rights.  The Statement requires a fair
value based method of accounting for employee stock options or similar
instruments and encourages a similar method for all employee stock compensation
plans.  This method measures compensation cost at the grant date based on the
value of an award and recognizes it over the service period, usually the
vesting period.  However, the Statement also allows an entity to continue
measuring compensation cost for such plans using the intrinsic value method of
accounting prescribed by Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees", provided pro forma disclosures are
made.  The Company has not yet determined the effect the new standard will have
on net income and earnings per share should it elect to make such a change.

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA


                          Independent Auditors' Report



The Board of Directors
South Texas Drilling & Exploration, Inc.:

       We have audited the consolidated balance sheets of South Texas Drilling
& Exploration, Inc. and subsidiaries as of March 31, 1996 and 1995 and the
related consolidated statements of operations, shareholders' equity and cash
flows for each of the years in the three-year period ended March 31, 1996.  In
connection with our audits of the consolidated financial statements, we also
have audited the financial statement schedule (Schedule II) for each of the
years in the three-year period ended March 31, 1996.  These consolidated
financial statements and financial statement schedule are the responsibility of
the Company's management.  Our responsibility is to express an opinion on these
consolidated financial statements and financial statement schedule 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 misstatements.  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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of South Texas
Drilling & Exploration, Inc. and subsidiaries as of March 31, 1996 and 1995,
and the results of their operations and their cash flows for each of the years
in the three-year period ended March 31, 1996, in conformity with generally
accepted accounting principles.  Also in our opinion, the related financial
statement schedule, when considered in relation to the basic consolidated
financial statements taken as a whole, presents fairly, in all material
respects, the information set forth therein.

                   Notes to Consolidated Financial Statements

(1)   Organization and Summary of Significant Accounting Policies

         Business and Principles of Consolidation

              The Company provides land contract drilling services for the oil
         and gas industry, primarily in southern Texas, and engages in oil and
         gas exploration and development activity for its own account.  The
         consolidated financial statements include the accounts of the Company,
         its wholly-owned subsidiaries and its limited partnership interest
         through December, 1995.  All significant intercompany accounts and
         transactions have been eliminated in consolidation.

              The financial statements have been prepared in accordance with
         generally accepted accounting principles.  In preparing the financial
         statements, management is required to make estimates and assumptions
         that affect the reported amounts of assets and liabilities as of the
         dates of the balance sheets and income and expenses for the periods.
         Actual results could differ significantly from those estimates.
         Material estimates that are particularly susceptible to significant
         changes in the near term relate to the determination of depreciation,
         depletion and amortization expense.

         Reclassifications

              Certain reclassifications of prior period amounts have been made
         to conform with the current period presentation.

         Income Taxes

              The Company files a consolidated Federal income tax return with
         its subsidiaries using a December 31 year- end.

              Pursuant to Statement of Financial Accounting Standards No. 109,
         "Accounting for Income Taxes", the Company follows the asset and
         liability method of accounting for income taxes under which deferred
         tax assets and liabilities are recognized for the future tax
         consequences attributable to differences between the financial
         statement carrying amounts of existing assets and liabilities and
         their respective tax bases.  Deferred tax assets and liabilities are
         measured using enacted tax rates expected to apply to taxable income
         in the years in which those temporary differences are expected to be
         recovered or settled.  Under Statement 109, the effect on deferred tax
         assets and liabilities of a change in tax rates is recognized in
         income in the period that includes the enactment date.

         Earnings (Loss) Per Common Share

              Earnings (loss) per common and common equivalent share are based
         upon the weighted average number of outstanding shares during each
         period. Dilutive common equivalent shares consist of stock warrants
         and the weighted average is computed using the treasury stock method.
         Earnings (loss) per share computed on a fully diluted basis is not
         presented as it is not significantly different from earnings (loss)
         per share computed on a primary basis.



                                                                     (Continued)

         Contract Drilling in Progress

              Contract drilling revenues are earned on footage, daywork and
         turnkey contracts and such revenues and related costs are included in
         the determination of earnings as work progresses.  Contract drilling
         in progress consists of revenues earned on contracts which have not
         yet been billed.

         Property and Equipment

              Oil and gas producing activities are accounted for using the full
         cost method.  Under the full cost method, all costs incurred in the
         acquisition, exploration and development of all oil and gas
         properties, including surrendered and abandoned leaseholds, delay
         lease rentals and dry hole costs, are capitalized. All costs related
         to production, general corporate overhead and other similar activities
         are expensed in the period incurred.

              Depletion of oil and gas properties is provided by the unit of
         production method based on the Company's interest in the aggregated,
         estimated recoverable reserves of all properties.  Depletion includes
         a ceiling limitation adjustment required under the full cost method of
         accounting.  The ceiling limitation adjustment is applicable when the
         carrying value of oil and gas properties exceeds the discounted net
         present worth of estimated future cash flows on those properties.

              Depreciation of drilling, transportation and other equipment is
         provided using the straight-line method over estimated useful lives
         ranging from three to ten years.

              Maintenance and repairs are charged to operations; renewals and
         betterments are charged to appropriate property and equipment
         accounts.

         Cash Equivalents

              For purposes of the statements of cash flows, the Company
         considers all highly liquid debt instruments purchased with a maturity
         of three months or less to be cash equivalents.

(2)   Notes Payable and Long-term Debt

              As of March 31, 1996 and 1995, the Company had established a line
         of credit with a bank enabling the Company to borrow up to $200,000 at
         the bank's prime rate (9.25%  at March 31, 1996 and 10.0% at March 31,
         1995) all of which was outstanding as of March 31, 1996 and 1995.  The
         line of credit would have been due October 21, 1996, however, it was
         paid in full through a debt restructuring accomplished in May, 1996
         and more fully described in footnote No. 8, "Subsequent Events."  The
         Company had no other credit facilities at March 31, 1996 except for
         the long-term debt described below:

              Long-term debt maturing each year subsequent to March 31, 1996 is
         as follows:  1997 - $467,416; 1998 - $268,001; 1999 - $78,296; 2000 -
         $21,627; 2001 and thereafter- $185,992.

              At March 31, 1996, the Company was in compliance with various
         negative and affirmative covenants on its note payable to bank,
         secured by oil and gas properties.  Such covenants included the
         maintenance of at least $25,000 in depository accounts at the bank and
         a net worth of at least $400,000 at all times.

              Note a:  On April 14, 1995, the Company executed a Master Real
         Estate Lien Note in the amount of $800,000 with a bank.  This note
         provides the Company with a $400,000 "Guidance Line of Credit
         Facility" to be used for drilling, completion and equipping expenses
         of wells to be drilled.  This note has an interest rate of one percent
         over the Bank's prime rate, 9.25% at March 31, 1996, and is due
         January 1, 1997.  In addition to the Guidance Line of Credit Facility,
         the Master Note covers the other notes executed by the Company in
         favor of the Bank, the line of credit, the loan secured by the yard
         facility in Kenedy and the loan secured by oil and gas properties
         purchased in 1992 and drilled in 1993.  Subsequent to the execution of
         the Master Real Estate Lien Note, the bank has funded $107,000 to the
         Company.

              Note b:  In May, 1995, the Company purchased an additional land
         drilling rig for $345,000. $300,000 of the purchase price was financed
         by the seller through a note payable in monthly payments of $9,540
         including interest at 9.0%.  This note has a three year term.

              Note c:  In September, 1995, the Company executed a note payable,
         in the amount of $245,250, to a bank for the purchase of the office
         building which the Company occupies as its headquarters in San
         Antonio, Texas.  The note has a term of ten years and is payable in
         monthly payments of $1,900 including interest at 0.5% over the Bank's
         prime rate, 9.25% at March 31, 1996.  In November, 1995 the Company
         closed on financing with the Small Business Administration which
         became a second lien on the headquarters building.  The loan is in the
         amount of $114,000 and was used to pay down the amount borrowed from
         the bank for the purchase.  This debt has a 20 year term and is
         payable in monthly payments of $921 including interest at 6.713%.

              Subsequent to the end of fiscal 1996, the Company restructured a
         majority of its bank and long-term debt.  See footnote 8, "Subsequent
         Events".

(3)   Income Taxes

              Due to the utilization of net operating loss carryforwards, the
         Company had no Federal income tax liability at March 31, 1996 or 1995.



                                                                     (Continued)

                   Notes to Consolidated Financial Statements

              At March 31, 1996, for Federal income tax purposes the Company
         had a net operating loss carryforward of approximately $15,820,000 and
         investment tax credit carryforwards of approximately $671,000
         available to offset future taxable income and taxes.

              Unless utilized, net operating loss and investment tax credit
         carryforwards will expire as follows:

              A valuation allowance has been established to decrease total
         gross deferred tax assets to the amount of the total gross tax
         liabilities due to the uncertainties involved in the ultimate
         realization of the deferred

         tax assets.  The valuation allowance for deferred tax assets at March
         31, 1995 was $6,158,000.  The net change in total valuation allowance
         for the year ended March 31, 1996 was a decrease of $287,000 due to the
         change in the corresponding gross deferred tax assets and liabilities.

(4)  Stock Options and Warrants

              In December, 1988, the Board of Directors issued certain
         directors, officers and employees warrants to purchase 435,000 shares
         of the Company's common stock at $.15 per share, of which three
         warrants for a total of 55,000 shares have been exercised as of March
         31, 1996 and two warrants for 245,000 shares have been canceled.
         These warrants are exercisable upon issuance and expire December 8,
         1998.  As of March 31, 1996, 135,000 shares of Common stock were
         reserved for future issuance in connection with warrants issued to
         employees, directors, officers and former employees.

              In August, 1992, the Board of Directors issued certain directors,
         officers and employees warrants to purchase 235,000 shares of the
         Company's stock at $.10 per share, all of which have been exercised as
         of March 31, 1996.

              On May 1, 1995, the Board of Directors issued an option to Mr.
         Locke, President and Chief Executive Officer, to purchase 1,200,000
         shares of the Company's common stock at $.375 per share.  This option
         expires on May 1, 2005.  At March 31, 1996, 100,000 shares have been
         purchased under this option.

              On June 15, 1995, the Board of Directors issued certain
         directors, officers and employees options to purchase 128,500 shares
         of the Company's common stock at $.375 per share, none of which has
         been exercised as of March 31, 1996.

              In October, 1995, the Financial Accounting Standards Board issued
         Statement of Financial Accounting Standards No. 123, "Accounting for
         Stock-Based Compensation," which requires adoption of the disclosure
         provisions no later than fiscal years beginning after December 15,
         1995.  This Statement establishes financial accounting and reporting
         for stock-based employee compensation plans, including stock purchase
         plans, stock option plans, restricted stock and stock appreciation
         rights.  The Statement requires a fair value based method of
         accounting for employee stock options or similar instruments and
         encourages a similar method for all employee stock compensation plans.
         This method measures compensation cost at the grant date based on the
         value of an award and recognizes it over the service period, usually
         the vesting period. However, the Statement also allows an entity to
         continue measuring compensation cost for such plans using the
         intrinsic value method of accounting prescribed by Accounting
         Principles Board Opinion No. 25, "Accounting for Stock Issued to
         Employees", provided pro forma disclosures are made.  The Company has
         not yet determined the effect the new standard will have on net income
         and earnings per share should it elect to make such a change.


                                                                     (Continued)

                                                                     (Continued)

            The intersegment revenue that is eliminated in the above tables
       represents the reduction in drilling revenue due to full cost accounting
       for oil and gas properties.  Under such method, drilling revenue from
       wells where the Company owns a working interest can only be recognized
       to the extent it exceeds the total cost of the well, including the cost
       to acquire the interest.  There were no such participations in fiscal
       1996 or fiscal 1995.  Therefore, there were no eliminations in those
       years.

(6)  Related Party Transactions

            A director owns an interest in several oil and gas properties in
       which the Company owns an interest. Two directors own interests in the
       well which the Company drilled in February, 1995 and continues to
       operate.

(7)  Commitments and Contingencies

            Rental expense for the years ended March 31, 1996, 1995, and 1994
       was $2,421, $15,825, and $13,275, respectively.

            The Company is a defendant in several personal injury lawsuits of a
       type which the Company considers routine for the contract drilling
       industry.  These lawsuits arose out of injuries to personnel under lease
       from third party employee leasing companies.  These lawsuits are being
       defended either by the Company's general liability insurance carrier
       under what the Company considers to be adequate coverage, or pursuant to
       an Indemnity Agreement between the Company and the employee leasing
       company which employed the Plaintiff. The Company believes that the
       employee leasing company has adequate insurance coverage to cover those
       claims.

            Among the lawsuits currently pending against the Company is
       National Energy Group, Inc. v. South Texas Drilling Company, cause No.
       96-98, 357 Judicial District Court, Willacy County, Texas.  This case
       arose out of a dispute with a drilling customer over a billing for work
       performed under a daywork drilling contract.  In the course of drilling
       the well, some of the Company's equipment was lost in the hole.  Under
       the terms of the contract, the customer was billed for the drilling
       operations and replacement cost of the lost equipment.  The customer has
       declined to pay the billed amount of $279,000 alleging negligence and
       seeking damages in excess of $100,000.  This lawsuit is being defended
       by the Company's general liability insurance carrier with a rights of
       reservation letter.  Discovery in this case is in the early stages and
       depositions have not been completed.  Therefore, it is impractical to
       render an opinion about whether the likelihood of an unfavorable outcome
       is either "probable" or "remote".  However, the Company believes it has
       meritorious defenses and is vigorously defending this litigation.  The
       Company has filed a counter-suit seeking payment in full of the original
       invoice.

            Management believes the ultimate disposition of these matters will
       have no material adverse effect on the consolidated financial statements
       of the Company.

(8)  Subsequent Events

            In May, 1996, the Company closed on a debt restructuring which
       included a term loan of $1,250,000 and a revolving line of credit of
       $500,000,  which has allowed the Company to pay off all its bank debt
       with the exception of the loan secured by the headquarters building in
       San Antonio and a minimal balance on the loan secured by the oil and gas
       properties.  The new debt also allowed the Company to pay off the seller


                                                                     (Continued)

       financing on the rig purchased in May, 1995.  Proceeds from the new debt
       were also used to reduce trade accounts payable and to provide funds for
       future drilling equipment purchases.  The term loan is secured by
       drilling equipment, transportation equipment and the yard facility in
       Kenedy, Texas.  The loan carries an interest rate of prime (8.25% at
       March 31, 1996) plus 3% and is payable in monthly payments of $14,881
       plus interest. Payments are based on a seven-year amortization and the
       loan is due in June, 1998.  The revolving loan is secured by the
       Company's trade accounts receivable and carries an interest rate of prime
       plus 2.75%.

(9)  Oil and Gas Producing Activities (Unaudited)

            The Company's oil and gas properties and operations are presented
       in the consolidated financial statements on the full cost method of
       accounting.  All of the Company' exploration and production is conducted
       in the United States.

            The aggregate amount of capitalized costs relating to oil and gas
       producing activities at the dates indicated are as follows:

            During the periods indicated in the preceding table, no internal
       costs were capitalized.  Internal costs incurred during these periods
       were in the nature of general corporate overhead.  All costs related to
       production, general corporate overhead and other similar activities are
       expensed in the period incurred. Costs of site restoration and
       dismantlement and abandonment have historically been equal to or less
       than revenue earned from salvage of the well equipment.  Such costs, net
       of the salvage revenue, are added to or subtracted from the full cost of
       oil and gas properties.  These costs have been minimal in the years
       being reported.

              The following is a standardized measure of the discounted net
         future cash flows and changes applicable to proved oil and gas
         reserves required by FASB 69.  The future cash flows are based on
         estimated oil and gas reserves utilizing prices and costs in effect as
         of year end discounted at 10% per year and assuming continuation of
         existing economic conditions.

              The standardized measure of discounted future net cash flows, in
         management's opinion, should be examined with caution.  The basis for
         this table is a reserve study, as prepared by an in-house petroleum
         engineer, which contains estimates of quantities and rates of
         production of reserves.  Revisions of previous year estimates can have
         a significant impact on these 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.  Therefore, the standardized measure of discounted future
         net cash flow is not necessarily a "best estimate" of the fair value
         of the Company's proved oil and gas properties.


                                                                     (Continued)

(10) Minority Interest in Partnership

              In August, 1994, the Company, through one of its wholly-owned
         subsidiaries, became the managing and general partner of a partnership
         whose purpose was to operate a drilling rig contributed to the
         partnership by the two partners.  The partnership operated the rig
         through December 20, 1995 at which





                                    -34-

                   Notes to Consolidated Financial Statements


         time the rig was distributed back to the partners and the partnership
         was terminated.  The Company's subsidiary then sold its remaining
         one-half interest in the rig to the other partner.  Since the Company
         is no longer involved in the operations of the rig, the Company was
         able, in fiscal 1996, to recognize the gain on the sale of the rig
         which was deferred in fiscal 1995 when the first one-half interest in
         the rig was sold. In exchange for the rig, the Company received
         $250,000 in cash and 319,767 shares of the Company's common stock.  The
         gain attributable to the disposition of the rig was $183,000.

(11) Liquidity

              In order to improve its financial position, management plans to
         increase utilization of its drilling rigs, reduce indebtedness and
         increase its base of oil and gas producing properties.  Management
         anticipates an improved working capital position in 1997 and believes
         that by emphasizing the above plans, in conjunction with its
         continuing commitment to closely monitor operational costs, the
         Company will improve both its results of operations and its financial
         position.  The debt restructuring discussed in Note 8, "Subsequent
         Events." will allow the Company to improve its current position.  The
         new debt allowed the Company to reduce its current debt obligations
         and to reduce accounts payable.  This will improve the Company's
         current ratio and reduce its working capital deficit.  The removal of
         its demand clause by the Bank from its debt will also improve the
         Company's current ratio and reduce its working capital deficit.

(12) Fair Value of Financial Instruments

     Cash, trade receivables and payables and short-term debt:

              The Company holds cash, trade receivables and payables and
         short-term debt.  The carrying amount of these instruments
         approximates fair value due to the short maturity of the instruments.

     Long-term debt:

              The carrying amount of the Company's long-term debt approximates
         fair value due to the recentness of the issuance of the debt.

ITEM 13.      CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

              The Company's president and chief executive officer, Mr. Wm.
         Stacy Locke, commenced employment by the Company on May 1, 1995, under
         a two year employment agreement calling for a base salary of $100,000
         for the first year of the two year term and $150,000 for year two.
         $20,000 of Mr. Locke's first year's salary will be payable in Common
         Stock valued at the average market value of such shares during March,
         1996.  Likewise, $55,000 of the $150,000 salary payable to Mr. Locke
         during the second year of his employment with the Company is payable
         in Common Stock valued at its average market value during March, 1997.
         Furthermore, if the Company should experience a loss for the last two
         consecutive quarters of the term of Mr. Locke's employment agreement
         the $55,000 payable in Common Stock for the second year of Mr. Locke's
         employment shall be reduced to $30,000.  The Company may terminate Mr.
         Locke's employment agreement without cause at any time after May 1,
         1996 and prior to the end of its two year term, upon payment to him of
         $75,000 in cash and the issuance to him of a five-year warrant to 
         purchase 120,000 shares of Common Stock at $0.375 per share.

              The terms of Mr. Locke's agreement require the Company to issue
         ISO's to Mr. Locke for 1,200,000 shares of Common Stock with an
         exercise price of $.375 per share.  While Mr. Locke remains employed
         by the Company and after the earlier to occur of (i) May 1, 1998 or
         (ii) the acquisition by Mr. Locke of at least 10% of the Company's
         outstanding Common Stock, on a fully diluted basis, and assuming the
         exercise of all exercisable stock options held by Mr. Locke, on each
         May 1 Mr. Locke may accelerate his ability to exercise all or any part
         of the options to purchase 240,000 shares of Common Stock which would
         otherwise become exercisable on the next following May 1 under his ISO
         up to the amount necessary for him to achieve or maintain the 10%
         ownership of Common Stock determined as described above.  After all of
         Mr. Locke's ISO's become exercisable, the Company has agreed to issue
         additional ISO's (or non- qualified options if ISO's cannot be made
         available) covering up to 240,000 shares on each May 1 at an exercise
         price equal to the then market value of Common Stock in order to
         provide Mr. Locke with an opportunity to acquire and maintain
         ownership of 10% of the Company's Common Stock on the basis described
         above.  In the event the Company shall receive gross cash proceeds of
         $10 million or more in connection with an underwritten public offering
         of Common Stock, Mr. Locke's rights to additional options shall cease.

subject to deduction of reserves for accrued interest and such other reserves
as FINOVA deems proper from time to time, and less amounts FINOVA may be

interest on the outstanding principal amount of any Overline, on demand, at the
rate set forth on the Schedule.

3.2       Default Interest Rate. Upon the occurrence and during the
continuation of an Event of Default, Borrower shall pay FINOVA interest on the

balance of the Term Loan at the default rate set forth in Section 5.0 of the 
Term Loan Note.

3.3      Examination Fees. Borrower agrees to pay to FINOVA an examination fee
in the amount set forth on the Schedule in connection with each audit or
examination of Borrower performed by FINOVA prior to or after the date hereof.
Without limiting the generality of the foregoing, Borrower shall pay to FINOVA
an initial examination fee in an amount equal to the amount set forth on the
Schedule. Such initial examination fee shall be deemed fully earned at the time
of payment and due and payable upon the closing of this transaction, and shall
be deducted from any good faith deposit paid by Borrower to FINOVA prior to the
date of this Agreement.

3.4      Excess Interest. The contracted for rate of interest of the loan
contemplated hereby, without limitation, shall consist of the following: (i)
the interest rate set forth on the Schedule, calculated and applied to the
principal balance of the Obligations in accordance with the provisions of this
Agreement; (ii) interest after an Event of Default, calculated and applied to
the amount of the Obligations in accordance with the provisions hereof; and
(iii) all Additional Sums (as herein defined), if any. Borrower agrees to pay
an effective contracted for rate of interest which is the sum of the
above-referenced elements. The examination fees, attorneys fees, expert witness
fees, letter of credit fees, collateral monitoring fees, closing fees, facility
fees, Termination Fees, Minimum Interest Charges, other charges, goods, things
in action or any other sums or things of value paid or payable by Borrower
(collectively, the "Additional Sums"), whether pursuant to this Agreement or
any other documents or instruments in any way pertaining to this lending
transaction, or otherwise with respect to this lending transaction, that under
any applicable law may be deemed to be interest with respect to this lending
transaction, for the purpose of any applicable law that may limit the maximum
amount of interest to be charged with respect to this lending transaction,
shall be payable by Borrower as, and shall be deemed to be, additional interest
and for such purposes only, the agreed upon and "contracted for rate of
interest" of this lending transaction shall be deemed to be increased by the
rate of interest resulting from the inclusion of the Additional Sums.

     It is the intent of the parties to comply with the usury laws of the State
of Arizona (the "Applicable Usury Law").  Accordingly, it is agreed that
notwithstanding any provisions to the contrary in


                                       3
<PAGE>   4
this Agreement, or in any of the documents securing payment hereof or otherwise
relating hereto, in no event shall this Agreement or such documents require the
payment or permit the collection of interest in excess of the maximum contract
rate permitted by the Applicable Usury Law (the "Maximum Interest Rate"). In
the event (a) any such excess of interest otherwise would be contracted for,
charged or received from Borrower or otherwise in connection with the loan
evidenced hereby, (b) the maturity of the Obligations is accelerated in whole
or in part, or (c) all or part of the Obligations shall be prepaid, so that
under any of such circumstances the amount of interest contracted for, shared
or received in connection with the loan evidenced hereby, would exceed the
Maximum Interest Rate, then in any such event (1) the provisions of this
paragraph shall govern and control, (2) neither Borrower nor any other person
or entity now or hereafter liable for the payment of the Obligations shall be
obligated to pay the amount of such interest to the extent that it is in excess
of the Maximum Interest Rate, (3) any such excess which may have been collected
shall be either applied as a credit against the then unpaid principal amount of
the Obligations or refunded to Borrower, at FINOVA's option, and (4) the
effective rate of interest shall be automatically reduced to the Maximum
Interest Rate. It is further agreed, without limiting the generality of the
foregoing, that to the extent permitted by the Applicable Usury Law; (x) all
calculations of interest which are made for the purpose of determining whether
such rate would exceed the Maximum Interest Rate shall be made by amortizing,
prorating, allocating and spreading during the period of the full stated term
of the loan evidenced hereby, all interest at any time contracted for, charged
or received from Borrower or otherwise in connection with such loan; and (y) in
the event that the effective rate of interest on the loan should at any time
exceed the Maximum Interest Rate, such excess interest that would otherwise
have been collected had there been no ceiling imposed by the Applicable Usury
Law shall be paid to FINOVA from time to time, if and when the effective
interest rate on the loan otherwise falls below the Maximum Interest Rate, to
the extent that interest paid to the date of calculation does not exceed the
Maximum Interest Rate, until the entire amount of interest which would
otherwise have been collected had there been no ceiling imposed by the
Applicable Usury Law has been paid in full. Borrower further agrees that should
the Maximum Interest Rate be increased at any time hereafter because of a
change in the Applicable Usury Law, then to the extent not prohibited by the
Applicable Usury Law, such increases shall apply to all indebtedness evidenced
hereby regardless of when incurred; but, again to the extent not prohibited by
the Applicable Usury Law, should the Maximum Interest Rate be decreased because
of a change in the Applicable Usury Law, such decreases shall not apply to the
indebtedness evidenced hereby regardless of when incurred.

4        COLLATERAL.

4.1      Security Interest in the Collateral. To secure the payment and
performance of the Obligations when due, Borrower hereby grants to FINOVA a
security interest in all of Borrower's now owned or hereafter acquired or
arising Inventory, Equipment, Receivables, and General Intangibles, including,
without limitation, all of Borrower's deposit accounts, money, any and all
property now or at any time hereafter in FINOVA's possession (including claims
and credit balances), and all proceeds (including proceeds of any insurance
policies, proceeds of proceeds and claims against third parties), all products
and all books and records related to any of the foregoing (all of the
foregoing, together with all other property in which FINOVA may be granted a
lien or security interest, is referred to herein, collectively, as the
"Collateral").

4.2      Perfection and Protection of Security Interest. Borrower shall, at its
expense, take all actions requested by FINOVA at any time to perfect, maintain,
protect and enforce FINOVA's security interest and other rights in the
Collateral and the priority thereof from time to time, including, without
limitation, (i) executing and filing financing or continuation statements and
amendments thereof in form and substance satisfactory to FINOVA, (ii) if
Borrower hereafter acquires and maintains Inventory, maintaining a perpetual
inventory and complete and accurate stock records, (iii) if Borrower hereafter
acquires and maintains Inventory, delivering to FINOVA warehouse receipts
covering any portion of the Collateral located in warehouses and for which
warehouse receipts are issued, and transferring Inventory to warehouses
designated by FINOVA, (iv) placing notations on Borrower's books of account to
disclose FINOVA's security interest therein, and (v) delivering to FINOVA all
letters of credit on which Borrower is named beneficiary. FINOVA may file,
without Borrower's signature, one or more financing statements disclosing
FINOVA's security





                                       4
<PAGE>   5
interest under this Agreement. Borrower agrees that a carbon, photographic,
photostatic or other reproduction of this Agreement or of a financing statement
is sufficient as a financing statement. If any Collateral is at any time in the
possession or control of any warehouseman, bailee or any of Borrower's agents
or processors, Borrower shall notify such Person of FINOVA's security interest
in such Collateral and, upon FINOVA's request, instruct them to hold all such
Collateral for FINOVA's account subject to FINOVA's instructions. From time to
time, Borrower shall, upon FINOVA's request, execute and deliver confirmatory
written instruments pledging the Collateral to FINOVA, but Borrower's failure
to do so shall not affect or limit FINOVA's security interest or other rights
in and to the Collateral. Until the Obligations have been fully satisfied and
FINOVA's obligation to make further advances hereunder has terminated, FINOVA's
security interest in the Collateral shall continue in full force and effect.

4.3      Preservation of Collateral. FINOVA may, in its sole discretion, at any
time discharge any lien or encumbrance on the Collateral or bond the same, pay
any insurance, maintain guards, pay any service bureau, obtain any record or
take any other action to preserve the Collateral and charge the cost thereof to
Borrower's loan account as an Obligation.

4.4      Insurance. Borrower will maintain and deliver evidence to FINOVA of
such insurance as is required by FINOVA, written by insurers, in amounts, and
with lender's loss payee and other endorsements, satisfactory to FINOVA. All
premiums with respect to such insurance shall be paid by Borrower as and when
due. Accurate and complete copies of the policies shall be delivered by
Borrower to FINOVA. If Borrower fails to comply with this Section, FINOVA may
(but shall not be required to) procure such insurance at Borrower's expense and
charge the cost thereof to Borrower's loan account as an Obligation.

5        EXAMINATION OF RECORDS; FINANCIAL REPORTING.

5.1      Examinations. FINOVA shall at all reasonable times have full access to
and the right to examine, audit, make abstracts and copies from and inspect
Borrower's records, files, books of account and all other documents,
instruments and agreements relating to the Collateral and the right to check,
test and appraise the Collateral. Borrower shall deliver to FINOVA any
instrument necessary for FINOVA to obtain records from any service bureau
maintaining records for Borrower. All instruments and certificates prepared by
Borrower showing the value of any of the Collateral shall be accompanied, upon
FINOVA's request, by copies of related purchase orders and invoices. FINOVA
may, at any time after the occurrence of an Event of Default, copy Borrower's
books and records (including removing such books and records from Borrower's
premises if necessary for copying) or require Borrower to deliver copies of its
books and records to FINOVA.  FINOVA may, without expense to FINOVA, use such
of Borrower's personnel, supplies and premises as may be reasonably necessary
for maintaining or enforcing FINOVA's security interest.

5.2      Reporting Requirements. Borrower shall furnish FINOVA, upon request,
such information and statements as FINOVA shall request from time to time
regarding Borrower's business affairs, financial condition and the results of
its operations. Without limiting the generality of the foregoing, Borrower
shall provide FINOVA with: (i) copies of sales journals, cash receipt journals,
deposit slips and FINOVA's standard form collateral and loan report, daily;
(ii) upon FINOVA's request, copies of invoices, customer statements and credit
memoranda issued, remittance advices and reports; (iii) on or prior to the date
set forth on the Schedule, monthly agings and reconciliations of Receivables,
payables reports, and unaudited financial statements with respect to the prior

principles, consistently applied; (iv) within ten (10) days after the end of
each month, a report indicating the location of each of Borrower's drilling
rigs, in form and substance acceptable to FINOVA; (v) audited annual

with generally accepted accounting principles applied on a basis consistent
with the most recent Prepared Financials provided to FINOVA by Borrower,
including balance sheets, income and cash flow statements, accompanied by the
unqualified report thereon of independent certified public accountants
acceptable to FINOVA, as soon as available, and in any event, within ninety
(90) days after the end of each of Borrower's fiscal years; and (vi) such
certificates relating to the foregoing as FINOVA may request, including,
without limitation, a monthly certificate from the president and the chief

financial officer of Borrower showing Borrower's compliance with each of the
financial covenants set forth in this Agreement, and stating whether any Event
of Default has occurred or event which, with giving of notice or the passage of
time, or both, would constitute an Event of Default, and if so, the steps being
taken to prevent or cure such Event of Default.

6        COLLATERAL REPORTING.

6.1      Invoices. Borrower shall not re-date any invoice from the original
date thereof or provide services on extended terms beyond those customary in
Borrower's industry, or otherwise extend or modify the term of any Receivable.
If Borrower becomes aware of any matter affecting any Receivable, including
information affecting the credit of the account debtor thereon, Borrower shall
promptly notify FINOVA in writing.

6.2      Instruments. In the event any Receivable is or becomes evidenced by a
promissory note, trade acceptance or any other instrument for the payment of
money, Borrower shall immediately deliver such instrument to FINOVA
appropriately endorsed to FINOVA and, regardless of the form of any
presentment, demand, notice of dishonor, protest or notice of protest with
respect thereto, Borrower shall remain liable thereon until such instrument is
paid in full. FINOVA shall not transfer any such instrument prior to the
occurrence of an Event of Default; provided, however, a transfer of any such
instrument shall not be deemed to have occurred hereunder solely as a result of
a sale of FINOVA or FINOVA's transfer of the Loans in an asset securitization
transaction.

7        PRINCIPAL PAYMENTS; PROCEEDS OF COLLATERAL.

7.1      Principal Payments. Except as otherwise provided in the Term Loan
Note, that portion of the Obligations consisting of principal payable on
account of Receivable Loans shall be payable by Borrower to FINOVA immediately
upon the earliest of (i) the receipt by FINOVA or Borrower of any proceeds of
any of the Collateral, to the extent of said proceeds, (ii) the occurrence of
an Event of Default in consequence of which FINOVA elects to accelerate the
maturity and payment of such loans, or (iii) any termination of this Agreement
pursuant to Section 16 hereof; provided, however, that any Overline shall be
payable on demand pursuant to the provisions of Section 1.3 hereof.

7.2      Collections. Until FINOVA notifies Borrower to the contrary, Borrower
may make collection of all Receivables for FINOVA and shall receive all
payments as trustee of FINOVA and immediately deliver all payments to FINOVA in
their original form as set forth below, duly endorsed in blank. FINOVA or its
designee may, at any time, notify account debtors that the Receivables have
been assigned to FINOVA and of FINOVA's security interest therein, and may
collect the Receivables directly and charge the collection costs and expenses
to Borrower's loan account. Borrower agrees that, in computing the charges
under this Agreement, all items of payment shall be deemed applied by FINOVA on
account of the Obligations two (2) Business Days after receipt by FINOVA of
good funds which have been finally credited to FINOVA's account, whether such
funds are received directly from Borrower or from the Blocked Account bank or
the Dominion Account bank, pursuant to Section 7.3 hereof, and this provision
shall apply regardless of the amount of the Obligations outstanding or whether
any Obligations are outstanding. FINOVA is not, however, required to credit
Borrower's account for the amount of any item of payment which is
unsatisfactory to FINOVA in its sole discretion and FINOVA may charge
Borrower's loan account for the amount of any item of payment which is returned
to FINOVA unpaid.

7.3      Establishment of a Lockbox Account or Dominion Account. All proceeds
of Collateral shall, at the direction of FINOVA, be deposited by Borrower into
a lockbox account, or such other "blocked account" as FINOVA may require (each,
a "Blocked Account") pursuant to an arrangement with such bank as may be
selected by Borrower and be acceptable to FINOVA.  Borrower shall issue to any
such bank an irrevocable letter of instruction directing said bank to transfer
such funds so deposited to FINOVA, either to any account maintained by FINOVA
at said bank or by wire transfer to appropriate account(s) of FINOVA. All funds
deposited in a Blocked Account shall immediately become the sole property of
FINOVA and Borrower shall obtain the agreement by such bank to waive any offset
rights against the funds so deposited. FINOVA assumes no responsibility for any
Blocked Account arrangement, including without limitation, any claim of accord
and satisfaction or release with respect to deposits accepted by any bank
thereunder. Alternatively, FINOVA may establish depository accounts in the name
of FINOVA at a bank or banks





                                       6
<PAGE>   7
for the deposit of such funds (each, a "Dominion Account") and Borrower shall
deposit all proceeds of Receivables and, to the extent permitted herein,
Equipment or cause same to be deposited, in kind, in such Dominion Accounts of
FINOVA in lieu of depositing same to Blocked Accounts.

7.4      Payments Without Deductions. Borrower shall pay principal, interest,
and all other amounts payable hereunder, or under any related agreement,
without any deduction whatsoever, including, but not limited to, any deduction
for any setoff or counterclaim.

7.5      Collection Days Upon Repayment. In the event Borrower repays the
Obligations in full at any time hereafter, such payment in full shall be
credited (conditioned upon final collection) to Borrower's loan account two (2)
Business Days after FINOVA's receipt thereof.

7.6      Monthly Accountings. FINOVA shall provide Borrower monthly with an
account of advances, charges, expenses and payments made pursuant to this
Agreement. Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications of
payments made and corrections of errors discovered by FINOVA), unless Borrower
notifies FINOVA in writing to the contrary within sixty (60) days after each
account is rendered, describing the nature of any alleged errors or admissions.

8        POWER OF ATTORNEY.

Borrower appoints FINOVA and its designees as Borrower's attorney, with the
power to endorse Borrower's name on any checks, notes, acceptances, money
orders or other forms of payment or security that come into FINOVA's
possession; to sign Borrower's name on any invoice relating to any Receivable,
on drafts against customers, on assignments of Receivables, on notices of
assignment, financing statements and other public records, on verifications of
accounts and on notices to customers or account debtors; to send requests for
verification of Receivables to customers or account debtors; after the
occurrence of any Event of Default, to notify the post office authorities to
change the address for delivery of Borrower's mail to an address designated by
FINOVA and to open and dispose of all mail addressed to Borrower; and to do all
other things FINOVA deems necessary or desirable to carry out the terms of this
Agreement.  FINOVA is authorized to act as Borrower's attorney only to the
extent that such acts are in accordance with the terms of this Agreement and
necessary to enforce FINOVA's rights under this Agreement. Borrower hereby
ratifies and approves all acts of such attorney. Neither FINOVA nor any of its
designees shall be liable for any acts or omissions nor for any error of
judgment or mistake of fact or law while acting as Borrower's attorney. This
power, being coupled with an interest, is irrevocable until the Obligations
have been fully satisfied and FINOVA's obligation to provide loans hereunder
shall have terminated.

9        RECEIVABLES.

9.1      Eligibility. Borrower represents and warrants that each Receivable
covers and shall cover a bona fide sale or lease and delivery by it of goods or
the rendition by it of services in the ordinary course of its business, and
shall be for a liquidated amount and FINOVA's security interest shall not be
subject to any offset, deduction, counterclaim, rights of return or
cancellation, lien or other condition. If any representation or warranty herein
is breached as to any Receivable or any Receivable ceases to be an Eligible
Receivable for any reason other than payment thereof, then FINOVA may, in
addition to its other rights hereunder, designate any and all Receivables owing
by that account debtor as not Eligible Receivables; provided, that FINOVA shall
in any such event retain its security interest in all Receivables, whether or
not Eligible Receivables, until the Obligations have been fully satisfied and
FINOVA's obligation to provide loans hereunder has terminated.

9.2      Disputes. Borrower shall notify FINOVA promptly of all disputes or
claims and settle or adjust such disputes or claims at no expense to FINOVA,
but no discount, credit or allowance shall be granted to any account debtor and
no returns of merchandise shall be accepted by Borrower without FINOVA's
consent, except for discounts, credits and allowances made or given in the
ordinary course of Borrower's business. FINOVA may, at any time after the
occurrence of an Event of Default, settle or adjust disputes or claims directly
with account debtors for amounts and upon terms which FINOVA considers
advisable in its reasonable credit judgment and, in all cases, FINOVA shall
credit Borrower's loan account with only the net amounts received by FINOVA in
payment of any Receivables.




                                       7

10   EQUIPMENT.

Borrower shall keep and maintain the Equipment in good operating condition and
repair and make all necessary replacements thereto to maintain and preserve the

item of Equipment to become a fixture (other than a trade fixture) to real
estate or an accession to other property.

11       OTHER LIENS; NO DISPOSITION OF COLLATERAL.

Borrower represents, warrants and covenants that (a) all Collateral is and
shall continue to be owned by it free and clear of all liens, claims and
encumbrances whatsoever (except for FINOVA's security interest, Permitted
Encumbrances, purchase-money security interests granted by Borrower in
connection with its purchase of new Equipment consistent with the Capital
Expenditures and Indebtedness covenants set forth in this Agreement, and such
other liens, claims and encumbrances as may be permitted by FINOVA in its sole
discretion from time to time in writing), and (b) Borrower shall not, without
FINOVA's prior written approval, sell, encumber or dispose of or permit the
sale, encumbrance or disposal of any Collateral or any interest of Borrower
therein, except for the sale of used Equipment in the ordinary course of
Borrower's business, provided that (i) all such sales during any year of the
term of this Agreement shall not involve Equipment having a fair market value
in excess of $100,000, (ii) Borrower shall remit to FINOVA the proceeds of all
such sales, and FINOVA shall apply such proceed to reduce Borrower's
outstanding Receivable Loans, and (iii) Borrower shall purchase replacement
Equipment acceptable to FINOVA for all such sold Equipment within sixty (60)
days after the sale of such Equipment. In the event FINOVA gives any such prior
written approval, the same may be conditioned on the sale price being equal to,
or greater than, an amount acceptable to FINOVA. The proceeds of any such sales
shall be remitted To FINOVA pursuant to this Agreement for application to the
Obligations.

may have relating to Borrower or Borrower's business. To the extent that FINOVA

thereafter be released from such assigned obligations to Borrower and such
assignment shall effect a novation between Borrower and such third party.

19.8     Survival. All of the representations and warranties of Borrower
contained in this Agreement shall survive the execution, delivery and
acceptance of this Agreement by the parties. No termination of this Agreement
or of any guaranty of the Obligations shall affect or impair the powers,
obligations, duties, rights, representations, warranties or liabilities of the
parties hereto and all shall survive any such termination.

19.9     Evidence of Obligations. Each Obligation may, in FINOVA's discretion,
be evidenced by notes or other instruments issued or made by Borrower to
FINOVA. If not so evidenced, such Obligation shall be evidenced solely by
entries upon FINOVA's books and records.

19.10     Collateral Security. The Obligations shall constitute one loan
secured by the Collateral. FINOVA may, in its sole discretion, (i) exchange,
enforce, waive or release any of the Collateral, (ii) apply Collateral and
direct the order or manner of sale thereof as it may determine, and (iii)
settle, compromise, collect or otherwise liquidate any Collateral in any manner
without affecting its right to take any other action with respect to any other
Collateral.

19.11     Application of Collateral. FINOVA shall have the continuing and
exclusive right to apply or reverse and re-apply any and all payments to any
portion of the Obligations in such order and manner as FINOVA shall determine
in its sole discretion. To the extent that Borrower makes a payment or FINOVA
receives any payment or proceeds of the Collateral for Borrower's benefit which
is subsequently invalidated, declared to be fraudulent or preferential, set
aside or required to be repaid to a trustee, debtor in possession, receiver or
any other party under any bankruptcy law, common law or equitable cause, then,
to such extent, the Obligations or part thereof intended to be satisfied shall
be revived and continue as if such payment or proceeds had not been received by
FINOVA.

19.12     Loan Requests. Each oral or written request for a loan by any Person
who purports to be any Employee, officer or authorized agent of Borrower shall
be made to FINOVA on or prior to 11:00 a.m., Chicago time, on the Business Day
on which the proceeds thereof are requested to be paid to Borrower and shall be
conclusively presumed to be made by a Person authorized by Borrower to do so
and the crediting of a loan to Borrower's operating account shall conclusively
establish Borrower's obligation to repay such loan. Unless and until Borrower
otherwise directs FINOVA in writing, all loans shall be wired to Borrower's
operating account set forth on the Schedule.

19.13     Notices. Any notice required hereunder shall be in writing and
addressed to the Borrower and FINOVA at their addresses set forth at the
beginning of this Agreement. Notices hereunder shall be deemed received on the
earlier of receipt, whether by mail, personal delivery, facsimile, or
otherwise, or upon deposit in the United States mail, postage prepaid.

19.14     Brokerage Fees. Borrower represents and warrants to FINOVA that, with
respect to the financing transaction herein contemplated, no Person other than
Capital Investment Group is entitled to any brokerage fee or other commission
and Borrower agrees to indemnify and hold FINOVA harmless against any and all
such claims.

19.15     Disclosure. No representation or warranty made by Borrower in this
Agreement, or in any financial statement, report, certificate or any other
document furnished in connection herewith contains any untrue statement of a
material fact or omits to state any material fact necessary to make the
statements herein or therein not misleading. There is no fact known to Borrower
which Borrower has not disclosed to FINOVA in writing with respect to the
transactions contemplated by this Agreement which materially and adversely
affects the business, assets, operations, prospects or condition (financial or
otherwise), of Borrower.

19.16     Publicity. FINOVA is hereby authorized to issue appropriate press
releases and to cause a tombstone to be published announcing the consummation
of this transaction and the aggregate amount thereof.

19.17     Captions. The Section titles contained in this Agreement are without
substantive meaning and are not part of this Agreement.

19.18     Injunctive Relief. Borrower recognizes that, in the event Borrower
fails to perform, observe or discharge any of its Obligations under this
Agreement, any remedy at law may prove to be inadequate relief to FINOVA.
Therefore, FINOVA, if it so requests, shall be entitled to temporary and
permanent injunctive relief in any such case without the necessity of proving
actual damages.

19.19    Counterparts. This Agreement may be executed in one or more
counterparts, each of which taken together shall constitute one and the same
instrument.

19.20    Construction. The parties acknowledge that each party and its counsel
have reviewed this Agreement and that the normal rule of construction to the
effect that any ambiguities are to be resolved against the drafting party shall
not be employed in the interpretation of this Agreement or any amendments or
exhibits hereto.

19.21    Time of Essence. Time is of the essence for the performance by
Borrower of the Obligations set forth in this Agreement.

19.22    Limitation of Actions. Borrower agrees that any claim or cause of
action by Borrower against FINOVA, or any of FINOVA's directors, officers,
employees, agents, accountants or attorneys, based upon, arising from, or
relating to this Agreement, or any other present or future agreement, or any
other transaction contemplated hereby or thereby or relating hereto or thereto,
or any other matter, cause or thing whatsoever, whether or not relating hereto
or thereto, occurred, done, omitted or suffered to be done by FINOVA, or by
FINOVA's directors, officers, employees, agents, accountants or attorneys,
whether sounding in contract or in tort or otherwise, shall be barred unless
asserted by Borrower by the commencement of an action or proceeding in a court
of competent jurisdiction by the filing of a complaint within one year after
the first act, occurrence or omission upon which such claim or cause of action,
or any part thereof, is based and service of a summons and complaint on an
officer of FINOVA or any other person authorized to accept service of process
on behalf of FINOVA, within 90 days thereafter. Borrower agrees that such
one-year period of time is a reasonable and sufficient time for Borrower to
investigate and act upon any such claim or cause of action. The one-year period
provided herein shall not be waived, tolled, or extended except by a specific
written agreement of FINOVA. This provision shall survive any termination of
this Loan Agreement or any other agreement.

19.23    Liability. Neither FINOVA nor any FINOVA Affiliate shall be liable
for any indirect, special, incidental or consequential damages in connection
with any breach of contract, tort or other wrong relating to this Agreement or
the Obligations or the establishment, administration or collection thereof
(including without limitation damages for loss of profits, business
interruption, or the like), whether such damages are foreseeable or
unforeseeable, even if FINOVA has been advised of the possibility of such
damages. Neither FINOVA, nor any FINOVA Affiliate shall be liable for any
claims, demands, losses or damages, of any kind whatsoever, made, claimed,
incurred or suffered by the Borrower through the ordinary negligence of FINOVA,
or any FINOVA Affiliate. "FINOVA Affiliate" shall mean FINOVA's directors,
officers, employees, agents, attorneys or other person or entity affiliated
with or representing FINOVA.

19.24    Notice of Breach by FINOVA. Borrower agrees to give FINOVA written
notice of (i) any action or inaction by FINOVA or any attorney of FINOVA in
connection with any Loan Documents that may be actionable against FINOVA or any
attorney of FINOVA or (ii) any defense to the payment of the Obligations for
any reason, including, but not limited to, commission of a tort or violation of
any contractual duty or duty implied by law. Borrower agrees that unless such
notice is fully given as promptly as possible (and in any event within ninety
(90) days) after Borrower has knowledge, or with the exercise of reasonable
diligence should have had knowledge, of any such action, inaction or defense,
Borrower shall not assert, and Borrower shall be deemed to have waived, any
claim or defense arising therefrom.

19.25    MUTUAL WAIVER OF RIGHT TO JURY TRIAL. FINOVA AND BORROWER EACH HEREBY
WAIVES THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON,
ARISING OUT OF, OR IN ANY WAY RELATING TO: (i) THIS AGREEMENT; (ii) ANY OTHER

applicable account on the date that good funds were received by FINOVA (either

LOANS (SECTION 1.2):

outstanding principal amount not to exceed the lesser of (a) or (b) below:

              (a) $500,000, or

              (b) 80% of the net amount of Eligible Receivables.

<PAGE>   2
       B. TERM LOAN: A term loan against the value of Borrower's machinery
and equipment in the original principal amount of One Million Two Hundred Fifty
Thousand Dollars ($1,250,000) (the "Term Loan"), which shall be evidenced by
and payable in accordance with the terms of the Term Loan Note.

CONDITIONS PRECEDENT (SECTION 2.1):

       The obligation of FINOVA to make the initial advance hereunder is
subject to the fulfillment, to the satisfaction of FINOVA and its counsel, of
each of the following conditions, in addition to the conditions set forth in
Sections 2.1 and 2.2 above: (a) Borrower shall have excess borrowing
availability under the Receivable Loans facility of not less than $150,000,
after giving effect to the initial advance hereunder and after giving effect to
payment in full of all of Borrower's (i) accounts payable outstanding for sixty
(60) days or more from their written due date or for more than ninety (90) days
from their invoice date, and (ii) all book overdrafts; and (b) there shall have
been no material adverse change in the business, operations, profits or
prospects of Borrower, or in the condition of the assets of Borrower, between
January 31, 1996 and the date hereof. Borrower shall cause the conditions
precedent set forth in Section 2.1 of this Agreement and set forth above in
this Schedule to be satisfied on or before the Closing Date.

INTEREST AND FEES (SECTION 3.1):

       Interest. Borrower shall pay FINOVA interest on the daily outstanding
balance of Borrower's Receivable Loans account at a per annum rate of two and
three-quarters (2.75) percentage points in excess of the rate of interest
announced publicly by Citibank, N.A., from time to time as its "base rate" (or
any successor thereto), which may not be such institution's lowest rate (the
"Base Rate"). The interest rate chargeable hereunder in respect of the
Receivable Loans shall be increased or decreased, as the case may be, without
notice or demand of any kind, upon the announcement of any change in the Base
Rate. Each change in the Base Rate shall be effective hereunder on the first
day following the announcement of such change, provided, that a cumulative
change of less than one-fourth of one percent (0.25%) shall not be considered.
Interest charges and all other fees and charges herein shall be computed on the
basis of a year of 360 days and actual days elapsed and shall be payable to
FINOVA in arrears on the first day of each month.  Borrower shall pay FINOVA
interest on the unpaid principal balance of the Term Loan as set forth in the
Term Loan Note.

       Minimum Interest Charge. With respect to each calendar month or portion
thereof during the term of this Agreement (excluding the calendar month in
which this Agreement is executed), Borrower shall also pay FINOVA, on the first
day of the next month, as a minimum charge, the amount by which accrued
interest pursuant to the section above for such month or portion thereof is
less than $5,000 (the "Minimum Interest Charge"). Notwithstanding the
occurrence of any Event of Default hereunder or termination of this Agreement
by FINOVA as a result thereof, the Minimum Interest Charge shall be paid by
Borrower for the unexpired portion of the Initial Term or any Renewal Term of
this Agreement.




                                     S-2
<PAGE>   3
       Closing Fee. At the closing of this transaction, Borrower shall pay to
FINOVA a closing fee in an amount equal to one percent (1.0%) of the Initial
Total Facility Amount, which shall be deemed fully earned at the time of
payment.

       Examination Fees. Borrower agrees to pay to FINOVA an examination fee in
the amount of Five Hundred Dollars ($500) per person per day in connection with
each audit or examination of Borrower performed by FINOVA prior to or after the
date hereof, provided that prior to the occurrence of an Event of Default
Borrower shall not be obligated to FINOVA for more than $8,000 plus
out-of-pocket costs in any year in connection with such audits or expenses.
Without limiting the generality of the foregoing, Borrower shall pay to FINOVA
an initial examination fee in an amount equal to $500 per person per day. Such
initial examination fee shall be deemed fully earned at the time of payment and
due and payable upon the closing of this transaction, and shall be deducted
from any good faith deposit paid by Borrower to FINOVA prior to the date of
this Agreement, or if such good faith deposit is insufficient to cover such
initial examination fee, Borrower shall pay such fee to FINOVA promptly
following Borrower's receipt of FINOVA's statement therefor.

reconciliations of Receivables within ten (10) days after the end of each

first-in, first-out basis at the lower of cost or market (in accordance with
generally accepted accounting principles) or such other inventory reports as
are reasonably requested by FINOVA, all within fifteen (15) days after the end
of each month.

4. Borrower shall provide FINOVA with monthly unaudited financial statements
within thirty (30) days after the end of each month.
