                            NOTES TO FINANCIAL STATEMENTS



          The amounts presented in the  balance sheet as of March 31,  1995 were
     derived from the  Company's audited  financial statements  included in  its
     Form  10-K Report  filed  for the  year  then  ended.   The  notes to  such
     statements are incorporated herein by reference.
      

     (1) Management's Representation

          In  the opinion  of management,  the accompanying  unaudited financial
     statements contain all adjustments (all of which are  of a normal recurring
     nature)  necessary to present fairly the Company's financial position as of
     December 31,  1995 and March  31, 1995, the  results of operations  for the
     three and nine months ended  December 31, 1995 and 1994, and the cash flows
     for the nine month period ended December 31, 1995 and 1994.

          While the Company believes that the disclosures presented are adequate
     to  make the  information  not  misleading,  it  is  suggested  that  these
     condensed financial  statements be read  in conjunction with  the financial
     statements and the related notes in the Company's Annual Report on Form 10-
     K for the fiscal year ended March 31, 1995.


     (2) Summary of Significant Accounting Policies

     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.

          Oil  and gas properties are accounted for using the successful efforts
     method.   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
     also  has an ownership interest, the Company's proportionate share of costs
     related to  these properties  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


                                         -11-

<PAGE> 12

     proved reserves  can be  associated with  the properties, are  periodically
     reviewed for possible impairment. 

          Depletion  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.  Other property and equipment is depreciated using the straight-line
     method of depreciation with estimated useful lives of three to seven years.

          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.

     Net Income (Loss) Per Common Share

          Net income (loss) per share  of common stock is based on  the weighted
     average number of common shares outstanding during each period.  All common
     stock equivalents are considered  anti-dilutive for purposes of calculating
     the  net loss per  share and dilutive  for purposes of  calculating the net
     income per share.
      

     (3)  Debt

          Line of Credit

          The  Company and its lender  entered into an  agreement which provides
     for a $1,000,000 revolving line of  credit ("LOC") secured by the Company's
     accounts  receivable.   At  December 31,  1995,  the Company  had  borrowed
     $500,000 against the LOC.  The LOC  bears interest at 1% above the  Norwest
     Bank Minnesota,  Base Rate and matures on July 15, 1996.  In January, 1996,
     the Company and its bank lender entered into a loan agreement providing for
     the renewal,  extension and increase in  principal amount of the  LOC.  See
     Note 7.

          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.  During the quarter
     ended  December 31, 1995, the Company satisfied this obligation to Paladin.
     See Item 2, Management's Discussion and Analysis of Financial Condition and
     Results of Operations - Liquidity and Capital Resources.


     (4)  Stockholders' Equity
      
          1984 Stock Option Plan



                                         -12-

<PAGE> 13

          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,
     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 108,000 shares of common stock are currently outstanding under the
     Plan, with  60,500 of the options  being exercisable at  December 31, 1995.
     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.   The
     Company has not granted any options under the 1994 Plan.


     (5)  Employee Benefits

          Effective  May  1,  1995,   the  Company  established  the  TMBR/Sharp
     Drilling,  Inc. Employee Retirement Plan  which is a  401(K) profit sharing
     plan.   Company contributions are discretionary and have been currently set
     at  25% for  each dollar  contributed by  each eligible  employee, limited,
     however, to a maximum of 5% of the employee's compensation.

     (6)  Contingencies

          On March 19, 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 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.  Although the Company disputes  the amount claimed by
     SFIC and its receiver, the Company is presently unable to determine whether


                                         -13-

<PAGE> 14

     and to what extent such amount is, in fact, an accurate estimate of amounts
     owed to SFIC,  if any, largely as  a result of the difficulty  of verifying
     the  insurance   carrier's  estimated   claims  and  adjustments   and  the
     unavailability  of SFIC personnel.   However,  an accrual  was made  in the
     Company's financial statements for the amount in question.

          In  a  related  development, on  November  3,  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") seeks 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 is seeking to recover a total of $803,057.11.

          The Company disagrees with the claims made by the Guaranty Association
     and intends to vigorously  defend this lawsuit.  The  Company believes that
     if  the Guaranty Association's claim  is ultimately determined  to be valid
     and  enforceable, then the Receiver's  claim against the  Company is either
     without merit or that its  claim would be offset against the claims  of the
     Guaranty  Association.  For these reasons,  the Company has not accrued the
     Guaranty Association's claim in its financial statements.

     (7)  Subsequent Events

          On  January 16, 1996,  the Company entered into  a loan agreement with
     Norwest  Bank Texas, Midland, N.A. (Norwest) that provides 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  bear interest at  the Norwest Bank  Minnesota, National Association
     base rate  and the interest is  payable monthly.  The  loans mature January
     15,  1998 at  which time  the  then outstanding  principal and  all of  the
     accrued and unpaid interest is  due and payable.  At February 1,  1996, the
     Company had borrowed $500,000 under the facility.


     Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
              RESULTS OF OPERATIONS

     Liquidity and Capital Resources

          Pursuant to its agreement with  an exploration and production company,
     the  Company  agreed  to  fund approximately  $629,000  (including  imputed
     interest at a rate of 9.5%  per annum) for leasehold acquisition, legal and
     seismic costs incurred in acquiring certain oil and gas leases.  During the
     quarter ended  December 31,  1995, the remaining  obligation (approximately
     $37,000) relating to this agreement was satisfied.  See Note (3).

          The Company  intends to  meet  its capital  resource requirements  for
     fiscal  1996 through available cash balances on hand and cash flow provided
     through  operations.  If needed,  the Company will  also consider borrowing
     funds from its bank lender.  See Note (7).

          The  Company believes it owns a  sufficient number of drilling rigs to


                                         -14-

<PAGE> 15



     remain competitive within  its areas of operation.   However, the cash flow
     generated  from operations  will continue  to be  directly affected  by the
     level  of  drilling activity  in the  Company's  areas of  operations.   By
     focusing  on drilling contracts which  can provide operating  cash flow and
     maintaining  its  cost  containment   program,  the  Company  believes  its
     operating  cash flow will improve.   Cash provided  by operating activities
     was $3,001,000 for the  nine months ended December 31,  1995, compared with
     an outflow of $67,000 for the nine months ended December 31, 1994.

     Results of Operations

          Total revenues  were approximately $5,371,000 and  $17,290,000 for the
     three  and  nine  months  ended  December  31,  1995,  respectively,  which
     represents a 10% decrease and a 30% increase over the same periods in 1994,
     respectively.   Operating expenses as a  percent of revenues were  102% and
     94%  for the three  and nine months ended  December 31, 1995, respectively,
     versus 92% and 96%  for the same periods of the prior  year.  The operating
     results were negatively affected by a decrease in rig utilization rates.

          Rig utilization rates  were 42% and 45% for the  three and nine months
     ended December 31, 1995, respectively,  as compared to 52% and 42%  for the
     same periods in 1994.  Rig utilization in the Company's operating market is
     difficult to project, primarily  due to the intense competition  within the
     industry  and  the inability  to accurately  determine  the number  of rigs
     available for work.

          Oil  and gas revenues  increased by approximately 21%  and 80% for the
     three  and nine months ended  December 31, 1995,  respectively, compared to
     the same  periods in 1994.   Accordingly, oil  and gas production  expenses
     also  increased.  Depreciation and depletion expense has also increased due
     to  the increase in the number of producing  wells in which the Company has
     acquired ownership interests.

          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  grants the Company the right to explore for oil and natural
     gas offshore.   The license  covers approximately 1.1  million gross  acres
     within the waters of Palau.   The Company is considering the feasibility of
     conducting exploration activities jointly with other parties, entering into
     farmout  arrangements  with third  parties or  entering into  other "earned
     interest"  arrangements   with  industry  partners.     Under  the  license
     agreement, the Company is  required to commence drilling of  an exploratory
     well no later than 9-5-97, and an  additional well within six months of the
     initial  well.   The  Company estimates  that  it will  cost  approximately
     $6,000,000 to drill the two wells.

          Net working capital  was a  negative $1,598,000 for  the period  ended
     December 31,  1995 as compared to  $716,000 for the period  ended March 31,
     1995.  This decrease in working  capital is a result of a decrease  in cash
     and  an increase in accounts  payable.  The  Company expended approximately
     $4.7  million in cash  during the nine  months ended December  31, 1995 for
     asset  acquisitions, including  a 110  National drilling  rig with  a depth
     capacity of 22,000 feet.  Additionally, the Company continues to invest  in
     oil and gas exploration projects.
                                         
                                         -15-
<PAGE> 16     
     Financial Condition

          Recently, the  Company has  entered into "turnkey"  drilling contracts
     which create substantially more  economic risk to the Company  than footage
     or daywork contracts.   Under a turnkey contract, the  Company contracts to
     drill a well to a specified depth and bears the risk of loss to that depth.
     Typically,  turnkey contracts are  more profitable than  footage or daywork
     contracts but  the Company could experience substantial  losses if drilling
     problems occur under its turnkey contracts.

          For  the  nine  months  ended  December  31,  1995,  the  Company  has
     experienced improved operating results which can be attributable to several
     factors.  The Company's oil and gas exploration program has been successful
     and drilling rig utilization rates have stabilized as have drilling prices.
     The Company has  substantially improved its  safety record which has  had a
     positive  impact  on worker's  compensation costs.    All of  these factors
     coupled with a successful cost containment program have positively impacted
     the Company's operating margins.  However,  the Company is still subject to
     considerable  uncertainty due  to the  instability of  oil and  gas prices,
     decreased demand for contract drilling services and the intense competition
     prevalent in the contract drilling industry.

     PART TWO - OTHER INFORMATION

     Item 1.  Legal Proceedings

          On March 19, 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 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.  Although the Company disputes  the amount claimed by
     SFIC and its receiver, the Company is presently unable to determine whether
     and to what extent such amount is, in fact, an accurate estimate of amounts
     owed to SFIC, if  any, largely as a  result of the difficulty  of verifying
     the  insurance   carrier's  estimated   claims  and  adjustments   and  the
     unavailability of  SFIC personnel.   However, an  accrual was  made in  the
     Company's financial statements for the amount in question.

          In  a  related  development, on  November  3,  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") seeks 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 is seeking to recover a total of $803,057.11.

          The Company disagrees with the claims made by the Guaranty Association
     and intends to vigorously defend  this lawsuit.  The Company  believes that
     if  the Guaranty Association's claim  is ultimately determined  to be valid
     and  enforceable, then the Receiver's  claim against the  Company is either
     without merit or that  its claim would be offset against  the claims of the
     Guaranty Association.   For these reasons, the  Company has not accrued the
     Guaranty Association's claim in its financial statements.

          (the  "Borrower"),  and  NORWEST  BANK TEXAS,  MIDLAND,  N.A.,  a
          national banking association (the "Bank").


                                       RECITALS

          (the  "Prior   Note")  in   the  original  principal   amount  of
          $1,000,000.00;

               WHEREAS, the outstanding principal balance of the Prior Note
          on the date hereof is $500,000.00;

               WHEREAS,  the Borrower  has requested  that the  Bank renew,
          extend and increase the principal amount of the Prior Note;

               WHEREAS, the  Bank is  agreeable to the  Borrower's requests
          but  only upon and subject to the  terms and provisions which are
          hereinafter specified.

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

                                      ARTICLE 1

                                     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.



<PAGE> 2

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

               Minnesota, National  Association ("Norwest Minnesota"),
               from time to time as its "base rate."  Such rate is set
               by  Norwest Minnesota  as a  general reference  rate of
               interest, taking  into account such factors  as Norwest
               Minnesota  may deem  appropriate,  it being  understood
               that many of  Norwest Minnesota'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 Norwest Minnesota 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(a)(i)
               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   and   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).

                    "Borrowing  Date"  shall  mean  any  Business  Day
               specified  in a notice  pursuant to  Section 2.03  as a
               date on which  the Borrower requests  the Bank to  make
               Revolving Credit Loans hereunder.

                    "Business  Day"  shall mean  a  day  other than  a
               Saturday, Sunday  or legal holiday for commercial banks
               under the laws of the State of Texas.

                    "Cash Flow" shall mean, with respect to any period
               of calculation thereof, the sum  of (i) the net  income
               (or loss) from continuing operations of Borrower during
               such   period   (excluding  extraordinary   income  but
               including    extraordinary    expenses),   plus    (ii)
               depreciation, deple-tion and  amortization expenses  of
               Borrower during such period.

               represent  a minority  of the  total number  of persons
               comprising  the  entire  Board;   or  (ii)  a   Person,
               including a  "group" as defined in  Section 13(d)(3) of

          during the Commitment  Period in an aggregate principal amount at

<PAGE> 9

          any  one time  outstanding  not  to  exceed  the  lesser  of  (i)
          $3,000,000.00  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
          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 to be made
          on  the Closing Date.   Each borrowing pursuant  to the Revolving
          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.  (i) The  Borrowing
          Base Amount  shall be $10,163,400.00  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).

<PAGE> 10
                    (b)  Determinations of the Borrowing Base Amount.   (i)
          No later than 45 days after  the end of each month 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 report
          shall  be dated as of  the end of  each such month  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
          redetermi-nation  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.  (i)  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.

                    (ii)  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 prepay-
          ments 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.

                            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

                                          11


<PAGE> 12


          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.

               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 (including, without
          limitation, the Borrowing Base  Assets), and good title to,  or a
          valid  leasehold interest in, all its other property, and none of
          such  property  is subject  to any  Lien  except as  permitted by
          Section 5.02.

               Section 3.06   No  Burdensome  Restrictions.     Except   as
          described in  Schedule 3.06, 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 pipe-
          line 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, and for general corporate purposes.

               Section 3.11   Environmental Matters.   Except for  environ-
          mental matters which,  in the aggregate, could not  reasonably be
          expected  to either (i) result in the existence of an unsatisfied

                                          13

          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)
               constitute or constituted a violation of, or (ii) could give
               rise to liability under, any Environmental Law;

                    (b)   to  the  best of  the  Borrower's knowledge,  the
               Properties  and  all operations  at  the  Properties are  in
               compliance,  and  have  in  the  last  five  years  been  in
               compliance,  with  all  applicable  Environmental  Laws, and
               there is no  contamination at, under or about the Properties
               or violation  of any Environmental  Law with respect  to the
               Properties or the business operated by Borrower;

                    (c)  Borrower has not received any notice of violation,
               alleged  violation,  non-compliance, liability  or potential
               liability regarding environmental matters or compliance with
               Environmental  Laws with regard to any  of the Properties or
               the business  of the  Borrower, nor does  the Borrower  have
               knowledge  or reason to believe that any such notice will be
               received or is being threatened;

                    (d)  to the best of the Borrower's knowledge, materials
               of  Environmental  Concern  have  not  been  transported  or
               disposed of from  the Properties  in violation of,  or in  a
               manner or to a  location which could reasonably  be expected
               to give rise to liability under, any Environmental  Law, nor
               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
               administrative action is pending or, to the knowledge of the
               Borrower, threatened, under  any Environmental Law to  which
               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,
               administra-tive   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

                                          14





<PAGE> 15
               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; provided, however,  Borrower
          does not maintain insurance on its drilling rigs.

               Section 3.13   Financial  Condition.   The balance  sheet of
          the  Borrower as of September 30, 1995 and the related statements
          of income and of cash flows for the six-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
          September 30, 1995  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 September 30,  1995.   Since
          September  30, 1995,  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.    Except  as  set  forth  in
          Schedule 3.06,  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 September  30, 1995, 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


                                          15




<PAGE> 16
          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.

                                AFFIRMATIVE COVENANTS

               The Borrower  hereby agrees that, so long  as the Commitment
          remains  in effect  or  any Indebtedness  is  owing to  the  Bank
          hereunder  or  under the  Note or  any  other Loan  Document, the
          Borrower shall:

               Section 4.01   Financial Statements and Reports.  Furnish or
          cause  to be  furnished to the  Bank from  time to  time (i) such
          information regarding  the  business and  affairs  and  financial
          condition of the Borrower as the Bank may reasonably request, and
          (ii) without request, the following:

                    (a)  Annual Financial Statements -  promptly after
               becoming  available, but  in any  event within  90 days
               after  March 31 of  each  year, a  copy of  the audited

               Documents  shall be satisfactory  in form and substance
               to  the Bank,  and  the Bank  shall have  received such
               other documents  and legal  opinions in respect  of any

          Agreement,  the Note, the Security Instruments  or the other Loan
          Documents  may be  amended  or  waived  if,  but  only  if,  such
          amendment or waiver is  in writing and is  signed by each  Person

               Section 8.03   Indemnity by  Borrower.  The  Borrower agrees
          to indemnify, save and hold harmless the Bank and its Affiliates,
          directors,    officers,    agents,   attorneys    and   employees

                                          30


<PAGE> 31


          asserted  against any  Indemnitee by any  Person (other  than the
          Borrower)  if the  claim,  demand,  action  or  cause  of  action
          directly  or indirectly  relates to  a claim,  demand, action  or
          cause  of action that such  Person asserts or  may assert against
          the  Borrower, any  Affiliate  of the  Borrower  or any  officer,
          director  or shareholder of the Borrower; (b) any and all claims,
          demands, actions or  causes of action  that are asserted  against
          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
          proceeds of the Revolving Credit Loans or the relationship of the
          Borrower   and   the  Bank   under   this   Agreement;  (c)   any
          administrative  or investigative  proceeding by  any Governmental
          Authority arising out of or related to a claim, demand, action or
          cause of  action described in clauses  (a) or (b) above;  and (d)
          any  and all  liabilities, losses,  costs or  expenses (including
          reasonable attorneys' fees and disbursements) that any Indemnitee
          suffers  or incurs as a result of any of the foregoing; provided,
          that no  Indemnitee shall be entitled to  indemnification for any
          liability,  loss,  cost  or  expense  caused  by  its  own  gross
          negligence or willful  misconduct.  If any  claim, demand, action
          or  cause of action is  asserted against any  Indemnitee and such
          Indemnitee  intends to  claim  indemnification from  the Borrower
          under this  Section 8.03,  such Indemnitee shall  promptly notify
          the  Borrower, but the failure to so promptly notify the Borrower
          shall  not affect  the  obligations of  the  Borrower under  this
          Section  8.03  unless  such  failure  materially  prejudices  the
          Borrower's  right to  participate, or  the Borrower's  rights, if
          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

                                          31

          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 pro-
          visions 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.

          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.

          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
          counter-part  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,
          representa-tions,  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.

                       REVOLVING LINE OF CREDIT PROMISSORY NOTE


          $3,000,000.00                                    January 16, 1996


               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,  Midland, N.A., a  national banking
          association (the "Bank"), in  Midland, Midland County, Texas, the
          principal sum of Three Million and No/100 Dollars ($3,000,000.00)
          or, if less, the  aggregate unpaid balance of all  advances here-
          under, 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

                                        35

          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 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 and extension, and increase
          in  principal  amounts,  but   not  the  extinguishment,  of  the
          principal amount outstanding on the Prior Note.

               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  interest 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  February  15,  1996.  The  then  outstanding
          principal  balance  of  this  Note  and all  accrued  and  unpaid
          interest shall be due and payable on January 15, 1998.

               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

                                          36

<PAGE> 37
          laws may  be mandatorily  applicable to the  Bank notwithstanding
          the  other provisions of the Loan Agreement and this Note), then,
          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
          applicable  to the Bank may  never include more  than the maximum
          amount allowed  by such applicable  law, and excess  interest, if
          any, provided for in  this Note, the Loan Agreement  or otherwise
          shall be  cancelled automatically by  the Bank as of  the date of
          such acceleration  of prepayment and, if  theretofore paid, shall
          be   credited  by  the  Bank  on  the  principal  amount  of  the
          Indebtedness (or, to the extent that the principal amount of such
          Indebtedness  shall have been or  would thereby be  paid in full,
          refunded by the Bank to the Borrower).

               To the  extent that Article  5069-1.04 of the  Texas Revised
          Civil  Statutes  is  relevant to  the  Bank  for  the purpose  of
          determining the Highest Lawful  Rate, the applicable rate ceiling
          under such Article shall be determined by the  indicated (weekly)
          rate  ceiling from time to time  in effect, subject to the Bank's
          right  subsequently  to change  such  method  in accordance  with
          applicable law.

               All  parties now  or hereafter liable  with respect  to this
          Note, whether  maker, principal,  surety, guarantor,  endorser or
          otherwise,  hereby  waive presentment,  demand,  protest and  all
          other notices of any kind.

               THIS  NOTE  IS PERFORMABLE  AND  PAYABLE  IN  THE COUNTY  OF
          MIDLAND, STATE  OF TEXAS,  AND SHALL  BE CONSTRUED IN  ACCORDANCE
          WITH, AND GOVERNED BY, THE LAWS OF THE STATE  OF TEXAS; PROVIDED,
          HOWEVER, THAT THE LAWS PERTAINING TO ALLOWABLE  RATES OF INTEREST
          MAY, FROM TIME  TO TIME, BE  GOVERNED BY THE  LAWS OF THE  UNITED
          STATES OF AMERICA.
