2.3      Additional Purchase Price Adjustments and Procedures.


     (a) On the Closing Date, the Buyer will prepare and deliver to the Seller a
balance sheet of the Company as of July 31, 1997 (the "July 31 Balance  Sheet").
The July 31 Balance Sheet shall include all information necessary to compute the
Working Capital of the Company. The Buyer shall make available to the Seller all
information which may be in the possession of the Buyer or the Company which the
Seller  requests in order to verify the  accuracy of the July 31 Balance  Sheet.
Within 60 days following delivery of the July 31 Balance Sheet, the Seller shall
notify the Buyer whether it agrees with the July 31 Balance Sheet.  In the event
that the Seller  disagrees  with the July 31  Balance  Sheet,  the Seller  shall
provide the Buyer with a written  notice  specifying  the basis for the Seller's
disagreement,  and the  Seller  and the Buyer  shall work in good faith to reach
agreement on the  composition  of the July 31 Balance  Sheet,  but, in the event
that they  shall not agree  within 30 days  following  the date of such  written
notice, the matter will be referred to a "Big Six" independent public accounting
firm mutually agreed to by the Buyer and the Seller.  The fees and disbursements
of such accounting firm shall be borne equally by the Buyer and the Seller. Such
accounting  firm shall examine the records of the Company,  and,  within 30 days
following  the date upon which such matter shall be referred to such  accounting
firm,  such  accounting firm shall determine the disposition of any dispute with
respect to the July 31 Balance  Sheet  (the date on which the  determination  is
made, whether by the accounting firm or by agreement of the parties, is referred
to as the "Final Determination Date"). Any such determination shall be final and
binding on the  parties,  and may be enforced by  appropriate  judicial or other
proceedings.


     (b) In the event that the  Working  Capital of the Company is less than the
Estimated  Working Capital,  then the amount of such difference shall be paid by
the Seller to the Buyer  within  two  business  days of the Final  Determination
Date,  plus  interest  of 8% per annum  payable  from July 31, 1997 to the Final
Determination Date. In the event that the Working Capital of the Company is more
than the Estimated Working Capital,  then the amount of such difference shall be
paid  by the  Buyer  to  the  Seller  within  two  business  days  of the  Final
Determination  Date, plus interest of 8% per annum payable from July 31, 1997 to
the Final Determination Date.


     (c) The  July 31  Balance  Sheet  shall  be  prepared  in  accordance  with
generally accepted accounting principles applied in a manner consistent with the
Company's  historical  accounting  policies  and  practices;   except  that  all
intercompany balances will be eliminated.


     (d) On or prior to 90 days from the Closing  Date,  the Seller will prepare
and deliver to the Buyer a  calculation  of the State Tax  Detriment (as defined
below) resulting from the sale of the Company, showing all necessary information
for  such  calculation.  The  Seller  shall  make  available  to the  Buyer  all
information  which  may be in the  possession  of the  Seller  which  the  Buyer
reasonable  requests in order to verify the accuracy of the State Tax  Detriment
calculation.  Within 30 days following  delivery of the calculation of the State
Tax Detriment,  the Buyer shall notify the Seller whether it disagrees with such
calculation  and the Buyer shall be deemed to agree with such  calculation if no
notice of disagreement  is received  within such time period.  In the event that
the Buyer disagrees with such calculation,  the Buyer shall attach to its notice
of disagreement or incorporate therein a written notice specifying the basis for
the Buyer's disagreement,  and the Seller and the Buyer shall work in good faith
to reach  agreement  on the  calculation  but,  in the event that they shall not
agree within 30 days following the date of such written notice,  the matter will
be  referred to a  nationally  recognized  independent  public  accounting  firm
mutually agreed to by the Buyer and the Seller.  The fees and the  disbursements
of such accounting firm shall be borne equally by the Buyer and the Seller. Such
accounting  firm shall  examine the records of the Seller and the Company,  and,
within 30 days  following  the date upon which such matter  shall be referred to
such  accounting  firm,  such accounting firm shall determine the disposition of
any dispute with respect to the  calculation.  Any such  determination  shall be
final and binding on the parties, and may be enforced by appropriate judicial or
other  proceedings.  Payment of the amount of the State Tax  Detriment  shall be
made by the Buyer to the Seller no later than five  business days after the date
agreement  is reached  between  the Buyer and the Seller or the  decision of the
accounting firm is made. The "State Tax Detriment" equals the difference between
(A) the state Taxes  payable by the Seller or any  related  party as a result of
making the Section 338(h)(10)  election  contemplated by Section 5.11(c) of this
Agreement  and (B) the state  Taxes that would have been  payable as a result of
the sale pursuant to this Agreement had such a Section  338(h)(10)  election not
been made, such  calculation to be grossed up for any additional  state or other
Taxes payable as a result of the payment to the Seller under this provision.


     2.4 The Closing.  Except as otherwise set forth herein,  the closing of the
transactions  contemplated by this Agreement (the "Closing") shall take place at
the offices of the Seller in Houston,  Texas,  commencing  at 10:00 a.m.,  local
time, on (a) the later to occur of (i) a date between  October 1 and October 15,
1997 or (ii) the fifth business day following the  satisfaction or waiver of all
conditions  to the  obligations  of the parties to consummate  the  transactions
contemplated   hereby  (other  than  conditions  with  respect  to  actions  the
respective  parties will take at the Closing itself) or (b) such earlier date as
the Seller may  reasonably  request and the parties may  mutually  agree,  which
agreement shall not be unreasonably withheld (the "Closing Date").

     2.5 Deliveries at the Closing. At the Closing,  (a) the Seller will deliver
or cause to be  delivered  to the Buyer  certificates  representing  the Company
Stock and the various  certificates,  instruments  and documents  referred to in
Section  6.1; (b) the Buyer and Key Energy will deliver or cause to be delivered
to the Seller the various certificates, instruments and documents referred to in
Section  6.2;  and (c) the Buyer will  deliver or cause to be  delivered  to the
Seller the Purchase Price.


     2.6 Other Agreements. Concurrently herewith, (a) Nabors Industries, Inc. is
entering  into the  Guarantee,  (b) the  Seller,  the Buyer and Key  Energy  are
entering into the Operating  Agreement and (c) the Seller, the Buyer, Key Energy

10-K of Key Energy for the fiscal year ended June 30, 1996,  (ii) its  Quarterly
Reports  on Form  10-Q for the  quarterly  periods  ended  September  30,  1996,
December 31, 1996 and March 31,  1997,  (iii) its Proxy  Statement  for its last
Annual Meeting of  Shareholders,  (iv) its Current  Reports on Form 8-K as filed

Energy  Reports are the only reports,  schedules,  forms,  statements  and other
documents  required  by the  Exchange  Act to be  filed by Key  Energy  with the
Commission  since  June 30,  1996.  None of the Key Energy  Reports,  including,
without limitation,  any financial  statements or schedules included therein, at
the time filed,  contained any untrue statement of a material fact or omitted to
state any material fact  required to be stated  therein or necessary in order to
make the statements contained therein, in light of the circumstances under which
they were made, not misleading.  The audited  consolidated  financial statements
and  unaudited   consolidated   interim  financial   statements  of  Key  Energy
(collectively,  "Key Energy  Financial  Statements")  included  in such  reports
present fairly, in conformity in all material  respects with generally  accepted
accounting  principles  (except as may be  indicated  in the notes  thereto  and
except that certain  information  and disclosure  normally  included in notes to
consolidated  financial  statements  have been  condensed  or  omitted  from the
unaudited  consolidated  interim  financial  statements  pursuant  to rules  and
regulations of the Commission,  but any resultant  disclosures are in accordance
with  generally  accepted  accounting   principles  as  they  apply  to  interim
reporting),  the consolidated  financial  position of Key Energy as of the dates
thereof  and its  consolidated  results  of  operations  and cash  flows for the
periods then ended (subject to normal year-end audit  adjustments in the case of
any unaudited interim financial statements).

     4.10 Material Adverse Effect. Since March 31, 1997, other than as described
in the Key Energy Reports,  no event has occurred,  or condition  exists,  which
would constitute or cause,  individually or in the aggregate, a Material Adverse
Effect with respect to Key Energy.

expense of the  requesting  party  (unless the  requesting  party is entitled to
indemnification  therefor  under  Article 8 or unless  the party  subject to the
request is otherwise obligated to take such action pursuant to the terms of this
Agreement).  To  the  extent  necessary  for  Tax,  accounting,   collection  of
receivables  assigned  to Oxy  pursuant  to  Section  5(b) of the  Oxy  Purchase
Agreement,   benefits  administration  or  other  reasonable  business  purposes

Agreement or (b) any fact, situation, circumstance, status, condition, activity,
practice,  plan,  occurrence,   event,  incident,  action,  failure  to  act  or
transaction  on or prior to the Closing Date  involving  the Company,  the other
party  will  cooperate  with the  contesting  or  defending  party  (or Oxy,  as
applicable)  and its  counsel in the  contest or  defense,  make  available  its
personnel,  and provide  such  testimony  and access to its books and records as
shall be necessary in  connection  with the contest or defense,  all at the sole
cost and expense of the  contesting or defending  party (or Oxy, as  applicable)
(unless  the  contesting  or  defending  party is  entitled  to  indemnification
therefor under Article 8).

5.11     Tax Matters.

     (a) The Buyer shall pay all transfer Taxes,  including sales,  use, excise,

similar Taxes and filing fees and similar charges  resulting from this Agreement
or the transactions  contemplated hereby (including,  if applicable, an election
under Section 338(h)(10) of the Code), regardless of upon whom such transfer Tax
is levied or imposed by law. The Seller  shall be liable for all Taxes  relating
to the Company for taxable  periods  ending on or before the Closing  Date.  The
Buyer shall be liable for all Taxes  imposed with  respect to the Company  which
are attributable to any taxable periods after the Closing Date. In the event the
Tax year of the Company  does not end on the Closing Date for one or more Taxes,
the  Seller  shall  pay such  Taxes as are  attributable  to the  period  before
Closing,  as if such Tax year had ended on the Closing Date. The Seller shall be
responsible  for filing,  or causing to be filed,  all income or  franchise  Tax
Returns which are required to include the income, deduction and credits, etc. of
the Company for any tax period ending before, on or with the Closing Date. After
the Closing  Date,  the parties  shall  cooperate  with each other (and,  to the
extent required in Section 5(g) of the Oxy Purchase Agreement,  with Oxy) in the
preparation of any pre-closing or post-closing Tax Returns.


     (b)  In  the  case  of  any   audit,   examination   or  other   proceeding
("Proceedings")  with  respect to Taxes for which the Seller is or may be liable
pursuant to this  Agreement,  the Buyer shall  promptly  inform the Seller,  and
shall afford the Seller, at the Seller's expense, the opportunity to control the
conduct of such  Proceeding.  The Buyer  shall  execute or cause to be  executed
powers of attorney or other documents necessary to enable the Seller to take all
actions desired by the Seller with respect to such Proceeding to the extent such
Proceeding may affect amount of Taxes for which the Seller is liable pursuant to
this Agreement. The Seller shall have the right to control any such Proceedings,
and,  if there is  substantial  authority  thereof,  to  initiate  any claim for
refund,  file  any  amended  return  or take  any  other  action  which it deems
appropriate with respect to such Taxes. Any Proceeding with respect to Taxes for
a period which includes but does not end on the Closing Date shall be controlled
jointly by the Seller and the Buyer.


     Notwithstanding the foregoing, the Seller shall not agree to any settlement
concerning  Taxes for any taxable  period  ending on or before the Closing  Date
which may result in a material  increase in Taxes for any taxable  period ending
after the Closing Date without the prior written consent of the Buyer.


     (c) The Seller,  the Company and their Affiliates,  as of the Closing Date,
shall terminate all Tax allocation  agreements or other Tax sharing arrangements
with respect to the Company,  shall cause such  agreements or arrangements to be
of no further  force and effect as regards  the Company on and after the Closing
Date and there shall be no further liability of the Company  thereunder from and
after the Closing Date.


     (d) The  Buyer  and  the  Seller  shall  join in an  election  to have  the
provisions of Section  338(h)(10) of the Code and similar provisions of federal,
state, local or foreign law (where  permissible) apply to the acquisition by the
Buyer of the Company  Stock  whereby  (i) the Company  will be treated as having
sold all of its assets in a single  transaction  as of the close of  business on
the Closing Date while a member of the Seller's  consolidated Tax group and (ii)
no gain or loss will be  recognized by the Seller or the Company with respect to
the sale of Company Stock by the Seller. The election will include the execution
and subsequent  filing of Internal  Revenue  Service Form 8023-A pursuant to the
requirements as stated therein.  The Buyer shall,  within 60 days of the Closing
Date, provide to the Seller an allocation of the deemed purchase price among the
assets of the  Company in  accordance  with Code  Sections  338 and 1060 and any
comparable  provisions  of state,  local or foreign  law, as  appropriate.  Such
allocation shall be deemed acceptable to the Seller unless it notifies the Buyer
of any objections  within 30 days of receipt of such  allocation.  If the Seller
and the Buyer  are  unable to agree on such  allocation  within  120 days of the
Closing Date,  then an independent  accounting  firm mutually  acceptable to the
parties  hereto  shall  make  a  binding  determination  with  respect  to  such
allocation,  the fees and expenses of which shall the paid equally by the Seller
and the Buyer.


     (e) The Buyer,  Key Energy and the Seller shall  preserve all  information,
returns,  books,  records and documents relating to any liabilities for Taxes of
the Company with respect to a taxable  period until the later of  expiration  of
all  applicable  statutes  of  limitation  and  extensions  thereof  or a  final
determination with respect to Taxes of the Company for such period.

CONTAINED  IN THIS  AGREEMENT,  AND  THAT  IT HAS  MADE  ALL  SUCH  REVIEWS  AND
INSPECTIONS OF THE FOREGOING AS ITS HAS DEEMED NECESSARY OR APPROPRIATE. Nothing
in this Section 5.12 shall relieve the Seller or the Company of any liability or
responsibility  for  its  representations,  warranties  and  covenants  in  this
Agreement.

     5.13 Acquisition Proposals. The Seller will not, and will cause the Company
not to, directly or indirectly at any time before  termination of this Agreement

Seller's judgment,  to conduct a reasonable  investigation within the meaning of
the Securities Act.

this Section 5.14 are  transferable  to any Affiliate of the Seller to which the
Registered Securities may be transferred and to any single purchaser of all (but
not less than all) of the Registrable  Securities,  provided, in each case, that
the Affiliate or the purchaser agrees (in a writing that names the Company as an
explicit third party beneficiary) to be bound by all the terms and provisions of

Seller  proposes to sell any  Registered  Securities  pursuant to Rule 144,  Key
Energy shall  cooperate with the Seller so as to enable such sales to be made in
accordance with applicable laws, rules and regulations,  the requirements of Key
Energy's  transfer agent, and the reasonable  requirements of the broker through
which the sales are proposed to be executed.  Without limiting the generality of
the foregoing, Key Energy shall, upon request, furnish with respect to each such
sale (i) a written  statement  certifying  that Key Energy has complied with the
public information  requirements of Rule 144 and (ii) an opinion of Key Energy's
counsel   regarding  such  matters  as  Key  Energy's  transfer  agent  or  such
stockholder's broker may reasonably desire to confirm.

     For  purposes of this  Section  5.14(h),  the "Seller"  shall  include any
Affiliate of the Seller or other Person to which the  Registered  Securities and
registration  rights with respect thereto are transferred.  Also for purposes of
this Section 5.14(h),  Registered Securities shall refer to any capital stock of
Key Energy or its  successors  into which Key Energy  shares may be exchanged or
converted.

         (i)      Indemnification.


     (i) Key Energy will, and hereby does,  indemnify and hold harmless,  to the
extent permitted by applicable law, the Seller,  its officers and directors,  if
any,  and each Person,  if any,  who  controls the Seller  within the meaning of
Section 15 of the Securities Act, and their respective  successors,  against all
losses,  claims,  damages,  liabilities (or proceedings in respect  thereof) and
expenses,  including legal fees incurred in  investigating or defending any such
loss,  claim,  damage or liability  (under the  Securities  Act or common law or
otherwise)  arising out of or based upon any untrue  statement or alleged untrue
statement of a material fact  contained in any Shelf  Registration  Statement or
prospectus  (and as amended or  supplemented  if Key Energy shall have furnished
any amendments or supplements thereto),  covering the Registrable  Securities or
any preliminary  prospectus or other document incident thereto or arising out of
or based upon any omission or alleged  omission to state therein a material fact
required to be stated  therein or necessary to make the  statements  therein not
misleading,  except insofar as such losses,  claims,  damages,  liabilities  (or
proceedings  in respect  thereof) or expenses arise out of or are based upon any
untrue statement or alleged untrue statement  contained in or by any omission or
alleged  omission  from  information  furnished  in writing to Key Energy by the
Seller expressly for use therein.  Such indemnity shall remain in full force and
effect regardless of any investigation  made by or on behalf of the Seller,  its
officers, directors or any Person, if any, who controls the Seller as aforesaid,
and shall survive the transfer of such securities by the Seller.


     (ii) The Seller will and hereby does  indemnify and hold  harmless,  to the
extent  permitted by applicable law, Key Energy,  its officers and directors and
each Person, if any, who controls Key Energy within the meaning of Section 15 of
the Securities Act, and their respective successors, against all losses, claims,
damages, liabilities (or proceedings in respect thereof) and expenses, including
legal fees incurred in investigating or defending any such loss,  claim,  damage
or liability  (under the Securities Act or common law or otherwise)  arising out
of or based upon any untrue  statement or alleged untrue statement of a material
fact or any omission or alleged omission of a material fact required to be state
in any Shelf Registration  Statement or prospectus or preliminary  prospectus or
any amendment  thereof or supplement  thereto or other document incident thereto
or  arising  out of or based upon any  omission  or  alleged  omission  to state
therein a material  fact,  or  necessary to make the  statements  therein by the
Seller not  misleading,  but only to the extent  that such untrue  statement  is
contained in, or such omission is in, information  furnished in a writing by the
Seller  expressly  for use  therein,  provided  that  the  Seller's  obligations
hereunder  shall be limited to an amount  equal to the proceeds to the Seller of
the Registrable Securities sold pursuant to such registration statement.


     (iii) Any Person entitled to  indemnification  under the provisions of this
Section 5.14(i) shall (A) give prompt notice to the  indemnifying  Person of any
claim  with  respect  to which it seeks  indemnification  and (B) unless in such
indemnified  Person's  reasonably  judgment a conflict of interest  between such
indemnified and indemnifying  Persons may exist in respect to such claim, permit
such  indemnifying  Person to assume the  defense of such  claim,  with  counsel
reasonably  satisfactory to the indemnified  Person;  and, if such defense is so
assumed,  such indemnifying  Person shall not enter into any settlement  without
the consent of the indemnified Person if such settlement attributes liability to
the indemnified  Person and such indemnified  Person shall not be subject to any
liability  for any  settlement  made without  such  consent  (which shall not be
unreasonably  withheld).  In the event that an indemnifying  Person shall not be
entitled,  or elects not, to assume the  defense of a claim,  such  indemnifying
Person  shall not be  obligated  to pay the fees and  expenses  of more than one
counsel or firm of counsel  for all  parties  indemnified  by such  indemnifying
Person in respect of such claim,  unless, in the reasonable judgment of any such
indemnified  Person,  a conflict of interest may exist between such  indemnified
Person and any other of such indemnified Persons in respect of such claim.


     (iv) If for any  reason  the  foregoing  indemnity  is  unavailable,  then,
subject to the proviso in Section  5.14(i)(ii)  in the case of the  Seller,  the
indemnifying  Person  shall  contribute  to the  amount  paid or  payable by the
indemnified Person as a result of such losses, claims,  damages,  liabilities or
expenses  (A) in such  proportion  as is  appropriate  to reflect  the  relative
benefits received by the indemnifying Person on the one hand and the indemnified
Person on the other or (B) if the allocation provided by clause (A) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits  received by the indemnifying  Person on the one hand
and the  indemnified  Person  on the other  but also the  relative  fault or the
indemnifying  Person and the  indemnified  Person as well as any other  relevant
equitable  considerations.  The relative fault of the indemnifying Person on the
one hand and of the  indemnified  Person on the  other  shall be  determined  by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged  omission to state a material fact
relates to information supplied by the indemnifying Person or by the indemnified
Person and by the Persons' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The amount paid or
payable by a Person as a result of the losses, claims, damages,  liabilities and
expenses  shall be  deemed  to  include  any  legal or  other  fees or  expenses
reasonably  incurred by the Person in connection with investigating or defending
any action or claim.  No Person guilty of fraudulent  misrepresentation  (within
the  meaning of  Section  11(f) of the  Securities  Act)  shall be  entitled  to
contribution   from  any  Person   who  was  not   guilty  of  such   fraudulent
misrepresentation.


     (v) An indemnifying  Person shall make payments of all amounts  required to
be made pursuant to the foregoing  provisions of this Section  5.14(i) to or for
the account of the indemnified Person from time to time promptly upon receipt of
bills or invoices relating thereto or when otherwise due or payable.


     (j) Suspension of Resales. Key Energy shall be entitled to require that the
Seller  refrain  from  effecting  any  public  sales  or  distributions  of  the
Registered  Securities,  pursuant to the Shelf  Registration  Statement that has
been  declared  effective  by the  Commission,  if the board of directors of Key
Energy in good faith  determines that such public sales or  distributions  would
interfere in any material respect with any transaction involving Key Energy that
is  material  to Key  Energy.  The board of  directors  shall,  as  promptly  as
practicable,  give the  Seller  written  notice of any such  development,  which
notice  also  shall  contain  a  general  statement  of  the  reasons  for  such
restriction  on use and an estimate of the  anticipated  length of the period of
the  restriction.  In the event of a request by the board of directors  that the
Seller  refrain  from  effecting  any  public  sales  or  distributions  of  the
Registered  Securities,  Key Energy shall be required to lift such  restrictions
regarding  effecting public sales or distributions of the Registered  Securities
as soon as reasonably  practicable  after the board of directors shall determine
that public sales or  distributions  by the Seller of the Registered  Securities
shall  not  interfere  with  such  transaction;  provided,  that in any event no
requirement that the Seller refrain from effecting public sales or distributions
in the Registered  Securities shall extend for more than 15 days at any one time
or more than 30 days over the entire period the Shelf Registration  Statement is
required to be in effect.


     5.15 Books and Records.  Until April 30, 2001 (or for such longer period as
may be required by law), no party or any of its Affiliates shall destroy or give
up  possession  of an original or any copy of the books and records  relative to
any  matter  for  which a party or its  Affiliates  shall  have  any  continuing
responsibility  under this Agreement or the Oxy Purchase Agreement without first
offering the other parties the  opportunity,  at their  expense,  to obtain such
original or copy thereof.

notice  to the  Seller  if the  Closing  shall  not have  occurred  on or before
December  31,  1997 and as a result of the  failure of any  condition  precedent
under Section 6.1;  provided that the Buyer or Key Energy gave written notice of
the  failure to Seller and the  Seller  has not cured  such  failure  within ten

under Section 6.2;  provided that the Seller gave written  notice of the failure
to Buyer and Key Energy and they have not cured such failure within ten business

funds from the amount  deposited  under the Escrow  Agreement  to a bank account
designated  by the  Seller.  Such  $5,000,000  payment  shall  be as  liquidated

is an applicable  survival period pursuant to Section 8.1, and provided that the
Seller makes a written claim for indemnification against the Buyer or Key Energy
pursuant  to Section  9.7 within such  survival  period,  then the Buyer and Key
Energy, jointly and severally, agree to indemnify,  defend and hold harmless the
Seller from and against any Adverse  Consequences  the Seller may suffer through

Consequences  the  Seller may suffer  after the end of any  applicable  survival

     (a) If any third party  shall  notify any Party (the  "Indemnified  Party")
with  respect to any  matter (a "Third  Party  Claim")  which may give rise to a
claim for  indemnification  against any other Party (the  "Indemnifying  Party")
under this  Article 8, then the  Indemnified  Party shall  promptly  notify each
Indemnifying Party thereof in writing; provided that no delay on the part of the
Indemnifying  Party in  notifying  any  Indemnifying  Party  shall  relieve  the
Indemnifying Party from any obligation hereunder.

Third  Party Claim with  counsel of its choice  reasonably  satisfactory  to the
Indemnified  Party at any time  within 30 days after the  Indemnified  Party has

Party must conduct the defense of the Third Party Claim  actively and diligently
thereafter in order to preserve its rights in this regard;  and provided further
that the Indemnified  Party may retain separate  co-counsel at its sole cost and
expense and participate in the defense of the Third Party Claim.


     (d) So long as the  Indemnifying  Party has assumed and is  conducting  the
defense of the Third Party Claim in  accordance  with  Section  8.4(b),  (i) the
Indemnifying  Party will not consent to the entry of any  judgment or enter into
any  settlement  with respect to the Third Party Claim without the prior written
consent of the Indemnified  Party (not to be withheld  unreasonably)  unless the
judgment or proposed  settlement  involves  only the payment of money damages by
one or more of the  Indemnifying  Parties and does not impose an  injunction  or
other equitable relief upon the Indemnified Party and (ii) the Indemnified Party
will not consent to the entry of any judgment or enter into any settlement  with
respect  to the Third  Party  Claim  without  the prior  written  consent of the
Indemnifying Party (not to be withheld unreasonably).


     8.5 Matters Involving the Parties. In the event an Indemnified Party should
have a claim against an  Indemnifying  Party  hereunder  that does not involve a
Third Party Claim,  the  Indemnified  Party shall  transmit to the  Indemnifying
Party a written notice  describing in reasonable detail the nature of the claim,
an estimate of the amount of damages attributable to such claim and the basis of
the Indemnified Party's request for indemnification under this Agreement. If the
Indemnifying  Party does not notify the Indemnified  Party within 30 days of its
receipt of such notice that the  Indemnifying  Party  disputes  such claim,  the
claim shall be deemed a Liability of the Indemnifying  Party hereunder and shall
be paid within 30 days of the expiration of the initial  30-day  period.  If the
Indemnifying  Party has timely  disputed  such  claim as  provided  above,  such
dispute shall be resolved by litigation as provided herein.

8.6      Limitations on Indemnification.

     (a) No party  shall be  entitled to  indemnification  hereunder  unless and
until the aggregate of all amounts for which indemnity would otherwise be due to
such  party  exceeds  $100,000,  in  which  case  such  other  parties  shall be
responsible for all amounts of such liability  excluding such threshold  amount;
provided  that (i) the Seller  shall be  indemnified  for the full amount of any
Adverse  Consequences  pursuant  to Section  8.3(b) and (ii) each party shall be
indemnified for the full amount of any Taxes for which the other party is liable
pursuant to Section  5.11,  in each case  without  regard to any such  threshold
amount.


     (b) Notwithstanding  anything to the contrary, no party shall be liable for
Adverse Consequences  pursuant to this Article 8 in excess of the Purchase Price
(with stock and warrants  valued at the Closing Date) except for liabilities for
Adverse  Consequences  pursuant to Section  8.3(b) and Taxes pursuant to Section
5.11.


8.7      Environmental Claims.


     Notwithstanding   anything  in  this   Agreement  to  the   contrary,   and
notwithstanding the fact that any  representation,  warranty or covenant in this
Agreement  might be interpreted to cover the same, this Section 8.7 shall be the
sole and exclusive  provision of this Agreement,  and represents the Buyer's and
Key Energy's sole and exclusive  remedy against the Seller or any of its current
Affiliates with respect to Environmental Claims. To the extent the Seller or any
of its current  Affiliates is (i) an indemnified party for Environmental  Claims
under the Oxy Purchase  Agreement  and (ii) actually  receives  payment from Oxy
after  following  the  reasonable  instructions  of the Buyer to prosecute  such
Environmental  Claims,  at the sole expense of the Buyer, in accordance with the
provisions  of the Oxy  Purchase  Agreement,  the Seller shall remit any amounts
recovered,  less unrecovered costs to prosecute any Environmental  Claim, to the
Buyer in full payment for such Environmental  Claim. In the event (1) the Seller
or  any  of  its  current  Affiliates  (A)  is  not  an  indemnified  party  for
Environmental  Claims  under  the Oxy  Purchase  Agreement  or (B) is  unable to
recover any amount thereunder or (2) any Environmental Claim arises with respect
to the period  between  April 30, 1996 and the Closing  Date,  the Buyer and Key
Energy will have no recourse  against  the Seller or its  Affiliates,  and shall
indemnify, defend and hold the Seller and its Affiliates harmless therefor.


                            ARTICLE 9. MISCELLANEOUS.


     9.1 Press  Releases  and Public  Announcements.  Neither  the Buyer nor Key
Energy shall issue any press release or make any public announcement relating to

Seller;   provided,   however,  that  the  foregoing  shall  not  apply  to  any
announcement or written statement which, upon written advice of counsel provided

or breach of warranty or covenant  hereunder,  whether intentional or not, shall
be deemed to extend to any prior or  subsequent  default,  misrepresentation  or
breach of warranty or covenant hereunder or affect in any way any rights arising

referred to in such  Disclosure  Schedule is  incorporated  by  reference in the
representation and warranty to which such schedule relates. No representation or

terms or otherwise are breached.  Accordingly,  each of the parties  agrees that
the other parties shall be entitled to an injunction or  injunctions  to prevent
breaches of the  provisions of this Agreement and to enforce  specifically  this
Agreement and the terms and  provisions  hereof in any action  instituted in any
court of the United States or any state  thereof  having  jurisdiction  over the
parties  and the  matter,  in  addition  to any other  remedy to which it may be
entitled, at law or in equity.

     9.14  Submission  to  Jurisdiction.  Each  of the  parties  submits  to the
jurisdiction  of any state or federal  court  sitting in  Houston,  Texas in any
action or  proceeding  arising out of or relating to this  Agreement  and agrees

proceeding arising out or relating to this Agreement in any other court. Each of
the parties waives any defense of  inconvenient  forum to the maintenance of any
action or proceeding so brought and waives any bond, security, or other security
