     Item 1.  BUSINESS

     General

          TMBR/Sharp Drilling,  Inc. (the "Company") was  incorporated under the
     laws of  Texas in  October, 1982  under the  name TMBR  Drilling, Inc.   In
     August, 1986, the Company changed its name to TMBR/Sharp Drilling, Inc.

          The principal executive  offices of  the Company are  located at  4607
     West  Industrial Blvd., Midland, Texas,  79703 and its  telephone number is
     (915) 699-5050.

          The  Company is engaged  in two lines  of business,  which include the
     domestic  onshore  contract  drilling    of  oil  and  gas  wells, and  the
     acquisition, exploration for, development, production  and sale of oil  and
     natural gas.

          The Company  provides domestic  onshore contract drilling  services to
     major  and independent  oil  and gas  companies.   The Company  focuses its
     operations in the Permian Basin of west  Texas and eastern New Mexico.   In
     addition to its drilling rigs,  the Company provides the crews and  most of
     the ancillary  equipment used in the  operation of its drilling  rigs.  Rig
     utilization for the fiscal year ended  March 31, 1998 was approximately 78%
     compared to 52% for the year ended March 31, 1997.

          The Company owns 17 drilling rigs, of which 2 were operating on behalf
     of the  Company for  its own account,  6 of which  were operating  for non-
     affiliated  oil producers, and 9 were "stacked" (non-operating) at June 22,
     1998.  All  of the Company's rigs are operational  and actively marketed in
     the  Permian  Basin of  west Texas  and eastern  New  Mexico.   The Company
     markets  its contract  drilling services  to both  major oil  companies and
     independent  oil producers.  The  depth capabilities of  the Company's rigs
     range from 8,500 feet to 30,000 feet.

          An onshore drilling rig consists of engines, drawworks, mast, pumps to
     circulate drilling fluids, blowout  preventers, the drillstring and related
     equipment.  The  size and type  of rig utilized  for each drilling  project
     depends  upon  the location  of  the  well, the  well  depth and  equipment
     requirements specified in the drilling contract, among other factors.

          The Company believes it has  established a reputation for reliability,
     high  quality equipment and  well-trained crews.   The  Company continually
     seeks to modify and upgrade  its equipment to maximize the  performance and
     capabilities of its drilling rig fleet, which the Company believes provides
     it with a competitive advantage.  The Company has the capability to design,
     repair  and modify its  drilling rig fleet  from its  principal support and
     storage facilities in  Midland, Texas,  and an additional  storage yard  in
     Odessa, Texas.

                                         -3-

          The  Company's  oil  and  gas exploration  and  production  operations
     complement  its onshore drilling operations.   These activities are focused
     in  the  mature producing  regions  in  the Permian  Basin.    Oil and  gas
     operations comprised  approximately 6%  of the  Company's revenues for  the
     fiscal year  ended March 31, 1998.   The Company's proved  reserves, all of
     which were proved developed producing, were approximately 919 MBOE (million
     barrels  of oil equivalent) and had a  present value of future net revenues
     of  approximately $4.7 million at  March 31, 1998.  At  March 31, 1998, the
     Company  owned interests in approximately 18,818 gross (2,464 net) acres of
     developed oil and gas  properties, and approximately 7,207 gross  (454 net)
     acres of undeveloped properties.

          The  Company  has  no   material  patents,  licenses,  franchises,  or
     concessions which it considers significant to its operations.

          The nature of the Company's business is such that it does not maintain
     or require a "backlog" of products, customer orders, or inventory.

          The Company's operations are  not subject to renegotiation  of profits
     or termination of contracts at the election of the federal government.

          The  Company has  not been  a party  to any  bankruptcy, receivership,
     reorganization, adjustment, or similar proceeding.

          Generally,  the  Company's business  activities  are  not seasonal  in
     nature.  However, weather conditions can hinder drilling activities.

          Major overhauls, repairs and general maintenance for the drilling rigs
     are  primarily conducted  at  the Company's  principal support  and storage
     facilities in Midland, Texas.   The Company emphasizes the  maintenance and
     periodic improvement of its  drilling equipment and believes that  its rigs
     are generally in good condition.  See "Item 2. Properties".

     Drilling Contracts

          The   Company's  drilling  contracts   are  usually  obtained  through
     competitive bidding or as  a result of direct negotiations  with customers.
     Drilling  contracts typically  obligate  the Company  to  pay all  expenses
     associated  with drilling an oil  or gas well,  including wages of drilling
     personnel, maintenance  expenses and  incidental purchases of  rig supplies
     and  equipment.   The  majority of  the  Company's contracts  are "footage"
     contracts with the remainder being "daywork" or "turnkey" contracts.  Under
     a footage  contract, the Company charges  an agreed price per  foot of hole
     drilled, whereas a day-work  contract permits the  Company to charge a  per
     diem fixed rate for each day the  rig is in operation.  A turnkey  contract
     specifies a total price  for drilling a well plus providing other services,
     materials or  equipment  which  are  typically the  responsibility  of  the
     operator under footage or daywork contracts.  Prices for all contracts vary
     depending on the  location, depth, duration,  complexity of the well  to be
     drilled, operating conditions  and other factors peculiar  to each proposed
     well.    Under  footage and  turnkey  contracts,  the  Company manages  the
     drilling operation and the type of equipment to be used, subject to certain
     customer specifications.   The Company also bears  the risk and expense  of
     mechanical malfunctions, equipment shortages, and other delays arising from
     problems caused in drilling a well.  Daywork contracts permit the  operator
     of  the well  to manage  drilling  operations and  to specify  the type  of
     equipment to be used.  Under daywork contracts, the Company generally bears
     none of the  risk due to time delays caused  by unforeseeable circumstances
     such as stuck  or broken drill pipe or blowouts.   Of the 8 rigs working at
     June  22, 1998,  5 were  subject to  daywork contracts,  2 were  subject to
     footage contracts, and one was subject to a turnkey contract.

          The Company's operations  are subject to many  hazards, including well
     blowouts and fires that could cause personal injury, suspension of drilling
     operations, damage to or  destruction of equipment and damage  to producing
     formations  and surrounding areas.   The Company believes  it is adequately
     insured for public liability and damage to the property of others resulting
     from its operations.

     Rig Utilization

          The Company's  contract drilling revenues depend  upon the utilization
     of its  drilling rigs  and the  contract rates  received  for its  drilling
     operations.   These  two factors  are affected  by a  number of  variables,
     including  competitive conditions in the drilling industry and the level of
     exploration  and development activity conducted by oil and gas producers at
     any given time.   The level of domestic  drilling activity has historically
     fluctuated and cannot be accurately  predicted because of numerous  factors
     affecting  the petroleum  industry, including  oil and  gas prices  and the

                                         -5-

     degree  of  government regulation  of  the  industry.    Contract  drilling
     revenues and  rig utilization rates for  the past five years  are set forth
     below.

          (a)  Of  the total  number of  rigs owned,  one was  owned only  for a
               portion of the fiscal year ended March 31, 1998.

     Customers

          During the fiscal  year ended March  31, 1998, the  Company drilled  a
     total of  157 wells for  approximately 29 customers.   The following  table
     sets  forth certain information with respect to the principal customers for
     the Company's contract drilling services during such period.

                                                Percent  of            Number of

     Rand Paulson Oil Company, Inc.                  9%                 12

          The loss  of any  one  or more  of the  above customers  could have  a
     material adverse effect on  the Company, depending upon the demand  for the
     Company's drilling  rigs at the time of such loss and the Company's ability
     to attract new customers.

     Competition

          The  Company encounters  substantial competition  from other  drilling
     contractors in its  contract drilling operations.   The Company's principal
     market areas of west Texas and eastern New Mexico are highly fragmented and
     competitive.  Companies compete  primarily on the basis of  contract rates,
     suitability and availability of equipment and crews, experience of drilling
     in  certain  areas,  and reputation.    The  Company  believes it  competes
     favorably  with respect to all of  these factors.  Competition is primarily
     on a well-by-well basis and may vary significantly at any particular  time.
     Drilling rigs  can be  moved  from one  region to  another  in response  to
     perceived  long-term changes  in  levels of  activity.   In  recent  years,
     competition within the  industry has been intense due to  the oversupply of
     rigs  which resulted  from the  rig overbuilding  during the  peak drilling
     years of 1980  and 1981, and the depressed demand  resulting from lower oil
     and gas prices and excess deliverability of natural gas.

     Employees

          At  June  5,  1998,   the  Company  had  45  salaried   employees  and
     approximately 182  hourly paid employees.  Employees of the Company are not
     covered by any collective  bargaining agreements and the Company  has never
     experienced a strike or work stoppage.   The Company considers its employee
     relations to be satisfactory.

     REGULATION

     Oil and Gas

          The Company's  operations are regulated  by certain federal  and state
     agencies.  In particular, oil and gas production and related operations are
     or have  been subject to price  controls, taxes and other  laws relating to
     the oil and gas industry.  The Company cannot predict how existing laws and
     regulations  may be interpreted  by enforcement agencies  or court rulings,
     whether additional laws and regulations will be adopted, or the effect such
     changes  may  have  on its  business,  financial  condition  or results  of
     operations.

          The  Company's  oil  and   gas  exploration,  production  and  related
     operations are  subject to extensive  rules and regulations  promulgated by
     federal,  state and local agencies.  Failure  to comply with such rules and
     regulations  can result in substantial penalties.  The regulatory burden on
     the oil and gas industry increases the Company's cost of doing business and
     affects  its  profitability.    Because  such  rules  and  regulations  are
     frequently amended or reinterpreted,  the Company is unable to  predict the
     future cost or impact of complying with such laws.

          The  State of Texas and many other states require permits for drilling
     operations,  drilling bonds  and reports  concerning operations  and impose
     other  requirements relating to the  exploration and production  of oil and
     gas.  Such states also have statutes or regulations addressing conservation
     matters, including provisions for the unitization or pooling of oil and gas
     properties, the establishment of  maximum rates of production from  oil and
     gas wells and the regulation  of spacing, plugging and abandonment  of such
     wells.

          Sales of gas by  the Company are not regulated and  are made at market
     prices.    However,  the  Federal  Energy  Regulatory  Commission  ("FERC")
     regulates interstate  and certain  intrastate gas transportation  rates and
     service  conditions,  which affect  the marketing  of  gas produced  by the
     Company,  as well as the revenues received by the Company for sales of such
     production.    Since the  mid-1980s, FERC  has issued  a series  of orders,
     culminating  in Order  Nos. 636,636-A  and 636-B  ("Order 636"),  that have
     significantly altered the marketing  and transportation of gas.   Order 636
     mandates  a  fundamental restructuring  of  interstate  pipeline sales  and
     transportation service, including the unbundling by interstate pipelines of
     the sales,  transportation, storage and  other components of  the city-gate
     sales services such pipelines previously performed.  One of FERC's purposes
     in issuing the orders was to  increase competition within all phases of the
     gas  industry.  Order 636  and subsequent FERC  orders issued in individual

                                         -7-




<PAGE> 8
     pipeline restructuring proceedings  have been the  subject of appeals,  the
     results of which have  generally been supportive of the  FERC's open-access
     policy.   In 1996, the  United States Court of Appeals  for the District of
     Columbia Circuit  largely upheld Order  No. 636,  et seq.   Because further
     review  of certain of  these orders  is still  possible, and  other appeals
     remain pending,  it is  difficult  to predict  the ultimate  impact of  the
     orders on the Company and its gas marketing efforts.   Generally, Order 636
     has  eliminated   or  substantially   reduced  the   interstate  pipelines'
     traditional  role as wholesalers  of gas,  and has  substantially increased
     competition and volatility  in gas markets.   While significant  regulatory
     uncertainty remains, Order 636 may ultimately enhance the Company's ability
     to market and transport its  gas, although it may also subject  the Company
     to greater competition.

          The sale of oil by the Company is not regulated and is made  at market
     prices.  The price the Company receives from the sale of oil is affected by
     the cost of transporting the product to market.  Effective as of January 1,
     1995,  FERC implemented  regulations  establishing an  indexing system  for
     transportation rates  for interstate  common carrier oil  pipelines, which,
     generally,  would  index  such  rates  to  inflation,  subject  to  certain
     conditions and limitations.   These regulations could increase the  cost of
     transporting  oil  by  interstate   pipelines,  although  the  most  recent
     adjustment  generally decreased  rates.   These regulations  have generally
     been approved  on judicial review.  The Company is not able to predict with
     certainty what  effect, if  any, these  regulations will  have on it,  but,
     other factors being equal, the regulations may, over time, tend to increase
     transportation costs or reduce wellhead prices for oil.

          The  Company  is required  to comply  with  various federal  and state
     regulations regarding plugging and abandonment of oil and gas wells.

     Environmental

          Various federal, state  and local laws  and regulations governing  the
     discharge of materials into  the environment, or otherwise relating  to the
     protection of  the  environment, health  and safety,  affect the  Company's
     operations  and  costs.    These  laws  and  regulations  sometimes require
     governmental  authorization before  certain activities,  limit or  prohibit
     other activities because of protected  areas or species, impose substantial
     liabilities for pollution related to Company  operations or properties, and
     provide  penalties  for  noncompliance.     In  particular,  the  Company's
     exploration and  production operations,  its activities in  connection with
     storage  and transportation of oil  and other liquid  hydrocarbons, and its
     use  of   facilities  for   treating,  processing  or   otherwise  handling
     hydrocarbons and related exploration and  production wastes are subject  to
     stringent  environmental  regulation.    As with  the  industry  generally,
     compliance  with  existing   and  anticipated  regulations  increases   the
     Company's overall cost  of business.   While these  regulations affect  the
     Company's capital expenditures and earnings, the Company believes that such
     regulations  do not affect its competitive position in the industry because
     its  competitors   are  similarly  affected   by  environmental  regulatory

                                         -8-

     programs.   Environmental  regulations  have historically  been subject  to
     frequent change and, therefore, the Company is unable to predict the future
     costs  or other future impacts  of environmental regulations  on its future
     operations.  A discharge  of hydrocarbons or hazardous substances  into the
     environment could subject the Company to substantial expense, including the
     cost to  comply with applicable regulations that  require a response to the
     discharge, such as containment or cleanup, claims by neighboring landowners
     or  other third  parties  for personal  injury,  property damage  or  their
     response costs and penalties assessed, or other claims sought by regulatory
     agencies for response cost or for natural resource damages.

          The following are examples of some environmental laws that potentially
     impact the Company and its operations.

          Water.  The Oil Pollution  Act ("OPA") was enacted in 1990  and amends
     provisions of the Federal Water Pollution Control Act of 1972 ("FWPCA") and
     other statutes as  they pertain to prevention of and  response to major oil
     spills.   The  OPA  subjects owners  of  facilities to  strict,  joint  and
     potentially  unlimited  liability  for  removal  costs  and  certain  other
     consequences of an oil spill, where such spill is into navigable waters, or
     along  shorelines.    In  the  event of  an  oil  spill  into  such waters,
     substantial liabilities could be imposed upon the Company.  States in which
     the  Company  operates have  also enacted  similar  laws.   Regulations are
     currently  being developed  under the OPA  and similar state  laws that may
     also impose additional regulatory burdens on the Company.

          The  FWPCA  imposes restrictions  and  strict  controls regarding  the
     discharge  of  produced waters,  other  oil and  gas  wastes,  any form  of
     pollutant, and, in some  instances, storm water runoff, into  waters of the
     United States.  The  FWPCA provides for civil, criminal  and administrative
     penalties  for any unauthorized discharges and, along with the OPA, imposes
     substantially potential liability for the costs of the removal, remediation
     or damages  resulting from an  unauthorized discharge.  State  laws for the
     control  of  water   pollution  also  provide   for  civil,  criminal   and
     administrative penalties  and liabilities  in the  case of  an unauthorized
     discharge into state waters.  The cost  of compliance with the OPA and  the
     FWPCA  have not historically been material to the Company's operations, but
     there can  be no assurance  that changes in  federal, state or  local water
     pollution control programs will not materially adversely effect the Company
     in  the future.  Although no assurances  can be given, the Company believes
     that  compliance with existing permits and  compliance with foreseeable new
     permit  requirements will  not  have  a  material  adverse  effect  on  the
     Company's financial condition or results of operations.

          Air  Emissions.  Amendments  to the Federal  Clean Air Act  enacted in
     late  1990 (the  "1990  CAA  Amendments")  require  or  will  require  most
     industrial operations in the United States to incur capital expenditures in
     order  to   meet  air   emissions  control   standards  developed   by  the
     Environmental  Protection Agency ("EPA")  and state environmental agencies.
     Although no assurances can be given, the Company believes implementation of
     the 1990  CAA Amendments will  not have  a material adverse  effect on  the
     Company's financial condition or results of operations.

          Solid Waste.   The Company  generates non-hazardous solid  wastes that
     are  subject to the requirements  of the Federal  Resource Conservation and
     Recovery Act  ("RCRA")  and comparable  state statutes.   The  EPA and  the
     states  in which  the  Company operates  are  considering the  adoption  of
     stricter disposal standards  for the type of non-hazardous wastes generated
     by the Company.  RCRA also governs the generation, management, and disposal
     of  hazardous wastes.   At present, the  Company is not  required to comply
     with a substantial portion  of the RCRA requirements because  the Company's
     operations generate minimal quantities of hazardous wastes.  However, it is
     anticipated that  additional wastes,  which could include  wastes currently
     generated  during  operations,  could  in  the   future  be  designated  as
     "hazardous  wastes".   Hazardous wastes  are subject  to more  rigorous and
     costly disposal and management  requirements than are non-hazardous wastes.
     Such   changes  in  the  regulations   may  result  in  additional  capital
     expenditures or operating expenses by the Company.

          Superfund.   The  Comprehensive Environmental  Response, Compensation,
     and Liability Act ("CERCLA"), also known as "Superfund", imposes liability,
     without  regard to fault  or the legality  of the original  act, on certain
     classes  of  persons  in  connection  with  the  release  of  a  "hazardous
     substance" into the environment.   These persons include the  current owner
     or operator of any site where a release historically occurred and companies
     that  disposed or  arranged for  the disposal  of the  hazardous substances
     found at the site.  CERCLA also authorizes the EPA and, in  some instances,
     third parties  to act in response  to threats to  the public health  or the
     environment and to seek to recover from the responsible classes  of persons
     the  costs they  incur.   In  the course  of its  ordinary operations,  the
     Company  may  have  managed  substances   that  may  fall  within  CERCLA's
     definition of  a "hazardous  substance".   the Company  may be  jointly and
     severally liable  under CERCLA  for all  or part of  the costs  required to
     clean up sites where the  Company disposed of or arranged for  the disposal
     of these substances.   This potential liability extends to  properties that
     the Company owned or operated, as  well as to properties owned and operated
     by others at which disposal of the Company's hazardous substances occurred.

          The Company  may also fall  into the category  of a "current  owner or
     operator".  The Company  currently owns or leases numerous  properties that
     for many years have been used for the exploration and production of oil and
     gas.  Although  the Company believes it has utilized operating and disposal
     practices that were  standard in the industry at the  time, hydrocarbons or
     other wastes  may have been  disposed of or released  by the Company  on or
     under the properties owned or leased by the Company.  In  addition, many of
     these  properties have been previously  owned or operated  by third parties
     who may have disposed of or released hydrocarbons or other  wastes at these
     properties.   Under CERCLA, and analogous state  laws, the Company could be
     subject to certain liabilities  and obligations, such as being  required to
     remove or  remediate previously disposed wastes  (including wastes disposed
     of  or released  by prior owners  or operators),  to clean  up contaminated
     property  (including  contaminated  groundwater)  or  to  perform  remedial
     plugging operations to prevent future contamination.

     OIL AND GAS OPERATIONS

          The  Company's  oil  and   gas  operations  involve  the  acquisition,
     exploration for, development and production of oil and natural gas.  During
     the fiscal year  ended March  31, 1998, the  Company's exploration  efforts
     were conducted in west Texas and eastern New Mexico.

          The Company is  actively investing in oil  and gas properties  for the
     purpose of  exploration, development and  production of  oil and gas.   The
     Company  acquires  or  participates  in  these  arrangements  as  a working
     interest owner and usually provides the contract drilling services for such
     ventures.

          Exploration for oil and natural gas requires substantial expenditures,
     especially for  exploration in more remote  areas.  As is  customary in the
     oil  and  gas industry,  the  drilling  of oil  and  gas  wells is  usually
     accomplished  through participation with other  third parties.   One of the
     parties  experienced with operations in  the area is  usually designated as
     the operator of the property and is responsible for the direct supervision,
     administration and accounting for  wells drilled and completed pursuant  to
     an operating agreement between  the parties.  The Company  typically serves
     as  operator  of  oil  and  gas  prospects  assembled  by the  Company  and
     participates  as  a  non-operating  working  interest  owner  in  prospects
     assembled  and  generated  by third  parties.    As  operator, the  Company
     supervises the drilling  and completion of  wells and production  therefrom
     and the further  development of surrounding properties.  The  operator of a
     well has  significant  control over  its  location and  the timing  of  its
     drilling.  In  addition, the operator  of a well  receives fees from  other
     working interest owners as reimbursement for the general and administrative
     expenses  attendant to  the operation  of  the wells.    The operator  will
     normally receive revenues and pay expenses equal to more than its ownership
     interest in the wells, and then must remit or collect all  but its share to
     or from the other respective participants in the well.  At June 5, 1998 the
     Company was operator of 19 wells.

     Oil and Gas Reserves

          Information  concerning the  Company's  estimated proved  oil and  gas
     reserves is included  in Note  (9) to the  Company's financial  statements.
     See "Item 8 - Financial Statements and Supplementary Data".

          The  reserve  information is  only an  estimate.   There  are numerous
     uncertainties  inherent  in estimating  oil  and  gas  reserves  and  their
     estimated values, including many factors beyond the control of the Company.
     Reserve  engineering  is a  subjective  process  of estimating  underground
     accumulations of  oil and natural gas  that cannot be measured  in an exact
     manner,  and the  accuracy of  any reserve  estimate is  a function  of the
     quality of available data and  of engineering and geological interpretation
     and  judgment.  As  a result, estimates of  different engineers often vary.
     In addition,  estimates of  reserves  are subject  to revision  due to  the
     results  of drilling, testing and production subsequent to the date of such

                                         -11-






<PAGE> 12
     estimates.   Accordingly,  reserve estimates are  often different  from the
     quantities of oil  and gas that are ultimately recovered.   The accuracy of
     such  estimates is  highly dependent  upon the  accuracy of  the underlying
     assumptions upon which they are based. 

          In  general,  the volume  of production  from  oil and  gas properties
     declines  as reserves  are  depleted.   Except  to the  extent  the Company
     acquires  properties  containing  proved reserves  or  conducts  successful
     exploration  and development activities,  or both, the  proved reserves of,
     and volumes of  production by,  the Company  will decline  as reserves  are
     produced.  The Company's future oil and gas production  is therefore highly
     dependent  upon its  level of  success in  acquiring or  finding additional
     reserves.

          The Company has no reserves outside the United States.

          No  major discovery or other  favorable or adverse  event has occurred
     since March  31, 1998 which is believed to have caused a significant change
     in the estimated proved oil and gas reserves of the Company.

          The Company's oil and  gas reserves and production are not  subject to
     any  long-term  supply or  similar agreements  with foreign  governments or
     authorities.

          The Company's estimate of reserves has not been filed with or included
     in reports  to any federal  agency other  than the Securities  and Exchange
     Commission.

     Productive Wells and Acreage

          The following  tables set forth the  gross and net productive  oil and
     gas wells and developed and undeveloped acreage  in which the Company owned
     a  working  interest as  of March  31, 1998.   Excluded  from the  table is
     acreage in which the  Company's interest is  limited to royalty or  similar
     interests.

          Generally,   the  terms  of  developed  oil  and  gas  leaseholds  are
     continuing and such leases  remain in force by  virtue of, and so  long as,
     production from lands under lease is  maintained.  Undeveloped oil and  gas
     leaseholds  are generally for  a primary term,  such as five  or ten years,
     subject  to maintenance with the payment of specified minimum delay rentals
     or extension by production.

          In addition to the  Company's developed and undeveloped  acreage shown
     above, on  September 5, 1995,  the Company entered  into a 10  year License
     Agreement  with the Government  of the Republic  of Palau and  the State of
     Kayangel which  will allow the Company  to explore for oil  and natural gas
     offshore.   The license covers  approximately 1.1 million  acres within the
     waters of  Palau.  Any exploration  activities in the license  area will be
     conducted  jointly with  other  third  parties  under a  carried  interest,
     farmout  or other  similar arrangements  which would  allow the  Company to
     retain  an  ownership  interest  without incurring  the  initial  costs  of
     exploration.

     --------------------------
     (1)  An exploratory well is  a well drilled to find and produce  oil or gas
          in  an unproved area,  to find a  new reservoir in  a field previously
          found  to be  productive of  oil or  gas in  another reservoir,  or to
          extend a known reservoir.

     (2)  A development well  is a well drilled within the proved  area of a oil
          or gas reservoir  to the depth of a stratigraphic  horizon known to be
          productive. 

          At June 22,  1998, the Company was participating in  the drilling of 2
     gross (.56 net)  exploratory well in  Reeves County, Texas and  Lea County,
     New Mexico.

          Substantially  all of  the equipment  used  in the  Company's drilling
     operations is owned by the Company; however, certain insignificant items of
     drilling equipment are leased or rented as needed as  such equipment either

          (1)  An EBO is one equivalent barrel of oil using the ratio of six Mcf
     of gas to one barrel of oil.


     Title to Properties

          As is  customary in  the oil  and  gas industry,  a preliminary  title
     examination is conducted at the  time oil or gas properties believed  to be
     suitable  for  drilling  are  acquired  by the  operator.    Prior  to  the
     commencement of operations, curative work determined to be appropriate as a
     result  of a title search is  performed with respect to significant defects
     before the operator  commences development.   Title examinations have  been
     performed with respect to  substantially all of the Company's  interests in
     its  producing  properties.    The  Company  believes  that  title  to  its
     properties is good  and defensible in  accordance with standards  generally
     acceptable in the oil and  gas industry, subject to such exceptions  which,
     in the  Company's opinion, are not so  material as to detract substantially
     from the value of such properties.  The Company's properties are subject to
     royalty, overriding  royalty, and other outstanding  interests customary in
     the  industry, and are  also subject to  burdens such as  liens incident to
     operating agreements,  current taxes  not yet due,  development obligations
     under  oil   and  gas  leases,   and  other  encumbrances,   easements  and
     restrictions.   The Company does not believe that any of these burdens will
     materially interfere with the use of its properties in the operation of the
     Company's business.

     Markets and Customers

          The Company  sells its oil and gas at the wellhead on an "as-produced"

                                         -15-






<PAGE> 16
     basis and does not refine petroleum products.  Other than normal production
     facilities, the  Company does  not  own an  interest  in any  bulk  storage
     facilities or  pipelines.   As is  customary in  the industry, the  Company
     sells  its production  in  any  one  area  to  relatively  few  purchasers,
     including  transmission companies  that have  pipelines near  the Company's
     producing  wells.   Gas purchase  contracts are  generally on  a short-term
     "spot  market" basis and usually contain provisions by which the prices and
     delivery quantities for future  deliveries will be determined.   During the
     year ended  March 31, 1998,  Titan Resources  I, Inc. and  Amoco Production
     Company  accounted  for approximately  16%  and 15%,  respectively,  of the
     Company's oil and gas revenues for such period.  The loss  of either one of
     these purchasers could cease or delay the Company's production and sale  of
     its oil and gas reserves  to the extent that alternative  purchasers having
     adequate gathering  facilities are not  found to  replace such  purchaser's
     volume of  oil or gas purchased.   However, in the  event of a  loss of any
     purchaser, the Company believes that, under present circumstances, it would
     be able to find other purchasers for its oil and gas production.

     Competition

          The Company encounters strong competition from major oil companies and
     independent producers and operators in acquiring  properties and leases for
     exploration  for oil  and gas.   Competition  is particularly  intense with
     respect to the  acquisition of  desirable undeveloped oil  and gas  leases.
     The principal competitive factors in the acquisition of undeveloped oil and
     gas leases include the staff and data necessary to acquire and develop such
     leases, as well as  the amount of consideration and terms offered.  Many of
     the Company's  competitors have financial resources,  staffs and facilities
     substantially  greater than  those  of  the  Company.    In  addition,  the
     producing and marketing of  natural gas and oil is affected  by a number of
     factors which  are beyond the control  of the Company, the  effect of which
     cannot be  accurately predicted.   Of significant  importance recently  has
     been  the domination  and  control of  oil  markets and  prices by  foreign
     producers.

          The  principal   raw  materials   and  resources  necessary   for  the
     exploration  and development of oil  and gas are  leasehold prospects under
     which  oil and gas  reserves may be  discovered, drilling  rigs and related
     equipment  to explore  for  such reserves  and  knowledgeable personnel  to
     conduct all phases of oil and gas operations.  The Company must compete for
     such  raw materials  and  resources  with  both  major  oil  companies  and
     independent operators,  and  the continued  availability, without  periodic
     interruption,  of such  materials and  resources to  the Company  cannot be
     assured.


     Item 2.  PROPERTIES

          In addition to its drilling rigs and related equipment and its oil and
     gas properties,  the Company owns a 31 acre tract of land in Midland, Texas
     on which  the Company's  executive offices  are  located and  on which  the

                                         -16-






<PAGE> 17
     principal  support  and  storage   facilities  for  its  contract  drilling
     operations are located.   Such  facilities include an  office building  and
     fabrication and maintenance shop.   The facility allows for open storage of
     drilling equipment and drill pipe.

          The Company also  owns a 78 acre tract of land in Odessa, Texas, which
     is presently being utilized as a secondary storage location.   From time to
     time, the Company's  rigs are stored and stacked in the  field at the rig's
     last location site.

          The  Company   owns  a  warehouse   and  yard  facility   situated  on
     approximately 4 acres in Midland, Texas.  This additional storage is  being
     used  to  complement  the existing  Midland  yard  facility.   The  Company
     believes that the support  and storage facilities for its drilling rigs and
     related equipment are more than adequate.


     Item 3.  LEGAL PROCEEDINGS

          In March,  1992, the Company was  notified by the Texas  Department of
     Insurance  that  the  Company's  former  workers'   compensation  insurance
     carriers,  Sir  Lloyd's  Insurance  Company  and  its  affiliate,  Standard
     Financial Indemnity Corporation ("SFIC"), had been placed in liquidation by
     order  of the 201st  District Court of  Travis County, Texas,  on March 12,
     1992 in  Cause No. 92-12765, The  State of Texas vs.  Sir Lloyd's Insurance
     Company and  Sir Insurance  Agency, Inc.,  and in  Cause No.  91-12766, The
     State of Texas vs. Standard Financial Indemnity Corporation.  Approximately
     two months before being  ordered into liquidation, SFIC requested  that the
     Company pay policy premiums in the approximate amount of $646,476.  On July
     22,  1993  the  special   deputy  receiver  of  SFIC  billed   the  Company
     approximately  $1,061,000  for  retrospective premiums,  but  adjusted  the
     amount to $854,153 on January 12, 1994.

          In November, 1995, the  Company was notified  that a lawsuit had  been
     filed  in Travis County, Texas styled Texas property and Casualty Insurance
     Guaranty Association  vs. TMBR/Sharp  Drilling, Inc. (Cause  No. 95-12318).
     The Texas  Property and Casualty Insurance  Guaranty Association ("Guaranty
     Association") was seeking a  recovery of past workers' compensation  claims
     advanced  by the  Guaranty  Association related  to  the Company's  workers
     compensation insurance program  with SFIC.   The  Guaranty Association  was
     seeking to recover a total of $803,057.11.

          On  September 9, 1997, the Company entered into a settlement agreement
     with the Guaranty  Association.  The Company agreed to  pay to the Guaranty
     Association  the  sum of  $375,000 in  full  satisfaction of  any liability
     relating the Company's workers compensation insurance program with SFIC and
     Sir  Lloyd's  Insurance Company  and the  lawsuit  brought by  the Guaranty
     Association.   The  Company  originally accrued  $854,153  relating to  the
     Guaranty  Association's  claim  for reimbursement.    As  a  result of  the
     settlement,  the Company  has eliminated  the accrual  of $854,153  and the
     difference  between the accrued amount and the settlement amount ($479,153)

                                         -17-






<PAGE> 18
     has been  recognized as  miscellaneous  income in  the Company's  financial
     statements.

          In  addition, the Company has entered into a settlement agreement with
     the  insurance agent that  represented the Company at  the time the workers
     compensation insurance policies  were purchased from Sir Lloyd's  and SFIC.
     The agent has paid  the Company the sum  of $180,000 in full  settlement of
     all  claims  and liabilities  relating to  SFIC  and Sir  Lloyd's Insurance
     Company.   This amount has been  recognized as miscellaneous income  in the
     Company's financial statements.

          The Company  provides for  its workers'  compensation claims  prior to
     September  1997 based upon the  most recent information  available from its
     insurance  carrier concerning  claims  and estimated  costs.   However,  in
     future  years  the  Company   may  receive  retroactive  adjustments,  both
     favorable and unfavorable, related to estimates of claim costs for previous
     years, which  may be material to  the Company's results of  operations.  No
     provision  for retroactive adjustments to claim costs is recorded until the
     Company  receives  notification from  its  insurance  carrier because  this
     amount, if any, cannot be estimated.   For claims incurred November 1993 to
     September  1997, the Company is generally responsible for the first $10,000
     ($100,000  prior to  November  1993)  in  claim  costs  for  each  workers'
     compensation injury.   Currently the Company is covered  by a fully insured
     workers compensation policy.

          The Company is a defendant in various lawsuits generally incidental to
     its business.  The Company does not believe that the ultimate resolution of
     such litigation will have  a significant effect on the  Company's financial
     position or results of operations.


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

          There  was no meeting  of security holders  of the Company  during the
     fourth quarter of the fiscal year ended March 31, 1998, and no matters were
     submitted to a vote of security holders during such period.

          The  transfer agent for the  Company's Common Stock  is American Stock
     Transfer & Trust Company, New York, New York.

          On February 13, 1997,  the Company privately placed 725,000  shares of
     its Common  Stock to eleven accredited  investors, at a per  share price of
     $11.00.   Rauscher Pierce  Refsnes, Inc. ("Rauscher")  served as  placement
     agent for the  offering.   The net proceeds  from the  sale of the  shares,
     approximately  $7.47 million,  were  used to  repay  all of  the  Company's
     outstanding bank debt (approximately $4.5 million) and  for general working
     capital  purposes.    As  consideration  for  serving  as  placement agent,
     Rauscher  received a 5%  cash commission (an aggregate  of $398,750), and a
     non-accountable expense allowance of  $25,000.  The Company also  issued to
     Rauscher, for nominal consideration, a five-year  stock purchase warrant to
     purchase 36,250 shares of the Company's  Common Stock at an exercise  price
     of  $13.20 per  share.   The Common  Stock  was sold  in reliance  upon the
     exemption from registration  under Section  4(2) of the  Securities Act  of
     1933, as amended (the "Act"), and Rule 506 of Regulation D under the Act.

          On June  8, 1998, the outstanding shares of the Company's Common Stock
     were held of record by approximately 3,218 stockholders.

              (a)  During fiscal years ended March 31, 1998,  1997 and 1996, 
                   the Company recognized a non-cash charge of approximately
                   $3,120,000,  $171,000 and  $2,624,000, respectively,  due 
                   to a writedown of the carrying value  of its  oil and gas
                   properties.   This charge is a result of the  adoption of 
                   Statement of Financial Accounting Standards No. 121 ("SFAS
                   121") "Accounting for  the Impairment of Long-Lived Assets  
                   and for Long-Lived Assets to  Be Disposed Of".  SFAS  121
                   requires the Company to assess the need for an  impairment 
                   of capitalized  costs of  oil and gas  properties on  a
                   property-by-property basis  in contrast  to the  Company's 
                   prior  policy of  evaluating the  undiscounted future  net
                   revenues of its oil and gas properties in total.  According 
                   to SFAS  121, if an  impairment is  indicated based on
                   undiscounted future  cash flows, then it  is recognized to  
                   the extent that net  capitalized costs exceed  discounted
                   future cash flows.

     statements are not guarantees  of future performance and actual  results or
     developments may  differ materially  from those projected  in the  forward-
     looking statements.  

     Overview

        Since 1982,  the principal business of the Company has been the contract
     drilling of domestic onshore oil and gas wells.  In 1987, the Company began
     acquiring oil and gas  properties and participating in the  exploration for
     and development of oil and gas reserves.

        Contract Drilling Operations

        Drilling  revenues from footage and  daywork contracts are recognized as
     work  is performed  utilizing the  percentage-of-completion method.   Costs
     under footage and daywork contracts  are recognized in the period they  are
     incurred.   The Company utilizes the completed contract method to recognize
     drilling revenues and  expenses relating  to turnkey  contracts.   Expected
     losses on all  in-process contracts are recognized  in the period  the loss
     can reasonably be determined.

        Drilling equipment is depreciated on a  units-of-production method based
     on the monthly  utilization of the equipment.   Drilling equipment which is
     not utilized during a month is depreciated using a minimum utilization rate
     of approximately  25%.   Estimated useful  lives range  from four to  eight
     years.  Other property and equipment is depreciated using the straight-line
     method of depreciation with estimated useful lives of three to seven years.

        The contract  drilling industry remains  highly competitive.   Recently,
     the demand for drilling rigs has  softened due to extremely weak oil prices
     and lower gas prices.  The Company believes it owns a sufficient  number of
     drilling rigs  to remain  competitive within its  areas of  operation.   In
     addition,  the Company believes it  competes favorably with  respect to the
     depth capabilities of its  rigs, the experience level of its personnel, its
     reputation  and  its relationship  with existing  customers.   However, the
     Company's  operating results will continue  to be directly  affected by the
     level of drilling activity in the Company's service areas.

        The  following table  sets  forth certain  information  relating to  the
     Company's contract drilling operations for the periods indicated:

                                                   Year Ended March 31,
                                                 1998       1997      1996

          Contract drilling expenses as
            a percent of drilling revenues        66.4%      76.8%      81.0%

          Rig utilization                         78.2%      51.6%      45.1%


        Oil and Gas Operations  

        The Company's oil and gas  producing activities are accounted  for using
     the successful  efforts  method of  accounting.   Accordingly, the  Company
     capitalizes  all costs incurred to  acquire oil and  gas properties (proved
     and  unproved),   all  development  costs,  and  the  costs  of  successful
     exploratory  wells.    The  costs of  unsuccessful  exploratory  wells  are
     expensed.  Geological and  geophysical costs, including seismic  costs, are
     charged to expense  when incurred.   In  cases where  the Company  provides
     contract drilling for oil and  gas properties in which it has  an ownership
     interest,  the Company's  proportionate share  of costs  is  capitalized as
     stated above,  net of  its   working-interest  share  of profits  from  the
     related drilling  contracts.  Capitalized costs  of undeveloped properties,
     which are  not depleted until  proved reserves  can be associated  with the
     properties,  are  periodically  reviewed  for possible  impairment.    Such
     unevaluated costs totaled  approximately $111,000 and $196,000  as of March
     31, 1998, and March 31, 1997, respectively.

        For properties with  proved or proved  developed oil  and gas  reserves,
     depletion,  depreciation   and  amortization   of  capitalized   costs  was
     calculated  for  fiscal  1998, 1997  and  1996  by  applying the  units-of-
     production method to the estimated amount of such reserves. 

        In fiscal 1998, 1997 and  1996, the Company recognized  non-cash charges
     of approximately $3.1 million, $171,000 and $2.6 million, respectively, due
     to  writedowns of the  carrying value of its  oil and gas properties.   The
     writedowns are the result of the adoption in 1996 of Statement of Financial
     Accounting Standards No. 121 ("SFAS 121") "Accounting for the Impairment of
     Long-Lived  Assets and for Long-Lived Assets to  Be Disposed Of".  SFAS 121
     requires the  Company to assess the  need for an impairment  of capitalized

                                         -24-

<PAGE> 25
     costs of oil and gas properties on a property-by-property basis. This is in
     contrast  to the  Company's  prior policy  of  evaluating the  undiscounted
     future net  revenues of its oil and gas properties  in total.  According to
     SFAS 121, if  an impairment is indicated based  on undiscounted future cash
     flows, then it is to be recognized to the extent that net capitalized costs
     exceed discounted future cash flows.

        The  following table  sets  forth certain  information  relating to  the
     Company's oil and gas operations for the periods indicated:

                                                 Year Ended March 31,

        The Company has not entered into hedging  arrangements and does not have
     any delivery  commitments.  While  hedging arrangements reduce  exposure to
     losses of resulting  from unfavorable  price changes, they  also limit  the
     ability to benefit from favorable market price changes.

     RESULTS OF OPERATIONS

     Comparison of Year Ended March 31, 1998 to Year Ended March 31, 1997

        Contract drilling  revenues in  fiscal 1998  increased by  89% from  the
     previous year.   During fiscal  1998, the Company  experienced very  strong
     demand  for its contract drilling services, which resulted in increased rig
     utilization and higher contract prices.  Rig  utilization was 78% in fiscal
     1998 compared to 52% in the prior fiscal year.

        Contract   drilling  expenses  represented   66%  of  contract  drilling
     revenues in  fiscal  1998 versus  77%  in fiscal  1997.   The  decrease  is
     attributable to the  increase in  the average price  received for  drilling
     contracts.

        Oil  and  gas revenues  decreased  by  15%  during  fiscal 1998.    This
     decrease was a result of weaker oil and gas prices.  Oil and gas production
     expenses remained relatively constant.

        The Company participated  as a working-interest owner in the drilling of
     21 wells during fiscal 1998, of which nine were dry holes.  In fiscal 1997,
     the Company  participated as a working-interest owner in the drilling of 19
     wells, of which seven were dry holes.

        During the  year  ended  March  31,  1998,  the  Company  completed  the
     assembly  of two  additional  drilling  rigs  from  its  inventory  of  rig
     components.    One  of the  rigs  is  capable of  drilling  to  a  depth of
     approximately  8,500 feet,  the  other to  a  depth of  10,000  feet.   The
     addition  of these two U-15 Unit rigs  brings the Company's available fleet
     to  17  rigs.   The increase  in  depreciation, depletion  and amortization
     expense  for fiscal  1998 reflects  the added  equipment(the two  U-15 Unit
     drilling  rigs, drill pipe and miscellaneous drilling equipment) as well as
     the larger number of producing wells in which the Company  has an ownership
     interest (a total of 99 wells in fiscal 1998 versus 92 wells in 1997).

        As noted above, the Company recognized a non-cash charge of $3.1 million
     in fiscal  1998 and $171,000 in fiscal 1997 related to the writedown of the
     carrying value of its oil and gas properties.

        As  described  in  "Item  3.  Legal  Proceedings",  the  Company  was  a
     defendant  in  a lawsuit  filed by  Texas  Property and  Casualty Insurance
     Guaranty  Association  that  had  resulted  in  the  Company's  accrual  of
     approximately $854,000 for a  contingent liability.  On September  9, 1997,
     the  Company  entered  into  a  settlement  agreement   with  the  Guaranty
     Association.  The Company agreed to pay to the Guaranty Association the sum
     of $375,000 in full satisfaction of any liability relating to the Company's
     workers compensation programs  with SFIC and Sir  Lloyd's Insurance Company
     and  the lawsuit brought by  the Guaranty Association.   As a result of the
     settlement, the Company recognized approximately $479,000 as  miscellaneous
     income during the year ended March 31, 1998.

        In addition,  the Company entered  into a settlement  agreement with the
     insurance  agent that  represented  the Company  at  the time  the  workers
     compensation insurance  policies were purchased from Sir  Lloyd's and SFIC.
     The  agent paid the Company  the sum of $180,000 in  full settlement of all
     claims  and liabilities relating to SFIC and Sir Lloyd's Insurance Company.
     This amount was recognized as miscellaneous  income in the year ended March
     31,  1998.     The  Company   also  recorded   approximately  $236,000   of
     miscellaneous income from the sale of junk drill bits.

        Net working  capital was $6.0  million at  March 31,  1998, compared  to
     $2.7  million  at  March  31,  1997.    The  gain  in  working  capital  is
     attributable to an increase in cash and trade receivables.

     Comparison of Year Ended March 31, 1997 to Year Ended March 31, 1996

        Contract drilling revenues  for fiscal 1997 decreased by 13% from fiscal
     1996.  The decrease was  due to a drop-off  in the number of turnkey  wells
     drilled by  the Company  (from 12 wells  in fiscal 1996  to none  in fiscal
     1997).The decline in turnkey contracts, however, was partially offset by an
     increase from the prior year in the average prices the Company received for
     footage and daywork contracts.

        Rig  utilization  rates in  fiscal  1997  and  1996 were  52%  and  45%,
     respectively.    The  fiscal 1997  rate,  and  therefore contract  drilling
     revenues, were adversely affected by extremely low utilization in the first
     three months of the year.   During the first quarter, drilling  prices were
     depressed  and the  Company chose  to underutilize  its  drilling equipment
     rather  than subject  it  to  additional  wear  and  tear  at  unacceptable

                                         -26-

<PAGE> 27
     operating margins.  As a result, the utilization rate for the first quarter
     was only  34%.  In  the second quarter,  however, demand for  the Company's
     contract drilling services began to increase substantially,  resulting in a
     fourth-quarter utilization rate of  70%.  Rig utilization in  the Company's
     operating  market is difficult to  project because of  wide fluctuations in
     drilling  activity.  In addition, the number  of rigs industrywide that are
     actually available for work cannot be accurately determined.

        Contract  drilling expenses  equaled 77%  and  81% of  contract drilling
     revenues   in  fiscal  1997  and  1996,  respectively.    The  decrease  is
     attributable to the  increase in  the average price  received for  drilling
     contracts.

        Oil and gas revenues increased by 48% in  fiscal 1997.  Accordingly, oil
     and gas production expenses increased 67% over the same period.

        Depreciation, depletion and  amortization expense also increased  due to
     the addition of drill pipe and an increase in the number of producing wells
     in which the Company had an ownership interest during fiscal 1997.

        Interest expense increased  100% for fiscal 1997 due to borrowings under
     the  Company's credit facilities with  its bank lender  during this period.
     See "Liquidity and Capital Resources" below.

        Net working capital  was $2.7 million at  March 31, 1997, compared  to a
     negative $1.2  million  at March  31,  1996.   The  improvement in  working
     capital was  due to  an  increase in  accounts  receivable, a  decrease  in
     accounts payable and an increase in cash and cash equivalents.

     Income Taxes

        At March  31,  1998, the  Company  had  approximately $68.3  million  of
     unused net operating loss ("NOL") carryforwards  for tax purposes.  Use  of
     these carryforwards is  dependent upon  the Company's  ability to  generate
     taxable  earnings in  future periods.   These  carryforwards will  begin to
     expire in the  1998 tax  year.  The  Company's ability to  utilize its  NOL
     carryforwards may be substantially limited in the future under the Internal
     Revenue Code of 1986, as amended  (the "Code").  If the Company experiences
     an  ownership  change  under  applicable   provisions  of  the  Code,   the
     carryforward would be limited  to an annual amount determined  by specified
     interest rates  and  other variables.    The Company  does not  believe  an
     ownership change has occurred to date.

        The  effective  tax rates  for  fiscal 1998  and  1997  differ from  the
     statutory  tax rate of 34%  primarily due to the utilization  of NOLs.  Tax
     expense is generally limited to alternative minimum tax.

        The Company  utilizes  an asset  and  liability approach  for  financial
     accounting and reporting for income taxes.  The Company has  a deferred tax
     asset primarily due  to its NOL carryforwards.  The  Company has provided a
     valuation allowance  for the entire balance of deferred tax assets as it is
     likely that a portion of the NOLs may expire  before the Company is able to
     use them.

     Liquidity and Capital Resources   
     
        In January  1996, the  Company entered  into a loan  agreement with  its
     bank  lender  providing  for  a  revolving  credit  facility  (the  "Credit
     Facility")  originally  maturing  on  January  15,  1998.    The  aggregate
     principal  amount of the Company's  borrowings outstanding at  any one time
     under the revolving  facility was limited to the lesser  of $3.0 million or
     one-third of  the borrowing base amount then in effect.  The borrowing base
     amount  was redetermined  by the  bank monthly.   The  Credit Facility  was
     established  to finance the  Company's purchases of drill  pipe and oil and
     gas  exploration activities.  Interest only was payable monthly. The entire
     principal amount  was  due  and payable  on  January 15,  1998,  which  was
     extended  to April  15, 1998.   The  Credit Facility  bore interest  at the
     bank's base  rate and  was secured  by substantially  all of  the Company's
     accounts receivable, drilling  rigs and  related equipment.   At March  31,
     1998, there were no amounts outstanding under the Credit Facility.  

        In August  1996, the Company entered  into a second  loan agreement with
     its bank lender.  This agreement provided for a $2.0 million revolving line
     of  credit (the  "Line  of Credit")  secured by  substantially  all of  the
     Company's producing  oil  and gas  properties.    The Line  of  Credit  was
     established to finance the Company's oil and gas exploration activities and
     for general  corporate purposes.  The  Line of Credit bore  interest at the
     bank's  base rate,  with interest only  to be  paid monthly.   The original
     maturity date of  February 15, 1998,  was extended to April  15, 1998.   At
     that time, the principal amount then outstanding  was due and payable, plus
     any accrued  and unpaid  interest.   At  March 31,  1998,  no amounts  were
     outstanding under the Line of Credit.  

        On May  26, 1998,  the Company  renewed, extended  and consolidated  the
     prior  loan facilities  its bank  lender.   The amended  and restated  loan
     agreement provides for a $5.0  million revolving line of credit secured  by
     the Company's drilling rigs and related equipment, accounts receivable  and
     inventory.   Borrowings under  this line  of  credit bear  interest at  the
     Norwest Bank base rate and  accrued interest is payable monthly.   The loan
     facility matures on May 26, 2000.

        The Company  anticipates  that funds  for  its capital  expenditures  in
     fiscal 1999 will be available from a combination of sources, including  (i)
     borrowings under the line of  credit , (ii) funds raised  through issuances
     of  equity or debt securities in public  or private transactions, and (iii)
     internally generated funds.

        The  Company  presently  anticipates  making  capital   expenditures  of
     approximately $5.5  million in its 1999  fiscal year.  Of  this amount, the
     Company  expects  that approximately  $2.5 million  will  be spent  for the
     acquisition of  drill  pipe,  drill  collars  and  related  equipment,  and
     approximately  $3.0 million  for oil  and gas  exploration  and development
     activities.    It  is  the  Company's  policy,  however,  to  make  capital
     expenditures  based on prevailing  economic conditions, the  results of its
     drilling   activities,   and   other   factors  affecting   its   business.
     Accordingly,  the amounts  actually  spent  in  fiscal  1999  could  differ
     substantially from the amounts estimated.

     Trends and Prices

        Although  the Company  achieved  record  growth, profitability  and  rig
     utilization in  fiscal 1998,  the contract  drilling industry  is currently
     experiencing decreased  demand and  declining prices for  contract drilling
     services  due to the  weakening of  oil and gas  prices.  The  Company will
     certainly be affected by oil and gas industry conditions but cannot predict
     either the  future level  of demand for  its contract drilling  services or
     future conditions in the contract drilling industry.

        In recent  years,  oil and  gas  prices  have been  extremely  volatile.
     Prices  are affected  by market  supply and  demand factors  as well  as by
     actions of state and local  agencies, the U.S. and foreign  governments and
     international cartels.  The Company has no way of accurately predicting the
     supply of and  demand for oil and gas, domestic  or international political
     events or  the effects of  any such factors on  the prices received  by the
     Company for its oil and gas.

     Year 2000 Issues

        The Company has reviewed the effect of the year 2000 issues relating  to
     its information  systems.  The  Company has determined  that the  year 2000
     issues directly related to its information systems will not have a material
     impact  on its business, operations  nor its financial  position.  However,
     the Company  cannot determine  what effect,  if any,  the year 2000  issues
     affecting its vendors, customers and the numerous local, state, federal and
     other U. S. government entities with which it conducts business or which it
     is regulated  or governed or taxed  will have on its  business or financial
     position.

     Recently Issued Accounting Standards

        In June  1997,  the Financial  Accounting Standard  Board (FASB)  issued
     SFAS  No.  130,  "Reporting   Comprehensive  Income",  which  requires  the
     presentation of  comprehensive income in an  entity's financial statements.
     Comprehensive income represents all  changes in equity of an  entity during
     the reporting period,  including net  income and charges  made directly  to
     equity which are excluded from net  income.  The adoption of this statement
     did not have a material impact on the Company's financial disclosures.

        In  June 1997,  the FASB also  issued SFAS  No. 131,  "Disclosures about
     Segments  of  an Enterprise  and  Related  Information", which  establishes
     standards  for the way public  enterprises are to  report information about
     operating  segments  in  annual   financial  statements  and  requires  the
     reporting  of  selected information  about  operating  segments in  interim
     financial  reports issued to shareholders.   SFAS No.  131 also establishes
     standards for  related disclosures about products  and services, geographic
     areas,  and  major customers.    SFAS  No.  131  is effective  for  periods
     beginning after December 15, 1997, at which time the Company will adopt the
     provision.  This statement is not  anticipated to have a material impact on
     the Company's financial disclosures.

                       REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


     To the Board of Directors and Stockholders of TMBR/Sharp Drilling, Inc.:

        We have audited the accompanying balance  sheets of TMBR/Sharp Drilling,
     Inc. (a Texas corporation)  as of March 31, 1998 and  1997, and the related
     statements of operations, stockholders'  equity and cash flows for  each of
     the  three  years in  the period  ended March  31,  1998.   These financial
     statements and the schedule referred to below are the responsibility of the
     Company's management.  Our responsibility is to express an opinion on these
     financial statements and 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 misstatement.   An audit includes examining,  on a test  basis,
     evidence  supporting   the  amounts   and  disclosures  in   the  financial
     statements.   An audit  also includes  assessing the accounting  principles
     used  and significant estimates made  by management, as  well as evaluating
     the overall financial statement  presentation.  We believe that  our audits
     provide a reasonable basis for our opinion.

        In  our opinion,  the  financial statements  referred  to above  present
     fairly,  in  all material  respects, the  financial position  of TMBR/Sharp
     Drilling,  Inc. as  of  March 31,  1998 and  1997, and  the results  of its
     operations and its cash  flows for each  of the three  years in the  period
     ended  March 31,  1998, in  conformity with  generally  accepted accounting
     principles.

        As explained  in Note 1  to the financial  statements, effective January
     1, 1996,  the Company changed  its method of  accounting for impairment  of
     long-lived assets.

        Our audits were made for  the purpose of forming an opinion on the basic
     financial statements taken as a whole.  The schedule listed in the index at
     Item 14(a)2 is presented for purposes of complying with the Securities  and
     Exchange Commission's  rules and  is  not a  part  of the  basic  financial
     statements.   This schedule has  been subjected to  the auditing procedures
     applied  in the  audits  of the  basic financial  statements,  and, in  our
     opinion, fairly states in all material respects the financial data required
     to be set forth therein in relation to the basic financial statements taken
     as a whole.

                            Notes to Financial Statements




     (1)  Organization, Nature of Business and Summary of Significant Accounting
          Policies

     Nature of Operations

          TMBR/Sharp Drilling,  Inc. (the "Company") was  incorporated under the
     laws  of Texas  in October, 1982  under the  name TMBR  Drilling, Inc.   In
     August, 1986, the Company changed its name to TMBR/Sharp Drilling, Inc.

          The Company's  principal businesses are the  domestic onshore contract
     drilling  of oil  and  gas wells  for  major and  independent  oil and  gas
     producers,  and, to a lesser  extent, the exploration  for, development and
     production of  oil and natural gas.   The Company's drilling activities are
     primarily  conducted in  the Permian  Basin of west  Texas and  eastern New
     Mexico.

     Cash and Cash Equivalents

          For  purposes of the statements  of cash flows,  the Company considers
     highly liquid debt  instruments which  have an original  maturity of  three
     months or  less to be cash equivalents.  Cash payments for interest expense
     were approximately $0 in 1998, $278,000 in 1997 and $139,000 in 1996.  Cash
     payments  for taxes due  totaled $29,000, $0 and  $23,000 during 1998, 1997
     and 1996, respectively.

     Marketable Securities

            Under  SFAS No. 115, "Accounting for Certain Investments in Debt and
     Equity  Securities", marketable  securities,  such as  those  owned by  the
     Company,  are classified  as available-for-sale  securities  and are  to be
     reported at market value, with  unrealized gains and losses, net  of income
     taxes,  excluded  from earnings  and reported  as  a separate  component of
     stockholders' equity.   The market value  of these securities at  March 31,
     1998  was not materially different from the historical cost, and therefore,
     no unrealized gains or losses have been recorded.

                            Notes to Financial Statements



     Inventories

          Inventories  consist primarily  of  casing and  tubing.   The  Company
     values  its inventories at the  lower of cost  or estimated net recoverable
     value using the specific identification method.

     Property and Equipment

          Drilling  equipment is  depreciated  on  a units-of-production  method
     based  on the  monthly utilization  of the  equipment.   Drilling equipment
     which  is  not  utilized during  a  month  is depreciated  using  a minimum
     utilization rate  of approximately  twenty-five percent.   Estimated useful
     lives range  from four to  eight years.   Other property  and equipment  is
     depreciated using  the straight-line method of  depreciation with estimated
     useful lives of three to seven years.

          Oil  and gas properties are accounted for using the successful efforts
     method  of accounting.  Accordingly, the costs incurred to acquire property
     (proved  and unproved),  all development  costs and  successful exploratory
     costs are capitalized, whereas the costs  of unsuccessful exploratory wells
     are  expensed.  Geological and geophysical  costs, including seismic costs,
     are charged  to expense when incurred.  In cases where the Company provides
     contract drilling  services related to oil  and gas properties in  which it
     has  an ownership  interest,  the Company's  proportionate  share of  costs
     related  to these  properties is capitalized  as stated  above, net  of the
     Company's  working  interest share  of  profits from  the  related drilling
     contracts.   Capitalized costs  of undeveloped  properties,  which are  not
     depleted until proved reserves  can be associated with the  properties, are
     periodically  reviewed for  possible  impairment.   Such unevaluated  costs
     totaled approximately $111,000 and $196,000 as of March 31,  1998 and 1997,
     respectively.

          Depletion, depreciation  and amortization  of capitalized oil  and gas
     property  costs is provided  using the units-of-production  method based on
     estimated proved or proved  developed oil and gas reserves,  as applicable,
     of the respective property units.

                            Notes to Financial Statements


          Prior to 1996, the Company provided impairments for significant proved
     oil and gas properties  to the extent that  net capitalized costs  exceeded
     aggregated  undiscounted future net cash  flows.  During  1996, the Company
     adopted Statement of Financial  Accounting Standards No. 121  ("SFAS 121"),
     "Accounting  for the  Impairment  of Long-Lived  Assets and  for Long-Lived
     Assets to  Be Disposed Of".   SFAS 121 requires  the Company to  assess the
     need for an impairment of capitalized costs of oil  and gas properties on a
     property-by-property basis.   According to  SFAS 121, if  an impairment  is
     indicated  based on  undiscounted expected  future cash  flows, then  it is
     recognized  to  the extent  that  net capitalized  costs  exceed discounted
     future  cash flows.   In  connection  with the  adoption of  SFAS 121,  the
     Company  provided  an  impairment  of   $2,624,000  in  1996.    Additional
     impairments  of $3,120,000  and $171,000  were recorded  in 1998  and 1997,
     respectively.  Management's estimate of future cash flows is based on their
     estimate of reserves and prices.   It is reasonably possible that  a change
     in reserve  or price estimates could  occur in the near  term and adversely
     impact  management's estimate  of future  cash flows  and consequently  the
     carrying value of properties.

          Major  renewals and  betterments  are capitalized  in the  appropriate
     property  accounts while the cost of  repairs and maintenance is charged to
     operating  expense in the  period incurred.   For assets sold  or otherwise
     retired, the cost and related accumulated depreciation amounts  are removed
     from the accounts and any resulting gain or loss is recognized.

     Drilling Revenues and Costs

          Drilling revenues from footage and daywork contracts are recognized as

     work is performed utilizing the  percentage-of-completion method.  Costs on
     footage and daywork contracts  are recognized in the period incurred.   The
     Company  utilizes  the  completed  contract method  to  recognize  drilling
     revenues  and expenses relating to  turnkey contracts.   Expected losses on
     all  in-process contracts  are  recognized  in  the  period  the  loss  can
     reasonably be determined.

     Risks and Uncertainties

          The preparation  of financial statements in  conformity with generally
     accepted accounting  principles requires  management to make  estimates and
     assumptions  that affect the reported amounts of assets and liabilities and
     disclosure  of contingent  assets  and  liabilities  at  the  date  of  the
     financial  statements and  the reported  amounts of  revenues  and expenses
     during  the reporting  period.   Actual  results  could differ  from  those
     estimates.  Significant estimates with regard to these financial statements
     include the estimate of proved oil and gas reserve volumes  and the related
     present  value of estimated future net revenues therefrom (see Note 8), and
     the valuation allowance for deferred taxes (see Note 4).

                            Notes to Financial Statements



     Net Income (Loss) Per Share of Common Stock

          On   April  1,  1997,  the  Company  adopted  Statement  of  Financial
     Accounting Standards  No.  128  ("SFAS 128")  "Earnings  Per  Share"  which
     superseded Accounting Principles Board Opinion  No. 15 ("APB 15") "Earnings
     Per Share."  SFAS 128 simplifies earnings per share ("EPS") calculations by
     replacing  previously  reported  primary  EPS  with  basic  EPS  which   is
     calculated by  dividing reported earnings available  to common shareholders
     by  the weighted average shares  outstanding.  No  dilution for potentially
     dilutive  securities is included in  basic EPS.   Previously reported fully
     diluted EPS is called  diluted EPS which includes all  potentially dilutive
     securities.

     Stock Based Employee Compensation

          In  October  1995, the  Financial  Accounting  Standards Board  issued
     Statement  of   Financial  Accounting   Standards  No.  123   ("SFAS  123")
     "Accounting for Stock-Based Compensation," which establishes accounting and
     reporting standards for various  stock based compensation plans.   SFAS 123
     encourages the  adoption of  a fair  value based method  of accounting  for
     employee stock options, but permits continued application of the accounting
     method  prescribed by Accounting Principles  Board Opinion No. 25 ("Opinion
     25"), "Accounting for Stock Issued to Employees."   The Company has elected
     to  continue to apply the  provisions of Opinion 25.   Under Opinion 25, if
     the exercise price of  the Company's stock options equals  the market value
     of the  underlying stock on the  date of grant, no  compensation expense is
     recognized.    SFAS  123  requires  disclosure  of  pro  forma  information
     regarding net income and earnings per share as if the Company had accounted
     for  its  employee  stock  options  under  the  fair  value method  of  the
     statement.  See Note 3 "Stockholders' Equity."


     (2)  Debt

          Line of Credit

          On January 16,  1996, the Company entered  into a loan  agreement with
     Norwest  Bank Texas, Midland, N.A. (Norwest) that provided for a $3,000,000
     revolving line of credit secured by the Company's drilling rigs and related
     equipment, accounts receivable and inventory.  Borrowings under the line of
     credit bore  interest at the  Norwest Bank Minnesota,  National Association
     base rate and the  interest was payable monthly.  The loan agreement had an
     extended maturity date of  April 15, 1998, at  which time, the  outstanding
     principal and all of the accrued and unpaid interest were due and payable.

                            Notes to Financial Statements



          In August, 1996, the Company entered into a second loan agreement with
     Norwest.  The  second loan  agreement provided for  a $2,000,000  revolving
     line of credit secured by substantially all of  the Company's producing oil
     and gas properties.   Borrowings under the line of  credit bore interest at
     the Norwest base rate  and the interest was  payable monthly.  The line  of
     credit had an extended maturity date of April 15,  1998, at which time, the
     principal  amount outstanding  was due  and payable,  plus any  accrued and
     unpaid interest.   The borrowings under both  loan agreements were paid  in
     full in February, 1997.

          On  May 26,  1998, the  Company renewed  and  extended the  prior loan
     agreements with Norwest Bank  Texas, N.A..  The  amended and restated  loan
     agreement provides for a $5,000,000 revolving line of credit secured by the
     Company's  drilling rigs  and  related equipment,  accounts receivable  and
     inventory.   Borrowings under the renewed and  extended line of credit bear
     interest at the Norwest Bank base rate and the interest is payable monthly.
     The renewed and extended loan agreement matures on May 26, 2000.

          Leasehold Purchase Obligation

          On  December 9,  1994,  the Company  entered  into an  agreement  with
     Paladin  Exploration Co., Inc. ("Paladin")  to acquire certain  oil and gas
     leases.  The  Company agreed  to reimburse Paladin  an aggregate amount  of
     approximately  $629,000 (including imputed interest  at a rate  of 9.5% per
     annum)  for leasehold  acquisition,  legal and  seismic  costs incurred  by
     Paladin associated with the acquisition of such leases.  At March 31, 1996,
     the obligation outstanding to Paladin had been satisfied.


     (3)  Stockholders' Equity

          (a)  Common Stock

          On  February 13,  1997,  the Company  closed  a private  placement  of
     725,000 shares of  common stock at a  price of $11.00  per share.  The  net
     proceeds from the placement were approximately $7.4 million.

          (b) Stock Option Plans

     1984 Stock Option Plan

          In August of 1984, the Company adopted the 1984 Stock Option Plan (the
     "Plan") which initially  authorized 375,000 shares of  the Company's common
     stock to  be issued as either incentive stock options or nonqualified stock
     options.   This Plan was amended in  August 1986 to increase the authorized
     shares  to 475,000 shares of the Company's common stock.  In January 1988,

                            Notes to Financial Statements


     the Plan was amended to reduce the option price on certain options issued 
     prior to March 31, 1986, to reflect the then current fair market value of 
     the Company's common stock.  The Plan provides that options may be granted 
     to key employees or directors for various terms at a price not less than 
     the fair market value of the shares on the date of the grant.   Options to
     purchase  100,000 shares  of  common stock  are  currently exercisable  and
     outstanding under the Plan.   No additional shares are available  for grant
     as the Plan expired by its own terms in August 1994.  The options that 
     were granted prior to  the expiration of the  Plan, and which  are 
     outstanding, remain subject to the terms of the Plan.

     1994 Stock Option Plan

          In  July 1994,  the Company  adopted its 1994  Stock Option  Plan (the
     "1994  Plan") which  authorized the  grant  of options  to  purchase up  to
     750,000 shares of the Company's common stock.  These options  may be issued
     as either incentive or nonqualified stock options.   The 1994 Plan provides
     that options may be granted to key employees or directors for various terms
     at a price not less than the fair market value of the shares on the date of
     grant.  The 1994 Plan was ratified and approved by the  stockholders at the
     Company's annual meeting of stockholders held on August 30, 1994.

          On  September  3,   1996,  the  Company  granted   465,000  shares  of
     nonqualified stock  options to  key  employees under  the 1994  Plan.   The
     following  sets  forth certain  information  concerning these  nonqualified
     options.

                            Notes to Financial Statements



          In addition to the aforementioned options, during fiscal year 1989, an
     additional 500,000  shares of  nonqualified stock  options were  granted to
     another director who is also an officer.   These options were granted at an
     exercise price of  $0.25 per share (estimated fair market  value at date of
     grant).    On April  4,  1990,  the Board  of  Directors  also approved  an
     additional 500,000 shares  of nonqualified stock options granted to another
     director at  an exercise price  of $0.25  per share (estimated  fair market
     value at date of grant).  

          The  following   sets  forth  certain  information   concerning  these

          All nonqualified options outstanding were earned and exercisable as of
     March 31, 1998.

          Pro forma information regarding  net income and earnings per  share is
     required  by SFAS  123,  and has  been  determined as  if  the Company  had
     accounted  for its employee  stock options under  the fair value  method of
     that  statement.  The fair  value of each option grant  is estimated on the
     date of the  grant using  the Black-Scholes option  pricing model with  the
     following weighted-average assumptions used for  grants in fiscal 1997:  no
     dividend yield, expected volatility of 68.32% and a risk free interest rate
     of 6.7%.

          For purposes of pro forma disclosures, the estimated fair value of the
     options  is amortized  to expense over  the options'  vesting period.   The

          The effects of applying SFAS 123 in this pro forma  disclosure are not
     indicative of future amounts, as SFAS 123 does not apply to awards prior to
     1995 and additional awards are anticipated in future years.
              

     (4)  Income Taxes

          At  March 31, 1998, the  Company had approximately  $68,297,000 of net
     operating loss carryforwards for tax purposes.  Realization of the benefits
     of  these carryforwards is dependent upon the Company's ability to generate
     taxable  earnings  in  future periods.    If  these  carryforwards are  not
     utilized,  they will  begin to  expire  in 1998.  The Company's  ability to
     utilize  its net operating loss  carryforwards may be substantially limited
     in the future under Section 382 of the Internal Revenue Code (IRC).  If the
     Company encounters a change of  control as defined in IRC Section  382, the
     carryforward  would  be limited  to an  annual  amount calculated  based on
     market  value.   The  Company does  not  believe a  change  of control,  as
     defined, has occurred to date.

          The  Company has provided a valuation allowance for the entire balance
     of deferred tax assets at March 31, 1998 and  March 31, 1997, as it is more
     likely than not that the deferred tax asset will not be realized.

          The  effective tax rates for the years  ended March 31, 1998, 1997 and
     1996 differ from the statutory tax rate of 34% primarily due to utilization
     of net operating  loss carryforwards.  Tax expense is  generally limited to
     alternative minimum tax.

                            Notes to Financial Statements


          (a)  General and administrative costs and other income are allocated
               between segments based on identifiable assets.

          (b)  Corporate  income and  expenses  consist of  interest income  and
               expense.

          (c)  Corporate assets are those assets which are not specifically
               identifiable with a segment and consist primarily of cash and
               cash equivalents, short-term investments and prepaid expenses.

          For the  years ended March 31, 1998,  1997 and 1996, contract drilling
     revenues earned from individual customers constituting 10% or more of total
     contract drilling revenues were:

          (a)  two customers in 1998 individually represented approximately 
               14%, and 12% of drilling revenues,

          (b)  four customers in 1997 individually represented approximately
               21%, 18%, 12% and 10% of drilling revenues,

          (c)  three customers in 1996 individually represented approximately
               19%, 18% and 14% of drilling revenues.

          The loss of one  or more of the above customers  could have a material
     adverse effect on the Company, depending  upon the demand for drilling rigs
     at the time of such loss and the Company's ability to find new customers.

     (7)  Contingencies

          In March, 1992, the  Company was notified by  the Texas Department  of
     Insurance  that  the  Company's  former  workers'  compensation   insurance
     carriers,  Sir  Lloyd's  Insurance  Company  and  its  affiliate,  Standard
     Financial Indemnity Corporation ("SFIC"), had been placed in liquidation by
     order of the  201st District Court  of Travis County,  Texas, on March  12,
     1992 in  Cause No. 92-12765, The  State of Texas vs.  Sir Lloyd's Insurance
     Company and  Sir Insurance  Agency, Inc.,  and in  Cause No.  91-12766, The
     State of Texas vs. Standard Financial Indemnity Corporation.  Approximately
     two months before being  ordered into liquidation, SFIC requested  that the
     Company pay policy premiums in the approximate amount of $646,476.  On July
     22,  1993  the  special   deputy  receiver  of  SFIC  billed   the  Company
     approximately  $1,061,000  for  retrospective  premiums, but  adjusted  the
     amount to $854,153 on January 12, 1994.

          In November, 1995,  the Company was  notified that a lawsuit  had been
     filed in Travis County, Texas styled Texas property and Casualty Insurance

                            Notes to Financial Statements


     Guaranty Association  vs. TMBR/Sharp  Drilling, Inc. (Cause  No. 95-12318).
     The Texas  Property and Casualty Insurance  Guaranty Association ("Guaranty
     Association") was seeking a recovery  of past workers' compensation  claims
     advanced  by  the Guaranty  Association  related to  the  Company's workers
     compensation  insurance program  with SFIC.   The Guaranty  Association was
     seeking to recover a total of $803,057.11.

          On  September 9, 1997, the Company entered into a settlement agreement
     with the Guaranty Association.   The Company agreed to pay to  the Guaranty
     Association  the  sum of  $375,000 in  full  satisfaction of  any liability
     relating the Company's workers compensation insurance program with SFIC and
     Sir  Lloyd's  Insurance Company  and the  lawsuit  brought by  the Guaranty
     Association.    The Company  originally  accrued $854,153  relating  to the
     Guaranty  Association's  claim  for reimbursement.    As  a  result of  the
     settlement,  the Company  has eliminated  the accrual  of $854,153  and the
     difference between the accrued amount and  the settlement amount ($479,153)
     has  been recognized  as  miscellaneous income  in the  Company's financial
     statements.

          In  addition, the Company has entered into a settlement agreement with
     the  insurance agent that  represented the Company at  the time the workers
     compensation insurance  policies were purchased from Sir  Lloyd's and SFIC.
     The  agent has paid the  Company the sum of $180,000  in full settlement of
     all  claims  and liabilities  relating to  SFIC  and Sir  Lloyd's Insurance
     Company.   This amount has been  recognized as miscellaneous income  in the
     Company's financial statements.

          The Company  provides for  its workers'  compensation claims prior  to
     September  1997 based upon the  most recent information  available from its
     insurance carrier  concerning  claims and  estimated  costs.   However,  in
     future  years  the  Company   may  receive  retroactive  adjustments,  both
     favorable and unfavorable, related to estimates of claim costs for previous
     years, which  may be material to  the Company's results of  operations.  No
     provision  for retroactive adjustments to claim costs is recorded until the
     Company  receives  notification from  its  insurance  carrier because  this
     amount, if  any, cannot be estimated.  For claims incurred November 1993 to
     September  1997, the Company is generally responsible for the first $10,000
     ($100,000  prior to  November  1993)  in  claim  costs  for  each  workers'
     compensation injury.   Currently the Company is covered  by a fully insured
     workers compensation policy.

          The Company is a defendant in various lawsuits generally incidental to
     its business.  The Company does not believe that the ultimate resolution of
     such litigation will have  a significant effect on the  Company's financial
     position or results of operations.

     (9)  Unaudited supplemental oil and gas reserve information

          The reserve information presented below are only estimates.  There are
     numerous uncertainties inherent in estimating quantities of proved reserves
     and  in projecting  future rates  of production  and timing  of development
     expenditures, including many  factors beyond  the control  of the  Company.
     Reserve  engineering  is a  subjective  process  of estimating  underground
     accumulations of  crude oil and natural  gas that cannot be  measured in an
     exact manner, and the accuracy of any reserve estimate is a function of the
     quality of available data and  of engineering and geological interpretation
     and judgment.  The quantities of oil and gas that are ultimately recovered,
     production and operating costs, the amount and timing of future development
     expenditures  and  future oil  and gas  prices  may all  differ  from those
     assumed in such estimates.

<PAGE> 2
                                     DEFINITIONS





               Section 1.01   Certain  Definitions.     As  used  in   this
          Agreement, terms  defined in the preamble and recitals shall have
          the meanings set forth therein and the following terms shall have
          the following meanings:

                    "Affiliate" as to any Person, shall mean any other
               Person (other  than  a Subsidiary)  which, directly  or
               indirectly, is in "control" of, is controlled by, or is
               under common  control with, such Person.   For purposes
               of  this definition,   control  of  a Person  means the
               power, directly  or indirectly, either to  (i) vote 10%
               or more of the  securities having ordinary voting power
               for the election  of directors of  such Person or  (ii)
               direct  or cause  the direction  of the  management and
               policies  of  such  Person,   whether  by  contract  or
               otherwise.

                    "Agreement"  shall  mean  this  First  Amended and
               Restated  Loan Agreement,  as amended,  supplemented or
               otherwise modified from time to time.

                    "Base  Rate"  shall  mean that  variable  rate  of
               interest per annum established by the Bank from time to
               time as  its "base rate".  Such rate is set by the Bank
               as a  general reference  rate of interest,  taking into
               account such factors as  the Bank may deem appropriate,
               it being understood that  many of the Bank s commercial
               or  other loans  are priced in  relation to  such rate,
               that it  is not  necessarily the  lowest  or best  rate
               actually charged to any customer  and that the Bank may
               make  various commercial  or  other loans  at rates  of
               interest having no relationship to such rate.

                    "Borrowing Base  Amount" shall  mean at any  date,
               the  amount determined pursuant  to Section  2.04 under
               this Agreement at such date.

                    "Borrowing Base Assets"  shall mean the Borrower's
               accounts receivable, drilling  in progress,  inventory,
               equipment,   drill  pipe,  drilling  rigs  and  related
               equipment which  is subject  to the Liens,  privileges,
               priorities and security interests existing and to exist
               under the  terms of  the Security Instruments  from the
               Borrower  or any  other Person  to or  in favor  of the
               Bank.

                    "Borrowing Base Report" shall have the meaning set
               forth in Section 2.04(b).

                           AMOUNT AND TERMS OF COMMITMENTS

               Section 2.01   Revolving Credit Loans.  Subject to the terms
          and  conditions hereof, the Bank  agrees to make revolving credit
          loans (individually, a "Revolving Credit Loan"; collectively, the
          "Revolving Credit  Loans")  to the  Borrower  from time  to  time
          during the Commitment Period in an aggregate principal amount  at
          any  one time  outstanding  not  to  exceed  the  lesser  of  (i)
          $5,000,000.00  or  (ii) one-third  (1/3)  of  the Borrowing  Base
          Amount.  During the  Commitment Period, the Borrower may  use the
          Commitment by borrowing, prepaying  the Revolving Credit Loans in
          whole or in  part, and  reborrowing, all in  accordance with  the
          terms and conditions hereof.

               Section 2.02   Revolving Credit Note.  The  Revolving Credit
          Loans made by the Bank shall be evidenced by a promissory note of
          the  Borrower, substantially  in  the  form  of  Exhibit  A  (the
          "Note").   The Bank shall  maintain in accordance  with its usual
          practice an  account or other record  evidencing the Indebtedness
          of  the Borrower to the Bank resulting from each Revolving Credit
          Loan made by the Bank from time to time, including the amounts of
          principal and interest payable and paid to the Bank from time  to
          time under this Agreement and the Note.  The entries made in such
          account or record of  the Bank shall be  prima facie evidence  of
          the existence  and amounts  of  the obligations  of the  Borrower
          therein recorded; provided, however, that the failure of the Bank
          to maintain any  such account  or record, or  any error  therein,
          shall not in  any manner  affect the  absolute and  unconditional
          obligation of  the Borrower  to repay (with  applicable interest)
          the Revolving  Credit Loans  made to the  Borrower in  accordance
          with the  terms of this Agreement.   The Note shall  (x) be dated
          the Closing  Date, (y) be  stated to  mature two  years from  the
          Closing Date and (z) bear interest on the unpaid principal amount
          thereof from time to time outstanding at the applicable  interest
          rate per  annum as provided  in the Note.   Interest on  the Note
          shall be payable on the dates specified in the Note.

               Section 2.03   Procedure  for  Revolving  Credit  Borrowing.
          The  Borrower   may  borrow  under  the   Commitment  during  the
          Commitment Period on any Business Day, provided that the Borrower

                                       -9-





<PAGE> 10
          shall give the Bank irrevocable notice specifying (A) the  amount
          to be  borrowed and (B)  the requested Borrowing  Date; provided,
          that  such notice shall be waived by the Bank in the case of, and
          only in  the case of, the  initial Revolving Credit Loan  made on
          the  Closing Date.    Each borrowing  pursuant to  the Commitment
          shall be in  an aggregate principal  amount of the lesser  of (i)
          $50,000.00  or  a  whole  multiple  thereof,  or  (ii)  the  then
          remaining unadvanced portion of the available Commitment.

               Section 2.04   Borrowing  Base Amount.   The  Borrowing Base
          Amount shall be determined as follows:

                    (a)  Initial Borrowing Base Amount.  The Borrowing Base
          Amount  shall be  $25,445,743  during the  period  from the  date
          hereof to the  date on which the Borrower receives  notice of the
          first  determination of  the Borrowing  Base Amount  by  the Bank
          pursuant  to Section  2.04(b) and  thereafter the  Borrowing Base
          Amount  shall   be  the  Borrowing  Base   Amount  most  recently
          determined pursuant to Section 2.04(b).

                    (b)  Determinations of the Borrowing Base Amount.   (i)
          No later than 45 days after the end of each fiscal quarter of the
          Borrower throughout the Commitment Period, the Borrower shall, at
          its  own expense,  furnish to  the Bank  a borrowing  base report
          ("Borrowing Base Report"), in the form attached hereto as Exhibit
          B, which  Borrowing Base Report shall  be dated as of  the end of
          each such quarter and shall set forth, by category, the Borrowing
          Base Assets and the Borrowing Base Amount as therein provided.

                         (ii) Within   15  days  after   it  receives  each
          Borrowing Base Report, the Bank shall make a determination of the
          Borrowing Base Amount, and  shall notify the Borrower of  the new
          Borrowing  Base Amount, if any;  provided, that if  the Bank does
          not so notify  the Borrower of a new  Borrowing Base Amount, then
          the  Borrowing Base Amount set forth in the Borrowing Base Report
          furnished  to  the  Bank  by  the  Borrower pursuant  to  Section
          2.04(b)(i)  shall be deemed to be the Borrowing Base Amount until
          a new Borrowing Base Amount is determined by  the Bank and notice
          of such new Borrowing Base Amount is given to the Borrower.  Each
          determination of the Borrowing  Base Amount shall be made  by the
          Bank  in the exercise of  its sole discretion  in accordance with
          the  then current standards and practices of the Bank for similar
          oil  and  gas/contract  drilling  equipment  loans,  taking  into
          account such factors as the Bank may deem appropriate, including,
          without  limitation  the  nature  and extent  of  the  Borrower's
          interest in the Borrowing Base Assets and the anticipated  timing
          and extent of net  operating income therefrom.   The Bank may  in
          its  sole discretion  discount the  value of  any Borrowing  Base
          Asset  set forth in  a Borrowing Base Report  by the same factors
          utilized  by it in discounting the  value of comparable borrowing
          base assets in comparable transactions for comparable borrowers.

                         (iii)     The  Borrower agrees to pay or reimburse
          the  Bank for  all  reasonable out-of-pocket  costs and  expenses
          incurred  by the Bank in  connection with (a)  the examination of
          each Borrowing Base Report furnished to the Bank by the Borrower,
          (b)  any redetermination by the Bank of the Borrowing Base Amount
          pursuant  to such  Borrowing Base  Report  (including independent
          appraisals of the Borrowing  Base Assets which the Bank  may, but
          shall  not  be  required  to,   obtain  in  connection  with  any
          redetermination  of the Borrowing  Base Amount by  the Bank), and
          (c)  the  notification  of  the  Borrower  of  such  redetermined
          Borrowing Base Amount.

                         (iv) Each delivery by the  Borrower to the Bank of
          a  Borrowing  Base  Report  shall  be  deemed  to   constitute  a
          representation  and warranty by the Borrower to the Bank that the
          Borrower  has good  and marketable  title to  the  Borrowing Base
          Assets and  any other property  rights or interests  described in
          such report, and that none of such Borrowing Base Assets or other
          property rights or interests is subject to any Lien other than as
          permitted by Section 5.02.

               Section 2.05   Optional and Mandatory Prepayments.  (a)  The
          Borrower  may  at  any time  and  from time  to  time  prepay the
          Revolving Credit Loans, in  whole or in part, without  premium or
          penalty, upon at  least four Business Days' irrevocable notice to
          the Bank, specifying  the date and amount of prepayment.   If any
          such notice is given,  the amount specified in such  notice shall
          be  due and  payable  on the  date  specified therein.    Partial
          prepayments  shall  be  in   an  aggregate  principal  amount  of
          $50,000.00 or a whole multiple thereof.

                    (b)  If  the aggregate  unpaid principal amount  of the
          Revolving Credit Loans  shall at any time exceed  one-third (1/3)
          of the  Borrowing Base  Amount at such  time, the  Bank shall  so
          notify the Borrower, and the Borrower shall, within 30 days after
          such notification,  prepay the principal of  the Revolving Credit
          Loans  in  an aggregate  amount at  least  equal to  such excess,
          together  with accrued interest on the amount prepaid to the date
          of such prepayment.

               Section 2.06   Payment   Procedure.      All  payments   and
          prepayments made by the Borrower under the Note or this Agreement
          shall be made without  setoff or counterclaim to the Bank  at its
          office at 500 West Texas Avenue, Midland, Texas  79701, and shall
          be made  in  immediately available  funds,  prior to  1:00  p.m.,
          Midland, Texas time, on the date that such payment is required or
          permitted to be  made.   Any payment received  by the Bank  after
          1:00  p.m. on  any  date shall  be  considered for  all  purposes
          (including the  calculation of interest, to  the extent permitted
          by  applicable law)  as having  been made  on the  next following
          Business Day.   If the date  of any payment or  prepayment of the
          Note  falls on a  day which is  not a Business  Day, then for all

          purposes of the Note and this Agreement such date shall be deemed
          to  have  fallen on  the next  following  Business Day,  and such
          extension  of  time  shall  in  such  case  be  included  in  the
          computation of payment of interest.

          
                                      ARTICLE 3

                            REPRESENTATIONS AND WARRANTIES

               To induce the Bank to enter into this  Agreement and to make
          the Revolving  Credit Loans,  the Borrower hereby  represents and
          warrants to  the Bank (which representations  and warranties will
          survive the delivery  of the Note and the making of the Revolving
          Credit Loans hereunder) that:

               Section 3.01   Corporate  Existence;  Compliance  with  Law.
          Borrower  (i) is  duly organized,  validly existing  and in  good
          standing under the laws of the  jurisdiction of its organization,
          (ii)  has the corporate power and authority, and the legal right,
          to own  and operate its property  (including, without limitation,
          the  Borrowing Base Assets), to lease the property it operates as
          lessee  and  to conduct  the business  in  which it  is currently
          engaged,  (iii) is duly qualified as a foreign corporation and in
          good  standing  under the  laws  of each  jurisdiction  where its
          ownership, lease or operation  of property or the conduct  of its
          business requires  such qualification  and (iv) is  in compliance
          with  all Requirements  of  Law except  to  the extent  that  the
          failure  to  comply  therewith   could  not,  in  the  aggregate,
          reasonably be expected to have a Material Adverse Effect.

               Section 3.02   Corporate  Power; Authorization;  Enforceable
          Obligations.  Borrower has the corporate power and authority, and
          the  legal right, to make, deliver and perform the Loan Documents
          to  which it is a party and to borrow hereunder and has taken all
          necessary  corporate action  to authorize  the borrowings  on the
          terms  and conditions  of  this Agreement  and  the Note  and  to
          authorize  the execution,  delivery and  performance of  the Loan
          Documents to  which it is  a party.  No  consent or authorization
          of, filing with, notice to or other act by or in respect of,  any
          Governmental  Authority  or  any  other  Person  is  required  in
          connection with  the borrowings hereunder or  with the execution,
          delivery,  performance, validity  or  enforceability of  the Loan
          Documents to which the Borrower  is a party.  This Agreement  has
          been, and  each other Loan Document  to which it is  a party will
          be,  duly executed and delivered on behalf of the Borrower.  This
          Agreement  constitutes, and each other Loan  Document to which it
          is  a party when executed and delivered will constitute, a legal,
          valid  and binding  obligation  of  Borrower enforceable  against
          Borrower  in accordance with its terms, subject to the effects of
          bankruptcy,  insolvency,  fraudulent conveyance,  reorganization,
          moratorium  and  other  similar  laws relating  to  or  affecting
          creditors'   rights   generally,  general   equitable  principles
          (whether considered in  a proceeding in equity or at  law) and an
          implied covenant of good faith and fair dealing.

<PAGE> 13      
               Section 3.03   No Legal  Bar.  The  execution, delivery  and
          performance  of the  Loan Documents  to which  the Borrower  is a
          party,  the  borrowings hereunder  and  the use  of  the proceeds
          thereof will  not violate any  Requirement of Law  or Contractual
          Obligation  of the Borrower and  will not result  in, or require,
          the creation or imposition  of any Lien (other than  as permitted
          hereby)  on any of Borrower's properties  or revenues pursuant to
          any such Requirement of Law or Contractual Obligation.

               Section 3.04   No Default.  Borrower is not in default under
          or  with respect  to any  of its  Contractual Obligations  in any
          respect which could have a Material Adverse  Effect.  No Event of
          Default has occurred and is continuing.

               Section 3.05   Ownership of Property;  Liens.  Borrower  has
          good record and  marketable title  in fee simple  to, or a  valid
          leasehold interest in, all  its real property and good  title to,
          or  a  valid  leasehold  interest  in,  all  its  other  property
          (including, without  limitation, the Borrowing Base  Assets), and
          none  of such property is subject to any Lien except as permitted
          by Section 5.02.

               Section 3.06   No Burdensome Restrictions.   No  Requirement
          of Law or Contractual Obligation of  Borrower could reasonably be
          expected to have a Material Adverse Effect.

               Section 3.07   Taxes.   Borrower has  filed or caused  to be
          filed  all tax returns which,  to the knowledge  of the Borrower,
          are  required to be filed and has  paid all taxes shown to be due
          and payable on said returns or on any assessments made against it
          or any of its property and all other taxes, fees or other charges
          imposed  on it  or  any  of  its  property  by  any  Governmental
          Authority (other than  any the  amount or validity  of which  are
          currently  being   contested  in   good   faith  by   appropriate
          proceedings and with respect to which reserves in conformity with
          GAAP  have been provided  on the books  of the Borrower);  no tax
          Lien has  been filed, and, to  the knowledge of  the Borrower, no
          claim is being  asserted, with  respect to any  such tax, fee  or
          other charge.

               Section 3.08   Federal Regulations.  No part of the proceeds
          of any Revolving  Credit Loan  will be used  for "purchasing"  or
          "carrying" any  "margin stock" within the  respective meanings of
          each of  the quoted terms under  Regulation G or Regulation  U of
          the Board of Governors  of the Federal Reserve System as  now and
          from time to time hereafter in effect.  If requested by the Bank,
          the  Borrower will  furnish  to  the  Bank  a  statement  to  the
          foregoing effect  in conformity with the requirements  of FR Form
          G-1 or FR Form U-1 referred to in said Regulation G or Regulation
          U, as the case may be.

               Section 3.09   Investment   Company   Act;  Public   Utility
          Holding Company Act; Other  Regulations.  Borrower is not  (a) an
          "investment company", or a company "controlled" by an "investment

          company",  within the  meaning of the  Investment Company  Act of
          1940,  as amended  or (b) a  "holding company" as  defined in, or
          otherwise subject to regulation under, the Public Utility Holding
          Company Act of  1935.  Borrower  has not made  an election to  be
          treated as a utility (as defined in subdivision (2) of subsection
          (a) of Section  35.01 of  the Texas Business  and Commerce  Code.
          Borrower is not primarily engaged in the transmission of goods or
          gas by  pipeline, and does not  hold itself out to  the public as
          having  facilities  for  the  transmission  of  goods or  gas  by
          pipeline which are available for hire by the general public.

               Section 3.10   Purpose  of  Loan.    The   proceeds  of  the
          Revolving  Credit Loans shall be used by the Borrower to purchase
          drill pipe  and related equipment  necessary for the  drilling of
          oil and gas wells, for purchases of undeveloped and developed oil
          and gas properties and for general corporate purposes.

               Section 3.11   Environmental    Matters.       Except    for
          environmental  matters  which,   in  the  aggregate,  could   not
          reasonably be expected to  either (i) result in the  existence of
          an unsatisfied  liability in  excess of a  Material Environmental
          Amount or (ii) have a Material Adverse Effect:

                    (a)  to  the  best  of the  Borrower's  knowledge,  the
               facilities and properties  (real or personal)  owned, leased
               or  operated  by  the  Borrower (the  "Properties")  do  not
               contain, and have not previously contained, any Materials of
               Environmental Concern in amounts or concentrations which (i)

               there is no contamination at, under or  about the Properties
               or violation of  any Environmental Law  with respect to  the

               have any Materials of  Environmental Concern been generated,
               treated, stored  or disposed of at,  on or under  any of the
               Properties in violation of,  or in a manner that  could give
               rise to liability under, any applicable Environmental Law;

                    (e)  no   judicial   proceeding   or  governmental   or

               Borrower is  or will be named as a party with respect to the
               Properties or the  business of Borrower,  nor are there  any
               consent   decrees   or   other  decrees,   consent   orders,
               administrative   orders   or   other   orders,    or   other
               administrative  or  judicial requirements  outstanding under
               any Environmental Law with respect to the Properties  or the
               business of Borrower; and

                    (f)  to the best of the Borrower's knowledge, there has
               been  no  release  or  threat  of  release of  Materials  of
               Environmental Concern at or  from the Properties, or arising
               from  or related  to  the  operations  of  the  Borrower  in
               connection  with the Properties  or otherwise  in connection
               with the business  of the  Borrower, in violation  of or  in
               amounts or in  a manner  that could give  rise to  liability
               under Environmental Laws.

               Section 3.12   Insurance.    The  Borrower   maintains  with
          financially sound  and reputable insurance companies insurance in
          at  least such  amounts  and against  at  least such  risks  (but
          including in any event  public liability) as are usually  insured
          against in the same general area by companies engaged in the same
          or  a  similar  business  and  such  insurance  is  otherwise  in
          compliance with the Loan Documents.

               Section 3.13   Financial  Condition.   The balance  sheet of
          the Borrower as of  December 31, 1997 and the  related statements
          of income and of cash flows for the nine-month period then ended,
          copies of  which have been  delivered to  the Bank, are  true and
          correct in all material respects and present fairly the financial
          condition  of Borrower  as at such  date and  the results  of its
          operations  and  cash flows  for the  periods stated  (subject to
          normal year-end  audit adjustments).   Borrower did not  have, at
          the date of the most recent  balance sheet referred to above, any
          guaranty obligation, contingent liability or liability for taxes,
          or  any   long-term  lease   or  unusual  forward   or  long-term
          commitment,  which is  not reflected  in the  foregoing financial
          statements  or  in the  notes thereto.    During the  period from
          December 31, 1997 to and including the date hereof there has been
          no  sale,  transfer  or  other disposition  by  Borrower  of  any
          material  part of  its business  or property  and no  purchase or
          other  acquisition of  any  business or  property (including  any
          capital  stock of any other  Person) material in  relation to the
          financial  condition of  Borrower at  December 31,  1997.   Since

          December 31,  1997,  no change,  either  in any  case  or in  the
          aggregate, has occurred in the condition, financial or otherwise,
          of Borrower which would have a Material Adverse Effect.  

               Section 3.14   Investments and Guaranties.   At the date  of
          this Agreement,  Borrower has  not made any  material investments
          in, advances to or guaranties of the obligations of any Person.

               Section 3.15   No  Litigation.    There  is  no  litigation,
          legal,  administrative or  arbitral proceeding,  investigation or
          other action  of any nature  pending or, to the  knowledge of the
          Borrower, threatened against or affecting Borrower which involves
          the possibility of any judgment or liability not fully covered by
          insurance,  and which would have a  Material Adverse Effect; and,
          to the  best of  Borrower's knowledge, since  December 31,  1997,
          Borrower has not committed any act, or failed to take any action,
          in connection with the conduct of its business or with respect to
          any Contractual  Obligation  which is  likely  to result  in  the
          assertion  of any adverse claim  of any nature  whatsoever by any
          Person against Borrower or its properties, revenues or assets.

               Section 3.16   Licenses  and  Permits.    Borrower  has  not
          failed  to  obtain  any   license,  permit,  franchise  or  other
          governmental authorization  necessary to the ownership  of any of
          its properties or the conduct of its business, which violation or
          failure would have (in  the event that such violation  or failure
          were  asserted  by  any  Person  through  appropriate  action)  a
          Material Adverse Effect.

               Section 3.17   ERISA.    Each  employee  benefit  plan which
          Borrower has sponsored, maintained or contributed to has complied
          in all  material respects with  the applicable provisions  of the
          Employee  Retirement Income Security Act of 1974, as amended, and
          the Internal Revenue Code of 1986, as amended.

               Section 3.18   No Material Misstatements.   No  information,
          exhibit, schedule or report furnished to the Bank by the Borrower
          in connection  with this Agreement contains  any untrue statement
          of a  material fact or omits to state any material fact necessary
          to make the statements contained therein not misleading.

          asserted  against any Indemnitee  by any  Person (other  than the
          Borrower)  if  the  claim,  demand,  action  or  cause  of action

          any Indemnitee by  any Person  (other than the  Borrower) if  the
          claim, demand, action or cause of action arises out of or relates
          to the Revolving  Credit Loans,  the use or  contemplated use  of

          or  cause of action is  asserted against any  Indemnitee and such
          Indemnitee intends  to  claim indemnification  from the  Borrower

          any, in the  contest of  such claim, demand,  action or cause  of
          action, as hereinafter  provided.   Each Indemnitee  may, and  if
          requested by the Borrower in writing shall, in good faith contest
          the  validity, applicability  and amount  of such  claim, demand,
          action  or  cause   of  action  with  counsel  selected  by  such
          Indemnitee and  reasonably acceptable to the  Borrower, and shall
          permit  the  Borrower  to  participate  in  such  contest.    Any
          Indemnitee  that proposes  to settle or  compromise any  claim or
          proceeding  for which the Borrower  may be liable  for payment of
          indemnity hereunder shall give the Borrower written notice of the
          terms  of such  proposed settlement  or compromise  reasonably in
          advance of settling or compromising such claim or  proceeding and
          shall obtain the Borrower's  prior written consent, which consent
          shall  not  be unreasonably  withheld.   In  connection  with any
          claim,  demand, action or cause of action covered by this Section
          8.03 against more than one Indemnitee, all such Indemnitees shall
          be  represented  by  the  same  legal  counsel  selected  by  the
          Indemnitees and  reasonably acceptable to the Borrower; provided,
          that if such legal  counsel determines in good faith  and advises
          the Borrower  in writing  that representing all  such Indemnitees
          would  or  could result  in a  conflict  of interest  under legal
          requirements  or  ethical  principles applicable  to  such  legal
          counsel  or that  a defense  or counterclaim  is available  to an
          Indemnitee that is not available to all such Indemnitees, then to
          the extent  reasonably  necessary to  avoid  such a  conflict  of
          interest  or to permit unqualified assertion of such a defense or
          counterclaim,  each  Indemnitee  shall be  entitled  to  separate
          representation by  legal counsel selected by  that Indemnitee and
          reasonably  acceptable  to  the  Borrower.    Any  obligation  or
          liability of  the Borrower to  any Indemnitee under  this Section
          8.03  shall  survive  the   expiration  or  termination  of  this
          Agreement and the repayment of the Revolving Credit Loans and the
          payment  of  all other  Indebtedness owing  to  the Bank  for the
          statute  of  limitations  period  applicable  to  such  claim  or
          contest.

               Section 8.04  Invalidity.  In the event that any one or more
          of  the  provisions contained  in this  Agreement, the  Note, any
          Security Instrument  or any other  Loan Document  shall, for  any
          reason, be held invalid, illegal or unenforceable in any respect,
          such invalidity, illegality or  unenforceability shall not affect
          any other provisions of this Agreement, the Note or such Security
          Instrument or other Loan Document.

               Section 8.05   Survival of Agreements.   All representations
          and  warranties  of  the  Borrower  herein  or  in  the  Security
          Instruments, and  all covenants and agreements  herein or therein
          not  fully performed before the  effective date or  dates of this
          Agreement  and of  the Security  Instruments, shall  survive such
          date or dates.

               Section 8.06   Successors  and Assigns.   All  covenants and
          agreements  contained by  or on  behalf of  the Borrower  in this
          Agreement, the Note  and the Security Instruments  and other Loan
          Documents shall bind its  successors and assigns and  shall inure
          to  the benefit  of  the Bank  and  its successors  and  assigns.
          Borrower  shall not, however, have the right to assign its rights
          hereunder  or  any interest  herein,  without  the prior  written
          consent  of  the  Bank.    In  the  event  that  the  Bank  sells
          participations in or assigns the Note or other Indebtedness owing
          to the Bank to other lenders (which the Bank may  undertake to do
          in  its sole discretion), each  of such other  lenders shall have
          the rights to setoff against such Indebtedness and similar rights
          or Liens to the same extent as may be available to the Bank.

               Section 8.07   Renewal,  Extension  or  Rearrangement.   All
          provisions of this  Agreement and of  any Security Instrument  or
          other Loan  Document relating to  the Note or  other Indebtedness
          owing to the Bank shall apply with equal force and effect to each
          and all  promissory notes hereinafter executed which  in whole or
          in part represent a  renewal, extension for any period,  increase
          or  rearrangement  of any  part  of  the Indebtedness  originally
          represented   by  the  Note  or   of  any  part   of  such  other
          Indebtedness.

               Section 8.08   Waivers.  No course of dealing on the part of
          the Bank, its officers, employees, consultants or agents, nor any
          failure  or  delay by  the Bank  with  respect to  exercising any
          right, power or privilege  of the Bank under this  Agreement, the
          Note or  any Security  Instrument or  other  Loan Document  shall
          operate  as a  waiver thereof,  except as  otherwise provided  in
          Section 8.02 hereof.

               Section 8.09   Cumulative  Rights.   Rights and  remedies of
          the  Bank  under  this  Agreement,  the  Note  and  the  Security
          Instruments and the other Loan Documents shall be cumulative, and
          the  exercise or  partial exercise  of any  such right  or remedy
          shall not preclude the exercise of any other right or remedy.

               Section 8.10   Construction.   THIS  AGREEMENT IS,  AND  THE
          NOTE WILL  BE, A CONTRACT  MADE UNDER AND  SHALL BE CONSTRUED  IN
          ACCORDANCE WITH AND  GOVERNED BY THE LAWS OF THE UNITED STATES OF
          AMERICA AND  THE STATE OF TEXAS,  AS SUCH LAWS ARE  NOW IN EFFECT
          AND, WITH RESPECT TO  USURY LAWS, IF ANY, APPLICABLE TO  THE BANK
          AND TO THE EXTENT ALLOWED THEREBY, AS SUCH LAWS  MAY HEREAFTER BE
          IN EFFECT WHICH ALLOW A HIGHER MAXIMUM  NONUSURIOUS INTEREST RATE
          THAN SUCH LAWS NOW ALLOW.

               Section 8.11   Taxes,  Etc.    Any  taxes  (excluding income
          taxes) payable or ruled payable by  any Governmental Authority in
          respect  of this Agreement, the Note,  any Security Instrument or
          any other Loan Document  shall be paid by the  Borrower, together
          with interest and penalties, if any.

               Section 8.12   Governmental Regulation.  Anything  contained
          herein to  the contrary notwithstanding,  the Bank  shall not  be
          obligated  to extend  credit  to the  Borrower  in an  amount  in
          violation  of  any  limitation  or prohibition  provided  by  any
          applicable statute or regulation.

               Section 8.13   Counterparts.  This Agreement may be executed
          in  one or more counterparts, and it  shall not be necessary that
          the  signatures of  all parties  hereto be  contained on  any one
          counterpart  hereof.    Each   counterpart  shall  be  deemed  an
          original, but all counterparts  together shall constitute one and
          the same instrument.

               Section 8.14   Conflicts.    If  there  is ever  a  conflict
          between  the terms,  conditions, representations,  warranties and
          covenants contained in this  Agreement and the terms, conditions,
          representations, warranties or covenants in any of the other Loan
          Documents  executed  by  the  Borrower, the  provisions  of  this
          Agreement  shall control;  provided, however,  the fact  that any
          term, condition,  representation, warranty or  covenant contained
          in such other Loan Document is not contained herein shall not be,
          or be deemed to be, a conflict.

               Section 8.15   Exhibits.      The   exhibits,  annexes   and
          schedules attached to this  Agreement are incorporated herein and
          shall be considered  a part  of this Agreement  for the  purposes
          stated herein, except that  in the event of any  conflict between
          any of the provisions of such exhibits, annexes and schedules and
          the  provisions  of  this   Agreement,  the  provisions  of  this
          Agreement shall prevail.

               Section 8.16   Acknowledgment  by Borrower.   As  a material
          inducement  to the Bank to execute and deliver this Agreement and
          to  make   the  Revolving  Credit  Loans,   the  Borrower  hereby
          acknowledges, agrees  and represents that (i) the Prior Notes are
          renewed, extended and consolidated,  but not extinguished, by the
          Note; (ii) the Liens,  security interests and assignments created
          and   evidenced   by   the  Prior   Security   Instruments   are,
          respectively, valid and subsisting Liens, security interests  and
          assignments of the respective dignity and priority recited in the
          Prior Security Instruments; (iii) there  are no claims or offsets
          against, or defenses or counterclaims to, the terms or provisions
          of  the Prior  Security  Instruments, and  the other  obligations
          created  or evidenced  by  the Prior  Security Instruments;  (iv)
          Borrower  has  no  claims,  offsets,  defenses  or  counterclaims
          arising from any  of the Bank s acts or omissions with respect to
          any  collateral, the  Prior  Security Instruments  or the  Bank s
          performance  under the  Prior Security  Instruments; and  (v) the
          Bank is not in default and no event has occurred  which, with the
          passage  of time, giving of  notice, or both,  would constitute a
          default  by the  Bank  of its  obligations  under the  terms  and
          provisions of the Prior Security Instruments.

                       REVOLVING LINE OF CREDIT PROMISSORY NOTE


          $5,000,000.00                                        May 26, 1998


               FOR VALUE RECEIVED, in  the manner, on the dates and  in the
          amounts  herein stipulated,  TMBR/SHARP DRILLING,  INC.,  a Texas
          corporation (the "Borrower"),  promises and agrees to  pay to the
          order of Norwest Bank Texas, N.A., a national banking association
          (the "Bank"),  in Midland,  Midland County, Texas,  the principal
          sum  of Five  Million and  No/100 Dollars ($5,000,000.00)  or, if
          less, the aggregate unpaid balance  of all advances hereunder, in
          lawful  money of  the United  States of  America, which  shall be
          legal  tender  in  payment of  all  debts  and  dues, public  and
          private, at the time of payment, and to pay interest thereon from
          the date  of advance  until maturity  at a  rate per  annum which
          shall from day to day be equal to the lesser of (a) the Base Rate
          in effect from day to day (calculated on the basis of actual days
          elapsed, but computed as  if each calendar year consisted  of 360
          days) or (b) the Highest Lawful Rate.  Each change in the rate of
          interest charged  under this Revolving Line  of Credit Promissory
          Note (this "Note")  shall, subject  to the  terms hereof,  become
          effective,  without notice  to the  Borrower, upon  the effective
          date of  each change in the Base Rate or the Highest Lawful Rate,
          as the  case may be.   Notwithstanding the  foregoing, if at  any
          time the Base Rate exceeds the  Highest Lawful Rate, the rate  of
          interest  on this  Note shall  be limited  to the  Highest Lawful
          Rate,  but any subsequent reductions  in the Base  Rate shall not
          reduce  the rate of interest hereon below the Highest Lawful Rate
          until the  total amount of interest  accrued hereon approximately
          equals  the amount of interest which would have accrued hereon if
          the Base Rate had at all times been in effect.  In the event that
          at maturity (stated or  by acceleration), or at final  payment of
          this Note, the total amount of interest paid or accrued hereon is
          less than the amount of interest which would have accrued  if the
          Base Rate had at all times been in effect, then, at such time and
          to the extent permitted by applicable laws, Borrower shall pay to
          the Bank an amount equal to the difference between (a) the lesser
          of the amount  of interest which would  have accrued if the  Base
          Rate had  at all times been  in effect or the  amount of interest
          which would have accrued  if the Highest  Lawful Rate had at  all
          times been in  effect, and  (b) the amount  of interest  actually
          paid or  accrued on this Note.  All of the past due principal and
          accrued interest hereunder shall, at the option of the Bank, bear
          interest from maturity (stated or by acceleration)  until paid at
          a  rate per  annum equal to  the Highest  Lawful Rate.   Interest
          calculations  may   be  made  ten  days  prior  to  any  interest
          installment due date under this Note, in which event, if there is
          an adjustment in the  interest rate in accordance with  the terms
          hereof  during  such  ten-day  period, then  the  Borrower  shall
          subsequently, on demand, pay to the Bank any underpayment, or the


                                       -36-


<PAGE> 37
          Bank shall  pay to the Borrower, any overpayment, as the case may
          be, as a result of any adjustment during such ten-day period.

               This  Note (a) is the Revolving Line of Credit Note referred
          to in the First Amended and Restated Loan Agreement, dated  as of
          the  date hereof  (as the  same may  be amended,  supplemented or
          otherwise  modified from  time  to time,  the "Loan  Agreement"),
          between the  Borrower and the Bank,  (b) is subject to  the terms
          and  conditions  thereof, and  (c)  is  subject  to optional  and
          mandatory prepayments in whole or in part as provided in the Loan
          Agreement.  Reference is made to the Loan Agreement for a further
          statement of the rights,  remedies, powers, privileges, benefits,
          duties and obligations  of the  Borrower and the  Bank under  the
          Loan Agreement  and this  Note.   Capitalized  terms used  herein
          which are defined in  the Loan Agreement shall have  such defined
          meanings unless otherwise defined herein.

               This   Note   represents   the   renewal,   extension,   and
          consolidation, but not the extinguishment, of the Prior Notes.

               This Note is secured  as provided in the Loan  Agreement and
          in  the other Loan Documents,  to which reference  is hereby made
          for a  description of the properties  and assets in  which a Lien
          and  security interest has been granted, the nature and extent of
          the security, the terms  and conditions upon which the  Liens and
          security interests were granted  and the rights of the  holder of
          this Note with respect thereto.

               Each  borrowing under  this  Note shall  be  in the  minimum
          amount of $50,000.00 (or the unadvanced portion hereof, whichever
          is less) and shall be made only in accordance with the provisions
          of the  Loan Agreement.  Subject  to the terms hereof  and of the
          Loan Agreement,  Borrower may borrow,  repay and reborrow  at any
          time and from time to time under this Note.

               Interest on  the outstanding principal balance  of this Note
          shall  be due and  payable monthly on  the fifteenth  day of each
          month, commencing  June 15, 1998. The  then outstanding principal
          balance of this Note and all accrued and unpaid interest shall be
          due and payable on May 26, 2000.

               Time is of the essence of this Note.  Upon the occurrence of
          any one  or more of the  Events of Default specified  in the Loan
          Agreement,  all amounts then remaining unpaid  on this Note shall
          become,  or may be declared  to be, immediately  due and payable,
          all as provided therein.  

               It  is the intention  of the Borrower and  the Bank that the
          Bank  shall  conform strictly  to  usury laws  applicable  to it.
          Accordingly,   if  the  transactions  contemplated  by  the  Loan
          Agreement and this  Note would be usurious  as to the  Bank under
          laws applicable to it (including the laws of the United States of
          America  and the State of  Texas or any  other jurisdiction whose
          laws may  be mandatorily  applicable to the  Bank notwithstanding
          the  other provisions of the Loan Agreement and this Note), then,

                                       -37-


<PAGE> 38
          in that  event, notwithstanding anything to the  contrary in this
          Note,  the Loan  Agreement or  any other  Loan Document  or other
          agreement entered into in connection with or as security for this
          Note, (i) the aggregate of all  consideration which is contracted
          for,  taken, reserved, charged or received by the Bank under this
          Note,  the Loan Agreement or any other Loan Document or agreement
          entered  into in  connection with  or as  security for  this Note
          shall under no circumstances exceed the maximum amount allowed by
          such applicable law, and any excess shall be credited by the Bank
          on the principal amount  of the Indebtedness to the Bank  (or, to
          the extent  that the principal  amount of the  Indebtedness shall
          have been  or would thereby be paid in full, refunded by the Bank
          to the Borrower); and (ii) in the event that the maturity of this
          Note is accelerated by  reason of an Event  of Default under  the
          Loan Agreement or otherwise,  or in the event of  any prepayment,
          then  such  consideration  that  constitutes  interest  under law
