Borrowers,  YALE E. KEY, INC. ("Yale"), KEY ENERGY  DRILLING, 
INC.  D/B/A CLINT HURT  DRILLING  ("Hurt"),  and WELLTECH

corporations  or other entities,  identified as the Borrowers in
Section  10.6(c) and their  successors and assigns.  All
references to "Borrower" shall mean each of them individually,
and all references to "Borrowers"  shall mean each of them, 
jointly,  severally and collectively, and the successors and
assigns of each.

         1.2  The  "Lender"  is The  CIT  Group/Credit  Finance,
 Inc.  and  its successors and assigns.

         1.3 (i) Yale (the  "Original  Borrower"),  Eskey,  Inc.
(the  "Original Guarantor"),  and Fidelcor Business Credit
Corporation ("Fidelcor") entered into a loan transaction (the
"Original Loan  Transaction") on December 29, 1988, and, in
connection  therewith,  Yale executed a Promissory  Note in
favor of Fidelcor (the "Original Note"),  and Yale delivered to
Fidelcor a Security Agreement (the "Security  Agreement") and
certain related agreements and documents.  As part of the
Original  Loan  Transaction,  Eskey,  Inc.  executed a Corporate
 Continuing Guaranty  (the   "Original   Guaranty")  in  favor 
of  Fidelcor,   guaranteeing unconditionally  Yale's obligations
to Fidelcor. The Original Note, the Security Agreement, the
Original Guaranty, and all documents related thereto are
referred to herein as the "1988 Agreements".

                  (ii) On June 29,  1990,  Yale  and  Fidelcor 
entered  into an Amended and Restated  Loan and Security 
Agreement  (the  Security  Agreement as amended by the Amended
and Restated Loan and Security Agreement,  being referred to
herein as the "Original Loan Agreement"); Yale executed a
Restated Promissory Note which amended and restated the Original
 Note; and Eskey,  Inc.  reaffirmed its obligations  under the
Original  Guaranty by executing the Reaffirmation and Amendment
of Guaranty and  Subordination  Agreement;  all of the foregoing
being referred  to as the  "Amendment  Agreements".  On July 25,
 1990,  Skeeter  Well Service,  Inc.  ("Skeeter")  executed a
Guaranty  in favor of Lender and entered into a Security
Agreement with Lender (the "Skeeter Agreements").  The Amendment
Agreements  and the Skeeter  Agreements,  along with all 
documents  executed in connection therewith, are referred to as
the "1990 Agreements".

                  (iii) On February 4, 1991,  Fidelcor  sold and
assigned to CIT the Original Loan Transaction,  including all of
its right,  title, and interest in and to the 1988 Agreements
and the 1990 Agreements.

by WellTech, Inc. and payable to CIT (the "Original             
      WellTech Note").

                  (xi) The Merger was  concluded  and became

                  (xii) Yale, Hurt and WellTech have  requested,
 and Lender has agreed,  to  consolidate  and amend the Second

SECTION 2. LOANS AND OTHER CREDIT ACCOMMODATIONS

         2.1 Revolving Loans. Lender shall,  subject to the
terms and conditions contained  herein,  make  revolving  loans
to each of the Borrowers  ("Revolving Loans") in amounts 
requested  by such  Borrower  from time to time,  but not in
excess of such Borrower's Net  Availability  existing 
immediately  prior to the making of the requested loan and
provided the requested loan would not cause the outstanding 
Obligations of all Borrowers in the aggregate to exceed the
Maximum Credit;  provided further,  however, that Lender shall
be under no obligation to make  Revolving  Loans to any Borrower
 following  the filing of an  involuntary petition,  action or 
proceeding  against any Borrower or guarantor  (and for so long
thereafter as such  involuntary  petition,  action,  or
proceeding  remains undismissed  or  unstayed,  and subject to
the terms and  provisions  of Section 7.1(h)) seeking 
reorganization,  arrangement or readjustment of such Borrower's
or guarantor's  debts or for any other relief under the 
bankruptcy  laws of the United States now or hereafter in effect.

         (a) The " Maximum Credit" is set forth in Section
10.1(a) hereof.

         (b) "Accounts  Availability" equals the product
obtained by multiplying the  outstanding  amounts of a
Borrower's  separate  Eligible  Accounts,  net of taxes, 
discounts,  allowances,  and credits  given or claimed,  by the
Eligible Accounts  Percentage set forth in Section 10.1(b),  and
deducting  therefrom any Reserves.

         (c) The "Net Availability" shall be calculated at any
time as an amount equal to the Maximum Credit minus the
aggregate  amount of all  then-outstanding Obligations by the
Borrowers to Lender.

         (d) "Yale's Net Availability" shall be calculated as
the lesser of

              (i) the Maximum Credit, less the Obligations; and

              (ii) Yale's Accounts Availability, less Yale's
Revolving Loans.

         (e) "Hurt's Net Availability" shall be calculated as
the lesser of:

              (i) the Maximum Credit, less the Obligations; and

                                        4





               (ii) $2,000,000, less the sum of Hurt's Term
Loan, Hurt's                     Capital Expenditures Loan, and
Hurt's Revolving Loans; and

               (iii)  Hurt's Accounts Availability, less Hurt's
Revolving Loans.

         (f) "WellTech's Net Availability" shall be calculated
as the lesser of:

              (i) the Maximum Credit, less the Obligations; and

              (ii) WellTech's Accounts  Availability,  less
WellTech's Revolving                   Loans and Accommodations.

         (g)  "Eligible  Accounts"  are  accounts  created by a
Borrower  in the ordinary  course of its business  which are and
remain  acceptable to Lender for lending purposes. General
criteria for Eligible Accounts are set forth below but may be
revised from time to time, by Lender,  in its sole  judgment, 
on fifteen (15) days prior written notice to the Borrowers. 
Lender shall, in general, deem accounts  to be Eligible 
Accounts  if: (1) such  accounts  arise from bona fide completed
 transactions and have not remained unpaid for more than the
number of days after the invoice date set forth in Section
10.1(c); (2) the amounts of the accounts  reported to Lender are
absolutely owing to a Borrower and do not arise from sales on
consignment, guaranteed sale or other terms under which payment
by the account debtors may be conditional or contingent;  (3)
the account  debtor's chief  executive  office or principal
place of business is located in the United States;  (4) such
accounts do not arise from progress  billings or retainages or
bill  and  hold  sales;  (5)  there  are  no  contra  
relationships,   setoffs, counterclaims or disputes existing
with respect thereto (but that portion of the account for which
no contras, setoffs,  counterclaims or disputes are applicable
may be deemed an  Eligible  Account)  and there are no other 
facts  existing or threatened which would impair or delay the 
collectibility of all or any portion thereof;  (6) the goods 
giving  rise  thereto  were not at the time of the sale subject
to any liens except those permitted in this Agreement; (7) such
accounts are not  accounts  with  respect to which the  account 
debtor or any officer or employee  thereof is an officer, 
employee or agent of or is affiliated with any Borrower, 
directly  or  indirectly,  whether  by virtue  of family 
membership, ownership,  control, management or otherwise; (8)
such accounts are not accounts with  respect to which the
account  debtor is the United  States or any State or political 
subdivision  thereof or any department,  agency or
instrumentality of the United  States,  any State or political 
subdivision,  unless there has been compliance  with the
Assignment of Claims Act or any similar State or local law, if 
applicable;   (9)  the  Borrowers  have  delivered  to  Lender 
or  Lender's representative  such original documents as Lender
may have reasonably  requested pursuant to Section 5.8 hereof in
connection with such accounts and Lender shall have received a
verification of such account,  reasonably satisfactory to it, if
sent to the  account  debtor or any other  obligor  or any 
bailee  pursuant  to Section 5.4 hereof;  (10) there are no
facts  existing or  threatened  which are reasonably  likely to 
result in any  adverse  change  in the  account  debtor's
financial  condition;  (11) such accounts owed by a single
account debtor or its affiliates  do not  represent  more than
twenty  percent  (20%) of all otherwise Eligible Accounts of all
Borrowers,  provided, however, that with respect to the Eligible
 Accounts of Parker & Parsley,  Inc.,  such  accounts may not
represent more than  thirty-two  percent (32%) of all otherwise 
Eligible  Accounts of all Borrowers  (accounts  excluded from
Eligible  Accounts  solely by reason of this subsection (11)
shall nevertheless be considered Eligible Accounts to the extent
of the amount of such accounts  which does not exceed twenty
percent (20%) or in the case of Parker & Parsley, Inc.
thirty-two percent (32%), of all otherwise

                                        5





Eligible Accounts);  (12) such accounts are not owed by an
account debtor who is or whose  affiliates  are "past due" (i.e.
 where more than 90 days have elapsed since the invoice date of
such  accounts)  upon other accounts owed to Borrowers
comprising  more than fifty percent (50%) of the accounts of
such account debtor or its affiliates owed to such Borrower; 
(13) such accounts are owed by account debtors whose total
indebtedness to a Borrower does not exceed the amount of any
customer credit limits as established,  and changed, from time
to time by Lender upon notice to such Borrower (accounts
excluded from Eligible Accounts solely by reason  of this 
subsection  (13)  shall  nevertheless  be  considered  Eligible
Accounts to the extent the amount of such accounts does not
exceed such customer credit  limit);  (14) with respect to which
the account debtor is located in the states of New Jersey,
Minnesota, West Virginia, or any other state requiring the
filing of a Business  Activity Report or similar document in
order to bring suit or otherwise  enforce its remedies  against
such account debtor in the courts or through any judicial 
process of such state,  unless such Borrower has qualified to do
business  in such  states,  or has filed a Notice of  Business 
Activities Report or  similar  document  with such  states,  as 
appropriate,  for the then current  year;  and (15)  such 
accounts  are  owed by  account  debtors  deemed creditworthy at
all times by Lender.

         (h)  Lender  shall  have a  continuing  right  to 
deduct  reserves  in determining   Accounts   Availability   and
 each   individual   Borrower's  Net Availability ("Reserves"), 
and to increase and decrease such Reserves from time to time, if
and to the extent that, in Lender's  sole  judgement,  such
Reserves are necessary to protect Lender against any state of
facts which does, or would, with notice or passage of time or
both, constitute an Event of Default or have a material adverse
effect on any Collateral.  Lender may, at its option, implement
Reserves by  designating  as  ineligible a sufficient  amount of
accounts  which would  otherwise be Eligible  Accounts so as to
reduce Net  Availability  and/or each individual  Borrower's
Accounts  Availability by the amount of the intended Reserve.

         (i)  Subject  to the terms and  conditions  hereof, 
including  but not limited  to  the  existence  of  sufficient  
Net   Availability   and  Accounts Availability, each Borrower
agrees to borrow amounts from time to time such that the
aggregate outstanding Revolving Loans and Term Loans to both
Borrowers shall at all times equal or exceed the principal 
amount set forth in Section  10.1(d) as the Minimum Borrowing. 
Each Borrower  covenants,  represents and warrants to Lender
that they will jointly and  severally  maintain Net 
Availability  at all times in amounts  sufficient  to permit 
Borrowers  to comply  with the  Minimum Borrowing  requirement. 
In the event Borrowers do not borrow sufficient amounts to 
continuously  meet or exceed the Minimum  Borrowing 
requirement,  or in the event  Borrowers  fail to  maintain  Net
 Availability  at all times at  amounts sufficient to permit
Borrowers to comply with the Minimum Borrowing requirement,
then, in either of such events,  Borrowers shall be deemed to
have borrowed from Lender  jointly  such  additional  sums from
time to time as may be necessary in order for Borrowers to
continuously meet the Minimum Borrowing requirement. Such sums
shall be added to the principal  amount of the outstanding 
Revolving Loans for  the  sole  purpose  of  computing  
interest  due  under  this   Agreement. Notwithstanding  the
provisions of the immediately  preceding  sentence,  Lender
shall have no obligation to disburse to  Borrowers,  or any of
them,  any amount deemed to have been  borrowed  for  purposes
of meeting  the  Minimum  Borrowing requirement  unless
Borrowers  actually  requested such disbursement from Lender and
unless the Net Availability is sufficient to support such
disbursement.

                                        6





         2.2 Term Loan.

         (a) The amount of any term loans made by Lender to any 
Borrower on the date hereof is set forth in Section  10.2(a)
(the "Initial  Term  Loans").  Such Initial Term Loans are
evidenced by Promissory  Notes delivered by each Borrower
receiving  an Initial  Term Loan to Lender and shall be  repaid,
 together  with interest  and  other  amounts,  in  accordance 
with  this  Agreement  and  such Promissory Notes.

         (b) The amount of any  additional  term loans which may
be available to any  Borrower  at  Lender's  discretion  after 
the date  hereof is set forth in Section 10.2(b) ("Capital
Expenditures Loans" and together with the Initial Term Loans,
the "Term Loans").  Such Capital Expenditures Loans shall be
evidenced by promissory  notes  delivered by such  Borrower to
Lender,  in form and substance reasonably  acceptable to Lender,
and shall be repaid together with interest and other amounts in
accordance with this Agreement and such promissory notes.

         (c) All appraisals conducted in connection with the
Term Loans shall be conducted  at  Borrowers'  expense  by  an 
independent   appraiser   reasonably acceptable  to Lender.  In
addition,  with  respect to the Capital  Expenditures Loans, 
(i) Lender shall have received such  appraisal at least thirty
(30) days prior to the date of the requested advance for such
Capital  Expenditures  Loan, (ii) Lender shall have received
from Borrower evidence  reasonably  satisfactory to Lender that
the machinery  and  equipment has been  purchased by Borrower
and delivered to such Borrower at one of its locations set forth
in Section  10.6(e) and that such  machinery  and  equipment is
in place and  operational  and (iii) Lender shall have received 
invoices and such other  documentation as reasonably requested
by Lender.

         2.3 Accommodations.

         (a) Lender  may, in its sole  discretion,  issue or
cause to be issued, from time to time at any Borrower's  request
and on terms and conditions and for purposes satisfactory to
Lender, credit accommodations  consisting of letters of credit, 
 bankers'   acceptances,   merchandise  purchase  guaranties  or
 other guaranties or indemnities for such Borrower's account 
("Accommodations").  Each such Borrower shall execute and
perform  additional  agreements  relating to the Accommodations 
in form and  substance  reasonably  acceptable to Lender and the
issuer of any  Accommodations,  all of which  shall  supplement 
the  rights and remedies granted herein.  Any payments made by
Lender or any affiliate of Lender in connection with the 
Accommodations  shall  constitute  additional  Revolving Loans
to such Borrower.

         (b) In addition to the fees and costs of any issuer in
connection  with issuing  or   administering   Accommodations,  
the  Borrower   requesting   the Accommodation  shall pay
monthly to Lender,  on the first day of each  month,  a charge
on such Borrower's open Accommodations at the rate per annum set
forth in Section 10.3(a) (the "Accommodation Charges").

         (c) No  Accommodation  will be issued (i) unless the
full amount of the Accommodation  requested,  plus  fees and 
costs for  issuance  (unless  paid by Borrower),  is less than
the Net Availability  existing immediately prior to the issuance
of the requested Accommodation,  or (ii) if the requested
Accommodation would cause the outstanding  Obligations to exceed
the Maximum Credit,  or (iii) if the requested Accommodation
would cause the open amount of Accommodations

                                        7





issued to all Borrowers to exceed, at any time, the 
Accommodation  sublimit set forth  in  Section  10.3(b),  or 
(iv)  if the  expiry  date  of  the  requested Accommodation 
extends  beyond  the  initial  term  (or  any  renewal  terms 
if applicable) of this Agreement.

         (d)  All   indebtedness,   liabilities  and 
obligations  of  any  sort whatsoever,  however  arising, 
whether present or future,  fixed or contingent, secured  or 
unsecured,  due or to become  due,  paid or  incurred,  arising 
or incurred  in  connection  with any  Accommodation  shall be
included in the term "Obligations," as defined herein, and shall
include, without limitation, (i) all amounts  due or which may
become due under any  Accommodation;  (ii) all amounts charged
or chargeable to any Borrower or to Lender by any bank,  other
financial institution or correspondent bank which opens, 
issues, or is involved with such Accommodations;  (iii) Lender's
 Accommodation  Charges and all fees,  costs and other charges
of any issuer of any Accommodation;  and (iv) all duties,
freight, taxes,  costs,  insurance  and all such other  charges 
and  expenses  which may pertain  directly or indirectly to any
Obligations or  Accommodations  or to the goods or documents
relating thereto.

         (e) Each Borrower  unconditionally  agrees to indemnify
and hold Lender harmless  from  any and all  loss,  claim  or 
liability  (including  reasonable attorneys'  fees) arising from
any  transactions or occurrences  relating to any Accommodation 
established or opened for such Borrower's account, the
Collateral relating  thereto and any drafts or acceptances 
thereunder,  including any such loss or claim due to any action 
taken by an issuer of any  Accommodation.  Each Borrower 
further agrees to indemnify and hold Lender harmless for any
errors or omissions  other than gross  negligence,  bad faith, 
or willful  misconduct  in connection with the  Accommodations, 
whether caused by Lender, by the issuer of any  Accommodation 
or otherwise.  Each Borrower's  unconditional  obligation to
indemnify and hold Lender harmless under this provision shall
not be modified or diminished for any reason or in any manner
whatsoever, except for Lender's gross negligence,  bad faith, 
or willful  misconduct.  Each Borrower  agrees that any charges
made to Lender by any issuer of any Accommodation shall be
conclusive on such Borrower and may be charged to such
Borrower's account.

         (f) Lender shall not be responsible for (i) the
conformity of any goods to the documents  presented;  (ii) the
validity or genuineness of any documents; or (iii) delay, 
default, or fraud by any Borrower or shipper and/or anyone else
in connection with the Accommodations or any underlying
transaction.

         (g) Each Borrower  agrees that any action taken by
Lender,  if taken in good faith, or any action taken by an
issuer of any  Accommodation,  under or in connection with any 
Accommodation,  shall be binding on such Borrower and shall not
create any resulting  liability to Lender.  In furtherance 
thereof,  Lender shall have the full right and  authority  to
clear and resolve any  questions of non-compliance  of 
documents;  to give any  instructions  as to  acceptance  or
rejection of any documents or goods; to execute for each
Borrower's  account any and all applications for steamship or
airway guarantees, indemnities or delivery orders; to grant any
extensions of the maturity of, time of payment for, or time of
presentation of, any drafts,  acceptances,  or documents; and to
agree to any amendments, renewals, extensions, modifications,
changes or cancellations of any of the terms or conditions of
any of the applications or Accommodations.  All of the foregoing
actions may be taken in Lender's sole name, and the issuer
thereof shall be  entitled  to  comply  with and  honor  any and
all such  documents  or instruments executed by or received
solely from Lender, all without any notice

                                        8





to or any consent from any Borrower.  None of the foregoing
actions described in this  subsection  (g) may be  taken by any 
Borrower  without  Lender's  express written consent.

         2.4 Certain Amounts Due on Demand.  Lender may, in its
sole discretion, make or permit Revolving Loans, 
Accommodations,  or other Obligations in excess of the Maximum
Credit,  Accounts  Availability or Net Availability or
applicable formulas  or  sublimits.  All or any  portion of such
 excess(es)  shall  become immediately due and payable upon
Lender's demand.

SECTION 3. INTEREST AND FEES

         3.1 (a)  Interest  on the  Revolving  Loans  shall  be 
payable  by the Borrowers  on the first day of each month, 
calculated  upon the  closing  daily balances  in  the  loan 
account  of the  Borrowers  for  each  day  during  the
immediately preceding month, at the per annum rate (the "Annual
Rate") set forth as the  Interest  Rate in Section  10.4(a). 
The Annual  Rate shall  increase or decrease by an amount equal
to each increase or decrease,  respectively,  in the Prime Rate
(as herein defined), effective as of the date of each such
change, On and after any Event of Default or termination or
non-renewal hereof, interest on all unpaid matured  obligations
shall accrue at a rate equal to two percent (2%) per annum in
excess of the Annual Rate otherwise  payable until such time as
all Obligations are indefeasibly paid in full (notwithstanding
entry of any judgment against any  Borrower  or the  exercise of
any other right or remedy by Lender), and all such interest
shall be payable on demand.  Notwithstanding the foregoing
provisions of this Section 3.1(a) regarding the rates of
interest  applicable to Revolving Loans and any rate of interest
applicable to any Term Loan:

                  (i) If at any time the  amount  of  interest 
computed  on the         basis of either the Annual Rate or the
rate provided by any  Promissory         Note pursuant to
Section 2.2 of this  Agreement (the "Note Rate") would        
exceed the amount of  interest  computed  upon the basis of the
maximum         rate of interest  (the  "Maximum  Legal Rate") 
permitted by applicable         state or  federal  law in 
effect  from time to time  hereafter,  after         taking into
account,  to the extent required by applicable law, any and     
   all fees,  payments,  charges  and  calculations  provided 
for in this         Agreement or in any other agreement between
Borrowers or any individual         Borrower and Lender, the
interest payable under this Agreement shall be         computed
on the basis of the Maximum  Legal  Rate,  but any  subsequent  
      reduction in the Annual Rate or the Note Rate (if
applicable) shall not         reduce such  interest  thereafter 
payable  hereunder  below the amount         computed  on the
basis of the  Maximum  Legal Rate until the  aggregate        
amount equals the total amount of interest  which would have
accrued if         such interest had been at all times computed
solely on the basis of the         Annual Rate and the Note Rate
(if applicable).

                  (ii) No  agreements,  conditions,  provisions
or  stipulations         contained  in this  Agreement  or any 
other  instrument,  document  or         agreement between
Borrowers, or any of them, and the Lender, or default         of
any  Borrower,  or  the  exercise  by the  Lender  of the  right
 to         accelerate the maturity of the payment of the
principal and interest or         to exercise any option 
whatsoever  contained in this  Agreement or any         other
agreement among Borrowers, or any of them, and the Lender, or
the         arising of any  contingency  whatsoever,  shall 
entitle  the Lender to         collect, in any event, interest
exceeding the Maximum Legal Rate and in         no event shall
any Borrower be obligated to pay interest exceeding such        
Maximum Legal Rate and all agreements,  conditions or
stipulations,  if         any, which may in any event or
contingency  whatsoever operate to bind,         obligate or
compel any Borrower to pay a rate of interest

                                        9





         exceeding  the Maximum  Legal Rate,  shall be without 
binding force or         effect,  at law or in  equity,  to the 
extent  only of the  excess  of         interest  over such
Maximum  Legal Rate. In the event that any interest         is 
charged  in excess  of the  Maximum  Legal  Rate  ("Excess"), 
each         Borrower  acknowledges and stipulates that any such
charge shall be the         result of an accidental and bona
fide error,  and such Excess shall be,         first,  applied
to reduce the  principal  amount of  indebtedness  then        
unpaid  hereunder;  second,  applied to reduce  such  Borrower's
 other         Obligations  hereunder;  and third, returned to
such Borrower, it being         the  intention  of the  parties 
hereto not to enter at any time into a         usurious or
otherwise illegal  relationship.  Each Borrower  recognizes     
   that,  with  fluctuations  in the Annual Rate,  the Note
Rate,  and the         Maximum Legal Rate, such an 
unintentional  result could  inadvertently         occur. By the
execution of this Agreement, each Borrower covenants that       
 (x) the credit or return of any Excess shall  constitute the
acceptance         by each  Borrower of such  Excess,  and (y)
no  Borrower  shall seek or         pursue any other remedy, 
legal or equitable,  against Lender, based in         whole or
in part upon the  charging  or  receiving  of any  interest in  
      excess of the maximum  authorized by applicable law. For
the purpose of         determining whether or not any Excess has
been contracted for, charged,         or received by Lender, all
interest at any time contracted for, charged         or received
by the Lender in connection  with this  Agreement  shall be     
   amortized,  prorated,  allocated  and spread in equal parts 
during the         entire term of this Agreement.

                  (iii) The provisions of Section  3.1(a)(ii)
shall be deemed to         be incorporated  into every document
or  communication  relating to the         Obligations which
sets forth or prescribes any account,  right or claim         or
alleged  account,  right or claim of the Lender with respect to
each         Borrower (or any other obligor in respect of the
Obligations),  whether         or not any  provision  of Section
3.1 is referred to therein.  All such         documents and 
communications  and all figures set forth therein shall,        
for the sole purpose of  computing  the extent of the 
liabilities  and         obligations  of each  Borrower (or any
other  obligor)  asserted by the         Lender  thereunder,  be
 automatically  recomputed  by such Borrower or         obligor,
 and by any court  considering the same, to give effect to the  
      adjustments or credits required by Section 3.1(a)(ii).

                  (iv) If the applicable  state or federal law
is amended in the         future to allow a greater  rate of 
interest  to be charged  under this         Agreement  or any
other loan  documents  than is  presently  allowed by        
applicable  state or  federal  law,  then the  limitation  of 
interest         hereunder shall be increased to the maximum
rate of interest allowed by         applicable  state or federal
law as amended,  which  increase  shall be         effective 
hereunder on the effective date of such  amendment,  and all    
    interest charges owing to the Lender by reason thereof shall
be payable         upon demand.

         (b) The  "Prime  Rate"  is the per  annum  rate  of 
interest  publicly announced by Chase Manhattan Bank, New York,
New York, or the applicable rate of its  successors or assigns, 
from time to time as its prime rate (the prime rate is not 
intended to be the lowest rate of  interest  charged by Chase 
Manhattan Bank, New York, New York, or its successors or
assigns, to its borrowers).

         3.2 The  Borrowers  collectively  shall pay Lender on
the date hereof a Closing Commitment Fee in the amount set forth
in Section 10.4(b),  which fee is fully earned as of the date
hereof.

                                       10





         3.3 The Borrowers  collectively shall pay Lender
monthly,  on the first day of each  month,  in arrears,  an
Unused  Line Fee for each month  during the initial  and each 
renewal  Term at the  rate per  annum  set  forth in  Section
10.4(c), calculated upon the amount, if any, by which the
Maximum Credit exceeds the average  outstanding  daily principal
 balance during the preceding month of all Revolving Loans, 
Accommodations and any Term Loan and Capital  Expenditures Loan.

         3.4 At Lender's option,  all principal,  interest
(other than unmatured accrued interest),  fees, costs, expenses
and other charges provided for in this Agreement,  or in any
other agreement now or hereafter  existing  between Lender and
any Borrower, may be charged to any loan account of such
Borrower maintained by Lender. Interest, fees for
Accommodations,  the Unused Line Fee and any other amounts
payable by the Borrowers, or any of them, to Lender based on a
per annum rate shall be  calculated  on the basis of actual 
days  elapsed  over a 360-day year.

         3.5 If as a result of any  regulatory  change  directly
 or  indirectly affecting Lender or any of Lender's affiliated
companies there shall be imposed, modified  or deemed 
applicable  any tax  excluding  any tax on or  measured  by
income, gross receipts,  charges, or rates of Lender, reserve, 
special deposit, minimum capital,  capital ratio, or similar 
requirement against or with respect to  or  measured  by 
reference  to  loans  made  or  to be  made  hereunder  or
participations  therein,  or to  Accommodations,  and  the 
result  shall  be to increase the cost to Lender or to any of
Lender's affiliated companies of making or  maintaining  any 
loan or  Accommodation  hereunder  or to any  other  party
maintaining  any  participation  therein,  or reduce  any amount
 receivable  in respect  of any such  loan  (which  increase  in
cost,  or  reduction  in amount receivable,  shall be the result
of Lender's or Lender's  affiliated  companies' reasonable 
allocation  among all affected  customers  of the  aggregate of
such increases or reductions  resulting from such event),  then,
within ten (10) days after  receipt by the  Borrowers of a 
certificate  from Lender  containing  the information  described
in this Section 3.5,  each Borrower  agrees,  jointly and
severally,  from time to time to pay Lender such additional 
amounts as shall be sufficient to compensate Lender or any of
Lender's affiliated companies for such increased  costs or
reductions  in amounts  which Lender  determines in its sole
discretion are material.  Notwithstanding the foregoing,  all
such amounts shall be  subject  to the  provisions  of  Section 
3.1.  The  certificate  requesting compensation  under this
Section 3.5 shall identify the regulatory  change which has 
occurred,  the  requirements  which have been  imposed, 
modified or deemed applicable,  the  amount of such  additional 
cost or  reduction  in the  amount receivable and the way in
which such amount has been calculated.

         3.6 For  purposes  of  calculating  any  interest, 
fees,  balances  or expenses  hereunder,  the outstanding  daily
principal  balance of the Revolving Loans  will be  deemed  to
be zero  in the  event  that  the  outstanding  daily principal
balance of the Revolving Loans is a credit balance.

SECTION 4. GRANT OF SECURITY INTEREST

         4.1 To secure the payment and  performance in full of
all  Obligations, each Borrower hereby grants to Lender a
continuing security interest in and lien upon,  and a right of
setoff  against,  and each  Borrower  hereby  assigns  and
pledges to Lender,  all of the  Collateral,  including any
Collateral not deemed eligible for lending purposes.

         4.2  "Obligations"  shall mean any and all Revolving
Loans, Term Loans, Accommodations and all other indebtedness, 
liabilities and obligations of every kind,  nature  and 
description  owing by any  Borrower  to  Lender  and/or  its

                                                        11

endorser,  guarantor or  otherwise, whether  arising  under this
 Agreement  or  otherwise,  whether now existing or hereafter 
arising,  whether arising before,  during or after the initial
or any renewal Term or after the  commencement of any case with
respect to any Borrower under the United States  Bankruptcy Code
or any similar statute,  whether direct or indirect,  absolute
or contingent,  joint or several, due or not due, primary or 
secondary,  liquidated  or  unliquidated,  secured or 
unsecured,  original, renewed or extended and whether arising
directly or howsoever acquired by Lender including  from  any 
other  entity  outright,  conditionally  or as  collateral
security,  by  assignment,  merger  with any  other  entity, 
participations  or interests of Lender in the  obligations of
such Borrower to others,  assumption, operation of law, 
subrogation  or otherwise  and shall also include all amounts
chargeable to the Borrowers  under this  Agreement or in
connection  with any of the foregoing.

         4.3  "Collateral"  shall  mean all of the  following 
property  of each Borrower:

         All now owned and hereafter  acquired right, title and
interest of each Borrower in, to and in respect of all:

processes,  drawings, blueprints, customer lists, licenses,

claims,  and  existing  and  future  leasehold  interests  in
equipment, real estate and fixtures); documents; instruments;
letters of credit, bankers'  acceptances or guaranties;  cash
monies,  deposits,  securities,  bank accounts, deposit
accounts,  investment property, credits and other property now

         All now owned and hereafter  acquired right, title and

Borrower's business;  and all names or marks affixed to or to be
affixed thereto for  purposes of selling  same by the seller, 
manufacturer,  lessor or licensor thereof;

         All  equipment  and fixtures,  wherever  located, 
whether now owned or hereafter acquired,  including,  without
limitation,  all machinery,  equipment, motor   vehicles,

                                       12





         All now owned and hereafter acquired right, title and
interests of each Borrower in, to and in respect of any real or

SECTION 5. COLLECTION AND ADMINISTRATION

         5.1  Borrowers  are  authorized  to collect the 
accounts and any other proceeds of Collateral,  on behalf of and
in trust for Lender, at the Borrowers' expense,  but such 
authority  shall  automatically  terminate  upon an Event of
Default.  Lender may modify or terminate  such  authority at any
time whether or not an Event of Default has occurred and
directly collect the accounts and other monetary  obligations 
included in the Collateral.  Each Borrower shall, at such
Borrower's  expense  and in the manner  requested  by Lender 
from time to time, direct that  remittances and all other
proceeds of accounts and other Collateral shall be (a) sent to a
post  office  box  designated  by  and/or  in the name of Lender
or in the name of such  Borrower,  but as to which  access is 
limited to Lender and/or (b) deposited into a bank account
maintained in the name of Lender and/or a blocked bank account
under  arrangements with the depository bank under which all
funds  deposited  to such  blocked  bank  account  are  required
to be transferred  solely to Lender.  Regardless whether such
account is maintained in the name of the Borrowers,  or any of
them, or the Lender,  the Borrowers  shall bear the risk of loss
of all funds in such  account.  In  connection  therewith, each 
Borrower  shall  execute such post office box and/or  blocked
bank account agreements as Lender shall specify.

         5.2 All Obligations shall be payable at Lender's office
set forth below or at Lender's bank designated in Section
10.6(b) or at such other bank or place as  Lender  may 
expressly  designate  from  time to time for  purposes  of this
Section.  Lender  shall  apply all  proceeds  of  accounts  or
other  Collateral received by Lender and all other  payments in
respect of the  Obligations to the Revolving Loans whether or
not then due or to any other Obligations then due, in whatever 
order  or  manner  Lender  shall  determine.  Lender  shall 
have  the continuing and exclusive right to apply and reverse
and reapply any and all such proceeds  and  payments  to any 
portion of the  Obligations.  For  purposes  of determining 
Accounts  Availability and Net Availability,  remittances and
other payments  with  respect to the  Collateral  and 
Obligations  will be treated as credited  to the  loan  account 
of  the  Borrowers  maintained  by  Lender  and Collateral 
balances to which they relate,  upon the date of Lender's
receipt of advice from  Lender's  bank that such  remittances 
or other  payments have been credited to Lender's  account or in
the case of  remittances  or other  payments received,  directly
in kind by Lender, upon the date of Lender's deposit thereof at
Lender's bank, subject to final payment and collection. In
computing interest charges, the loan account of the Borrowers
maintained by Lender will be credited with remittances and other
payments two (2) Business Days after Lender's receipt of advice
of deposit of remittances  and other  payments in Lender's 
account at Lender's  bank  designated  in  Section  10.6(b)  or 
at  such  other  financial

                                       13



 institution  as Lender may  designate.  "Business  Day" shall
mean any day other than a Saturday or Sunday or any other day on
which  Lender or banks in Chicago, Illinois or New York, New
York are authorized to close.

         5.3 Lender shall render to Borrowers monthly a loan
account  statement. Each statement shall be considered  correct
and binding upon each Borrower as an account stated,  except to
the extent that Lender  receives,  within ninety (90) days after
the mailing of such  statement,  written  notice from any
Borrower of any specific exceptions by such Borrower to that
statement.

         5.4 Lender  may,  at any time,  whether or not an Event
of Default  has occurred,  without  notice to or assent of any
Borrower,  (a) notify any account debtor  that the  accounts 
and  other  Collateral  which  includes  a  monetary obligation 
have been  assigned to Lender by any such  Borrower and that
payment thereof is to be made to the order of and directly to
Lender, (b) send, or cause to be sent by its  designee, 
requests  (which  may  identify  the  sender  by a pseudonym)
for  verification  of accounts and other  Collateral  directly
to any account debtor or any other obligor or any bailee with
respect thereto,  and (c) demand, collect or enforce payment of
any accounts or such other Collateral, but without  any duty to
do so, and Lender  shall not be liable for any,  failure to
collect or enforce  payment  thereof.  At Lender's  request, 
all  invoices  and statements sent to any account debtor, other
obligor or bailee, shall state that the  accounts  and such
other  Collateral  have been  assigned to Lender and are payable
directly and only to Lender.

         5.5 Each Borrower  hereby appoints Lender and any
designee of Lender as such Borrower's attorney-in-fact and
authorizes Lender or such designee, at such Borrower's sole
expense, to exercise at any times in Lender's or such designee's
discretion all or any of the following powers,  which powers of
attorney,  being coupled with an interest,  shall be irrevocable
 until all Obligations have been paid in full: (a) receive,
take, endorse,  assign,  deliver, accept and deposit, in the
name of Lender or such  Borrower,  any and all cash,  checks, 
commercial paper,  drafts,  remittances and other instruments
and documents relating to the Collateral  or the  proceeds 
thereof,  (b) transmit to account  debtors,  other obligors or
any bailees  notice of the interest of Lender in the  Collateral
 or request from account  debtors or such other  obligors or
bailees at any time, in the name of such  Borrower  or Lender or
any  designee  of  Lender,  information concerning the
Collateral and any amounts owing with respect thereto, (c)
notify account debtors or other obligors to make payment
directly to Lender,  or notify bailees as to the  disposition of
Collateral,  (d) after an Event of Default has occurred  and has
not been  waived or cured to  Lender's  satisfaction,  take or
bring,  in the name of Lender or such  Borrower,  all steps, 
actions,  suits or proceedings  deemed by Lender necessary or
desirable to effect  collection of or other realization upon the
accounts and other Collateral,  (e) after an Event of Default
has occurred and has not been waived or cured to Lender's 
satisfaction, change the address for delivery of mail to such
Borrower and to receive and open mail addressed to any such
Borrower,  (f) after an Event of Default has occurred and has
not been  waived or cured to Lender's  satisfaction,  extend the
time of payment of, compromise or settle for cash,  credit, 
return of merchandise,  and upon any terms or  conditions,  any
and all accounts or other  Collateral  which includes a monetary
 obligation  and discharge or release the account  debtor or
other obligor, without affecting any of the Obligations,  and
(g) execute in the name of such  Borrower  and file  against 
such  Borrower  in  favor  of  Lender financing statements or
amendments with respect to the Collateral.

         5.6 Each Borrower hereby releases and exculpates 
Lender, its officers, employees and  designees,  from any 
liability  arising from any acts under this Agreement or in
furtherance  thereof,  whether as attorney-in-fact or otherwise,

                                       14



 whether of omission or commission,  and whether based upon any
error of judgment or mistake of law or fact, except for willful
misconduct,  gross negligence,  or bad faith.  In no event will
Lender have any  liability to any Borrower for lost profits or
other special or consequential damages.

         5.7 After written notice by Lender to the Borrowers and
 automatically, without notice,  after an Event of Default which
has not been waived or cured to Lender's  satisfaction,  no
Borrower shall, without the prior written consent of Lender in
each  instance,  (a) grant any  extension of time of payment of
any of the accounts or any other Collateral which includes a
monetary  obligation,  (b) compromise or settle any of the
accounts or any such other  Collateral  for less than the full
amount thereof, (c) release in whole or in part any account
debtor or other person  liable for the payment of any of the
accounts or any such other Collateral, or (d) grant any credits,
discounts, allowances,  deductions, return authorizations or the
like with respect to any of the accounts or any such other
Collateral.

         5.8 At such times as Lender may  reasonably  request 
and in the manner specified  by  Lender,  each  Borrower  shall 
deliver  to  Lender  or  Lender's representative true and
correct copies of original invoices,  agreements, proofs of
rendition of services and delivery of goods and other documents
evidencing or relating to the  transactions  which gave rise to
accounts or other  Collateral, together with customer 
statements,  schedules  describing the accounts or other
Collateral and/or  statements of account and confirmatory 
assignments to Lender of  the  accounts  or  other  Collateral, 
 in  form  and  substance  reasonably satisfactory  to Lender
and duly  executed by such  Borrower.  After an Event of Default
has occurred, each Borrower shall deliver to Lender the
originals of the foregoing  documents  upon  Lender's  request 
therefor.  Without  limiting  the provisions  of  Section  5.7, 
a  Borrower's  granting  of  credits,  discounts, allowances, 
deductions,  return  authorizations  or the like  will be 
promptly reported  to  Lender  in  writing.  In no  event  shall
 any  such  schedule  or confirmatory  assignment  (or the 
absence  thereof  or  omission  of any of the accounts or other 
Collateral  therefrom)  limit or in any way be construed as a
waiver, limitation or modification of the security interests or
rights of Lender or the  warranties,  representations  and 
covenants of any Borrower  under this Agreement. Any documents,
schedules, invoices or other paper delivered to Lender by the 
Borrowers  may be destroyed  or otherwise  disposed of by Lender
six (6) months after receipt by Lender,  unless such Borrower 
requests  their return in writing in  advance,  and makes prior 
arrangements  for their  return,  at such Borrower's expense.

         5.9 From time to time as  requested  by Lender,  at the
sole expense of the Borrowers,  Lender or its designee  shall
have access,  prior to an Event of Default during reasonable 
business hours and on or after an Event of Default at any time,
to all of the premises where Collateral is located for the
purposes of inspecting  the  Collateral  and all  Borrowers' 
books  and  records,  and each Borrower  shall permit  Lender or
its designee to make such copies of such books and records or
extracts  therefrom  as Lender may  reasonably  request. 
Without expense to Lender, Lender may use such of any Borrower's
 personnel,  equipment, including  computer  equipment, 
programs,  printed output and computer readable media,  supplies
and premises for the collection of accounts and  realization on
other Collateral as Lender,  in its sole  discretion,  deems 
appropriate.  Each Borrower  hereby  irrevocably  authorizes all
 accountants  and third parties to disclose  and  deliver  to 
Lender  at such  Borrower's  expense  all  financial
information,  books and  records,  work  papers,  management 
reports  and other information in their possession regarding
such Borrower.

                                       15





         5.10 If after  receipt of any payment  of, or  proceeds
 applied to the payment  of,  all or any part of the 
Obligations,  the Lender is for any reason required to surrender
such payment or proceeds  because such payment or proceeds is 
invalidated,  declared  fraudulent,  set  aside,  determined  to
be  void or voidable  as a  preference,  or a  diversion  of
trust  funds,  or for any other reason, then: the Obligations or
any part thereof intended to be satisfied shall be revived and
continue and this  Agreement  shall  continue in full force as
if such payment or proceeds had not been received by the Lender,
 and each Borrower shall be jointly  and  severally  liable to
pay to the  Lender,  and hereby does indemnify  the  Lender  and
hold the  Lender  harmless,  for the  amount of such payment or
proceeds  surrendered.  The  provisions of this Section 5.10
shall be and remain  effective  notwithstanding  any contrary 
action which may have been taken by the Lender in  reliance 
upon such  payment or  proceeds,  and any such contrary action
so taken shall be without prejudice to the Lender's rights under
this Agreement and shall be deemed to have been conditioned upon
such payment or proceeds  having become final and  irrevocable. 
The  provisions of this Section 5.10 shall survive the
termination of this Agreement.

SECTION 6. ADDITIONAL REPRESENTATIONS, WARRANTIES AND COVENANTS

         Each Borrower hereby  represents,  warrants and
covenants to Lender the following,  the truth and accuracy of
which, and compliance with which, shall be continuing 
conditions of the making of loans or other credit 
accommodations by Lender to any Borrower:

         6.1 Each  Borrower  shall keep and  maintain  its books
and  records in accordance with generally accepted accounting
principles,  consistently applied. The Borrowers shall on a
consolidated  basis, at each Borrower's  expense, on or before
the  fifteenth  (15th)  day of each  month,  deliver  to Lender 
true and complete  monthly  agings of its  accounts  receivable 
and,  on or  before  the twentieth  (20th) day of each month, 
deliver to Lender true and complete agings of its  accounts  and
notes  payable,  monthly  inventory  reports  and  monthly
internally  prepared  interim  financial  statements   including
  consolidating financial  statements of the Borrowers and any
of the  Borrowers'  subsidiaries, all in such form, and together
with such other  information  with respect to the business of
each Borrower or any guarantor,  as Lender may  reasonably 
request. Quarterly,  the  Borrowers  shall  deliver  to  Lender
a  certificate  verifying Borrowers' compliance with the
financial covenants set forth in Section 6.11 and Section 10.5, 
such  certificate  to be delivered as soon as available but in
no event  later  than  forty-five  (45) days after the end of
the  relevant  fiscal quarter,  provided,  however,  that with 
respect to the  certificate  verifying compliance during the
final fiscal quarter of each fiscal year,  Borrowers shall
deliver such  certificate  to Lender no later than sixty (60)
days after the end of such  fiscal  quarter.  Annually,  the 
Borrowers  shall  deliver  to  Lender consolidated  audited
financial  statements of Key accompanied by the report and
opinion  thereon  of  independent   certified  public  
accountants   reasonably acceptable to Lender and consolidating
financial statements of Borrowers and any of Borrowers' 
subsidiaries,  as soon as  available,  but in no event later
than ninety  (90) days after the end of the  Borrowers'  fiscal 
year.  Additionally, promptly  upon the filing  thereof, 
Borrower  shall  deliver to Lender true and complete copies of
any 10-Q Report, 10-K Report and any other report or document
filed by Borrowers, or any of them, with the Securities and
Exchange Commission, or any other governmental agency.

         6.2 Each  Borrower  may from time to time  render 
invoices  to account debtors  under its trade  names set forth
in Section  10.6(f)  after  Lender has received  prior written
notice from such Borrower of the use of such trade names and as
to which,  such Borrower  agrees that: (a) each trade name does
not refer

                                       16





to another  corporation  or other legal  entity,  (b) all 
accounts and proceeds thereof (including any returned
merchandise) invoiced under any such trade names are owned 
exclusively by such Borrower and are subject to the security
interest of Lender  and the  other  terms of this  Agreement, 
and (c) all  schedules  of accounts  and  confirmatory 
assignments  including  any sales made or  services rendered 
using the trade name shall show such  Borrower's  name as
assignor and Lender is authorized to receive, endorse and
deposit to any loan account of such Borrower  maintained by
Lender all checks or other  remittances  made payable to any
trade name of such Borrower  representing payment with respect
to such sales or services.

         6.3 Each Borrower shall promptly  notify Lender in
writing of any loss, damage, investigation,  action, suit,
proceeding or claim relating to a material portion of the
Collateral or which may result in any material  adverse change
in such  Borrower's  business,  assets,  liabilities  or 
condition,  financial  or otherwise.

         6.4 Each Borrower's books and records concerning
accounts and its chief executive  office are and shall be 
maintained  only at the address set forth in Section  10.6(d). 
Each  Borrower's  only other  places of business and the only
other locations of Collateral,  if any, are and shall be the
addresses set forth in Section 10.6(e) hereof,  except any
Borrower may change such locations in the ordinary  course of
business or open a new place of business  after  thirty (30)
days prior written notice to Lender.  Prior to any change in
location or opening of any new place of business,  each Borrower
 shall execute and deliver or cause to be executed and 
delivered  to Lender such  financing  statements,  financing
documents, mortgages, and security and other agreements as
Lender may reasonably require, including, without limitation,
those described in Section 6.14. Without otherwise limiting the
effect of the foregoing, Borrower may change the location of its
well  servicing  rigs and drilling rigs without prior approval
of Lender; provided, however, such well servicing rigs and
drilling rigs may not be removed from the state where they are
located as of the date hereof, and Borrowers shall within five
(5) days of Lender's  request,  provide Lender with a listing of
the current locations of all well servicing rigs and drilling
rigs.

         6.5 Each  Borrower has and at all times will  continue
to have good and marketable title to all of the Collateral, free
and clear of all liens, security interests, claims or
encumbrances of any kind except those, if any, set forth on
Schedule A hereto.

         6.6  No  Borrower  shall  directly  or  indirectly: 
(a)  sell,  lease, transfer,  assign, abandon or otherwise
dispose of any part of the Collateral or any  material  portion
of its other  assets  (other than sales of  inventory  to buyers
in the ordinary course of business) or (b) consolidate with or
merge with or into any other  entity,  or permit any other 
entity to  consolidate  with or merge with or into such 
Borrower  or (c) form or acquire  any  interest  in any firm,
corporation or other entity.

         6.7 Each Borrower shall at all times maintain,  with
financially  sound and reputable  insurers,  casualty  insurance
with respect to the Collateral and other assets.  All such 
insurance  policies  shall be in such form,  substance, amounts 
and  coverage  as may be  reasonably  satisfactory  to Lender
and shall provide for thirty (30) days prior written notice to
Lender of  cancellation  or reduction of coverage.  Each
Borrower hereby irrevocably appoints Lender and any designee  of
Lender as,  attorney-in-fact  for such  Borrower  to obtain at
such Borrower's  expense,  any such insurance should such
Borrower fail to do so and, after an Event of Default that is 
continuing,  to adjust or settle any claim or other matter under
or arising pursuant to such insurance or to amend or cancel

                                       17





such insurance. Each Borrower shall deliver to Lender evidence
of such insurance and a  lender's  loss  payable  endorsement 
satisfactory  to  Lender  as to all existing and future 
insurance  policies  with respect to the  Collateral.  Each
Borrower shall deliver to Lender, in kind, all instruments
representing proceeds of insurance received by such Borrower.
Prior to an Event of Default, Lender may permit  Borrowers to
apply any  insurance  proceeds  received at any time to the cost
of repairs to or replacement of any portion of the  Collateral 
and/or,  at Lender's option,  payment of or as security for any
of the Obligations,  whether or not due;  provided,  however, 
that if Lender  elects to apply the  insurance proceeds to the
then outstanding Obligations, Lender will apply the proceeds (i)
first to reduce the Capital  Expenditures  Loans,  (ii) second, 
to reduce other Term Loans, and (iii) third, to reduce the
Revolving Loans. After the occurrence of an Event of Default
which has not been cured to Lender's satisfaction, Lender may
permit Borrowers to apply any insurance proceeds received at any
time to the cost of repairs to or replacement of any portion of
the  Collateral  and/or,  at Lender's  option,  to  payment  of
or as  security  for any of the  Obligations, whether or not
due, in any order or manner as Lender determines.

         6.8 Each Borrower is and at all times will continue to
be in compliance with the requirements of all material laws,
rules, regulations and orders of any governmental   authority 
relating  to  its  business  (including  laws,  rules,
regulations  and orders  relating to taxes,  payment and 
withholding of payroll taxes,  employer  and  employee 
contributions  and similar  items,  securities, employee 
retirement  and  welfare  benefits,  employee  health and 
safety,  or environmental matters) and all material agreements
or other instruments, binding on such  Borrower or its property.
 All of each  Borrower's  inventory  shall be produced in
accordance with the requirements of the Federal Fair Labor
Standards Act of 1938, as amended and all rules,  regulations
and orders related  thereto. Each Borrower shall pay and
discharge all taxes,  assessments  and  governmental charges 
against  such  Borrower  or any  Collateral  prior to the date
on which penalties are imposed or liens attach with respect
thereto, unless the, same are being contested in good faith and,
at Lender's option,  Reserves are established for the amount
contested and penalties which may accrue thereon.

         6.9 With respect to each account deemed an Eligible
Account,  except as reported in writing to Lender,  (a) Borrower
 has no  knowledge  that any of the criteria for eligibility are
not or are no longer  satisfied,  (b) each is valid and legally 
enforceable  and  represents an undisputed  bona fide 
indebtedness incurred by the account  debtor for the sum
reported to Lender,  (c) each arises from an absolute and
unconditional sale of goods, without any right of return or
consignment,  or from a completed rendition of services, (d)
each is not, at the time such  account  arises,  subject to any 
defense,  offset,  dispute,  contra relationship,  counterclaim,
 or any  given  or  claimed  credit,  allowance  or discount 
except as  disclosed  to Lender in writing  and  approved by
Lender in writing,  and  (e) all  statements  made  and  all 
unpaid  balances  and  other information  appearing  in the 
invoices,  agreements,  proofs of  rendition  of services and
delivery of goods and other documentation relating to the
accounts, and all confirmatory assignments, schedules,
statements of account and books and records with respect
thereto,  are in all material respects true and correct and what
they purport to be.

         6.10 With  respect to each  Borrower's  equipment, 
each such  Borrower shall maintain  equipment  having an
aggregate value of at least 85% of the then current appraised
forced  liquidation value of all of such Borrower's  equipment
in good order and repair, and in running and marketable
condition, ordinary wear and tear excepted.

                                       18





         6.11 Borrowers shall at all times on a consolidated
basis maintain cash flow coverage,  tangible net worth, and
liabilities to tangible net worth as set forth in Section 10.5
and no Borrower shall,  directly or indirectly,  expend or
commit  to  expend,  for  fixed  or  capital  assets  (including
 capital  lease obligations) an amount in excess of the capital 
expenditure  limit set forth in Section 10.5 in any fiscal year
of  Borrowers.  In  addition,  after the date of this  Agreement
no Borrower  will enter into any  operating or capital  lease as
lessee or sublessee if, after giving  effect  thereto,  the
aggregate  amount of additional  operating or capital lease 
rentals  payable by all Borrowers in any fiscal  year with 
respect to all such leases  entered  into in such fiscal year
would exceed $1,500,000.

         6.12  Except as set forth on  Schedule  6.12  hereto 
and as  otherwise provided herein, no Borrower will,  directly
or indirectly:  (a) lend or advance money or property to,
guarantee or assume indebtedness of, or invest (by capital
contribution or otherwise) in any person, firm,  corporation or
other entity; or (b) declare, pay or make any cash dividend, 
redemption or other distribution on account of any shares of any
class of stock of such  Borrower  now or  hereafter outstanding;
 or (c) make any payment of the principal  amount of or interest
on any indebtedness owing to any officer,  director, 
shareholder,  or affiliate of such  Borrower;  or (d) make any
loans or  advances  to any  officer,  director, employee, 
shareholder or affiliate of such Borrower (including, but not
limited to, any other  Borrower)  provided,  however,  that,
with respect to advances to officers and employees,  Borrowers
may make such advances in the ordinary course of business as
long as all such advances at any time  outstanding  do not
exceed $25,000 in the aggregate during any fiscal year of
Borrowers;  or (e) enter into any sale or lease or other 
transaction  with any officer,  director,  employee, shareholder
 or affiliate of such  Borrower on terms that are less 
favorable to such  Borrower  than those which might be obtained
at the time from  persons who are  not an  officer,  director, 
employee,  shareholder  or  affiliate  of such Borrower. 
Notwithstanding the foregoing,  each Borrower (each, an
"Intercompany Lender") may make loans to any other Borrower
(each, an "Intercompany Borrower") provided however that (i) all
such loans to any  Intercompany  Borrower shall be evidenced  by
the  Intercompany  Note and  Security  Agreement  executed by
such Intercompany  Borrower (the "Chattel  Paper") and (ii)
Lender retains a properly perfected   security  interest  in 
the  Chattel  Paper  at  the  time  of  such intercompany  loan.
 In  addition,  WellTech  may  make  intercompany  loans  to
WellTech's 63% owned subsidiary,  Servicios WellTech, S.A.
("Servicios") as long as (a) all such intercompany  loans are
properly  documented on WellTech's books and records,  (b) all
such  intercompany  loans are  memorialized by one or more
Intercompany Note and Security  Agreements (the "Servicios
Chattel Paper"),  (c) no such additional  intercompany loans to
Servicios after January 19, 1996 would exceed the amount of
$500,000 which is part of the principal amount as set forth in
the related Intercompany Note and Security Agreement executed by
Servicios of even date  herewith,  and (d)  Lender  retains  a 
properly  perfected  security interest in the Servicios Chattel
Paper at the time of such intercompany loan.

         6.13 Each Borrower shall pay, on Lender's demand, all
costs,  expenses, filing fees and taxes payable in  connection 
with the  preparation,  execution, delivery, recording, 
administration,  collection, liquidation,  enforcement and
defense of the  Obligations,  Lender's rights in the Collateral,
 this Agreement and all other existing and future agreements or
documents contemplated herein or related hereto, including any
amendments, waivers, supplements or consents which may hereafter
be made or entered into in respect hereof, or in any way
involving claims or  defense  asserted  by Lender or  claims  or
 defense  against  Lender asserted  by such  Borrower,  any 
guarantor  or any  third  party  directly  or indirectly 
arising out of or related to the relationship  between such
Borrower and  Lender or any  guarantor  and  Lender,  including,
 but not  limited to the

                                       19



 following,  whether incurred before,  during or after the
initial or any renewal Term or after the  commencement of any
case with respect to any such Borrower or any guarantor under
the United States  Bankruptcy  Code or any similar  statute: (a)
all costs and expenses of filing or recording  (including
Uniform Commercial Code financing statement filing taxes and
fees,  documentary taxes,  intangibles taxes and  mortgage 
recording  taxes and fees,  if  applicable);  (b) all title
insurance  and other  insurance  premiums,  appraisal  fees, 
fees  incurred  in connection with any environmental  report, 
audit or survey and search fees; (c) all fees relating to the
wire transfer of loan proceeds and other funds and fees for
returned checks;  (d) all reasonable  expenses and costs
heretofore and from time to time  hereafter  incurred by Lender
during the course of periodic  field examinations  of the
Collateral and the Borrowers'  operations,  plus a per diem
charge at the rate of $650 per person,  per day for  Lender's 
examiners  in the field and  office;  and (e) the  reasonable 
costs,  fees and  disbursements  of in-house and outside counsel
to Lender.

         6.14 At the  request  of  Lender,  at any time and from
time to time at such Borrower's  sole expense,  each Borrower
shall execute and deliver or cause to  be  executed  and 
delivered  to  Lender  such  agreements,   documents  and
instruments,  including  waivers,  consents and  subordination 
agreements  from mortgagees  or other  holders  of  security 
interests  or liens,  landlords  or bailees,  and do or  cause 
to be  done  such  further  acts as  Lender,  in its discretion,
 deems  necessary  or  desirable  to  create,  preserve, 
perfect or validate  any  security  interest  of  Lender  or the
 priority  thereof  in the Collateral  and  otherwise to 
effectuate  the  provisions  and purposes of this Agreement. 
Each Borrower hereby authorizes Lender to file financing 
statements or  amendments  against  such  Borrower in favor of
Lender  with  respect to the Collateral,   without  such 
Borrower's  signature  and  to  file  as  financing statements
any carbon,  photographic or other reproductions of this
Agreement or any financing statements signed by such Borrower.

         6.15  Each  Borrower   authorizes   Lender,   at 
Lender's  option,  as attorney-in-fact  for such Borrower,  to
commence,  appear in and prosecute,  in Lender's or such 
Borrower's name and with the  participation  of such Borrower,
any action or  proceeding  relating to any  condemnation  or
other taking of any Collateral  comprised of real property and
to settle or compromise  any claim in connection with any such
condemnation or other taking.  Any award for the taking of, or
damage to, all or any part of the  Collateral,  or any interest 
therein, upon the lawful  exercise of power of eminent  domain
shall be payable to Lender who, after deducting its expenses, 
including  reasonable  attorneys'  fees, may apply the sums so
received to the portion of the Obligations hereby secured last
falling due or in such other manner as Lender may desire.  Each
Borrower  agrees to execute such  further  assignments  of any 
compensations,  awards,  damages, claims, rights of action and
proceeds as Lender reasonably may require.

         6.16 Each Borrower  assumes all  responsibility  and
liability  arising from or relating  to the use,  sale,  or
other  disposition  of the  Collateral. Neither the Lender nor
any of its  officers,  directors,  employees,  and agents shall
be  liable or  responsible  in any way for the  safekeeping  of
any of the Collateral,  or for any act or failure to act with
respect to the Collateral, or for any loss or damage thereto, 
or for any diminution in the value thereof,  or for any act of
default by any warehouseman, carrier, forwarding agency or,
other person  whomsoever,  all of which  shall be at the 
Borrowers'  sole  risk.  The Obligations shall not be affected
by any failure of the Lender to take any steps to  perfect  its 
security  interest  in or  to  collect  or  realize  upon  the
Collateral,  nor shall loss of or damage to the Collateral 
release any Borrower from any of the  Obligations.  The Lender
may (but shall not be required to), to the extent set forth in
this Agreement or applicable  law,  without notice to or

                                       20



 consent from any Borrower,  sue upon or otherwise  collect, 
extend the time for payment  of,  modify or amend the terms  of,
 compromise  or settle  for cash or credit,  grant  other 
indulgences,   extensions,   renewals,  compositions,  or
releases,  and  take or omit  to take  any  other  action  with 
respect  to the Collateral, any security therefor, any agreement
relating thereto, any insurance applicable  thereto,  or any
person liable  directly or indirectly in connection with any of
the  foregoing,  without  discharging  or  otherwise  affecting 
the liability of the Borrower for the Obligations.

         6.17 Each  Borrower  shall  notify  Lender in writing
of the  following matters at the following times:

               (a)  Immediately  after  becoming  aware of the 
existence of any          Event of Default.

               (b)  Immediately  after  becoming  aware  that
the  holder of any          capital  stock of such  Borrower 
has given notice or taken any action          with respect to a
claimed default.

               (c)  Immediately  after  becoming  aware of any
material  adverse          change in the  Collateral  or in any 
Borrower's  property,  business,          operations, or
condition (financial or otherwise).

               (d) Immediately after becoming aware of any
pending or threatened          action,   proceeding,   or 
counterclaim   by  any  individual,   sole         
proprietorship,  partnership,  joint  venture,  trust, 
unincorporated          organization, association, corporation,
Public Authority, or any other          entity,  or  any 
pending  or  threatened  investigation  by a  Public         
Authority,  which may materially and adversely  affect the
Collateral,          the repayment of the  Obligations,  the
Lender's rights under the Loan          Documents, or the
Collateral or in any Borrower's property,  business,         
operations, or condition (financial or otherwise).

               (e) Immediately after becoming aware of any
pending or threatened          strike, work stoppage,  material
unfair labor practice claim, or other          material   labor 
dispute   affecting  any  Borrower  or  any  of  its         
subsidiaries.

               (f) Immediately after becoming aware of any
violation of any law,          statute,  regulation, or
ordinance of a Public Authority applicable to          any 
Borrower,   which  may  materially   and  adversely   affect 
the          Collateral,  the  repayment of the  Obligations, 
the Lender's  rights          under this  Agreement,  or the
Collateral or any Borrower's  property,          business,
operations, or condition (financial or otherwise).

               (g)  Immediately  after  becoming  aware of any 
violation or any          investigation  of a violation  by any
Borrower of  environmental  laws          which  would 
materially  and  adversely  affect the  Collateral,  any        
 Borrower's  property,  business,  operation or condition
(financial or          otherwise).

               (h) Thirty (30) days prior to any Borrower
changing its name.

Each notice  given under this Section  6.17 shall  describe  the

any other site or vessel at any time  owned,  occupied,  or

Borrower,  or by any person for         whose conduct any 
Borrower,  or any  subsidiary  of any  Borrower,  is        
responsible,  where such release or threat of release is
required to be         reported  to  any  governmental  
authority  by  any  Borrower  or  any         subsidiary of any
Borrower or any other such person, or may result in a        
lien  on  the  Premises  or  other  property  of  any  Borrower 
or any         subsidiary of any Borrower;  (y) upon any 
Borrower's or any Borrower's         subsidiary's  receipt of
any notice to such  effect  from any  federal,         state, 
foreign  or  other  governmental  authority;  and (z)  upon any 
       Borrower's or any Borrower's  subsidiary's  obtaining 
knowledge of any         incurrence of any expense or loss by
any such governmental authority in         connection  with  the
 assessment,   containment,  or  removal  of  any        
hazardous material or oil for which expense or loss any Borrower

or for which expense a         lien may be  imposed  on the

any subsidiary of any Borrower; and

                  (v) jointly and  severally  indemnify,  defend
and hold Lender         harmless  from any claim brought or 
threatened  against  Lender by any         Borrower, or any
subsidiary of any Borrower,  any guarantor or endorser        
of the Obligations, or any governmental agency or authority or
any

                                       23





         other person (as well as from  attorneys'  and 
environmental  expert's         reasonable fees and expenses in
connection therewith) on account of the         presence of 
hazardous  material or oil on the  Premises,  or any other      
  site or vessel at any time owned,  occupied or operated by any
Borrower         or any  subsidiary  of any Borrower or any
person for whose conduct any         Borrower or any subsidiary
of any Borrower may be responsible, or whose         liability
may result in a lien on the Premises or other property of any   
     Borrower or any subsidiary of any Borrower, the past,
present or future         release or threat of release of 
hazardous  materials or oil on or from         the Premises,  or
any other site or vessel at any time owned,  occupied         or
operated by any Borrower,  or any subsidiary of any Borrower, 
or by         any person for whose  conduct  any  Borrower or
any  subsidiary  of any         Borrower may be responsible or
whose  liability may result in a lien on         the Premises or
other property of any Borrower or any subsidiary of any        
Borrower,  or the failure by any  Borrower to comply with the
terms and         provisions  of this  Section  6.18  (each  of 
which  may be  defended,         compromised,  settled,  or
pursued by Lender  with  counsel of Lender's         selection, 
but at the expense of the Borrowers, on a joint and several     
   basis,  and, in the case of compromise or settlement  prior
to an Event         of Default, with the consent of any
Borrower,  which consent shall bind         all Borrowers). The
within indemnification shall survive payment of the        
Obligations and/or any termination,  release,  or discharge
executed by         Lender in favor of any  Borrower or any 
subsidiary  of any Borrower or         other person.

         (e) As used in this Section 6.18,  the term "oil" shall
mean oil and/or any other petroleum product or by-product.

         6.19 At Lender's  option,  and at each Borrower's 
expense,  Lender may order  appraisals of the forced 
liquidation  value of Borrower's  machinery and equipment, 
provided, however, that the timing and manner of all such
appraisals shall be commercially  reasonable in all respects. 
If the principal  balance of the Term Loans  outstanding  to any
Borrower,  as of the date of the  appraisal, exceeds  eighty-two
 percent (82%) of the appraised forced  liquidation value of
such  Borrower's  machinery and equipment,  such Borrower shall
make  additional principal  payments  with respect to the Term
Loan in an amount equal to 1/12 of the amount by which the 
outstanding  principal  balance of such Borrower's Term Loans
exceeds eighty-two percent (82%) of the appraised forced
liquidation value of such Borrower's machinery and equipment as
of the date of the appraisal, such payments to be paid 
concurrently  with the monthly Term Loan  installments  due
under the Term Loans, until the entire excess amount has been
fully amortized.

         6.20 No Borrower shall  directly or indirectly  enter
into or permit to exist,  any  transaction  with  Odessa as 
obligor to such  Borrower,  direct or contingent,  by reason  of
any loan,  advance,  lease,  sale or other  financing
transaction,  investment or otherwise;  provided, however, that
Hurt may provide services  from  time to time to  Odessa  as
long as the  aggregate  of all  such accounts outstanding at any
time does not exceed $300,000.00.

SECTION 7. EVENTS OF DEFAULT AND REMEDIES

         7.1 All  Obligations  shall be  immediately  due and 
payable,  without notice or demand,  and any  provisions of this
 Agreement as to future loans and credit  accommodations  by 
Lender  shall  terminate  automatically,   upon  the termination
or non-renewal of this Agreement or, at Lender's option,  upon
or at any time after the  occurrence  or existence of any one or
more of the following "Events of Default":

or misleading in any material respect;

         (f) Any  change in the chief  executive  officer  or

                                       25





         (j) Any  event  of  default  under  any  financing,

executed and/or delivered to, with or in favor of Lender or any
of its affiliates by any affiliate of any Borrower;

         (k) Lender in good faith  believes  that  either  (i)
the  prospect  of payment or performance of the  Obligations is
impaired or (ii) the Collateral is not sufficient to secure
fully the Obligations; or

         (l) Any  default  by any  Borrower  under  any 
material  agreement  or instrument,  in favor of any  individual
 or entity  other than  Lender and such default continues for
thirty (30) days after such breach first occurs; provided,
however,  that such grace period shall not apply,  and an Event
of Default shall exist, promptly upon such breach, if such
breach may not, in Lender's reasonable determination, be cured
by Borrower during such thirty (30) day grace period.

         7.2 Upon the  occurrence  of an Event  of  Default 
which  has not been waived by Lender or cured to Lender's 
satisfaction  and at any time thereafter, Lender shall have all
rights and remedies provided in this Agreement,  any other
agreements between any Borrower and Lender, the Uniform
Commercial Code or other applicable law, all of which rights and
remedies may be exercised without notice to any Borrower,  all
such notices being hereby waived, except such notice as is
expressly  provided for hereunder or is not waivable under 
applicable  law. All rights  and  remedies  of  Lender  are 
cumulative  and  not  exclusive  and are enforceable,   in  
Lender's   discretion,   alternatively,   successively,   or
concurrently on any one or more occasions and in any order
Lender may determine. Without  limiting the  foregoing,  Lender
may (a)  accelerate the payment of all Obligations and demand 
immediate  payment thereof to Lender,  (b) to the extent
permitted by law, with or without  judicial  process or the aid
or assistance of others,  enter upon any  premises  on or in
which any of the  Collateral  may be located  and  take  
possession  of  the  Collateral  or  complete   processing,
manufacturing and repair of all or any portion,  of the
Collateral,  (c) require any Borrower,  at such  Borrower's 
expense,  to assemble and make  available to Lender any part or
all of the  Collateral  at any place and time  designated  by
Lender, (d) collect, foreclose,  receive,  appropriate, set off
and realize upon any and all Collateral,  (e) extend the time of
payment of, compromise or settle for cash, credit, return of
merchandise,  and upon any terms or conditions,  any and all
accounts or other  Collateral  which includes a monetary 
obligation and discharge or release the account debtor or other
obligor,  without affecting any of the Obligations,  (f) sell, 
lease,  transfer,  assign,  deliver or otherwise dispose of any
and all Collateral (including, without limitation,  entering
into contracts  with respect  thereto,  by public or private 
sales at any  exchange, broker's  board,  any office of Lender
or  elsewhere) at such prices or terms as Lender may deem
reasonable,  for cash, upon credit or for future delivery,  with
the Lender having the right to purchase the whole or any part of
the  Collateral at any such  public  sale,  all of the 
foregoing  being  free from any right or equity of  redemption 
of any Borrower  which right or equity of  redemption  is hereby
expressly waived and released by each Borrower.  If any of the
Collateral is sold or  leased by Lender  upon  credit  terms or
for  future  delivery,  the Obligations  shall not be reduced as
a result thereof until payment  therefor is finally  collected
by Lender. If notice of disposition of Collateral is required by
law,  ten  (10)  business  days  prior  notice  by  Lender  to
the  Borrowers designating  the time and place of any public 
sale or the time after  which any private sale or other intended
disposition of Collateral is to be made, shall be deemed to be 
reasonable  notice  thereof  and each  Borrower  waives  any
other notice.  In the event Lender  institutes an action to
recover any  Collateral or seeks  recovery of any Collateral by
way of  prejudgment  remedy,  each Borrower waives to the 
extent  permitted  by law the  posting  of any bond  which 
might otherwise be required.

                                       26



         7.3 Lender may apply the cash proceeds of Collateral 
actually received by  Lender  from  any  sale,  lease, 
foreclosure  or other  disposition  of the Collateral to payment
of any of the Obligations,  in whole or in part (including
reasonable  attorneys'  fees and legal expenses  incurred by
Lender with respect thereto or otherwise  chargeable to the 
Borrowers)  and in such order as Lender may elect,  whether or
not then due. Each Borrower shall remain liable to Lender for
the payment of any  deficiency  together  with  interest at the
highest rate provided for herein and all costs and  expenses of 
collection  or  enforcement, including reasonable attorneys'
fees and legal expenses.

         7.4 Lender may, at its option,  cure any default by any
Borrower  under any agreement  with a third party or pay or bond
on appeal any judgment  entered against any  Borrower, 
discharge  taxes,  liens,  security  interests  or other
encumbrances  at any time levied on or existing  with respect to
the  Collateral and pay any amount, incur any expense or perform
any act which, in Lender's sole judgment, is necessary or
appropriate to preserve,  protect, insure, maintain or realize
upon the  Collateral.  Lender may charge the Borrowers' loan
account for any amounts so  expended,  such  amounts to be 
repayable  by the  Borrowers  on demand.  Lender  shall be under
no  obligation  to effect  such  cure,  payment, bonding or 
discharge,  and shall not by doing so, be deemed to have assumed
any obligation or liability of any Borrower.

SECTION 8. JURY TRIAL WAIVER; CERTAIN OTHER WAIVERS AND CONSENTS

         8.1 WAIVER OF JURY  TRIAL.  LENDER AND EACH  BORROWER 
ACKNOWLEDGE  AND AGREE  THAT  ANY  CONTROVERSY  WHICH  MAY 
ARISE  UNDER  THIS  AGREEMENT  OR THE RELATIONSHIP  ESTABLISHED 
HEREBY  WOULD BE BASED  UPON  DIFFICULT  AND  COMPLEX ISSUES, 
AND  THEREFORE,  THE PARTIES AGREE THAT ANY LAWSUIT  GROWING OUT
OF ANY SUCH CONTROVERSY  WILL BE TRIED IN A COURT OF COMPETENT 
JURISDICTION BY A JUDGE SITTING  WITHOUT  JURY.  TRIAL BY A
JUDGE  SITTING  WITHOUT A JURY WILL  FURTHER RESULT IN THE
AVOIDANCE OF DELAYS,  A STREAMLINING OF THE  PROCEEDINGS 
INVOLVED AND, AS A RESULT,  WILL MINIMIZE THE EXPENSE OF ANY
SUCH LAWSUIT FOR THE BENEFIT OF EACH BORROWER AND LENDER.  EACH
BORROWER HEREBY WAIVES TRIAL BY JURY,  RIGHTS OF SET  OFF,  AND
THE  RIGHT  TO  IMPOSE  COUNTERCLAIMS  (EXCEPT  BY  COMPULSORY
COUNTERCLAIMS)  IN ANY  LITIGATION  IN ANY COURT WITH RESPECT
TO, IN  CONNECTION WITH,  OR  ARISING  OUT  OF  THIS  AGREEMENT,
 THE  OTHER  LOAN  DOCUMENTS,  THE OBLIGATIONS OR THE
COLLATERAL,  OR ANY INSTRUMENT OR DOCUMENT DELIVERED PURSUANT
HERETO OR THERETO, OR ANY OTHER CLAIM OR DISPUTE HOWSOEVER
ARISING,  BETWEEN THE BORROWERS,  OR ANY OF THEM, AND THE
LENDER.  EACH BORROWER  HEREBY CONFIRMS THAT THE FOREGOING
WAIVERS ARE INFORMED AND FREELY MADE.

         8.2 Each  Borrower  hereby  irrevocably  submits  and 
consents  to the nonexclusive  jurisdiction  of the State and
Federal Courts located in the State in which the office of
Lender  designated in Section  10.6(a) is located and any other
State where any Collateral is located with respect to any action
or

                                       27





proceeding  arising out of this Agreement,  the Collateral or
any matter arising therefrom or relating thereto.  In any such
action or proceeding,  each Borrower waives personal service of
the summons and complaint or other process and papers therein
and agrees that the service thereof may be made by mail directed
to such Borrower at its chief executive office set forth herein
or other address thereof of which Lender has  received  notice
as provided  herein,  service to be deemed complete  five (5)
days after  mailing by certified or  registered  mail,  or as
permitted  under  the  rules  of  either  of said  Courts.  Any
such  action  or proceeding  commenced by any Borrower against
Lender will be litigated only in a Federal Court located in the
district, or a State Court in the State and County, in which the
office of Lender  designated in Section 10.6(a) is located and
each Borrower waives any objection based on forum non conveniens
and any objection to venue in connection therewith.

         8.3 Lender  shall not,  by any act,  delay,  omission
or  otherwise  be deemed to have  expressly  or  impliedly 
waived any of its  rights or  remedies unless such waiver  shall
be in writing and signed by an  authorized  officer of Lender. 
A waiver by Lender of any right or remedy on any one occasion
shall not be  construed  as a bar to or waiver of any such 
right or remedy  which  Lender would  otherwise  have  on any 
future  occasion,  whether  similar  in  kind or otherwise.

         8.4 Unless otherwise  expressly provided herein,  each
Borrower waives, to the extent permitted by applicable law,
diligence,  presentment,  protest and notice of demand or
dishonor and protest as to any instrument,  notice of intent to
accelerate and notice of acceleration,  notice of default,
notice of protest, demand, dishonor or nonpayment, as well as
any and all other notices to which it might  otherwise be
entitled.  No notice to or demand on any Borrower  which the
Lender may elect to give shall  entitle such  Borrower to any
further  notice or demand in the same, similar or other
circumstances.

         8.5 The  provisions  of Chapter 15 of the Texas  Credit
Code  (Vernon's Texas Civil Statutes)  Article 5069-15 are 
specifically  declared by Lender and the  Borrowers  not to be 
applicable  to  this  Agreement  or the  transactions
contemplated hereby.

SECTION 9. TERM OF AGREEMENT; MISCELLANEOUS

         9.1 Term. This Agreement shall only become effective
upon the execution and delivery of this Agreement by each
Borrower and Lender and shall continue in full force and effect
until either  December  31, 1998,  or January 5, 1999,  at
Lender's option, and shall be deemed automatically  renewed for
successive terms of two (2) years  thereafter  unless 
terminated as of the end of the initial or any renewal term
(each a "Term") by the Lender or any Borrower  giving the other
parties  hereto  written notice at least sixty (60) days prior
to the end of the then-current Term.

         9.2 Any of the Borrowers may also  terminate  this 
Agreement by giving Lender at least thirty (30) days prior 
written  notice at any time upon payment in full of all of the 
Obligations  as  provided  herein,  including  the  early
termination  fee provided  below.  Lender shall also have the
right to terminate this  Agreement at any time upon or after the
occurrence of an Event of Default. If Lender  terminates this
Agreement upon or after the occurrence of an Event of Default, 
or if any of the Borrowers shall terminate this Agreement as
permitted herein effective prior to the end of the  then-current
 Term, in addition to all other  Obligations,  the Borrowers 
collectively  shall pay to Lender,  upon the effective  date  of
 termination,  in  view of the  impracticality  and  extreme

                                       28



 difficulty of ascertaining actual damages and by mutual
agreement of the parties as to a reasonable  calculation of
Lender's lost profits,  an early  termination fee equal to:

                  (a) fifty  percent (50%) of the average 
monthly  interest and         fees payable by the  Borrowers to
Lender with respect to the  Revolving         Loans for the
immediately  preceding six (6) months or from the date of       
 this Agreement, whichever is the shorter period, multiplied by

                  (b)  either  (i) the  number of months  (or
any part  thereof)         remaining in the then-current Term,
if the Borrowers' written notice of         termination is
received by Lender or termination by Lender is effective        
more than sixty (60) days prior to the end of the then-current 
Term or         (ii) the  number  of  months  (or any part 
thereof)  remaining  in the         then-current  Term  plus 
twenty-four  (24) if the  Borrowers'  written         notice of
termination is received by Lender or termination by Lender is   
     effective  within sixty (60) days prior to the end of the 
then-current         Term.

For  purposes of  calculating  the early  termination  fee, in
no event will the average monthly interest be less than the
interest which would have been payable if the  Revolving  Loans
had equaled the Minimum  Borrowing set forth in Section 10.1(d)
on each day during the calculation period.

         9.3 Borrowers may prepay,  in whole or in part, the
Term Loans prior to the end of the then current  Term.  If such 
prepayment is made with funds other than funds  obtained  from a
public  offering or private  placement of equity or debt by
Borrowers,  the  Borrowers  collectively  shall pay to Lender, 
upon the effective  date  of  termination,  in  view of the 
impracticality  and  extreme difficulty of ascertaining actual
damages and by mutual agreement of the parties as to a
reasonable  calculation of Lender's lost profits,  an early 
termination fee equal to:

                  (a) fifty  percent (50%) of the average 
monthly  interest and         fees payable by the  Borrowers to
Lender with respect to the Term Loans         for the 
immediately  preceding six (6) months or from the date of this  
      Agreement, whichever is the shorter period, multiplied by

                  (b)  either  (i) the  number of months  (or
any part  thereof)         remaining in the then-current Term,
if the Borrowers' written notice of         termination is
received by Lender or termination by Lender is effective        
more than sixty (60) days prior to the end of the then-current 
Term or         (ii) the  number  of  months  (or any part 
thereof)  remaining  in the         then-current  Term  plus 
twenty-four  (24) if the  Borrowers'  written         notice of
termination is received by Lender or termination by Lender is   
     effective  within sixty (60) days prior to the end of the 
then-current         Term.

         If such payment is made with funds  obtained from a
public  offering or private  placement of equity or debt by
Borrowers,  then, in lieu of the fee set forth in (a) and (b)
above,  Borrowers shall collectively pay to Lender an early
termination fee of $100,000.00.

         9.4 Upon  termination of this Agreement by the
Borrowers,  as permitted herein, in addition to payment of all
Obligations which are not contingent, each Borrower  shall 
deposit  such amount of cash  collateral  as Lender  reasonably
determines  is necessary to secure  Lender from loss,  cost, 
damage or expense, including reasonable attorneys' fees, in
connection with any open Accommodations

                                       29



 or remittance items or other payments  provisionally credited
to the Obligations and/or to which Lender has not yet received
final and indefeasible payment.

         9.5 Except as otherwise  provided,  all  notices, 
requests and demands hereunder  shall be (a) made to  Lender  at
its  address  set  forth in  Section 10.6(a) and to each
Borrower at its chief executive  office set forth in Section
10.6(d),  or to such other  address  as either  party may 
designate  by written notice to the other in accordance  with
this  provision,  and (b) deemed to have been given or made: if
by hand, immediately upon delivery; if by telex, telegram or
telecopy (fax),  immediately upon receipt;  if by overnight
delivery service, upon receipt;  and if by certified mail, 
return receipt requested five (5) days after mailing.

         9.6 If any  provision  of  this  Agreement  is held  to
be  invalid  or unenforceable,  such provision  shall not affect
this Agreement as a whole,  but this  Agreement  shall be
construed as though it did not contain the  particular provision
held to be invalid or unenforceable.

         9.7 Neither this  Agreement nor any provision  hereof
shall be amended, modified or  discharged  orally or by course
of  conduct,  but only by a written agreement  signed  by an 
authorized  officer  of  Lender  and  Borrowers.  This Agreement
 shall be binding upon and inure to the benefit of each of the
parties hereto and their respective  successors and assigns, 
except that any obligation of  Lender  under  this  Agreement 
shall  not be  assignable  nor  inure to the successors and
assigns of Borrowers.

         9.8 No  termination  of this  Agreement  shall relieve
or discharge any Borrower  of  its  Obligations,  grants  of 
Collateral,  duties  and  covenants hereunder or otherwise 
including,  without  limitation,  the  continuation  and
survival in full force and effect of all security  interests and
liens of Lender in and upon all then-existing and 
thereafter-arising or acquired Collateral and all warranties and
waivers of Borrowers,  until such time as all  Obligations to
Lender have been indefeasibly paid and satisfied in full.

         9.9 The  enumeration  herein of the Lender's rights and
remedies is not intended to be  exclusive,  and such rights and 
remedies are in addition to and not by way of  limitation  of
any other  rights or remedies  that the Lender may have under
the Uniform Commercial Code or other applicable law. The Lender
shall have the right, in its sole  discretion,  to determine
which rights and remedies are to be  exercised  and in which 
order.  The  exercise of one right or remedy shall not preclude
the exercise of any others, all of which shall be cumulative.
The Lender may, without limitation,  proceed directly against
the Borrowers,  or any of them,  to collect  the  Obligations 
without  any prior  recourse  to the Collateral.

         9.10  Whenever  an  Event of  Default  exists,  the 
Lender  is  hereby authorized  at any time and from time to
time,  to set off and apply any and all deposits (general or
special, time or demand,  provisional or final) at any time held
and other  indebtedness at any time owing by the Lender or any
affiliate of such Lender to or for the credit or the account of
any Borrower  against any and all of the Obligations, whether or
not then due and payable.

         9.11  Lender may grant the right to  participate  in
Loans and to enter into participation  agreements with one or
more participating  lenders;  and, in the event that Lender does
grant such right to participate in Loans,  Lender may do so with
such  participating  lenders,  and on such terms and 
conditions,  as

                                       30



 shall be acceptable to Lender. If a participating  lender shall
at any time with the Borrowers' knowledge participate with the
Lender in the Loans, each Borrower hereby  grants  to  such  
participating   lender,   and  the  Lender  and  such
participating  lender shall have and are hereby given, a
continuing  lien on and security  interest in any money, 
securities and other property of such Borrower in the custody or
possession of the participating lender,  including,  the right
of set-off,  to the extent of such participating  lender's 
participation in the Obligations,  and such  participating 
lender  shall be  deemed to have the same right of set-off to
the extent of such participating  lender's  participation in the
 Obligations  under  this  Agreement,  as it would  have if it
were a direct lender.

         9.12 All terms used herein which are defined in the
Uniform  Commercial Code shall have the meanings  given  therein
 unless  otherwise  defined in this Agreement  and all 
references  to the singular or plural herein shall also mean the
plural or singular, respectively.

         9.13 THIS  AGREEMENT  SHALL BE GOVERNED BY AND 
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE IN WHICH THE 
OFFICE OF LENDER  SET FORTH IN  SECTION 10.6(a) BELOW IS LOCATED.

         9.14 THIS AGREEMENT  (AND THE  PROMISSORY  NOTES
REFERRED TO IN SECTION 2.2),  ARE INTENDED BY THE BORROWERS  AND
THE LENDER TO BE THE FINAL,  COMPLETE, AND  EXCLUSIVE  
EXPRESSION  OF  THE  AGREEMENT  BETWEEN  THEM.  THIS  AGREEMENT
SUPERSEDES ANY AND ALL PRIOR ORAL OR WRITTEN AGREEMENTS 
RELATING TO THE SUBJECT MATTER HEREOF AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR
SUBSEQUENT  ORAL  AGREEMENTS  OF THE PARTIES.  NO  MODIFICATION,
 RESCISSION, WAIVER,  RELEASE, OR AMENDMENT OF ANY PROVISION OF
THIS AGREEMENT SHALL BE MADE, EXCEPT BY A WRITTEN  AGREEMENT 
SIGNED BY THE  BORROWERS  AND A DULY  AUTHORIZED OFFICER OF
LENDER.

         9.15 This Agreement may be executed in any number of
counterparts,  and by the Lender and the Borrowers in separate
counterparts, each of which shall be an  original,  but all of 
which  shall  together  constitute  on and  the  same agreement.

         9.16 The captions contained in this Agreement are for
convenience only, are without substantive meaning and should not
be construed to modify,  enlarge, or restrict any provision.

         9.17 This Agreement amends and restates in its entirety
the Second Loan Agreement  and the WellTech  Agreement.  The 
execution of this  Agreement,  the Promissory Notes, and the
other loan documents  executed in connection  herewith does not
extinguish  the  indebtedness  outstanding in connection 
therewith nor does it  constitute  a novation  with  respect to 
indebtedness  outstanding  in connection with the Original Loan
Agreement or the indebtedness evidenced by the Original Loan
Documents or the Second Loan Agreement or the WellTech 
Agreement. The Borrowers and Lender ratify and confirm each of
the Original Loan  Documents including each of the security 
documents executed pursuant to the Original Loan Agreement or
the Second Loan Agreement or the WellTech Agreement, and agree
that such  Original  Loan  Documents  as amended and modified 
hereby  continue to be legal, valid, binding and enforceable in
accordance with their respective terms. Without  limiting the
generality of the foregoing and  notwithstanding  any loan
document to the contrary,  each Borrower and Lender agree and
acknowledge  that:

                                       31



 (i) the term "Loan Agreement" as used in each loan document, 
including, but not limited to, each of the Promissory  Notes, 
means this Agreement;  (ii) the term "Indebtedness," 
"Obligations"  or  "Secured  Obligations"  as used in any  loan
document means the Obligations;  and (iii) the term "Lender" as
used in the Loan Documents means the Lender as defined herein.

         9.18  Releases.  As a material  inducement to Lender to
enter into this Agreement, each Borrower hereby represents and
warrants that there are no claims or offsets against, or
defenses or counterclaims to, the terms and provisions of and
the other  obligations  created or evidenced by the Original
Loan Documents, the Second  Loan  Agreement  or the  WellTech 
Agreement.  Each of the  Original Obligors  hereby  releases, 
acquits,  and forever  discharges  Lender,  and its current 
parent,  subsidiaries  and  affiliated  organizations,  and the
current offices,  employees,  attorneys and agents of each of
the foregoing (all of whom are herein jointly and severally
referred to as the "Released Parties") from any and all
liability, damages, losses, obligations, costs, expenses, suits,
claims, demands,  causes of action for damages or any other 
relief,  whether or not now known or suspected,  of any kind,
nature or character, at law or in equity, that any of them now
has or may have ever had  against any of the  Released  Parties,
including,  but not limited to,  those  relating  to (a) usury
or  penalties  or damages  therefor,  (b) allegations that a
partnership  existed between Borrower and the Released  Parties,
 (c) allegations of  unconscionable  acts,  deceptive trade 
practices,  lack  of  good  faith  or fair  dealing,  lack of 
commercial reasonableness   or  special   relationships,   such 
as  fiduciary,   trust  or confidential  relationships,  (d)
allegations of dominion,  control,  alter ego, instrumentality, 
fraud,  misrepresentation,  duress, coercion, undue influence,
interference  or  negligence,  (e)  allegations  of tortious 
interference  with present or present or prospective business 
relationships or of antitrust or (f) slander, libel or damage to
reputation  (hereinafter being collectively referred to as the
"Claims"), all of which Claims are hereby waived.

31,  June 30,                           September  30 and 
December  31)  based on the  prior

                                   SCHEDULE B

The following should be noted with respect to environmental
matters:

1.       WellTech  conducts its operations  from well servicing 
yards owned and         leased as  described  on Schedule 
10.6(e).  These  yards and  vehicles         located thereon are
subject to contamination  resulting from fueling of         the
rigs from  gasoline  and diesel  tanks  situated  on certain of
the         properties;  washing  the rigs using a mild 
detergent  with  resulting         flow-off and servicing the
rigs at the site using oil, grease and other         types of
lubricants.

2.       WellTech  conducts  liquid  hauling  operations  in
both  Oklahoma  and         Michigan.  These operations entail
the hauling of liquid substances and         wastes and the
disposal of such  substances in disposal wells permitted        
for this purpose.

3.       In connection  with the trucking  operations  mentioned
in No. 2 above,         WellTech has acquired three disposal
wells in the State of Michigan and         five disposal wells
in the State of Oklahoma.  These wells are properly        
permitted and caution is taken to deter unauthorized use of the
wells.

4.       Bronson  Production,  Inc.,  acquired the  Wlosinski 
No. 2-27 well in         Manistee  County,  Michigan in 1994
from Terra Energy,  Ltd. Terra has         entered  into  final 
administrative  consent  order  assessing  civil         penalty
against  respondent,  Terra Energy,  Ltd., on May 9, 1995. The  
      alleged  infractions  relate to injecting  into the well 
pressures in         excess of permissible pressures;  failing
to submit monthly, quarterly         and annual  monitoring 
reports;  and  failure  to post an  acceptable        
alternative  demonstration of financial  responsibility.  Terra
paid a         fine of approximately $35,000 and seeks
reimbursement from the Company          for a portion of the
amount paid.

5.       The Santa Maria, California property, formerly leased
and utilized last         in April 1992, by WellTech in its
California operations,  is subject to         limited
reclamation activities. While WellTech has not acknowledged any 
       liability or responsibility, approximately $15,000 has
been contributed         towards  efforts  with the 
representative  of the  property  owners to         satisfy  the
 Santa  Maria  County  Environmental  Agency.  There is an      
  understanding  that  the  efforts  will be  pursued  jointly 
to  avoid         litigation with the property owners.

WellTech owns and operates the following  above-ground  and
underground  storage tanks:

1.       Mid-Continent Region - Fuel Tanks

         There are only two underground tanks on property owned
or leased by the         Company at the El Reno, Oklahoma
facility in El Reno,  Oklahoma.  These         tanks were in the
 ground at the time  WellTech  acquired  the El Reno,        
Oklahoma  property  and have not been  used by the  Company 
since  the         acquisition. At the time of the acquisition,
the soils around the tanks         were  tested  and  no 
contamination  was  found  as  documented  in an        
environmental assessment delivered to the Company.

       

         Above the ground storage tanks are located in:

                  Canadian, Texas                  Countyline,
Oklahoma                  Guthrie, Oklahoma                 
Lindsay, Oklahoma                  Oklahoma City, Oklahoma

         Northeastern Region - Fuel Tanks

                  There are no underground tanks

                  A  single  above  the  ground   storage  tank 
is  located  at                  WellTech's well servicing yard
in Kalkaska, Michigan.

 



                                  SCHEDULE 6.12

 1.   Key has  guaranteed  the  obligations  of Odessa  to 
Norwest  Bank  Texas,     Midland.

2.   Key will pay the bonuses due to Francis D. John under Mr.
John's Employment     Agreement with Key.

3.   Key will guarantee WellTech's obligations relating to the
Nub's acquisition     and note balance: $200,000 - $250,000

4.   WellTech  leases  from  Hidco  Development  Corporation, 
which is owned by     Kenneth C. Hill and his spouse, real
property used for well servicing yards     in Mt. Pleasant,
Michigan and Ripley, West Virginia. Lease terms, including    
rental rates, are deemed by management to be competitive.

5.   WellTech leases from Talon  Development  Corporation real
property used for     its servicing yard in Indiana,
Pennsylvania.  Kenneth C. Hill owns a 33 1/3     interest in
Talon  Development  Corporation.  Lease terms including  rental 
   rates are deemed by management to be competitive.

6.   WellTech initiated a management incentive  compensation
plan which requires     the  payment  of sums of  money  to 
various  parties  contingent  upon the     attainment of a
stipulated  level of  profitability.  No payments have been    
made pursuant to this plan since its adoption.
