  Re:   Yale E. Key, Inc., Key Energy Drilling, Inc. d/b/a Clint
Hurt Drilling and WellTech Eastern, Inc. (the "Borrowers")



Ladies and Gentlemen:



         Reference  is  made  to the  financing  arrangements 
between  The  CIT Group/Credit  Finance,  Inc. ("Lender") and
Borrowers,  pursuant to which Lender may extend loans,  advances
and other financial  accommodations  to Borrowers as set forth
in the Third Amended and Restated Loan and Security Agreement
dated of even date herewith  between  Borrowers and Lender and
various other  agreements, documents  and  instruments  now or
at any time  executed  and/or  delivered  in connection 
therewith or otherwise related thereto,  including,  but not
limited to, this Guaranty (all of the foregoing,  as the same
now exist or may hereafter be amended,  modified,  supplemented,
 extended,  renewed, restated or replaced, being collectively
referred to herein as the "Financing Agreements").



         Due to the close business and financial relationships
between Borrowers and the undersigned  ("Guarantor"),  in
consideration of the benefits which will accrue to Guarantor, 
and as an inducement for and in consideration of Lender at any 
time   providing  or  extending   loans,   advances  and  other 
 financial accommodations  to Borrowers,  whether  pursuant to
the Financing  Agreements or otherwise, Guarantor hereby,
irrevocably and unconditionally, (a) guarantees and agrees to be
liable for the prompt indefeasible and full payment and
performance of all revolving loans,  term loans,  letters of
credit,  bankers'  acceptances, merchandise  purchase 
guaranties or other  guaranties or  indemnities  for each
Borrower's  account and all other  obligations,  liabilities and
indebtedness of every kind,  nature or  description  owing by
any Borrower to Lender  and/or its affiliates,  including
principal,  interest, charges, fees and expenses, however
evidenced,  whether as  principal,  surety,  endorser, 
guarantor or  otherwise, whether arising under any of the
Financing Agreements or otherwise,  whether now existing or 
hereafter  arising,  whether  arising  before,  during or after
the initial  or  any  renewal  term  of  the  Financing  
Agreements  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
Borrowers to others, assumption, operation of law, subrogation
or otherwise  and (b) agrees to pay to Lender on demand the
amount of all  expenses (including,  without limitation, 
attorneys fees and legal expenses) incurred by Lender in
connection with the preparation, execution, delivery, recording,

                                                        





administration,   collection,  liquidation,   enforcement  and 
defense  of  any Borrower's  obligations,  liabilities  and 
indebtedness as aforesaid to Lender, Lender's rights in any
collateral or under this Guaranty and all other Financing
Agreements  or in any way  involving  claims by or against 
Lender  directly  or indirectly  arising out of or related to
the relationship  between each Borrower and Lender,  Guarantor
and Lender, or any other Obligor (as hereinafter defined) and
Lender,  whether  such  expenses are  incurred  before,  during
or after the initial  or  any  renewal  term  of  the  Financing
  Agreements  or  after  the commencement  of any case with
respect to any  Borrower,  Guarantor or any other Obligor under
the United States  Bankruptcy  Code or any similar statute (all
of which being collectively referred to herein as the
"Guaranteed Obligations").

         Notice of acceptance of this  Guaranty,  the making of
loans,  advances and extensions of credit or other financial
accommodations to, and the incurring of any  expenses  by or in 
respect  of,  Borrowers,  and  presentment,  demand, protest, 
notice of  protest,  notice of  nonpayment  or  default  and all
other notices to which any  Borrower or  Guarantor  are or may
be entitled  are hereby waived.  Guarantor  also  waives  notice
 of, and  hereby  consents  to, (i) any amendment, modification,
 supplement, renewal, restatement or extensions of time of
payment of or increase  or  decrease  in the amount of any of
the  Guaranteed Obligations or to the Financing Agreements and
any collateral, and the guarantee made herein shall apply to the
Guaranteed  Obligations as so amended,  modified, supplemented, 
renewed,  restated or extended,  increased or decreased, (ii)
the taking, exchange,  surrender and releasing of collateral or
guarantees now or at any time held by or available to Lender for
the  obligations  of any Borrower or any  other  party  at any 
time  liable  for  or in  respect  of the  Guaranteed
Obligations (individually and collectively,  the "Obligors"),
(iii) the exercise of,  or  refraining  from the  exercise  of
any  rights  against  any  Borrower, Guarantor  or any other 
Obligor  or any  collateral,  and (iv) the  settlement,
compromise  or release  of, or the waiver of any  default  with 
respect to, any Guaranteed  Obligations.  Guarantor  agrees 
that the  amount of the  Guaranteed Obligations  shall not be
diminished  and the  liability of Guarantor  hereunder shall not
be otherwise impaired or affected by any of the foregoing.



         This Guaranty is a guaranty of payment and not of
collection. Guarantor agrees that Lender need not attempt to
collect any Guaranteed  Obligations  from the  Borrowers or any
other Obligor or to realize upon any  collateral,  but may
require  Guarantor to make immediate  payment of the  Guaranteed
 Obligations to Lender when due or at any time thereafter.
Lender may apply any amounts received in respect of the
Guaranteed  Obligations to any of the Guaranteed  Obligations,
in whole or in part  (including  reasonable  attorneys  fees and
legal  expenses incurred by Lender with respect thereto or
otherwise  chargeable to any Borrower or Guarantor) and in such
order as Lender may elect, whether or not then due.



         No invalidity,  irregularity or  unenforceability of
all or any part of the  Guaranteed  Obligations  shall  affect, 
impair  or be a  defense  to  this Guaranty,  nor shall any
other circumstance  which might otherwise  constitute a defense
available to, or legal or equitable discharge of any Borrower in
respect of any of the  Guaranteed  Obligations or Guarantor in
respect of this Guaranty, affect,  impair or be a defense  to
this  Guaranty.  Without  limitation  of the foregoing,  the 
liability of Guarantor  hereunder  shall not be  discharged  or
impaired  in any  respect  by reason of any  failure  by  Lender
to  perfect  or continue  perfection of any lien or security 
interest in any collateral for the Guaranteed  Obligations  or
any delay by Lender in  perfecting  any such lien or security
interest. As to interest, fees and expenses, whether arising
before 

                                        2





or after the  commencement  of any case with respect to any 
Borrower  under the United States Bankruptcy Code or any similar
statute,  Guarantor shall be liable therefor,  even if any
Borrower's liability for such amounts does not, or ceases to,
exist by operation of law.



         This Guaranty is absolute,  unconditional  and 
continuing.  Payment by Guarantor  shall be made to Lender at
its office  from time to time on demand as Guaranteed 
Obligations become due. One or more successive or concurrent
actions may be brought hereon against  Guarantor  either in the
same action in which the Borrowers or any of them, or any other
Obligors are sued or in separate actions.



         Payment of all amounts now or hereafter  owed to
Guarantor by Borrowers or any  other  Obligor  is  hereby 
subordinated  in  right  of  payment  to the indefeasible 
payment  in full to Lender of the  Guaranteed  Obligations  and
is hereby assigned to Lender as security therefor. Guarantor
hereby irrevocably and unconditionally  waives and relinquishes
all surety defenses including,  but not limited to, all 
statutory,  contractual,  common law,  equitable  and all other
claims against each Borrower,  any collateral for the Guaranteed
 Obligations or other  assets  of  each  Borrower  or  any 
other  Obligor,   for   subrogation, reimbursement, 
exoneration,  contribution,  indemnification,  setoff  or  other
recourse  in respect of sums paid or payable to Lender by 
Guarantor  hereunder, and  Guarantor  hereby  further 
irrevocably  and  unconditionally   waives  and relinquishes any
and all other benefits which Guarantor might otherwise directly
or indirectly receive or be entitled to receive by reason of any
amounts paid by or collected or due from  Guarantor,  any
Borrower or any other Obligor upon the Guaranteed Obligations or
realized from their property.



         All sums at any time owed by Lender to  Guarantor  or
to the  credit of Guarantor  and any  property of Guarantor on
which Lender at any time has a lien or security interest or of
which Lender at any time has possession, shall secure payment
and performance of all Guaranteed  Obligations and all other
obligations of Guarantor to Lender however arising.



         In case  proceedings  be  instituted  by or  against 
any  Borrower  or Guarantor  or  any  other   Obligor  in
bankruptcy   or   insolvency,   or  for reorganization, 
arrangement,  receivership,  or the like, or if any Borrower or
Guarantor  or any  other  Obligor  calls a  meeting  of 
creditors  or makes any assignment  for the benefit of 
creditors,  or upon the  occurrence of any event which
constitutes a default or event of default under the Financing 
Agreements, the liability of Guarantor for the entire 
Guaranteed  Obligations shall mature, even if the liability of
Borrowers or any other Obligor therefor does not.



         Guarantor  shall continue to be liable  hereunder until
one of Lender's officers actually receives a written 
termination  notice by certified mail; but the giving of such
notice shall not relieve  Guarantor  from  liability  for any
Guaranteed  Obligations  incurred  before  termination  or for 
post-termination collection  expenses  and  interest  pertaining
 to any  Guaranteed  Obligations arising before termination.



         Guarantor  agrees  that this  Guaranty  shall  remain
in full force and effect or be  reinstated,  as the case may be,
if at any time  payment of any of the  Guaranteed  Obligations 
is rescinded  or  otherwise  restored by Lender to Borrowers or
to any other person, who made such payment,  or to the creditors
or creditors representative of Borrowers or such other person.

                                        3





         Lender's  books and  records  showing the  account 
between  Lender and Borrowers  shall be  admissible in evidence
in any action or proceeding as prima facie proof of the items
therein set forth, and any written statements  rendered by
Lender to  Borrowers,  to the  extent to which no written 
objection  is made within sixty (60) days after the date
thereof,  shall be considered  correct and be binding on
Guarantor as an account stated for purposes of this Guaranty.



         No delay on Lender's part in exercising any rights
hereunder or failure to exercise the same shall constitute a
waiver of such rights.  No notice to, or demand  on,  Guarantor 
shall be  deemed  to be a waiver  of the  obligation  of
Guarantor to take further action without notice,  or demand as
provided  herein. No waiver of any of Lender's rights hereunder,
 and no modification or amendment of this Guaranty,  shall be
deemed to be made by Lender unless the same shall be in writing,
 duly signed on Lender's behalf, and each such waiver, if any,
shall apply only with  respect to the specific  instance 
involved and shall in no way impair  Lender's  rights or the 
obligations of Guarantor to Lender in any other respect at any
other time.



         This Guaranty is binding upon Guarantor, its successors
and assigns and shall benefit Lender and its successors, 
endorses,  transferees and assigns. If the  undersigned  are
more than one, this Guaranty shall be binding  jointly and
severally  upon them and their  respective  successors  and
assigns and the term "Guarantor"  wherever used herein shall
mean all the  undersigned and any one or more of them and their 
successors and assigns.  All references to Borrowers and Lender 
herein shall  include  their  respective  successors  and
assigns.  THIS INSTRUMENT  SHALL BE GOVERNED BY, AND  CONSTRUED
AND  INTERPRETED  IN ACCORDANCE WITH,  THE LAWS OF THE STATE IN
WHICH THE  OFFICE OF LENDER  SET FORTH  ABOVE IS LOCATED.



         GUARANTOR AND LENDER WAIVE ALL RIGHTS TO TRIAL BY JURY
IN ANY ACTION OR PROCEEDING  INSTITUTED  BY  EITHER OF THEM 
AGAINST  THE  OTHER  WHICH  PERTAINS DIRECTLY  OR  INDIRECTLY 
TO THIS  GUARANTY,  ANY  ALLEGED  TORTIOUS  CONDUCT BY GUARANTOR
OR LENDER,  OR, IN ANY WAY, DIRECTLY OR INDIRECTLY,  ARISING OUT
OF OR RELATED  TO THE  RELATIONSHIP  BETWEEN  GUARANTOR  AND
LENDER OR  BORROWERS  AND LENDER.  IN NO EVENT WILL LENDER BE
LIABLE FOR LOST PROFITS OR OTHER  SPECIAL OR CONSEQUENTIAL
DAMAGES.



         Guarantor  waives  all  rights to  interpose  any 
claims,  deductions, setoffs or  counterclaims  of any kind, 
nature or  description in any action or proceeding  instituted 
by Lender  with  respect to this  Guaranty or any matter arising
herefrom or relating hereto, except compulsory counterclaims.



         GUARANTOR HEREBY IRREVOCABLY  SUBMITS AND CONSENTS TO
THE NON-EXCLUSIVE JURISDICTION  OF THE STATE AND FEDERAL  COURTS
LOCATED IN THE STATE IN WHICH THE OFFICE OF LENDER  DESIGNATED 
ABOVE IS  LOCATED  WITH  RESPECT  TO ANY ACTION OR PROCEEDING 
ARISING  OUT OF THIS  GUARANTY  OR ANY MATTER  ARISING  HEREFROM
 OR RELATING HERETO.  ANY SUCH ACTION OR PROCEEDING  COMMENCED
BY GUARANTOR  AGAINST LENDER WILL BE LITIGATED ONLY IN A FEDERAL
COURT LOCATED IN THE DISTRICT, OR A

                                        4





STATE  COURT IN THE STATE AND  COUNTY,  IN WHICH THE  OFFICE OF
LENDER SET FORTH ABOVE IS  LOCATED  AND  GUARANTOR  WAIVES  ANY 
OBJECTION  BASED  ON  FORUM  NON CONVENIENS AND ANY OBJECTION TO
VENUE IN CONNECTION THEREWITH.



         In any such action or proceeding,  Guarantor waives
personal service of the summons and  complaint or other  process
and papers  therein and agrees that any process or notice of
motion or other  application to any of said Courts or a judge
thereof, or any notice in connection with any proceedings
hereunder may be served (i) inside or outside such State by
registered or certified mail,  return receipt  requested, 
addressed  to  Guarantor  at the address set forth below or

indicated in the records of Lender, and service or notice so
served shall be deemed complete five (5) days after the same
shall have been  posted or (ii) in such other  manner as may be
permissible under the rules of said Courts.



         THIS  WRITTEN  AGREEMENT  REPRESENTS  THE FINAL 
AGREEMENT  BETWEEN THE PARTIES AND MAY NOT BE  CONTRADICTED BY
EVIDENCE OF PRIOR,  CONTEMPORANEOUS,  OR SUBSEQUENT  ORAL 
AGREEMENTS  OF  THE  PARTIES.  THERE  ARE  NO  UNWRITTEN  ORAL
